2.1 Licensor hereby grants to Licensee the exclusive, perpetual, royalty-free, world-wide right and license to use the TECHNOLOGIES in the FIELD OF USE. Licensor retains the exclusive right to use the TECHNOLOGIES in all areas other than the FIELD OF USE. Licensor may also use the TECHNOLOGIES in its research and development activities in connection with photovoltaic materials.

2.2 All improvements to any of the TECHNOLOGIES created by Licensee or anyone acting on Licensee's behalf will belong to Licensee, provided that Licensor will be granted a non-exclusive, perpetual, royalty-free, worldwide right and license to use such improvements outside of the FIELD OF USE.

3.1 Licensor shall, at its election and expense, have the primary right, but not the obligation, to prosecute any and all claims against third parties for infringement or misappropriation of the TECHNOLOGIES. If Licensor finds it necessary or desirable, it may join the Licensee as a party in any suit or proceeding against third parties alleging infringement or misappropriation of the TECHNOLOGIES. Licensor shall also have the right, but not the obligation, to defend any and all claims by third parties alleging infringement or misappropriation of the TECHNOLOGIES. Should

Licensor elect not to prosecute or defend any claim described above, it shall promptly give notice thereof to the Licensee and the Licensee shall have the right, at its own expense, to prosecute or defend the claim.

4.1 Licensor represents and warrants to Licensee that Licensor owns the TECHNOLOGIES listed on Exhibit A and has the full power and authority to grant the license provided for in this Agreement.

4.2 Licensor represents and warrants that the license granted to Licensee hereunder does not and will not conflict with or violate the terms of any agreement between Licensor and any third party. However, certain of these inventions and trade secrets were invented pursuant to government contracts and are subject to certain government rights in connection therewith.

4.3 To Licensor's knowledge, the use of the TECHNOLOGIES listed on Exhibit A by the Licensee in the FIELD OF USE will not infringe any proprietary right of any third party and there is no claim threatened or pending against Licensor alleging that use of the TECHNOLOGIES in the FIELD OF USE will infringe the proprietary right of any other person. Except as set forth above, Licensor makes no representations or warranties with regard to infringement.

5.1 The term of this Agreement shall commence on the date first listed above and shall continue until terminated pursuant to Article 6 below.

6.1 Licensee will be deemed to be in default hereunder if Licensee breaches any material covenant made by it hereunder and fails to remedy such breach within thirty (30) days after notice thereof from Licensor.

7.1 Licensee acknowledges that in the course of the Agreement Licensor will be furnishing it with certain information ("Information") concerning the TECHNOLOGIES that is confidential in nature. Licensee agrees that the Information will be kept confidential and will not, without the prior written consent of Licensor, be disclosed in any manner whatsoever, in whole or in part, and will not be used directly or indirectly for any purpose contrary to the terms of this Agreement. Moreover, Licensee agrees to transmit the Information only to those representatives within its organization, or other individuals or companies who or which are confidentially bound to Licensee, who need to know the Information to allow Licensee to use the TECHNOLOGIES in the manner intended by this Agreement and who are informed of the confidential nature of the Information and who agree to be bound by the terms of this Agreement.

Subject to the foregoing, this Agreement may not be assigned, nor may the rights hereunder be sublicensed, by Licensee without the prior written consent of Licensor, which consent shall not be unreasonably withheld.
