On April 19, 2006, Aztar Corporation published the following press release:

                          AZTAR AMENDS MERGER AGREEMENT
             WITH PINNACLE ENTERTAINMENT TO INCREASE PURCHASE PRICE

PHOENIX, AZ, April 19, 2006 - Aztar Corporation (NYSE: AZR) announced today that
it has amended its merger agreement with Pinnacle Entertainment, Inc. Pursuant
to the amended merger agreement, the purchase price for each share of Aztar
common stock has been increased to $43.00 in cash and the purchase price for
each share of Aztar Series B preferred stock has been increased to $454.79 in
cash. The termination fee ($42 million) and the termination expenses (up to $13
million) in the merger agreement remain unchanged.

Aztar also announced today that its Board of Directors has determined, after
consultation with its legal and financial advisors, that the previously
announced unsolicited proposal to acquire Aztar's common stock for a price of
$47 in cash received from Wimar Tahoe Corporation, d/b/a Columbia Entertainment,
the gaming affiliate of Columbia Sussex Corporation, continues to be reasonably
likely to result in a superior proposal, as defined in the merger agreement with
Pinnacle, as amended on April 18, 2006. Based on the determination of Aztar's
Board that Columbia Entertainment's proposal continues to be reasonably likely
to result in a superior proposal compared to the amended agreement with
Pinnacle, Aztar's Board has authorized Aztar to continue discussions with
Columbia Entertainment.

Aztar's Board will continue to evaluate all aspects of the proposal from
Columbia Entertainment, and there can be no assurance that the proposal from
Columbia Entertainment will result in a definitive offer or, if such offer is
made, that it would be accepted by Aztar's Board of Directors.
