3. Expansion Space Term. The Term for Tenant’s lease of the Expansion Space (“Expansion Space Term”) shall commence on the Expansion Commencement Date and shall expire co-terminous with Tenant’s lease of the Existing Premises on July 31, 2016 (the “Expiration Date”); provided, however, that Tenant shall have the right to terminate Tenant’s lease of either the Suite 300 Portion or the Suite 305 Portion, or both, upon one hundred twenty (120) days prior written notice to Landlord deliverable at any time in the sole discretion of Tenant. If Tenant elects to terminate the lease of all or any part of the Expansion Space pursuant to the foregoing termination right, Landlord and Tenant shall thereafter promptly execute a new amendment to the Lease, in a form acceptable to both Landlord and Tenant, modifying the Basic Rental, Tenant’s Proportionate Share. Tenant’s parking allocation, and any other provision of the Lease necessary to account for such termination. Landlord shall provide Tenant with access to the Expansion Space upon full execution and delivery of this Third Amendment by Landlord and Tenant for the purposes of installing Tenant’s furniture, fixtures, and equipment and Tenant’s telephone, network, and data cabling, and Tenant shall have no obligation to pay Basic Rental with respect to the Expansion Space during the period of such access; provided, however, that (i) Tenant’s access hall not interfere with Landlord’s completion of the Improvements, (ii) Tenant shall provide a certificate of insurance in accordance with Article 14 of the Original Lease for the Expansion Space prior to such entry, and (iii) the terms and conditions of Section 13(a) of the Lease shall apply to such access by Tenant.

Notwithstanding anything to the contrary in the Lease, during the Expansion Space Term, (i) Tenant’s Proportionate Share for the Expansion Space shall be 2.88% after the Expansion Commencement Date; and (ii) the Base Year for the Expansion Space shall be the calendar year 2014.

6. Improvements to the Expansion Space. Promptly after full execution and delivery of this Third Amendment, Landlord shall, at Landlord’s sole cost and expense and using readily-available Building-standard materials (collectively, the “Improvements”), (i) repaint currently painted walls throughout the Expansion Space; (ii) steam clean currently carpeted floors throughout the Expansion Space; and (iii) create a five-foot wide opening in the existing demising wall between Suites 310 and 305 as depicted on EXHIBIT A attached hereto, and move the existing demising wall between Suite 300 and Suite 360 to the location depicted on EXHIBIT A attached hereto (item (iii) to be referred to herein as the “Suite Configuration Work”). Landlord and Tenant hereby acknowledge that the Improvements, other than the Suite Configuration Work, shall be completed by Landlord prior to the Expansion Commencement Date. Landlord and Tenant hereby acknowledge that the Suite Configuration Work may be completed by Landlord after the Expansion Commencement Date, but any such work after the Expansion Commencement Date shall be performed during non-normal business hours. Tenant hereby agrees that the performance of the Improvements shall in no way constitute a constructive eviction of Tenant nor entitle Tenant to any abatement of Basic Rental for the Expansion Space payable pursuant to this Third Amendment. Landlord shall have no responsibility or for any reason be liable to Tenant for any direct or indirect injury to or interference with Tenant’s business arising from the performance of the Improvements, nor shall Tenant be entitled to any compensation or damages from Landlord for loss of the use of the whole or any part of the Expansion Space resulting from the performance of the Improvements or for any inconvenience or annoyance occasioned by the performance of the Improvements.
