Ratio”) shares of CenterState Common Stock (the “Per Share Stock Consideration”), and (ii) $3.00 plus any dividends payable in accordance with Section 2.2(c), and any cash in lieu of fractional shares as specified
in Section 2.2(f), (collectively, the “Per Share Cash Consideration” and, together with the Per Share Stock Consideration, the “Merger Consideration”). For the avoidance of doubt, prior to the Effective Time,
all the outstanding shares of First Southern’s Common Equivalent Convertible Participating Voting Preferred Stock, Series C (the “Series C Preferred Stock”), shall be converted into First Southern Common Stock (or First
Southern Non-Voting Common Stock, if required by the Certificate of Designations, provided that such First Southern Non-Voting Common Stock will be treated as First Southern Common Stock and Exchangeable Shares for purposes of this Agreement)
in accordance with the provisions of the Certificate of Designations for the Series C Preferred Stock set forth in the Articles of Amendment to the articles of incorporation of First Southern (the “Certificate of Designations”), and
such converted shares of Series C Preferred Stock shall be treated for all purposes hereunder, including payment of the Merger Consideration, as First Southern Common Stock and Exchangeable Shares. All of the Exchangeable Shares converted into the
right to receive the Merger Consideration pursuant to this Article I shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and each certificate previously representing any such shares
of First Southern Common Stock (each, a “Certificate”) and non-certificated share of First Southern Common Stock represented by book-entry (“Book-Entry Shares”) shall thereafter represent only the right to receive
the Merger Consideration into which 

  
 2 

 
the shares of First Southern Common Stock represented by such Certificate or Book-Entry Shares have been converted pursuant to this Section 1.4 and any cash in lieu of fractional shares as
specified in Section 2.2(f), as well as any dividends to which holders of First Southern Common Stock become entitled in accordance with Section 2.2(c). 

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

(d) Notwithstanding anything in this Agreement to the contrary, shares of First Southern Common Stock that are issued and outstanding
immediately prior to the Effective Time and which are held by a shareholder who did not vote in favor of the Merger (or consent thereto in writing) and who is entitled to demand and properly demands the fair value of such shares pursuant to, and who
complies in all respects with, the provisions of Sections 607.1301 to 607.1333 of the FBCA (the “Dissenting Shares”), shall not be converted into or be exchangeable for the right to receive the Merger Consideration, but instead the
holder of such Dissenting Shares shall be entitled to payment of the fair value of such shares in accordance with the provisions of Sections 607.1301 to 607.1333 of the FBCA (and at the Effective Time, such Dissenting Shares shall no longer be
outstanding and shall automatically be cancelled and shall cease to exist), unless and until such holder shall have failed to perfect such holder’s right to receive, or shall have effectively withdrawn or lost rights to demand or receive, the
fair value of such shares of First Southern Common Stock under such provisions of the FBCA. If any shareholder dissenting pursuant to Sections 607.1301 to 607.1333 of the FBCA and this Section 1.4(d) shall have failed to perfect or shall have
effectively withdrawn or lost such right, such holder’s shares of First Southern Common Stock shall thereupon be treated as if they had been converted into and become Exchangeable Shares as of the Effective Time, eligible to receive the Merger
Consideration in accordance with Section 1.4(b), without any interest thereon. First Southern shall give CenterState (i) prompt notice of any written notices to exercise dissenters’ rights in respect of any shares of First Southern
Common Stock, attempted withdrawals of such notices and any other instruments served pursuant to the FBCA and received by First Southern relating to dissenters’ rights and (ii) the opportunity to participate in negotiations and proceedings
with respect to demands for fair value under the FBCA. First Southern shall not, except with the prior written consent of CenterState, voluntarily make any payment with respect to, or settle, or offer or agree to settle, any such demand for payment.

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

 ARTICLE II 

DELIVERY OF MERGER CONSIDERATION 

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

2.2 Delivery of Merger Consideration. 

(a) Promptly (and within five Business Days) after the Effective Time, the Exchange Agent shall mail to each holder of record of a Certificate
which immediately prior to the Effective Time represented outstanding shares of First Southern Common Stock whose shares were converted into the right to receive the Merger Consideration pursuant to Section 1.4(b), including any cash in lieu of
fractional shares of CenterState Common Stock to be issued or paid in consideration therefor and any dividends or distributions to which such holder is entitled, (i) a letter of transmittal (which shall specify that delivery shall be effected,
and risk of loss and title to each Certificate shall pass, only upon delivery of such Certificate (or affidavits of loss in lieu of such Certificate)) to the Exchange Agent and which shall be substantially in such form and have such other provisions
as shall be prescribed by the Exchange Agent Agreement (the “Letter of Transmittal”) and (ii) instructions for use in surrendering a Certificate in exchange for the Merger Consideration to be issued or paid in consideration
therefor. 
 (b) Upon surrender to the Exchange Agent of its Certificate or Certificates, accompanied by a properly completed Letter of
Transmittal, a holder of First Southern Common Stock will be entitled to receive promptly after the Effective Time the Merger Consideration, including any dividends that are payable to CenterState shareholders of record as of any date on or after
the Closing Date and cash in lieu of fractional shares of CenterState Common Stock to be issued or paid in consideration therefor in respect of the shares of First Southern Common Stock represented by its Certificate or Certificates. Until so
surrendered, each such Certificate shall represent after the Effective Time, for all purposes, only the right to receive, without interest, the Merger Consideration, including any cash in lieu of fractional shares of CenterState Common Stock to be
issued or paid in consideration therefor upon surrender of such Certificate and any dividends or distributions to which such holder is entitled pursuant to Section 2.2(c), in accordance with the provisions of this Article II. Any holder of
Book-Entry Shares shall not be required to deliver a Certificate or an executed letter of transmittal to the Exchange Agent to receive the Merger Consideration. In lieu thereof, each holder of one or more Book-Entry Shares shall automatically upon
the Effective Time be entitled to receive, and the Exchange Agent shall as soon as practicable following the Effective Time (and in any event within three (3) Business Days thereafter) pay to the holder, the Merger Consideration for each
Book-Entry Share and any cash in lieu of fractional shares of CenterState Common Stock to be issued or paid in consideration therefor and any dividends or distributions to which such holder is entitled pursuant to Section 2.2(c). 

  
 8 

 (c) Notwithstanding the provisions of Section 1.4(b), no dividends or other distributions
with respect to CenterState Common Stock shall be paid to the holder of any unsurrendered Certificate with respect to the shares of CenterState Common Stock represented thereby, in each case unless and until the surrender of such Certificate in
accordance with this Article II. Subject to the effect of applicable abandoned property, escheat or similar laws, following surrender of any such Certificate or payment of the Merger Consideration in respect of Book-Entry Shares in accordance with
this Article II, the record holder thereof shall be entitled to receive, without interest, (i) the amount of dividends or other distributions with a record date after the Effective Time theretofore payable with respect to the whole shares of
CenterState Common Stock represented by such Certificate or Book-Entry Shares and not paid or (ii) at the appropriate payment date, the amount of dividends or other distributions payable with respect to shares of CenterState Common Stock
represented by such Certificate or Book-Entry Shares with a record date after the Effective Time (but before such surrender date) and with a payment date subsequent to the issuance of the CenterState Common Stock issuable with respect to such
Certificate or Book-Entry Shares. 
 (d) In the event of a transfer of ownership of a Certificate representing First Southern Common Stock
that is not registered in the stock transfer records of First Southern, the Merger Consideration and cash in lieu of fractional shares of CenterState Common Stock and dividends or distributions payable pursuant to Section 2.2(c) shall be issued
or paid in exchange therefor to a Person other than the Person in whose name the Certificate so surrendered is registered if the Certificate formerly representing such First Southern Common Stock shall be properly endorsed or otherwise be in proper
form for transfer and the Person requesting such payment or issuance shall pay any transfer or other similar taxes required by reason of the payment or issuance to a Person other than the registered holder of the Certificate or establish to the
satisfaction of CenterState that the tax has been paid or is not applicable. The Exchange Agent (or, subsequent to the one-year anniversary of the Effective Time, CenterState) shall be entitled to deduct and withhold from any cash consideration or
cash in lieu of fractional shares of CenterState Common Stock otherwise payable pursuant to this Agreement to any holder of First Southern Common Stock such amounts as the Exchange Agent or CenterState, as the case may be, is required to deduct and
withhold under the Code, or any provision of state, local or foreign tax law, with respect to the making of such payment. To the extent the amounts are so withheld by the Exchange Agent or CenterState, as the case may be, and timely paid over to the
appropriate Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of First Southern Common Stock in respect of whom such deduction and withholding was made by the
Exchange Agent or CenterState, as the case may be. For purposes of Section 1.5, any required withholding shall be satisfied by the applicable holder tendering to the Surviving Company, the Exchange Agent or CenterState, as applicable, a number
of shares of CenterState Common Stock with a fair market value equal to the amount required to be withheld. 
 (e) After the Effective Time,
there shall be no transfers on the stock transfer books of First Southern of the shares of First Southern Common Stock that were issued and outstanding immediately prior to the Effective Time other than to settle transfers of First Southern Common
Stock that occurred prior to the Effective Time. If, after the Effective Time, Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for the Merger Consideration and any cash in
lieu of fractional shares 

  
 9 

 
of CenterState Common Stock to be issued or paid in consideration therefor and any dividends or distributions to which the holder is entitled pursuant to Section 2.2(c) in accordance with
the procedures set forth in this Article II. 
 (f) Notwithstanding anything to the contrary contained in this Agreement, no fractional
shares of CenterState Common Stock shall be issued to the holder of Book-Entry Shares or upon the surrender of Certificates for exchange, no dividend or distribution with respect to CenterState Common Stock shall be payable on or with respect to any
fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of CenterState. In lieu of the issuance of any such fractional share, CenterState shall pay to each former
shareholder of First Southern who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest whole cent) determined by multiplying (i) the Average Closing Price by (ii) the fraction of a share
(after taking into account all shares of First Southern Common Stock held by such holder at the Effective Time and rounded to the nearest one thousandth when expressed in decimal form) of CenterState Common Stock to which such holder would otherwise
be entitled to receive pursuant to Section 1.4. 
 (g) In the event any Certificate shall have been lost, stolen or destroyed, upon the
making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if reasonably required by CenterState or the Exchange Agent, the posting by such Person of a bond in such amount as CenterState may
determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration
deliverable in respect thereof pursuant to this Agreement.

ARTICLE VI 
 ADDITIONAL
AGREEMENTS 
 6.1 Regulatory Matters. 

