Base Rent . Section 3.1 of the Original Lease is hereby amended to provide that Monthly Base Rent shall be as follows: (i) for the period from September 1, 2011 through August 31, 2012 (subject to the one-month rate abatement for the month of September 2011 discussed below), Monthly Base Rent shall be payable in the amount of Forty Three Thousand Four Hundred Sixty Three and Dollars ($43,463.00) per month and (ii) for the period from September 1, 2012 and each one-year anniversary thereafter (each, a “Lease Anniversary Date”) during the Term of the Lease, Monthly Base Rent shall be increased on each Lease Anniversary Date to an amount equal to one hundred three percent (103%) of the Monthly Base Rent payable in the immediately preceding month.
