MGM MIRAGE Announces Amended Development Agreement in Detroit

April 22, 2002

MGM MIRAGE (NYSE: MGG) announced today that it has entered into an amended Development Agreement with the City of Detroit providing for the construction of a permanent hotel/casino complex in Detroit. The amended Development Agreement and the site of the new casino complex are subject to the approval of Detroit's City Council. Although the site for the permanent MGM Grand Detroit has not yet been determined, MGM MIRAGE is considering several alternatives.

The new facility will initially have 400 first class hotel rooms, with an additional 400 rooms to be built at a future time depending on market demand. The casino will be at least as large as the MGM Grand Detroit's interim casino, which will continue to operate until the new complex is opened. The target date for completion is December 2005, in time to provide accommodations for the Super Bowl to be hosted by Detroit in early 2006.

John Redmond, President and Chief Executive Officer of MGM Grand Resorts, said "We are very pleased to have reached an agreement with the City on a program which, if approved by the City Council, will enable us to move forward expeditiously with our new facility. We believe that with permanent hotel/casino facilities in Detroit, there is great potential to expand the Detroit market and to further enhance our participation in the development and growth of the Detroit economy. We appreciate the active involvement of Mayor Kilpatrick and his administration in advancing this project."
