Operating Costs Tenant shall pay to Landlord the Tenant’s Percentage of Operating Costs (as hereinafter defined) incurred by Landlord in any calendar year. Tenant shall remit to Landlord, on the first day of each calendar month, estimated payments on account of Operating Costs, such monthly amounts to be sufficient to provide Landlord, by the end of the calendar year, a sum equal to the Operating Costs, as reasonably estimated by Landlord from time to time. The initial monthly estimated payments shall be in an amount equal to 1/12th of the Initial Estimate of Tenant’s Percentage of Operating Costs for the Calendar Year. If, at the expiration of the year in respect of which monthly installments of Operating Costs shall have been made as aforesaid, the total of such monthly remittances is greater than the actual Operating Costs for such year, Landlord shall promptly pay to Tenant, or credit against the next accruing payments to be made by Tenant pursuant to this subsection 4.2.3, the difference; if the total of such remittances is less than the Operating Costs for such year, Tenant shall pay the difference to Landlord within twenty (20) days from the date Landlord shall furnish to Tenant an itemized statement of the Operating Costs, prepared, allocated and computed in accordance with generally accepted accounting principles. Any reimbursement for Operating Costs due and payable by Tenant with respect to periods of less than twelve (12) months shall be equitably prorated.
