Tenant hereby agrees to indemnify, defend and hold harmless Landlord from any and all claims and damages in any way relating to the construction, maintenance, operation of any Storage Tanks on the Leased Premises, and if applicable, the Storage Tank Removal (as defined below), including claims and damages from subsurface and groundwater conditions relating to any of the construction, maintenance, operation, and if applicable, the Storage Tank Removal. Such indemnity shall survive the termination or expiration of the Lease.

(g) At all times, Tenant shall cause the Storage Tanks, at Tenant’s sole cost and expense, to be maintained and operated in accordance with all applicable Laws and all Legal Requirements, but not limited to, making any changes thereto as may be required from time to time by such applicable Laws, Legal Requirements, ordinances or other requirements. Tenant shall maintain complete and accurate records of all maintenance and all testing of the Storage Tanks, and each portion thereof, and make such records available upon ten (10) days’ prior written notice to Landlord. Additionally, Tenant shall furnish Landlord with copies of all certification and inspection reports obtained by Tenant for any purpose in connection with the Storage Tanks, including but not limited to as required for insurance purposes, within thirty (30) days of Tenant’s receipt of such certification and inspection reports

(h) Prior to the end of the Term (but not more than sixty (60) days prior thereto), Tenant shall furnish Landlord with an environmental report (which report shall be customary at the time it is furnished) reasonably acceptable to Landlord which report must indicate that the Storage Tanks are not leaking, or, if any leakage is detected, that areas in which the Storage Tanks are located are not contaminated above reportable levels by any leakage from the Storage Tanks and to the extent such report reveals that there are any Hazardous Substance in such areas, Tenant shall be solely responsible, at Tenant’s sold cost and expense, for removing and remediating such areas in accordance with applicable Legal Requirements and in a manner reasonably acceptable to Landlord (including repairing any damage to the Leased Premises in connection with the Storage Tank Removal).

(i) All costs and expenses incurred by Landlord relating to the review, approval, monitoring or implementation and monitoring of the Storage Tanks shall be paid for by Tenant promptly upon demand, and in any event within ten (10) Business Days of written demand therefor.

(a) Subject to the provisions of Section 9(b) hereof, Tenant shall not, directly or indirectly, create or permit to be created or to remain and shall promptly after notice thereof discharge or remove, any lien, levy or encumbrance on the Leased Premises or on any Rent or any other sums payable by Tenant under this Lease, other than the Permitted Encumbrances and any mortgage, lien, encumbrance or other charge created by or resulting solely from any act or omission of Landlord. In the event of attachment of a mechanic’s lien or other lien for labor, services or materials furnished to Tenant or to anyone holding or occupying the Leased Premises through or under Tenant, Tenant shall immediately notify Landlord and Lender of such lien or other action of which Tenant has or reasonably should have knowledge and which affects title to the Leased Premises or any part thereof, and shall cause the same to be removed within twenty (20) days (or such additional time as Landlord and Lender may consent to in writing) of notice of such lien. If Tenant shall fail to remove such lien within said time period, Landlord or Lender may take such action as Landlord or Lender, as applicable, deem necessary to remove the same and the entire cost thereof shall be immediately due and payable by Tenant to Landlord or Lender, as applicable, and such amount shall bear interest at the Default Rate.

(b) Tenant shall execute, deliver and record, file or register all such instruments as may be required or permitted by any present or future Law in order to evidence the respective interests of Landlord and Tenant in the Leased Premises, and shall cause a memorandum of this Lease (or, if such a memorandum cannot be recorded, this Lease), and any supplement hereto or thereto, to be recorded in such manner and in such places as may be required or permitted by any present or future Law in order to protect the validity and priority of this Lease.

(a) Tenant shall at all times maintain the Leased Premises and the Equipment in Good Condition and Repair and in compliance with all Legal Requirements. Tenant shall take every action reasonably necessary or appropriate for the preservation and safety of the Leased Premises. Tenant shall promptly make all Alterations of every kind and nature, whether foreseen or unforeseen, which may be required to comply with the foregoing requirements of this Section 11(a). Landlord shall not be required to make any Alteration, whether foreseen or unforeseen, or to maintain any of the Leased Premises. Tenant hereby expressly waives any right which may be provided for in any Law now or hereafter in effect to make Alterations at the expense of Landlord or, to require Landlord to make Alterations. Any Alteration made by Tenant pursuant to this Section 11 shall be made in conformity with the provisions of Section 12.

(b) If any Improvement hereafter constructed, shall (i) encroach upon any setback or any property, street or right-of-way adjoining the Leased Premises, (ii) violate the provisions of any restrictive covenant affecting the Leased Premises, (iii) hinder or obstruct any easement or right-of-way to which the Leased Premises is subject or (iv) impair the rights of others in, to or under any of the foregoing, Tenant shall, promptly after receiving notice thereof, either (A) obtain from all necessary parties waivers or settlements of all claims, liabilities and damages resulting from each such encroachment, violation, hindrance, obstruction or impairment, whether the same shall affect Landlord, Tenant or both, or (B) take such reasonable action as shall be necessary to remove all such encroachments, hindrances or obstructions and to end all such violations or impairments, including, if necessary, making Alterations. Tenant acknowledges and agrees that Landlord shall have no obligation to correct any of the foregoing conditions to the extent that any one or more of them exist prior to the Commencement Date and that Tenant shall continue to be bound by the terms of this Lease regardless of the existence of any such pre-existing conditions.

(c) Landlord and Tenant acknowledge that it is Tenant’s responsibility to keep the Leased Premises in Good Condition and Repair and in compliance with all Legal Requirements. Landlord shall not perform any repairs, modifications or improvements to the Leased Premises, unless (i) Tenant has failed to take the necessary actions to maintain the Leased Premises in Good Condition and Repair, after fifteen (15) days advance written notice from Landlord, or (ii) in Landlord’s reasonable judgment such actions are required on an emergency basis to protect life or property and Tenant is not responding to such emergency; provided, however, that under no circumstances shall Landlord be obligated to perform any repairs, modifications or improvements to the Leased Premises or keep the Leased Premises in Good Condition and Repair.

(b) Tenant shall have the right, without having obtained the prior written consent of Landlord and provided that no Event of Default then exists, (i) to make any improvements, alterations or modifications to the Leased Premises the cost of which is less than Two Hundred and Fifty Thousand Dollars ($250,000) (so long as such improvements do not

devalue the Leased Premises or increase Landlord’s obligations or liability during or after the Term in any way), (ii) to make non-structural Alterations which are reasonably required or desirable for the operation of Tenant’s business in the Leased Premises and which are not visible from the exterior of the Leased Premises, or (iii) to install or replace Equipment in the Improvements or accessions to the Equipment. If Tenant desires to make Alterations to the Leased Premises which are not covered by clauses (i), (ii) or (iii) above, the prior written approval of Landlord shall be required which shall not be unreasonably withheld, delayed or conditioned. Tenant shall not construct upon the Land any additional buildings without having first obtained the prior written consent of Landlord which shall not be unreasonably withheld, delayed or conditioned. Landlord and Tenant acknowledge that Tenant is in the business of providing telecommunications and collocation services to its customers. Over the Term of this Lease it is likely that, due to technological innovations, the nature of these services and/or the equipment or facilities required to perform these services in an optimal manner may change. Landlord acknowledges that any Alterations required to accommodate such changes in Tenant’s business shall be deemed reasonable so long as they do not impair the value of the Leased Premises. An Alteration will not be deemed to impair the value of the Leased Premises, if the Alteration can be removed at the end of the Term, and the Leased Premises can be reasonably restored to their condition prior to such Alteration.

