If Tenant shall require electrical energy for use in the Premises in excess of such reasonable amounts to be furnished, Tenant, at Tenant's expense, shall, if Landlord so elects, install a separate meter(s) for all or any portion or portions of Tenant's electrical energy use and Tenant shall pay for electricity so metered. Upon the installation of such separate meter(s), provided the same accounts for Tenant's total electrical energy usage in the Premises, Tenant shall cease to be obligated to pay the Electrical Energy Charge attributable to any period thereafter. Landlord shall not be liable in any way to Tenant for any failure or defect in the supply or character of electric energy furnished on the Premises by reason of any requirement, act or omission of the public utility serving the Building with electricity. Tenant's use of electric energy in the Premises shall not at any time exceed the capacity of any of the electrical conductors and equipment in or otherwise serving the Premises. In order to insure that such capacity is not exceeded and to avert possible adverse effect upon the Building electric service Tenant shall not, without Landlord's prior written consent in each instance, connect to the 3 square foot Building electric distribution system any fixtures, appliances or equipment (other than lamps, typewriters, small computers, and similar small office machines which operate on a voltage not in excess of Usable Area 110 and which do not require high levels of alternating current) or make any alteration or addition to the electric currentsystem of the Premises. Should Landlord grant such consent, exclusive all additional risers or other equipment required therefor shall be provided by Landlord and the reasonable cost thereof shall be paid by Tenant upon Landlord' s demand. Landlord reserves the right to discontinue furnishing electric energy to Tenant in the Premises at any time upon not less than 30 days notice to Tenant. If Landlord shall exercise such right of electricity termination, from and after the effective date of such termination Landlord shall not be obligated to furnish electric energy to Tenant and thereupon Tenant shall cease to be obligated to pay the Electrical Energy Charge attributable to any period thereafter. If Landlord shall so discontinue furnishing electric energy to Tenant, Tenant shall arrange to obtain electric energy directly from the public utility company furnishing electric service to the Building. Such electric energy may be furnished to Tenant by means of the then existing Building system feeders, risers and wiring to the extent that the same are available, suitable and safe for such purposes. All meters and additional panel boards, feeders, risers, wiring and other conductors and equipment which may be required to operate the 4 base Building systems, provided that the branch circuits initially obtain electric energy directly from such public utility company shall be installed by Landlord as per the 5 electrical drawings of the Final Basic Building Plans as part of Basic Construction (including, without 6 limitation, lighting and convenience power on each floor and power to flushometers and sinks, if any, 7 but not including stair power or exit signs) shall be transferred to the appropriate local floor panel of 8 each floor of the Demised Premises by Tenant as part of at Tenant's Work upon and subject to the 9 applicable terms expense before discontinuance of this Lease. Such services shall be provided as set forth in the Work Letter. The 10 distribution of electricity from the bus duct shall be transformed, sized and configured as per the 11 electrical drawings of the Final Basic Building Plansservice. Landlord shall furnish to the DX units serving 12 each floor of the Demised Premises, through the distribution facilities to be installed as provided in the 13 Work Letter, alternating electric current in a type and amount required to operate such DX units and 14 Tenant's Special Equipment. 15 B. The electric current for the Premises, the DX units, Tenant's Special Equipment, 16 service elevator corridors located within the Premises and all other electrical, telecommunications and 17 mechanical equipment exclusively serving the Premises (and any supplemental bus duct taps, separate 18 risers and/or any other items installed in accordance with the terms of the second (2nd) sentence of 19 Section 7.02 hereof) shall be measured by submeter(s) with coincident demand (and shall be billed as if 20 there was only one (1) submeter provided therefor in the aggregate), installed and maintained by Tenant, 21 at its cost and expense, at such location(s) reasonably selected by Landlord, and Tenant shall pay 22 monthly to Landlord such amounts (which shall be computed by using the Electric Rates, as hereinafter 23 defined), on the basis of Tenant's consumption of/demand for alternating current in the foregoing areas. 24 Notwithstanding the foregoing the submeter(s) for any supplemental bus duct taps, separate risers and/or 25 any other items installed in accordance with the terms of the second (2nd) sentence of Section 7.02 26 hereof may not be measured with coincident demand (it being agreed that Tenant shall pay Landlord as 27 additional rent for the cost of the installation and maintenance thereof, which cost shall be equal to 28 Landlord's Cost therefor). If Landlord determines that it is not reasonably feasible to meter any portion 29 of Tenant’s use of electricity, then such usage shall be determined from a survey at Tenant’s expense 30 made by a reputable independent electrical engineer or consultant selected by Landlord or a qualified 31 member of Landlord’s in-house personnel. If Landlord causes any such survey to be performed, 32 Landlord shall send a copy of such survey to Tenant together with a Notice providing that Tenant has a 33 period of sixty (60) days following receipt of Landlord’s findings and such Notice to dispute Landlord’s 34 findings. If Tenant shall dispute the findings of such survey, Tenant, within sixty (60) days of receipt of 35 Landlord’s findings and such Notice (time being of the essence), may cause a like survey to be made by 36 an independent, reputable electric consultant selected and paid by Tenant. If Tenant so elects, upon 37 completion of the second survey, Tenant shall deliver Notice to Landlord of the results thereof. If such 38 determination differs from that of Landlord by 10% or less, Landlord’s findings shall be conclusive and 39 binding upon the parties. If such determination differs from that made by Landlord by more than 10% 40 and Landlord and Tenant cannot agree on the amount of such electric use, the dispute may be resolved 41 by arbitration in accordance with the terms of Article 25 hereof, except that the arbitrators shall be 42 qualified electrical engineers or consultants having at least ten (10) years’ active, continuous experience 43 in electrical work or consultation with respect to first-class office buildings in the Borough of 44 Manhattan. Pending a final determination pursuant to such arbitration, Tenant shall pay to Landlord for 45 electrical energy based on the determination of Landlord; and if it is determined that Tenant has 46 overpaid, Landlord shall reimburse Tenant (by either, at the sole option of Landlord, providing a credit 47 against the next payment(s) of Rent payable by Tenant hereunder or paying such sum to Tenant) for any 48 overpayment at the conclusion of such arbitration. If Tenant shall not timely dispute the findings of 49 Landlord as provided in this Section 7.01B, the determination by Landlord shall be deemed to be final 50 and conclusive. 1 C. Landlord and its agents shall be permitted access to the electric closets and the 2 meters at reasonable times after delivery of a reasonable prior Routine Notice to Tenant, which may be 3 oral (except in the event of an emergency, when no such Routine Notice or oral notice shall be required). 4 Tenant shall supply, install at Tenant's costexpense all replacement lighting tubes, adequate electric lighting lamps, bulbs, and electric power to Landlord or 5 Landlord's contractors to make repairs ballasts required in the Demised Premises.
