LICENSE AGREEMENT

This License Agreement (“Agreement”) is made this 21st day of November, 2006, between the UD Technology Corporation, a non-profit corporation located at 15 Innovation Way, Suite 103, Newark, Delaware, 19711 (hereinafter referred to as “Licensor”) and Ascent Solar Technologies, Inc., a Delaware corporation with its principal place of business in Littleton, Colorado (hereinafter referred to as “Licensee”).

WITNESSETH THAT:

WHEREAS, Licensor is the owner of certain intellectual property related to a means of manufacturing solar cells, modules and arrays based on CuInGaSe2 and related materials encompassing 1) a multi-source physical vapor deposition process to form the CuInGaSe2 on a continuously moving substrate, 2) a method to coat a substrate with a metal that eliminates cracking and poor adhesion of the CuInGaSe2 layer, and 3) a process to deposit a CdS layer, all useful for production of photovoltaic conversion cells, modules, and arrays.

WHEREAS, Licensee desires to obtain a non-exclusive license to practice the intellectual property to make, use, and sell products comprising solar cells, modules, and/or arrays which can be prepared using the intellectual property; and

WHEREAS, Licensor is willing to grant such a license on the terms and subject to the conditions set forth below, and Licensee desires to receive and operate commercially under such a license.

NOW THEREFORE, in consideration of the premises and mutual agreements

hereinafter set forth, Licensor and Licensee agree as follows:

ARTICLE 1. DEFINITIONS

For the purpose of this License Agreement, unless the context clearly or necessarily indicates otherwise, the following words and phrases shall have the meanings set forth below:

1.1 “Licensed Patents” means all (i) patent(s) and patent application(s) listed in Exhibit A attached hereto; (ii) any international counterparts thereof; (iii) any divisionals, continuations, continuations-in-part, and extensions of any of the foregoing patents and patent application(s); (iv) all substitutions, reissues, renewals, reexaminations, patents of addition, and inventors’ certificates thereof, patent term extensions, supplementary protection certificates, and data package exclusivity extensions of the foregoing patents; and (v) all patent(s) issuing from any of the foregoing.

1.2 “Licensed Products” shall mean any solar cell, module, and/or array constituting an apparatus or article for the generation of electricity, characterized by a power rating in watts determined under standard conditions, which but for the grant of rights in Paragraph 2.1 would infringe the Licensed Patents.

1.3 “Sale” or “Sales” shall mean any bona fide transaction for which consideration is received or expected for the sale, use, lease, transfer, or other disposition of the Licensed Product(s). A Sale of Licensed Product(s) shall be deemed completed at the time that Licensee receives payment for such Licensed Products. In determining the amount of Sales, Licensee may first deduct applicable returns and allowances, as well as charges for freight, handling, transportation, in-transit insurance, sales taxes, use taxes and other applicable taxes

paid by Licensee with respect to the sale, use, lease, transfer or other disposition of Licensed Products (“Net Sales”).

1.4 “License Year” means the one year period starting on January 1, of one year and ending on December 31, of the same year. The first License Year shall begin on the Effective Date and end on December 31, 2006.

1.5 “Effective Date” means the date when this Agreement is fully executed by the parties.

1.6 “Affiliate” of a party means any corporation or other legal entity directly or indirectly controlling, controlled by or under common control of such party. For purposes, hereof, the term “controlled” (including the terms “controlled by” and “under common control with”), as used with respect to any entity, shall mean the direct and indirect ability or power to direct or cause the direction of management policies of such entity or otherwise direct the affairs of such entity, whether through ownership of equity participation, voting securities, beneficial interest, by contract or otherwise.

ARTICLE 2. LICENSE GRANT

2.1 Licensor hereby grants to Licensee for the term of this Agreement a non-exclusive, non-transferable license, without the right to sublicense except to Affiliates, under the Licensed Patents, to make, have made, use, and sell Licensed Products throughout the world.

2.2 The right to sublicense to Affiliates granted to Licensee hereunder is subject to the following conditions.

a. In each sublicense, the sublicensee shall be subject to the terms and conditions of the license granted to Licensee hereunder.

b. Each sublicense shall expressly provide that Licensor makes no warranties or representations regarding the Licensed Patents, and shall provide that Licensor has no liability to sublicensees with regard to the Licensed Patents.

c. Licensee shall forward to Licensor, within thirty (30) days of execution, the name and address of each sublicensee and the identity of any designated representative of the sublicensee (name, title, location) to receive communications relative to the sublicense and copies of each sublicense agreement upon written request of Licensor.

2.3. The rights and licenses granted to Licensee herein shall be effective as of the Effective Date.

2.4 Licensee shall use reasonable commercial efforts to develop for commercial use and to practice the Licensed Patents as soon as reasonably possible, consistent with sound and reasonable business practices.

ARTICLE 3. CONSIDERATION

3.1 In consideration for the grant of rights provided above in Paragraph 2.1, Licensee shall pay to Licensor a royalty based upon the Net Sales of Licensed Products sold or transferred according the following schedule:

[*]

3.2 Minimum royalties per License Year shall be [*] regardless of Net Sales, except that the minimum annual royalty for the first calendar year ending December 31, 2006 shall be prorated from the Effective Date. Should Licensee fail to meet any License Year’s annual minimum royalty, Licensor, in its sole discretion, may terminate this License Agreement.

3.3 The royalty due shall be paid to Licensor in United States Dollars. For

converting royalties into United States Dollars any royalties that accrue in a foreign currency, the parties shall use the average of the closing buying rates of the Morgan Guaranty Trust Company of New York applicable to transactions under exchange regulations for the particular currency on the first business day of each month of the License Year for which royalties are payable.

3.4 The royalty shall be paid annually by Licensee (on behalf of itself and its sublicensees) no later than thirty (30) days after the end of each License Year. The royalty relating to any Sales by Licensee to Affiliates shall be calculated based upon the transfers of Licensed Product and the royalty schedule provided in Paragraph 3.1, above.

3.5 Licensee’s obligation to pay royalties (for itself and its Affiliates) shall continue until the earlier of termination of this License Agreement or the date of the last to expire of the Licensed Patents. Licensee shall notify Licensor of the date of first commercial sale of Licensed Product within each country in which sales are made within (60) days of the date of such first sale.

3.6 Royalty payments shall be payable to “UD Technology Corporation” and sent to:

15 Innovation Way, Suite 103
Newark, Delaware 19711

ARTICLE 4. REPORTING BY LICENSEE

against Licensor, its licensees, or the customers of each.

ARTICLE 7. [INTENTIONALLY LEFT BLANK]