(c) If Tenant makes any Alterations pursuant to this Section 12 or as required by Sections 11 or 16 (such Alterations and actions being hereinafter collectively referred to as “Work”), then prior to commencing any Work, Tenant shall (i) submit to Landlord, for Landlord’s written approval, where required, detailed plans and specifications therefor in form satisfactory to Landlord, (ii) if such Alterations require a filing with any Governmental Authority or require the consent of such authority, then such plans and specifications shall (A) be prepared and certified by a registered architect or licensed engineer, and (B) comply with all Laws to the extent necessary for such governmental filing or consent, (iii) at its expense, obtain all required permits, approvals and certificates, (iv) furnish to Landlord duplicate original policies or certificates of insurance evidencing worker’s compensation coverage (covering all persons to be employed by Tenant, and all contractors and subcontractors supplying materials or performing work in connection with such Alterations) and comprehensive public liability (including property damage coverage) insurance, comprehensive form automobile liability insurance and Builder’s Risk coverage (issued on a completed value basis) all in such form, with such companies, for such periods and in such amounts as Landlord may require, naming Landlord and its employees and agents as additional insureds. All Alterations shall be performed by Tenant at Tenant’s sole cost and expense (A) in a good and workmanlike manner using materials of first class quality, (B) in compliance with all Laws, and (C) in accordance with the plans and specifications previously approved by Landlord. Tenant shall at its cost and expense obtain all approvals, consents and permits from every Governmental Authority having or claiming jurisdiction prior to, during and upon completion of such Alterations. If any such Work involves the replacement of Equipment or parts thereto installed on the Leased Premises, and except in instances where such Equipment is obsolete, all replacement Equipment or parts shall have a functional value and useful life equal to the functional value and useful life of the Equipment being replaced immediately prior to the occurrence of the event which required its replacement (assuming such replaced Equipment was then in the condition required by this

Lease). Tenant shall promptly reimburse Landlord, as Additional Rent and upon demand, for any and all costs and expenses incurred by Landlord in connection with Landlord’s review of Tenant’s plans and specifications for any such Alteration, not to exceed Fifteen Hundred Dollars ($1500).

(d) Landlord agrees to respond to any written request for approval of all Tenant’s plans and specifications for any Alterations (“Tenant’s Plans”) within ten (10) Business Days after Tenant’s request, provided Tenant’s Plans comply in all material respects with the requirements of this Section 12. In addition, Landlord agrees to respond to any resubmission of Tenant’s Plans within five (5) Business Days after written resubmission. If Landlord either fails to approve or disapprove any Tenant’s Plans on or before the end of the applicable review period set forth herein, such Tenant’s Plans or revisions thereto shall be deemed to be approved by Landlord. Tenant may at the time that any Tenant’s Plans are submitted to Landlord also request that Landlord indicate whether or not the Alterations described in such Tenant’s Plans will be required to be removed at the end of the Term or upon the earlier termination of this Lease. In the event that any Alterations or new equipment are in the category that do not require Landlord’s consent for the construction or installation thereof, Tenant may remove such items at the end of the Term, at Tenant’s election.

(e) Upon completion of any Alterations and any work pursuant to this Section 12, Tenant, at its expense, shall promptly obtain certificates of final approval of such Alterations as may be required by any Governmental Authority, and shall furnish Landlord with copies thereof, together with “as built” plans and specifications for such Alterations prepared on an Autocad Computer Assisted Drafting and Design System (or such other system or medium as Landlord may accept).

(f) Tenant shall not be required to remove the following at the end of the Term or earlier termination of this Lease: (i) Alterations which Landlord has previously agreed to in writing or which otherwise are permitted under the terms of the Lease, and (ii) Alterations which are substantially consistent in form or function to the Improvements existing as of the Rent Commencement Date. Notwithstanding anything to the contrary, Tenant shall not be permitted to remove any improvements and equipment existing on the Leased Premises as of the Rent Commencement Date or any new improvements or equipment added subsequent to the date hereof which are necessary for the operation of the Leased Premises (except to the extent replaced or removed prior to the expiration of the Term or earlier termination of this Lease in accordance with the provisions hereof) and all Alterations remaining on the Leased Premises at the end of the Term of this Lease shall become the property of Landlord at such time.

required for the conduct of Tenant’s business on the Leased Premises. All work done in connection with the items described in clauses (i), (ii) and (iii) above shall be deemed Alterations and shall be subject Sections 12(b)-12(e) above but shall not require any prior consent from the Landlord.

(a) Tenant shall pay, protect, indemnify, defend, save and hold harmless Landlord and all other Persons described in Section 29 (each an “Indemnitee”) from and against any and all liabilities, losses, damages (including punitive damages), penalties, Costs (including reasonable attorneys’ fees and costs), causes of action, suits, claims, demands or judgments of any nature whatsoever arising from (i) any matter pertaining to the ownership, leasing, use, non-use, occupancy, operation, management, condition, design, construction, maintenance, repair or restoration of the Leased Premises and Tenant’s business operations thereon, (ii) any casualty in any manner arising from the Leased Premises, whether or not Indemnitee has or should have knowledge or notice of any defect or condition causing or contributing to said casualty, (iii) any violation by Tenant of any provision of this Lease, any contract or agreement to which Tenant is a party, any Legal Requirement or any Permitted Encumbrance, or (iv) any alleged, threatened or actual Environmental Violation, including, with out limitation, (A) liability for response costs and for costs of removal and remedial action incurred by the United States Government, any state or local governmental unit or any other Person, or damages from injury to or destruction or loss of natural resources, including the reasonable costs of assessing such injury, destruction or loss, incurred pursuant to Section 107 of CERCLA, or any successor section or act or provision of any similar state or local Law, (B) liability for costs and expenses of abatement, correction or clean-up, fines, damages, response costs or penalties which arise from the provisions of any of the other Environmental Laws and (C) liability for personal injury or property damage arising under any statutory or common-law tort theory, including damages assessed for the maintenance of a public or private nuisance or for carrying on of a dangerous activity. Notwithstanding the foregoing, the indemnification contained in this Section 14(a) shall not cover any of the foregoing that result from the gross negligence or willful misconduct of Landlord or the breach by Landlord of any provision of this Lease.

(b) In case any action or proceeding is brought against any Indemnitee by reason of any such claim, (i) such Indemnitee shall notify Tenant to resist or defend such action or proceeding by retaining counsel reasonably satisfactory to such Indemnitee, and such Indemnitee will cooperate, at no cost to such Indemnitee, and assist in the defense of such action or proceeding if reasonably requested to do so by Tenant, and (ii) Tenant may, except in the event of a conflict of interest or a bona fide dispute between Tenant and any such Indemnitee or during the continuance of an Event of Default, retain its own counsel and defend such action (it being understood that Landlord may employ counsel of its choice to monitor the defense of any such action, the reasonable cost of which shall be paid by Tenant in the event of a conflict of interest, a bona fide dispute between Landlord and Tenant or during the continuance of an Event of Default). In the event of a conflict of interest or dispute or during the continuance of an Event of Default or Tenant’s request that Landlord handle its own defense, Landlord shall have the right to select counsel, and the cost of such counsel shall be paid by

Tenant. Notwithstanding the foregoing, Tenant shall not enter into any settlement which would affect Landlord or the Leased Premises without Landlord’s prior written consent which may be withheld in its sole and absolute discretion.

(c) The obligations of Tenant under this Section 14 shall survive any termination, expiration or rejection in bankruptcy of this Lease with respect to matters that occurred or existed prior to such termination, expiration or rejection.

(a) Tenant shall maintain the following insurance on or in connection with the Leased Premises:

(i) Insurance against physical loss or damage to the Improvements and Equipment as provided under a standard “All Risk” or “Special Perils” property policy including, but not limited to, flood (to the extent that the Leased Premises is in a flood zone) for 100% of the replacement value of the Improvements and Equipment.

(iv) Comprehensive Boiler and Machinery Insurance on any of the Equipment or any other equipment on or in the Leased Premises in an amount not less than $4,000,000 per accident for damage to property.

The perils covered by this policy shall be the same as those accepted on the Leased Premises including flood, earthquake and earth movement.

(vi) During any period in which any Alterations at the Leased Premises are being undertaken, Tenant will obtain commercial general liability insurance including contractual liability, in the amount of $1,000,000 primary and $10,000,000 excess liability in the aggregate (the policy shall provide coverage on an occurrence basis against claims for personal injury, bodily injury and death or property damage occurring on, in or about the Leased Premises and the adjoining streets, sidewalks and passageways. In addition, Tenant shall require all contractors and subcontractors, architects and engineers to provide appropriate insurance coverage), including Builder’s risk insurance on a completed value basis protecting against “all risks” of physical loss, including collapse during construction, water damage, flood, earthquake and transit coverage (coverage should be on a non-reporting form, covering the total value of work performed and equipment, supplies and materials furnished (with an appropriate limit for soft costs in the case of construction) with deductibles approved by Landlord).

(xi) Such other insurance (or other terms with respect to any insurance required pursuant to this Section 15, including, without limitation, amounts of coverage, deductibles, form of mortgagee clause) on or in connection with the Leased Premises as Landlord may reasonably require, which at the time is usual and commonly obtained in connection with properties similar in type of building size, use and location to the Leased Premises.

