termination under this Section 10.3 if LICENSEE is producing and
selling Light Valve Film hereunder.  Notwithstanding the
foregoing, LICENSOR may  terminate this Agreement at any time
upon at least 30 days' notice to LICENSEE if LICENSEE shall
have failed to make any payment when due or at any time breach
any material term of this Agreement and such payment is not made
or such breach is not cured within any applicable cure period
specified in Article 11 of this Agreement, or repeatedly provide
inaccurate reports hereunder, or if there has been a cessation by
LICENSEE of general operations or of work related to Light Valve
Film.

     10.4  Effect of Termination.  If this Agreement expires or is
terminated for any reason whatsoever, in addition to any other
remedies which one party may have against the other: (1) all of
LICENSEE's rights and licenses under this Agreement shall cease,
and LICENSEE shall immediately return to LICENSOR all
Technical Information furnished to LICENSEE under this
Agreement, together with all reproductions, copies and summaries
thereof; provided, however, that LICENSEE may retain solely for
archival purposes one copy of all such documents in its legal
department files, (2) at LICENSOR's option, LICENSEE shall,
within 30 days of the date of such termination, either (A) sell and
deliver to LICENSOR under the terms specified in Section 4.2 any
Light Valve Film which shall then be in the possession of
LICENSEE, and, if requested by LICENSOR, LICENSEE shall
finish and deliver to LICENSOR any Light Valve Film in the
process of manufacture as soon as possible and, in any case, not
later than 30 days after receiving LICENSOR's request, and/or (B)
with respect to any unsold inventory and work in the process of
manufacture, to complete such work in process and sell any
remaining inventory during the period not to exceed six months
from the date of termination or expiration of this Agreement
provided that at the completion of such six-month period,
LICENSEE shall promptly destroy and dispose of any  Light Valve
Film (and Light Valve Film in the process of manufacture) not sold
under this Section 10.4 and (3) if this Agreement is terminated for
any reason on or before December 31, 2009, LICENSEE hereby
grants to LICENSOR a nonexclusive, royalty-free, irrevocable,
worldwide license with the right to grant sublicenses to others to
utilize all technical information, improvements and/or
modifications  (whether or not the subject of patents or pending
patent applications) developed or invented by or on behalf of
LICENSEE and/or its sublicensees, subcontractors, or agents
hereunder through the date of such termination of this Agreement
relating to Light Valves, Light Valve Film or SPD Emulsion which
relate to or arise out of Technical Information or materials
disclosed or provided by LICENSOR or its licensees and their
sublicensees to LICENSEE, and upon such termination,
LICENSEE shall provide LICENSOR in reasonable detail
complete information regarding such technical information,
improvements and/or modifications.  The foregoing license shall
be self-effectuating, but LICENSEE agrees upon written notice by
LICENSOR at any time hereafter to deliver to LICENSOR within
30 days of such notice any document or other instrument
reasonably requested by LICENSOR to convey such license rights
to LICENSOR such as, by way of example, confirmations or
instruments of conveyance or assignment.  No termination of this
Agreement by expiration or otherwise shall release LICENSEE or
LICENSOR from any of its continuing obligations hereunder, if
any, or limit, in any way any other remedy one party may have
against the other party.  Notwithstanding the foregoing,
LICENSEE's obligations to LICENSOR under Sections 3.1, 3.2,
4.6, 4.7, 4.8, 6.1, 6.2, 7.2, 8.5, 10.2, 10.4, 12.1, and Articles 13
and 14 shall survive any termination or expiration of this
Agreement.

11   EVENTS OF DEFAULT AND REMEDIES.

     11.1  Events of Default.  Each of the following events shall
constitute an "Event of Default" under this Agreement:

     11.1.1    (a) A party's material breach or material failure to
punctually perform any of its duties and obligations under this
Agreement, which material breach or failure, if curable, remains
uncured for thirty (30) days after written notice of such breach or
failure is received by the breaching party; or (b) a material
misrepresentation is made by a party in any representation or
warranty contained in this Agreement and the misrepresented facts
or circumstances, if curable, remain uncured thirty (30) days after
written notice of such misrepresentation is received by the
breaching party; and, in either case, if such breach or
misrepresentation is not curable, termination shall occur thirty (30)
days after such misrepresentation or breach at the option of the
non-breaching party; or

     11.1.2    The failure by a party upon request to provide the
other party with adequate assurances of its performance of all
obligations under this Agreement upon: (a) such first party's filing
of a voluntary petition in bankruptcy; (b) the filing of any
involuntary petition to have such first party declared bankrupt
which has not been dismissed within ninety (90) days of its filing;
(c) the appointment of a receiver or trustee for such first party
which has not been rescinded within ninety (90) days of the date
of such appointment; or (d) such first party otherwise becoming
insolvent or otherwise making an assignment for the benefit of
creditors.

