CCRC, LLC is the general partner of CCRC, L.P., and, as such, has the power to vote or direct the vote and to dispose or direct the disposition of all Shares held by CCRC, L.P. MSDWCI IV, L.P. is the sole member of CCRA, LLC, and, as such, has the power to direct the actions of CCRA, LLC. Therefore, CCRC, LLC and MSDWCI IV, L.P. each may be deemed to have beneficial ownership of the 31,372 Shares deemed to be beneficially owned by CCRC, L.P. MSDWCP IV, LLC is the general partner of MSDWCP IV, L.P., MSDW IV 892, L.P. and MSDWCI IV, L.P. (collectively, "Funds IV") and, as such, has the power to direct the actions of Funds IV.
