Project Receives Approval for Full Financing

Dubai World Dismisses Lawsuit Against MGM MIRAGE

LAS VEGAS and DUBAI, United Arab Emirates, April 29 /PRNewswire-FirstCall/ -- MGM MIRAGE (NYSE: MGM) and Dubai World through subsidiary Infinity World, 50/50 joint venture partners in the CityCenter project, today announced that the companies have reached an agreement on a revised joint venture agreement and also reached an agreement with CityCenter's lenders on a comprehensive plan to fully fund the completion of CityCenter for its scheduled opening later this year.

Under the plan, Dubai World and MGM MIRAGE will fund their remaining equity contributions to CityCenter through letters of credit. In addition, CityCenter's lenders will immediately fund the full $1.8 billion senior secured credit facility. Additionally, Dubai World will dismiss its lawsuit filed against MGM MIRAGE in Delaware Chancery Court on March 22, 2009, and Dubai World and MGM MIRAGE will exchange mutual releases.

"We are pleased that MGM MIRAGE and Dubai World, with the strong support of CityCenter's lenders, have agreed to a comprehensive plan for the financing and completion of CityCenter," said Jim Murren, Chairman and CEO of MGM MIRAGE and Chris O'Donnell, Dubai World's Director of the CityCenter joint venture. "CityCenter is now fully funded and on track to open in December 2009," they said.

"CityCenter will be unlike anything anyone has seen in Las Vegas or anywhere else. We are confident in the potential of CityCenter to contribute significantly to our cash flow," said Mr. Murren. "CityCenter is a powerful engine for growth and employment in Las Vegas and Nevada. With all funding in place, we will focus, along with our partner, on planning for an exciting opening in December and continuing to book rooms and conventions. We appreciate greatly the strong support of our lenders, who share our vision as to the importance of this project to the Las Vegas community and the entire state of Nevada."

Mr O'Donnell said, "This agreement provides a stable financial framework for one of the most exciting destination resort development projects ever to be constructed. MGM MIRAGE is the industry's premier luxury hotel, resort and casino developer and operator. We believe CityCenter has a bright future and will benefit both the partners and the local economy, and we look forward to working with MGM management to realize that potential."

    Key terms of the various agreements include:

    --  MGM MIRAGE will be responsible for completion costs to the extent net
        condominium proceeds are less than $243 million and for completion
        costs in excess of the current budget of $8.5 billion.
    --  Dubai World has agreed to fully fund its original sponsor
        contributions to CityCenter, including $135 million in payments
        previously funded by MGM MIRAGE on Dubai World's behalf.  Dubai World
        is relieved of all completion guarantees.
    --  Until the completion of CityCenter, MGM MIRAGE's obligations with
        respect to additional construction costs, if any, will be supported by
        the assets of Circus Circus Las Vegas and certain adjacent land
        through a completion guarantee.
    --  The CityCenter credit facility has been amended as part of the global
        financing plan.  Such amendments include:
        --  The facility will mature on June 30, 2012.
        --  The interest rate margin was increased by 2.00%, though such
            amount is "pay in kind" through September 2010, with additional
            periodic margin increases through the term of the facility.
        --  Condominium proceeds of up to $250 million may be used to pay for
            construction costs; 30% of net condominium proceeds in excess of
            $250 million will be applied to reduce outstanding borrowings
            under the credit facility, with the remaining 70% available as
            distributable cash upon CityCenter satisfying certain performance
            criteria.

        --  Certain financial covenants were modified to provide CityCenter
            with greater flexibility during its first 18 months of operations.
