Item 3.

Source and Amount of Funds or Other Consideration

The Fund previously acquired (i) 641,031,747 shares of Common Stock; (ii) a Secured Convertible Promissory Note due July 31, 2010 and convertible into 500,000,000 shares of Common Stock; (iii) a Secured Convertible Promissory Note due November 1, 2010 and convertible into 166,666,666 shares of Common Stock (each Secured Convertible Promissory Note, a “Note” and collectively, the “Notes”); and (iv) certain Warrants to purchase in the aggregate 1,383,334 shares of Common Stock (the “Warrants”).

The terms of each of the Issuer’s Warrants held by the Fund contain a conversion cap that prevents the Fund from exercising an amount of such Warrant to the extent the Fund would beneficially own (i) greater than 4.99% of the outstanding Common Stock, and (ii) greater than 9.99% of the outstanding Common Stock. Each Warrant, however, allows the Fund to waive such conversion caps upon 61 days’ prior notice and thereby obtain the ability to exercise such Warrant without the limitation imposed by the applicable conversion cap. The Fund has not provided such notice with respect to any of the Warrants and therefore the Fund is not deemed to beneficially own any of the shares of Common Stock underlying the Warrants.

The terms of each of the Issuer’s Notes held by the Fund contain a conversion cap that prevents the Fund from converting an amount of such Note to the extent that the Fund would beneficially own (i) greater than 4.99% of the outstanding Common Stock, and (ii) greater than 9.99% of the outstanding Common Stock. Each Note, however, allows the Fund to waive such conversion caps upon 61 days’ prior notice and thereby obtain the ability to convert such Note without the limitation imposed by the applicable conversion cap. The Fund has not provided such notice with respect to any of the Notes and therefore the Fund is not deemed to beneficially own any of the shares of Common Stock underlying the Notes.

In the past 60 days, the Fund has not acquired any additional shares of Common Stock. As a result, Vicis is deemed to beneficially own 641,031,747 shares of Common Stock.

Item 4.

Purpose of Transaction.

Vicis, on behalf of the Fund, acquired the Common Stock, the Notes and the Warrants for investment purposes in the ordinary course of its business pursuant to specified investment objectives of the Fund.

In connection with a July 31, 2007 purchase by the Fund from the Issuer of a certain Senior Secured Convertible Promissory Note, the Fund acquired the right, until such time as the Fund’s fully diluted ownership of the Issuer is less than 10%, to designate one member of the Issuer’s Board of Directors, or, in the event that the number of directors on the Issuer’s Board of Directors is greater than five (5), the right to designate the number of members of the Issuer’s Board of Directors equal to the product (such product rounded up) of (x) the Fund’s fully diluted ownership of the Issuer, multiplied by (y) the total number of directors of the Issuer. The Fund designated Shad Stastney as its designee pursuant to this right, and Mr. Stastney was elected a director of the Issuer at the Issuer’s Annual Meeting of Stockholders held on June 27, 2008. Information regarding Mr. Stastney and his experience and qualifications is provided below.

Mr. Stastney is the Chief Operating Officer and Head of Research for Vicis Capital LLC, a company he jointly founded in 2004. Mr. Stastney also jointly founded Victus Capital Management LLC in 2001. From 1998 through 2001, Mr. Stastney worked with the corporate equity derivatives origination group of Credit Suisse First Boston, eventually becoming a Director and Head of the Hedging and Monetization Group, a joint venture between derivatives and equity capital markets. In 1997, he joined Credit Suisse First Boston’s then-combined convertible/equity derivative origination desk. From 1994 to 1997, he was an associate at the law firm of Cravath, Swaine and Moore in New York, in their tax and corporate groups, focusing on derivatives. He graduated from the University of North Dakota in 1990 with a B.A. in Political Theory and History, and from the Yale Law School in 1994 with a J.D. degree focusing on corporate and tax law. Mr. Stastney is currently a director of The Amacore Group, Inc., Ambient Corporation, China New Energy Group Company, and Master Silicon Carbide Industries, Inc.

On November 16, 2009, the Fund entered into a Securities Purchase Agreement (the “Securities Purchase Agreement”) with the Issuer, pursuant to which the Fund has established an escrow account into which the Fund deposited $3,000,000. Under the terms of the Securities Purchase Agreement, each time (up to a total of six times) that the Issuer certifies to the Fund that the amount of cash immediately available to the Issuer is less than $1,500,000, the Issuer becomes entitled to receive $500,000 from this escrow account and will issue to the Fund (i) 3,333,333 shares of Common Stock, and (ii) a warrant to purchase 3,333,333 shares of Common Stock at an exercise price of $0.25 and an expiration date that is two years following the date on which such warrant was issued (each such warrant, a “Series G Warrant”). Any funds remaining in this escrow account on June 30, 2011 (assuming that the Issuer and the Fund have not mutually agreed to extend the date on which this account is to be terminated to a date that is after June 30, 2011) will be returned to the Fund, and the Fund will not be entitled to receive any shares of Common Stock or any Series G Warrant with respect to such returned funds. Pursuant to the terms of the Securities Purchase Agreement, the Fund might acquire up to an additional 19,999,998 shares of Common Stock as well as Series G Warrants to purchase in the aggregate 19,999,998 shares of Common Stock. However, at this time the Fund has not acquired any such shares of Common Stock or any Series G Warrants pursuant to the Securities Purchase Agreement.

Vicis and representatives of Vicis and the Fund have had discussions with senior management of the Issuer and may in the future have such discussions concerning ways in which the Issuer could maximize shareholder value.

Except as set forth in this Item 4, Vicis has no present plan or proposal that relates to or would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D of the Act, but will continue to review this position based upon further developments.

As permitted by law, Vicis may purchase shares of Common Stock or other securities convertible, exchangeable or exercisable into Common Stock or dispose of any or all of such securities from time to time in the open market, in privately negotiated transactions, or otherwise, depending upon future evaluation of the Issuer and upon other developments, including general economic and stock market conditions.

Item 5. Interest in Securities of the Issuer

(a)

All 641,031,747 shares reported on this Schedule are held directly by Vicis Capital Master Fund, for which Vicis Capital LLC acts as investment advisor. Vicis Capital LLC may be deemed to beneficially own such 641,031,747 shares within the meaning of Rule 13d-3 of the Securities Exchange Act of 1934, as amended, by virtue of the voting and dispositive power over such shares granted by Vicis Capital Master Fund to Vicis Capital LLC. The voting and dispositive power granted to Vicis Capital LLC by Vicis Capital Master Fund may be revoked at any time.
