3.Standard of Construction.Tenant's Work shall comply with all applicable laws, codes, rules and
regulations of all governmental and quasi-governmental authorities with jurisdiction. Only new and first-class materials shall be used in the construction of Tenant's Work. Tenant shall not change in
any material respect any portion of Tenant's Work from the description thereof contained in Tenant's Final Plans, as approved by Landlord, unless Tenant first obtains Landlord's written approval,
