Ladies and Gentlemen:

CenterState Banks, Inc., a Florida corporation (the “Company”), confirms its agreement with Keefe, Bruyette & Woods, Inc. (“Keefe Bruyette”) and each of the other Underwriters named in Schedule A hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for whom Keefe Bruyette is acting as representative (in such capacity, the “Representative”), with respect to (i) the sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of the respective numbers of 3,600,000 shares of Common Stock, $0.01 par value per share, of the Company (“Common Stock”) set forth in Schedule A hereto and (ii) the grant by the Company to the Underwriters, acting severally and not jointly, of the option described in Section 2(b) hereof to purchase all or any part of 540,000 additional shares of Common Stock to cover over-allotments, if any. The aforesaid 3,600,000 shares of Common Stock (the “Initial Securities”) to be purchased by the Underwriters and all or any part of the 540,000 shares of Common Stock subject to the option described in Section 2(b) hereof (the “Option Securities”) are hereinafter called, collectively, the “Securities.”

The Company understands that the Underwriters propose to make a public offering of the Securities as soon as the Representative deems advisable after this Agreement has been executed and delivered. The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (No. 333-163465), including the related base prospectus, covering the registration of certain classes of securities of the Company (including the Securities) under the Securities Act of 1933, as amended (the “1933 Act”), for offer and sale from time to time in accordance with Rule 415 of the rules and regulations of the Commission promulgated under the 1933 Act (the “1933 Act Regulations”). Such registration statement has been declared effective by the Commission under the 1933 Act. Promptly after

execution and delivery of this Agreement, the Company will prepare and file a prospectus supplement in accordance with the provisions of Rule 430B of the 1933 Act Regulations (“Rule 430B”) and paragraph (b) of Rule 424 of the 1933 Act Regulations (“Rule 424(b)”). Any information included in such prospectus supplement that was omitted from such registration statement at the time it became effective but that is deemed to be part of and included in such registration statement pursuant to Rule 430B is referred to herein as “Rule 430B Information.” Each base prospectus and prospectus supplement used in connection with the offering of the Securities that omitted Rule 430B Information is referred to herein collectively as a “preliminary prospectus.” Such registration statement, including the amendments thereto, the exhibits and any schedules thereto, the documents incorporated or deemed incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, at the time it became effective and including the Rule 430B Information, is referred to herein as the “Registration Statement;” provided, however, that the term “Registration Statement” without reference to a time means such registration statement as of the time of the first contract of sale for the Securities, which time shall be considered the “new effective date” of such registration statement with respect to the Underwriters and the Securities (within the meaning of Rule 430B(f)(2)); provided, further, that any registration statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is referred to herein as the “Rule 462(b) Registration Statement,” and after such filing the term “Registration Statement” shall include the Rule 462(b) Registration Statement. The final base prospectus and the prospectus supplement, in the form first furnished or made available to the Underwriters for use in connection with the confirmations of sales of the Securities, including the documents incorporated or deemed incorporated by reference therein, are referred to herein collectively as the “Prospectus.” For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system or any successor system thereto (collectively, “EDGAR”).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Registration Statement, any preliminary prospectus, the Prospectus or the General Disclosure Package (as defined herein) (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is or is deemed to be incorporated by reference in or otherwise deemed by the 1933 Act Regulations to be a part of or included in the Registration Statement, any preliminary prospectus, the Prospectus or the General Disclosure Package, as the case may be, prior to the execution of this Agreement; and all references in this Agreement to amendments or supplements to the Registration Statement, any preliminary prospectus, the Prospectus or the General Disclosure Package shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the “1934 Act”), which is or is deemed to be incorporated by reference in or otherwise deemed by the 1933 Act Regulations to be a part of or included in the Registration Statement, such preliminary prospectus, the Prospectus or the General Disclosure Package, as the case may be, at or after the execution of this Agreement.

The Company meets the requirements for use of Form S-3 under the 1933 Act. The Registration Statement (including any Rule 462(b) Registration Statement) has been declared effective by the Commission under the 1933 Act and no stop order suspending the effectiveness of the Registration Statement and any post-effective amendment thereto or any Rule 462(b) Registration Statement has been issued under the 1933 Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated by the Commission. No order preventing or suspending the use of any preliminary prospectus, the Statutory Prospectus (as defined below) or the Prospectus has been issued and no proceeding for that purpose has been instituted or is pending or, to the knowledge of the Company, is threatened or contemplated by the Commission. The Company has fully complied with any request on the part of the Commission.

