 Performance-Based Restricted Stock Agreement 

2013 Stock Incentive Plan 

EXHIBIT A 
 GENERAL
TERMS AND CONDITIONS 
 The terms and conditions of the award of shares of restricted common stock, $0.0001 par value per share, of the Company (the
“Restricted Shares”) made to the Recipient, as set forth on the cover page of this Agreement, and subject to the terms and conditions set forth in the 2013 Stock Incentive Plan (the “Plan”) are as follows: 

1. Award of Restricted Stock. 

(a) The Company hereby grants to the Recipient, effective as of the Agreement Date (as set forth on the Notice of Grant), an Award of
Restricted Stock for the number of Restricted Shares set forth on the Notice of Grant (the “Award Shares”), on the terms and conditions set forth in this Agreement and the Plan. 

(b) The Recipient agrees that the Award Shares shall be subject to the forfeiture provisions set forth in Section 3 of this Agreement and
the restrictions on transfer set forth in Section 4 of this Agreement. 
 2. Earned Shares; Vesting. 

(a) The Recipient shall earn a non-forfeitable right to Award Shares as provided in this Section 2. Except as provided below under
Section 2(b) or 2(c) below, the Recipient shall only have a non-forfeitable right to Award Shares to the extent that (i) the Award Shares have become Earned Shares by satisfying the performance vesting conditions set forth in Exhibit C
– Performance Vesting Conditions and (ii) the Recipient is employed by the Company on the vesting date set forth on the Notice of Grant (the “Vesting Date”). An Award Share that the Recipient has earned a
non-forfeitable right to under any provision of this Section 2 is hereinafter referred to as a “Vested Earned Share.” 

(b) If the Recipient’s employment with the Company is terminated by the Company without Cause, by the Recipient for Good Reason or due to
death or Disability prior to the Vesting Date, then the number of Award Shares that are eligible to become Earned Shares based on the achievement of the performance goals set forth on Exhibit C – Performance Vesting Conditions, as
determined by the Compensation Committee of the Board of Directors (the “Committee”) following the end of the Performance Period but no later than the Vesting Date, shall be pro-rated based on the number of days during which the
Recipient was employed by the Company during the Vesting Period. For the avoidance of doubt, any Award Shares that become Earned Shares following the application of this Section 2(b) shall become Vested Earned Shares on the Vesting Date,
notwithstanding the Recipient’s not being employed by the Company on such date. 

 (c) If the Recipient is employed by the Company upon a Change in Control that occurs on or prior
to the Vesting Date, a number equal to 80% of the Award Shares shall become Vested Earned Shares immediately prior to such Change in Control and any remaining Award Shares shall be forfeited immediately and automatically to the Company in accordance
with Section 3 hereof. 
 3. Forfeiture 

Any Award Share that (i) does not become a Vested Earned Share on the Vesting Date as a result of the pro-rated reduction in the number
of Award Shares eligible to become Earned Shares (after applying Section 2(b) above) or (ii) has not otherwise become a Vested Earned Share on the Vesting Date or, if earlier, a Change in Control (after applying Section 2(c) above),
shall be forfeited immediately and automatically to the Company. Any Award Shares that are forfeited under this Section 3 shall revert to the Company without payment of any consideration to the Recipient, effective as of such event that results
in the forfeiture. The Recipient shall have no further rights with respect to any forfeited Award Shares. 
 4. Restrictions on
Transfer. The Recipient shall not sell, assign, transfer, pledge, hypothecate or otherwise encumber, by operation of law or otherwise an Award Share or any interest therein until it has become a Vested Earned Share. 

5. Issuance and Custody of Certificates. 

(a) The Company shall cause Award Shares to be issued in the Recipient’s name in such a manner as the Committee, in its sole discretion,
deems appropriate, including by book-entry or direct registration (including transaction advices) or the issuance of a stock certificate or certificates, which certificate or certificates shall be held by the Secretary of the Company or a custodian
designated by the Secretary for the Recipient’s benefit until such time as the Award Shares are forfeited to the Company or the restrictions applicable to the Award Shares lapse (i.e., an Award Share becomes a Vested Earned Share). The Award
Shares shall be restricted from transfer and shall be subject to an appropriate stop-transfer order. If any certificate is issued, the certificate shall bear a legend that complies with applicable law and makes appropriate reference to the
restrictions applicable to the Award Shares. To the extent that ownership of the Award Shares is evidenced by a book-entry registration or direct registration (including transaction advices), such registration shall be notated to evidence the
restrictions imposed on such Award Shares. 
 (b) After any Award Shares become Vested Earned Shares, and following payment of the
applicable withholding taxes pursuant to Section 7 hereof, the Company shall promptly cause such Vested Earned Shares (less any shares withheld to pay taxes) to be reissued in the Recipient’s name or in the name of the Recipient’s
beneficiary or estate, as the case may be, in such a manner as the Committee, in its sole discretion, deems appropriate, including by book-entry or direct registration (including transaction advices) or the issuance of a stock certificate or
certificates, free of the restrictions and/or legend described in this Section 5. 

 6. Rights as a Shareholder. Except as otherwise provided in this Agreement, for so long as
the Recipient is the registered owner of the Award Shares, the Recipient shall have all rights as a shareholder with respect to the Award Shares, whether vested or unvested, including, without limitation, rights to vote the Award Shares and act in
respect of the Award Shares at any meeting of shareholders; provided that the payment of dividends on unvested Award Shares shall be deferred until such time as the Award Shares become Vested Earned Shares and with respect to any such Vested Earned
Shares, any deferred dividends shall be paid to the Recipient within 30 days following the Vesting Date. 
 7. Tax Matters. 

(a) Acknowledgements. The Recipient acknowledges that he or she is responsible for obtaining the advice of his own tax advisors with
respect to the Award Shares and is relying solely on such advisors and not on any statements or representations of the Company or any of its agents with respect to the tax consequences relating to the Award Shares. The Recipient understands that the
Recipient (and not the Company) shall be responsible for the Recipient’s tax liability that may arise in connection with the acquisition, vesting and/or disposition of the Award Shares. 

(b) Withholding. The Recipient acknowledges and agrees that the Company has the right to deduct from payments of any kind otherwise due
to the Recipient any federal, state, local or other taxes of any kind required by law to be withheld with respect to the Vested Earned Shares. At such time as the Recipient is not aware of any material nonpublic information about the Company or the
Common Stock, the Recipient shall execute the instructions set forth in Exhibit D attached hereto (the “Automatic Sale Instructions”) as the means of satisfying such tax obligation. If the Recipient does not execute the
Automatic Sale Instructions prior to the Award Shares becoming Vested Earned Shares, then the Recipient agrees that if under applicable law the Recipient will owe taxes at such time on the Vested Earned Shares, the Company shall be entitled to
immediate payment from the Recipient of the amount of any tax required to be withheld by the Company. The Company shall not take any of the actions described in Section 5(b) hereof until it is satisfied that all required withholdings have been
made. 
 8. Miscellaneous. 

(a) Authority of Board. In making any decisions or taking any actions with respect to the matters covered by this Agreement, the Board
of Directors (the “Board”) or any one or more of the committees or subcommittees of the Board to which the Board delegates its powers in accordance with the terms of the Plan shall have all of the authority and discretion, and shall
be subject to all of the protections, provided for in the Plan. All decisions and actions by the Board or any one or more of its committees or subcommittees to which its powers have been delegated with respect to this Agreement shall be made in its
discretion and shall be final and binding on the Recipient. 
 (b) No Right to Continued Service. The Recipient acknowledges and
agrees that, notwithstanding the fact that the vesting of the Award Shares is contingent upon continued employment with the Company (except as otherwise provided in this Agreement), this Agreement does not constitute an express or implied promise of
continued service or confer upon the Recipient any rights with respect to continued service by the Company. 

 (c) Governing Law. This Agreement shall be construed, interpreted and enforced in
accordance with the internal laws of the State of Delaware, without regard to any applicable conflicts of law provisions. 
 (d)
Recipient’s Acknowledgments. The Recipient acknowledges that he or she has read this Agreement, has received and read the Plan, and understands the terms and conditions of this Agreement and the Plan.

 EXHIBIT C 

PERFORMANCE VESTING CONDITIONS 

A. Performance Measures Generally 

The Award Shares (or such lesser number of Restricted Shares subject to this Agreement as is determined in accordance with Section 2(b))
are eligible to become Earned Shares solely based upon the achievement during the Performance Period, as determined by the Committee following the end of the Performance Period but no later than the Vesting Date, of specified levels of
(i) Adjusted Revenue, (ii) Adjusted EBITDA and (iii) Adjusted Free Cash Flow (each, a “Performance Measure”) of the Company’s Constant Contact brand as set forth in B. below. For this purpose: 

“Adjusted Revenue” shall mean: revenue from Constant Contact, Inc., including its direct and indirect subsidiaries,
calculated in accordance with U.S. generally accepted accounting principles, for the Performance Period, assuming that the Company’s acquisition of Constant Contact, Inc. had taken place on January 1, 2016, adjusted to exclude the impact
of any fair value adjustments to deferred revenue resulting from acquisitions. 
 “Adjusted EBITDA” shall mean: net income
(loss) from Constant Contact, Inc., including its direct and indirect subsidiaries, for the Performance Period, assuming that the Company’s acquisition of Constant Contact, Inc. had taken place on January 1, 2016, plus (i) changes in
deferred revenue, depreciation, amortization, stock-based compensation expense, loss of unconsolidated entities, net loss on sale of assets, expenses related to integration of acquisitions and restructurings, transaction expenses and charges,
certain legal advisory expenses, interest expense and income tax expense, less (ii) earnings of unconsolidated entities, net gain on sale of assets and other non-recurring gains. 

“Adjusted Free Cash Flow” shall mean: Adjusted EBITDA, less (i) cash paid for restructuring charges and capital
expenditures, plus or minus (ii) the change in working capital. 
 B. Performance Objectives 

The table below sets forth the target for each Performance Measure: 
  

					
	 Performance Measure
	  	Target	 
	 Adjusted Revenue
	  	$	            	  
	 Adjusted EBITDA
	  	$	 	  
	 Adjusted Free Cash Flow
	  	$	 	  

 The “Attainment Factor” for each Performance Measure shall be the percentage of the target
Performance Measure actually achieved, which percentage may, for the avoidance of doubt, exceed 100%. 

