from Sellers the fuel distribution business of Northland Fuel and its
subsidiaries; and

         WHEREAS, Purchaser and Sellers have agreed, pursuant to Section 13.9 of
the Purchase Agreement, to amend the Purchase Agreement on the terms provided

         NOW, THEREFORE, in consideration of the foregoing and other good and
valuable consideration, the receipt of which is hereby acknowledged, the Parties
agree as follows:

         Section 1. Amendment. The Purchase Agreement is hereby amended as
follows:

         (a) Section 2.2 is hereby amended by deleting subsection (b)(ii) of
such Section in its entirety and inserting in lieu thereof the following:

                  "(ii) Purchaser shall prepare and deliver to Sellers within
         ninety (90) days after the Closing Date (A) calculations of SOG's
         Adjusted NWC (the "Final SOG Adjusted NWC") and YFC's Adjusted NWC (the
         "Final YFC Adjusted NWC"), in each case as of the Closing, and (B) a
         reconciliation of the Preliminary SOG Adjusted NWC and Preliminary YFC
         Adjusted NWC calculations to the Final SOG Adjusted NWC and Final
<PAGE>

         YFC Adjusted NWC calculations, together with all supporting
         documentation and computations (collectively, the "Reconciliation").
         The Parties hereby acknowledge and agree that liabilities for "Income
         Tax Payable" (as identified as a separate line item in Schedule 2.2)
         cannot be calculated by Purchaser, and therefore Purchaser's
         calculations of Final SOG Adjusted NWC and Final YFC Adjusted NWC
         delivered to Sellers shall each include such liabilities as were
         originally provided by Sellers pursuant to Section 2.2(b)(i). Purchaser
         shall promptly make available to Sellers all personnel, books, records
         and documents reasonably requested by Sellers for purposes of their
         review of Purchaser's calculation of the Final YFC Adjusted NWC and the
         Final SOG Adjusted NWC."

         (b) Section 2.2 is hereby amended by deleting subsection (b)(iii) of
such Section in its entirety and inserting in lieu thereof the following:

                  "(iii) No later than January 13, 2005, Sellers shall deliver
         to Purchaser a written report setting forth in reasonable detail both
         its calculation of "Income Tax Payable" liabilities and its proposed
         adjustments, taking into account such "Income Tax Payable" liabilities,
         to the Final SOG Adjusted NWC or the Final YFC Adjusted NWC (the
         "Adjustment Report")."

         Section 2. Effective Date; No Implied Amendments. Each of the Parties
agrees that the amendment to the Purchase Agreement contained herein shall be
effective upon execution of this Amendment by each Party. Except as specifically
amended by this Amendment, the Purchase Agreement shall remain in full force and
effect in accordance with its respective terms and is hereby ratified and
confirmed. This Amendment shall not be deemed to constitute a waiver of, or
consent to, or a modification or amendment of, any other provision of the
Purchase Agreement except as expressly provided herein or to prejudice any other
right or rights which any Party may now have or may have in the future under or
in connection with the Purchase Agreement. This Amendment shall not constitute
an agreement or obligation of any Party to consent to, waive, modify or amend
any other term, condition, subsection or section of the Purchase Agreement.

         Section 3. Benefit of the Agreement. This Amendment shall be binding
upon and inure to the benefit of the Parties and their respective successors and
permitted assigns. This Amendment shall not be construed so as to confer any
right, remedy or benefit upon any Person, other than the Parties and their
respective successors and permitted assigns.

         Section 4. Headings. The headings used in this Amendment are for
convenience of reference only and shall not be deemed to limit, characterize or
in any way affect the interpretation of any provision of this Amendment.

         Section 5. GOVERNING LAW. THIS AMENDMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK WITHOUT
REGARD TO ITS CONFLICT OF LAW PRINCIPLES.

         Section 6. Counterparts. This Amendment may be executed in
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         Section 7. References to Agreement. On and after the date hereof, each
reference in the Purchase Agreement to "this Agreement," "hereunder," "hereof"
or words of like import referring to the Purchase Agreement shall mean the
