is set forth in Exhibit 1.2 and is incorporated by reference herein. During the

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 7 to this Schedule 13D):

     On January 9, 2003, Westar Energy announced that it and Westar Industries,
Inc. have entered into an agreement with ONEOK, Inc. to sell ONEOK a portion of
the shares of ONEOK Series A Convertible Preferred Stock held by Westar
Industries at the prevailing market price, less transaction costs, and to
exchange Westar Industries' remaining shares of Series A Convertible Preferred
Stock for new shares of ONEOK $0.925 Series D Non-Cumulative Convertible
Preferred Stock. ONEOK will use half of the net proceeds up to $250 million from
planned financing transactions to pay Westar Industries for the Series A
Convertible Preferred Stock. The effectiveness of the sale and related
transactions is subject to approval by the Kansas Corporation Commission (KCC)
and other conditions, including ONEOK's receipt of the proceeds from its planned
financing transactions. In connection with this agreement, certain agreements
among Westar Energy, Westar Industries and ONEOK were amended subject to the
approval of the KCC.

     ONEOK has agreed to file a shelf registration statement, following
completion of the sale and the exchange, to register for resale to the public
all the Series D Convertible Preferred shares held by Westar Industries and 4.7
million shares of ONEOK common currently held by Westar Industries. The timing
of sales of the stock held by Westar Industries will be governed by a new
Registration Rights Agreement entered into among Westar Energy, Westar
Industries and ONEOK and to market and other conditions.

     The Series D Convertible Preferred Stock will have substantially the same
terms as the Series A Convertible Preferred Stock, except that:

     o    The Series D Convertible Preferred Stock will have a fixed quarterly
          cash dividend of 23.125 cents per share, as declared by ONEOK's board
          of directors;

     o    The Series D Convertible Preferred Stock will be redeemable by ONEOK
          at any time after August 1, 2006 in the event that the closing price
          of ONEOK common stock exceeds $25 for 30 consecutive trading days
          after such date; the per share redemption price will be $20;

     o    Each share of Series D Convertible Preferred Stock will be convertible
          into one share of ONEOK common stock, subject to adjustment for stock
          splits, stock dividends, reverse stock splits or any transaction with
          comparable effects; and

                                  Page 6 of 11


     o    Westar Industries may not convert any shares of Series D convertible
          Preferred Stock held by it unless the annual per share dividend for
          the ONEOK common stock for the previous year is greater than 92.5
          cents per share and such conversion would not subject Westar Energy,
          Westar Industries nor ONEOK to the Public Utility Holding Company Act
          of 1935.

     Westar Energy, Westar Industries and ONEOK have also agreed to amend the
terms of their existing Shareholder Agreement and Registration Rights Agreement.
The new agreements will not be effective until the sale and the exchange are
completed. Under the new agreements:

     o    Westar Industries will be prohibited from acquiring any additional
          securities of ONEOK.

     o    Westar Industries may make private sales of shares as long as each
          sale involves less than five percent of ONEOK's outstanding common
          shares (assuming conversion of the Series D Convertible Preferred
          Stock to be sold) and is made to an owner of less than five percent of
          ONEOK's outstanding common shares. Westar Industries may make public
          sales in any broad underwritten offering under the shelf registration
          statement.

     o    Westar Industries will have the right to designate one ONEOK board
          member.

     o    Westar Industries will not be obligated to sell into stock repurchases
          by ONEOK.

     o    The new Shareholder Agreement will terminate if Westar Energy's or any
          affiliate's beneficial ownership falls below 10 percent of ONEOK's
          outstanding common shares (assuming conversion of the Series D
          Convertible Preferred into ONEOK common stock).

     o    The top-up rights, dilutive issuance rights and buy/sell option
          provided for in the previous Shareholder Agreement are eliminated in
          the new agreement.