 In calculating the aggregate achievement of the Performance Measures, the Attainment Factor of
each Performance Measure shall be weighted as follows: (i) Adjusted Revenue will be weighted 50%, (ii) Adjusted EBITDA will be weighted 25%, and (iii) Adjusted Free Cash Flow will be weighted 25%. The “Aggregate Achievement
Percentage” shall therefore be equal to the sum of: 
 (i) the product of (x) 50% and (y) the Adjusted Revenue Attainment
Factor for the Performance Period; and 
 (ii) the product of (x) 25% and (y) the Adjusted EBITDA Attainment Factor for the
Performance Period; and 
 (iii) the product of (x) 25% and (y) the Adjusted Free Cash Flow Attainment Factor for the Performance
Period. 
 C. Calculation of Earned Shares 

The percentage of Award Shares (or such lesser number of Restricted Shares subject to this Agreement as is determined in accordance with
Section 2(b)) that become Earned Shares shall be calculated by reference to the following chart. 
  

					
	 Aggregate Achievement Percentage
	  	Earned
Shares	 
	 Less than 90%
	  	 	0	% 
	 90%
	  	 	40	% 
	 95%
	  	 	76	% 
	 100%
	  	 	80	% 
	 Greater than or equal to 105%
	  	 	100	% 

 In calculating the number of Earned Shares, achievement will be linearly interpolated between the percentages
set forth in the tables above. Any fractional number of Restricted Shares resulting from the application of the percentages set forth below shall be rounded to the nearest whole number of Restricted Shares, provided, however, that in no event may
the number of Earned Shares calculated thereby exceed the number of Award Shares subject to this Agreement. 

 EXHIBIT D 

AUTOMATIC SALES INSTRUCTIONS 
 The
undersigned hereby consents and agrees that any taxes due with respect to any Vested Earned Shares shall be paid through an automatic sale of shares as follows: 

(a) Upon the vesting of any Award Shares in accordance with Section 2, the Company shall arrange for the sale of such number of Vested
Earned Shares as is sufficient to generate net proceeds sufficient to satisfy the Company’s minimum statutory withholding obligations with respect to the income recognized by the Recipient upon the vesting of the Award Shares (based on minimum
statutory withholding rates for all tax purposes, including payroll and social security taxes, that are applicable to such income), and the Company shall retain such net proceeds in satisfaction of such tax withholding obligations. 

(b) The Recipient hereby appoints the Chief Executive Officer, Chief Financial Officer, Chief Administrative Officer and Chief Legal Officer of
the Company, and either of them acting alone and with full power of substitution, to serve as his or her attorneys in fact to sell the Recipient’s Common Stock in accordance with this Exhibit D. The Recipient agrees to execute and deliver such
documents, instruments and certificates as may reasonably be required in connection with the sale of the shares of Common Stock pursuant to this Exhibit D. 

(c) The Recipient represents to the Company that, as of the date hereof, he or she is not aware of any material nonpublic information about the
Company or the Common Stock. The Recipient and the Company have structured this Agreement, including this Exhibit D, to constitute a “binding contract” relating to the sale of Common Stock, consistent with the affirmative defense to
liability under Section 10(b) of the Securities Exchange Act of 1934 under Rule 10b5-1(c) promulgated under such Act. 
 The Company
take any of the actions described in Section 5(b) with respect to any Vested Earned Shares until it is satisfied that all required withholdings have been made.

 SCHEDULE “1” 

CERTAIN DEFINED TERMS 

“ACM” shall mean and refer to asbestos, asbestos-containing materials or presumed asbestos-containing materials. 

“Additional Rent” shall mean and refer to all amounts (other than Base Rent) payable by Tenant to Landlord pursuant to this Lease, whether or
not denominated as such. 
 “Affiliate Transfer” shall mean and refer to an assignment by Tenant of this Lease to a Tenant Affiliate where

	 4. Effective Date/

Commencement Date:
	  	 
	 	 
	 (a) Effective Date:
	  	December 31, 2010, being the latest of the parties’ respective dates of execution of this Lease, as set forth on the signature page of this Lease (and which date
shall be inserted in this Item 4 by Landlord, upon Landlord’s counter-execution of this Lease.)
	 	 
	 (b) Target
	  	 
	 Commencement Date:
	  	May 1, 2011.
	 	 
	 (c) Early Delivery Date:
	  	April 1, 2011
	 	 
	 (d) Outside Completion

Date:
	  	June 30, 2011
	 	 
	 (e) Commencement Date:
	  	 Subject to the terms of Section 2.2.4 of the Standard Lease Provisions, the date
upon which Landlord has completed the Commencement Date Conditions.
  

	5. Term:	  	 Approximately
seventy-two (72) full calendar months (i.e., commencing on the Commencement Date and expiring on the last day of the seventy-second (72nd) full calendar month thereafter).
  

For the avoidance of doubt, Landlord and Tenant acknowledge and agree that, if the Commencement Date occurs on a date that is other than the first (1st) day of a calendar month, the Term of this Lease shall be deemed to have been automatically extended by the number of calendar days in the Partial Month, such that the Term of the Lease shall then
be equal to the number of full calendar months described above, plus the number of calendar days in the Partial Month.
  

For example:
  

a. If the Commencement Date occurs on May 1, 2011, then the seventy-two (72) full calendar month Term of
this Lease would commence on May 1, 2011, and expire on April 30, 2017.
  

b. If, however, the Commencement Date occurs on May 18, 2011, then the seventy-two (72) full calendar
month Term of this Lease would commence on May 18, 2011, and expire on May 31, 2017. In this example, the period occurring from May 18, 2011 through May 31, 2011 is the
Partial Month. The Base Rent payable by Tenant hereunder during such Partial Month shall be payable by Tenant on a pro-rated basis, in accordance with Section 3.1 of the Standard Lease Provisions, at a rate equal to the rate of Base Rent that would
otherwise be due and payable by Tenant hereunder with regard to the first (1st) month of the Term of this Lease (pro-rated on a per diem basis). However, in this example, the first (1st) month of the seventy-two (72) full calendar month Term of this Lease would, for the purposes of calculating the expiration of the Term of the Lease, be deemed to be the month of
June, 2011.

  
 -ii- 

			
	 6. Extension Options/

Extension Term:
  
	  	 Two (2) Extension
Options, each to extend the Term for an Extension Term of forty-eight (48) months, subject to the terms of Section 2.3, below.
  

	 7.

term “Tenant Space” shall mean and refer to Premises-A, Premises-B and the Pathway.

1.6 Common Area. The Common Area shall be subject to Landlord’s sole management and control and shall be operated and maintained
in such manner as Landlord in Landlord’s discretion shall determine, subject to the rights of Tenant under this Lease and provided that Landlord will not take any actions with respect to such Common Area that will unreasonably interfere with
Tenant’s access to the Tenant Space or the use of the Tenant Space 

  
 -1- 

 
for the Permitted Use. Tenant, and the other Tenant Parties, shall have the nonexclusive right to use the Common Area as constituted from time to time; such use to be in common with Landlord, the
other members of the Landlord Group, other tenants of the Building and other persons entitled to use the same, and subject to such reasonable rules and regulations governing use of the Common Areas as Landlord may from time to time prescribe
provided that written notice of such rules and regulations is provided to Tenant. Landlord may temporarily close any part of the Common Area for such periods of time as may be necessary to prevent the public from obtaining prescriptive rights or to
make repairs or alterations. 
  

	2.	TERM. 

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

2.2 Delivery of Tenant Space. Landlord shall use commercially reasonable efforts to satisfy the Commencement Date Conditions and
deliver Premises-A and the Pathway to Tenant on or prior to the Target Commencement Date. Once and if Landlord completes the Commencement Date Conditions, Landlord and Tenant acknowledge and agree that, by virtue of Landlord’s delivery of the
Commencement Date Notice to Tenant, Landlord shall be deemed to have delivered Premises-A and the Pathway to Tenant, and Tenant shall be deemed to have accepted the same. 

2.2.1 Landlord and Tenant agree that, if the Commencement Date Conditions have occurred prior to the Target Commencement Date, Landlord shall
have the right to deliver the Commencement Date Notice to Tenant, and thereby cause the Commencement Date (or the Deemed Commencement Date, pursuant to Section 2.2.4, below) to occur, on or after the Early Delivery Date, provided that Landlord
will use commercially reasonable efforts to deliver the notice of the Early Delivery Date at least ten (10) days prior to the Early Delivery Date. 

2.2.2 In the event that the Commencement Date Conditions have not been completed by the Target Commencement Date, subject to extension by
virtue of Tenant Delay* and Force Majeure*, Landlord shall not be deemed in default hereunder, and the Commencement Date shall be postponed, as Tenant’s sole and exclusive remedy, until the date on which the Commencement Date Conditions have
occurred. Notwithstanding the foregoing, in the event that Commencement Date Conditions have not occurred prior to the Outside Completion Date, subject to extension by virtue of Tenant Delay* and Force Majeure*, Tenant shall have the right, as its
sole and exclusive remedy, to terminate this Lease, provided that (a) Tenant notifies Landlord of such termination prior to the earlier to occur of (1) completion of the Commencement Date Conditions; or (2) no later than ten
(10) days after the Outside Completion Date; and (b) Landlord has not caused the Commencement Date Conditions to have been completed within five (5) days after its receipt of such notice of termination from Tenant. If (aa) the
Commencement Date Conditions are completed prior to Tenant’s exercise of the foregoing termination right, (bb) the Commencement Date Conditions are completed within five (5) days after Tenant’s exercise of the foregoing termination
right, or (cc) Tenant shall fail to exercise such termination right within ten (10) days after the Outside Completion Date, then such termination right shall, in any such event, be deemed to have expired and shall, thereafter, be of no further
force or effect. 
  

	*	Landlord agrees to use commercially reasonable efforts to provide notice to Tenant of the occurrence of such a delay reasonably contemporaneously with such occurrence. Additionally, Landlord and Tenant agree that
extensions of the Target Commencement Date and the Outside Completion Date by Force Majeure shall be capped at an aggregate of one hundred (100) days of such delays. 

2.2.3 Intentionally Deleted. 

  
 -2- 

 2.2.4 Tenant agrees that, if the date of Landlord’s completion of the Commencement Date
Conditions is, in effect, pushed back due to delays caused by Tenant Delay*, the Commencement Date shall, upon delivery of the Commencement Date Notice, be deemed (for the purpose of determining the first day of the Term and the first day of Rent
accrual hereunder) to have been moved up to the Deemed Commencement Date. The foregoing notwithstanding, Landlord and Tenant agree that Landlord’s post-Commencement Date obligations hereunder shall, in the event of a Deemed Commencement Date,
be deemed to have commenced as of the actual date that the Commencement Date Notice is delivered to Tenant. 
  

