5. Term:		Approximately seventy-two (72) full calendar months (i.e., commencing on the Commencement Date and expiring on the last day of the seventy-second (72nd) full calendar month thereafter).
		For the avoidance of doubt, Landlord and Tenant acknowledge and agree that, if the Commencement Date occurs on a date that is other than the first (1st) day of a calendar month, the Term of this Lease shall be deemed to have been automatically extended by the number of calendar days in the Partial Month, such that the Term of the Lease shall then be equal to the number of full calendar months described above, plus the number of calendar days in the Partial Month.
		For example:
		a. If the Commencement Date occurs on January 1, 2011, then the seventy-two (72) full calendar month Term of this Lease would commence January 1, 2011, and expire on December 31, 2016.

However, in this example, the first (1st) month of the seventy-two (72) full calendar month Term of this Lease would, for the purposes of calculating the expiration of the Term of the Lease, be deemed to be the month of February, 2011.
6. Extension Options/		Two (2) Extension Options, each to extend the Term for an Extension Term of sixty
Extension Term:		(60)months, subject to the terms of Section 2.3, below.

2. TERM.

     2.1 Term. The term of this Lease, and Tenant’s obligation to pay Rent under this Lease, shall commence on the Commencement Date and shall continue in effect for the Term of the Lease, as the same may be extended, or earlier terminated, in accordance with the express terms of this Lease.

     2.2 Delivery of Tenant Space. Landlord and Tenant acknowledge and agree that, by virtue of the occurrence of the Commencement Date, Landlord shall be deemed to have delivered the Tenant Space to Tenant, and Tenant shall be deemed to have accepted the same.

Additionally, provided that Landlord is working diligently using commercially reasonable efforts after the Commencement Date to complete the Card Reader Installation, Landlord shall not be in default of its obligation to complete the Card Reader Installation. Landlord agrees to deliver the Card Reader Completion Notice to Tenant upon Landlord’s completion of the Card Reader Installation.

If Tenant duly exercises an Extension Option, Landlord and Tenant shall execute an amendment reflecting such exercise. Notwithstanding anything to the contrary herein, any attempted exercise by Tenant of an Extension Option shall, at the election of Landlord, be invalid, ineffective, and of no force or effect if, on the date on which Tenant delivers an Extension Option Exercise Notice, or on the date on which the Extension Term is scheduled to commence, there shall be an uncured Event of Default by Tenant under this Lease.

All Base Rent shall be paid to Landlord in monthly installments in advance on the first day of each and every calendar month throughout the Term of this Lease; provided, however, that (a) the installment of Base Rent for the first (1^st) full calendar month of the Term shall be payable upon Tenant’s execution of this Lease; and (b) if the Term of this Lease does not commence on the first day of a calendar month, the Base Rent for the Partial Month shall (i) be calculated on a per diem basis determined by dividing the Base Rent above by the total number of calendar days in such Partial Month and multiplying such amount by the number of days remaining in such Partial Month from and after (and including) the Commencement Date, and (ii) be paid by Tenant to Landlord on the Commencement Date. Except as set forth in this Section 3.1, Tenant shall not pay any installment of Rent more than one (1) month in advance.

     3.2 Installation Fee. Tenant shall pay the Installation Fee to Landlord, no later than the thirtieth (30^th) day following receipt of an invoice therefor. Landlord and Tenant acknowledge that the Installation Fee represents remuneration to Landlord in consideration of the costs incurred by Landlord in connection with the New Pathway-B Installation and the New Pathway-C Installation and otherwise in connection with Landlord’s fixturization of the Tenant Space related to this Lease.

     3.3 Payments Generally. Base Rent payable hereunder by Tenant (i) shall be payable to Landlord when due, without any prior notice or demand therefor, in lawful money of the United States without any abatement, offset or deduction whatsoever (except as specifically provided otherwise herein), and (ii) shall be payable to Landlord at the address of Landlord specified in Item 12 of the Basic Lease Information (or to such other person or to such other place as Landlord may from time to time designate in writing to Tenant). All forms of Additional Rent payable hereunder by Tenant (aa) shall be payable to Landlord within thirty (30) days after Tenant’s receipt of an invoice for same, without any other notice or demand therefor, in lawful money of the United States without any abatement, offset or deduction whatsoever (except as specifically provided otherwise herein), and (bb) shall be payable to Landlord at the address of Landlord specified in Item 12 of the Basic Lease Information (or to such other person or to such other place as Landlord may from time to time designate in writing to Tenant). No receipt of money by Landlord from Tenant after the termination of this Lease, the service of any notice, the commencement of any suit, or a final judgment for possession shall reinstate, continue or extend the Term of this Lease or affect any such notice, demand, suit or judgment. No partial payment by Tenant shall be deemed to be other than on account of the full amount otherwise due, nor shall any endorsement or statement on any check or any letter accompanying any check or payment be deemed an accord and satisfaction, and Landlord shall be entitled to accept such payment without compromise or prejudice to any of the rights of Landlord hereunder or under any Applicable Laws. In the event that the Commencement Date or the expiration of the Term (or the date of any earlier termination of this Lease) falls on a date other than the first or last day of a calendar month, respectively, the Rent payable for such partial calendar month shall be prorated based on a per diem basis.

          3.3.1 Landlord acknowledges and agrees that the Base Rent payable to Landlord under this Lease is on a “gross” basis except as otherwise expressly set forth herein, in consideration for all costs as may be incurred by Landlord for the operation, maintenance, management, insurance and repair of the Premises, Building and Property and the real estate taxes thereon. Except as otherwise expressly provided in this Lease, Tenant shall not be responsible for payment of any of Landlord’s costs or expenses in connection with the Tenant Space, Building and Property.

     3.4 Late Payments. As it relates to any Late Payment, Tenant shall, in addition to Tenant’s obligation to pay the Late Payment to Landlord, also be required to pay to Landlord, as Additional Rent, (i) a Late Charge, and (ii) Late Payment Interest from the Delinquency Date until the date the foregoing are paid, collectively, to cover Landlord’s additional administrative costs and damages related to such Late Payment, which are difficult, if not impossible, to determine. In no event, however, shall the charges permitted under this Section 3.4, or elsewhere in this Lease, to the extent the same are considered to be interest under Applicable Law, exceed the maximum lawful rate of interest. Landlord’s acceptance of any Late Charge, or any Late Payment Interest, shall not be deemed to constitute a waiver of Tenant’s default with respect to the Late Payment, nor prevent Landlord from exercising any of the other rights and remedies available to Landlord hereunder or under any Applicable Laws.

     3.5 Utilities. Tenant shall be billed directly by Landlord as Additional Rent for the costs of Aggregate Direct Electric Loads in a manner consistent in all material respects with the then manner of billing for electrical service provided by the local electric utility company and in accordance with the then applicable pricing structures and rate schedules as filed by such utility with the applicable governmental authority from time to time.

          3.5.1 Notwithstanding the foregoing, if the Metering Equipment — Tenant Space in installed in such a manner so as to not capture Systems Efficiency Losses, Landlord shall have a right to add an amount reasonably determined by landlord to Tenant’s Aggregate Direct Electric Loads sufficient to compensate Landlord for actual System Efficiency Losses attributable to Tenant’s Aggregate Direct Electric Loads.

          3.5.2 Tenant shall pay a proportionate share of all Ancillary Utility Costs, which proportionate share shall be a fraction expressed as a percentage, the numerator of which shall be Tenant’s Aggregate Direct Electric Loads and the denominator of which shall be the sum of the Aggregate Direct Electric Loads for all of the tenants then operating in the Building.

