                            CERTIFICATE OF CORRECTION

      This Certificate of Correction is filed to correct a certain error in the
Certificate of Formation of ACBL LIQUID SALES LLC filed in the Office of the
Secretary of State of Delaware on the fifth day of July, 2000.

      ACBL Liquid Sales LLC, a limited liability company organized and existing
under and by virtue of the Revised Limited Liability Company Act of the State of
Delaware,

      DOES HEREBY CERTIFY:

      1.    The name of the limited liability company is ACBL Liquid Sales LLC.

      2.    That a Certificate of Formation was filed by the Secretary of State
            of Delaware on July 5, 2000 and that said Certificate requires
            correction as permitted by Section 18.211 of the Revised Limited
            Liability Company Act of the State of Delaware.

      3.    The inaccuracy or defect of said Certificate to be corrected is as
            follows:

            The first paragraph states that James J. Farley is the authorized
            person to form the company, when, in fact, the Certificate of
            Formation is executed by Paul S. Besson as the Authorized Person.

      4.    The corrected portion of the Certificate is set forth as follows:

            "This Certificate of Formation of ACBL Liquid Sales LLC (the "LLC"),
            dated as of June 29, 2000, is being duly executed and filed by Paul
            S. Besson, as an authorized person, to form a limited liability
            company under the Delaware Limited Liability Company Act (6 Del.
            Section 18-101 et seq.)."

      IN WITNESS WHEREOF, the undersigned has executed this certificate this
17th day of July 2000.
