this 19th day of February 1997, by and among J. Hal Roberts, Jr. ("Executive"),
the First National Bank and Trust Company of the Treasure Coast (the "Bank") and
the Bank's parent corporation, Seacoast Banking Corporation of Florida (the

Executive desires to serve in such positions; and
 
     WHEREAS, in order to provide adequate assurances to Executive as an

full time best efforts to the Bank and the Company.
 
     NOW, THEREFORE, in consideration of the mutual covenants and conditions
herein contained, and other good and valuable consideration, the receipt and

another executive position with the Company or its subsidiaries, including the
Bank, or Executive's employment may be terminated pursuant to Section 4(c)
hereof by action of the Board of Directors of the Bank prior to a Change in
Control and that such a change in position, duties, responsibilities, powers or
a termination of employment pursuant to Section 4(c) hereof whether prior to or
following a Change in Control shall not entitle Executive to the benefits
provided for in Section 5(c), unless such change or termination is not made in
good faith.
 
     (b) Company.  The Company shall employ Executive as Executive Vice
President of the Company with the duties, responsibilities and powers of such

Executive may be changed to another executive position with the Company or its
subsidiaries, including the Bank, or Executive's employment may be terminated
pursuant to Section 4(c) hereof by action of the Board of Directors of the
Company prior to a Change in Control and that such a change in position, duties,
responsibilities, powers or a termination of employment pursuant to Section 4(c)
hereof whether prior to or following a Change in Control shall not entitle
Executive to the benefits provided for in Section 5(c), unless such change or
termination is not made in good faith.
 
     (c) Executive represents, warrants and covenants to the Bank and the
Company that he will be available to commence his duties hereunder immediately
at the Effective Time of the Merger (as defined in Section 2 hereof) and that
this Agreement and his performance of services hereunder does not breach or
conflict with any other agreements or instruments to which Executive is a party
or may be bound, and that he shall faithfully and diligently discharge his
duties and responsibilities under this Agreement, and shall use his best
   2
 
efforts to implement the policies established by the Board of Directors and the
Chief Executive Officer of the Bank and the Company, respectively.
 
     (d) During the term of this Agreement, Executive shall devote his full and
exclusive business time, energy and skill to the businesses of the Bank and the
Company, to the promotion of the interests of the Bank and the Company and to
the fulfillment of Executive's obligations hereunder.
 
2. TERM
 
     This Agreement will become effective (the "Effective Date") immediately
prior to the Effective Time of the merger of Port St. Lucie National Bank
Holding Corporation with and into Seacoast Banking Corporation of Florida (the
"Merger"). The term of this Agreement shall be three (3) years from the
Effective Date, unless further extended by mutual consent of the Bank, the
Company and Executive or sooner terminated as herein provided. Unless 90 days'
prior notice of nonrenewal is given by the Executive, the Bank or the Company
prior to the end of the initial and any subsequent term hereof, this Agreement
shall automatically be renewed on the expiration of the initial term and
annually thereafter through the next succeeding anniversary of this Agreement.
 
     Executive hereby voluntarily terminates and surrenders any rights Executive
may have under any employment, change in control, severance or similar agreement
or understanding, whether written or oral between Executive and Port St. Lucie
National Bank Holding Corporation or any of its affiliates.
 
3.  COMPENSATION AND BENEFITS
 
     The Bank shall pay or provide to Executive the following items as
compensation for his services hereunder:
 
          (i) A base salary of $150,000 per year, payable in monthly
     installments, which base salary may be increased from time to time in
     accordance with normal business practices of the Bank; and
 
          (ii) A grant of stock options to purchase 9,000 shares of Company
     Class A Common Stock under the Company's 1996 Long-term Incentive Plan (the
     "1996 Plan") with an exercise price per share equal to the "fair market
     value" of one share of Company Common Stock on the date that the options
     are granted. Fair market value shall be determined with respect to the
     closing "asked" price of the shares in the over-the-counter market on the
     day on which such value is to be determined (or as otherwise specified in
     the 1996 Plan). Such options will vest ratably over four years. Such grant
     will be made concurrently with the Company's next regularly scheduled grant
     of stock options, and not later than 60 days after the Effective Date.
 