	*	Landlord agrees to use commercially reasonable efforts to provide notice to Tenant of the occurrence of such a delay reasonably contemporaneously with such occurrence. 

2.2.5 Delivery of Premises-B. Landlord and Tenant acknowledge and agree that, on the Phase II Expansion Date, Landlord shall be deemed
to have delivered Premises-B to Tenant, and Tenant shall be deemed to have accepted the same. For the avoidance of doubt (and notwithstanding the fact that Premises-A and Premises-B are (or will be) constructed as one combined cage), Landlord and
Tenant acknowledge and agree that Tenant shall have no right to occupy or use Premises-B (or any of the equipment or electrical power located in, provided to and/or serving such space, as applicable), until the occurrence of the Phase II Expansion
Date. 
 2.3 Extension Options. 

2.3.1 Subject to and in accordance with the terms and conditions of this Section 2.3, Tenant shall have the number of Extension Options
specified in Item 6 of the Basic Lease Information to extend the Term of this Lease, for the respective Extension Terms specified in such Item 6, upon the same terms, conditions and provisions applicable to the then-current Term of this

2.3.2 Tenant may exercise each Extension Option only by delivering an Extension Option Exercise Notice to Landlord at least six
(6) calendar months prior to the then applicable expiration date of the Term, specifying that Tenant is irrevocably exercising its Extension Option so as to extend the Term of this Lease by an Extension Term on the terms set forth in this
Section 2.3. In the event that Tenant shall duly exercise an Extension Option, the Term shall be extended to include the applicable Extension Term (and all references to the Term in this Lease shall be deemed to refer to the Term specified in
Item 5 of the Basic Lease Information, plus all duly exercised Extension Terms). In the event that Tenant shall fail to deliver an Extension Option Exercise Notice within the applicable time period specified herein for the delivery thereof,
time being of the essence, at the election of Landlord, Tenant shall be deemed to have forever waived and relinquished such Extension Option, and any other options or rights to renew or extend the Term effective after the then applicable expiration
date of the Term shall terminate and shall be of no further force or effect. 
 2.3.3 Tenant shall have the right to exercise any Extension
Option only with respect to the entire Tenant Space leased by Tenant at the time that Tenant delivers the applicable Extension Option Exercise Notice. If Tenant duly exercises an Extension Option, Landlord and

  
 -3- 

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

	3.	BASE RENT AND OTHER CHARGES. 

 3.1 Base Rent. Tenant shall pay Base Rent to
Landlord throughout the Term of this Lease. All Base Rent shall be paid to Landlord in monthly installments in advance on the first day of each and every calendar month throughout the Term of this Lease; provided, however, that (a) the
installment of Base Rent for the first (1st) full calendar month of the Term shall be payable upon Tenant’s execution of this Lease; and (b) if the Term of this Lease does not
commence on the first day of a calendar month, the Base Rent for the Partial Month shall (i) be calculated on a per diem basis determined by dividing the Base Rent above by the total number of calendar days in such Partial Month and multiplying
such amount by the number of days remaining in such Partial Month from and after (and including) the Commencement Date, and (ii) be paid by Tenant to Landlord on the Commencement Date. Except as set forth in this Section 3.1, Tenant shall
not pay any installment of Rent more than one (1) month in advance. 
 3.2 Installation Fee. Tenant shall pay the Installation
Fee to Landlord, no later than the thirtieth (30th) day following receipt of an invoice therefor. Landlord and Tenant acknowledge that the Installation Fee represents partial remuneration to
Landlord in consideration of the costs incurred by Landlord in connection with Landlord’s Installations and otherwise in connection with Landlord’s fixturization of the Tenant Space related to this Lease. 

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

  
 -4- 

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

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

3.5 Utilities. Tenant shall pay for all electricity and/or other utilities (e.g., chilled water) serving, provided to and/or used in,
or for, the Tenant Space. Tenant shall pay each Tenant’s Utility Payment to Landlord, as Additional Rent, within thirty (30) days of receipt of each Tenant’s Utility Payment invoice. The formula described in Section 3.5.1, below,
has been designed to capture Tenant’s Shared Mechanical Payment. Additionally, in the event that Landlord determines that it is no longer commercially impractical to separately meter some or all of the utility costs related to some or all of
the Shared Mechanical Equipment, then Landlord may, at Landlord’s sole cost and expense, cause the relevant Shared Mechanical Equipment to be separately metered to the Tenant Space. In such event, Tenant’s Utility Payment related to the
newly metered Shared Mechanical Equipment shall thereafter be the separately metered cost of the shared utilities provided to, serving and/or used in, the Tenant Space by such equipment based upon the Shared Mechanical Metering Equipment (i.e., such
payment would then be a Tenant’s Separately Metered Utility Payment). Landlord and Tenant acknowledge and agree that the utility costs for which Tenant shall be responsible include the actual cost of all utilities (including electricity)
serving, provided to and/or used in the UPS Room and the Pump Room. For the avoidance of doubt, it is the intent of the parties that this Section 3.5 represents a mechanism only for Landlord’s cost recovery with regard to utilities
(including electrical power) serving, provided to and/or used in or for the Tenant Space, and that there is no intent for Tenant’s Utility Payment to include any element of profit to Landlord in connection therewith. 

3.5.1 Calculation of Tenant’s Datacenter Utility Payments. 

3.5.1.1 During Periods of Premises Operation, the term Tenant’s Datacenter Utility Payment, as it relates to each
Datacenter Utility Bill, shall mean the result of the following formula: 
 G = N x (A / B) 

  
 -5- 

 3.5.1.2 Intentionally Deleted. 

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

3.5.3 Generator Fuel Usage. Additionally, Tenant shall pay the cost of all Generator Fuel Usage, except for the extent to which such
Generator Fuel Usage represents Maintenance Fuel Usage or results from the gross negligence or willful misconduct of Landlord. Landlord shall bill Tenant not more frequently than monthly for the amount of the Generator Fuel Payment. Tenant shall pay
the Generator Fuel Payment to Landlord, as Additional Rent, within thirty (30) days of delivery of each Generator Fuel Payment invoice. For the avoidance of doubt, it is the intent of the parties that this Section 3.5.3 represents a
mechanism only for Landlord’s cost recovery with regard to non-maintenance related Generator Fuel Usage, and that there is no intent for Tenant’s Generator Fuel Payment to include any element of profit to Landlord in connection therewith.

 3.5.4 Tenant’s Additional Rent Audit Right. Landlord shall keep complete books and records regarding all Additional Rent
charges made by Landlord hereunder. All such records pertaining to a particular calendar year shall be retained for at least one (1) full calendar year after the expiration of such particular calendar year (i.e., all such records pertaining to
the calendar year 2012 shall be retained at least until the end of the calendar 2013). Tenant shall have the right, once per twelve (12) month period during the Term, to audit the applicable Additional Rent records of Landlord to confirm that
the Additional Rent charges billed to Tenant conform to the provisions of this Lease. Such right, as it relates to any calendar year, shall be exercisable by Tenant within one (1) year after the expiration of such calendar year. Landlord shall
cooperate with Tenant during each such audit in providing Tenant reasonable access to Landlord’s books and records for the calculation of such items of Additional Rent during normal business hours to enable Tenant to audit such books and
records. If the audit discloses any overpayment on the part of Tenant, then Tenant shall be entitled to a credit on the next succeeding installment of Additional Rent, following Landlord’s confirmation of the correctness of such audit
conclusions, for an amount equal to the overcharge, and such credit shall be extended to succeeding installments of Additional Rent in the event such overcharge exceeds the amount of the next succeeding such installment. In the event the Term of
this Lease has expired or been earlier terminated, then Tenant shall be entitled to a refund of such excess from Landlord within thirty (30) days after Landlord’s confirmation of the correctness of such audit conclusions. In addition, in
the event such audit by Tenant discloses such an overcharge in excess of ten percent (10%) of the amount payable pursuant to this Lease, then Landlord shall pay to Tenant the reasonable costs and expenses of such audit, not to exceed Five
Thousand and No/100 Dollars ($5,000.00) for any particular audit. 
  

	4.	TAXES. 

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

  
 -6- 

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

	5.	INTENTIONALLY DELETED. 

  

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

 6.1 Permitted

discretion. 
 6.1.1 Limitations on Permitted Use. Tenant agrees that neither Tenant, nor any other Tenant Party, may use the Tenant
Space, or operate within the Tenant Space, the Datacenter and/or the Building, in any manner, which: (i) causes or is reasonably likely to cause damage to the Property, the Building, the Datacenter, the Tenant Space or any Building System;
(ii) will invalidate or otherwise violate a requirement or condition of any fire, extended coverage or any other insurance policy covering the Property, the Building, and/or the Tenant Space, or the property located therein, or will increase

facilities or systems of any such tenant or occupant; (iv) unreasonably and materially interferes with the transmission or reception of microwave, television, radio, telephone, or other communication signals by antennas or other facilities

other portion of the Building, (b) provide MMR Services in the Tenant Space or any other portion of the Building, or (c) refer to the Tenant Space as a “meet-me room”. Tenant agrees to reimburse Landlord for any losses, costs or
damages caused by unauthorized parties who gain access to the Tenant Space or the Building through access cards, keys or other access devices provided to Tenant (or any other Tenant Party) by Landlord. Tenant agrees to reimburse Landlord, as
Additional Rent, for any additional insurance premium charged by Landlord’s insurance carrier for any insurance policy by reason of Tenant’s failure to comply with the provisions of this Section 6.1.1. 

6.2 Datacenter Rules and Regulations. Tenant’s Permitted Use shall be subject to, and Tenant, and all other Tenant Parties, shall
comply fully with the Datacenter Rules and Regulations. Landlord shall have the right, from time-to-time, to change, amend and/or supplement the Datacenter Rules and Regulations as may be deemed by Landlord, in the exercise of its sole but good
faith discretion, advisable for the safety, care and/or cleanliness of the Tenant Space, the Datacenter, the Building and/or the Property, and/or for the preservation of good order in any of same; provided, however, that such changes to the
Datacenter Rules and Regulations may not increase Tenant’s monetary obligations under this Lease or unreasonably interfere with Tenant’s Permitted Use of the Tenant Space. In the event of a conflict between the Datacenter Rules and
Regulations and the terms of this Lease, the terms of this Lease shall govern. Tenant shall be responsible for causing the other Tenant Parties to comply with the Datacenter Rules and Regulations. Landlord shall notify Tenant in writing when changes
are made to Datacenter Rules and Regulations. 
 6.3 Compliance with Laws; Hazardous Materials. 

