Item 1.01

Entry Into a Material Definitive Agreement

Transaction with National Commerce Corporation

Agreement and Plan of Merger

On November 23, 2018, CenterState Bank Corporation, a Florida corporation (“CenterState”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with National Commerce Corporation, a Delaware corporation (“NCC”), whereby NCC will be merged with and into CenterState (the “Merger”). Pursuant to and simultaneously with entering into the Merger Agreement, CenterState’s wholly owned subsidiary bank, CenterState Bank, N.A. (“CenterState Bank”), and NCC’s wholly owned subsidiary bank, National Bank of Commerce (“NBC”), entered into a Plan of Merger and Merger Agreement whereby NBC will be merged with and into CenterState Bank immediately following the merger of NCC with and into CenterState (the “Bank Merger”).

Pursuant to the Merger Agreement, each outstanding share of NCC common stock issued and outstanding immediately prior to the effective time of the Merger will be entitled to receive 1.65 shares (the “Exchange Ratio”) of CenterState common stock, provided that cash in lieu of any fractional shares of CenterState common stock will be paid. Each outstanding share of CenterState common stock shall remain outstanding and unaffected by the Merger. Each option or warrant to purchase shares of NCC common stock will be assumed by CenterState according to its terms and be converted into an option or warrant, as applicable, to purchase the number of shares of CenterState common stock equal to the product obtained by multiplying the Exchange Ratio by the number of shares of NCC common stock which such NCC stock option or warrant, as applicable, entitled the holder thereof to purchase, at an exercise price equal to the quotient obtained by dividing the exercise price per share of the NCC stock option or warrant, as applicable, by the Exchange Ratio. The deferrals of NCC common stock representing equity awards and director fees credited to participant accounts under the National Commerce Corporation Deferral of Compensation Plan shall be converted into the right to receive the merger consideration in respect of each such deferred share, net of withholding taxes. Each performance share award with respect to shares of NCC common stock shall vest in accordance with the applicable NCC equity plan and award agreement and be entitled to receive the merger consideration as a deferred share (to be treated as described above) or an outstanding share of common stock, as applicable.

The Merger Agreement has been unanimously approved by the boards of directors of CenterState and NCC. The transaction is expected to close in the second quarter of 2019 subject to customary conditions, including receipt of all applicable regulatory approvals and the approval of the stockholders of NCC and the shareholders of CenterState.

The Merger Agreement also provides that upon completion of the Merger three current NCC directors (who will be mutually agreed to by CenterState and NCC) will be added to the board of directors of each of CenterState and CenterState Bank and that one additional NBC director (who will be mutually agreed to by CenterState and NCC) will be added solely to the board of directors of CenterState Bank.

Upon completion of the Merger, John C. Corbett shall continue to serve as the President and Chief Executive Officer of CenterState, and Mark W. Thompson shall continue to serve as the President of CenterState Bank. The Merger Agreement provides that upon completion of the Merger, Richard Murray, IV, the current Chairman and Chief Executive Officer of NCC, shall become and serve as the Chief Executive Officer of CenterState Bank, and William E. Matthews, V, the current President and Chief Financial Officer of NCC, shall become and serve as the Chief Financial Officer of CenterState and CenterState Bank. Jennifer L. Idell, the current Chief Financial Officer of CenterState and CenterState Bank, will serve as the Chief Administrative Officer of CenterState and CenterState Bank effective upon the closing of the Merger.

The Merger Agreement contains usual and customary representations and warranties that CenterState and NCC made to each other as of specific dates. The assertions embodied in those representations and warranties were made solely for purposes of the contract between CenterState and NCC and may be subject to important qualifications and limitations agreed to by the parties in connection with negotiating certain terms. Moreover, certain of the representations and warranties are subject to a contractual standard of materiality that may be different from what may be viewed as material to shareholders, and the representations and warranties may have been used to allocate risk between CenterState and NCC rather than establishing matters of fact. Each party also has agreed to customary covenants, including, among others, covenants relating to the conduct of its business during the interim period between the execution of the Merger Agreement and the consummation of the Merger.

The Merger Agreement may be terminated in certain circumstances, including: (i) by mutual written agreement of the parties, (ii) by either party if any regulatory approval required for consummation of the transactions contemplated by the Merger Agreement has been denied by final non-appealable action by the relevant governmental authority or the application therefor has been permanently withdrawn at the request of the relevant governmental authority, unless the failure to obtain such regulatory approval shall be due to the failure of the party seeking to terminate the Merger Agreement to perform or observe the covenants and agreements set forth in the Merger Agreement, (iii) by either party (provided that the party seeking termination is not then in material breach of its obligations to recommend the transaction or, in the case of NCC, in breach of its non-solicitation obligations) if the approval of the stockholders of NCC or the shareholders of CenterState is not obtained, (iv) by either party (provided that the party seeking to terminate is not then in material breach of any representation, warranty or covenant) in the event of a material breach by the other party of any representation, warranty or covenant contained in the Merger Agreement and such breach is not cured within thirty days or, if earlier, two business days prior to November 23, 2019, (v) by either party if the

Merger is n ot consummated on or before November 23, 2019, unless the failure of the closing to occur by such date is the result of a material breach of the Merger Agreement by the party seeking to terminate the Merger Agreement, (vi) by CenterState if NCC has breache d its non-solicitation obligations or NCC’s board of directors breaches its obligations with respect to giving notice of and making a recommendation in connection with the NCC stockholder meeting, (vii) by NCC if CenterState’s board of directors breaches i ts obligations with respect to giving notice of and making a recommendation in connection with the CenterState shareholder meeting, or (viii) by NCC if the price of CenterState common stock decreases in comparison to the specified ratios provided in the Me rger Agreement and CenterState elects not to increase the merger consideration .

NCC will pay CenterState a termination fee equal to $31.8 million in the event (i) the Merger Agreement is terminated by CenterState because NCC breaches its non-solicitation obligations or NCC’s board of directors breaches its obligations with respect to giving notice of or making a recommendation in connection with the NCC stockholder meeting, or (ii) NCC receives an acquisition proposal and the Merger Agreement is terminated because the required NCC stockholder approval is not obtained or by CenterState because of NCC’s material breach of representations, warranties or covenants and NCC enters into an acquisition proposal within 12 months of such termination. CenterState will pay NCC a reverse termination fee equal to $31.8 million if the Merger Agreement is terminated by NCC because CenterState’s board of directors breaches its obligations with respect to giving notice of or making a recommendation in connection with the CenterState shareholder meeting.

The foregoing summary of the Merger Agreement is not complete and is qualified in its entirety by reference to the full text of the Merger Agreement and certain exhibits attached thereto, a copy of which is attached hereto as Exhibit 2.1 and incorporated by reference herein.

This Current Report contains “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. In general, forward-looking statements usually use words such as “may,” “believe,” “expect,” “anticipate,” “intend,” “will,” “should,” “plan,” “estimate,” “predict,” “continue” and “potential” or the negative of these terms or other comparable terminology, including statements related to the expected timing of the closing of the Merger, the expected returns and other benefits of the Merger to shareholders, expected improvement in operating efficiency resulting from the Merger, estimated expense reductions resulting from the transactions and the timing of achievement of such reductions, the impact on and timing of

the recovery of the impact on tangible book value, and the effect of the Merger on CenterState’s capital ratios. Forward-looking statements represe nt management’s beliefs, based upon information available at the time the statements are made, with regard to the matters addressed; they are not guarantees of future performance. Forward-looking statements are subject to numerous assumptions, risks and uncertainties that change over time and could cause actual results or financial condition to differ materially from those expressed in or implied by such statements .

Factors that could cause or contribute to such differences include, but are not limited to (1) the risk that the cost savings and any revenue synergies from the Merger may not be realized or take longer than anticipated to be realized, (2) disruption from the Merger with customer, supplier, employee or other business partner relationships, (3) the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement, (4) the risk of successful integration of NCC’s businesses into CenterState, (5) the failure to obtain the necessary approvals by the stockholders of NCC with respect to the Merger or the shareholders of CenterState with respect to the issuance of CenterState common stock in connection with the Merger, (6) the amount of the costs, fees, expenses and charges related to the Merger, (7) the ability by CenterState to obtain required governmental approvals of the Merger, (8) reputational risk and the reaction of each of the companies’ customers, suppliers, employees or other business partners to the Merger, (9) the failure of the closing conditions in the Merger Agreement to be satisfied, or any unexpected delay in closing the Merger, (10) the risk that the integration of NCC’s operations into the operations of CenterState will be materially delayed or will be more costly or difficult than expected, (11) the possibility that the Merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events, (12) the dilution caused by CenterState’s issuance of additional shares of its common stock in the Merger, and (13) general competitive, economic, political and market conditions. Additional factors which could affect the forward looking statements can be found in the cautionary language included under the headings “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Risk Factors” in CenterState’s Annual Report on Form 10-K for the year ended December 31, 2017, NCC’s Annual Report on Form 10-K for the year ended December 31, 2017, and other documents subsequently filed by CenterState and NCC with the SEC. Consequently, no forward-looking statement can be guaranteed. CenterState and NCC do not undertake any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. For any forward-looking statements made in this Current Report on Form 8-K, the exhibits hereto or any related documents, CenterState and NCC claim protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

Section 2.02. Stock-Based Awards .

(a) NCC Stock Options . Each valid option to purchase shares of NCC Common Stock pursuant to the NCC Equity Plans (each an “ NCC Stock Option ”), outstanding and unexercised immediately prior to the Effective Time, shall, by virtue of the Merger, be assumed by CenterState, and automatically and without any action on the part of the holder thereof, be converted into an option to purchase that number of shares of CenterState Common Stock as shall equal the product obtained by multiplying the Exchange Ratio by that number of shares of NCC Common Stock which such NCC Stock Option entitled the holder thereof to purchase (rounded to the nearest whole share), and at an exercise price equal to the quotient obtained by dividing the exercise price per share of the NCC Stock Option by the Exchange Ratio (rounded to the nearest cent); provided, however , that in the event that the Merger Consideration is modified as a result of the application of Section 2.09 , Section 7.01(i) or otherwise, then the Exchange Ratio shall be appropriately adjusted in order to reflect the impact of such modification to the Merger Consideration. Notwithstanding the foregoing, the method of adjusting each NCC Stock Option that is intended to be an “incentive stock option” (as defined in Section 422 of the Code) shall comply with the requirements of Section 424 of the Code and the regulations promulgated thereunder, and the method of adjusting all other NCC Stock Options shall comply with Section 409A of the Code and the regulations promulgated thereunder, so as not to constitute a modification of such NCC Stock Option that would cause such NCC Stock Option to violate Section 409A of the Code. Except with respect to the adjustment described above, each NCC Stock Option shall remain in effect in accordance with its terms and conditions. Where the context so requires, all references to NCC (or an Affiliate or a predecessor of NCC) in the assumed NCC Equity Plans and the applicable award agreements shall be deemed to be references to CenterState and its Subsidiaries, as applicable, and all references to the NCC board of directors (or the Compensation Committee thereof) shall be deemed to be references to the CenterState board of directors (or the Compensation Committee thereof).

