Common use of Electrical Service Clause in Contracts

Electrical Service. A. Landlord shall supply electricity to the Premises to meet a requirement not to exceed 3.0 xxxxx per square foot of Premises Rentable Area for lighting and for office machines through standard receptacles for standard single-phase 120 volt alternating current. Tenant agrees in its use of the Premises not to exceed such requirement and that its total connected lighting load will not exceed the maximum from time to time permitted under applicable governmental regulations. Landlord shall purchase and install, at Tenant's expense (other than those in place as of the Commencement Date), all lamps, tubes, bulbs, starters and ballasts. Tenant shall pay all charges for electricity used or consumed in the Premises. Landlord shall bear the cost of installation, repair and maintenance of any electric meter to be used or installed in the Premises. In order to assure that the foregoing requirements are not exceeded and to avert any possible adverse affect on the Building's electric system, Tenant shall not, without Landlord's prior written consent, which consent shall not be unreasonably withheld or delayed, connect any fixtures, appliances or equipment to the Building's electric distribution system other than typewriters, pencil sharpener, adding machines, handheld or desk top calculators, dictaphones, clocks, personal computers and radios.

The Excess Electricity Use Charge specified in such Excess Electricity Notice shall be due and payable as additional rent as hereinafter provided. Any Excess Electricity Use Charge allocable to a period prior to the date of giving an Excess Electricity Notice shall, at the option of Landlord, be payable as additional rent within thirty (30) days after written demand is made therefor by Landlord. Excess Electricity Use Charges allocable to any period after the date of giving an Excess Electricity Notice shall be due and payable as additional rent monthly in advance in equal monthly installments for the balance of the Term of this Lease on the first day of each calendar month during the Term of this Lease with the first such installment being due and payable on the first day of the first full calendar month following the date of giving any such Excess Electricity Notice.

Electrical Service. A. Landlord shall The City, which owns and operates its electrical service utility, agrees that it will, at its expense, increase the electrical service and distribution to meet the electrical service demands of Jackpot at the Building in accordance with the Project schedule attached hereto and incorporated herein as Exhibit 6 (the “Project Schedule”). The City acknowledges that Jackpot’s electrical service demands for the Subject Property as estimated on Exhibit 7 (the “Minimum Electrical Requirements”), and the City agrees to provide the Minimum Electrical Requirements in accordance with Exhibit 7. As set forth in Recital G(2), the City will commit to funding up to $2,000,000.00 of the total anticipated cost of the improvements on the Subject Property and Jackpot will be responsible for funding any remaining anticipated cost of the improvements from the distribution substation, which includes the cost of the transformers or primary metering. The City will provide transformers at its distribution substation to supply electricity the sufficient electrical service to the Premises Subject Property to meet a requirement not the Minimum Electrical Requirements and support Jackpot’s operation. Jackpot acknowledges that the City is expending great sums to exceed 3.0 xxxxx per square foot of Premises Rentable Area for lighting enhance the distribution service to its Building and for office machines through standard receptacles for standard single-phase 120 volt alternating current. Tenant agrees in its use the expansion and upsizing of the Premises not distribution substation to exceed accommodate Jackpot’s operations. As such, Jackpot agrees to purchase from the City no less than the monthly electrical service set forth on Exhibit 4 (the “Minimum Monthly Amount”) until the sooner of (i) eight (8) years following the completion of the Project or (ii) until the City has recovered the Project Cost, whichever occurs first (the “Minimum Service Period”), provided that Jackpot shall have no obligation to purchase the Minimum Monthly Amount for any period in which the City has failed to complete its obligations with respect to the Project and to provide the Minimum Electrical Requirements sufficient to meet Jackpot’s projected electrical needs. If Jackpot fails to purchase the Minimum Monthly Amount in any monthly period (a “Deficiency”), Jackpot shall pay the City within sixty (60) days after the end of the calendar year in which such requirement monthly period occurs an amount equal to the standard applicable cost of the electrical service multiplied by the Deficiency (the “Minimum Payment”). For clarity, the Deficiency is the shortfall of the electrical service actually purchased during a monthly period and the Minimum Monthly Amount. Payments made by Jackpot to the City to purchase electrical services during the Minimum Service Period and Minimum Payments shall count as Jackpot’s reimbursements to the City for the Project Cost. Notwithstanding the foregoing, if Jackpot purchases more electrical service than the Minimum Monthly Amount for any particular month, such excess may be carried forward and applied to a future monthly period and such excess may offset and be credited against any Deficiency for such month, provided that its total connected lighting load will not exceed any excess during Off- Peak Months may only be credited against future Off-Peak Months and any excess during Peak Months may only be credited against future Peak Months. For purposes of this Agreement, “Peak Months” means June, July, August and September, and “Off-Peak Months” means January, February, March, April, May, October, November and December. Should Jackpot wish to terminate the maximum from time obligation to time permitted under applicable governmental regulations. Landlord shall purchase and installthe Minimum Monthly Amount before expiration of the Minimum Service Period, at Tenant's expense (other than those in place Jackpot may make a lump sum payment equal to the outstanding amount of yet reimbursed Project Cost as of the Commencement Dateend of the calendar year immediately preceding the termination date (“Amount Owed”). The Amount Owed shall equal to the Project Cost less cumulative reimbursements Jackpot paid to City equal to the amount determined by a straight-line amortization of the Project Cost over a period of eight (8) years (as an example, all lampsthe Amount Owed as of the end of Year 2 shall be $3,825,0000, tubesnamely, bulbs$5,100,000 less $1,275,000 or $637,500 multiplied by two years). However, starters the use of third-party electrical providers any other generation source, including, but not limited to solar generation, wind generation, any form of reusable generation, or any other form of generation that would reduce, augment, supplement, or replace the electrical load shall be subject to the City’s codes and ballasts. Tenant shall pay all charges for electricity used or consumed in the Premises. Landlord shall bear the cost of installation, repair and maintenance City Council’s approval of any other such generation source. For the purposes of electrical rates, Jackpot shall be categorized and billed as a Class Rate 168 customer. No alternative rate class or discounted rates shall be afforded to Jackpot, unless specifically set forth herein. During the twelve (12) months preceding the expiration of the Minimum Service Period, the parties shall cooperate in good faith to secure the power purchase and the electric meter billing rates for utility services potentially provided by the City to be used or installed in the PremisesJackpot post- termination of this Agreement. In order to assure SECTION THREE.
