INTRODUCTORY NOTE On August 30, 2000, The Williams Companies, Inc., a Delaware corporation ("Williams"), filed a Schedule 13D/A reporting that it had acquired shared voting power with respect to 3,568,791 units of beneficial interest (the "Subject Units") in the Trust pursuant to a Nominee and Voting Rights Agreement, dated August 11, 2000, entered into by Williams and Quatro Finale IV, LLC ("Quatro") (as amended by Amendment No. 1 dated November 8, 2001, the "Nominee and Voting Rights Agreement"). The Nominee and Voting Rights Agreement was entered into in connection with the sale of the Subject Units to Quatro pursuant to the Purchase and Sale Agreement dated August 11, 2000 between Williams and Quatro (as amended by Amendment No. 1 dated September 26, 2001, the "Purchase Agreement"). Also pursuant to the Purchase Agreement, Williams acquired a call option (the "Call Option"), to purchase, in one or more lots of 10,000 units, the Subject Units (as reported on Form 4 filed September 26, 2000) and Quatro acquired an option to require Williams to purchase the Subject Units (the "Put Option"). In December of 2001 and in January of 2002, Williams, through several exercises of its Call Option, purchased an aggregate of 260,000 of the Subject Units from Quatro (the "Trust Units"), changing only the form by which it beneficially owned a portion of the Subject Units from derivative securities to underlying securities. During December of 2001 and January of 2002 Williams also sold many of the Trust Units it had acquired pursuant to its Call Option in the public market under an effective registration statement on Form S-3 filed September 28, 2001. On January 4, 2002, Williams filed a Schedule 13D/A reporting that it had shared voting power with respect to 3,308,791 Subject Units and sole voting and dispositive power of 85,600 Trust Units. On April 22, 2002, Williams filed a Schedule 13D/A reporting that it had shared voting power with respect to 3,108,791 Subject Units and sole voting and dispositive power of 143,400 Trust Units. On September 4, 2002, Williams filed a Schedule 13D/A reporting that it had shared voting power with respect to 3,008,791 Subject Units and sole voting and dispositive power of 60,000 Trust Units. On October 2, 2002, Williams filed a Schedule 13D/A reporting that it had shared voting power with respect to 2,858,791 Subject Units and sole voting and dispositive power of 108,800 Trust Units. The purpose of this Amendment No. 6 on Schedule 13D/A is to reflect the fact that Williams owns beneficial interest in the remaining Subject Units in the form of derivative securities and the fact that Williams has sold underlying Trust Units that it acquired pursuant to exercises of its Call Option. ITEM 1. SECURITY AND ISSUER. This Amendment No. 6 on Schedule 13D/A (this "Amendment No. 6") relates to the Trust Units and the Subject Units and is being filed by Williams. This Amendment No. 6 amends Items 3 and 5 of Amendment No. 5 on Schedule 13D/A filed on October 2, 2002. ITEM 2. IDENTITY AND BACKGROUND. No change. 3 ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. Williams acquired beneficial ownership of the Subject Units on August 11, 2000 in the form of a Call Option granted to it by Quatro pursuant to the Purchase Agreement. Williams was granted the Call Option by Quatro in exchange for the Put Option to Quatro under the Purchase Agreement. The Call Option may be exercised at a stated strike price, which is subject to certain adjustments (including with respect to certain distributions, tax credits, adjustments thereto and accrued interest). Williams, through a series of exercises of its Call Option, acquired an aggregate of 150,000 Trust Units from October 1, 2002 through November 15, 2002. Williams funded the purchase of the Trust Units through general corporate funds. From October 1, 2002 to November 15, 2002, Williams sold an aggregate of 108,800 Trust Units in the public market through ordinary broker-dealer transactions pursuant to an effective registration statement filed on September 28, 2001 at the market price on the date of sale. The weighted average price received by Williams for the sale of the Trust Units was $8.8669. ITEM 4. PURPOSE OF TRANSACTION No change. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER AS OF NOVEMBER 15, 2002. (a) There were 9,700,000 units of the Trust outstanding as of March 1, 2002. Williams is deemed to be the beneficial owner of 2,858,791 units, of which 2,708,791 units are owned in the form of the Call Option and 150,000 of which are owned in the form of common units. The units constitute 29.47% of the issued and outstanding common units. (b) Sole power to vote or to direct the vote: Shared power to vote or to direct the vote: Sole power to dispose or to direct the disposition: Shared power to dispose or to direct the disposition: (c) There have been the reportable transactions with respect to the Trust Units within the last 60 days by Williams, which have been reported on Form 4. (d) Williams has the right to receive distributions from, and proceeds from the sale of, the Trust Units reported in Item 9 of the cover page. To the extent that Williams has not exercised its Call Option, Williams does not have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, any of the Subject Units or any other units of the Trust. (e) Not applicable. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER. No change. ITEM 7. MATERIAL TO BE FILED AS EXHIBITS None. 4 SIGNATURE After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
