 NOW, THEREFORE, the

designated as a holiday under Federal or applicable State statute or regulation, on which Bank is open for all or substantially all of its domestic and international business (including dealings in foreign exchange) in San Jose, California, and, in
respect of notices and determinations relating to the Daily Adjusting LIBOR Rate, also a day on which dealings in dollar deposits are also carried on in the London interbank market and on which banks are open for business in London, England.”

 “‘Consolidated Cash’ means all unrestricted cash and cash equivalents (including, without limitation, unrestricted cash and
cash equivalents maintained in territories other than the United States of America).” 
 “‘Daily Adjusting LIBOR Rate’
means, for any day, a per annum interest rate which is equal to the quotient of the following:

annum rate of interest determined on the basis of the rate for deposits in United States Dollars for a period equal to one (1) month appearing on Page BBAM of the Bloomberg Financial Markets Information Service as of 8:00 a.m. (California time)
(or as soon 
  

 1 

 
thereafter as practical) on such day, or if such day is not a Business Day, on the immediately preceding Business Day. In the event that such rate does not
appear on Page BBAM of the Bloomberg Financial Markets Information Service (or otherwise on such Service) on any day, the ‘Daily Adjusting LIBOR Rate’ for such day shall be determined by reference to such other publicly available service
for displaying eurodollar rates as may be reasonably selected by Bank, or, in the absence of such other service, the ‘Daily Adjusting LIBOR Rate’ for such day shall, instead, be determined based upon the average of the rates at which Bank
is offered dollar deposits at or about 8:00 am. (California time) (or as soon thereafter as practical), on such day, or if such day is not a Business Day, on the immediately preceding Business Day, in the interbank eurodollar market in an amount
comparable to the applicable principal amount of Indebtedness hereunder and for a period of one (1) month; 
 divided by

 (b) 1.00 minus the maximum rate (expressed as a decimal) on such day at which Bank is required to maintain reserves on
‘Euro-currency Liabilities’ as defined in and pursuant to Regulation D of the Board of Governors of the Federal Reserve System or, if such regulation or definition is modified, and as long as Bank is required to maintain reserves against a
category of liabilities which includes eurodollar deposits or includes a category of assets which includes eurodollar loans, the rate at which such reserves are required to be maintained on such category.” 
 “‘Eligible Foreign Account’ means an Account which meets all of the requirements to be an Eligible Account except with respect to which the
account debtor does not have its principal place of business in the United States and that is (i) supported by one or more letters of credit in an amount and of a tenor, and issued by a financial institution, acceptable to Bank and approved by
Bank in writing, (ii) insured by the Export Import Bank of the United States, (iii) an Account owed by an Approved Foreign Account Debtor or (iv) approved by Bank on a case-by-case basis. All Eligible Foreign Accounts must be
calculated in U.S. Dollars.” 
 “‘Material Foreign Subsidiary’ means any Subsidiary (i) that is not a registered
organization which is organized under the laws of one of the states comprising the United States (e.g. corporation, limited partnership, registered limited liability partnership or limited liability company) and (ii) whose assets comprise more
than ten percent (10%) of the total consolidated assets of Borrower and its Subsidiaries.” 
 “‘Non-Formula Amount’
means, as of any date of determination, the lesser of (i) $7,500,000.00 and (ii) the amount of Borrower’s Cash held in depository, investment and operating accounts with Bank.” 
 “‘Prime Rate’ means the per annum interest rate established by Bank as its prime rate for its borrowers, as such rate may vary from time to
time, which rate is not necessarily the lowest rate on loans made by Bank at any such time.” 
 “‘Prime Referenced Rate’
means, for any day, a per annum interest rate which is equal to the Prime Rate in effect on such day, but in no event and at no time shall the Prime Referenced Rate be less than the sum of the Daily Adjusting LIBOR Rate for such day plus two and
one-half percent (2.50%) per annum. If, at any time, Bank determines that it is unable to determine or ascertain the Daily Adjusting LIBOR Rate for any day, the Prime Referenced Rate for each such day shall be the Prime Rate in effect at such
time, but not less than two and one-half percent (2.50%) per annum.” 
 “‘Revolving Maturity Date’ means
April 30, 2011.” 
 “‘Second Amendment Date’ means April 29, 2009.”

Agreement, as amended hereby, shall be and remain in full force and effect in accordance with its respective terms and hereby is ratified and confirmed in all respects. Except as expressly set forth herein, the execution, delivery, and performance

including any lobby area, the loading dock, and any other areas devoted to the public, such as corridors, fire vestibules, restrooms, janitor closets and

 ARTICLE II 
 TERM 
 2.1 Except as otherwise set forth herein, all of the provisions of this Lease shall be
in full force and effect from and after the Effective Date. The term of this Lease (hereinafter referred to as the “Lease Term”) shall commence on the Lease Commencement Date, as determined pursuant to Section 2.2 below,
and continue for a period of fifteen (15) years thereafter unless such Lease Term shall be extended, renewed or terminated earlier in accordance with the provisions hereof. The term “Lease Term” shall include any
properly exercised renewals and extensions of the term of this Lease. 
 2.2 (a) The “Lease Commencement Date”
shall be the earlier of (i) the date that is one hundred eighty (180) days after the Effective Date (the “Anticipated Lease Commencement Date”) and (ii) the date on which Tenant commences the conduct of its
business upon any portion of the Premises, but only with respect to such portion. Landlord represents that as of the Effective Date, the following items have been completed, obtained and/or are true, as applicable, and Landlord warrants and
covenants that the same will be completed, in effect and/or true, as applicable, as of the Lease Commencement Date: (I) Landlord’s Work (as hereinafter defined) has been substantially completed in accordance with Section 9.1 below;
(II) all mechanical and electrical systems for Pod 8b, and all components thereof, including, without limitation, computer room air conditioning units (“CRACs”) and other components of the HVAC system, uninterruptible power
systems (“UPSs”), EPO kiosks, and back-up diesel engine generators (“Engine Generators”), and the Building Security Systems (as hereinafter defined) and Building Management System (as
hereinafter defined), are in good working order; (III) data center level 4 testing and level 5 commissioning have been completed with respect to all mechanical and electrical systems for Pod 8b as certified by CCG Facilities Integration
Incorporated, the Building engineer; and (IV) a certificate of occupancy and any other required occupancy and/or use permits have been issued by Loudoun County for the Building, including Pod 8b. For avoidance of doubt, except as otherwise expressly
provided in Section 2.4 below, the Early Access (as hereinafter defined), the Electrical and Mechanical Systems Testing (as hereinafter defined) and Tenant’s performance of Tenant’s Work (as hereinafter defined) shall not constitute
the conduct of Tenant’s business upon any portion of the Premises. 
 (b) [*****] Notwithstanding the foregoing, 2.275 megawatts
of Critical Load Power will be available to the Premises as of the Lease Commencement Date, and Tenant may use more than the applicable Phase Load Limit, up to the Maximum Load Limit (as hereinafter defined), at any time during the Lease Term,
subject to and in accordance with the terms and provisions of this Section 2.2(b). 
 (c) Notwithstanding anything to the
contrary contained herein, Landlord and Tenant acknowledge that, as of the Effective Date, Landlord has not installed the Building-standard number of power distribution units (“PDUs”) in Pod 8b. Landlord covenants that, after
receipt and approval of Tenant’s plans and specifications for Tenant’s Installations (as hereinafter defined) in accordance with Article IX below (the “Installations Plans and 

  

 3. 

			
		  	CONFIDENTIAL MATERIAL HAS BEEN OMITTED AND
		  	FILED SEPARATELY WITH THE SECURITIES AND
		  	EXCHANGE COMMISSION. BOXES AND ASTERIXES
		  	DENOTE SUCH OMISSION

  

 
Specifications”), and after consulting with and reasonably considering suggestions by Tenant, Landlord shall install the Building-standard
number of PDUs in Pod 8b as set forth in this subsection (c). In connection therewith, Tenant shall use commercially-reasonable, diligent efforts to deliver the Installations Plans and Specifications to Landlord within thirty (30) days after
the Effective Date. Landlord agrees to review and either approve or disapprove of the Installation Plans and Specifications within ten (10) days after its receipt thereof from Tenant and Landlord further agrees to not unreasonably withhold or
condition its approval of the Installation Plans and Specifications. Landlord shall use commercially-reasonable, diligent efforts to install the Building-standard number of PDUs in Pod 8b within forty-five (45) days after Landlord approves the
Installation Plans and Specifications. Notwithstanding the foregoing, provided that Landlord approves the Installations Plans and Specifications by May 15, 2009 in accordance with this Section 2.2(c), Landlord shall, subject to any delays
caused by Tenant, install the Building-standard number of PDUs in Pod 8b by no later than the Anticipated Lease Commencement Date. As used herein, “Building-standard number of PDUs” shall mean ten (10) 300 kVA PDUs.

 (d) Notwithstanding anything to the contrary contained herein, in the event: (i) Landlord does not install the
Building-standard number of PDUs in Pod 8b as set forth in subsection (c) above; and (ii) DFTS (as hereinafter defined) or another affiliate of Landlord, is engaged by Tenant to perform Tenant’s Work but fails to complete
Tenant’s Work, all on or prior to the Anticipated Lease Commencement Date, then the Lease Commencement Date shall be delayed until the date on which both such conditions are satisfied or completed as provided herein. Notwithstanding the
foregoing, if Landlord shall be delayed in satisfying the conditions set forth in clause (i) and/or clause (ii) above as a result of delays caused by Tenant, then, for purposes of determining when any such condition is satisfied, such
condition shall be deemed satisfied on the date such condition would have been satisfied absent any such Tenant-caused delay. Within ten (10) days after the occurrence of a Tenant-caused delay, Landlord shall notify Tenant in writing of such
Tenant-caused delay. If Landlord fails to so notify Tenant within said ten (10) day period and such failure to notify continues for twenty (20) days thereafter, then Landlord shall be deemed to have waived and excused any such
Tenant-caused delay. 
 (e) Promptly after the Lease Commencement Date and the commencement of each subsequent Phase are ascertained,
Landlord and Tenant shall execute a written declaration setting forth, as applicable, the Lease Commencement Date, the commencement date of each subsequent Phase (subject to the provisions of Section 2.2(b) above), and the date upon which the
Lease Term and the applicable Phase will expire. The form of such declaration is attached hereto as Exhibit C and made a part hereof. 
 2.3 For purposes of this Lease, the term “Lease Year” shall mean either (a) if the Lease Commencement Date shall not occur on the first day of a calendar month, each period of twelve (12) consecutive
calendar months commencing on the first day of the month immediately following the month in which the Lease Commencement Date occurs, and on each anniversary of such date, provided that the first Lease Year shall also include the period from the
Lease Commencement Date to the first day of the month immediately following the Lease Commencement Date; or (b) if the Lease Commencement Date shall occur on the first day of a calendar month, each period of twelve (12) consecutive
calendar months commencing on the Lease Commencement Date and on each anniversary of such date; whichever is applicable.

 2.4 Landlord shall permit Tenant to enter Pod 8b starting on the Effective Date (the
“Early Access”), in order to commence installation of racks, infrastructure, furniture and other equipment in the Premises (“Tenant’s Installations”) and to perform the remainder of Tenant’s
Work (as hereinafter defined), provided that, prior to commencing any such work in the Premises, Tenant shall comply in all respects with the requirements of Article IX below. In performing Tenant’s Work during Tenant’s Early Access,
Tenant shall be permitted to use [*****] and normal, non-Critical Load Power in the Premises, at its expense, for installation and testing. Except as otherwise expressly provided herein below, [*****] Tenant will be deemed to have commenced the
conduct of its business for purposes of subpart (ii) of the first sentence of Section 2.2(a) hereof, provided, that Landlord shall not be required to give Tenant more than one (1) such notice and opportunity to cure during Early
Access. All terms and conditions of this Lease, as executed, shall apply to Tenant’s Early Access[*****]. Notwithstanding anything to the contrary contained herein, Landlord acknowledges and agrees that: (a) Tenant, at Tenant’s sole
cost and expense pursuant to a separate agreement between Tenant and DFTS (as hereinafter defined), shall be permitted during the Early Access to perform certain testing reasonably agreed to by Landlord, Tenant and DFTS, with respect to the
electrical and mechanical systems for the Building and Pod 8b (the “Electrical and Mechanical Systems Testing”), and (b) the use of Critical Load Power, including the use of [*****], in Pod 8b for any period of time in
connection with such Electrical and Mechanical Systems Testing shall not be considered the conduct of Tenant’s business for purposes of subpart (ii) of the first sentence of Section 2.2(a) above. 
 ARTICLE III 
 BASE RENT

 3.1 Commencing on the Lease Commencement Date, Tenant shall pay to Landlord as monthly base rent (“Base
Rent”), net of all Operating Expenses (which term is defined in Section 4.2 below), without set off, deduction (unless otherwise expressly agreed to herein) or demand, an amount equal to [*****]. The monthly Base Rent payable
hereunder shall be due and payable in advance on the first day of each month. Payment of monthly Base Rent for any fractional calendar month shall be prorated. 
 3.2 The Base Rent Rate shall be escalated on the first day of the second Lease Year, and each anniversary of such date thereafter during the Lease Term (each, an “Escalation Date”) by
[*****]. 
 “CPI” means the Consumer Price Index for all Urban Consumers, U.S., City Average (1982-84 = 100) All
Items Index, published by the Bureau of Labor Statistics, United States Department of Labor. If the CPI ceases to be compiled and published at any time during the Lease Term, but a comparable successor index is compiled and published by the Bureau
of Labor Statistics, United States Department of Labor, the adjustments to Base Rent and any other adjustments provided for in this Lease which are based on the CPI will be computed according to such successor index, with appropriate adjustments in
the index to reflect any differences in the 

  

 5. 

			
		  	CONFIDENTIAL MATERIAL HAS BEEN OMITTED AND
		  	FILED SEPARATELY WITH THE SECURITIES AND
		  	EXCHANGE COMMISSION. BOXES AND ASTERIXES
		  	DENOTE SUCH OMISSION

  

 
method of computation from the CPI. If, at any time during the Lease Term, neither the CPI nor a comparable successor index is compiled and published by the
Bureau of Labor Statistics, the index for “all items” compiled and published by any other branch or department of the federal government will be used as a basis for calculation of the CPI-related adjustments to Base Rent and other amounts
provided for in this Agreement, and if no such index is compiled and published by any branch or department of the federal government, the statistics reflecting cost of living increases or decreases, as applicable, as compiled by any institution or
organization or individual generally recognized as an authority by financial and insurance institutions will be used. 
 3.3
Commencing on the Storage Space Commencement Date, in addition to the monthly Base Rent set forth in Section 3.1 above, Tenant shall pay to Landlord (i) monthly base rent in the amount of [*****] (the “Office
Rent”) and (ii) [*****] for the Storage Space (the “Storage Rent”). The Office Rent and Storage Rent shall be due and payable in advance of the first day of each month. The Office Rent and Storage Rent shall
be increased each Lease Year as and when Base Rent is increased pursuant to Section 3.2 above. Payments of Office Rent and/or Storage Rent for any fractional calendar month shall be prorated. 
 3.4 All rent shall be paid to Landlord in legal tender of the United States at the address to which notices to Landlord are to be given or to such
other address as Landlord may designate from time to time by written notice to Tenant. If Landlord shall at any time accept rent after it shall come due and payable, such acceptance shall not excuse a delay upon subsequent occasions, or constitute
or be construed as a waiver of any of Landlord’s rights hereunder. 
 ARTICLE IV 
 ADDITIONAL RENT 
 4.1 From and
after the Lease Commencement Date, Tenant shall pay its Pro Rata Share of Operating Expenses (as defined below) incurred each year in the operation of the Property, including the Management Fees (as defined below), in the manner set forth herein
below. Tenant’s “Pro Rata Share” shall mean six and twenty-five hundredths percent (6.25%). Commencing on the Lease Commencement Date and continuing throughout the Lease Term, Tenant shall pay its Pro Rata Share of all
Operating Expenses[*****]. 
 4.2 (a) “Operating Expenses” shall, subject to the exclusions set forth below,
mean and include those direct reasonable expenses actually incurred (directly or indirectly) by Landlord in operating and maintaining the Property (or any portion thereof), calculated in accordance with generally accepted accounting principles and
real property management practices, both consistently applied, including the following: [*****]. Notwithstanding the foregoing to the contrary, Operating Expenses shall not include: (i) the cost of any capital improvement to the Property other
than those included in clause (6) above; (ii) expenses Landlord incurs in connection with leasing or procuring tenants or renovating space for new or existing tenants, including brokerage commissions, legal fees, lease concessions, rental
abatements and construction allowances; (iii) costs and fees including, without limitation, legal fees, incurred in disputes with Tenant or other tenants at the Building, in connection with

enforcing leases at the Building and in connection with violations of laws by Landlord with respect to the Property; (iv) interest or principal payments
on any mortgages or, subject to clause (6) above, other indebtedness of Landlord; (v) ground lease payments; (vi) the cost of repairs or other work to the extent Landlord is reimbursed by insurance (or would have been reimbursed had
Landlord maintained the insurance coverages required in Article 12 below) or condemnation proceeds; (vii) costs incurred in connection with the sale, financing or refinancing of the Building; (viii) organizational expenses associated with
the creation and/or operation of the ownership entity which constitutes Landlord; (ix) Landlord’s administrative costs, except as they relate to the management and operation of the Property; (x) advertising, promotion, charitable and
tenant relations expenses; (xi) any amount for which Landlord receives payment directly by a tenant or non-tenant other than as an Operating Expense; (xii) the cost of correcting defects in the original construction or any renovation of
the Building; (xiii) the cost of maintaining, repairing and/or replacing the foundation, roof, exterior walls and/or any other structural element of the Building; (xiv) depreciation (except to the extent permitted in clause 6 above);
(xv) costs associated with the cleanup or removal of Hazardous Materials that are in existence as of the Effective Date in violation of applicable laws; and (xvi) costs for which Landlord is compensated by warranties. 
 (b) “Taxes” shall mean and include (i) all taxes on real property and personal property, ad valorem taxes,
surcharges, general and special assessments and impositions, general and special, ordinary and extraordinary, foreseen or unforeseen, of any kind levied or, imposed upon Landlord, the Building or the Land, or assessed against the Property or any
machinery, equipment, fixtures or other personal property of Landlord thereon or therein, or in connection with the use thereof (including any transit, personal property, sales, rental, use, gross receipts and occupancy tax and other similar
charges); (ii) any other present or future taxes or governmental charges which are imposed upon Landlord or assessed against the Building or the Land, including, but not limited to, any tax levied on or measured by the rents payable by Tenant
which is in the nature of, or in substitution for, real property taxes; (iii) any assessments against the Building or the Land, or against Landlord with respect to the Building or the Land, by the Ashburn Corporate Center Owners Association or
any other association now or hereafter established to administer, oversee or enforce common covenants or other rules and regulations to which the Building, Land or common areas are subject or to operate, maintain, repair or replace common or public
areas or facilities thereof; and (iv) all taxes which are imposed upon Landlord, and which are assessed against the value of any improvements to the Premises made by Tenant or any machinery, equipment, fixtures or other personal property of
Tenant used therein. Taxes shall not include any income taxes, excess profits taxes, excise taxes, franchise taxes, estate taxes, inheritance taxes, succession taxes, grantor’s taxes, recordation taxes, and transfer taxes, except to the extent
such taxes fall within clause (ii) above, and shall not include any interest or penalties for late payment of taxes. If Landlord contests Taxes for any calendar year(s) contained within the Lease Term and such contest results in a decrease in
Taxes for such calendar year(s), then Landlord shall credit against the monthly installments of Base Rent next coming due Tenant’s proportionate share of such refund, but only up to an amount equal to the payment made by Tenant for such
contested calendar year(s) on account of Taxes. If Landlord contests the Taxes for any calendar year(s) and such contest results in an increase in Taxes for such calendar year(s), Landlord shall have the right to bill Tenant for prior underpayments
of Taxes thereby resulting. Landlord’s and Tenant’s obligations under this Section 4.2(b) shall survive the expiration or earlier termination of the Lease Term.

 (c) Notwithstanding anything to the contrary contained herein, Landlord shall use commercially
reasonable efforts to minimize Operating Expenses without compromising the integrity of the Building, the Premises or the services Landlord is required to provide under the Lease. Furthermore, Landlord shall pay, promptly when due, all Taxes
relating to the Property. 
 4.3 Tenant shall pay to Landlord, as Additional Rent for the Premises, Tenant’s Pro Rata Share of
Operating Expenses incurred by Landlord in the operation of the Building during any calendar year falling entirely or partly within the Lease Term, but Tenant’s obligation to pay Operating Expenses for any calendar year during the Lease Term
shall be apportioned so that Tenant shall pay only that portion of Tenant’s Pro Rata Share of Operating Expenses for such year as fall within the Lease Term. This provision shall survive the expiration or earlier termination of this Lease.

