Section 4 of the Jacksonville Terminal Agreement, contained in Section 5.7 of the Schedules and Exhibits to the SPC Agreement, is amended by replacing "five (5) years" with "two (2) years". 4. Escrow Fund. Purchaser agrees that an Escrow Fund shall not be required and no portion of the Aggregate Purchase Price shall be paid as described in Section 2.3.1 of the SPC Agreement. To that end, the Agreements are hereby amended to delete any references to an Escrow Agent, Escrow Account, Escrow Fund or Escrow Agreement. Sections 11.4 and 11.5 of the SPC Agreement are hereby deleted in their entirety and replaced by Exhibit A-1 attached to this letter agreement.

Subsections (d) and (e) of Section 10.1 are deleted, and subsection (b) is modified by substituting "January 31" for "January 1".

The first sentence of Section 9.1.A in each Agreement is hereby deleted. Purchaser accepts that time is of the essence, and that part of the consideration for SPC in accepting a reduced Aggregate Purchase Price is the expectation of a prompt Closing. Each of the parties agrees in good faith to use all reasonable commercial efforts to close within the dates indicated, and the parties will agree on the exact date as soon as practicable. 9. Consents and Approvals. With respect to the conditions precedent to Closing set forth in Section 5.6, Purchaser hereby waives certain matters as follows, and the Company, PPI and Purchaser hereby agree as follows: (a) Farragut Street/Colonial Pipeline, Inc.

Purchaser assumes responsibility for obtaining such permits, consents or any other authorizations required from NPS to operate the M Street Terminal and the PPI Pipeline. From and after the Closing Date Purchaser shall assume all liability arising from and after the Closing Date from the failure to have such permits, consents or authorizations.

(e) Florida Power & Light ("FP&L"): Purchaser acknowledges that FP&L has agreed to exercise its one year renewal option on the same terms and conditions set forth in its existing agreement with SPC. A copy of FP&L's letter dated November 27, 1995 exercising its option is attached as Exhibit C. (f) Florida Submerged Land Issues: Purchaser agrees to assume responsibility for the completion of all matters related to the Florida submerged lands disclosed in the letter, 6 Edward D.

(including the payment of any fees or expenses (including attorneys' fees) incurred on or after the Closing Date by Purchaser for the resolution of such matters). If as a result of Purchaser obtaining leases for a portion of the Phillips Dock and for submerged land where the tankers berth rent is required by the State of Florida for any period before the Closing Date, SPC agrees to pay such retroactive rent, provided that Purchaser has consulted with SPC in negotiating said matter and provided SPC with the opportunity to be present at the negotiations. (g) Other Consents: (i) Purchaser waives the requirement to obtain consents from Mr. and Mrs. James C. Greenwell, Stephen and Cindy Gass and Mary G. Norris, collectively known as the Greenwells, to the assignment of the relevant Right of Way Agreements affecting the PEPCO Pipeline.
