SUBLEASE AGREEMENT 
 (301
Brannan Street, Third, Fourth and Fifth Floors) 
 THIS SUBLEASE AGREEMENT
(“Sublease”) is entered into effective February    , 2014 (the “Effective Date”) by and between StumbleUpon, Inc. a Delaware corporation (“Sublessor”) and Okta, Inc., a
Delaware corporation (“Sublessee”), and is made with respect to the following facts and circumstances. 
 A. Kilroy Realty,
L.P., a Delaware limited partnership (“Landlord”) is the owner of that certain office building commonly known as 301 Brannan Street, San Francisco, California (the “Building”). As of the Sublease Commencement Date
(as defined in Section 3 below), Sublessor will be leasing directly from Landlord the 2nd, 3rd, 4th, 5th and 6th floors of the Building (collectively, the “Master Premises”)
pursuant to that certain “Office Lease” dated December 15, 2011 (the “Master Lease”). A true and correct copy of the Master Lease is attached hereto as Exhibit A. 

B. Sublessee is in possession of 37,815 rentable square feet located on the 3rd, 4th, and 5th floors of the Building (collectively, the “Subleased Premises”) pursuant to an existing sublease and an existing
sub-sublease, and certain amendments thereto, all of which existing agreements (the “Existing Agreements”) expire on June 30, 2014. 

C. Sublessor and Sublessee now desire to enter into a sublease for the Subleased Premises following the expiration of the Existing Agreements,
and Landlords desire to consent to such subletting, on the terms and conditions set forth herein. 
 NOW, THEREFORE, in
recognition of the foregoing premises, in exchange of the promises, covenants and conditions set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Sublessor and Sublessee agree
as follows. 
 1. Subject to receipt of Landlord Consent (as defined in Section 18 below), Sublessor hereby subleases to Sublessee, and
Sublessee hereby subleases from Sublessor, the Subleased Premises (excluding risers, plenums and utility closets which serve other portions of the Building) on the terms, conditions and covenants contained in this Sublease during the term of this
Sublease. In addition to the Subleased Premises, Sublessee shall have the option to use during the Term (as defined below) up to 60% of that number of parking stalls within the Building currently allocated to Sublessor under the Master Lease;
provided, however, that Sublessee shall be responsible for (i) compliance with all of the rules and regulations promulgated from time to time by the parking vendor regarding such parking stalls, and (ii) the direct payment to the parking
vendor of all rental charges associated with such stalls. Prior to terminating any usage rights with respect to such parking stalls, Sublessee shall give Sublessor not less than thirty (30) days advanced notice of such pending termination and
Sublessor shall have the right to take over, and assume all obligations associated with, the parking stalls which Sublessee intends to terminate. 

2. Sublessee shall accept possession of the Subleased Premises in its “AS-IS” condition on the first day of the Term (as defined in
Section 3 below). Sublessee shall not have 

  
 1 

 
any right to require additional or other improvements as a condition of this Sublease, and Sublessee shall not make any material alterations to any component of the Subleased Premises except in
compliance with the provisions of Article 8 of the Master Lease without Sublessor’s prior written consent (which shall not be unreasonably withheld, conditioned or delayed), and the consent of Landlord. Sublessee shall have the right to use the
existing data communications cabling and wiring installed by Sublessor serving the Subleased Premises. Sublessee shall also have the right to use the personal property/furniture owned by Sublessor and existing in the Subleased Premises as of the
Effective Date, all of which is listed on the attached Exhibit B. Sublessee shall return all of the listed personal property/furniture to Sublessor in place within the Subleased Premises on the Sublease Expiration Date (or upon any earlier
termination of this Sublease), in the condition received, normal wear and tear excepted. Sublessee shall comply with and abide by the provisions of the Master Lease in making all improvements and repairs, and performing all maintenance, to the
Subleased Premises. Sublessee shall also be responsible for all janitorial activities required at the Subleased Premises and covenants to keep the Subleased Premises, including the restrooms located within the Subleased Premises, in a good and clean
condition at all times. 
 3. The term of this Sublease (the “Term”), and Sublessee’s right to possession and
occupancy of the Subleased Premises hereunder, shall commence on July 1,2014 (subject to receipt of the Landlord Consent prior thereto) (“Sublease Commencement Date”) and shall terminate on June 30, 2017 (“Sublease
Expiration Date”), unless sooner terminated pursuant to any provision hereof or of the Master Lease. 
 4. A. Sublessee shall pay
monthly rent to Sublessor as follows: 
  

					
	 Period
	  	Monthly Rent	 
	 Months 1-12
	  	$	167,016.25	  
	 Months 13-24
	  	$	172,026.73	  
	 Months 25-36
	  	$	177,187.53	  

 Sublessee shall make all rent payments due hereunder on or before the first day of the month for which such rent is due. 

B. Sublessor shall cause electricity, water, garbage removal and natural gas to be provided to the Subleased Premises and Sublessee shall
additionally reimburse Sublessor on a monthly basis for Sublessee’s equitable share of the cost of such utilities, as reasonably determined by Sublessor and reasonably acceptable to Sublessee. During the Term Sublessee shall also be responsible
for Sublessee’s Share of the payment of any Direct Expenses and/or Additional Rent (as defined, and as calculated, pursuant to the Master Lease) payable by Sublessor under the Master Lease for the Master Premises. All such payments and
reimbursements required to be made by Sublessee hereunder shall be paid to Sublessor no later than thirty (30) days following receipt of an invoice therefor from Sublessor. All monthly rent and other payments shall be made without set-off,
deduction or reduction of any kind. In the event of overpayment of any charge by Sublessee, Sublessor shall promptly notify Sublessee 

  
 2 

 
thereof and, in any event, reimburse Sublessee for its amount of overpayment within thirty (30) days after receipt thereof by Sublessor. Sublessee’s Share shall be 60.17% of
“Tenant’s Share” of all Additional Rent payable by Sublessor under the Master Lease. Sublessee’s Share is determined by dividing the rentable square footage of the Subleased Premises (i.e., 37,815 rentable square feet) by the
rentable square footage of the Master Premises (i.e., 62,852 rentable square feet). 
 C. Pursuant to Section 4.6 of the Lease,
Sublessor has a right to review Landlord’s records of Building Direct Expenses for the subject Expense Year. Sublessor promptly shall provide Sublessee with a copy of any Statement received by Sublessor from Landlord. If, within thirty
(30) days after receipt of the Statement from Sublessor, Sublessee notifies Sublessor that Sublessee reasonably believes that Landlord’s records should be reviewed with respect to the items identified by Sublessee, and such items, in
Sublessor’s reasonable judgment, should be reviewed, Sublessor shall exercise the audit rights set forth in Section 4.6 in accordance therewith; provided, however, that all expenses and charges associated with such Sublessee-requested
audit shall be borne by Sublessee. 
 5. Sublessee shall, in lieu of a security deposit, deliver to Sublessor a letter of credit from
Silicon Valley Bank substantially in the form attached hereto as Exhibit B (or otherwise in a commercially reasonable form) in the amount of $688,106.92. Sublessee shall deliver the letter of credit to Sublessor not later than the Sublease
Commencement Date. Sublessor shall not be obligated to return the letter of credit until (and it shall not expire before) such time as Sublessor has confirmed after expiration of the Term that Sublessee has paid all rent, utility charges, Pass
Through Costs and Additional Rent and other expenses of the Subleased Premises which are Sublessee’s responsibility hereunder and has returned the Subleased Premises to Sublessor in good condition and repair, excepting only normal wear and
tear, casualty damage and repairs which are not the obligation of Sublessee under this Sublease but in no event later than thirty (30) days after the expiration date of this Sublease. Sublessor shall have the right to draw against the letter of
credit any amount reasonably required to cure any default, beyond applicable notice and cure periods, by Sublessee under this Sublease, including to restore the Subleased Premises to such required condition at the end of the Term in the event
Sublessee fails to do so. Sublessee shall pay all expenses, points and/or fees incurred by Sublessee in obtaining the letter of credit and any renewal, extension or replacement thereof. If, (i)(A) Sublessor receives notice from the issuing bank of
its intention not to renew the letter of credit and (B) Sublessee fails to deliver a replacement letter of credit at least five (5) business days prior to the expiration of the then existing letter of credit or (ii) Sublessee fails to
deliver a renewal or replacement letter of credit (it being agreed that any replacement letter of credit shall satisfy the requirements of this Section 5) at least five (5) business days prior to the expiration of the then existing letter
of credit, then Sublessor shall be entitled to draw the full face amount of the letter of credit and retain such amount as an additional security deposit hereunder in lieu of the letter of credit. If Sublessor draws upon any part of the letter of
credit and/or applies or retains any portion or all of the amount received from such draw, Sublessee, within three (3) business days after receipt of written demand, shall restore the face amount of the letter of credit or deposit with Landlord
cash equal to the amount so applied or retained. For the purposes of the definition of “default” under this Section 5, the terms of the Master Lease are hereby incorporated herein as applicable between Sublessor and Sublessee. The
letter of credit shall be reduced (through a replacement letter of credit) by $172,026.73 following the eighteenth (18 ) month of the Term, and by an 

  
 3 

 
additional $172,026.73 following the thirtieth (30th) month of the Term provided that Sublessee shall not have been in default of this
Sublease beyond any applicable cure period at any time prior to the date of any such reduction. Sublandlord shall cooperate with the issuing bank in canceling the letter of credit it is then holding within three (3) business days after receipt
of each replacement letter of credit in the reduced amount. 
 6. During the Term, Sublessee shall procure and maintain a policy of
liability insurance naming Sublessor and Landlord as additional insureds in the amount and scope required of Sublessor under the Master Lease. Sublessee shall provide Sublessor with a certificate of insurance evidencing such required coverage prior
to the Sublease Commencement Date. Sublessee shall also maintain the property insurance coverage and other coverages required under the Master Lease with respect to the Subleased Premises and provide Sublessor with a certificate of insurance with
respect to such coverages prior to the Sublease Commencement Date. Sublessor shall maintain all insurance required to be maintained by it as tenant under the Master Lease (except, at such time as Sublessor shall not occupy any portion of the
Building, Sublessor may reduce its liability coverage under the Master Lease to the extent Landlord agrees in writing that liability coverage maintained by Sublessee pursuant to this Section is an acceptable substitute for the liability coverage
required of Sublessor under the Master Lease) provided, as to property insurance pursuant to Section 10.3.2 of the Master Lease, unless Landlord contends that to do so would be a violation of the Master Lease, Sublessor shall be required only
to maintain coverage applicable to the portion of the Master Premises not a part of the Subleased Premises . In no event shall either party be responsible to the other party for any loss or damage to persons or property to the extent covered by
insurance required to be maintained under this Sublease or actually maintained by the party suffering such loss or damage. With respect to any waivers of subrogation contained in the Master Lease, as incorporated herein, such waivers shall be deemed
to be modified to constitute an agreement by and among Landlord, Sublessor and Sublessee (and Landlord’s consent to this Sublease, if given, shall be deemed to constitute its approval of this modification). 

7. Sublessee shall use the Subleased Premises only for the permitted uses set forth in the Master Lease and for no other purpose without
Sublessor’s prior written consent (which may be withheld in Sublessor’s sole discretion). Sublessee shall abide by all the provisions of the Master Lease concerning the storage, use and handling of hazardous materials at the Subleased
Premises. Sublessor shall defend, indemnify and hold Sublessee harmless from and against any and all claims, liabilities, responsibilities, costs and expenses (including reasonable attorneys’ fees and costs) made against or incurred by
Sublessee to the extent arising out of or relating to the storage, use and handling of hazardous materials stored, used, released or disposed of by Sublessor, its agents, employees or contractors on, in, under or about the Subleased Premises. The
foregoing indemnity shall survive the expiration or earlier termination of this Sublease. 
 8. Sublessee’s performance of each of its
obligations under this Sublease constitutes a covenant, and Sublessee’s right to continue in possession of the Subleased Premises is conditioned upon such performance, subject to all notice and cure rights and remedies of Sublessee and
Sublessor as set forth in the Master Lease incorporated herein. In addition, Sublessee shall be in default of its obligations under this Sublease if Sublessee is responsible for the occurrence of any of the “Events of Default” set forth in
Article 19 of the Master Lease. In the event of any default (after applicable notice and cure periods) by Sublessee of this Sublease, 

  
 4 

 
Sublessor shall have all remedies provided by applicable law, and shall additionally have the right to pursue all remedies set forth herein, including rights and remedies incorporated herein from
the Master Lease, including without limitation, termination and/or eviction as to the Subleased Premises. All of Sublessor’s remedies shall be cumulative, not exclusive. In the event of eviction, Sublessee shall be liable for all damages caused
thereby to the extent expressly set forth in Article 19 of the Master Lease. 
 9. Sublessee shall defend, indemnify and hold Sublessor
harmless from and against any and all claims, liabilities, responsibilities, costs (including reasonable attorneys’ fees and costs) and expenses made against or incurred by Sublessor to the extent arising from or relating to any of the
following: (a) Sublessee’s failure to perform any covenant, condition or provision to be performed by Sublessee pursuant to this Sublease or the Master Lease (to the extent incorporated into this Sublease); and/or (b) personal injury
or property damage suffered at the Subleased Premises on or after Sublessee’s occupancy thereof, except to the extent caused by the negligence or willful misconduct of Sublessor. Sublessor shall defend, indemnify and hold Sublessee harmless
from and against any and all claims, liabilities, responsibilities, costs and expenses (including reasonable attorneys’ fees and costs) made against or incurred by Sublessee to the extent arising out of or relating to any of the following:
(a) Sublessor’s failure to perform any covenant, condition or provision to be performed by Sublessor under this Sublease or the Master Lease (to the extent not made the obligation of Sublessee under this Sublease); and/or (b) personal
injury or property damage caused by the negligence or willful misconduct of Sublessor or any of its employees. The provisions of this Section shall survive expiration or earlier termination of the Master Lease or this Sublease. For purposes of this
Section, “Sublessee” and “Sublessor” shall include their respective officers, directors, agents, shareholders, employees, agents, contractors, subcontractors and permitted assignees and successors. 

10. Sublessee shall not assign or sublet the Subleased Premises or any portion thereof without first obtaining the written consent of
Sublessor, which shall not be unreasonably withheld, conditioned or delayed, and Landlord in accordance with the provisions of Article 14 of the Master Lease. All costs of assignment and/or sub-subleasing shall be borne by Sublessee in accordance
with the Master Lease. With respect to any “Permitted Transferee” as described in Section 14.8 of the Master Lease, the provisions of said section of the Master Lease shall apply as if incorporated into this Sublease provided, however
Sublessee shall give Sublessor not less than forty-five (45) days prior notice of any transfer involving a “Permitted Assignment” to allow Sublessor to confirm with Landlord that Landlord concurs the transfer constitutes a transfer to
a “Permitted Transferee” not requiring their consent, or alternatively to obtain their consent if they do not so concur. Sublessor acknowledges, however, that prior notice of a Permitted Assignment may be prohibited by applicable
securities laws, in which event Sublessee shall give Sublessor written notice as soon as possible after the effective date of the Permitted Assignment. Prior to taking any marketing or other steps toward assigning this Sublease or subletting any
portion of the Subleased Premises, Sublessee shall provide written notice to Sublessor and Sublessor shall have the right to terminate this Sublease as to such portion of the Subleased Premises and recapture possession of the subject portion of the
Subleased Premises by giving Sublessee written notice of such election not later than ten (10) business days following receipt of Sublessee’s written notice of intent to sublease/assign. If Sublessor does not give such notice in a timely
manner, Sublessee shall be free to market and assign or sublet, subject to the provisions of Article 14 of the Master Lease. 

  
 5 

 11. Any signage desired by Sublessee shall be at Sublessee’s expense and shall be subject to
the provisions of the Master Lease regarding signage. No alterations shall be made to the Subleased Premises by Sublessee without Sublessor’s prior approval which approval shall be given or withheld in accordance with the Master Lease;
provided, however, that Sublessor shall have the right to require that any signage installed by Sublessee be removed at the end of the Term. 

12. This Sublease is and shall be binding upon, and shall inure to the benefit of, all parties hereto by whatever names known, and to their
beneficiaries, assigns and heirs. 
 13. This Sublease may not be altered, amended, modified, or otherwise changed in any respect whatsoever
except by a writing duly executed by the parties or their authorized representatives. 
 14. This Sublease may be executed in duplicate
originals, and by counterparts, each of which is equally admissible in evidence, and each original shall fully bind each party who has executed it. Facsimile signatures and PDF format signatures sent by electronic mail shall be treated and have the
same effect as original signatures. 
 15. In the event of legal action or litigation concerning the subject matter of this Sublease, the
prevailing party shall be entitled to recover reasonable attorney’s fees and all other costs and expenses associated with the proceeding, including without limitation reasonable attorneys’ fees and other costs and expenses associated with
the collection or enforcement of any judgment. 
 16. This Sublease constitutes the entire agreement between the parties pertaining to the
subject matter contained in it and supersedes all prior agreements, representations, and understandings of the parties pertaining to such subject matter, whether oral or written. 

