that any such person or entity listed on Schedule B or otherwise
receiving Laminated Light Valve Film is making any improper use
of such Laminated Light Valve Film, in which case LICENSEE shall
promptly notify LICENSOR of such improper use.

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 Transportation Vehicle
Window 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 herein, including but not
limited to windows for boats and other watercraft, aircraft, space
craft and space-stations, and non-window products such as but not
limited to displays, eyewear, sunvisors, 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 Transportation Vehicle Window
Product.

"Licensed Territory " means the United States, Canada and Mexico.

"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 Film" means a film or sheet or more than one thereof
comprising a suspension of particles used or intended for use solely
in or as a Light Valve.  The Light Valve Film shall comprise either
(a) a suspension of particles dispersed throughout a continuous
liquid phase enclosed within one or more rigid or flexible solid films
or sheets, or (b) a discontinuous phase of a liquid comprising
dispersed particles, said discontinuous phase being dispersed
throughout a continuous phase of a rigid or flexible solid film or
sheet.  The Light Valve Film may also comprise one or more other
layers such as, without limitation, a film, coating or sheet or
combination thereof, which may provide the Light Valve Film with
(1) scratch resistance, (2) protection from ultraviolet radiation, (3)
reflection of infrared energy, and/or (4) electrical conductivity for
transmitting an applied electric or magnetic field to the activatable
material.

"Light Valve Transportation Vehicle Window Product" means a
Light Valve used or intended for use solely as a window (including
sunroofs and window panes which are an integral part of the internal
or external structure) integrally incorporated in a mass transportation
vehicle of a type not designed or primarily intended for military use.
The term "Light Valve  Transportation Vehicle Window Product"
shall not include a Light Valve used or intended for use as a
sunvisor, but may include Light Valves which are used or intended
for use in a non-military transportation vehicle as, or as part of, or
are laminated to, or whose surface area is primarily attached to, a
window, sunroof or windshield. The term "mass transportation
vehicle" shall mean busses, trains (including light rail trains and
monorails), used for mass transit, but shall exclude passenger cars,
recreational vehicles, trucks, mobile cranes, construction vehicles,
boats or other watercraft, aircraft, space craft and space-stations and
other types of vehicles not specifically enumerated above.

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; and (B) $100 per window. The aforementioned $100
figure specified in clause (B) above shall be adjusted upward as of
each January 1st hereafter beginning on January 1, 2004 by any
increase in the Producer Price Index for Finished Goods (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

quantities of materials related to Laminated Light Valve Film or
Licensed Products for experimental use only by LICENSEE, and
shall charge LICENSEE $750 per man/day plus the cost of any other
materials used in making such materials, plus the cost of shipping
such materials to LICENSEE.  Each invoice submitted by
LICENSOR for such service shall include detailed explanations of
the charges, and, if requested by LICENSEE, copies of receipts. The
parties acknowledge that LICENSOR has no obligation to transfer to
LICENSEE any Technical Information other than as may be
embodied in such sample materials, and that, other than sample
materials, if any, that may be supplied by LICENSOR as aforesaid,
LICENSEE will be acquiring materials from authorized suppliers
other than LICENSOR.

     8.2 Inquiries. LICENSEE and LICENSOR may also at any time
during the term of this Agreement make reasonable inquiry by
telephone, facsimile or mail to one another in regard to any
information or data furnished pursuant to this Agreement.

     8.3 Visits.  During all visits by either party to the facilities of
the other party, visitors shall comply with all reasonable rules of the
host company, and each party to this Agreement will indemnify and
hold the other party harmless from any liability, claim or loss
whatsoever (i) for any injury to, or, death of, any of its employees or
agents while such persons are present at the facility of the other
party; and (ii) for any damages to its own property or to the property
of any such employee or agent which may occur during the presence
of any such person at the facility of the other party, regardless of
how such damage occurs.

     8.4  Sole Purpose.  Any documentation or information supplied
pursuant to this Agreement by either party to the other shall be used
solely for the purposes set forth in this Agreement.

9    INTELLECTUAL PROPERTY PROTECTION
RESPONSIBILITIES.

     9.1  Proprietary Rights: Notices.  Each party shall provide
appropriate notices of patents, or other similar notice of the patent
rights of the other party on all products utilizing the patented
inventions of the other party.  Either party may add its own patent
notice to any copy or embodiment which contains its patented
inventions.

     9.2  LICENSOR Exclusive Owner.  LICENSEE hereby
acknowledges LICENSOR as purporting to be the sole and exclusive
owner of the patents and patent applications listed on Schedule A,
and that, except for the rights granted hereunder, LICENSEE shall
not have any rights or attempt to assert any ownership rights in and
to those patents and patent applications.


10   TERM AND TERMINATION.

     10.1  Term.  The term of this Agreement shall extend from the
Effective Date of this Agreement to the date of termination of this
Agreement.  Unless sooner terminated or extended, as herein
provided for below, this Agreement shall terminate upon  the
expiration of the later of (A) the last to expire of the patents now or
hereafter listed in Schedule A hereof, and (B) the expiration of the
period in which LICENSEE is obligated to maintain confidential
Technical Information of LICENSOR pursuant to Section 12.1
hereof.

     10.2  Termination by LICENSEE. LICENSEE may terminate
this Agreement effective as of December 31, 2007 or as of any
anniversary thereof by giving LICENSOR prior notice thereof unless
sooner terminated as hereinafter provided.  Such notice shall be
made in writing and shall be given between 60 and 90 days prior to
the effective date for which such termination is to be effective. If
LICENSEE decides to terminate this Agreement for any reason,
LICENSEE shall provide LICENSOR, along with the
aforementioned notice of termination, with a written report
describing the reasons for such termination. After  the expiration or
termination of this Agreement, LICENSEE shall have no right to
sell, and no obligation to manufacture and deliver, Licensed Products
or Laminated Light Valve Film to any Authorized User or to any
other party.

     10.3  Termination by LICENSOR. LICENSOR may  terminate
this Agreement at any time effective as of December 31, 2005 or as
of any anniversary thereof  upon at least 30 days' notice to
LICENSEE for any reason, provided, however, that LICENSOR
shall give LICENSEE at least one years' notice of any early
termination under this Section 10.3 if LICENSEE is producing and
selling Licensed Products 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 Licensed Products.

     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 or Laminated 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
Licensed Products or Laminated 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 Laminated Light Valve Film and
Licensed Products (and Laminated Light Valve Film 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, 2007, 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, Laminated
Light Valve Film 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 except that LICENSEE may not disclose the minimum
annual royalty payments specified in Article 3 hereof without
LICENSOR's prior written consent, 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, 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 Laminated Light Valve Film or 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
