STANDARD RIDER PROVISIONS

1. OS TENANT SPACE.

1.1 OS Tenant Space. Upon and subject to the terms and conditions of this Rider, the Lease is hereby modified to reflect that Landlord does hereby lease, demise and let unto Tenant and Tenant does hereby lease from Landlord the OS Tenant Space, to have and to hold for the OS Rider Term.

1.2 Condition of OS Tenant Space. Tenant agrees that, subject to Landlord’s completion of Landlord’s OS Installations, Tenant shall be deemed to have accepted the OS Tenant Space in its “AS IS, WHERE IS” condition on the OS Commencement Date. Except for Landlord’s OS Installations, Landlord shall have no obligation to perform any work in the OS Tenant Space (including, without limitation, demolition of any improvements existing therein or construction of any tenant finish-work or other improvements therein), and Landlord shall not be obligated to reimburse Tenant or provide an allowance for any costs related to the demolition or construction of improvements therein. Tenant acknowledges that, except as expressly set forth herein, no representation or warranty (express or implied) has been made by Landlord as to the condition of the OS Tenant Space or its suitability or fitness for Tenant’s intended purpose.

1.3 Delivery of OS Tenant Space. Landlord shall use commercially reasonable efforts to cause Landlord’s OS Installations to be completed prior to the OS Commencement Date. In the event, however, that Landlord’s OS Installations have not been completed by the OS Commencement Date, Landlord shall not be deemed in default hereunder, provided that Landlord is working diligently using commercially reasonable efforts after the OS Commencement Date to complete the installation of Landlord’s OS Installations.

1.4 Rights Reserved to Landlord. Landlord reserves the right to relocate the OS Tenant Space to some other space of Landlord’s choosing of approximately the same dimensions and size within the Building without effecting an eviction or disturbance of Tenant’s use or possession or giving rise to any claim for setoffs or abatement of OS Base Rent due under this Rider; provided, however, that if Landlord exercises Landlord’s option to remove and relocate Tenant in the New OS Tenant Space, then Tenant shall be required to pay the same per square foot rates of OS Base Rent, as is represented in this Rider. Nothing herein contained shall be construed to relieve Tenant, or imply that Tenant is relieved, of the liability for or obligation to pay any additional rental due by reason of any of the other provisions of this Rider, which provisions shall be applied to the New OS Tenant Space. Tenant agrees that Landlord’s exercise of Landlord’s option to remove and relocate Tenant shall not terminate the Lease or this Rider or release Tenant, in whole or in part, from Tenant’s obligation to pay the rental and perform the covenants and agreements hereunder for the full OS Rider Term. In the event of any such relocation, this Rider shall continue in full force and effect with no change in the terms, covenants or conditions hereof other than the substitution of the New OS Tenant Space for the OS Tenant Space. Upon request from Landlord, Tenant shall execute an amendment to this Rider reflecting the aforesaid change. Landlord agrees that the New OS Tenant Space shall be decorated by Landlord at Landlord’s sole cost and expense. Landlord shall have the right, in Landlord’s sole discretion, to use such decorations and materials from the OS Tenant Space, or other materials, so that the New OS Tenant Space shall be comparable in its interior design and decoration to the OS Tenant Space. Landlord shall use commercially reasonable efforts to effect such relocation or reconfiguration in a manner that minimizes to the extent practical any interruption or adverse effect on Tenant’s operations in the OS Tenant Space. Landlord shall provide Tenant no less than thirty (30) calendar days’ prior notice of all such relocations or reconfigurations. Following receipt of such notice, if said relocation or reconfiguration requires the movement of any of Tenant’s equipment or property, Tenant shall relocate Tenant’s equipment or property to the new location within the Building which is designated by Landlord and reasonably acceptable to Tenant. Landlord shall reimburse Tenant for all of the reasonable, out-of-pocket costs actually incurred by Tenant in so relocating its equipment or property. Tenant’s right to reimbursement to the extent provided above in this Section 1.4 shall be Tenant’s sole remedy in the event Landlord elects to relocate the OS Tenant Space, and Tenant shall not be entitled to any additional compensation or damages for loss of, or interference with, Tenant’s business or use or access of all or any part of the OS Tenant Space resulting from such relocation.

Landlord shall have no responsibility to provide Back-Up Power for use in the OS Tenant Space.

3.5.2 Electricity Provided. Tenant’s electricity consumption for the OS Tenant Space is included in the OS Base Rent set forth in Item 6 of the Basic Rider Information.

any use other than the OS Permitted Use, in addition to all other rights and remedies given Landlord hereunder or by law or in equity, the Tenant shall be required to pay monthly, as Additional Rent, an amount equal to the product of the number of rentable square feet in the OS Tenant Space multiplied by the monthly base rental rate then being quoted by Landlord to prospective tenants for space in the Building to be used as a datacenter or a telecommunications facility.

