     NOW, THEREFORE, in consideration of the premises and
the mutual covenants herein and for other good and valuable
consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties agree as follows.

1    DEFINITIONS.

        The following terms when used herein shall have the
respective meanings set forth in this Article 1.

The "Effective Date" of this Agreement shall be the date which is
the last date of formal execution of this Agreement by duly
authorized representatives of the parties to this Agreement as
indicated on the signature page of this Agreement.

"Licensed Product" means a Light Valve Aircraft Window
Shading Product, incorporating a Light Valve.  The term
"Licensed Product" shall not include Light Valves used or
intended for use in any product other than as specifically defined
herein, such as other window products not specifically defined
hereinabove, windows for other transportation vehicles, including,
but not limited to passenger cars, trains, monorails, recreational
vehicles, trucks, mobile cranes, boats, vans, sport utility vehicles,
space craft and space-stations, and non-window products such as
but not limited to displays, eyewear, sun visors, toys, mirrors or
filters for scientific instruments, lamps or contrast enhancement of
displays.  The term "display" means any device for displaying
letters, numbers, images or other indicia or patterns.  Nothing
contained herein shall permit LICENSEE to sell, lease, or
otherwise dispose of a Light Valve which is not combined or
intended to be combined as described above into a Light Valve
Aircraft Window Shading Product.

"Licensed Territory " means all countries of the world except
North and South Korea.

"Light Valve" means a variable light transmission device
comprising: a cell including cell walls, containing or adapted to
contain an activatable material, described hereinafter, such that a
change in the optical characteristics of the activatable material
affects the characteristics of light absorbed by, transmitted through
and/or reflected from the cell; means incorporated in or on the cell,
or separate therefrom for applying an electric or magnetic field to
the activatable material within the cell; and coatings, (including,
but not limited to, electrodes), spacers, seals, electrical and/or
electronic components, and other elements incorporated in or on
the cell.  The activatable material, which the cell contains or is
adapted to contain, includes in it solid suspended particles, which
when subjected to a suitable electric or magnetic field, orient to
produce a change in the optical characteristics of the device, and
may be in the form a liquid suspension, gel, film or other material.

"Light Valve Aircraft Window Shading Product" means a Light
Valve used or intended for use solely as a window, shade, or cabin
divider, integrally incorporated in, or attached as a fixture to the
external structure or internal structure of an airplane, helicopter, or
jet aircraft.

The "Net Selling Price" of a Licensed Product on which royalties
are payable shall be the greatest  of the following: (A) the genuine
selling price of LICENSEE and its sublicensees hereunder
(including amounts charged for any wiring, installation, and
related services provided by LICENSEE and its sublicensees
hereunder, but not including structural materials used in the
aircraft sidewall assembly that are not used or related to the
window or shade component of an aircraft sidewall) f.o.b. factory
at which nonaffiliated customers are billed in the usual course of
business for a Licensed Product, as packed for shipment to the
customer; (B) the genuine selling price of LICENSEE and its
sublicensees hereunder (including amounts charged for any wiring,
installation, and related services provided by LICENSEE and its
sublicensees hereunder) f.o.b. factory at which nonaffiliated
customers are billed in the usual course of business for the overall
product which incorporates a Licensed Product, as packed for
shipment to the customer, multiplied by a fraction, the numerator
of which is the direct cost of all components included in the
window or cabin divider associated with the incorporation of a
Light Valve, and the denominator of which is the total direct cost
for such overall product; and (C) $100 per Licensed Product. The
aforementioned $100 figure specified in clause (C) above shall be
adjusted upward as of each January 1st hereafter beginning on
January 1, 2002 by any increase in the Producer Price Index for
Aircraft Parts and Equipment-NEC (the "Index") for the 12 month
period ending in December of the prior year, prepared by the
Bureau of Labor Statistics of the United States Department of
Labor (or if the Index is not then being published, the most nearly
comparable successor index).  In calculating a genuine selling
price of a product for the above calculation, such price may be
reduced only by the applicable proportions of the following if, and
to the extent that, amounts in respect thereof are reflected in such
selling price: (i) normal trade discounts actually allowed; (ii) sales,
use or excise and added value taxes and custom duties paid; (iii)
if the genuine selling price is other than f.o.b. factory, amounts
paid for f.o.b. transportation of the product to the customer's
premises or place of installation or delivery; (iv) insurance costs
and the costs of packing material, boxes, cartons and crates
required for shipping; provided, however, that for purposes of this
calculation, the genuine selling price of a product may not be less
than 90% of the gross selling price of said product after all
deductions therefrom, if any.  If a product is leased, sold, used or
otherwise disposed of on terms not involving a bona fide arm's
length sale to an unaffiliated third party, then the Net Selling Price
for such transactions shall be deemed to be the Net Selling Price
as defined above for identical products sold to a nonaffiliated
customer nearest to the date of such lease, sale, use, or other
disposition.

"Technical Information" means all useful information relating to
apparatus, methods, processes, practices, formulas, techniques,
procedures, patterns, ingredients, designs and the like including
(by way of example) drawings, written recitations of data,
specifications, parts, lists, assembly procedures, operating and
maintenance manuals, test and other technical reports, know-how
of LICENSOR, and the like owned or controlled by LICENSOR,
to the extent they exist, that relate to Light Valves, Licensed
Products and/or to the suspensions or other components used or
usable for Licensed Products or Light Valves including, but not
limited to, particles, particle precursors, coatings, polymers, liquid
suspensions and suspending liquids, or any combination thereof,
and that consist of concepts invented or developed by LICENSOR.
Know-how of LICENSOR's suppliers and of LICENSOR's other
licensees and their sublicensees under licenses from LICENSOR
shall not be considered Technical Information owned or controlled
by LICENSOR.

terminated for any reason on or before December 31, 2004,
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, or Licensed Products, 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, 3.5, 4.2, 4.3, 4.4, 4.5, 4.6, 6.1, 6.2,
7.2, 8.3, 8.4, 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 failure to make any payment due in a
timely manner or 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, and except with respect to royalty payments
          due and owing to LICENSOR as of the termination date
          or any subsequent period specified in Section 10.4.

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.
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 is confidential information
of LICENSOR. If confidential information is otherwise conveyed
orally by LICENSOR, 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 information confidential
hereunder, LICENSEE will not make, use, sell, lease or otherwise
dispose of products using or directly or indirectly derived from
Licensed Products, Light Valves, or Components, 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, or
electrochromic devices, 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 provide materials to, and
to disclose information, 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.

13   WARRANTIES AND REPRESENTATIONS.

     13.1  Reciprocal Representations.  Each party represents and
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, 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 Licensed Products, or (b) as to the validity of any
patent.

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.

     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
sixth day after mailing by registered or certified air mail, return

including, without limitation, if it so elects, the protection
conferred upon licensees under section 365(n) of Title 17 of the
U.S. Code.  Each party agrees that it will give the other party
immediate notice of the filing of any voluntary or involuntary
petition under the federal bankruptcy laws.
