Tenant shall cause such Persons to perform such exterminating in a manner that is reasonably satisfactory to Landlord.

(C) Tenant, at Tenant’s expense, shall clean daily all portions of the Premises used for the storage, preparation, service or consumption of food or beverages. Tenant shall not have the right to perform any cleaning services (or any other similar facilities management services such as, for example, matron services or handyman services) in the Premises using any Person other than the cleaning contractor that Landlord has engaged from time to time to perform cleaning services in the Building for Landlord; provided, however, that (x) Landlord shall not have the right to require Tenant to use such cleaning contractor unless the rates that such cleaning contractor agrees to charge Tenant for such additional cleaning services are commercially reasonable, and (y) subject to Section 4.8 hereof, Tenant shall have the right to use Tenant’s own employees for such additional cleaning services.