Each outstanding and unexercised warrant to purchase NCC Common Stock immediately prior to the Effective Time (each, an “ NCC Warrant ”) shall, by virtue of the Merger, be assumed by CenterState, and automatically and without any action on the part of the holder thereof, cease to represent a right to purchase shares of NCC Common Stock and shall be converted into a right to purchase that number of shares of CenterState Common Stock as shall equal the product obtained by multiplying the Exchange Ratio by that number of shares of NCC Common Stock which such NCC Warrant entitled the holder thereof to purchase (rounded to the nearest whole share), and at an exercise price equal to the quotient obtained by dividing the exercise price per share of the NCC Warrant by the Exchange Ratio (rounded to the nearest cent); provided, however , that in the event that the Merger Consideration is modified as a result of the application of Section 2.09 , Section 7.01(i) or otherwise, then the Exchange Ratio shall be appropriately adjusted in order to reflect the impact of such modification to the Merger Consideration. Except with respect to the adjustment described above, each NCC Warrant shall remain in effect in accordance with its terms and conditions. Where the context so requires, all references to NCC (or an Affiliate or a predecessor of NCC) in the assumed agreements representing the NCC Warrants shall be deemed to be references to CenterState and its Subsidiaries, as applicable, and all references to the NCC board of directors (or the Compensation Committee thereof) shall be deemed to be references to the CenterState board of directors (or the Compensation Committee thereof).

Such shares, to the extent that they become NCC Deferred Shares , shall be entitled to receive the Merger Consideration in accordance with Section 2.02(d) , and to the extent they are instead issued as shares of NCC Common Stock and do not become NCC Deferred Shares , shall be included in the NCC Common Stock issued and outstanding immediately prior to the Effective Time and shall be entitled to receive the Merger Consideration in accordance with Section 2.01(c) . In the event that the Effective Time takes place prior to the certification described above, such 2015 Performance Share Awards shall be treated in a manner identical to the 2016-2018 Performance Share Awards , as described below.

(ii) 2016-2018 Performance Share Awards .

As promptly as practicable after the Effective Time but in no event later than five (5) Business Days after the Closing Date, and provided that NCC has delivered, or caused to be delivered, to the Exchange Agent all information that is reasonably necessary for the Exchange Agent to perform its obligations as specified herein, the Exchange Agent shall mail or otherwise cause to be delivered to each Holder appropriate and customary transmittal materials, in a form reasonably satisfactory to CenterState and NCC, which shall specify that delivery shall be effected, and risk of loss and title to the Certificates or Book-Entry Shares shall pass, only upon delivery of the Certificates or Book-Entry Shares to the Exchange Agent, as well as instructions for use in effecting the surrender of the Certificates or Book-Entry Shares in exchange for the Merger Consideration (and cash in lieu of fractional shares as specified in Section 2.04 ) (the “ Letter of Transmittal ”).

Section 2.07. Deposit of Merger Consideration .

(a) Prior to the Effective Time, CenterState shall deposit, or shall cause to be deposited, with the Exchange Agent (i) the number of shares of CenterState Common Stock issuable pursuant to Section 2.01(c) , Section 2.02(c)(ii) and Section 2.02(d) in book-entry form equal to the aggregate CenterState

Common Stock portion of the Merger Consideration (excluding any fractional shares), and ( ii ) cash in an amount sufficient to pay, to the extent then determinable, any cash payable in lieu of fractional shares pursuant to Section 2.04 (collectively, the “ Exchange Fund ”).

(b) Any portion of the Exchange Fund that remains unclaimed by the stockholders of NCC for one (1) year after the Effective Time (as well as any interest or proceeds from any investment thereof) shall be delivered by the Exchange Agent to CenterState. Any stockholders of NCC who have not theretofore complied with this Section 2.07 and Section 2.08(a) shall thereafter look only to CenterState for the Merger Consideration, 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 shall have become entitled to pursuant to Section 2.08(b) deliverable in respect of each share of NCC Common Stock such stockholder held as of immediately prior to the Effective Time, as determined pursuant to this Agreement, in each case without any interest thereon. If outstanding Certificates or Book-Entry Shares for shares of NCC Common Stock are not surrendered or the payment for them is not claimed prior to the date on which such shares of CenterState Common Stock or cash would otherwise escheat to or become the property of any governmental unit or agency, the unclaimed items shall, to the extent permitted by the law of abandoned property and any other applicable Law, become the property of CenterState (and to the extent not in its possession shall be delivered to it), free and clear of all claims or interest of any Person previously entitled to such property. Neither the Exchange Agent nor any Party shall be liable to any Holder represented by any Certificate or Book-Entry Share for any Merger Consideration (or any dividends or distributions with respect thereto) paid to a public official pursuant to applicable abandoned property, escheat or similar Laws. CenterState and the Exchange Agent shall be entitled to rely upon the stock transfer books of NCC to establish the identity of those Persons entitled to receive the Merger Consideration specified in this Agreement, which books shall be conclusive with respect thereto. In the event of a dispute with respect to ownership of any shares of NCC Common Stock represented by any Certificate or Book-Entry Share, CenterState and the Exchange Agent shall be entitled to tender to the custody of any court of competent jurisdiction any Merger Consideration represented by such Certificate or Book-Entry Share and file legal proceedings interpleading all parties to such dispute, and will thereafter be relieved with respect to any claims thereto.

Section 2.08. Delivery of Merger Consideration .

(a) Upon surrender to the Exchange Agent of its Certificate(s) or Book-Entry Share(s), accompanied by a properly completed Letter of Transmittal, a Holder will be entitled to receive in exchange therefor, as applicable, (i) book-entry shares representing that number of whole shares of CenterState Common Stock to which such Holder shall have become entitled pursuant to Section 2.01(c) (excluding any fractional share) and (ii) cash in an amount equal to (A) any cash in lieu of fractional shares of CenterState Common Stock which such Holder shall have become entitled pursuant to Section 2.04 , and (B) any dividends or distributions to which such Holder shall have become entitled pursuant to Section 2.08(b) . CenterState shall direct the Exchange Agent to provide to each such Holder of NCC Common Stock (x) the applicable Merger Consideration, (y) any cash in lieu of fractional shares of CenterState Common Stock pursuant to Section 2.04 , and (z) and any dividends or distributions to which such Holder shall have become entitled to pursuant to Section 2.08(b) promptly, which shall be no later than five (5) Business Days upon receipt of a Holder’s Certificates or Book-Entry Shares and a completed Letter of Transmittal. The Exchange Agent and CenterState, as the case may be, shall not be obligated to deliver cash and/or shares of CenterState Common Stock to a Holder to which such Holder would otherwise be entitled as a result of the Merger until such Holder surrenders the Certificates or Book-Entry Shares representing the shares of NCC Common Stock for exchange as provided in this Article II , or, an appropriate affidavit of loss and indemnity agreement and/or a bond in such amount as may be reasonably required in each case by CenterState or the Exchange Agent. In the event of a transfer of ownership of a Certificate representing NCC Common Stock that is not registered in the stock transfer records of NCC, the proper amount of the Merger Consideration shall be paid or issued in exchange therefor to a Person

other than the Person in whose name the Certificate so surrendered is registered if the Certificate formerly representing such NCC 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.

(b) All shares of CenterState Common Stock to be issued pursuant to the Merger shall be deemed issued and outstanding as of the Effective Time and if ever a dividend or other distribution is declared by CenterState in respect of the CenterState Common Stock, the record date for which is at or after the Effective Time, that declaration shall include dividends or other distributions in respect of all shares of CenterState Common Stock issuable pursuant to this Agreement. No dividends or other distributions in respect of the CenterState Common Stock shall be paid to any holder of any unsurrendered Certificate or Book-Entry Share until such Certificate or Book-Entry Share is surrendered for exchange in accordance with this Article II . Subject to the effect of applicable Laws, following surrender of any such Certificate or Book-Entry Share, there shall be issued and/or paid to the holder of the certificates representing whole shares of CenterState Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the dividends or other distributions with a record date after the Effective Time theretofore payable with respect to such whole shares of CenterState Common Stock and not paid and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such whole shares of CenterState Common Stock with a record date after the Effective Time but with a payment date subsequent to surrender.

(c) CenterState (through the Exchange Agent, if applicable) shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement to any Holder such amounts as CenterState is required to deduct and withhold under applicable Law. Any amounts so deducted and withheld shall be remitted to the appropriate Governmental Authority and upon such remittance shall be treated for all purposes of this Agreement as having been paid to the Holder in respect of which such deduction and withholding was made by CenterState or the Exchange Agent, as applicable.

Section 2.09. Anti-Dilution Provisions . If the number of shares of CenterState Common Stock or NCC Common Stock issued and outstanding prior to the Effective Time shall be increased or decreased, or changed into or exchanged for a different number of kind of shares or securities, in any such case as a result of a stock split, reverse stock split, stock combination, stock dividend, recapitalization, reclassification, reorganization or similar transaction, or there shall be any extraordinary dividend or distribution with respect to such stock, and the record date therefor shall be prior to the Effective Time, an appropriate and proportionate adjustment shall be made to the Merger Consideration to give Holders of NCC Common Stock the same economic effects as contemplated by this Agreement prior to such event.

Porter Keadle Moore, LLC has not resigned (or informed NCC that it intends to resign) or been dismissed as independent public accountants of NCC as a result of or in connection with any disagreements with NCC on a matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure.

(b) Except as would not reasonably be likely to have, either individually or in the aggregate, a Material Adverse Effect on NCC , neither NCC nor any of its Subsidiaries has any liability of any nature whatsoever (whether absolute, accrued, contingent or otherwise and whether due or to become due), except, (i) for those liabilities that are reflected or reserved against on the consolidated balance sheet of NCC included in its Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2018 ( including any notes thereto), (ii) for liabilities incurred in the Ordinary Course of Business consistent with past practice since September 30, 2018 , (iii) as set forth in NCC Disclosure Schedule Section 3.07(b) or (iv) in connection with this Agreement and the transactions contemplated hereby .

reporting (copies of such items in subsections (A ) and (B ), to the extent applicable, have previously been made available by NCC to CenterState).

