(a) From and after the Effective Date through the last day of the tenth (10th)Lease Year, the annual Fixed Rent for (i)the Land Leased Premises shall be calculated based on the market value of Six Hundred Eighty Five Dollars ($685.00) per acre of Leased Premises, per annum, fixed for ten (10)years, as such acreage is determined by Lessor, and (ii)the Office Leased Premises shall be calculated based on a rate of $5.00 per square foot per year, or $92,875 per year, as well as $3,000 per year related to the use of Building 1 (clockhouse), (together, the Fixed Rent), payable in advance in annual installments on the first day of each January during the Term in accordance with Section4.3 hereof. From and after the tenth (10th)Lease Year through the end of the Term, the Fixed Rent during each Lease Year (as previously increased by all prior CPI Escalation) shall be increased by the CPI Escalation. Fixed Rent (and all other monthly or other periodic fixed costs, expenses or charges payable under this Land Lease) shall be prorated for partial calendar months or years. In the event that Lessee disagrees with Lessors calculation of acreage for the Leased Premises, Lessee may, at its sole cost and expense, obtain a certified survey prepared in accordance with ALTA standards, and a title insurance policy issued by a reputable national title insurance company certifying such acreage of the Leased Premises. If the amount of acreage determined as set forth herein, differs from Lessors calculations, the Fixed Rent will be adjusted for future Lease Years, but there will be no retroactive adjustment of Fixed Rent.