     11.2  Default by a Party.  If there occurs an Event of Default
with respect to a party, the other party may:

     (a)  seek damages; and/or

     (b)  seek an injunction or an order for mandatory or specific
performance; and/or

     (c)  terminate this Agreement and the licenses granted to
          LICENSEE hereunder whereupon the non-defaulting
          party shall have no further obligations under this
          Agreement except those which expressly survive
          termination.

12   CONFIDENTIALITY.

     12.1  Confidential Information. (a) LICENSEE agrees for
itself, its sublicensees, and their employees and agents that for
twenty (20) years from the  later of the Effective Date of this
Agreement or the latest date of its receipt of information disclosed
to LICENSEE by LICENSOR pursuant to this Agreement, such
information shall be held in confidence; provided, however, there
shall be no obligation to treat as confidential information which is
or becomes available to the public other than through a breach of
this obligation, or which was already possessed by LICENSEE in
writing (or otherwise provable to be in the possession of
LICENSEE) prior to the Effective Date of this Agreement  (and
was not received from LICENSOR) or which is shown by
LICENSEE to have been received by it from a third party who had
the legal right to so disclose it without restrictions and without
breach of any agreement with LICENSOR or its licensees. The
burden of proving the availability of any exception of
confidentiality shall be on the LICENSEE. LICENSOR shall affix
an appropriate legend on all written documentation given to
LICENSEE which contains confidential information.    LICENSEE
acknowledges that the list of patent applications contained on
Schedule A shall be deemed to be confidential information. Other
than for the oral information conveyed during the training
conducted pursuant to Sections 8.2 and 8.3 hereof, if any, all of
which shall be deemed to be confidential information, if
confidential information is otherwise conveyed orally by
LICENSOR after training has been completed, LICENSOR shall
specify to LICENSEE at the time such information is being
conveyed (or in a subsequent letter referring to the conversation)
that the information conveyed is confidential.  It is understood and
agreed that, unless otherwise provided in a separate agreement
between LICENSEE and LICENSOR, LICENSEE has no
obligation hereunder to provide LICENSOR with any confidential
or proprietary information, and that LICENSOR shall have no
obligation hereunder to LICENSEE to maintain in confidence or
refrain from commercial or other use of any information which
LICENSOR is or becomes aware of under this Agreement.  The
terms and provisions of this Agreement or any other agreement
between the parties shall not be considered confidential, and the
parties hereto acknowledge that, pursuant to the Securities
Exchange Act of 1934, as amended, and the regulations
promulgated thereunder,  LICENSOR may file copies of this
Agreement with the Securities and Exchange Commission and
with NASDAQ and with any other stock exchange on which
LICENSOR's securities may be listed.  LICENSEE agrees that for
the period of time during which LICENSEE is obligated to keep
Technical Information confidential hereunder, LICENSEE will not
make, use, sell, lease or otherwise dispose of products using or
directly or indirectly derived from confidential information or
sample materials supplied to LICENSEE by LICENSOR or its
licensees, sublicensees, or any of their affiliates relating to Light
Valve Film, SPD Emulsion or Light Valves or which otherwise
comprise suspended particles, which when subjected to a suitable
electric or magnetic field, orient to produce a change in the optical
characteristics of the suspension ("SPD Technology") unless an
agreement between LICENSOR and LICENSEE permitting it to
do so is in full force and effect and the royalties, if any, provided
in such agreement are being paid to LICENSOR on such products.
The foregoing restriction shall not apply to products (i) which do
not directly or indirectly incorporate SPD Technology, such as, but
not limited to, liquid crystal devices, electrochromic devices, or
similar technology, or (ii) which incorporate technology involving
suspended particles, which when subjected to a suitable electric or
magnetic field, orient to produce a change in the optical
characteristics of the suspension but which is independently
developed and which is not in any way directly or indirectly
derived from any Technical Information of LICENSOR or its
licensees, sublicensees, or any of their affiliates. LICENSEE shall
have the burden of proving by clear and convincing evidence that
the availability of any exception of confidentiality exists or that the
foregoing restrictions do not apply to a particular product.
Nothing contained in this section, however, shall be construed as
granting LICENSEE any rights or licenses with respect to any
Technical Information or patents of LICENSOR or its other
licensees or their sublicensees.

