MGM MIRAGE ENTERS INTO AN AMENDMENT TO ITS SENIOR CREDIT FACILITY

Company Secures Approval To Fund Its Share Of CityCenter Equity Contributions
And Extends Waiver Period Through June 30, 2009

LAS VEGAS, April 29 /PRNewswire-FirstCall/ -- MGM MIRAGE (NYSE: MGM) today
announced that it has entered into an amendment to its senior credit facility,
including a waiver through June 30, 2009, of the requirement that the Company
comply with the senior credit facility's financial covenants.

Under the terms of the amendment and waiver, the Company will be able to
fulfill its remaining equity contributions to CityCenter through the issuance
of an irrevocable letter of credit in the amount of $224 million. The Company
is also permitted to enter into revised completion guarantees related to
CityCenter.

"Our company's ability to obtain this amendment and waiver demonstrates the
strong support of our lenders, and their belief in the importance of
completing CityCenter," said Jim Murren, Chairman and Chief Executive Officer
of MGM MIRAGE. "We continue to work with our advisors and lenders to reach a
long-term restructuring of MGM MIRAGE's indebtedness and those discussions
remain positive and constructive. Our next step will be to finalize our
restructuring plans and position MGM MIRAGE for future growth and success."

Under the terms of the amendment, the Company repaid $100 million under the
senior revolving credit facility, which amount is not available for
re-borrowing without the consent of the requisite lenders. In addition, the
Company has agreed to grant the lenders security interests in the assets of
Gold Strike Tunica and certain undeveloped land on the Las Vegas Strip,
subject to requisite gaming and other approvals, to secure debt under the
facility in an amount up to $300 million. MGM Grand Detroit, which is a
co-borrower under the senior credit facility, has agreed to grant the lenders
a security interest in its assets to secure its borrowings under the facility,
subject to gaming and other approvals.

The Company intends to work with its lenders to obtain additional waivers or
amendments prior to June 30, 2009 to address future noncompliance with the
senior credit facility; however, the Company can provide no assurance that it
will be able to secure such waivers or amendments. If additional waivers or
amendments are not obtained, following expiration of the waiver on June 30,
2009, the Company will be subject to an event of default related to any
noncompliance with financial covenants under the senior credit facility.
Under the terms of the senior credit facility, noncompliance with financial
covenants is an event of default, allowing the lenders (with a vote of lenders
holding more than 50% of the borrowings outstanding under the senior credit
facility) to exercise any or all of their remedies, including demanding
immediate repayment of all outstanding borrowings under the senior credit
facility. In addition, there are provisions in the indentures governing the
Company's senior and senior subordinated notes under which a) the event of
default under the senior credit facility, or b) the exercise of remedies under
an event of default under the senior credit facility, would cause an event of
default under the relevant senior and senior subordinated notes, which would
also allow holders of the senior and senior subordinated notes to demand
immediate repayment and decline to release subsidiary guarantees. If the
lenders exercise any or all such rights, the Company may determine to seek
relief through a filing under the U.S. Bankruptcy Code.

Statements in this release which are not historical facts are "forward
looking" statements and "safe harbor statements" under the Private Securities
Litigation Reform Act of 1995 that involve risks and/or uncertainties,
including risks and/or uncertainties as described in the company's public
filings with the Securities and Exchange Commission.