          (iii) Hospitalization insurance (including major medical), long-term
     disability insurance, and life insurance in accordance with the Bank's
     insurance plans for senior management and their dependents as such plans
     may provide and may be modified from time to time; and
 
          (iv) Reasonable club dues.
 
     The above-stated terms of compensation shall not be deemed exclusive or
prevent Executive from receiving any other compensation, including, without
limitation, bonuses, provided by the Bank and/or the Company. Executive shall be
entitled to participate in all current and future employee benefit plans and
arrangements in which the senior management of the Bank is permitted to
participate. The Company does not separately compensate its officers who are
also officers of the Bank and no additional compensation will be payable by the
Company hereunder.

4.  TERMINATION
 
     Executive's employment under this Agreement shall terminate:
 
     (a) Death.  Upon Executive's death; or
 
     (b) Disability.  Upon notice from the Bank to Executive in the event
Executive becomes "permanently disabled." For purposes of this Agreement,
Executive shall be deemed "permanently disabled" if he has been disabled by
bodily or mental illness, disease, or injury, to the extent that, in the opinion
of the Board of Directors, he is prevented from performing his material and
substantial duties of employment, and provided further that such disability has
continued substantially for six (6) months preceding such notice. If requested
by the Bank, Executive shall submit to an examination by a physician selected by
the Bank for the purpose of determining or confirming the existence or extent of
any disability; or
 
     (c) Cause.  Upon notice from the Bank to Executive for cause. For purposes
of this Agreement, "cause" shall be (i) a willful and continued failure by
Executive to perform his duties as President/St. Lucie County of the Bank and
Executive Vice President of the Company as established by their respective
Boards of Directors (other than due to disability), or (ii) a breach by
Executive of his fiduciary duties of loyalty or care to the Bank or the Company,
or (iii) a willful violation by Executive of any provision of this Agreement, or
(iv) a conviction or the entering of a plea of nolo contendere by Executive for
any felony or any crime involving fraud, dishonesty or a breach of trust, or (v)
a breach of the Bank's Code of Ethics, or (vi) commission by Executive of a
willful or negligent act which causes material harm to the Bank or the Company,
or (vii) habitual absenteeism, alcoholism or other form of drug or other
addiction, or (viii) any violation of laws or regulations such that Executive
ceases to be eligible to serve as an executive officer of a depository
institution or a depository institution holding company or (ix) Executive
becomes ineligible to be bonded at costs consistent with the Bank and/or the
Company's other senior officers. In addition, if Executive shall terminate his
employment for a breach of this Agreement by the Bank in accordance with Section
4(e), and it is ultimately determined that no reasonable basis existed for
Executive's termination on account of the alleged default of the Bank and/or the
Company, such event shall be deemed cause for termination by the Bank.
 
     Any notice of termination of Executive's employment with the Bank or the
Company for cause shall set forth in reasonable detail the facts and
circumstances claimed to provide the basis for termination of his employment
under the provisions contained herein and the effective date of termination
("Termination Date"); or
 
     (d) Change in Control.  Upon notice by Executive to the Bank or the Company
following a "Change in Control" (as defined in this Section 4(d)), provided
Executive terminates his employment within one (1) year following the effective
date of such Change in Control. For purposes of this Agreement, a "Change in
Control" shall be deemed to have occurred if (i) the Bank or Company shall
become a direct or indirect subsidiary of, or shall be merged or consolidated
with or into, another entity, which entity is neither controlled by the Company
nor the Bank or if 51% or more of the voting power of shares of (x) Class A
Common Stock, (y) Class B Common Stock or (z) the shares of Class A and Class B
Common Stock voting together as one class, of the resulting entity are not held
by persons who were shareholders of the Company or Bank immediately before the
transaction, subject to the limitations of subparagraph (iii) below; or (ii)
substantially all of the assets of the Company or Bank shall be sold or
transferred to a person or entity, which person or entity is neither controlled
by the Bank nor Company or if 51% or more of the voting power of shares of (x)
Class A Common Stock, (y) Class B Common Stock or (z) the shares of Class A and
Class B Common Stock voting together as one class are not held by persons who
were shareholders of the Bank or Company immediately prior to the asset sale,
subject to the limitations of subparagraph (iii) below; or (iii) any "person"
(as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act
of 1934), or persons acting together or in concert, and who are not at the date
hereof beneficial owners (individually or collectively) of 10% or more of the
common stock of the Company or the Bank of any class or series become the
"beneficial owner" (as defined in Rule 13(d) of the Securities Exchange Act of
1934 as amended) of securities of the Bank or the Company representing 45% or
more of the voting power of either any individual class of securities
 
