As used herein, "Converted Allowance Cap" shall mean One Hundred Fifteen Thousand One Hundred Forty Dollars ($115,140.00). Tenant shall have no right to, and Landlord shall have no obligation to fund, any 2-3 Tenant Improvement Allowance not properly requisitioned by Tenant on or before the first (1st) anniversary of the 2-3 Extended Term Commencement Date or applied towards Base Rent in accordance with this Section 2(f).