(b) The insurance required by Section 15(a) shall be written by companies which have a Best’s rating of A with a financial size of Class IX or above or a comparable claims paying ability assigned by Standard & Poor’s Corporation or equivalent rating agency approved by Landlord and are admitted in, and approved to write insurance policies by, the State Insurance Department for the state in which the Leased Premises are located. The insurance policies (i) shall be for such terms as Landlord may reasonably approve, (ii) shall be primary and without right of contribution of any other insurance carried by or on behalf of Landlord (if any), and (iii) shall be in amounts sufficient at all times to satisfy any coinsurance requirements thereof.

The insurance referred to in Sections 15(a)(ii) and 15(a)(viii) shall name Landlord as an additional insured.

In addition, Tenant hereby grants to the Lender the same rights as Landlord under this Section 15 and Section 16. In addition to the foregoing, if required by Lender, the insurance referred to in Sections 15(a)(ii) and 15(a)(viii) shall also name the Lender as an additional insured under such policies.

(c) Each policy required by any provision of Section 15(a), except clause (iii) thereof, shall provide that it may not be cancelled on any renewal date except after thirty (30) days’ prior notice to Landlord. Each such policy shall also provide that any loss otherwise payable thereunder shall be payable notwithstanding any change in title to or ownership of the Leased Premises and, to the extent available, shall provide that any loss otherwise payable thereunder shall be payable notwithstanding (i) any act or omission of Landlord or Tenant which might, absent such provision, result in a forfeiture of all or a part of such insurance payment, and (ii) the occupation or use of the Leased Premises for purposes more hazardous than those permitted by the provisions of such policy.

(d) Tenant shall pay as they become due all premiums for the insurance required by Section 15(a), shall renew or replace each policy and upon written request deliver to Landlord evidence of timely payment of the full premium therefor or installment then due and shall promptly deliver to Landlord all original certificates of insurance.

(e) Anything in this Section 15 to the contrary notwithstanding, any insurance which Tenant is required to obtain pursuant to Section 15(a) may be carried under a “blanket” or umbrella policy or policies covering other properties or liabilities of Tenant, provided that such “blanket” or umbrella policy or policies otherwise comply with the provisions of this Section 15 and provided further that Tenant shall provide to Landlord a Statement of Values which shall be reviewed annually and amended as necessary based on Replacement Cost Valuations. Upon written request, a certified copy of each such “blanket” or umbrella policy shall promptly be delivered to Landlord.

(f) Tenant shall have the replacement cost and insurable value of the Improvements and Equipment determined from time to time as required by the replacement cost and agreed amount endorsements and shall deliver to Landlord the new replacement cost and agreed amount endorsement or certificate evidencing such endorsement promptly upon Tenant’s receipt thereof.

(g) Tenant shall promptly comply with and conform to (i) all provisions of each insurance policy required by this Section 15 and (ii) all requirements of the insurers thereunder applicable to Landlord, Tenant or the Leased Premises or to the use, manner of use, occupancy, possession, operation, maintenance, alteration or repair of the Leased Premises, even if such compliance necessitates Alterations or results in interference with the use or enjoyment of the Leased Premises.

(h) Tenant shall not carry separate insurance concurrent in form or contributing in the event of a Casualty with that required in this Section 15 unless (i) Landlord are included therein as named insureds, with loss payable as provided herein, and (ii) such separate insurance complies with the other provisions of this Section 15. Tenant shall immediately notify Landlord of such separate insurance and shall deliver to Landlord the certified copies of such certificates of insurance evidencing such coverage.

(i) All policies shall contain effective waivers by the carrier against all claims for insurance premiums against Landlord and shall contain full waivers of subrogation against the Landlord.

(j) All proceeds of any insurance required under Section 15(a) shall be payable as follows:

(i) Proceeds payable under clauses (ii), (iii) and (iv) of Section 15(a) and proceeds attributable to the general liability coverage of Builder’s Risk insurance under clause (vi) of Section 15(a) shall be payable to the Person entitled to receive such proceeds.

(ii) Proceeds of insurance required under clause (i) and (vii) - (x) of Section 15(a) and proceeds attributable to Builder’s Risk insurance (other than its general liability coverage provisions) under clause (vi) of Section 15(a) shall be payable to Landlord and applied as set forth in Section 17 or, if applicable, Section 18. Tenant shall apply the Net Award to restoration of the Leased Premises in accordance with the applicable provisions of this Lease unless a Termination Event shall have occurred and Tenant has given a Termination Notice in which case the Landlord shall be entitled to keep the Net Award.

(iii) Proceeds of insurance required under clause (v) of Section 15(a) shall be payable to Landlord, and any amounts so received shall be applied against Basic Rent as the same shall become due and owing.

(a) If any Casualty to the Leased Premises occurs the insurance proceeds for which are reasonably estimated by Tenant to be equal to or in excess of One Million Dollars ($1,000,000), Tenant shall give Landlord prompt notice thereof. So long as no Event of Default exists, Tenant is hereby authorized to adjust, collect and compromise all claims under any of the insurance policies required by Section 15(a) (except public liability insurance claims payable to a Person other than Tenant, or Landlord) and to execute and deliver on behalf of Landlord all necessary proofs of loss, receipts, vouchers and releases required by the insurers and Landlord shall have the right to join with Tenant therein. Notwithstanding the foregoing, any final adjustment, settlement or compromise of any such claim that is in excess of One Million Dollars ($1,000,000) shall be subject to the prior written approval of Landlord. If an Event of Default exists, Tenant shall not be entitled to adjust, collect or compromise any such claim or to participate with Landlord in any adjustment, collection and compromise of the Net Award payable in connection with a Casualty. Tenant agrees to sign, upon the request of Landlord, all such proofs of loss, receipts, vouchers and releases. Each insurer is hereby authorized and directed to make payment under said policies, excluding return of unearned premiums, directly to Landlord and Tenant jointly, and Tenant hereby appoints Landlord as Tenant’s attorney-in-fact to endorse any draft therefor.

(b) Tenant, promptly upon receiving a Condemnation Notice, shall notify Landlord thereof. Landlord shall be authorized to collect, settle and compromise the amount of any Net Award and, provided that so long as an Event of Default does not exist, Tenant shall be entitled to participate with Landlord in any Condemnation proceeding or negotiations under threat thereof or to contest the Condemnation or the amount of the Net Award therefor. Subject to the provisions of this Section 16(b), Tenant hereby irrevocably assigns to Landlord any award or payment to which Tenant is or may be entitled by reason of any Condemnation, whether the same shall be paid or payable for Tenant’s leasehold interest hereunder or otherwise; but nothing in this Lease shall impair Tenant’s right to any award or payment on account of Tenant’s trade fixtures, equipment or other tangible property which is not part of the Equipment, moving expenses or loss of business, if available, to the extent that and so long as (i) Tenant shall have the right to make, and does make, a separate claim therefor against the condemnor and (ii) such claim does not in any way reduce either the amount of the award otherwise payable to Landlord for the Condemnation of Landlord’s fee interest in the Leased Premises or the amount of the award (if any) otherwise payable for the Condemnation of Tenant’s leasehold interest hereunder.

(c) If any Partial Casualty (whether or not insured against) or Partial Condemnation shall occur to the Leased Premises, this Lease shall continue, notwithstanding such event, and the Basic Rent payable hereunder shall be appropriately adjusted to reflect any reduction in the net rentable area of the Improvements that is unavailable for Tenant’s use and occupancy if the lost use of such space adversely affects Tenant’s ability to operate its business

in a material manner, as a result of such Partial Casualty or Partial Condemnation, but only to the extent Landlord receives the insurance proceeds under Section 15(a)(v) to cover the lost Basic Rent and if any such insurance proceeds relating to lost Basic Rent (or lost profits but only to the extent of Basic Rent due and payable) are paid to Tenant, Tenant shall pay such sums to Landlord, and only for so long as Tenant’s use and occupancy is adversely affected. Except as provided in the preceding sentence, Tenant’s Basic Rent shall not abate or be reduced during Tenant’s restoration of the Improvements. Promptly after such Partial Casualty or Partial Condemnation, Tenant, as required in Section 11(a), shall commence and diligently continue to restore the Leased Premises as nearly as possible to their value, condition and character immediately prior to such event (assuming the Leased Premises to have been in the condition required by this Lease), and so long as no Event of Default exists, any Net Award up to and including One Million Dollars ($1,000,000) shall be paid by Landlord directly to Tenant for the purpose of paying the cost of such restoration, provided, that Tenant shall pay Landlord the amount of any shortfall to the extent the Net Award is insufficient to cover the cost of the restoration or Tenant shall provide Landlord with adequate security to secure the payment of such shortfall as and when required by Landlord. Any Net Award in excess of One Million Dollars ($1,000,000) shall (unless such Casualty and Condemnation resulting in the Net Award is a Termination Event) be made available by Landlord to Tenant for the restoration of the Leased Premises pursuant to and in accordance with and subject to the provisions of Section 18(b) hereof.

