Item 1.  Security and Issuer.


     This statement on Schedule 13D (the "Statement") is filed by Westar Energy,
Inc. (f/k/a Western Resources, Inc.) ("Westar Energy") and Westar Industries,
Inc. (f/k/a Westar Capital, Inc.), a Delaware corporation and a wholly owned
subsidiary of Westar Energy ("Westar Industries" and, together with Westar
Energy, the "Reporting Persons"), and relates to the Common Stock, par value
$0.01 per share (the "Common Stock"), of ONEOK, Inc., an Oklahoma corporation
(the "Issuer") which Common Stock is held by Westar. This Statement supplements
and amends the statement on Schedule 13D originally filed by Western with the
Commission on December 5, 1997, as amended by Amendment No. 1, filed with the
Commission on November 29, 1999, Amendment No. 2, filed with the Commission on
January 27, 2000, Amendment No. 3, filed with the Commission on March 8, 2000,
Amendment No. 4 filed with the Commission on April 8, 2002, Amendment No. 5
filed with the Commission on April 26, 2002, Amendment No. 6 filed with the
Commission on May 23, 2002 and Amendment No. 7 filed with the Commission on June
3, 2002 (as amended, the "Schedule 13D").

     The address of the principal executive offices of the Issuer is: ONEOK,
Inc., 100 West Fifth Street, Tulsa, Oklahoma 74103.

Item 4.  Purpose of the Transaction.


     The last paragraph of Item 4 is deleted and following disclosure is in lieu
     thereof (capitalized terms not otherwise defined herein are used as defined
     in the Shareholder Agreement filed as Exhibit 3 to this Schedule 13D):


                                  Page 6 of 8



     On May 30, 2002, notice was given pursuant to Section 3.4(b) of the
     Shareholder Agreement with ONEOK, Inc. ("ONEOK") of the intention of Westar
     Industries, Inc. ("Westar Industries") to sell all of the common stock and
     preferred stock of ONEOK owned by Westar Industries to a third person. As a
     result of this notice having been given, ONEOK or its designee had the
     right to purchase the common stock and preferred stock at a cash sales
     price of $21.77 per share for a period ending on the later of 90 days after
     May 30, 2002 (August 28, 2002) and 30 days from the date of receipt of all
     necessary regulatory approvals, but in no event later than 180 days after
     May 30, 2002. On August 22, 2002, ONEOK advised Westar Industries that it
     was not going to exercise its right to purchase the common stock and
     preferred stock on August 28, 2002.


     Therefore, on August 29, 2002, Westar Industries announced that it
     currently plans to sell outright, or sell an option to purchase, all or a
     portion of the ONEOK stock it owns in privately negotiated transactions, or
     sales into the public market. Under the Shareholder Agreement, Westar
     Industries is now free to pursue a sale of the stock and is free of certain
     restrictions (including percentage limitations on sales) contained in that
     agreement. Under the Shareholder Agreement, ONEOK must also take all
     commercially reasonable steps to assist Westar Industries in securing such
     regulatory approvals as may be necessary to allow a sale of the stock
     provided such approvals would not reasonably be expected to have a material
     adverse effect on ONEOK. The terms of the Shareholder Agreement allow
     Westar Industries until September 30, 2003 to complete a sale of the stock.


     The Reporting Persons have engaged JPMorgan to advise them with respect to
     this matter.
