Notwithstanding anything to the contrary, as between Sublandlord and Subtenant, the parties hereto agree that the reference to the rate of the Allowance of Fifteen Dollars ($15.00) per square foot of rentable area in the Workletter is modified to the rate established by the preceding sentence of this Section.

The Over-Allowance Amount shall be disbursed by Landlord following the disbursement of any then remaining portion of the Tenant Improvements Allowance, and such disbursement shall be pursuant to the same procedure as the Tenant Improvements Allowance. The remaining fifty percent (50%) of the Over-Allowance Amount shall be paid by Tenant to Landlord once the Tenant Improvements Allowance is expended (i.e. prior to Landlord’s use of the first installment of the Over-Allowance Amount). In the event that, after the applicable Cost Proposal Delivery Date, any revisions, changes, or substitutions shall be made to the Construction Documents or the Tenant Improvements, then, subject to Section 5.4 below, to the extent that the amount of the Cost Proposal plus any additional costs which arise in connection with such revisions, changes or substitutions or any other additional costs exceeds the sum of the Tenant Improvements Allowance and any Over-Allowance Amounts previously funded by Tenant, such excess costs shall be paid by Tenant to Landlord immediately upon Landlord’s request as an addition to the Over-Allowance Amount (whether or not the Tenant Improvements Allowance has then been fully used). Unless otherwise agreed by the parties, all Tenant Improvements paid for by the Over-Allowance Amount shall be deemed Landlord’s property under the terms of the Lease. Tenant hereby acknowledges and agrees that Tenant shall be responsible for all costs associated with the Tenant Improvements to the extent the same exceed the Tenant Improvements Allowance (notwithstanding the content of the Cost Proposal).

Payment of Costs. Tenant shall pay for the Tenant Improvements, except for the Allowance which Landlord shall advance as hereinafter provided. Landlord shall only be responsible for payment of up to the amount of the Allowance for the Tenant Improvements. If the Construction Costs for the Tenant Improvements are greater than the amount of the Allowance, Tenant shall be solely responsible for such additional costs. As provided in the definition of the Allowance, if funds of the Allowance are still available, Tenant must use up to $250,000.00 out of the Allowance for payment of FF&E acquired and installed in the Leased Premises.
