Item 5.    Other Events and Regulation FD Disclosure

           On August 28, 2002, Moody's Investor Services announced that it
           downgraded its ratings of ONEOK, Inc. ("the Company') with a negative
           outlook. The Company's ratings were changed as follows:

                 ONEOK, Inc. - senior unsecured from A2 to Baa1; shelf
                 registration from (P)A2/(P)A3 to (P)Baa1/(P)Baa2; commercial
                 paper from Prime-1 to Prime-2;
                 ONEOK Capital Trust I - preferred shelf (P)A3 to (P)Baa2;
                 ONEOK Capital Trust II - preferred shelf (P)A3 to (P)Baa2.

           In response to Moody's decision to change the Company's ratings, the
           Company has pointed to its strong balance sheet and asset base and
           its continued strategic focus. Although the change in the Company's
           rating may result in an increase in the Company's cost to borrow
           funds, the Company believes that this change will not have a material
           adverse effect on its financial position, cash flows and results of
           operations.