 4.4 In the event the average occupancy rate for the entire Building shall be less than one hundred percent (100%) or if any
tenant is paying separately for electricity or other utilities or services furnished to its premises, then, for purposes of calculating the additional rent payable by Tenant pursuant to this Article IV for each calendar year, the Operating
Expenses for such calendar year that fluctuate depending on the level of occupancy of the Building shall be increased by the amount of additional costs and expenses that Landlord reasonably estimates would have been incurred if the average occupancy
rate for the entire Building had been one hundred percent (100%) and as if no tenants had separately paid for electricity or other utilities and services for such calendar year. It is the intent of this provision to permit Landlord to recover
Operating Expenses attributable to occupied space in the Building only, even though the aggregate of such expenses shall have been reduced as a result of vacancies in the Building. This Section 4.4 shall not be construed to permit Landlord to,
and Landlord shall not, recover from Tenant additional rent on account of Operating Expenses for any calendar year which, when added to the total amount of additional rent payable by all tenants of the Building on account of Operating Expenses for
such year, will exceed the actual Operating Expenses incurred by Landlord for such year. 
 4.5 Commencing on the Lease Commencement
Date and on the first day of each month thereafter, Tenant shall make estimated monthly payments to Landlord on account of the Operating Expenses that are expected to be incurred during each calendar year falling entirely or partially within the
Lease Term. The amount of such monthly payments shall be determined as follows: commencing with the Lease Commencement Date and at the beginning of each calendar year thereafter, Landlord shall submit to Tenant a statement setting forth
Landlord’s reasonable estimate of the Operating Expenses that are expected to be incurred during such calendar year and Tenant’s Pro Rata Share thereof (as determined in accordance with Section 4.1 hereof). Except with respect to
charges for heat rejection HVAC, which shall be paid by Tenant pursuant to Section 13.4 below, Tenant shall pay to Landlord on the first day of each month following receipt of such statement during such calendar year an amount equal to
Tenant’s Pro Rata Share of the anticipated Operating Expenses multiplied by a fraction, the numerator of which is one (1) and the denominator of which is twelve (12). Except with respect to estimated charges for heat

rejection HVAC, which shall be reconciled in accordance with Section 13.4 below, within approximately ninety (90) days, but not later than one
hundred fifty (150) days, after the expiration of each calendar year, Landlord shall submit to Tenant a statement (the “Reconciliation Statement”), showing (i) the Operating Expenses actually incurred during the
preceding calendar year and Tenant’s Pro Rata Share thereof, and (ii) the aggregate amount of the estimated payments made by Tenant on account thereof. If the aggregate amount of such estimated payments exceeds Tenant’s actual
liability for such Operating Expenses, then Landlord shall credit the net overpayment against the next monthly installment(s) of Additional Rent coming due under this Lease (except that any such overpayment during the last calendar year falling
wholly or partly within the Lease Term shall be promptly refunded to Tenant by Landlord). If Tenant’s actual liability for such Operating Expenses exceeds the estimated payments made by Tenant on account thereof, then Tenant shall pay to
Landlord the total amount of such deficiency within thirty (30) days after its receipt of the applicable Reconciliation Statement from Landlord. The provisions of this paragraph shall survive the expiration or earlier termination of this Lease.
[*****] 
 4.6 Provided no Event of Default exists hereunder, Tenant or an independent certified public accountant (on behalf of
Tenant) reasonably approved by Landlord, shall have the right, during regular business hours, at the metropolitan Washington, D.C. area management office for the Building, and after giving at least fifteen (15) days’ advance written notice
to Landlord, to commence to have Landlord’s books and records related to Operating Expenses for the immediately preceding calendar year reviewed (and if so commenced, to diligently pursue such review to completion), provided that such review
shall be concluded not later than nine (9) months following the date of Tenant’s receipt of the Reconciliation Statement for the year to which such review relates, so long as Landlord’s books and records remain reasonably available
for review by Tenant and/or Tenant’s accountant. In connection therewith, Landlord shall maintain its books and records in a commercially reasonable condition, capable of being audited by Tenant and/or its accountant. If Landlord disagrees with
the results of Tenant’s review and audit, then Landlord and Tenant’s auditor shall together select a neutral auditor of similar qualifications to conduct a review of such books and records (the fees of such neutral auditor to be shared
equally by Landlord and Tenant), and the determination of Operating Expenses reached by such neutral auditor shall be final and conclusive. Notwithstanding anything to the contrary contained herein, in the event Landlord does not contest
Tenant’s review and audit within forty-five (45) days after receipt thereof, then Landlord shall be deemed to have approved such review and audit. If the amounts paid by Tenant to Landlord on account of Operating Expenses (a) exceed
the amounts to which Landlord is entitled hereunder, then Landlord shall credit the amount of such excess toward the next monthly payment(s) of Additional Rent due hereunder, or (b) are less than the amounts to which Landlord is entitled
hereunder, then Tenant shall pay such deficiency as Additional Rent within thirty (30) days after final determination of said Operating Expenses and receipt of written request. Excluding the fees of any neutral auditor selected by the parties
hereto as aforesaid, which shall be shared equally by Landlord and Tenant, all costs and expenses of any such review by Tenant and/or Tenant’s accountant shall be paid by Tenant; provided, however, that if the amount of Operating Expenses used
in such Reconciliation Statement to calculate Tenant’s Proportionate Share thereof was overstated by Landlord by more than five percent (5%), Landlord shall, within thirty (30) days after receipt of written request from Tenant, accompanied

Landlord, reimburse Tenant for the commercially reasonable, out of pocket hourly or flat fee costs and expenses paid by Tenant in connection with
Tenant’s review. Any and all information obtained through any such review (including without limitation, any matters pertaining to Landlord, its managing agent or the Building), and any compromise, settlement or adjustment that may be proposed
or reached between Landlord and Tenant as a result of such review, shall be held in strict confidence, and neither Tenant nor any of Tenant’s Agents shall disclose any such information to any person or entity other than a Permitted Recipient. A
“Permitted Recipient” shall be the officers, directors, partners and employees of Tenant, Tenant’s certified public accountants who have responsibilities related to Operating Expenses, Tenant’s attorneys involved
with the Lease or such review, any employees of Tenant’s auditor involved with such review, or any person or entity to whom disclosure is required by applicable judicial or governmental authority. Prior to disclosing any such information to any
Permitted Recipient (including its auditor), Tenant shall instruct such Permitted Recipient to abide by this confidentiality provision. Notwithstanding anything herein to the contrary, if Tenant does not notify Landlord in writing of any objection
to an annual Operating Expenses Reconciliation Statement within one hundred fifty (150) days after receipt thereof, then Tenant shall be deemed to have waived any such objection and shall have no right to review Landlord’s books and
records related to Operating Expenses that are the subject of such Reconciliation Statement [*****]. 
 ARTICLE V 
 SECURITY 
 5.1 Landlord shall
provide the following security services and operate and maintain, in a manner consistent with a first-class data center, the following systems with respect to the Building and the Premises, the cost of which shall be included in Operating Expenses:
(i) administration of Building perimeter security including, without limitation, the Common Areas, (ii) monitoring and administration of the Building’s access card system, (iii) monitoring and oversight of loading dock security
and the parking lot located on the Land (the “Parking Lot”), (iv) monitoring and operation of security cameras throughout the Building, and (v) monitoring of the routes of ingress to, and egress from, the Premises
and the Building (the “Building Security Systems”). 
 5.2 Tenant shall have the right to, subject to
Article IX hereof, install, manage and/or maintain, at its sole cost and expense, security services and systems to protect the Premises and vault environments including, without limitation, a secondary security perimeter within the Premises and
electronic “key card” security system and/or biometric access system, in addition to the standard Building and Property security services provided by Landlord. Tenant agrees that such security systems shall not (i) limit
Landlord’s ability to access the space in the event of an emergency or to perform routine maintenance, subject to Section 11.1 hereof, or (ii) materially, adversely affect any area outside of the Premises. Tenant shall, upon ten
(10) days’ advance written notice to Landlord, have the right to obtain, at no additional cost to Tenant, monthly reports from Landlord regarding entry data and card access for: (a) each person on the Tenant Access List (as
hereinafter defined) that enters the Building and (b) each person that enters the Premises. Tenant shall, further, have the right to request entry data, review video and card

access for the Premises, the Building and the Parking Lot, as situations dictate to resolve its own reasonable security concerns or support any necessary
personnel inquires, and Landlord or the Management Company (hereinafter defined in Section 13.5 below) shall use commercially reasonable efforts to furnish all such records, all subject to availability, no more than forty-eight (48) hours
after such request by Tenant. 
 5.3 Notwithstanding anything to the contrary contained herein, if (i) any breach of security in
the Premises shall occur, (ii) any Service Interruption (as hereinafter defined), or (iii) any other event adversely impacting the operation of the Premises occurs, Tenant shall immediately provide notice to Landlord via (a) email to
[*****] (twenty-four (24) hours per day, seven (7) days per week and three hundred sixty-five (365) days per year) and (b) telephone call to Landlord’s Emergency/Security Response Center in Ashburn, Virginia at [*****]
(twenty-four (24) hours per day, seven (7) days per week and three hundred sixty-five (365) days per year), and/or to such other email address and/or phone number as Landlord shall from time to time notify Tenant in writing
(“Landlord’s Emergency Contacts”). 
 5.4 Notwithstanding anything to the contrary contained herein, if
(i) any breach of security in the Building and/or the Premises shall occur, (ii) any Service Interruption (as hereinafter defined) and/or reductions in levels of redundancy as provided in Section 13.2 below shall occur, or
(iii) any other event adversely impacting the operation of the Premises and/or the Building occurs, Landlord shall immediately provide notice to Tenant via (a) email to [*****] (twenty-four (24) hours per day, seven (7) days per
week and three hundred sixty-five (365) days per year) and (b) telephone call to [*****] (twenty-four (24) hours per day, seven (7) days per week and three hundred sixty-five (365) days per year), and/or to such other email
address and/or phone number as Tenant shall from time to time notify Landlord in writing (“Tenant’s Emergency Contacts”). 
 5.5 Tenant shall provide to Landlord an access list (as updated and/or modified from time to time by Tenant, the “Tenant Access List”) designating employees of Tenant and Permitted
Licensees (defined in Section 7.6 below) that are permitted to enter the Premises. Each Tenant employee/Permitted Licensee designated by Tenant on the Tenant Access List shall receive a permanent access badge (an “Access
Badge”). [*****] Tenant shall be solely responsible for updating the Tenant Access List and providing any changes to Landlord. In the event that any Tenant employee or Permitted Licensee is removed from the Tenant Access List by Tenant
or no longer requires access to the Premises for any reason, Tenant shall return such Tenant employee/Permitted Licensee’s Access Badge to Landlord promptly. Landlord agrees and acknowledges that: (a) the contents of the Tenant Access List
and/or the identities of those parties visiting the Premises shall remain strictly confidential and shall not be disclosed to any other party, other than the Management Company, without the prior written consent of Tenant, and (b) Landlord
shall destroy, and not re-use, any and all Access Badges returned by Tenant to Landlord as aforesaid. If any person seeking to gain access to the Premises is not on the Tenant Access List, then such person shall be refused access to the Premises;
provided, however, that, so long as an employee or representative of Tenant has escort authorization as specifically indicated on the Tenant Access List, such employee and/or representative may escort any visitor, including, without limitation, any
vendor, supplier, partner, customer or prospective customer of Tenant, that is not on the Tenant Access List to and/or within the Premises. Without limiting the

foregoing, in no event shall Landlord permit any representative or employee of Tenant that does not have escort authorization to escort any person that is
not on the Tenant Access List to and/or within the Premises. Notwithstanding anything to the contrary contained herein, Landlord shall have the right, at any time, to require the immediate removal of any employee, agent, representative, and/or
contractor of Tenant, including, but not limited to, persons included on the Tenant Access List, from: (i) the Building or the Land for disruptive behavior or safety concerns occurring on the Property outside of the Premises or (ii) the
Premises for material interference with Landlord’s performance of its obligations within the Premises, as determined in the sole but reasonable discretion of Landlord. [*****] Landlord will provide a security orientation for its non-employee,
third-party contractors, consultants, technicians and other personnel (excluding Tenant or any of Tenant’s employees, agents or invitees) that will have access to the Premises. [*****] 
 ARTICLE VI 
 USE OF PREMISES 
 6.1 Tenant shall use and occupy the Premises solely for data center, computing, hosting and managed services purposes (including Permitted
Interconnections (as hereinafter defined)) and uses accessory thereto, including, without limitation, general office, storage, assembly and repair (“Permitted Uses”), and for no other use or purpose. Tenant shall not use or
occupy the Premises for any unlawful purpose, or in any manner that will violate the certificate of occupancy for the Premises or the Building or that will constitute waste, nuisance or unreasonable annoyance to Landlord or any other tenant or user
of the Building, or in any manner (other than the Permitted Uses) that will increase the number of parking spaces required for the Building as required by law. Tenant’s use of the Premises shall comply with all present and future laws
(including, without limitation, the Americans with Disabilities Act (the “ADA”) and the regulations promulgated thereunder, as the same may be amended from time to time), ordinances (including without limitation, zoning
ordinances and land use requirements), regulations, orders and recommendations (including, without limitation, those made by any public or private agency having authority over insurance rates) (collectively, “Laws”)
concerning the use, occupancy and condition of the Premises and all of Tenant’s machinery, equipment, furnishings, fixtures and improvements therein, all of which shall be complied with in a timely manner at Tenant’s sole expense.
Notwithstanding the foregoing, Landlord at its expense (subject to reimbursement pursuant to Article IV above, if and to the extent permitted thereby) shall comply with Laws (including, without limitation, the ADA and Environmental Laws (hereinafter
defined)) to the extent the same apply directly to the Building Structure and Systems (as hereinafter defined in Section 8.2), Common Areas of the Property as a whole, and any other portions of the Building located outside of tenant premises,
including, without limitation, telephone rooms, mechanical and electrical rooms and closets; provided, however, that to the extent any non-compliance is a result of Tenant’s particular use or occupancy of the Premises (as opposed to the
Permitted Uses) or any negligence or willful misconduct of Tenant or any Agent, or if any improvements made by Landlord to comply with such Laws benefit solely the Premises (and not any other premises) and are atypical of those performed for
similarly situated tenants, then such compliance shall be at Tenant’s cost. Landlord represents and warrants that, as of the Lease Commencement Date, the Premises and the Building shall be in material compliance with 

  

 12. 

			
		  	CONFIDENTIAL MATERIAL HAS BEEN OMITTED AND
		  	FILED SEPARATELY WITH THE SECURITIES AND
		  	EXCHANGE COMMISSION. BOXES AND ASTERIXES

all Laws. Notwithstanding any other provisions herein to the contrary, the parties hereto acknowledge and agree that in the event the Premises and/or the
Building are not in compliance with all laws as of the Lease Commencement Date, and provided that any non-compliance is not a result of Tenant’s breach of its obligations under this Lease or any negligence or willful misconduct of Tenant or any
Agent, Landlord shall bear any and all costs and expenses of achieving such compliance, and such costs and expenses shall not be included as an Operating Expense. If any such Law requires an occupancy or use permit or license for the Premises or the
operation of the business conducted therein, then Tenant shall obtain and keep current such permit or license at Tenant’s expense and shall promptly deliver a copy thereof to Landlord, provided, that Landlord shall be responsible, at its sole
cost and expense and not to be included as an Operating Expense, for obtaining the initial certificate of occupancy required for the Premises and Tenant’s use of the Premises for the Permitted Uses. Use of the Premises is subject to all
covenants, conditions and restrictions of record. Tenant shall not use any space in the Building or the Land for the sale of goods to the public at large or for the sale at auction of goods or property of any kind. Tenant shall not conduct any
operations, sales, promotions, advertising or special events outside the Premises, in the Building or on the Land. 
 6.2 Tenant shall
pay before delinquency any business, rent or other taxes or fees that are now or hereafter levied, assessed or imposed upon Tenant’s use or occupancy of the Premises, the conduct of Tenant’s business at the Premises, or Tenant’s
equipment, fixtures, furnishings, inventory or personal property. If any such tax or fee is enacted or altered so that such tax or fee is levied against Landlord or so that Landlord is responsible for collection or payment thereof, then Tenant shall
pay, as Additional Rent the amount of such tax or fee. 
 6.3 (a) Tenant shall not allow, cause or permit any Hazardous Materials to
be generated, used, treated, released, stored or disposed of in or about the Building or the Land, provided that Tenant may use and store normal and reasonable quantities of Hazardous Materials in the Premises as are customarily maintained by data
center tenants and as may be reasonably necessary for Tenant to conduct normal operations in the Premises taking into account the Permitted Uses, so long as such Hazardous Materials are properly, safely and lawfully stored and used by Tenant. At the
expiration or earlier termination of this Lease, with respect to conditions existing on account of Tenant’s use or occupancy of the Premises, Tenant shall surrender the Premises to Landlord free of Hazardous Materials attributable to an
Environmental Default and in full compliance with all Environmental Laws. 
 (i) “Hazardous Materials” means
(a) asbestos and any asbestos containing material and any substance that is then defined or listed in, or otherwise classified pursuant to, any Environmental Law or any other applicable Law as a “hazardous substance,” “hazardous
material,” “hazardous waste,” “infectious waste,” “toxic substance,” “toxic pollutant” or any other formulation intended to define, list, or classify substances by reason of deleterious properties such as
ignitability, corrosivity, reactivity, carcinogenicity, toxicity, reproductive toxicity, or Toxicity Characteristic Leaching Procedure (TCLP) toxicity, (b) any petroleum and drilling fluids, produced waters, and other wastes associated with the
exploration, development or production of crude oil, natural gas, or geothermal resources, and (c) any petroleum product, polychlorinated biphenyls, urea formaldehyde, radon gas, radioactive material (including any source, special nuclear, or
by product material), medical waste, chlorofluorocarbon, lead or lead based product, and any other substance whose presence could be detrimental to the Building or the Land or hazardous to health or the environment.

 (ii) “Environmental Law” means any present and future Law and any
amendments (whether common law, statute, rule, order, regulation or otherwise), permits and other requirements or guidelines of governmental authorities applicable to the Building or the Land and relating to the environment and environmental
conditions or to any Hazardous Material (including, without limitation, CERCLA, 42 U.S.C. § 9601 et seq., the Resource Conservation and Recovery Act of 1976, 42 U.S.C. § 6901 et seq., the Hazardous Materials Transportation Act, 49 U.S.C.
§ 1801 et seq., the Federal Water Pollution Control Act, 33 U.S.C. § 1251 et seq., the Clean Air Act, 42 U.S.C. § 7401 et seq., the Toxic Substances Control Act, 15 U.S.C. § 2601 et seq., the Safe Drinking Water Act, 42 U.S.C.
§ 300f et seq., the Emergency Planning and Community Right To Know Act, 42 U.S.C. § 1101 et seq., the Occupational Safety and Health Act, 29 U.S.C. § 651 et seq., and any so called “Super Fund” or “Super Lien” law,
any Law requiring the filing of reports and notices relating to hazardous substances, environmental laws administered by the Environmental Protection Agency, and any similar state and local Laws, all amendments thereto and all regulations, orders,
decisions, and decrees now or hereafter promulgated thereunder concerning the environment, industrial hygiene or public health or safety). 
 (iii) “Environmental Default” means any material violation of any Environmental Law by Tenant or any Tenant invitee (other than Landlord or Landlord’s agents, contractors, employees or agents) including,
without limitation, a release, spill, or discharge of a Hazardous Material on or from the Premises, the Land or the Building. 
 (b)
Notwithstanding any termination of this Lease, Tenant shall indemnify and hold Landlord, its employees and agents harmless from and against any damage, injury, loss, liability, charge, demand or claim based on or arising out of the presence or
removal of, or failure to remove, Hazardous Materials generated, used, released, spilled, stored or disposed of by Tenant or any Tenant invitee (other than Landlord or Landlord’s agents, contractors, employees or agents) in or about the
Building, after the date hereof. In addition, Tenant shall give Landlord prompt written notice of any actual or threatened Environmental Default of which Tenant has actual knowledge, which Environmental Default Tenant shall cure in accordance with
all Environmental Laws. Upon any Environmental Default, in addition to all other rights available to Landlord under this Lease, at law or in equity, Landlord shall have the right but not the obligation to immediately enter the Premises, to supervise
and approve any actions taken by Tenant to address the Environmental Default, and, if Tenant fails to promptly address same to Landlord’s reasonable satisfaction, to perform, at Tenant’s sole cost and expense, any lawful action necessary
to address same. If any lender or governmental agency shall require testing to ascertain whether an Environmental Default is pending or threatened, and such testing discloses the existence of an Environmental Default, then Tenant shall pay the
reasonable costs of such testing as Additional Rent. 
 (c) Notwithstanding anything to the contrary contained herein, Landlord
represents and warrants to Tenant that Landlord has no knowledge of the current existence of any Hazardous Materials in or about the Property. Notwithstanding anything to the contrary

