Effective September 6, 2007, the Board of Directors (the “Board”) of Cheniere Energy, Inc. (the “Company”) approved Amendment No. 2 (the “Amendment”) to the Company’s Amended and Restated By-Laws, as amended (the “By-Laws”). The Amendment amends Article V of the By-Laws to permit both certificated and uncertificated shares of the Company’s common stock in order to satisfy the new requirements of Rule 135 of the American Stock Exchange Company Guide. Prior to the Amendment, the By-Laws required that all such shares be certificated. In addition, the Amendment deletes Section 4.15 of the By-Laws, which provided that compensation of the officers of the Company was to be fixed by the Board. The compensation of the executive officers will continue to be fixed by the Compensation Committee of the Board pursuant to the Compensation Committee’s Charter and in compliance with the rules and regulations of the American Stock Exchange.

The foregoing description of the Amendment is qualified in its entirety by the terms of the Amendment, which is filed as Exhibit 3.1 to, and incorporated by reference in, this Current Report on Form 8-K.