At the respective times the Registration Statement (including any Rule 462(b) Registration Statement) and any post-effective amendments thereto became effective, at each deemed effective date with respect to the Underwriters and the Securities pursuant to Rule 430B(f)(2), at the Closing Time and at each Date of Delivery (if any), each of the Registration Statement and any amendment or supplement thereto complied and will comply in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations, and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. Neither the Prospectus nor any amendment or supplement thereto, at the respective dates of the Prospectus or such amendment or supplement, at the respective times that the Prospectus and any such amendment or supplement were issued, at the Closing Time or at any Date of Delivery, included or will include an untrue statement of a material fact or omitted, omits or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

At the Applicable Time, each Issuer-Represented Free Writing Prospectus (as defined below) identified on Schedule B hereto, the Statutory Prospectus and the information agreed to in writing by the Company and the Underwriters as the information to be conveyed orally by the Underwriters to purchasers of the Securities at the Applicable Time as set forth on Schedule C hereto, all considered together (collectively, the “General Disclosure Package”), did not include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

The representations and warranties in the preceding two paragraphs shall not apply to statements in or omissions from the Registration Statement or any amendment thereto or any preliminary prospectus, the Prospectus, the Issuer-Represented Free Writing Prospectus or the General Disclosure Package or any amendment or supplement thereto made in reliance upon and in conformity with information furnished to the Company in writing by the Representative on behalf of the Underwriters expressly for use therein.

Any preliminary prospectus, the Statutory Prospectus and the Prospectus complied or will comply, as the case may be, when filed with the Commission in all material respects with the 1933 Act and the 1933 Act Regulations.

As used in this subsection and elsewhere in this Agreement:

“Applicable Time” means 8:00 A.M./P.M. (New York City time) on the date of this Agreement or such other time as agreed by the Company and Keefe Bruyette.

“Statutory Prospectus,” at any given time, means the base prospectus that is included in the Registration Statement and the preliminary prospectus supplement relating to the Securities immediately prior to that time, including the documents incorporated or deemed incorporated by reference therein at such time. For purposes of this definition, information contained in a form of prospectus that is deemed retroactively to be a part of the Registration Statement pursuant to Rule 430B shall be considered to be included in the Statutory Prospectus only at the actual time that such form of prospectus is filed with the Commission pursuant to Rule 424(b).

“Issuer-Represented Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule 433 of the 1933 Act Regulations (“Rule 433”), relating to the Securities that (i) is required to be filed with the Commission by the Company, (ii) is a “road show that is a written communication” within the meaning of Rule 433(d)(8)(i), whether or not required to be filed with the Commission, or (iii) is exempt from filing with the Commission pursuant to Rule 433(d)(5)(i) because it contains a description of the Securities or of the offering that does not reflect the final terms, in each case in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g).

Each Issuer-Represented Free Writing Prospectus, at its issue date and at all subsequent times through the completion of the public offering contemplated hereby or until any earlier date that the Company notified or notifies Keefe Bruyette as described in Section 3(e) hereof, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, any preliminary prospectus, the Statutory Prospectus or the Prospectus, including any document incorporated or deemed incorporated by reference therein and any preliminary or other prospectus deemed to be a part thereof that has not been superseded or modified.

regulations of the Commission thereunder (the “1934 Act Regulations”), as applicable, and when read together with the other information in the Registration Statement, the General Disclosure Package or the Prospectus, as the case may be, (a) at the original effectiveness of the Registration Statement, (b) at the earlier of the time the Prospectus was first used and the date and time of the first contract of sale of the Securities, (c) at the Closing Time and (d) at each Date of Delivery (if any), did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(xxvii) Statistical and Market Data. The statistical and market related data contained in the Registration Statement, the General Disclosure Package and the Prospectus are based on or derived from sources which the Company believes are reliable and accurate.