(a) As promptly as practicable (but in no event later than ninety (90) days) following the date of this Agreement, CenterState, with the
assistance and cooperation of First Southern, shall promptly prepare and file with the SEC the Form S-4, together with the Proxy Statement which will be included in Form S-4, which shall provide for the registration of the shares to the CenterState
Common Stock to be issued as a result of the Merger. Each of CenterState and First Southern shall use its commercially reasonable best efforts to respond as promptly as practicable to any written or oral comments from the SEC or its staff with
respect to the Form S-4 or any related matters. Each of First Southern and CenterState shall use its commercially reasonable best efforts to have the Form S-4 declared effective under the Securities Act as promptly as practicable after such filing
and to maintain such effectiveness for as long as necessary to consummate the Merger and the other transactions contemplated by this Agreement. Upon the Form S-4 being declared effective, CenterState and First Southern shall thereafter mail or
deliver the Proxy Statement to their respective shareholders. CenterState shall also use its commercially reasonable best efforts to obtain all necessary state securities law or “Blue Sky” permits and approvals required to carry out the
transactions contemplated by this Agreement, and First Southern shall furnish all information concerning First Southern and the holders of First Southern Common Stock as may be reasonably requested in connection with any such action. If at any time
prior to the Effective Time any event occurs or information relating to First Southern or CenterState, or any of their respective affiliates, directors or officers, should be discovered by First Southern or CenterState that should be set forth in an
amendment or supplement to either the Form S-4 or the Proxy Statement, so that either such document would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, the Party that discovers such information shall promptly notify the other Party and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC
and, to the extent required by applicable law, disseminated to CenterState’s and First Southern’s shareholders. 

  
 44 

 (b) In addition to their obligations pursuant to Section 6.1(a), First Southern and
CenterState shall make all necessary filings with respect to the Merger and the other transactions contemplated by this Agreement under the Securities Act, the Exchange Act and applicable foreign or state securities or “Blue Sky” laws and
regulations promulgated thereunder and provide each other with copies of any such filings. CenterState and First Southern shall advise the other Party, promptly after receipt of notice thereof, of (and provide copies of any notices or communications
with respect to) the time of the effectiveness of the Form S-4, the filing of any supplement or amendment thereto, the issuance of any stop order relating thereto, the suspension of the qualification of CenterState Common Stock issuable in
connection with the Merger for offering or sale in any jurisdiction, or of any request by the SEC or its staff for amendment to the Proxy Statement or the Form S-4, comments thereon from the SEC’s staff and each Party’s responses thereto
or request of the SEC or its staff for additional information. No amendment or supplement to the Proxy Statement or the Form S-4 shall be filed without the approval of each of First Southern and CenterState, which approval shall not be unreasonably
withheld, conditioned or delayed. 
 (c) Subject to the terms and conditions set forth in this Agreement, CenterState and First Southern
shall, and shall cause their respective Subsidiaries to, use commercially reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other Party in doing, all things
necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated by this Agreement, including (i) the satisfaction of the conditions precedent to the obligations of First
Southern (in the case of CenterState) or CenterState (in the case of First Southern) to the Merger, (ii) the obtaining of all necessary consents or waivers from third parties, (iii) the obtaining of all necessary actions or no-actions,
waivers, consents, authorizations, permits, orders and approvals from, or any exemption by, any Governmental Entities and the taking of all commercially reasonable steps as may be necessary to obtain an approval or waiver from, or to avoid an action
or proceeding by any Governmental Entity, and (iv) the execution and delivery of any additional instruments necessary to consummate the Merger and to fully carry out the purposes of this Agreement. In furtherance of the foregoing, First
Southern and CenterState shall cooperate in all respects and use their commercially reasonable best efforts to seek and obtain approval from the applicable Governmental Entities of a dividend of $50 million to be paid from First Southern Bank to
First Southern immediately prior to the Closing or otherwise in connection with the completion of the Bank Merger. The Parties shall cooperate with each other and use their respective commercially reasonable best efforts to promptly prepare and
file, and cause their respective Subsidiaries to prepare and file, all necessary documentation, to effect all applications, notices, petitions and filings, to obtain as promptly as practicable all permits, consents, approvals and authorizations of
all third parties and Governmental Entities that are necessary or advisable to consummate the transactions contemplated by this Agreement (including the Merger and the Bank Merger), and to comply with the terms and conditions of all such permits,
consents, approvals and authorizations of all such third parties or Governmental Entities. In furtherance (but not in limitation) of the foregoing, CenterState shall, and shall cause CenterState Bank of Florida, N.A. to, use commercially reasonable
efforts to file any required applications, notices or other filings with the FRB, the OCC, the FDIC and applicable state banking agencies within forty-five (45) days of the date hereof. First Southern and CenterState shall have the right to
review in advance, and, to the extent practicable, each will consult the other on, in each case subject to applicable laws relating to the confidentiality of information, all the information relating to First

  
 45 

 
Southern or CenterState, as the case may be, and any of their respective Subsidiaries, that appear in any filing made with, or written materials submitted to, any third party or any Governmental
Entity in connection with the transactions contemplated by this Agreement. In exercising the foregoing right, each of the Parties shall act reasonably and as promptly as practicable. The Parties shall consult with each other with respect to the
obtaining of all permits, consents, approvals and authorizations of all third parties and Governmental Entities necessary or advisable to consummate the transactions contemplated by this Agreement, and each Party will keep the other apprised of the
status of matters relating to completion of the transactions contemplated by this Agreement. The Parties shall promptly deliver to each other copies of all filings, orders and material correspondence to and from all Governmental Entities in
connection with the transactions contemplated by this Agreement. 
 (d) Each of CenterState and First Southern shall, upon request, furnish
to the other all information concerning itself, its Subsidiaries, directors, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with the Proxy Statement, the Form S-4 or any other statement,
filing, notice or application made by or on behalf of CenterState, First Southern or any of their respective Subsidiaries to any Governmental Entity in connection with the Merger, the Bank Merger or any other transactions contemplated by this
Agreement. 
 (e) Each of CenterState and First Southern shall promptly advise the other upon receiving any communication from any
Governmental Entity the consent or approval of which is required for consummation of the transactions contemplated by this Agreement that causes such Party to believe that there is a reasonable likelihood that any Requisite Regulatory Approval will
not be obtained or that the receipt of any such approval may be materially delayed. Without limiting the foregoing, each Party shall, to the extent permitted by applicable law, promptly advise the other of the receipt of any substantive
communication from a Governmental Entity with respect to the transactions contemplated hereby and cooperate with the other in preparing any response thereto. 

(f) Notwithstanding the obligations of CenterState in this Section 6.1 or anything in this Agreement to the contrary, in no event shall
CenterState be required in connection with obtaining any Requisite Regulatory Approval to (a) (i) maintain capital ratios greater than those set forth in Section 6.1(f)(i) of the CenterState Disclosure Schedule, (ii) maintain a
classified assets ratio lower than that set forth in Section 6.1(f)(ii) of the CenterState Disclosure Schedule, (iii) agree to originate any loans or make any payments to any one or more third parties other than pursuant to contracts or
commitments in effect as of the date hereof or as required or contemplated by this Agreement, (iv) raise common equity at the holding company or bank level in an amount that, or (v) agree to any strategic operational restriction, which, in
the case of each of subsections (i) through (v), would materially reduce the economic benefits of the Merger to the stockholders of CenterState following the Merger (including the stockholders of First Southern that receive CenterState Common
Stock in the Merger), (b) agree to any Loss Share Agreement Condition, or (c) agree to any other condition or restriction or take any action that would have a Material Adverse Effect on the Surviving Company and its Subsidiaries, taken as
a whole, after giving effect to the Merger (each of the foregoing referred to as a “Materially Burdensome Regulatory Condition”).

Party’s or its directors’, officers’, employees’, accountants’, counsel’s, advisors’ (including investment bankers), agents’ or other representatives’ consideration of, or deliberations regarding, the

cause its Board of Directors to, (i) take all action in accordance with the federal securities laws, the FBCA and the First Southern Charter and the First Southern Bylaws necessary to (A) call and give notice of a special meeting of First

the CenterState Board of Directors’ fiduciary duties, in which case it may omit the CenterState Board Recommendation from the Proxy Statement. Notwithstanding anything to the contrary contained in this Agreement, subject to the following
sentence, CenterState shall have an unqualified obligation to submit the issuance of CenterState Common Stock in connection with this Agreement and the Merger to a vote of its shareholders at the CenterState Shareholder Meeting. Notwithstanding

6.5 Employee Matters. 

(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 employed by First Southern and its Subsidiaries on the Closing Date (“Covered Employees”) that provide employee benefits and compensation opportunities which, in the aggregate, are substantially
comparable to the employee benefits and compensation opportunities that are made available to similarly situated employees of CenterState or its Subsidiaries, as applicable; provided, however, that in no event shall any Covered
Employee be eligible to participate in any closed or frozen plan of CenterState or its Subsidiaries. CenterState shall give the Covered Employees full credit for their prior service with First Southern and its Subsidiaries (i) for purposes of
eligibility (including initial participation and eligibility for current benefits) and vesting under any qualified or non-qualified employee benefit plan maintained by CenterState and in which Covered Employees may be eligible to participate and
(ii) for all purposes under any defined contribution retirement plans, welfare benefit plans, vacation plans, severance plans and similar arrangements maintained by CenterState. 

(b) With respect to any employee benefit plan of CenterState that is a health, dental, vision or other welfare plan in which any Covered
Employee is eligible to participate following the Closing Date, CenterState or its applicable Subsidiary shall (i) cause any pre-existing condition limitations or eligibility waiting periods under such CenterState or Subsidiary plan to be
waived with respect to such Covered Employee and his or her covered dependents to the extent such condition was or would have been covered under the First Southern 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 or his or her covered dependents in the year that includes the Closing Date for purposes of any applicable co-payment,
deductible or annual out-of-pocket expense requirements under any such health, dental, vision or other welfare plan. 
 (c) Prior to the
Effective Time, First Southern shall take, and shall cause its Subsidiaries to take, all actions requested by CenterState that may be necessary or appropriate to (i) cause the First Southern Benefits Plans set forth on Section 6.5(c) of
the First Southern Disclosure 

  
 49

Southern Benefit Plan for such period as may be requested by CenterState, or (iv) facilitate the merger of any such First Southern Benefit Plan into any employee benefit plan maintained by CenterState or an CenterState Subsidiary. All
resolutions, notices, or other documents issued, adopted or executed in connection with the implementation of this Section 6.5(c) shall be subject to CenterState’s reasonable prior review and approval, which shall not be unreasonably
withheld, conditioned or delayed. 
 (d) Nothing in this Section 6.5 shall be construed (i) to limit the right of CenterState or
any of its Subsidiaries (including, following the Closing Date, First Southern and its Subsidiaries) to amend or terminate any First Southern Benefit Plan or other employee benefit plan, to the extent such amendment or termination is permitted by
the terms of the applicable plan, (ii) to require CenterState or any of its Subsidiaries (including, following the Closing Date, First Southern and its Subsidiaries) to retain the employment of any particular Covered Employee for any fixed
period of time following the Closing Date, or (iii) to amend any First Southern Benefit Plan or other employee benefit plan, arrangement or agreement. 

