Original Lease The single executed original of this Lease marked "THIS COUNTERPART IS THE ORIGINAL EXECUTED COUNTERPART" on the signature page thereof and containing the receipt of the Lessor therefor on or following the signature page thereof shall be the Original Executed Counterpart of this Lease (the "Original Executed Counterpart"). To the extent that this Lease constitutes chattel paper, as such term is defined in the Uniform Commercial Code as in effect in any applicable jurisdiction, no security interest in this Lease may be created through the transfer or possession of any counterpart other than the Original Executed Counterpart.
Amendments to Lease The Lease is hereby amended as follows:
Modification of Lease Should any current or prospective mortgagee or ground lessor for the Building or Project require a modification of this Lease, which modification will not cause an increased cost or expense to Tenant or in any other way materially and adversely change the rights and obligations of Tenant hereunder, then and in such event, Tenant agrees that this Lease may be so modified and agrees to execute whatever documents are reasonably required therefor and to deliver the same to Landlord within ten (10) business days following a request therefor. At the request of Landlord or any mortgagee or ground lessor, Tenant agrees to execute a short form of Lease and deliver the same to Landlord within ten (10) business days following the request therefor.
Amendment and Modification This Agreement may only be amended, modified or supplemented by an agreement in writing signed by each party hereto.
Amendment and Modification; Waiver This Agreement may only be amended, modified or supplemented by an agreement in writing signed by each party hereto. No waiver by any party of any of the provisions hereof shall be effective unless explicitly set forth in writing and signed by the party so waiving. No waiver by any party shall operate or be construed as a waiver in respect of any failure, breach or default not expressly identified by such written waiver, whether of a similar or different character, and whether occurring before or after that waiver. No failure to exercise, or delay in exercising, any right, remedy, power or privilege arising from this Agreement shall operate or be construed as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.
Modification of Agreement This Agreement may be modified, amended, suspended or terminated, and any terms or conditions may be waived, but only by a written instrument executed by the parties hereto.
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.
Amendment and Modifications This Agreement may not be amended, modified or supplemented except by an instrument or instruments in writing signed by the party against whom enforcement of any such amendment, modification or supplement is sought.