(d) Since January 1, 2016, (i) neither NCC nor any of its Subsidiaries, nor, to the knowledge of NCC, any director, executive officer, auditor, accountant or representative of NCC or any of its Subsidiaries, has received or otherwise had or obtained knowledge of any material complaint, allegation, assertion or claim, whether written or, to the knowledge of NCC, oral, regarding the accounting or auditing practices, procedures, methodologies or methods (including with respect to loan loss reserves, write-downs, charge-offs and accruals) of NCC or any of its Subsidiaries or their respective internal accounting controls, including any material complaint, allegation, assertion or written claim that NCC or any of its Subsidiaries has engaged in questionable accounting or auditing practices, and (ii) no attorney representing NCC or any of its Subsidiaries, whether or not employed by NCC or any of its Subsidiaries, has reported evidence of a material violation of securities laws, breach of fiduciary duty or similar violation by NCC or any of its officers, directors, employees or agents to the board of directors of NCC or any committee thereof or to the knowledge of NCC, to any director or officer of NCC.

(f) Subject to Section 7.01 and Section 7.02 , if, following an Intervening Event, the board of directors of NCC, after receiving the advice of its outside counsel, and, with respect to financial matters, its financial advisors, determines in good faith that it would be more likely than not to result in a violation of its fiduciary duties under applicable Law to continue to recommend this Agreement, then in submitting this Agreement, such board of directors may submit this Agreement to its shareholders without recommendation (although the resolutions approving this Agreement as of the date of this Agreement may not be rescinded or amended), in which event the board of directors may communicate the basis for its lack of a recommendation to its shareholders in the Proxy Statement-Prospectus or an appropriate amendment or

supplement thereto to the extent required by Law; provided that the NCC board of directors may not take any actions under this sentence unless (i) it gives CenterState at least five (5) Business Days’ prior written notice of its intention to take such action and a reasonable description of the event or circumstances giving rise to its determination to take such action, and (ii) at the end of such notice period, the NCC board of directors takes into account any amendment or modification to this Agreement proposed by CenterState and after receiving the advice of its outside counsel, and, with respect to financial matters, its financial advisor, determines in good faith that it would nevertheless be more likely than not to result in a violation of its fiduciary duties under applicable Law to continue to recommend this Agreement.

(g) Nothing contained in this Section 5.09 or elsewhere in this Agreement shall prohibit NCC or the board of directors of NCC from complying with Rule 14e-2(a), Item 1012(a) of Regulation M-A or Rule 14d-9 promulgated under the Exchange Act or other applicable securities laws; provided, however , that any such disclosure relating to an NCC Acquisition Proposal (other than a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9 under the Exchange Act) shall be deemed a change in the NCC Recommendation unless the board of directors of NCC reaffirms the NCC Recommendation in such disclosure.

Section 5.10. Indemnification .

(a) From and after the Effective Time, and in any event subject to the provisions of Section 5.10(c)(iv) , the Surviving Entity shall indemnify, defend and hold harmless the present and former directors, officers and employees of NCC, NBC and their respective Subsidiaries (the “ Indemnified Parties ”), against all costs or expenses (including reasonable attorney’s fees), judgments, fines, losses, claims, damages, or liabilities or amounts that are paid in settlement (which settlement shall require the prior written consent of CenterState, which consent shall not be unreasonably withheld, conditioned or delayed) incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative arising out of actions or omissions of such persons in the course of performing their duties for or at the request of NCC, NBC or their respective Subsidiaries occurring at or before the Effective Time (including the Merger and the other transactions contemplated by this Agreement) (each a “ Claim ”), regardless of whether such Claim is asserted or claimed before, or after, the Effective Time, to the fullest extent as such persons have the right to be indemnified pursuant to the NCC Certificate or NCC Bylaws or similar governing documents of NBC in effect on the date of this Agreement and to the fullest extent permitted by applicable Delaware Law. The Surviving Entity shall pay such expenses to each Indemnified Party to the fullest extent permitted by the provisions of Delaware Law and the NCC Certificate and NCC Bylaws or similar governing documents of NBC.

(b) In connection with the indemnification provided pursuant to this Section 5.10 , the Surviving Entity and/or Surviving Bank will advance expenses, promptly after statements therefor are received, to each Indemnified Party, to the fullest extent required or permitted by the NCC Certificate, the NCC Bylaws and the articles of association and bylaws of NBC in effect on the date of this Agreement and to the fullest extent permitted by applicable Law (provided the individual to whom expenses are advanced provides an undertaking to repay such advance if it is ultimately determined that such individual is not entitled to indemnification), including the payment of the fees and expenses of one counsel with respect to a matter, and one local counsel in each applicable jurisdiction, if necessary or appropriate, selected by such Indemnified Party or multiple Indemnified Parties (and, in each case, reasonably acceptable to CenterState), it being understood that they collectively shall only be entitled to one counsel and one local counsel in each applicable jurisdiction where necessary or appropriate (unless a conflict shall exist between them in which case they may retain separate counsel).

(c) Any Indemnified Party wishing to claim indemnification under this Section 5.10 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 5.10 , unless, and only to the extent that, CenterState is materially prejudiced in the defense of such Claim as a consequence. In the event of any such Claim (whether asserted or claimed prior to, at or after the Effective Time), (i) CenterState shall have the right to assume the defense thereof and CenterState shall not be liable to such Indemnified Parties for any legal expenses or other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof except that if CenterState elects not to assume such defense, the Indemnified Parties may retain counsel reasonably satisfactory to them, and CenterState shall pay the reasonable fees and expenses of such counsel for the Indemnified Parties (provided that CenterState shall only be obligated to pay the reasonable fees and expenses of one such counsel), (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 (iv) CenterState shall have no obligation hereunder to any Indemnified Party if such indemnification would be in violation of any applicable federal or state banking laws or regulations, or in the event that a federal or state banking agency or a court of competent jurisdiction shall determine that indemnification of an Indemnified Party in the manner contemplated hereby is prohibited by applicable Laws, whether or not related to banking laws.

(d) For a period of six (6) years following the Effective Time, the Surviving Entity will maintain director’s and officer’s liability insurance (“ D&O Insurance ”) that serves to reimburse the present and former officers and directors of NCC or NBC and their respective Subsidiaries (determined as of immediately prior to the Effective Time) with respect to claims against such Indemnified Parties arising from facts or events occurring at or before the Effective Time (including the Merger and other transactions contemplated by this Agreement), which insurance will contain at least the same coverage and amounts, and contain terms and conditions no less advantageous to the Indemnified Party, as that coverage currently provided by NCC; provided that , if the Surviving Entity is unable to maintain or obtain the insurance called for by this Section 5.10 , the Surviving Entity will provide as much comparable insurance as is reasonably available (subject to the limitations described below in this Section 5.10(d) ); and provided, further, that officers and directors of NCC or NBC may be required to make application and provide customary representations and warranties to the carrier of the D&O Insurance for the purpose of obtaining such insurance. In no event shall the Surviving Entity be required to expend for such tail insurance a premium amount in excess of $1,500,000 in the aggregate (the “ Maximum D&O Tail Premium ”). If the cost of such tail insurance exceeds the Maximum D&O Tail Premium, the Surviving Entity 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. For the avoidance of doubt, the Surviving Entity shall not be required to purchase stand-alone coverage for cyber liability or fidelity bonds.

(e) This Section 5.10 shall survive the Effective Time, is intended to benefit each Indemnified Party (each of whom shall be entitled to enforce this Section 5.10 against the Surviving Entity), and shall be binding on all successors and assigns of the Surviving Entity. This Section 5.10 shall not be amended, altered or repealed after the Effective Time without the prior written consent of the affected Indemnified Party.

(f) If the Surviving Entity 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 the Surviving Entity and its Subsidiaries shall assume the obligations set forth in this Section 5.10 .

Section 5.11. Employees; Benefit Plans .

(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 employees of NCC or any of its Affiliates 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, including any such plan that is closed or frozen with respect to new employees of CenterState. CenterState shall give the Covered Employees full credit for their prior service with NCC and any of its Affiliates (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, severance plans and similar arrangements maintained by CenterState.

(b) With respect to any employee benefit plan of the Surviving Entity 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, the Surviving Entity or its applicable Subsidiary shall use its commercially reasonable efforts to (i) cause any pre-existing condition limitations or eligibility waiting periods under such Surviving Entity or Subsidiary plan to be waived with respect to such Covered Employee and his or her covered dependents to the extent such condition was or would have been covered under the NCC Benefit Plan in which such Covered Employee participated immediately prior to the Effective Time, and (ii) recognize any health, dental, vision or other welfare expenses incurred by such Covered Employee and his or her covered dependents in the year that includes the Closing Date (or, if later, the year in which such Covered Employee is first eligible to participate) for purposes of any applicable copayment, deductibles and annual out-of-pocket expense requirements under any such health, dental, vision or other welfare plan. Neither CenterState nor any of its Subsidiaries shall terminate the existing coverage of any Covered Employee or his or her dependents under any of the NCC or Affiliate health, dental, vision or other welfare plans, programs or benefits prior to the time such Covered Employees and their dependents become eligible to participate in the health, dental or other welfare plans, programs and benefits common to all employees of CenterState or any CenterState Subsidiary and their dependents.

(c) Prior to the Effective Time and subject to the consummation of the transactions contemplated by this Agreement, NCC shall take, and shall cause each of its Subsidiaries to take, all actions requested no later than ten (10) days prior to the Closing by CenterState that may be necessary or appropriate to (i) cause one or more NCC Benefits Plans to terminate as of the Effective Time, or as of the date immediately preceding the date that includes the Effective Time, (ii) cause benefit accruals and entitlements under any NCC Benefit Plan to cease as of the Effective Time, or as of the date immediately preceding that date that includes the Effective Time, (iii) cause the continuation on and after the Effective Time of any contract, arrangement or insurance policy relating to any NCC Benefit Plan for such period as may be requested by CenterState, or (iv) facilitate the merger of any NCC Benefit Plan into any employee benefit plan maintained by CenterState or a CenterState Subsidiary; provided that NCC shall not be required to take any action that would result in the violation by NCC of any contract with a third party. All resolutions, notices, or other documents issued, adopted or executed in connection with the implementation of this Section 5.11(c) shall be subject to CenterState’s reasonable prior review, which shall not be unreasonably withheld, conditioned or delayed. If CenterState requires NCC to terminate a medical plan having a flexible spending arrangement (“ FSA ”) under Section 125 of the Code, NCC and each of its Subsidiaries may continue its FSA through the Effective Time.

