Under the procedures for the Tender Offer, MGM MIRAGE's stockholders will have the opportunity to tender some or all of their shares at a price of $80.00 per share. If more than 15,000,000 shares are properly tendered and not withdrawn, then MGM MIRAGE and Infinity World will purchase shares on a pro rata basis, subject to the conditional tender offer provisions that will be described in the offer to purchase that will be distributed to stockholders. Stockholders whose shares are purchased in the offer will be paid the $80.00 per share price net in cash, without interest, after the expiration of the offer period. The offer is not contingent upon any financing condition or any minimum number of shares being tendered. The offer is subject, however, to a number of other customary terms and conditions to be specified in the offer to purchase that will be distributed to stockholders. No brokerage fees or commissions will be charged to holders who tender their shares.

Neither MGM MIRAGE, its Board of Directors, nor Dubai World and its affiliates are making any recommendation to stockholders as to whether to tender or refrain from tendering their shares into the tender offer. Stockholders must decide how many shares they will tender, if any.
