(1) This is a joint filing by MJX Flag Associates, LLC ("MJX"), Flag Luxury Properties, LLC ("FLP"); LMN 134 Family Company LLC ("LMN134"); FC208, LLC ("FC208"); Metro Investment, LLC ("Metro Investment"); TTERB Living Trust dated 6/20/2000 ("TTERB"); Mitchell J.

(2) (continued from footnote 1) On May 3, 2007, the equity interests in RH1, LLC ("RH1") formerly held by Metro Investment were transferred to Flag Leisure Group, LLC ("FLG"). FLG is the managing member of FLP and is owned in equal one-third interests by MJX Real Estate Ventures ("MREV") (formerly named Sillerman Real Estate Ventures, LLC), Paul Kanavos, and Brett Torino. Upon completion of such transfer, Metro Investment may be deemed to be the beneficial owner of 0 shares of Common Stock. Also upon completion of such transfer, FC208 and TTERB, former direct and indirect owners of equity interests in Metro Investment, may be deemed to be the beneficial owners of 0 shares of Common Stock.
(3) After the transaction described in footnote 2, MJX no longer has an indirect equity interest in RH1, and MJX does not have a direct or indirect control relationship with RH1. Therefore, MJX is no longer deemed to indirectly beneficially own the 418,294 shares of Common Stock directly beneficially owned by RH1. After the transaction described in footnote 2, FLP no longer has an indirect equity interest in RH1, and FLP does not have a direct or indirect control relationship with RH1. Therefore, FLP is no longer deemed to indirectly beneficially own the 418,294 shares of Common Stock directly beneficially owned by RH1. (continued in footnote 4)
(4) (continued from footnote 3) After the transaction described in footnote 2, LMN134 no longer has an indirect equity interest in RH1, and LMN134 does not have a direct or indirect control relationship with RH1. Therefore, LMN134 is not deemed to indirectly beneficially own the 418,294 shares of Common Stock directly beneficially owned by RH1. After the transaction described in footnote 2, Mr. Nelson no longer has an indirect equity interest in RH1, and Mr. Nelson does not have a direct or indirect control relationship with RH1. Therefore, Mr. Nelson is no longer deemed to indirectly beneficially own the 418,294 shares of Common Stock directly beneficially owned by RH1. (continued in footnote 4)
(5) (continued from footnote 4) After the transaction described in footnote 2, as a member of FLG with an approximate 33.33% equity interest in FLG, Mr. Torino may be deemed to have acquired indirect beneficial ownership of the 418,294 shares of Common Stock directly beneficially owned by FLR, and, together with the 418,294 shares of Common Stock Mr. Torino may be deemed to indirectly beneficially own through his indirect equity interest in RH1, Mr. Torino may be deemed to beneficially own 836,588 shares of Common Stock. (continued in footnote 9)
(6) (continued from footnote 5) In addition to the transaction described in footnote 2, ONIROT made an investment in FLP equal to 26.36% of the equity interest of FLP. As a result, ONIROT may be deemed to have acquired indirect beneficial ownership of the 418,294 shares of Common Stock directly beneficially owned by FLR. (continued in footnote 7)
(7) (continued from footnote 6) MJX is the designated filer. The Reporting Persons are filing this joint Form 4 because they may be regarded as part of a group. However, each Reporting Person disclaims beneficial ownership of the shares owned by the other Reporting Persons and disclaims membership in a group, and this filing shall not constitute an acknowledgement that the Reporting Persons are part of a group.
