“ARTICLE 58.” 

TENANT’S RIGHT OF FIRST OFFER 

58.1 As used herein, “Offer Space” means Suite 200 in the 3200 Bridge Building. Landlord may from time to time give Tenant a written
notice (the “Availability Notice”) identifying the particular Offer Space (the “Specific Offer Space”) that is Available (as defined below). As used herein, “Available” means that the space (i) is not part of the
Premises, (ii) is not then subject to a lease, (iii) is not then subject to any rights of tenant to renew their lease or expand their premises as set forth in their lease, and (iv) is not then subject to any negotiations between
Landlord and a prospective tenant or an existing tenant. 

  
 -2- 

 58.2 Tenant may inform Landlord (the “Request Notice”) not more than once in any twelve
(12) month period and not within six (6) months after receipt of an Availability Notice that Tenant desires to lease additional space. Landlord shall, within ten (10) business days of receiving the properly given Request Notice,
deliver to Tenant an Availability Notice identifying Specific Offer Space that is Available. 
 58.3 The location and configuration of the
Specific Offer Space shall be determined by Landlord in its reasonable discretion; provided that Landlord shall have no obligations to designate Specific Offer Space that would result in any space not included in the Specific Offer Space being not
Configured For Leasing (as defined below). For purposes of this Lease, “Configured For Leasing” means the applicable space must have convenient access to the central corridor on the applicable floor and must have a size and configuration
that complies with all applicable building codes and other laws and is such that Landlord judges, in its reasonable discretion, that Landlord will be able to lease such space to a third party. The Availability Notice shall: 

(a) Describe the particular Specific Offer Space (including rentable area, usable area and location); 

(b) Include an attached floor plan identifying such space; 

(c) State the date (the “Specific Offer Space Delivery Date”) the space will be available for delivery to Tenant;

 (d) Specify the Base Rent for the Specific Offer Space; 

(e) Specify the increase in the security deposit that will apply to reflect the addition of the Specific Offer Space to the
Premises; and 
 (f) If the Specific Offer Space Delivery Date is after the third (3rd) anniversary of the Suite 201
Third Expansion Space Commencement Date, specify the length of the term of the leasing of the Specific Offer Space that will be available (the “Specific Offer Space Term”). 

58.4 If Tenant wishes to exercise Tenant’s rights set forth in this Article 58 with respect to the Specific Offer Space, then within
five (5) business days of delivery of the Availability Notice to Tenant, Tenant shall deliver irrevocable notice to Landlord (the “First Offer Exercise Notice”) offering to lease the Specific Offer Space on the terms and conditions as
may be specified by Landlord in the Availability Notice. 
 58.5 In the event Tenant fails to give a First Offer Exercise Notice in response
to any Availability Notice, Tenant shall have no further rights to receive an Availability Notice and Tenant’s rights under this Article 58 shall terminate and Landlord shall be free to lease the Offer Space to anyone on any terms at any
time during the Term, without any obligation to provide Tenant with any further right to lease that space. 

  
 -3- 

 58.6 If Tenant timely and validly gives the First Offer Exercise Notice, then beginning on the
Specific Offer Space Delivery Date and continuing (i) if the Specific Offer Space Delivery Date is on or before the third (3rd) anniversary of the Suite 201 Third Expansion Space
Commencement Date, for the balance of the Term (including any extensions), or (ii) if the Specific Offer Space Delivery Date is after the third (3rd) anniversary of the Suite 201 Third
Expansion Space Commencement Date, for the Specific Offer Space Term: 
 (a) The Specific Offer Space shall be part of the
Premises under this Lease (so that the term “Premises” in this Lease shall refer to the space in the Premises immediately before the Specific Offer Space Delivery Date plus the Specific Offer Space). 

