Landlord’s Work shall be deemed substantially completed notwithstanding the fact that (I) minor or insubstantial details of construction, mechanical adjustment or decoration remain to be performed or (II) portions of Landlord’s Work have not been completed because under good construction scheduling, such work should not be done until after still incomplete finishing or other work to be done by Tenant is completed.  If the substantial completion of Landlord’s Work shall be delayed due to any act or omission of Tenant or its employees, agents or contractors (including but not limited to any delays due to any additional work that Tenant authorizes the Landlord to perform) or the inclusion in Landlord’s work of any work that is long-lead in nature, then, the substantial completion of Landlords Work shall be deemed to have occurred on the date when Landlord’s Work would have been substantially completed but for said delay.

Any additional work that Tenant authorizes the Landlord to perform will be at the sole cost and expense of the Tenant and will include a fee of 21% of the actual cost to the Landlord for the Landlord’s supervision and overhead. Tenant will execute a Work Authorization Form prepared by the Landlord and issue a check for the full amount of the cost of such work (including 21%) PRIOR to the Landlord performing any such work.  Failing the execution of such Work Authorization Form and payment, Landlord shall perform only such work as is presently shown on this Schedule 13.  However, nothing contained herein shall obligate Landlord to perform any such additional work absent Landlord agreeing to do so.
