ITEM 4. PURPOSE OF TRANSACTION. Item 4 of the Original 13D, as heretofore amended, is being amended to include the following: On February 19, 2008, after considering the issue for more than two months, the Company informed the Investment Manager that it would be willing to nominate only one of the Investment Manager's three nominees to the board of directors of the Company (the "Board"). The Investment Manager immediately advised the Company's Board representative that this would not provide sufficient change in the composition of the Board and, on February 25, 2008, sent a letter to the Company advising that the Investment Manager had no alternative but to take its nominees directly to the Company's shareholders and to proceed with a proxy contest to elect all three of its nominees to the Board. A copy of the letter is attached hereto as Exhibit A and is incorporated by reference. ITEM 7. MATERIAL TO BE FILED AS EXHIBITS Exhibit A.
