     1.7 Tenant’s Data Center Expansion Right. Subject to the terms and conditions set forth in this Section 1.7, Tenant shall have a one-time right to request that Landlord demise to Tenant additional Data Center space in the Building (“Data Center Expansion Area”) which would provide Tenant with approximately an additional 500 KW of capacity. Tenant shall only have the right to lease a Data Center Expansion Area if Landlord determines, in Landlord’s sole, but bona fide, business judgment, that a Data Center Expansion Area and the associated additional power capacity is available for lease to Tenant. Tenant hereby acknowledges that the availability of any Data Center Expansion Area depends upon both: (i) the availability of premises in the Building for such use by Tenant, and (ii) the availability of the additional power capacity necessary to service such Data Center Expansion Area, and the availability of additional power is dependent upon Landlord’s ability to purchase such capacity from a utility company.

          1.7.1 If Tenant desires to lease a Data Center Expansion Area, Tenant must give written notice (“Data Center Expansion Request”) to Landlord requesting that Landlord advise Tenant as to whether a Data Center Expansion Area is available for lease to Tenant.

          1.7.2 Landlord shall, within fifteen (15) calendar days after Landlord receives a Data Center Expansion Request from Tenant, give Tenant written notice (“Landlord’s Data Center Offer”) advising Tenant as to whether a Data Center Expansion Area is available for lease to Tenant on or about a date one hundred eighty (180) calendar days after Landlord receives such Data Center Expansion Request, and, if so: (i) the location of the Data Center Expansion Area, (ii) the estimated Commencement Date with respect to the Data Center Expansion Area, (iii) the Base Rent and other costs which would be payable by Tenant in connection with Tenant’s demise of the Data Center Expansion Area, both during the Initial Term (if applicable), the First

Extension Term, and the Second Extension Term, and (iv) and such other terms and conditions as may be applicable to Tenant’s demise of the Data Center Expansion Area. The Base Rent for a Data Center Expansion Area shall be based upon the Prevailing Base Rent, as defined in Section 2.3.3, of the Data Center Expansion Area, as determined by Landlord in the exercise of its bona fide business judgment (except that Tenant shall not have the right to submit Landlord’s determination to Fair Market Rent Arbitration in accordance with Section 2.3.6); such Base Rent and other costs shall take into account, without limitation, costs which Landlord has incurred, or will have to incur, both capital cost and on-going costs, in order to obtain the power capacity from a utility company necessary to serve the Data Center Expansion Area; and such other terms and conditions shall be based upon the terms and conditions which are then applicable to leases then being executed for comparable data center space in the Building. Tenant shall take the Data Center Expansion Area in “as-is” condition (i.e. Landlord shall have no obligation to prepare the Data Center Expansion Area for Tenant’s use and occupancy). If Tenant leases the Data Center Expansion Area, Tenant shall not be entitled to any additional reserved Parking Spaces; however, Tenant shall be entitled to use up to three and one-half (3.5) common parking spaces in the Parking Areas per one thousand (1,000) rentable square feet of the Data Center Expansion Area in accordance with Exhibit “G”.

          1.7.3 If Landlord advises Tenant that a Data Center Expansion Area is available for lease to Tenant, then: (i) Tenant may lease the Data Center Expansion Area offered in Landlord’s Data Center Offer by giving written notice (“Data Center Expansion Exercise Notice”) to Landlord on or before the date fifteen (15) calendar days after Tenant receives the Landlord’s Data Center Offer, (ii) if Tenant timely gives Landlord a Data Center Expansion Exercise Notice, then Tenant shall lease the Data Center Expansion Area from Landlord for a Term expiring contemporaneously with the expiration of the Term with respect to the Tenant Space initially demised to Tenant, upon the terms and conditions set forth in Landlord’s Data Center Offer, and otherwise upon all of the same terms and conditions applicable to Tenant’s demise of the Tenant Space initially demised to Tenant, to the extent not inconsistent with the provisions of Landlord’s Data Center Offer, and Tenant shall have no further right to lease additional Data Center Expansion Area pursuant to this Section 1.7, and (iii) if Tenant does not timely give Landlord a Data Center Expansion Exercise Notice, Tenant shall have no further right to lease additional space pursuant to this Section 1.7.

          1.7.4 If Landlord advises Tenant that a Data Center Expansion Area is not available for lease to Tenant, then Tenant shall have the right, from time to time (but subject to the provisions of this Section 1.7) give Landlord subsequent Data Center Expansion Exercise Notices, but not more often than one time every three months.

          1.7.5 Tenant shall have the right to lease a Data Center Expansion Area only with respect to the entirety of such Data Center Expansion Area. If Tenant duly exercises its right to lease a Data Center Expansion Area, Landlord and Tenant shall execute an amendment reflecting such exercise. Notwithstanding anything to the contrary herein, any attempted exercise by Tenant of its right to lease a Data Center Expansion Area shall, at the election of Landlord, be invalid, ineffective, and of no force or effect if, on the date on which Tenant delivers a Data Center Expansion Exercise Notice, or on the Commencement Date with respect to such Data Center Expansion Area, either: (i) there shall be an uncured Event of Default by Tenant under this Lease, or (ii) the Lease is no longer in full force or effect.

     1.8 Tenant’s Right of First Offer to Lease Additional Office Area. Subject to the provisions of this Section 1.8, Tenant shall have the following one-time right to lease the Office Expansion Area, as hereinafter defined, when the Office Expansion Area becomes available for lease to Tenant.

          1.8.1 “Office Expansion Area” shall be defined as any area in the Building, containing approximately 10,000 rentable square feet, when such area becomes available for lease to Tenant during the Term of this Lease. The Office Expansion Area shall be deemed to be “available for lease to Tenant” when Landlord, in its reasonable judgment, determines that such area will become available for leasing to Tenant (i.e. when Landlord determines that (i) the lease of the tenant of the Office Expansion Area will terminate and such tenant will vacate such Office Expansion Area, (ii) the rights of another tenant of the Building, Comverse, Inc. (“Comverse”), to lease such premises as of the Effective Date of this Lease have lapsed unexercised or have been waived, and (iii) Landlord intends to offer such area for lease). Landlord represents to Tenant that Comverse has a right of first offer to lease any separately demised premises on the second floor of the Building. In no event shall Tenant have any rights under this Section 1.8 on or after the date twelve (12) months prior to the expiration of the Term of the Lease (i.e. Landlord shall have no obligation to give Landlord’s Office Offer, as hereinafter defined, to Tenant on or after the date twelve (12) months prior to the expiration of the Term of the Lease).

          1.8.2 Landlord shall give Tenant written notice (“Landlord’s Office Offer”) at the time that Landlord determines, as aforesaid, that the Office Expansion Area will become available for lease to Tenant. Landlord’ s Office Offer shall set forth: (i) the location of the Office Expansion Area, (ii) the estimated Commencement Date with respect to the Office Expansion Area, (iii) the Base Rent and other costs which would be payable by Tenant in connection with Tenant’s demise of the Office Expansion Area, both during the Initial Term (if applicable), the First Extension Term, and the Second Extension Term, and (iv) and such other terms and conditions as may be applicable to Tenant’s demise of the Office Expansion Area. The Base Rent for an Office Expansion Area shall be based upon the Prevailing Base Rent, as defined in Section 2.3.3, of the Office Expansion Area, as determined by Landlord in the exercise of its bona fide business judgment (except that Tenant shall not have the right to submit Landlord’s determination to Fair Market Rent Arbitration in accordance with Section 2.3.6); and such other terms and conditions shall be based upon the terms and conditions which are then applicable to leases then being executed for comparable office space in the Building. Tenant shall take the Office Expansion Area in “as-is” condition (i.e. Landlord shall have no obligation to prepare the Office Expansion Area for Tenant’s use and occupancy). If Tenant leases the Office Expansion Area, Tenant shall not be entitled to any additional reserved Parking Spaces; however, Tenant shall be entitled to use up to three and one-half (3.5) common parking spaces in the Parking Areas per one thousand (1,000) rentable square feet of the Office Expansion Area in accordance with Exhibit “G”.

