(collectively, the 'DLJ Entities") and Credit Suisse First Boston LLC (now known as Credit Suisse Securities (USA) LLC), entered into a Voting Trust Agreement with Xxxxx Fargo Bank, N.A. (the "Trustee") (the "Voting Trust Agreement"), pursuant to which, among other things, the DLJ Entities deposited 7,309,291 shares of Common Stock (representing 9.9% of the outstanding shares of Common Stock as of December 31, 2006) (the "Trustee Shares") into a trust (the "Trust") created by the Voting Trust Agreement and gave the Trustee the exclusive right to vote the Trustee Shares.