17. Any notice required or permitted hereunder shall be given in writing and shall be personally delivered or shall be delivered and deemed
received in the manner provided in the Master Lease, to Sublessor’s reception desk on the 6th floor of the Building, for notices to Sublessor, and for notices to Sublessee, to the Subleased
Premises, Attn: Frederic Kerrest. 
 18. This Sublease shall be conditioned upon receipt of Landlord’s consent to this Sublease in
writing on or prior to the Sublease Commencement Date (the “Landlord Consent”). Sublessor will use diligent good faith efforts to obtain the Landlord Consent prior to said date; provided, however, that if for any reason the Landlord
Consent is not received within thirty (30) days after the date of full execution and delivery of this Sublease by both parties, Sublessee may, but shall not be obligated to, at any time thereafter and prior to receipt of the Landlord Consent,
terminate this Sublease upon written notice to the Sublessor, in which case this Sublease shall have no further force and effect and Sublessor promptly shall refund to Sublessee all sums paid by Sublessee to Sublessor in connection with
Sublessee’s execution of this Sublease. 
 19. The provisions of the Master Lease are hereby deemed to be part of or incorporated into
this Sublease, and shall be applicable provisions with respect to the relationship between Sublessor and Sublessee created by this Sublease, subject to the following; (a) The term “premises” (or word of similar import) as used in the

(or words of similar import) as used in the Master Lease shall mean the Sublease Commencement Date and Sublease Expiration Date, respectively, as defined in this Sublease; and the terms Landlord and Tenant shall mean Sublessor and Sublessee,
respectively. Notwithstanding the foregoing, the following provisions of the Master Lease are not incorporated into this Sublease: Summary of Basic Lease Information Sections 3.1,3.2,3.4,4.1,4.2,6, 8,10,12 and 13; Sections 1.1.1 through 1.1.3 (with

Sublease, the latter shall control. This Sublease is subject and subordinate to the Master Lease. Subject to the provisions of Section 22.B. below, if the Master Lease terminates (including, without limitation, upon the occurrence of any
casualty or condemnation pertaining to the Subleased Premises or the Building) this Sublease shall terminate. 
 20. Sublessor represents
and warrants to Sublessee that (a) a true and complete copy of the Master Lease is attached hereto as Exhibit A and to Sublessor’s actual knowledge the Master Lease is currently in full force and effect and has not been modified,
amended or supplemented; and (b) to Sublessor’s actual knowledge neither Landlord nor Sublessor is in breach or default under the Master Lease nor is there any fact or circumstance which (with the passage of time or the giving of notice or
both) might ripen into a breach or default thereunder. 
 21. Upon the surrender of the Subleased Premises, Sublessee shall remove any
Alterations installed in the Subleased Premises by Sublessee pursuant to the Existing Agreements or this Sublease, subject to the provisions of Section 8.5 of the Lease, and repair any damage caused by such removal. In no event shall Sublessee
be obligated to remove any alterations, additions or improvements installed in the Subleased Premises by Sublessor or any predecessor-in-interest of Sublessor prior to Sublessee’s occupancy of the Subleased Premises. Subject to the foregoing
provisions, Sublessee shall be responsible for delivering the Subleased Premises to Landlord upon expiration or earlier termination of this Sublease in the condition required under the Master Lease, including without limitation the restoration of
the stairwell between the 5th and 6th floors of the Building. 

22. A. Sublessor agrees to pay all rent payable under the Master Lease to Landlord in accordance with the terms of the Master Lease and
otherwise perform its obligations under the Master Lease except to the extent Sublessee expressly agrees to perform such obligations pursuant to the terms hereof. Sublessor shall deliver promptly to Sublessee copies of all notices Sublessor receives
from Landlord with respect to the Master Lease and/or the 

  
 7 

 
Subleased Premises. With respect to work, services, repairs, restoration, provision of insurance or the performance of any other obligation of Landlord under the Master Lease, Sublessor shall use
commercially reasonable good faith efforts to obtain Landlord’s performance thereof at not more than a nominal cost to Sublessor. If Landlord fails to perform any obligation of Landlord under the Master Lease, Sublessee shall so notify
Sublessor in writing, and Sublessor shall use diligent, good faith efforts to obtain Landlord’s performance. If, after receipt of written request from Sublessee, Sublessor shall fail or refuse to take action for the enforcement of
Sublessor’s rights against Landlord with respect to the Subleased Premises (“Action”), or if Landlord shall fail or refuse to perform, Sublessee shall have the right to take such Action in its own name, and for that purpose and only
to such extent, all of the rights of Sublessor as Lessee under the Master Lease hereby are conferred upon and assigned to Sublessee, and Sublessee hereby is subrogated to such rights to the extent that the same shall apply to the Subleased Premises.
Sublessee shall give Sublessor prompt notice of all actions and activities taken by Sublessee in pursuit of the Action, and Sublessor shall have the right to approve all such actions and activities, such approval not to be unreasonably withheld. All
such actions and activities shall be at Sublessee’s sole cost and expense. If any such Action against Landlord in Sublessee’s name shall be barred by reason of lack of privity, nonassignability or otherwise, Sublessee may take such Action
in Sublessor’s name; provided that Sublessee has obtained the prior written consent of Sublessor, which consent shall not be unreasonably withheld, and, provided further, that Sublessee shall indemnify, protect, defend by counsel reasonably
satisfactory to Sublessor and hold Sublessor harmless from and against any and all liability, loss, claims, demands, suits, penalties or damage (including, without being limited to, reasonable attorneys’ fees and expenses) which Sublessor may
incur or suffer by reason of such Action, except for any such liability, loss, claims, demands, suits, penalties or damage which Sublessor may incur or suffer by reason of Sublessor’s negligent acts or omissions. 

B. If this Sublease is terminated solely as a result of a default by Sublessor under the Master Lease or this Sublease (which default is not
due to Sublessee), Sublessor shall indemnify, protect, defend with counsel reasonably acceptable to Sublessee and hold Sublessee harmless from and against any and all claims, liabilities, judgments, causes of action, damages, costs and expenses
(including reasonable attorneys’ and experts’ fees) caused by or arising in connection with Sublessor’s default and resultant termination of this Sublease; provided, however, that such indemnity shall be limited to (i) any
operating or similar costs or expenses Sublessee reasonably pays with respect to a replacement premises to the extent such costs or expenses exceed those which are allocated to Sublessee under this Sublease, (ii) any rent for comparable space
(quality, size) in excess of that due under this Sublease which Sublessee may incur should Sublessee reasonably be required to obtain substitute space following eviction from the Subleased Premises by Landlord, (iii) reasonable, actually
incurred moving expenses, and (iv) reasonable, actually incurred broker expenses and attorneys’ fees. In the event Sublessee is evicted from the Subleased Premises due to a Sublessor default of the Master Lease, Sublessee shall have the
right to use the furniture/personal property listed in Exhibit B at Sublessee’s replacement premises. The foregoing indemnity shall survive the expiration or earlier termination of this Sublease. In addition, Sublessor shall not
voluntarily terminate the Master Lease during the Term unless and until Landlord has agreed in writing to continue this Sublease in full force and effect as a direct lease between Landlord and Sublessee upon and subject to all of the terms,
covenants and conditions of this Sublease for the balance of the Term hereof. If Landlord so consents, Sublessee shall attorn to Landlord in connection with any such voluntary 

  
 8 

 
termination and shall execute an attornment agreement in such form as may reasonably be requested by Landlord; provided, however, that the attornment agreement does not materially adversely
affect the use by Sublessee of the Subleased Premises in accordance with the terms of this Sublease, materially increase Sublessee’s obligations under this Sublease or materially decrease Sublessee’s rights under this Sublease. 

C. Sublessee shall peacefully have, hold and enjoy the Subleased Premises, subject to the terms and conditions of this Sublease, provided that
Sublessee pays all rent and performs all of Sublessee’s covenants and agreements contained therein. In the event, however, that Sublessor defaults in the performance or observance of any of Sublessor’s obligations under the Master Lease to
the extent not made the obligation of Sublessee hereunder, or fails to perform Sublessor’s stated obligations under this Sublease to enforce, for Sublessee’s benefit, Landlord’s obligations under the Master Lease, then Sublessee shall
give Sublessor notice specifying in what manner Sublessor has defaulted, and if such default shall not be cured by Sublessor within thirty (30) days thereafter (except that if such default cannot be cured within said thirty (30)-day period,
this period shall be extended for an additional reasonable time, provided that Sublessor commences to cure such default within such thirty (30)-day period and proceeds diligently thereafter to effect such cure as quickly as possible), then in
addition, Sublessee shall be entitled, at Sublessee’s option, to cure such default and promptly collect from Sublessor Sublessee’s reasonable expenses in so doing (including, without limitation, reasonable attorneys’ fees and court
costs). Sublessee shall not be required, however, to wait the entire cure period described herein if earlier action is required to comply with the Master Lease or with any applicable governmental law, regulation or order. 

D. Sublessor and Landlord shall not amend or modify the Master Lease in any way so as to materially or adversely affect Sublessee or its
interest hereunder, materially increase Sublessee’s obligations hereunder or materially restrict Sublessee’s rights hereunder, without the prior written consent of Sublessee, which may be withheld in Sublessee’s sole discretion. 

E. Sublessor hereby acknowledges that Sublessor’s failure to pay the rent and other sums owing by Sublessor to Landlord under the Master
Lease will cause Sublessee to incur damages, costs and expenses not contemplated by this Sublease, especially in those cases where Sublessee has paid sums to Sublessor hereunder which correspond in whole or in part to the amounts owing by Sublessor
to Landlord under the Master Lease. Accordingly, Sublessee shall have the right to pay all rent and other sums owing by Sublessee to Sublessor hereunder for those items which also are owed by Sublessor to Landlord under this Sublease directly to
Landlord on the following terms and conditions: (i) Sublessee reasonably believes that Sublessor has failed to make any payment required to be made by Sublessor to Landlord under the Master Lease and Sublessor fails to provide adequate proof of
payment within two (2) business days after Sublessee’s written demand requesting such proof; (ii) Sublessee shall not prepay any amounts owing by Sublessee without the consent of Sublessor; (iii) Sublessee shall provide to
Sublessor concurrently with any payment to Landlord reasonable evidence of such payment; and (iv) if Sublessor notifies Sublessee that it disputes any amount demanded by Landlord, Sublessee shall not make any such payment to Landlord unless
Landlord has provided a three-day notice to pay such amount or forfeit the Master Lease.

 ARTICLE 1 

PREMISES, BUILDING, PROJECT, AND COMMON AREAS 

1.1 Premises, Building, Project and Common Areas. 

1.1.1 The Premises. Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the premises set forth in
Section 2.2 of the Summary (the “Premises”). The outline of the Initial Premises is set forth in Exhibit A-1 attached hereto and the outline of the Must-Take Space is set forth in Exhibit A-2
attached hereto (as used herein, the term “Premises” shall refer to both the Initial Premises and the Must-Take Space). Each floor or floors of the Premises has the number of rentable square feet as set forth in Section 2.2 of
the Summary. The parties hereto agree that the lease of the Premises is upon and subject to the terms, covenants and conditions (the “TCCs”) herein set forth, and Tenant covenants as a material part of the consideration for this
Lease to keep and perform each and all of such TCCs by it to be kept and performed and that this Lease is made upon the condition of such performance. The parties hereto hereby acknowledge that the purpose of Exhibit A is to show the
approximate location of the Premises in the “Building,” as that term is defined in Section 1.1.2, below, only, and such Exhibit is not meant to constitute an agreement, representation or warranty as to the construction
of the Premises, the precise area thereof or the specific location of the “Common Areas,” as that term is defined in Section 1.1.3, below, or the elements thereof or of the access ways to the Premises or the
“Project,” as that term is defined in Section 1.1.2, below. Except as specifically set forth in this Lease and in the Work Letter attached hereto as Exhibit B (the “Work Letter”), Landlord
shall not be obligated to provide or pay for any improvement work or services related to the improvement of the Premises. Tenant also acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty regarding the
condition of the Premises, the Building or the Project or with respect to the suitability of any of the foregoing for the conduct of Tenant’s business, except as specifically set forth in this Lease and the Work Letter. The taking of possession
of the Premises by Tenant shall conclusively establish that the Premises and the Building were at such time in good and sanitary order, condition and repair. 

1.1.2 The Building and The Project. The Premises is a part of the building set forth in Section 2.1 of the Summary
(the “Building”). The Building is the principal component of an office project known as “301 Brannan Street.” The term “Project,” as used in this Lease, shall mean (i) the Building and the
Common Areas, and (ii) the land (which is improved with landscaping, parking facilities and other improvements) upon which the Building and the Common Areas are located. 

1.1.3 Common Areas. Tenant shall have the non-exclusive right to use in common with other tenants in the Project, and subject to
the rules and regulations referred to in Article 5 of this Lease, those portions of the Project which are provided, from time to time, for use in common by Landlord, Tenant and any other tenants of the Project (such areas, together with such
other portions of the Project designated by Landlord, in its discretion, including certain areas designated for the exclusive use of certain tenants, or to be shared by Landlord and certain tenants, are collectively referred to herein as the
“Common Areas”). The Common Areas shall consist of the “Project Common Areas” and the “Building Common Areas” (as both of those terms are defined below). The term “Project Common
Areas,” as used in this Lease, shall mean

the portion of the Project designated as such by Landlord. The term “Building Common Areas,” as used in this Lease, shall mean the portions of the Common Areas located within the
Building designated as such by Landlord. The Common Areas shall include, without limitation, common utilities and communications closets, conduits and chases, public or common lobbies, hallways, stairways, elevators and common walkways, and if the
portion of the Premises on any floor includes less than the entire floor, then the common toilets, corridors and elevator lobby of such floor, as well as the loading areas, pedestrian sidewalks, landscaped areas, trash enclosures and other areas or
facilities, if any, which are located in or on the Property. The manner in which the Common Areas are maintained and operated shall be at the reasonable discretion of Landlord (but shall at least be consistent with the manner in which the common
areas of the “Comparable Buildings” (as that term is defined in Exhibit H to this Lease) are maintained and operated) and the use thereof shall be subject to such rules, regulations and restrictions as Landlord may make from
time to time, provided that such rules, regulations and restrictions do not unreasonably interfere with the rights granted to Tenant under this Lease and the permitted use granted under Section 5.1, below. Landlord reserves the right to
close temporarily, make alterations or additions to, or change the location of elements of the Project and the Common Areas; provided that no such changes shall be permitted which materially reduce Tenant’s rights or access hereunder. Except
when and where Tenant’s right of access is specifically excluded in this Lease, Tenant shall have the right of access to the Premises, the Building, and the Project parking facility twenty-four (24) hours per day, seven (7) days per
week during the “Lease Term,” as that term is defined in Section 2.1, below.

As of the Must-Take Lease Commencement Date, the Premises shall be expanded to include the rentable square footage of the “Must-Take Space,” as that term is defined in Section 1.1.4.1. below, as set forth in this
Section 1.1.4 and this Lease. 
 1.1.4.1 Description of the Must-Take Space. The “Must-Take
Space,” as used in this Lease, shall consist of the office space set forth in Section 2.2 of the Summary. 

