               *The Reporting Persons beneficially own an aggregate of 2,333,333
               shares of Common Stock. The foregoing amount of Common Stock and
               percentage ownership represent the combined indirect holdings of
               Michael A. Roth and Brian J. Stark. The shares of Common Stock
               reported in this Schedule 13G do not include 600,001 shares of
               Common Stock issuable upon the exercise of warrants held by the
               Reporting Persons. Such warrants held by the Reporting Persons
               are subject to conversion caps that preclude the holder thereof
               from utilizing its exercise rights to the extent that it would
               beneficially own (determined in accordance with Section 13(d) of
               the Securities Exchange Act of 1934) in excess of 4.999% of the
               Common Stock, giving effect to such exercise.

               All of the foregoing represents an aggregate of 2,333,333 shares
               of Common Stock held directly by SF Capital Partners Ltd. ("SF
               Capital"). The Reporting Persons are the Managing Members of
               Stark Offshore Management, LLC ("Stark Offshore"), which acts as
               investment manager and has sole power to direct the management of
               SF Capital. Through Stark Offshore, the Reporting Persons possess
               voting and dispositive power over all of the foregoing shares.
               Therefore, for the purposes of Rule 13d-3 under the Exchange Act,
               the Reporting Persons may be deemed to be the beneficial owners
               of, but hereby disclaim such beneficial ownership of, the
               foregoing shares.
