Ameristar Casinos, Inc. Announces Increase of Consent Fee, Extension of 
Expiration Time and Other Amendments to Consent Solicitation
Relating to 7.50% Senior Notes Due 2021 
LAS VEGAS, NV -- (Marketwire) -- 03/25/13 --  Ameristar Casinos, Inc.
(NASDAQ: ASCA) ("Ameristar") announced today that, pursuant to a
supplement dated March 25, 2013 (the "Supplement") to the Consent
Solicitation Statement dated March 18, 2012 (the "Consent
Solicitation Statement"), at the request and expense of Pinnacle
Entertainment, Inc. ("Pinnacle"), it has amended the terms of its
previously announced consent solicitation (the "Consent
Solicitation") seeking consents from holders of the $1,040,000,000
outstanding principal amount of its 7.50% Senior Notes due 2021 (the
"Notes") for waivers (the "Proposed Waivers") of and amendments (the
"Proposed Amendments") to certain provisions of the indenture
governing the Notes (the "Indenture"). Ameristar commenced the
Consent Solicitation at the request and expense of Pinnacle in
connection with the previously announced proposed merger between
Ameristar and Pinnacle (the "Merger"). 
Pursuant to the Supplement, Ameristar has increased the consent fee
payable to consenting holders from $10.00 to $19.00 for each $1,000
in principal amount of the Notes for which consents are validly
delivered and unrevoked on or prior to the Expiration Time, 50% of
which will be payable promptly after the Expiration Time and the
remaining 50% of which will be payable, if at all, promptly after the
date of the consummation of the Merger, subject, in each case, to the
conditions described in the Consent Solicitation Statement. 
In addition, the Consent Solicitation, which was previously scheduled
to expire at 5:00 p.m., New York City time, on March 27, 2013, has
been further extended to 5:00 p.m., New York City time, on April 2,
2013, unless further extended or terminated by Ameristar. 
The amended terms of the Consent Solicitation also would reduce the
capacity of Pinnacle, as the successor to Ameristar under the
Indenture upon consummation of the Alternative Merger and
Post-Effective Merger (as such terms are defined in the Consent
Solicitation Statement), to make certain restricted payments under
the Indenture from and after the effective time of the Post-Effective 
Merger. The amended terms of the Consent Solicitation also amend and
supplement other terms of the Consent Solicitation Statement as
described in the Supplement.  
All other terms and conditions of the Consent Solicitation, as set
forth in the Consent Solicitation Statement and the Consent Letter,
in each case, as amended and supplemented by the Supplement, remain
the same. Holders of the Notes who have previously delivered consents
do not need to redeliver such consents or take any other action in
response to this announcement in order to receive the increased
consent fee upon the successful conclusion of the Consent
Solicitation and any such previously delivered consents shall be
deemed to include a consent to the additional amendments and
supplements contained in the Supplement. Consents (whether previously
or hereafter delivered) may only be revoked in the manner described
in the Consent Solicitation Statement. 
The Consent Solicitation is being made solely on the terms and
subject to the conditions set forth in the Consent Solicitation
Statement and the accompanying Consent Letter, each as amended and
supplemented by the Supplement. Holders of the Notes are urged to