     (b) LICENSEE will have the right to provide materials to, and
to disclose information of LICENSOR to a subcontractor relating
to this Agreement; provided, however, that LICENSEE shall only
disclose such information as is strictly necessary to enable said
subcontractor to perform its manufacturing task, and provided that
prior to disclosing any information to said subcontractor, said
subcontractor has signed a secrecy agreement with LICENSEE at
least as protective of LICENSOR's Technical Information as the
provisions of this Agreement, including, without limitation, said
subcontractor's specific agreement to be bound by the provisions
of Section 12.1 hereof to the same extent as LICENSEE.  For such
purposes, LICENSEE may develop a standard form of secrecy
agreement for LICENSOR's approval, after which LICENSEE
may use such secrecy agreement with all subcontractors without
LICENSOR's prior approval of the secrecy agreement being
necessary. LICENSEE shall have all subcontractors sign said
secrecy agreement prior to the disclosure of  Technical Information
to said subcontractor, and LICENSEE shall send LICENSOR a
copy of every such secrecy agreement within thirty (30) days after
the execution thereof.

warrants to the other that:

     13.1.1  Valid Agreement.  The execution and delivery of this
Agreement by the officer or representative so doing, and the
consummation of the transactions contemplated hereby, have been
duly authorized by all necessary corporate action by LICENSOR
and LICENSEE and this Agreement is a valid and binding
obligation enforceable against the parties in accordance with its
terms, except to the extent limited by bankruptcy, insolvency,
moratorium and other laws of general application relating to
general equitable principles;

     13.1.2 No Conflicts.  Nothing herein conflicts with its rights
and obligations pursuant to any agreement by a party and any other
entity; and

     13.1.3  Publicity. The parties shall have the right to use non-
confidential information, including but not limited to information
concerning this Agreement, a description of the other party, and its
logos for marketing, sales, technical assistance, investor relations,
disclosure and public relations purposes, and that information
permitted to be disclosed by a party under this Section 13.1.3 may
appear on such party's (or its subsidiaries' or sublicensees')
Internet web site, along with links to the Internet web sites, and
specific pages therefrom, of the other party and its subsidiaries and
sublicensees.

     13.2  LICENSOR Representations.  LICENSOR represents
and warrants, for the benefit of LICENSEE, that:

     13.2.1  Title.  As of the date hereof, LICENSOR represents
and warrants that  it has the right to convey the rights and licenses
granted by this Agreement, and otherwise to perform its
obligations under this Agreement. LICENSOR has caused its
employees who are employed to do research, development, or
other inventive work to disclose to it any invention or information
within the scope of this Agreement and to assign to it rights in
such inventions and information in order that LICENSEE shall
receive, by virtue of this Agreement, the licenses granted to it
under Section 2.1 hereof.

     13.2.2  Infringement.  As of the date hereof, LICENSOR is
not aware of any claim for patent infringement or the
misappropriation of trade secrets, being asserted against it by any
third party; or of any infringement of the patents listed on Schedule
A hereto by any entity.

     13.2.3 Patents in Force.  To the best of LICENSOR's
knowledge, all of the patents listed on Schedule A hereto are
currently in force.

     13.3 No Warranty.  LICENSOR and LICENSEE make no
guaranty or warranty to one another under this Agreement (a) that
LICENSEE will be able to develop, manufacture, sell or otherwise
commercialize Light Valve Film, or (b) as to the validity of any
patent.