                                        3
   4
 
or of any classes which vote together of the Bank's or Company's then
outstanding securities, other than a trustee or other fiduciary holding
securities under an employee benefit plan of the Company or Bank; or
 
     (e) Breach.  Upon notice from Executive to the Bank and/or the Company of
the Bank's and/or the Company's failure to comply with any material provision of
this Agreement, provided that the Bank or the Company, as the case may be, shall
have thirty (30) days from the receipt of such notice to cure any such failure
under this Agreement. If such failure shall be cured or if the Bank shall have
taken steps to cure the failure within the thirty (30) day period, Executive
shall have no right to terminate his employment under the provisions of this
Section 4(e); or
 
     (f) Change in Position or Duties.  Upon notice from Executive to the Bank
and/or the Company in the event Executive is not elected President/St. Lucie
County and Executive Vice President of the Bank and the Company, respectively,
with the duties and powers which are customarily associated with such office;
provided that any change in Executive's title that results from a general
restructuring of the Bank's or Company's title structure shall not result in any
consequence under this Section 4(f); or
 
     (g) Improper Termination by Company.  Upon notice from Executive to the
Bank and/or the Company, as applicable, upon a purported termination of
Executive's employment by the Bank and/or the Company for cause, if it is
ultimately determined that cause did not exist; or
 
     (h) Expiration of Term.  Upon the expiration of the term of this Agreement
as set forth in Section 2.
 
5.  COMPENSATION AND BENEFITS PAYABLE UPON TERMINATION
 
     (a) Upon Executive's death, the Bank shall pay Executive's full base salary
in accordance with the terms set forth in Section 5(c) below. In addition, the
Bank shall continue to pay for and provide to Executive's spouse and eligible
dependents hospitalization insurance (including major medical), and any such
other health insurance benefits comparable to that coverage that would have been
provided under the Bank's group health insurance plan to Executive's spouse and
eligible dependents at the date of Executive's death, at such time in accordance
with the terms set forth in Section 5(c).
 
     (b) In the event Executive becomes permanently disabled and is terminated
as set forth in Section 4(b) above, the Bank shall pay to Executive compensation
and benefits as set forth in Section 5(c) below, provided that Executive's base
salary shall be reduced by any amounts received by Executive under the Bank's
long term disability plan or from any other collateral source payable due to
disability, including, without limitation, social security benefits. If
Executive shall remain permanently disabled beyond the period set forth in
Section 5(c) below, Executive shall receive only such amounts, if any, as are
payable under the Bank's long term disability plan or under any other employee
benefit or welfare plan in which Executive participated and is entitled to
benefits.
 
     (c) If Executive's employment shall be terminated by Executive pursuant to
Sections 4(d), (e), (f) or (g), or by the Bank for any reason other than for
cause as set forth in Section 4(c), the Bank shall continue to pay to Executive
or his estate or beneficiaries his full base salary (including any other cash
compensation) to which Executive would be entitled at the Termination Date or on
the date of a Change in Control, whichever date will result in the greater base
salary, for a period of two (2) years following the Termination Date. In
addition, the Bank shall continue to pay his and his dependents' (to the extent
provided in Section 3(iii) hereof, hospitalization insurance premiums (including
major medical), long term disability premiums and life insurance premiums for a
period of two (2) years or until his earlier death. The compensation and
benefits payable under this Section 5(c) are hereinafter referred to as
"Severance Benefits."
 
