TYPE OF REPORTING PERSON CO -------- 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).
