Item 5.    Other Events.
- -------    -------------

        On May 15, 2001, the Company issued a press release announcing a
        revision in its computation of earnings per share for common stock (EPS)
        to conform to a recent announcement of the Financial Accounting
        Standards Board Staff codified in Emerging Issues Task Force Topic D-95
        (Topic D-95).  The interpretation of Statement of Financial Accounting
        Standards No. 128 "Earnings per Share" (SFAS No. 128) requires a
        revision to the method of earnings per share computation for convertible
        and participating securities such as ONEOK's Series A Convertible
        Preferred Stock.

        EPS included in the Company's Form 10-Q for the three months ended March
        31, 2001 and 2000, filed with the Securities and Exchange Commission
        (SEC) on May 15, 2001, were calculated in accordance with Topic D-95.
        Reference should be made to our March 31, 2001 Form 10-Q for additional
        information on the specific changes to our EPS computations to comply
        with Topic D-95.  The 2000 Annual Report on Form 10-K (Form 10-K), filed
        with the SEC on March 26, 2001, is not required to be amended for the
        application of Topic D-95.  Topic D-95 is an interpretation of SFAS No.
        128 that is applied upon the issuance of Topic D-95, and only requires
        EPS computations and disclosures for prior periods to be amended for the
        interpretation included in Topic D-95 as these periods are presented as
        comparative periods in future filings.

        On May 17, 2001, the Company's shareholders approved a two-for-one split
        of the Company's common stock to be effected by the Company  issuing one
        additional share of common stock for each outstanding share of common
        stock to holders of record on May 23, 2001, with distribution of the
        split shares on June 11, 2001.  This Form 8-K presents in the summary
        table at Exhibit 99.a.1 the previously reported EPS, EPS to conform with
        Topic D-95, and EPS giving retroactive effect to the two-for-one stock
        split and the application of Topic D-95 for the periods included in the
        Form 10-K and other selected periods.  Exhibits 99.a.2 through 99.a.16
        include the revised calculation and disclosures of EPS to conform with
        Topic D-95 and give retroactive effect to the May 2001 two-for-one stock
        split.  These amended EPS computations and disclosures will be included
        in applicable future filings as these prior periods are required to be
        presented.