(a) If (i) all of the Leased Premises shall be taken by a Taking, (ii) all of the Leased Premises shall be substantially damaged or destroyed by a Casualty, (iii) any portion of the Leased Premises shall be taken by a Taking and the remaining portion of the Leased Premises is unsuitable or uneconomical for the continuation of Tenant’s business therein, or (iv) any portion of the Leased Premises is destroyed or damaged by a Casualty and the estimated time to repair or replace the Leased Premises is in excess of one (1) year, as reasonably estimated by Landlord, or under applicable law the Leased Premises cannot be rebuilt to a condition that is suitable and economical for the operation of Tenant’s business therein (each of the events described in the above clauses (i), (ii), (iii) and (iv) shall hereinafter be referred to as a “Termination Event”), then Tenant shall have the option, within thirty (30) days after Tenant receives a Condemnation Notice, or within thirty (30) days after the Casualty, as the case may be, to give to Landlord written notice (a “Termination Notice”) in the form described in Section 17(b) of the Tenant’s election to terminate this Lease.

(b) A Termination Notice shall contain notice of Tenant’s intention to terminate this Lease on the first Basic Rent Payment Date occurring after the date of such Termination Notice.

(a) In the event that the Lease is not terminated as a result of any Condemnation or Casualty as provided in Section 17 above, Landlord shall hold any Net Award

(iv) each request for disbursement shall be accompanied by a certificate of Tenant, signed by an officer of Tenant, describing the work for which payment is requested, stating the cost incurred in connection therewith, stating that Tenant has not previously received payment for such work and, upon completion of the work, also stating that the work has been fully completed and complies with the applicable requirements of this Lease;

(v) Landlord may retain ten percent (10%) of the Restoration Fund until the restoration is fully completed;

(vi) the Restoration Fund shall not be commingled with Landlord’s other funds and shall bear interest at a rate agreed to by Landlord and Tenant;

(b) Prior to commencement of restoration and at any time during restoration, if the estimated cost of completing the restoration work free and clear of all liens, as reasonably determined by Landlord, exceeds the amount of the Net Award available for such restoration, the amount of such excess shall, within ten (10) days following written request by Landlord, be paid by Tenant to Landlord to be added to the Restoration Fund or Tenant shall provide Landlord with reasonable adequate security to secure the payment of such excess as and when required. Any sum so added by Tenant which remains in the Restoration Fund upon completion of restoration shall be refunded to Tenant. For purposes of determining the source of funds with respect to the disposition of funds remaining after the completion of restoration, the Net Award shall be deemed to be disbursed prior to any amount added by Tenant.

(c) If any sum remains in the Restoration Fund after completion of the restoration and any refund to Tenant pursuant to Section 18(b), such sum shall be retained by Landlord.

(a) Tenant shall have the right, upon fifteen (15) days prior written notice to Landlord, with no consent of Landlord being required or necessary (“Preapproved Assignment”), to assign this Lease by operation of law or otherwise to any of the following Persons (each a “Preapproved Assignee”): (i) an affiliate, subsidiary, or parent of Equinix or a corporation, partnership or other legal entity wholly owned by Equinix (collectively, an “Affiliated Party”), or (ii) a successor to Tenant by acquisition or merger, or by a consolidation or reorganization, or by any Transfer (as defined in the Loan Agreement) or series of Transfers resulting in any Person acquiring, directly or indirectly, more than a forty-nine percent (49%) ownership interest in Tenant (if such Person did not, prior to such Transfers, own at least forty-nine percent (49%) of the ownership interests of Tenant, pursuant to which Tenant ceases to exist as a legal entity (each such party a “Successor Party”); provided, however, that as a condition precedent to such Preapproved Assignment, such Preapproved Assignee shall either (x) satisfy the Investment Grade Criteria or the Financial Strength Criteria on the date of such Preapproved Assignment or (y) provide or cause to be provided to Landlord a guaranty in form and substance reasonably acceptable to Landlord and approved by Lender in writing from an entity that satisfies the Investment Grade Criteria or the Financial Strength Criteria on the date of such Preapproved Assignment.

(b) If Tenant desires to assign this Lease, whether by operation of law or otherwise, to a Person (“Non-Preapproved Assignee”) who would not be a Preapproved Assignee (“Non-Preapproved Assignment”) then Tenant shall, not less than twenty (20) days prior to the date on which it desires to make a Non-Preapproved Assignment submit to Landlord and Lender information regarding the following with respect to the Non-Preapproved Assignee (collectively the “Review Criteria”): (A) credit, (B) capital structure, (C) management, (D) operating history, (E) proposed use of the Leased Premises, (F) compliance with all OFAC and Patriot Act requirements, and (G) the name and financial information of the proposed replacement guarantor, if any. Landlord and Lender shall review such information and shall approve or disapprove the Non-Preapproved Assignee and replacement guarantor, if any (which approval shall not be unreasonably withheld) no later than the thirtieth (30^th) day following receipt of all such information, and Landlord and Lender shall be deemed to have acted reasonably in granting or withholding consent if such grant or disapproval is based solely on their review of the Review Criteria applying prudent business judgment. Tenant acknowledges that the ability of Landlord to give its consent will be subject to Landlord receiving the consent of Lender and any such assignment shall be null and void without Lender’s consent.

(d) Tenant shall have the right, without the consent of Landlord to enter into subleases, licenses or similar agreements (collectively a “Customer Agreement”) with its Customers, consistent with the custom and practice of the telecommunications industry, to “co-locate” such Customers’ telecommunications equipment within the Leased Premises or to otherwise occupy a portion of the Leased Premises and to allow such Customer to avail themselves of the services provided by Tenant from the Leased Premises consistent with the permitted uses of the Leased Premises.

(e) Except to the extent otherwise prohibited by law, any Customer Agreement shall at all times be subject and subordinate in all respects to all of the terms of this Lease and the lien of the SFT I Mortgage or any other Mortgage, and (A) no Customer Agreement shall in any way discharge or diminish any of the obligations of Tenant to Landlord under this Lease and Tenant shall remain directly and primarily liable under this Lease; (B) each Customer Agreement shall prohibit the Customer from engaging in any activities on the Leased Premises that are not consistent with those permitted under this Lease; and (C) each Customer Agreement shall have a term which expires on or prior to the Expiration Date, but shall be subject to earlier termination if this Lease is terminated before the Expiration Date.

(f) At the request of Tenant, Landlord, in its sole discretion, may enter into a non-disturbance and attornment agreement, in form and substance reasonably acceptable to Landlord, with respect to any Customer Agreement for the occupancy, use or lease of more than ten percent (10%) of the Leased Premises.

(g) If Tenant assigns all its rights and interest under this Lease as permitted under Section 19(a), the assignee under such assignment shall expressly assume all the obligations of Tenant hereunder, actual or contingent, including obligations of Tenant which may have arisen on or prior to the date of such assignment, by a written instrument delivered to Landlord at the time of such assignment. Except for any Preapproved Assignment (in which case such Tenant shall be released from its obligations under this Lease and only the successor Tenant shall continue to be liable), no assignment or sublease made as permitted by this Section 21 shall affect or reduce any of the obligations of Tenant hereunder, and all such obligations shall continue in full force and effect as obligations of a principal and not as obligations of a guarantor, as if no assignment or sublease had been made. No assignment or sublease shall impose any additional obligations on Landlord under this Lease.

(h) With respect to any Preapproved Assignment, Tenant shall provide to Landlord and Lender information reasonably required by Landlord or Lender to establish that any proposed Preapproved Assignment satisfies the criteria set forth above.

(i) Tenant shall, within ten (10) business days after the execution and delivery of any Preapproved Assignment, deliver a duplicate original copy thereof to Landlord and if requested by Lender, to Lender.

