Operating Lease Obligations

In July 2016, we entered into a five-year lease agreement for our current headquarters facility located in Foster City, California. The original term of the lease was from September 1, 2016 to August 31, 2021, with two 30-month renewal options. In July 2019, we leased another facility in Foster City, California as a result of growth in personnel and lab space requirements. The original term of this lease was from July 1, 2019 to October 31, 2021, with no renewal options. In November 2020, we extended the terms of both of these leases for six months to March 1, 2022 and April 30, 2022, respectively. In February 2022, we entered into an early termination agreement for one of the facilities in Foster City and terminated our lease on February 12, 2022 instead of April 30, 2022.

In January 2021, we entered into a lease agreement for our new corporate headquarters facility in San Carlos, California and a license agreement for temporary lab and office space in Palo Alto, California. The lease term for our new corporate headquarters facility expires December 31, 2025. We have two 60-month renewal options. The original term of the license agreement for the temporary space in Palo Alto terminated when the San Carlos office leasehold improvements were completed and we moved into our new corporate headquarters. We extended the license agreement for the Palo Alto office by 60 days to March 3, 2022 to accommodate

our relocation plan. These two leases are accounted for as a combined lease because the contracts were negotiated as a package with the same commercial objective.