1.1.4.2 Delivery of the Must-Take Space. Notwithstanding anything in this Lease to the contrary, Tenant hereby
acknowledges that Landlord shall deliver the Must-Take Space to Tenant, and Tenant shall accept delivery of the Must-Take Space from Landlord, on the Must-Take Lease Commencement Date, as set forth in Section 3.2 of the Summary. Upon the
Must-Take Lease Commencement Date, Landlord shall deliver, and Tenant shall accept, the Must Take Space in its currently existing “as is” condition, subject to reasonable wear and tear that occurs following the full execution and delivery

 1.1.4.3 Rent and Term. The Must-Take Space shall become part of the Premises for all purposes
hereunder, and, except as otherwise provided in this Section 1.1.4, shall be subject to every term and condition of this Lease and accordingly, the base rent and additional rent for the Must-Take Space shall be at the same rate, and
shall thereafter be escalated in the same manner, as the then current “Base Rent” and “Additional Rent,” as those terms are defined in Article 3 and Section 4.1 of this Lease, respectively, for the Initial
Premises, as such Base Rent and Additional Rent are adjusted and escalated pursuant to the terms of this Lease. Furthermore, for purposes of

calculating Tenant’s obligations under Article 4 of this Lease, Tenant’s Share of Building Direct Expenses shall be as set forth in Section 6 of the Summary;
provided, however, the Base Year applicable to the Must Take Space shall be as set forth in Section 5 of the Summary with respect to the Must Take Space. The lease term for the Must-Take Space shall commence, and, as set forth in
Section 4 of the Summary, Tenant shall commence payment of the Base Rent and the Additional Rent for the Must-Take Space, upon the Must Take Commencement Date, and the lease term for the Must-Take Space shall expire upon the Lease
Expiration Date. 
 1.1.4.4 Improvement of Must-Take Space. Subject to the terms of the Work Letter, Tenant
shall accept the Must-Take Space in its then existing “as is” condition. 
 1.1.4.5 Other Terms.
Except as specifically set forth in this Lease, as of the Must-Take Space Commencement Date, all other terms of this Lease shall apply to the Must-Take Space as though the Must-Take Space was originally part of the Premises. At any time after the
Must-Take Space Commencement Date during the remainder of the Lease Term, Landlord may deliver to Tenant a notice in the form of Exhibit F attached hereto, as a confirmation only of the information set forth therein, which Tenant shall
execute and return to Landlord within five (5) days of receipt thereof. 
 1.2 Stipulation of Rentable Square Feet of Premises
and Building. For purposes of this Lease, “rentable square feet” and “usable square feet” of the Premises and the Building, as the case may be, shall be shall be calculated pursuant to the Standard Method of Measuring
Floor Area in Office Buildings, ANSI Z65 - 1996, and its accompanying guidelines (collectively, “BOMA”). Landlord and Tenant hereby stipulate and agree that the rentable area of the Building is as set forth in
Section 2.1 of the Summary, and the rentable area of the Premises is as set forth in Section 2.2 of the Summary. 

1.3 Right of First Offer. 

1.3.1 In General. During the initial Lease Term, Landlord grants the original tenant named in this Lease (the “Original
Tenant”) and any Permitted Transferee, an ongoing right of first offer with respect to any space that becomes available for lease on the ground floor of the Building (the “First Offer Space”). Notwithstanding the foregoing,
such first offer right of Tenant shall be subject to the rights of any existing tenant of the First Offer Space to renew or extend the term of its lease, 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 First Offer Space, collectively, the “ROFO Superior Right Holders”). In addition, if Tenant, following its receipt of a “First
Offer Notice,” as that term is defined in Section 1.3.2 of this Lease, below, fails to exercise its right to lease all or any portion of the First Offer Space, then Landlord shall have a right to enter into an interim lease (an
“Interim Lease”) with a third party with respect to such space (i.e., the space set forth in the First Offer Notice), and Tenant’s right of first offer as set forth in this Section 1.3 shall be subordinate to all of
the rights of the tenant under the Interim Lease with respect to (i) any renewal or extension of any Interim Lease for the First Offer Space, irrespective of whether any such renewals or extensions are pursuant to existing rights in such lease
or subsequently granted rights or agreements, and 

  

					
		 	-8-	 	 KILROY REALTY

301 BRANNAN STREET
 [StumbleUpon,
Inc.]

 
regardless of whether such renewals or extensions are consummated pursuant to a lease amendment or a new lease, and (ii) any expansion rights which were set forth in the “First Offer
Notice” (as that term is defined in Section 1.3.2 below), irrespective of whether such expansion rights are pursuant to existing rights in such lease or subsequently granted rights or agreements, and regardless of whether such
expansion is consummated pursuant to a lease amendment or a new lease, and such tenant shall be deemed a ROFO Superior Right Holder solely with respect to the rights described in the foregoing items (i) and (ii). 

1.3.2 Procedure for Offer. Landlord shall notify Tenant in writing (the “First Offer Notice”) when and if the
First Offer Space or any portion thereof becomes available for lease to third parties, as determined by Landlord, provided that no ROFO Superior Right Holder wishes to lease such space. Pursuant to such First Offer Notice, Landlord shall offer to
lease to Tenant the First Offer Space. A First Offer Notice shall describe the First Offer Space so offered to Tenant and shall set forth the Base Rent payable by Tenant for the First Offer Space, the lease term for the First Offer Space (including
the anticipated “First Offer Commencement Date,” as that term is defined in Section 1.3.5 below), and the other economic terms upon which Landlord is willing to lease the First Offer Space to Tenant. 

1.3.3 Procedure for Acceptance. If Tenant wishes to exercise Tenant’s right of first offer with respect to the space
described in a First Offer Notice, then within five (5) business days of delivery of such First Offer Notice to Tenant, Tenant shall deliver notice to Landlord of Tenant’s irrevocable exercise of its right of first offer with respect to
the entire space described in such First Offer Notice on the terms contained therein. If Tenant does not notify Landlord within the five (5) business day period set forth above, then Landlord shall be free to lease the space described in the
First Offer Notice to anyone to whom Landlord desires on any “Economic Terms” (as that term is defined below) Landlord desires, provided, however, if Landlord (A) has not entered into a lease with respect to such First Offer Space
within one hundred eighty (180) days after the date of the First Offer Notice, or (B) desires to enter into a lease of such First Offer Space with a third party on Economic Terms that are more than ten percent (10%) more favorable to
such third party than the most favorable Economic Terms offered by Landlord to Tenant in the First Offer Notice (with reasonable and appropriate adjustments made to such Economic Terms to account for any difference in the length of the offered lease
terms for the First Offer Space), then Landlord shall deliver another First Offer Notice to Tenant with respect to such First Offer Space (and, if applicable, such First Offer Notice to Tenant shall contain the more favorable Economic Terms) prior
to entering into a lease of such First Offer Space with a third party. Tenant shall have the same rights with respect to such First Offer Notice as it had with respect to the initial First Offer Notice. As used in this Section 1.3,
“Economic Terms” shall refer to the net, aggregated cost to Tenant or another party, on a present value basis, of the effect of the following terms for any particular First Offer Space: (i) the rental rate (including additional
rent and considering any “base year” or “expense stop” applicable thereto); (ii) the amount of any improvement allowance or the value of any work to be performed by Landlord in connection with the lease of such First Offer
Space (which amount is a deduction from the cost to Tenant or such other party); and (iii) the amount of free rent (which amount is a deduction from the cost to Tenant or such other party). Notwithstanding anything to the contrary contained
herein, Tenant must elect to exercise its right of first offer, if at all, with respect to all of the space offered by Landlord to Tenant at any particular time, and Tenant may not elect to lease only a portion thereof.

 1.3.4 Construction In First Offer Space. Tenant shall take the First Offer Space in
its then-existing “as is” condition. The construction of improvements in the First Offer Space shall comply with the terms of Article 8 of this Lease. 

1.3.5 Amendment to Lease. If Tenant timely exercises Tenant’s right to lease First Offer Space as set forth herein, then
within fifteen (15) days thereafter, Landlord and Tenant shall execute an amendment to this Lease or a separate lease for such First Offer Space upon the terms and conditions as set forth in the First Offer Notice and this
Section 1.3.5. Notwithstanding the foregoing, an otherwise valid exercise of Tenant’s right of first offer shall be of full force and effect irrespective of whether such amendment or new lease is timely signed by Landlord and
Tenant. Tenant shall commence payment of Rent for the First Offer Space, and the term of the First Offer Space shall commence upon the date of delivery of the First Offer Space to Tenant (the “First Offer Commencement Date”) and
shall terminate upon the date set forth in the First Offer Notice (the period commencing on the First Offer Commencement Date and ending upon the date set forth in the First Offer Notice shall be referred to herein as the “First Offer
Term”). 
 1.3.6 Termination of Right of First Offer. The rights contained in this Section 1.3 shall be
personal to the Original Tenant and any Permitted Transferee, and may only be exercised by the Original Tenant and any Permitted Transferee (and not by any other assignee, sublessee or other transferee of Tenant’s interest in the Lease) if the
Original Tenant occupies at least three (3) full floors in the Building (whether under this Lease and/or the existing “Sublease” (as that term is defined in Section 2.1 below)) as of the date of the attempted exercise of
the right of first offer by Tenant and as of the scheduled date of delivery of such First Offer Space to Tenant. Tenant shall not have the right to lease First Offer Space, as provided in this Section 1.3, if, as of the date of the
attempted exercise of any right of first offer by Tenant, or, as of the scheduled date of delivery of such First Offer Space to Tenant, Tenant is in default under this Lease beyond the applicable notice and cure periods provided in this Lease or
Tenant has previously been in default under this Lease beyond any applicable notice and cure period set forth in this Lease more than once during the prior twelve (12) month period. 

ARTICLE 2 

LEASE TERM; OPTION TERM 

2.1 Lease Term. The TCCs and provisions of this Lease shall be effective as of the date of this Lease. The term of this Lease
(the “Lease Term”) shall be as set forth in Section 3.1 of the Summary, shall commence on the date set forth in Section 3.2 of the Summary (the “Initial Lease Commencement Date”), and shall
terminate on the date set forth in Section 3.3 of the Summary (the “Lease Expiration Date”) unless this Lease is sooner terminated as hereinafter provided. Tenant shall have the right to occupy the Initial Premises for
the conduct of Tenant’s business prior to the Initial Lease Commencement Date, provided that (i) Tenant shall give Landlord at least five (5) days’ prior notice of any such occupancy of the Initial Premises, (ii) a
certificate of occupancy, temporary certificate of occupancy, or its legal equivalent shall have been issued by the appropriate governmental authorities for the Initial Premises, and (iii) all of the terms and conditions of this Lease shall
apply, other than Tenant’s obligation to pay “Rent” (as that term is defined below), as though the Initial Lease Commencement Date had 

  

					
		 	-10-	 	 KILROY REALTY

 [StumbleUpon,

occurred (although the Initial Lease Commencement Date shall not actually occur until the occurrence of the same pursuant to the terms of Section 3.2 of the Summary) upon such
occupancy of the Initial Premises by Tenant. Tenant acknowledges that Tenant currently occupies the Must-Take Space pursuant to that certain Sublease dated as of December 8, 2010, as amended by the certain First Amendment to Sublease dated as
of June 23, 2011 (together, the “Sublease”) by and between Slide, Inc., a Delaware corporation, as predecessor-in-interest to Google, Inc., a Delaware corporation (“Sublandlord”), as sublandlord, and Tenant, as
subtenant. The term of the Sublease of the Must-Take Space is scheduled to expire on May 31, 2014. The term of Sublandlord’s lease of the Must-Take Space is scheduled to expire on June 30, 2014, which is after the expiration of the
Sublease but prior to the Must-Take Lease Commencement Date. Accordingly, Tenant hereby agrees that (i) Tenant shall be solely responsible for making arrangements with Sublandlord regarding Tenant’s continued occupancy of the Must-Take
Space prior to the Must-Take Lease Commencement Date, and (ii) if Landlord does not tender possession of the Must-Take Space to Tenant on or before the Must-Take Lease Commencement Date or any other particular date, for any reason whatsoever
(including, without limitation, if Sublandlord retakes possession of the Must-Take Space prior to the Must-Take Lease Commencement Date and thereafter holds over in the Must-Take Space), Landlord shall not be liable for any damage thereby, and this
Lease shall not be void or voidable thereby, in which case Base Rent shall not commence to be payable with respect to the Must-Take Space until Landlord tenders possession of the Must-Take Space to Tenant. For purposes of this Lease, the term
“Lease Year” shall mean each consecutive twelve (12) month period during the Lease Term; provided, however, that the first Lease Year shall commence on the Initial Lease Commencement Date and end on the last day of the month in
which the first anniversary of the Initial Lease Commencement Date occurs and the second and each succeeding Lease Year shall commence on the first day of the next calendar month; and further provided that the last Lease Year shall end on the Lease
Expiration Date. At any time during the Lease Term, Landlord may deliver to Tenant a notice in the form as set forth in Exhibit F, attached hereto, as a confirmation only of the information set forth therein, which Tenant shall execute
and return to Landlord within five (5) days of receipt thereof. 
 2.2 Option Term. 

2.2.1 Option Right. Landlord hereby grants the Original Tenant and its “Permitted Transferee Assignee,” as that term
is set forth in Section 14.8 of this Lease, one (1) option to extend the Lease Term for the entire Premises by a period of five (5) years (the “Option Term”). Such option shall be exercisable only by Notice
delivered by Tenant to Landlord as provided below, provided that, as of the date of delivery of such Notice, (i) Tenant is not then in default under this Lease (beyond any applicable notice and cure periods provided under this Lease),
(ii) Tenant has not been in default under this Lease (beyond any applicable notice and cure periods provided under this Lease) more than once during the prior twelve (12) month period, and (iii) Tenant has not been in default under
this Lease (beyond any applicable notice and cure periods provided under this Lease) more than three (3) times during the Lease Term. Upon the proper exercise of such option to extend, and provided that, as of the end of the Lease Term,
(A) Tenant is not in default under this Lease (beyond any applicable notice and cure periods provided under this Lease), (B) Tenant has not been in default under this Lease (beyond any applicable notice and cure periods provided under this
Lease) more than once during the prior twelve (12) month period, and (C) Tenant has not been in default under this

Lease (beyond any applicable notice and cure periods provided under this Lease) more than three (3) times during the Lease Term, then the Lease Term, as it applies to the entire Premises,
shall be extended for a period of five (5) years. The rights contained in this Section 2.2 shall only be exercised by the Original Tenant or its Permitted Transferee Assignee (and not any other assignee, sublessee or other
transferee of the Original Tenant’s interest in this Lease) if Original Tenant and/or its Permitted Transferee Assignee is in occupancy of at least three (3) full floors in the Building (whether under this Lease and/or the existing
Sublease). 
 2.2.2 Option Rent. The Rent payable by Tenant during the Option Term (the “Option Rent”) shall
be equal to the “Market Rent,” as that term is defined in, and determined pursuant to, Exhibit H attached hereto; provided, however, that the Market Rent for each Lease Year during the Option Term, shall be equal to the
amount set forth on a “Market Rate Schedule,” as that term is defined below. The “Market Rate Schedule” shall be derived from the Market Rent for the Option Term as determined pursuant to Exhibit H, attached
hereto, as follows: (i) the Market Rent for the first Lease Year of the Option Term shall be equal to the sum of (a) the Market Rent, as determined pursuant to Exhibit H, (b) the amount of Direct Expenses applicable to
the Premises, as reasonably determined by Landlord, for the calendar year in which the Option Term commences, and (c) an amount equal to the monthly amortization reimbursement payment for the “Renewal Allowance” (as defined in
Section 3 of Exhibit H to this Lease) to be paid by Landlord in connection with Tenant’s lease of the Premises for the Option Term, with such Renewal Allowance being amortized at a reasonable rate of return to Landlord
based on the rates of return then being received by the landlords of the “Comparable Buildings” as that term is set forth in Section 4 of Exhibit H attached hereto, in connection with improvement allowances then
be granted by such landlords, and (ii) the Market Rent for each subsequent Lease Year shall be equal to the prior Lease Year’s Market Rent plus an amount equal to $1.00 per rentable square foot of the Premises. 

2.2.3 Exercise of Option. The option contained in this Section 2.2 shall be exercised by Tenant, if at all, only in
the manner set forth in this Section 2.2. Tenant shall deliver notice (the “Exercise Notice”) to Landlord not more than twelve (12) months nor less than nine (9) months prior to the expiration of the initial
Lease Term or initial Option Term, as applicable, stating that Tenant is exercising its option. Concurrently with such Exercise Notice, Tenant shall deliver to Landlord Tenant’s calculation of the Market Rent (the “Tenant’s Option
Rent Calculation”). Landlord shall deliver notice (the “Landlord Response Notice”) to Tenant within thirty (30) days after receipt of Tenant’s Exercise Notice (the “Landlord Response Date”),
stating that (A) Landlord is accepting Tenant’s Option Rent Calculation as the Market Rent, or (B) rejecting Tenant’s Option Rent Calculation and setting forth Landlord’s calculation of the Market Rent (the
“Landlord’s Option Rent Calculation”). Within ten (10) business days of its receipt of the Landlord Response Notice, Tenant may, at its option, accept the Market Rent contained in the Landlord’s Option Rent
Calculation. If Tenant does not affirmatively accept or Tenant rejects the Market Rent specified in the Landlord’s Option Rent Calculation, the parties shall follow the procedure set forth in Section 2.2.4 below, and the Market Rent
shall be determined in accordance with the terms of Section 2.2.4 below. 
 2.2.4 Determination of Market Rent. In
the event Tenant objects or is deemed to have objected to the Market Rent, Landlord and Tenant shall attempt to agree upon the Market Rent using reasonable good-faith efforts. If Landlord and Tenant fail to reach

  

					
		 	-12-	 	 KILROY REALTY

301 BRANNAN STREET
 [StumbleUpon,
Inc.]

 
agreement within thirty (30) days following Tenant’s objection or deemed objection to the Landlord’s Option Rent Calculation (the “Outside Agreement Date”), then,
within two (2) business days following such Outside Agreement Date, (x) Landlord may reestablish the Landlord’s Option Rent Calculation by delivering written notice thereof to Tenant, and (y) Tenant may reestablish the
Tenant’s Option Rent Calculation by delivering written notice thereof to Tenant. If Landlord and Tenant thereafter fail to reach agreement within seven (7) business days of the Outside Agreement Date, then in connection with the Option
Rent, Landlord’s Option Rent Calculation and Tenant’s Option Rent Calculation, each as most recently delivered to the other party pursuant to the TCCs of this Section 2.2, shall be submitted to the “Neutral
Arbitrator,” as that term is defined in Section 2.2.4.1 of this Lease, pursuant to the TCCs of this Section 2.2.4. The submittals shall be made concurrently with the selection of the Neutral Arbitrator pursuant to this
Section 2.2.4 and shall be submitted to arbitration in accordance with Section 2.2.4.1 through 2.2.4.4 of this Lease, but subject to the conditions, when appropriate, of Section 2.2.3. 