     The payment of Severance Benefits is in recognition and consideration of
the continued services by Executive to the Bank and the Company and is not in
any way to be construed as a penalty or damages. Executive shall not be required
to mitigate the amount of any payment of Severance Benefits by seeking other
employment or otherwise. The payment of Severance Benefits shall not affect any
other sums or benefits otherwise payable to Executive under any other employment
compensation or benefit or welfare plan of the Bank.
 
                                        4
   5
 
     (d) In the event termination is for any reason other than as described in
Section 5(a), (b), or (c) above, the Bank shall pay Executive his full salary
through the date of termination and no other compensation or benefits shall be
paid to Executive hereunder; provided, however, that nothing herein shall be
deemed to limit his vested rights under any other benefit, retirement, stock
option or pension plan of the Bank, and the terms of those plans, programs, or
arrangements shall govern.
 
6.  NONCOMPETITION AND NONDISCLOSURE
 
     (a) To induce the Bank and the Company to enter into this Agreement,
Executive agrees that during the term of this Agreement and for a period of two
(2) years after the termination of employment or service of Executive hereunder,
Executive will not, within Martin, Indian River or St. Lucie Counties, Florida
or any other county wherein the Bank, the Company and/or the Company's direct or
indirect subsidiaries conduct business at the date his employment is terminated,
as principal, agent, trustee or through the agency or on behalf of any
corporation, partnership, association, trust or agent or agency, (i) engage in
the business of banking, fiduciary services, securities brokerage, investment
management or services, lending or deposit taking, (ii) control or own
beneficially (directly or indirectly) 5% or more of the outstanding capital
stock or other ownership interest (a "Principal Stockholder") of any corporation
or person engaged in or controlling any such business other than the Company or
Bank, or (iii) serve as an officer, director, trustee, agent or employee of any
corporation, or as a member, employee or agent of any partnership, or as an
owner, trustee, employee or agent of any other business or entity, which
directly or indirectly conducts such business within Martin, Indian River or St.
Lucie Counties, Florida, or any other county wherein the Bank, the Company
and/or the Company's direct or indirect subsidiaries conduct business at the
date his employment is terminated. Executive further agrees that during the term
of this Agreement and for a period of two (2) years after the termination of
employment or service of Executive hereunder, Executive will not solicit any
employee to leave their employment with the Company or Bank or any Company or
Bank subsidiaries for any reason or otherwise interfere with the employment
relationship of the Company, the Bank and such subsidiaries with any employee.
For purposes of this Agreement, it shall be presumed that Executive has
solicited such an employee or interfered with such employee relationships of the
Company, the Bank, or their subsidiaries if Executive serves as an officer,
director, trustee, managing agent or as a Principal Stockholder of any person or
entity which hires or seeks or negotiates the employment or hiring of any such
employee as an officer or other management official or consultant. In the event
that the provisions of this Section 6(a) should be deemed to exceed the time or
geographic limitations permitted by applicable law, then such provisions shall
be reformed automatically to the maximum time or geographic limitations so
permitted. The foregoing notwithstanding, Executive may engage in activities on
behalf of civic, community and charitable nonprofit organization after
termination of employment, and may manage the assets of any such organization
not engaged in the businesses set forth in this Section 6(a).
 
     (b) Executive recognizes and acknowledges that he will have access to
certain confidential information of the Company, the Bank and of their
subsidiaries and affiliates, including, without limitation, customer lists,
information regarding customers, confidential methods of operation, lending,
credit information, organization, pricing, mark-ups, commissions and other
information and that all such information constitutes valuable, special and
unique property of the Company, Bank and their subsidiaries and affiliates. Such
information is herein referred to as "Trade Secrets". The term Trade Secret
shall not include information which is or becomes generally available to the
public other than as a result of a disclosure by Executive or representatives,
agents or affiliates of Executive. Executive will not disclose or directly or
indirectly utilize in any manner, including without limitation to solicit any
customer of the Company, the Bank or their affiliates, except family members of
Executives, any such Trade Secrets for his own benefit or the benefit of anyone
other than the Company, Bank and their subsidiaries and affiliates during the
term of this Agreement and for a period of two (2) years after the term of this
Agreement. In the event of a breach or threatened breach by Executive of the
provisions of this Section 6(b), the Company, the Bank, or any subsidiary or
affiliate of the Company or the Bank shall be entitled to an injunction
restraining Executive and any others from disclosing or utilizing, in whole or
in part, such Trade Secrets. Nothing herein shall be construed as prohibiting or
limiting the Company, Bank, or any subsidiary or affiliate of the Company or the
Bank from exercising any other available
 
                                        5
   6
 
rights or remedies for such breach or threatened breach, including, without
limitation, the recovery of damages from Executive or others.
 