          1.8.3 Tenant may lease the Office Expansion Area offered in Landlord’s Office Offer by giving written notice (“Office Expansion Exercise Notice”) to Landlord on or before the date fifteen (15) days after Tenant receives Landlord’s Office Offer, (ii) if Tenant timely gives Landlord a Office Expansion Exercise Notice, then Tenant shall lease the Office Expansion Area from Landlord for a Term expiring contemporaneously with the expiration of the Term with respect to the Tenant Space initially demised to Tenant, upon the terms and conditions set forth in

Landlord’s Office Offer, and otherwise upon all of the same terms and conditions applicable to Tenant’s demise of the OS Tenant Space initially demised to Tenant, to the extent not inconsistent with the provisions of Landlord’s Office Offer, and Tenant shall have no further right to lease additional Office Expansion Area pursuant to this Section 1.8, and (iii) if Tenant does not timely give Landlord a Office Expansion Exercise Notice, Tenant shall have no further right to lease additional space pursuant to this Section 1.8.

          1.8.4 Notwithstanding anything to the contrary herein contained, Tenant’s rights to lease any Office Expansion Area under this Section 1.8 shall be subject and subordinate to the rights (whether expansion rights, rights of first refusal and/or rights of first offer) of Comverse existing on the Effective Date of this Lease.

          1.8.5 Tenant shall have the right to lease an Office Expansion Area only with respect to the entirety of such Office Expansion Area. If Tenant duly exercises its right to lease an Office Expansion Area, Landlord and Tenant shall execute an amendment reflecting such exercise. Notwithstanding anything to the contrary herein, any attempted exercise by Tenant of its right to lease an Office Expansion Area shall, at the election of Landlord, be invalid, ineffective, and of no force or effect if, on the date on which Tenant delivers a Office Expansion Exercise Notice, or on the Commencement Date with respect to such Office Expansion Area, either: (i) there shall be an uncured Event of Default by Tenant under this Lease, or (ii) the Lease is no longer in full force or effect.

     1.9 Licenses and Permits. Landlord shall, at Landlord’s cost, obtain all licenses, approvals, permits and authorizations required by applicable federal, state, and local laws and regulations that Landlord is required to have in order to perform the Landlord’s Essential Services and to perform Landlord’s Installations. Landlord shall provide Tenant with all such licenses, approvals, permits and authorizations within ten (10) business days after Landlord’s receipt of Tenant’s request therefore.

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 shall use commercially reasonable efforts to satisfy the Commencement Date Conditions prior to the Target Commencement Date. Landlord and Tenant acknowledge and agree that, by virtue of Landlord’s delivery of the Commencement Date Notice to Tenant, Landlord shall be deemed to have delivered the Tenant Space to Tenant, and Tenant shall be deemed to have accepted the same.

          2.2.1 Failure to Meet Commencement Date Conditions. In the event that the Commencement Date Conditions have not been completed by the Target Commencement Date, subject to extension by virtue of Force Majeure, Landlord shall not be deemed in default hereunder, and the Commencement Date shall be postponed, as Tenant’s sole and exclusive

alternative remedies, until the date on which the Commencement Date Conditions have occurred. Notwithstanding the foregoing:

               2.2.1.1 If the Commencement Date Conditions have not occurred prior to the Outside Liquidated Damages Date, subject to extension by virtue of Force Majeure, Tenant shall receive a credit (“Rent Credit”) of [***] days of Rent (calculated using the Rent amounts which would have been payable had the Tenant Space been timely delivered) for each day between the Outside Liquidated Damages Date (as extended by virtue of Force Majeure) and the date on which the Commencement Date Conditions occur, provided however that in no event shall the amount of the Rent Credit exceed 30 days of Rent (calculated using the Rent amounts which would have been payable had the Tenant Space been timely delivered); or

               2.2.1.2 If the Commencement Date Conditions have not occurred prior to the Outside Completion Date, subject to extension by virtue of Force Majeure, Tenant shall have the right to terminate this Lease, provided that:

(a) Tenant notifies Landlord of such termination prior to the earlier to occur of: (1) completion of the Commencement Date Conditions; or (2) ten (10) business days after the Outside Completion Date; and

(b) Landlord has not caused the Commencement Date Conditions to have been completed within five (5) days after its receipt of such notice of termination from Tenant.

If (aa) the Commencement Date Conditions are completed prior to Tenant’s exercise of the foregoing termination right, (bb) the Commencement Date Conditions are completed within ten (10) days after Tenant’s exercise of the foregoing termination right, or (cc) Tenant shall fail to exercise such termination right within ten (10) days after the Outside Completion Date, then such termination right shall, in any such event, be deemed to have expired and shall, thereafter, be of no further force or effect.

     2.3 Extension Options.

          2.3.1 Subject to and in accordance with the terms and conditions of this Section 2.3, Tenant shall have the following options (“Extension Options”) to extend the Term of the Lease.

	First Extension Term:		Three (3) years (months 51-86)
	Second Extension Term:		Three (3) years (months 87-122)
	Third Extension Term:		Five (5) years (months 123-182)
	Fourth Extension Term:		Five (5) years (months 183-242)

Tenant’s right to extend the Term of the Lease with respect to any Extension Term shall be conditioned upon Tenant having timely and properly exercised its right to extend the Term of the Lease for all prior Extension Terms. Notwithstanding the foregoing, in lieu of Tenant’s

[***]		Information has been omitted and filed separately with the Securities and Exchange Commission. Confidential Treatment has been requested with respect to the omitted portions.

exercising its right to extend the Term of the Lease for the five (5) year Third Extension Term or (if Tenant has previously exercised its right to extend the Term of the Lease for the Third Extension Term) in lieu of Tenant’s exercising its right to extend the Term of the Lease for the five (5) year Fourth Extension Term, Tenant may extend the term of the Lease for a one (1) year Extension Term (“One Year Extension Term”). If Tenant exercise its right to extend the Term of the Lease for the One Year Extension Term, Tenant shall have no further right to extend the Term of the Lease.

          2.3.2 Each Extension Term shall be upon all of the same terms, conditions and provisions applicable to the then-current Term of this Lease (except as provided otherwise herein). Tenant shall have no further options to extend the Term, except as expressly set forth in this Section 2.3.