          3.5.3 Notwithstanding the foregoing, if Landlord reasonably determines that the method of calculating Aggregate Direct Electric Loads, System Efficiency Losses and/or Ancillary Utility Costs is inadequate to capture the costs related to same that should otherwise be attributable to the Tenant Space, Landlord and Tenant shall mutually agree on a different formula/calculation, as necessary, to appropriately capture such costs. Additionally, in the event that Landlord determines that it is no longer commercially impractical to separately meter some or all of Unmetered Direct Electric Loads, System Efficiency Losses and/or Ancillary Utility Costs, then Landlord may cause the equipment related to the foregoing to be separately metered to the Tenant Space at Landlord’s sole cost and expense. In either event, Landlord and Tenant shall execute an amendment to this Lease reflecting such modification. For the avoidance of doubt, it is the intent of the parties that this Section 3.5 represents a mechanism only for Landlord’s cost recovery with regard to utilities (including electrical power) serving, provided to and/or used in or for the Tenant Space, and that there is no intent for Tenant’s Utility Payment to include any element of profit to Landlord in connection therewith.

          3.5.4 Generator Fuel Usage. Additionally, and except to the extent that Generator Fuel Usage represents Maintenance Fuel Usage, Tenant shall pay its proportionate share of the cost of all Generator Fuel, which proportionate share shall be a fraction expressed as a percentage, the numerator of which shall be Tenant’s Aggregate Direct Electric Loads and the denominator of which shall be the sum of the Aggregate Direct Electric Loads for all of the tenant then operating in the Building. Landlord shall bill Tenant not more frequently than monthly for the amount of the Generator Fuel Payment. Tenant shall pay the Generator Fuel Payment to Landlord, as Additional Rent, within thirty (30) days of delivery of each Generator Fuel Payment invoice. For the avoidance of doubt, it is the intent of the parties that this Section 3.5.4 represents a mechanism only for Landlord’s cost recovery with regard to non-maintenance related Generator Fuel Usage, and that there is no intent for Tenant’s Generator Fuel Payment to include any element of profit to Landlord in connection therewith.

          3.5.5 Tenant’s Additional Rent Audit Right. Landlord shall keep complete books and records regarding all Additional Rent charges made by Landlord hereunder. All such records pertaining to a particular calendar year shall be retained for at least one (1) full calendar year after the expiration of such particular calendar year (i.e., all such records pertaining to the calendar year 2012 shall be retained at least until the end of the calendar 2013). Tenant shall have the right, once per twelve (12) month period during the Term, to audit the applicable Additional Rent records of Landlord to confirm that the Additional Rent charges billed to Tenant conform to the provisions of this Lease. Such right, as it relates to any calendar year, shall be exercisable by Tenant within one (1) year after the expiration of such calendar year. Landlord shall cooperate with Tenant during each such audit in providing Tenant reasonable access to Landlord’s books and records for the calculation of such items of Additional Rent during normal business hours to enable Tenant to audit such books and records. If the audit discloses any overpayment on the part of Tenant, then Tenant shall be entitled to a credit on the next succeeding installment of Additional Rent, following Landlord’s confirmation of the correctness of such audit conclusions, for an amount equal to the overcharge, and such credit shall be extended to succeeding installments of Additional Rent in the event such overcharge exceeds the amount of the next succeeding such installment. In the event the Term of this Lease has expired or been earlier terminated, then Tenant shall be entitled to a refund of such excess from Landlord within thirty (30) days after Landlord’s confirmation of the correctness of such audit conclusions. In

addition, in the event such audit by Tenant discloses such an overcharge in excess of ten percent (10%) of the amount payable pursuant to this Lease, then Landlord shall pay to Tenant the reasonable costs and expenses of such audit, not to exceed Five Thousand and No/100 Dollars ($5,000.00) for any particular audit.

4. TAXES.

     4.1 Taxes — Equipment. Tenant shall be liable for and shall pay before delinquency all Taxes — Equipment. If any such Taxes — Equipment are levied or assessed against Landlord or the Property, and if Landlord elects to pay the same, Tenant shall pay to Landlord as Additional Rent, within thirty (30) days of Landlord’s demand therefor, that part of such Taxes — Equipment for which Tenant is liable hereunder. In the event that Tenant desires to contest such Taxes — Equipment, Landlord agrees to reasonably cooperate with Tenant in connection therewith at Tenant’s cost.

     4.2 Taxes — Other. Tenant shall pay to Landlord, as Additional Rent and within thirty (30) days of Landlord’s demand therefor, and in such manner and at such times as Landlord shall direct from time to time by written notice to Tenant all Taxes — Other.

          4.2.1 Landlord represents and warrants that, to the best of Landlord’s Actual Knowledge, (a) no Taxes-Other are due or payable with regard to this Lease as of the Effective Date of this Lease; and (b) no Taxes-Other will be due or payable with regard to this Lease with regard to the calendar year in which the Effective Date occurs.

Tenant agrees to reimburse Landlord for any losses, costs or damages caused by unauthorized parties who gain access to the Tenant Space or the Building through access cards, keys or other access devices provided to Tenant (or any other Tenant Party) by Landlord. Tenant agrees to reimburse Landlord, as Additional Rent, for any additional insurance premium charged by Landlord’s insurance carrier for any insurance policy by reason of Tenant’s failure to comply with the provisions of this Section 6.1.1.

          6.2 Datacenter Rules and Regulations. Tenant’s Permitted Use shall be subject to, and Tenant, and all other Tenant Parties, shall comply fully with the Datacenter Rules and Regulations. Landlord shall have the right, from time-to-time, to change, amend and/or supplement the Datacenter Rules and Regulations as may be deemed by Landlord, in the exercise of its sole but good faith discretion, advisable for the safety, care and/or cleanliness of the Tenant Space, the Building and/or the Property, and/or for the preservation of good order in any of same; provided, however, that such changes to the Datacenter Rules and Regulations may not increase Tenant’s monetary obligations under this Lease or unreasonably interfere with Tenant’s Permitted Use of the Tenant Space.

In the event of a conflict between the Datacenter Rules and Regulations and the terms of this Lease, the terms of this Lease shall govern. Tenant shall be responsible for causing the other Tenant Parties to comply with the Datacenter Rules and Regulations.

Tenant, at Tenant’s sole cost and expense, shall timely take all action required to cause all Alterations and Tenant’s (and all other Tenant Parties’) use of the Tenant Space to comply at all times during the Term of this Lease in all respects with all Applicable Laws; provided, however, that in no event shall Tenant be obligated to make improvements of a capital nature to the Premises, Building or Property except to correct work performed by Tenant or its contractors.

               6.3.1.1 Landlord represents and warrants to Tenant that, as of the Effective Date (a) to the best of Landlord’s Actual Knowledge, the Building and the Premises are in material compliance with all Applicable Laws, including the requirements of all easement and encumbrance documents; (b) the Permitted Use of the Premises are permitted at the Property; (c) Landlord holds fee simple title to the Property, subject to all matters of record, and (as of the Effective Date) subject to no mortgage; (d) Landlord has full power and authority to enter into this Lease and has obtained all consents and taken all actions necessary to enable Landlord to do so; and (e) to the best of Landlord’s Actual Knowledge, no other party has any possessory right to the Premises or has claimed the same.

          6.3.2 Hazardous Materials. Tenant agrees that neither Tenant, nor any other Tenant Party, shall Handle any Hazardous Materials in the Tenant Space or any portion of the Building or the Property. Additionally, Tenant agrees that neither Tenant, nor any other Tenant Party, shall use the Tenant Space in any manner which may directly or indirectly lead to any non-compliance with any Environmental Law.

Tenant’s actual electricity consumption for the Premises, as reasonably determined by Landlord pursuant to such measurement method or methods as Landlord shall employ from time to time (including, without limitation, the use of sub-meters and/or pulse meters, electrical surveys and/or engineer’s estimates), shall not at any time, exceed the Electricity Consumption Threshold for the respective Suite. The power drawn by all of Tenant’s Personal Property located in a Suite shall be included in the calculation of Tenant’s actual electricity consumption for such Suite. In the event that an ECT Overage occurs, Tenant agrees to take immediate action to cause power consumption in each Suite to be at or below the Electricity Consumption Threshold for the respective Suite.

