The aforementioned $100 figure specified in clause (B) above shall be adjusted upward as of each January 1st hereafter beginning on January 1, 2010 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.

References to "Sections" and to "Schedules" shall be to the sections and schedules of this Agreement except where expressly stated otherwise.

"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.

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 LICENSEE repeatedly provides inaccurate reports hereunder, or if there has been a cessation by LICENSEE of general operations or of work related to Licensed Products, and "cessation" shall not include any temporary cessation of operations or work by LICENSEE as may occur from time to time.

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 or destroy the same (except for any which is incorporated into samples which have been supplied to a customer of LICENSEE as permitted hereunder), together with all reproductions, copies and summaries thereof (insofar as it is possible to do so); 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 or expiration, 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 60 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 or expires, upon such termination or expiration, 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 or expiration of this Agreement relating to Light Valves, or Licensed Products (excluding any technology that does not relate directly to the creation of variable light transmission in an SPD window, including but not limited to: infrared reflective coatings, antennas, heating grids, interlayer, glass fabrication technology, glass compositions, glazing systems technology, including encapsulation, structural enhancements, sealants, and adhesives) and upon such termination or expiration, 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. LICENSEE may exclude from such license any improvements to lamination or components, and processing know-how developed by or on behalf of LICENSEE but only to the extent that LICENSEE or any third party has not filed for patent protection on such items and maintains them as trade secrets. 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 (only until the end of the month in which the last of all sales under this Agreement occurs), 3.5, 3.6, 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 March 25, 2004 (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, but the failure to so affix such legend shall not affect the confidential nature of such 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 (subject to the terms of Section 13.1.3 and unless LICENSEE has informed LICENSOR on a non-confidential basis of the nature of such information beforehand and LICENSOR has agreed in writing to receive such information from LICENSEE which LICENSEE wishes to be considered confidential, in which case it shall be kept confidential for no more than a period of three years from the date of disclosure unless another period of confidentiality is otherwise agreed to by LICENSOR and LICENSEE at the time of disclosure). 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 knowingly make, use, sell, lease or otherwise dispose of products using or directly or indirectly derived from Licensed Products, Light Valves, or Components (other than where all obligations of confidentiality in respect of such confidential information or sample materials as are so provided to LICENSEE from LICENSOR or its licensees and their sublicensees and so made, used, sold, leased or otherwise disposed of by LICENSEE or its sublicensees have validly terminated other than through a breach by LICENSEE or any third party of any obligation of confidentiality), 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 agrees to make all reasonable and careful enquiries to determine whether any SPD Technology is derived in any way from Technical Information or patents of the LICENSOR. 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 (which is not in the public domain other than through a breach by LICENSEE or any third party of any obligation of confidentiality) 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 of LICENSEE or to a customer of LICENSEE or subcontractor of such customer (each of the foregoing being referred to as a "Recipient") relating to this Agreement; provided, however, that LICENSEE shall only disclose such information as is strictly necessary to enable said Recipient to perform its manufacturing task, and shall ensure that prior to disclosing any information to said Recipient, said Recipient 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 Recipient'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 Recipients without LICENSOR's prior approval of the secrecy agreement being necessary. LICENSEE shall have all Recipients sign said secrecy agreement prior to the disclosure of Technical Information to said Recipient, 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, a description of the other party, and its logos (to the extent permitted by Section 5.1 or otherwise pursuant to the consent of the other party, which consent may not be unreasonably withheld or delayed) 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.

13.4 Disclosure In the event that after the date of this Agreement either party becomes aware of any fact or matter which renders any of the warranties and representations set out at this Section 13 untrue, it shall promptly notify the other party of the same, without prejudice to any rights and remedies of such other party for any breach of any such warranty or representation, provided that this Section 13.4 shall not impose any additional obligations on a party other than the obligation of disclosure set forth herein.

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.
