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

Acquisition by any third party (Subsequent Acquisition), provided that the Seller License shall continue in full force and effect with respect to any commercially
