“Section 16.13. Option to Extend.

(a) Grant and Exercise of Option. Provided that (i) Tenant has not been in Default at any time during the Lease Term, (ii) the creditworthiness of Tenant is then reasonably acceptable to Landlord, (iii) Tenant originally named herein remains in possession of and has been continuously operating in the entire Leased Premises throughout the Lease Term, and, (iv) the current use of the Leased Premises is acceptable to Landlord, Tenant shall have one (1) option to extend the Lease Term for one (1) additional period of three (3) years (the “Extension Term”). The Extension Term shall be upon the same terms and conditions contained in the Lease except (x) Tenant shall not have any further option to extend, (y) any improvement allowances or other concessions applicable to the Leased Premises under the Lease shall not apply to the Extension Term, and (z) the Minimum Annual Rent shall be adjusted as set forth herein (“Rent Adjustment”). Tenant shall exercise such option by delivering to Landlord, no later than nine (9) months prior to the expiration of the current Lease Term, written notice of Tenant’s desire to extend the Lease Term. Tenant’s failure to properly exercise such option shall be deemed a waiver of such option. If Tenant properly exercises its option to extend, Landlord shall notify Tenant of the Rent Adjustment no later than thirty (30) days after receipt of Tenant’s notice of its exercise of this option to extend. Tenant shall be deemed to have accepted the Rent Adjustment if it fails to deliver to Landlord a written objection thereto within five (5) business days after receipt thereof. If Tenant properly exercises its option to extend, Landlord and Tenant shall execute an amendment to the Lease (or, at Landlord’s option, a new lease on the form then in use for the Building) reflecting the terms and conditions of the Extension Term within thirty (30) days after Tenant’s acceptance (or deemed acceptance) of the Rent Adjustment.

The Minimum Annual Rent for the Extension Term shall be an amount equal to the Minimum Annual Rent then being quoted by Landlord to prospective renewing tenants of the Building for space of comparable size and quality and with similar or equivalent improvements as are found in the Building, and if none, then in similar buildings in the immediate vicinity; provided, however, that in no event shall the Minimum Annual Rent during the Extension Term be less than the highest Minimum Annual Rent payable during the immediately preceding term. The Monthly Rental Installments shall be an amount equal to one-twelfth (1/12) of the Minimum Annual Rent for the Extension Term and shall be paid at the same time and in the same manner as provided in the Lease.”

9. Deletion of Section 16.16. Landlord’s Allowance for Future Improvement. Section 16.16 of the Lease is hereby deleted in its entirety and shall be of no further force or effect.

10. Incorporation of Section 16.17. Patriot Act. The following is hereby incorporated as Section 16.17 of the Lease:
