MGM RESORTS INTERNATIONAL ANNOUNCES PRICING OF $1.5 BILLION
SENIOR SECURED NOTES OFFERING BY CITYCENTER HOLDINGS, LLC

Las Vegas, Nevada, January 14, 2011 — MGM Resorts International (NYSE: MGM) announced today that CityCenter Holdings, LLC priced $900 million aggregate principal amount of 7.625% senior secured first lien notes due 2016 and $600 million aggregate principal amount of 10.75% senior secured second lien PIK toggle notes due 2017. The interest rate on the senior secured second lien notes increases by 0.75% if CityCenter elects to pay interest in the form of additional debt. These transactions are expected to close on January 21, 2011.

CityCenter Holdings, LLC is a 50/50 joint venture of MGM Resorts International and Infinity World Development Corp. (a wholly owned subsidiary of Dubai World).

CityCenter plans to use the net proceeds from the offering, together with equal equity contributions from its owners totaling approximately $77 million, to reduce the principal balance of its existing senior secured credit facility from approximately $1.85 billion to $500 million, to establish an interest escrow for first lien indebtedness and to pay fees and expenses. The remaining $500 million balance of its senior secured credit facility will be extended to January, 2015 under an amended and restated senior secured credit facility. This senior secured credit facility will be pari passu with the 7.625% senior secured first lien notes.

The notes have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws and may not be offered or sold in the United States or to any U.S. persons absent registration under the Securities Act, or pursuant to an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws. The notes will be offered only to “qualified institutional buyers” under Rule 144A of the Securities Act or, outside the United States, to persons other than “U.S. persons” in compliance with Regulation S under the Securities Act.

This press release does not constitute an offer to sell or a solicitation of an offer to buy the notes, nor shall there be any offer, solicitation or sale of any notes in any jurisdiction in which such offer, solicitation or sale would be unlawful. The Company gives no assurance that the proposed offering by CityCenter can be completed on any terms.