6.3.1 Compliance with Laws. Tenant, at Tenant’s sole cost and expense, shall timely take all action required to cause all

 -7- 

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

6.3.1.2 Except for the extent of Tenant’s obligations with regard to compliance with Applicable Laws set forth in Section 6.3.1,
above, Landlord covenants to timely take all action required to cause the Building and the Premises to be in material compliance with all Applicable Laws, including the requirements of all applicable easement and encumbrance documents throughout the
Term. 
 6.3.2 Hazardous Materials. Tenant agrees that neither Tenant, nor any other Tenant Party, shall Handle any Hazardous
Materials in the Tenant Space or any portion of the Building or the Property. Additionally, Tenant agrees that neither Tenant, nor any other Tenant Party, shall use the Tenant Space in any manner which may directly or indirectly lead to any
non-compliance with any Environmental Law. 
 6.3.2.1 Landlord hereby represents and warrants to Tenant that, to the best of
Landlord’s Actual Knowledge, as of the Effective Date, (a) except for the extent to which same is disclosed in the Environmental Reports, neither the Property, nor the Building nor the Tenant Space contain any Hazardous Materials, other

remediation costs, and other expenses actually incurred by Tenant as a result of the presence of any Hazardous Materials in, on, about, under or emanating from the Premises or Property as of the Effective Date of this Lease. 

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

	7.	ACCESS CONTROL; LANDLORD’S ESSENTIAL SERVICES; INTERRUPTION OF SERVICES; SAS 70. 

7.1 Access Control. Landlord will provide Landlord’s Access Control Systems during the Term of this Lease. Landlord reserves the
right, but without assuming any duty, to institute additional access control measures in order to further control and regulate access to the Building or any part thereof. Landlord shall not, under any circumstances, be responsible for providing or
supplying security services to the Datacenter, the Tenant Space or any part of the Building in excess of the Landlord’s Access Control Systems (and, unless expressly agreed in writing by Landlord, Landlord shall not under any circumstances be
deemed to have agreed to provide any access control services in excess of the above specified Landlord’s Access Control Systems). Tenant acknowledges and agrees that the activities of all persons in the Datacenter are and shall be
subject to surveillance by video camera and/or otherwise by Landlord’s agents and employees. 
 7.1.1 In connection with
Landlord’s Access Control Systems, Landlord agrees to maintain an authorized “access list” for the Tenant. Landlord agrees to use commercially reasonable efforts to perform “adds to” and “removals from” such
authorized “access list” within one (1) hour after receiving any written notice of such request that is provided between the hours of 8:00am and 5:00pm on business days.

except as expressly set forth on Exhibit “F”, attached hereto, with regard to Interruptions of Essential Services, no interruption or malfunction of any electrical or other service to the Premises, or to any other portion of

reasonable efforts to restore such service or cause the same to be restored in any circumstances in which such restoration is within the reasonable control of Landlord. 

7.4 SAS-70 Reporting. Landlord agrees to reasonably cooperate with Tenant, at no cost to Tenant, in regards to Tenant’s conduct of
any audit of (a) Tenant’s operations in the Tenant Space and/or (b) the maintenance and operation of the Building, performed in accordance Statement on Auditing Standards Number 70, as promulgated by the American Institute of

report that Landlord receives as a result of each such SAS 70 Audit, except that Landlord shall be permitted to redact from each such report any information that relates to (i) any premises in the Building other than the Premises; and/or
(ii) any tenant in the Building other than Tenant. 
 7.5 Self-Help Restriction. Landlord and Tenant acknowledge and agree that,
due to the “shared” nature of the Datacenter and the electrical and mechanical infrastructure serving same, Tenant shall not have the right to perform any of Landlord’s maintenance and/or repair obligations under

	8.	MAINTENANCE; ALTERATIONS; REMOVAL OF TENANT’S PERSONAL PROPERTY. 

 8.1
Landlord’s Maintenance. Except as expressly provided in this Section 8.1, Landlord shall have no obligation to repair and/or maintain the Tenant Space. Landlord will maintain and keep in good repair at Landlord’s sole cost and
expense the Pathway, the PDUs serving the Premises, Landlord’s Access Control Systems, the HVAC system and plumbing, if any, serving the Premises, the UPS Plant serving the Premises, the Back-Up Power, the fire suppression systems serving the

which Tenant wishes to inspect the PM Books and Records. Any such PM Audit shall be performed during Landlord’s normal business hours at a time and location within the Building reasonably designated by Landlord. Landlord shall respond to
Tenant’s PM Audit Notice within five (5) business days after Landlord’s receipt of Tenant’s PM Audit Notice with the date, time and location of Tenant’s PM Audit. If Tenant’s PM Audit reveals that Landlord is delinquent
in complying with the PM Schedule, Tenant shall deliver written notice to Landlord of such delinquency, and Landlord shall cure such delinquency within the time allowed pursuant to Section 16.1.1 of this Lease. 

  
 -10- 

 8.2 Tenant’s Maintenance. During the Term of this Lease, Tenant shall, at
Tenant’s sole cost and expense, maintain the Tenant Space and Tenant’s equipment therein in good order and in a clean and safe condition. If Tenant fails to perform its covenants of maintenance and repair hereunder, or if Tenant or any of
Tenant’s technicians or representatives physically damages the Property, the Building or any portion of any of the above, or the personal property of any other tenant or occupant, or causes an interruption of services to the Premises, the
Datacenter and/or in the Building, Landlord may, but shall not be obligated to, perform all necessary or appropriate maintenance and repair, and any amounts expended by Landlord in connection therewith, plus an administrative charge of ten percent
(10%) of such amounts, shall be reimbursed by Tenant to Landlord as Additional Rent within thirty (30) days after Landlord’s demand therefor. 

8.3 Alterations. 
 8.3.1
Notwithstanding any provision in this Lease to the contrary, Tenant shall not make or cause to be made any Alterations to the Tenant Space, the Datacenter, or any other portion of the Building or Property without the prior written consent and
approval of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed. The foregoing notwithstanding, Landlord’s consent shall not be required for any usual and customary installations, repairs, maintenance, and
removals of electrical distribution equipment downstream of the PDUs in the Premises, equipment and telecommunication cables within the Tenant Space if and to the extent that such installations, repairs, maintenance, and removals (i) are usual
and customary within the industry, (ii) are in compliance with the Datacenter Rules and Regulations, and (iii) will not adversely affect the Building’s structure, the provision of services to other Building tenants, or the
Building’s electrical, plumbing, HVAC, life safety or mechanical systems. Landlord and Tenant acknowledge and agree that (a) Landlord’s Installations are hereby deemed to be Alterations hereunder; and (b) all Landlord’s
Installations shall be left as part of the Tenant Space, upon the expiration or earlier termination of this Lease, in good and operable condition, ordinary wear and tear and damage by fire or other casualty excepted. 

8.3.2 Each request for Alterations consent must contain one (1) full size hard copy of all drawings together with one (1) full set
of drawings on CD. 
 8.3.3 In any instance where Tenant desires to conduct Alterations, Tenant’s contractors, laborers, material men
and others furnishing labor or materials for Tenant’s job must work in harmony, and not interfere, with any labor utilized by Landlord, Landlord’s contractors or mechanics or by any other tenant or such other tenant’s contractors or
mechanics; and if at any time such entry by one (1) or more persons furnishing labor or materials for Tenant’s work shall cause disharmony or interference for any reason whatsoever without regard to fault, the consent granted by Landlord
to Tenant and/or the express or implied permission for such persons to enter the Premises may be withdrawn at any time upon written notice to Tenant. Additionally, all such contractors, laborers, material men and others must obtain (and provide
Landlord evidence of) such insurance as Landlord may reasonably require, prior to any such entry; provided that, in no event shall such insurance requirements exceed those that are described on Exhibit “B-1”, attached hereto. 

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

 9.1 Casualty Events; Takings. 

9.1.1 Casualty Events. If, during the Term of this Lease, any portion of the Building, the Datacenter, or the Tenant Space shall be
damaged or destroyed, in whole or in part, by a Casualty Event, Landlord shall, subject to the terms of this Section 9.1.1, and Sections 9.1.1.1 and 9.1.1.2, below, cause the Casualty Repair to occur. Landlord shall provide the Casualty Repair
Notice to Tenant as soon as is reasonably practicable following the Casualty Event. For the avoidance of doubt, however, such repair and reconstruction obligation shall not be deemed to include any obligation on the part of Landlord with regard to
any Alteration other than Landlord’s Installations, nor any of Tenant’s Personal Property. 
 9.1.1.1 Landlord’s
Termination Right. Notwithstanding the foregoing, in the event that the Repair Period-Estimated exceeds ninety (90) days, Landlord shall have the right to terminate this Lease by, and effective upon, written notice to Tenant as part of the
Casualty Repair Notice. 
 9.1.1.2 Tenant’s Termination Right. If (a) a Casualty Event causes damage to the Tenant Space,
or (b) a Casualty Event causes damage to the Building, such that Tenant is prevented from accessing the Premises or Tenant’s use of the Premises/Pathway for the Permitted Use is materially impaired, then Tenant shall have the right to
terminate this Lease by, and effective upon, written notice to Landlord if (i) the Repair Period-Estimated exceeds ninety (90) days (in which case Tenant must provide written notice to Landlord of such termination within sixty
(60) days after Tenant’s receipt of the Casualty Repair Notice), or (ii) the Repair Period-Actual exceeds ninety (90) days (in which case Tenant must provide written notice to Landlord of such termination prior to the one
hundredth (100th) day of the Repair Period-Actual). 
 9.1.1.3
Casualty-Complete. The foregoing notwithstanding, in the event of a Casualty-Complete, this Lease shall automatically terminate as of the date of the Casualty-Complete. 

9.1.1.4 Base Rent Abatement – Casualty Events. In the event that this Lease is terminated pursuant to Sections 9.1.1.1, 9.1.1.2
or 9.1.1.3, above, Landlord shall refund to Tenant any prepaid Base Rent, less any sum then owing to Landlord by Tenant. If, however, this Lease is not terminated pursuant to any of said Sections, Base Rent shall be abated proportionately during the
Repair Period-Actual to the extent that the Tenant Space (i) is unfit for use by Tenant in the ordinary conduct of Tenant’s business, and (ii) actually is not used by Tenant. 

