CHANGE OF CONTROL AGREEMENT AGREEMENT by and between Seacoast Banking Corporation of Florida (the “Company”) and Xxxxxx Xxxxxx (“Executive”), dated as of the 20th day of January, 2021. The Board of Directors of the Company (the “Board”), has determined that it is in the best interests of the Company and its stockholders to assure that the Company will have the continued dedication of Executive, notwithstanding the possibility, threat or occurrence of a Change of Control (as defined below) of the Company. The Board believes it is imperative to diminish the inevitable distraction of Executive by virtue of the personal uncertainties and risks created by a pending or threatened Change of Control and to encourage Executive’s full attention and dedication to the Company currently and in the event of any threatened or pending Change of Control, and to provide Executive with compensation and benefits arrangements upon a Change of Control which ensure that the compensation and benefits expectations of Executive will be satisfied and which are competitive with those of other corporations. Therefore, in order to accomplish these objectives, the Board has caused the Company to enter into this Agreement. NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS: 1. Certain Definitions.

The Company shall furnish to Executive in writing a notice of the subsection relied upon and describing the facts establishing Cause under that subsection. In the event that the Company seeks to terminate Executive’s employment for Cause and that subsection (iv), (viii) or (ix) of such definition in Section 1(a) is the sole reason for termination for Cause, Executive shall have the following cure provisions and rights. Following the Company’s delivery of the Cause notice described above, Executive shall have a period of ten (10) days after the giving of such written notice of proposed termination by the Company in which to attempt to effect a cure of the specified Cause. If at the end of such ten (10) day period no such cure has been effected to the satisfaction of the Board as determined in good faith, then Executive’s employment shall be terminated for Cause as of the end of such ten (10) day period. The Company shall be obligated to provide to Executive only one such notice of proposed termination. If subsequent to effecting a cure of specified deficiencies under subsection (iv), (viii) or (ix) of such definition in Section 1(a), Executive is determined by the Board again to have committed an act of Cause under subsection (iv), (viii) or (ix) of such definition in Section 1(a), then employment may be terminated immediately for Cause upon the Company’s giving of notice of termination to Executive.

Change of Control Agreement Page 9 LEGAL02/36557583v4 provision so indicated, and (iii) specifies the termination date (which date shall be not less than 60 days after the giving of such notice). The failure by either party to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Good Reason or Cause shall not waive any right of such party hereunder or preclude such party from asserting such fact or circumstance in enforcing such party’s rights hereunder. 5. Obligations of the Company upon Termination. (a) Termination by the Company Other Than for Cause or Disability; Termination by Executive for Good Reason. If, during the Term, the Company shall terminate Executive’s employment other than for Cause or Disability, or Executive shall terminate his employment for Good Reason, then and with respect to the payments and benefits described in Section 5(a)(i)(B) and (C) and Section 5(a)(ii) and (iii) hereof, only if within sixty (60) days after the Date of Termination Executive shall have executed a separation agreement containing a full general release of claims and covenant not to xxx in a form satisfactory to the Company (the “Release”) and such Release shall not have been revoked within such sixty (60)-day period: (i) the Company shall pay to Executive in a lump sum in cash within sixty (60) days after the Date of Termination (or any later date required by Section 13 hereof) the aggregate of the following amounts: A. the sum of (1) Executive’s Base Salary through the Date of Termination to the extent not theretofore paid, and (2) any accrued vacation pay to the extent not theretofore paid (the sum of the amounts described in clauses (1) and (2) shall be hereinafter referred to as the “Accrued Obligations”); and B. the product of (x) the Severance Cash Ratio multiplied by (y) the sum of (i) Executive’s Annual Base Salary at the rate in effect on the Date of Termination, and (ii) Executive’s Average Annual Performance Bonus; provided, however, that any obligation of the Company to make such payment shall cease upon Executive’s breach of any of his obligations set forth in Section 9 hereof; C. the product of (x) Executive’s Average Annual Performance Bonus and (y) a fraction, the numerator of which is the number of days in the current fiscal year through the Date of Termination, and the denominator of which is 365 (the “Final Year Bonus”); provided, however, that any obligation of the Company to make such payment shall cease upon Executive’s breach of any of his obligations set forth in Section 9 hereof; (ii) if Executive elects to continue participation in any group medical, dental, vision and/or prescription drug plan benefits to which Executive and/or Executive’s eligible dependents would be entitled under Section 4980B of the Code (COBRA), then for twelve (12) months following the Date of Termination (the “Welfare Benefits Continuation Period”), the Company shall pay the excess of (1) the COBRA cost of such coverage over (2) the amount that Executive would have had to pay for such coverage if he had remained employed during the Welfare Benefits Continuation Period and paid the active employee rate for such coverage; provided, however, that (A) that if Executive becomes eligible to receive group health benefits under a program of a subsequent employer or otherwise (including coverage available to Executive’s spouse), the Company’s obligation to pay any portion of the cost of health coverage as described herein shall cease, except as otherwise provided by law; and (B) the Welfare Benefits

