                        AZTAR DETERMINES THAT OFFER FROM
                       COLUMBIA ENTERTAINMENT IS SUPERIOR


PHOENIX, AZ, May 1, 2006 - Aztar Corporation (NYSE: AZR) today said that its
Board of Directors has determined that a definitive offer received today from
Wimar Tahoe Corporation d/b/a Columbia Entertainment, the gaming affiliate of
Columbia Sussex Corporation, to acquire Aztar is a superior proposal when
compared to the terms of Aztar's current merger agreement, as amended, with
Pinnacle Entertainment, Inc.

Under the terms of its definitive offer, Columbia Entertainment would acquire
Aztar in a merger transaction in which the holders of Aztar common stock would
receive $50.00 per share in cash and the holders of Aztar's Series B preferred
stock would receive $528.82 per share in cash. The consideration remains
unchanged from the definitive offer Columbia Entertainment made on April 28,
2006, though other terms did change. The definitive offer included a signed
merger agreement. The proposed merger agreement contemplates a substantial
deposit, payable to Aztar in certain circumstances (including failure to obtain
regulatory approvals), in the event that an executed merger agreement, if any,
is terminated. The proposed merger agreement also provides for an increase in
the purchase price at the rate of $0.00822 per share of Aztar common stock (and
$0.08693 per share of Aztar preferred stock) per day beginning six months after
the signing of the merger agreement in the event all required regulatory
approvals have not been received by that date. Columbia Entertainment also
provided a signed financing commitment letter.

Columbia Entertainment stated in its definitive offer that the offer will remain
open until 5:00 p.m. (New York City time) on Friday, May 5, 2006.

Under the terms of Aztar's merger agreement with Pinnacle, Aztar must wait three
business days before it can terminate the merger agreement with Pinnacle and
enter into a merger agreement with another party. As previously announced, Aztar
and Pinnacle amended their merger agreement on April 28, 2006 to increase the
purchase price for each share of Aztar common stock to $45.00 per share in cash
and $3.00 of Pinnacle common stock, subject to a collar.

Aztar's Board is not making any recommendation at this time with respect to the
Columbia Entertainment offer, and there can be no assurance that Aztar's Board
will approve any such transaction or that a transaction will result.
