(collectively, the "Partnerships"). As the general partner to each of the Partnerships, Farallon Partners, L.L.C. ("FPLLC") may be deemed to be the beneficial owner of the Issuer's securities held by each of the Partnerships.
(2) Effective as of January 1, 2007, Douglas M. MacMahon ("MacMahon") became a managing member of FPLLC, and as a result MacMahon may be deemed to be the beneficial owner of the Issuer's securities held by the Partnerships.
(3) All of such securities of the Issuer have been previously reported by the Partnerships and other related entities and individuals on the Form 3 and Form 4s filed on June 8, 2006 by the Partnerships and the other entities and individuals listed on such forms. There have been no transactions in such securities by any such entities or individuals since such forms were filed.
(4) MacMahon and the individuals identified in the prior Form 3 and Form 4s disclaim any beneficial ownership of any of the Issuer's securities reported or referred to herein for purposes of Rule 16a-1(a) under the Securities Exchange Act of 1934, as amended (the "'34 Act"). FPLLC disclaims any beneficial ownership of any of the Issuer's securities reported or referred to herein for purposes of Rule 16a-1(a) under the '34 Act, or otherwise, except as to securities representing FPLLC's pro rata interest in, and interest in the profits of, the Partnerships.
(5) MacMahon, together with the entities identified in footnote (1) of this Form 3 and the individuals identified in the prior Form 3 and Form 4s, may be deemed members of a group holding equity securities of the Issuer. The filing of this Form 3 shall not be deemed to be an admission that such entities and individuals are members of such group.
(6) The amount of securities shown in this row is owned directly by CS Equity II LLC, which is indirectly 100% owned by CapitalSource Inc.