Landlord reserves the right, but without assuming any duty, to institute additional access control measures in order to further control and regulate access to the Building or any part thereof. Landlord shall not, under any circumstances, be responsible for providing or supplying security services to the Tenant Space or any part of the Building in excess of the Landlord’s Access Control Systems (and, unless expressly agreed in writing by Landlord, Landlord shall not under any circumstances be deemed to have agreed to provide any access control services in excess of the above specified Landlord’s Access Control Systems).

     8.2 Tenant’s Maintenance. During the Term of this Lease, Tenant shall, at Tenant’s sole cost and expense, maintain the Tenant Space and Tenant’s equipment therein in good order and in a clean and safe condition.

The foregoing notwithstanding, Landlord’s consent shall not be required for any usual and customary installations, repairs, maintenance, and removals of electrical distribution equipment downstream of the PDUs in the

Premises, equipment and telecommunication cables within the Tenant Space if and to the extent that such installations, repairs, maintenance, and removals (i) are usual and customary within the industry, (ii) are in compliance with the Datacenter Rules and Regulations, and (iii) will not adversely affect the Building’s structure, the provision of services to other Building tenants, or the Building’s electrical, plumbing, HVAC, life safety or mechanical systems.

Additionally, all such contractors, laborers, material men and others must obtain (and provide Landlord evidence of) such insurance as Landlord may reasonably require, prior to any such entry; provided that, in no event shall such insurance requirements exceed those that are described on Exhibit “B-1”, attached hereto.

Tenant agrees that, upon the expiration or earlier termination of this Lease, Tenant shall at Tenant’s sole cost and expense, promptly remove all of Tenant’s Personal Property, and shall restore those portions of the Building and/or the Tenant Space damaged by such removal of (or by the initial installation of) such Tenant’s Personal Property to their condition existing immediately prior to the installation or placement of such items (including, without limitation, the replacement of all damaged floor tiles in the Premises), ordinary wear and tear and damage by fire or other casualty excepted. If Tenant fails to promptly remove any such Tenant’s Personal Property pursuant to this Section 8.4, Landlord shall have the right to cause the removal of such Tenant’s Personal Property and the restoration of those portions of the Building and/or the Tenant Space damaged by such removal to their condition existing immediately prior to the installation or placement of such Tenant’s Personal Property, ordinary wear and tear excepted, in which case Tenant agrees to reimburse Landlord within thirty (30) days of Landlord’s demand therefor, for all of Landlord’s actual and reasonable out of pocket costs of removal and restoration plus an administrative fee equal to five percent (5%) of such costs.

If the part of the Building or the Property that is taken or condemned as part of the Taking contains a part of the Tenant Space, the Building or the Property that, in Landlord’s reasonable discretion, is material to the operation of the Tenant Space, Landlord may terminate this Lease by notice to Tenant given within sixty (60) days following the date upon which Landlord received notice of such Taking. If Landlord so notifies Tenant, this Lease shall terminate upon the date set forth in the notice, which date shall not be more than thirty (30) days following the giving of such notice.

               9.1.2.4 Tenant’s Termination Right — Partial Taking. If the part of the Building or the Property that is taken or condemned as part of the Taking contains any portion of the Premises that existed immediately prior to such Taking, or if, by reason of such Taking, Tenant no longer has reasonable means of access to the Tenant Space or Tenant’s Permitted Use of the Premises is materially impaired, Tenant may terminate this Lease by notice to Landlord given within sixty (60) days following the date upon which Tenant received notice of such Taking. If Tenant so notifies Landlord, this Lease shall terminate upon the date set forth in the notice, which date shall not be more than thirty (30) days following the giving of such notice.

               9.1.2.5 Restoration — Taking. If this Lease shall not have been terminated pursuant to Sections 9.1.2.3 or 9.1.2.4, above, Landlord, at Landlord’s expense, shall, as soon as is reasonably practicable, restore that part of the Tenant Space that was not taken or condemned as part of the Taking to a self-contained rental unit substantially equivalent (with respect to character, quality, appearance and services) to that which existed immediately prior to occurrence of the Taking, excluding Tenant’s Personal Property; provided, however, that in the event Tenant receives an award for Tenant’s Alterations, such amounts shall be applied towards the restoration of such items.

               9.1.2.6 Base Rent Abatement — Taking. In the event that this Lease is terminated pursuant to Sections 9.1.2.1, 9.1.2.3 or 9.1.2.4, above, Landlord shall refund to Tenant any prepaid Base Rent, less any sum then owing to Landlord by Tenant. If, however, this Lease is not terminated pursuant to any of said Sections, Base Rent shall be reduced proportionately to the extent that the Premises is reduced as a result of the Taking.

               9.1.2.7 Taking Award Rights. Landlord reserves the right to receive the entirety of the condemning authority’s award related to a Taking of any portion of the Property. The foregoing notwithstanding, in the event that this Lease is terminated in connection with any Taking, Landlord expressly permits Tenant to make a separate claim against the condemning authority, in any appropriate proceeding, for the value of Tenant’s

unamortized, but taken, leasehold improvements or other improvements to the Tenant Space made by Tenant and for Tenant’s moving expenses related to such Taking, but only if such claim and/or recovery does not reduce the condemnation/taking award otherwise payable to Landlord in connection with such Taking. If any such award that is made, or compensation that is paid, to either party specifically includes an award or amount for the other, the party first receiving the same shall promptly make an accounting of same to the other.

     9.2 Tenant’s Remedy. Tenant’s termination rights and rights to Base Rent abatement, to the extent provided above in this Article 9, shall be Tenant’s sole and exclusive remedies in the event of a Casualty Event or Taking.

     9.3 Tenant’s Insurance. Tenant shall, at Tenant’s expense, procure and maintain throughout the Term of this Lease a policy or policies of insurance in accordance with the terms and requirements set forth in Exhibit “B-1” to this Lease. All of Tenant’s insurance policies with respect to the Tenant Space shall be endorsed so as to include a waiver of subrogation in accordance with and to the full extent of Tenant’s waiver of claims with respect to the Landlord Group set forth in Section 14.1.1 of this Lease.

          9.3.1 The commercial general liability policies procured by Tenant hereunder shall name Landlord and Landlord’s managing agent, and any Holders designated by Landlord as additional insureds. Prior to occupying the Tenant Space, and prior to the expiration of each such policy, Tenant shall submit to Landlord certificates of insurance evidencing such policies (and the applicable renewals thereof) being in effect. All insurance policies procured hereunder shall contain a provision stating that the insurer shall endeavor to provide at least thirty (30) days’ written notice to Landlord and all others named as additional insureds prior to any cancellation or material modification of such policy.

     9.4 Landlord’s Insurance. Landlord shall, at Landlord’s expense, procure and maintain throughout the Term of this Lease a policy or policies of insurance in accordance with the terms and requirements set forth in Exhibit “B-2” to this Lease. Each of such insurance policies shall be endorsed so as to include a waiver of subrogation in accordance with and to the full extent of Landlord’s waiver of claims with respect to the Tenant Group set forth in Section 14.1.2 of this Lease. For the avoidance of doubt, however, Landlord and Tenant acknowledge and agree that, in no event, shall Landlord be obligated to carry any insurance covering any of Tenant’s Personal Property, any Alteration to the Tenant Space made by or on behalf of Tenant, or covering any Tenant Party.

10. TRANSFERS.

     10.1 Restrictions on Transfers; Landlord’s Consent. Except as otherwise expressly set forth in Section 10.1.1 and Section 10.5, below, to the contrary, Tenant shall not effect a Transfer, without Landlord’s express prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed. Except as otherwise expressly set forth in this Lease, no Transfer (whether voluntary, involuntary or by operation of law) shall be valid or effective without Landlord’s prior written consent and, at Landlord’s election, any such Transfer or attempted Transfer shall constitute an Event of Default by Tenant under Section 15.1.2 of this Lease.

          10.1.1 Permitted Transfer. Notwithstanding anything to the contrary in this Lease, Tenant may, without the consent of Landlord (and without being subject to Landlord’s recapture rights under Section 10.3, below) undertake Permitted Transfers.

