In accordance with the Work Schedule and the Preliminary Plans, the Architect will prepare complete architectural plans and complete, fully-engineered construction drawings and specifications for all of Landlord’s Work, including mechanical, electrical, plumbing and structural elements (collectively the “Final Plans”). The Final Plans will show: (i) the subdivision (including partitions and walls), layout, lighting, finish and decoration work (including carpeting and other floor coverings) for the Premises; (ii) all internal and external communications and utility facilities which will require the installation of conduits or other improvements from the base Building shell; and (iii) all other specifications for Landlord’s Work.

Tenant agrees to approve in writing the revised Excess Cost Summary within five business days of its receipt thereof. If Tenant fails to timely

deliver to Landlord written approval of the Excess Cost Summary, the Excess Cost Summary shall be deemed approved by Tenant. Tenant’s approval of the Excess Cost Summary shall constitute Tenant’s agreement to pay Landlord the Excess Costs.
