Following expiration (unless earlier terminated), the rights granted to AbbVie in the AbbVie Development Agreement will continue on a non-exclusive, fully paid-up, royalty-free, perpetual and irrevocable basis. The AbbVie Development Agreement may be terminated early by either party for material breach or bankruptcy. In addition, AbbVie may terminate the AbbVie Development Agreement at any time immediately upon written notice to CollPlant if AbbVie reasonably believes that it is not advisable for AbbVie to continue to develop or commercialize the Exclusive Products under the AbbVie Development Agreement as a result of a perceived serious safety issue regarding the use of any Exclusive Product or upon 60 days’ written notice, for any or no reason, with respect to its rights under the AbbVie Development Agreement on an Exclusive Product-by-Exclusive Product or country-by-country basis.