     10.2 Notice to Landlord. If Tenant desires to make any Transfer (other than a Permitted Transfer, for which Tenant must merely notify Landlord prior to the occurrence of same), then at least ten (10) business days (but no more than one hundred eighty (180) days) prior to the proposed effective date of the Transfer, Tenant shall submit a Transfer Notice to Landlord. If, thereafter, Tenant modifies any of the terms and conditions relevant to a proposed Transfer specified in the Transfer Notice, Tenant agrees to re-submit such Transfer Notice to Landlord for its consent pursuant to all of the terms and conditions of this Article 10.

     10.3 Landlord’s Recapture Rights. Except with regard to a Permitted Transfer, at any time within ten (10) business days after Landlord’s receipt of all (but not less than all) of the information and documents described in Section 10.2, Landlord shall have the right (but not the obligation), exercisable by written notice to Tenant, to elect to cancel and terminate this Lease.

     10.4 No Release; Subsequent Transfers. No Transfer (whether or not a Permitted Transfer) will release the undersigned Tenant from Tenant’s obligations under this Lease or alter the primary liability of the undersigned Tenant to pay the Rent and to perform all other obligations to be performed by Tenant hereunder. In no event shall the acceptance of any payment by Landlord from any other person be deemed to be a waiver by Landlord of any provision hereof. Consent by Landlord to one Transfer will not be deemed consent to any subsequent Transfer. In the event of breach by any Transferee in the performance of any of the terms hereof, Landlord may proceed directly against the undersigned Tenant without the necessity of exhausting remedies against such Transferee.

     10.5 Colocation. Landlord acknowledges that the business to be conducted by the undersigned Tenant in the Premises may require Tenant to enter into Colocation Agreements that will permit Colocation Parties to engage in Colocation Activities. Landlord expressly agrees that Tenant may, without the need for Landlord’s consent, enter into such Colocation Agreements; provided, however, that (a) the Colocation Agreements, and each Colocation Party’s use of the Tenant Space, must comply with the terms of this Lease (including the Datacenter Rules and Regulations) and all Applicable Laws; (b) the Colocation Agreements, and the Colocation Parties’ rights thereunder, shall be subject and subordinate at all times to this Lease and all of its provisions, covenants and conditions; and (c) in no event may the rights of any Colocation Party, vis a vis the members of the Landlord Group, be greater than the rights of Tenant hereunder. Anything to the contrary contained herein notwithstanding, Landlord and Tenant acknowledge and agree that the Colocation Agreements shall not constitute, or be deemed to be, the grant of a leasehold interest, or otherwise constitute, or be deemed to be, a real property interest.

     10.6 Excess Rent. Landlord and Tenant agree that, if Tenant assigns this Lease, or subleases any part of the Tenant Space, for any Excess Rent, then Tenant shall pay to Landlord, as Additional Rent, fifty percent (50%) of any such Excess Rent immediately upon Tenant’s receipt thereof.

11. ESTOPPEL CERTIFICATES. At any time and from time to time, within fifteen (15) days after written request by Landlord, Tenant shall execute, acknowledge and deliver to Landlord a statement in writing certifying all matters relating to this Lease reasonably requested by Landlord and/or any prospective purchaser of the Building and/or the Property and/or any Holder. Tenant acknowledges and agrees that any statement delivered (or to be delivered) pursuant to this Article 11 may be relied upon by Landlord and any prospective purchaser of the Building and/or the Property and by any current and/or prospective Holder, and any assignee of any such Holder.

12. SUBORDINATION AND ATTORNMENT; HOLDER RIGHTS.

     12.1 Subordination and Attornment. Without the necessity of any additional document being executed by Tenant for the purpose of effecting a subordination, and at the election of Landlord or any Holder, this Lease will be subject and subordinate at all times to all Security Documents, which may now exist or hereafter be executed which constitute a lien upon or affect the Property or any portion thereof, or Landlord’s interest and estate in any of said items. Notwithstanding the foregoing, Landlord reserves the right to subordinate (or cause the subordination of) any such Security Documents to this Lease. In the event of any termination or transfer of Landlord’s estate or interest in the Property, the Building or the Tenant Space by reason of any termination or foreclosure of any such Security Documents (and notwithstanding any subordination of such Security Document to this Lease that may or may not have occurred), at the election of Landlord’s successor in interest, Tenant agrees to attorn to and become the tenant of such successor, in which event Tenant’s right to possession of the Property will not be disturbed as long as Tenant is not in default under this Lease beyond applicable notice or cure periods. Tenant hereby waives any right under any Applicable Law or otherwise to terminate or otherwise adversely affect this Lease and the obligations of Tenant hereunder in the event of any termination or transfer of Landlord’s estate or interest in the Property, the Building or the Tenant Space by reason of any termination or foreclosure of any such Security Documents. Tenant covenants and agrees to execute and deliver, within fifteen (15) days of receipt thereof, and in the form reasonably required by Landlord or any Holder, any additional documents evidencing the priority or subordination of this Lease and Tenant’s agreement to attorn with respect to any such Security Document; provided, however, any such agreement subordinating this Lease to such lease, mortgage or deed of trust shall contain a non-disturbance provision that is reasonably acceptable to such Holder, Landlord and Tenant in accordance with Section 12.3, below.

     12.2 Holder Protection. Tenant agrees to give each Noticed Holder, by registered or certified mail, a copy of any notice of default served upon the Landlord by Tenant. Tenant further agrees that if Landlord shall have failed to cure such default within thirty (30) days after such notice to Landlord (or if such default cannot be cured or corrected within that time, then within such additional time as may be necessary if Landlord has commenced such cure within such thirty (30) days and is diligently pursuing the remedies or steps necessary to cure or correct such default), then, prior to Tenant pursuing any remedy for such default provided hereunder, at law or in equity, any Noticed Holder shall have an additional thirty (30) days within which to cure or correct such default (or if such default cannot reasonably be cured or corrected within that time, then such additional time as may be necessary if the Noticed Holder has commenced within such thirty (30) days and is diligently pursuing the remedies or steps necessary to cure or correct such default).

     12.3 SNDA. Simultaneously with execution of this Lease if the Building is subject to any Security Document, or if the Building is not so subject as of the Effective Date, then at any time that the Building is hereafter made subject to any Security Document(s), Landlord shall use commercially reasonable good faith efforts to cause the Holder to deliver an SNDA to Tenant. Notwithstanding anything herein to the contrary, the subordination of this Lease to any Security Document hereafter placed upon the Building, and Tenant’s agreement to attorn to the Holder as provided in this Article 12, shall be conditioned upon the Holder entering into an SNDA.

13. SURRENDER OF TENANT SPACE; HOLDING OVER.

     13.1 Tenant’s Method of Surrender. Upon the expiration of the Term of this Lease, or upon any earlier termination of this Lease or the termination of Tenant’s right to possess the Tenant Space, Tenant shall, subject to the provisions of this Article 13 and Section 8.4, quit and surrender possession of the Tenant Space to Landlord in good working order and clean condition, ordinary wear and tear excepted.

          13.1.1 Surrender of Suite 1.5 Tenant Space. Notwithstanding the foregoing, no later than the Suite 1.5 Expiration Date, Tenant shall, subject to the provisions of this Article 13 and Section 8.4, quit and surrender possession of the Suite 1.5 Tenant Space to Landlord in good working order and clean condition, ordinary wear and tear excepted.

     13.2 Disposal of Tenant’s Personal Property. If any property not belonging to Landlord remains in the Tenant Space after the expiration of, or within fifteen (15) days after any earlier termination of, the Term of this Lease or the termination of Tenant’s right to possess the Tenant Space, Tenant shall be deemed to have abandoned such property and to have authorized Landlord to make such disposition of such property as Landlord may desire without liability for compensation or damages to Tenant or any other Tenant Party.

