                                 RECITALS

     WHEREAS, LICENSOR has been engaged in research and
development in the application of physicochemical concepts to
Light Valves and Licensed Products (both as hereinafter defined)
and of methods and apparatus relating to products incorporating
such concepts; and is possessed of and can convey information
and know-how for such products and rights to manufacture, use
and sell such products; and

     WHEREAS, LICENSEE is interested in manufacturing and
selling Licensed Products; and

     WHEREAS, LICENSEE desires to acquire from
LICENSOR, and LICENSOR desires to grant to LICENSEE,
certain rights and licenses with respect to such technology of
LICENSOR;

     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 intended for use and
used as a sunshade or a special interior device as described below
(which may comprise more than one segment) attached to the
interior of a military or non-military transportation vehicle in the
manner hereinafter described, which is capable of being
controlled automatically or by the user to protect the occupant or
interior of the vehicle from sunlight or glare.  A Licensed
Product must either be (a) attached to or near the interior of a
window, windshield, back window, side window, package shelf,
sunroof or other vehicle opening in the interior of the body, or to
an accessory or component on the inside, of a military or non-
military transportation vehicle by means of a device or
mechanism, including, but not limited to, a small frame, small
rod, post or hinge mechanism, or roll up device to provide a
fixed or movable screen, (b) attached to or near the housing of a
rear-view mirror inside such transportation vehicle provided that
the sunshade so attached is not used to obstruct the mirror so as
to vary the reflectivity of such mirror, and is only used to block
sunlight or glare next to such mirror, or (c) attached to or near a
panel, roof, dashboard package shelf, door, seats, or other
window surrounding area in which a shade may be temporarily
or permanently placed for coverage of a window opening. A
Licensed Product, however, when used as a sunshade, may be
used as a special device in the interior of the vehicle which is
attached to the original window material (which may glass or
plastic), for example, as a film attached to the surface or the
window material or, incorporated between two pieces of
transparent material (which may be glass or plastic), provided
that such a special device as described above is not a Licensed
Product unless such special device is separated from the vehicle
windows and is also not within the vehicle's glass or plastic
exterior surfaces such as a window, sunroof, or glass roof
system. The term "Licensed Product" however, shall without
limitation thereto, not include (1) Light Valves which are used or
intended for use in a transportation vehicle which are installed
outside the transportation vehicle or which are laminated within
the original window (glass or plastic) material or are permanently
laminated, as a film to, the original window surface,  (2) Light
Valves which are used or intended for use as, or as part of, any
other window product and (3) Light Valves used or intended for
use as or in any non-window product such as but not limited to
displays, toys, eyewear, mirrors or filters for scientific
instruments, lamps or contrast enhancement of displays, and (4)
Light Valves used or intended for use in any product other than
as specifically defined herein.  The term "transportation vehicle"
shall include, but shall not be limited to, passenger cars,
motorcycles, recreational vehicles, trucks, mobile cranes, trains,
and boats, but shall not include aircraft, spacecraft, satellites, or
space stations. 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 Licensed
Product.

"Licensed Territory " means all countries of the world.

"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.

The "Net Selling Price" of a Licensed Product on which royalties
are payable shall be the larger 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) 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 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
sunshade associated with the incorporation of a Light Valve, and
the denominator of which is the total direct cost for such product;
and (C) $50 per square foot of sunshade. The aforementioned
$50 per square foot figure specified in clause (C) above shall be
adjusted upward as of each January 1st hereafter beginning on
January 1, 2003 by any increase in the Producer Price Index for
Motor Vehicle Parts and Accessories (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 confidential and
proprietary 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 which are 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.

notice to LICENSEE for any reason, provided, however, that
LICENSOR shall give LICENSEE at least two years' notice of
any early termination under this Section 10.3 if LICENSEE is
producing and selling Licensed Products hereunder, and
provided further that if LICENSOR gives LICENSEE a notice of
termination pursuant to the first sentence of this Section 10.3 and
the effective termination date of such notice would be prior to
the expiration of a binding contractual obligation of LICENSEE
to supply Licensed Products to a customer of LICENSEE which
contract is in effect at the time LICENSOR's termination notice
is given,  then the LICENSEE may, by providing LICENSOR
within 10 business days with a copy of the relevant portion of
such contract, extend the effective date of LICENSOR's
termination to December 31st of the calendar year in which the
aforesaid contractual obligation of LICENSEE to its customer
expires, but in no event shall the foregoing extension imply any
extension of time beyond the time period specified in Section
10.1 above.  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 Licensed Products.
[Confidential Information Omitted and filed separately with the
Securities and Exchange Commission]

     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 at
LICENSEE's direct cost of manufacture any Licensed Products
which shall then be in the possession of LICENSEE, and, if
requested by LICENSOR, LICENSEE shall finish and deliver to
LICENSOR any Licensed Products 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 Licensed
Products (and Licensed Products 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, 2005,
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 to 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 and its permitted
sublicensees, 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 receipt requested, postage prepaid and addressed as

an involuntary petition shall be filed against such party, the
parties intend that the non-filing party shall be protected in the
continued enjoyment of its rights hereunder to the maximum
feasible extent 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.

     14.11  Construction.  This Agreement and the exhibits
hereto have been drafted jointly by the parties and in the event of
any ambiguities in the language hereof, there shall no be
inference drawn in favor or against either party.

     14.12  Counterparts.  This Agreement may be executed in
