Tenant's Proportionate Share shall be calculated by dividing the __________ rentable square feet of the Premises by the ________ net rentable square feet of the Building, which equals ____ %.

The annual statement of Operating Expenses shall be accounted for and reported in accordance with generally accepted accounting principles (the "Annual Statement"). If Tenant disputes the amount of Operating Expenses as set forth in the Annual Statement from the Landlord, then Tenant may have Landlord's books and records relating to Operating Expenses audited by a qualified professional selected by Tenant or by Tenant itself, provided (i) Tenant gives written notice of the audit within forty-five (45) days of Tenant's receipt of the Annual Statement, and (ii) Tenant is not in default under the Lease beyond any applicable notice and cure period provided for therein. No subtenant shall have any right to conduct an audit and no assigns shall conduct an audit for any period during which such assignee was not in possession of the Premises. Books and records necessary to accomplish any audit permitted under this Section shall be retained for twelve months after the end of each calendar year, and on receipt of notice of Tenant's dispute of the Operating Expenses shall be made available to Tenant to conduct the audit, which (at Landlord's option) may be either at the Premises, at the Landlord's division office for the area in which the Premises are located, or at Landlord's home office in Raleigh, North Carolina.

In the event that the Tenant elects to have a professional audit Landlord's Operating Expenses as provided in this Lease, such audit must be conducted by an independent nationally or regionally recognized accounting firm that is not being compensated by Tenant on a contingency fee basis. All information obtained through such audit as well as any compromise, settlement or adjustment reached as a result of such audit shall be held in strict confidence by Tenant and its officers, agents, and employees and as a condition to such audit, the Tenant's auditor shall execute a written agreement agreeing that the auditor is not being compensated on a contingency fee basis and that all information obtained through such audit as well as any compromise, settlement or adjustment reached as a result of such audit, shall be held in strict confidence and shall not be revealed in any manner to any person except upon the prior written consent of the Landlord, which consent may be withheld in Landlord's sole discretion, or if required pursuant to any litigation between Landlord and Tenant materially related to the facts disclosed by such audit, or if required by law. If Operating Expenses were overstated by [five percent (5%)] or more, then Landlord shall reimburse Tenant for its reasonable audit costs; otherwise, Tenant shall pay its own audit costs. In the event the audit process reveals that Tenant has overpaid its proportionate share of Operating Expenses, such overpayment shall be credited against Tenant's future Rent payments or, if the Expiration Date has occurred, Landlord shall reimburse Tenant for the full amount of such overpayment within thirty (30) days after completion of the audit process.
