Amendment to Lease If Tenant timely exercises Tenant’s right to lease the Availability Premises or any portion thereof as set forth herein, then, within fifteen (15) days thereafter, Landlord and Tenant shall execute an amendment adding such Availability Premises to this Lease upon the same terms and conditions as the Initial Premises, except as otherwise set forth in this Section 1.4 or the Availability Notice, and provided that the terms of the Tenant Work Letter shall not apply with respect to the Availability Premises (except as otherwise provided in Section 1.4.5, above); provided, however, an otherwise valid exercise of Tenant’s right of availability shall be of full force and effect irrespective of whether such amendment is ever signed by Landlord and Tenant. Except to the extent inconsistent with the determination of Availability Premises Rent, all provisions of the Lease which vary based upon the rentable and usable square footage of the Premises shall be adjusted to reflect the addition of such Availability Premises to the Premises; provided, however, the L-C Amount shall be increased pursuant to the terms of Section 21.7 of this Lease, below. The rentable square footage of such Availability Premises shall be determined in accordance with the terms of Section 1.2 of this Lease. To the extent Tenant exercises its right of first offer with respect to any portion of the Availability Premises during the first (1st) year after the Lease Commencement Date, Tenant shall commence payment of Availability Premises Rent and Excess as to such space to Landlord upon that date (the “Availability Premises Rent Commencement Date”) which is two hundred ten (210) days after the later of the delivery date set forth in the Availability Notice and the date Landlord delivers the Availability Premises in the Delivery Condition (the “Availability Premises Lease Commencement Date”). To the extent Tenant exercises its right of availability with respect to any portion of the Availability Premises anytime after the first (1st) anniversary of the Lease Commencement Date, the Availability Premises Rent Commencement Date shall occur one hundred eighty (180) days after the Availability Premises Lease Commencement Date. In all cases, the lease term of the Availability Premises (or any portion thereof) shall expire on the Lease Expiration Date, subject to extension of this Lease; provided, however, in the event the remaining Lease Term is less than thirty-six (36) months from the applicable Availability Premises Rent Commencement Date, then the Lease Term shall be extended for a period of time sufficient for Tenant’s lease of the Premises to be coterminous with Tenant’s lease of the Availability Premises (which shall be thirty-six (36) months from the applicable Availability Premises Rent Commencement Date), and the base rental rate for the Premises during this extended period shall be adjusted to Market Rent for the Premises determined in accordance with Section 2.2.4 and the Base Year shall be the year in which the Lease would have otherwise expired (if on or before July 31) or the following year (if after July 31). This extension shall have no impact on Tenant’s extension rights hereunder, which may be exercised at the end of the extended Lease Term. This Lease shall commence as to the Availability Premises (and references to Premises shall include the applicable Availability Premises) on the Availability Premises Lease Commencement Date.