          2.3.3 The monthly Extension Term Base Rent payable with respect to the Tenant Space for each Extension Term shall be as follows:

First Extension Term:			See Item 8 of the Basic Lease Information
Second Extension Term:			See Item 8 of the Basic Lease Information
Third and Fourth Extension Terms:
			The monthly Extension Term Base Rent payable with respect to the Tenant Space for each of the Third Extension Term and the Fourth Extension Term shall be equal to [***] ([***]%) percent of the then (i.e. as of the commencement of the Extension Term in question) prevailing base rent then being charged by Landlord for comparable space (“Prevailing Base Rent”) in the Building for new leases (or if there are new leases of comparable data center space then being entered into in the Building, then for comparable space in the Northern Market, as shown on Exhibit “I”), taking into consideration all relevant factors, including the quality, size, utility and location thereof, the length of such Extension Term, the credit standing of Tenant, the amenities provided to Tenant, the Tax Base Year, and any economic concessions given to tenants, such as free rent and allowances; provided, however, that in no event shall the monthly Base Rent payable by Tenant during the first year of either the Third Extension Term or the Fourth Extension Term be less than [***] percent ([***]%) of the monthly Base Rent that was payable during the last month immediately preceding the commencement of such Extension Term (“Floor Base Rent”); and provided further that, once the Base Rent has been determined in accordance with this Section 2.3 with regard to the first year of an Extension Term, the monthly Base Rent for each subsequent year of such Extension Term

[***]		Information has been omitted and filed separately with the Securities and Exchange Commission. Confidential Treatment has been requested with respect to the omitted portions.

Confidential Treatment Requested by Carbonite, Inc.

		shall be increased hereunder as of the first (1st) day of each such subsequent year to be equal to [***] percent ([***]%) of the monthly Base Rent for the immediately preceding year of such Extension Term.
One Year Extension Term:		The monthly Extension Term Base Rent payable with respect to the Tenant Space for the One Year Extension Term shall be equal to [***] percent ([***]%) of the Base Rent payable for the month immediately preceding the commencement of the One Year Extension Term.

          2.3.4 With respect to the First Extension Option, the Second Extension Option and the One Year Extension Option, Tenant may exercise each such Extension Option only by delivering an Extension Option Exercise Notice to Landlord at least nine (9) calendar months (and not more than twelve (12) calendar months) prior to the then applicable expiration date of the Term, specifying that Tenant is irrevocably exercising its Extension Option so as to extend the Term of this Lease by an Extension Term on the terms set forth in this Section 2.3.

          2.3.5 With respect to the Third Extension Option and the Fourth Extension Option, Tenant may exercise each such Extension Option only by delivering to Landlord a written notice (an “Initial Extension Option Notice”) at least nine (9) calendar months (and not more than twelve (12) calendar months) prior to the expiration of the immediately preceding Extension Term, exercising (subject to the provisions of this Section 2.3.5), Tenant’s right to extend the Term of the Lease for either the Third Extension Option or the Fourth Extension Option, as the case may be, pursuant to this Section 2.3. Within thirty (30) calendar days after Tenant delivers such Extension Option Interest Notice, Landlord will advise Tenant of Landlord’s determination of Base Rent payable by Tenant with respect to the Extension Term in question (“Landlord’s Option Notice”). If either: (i) the Base Rent designated by Landlord for the Extension Term in question is equal to the applicable Floor Base Rent for such Extension Term, or (ii) if Landlord and Tenant agree on the Option Rent for the Extension Term in question within thirty (30) calendar days after the date Landlord provides Tenant with Landlord’s Option Notice (the “Negotiation Period”), then either the Floor Base, or the Base Rent agreed by the Parties shall be the Base Rent for the Extension Term in question. If, however, the Base Rent designated by Landlord for the Extension Term in question exceeds the applicable Floor Base Rent for such Extension Term and if Landlord and Tenant cannot agree on the rental rate for the Extension Term during the Negotiation Period, then, as an alternative, Tenant may elect to have the Base Rent for such Extension Term be determined in accordance with the arbitration method described in Section 2.3.6 by providing Landlord, within ten (10) business days after the expiration of the Negotiation Period, with Tenant’s binding notice (“Extension Option Exercise Notice”) of Tenant’s election to extend the Term of this Lease for such Extension Term with the Base Rent for such Extension Term being determined pursuant to the arbitration method (“Fair Market Rent Arbitration”) described in Section 2.3.6 below.

          2.3.6 Fair Market Rent Arbitration. The provisions this Section 2.3.6 shall only apply with respect to the determination of Prevailing Base Rent payable with respect to the Third Extension Term and/or the Fourth Extension Term, in the circumstances set forth in Section 2.3.5. Within ten (10) business days after Tenant’s delivery to Landlord of Tenant’s

[***]		Information has been omitted and filed separately with the Securities and Exchange Commission. Confidential Treatment has been requested with respect to the omitted portions.

Confidential Treatment Requested by Carbonite, Inc.

Option Exercise Notice with respect to the Third Extension Term or the Fourth Extension Term, as the case may be, pursuant to which Tenant elects to have Base Rent determined pursuant to Fair Market Rent Arbitration (the “Appointment Deadline”), each party shall give written notice to the other setting forth the name and address of the Disinterested Expert selected by such party, who has agreed to act in such capacity, to determine the Prevailing Base Rent for such Extension Term. If either party shall fail to select a Disinterested Expert within the required time period, then the Disinterested Expert selected by the other Party shall determine the Prevailing Base Rent. Each Disinterested Expert shall thereupon independently make its determination of the Prevailing Base Rent within thirty calendar (30) days after the Appointment Deadline (each, an “Initial Expert Determination”). If either Disinterested Expert shall fail to make an Initial Expert Determination of the Prevailing Base Rent within thirty (30) days after the Appointment Deadline, then the Initial Expert Determination of the other Disinterested Expert (to the extent that such Disinterested Expert makes such Initial Expert Determination within such thirty (30) day period) shall be deemed the Prevailing Base Rent. If the two (2) Disinterested Experts’ Initial Expert Determination are not the same, but the higher of such two (2) values is not more than [***] percent ([***]%) of the lower of such values, then the Prevailing Base Rent shall be deemed to be the average of the two (2) values. If, however, the higher of such two (2) values is more than [***] percent ([***]%) of the lower of such values, then the two (2) Disinterested Experts shall jointly appoint a third (3^rd) Disinterested Expert (the “3^rd Expert”) within ten (10) days after the second (2nd) of the two (2) Initial Expert Determinations has been rendered and delivered to the other Party. The 3^rd Expert shall independently choose which of the Initial Expert Determinations is the more accurate with regard to Prevailing Base Rent, and the Initial Expert Determination chosen by the 3^rd Expert shall be deemed to be the Prevailing Base Rent for the Extension Term. The 3^rd Expert shall only choose from between the Initial Expert Determinations provided by each of the other Disinterested Experts and shall not be afforded the opportunity to render an independent Initial Expert Determination. For the purposes hereof, “Disinterested Expert” shall mean a broker who has been regularly engaged in the business of datacenter leasing in the Northern Market for at least the five (5) years immediately preceding such person’s appointment hereunder. Each Party shall pay for the cost of its Disinterested Expert and one-half of the cost of any 3^rd Expert. If the Base Rent for the Third Extension Term or the Fourth Extension Term, as the case may be, shall not have been determined prior to the commencement of such Extension Term, then Tenant shall commence to pay Base Rent with respect to such Extension Term based upon the applicable Floor Base Rent for such Extension Term, and, after such Base Rent is determined, Tenant shall, within thirty (30) calendar days after billing, pay to Landlord any underpayment of Base Rent.

          2.3.7 In the event that Tenant shall duly exercise an Extension Option, the Term shall be extended to include the applicable Extension Term (and all references to the Term in this Lease shall be deemed to refer to the Term specified in Item 5 of the Basic Lease Information, plus all Extension Terms properly exercised by Tenant). In the event that Tenant shall fail to deliver an Extension Option Exercise Notice, or an Initial Extension Option Notice, as the case may be, within the applicable time period specified herein for the delivery thereof, time being of the essence, at the election of Landlord, Tenant shall be deemed to have forever waived and relinquished such Extension Option, and any other options or rights to renew or extend the Term effective after the then applicable expiration date of the Term shall terminate and shall be of no further force or effect.

