Item 1.

         This Amendment No. 1 to Schedule 13D (this "Amendment No. 1") amends
and restates, where indicated, the statement on the initial Schedule 13D
relating to the Common Stock of the Issuer filed by The Quercus Trust, David
Gelbaum and Monica Chavez Gelbaum (the "Reporting Persons") with the Securities
and Exchange Commission on June 16, 2009 (the "Prior Schedule"). Capitalized
terms used in this Amendment No. 1 but not otherwise defined herein have the
meanings given to them in the Prior Schedule. Except as otherwise set forth
herein, this Amendment No. 1 does not modify any of the information previously
reported by the Reporting Persons in the Prior Schedule.

Item 5.  Interest in Securities of the Issuer

(a) As of the date of this Amendment No. 1, the Reporting Persons beneficially
own 2,817,257 shares of Common Stock. This represents a sum of (i) 660,812
shares of Common Stock and (ii) 2,156,445 shares of Common Stock underlying
currently exercisable warrants held by the Reporting Persons. As of the date
hereof, the foregoing represents a beneficial ownership of 6.9% of the shares of
Common Stock (based on 38,694,333 shares of Common Stock outstanding, as
reported on the Issuer's Form 10-Q filed with the Securities and Exchange
Commission on 11/19/2010, and after giving dilutive effect to the exercise of
the warrants of the Reporting Persons, in accordance with Rule 13D).

(b) The Reporting Persons have shared voting and dispositive power with respect
to 2,817,257 shares of Common Stock. Each of David Gelbaum and Monica Chavez
Gelbaum, acting alone, has the power to exercise voting and investment control
over shares of Common Stock beneficially owned by the Trust.

(c) On February 16, 2010, the Reporting Persons converted their 9% Convertible
Note (the "Note") into 1,260,812 shares of Common Stock, which accounts for the
conversion of the outstanding principal amount of $578,223 plus accrued and
unpaid interest, at a conversion price of $0.50 per share.

         Additionally, pursuant to that certain Purchase Agreement dated
February 11, 2010 (the "Purchase Agreement"), the Reporting Persons agreed to
sell to a private purchaser 600,000 free trading shares of common stock of the
Issuer (the "Shares"), with the Shares being delivered via DTC to the purchaser
and with the purchase price being set and paid two days after the Shares clear
DTC (as defined as being free of any restriction of any kind including by DTC,
the Issuer, the transfer agent and the Reporting Persons' brokerage and clearing
firms) and being 65% of the lowest closing bid price for the five days preceding
the date the Shares clear DTC, ending with the day the Shares clear DTC. In the
event the Shares clear DTC after the market closes, the Shares will be deemed to
clear DTC on the following market day. The sale became effective as of February
16, 2010, the date on which the Note was converted into shares of Common Stock,
but the Shares have not cleared DTC as of the date hereof. A copy of the
Purchase Agreement is attached hereto as Exhibit "B", the full text of which is
incorporated herein by this reference.

(d) Not applicable.

(e) Not applicable.

Item 6.  Contracts, Arrangements, Understandings or Relationships With
         Respect to Securities of the Issuer

         (a) Pursuant to the Power of Attorney filed as Exhibit "B" to Amendment
No. 1 to Schedule 13D filed on August 24, 2007 with respect to the issuer Emcore
Corp., David Gelbaum has been appointed as Monica Chavez Gelbaum's
Attorney-In-Fact.