(d) Nothing in this Section 5.11 shall be construed to (i) limit the right of CenterState or any of its Subsidiaries (including, following the Closing Date, NCC or any of its Subsidiaries) to amend or terminate any NCC Benefit Plan or other employee benefit plan, to the extent such amendment or termination is permitted by the terms of the applicable plan; (ii) establish, amend, or modify any NCC Benefit Plan or CenterState Benefit Plan or any other benefit or employment plan, program, agreement or arrangement; or (iii) require CenterState or any of its Subsidiaries (including, following the Closing Date, NCC and any of its Subsidiaries) to retain the employment of any particular Covered Employee for any fixed period of time following the Closing Date, and the continued retention (or termination) by 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) If, within the period ending on the later of (i) nine (9) months after the Effective Time or (ii) forty-five (45) days after the completion of the Informational Systems Conversion, unless otherwise addressed in an employment agreement entered into with CenterState or CenterState Bank or an employment, change in control or severance agreement set forth in NCC Disclosure Schedule Section 3.11(a) , any Covered Employee who is terminated by CenterState or its Subsidiaries other than “for cause” (as defined under the policies of CenterState and/or its Subsidiaries) or resigns because he or she was offered a position with a material reduction in rate of base pay or that is outside a 50-mile radius of the current address of his or her primary work location at NCC or any of its Subsidiaries, then CenterState shall, subject to such Covered Employee’s execution of appropriate releases, pay severance to such Covered Employee in an amount equal to two (2) weeks of base salary for each twelve (12) months of such Covered Employee’s prior employment with NCC, NBC or any applicable Subsidiary; provided , however , that in no event will the total amount of severance for any single Covered Employee be less than four (4) weeks of such base salary nor greater than twenty-six (26) weeks of such base salary. Any severance to which a Covered Employee may be entitled in connection with a termination occurring more than nine (9) months after the Effective Time will be as set forth in the severance policies of CenterState and its Subsidiaries as then in effect.

Prior to the Effective Time, if CenterState requests NCC’s assistance with respect to implementing new or replacement employment related agreements for one or more employees of NCC or any of its Subsidiaries in connection with the Merger, NCC agrees to (and shall cause its Subsidiaries to) cooperate in good faith to facilitate and assist with respect to implementing any such new or replacement employment related agreements.

(h) CenterState shall take all commercially reasonable actions necessary, including any needed plan or policy amendments, to cause the trustee of the CenterState Banks, Inc. Employee Savings Trust, if requested to do so by a Covered Employee, to accept a direct “rollover” in cash of all or a portion of such employee’s distribution from NCC’s (or its Affiliate’s) qualified 401(k) savings plan (collectively, the “ NCC 401(k) Plan ”) (provided that the CenterState Banks, Inc. Employee Savings Trust shall only accept

cash and not in kind rollovers). In the case of a Covered Employee with an outstanding loan(s) under the NCC 401(k) Plan, CenterState shall use commercially reasonable efforts to permit the Covered Employee to rollover such outstanding loan balance(s) to the CenterState Banks, Inc. Employee Savings Trust (subject to the requirements and limitations of the applicable provisions of the Code); provided, however , that the Covered Employee may transfer such loan(s) only if such Covered Employee elects to rollover his or her entire account balance under the NCC 401(k) Plan.

No supplement or amendment to the NCC Disclosure Schedule or CenterState Disclosure Schedule, as applicable, or provision of information relating to the subject matter of the NCC Disclosure Schedule or CenterState Disclosure Schedule, as applicable, after the date of this Agreement shall operate to cure any breach of a representation or warranty made herein or have any effect for the purpose of determining satisfaction of or compliance by NCC or CenterState with the respective covenants and agreements of such parties set forth herein.

Stockholder 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 stockholder of NCC, to approve or adopt the Merger Agreement unless this Agreement shall have been terminated in accordance with its terms.

2. No Transfers .

Any transfer or other disposition in violation of the terms of this Section 2 shall be null and void.

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

(a)

Stockholder 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 Stockholder, and assuming the due authorization, execution and delivery by CenterState, constitutes the valid and legally binding obligation of Stockholder enforceable against Stockholder 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 Stockholder does not, and the performance by Stockholder of his, her or its obligations hereunder and the consummation by Stockholder 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 Stockholder is a party or by which Stockholder is bound, or any statute, rule or regulation to which Stockholder is subject or, in the event that Stockholder is a corporation, limited liability company, partnership, trust or other entity, any charter, bylaw or other organizational document of Stockholder.

(d)

Stockholder is the direct or joint owner of the Shares. Stockholder does not have sole or shared voting or dispositive power over any shares of capital stock of NCC other than the Shares or any

other securities convertible into or exercisable or exchangeable for such capital stock, other than any NCC Equity Awards or NCC Warrants. Stockholder has the right to vote the Shares, and none of the Shares are 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 Stockholder exercises control in a fiduciary capacity for any other person or entity that is not an Affiliate of Stockholder, and no representation by Stockholder is made with respect thereto.

4. No Solicitation . From and after the date hereof until the termination of this Agreement pursuant to Section 6 hereof, Stockholder, in his, her or its capacity as a stockholder of NCC, shall not, nor shall Stockholder in such capacity authorize any stockholder, member, partner, officer, director, advisor or representative of Stockholder or any of his, her or its Affiliates to (and, to the extent applicable to Stockholder, such Stockholder 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 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 NCC 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 reasonably be expected to 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 stockholders’ vote or action by consent of NCC’s stockholders with respect to an Acquisition Proposal, except in the cases of clauses (b) through (e), inclusive, of this Section 4 to the extent that at such time NCC is permitted to take such actions pursuant to Section 5.09 of the Merger Agreement.

5. Specific Performance; Remedies; Attorneys’ Fees . Stockholder acknowledges that it is a condition to the willingness of CenterState to enter into the Merger Agreement that Stockholder execute and deliver this Agreement and that it will be impossible to measure in money the damage to CenterState if Stockholder 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. Accordingly, Stockholder agrees that injunctive relief or other equitable relief 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, after notice to Stockholder, CenterState shall have the right to inform any third party that CenterState reasonably believes to be, or to be contemplating, participating with Stockholder or receiving from Stockholder 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 third party with Stockholder in activities in violation of Stockholder’s agreement with CenterState set forth in this Agreement may give rise to claims by CenterState against such third party. All expenses incurred in connection with this Agreement and the transactions contemplated by this Agreement shall be paid by the party incurring such expenses.

6. Term of Agreement; Termination . The term of this Agreement shall commence on the date hereof. This Agreement may be terminated at any time prior to consummation of the transactions contemplated by the Merger Agreement by the written consent of the parties hereto, and this Agreement shall be automatically terminated upon the earlier to occur of: (a) termination of the Merger Agreement, (b) the consummation of the Merger, or (c) three (3) years from the date hereof; provided , however , that the transfer restrictions in Section 2 hereof shall be automatically terminated upon the receipt of the Requisite NCC Stockholder Approval. 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.

7. 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.

8. 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.

9. Capacity as Stockholder . This Agreement shall apply to Stockholder solely in his, her or its capacity as a stockholder of NCC, and it shall not apply in any manner to Stockholder in any capacity as a director, officer or employee of NCC or in any other capacity.

2.5 Officers . Effective as of the Effective Time, the officers of the Surviving Corporation shall be as set forth on Exhibit A to this Plan of Merger.

SECTION 3

MANNER OF CONVERTING SHARES

Each share of CenterState common stock that is issued and outstanding immediately prior to the Effective Time shall remain outstanding following the Effective Time and shall be unchanged by the Merger.

Each share of common stock of NCC owned directly by CenterState, NCC or any of their respective subsidiaries (other than shares in trust accounts, managed accounts and the like for the benefit of customers or shares held as collateral for outstanding debt previously contracted) immediately prior to the Effective Time shall be cancelled and retired at the Effective Time without any conversion thereof, and no payment shall be made with respect thereto.

Each share of common stock of NCC issued and outstanding immediately prior to the Effective Time (other than shares described in the immediately preceding paragraph), shall be converted into the right to receive 1.65 shares (the “ Exchange Ratio ”) of CenterState common stock (the “ Merger Consideration ”) and cash in lieu of any fractional shares. CenterState shall pay or cause to be paid to each holder of a fractional share of CenterState common stock, rounded to the nearest one-hundredth of a share, an amount of cash (without interest and rounded to the nearest whole cent) determined by multiplying the fractional share interest in CenterState common stock to which such holder would otherwise be entitled by the average closing price of CenterState common stock as reported on the NASDAQ Stock Market for the twenty (20) consecutive trading days ending on the trading day immediately prior to the later of (i) the day on which the last required regulatory approval for consummation of the Merger is obtained without regard to any requisite waiting period, or (ii) the date on which NCC stockholders approve the Merger (the “ CenterState Average Stock Price ”).

If the number of shares of CenterState common stock or NCC 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 CenterState and NCC.

SECTION 4

Stock-Based Awards

Each valid option to purchase shares of NCC common stock pursuant to the NCC equity plans (each an “ NCC Stock Option ”), outstanding and unexercised immediately prior to the Effective Time, shall, by virtue of the Merger, be assumed by CenterState, and automatically and without any action on the part of the holder thereof, be converted into an option to purchase that number of shares of CenterState common stock as shall equal the product obtained by multiplying the Exchange Ratio by that number of shares of NCC common stock which such NCC Stock Option entitled the holder thereof to purchase (rounded to the nearest whole share), and at an exercise price equal to the quotient obtained by dividing the exercise price per share of the NCC Stock Option by the Exchange Ratio (rounded to the nearest cent); provided, however , that in the event that the Merger Consideration is modified as a result of the application of the last paragraph of Section 3 or otherwise, then the Exchange Ratio shall be appropriately adjusted in order to reflect the impact of such modification to the Merger Consideration..

Each outstanding and unexercised warrant to purchase NCC common stock immediately prior to the Effective Time (each, an “ NCC Warrant ”) shall, by virtue of the Merger, be assumed by CenterState, and automatically and without any action on the part of the holder thereof, cease to represent a right to purchase shares of NCC common stock and shall be converted into a right to purchase that number of shares of CenterState common stock as shall equal the product obtained by multiplying the Exchange Ratio by that number of shares of NCC common stock which such NCC Warrant entitled the holder thereof to purchase (rounded to the nearest whole share), and at an exercise price equal to the quotient obtained by dividing the exercise price per share of the NCC Warrant by the Exchange Ratio (rounded to the nearest cent); provided, however , that in the event that the Merger Consideration is modified as a result of the application of the last paragraph of Section 3 or otherwise, then the Exchange Ratio shall be appropriately adjusted in order to reflect the impact of such modification to the Merger Consideration.

At the Effective Time, the deferrals of NCC common stock representing equity awards and director fees credited to participant accounts under the National Commerce Corporation Deferral of Compensation Plan (the “ NCC Deferred Shares ”) shall be converted into the right to receive, within ten (10) days following the Effective Time, the Merger Consideration in respect of each such NCC Deferred Share, subject to applicable tax withholding.

