ENTRY BY LANDLORD 21.01 Landlord may enter the Premises at all reasonable times to: inspect the same; exhibit the same to prospective purchasers, Mortgagees or tenants; determine whether Tenant is complying with all of its obligations under this Lease; supply janitorial and other services to be provided by Landlord to Tenant under this Lease; post notices of non-responsibility; and make repairs or improvements in or to the Building or the Premises; provided, however, that all such work shall be done as promptly as reasonably possible and so as to cause as little interference to Tenant as reasonably possible. Tenant hereby waives any claim for damages for any injury or inconvenience to, or interference with, Tenant's business, any loss of occupancy or quiet enjoyment of the Premises or any other loss occasioned by such entry. Landlord shall at all times have and retain a key with which to unlock all of the doors in, on or about the Premises (excluding Tenant's vaults, safes and similar areas designated by Tenant in writing in advance), and Landlord shall have the right to use any and all means by which Landlord may deem proper to open such doors to obtain entry to the Premises, and any entry to the Premises obtained by Landlord by any such means, or otherwise, shall not under any circumstances be deemed or construed to be a forcible or unlawful entry into or a detainer of the Premises or an eviction, actual or constructive, of Tenant from any part of the Premises. Such entry by Landlord shall not act as a termination of Tenant's duties under this Lease. If Landlord shall be required to obtain entry by means other than a key provided by Tenant, the cost of such entry shall by payable by Tenant to Landlord as additional rent.
