Explanation of Responses:
( 1)	The Reporting Person is the managing member of Knott Partners Management, LLC, which is (i) the sole general partner of Shoshone Partners, L.P., Knott Partners Offshore Master Fund, L.P., and Mulsanne Partners, L.P. and (ii) the managing general partner of Knott Partners, L.P.
( 2)	The Reporting Person is the sole director and the president of Dorset Management Corporation, which (i) provides investment management services to Knott Partners Offshore (SRI) Fund Limited and (ii) separate institutional managed accounts (each, a "Managed Account").
( 3)	As a result of the Reporting Person's interests in Knott Partners Management, LLC and in Dorset Management Corporation, the Reporting Person has investment discretion and control of the securities in this entry. The Reporting Person may be deemed to beneficially own an indirect pecuniary interest in securities in this entry as a result of a performance related fee. Except with respect to Knott Partners, L.P., Knott Partners Offshore Master Fund, L.P., and Shoshone Partners, L.P., in which the Reporting Person owns a beneficial interest, the Reporting Person disclaims beneficial ownership therein except to the extent ultimately realized. Each of Knott Partners, L.P., Knott Partners Offshore Master Fund, L.P., Shoshone Partners, L.P., Mulsanne Partners, L.P., Knott Partners Offshore (SRI) Fund Limited and each of the Managed Accounts disclaims beneficial ownership of securities reported as owned by any other party.
( 4)	The derivative securities listed in column 1 of Table II are currently exercisable or convertible, as the case may be.
( 5)	Each entry reflects a component of the transactions covered by a stock purchase agreement entered into with the Issuer, and which included (a) the cash pre-payment of Convertible Notes expiring in 2013 described in Column 1 of Table II of this Report, (b) a cashless exchange of warrants for Common Stock of the Issuer and (c) the simultaneous disposition of all Common Stock beneficially held, whether previously owned or acquired in the cashless exchange of warrants (the "Securities Transaction"). The purchase price paid by the Issuer for the Common Stock is subject to hold-back and for which an established amount cannot at this time be determined. The Securities Transaction was approved by the Issuer's board of directors and closed on July 1, 2010.
