On the morning of May 4, the Reporting Persons filed a complaint against the
Company, Seth Bernstein, Chatham Capital and Chatham Investment Fund III,
L.L.C., in the Circuit Court of Cook County, Illinois County Department,
Chancery Division (the "Chancery Court") seeking injunctive and declaratory
relief to enforce the terms of (i) the exclusivity provisions set forth in
section 1 of the letter agreement by and between the Reporting Persons and the
Issuer dated as of April 17, 2007 (the "April 17 Letter") with respect to the
purchase of the business of Empagio, Inc., a wholly owned subsidiary of the
Issuer, and (ii) the expense reimbursement provisions set forth in section 2 of
the April 17 Letter. In addition, the Reporting Persons have requested temporary
relief from the Circuit Court to restrain the Issuer, Mr. Bernstein and the
Chatham entities from ongoing violation of the exclusivity provisions of the
April 17 Letter or from having any further discussions or negotiations or taking
any further action or entering into any further agreement with respect to any
Alternative Transaction (as defined in the April 17 Letter). The Reporting
Persons remain willing to proceed with their efforts to accomplish the
Transaction set forth in the April 17 Letter. The Reporting Persons reserve all
legal and other rights and remedies available to them with respect to any
breaches with respect to the April 17 Letter, including by any third parties, or
otherwise with respect to the Issuer or a transaction involving Empagio.