     13.3 Holding Over. If Tenant should remain in possession of all or any portion of the Tenant Space after the expiration of the Term of this Lease (or any earlier termination of this Lease or the termination of Tenant’s right to possess the Tenant Space), without the execution by Landlord and Tenant of a new lease or an extension of the Term of this Lease, then Tenant shall be deemed to be occupying the entire Tenant Space as a tenant-at-sufferance, upon all of the terms contained herein, except as to term and Base Rent and any other provision reasonably determined by Landlord to be inapplicable. During any such holdover period, Tenant shall pay to Landlord a monthly Base Rent in an amount equal to one hundred fifty percent (150%) of the Base Rent payable by Tenant to Landlord during the last month of the Term of this Lease and one hundred percent (100%) of the Additional Rent payable by Tenant to Landlord during the last month of the Term of this Lease. The monthly rent payable for such holdover period shall in no event be construed as a penalty or as liquidated damages for such retention of possession, nor shall such monthly rent be considered to be any form of Consequential Damages related to such retention of possession. Neither any provision hereof nor any acceptance by Landlord of any rent after any such expiration or earlier termination shall be deemed a consent to any holdover hereunder or result in a renewal of this Lease or an extension of the Term, or any waiver of any of Landlord’s rights or remedies with respect to such holdover. As such, and notwithstanding any provision to the contrary contained herein, Landlord expressly reserves the right to require Tenant to surrender possession of the Tenant Space upon the expiration of the Term of this Lease or upon the earlier termination hereof or at any time during any holdover and the right to assert any remedy at law or in equity to evict Tenant and collect damages in connection with any such holdover.

          13.3.1 Notwithstanding the foregoing, should Tenant remain in possession of all or any portion of the Suite 1.5 Tenant Space after the expiration of the Suite 1.5 Term, without the execution by Landlord and Tenant of an amendment to this Lease to permit otherwise, then Tenant shall be deemed to be occupying the Suite 1.5 Tenant Space as a tenant-at-sufferance, upon all the terms contained herein, except as to term and Suite 1.5 Base Rent and any other provision reasonably determined by Landlord to be inapplicable. During any such holdover period, Tenant shall pay to Landlord a monthly Suite 1.5 Base Rent in an amount equal to one hundred fifty percent (150%) of the Suite 1.5 Base Rent payable by Tenant to Landlord during the last month of the Suite 1.5 Term and one hundred percent (100%) of the Additional Rent payable by Tenant to Landlord, with respect to Suite 1.5, during the last month of Suite 1.5 Term. The monthly rent payable for such holdover period shall in no event be construed as a penalty or as liquidated damages for such retention of possession, nor shall such monthly rent be considered to be any form of Consequential Damages related to such retention of possession. Neither any provision hereof nor any acceptance by Landlord of any rent after any such expiration or earlier termination shall be deemed a consent to any holdover hereunder or result in a renewal of this Lease or an extension of the Suite 1.5 Term, or any waiver of any of Landlord’s rights or remedies with respect to such holdover. As such, and notwithstanding any provision to the contrary contained herein, Landlord expressly reserves the right to require Tenant to surrender possession of the Suite 1.5 Tenant Space upon the expiration of the Suite 1.5 Term or upon the earlier termination thereof or at any time during any holdover and the right to assert any remedy at law or in equity to evict Tenant from Suite 1.5 and collect damages in connection with any such holdover.

     13.4 Survival. The provisions of this Article 13 shall survive the expiration or early termination of this Lease.

14. WAIVERS; INDEMNIFICATION; CONSEQUENTIAL DAMAGES; LIENS.

     14.1 Waivers.

          14.1.1 Tenant hereby waives its rights against the Landlord Group with respect to any claims or damages or losses for bodily injury to persons and/or damage to any Tenant’s Personal Property, which are caused by or result from (i) risks insured against under any insurance policies which are required to be obtained and maintained by Tenant under this Lease, and were, in fact, carried by Tenant at the time of such claim, damage, loss or injury, or (ii) risks which would have been covered under any insurance required to be obtained and maintained by Tenant under this Lease had such insurance been obtained and maintained as required, including all such claims, damages and losses, which are caused by or result from the negligence or willful misconduct of any member of the Landlord Group. The foregoing waivers shall be in addition to, and not a limitation of, any other waivers or releases contained in this Lease.

          14.1.2 Landlord hereby waives its rights against the Tenant Group with respect to any claims or damages or losses for bodily injury to persons and/or for damage to the Building, the Property and/or Landlord’s equipment and fixtures, which are caused by or result from (i) risks insured against under any insurance policies which are required to be obtained and maintained by Landlord under this Lease and that were, in fact, carried by Landlord at the time of such claim, damage, loss or injury, or (ii) risks which would have been covered under any insurance required to be obtained and maintained by Landlord under this Lease had such insurance been obtained and maintained as required, including all such claims, damages and losses, which are caused by or result from the negligence or willful misconduct of any member of the Tenant Group.

          14.2.1 Indemnification by Tenant. To the maximum extent permitted by law, Tenant hereby agrees to indemnify, defend, and hold harmless Landlord and the other members of the Landlord Group from and against (and to reimburse Landlord and the other members of the Landlord Group for) any and all Claims arising from and/or in connection with:

               (i) the use or occupancy of the Tenant Space or any portion of the Building or the Property by Tenant or any other Tenant Party and/or any person claiming by, through or under Tenant or any other Tenant Party, including, without limitation:

                    (f) Claims by any Tenant Party (or any individual accessing the Tenant Space on any Tenant Party’s behalf) for bodily injury;

                    (g) Tenant’s failure to surrender the Tenant Space upon the expiration or any earlier termination of this Lease or the termination of Tenant’s right to possess the Tenant Space in accordance with the terms of this Lease; and

                    (h) the removal, exercise of dominion over and/or disposition of any of Tenant’s Personal Property that is left in the Tenant Space after the expiration of the Term of this Lease in violation of Section 13.2.

               (ii) the active gross negligence or willful misconduct of Tenant or any other Tenant Party with respect to the Tenant Space, the Building or the Property;

               (iii) any person or entity, other than the Tenant’s Broker listed in Item 13 of the Basic Lease Information, making a claim for any commission or other compensation in connection with the execution of this Lease or the leasing of the Tenant Space to Tenant if based on an allegation that such claimant dealt through Tenant.

               14.2.1.1 The foregoing notwithstanding, Tenant shall not be required to indemnify Landlord or any other member of the Landlord Group to the extent that the relevant Claims were caused by the negligence or willful misconduct of any member of the Landlord Group.

               14.2.1.2 In the event that any action or proceeding is brought against Landlord or any other member of the Landlord Group by reason of any indemnified Claim, Tenant, upon notice from Landlord, shall defend such action or proceeding at Tenant’s cost and expense by counsel reasonably approved by Landlord. Tenant agrees that no settlement offer shall be offered or accepted by Tenant in connection with any such indemnification and/or defense without Landlord’s prior written consent, which shall not be unreasonably withheld, conditioned or delayed. This indemnity provision and Tenant’s obligations under this Section 14.2 shall survive the expiration or termination of this Lease as to any matters arising prior to such expiration or termination or prior to Tenant’s vacation of the Tenant Space and the Building. Notwithstanding any provision to the contrary contained in this Section 14.2, nothing contained in this Section 14.2 shall be interpreted or used in any way to affect, limit, reduce or abrogate any insurance coverage provided by any insurer to either Tenant or Landlord.

          14.2.2 Indemnification by Landlord. Landlord hereby agrees to defend, indemnify, and hold harmless Tenant and the other members of the Tenant Group from and against (and to reimburse Tenant and the other members of the Tenant Group for) all Claims to the extent arising from or in connection with the active gross negligence or willful misconduct of Landlord or any member of the Landlord Group at the Property.

               14.2.2.1 The foregoing notwithstanding, Landlord shall not be required to indemnify Tenant or any other member of the Tenant Group to the extent that the relevant Claims were caused by the negligence or willful misconduct of any member of the Tenant Group.

