user: Read the legal provision and list the applicable contract clause categories. Provision: Notwithstanding anything to the contrary contained in this Lease, if, within one (1) year after receipt of a Statement by Tenant, Tenant (i) reasonably disputes any amounts set forth in any Statement described above in this Article 4 , (ii) Tenant has paid such disputed amounts to Landlord (although Tenant may pay such amounts “under protest”), and (iii) an Option Nullification Default has not occurred and be continuing, then Tenant shall have the right to cause Landlord’s general ledger of accounts with respect to such disputed Statement only to be audited by a nationally recognized firm of certified public accountants reasonably approved by Landlord, at no cost or expense to Landlord, which has prior experience in the review of financial statements and which shall not have provided primary accounting services to Tenant or any other tenant in the Project within the immediately preceding three (3) year period and which shall not be retained by Tenant on a contingency fee basis; provided, however, Tenant shall not have the right to perform any such audit more than one (1) time for any Expense Year during the Lease Term. Any audit conducted by or on behalf of Tenant shall be completed in a diligent manner and timely manner (but in any event within two (2) months after Tenant initially disputes the applicable Statement) and shall be performed at Landlord’s office during Landlord’s normal business hours and in a manner so as to minimize interference with Landlord’s business operations. Landlord shall have no obligation to make photocopies of any of Landlord’s ledgers, invoices or other items; provided, however, Tenant may, within the Building, make copies of such ledgers, invoices or other items; provided further, however, if Landlord is unable to make a copier machine available to Tenant for such copies, then Tenant may take such ledgers, invoices or other items to the Premises in order to make such copies. Tenant agrees to keep, and to cause Tenant’s accountant and its employees to keep, all information revealed by any audit of Landlord’s books and records strictly confidential and not to disclose any such information or permit any such information to be disclosed to anyone other than Landlord, unless compelled to do so by a court of law, and Tenant and its accountant and their employees shall sign a confidentiality agreement reflecting such confidentiality. Tenant’s audit shall be limited to an on-site review of Landlord’s general ledger of accounts and supporting documentation. If after such audit, Landlord and Tenant dispute the results of such audit, at Tenant’s request, a certified public accounting firm selected by Landlord, and reasonably approved by Tenant, shall, at Tenant’s cost, conduct an audit of the relevant Direct Expenses. The amounts payable under this Section 4.6 by Landlord to Tenant or by Tenant to Landlord, as the case may be, will be appropriately adjusted on the basis of such audit. If such audit discloses an overstatement of Direct Expenses in excess of four percent (4%) for such Expense Year, Landlord shall reimburse Tenant for all of the overcharges plus the reasonable cost of both audits within thirty (30) days after completion of such audit; otherwise the cost of such audits shall be borne by Tenant. Tenant agrees that this Section 4.6 shall be the sole method to be used by Tenant to dispute the amount of any Direct Expenses payable by Tenant pursuant to the terms of this Lease, and Tenant hereby waives any other rights at law or in equity relating thereto.
