The Company has operating leases for office and lab space in South San Francisco, California and office space in San Diego, California.

The lease amendment includes the option to extend the lease for one additional year. In October 2021, the Company entered into a lease amendment for the current San Diego facility that extended the lease expiration from December 2021 to February 2022. Additionally, in September 2021, the Company entered into a lease agreement for a new San Diego facility with a term of 36 months that is expected to commence in February 2022.