     In the event that Executive is requested or required (by oral questions,
interrogatories, requests for information or documents in legal proceedings,
subpoena, civil investigative demand or other similar process) to disclose any
of the Trade Secrets, Executive shall provide the Company with prompt written
notice of any such request or requirement so that the Company may seek a
protective order or other appropriate remedy and/or waive compliance with the
provisions of this agreement. If, in the absence of a protective order or other
remedy or the receipt of a waiver by the Company, Executive is nonetheless, in
the written opinion of counsel, legally compelled to disclose Trade Secrets to
any tribunal or else stand liable for contempt or suffer other censure or
penalty, Executive may, without liability hereunder, disclose to such tribunal
only that portion of the Trade Secrets which such counsel advises Executive is
legally required to be disclosed, provided that Executive exercises his best
efforts to preserve the confidentiality of the Trade Secrets, including, without
limitation, by cooperating with the Company to obtain an appropriate protective
order or other reliable assurance that confidential treatment will be accorded
the Trade Secrets by such tribunal.
 
7.  ARBITRATION
 
     Any dispute or controversy arising under or in connection with this
Agreement other than as a result of the provisions of Section 6 hereof shall be
settled exclusively by arbitration. Each party shall appoint one arbitrator and
shall notify in writing the other party of such appointment and request the
other party to appoint one arbitrator within thirty (30) days of receipt of such
request. If the party so requested fails to appoint an arbitrator, the party
making the request shall be entitled to designate two arbitrators. The two
arbitrators shall select a third. The written decision of a majority of the
arbitrators shall be binding upon the Bank and Executive and enforceable by law.
The arbitrators shall, by majority vote, determine the place for hearing, the
rules of procedure, and allocation of the expenses of the arbitration. Absent
any written agreement to the contrary, the rules of the American Arbitration
Association shall apply to any arbitration proceedings.
 
8.  APPLICATION OF CODE SECTION 280G
 
     If any payment of Severance Benefits hereunder shall be determined to be an
"excess parachute payment" as defined by Section 280G of the Internal Revenue
Code of 1986, as amended (the "Code"), which subjects Executive to an excise tax
under Section 4999(a) of the Code, the Bank shall pay a supplemental benefit
equal to the excise tax and all state and federal income taxes on the
supplemental benefit. Executive agrees to fully cooperate with the Bank should
the Bank determine to challenge, for whatever reason, any determination by the
Internal Revenue Service that Severance Benefits paid hereunder constitute
"excess parachute payments" as defined by Section 280G of the Code.
 
9.  SUCCESSORS, BINDING AGREEMENT
 
     (a) This Agreement shall be binding upon 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 Bank or the Company
regardless of whether such occurrence constitutes a Change in Control hereunder
and the Bank and the Company shall require any such successor to expressly
assume and agree to perform this Agreement. As used in this Agreement, "Company"
and "Bank" shall mean the Company and the Bank as herein respectively defined
and any successors or assigns to their respective business and/or assets as
aforesaid which is required by this Agreement to assume and perform this
Agreement, whether by operation of law or otherwise. In the event any successor
to the Company has total assets in excess of $8 billion and does not maintain a
Florida-based holding company, then the term "successor" shall only include the
bank resulting from such transaction.
 
     (b) This Agreement shall inure to the benefit of and be enforceable by
Executive's personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees. If Executive should die
while any amount would still be payable hereunder, all such amounts, unless
otherwise provided
 
                                        6
   7
 
herein, shall be paid in accordance with the terms of this Agreement to
Executive's devisee, legatee or other designee or, if there is no such designee,
to Executive's estate.

full force and effect.
 