(j) Subject to the prior approval of Lender, Landlord may sell or transfer the Leased Premises at any time without Tenant’s consent to any third party subject to the rights of Tenant under this Lease and an assumption of the obligations of Landlord hereunder

by the purchaser or other transferee (each a “Third Party Purchaser”). In the event of any such transfer, Tenant shall attorn to any Third Party Purchaser as Landlord so long as such Third Party Purchaser and Landlord notify Tenant in writing of such transfer. At the request of Landlord, Tenant will execute such documents confirming the agreement referred to above and such other agreements as Landlord may reasonably request in form and substance reasonably acceptable to Tenant, provided that such agreements do not increase the liabilities and obligations of Tenant hereunder.

(a) The occurrence of any one or more of the following (after expiration of any applicable cure period as provided in Section 20(b)) shall, at the sole option of Landlord, constitute an “Event of Default” under this Lease:

(i) a failure by Tenant to make any payment of any Monetary Obligation as and when due;

(ii) a failure by Tenant duly to perform and observe, or a violation or breach of, any other provision hereof not otherwise specifically mentioned in this Section 20(a);

(iii) Tenant shall (A) voluntarily be adjudicated a bankrupt or insolvent, (B) seek or consent to the appointment of a receiver or trustee for itself, (C) file a petition seeking relief under the bankruptcy or other similar laws of the United States, any state or any jurisdiction, (D) make a general assignment for the benefit of creditors, or (E) be unable to pay its debts as they mature;

(iv) a court shall enter an order, judgment or decree appointing, without the consent of Tenant, a receiver or trustee for it or approving a petition filed against Tenant which seeks relief under the bankruptcy or other similar laws of the United States, any state or any jurisdiction, and such order, judgment or decree shall remain undischarged or unstayed sixty (60) days after it is entered;

(v) the Leased Premises shall have been vacated, provided it shall not be an Event of Default if the Leased Premises is vacant so long as Tenant is diligently pursuing a subtenant or assignee for the Leased Premises;

(vi) Tenant shall be liquidated or dissolved or shall begin proceedings towards its liquidation or dissolution; or

(vii) the estate or interest of Tenant in the Leased Premises shall be levied upon or attached in any proceeding and such estate or interest is about to be sold or transferred or such process shall not be vacated or discharged within ninety (90) days after it is made.

(b) No notice or cure period shall be required in any one or more of the following events: (A) the occurrence of an Event of Default under clause (i) (except as otherwise set forth below), (iii) (iv), (vi), or (vii) of Section 20(a); or (B) the default consists of a failure to provide any insurance required by Section 15 or an assignment or sublease entered into in violation of Section 19. If the default consists of the failure to pay Basic Rent, the applicable cure period shall be five (5) days from the date on which notice is given, but Landlord shall not be obligated to give notice of, or allow any cure period for, any such default more than one (1) time within any Lease Year. Any other Monetary Obligation, the applicable cure period shall be five (5) days from the date on which notice is given, but Landlord shall not be obligated to give notice of, or allow a cure period for, the same default more than one (1) time within any Lease Year. If the default consists of a default under clause (ii) of Section 20(a) (and is reasonably capable of cure), the applicable cure period shall be thirty (30) days from the date on which notice is given or, if the default cannot be cured within such thirty (30) day period and delay in the exercise of a remedy would not (in Landlord’s reasonable judgment) cause any material adverse harm to Landlord or the Leased Premises, the cure period shall be extended for the period required to cure the default, provided that Tenant shall commence to cure the default within the said thirty-day period and shall actively, diligently and in good faith proceed with and continue the curing of the default until it shall be fully cured.

(a) If an Event of Default shall have occurred and is continuing, Landlord shall have the right, at its sole option, then or at any time thereafter, to exercise its remedies and to collect damages from Tenant in accordance with this Section 21, subject in all events to applicable Law, without demand upon or notice to Tenant except as otherwise provided in Section 20(b) and this Section 21.

(i) Landlord may give Tenant notice of Landlord’s intention to terminate this Lease on a date specified in such notice. Upon such date, this Lease, the estate hereby granted and all rights of Tenant hereunder shall expire and terminate. Upon such termination, Tenant shall immediately surrender and deliver possession of the Leased Premises to Landlord in accordance with Section 24. If Tenant does not so surrender and deliver possession of all of the Leased Premises, Landlord may re-enter and repossess the Leased Premises not surrendered pursuant to applicable legal process, by summary proceedings, ejectment or any other lawful means or procedure. Upon or at any time after taking possession of the Leased Premises, Landlord may, by legal process, remove any Persons or property therefrom. Landlord shall be under no liability for or by reason of any such entry, repossession or removal. Notwithstanding such entry or repossession, Landlord may exercise the remedies set forth in and collect the damages described in this Section 21.

(ii) After repossession of the Leased Premises pursuant to clause (i) above, Landlord shall have the right to relet the Leased Premises to such tenant or tenants, for such term or terms, for such rent, on such conditions and for such uses as Landlord may reasonably determine, and collect and receive any rents payable by reason of such reletting. Landlord may make such Alterations in connection with such reletting as it may deem advisable in its sole reasonable discretion. Notwithstanding any such reletting, Landlord may collect the

damages described in this Section 21. Tenant shall reimburse Landlord for the costs and expenses of reletting any portion of the Leased Premises, including, but not limited to, all brokerage, advertising, legal, alteration, redecorating, repairing and other expenses reasonably incurred to secure a new tenant for the Leased Premises or portion thereof. In addition, if the consideration collected by Landlord upon any such reletting, after payment of the expenses of reletting the Leased Premises which have not been reimbursed by Tenant, is insufficient to pay monthly the full amount of the Rent, Tenant shall pay to Landlord the amount of each monthly deficiency as it becomes due. If such consideration is greater than the amount necessary to pay the full amount of the Rent, the full amount of such excess shall be retained by Landlord and shall in no event be payable to Tenant.

(b) If Landlord elects to terminate Tenant’s right to possession or, subject to applicable law, terminate this Lease upon the occurrence of an Event of Default, Landlord may (i) collect and recover from Tenant and Tenant shall pay Landlord, on demand, as and for liquidated and final damages, an accelerated lump sum amount equal to the amount by which Landlord’s estimate of the aggregate amount of Rent owing, from the date of such termination through the Expiration Date plus the aggregate of Landlord’s actual and estimated expenses of reletting the Leased Premises, exceeds the fair market rental value of the Leased Premises for the same period (after deducting from such fair market rental value the time needed to relet the Leased Premises and the amount of concessions which would normally be given to a new tenant) both discounted to present value at the rate equal to the then applicable discount rate of the Federal Reserve Bank of New York plus one percent (1%) and (ii) notwithstanding anything to the contrary contained herein, in its sole discretion, require removal of (A) any Additional Storage Tanks installed in the Leased Premises pursuant to Section 9(e) in accordance with all then applicable Legal Requirements, approvals, regulations and ordinances applicable thereto and Tenant shall cause such area of the Leased Premises to be fully restored with appropriate closure letters from the applicable governmental authorities (the “Storage Tank Removal”); and (B) except as expressly set forth in Section 12(f), all, or a portion of (as specified in such request), Alterations made during the Term of this Lease and require Tenant to restore the Leased Premises to their condition as of the Rent Commencement Date (its being understood that as of the Rent Commencement Date the Leased Premises will be a fully functioning IBX collocation facility).

(c) Notwithstanding anything to the contrary herein contained, in lieu of or in addition to any of the foregoing remedies and damages, Landlord may exercise any remedies and collect any damages available to it at law or in equity. If Landlord is unable to obtain full satisfaction pursuant to the exercise of any remedy, it may pursue any other remedy which it has hereunder at law or in equity.

(d) Landlord shall not be required to mitigate any of its damages hereunder unless required to by applicable Law. If any Law shall validly limit the amount of any damages provided for herein to an amount which is less than the amount agreed to herein, Landlord shall be entitled to the maximum amount available under such Law.

(e) No termination of this Lease, repossession or reletting of the Leased Premises, exercise of any remedy or collection of any damages pursuant to this Section 21 shall relieve Tenant of any Surviving Obligations.

(f) Upon the occurrence of any Event of Default, Landlord shall have the right (but no obligation) to perform any act required of Tenant hereunder at Tenant’s sole cost and expense and, if performance of such act requires that Landlord enter the Leased Premises, Landlord may enter the Leased Premises for such purpose during normal business hours upon reasonable prior written notice to Tenant (except in the event of an emergency). Furthermore, upon the occurrence of any Event of Default, Landlord shall have the right (but not the obligation) at Tenant’s sole cost and expense and without abatement of rent, to make any payment owed by Tenant to any party other than Landlord for which Tenant is liable under this Lease. Landlord’s election to make any such payment or perform any such act on Tenant’s part shall not give rise to any responsibility of Landlord to continue making the same or similar payments or performing the same or similar acts. Tenant agrees to reimburse Landlord upon demand for all sums so paid by Landlord and all necessary incidental costs, together with interest thereon at the Default Rate, from the date of such payment by Landlord until reimbursed by Tenant.