Executive further agrees that he shall fully cooperate with the Company in maintaining the Confidential Information to the extent permitted by law. The parties acknowledge and agree that this Agreement is not intended to, and does not, alter either the Company’s rights or Executive’s obligations under any state or federal statutory or common law regarding trade secrets and unfair trade practices. Anything herein to the contrary notwithstanding, Executive shall not be restricted from disclosing information that is required to be disclosed by law, court order or other valid and appropriate legal process; provided, however, that in the event such disclosure is required by law, Executive shall provide the Company with prompt notice of such requirement so that the Company may seek an appropriate protective order prior to any such required disclosure by Executive. (c) Non-Competition. Executive agrees that, during the Employment Period and, if Executive’s employment is terminated during the Term (i) by the Company other than by reason of death or Disability or (ii) by Executive for Good Reason, during the one (1) year period following the Date of Termination, he will not, without prior written consent of the Company, directly or indirectly (a) carry on or engage in Competitive Services within the Restricted Territory on his own or on behalf of any Person or any Principal or Representative of any Person, or (b) own, manage, operate, join, control or participate in the ownership, management, operation or control, of any business, whether in corporate, proprietorship or partnership form or otherwise where such business is engaged in the provision of Competitive Services within the Restricted Territory. (d) Non-Solicitation of Protected Customers. Executive agrees that, during the Employment Period and, if Executive’s employment is terminated during the Term (i) by the Company other than by reason of death or Disability or (ii) by Executive for Good Reason, during the one (1) year period following the Date of Termination, he shall not, without the prior written consent of the Company, directly or indirectly, on his own behalf or as a Principal or Representative

Change of Control Agreement Page 13 LEGAL02/36557583v4 of any Person, solicit, divert, take away, or attempt to solicit, divert, or take away a Protected Customer for the purpose of engaging in, providing, or selling Competitive Services. (e) Non-Recruitment of Employees. Executive agrees that during the Employment Period and, if Executive’s employment is terminated during the Term (i) by the Company other than by reason of death or Disability or (ii) by Executive for Good Reason, during the one (1) year period following the Date of Termination, he shall not, without the prior written consent of the Company, directly or indirectly, whether on his own behalf or as a Principal or Representative of any Person, solicit or induce or attempt to solicit or induce any employee of the Company to terminate his employment relationship with the Company or to enter into employment with Executive or any other Person. (f) Non-Disparagement. Executive agrees that during the Employment Period and, if Executive’s employment is terminated during the Term (i) by the Company other than by reason of death or Disability or (ii) by Executive for Good Reason, during the one (1) year period following the Date of Termination he shall not publicly make or publish, orally or in writing, any derogatory or disparaging statements regarding the Company or its directors, officers, employees of affiliates which are or reasonably may be expected to be injurious or inimical to the business reputation, good will or best interests of the Company or any such persons or affiliates. (g) Enforcement of Restrictive Covenants. (i) Rights and Remedies Upon Breach. The parties specifically acknowledge and agree that the remedy at law for any breach of the Restrictive Covenants will be inadequate, and that in the event Executive breaches, or threatens to breach, any of the Restrictive Covenants, the Company shall have the right and remedy, without the necessity of proving actual damage or posting any bond, to enjoin, preliminarily and permanently, Executive from violating or threatening to violate the Restrictive Covenants and to have the Restrictive Covenants specifically enforced by any court of competent jurisdiction, it being agreed that any breach or threatened breach of the Restrictive Covenants would cause irreparable injury to the Company and that money damages would not provide an adequate remedy to the Company. Executive understands and agrees that if he violates any of the obligations set forth in the Restrictive Covenants, the period of restriction applicable to each obligation violated shall cease to run during the pendency of any litigation over such violation, provided that such litigation was initiated during the period of restriction. Such rights and remedies shall be in addition to, and not in lieu of, any other rights and remedies available to the Company at law or in equity. Executive understands and agrees that, if the parties become involved in legal action regarding the enforcement of the Restrictive Covenants and if the Company prevails in such legal action, the Company will be entitled, in addition to any other remedy, to recover from Executive its reasonable costs and attorneys’ fees incurred in enforcing such covenants. The Company’s ability to enforce its rights under the Restrictive Covenants or applicable law against Executive shall not be impaired in any way by the existence of a claim or cause of action on the part of Executive based on, or arising out of, this Agreement or any other event or transaction. (ii) Severability and Modification of Covenants. Executive acknowledges and agrees that each of the Restrictive Covenants is reasonable and valid in time and scope and in all other respects. The parties agree that it is their intention that the Restrictive Covenants be enforced in accordance with their terms to the maximum extent permitted by law. Each of the Restrictive Covenants shall be considered and construed as a separate and independent

