Kyle to Remain Chairman of ONEOK, Inc.; Board Also Approves Actions Related to Election of Directors

October 18, 2007

TULSA, Okla., Oct 18, 2007 /PRNewswire-FirstCall via COMTEX News Network/ -- The board of directors of ONEOK, Inc. (NYSE: OKE) today elected David Kyle as non-executive chairman of ONEOK, Inc., effective Jan. 1, 2008, when he will retire as a full-time employee. Kyle is currently executive chairman of ONEOK. From August 2000 until Jan. 1, 2007, he was chairman, president and chief executive officer of the company.

In other actions, the board approved submitting to shareholders an amendment to the company's certificate of incorporation to provide for the annual election of directors. The amendment must be approved by 80 percent of the company's outstanding shares at its annual meeting to be held in the spring of 2008. Currently, the ONEOK board of directors is separated into three classes of directors, with each director in a class standing for re-election every three years.

The board also amended the company's bylaws to allow for election of directors in uncontested elections by a majority vote of those shareholders voting. The current practice of electing directors by a plurality will continue to apply for contested elections. This change does not require approval of shareholders.

"These changes in our corporate governance are consistent with current best practices and reinforce our commitment to shareholder accountability," said ONEOK Chairman David Kyle. "We believe over the long term, good governance enhances shareholder value."

At its January 2008 board meeting, ONEOK expects to schedule its annual meeting of shareholders and establish a record date for the meeting.