contained herein, Landlord shall indemnify and hold Tenant, its employees and agents harmless from and against any damage, injury, loss, liability, charge,
demand or claim based on, or arising out of, the presence or removal of, or failure to remove, Hazardous Materials generated, used, released, stored or disposed of by Landlord, any Landlord invitee or any other party (other than Tenant or
Tenant’s agents, contractors, employees, invitees or guests) prior to or after the Lease Commencement Date. In addition, Landlord shall give Tenant prompt written notice of any actual or threatened violation of any Environmental Law affecting
the Premises of which Landlord has actual knowledge, which violation Landlord shall cure in accordance with all Environmental Laws. For purposes of this Section 6.3(c), Hazardous Materials excludes substances of a type and in a quantity
normally used in connection with the occupancy or operation of data centers, which substances are being held, stored and used in compliance with federal, state and local Laws. 
 ARTICLE VII 
 ASSIGNMENT AND SUBLETTING 
 7.1 Subject to the terms and provisions of Sections 7.2(b) and 7.6 below, Tenant shall not assign, transfer or otherwise encumber (collectively,
“assign”) this Lease or all or any of Tenant’s rights hereunder or interest herein, or sublet or permit anyone to use or occupy (collectively, “sublet”) the Premises or any part thereof, without
obtaining the prior written consent of Landlord, which consent, provided no Event of Default exists under this Lease, and subject to Landlord’s rights and Tenant’s obligations pursuant to Sections 7.3, 7.4 and 7.5 below, Landlord shall not
unreasonably withhold, condition or delay. For purposes of the immediately preceding sentence, it shall be reasonable for Landlord to withhold its consent if, for example: (i) the proposed subtenant or assignee is engaged in a business, or the
Premises will be used in a manner, that is inconsistent with the use of the Property as a first-class data center; or (ii) Landlord is not reasonably satisfied with the financial condition of the proposed subtenant or assignee taking into
account the remaining obligations under this Lease and the fact that Tenant is not released; or (iii) the proposed use of the Premises is not in compliance with Article VI or is not compatible with the other uses within, and the terms of other
leases with respect to, the Building; or (iv) the initial Tenant does not remain fully liable as a primary obligor for the payment of all rent and other charges payable by Tenant under this Lease and for the performance of all other obligations
of Tenant under this Lease; or (v) the proposed subtenant or assignee is a governmental or quasi governmental agency; or (vi) the holders of Mortgages encumbering the Building shall fail to consent (Landlord hereby agreeing to use
commercially reasonable, diligent efforts to obtain such consent if Landlord approves such transaction); or (vii) the proposed subtenant or assignee is either (A) an existing tenant of the Building (or any parent, subsidiary or affiliate
thereof) if Landlord has adequate space available in the Building for a comparable term, or (B) for a period of forty-five (45) days following the submission of a written proposal for the lease of space (and thereafter if a mutual
agreement such as a letter of intent is executed within such period), any person or entity with which Landlord is in the process of negotiating for the rental of space in the Building. Except as otherwise set forth herein, no assignment or right of
occupancy hereunder may be effectuated by operation of law or otherwise without the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed. Any assignment or subletting, Landlord’s consent
thereto, the listing or

posting of any name other than Tenant’s, or Landlord’s collection or acceptance of rent from any assignee or subtenant, shall not be construed
either as waiving or releasing Tenant from any of its liabilities or obligations under this Lease as a principal and not as a guarantor or surety, or as relieving Tenant or any assignee or subtenant from the obligation of obtaining Landlord’s
prior written consent to any subsequent assignment or subletting. As security for this Lease, Tenant hereby assigns to Landlord the rent due from any assignee or subtenant of Tenant. During any period that there exists an Event of Default under this
Lease, Tenant hereby authorizes each such assignee or subtenant to pay said rent directly to Landlord upon receipt of notice from Landlord specifying same. Landlord’s collection of such rent shall not be construed as an acceptance of such
assignee or subtenant as a tenant. Tenant shall not mortgage, pledge, hypothecate or encumber (collectively “mortgage”) this Lease without Landlord’s prior written consent, which consent may be granted or withheld in
Landlord’s sole but reasonable discretion. Any sublease, assignment or mortgage shall, at Landlord’s option, be effected on forms reasonably approved by Landlord. Tenant shall deliver to Landlord a fully executed copy of each agreement
evidencing a sublease, assignment or mortgage, and Landlord’s consent thereto, within thirty (30) days after execution thereof. 
 7.2 (a) If Tenant is a partnership or a limited liability company, then any event (whether voluntary, concurrent or related) resulting in a dissolution of Tenant, any withdrawal or change (whether voluntary, involuntary or by
operation of law) of the partners or members, as applicable, owning a controlling interest in Tenant (including each general partner or manager, as applicable), or any structural or other change having the effect of limiting the liability of the
partners shall be deemed a voluntary assignment of this Lease subject to the provisions of this Article VII. If Tenant is a corporation or a partnership with a corporate general partner, then any event (whether voluntary, concurrent or related)
resulting in a dissolution, merger, consolidation or other reorganization of Tenant (or such corporate general partner) and that causes a change in control of Tenant, or the sale or transfer or relinquishment of the interest of shareholders who, as
of the date of this Lease, own a controlling interest of the capital stock of Tenant (or such corporate general partner) and that causes a change in control of Tenant, shall be deemed a voluntary assignment of this Lease subject to the provisions of
this Article VII; provided, however, that if Tenant is a corporation, or a wholly-owned subsidiary of a corporation, whose stock is traded through a national or regional exchange or over the counter market, then the foregoing portion of this
sentence shall be applicable only if such event has or is intended to have the effect of eliminating liability under this Lease. 
 (b)
Notwithstanding anything contained in this Article VII to the contrary, provided no Event of Default exists hereunder, Tenant may, upon not less than ten (10) days’ prior written notice to Landlord (which notice shall contain a written
certificate from Tenant, signed by an authorized representative of Tenant, containing a representation as to the true, correct and complete legal and beneficial relationship of Tenant and the proposed assignee, transferee or subtenant) but without
Landlord’s prior written consent and without being subject to Landlord’s rights and Tenant’s obligations set forth in Sections 7.4 and 7.5 below, assign or transfer its entire interest in this Lease or sublease the entire or any
portion of the Premises to any of the following (each, an “Affiliate”): (i) to a corporation or other business entity (herein sometimes referred to as a “successor corporation”) into or with which
Tenant shall be merged or consolidated, or to which substantially all of the assets of Tenant may be transferred or sold, 

  

 16. 

			
		  	CONFIDENTIAL MATERIAL HAS BEEN OMITTED AND
		  	FILED SEPARATELY WITH THE SECURITIES AND
		  	EXCHANGE COMMISSION. BOXES AND ASTERIXES
		  	DENOTE SUCH OMISSION

  

 
provided that such successor corporation shall have a net worth and liquidity factor at least equal to the net worth and liquidity factor of Tenant as of the
date hereof or otherwise reasonably acceptable to Landlord taking into account the fact that the original Tenant under this Lease is not being released, and provided that the successor corporation shall assume in writing all of the obligations and
liabilities of Tenant under this Lease and the proposed use of the Premises is in compliance with Article VI above; or (ii) to a corporation or other business entity (herein sometimes referred to as a “related
corporation”) which shall control, be controlled by or be under common control with Tenant, provided that such related corporation shall assume in writing all of the obligations and liabilities of Tenant under this Lease (without
relieving Tenant therefrom) and the proposed use of the Premises is in compliance with Article VI above. In the event of any such assignment or subletting, Tenant shall remain fully liable as a primary obligor for the payment of all rent and other
charges required hereunder and for the performance of all obligations to be performed by Tenant hereunder. For purposes of this Section 7.2, “control” shall be deemed to be ownership of more than fifty percent (50%) of the stock
or other voting interest of the controlled corporation or other business entity. Notwithstanding the foregoing, if Tenant structures one or more assignment or sublease transactions to an entity that meets the definition of Affiliate as specified
above for the purpose of circumventing the restrictions on subleases and assignments provided elsewhere in this Article VII, then such subtenant(s) or assignee(s) shall conclusively be deemed not to be an Affiliate and subject to all such
restrictions. 
 7.3 (a) If at any time during the Lease Term Tenant desires to assign, sublet or mortgage all or part of this Lease
or the Premises, then in connection with Tenant’s request to Landlord for Landlord’s consent thereto, Tenant shall give notice to Landlord in writing (“Tenant’s Request Notice”) containing: the identity of the
proposed assignee, subtenant or other party and a description of its business; the terms of the proposed assignment, subletting or other transaction (including a copy of the proposed document for same), including whether any premium or other
consideration is being paid for the assignment, sublease or other transaction; the anticipated commencement date of the proposed assignment, subletting or other transaction (the “Proposed Sublease Commencement Date”); the
area proposed to be assigned, sublet or otherwise encumbered (the “Proposed Sublet Space”); and financial statements for the prior two (2) years certified by an authorized officer of Tenant or a certified public
accounting firm, or other evidence of financial responsibility, of such proposed assignee, subtenant or other party. If financial statements for such proposed assignee, subtenant or other party are not available for the prior two years, then Tenant
shall submit any financial statements that are available for the prior two years and any other available evidence of financial responsibility reasonably requested by Landlord. 
 (b) Landlord shall grant or deny, with reasonable specificity, Tenant’s request for consent contained in any Tenant’s Request Notice
within thirty (30) days after Landlord has received any such Tenant’s Request Notice (including all other items required to be delivered by Tenant to Landlord as set forth in Section 7.3(a) above). If Landlord fails to timely grant or
deny such request with reasonable specificity, then Landlord shall be deemed to have granted its consent thereto.

 7.4 If the proposed term with respect to the Proposed Sublet Space extends (including any
renewal or extension options) beyond the first (1st) day of the twelfth (12th) calendar month before the then-scheduled expiration of the Lease Term, or if the Proposed Sublet Space is (or, when aggregated with other space being sublet or
assigned by Tenant, will be) more than fifty percent (50%) of the total number of rentable square feet in the Premises, or if the Critical Load Power associated with the Proposed Sublet Space is (or, when aggregated with the Critical Load Power
associated with other space being sublet or assigned by Tenant, will be) more than fifty percent (50%) of the Maximum Load Limit (hereinafter defined), then, in any such event, except as set forth in Section 7.2(b) concerning Affiliates,
Landlord shall have the right in its sole and absolute discretion to terminate this Lease with respect to the Proposed Sublet Space by sending Tenant written notice of such termination within thirty (30) days after Landlord’s receipt of
Tenant’s Request Notice. Notwithstanding any of the foregoing to the contrary, if Landlord sends Tenant a written notice pursuant to the immediately preceding sentence indicating Landlord’s intention to terminate this Lease with respect to
the Proposed Sublet Space, then Tenant shall have the right, for a period of ten (10) days after receipt of such notice, to withdraw (by written notice to Landlord) the applicable Tenant’s Request Notice. If the Proposed Sublet Space does
not constitute the entire Premises and Landlord exercises its option to terminate this Lease with respect to the Proposed Sublet Space, then (a) Tenant shall tender the Proposed Sublet Space to Landlord on the Proposed Sublease Commencement
Date and such space shall thereafter be deleted from the Premises, and (b) as to that portion of the Premises which is not part of the Proposed Sublet Space, this Lease shall remain in full force and effect except that Base Rent and additional
rent shall be reduced pro rata. Fifty percent (50%) of the cost of any construction required to permit the operation of the Proposed Sublet Space separate from the balance of the Premises shall be paid by Tenant to Landlord as additional rent
hereunder. If the Proposed Sublet Space constitutes the entire Premises and Landlord elects to terminate this Lease, then Tenant shall tender the Proposed Sublet Space to Landlord, and this Lease shall terminate, on the Proposed Sublease
Commencement Date. 
 7.5 If any sublease or assignment (whether by operation of law or otherwise, including without limitation an
assignment pursuant to the provisions of the Bankruptcy Code or any other Insolvency Law) provides that the subtenant or assignee thereunder is to pay any amount in excess of the sum of (a) the rent and other charges due under this Lease plus
(b) the reasonable out-of-pocket expenses (including any costs attributable to vacancy periods or “downtime”) that Tenant reasonably incurred in connection with the procurement of such sublease, assignment or other transfer (which
expenses shall be amortized on a straight-line basis over the initial sublease term for the purposes hereof), then whether such net excess be in the form of an increased monthly or annual rental, a lump sum payment, payment for the sale, transfer or
lease of Tenant’s fixtures, leasehold improvements, furniture and other personal property, or any other form of payment having the effect of a “disguised” rental payment (and if the subleased or assigned space does not constitute the
entire Premises, the existence of such excess shall be determined on a pro rata basis), Tenant shall pay to Landlord, along with the next monthly installment of Base Rent due, [*****] of any such net excess or other premium applicable to the
sublease or assignment, which amount shall be calculated and paid by Tenant to Landlord on a monthly basis as Additional Rent. Acceptance by Landlord of any payments due under this Section 7.5 shall not be deemed to constitute approval by
Landlord of any sublease or assignment, nor shall such acceptance waive any rights of Landlord hereunder. Landlord shall have the right to inspect and audit Tenant’s books and records relating to any sublease or assignment.

 7.6 Landlord acknowledges that the business to be conducted by Tenant in the Premises may
include the installation of certain equipment (described below) owned, licensed or otherwise used by customers, vendors or co-locators of the undersigned Tenant (“Permitted Licensees”) in the Premises, in order for Permitted
Licensees to place, use, operate and/or maintain computer, switch, communications and/or other related facilities and equipment which may interconnect with Tenant’s equipment and facilities and/or other Permitted Licensees’ equipment and
facilities (the “Permitted Interconnection”). To expedite access of Permitted Licensees’ access to the Premises for Permitted Interconnections, Landlord expressly agrees that Tenant may, without Landlord’s consent,
license portions of the Premises to Permitted Licensees for the sole purpose of Permitted Interconnections pursuant to written agreements or other arrangements by and between Tenant and Permitted Licensees (collectively, “Permitted
Agreements”); provided, however, that (a) Tenant acknowledges and agrees that access of Permitted Licensees to the Building and the Premises is subject to the terms and provisions of Article V above and (b) the Permitted
Licensee’s license of a portion of the Premises may not violate the terms of this Lease or any Applicable Laws. The Permitted Agreements and the Permitted Licensees’ rights thereunder shall be subject and subordinate at all times to the
Lease and all of its provisions, covenants and conditions. Except to the extent caused by the negligence or willful acts or omissions of Landlord or its agents, and subject to Section 12.3 below, Tenant hereby agrees to indemnify, defend, and
hold harmless Landlord from and against (and to reimburse Landlord for) any and all claims, costs, damages, causes of action and/or litigation arising from or in any manner relating to (i) any Permitted Agreement, (ii) the use of the
Premises or any other portion of the Building or the Property by any Permitted Licensee or any person claiming by, through or under any Permitted Licensee, its officers, agents or employees (collectively, the “Colocating
Parties”), and (iii) the acts or omissions of any Permitted Licensee or any Colocating Parties. Notwithstanding anything to the contrary contained herein, Landlord and Tenant acknowledge and agree that Permitted 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. Additionally, Landlord and Tenant agree that Tenant’s right to enter into Permitted Agreements related
to the Premises is a right that is granted specifically and solely to Rackspace U.S., Inc. and Rackspace Hosting, Inc. and Affiliates of each, and, as such, such right shall not be exercisable by any party (who is not an Affiliate of Rackspace U.S.,
Inc. and/or Rackspace Hosting, Inc.) to whom any or all of the rights of “Tenant” under this Lease are hereafter assigned or otherwise transferred, or by any Colocating Party (who is not an Affiliate of Rackspace U.S., Inc. and/or
Rackspace Hosting, Inc.). 
 7.7 All restrictions and obligations imposed pursuant to this Lease on Tenant shall be deemed to extend
to any subtenant, assignee, licensee, concessionaire or other occupant or transferee, and Tenant shall cause such person to comply with such restrictions and obligations. Any assignee shall be deemed to have assumed obligations as if such assignee
had originally executed this Lease and at Landlord’s request shall execute promptly a document confirming such assumption. Each sublease is subject to the condition that if the Lease Term is terminated or Landlord succeeds to Tenant’s
interest in the Premises by voluntary surrender or otherwise, at Landlord’s option the subtenant shall be bound to Landlord for the balance of the term of such sublease and shall attorn to and recognize Landlord as its landlord under the then
executory terms of such sublease.

 ARTICLE VIII

 8.1 Subject to Landlord’s obligations in Section 8.2,
Article XVI and Article XVII below and in the Services Exhibit attached hereto as Exhibit F, Tenant, at Tenant’s sole cost and expense, shall promptly make all repairs, perform all maintenance, and make all replacements in and to the
Premises that are necessary or desirable to keep the Premises in proper operating condition and repair, in a clean, safe and tenantable condition, and otherwise in accordance with all Laws and the requirements of this Lease (Tenant’s repair,

shall provide Landlord with copies of all maintenance and service contracts. In the event that Tenant fails to commence and diligently prosecute to completion any item of Tenant’s Repair and Maintenance Obligations within fifteen
(15) Business Days following Tenant’s receipt of notice from Landlord, then Landlord shall have the right, at Landlord’s option, to perform any such item of Tenant’s Repair and Maintenance Obligations and to charge Tenant for all
reasonable costs and expenses actually incurred by Landlord in connection therewith. Tenant shall give Landlord prompt written notice of any defects or damage to the structure of, or equipment or fixtures in, the Building or any part thereof of
which Tenant has knowledge. Tenant shall suffer no waste or injury to any part of the Premises, and shall, at the expiration or earlier termination of the Lease Term, surrender the Premises in an order and condition equal to or better than their
order and condition on the Lease Commencement Date, except for ordinary wear and tear and as otherwise provided in Article IX, Article XII and/or Article XVI. Except as otherwise provided in Article XVI, all injury, breakage and damage to the

any act or omission of any agent, employee, subtenant, assignee, contractor, client, licensee, customer, invitee or guest of Tenant (collectively,
“Agents”) or Tenant, shall be repaired by and at Tenant’s expense, except that: (A) if either an emergency condition exists or the Lease Term has expired or Tenant fails to commence and diligently prosecute to
completion repair of any such injury, breakage or damage within ten (10) days following Tenant’s receipt of notice from Landlord, then Landlord shall have the right at Landlord’s option to make any such repair and to charge Tenant for
all reasonable costs and expenses actually incurred by Landlord in connection therewith; and (B) if such injury, breakage and damage is caused by the negligence of Tenant or any Agent (as opposed to the gross negligence or willful misconduct of
Tenant or any Agent), then the mutual waiver of subrogation specified in Sections 12.2 and 12.3 shall apply (subject to the limitations of the remainder of Article XII, including, without limitation, the fact that Tenant’s insurance shall be
primary and non-contributory). Landlord shall provide and install replacement tubes for Building-standard fluorescent light fixtures (subject to reimbursement pursuant to Article IV). All other lights and/or light bulbs within the Premises shall be
provided and installed by Tenant at Tenant’s sole cost and expense. The provision, installation and replacement of such lights and light bulbs shall be expressly required as an item of Tenant’s Repair and Maintenance Obligations.

consistent with industry standards for first-class data centers (Landlord’s repair, maintenance and replacement obligations, collectively, “Landlord’s Repair and Maintenance Obligations”). Landlord’s Repair and
Maintenance Obligations shall include Landlord’s duties and obligations set forth in Section B of the Services Exhibit attached hereto as Exhibit F. Notwithstanding any of the foregoing to the contrary, maintenance and repair of all
Tenant Items shall be the sole responsibility of Tenant and Tenant Items shall be deemed not to be a part of the Building Structure and Systems. 
 ARTICLE IX 
 ALTERATIONS 
 9.1 Except for installation of the Building-standard number of PDUs in Pod 8b, Landlord represents and warrants that it has constructed and installed at its sole cost and expense,

the Building and infrastructure and leasehold improvements (“Landlord’s Work”) as outlined in Exhibit D attached hereto
and made a part hereof, in a good, workmanlike and first-class manner, and in compliance with all applicable Laws and building codes. It is understood and agreed that, except for: (i) installation of the Building-standard number of PDUs in Pod
8b in accordance with Section 2.2(c) above and (ii) delivery of the Office Space and Storage Space as set forth in Sections 1.3 and 1.4 above, respectively, Landlord will not make, and is under no obligation to make, any structural or
other alterations, installations, additions or improvements in or to the Building, Land or Premises other than Landlord’s Work. 
 9.2 Tenant shall not make or permit anyone to make any material alterations, additions, improvements or replacements in or to the Premises, the Building, or the Property (collectively, “Alterations”) without
the prior written consent of Landlord, which consent may be withheld or granted in Landlord’s sole and absolute discretion with respect to structural Alterations and those non-structural Alterations which are visible from the exterior of the
Premises, and which consent shall not be unreasonably withheld, conditioned or delayed with respect to all other non-structural Alterations. Structural Alterations shall be deemed to include, without limitation, any Alteration that will or may
necessitate any changes, replacements or additions to the load-bearing or exterior walls, non-drop ceilings, partitions (load-bearing or non-demising), columns or floor, or to the fire protection, water, sewer, electrical, mechanical, plumbing or
HVAC systems, of the Premises or the Building. Notwithstanding the foregoing, Tenant shall have the right to make Minor Changes (as defined below) within the Premises without requiring the consent of Landlord. “Minor Changes”
shall mean those minor, non-structural Alterations which will not cause an interruption of, or a reduction in, the functioning of the Building’s mechanical, electrical, life safety, security, plumbing, HVAC, telecommunications or other systems,
and which cost (including installation) in the aggregate less than [*****] (as reasonably determined by Landlord). The construction of any cage(s), security fencing or similar structure within the Premises shall not be a Minor Change and shall be
subject to Landlord’s consent, such consent not to be unreasonably withheld, conditioned or delayed. Any Alterations made by Tenant shall be made: (a) in a good, workmanlike, first class and prompt manner; (b) using new or comparable
materials only; (c) by a contractor included on Landlord’s list of approved contractors or a contractor otherwise reasonably approved in writing by Landlord (each, an “Approved Contractor”); (d) on days and at
times that do not unreasonably interfere with Landlord’s performance of its obligations under this Lease; (e) under the supervision of an architect reasonably approved in writing by Landlord; (f) in accordance with plans and
specifications prepared by an engineer and/or architect reasonably acceptable to Landlord, and, with respect to Alterations that are not Minor Changes, which plans and specifications shall be approved in writing by Landlord at Landlord’s
standard charge, which shall not exceed [*****] except in the event that Landlord reasonably obtains the services of a non-affiliated third party it its review of the plans and specifications (i.e., where Alteration affects the Building Structure
and Systems), Tenant shall be responsible for all reasonable, third-party, out-of-pocket costs and expenses actually incurred by Landlord; (g) in accordance with all Laws and, if made available to Tenant by Landlord, the reasonable requirements
of any insurance company insuring the Building or any portion thereof; (h) with respect to any Alterations that are not Minor Changes, after Landlord shall have obtained any required consent of the holder of any Mortgage of whom Tenant has
notice; (i) after obtaining public liability and worker’s compensation insurance policies approved in writing by Landlord, which policies shall