Change of Control Agreement Page 14 LEGAL02/36557583v4 covenant. Should any part or provision of any of the Restrictive Covenants be held invalid, void, or unenforceable, such invalidity, voidness, or unenforceability shall not render invalid, void, or unenforceable any other part or provision of this Agreement or such Restrictive Covenant. If any of the provisions of the Restrictive Covenants should ever be held by a court of competent jurisdiction to exceed the scope permitted by the applicable law, such provision or provisions shall be automatically modified to such lesser scope as such court may deem just and proper for the reasonable protection of the Company’s legitimate business interests and may be enforced by the Company to that extent in the manner described above and all other provisions of this Agreement shall be valid and enforceable. 10. Limitation of Benefits. (a) Anything in this Agreement to the contrary notwithstanding, in the event it shall be determined that any benefit, payment or distribution by the Company to or for the benefit of Executive (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise, but determined without regard to any additional payments required under this Section 10) (such benefits, payments or distributions are hereinafter referred to as “Payments”) would, if paid, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then, prior to the making of any Payments to Executive, a calculation shall be made comparing (i) the net after-tax benefit to Executive of the Payments after payment by Executive of the Excise Tax, to (ii) the net after-tax benefit to Executive if the Payments had been limited to the extent necessary to avoid being subject to the Excise Tax. If the amount calculated under (i) above is less than the amount calculated under (ii) above, then the Payments shall be limited to the extent necessary to avoid being subject to the Excise Tax (the “Reduced Amount”). The reduction of the Payments due hereunder, if applicable, shall be made by first reducing cash Payments and then, to the extent necessary, reducing those Payments having the next highest ratio of Parachute Value to actual present value of such Payments as of the date of the change of control, as determined by the Determination Firm (as defined in Section 10(b) below). For purposes of this Section 10, present value shall be determined in accordance with Section 280G(d)(4) of the Code. For purposes of this Section 10, the “Parachute Value” of a Payment means the present value as of the date of the change of control of the portion of such Payment that constitutes a “parachute payment” under Section 280G(b)(2) of the Code, as determined by the Determination Firm for purposes of determining whether and to what extent the Excise Tax will apply to such Payment. (b) All determinations required to be made under this Section 10, including whether an Excise Tax would otherwise be imposed, whether the Payments shall be reduced, the amount of the Reduced Amount, and the assumptions to be used in arriving at such determinations, shall be made by an independent, nationally recognized accounting firm or compensation consulting firm mutually acceptable to the Company and Executive (the “Determination Firm”) which shall provide detailed supporting calculations both to the Company and Executive within 15 business days of the receipt of notice from Executive that a Payment is due to be made, or such earlier time as is requested by the Company. All fees and expenses of the Determination Firm shall be borne solely by the Company. Any determination by the Determination Firm shall be binding upon the Company and Executive. As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial determination by the Determination Firm hereunder, it is possible that Payments hereunder will have been unnecessarily limited by this Section 10 (“Underpayment”), consistent with the calculations required to be made hereunder. The Determination Firm shall determine the amount of the Underpayment that has occurred and any such Underpayment shall be promptly paid by the Company to or for the benefit of Executive, but

