The term (the “Term”) of this Sublease shall be for the period commencing (i) as to the Phase I Premises, on the date Master Lessor delivers possession of the entirety of the Phase I Premises to Sublessor, which is anticipated to be July 1, 2017 (the “Phase I Delivery Date”) and (ii) as to the Phase II Premises, on the date Master Lessor delivers possession of the entirety of the Phase II Premises to Sublessor, which is anticipated to be August 1, 2017 (the “Phase II Delivery Date”), and ending on July 31, 2019 (the “Expiration Date”), unless this Sublease is sooner terminated pursuant to its terms. The earlier of the Phase I Delivery Date and Phase II Delivery Date (each, a “Delivery Date”) shall be referred to herein as the “Commencement Date”. Notwithstanding that the defined terms for the Phases include “I” and “II”, Sublessee acknowledges that the Phase II Delivery Date, and thereby the Commencement Date, could occur before the Phase I Delivery Date. To the extent an Extension Option (as defined below) is exercised pursuant to Paragraph 25 herein, the Term of this Sublease shall be extended to include the Extension Period (as defined below). References in this Sublease to the “Subleased Premises” shall not include the Phase I Premises until the Phase I Delivery Date and shall not include the Phase II Premises until the Phase II Delivery Date. The parties acknowledge that Sublessee is already in occupancy of the first (1 st ) through fifth (5 th ) floors of the Building as a subtenant of the current tenants therein and Sublessor shall accordingly not be required to actually tender delivery of the first (1 st ) through fifth (5 th ) floors of the Building. The parties also acknowledge that an unaffiliated third party is currently in occupancy of the sixth (6 th ) floor of the Building as a subtenant of the current tenant therein. Sublessor shall use commercially reasonable efforts (without requiring Sublessor to expend more than a nominal sum unless Sublessee reimburses Sublessor for such expenses) to cause Master Lessor to enforce the termination provisions of the existing lease for the sixth (6 th ) floor of the Building such that the Phase I Delivery Date occurs on July 1, 2017.
