The Reporting Persons have entered into a Joint Filing Agreement, a copy of which is filed with this Schedule 13G as Exhibit 1, pursuant to which the Reporting Persons have agreed to file this Schedule 13G jointly in accordance with the provisions of Rule 13d-1(k) of the Securities Exchange Act of 1934, as amended.

Common Stock, based on (1) 214,723,023 shares of Common Stock issued and outstanding on October 3, 2011, as reported in the Form 424B3 Prospectus filed by the Issuer on October 4, 2011, plus (2) 13,000,000 shares of Common Stock issuable to Cranshire Capital Master Fund pursuant to such Securities Purchase Agreement, and (3) 333,334 shares of Common Stock issuable to the Managed Account pursuant to such Securities Purchase Agreement.

The foregoing excludes (I) 11,700,000 shares of Common Stock issuable upon exercise of a warrant to be issued to Cranshire Capital Master Fund pursuant to such Securities Purchase Agreement (the “Master Fund Warrant”) because the Master Fund Warrant contains a blocker provision under which the holder thereof does not have the right to exercise the Master Fund Warrant to the extent that such exercise would result in beneficial ownership by the holder thereof (together with the holder’s affiliates, and any other persons acting as a group together with the holder or any of the holder’s affiliates) of more than 4.99% of the Common Stock, (II) 300,001 shares of Common Stock issuable upon exercise of a warrant to be issued to the Managed Account pursuant to such Securities Purchase Agreement (the “Managed Account Warrant”) because the Managed Account Warrant contains a blocker provision under which the holder thereof does not have the right to exercise the Managed Account Warrant to the extent that such exercise would result in beneficial ownership by the holder thereof (together with the holder’s affiliates, and any other persons acting as a group together with the holder or any of the holder’s affiliates) of more than 4.99% of the Common Stock, (III) 534,698 shares of Common Stock issuable upon conversion of a convertible note held by Cranshire Capital (the “Note”) because the Note contains a blocker provision under which the holder thereof does not have the right to convert the Note to the extent (but only to the extent) that such conversion would result in beneficial ownership by the holder thereof or any of its affiliates of more than 4.9% of the Common Stock, (IV) 833,333 shares of Common Stock issuable upon exercise of a warrant held by Cranshire Capital (the “First Cranshire Warrant”) because the First Cranshire Warrant contains a blocker provision under which the holder thereof does not have the right to exercise the First Cranshire Warrant to the extent that such exercise would result in beneficial ownership by the holder thereof (together with the holder’s affiliates, and any other persons acting as a group together with the holder or any of the holder’s affiliates) of more than 4.9% of the Common Stock, (V) 794,944 shares of Common Stock issuable upon exercise of a second warrant held by Cranshire Capital (the “Second Cranshire Warrant”) because the Second Cranshire Warrant contains a blocker provision under which the holder thereof does not have the right to exercise the Second Cranshire Warrant to the extent that such exercise would result in beneficial ownership by the holder thereof (together with the holder’s affiliates, and any other persons acting as a group together with the holder or any of the holder’s affiliates) of more than 4.9% of the Common Stock, and (VI) 193,799 shares of Common Stock issuable upon exercise of a third warrant held by Cranshire Capital (the “Third Cranshire Warrant”) because the Third Cranshire Warrant contains a blocker provision under which the holder thereof does not have the right to exercise the Third Cranshire Warrant to the extent that such exercise would result in beneficial ownership by the holder thereof and the holder’s affiliates and any other persons whose beneficial ownership would be aggregated with the holder’s for purposes of Section 13(d) of the Securities Exchange Act of 1934, of more than 4.999% of the Common Stock. Without such blocker provisions, each of the Reporting Persons may be deemed to have beneficial ownership of 27,833,504 shares of Common Stock.