Change of Control Agreement Page 15 LEGAL02/36557583v4 no later than March 15 of the year after the year in which the Underpayment is determined to exist, which is when the legally binding right to such Underpayment arises. 11. Successors. (a) This Agreement is personal to Executive and without the prior written consent of the Company shall not be assignable by Executive otherwise than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by Executive’s legal representatives. (b) This Agreement shall inure to the benefit of and be binding upon the Company and its successors and assigns. (c) The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. As used in this Agreement, “Company” shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which assumes and agrees to perform this Agreement by operation of law, or otherwise. 12. Miscellaneous. (a) Waiver. Failure of either party to insist, in one or more instances, on performance by the other in strict accordance with the terms and conditions of this Agreement shall not be deemed a waiver or relinquishment of any right granted in this Agreement or of the future performance of any such term or condition or of any other term or condition of this Agreement, unless such waiver is contained in a writing signed by the party making the waiver. (b) Severability. If any provision or covenant, or any part thereof, of this Agreement should be held by any court to be invalid, illegal or unenforceable, either in whole or in part, such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of the remaining provisions or covenants, or any part thereof, of this Agreement, all of which shall remain in full force and effect. (c) Status Prior to Effective Date. Executive and the Company acknowledge that, except as may otherwise be provided under any other written agreement between Executive and the Company, the employment of Executive by the Company is “at will” and, subject to Section 1(a) hereof, prior to the Effective Date, Executive’s employment may be terminated by either Executive or the Company at any time prior to the Effective Date, in which case Executive shall have no further rights under this Agreement. However, absent termination of employment of Executive, this Agreement may not be terminated by the Company during the Change of Control Period and before the Effective Date. (d) Governing Law. Except to the extent preempted by federal law, and without regard to conflict of laws principles, the laws of the State of Florida shall govern this Agreement in all respects, whether as to its validity, construction, capacity, performance or otherwise.

Change of Control Agreement Page 16 LEGAL02/36557583v4 (e) Notices. All notices, requests, demands and other communications required or permitted hereunder shall be in writing and shall be deemed to have been duly given if delivered or three days after mailing if mailed, first class, certified mail, postage prepaid: To the Company: To Executive: Seacoast Banking Corporation of Florida 000 Xxxxxxxx Xxxxxx Xxxxxx, Xxxxxxx 00000 Attention: Chief Executive Officer Any party may change the address to which notices, requests, demands and other communications shall be delivered or mailed by giving notice thereof to the other party in the same manner provided herein. (f) Amendments and Modifications. This Agreement may be amended or modified only by a writing signed by both parties hereto, which makes specific reference to this Agreement. (g) Entire Agreement. Except as provided herein, this Agreement contains the entire agreement between the Company and Executive with respect to the subject matter hereof and, from and after the date of this Agreement, this Agreement shall supersede any other agreement between the parties with respect to the subject matter hereof. 13. Code Section 409A. (a) General. This Agreement shall be interpreted and administered in a manner so that any amount or benefit payable hereunder shall be paid or provided in a manner that is either exempt from or compliant with the requirements of Section 409A of the Code and applicable Internal Revenue Service guidance and Treasury Regulations issued thereunder (and any applicable transition relief under Section 409A of the Code). Nevertheless, the tax treatment of the benefits provided under the Agreement is not warranted or guaranteed. Neither the Company nor its directors, officers, employees or advisers shall be held liable for any taxes, interest, penalties or other monetary amounts owed by Executive as a result of the application of Section 409A of the Code. (b) Definitional Restrictions. Notwithstanding anything in this Agreement to the contrary, to the extent that any amount or benefit that would constitute non-exempt “deferred compensation” for purposes of Section 409A of the Code (“Non-Exempt Deferred Compensation”) would otherwise be payable or distributable hereunder, or a different form of payment of such Non- Exempt Deferred Compensation would be effected, by reason of a Change in Control or Executive’s Disability or termination of employment, such Non-Exempt Deferred Compensation will not be payable or distributable to Executive, and/or such different form of payment will not be effected, by reason of such circumstance unless the circumstances giving rise to such Change in Control, Disability or termination of employment, as the case may be, meet any description or definition of “change in control event”, “disability” or “separation from service”, as the case may be, in Section 409A of the Code and applicable regulations (without giving effect to any elective