9.1.2 Takings. 
 9.1.2.1
Total Taking. If all or substantially all of the Tenant Space, the Building or the Property shall be the subject of a Taking, this Lease shall terminate as of the date of the vesting of title in the condemning authority. 

9.1.2.2 Partial Taking. If only a part of the Tenant Space, the Building or the Property shall be the subject of a Taking, this Lease
shall continue in full force and effect, subject to the terms of Sections 9.1.2.3-9.1.2.7, below. 
 9.1.2.3 Landlord’s Termination
Right – Partial Taking. If the part of the Building or the Property that is taken or condemned as part of the Taking contains a part of the Tenant Space, the Building or the Property that, in Landlord’s reasonable discretion, is
material to the operation of the Tenant Space, Landlord may terminate this Lease by notice to Tenant given within sixty (60) days following the date upon which Landlord received notice of such Taking. If Landlord so notifies Tenant, this Lease
shall terminate upon the date set forth in the notice, which date shall not be more than thirty (30) days following the giving of such notice. 

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

  
 -12- 

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

9.1.2.6 Base Rent Abatement – Taking. In the event that this Lease is terminated pursuant to Sections 9.1.2.1, 9.1.2.3 or
9.1.2.4, above, Landlord shall refund to Tenant any prepaid Base Rent, less any sum then owing to Landlord by Tenant. If, however, this Lease is not terminated pursuant to any of said Sections, Base Rent shall be reduced proportionately to the
extent that the Premises is reduced as a result of the Taking. 
 9.1.2.7 Taking Award Rights. Landlord reserves the right to
receive the entirety of the condemning authority’s award related to a Taking of any portion of the Property. The foregoing notwithstanding, in the event that this Lease is terminated in connection with any Taking, Landlord expressly permits
Tenant to make a separate claim against the condemning authority, in any appropriate proceeding, for the value of Tenant’s unamortized, but taken, leasehold improvements or other improvements to the Tenant Space made by Tenant and for
Tenant’s moving expenses related to such Taking, but only if such claim and/or recovery does not reduce the condemnation/taking award otherwise payable to Landlord in connection with such Taking. If any such award that is made, or compensation
that is paid, to either party specifically includes an award or amount for the other, the party first receiving the same shall promptly make an accounting of same to the other. 

9.1.3 Tenant’s Remedy. Tenant’s termination rights and rights to Base Rent abatement, to the extent provided above in this
Article 9, shall be Tenant’s sole and exclusive remedies in the event of a Casualty Event or Taking. 
 9.2 Tenant’s
Insurance. Tenant shall, at Tenant’s expense, procure and maintain throughout the Term of this Lease a policy or policies of insurance in accordance with the terms and requirements set forth in Exhibit “B-1” to this Lease.
All of Tenant’s insurance policies with respect to the Tenant Space shall be endorsed so as to include a waiver of subrogation in accordance with and to the full extent of Tenant’s waiver of claims with respect to the Landlord Group set
forth in Section 14.1.1 of this Lease. 
 9.2.1 The commercial general liability policies procured by Tenant hereunder shall name
Landlord and Landlord’s managing agent, and any Holders designated by Landlord as additional insureds. Prior to occupying the Tenant Space, and prior to the expiration of each such policy, Tenant shall submit to Landlord certificates of
insurance evidencing such policies (and the applicable renewals thereof) being in effect. All insurance policies procured hereunder shall contain a provision stating that the insurer shall endeavor to provide at least thirty (30) days’
written notice to Landlord and all others named as additional insureds prior to any cancellation or material modification of such policy. 

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

 

	10.	TRANSFERS. 

 10.1 Restrictions on Transfers; Landlord’s Consent. Except as
otherwise expressly set forth in Section 10.1.1 and Section 10.5, below, to the contrary, Tenant shall not effect a Transfer, without Landlord’s express prior written consent, which consent shall not be unreasonably withheld,
conditioned or delayed. Except as 

  
 -13- 

 
otherwise expressly set forth in this Lease, no Transfer (whether voluntary, involuntary or by operation of law) shall be valid or effective without Landlord’s prior written consent and, at
Landlord’s election, any such Transfer or attempted Transfer shall constitute an Event of Default by Tenant under Section 15.1.2 of this Lease. 

10.1.1 Permitted Transfer. Notwithstanding anything to the contrary in this Lease, Tenant may, without the consent of Landlord (and
without being subject to Landlord’s recapture rights under Section 10.3, below) undertake Permitted Transfers. 
 10.2 Notice
to Landlord. If Tenant desires to make any Transfer (other than a Permitted Transfer, for which Tenant must merely notify Landlord prior to the occurrence of same), then at least ten (10) business days (but no more than one hundred eighty
(180) days) prior to the proposed effective date of the Transfer, Tenant shall submit a Transfer Notice to Landlord. If, thereafter, Tenant modifies any of the terms and conditions relevant to a proposed Transfer specified in the Transfer
Notice, Tenant agrees to re-submit such Transfer Notice to Landlord for its consent pursuant to all of the terms and conditions of this Article 10. 

10.3 Landlord’s Recapture Rights. Except with regard to a Permitted Transfer, at any time within ten (10) business days after
Landlord’s receipt of all (but not less than all) of the information and documents described in Section 10.2, Landlord shall have the right (but not the obligation), exercisable by written notice to Tenant, to elect to cancel and terminate
this Lease. 
 10.4 No Release; Subsequent Transfers. No Transfer (whether or not a Permitted Transfer) will release the undersigned
Tenant from Tenant’s obligations under this Lease or alter the primary liability of the undersigned Tenant to pay the Rent and to perform all other obligations to be performed by Tenant hereunder. In no event shall the acceptance of any payment
by Landlord from any other person be deemed to be a waiver by Landlord of any provision hereof. Consent by Landlord to one Transfer will not be deemed consent to any subsequent Transfer. In the event of breach by any Transferee in the performance of
any of the terms hereof, Landlord may proceed directly against the undersigned Tenant without the necessity of exhausting remedies against such Transferee. 

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

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

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

	12.	SUBORDINATION AND ATTORNMENT; HOLDER RIGHTS. 

 12.1 Subordination and Attornment.
Without the necessity of any additional document being executed by Tenant for the purpose of effecting a subordination, and at the election of Landlord or any Holder, this Lease will be subject and subordinate at all times to all Security Documents,
which may now exist or hereafter be 

  
 -14- 

 
executed which constitute a lien upon or affect the Property or any portion thereof, or Landlord’s interest and estate in any of said items. Notwithstanding the foregoing, Landlord reserves
the right to subordinate (or cause the subordination of) any such Security Documents to this Lease. In the event of any termination or transfer of Landlord’s estate or interest in the Property, the Building, the Datacenter or the Tenant Space
by reason of any termination or foreclosure of any such Security Documents (and notwithstanding any subordination of such Security Document to this Lease that may or may not have occurred), at the election of Landlord’s successor in interest,
Tenant agrees to attorn to and become the tenant of such successor, in which event Tenant’s right to possession of the Property will not be disturbed as long as Tenant is not in default under this Lease beyond applicable notice or cure periods.
Tenant hereby waives any right under any Applicable Law or otherwise to terminate or otherwise adversely affect this Lease and the obligations of Tenant hereunder in the event of any termination or transfer of Landlord’s estate or interest in
the Property, the Building, the Datacenter, or the Tenant Space by reason of any termination or foreclosure of any such Security Documents. Tenant covenants and agrees to execute and deliver, within fifteen (15) days of receipt thereof, and in
the form reasonably required by Landlord or any Holder, any additional documents evidencing the priority or subordination of this Lease and Tenant’s agreement to attorn with respect to any such Security Document; provided, however, any such
agreement subordinating this Lease to such lease, mortgage or deed of trust shall contain a non-disturbance provision that is reasonably acceptable to such Holder, Landlord and Tenant in accordance with Section 12.3, below. 

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

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

	13.	SURRENDER OF TENANT SPACE; HOLDING OVER. 

 13.1 Tenant’s Method of Surrender.
Upon the expiration of the Term of this Lease, or upon any earlier termination of this Lease or the termination of Tenant’s right to possess the Tenant Space, Tenant shall, subject to the provisions of this Article 13 and Section 8.4, quit
and surrender possession of the Tenant Space to Landlord in good working order and clean condition, ordinary wear and tear excepted. 
 13.2
Disposal of Tenant’s Personal Property. If any property not belonging to Landlord remains in the Tenant Space after the expiration of, or within fifteen (15) days after any earlier termination of, the Term of this Lease or the
termination of Tenant’s right to possess the Tenant Space, Tenant shall be deemed to have abandoned such property and to have authorized Landlord to make such disposition of such property as Landlord may desire without liability for
compensation or damages to Tenant or any other Tenant Party. 
 13.3 Holding Over. If Tenant should remain in possession of all or
any portion of the Tenant Space after the expiration of the Term of this Lease (or any earlier termination of this Lease or the termination of Tenant’s right to possess the Tenant Space), without the execution by Landlord and Tenant of a new
lease or an extension of the Term of this Lease, then Tenant shall be deemed to be occupying the entire Tenant Space as a tenant-at-sufferance, upon all of the terms contained herein, except as to term and Base Rent and any other provision
reasonably determined by Landlord to be inapplicable. During any such holdover period, Tenant shall pay to Landlord a monthly Base Rent in an amount equal to one hundred fifty percent (150%) of the Base Rent payable by

  
 -15- 

 
Tenant to Landlord during the last month of the Term of this Lease and one hundred percent (100%) of the Additional Rent payable by Tenant to Landlord during the last month of the Term of
this Lease. The monthly rent payable for such holdover period shall in no event be construed as a penalty or as liquidated damages for such retention of possession, nor shall such monthly rent be considered to be any form of Consequential Damages
related to such retention of possession. Neither any provision hereof nor any acceptance by Landlord of any rent after any such expiration or earlier termination shall be deemed a consent to any holdover hereunder or result in a renewal of this
Lease or an extension of the Term, or any waiver of any of Landlord’s rights or remedies with respect to such holdover. As such, and notwithstanding any provision to the contrary contained herein, Landlord expressly reserves the right to
require Tenant to surrender possession of the Tenant Space upon the expiration of the Term of this Lease or upon the earlier termination hereof or at any time during any holdover and the right to assert any remedy at law or in equity to evict Tenant
and collect damages in connection with any such holdover. 
 13.4 Survival. The provisions of this Article 13 shall survive the
expiration or early termination of this Lease. 
  

