(1) See Item 5(a) of this Amendment No. 9 for a more detailed explanation of the
beneficial ownership and percentage of beneficial ownership of the Reporting
Persons with respect to the shares of Common Stock of the Issuer.



CUSIP No. 29268T102

Item 1.

         This Amendment No. 9 to Schedule 13D (this "Amendment No. 9") 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. 9 but not otherwise
defined herein have the meanings given to them in the Prior Schedules. Except as
otherwise set forth herein, this Amendment No. 9 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. 9, the Reporting Persons own
the following securities of the Issuer:

                  (i) 4,636,226 shares of Common Stock. .

                  (ii) Option (right to buy) 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 the earlier of 2/26/19 or 12 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"). As of the date of this Amendment No. 9, 9,167 shares of
         Common Stock underlying the February Option have vested and may be
         deemed to be beneficially owned by the Reporting Persons.

                  (iii) Option (right to buy) granted 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 the earlier of 6/24/19 or 12 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"). As
         of the date of this Amendment No. 9, 8,750 shares of Common Stock
         underlying the June Option have vested and may be deemed to be
         beneficially owned by the Reporting Persons.

                  (iv) Warrant to purchase up to 1,560,062 shares of Common
         Stock at an exercise price of $0.01 per share (the "2008 Warrant"),
         which contains a restriction prohibiting the Reporting Persons from
         exercising the 2008 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.

                  (v) Right to receive a warrant to purchase up to 150,000
         shares of Common Stock at an exercise price of $0.01 per share (the
         "2009 Warrant"). The 2009 Warrant is subject to approval by the
         Issuer's shareholders at the next shareholders meeting and as a result
         may not be deemed to be beneficially owned by the Reporting Persons as
         of the date of this Amendment No. 9.

                  Because of the limitation on exercise of the 2008 Warrant and
shareholder approval required for the 2009 Warrant described above, in
accordance with Rule 13D, none of the Reporting Persons are deemed to
beneficially own the shares of Common Stock underlying the 2008 Warrant and the
2009 Warrant. Therefore, in calculating beneficial ownership and percentage of
beneficial ownership in accordance with Rule 13D, the Reporting Persons may be
deemed beneficial owners of approximately 4,654,143 shares of Common Stock
representing 21.9% of the total outstanding shares of Common Stock as of the
date of this Amendment No. 9, which are derived from a sum of (1) 4,636,226
shares of Common Stock and (2) 17,917 vested shares of Common Stock underlying
the Options (collectively, the "Quercus Beneficial Ownership").



CUSIP No. 29268T102


         (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) Pursuant to that certain Stock Purchase Agreement dated December
30, 2009 (the "SPA"), the Reporting Persons agreed to purchase from Diker
Management LLC ("Diker") in two installments a total of 1,000,000 shares of
Common Stock. On December 31, 2009, as part of the first installment, the
Reporting Persons purchased 375,000 shares of Common Stock for a purchase price
of $0.80 per share. On February 19, 2010, as part of the second installment, the
Reporting Persons purchased 625,000 shares of Common Stock for a purchase price
of $0.95 per share. A copy of the SPA is attached hereto as Exhibit "B" and 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

                                   ARTICLE II
                  REPRESENTATIONS AND WARRANTIES OF THE SELLER

     The Seller represents and warrants to the Purchaser as set forth below.

2.1 LEGAL CAPACITY AND AUTHORITY.

         The Seller is an entity duly organized and validly existing under the
laws of the jurisdiction of its formation. The Seller has all requisite power
and authority to execute, deliver and perform its obligations under this
Agreement. This Agreement has been duly and validly authorized, executed and
delivered on behalf of the Seller and shall constitute the legal, valid and
binding obligation of the Seller enforceable against it in accordance with its
terms, except as such enforceability may be limited by general principles of
equity or to applicable bankruptcy, insolvency, reorganization, moratorium,
liquidation and other similar laws relating to, or affecting generally, the
enforcement of applicable creditors' rights and remedies.