(g) No failure of Landlord (i) to insist at any time upon the strict performance of any provision of this Lease or (ii) to exercise any option, right, power or remedy contained in this Lease shall be construed as a waiver, modification or relinquishment thereof. A receipt by Landlord of any sum in satisfaction of any Monetary Obligation with knowledge of the breach of any provision hereof shall not be deemed a waiver of such breach, and no waiver by Landlord of any provision hereof shall be deemed to have been made unless expressed in a writing signed by Landlord.

(h) Landlord may also seek specific performance by Tenant in the case of breach by Tenant of one or more of its covenants contained in this Lease.

(i) All remedies are cumulative and concurrent and no remedy is exclusive of any other remedy. Each remedy may be exercised at any time an Event of Default has occurred and is continuing and may be exercised from time to time. No remedy shall be exhausted by any exercise thereof.

22. Notices. All notices, demands, requests, consents, approvals, offers, statements and other instruments or communications required or permitted to be given pursuant to the provisions of this Lease shall be in writing and shall be deemed to have been given and received for all purposes when delivered in person or by Federal Express or other reliable 24-hour delivery service or five (5) business days after being deposited in the United States mail, by registered or certified mail, return receipt requested, postage prepaid, addressed to the other party at its address stated above or when delivery is refused.

23. Estoppel Certificate. At any time upon not less than ten (10) business days’ prior written request by either Landlord or Tenant (the “Requesting Party”) to the other party (the “Responding Party”), the Responding Party shall deliver to the Requesting Party a statement in writing, executed by an authorized officer of the Responding Party, certifying (a) that, except as otherwise specified, this Lease is unmodified and in full force and effect, (b) the dates to which Basic Rent, Additional Rent and all other Monetary Obligations have been paid, (c) that, to the knowledge of the signer of such certificate and except as otherwise specified, no default by either Landlord or Tenant exists hereunder, and (d) such other matters as the Requesting Party may reasonably request. Any such statements by the Responding Party may be relied upon by the Requesting Party, any Person whom the Requesting Party notifies the Responding Party in its request for the Certificate is an intended recipient or beneficiary of the Certificate or their assignees and by any prospective purchaser or mortgagee of the Leased Premises.

24. Surrender. Upon the expiration or earlier termination of this Lease, Tenant shall peaceably leave and surrender the Leased Premises to Landlord in Good Condition and Repair. Upon such surrender, Tenant shall (a) remove from the Leased Premises all property which is owned by Tenant or third parties other than Landlord and any Alterations or Additional Storage Tanks if required by Landlord pursuant to Section 21, and (b) repair any damage caused by such removal. Property not so removed shall become the property of Landlord, and Landlord may thereafter cause such property to be removed from the Leased Premises. The reasonable cost of removing and disposing of such property and repairing any damage to the Leased Premises caused by such removal shall be paid by Tenant to Landlord within thirty (30) days of written demand. Landlord shall not in any manner or to any extent be obligated to reimburse Tenant for any such property which becomes the property of Landlord pursuant to this Section 24 and Section 12 hereof.

25. No Merger of Title. There shall be no merger of the leasehold estate created by this Lease with the fee estate in the Leased Premises by reason of the fact that the same Person may acquire or hold or own, directly or indirectly, (a) the leasehold estate created hereby or any part thereof or interest therein and (b) the fee estate in the Leased Premises or any part thereof or interest therein, unless and until all Persons having any interest in the interests described in (a) and (b) above which are sought to be merged shall join in a written instrument effecting such merger and shall duly record the same.

(a) Tenant shall keep adequate records and books of account with respect to the Leased Premises, in accordance with generally accepted accounting principles (“GAAP”) consistently applied, and shall permit Landlord and Lender, subject to the provisions of Section 4(c) above, by their respective agents, accountants and attorneys, upon reasonable notice to Tenant, to visit and inspect the Leased Premises, or such other location where such books and records are maintained, during normal business hours and examine (and make copies of) the records and books of account. Upon the request of Landlord (either telephonically or in writing), Tenant shall provide the requesting party with copies of any information to which such party would be entitled in the course of a personal visit.

(b) To the extent not available on the EDGAR website of the Securities and Exchange Commission (“EDGAR”) or other public information sources, Tenant shall deliver to Landlord and Lender within one hundred twenty (120) days of the close of each fiscal year, annual audited financial statements of Equinix, Inc. prepared by nationally recognized independent certified public accountants. To the extent not available on EDGAR or other public information sources, Tenant shall also furnish to Landlord within forty-five (45) days after the end of each of the three remaining quarters all filings, if any, of Form 10-K, Form 10-Q and other required filings with the Securities and Exchange Commission pursuant to the provisions of the Securities Exchange Act of 1934, as amended, or any other Law.

Anything contained herein to the contrary notwithstanding, any claim based on or in respect of any liability of Landlord under this Lease shall be enforced only against the Leased Premises and not against any other assets, properties or funds of (a) Landlord, (b) any director, member, officer, general partner, limited partner, employee or agent of Landlord, or any general partner of Landlord, any of its general partners or shareholders (or any legal representative, heir, estate, successor or assign of any thereof), (c) any predecessor or successor partnership or corporation (or other entity) of Landlord, or any of its general partners, either directly or through Landlord or its general partners or any predecessor or successor partnership or corporation or their shareholders, officers, directors, employees or agents (or other entity), or (d) any other Person.

(a) In connection with the Mortgage Lender Financing, Tenant agrees to supply Lender with such notices and information as Tenant is required to give to Landlord hereunder in accordance with Section 22 herein and to extend the rights of Landlord hereunder to any Lender. Tenant shall provide any other consent or statement and shall execute any and all other documents that Lender reasonably requires in connection with such Mortgage Lender Financing and any subsequent Mortgage, so long as the same do not adversely affect any right, benefit or privilege of Tenant or increase Tenant’s obligations under this Lease in any material respect. Furthermore, in connection with the Mortgage Lender Financing and any subsequent Mortgage, Tenant acknowledges that Landlord will assign its interest in this Lease and the Guaranty to Mortgage Lender and any successor Lender as additional security for the Mortgage Lender Financing and any subsequent financing. Notwithstanding anything to the contrary herein, this Section 28(a) shall be operative only during such time as a Mortgage encumbers the Leased Premises.

(b) In the event of any act or omission of Landlord which would give Tenant the right, immediately or after lapse of a period of time, to cancel or terminate this Lease, or to claim a partial or total eviction, Tenant shall not exercise such right (i) until it has given written notice of such act or omission to Lender at the addresses set forth in Section 22 above, and (ii) unless such act or omission shall be one which is not capable of being remedied by Landlord or Lender within the time period provided herein, until the period for remedying such act or omission provided herein shall have elapsed following the giving of such notice and following the time when Lender shall have become entitled under any applicable encumbrance to remedy the same (which reasonable period shall in no event be less than the period to which Landlord would be entitled under this Lease or otherwise, after similar notice, to effect such remedy), provided Lender shall with due diligence give Tenant written notice of its intention to remedy such act or omission, and Lender shall commence and thereafter continue with reasonable diligence to pursue its remedies under any applicable encumbrance and to remedy such act or omission. Notwithstanding the foregoing, Lender shall have no obligation to act, perform or effect any such remedy.

(c) If Tenant desires to obtain or refinance any loan that encumbers Tenant’s interest in the Leased Premises, Tenant’s equipment and any Alterations approved by Landlord and which Landlord and Lender have expressly agreed in writing may be removed by Tenant at the end of the term of this Lease, any such loan or encumbrance shall not require the consent of Landlord or Lender and shall not be deemed subject to the provisions of Section 19 of this Lease. In the event that Landlord receives written notice identifying any such lender as the holder or beneficiary of any such loan or encumbrance, Landlord shall thereafter endeavor to provide such lender with duplicate copies of any notice of an Event of Default given by Landlord to Tenant hereunder; provided, however, failure to provide such lender with such duplicate notice shall not constitute a failure to give notice to Tenant or prevent or impair Landlord’s ability to exercise its remedies under this Lease. Furthermore, Landlord shall accept from such lender any curative acts on account of such Event of Default. Notwithstanding anything to the contrary in the foregoing, Landlord shall not be required to recognize such lender under the Lease unless such lender is the direct tenant under this Lease and has a credit rating by a major national credit agency of BBB or better (or equivalent) or, in the event such lender assumes this Lease through an affiliated designee, such lender provides to Landlord a replacement guaranty in form reasonably acceptable to Landlord from a party with a net worth and financial strength at least equivalent to the Tenant as of the date hereof. No further assignments of this Lease will be permitted after such lender or its designee assumes this Lease without Landlord’s and Lender’s prior written consent.