2.2.4.1 Landlord and Tenant shall mutually and reasonably appoint one (1) arbitrator who shall by profession be a real
estate broker, appraiser or attorney who shall have been active over the five (5) year period ending on the date of such appointment in the leasing (or appraisal, as the case may be) of first-class, institutionally-owned, comparable commercial
properties in the Comparable Area (the “Neutral Arbitrator”). The determination of the Neutral Arbitrator shall be limited solely to the issue of whether Landlord’s Option Rent Calculation or Tenant’s Option Rent
Calculation, each as submitted to the Neutral Arbitrator pursuant to Section 2.2.4, above, is the closest to the actual Market Rent as determined by such Neutral Arbitrator, taking into account the requirements of
Section 2.2.2 of this Lease. Such Neutral Arbitrator shall be appointed within fifteen (15) days after the applicable Outside Agreement Date. Neither the Landlord or Tenant or either party’s arbitrator may, directly or
indirectly, consult with the Neutral Arbitrator prior to, or subsequent to, his or her appearance. The Neutral Arbitrator shall be retained via an engagement letter jointly prepared by Landlord’s counsel and Tenant’s counsel. 

2.2.4.2 The Neutral Arbitrator shall, within thirty (30) days of his/her appointment, reach a decision as to Market Rent
and determine whether the Landlord’s Option Rent Calculation or Tenant’s Option Rent Calculation, each as submitted to the Neutral Arbitrator pursuant to Section 2.2.4, above, is closest to Market Rent as determined by such
Neutral Arbitrator and simultaneously publish a ruling (“Award”) indicating whether Landlord’s Option Rent Calculation or Tenant’s Option Rent Calculation is closest to the Market Rent as determined by such Neutral
Arbitrator. Following notification of the Award, the Landlord’s Option Rent Calculation or Tenant’s Option Rent Calculation, whichever is selected by the Neutral Arbitrator as being closest to Market Rent, shall become the then applicable
Option Rent. 
 2.2.4.3 The Award issued by such Neutral Arbitrator shall be binding upon Landlord and Tenant. 

2.2.4.4 If Landlord and Tenant fail to appoint the Neutral Arbitrator within fifteen (15) days after the applicable
Outside Agreement Date, either

party may petition the presiding judge of the Superior Court of San Francisco County to appoint such Neutral Arbitrator subject to the criteria in Section 2.2.4.1 of this Lease, or if
he or she refuses to act, either party may petition any judge having jurisdiction over the parties to appoint such Neutral Arbitrator. 
 The cost of the
Neutral Arbitrator shall be paid by Landlord and Tenant equally. 
 ARTICLE 3 

BASE RENT 
 3.1
In General. Tenant shall pay, without prior notice or demand, to Landlord or Landlord’s agent at the management office of the Project, or, at Landlord’s option, at such other place as Landlord may from time to time designate
in writing, by a check for currency which, at the time of payment, is legal tender for private or public debts in the United States of America, base rent (“Base Rent”) as set forth in Section 4 of the Summary, payable in
equal monthly installments as set forth in Section 4 of the Summary in advance on or before the first day of each and every calendar month during the Lease Term, without any setoff or deduction whatsoever, except as otherwise provided in
Section 6.5 of this Lease. The Base Rent for the first full month of the Lease Term which occurs after the expiration of any free rent period shall be paid at the time of Tenant’s execution of this Lease. If any Rent payment date
(including the Lease Commencement Date) falls on a day of the month other than the first day of such month or if any payment of Rent is for a period which is shorter than one month, the Rent for any such fractional month shall accrue on a daily
basis during such fractional month and shall total an amount equal to the product of (i) a fraction, the numerator of which is the number of days in such fractional month and the denominator of which is the actual number of days occurring in
such calendar month, and (ii) the then-applicable Monthly Installment of Base Rent. All other payments or adjustments required to be made under the TCCs of this Lease that require proration on a time basis shall be prorated on the same basis.

 3.2 Abated Base Rent. Provided that no event of monetary default (beyond any applicable notice and cure periods) is then
occurring, during the first three (3) months of the Lease Term after the Initial Lease Commencement Date (collectively, the “Rent Abatement Period”), Tenant shall not be obligated to pay any Base Rent otherwise attributable to
the Initial Premises for such Rent Abatement Period (the “Rent Abatement”). Tenant acknowledges and agrees that notwithstanding such Rent Abatement, such abatement of Base Rent shall have no effect on the calculation of any future
increases in Base Rent, Operating Expenses or Tax Expenses payable by Tenant pursuant to the terms of this Lease, which increases shall be calculated without regard to such abatement of Base Rent or corresponding abatement periods. Such Rent
Abatement has been granted to Tenant as additional consideration for entering into this Lease, and for agreeing to pay the rental and performing the terms and conditions otherwise required under this Lease. In the event of a default by Tenant under
the terms of this Lease that results in early termination pursuant to the provisions of Article 19 below, then as a part of Landlord’s exercise of its remedies as set forth in Section 19.2 below, Landlord shall be entitled to
make a claim to recover the monthly Base Rent that was abated under the provisions of this Section 3.2.

change, Tenant’s Share of Direct Expenses shall be equitably adjusted for any Expense Year involved in any such change. 
 4.2.4
“Operating Expenses” shall mean all expenses, costs and amounts of every kind and nature which Landlord pays or accrues during any Expense Year because of or in connection with the ownership, management, maintenance, security,
repair, replacement, restoration or operation of the Project, or any portion thereof, in accordance with sound real estate management and accounting principles, consistently applied. Without limiting the generality of the foregoing, Operating

the Project vis-a-vis the square footage of other projects also managed from such management office space); (viii) wages, salaries and other compensation and benefits, including taxes levied thereon, of all persons (other than persons generally
considered to be higher in rank than the position of “Senior Asset Manager”) engaged in the operation, maintenance and security of the Project; (ix) costs under any instrument pertaining to the sharing of costs by the Project,

in the operation or maintenance of the Project, to the extent of cost savings reasonably anticipated by Landlord at the time of such expenditure to be incurred in connection therewith, (B) that are required to comply with present or anticipated
conservation programs or to otherwise further sustainability measures, or (C) that are required under any governmental law or regulation by a federal, state or local governmental agency, except for capital repairs, replacements or other
improvements to remedy a condition existing prior to the Lease Commencement Date which an applicable governmental authority, if it had knowledge of such condition prior to the Lease Commencement Date, would have then required to be remedied pursuant
to then-current governmental laws or regulations in their form existing as of the Lease Commencement Date and pursuant to the then-current interpretation of such governmental laws or regulations by the applicable governmental authority as of the
Lease Commencement Date; provided, however, that any capital expenditure shall be amortized with interest at the Interest Rate over (X) its useful life as Landlord shall reasonably determine in accordance with sound real estate management and
accounting principles, or (Y) with respect to those items included under item (A) above, their recovery/payback period as Landlord shall reasonably determine in accordance with sound real estate management and accounting principles;

(e) costs associated with the operation of the business of the partnership or entity which constitutes the Landlord, as the same are

or entity which constitutes the Landlord include costs of partnership accounting and legal matters, costs of defending any lawsuits with any mortgagee (except as the actions of the Tenant may be in issue), costs of selling, syndicating, financing,
mortgaging or hypothecating any of the Landlord’s interest in the Project, and costs incurred in connection with any disputes between Landlord and its employees, between Landlord and Project management, or between Landlord and other tenants or
occupants, and Landlord’s general corporate overhead and general and administrative expenses; 
 (f) the wages and benefits of any
employee who does not devote substantially all of his or her employed time to the Project unless such wages and benefits are prorated to reflect time spent on operating and managing the Project vis-a-vis time spent on matters unrelated to operating

however, that in no event shall Operating Expenses for purposes of this Lease include wages and/or benefits attributable to personnel above the level of Senior Asset Manager;

 If Landlord is not furnishing any particular work or service (the cost of which, if performed by
Landlord, would be included in Operating Expenses) to a tenant who has undertaken to perform such work or service in lieu of the performance thereof by Landlord, Operating Expenses shall be deemed to be increased by an amount equal to the additional
Operating Expenses which would reasonably have been incurred during such period by Landlord if it had at its own expense furnished such work or service to such tenant. If the Project is not at least ninety-five percent (95%) occupied during all
or a portion of the Base Year or any Expense Year, Landlord may elect to make an appropriate adjustment to the components of Operating Expenses for such year to determine the amount of Operating Expenses that would have been incurred had the Project
been ninety-five percent (95%) occupied; and the amount so determined shall be deemed to have been the amount of Operating Expenses for such year. Notwithstanding anything to the contrary set forth in this Article 4, Operating Expenses
for the Base Year shall include market-wide cost increases (including utility rate increases) due to extraordinary circumstances, including, but not limited to, Force Majeure, boycotts, strikes, conservation surcharges, embargoes or shortages, or
amortized costs; provided, however, that at such time as any such increases in such particular charges, costs or fees are no longer included in Operating Expenses, such increases in such particular charges, costs or fees shall be excluded from the
Base Year calculation of Operating Expenses. In no event shall the components of Direct Expenses for any Expense Year related to Tax Expenses be less than the corresponding components of Direct Expenses related to Tax Expenses in the Base Year.
Landlord shall not (i) make a profit by charging items to Operating Expenses that are otherwise also charged separately to others and (ii) subject to Landlord’s right to adjust the components of Operating Expenses described above in
this paragraph, collect Operating Expenses from Tenant and all other tenants in the Building in an amount in excess of what Landlord incurs for the items included in Operating Expenses. 

4.2.5 Taxes. 

4.2.5.1 “Tax Expenses” shall mean all federal, state, county, or local governmental or municipal taxes, fees,
charges or other impositions of every kind and nature, whether general, special, ordinary or extraordinary, (including, without limitation, real estate taxes, general and special assessments, transit taxes, leasehold taxes or taxes based upon the
receipt of rent, including gross receipts or sales taxes applicable to the receipt of rent, unless required to be paid by Tenant, personal property taxes imposed upon the fixtures, machinery, equipment, apparatus, systems and equipment,
appurtenances, furniture and other personal property used in connection with the Project, or any portion thereof), which shall accrue during any Expense Year (without regard to any different fiscal year used by such governmental or municipal
authority) because of or in connection with the ownership, leasing and operation of the Project, or any portion thereof. Tax Expenses for any Expense Year (including a Base Year) shall reflect any reassessment under Proposition 13 as a result of any
sale, refinancing or change in ownership of the Project (including, without limitation, the 2011 acquisition of the Project by the Landlord originally named herein); provided that, if any such reassessment has not occurred as of the end of any
Expense Year (including a Base Year), then 

  

					
		 	-19-	 	 KILROY REALTY

301 BRANNAN STREET
 [StumbleUpon,

Landlord shall retroactively recalculate Tax Expenses for such Expense Year to include any increases in Tax Expenses as a result of such reassessment once such reassessment has occurred. 

4.2.5.2 Tax Expenses shall include, without limitation: (i) Any tax on the rent, right to rent or other income from the
Project, or any portion thereof, or as against the business of leasing the Project, or any portion thereof; (ii) Any assessment, tax, fee, levy or charge in addition to, or in substitution, partially or totally, of any assessment, tax, fee,
levy or charge previously included within the definition of real property tax, it being acknowledged by Tenant and Landlord that Proposition 13 was adopted by the voters of the State of California in the June 1978 election
(“Proposition 13”) and that assessments, taxes, fees, levies and charges may be imposed by governmental agencies for such services as fire protection, street, sidewalk and road maintenance, refuse removal and for other
governmental services formerly provided without charge to property owners or occupants, and, in further recognition of the decrease in the level and quality of governmental services and amenities as a result of Proposition 13, Tax Expenses shall
also include any governmental or private assessments or the Project’s contribution towards a governmental or private cost-sharing agreement for the purpose of augmenting or improving the quality of services and amenities normally provided by
governmental agencies; (iii) Any assessment, tax, fee, levy, or charge allocable to or measured by the area of the Premises or the Rent payable hereunder, including, without limitation, any business or gross income tax or excise tax with
respect to the receipt of such rent, or upon or with respect to the possession, leasing, operating, management, maintenance, alteration, repair, use or occupancy by Tenant of the Premises, or any portion thereof. Any documentary transfer tax or
other similar assessment, tax, fee, levy or charge, upon the consummation of this transaction (as opposed to the Rent payable hereunder) or any document to which Landlord and Tenant are parties, creating or transferring an interest or an estate in
the Premises (as opposed to any document executed in connection with a “Transfer” as that term is defined in Section 14.1, below) shall be excluded from Tax Expenses; provided, however, Tenant shall be responsible for any rent
tax, sales tax, service tax, transfer tax, value added tax or other applicable tax on the Rent payable hereunder pursuant to Section 4.5.3 below. 

4.2.5.3 Any costs and expenses (including, without limitation, reasonable attorneys’ fees) incurred in attempting to
protest, reduce or minimize Tax Expenses shall be included in Tax Expenses in the Expense Year such expenses are paid. Except as set forth in Section 4.2.5.4, below, refunds of Tax Expenses shall be credited against Tax Expenses and
refunded to Tenant regardless of when received, based on the Expense Year to which the refund is applicable, provided that in no event shall the amount to be refunded to Tenant for any such Expense Year exceed the total amount paid as an increase in
the Tax Expenses by Tenant included as Additional Rent under this Article 4 for such Expense Year. If Tax Expenses for any period during the Lease Term or any extension thereof are increased after payment thereof for any reason, including,
without limitation, error or reassessment by applicable governmental or municipal authorities, Tenant shall pay Landlord, within thirty (30) days after request from Landlord, Tenant’s Share of any such increased Tax Expenses included by
Landlord as Building Tax Expenses pursuant to the TCCs of this Lease. Notwithstanding anything to 

  

					
		 	-20-	 	 KILROY REALTY

301 BRANNAN STREET
 [StumbleUpon,

the contrary contained in this Section 4.2.5 (except as set forth in Section 4.2.5.1, above), there shall be excluded from Tax Expenses (i) all excess profits taxes,
franchise taxes, gift taxes, capital stock taxes, inheritance and succession taxes, estate taxes, federal and state income taxes, and other taxes to the extent applicable to Landlord’s general or net income (as opposed to rents, receipts or
income attributable to operations at the Project), (ii) any items included as Operating Expenses, and (iii) any items paid by Tenant under Section 4.5 of this Lease. 

4.2.5.4 Notwithstanding anything to the contrary set forth in this Lease, the amount of Tax Expenses for the Base Year and any
Expense Year shall be calculated without taking into account any decreases in real estate taxes obtained in connection with Proposition 8, and, therefore, the Tax Expenses in the Base Year and/or an Expense Year may be greater than those actually
incurred by Landlord, but shall, nonetheless, be the Tax Expenses due under this Lease; provided that (i) any costs and expenses incurred by Landlord in securing any Proposition 8 reduction shall not be included in Direct Expenses for purposes
of this Lease, and (ii) tax refunds under Proposition 8 shall not be deducted from Tax Expenses, but rather shall be the sole property of Landlord. Landlord and Tenant acknowledge that this Section 4.2.5.4 is not intended to in any
way affect (A) the inclusion in Tax Expenses of the statutory two percent (2.0%) annual maximum allowable increase in Tax Expenses (as such statutory increase may be modified by subsequent legislation), or (B) the inclusion or
exclusion of Tax Expenses pursuant to the terms of Proposition 13, which shall be governed pursuant to the terms of Sections 4.2.5.1 through 4.2.5.3, above. 

4.2.6 “Tenant’s Share” shall mean the percentage set forth in Section 6 of the Summary. 

