Cellectis has also guaranteed the lease agreement for our headquarters. Cellectis’ guarantee of our obligations under the lease will terminate at the end of the second consecutive calendar year in which our tangible net worth exceeds $300 million. TALEN^® is our primary gene editing technology, and it is the foundation of our technology platform.

We obtained an exclusive license for the TALEN^® technology for commercial use in plants from Cellectis. We also license other technology from Cellectis. We owe Cellectis royalties on any revenue we generate from sales of products less certain amounts as defined in the license agreement, as well as a percentage of any sublicense revenues. We have incurred nominal license and royalty fees for the three months ended March 31, 2021 and March 31, 2020.