(e) For purposes of this Agreement, “First Southern Benefit Plans” means any “employee benefit plan,” as defined in
Section 3(3) of ERISA, and all other benefit plans, arrangements or agreements, including any other employment, consulting, bonus, incentive or deferred compensation, vacation, stock option or other equity-based, severance, termination,
retention, change of control, profit-sharing, insurance, split dollar insurance, fringe benefit or other similar plan, program, agreement or commitment, whether written or unwritten, whether or not subject to ERISA, or whether formal or informal,
for the benefit of any employee, former employee, director or former director of First Southern or any of its Subsidiaries entered into, maintained or contributed to by First Southern or any of its Subsidiaries or to which First Southern or any of
its Subsidiaries is obligated to contribute, or with respect to which First Southern or any of its Subsidiaries has any liability, direct or indirect, contingent or otherwise, other than any Multiemployer Plan. 

(f) If, within twelve (12) months after the Effective Time, any Covered Employee is terminated by CenterState or its Subsidiaries other
than “for cause,” then CenterState shall pay severance to such Covered Employee in an amount equal to two weeks of base salary for each twelve months of such Covered Employee’s prior employment with First Southern or First Southern
Bank; provided, however, that in no event will the total amount of severance for any single Covered Employee be less than four weeks of such base salary nor greater than twenty-six weeks of such base salary. Any severance to which a
Covered Employee may be entitled in connection with a termination occurring more than twelve (12) months after the Effective Time will be as set forth in the severance policies of CenterState and its Subsidiaries as then in effect. 

(g) As of the date of this Agreement, First Southern has entered into agreements that terminate, at the Effective Time, the employment,
consulting, severance, change in control, or similar agreements or arrangements with the individuals set forth on Section 6.5(g) of the First Southern Disclosure Schedule with any confidentiality, noncompetition and nonsolicitation

  
 50 

 
provisions contained in such agreements and arrangements remaining in full force and effect following the Effective Time for a period of one year. The foregoing terminations shall be for payment
amounts not to exceed those set forth on Section 6.5(g) of the First Southern Disclosure Schedule. 
 (h) At the Effective Time, all
accrued and unused sick time for all employees of First Southern and its subsidiaries and relating to periods prior to January 1, 2014 shall terminate (without any payment therefor by First Southern and its Subsidiaries) and not carried over
to, or assumed by CenterState or its Subsidiaries. 
 6.6 Indemnification; Directors’ and Officers’ Insurance. 

(a) From and after the Effective Time, CenterState shall indemnify, defend and hold harmless the present and former directors, officers and
employees of First Southern and its Subsidiaries (the “Indemnified Parties”) against all costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages, settlements or liabilities as
incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative (each, a “Claim”), arising out of actions or omissions of such Persons in the course of
performing their duties for First Southern occurring at or before the Effective Time (including the transactions contemplated hereby), to the greatest extent as such persons are indemnified or have the right to advancement of expenses pursuant to
(i) the First Southern Charter, the First Southern Bylaws or the articles or certificate of incorporation or formation and bylaws (or comparable organizational documents) of First Southern’s Subsidiaries, each as in effect on the date of
this Agreement, and (ii) the FBCA. 
 (b) Any Indemnified Party wishing to claim indemnification under this Section 6.6 shall
promptly notify CenterState upon learning of any Claim, provided that failure to so notify shall not affect the obligation of CenterState under this Section 6.6 unless, and only to the extent that, CenterState is actually and materially
prejudiced in the defense of such Claim as a consequence. In the event of any such Claim (whether arising before or after the Effective Time), (i) CenterState shall have the right to assume the defense thereof and CenterState shall not be
liable to such Indemnified Parties for any legal expenses of other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof; provided, that CenterState shall not settle or
compromise or consent to the entry of any judgment in any such Claim unless such settlement, compromise or consent includes an unconditional release of such Indemnified Parties from all liability arising out of such Claim, (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 (not to be unreasonably withheld) and (iv) CenterState shall have no obligation
hereunder in the event that a federal or state banking agency or a court of competent jurisdiction shall determine that indemnification of an Indemnified Party in the manner contemplated hereby is prohibited by applicable laws and regulations. 

(c) For a period of six (6) years following the Effective Time, CenterState will provide director’s and officer’s liability
insurance (“D&O Insurance”) that serves to reimburse the present and former officers and directors of First Southern or its Subsidiaries (determined as of the Effective Time) with respect to claims against such directors and
officers arising from facts or events occurring at or before the Effective Time (including the transactions contemplated hereby), which insurance will contain at least the same coverage and amounts, and

  
 51 

 
contain terms and conditions no less advantageous to the Indemnified Party, as the coverage currently provided by First Southern; provided, however, that (i) if CenterState is
unable to maintain or obtain the insurance called for by this Section 6.6(c) then CenterState will provide as much comparable insurance as is reasonably available, (ii) officers and directors of First Southern or its Subsidiaries may be
required to make application and provide customary representations and warranties to the carrier of the D&O Insurance for the purpose of obtaining such insurance, and (iii) in satisfaction of its obligations under this Section 6.6(c),
CenterState may purchase, prior to but effective as of the Effective Time, tail insurance providing such coverage as described in this sentence. Whether or not CenterState shall procure such coverage, in no event shall CenterState be required to
expend for such tail insurance a premium amount in excess of an amount equal to 250% of the annual premiums paid by First Southern for D&O Insurance in effect as of the date of this Agreement (the “Maximum D&O Tail
Premium”). If the cost of such tail insurance exceeds the Maximum D&O Tail Premium, then CenterState shall obtain tail insurance coverage or a separate tail insurance policy with the greatest coverage available for a cost not exceeding
the Maximum D&O Tail Premium. 
 (d) If CenterState or any of its successors and assigns (i) shall consolidate with or merge into
any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) shall transfer all or substantially all of its property and assets to any individual, corporation or
other entity, then, in each such case, proper provision shall be made so that the successors and assigns of CenterState and its Subsidiaries shall assume the obligations set forth in this Section 6.6. The provisions of this Section 6.6
shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party and his or her heirs and representatives. 

6.7 No Solicitation. 

(a) First Southern agrees that, except as expressly permitted by Section 6.7(b), from the date of this Agreement until the Effective Time
or, if earlier, the termination of this Agreement in accordance with Section 8.1, it will not, and will cause its Subsidiaries and its and its Subsidiaries’ officers, directors, and employees (the “First Southern
Individuals”) not to, and will use its commercially reasonable best efforts to cause First Southern and its Subsidiaries’ agents, advisors, accountants, legal counsel, and financial advisors (the “First Southern
Representatives”) not to, initiate, solicit, knowingly encourage or knowingly facilitate inquiries or proposals with respect to, or engage in any discussions or negotiations concerning, or provide any confidential or nonpublic information
or data concerning its and its Subsidiaries’ business, properties or assets (“First Southern Confidential Information”) to, or have any discussions with, any Person relating to, any Acquisition Proposal. First Southern will
immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any Persons other than CenterState with respect to any Acquisition Proposal and will use its commercially
reasonable best efforts, subject to applicable law, to enforce any confidentiality or similar agreement relating to such an Acquisition Proposal. It is understood that any breach of the provisions of this Section 6.7 by any First Southern
Representative shall constitute a breach by First Southern. 
 (b) Notwithstanding anything to the contrary in Section 6.7(a), at any
time from the date of this Agreement and prior to obtaining the First Southern Shareholder Approval, in the event First Southern receives an unsolicited Acquisition Proposal and the Board of Directors

  
 52 

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

(c) Subject to the succeeding sentence, the Board of Directors of First Southern shall not (nor shall any committee thereof) withdraw or
modify, in a manner adverse to CenterState, the First Southern Board Recommendation or make or cause to be made any third party or public communication proposing or announcing an intention to withdraw or modify in any manner adverse to CenterState
the First Southern Board Recommendation (any such action, a “Change in Recommendation”). Notwithstanding the foregoing, if the First Southern Board concludes in good faith (after consultation with its outside legal and financial
advisors) that an Acquisition Proposal constitutes a Superior Proposal and (after consultation with its legal advisors) that failure to do so could be inconsistent with its fiduciary obligations to the stockholders of First Southern under applicable
laws, the First Southern Board of Directors may at any time prior to the First Southern Shareholder Approval (i) effect a Change in Recommendation or (ii) terminate this Agreement to enter into a definitive agreement with respect to such
Superior Proposal; provided, however, that the Board of Directors of First Southern may not make a Change in Recommendation, or terminate this Agreement, with respect to an Acquisition Proposal unless (i) First Southern shall not
have breached this Section 6.7 in any material respect and (ii) (A) the Board of Directors of First Southern determines in good faith (after consultation with counsel) that such Superior Proposal has been made and has not been
withdrawn and continues to be a Superior Proposal after taking into account all adjustments to the terms of this Agreement that may be offered by CenterState under this Section 6.7(c); (B) First Southern has given CenterState at least
three (3) days’ prior written notice of its intention to take such action set forth above (which notice shall specify the material terms and conditions of any such Superior Proposal (including the identity of the Person making such
Superior Proposal) and has contemporaneously provided an unredacted copy of the relevant proposed transaction agreements with the Person making such Superior Proposal; and (C) before effecting such Change in Recommendation, First Southern has
negotiated, and has caused its representatives to negotiate, in good faith with CenterState during such notice period to the extent CenterState wishes to negotiate, to enable CenterState to revise the terms of this Agreement such that it would cause
such Superior Proposal to no longer constitute a Superior Proposal. In the event of any material change to the terms of such Superior Proposal, First Southern shall, in each case, be required to deliver to CenterState a new written notice, the
notice period shall have recommenced and First Southern shall be required to comply with its obligations under this Section 6.7 with respect to such new written notice. 

  
 53 

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

legal (with the advice of outside counsel), financial (including the financing terms of any such proposal), regulatory and other aspects of such proposal and any other relevant factors permitted under applicable law; provided, however,
that for purposes of the definition of “Superior Proposal,” the references to twenty percent (20%) in the definition of Acquisition Proposal shall be deemed to be references to fifty percent (50%). 

6.8 Notification of Certain Matters. Each of the Parties shall give prompt written notice to the other of any fact, event or

a material breach of any of its representations, warranties, covenants or agreements contained herein; provided, that any failure to give such notice in accordance with the foregoing with respect to any breach shall not be deemed to
constitute a violation of this Section 6.8 or the failure of a condition contained in Article VII unless the underlying breach would independently result in a failure of a condition set forth in Article VII. Each of the Parties shall promptly
inform the other in writing upon receiving notice of any material Action by any Governmental Entity or third party against, or threatened against, it or any of its Subsidiaries or any of their respective assets, properties, or any of their
respective directors, officers or employees in their individual capacities as such.

relating to the development, coordination and implementation of the post-Merger operating and integration plans of CenterState Bank of Florida, N.A., as the resulting institution in the Bank Merger; provided, however, that,

income tax purposes.

obligation to complete the Merger cannot be fulfilled and that it will not waive that condition, it will promptly notify the other Party. 

