Item 5.02               Departure of Directors or Certain Officers; Election of Directors;
                        Appointment of Certain Officers; Compensatory Arrangements of Certain
                        Officers

                        On May 4, 2022, John W. Gibson, 69, informed ONEOK, Inc. (the "Company")
                        of his decision to retire as a member of the Board of Directors (the
                        "Board") and as chairman of the Board, effectively immediately, after
                        having served on the Board since 2006. Following Mr. Gibson's retirement
                        from the Board, the size of the Board was reduced to ten (10).

                        Mr. Gibson's retirement was not due to any disagreement with the Company,
                        including on any matter relating to its operations, policies or practices.

                        ONEOK, Inc. appreciates Mr. Gibson's service to the Board.

                        On May 5, 2022, Julie H. Edwards, 63, was appointed by the Board to
                        succeed Mr. Gibson as Board chair. Ms. Edwards, of Houston, Texas, has
                        been a Company director since 2007 and most recently served as the
                        Company's Lead Independent Director and Corporate Governance Committee
                        chair.