(xxviii) Relationship. No relationship, direct or indirect, exists between or among the Company or any of its subsidiaries, on the one hand, and the directors, officers, shareholders, customers or suppliers of the Company or any of its subsidiaries, on the other hand, that is required by the 1933 Act or the 1933 Act Regulations to be described in the Registration Statement and the Prospectus and that is not so described.

(xxix) Internal Control over Financial Reporting. The Company and each of its Subsidiaries maintains a system of internal accounting controls sufficient to provide reasonable assurance that (A) transactions are executed in accordance with management’s general or specific authorizations; (B) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain asset accountability; (C) access to assets is permitted only in accordance with management’s general or specific authorization; and (D) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Except as described in the Registration Statement, General Disclosure Package and Prospectus, since the end of the Company’s most recent audited fiscal year, there has been (1) no material weakness in the Company’s internal control over financial reporting (whether or not remediated) and (2) no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

(xxx) Disclosure Controls and Procedures. The Company and its subsidiaries employ disclosure controls and procedures (as such term is defined in Rule 13a-15 under the 1934 Act Regulations), which (A) are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the 1934 Act is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms and that material information relating to the Company and its subsidiaries is made known to the Company’s principal executive officer and principal financial officer by others within the Company and its subsidiaries to allow timely decisions regarding disclosure, and (B) are effective in all material respects to perform the functions for which they were established. Based on the evaluation of the Company’s and each subsidiary’s disclosure controls and procedures described above, the Company is not aware of (1) any significant deficiency in the design or operation of internal controls which could adversely affect the Company’s ability to record, process, summarize and report financial data or any material weaknesses in internal controls or (2) any fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s internal controls. Since the most recent evaluation of the Company’s disclosure controls and procedures described above, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls.

(xxxi) Compliance with the Sarbanes-Oxley Act.

SECTION 2. Sale and Delivery to Underwriters; Closing.

(a) Initial Securities. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to sell to each Underwriter, severally and not jointly, and each Underwriter, severally and not jointly, agrees to purchase from the Company, the Initial Shares at the price per share set forth in Schedule C, the number of Initial Securities set forth in Schedule A opposite the name of such Underwriter, plus any additional number of Initial Securities which such Underwriter may

become obligated to purchase pursuant to the provisions of Section 10 hereof, bears to the total number of Initial Securities, subject, in each case, to such adjustments among the Underwriters as the Representative in its sole discretion shall make to eliminate any sales or purchases of fractional shares.

(b) Option Securities. In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the Underwriters, severally and not jointly, to purchase up to an additional 540,000 Option Securities, at the price per share set forth in Schedule C hereto, less an amount per share equal to any dividends or distributions declared by the Company and payable on the Initial Securities but not payable on the Option Securities. The option hereby granted will expire 30 days after the date hereof and may be exercised in whole or in part from time to time only for the purpose of covering over-allotments which may be made in connection with the offering and distribution of the Initial Securities upon notice by the Representative to the Company setting forth the number of Option Securities as to which the several Underwriters are then exercising the option and the time and date of payment and delivery for such Option Securities. Any such time and date of delivery (a “Date of Delivery”) shall be determined by the Representative, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time, as hereinafter defined. If the option is exercised as to all or any portion of the Option Securities, each of the Underwriters, acting severally and not jointly, will purchase that proportion of the total number of Option Securities then being purchased which the number of Initial Securities set forth in Schedule A opposite the name of such Underwriter bears to the total number of Initial Securities, subject in each case to such adjustments as the Representative in its discretion shall make to eliminate any sales or purchases of fractional shares.

(c) Payment. Payment of the purchase price for, and delivery of certificates for, the Initial Securities shall be made at the offices of Jones Day, 1420 Peachtree Street, N.E., Suite 800, Atlanta, Georgia 30309, or at such other place as shall be agreed upon by the Representative and the Company, at 9:00 A.M. (Eastern time) on the third (fourth, if the pricing occurs after 4:30 P.M. (Eastern time) on any given day) business day after the date hereof (unless postponed in accordance with the provisions of Section 10 hereof), or such other time not later than ten (10) business days after such date as shall be agreed upon by the Representative and the Company (such time and date of payment and delivery being herein called the “Closing Time”).