29. Subordination and Attornment. This Lease and Tenant’s interest hereunder shall be subordinate to any Mortgage or other security instrument hereafter placed upon the Leased Premises by Landlord, including without limitation, the first priority lien of Lender, and to any and all advances made or to be made thereunder, to the interest thereon, and all renewals, amendments, modifications, replacements and extensions thereof. Tenant further agrees that upon the request of Lender, Tenant will execute a subordination and attornment agreement providing as follows:

(b) Neither the Lender nor its successors and assigns shall (A) be liable for any misrepresentation, act or omission of Landlord, and (B) be bound by any amendment or modification of this Lease, not expressly provided for in this Lease, or by any prepayment of more than one month’s fixed rent, unless such amendment or modification or prepayment shall have been expressly approved in writing by such Lender.

(c) If a Lender, any successor or assignee of Lender, or any other purchaser at any foreclosure sale under such Lender’s Mortgage or in connection with the delivery of a deed in lieu of foreclosure (collectively “Successor Landlord”) shall succeed to the rights of Landlord under this Lease, whether through possession or foreclosure action or delivery of a new lease or deed, then at Successor Landlord’s request and election (it being understood and agreed that in the alternative Successor Landlord may elect to terminate this Lease), Tenant shall attorn to and recognize Successor Landlord as Tenant’s landlord under this Lease, and shall promptly execute and deliver any instrument that Successor Landlord may reasonably request to evidence such attornment. Upon such attornment this Lease shall continue in full force and

effect as, or as if it were, a direct lease between Successor Landlord and Tenant upon all of the terms, conditions and covenants as are set forth in this Lease and shall be applicable after such attornment except that Successor Landlord shall not be: (i) liable for any misrepresentation, act or omission of Landlord (except that Successor Landlord shall be responsible for correcting any continuing defaults and obligations which exist at the time Successor Landlord succeeds to Landlord’s interest under the Lease), or (ii) bound by any amendment or modification of this Lease, not expressly consented to by Lender, or by any prepayment of more than one month’s fixed rent, unless such amendment or modification or prepayment shall have been expressly approved in writing by such Lender.

(d) In the event this Lease is terminated by a Successor Landlord in connection with a foreclosure or deed in lieu of foreclosure, Tenant shall cooperate in the assignment, to the extent same are assignable, of its licenses, permits, and entitlements and any other contracts specific to the operation of the Leased Premises to the extent requested by Successor Landlord.

30. Tax Treatment; Reporting. Landlord and Tenant each acknowledge that each shall treat this transaction as a true lease for state law purposes and shall report this transaction as a Lease for Federal income tax purposes. For Federal income tax purposes each shall report this Lease as a true lease with Landlord as the owner of the Leased Premises and Equipment and Tenant as the tenant of such Leased Premises and Equipment including: (1) treating Landlord as the owner of the property eligible to claim depreciation deductions under Section 167 or 168 of the Internal Revenue Code of 1986 (the “Code”) with respect to the Leased Premises and Equipment, (2) Tenant reporting its Rent payments as rent expense under Section 162 of the Code, and (3) Landlord reporting the Rent payments as rental income.

31. Guaranty. Concurrently with the execution of this Lease, Tenant shall deliver Landlord a Guaranty of Lease (the “Guaranty”) duly executed by Guarantor guaranteeing Tenant’s obligations under the Lease in the form attached as Exhibit “E” hereto.

(a) The Landlord and Tenant represent and warrant to each other that no broker or finder was instrumental in arranging or bringing about this transaction. If any other person brings a claim for a commission or finder’s fee based upon any contact, dealings or communication with Landlord or Tenant, then the party through whom such person makes his claim shall defend the other party from such claim, and shall indemnify such party and hold such party harmless from any and all costs, damages, claims, liabilities or expenses (including without limitation, court costs and reasonable attorneys’ fees and disbursements) incurred by such party in defending against the claim.

(b) The paragraph headings in this Lease are used only for convenience in finding the subject matters and are not part of this Lease or to be used in determining the intent of the parties or otherwise interpreting this Lease.

(c) As used in this Lease, the singular shall include the plural and any gender shall include all genders as the context requires and the following words and phrases shall have the following meanings: (i) “including” shall mean “including without limitation”; (ii) “provisions” shall mean “provisions, terms, agreements, covenants and/or conditions”; (iii) “lien” shall mean “lien, charge, encumbrance, title retention agreement, pledge, security interest, mortgage and/or deed of trust”; (iv) “obligation” shall mean “obligation, duty, agreement, liability, covenant and/or condition”; (v) “the Leased Premises” shall mean “the Leased Premises or any part thereof or interest therein”; (vi) “any of the Land” shall mean “the Land or any part thereof or interest therein”; (vii) “any of the Improvements” shall mean “the Improvements or any part thereof or interest therein”; and (viii) “any of the Equipment” shall mean “the Equipment or any part thereof or interest therein”.

(d) Any act which Landlord is permitted to perform under this Lease may be performed at any time and from time to time by Landlord or any person or entity designated by Landlord. Each appointment of Landlord as attorney-in-fact for Tenant hereunder is irrevocable and coupled with an interest. Landlord shall not unreasonably withhold or delay or condition its consent whenever such consent is required under this Lease. Time is of the essence with respect to the performance by Tenant of its obligations under this Lease.

(e) Landlord shall in no event be construed for any purpose to be a partner, joint venturer or associate of Tenant or of any subtenant, operator, concessionaire or licensee of Tenant with respect to the Leased Premises or otherwise in the conduct of their respective businesses.

(f) This Lease and any documents which may be executed by Tenant on or about the effective date hereof at Landlord’s request constitute the entire agreement between the parties and supersede all prior understandings and agreements, whether written or oral, between the parties hereto relating to the Leased Premises and the transactions provided for herein. Landlord and Tenant are business entities having substantial experience with the subject matter of this Lease and have each fully participated in the negotiation and drafting of this Lease. Accordingly, this Lease shall be construed without regard to the rule that ambiguities in a document are to be construed against the drafter.

EQUINIX OPERATING CO., INC., a Delaware corporation

Title:		CFO

THIS GUARANTY OF LEASE (“Guaranty”) is made as of February 2, 2007, by EQUINIX, INC., a Delaware corporation (“Guarantor”), having a business address at 301 Velocity Way, 5^th Floor, Foster City, California 94404, to CHI 3, LLC., a Delaware limited liability company (“Landlord”), having a business address at c/o Equinix, Inc., 301 Velocity Way, 5^th Floor, Foster City, California 94404, with reference to the following facts:

A. Landlord and Equinix Operating Co., Inc., a Delaware corporation (“Tenant”), have entered into and executed that certain Master Lease (the “Lease”) of even date herewith with respect to the premises located at 1905 – 1945 Lunt Avenue, Elk Grove Village, Illinois 60007.

B. Guarantor indirectly owns one hundred percent (100%) of the ownership interest in Landlord and will benefit from, among other things, the revenue generated from Tenant’s operations on the Leased Premises (as defined in the Lease).

D. Landlord is not willing to execute the Lease based solely upon the credit of Tenant. Guarantor is willing to execute this Guaranty of Lease in support of Tenant’s commitments made under the Lease for the express and intended purpose of inducing Landlord to enter into the Lease.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Guarantor hereby covenants, agrees and guarantees to Landlord and its successors and assigns as follows:

1. Guaranty. Guarantor does hereby absolutely and unconditionally guarantee to Landlord the prompt payment of all amounts that Tenant, or any assignee of the Lease, may at any time owe under the Lease, any extensions, renewals or modifications thereof, and further guarantees to Landlord the full, prompt and faithful performance by Tenant, or any assignee of the Lease, of each and all of the covenants, terms, and conditions of the Lease, or any extensions, modifications or renewals thereof and any holdover term following the term granted thereby, to be hereafter performed and kept by Tenant, or any assignee of the Lease (all such obligations of Tenant under the Lease are referred to as “Tenant’s Obligations”). This is a Guaranty of payment and performance and not merely of collection. This Guaranty shall include any liability of Tenant which shall accrue under the Lease for any period proceeding as well as any period following the term specified in the Lease, including, without limitation, any rent or other amounts payable pursuant to the terms of the Lease as a result of Tenant’s holding over. If Tenant or any assignee of the Lease fails to make any payment when due under the Lease or to perform any duties, obligations or covenants contained in the Lease to be performed by Tenant, or any assignee of the Lease, Guarantor will immediately and unconditionally pay to Landlord such amounts and perform such duties, obligations and covenants after expiration of any applicable grace or cure periods in the Lease; provided, however that such grace and cure periods shall be contemporaneous with and not in addition to any grace or cure period available to Tenant under the terms of the Lease. Guarantor shall pay to Landlord on demand, all expenses (including, without limitation, attorneys’ fees and costs) arising out of or relating to the enforcement or protection of Landlord’s rights hereunder.