4.2.7 “Utilities Costs” shall mean all actual charges for utilities for the Building and the Project which Landlord shall pay
during any Expense Year, including, but not limited to, the costs of water, sewer and electricity, and the costs of HVAC (including the cost of electricity to operate the HVAC air handlers) and other utilities (but excluding those charges for which
tenants directly reimburse Landlord or otherwise pay directly to the utility company) as well as related fees, assessments and surcharges. Utilities Costs shall be calculated assuming the Buildings (and during the period of time when any other
office buildings are fully constructed and ready for occupancy and are included by Landlord within the Project), are at least ninety-five percent (95%) occupied. If, during all or any part of any Expense Year, Landlord shall not provide any
utilities other than gas and electricity (the cost of which, if provided by Landlord, would be included in Utilities Costs) to a tenant (including Tenant) who has undertaken to provide the same instead of Landlord, Utilities Costs shall be deemed to
be increased by an amount equal to the additional Utilities Costs which would reasonably have been incurred during such period by Landlord if Landlord had at its own expense provided such utilities to such tenant. Utilities Costs shall include any
costs of utilities which are allocated to the Real Property under any declaration, restrictive covenant, or other instrument pertaining to the sharing of costs by the Real Property or any portion thereof, including any covenants, conditions or
restrictions now or hereafter recorded against or affecting the Real Property. Notwithstanding anything to the contrary set forth in this Article 4, Utilities Costs for the Utilities Base Year shall not include any one time special charges,
costs or fees or extraordinary charges or costs incurred in the Utilities

Base Year only, including those attributable to boycotts, embargoes, strikes or other shortages of services or fuel; provided, however, that at such time as any such increases in such particular
charges, costs or fees are no longer included in Utilities Costs, such increases in such particular charges, costs or fees shall be excluded from the Utilities Base Year calculation of Utilities Cost. For purposes hereof, the “Utilities Base
Year” shall mean the applicable Base Year. 
 4.3 Cost Pools. Landlord shall have the right, from time to time, to
equitably allocate some or all of the Direct Expenses for the Project among different portions or occupants of the Project (the “Cost Pools”), in Landlord’s reasonable discretion. Such Cost Pools may include, but shall not be
limited to, the office space tenants of a building of the Project or of the Project, and the retail space tenants of a building of the Project or of the Project. The Direct Expenses within each such Cost Pool shall be allocated and charged to the
tenants within such Cost Pool in an equitable manner. 
 4.4 Calculation and Payment of Additional Rent. If for any Expense
Year ending or commencing within the Lease Term, Tenant’s Share of Direct Expenses for such Expense Year exceeds Tenant’s Share of Direct Expenses applicable to the Base Year, then Tenant shall pay to Landlord, in the manner set forth in
Section 4.4.1, below, and as Additional Rent, an amount equal to the excess (the “Excess”). 
 4.4.1
Statement of Actual Building Direct Expenses and Payment by Tenant. Landlord shall give to Tenant following the end of each Expense Year, a statement (the “Statement”) which shall state in general major categories the
Building Direct Expenses incurred or accrued for the Base Year or such preceding Expense Year, as applicable, and which shall indicate the amount of the Excess. Landlord shall use commercially reasonable efforts to deliver such Statement to Tenant
on or before May 1 following the end of the Expense Year to which such Statement relates. Upon receipt of the Statement for each Expense Year commencing or ending during the Lease Term, if an Excess is present, Tenant shall pay, within thirty
(30) days after receipt of the Statement, the full amount of the Excess for such Expense Year, less the amounts, if any, paid during such Expense Year as “Estimated Excess,” as that term is defined in Section 4.4.2, below,
and if Tenant paid more as Estimated Excess than the actual Excess, Tenant shall receive a credit in the amount of Tenant’s overpayment against Rent next due under this Lease. The failure of Landlord to timely furnish the Statement for any
Expense Year shall not prejudice Landlord or Tenant from enforcing its rights under this Article 4. Even though the Lease Term has expired and Tenant has vacated the Premises, when the final determination is made of Tenant’s Share of
Building Direct Expenses for the Expense Year in which this Lease terminates, if an Excess is present, Tenant shall, within thirty (30) days after receipt of the Statement, pay to Landlord such amount, and if Tenant paid more as Estimated
Excess than the actual Excess, Landlord shall, within thirty (30) days, deliver a check payable to Tenant in the amount of the overpayment. The provisions of this Section 4.4.1 shall survive the expiration or earlier termination of
the Lease Term. Notwithstanding the immediately preceding sentence, Tenant shall not be responsible for Tenant’s Share of any Building Direct Expenses attributable to any Expense Year which are first billed to Tenant more than one
(1) calendar year after the close of the applicable Expense Year, provided that in any event Tenant shall be responsible for Tenant’s Share of Direct Expenses which (x) were levied by any governmental authority or by any public
utility companies, and (y) Landlord had not previously received an invoice therefor and which are currently due and owing (i.e., costs invoiced for the first time regardless of the date when the work or service relating to this Lease was
performed), at any time following the Lease Expiration Date which are attributable to any Expense Year.

 4.4.2 Statement of Estimated Building Direct Expenses. In addition, Landlord shall
endeavor to give Tenant a yearly expense estimate statement (the “Estimate Statement”) which shall set forth in general major categories Landlord’s reasonable estimate (the “Estimate”) of what the total amount
of Building Direct Expenses for the then-current Expense Year shall be and the estimated excess (the “Estimated Excess”) as calculated by comparing the Building Direct Expenses for such Expense Year, which shall be based upon the
Estimate, to the amount of Building Direct Expenses for the Base Year. The failure of Landlord to timely furnish the Estimate Statement for any Expense Year shall not preclude Landlord from enforcing its rights to collect any Additional Rent under
this Article 4, nor shall Landlord be prohibited from revising any Estimate Statement or Estimated Excess theretofore delivered to the extent necessary. Thereafter, Tenant shall pay, within thirty (30) days after receipt of the Estimate
Statement, a fraction of the Estimated Excess for the then-current Expense Year (reduced by any amounts paid pursuant to the second to last sentence of this Section 4.4.2). Such fraction shall have as its numerator the number of months
which have elapsed in such current Expense Year, including the month of such payment, and twelve (12) as its denominator. Until a new Estimate Statement is furnished (which Landlord shall have the right to deliver to Tenant at any time), Tenant
shall pay monthly, with the monthly Base Rent installments, an amount equal to one-twelfth (1/12) of the total Estimated Excess set forth in the previous Estimate Statement delivered by Landlord to Tenant. Throughout the Lease Term Landlord
shall maintain books and records with respect to Building Direct Expenses in accordance with generally accepted real estate accounting and management practices, consistently applied. 

4.5 Taxes and Other Charges for Which Tenant Is Directly Responsible. 

4.5.1 Tenant shall be liable for and shall pay ten (10) days before delinquency, taxes levied against Tenant’s equipment, furniture,
fixtures and any other personal property located in or about the Premises. If any such taxes on Tenant’s equipment, furniture, fixtures and any other personal property are levied against Landlord or Landlord’s property or if the assessed
value of Landlord’s property is increased by the inclusion therein of a value placed upon such equipment, furniture, fixtures or any other personal property and if Landlord pays the taxes based upon such increased assessment, which Landlord
shall have the right to do regardless of the validity thereof but only under proper protest if requested by Tenant, Tenant shall upon demand repay to Landlord the taxes so levied against Landlord or the proportion of such taxes resulting from such
increase in the assessment, as the case may be. 
 4.5.2 Intentionally Omitted. 

4.5.3 Notwithstanding any contrary provision herein, Tenant shall pay prior to delinquency any (i) rent tax or sales tax, service tax,
transfer tax or value added tax, or any other applicable tax on the rent or services herein or otherwise respecting this Lease, or (ii) taxes assessed upon or with respect to the possession, leasing, operation, management, maintenance,
alteration, repair, use or occupancy by Tenant of the Premises or any portion of the Project, including the Project parking facility.

 4.6 Landlord’s Books and Records. Upon Tenant’s written request given not
more than ninety (90) days after Tenant’s receipt of a Statement for a particular Expense Year, and provided that Tenant is not then in default under this Lease beyond the applicable cure period provided in this Lease, specifically
including, but not limited to, the timely payment of Additional Rent (whether or not the same is subject of the audit contemplated herein), Landlord shall furnish Tenant with such reasonable supporting documentation in connection with said Direct
Expenses as Tenant may reasonably request. Landlord shall provide said information to Tenant within forty-five (45) days after Tenant’s written request therefor. Within one hundred eighty (180) days after receipt of a Statement by
Tenant (the “Review Period”), if Tenant disputes the amount of Additional Rent set forth in the Statement, an independent certified public accountant (which accountant (A) is a member of a nationally or regionally recognized
accounting firm which has previous experience in reviewing financial operating records of landlords of office buildings, (B) is not working on a contingency fee basis [i.e., Tenant must be billed based on the actual time and materials that are
incurred by the accounting firm in the performance of the audit], and (C) shall not currently or in the future be providing accounting and/or lease administration services to another tenant in the Building and/or the Project in connection with
a review or audit by such other tenant of Direct Expenses), designated and paid for by Tenant, may, after reasonable notice to Landlord and at reasonable times, audit Landlord’s records with respect to the Statement at Landlord’s corporate
offices, provided that (i) Tenant is not then in default under this Lease (beyond any applicable notice and cure periods provided under this Lease), (ii) Tenant has paid all amounts required to be paid under the applicable
Estimate Statement and Statement, as the case may be, and (iii) a copy of the audit agreement between Tenant and its particular auditor has been delivered to Landlord prior to the commencement of the audit. In connection with such audit,
Tenant and Tenant’s agents must agree in advance to follow Landlord’s reasonable rules and procedures regarding audits of Landlord’s records, and shall execute a commercially reasonable confidentiality agreement regarding such audit.
Any audit report prepared by Tenant’s auditors shall be delivered concurrently to Landlord and Tenant within the one hundred eighty (180) day period referenced above. Tenant’s failure to dispute the amount of Additional Rent set forth
in any Statement within the Review Period shall be deemed to be Tenant’s approval of such Statement and Tenant, thereafter, waives the right or ability to dispute the amounts set forth in such Statement. If after such audit, Tenant still
disputes such Additional Rent, an audit as to the proper amount shall be made, at Tenant’s expense, by an independent certified public accountant (the “Accountant”) selected by Landlord and subject to Tenant’s reasonable
approval; provided that if such auditing by the Accountant proves that Direct Expenses were overstated by more than five percent (5%), then the cost of the Accountant and the cost of such audit shall be paid for by Landlord, and Landlord shall,
within thirty (30) days, deliver a check payable to Tenant in the amount by which the Direct Expenses were overstated. Tenant hereby acknowledges that Tenant’s sole right to audit Landlord’s books and records and to contest the amount
of Direct Expenses payable by Tenant shall be as set forth in this Section 4.6, and Tenant hereby waives any and all other rights pursuant to applicable law to audit such books and records and/or to contest the amount of Direct Expenses
payable by Tenant.

Project or obstruct or interfere with the rights of other tenants or occupants of the Building, or injure or annoy them or use or allow the Premises to be used for any improper, unlawful or objectionable purpose, nor shall Tenant cause, maintain or
permit any nuisance in, on or about the Premises.

under the Lease and Tenant’s use of the Premises shall be subject and subordinate to, all recorded easements, covenants, conditions, and restrictions (collectively, the “CC&Rs”) hereafter affecting the Project, provided
that Landlord shall not enter into any CC&Rs affecting the Project after the date of this Lease which prevents Tenant from using, or unreasonably interferes with Tenant’s use of or access to, the Premises for the Permitted Use, or otherwise
materially adversely affects Tenant’s rights or materially increases Tenant’s costs under this Lease.

right to inspect the Premises upon reasonable notice to Tenant and to require Tenant to provide additional cleaning of the Premises, if reasonably necessary. In the event Tenant shall fail to provide any of the services described in this
Section 6.2 within thirty (30) days after written notice from Landlord, which notice shall not be required in the event of an emergency, Landlord shall have the right to provide such services and any charge or cost incurred by
Landlord in connection therewith shall be deemed Additional Rent due and payable by Tenant upon receipt by Tenant of a written statement of cost from Landlord. Failure of Tenant to comply with any one or more of the foregoing provisions shall be
deemed to be a default under this Lease. 
 6.3 Overstandard Tenant Use. Tenant shall not, without Landlord’s prior
written consent, use heat-generating machines, machines other than normal fractional horsepower office machines, or equipment or lighting other than Building standard lights in the Premises, which may affect the temperature otherwise maintained by
the air conditioning system or increase the water normally furnished for the Premises by Landlord pursuant to the terms of Section 6.1 of this Lease. If such consent is given, Landlord shall have the right to require installation of
supplementary air conditioning units or other facilities in the Premises, including supplementary or additional metering devices, and the cost thereof, including the cost of installation, operation and maintenance, increased wear and tear on
existing equipment and other similar charges, shall be paid by Tenant to Landlord upon billing by Landlord. If Tenant uses water, electricity, heat or air conditioning in excess of that supplied by Landlord pursuant to Section 6.1 of
this Lease, Tenant shall pay to Landlord, upon billing, the cost of such excess consumption, the cost of the installation, operation, and maintenance of equipment which is installed in order to supply such excess consumption, and the cost of the
increased wear and tear on existing equipment caused by such excess consumption; and Landlord may install devices to separately meter any increased use and in such event Tenant shall pay the increased cost directly to Landlord, on demand, at the
rates charged by the public utility company furnishing the same, including the cost of such additional metering devices. Tenant’s use of electricity shall never exceed the capacity of the feeders to the Project or the risers or wiring
installation, and subject to the terms of Section 29.32, below, Tenant shall not install or use or permit the installation or use of any computer server or electronic data processing equipment in the Premises to the extent such devices
may materially affect the temperature otherwise maintained by the air conditioning

system for the Premises by Landlord pursuant to the terms of Section 6.1 of this Lease, without the prior written consent of Landlord. If Tenant desires to use heat, ventilation or
air conditioning during hours other than those for which Landlord is obligated to supply such utilities pursuant to the terms of Section 6.1 of this Lease, Tenant shall give Landlord such prior notice, if any, as Landlord shall from time
to time establish as appropriate, of Tenant’s desired use in order to supply such utilities, and Landlord shall supply such utilities to Tenant at such hourly cost to Tenant (which shall be treated as Additional Rent) as Landlord shall from
time to time establish. 
 6.4 Interruption of Use. Tenant agrees that Landlord shall not be liable for damages, by abatement
of Rent or otherwise, for failure to furnish or delay in furnishing any service (including telephone and telecommunication services), or for any diminution in the quality or quantity thereof, when such failure or delay or diminution is occasioned,
in whole or in part, by breakage, repairs, replacements, or improvements, by any strike, lockout or other labor trouble, by inability to secure electricity, gas, water, or other fuel at the Building or Project after reasonable effort to do so, by
any riot or other dangerous condition, emergency, accident or casualty whatsoever, by act or default of Tenant or other parties, or by any other cause beyond Landlord’s reasonable control; and such failures or delays or diminution shall never
be deemed to constitute an eviction or disturbance of Tenant’s use and possession of the Premises or relieve Tenant from paying Rent or performing any of its obligations under this Lease, except as otherwise provided in Section 6.5
or elsewhere in the Lease. Furthermore, Landlord shall not be liable under any circumstances for a loss of, or injury to, property or for injury to, or interference with, Tenant’s business, including, without limitation, loss of profits,
however occurring, through or in connection with or incidental to a failure to furnish any of the services or utilities as set forth in this Article 6. 

6.5 Abatement of Rent. If (i) Landlord fails to perform the obligations required of Landlord under the TCCs of this Lease,
(ii) such failure causes all or a portion of the Premises to be untenantable and unusable by Tenant, and (iii) such failure relates to (A) the nonfunctioning of the heat, ventilation, and air conditioning system in the Premises, the
electricity in the Premises, the nonfunctioning of the elevator service to the Premises, or (B) a failure to provide access to the Premises, Tenant shall give Landlord notice (the “Initial Notice”), specifying such failure to
perform by Landlord (the “Abatement Event”). If Landlord has not cured such Abatement Event within three (3) business days after the receipt of the Initial Notice (the “Eligibility Period”), Tenant may deliver
an additional notice to Landlord (the “Additional Notice”), specifying such Abatement Event and Tenant’s intention to abate the payment of Rent under this Lease. If Landlord does not cure such Abatement Event within three
(3) business days of receipt of the Additional Notice, Tenant may, upon written notice to Landlord, immediately abate Rent payable under this Lease for that portion of the Premises rendered untenantable and not used by Tenant, for the period
beginning on the date three (3) business days after the Initial Notice to the earlier of the date Landlord cures such Abatement Event or the date Tenant recommences the use of such portion of the Premises. Such right to abate Rent shall be
Tenant’s sole and exclusive remedy at law or in equity for a Abatement Event. Except as provided in this Section 6.5, nothing contained herein shall be interpreted to mean that Tenant is excused from paying Rent due hereunder.