6.15 Corporate Governance. At or prior to the Effective Time, CenterState, if it so elects, may cause one member of the Board of
Directors of First Southern or First Southern Bank to be determined by CenterState, to be appointed to the Boards of Directors of the Surviving Company and CenterState Bank of Florida, N.A., effective as of the Effective Time.

has denied approval of the Merger or the Bank Merger and such denial has become final and nonappealable or any Governmental Entity of competent jurisdiction shall have issued a final and nonappealable order, injunction or decree permanently
enjoining or otherwise prohibiting or making illegal the consummation of the Merger or the Bank Merger; provided, however, that a Party shall not be permitted to terminate this Agreement pursuant to this Section 8.1(a)(ii) if such

(iii) by either First Southern or CenterState, if the Merger shall not have been consummated on or before 270 days following the date of this
Agreement, unless the failure of the Closing to occur by such date shall be due to the failure of the Party seeking to terminate this Agreement to perform or observe the covenants and agreements of such Party set forth in this Agreement; 

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

obligation under Section 8.4(a); 

  
 60 

 (vii) by either First Southern or CenterState, if the shareholders of First Southern fail to
provide the First Southern Shareholder Approval at a duly held meeting of shareholders or at an adjournment or postponement thereof; 

(viii) by First Southern if the Board of Directors of CenterState (or any committee thereof) shall have failed to make the CenterState Board

definitive agreement with respect to such Acquisition Proposal or consummating such Acquisition Proposal, pay CenterState the Termination Fee by wire transfer of same-day funds. For purposes of the immediately preceding clauses (i) and (ii),
the references to twenty percent (20%) in the definition of Acquisition Proposal shall be deemed to be references to fifty percent (50%). 

(c) If this Agreement is terminated (i) by First Southern pursuant to Section 8.1(a)(viii), or (ii) by First Southern pursuant
to Section 8.1(a)(iv) following a material breach by CenterState of any of the provisions of Section 6.1 (which for the avoidance of doubt shall not be deemed to include a failure to comply with the provisions therein that provide for a
specific filing deadline with respect to applications or filings with Governmental Entities), CenterState shall, within three (3) Business Days after such termination, pay First Southern the Termination Fee by wire transfer of same-day funds.

 (d) Notwithstanding anything to the contrary in this Agreement, other than in the case of a willful and material breach of this
Agreement, the payment of the Termination Fee pursuant to this Section 8.4 shall fully discharge the Party paying such Termination Fee from, and be the sole and exclusive remedy of the other Party with respect to, any and all losses that may be
suffered by such other Party based upon, resulting from or arising out of the circumstances giving rise to such termination of this Agreement. In no event shall First Southern or CenterState be required to pay the Termination Fee on more than one
occasion. 
 (e) The Parties agree that the agreements contained in this Section 8.4 are an integral part of the transactions
contemplated by this Agreement, and that, without these agreements, the Parties would not enter into this Agreement. 

  
 63 

 8.5 Amendment. This Agreement may be amended by the Parties, by action taken or authorized
by their respective Boards of Directors, at any time before or after approval of the matters presented in connection with this Agreement by the shareholders of First Southern or CenterState; provided, however, that after any approval
of the transactions contemplated by this Agreement by the shareholders of First Southern or CenterState, there may not be, without further approval of such shareholders, any amendment of this Agreement that requires further approval under applicable
law. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the Parties. 
 8.6 Extension;
Waiver. At any time prior to the Effective Time, the Parties, by action taken or authorized by their respective Board of Directors, may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or
other acts of the other Party, (b) waive any inaccuracies in the representations and warranties contained in this Agreement on the part of the other Party or (c) waive compliance with any of the agreements or conditions contained in this
Agreement on the part of the other Party. Any agreement on the part of a Party to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such Party, but such extension or waiver or failure to insist
on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

 EXHIBIT A 

SHAREHOLDER VOTING AGREEMENT 

This Shareholder Voting Agreement (this “Agreement”) is entered into as of the 29th day of January, 2014, by and between
CenterState Banks, Inc., a Florida corporation (“CenterState”), and the undersigned holder (“Shareholder”) of Common Stock (as defined herein). 

RECITALS 
 WHEREAS,
as of the date hereof, Shareholder “beneficially owns” (as such term is defined in Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended) and is entitled to dispose of (or to direct the disposition of) and to vote
(or to direct the voting of) the number of shares of voting common stock, $0.01 par value per share (the “Common Stock”), of First Southern Bancorp, Inc. (“First Southern”), indicated on the signature page of this
Agreement under the heading “Total Number of Shares of Common Stock Subject to this Agreement” (such shares of Common Stock, which for the avoidance of doubt shall not include any shares of Common Stock underlying First Southern Stock
Options) together with any other shares of Common Stock the voting power over which is acquired by Shareholder during the period from and including the date hereof through and including the date on which this Agreement is terminated in accordance
with its terms, are collectively referred to herein as the “Shares”); 
 WHEREAS, CenterState and First Southern
propose to enter into an Agreement and Plan of Merger, dated as of the date hereof (the “Merger Agreement”; for purposes of this Agreement, capitalized terms used and not otherwise defined herein shall have the respective meanings
ascribed to them in the Merger Agreement), pursuant to which, among other things, First Southern will merge with and into CenterState (the “Merger”); and 

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

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

1. Agreement to Vote Shares. Shareholder agrees that, while this Agreement is in effect, at any meeting of shareholders of First
Southern, however called, or at any adjournment thereof, or in any other circumstances in which Shareholder is entitled to vote, consent or give any other approval, except as otherwise agreed to in writing in advance by CenterState, Shareholder
shall: 
 (a) appear at each such meeting or otherwise cause the Shares to be counted as present thereat for purposes of calculating a
quorum; and 
 (b) vote (or cause to be voted), in person or by proxy, all the Shares as to which Shareholder has, directly or indirectly,
the right to vote or direct the voting, (i) in favor of adoption and approval of the Merger Agreement and the transactions contemplated thereby (including, 

  
 A-1 

 
without limitation, any amendments or modifications of the terms thereof adopted in accordance with the terms thereof); (ii) against any action or agreement that would result in a breach of
any covenant, representation or warranty or any other obligation or agreement of First Southern contained in the Merger Agreement or of Shareholder contained in this Agreement; and (iii) against any Acquisition Proposal or any other action,
agreement or transaction that is intended, or could reasonably be expected, to impede, interfere or be inconsistent with, delay, postpone, discourage or materially and adversely affect consummation of the transactions contemplated by the Merger
Agreement or this Agreement. 
 Shareholder further agrees not to vote or execute any written consent to rescind or amend in any manner any
prior vote or written consent, as a shareholder of First Southern, to approve or adopt the Merger Agreement unless this Agreement shall have been terminated in accordance with its terms. 

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

3. Representations and Warranties of Shareholder. Shareholder represents and warrants to and agrees with CenterState as follows:
 
 (a) Shareholder has all requisite capacity and authority to enter into and perform his, her or its obligations under this
Agreement. 
 (b) This Agreement has been duly executed and delivered by Shareholder, and assuming the due authorization, execution and
delivery by CenterState, constitutes the valid and legally binding obligation of Shareholder enforceable against Shareholder in accordance with its terms, except as may be limited by bankruptcy, insolvency, fraudulent transfer, moratorium,
reorganization or similar laws of general applicability relating to or affecting the rights of creditors generally and subject to general principles of equity. 

(c) The execution and delivery of this Agreement by Shareholder does not, and the performance by Shareholder of his, her or its obligations
hereunder and the consummation by Shareholder of the transactions contemplated hereby will not, violate or conflict with, or constitute a default under, any agreement, instrument, contract or other obligation or any order,

  
 A-2 

 
arbitration award, judgment or decree to which Shareholder is a party or by which Shareholder is bound, or any statute, rule or regulation to which Shareholder is subject or, in the event that
Shareholder is a corporation, limited liability company, partnership, trust or other entity, any charter, bylaw or other organizational document of Shareholder. 

(d) Shareholder is the beneficial owner of the Shares. Shareholder does not own, of record or beneficially, any shares of capital stock of
First Southern other than the Shares or any other securities convertible into or exercisable or exchangeable for such capital stock, other than any First Southern Stock Options. Shareholder has the right to vote the Shares, and none of the Shares is
subject to any voting trust or other agreement, arrangement or restriction with respect to the voting of the Shares, except as contemplated by this Agreement or provided by the FBCA. 

4. No Solicitation. From and after the date hereof until the termination of this Agreement pursuant to Section 7 hereof,
Shareholder, in his, her or its capacity as a shareholder of First Southern, shall not, nor shall Shareholder authorize any shareholder, member, partner, officer, director, advisor or representative of Shareholder or any of his, her or its
affiliates to (and, to the extent applicable to Shareholder, such Shareholder shall use commercially reasonable efforts to not permit any of his, her or its representatives or affiliates to), (a) initiate, solicit, induce or knowingly
encourage, or knowingly take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an Acquisition Proposal, (b) participate in any discussions or negotiations
regarding any Acquisition Proposal, or furnish, or otherwise afford access, to any person (other than CenterState) any information or data with respect to First Southern or otherwise relating to an Acquisition Proposal, (c) enter into any
agreement, agreement in principle, letter of intent, memorandum of understanding or similar arrangement with respect to an Acquisition Proposal, (d) solicit proxies with respect to an Acquisition Proposal (other than the Merger and the Merger
Agreement) or otherwise encourage or assist any party in taking or planning any action that would compete with, restrain or otherwise serve to interfere with or inhibit the timely consummation of the Merger in accordance with the terms of the Merger
Agreement, or (e) initiate a shareholders’ vote or action by consent of First Southern’s shareholders with respect to an Acquisition Proposal, in each case, except to the extent that at such time First Southern is permitted to take
such action pursuant to Section 6.7 of the Merger Agreement. For avoidance of doubt, the parties acknowledge and agree that nothing in this Agreement shall limit or restrict Shareholder or any of his, her or its affiliates who is or becomes
during the term hereof a member of the Board of Directors or an officer of First Southern or any of its Subsidiaries from acting, omitting to act or refraining from taking any action, solely in such person’s capacity as a member of the Board of
Directors or as an officer of First Southern (or as an officer or director of any of its Subsidiaries), including without limitation actions taken consistent with his or her fiduciary duties in such capacity under applicable law. 

