Item 3. Source and Amount of Funds or Other Consideration
          The aggregate funds expended to purchase 250,000 shares of Preferred Stock (the “Shares”) was $250,000,000 (the “Purchase Price”).

          The funding for this transaction came primarily from investors who were investors in existing funds managed by Matlin Advisers, namely, MatlinPatterson Global Opportunities Partners III L.P. (“Global”) and MatlinPatterson Global Opportunities Partners (Cayman) III L.P. (“Global Cayman”). The Thrift Fund used these funds to purchase a 100% interest in MP Thrift, and MP Thrift, in turn, used the funds to consummate the transaction.
Item 4. Purpose of Transaction
     On December 17, 2008, MP Thrift entered into an agreement, a copy of which is incorporated as Exhibit I to this Schedule 13D (the “Investment Agreement”), with the Issuer to acquire, for the Purchase Price, the Shares (the “Transaction”). MP Thrift, MPGOP, MPGOP (Cayman), MP LLC, MPAM, and MPT previously obtained the approval of the Office of Thrift Supervision (“OTS”) to acquire control of the Issuer and its savings bank subsidiary and, as a result, to become savings and loan holding companies, pursuant to Section 10(e) of the Home Owners’ Loan Act, as amended, and 12 C.F.R. Section 574.3(a).
     In connection with the closing of the Transaction, MP Thrift and the Issuer entered into a waiver and amendment agreement on January 30, 2009. Pursuant to the terms of the Investment Agreement, on January 30, 2009, MP Thrift consummated the Transaction and gained control of the Thrift.
     Pursuant to the Investment Agreement, the Issuer has agreed to seek shareholder approval to (i) amend its articles of incorporation to authorize additional common stock (ii) to amend its articles of incorporation and bylaws to eliminate classified board provisions and the applicability of the Michigan control share acquisition statute and other anti-takeover provisions and (iii) to make certain changes to the Issuer’s equity compensation plans to implement an equity incentive program (the “Proposals”). If the Proposals are approved by the Issuer’s stockholders, the Shares held by MP Thrift would automatically convert into Common Stock.
     Subject to applicable law and regulation and depending upon certain factors, including, without limitation, the financial performance of the Issuer, the availability and price of the Shares or other securities related to the Issuer, and other general market investment conditions, the Reporting Persons may determine to pursue various strategic alternatives in respect of their investments in the Issuer. Such actions may include, without limitation, direct or indirect participation in the following:
    Forming and conducting potential strategic developments and plans related to the Issuer;
 
    Restructuring and effecting other significant transactions with respect to the Issuer;
 
    Taking any other actions that could have the purpose or effect of directly or indirectly changing or influencing control of the Issuer;

Subject to applicable law and regulation such transactions may take place at any time and without prior notice. There can be no assurance, however, that the possible courses of action expressed in the immediately preceding sentence will be pursued or, if pursued, will be consummated by any, or all, of the Reporting Persons.
Item 5. Interests in Securities of the Issuer
          Each share of the Preferred Stock was sold to MP Thrift at a purchase price of $1,000 per share and is convertible into common stock of the Issuer at a rate equal to the liquidation preference divided by $0.80. No shares were acquired from the Issuer’s common shareholders. As a result of the Transaction, MP Thrift owns approximately 77.6% of the Issuer’s fully diluted outstanding equity and indirectly controls the Thrift. Upon consummation of the Transaction, the Issuer contributed approximately $225,000,000 to the Thrift, and retained approximately $25,000,000 to cover interest payments on (1) currently outstanding debt and (2) preferred stock anticipated to be issued to the U.S. Department of the Treasury pursuant to the TARP Capital Purchase Program.
          As a condition to closing the Transaction, the Issuer issued and sold to certain members of management shares of its common stock for an aggregate purchase price of approximately $5.32 million. The largest participants in this management investment were Thomas Hammond and Mark Hammond, who each invested $2 million.
          Under the Investment Agreement, as amended on January 30, 2009, MP Thrift has an obligation to fund an additional $100 million investment, subject to the completion of customary documentation by MP Thrift and the Issuer. According to the terms of this additional investment (the “Additional Capital”): (1) no later than February 13, 2009, MP Thrift will deliver $25,000,000 to the Issuer and the Issuer will issue and deliver to MP Thrift 25,000 shares of preferred stock with terms substantially identical to the Preferred Stock issued in the transaction described in this Schedule; (2) at any time following the purchase described in (1), upon two weeks prior notice by the Issuer to MP Thrift (to be delivered no later than February 27, 2009), MP Thrift will deliver $25,000,000 to the Issuer and the Issuer will issue and deliver to MP Thrift 25,000 shares of preferred stock with terms substantially identical to the Preferred Stock issued in the transaction described in this Schedule; and (3) at any time following the purchases described in (1) and (2), upon two weeks prior notice by the Issuer to MP Thrift (to be

delivered no later than March 13, 2009), MP Thrift will deliver $50,000,000 to the Issuer and the Issuer will issue and deliver to MP Thrift shares of trust preferred stock with an aggregate liquidation preference of $50,000,000 and a dividend rate of 10%, and convertible, in whole or in part, into Common Stock (of the Issuer) at the option of MP Thrift on April 1, 2010 at a conversion price equal to 90% of the volume-weighted average price per share during the period from February 1, 2009 to April 1, 2010, subject to a minimum of $0.80 and a maximum of $2.00; MP Thrift’s conversion right shall lapse if not exercised on April 1, 2010, and such shares shall be redeemable by the Issuer at any time after January 30, 2011.
          As of January 30, 2009, MP Thrift was the direct owner of 250,000 shares of Preferred Stock and 250,000 shares of Preferred Stock were outstanding as of January 30, 2009. Each share of Preferred Stock is convertible into such number of shares of common stock of the Issuer equal to the $1,000 divided by the applicable conversion price, plus cash in lieu of fractional shares. As of January 30, 2009, the applicable conversion price for each share of Convertible Participating Voting Preferred Stock Series B is $0.80 per share, so that the Reporting Persons beneficially own 77.6% of shares of common stock of the Issuer then outstanding, assuming due authorization of the Common Stock.
          MPGOP (Cayman) holds approximately 23.0% of the ownership interests of MP Thrift and MPGOP (Cayman) holds the remaining approximately 77.0% of the ownership interests in MP Thrift.
          Except as set forth in this Schedule 13D, none of the Reporting Persons has engaged in any transaction during the past 60 days involving the securities of the Issuer.
          Other than the Reporting Persons, no other person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the securities of the Issuer referred to in this Item 5.
Item 6. Contracts, Arrangements or Understandings with Respect to Securities of the Issuer
          On December 17, 2008, MP Thrift entered into the Investment Agreement with the Issuer, pursuant to which MP Thrift acquired on January 30, 2009, the Shares in exchange for the Purchase Price. Customary representations and warranties were made by the Issuer to MP Thrift relating to the Issuer, its business and the issuance of the Shares.
          Pursuant to the terms of the Investment Agreement, the Issuer has caused three board members designated by MP Thrift to be elected and appointed to its board of directors as of January 30, 2009. The Issuer has granted MP Thrift certain registration rights, including demand, piggyback and “shelf” registration rights with respect to the Shares purchased by MP Thrift under the Investment Agreement. Information in Item 5 relating to the pending Additional Capital transactions is incorporated by reference into this Item 6.
          The foregoing references to and description of the Investment Agreement and the transactions contemplated thereby do not purport to be complete and are subject to, and are qualified in their entirety by reference to, the full text of the Investment Agreement, which is incorporated by reference to this Item 6.
