KINDER MORGAN, INC. SHAREHOLDERS APPROVE MERGER AGREEMENT TO SELL COMPANY TO INVESTOR GROUP

HOUSTON, Dec. 19, 2006 – Kinder Morgan, Inc. (NYSE: KMI) today announced that stockholders have voted to approve the proposed merger agreement providing for the acquisition of KMI by investors including Chairman and CEO Richard D. Kinder, other senior members of KMI management, co-founder Bill Morgan, current board members Fayez Sarofim and Mike Morgan, and affiliates of Goldman Sachs Capital Partners, American International Group, Inc., The Carlyle Group and Riverstone Holdings LLC.  

Approximately 100 million shares of common stock were voted at the special meeting, representing about 75 percent of KMI’s total outstanding shares.  Of those shares voting, approximately 97 million, or about 97 percent, voted in favor of the adoption of the merger agreement, representing approximately 73 percent of KMI’s total shares.  Approval by more than two-thirds of KMI’s total number of shares was required.  

Under the terms of the merger agreement, promptly following the closing of the merger, KMI stockholders (other than Knight Holdco LLC, Knight Acquisition Co., subsidiaries of KMI, stockholders who have perfected their appraisal rights under Kansas law and stockholders defined in the KMI proxy statement as Rollover Investors) will receive $107.50 in cash, without interest, for each share of KMI common stock held.  This represents a premium of approximately 27 percent over $84.41, the closing price of KMI stock on Friday, May 26, the last trading day before the investor group made its proposal to take the company private.  

The transaction is anticipated to close in the first quarter of 2007, subject to receipt of regulatory approvals and the satisfaction of other customary closing conditions.  The transaction is valued at approximately $22 billion and includes the assumption of about $7 billion of debt.