All outstanding performance share awards with respect to shares of NCC common stock for the four-year performance period ending on December 31, 2018 (the “ 2015 Performance Share Awards ”) shall, in accordance with the applicable NCC equity plan and award agreements, vest and be issued by NCC as soon as reasonably practicable after the following dates: (A) for time-based awards, December 31, 2018, and (B) for performance-based awards, the date of certification by the Compensation Committee of the NCC board of directors and confirmation by NCC’s independent public accountants, of the extent to which the performance criteria underlying such awards have been achieved, in accordance with the applicable award agreements, and in no event later than March 15, 2019. Such shares, to the extent that they become NCC Deferred Shares, shall be entitled to receive the Merger Consideration in accordance with the preceding paragraph, and to the extent they are instead issued as shares of NCC common stock and do not become NCC Deferred Shares, shall be included in the NCC common stock issued and outstanding immediately prior to the Effective Time and shall be entitled to receive the Merger Consideration in accordance with Section 3. In the event that the Effective Time takes place prior to the certification described above, such 2015 Performance Share Awards shall be treated in a manner identical to the 2016-2018 Performance Share Awards, as described below.

Immediately prior to the Effective Time, the outstanding performance share awards with respect to shares of NCC common stock for the four-year performance periods ending on December 31, 2019, 2020 and 2021, all of which are to be measured over a performance period that will not be completed prior to the Effective Time (the “ 2016-2018 Performance Share Awards ”), shall vest as specified in the applicable award agreements (it being understood that the determination of the number of performance shares earned under the applicable award agreements, and the extent to which the performance goals have been achieved for the partial performance period, shall be conclusively determined, in good faith, by the Compensation Committee of the NCC board of directors, in accordance with the change in control provisions in the applicable NCC equity plans and award agreements, as soon as reasonably practicable prior to the Closing, which determination shall be final and binding on the Parties). Each of the 2016-2018 Performance Share Awards shall be cancelled at the Effective Time in exchange for the right to receive, within ten (10) days following the Effective Time, the Merger Consideration in respect of each share of NCC common stock underlying such 2016-2018 Performance Share Awards as determined pursuant to this Section, subject to applicable tax withholding.

NON-COMPETITION AND NON-DISCLOSURE AGREEMENT

This Non-Competition and Non-Disclosure Agreement (the “ Agreement ”), is entered into as of the 23 ^rd day of November, 2018, by and between CenterState Bank Corporation, a Florida corporation (“ CenterState ”), and the undersigned individual (“ Director ”).

RECITALS

WHEREAS , pursuant to that certain Agreement and Plan of Merger dated as of November 23, 2018 (the “ Merger Agreement ”) by and between CenterState and National Commerce Corporation, a Delaware corporation (“ NCC ”), NCC will merge with and into CenterState (the “ Merger ”), as a result of which National Bank of Commerce, a national banking association and wholly-owned subsidiary of NCC (“ NBC ”), will merge with and into CenterState Bank, N.A., a national banking association and wholly-owned subsidiary of CenterState (“ CenterState Bank ”);

WHEREAS , Director is a stockholder of NCC 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 NCC common stock held by Director;

WHEREAS , prior to the date hereof, Director has served as a member of the board of directors of NCC and/or NBC, and, therefore, Director has knowledge of the Confidential Information and Trade Secrets (each as hereinafter defined);

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 NCC and NBC, 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:

1. Restrictive Covenants .

(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 (other than Trade Secrets) for a period of two (2) years from the Effective Time or Trade Secrets for so long as they remain Trade Secrets, 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: (A) 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 (B) use commercially reasonable efforts to obtain assurances that any Confidential Information disclosed will be accorded confidential treatment. If, in the absence of a waiver or protective order, Director is nonetheless, in the opinion of his or her counsel, required to disclose Confidential Information, disclosure may be made only as to that portion of the Confidential Information that counsel advises Director is required to be disclosed. Nothing contained in this Agreement limits the Director’s ability to file a charge or complaint with, communicate with (except with respect to information covered by 17 C.F.R. 240.21F-4(b)(4)(i) or 17 C.F.R. 240.21F-4(b)(4)(ii), which relate to legal representation), or otherwise participate in any investigation or proceeding that may be conducted by (i) the Equal Employment Opportunity Commission (the “ EEOC ”) or the Securities and Exchange Commission (the “ SEC ”) or (ii) any other federal, state or local governmental agency or commission that has jurisdiction over CenterState or any of its subsidiaries or affiliates (the “ Government Agencies ”) if and to the extent that it is not permitted by applicable law to limit the Director’s ability to file such a charge or complaint with, communicate with, or otherwise participate in any investigation or proceeding that may be conducted by such Government Agency; in each such case, including by providing documents or other information, without notice to CenterState or any of its subsidiaries or affiliates. This Agreement does not limit the Director’s right to receive an award for information provided to (1) the SEC or (2) the EEOC or any other Government Agency, if and to the extent that it is not permissible by law to limit the Director’s right to receive an award for information provided to the EEOC or such other Government Agency. In addition, pursuant to the Defend Trade Secrets Act of 2016, the Director understands that an individual may not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that (i) is made (A) in confidence to a federal, state or local government official, either directly or indirectly, or to an attorney; and (B) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. Further, an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the employer's trade secrets to the attorney and use the trade secret information in the court proceeding if the individual (y) files any document containing the trade secret under seal; and (z) does not disclose the trade secret, except pursuant to court order.

(ii) Except as expressly provided on Schedule I to this Agreement, for a period beginning at the Effective Time and ending two (2) years after the Effective Time, Director will not (except on behalf of or with the prior written consent of CenterState), on Director’s own behalf or in the service or on behalf of others, solicit or attempt to solicit any individual or entity that is known by Director to be a customer of CenterState, CenterState Bank, NCC or NBC (each a “ Protected Party ”), including known actively sought prospective customers of NBC as of the Effective Time, for the purpose of providing banking 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 (as hereinafter defined).

(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, recruit or hire, or attempt to solicit, recruit or hire, directly or by assisting others, any individual who is known by Director to be an employee of any Protected Party or to have been

an employee of any Protected Party within one year prior to such activity, whether or not such employee is a full-time employee, whether or not such employment is pursuant to a written agreement, and whether or not such employment is for a determined period or is at will, to cease working for such Protected Party; provided that the foregoing will not prevent the placement of any general solicitation for employment not specifically directed towards employees of any Protected Party or hiring any such person as a result thereof.

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

(ii) “ Confidential Information ” shall mean data and information:

(A) relating to the business of NCC and its subsidiaries, including NBC, or the business of CenterState or its subsidiaries, including CenterState 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 NCC and/or NBC;

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

(D) not generally known to competitors of NCC or CenterState.

Confidential Information shall include Trade Secrets (as hereinafter defined), 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 NCC 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, Georgia, or Alabama where NBC operates a banking office at the Effective Time and each county contiguous to each of such counties.

(iv) “ Trade Secrets ” shall mean information, without regard to form, including technical or nontechnical data, formulas, patterns, compilations, programs, devices, methods, techniques, drawings, processes, 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. Term; Termination . This Agreement may be terminated at any time by the written consent of the parties hereto, and this Agreement shall be automatically terminated upon the earlier of (a) termination of the Merger Agreement, (b) two (2) years following the Effective Time, or (c) upon a Change in Control of CenterState. For the avoidance of doubt, the provisions of Section 1 shall only become operative upon the consummation of the Merger but, in such event, shall survive the consummation of the Merger until the earlier of two (2) years after the Effective Time or a Change in Control of CenterState. Upon termination of this Agreement, no party shall have any further obligations or liabilities hereunder, except that termination of this Agreement will not relieve a breaching party from liability for any breach of any provision of this Agreement occurring prior to the termination of this Agreement. For purposes of this Agreement, a “Change in Control of CenterState” means (a) any person or group of persons within the meaning of §13(d)(3) of the Securities Exchange Act of 1934, as amended, becomes the beneficial owner, directly or indirectly, of 50% or more of the (1) outstanding voting securities of CenterState or CenterState Bank, or (2) the assets of CenterState or CenterState Bank, taken as a whole, or (b) individuals serving on the board of directors of CenterState as of the Effective Time cease for any reason to constitute at least a majority of the board of directors of CenterState (the “ Incumbent Board ”), provided that any person becoming a director subsequent to the Effective Time whose election was approved by a vote of at least three-quarters of the directors comprising the Incumbent Board, or whose nomination for election by CenterState’s shareholders was approved by the nominating committee serving under an Incumbent Board, shall be considered a member of the Incumbent Board.

3. 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 (a) when delivered personally to such party or (b) provided that a written acknowledgment of receipt is obtained, five (5) days after being sent by prepaid certified or registered mail, or (c) 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 ).

The sole and exclusive venue for any civil action, counterclaim, proceeding, or litigation arising out of or relating to this Agreement shall be the courts of record of the State of Georgia in Fulton County or the United States District Court, Northern District of Georgia. Each party consents to the jurisdiction of such Georgia courts in any such civil action, counterclaim, proceeding, or litigation and waives any objection to the laying of venue of any such civil action, counterclaim, proceeding, or litigation in such Georgia courts.

7. Counterparts . This Agreement may be executed (and delivered via facsimile, email of a “.pdf” file 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.

8. Entire Agreement . This Agreement constitutes the entire agreement between the parties hereto and supersedes all prior agreements, understandings and arrangements, oral or written, between the parties hereto with respect to the subject matter hereof.

WHEREAS, the execution and delivery of this Agreement is a condition to the willingness of CSFL to enter into the Merger Agreement; and

WHEREAS , this Agreement supersedes in its entirely that certain Employment Agreement by and between NCC and National Bank of Commerce and the Executive, dated November 29, 2017, which Employment Agreement shall terminate and be of no further force and effect as of the Effective Time of the Merger;

NOW THEREFORE, in consideration of these premises, the mutual covenants contained herein, and other good and valuable consideration the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

ARTICLE 1

EMPLOYMENT

1.1 Employment . Effective as of the Employment Date , the Bank shall employ the Executive to serve as Chief Executive Officer, subject to the terms and conditions of this Agreement and for the period stated in S ection 1 .2. The Executive shall serve under the direction of the Board of Directors of the Bank and shall have such duties and responsibilities as are consistent with the Chief Executive Officer’s position for a bank of similar size and complexity as the Bank. The Executive shall exclusively devote full working time, energy, and attention to the business of the Bank and to the promotion of the Bank's interests throughout the term of this Agreement. The Executive shall serve the Bank faithfully, diligently, competently, and to the best of the Executive's ability. Without the prior written consent of the Bank, the Executive shall not render services to or for any person, firm, bank, or other entity or organization in exchange for compensation, regardless of the form in w hich the compensation is paid and regardless of whether it is paid d i rectly or indirectly to the Executive. Nothing in this Section 1.1 shall prevent the Executive from managing his personal investments and affairs, or engaging in community and charitable activities, provided that doing so does not materially interfere with the proper performance of the Executive's duties and responsibilities under this Agreement.