[***]		Information has been omitted and filed separately with the Securities and Exchange Commission. Confidential Treatment has been requested with respect to the omitted portions.

          2.3.8 Tenant shall have the right to exercise any Extension Option only with respect to the entire Tenant Space leased by Tenant at the time that Tenant delivers the applicable Extension Option Exercise Notice. 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, Initial Extension Option Notice, or on the date on which the Extension Term is scheduled to commence, either: (i) there shall be an uncured Event of Default by Tenant under this Lease, or (ii) the Lease is no longer in full force or effect.

3. BASE RENT AND OTHER CHARGES.

     3.1 Base Rent. Tenant shall pay Base Rent to Landlord throughout the Term of 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) 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; and

(b) if the Term of this Lease is terminated on a date other than the last day of a calendar month, any prepaid Base Rent and Additional Rent shall be refunded to Tenant on a per diem and prorated basis for each day during the calendar month after the effective date of termination for which Tenant has paid Base Rent and Additional Rent, to the extent that such overpayment exceeds any amounts then due from Tenant to Landlord.

Tenant shall not pay any installment of Rent more than one (1) month in advance.

     3.2 Installation Fee. Intentionally Deleted.

     3.3 Payments Generally. Base Rent and all forms of Additional 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). No receipt of money by Landlord from Tenant after the termination of this Lease shall reinstate, continue or extend the Term of this Lease. 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.

     3.4 Late Payments. Landlord and Tenant agree that if Landlord has not received any payment of Rent on or before the Delinquency Date, 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. Notwithstanding the foregoing, Landlord hereby agrees to waive the Late Charge with respect to the first late payment in any twelve (12) month period. 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 pay for all electricity and/or other utilities (e.g., chilled water) serving, provided to and/or used in, or for, the Tenant Space. Tenant shall pay each Tenant’s Utility Payment to Landlord, as Additional Rent, within thirty (30) days of receipt of each Tenant’s Utility Payment invoice. The formulas described in Section 3.5.1, below, has been designed to capture Tenant’s Shared Mechanical Payment. If, however, Landlord reasonably determines (i.e. based upon the report of a reputable engineer) that the method of calculating any of Tenant’s Shared Mechanical Payments is inadequate to capture the costs related to the Shared Mechanical Equipment that should otherwise be attributable to the Tenant Space, Landlord may utilize a different formula/calculation, as necessary, to appropriately capture such costs. In such event, the applicable Tenant’s Shared Mechanical Payment shall, from and after notice to Tenant be the cost calculated using such modified formula/calculation. In such event, Landlord and Tenant shall execute an amendment to this Lease reflecting such modification; provided, however, that the execution of such amendment shall not be necessary to effect the modification. Additionally, in the event that Landlord determines that it is no longer commercially impractical to separately meter some or all of the utility costs related to some or all of the Shared Mechanical Equipment, then Landlord may cause the relevant Shared Mechanical Equipment to be separately metered to the Tenant Space. In such event, Tenant’s Utility Payment related to the newly metered Shared Mechanical Equipment shall thereafter be the separately metered cost of the shared utilities provided to, serving and/or used in, the Tenant Space by such equipment based upon the Shared Mechanical Metering Equipment (i.e., such payment would then be a Tenant’s Separately Metered Utility Payment). Landlord and Tenant acknowledge and agree that the utility costs for which Tenant shall be responsible include the actual cost of all utilities (including electricity) serving, provided to and/or used in the UPS Room and the Pump Room. Landlord hereby represents to Tenant that Tenant’s Utility Payment is based upon the actual cost to Landlord of the utilities in question and does not include any profit or mark-up to Landlord.

          3.5.1 Calculation of Tenant’s Utility Payments.

     For the purposes of the following equation:

          (1) the applicable Total Power Consumption used by Shared Mechanical Equipment supporting interconnected DLR datacenters in the Building (in kW-hrs) is represented by the letter “C”.

          (2) the applicable Total UPS Power Distribution Breaker Consumption of all data centers (in kW-hrs) which use the shared mechanical equipment is represented by the letter “D”.

          (3) the applicable Premises UPS Power Distribution Breakers kW-hr is represented by the letter “A”.

          (4) the applicable Total Data Center UPS Power Distribution Breakers kW-hr is represented by the letter “B”.

          (5) the applicable Tenant’s Shared Mechanical Equipment Utility Costs Payment for Mechanical Equipment used by interconnected datacenters in the Building are represented by the letter “E”. The formula for “E” is as follows: E = C x (A/D) x utility rate for that given month (utility rate is in $/kW-hrs).

          (6) the applicable Datacenter Utility Costs are represented by the letter “N”.

During Periods of Premises Operation, the term Tenant’s Datacenter Utility Payment, as it relates to each Datacenter Utility Bill, shall mean the result of the following formula:

G = N x (A / B) +E

The cumulative payments represented by Tenant’s Datacenter Utility Payments are referred to herein, collectively, as Tenant’s Utility Payments.

     3.5.2 Periods of Premises Underutilization. Tenant acknowledges that Shared Mechanical Costs will be incurred for the operation of the Datacenter, regardless of whether there is any power being drawn in the Premises. As such, Section 3.5.1, above, notwithstanding, Landlord and Tenant hereby agree that, during Periods of Premises Underutilization, Tenant’s Shared Mechanical Payment shall be a reasonable proration of the Shared Mechanical Costs, based on the ratio that the square footage of the Premises bears to the square footage of the Datacenter.

     3.5.3 Additionally, Tenant shall pay Tenant’s proportionate share (based on power usage) of the cost of all Generator Fuel Usage, except for the extent to which such Generator Fuel Usage represents Maintenance Fuel Usage. 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 3.5.3 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.

          3.5.4 Billing Disputes and Reports. Landlord and Tenant shall exercise good faith efforts to resolve all billing disputes to their mutual satisfaction within thirty (30) calendar days.

4. TAXES.

     4.1 Taxes — Equipment. Tenant shall be liable for and shall pay at least ten (10) days 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.

     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.

     4.3 Taxes — Real Property.

          4.3.1 If the Taxes — Real Property (Actual) during any calendar year are greater than the Taxes — Real Property (Actual) applicable to the Tax Base Year, Tenant shall be obligated to pay to Landlord as Additional Rent an amount equal to Tenant’s Proportionate Share of Taxes — Real Property (Actual).

