CURIS INC

Our headquarters consist of office and laboratory space in Lexington, Massachusetts. We occupy approximately 31,112 feet of space under a lease agreement, which we entered into in December 2019 and which was amended in January 2022. A portion of the Company’s leased space is subject to an early termination option that becomes effective on the lease commencement date of a new lease for larger premises within the landlord’s commercial real estate portfolio, or the New Lease, and the Company may exercise its early termination option by providing the landlord with written notice of such election to terminate the lease agreement concurrently with the execution of the New Lease. The landlord has the option to early terminate the lease agreement by providing written notice to the Company by June 30, 2024. We believe this office and laboratory space will be sufficient to meet our needs for the foreseeable future and that suitable additional space will be available as and when needed.
