4.3 Grant Under Patent Rights. Effective on the Closing Date, Purchaser hereby grants to Seller, under the Patent Rights (as defined in Exhibit B hereto), and for the lives thereof, a royalty-free, irrevocable, non-exclusive, non-transferable (except as permitted under Section 4.3 below), worldwide right and license (the “Seller License”) to practice the methods and to make, have made, use, distribute, lease, sell, offer for sale, import, export, develop and otherwise dispose of and exploit any products, processes or services covered by the Patent Rights (“Covered Products”). This Seller License shall also apply to the reproduction and subsequent distribution of Covered Products, in substantially identical form as they are distributed by the Seller, by authorized agents of the Seller such as a distributor, replicator, VAR or OEM.

4.4 Limitation on Transferability. The Seller License in Section 4.3 above may be transferred one time to a purchaser of all, or substantially all, of Seller’s operating assets (other than cash) which are covered by the Seller License, or to a party that by merger or otherwise, acquires all, or substantially all, of Seller’s outstanding capital stock (any such transaction referred to as the “Acquisition” and any such purchaser or acquiring party referred to as the “Assignee”). In the event of such Acquisition, the Seller License shall automatically become limited to the Covered Products of (1) Seller that are either under development or that are commercially released on the effective date of such Acquisition and (2) Assignee that are commercially released as of the effective date of the Acquisition and, for each of (1) and (2) any new versions that have merely incremental differences from Seller’s and Assignee’s Covered Products covered by the Seller License on the effective date of the Acquisition (all such products, processes and services referred to collectively as the “Covered Items”). In no event, however, shall the Seller License be construed or interpreted to include any other products, processes or services of the Seller, Assignee or any other third party. The Seller License with respect to the Covered Items shall automatically terminate upon any subsequent Acquisition by any third party (“Subsequent Acquisition”), provided that the Seller License shall continue in full force and effect with respect to any commercially

released Covered Items of Seller or Assignee that are in inventory or are in production on the effective date of any Subsequent Acquisition. Seller or Assignee shall provide Purchaser written notice within one hundred and twenty (120) days of the Seller License being transferred under this Section 4.4 and specifically detail the Covered Items as of the effective date of the Acquisition. If Purchaser is not so notified of such transfer of the Seller License within one hundred and twenty (120) days of the effective date of Acquisition, the Seller License under Section 4.3 shall automatically terminate.

5. ADDITIONAL OBLIGATIONS

5.1 Further Assurances. At the reasonable request of Purchaser and without demanding further consideration from Purchaser, Seller agrees to execute and deliver such other instruments and do and perform such other acts and things as may be reasonably necessary for effecting completely the consummation of the transfer of ownership in and to the Patents as contemplated hereby, including without limitation execution, acknowledgment and recordation of other such papers, and using all reasonable best efforts to obtain the same from the respective inventors, as necessary or desirable for fully perfecting and conveying unto Purchaser the benefit of the transfer of ownership in and to the Patents as contemplated hereby.

5.2 Further Assistance. Subject to the terms and conditions hereof, Seller agrees, upon the reasonable request of Purchaser, to do all things necessary, proper, or advisable, including without limitation the execution, acknowledgment and recordation of specific assignments, oaths, declarations and other documents on a country-by-country basis, to assist Purchaser in obtaining, perfecting, sustaining, and/or enforcing the Patent Rights.