In addition, in the event that any or all of the Option Securities are being purchased by the Underwriters, payment of the purchase price for, and delivery of certificates for, such Option Securities shall be made at the above mentioned offices, or at such other place as shall be agreed upon by the Representative and the Company, on each Date of Delivery as specified in the notice from the Representative to the Company.

Payment shall be made to the Company by wire transfer of immediately available funds to a bank account designated by the Company against delivery to the Representative for the respective accounts of the Underwriters of certificates for the Securities being purchased by them. The Company shall deliver the Initial Securities and Option Securities, if any, through the facilities of The Depository Trust Company (the “DTC”) unless the Representative shall otherwise instruct. It is understood that each Underwriter has authorized the Representative, for

its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Initial Securities and the Option Securities, if any, which it has agreed to purchase. Keefe Bruyette individually and not as Representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Initial Securities or the Option Securities, if any, being purchased by any Underwriter whose funds have not been received by the Closing Time or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder.

(d) Denominations; Registration. Certificates for the Initial Securities and the Option Securities, if any, shall be in such denominations and registered in such names as the Representative may request in writing at least one full business day before the Closing Time or the relevant Date of Delivery, as the case may be. The certificates for the Initial Securities and the Option Securities, if any, will be made available for examination and packaging by the Representative in The City of New York not later than 10:00 A.M. (Eastern time) on the business day prior to the Closing Time or the relevant Date of Delivery, as the case may be.

SECTION 6. Indemnification.

(a) Indemnification of Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, its Affiliates, its selling agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, including the Rule 430B Information, or any amendment thereto or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus, the Statutory Prospectus, any Issuer-Represented Free Writing Prospectus, the General Disclosure Package, the Prospectus or the roadshow materials used in connection with the offer of the Securities or in any amendment or supplement thereto or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any Governmental Entity, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by Keefe Bruyette), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any Governmental Entity, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under clause (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through Keefe Bruyette expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430B Information or any preliminary prospectus, any Issuer-Represented Free Writing Prospectus, or the Prospectus (or any amendment or supplement thereto); provided that the parties acknowledge and agree that the only written information that the Underwriters have furnished to the Company specifically for inclusion in the Registration Statement, preliminary prospectus and Prospectus (or any amendment or supplement thereto) are the concession and reallowance figures appearing in the Prospectus in the section entitled “Underwriting” and the information contained under the caption “Underwriting — Price Stabilization, Short Positions and Passive Market Making.”

(b) Indemnification of Company, Directors and Officers. Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 6(a), as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement, including the Rule 430B Information, or any amendment thereto, or in any preliminary prospectus, the Statutory Prospectus, any Issuer-Represented Free Writing Prospectus, the General Disclosure Package or the Prospectus or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by such Underwriter through Keefe Bruyette expressly for use therein; it being understood that the parties acknowledge and agree that the only written information that the Underwriters have furnished to the Company specifically for inclusion therein is the concession and reallowance figures appearing in the Prospectus in the section entitled “Underwriting” and the information contained under the caption “Underwriting — Price Stabilization, Short Positions and Passive Market Making.”

(c) Actions Against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by Keefe Bruyette and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the written consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any Governmental Entity, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement Without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions, which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, on the one hand, and the total underwriting discount received by the Underwriters, on the other hand, in each case as set forth on the cover of the Prospectus.

The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company, on the one hand, and the Underwriters, on the other hand, agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any Governmental Entity, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue statement or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Underwriter’s Affiliates and selling agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial Securities set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers and other representatives of the Company or any of its subsidiaries submitted pursuant hereto shall remain operative and in full force and effect, regardless of any (i) investigation made by or on behalf of any Underwriter or its Affiliates or selling agents, any person controlling any Underwriter or its officers or other representatives, or by or on behalf of the Company, and (ii) delivery of and payment for the Securities.

SECTION 9. Termination of Agreement.

(a) Termination; General. The Representative may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time (i) if there has been, since the respective dates as of which information is given in the Registration Statement, the General Disclosure Package or the Prospectus, any Material Adverse Effect, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, including, without limitation, as a result of terrorist activities, in each case the effect of which is such as to make it, in the judgment of the Representative, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or The Nasdaq Global Select Market, or if trading generally or the New York Stock Exchange or in The Nasdaq Global Select Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, FINRA or any other Governmental Entity, or (iv) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or Europe, or (v) if a banking moratorium has been declared by either United States federal, Florida or New York authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7, 8, 12, 13, 14, 15 and 16 shall survive such termination and remain in full force and effect.