(b) Tenant’s Building Percentage with respect to the 3200 Bridge Building shall be adjusted to reflect the increased
rentable area of the Premises. 
 (c) Base Rent for the Specific Offer Space shall be as specified in the Availability
Notice. 
 (d) The security deposit Tenant must provide shall be increased by the amounts specified in the Availability
Notice. 
 (e) Tenant’s lease of the Specific Offer Space shall be on the same terms and conditions as affect the
original Premises from time to time, except as otherwise provided in this section. Tenant’s obligation to pay Rent with respect to the Specific Offer Space shall begin on the Specific Offer Space Delivery Date. The Specific Offer Space shall be
leased to Tenant in its “as-is” condition and Landlord shall not be required to construct improvements in, or contribute any tenant improvement allowance for, the Specific Offer Space. Tenant’s construction of any improvements in the
Specific Offer Space shall comply with the terms of this Lease concerning alterations. 
 58.7 Tenant’s rights and Landlord’s
obligations under this Article 58 are expressly subject to and conditioned upon there not existing an Event of Default by Tenant under this Lease, either at the time of delivery of the First Offer Exercise Notice or at the time the Specific
Offer Space is to be added to the Premises. 
 58.8 It is understood and agreed that Tenant’s rights under this Article 58 are
personal to Tenant and not transferable. In the event of any assignment or subletting of the Premises or any part thereof, this expansion right shall automatically terminate and shall thereafter be null and void. 

58.9 Tenant’s right of first offer under this Article 58 shall be subordinate to all rights of tenants under leases (or subleases) of the
Offer Space existing as of the Suite 201 

  
 -4- 

 
Third Expansion Space Commencement Date, and all rights of other tenants of the Project, which rights relate to the Offer Space and which rights are set forth in leases or subleases of space in
the Project existing as of the Suite 201 Third Expansion Space Commencement Date, each including any renewal, extension, expansion, first offer, first negotiation and other similar rights (regardless of whether such rights are executed strictly in
accordance with their respective terms or pursuant to lease amendments or new leases) (all such tenants under existing leases of the Offer Space and other tenants of the Project, collectively, the “Superior Right Holders”).” 

2.8 Landlord agrees that in consideration of Tenant entering into this Agreement, monthly Base Rent for the Suite 201 Third Expansion Space in
the amount of $27,431.25 shall be abated for the period from November 1, 2015 through December 31, 2015. The amount of Base Rent set forth in the table in Section 2.3 for that period reflects that rent abatement. During such abatement
period, Tenant shall still be responsible for the payment of all of its other monetary obligations under the Lease. In the event of an Event of Default by Tenant under the terms of the Lease that results in early termination pursuant to the
provisions of Article 22 of the Lease, then as part of the recovery set forth in Article 22 of the Lease, Landlord shall be entitled to the recovery of the monthly Base Rent that was abated under the foregoing provisions. 

3. Commencing on the date that is fourteen (14) days prior to the Suite 201 Third Expansion Space Commencement Date, Tenant shall be
entitled to have early access to the Suite 201 Third Expansion Space without the obligation for payment of rent and operating expenses for the purposes of installing its furniture, fixtures, cabling, files and equipment; and provided that
(a) Tenant first provides Landlord with all insurance required by the terms of the Lease, modified to apply to the Suite 201 Third Expansion Space, (b) all construction by Tenant shall be performed in accordance with the terms of the
Lease, including without limitation Article 15 and Exhibit L, and (c) Tenant has coordinated its schedule of early entry with Landlord to Landlord’s reasonable satisfaction. 

4. The taking of possession of the Suite 201 Third Expansion Space by Tenant shall be conclusive evidence that the Suite 201 Third Expansion
Space and the 3200 Bridge Building were in good and satisfactory condition at the time possession was taken by Tenant. Except as otherwise expressly stated above, neither Landlord nor Landlord’s agents have made any representations or
promises with respect to the condition of the 3200 Bridge Building, the Suite 201 Third Expansion Space, the land upon which the 3200 Bridge Building is constructed, or any other matter or thing affecting or related to the 3200 Bridge
Building or the Suite 201 Third Expansion Space, except as herein expressly set forth, and no rights, easements or licenses are acquired by Tenant by implication or otherwise except as expressly set forth in this Lease. 