(2) Water at those points of supply provided for general use.

4.4 Interruption of Services. Landlord shall not be liable or responsible to Tenant for any loss, damage or expense of any type which Tenant may sustain or incur if the quantity or character of the utility provided electric service to the OS Tenant Space is changed, is no longer available, or is no longer suitable for Tenant’s requirements. No interruption or malfunction of any electrical or other service (including, without limitation, HVAC) to the OS Tenant Space (or to any other portion of the Building or Property) shall, in any event, (i) constitute an eviction or disturbance of Tenant’s use and possession of the OS Tenant Space, (ii) constitute a breach by Landlord of any of Landlord’s obligations under the Lease or this Rider, (iii) render Landlord liable for damages of any type or entitle Tenant to be relieved from any of Tenant’s obligations under the Lease or this Rider (including the obligation to pay OS Base Rent, Additional Rent, or other charges), (iv) grant Tenant any right of setoff or recoupment, (v) provide Tenant with any right to terminate the Lease or this Rider, or (vi) make Landlord liable for any injury to or

In the event of any interruption, however, Landlord shall employ commercially reasonable efforts to restore such service or cause the same to be restored in any circumstances in which such restoration is within the reasonable control of Landlord.

5. MAINTENANCE; ALTERATIONS.

5.1 Landlord’s Maintenance. Aside from Landlord’s OS Repair Obligations, Landlord shall have no repair and maintenance obligations in connection with the OS Tenant Space. Subject to Section 6 below, Landlord shall be responsible for Landlord’s OS Repair Obligations, all as necessary to maintain such elements of the Building and the OS Tenant Space in a first class, clean, and safe condition.

If Tenant fails to perform its covenants of maintenance and repair hereunder, or if Tenant or any of Tenant’s technicians or representatives physically damages the OS Tenant Space, the personal property of any other tenant or anything else in the Building or the Property, Landlord may, but shall not be obligated to, perform all necessary or appropriate maintenance and repair, and any amounts expended by Landlord in connection therewith, plus an administrative charge of ten percent (10%), shall be reimbursed by Tenant to Landlord as Additional Rent upon demand.

5.3 Alterations; Fixtures.

All materials introduced into the OS Tenant Space and/or the Property must be consented to in advance by Landlord. All cable installed in the OS Tenant Space and/or otherwise at the Property must be plenum rated. If such prior written consent of Landlord is granted, the work in such connection shall be at Tenant’s expense by workmen and contractors approved in advance in writing by Landlord and in a manner and upon terms and conditions and at times that are reasonably satisfactory to and reasonably approved in advance in writing by Landlord. In any instance where Landlord grants such consent, Landlord may grant such consent contingent and conditioned upon Tenant’s contractors, laborers, materialmen and others furnishing labor or materials for Tenant’s job working in harmony and not interfering with any labor utilized by Landlord, Landlord’s contractors or mechanics or by any other tenant or such other tenant’s contractors or mechanics; and if at any time such entry by one (1) or more persons furnishing labor or materials for Tenant’s work shall cause disharmony or interference for any reason whatsoever without regard to fault, the consent granted by Landlord to Tenant may be withdrawn at any time upon written notice to Tenant.

5.3.2 Tenant shall remove Tenant’s trade fixtures, office supplies and movable office furniture and equipment not attached to the Building prior to the expiration of the OS Rider Term. All other property in the OS Tenant Space and any alteration or addition to the OS Tenant Space (including wall-to-wall carpeting, paneling or other wall covering) and any other article attached or affixed to the floor, wall or ceiling of the OS Tenant Space or the Building shall, upon such expiration or termination, become the property of Landlord, shall be surrendered in good condition, normal wear and tear excepted, and shall remain upon, and be surrendered with, the OS Tenant Space or the Building, as applicable, as part thereof at the expiration of the OS Rider Term, Tenant hereby waiving all rights to any payment or compensation therefor; provided, however, that Tenant shall, in any event, remove all cabling,

-4-

including, without limitation, telephone and computer cabling, installed in the OS Tenant Space and/or the risers of the Building in connection with Tenant’s lease of the OS Tenant Space. If, however, Landlord so requests in writing, Tenant will, prior to the termination of this Rider, remove in a good and workmanlike manner any and all alterations, additions, fixtures, equipment and property placed or installed by Tenant in or about the OS Tenant Space and/or the Building, including, without limitation, above ceiling alterations, and will repair any damage occasioned by such removal.