SECTION 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representative shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representative shall not have completed such arrangements within such 24 hour period, then:

(a) if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(b) if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Underwriters to purchase and of the Company to sell the Option Securities to be purchased and sold on such Date of Delivery shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Company to sell the relevant Option Securities, as the case may be, either the Representative or the Company shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

SECTION 11. Default by the Company. If the Company shall fail at the Closing Time or at the Date of Delivery to sell the number of Securities that it is obligated to sell hereunder, then this Agreement shall terminate without any liability on the part of any nondefaulting party; provided, however, that the provisions of Sections 1, 4, 6, 7, 8, 11, 12, 13, 14, 15 and 16 shall remain in full force and effect. No action taken pursuant to this Section shall relieve the Company from liability, if any, in respect of such default.

SECTION 12. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to the Representative at Keefe, Bruyette & Woods, Inc., 787 Seventh Avenue, 4th Floor, New York, New York 10019, attention of the General Counsel; notices to the Company shall be directed to it at CenterState Banks, Inc., 42745 U.S. Highway 27, Davenport, Florida 33837, attention of Ernest S. Pinner.

SECTION 13. Parties. This Agreement shall each inure to the benefit of and be binding upon the Underwriters and the Company and their respective successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Company and their respective successors and assigns and the controlling persons and officers, directors, Affiliates and selling agents referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters and the Company and their respective successors and assigns, and said controlling persons, officers, directors, Affiliates and selling agents and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

SECTION 14. No Fiduciaries. The Company acknowledges and agrees that (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s length commercial transaction between the Company, on the one hand, and the Underwriters, on the other hand, (ii) in connection with the offering contemplated hereby and the process leading to such transaction, each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company, any of the Company’s subsidiaries, any shareholders, creditors or employees of the Company or any of its subsidiaries or any other third party, (iii) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company or any of its subsidiaries with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company or any of its subsidiaries on other matters), and no Underwriter has any obligation to the Company or any of its subsidiaries with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, (iv) the Underwriters and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and its subsidiaries, and (v) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

SECTION 15. GOVERNING LAW AND TIME. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

SECTION 16. General Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, but all of which together shall constitute one and the same instrument. The exchange of copies of this Agreement and of signature pages by facsimile or other electronic means shall constitute effective execution and delivery of this Agreement by the parties hereto and may be used in lieu of the original signature pages to this Agreement for all purposes. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The Section and provision headings herein are for convenience only and shall not affect the construction hereof.

The activities of the Company as described in the Prospectus are permitted of a bank holding company under the BHCA. The Company has all necessary approvals of the Board of Governors of the Federal Reserve System to own the capital stock of its subsidiaries.

(ii) The Company has all necessary corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Prospectus and to enter into and perform its obligations under the Underwriting Agreement.

(iii) The Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not result in a Material Adverse Effect.

(iv) The authorized, issued and outstanding capital stock of the Company is as set forth in the Prospectus in the column entitled “Actual” under the caption “Capitalization” (except for subsequent issuances, if any, pursuant to the Underwriting Agreement or pursuant to reservations, agreements or employee benefit plans referred to in the Prospectus or pursuant to the exercise of convertible securities or options referred to in the Prospectus); the shares of issued and outstanding capital stock of the Company have been duly authorized and validly issued and are fully paid and non-assessable; and none of the outstanding shares of capital stock of the Company was issued in violation of the preemptive or other similar rights of any securityholder of the Company.

(v) The Securities to be purchased by the Underwriters from the Company have been duly authorized for issuance and sale to the Underwriters pursuant to the Underwriting Agreement and, when issued and delivered by the Company pursuant to the Underwriting Agreement against payment of the consideration set forth in the Underwriting Agreement, will be validly issued and fully paid and non-assessable and no holder of the Securities is or will be subject to personal liability by reason of being such a holder.

(vi) The issuance and sale of the Securities by the Company is not subject to the preemptive or other similar rights of any securityholder of the Company.

