On April 21, 2006, Aztar Corporation published the following press release:

                        AZTAR RECEIVES REVISED DEFINITIVE
                              OFFER FROM AMERISTAR


PHOENIX, AZ, April 21, 2006 - Aztar Corporation (NYSE: AZR) today announced that
on April 20, 2006, its Board of Directors received a revised definitive offer
from Ameristar Casinos, Inc. to acquire Aztar in a merger transaction in which
the holders of Aztar common stock would receive $45.00 per share in cash and the
holders of Aztar's Series B preferred stock would receive $475.94 per share in
cash. 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.