2.2 TITLE TO PURCHASED SHARES.

         The Seller is the sole record and beneficial owner of the Purchased
Shares to be sold by it pursuant to this Agreement and owns the Purchased Shares
free from all taxes, liens, claims, encumbrances charges, security interests,
pledges, escrows, lock-up arrangements ("CLAIMS"). There are no outstanding
rights, options, subscriptions or other agreements or commitments (oral or
written) obligating the Seller to sell or transfer the Purchased Shares and the
Purchased Shares are not subject to any lock-up or other restriction on their
transfer or on the ability of the Purchaser to sell or transfer the Purchased
Shares. Delivery to the Purchaser of the Purchased Shares purchased by the
Purchaser will convey, free and clear of all Claims, any and all rights and
benefits incident to the ownership of the Purchased Shares.

2.3 ACCREDITED INVESTOR STATUS.

         The Seller is an "accredited investor" as that term is defined in Rule
501(a) of Regulation D under the Securities Act.

2.4 NONCONTRAVENTION.

         The execution, delivery and performance by the Seller of this Agreement
and the consummation by the Seller of the transactions contemplated hereby will
not (a) result in a violation of the organizational documents of the Seller, (b)
conflict with, or constitute a default (or an event which with notice or lapse
of time or both would become a default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, any agreement,
indenture or instrument to which the Seller is a party, or (c) result in a
violation of any law, rule,





regulation, order, judgment or decree (including federal and state securities
laws) applicable to the Seller, except in the case of clause (b) and (e) above,

6.1 GOVERNING LAW; JURISDICTION; JURY TRIAL.

         All questions concerning the construction, validity, enforcement and
interpretation of this Agreement shall be governed by the internal laws of the
State of New York, without giving effect to any choice of law or conflict of law
provision or rule (whether of the State of New York or any other jurisdictions)
that would cause the application of the laws of any jurisdictions other than the
State of New York. Each party hereby irrevocably submits to the exclusive
jurisdiction of the state and federal courts sitting in The City of New York,
Borough of Manhattan for the adjudication of any dispute hereunder or in
connection herewith or with any transaction contemplated hereby or discussed
herein, and hereby irrevocably waives, and agrees not to assert in any suit,
action or proceeding, any claim that it is not personally subject to the
jurisdiction of any such court, that such suit, action or proceeding is brought
in an inconvenient forum or that the venue of such suit, action or proceeding is
improper. Each party hereby irrevocably waives personal service of process and
consents to process being served in any such





suit, action or proceeding by mailing a copy thereof to such party at the

6.3 SEVERABILITY.

         If any provision of this Agreement is prohibited by law or otherwise
determined to be invalid or unenforceable by a court of competent jurisdiction,
the provision that would otherwise be prohibited, invalid or unenforceable shall
be deemed amended to apply to the broadest extent that it would be valid and
enforceable, and the invalidity or unenforceability of such provision shall not
affect the validity of the remaining provisions of this Agreement so long as
this Agreement as so modified continues to express, without material change, the
original intentions of the parties as to the subject matter hereof and the
prohibited nature, invalidity or unenforceability of the provision(s) in
question does not substantially impair the respective expectations or reciprocal
obligations of the parties or the practical realization of the benefits that
would otherwise be conferred upon the parties. The parties will endeavor in good
faith negotiations to replace the prohibited, invalid or unenforceable
provision(s) with a valid provision(s), the effect of which comes as close as
possible to that of the prohibited, invalid or unenforceable provision(s).

with respect to the matters covered herein and therein and, except as
specifically set forth herein or therein, none of the parties hereto makes any
representation, warranty, covenant or undertaking with respect to such matters.

writing signed by the parties hereto. No provision hereof may be waived other
than by an instrument in writing signed by the party against whom enforcement is
sought.

execution and shall be binding upon the signatory thereto with the same force
and effect as if the signature were an original, not a facsimile signature.

written consent of the other, to not disclose, and to otherwise keep
confidential, the sale of the Purchased Note contemplated hereby, except to the