          4.3.2 Beginning with the Effective Date (or as soon thereafter as reasonably possible), Landlord shall provide to Tenant a statement of the Taxes — Real Property (Projected) for the Property for the year in which the Effective Date occurs. Tenant shall pay each Projected Real Property Tax Installment to Landlord on the first day of each month during the Term of the Lease. Until Tenant has received the statement of the Taxes — Real Property (Projected) from Landlord, Tenant shall continue to pay Projected Real Property Tax Installments to Landlord in the same amount (if any) as required for the last month of the prior calendar year. Upon Tenant’s receipt of such statement of the Taxes — Real Property (Projected), Tenant shall pay to Landlord, or Landlord shall pay to Tenant (whichever is appropriate), the difference between the amount paid by Tenant as Projected Real Property Tax Installments prior to receiving such statement and the amount payable by Tenant therefor as set forth in such statement. Landlord shall provide Tenant a statement on or before June 15 (or as soon thereafter as reasonably possible) after the end of each calendar year, showing Tenant’s Proportionate Share of Taxes — Real Property (Actual) applicable to such calendar year, as compared to the total of the Projected Real Property Tax Installments for such calendar year. If Tenant’s Proportionate Share of Taxes — Real Property (Actual) for such calendar year exceeds the aggregate of the Projected Real Property Tax Installments collected by Landlord from Tenant with regard to such calendar year, Tenant shall pay to Landlord, within thirty (30) calendar days following Tenant’s receipt of such statement, the amount of such excess. However, if Tenant’s Proportionate Share of Taxes — Real Property (Actual) for such calendar year is less than the aggregate of the Projected Real Property Tax Installments collected by Landlord from Tenant with regard to such calendar year, Landlord shall

pay to Tenant, within thirty (30) calendar days following Tenant’s receipt of such statement, the amount of such excess. Landlord shall have the right from time to time during each calendar year to revise the Taxes — Real Property (Projected), based upon Landlord’s reasonable estimate of increases or decreases in Taxes — Real Property (Projected) and provide Tenant with a revised statement thereof. Thereafter, Tenant shall pay Projected Real Property Tax Installments on the basis of the revised statement. If the Commencement Date is not the first day of a calendar year, or the expiration or termination date of this Lease is not the last day of a calendar year, then Tenant’s Proportionate Share of Taxes — Real Property (Actual) shall be prorated. The foregoing adjustment provisions shall survive the expiration or termination of the Term of this Lease. If Landlord receives an abatement of Taxes — Real Property for any fiscal/tax year in respect of which Tenant pays Tenant’s Proportionate Share of Taxes — Real Property, then Landlord shall, within thirty (30) days after Landlord actually receives the proceeds of such abatement, credit or pay to Tenant with Tenant’s Proportionate Share of the net (i.e. net of the reasonable costs incurred by Landlord in obtaining such abatement) amount of such abatement proceeds, provided however, that in no event shall Tenant receive, with respect to any fiscal tax year, more than the actual amount of Tenant’s Proportionate Share of Taxes — Real Property paid by Tenant for Landlord for such fiscal tax year.

5. SECURITY DEPOSIT. Intentionally omitted.

6. PERMITTED USE; COMPLIANCE WITH RULES AND LAWS; HAZARDOUS MATERIALS.

Landlord shall notify Tenant in writing promptly after making any changes to the Datacenter Rules and Regulations and shall provide Tenant with a copy of, or make available to Tenant electronically, the revised and current version of the Datacenter Rules and Regulations.

event shall such insurance requirements exceed those that are described on Exhibit “B-1”, attached hereto

Landlord shall provide the Casualty Repair Notice to Tenant as soon as is reasonably practicable following the Casualty Event. For the avoidance of doubt, however, such repair and reconstruction obligation shall not be deemed to include any obligation on the part of Landlord with regard to any Alteration other than Landlord’s Installations and Landlord’s OS Installations, nor any of Tenant’s Personal Property.

If, however, this Lease is not terminated pursuant to any of said Sections, then:

(a) the Base Rent and Tenant’s Proportionate Share of Taxes — Property payable by Tenant with respect to the Tenant Space shall be abated proportionately during the Repair Period-Actual to the extent that the Tenant Space (i) is unfit for use by Tenant in the ordinary conduct of Tenant’s business, and (ii) actually is not used by Tenant;

(b) the Base Rent payable by Tenant with respect to the OS Tenant Space shall be abated proportionately during the Repair Period-Actual to the extent that

     9.1.2.3 Landlord’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 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, by reason of a Taking of part of the Building or the Property:

(a) Tenant no longer has reasonable means of access to the Tenant Space, or the Tenant Space is unfit for use by Tenant in the ordinary course of Tenant’s business, 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, and

(b) Tenant no longer has reasonable means of access to the OS Tenant Space, or the OS Tenant Space is unfit for use by Tenant in the ordinary course of Tenant’s business, and if Landlord is unable to provide to Tenant substitute office space within the Building which is reasonably comparable to the OS Tenant Space (Landlord agreeing, in such event, to use reasonable efforts to provide such comparable substitute space to Tenant), Tenant may terminate this Lease only with respect to the OS Tenant Space 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 with respect to the OS Tenant Space only 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.

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.

          9.1.3 Tenant’s Remedy. Tenant’s termination rights and rights to abatement of Base Rent and Tenant’s Proportionate Share of Taxes — Property, 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. Notwithstanding anything to the contrary contained herein, however, if any Casualty Event is caused by any act of willful misconduct of Tenant or any Tenant Party, then Tenant shall not be entitled to terminate this Lease under Section 9.1.1.2, and there shall be no abatement of any Base Rent (or any other Rent or other amounts) due hereunder.

     9.2 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 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. If Tenant does not deliver to Landlord a certificate or other proof of renewal or coverage from an insurance carrier at least ten (10) business days prior to the expiration dates of each expiring policy, Landlord may, if Tenant has not cured such default within five (5) business days after receipt of written notice from Landlord, obtain such insurance on behalf of Tenant, and Tenant shall, within ten (10) days after Landlord’s demand therefor, pay to Landlord an amount equal to the cost of such insurance policies plus an administrative surcharge of ten percent (10%).

     9.3 Landlord’s Insurance.

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, other than Landlord’s Installations and Landlord’s OS Installations.

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. 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 twenty (20) 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 twenty (20) 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; provided however, that if the proposed Transfer is a sublease or other Transfer of only a portion of the Tenant Space and/or for a portion of the remaining Term, Landlord shall only have the right to terminate (or suspend, as the case may be) the Lease with respect to the portion of the Tenant Space for the portion of the remaining Term which Tenant proposes to sublease or Transfer. If Landlord exercises its right to terminate or suspend the Term of the Lease with respect to only a portion of the Tenant Space, then the Base Rent and Tenant’s Proportionate Share shall be reduced based pro-rata for the time period of such termination or suspension based upon the reduction in the electrical capacity available to Tenant in the remaining portion of the Tenant Space.

     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 be responsible for the performance of all Tenant’s obligations 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 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.

At any time and from time to time, within ten (10) business days after written request by Landlord, Tenant shall execute, acknowledge and deliver to Landlord a statement in writing certifying all matters 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.

     11.2 Estoppel Certificate by Landlord. At any time and from time to time, within ten (10) days after written request by Tenant, Landlord shall execute, acknowledge and deliver to Tenant a statement in writing certifying all matters reasonably requested by Tenant or any current or prospective transferee of Tenant’s, purchaser of Tenant or any current or prospective lender to Tenant or such transferee, including the nature of known defaults by Tenant under the Lease, if any. Landlord acknowledges and agrees that any statement delivered (or to be delivered) pursuant to this Article 11 may be relied upon by any current or prospective transferee and/or purchaser of Tenant, and/or any lender to Tenant or such transferee.

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, the Datacenter 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. 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, the Datacenter, 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 ten (10) business days after 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. 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. Landlord agrees to request that the holder of the Security Documents affecting the Building as of the Effective Date enter in an SNDA with Tenant. Landlord represents to Tenant that, as of the Execution Date of this Lease, the only mortgage affecting the Building is held by BANK OF AMERICA, N.A. AS SUCCESSOR TO WELLS FARGO BANK, N.A., AS TRUSTEE FOR THE REGISTERED HOLDERS OF WACHOVIA BANK COMMERCIAL MORTGAGE TRUST, COMMERCIAL MORTGAGE PASS-THROUGH CERTIFICATES, SERIES 2005-C17.

