Tenant has inspected the building and the demised premises and is thoroughly acquainted with their condition and agrees to take the same "as is" on the date possession is tendered and acknowledges that the taking of possession of the demised premises by Tenant shall be conclusive evidence that the said premises and the building of which the same form a part were in good and satisfactory condition at the time such possession was so taken, except as to latent defects. All understandings and agreements heretofore made between the parties hereto are merged in this contract, which alone fully and completely expresses the agreement between Owner and Tenant and any executory agreement hereafter made shall be ineffective to change, modify, discharge or effect an abandonment of it in whole or in part, unless such executory agreement is in writing and signed by the party against whom enforcement of the change, modification, discharge or abandonment is sought.

Quiet Enjoyment: 23. Owner covenants and agrees with Tenant that upon Tenant paying the rent and additional rent and observing and performing all the terms, covenants and conditions, on Tenant's part to be observed and performed, Tenant may peaceably and quietly enjoy the premises hereby demised, subject, nevertheless, to the terms and conditions of this lease including, but not limited to, Article 34 hereof and to the ground leases, underlying leases and mortgages hereinbefore mentioned. Failure to Give Possession: 24. If Owner is unable to give possession of the demised premises on the date of the commencement of the term hereof, because of the holding-over or retention of possession of any Tenant, undertenant or occupants or if the demised premises are located in a building being constructed, because such building has not been sufficiently completed to make the premises ready for occupancy or because of the fact that a certificate of occupancy has not been procured or if Owner has not completed any work required to be performed by Owner, or for any other reason, Owner shall not be subject to any liability for failure to give possession on said date and the validity of the lease shall not be unpaired under such circumstances, nor shall the same be construed in any wise to extend the term of this lease, but the rent payable hereunder shall be abated (provided Tenant is not responsible for Owner's inability to obtain possession or complete any work required) until after Owner shall have given Tenant notice that Owner is able to deliver possession in the condition required by this lease. If permission is given to Tenant to enter into the possession of the demised premises or to occupy premises other than the demised premises prior to time date specified as the commencement of the term of this lease, Tenant covenants and agrees that such possession and/or occupancy shall be deemed to be under all the terms, covenants, conditions and provisions of this lease, except the obligation to pay the fixed annual rent set forth in page one of this lease.

All checks tendered to Owner as and for the rent of the demised premises shall be deemed payments for the account of Tenant. Acceptance by Owner of rent from anyone other than Tenant shall not be deemed to operate as an attornment to Owner by the payor of such rent or as a consent by Owner to any assignment or subletting by Tenant of the demised premises to such payor, or as a modification of the provisions of this lease. No act or thing done by Owner or Owner's agents during the term hereby demised shall be deemed an acceptance of a surrender of said premises and no agreement to accept such surrender shall be valid unless in writing signed by Owner. No employee of Owner or Owner's agent shall have any power to accept the keys of said premises prior to the termination of the lease and the delivery of keys to any such agent or employee shall not operate as a termination of the lease or a surrender of the premises.

