3.04    [Intentionally Omitted.]

3.05    Landlord’s Work to both the Existing Premises and the Additional Space shall be deemed to be substantially completed notwithstanding that (i) minor or non-material details of construction, mechanical adjustment or decoration remain to be performed (collectively, the “Punch List Items”), or (ii) a portion of Landlord’s Work is incomplete because construction scheduling requires that such work be done after incomplete finishing or after other work to be done by or on behalf of Tenant is completed.