 ARTICLE 7 

REPAIRS 
 Landlord
shall maintain in first-class condition and operating order and keep in good repair and condition the structural portions of the Building, including the foundation, floor/ceiling slabs, roof structure (as opposed to roof membrane), curtain wall,
exterior glass and mullions, columns, beams, shafts (including elevator shafts), stairs, stairwells, elevator cab, men’s and women’s washrooms, Building mechanical, electrical and telephone closets, and all common and public areas
servicing the Building, including the parking areas, landscaping and exterior Project signage (collectively, “Building Structure”) and the Base Building mechanical, electrical, life safety, plumbing, sprinkler systems and HVAC
systems which were not constructed by Tenant Parties (collectively, the “Building Systems”) and the Project Common Areas. Notwithstanding anything in this Lease to the contrary, Tenant shall be required to repair the Building
Structure and/or the Building Systems to the extent caused due to Tenant’s use of the Premises for other than normal and customary business office operations, unless and to the extent such damage is covered by insurance carried or required to
be carried by Landlord pursuant to Article 10 and to which the waiver of subrogation is applicable (such obligation to the extent applicable to Tenant as qualified and conditioned will hereinafter be defined as the “BS/BS
Exception”). Tenant shall, at Tenant’s own expense, keep the Premises, including all improvements, fixtures and furnishings therein, and the floor or floors of the Building on which the Premises are located, in good order, repair and
condition at all times during the Lease Term, but such obligation shall not extend to the Building Structure and the Building Systems except pursuant to the BS/BS Exception. In addition, Tenant shall, at Tenant’s own expense, but under the
supervision and subject to the prior approval of Landlord, and within any reasonable period of time specified by Landlord, promptly and adequately repair all damage to the Premises and replace or repair all damaged, broken, or worn fixtures and
appurtenances, except for damage caused by ordinary wear and tear or beyond the reasonable control of Tenant; provided, however, that, at Landlord’s option, or if Tenant fails to make such repairs, Landlord may, after written notice to Tenant
and Tenant’s failure to repair within five (5) business days thereafter, but need not, make any repairs and replacements, and Tenant shall pay Landlord the out-of-pocket costs thereof, plus ten percent (10%) of such out-of-pocket
costs thereof to reimburse Landlord for all overhead, general conditions, fees and other costs or expenses arising from Landlord’s involvement with such repairs and replacements forthwith upon being billed for same. Subject to the terms of
Article 27 below, Landlord may, but shall not be required to, enter the Premises at all reasonable times to make such repairs, alterations, improvements or additions to the Premises or to the Project or to any equipment located in the
Project as Landlord may be allowed to do under this Lease or required to do by governmental or quasi-governmental authority or court order or decree; provided, however, except for emergencies, any such entry into the Premises by Landlord shall be
performed in a manner so as not to materially interfere with Tenant’s use of, or access to, the Premises. Tenant hereby waives any and all rights under and benefits of subsection 1 of Section 1932 and Sections 1941 and 1942 of the
California Civil Code or under any similar law, statute, or ordinance now or hereafter in effect.

 ARTICLE 8 

ADDITIONS AND ALTERATIONS 

8.1 Landlord’s Consent to Alterations. Tenant may not make any improvements, alterations, additions or changes to the
Premises or any mechanical, plumbing or HVAC facilities or systems pertaining to the Premises (collectively, the “Alterations”) without first procuring the prior written consent of Landlord to such Alterations, which consent shall
be requested by Tenant not less than fifteen (15) business days prior to the commencement thereof, and which consent shall not be unreasonably withheld by Landlord, provided it shall be deemed reasonable for Landlord to withhold its consent to
any Alteration which adversely affects the structural portions or the systems or equipment of the Building or is visible from the exterior of the Building. Notwithstanding the foregoing, Tenant shall be permitted to make Alterations following ten
(10) business days notice to Landlord, but without Landlord’s prior consent, to the extent that such Alterations do not (i) adversely affect the systems and equipment of the Building, exterior appearance of the Building, or structural
aspects of the Building, or (ii) adversely affect the value of the Premises or Building (the “Cosmetic Alterations”). The construction of the initial improvements to the Premises shall be governed by the terms of the Work
Letter and not the terms of this Article 8. 
 8.2 Manner of Construction. Landlord may impose, as a condition of its
consent to any and all Alterations or repairs of the Premises or about the Premises, such requirements as Landlord in its reasonable discretion may deem desirable, including, but not limited to, the requirement that Tenant utilize for such purposes
only contractors reasonably approved by Landlord, and the requirement that upon Landlord’s timely request (as more particularly set forth in Section 8.5, below). Tenant shall, at Tenant’s expense, remove such Alterations upon
the expiration or any early termination of the Lease Term in accordance with the terms of Section 8.5, below. If Landlord shall give its consent, the consent shall be deemed conditioned upon Tenant acquiring a permit to do the work from
appropriate governmental agencies, the furnishing of a copy of such permit to Landlord prior to the commencement of the work, and the compliance by Tenant with all conditions of said permit in a prompt and expeditious manner. If such Alterations
will involve the use of or disturb hazardous materials or substances existing in the Premises, Tenant shall comply with Landlord’s rules and regulations concerning such hazardous materials or substances. Tenant shall construct such Alterations
and perform such repairs in a good and workmanlike manner, in conformance with any and all applicable federal, state, county or municipal laws, rules and regulations and pursuant to a valid building permit, issued by the City of San Francisco, all
in conformance with Landlord’s construction rules and regulations; provided, however, that prior to commencing to construct any Alteration, Tenant shall meet with Landlord to discuss Landlord’s design parameters and code compliance issues.
In the event Tenant performs any Alterations in the Premises which require or give rise to governmentally required changes to the “Base Building,” as that term is defined below, then Landlord shall, at Tenant’s expense, make such
changes to the Base Building. The “Base Building” shall include the structural portions of the Building, and the public restrooms, elevators, exit stairwells and the systems and equipment located in the internal core of the Building
on the floor or floors on which the Premises are located. In performing the work of any such Alterations, Tenant shall have the work performed in such manner so as not to obstruct access to the Project or any portion thereof, by any other tenant of
the Project, and so as not to 

  

					
		 	-30-	 	 KILROY REALTY

301 BRANNAN STREET
 [StumbleUpon,

obstruct the business of Landlord or other tenants in the Project. Tenant shall retain any union trades to the extent designated by Landlord. Further, Tenant shall not use (and upon notice from
Landlord shall cease using) contractors, services, workmen, labor, materials or equipment that, in Landlord’s reasonable judgment, would disturb labor harmony with the workforce or trades engaged in performing other work, labor or services in
or about the Building or the Common Areas. In addition to Tenant’s obligations under Article 9 of this Lease, upon completion of any Alterations, Tenant agrees to cause a Notice of Completion to be recorded in the office of the Recorder
of the County of San Francisco in accordance with Section 3093 of the Civil Code of the State of California or any successor statute, and as a condition precedent to the enforceability and validity of Landlord’s consent, Tenant shall
deliver to the management office for the Project a reproducible copy of the “as built” and CAD drawings of the Alterations, to the extent applicable, as well as all permits, approvals and other documents issued by any governmental agency
in connection with the Alterations. 
 8.3 Payment for Improvements. If payment is made directly to contractors, Tenant shall
(i) comply with Landlord’s requirements for final lien releases and waivers in connection with Tenant’s payment for work to contractors, and (ii) sign Landlord’s standard contractor’s rules and regulations. If Tenant
orders any work directly from Landlord, Tenant shall pay to Landlord an amount equal to four percent (4%) of the cost of such work to compensate Landlord for all overhead, general conditions, fees and other costs and expenses arising from
Landlord’s involvement with such work. If Tenant does not order any work directly from Landlord, Tenant shall reimburse Landlord for Landlord’s reasonable, actual, out-of-pocket costs and expenses actually incurred in connection with
Landlord’s review of such work. 
 8.4 Construction Insurance. In addition to the requirements of Article 10 of
this Lease, in the event that Tenant makes any Alterations, prior to the commencement of such Alterations, Tenant shall provide Landlord with evidence that Tenant carries “Builder’s All Risk” insurance in an amount reasonably approved
by Landlord covering the construction of such Alterations, and such other insurance as Landlord may reasonably require, it being understood and agreed that all of such Alterations shall be insured by Tenant pursuant to Article 10 of this
Lease immediately upon completion thereof. In addition, Landlord may, in its reasonable discretion, require Tenant to obtain a lien and completion bond or some alternate form of security satisfactory to Landlord in an amount sufficient to ensure the
lien-free completion of any such Alterations costing in excess of One Hundred Thousand Dollars ($100,000) and naming Landlord as a co-obligee. 

8.5 Landlord’s Property. Landlord and Tenant hereby acknowledge and agree that (a) all Alterations, and/or permanently
affixed fixtures, equipment and/or appurtenances (including furniture and equipment permanently attached to the walls, ceiling or slab, but otherwise excluding trade fixtures, moveable equipment and other personal property of Tenant) which may be
installed or placed in or about the Premises, from time to time, shall be at the sole cost of Tenant and shall be and become part of the Premises and the property of Landlord, and (b) the Improvements to be constructed in the Premises pursuant
to the TCCs of the Work Letter shall, upon completion of the same, be and become a part of the Premises and the property of Landlord. Furthermore, Landlord may, by written notice to Tenant prior to the end of the Lease Term, or given following any
earlier termination of this Lease (but subject to the provisions of this Section 8.5), require Tenant, at Tenant’s expense, to (i) remove any Alterations or

 [StumbleUpon,

improvements in the Premises (including, without limitation, any of the “Improvements,” as that term is defined in the Work Letter), and (ii) repair any damage to the Premises and
Building caused by such removal and return the affected portion of the Premises to a building standard improved condition as determined by Landlord; provided, however, if, in connection with its notice to Landlord with respect to any such
Alterations or Cosmetic Alterations, (x) Tenant requests Landlord’s decision with regard to the removal of such Alterations or Cosmetic Alterations, and (y) Landlord thereafter agrees in writing to waive the removal requirement with
regard to such Alterations or Cosmetic Alterations, then Tenant shall not be required to so remove such Alterations or Cosmetic Alterations; provided further, however, that if Tenant requests such a determination from Landlord and Landlord, within
ten (10) business days following Landlord’s receipt of such request from Tenant with respect to Alterations or Cosmetic Alterations, fails to address the removal requirement with regard to such Alterations or Cosmetic Alterations, Landlord
shall be deemed to have agreed to waive the removal requirement with regard to such Alterations or Cosmetic Alterations. In addition, without any requirement of written notice from Landlord, but subject to the provisions of this
Section 8.5, prior to the expiration or earlier termination of this Lease, Tenant, at Tenant’s expense, shall remove those improvements existing in the Premises as of the Date of this Lease and described in Exhibit F
attached hereto and made a part hereof (the “Required Removables”) and shall repair any damage to the Premises and Building caused by such removal and return the affected portions of the Premises to a building standard improved
condition as determined by Landlord (such removal, repair and restoration being referred to herein as the “Required Removable Work”). Notwithstanding the foregoing, if Tenant reasonably estimates that Tenant’s out-of-pocket
costs to perform the Required Removable Work (Tenant’s reasonable estimate of such out-of-pocket costs being referred to herein as the “Required Removable Cost Estimate”) would exceed Twenty-Two Thousand and No/100 Dollars
($22,000.00) in the aggregate (the “Required Removable Cost Cap”), then, at any time prior to the expiration or earlier termination of this Lease, Tenant may deliver written notice to Landlord (the “Required Removable Excess
Cost Notice”) setting forth Tenant’s Required Removable Cost Estimate (together with reasonable supporting documentation therefor) and requesting that Landlord advise Tenant of Landlord’s election with respect to removal of the
Required Removables. Landlord, within ten (10) business days following Landlord’s receipt of the Required Removable Excess Cost Notice, shall deliver a written notice to Tenant (the “Required Removable Election Notice”)
advising Tenant (which election may be made in Landlord’s sole discretion) either: (A) to proceed with the performance of the Required Removable Work, in which event Landlord, within thirty (30) days after receipt of an invoice
(together with reasonable supporting documentation therefor), shall pay to Tenant an amount equal to the difference between (I) Tenant’s total actual out-of-pocket costs incurred in connection with the Required Removable Work (but in no
event in excess of the Required Removable Cost Estimate) less (II) the Required Removable Cost Cap; or (B) to pay to Landlord, prior to the expiration or earlier termination of this Lease, as Additional Rent hereunder, cash in the amount of the
Required Removable Cost Cap, in which event Tenant shall have no further obligation to perform the Required Removable Work and the Required Removables shall be deemed to be and to have become part of the Premises and the property of Landlord.
Landlord’s failure to timely deliver to Tenant the Required Removable Election Notice shall be deemed to constitute Landlord’s election of item (A) in the immediately preceding sentence, and Tenant shall proceed with the performance
of the Required Removable Work accordingly. If Tenant fails to deliver the Required Removable Excess Cost Notice (or if 

  

					
		 	-32-	 	 KILROY REALTY

301 BRANNAN STREET
 [StumbleUpon,

Tenant delivers the Required Removable Excess Cost Notice such that Landlord’s timely delivery of the Required Removable Election Notice cannot be made prior to the expiration or earlier
termination of this Lease), then Tenant shall be required to perform the Required Removable Work prior to the expiration or earlier termination of this Lease without contribution from Landlord. Notwithstanding any provision to the contrary contained
herein, Tenant shall not be required to remove (X) any improvements (other than the Required Removables) existing in the Premises as of the Date of this Lease, or (Y) any Alterations, improvements (including the Improvements)
or Cosmetic Alterations which are normal and customary business office improvements (provided that, in no event shall the Required Removables be considered normal and customary business office improvements). If Tenant fails to complete any such
removal and/or to repair any damage caused by the removal of any Alterations or improvements (including the Required Removables) in the Premises, and to return the affected portion of the Premises to a building standard improved condition as
determined by Landlord, then Landlord may do so and may charge the cost thereof to Tenant; provided that, if Landlord has elected item (A) above with respect to the Required Removables, then Landlord shall deduct from the cost thereof (only
with respect to the Required Removables) the amount that Landlord otherwise would have been required to reimburse Tenant pursuant to said item (A); and further provided that the provisions of this sentence shall not apply with respect to the
Required Removables if Landlord has elected item (B) above (although Tenant shall remain obligated to pay to Landlord cash in the amount of the Required Removable Cost Cap). Tenant hereby protects, defends, indemnifies and holds Landlord
harmless from any liability, cost, obligation, expense or claim of lien in any manner relating to the installation, placement, removal or financing of any such Alterations, improvements, fixtures and/or equipment in, on or about the Premises, which
obligations of Tenant shall survive the expiration or earlier termination of this Lease. 
 ARTICLE 9 

COVENANT AGAINST LIENS 
 Tenant
shall keep the Project and Premises free from any liens or encumbrances arising out of the work performed, materials furnished or obligations incurred by or on behalf of Tenant, (provided that, with respect to the Improvements, Landlord shall be
obligated to pay the Improvement Allowance) and shall protect, defend, indemnify and hold Landlord harmless from and against any claims, liabilities, judgments or costs (including, without limitation, reasonable attorneys’ fees and costs)
arising out of same or in connection therewith. Tenant shall give Landlord notice at least twenty (20) days prior to the commencement of any such work on the Premises (or such additional time as may be necessary under applicable laws) to afford
Landlord the opportunity of posting and recording appropriate notices of non-responsibility. Tenant shall remove any such lien or encumbrance arising out of the Improvements performed in accordance with the TCCs of the Work Letter (whether such
Improvements are performed in the Initial Premises or the Must-Take Space), by bond or otherwise, within ten (10) business days after recordation of such lien or encumbrance (without the requirement of any notice by Landlord); and if Tenant
shall fail to do so, Landlord may pay the amount necessary to remove such lien or encumbrance, without being responsible for investigating the validity thereof; in which case Landlord shall have the right (in its sole discretion) either (a) to
draw down on the “L-C” (as that term is defined in Section 21.1, below) up to the face amount of the L-C, to reimburse Landlord for any amount so paid, or (b) to demand reimbursement from Tenant of any amount so paid

(which shall be deemed Additional Rent under this Lease), in which case Tenant shall reimburse Landlord within ten (10) days after Tenant’s receipt of an invoice from Landlord therefor.
Tenant shall remove any such lien or encumbrance arising out of any Alterations, repairs or any other work performed by or for Tenant (other than the Improvements), by bond or otherwise, within ten (10) business days after notice by Landlord;
and if Tenant shall fail to do so, Landlord may pay the amount necessary to remove such lien or encumbrance, without being responsible for investigating the validity thereof, in which case the amount so paid shall be deemed Additional Rent under
this Lease payable upon demand. Landlord’s rights under this Article 9 shall be without limitation as to other remedies available to Landlord under this Lease. Nothing contained in this Lease shall authorize Tenant to do any act which
shall subject Landlord’s title to the Building or Premises to any liens or encumbrances whether claimed by operation of law or express or implied contract. Any claim to a lien or encumbrance upon the Building or Premises arising in connection
with any such work or respecting the Premises not performed by or at the request of Landlord shall be null and void, or at Landlord’s option shall attach only against Tenant’s interest in the Premises and shall in all respects be
subordinate to Landlord’s title to the Project, Building and Premises. 
 ARTICLE 10 

