MGM MIRAGE (NYSE: MGM) today introduced its world-class team of architects and designers giving shape to Project CityCenter and offered up first glimpses of an unprecedented sustainable vertical city, at an approximate cost of $5 billion, that will redefine the Las Vegas experience and influence contemporary urban design throughout the world.

"A paradigm-shifting project fueled by the vision, diversity and resources of MGM MIRAGE demands a team of respected architects and designers, and we have put them to work to give form to an urban experience like none other in Las Vegas," said Terry Lanni, Chairman and Chief Executive Officer of MGM MIRAGE. "Project CityCenter confirms a cultural and lifestyle revival of city living, reaffirms the growing sophistication and maturity of Las Vegas and sets a benchmark for new growth and exciting new experiences as the city moves into its next 100 years."

Led by renowned architects Cesar Pelli, Rafael Vinoly, Sir Norman Foster, James KM Cheng and Kohn Pedersen Fox Associates, architecture, design and construction teams met with reporters this week in Las Vegas following three days of meetings to share concepts, ideas and passion for Project CityCenter. The project features a stunning 60-story, 4,000-room hotel/casino, two 400-room, non-gaming hotels, about 500,000 square feet of retail shops, dining and entertainment venues and 1,640 units of luxury condominiums.

Some of the world's top design, architectural and construction partners will be involved in Project CityCenter. At a news conference today, Robert Baldwin, President and CEO of Mirage Resorts, Inc. formally introduced the project's primary architectural and design team, which includes:

   *  Cesar Pelli and Associates -- Pelli, the noted architect responsible
      for a range of award-winning projects, including the world's tallest
      buildings, the Petronas Towers in Kuala Lumpur, will be the lead
      architect on Project CityCenter's 4,000-room hotel and casino.

   *  Rafael Vinoly Architects -- The international firm behind such
      projects as the Kimmel Center in Philadelphia and Nasher Museum of Art
      at Duke University, RVA will design a 1,000-unit residential/hotel
      tower at Project CityCenter.

      Vancouver, British Columbia, and will design a 100-unit residential

      exterior architecture for Project CityCenter's free-standing,
      non-gaming luxury hotel.

      most notable gourmet restaurants, will be the principal designer of
      the luxury hotel.

   *  Foster and Partners -- London-based Foster and Partners and its
      principal architect, Sir Norman Foster, a Pritzker Architecture Prize
      winner, will design the exterior of the second non-gaming hotel at
      Project CityCenter, which will be operated by The Light Group.

   *  The Light Group -- Andrew Sasson's company, creators of the immensely
      popular Light and Caramel nightclubs at Bellagio, will provide the
      creative vision and operate Project CityCenter's innovative,
      service-focused hotel.

Gensler, executive architect for Project CityCenter, is responsible for providing project leadership for the entire master plan and program, and is teamed with MGM MIRAGE's Design Group to coordinate and collaborate with the residential developers, hotel operators, retailers and architects. Additionally, HKS Architects is the architect of record for the hotel/casino, Leo A Daly is the architect of record for the residential areas and Adamson Associates is the architect of record for the two non-gaming hotels.

Project CityCenter, the largest privately financed development in the United States, is nearly halfway through a 20-month design process and is scheduled to open in late 2009. The Perini Building Company is lead contractor on the project, with Tishman Construction Corporation serving as the executive construction manager. The two firms have participated in several Las Vegas projects and have more than 220 years of combined construction experience.

"Project CityCenter will benefit immensely from our collaborative and integrated design approach in boosting efficiencies in operation and in developing new technologies that boost sustainability, while customizing the look of this new Las Vegas experience," said Mr. Baldwin.

Charting a new course for responsible growth in Las Vegas, MGM MIRAGE also announced its plans to pursue Leadership In Energy and Environmental Design (LEED) certification at Project CityCenter. The 18-million square foot, multi-use project will incorporate elements designed to make it one of the world's largest environmentally sustainable urban communities.

From garden roofs to the use of reclaimed water, to the creation of a central, on-site power plant, Project CityCenter is being designed to promote the most responsible use of water, electricity and natural gas. MGM MIRAGE will pursue LEED certification for the project, implementing to the highest degree possible generally accepted criteria for sustainable construction outlined by the U.S. Green Building Council.

In a related announcement today, Mr. Baldwin said MGM MIRAGE has reached a $100 million agreement with Siemens to design and build a central energy plant to help power and cool Project CityCenter, as well as delivering other building and communications technologies to improve operational efficiencies and conservation.

"Designing Project CityCenter with sustainable elements reinforces its permanence and creates a healthier environment for our future tenants and guests, as well as for the 12,000 people who will ultimately work at Project CityCenter," Mr. Baldwin said.

To assist MGM MIRAGE in attracting top-flight retail tenants to Project CityCenter's retail district, Mr. Baldwin announced today its plan to partner with Bloomfield Hills, Mich.-based Taubman Centers, Inc, one of the country's premiere, high-end retail developers with more than 50 years of experience.

In keeping the company's long-standing commitment to diversity, MGM MIRAGE also announced that all architects and contractors will share its commitment to include minority, disadvantaged and women owned businesses in their substantial and meaningful participation on Project CityCenter. Wholly minority owned firms for CityCenter include Cesar Pelli, Rafael Vinoly, James KM Cheng and Hamilton Anderson out of Detroit, which has formed a joint venture with Leo A Daly.
