BETWEEN
RESEARCH FRONTIERS INCORPORATED
AND
SPD CONTROL SYSTEMS CORPORATION

This License Agreement ("Agreement") effective as of October 25, 2005 by and between RESEARCH FRONTIERS INCORPORATED, a Delaware corporation ("LICENSOR") and SPD CONTROL SYSTEMS CORPORATION, a New York corporation ("LICENSEE").

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 also desires to provide for hire external consulting and engineering services as well as the internal creation of products other than Licensed Products which incorporate hardware and/or software related systems; 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 electronics, including but not limited to, circuit boards, controllers, connectors and wiring, used to operate products incorporating a Light Valve, but shall not include products incorporating a Light Valve unless a separate license agreement between LICENSOR and LICENSEE or its affiliated companies specifically permitting the production of products incorporating a Light Valve is hereafter signed and becomes effective. Nothing contained herein shall permit LICENSEE to sell, lease, or otherwise dispose of a Light Valve.

"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 or combined with 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 of a liquid suspension, gel, film or other material.

The "Net Selling Price" of a Licensed Product on which royalties are payable shall be 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. 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 (other than bona fide sample and demonstration units not used in actual product installations, which shall not give rise to the payment of a royalty under Section 3.1 hereof so long as they are loaned or provided by LICENSEE to the end user at LICENSEE's direct cost of components used to make such units and no other consideration or payment is received by LICENSEE from the recipient of such sample or demonstration unit), 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 Licensed Products, 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.

During the term of this Agreement, LICENSOR hereby grants LICENSEE a non-exclusive right and license to use (a) all of the Technical Information, if any, (subject to Section 8.1 hereof), furnished by LICENSOR pursuant to this Agreement, and (b) any invention claimed in (i) any of the unexpired patents now or hereafter listed on Schedule A attached hereto or (ii) unexpired patents which issue from pending patent applications now or hereafter listed in Schedule A, and any continuations, continuations-in-part, divisions, reissues, reexaminations, or extensions thereof to make, have made, and to lease, sell, or otherwise dispose of Licensed Products in the Licensed Territory.

2.2 No Other Rights. LICENSEE agrees that, except for the specific licenses granted to it under Section 2.1 hereof for use in Licensed Products, LICENSEE has not acquired any rights or licenses under this Agreement to use Light Valves or any components thereof made by or for LICENSEE or its sublicensees pursuant to this Agreement.

2.3 Sublicenses. LICENSEE shall have the right to grant non-exclusive sublicenses to any of its wholly-owned and controlled subsidiaries, whose obligations to LICENSOR hereunder LICENSEE hereby guarantees, and which acknowledges to LICENSOR in writing that it wishes to become a sublicensee hereunder prior to doing so and agrees to be bound by the terms and conditions of this Agreement. All sublicenses shall (i) be non-exclusive, (ii) shall terminate with the termination of the rights and licenses granted to LICENSEE under Section 2.1 hereof, and be otherwise limited in accordance with the limitations and restrictions which are imposed on the rights and licenses granted to LICENSEE hereunder, (iii) contain confidentiality provisions no less protective than those contained in Section 12.1 hereof, and (iv) shall contain such other terms, conditions, and licenses as are necessary to enable LICENSEE to fulfill its obligations hereunder.

3 ROYALTY PAYMENTS, REPORTS AND RECORD- KEEPING.

3.1 Royalties and Reports on Net Sales. During the term of this Agreement, LICENSEE agrees to pay LICENSOR an earned royalty which shall be ten percent (10%) of the Net Selling Price of Licensed Products which embody, or the manufacture of which utilizes, any of the rights granted under
Section 2.1 hereof, and which are manufactured by or for LICENSEE and sold, leased, used or otherwise disposed of by or for LICENSEE or a permitted sublicensee. Payments under this Section 3.1 shall be made on a quarterly basis and made within 15 days after the end of the calendar quarter in which such Licensed Products were sold, leased, used or otherwise disposed of by or for LICENSEE or a permitted sublicensee hereunder. Each royalty payment shall be in U.S. dollars and shall be accompanied by a statement by LICENSEE showing in reasonable detail the amount of Licensed Products sold, used, leased or otherwise disposed of by or for LICENSEE and its sublicensees during the preceding quarter, any deductions taken or credits applied, and the currency exchange rate used to report sales made in currencies other than U.S. dollars. LICENSEE shall use the exchange rates for buying U.S. dollars in effect on the last day of each quarter, as specified in The New York Times. The first such statement shall cover the period from the Effective Date of this Agreement to the end of the first calendar quarter in which a Licensed Product is sold, used, leased or otherwise disposed of by or for LICENSEE or its sublicensees. If requested by LICENSOR in writing at any time hereafter, the aforementioned quarterly reports and payments may be required to be made by LICENSEE on a monthly basis rather than on a quarterly basis as aforesaid. In addition, LICENSEE shall provide LICENSOR with monthly reports of its activities involving the development of Licensed Products. LICENSEE shall also furnish to LICENSOR at the same time it becomes available to any third party, a copy of each brochure, price list, advertisement or other marketing and promotional materials prepared, published or distributed by LICENSEE or its sublicensees relating to Licensed Products. LICENSOR shall have the right, but not the obligation, to approve any use by LICENSEE of LICENSOR's name, logo, or other information about Licensed Products, and to require the correction of any inaccurate information. LICENSEE agrees that it will not discriminate against or among licensees of LICENSOR in terms of pricing, delivery terms, quality control, or other terms or conditions of sale, or the fulfillment of orders. No royalty shall be due under this Section 3.1 of this License Agreement if such product does not use any intellectual property rights of LICENSOR.

