We have offices in Boston, Massachusetts, and Redwood City, California. Our principal executive offices are located at 131 Dartmouth Street, 3rd Floor, Boston, Massachusetts. On January 31, 2024, our Boston, Massachusetts lease at 200 Berkeley Street was terminated by the landlord due to closing of the office space. On January 19, 2024, we entered into a membership agreement with Industrious Bos 131 Dartmouth Street LLC for office space at 131 Dartmouth Street, Boston, Massachusetts (the Dartmouth Street Agreement). The Dartmouth Street Agreement commenced on February 1, 2024 and was set to originally expire on January 31, 2025. On March 12, 2024 and on November 25, 2024, we amended the Dartmouth Street Agreement to include additional office space and extend the term of the lease. As amended on November 25, 2024, the extended lease commenced on February 1, 2025 and will expire on January 31, 2026.

We also lease office and laboratory space located at 1000 Bridge Parkway, Redwood City, California. The lease commenced on March 31, 2020 and expires on February 28, 2030. In addition, we lease office space at 1200 Bridge Parkway, Redwood City, California. This lease commenced on June 17, 2022 and will expire on June 30, 2025.

We believe that our office and laboratory space is sufficient to meet our current needs and that suitable additional space will be available as and when needed.
