27. ACCESS OF LANDLORD TO PREMISES
27.1 Subject to the provisions of this Section 27.1, Landlord (through its authorized contractors, agents or representatives) may enter into and upon any part of the Premises during reasonable hours and upon reasonable notice (which shall mean (x) except cases
of emergency, at least 24 hours prior notice to Tenant, and (y) in cases of emergency, such prior notice, if any, or contemporaneous notice, as shall be reasonable under the circumstances), for the following purposes: (i) to make repairs to the Premises as Landlord is required, or expressly authorized, to make pursuant to this Lease, or is required to make during the Term pursuant to any applicable Legal Requirements or any Insurance Requirements; (ii) to otherwise perform Landlords obligations under this Lease; (iii) for the purpose of showing the same to existing or prospective purchasers or lenders; and (iv) at any time during the last twelve (12) months of the Term (assuming no further Extension Option is then available to Tenant), to show the Leased Premises to prospective tenants.
27.2 With respect to any of the aforementioned authorized entries by Landlord into and upon any part of the Premises, Tenant shall be entitled to have its representative accompany Landlord.
27.3 Landlord shall not unreasonably interfere with the operation of Tenants business during any of the aforementioned authorized entries. Without limiting the generality of the foregoing, Landlord shall use commercially reasonable efforts to make any routine repairs requiring access to the Premises after Tenants normal business hours.
27.4 Notwithstanding any of the foregoing, unless otherwise expressly permitted by Tenant in writing, Landlord shall not enter areas designated by Tenant as high security areas, unless an emergency situation exists that requires such entry to prevent imminent threat to human health, safety or material damage to the Premises.