               14.2.2.2 In the event that any action or proceeding is brought against Tenant or any other member of the Tenant Group by reason of any indemnified Claim, Landlord upon notice from Tenant shall defend such action or proceeding at Landlord’s cost and expense by counsel reasonably approved by Tenant. Landlord agrees that no settlement offer shall be offered or accepted by Landlord in connection with any such

indemnification and/or defense without Tenant’s prior written consent, which shall not be unreasonably withheld, conditioned or delayed. This indemnity provision and Landlord’s obligations under this Section 14.2 shall survive the expiration or termination of this Lease as to any matters arising prior to such expiration or termination.

     14.3 Consequential Damages. Notwithstanding anything to the contrary (express or implied) contained herein, under no circumstances whatsoever shall Landlord or Tenant ever be liable under this Lease for first-party or third-party Consequential Damages; provided however, that to the maximum extent permitted by law, Tenant hereby agrees to indemnify and hold Landlord and the other members of the Landlord Group harmless with regard to (and to reimburse Landlord and any other members of the Landlord Group for) any and all claims by, through, or under any Tenant Space Customer for Consequential Damages related to any use of the Tenant Space or any equipment located within the Tenant Space, excluding all such claims, if any, which arise as a result of the negligence of any member of the Landlord Group.

     14.4 Liens. Notwithstanding anything to the contrary herein, in no event shall Tenant have any right (express or implied) to create or permit there to be established any lien or encumbrance of any nature against the Tenant Space, the Building or the Property or against Landlord’s or Tenant’s interest therein or hereunder, including, without limitation, for any improvement or improvements by Tenant, and Tenant shall fully pay the cost of any improvement or improvements made or contracted for by Tenant. Tenant shall require each contractor which it engages to perform any improvements or alterations within the Tenant Space or elsewhere in the Building or the Property, to acknowledge and agree in writing that it is performing its work under its agreement with Tenant solely for the benefit of Tenant and that Tenant is not acting as Landlord’s agent. Any mechanic’s lien filed against the Tenant Space, the Building or the Property, or any portion of any of the above, for work claimed to have been done, or materials claimed to have been furnished to Tenant, shall be duly discharged or bonded off by Tenant within thirty (30) days after notice to Tenant of the filing of the lien.

15. TENANT DEFAULT.

          The parties hereto acknowledge and agree that all of the notice periods provided in this Section 15.1 are in lieu of, and not in addition to, the notice requirements of any Applicable Laws.

     15.2 Remedies. Upon the occurrence of any Event of Default by Tenant, Landlord shall, in addition to an action for money damages, specific performance and/or injunctive relief, have the option to pursue any one or more of the remedies described in Section 1 of Exhibit “D” attached hereto and incorporated herein by this reference, each and all of which shall, subject to applicable law, be cumulative and nonexclusive.

16. LANDLORD’S LIABILITY.

     16.1 Landlord Default; Tenant’s Remedies.

          16.1.1 Landlord Default. The following shall constitute a Landlord Default:

               16.1.1.1 if: (a) Landlord shall fail to perform or observe any of Landlord’s Lease Undertakings, and (b) such failure continues for a period of ten (10) days following written notice to Landlord of such failure; provided, however, that in the event that Landlord’s failure to perform or observe any of Landlord’s Lease Undertakings cannot reasonably be cured within ten (10) days following written notice to Landlord, such failure to cure shall not be a Landlord Default if Landlord commences its cure within such ten (10) day period and thereafter diligently prosecutes the curing thereof to completion. Landlord agrees to use commercially reasonable efforts to provide daily updates to Tenant regarding progress toward such completion.

               16.1.1.2 The filing or execution or occurrence of any one of the following, provided the same is not dismissed or otherwise rectified within sixty (60) days: (i) a petition in bankruptcy or other insolvency proceeding by or against Landlord, (ii) a petition or answer seeking relief for Landlord under any provision of the Bankruptcy Act, (iii) an assignment by Landlord for the benefit of creditors, (iv) a petition or other proceeding by or against Landlord for the appointment of a trustee, receiver or liquidator of Landlord or any of Landlord’s property, (v) a proceeding by any governmental authority for the dissolution or liquidation of Landlord, or (vi) any other instance whereby Landlord or any general partner of Landlord or any guarantor of Landlord’s obligations under this Lease shall cease doing business as a going concern.

          16.1.2 Tenant’s Remedies. Except as otherwise expressly provided herein, (a) in the event of any Landlord Default, Tenant’s sole and exclusive remedies for any such failure shall be an action for money damages, specific performance and/or injunctive relief, and (b) in no event shall Tenant have the right to terminate the Lease nor shall Tenant’s obligation to pay Base Rent or other charges under this Lease abate based upon any default by Landlord of its obligations under the Lease. In that connection, Tenant hereby expressly waives any right conveyed to Tenant by virtue of any law granting Tenant a lien upon the property of Landlord and/or upon rental due to Landlord or granting Tenant a right to withhold Rent and/or terminate this Lease.

     16.2 Landlord’s Liability. In consideration of the benefits accruing under this Lease to Tenant, and notwithstanding anything to the contrary contained in the Lease Documents, it is expressly understood and agreed by and between the parties to this Lease that:

          (i) the collective recourse of Tenant and its successors and assigns against Landlord (and the liability of Landlord to Tenant, its successors and assigns) with respect to (a) any actual or alleged breach or breaches by or on the part of Landlord of any of Landlord’s Lease Undertakings, and (b) any other matter relating to Tenant’s occupancy of the Tenant Space, shall be limited, in the aggregate, solely to an amount equal to Landlord’s Liability Cap;

          (ii) other than Landlord’s Liability Cap, Tenant shall have no recourse against any other assets of Landlord;

          (iii) Tenant shall have no recourse against any assets of any member of the Landlord Group other than Landlord;

          (iv) except to the extent of Landlord’s Liability Cap, no personal liability or personal responsibility of any sort with respect to any of Landlord’s Lease Undertakings, or any alleged breach thereof, is assumed by, or shall at any time be asserted or enforceable against, Landlord; and

          (v) no personal liability or personal responsibility of any sort with respect to any of Landlord’s Lease Undertakings, or any alleged breach thereof, is assumed by, or shall at any time be asserted or enforceable against, any member of the Landlord Group other than Landlord.

     16.3 Transfer of Landlord’s Interest. Landlord (and each of Landlord’s successors-in-interest) shall have the right, from time to time, to assign its interest and obligations, in writing and/or by operation of law, in and under this Lease to any third party to whom Landlord conveys its interest in the Property. Once and if Landlord (and/or any successor to Landlord) shall convey its interest in the Property to a third party, (a) Landlord (and each such successor) shall be fully released from all of the obligations and liabilities of Landlord under the Lease Documents accruing on or after the date of such transfer of Landlord’s interest in the Property to such third party, and (b) Tenant agrees to look solely to the successor-in-interest of Landlord for all such obligations and liabilities accruing on or after the date of such transfer. If any security has been given by Tenant to secure the faithful performance of any of the covenants of this Lease, Landlord shall transfer or deliver said security, as such, to Landlord’s successor in interest and thereupon Landlord shall be discharged from any further liability with regard to said security.

          16.3.1 Status as a Real Estate Investment Trust. Landlord shall have the right, from time to time, to assign part of its interest and obligations in and under this Lease to a wholly owned subsidiary of Landlord (or a wholly owned subsidiary of Landlord’s parent company), if and to the extent that Landlord determines such partial transfer is necessary or advisable in connection with the status of Landlord, or any other member of the Landlord Group, as a real estate investment trust.

          16.3.2 Partial Assignment. Should Landlord assign part of its obligation to a third party, Landlord shall, subject to the terms of Sections 14.1, 14.2 and 16.2, retain the responsibility for ensuring that the assigned obligations are properly performed under this Lease, including ensuring that such third party provides all reasonable account management services.

17. MISCELLANEOUS.

     17.1 Severability. If it is found in a final judgment by a court of competent jurisdiction (not subject to further appeal) that any term or provision hereof is invalid or unenforceable, (i) the remaining terms and provisions hereof shall be unimpaired and shall remain in full force and effect; and (ii) the invalid or unenforceable term or provision shall be replaced by a term or provision that is valid and enforceable and that comes closest to effectuating the intention of such invalid or unenforceable term or provision.