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, and damage caused by a Casualty Event, Taking or a default of Landlord 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) calendar 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 the Hold Over Percentage, as hereinafter defined, 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 “Hold Over Percentage” shall be defined as 150% for the first sixty (60) days of hold over in the Tenant Space by Tenant, or anyone claiming by, through or under Tenant 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) and 200% for any period of hold over by Tenant after the first sixty (60) days. 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.

     13.4 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. The foregoing waivers shall be in addition to, and not a limitation of, any other waivers or releases contained in this Lease.

     14.2 Indemnifications.

          14.2.1 Indemnification by Tenant.

               14.2.1.1 To the maximum extent permitted law, but subject to Sections 9.3 and 14.1, 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:

               (ii) injuries to persons or damage to property to the extent caused by 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 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.

               14.2.1.2 In the event that any Claim for which Landlord is entitled to indemnification under this Lease is brought against Landlord or any other member of the Landlord Group, Tenant, upon notice from Landlord, shall defend such action or proceeding at Tenant’s cost and expense. Tenant agrees that no settlement offer that involves the admission of liability by Landlord or obligation to make payment or pay damages 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 vacating 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 Subject to the limitations on Landlord’s liability expressly set forth in this Lease, Landlord hereby agrees to defend, indemnify and hold harmless Tenant and the Tenant Parties from and against (and to reimburse Tenant and any Tenant Parties for) all third party Claims to the extent arising from, in connection with, or in any manner relating to (or alleged to arise from, to be in connection with, or to be in any manner related to) injuries to persons or damage to property to the extent caused by the active gross negligence or willful misconduct of Landlord or any member of the Landlord Group at the Property, provided however, that the foregoing indemnification obligations contained in this Section 14.2.2 shall not include the obligation of Landlord to indemnify any Tenant Party to the extent that such claims are caused directly or indirectly, by the active or passive, joint, concurrent, or comparative negligence of any Tenant Party.

               14.2.2.1 In the event that any Claim for which Tenant is entitled to indemnification under this Lease is brought against Tenant or any other member of the Tenant Group, Landlord, upon notice from Tenant, shall defend such action or proceeding at Landlord’s cost and expense. Landlord agrees that no settlement offer that involves the admission of liability by Tenant or obligation to make payment or pay damages shall be offered or accepted by Tenant 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 or prior to Tenant vacating 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 Landlord or Tenant.

     14.3 Consequential Damages. Notwithstanding anything to the contrary (express or implied) contained herein, except with regard to Tenant’s obligations to indemnify Landlord, as expressly set forth in Section 14.2.1.1(i)(g) and (h) above, under no circumstances whatsoever shall Landlord or Tenant ever be liable under this Lease for first-party or third-party Consequential Damages.

     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 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 by Tenant, by bonding or otherwise, within thirty (30) calendar days after the later of: (i) filing of the lien, or (ii) Tenant being made aware of the lien.

     15.2 Remedies.

16. LANDLORD’S LIABILITY.

     16.1 Landlord Default; Tenant’s Remedies.

          16.1.1 Landlord Default. It shall constitute a Landlord Default if: (a) Landlord shall fail to perform or observe any of Landlord’s Lease Undertakings, and (b) such failure continues for a period of twenty (20) 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 twenty (20) days following written notice to Landlord, such failure to cure shall not be a Landlord Default if Landlord commences its cure within such twenty (20) day period and thereafter diligently prosecutes the curing thereof to completion.

          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, provided that the limitations on Landlord’s liability set forth in this Section 16.2(i) shall not apply to: (x) claims based upon claims of third parties for injuries to persons or damages to physical property to the extent based upon the negligence or willful misconduct of the Landlord Parties, or (y) any Outage Credits, Security/Access Credits, Full SAS 70 Credits, or Partial SAS Credits to which Tenant is entitled pursuant to Exhibit F;

               (ii) other than Landlord’s Liability Cap, Tenant shall have no recourse against any other assets of Landlord and in the uncollected rent and proceeds of the Building;

               (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.

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 either party 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 either party to perform will be waived, altered or modified, except by written instrument signed by such party.

     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 attorneys’ fees and costs (including all expense reimbursements, expert witness fees, litigation costs, court or arbitration tribunal costs, filing fees, exhibit fees, forensic consultant fees, litigation support costs, expert witness fees, the costs of appeals and 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 $500.00. 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.”

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. Unless otherwise expressly stated, the words “herein,” “hereof,” and “hereunder” and other words of similar import refer to this Lease as a whole and not to any particular Section, subsection, or other subpart of this Lease.

Each party agrees that any action by the other against such party shall be instituted in the State in which the Property is located.

     17.8 Incorporation; Amendment; Merger. This Lease, along with any schedules, exhibits and attachments or other documents referred to herein, all of which are hereby incorporated into this Lease by this reference, constitutes the entire and exclusive agreement between Landlord and Tenant relating to the Tenant Space and the Datacenter and each of the aforementioned documents may be altered, amended or revoked only by an instrument in writing signed by the party to be charged thereby. All prior or contemporaneous oral or written agreements, understandings and/or practices relative to the leasing or use of the Tenant Space are merged herein or revoked hereby.

     17.10 Examination of Lease; Binding on Parties. Each of the parties hereto acknowledges that it has read and reviewed this Lease and that it has had the opportunity to confer with counsel in the negotiation of this Lease. 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.

     17.11 Recordation. Neither Tenant nor any person or entity acting through, under or on behalf of Tenant shall record or cause the recordation of this Lease, but Landlord agrees to execute, acknowledge and deliver a statutory form of Notice of Lease.

     17.12 Authority. Each of Landlord and Tenant represents to the other party that the person executing this Lease on its behalf is duly authorized to execute and deliver this Lease pursuant to its respective by-laws, operating agreement, resolution or other legally sufficient authority.

	(b)		was already rightfully known to the party receiving such information (the “Receiving Party”) prior to being disclosed by or obtained from the Party (or its agents or affiliates) disclosing such information (the “Disclosing Party”) as evidenced by written records kept in the ordinary course of business of or by proof of actual use by the Receiving Party;
	(c)		has been or is hereafter rightfully received by the Receiving Party from a third person (other than the Disclosing Party) without restriction or disclosure and without breach of a duty of confidentiality to the Disclosing Party; or

Accordingly, each party agrees as follows:

	(a)		the Receiving Party will hold any and all Confidential Information it obtains in strictest confidence and will use and permit use of Confidential Information solely for the purposes of this Lease;
	(b)		the Receiving Party may disclose or provide access to its responsible employees, attorneys, auditors, affiliates, lenders, prospective lenders, investors, prospective investors and prospective purchasers of the Property who have a need to know such Confidential Information in the ordinary course of the Receiving Party’s business; provided that, in any such case, the party disclosing Confidential Information shall advise the recipient of the fact that such information is Confidential Information under this Agreement and the party’s obligations under this Article 18; and
	(c)		the Receiving Party will notify the Disclosing Party of any actual or attempted unauthorized disclosure or use of the other party’s Confidential Information promptly after it becomes aware of such attempt or use, and will cooperate with the Disclosing Party, in any manner which the Disclosing Party reasonably requests and at no cost to the Receiving Party, to protect all proprietary rights in and ownership of its Confidential Information.

     18.6 Non-Exclusive Equitable Remedy.

     Each Party acknowledges and agrees that due to the unique nature of Confidential Information there is no adequate remedy at law for any breach of its obligations hereunder and that any such breach or threatened breach may result in irreparable harm to such Party and, therefore, that upon any such breach or any threat thereof, each Party will be entitled to seek and obtain appropriate equitable and injunctive relief from a court of competent jurisdiction without the necessity of proving actual loss, in addition to whatever remedies either of them might have at law or equity.

