4.3 The licenses granted in Sections 4.1 and 4.2 shall not include rights to use any third party information, including, without limitation, computer programs, designs, specifications, drawings, schematics or blueprints to the extent that such third party information is specifically used in or relates to the manufacture or design of products for SELLER or for third parties.

Section 6.0 Term; Termination and Assignability

6.1 This Agreement shall remain in effect until terminated in accordance with this Section 6. For the avoidance of doubt however, unless there is a Closing, this Agreement shall be null and void ab initio and have no effect.

6.2

SELLER shall have the right to terminate any or all licenses granted to BUYER under this Agreement, in whole or in part, if:

(a)

BUYER fails at any time to make any payment required herein or in the APA; or

6.4 If BUYER is acquired by a third party, thereby becoming a Subsidiary of the third party, if BUYER notifies SELLER in writing prior to said acquisition, BUYER may retain its rights hereunder so long as such acquiring third party accepts the obligations of this Agreement and unless one of the following applies (in which case the Agreement will terminate):

6.5 Except as expressly permitted herein, neither BUYER nor SELLER shall assign or sublicense any of its rights or privileges hereunder without the other party’s prior written consent (which shall not be unreasonably withheld) . Any attempted act in derogation of the foregoing shall be considered void. However, a party which undergoes reorganization may assign such rights and delegate its obligations to its legal successor, provided that after the reorganization, the successor and its Subsidiaries will have essentially the same assets as such party and its Subsidiaries had prior to the reorganization.

6.6 No failure or delay on the part of SELLER in exercising its right of termination hereunder for any one or more causes shall be construed to prejudice its right of termination for such causes or any other or subsequent causes.

6.7 Upon termination of this Agreement, all licenses granted by SELLER in Section 4 will automatically terminate, and BUYER shall promptly return to SELLER or destroy all tangible information containing SELLER’s Confidential Information or third party Confidential Information for which SELLER has responsibility, and shall promptly certify to SELLER such return or destruction which BUYER shall have possession of at such time. Notwithstanding the foregoing, BUYER shall not be obligated to return to SELLER or destroy information which has been transferred or otherwise provided to customers prior to the date of any termination of this Agreement. The confidentiality obligations of the Confidentiality Agreement will remain in effect beyond any termination for the time period stated in the Confidentiality Agreement. No

termination of this Agreement or any license granted hereunder shall relieve BUYER of any obligation or liability accrued hereunder prior to such termination. If this Agreement is terminated as a result of the exercise of SELLER’s right under Section 6.2(a) and (b), then all assignments granted by SELLER in Section 3 shall automatically revert to SELLER, and BUYER shall promptly return to SELLER or, at SELLER’s option destroy, all tangible information containing such assigned information.

Section 7.0 Representations and Warranties

7.1 SELLER represents and warrants that it has the full right and power to grant the assignments and licenses set forth in Section 3 and 4; provided however, that SELLER makes no representations or warranties with respect to any infringement of patents or other intellectual property rights of third parties other than that stated in Section 7.2.