     13.4 Representation.  LICENSOR hereby represents and
warrants that, as of the Effective Date hereof,  to the best of its
knowledge there have been no claims, actions or proceedings
brought or threatened against it or its licensees alleging that any
SPD Emulsion, Light Valve Film, and Light Valves manufactured
using Technical Information or other technical information
disclosed by LICENSOR constitutes infringement of any patent of
any third party.

14    MISCELLANEOUS.

     14.1  Applicable Law.  This Agreement shall be interpreted,
construed, governed and enforced in accordance with and
governed by the laws of the State of New York, and LICENSOR
and LICENSEE hereby submit to the exclusive jurisdiction of the
state or federal courts located in the County of Nassau and State of
New York for such purposes.  Should any dispute arise between
LICENSOR and LICENSEE in connection with this Agreement,
LICENSOR and LICENSEE shall first endeavor to settle such
dispute in an amicable manner through mutual consultation.

     14.2  Confidentiality In Court Proceeding.  In order to protect
and preserve the confidential information of a party which the
parties recognize may be exchanged pursuant to the provisions of
this Agreement, the disclosing party may request, and the receiving
party shall not oppose, the court in any action relating to this
Agreement to enter a protective order to protect information which
is confidential information under Section 12.1 and to seal the
record in the action or to hold the proceedings, or portion of the
proceedings, in camera; provided, that the requested terms do not
prejudice the receiving party's interests.  Nothing, however, shall
preclude either party from thereafter moving to unseal its own
records or to have matter and information designated as
confidential under any relevant protective order designated
otherwise in accordance with the circumstances as they shall
appear at that time.

     14.3  Severability.  If any provision of this Agreement is
declared or found to be illegal, unenforceable or void, the parties
shall negotiate in good faith to agree upon a substitute provision
that is legal and enforceable and is as nearly as possible consistent
with the intentions underlying the original provision.  If the
remainder of this Agreement is not materially affected by such
declaration or finding and is capable of substantial performance,
then the remainder shall be enforced to the extent permitted by
law.

     14.4  Waiver.  Unless agreed to by the parties in writing to the
contrary, the failure of either party to insist in any one or more
instances upon the strict performance of any one or more of the
provisions of this Agreement, or to exercise any right contained in
this Agreement or provided by law, shall not constitute or be
construed as a waiver or relinquishment of the performance of such
provision or right or the right subsequently to demand such strict
performance or exercise of such right, and the rights and
obligations of the parties shall continue unchanged and remain in
full force and effect.

     14.5  Captions.  The captions and headings in this Agreement
are inserted for convenience and reference only and in no way
define or limit the scope or content of this Agreement and shall not
affect the interpretation of its provisions.

     14.6  Assignment. This Agreement shall be binding on and
shall inure to the benefit of the parties and their successors and
assigns.  However, LICENSEE agrees that it shall not assign this
Agreement or its rights hereunder without the prior written consent
of LICENSOR except to a successor to substantially all of its
business relating to Light Valves and whose obligations hereunder
are guaranteed to LICENSOR by LICENSEE.  LICENSOR may
assign all of its rights and obligations hereunder to any successor
to any of its business interests or to any company controlling or
controlled by LICENSOR. All assignees shall expressly assume in
writing the performance of all the terms and conditions of this
Agreement to be performed by the assigning party, and an
originally signed instrument of such assumption and assignment
shall be delivered to the non-assigning party within 30 days of the
execution of such instrument.

     14.7  Schedules.  All Schedules attached to this Agreement
shall be deemed to be a part of this Agreement as if set forth fully
in this Agreement.

     14.8  Entire Agreement.  This Agreement constitutes the
entire understanding and agreement between LICENSOR and
LICENSEE with respect to the subject matter hereof, supersedes
all prior agreements, proposals, understandings, letters of intent,
negotiations and discussions with respect to the subject matter
hereof and can be modified, amended, supplemented or changed
only by an agreement in writing which makes specific reference to
this Agreement and which is executed in writing by the parties;
provided, however, that either party may unilaterally waive in
writing any provision imposing an obligation on the other.

     14.9  Notices.  Any notice required or permitted to be given
or made in this Agreement shall be in writing and shall be deemed
given on the earliest of (i) actual receipt, irrespective of method of
delivery, (ii) on the delivery day following dispatch if sent by
express mail (or similar next day courier service), or (iii) on the