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, any such notice or demand being hereby waived, to the extent that such waiver is allowed by Applicable Laws:

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

          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 Event of Default, to the aforesaid exercise of dominion over Tenant’s property within the Building.

Tenant agrees that any re-entry by Landlord may be pursuant to judgment obtained in unlawful 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 in good faith 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).

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.

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 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, incurred by Landlord in good faith, 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 reasonable 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. In addition to the other remedies provided in this Lease, subject to Applicable Laws, Landlord shall be entitled to a restraint by injunction of the violation or attempted or threatened violation of any of the covenants, conditions or provisions of this Lease or to a decree compelling specific performance of any such covenants, conditions or provisions.

          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 based upon a 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 or in 200 Quannapowitt Parkway shall be deemed to have satisfied Landlord’s obligation to use “reasonable efforts.” 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 (other than those which Tenant is expressly permitted to use under the Lease); or (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 the final and unappealable legal right to re-let the Tenant Space free of any claim of Tenant to occupy the Tenant Space.

          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 incurred by Landlord in good faith (including reasonable 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 payments under Section 3.5) are commercially reasonable and valid even though such methods may not state a precise mathematical formula for determining such charges.

COMMISSIONING CRITERIA

Commissioning consists of five general levels of activities summarized as follows:

Level 1 — Factory Testing

Manufacturers’ standard test reports will be reviewed prior to shipment of equipment to the site.

Level 2 — Component Verification

Individual system components are verified at the site upon delivery for compliance with the design specifications, drawings, and approved submittals or shop drawings.

Level 3 — System Construction Verification

As the components are assembled into individual systems, the construction or installation of the overall system is verified. This includes an evaluation of interconnection between components, physical arrangement, support and anchoring, and access and clearance.

Level 4 — Individual System and Major Equipment Operation Verification

Subsequent to the completion of construction and assembly of each individual system or major equipment element, it is started-up and tested for proper functional operation and performance.

Level 5 — Integrated Systems Operation Verification

The test procedures that comprise Level 5 commissioning are designed to simulate the operation of the Premises’ infrastructure during a full range of operational situations, including loss of utility services, single and multiple equipment failure, normal sequential changes to the equipment operation, and planned maintenance operations.

This effort is dependent upon the successful completion of all prior levels of commissioning. The assembly of appropriate documentation and certifications for the completion of Level Four commissioning will be a prerequisite.

Level 5 commissioning will typically be completed in four basic steps:

•		Initial planning
•		Preparation of test procedures
•		Implementation of tests

     C. SAS 70 Audit Credits.

     Landlord shall cause a SAS 70 Audit of the Datacenter be performed at least once every twelve months by a qualified independent auditor. If such audit determines that the Datacenter is not in compliance with then current SAS 70 standards (or equivalent successor standards) and either: (i) Tenant is unable to use the Tenant Space for the purposes permitted under the Lease by reason of such non-compliance for any period of time, then Tenant shall be entitled a Credit (“Full SAS 70 Credit”) equal to 100% of the Rent payable by Tenant for each day that Tenant is unable use the Datacenter by reason of such non-compliance, or (ii) if, despite such non-compliance, Tenant is able to use the Tenant Space for the purposes permitted under the Lease for a period after the date (“SAS 70 Cure Date”) which is (20) days after Landlord receives notice from such auditor of such non-compliance, then Tenant shall be entitled to a Credit (“Partial SAS 70 Credit”) equal to 10% of the Rent payable by Tenant for each day between SAS 70 Cure Date and the date that Landlord cures such non-compliance.

     D. Procedures.

     In the event that Tenant is entitled to an Outage Credit, Security/Access Credit, Full SAS 70 Credit, or Partial SAS 70 Credit, such Credit 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 a Credit accrues during the final month of the Term, Landlord will pay to Tenant the amount of such Credit within thirty (30) days following the expiration of the Term.

     E. Limits on Credits.

     The foregoing notwithstanding, (a) the total aggregate amount of Outage Credits, Security/Access Credits, Full SAS 70 Credits, and Partial SAS 70 Credits to which Tenant may become entitled in any calendar month shall not exceed Tenant’s total monthly Base Rent (at the time of the event); and (b) Tenant’s entitlement to, and accrual of, Outage Credits related to any Interruption — Electrical shall occur only from and after the point at which the aggregate duration of all Interruptions — Electrical during any rolling twelve (12) month period exceeds the Interruption — Electrical Duration Threshold.

     F. Cure Notices. Once Landlord has rectified a particular Interruption of Landlord’s Essential Services, Security/Access Incident, or SAS 70 non-compliance, Landlord shall provide notice of such rectification or cure to Tenant as soon as is reasonably practicable thereafter.

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. If Tenant exercises its termination right under this Paragraph B, then Landlord shall reimburse Tenant for the reasonable costs incurred by Tenant in moving Tenant’s Personal Property from the Tenant Space and OS Space to a new location.

     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.

4. Remedies Exclusive.

     6. MISCELLANEOUS.

          6.1 Incorporation; Amendment; Merger.

This Rider is hereby incorporated into the Lease by this reference.

          6.2 Effectiveness of Rider. This Rider shall not be binding or effective until the parties have executed and delivered an original or counterpart hereof to each other.

          6.3 Authority. Landlord and Tenant hereby represent to one another that the persons executing this Rider on behalf of Landlord and Tenant are duly authorized to execute and deliver this Rider pursuant to their respective by-laws, operating agreement, resolution or other legally sufficient authority.

Landlord and Tenant agree that the delivery of an executed copy of this Rider by facsimile or e-mail shall be legal and binding and shall have the same full force and effect as if an original executed copy of this Rider had been delivered.

          6.5 Confidentiality. Each party agrees that (i) the terms and provisions of this Rider are confidential and constitute proprietary information of the parties; and (ii) as such, the terms and provisions of this Rider are, and shall be, subject to the terms of Section 17.19 of the Lease.

          6.6 POP Room Master Lease. Without limiting the generality of the foregoing, Landlord may enter into a Master Lease, and in such event, this Rider will automatically, without consent or further action of Tenant, be deemed a sublease between the Third Party Tenant, and Tenant, as subtenant. This provision is self-operating; however, Tenant agrees to execute any documents needed to confirm such sublease, and if the Master Lease is entered into and Third Party Tenant defaults thereunder, Tenant will attorn to Landlord, as substitute sublandlord, and, provided Tenant is not in default under the Lease after the expiration of any applicable notice and cure periods, Tenant may remain in possession of the POP Tenant Space under the terms of this Rider, even if Landlord should terminate the Master Lease. Landlord shall, as a condition to causing Tenant’s rights in the POP Room to be a sublease with the Third Party Tenant, enter into a commercially reasonable form of Subordination, Nondisturbance and Attornment Agreement with Tenant with respect to this Rider and the POP Room.

     2. OS RIDER TERM. The term of this Rider, and Tenant’s obligation to pay OS Base Rent and other sums due under this Rider, shall commence on the OS Commencement Date and shall continue in effect for the OS Rider Term, unless this Rider is earlier terminated as provided herein.

          3.1 OS Base Rent. Landlord hereby acknowledges receipt of all the OS Base Rent due and payable for the entire OS Rider Term.

