Item 1.

         This Amendment No. 7 to Schedule 13D (this "Amendment No. 7") amends
and restates, where indicated, the statement on Schedule 13D relating to the
common stock, par value $0.0001 per share, of the Issuer ("Common Stock"), filed
by The Quercus Trust, David Gelbaum and Monica Chavez Gelbaum (collectively, the
"Reporting Persons") with the Securities and Exchange Commission (the "SEC") on
August 31, 2007 and prior amendments thereto (collectively, the "Prior
Schedules"). Capitalized terms used in this Amendment No. 7 but not otherwise
defined herein have the meanings given to them in the Prior Schedules. Except as
otherwise set forth herein, this Amendment No. 7 does not modify any of the
information previously reported by the Reporting Persons in the Prior Schedules.

Item 5.  Interest in Securities of the Issuer

         (a) As of the date of this Amendment No. 7, the Reporting Persons own
the following securities of the Issuer:

             (i) 3,636,226 shares of Common Stock, accounting for 24.1% of the
total outstanding shares of Common Stock as reported in the Issuer's 10-Q filed
with the SEC on 8/13/09;

             (ii) Warrant to purchase up to 1,560,062 shares of Common Stock
(the "Warrant"), which contains a restriction which currently prohibits the
Reporting Persons from exercising the Warrant to the extent the Reporting
Persons would, after such exercise, be beneficial owners of in excess of 19.9%
of the total outstanding shares of Common Stock, after giving effect to such
exercise;

             (iii) Option awarded on 2/26/09 to purchase 10,000 shares of Common
Stock at an exercise price of $1.05 per share, which (x) expires on earlier of
2/26/19 or 2 months after David Gelbaum ceases to serve as a director of the
Issuer and (y) vests in twelve equal monthly installments beginning on the first
month after the award and becoming fully exercisable on 2/26/10 (the "February
Option"); and

             (iv) Option awarded on 6/24/09 to purchase 15,000 shares of Common
Stock at an exercise price of $0.60 per share, which (x) expires on earlier of
6/24/19 or 2 months after David Gelbaum ceases to serve as a director of the
Issuer and (y) vests in twelve equal monthly installments beginning on the first
month after the award and becoming fully exercisable on 6/24/10 (the "June
Option" and together with the February Option, collectively, the "Options").

             Because of the limitation on exercise of the Warrant described
above, in accordance with Rule 13D, the Reporting Persons do not beneficially
own the shares of Common Stock underlying the Warrant. Therefore, in calculating
beneficial ownership and percentage of beneficial ownership in accordance with
Rule 13D, the Reporting Persons shall be deemed beneficial owners of the sum of
(1) 3,636,226 shares of Common Stock representing 24.1% of the total outstanding
shares of Common Stock and (2) that certain number of vested shares of Common
Stock underlying the Options as of the date hereof (collectively, the "Quercus
Beneficial Ownership").

         (b) The Reporting Persons have shared voting and dispositive power with
respect to the Quercus Beneficial Ownership. Each of David Gelbaum and Monica
Chavez Gelbaum, acting alone, has the power to exercise voting and investment
control over the Quercus Beneficial Ownership.

         (c) On October 30, 2009, the Reporting Persons exercised their right to
purchase 933,334 shares of Common Stock for a total purchase price of $700,000
in connection with that certain common stock rights offering made by the Issuer,
as announced and the terms of which are described in the Issuer's Form 8-Ks
filed with the SEC on 10/2/09 and 11/2/09.

         (d) Not applicable.

         (e) Not applicable.




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

         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.