	14.	WAIVERS; INDEMNIFICATION; CONSEQUENTIAL DAMAGES; LIENS. 

 14.1 Waivers. 

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

14.2 Indemnification. 

14.2.1 Indemnification by Tenant. 

14.2.1.1 Tenant hereby agrees to indemnify, defend, and hold harmless Landlord and the other members of the Landlord Group from
and against (and to reimburse Landlord and the other members of the Landlord Group for) any and all Claims arising from and/or in connection with: 

(i) the use or occupancy of the Tenant Space or any portion of the Building or the Property by Tenant or any other Tenant Party and/or any
person claiming by, through or under Tenant or any other Tenant Party, including, without limitation: 
 (a) Claims related to any
Colocation Agreement; 
 (b) the acts or omissions of any Colocating Party; 

  
 -16- 

 (c) the payment (or non-payment) of Taxes – Equipment; 

(d) the malfunctioning of Tenant’s Security System; 

(e) Claims related to any of Tenant’s Personal Property; 

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

(g) Tenant’s failure to surrender the Tenant Space upon the expiration or any earlier termination of this Lease or the termination of
Tenant’s right to possess the Tenant Space in accordance with the terms of this Lease; and 
 (h) the removal, exercise of dominion
over and/or disposition of any of Tenant’s Personal Property that is left in the Tenant Space after the expiration of the Term of this Lease in violation of Section 13.2. 

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

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

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

 14.2.2 Indemnification by Landlord. Landlord hereby agrees to defend, indemnify, and hold harmless Tenant and the
other members of the Tenant Group from and against (and to reimburse Tenant and the other members of the Tenant Group for) all Claims to the extent arising from or in connection with the active gross negligence or willful misconduct of
Landlord or any member of the Landlord Group at the Property. 
 14.2.2.1 The foregoing notwithstanding, Landlord shall not be required to
indemnify Tenant or any other member of the Tenant Group to the extent that the relevant Claims were caused by the active gross negligence or willful misconduct of any member of the Tenant Group. 

14.2.2.2 In the event that any action or proceeding is brought against Tenant or any other member of the Tenant Group by reason of any
indemnified Claim, Landlord 

  
 -17- 

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

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

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

	15.	TENANT DEFAULT.

cured within thirty (30) days following written notice to Tenant, Tenant shall not be in default if Tenant commences to cure same within such thirty (30) day period and thereafter diligently prosecutes the curing thereof to completion.

  
 -18- 

 15.1.2.1 Event of Default-ECT Overage. Section 15.1.2, above, notwithstanding, it
shall be an Event of Default by Tenant (i) if Tenant fails to remedy* an ECT Overage within one hundred twenty (120) hours after its receipt of an ECT Default Notice, and/or (ii) if three (3) separate and distinct ECT Overages
occur in any rolling thirty (30) day period. 
  

	*	In connection with this Section 15.1.2.1, the term “remedy” shall mean and refer to a meaningful and relatively permanent remedy of the condition causing the ECT Overage.

requested to be so executed and delivered by Landlord within the time periods specified in such Article or Section, where such failure continues for ten (10) days after delivery of written notice of such failure by Landlord to Tenant. 

The parties hereto acknowledge and agree that all of the notice periods provided in this Section 15.1 are in lieu of, and not in addition
to, the notice requirements of any Applicable Laws. 
 15.2 Remedies. Upon the occurrence of any Event of Default by Tenant, Landlord
shall, in addition to an action for money damages, specific performance and/or injunctive relief, have the option to pursue any one or more of the remedies described in Section 1 of Exhibit “D” attached hereto and incorporated

	16.	LANDLORD’S LIABILITY. 

 16.1 Landlord Default; Tenant’s Remedies. 

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

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

16.1.1.2 The filing or execution or occurrence of any one of the following, provided the same is not dismissed or otherwise rectified within
sixty (60) days: (i) a petition in bankruptcy or other insolvency proceeding by or against Landlord, (ii) a petition or answer seeking relief for Landlord under any provision of the Bankruptcy Act, (iii) an assignment by Landlord

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

  
 -19- 

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

(i) the collective recourse of Tenant and its successors and assigns against Landlord (and the liability of Landlord to Tenant, its successors
and assigns) with respect to (a) any actual or alleged breach or breaches by or on the part of Landlord of any of Landlord’s Lease Undertakings, and (b) any other matter relating to Tenant’s occupancy of the Tenant Space, shall
be limited, in the aggregate, solely to an amount equal to Landlord’s Liability Cap; 
 (ii) other than Landlord’s Liability Cap,
Tenant shall have no recourse against any other assets of Landlord; 
 (iii) Tenant shall have no recourse against any assets of any member
of the Landlord Group other than Landlord; 
 (iv) except to the extent of Landlord’s Liability Cap, no personal liability or personal
responsibility of any sort with respect to any of Landlord’s Lease Undertakings, or any alleged breach thereof, is assumed by, or shall at any time be asserted or enforceable against, Landlord; and 

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

16.3 Transfer of Landlord’s Interest. Landlord (and each of Landlord’s successors-in-interest) shall have the right, from
time to time, to assign its interest and obligations, in writing and/or by operation of law, in and under this Lease to any third party to whom Landlord conveys its interest in the Property. Once and if Landlord (and/or any successor to Landlord)
shall convey its interest in the Property to a third party, (a) Landlord (and each such successor) shall be fully released from all of the obligations and liabilities of Landlord under the Lease Documents accruing on or after the date of such
transfer of Landlord’s interest in the Property to such third party, and (b) Tenant agrees to look solely to the successor-in-interest of Landlord for all such obligations and liabilities accruing on or after the date of such transfer. If
any security has been given by Tenant to secure the faithful performance of any of the covenants of this Lease, Landlord shall transfer or deliver said security, as such, to Landlord’s successor in interest and thereupon Landlord shall be
discharged from any further liability with regard to said security. 
 16.3.1 Status as a Real Estate Investment Trust. Landlord
shall have the right, from time to time, to assign part of its interest and obligations in and under this Lease to a wholly owned subsidiary of Landlord (or a wholly owned subsidiary of Landlord’s parent company), if and to the extent that
Landlord determines such partial transfer is necessary or advisable in connection with the status of Landlord, or any other member of the Landlord Group, as a real estate investment trust. 

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

 

	17.	MISCELLANEOUS. 

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

  
 -20- 

 17.2 No Waiver. No failure or delay by Landlord to insist on the strict performance of any
obligation, covenant, agreement, term or condition of this Lease, or to exercise any right or remedy available upon such non-performance, will constitute a waiver thereof, and no breach or failure by Tenant to perform will be waived, altered or
modified, except by written instrument signed by Landlord. 
 17.3 Attorneys’ Fees and Costs. If either Landlord or Tenant
initiates any litigation, mediation, arbitration or other proceeding regarding the enforcement, construction or interpretation of this Lease, then the non-prevailing party shall pay the prevailing party’s reasonable attorneys’ fees and

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

17.4 Waiver of Right to Jury Trial. TO THE FULLEST EXTENT PERMITTED BY LAW, LANDLORD AND TENANT EACH EXPRESSLY WAIVES ITS RIGHT TO
TRIAL BY JURY IN ANY TRIAL HELD AS A RESULT OF A CLAIM ARISING OUT OF, IN CONNECTION WITH, OR IN ANY MANNER RELATED TO THIS LEASE IN WHICH LANDLORD AND TENANT ARE ADVERSE PARTIES. FOR THE AVOIDANCE OF DOUBT, THE FILING OF A CROSS-COMPLAINT BY ONE
AGAINST THE OTHER IS SUFFICIENT TO MAKE THE PARTIES “ADVERSE.” 
 17.5 Headings; Time; Survival. The headings of the
Articles, Sections, Schedules and Exhibits of this Lease are for convenience only and do not define, limit or construe the contents thereof. Words of any gender used in this Lease shall be held and construed to include any other gender, and words in

that time is of the essence. Any obligations of a party accruing prior to the expiration or termination of this Lease shall survive the expiration or termination of this Lease, and such party shall promptly perform all such obligations whether or
not this Lease has expired.

writing and may be delivered by (i) hand delivery or personal service, (ii) a reputable overnight courier service which provides evidence of delivery, or (iii) (iv) e-mail (so long as a confirming copy is forwarded by a reputable

of the Basic Lease Information, or at such other addresses as either party may have theretofore specified by written notice delivered in accordance herewith. Such address may be changed from time to time by either party by giving notice as provided
herein. Notice shall be deemed given, (a) when delivered (if delivered by hand or personal service), (b) if sent by a reputable overnight courier service, on the business day immediately following the business day on which it was sent, or
(c) the date the e-mail is transmitted. 
 17.7 Governing Law; Jurisdiction. This Lease shall be governed by, and construed in
accordance with, the laws of the state in which the Property is located. In addition, Landlord and Tenant hereby submit to the local jurisdiction of the State in which the Property is located. Each party agrees that any action by the other against
such party shall be instituted in the State in which the Property is located. 
 17.8 Incorporation; Amendment; Merger. This Lease,
along with any schedules, exhibits and attachments or other documents referred to herein, all of which are hereby incorporated into this Lease by this reference, constitutes the entire and exclusive agreement between Landlord and Tenant relating to

with the meaning of its terms and the intent of the parties. This Lease shall not be binding or effective until each of the parties hereto has executed and delivered an original counterpart hereof to each other. No contractual or other rights shall
exist between Landlord and Tenant with respect to the Tenant Space until both have executed and delivered this Lease, notwithstanding that Landlord has delivered to Tenant an unexecuted copy of this Lease. The submission of this Lease to Tenant
shall not constitute the grant of an option for the Tenant to lease, or otherwise create any interest by Tenant in, the Tenant Space. The execution of this Lease by Tenant and return to Landlord shall not be binding upon Landlord, notwithstanding
any time interval, until Landlord has, in fact, executed and delivered this Lease to Tenant.

obligations that may be cured by the payment of money (e.g., maintaining insurance)) if such failure is caused by a Force Majeure event. The amount of time for a party to perform any of its obligations (other than payment obligations) shall be
extended by the amount of time such party is delayed in performing such obligation by reason of any Force Majeure event. 
 17.15 No
Partnership or Joint Venture; No Third Party Beneficiaries. Nothing contained in this Lease shall be deemed or construed to create the relationship of principal and agent, or partnership, or joint venturer, or any other relationship between
Landlord and Tenant other than landlord and tenant. Landlord shall have no obligations hereunder to any person or entity other than Tenant, and no other parties shall have any rights hereunder as against Landlord. 