1.2 Term . The initial term of employment shall be a period of three years, commencing on the E ffective Date and expiring on the close of business at the end of three (3) years from the E ffective Date, subject to earlier termination or extension as provided herein (“Term”). On the first anniversary of the E ffective Date and on each anniversary thereafter, the Executive's employment shall be extended automatically for one additional year unless the Bank's Board of Directors or the Executive determine that the T erm shall not be extended. If the Board of Directors or the Executive determine not to extend the T erm, such party shall notify the other party in writing at least 90 days prior to the anniversary of the E ffective Date. If the Bank’s Board of Directors or the Executive decides not to exten d the term of employment, this Agreement shall nevertheless remain in force until th e then employment t erm expires. The B oard's decision not to extend the term of employment shall not by itself give the Executive any rights under this Agreement to claim an adverse change in position, compensation, or circumstances or otherwise to cla i m any entitlement to severance benefits under Article 4 of this Agreement.

ARTICLE 2

COMPENSATION

2.1 Base Salary . In consideration of the Executive's performance of the obligations under this Agreement, during the Term, the Bank shall pay or cause to be paid to the Executive a salary at the annual rate of not less than $500,000 (as may be increased from time to time, the " Base Salary''), payable in installments in accordance with the Bank's regular payroll policies and procedures. The Executive's salary shall be reviewed annually by the Bank’s Board of Directors or by the Board commit tee having jurisdiction over executive compensation. In the discretion of the Board of Directors or the Board committee having jurisdiction over executive compensation, the Executive's Base Salary may be increased at any time and from time to time. However, the Executive's Base Salary shall not be reduced at any time during the Term.

2.2 Incentive Compensation . For each calendar year during the Term, the Executive shall be eligible to participate in the Bank’s incentive compensation plans, which includes a cash bonus plan and an equity based grant plan, each of which are subject to the terms and conditions and objectives of the respective plan. The Executive’s target incentive compensation opportunity under the cash incentive plan shall be 60% of the Executive’s Base Salary, which incentive opportunity shall be based upon the achievement of such objectives and goals as shall be established by the Bank for the Executive from time to time, and subject to the terms and conditions and other objectives and goals of the incentive plan generally, as applied to all participants in the plan, including a deferral of a percentage of the cash bonus, as well as the other terms and conditions of this Agreement.

ARTICLE 3

EMPLOYMENT TERMINATION

3.1 Termination Because of Death or Disability.

(a) Death. The Executive's employment shall terminate automatically at the Executive's death. The Executive's estate shall receive any sums due to the Executive as Base Salary and reimbursement of expenses incurred through the date of death, and any bonus or incentive compensation earned (as defined in the plan or arrangement under which such bonus or incentive co m pensation is awarded) through the date of death, i ncluding any unvested amounts awarded for previous years. F or twelve months after the Executive's death, the Bank shall provide without cost to the Executive's family continuing health care coverage under COBRA substantially identical to that provided for the Executive as of the date of death.

(b) Disability. The Bank may terminate the Executive's employment if the Executive becomes disabled, by delivery of written notice to the Executive 30 days prior to the date of termination. For purposes of this Agreement, the Executive shall be considered “disabled” if an independent physician selected by the Bank and reasonably acceptable to the Executive or the Executive's legal representative determines that, because of illness or accident, the Executive is unable to perform the Executive's duties and will be unable to perform the Executive's duties for a period of 90 consecutive days, and the Insurance Company that is providing the Executive's disability insurance coverage concurs that the Executive is considered " disabled" pursuant to the terms and conditions of the insurance policy in place as contemplated in Section 2.3(a). The Executive shall not be considered disabled, however, if the Executive returns to work on a full-time basis within 30 days after the Bank gives notice of termination due to disability. If the Executive’ s employment terminates because of disability, the Executive shall receive the Base Salary earned through the date on which termination became effective, any bonus or incentive compensation earned (as defined in the plan or arrangement under which such bonus or incentive co m pensation is awarded) but unpaid to the Executive, any payments the Executive is eligible to receive under any disability insurance program in which the Executive participates, and such other benefits to

which the Executive may be entitled under the Bank's benefit plans, policies, and agreements (including any individual agreements to which the Bank and the Executive may be a party), or other provisions of this Agreement.

3.2 Involuntary Termination with Cause . The Bank may terminate the Executive's employment with “Cause” (as defined below). If the Executive's employment terminates with Cause, the Executive shall receive the Base Salary through the date on which termination becomes effective and reimbursement of expenses to which the Executive is entitled when termination becomes effective. The Executive shall not be deemed to have been terminated with Cause under this Agreement unless and until there is delivered to the Executive a copy of a resolution adopted at a meeting of the Board of Directors called and held for the purpose, which resolution shall (x) contain findings that in the Board's good faith opinion the Executive has committed an act constituting Cause, and (y) specify the particulars thereof. For purposes of this Agreement, “Cause” means any of the following:

	(a)	incompetence or dishonesty in Executive’s job performance, gross negligence, deliberate neglect of duties, willful malfeasance or misconduct in performance or failure to substantially perform the duties assigned to the Executive by the Bank;
	(b)	conviction of a felony or of any offense involving moral turpitude, dishonesty, breach of trust, organized crime or racketeering;
	(c)	fraud, disloyalty, dishonesty, or willful violation of any law or significant Bank policy committed in connection with the Executive’s employment; or
	(d)	the Executive’s unreasonable and/or abusive use of addictive substances, which in the Bank’s reasonable judgment, interferes with the Executive’s ability to perform his duties.

3.3 Involuntary Termination Without Cause and Voluntary Termination with Good Reason. With written notice to the Executive 90 days in advance, the Bank may terminate the Executive's employment without Cause. Termination shall take effect at the end of the 90-day period. With advance written notice to the Bank as provided in clause (b) below, the Executive may terminate employment with Good Reason. If the Executive's employment terminates involuntarily without Cause or voluntarily but with Good Reason, the Executive shall be entitled to the benefits specified in Article 4 of this Agreement. For purposes of this Agreement a voluntary termination by the Executive shall be considered a voluntary termination with Good Reason if the conditions of the safe-harbor definition of good reason contained in IRC S ection 409A are satisfied, as the same may be amended from time to time (“Good Reason”). References in this Agreement to IRC S ection 409A include rules, regulations, and guidance of general application issued by the Department of the Treasury under IRC Section 409A. For purposes of clarification and without intending to affect the foregoing reference to IRC Section 409A for the definition of Good Reason, as of the Effective Date, the safe-harbor definition of separation from service for good reason in Rule 1.409A-1(n)(2)(ii) would provide as follows:

(a) A voluntary termination by the Executive if any of the following occur without the Executive’s advance written consent:

(w)

A reduction in the Executive’s Base Salary;

(x)

A material diminution of the Executive’s authority, duties, or responsibilities;

(y)

A material change in the principal office location at which the Executive must perform services for the Bank, which, for purposes of this provision shall be a

location outside the 25 mile radius either from the Executive’s existing office location or outside of the 25 mile radius from the Bank’s Atlanta, Georgia location; or

(z)

Any other action or inaction that constitutes a material breach by the Bank of this Agreement.

(b) The Executive must give notice to the Bank of the existence of one or more of the conditions described in clause (a ) within 90 days after the initial existence of the condition, and the Bank shall have 30 days thereafter to remedy the condition. In addition, the Executive's voluntary termination because of the existence of one or more of the conditions described in clause (a) must occur within twelve months after the initial existence of the condition

3.4 Voluntary Termination by the Executive Without Good Reason . If the Executive terminates employment voluntarily but without Good Reason, the Executive shall receive the Base Salary and any expense reimbursement to which the Executive is entitled through the date on which termination becomes effective.

3.5 Termination Generally . All files, records, documents, manuals, books, forms, reports, memoranda, studies, data, calculations recordings or correspondence, in whatever form they may exist, and all copies, abstracts and summaries of the foregoing, and all physical items related to the business of the Bank, its affiliates, and their respective directors and officers, whether of a public nature or not and whether prepared by Executive or not, are, and at employment termination, shall remain the exclusive property of the Bank, and without the Bank's advance written consent, shall not be removed from Bank premises except as required in the course of providing services under this Agreement, and at termination shall be promptly returned by the Executive to the Bank.

ART I CLE 4

SEVERANCE COMPENSATION

4.1 Cash Severance after Termination Without Cause or Termination with Good Reason . If the Executive's employment is terminated by the Bank without Cause or by the Executive voluntarily but with Good Reason, the Bank shall pay to the Executive, within thirty (30) days after the Executive's employment terminates with the Bank (or if the Executive and the Bank have not entered into a release as described in Section 4.3 below in the initial thirty (30) day period, up to ninety (90) days after the Executive's employment terminates), in a single lump sum cash without discount for the time value of money in an amount equal to one and one half (1 ½) times the sum of (x) the Executive’s Base Salary, and (y) the full value of the target bonus earned by the Executive (whether payable in cash or another form under the Annual Incentive Plan or similar plan) immediately preceding the year in which the employment of the Executive terminates. The Bank and the Executive acknowledge and agree that the compensation and benefits under this section 4.1 shall not be payable if, on the date of termination, compensation and benefits are payable or shall have been paid to the Executive under Article 5 of this Agreement.

4.2 Post-Termination Insurance Coverage . (a) Subject to S ection 4.2(b), if the Executive's employment is terminated by the Bank without Cause or by the Executive voluntarily but with Good

Reason, the Bank shall continue or cause to be continued at the Bank's expense and on behalf of the Executive and the Executive's dependents and beneficiaries medical and dental insurance coverage as i n effect during and in accordance with the same schedule prevailing in the 1 2 months preceding the date of the Executive's termination. The medical and dental insurance benefits provided by this S ection 4.2(a)

shall be reduced if the Executive obtains medical or dental insurance benefits through another employer,

or eliminated entirely if the other employer's insurance benefits are equivalent or superior to the benefits provided under this S ection 4.2(a). If the insurance benefits are reduced, they shall be reduced by an amount such that the Executive's aggregate insurance benefits for the period specified in this section 4.2(a) are equivalent to the benefits to which the Executive would have been entitled had the Executive not obtained medical or dental insurance benefits through anothe r employer . The medical and dental insurance coverage and disability benefit shall continue until the first to occur of (w) the Executive's return to employment with the Bank or anothe r employer providing equivalent or superior insurance benefits, (x) the Executive's attainment of age 65, (y) the Executive's death, or (z) the end of the T erm remaining under this Agreement when the Executive's employmen t terminates. This S ection 4.2 shall not be interpreted to limit any benefits to which the Executive or the Executive's dependents or beneficiaries may be entitled under any of the Bank's employee benefit plans, agreements, programs, or practices after the Executive's employmen t terminates, including, without any limitation, any retiree medical benefits.