Change of Control Agreement Page 17 LEGAL02/36557583v4 provisions that may be available under such definition). This provision does not affect the dollar amount or prohibit the vesting of any Non-Exempt Deferred Compensation upon a Change in Control, Disability or termination of employment, however defined. If this provision prevents the payment or distribution of any Non-Exempt Deferred Compensation, or the application of a different form of payment, such payment or distribution shall be made at the time and in the form that would have applied absent the non-409A-conforming event. (c) Six-Month Delay in Certain Circumstances. Notwithstanding anything in this Agreement to the contrary, if any amount or benefit that would constitute Non-Exempt Deferred Compensation would otherwise be payable or distributable under this Agreement by reason of Executive’s separation from service during a period in which he is a Specified Employee (as defined below), then, subject to any permissible acceleration of payment by the Company under Treas. Reg. Section 1.409A-3(j)(4)(ii) (domestic relations order), (j)(4)(iii) (conflicts of interest), or (j)(4)(vi) (payment of employment taxes): (i) the amount of such Non-Exempt Deferred Compensation that would otherwise be payable during the six-month period immediately following Executive’s separation from service will be accumulated through and paid or provided on the first day of the seventh month following Executive’s separation from service (or, if Executive dies during such period, within 30 days after Executive’s death) (in either case, the “Required Delay Period”); and (ii) the normal payment or distribution schedule for any remaining payments or distributions will resume at the end of the Required Delay Period. For purposes of this Agreement, the term “Specified Employee” has the meaning given such term in Code Section 409A and the final regulations thereunder. (d) Treatment of Installment Payments. Each payment of termination benefits under Section 5 of this Agreement shall be considered a separate payment, as described in Treas. Reg. Section 1.409A-2(b)(2), for purposes of Section 409A of the Code. (e) Timing of Release of Claims. Whenever in this Agreement a payment or benefit is conditioned on Executive’s execution of a separation agreement including a release of claims, such separation agreement including the release must be executed and all revocation periods shall have expired within 60 days after the date of termination or resignation; failing which such payment or benefit shall be forfeited. If such payment or benefit constitutes Non-Exempt Deferred Compensation, then, subject to Section 13(c) above, such payment or benefit (including any installment payments) that would have otherwise been payable during such 60-day period shall be accumulated and paid on the 60th day after the date of termination or resignation provided such separation agreement including the release shall have been executed and such revocation periods shall have expired. If such payment or benefit is exempt from Section 409A of the Code, the Company may elect to make or commence payment at any time during such 60-day period. (f) Timing of Reimbursements and In-kind Benefits. If Executive is entitled to be paid or reimbursed for any taxable expenses under Sections 3(b)(v) and (vi) or Section 5(a)(ii), and such payments or reimbursements are includible in Executive’s federal gross taxable income, the amount of such expenses reimbursable in any one calendar year shall not affect the amount reimbursable in any other calendar year, and the reimbursement of an eligible expense must be made no later than December 31 of the year after the year in which the expense was incurred. No right of Executive to reimbursement of expenses under Sections 3(b)(v) and (vi) or Section 5(a)(ii) shall be subject to liquidation or exchange for another benefit.

Change of Control Agreement Page 18 LEGAL02/36557583v4 (g) Permitted Acceleration. The Company shall have the sole authority to make any accelerated distribution permissible under Treas. Reg. Section 1.409A-3(j)(4) to Executive of deferred amounts, provided that such distribution meets the requirements of Treas. Reg. Section 1.409A-3(j)(4).