5. Notwithstanding Section 4 above, Landlord warrants that the roof, structural components of the 3200 Bridge Building, the HVAC
system, electrical and plumbing systems, elevator, doors, parking lot and site lighting (the “Third Expansion Space Covered Items”), other than those constructed by Tenant, shall be in good operating condition on the date possession of the
Suite 201 Third Expansion Space is delivered to Tenant. If a non-compliance with such warranty exists as of the delivery of possession, or if one of such Third 

  
 -5- 

 
Expansion Space Covered Items should malfunction or fail within ninety (90) days after the delivery of possession to Tenant, Landlord shall, as Landlord’s sole obligation with respect
to such matter, promptly after receipt of written notice from Tenant setting forth in reasonable detail the nature and extent of such non-compliance, malfunction or failure, rectify the same at Landlord’s expense. If Tenant does not give
Landlord the required notice within ninety (90) days after the delivery of possession of the Suite 201 Third Expansion Space to Tenant, Landlord shall have no obligation with respect to that warranty other than obligations regarding the Third
Expansion Space Covered Items set forth elsewhere in this Lease. 
 6. Effective on the date of this Agreement, the amount of the Security
Deposit required under the Lease shall be increased by $31,800.34 and Tenant shall deposit said amount with Landlord on the date Tenant executes and delivers this Agreement. 

7. The following terms of the Fourth Amendment are hereby amended as follows: 

7.1 Section 4.5 of the Fourth Amendment is deleted in its entirety and replaced with the following: “The Maximum Parking Allocation
is increased by 28.” 
 7.2 The last two sentences of Section 12 of the Fourth Amendment are deleted in their entirety and
replaced with the following: 
 “Effective on the Suite 100 Second Expansion Space Commencement Date, the amount of the Security Deposit
required under the Lease shall be increased by $41,935.96 and Tenant shall deposit said amount with Landlord no later than the Suite 100 Second Expansion Space Commencement Date.” 

8. Except as otherwise provided herein, all of the terms and conditions of the Original Lease shall continue to apply during the Term;
provided, however, that there shall be no rent credit, and that there shall be no improvement allowance, Landlord construction obligations or other initial concessions with respect to the Term, except as provided in this Agreement and the Suite 201
Tenant Work Letter attached to this Agreement as Exhibit L. 
 9. Landlord hereby represents and warrants to Tenant that it has dealt
with no broker, finder or similar person in connection with this Agreement, and Tenant hereby represents and warrants to Landlord that it has dealt with no broker, finder or similar person in connection with this Agreement, other than
Cushman & Wakefield (“Landlord’s Broker”) and CBRE, Inc. (“Tenant’s Broker”). Landlord and Tenant shall each defend, indemnify and hold the other harmless with respect to all claims, causes of action,
liabilities, losses, costs and expenses (including without limitation attorneys’ fees) with respect to any leasing commission or equivalent compensation alleged to be owing on account of the indemnifying party’s dealings with any real
estate broker, agent, finder or similar person other than Landlord’s Broker and Tenant’s Broker. The commission with respect to this Agreement shall be paid to Landlord’s Broker by Landlord pursuant to a separate agreement.
Landlord’s Broker will pay Tenant’s Broker a commission pursuant to a separate agreement. Nothing in this Agreement shall impose any obligation on Landlord to pay a commission or fee to any party other than Landlord’s Broker. 

10. Time is of the essence of this Agreement and the provisions contained herein. 

  
 -6- 

 11. As additional consideration for this Agreement, Tenant hereby certifies that: 

(a) The Original Lease of the Existing Space is in full force and effect. 

(b) Tenant is in possession of the Premises denoted “Existing Space.” 

(c) To Tenant’s knowledge, there are not any uncured defaults on the part of Landlord or Tenant under the Original Lease.

