         The information required by Items 4(a) - (c) is set forth in Rows 5 -
         11 of the cover page for each Reporting Person hereto and is
         incorporated herein by reference for each such Reporting Person. Based
         on the Notification of Repurchase Offer filed pursuant to Rule 23C-3 on
         Form N-23C-3 on March 10, 2008, the total number of outstanding shares
         of Common Stock as of March 4, 2008 is 20,055,720.

         As of March 31, 2008, (i) Hudson Bay Fund, LP beneficially owned
         423,193 shares of Common Stock, (ii) Hudson Bay Overseas Fund, Ltd.
         beneficially owned 690,489 shares of Common Stock and (iii) each of the
         Reporting Individuals and the Investment Manager may have been deemed
         the beneficial owner of the 1,113,682 shares of Common Stock
         beneficially owned by the Hudson Bay Funds.

         Therefore as of March 31, 2008, (i) Hudson Bay Fund, LP beneficially
         owned 2.11% of the outstanding shares of Common Stock of the Company,
         (ii) Hudson Bay Overseas Fund, Ltd. beneficially owned 3.44% of the
         outstanding shares of Common Stock of the Company and (iii) each of the
         Reporting Individuals and the Investment Manager may have been deemed
         to beneficially own 5.55% of the outstanding shares of Common Stock of
         the Company. The foregoing should not be construed in and of itself as
         an admission by any Reporting Person as to beneficial ownership of
         shares of Common Stock owned by another Reporting Person.

         Since March 31, 2008, the Hudson Bay Funds sold a portion of their
         shares of Common Stock such that as of the date hereof, the Reporting
         Persons ceased to be the beneficial owner of 5% of the shares of
