(1)	Flag Luxury Riv, LLC ("FLR") and RH1, LLC ("RH1") each directly hold 418,294 shares of Common Stock, as reported on Forms 3 filed August 23, 2006. FX Luxury Realty, LLC ("FXLR"), as sole member of both FLR and RH1 that holds 100% of the equity of FLR and RH1, may be deemed to have beneficial ownership of the foregoing 836,588 shares of Common Stock. CKX, Inc. ("CKX") as a member of FXLR that holds 50% of the equity of FXLR, may also be deemed to have beneficial ownership of the foregoing 836,588 shares of Common Stock. CKX is filing this Form 3 because it may be regarded as part of a group. However, CKX disclaims beneficial ownership of the shares owned by the other persons and disclaims membership in a group, and this filing shall not constitute an acknowledgement that CKX is part of a group.
