MGM Mirage and Infinity World provide update

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

Based on the preliminary count, subject to final verification and conditional tenders, 101,906,722 shares of MGM Mirage's common stock were tendered, including 19,225,965 shares which were tendered through Notices of Guaranteed Delivery. 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tendered upon the condition of a minimum number of shares being purchased in the joint tender offer will be deemed withdrawn in the event that such condition is not satisfied as a result of proration.

MGM Mirage and Infinity World (Cayman) L.P. expect to purchase 15,000,000 shares of MGM Mirage's common stock in the joint tender offer, with MGM Mirage purchasing 8,500,000 of such shares and Infinity World (Cayman) L.P. purchasing 6,500,000 of such shares, at a purchase price of $80.00 per share, for a total purchase price of $1,200,000,000. Because the number of shares tendered exceeded the number of shares that MGM Mirage and Infinity World (Cayman) L.P. offered to purchase, the resulting estimated proration factor is approximately 14.7% of the shares tendered.

The number of shares tendered and not withdrawn and the proration factor are preliminary and are subject to verification. The actual number of shares validly tendered and not withdrawn and the final proration factor will be announced promptly following completion of the verification process.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.