2. Independent Obligations. Guarantor’s obligations hereunder are absolute, primary, unconditional and irrevocable obligations which are independent of the obligations of Tenant, or any assignee of the Lease, and a separate action or actions may be brought and prosecuted against Guarantor whether or not action is brought against Tenant or any such assignee or whether or not Tenant or any such assignee be joined in any such action or actions.

3. Rights of Landlord. Guarantor authorizes Landlord, without notice or demand and without affecting its liability hereunder, from time to time to (a) extend, accelerate, or otherwise change the time for any payment provided for in the Lease, or any covenant, term or condition of the Lease, in any respect to impair or suspend the Landlord’s remedies or rights against Tenant in connection with the Lease, and to consent to any assignment, subletting or reassignment of the Lease; (b) take and hold security for any payment provided for in the Lease or for the performance of any covenant, term or condition of the Lease, or exchange, waive or release any such security; (c) apply such security and direct the order or manner of sale thereof as Landlord in its discretion may determine. Landlord may without notice or the consent of Guarantor assign this Guaranty, the Lease, or the rents and other sums payable thereunder. Notwithstanding any termination, renewal, extension or holding over of the Lease, this Guaranty shall continue until all of Tenant’s Obligations have been fully and completely performed by Tenant or any assignee of the Lease.

Guarantor shall not be released by any act or event which might, but for this provision of this Guaranty, be deemed a legal or equitable discharge of a surety, or by reason of any waiver, extension, modification, forbearance or delay or other act or omission of Landlord or its failure to proceed promptly or otherwise as against Tenant or Guarantor, or by reason of any action taken or omitted or circumstance which may or might vary the risk or affect the rights or remedies of Guarantor as against Tenant, or by reason of any further dealings between Tenant and Landlord, whether relating to the Lease or otherwise, and Guarantor hereby expressly waives and surrenders any defense to its liability hereunder based upon any of the foregoing acts, omissions, things, agreements, waivers or any of them; it being the purpose and intent of this Guaranty that the obligations of Guarantor hereunder are absolute and unconditional under any and all circumstances.

Guarantor further agrees that to the extent Tenant or Guarantor makes any payment to Landlord in connection with Tenant’s Obligations and all or any part of such payment is subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid by Landlord or paid over to a trustee, receiver or any other entity, whether under any bankruptcy act or otherwise (any such payment is hereinafter referred to as a “Preferential Payment”), then this Guaranty shall continue to be effective or shall be reinstated, as the case may be, and, to the extent of such payment or repayment by Landlord, Tenant’s Obligations or part thereof intended to be satisfied by such Preferential Payment shall be revived and continued in full force and effect as if said Preferential Payment had not been made.

4. Waiver of Defenses. Guarantor hereby expressly waives and relinquishes all rights, remedies and defenses accorded by applicable law to guarantors and sureties and agrees not to take advantage of any such rights, remedies or defenses. Without limiting in any way the foregoing, Guarantor hereby expressly waives (a) any right to require Landlord to (i) proceed against Tenant or any other person or entity; (ii) proceed against or exhaust any security held

from Tenant or Guarantor; (iii) pursue any other remedy in Landlord’s power which Guarantor cannot itself pursue, and which would lighten its burden; or (iv) cause a marshalling of the assets of Tenant or Guarantor; (b) all statutes of limitations as a defense to any action brought against Guarantor by Landlord to the fullest extent permitted by law; (c) any defense based upon any legal disability of Tenant, or any assignee of the Lease, or any discharge or limitation of the liability of Tenant, or any assignee of the Lease, to Landlord, whether consensual or arising by operation of law or any bankruptcy, reorganization, receivership, insolvency, or debtor-relief proceeding, or from any other cause; (d) presentment, demand, protest and notice of any kind; (e) any defense based upon or arising out of any defense which Tenant, or any assignee of the Lease, may have to the payment or performance of any part of Tenant’s Obligations; and (f) any and all of its rights of subrogation, reimbursement, indemnification, and contribution and any other rights and defenses that are or may become available to Guarantor. Guarantor waives all demands upon and notices to Tenant, or any assignee of the Lease, and to Guarantor, including demands for performance, notices of non-performance, notices of nonpayment and notice of acceptance of this Guaranty.

5. Assumption of Obligations and Waivers as to Financial Condition. Guarantor’s obligations hereunder shall not be affected by any failure on the part of Landlord to inform Guarantor concerning Tenant’s financial condition or notify Guarantor of any adverse change in Tenant’s financial condition of which Landlord becomes aware. Guarantor assumes the obligation to make such inquiries with respect to such financial condition as Guarantor deems necessary or prudent in the circumstances.

6. Costs and Expenses. If Guarantor fails to perform any of its obligations under this Guaranty or if any dispute arises between the parties hereto concerning the meaning or interpretation of any provision of this Guaranty, then the defaulting party or the party not prevailing in such dispute, as the case may be, shall pay any and all costs and expenses incurred by the other party on account of such default and/or in enforcing or establishing its rights hereunder, including, without limitation, court costs and reasonable attorneys’ fees and disbursements. Any such attorneys’ fees and other expenses incurred by either party in enforcing a judgment in its favor under this Guaranty shall be recoverable separately from and in addition to any other amount included in such judgment, and such attorneys’ fees obligation is intended to be severable from the other provisions of this Guaranty and to survive and not be merged into any such judgment.

7. Notices. Notices or other communications given under this Guaranty shall be effective only if rendered or given in writing, sent by certified mail with a return receipt requested or by facsimile with a confirmation receipt (and a copy sent by a nationally recognized overnight courier service) or delivered personally or by a nationally recognized overnight courier service: (a) to Guarantor at Guarantor’s address set forth above; or (b) to Landlord at Landlord’s address set forth above. Any such notice or other communication shall be deemed to have been rendered or given two (2) days after the date when it shall have been mailed if sent by certified mail, or upon actual receipt if sent by facsimile, or upon the date personal delivery is made, or upon actual delivery if sent by overnight courier.

8. Delay; Cumulative Remedies. No delay or failure by Landlord to exercise any right or remedy against Tenant or Guarantor will be construed an a waiver of that right or remedy. No waiver or modification of any provision of this Guaranty nor any termination of this Guaranty shall be effective unless stated in writing and signed by the party charged with such waiver or modification, and then only to the extent so stated, and no such waiver shall apply to any circumstance other than the specific instance for which it is given. In no event shall a waiver of any provision of this Guaranty be implied from any course of conduct on the part of Guarantor and/or Landlord and/or any third party. All remedies of Landlord against Tenant and Guarantor are cumulative.

9. Representations and Warranties of Guarantor. Guarantor hereby represents, warrants and covenants that Guarantor has a financial interest in Tenant and will derive a material and substantial benefit, directly or indirectly, from the Lease and from the making of this Guaranty by Guarantor.

(a) This Guaranty shall bind Guarantor, its successors and assigns, and shall inure to the benefit of Landlord and its successors and assigns. Guarantor consents to the assignment of this Guaranty by Landlord to Mortgage Lender (as such term is defined in the Lease) or any successor thereof as additional security for the Mortgage Lender Financing (as such term is defined in the Lease).

(b) The invalidity or unenforceability of any one or more provisions of this Guaranty will not affect any other provision.

(d) This Guaranty and each and every term and provision thereof shall be construed in accordance with the laws of the State of Illinois. Guarantor consents to the exercise of personal jurisdiction by the courts of the State of Illinois over Guarantor, and agrees that any action to enforce the provisions of this Guaranty may be brought in any state or federal court located within the County of Cook, State of Illinois.

IN WITNESS WHEREOF, Guarantor has executed this instrument under seal on the day and year first above written.