(b) If (x ) under the terms of the applicable policy or policies for the insurance benefits specified in Section 4.2(a), it is not possible to continue the Executive's coverage, or (y) when employment termination occurs, (i) the Executive is a specified employee within the meaning of IRC S ection 409A, (ii) if any of the continued insurance benefits specified in S ection 4.2(a) would be considered deferred compensation under S ection 409A, or (iii) if an exemption from the six-month delay requirement of Section 409A(a)(2)(B)(i) is not available for that particular insurance benefit, instead of continued insurance coverage under S ection 4.2(a), the Bank shall pay to the Executive in a single l ump sum an amount i n cash equal to the present value of the Bank's projected cost to maintain that particular insurance benefit had the Executive’s employment not terminated, assuming continued coverage for the lesser of the n umber of months remaining in the term of this A greement or the number of months until the Executive attains age 65. The lump-sum payment shall be made 30 days after employment termination or, if S ection 4.2(b) app l ies and a six-month delay is required under IRC Section 409A, on the first day of the seventh month after the month in which the Executive’s employment terminates.

4.3 Release . The Executive shall be entitled to no compensation or other benefits under this Article 4 unless (x) within 90 days after the Executive's employment termination the Executive shall have entered into a release in form satisfactory to the Bank acknowledging the Executive's remaining obligations and discharging the Bank, as well as the Bank's officers, directors, and employees for their actions for or on behalf of the Bank, from any other claims or obligations arising out of the Executive' s employment by the Bank, including the circumstances of the Executive's employment termination, and (y) within that 90-day period the release shall have become irrevocable, final, and binding on the Executive under all applicable law, with expiration of all applicable revocation periods. I f the final day of the 90-day period for execution and finality of a liability release occurs in the taxable year after the year in which the Executive’s employment termination occurs, the benefits to the Executive under this Article 4 shall be payable in the taxable year in which the 90-day period ends and shall not be paid in the taxable year in which employment termination occurs. Nothing in this Section 4.3 is intended to abrogate the Executive’s review and revocation rights under the Older Workers’ Benefit Protection Act that may be included in any such release, and the 90-day period shall be extended if necessary to permit Executive to exercise such rights. The non-compete and other covenants contained in Article 7 of this Agreement are not contingent on the Executive entering into a release under this Section 4.3 and shall be effective regardless of whether the Executive enters into the release.

ARTICLE 5

CHANGE IN CONTROL

5.1 Change in Control Benefits . If (i) a Change in Control occurs after the Effective Date and during the term of this Agreement, and (ii) within 12 months following such Change in Control, either the Corporation terminates the Executive’s employment without Cause or the Executive terminates the

Executive’s employment with Good Reason, then the Bank shall promptly make or cause to be made a lump-sum payment to the Executive in an amount in cash equal to two and one-half (2 ½ ) times the sum of (x) the Executive’s Base Salary, and (y) the highest annual bonus earned by the Executive during the prior three years (including the full value of the annual award, whether payable in cash or another form, earned under the Annual Incentive Plan or similar plan) immediately preceding the year in which the Change in Control occurs (the “ Change in Control Payment ”) . The Change in Control Payment payable to the Executive hereunder shall not be reduced to account for the time value of money or discounted to present value. If the Executive receives a Change in Control Payment under this S ection 5.1 , the Executive shall not be entitled to any addit ional severance benefits under S ection 4.1 of this Agreement after employment termination. The Executive shall be e ntitled to benefits under this S ection 5.1 on no more than one occasion during the term of this Agreement.

TERMINATION

7.1 Restrictions on the Executive’s Employment and Post-Employment Activities . The restrictions in this Article 7 have been negotiated, presented to and accepted by the Executive contemporaneous with the offer and acceptance by the Executive of this Agreement. The Bank's decision to enter into this Agreement is conditioned upon the Executive's agreement to be bound by the restrictions contained in this Article 7 . For purposes of this Article 7, references to “Bank” include not only the Bank but also CenterState Bank Corporation and any subsidiary or affiliate.

(a) Promise of no solicitation . The Executive promises and agrees that, based on its experience with and relationship to the Bank and its Customers during the Restricted Period (as defined below), the Executive shall:

not accept the Financial Products or Services business of any Customer or provide Financial Products or Services to any Customer on behalf of anyone other than the Bank,

(b) Promise of no competition . The Executive promises and agrees that, during the Restricted Period and in the Restricted Territory, the Executive shall not contribute in any manner to any other entity (as an employee, officer, director, stockholder, consultant, contractor, agent, partner or other similar capacity), engage in any activity that would require disclosure of confidential information (as

defined herein) or engage, undertake or participate in the business of providing, selling, marketing or distributing Financial Products or Services of a similar nature, kind or variety (x) as offered by the Bank to Customers during the two years immediately before the Executive’s employment termination with the Bank, and (y) as offered by the Bank to any of its Customers during the Restricted Period.

Nothing herein is intended to restrict the Executive or the Bank from testifying truthfully in response to any lawfully served subpoena or other legal process.

(e) Acknowledgment . The Executive and the Bank acknowledge and agree that the provisions of this Article 7 have been negotiated and carefully determined to be reasonable and necessary for the protection of legitimate business interests of the Bank. Both parties agree that a violation of Article 7 is likely to cause immediate and irreparable harm that will give rise to the need for court ordered injunctive relief. In the event of a breach or threatened breach by the Executive of any provision of this Agreement, the Bank shall be entitled to obtain an injunction without bond restraining the Executive from violating the terms of this Agreement and to institute an action against the Executive to recover damages from the Employee for such breach. These remedies for default or breach are in addition to any other remedy or form of redress provided under Florida law. The parties acknowledge that the provisions of this Article 7 survive termination of the employment relationship. The parties agree that if any of the provisions of this Article 7 are deemed unenforceable by a court of competent jurisdiction, that such provisions may be stricken as independent clauses by the court in order to enforce the remaining territory restrictions and that the intent of the parties is to afford the broadest restriction on post-employment activities as set forth in this Agreement.

8.2 Governing Law, Jurisdiction and Forum . This Agreement shall be construed under and governed by the internal laws of the State of Florida, without giving effect to any conflict of laws provision or rule (whether of the State of Florida or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Florida. By entering into this Agreement, the Executive acknowledges that the Executive is subject to the jurisdiction of both the federal and state courts in the State of Florida. Any actions or proceedings instituted under this Agreement shall be brought and tried solely in courts located in Polk County, Florida or in the federal court having jurisdiction in Winter Haven, Florida.

If any provision of this Agreement is held by a court of competent jurisdiction to be indefinite, invalid, void or voidable, or otherwise unenforceable, the remainder of this Agreement shall continue in full force and effect unless that would clearly be contrary to the intentions of the parties or would result in an injustice.

8.6 Captions and Counterparts . The captions in this Agreement are solely for convenience. The captions do not define, limit, or describe the scope or intent of this Agreement. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original but all of which together shall constitute one and the same instrument.

8.7 Amendment and Waiver . This Agreement may not be amended, released, discharged, abandoned, changed, or modified except by an instrument in writing signed by each of the parties hereto. The failure of any party hereto to enforce at any time any of the provisions of this Agreement shall not be construed to be a waiver of any such provision or affect the validity of this Agreement or any part thereof or the right of any party thereafter to enforce each and every such provision. No waiver or any breach of this Agreement shall be held to be a waiver of any other or subsequent breach.

8.8 FDIC Part 359 Limitations . Despite any contrary provision within this Agreement, any

Both parties hereto having participated in the negotiation and drafting of this Agreement, they hereby agree that there shall not be strict interpretation against either party in any review of this Agreement in which interpretation of the Agreement is an issue.

8.10 Limitation of Payments and Benefits – IRC Section 280G . If any of the payments or benefits received or to be received by the Executive (including without limitation any payments or benefits received in connection with the termination of Executive’s employment due to a change in Control or otherwise) under this Agreement or under any other arrangement or agreement or otherwise, shall constitute “parachute payments” under Section 280G of the IRC (the “280G Payments’), and would but for this section 8.10, be subject to the excise tax under Section 4999 of the IRC, then prior to making such 280G Payments, the parties agree to take all reasonable actions, including hiring appropriate independent consulting and/or accounting firms, and execute such documents as may be necessary and appropriate to minimize the payments or benefits characterized as, or constituting, “parachute payments” within the meaning of 280G of the IRC, provided, however, that to the extent that such actions result in the excise tax still being imposed, then a calculation shall be made comparing (i) the Net Benefit (as defined below) to the Executive of the 280G Payments after payment of the excise tax, to (ii) the Net Benefit to the Executive if the 280G Payments are limited to the extent necessary to avoid the imposition of the excise tax to any portion of the payment. If the amount calculated under (i) is less than (ii) then the payments will be reduced to the extent necessary to avoid the imposition of the excise tax to any portion of the 280G Payments. For purposes of this Section 8.10, the term “Net Benefit” shall mean the present value of the 280G Payments net of all federal, state, local, foreign, employment and excise taxes. Any reduction made pursuant to this section 8.10 shall be made in a manner determined by the Bank to comply with Section 409A of the IRC.

8.11 Compliance with IRC Section 409A . The Bank and the Executive intend that, this Agreement, including the exercise of authority or discretion under this Agreement, shall comply with IRC Section 409A. If the Executive’s employment terminates when the Executive is a specified employee, as defined in IRC Section 409A, and if any payments under this Agreement, including Article 4, will result in additional tax or interest to the Executive because of Section 409A, then despite any provision of this Agreement to the contrary, the Executive shall not be entitled to the payments until the earliest of ( x ) the date that is at least six months after termination of the Executive’s employment for reasons other than the Executive’s death, ( y ) the date of the Executive’s death, or ( z ) any earlier date that does not result in additional tax or interest to the Executive under IRC Section 409A. As promptly as possible after the end of the period during which payments are delayed under this provision, the entire amount of the delayed payments shall be paid to the Executive in a single lump sum. If any provision of this Agreement does not satisfy the requirements of IRC Section 409A, the provision shall be applied in a manner consistent with those requirements despite any contrary provision of this Agreement. If any provision of this Agreement would subject the Executive to additional tax or interest under IRC Section 409A, the Bank shall reform the provision. However, the Bank shall maintain to the maximum extent practicable the original intent of the applicable provision without subjecting the Executive to additional tax or interest, and the Bank shall not be required to incur any additional compensation expense as a result of the reformed provision. References in this Agreement to IRC Section 409A include rules, regulations, and guidance of general application issued by the Department of the Treasury under IRC Section 409A.

In Witness Whereof , the parties have executed this Employment Agreement as of the date first written above.