 (d) All required contributions by Landlord to Tenant on account of Tenant’s improvements of the Existing Space have
been received. 
 (e) To Tenant’s knowledge, there are no existing defenses or offsets which Tenant or Landlord has
against the enforcement of the Original Lease by Landlord or Tenant. 
 (f) Tenant has not sublet any portion of the Premises
denoted “Existing Space” or assigned its interest in the Original Lease. 
 (g) Tenant’s representations and
warranties in Section 53.1 of the Original Lease are true and correct. 
 12. Except as specifically provided herein, the terms and
conditions of the Original Lease as amended hereby are confirmed and continue in full force and effect. This Agreement shall be binding on the heirs, administrators, successors and assigns (as the case may be) of the parties hereto. This Agreement
and the attached exhibits, which are hereby incorporated into and made a part of this Agreement, set forth the entire agreement between the parties with respect to the matters set forth herein. There have been no additional oral or written
representations or agreements. Under no circumstances shall Tenant be entitled to any Rent abatement, improvement allowance, leasehold improvements, or other work to the Premises, or any similar economic incentives that may have been provided to
Tenant in connection with entering into the Original Lease, unless specifically set forth in this Agreement. Tenant agrees that neither Tenant nor its agents or any other parties acting on behalf of Tenant shall disclose any matters set forth in
this Agreement or disseminate or distribute any information concerning the terms, details or conditions hereof to any person, firm or entity without obtaining the express written consent of Landlord. In the case of any inconsistency between the
provisions of the Original Lease and this Agreement, the provisions of this Agreement shall govern and control. Submission of this Agreement by Landlord is not an offer to enter into this Agreement but rather is a solicitation for such an offer by
Tenant. Landlord shall not be bound by this Agreement until Landlord has executed and delivered the same to Tenant. 
 13. Effective as of
the date hereof, all references to the “Lease” shall refer to the Original Lease, as amended by this Agreement. 

  
 -7- 

 14. As an inducement to Landlord to enter into this Agreement, Tenant hereby represents and
warrants that: (i) Tenant is not named on any list issued by the Office of Foreign Assets Control of the United States Department of the Treasury pursuant to Executive Order 13224 or any similar list or any law, order, rule or
regulation or any Executive Order of the President of the United States as a terrorist, “Specially Designated National and Blocked Person” or other banned or blocked person (any such person, group, entity or nation being hereinafter
referred to as a “Prohibited Person”); (ii) Tenant is not acting directly or indirectly for or on behalf of any Prohibited Person; and (iii) Tenant has not conducted and will not conduct business and has not engaged and will not
engage in any transaction or dealing with any Prohibited Person, including without limitation any assignment of the Lease or any subletting of all or any portion of the Premises or the making or receiving of any contribution of funds, goods or
services to or for the benefit of a Prohibited Person. Tenant covenants and agrees (a) to comply with all requirements of law relating to money laundering, anti-terrorism, trade embargos and economic sanctions, now or hereafter in effect,
(b) to immediately notify Landlord in writing if any of the representations, warranties or covenants set forth in this Section are no longer true or have been breached or if Tenant has a reasonable basis to believe that they may no longer be
true or have been breached, (c) not to use funds from any Prohibited Person to make any payment due to Landlord under the Lease and (d) at the request of Landlord, to provide such information as may be requested by Landlord to determine
Tenant’s compliance with the terms hereof. Any breach by Tenant of the foregoing representations and warranties shall be deemed a default by Tenant under this Lease and shall be covered by the indemnity provisions of the Original Lease. The
representations and warranties contained in this Section shall be continuing in nature and shall survive the expiration or earlier termination of the Lease. 