     17.2 No Waiver. No failure or delay by Landlord to insist on the strict performance of any obligation, covenant, agreement, term or condition of this Lease, or to exercise any right or remedy available upon such non-performance, will constitute a waiver thereof, and no breach or failure by Tenant to perform will be waived, altered or modified, except by written instrument signed by Landlord.

     17.3 Attorneys’ Fees and Costs. If either Landlord or Tenant initiates any litigation, mediation, arbitration or other proceeding regarding the enforcement, construction or interpretation of this Lease, then the non-prevailing party shall pay the prevailing party’s reasonable attorneys’ fees and costs (including, without limitation, all reasonable expense reimbursements, reasonable expert witness fees, reasonable litigation costs, court or

     arbitration tribunal costs, filing fees, reasonable exhibit fees, reasonable forensic consultant fees, reasonable litigation support costs, the costs of appeals and reasonable attorneys’ fees and costs incurred in connection with post-judgment collection and enforcement efforts). In addition, if it should otherwise be necessary or proper for Landlord to consult an attorney concerning this Lease for the review of instruments evidencing a proposed Transfer or for the purpose of collecting Rent, Tenant agrees to pay to Landlord its actual attorneys’ fees whether suit be brought or not to the extent such fees exceed $1,000.00. The parties agree that this Section 17.3 shall survive the expiration or termination of this Lease.

     17.4 Waiver of Right to Jury Trial. TO THE FULLEST EXTENT PERMITTED BY LAW, LANDLORD AND TENANT EACH EXPRESSLY WAIVES ITS RIGHT TO TRIAL BY JURY IN ANY TRIAL HELD AS A RESULT OF A CLAIM ARISING OUT OF, IN CONNECTION WITH, OR IN ANY MANNER RELATED TO THIS LEASE IN WHICH LANDLORD AND TENANT ARE ADVERSE PARTIES. FOR THE AVOIDANCE OF DOUBT, THE FILING OF A CROSS-COMPLAINT BY ONE AGAINST THE OTHER IS SUFFICIENT TO MAKE THE PARTIES “ADVERSE.”

     17.5 Headings; Time; Survival. The headings of the Articles, Sections, Schedules and Exhibits of this Lease are for convenience only and do not define, limit or construe the contents thereof. Words of any gender used in this Lease shall be held and construed to include any other gender, and words in the singular number shall be held to include the plural, unless the context otherwise requires. In all instances where a party is required to pay any sum or do any act at a particular indicated time or within an indicated period, it is understood that time is of the essence. Any obligations of a party accruing prior to the expiration or termination of this Lease shall survive the expiration or termination of this Lease, and such party shall promptly perform all such obligations whether or not this Lease has expired.

Accordingly, this Lease shall be construed neither for nor against Landlord or Tenant, but shall be given a fair and reasonable interpretation in accordance with the meaning of its terms and the intent of the parties. This Lease shall not be binding or effective until each of the parties hereto has executed and delivered an original counterpart hereof to each other. No contractual or other rights shall exist between Landlord and Tenant with respect to the Tenant Space until both have executed and delivered this Lease, notwithstanding that Landlord has delivered to Tenant an unexecuted copy of this Lease. The submission of this Lease to Tenant shall not constitute the grant of an option for the Tenant to lease, or otherwise create any interest by Tenant in, the Tenant Space. The execution of this Lease by Tenant and return to Landlord shall not be binding upon Landlord, notwithstanding any time interval, until Landlord has, in fact, executed and delivered this Lease to Tenant.

     17.14 Force Majeure. Except for the extent to which a party’s obligations or rights are expressly stated herein to apply notwithstanding the effect of Force Majeure events, a party shall incur no liability to the other party with respect to, and shall not be responsible for any failure to perform, any of its obligations hereunder (other than payment obligations or obligations that may be cured by the payment of money (e.g., maintaining insurance)) if such failure is caused by a Force Majeure event. The amount of time for a party to perform any of its obligations (other than payment obligations) shall be extended by the amount of time such party is delayed in performing such obligation by reason of any Force Majeure event.

     17.15 No Partnership or Joint Venture; No Third Party Beneficiaries. Nothing contained in this Lease shall be deemed or construed to create the relationship of principal and agent, or partnership, or joint venturer, or any other relationship between Landlord and Tenant other than landlord and tenant. Landlord shall have no obligations hereunder to any person or entity other than Tenant, and no other parties shall have any rights hereunder as against Landlord.

     17.16 Access by Landlord. Landlord, Landlord’s agents and employees shall have the right to enter upon any and all parts of the Tenant Space at any reasonable time upon prior reasonable oral or written notice (except in the case of an emergency when no prior notice shall be required, and except as otherwise expressly set forth below) to examine the condition thereof, to clean, to make any repairs, alterations or additions required to be made by Landlord hereunder, to show the Tenant Space to prospective purchasers or prospective or current mortgage lenders (in either case only upon 48 hours’ prior oral or written notice), to show the Tenant Space to prospective tenants (only during the last three (3) months of the Term, and only upon 48 hours’ prior oral or written notice), to determine whether Tenant is complying with all of its obligations under this Lease, and/or to exercise any of Landlord’s rights or remedies hereunder.

first obtaining the prior written consent of the other party, except that each party shall have the right to disclose such information for valid business, legal and accounting purposes and/or if advisable under any applicable securities laws regarding public disclosure of business information. Landlord acknowledges that Tenant will include this Lease in filings with governmental agencies, including without limitation the Securities and Exchange Commission, but only to the extent that such inclusion and/or disclosure is required under applicable securities laws.

MASSACHUSETTS STATE LAW PROVISIONS

     1. REMEDIES FOR EVENTS OF DEFAULT.

          1.1 Landlord’s Right to Terminate Upon Tenant Default. This Lease and the Term and estate hereby granted and the demise hereby made are subject to the limitation that if and whenever any Event of Default shall occur, Landlord may, at Landlord’s option, in addition to all other rights and remedies given hereunder or by law or equity, do any one or more of the following without notice or demand other than a notice to quit, any such notice or demand being hereby waived other than a notice to quit:

               1.1.1 Terminate this Lease, in which event Tenant shall immediately surrender possession of the Tenant Space to Landlord.

               1.1.2 Enter upon and take possession of the Tenant Space and expel or remove Tenant and any other occupant therefrom, with or without having terminated this Lease.

               1.1.3 Alter locks and other security devices at the Tenant Space.

               1.1.4 Terminate any and all agreements, subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant, with Landlord or with third parties, and affecting the Tenant Space or any part of the Meet-Me Room or the Building.

          1.2 No Surrender or Merger. Exercise by Landlord of any one or more remedies hereunder granted or otherwise available shall not be deemed to be an acceptance of surrender of all or any part of the Tenant Space by Tenant, whether by agreement or by operation of law, it being understood that such surrender can be effected only by the written agreement of Landlord and Tenant. No such alteration of security devices and no removal or other exercise of dominion by Landlord over the property of Tenant or others on or about the Tenant Space shall be deemed unauthorized or constitute a conversion, Tenant hereby consenting, after any termination of this Lease or entry for possession following delivery of a notice to quit from Landlord to Tenant, to the aforesaid exercise of dominion over Tenant’s property within the Building. All claims for damages by reason of such re-entry and/or possession and/or alteration of locks or other security devices are hereby waived, as are all claims for damages by reason of any distress warrant, forcible detainer proceedings, sequestration proceedings or other legal process. Tenant agrees that any re-entry by Landlord may be pursuant to judgment obtained in forcible detainer proceedings or other legal proceedings or without the necessity for any legal proceedings, as Landlord may elect, and Landlord shall not be liable in trespass or otherwise.