Effective as of the Employment Date, the Bank shall employ the Executive to serve as Chief Financial Officer of CSFL and the Bank, subject to the terms and conditions of this Agreement and for the period stated in Section 1 .2. The Executive shall serve under the direction of the Board of Directors of CSFL and the Bank and shall have such duties and responsibilities as are consistent with the Chief Financial Officer’s position for a bank of similar size and complexity as the Bank. The Executive shall exclusively devote full working time, energy, and attention to the business of CSFL and the Bank and to the promotion of each entity’s interests throughout the term of this Agreement. The Executive shall serve CSFL and the Bank faithfully, diligently, competently, and to the best of the Executive's ability. Without the prior written consent of the Bank, the Executive shall not render services to or for any person, firm, bank, or other entity or organization in exchange for compensation, regardless of the form in which the compensation is paid and regardless of whether it is paid directly or indirectly to the Executive. Nothing in this Section 1.1 shall prevent the Executive from managing his personal investments and affairs, or engaging in community and charitable activities, provided that doing so does not materially interfere with the proper performance of the Executive's duties and responsibilities under this Agreement.

1.2 Term . The initial term of employment shall be a period of three years, commencing on the Effective Date and expiring on the close of business at the end of three (3) years from the Effective Date, subject to earlier termination or extension as provided herein (“Term”). On the first anniversary of the Effective Date and on each anniversary thereafter, the Executive's employment shall be extended automatically for one additional year unless the Bank's Board of Directors or the Executive determine that the Term shall not be extended. If the Board of Directors or the Executive determine not to extend the Term, such party shall notify the other party in writing at least 90 days prior to the anniversary of the Effective Date. If the Bank’s Board of Directors or the Executive decides not to extend the term of employment, this Agreement shall nevertheless remain in force until the then employment term expires. The Board's decision not to extend the term of employment shall not by itself give the Executive any rights under this Agreement to claim an adverse change in position, compensation, or circumstances or otherwise to claim any entitlement to severance benefits under Article 4 of this Agreement.

ARTICLE 2

COMPENSATION

2.1 Base Salary . In consideration of the Executive's performance of the obligations under this Agreement, during the Term, the Bank shall pay or cause to be paid to the Executive a salary at the annual rate of not less than $475,000 (as may be increased from time to time, the "Base Salary''), payable in installments in accordance with the Bank's regular payroll policies and procedures.

ARTICLE 3

EMPLOYMENT TERMINATION

3.1 Termination Because of Death or Disability.

(a) Death. The Executive's employment shall terminate automatically at the Executive's death. The Executive's estate shall receive any sums due to the Executive as Base Salary and reimbursement of expenses incurred through the date of death, and any bonus or incentive compensation earned (as defined in the plan or arrangement under which such bonus or incentive compensation is awarded) through the date of death, including any unvested amounts awarded for previous years. For twelve months after the Executive's death, the Bank shall provide without cost to the Executive's family continuing health care coverage under COBRA substantially identical to that provided for the Executive as of the date of death.

(b) Disability. The Bank may terminate the Executive's employment if the Executive becomes disabled, by delivery of written notice to the Executive 30 days prior to the date of termination. For purposes of this Agreement, the Executive shall be considered “disabled” if an independent physician selected by the Bank and reasonably acceptable to the Executive or the Executive's legal representative determines that, because of illness or accident, the Executive is unable to perform the Executive's duties and will be unable to perform the Executive's duties for a period of 90 consecutive days, and the Insurance Company that is providing the Executive's disability insurance coverage concurs that the Executive is considered "disabled" pursuant to the terms and conditions of the insurance policy in place as contemplated in Section 2.3(a). The Executive shall not be considered disabled, however, if the Executive returns to work on a full-time basis within 30 days after the Bank gives notice of termination due to disability. If the Executive’ s employment terminates because of disability, the Executive shall

receive the Base Salary earned through the date on which termination became effective, any bonus or incentive compensation earned (as defined in the plan or arrangement under which such bonus or incentive compensation is awarded) but unpaid to the Executive, any payments the Executive is eligible to receive under any disability insurance program in which the Executive participates, and such other benefits to which the Executive may be entitled under the Bank's benefit plans, policies, and agreements

(including any individual agreements to which the Bank and the Executive may be a party), or other

provisions of this Agreement.

	(a)	incompetence or dishonesty in Executive’s job performance, gross negligence, deliberate neglect of duties, willful malfeasance or misconduct in performance or failure to substantially perform the duties assigned to the Executive by the Bank;
	(b)	conviction of a felony or of any offense involving moral turpitude, dishonesty, breach of trust, organized crime or racketeering;
	(c)	fraud, disloyalty, dishonesty, or willful violation of any law or significant Bank policy committed in connection with the Executive’s employment; or
	(d)	the Executive’s unreasonable and/or abusive use of addictive substances, which in the Bank’s reasonable judgment, interferes with the Executive’s ability to perform his duties.

3.3 Involuntary Termination Without Cause and Voluntary Termination with Good Reason. With written notice to the Executive 90 days in advance, the Bank may terminate the Executive's employment without Cause. Termination shall take effect at the end of the 90-day period. With advance written notice to the Bank as provided in clause (b) below, the Executive may terminate employment with Good Reason. If the Executive's employment terminates involuntarily without Cause or voluntarily but with Good Reason, the Executive shall be entitled to the benefits specified in Article 4 of this Agreement. For purposes of this Agreement a voluntary termination by the Executive shall be considered a voluntary termination with Good Reason if the conditions of the safe-harbor definition of good reason contained in IRC Section 409A are satisfied, as the same may be amended from time to time (“Good Reason”). References in this Agreement to IRC Section 409A include rules, regulations, and guidance of general application issued by the Department of the Treasury under IRC Section 409A. For purposes of clarification and without intending to affect the foregoing reference to IRC Section 409A for the definition of Good Reason, as of the Effective Date, the safe-harbor definition of separation from service for good reason in Rule 1.409A-1(n)(2)(ii) would provide as follows:

(a) A voluntary termination by the Executive if any of the following occur without the Executive’s advance written consent:

(w)

A reduction in the Executive’s Base Salary;

(x)

A material diminution of the Executive’s authority, duties, or responsibilities;

(y)

A material change in the principal office location at which the Executive must perform services for the Bank, which, for purposes of this provision shall be a location outside the 25 mile radius either from the Executive’s existing office location or outside of the 25 mile radius from the Bank’s Atlanta, Georgia location; or

(z)

Any other action or inaction that constitutes a material breach by the Bank of this Agreement.

(b) The Executive must give notice to the Bank of the existence of one or more of the conditions described in clause (a) within 90 days after the initial existence of the condition, and the Bank shall have 30 days thereafter to remedy the condition. In addition, the Executive's voluntary termination because of the existence of one or more of the conditions described in clause (a) must occur within twelve months after the initial existence of the condition

ARTICLE 4

SEVERANCE COMPENSATION

4.2 Post-Termination Insurance Coverage . (a) Subject to Section 4.2(b), if the Executive's employment is terminated by the Bank without Cause or by the Executive voluntarily but with Good Reason, the Bank shall continue or cause to be continued at the Bank's expense and on behalf of the Executive and the Executive's dependents and beneficiaries medical and dental insurance coverage as in effect during and in accordance with the same schedule prevailing in the 12 months preceding the date of the Executive's termination. The medical and dental insurance benefits provided by this Section 4.2(a) shall be reduced if the Executive obtains medical or dental insurance benefits through another employer,

4.2(a) are equivalent to the benefits to which the Executive would have been entitled had the Executive not obtained medical or dental insurance benefits through another employer.

Exhibit 99.1

FOR IMMEDIATE RELEASE

CenterState Bank Corporation

Announces Acquisition of National Commerce Corporation

WINTER HAVEN, Fla. and BIRMINGHAM, Ala., November 26, 2018 /PRNewswire/ -- CenterState Bank Corporation (Nasdaq-GS: CSFL) ("CenterState" or the "Company") and National Commerce Corporation (Nasdaq: NCOM) ("National Commerce"), jointly announced today the signing of a definitive agreement pursuant to which National Commerce will merge with and into CenterState in an all-stock transaction. This combination of two high-performing banks will create a leading Southeastern regional bank, with branches in Florida, Georgia and Alabama. As of September 30, 2018 and excluding purchase accounting, the combined company has pro forma total assets of $16.4 billion, gross loans of $11.5 billion, deposits of $12.8 billion and a market capitalization of approximately $3.2 billion. Over 75% of the pro forma deposit base will be in Florida.

Upon completion of the merger, Richard Murray, IV, Chairman and Chief Executive Officer of National Commerce, will join CenterState as Chief Executive Officer of the Company’s wholly-owned bank subsidiary, CenterState Bank, N.A., and William E. Matthews, V, President and Chief Financial Officer of National Commerce, will join CenterState as Chief Financial Officer of both the bank and the holding company.

"We have enjoyed a nineteen year business relationship with Richard, Will and other members of the National Commerce team that confirms our cultural alignment,” said John Corbett, President & Chief Executive Officer of CenterState. “This partnership not only strengthens our management team, but it also deepens our franchise in our core markets of Orlando, Tampa, Jacksonville, and Atlanta. We are also excited to welcome a seasoned team of Alabama bankers with a proven record of success.”

“For years, we have had great respect and admiration for CenterState and we are thrilled to play an important role in helping build upon our common culture and values,” noted Richard Murray. “This partnership enables National Commerce stockholders to benefit from accelerating growth and capitalizing on opportunities in our markets. By joining up and joining in with the CenterState team, together we will realize benefits it would have taken us years to accomplish independently.”

Subject to the terms of the merger agreement, National Commerce stockholders will receive 1.65 shares of CSFL common stock for each outstanding share of National Commerce common stock. Each outstanding option to purchase shares of National Commerce common stock will be assumed by CenterState and become an option to purchase shares of CenterState common stock, with the exercise price and number of shares underlying the option adjusted to reflect the

exchange ratio of 1.65. Based on CSFL's stock price of $24.25 as of November 23, 2018, this equates to a per share value of $40.01 and an aggregate transaction value of $850.4 million. Additionally, three National Commerce directors will join both the Company board and the CenterState Bank board and one additional director will join the CenterState Bank board.

The transaction is expected to result in mid-single-digit EPS accretion on a fully phased in basis and limited tangible book value dilution, expected to be earned back in approximately two years.

The merger agreement has been unanimously approved by the board of directors of each of National Commerce and CenterState. Completion of the merger is subject to customary closing conditions, including receipt of required regulatory approvals and the approval by the stockholders of both National Commerce and CenterState. The transaction is expected to close in the 2nd quarter of 2019.

Raymond James & Associates, Inc. served as financial advisor and Nelson Mullins Riley and Scarborough LLP served as legal counsel to CenterState in the transaction. Keefe, Bruyette & Woods, Inc. served as financial advisor and Maynard Cooper & Gale, P.C. served as legal counsel to National Commerce in the transaction.
