Item 4.     Ownership.

Reference is hereby made to Items 5-9 and 11 of pages 2, 3, 4 and 5 of this Schedule, which Items are incorporated by reference herein.

Steelhead Navigator is the beneficial owner of: (i) convertible debentures (the “Convertible Notes”) which, as of December 31, 2011, were convertible into 11,191,559 shares of the issuer’s common stock; and (ii) warrants (“Warrants”) to purchase up to 8,588,260 shares of the issuer’s common stock (subject to the Ownership Limitations described below).  A certain other client account for which Steelhead acts as investment manager is the beneficial owner of 180,000 shares of the issuer’s common stock. 

The exercise of the Warrants are subject to restrictions (the “Ownership Limitations”) that prohibit exercise to the extent that, after giving effect to such exercise, the holder of the Warrants (together with such holder’s affiliates) would, as a result of such exercise, beneficially own in excess of 9.9% of the total number of issued and outstanding shares of the issuer’s common stock (including for such purposes the shares of the issuer’s common stock issued upon such exercise). 

Based on 294,771,836 shares of common stock of the issuer outstanding as of October 28, 2011, as indicated in the issuer’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on November 9, 2011, Steelhead Navigator has the right (consistent with the Ownership Limitations), as of December 31, 2011, to acquire up to 19,779,819 shares of the issuer’s common stock through the conversion of the Convertible Notes and/or exercise of the Warrants. 

The securities reported on this Schedule as beneficially owned by Steelhead (the “Securities”) are held by and for the benefit of Steelhead Navigator and a certain client account. Steelhead, as the investment manager of Steelhead Navigator and such client account, and the sole member of Steelhead Navigator’s general partner, and each of J. Michael Johnston and Brian K. Klein, as the member-managers of Steelhead, may be deemed to beneficially own the Securities held by Steelhead Navigator and such client account for the purposes of Rule 13d-3 under the Securities Exchange Act of 1934 (the “Act”), insofar as they may be deemed to have the power to direct the voting or disposition of those Securities. 

Neither the filing of this Schedule nor any of its contents shall be deemed to constitute an admission that any of Steelhead, Mr. Johnston or Mr. Klein is, for any other purpose, the beneficial owner of any of the Securities, and each of Steelhead, Mr. Johnston and Mr. Klein disclaims beneficial ownership as to the Securities, except to the extent of his or its pecuniary interests therein.

Under the definition of “beneficial ownership” in Rule 13d-3 under the Act, it is also possible that the individual general partners, executive officers, and members of the foregoing entities might be deemed the “beneficial owners” of some or all of the Securities insofar as they may be deemed to share the power to direct the voting or disposition of such Securities.  Neither the filing of this Schedule nor any of its contents shall be deemed to constitute an admission that any of such individuals is, for any purpose, the beneficial owner of any of the Securities, and such beneficial ownership is expressly disclaimed.

The calculation of percentage of beneficial ownership in Item 11 of pages 2, 3, 4 and 5 of this Schedule was derived from the issuer’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on November 9, 2011, in which the issuer stated that the number of shares of its voting common stock outstanding as of October 28, 2011 was 294,771,836 shares.

Item 5.     Ownership of Five Percent or Less of a Class.

Not applicable.

Item 6.     Ownership of More Than Five Percent on Behalf of Another Person.

Not applicable.

Item 7.     Identification and Classification of the Subsidiary Which Acquired the Security Being Reported on By the Parent Holding Company or Control Person.

Not applicable.

Item 8.     Identification and Classification of Members of the Group.

Not applicable.