(vii) Each of CenterState Bank Central Florida National Association (“Central”), CenterState Bank National Association (“CSNA”) and CenterState Bank of Florida National Association (“CSB” and, together with Central and CSNA, the “National Banks”) has been duly organized and is validly existing as a national bank and is in good standing under the laws of the United States of America. Each National Bank has the corporate power to own, lease and operate its current properties and to conduct its business as described in the Prospectus. The activities of the National Banks as described in the Prospectus are permitted of national banks under the National Bank Act. All of the issued and outstanding capital stock of each National Bank has been duly authorized, is validly issued, fully paid and non-assessable and is owned by the Company free and clear of any security interest, mortgage, pledge, lien, encumbrance, claim or equity. None of the outstanding shares of capital stock of any of the National Banks was issued in violation of the preemptive or similar rights of any securityholder of any National Bank.

(viii) Valrico State Bank (“VSB” and, together with the National Banks, the “Banks”) has been duly organized and is validly existing as a state-chartered bank and is in good standing under the laws of the State of Florida. VSB has the corporate power to own, lease and operate its current properties and to conduct its business as described in the Prospectus. The activities of VSB as described in the Prospectus are permitted of a state-chartered bank under the laws and regulations of the State of Florida and the Florida Office of Financial Regulation. All of the issued and outstanding capital stock of VSB has been duly authorized, is validly issued, fully paid and non-assessable and is owned by the Company free and clear of any security interest, mortgage, pledge, lien, encumbrance, claim or equity. None of the outstanding shares of capital stock of VSB was issued in violation of the preemptive or similar rights of any securityholder of VSB.

(xviii) The information (i) in the Prospectus under “Description of Preferred Stock”, “Description of Common Stock”, “Underwriting” and “Anti-Takeover Effects of Certain Provisions”; (ii) in the Company’s Annual Report on Form 10-K and Form 10-K/A for the year ended December 31, 2009 under the headings “Business — Interest and Usury”, “Business — Supervision and Regulation”, “Properties” and “Legal Proceedings”; and (iii) in the Registration Statement under Item 15, in each case to the extent that it constitutes matters of law, summaries of legal matters, the Company’s charter and bylaws or legal proceedings, or legal conclusions, has been reviewed by us and is correct in all material respects.

(xxi) Neither the Company nor any subsidiary is in violation of its charter or by-laws and to our knowledge, no default by the Company or any subsidiary exists in the due performance or observance of any material obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, loan agreement, note, lease or other agreement or instrument that is described or referred to in the Registration Statement or the Prospectus or filed or incorporated by reference as an exhibit to the Registration Statement.

(xxii) No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency, domestic or foreign (other than under the 1933 Act and the 1933 Act Regulations, which have been obtained, or as may be required under the securities or blue sky laws of the various states, as to which we express no opinion) is necessary or required in connection with the due authorization, execution and delivery of the Underwriting Agreement or for the offering, issuance, sale or delivery of the Securities.

(xxiii) The execution, delivery and performance of the Underwriting Agreement and the consummation of the transactions contemplated in the Underwriting Agreement and in the Registration Statement (including the issuance and sale of the Securities and the use of the proceeds from the sale of the Securities as described in the Prospectus under the caption “Use of Proceeds”) and compliance by the Company with its obligations under the Underwriting Agreement do not and will not, whether with or without the giving of notice or lapse of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined in Section 1(a)(xi) of the Underwriting Agreement) under or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any subsidiary

pursuant to any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or any other agreement or instrument, known to us, to which the Company or any subsidiary is a party or by which it or any of them may be bound, or to which any of the property or assets of the Company or any subsidiary is subject (except for such conflicts, breaches or defaults or liens, charges or encumbrances that would not have a Material Adverse Effect), nor will such action result in any violation of the provisions of the charter or by-laws of the Company or any subsidiary, or any applicable law, statute, rule, regulation, judgment, order, writ or decree, known to us, of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any subsidiary or any of their respective properties, assets or operations.

(xxiv) The Company is not an “investment company” or an entity “controlled” by an “investment company,” as such terms are defined in the 1940 Act.

