Estate Taxes shown in such bill within thirty (30) days following receipt of such notice and bill from Landlord or fifteen (15) days prior to the date that such taxes will become delinquent, whichever is later. Landlord shall take the benefit of any statute or ordinance permitting Real Estate Taxes to be paid in installments, and the payments required hereunder shall be made in such installments. Landlord shall be responsible for any interest or penalty resulting from Landlord’s delay in billing Tenant or Landlord’s delay in paying Real Estate Taxes to the taxing authority; Tenant shall be responsible for any interest or penalty resulting from Tenant’s failure to make payment of Real Estate Taxes to Landlord or the applicable taxing authority as the case may be in accordance with the deadlines for payment set forth in this Section 5.1.

5.2 Tenant shall have the right to contest the amount or validity, in whole or in part, of any Real Estate Taxes, or to seek a reduction in the valuation of the Property, or any part thereof, as assessed for Real Estate Tax purposes, by appropriate proceedings diligently conducted in good faith; provided that, Tenant must either pay any such taxes in protest, submit such bonds to the taxing authorities or take such other action as may be prudent to prevent any loss or forfeit of the Property or any penalties. Landlord shall cooperate with any such tax reduction proceeding at Tenant’s sole cost and expense. Landlord shall notify Tenant of any increase in the assessed valuation of the Property at least thirty (30) days before the last day for filing an objection thereto. Any refund of Real Estate Taxes that were paid by the Tenant during the Term or for a period allocable to the Term shall promptly be paid to and be the property of Tenant. Tenant agrees to indemnify, defend and hold Landlord harmless from and against any claims, liabilities, damages, loss, expenses, costs to, or penalties incurred by, Landlord arising from Tenant’s contesting any Real Estate Tax or seeking a reduction in the valuation of the Property pursuant to this Section 5.2.

5.3 Real Estate Taxes shall be apportioned between Landlord and Tenant for tax bills relating to the Term, so that Tenant shall be required to pay only the portion of the Real Estate Taxes allocable to the Premises during the Term (including the Extension Period, if applicable), and Landlord shall pay the remainder of such Real Estate Taxes.

5.4 Anything in this Section 5 to the contrary notwithstanding, Tenant shall have no obligation to pay Real Estate Taxes which Landlord has failed to bill to Tenant for one year or more following the date such Real Estate Taxes were due and payable.