5. Proxy. Subject to the last sentence of this Section 5, by execution of this Agreement, Shareholder does hereby appoint
CenterState with full power of substitution and resubstitution, as Shareholder’s true and lawful attorney and proxy, to the full extent of Shareholder’s rights with respect to the Shares, to vote each of such Shares that Shareholder shall
be entitled to so vote with respect to the matters set forth in Section 1 hereof at any meeting of the shareholders of First Southern, and at any adjournment or postponement thereof, and in connection with

  
 A-3 

 
any action of the shareholders of First Southern taken by written consent. Shareholder hereby revokes any proxy previously granted by Shareholder with respect to the Shares. Notwithstanding
anything contained herein to the contrary, this proxy shall automatically terminate and be revoked upon the termination of this Agreement. 

6. Specific Performance; Remedies; Attorneys’ Fees. Shareholder acknowledges that it is a condition to the willingness of
CenterState to enter into the Merger Agreement that Shareholder execute and deliver this Agreement and that it will be impossible to measure in money the damage to CenterState if Shareholder fails to comply with the obligations imposed by this
Agreement and that, in the event of any such failure, CenterState will not have an adequate remedy at law or in equity. Accordingly, Shareholder agrees that injunctive relief or other equitable remedy is the appropriate remedy for any such failure
and will not oppose the granting of such relief on the basis that CenterState has an adequate remedy at law. In addition, CenterState shall have the right to inform any third party that CenterState reasonably believes to be, or to be contemplating,
participating with Shareholder or receiving from Shareholder assistance in violation of this Agreement, of the terms of this Agreement and of the rights of CenterState hereunder, and that participation by any such thirty party with Shareholder in
activities in violation of Shareholder’s agreement with CenterState set forth in this Agreement may give rise to claims by CenterState against such third party. In any legal action or other proceeding relating to this Agreement and the
transactions contemplated hereby or if the enforcement of any provision of this Agreement is brought against either Party, the prevailing Party in such action or proceeding shall be entitled to recover all reasonable expenses relating thereto
(including reasonable attorneys’ fees and expenses, court costs and expenses incident to arbitration, appellate and post-judgment proceedings) from the Party against which such action or proceeding is brought, in addition to any other relief to
which such prevailing Party may be entitled. 
 7. Term of Agreement; Termination. The term of this Agreement shall
commence on the date hereof. This Agreement may be terminated at any time prior to consummation of the transactions contemplated by the Merger Agreement by the written consent of the parties hereto, and this Agreement shall be automatically
terminated upon termination of the Merger Agreement or the consummation of the Merger. Upon such termination, no party shall have any further obligations or liabilities hereunder; provided, however, that such termination shall not
relieve any party from liability for any willful and material breach of this Agreement prior to such termination.  
 8.
Entire Agreement; Amendments. This Agreement supersedes all prior agreements, written or oral, among the parties hereto with respect to the subject matter hereof and contains the entire agreement among the parties with respect to the subject
matter hereof. This Agreement may not be amended, supplemented or modified, and no provision hereof may be modified or waived, except by an instrument in writing signed by each party hereto. No waiver of any provision hereof by either party shall be
deemed a waiver of any other provision hereof by any such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party.  

9. Severability. In the event that any one or more provisions of this Agreement shall for any reason be held invalid, illegal or
unenforceable in any respect by any court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provisions of this Agreement, and the parties shall use their reasonable best efforts to substitute a
valid, legal and enforceable provision which, insofar as practical, implements the purpose and intents of this Agreement. 

  
 A-4 

 10. Capacity as Shareholder. This Agreement shall apply to Shareholder solely in
his, her or its capacity as a shareholder of First Southern, and it shall not apply in any manner to Shareholder in any capacity as a director, officer or employee of First Southern or its Subsidiaries or in any other capacity, and shall not limit
or affect any actions taken by Shareholder in such capacity. 
 11. Governing Law. This Agreement shall be governed and
construed in accordance with the laws of the State of Florida, without regard to any applicable conflicts of law principles or any other principle that could require the application of the law of any other jurisdiction.  

12. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW
ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF THE
PARTIES IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT. EACH OF THE PARTIES HERETO (A) CERTIFIES THAT NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY BY, AMONG OTHER THINGS, THE
MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 12. 
 13. Waiver of Appraisal Rights; Further Assurances. To the
extent permitted by applicable law, Shareholder hereby waives any rights of appraisal or rights to dissent from the Merger or to demand fair value for his, her or its Shares in connection with the Merger, in each case, that Shareholder may have
under applicable law. Shareholder further agrees not to commence or participate in, and to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against CenterState, First
Southern or any of their respective successors relating to the negotiation, execution or delivery of this Agreement or the Merger Agreement or the consummation of the Merger. From time to time prior to the termination of this Agreement, at
CenterState’s request and without further consideration, Shareholder shall execute and deliver such additional documents and take all such further action as may be reasonably necessary or desirable to effect the actions and consummate the
transactions contemplated by this Agreement.  
 14. Disclosure. Shareholder hereby permits CenterState and First Southern to
publish and disclose in the Proxy Statement and Form S-4 (including, without limitation, all related documents and schedules filed with the Securities and Exchange Commission) his, her or its identity and ownership of shares of Common Stock and the
nature of Shareholder’s commitments, arrangements and understandings pursuant to this Agreement. 

  
 A-5 

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

WHEREAS, as a condition to the willingness of First Southern to enter into the Merger Agreement, Shareholder is executing this
Agreement; 
 NOW, THEREFORE, in consideration of, and as a material inducement to, First Southern entering into the Merger Agreement
and proceeding with the transactions contemplated thereby, and in consideration of the expenses incurred and to be incurred by First Southern in connection therewith, Shareholder and First Southern, intending to be legally bound, hereby agree as
follows: 
 1. Agreement to Vote Shares. Shareholder agrees that, while this Agreement is in effect, at any meeting of shareholders
of CenterState, however called, or at any adjournment thereof, or in any other circumstances in which Shareholder is entitled to vote, consent or give any other approval, except as otherwise agreed to in writing in advance by First Southern,
Shareholder shall: 
 (a) appear at each such meeting or otherwise cause the Shares to be counted as present thereat for purposes of
calculating a quorum; and 
 (b) vote (or cause to be voted), in person or by proxy, all the Shares as to which Shareholder has, directly or
indirectly, the right to vote or direct the voting, (i) in favor of 

  
 B-1 

 
the issuance of Common Stock in connection with the Merger and the other transactions contemplated by the Merger Agreement (“the Stock Issuance”); (ii) against any action or
agreement that would result in a breach of any covenant, representation or warranty or any other obligation or agreement of CenterState contained in the Merger Agreement or of Shareholder contained in this Agreement; and (iii) against any
action, agreement or transaction that is intended, or could reasonably be expected, to impede, interfere or be inconsistent with, delay, postpone, discourage or materially and adversely affect consummation of the Merger, the Stock Issuance or the
other transactions contemplated by the Merger Agreement or this Agreement. 
 Shareholder further agrees not to vote or execute any written
consent to rescind or amend in any manner any prior vote or written consent, as a shareholder of CenterState, to approve the Stock Issuance unless this Agreement shall have been terminated in accordance with its terms. 

2. No Transfers. While this Agreement is in effect, Shareholder agrees not to, directly or indirectly, sell, transfer, pledge, assign
or otherwise dispose of, or enter into any contract option, commitment or other arrangement or understanding with respect to the sale, transfer, pledge, assignment or other disposition of, any of the Shares; provided, however, that the
following transfers shall be permitted: (a) transfers by will or operation of law, in which case this Agreement shall bind the transferee; (b) transfers pursuant to any pledge agreement, subject to the pledgee agreeing in writing, prior to
such transfer, to be bound by the terms of this Agreement; (c) transfers in connection with estate and tax planning purposes, including transfers to relatives, trusts and charitable organizations, subject to each transferee agreeing in writing,
prior to such transfer, to be bound by the terms of this Agreement; (d) disposing of or surrendering Shares in connection with the vesting, settlement or exercise of CenterState stock options or restricted shares of Common Stock for the payment
of taxes thereon or, in the case of CenterState stock options, the exercise price; and (e) such transfers as First Southern may otherwise permit in its sole discretion. Any transfer or other disposition in violation of the terms of this
Section 2 shall be null and void. 
 3. Representations and Warranties of Shareholder. Shareholder represents and warrants to
and agrees with First Southern as follows: 
 (a) Shareholder has all requisite capacity and authority to enter into and perform his, her or
its obligations under this Agreement. 
 (b) This Agreement has been duly executed and delivered by Shareholder, and assuming the due
authorization, execution and delivery by First Southern, constitutes the valid and legally binding obligation of Shareholder enforceable against Shareholder in accordance with its terms, except as may be limited by bankruptcy, insolvency, fraudulent
transfer, moratorium, reorganization or similar laws of general applicability relating to or affecting the rights of creditors generally and subject to general principles of equity. 

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

  
 B-2 

 (d) Shareholder is the beneficial owner of the Shares. Shareholder does not own, of record or
beneficially, any shares of capital stock of CenterState other than the Shares or any other securities convertible into or exercisable or exchangeable for such capital stock, other than any CenterState stock options. Shareholder has the right to
vote the Shares, and none of the Shares is subject to any voting trust or other agreement, arrangement or restriction with respect to the voting of the Shares, except as contemplated by this Agreement or provided by the FBCA. 

