EXHIBIT 99.03

                                    AGREEMENT

         THIS AGREEMENT, is entered into on February 7, 2003 by the ST. JOE
COMPANY ("St. Joe") and the ALFRED I. DUPONT TESTAMENTARY TRUST and THE NEMOURS
FOUNDATION (collectively, the "Trust").

                                    RECITALS

I.       St. Joe's Board of Directors has authorized an open market stock
         repurchase program (the "Stock Repurchase Program") for the purchase of
         shares of St. Joe's outstanding common stock, no par value ("Shares").

II.      The Trust desires to sell Shares to St. Joe, and St. Joe desires to
         purchase Shares from the Trust, in connection with the Stock Repurchase
         Program as provided in this Agreement.

III.     This Agreement is being entered into in good faith and not as part of a
         plan or scheme to evade the prohibitions of Rule 10b5-1 under the
         Securities Exchange Act of 1934, as amended (the "1934 Act").

         IN CONSIDERATION OF the mutual promises contained in this Agreement,
St. Joe and the Trust agree:

A.       Purchase and Sale

1.       St. Joe shall deliver to the Trust a completed notice in the form
         attached to this Agreement as Exhibit "A" (a "Notice") at or before
         12:00 p.m. Eastern Time each Monday or, if Monday is not a business
         day, on the next business day. The Trust shall, after receipt of the
         Notice, deliver and sell to St. Joe, and St. Joe shall buy from the
         Trust (each such transaction, a "Sale"), at or before 12:00 p.m.
         Eastern Time on the third business day following receipt of the Notice
         (a "Closing Date") a number of shares equal to 0.9, multiplied by the
         aggregate number of Shares St. Joe has purchased on the open market
         from persons other than the Trust during the calendar week ending
         immediately prior to the date of the relevant Notice (the "Prior Week
         Shares"). On each Closing Date, (a) the Trust shall deliver to St.
         Joe's transfer agent stock instructions to transfer the Prior Week
         Shares to St. Joe, together with such stock powers and other
         instruments as may be necessary to give effect to such instructions,
         and (b) St. Joe shall pay the purchase price for the Prior Week Shares
         in



         immediately available funds to such account as the Trust has designated
         in writing.

         2.       The price per Share to be paid by St. Joe under each Sale
                  shall be the Volume Weighted Average Price ("VWAP") paid by
                  St. Joe for the Prior Week Shares. For purposes of this
                  Agreement, VWAP is calculated by dividing the total
                  consideration paid, without taking commissions into account,
                  for the Prior Week Shares by the Prior Week Shares, excluding
                  any transaction involving the purchase of shares directly from
                  affiliates of St. Joe. An example of the calculation of VWAP
                  is set forth in the schedule attached to this Agreement as
                  Exhibit "B". The price shall be set forth in Item 3 of the
                  Notice.

         3.       The Trust shall not be required to effect any Sale if the
                  price for the Shares is less than $27.00 per Share. St. Joe
                  shall not be obligated to deliver a Notice and neither St. Joe
                  nor the Trust shall be required to effect a Sale if the
                  performance of their respective obligations would violate
                  applicable law. Only one Notice may be delivered and one Sale
                  may be effected each week.

         4.       Any fractional amounts of Shares required to be sold to St.
                  Joe under any Notice shall be rounded up to the nearest whole
                  number.

         5.       For purposes of this agreement, (a) "business day" means a day
                  on which the New York Stock Exchange is open for trading, and
                  (b) "affiliate" has the meaning given it in Rule 12b-2 under
                  the 1934 Act.

B.       Term. The initial term of this Agreement shall commence on February 10,
         2003 and shall continue for ninety (90) days. The parties, by mutual
         agreement, may renew this Agreement for additional terms of ninety (90)
         days each, subject to mutual agreement on the floor price in Section A
         (3) with respect to such renewal period. It is the intent of the
         parties that the Trust participate in the Stock Repurchase Program on a
         pro rata basis with the public shareholders. Accordingly, the parties
         agree that upon renewal the multiplier contained in Section A (1), i.e.
         "0.9", will be adjusted, if necessary, to properly account for the then
         current ownership position of the Trust and the public shareholders.

                  the purchase price therefor, pass valid title to St. Joe to
