Tenant may exercise the right to extend the Building #3 Lease Term for a New Renewal Term only by delivering to Landlord written notice of Tenant’s exercise of such right no less than three (3) months prior to the expiration date of the Building #3 Lease Term or the first New Renewal Term, if applicable, time being of the essence. The terms and conditions of the Building #3 Lease Term shall continue in full force and effect for each New Renewal Term and the monthly rental for each New Renewal Term, if applicable, shall continue at the same rental of $38,692.23.