INSURANCE 
 10.1
Indemnification and Waiver. Tenant hereby assumes all risk of damage to property or injury to persons in, upon or about the Premises from any cause whatsoever and agrees that Landlord, its partners, subpartners and their respective
officers, agents, servants, employees, and independent contractors (collectively, “Landlord Parties”) shall not be liable for, and are hereby released from any responsibility for, any damage either to person or property or resulting
from the loss of use thereof, which damage is sustained by Tenant or by other persons claiming through Tenant. Tenant shall indemnify, defend, protect, and hold harmless the Landlord Parties from any and all loss, cost, damage, expense and liability
(including without limitation court costs and reasonable attorneys’ fees) incurred in connection with or arising from: (a) any causes in, on or about the Premises; (b) the use or occupancy of the Premises by Tenant or any person
claiming under Tenant; (c) any activity, work, or thing done, or permitted or suffered by Tenant in or about the Premises; (d) any acts, omission, or negligence of Tenant or any person claiming under Tenant, or the contractors, agents,
employees, invitees, or visitors of Tenant or any such person (collectively, “Tenant Parties”); (e) any breach, violation, or nonperformance by Tenant or any person claiming under Tenant or the employees, agents, contractors,
invitees, or visitors of Tenant or any such person of any term, covenant, or provision of this Lease or any law, ordinance, or governmental requirement of any kind; (f) any injury or damage to the person, property, or business of Tenant, its
employees, agents, contractors, invitees, visitors, or any other person entering upon the Premises under the express or implied invitation of Tenant; or (g) the placement of any personal property or other items within the Premises, provided
that the foregoing indemnity shall not apply to the extent of the negligence or willful misconduct of Landlord or the Landlord Parties. Should Landlord be named as a defendant in any suit brought against Tenant in connection with or arising out of
Tenant’s occupancy of the Premises, Tenant shall pay to Landlord its costs and expenses incurred in such suit, including without limitation, its actual professional fees such as appraisers’, accountants’ and attorneys’ fees.
Further, Tenant’s agreement to indemnify Landlord pursuant to this

Section 10.1 is not intended and shall not relieve any insurance carrier of its obligations under policies required to be carried by Tenant pursuant to the provisions of this Lease,
to the extent such policies cover the matters subject to Tenant’s indemnification obligations; nor shall they supersede any inconsistent agreement of the parties set forth in any other provision of this Lease. The provisions of this
Section 10.1 shall survive the expiration or sooner termination of this Lease with respect to any claims or liability arising in connection with any event occurring prior to such expiration or termination. 

10.2 Tenant’s Compliance With Landlord’s Fire and Casualty Insurance. Tenant shall, at Tenant’s expense, comply
with Landlord’s insurance company requirements pertaining to the use of the Premises. If Tenant’s conduct or use of the Premises causes any increase in the premium for such insurance policies then Tenant shall reimburse Landlord for any
such increase. Tenant, at Tenant’s expense, shall comply with all rules, orders, regulations or requirements of the American Insurance Association (formerly the National Board of Fire Underwriters) and with any similar body. 

10.3 Tenant’s Insurance. Throughout the Lease Term, Tenant shall maintain the following coverages in the following amounts.
The required evidence of coverage must be delivered to Landlord on or before the date required under Section 10.4(1) sub-sections (x) and (y), or Section 10.4(11) below (as applicable). Such policies shall be for
a term of at least one (1) year, or the length of the remaining term of this Lease, whichever is less. 
 10.3.1 Commercial General
Liability Insurance, including Broad Form contractual liability covering the insured against claims of bodily injury, personal injury and property damage (including loss of use thereof) based upon or arising out of Tenant’s operations,
occupancy or maintenance of the Premises and all areas appurtenant thereto. Such insurance shall be written on an “occurrence” basis. Landlord and any other party the Landlord so specifies that has a material financial interest in the
Project, including Landlord’s managing agent, ground lessor and/or lender, if any, shall be named as additional insureds as their interests may appear using Insurance Service Organization’s formCG2011 or a comparable form approved by
Landlord. Tenant shall provide an endorsement or policy excerpt showing that Tenant’s coverage is primary and any insurance carried by Landlord shall be excess and non-contributing. The coverage shall also be extended to include damage caused
by heat, smoke or fumes from a hostile fire. The policy shall not contain any intra-insured exclusions as between insured persons or organizations. This policy shall include coverage for all liabilities assumed under this Lease as an insured
contract for the performance of all of Tenant’s indemnity obligations under this Lease. The limits of said insurance shall not, however, limit the liability of Tenant nor relieve Tenant of any obligation hereunder. Limits of liability insurance
shall not be less than the following; provided, however, such limits may be achieved through the use of an Umbrella/Excess Policy: 
  

			
	Bodily Injury and Property Damage Liability	  	$5,000,000 each occurrence
		
	Personal Injury and Advertising Liability	  	$5,000,000 each occurrence
		
	Tenant Legal Liability/Damage to Rented Premises Liability	  	$1,000,000.00

 10.3.2 Property Insurance covering (i) all office furniture, personal property, business and
trade fixtures, office equipment, free-standing cabinet work, movable partitions, merchandise and all other items of Tenant’s business personal property on the Premises installed by, for, or at the expense of Tenant, (ii) the
“Improvements,” as that term is defined in Section 2.1 of the Work Letter, and (iii) all Alterations performed in the Premises. Such insurance shall be written on a Special Form basis, for the full replacement cost value
(subject to reasonable deductible amounts), without deduction for depreciation of the covered items and in amounts that meet any co-insurance clauses of the policies of insurance and shall include coverage for (a) all perils included in the CP
10 30 04 02 Coverage Special Form, and (b) water damage from any cause whatsoever, including, but not limited to, backup or overflow from sprinkler leakage, bursting, leaking or stoppage of any pipes, explosion, and backup or overflow from
sewers or drains. 
 10.3.2.1 Adjacent Premises. Tenant shall pay for any increase in the premiums for the
property insurance of the Project if said increase is caused by Tenant’s acts, omissions, use or occupancy of the Premises. 

10.3.2.2 Property Damage. Tenant shall use the proceeds from any such insurance for the replacement of personal
property, trade fixtures and Alterations. 
 10.3.2.3 No representation of Adequate Coverage. Landlord makes no
representation that the limits or forms of coverage of insurance specified herein are adequate to cover Tenant’s property, business operations or obligations under this Lease. 

10.3.3 Property Insurance Subrogation. Landlord and Tenant intend that their respective property loss risks shall be borne by
insurance carriers to the extent above provided (and, in the case of Tenant, by an insurance carrier satisfying the requirements of Section 10.4(i) below), and Landlord and Tenant hereby agree to look solely to, and seek recovery only
from, their respective insurance carriers in the event of a property loss to the extent that such coverage is agreed to be provided hereunder. The parties each hereby waive all rights and claims against each other for such losses, and waive all
rights of subrogation of their respective insurers. Landlord and Tenant hereby represent and warrant that their respective “all risk” property insurance policies include a waiver of (i) subrogation by the insurers, and (ii) all
rights based upon an assignment from its insured, against Landlord and/or any of the Landlord Parties or Tenant and/or any of the Tenant Parties (as the case may be) in connection with any property loss risk thereby insured against. Tenant will
cause all other occupants of the Premises claiming by, under, or through Tenant to execute and deliver to Landlord a waiver of claims similar to the waiver in this Section 10.3.3 and to obtain such waiver of subrogation rights
endorsements. If either party hereto fails to maintain the waivers set forth in items (i) and (ii) above, the party not maintaining the requisite waivers shall indemnify, defend, protect, and hold harmless the other party for, from and
against any and all claims, losses, costs, damages, expenses and liabilities (including, without limitation, court costs and reasonable attorneys’ fees) arising out of, resulting from, or relating to, such failure.

Employer’s Liability with minimum limits of not less than $1,000,000 each accident/employee/disease. 
 10.4 Form of

Tenant shall fail to procure such insurance, or to deliver such policies or certificates and applicable endorsements, Landlord may, at its option, after written notice to Tenant and Tenant’s failure to obtain such insurance within five
(5) days thereafter, procure such policies for the account of Tenant and the sole benefit of Landlord, and the cost thereof shall be paid to Landlord after delivery to Tenant of bills therefor. 

10.5 Additional Insurance Obligations. Tenant shall carry and maintain during the entire Lease Term, at Tenant’s sole cost
and expense, increased amounts of the insurance required to be carried by Tenant pursuant to this Article 10 and such other reasonable types of insurance coverage and in such reasonable amounts covering the Premises and Tenant’s
operations therein, as may be reasonably requested by Landlord. Notwithstanding the foregoing, Landlord’s request shall only be considered reasonable if such increased coverage amounts and/or such new types of insurance are consistent with the
requirements of a majority of Comparable Buildings.

Landlord, Third Party Contractor’s certificates of insurance and applicable endorsements at least seven (7) business days prior to the commencement of work in or about the Premises by any vendor or any other third-party contractor

Section 10.6, (b) provide a waiver of subrogation in favor of Landlord under such Third Party Contractor’s commercial general liability insurance, (c) be primary and any insurance carried by Landlord shall be excess and

10.7.2 Landlord shall insure the Building and Landlord’s remaining interest in the Improvements and Alterations with a policy of Physical
Damage Insurance including building ordinance coverage, written on a standard Causes of Loss - Special Form basis (against loss or damage due to fire and other casualties covered within the classification of fire and extended coverage, vandalism,
and malicious mischief, sprinkler leakage, water damage and special extended coverage), covering the full replacement cost of the Base Building, Premises and other improvements (including coverages for enforcement of Applicable Laws requiring the
upgrading, demolition, reconstruction and/or replacement of any portion of the Building as a result of a covered loss) without a deduction for depreciation. 

10.7.3 Landlord shall maintain Boiler and Machinery/Equipment Breakdown Insurance covering the Building against risks commonly insured against
by a Boiler and Machinery/Equipment Breakdown policy and such policy shall cover the full replacement costs, without deduction for depreciation. 

10.7.4 The foregoing coverages shall contain commercially reasonable deductible amounts from such companies, and on such other terms and
conditions, as Landlord may from time to time reasonably determine. 
 10.7.5 Additionally, at the option of Landlord, such insurance
coverage may include the risk of (i) earthquake, (ii) flood damage and additional hazards, or (iii) a rental loss endorsement for a period of up to two (2) years. 

10.7.6 Notwithstanding the foregoing provisions of this Section 10.7, the coverage and amounts of insurance carried by Landlord in
connection with the Building shall, at a minimum, be comparable to the coverage and amounts of insurance which are carried by reasonably prudent landlords of Comparable Buildings. In addition, Landlord shall carry Worker’s Compensation and
Employer’s Liability coverage as required by applicable law. 
 ARTICLE 11 

DAMAGE AND DESTRUCTION 

11.1 Repair of Damage to Premises by Landlord. Tenant shall promptly notify Landlord of any damage to the Premises resulting
from fire or any other casualty. If the Premises or any Common Areas serving or providing access to the Premises shall be damaged by fire or other casualty, Landlord shall promptly and diligently, subject to reasonable delays for insurance
adjustment or other matters beyond Landlord’s reasonable control, and subject to all other terms of this Article 11, restore the Base Building and such Common Areas. Such restoration shall be to substantially the same condition of the
Base Building and the Common Areas prior to the casualty, except for modifications required by zoning and building codes and other laws or by

the holder of a mortgage on the Building or Project or any other modifications to the Common Areas deemed desirable by Landlord, which are consistent with the character of the Project, provided
that access to the Premises and any common restrooms serving the Premises shall not be materially impaired. Notwithstanding any other provision of this Lease, upon the occurrence of any damage to the Premises, upon notice (the “Landlord
Repair Notice”) to Tenant from Landlord, Tenant shall assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under Tenant’s insurance required to be carried under items (ii) and
(iii) of Section 10.3.2 of this Lease with respect to the Improvements and any Alterations, and Landlord shall repair any injury or damage to the Improvements and such Alterations installed in the Premises and shall return such
Improvements and such Alterations to their original condition; provided that if the cost of repair to the Improvements and such Alterations by Landlord exceeds the amount of insurance proceeds received by Landlord from Tenant’s insurance
carrier, as assigned by Tenant, the cost of such repairs shall be paid by Tenant to Landlord prior to Landlord’s commencement of repair of the damage. In the event that Landlord does not deliver the Landlord Repair Notice within sixty
(60) days following the date the casualty becomes known to Landlord, Tenant shall, at its sole cost and expense, repair any injury or damage to the Improvements installed in the Premises and shall return such Improvements to their original
condition. Whether or not Landlord delivers a Landlord Repair Notice, prior to the commencement of construction, Tenant shall submit to Landlord, for Landlord’s review and approval, all plans, specifications and working drawings relating
thereto, and Landlord shall select the contractors to perform such improvement work. Landlord shall not be liable for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant’s business resulting in any way from such damage
or the repair thereof; provided however, that if such fire or other casualty shall have damaged the Premises or Common Areas necessary to Tenant’s occupancy, and if such damage is not the result of the willful misconduct of Tenant or
Tenant’s employees, contractors, licensees, or invitees, Landlord shall allow Tenant a proportionate abatement of Rent during the time and to the extent the Premises are unfit for occupancy, which proportionality shall be based on the ratio
that the amount of rentable square feet of the Premises which is unfit for occupancy for the purposes permitted under this Lease and not occupied by Tenant as a result thereof bears to the total rentable square feet of the Premises. In the event
that Landlord shall not deliver the Landlord Repair Notice, Tenant’s right to rent abatement pursuant to the preceding sentence shall terminate as of the date which is reasonably determined by Landlord to be the date Tenant should have
completed repairs to the Premises assuming Tenant used reasonable due diligence in connection therewith. 
 11.2 Landlord’s
Option to Repair. Notwithstanding the terms of Section 11.1 of this Lease, Landlord may elect not to rebuild and/or restore the Premises, Building and/or Project, and instead terminate this Lease, by notifying Tenant in writing
of such termination within sixty (60) days after the date of discovery of the damage, such notice to include a termination date giving Tenant sixty (60) days to vacate the Premises, but Landlord may so elect only if the Building or Project
shall be damaged by fire or other casualty or cause, whether or not the Premises are affected, and one or more of the following conditions is present: (i) in Landlord’s reasonable judgment, repairs cannot reasonably be completed within one
hundred eighty (180) days after the date of discovery of the damage (when such repairs are made without the payment of overtime or other premiums); (ii) the holder of any mortgage on the Building or Project shall require that the insurance
proceeds or any portion thereof be used to retire the mortgage debt; (iii) the damage is not fully covered by Landlord’s insurance policies; (iv) the 

  

					
		 	-39-	 	 KILROY REALTY

 [StumbleUpon,

damage occurs during the last twelve (12) months of the Lease Term; or (v) any owner of any other portion of the Project, other than Landlord, does not intend to repair the damage to
such portion of the Project; provided, however, that if Landlord does not elect to terminate this Lease pursuant to Landlord’s termination right as provided above, and the repairs cannot, in the reasonable opinion of Landlord, be completed
within one hundred eighty (180) days after being commenced, then Landlord shall deliver to Tenant a written notice (the “Target Restoration Notice”) within sixty (60) days after the date of discovery of the damage setting
forth the date on which Landlord estimates such repairs will be completed (the “Target Restoration Date”), and Tenant may elect, no earlier than sixty (60) days after the date of the damage and not later than ninety
(90) days after the date of such damage, to terminate this Lease by written notice to Landlord effective as of the date specified in the notice, which date shall not be less than thirty (30) days nor more than sixty (60) days after
the date such notice is given by Tenant. Furthermore, if neither Landlord nor Tenant has terminated this Lease, and the repairs are not actually completed within sixty (60) days after the Target Restoration Date (or, if no Target Restoration
Notice was given, then within one hundred eighty (180) days after commencement of such repairs), Tenant shall have the right to terminate this Lease until such time as the repairs are complete, by notice to Landlord (the “Damage
Termination Notice”), effective as of a date set forth in the Damage Termination Notice (the “Damage Termination Date”), which Damage Termination Date shall not be less than ten (10) business days following the
delivery of the Damage Termination Notice. Notwithstanding the foregoing, if Tenant delivers a Damage Termination Notice to Landlord, then Landlord shall have the right to suspend the occurrence of the Damage Termination Date for a period ending
thirty (30) days after the Damage Termination Date set forth in the Damage Termination Notice by delivering to Tenant, within five (5) business days of Landlord’s receipt of the Damage Termination Notice, a certificate of
Landlord’s contractor responsible for the repair of the damage certifying that it is such contractor’s good faith judgment that the repairs shall be substantially completed within thirty (30) days after the Damage Termination Date. If
repairs shall be substantially completed prior to the expiration of such thirty-day period, then the Damage Termination Notice shall be of no force or effect, but if the repairs shall not be substantially completed within such thirty-day period,
then this Lease shall terminate upon the expiration of such thirty-day period. At any time, from time to time, after the date occurring sixty (60) days after the date of the damage, Tenant may request that Landlord inform Tenant of
Landlord’s reasonable opinion of the date of completion of the repairs and Landlord shall respond to such request within five (5) business days, which response shall constitute a Target Restoration Notice. Notwithstanding the provisions of
this Section 11.2, Tenant shall have the right to terminate this Lease under this Section 11.2 only if each of the following conditions is satisfied: (a) the damage to the Project by fire or other casualty was not caused
by the gross negligence or intentional act of Tenant or its partners or subpartners and their respective officers, agents, servants, employees, and independent contractors; (b) as a result of the damage, Tenant cannot reasonably conduct
business from the Premises; and (c) as a result of the damage to the Project, Tenant does not occupy or use the Premises at all. In the event this Lease is terminated in accordance with the terms of this Section 11.2, Tenant shall
assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under Tenant’s insurance required under items (ii) and (iii) of Section 10.3.2 of this Lease. 

