MGM Mirage, Infinity World releases update

LAS VEGAS, Nevada -- (PRESS RELEASE) -- MGM Mirage (NYSE: MGM) and Infinity World (Cayman) L.P., an indirect wholly owned subsidiary of Dubai World, announced today updated preliminary results of their joint tender offer, which expired at 12:00 midnight, New York City time, on February 14, 2008.

Subsequent to the announcement earlier today of the preliminary results of the joint tender offer, Mellon Investor Services LLC, the depositary for the joint tender offer, advised MGM MIRAGE and Infinity World (Cayman) L.P. that it had failed to include in its final report of the preliminary results of the joint tender offer an additional 7,467,169 shares tendered through Notices of Guaranteed Delivery.

Based on the updated preliminary count, subject to final verification and conditional tenders, approximately 109,373,891 shares of MGM MIRAGE's common stock were tendered, including approximately 26,693,134 shares which were tendered through Notices of Guaranteed Delivery, resulting in an updated estimated proration factor of approximately 13.7% instead of 14.7%. Any shares tendered upon the condition of a minimum number of shares being purchased in the joint tender offer will be deemed withdrawn in the event that such condition is not satisfied as a result of proration.

The number of shares tendered and not withdrawn and the proration factor are preliminary and are subject to verification. The actual number of shares validly tendered and not withdrawn and the final proration factor will be announced promptly following completion of the verification process. Promptly after such announcement, the depositary will issue payment for the shares validly tendered and accepted under the joint tender offer and will return all other shares tendered.
