expiration of nine months after the Commencement Date submit written request with the items required above for disbursement or reimbursement for any reimbursable costs out of the First Contribution with respect to Space A and Space B, and to the
extent of any funds for which request has not been made prior to that date or if and to the extent that the reimbursable costs of the Tenant Work relating to Space A and Space B are less than the amount of the First Contribution, then Landlord shall
retain the unapplied or unused balance of the First Contribution and shall have no obligation or liability to Tenant with respect to such excess. Tenant must prior to the expiration of nine months after the Third Delivery Date submit written request

extent that the reimbursable costs of the Tenant Work relating to Space C are less than the amount of the Second Contribution, then Landlord shall retain the unapplied or unused balance of the Second Contribution and shall have no obligation or
liability to Tenant with respect to such excess. If the costs of completing the Tenant Work relating to (i) Space A and Space B, and (ii) Space C, respectively, exceed the First Contribution or the Second Contribution, Tenant shall pay all
such costs.”