     (c) The failure of the parties to complain of any act or omission on the
part of either party, no matter how long the same may continue, shall not be

which shall be deemed an original, but all of which shall constitute one and the
same instrument. It may be modified or terminated only by a writing signed by
the party against whom enforcement of any waiver, change, modification,
extension, discharge or termination is sought.
 
     (e) The recitals contained in this Agreement are expressly made a part
hereof.
 
     (f) This Agreement represents the entire understanding and agreement among
the parties and supersedes any prior agreements or understandings with respect

Agreement and may enforce the provisions hereof to the same extent as the Bank.

                            FORM OF FAIRNESS OPINION
    
 
                                 March 25, 1997
 
   
Board of Directors
    
Port St. Lucie National Bank Holding Corp.
1100 S.W. St. Lucie W. Blvd.
Port St. Lucie, FL 34996
 
Members of the Board:
 
     You have requested our opinion as to the fairness, from a financial point
of view, to Port St. Lucie National Bank Holding Corp. ("PSHC") and its
shareholders of terms of the Agreement and Plan of Merger dated February 19,
1997 ("Agreement") by and between Seacoast Banking Corporation of Florida
("Seacoast") and PSHC. The Agreement provides for the merger of PSHC with and
into Seacoast (the "Merger").
 
     The terms of the Agreement provide for the aggregate issuance of 900,000
shares of Seacoast Class A Common Stock to PSHC common shareholders, option
holders and warrant holders (collectively referred to as "shareholders"). The
exchange ratio to PSHC common shareholders (the "Stock Exchange Ratio") shall be
determined by dividing the Purchase Price Per Share by the Seacoast Stock Price,
both terms being defined in the Agreement. PSHC options will be convened into
the right to purchase Seacoast Common Stock, adjusted for the Stock Exchange
Ratio. The exchange ratio to warrant holders (the "Warrant Exchange Ratio")
shall be determined by dividing (i) the difference between the Purchase Price
Per Share and $8.26 (the exercise price for all warrants) by (ii) the Seacoast
Stock Price. PSHC has the right to terminate the transactions the Purchase Price
Per Share is less than $24.62.
 
     In carrying out our engagement, we have reviewed and analyzed material
bearing upon the financial and operating condition of PSHC and Seacoast
including but not limited to the following: (i) the audited financial statements
of PSHC and Seacoast for the period 1991 through 1996; (ii) the reported prices
and stock trading activity of PSHC and Seacoast; (iii) publicly available
information regarding the performance of certain other companies whose business
activities were, believed to be generally comparable to those of PSHC and
Seacoast; (iv) the financial terms, to the extent publicly available, of certain
comparable bank merger transactions; (v) the strategic objectives of the Merger
and the synergies and other benefits of the Merger for the combined company as
described by senior management of PSHC and Seacoast; and (vi) such other
analysis and information as we deemed relevant.
 
     In our review and analysis, we relied upon and assumed the accuracy and
completeness of the financial and other information provided to us or publicly
available, and have not attempted to verify the same. We have made no
independent verification as to the assets or properties of PSHC or Seacoast, and
have instead relied upon representations and information of PSHC and Seacoast,
in the aggregate. In rendering our opinion, we have assumed that the transaction
will be a tax-free reorganization with no material adverse tax consequences to
PSHC or Seacoast, or to PSHC shareholders. We have assumed in the course of
obtaining the necessary regulatory approvals for the transaction, no condition
will be imposed that will have a material adverse effect on the contemplated
benefits of the transaction to PSHC and its shareholders.
 
     Austin Associates participated in discussions and negotiations with
representatives of PSHC and Seacoast and their financial and legal advisors. For
our services, including the rendering of this opinion, PSHC will pay us a fee
and indemnify us against certain liabilities, including liabilities under the
securities laws.
 
     We consent to the use of this opinion in the Joint Proxy
Statement/Prospectus which is a part of Seacoast's Registration Statement on
Form S-4.

     Based upon our analysis and subject to the qualifications described herein,
we believe that, as of the date of this letter, the terms of the Merger are
fair, from a financial point of view, to PSHC and its shareholders.