		  	EXCHANGE COMMISSION. BOXES AND ASTERIXES

cover every person who will perform any work with respect to such Alteration; and (j) with the obligation for Tenant to obtain and deliver to Landlord
written, unconditional full or partial (as applicable) waivers of mechanics’ and materialmen’s liens against the Premises, the Building and the Property from all contractors, subcontractors, laborers and material suppliers (individually
and collectively, “Contractors”) for all work, labor and services performed and materials furnished in connection with Alterations within ten (10) Business Days after Tenant submits payment to the applicable
Contractor(s) for the applicable portion(s) of the Alterations. If any lien (or a petition to establish such lien) is filed in connection with any Alteration made by or on behalf of Tenant, such lien (or petition) shall be discharged by Tenant as
soon as commercially reasonable, but in no event more than thirty (30) days after Tenant receives notice thereof, at Tenant’s sole cost and expense, by the payment thereof or by the filing of a bond legally sufficient to discharge such
lien. If Landlord gives its consent to the making of any Alteration, such consent shall not be deemed to be an agreement or consent by Landlord to subject its interest in the Premises, or the Building to any liens which may be filed in connection
therewith. Tenant acknowledges that any Alterations are accomplished for Tenant’s account, Landlord having no obligation or responsibility in respect thereof. Landlord’s approval of any plans and drawings (and changes thereto) regarding
any Alterations or any contractor or subcontractor performing such Alterations shall not constitute Landlord’s representation that such approved plans, drawings, changes or Alterations comply with all Laws. Any deficiency in design or
construction, although same had prior approval of Landlord, shall be solely the responsibility of Tenant, unless Landlord performed design work or construction work (other than reviewing and/or approving plans, drawings or construction work) with
respect to such Alterations. All Alterations involving structural, electrical, mechanical or plumbing work, the heating, ventilation and air conditioning system of the Premises or the Building, fire and life safety system or the roof of the Building
shall, at Landlord’s election, be performed by Landlord’s designated contractor or subcontractor, who shall be reasonably approved by Tenant, at Tenant’s expense (provided the cost therefor is competitive). For any approved
Alterations performed by Tenant and/or its contractor(s), Tenant shall not be required to pay a construction supervision fee or coordination fee to Landlord; however, if Landlord’s contractor or subcontractor performs any Alteration, then
Tenant shall pay a reasonable construction supervision fee [*****]. Promptly after the completion of an Alteration, Tenant, at its expense, shall deliver to Landlord three (3) sets of as-built (or record) drawings and CAD drawings prepared by
Tenant’s engineer showing such Alteration in place. Notwithstanding the foregoing, subject to Landlord’s written approval, which shall not be unreasonably withheld or delayed, Tenant may elect not to cause as-built drawings and CAD
drawings to be prepared for Minor Changes that, in Landlord’s sole but reasonable discretion, do not affect the Building Structure and Systems. 
 9.3 If any Alterations that require Landlord’s consent are made without the prior written consent of Landlord then, if either an emergency condition exists or the Lease Term has expired or Tenant fails to
commence and diligently prosecute to completion, removal and correction of such Alterations and restoration of the Premises and the Building within ten (10) days following Tenant’s receipt of notice from Landlord, Landlord shall have the
right, at Tenant’s expense, to so remove and correct such Alterations and restore the Premises and the Building to their condition immediately prior thereto. All tenant improvements to the Premises made by Landlord shall immediately become the
property of Landlord and shall remain upon and

be surrendered with the Premises as a part thereof at the expiration or earlier termination of the Lease Term. Tenant shall have the right to remove, at or
prior to the expiration or earlier termination of the Lease Term, all movable furniture, furnishings, trade fixtures, facilities and equipment installed in the Premises or elsewhere in the Building or on the Land solely at the expense of Tenant,
including all Tenant Items, and Tenant may remove, at its expense, all Alterations and other items (including any telecommunications equipment and wiring) made or installed by Tenant in the Premises or the Building, provided, that Tenant may, at its
option, surrender those Alterations and/or Tenant Items or other Tenant facilities or equipment requested by Landlord in writing. 
 9.4
[*****] 
 9.5 Landlord waives, releases and relinquishes any statutory, common law or constitutional liens it may have or at any
time hereafter be entitled to assert against the personal property, trade fixtures and telecommunications, computer or other equipment and facilities which Tenant, its agents, employees and/or its Permitted Licensees, install in the Premises or
elsewhere in the Building or on the Land, or is otherwise located in the Premises. 
 ARTICLE X 
 SIGNS 
 Tenant shall not place,
inscribe, paint, affix or otherwise display any sign, advertisement or notice of any kind on any part of the exterior or the interior of the Building without the prior written approval of Landlord, which may be granted or withheld in Landlord’s
sole and absolute discretion, provided, that Tenant may display signs within the Premises without Landlord’s consent; however, the location of any such sign displayed within the Premises is subject to Landlord’s approval, not to be
unreasonably withheld or delayed. All signage installed by Tenant in accordance with this Article X shall be installed and removed at the expiration or earlier termination of the Lease Term, and Tenant shall repair any damage to the Building
resulting therefrom, at Tenant’s cost and expense. If any sign, advertisement or notice requiring Landlord’s approval as aforesaid is exhibited or installed by Tenant without Landlord’s prior approval, Landlord shall have the right to
immediately remove the same at Tenant’s expense. Landlord reserves the right to affix, install and display signs, advertisements and notices on any part of the exterior or interior of the Building, including those required by applicable law,
provided, that Landlord shall not affix, install or display any signs, advertisements or notices not required by applicable law and identifying Tenant, Tenant’s Affiliates or Tenant’s customers on or within the Building without
Tenant’s prior written consent, which consent may be granted or withheld in Tenant’s sole and absolute discretion. 
 ARTICLE XI

 LANDLORD ACCESS 
 11.1 Tenant will permit Landlord, or its agents or representatives, and the holder of any Mortgage, to enter the Premises, without charge therefor to Landlord and without diminution of the rent payable by Tenant, (i) to examine,

(ii) to make such alterations, replacements and/or repairs as in Landlord’s reasonable judgment may be required by law or be necessary in order for
Landlord to perform its obligations under Article VIII hereof, and (iii) to otherwise comply with and carry out Landlord’s obligations under this Lease. In connection with any such entry, Landlord shall (A) diligently endeavor to
minimize the disruption to Tenant’s use of the Premises and, in all events, shall not materially interfere with Tenant’s use of, or access to, the Premises for the Permitted Uses, (B) except in the event of emergency, give Tenant
reasonable advance written, telephonic or email notice of such entry pursuant to Section 5.4 above, which shall not be less than two (2) Business Days prior to the date of entry and (C) diligently endeavor to conduct such entry only
during normal working hours (except in the event of an emergency). Tenant may, at its option, require that Landlord be accompanied by a representative of Tenant during any such entry (except in the case of emergency), provided that such
representative of Tenant does not interfere with or delay Landlord in exercising its rights or satisfying its obligations hereunder. 
 11.2 Landlord reserves the right to grant easements, rights, and dedications that Landlord deems necessary or desirable for the benefit of the Property, and to record personal maps and restrictions in connection therewith; provided,
however, Landlord shall not enter into any such agreement or grant any such rights that would unreasonably interfere with Tenant’s use or occupancy of, or access to, the Premises in accordance with the Permitted Uses. 
 11.3 Upon written request by Tenant, Landlord shall grant, subject to Landlord’s rules and regulations and upon commercially reasonable
terms, as determined by Landlord in its sole but reasonable discretion, license rights coterminous with the Lease Term to one or more reputable telecommunications utility provider(s) designated by Tenant (any such utility provider, an
“Approved Fiber Provider”), to permit any such Approved Fiber Provider to bring such Approved Fiber Provider’s telecommunications fiber, cable and related equipment and facilities from and through conduits [*****] duct
banks on the Property (the “Telecommunications Duct Banks”) into [*****] the Building’s telecommunications points of entry (each, a “POE”), to provide cross-connects within the Premises and to
permit any such Approved Fiber Provider to maintain and operate such cable, fiber and related facilities and equipment on the Property. Landlord agrees that Landlord shall not charge Tenant or any Approved Fiber Provider any fee and/or other amount
in connection with any such license granted pursuant to this Section 11.3 (other than direct costs incurred in connection with maintaining and restoring the Property, systems, and equipment directly affected by such license). Tenant shall have
the right, subject to Landlord’s reasonable rules and regulations, to use the secure telecommunications conduits exclusively serving the Premises and extending to two (2) POEs within the Building (the “Telecommunications
Conduits”) in order to connect Tenant’s telecommunications network cables and related telecommunications and computer facilities and equipment to the telecommunications equipment and facilities of third parties located within the
two (2) POEs (“AFP Telecommunications Facilities”). Tenant shall not be charged any fee for the use of the Telecommunications Duct Banks, the Telecommunications Conduits and/or the POEs in accordance with this
Section 11.3. Furthermore, Tenant shall have the right, subject to Article IX above and Landlord’s reasonable rules and regulations, and accompanied by an employee of Landlord or the Management Company or an agent designated by Landlord or
the Management Company, to enter the POEs solely to install, use, operate, maintain, inspect, repair, replace and remove telecommunications facilities and equipment reasonably approved by Landlord in order

to connect to AFP Telecommunications Facilities located within the POEs, all in locations reasonably designated by Landlord. Tenant acknowledges and agrees
that, in connection with its use of the Telecommunications Conduits and the POEs: (a) any of Tenant’s telecommunications network cables and wires entering the POEs must terminate in optical cable entrance termination facilities reasonably
approved by Landlord, (b) Tenant may use only non-heat rejecting fiber termination facilities within the POEs, and (c) Tenant shall not materially disrupt, interfere with, or adversely affect (i) the operations of Landlord or other
tenants within the Building, (ii) the structure of the Premises or the Building, and/or (iii) the telecommunications equipment and facilities or other personal property of Landlord or other tenants within the Building. Tenant shall be
responsible, at its sole cost and expense, for (1) connections to Approved Fiber Providers and for any services provided by Approved Fiber Providers to Tenant and (2) all costs associated with the population of the Telecommunications
Conduits, including the installation of innerducts. [*****] 
 ARTICLE XII 
 INSURANCE 
 12.1 Tenant shall not conduct or permit to be conducted any
activity, or place or permit to be placed any equipment or other item in or about the Premises or the Building, which is inconsistent with the Permitted Uses and which will in any way increase the rate of property insurance or other insurance on the
Building. If any increase in the rate of property or other insurance is due to any specific activity, equipment or other item of Tenant, then (whether or not Landlord has consented to such activity, equipment or other item) Tenant shall pay, as
Additional Rent due hereunder, the amount of such increase. The statement of any applicable insurance company or insurance rating organization (or other organization exercising similar functions in connection with the prevention of fire or the
correction of hazardous conditions) that an increase is due to any such specific activity, equipment or other item shall be conclusive evidence thereof. 
 12.2 (a) Throughout the Lease Term, Tenant shall obtain and maintain: (1) commercial general liability insurance (written on an occurrence basis) including contractual liability coverage insuring the

automobiles owned, hired or used by Tenant in carrying on its business, if any); (5) worker’s compensation insurance (covering Tenant’s employees); (6) employer’s liability insurance (covering Tenant’s employees); and
(7) umbrella excess liability coverage on a following form basis in excess of the primary commercial liability, business auto liability, and employer’s liability coverages specified above and which insures against bodily injury, property
damage, personal injury and advertising injury claims. Such commercial general liability insurance shall be in amounts of One Million Dollars ($1,000,000) combined single limit per occurrence, and Two Million Dollar ($2,000,000) annual general
aggregate (on a per location basis). Such business interruption insurance shall be in minimum amounts typically

carried by prudent tenants engaged in similar operations, but in no event shall be in an amount less than the Base Rent then in effect during any Lease Year.
Such property insurance shall be in an amount not less than that required to replace all tenant improvements installed by Tenant in the Premises, all Alterations (excluding Landlord’s Work) and all of Tenant’s contents within the Premises
(including, without limitation, Tenant’s trade fixtures, decorations, furnishings, inventory, equipment, facilities and personal property), but excluding PDUs, CRACs, HVAC cooling support equipment, fire detection and alarm and fire suppression
systems and equipment and any other equipment, facilities or other property of Landlord comprising the Building Structure and Systems and located within the Premises. Such automobile liability insurance shall be in an amount of One Million Dollars

liability and employer’s liability insurance. 
 (b) All such insurance shall: (1) be issued by a company that is licensed
to do business in the jurisdiction in which the Building is located, and that has a rating equal to or exceeding A:XII from the most current Best’s Insurance Guide; (2) with respect to Tenant’s commercial general liability insurance,
name Landlord, the Management Company and the holder of any Mortgage (as hereinafter defined) of which Tenant has notice as additional insureds; (3) contain a waiver of subrogation (Tenant hereby waiving its right of action and recovery against
and releasing Landlord and Landlord’s shareholders, partners, directors, officers and employees (“Landlord’s Representatives”) from liabilities, claims and losses for which they may otherwise be liable to the extent
that (i) Tenant is covered therefor by insurance carried or required to be carried under this Lease and (ii) provided that Tenant is carrying such required insurance, Tenant receives proceeds therefor); (4) be reasonably acceptable in
form and content to Landlord; (5) be primary and non-contributory; and (6) contain an endorsement requiring the insurance company to provide Landlord with written notice (by certified or registered mail, return receipt requested to the

minimum amounts or different types of insurance if it becomes customary for other landlords of comparable data centers in the Northern Virginia area to require similar tenants in similar industries to carry insurance of such higher minimum amounts
or of such different types. Tenant shall deliver an Accord 27 certificate of all such insurance (which certificate shall evidence an endorsement for each policy indicating that the Landlord Insured Parties are named as additional insureds on
liability policies (except employer’s liability, workers’ compensation and umbrella excess liability coverage) and that Landlord is named as a loss payee on the property insurance policies with respect to Landlord’s interest in
improvements and betterments) to Landlord on or before the Lease Commencement Date and at least annually thereafter. If Tenant fails to provide evidence of insurance required to be provided by Tenant hereunder, prior to the Lease Commencement Date
and, thereafter, within thirty (30) days following Landlord’s request during the Lease Term (and

in any event within thirty (30) days prior to the expiration date of any such coverage, any other cure or grace period provided in this Lease not being
applicable hereto), Landlord shall be authorized (but not required), after ten (10) days’ prior notice, to procure such coverage in the amount stated, with all costs thereof to be chargeable to Tenant and payable as Additional Rent within
thirty (30) days after receipt of written invoice therefor. 
 12.3 Throughout the Lease Term, Landlord agrees to carry and
maintain all-risk property insurance (with full replacement cost coverage) covering the Building, including the Building Structure and Systems, and any other equipment, fixtures and property of Landlord therein, in an amount required by its
insurance company to avoid the application of any coinsurance provision. Landlord hereby waives its right of action and recovery against and releases Tenant and Tenant’s Affiliates, shareholders, partners, directors, officers, employees, agents
and representatives (“Tenant’s Representatives”) from any and all liabilities, claims and losses for which they may otherwise be liable to the extent that (i) Landlord is covered therefor by insurance carried or
required to be carried under this Lease and (ii) provided that Landlord is carrying such required insurance, Landlord receives proceeds therefor. Landlord shall secure a waiver of subrogation endorsement from its insurance carrier with respect
to Tenant and Tenant’s Representatives. Landlord also agrees to carry and maintain, throughout the Lease Term, commercial general liability insurance in limits it reasonably deems appropriate (but in no event less than the limits required of
Tenant pursuant to Section 12.2 above). Landlord may elect to carry such other additional insurance or higher limits as it reasonably deems appropriate. Tenant acknowledges that Landlord shall not carry insurance on, and shall not be
responsible for damage to, Tenant’s personal property or any Alterations installed by Tenant (including, without limitation, Tenant’s Work), and that Landlord shall not carry insurance against, or be responsible for any loss suffered by
Tenant due to, interruption of Tenant’s business. 
 ARTICLE XIII 
 SERVICES AND UTILITIES 
 13.1 The Building is at all times subject to the
exclusive control, management and operation of Landlord. Subject to the terms and provisions of this Lease, Landlord has the right with respect to such control, management and operation to: 
 (i) obstruct or close off all or any part of the Property for the purpose of maintenance, repair or construction, provided that Tenant’s use
of or access to the Premises is not unreasonably impaired thereby; 
 (ii) employ all personnel necessary for the operation and
management of the Building, either directly or through an experienced third party property management company and, in connection therewith, Landlord shall maintain adequate personnel at the Building twenty-four (24) hours per day, seven
(7) days per week; 
 (iii) construct other improvements and make alterations, additions, subtractions or re-arrangements,
construct facilities adjoining or proximate to the Building, including underground tunnels and pedestrian walkways and overpasses, provided that Tenant’s use of, normal operations in or access to, the Premises in accordance with the Permitted
Uses is not impaired thereby;

 (iv) do and perform such other acts in and to the Building and, in connection with performing
any maintenance or repair obligations of Landlord, in and to the Premises and to have access thereto, as, in the use of good business judgment, Landlord determines to be advisable for the more efficient and proper operation of the Building and
Premises, provided that Tenant’s use of, normal operations in or access to, the Premises in accordance with the Permitted Uses is not unreasonably impaired thereby; and 
 (v) reasonably control, supervise and regulate the parking areas in such manner as the Landlord determines from time to time. 
 13.2 During the Term, the Landlord shall provide, or cause to be provided to the Premises, the following services and utilities upon the terms and
subject to the conditions set out in this Article XIII and in Exhibit F attached hereto: 
 (i) heating, ventilation and
air conditioning (“HVAC”) for the Premises shall be provided at all times in order to maintain the Environmental Conditions (as hereinafter defined), including maintaining a temperature adequate for normal occupancy in
accordance with the Permitted Uses, including heat rejection equipment capable of handling 2.275 megawatts of Critical Load Power; 
 (ii) water, gas and fuel in amounts no less than the amounts customarily provided by the owners of similarly sized, first-class data centers, as installed in the Building and Premises; 
 (iii) PDUs sufficient to support 2.275 megawatts of Critical Load Power to the Premises (the “Maximum Load Limit”);

 (iv) Landlord-installed, secure conduits that enable Tenant to access connectivity to one or more fiber providers from the
Premises to [*****] POEs within the Building; provided, however, that Tenant may, pursuant to Section 11.3 above, utilize one or more Approved Fiber Providers for the connection of new fiber lines from and through each of the Telecommunications
Duct Banks to the Building and into [*****] POEs; 
 (v) security for the Building in accordance with Article V hereof; and

 (vi) loading dock facilities convenient to the Premises twenty-four (24) hours a day, seven (7) days a week. 

