On April 17, 2006, Aztar Corporation published the following press release:


                    AZTAR CORPORATION PREPARED TO ENTER INTO
          DISCUSSIONS WITH COLUMBIA ENTERTAINMENT; RECEIVES DEFINITIVE
                          OFFER FROM AMERISTAR CASINOS


PHOENIX, AZ, April 17, 2006 - Aztar Corporation (NYSE: AZR) today announced that
its Board of Directors, after consultation with its legal and financial
advisors, has determined that an unsolicited proposal received from Wimar Tahoe
Corporation, d/b/a Columbia Entertainment, the gaming affiliate of Columbia
Sussex Corporation, is, or is reasonably likely to result in, a superior
proposal, as defined in Aztar's merger agreement, dated March 13, 2006, with
Pinnacle Entertainment, Inc. Based on this determination that the proposal by
Columbia Entertainment is, or is reasonably likely to result in, a superior
proposal compared to the agreement with Pinnacle, Aztar's Board has determined
to authorize Aztar to enter into discussions with Columbia Entertainment.

On April 13, 2006, Columbia Entertainment made an unsolicited proposal to
acquire Aztar in a merger transaction in which the holders of Aztar common stock
would receive $47.00 per share in cash and the holders of Aztar's Series B
preferred stock would receive a commensurate payment dictated by the terms of
the securities. Columbia Entertainment's proposal is non-binding and is
conditioned upon, among other things, confirmatory due diligence.

Aztar also announced today that on April 14, 2006, it received a definitive
offer from Ameristar Casinos, Inc. to acquire Aztar in a merger transaction in
which the holders of Aztar common stock would receive $43 per share in cash and
the holders of Aztar's Series B preferred stock would receive $454.79 per share
in cash. The definitive offer included a signed merger agreement and a signed
financing commitment letter.

As previously announced, Aztar is party to a merger agreement with Pinnacle,
under which each share of Aztar common stock would be exchanged for $38.00 in
cash and each share of Aztar Series B preferred stock would be exchanged for
$401.90 in cash. The transaction with Pinnacle is subject to approval by Aztar's
shareholders and the satisfaction of customary closing conditions, including the
receipt of necessary regulatory and governmental approvals.

Aztar's Board will evaluate all aspects of the proposal from Columbia
Entertainment (including any financing commitment letter yet to be provided to
Aztar), the definitive offer from Ameristar and the previously announced
proposal from Colony Capital Acquisitions, LLC. Aztar's Board is not making any
recommendation at this time with respect to any such proposal or offer, and
there is no assurance that the Aztar Board will approve any such transaction or
that a transaction will result.
