ITEM 2.           OTHER EVENTS.

                  At the close of business on May 30, 1997, Seacoast Banking
Corporation of Florida ("Seacoast") consummated the acquisition (the "Merger")
of Port St. Lucie National Bank Holding Corp. ("PSHC") pursuant to the terms of
that certain Agreement and Plan of Merger (the "Merger Agreement"), dated as of
February 19, 1997 by and between Seacoast and PSHC. In addition, Port St. Lucie
National Bank, the wholly-owned banking subsidiary of PSHC, was merged with and
into the First National Bank & Trust Company of the Treasure Coast ("FNB"), the
wholly-owned banking subsidiary of Seacoast. It is anticipated that Messrs.
Jeffrey S. Furst and Christopher E. Fogal, previously directors of PSHC, will
become members of the Seacoast and the FNB Boards of Directors.

                  Pursuant to the terms of the Merger Agreement, each share of
common stock, par value $.01 per share, of PSHC ("PSHC Common Stock") issued and
outstanding at the effective time of the Merger (the "Effective Time") was
converted into the right to receive 1.00337 shares of the Class A common stock,
par value $.10 per share, of Seacoast ("Seacoast Class A Stock"). In addition,
each issued and outstanding warrant to purchase shares of PSHC Common Stock
("PSHC Warrants") at the Effective Time was converted into the right to receive
0.67680 shares of Seacoast Class A Stock. These ratios of exchange were
determined in accordance with the formulae set forth in the Merger Agreement,
which are dependent on the market price of Seacoast Class A Stock during a
20-day pricing period prior to the Effective Time of the Merger. Each holder of
shares of PSHC Common Stock exchanged pursuant to the Merger who was otherwise
entitled to receive a fraction of a share of Seacoast Class A Stock received
cash-in-lieu of such fractional shares at a price of $25.29375 per share of
Seacoast Class A Stock. Each PSHC stock option issued and outstanding as of the
Effective Time of the Merger was assumed by Seacoast and converted into the
right to purchase shares of Seacoast Class A Stock, adjusted to reflect the PSHC
Common Stock conversion ratio. An aggregate of 50,988 shares of Seacoast Class
A Stock are issuable upon exercise of such options.

ITEM 5.           OTHER EVENTS

Amendment and Restatement of Articles of Incorporation

                  At a meeting of the Board of Directors of Seacoast duly called
and convened on April 15, 1997, the Board of Directors ratified, adopted and
approved an amendment to the Seacoast Articles of Incorporation to clarify the
voting requirement in connection with certain business combinations (as it
appears below in its entirety, the "Amendment").

                  The Amendment was required to be adopted and approved by the
holders of shares of the common stock of Seacoast voting in accordance with the
Seacoast Articles of Incorporation. At the Seacoast Meeting, the Amendment was
duly adopted and approved in accordance with voting provisions contained in the
Articles of Incorporation of Seacoast. 
   3

                  Pursuant to the approval and adoption of the Amendment,
Article XI of the Seacoast Articles of Incorporation now reads in its entirety
as follows:

                                   "ARTICLE XI
                MERGER, CONSOLIDATION OR BUSINESS COMBINATION

                  The affirmative vote of the holders of two-thirds (66 2/3%)
         of all the shares of Class A Common Stock outstanding and entitled to
         vote, voting as a separate class, and the affirmative vote of the
         holders of shares with two-thirds (66 2/3%) of all the votes
         entitled to be cast by all shares of Common Stock of all classes
         outstanding, voting together as a single class, shall be required to
         approve any of the following:

                           (a) any merger or consolidation of this corporation
                  with or into any other corporation;

                           (b) any share exchange in which a corporation,
                  person, or entity acquires the issued or outstanding shares of
                  stock of this corporation pursuant to a vote of stockholders;

                           (c) any sale, lease, exchange or other transfer of
                  all, or substantially all, of the assets of this corporation
                  or any significant subsidiary of this corporation to any other
                  corporation, person or entity;

                           (d) any transaction similar to, or having a similar
                  affect on, any of the foregoing transactions.

                  Such affirmative votes shall apply and be required whether or
         not a vote of the stockholders otherwise would be required by law or
         the rules of any securities exchange or market (collectively, an "SRO")
         on which this corporation has shares of its capital stock listed or
         traded and notwithstanding that a lesser vote of stockholders might
         otherwise be required by law or SRO; provided, however no such
         affirmative votes shall be required where this corporation is issuing
         shares of its capital stock or paying cash or other consideration to
         acquire, directly or indirectly, another corporation, person or
         entity."

                  The Amendment became effective upon the close of business May
30, 1997.

Amendment and Restatement of Bylaws

                  At a meeting of the Board of Directors of Seacoast (the
"Board") duly called and convened on May 20, 1997, the Board ratified, approved
and adopted an amendment to Bylaws of Seacoast to provide that the number of
directors of Seacoast shall be between five (5) and fourteen (14), as the Board
shall determine from time to time. Article III, Section 2 of the Bylaws of
Seacoast was amended to read in its entirety as follows:

         "2.      NUMBER, TENURE AND QUALIFICATIONS

                  The number of directors of the Corporation shall be determined
         from time to time by the Board of Directors pursuant to a resolution
         duly adopted by the Board of Directors, but in no event shall the
         Corporation have less than five (5) directors nor more than fourteen
         (14) directors. The number of directors may also be changed by the
         Shareholders from time to time by amendment to these Bylaws, but no
         decrease in the number of directors shall have the effect of shortening
         the term of any such incumbent director. Each director shall hold
         office until the next annual meeting of stockholders and until his
         successor shall have been elected and qualified."

                  On May 20, 1997 the Bylaws of Seacoast were amended and
restated to reflect the amendment as it appears above.