          1.3 Damages Upon Default. If Landlord elects to terminate this Lease by reason of an Event of Default, then, notwithstanding such termination, Landlord may hold Tenant liable for all rental and other indebtedness accrued to the date of such termination, plus, at Landlord’s election, either:

          (i) such rental and other indebtedness as would otherwise have been required to be paid by Tenant to Landlord during the period following termination of the Term of this Lease measured from the date of such termination by Landlord until the expiration of the Term of this Lease (had Landlord not elected to terminate this Lease on account of such Event of Default) diminished by any net sums thereafter received by Landlord through reletting the Tenant Space during said period (after deducting expenses incurred by Landlord as provided in Section 1.5 below), or

          (ii) the amount (discounted to present value) by which, at the time of the termination of this Lease (or at any time thereafter if Landlord shall have initially elected damages under clause (i) above), (x) the aggregate of the rent and other charges projected over the period

commencing with such termination and ending on the last day as of which the Term of the Lease would have expired, but for such Event of Default, exceeds (ii) the aggregate projected market rental value (including other charges) for the Tenant Space for such period.

Actions to collect amounts due by Tenant provided for in clause (i) of this Section 1.3 may be brought from time to time by Landlord during the aforesaid period, on one or more occasions, without the necessity of Landlord’s waiting until the expiration of such period, and in no event shall Tenant be entitled to any excess of rental (or rental plus other sums) obtained by reletting over and above the rental provided for in this Lease.

          1.4 Repossession of Tenant Space. If Landlord elects to repossess the Tenant Space without terminating this Lease, Tenant shall be liable for and shall pay to Landlord all rental and other indebtedness accrued to the date of such repossession, plus Rent required to be paid by Tenant to Landlord during the remainder of the Term of this Lease until the expiration of the Term of this Lease, diminished by any net sums thereafter received by Landlord through reletting the Tenant Space during said period (after deducting expenses incurred by Landlord as provided in Section 1.5 below). In no event shall Tenant be entitled to any excess of any rental obtained by reletting over and above the rental herein reserved. Actions to collect amounts due by Tenant as provided in this Section 1.4 may be brought from time to time, on one or more occasions, without the necessity of Landlord’s waiting until the expiration of the Term of this Lease.

          1.5 Landlord’s Expenses. Upon an Event of Default, Tenant shall also be liable for and shall pay to Landlord, in addition to any sum provided to be paid pursuant to this Lease: (i) the reasonable costs and expenses of securing new tenants, including expenses for refixturing, alterations and other costs in connection with preparing the Tenant Space for the new tenant and any reasonable or necessary alterations, (ii) the cost of removing and storing Tenant’s or other occupant’s property, and (iii) all reasonable expenses incurred by Landlord in enforcing Landlord’s remedies, including actual attorneys’ fees. Past due rental and other past due payments shall bear interest from maturity at the Default Rate (as defined in Section 3.5 of this Lease) until paid.

          1.6 Cumulative Remedies; Equitable Relief. The specific remedies to which Landlord may resort under the provisions of this Lease are cumulative and are not intended to be exclusive of any other remedies or means of redress to which it may be lawfully entitled in case of any breach or threatened breach by Tenant of any provisions of this Lease.

          1.7 Reletting. Landlord agrees to use reasonable efforts to relet the Tenant Space after Tenant vacates the Tenant Space in the event that the Lease is terminated following an Event of Default by Tenant hereunder. Marketing of the Tenant Space in a manner similar to the manner in which Landlord markets other premises within Landlord’s control in the Building shall be deemed to have satisfied Landlord’s obligation to use “reasonable efforts.” If such waiver is not effective under then applicable law or if Landlord otherwise elects, at Landlord’s sole option, to attempt to relet all or any part of the Tenant Space, Tenant agrees that, in any event, Landlord has no obligation to: (i) relet the Tenant Space prior to leasing any other space within the Building; or (ii) relet the Tenant Space (A) at a rental rate or otherwise on terms below market, as then determined by Landlord in its sole discretion; (B) to any entity not satisfying Landlord’s then standard financial credit risk criteria; (C) for a use (1) not consistent with Tenant’s use prior to default; (2) which would violate then applicable law or any restrictive covenant or other lease affecting the Building; (3) which would impose a greater burden upon the Building’s facilities; or (4) which would involve any use of Hazardous Materials not in compliance with applicable Legal Requirements; (iii) solicit or entertain negotiations with any other prospective tenants for the Tenant Space until Landlord obtains full and complete possession of the Tenant Space, including, without limitation, the final and unappealable legal right to re-let the Tenant Space free of any claim of Tenant; or (iv) make any alterations to the Tenant Space or the Building or otherwise incur any costs in connection with any such reletting, unless Tenant unconditionally delivers to Landlord, in good and sufficient funds, the full amount thereof in advance.

          1.8 Landlord’s Right to Cure. All covenants and agreements to be performed by Tenant under this Lease shall be performed by Tenant at Tenant’s sole cost and expense. If Tenant should fail to make any payment (other than Base Rent) or cure any default hereunder within the time herein permitted, Landlord, without being under any obligation to do so, without thereby waiving such default and in addition to and without prejudice to any other right or remedy of Landlord, may make such payment and/or remedy such other default for the account of Tenant (and enter the Tenant Space for such purpose), and thereupon Tenant shall be obligated to, and hereby agrees to, pay to Landlord as Additional Rent, within ten (10) days following Landlord’s demand therefor, all costs, expenses and disbursements (including actual attorneys’ fees) incurred by Landlord in taking such remedial action, plus an administrative fee of ten percent (10%) of such amount.

          2. CALCULATION OF CHARGES. Landlord and Tenant are knowledgeable and experienced in commercial transactions and agree that the provisions set forth in this Lease for determining charges, amounts and additional rent payable by Tenant (including, without limitation, payments under Section 3.4) are commercially reasonable and valid even though such methods may not state a precise mathematical formula for determining such charges.

          (3) In the event that Tenant is entitled to an Outage Credit or Partial Outage Credit, the Outage Credit or Partial Outage Credit, as applicable, shall be applied as a credit towards Tenant’s Base Rent due in the immediately following month of the Term; provided, however, in the event that an Outage Credit or Partial Outage Credit accrues during the final month of the Term, Landlord will pay to Tenant the amount of the Outage Credit or Partial Outage Credit within thirty (30) days following the expiration of the Term. For the avoidance of doubt, Landlord and Tenant acknowledge and agree that, in the event the Interruption of Landlord’s Essential Services and/or Loss of Redundancy affects fewer than all of the Suites, the Outage Credit(s) (or Partial Outage Credit, as applicable) to which Tenant is entitled shall be calculated based upon the Base Rent for the affected Suite(s) only.

3. Termination Rights.

     A. Continuous Outage Termination Right. In the event of a Continuous Outage, Tenant may terminate this Lease by timely delivery of the Continuous Outage Termination Notice to Landlord. Tenant’s failure to timely deliver Tenant’s Continuous Outage Termination Notice shall automatically extinguish Tenant’s right to terminate this Lease with respect to that particular Continuous Outage. For the avoidance of doubt, Landlord and Tenant acknowledge and agree that Tenant’s right to terminate this Lease under this Section 3.A applies to the entire Tenant Space, and does not apply individually to the Suite in which the Continuous Outage occurred.

     B. Chronic Outage Termination Right. In the event of a Chronic Outage, Tenant may terminate this Lease by timely delivery of the Chronic Outage Termination Notice to Landlord. Tenant’s failure to timely deliver Tenant’s Chronic Outage Termination Notice shall automatically extinguish Tenant’s right to terminate this Lease with respect to that particular Chronic Outage. For the avoidance of doubt, Landlord and Tenant acknowledge and agree that Tenant’s right to terminate this Lease under this Section 3.B applies to the entire Tenant Space, and does not apply individually to the Suite in which the Chronic Outage occurred.

4. Remedies Exclusive. Tenant agrees that Tenant’s entitlement to Outage Credits, Partial Outage Credits and termination rights, as expressly set forth in this Exhibit “F”, shall be Tenant’s sole and exclusive remedies with regard to each Interruption of Landlord’s Essential Services and/or Loss of Redundancy.
