Item 3.  Source and Amount of Funds or Other Consideration

           The source of funds for the purchase reported in this Statement was the working capital of Master Account and Capital Partners (100).

Item 4.  Purpose of Transaction

           All of the shares of Common Stock and the securities exercisable for shares of Common Stock reported on the Schedule 13D and this Statement as having been acquired for the accounts of the Reporting Persons on the Schedule 13D and this Statement were acquired for investment purposes.

          The following summary of the Purchase Agreement, the Warrants (as defined below) and the Registration Rights Agreement (as defined below) is not a complete description and is qualified in its entirety by reference to the full text of the Purchase Agreement, the Registration Rights Agreement and the Form of Stock Purchase Warrant, each of which are incorporated herein by reference to Exhibits 2, 3 and 4 hereof, respectively.

           On March 8, 2007, Master Account and Capital Partners (100) entered into the Purchase Agreement for the Issuer’s private placement of 21,415,447 newly issued shares of Common Stock at a price of $1.96 per share and the concurrent issuance of warrants to purchase an aggregate of 9,636,950 additional shares of Common Stock at an exercise price of $1.96 per share (the “Private Placement”). On March 13, 2007, Master Account and Capital Partners (100) purchased 2,219,242 and 256,005 shares of Common Stock, respectively, and consummated the transactions contemplated by the Purchase Agreement.

          Concurrently with the purchase of the shares of Common Stock, Master Account and Capital Partners (100) each entered into a Common Stock Purchase Warrant (each, a “Warrant” and together, the “Warrants”) with the Issuer for the purchase of 998,659 and 115,202 shares of Common Stock, respectively, issuable upon exercise of the Warrants. The purchase price for each Warrant was $0.125 and each Warrant is immediately exercisable and has a term of five years. The Issuer, Master Account and Capital Partners (100) agreed to waive the application of Section 2(d) of each Warrant.

          Pursuant to the Purchase Agreement, and as more specifically provided therein, Master Account and Capital Partners (100) each have the right to participate in future capital raising transactions undertaken by the Issuer within 15 months after March 13, 2007.

          In connection with the Private Placement, on March 8, 2007, Master Account and Capital Partners (100) became party to a registration rights agreement with the Issuer (the “Registration Rights Agreement”). Pursuant to the Registration Rights Agreement, the Issuer has agreed to file a registration statement by May 15, 2007 (the “Initial Registration Statement”) for purposes of registering the shares of Common Stock and the shares of Common Stock underlying the warrants issued in the Private Placement, including the Warrants (the “Warrant Shares”). To the extent any shares of Common Stock or Warrant Shares cannot be included in the Initial Registration Statement, the Issuer has agreed to file one or more subsequent registration statements (each, a “Registration Statement”) registering those shares of Common Stock or Warrant Shares not included in the Initial Registration Statement. Pursuant to the Registration Rights Agreement, MHR also has the right to receive certain liquidated damages in cash if the Initial Registration Statement is not declared effective by July 15, 2007 and/or all of the shares of Common Stock and Warrant Shares are not registered by March 31, 2008. In addition to the registration rights described above, MHR has certain piggyback registration rights covering the securities acquired in the Private Placement.

          Except as otherwise set forth in this Statement, none of the Reporting Persons currently has additional plans or proposals which relate to or which would result in any of the actions or transactions described in paragraphs (a) through (j) of Item 4 of the instructions to Schedule 13D. However, from time to time the Reporting Persons may evaluate the possibility of disposing of or acquiring shares of Common Stock, or entering into various corporate transactions involving the Issuer. The Reporting Persons reserve the right to formulate plans or proposals regarding the Issuer or any of its securities and to carry out any of the actions or transactions described in paragraphs (a) through (j) of Item 4 of the instructions to this Schedule 13D, to the extent deemed advisable by the Reporting Persons.

          From time to time each of the Reporting Persons may lend portfolio securities to brokers, banks or other financial institutions. These loans typically obligate the borrower to return the securities, or an equal amount of securities of the same class, to the lender and typically provide that the borrower is entitled to exercise voting rights and retain dividends during the term of the loan. From time to time, to the extent permitted by applicable law, each of the Reporting Persons may borrow securities, including the shares of Common Stock, for the purpose of effecting, and may effect, short sale transactions, and may purchase securities for the purpose of closing out short sale positions in such securities.