In order to insure that such capacity is not exceeded and to avert any possible adverse effect upon the building's electric service, Tenant shall not, without Landlord's prior written consent in each instance, connect any fixtures, appliances of equipment (other than a reasonable number of table or floor [ILLEGIBLE], typewriters and similar small office machines using comparable electric current) to the building's electric distribution system [ILLEGIBLE]make any alteration or addition to the electric system of the demised premises. Should Landlord grant such consent, all additional [ILLEGIBLE]or other equipment required therefor shall be provided by Landlord, and all costs and expenses in connection therewith, including, without limitation, those for filing and supervision, shall be paid by Tenant upon Landlord's demand, as additional rent, without setoff or deduction. As a condition to granting such consent, Landlord may require Tenant to agree to an increase in the annual rent by any amount which will reflect the value to Tenant of the additional service to be furnished by Landlord, to wit: the potential additional electric current to be made available to Tenant based upon the estimated initial total capacity of such additional [ILLEGIBLE] or other equipment. If Landlord and Tenant cannot agree on the amount of such annual rent increase, the same shall be determined by a reputable electrical consultant, to be selected by Landlord and paid equally by both parties. The parties shall then execute an agreement prepared by Landlord amending this lease and setting forth the new annual rent resulting from such increase and confirming the effective date thereof, but such increase shall be effective from such date even if such agreement is not executed. E. Landlord reserves the right to discontinue furnishing electric current to Tenant in the demised premises at any time upon not less than thirty (30) days' notice to Tenant. F. If Landlord, at Landlord's option, (i) exercises such right of discontinuance as provided in clause E, or (ii) requires Tenant to initially obtain its electric current directly from the public utility corporation supplying electric current to the building, this lease shall continue in full force and effect and shall be unaffected thereby, except only that, from and after the effective date of such discontinuance, or the commencement of direct usage, as the case may be, Landlord shall not be obligated to furnish electric current to Tenant and except that, if Landlord shall have been furnishing electric current on a rent inclusion basis, from and after the effective date of such discontinuance, the annual rent payable under this lease shall be reduced by an amount equal to the aggregate amount of all increases to the annual rent reserved herein pursuant to clause B of this Article. In either aforesaid event, if Landlord is not to furnish electric current to Tenant, Tenant shall arrange to obtain electric current directly from the public utility corporation supplying electric current to the building; and in any event, all risers, equipment and other facilities which may be required for Tenant to obtain electric current directly form such public utility corporation shall, at Tenant's expense, payable to Landlord upon demand, as additional rent, without [ILLEGIBLE] or deduction, be installed by Landlord, if in Landlord's judgment the same are necessary and will not cause damage or injury to the building or any part thereof or create a hazardous condition or entail excessive alterations, repairs or expense or [ILLEGIBLE] with or (CONTINUED) disturb any other building tenants or occupants; and in nay event, any such installation shall be maintained by Tenant, at its expense, and shall be subject to such conditions as Landlord and/or the public utility corporation may require. If Landlord shall not furnish electric current to Tenant, it shall not be liable to Tenant therefor and the same shall not be deemed to be a lessening or diminution of services within the meaning of any law, rule or regulation now or hereafter enacted, promulgated or issued. G. If any taxes or charges are or shall be imposed upon Landlord or its agent in connection with the sale or resale of electrical energy to Tenant, Tenant covenants and agrees that, where permitted by law, Tenant's pro-rata share of such taxes or charges shall be passed on to Tenant and paid by Tenant to Landlord or its agents upon demand, as additional rent, without set-off or deduction. At all times during the term of this lease Tenant will comply with all present and future General Rules, Regulations, Terms and Conditions applicable to service equipment, wiring and Requirements in accordance with the regulations of the public utility corporation supplying electric current to the building. H. In the event that any increased or additional rent under this article is not paid within 30 days after a bill is rendered, Landlord may, upon at least ten (10) days' prior written notice to Tenant without further notice and without waiving its rights to any other remedy or remedies it may have, discontinue the service of electric current to the demised premises without releasing Tenant by such discontinuance of service. I. Tenant covenants and agrees that at no time will the connected electrical load for any one full or partial floor of the demises premises exceed 6 watts per square foot of usable area unless the rent has been increased pursuant to this Article to reflect the additional load. J. It is agreed that Landlord, from time to time may change the method of supplying electric current to Tenant at the demised premises in any manner referred to in this lease or otherwise, provided that in so doing Landlord shall comply with all applicable laws. Notwithstanding anything to the contrary contained herein, Tenant shall be charged for the electricity consumed by it for the Demised Premises based upon the then current Service Classification, billed by the Utility Company servicing the property, which is commensurate with Tenant's level of usage (including all taxes, charges, terms, rates and other fees associated with Landlord providing electrical service), plus fifteen percent (15%). Such taxes, charges, terms and rates to Landlord in connection with the supply of electric current to the Building of which the Demised Premises are a part, will be used in the calculation of the Tenant billing. Anything contained in subparagraph C hereof to the contrary notwithstanding, Tenant, within twenty (20) days after receipt of the determination of Landlord's electric consultant, may contest, at Tenant's sole cost and expense, the results thereof by retaining a reputable electrical engineer or consultant to make a survey of the electrical equipment, usage and powerload to ascertain the electric current consumption and demand in the Demised Premises on an annual basis, and to calculate the annual rent increase resulting therefrom as hereinabove provided. Tenant shall furnish Landlord with a copy of the report and calculation of the survey conducted by tenant's electrical engineer or consultant, by certified or registered mail, return receipt requested, within ten (10) days of Tenant's receipt thereof. In the event of a discrepancy between Landlord's and Tenant's determination of the increase in annual rent resulting from Tenant's electric equipment, usage and powerload, the Landlord and Tenant shall cause their respective electrical engineers or consultants to confer and resolve the discrepancy within thirty (30) days after Landlord's receipt of Tenant's report. If the respective electrical engineers and consultants shall be unable to reach agreement within sixty (60) days of Landlord's receipt of Tenant's report, the two engineers or consultants shall designate a third engineer or consultant to make the determination in accordance with the provisions of this electric rider, and the determination of said third engineer or consultant shall be binding and conclusive on the parties hereto. If the parties' respective engineers or consultants shall be unable to agree upon the designation of a third engineer or consultant by the eightieth day after Landlord's receipt of Tenant's report, either party hereto may request the American Arbitration Association to designate such third engineer or consultant, whose determination shall be binding and conclusive upon the parties hereto. The costs and expenses of any such third engineer or consultant shall be paid by the party whose determination of the increase to annual rent due to Tenant's electric equipment, usage and powerload was at the greatest variance from the determination of the third engineer or consultant. Pending the resolution of any contest pursuant to the terms hereof, Tenant shall pay the increase in the annual rent as provided pursuant to the determination of Landlord's engineer or consultant, and upon the resolution of any such contest, the increase to annual rent shall be adjusted accordingly, with arrears paid to Landlord, or a refund or credit allowed to Tenant, as the case may be, within thirty (30) days of the date of the determination of the third engineer or consultant.