          3.2 Operating Expenses and Taxes.

               3.2.1 Tenant shall be obligated to pay to Landlord as Additional Rent an amount equal to Tenant’s Proportionate OS Share of Operating Expenses (Actual).

               3.2.2 Beginning with the OS Commencement Date (or as soon thereafter as reasonably possible), Landlord shall provide to Tenant a statement of the Operating Expenses (Projected) and the Taxes (Projected). Tenant shall pay each Projected Operating Expense Installment — OS and each Projected Tax Installment — OS to Landlord the first day of each month during the Rider Term. Until Tenant has received the statement of the Operating Expenses (Projected) and the Taxes (Projected) from Landlord, Tenant shall continue to pay Projected Operating Expenses Installments — OS and Projected Tax

Installment — OS to Landlord in the same amount (if any) as required for the last month of the prior calendar year. Upon Tenant’s receipt of such statement of the Operating Expenses (Projected), Tenant shall pay to Landlord, or Landlord shall pay to Tenant (whichever is appropriate), the difference between the total of the monthly amounts paid by Tenant as Projected Operating Expenses Installment — OS prior to receiving such statement and the amount payable by Tenant therefor as set forth in such statement. In addition, upon Tenant’s receipt of such statement of the Taxes (Projected), Tenant shall pay to Landlord, or Landlord shall pay to Tenant (whichever is appropriate), the difference between the total of the monthly amounts paid by Tenant as Projected Tax Installment — OS prior to receiving such statement and the amount payable by Tenant therefor as set forth in such statement.

However, if Tenant’s Proportionate OS Share of Operating Expenses (Actual) for such calendar year is less than the total of the monthly amounts of Projected Operating Expenses Installment — OS collected by Landlord from Tenant, Landlord shall pay to Tenant, within thirty (30) days following Tenant’s receipt of such statement, the amount of such excess (but such payment shall be made by Landlord by no later than the June 30^th next following the calendar year in question). If Tenant’s Proportionate OS Share of Taxes (Actual) for such calendar year exceeds the total of the monthly amounts of the Projected Tax Installments — OS collected by Landlord from Tenant, Tenant shall pay to Landlord, within thirty (30) days following Tenant’s receipt of such statement, the amount of such excess. However, if Tenant’s Proportionate OS Share of Taxes (Actual) for such calendar year is less than the total of the monthly amounts of the Projected Tax Installments — OS collected by Landlord from Tenant, Landlord shall pay to Tenant, within thirty (30) days following Tenant’s receipt of such statement, the amount of such excess (but such payment shall be made by Landlord by no later than the June 30^th next following the calendar year in question). Landlord shall have the right from time to time during each calendar year to revise the Operating Expenses (Projected) and/or Taxes (Projected) and provide Tenant with a revised statement thereof. Thereafter, Tenant shall pay Projected Operating Expenses Installments — OS and Projected Tax Installments — OS on the basis of the revised statement. If the OS Effective Date is not the first day of a calendar year, or the expiration or termination date of this Rider is not the last day of a calendar year, Tenant’s Proportionate OS Share of Operating Expenses (Actual) and Tenant’s Proportionate OS Share of Taxes (Actual) shall be prorated. The foregoing adjustment provisions shall survive the expiration or termination of the Rider Term.

               3.2.3 Notwithstanding any other provision herein to the contrary, it is agreed that if the Building is not ninety-five percent (95%) or more occupied during any calendar year an adjustment shall be made in computing the Operating Expenses (Actual) that vary with occupancy for such year so that the Operating Expenses (Actual) that vary with occupancy are computed as though the Building had been ninety-five percent (95%) occupied during such year.

               3.2.4 Notwithstanding anything to the contrary herein contained, for the purposes of computing Tenant’s Proportionate OS Share of Operating Expenses (Actual), Controllable Operating Expenses shall not increase by more than 3% per calendar year on a compounding and cumulative basis over the course of the Term of this Lease. In other words, the amount of Controllable Operating Expenses for each calendar year during the Term of this Lease which may be included in Operating Expenses (Actual) shall not exceed the Controllable Expense Cap, as hereinafter defined, for such calendar year (see Exhibit B for an example of the definition of the Controllable Expense Cap). The “Controllable Expense Cap” for 2012 shall be one hundred five (103%) percent of the amount of Controllable Operating Expenses (as the same may be adjusted pursuant to Section 3.2.3 included in Operating Expenses Actual for 2011. The “Controllable Expense Cap” for each calendar after 2012 shall be one hundred three (103%) percent of the Controllable Expense Cap for the immediately preceding calendar year (as the same may be adjusted pursuant to Section 3.2.3).

               3.2.5 Landlord agrees to keep books and records reflecting the Operating Expenses and Taxes of the Property in accordance with generally accepted accounting principles. Tenant, at its expense, shall have the right, within eight (8) months after receiving Landlord’s statement of Operating Expenses (Actual) and Taxes (Actual) for a particular year, to audit Landlord’s books and records relating to the Operating Expenses and Taxes as the case may be for such year. If conducted by Tenant, such audit shall be conducted only during regular business hours at Landlord’s office and only after Tenant gives Landlord fourteen (14) days written notice. Tenant shall deliver to Landlord a copy of the results of such audit within fifteen (15) days of its receipt by Tenant. No audit shall be conducted at any time that Tenant is in default (beyond the expiration of applicable grace, notice or cure periods) of any of terms of the Lease or this Rider. No subtenant shall have any right to conduct an audit and no assignee shall conduct an audit for any period during which such assignee was not in possession of the OS Tenant Space. Such audit must be conducted by an independent nationally recognized accounting firm that is not being compensated by Tenant on a contingency fee basis. All information obtained through the Tenant’s audit with respect to financial matters (including, without limitation, costs, expenses, income) and any other matters pertaining to the Landlord and/or the Property as well as any compromise, settlement, or adjustment reached between Landlord and Tenant relative to the results of the audit shall be held in strict confidence by the Tenant and its officers, agents, and employees; and Tenant shall cause its auditor and any of its officers, agents, and employees to be similarly bound. As a condition precedent to Tenant’s exercise of its right to audit, Tenant must deliver to Landlord a signed covenant from the auditor in a form reasonably satisfactory to Landlord acknowledging that all of the results of such audit as well as any compromise, settlement, or adjustment reached between Landlord and Tenant shall be held in strict confidence and shall not be revealed in any manner to any person except upon the prior written consent of Landlord, which consent may be withheld in Landlord’s sole discretion, or if required pursuant to any litigation between Landlord and Tenant materially related to the facts disclosed by such audit, or if required by Applicable Law. Tenant understands and agrees that this provision is of material importance to Landlord and that any violation of the terms of this provision shall result in immediate and irreparable harm to Landlord. Landlord shall have all rights allowed by law or equity if Tenant, its officers, agents, or employees and/or the auditor violate the terms of this provision, including, without limitation, the right to terminate this Rider or the right to terminate Tenant’s right to audit in the future pursuant to this paragraph. Tenant shall indemnify, defend upon request, and hold Landlord harmless from and against all costs, damages, claims, liabilities, expenses, losses, court costs, and attorneys’ fees suffered by or claimed against Landlord, based in whole or in part upon the breach of this paragraph by Tenant and/or its auditor, and shall cause its auditor to be similarly bound. If within such eight (8) month period Tenant does not give Landlord written notice stating in reasonable detail any objection to the statement of Operating Expenses (Actual) and/or Taxes (Actual), Tenant shall be deemed to have approved such statement in all respects.

          3.3 OS Base Rent and Charges.
