Item 5.           Other Events and Regulation FD Disclosure
-------           -----------------------------------------

                  On June 21, 2002, ONEOK, Inc. (the "Company") entered into a
                  90-day extension of its $850 million revolving credit facility
                  with a syndicate of 12 banks, led by Bank of America, N.A. The
                  amended credit facility becomes effective June 27, 2002. The
                  credit facility, which was originally scheduled to expire on
                  June 27, 2002, has been extended to the earlier of (1)
                  September 30, 2002, (2) if the Company elects to do so, the
                  date on which the Company purchases any shares of the
                  Company's common or preferred stock owned by Westar Energy
                  Inc., formerly Western Resources, and its subsidiary, Westar
                  Industries, Inc., (collectively, "Western"), or (3) the date
                  the Company enters into a new loan or credit agreement
                  providing for extensions of credit to the Company.

                  The credit facility, as extended, continues to provide that
                  loan proceeds may be used by the Company to provide liquidity
                  for commercial paper, working capital, capital expenditures,
                  acquisitions, mergers and other general corporate purposes.
                  The credit facility, as extended, provides that no portion of
                  loan proceeds will be used to repurchase shares of capital
                  stock of the Company. If the Company elects to purchase the
                  shares of the Company's common or preferred stock from Western
                  and regulatory approval is required for such purchase, the
                  credit facility may be extended to November 29, 2002 with
                  approval of the lenders.

                  As previously reported, on May 30, 2002 Western delivered a
                  sale notice (the "Sale Notice") to the Company giving notice
                  of Western's intent to sell 4,714,434 shares of the Company's
                  common stock (the "Common Stock") and 19,946,448 shares of the
                  Company's Series A Convertible Preferred Stock (the "Preferred
                  Stock") representing all of the Common Stock and Preferred
                  Stock of the Company beneficially owned by Western.

                  Pursuant to the terms of the Shareholder Agreement between the
                  Company and Western dated November 26, 1997, (the "Shareholder
                  Agreement"), the delivery of the Sale Notice to the Company
                  gives the Company or its designee the option to purchase, for
                  a period of 90 days after the date of the Sale Notice, all,
                  but not less than all, of the Common Stock and Preferred Stock
                  at a price equal to 98.5% of the average of the closing prices
                  of the Company's Common Stock during the 20 trading days prior
                  to the date of the Sale Notice. This sale period can be
                  extended 30 days after any necessary regulatory approvals, but
                  cannot exceed 180 days after the date of the Sale Notice.

                  The Company believes that the extension of its credit facility
                  provides the Company with the flexibility to consider its
                  options regarding Western's proposed sale of its equity stake
                  in the Company. The Company is carefully reviewing its options
                  under the Shareholder Agreement and will take such action as
                  the Company believes is in the best interest of ONEOK
                  shareholders.