Landlord represents, warrants and covenants to Tenant that, commencing on the Lease Commencement Date and throughout the Lease Term, (I) Critical
Load Power up to the Maximum Load Limit will be available to the Premises, (II) the Premises shall be provided with a dedicated back-up system for such Critical Load Power, including UPS and Engine Generators and (III) all Building infrastructure
shall be operational in accordance with industry standards and procedures for first-class data centers, accounting for, among other things, repairs, scheduled

maintenance and emergency situations. Landlord further represents and warrants that the critical electrical and mechanical systems of each of ACC4 Phase I
and Phase II are designed in a 14N + 2R configuration with 18.2 megawatts of Critical Load Power over the raised floor space, thus 2.275 megawatts of Critical Load Power, with N+2R redundancy, shall be available to the Premises when all
infrastructure is operational as provided herein above. 
 As used herein, “Critical Load Power” shall mean the total
electrical power supplied to the input circuit breakers of the PDUs within the Premises and excluding electrical power needed for any heat rejection or HVAC system, lighting or other common facility systems or services. 
 13.3 Tenant hereby acknowledges that the proper functioning of the Building as a data center requires Tenant to, at all times, maintain a clean
Premises environment. In connection with the foregoing and notwithstanding anything to the contrary contained herein, Tenant shall clean the Premises, including the raised floor surface and subsurface, in accordance with industry standards and
procedures for cleaning first-class, mission critical data center environments; provided, however, all cleaning of subsurface environments (i.e., beneath the raised floor in the Premises) must be approved in advance by Landlord, supervised by
Landlord or Landlord’s agent, and performed in accordance with Landlord’s reasonable rules and regulations for performing such work. Tenant shall be solely responsible for providing, and shall pay directly all janitorial and other charges
relating to, such cleaning services to the Premises. 
 13.4 Tenant shall be solely responsible for the distribution of electrical
power from the load side of each PDU (including the output circuit breakers) within the Premises to the remainder of the Premises and for the installation and related maintenance of equipment and systems required in connection with such
distribution. Tenant shall, in no event, whether by the installation or placement of equipment or improvements or otherwise, interfere with Landlord’s delivery of electrical power to the line side of each PDU (up to and including the output
bus) within the Premises. All charges for, or associated with, any service or utility which is separately measured or submetered to the Premises (including without limitation the Critical Load Power and charges for CRAC usage) shall be billed
directly to Tenant (without any mark-up by Landlord) and paid to Landlord, or, if requested in writing by Landlord (where applicable), paid directly by Tenant to the utility provider. In each case, payment shall be made within thirty (30) days
of Tenant’s receipt of an invoice therefor. Charges for or associated with all other services or utilities which are required to be provided by Landlord under Section 13.2 which are not separately measured shall be included in Operating
Expenses and shall be paid by Tenant each month as provided in Article IV based on Tenant’s Pro Rata Share. Notwithstanding the foregoing, Tenant shall be charged monthly, in advance, for electricity to be consumed to supply the Premises
with heat rejection HVAC for the following month in an amount equal to the estimated monthly charge for Critical Load Power to be used by Tenant for the following month (based on the prior month’s usage) multiplied by [*****] (the
“Monthly Heat Rejection Charge”). The estimated Monthly Heat Rejection Charges will be reconciled with the actual monthly charges for electricity used to supply the Premises with heat rejection HVAC not less frequently than
annually and not more often than monthly. The reconciliation of Monthly Heat Rejection Charges for any particular month shall be added to, or subtracted from, as applicable, the Monthly Heat Rejection Charge for the month following the date of any
such reconciliation. The Monthly Heat Rejection Charge shall be payable by Tenant on the later to occur of: (i) the 

  

 30.

first day of the calendar month immediately following the date on which Tenant receives an invoice from Landlord setting forth the Monthly Heat Rejection
Charge for the following month or (ii) within fifteen (15) Business Days of receipt of such invoice from Landlord setting forth the Monthly Heat Rejection Charge. In the event any electrical utility serving the Premises imposes a
“power factor” surcharge or similar surcharge as a result of Tenant’s use of the Premises, including, without limitation, as a result of the power factor of any of Tenant’s equipment, Landlord shall reasonably determine the
portion of the surcharge allocable to Tenant and invoice Tenant therefor. Tenant shall pay amounts so invoiced within thirty (30) days of receipt of each such invoice, accompanied by reasonable back-up documentation. The Critical Load Power
supplied to the Premises shall be separately metered or submetered. 
 13.5 It is understood and agreed that Landlord shall, prior to
the Lease Commencement Date, engage the services of a professional data center management company (together with its successors and/or assigns, the “Management Company”) to provide certain management services in connection
with the operation of the Building, including, without limitation, on-site facility engineering support services, maintenance and repair required of Landlord under this Lease and other services customary to first class data centers. The initial
Management Company shall be DuPont Fabros Technology, L.P. In addition, DF Technical Services LLC (“DFTS”), an affiliate of Landlord, shall be available to Tenant, on a direct contract basis and pursuant to a separate
agreement at market rates to provide services with respect to the Premises, including, without limitation, tenant deployment services. To the extent that Tenant is not satisfied with the pricing of the services of DFTS, Tenant shall have the right,
subject to Article IX of this Lease, to contract those services directly with a vendor included on Landlord’s list of approved vendors or a vendor otherwise proposed by Tenant and approved by Landlord, which approval shall not be
unreasonably withheld, conditioned or delayed (each an “Approved Vendor”). To the extent the Management Company carries out the duties and obligations of Landlord under this Lease, then all restrictions and obligations
imposed pursuant to this Lease on Landlord shall be deemed to extend to the Management Company, and Landlord shall cause the Management Company to comply with all such restrictions and obligations. 
 13.6 [*****] Tenant will neither utilize more than the Maximum Load Limit nor install any equipment which will exceed or overload the capacity of
any utility, electrical, HVAC, or mechanical facilities in the Premises or Building. Tenant will not bring into the Premises or install any utility, electrical, HVAC, or mechanical facility which Landlord does not approve, such approval not to be
unreasonably withheld, conditioned, or delayed. Notwithstanding the foregoing, provided that Tenant’s plans for configuration of the Premises have been approved by Landlord in accordance with Article IX above, Tenant shall not be
required to obtain Landlord’s approval to bring into the Premises, or install, any computer, network or telecommunications equipment and facilities to be used by Tenant or any Permitted Licensees where the installation of such equipment and/or
facilities is consistent with Tenant’s approved plans. 
 13.7 If any damage is caused to the Building or the Premises by any of
Tenant’s machinery, equipment, objects or things or by overloading by Tenant as described in Section 13.6 above, Tenant will forthwith repair such damage, or, at the option of Landlord, pay Landlord within thirty (30) days after
receipt of written demand accompanied by reasonable back-up documentation and invoices, as Additional Rent, the cost of repairing such damage plus a sum equal to five percent (5%) of such cost representing Landlord’s overhead and
administrative costs.

 13.8 Landlord acknowledges that Tenant’s business operations require the continuous
provision of electrical power, HVAC, and monitoring services in accordance with the standards, and in the amounts, specified herein (collectively, the “Critical Services”). Except as expressly set forth in this Lease, neither
Landlord nor Tenant will take any action which would interrupt the Critical Services without the prior written consent of the other party, which consent may be granted or withheld in such party’s sole and absolute discretion. Landlord will use
diligent and best efforts not to interfere with or interrupt Tenant’s operations within the Premises and will take immediate action to remedy any circumstances in which Landlord or any Landlord Party interferes with Tenant’s Critical
Services (except to the extent expressly permitted by this Lease). In the event of any interruption of Critical Services (a “Service Interruption”), Tenant shall, promptly upon becoming aware thereof, notify Landlord’s
Emergency Contacts in accordance with Article V hereof; such notice shall state with reasonable detail the nature of the interruption in question (each such notice, an “Interruption Notice”). Upon receipt of notice of
any Interruption Notice or upon Landlord or the Management Company otherwise gaining knowledge of any Service Interruption, Landlord shall immediately undertake diligent efforts, consistent with first class data center providers, to cause the
Service Interruption to be immediately remedied. Landlord shall maintain periodic contact with Tenant until the Service Interruption is resolved. [*****] 
 13.9 [*****] 
 ARTICLE XIV 
 LIABILITY OF LANDLORD 
 14.1 Except as otherwise set forth in this Lease,
Landlord and Landlord’s Representatives shall not be liable to Tenant, any Agent or any other person or entity for any and all damage, injury, loss or claim based on or arising out of any cause whatsoever, including without limitation the
following: repair to any portion of the Premises (except for Landlord’s maintenance, repair and replacement obligations as set forth in Article VIII above); interruption in the use of the Premises or any equipment therein (except for
Landlord’s obligations as set forth in Article XIII above); any accident or damage resulting from any use or operation (by Landlord, Tenant or any other person or entity) of heating, cooling, electrical, sewage or plumbing equipment or
apparatus (except for Landlord’s obligations as set forth in Article XIII above); termination of this Lease by reason of damage to the Premises or the Building; any fire, robbery, theft, vandalism, mysterious disappearance or any other
casualty; actions of any other tenant of the Building or of any other person or entity; failure or inability to furnish any service specified in this Lease (except for Landlord’s obligations to provide services and utilities as provided in
Article XIII); and leakage in any part of the Premises or the Building from water, rain, ice or snow that may leak into, or flow from, any part of the Premises or the Building, or from drains, pipes or plumbing fixtures in the Premises or the
Building. If any condition exists which may be the basis of a claim of constructive eviction, then Tenant shall give Landlord written notice thereof and a reasonable opportunity to correct such condition, and in the interim 

  

 32. 

			
		  	CONFIDENTIAL MATERIAL HAS BEEN OMITTED AND
		  	FILED SEPARATELY WITH THE SECURITIES AND
		  	EXCHANGE COMMISSION. BOXES AND ASTERIXES
		  	DENOTE SUCH OMISSION

  

 
Tenant shall not claim that it has been constructively evicted or is entitled to a rent abatement. Any property placed by Tenant or any Agent in or about the
Premises or the Building shall be at the sole risk of Tenant, and Landlord shall not in any manner be held responsible therefor. Any person receiving an article delivered for Tenant shall be acting as Tenant’s agent for such purpose and not as
Landlord’s agent. For purposes of this Article XIV, the term “Building” shall be deemed to include the Land. Notwithstanding the foregoing provisions of this Section 14.1, and subject to Section 12.2(b) above, Landlord shall
not be released from liability (a) to Tenant for any physical injury to any natural person or damage to Tenant’s personal property caused by the negligence or willful misconduct of Landlord or Landlord’s Representatives, provided that
for damage to personal property, Landlord shall only be liable to the extent that such damage is not covered by insurance either carried by Tenant or required by this Lease to be carried by Tenant or (b) to the extent resulting from the breach
or default by Landlord of its representations, warranties, covenants, duties and/or obligations under this Lease; provided, however, that neither Landlord nor any of Landlord’s Representatives (nor any past, present or future board member,
partner, trustee, director, member, officer, employee, agent, representative or advisor of any of them) shall under any circumstances under this Lease (including, without limitation, with respect to its reimbursement and indemnity obligations set
forth in Section 14.2(b) below) be liable for: (i) any exemplary or punitive damages or (ii) any consequential or indirect damages (or for any interruption of or loss to business) to the extent that (A) Landlord is not covered
therefor by insurance carried, or required to be carried under this Lease, and (B) provided that Landlord is carrying such required insurance, Landlord receives proceeds therefor, all in connection with or relating to this Lease. 
 14.2 (a) Except to the extent caused by the negligence or willful misconduct of Landlord or its agents, and subject to Section 12.3 above,
Tenant shall reimburse Landlord, its employees and agents for (as additional rent), and shall indemnify, defend upon request and hold them harmless from and against all reasonable costs, damages, claims, liabilities, expenses (including reasonable
attorneys’ fees), losses, penalties and court costs (collectively, “Costs”) suffered by or claimed against them, directly or indirectly, based on or arising out of, in whole or in part, (i) use and occupancy of the
Premises or the business conducted therein, (ii) any negligent or willful act or omission of Tenant or any Agent, (iii) any breach of Tenant’s obligations under this Lease, including failure to comply with Laws or surrender the
Premises upon the expiration or earlier termination of the Lease Term, or (iv) any entry by Tenant or any Agent upon the Land prior to the Lease Commencement Date in violation of the terms and provisions of this Lease. In no event, however,
shall Tenant, Guarantor (as hereinafter defined), or any of Tenant’s Representatives (nor any past, present or future board member, partner, trustee, director, member, officer, employee, agent, representative or advisor of any of them), under
any circumstances under this Section 14.2(a) or elsewhere under this Lease, be liable for: (I) any exemplary or punitive damages or (II) any consequential or indirect damages (or for any interruption of or loss to business) to the extent
that (A) Tenant is not covered therefor by insurance carried, or required to be carried under this Lease, and (B) provided that Tenant is carrying such required insurance, Tenant receives proceeds therefor. 
 (b) Except to the extent caused by the negligence or willful misconduct of Tenant or an Agent of Tenant, and subject to Section 12.2(b)
above, Landlord shall reimburse Tenant and shall indemnify and hold Tenant harmless from and against all Costs suffered or

claimed against Tenant as a result of: (i) Landlord’s use or control of the common areas of the Building and the Building Structure and Systems,
(ii) any negligent or willful act or omission of Landlord, its agents, employees or contractors, or (iii) any breach of Landlord’s obligations under this Lease. 
 14.3 No landlord hereunder shall be liable for any obligation or liability based on or arising out of any event or condition occurring during the
period that such landlord was not the owner of the Property. Within five (5) days after request, Tenant shall attorn to any transferee landlord and execute, acknowledge and deliver any document submitted to Tenant confirming such attornment,
provided such transferee assumes the obligations of Landlord hereunder which accrue from and after the date of the transfer. 
 14.4
Except as otherwise expressly provided herein, Tenant shall not have the right to set off or deduct any amount allegedly owed to Tenant pursuant to any claim against Landlord from any rent or other sum payable to Landlord. Tenant’s sole
remedy for recovering upon such claim shall be to institute an independent action against Landlord, which action shall not be consolidated with any action of Landlord; provided, however, that the foregoing shall not prohibit Tenant from asserting a
compulsory counterclaim in any proceeding instituted by Landlord against the Tenant that is required to be brought by applicable statute and will be deemed forever waived if not then asserted by Tenant. 
 14.5 If Tenant or any Agent is awarded a money judgment against Landlord, then recourse for satisfaction of such judgment shall be limited to
execution against Landlord’s estate and interest in the Property, which shall be deemed to include proceeds actually received by Landlord from any sale of the Building (net of all expenses of sale), insurance or condemnation proceeds (subject
to the rights of any Mortgagees), and rental income from the Building (net of all expenses). No other asset of Landlord, and no asset of any of Landlord’s Representatives (or any past, present or future board member, partner, director, member,
officer, trustee, employee, agent, representative or advisor of any of them (each, an “officer”)) or any other person or entity, shall be available to satisfy or be subject to any such judgment. No such Landlord’s Representative,
officer or other person or entity shall be held to have personal liability for satisfaction of any claim or judgment whatsoever under this Lease. 
 ARTICLE XV 
 RULES AND REGULATIONS 
 15.1 Tenant agrees to comply with and observe the rules and regulations pertaining to the use and occupancy of the Premises or the Building set forth in Exhibit E attached hereto, together with all
reasonable amendments thereto as may be promulgated in writing hereafter by Landlord in accordance with the terms and provisions of this Section 15.1 (the “Rules and Regulations”). Tenant’s failure to keep and
observe said Rules and Regulations after notice and opportunity to cure as set forth in Section 18.1(b) hereof shall constitute a material breach of the terms of this Lease. Landlord reserves the right from time to time to reasonably amend or
supplement said Rules and Regulations and to adopt and promulgate additional reasonable Rules and Regulations applicable to the Premises and the Building, provided, that any such 

  

 34. 

			
		  	CONFIDENTIAL MATERIAL HAS BEEN OMITTED AND
		  	FILED SEPARATELY WITH THE SECURITIES AND
		  	EXCHANGE COMMISSION. BOXES AND ASTERIXES
		  	DENOTE SUCH OMISSION

  

 
amendments, supplements or additional Rules and Regulations shall not materially reduce Tenant’s rights under this Lease or materially interfere with
Tenant’s use of the Premises. Upon receipt thereof, Tenant agrees thereupon to comply with and observe any such additional, amended or supplemental Rules and Regulations promulgated by Landlord in accordance with this Section 15.1. In the
event of any inconsistency between this Lease and the Rules and Regulations, the provisions of this Lease shall prevail and control. Any violation of the Rules and Regulations by any individual that is not under Tenant’s control shall not
constitute a default under this Lease. Landlord shall apply and enforce the Rules and Regulations in a uniform and non-discriminatory manner. 
 ARTICLE XVI 
 DAMAGE OR DESTRUCTION 
 16.1 If the Premises or the Building are totally or partially damaged or destroyed thereby rendering the Premises totally or partially inaccessible or unusable, then Landlord shall diligently repair and restore
the Premises and the Building to substantially the same condition they were in prior to such damage or destruction; provided, however, that if in Landlord’s reasonable judgment such repair and restoration cannot be completed within one hundred
eighty (180) days after the occurrence of such damage or destruction (taking into account the time needed for effecting a satisfactory settlement with any insurance company involved, removal of debris, preparation of plans and issuance of all
required governmental permits), then Landlord shall have the right to terminate this Lease by giving written notice of termination within forty-five (45) days after the occurrence of such damage or destruction. If this Lease is terminated
pursuant to this Article XVI, then rent shall be apportioned as of the date of the happening of the damage or destruction (based on the portion of the Premises and Critical Load Power which is usable or used after such damage or destruction) and
paid to the earlier of the date of termination or the date Tenant completely vacates and abandons the Premises on account of such damage. If this Lease is not terminated as a result of such damage or destruction, then until such repair and
restoration of the Premises are substantially complete, as of the date of the happening of the damage or destruction, Tenant shall be required to pay rent only for the portion of the Premises and Critical Load Power that is usable while such repair
and restoration are being made; provided, however, that if such damage or destruction was caused by the grossly negligent or willful misconduct of Tenant or any Agent, then Tenant shall not be entitled to any such rent reduction. After receipt of
all insurance proceeds (including proceeds of insurance maintained by Tenant), Landlord shall diligently proceed with, and bear the expenses of, such repair and restoration of the Premises and the Building as aforesaid; provided, however, that
(a) if such damage or destruction was caused by the grossly negligent or willful misconduct of Tenant or any Agent, then Tenant shall pay Landlord’s deductible and the amount by which such expenses exceed the insurance proceeds, if any,
actually received by Landlord on account of such damage or destruction (or, if Landlord fails to maintain the insurance required by Section 12.3, that Landlord would have received to the extent Landlord maintained such insurance required by
Section 12.3), (b) Tenant shall pay the amount by which the cost of restoring any item which Landlord is required to restore and Tenant is required to insure exceeds the insurance proceeds received with respect thereto, and
(c) Landlord shall not be required to repair or restore any tenant improvements installed by Tenant in the Premises (except to the extent Landlord receives

proceeds therefor from Tenant’s insurance), any Alterations (excluding Landlord’s Work) or any of Tenant’s contents within the Premises
(including, without limitation, Tenant’s trade fixtures, decorations, furnishings, equipment, facilities or personal property, but excluding PDUs, CRACs, HVAC cooling support equipment, fire detection and alarm and fire suppression systems and
equipment and any other equipment, facilities or other property of Landlord comprising the Building Structure and Systems and located within the Premises, which shall be Landlord’s responsibility). Notwithstanding anything herein to the
contrary, Landlord shall have the right to terminate this Lease if (1) insurance proceeds plus deductibles are insufficient to pay the full cost of such repair and restoration so long as Landlord maintains the insurance required by
Section 12.3 above, (2) the holder of any Mortgage fails or refuses to make such insurance proceeds available for such repair and restoration, (3) zoning or other applicable Laws or regulations do not permit such repair and
restoration, or (4) the damage to the Building exceeds thirty five percent (35%) of the replacement value of the Building; provided, however, that Landlord shall be entitled to terminate this Lease under subsections (1), (2), (3) and
(4) above only if Landlord simultaneously terminates the leases (or applicable portions thereof) of all other tenants leasing Pods that are in a substantially similar condition to the Premises after such damage or destruction. 
 16.2 If, within forty five (45) days after the occurrence of the damage or destruction described in Section 16.1 above, Landlord
determines in its sole but reasonable judgment that the repairs and restoration cannot be substantially completed within one hundred eighty (180) days after the date of such damage or destruction, and Landlord does not elect to terminate this
Lease pursuant to this Article XVI, then Landlord shall notify Tenant of such determination within such forty-five (45) day period. For a period continuing through the later of the thirtieth (30th) day after the occurrence of the damage or
destruction or the tenth (10th) day after receipt of such notice, Tenant shall have the right to terminate this Lease by providing written notice to Landlord (which date of such termination shall be not more than thirty (30) days after the
date of Tenant’s notice to Landlord). [*****] 
 ARTICLE XVII 
 CONDEMNATION 
 17.1 If one third or more of the Premises, or the use or
occupancy thereof, or any portion of the Building required for the reasonable and proper use of the Premises, shall be taken or condemned by any governmental or quasi governmental authority for any public or quasi public use or purpose or sold under
threat of such a taking or condemnation (collectively, “condemned”), then this Lease shall terminate on the day prior to the date title thereto vests in such authority and rent shall be apportioned as of such date. If less
than one third of the Premises or occupancy thereof or portions of the Building not required for the proper use of the Building, is condemned, then this Lease shall continue in full force and effect as to the part of the Premises not so condemned,
except that as of the date title vests in such authority Tenant shall not be required to pay rent with respect to the part of the Premises so condemned. Landlord shall notify Tenant of any condemnation contemplated by this Section 17.1 promptly
after Landlord receives notice thereof. Within ten (10) days after receipt of such notice, Tenant shall have the right to terminate this Lease with respect to the remainder of the Premises not so condemned as 

  

 36.

of the date title vests in such authority, but only if such condemnation renders said remainder of the Premises totally unusable for their intended purpose.
Notwithstanding anything herein to the contrary, if twenty five percent (25%) or more of the Land or the Building is condemned, then whether or not any portion of the Premises is condemned, Landlord shall have the right to terminate this Lease
as of the date title vests in such authority, provided, that, as a condition to such right, Landlord must simultaneously terminate the leases (or applicable portions thereof) of all other tenants in the Building leasing Pods that are affected in a
substantially similar manner as the premises by such condemnation. 
 17.2 All awards, damages and other compensation paid by the
condemning authority on account of such taking or condemnation (or sale under threat of such a taking) shall belong to Landlord, and Tenant hereby assigns to Landlord all rights to such awards, damages and compensation. Tenant agrees not to make any
claim against Landlord or the condemning authority for any portion of such award or compensation attributable to damages to the Premises, the value of the unexpired term of this Lease, the loss of profits or goodwill, leasehold improvements or
severance damages. Nothing contained herein, however, shall prevent Tenant from pursuing a separate claim against the condemning authority for the value of furnishings, equipment and trade fixtures installed in the Premises at Tenant’s expense
and for relocation expenses, provided that such claim does not in any way diminish the award or compensation payable to or recoverable by Landlord in connection with such taking or condemnation. 
 ARTICLE XVIII 
 DEFAULT

 18.1 Each of the following shall constitute an “Event of Default” by Tenant under this Lease:

 (a) Tenant’s failure to make when due any payment of Base Rent, Additional Rent or other sum, which failure shall continue for
a period of five (5) days after receipt by Tenant of written notice thereof, provided, however, that landlord shall not be required to give Tenant more than two (2) such written notices during any Lease Year during the Lease Term;

 (b) Tenant’s failure to perform or observe any covenant or condition of this Lease not otherwise specifically described in
this Section 18.1, which failure shall continue for a period of thirty (30) days after receipt by Tenant of written notice thereof; provided, however, that if such cure cannot reasonably be effected within such thirty (30) day period
and Tenant begins such cure promptly within such thirty (30) day period and is pursuing such cure in good faith and with diligence and continuity during such thirty (30) day period, then, except in the event of an emergency, Tenant shall
have such additional time as is reasonably necessary to effect such cure; 
 (c) an Event of Bankruptcy as specified in Article XIX
hereof; 
 (d) Tenant’s dissolution or liquidation; 
 (e) any Environmental Default as specified in Section 6.3 hereof; 
  

 37.

