The revised definitive offer included a signed merger agreement. Ameristar also provided a signed financing commitment letter. Ameristar stated in its revised definitive offer that the offer would expire by noon (Las Vegas time) on April 22, 2006, but that if certain conditions were met before that time, this deadline would be extended until 12:01 a.m. (Las Vegas time) on April 27, 2006. The conditions required for the extension include written notification by Aztar to Ameristar before noon (Las Vegas time) on April 22, 2006, that: (1) Aztar's Board has determined that Ameristar's revised definitive offer constitutes a superior proposal (as defined in Aztar's amended merger agreement with Pinnacle Entertainment, Inc.) and has informed Pinnacle of that determination; (2) Ameristar's revised definitive offer is the only superior proposal Aztar has received; and (3) as of the time of the notice to Ameristar, Aztar has received no other takeover proposals (as defined in Aztar's amended merger agreement with Pinnacle) that are reasonably likely to result in a superior proposal. Aztar also announced that its Board, after consultation with its legal and financial advisors, has determined that the revised definitive offer from Ameristar is reasonably likely to result in a superior proposal. Based on such determination, Aztar's Board has authorized Aztar to resume its discussions with Ameristar. Aztar also stated that its Board indicated it is unwilling to discontinue its discussions with Wimar Tahoe Corporation, d/b/a Columbia Entertainment, the gaming affiliate of Columbia Sussex Corporation. As previously announced, Aztar's Board determined on April 18, 2006 that Columbia Entertainment's proposal to acquire Aztar for $47.00 in cash per share of Aztar common stock continued to be reasonably likely to result in a superior proposal, as defined in the amended merger agreement with Pinnacle. Aztar's Board will evaluate all aspects of the revised definitive offer from Ameristar and the proposal from Columbia Entertainment (including any financing commitment letter yet to be provided to Aztar). Aztar's Board is not making any recommendation at this time with respect to any such offer or proposal, and there can be no assurance that Aztar's Board will approve any such transaction or that a transaction will result. As previously announced, on April 18, 2006, Aztar and Pinnacle amended their merger agreement to increase the purchase price for each share of Aztar common stock from $38.00 to $43.00 in cash.