15. It is understood that from time to time during the term of the Lease, Landlord may be subject to the provisions of the Employee Retirement
Income Security Act of 1974, as amended (“ERISA”) and as a result may be prohibited by law from engaging in certain transactions. Tenant represents and warrants to the best of its knowledge after due inquiry that at the time the Lease is
entered into and at any time thereafter when its terms are amended or modified, neither Tenant nor its affiliates (within the meaning of part VI(c) of Department of Labor Prohibited Transaction Class Exemption 84-14 (“PTE 84-14”, as
amended), has or will have the authority to appoint or terminate The Prudential Insurance Company of America (“Prudential”) as an investment manager to any employee benefit plan then holding a ten percent (10%) or greater interest in
the Prudential separate account PRISA II, nor the authority to negotiate the terms of any management agreement between Prudential and any such employee pension benefit plan for its investment in PRISA II. Further, Tenant is not “related”
to Prudential within the meaning of part VI(h) of PTE 84-14. 
 16. Pursuant to California Civil Code Section 1938, Tenant is hereby
notified that, as of the date hereof, neither the 3200 Bridge Building nor the 3400 Bridge Building has undergone an inspection by a “Certified Access Specialist” and Landlord makes no representations as to the compliance of the
Premises, the 3200 Bridge Building or the 3400 Bridge Building with accessibility standards. 
 17. If Tenant is billed directly
by a public utility with respect to Tenant’s electrical usage at the Premises, upon request from time to time, Tenant shall provide monthly electrical 

  
 -8- 

 
utility usage for the Premises to Landlord for the period of time requested by Landlord (in electronic or paper format) or, at Landlord’s option, provide any written authorization or other
documentation required for Landlord to request information regarding Tenant’s electricity usage with respect to the Premises directly from the applicable utility company.

 EXHIBIT L 

SUITE 201 TENANT WORK LETTER 

This Suite 201 Tenant Work Letter is attached to and made a part of that certain Fifth Amendment to Lease dated October 28, 2015 (the
“Amendment”) between WESTPORT OFFICE PARK, LLC, a California limited liability company (“Landlord”), and IMPERVA, INC., a Delaware corporation (“Tenant”), which amends a lease between Landlord and Tenant (as modified
from time to time, the “Lease”) more particularly described in the Amendment. Any capitalized term used and not otherwise defined in this Suite 201 Tenant Work Letter has the meaning given such term in the Amendment (or, if not defined in
the Amendment, the meaning given such term in the Lease). This Suite 201 Tenant Work Letter sets forth the terms and conditions relating to the construction of the Suite 201 Third Expansion Space Improvements in the Suite 201 Third Expansion Space.

 Section 1 
 BASE,
SHELL AND CORE 
 1.1 Base, Shell and Core. Landlord has previously constructed the base, shell, and core (i) of the Suite 201
Third Expansion Space and (ii) of the floor(s) of the Building on which the Suite 201 Third Expansion Space are located (collectively, the “Base, Shell, and Core”) and other improvements, and Tenant shall accept the Base, Shell and
Core and such other improvements in their current “As-Is” condition existing as of the date of the Amendment and the Suite 201 Third Expansion Space Commencement Date. Tenant shall install in the Suite 201 Third Expansion Space certain
“Suite 201 Third Expansion Space Improvements” (as defined below) pursuant to the provisions of this Suite 201 Tenant Work Letter. Except for Landlord’s obligation to disburse the Suite 201 Third Expansion Space Improvement Allowance
as described below, Landlord shall not be obligated to make or pay for any alterations or improvements to the Suite 201 Third Expansion Space, the Premises, the Building or the Project. 

1.2 Landlord Path of Travel Obligation. Notwithstanding anything to the contrary contained herein, Landlord covenants to correct any
failure of the path of travel for the Suite 201 Third Expansion Space outside of the Premises to comply with current codes, including without limitation the Americans with Disabilities Act, as interpreted by Landlord’s architect as of the date
of the Amendment, to the extent such correction is necessary in order for Tenant to obtain a building permit or a certificate of occupancy for the Suite 201 Third Expansion Space Improvements in the 201 Third Expansion Space for general office
purposes; provided that nothing contained herein shall be deemed to prohibit Landlord from obtaining a variance or relying upon a grandfathered right in order to achieve compliance with those codes. Notwithstanding the foregoing, Landlord shall have
the right to contest any alleged violation in good faith, including, without limitation, the right to apply for and obtain a waiver or deferment of compliance, the right to assert any and all defenses allowed by law, and the right to appeal any
decisions, judgments or rulings to the fullest extent permitted by law, and Landlord’s obligation to perform work or take such other action to cure a violation under this Section shall apply after the exhaustion of any and all rights to appeal
or contest. 

