("BVI") and The Raptor Global Portfolio Ltd. ("Raptor"), and the General Partner of The Altar Rock Fund L.P. ("Altar Rock"). The shares of Common Stock (collectively, "Common Stock") as reported herein as indirectly beneficially owned by TIC are directly beneficially owned by BVI (368,855 shares), Raptor (1,107,917 shares), and Altar Rock (9,862 shares). Because TIC is the sole General Partner of Altar Rock and provides investment-advisory services to BVI and Raptor, TIC may be deemed to beneficially own the shares of Common Stock owned by each of such entities. TIC disclaims beneficial ownership of the securities reported herein as indirectly owned except to the extent of its pecuniary interest in such securities.

Mr. Pallotta expressly disclaims such beneficial ownership.
5. The shares of Common Stock as reported herein as indirectly beneficially owned by TIC are directly beneficially owned by BVI (58,496 shares), Raptor (189,827 shares), and Altar Rock (1,677 shares). Because TIC is the sole General Partner of Altar Rock and provides investment-advisory services to BVI and Raptor, TIC may be deemed to beneficially own the shares of Common Stock owned by each of such entities.

6. The shares of Common Stock (the "Shares") are reported herein as indirectly beneficially owned by Paul Tudor Jones II. The Shares are owned indirectly by TIC (250,000 shares) (see Footnote 5).
