(a) The Term of the Lease for the Replacement Space shall commence on the date (the “Replacement Space Commencement Date”) which shall be the earlier of the date on which Landlord’s Work has been substantially completed (or would have been substantially completed except by reason of any delay caused by Tenant), or the date on which Tenant occupies any portion of the Replacement Space except as set forth in Section 2(d) hereinbelow. Landlord’s Work shall be deemed substantially completed at such time as the only items of Landlord’s Work to be completed are those of a “punch-list” nature which do not substantially interfere with Tenant’s use and occupancy of the Replacement Space. The Term of the Lease is hereby extended to June 30, 2018 (the “New Expiration Date”), subject to Tenant’s option to extend the Term as set forth in Section 2(c) hereinbelow.