  
 Exhibit L

 Section 2 

SUITE 201 THIRD EXPANSION SPACE IMPROVEMENTS 

2.1 Suite 201 Third Expansion Space Improvement Allowance. Tenant shall be entitled to a one-time tenant improvement allowance (the
“Suite 201 Third Expansion Space Improvement Allowance”) in the amount of up to, but not exceeding $10.00 per rentable square foot of the Suite 201 Third Expansion Space (i.e., up to $73,150.00, based on 7,315 rentable square feet
in the Suite 201 Third Expansion Space), for the costs relating to the initial design and construction of Tenant’s improvements which are permanently affixed to the Suite 201 Third Expansion Space (the “Suite 201 Third Expansion Space
Improvements”); provided, however, that Landlord shall have no obligation to disburse all or any portion of the Suite 201 Third Expansion Space Improvement Allowance to Tenant unless Tenant makes a request for disbursement pursuant to the terms
and conditions of Section 2.2 below prior to that date which is twelve (12) months after the Suite 201 Third Expansion Space Commencement Date. In no event shall Landlord be obligated to make disbursements pursuant to this Suite 201
Tenant Work Letter in a total amount which exceeds the Suite 201 Third Expansion Space Improvement Allowance. Tenant shall not be entitled to receive any cash payment or credit against Rent or otherwise for any unused portion of the Suite 201 Third
Expansion Space Improvement Allowance which is not used to pay for the Suite 201 Third Expansion Space Improvement Allowance Items (as such term is defined below). In no event shall the Suite 201 Third Expansion Space Improvement Allowance be used
for purposes of constructing improvements in the Premises for purposes of offering space for sublease or for the benefit of a subtenant. Notwithstanding anything contained in this Agreement to the contrary, the Suite 201 Third Expansion Space
Improvement Allowance may, in Tenant’s unfettered and absolute discretion, be allocated partially to the Suite 201 Third Expansion Space Improvements or partially to the design and construction of Tenant’s improvements that are permanently
affixed to the Existing Space (the “Existing Space Improvements”). The intention of this provision is to provide complete discretion to Tenant to allocate the Suite 201 Third Expansion Space Improvement Allowance between the Suite 201
Third Expansion Space Improvements and the Existing Space Improvements. For purposes of approvals, disbursement of funds, removal, restoration and other process provisions, Existing Space Improvements shall be treated under this Agreement as though
they were Suite 201 Third Expansion Space Improvements. 
 2.2 Disbursement of the Suite 201 Third Expansion Space Improvement
Allowance. 
 2.2.1 Suite 201 Third Expansion Space Improvement Allowance Items. Except as otherwise set forth in this Suite 201

2.2.1.5 The cost of any changes to the Construction Drawings or Suite 201 Third Expansion Space Improvements required by applicable laws and
building codes (collectively, “Code”);

shall retain the engineering consultants designated by Landlord (the “Engineers”) to prepare all plans and engineering working drawings relating to the structural, mechanical, electrical, plumbing, HVAC, lifesafety, and sprinkler work in
the Suite 201 Third Expansion Space. The plans and drawings to be prepared by Architect and the Engineers hereunder shall be known collectively as the “Construction Drawings.” All Construction Drawings shall comply with the drawing format
and specifications reasonably determined by Landlord, and shall be subject to Landlord’s approval. Tenant and Architect shall verify, in the field, the dimensions and conditions as shown on the relevant portions of the base building plans, and
Tenant and Architect shall be solely responsible for the same, and Landlord shall have no responsibility in connection therewith. Landlord’s review of the Construction Drawings as set forth in this Section 3, shall be for its sole
purpose and shall not imply Landlord’s review of the same, or obligate Landlord to review the same, for quality, design, Code compliance or other like matters. Accordingly, notwithstanding that any Construction Drawings are reviewed by Landlord
or its space planner, architect, engineers and consultants, and notwithstanding any advice or assistance which may be rendered to Tenant by Landlord or Landlord’s space planner, architect, engineers, and consultants, Landlord shall have no
liability whatsoever in connection therewith and shall not be responsible for any omissions or errors contained in the Construction Drawings.

