Modification of Issuer Call Spread Options

As previously disclosed, in connection with its issuance of $325 million of 2.25% Convertible Senior Notes due 2012, Cheniere Energy, Inc. (the “Company”) entered into an issuer call spread (the “Issuer Call Spread Options”) with Credit Suisse First Boston International, now known as Credit Suisse International (“Credit Suisse”), pursuant to a Confirmation, dated July 22, 2005 (the “Confirmation”), and a related Notice of Adjustment, dated July 26, 2005 (the “Notice of Adjustment” and, together with the Confirmation, the “Confirmation Documents”).

On May 31, 2007, the Company delivered a written notice (the “Notice of Commitment”) notifying Credit Suisse of the Company’s irrevocable commitment to exercise, on one or more occasions on or before July 23, 2007, all of the call options granted by Credit Suisse to the Company pursuant to the Confirmation Documents and electing physical settlement of its call option (i.e., purchase and sale of shares of Company common stock rather than settlement for cash). As a result, the Company’s call options have been changed so that the Company is now irrevocably committed to purchase 9,175,595 shares of Company common stock from Credit Suisse pursuant to the Confirmation Documents at a cash price of $35.42 per share, or a total purchase price of $325 million.

The Notice of Commitment also notified Credit Suisse of the irrevocable election by the Company of physical settlement (i.e., purchase and sale of shares of Company common stock rather than settlement for cash) in the event of Credit Suisse’s exercise of its call options under the Confirmation. As a result, Credit Suisse has the option to purchase up to 9,175,595 shares of Company common stock from the Company at $70.00 per share on July 23, 2007, and Credit Suisse’s option, if exercised, will not be settled for cash.

The foregoing descriptions of the Confirmation, the Notice of Adjustment and the Notice of Commitment are qualified by reference to the full text of the Confirmation, the Notice of Adjustment and the Notice of Commitment, copies of which are filed herewith as Exhibits 10.1, 10.2 and 10.3, respectively, and incorporated herein by reference.

To the extent applicable, the contents of Item 1.01 above are incorporated into this Item 2.03 by this reference.

On May 31, 2007, the Company issued a press release announcing its issuance of the Notice of Commitment to Credit Suisse and its closing of a credit facility with Perry Principals Investments LLC, an affiliate of Perry Corp, a significant beneficial owner of the Company’s shares, providing for a loan of $400 million bearing interest at a fixed rate of 9.75% per annum and maturing on May 31, 2012, a portion of the proceeds from which will be used to fund the $325 million repurchase of outstanding Company shares from Credit Suisse. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated by reference herein.