17.16 Access by Landlord. Landlord, Landlord’s agents and employees shall have the right to enter upon any and all parts of the

Landlord’s rights hereunder, Tenant agrees that Landlord shall at all times have and retain a key that will unlock all of the doors in, on or about the Tenant Space; and, in the absence of such a key, Landlord shall have the right to use any
reasonable means to open such doors to obtain entry to the Tenant Space. Notwithstanding anything herein to the contrary, except for emergencies, Landlord shall use reasonable efforts to minimize disruption of Tenant’s business or occupancy
during such entries.

Counterparts; Delivery by Facsimile or E-mail. This Lease may be executed simultaneously in two or more counterparts each of which shall be deemed an original, but all of which shall constitute one and the same Lease. Landlord and Tenant
agree that the delivery of an executed copy of this Lease by facsimile or e-mail shall be legal and binding and shall have the same full force and effect as if an original executed copy of this Lease had been delivered. 

17.19 Confidentiality. Each party agrees that (i) the terms and provisions of this Lease, business and financial information
disclosed by either party, trade secrets, and disputes, are confidential and constitute proprietary information of the parties and (ii) it shall not disclose, and it shall cause its partners, officers, directors, shareholders, employees,
brokers and attorneys to not disclose any term or provision of this Lease to any other person without first obtaining the prior written consent of the other party, except that each party shall have the right to disclose such information for valid
business, legal and accounting purposes and/or if advisable under any applicable securities laws regarding public disclosure of business information. Landlord acknowledges that Tenant will include this Lease in filings with governmental agencies,
including without limitation the Securities and Exchange Commission, but only to the extent that such inclusion and/or disclosure is required under applicable securities laws. The foregoing notwithstanding, Landlord reserves the right to post a
press release or press releases, that discloses the fact that Landlord and Tenant have entered into a lease; provided that same does not disclose the location, economics or square footage related hereto. Any references in such press release or press
releases, in excess of the fact that Landlord and Tenant have entered into a lease, require approval by Tenant, which Tenant may withhold in its sole and absolute discretion. 

17.20 Incorporation of Schedules and Exhibits. All of the terms and conditions of all of the Schedules and Exhibits to this Lease are
hereby incorporated into this Lease. 
 17.21 Financial Statements. Within ten (10) business days after Landlord’s written
request therefor, which request shall be made only in the event that any actual or prospective lender, mortgagee or purchaser of the Building has required same, Tenant shall deliver Tenant’s Financial Statements to Landlord for the two

complete and correct in all material respects. Tenant’s failure to timely comply with this Section 17.21 shall be an Event of Default by Tenant under Section 15.1.4 of this Lease. Landlord hereby agrees to maintain Tenant’s
Financial Statements as proprietary and confidential and agrees not to disclose Tenant’s Financial Statements to any third party other than any actual or prospective lender, mortgagee, or purchaser of the Building, and Landlord’s
attorneys, accountants and similar business advisors. Notwithstanding the foregoing, this Section 17.21 shall not apply with regard to Tenant’s Financial Statements if, as the case may be, (a) the entity named as “Tenant” or

Landlord.

Third Party Tenant for the operation and control of all or part of the Premises, and in such event, the Lease will automatically, without consent or further action of Tenant, be deemed a sublease between the Third Party Tenant, as sub-landlord, and
Tenant, as subtenant. This provision is self-operating; however, Tenant agrees to execute any documents needed to confirm such sublease, Landlord will use commercially reasonable efforts cause the lessor under such Master Lease to execute a
reasonable non-disturbance and recognition agreement with Tenant simultaneously with the execution of such Master Lease, and if the Master Lease is entered into and Third Party Tenant defaults thereunder, Tenant will attorn to Landlord, as
substitute sublandlord, and, provided Tenant is not in default under the Lease after the expiration of any applicable notice and cure periods, Tenant may remain in possession of the Tenant Space under the terms of the Lease, even if Landlord should
terminate the Master Lease.

CALIFORNIA STATE LAW PROVISIONS 
  

	1.	REMEDIES FOR EVENTS OF DEFAULT. 

 1.1. Landlord’s Right to Terminate Upon Tenant
Default. In the event of any Event of Default by Tenant as provided in Section 15.1 of the Lease, Landlord shall have the right to terminate this Lease and recover possession of the Tenant Space by giving written notice to Tenant of
Landlord’s election to terminate this Lease, in which event Landlord shall be entitled to receive from Tenant: (a) the worth at the time of award of any unpaid Rent which had been earned at the time of such termination; plus (b) the
worth at the time of award of the amount by which the unpaid Rent which would have been earned after termination until the time of award exceeds the amount of such rental loss Tenant proves could have been reasonably avoided; plus (c) the worth
at the time of award of the amount by which the unpaid Rent for the balance of the Term after the time of award exceeds the amount of such rental loss that Tenant proves could be reasonably avoided; plus (d) any other amount necessary to
compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result therefrom; and (e) at Landlord’s
election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by Applicable Laws. As used in clauses (a) and (b), above, “worth at the time of award” shall be computed by allowing
interest at the then highest lawful contract rate of interest. As used in clause (c), above, “worth at the time of award” shall be computed by discounting such amount at the Discounting Rate (defined below). As used herein, the term
“Discounting Rate” means the lesser of (i) the Prime Rate plus one percent (1%), or (ii) the maximum rate permitted by Applicable Laws. 

1.2. Landlord’s Right To Continue Lease Upon Tenant Default. In the event of a default of this Lease and abandonment of the Tenant
Space by Tenant, if Landlord does not elect to terminate this Lease as provided in Section 1.1, above, Landlord may from time to time, without terminating this Lease, enforce all of its rights and remedies under this Lease. Without limiting the
foregoing, Landlord shall have the remedy described in California Civil Code Section 1951.4 (Landlord may continue this Lease in effect after Tenant’s breach and abandonment and recover Rent as it becomes due, if Tenant has the right to
sublet or assign, subject only to reasonable limitations). To the fullest extent permitted by Applicable Law, the proceeds of any reletting shall be applied first to pay to Landlord all costs and expenses of such reletting (including without
limitation, costs and expenses of retaking or repossessing the Tenant Space, removing persons and property therefrom, securing new tenants, including expenses for refixturizing, alterations and other costs in connection with preparing the Tenant
Space for the new tenant, and if Landlord shall maintain and operate the Tenant Space, the costs thereof) and receivers’ fees incurred in connection with the appointment of and performance by a receiver to protect the Tenant Space and
Landlord’s interest under this Lease and any necessary or reasonable alterations; second, to the payment of any indebtedness of Tenant to Landlord other than Rent due and unpaid hereunder; third, to the payment of Rent due and unpaid hereunder;
and the residue, if any, shall be held by Landlord and applied in payment of other or future obligations of Tenant to Landlord as the same may become due and payable, and Tenant shall not be entitled to receive any portion of such revenue. No
re-entry or taking of possession of the Tenant Space by Landlord pursuant to this Section 1.2 shall be construed as an election to terminate this Lease unless a written notice of such election shall be given to Tenant or unless the termination
thereof be decreed by a court of competent jurisdiction. Notwithstanding any reletting without termination by Landlord, Landlord may, at any time after such reletting, elect to terminate this Lease for any such Event of Default. Upon the occurrence
of an Event of Default by Tenant under Section 15.1 of the Lease, if the Tenant Space or any portion thereof are sublet, Landlord, in addition and without prejudice to any other remedies herein provided or provided by Applicable Laws, may, at
its option, collect directly from the sublessee all rentals becoming due to the Tenant and apply such rentals against other sums due hereunder to Landlord. 

1.3. Efforts to Relet. For the purposes of this Exhibit “D”, Tenant’s right to possession shall not be deemed to
have been terminated by efforts of Landlord to relet the Tenant Space (or any portion 

  
 -1- 

 
thereof), by its acts of maintenance or preservation with respect to the Tenant Space (or any portion thereof), or by appointment of a receiver to protect Landlord’s interests hereunder. The
foregoing enumeration is not exhaustive, but merely illustrative of acts which may be performed by Landlord without terminating Tenant’s right to possession. 

1.4. Waiver of Right of Redemption. Tenant hereby waives for Tenant and for all those claiming under Tenant all right now or hereafter
existing to redeem by order or judgment of any court or by any legal process or writ, Tenant’s right of occupancy of the Tenant Space after any termination of this Lease. Notwithstanding any provision of this Lease to the contrary, the
expiration or termination of this Lease and/or the termination of Tenant’s rights to possession of the Tenant Space shall not discharge, relieve or release Tenant from any obligation or liability whatsoever under any indemnity provision of this
Lease, including without limitation the provisions of Section 14.2 of this Lease. 
 1.5. Cumulative Remedies; Equitable Relief.
The specific remedies to which Landlord may resort under the provisions of this Lease are cumulative and are not intended to be exclusive of any other remedies or means of redress to which it may be lawfully entitled in case of any breach or
threatened breach by Tenant of any provisions of this Lease. In addition to the other remedies provided in this Lease, subject to Applicable Laws, Landlord shall be entitled to a restraint by injunction of the violation or attempted or threatened
violation of any of the covenants, conditions or provisions of this Lease or to a decree compelling specific performance of any such covenants, conditions or provisions. 

