Base Rent Adjustments. Base Rent shall be increased on the annual anniversary of the first day of the first full month during the Term of this Lease (each an “Adjustment Date”) by multiplying the Base Rent payable immediately before such Adjustment Date by the Rent Adjustment Percentage and adding the resulting amount to the Base Rent payable immediately before such Adjustment Date. Base Rent, as so adjusted, shall thereafter be due as provided herein. Base Rent adjustments for any fractional calendar month shall be prorated.

Base Rent Abatement. Provided that Tenant is not then in default of the terms of the Lease, after expiration of any applicable notice and cure periods, Tenant will have no obligation to pay any Base Rent with respect to the Substitute Premises for the period for the first (1st) month of the Substitute Premises Term. Notwithstanding the foregoing, Tenant’s Share of annual Direct Expenses shall not be abated during the Substitute Premises Term.

Notwithstanding anything to the contrary contained herein and provided that Tenant faithfully performs all of the terms and conditions of the Lease, as amended by this Third Amendment, Landlord hereby agrees to abate Tenant's obligation to pay monthly Base Rent for the first ten (10) full calendar months of the Extended Term.

If any Rent payment date (including the Rent Commencement Date) falls on a day of the month other than the first day of such month or if any payment of Rent is for a period which is shorter than one month, the Rent for any fractional month shall accrue on a daily basis for the period from the date such payment is due to the end of such calendar month or to the end of the Lease Term at a rate per day which is equal to 1/365 of the applicable annual Rent. All other payments or adjustments required to be made under the terms of this Lease that require proration on a time basis shall be prorated on the same basis.
