--------

1    As described herein, in the merger of Barrett Resources Corporation
     with and into Resources Acquisition Corp., with Resources Acquisition
     Corp. surviving, each issued and outstanding share of Barrett
     Resources Corporation was cancelled.

2    Based on the 33,479,127 shares issued and outstanding on August 2, 2001.



         The Williams Companies, Inc., a Delaware corporation ("Williams"),
and Resources Acquisition Corp., a Delaware corporation and a wholly-owned
subsidiary of Williams ("Purchaser" and together with Williams, the
"Reporting Persons"), hereby file this Amendment No. 2 (this "Amendment No.
2") to amend and supplement the Statement on Schedule 13D originally filed
on June 15, 2001 by the Reporting Persons (the "Schedule 13D") with respect
to the shares ("Shares") of common stock, par value $.01 per Share
(including the associated preferred stock purchase rights), of Barrett
Resources Corporation, a Delaware corporation ("Barrett Resources"). The
Schedule 13D was originally filed as the Final Amendment to the Schedule TO
of the Reporting Persons with respect to the Shares acquired by Purchaser
in a tender offer completed on June 11, 2001. Capitalized terms used but
not described herein shall have the meanings ascribed thereto in the
Schedule 13D. The Schedule 13D is hereby amended and supplemented by this
Amendment No. 2, which constitutes the Final Amendment to the Schedule 13D.


ITEM 4.  PURPOSE OF TRANSACTION


ITEM 5.  INTERESTS IN SECURITIES OF THE ISSUER

         The response to Item 4 and Items 5(a) and 5(b) of the Schedule 13D
is hereby amended and supplemented to add the following:

         On August 2, 2001, pursuant to the Agreement and Plan of Merger,
dated as of May 7, 2001, by and among Williams, Purchaser and Barrett
Resources, Barrett Resources merged with and into Purchaser with Purchaser
as the surviving corporation continuing as a wholly owned subsidiary of
Williams. As of the effective time of the merger (the "Effective Time"),
all issued and outstanding Shares (other than Shares owned by Williams and
Purchaser) were converted into the right to receive 1.767 shares of
Williams common stock (together with the associated preferred stock
purchase rights). The Reporting Persons, the holders of 16,730,502 issued
and outstanding Shares prior to the Effective Time, thus became the owners
of 100% of the issued and outstanding Shares. As a result of the merger,
the Shares have become eligible for termination of registration pursuant
to Section 12(g)(4) of the Securities Exchange Act of 1934 and will be
delisted from the New York Stock Exchange. The joint press release issued
by Williams and Barrett Resources on August 2, 2001 announcing the
completion of the merger is filed as Exhibit 99.2 to this Amendment No.2
and is incorporated herein by reference.