3.4 Sales, Use, Returns and other Credits. Licensed Products shall be considered as sold, leased or used and royalties shall accrue on the earlier of when such Licensed Products are billed out, or when delivered, shipped or mailed to the customer. If as a result of a price reduction or a return of Licensed Products previously sold, a credit or refund to a customer is given on part or all of the sale price of such Licensed Products, a credit shall be allowed against royalties accruing thereafter under this Agreement equal to the royalty paid on that part of the sales price so credited or refunded. In addition, if another licensee of LICENSOR (an "RFI Licensee") has paid LICENSOR a royalty on a sale of their products, and such royalty includes a royalty for the selling price of a Licensed Product (to the extent that such royalty is separately designated or identifiable as a Licensed Product supplied by LICENSEE in a sales report given to LICENSOR by such RFI Licensee and exceeds any guaranteed minimum royalty payments made by such RFI Licensee to LICENSOR) supplied by LICENSEE or its permitted sublicensees hereunder to such RFI Licensee upon which LICENSEE has already paid LICENSOR a royalty, then a credit shall be allowed against royalties accruing thereafter under this Agreement equal to the royalty paid by LICENSEE to LICENSOR on the sale of such Licensed Product to such RFI Licensee. No royalty shall be due under Section 3.1 of this License Agreement if such product does not use any intellectual property rights of LICENSOR.

3.5 Recordkeeping. LICENSEE shall keep and shall cause each sublicensee to keep for six (6) years after the date of submission of each statement supported thereby, true and accurate records, files and books of accounts that relate to Licensed Products, all data reasonably required for the full computation and verification of the Net Selling Price of Licensed Products, deductions therefrom and royalties to be paid, as well as the other information to be given in the statements herein provided for, and shall permit LICENSOR or its duly authorized representatives, upon reasonable notice, adequately to inspect the same at any time during usual business hours. LICENSOR and LICENSEE agree that an independent certified public accounting firm (selected by LICENSOR from the largest ten certified public accounting firms in the United States of America, or any country in the Licensed Territory) may audit such records, files and books of accounts to determine the accuracy of the statements given by LICENSEE pursuant to
Section 3.1 hereof. Such an audit shall be made upon reasonable advance notice to LICENSEE and during usual business hours no more frequently than annually. The cost of the audit shall be borne by LICENSOR, unless the audit shall disclose a breach by LICENSEE of any term of this Agreement, or an underpayment error in excess of two percent of the total monies paid to LICENSOR by LICENSEE during the audited period, in which case LICENSEE shall bear the full cost of such audit. LICENSEE agrees to pay LICENSOR all additional monies that are disclosed by the audit to be due and owing to LICENSOR within thirty days of the receipt of the report.

3.6 Customer Referrals. Although LICENSOR is under no obligation to do so, LICENSOR may from time to time refer customers to LICENSEE. In the event that such customer purchases, leases or rents products or services from LICENSEE other than a product used as part of an overall system using SPD Technology, LICENSEE shall include the details of such transaction in its next periodic report under Section 3.5 hereof, and shall pay LICENSOR a sales commission equal to 10% of the amount received from such customer for which a royalty under Section 3.1 hereof is not paid; provided, however, that a sales commission of 4% shall apply if the product sold does not involve a system for controlling light, heat, or glare. No such payment shall be due from LICENSEE to LICENSOR if the referred customer was already a customer of LICENSEE prior to the date of referral by LICENSOR and LICENSEE informs LICENSOR of such fact at the time that the referral by LICENSOR is made. LICENSOR agrees to provide new and existing licensees with contact information for LICENSEE, and to provide LICENSEE with information about the key personnel (to the extent that such contact information has been provided to LICENSOR) at other licensees of LICENSOR.

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

13.2 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.

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.

14.10 Bankruptcy 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.
