7. Lease Agreements

The Company leases one facility in Emeryville, California under an operating lease that expires in February 2023. The Emeryville lease contains an option to early terminate the lease by notifying the landlord on or before February 1, 2020, which expired unexercised. The lease also contains an option to extend the lease for an additional term, however, the Company is not reasonably certain to exercise this option.

On December 18, 2019, the Company entered into a Lease Termination Agreement with each of the 7^th Street Properties II (“7^th Street LP”) and 7^th Street Property General Partnership (“7^th Street GP”) to early terminate the Company’s two operating leases in Berkeley, California.
