The term of the New Lease commences on the Effective Date and ends on the 13th anniversary of the Rent Commencement Date, described below. The Company has the option to extend the term of the New Lease for two additional consecutive five year terms.

The Base Rent will be fixed at approximately $148,000 per month and will increase by approximately 2.0% per annum. The Company will also be obligated to pay to the Landlord certain costs, taxes and operating expenses related with the New Lease and the Premises, subject to certain exclusions. The Landlord will provide the Company with an improvement allowance of up to approximately $2.3 million in the aggregate for costs relating to the design, permitting, and construction of improvements to the Premise. The New Lease provides for a rent abatement of $1.4 million, applied in equal monthly amounts, during the first year of the term of the New Lease such that the monthly Base Rent will be approximately $2,500.
The Landlord has the right to terminate the New Lease upon customary events of default. The Company may also terminate the New Lease effective as of April 30, 2030 so long as the Company gives notice no later than April 30, 2029 and pays a Termination Fee of approximately $2.9 million concurrent with such notice.