4. Prohibited Actions. From and after the date hereof until the termination of this Agreement pursuant to Section 7 hereof,
Shareholder, in his, her or its capacity as a shareholder of CenterState, shall not, nor shall Shareholder authorize any shareholder, member, partner, officer, director, advisor or representative of Shareholder or any of his, her or its affiliates
to (and, to the extent applicable to Shareholder, such Shareholder shall use commercially reasonable efforts to not permit any of his, her or its representatives or affiliates to) encourage or assist any party in taking or planning any action that
would compete with, restrain or otherwise serve to interfere with or inhibit the timely consummation of the Merger in accordance with the terms of the Merger Agreement. For avoidance of doubt, the parties acknowledge and agree that nothing in this
Agreement shall limit or restrict Shareholder or any of his, her or its affiliates who is or becomes during the term hereof a member of the Board of Directors or an officer of CenterState or any of its Subsidiaries from acting, omitting to act or
refraining from taking any action, solely in such person’s capacity as a member of the Board of Directors or as an officer of CenterState (or as an officer or director of any of its Subsidiaries), including without limitation actions taken
consistent with his or her fiduciary duties in such capacity under applicable law. 
 5. Proxy. Subject to the last sentence of this
Section 5, by execution of this Agreement, Shareholder does hereby appoint First Southern with full power of substitution and resubstitution, as Shareholder’s true and lawful attorney and proxy, to the full extent of Shareholder’s
rights with respect to the Shares, to vote each of such Shares that Shareholder shall be entitled to so vote with respect to the matters set forth in Section 1 hereof at any meeting of the shareholders of CenterState, and at any adjournment or
postponement thereof, and in connection with any action of the shareholders of CenterState taken by written consent. Shareholder hereby revokes any proxy previously granted by Shareholder with respect to the Shares. Notwithstanding anything
contained herein to the contrary, this proxy shall automatically terminate and be revoked upon the termination of this Agreement. 
 6.
Specific Performance; Remedies; Attorneys’ Fees. Shareholder acknowledges that it is a condition to the willingness of First Southern to enter into the Merger Agreement that Shareholder execute and deliver this Agreement and that it will
be impossible to measure in money the damage to First Southern if Shareholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, First Southern will not have an adequate remedy at law or in
equity. Accordingly, Shareholder agrees that injunctive relief or other equitable remedy is the appropriate remedy for any such failure and will not oppose the granting of such relief on the basis that First Southern has an adequate remedy at law.
In addition, First Southern shall have the right to inform any third party that First Southern reasonably believes to be, or to be contemplating, participating with Shareholder or receiving from Shareholder assistance in violation of this Agreement,
of the terms of this Agreement and of the rights of First 

  
 B-3 

 
Southern hereunder, and that participation by any such thirty party with Shareholder in activities in violation of Shareholder’s agreement with First Southern set forth in this Agreement may
give rise to claims by First Southern against such third party. In any legal action or other proceeding relating to this Agreement and the transactions contemplated hereby or if the enforcement of any provision of this Agreement is brought against
either Party, the prevailing Party in such action or proceeding shall be entitled to recover all reasonable expenses relating thereto (including reasonable attorneys’ fees and expenses, court costs and expenses incident to arbitration,
appellate and post-judgment proceedings) from the Party against which such action or proceeding is brought, in addition to any other relief to which such prevailing Party may be entitled. 

7. Term of Agreement; Termination. The term of this Agreement shall commence on the date hereof. This Agreement may be terminated at
any time prior to consummation of the transactions contemplated by the Merger Agreement by the written consent of the parties hereto, and this Agreement shall be automatically terminated upon termination of the Merger Agreement or the consummation
of the Merger. Upon such termination, no party shall have any further obligations or liabilities hereunder; provided, however, that such termination shall not relieve any party from liability for any willful and material breach of this
Agreement prior to such termination. 
 8. Entire Agreement; Amendments. This Agreement supersedes all prior agreements, written or
oral, among the parties hereto with respect to the subject matter hereof and contains the entire agreement among the parties with respect to the subject matter hereof. This Agreement may not be amended, supplemented or modified, and no provision
hereof may be modified or waived, except by an instrument in writing signed by each party hereto. No waiver of any provision hereof by either party shall be deemed a waiver of any other provision hereof by any such party, nor shall any such waiver
be deemed a continuing waiver of any provision hereof by such party. 
 9. Severability. In the event that any one or more provisions
of this Agreement shall for any reason be held invalid, illegal or unenforceable in any respect by any court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provisions of this Agreement, and the
parties shall use their reasonable best efforts to substitute a valid, legal and enforceable provision which, insofar as practical, implements the purpose and intents of this Agreement. 

10. Capacity as Shareholder. This Agreement shall apply to Shareholder solely in his, her or its capacity as a shareholder of
CenterState, and it shall not apply in any manner to Shareholder in any capacity as a director, officer or employee of CenterState or its Subsidiaries or in any other capacity, and shall not limit or affect any actions taken by Shareholder in such
capacity. 
 11. Governing Law. This Agreement shall be governed and construed in accordance with the laws of the State of Florida,
without regard to any applicable conflicts of law principles or any other principle that could require the application of the law of any other jurisdiction. 

12. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ALL
RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR 

  
 B-4 

 
COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF THE
PARTIES IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT. EACH OF THE PARTIES HERETO (A) CERTIFIES THAT NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY BY, AMONG OTHER THINGS, THE
MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 12. 
 13. Waiver of Appraisal Rights; Further Assurances. To the extent permitted
by applicable law, Shareholder hereby waives any rights of appraisal or rights to dissent from the Merger or to demand fair value for his, her or its Shares in connection with the Merger, in each case, that Shareholder may have under applicable law.
Shareholder further agrees not to commence or participate in, and to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against CenterState, First Southern or any of their
respective successors relating to the negotiation, execution or delivery of this Agreement or the Merger Agreement or the consummation of the Merger. From time to time prior to the termination of this Agreement, at First Southern’s request and
without further consideration, Shareholder shall execute and deliver such additional documents and take all such further action as may be reasonably necessary or desirable to effect the actions and consummate the transactions contemplated by this
Agreement. 
 14. Disclosure. Shareholder hereby permits First Southern and CenterState to publish and disclose in the Proxy
Statement and Form S-4 (including, without limitation, all related documents and schedules filed with the Securities and Exchange Commission) his, her or its identity and ownership of shares of Common Stock and the nature of Shareholder’s
commitments, arrangements and understandings pursuant to this Agreement. 
 15. Counterparts. This Agreement may be executed in
counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. Executed counterparts may be delivered by facsimile or other electronic transmission.

No waiver, amendment, modification or change of any provision of this Agreement shall be effective unless and until made in writing and signed

waiver by such Bank of compliance with any provision hereof. 
 Except to the extent Federal law is applicable hereto, this Agreement shall
be governed by and construed and enforced in accordance with the Laws of the State of Florida without regard to principles of conflicts of laws. 

This Agreement will be binding upon, inure to the benefit of, and be enforceable by, the Banks’ respective successors and permitted
assigns. 
 Unless otherwise expressly stated herein, this Agreement shall not benefit or create any right of action in or on behalf of any

and pursuant to the transactions contemplated by the Merger Agreement, Director is expected to receive significant consideration in exchange for the shares of First Southern Common Stock (as defined in the Merger Agreement) held by Director; 

WHEREAS, prior to the date hereof, Director has served as a member of the Board of Directors of First Southern, and, therefore,
Director has knowledge of the Confidential Information (as hereinafter defined); and 
 WHEREAS, as a result of the Merger,
CenterState will succeed to all of the Confidential Information, 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 First Southern, 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. 

  
 D-1 

 (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 for purposes of engaging in a Competitive Activity any Confidential Information for so long as such information remains Confidential Information, except for any disclosure that is required by applicable law or court order. In the
event that Director is required by law or court order to disclose any Confidential Information, Director will: (i) if and to the extent permitted by such law or court order provide CenterState with prompt notice of such requirement prior to the
disclosure so that CenterState may waive the requirements of this Agreement or seek an appropriate protective order at CenterState’s sole expense; and (ii) use commercially reasonable efforts to obtain assurances that any Confidential
Information disclosed will be accorded confidential treatment. If, in the absence of a waiver or protective order, Director is nonetheless, in the opinion of his counsel, required to disclose Confidential Information, disclosure may be made only as
to that portion of the Confidential Information that counsel advises Director is required to be disclosed. 
 (ii) Except as
expressly provided on Schedule I to this Agreement, for a period beginning at the Effective Time and ending two (2) years after the Effective Time, Director will not (except on behalf of or with the prior written consent of CenterState), on
Director’s own behalf or in the service or on behalf of others, solicit or attempt to solicit any customer of CenterState, CenterState Bank, N.A., First Southern or First Southern Bank (each a “Protected Party”), including
actively sought prospective customers of First Southern Bank as of the Effective Time, for the purpose of engaging in any Competitive Activity (as hereinafter defined). 

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

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

(i) “Competitive Activity” means the business of providing retail or commercial banking services through bank
branches located in the Restricted Territory. 

  
 D-2 

 (ii) “Confidential Information” shall mean all non-public data
and information: 
 (A) relating to the business of First Southern and its subsidiaries, including First Southern Bank; 

(B) disclosed to Director or of which Director became aware as a consequence of Director’s relationship with First
Southern as a director; 
 (C) having value to First Southern and, as a result of the consummation of the transactions
contemplated by the Merger Agreement, CenterState; and 
 (D) not generally known to competitors of First Southern or
CenterState. 
 Confidential Information shall include non-public methods of operation, names of customers, price lists, financial
information and projections, personnel data and similar non-public information; provided, however, that the term “Confidential Information” 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 First Southern 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 Palm Beach, Broward, Orange, Saint Johns, Osceola,
Seminole, Volusia and Duval Counties in Florida. 
 (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 (i) termination of the Merger Agreement or (ii) two (2) years following the Effective Time. 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 two (2) years after the Effective Time. Upon termination of this Agreement, no party shall have any further obligations or liabilities
hereunder; provided, however, that such termination shall not relieve any party from liability for any willful and material breach of this Agreement prior to such termination. 

  
 D-3 

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

 WHEREAS, in recognition of the need to provide Indemnitee with substantial protection against personal
liability, in order to procure Indemnitee’s service or continued service to the Company and to enhance Indemnitee’s ability to serve the Company in an effective manner, and in order to provide such protection pursuant to express contract

(d) with respect to any Claim initiated by Indemnitee without the prior written consent or authorization of the Board of Directors of the
Company, provided that this exclusion shall not apply with respect to any Claim brought by Indemnitee to enforce any provision of this Agreement, whether by claim, cross claim, or counterclaim in a legal proceeding, arbitration or otherwise where

3. Advancement of Expenses. Prior to the final disposition of any Indemnifiable Claim and without regard to Indemnitee’s ultimate entitlement to

reimburse Indemnitee for any and all Expenses relating to, arising out of or resulting from such Indemnifiable Claim paid or incurred by Indemnitee; provided, that the Company shall have no obligation to advance Expenses incurred by
Indemnitee with respect to any Claim initiated by Indemnitee (other than a Claim brought by Indemnitee to enforce any provision of this Agreement); and provided further, that Indemnitee shall execute and deliver to the Company an unsecured
undertaking by or on behalf of Indemnitee to repay any amounts paid, advanced or reimbursed by the Company hereunder unless it shall ultimately be determined that Indemnitee is entitled to indemnification. Indemnitee shall promptly repay, without
interest, any amounts actually advanced to Indemnitee that, at the final disposition of the Indemnifiable Claim to which the advance related, were in excess of amounts paid or payable by Indemnitee in respect of Expenses relating to, arising out of
or resulting from such Indemnifiable Claim. The Company shall advance, pay or reimburse Expenses pursuant to this Section 3 within thirty (30) calendar days of its receipt of a written request from Indemnitee accompanied by reasonable
documentation evidencing the amount or nature of the Expenses, subject to the Company’s prior receipt of a written request pursuant to Section 4 and the undertaking referenced in this Section 3. 

4. Procedure for Indemnification. To obtain indemnification or advancement of expenses under this Agreement, Indemnitee shall submit to the Company a
written request therefor, including a brief description (based upon information then available to Indemnitee) of such Indemnifiable Claim or Indemnifiable Loss. 