		  	DENOTE SUCH OMISSION

  

 (f) Tenant’s failure to execute, acknowledge and deliver the written statement required
by Section 24.4 hereof after receipt by Tenant of written notice thereof and a ten (10) day cure period; 
 (g) excluding
any sublease or assignment requiring Landlord’s consent but that Tenant believed in good faith was permitted under Section 7.2(b) above, any sublease, assignment or mortgage not permitted by Article VII hereof; or 
 (h) the occurrence of [*****] Prohibited Spikes [*****]. 
 18.2 If there shall be an Event of Default (even if prior to the Lease Commencement Date), then the provisions of this Section 18.2 shall apply. Landlord shall have the right, at its sole option, to
terminate this Lease upon delivery of written notice to Tenant. In addition, with or without terminating this Lease, Landlord may re-enter, terminate Tenant’s right of possession and take possession of, the Premises. The provisions of this
Article XVIII shall operate as a notice to quit, and Tenant hereby waives any other notice to quit or notice of Landlord’s intention to re-enter the Premises. If necessary, Landlord may proceed to recover possession of the Premises under
applicable Laws, or by such other proceedings, including re-entry and possession, as may be applicable. If Landlord elects to terminate this Lease and/or elects to terminate Tenant’s right of possession, everything contained in this Lease on
the part of Landlord to be done and performed shall cease without prejudice, however, to Tenant’s liability for all Base Rent, additional rent and other sums specified herein. Whether or not this Lease and/or Tenant’s right of possession
is terminated, Landlord shall have the right, at its sole option, to terminate any renewal or expansion right contained in this Lease and to grant or withhold any consent or approval pursuant to this Lease in its sole and absolute discretion. If an
Event of Default has occurred under this Lease and Tenant has vacated the Premises, and if Landlord has terminated this Lease as a result of such Event of Default, then Landlord shall thereafter use reasonable efforts to relet the Premises;
provided, however, that Tenant understands and agrees that Landlord’s main priority will be the leasing of other space in the Building (and not then leased by Landlord), and the reletting of the Premises will be of lower priority. Tenant hereby
expressly waives, for itself and all persons claiming by, through or under it, any right of redemption, re-entry or restoration of the operation of this Lease under any present or future Law, including without limitation any such right which Tenant
would otherwise have in case Tenant shall be dispossessed for any cause, or in case Landlord shall obtain possession of the Premises as herein provided. Landlord may relet the Premises or any part thereof, alone or together with other premises, for
such term(s) (which may extend beyond the date on which the Lease Term would have expired but for Tenant’s default) and on such terms and conditions (which may include any concessions or allowances granted by Landlord) as Landlord, in its sole
and absolute but reasonable discretion, may determine, but Landlord shall not be liable for, nor shall Tenant’s obligations hereunder be diminished by reason of, any failure by Landlord to relet all or any portion of the Premises or to collect
any rent due upon such reletting. Whether or not this Lease is terminated or any suit is instituted, Tenant shall be liable for any Base Rent, additional rent, damages or other sum which may be due or sustained prior to such Event of Default, and
for all costs, fees and expenses (including, but not limited to, attorneys’ fees and costs, brokerage fees (to the extent proportionately allocable to the remaining Lease Term), expenses incurred in placing the Premises in first-class rentable
condition, advertising expenses,

and any concessions or allowances granted by Landlord) incurred by Landlord in pursuit of its remedies hereunder and/or in recovering possession of the
Premises and renting the Premises to others from time to time until the date the Lease Term would have expired but for Tenant’s default. Tenant also shall be liable for additional damages which at Landlord’s election shall be either:
(a) an amount equal to the Base Rent and additional rent due or which would have become due from the date of Tenant’s default through the remainder of the Lease Term, less the amount of rental, if any, which Landlord receives during such
period from others to whom the Premises may be rented (other than any additional rent received by Landlord as a result of any failure of such other person to perform any of its obligations to Landlord), which amount shall be computed and payable in
monthly installments, in advance, on the first day of each calendar month following Tenant’s default and continuing until the date on which the Lease Term would have expired but for Tenant’s default, it being understood that separate suits
may be brought from time to time to collect any such damages for any month(s) (and any such separate suit shall not in any manner prejudice the right of Landlord to collect any damages for any subsequent month(s)), or Landlord may defer initiating
any such suit until after the expiration of the Lease Term (in which event such deferral shall not be construed as a waiver of Landlord’s rights as set forth herein and Landlord’s cause of action shall be deemed not to have accrued until
the expiration of the Lease Term); or (b) an amount equal to the difference between (i) all Base Rent, additional rent and other sums due or which would be due and payable under this Lease as of the date of Tenant’s default through
the end of the scheduled Lease Term, and (ii) the fair market value rental of the Premises over the same period (net of all expenses (including attorneys’ fees) and all vacancy periods reasonably projected by Landlord to be incurred in
connection with the reletting of the Premises), as determined by Landlord in its sole and absolute discretion, which difference shall be discounted at a rate equal to one (1) whole percentage point above the discount rate in effect on the date
of payment at the Federal Reserve Bank nearest the Building, and which resulting amount shall be payable to Landlord in a lump sum on demand, it being understood that upon payment of such liquidated and agreed final damages, Tenant shall be released
from further liability under this Lease with respect to the period after the date of such payment, and that Landlord may bring suit to collect any such damages at any time after an Event of Default shall have occurred. Tenant shall pay all expenses
(including attorneys’ fees) incurred by Landlord in connection with or as a result of any Event of Default whether or not a suit is instituted. The provisions contained in this Section 18.2 shall be in addition to, and shall not prevent
the enforcement of, any claim Landlord may have against Tenant for anticipatory breach of this Lease (including, without limitation, the right of injunction and the right to invoke any remedy allowed at law or in equity as if reentry, summary
proceedings and other remedies were not provided for herein). Nothing herein shall be construed to affect or prejudice Landlord’s right to prove, and claim in full, unpaid rent accrued prior to termination of this Lease. If Landlord is
entitled, or Tenant is required, pursuant to any provision hereof to take any action upon the termination of the Lease Term, then Landlord shall be entitled, and Tenant shall be required, to take such action also upon the termination of
Tenant’s right of possession. 
 18.3 All rights and remedies of Landlord set forth herein are cumulative and in addition to all
other rights and remedies available to Landlord at law or in equity including those available for anticipatory breach. The exercise by Landlord of any such right or remedy shall not prevent the concurrent or subsequent exercise of any other right or
remedy. No delay in the enforcement or exercise of any right or remedy by Landlord or Tenant shall constitute a waiver

of any default by the other party hereunder or of such party’s rights or remedies in connection therewith. Neither party hereto shall be deemed to have
waived any default by the other party hereunder unless such waiver is set forth in a written instrument signed by the party against whom such waiver is asserted. If either party waives in writing any default by Tenant, such waiver shall not be
construed as a waiver of any covenant, condition or agreement set forth in this Lease except as to specific circumstances described in such written waiver. 
 18.4 If Landlord shall institute proceedings against Tenant and a compromise or settlement thereof shall be made, the same shall not constitute a waiver of default or of any other covenant, condition or
agreement set forth herein, nor of any of Landlord’s rights hereunder, except to the extent agreed by Landlord in writing in connection with such compromise or settlement. Neither the payment by Tenant of a lesser amount than the installments
of Base Rent, Additional Rent or of any sums due hereunder nor any endorsement or statement on any check or letter accompanying a check for payment of rent or other sums payable hereunder shall be deemed an accord and satisfaction, and Landlord may
accept such check or payment without prejudice to Landlord’s right to recover the balance of such rent or other sums or to pursue any other remedy available to Landlord. Notwithstanding any request or designation by Tenant, Landlord may apply
any payment received from Tenant to any payment then due. No re-entry by Landlord, and no acceptance by Landlord of keys from Tenant, shall be considered an acceptance of a surrender of this Lease. 
 18.5 If Tenant defaults in the making of any payment or in the doing of any act herein required to be made or done by Tenant, then Landlord may,
but shall not be required to, make such payment or do such act after Landlord delivers written notice to Tenant. If Landlord elects to make such payment or do such act, all costs incurred by Landlord, plus interest thereon at the rate per annum
which is three percent (3%) higher than the Prime Rate published in the Money Section of the Wall Street Journal (the “Prime Rate”) from the date paid by Landlord to the date of payment thereof by Tenant, shall
constitute Additional Rent hereunder and shall be immediately paid by Tenant to Landlord; provided, however, that nothing contained herein shall be construed as permitting Landlord to charge or receive interest in excess of the maximum rate then
allowed by law. The taking of such action by Landlord shall not be considered as a cure of such default by Tenant or prevent Landlord from pursuing any remedy it is otherwise entitled to in connection with such default. 
 18.6 If Tenant fails, on more than two (2) occasions in any Lease Year during the Lease Term, to make any payment of Base Rent on or before
the date that is five (5) Business Days after such payment is due and payable, Tenant shall pay to Landlord a late charge of two percent (2%) of the amount of such payment of Base Rent. If Tenant fails to make any payment of Base Rent or
Additional Rent on or before the date such payment is due and payable, such payment shall bear interest at the rate per annum which is three percent (3%) higher than the Prime Rate from the date such payment became due to the date of payment
thereof by Tenant; provided, however, that nothing contained herein shall be construed as permitting Landlord to charge or receive interest in excess of the maximum rate then allowed by law. Such interest shall constitute Additional Rent due and
payable hereunder with the next installment of Base Rent due hereunder.

 ARTICLE XIX 
 BANKRUPTCY 
 19.1 An “Event of Bankruptcy” is the occurrence with
respect to any of Tenant, a Guarantor or any other person liable for Tenant’s obligations hereunder (including, without limitation, any general partner of Tenant (a “General Partner”)) of any of the following:
(a) such person becoming insolvent, as that term is defined in Title 11 of the United States Code (the “Bankruptcy Code”) or under the insolvency laws of any state (the “Insolvency Laws”);
(b) appointment of a receiver or custodian for any property of such person, or the institution of a foreclosure or attachment action upon any property of such person; (c) filing by such person of a voluntary petition under the provisions
of the Bankruptcy Code or Insolvency Laws; (d) filing of an involuntary petition against such person as the subject debtor under the Bankruptcy Code or Insolvency Laws, which either (1) is not dismissed within sixty (60) days after
filing, or (2) results in the issuance of an order for relief against the debtor; (e) such person making or consenting to an assignment for the benefit of creditors or a composition of creditors; or (f) an admission by Tenant or
Guarantor of its inability to pay debts as they become due. At any time (but in no event more than one (1) time during any calendar year unless Landlord reasonably and in good faith believes that a substantial change in Tenant’s financial
condition shall have occurred) upon not less than ten (10) days’ prior written notice, Tenant shall submit such information concerning the financial condition of any such person as Landlord may reasonably request. Tenant warrants that all
such information heretofore and hereafter submitted is and shall be correct and complete. 
 19.2 Upon occurrence of an Event of
Bankruptcy, Landlord shall have all rights and remedies available pursuant to Article XVIII above; provided, however, that while a case (the “Case”) in which Tenant is the subject debtor under the Bankruptcy Code is pending,
Landlord’s right to terminate this Lease shall be subject, to the extent required by the Bankruptcy Code, to any rights of Tenant or its trustee in bankruptcy (collectively, “Trustee”) to assume or assume and assign this
Lease pursuant to the Bankruptcy Code. After the commencement of a Case: (i) Trustee shall perform all post-petition obligations of Tenant under this Lease; and (ii) if Landlord is entitled to damages (including, without limitation, unpaid
rent) pursuant to the terms of this Lease, then all such damages shall be entitled to administrative expense priority pursuant to the Bankruptcy Code. Any person or entity to which this Lease is assigned pursuant to the Bankruptcy Code shall be
deemed without further act or deed to have assumed all of the obligations arising under this Lease on and after the date of assignment, and any such assignee shall upon request execute and deliver to Landlord an instrument confirming such
assumption. Trustee shall not have the right to assume or assume and assign this Lease unless Trustee promptly (a) cures all defaults under this Lease, (b) compensates Landlord for damages incurred as a result of such defaults,
(c) provides adequate assurance of future performance on the part of Trustee as debtor in possession or Trustee’s assignee, and (d) complies with all other requirements of the Bankruptcy Code. If Trustee desires to assume and assign
this Lease to any person who shall have made a bona fide offer, then Trustee shall give Landlord written notice of such proposed assignment (which notice shall set forth the name and address of such person, all of the terms and conditions of such
offer, and the adequate assurance to be provided Landlord to assure such person’s future performance under this Lease) no later than fifteen (15) days after

receipt by Trustee of such offer, but in no event later than thirty (30) days prior to the date Trustee shall make application to the appropriate court
for authority and approval to enter into such assignment and assumption, and Landlord shall thereupon have the prior right and option, to be exercised by notice to Trustee given at any time prior to the effective date of such proposed assignment, to
accept (or to cause Landlord’s designee to accept) an assignment of this Lease upon the same terms and conditions and for the same consideration, if any, as the bona fide offer made by such person, less any brokerage commissions which may be
payable out of the consideration to be paid by such person for the assignment of this Lease. If Trustee fails to assume or assume and assign this Lease in accordance with the requirements of the Bankruptcy Code within sixty (60) days after the
initiation of the Case (or such other period as may be provided by the Bankruptcy Code or allowed by the United States Bankruptcy Court for same), then Trustee shall be deemed to have rejected this Lease. If this Lease is rejected or deemed
rejected, then Landlord shall have all rights and remedies available to it pursuant to Article XVIII above. 
 ARTICLE XX 

SUBORDINATION MORTGAGES 
 20.1
This Lease is subject and subordinate to the lien, provisions, operation and effect of all mortgages, deeds of trust, ground leases or other security instruments which may now or hereafter encumber any portion of the Building or the Land
(collectively, “Mortgages”), to all funds and indebtedness intended to be secured thereby, and to all renewals, extensions, modifications, recastings or refinancings thereof. Said subordination and the provisions of this
Section shall be self operative and no further instrument of subordination shall be required by the holder of any Mortgage. The holder of any Mortgage to which this Lease is subordinate shall have the right (subject to any required approval of the
holders of any superior Mortgage) at any time to declare this Lease to be superior to the lien, provisions, operation and effect of such Mortgage. 
 20.2 Tenant shall, at Landlord’s request, promptly execute any requisite or appropriate document confirming such subordination. Tenant waives the provisions of any statute or rule of law now or hereafter in effect which may give
or purport to give Tenant any right to terminate or otherwise adversely affect this Lease and Tenant’s obligations hereunder in the event any foreclosure proceeding is prosecuted or completed or in the event the Building, the Land or
Landlord’s interest therein is transferred by foreclosure, by deed in lieu of foreclosure or otherwise. At the request of any transferee and assumption of Landlord’s obligations as required hereby, Tenant shall attorn to such transferee
and shall recognize such transferee as the landlord under this Lease. Within ten (10) days after the request of such transferee, Tenant shall execute acknowledge and deliver any requisite or appropriate document submitted to Tenant confirming
such attornment. 
 20.3 Notwithstanding anything to the contrary contained herein, the effectiveness of any subordination by Tenant
to any Mortgage as provided herein above shall be subject to the condition that Landlord obtain from the holder of any such Mortgage a non-disturbance agreement, in form reasonably acceptable to Tenant, that provides: (a) so long as Tenant is
not in

		  	FILED SEPARATELY WITH THE SECURITIES AND

		  	DENOTE SUCH OMISSION

  

 
default under this Lease beyond any applicable notice and cure period and (b) Tenant agrees to attorn to the holder of any such Mortgage or to any
transferee in connection with any foreclosure, or sale or transfer in lieu thereof, and recognize such party as landlord under this Lease, as provided in Section 20.2 above, then, in the event of any foreclosure, or sale or transfer in lieu
thereof, this Lease shall remain in full force and effect and Tenant’s use and possession of the Premises as provided herein shall not be disturbed. Landlord represents to Tenant that, as of the Effective Date, KeyBank National Association
(“Lender”) has made a loan to Landlord that is secured by the lien of a Mortgage encumbering the Property (the “Existing Mortgage”) and that no Mortgage other than the Existing Mortgage is a lien on
the Property. Prior to or concurrent with the Effective Date, Landlord shall obtain from Lender a subordination, non-disturbance and attornment agreement (a “SNDA”) in a form set forth on Exhibit G attached hereto and
made a part hereof. Landlord acknowledges and agrees that, unless waived by Tenant in its sole and absolute discretion, the effectiveness of this Lease is conditioned upon the execution and delivery by Lender of a SNDA in the form attached hereto as
Exhibit G within thirty (30) days after the Effective Date. [*****] For avoidance of doubt, Landlord and Tenant acknowledge and agree that, upon full execution and delivery of such SNDA, such SNDA shall be promptly recorded among the
land records of Loudoun County, Virginia. Furthermore, Landlord shall secure for Tenant a SNDA (recognizing Tenant’s rights under this Lease) from the holder of each Mortgage hereafter encumbering the Building and/or the Land on such
holder’s standard form nondisturbance agreement, subject to Tenant’s reasonable approval. 
 ARTICLE XXI 
 HOLDING OVER 
 21.1 If Tenant
(or anyone claiming through Tenant) does not immediately surrender the Premises or any portion thereof upon the expiration or earlier termination of the Lease Term, then, unless otherwise agreed to by the parties hereto in writing for the first six
months of such holdover period, the rent payable by Tenant hereunder shall be increased to equal one hundred fifty percent (150%) of the Base Rent, plus Additional Rent and other sums that would have been payable pursuant to the provisions of
this Lease if the Lease Term had continued during such holdover period. If such holdover period is longer than six (6) months, commencing on the first day of the seventh month of the holdover period and for each month of the holdover period
thereafter, the rent payable by Tenant shall be increased to one hundred seventy-five percent (175%) of the Base Rent, additional rent and other sums that would have been payable pursuant to the provisions of this Lease if the Lease Term had
continued during such holdover period. Such rent shall be computed by Landlord and paid by Tenant on a monthly basis and shall be payable on the first day of such holdover period and the first day of each calendar month thereafter during such
holdover period until the Premises have been vacated. Notwithstanding any other provision of this Lease, Landlord’s acceptance of such rent shall not in any manner adversely affect Landlord’s other rights and remedies, including
Landlord’s right to evict Tenant and to recover all damages. Any such holdover shall be deemed to be a tenancy at sufferance. In no event shall any holdover be deemed a permitted extension or renewal of the Lease Term, and nothing contained
herein shall be construed to constitute Landlord’s consent to any holdover or to give Tenant any right with respect thereto.

