Landlord shall use reasonable efforts to promptly remedy any interruption in the furnishing of services and utilities.
13.2 Should Tenant require any additional work or service, as described above, including services furnished outside of Building Business Hours, Landlord may, on terms to be agreed, upon reasonable advance notice by Tenant, furnish such additional service and Tenant agrees to pay Landlord such charges as may be agreed upon, including any tax imposed thereon, but, with respect to the provision of after-hours HVAC, in no event shall Landlord charge Tenant more than Landlords actual cost for such service plus, where appropriate, a reasonable allowance for depreciation of the HVAC system being used to provide such service. The current charge for after-hours HVAC service, which is subject to change at any time (so long as any increase is limited to Landlords actual cost plus a reasonable allowance for depreciation), is specified on the Reference Pages.
13.3 Wherever heat-generating machines or equipment are used by Tenant in the Premises which affect the temperature otherwise maintained by the air conditioning system or Tenant allows occupancy of the Premises by more persons than the heating and air conditioning system is designed to accommodate, in either event whether with or without Landlords approval, Landlord reserves the right to install supplementary heating and/or air conditioning units in or for the benefit of the Premises and the cost thereof, including the cost of installation and the cost of operations and maintenance, shall be paid by Tenant to Landlord within fifteen (15) days of Landlords demand.