5. Determination That Indemnification Is Proper. 

(a) To the extent that Indemnitee has been wholly successful, on the merits or otherwise, in the defense of any Indemnifiable Claim, Indemnitee
shall be indemnified against all Indemnifiable Losses relating to, arising out of or resulting from such Indemnifiable Claim in accordance with Section 2 and no Standard of Conduct Determination (as defined in Section 5(b)) shall
be required. 
 (b) To the extent that the provisions of Section 5(a) are inapplicable to an Indemnifiable Claim or part thereof that
shall have been finally disposed of, or if any Indemnifiable Claim is concluded without a final adjudication on the issue of liability, the Company shall, subject to the provisions of 

  
 4 

 
Sections 2(a)–2(e), nevertheless indemnify Indemnitee for Indemnifiable Losses unless a determination is made that indemnification of Indemnitee is not proper in the circumstances because
his or her actions in question were, at the time taken, known or believed by him or her to be clearly in conflict with the best interests of the Company (and/or, if applicable, in conflict with in the best interests of the Constituent Enterprise) or
otherwise failed to satisfy the applicable standard of conduct for indemnification under North Carolina law (a determination of whether or not such actions were so known or believed or otherwise failed to satisfy the foregoing standard shall be a
“Standard of Conduct Determination”). In making the Standard of Conduct Determination, the knowledge and/or actions, or failure to act, of any other director, officer, partner, member, trustee, employee or agent of the Company or
any entity or other enterprise of which Indemnitee, at the request of the Company, is or was serving or agreed to serve as a director officer, partner, member, trustee, employee or agent shall not be imputed to Indemnitee for purposes of determining
his or her right to indemnification under this Agreement. Any Standard of Conduct Determination shall be made in accordance with this paragraph. If a Change in Control shall not have occurred, or if a Change in Control shall have occurred but
Indemnitee shall have requested that the Standard of Conduct Determination be made pursuant to this sentence, the Standard of Conduct Determination shall be made either (1) by the Board of Directors of the Company by majority vote of a quorum
consisting of directors not at the time parties to the Indemnifiable Claim; (2) if a quorum cannot be obtained under subdivision (1), by a majority vote of a committee designated by the Board of Directors of the Company (in which designation
directors who are parties may participate), consisting solely of two or more directors not at the time parties to the Indemnifiable Claim; or (3) by Independent Counsel selected by the Board of Directors of the Company or its committee in the
manner prescribed by subdivision (1) or (2), or if a quorum cannot be obtained under subdivision (1) or a committee cannot be designated under subdivision (2), by a majority vote of the full Board of Directors (in which selection directors
who are parties may participate). If a Change in Control shall have occurred and Indemnitee shall not have requested that the Standard of Conduct Determination be made pursuant to the prior sentence, the Standard of Conduct Determination shall be
made by Independent Counsel selected by Indemnitee. Any Standard of Conduct Determination made by Independent Counsel shall be delivered in a written opinion addressed to the applicable Board of Directors, a copy of which shall be provided to
Indemnitee. 
 (c) The Company shall use its reasonable best efforts to cause any Standard of Conduct Determination required under
Section 5(b) to be made as promptly as practicable. If (i) the person or persons empowered or selected under this Section 5 to make the Standard of Conduct Determination shall not have made a determination within sixty (60) days
after the later of (A) receipt by the Company of written notice from Indemnitee advising the Company of the final disposition or other conclusion without final adjudication on the issue of liability of the applicable Indemnifiable Claim and
(B) the selection of an Independent Counsel, if such determination is to be made by Independent Counsel, that is permitted under the provisions of Section 5(d) to make such determination and (ii) Indemnitee shall have fulfilled his or
her obligations set forth in Section 5(e), then Indemnitee shall be deemed to have satisfied the applicable standard of conduct; provided, that such sixty-day period may be extended for a reasonable time, not to exceed an additional
thirty (30) days, if the person or persons making such determination in good faith require such additional time to obtain or evaluate documentation or other information relating thereto. 

(d) If a Standard of Conduct Determination is to be made by Independent Counsel pursuant to Section 5(b), the party who selected such
Independent Counsel shall give notice to the other party advising such party of the identity of the Independent Counsel selected. In either case, the Company or Indemnitee, as applicable, may, within five business days after receiving written notice
of selection from the other, deliver to the other a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not satisfy the criteria
set forth in the definition of “Independent Counsel” in Section 1, and the objection shall set forth with 

  
 5 

 
particularity the factual basis of such assertion. Absent a proper and timely objection, the person or firm so selected shall act as Independent Counsel. If such written objection is timely made
and substantiated, (i) the Independent Counsel so selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is without merit and (ii) the non-objecting party
may, at its option, select an alternative Independent Counsel and give written notice to the other party advising such party of the selection, in which case the provisions of the two immediately preceding sentences and clause (i) of this
sentence shall apply to such subsequent selection and notice. If applicable, the provisions of clause (ii) of the immediately preceding sentence shall apply to successive alternative selections. If no Independent Counsel shall have been
selected within 30 days after the party who makes the selection sends the initial notice of selection, the party who did not make the selection may petition the courts of the State of North Carolina for resolution of any objection which shall have
been made by such party to the other party’s selection and/or for the appointment as Independent Counsel of a person or firm selected by the Court or by such other person as the Court shall designate. In all events, the Company shall pay all of
the reasonable fees and expenses of the Independent Counsel incurred in connection with making a Standard of Conduct Determination pursuant to this Agreement. 

(e) Indemnitee shall cooperate with the person or persons making a Standard of Conduct Determination pursuant to Section 5(b), including
providing to such person or persons, upon reasonable advance request, any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and which the person or persons
making such determination reasonably request. Provided that the person or persons making such Standard of Conduct Determination determine that Indemnitee is entitled to indemnification hereunder, the Company shall further indemnify Indemnitee
against any and all Expenses actually and reasonably incurred by Indemnitee in so cooperating with the person or persons making such Standard of Conduct Determination. 

(f) The Company and Indemnitee acknowledge that, in certain instances, applicable law or public policy may prohibit, or otherwise limit, the
Company’s obligation to indemnify their directors under this Agreement or otherwise. 
 (g) In the event that (i) a determination
is made pursuant to Section 5(b) that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 3, (iii) payment of indemnification is not made
pursuant to Section 5(a) within thirty (30) days after receipt by the Company of a written request therefor, or (iv) payment of indemnification pursuant to Section 5(b) is not made within thirty (30) days after a Standard of
Conduct Determination in which there is not a determination that indemnification is not proper under the circumstances, Indemnitee shall be entitled to seek a judicial determination as to his or her entitlement to such indemnification or advancement
of Expenses. 
 6. Contribution. To the fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is
unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute the amount of Indemnifiable Losses incurred by Indemnitee or on his or her behalf, in such proportion as is deemed fair and
reasonable in light of all the circumstances of the Indemnifiable Claim, in order to reflect (a) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving rise to such Indemnifiable
Claim and/or (b) the relative fault of the Company (and its directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s). The determination of the proportion to be contributed by the Company
to Indemnitee shall be made in the same manner as a Standard of Conduct Determination pursuant to Section 5 hereof. 

  
 6 

 7. Non-Exclusivity. The rights of Indemnitee hereunder shall be in addition to any other rights Indemnitee
may have under the laws of the State of North Carolina, the Articles, the Bylaws, any other agreement, a vote of shareholders or disinterested directors or otherwise. 

8. Successful Defense. To the extent that Indemnitee has been successful on the merits or otherwise in defense of an Indemnifiable Claim or in defense
of any claim, issue or matter therein, he or she shall be indemnified by the Company against any and all Expenses in connection therewith. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a
Claim by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 
 9. Presumptions and
Burdens of Proof. Indemnitee shall be entitled, in any Standard of Conduct Determination or judicial proceeding, to a presumption that he or she is entitled to indemnification, advancement of Expenses or both under this Agreement if he or she
has provided a written request for indemnification pursuant to Section 4. The Company shall bear the burden of proving, by a preponderance of the evidence, that Indemnitee is not entitled to indemnification or advancement. For purposes of this
Agreement, including when making the Standard of Conduct Determination, the termination of any Indemnifiable Claim by judgment, order, settlement, conviction or upon a plea of no contest or its equivalent, shall not, of itself, create a presumption
that Indemnitee did not (a) conduct himself or herself in good faith, (b) reasonably believe (i) in the case of conduct in his or her official capacity with the Company, that his or her conduct was in the Company’s best interests
and (ii) in all other cases, that his or her conduct was at least not opposed to its best interests, and (c) in the case of any Indemnifiable Claim that is a criminal Claim, had no reasonable cause to believe that his or her conduct was
unlawful. 
 10. Insurance. 
 (a) The
Company shall obtain and maintain D&O Insurance with reputable insurance companies on terms with respect to coverage and amount (including with respect to the payment of Expenses) no less favorable than those of the D&O Insurance for the
directors of the Company in effect on the date hereof, except for any changes approved by the Board prior to a Change in Control, provided that such coverage is available on commercially reasonable terms. Indemnitee shall be covered by such D&O
Insurance, in accordance with its terms, to the maximum extent of the coverage available for any director of the Company unless the Company determines in good faith that such insurance is not available, or the premium costs (or increases in premium
costs of other directors or officers of the Company as a result of such coverage) for such insurance is materially disproportionate to the amount of coverage provided. 

(b) Subject to the limitations set forth in Section 12(a) and except as provided in any D&O Insurance maintained by the
Company, the obligation of a the Company to indemnify Indemnitee under this Agreement shall be secondary to any applicable D&O Insurance, and all such D&O Insurance shall be primary to the Company’s obligations hereunder, subject to any
applicable deductible. Except as provided in any D&O Insurance maintained by the Company, in no event shall this Agreement provide (by operation or law or otherwise) any insurance company any right to subrogation to Indemnitee’s rights
hereunder. Except as provided in any D&O Insurance maintained by the Company, in no event shall any insurance company acquire (by subrogation, assignment or otherwise) any right to pursue Indemnitee’s rights hereunder. 

(c) Upon request by Indemnitee, the Company shall provide Indemnitee copies of any applicable D&O Insurance maintained by the Company. The
Company shall promptly notify Indemnitee of any material change in such D&O Insurance coverage. 

  
 7 

 11. Additional Capacities. To the extent that Indemnitee, at the request of the Company, is or was serving
or has agreed to serve in a Constituent Capacity, the indemnification provided hereunder will be secondary to any liability insurance and/or indemnification obligations provided by each Constituent Enterprise, as applicable, and those obligations
will be primary to the Company’s obligations hereunder; provided, however, that so long as Indemnitee has taken reasonable steps to exercise his or her rights and remedies against such Constituent Enterprise prior to seeking
indemnification or advance hereunder, Indemnitee will not be required to exhaust all rights and remedies against such entity prior to enforcing any provision of this Agreement. 