before any architectural working drawings or engineering drawings have been commenced. The final space plan (the “Final Space Plan”) shall include a layout and designation of all offices, rooms and other partitioning, their intended use,
and equipment to be contained therein. Landlord may request clarification or more specific drawings for special use items not included in the Final Space Plan. Landlord shall advise Tenant within five (5) business days after Landlord’s
receipt of the Final Space Plan for the Premises if the same is unsatisfactory or incomplete in any respect. If Tenant is so advised, Tenant shall promptly (i) cause the Final Space Plan to be revised to correct any deficiencies or other
matters Landlord may reasonably require, and (ii) deliver such revised Final Space Plan to Landlord.

Drawings to Landlord. 
 3.4 Approved Working Drawings. The Final Working Drawings shall be approved by Landlord (the “Approved
Working Drawings”) prior to the commencement of construction of the Premises by Tenant. After approval by Landlord of the Final Working Drawings, Tenant shall promptly submit the same to the appropriate governmental authorities for all
applicable building permits. Tenant hereby agrees that neither Landlord nor Landlord’s consultants shall be responsible for obtaining any building permit or certificate of occupancy for the Premises and that obtaining the same shall be
Tenant’s responsibility; provided, however, that Landlord shall cooperate with Tenant in executing permit applications and performing other ministerial acts reasonably necessary to enable Tenant to obtain any such permit or certificate of
occupancy. No changes, modifications or alterations in the Approved Working Drawings may be made without the prior written consent of Landlord, which consent shall not be unreasonably withheld.

Landlord, or in the process of being disbursed by Landlord, on or before the commencement of construction of the Suite 201 Third Expansion Space Improvements). The Over-Allowance Amount shall be disbursed by Landlord prior to the disbursement of any
of the then remaining portion of the Suite 201 Third Expansion Space Improvement Allowance, and such disbursement shall be pursuant to the same procedure as the Suite 201 Third Expansion Space Improvement Allowance. In the event that, after the
Final Costs have been delivered by Landlord to Tenant, the costs relating to the design and construction of the Suite 201 Third Expansion Space Improvements shall change, any additional costs necessary to such design and construction in excess of
the Final Costs shall, to the extent they exceed the remaining balance of the Suite 201 Third Expansion Space Improvement Allowance, be paid by Tenant to Landlord immediately as an addition to the Over-Allowance Amount and, in any event, prior to
the commencement of the construction of such changes, or, at Landlord’s option, Tenant shall make payments for such additional costs out of its own funds, but Tenant shall continue to provide Landlord with the documents described in
Sections 2.2.2.1(i), (ii), (iii) and (iv) above, for Landlord’s approval, prior to Tenant paying such costs.

4.2.2.2 Coordination Fee. Tenant shall pay a logistical coordination fee (the “Coordination Fee”) to Landlord in an amount
equal to the product of (i) one percent (1%), and (ii) the sum of the Suite 201 Third Expansion Space Improvement Allowance, the Over-Allowance Amount, as such amount may be increased hereunder, and any other amounts expended by Tenant in
connection with the design and construction of the Suite 201 Third Expansion Space Improvements, which Coordination Fee shall be for services relating to the coordination of the construction of the Suite 201 Third Expansion Space Improvements. 