 ARTICLE XXII 
 COVENANTS OF LANDLORD 
 22.1 Landlord covenants that it has the right to enter into this Lease
for the term aforesaid, and that so long as Tenant is not in default (beyond the expiration of any applicable notice and cure period) under this Lease, then, subject to the provisions of this Lease, Tenant shall during the Lease Term, peaceably and
quietly occupy and enjoy the full possession of the Premises without hindrance by Landlord, its employees or agents. Tenant acknowledges and agrees that its leasehold estate in and to the Premises vests on the date this Lease is executed,
notwithstanding that the Lease Term will not commence until a future date. 
 ARTICLE XXIII 
 PARKING 
 23.1 During the Lease
Term, Landlord shall maintain no less than one hundred fifty (150) parking spaces for parking in the surface parking areas located adjacent to the Building available on a non-exclusive, unassigned, first-come, first-served basis. Landlord
covenants that, throughout the Lease Term, Landlord will maintain on the Land, at a minimum, the number of parking spaces required by applicable Law. 
 23.2 It is understood and agreed that Landlord does not assume any responsibility for, and shall not be held liable for, any damage or loss to any automobiles parked in the parking areas or to any personal
property located therein, or for any injury sustained by any person in or about the parking areas, except, subject to the insurance requirements and the waiver of subrogation provision set forth in Section 12.2(b) above, for any physical injury
to any natural person or damage to Tenant’s personal property caused by the negligence or willful misconduct of Landlord or Landlord’s Representatives. 
 ARTICLE XXIV 
 GENERAL PROVISIONS 
 24.1 Tenant acknowledges that neither Landlord nor any broker, agent or employee of Landlord has made any representations or promises with respect
to the Premises or the Building except as herein expressly set forth, and no rights, privileges, easements or licenses are being acquired by Tenant except as herein expressly set forth. 
 24.2 Nothing contained in this Lease shall be construed as creating a partnership or joint venture of or between Landlord and Tenant, or to create
any other relationship between the parties hereto other than that of landlord and tenant. 
 24.3 Tenant represents and warrants that
Tenant has not dealt directly or indirectly with any broker or agent in connection with this Lease other than Rackhouse Group, LLC (“Broker”). The execution and delivery of this Lease by Landlord shall be conclusive evidence
that Landlord has relied upon the forgoing representation and warranty. Tenant agrees to

indemnify and hold Landlord harmless from and against any claims for commissions, fees or other compensation by any person or entity, other than Broker, who
shall claim to have dealt with Tenant in connection with this Lease and for any and all costs incurred in connection with such claims, including, without limitation, reasonable attorneys’ fees and disbursements. Landlord agrees to pay any
commission or compensation due Broker in connection with this Lease pursuant to a separate written agreement between Landlord and Broker (any such commission paid to Broker, the “Brokerage Commission”). 
 24.4 Tenant agrees, at any time and from time to time, upon not less than ten (10) days’ prior written notice by Landlord, to execute,
acknowledge and deliver to the requesting party a statement in writing (i) certifying, if true, that this Lease is unmodified and in full force and effect (or if there have been any modifications, that the Lease is in full force and effect as
modified and stating the modifications); (ii) stating the dates to which the rent and any other charges hereunder have been paid by Tenant; (iii) stating whether or not, to the best knowledge of Tenant, Landlord is in default in the
performance of any covenant, agreement or condition contained in this Lease, and if so, specifying the nature of such default; (iv) stating the address to which notices to Tenant are to be sent; and (v) stating such other information as
Landlord or any mortgagee or prospective mortgagee of the Building may reasonably request. Any such statement delivered by Tenant may be relied upon by any landlord of the Building or the Land, any prospective purchaser of the Building or the Land,
any mortgagee or prospective mortgagee of the Building or the Land or of Landlord’s interest therein, or any prospective assignee of any such mortgagee. 
 24.5 LANDLORD AND TENANT EACH HEREBY WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER OF THEM AGAINST THE OTHER IN CONNECTION WITH ANY MATTER ARISING OUT OF OR IN ANY WAY
CONNECTED WITH THIS LEASE, THE RELATIONSHIP OF LANDLORD AND TENANT HEREUNDER, TENANT’S USE OR OCCUPANCY OF THE PREMISES, AND/OR ANY CLAIM OF INJURY OR DAMAGE.

 Either party may change its address for the giving of notices by notice given in accordance with this
Section 24.6. 
 24.7 If any provision of this Lease or the application thereof to any person or circumstances shall to any
extent be invalid or unenforceable, the remainder of this Lease, or the application of such provision to persons or circumstances other than those as to which it is invalid or unenforceable, shall not be affected thereby, and each provision of this
Lease shall be valid and enforced to the fullest extent permitted by law. 
 24.8 Feminine or neuter pronouns shall be substituted for
those of the masculine form, and the plural shall be substituted for the singular number, in any place or places herein in which the context may require such substitution. 
 24.9 The provisions of this Lease shall be binding upon, and shall inure to the benefit of, the parties hereto and each of their respective
representatives, successors and assigns, subject to the provisions hereof restricting assignment or subletting by Tenant. 
 24.10
This Lease contains and embodies the entire agreement of the parties hereto and supersedes all prior agreements, negotiations and discussions between the parties hereto. Any representation, inducement or agreement that is not contained in this
Lease shall not be of any force or effect. This Lease may not be modified or changed in whole or in part in any manner other than by an instrument in writing duly signed by both parties hereto. 
 24.11 This Lease shall be governed by and construed in accordance with the laws of the Commonwealth of Virginia. 
 24.12 Article and section headings are used herein for the convenience of reference and shall not be considered when construing or interpreting
this Lease. 
 24.13 The submission of an unsigned copy of this document to Tenant for Tenant’s consideration does not constitute
an offer to lease the Premises or an option to or for the Premises. This document shall become effective and binding only upon the execution and delivery of this Lease by both Landlord and Tenant. 
 24.14 Time is of the essence with respect to each provision of this Lease. 
 24.15 Neither this Lease nor a memorandum thereof shall be recorded; however, this Section 24.15 shall not be construed as prohibiting the
recordation of the SNDA in accordance with Section 20.3 above. 
 24.16 Except as otherwise provided in this Lease, any
additional rent or other sum owed by Tenant to Landlord, and any cost, expense, damage or liability incurred by Landlord for which Tenant is liable, shall be considered “Additional Rent” and unless otherwise provided in this
Lease, shall be paid by Tenant to Landlord no later than thirty (30) days after the date Landlord notifies Tenant of the amount of such Additional Rent or such cost, expense, damage or liability.

 24.17 For purposes of this Lease, “Business Day” shall mean a day
other than a Saturday, Sunday or Federal holiday. 
 24.18 Except as expressly set forth herein to the contrary, all of the
parties’ duties and obligations hereunder shall survive the termination of this Lease for any reason whatsoever. 
 24.19 If
Landlord or Tenant is in any way delayed, interrupted or prevented from performing any obligation (except, with respect to Tenant, its obligations to pay rent and other sums due under this Lease, any obligation with respect to insurance pursuant to
Article XII, and any obligation to give notice with respect to extensions, expansions or otherwise due to fire, act of God, governmental act or failure to act, war, enemy action, strike, labor dispute, inability to procure materials, or any cause
beyond Landlord’s or Tenant’s (as applicable) reasonable control (whether similar or dissimilar to the foregoing events) (all of which are collectively referred to herein as “Force Majeure”), then the time for
performance of such obligation shall be excused for the period of such delay, interruption or prevention and extended for a period equal to the period of such delay or prevention. Notwithstanding the foregoing, neither financial disability or
hardship shall constitute a Force Majeure event. By way of clarification, the occurrence of an event of Force Majeure will not prevent the occurrence of a Power Deficiency or HVAC Deficiency and same shall be determined without regard to such Force
Majeure. 
 24.20 Each party hereby represents and warrants to the other that all necessary corporate or company action has been taken
to enter into this Lease and that the person signing this Lease on behalf of such party has been duly authorized to do so and all consents required by such party to enter into this Lease have been received and no further consent from any party is
required to enter into this Lease.

 ARTICLE XXV 
 RENEWAL 
 25.1 Landlord hereby grants to Tenant two (2) successive five (5)-year renewal
options, each exercisable at Tenant’s option and subject to the conditions described below (each such five-year term, if exercised, being referred to herein as a “Renewal Term”). If such right is exercised, and if the
conditions applicable thereto have been satisfied, the first Renewal Term shall commence immediately following the end of the Lease Term provided in this Lease and the second Renewal Term shall commence immediately following the end of the first
Renewal Term. The right of renewal herein granted to Tenant shall be subject to, and shall be exercised in accordance with, the following terms and conditions: 
 (a) Tenant shall exercise its right of renewal with respect to each Renewal Term by giving Landlord written notice thereof not earlier than eighteen (18) months and not later than twelve (12) months
prior to the expiration date of the then-current Lease Term (the “Renewal Notice”). 
 (b) In the event the
Renewal Notice is not given timely, Tenant’s right of renewal shall lapse and be of no further force or effect. 
 (c) All the
terms, conditions, covenants and agreements set forth in this Lease shall continue to apply and be binding upon Landlord and Tenant during each Renewal Term, except for the determination of Base Rent which shall be as set forth in Section 25.2
below. 
 (d) In the event there exists an Event of Default on the date of receipt of a Renewal Notice or anytime thereafter until the
date such Renewal Term is to commence, then, at Landlord’s option, such Renewal Term shall not commence and the Lease Term shall expire at the date the Lease Term would have expired without such renewal. 
 (e) The renewal option shall be exercised only by the original Tenant hereunder or by an Affiliate of the original Tenant hereunder, and not by
any other assignee, transferee or subtenant. In the event the original Tenant assigns this Lease to any entity other than an Affiliate of the original Tenant, Tenant’s rights under this Section 25.1 shall lapse as though this
Section 25.1 had never been included in the Lease. 
 (f) In the event this Lease is not renewed for the first Renewal Term,
Tenant’s right to renew this Lease for the second Renewal Term shall lapse and be of no further force and effect. 
 25.2 (a) The
Base Rent charged for the first year of each Renewal Term shall be [*****].

 ARTICLE XXVI 
 COMMUNICATIONS EQUIPMENT 
 26.1 (a) Subject to the terms and conditions in this Article XXVI, Tenant shall have the license, at Tenant’s sole risk, cost and expense, to
install and maintain in a designated location on the roof of the Building (the “Satellite Area”) one (1) or more satellite dish antennae (together and singly the “antenna”), together with the
cables extending from such antenna to the Premises through plenums, risers, electrical closets, ducts or pipes on or serving the floor on which the Premises are located (other than those installed for another tenant’s exclusive use and provided
Tenant shall have utilization of each such facility or area in no greater proportion than the ratio by which the square feet of rentable area in the Premises compares to the square feet of rentable area in the Building), all in accordance with plans
and specifications to be reasonably approved by Landlord. The number, location, size, weight, height and all other features and specifications of the antenna and the manner of the initial installation of the same shall be subject to Landlord’s
prior written approval, which approval will not be unreasonably withheld, conditioned or delayed. The installation of such antenna and all related wiring and equipment shall be performed during normal working hours and under the supervision of
Landlord’s designated representative. Notwithstanding the foregoing, Tenant shall not be entitled to install such an antenna (i) which is greater than three (3) meters in diameter (or more if same is not visible from the grounds
adjacent to the Building or appropriately screened from view in accordance with Building standards), (ii) which is more than four (4) meters in height (or more if same is not visible from the grounds adjacent to the Building or
appropriately screened from view in accordance with Building standards), (iii) if such installation would violate (or in a manner that would violate) any warranty with respect to the roof or structure of the Building, (iv) if such
installation would materially, adversely affect (or in a manner that would materially, adversely affect) the structure or any of the building systems of the Building, or if such installation would require (or in a manner that would require) any
structural alteration to the Building, or if such installation would disturb the roof membrane or make any other penetration on the roof or the exterior facade of the Building, unless Landlord in its sole and absolute discretion approves in writing
such structural alteration or roof penetration, (v) if such installation would violate (or in a manner that would violate) any covenant, condition, or restriction of record affecting the Building or any applicable federal, state or local law,
rule or regulation, (vi) unless all required approvals and consents of all holders of Mortgages encumbering the Building of whom Tenant has notice are obtained (to the extent required by the loan documents and requested by Landlord),
(vii) unless Tenant has obtained and maintains at Tenant’s expense, and has submitted to Landlord copies of, all permits, licenses, special zoning variances, authorizations and approvals relating to such antenna and such installation and
maintenance (including, without limitation, any permit required if a crane is necessary to place such antenna on the roof) and pays all taxes and fees related thereto, (viii) unless such antenna is white or of a beige or lighter color (or
otherwise appropriately screened), (ix) unless such antenna is installed, at Tenant’s sole cost and expense, by a qualified contractor chosen by Tenant and approved in advance by Landlord, which approval shall not be unreasonably withheld,
(x) if the installation or operation would materially interfere with or materially disrupt

the use or operation of any other equipment (including antennae) on the roof of the Building on the Lease Commencement Date, (xi) unless Tenant obtains
Landlord’s prior consent to the manner and time in which such installation work is to be done; and (xii) unless screened from view from the grounds adjacent to the Building in a manner and with materials reasonably acceptable to Landlord.
All plans and specifications concerning such installation shall be subject to Landlord’s prior written approval, which approval shall not be unreasonably withheld, and Tenant shall reimburse Landlord’s reasonable and customary third-party
expenses actually incurred in such review. All maintenance, repairs and installations required after the initial installation of the antenna also shall be subject to Landlord’s prior written approval, which approval shall not be unreasonably
withheld, and Tenant shall reimburse Landlord’s reasonable and customary third-party expenses actually incurred in such review. Any failure to complete the installation of the antenna and related equipment shall not delay the Lease Commencement
Date. Tenant shall have no right to any abatement or reduction in the Base Rent, Additional Rent or any other sums due or payable under this Lease if for any reason Tenant is unable to obtain any required approval for installation of an antenna, or
is thereafter unable to use the antenna for any reason. 
 (b) Tenant shall not have access to any such antenna without
Landlord’s prior consent, which consent shall be granted to the extent necessary or desirable for Tenant to perform its maintenance, repair, replacement or other obligations hereunder, and only if Tenant is accompanied by Landlord’s
representative (if Landlord so requests and no emergency circumstances required otherwise, and provided such representative of Landlord does not interfere with or delay Tenant in exercising its rights or satisfying its obligations hereunder). Any
such access by Tenant shall be subject to reasonable rules and regulations relating thereto established from time to time by Landlord, including without limitation rules and regulations prohibiting such access unless Tenant is accompanied by
Landlord’s representative, provided such representative of Landlord does not interfere with or delay Tenant in exercising its rights or satisfying its obligations hereunder. Landlord shall have the right to access the Satellite Area at all
times, provided Landlord does not unreasonably interfere with Tenant’s use of the Satellite Area and any antenna as provided herein. Notwithstanding the foregoing, in the event Tenant is prevented or delayed from satisfying its obligations
under this Article XXVI due to Landlord’s failure to consent to Tenant’s access to the Satellite Area and any such antenna and/or Landlord’s requirement of a Landlord escort, then Tenant’s obligations shall be excused until
Landlord issues such consent and/or produces any such Landlord escort. 
 (c) At all times during the Lease Term, Tenant shall
(i) perform maintenance and repairs so as to keep all said equipment in clean, good and safe condition and in a manner that avoids material interference with or material disruption to Landlord and other tenants of the Building, (ii) comply
with all requirements of laws, ordinances, rules and regulations of all public authorities and insurance companies which shall impose any order or duty upon Landlord with respect to or affecting the antenna and/or associated wiring or Tenant’s
use or manner of use thereof, and (iii) register the equipment, if required, with appropriate governmental authorities and keep same current. All repairs and maintenance shall be performed by a qualified Approved Contractor. Tenant shall pay
and discharge all costs and expenses incurred in connection with the furnishing, installation, maintenance, operation and removal of the antenna. All repairs and maintenance to the Building made necessary by reason of the furnishing,

installation, maintenance, operation or removal of the antenna or any replacements thereof (including, without limitation, any invalidation of the roof
warranty due to Tenant’s breach of its obligations hereunder) shall be at Tenant’s sole cost. If the operation of the antenna shall require electrical power, Landlord may, at its sole option, install a separate meter, at Tenant’s sole
expense, to measure such electrical consumption and Tenant shall pay for such consumption at the then-current price per kilowatt hour charged Landlord by the utility. At the expiration or earlier termination of the Lease Term, or upon termination of
the operation of the antenna and related equipment as provided in subsection (e) below, Tenant shall remove such antenna and related equipment from the Building and surrender the Satellite Area in good condition, ordinary wear and tear and
damage by fire, casualty and the elements excepted. If Tenant fails to so remove the antenna and equipment in accordance with the foregoing, Landlord shall have the right to remove and dispose of such antenna and equipment, at Tenant’s sole
cost and expense, and Landlord shall have no liability therefor. Notwithstanding the foregoing to the contrary, in the event any repairs or maintenance to, or restoration of, the Building made necessary by reason of furnishing, installation,
maintenance, operation or removal of the antenna or any replacements thereof are due to work performed or to be performed by DFTS pursuant to a separate agreement between DFTS and Tenant, then Landlord, and not Tenant, shall be responsible therefor
at Landlord’s sole cost and expense. 
 (d) Upon at least thirty (30) days’ prior written notice to Tenant, Landlord
shall have the right to require Tenant to relocate the antenna to another location of equivalent size; provided, however, that such relocation: (i) does not materially, adversely affect the operation of the antenna; and (ii) can be
performed without any interruption in service. Any such relocation shall be performed by Tenant at Landlord’s expense, and in accordance with all of the requirements of this Article XXVI. Nothing in this Section shall be construed as granting
Tenant any line of sight easement with respect to such satellite dish antenna; provided, however, that if Landlord requires that such antenna be relocated in accordance with the preceding two (2) sentences, then Landlord shall provide either
(i) the same line of sight for such antenna as was available prior to such relocation, or (ii) a line of sight for such antenna which is functionally equivalent to that available prior to such relocation. 
 (e) It is expressly understood that by granting Tenant the license hereunder, Landlord makes no representation as to the legality of such antenna
or its installation. In the event that any federal, state, county, regulatory or other authority requires the removal or relocation of such antenna, Tenant shall remove or relocate such antenna at Tenant’s sole cost and expense, and Landlord
shall under no circumstances be liable to Tenant therefor. In addition, at Landlord’s sole option and discretion, Landlord may require Tenant, at any time prior to the expiration or earlier termination of this Lease, to terminate the operation
of the antenna and related equipment if it is causing material physical damage to the structural integrity of the Building, materially interfering with any other service provided to the Building in existence as of the Lease Commencement Date or
causing the violation of any condition or provision of this Lease. The right granted to Tenant under this Article XXVI are non-exclusive, non-transferable (except to an Affiliate or in connection with a permitted sublease of the entire Premises or
assignment of the Lease in its entirety pursuant to Article VII hereof), revocable license to use the Satellite Area solely in accordance with terms and conditions of this Article XXVI.

 (f) Tenant shall indemnify and hold Landlord harmless from and against all costs, damages,
claims, liabilities and expenses (including attorneys’ fees) suffered by or claimed against Landlord, directly or indirectly, based on, arising out of or resulting from any act or omission by Tenant or Tenant’s employees, agents,
assignees, subtenants, contractors, clients, guests, licensees, customers or invitees with respect to the installation, use, operation, maintenance, repair, removal or disassembly of such antenna and related equipment (including, without limitation,
any damage to other wires or equipment of the Building or other tenants/occupants of the Building). 
 (g) The antenna may be used by
Tenant only in the conduct of Tenant’s customary business. No assignee or subtenant shall have any rights pursuant to this Article except for an Affiliate or an assignee of the entire Lease or a subtenant of the entire Premises pursuant to a
permitted assignment or sublease in accordance with Article VII hereof. 
 (h) Tenant shall maintain such insurance (in addition to
that required by Article XII of this Lease) as is appropriate with respect to the installation, operation and maintenance of the antenna. Landlord shall have no liability on account of any damage to or interference with the operation of the antenna,
except for physical damage caused by Landlord’s gross negligence or willful misconduct not covered by Tenant’s insurance carried or required to be carried by said Article XII, and Landlord expressly makes no representations or warranties
with respect to the capacity for an antenna placed on the roof of the Building to receive or transmit signals. Except as otherwise expressly provided herein, the operation of the antenna shall be at Tenant’s sole and absolute risk. Tenant shall
in no event materially interfere with the use of any other communications equipment located on the roof, or anywhere else in, the Building pursuant to leases or other agreements entered into prior to the date of the Lease and will reasonably
cooperate with Landlord, at no cost or expense to Tenant, to avoid material interference with any other antennas or equipment installed in the future.

 ITI (CBEMA) CURVE APPLICATION NOTE 
 The ITI (CBEMA) Curve, included within this Application Note, is published by Technical Committee 3 (TC3) of the Information Technology Industry Council,
(ITI, formerly known as the Computer & Business Equipment Manufacturers Association). It is available at http://.www.itic.org/technical/iticurv.pdf. 
  

	1)	SCOPE 

 The ITI (CBEMA) Curve and this Application Note
describe an AC input voltage envelope which typically can be tolerated (no interruption in function) by most Information Technology Equipment (ITE). The Curve and this Application Note comprise a single document and are not to be considered
separately from each other. They are not intended to serve as a design specification for products or AC distribution systems. The Curve and this Application Note describe both steady-state and transitory conditions. 
  

	2)	APPLICABILITY 

 The Curve and this Application Note are
applicable to 120V nominal voltages obtained from 120V, 208Y/120V, and 120/240V 60Hz systems. Other nominal voltages and frequencies are not specifically considered and it is the responsibility of the user to determine its applicability of these
documents for such conditions. 
  

	3)	DISCUSSION 

 This section provides a brief description of
the individual conditions which are considered in the Curve. For all conditions, the term “nominal voltage” implies an ideal condition of 120V RMS, 60Hz. 
 Seven types of events are described in this composite envelope. Each event is briefly described in the following sections, with two similar line voltage sags being described under a single heading. Two regions outside
the envelope are also noted. All conditions are assumed to be mutually exclusive at any point in time, and with the exception of steady-state tolerances, are assumed to commence from the nominal voltage. The timing between transients is assumed to
be such that the ITE returns to equilibrium (electrical, mechanical, and thermal) prior to commencement of the next transient. 
  