12. Duplication of Payments; Subrogation. 

(a) The Company shall not be liable under this Agreement to make any payment in connection with any Indemnifiable Claim to the extent that
Indemnitee has otherwise received payment of the amounts otherwise payable as indemnity hereunder (including, without limitation, pursuant to any D&O Insurance maintained by the Company. 

(b) In the event of payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the related rights
of recovery of Indemnitee against any other persons or entities. Indemnitee, as a condition of receiving indemnification from the Company, shall execute all documents and do all things that the Company may deem necessary or desirable to perfect such
right of recovery, including the execution of such documents necessary to enable the Company effectively to enforce any such recovery. 
 13. Cooperation
in Defense and Settlement. Indemnitee shall not make any admission or effect any settlement with respect to any Indemnifiable Claim without the Company’s written consent unless Indemnitee shall have determined to undertake his or her own
defense in such matter and has waived any rights to indemnification by or advancement from the Company (arising under this Agreement or otherwise, except to the extent that indemnification may be required by law). The Company shall have the
authority to settle any Indemnifiable Claim to which Indemnitee is a party so long as the Company either (i) obtains Indemnitee’s written consent to such settlement or (ii) such settlement solely involves the payment of money, would
not impose (directly or indirectly) any Expense on Indemnitee and includes a complete and unconditional release of Indemnitee from all liability on any claims that are the subject matter of such Indemnifiable Claim. Neither Indemnitee nor the
Company shall unreasonably withhold consent to a proposed settlement. Indemnitee acknowledges and agrees that if it is ultimately determined that Indemnitee unreasonably withheld consent to the proposed settlement of an Indemnifiable Claim, his or
her unreasonable failure to so consent shall constitute a waiver of all of his or her rights to indemnification and advancement hereunder with respect to such Indemnifiable Claim. Indemnitee and the Company shall cooperate to the extent reasonably
possible with each other and with the Company’s insurers in attempts to defend and/or settle Indemnifiable Claims. 
 14. Assumption of Defense.

 (a) Except as otherwise provided in Section 14(b) below, the Company, jointly with any other indemnifying party similarly
notified, may assume Indemnitee’s defense in any Indemnifiable Claim, with counsel reasonably satisfactory to Indemnitee and the Company. After notice from the Company to Indemnitee of the Company’s election to assume such defense, the
Company will not be liable to Indemnitee under this Agreement or otherwise for Expenses subsequently incurred by Indemnitee in connection with the defense thereof, other than reasonable costs of investigation or as otherwise provided below.
Indemnitee shall have the right to employ counsel in such Indemnifiable Claim, but the fees and expenses of such counsel incurred after notice from the Company of its assumption of the defense thereof shall be at Indemnitee’s own expense
unless: 
  

	 	(i)	The employment of counsel by Indemnitee has been authorized by the Company; or 

  
 8 

	 	(ii)	Indemnitee shall have reasonably concluded that (A) counsel employed by the Company initially is unacceptable or later becomes unacceptable to Indemnitee and the Company has failed to employ reasonably acceptable
counsel in a reasonably timely manner; (B) there may be a conflict of interest between Indemnitee and the Company (or another party being represented jointly with the Company) in the conduct of the defense of such Indemnifiable Claim; or
(C) the Company shall not have employed counsel to assume the defense of such Indemnifiable Claim within a reasonable time following receipt of a written request. 

(b) The Company shall not be entitled to assume the defense of Indemnitee with respect to any Indemnifiable Claim as to which Indemnitee shall
have made either of the conclusions provided for in Section 14(a)(ii)(A) or Section 14(a)(ii)(B). 
 (c) In the
event that Indemnitee notifies the Company that he or she has made any of the conclusions set forth in Section 14(a)(ii), the Company shall be required to indemnify Indemnitee against and advance or reimburse to Indemnitee all Expenses
incurred (whether incurred by Indemnitee before or after the delivery of such notice) with respect to such Indemnifiable Claim while any of the conditions set forth in Section 14(a)(ii) are present to the fullest extent provided
hereunder (including Expenses incurred by Indemnitee with respect to the preparation and delivery of such notice). 
 (d) If the Company
disagrees with Indemnitee’s conclusion under Section 14(a)(ii), the Company shall, within 30 days after the receipt of notice from Indemnitee, appoint Independent Counsel consistent with the procedures specified
in Section 5(b) to resolve the dispute. If the Independent Counsel determines that Indemnitee’s conclusion under Section 14(a)(ii) was reasonable, the Company shall further indemnify Indemnitee against any and all
Expenses actually and reasonably incurred by Indemnitee in so cooperating with such Independent Counsel. 
 (e) For the avoidance of doubt,
regardless of whether the Company has assumed or is entitled to assume Indemnitee’s defense, the Company shall be entitled to participate in any Indemnifiable Claim at its own expense. 

15. Successors and Binding Agreement. 

(a) The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation, reorganization or otherwise) to
all or substantially all of the business or assets of the Company, by agreement in form and substance reasonably satisfactory to Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent the
Company would be required to perform if no such succession had taken place. This Agreement shall be binding upon and inure to the benefit of the Company and any successor to the Company, including without limitation any person acquiring directly or
indirectly all or substantially all of the business or assets of the Company, whether by purchase, merger, consolidation, reorganization or otherwise (and such successor will thereafter be deemed the “Company” for purposes of this
Agreement). 
 (b) The indemnification and advancement of Expenses provided by this Agreement shall continue as to a person who has ceased
to be a director or officer or who is deceased and shall inure to the benefit of and be enforceable by the personal or legal representatives, executors, administrators, heirs, distributees, legatees and other successors of such person. 

(c) This Agreement is personal in nature and neither of the parties hereto may, without the written consent of the other, assign or delegate
this Agreement or any rights or obligations hereunder 

  
 9 

 
except as provided in Section 15(a) and Section15(b). Without limiting the generality or effect of the foregoing, Indemnitee’s right to receive payments hereunder shall not be
assignable, whether by pledge, creation of a security interest or otherwise, other than by a transfer by Indemnitee’s will or by the laws of descent and distribution, and, in the event of any attempted assignment or transfer contrary thereto,
the Company shall have no liability to pay any amount so attempted to be assigned or transferred. 
 16. Miscellaneous. 

(a) Notice of Claim; Notices. Indemnitee agrees promptly to notify the Company in writing upon being served with any summons,
citation, subpoena, complaint, indictment, information or other document relating to any Claim or matter which may be subject to indemnification or advancement hereunder. Any failure to so notify the Company shall not relieve the Company of any
obligation which it may have to Indemnitee under this Agreement or otherwise unless and only to the extent that such failure or delay materially prejudices the Company. All notices, requests and other communications hereunder must be in writing and
will be deemed to have been duly given only if delivered personally against written receipt or by facsimile transmission or mailed by prepaid first class mail, return receipt requested, or sent by overnight courier prepaid to the parties at the
following addresses or facsimile numbers:

(b) Governing Law. The validity, interpretation, construction and performance of this Agreement shall be governed by, and construed and
enforced in accordance with, the substantive laws of the State of North Carolina, without giving effect to its principles of conflict of laws. The Company and Indemnitee each hereby irrevocably consent that both parties are subject to the
jurisdiction of the state courts of the State of North Carolina for all purposes in connection with any action or proceeding that arises out of or relates to this Agreement, and further agree that the sole and exclusive venue for any such dispute
shall be the General Court of Justice, Superior Court Division, in Mecklenburg County, North Carolina. The parties stipulate and agree that any such dispute shall be designated by agreement of the parties as a “mandatory complex business
case” pursuant to N.C.G.S. § 7A-45.4 (as such statute may be amended from time to time) or, in the alternative, as a discretionary “complex business” case under Rule 2.1 of the North Carolina General Rules of Practice for
the Superior and District Courts (as such rule 

  
 10 

 
may be amended from time to time), and both parties hereby irrevocably waive any objection to such dispute being so designated. In the event the parties are unable to secure designation of the
dispute as a complex business case, or if such designation is revoked at any time, the parties agree that they shall request that the dispute be designated as an “exceptional” case pursuant to Rule 2.1 of the North Carolina General Rules
of Practice for the Superior and District Courts (as such rule may be amended from time to time) and agree to cooperate in good faith to secure such designation. 

(c) Validity. If any provision of this Agreement or the application of any provision hereof to any person or circumstance is held
invalid, unenforceable or otherwise illegal, the remainder of this Agreement and the application of such provision to any other person or circumstance shall not be affected, and the provision so held to be invalid, unenforceable or otherwise illegal
shall be reformed to the extent, and only to the extent, necessary to make it enforceable, valid or legal. In the event that any court or other adjudicative body shall decline to reform any provision of this Agreement held to be invalid,
unenforceable or otherwise illegal as contemplated by the immediately preceding sentence, the parties hereto shall take all such action as may be necessary or appropriate to replace the provision so held to be invalid, unenforceable or otherwise
illegal with one or more alternative provisions that effectuate the purpose and intent of the original provisions of this Agreement as fully as possible without being invalid, unenforceable or otherwise illegal. 

(d) Amendment; Waiver. This Agreement may not be modified or amended except by a written instrument executed by or on behalf of each of
Indemnitee and the Company. The observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) only by a writing signed by the party against which such waiver is to be
asserted, and no waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not similar) nor shall such waiver constitute a continuing waiver. 

(e) Entire Agreement. This Agreement constitutes the entire agreement between the Company and Indemnitee with respect to the subject
matter hereof and supersedes any prior agreements between them with respect to the subject matter hereof, including without limitation the Prior Agreement. 

(f) Headings. The headings used in this Agreement have been inserted for convenience of reference only and do not define or limit the
provisions hereof. 
 (g) Certain Interpretive Matters. Unless the context of this Agreement otherwise requires,
(i) “it” or “its” or words of any gender include each other gender; (ii) words using the singular or plural number also include the plural or singular number, respectively; (iii) the terms “hereof,”
“herein,” “hereby” and derivative or similar words refer to this entire Agreement; (iv) the term “Section” refers to the specified Section of this Agreement; (v) the terms “include,”
“includes” and “including” shall be deemed to be followed by the words “without limitation” (whether or not so expressed); and (vi) the word “or” is disjunctive but not exclusive. No provision of this
Agreement will be interpreted in favor of, or against, either of the parties hereto by reason of the extent to which any such party or its counsel participated in the drafting thereof or by reason of the extent to which any such provision is
inconsistent with any prior draft hereof or thereof. 
 (h) Counterparts. This Agreement may be executed in one or more counterparts,
and delivered by facsimile or other means of electronic transmission, each of which shall be deemed to be an original but all of which together shall constitute one and the same agreement.
