In addition, Ader will provide copies of the definitive proxy statement and accompanying proxy card (when available) without charge upon request. As of the date hereof: ALSF and Doha directly beneficially own 699,148 shares of common stock of the Company ("Shares") and 97,800 Shares, respectively (AIM, as investment manager to ALSF and Doha, is also deemed to beneficially own such Shares); AIM beneficially owns an additional 438,859 Shares which are held in accounts over which AIM has discretionary investment authority (including 300,000 Shares held in an account of an affiliate of Mr. Mathewson); AIM beneficially owns an additional 6,764,389 Shares by virtue of having been granted proxy voting authority over such Shares (including 752,325 Shares over which Mr. Mathewson has granted AIM proxy voting authority); Mr. Silvers is the President of the Managing Member and AIM, and directly beneficially owns 43,423.221 Shares for his benefit and the benefit of his family; Mr. Nelson is the Chief Financial Officer of the Managing Member and AIM, and directly beneficially owns 8,052.7309 Shares; Ms. Conover is the Chief Operating Officer and Chief Compliance Officer of the Managing Member and AIM, and directly beneficially owns 2,217.6298 Shares. The General Partner is the general partner of AIM, ALSF and Doha, and thus is deemed to have beneficial ownership of the Shares beneficially owned by AIM, ALSF and Doha. The Managing Member is the managing member of the General Partner, and thus is deemed to have beneficial ownership of the Shares beneficially owned by the General Partner.

Accordingly, each Group Member (1) may be deemed to have beneficial ownership of the Shares beneficially owned by the other Group Members and (2) thus may be deemed to beneficially own 8,053,889.5817 Shares in the aggregate. Each Group Member disclaims beneficial ownership of the Shares he, she or it does not directly own. Mr. Brooks does not have beneficial ownership of any Shares.