	3.1)	Steady-State Tolerances 

 The steady-state range describes
an RMS voltage which is either very slowly varying or is constant. The subject range is 
 +/- 10% from the nominal voltage. Any voltages in
this range may be present for an indefinite period, and are a function of normal loadings and losses in the distribution system. 
  

	3.2)	Line Voltage Swell 

 This region describes a voltage swell
having an RMS amplitude of up to 120% of the RMS nominal voltage, with a duration of up to 0.5 seconds. This transient may occur when large loads are removed from the system or when voltage is supplied from sources other than the electric utility.

  

	3.3)	Low-Frequency Decaying Ringwave 

 This region describes a
decaying ringwave transient which typically results from the connection of power-factor-correction capacitors to an AC distribution system. The frequency of this transient may range from 200Hz to 5KHz, depending upon the resonant frequency of the AC
distribution system. The magnitude of the transient is expressed as a percentage of the peak 60Hz nominal voltage (not the RMS value). The transient is assumed to be completely decayed by the end of the half-cycle in which it occurs. The
transient is assumed to occur near the peak of the nominal voltage waveform. The amplitude of the transient varies from 140% for 200Hz ringwaves to 200% for 5KHz ringwaves, with a linear increase in amplitude with increasing frequency. Refer to
Figure 1 for an example of a typical waveform.

	3.4)	High-Frequency Impulse Ringwave 

 This region describes the
transients which typically occur as a result of lightning strikes. Wave shapes applicable to this transient and general test conditions are described in ANSI/IEEE C62.41-1991. This region of the curve deals with both amplitude and duration (energy),
rather than RMS amplitude. The intent is to provide an 80 Joule minimum transient immunity. 
  

	3.5)	Voltage Sags 

 Two different RMS voltage sags are
described. Generally, these transients result from application of heavy loads, as well as fault conditions, at various points in the AC distribution system. Sags to 80% of nominal (maximum deviation of 20%) are assumed to have a typical duration of
up to 10 seconds, and sags to 70% of nominal (maximum deviation of 30%) are assumed to have a duration of up to 0.5 seconds. 
  

	3.6)	Dropout 

 A voltage dropout includes both severe RMS
voltage sags and complete interruptions of the applied voltage, followed by immediate re-application of the nominal voltage. The interruption may last up to 20 milliseconds. This transient typically results from the occurrence and subsequent
clearing of faults in the AC distribution system. 
  

	3.7)	No Damage Region 

 Events in this region include sags and
dropouts which are more severe than those specified in the preceding paragraphs, and continuously applied voltages which are less than the lower limit of the steady-state tolerance range. The normal functional state of the ITE is not typically
expected during these conditions, but no damage to the ITE should result. 
  

	3.8)	Prohibited Region 

 This region includes any surge or swell
which exceeds the upper limit of the envelope. If ITE is subjected to such conditions, damage to the ITE may result.

Ventures LLC, a Delaware limited liability company, as landlord (“Landlord”), and Tenant, as tenant (as amended, the “Lease”); and 
 B. Landlord is the owner in fee simple of the Property and the landlord under the Lease (“Landlord”); and 
 C. Lender is the agent for lenders which have made a loan (the “Loan”) or are about to make a loan to Landlord, as borrower, having its principal place of business at 1212 New York Avenue, NW, Suite 900, Washington, D.C. 20005,
evidenced or to be evidenced by one or more promissory notes made by Landlord to the order of such lenders (collectively, the “Note”) and secured or to be secured by that certain Deed of Trust, Assignment of Leases and Rents, Security
Agreement and Fixture Filing (the “Security Instrument”) and that certain Assignment of Leases and Rents (the “Assignment of Rents”) granted by Landlord to or for the benefit of Lender and encumbering the Property; and

 2. NON-DISTURBANCE. If any action or proceeding is commenced by Lender for the foreclosure of
the Security Instrument or the sale of the Property, Tenant shall not be named as a party therein unless such joinder shall be required by law, provided, however, such joinder shall not result in the termination of the Lease or disturb the
Tenant’s possession or use of the premises demised thereunder, and the sale of the Property in any such action or proceeding and the exercise by Lender of any of its other rights under the Note or the Security Instrument shall be made subject
to all rights of Tenant under the Lease and shall not disturb Tenant’s right of possession or use of the premises demised thereunder, provided that at the time of the commencement of any such action or proceeding or at the time of any such sale
or exercise of any such other rights Tenant shall not be in default under any of the terms, covenants or conditions of the Lease or of this Agreement on Tenant’s part to be observed or performed beyond any applicable notice or grace period.

 3. ATTORNMENT. If Lender or any other subsequent purchaser of the Property shall become the owner of the Property by reason of the
foreclosure of the Security Instrument or the acceptance of a deed or assignment in lieu of foreclosure or by reason of any other enforcement of the Security Instrument (Lender or such other purchaser being hereinafter referred to as
“Purchaser”), and the conditions set forth in Section 2 above have been met at the time Purchaser becomes owner of the Property, the Lease shall not be terminated or affected thereby but shall continue in full force and effect as a
direct lease between Purchaser and Tenant upon all of the terms, covenants and conditions set forth in the Lease and in that event, Tenant agrees to attorn to Purchaser and Purchaser by virtue of such acquisition of the Property shall be deemed to
have agreed to accept such attornment, whereupon, subject to the observance and performance by Tenant of all the terms, covenants and conditions of the Lease on the part of Tenant to be observed and performed, Purchaser shall recognize the leasehold
estate of Tenant under all of the terms, covenants and conditions of the Lease for the remaining balance of the term with the same force and effect as if Purchaser were the lessor under the Lease subject to the terms of Section 4 of this
Agreement; provided, however, that Purchaser shall not be: 
  

	 	(a)	liable for the failure of any prior landlord (any such prior landlord, including Landlord and any successor landlord, being hereinafter referred to as a “Prior Landlord”)
to perform any of its obligations under the Lease which have accrued prior to the date on which Purchaser shall become the owner of the Property, provided that the foregoing shall not limit Purchaser’s liability for, and obligations under the
Lease to correct, any conditions that (i) existed as of the date Purchaser shall become the owner of the Property and (ii) violate Purchaser’s obligations as landlord under the Lease; provided further, however, that Purchaser shall
have received written notice of such omissions, conditions or violations and has had an opportunity to cure the same as provided in Section 5 below, all pursuant to the terms and conditions of the Lease; 

  

	 	(b)	subject to any offsets, defenses, abatements or counterclaims which shall have accrued in favor of Tenant against any Prior Landlord prior to the date upon which Purchaser shall
become the owner of the Property, except for (i) the right to recapture from rent any reasonable amounts expended by Tenant to cure a default of any Prior Landlord for which Lender had received a copy of notice pursuant to the terms hereof and
would have been required to cure upon succeeding to the interest of Prior Landlord, and (ii) any rental abatements and/or credits available to Tenant pursuant to Article 16 or Article 17 of, or the Services Exhibit attached as Exhibit F
to, the Lease; 

  

	 	(c)	liable for damages for any breach, act or omission of any Prior Landlord which have accrued prior to the time Purchaser succeeded to any Prior Landlord’s interest under the
Lease by reason of the foreclosure of the Security Instrument or the acceptance of a deed or assignment in lieu of foreclosure or by reason of any other enforcement of the Security Instrument; 

  

	 	(d)	liable for the return of rental security deposits, if any, paid by Tenant to any Prior Landlord in accordance with the Lease unless such sums are actually received by Purchaser;

  

	 	(e)	bound by any obligation which may appear in the Lease to perform any initial improvement work to the Property to prepare the premises demised under the Lease for occupancy by
Tenant;

		  	CONFIDENTIAL MATERIAL HAS BEEN OMITTED AND
		  	FILED SEPARATELY WITH THE SECURITIES AND
		  	EXCHANGE COMMISSION. BOXES AND ASTERIXES
		  	DENOTE SUCH OMISSION

  

	 	(f)	bound by any payment of rents, additional rents or other sums which Tenant may have paid more than one (1) month in advance to any Prior Landlord unless (i) such sums are
actually received by Purchaser or (ii) such prepayment shall have been expressly approved of by Purchaser; 

  

	 	(g)	subject to the terms and provisions of Section 7 below, bound by any obligation to make any payment to Tenant which was required to be made prior to the time Purchaser
succeeded to any Prior Landlord’s interest under the Lease by reason of the foreclosure of the Security Instrument or the acceptance of a deed or assignment in lieu of foreclosure or by reason of any other enforcement of the Security
Instrument, except for any payments resulting from any rental abatements and/or credits available to Tenant pursuant to Article 16 or Article 17 of, or the Services Exhibit attached as Exhibit F to, the Lease; 

  

	 	(h)	bound by any amendment or modification of the rent, term or other material term of the Lease made without Lender’s or Purchaser’s prior written consent prior to the time
Purchaser succeeded to Landlord’s interest, provided, however, that no consent from Lender or Purchaser shall be required to any amendment or modification (including, without limitation, termination) of the Lease either expressly provided for
in the Lease or entered into as a result of Tenant’s exercise of any renewal, expansion, first refusal, first offer or other options or rights contained in the Lease; or 

  

	 	(i)	responsible for the making of repairs in or to the Property in the case of damage or destruction to the Property or any part thereof due to fire or other casualty or by reason of
condemnation unless Purchaser is obligated under the Lease to make such repairs and Purchaser receives insurance proceeds (or would have received insurance proceeds if Purchaser maintained the insurance required of Landlord under Article XII of the
Lease) or condemnation awards sufficient to finance the completion of such repairs. 

 In the event that any liability of
Purchaser does arise pursuant to this Agreement, such liability shall be limited and restricted to Purchaser’s interest in the Property (and the rents, issues and profits derived therefrom and, in the event of a sale thereof, the proceeds of
any such sale) and shall in no event exceed such interest. 
 4. NOTICE TO TENANT. After written notice is given to Tenant by Lender
that the Landlord is in default under the Note and the Security Instrument and that the rentals under the Lease should be paid to Lender pursuant to the terms of the Assignment of Rents executed and delivered by Landlord to Lender in connection
therewith, Tenant shall thereafter pay to Lender or as directed by the Lender, all rentals and all other monies due or to become due to Landlord under the Lease and Landlord hereby expressly authorizes Tenant to make such payments to Lender and
hereby releases and discharges Tenant from any liability to Landlord on account of any such payments. 
 5. NOTICE TO LENDER AND RIGHT TO
CURE. Subject to the terms and provisions of this Section 5 contained herein below, Tenant further agrees that, notwithstanding any provisions of the Lease other than the Services Exhibit attached as Exhibit F to the Lease and except
as otherwise expressly provided herein below, no cancellation or termination of the Lease and no abatement or reduction of the rent or management fees payable thereunder due to a default on the part of Landlord under the Lease shall be effective
unless Lender has received notice of the same and has failed within thirty (30) days after both Lender’s receipt of said notice and the time when Lender shall have become entitled under the Security Instrument to remedy the same, to
commence to cure the default which gave rise to the cancellation or termination of the Lease or abatement or reduction of the rent or management fee payable thereunder and thereafter fails to diligently prosecute such cure to completion, provided
that in the event Lender cannot commence such cure without possession of the Property, no cancellation or termination of the Lease and no abatement or reduction of the rent or management fees payable thereunder shall be effective if Lender commences
judicial or non judicial proceedings to obtain possession within such thirty (30) day period and thereafter diligently prosecutes such efforts and cure to completion. Notwithstanding the foregoing, Lender shall have no obligation to cure any
default by Landlord except as provided in Section 3 above in the event Lender shall become the owner of the Property by reason of the foreclosure of the Security Instrument or the acceptance of a deed or assignment in lieu of foreclosure or by
reason of any other enforcement of the Security Instrument. Furthermore, notwithstanding anything to the contrary contained herein, the requirements of notice and

		  	FILED SEPARATELY WITH THE SECURITIES AND
		  	EXCHANGE COMMISSION. BOXES AND ASTERIXES

an opportunity to cure afforded to Lender as set forth in this Section 5 shall not apply to any rent abatements and/or credits or termination rights:
(a) set forth in Part C. of the Services Exhibit attached as Exhibit F to the Lease or (b) (i) that do not arise from a default on the part of the “Landlord” under the Lease and/or (ii) for which such a right or
remedy in favor of Tenant ensues without the requirement of notice and an opportunity to cure being afforded to Landlord; provided, however Tenant agrees to notify Lender as provided in Section 8 below of any default on the part of Landlord
under the Lease which would entitle Tenant to cancel or terminate the Lease or to abate or reduce the rent or management fees payable thereunder. 
 6. CASUALTY AND CONDEMNATION. Tenant understands and agrees that if the Property or any portion thereof are damaged by fire or other casualty, or are taken by eminent domain proceedings, any insurance proceeds or condemnation awards
attributable to such casualty or condemnation proceeding shall be subject to, and shall be distributed in accordance with, the terms of the Security Instrument and other documents relating to the Loan. 
 7. BUILD-OUT ALLOWANCE. Notwithstanding anything to the contrary contained herein, in the event Purchaser shall become the owner of the Property
by reason of the foreclosure of the Security Instrument or the acceptance of a deed or assignment in lieu of foreclosure or by reason of any other enforcement of the Security Instrument and Tenant provides Purchaser (i) written notice that
Landlord failed to pay when due all or any portion of the Build-out Allowance (as defined in the Lease) and (ii) copies of the other documents required to be delivered by Tenant under Section 9.4 of the Lease for payment of the Build-out
Allowance (“Tenant Allowance Notice”), then, within thirty (30) days of its receipt of the Tenant Allowance Notice, Purchaser shall, at Purchaser’s election, either pay the portion of the Build-out Allowance due Tenant pursuant
to terms of Section 9.4 of the Lease, or notify Tenant in writing that Tenant is entitled to, and will receive, a credit against monthly Base Rent due under the Lease in an amount equal to the total amount of the Build-out Allowance due Tenant
as required under Section 9.4 of the Lease (“Build-out Rental Credits”). The total of Build-out Rental Credits to be credited by Purchaser to Tenant in a single calendar month for such month shall not exceed one hundred percent
(100%) of the Base Rent due under the Lease for such month and any unapplied balance of the Build-out Rental Credits shall be carried forward to the next month for which Base Rent is payable. Landlord hereby acknowledges and agrees to provide
Lender with copies of any written correspondence from Landlord to Tenant regarding payment or non-payment of the Build-out Allowance, provided, that, Landlord’s failure to so provide any such copies of written correspondence to Lender shall in
no way affect or impair Tenant’s rights and entitlements under this Section 7. 
 8. NOTICES. Any notice, demand, request or
other communication which any party hereto may be required or may desire to give hereunder shall be in writing and shall be deemed to have been properly given (a) if hand delivered, when delivered; (b) if mailed by United States Certified
Mail (postage prepaid, return receipt requested), three Business Days after mailing (c) if by Federal Express or other reliable overnight courier service, on the next Business Day after delivered to such courier service or (d) if by
telecopier on the day of transmission if confirmed receipt is obtained:

 EXHIBIT H 
 FORM OF GUARANTY 
 THIS GUARANTY is made as of January
            , 2009, by RACKSPACE HOSTING, INC., a Delaware corporation, having an address at 5000 Walzem Road, San Antonio, Texas 78218 (“Guarantor”), to GRIZZLY VENTURES
LLC, a Delaware limited liability company (“Landlord”), having an address at 1212 New York Avenue, N.W., Suite 900, Washington, D.C. 20005. 
 WHEREAS, Landlord has leased to Rackspace US, Inc., a Delaware corporation (“Tenant”), certain space (the “Premises”) in the data center facility known as ACC4 and located in Ashburn
Corporate Center, Ashburn, Virginia, pursuant to that certain Deed of Lease by and between Landlord and Tenant dated as of January             , 2009 (the “Lease”);

 WHEREAS, Guarantor is materially benefited by the Lease, and Guarantor’s executing this Guaranty is a material inducement to Landlord
to enter into the Lease. 
 NOW THEREFORE, in consideration of the premises, and of other good and valuable consideration the receipt and
sufficiency of which are hereby acknowledged, Guarantor agrees with Landlord as follows: 
 1. Guarantor unconditionally and irrevocably
guarantees that all sums stated in the Lease to be payable by Tenant shall be promptly paid in full when due in accordance with the Lease and that Tenant shall perform and observe its covenants thereunder. If any such sum or covenant is not timely
paid, performed or observed, then Guarantor shall, within ten (10) business days of receipt of written demand from Landlord, pay the same regardless of (a) whether Landlord shall have taken any steps to enforce any rights against Tenant or
any other person, (b) termination of the Lease as a result of Tenant’s default, or (c) any other condition or contingency; provided that no such demand shall be made unless (i) with respect to payments of Base Rent and/or
Additional Rent, an Event of Default has occurred, or (ii) with respect to payment of other sums, Tenant has defaulted in the payment of such sum, both Tenant and Guarantor have received written notice from Landlord of such default and such
defaults shall have remained uncured for a period of twenty (20) days after both Tenant and Guarantor have received notice. Guarantor shall also pay all reasonable expenses of collecting such sum or any part thereof or of otherwise enforcing
this Guaranty, including reasonable attorneys’ fees. This Guaranty is irrevocable, unconditional and absolute. 
 2. Guarantor’s
obligations and covenants under this Guaranty shall in no way be affected or impaired by reason of the happening from time to time of any of the following, whether or not Guarantor has been notified thereof or consented thereto:
(i) Landlord’s waiver of the performance or observance by Guarantor or any other party (other than Tenant) of any covenant or condition contained in the Lease or this Guaranty; (ii) any extension, in whole or in part, of the time for
payment by Tenant or Guarantor of any sums owing or payable under the

		  	FILED SEPARATELY WITH THE SECURITIES AND
		  	EXCHANGE COMMISSION. BOXES AND ASTERIXES

Lease or this Guaranty, or of any other sums or obligations under or arising out of or on account of the Lease or this Guaranty, or the renewal of the Lease
or this Guaranty; (iii) any assignment of the Lease or subletting of the Premises or any part thereof; provided, that, in the event Tenant assigns all of its interest in the Lease or subleases its interest in the Premises in its entirety, other
than to an Affiliate, Guarantor shall not be liable hereunder for any option periods, renewals, extensions or modifications of the Lease negotiated or effected between Landlord and any such assignee/sublessee, unless Guarantor otherwise agrees in
writing; (iv) any modification or amendment (whether material or otherwise) of any of the obligations of Tenant or Guarantor under the Lease or this Guaranty; (v) the doing or the omission of any act referred to in the Lease or this
Guaranty (including the giving of any consent referred to in the Lease or this Guaranty); (vi) Landlord’s failure or delay to exercise any right or remedy available to Landlord or any action on the part of Landlord granting indulgence or
extension in any form whatsoever; (vii) the voluntary or involuntary liquidation, dissolution, sale of any or all of the assets, marshaling of assets and liabilities, receivership, conservatorship, insolvency, bankruptcy, assignment for the
benefit of creditors, reorganization, arrangement, composition or readjustment of, or other similar proceeding affecting, Tenant or Guarantor or any of Tenant’s or Guarantor’s assets; or (viii) the release of Guarantor from the
performance or observation of any covenant or condition contained in the Lease or this Guaranty by operation of law. 
 3. To the extent not
prohibited by law, Guarantor hereby expressly waives (a) any right Guarantor may now or hereafter have to any hearing prior to the attachment of any real or personal property to satisfy Guarantor’s obligations, and (b) the benefits of
any present or future constitution, statute or rule of law which exempts property from liability for debt. Guarantor also expressly waives the provisions of Sections 49-25 and 49-26 of the Code of Virginia (1950), as amended. 
 4. No rejection, disaffirmance or termination of the Lease by Tenant or Tenant’s trustee in bankruptcy pursuant to bankruptcy law or any other law
affecting creditors’ rights, shall be effective to release and/or terminate the continuing liability of Guarantor to Landlord under this Guaranty. 
 5. Notice of acceptance of this Guaranty and notice of any obligations or liabilities contracted or incurred by Tenant are hereby waived by Guarantor. Guarantor hereby waives presentment, notice of dishonor, protest
and notice of non-payment or non-performance. 
 6. This Guaranty shall be construed in accordance with the laws of the jurisdiction in which
the Premises are located, without giving reference to conflict of law principles. 
 7. This Guaranty may not be modified or amended except
by a written agreement duly executed by Guarantor and Landlord. 
 8. Subject to Guarantor’s right to avail itself of any defenses
available to Tenant, Guarantor’s liability shall be primary and joint and several with that of Tenant. Landlord may proceed against Guarantor under this Guaranty without initiating or exhausting any remedy against Tenant, and may proceed
against Tenant and Guarantor separately or

concurrently. If Guarantor consists of more than one person or entity, the liability of each person or entity comprising Guarantor shall be joint and several
with that of all other persons or entities comprising Guarantor, and Landlord may proceed separately or concurrently against any or all persons or entities comprising Guarantor. 
 9. Within ten (10) business days after Landlord’s written request, Guarantor shall execute and deliver to Landlord a written statement
certifying any reasonable matter concerning this Guaranty or the Lease as Landlord may reasonably request.
