Explanation of Responses:

Remarks:
The Reporting Persons beneficially own no securities of the Issuer. On October 5, 2010, Razor Holdco Inc. entered into a Voting Agreement with certain investment funds managed by Angelo, Gordon & Co., L.P. (collectively, the "Shareholders"). Pursuant to the Voting Agreement, the Shareholders agreed to vote the shares of the Issuer's Common Stock owned or controlled by them, collectively 4,496,555 shares of Common Stock (equal to approximately 33.2% of the issued and outstanding shares of Common Stock), in favor of that certain Agreement and Plan of Merger, dated October 5, 2010 (the "Merger Agreement"), by and among the Issuer, Razor Holdco Inc. and Razor Merger Sub Inc., and the transactions contemplated by the Merger Agreement. The Shareholders also agreed that they will not dispose or transfer their shares (subject to certain exceptions, including the ability to transfer shares to affiliates that agree to be bound by the terms of the Voting Agreement) until such Voting Agreement is terminated pursuant to its terms. None of the Reporting Persons has any pecuniary interest in any of the shares of Common Stock subject to the Voting Agreement, and each expressly disclaims beneficial ownership of such shares for all purposes.
