               STATEMENT UNDER OATH OF PRINCIPAL FINANCIAL OFFICER
                        REGARDING FACTS AND CIRCUMSTANCES
                        RELATING TO EXCHANGE ACT FILINGS

I, John D. Chandler, Chief Financial Officer and principal financial officer of
Williams GP LLC, the General Partner of Williams Energy Partners L.P., state and
attest that:

         (1)      To the best of my knowledge, based upon a review of the
                  covered reports of Williams Energy Partners L.P., and, except
                  as corrected or supplemented in a subsequent covered report:

                  o        no covered report contained an untrue statement of a
                           material fact as of the end of the period covered by
                           such report (or in the case of a report on Form 8-K
                           or definitive proxy materials, as of the date on
                           which it was filed); and

                  o        no covered report omitted to state a material fact
                           necessary to make the statements in the covered
                           report, in light of the circumstances under which
                           they were made, not misleading as of the end of the
                           period covered by such report (or in the case of a
                           report on Form 8-K or definitive proxy materials, as
                           of the date on which it was filed).

         (2)      I have reviewed the contents of this statement with the Audit
                  Committee of Williams GP LLC, the General Partner of Williams
                  Energy Partners L.P.

         (3)      In this statement under oath, each of the following, if filed
                  on or before the date of this statement, is a `covered
                  report':

                  o        Annual Report on Form 10-K for the fiscal year ended
                           December 31, 2001 filed with the Commission of
                           Williams Energy Partners L.P.;

                  o        all reports on Form 10-Q, all reports on Form 8-K and
                           all definitive proxy materials of Williams Energy
                           Partners L.P. filed with the Commission subsequent to
                           the filing of the Form 10-K identified above; and

                  o        any amendments to any of the foregoing.
