Real Estate Taxes Tenant shall pay to Landlord, as additional rent, for each tax period partially or wholly included in the term, Tenant’s Percentage of Taxes (as hereinafter defined). Tenant shall remit to Landlord, on the first day of each calendar month, estimated payments on account of Taxes, such monthly amounts to be sufficient to provide Landlord, by the time real estate tax payments are due and payable to any governmental authority responsible for collection of same, a sum equal to the Tenant’s Percentage of Taxes, as reasonably estimated by Landlord from time to time on the basis of the most recent tax data available. The initial calculation of the monthly estimated payments shall be based upon the Initial Estimate of Tenant’s Percentage of Taxes for the governmental authority’s fiscal tax period applicable to the Building (the “Tax Year”) and upon quarterly payments being due to the governmental authority on August 1, November 1, February 1 and May 1, and shall be made when the Commencement Date has been determined. If the total of such monthly remittances for any Tax Year is greater than the Tenant’s Percentage of Taxes for such Tax Year, Landlord shall promptly pay to Tenant, or credit against the next accruing payments to be made by Tenant pursuant to this subsection 4.2.1, the difference; if the total of such remittances is less than the Tenant’s Percentage of Taxes for such Tax Year, Tenant shall pay the difference to Landlord at least twenty (20) days prior to the date or dates within such Tax Year that any Taxes become due and payable to the governmental authority (but in any event no earlier than twenty (20) days following a written notice to Tenant, which notice shall set forth the manner of computation of Tenant’s Percentage of Taxes). If, after Tenant shall have made reimbursement to Landlord pursuant to this subsection 4.2.1, Landlord shall receive a refund of any portion of Taxes paid by Tenant with respect to any Tax Year during the term hereof as a result of an abatement of such Taxes by legal proceedings, settlement or otherwise (without either party having any obligation to undertake any such proceedings), Landlord shall promptly pay to Tenant, or credit against the next accruing payments to be made by Tenant pursuant to this subsection 4.2.1, the Tenant’s Percentage of the refund (less the proportional, pro rata expenses, including attorneys’ fees and appraisers’ fees, incurred in connection with obtaining any such refund), as relates to Taxes paid by Tenant to Landlord with respect to any Tax Year for which such refund is obtained. In the event this Lease shall commence, or shall end (by reason of expiration of the term or earlier termination pursuant to the provisions hereof), on any date other than the first or last day of the Tax Year, or should the Tax Year or period of assessment of real estate taxes be changed or be more or less than one (1) year, as the case may be, then the amount of Taxes which may be payable by Tenant as provided in this subsection 4.2.1 shall be appropriately apportioned and adjusted.
