(The Master Fund, Partners, Advisers, Smithwood GP and Brooks are hereinafter collectively referred to as, the “Reporting Persons.”)
 
(b)           The principal business address for each of the Reporting Persons is c/o Smithwood Advisers, L.P., 1999 Avenue of the Stars, Suite 2040, Los Angeles, CA  90067.

Item 3.
Source and Amount of Funds and Other Considerations.
 
In April 2010, the Master Fund purchased 593 Auction Preferred Shares of the Issuer (collectively, the “Shares”) in the open market. The aggregate purchase price for the Shares was $12,378,875.00.  All Shares were purchased with the Master Fund’s working capital.

Item 4.
Purpose of the Transaction.
 
The Master Fund originally purchased the Shares for investment.  The purchases were made in the ordinary course of business and were not made for the purpose of acquiring control of the Issuer.
 
The Reporting Persons intend to continue to review the Master Fund's investment in the Issuer on an ongoing basis and may engage in discussions with Issuer’s management, its Board of Directors, other stockholders of the Issuer and other relevant parties, concerning the business, operations, governance, management, and future plans of the Issuer. The Reporting Persons have reviewed Amendment No. 4 to Schedule 13D dated September 9, 2011 filed by Brigade Leveraged Capital Structures Fund Ltd. (“Brigade”).  The Reporting Persons strongly agree with Brigade’s view that in this historically low interest rate environment there are a number of attractive financing alternatives to replace the Shares that the Issuer should be exploring and that would be in the Issuer’s best interests.  The Reporting Persons also have concerns with respect to the Issuer’s performance, investment strategy, concentration of investments in financial companies and corporate governance policies and practices.  The Reporting Persons note Brigade’s stated intention to nominate one person for election to the Board by holders of Shares (voting exclusively as a class) at the Issuer's 2011 annual meeting of shareholders in an effort to seek new and more effective representation on the Board.  The Reporting Persons intend to review all information it may receive with respect to any such nominee and would consider voting in favor of such nominee.
 
Accordingly, while the Reporting Persons do not have any specific plans or proposals that would result in any of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D, the Reporting Persons may from time to time consider pursuing or proposing to the Issuer or third parties any or all of such transactions.  The Reporting Persons evaluate their investment in the Shares and purposes for holding such Shares on an ongoing basis and reserve the right to change their intentions and develop plans or proposals at any time, as they deem appropriate.
 
Item 5.
Interest in Securities of the Issuer.
 
(a)           As of the date hereof, the Master Fund is the owner of 593 Auction Preferred Shares of the Issuer. By virtue of their investment management authority, each of the other Reporting Persons may be deemed to beneficially own the Shares owned by the Master Fund.   Based on 6440 Auction Preferred Shares outstanding (as reported in the Issuer’s Certified Shareholder Report for the period ended January 31, 2011), the Reporting Persons are currently the beneficial owner of 9.2% of the Auction Preferred Shares.
