FOR IMMEDIATE RELEASE

March 13, 2013

Greektown Superholdings, Inc. Provides Regulatory Update

DETROIT, March 13, 2013– Greektown Superholdings, Inc. (“Greektown” or the “company”) reported today that at the March 12, 2013 meeting of the Michigan Gaming Control Board (the “MGCB”), the MGCB approved an amendment to its existing revolving credit facility with Comerica Bank. The amendment extended the term of the credit facility by one year, to December 30, 2014, among other modifications.

At the meeting, the MGCB tabled the company’s request for approval of a temporary suspension of the covenant contained in the MGCB 2010 order requiring the company to maintain a specified minimum ratio of EBITDA to fixed charges. Based upon current estimates, and including projected costs associated with the advisors engaged by the company’s Special Committee of the Board of Directors, the company may not be able to maintain the required minimum ratio of EBITDA to fixed charges for the twelve month measurement period ending March 31, 2013. The company will continue to work with the MGCB to address this matter as soon as possible.
