The plan for a multi billion dollar resort complex on 72 acre site, in Atlantic City, has been approved. The new resort will have a budget in the $4.5-$5 billion range, not including value of the land and associated costs.

MGM MIRAGE has announced the company's Board of Directors approval of the development of a major resort casino project at Renaissance Pointe in Atlantic City, New Jersey.

The MGM Grand Atlantic City will be located on land the company considers the largest and best-located casino development site in Atlantic City, the 72-acre site at Renaissance Pointe owned by the company, adjacent to the 50% owned Borgata.

The proposed resort will consist of three separate hotel towers in a strikingly unique design. Totaling more than 3,000 rooms and suites, each tower will offer guests a distinctly different hotel experience, sharing the signature amenities of an MGM Grand resort, including:

The largest casino floor in Atlantic City with 5,000 slot machines, 200 table games and a large poker room; a 1,500-seat state-of-the-art theater; a variety of restaurant, nightclub and entertainment concepts; a spacious, world-class contemporary spa; a 500,000 square foot retail experience and a modern and versatile convention center.

"Our company has carefully considered the possibilities for our landholdings in Atlantic City," said Terry Lanni, Chairman and CEO of MGM MIRAGE. "We believe the success at Borgata demonstrates the eagerness for further evolution of the nation's second-largest gaming market.

We will continue to raise the bar, and by doing so, hope to re-energize the city's resort offerings and attract a new market of affluent East Coast customers.

We believe our new resort will generate very healthy returns for ourshareholders."

With its unique design and iconic shape, the resort will become the city's tallest building and will dominate the architectural skyline of Atlantic City. In addition to the dramatic statement made by the resort's three towers, designed by world-renown architects Kohn Pedersen Fox, the resort will include spectacular interior features designed by the highly
innovative Rockwell Group and other leading designers.

The company intends to file for Coastal Area Facility Review Act (CAFRA) approval in late 2007 or early 2008. Ground breaking is expected in 2008, with an anticipated opening in 2012. Approximately 60 acres of the site will be used for construction of MGM Grand Atlantic City, with 12 acres reserved for future development, which may include a residential
component.

The company also owns an additional 14-acre site in the Marina District. These cost estimates and the design and scope of MGM Grand Atlantic City are preliminary and subject to change.