4.2.2.3 Indemnity. Tenant’s indemnity of Landlord as set forth in the Lease shall also apply with respect to any and all costs,
losses, damages, injuries and liabilities related in any way to any act or omission of Tenant or Tenant’s Agents, or anyone directly or indirectly employed by any of them, or in connection with Tenant’s non-payment of any amount arising
out of the Suite 201 Third Expansion Space Improvements and/or Tenant’s disapproval of all or any portion of any request for payment. Such indemnity by Tenant, as set forth in the Lease, shall also apply with respect to any and all costs,
losses, damages, injuries and liabilities related in any way to Landlord’s performance of any ministerial acts reasonably necessary (i) to permit Tenant to complete the Suite 201 Third Expansion Space Improvements, and (ii) to enable
Tenant to obtain any building permit or certificate of occupancy for the Premises. 
 4.2.2.4 Insurance Requirements. 

4.2.2.4.1 General Coverages. All of Tenant’s Agents shall carry worker’s compensation insurance covering all of their
respective employees, and shall also carry public liability insurance, including property damage, all with limits, in form and with companies as are required to be carried by Tenant as set forth in the Lease. 

4.2.2.4.2 Special Coverages. Tenant shall carry “Builder’s All Risk” insurance in an amount approved by Landlord
covering the construction of the Suite 201 Third Expansion Space Improvements, and such other insurance as Landlord may require, it being understood and agreed that the Suite 201 Third Expansion Space Improvements shall be insured by Tenant pursuant

(30) days prior written notice of any cancellation. In the event that the Suite 201 Third Expansion Space Improvements are damaged by any cause during the course of the construction thereof, Tenant shall immediately repair the same at

Landlord’s Property Manager, Landlord’s Asset Manager, and all mortgagees and ground lessors of the Building. All insurance, except Workers’ Compensation, maintained by Tenant’s Agents shall preclude subrogation claims by the
insurer against anyone insured thereunder. Such insurance shall provide that it is primary insurance as respects the owner and that any other insurance maintained by owner is excess and noncontributing with the insurance required hereunder. The

provided however, that Landlord’s failure to inspect the Suite 201 Third Expansion Space Improvements shall in no event constitute a waiver of any of Landlord’s rights hereunder nor shall Landlord’s inspection of the Suite 201 Third
Expansion Space Improvements constitute Landlord’s approval of the same. Should Landlord disapprove any portion of the Suite 201 Third Expansion Space Improvements, Landlord shall notify Tenant in writing of such disapproval and shall specify
the items disapproved. Any defects or deviations in, and/or disapproval by Landlord of, the Suite 201 Third Expansion Space Improvements shall be rectified by Tenant at no expense to Landlord, provided however, that in the event Landlord determines
that a defect or deviation exists or disapproves of any matter in connection with any portion of the Suite 201 Third Expansion Space Improvements and such defect, deviation or matter might adversely affect the mechanical, electrical, plumbing,
heating, ventilating and air conditioning or life-safety systems of the Building, the structure or exterior appearance of the Building or any other tenant’s use of such other tenant’s leased premises, Landlord may, take such action as
Landlord deems necessary, at Tenant’s expense and without incurring any liability on Landlord’s part, to correct any such defect, deviation and/or matter, including, without limitation, causing the cessation of performance of the
construction of the Suite 201 Third Expansion Space Improvements until such time as the defect, deviation and/or matter is corrected to Landlord’s satisfaction.

Tenant’s sole cost and expense. At the conclusion of construction, (i) Tenant shall cause the Architect and Contractor (A) to update the Approved Working Drawings as necessary to reflect all changes made to the Approved Working
Drawings during the course of construction, (B) to certify to the best of their knowledge that the “record-set” of as-built drawings are true and correct, which certification shall survive the expiration or termination of the Lease,

 2. It is hereby acknowledged that the Suite 100 Second Expansion Space is currently subject to a
lease (the “Existing Lease”) by and between Landlord or Landlord’s predecessor-in-interest and the existing tenant under the Existing Lease (the “Existing Tenant”). The parties hereto understand and agree that effectiveness
