ASCA A SPAC I Acquisition Corporation

Ameristar Casinos, Inc. (NASDAQ: ASCA) announced today that it has extended the maturity date of $600 million of revolving loan commitments under its senior secured credit facility from November 10, 2010 to August 10, 2012. Based on the Company's current leverage ratio, the new 2012 revolving loan tranche, under which $514.4 million of loans are currently outstanding, is priced 37.5 basis points higher than the preexisting 2010 revolving loan tranche. The $150 million of non-extending revolving commitments comprising the 2010 tranche, under which $128.6 million of loans are currently outstanding, remain currently priced at 287.5 basis points over LIBOR. In connection with obtaining the extensions, the Company paid the joint lead arrangers and extending lenders approximately $6.7 million in one-time fees.

"This 21-month extension of the maturity date of 80% of our revolving loan commitments, coupled with our issuance last May of $650 million of senior unsecured notes due in June 2014, provides us with the flexibility to continue to successfully operate our business and defer the complete refinancing of our bank credit facilities in these difficult economic times," said Gordon Kanofsky, Ameristar's Chief Executive Officer. "We are grateful for the support of our lenders and believe it reflects the confidence they have in our Company. We expect the Company will generate sufficient operating cash flow to retire the 2010 tranche of the revolving loan commitments upon their maturity," Kanofsky added.

Wells Fargo Securities, LLC, Banc of America Securities LLC, Deutsche Bank Securities Inc. and US Bank National Association acted as joint lead arrangers and joint book runners with respect to the extending revolving commitments.
