*INTRODUCTORY NOTE

The Williams Companies, Inc. owns all of the membership interests in Williams
Energy Services, LLC, a Delaware limited liability company ("WES"), and all of
the common stock of Williams Natural Gas Liquids, Inc., a Delaware corporation
("WNGL"), and as such, may have been deemed to beneficially own the Common Units
owned by those two entities. On June 17, 2003, WES and WNGL sold all of their
securities issued by Williams Energy Partners L.P., a Delaware limited
partnership (the "Issuer"), to a new entity formed jointly by private equity
firms Madison Dearborn Partners, LLC and Carlyle/Riverstone Global Energy and
Power Fund II, L.P. This Amendment No. 1 to Schedule 13D (this "Amendment No.
1") is being filed by WES, WNGL, and The Williams Companies, Inc. (collectively,
the "Reporting Persons"), who comprise a group under Rule 13d-5(b) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"). This Amendment
No. 1 amends the statement on Schedule 13D filed by the Reporting Persons on
February 19, 2001 with respect to Common Units representing limited partnership
interests of the Issuer, which has its principal executive offices at P.O. Box
22186, Tulsa, Oklahoma. In addition to the Items specified below, each other
Item of the Statement to which the information set forth below is relevant is
amended hereby. This Amendment No. 1 has been filed to report that the Reporting
Persons no longer hold any Common Units of the Issuer and each Reporting Person
has therefore ceased to be the owner of more than 5 percent of any class of
securities.

ITEM 2. IDENTITY AND BACKGROUND.

WES and WNGL sold all of their Common Units of the Issuer that they beneficially
own pursuant to the transaction described in Item 5. Accordingly, all Reporting
Persons named in this Schedule 13D are no longer reporting persons.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

Not applicable.

ITEM 4. PURPOSE OF THE TRANSACTION.

Not applicable.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

         (a)      Number of Common Units or other securities of the Issuer
                  beneficially owned by the Reporting Persons: -0-

                  Percentage of class of Common Units beneficially owned by the
                  Reporting Persons: 0.0%

         (b)      Number of Common Units as to which, with respect to the
                  Reporting Persons, there is sole power to vote or direct the
                  vote, shared power to vote or to direct the vote, sole power
                  to dispose or to direct the disposition, or shared power to
                  dispose or direct the disposition: -0-

         (c)      On June 17, 2003, WES and WNGL sold all of their securities
                  issued by the Issuer to WEG Acquisitions, L.P. ("Buyer"), a
                  new entity formed jointly by private equity firms Madison
                  Dearborn Partners, LLC and Carlyle/Riverstone Global Energy
                  and Power Fund II, L.P. The securities sold in that
                  transaction included: (1) 757,193 Common Units and 4,589,193
                  Subordinated Units owned of record by WES; (2) 322,501 Common
                  Units and 1,090,501 Subordinated Units owned of record by
                  WNGL; and (3) 7,830,924 Class B Common Units owned of record
                  by Williams GP LLC, an indirect wholly owned subsidiary of The
                  Williams Companies, Inc. The consideration for the sale of
                  such units was $509,868,000 together with the rights to
                  potentially receive the additional amounts described in
                  Subsection (d) of this Item 5. The transaction was effected
                  pursuant to the Purchase Agreement, dated April 18, 2003, by
                  and among, WES, WNGL, Williams GP LLC, and Buyer (filed as
                  Exhibit 99.1 to the report on Form 8-K of The Williams
                  Companies, Inc., dated April 18, 2003),





                  which is incorporated herein by reference, as amended by
                  Amendment No. 1 to the Purchase Agreement filed herewith (as
                  amended, the "Purchase Agreement").

         (d)      Subject to the limitations described therein and as more
                  particularly described therein, the Purchase Agreement
                  provides that WES, WNGL, and Williams GP LLC will be entitled
                  to (i) a payment from the Buyer if it sells Common Units or
                  Subordinated Units or such units are redeemed by the Issuer at
                  net prices exceeding $37.50 per unit and (ii) a payment from
                  the Buyer of an amount based on a portion of the Issuer
                  distributions for the second quarter of 2003 with respect to
                  the units sold by the Reporting Persons and Williams GP LLC.

         (e)      On June 17, 2003, the Reporting Persons ceased to be the
                  beneficial owners of more than five percent of the Common
                  Units.