Nothing has come to our attention that would lead us to believe that the Registration Statement or any amendment thereto (including the Rule 430B Information but excluding the financial statements, the notes thereto and schedules and other financial data included or incorporated by reference therein or omitted therefrom, as to which we make no statement), at the time such Registration Statement or any such amendment became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or that the Prospectus or any amendment or supplement thereto (except for financial statements, the notes thereto and schedules and other financial data included or incorporated by reference therein or omitted therefrom, as to which we make no statement), at the time the Prospectus was issued, at the time any such amended or supplemented prospectus was issued or at the Closing Time, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Furthermore, we have no reason to believe that the documents specified in the General Disclosure Package, as of the Applicable Time and as of the Closing Time, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

In rendering such opinion, such counsel may rely, as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on certificates of responsible officers of the Company and public officials. Such opinion shall not state that it is to be governed or qualified by, or that it is otherwise subject to, any treatise, written policy or other document relating to legal opinions, including, without limitation, the Legal Opinion Accord of the ABA Section of Business Law (1991).

Dear Sirs:

The undersigned, a shareholder [and an executive officer and/or director] of CenterState Banks, Inc., a Florida corporation (the “Company”), understands that Keefe, Bruyette & Woods, Inc. (“Keefe Bruyette”), as representative of the Underwriters, proposes to enter into an Underwriting Agreement (the “Underwriting Agreement”) with the Company providing for the public offering of shares (the “Securities”) of the Company’s common stock, $0.01 par value per share (the “Common Stock”). In recognition of the benefit that such an offering will confer upon the undersigned as a shareholder [and an executive officer and/or director] of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each underwriter to be named in the Underwriting Agreement that, during a period of 90 days from the date of the Underwriting Agreement, the undersigned will not, without the prior written consent of Keefe Bruyette, directly or indirectly, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any shares of the Company’s Common Stock or any securities convertible into or exchangeable or exercisable for Common Stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition, or file any registration statement under the Securities Act of 1933, as amended, with respect to any of the foregoing or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Common Stock, whether any such swap or transaction is to be settled by delivery of Common Stock or other securities, in cash or otherwise. In the event that either (i) during the period that begins on the date that is 15 calendar days plus three (3) business days before the last day of the 90-day restricted period and ends on the last day of the 90-day restricted period, the Company issues an earnings release or material news or a material event relating to the Company occurs, or (ii) prior to the expiration of the 90-day restricted period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 90-day restricted period, the restrictions set forth herein will continue to apply until the expiration of the date that is 15 calendar days plus three (3) business days after the date on which the earnings release is issued or the material news or event related to the Company occurs. The Company shall promptly notify Keefe Bruyette of any earnings releases, news or events that may give rise to an extension of the initial restricted period.

Notwithstanding the foregoing, the undersigned may transfer the undersigned’s shares of Common Stock (i) as a bona fide gift or gifts, provided that the donee or donees agree to be bound in writing by the restrictions set forth herein, (ii) to any trust or family limited partnership for the direct or

indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust or general partner of the family limited partnership, as the case may be, agrees to be bound by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, (iii) pledged in a bona fide transaction outstanding as of the date hereof to a lender to the undersigned, as disclosed in writing to the underwriter (iv) pursuant to the exercise by the undersigned of stock options that have been granted by the Company prior to, and are outstanding as of, the date of the Underwriting Agreement, where the Common Stock received upon any such exercise is held by the undersigned, individually or as fiduciary, in accordance with the terms of this Lock-Up Agreement, or (v) with the prior written consent of Keefe Bruyette. For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.

The undersigned now has and, except as contemplated by clauses (i) through (v) above, for the duration of the Lock-Up Agreement will have good and marketable title to the undersigned’s shares of Common Stock, free and clear of all liens, encumbrances, and claims whatsoever, except with respect to any liens, encumbrances and claims that were in existence on the date hereof. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s common stock, except in compliance with this Lock-Up Agreement. In furtherance of the foregoing, the Company and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Agreement.

The undersigned represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Agreement. The undersigned agrees that the provisions of this Lock-Up Agreement shall be binding also upon the successors, assigns, heirs and personal representatives of the undersigned.

The undersigned understands that, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock to be sold thereunder, the undersigned shall be released from all obligations under this Lock-up Agreement.

This Lock-up Agreement shall be governed by and construed in accordance with the laws of the State of New York.
