Dubai World and MGM MIRAGE to form long-term strategic relationship

Dubai World and MGM MIRAGE (NYSE: MGM) today announced that they have signed definitive agreements to form a long-term strategic relationship whereby Dubai World will invest approximately USD5 billion in MGM MIRAGE consisting of a USD2.7 billion investment in CityCenter and up to USD2.4 billion in purchases of MGM MIRAGE common stock.

The joint venture, CityCenter Holdings LLC, will be owned equally by MGM MIRAGE and Infinity World Development Corp., a wholly-owned subsidiary of Dubai World.

Upon closing, CityCenter Holdings LLC will own 100 percent of CityCenter, a mixed-use luxury residential, resort and retail complex currently being developed by MGM MIRAGE on the Las Vegas Strip.

In addition to investing in the joint venture, Dubai World through Infinity World Investments, will purchase up to 28.4 million shares of MGM MIRAGE representing approximately a 9.5 percent equity stake.

Dubai World will seek to accomplish this through a combination of a public tender offer for 14.2 million shares of the outstanding stock at a price of $84 per share, which represents an approximately 13% premium over yesterday's closing price, and an agreement to subsequently purchase an additional 14.2 million shares directly from the Company at the same price, for a combined investment of approximately $2.4 billion.

The companies anticipate that the joint venture investment will close by the end of the year, and that the tender offer will commence during the week of August 27, 2007.

The parties anticipate that the purchase of shares from MGM MIRAGE will close concurrently with or soon after the closing of the tender offer subject to requisite approvals.

In connection with the joint venture, Dubai World will initially contribute approximately $2.7 billion for 50 percent of the equity in CityCenter.

MGM MIRAGE will contribute the CityCenter assets which the parties have mutually valued at $5.4 billion, and receive 50 percent of the equity in CityCenter.

Following the close of the joint venture transaction, MGM MIRAGE will receive a cash distribution of $2.7 billion.

By completing CityCenter on budget and on schedule, MGM MIRAGE will receive additional consideration of $100 million. The joint venture will obtain project specific financing to fund remaining project costs.

MGM MIRAGE will continue to serve as developer of CityCenter and upon completion, the joint venture will pay MGM MIRAGE a management fee to operate CityCenter's resort as well as the development's retail activities and the Vdara condo-hotel tower.