1.6. Tenant’s Waiver. Tenant acknowledges that Landlord has entered into this Lease in reliance upon, among other matters,
Tenant’s agreement and continuing obligation to pay all Rent due throughout the Term. As a result, if Landlord elects, at Landlord’s sole option, to attempt to relet all or any part of the Tenant Space, Tenant agrees that Landlord has no
obligation to: (i) relet the Tenant Space prior to leasing any other space within the Datacenter or Building; (ii) relet the Tenant Space (a) at a rental rate or otherwise on terms below market, as then determined by Landlord in its
sole discretion; (b) to any entity not satisfying Landlord’s then standard financial credit risk criteria or Datacenter criteria regarding security/interconnectivity; (c) for a use or upon terms not substantially consistent with the
terms and requirements of this Lease; (iii) make any alterations to the Tenant Space, the Datacenter or the Building; and/or (iv) otherwise incur any costs in connection with any such reletting, unless Tenant unconditionally delivers to
Landlord, in good and sufficient funds, the full amount thereof in advance. 
 1.7. Landlord’s Right to Cure. All covenants and
agreements to be performed by Tenant under this Lease shall be performed by Tenant at Tenant’s sole cost and expense. If Tenant should fail to make any payment (other than Base Rent) or cure any default hereunder within the time herein

 FIRST AMENDMENT 

TO 
 TURN KEY
DATACENTER LEASE 
 THIS FIRST AMENDMENT TO TURN KEY DATACENTER LEASE (this “Amendment”) is made and
entered into as of the latest date of execution as set forth on the signature page hereof (the “1A Effective Date”), by and between DIGITAL ALFRED, LLC, a Delaware limited liability company
(“Landlord”), and CONSTANT CONTACT, INC., a Delaware corporation (“Tenant”). 
 W I
T N E S S E T H: 
 WHEREAS, Landlord and Tenant have heretofore entered into that certain Turn Key Datacenter Lease having an
effective date of December 31, 2010 (the “TKD Lease”), covering approximately 3,600 total square feet of area (the “Premises”) located in Suite 140 (the “Datacenter”), in
that certain building located at 3105 Alfred Street, Santa Clara, California (the “Building”); 
 WHEREAS,
Landlord and Tenant have heretofore entered into that certain POP Room Rider having an effective date of December 31, 2010 (the “POP Rider”), which amends and modifies the TKD Lease and covers (i) two
(2) one-quarter (1/4) racks in Suite 155 of the Building, and (ii) two (2) one-quarter (1/4) racks in Suite 142 of the Building (the TKD Lease and the POP Rider are referred to herein, collectively, as the
“Lease”); 
 WHEREAS, any capitalized term or phrase used in this Amendment shall have the same meaning as
the meaning ascribed to such term or phrase in the Lease unless expressly otherwise defined in this Amendment; and 
 WHEREAS,
Landlord and Tenant desire to further modify the terms of the Lease in accordance with the terms and conditions herein provided. 
 NOW,
THEREFORE, for and in consideration of the sum of Ten and No/100 Dollars ($10.00) and other good and valuable consideration paid by each party hereto to the other, the receipt and sufficiency of which are hereby mutually acknowledged, Landlord
and Tenant hereby agree as follows: 
 1. Early Access. 

A. Definitions. As used herein: 

(i) “Early Access” shall mean and refer to Tenant’s ability to enter Premises-A prior to the Commencement Date and
Premises-B prior to the Phase II Expansion Date, for the purposes of inspecting same and for performing Tenant Work. 

  
 -1- 

 (ii) “Early Access Date” shall mean and refer to the date upon which Landlord
provides Tenant the Early Access Notice. Landlord agrees to use commercially reasonable efforts to cause the Early Access Date to occur on or before April 1, 2011. 

(iii) “Early Access Notice” shall mean and refer to the notice from Landlord to Tenant notifying Tenant that Landlord has
advanced the Commencement Date Conditions sufficiently to allow Tenant to engage in certain activities of Tenant Work prior to the Commencement Date. 

(iv) “Early Access Period” shall mean and refer to (a) the period between the Early Access Date and the Commencement
Date, as it relates to Premises-A, and (b) the period between the Early Access Date and the Phase II Expansion Date, as it relates to Premises-B. 

(v) “Tenant Work” shall mean and refer to all installations in the Premises, other than the completion of the Commencement
Date Conditions, including the installation of Tenant’s Personal Property. 
 B. License. Landlord agrees to permit Tenant and
the other Tenant Parties to have Early Access in the Premises, on and after the Early Access Date, except during the performance of Commissioning of the Datacenter. Any such permission shall constitute a license only, conditioned upon Tenant and
Tenant’s contractors’ obtaining Landlord’s prior written consent (not to be unreasonably withheld) with regard to each item of Tenant Work that any of such parties desire to undertake during the Early Access Period. Notwithstanding
anything in the Lease or this Amendment to the contrary, the Early Access Period may be reduced by Landlord to the extent such Early Access materially interferes with Landlord’s ability to complete the Commencement Date Conditions on or before
the Target Commencement Date. Tenant’s Early Access shall be subject to (and, during such period, Tenant must comply with) all of the terms and provisions of this Lease, excepting only the payment of Base Rent; provided, however, Tenant’s
Early Access to Premises-B during Phase I shall not affect Tenant’s obligation to pay Base Rent during the Phase I period. Additionally, Tenant agrees that (a) Landlord’s obligations to provide services to Premises-A and/or the
equipment serving Premises-A shall commence on the Commencement Date and shall not apply during the Early Access Period for Premises-A, (b) Landlord’s obligations to provide services to Premises-B and/or equipment serving Premises-B shall
commence on the Phase II Expansion Date and shall not apply during the Early Access Period for Premises-B, and (c) Tenant shall be required to pay any and all electricity charges that accrue to the Premises during the Early Access Period. For
the avoidance of doubt, Tenant agrees that Tenant will only perform Tenant Work in the Premises during the Early Access Period, and that Tenant will not commence business operations in Premises-A prior to the Commencement Date, nor will Tenant
commence business operations in Premises-B prior to the Phase II Expansion Date. 
 2. Confidentiality. Each party agrees that
(i) the terms and provisions of this Amendment are confidential and constitute proprietary information of the parties; and (ii) as such, the terms and provisions of this Amendment are, and shall be, subject to the terms of
Section 17.19 of the Standard Lease Provisions of the TKD Lease.

 SECOND AMENDMENT 

TO 
 TURN KEY
DATACENTER LEASE 
 THIS SECOND AMENDMENT TO TURN KEY DATACENTER LEASE (this “Amendment”) is made and
entered into as of (but not necessarily on) the latest of the parties’ respective dates of execution set forth on the signature page hereof (the “2A Effective Date”), by and between DIGITAL ALFRED, LLC, a Delaware
limited liability company (“Landlord”), and CONSTANT CONTACT, INC., a Delaware corporation (“Tenant”). 

W I T N E S S E T H: 

WHEREAS, Landlord and Tenant have heretofore entered into that certain Turn Key Datacenter Lease having an effective date of
December 31, 2010 (the “Original TKD Lease”), as amended by that certain First Amendment to Turn Key Datacenter Lease having an effective date of March 31, 2011 (the “1A”; together with the
Original TKD Lease, collectively, the “TKD Lease”), covering approximately 3,600 total square feet of area located in Suite 140 and certain pathway rights (collectively, the “Tenant Space”), in that
certain building located at 3105 Alfred Street, Santa Clara, California (the “Building”); 
 WHEREAS,
Landlord and Tenant have heretofore entered into that certain POP Room Rider having an effective date of December 31, 2010 (the “POP Rider”), which amends and modifies the TKD Lease and covers (i) two (2) one-quarter (1/4) racks in Suite 155 of the Building, and (ii) two (2) one-quarter (1/4) racks in Suite 142 of the Building (the TKD Lease and the
POP Rider are referred to herein, collectively, as the “Lease”); 
 WHEREAS, the Lease commenced eighteen
(18) days following the Outside Completion Date set forth in the TKD Lease (the “Late Lease Commencement”); 

WHEREAS, each capitalized term or phrase used in this Amendment shall have the same meaning as the meaning ascribed to such term or
phrase in the Lease unless expressly otherwise defined in this Amendment; and 
 WHEREAS, Landlord and Tenant desire to further
modify the terms of the Lease in accordance with the terms and conditions herein provided. 
 NOW, THEREFORE, for and in
consideration of the sum of Ten and No/100 Dollars ($10.00) and other good and valuable consideration paid by each party hereto to the other, the receipt and sufficiency of which are hereby mutually acknowledged, Landlord and Tenant hereby agree as
follows: 
 1. Tenant Improvement Allowance; Installation Fee. 

A. 2A Tenant Improvement Allowance. Contemporaneously with Landlord’s execution of this Amendment, Landlord hereby agrees to
deliver the sum of 

  
 -1- 

 
$50,000.00 (the “2A Tenant Improvement Allowance”) to Tenant, as a tenant improvement allowance. Notwithstanding anything in the Lease to the contrary,
Tenant hereby (i) agrees that the 2A Tenant Improvement Allowance shall be Tenant’s sole and exclusive remedy with respect to the Late Lease Commencement, and (ii) releases and holds harmless Landlord and the other members of the
Landlord Group from any and all Claims arising from, in connection with, or in any manner related to the Late Lease Commencement (“Tenant’s Release”). Tenant’s Release shall survive the expiration or termination of
the Lease. 
 B. Installation Fee. Landlord and Tenant acknowledge that Landlord has not yet invoiced Tenant for, and Tenant
has not yet paid, the Installation Fee. Effective as of, and from and after, the 2A Effective Date, Landlord does hereby waive the Installation Fee contained in Item 9 of the Basic Lease Information of the TKD Lease. Accordingly, effective as
of, and from and after, the 2A Effective Date: 
 (i) Tenant shall no longer be obligated to pay the Installation Fee; 

(ii) Item 9 of the Basic Lease Information of the TKD Lease is hereby amended and restated in its entirety to read as follows: 

 

			
	9.    Intentionally Deleted:	  	Intentionally Deleted.

 (iii) Section 3.2 of the Standard Lease Provisions of the TKD Lease is hereby amended and restated in
its entirety to read as follows: 
 3.2 Installation Fee. Intentionally Deleted. 

2. Estoppel. Tenant hereby (a) confirms, to the best of Tenant’s actual knowledge, Landlord is not in default under the
Lease as of the date this Amendment is executed by Tenant, and (b) confirms that, to the best of Tenant’s actual knowledge, as of the date this Amendment is executed by Tenant, Landlord has no outstanding obligations with respect to the
Tenant Space and/or under the Lease that would, with the passage of time, the giving of notice, or both, result in Landlord being in default under the Lease. 

3. Confidentiality. Each party agrees that the terms and provisions of this Amendment are confidential and shall be governed by
Section 17.19 of the Standard Lease Provisions of the TKD Lease as though the terms hereof were originally part of the Lease. 
 4.
Miscellaneous. 
 A. In the event that the terms of the Lease conflict or are inconsistent with those of this Amendment, the
terms of this Amendment shall govern. In that connection, the Lease is hereby amended as and where necessary, even though not specifically referred to herein, in order to give effect to the terms of this Amendment. 

B. Except as amended by this Amendment, the terms of the Lease are ratified by the parties and remain in full force and effect.

 C. Submission of this Amendment for examination does not constitute an offer, right of first
refusal, reservation of, or option for, any premises in or on the Building. This Amendment shall become effective only upon execution and delivery by both Landlord and Tenant. 

D. This Amendment may be executed simultaneously in two or more counterparts each of which shall be deemed an original, but all of which shall
constitute one and the same Amendment. Landlord and Tenant agree that the delivery of an executed copy of this Amendment by facsimile or e-mail shall be legal and binding and shall have the same full force and
effect as if an original executed copy of this Amendment had been delivered.