11.3 Waiver of Statutory Provisions. The provisions of this Lease, including this Article 11, constitute an express
agreement between Landlord and Tenant with respect to any

301 BRANNAN STREET
 [StumbleUpon,

and all damage to, or destruction of, all or any part of the Premises, the Building or the Project, and any statute or regulation of the State of California, including, without limitation,
Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or obligations concerning damage or destruction in the absence of an express agreement between the parties, and any other statute or regulation, now or hereafter
in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises, the Building or the Project. 

ARTICLE 12 

NONWAIVER 
 No
provision of this Lease shall be deemed waived by either party hereto unless expressly waived in a writing signed thereby. The waiver by either party hereto of any breach of any term, covenant or condition herein contained shall not be deemed to be
a waiver of any subsequent breach of same or any other term, covenant or condition herein contained. The subsequent acceptance of Rent hereunder by Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of any term, covenant
or condition of this Lease, other than the failure of Tenant to pay the particular Rent so accepted, regardless of Landlord’s knowledge of such preceding breach at the time of acceptance of such Rent. No acceptance of a lesser amount than the
Rent herein stipulated shall be deemed a waiver of Landlord’s right to receive the full amount due, nor shall any endorsement or statement on any check or payment or any letter accompanying such check or payment be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the full amount due. No receipt of monies by Landlord from Tenant after the termination of this Lease shall in any way alter the length
of the Lease Term or of Tenant’s right of possession hereunder, or after the giving of any notice shall reinstate, continue or extend the Lease Term or affect any notice given Tenant prior to the receipt of such monies, it being agreed that
after the service of notice or the commencement of a suit, or after final judgment for possession of the Premises, Landlord may receive and collect any Rent due, and the payment of said Rent shall not waive or affect said notice, suit or judgment.

 ARTICLE 13 

CONDEMNATION 
 If
the whole or any material part of the Premises, Building or Project that would materially adversely affect Tenant’s access to and use of the Premises shall be taken by power of eminent domain or condemned by any competent authority for any
public or quasi-public use or purpose, or if any adjacent property or street shall be so taken or condemned, or reconfigured or vacated by such authority in such manner as to require the use, reconstruction or remodeling of any part of the Premises,
Building or Project, or if Landlord shall grant a deed or other instrument in lieu of such taking by eminent domain or condemnation, Landlord shall have the option to terminate this Lease effective as of the date possession is required to be
surrendered to the authority. If more than twenty-five percent (25%) of the rentable square feet of the Premises is taken, or if access to the Premises is substantially impaired, in each case for a period in excess of one hundred eighty
(180) days, Tenant shall have the option to terminate this Lease effective as of the date possession is required to be surrendered to the authority. Tenant shall not because

of such taking assert any claim against Landlord or the authority for any compensation because of such taking and Landlord shall be entitled to the entire award or payment in connection
therewith, except that Tenant shall have the right to file any separate claim available to Tenant for any taking of Tenant’s personal property and fixtures belonging to Tenant and removable by Tenant upon expiration of the Lease Term pursuant
to the terms of this Lease, and for moving expenses, so long as such claims do not diminish the award available to Landlord, its ground lessor with respect to the Building or Project or its mortgagee, and such claim is payable separately to Tenant.
All Rent shall be apportioned as of the date of such termination. If any part of the Premises shall be taken, and this Lease shall not be so terminated, the Rent shall be proportionately abated. Tenant hereby waives any and all rights it might
otherwise have pursuant to Section 1265.130 of The California Code of Civil Procedure. Notwithstanding anything to the contrary contained in this Article 13, in the event of a temporary taking of all or any portion of the Premises for a
period of one hundred and eighty (180) days or less, then this Lease shall not terminate but the Base Rent and the Additional Rent shall be abated for the period of such taking in proportion to the ratio that the amount of rentable square feet
of the Premises taken bears to the total rentable square feet of the Premises. Landlord shall be entitled to receive the entire award made in connection with any such temporary taking. 

ARTICLE 14 

ASSIGNMENT AND SUBLETTING 

14.1 Transfers. Tenant shall not, without the prior written consent of Landlord, assign, mortgage, pledge, hypothecate,
encumber, or permit any lien to attach to, or otherwise transfer, this Lease or any interest hereunder, permit any assignment, or other transfer of this Lease or any interest hereunder by operation of law, sublet the Premises or any part thereof, or
enter into any license or concession agreements or otherwise permit the occupancy or use of the Premises or any part thereof by any persons other than Tenant and its employees and contractors (all of the foregoing are hereinafter sometimes referred
to collectively as “Transfers” and any person to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a “Transferee”). If Tenant desires Landlord’s consent to any Transfer,
Tenant shall notify Landlord in writing, which notice (the “Transfer Notice”) shall include (i) the proposed effective date of the Transfer, which shall not be less than thirty (30) days nor more than one hundred eighty
(180) days after the date of delivery of the Transfer Notice, (ii) a description of the portion of the Premises to be transferred (the “Subject Space”), (iii) all of the terms of the proposed Transfer and the
consideration therefor, including calculation of the “Transfer Premium”, as that term is defined in Section 14.3 below, in connection with such Transfer, the name and address of the proposed Transferee, and a copy of all
existing executed and/or proposed documentation pertaining to the proposed Transfer, including all existing operative documents to be executed to evidence such Transfer or the agreements incidental or related to such Transfer, provided that Landlord
shall have the right to require Tenant to utilize Landlord’s standard consent document in connection with the documentation of such Transfer, (iv) current financial statements of the proposed Transferee certified by an officer, partner or
owner thereof, business credit and personal references and history of the proposed Transferee and any other information required by Landlord which will enable Landlord to determine the financial responsibility, character, and reputation of the
proposed Transferee, nature of such Transferee’s business and proposed use of the Subject Space and (v) an executed estoppel certificate from 

  

					
		 	-42-	 	 KILROY REALTY

 [StumbleUpon,

Tenant in the form attached hereto as Exhibit E. Landlord shall respond to Tenant in writing approving and disapproving of the proposed Transfer within fifteen (15) business
days after receipt of the Transfer Notice. Any Transfer made without Landlord’s prior written consent shall, at Landlord’s option, be null, void and of no effect, and shall, at Landlord’s option, constitute a default by Tenant under
this Lease. Whether or not Landlord consents to any proposed Transfer, Tenant shall pay Landlord’s review and processing fees, as well as any reasonable professional fees (including, without limitation, attorneys’, accountants’,
architects’, engineers’ and consultants’ fees) incurred by Landlord, within thirty (30) days after written request by Landlord; provided that such costs and expenses shall not exceed Two Thousand Five Hundred and 00/100 Dollars
($2,500.00) for a Transfer in the ordinary course of business. Landlord and Tenant hereby agree that a proposed Transfer shall not be considered “in the ordinary course of business” if such particular proposed Transfer involves the review
of documentation by Landlord on more than two (2) occasions. 
 14.2 Landlord’s Consent. Landlord shall not
unreasonably withhold its consent to any proposed Transfer of the Subject Space to the Transferee on the terms specified in the Transfer Notice. Without limitation as to other reasonable grounds for withholding consent, the parties hereby agree that
it shall be reasonable under this Lease and under any applicable law for Landlord to withhold consent to any proposed Transfer where one or more of the following apply: 

14.2.1 The Transferee is of a character or reputation or engaged in a business which is not consistent with the quality of the Building or the
Project, or would be a significantly less prestigious occupant of the Building than Tenant; 
 14.2.2 The Transferee intends to use the
Subject Space for purposes which are not permitted under this Lease; 
 14.2.3 The Transferee is either a governmental agency or
instrumentality thereof; 
 14.2.4 The Transferee is not a party of reasonable financial worth and/or financial stability in light of the
responsibilities to be undertaken in connection with the Transfer on the date consent is requested; 
 14.2.5 The proposed Transfer would
cause a violation of another lease for space in the Project, or would give an occupant of the Project a right to cancel its lease; 
 14.2.6
The terms of the proposed Transfer will allow the Transferee to exercise a right of renewal, right of expansion, right of first offer, or other similar right held by Tenant (or will allow the Transferee to occupy space leased by Tenant pursuant to
any such right); or 
 14.2.7 Either the proposed Transferee, or any person or entity which directly or indirectly, controls, is controlled
by, or is under common control with, the proposed Transferee, (i) occupies space in the Project at the time of the request for consent, or (ii) is negotiating with Landlord to lease space in the Project at such time, or (iii) has
negotiated with Landlord during the six (6)-month period immediately preceding the Transfer Notice; provided that, in any such instance, Landlord has space available in the Project at the time of the request for consent that would reasonably satisfy
such proposed Transferee’s needs; or 

  

					
		 	-43-	 	 KILROY REALTY

301 BRANNAN STREET
 [StumbleUpon,
Inc.]

 14.2.8 The Transferee does not intend to occupy all or substantially all of the Subject Space and
conduct its business therefrom for a substantial portion of the term of the Transfer. 
 If Landlord consents to any Transfer pursuant to
the terms of this Section 14.2 (and does not exercise any recapture rights Landlord may have under Section 14.4 of this Lease), Tenant may within six (6) months after Landlord’s consent, but not later than the
expiration of said six-month period, enter into such Transfer of the Premises or portion thereof, upon substantially the same terms and conditions as are set forth in the Transfer Notice furnished by Tenant to Landlord pursuant to
Section 14.1 of this Lease, provided that if there are any changes in the terms and conditions from those specified in the Transfer Notice (i) such that Landlord would initially have been entitled to refuse its consent to such
Transfer under this Section 14.2, or (ii) which would cause the proposed Transfer to be more favorable to the Transferee than the terms set forth in Tenant’s original Transfer Notice, Tenant shall again submit the Transfer to
Landlord for its approval and other action under this Article 14 (including Landlord’s right of recapture, if any, under Section 14.4 of this Lease). Notwithstanding anything to the contrary in this Lease, if Tenant or any
proposed Transferee claims that Landlord has unreasonably withheld or delayed its consent under Section 14.2 or otherwise has breached or acted unreasonably under this Article 14, then Tenant’s sole and exclusive remedy shall
be to have the dispute resolved by arbitration seeking a decree of specific performance compelling Landlord to consent. The arbitration shall be by the office of the Judicial Arbitration & Mediation Services, Inc. closest to the Project and
conducted pursuant to its Streamlined Arbitration Rules and Procedures. The arbitrator’s powers shall be limited to granting or denying specific performance compelling Landlord to consent, or declaring the rights of the parties with respect to
such consent. In addition, if this Lease otherwise provides for attorneys’ fees, the arbitrator may award attorneys’ fees and the fees and costs of the arbitration to the prevailing party. 

14.3 Transfer Premium. If Landlord consents to a Transfer, as a condition thereto which the parties hereby agree is reasonable,
Tenant shall pay to Landlord fifty percent (50%) of any “Transfer Premium,” as that term is defined in this Section 14.3, received by Tenant from such Transferee. “Transfer Premium” shall mean all rent,
additional rent or other consideration payable by such Transferee in connection with the Transfer in excess of the Rent and Additional Rent payable by Tenant under this Lease during the term of the Transfer on a per rentable square foot basis if
less than all of the Premises is transferred, after deducting the reasonable expenses incurred by Tenant for (i) any changes, alterations and improvements to the Premises in connection with the Transfer, (ii) any free base rent or other
economic concessions reasonably provided to the Transferee, and (iii) any reasonable legal fees and brokerage commissions in connection with the Transfer. “Transfer Premium” shall also include, but not be limited to, key money, bonus
money or other cash consideration paid by Transferee to Tenant in connection with such Transfer, and any payment in excess of fair market value for services rendered by Tenant to Transferee or for assets, fixtures, inventory, equipment, or furniture
transferred by Tenant to Transferee in connection with such Transfer. For purposes of calculating any such effective rent all such concessions shall be amortized on a straight-line basis over the relevant term. 

14.4 Landlord’s Option as to Subject Space. Notwithstanding anything to the contrary contained in this Article 14,
in the event that Tenant contemplates a Transfer 

  

					
		 	-44-	 	 KILROY REALTY

301 BRANNAN STREET
 [StumbleUpon,
Inc.]

 
(“Contemplated Transfer”), at any time after Tenant has received a bona fide offer from any proposed Transferee that Tenant is prepared to accept regarding the terms of an
assignment or sublease concerning the “Contemplated Transfer Space” (as that term is defined below), but in any event prior to consummating any such Transfer, Tenant shall submit to Landlord a written notice setting forth the name and
contact information of the proposed Transferee and all of the terms of the proposed Transfer and the consideration therefor, together with any letter of intent or other signed writing between Tenant and such proposed Transferee regarding the
proposed Transfer, if any (such written notice, together with any such letter of intent or other signed writing being referred to herein as an “Intention to Transfer Notice”). The Intention to Transfer Notice shall, at a minimum,
specify the portion of and amount of rentable square feet of the Premises which Tenant intends to Transfer (the “Contemplated Transfer Space”), the contemplated date of commencement of the Contemplated Transfer (the
“Contemplated Effective Date”), and the contemplated length of the term of such Contemplated Transfer, and shall specify that such Intention to Transfer Notice is delivered to Landlord pursuant to this Section 14.4 in
order to allow Landlord to elect to recapture the Contemplated Transfer Space for the remainder of the Lease Term; provided, however, that Landlord hereby acknowledges and agrees that Tenant shall have no obligation to deliver an Intention to
Transfer Notice hereunder, and Landlord shall have no right to recapture space with respect to a sublease of less than seventy percent (70%) of the Premises for less than fifty percent (50%) of the remainder of the Lease Term. Thereafter,
Landlord shall have the option, by giving written notice to Tenant within fifteen (15) business days after receipt of any Intention to Transfer Notice, to recapture the Contemplated Transfer Space. Any recapture under this
Section 14.4 shall cancel and terminate this Lease with respect to Contemplated Transfer Space as of the Contemplated Effective Date. In the event of a recapture by Landlord, (i) Landlord shall install, on a commercially reasonable
basis, any corridor and/or demising wall which is required as a result of a recapture by Landlord pursuant to the terms hereof, (ii) the Rent reserved herein shall be prorated on the basis of the number of rentable square feet retained by
Tenant in proportion to the number of rentable square feet contained in the Premises, and (iii) this Lease as so amended shall continue thereafter in full force and effect, and upon request of either party, the parties shall execute written
confirmation of the same. If Landlord declines, or fails to elect in a timely manner to recapture the Contemplated Transfer Space under this Section 14.4 in response to an Intention to Transfer Notice, then, provided Landlord consents to
the proposed Transfer, and provided that the proposed Transfer is with the proposed Transferee named in the Intention to Transfer Notice and is substantially on the terms set forth in the Intention to Transfer Notice, Tenant shall be entitled to
proceed to transfer the Contemplated Transfer Space to the proposed Transferee, subject to provisions of this Article 14, within the period of six (6) months following the date of the Intention to Transfer Notice (“Six Month
Period”). If (a) the proposed Transfer is modified such that the terms of the modified proposed Transfer are more than ten percent (10%) more favorable to Tenant than the terms set forth in the Intention to Transfer Notice
delivered to Landlord, or (b) the proposed Transfer is not consummated within the Six Month Period (or if the Transfer is so consummated, then upon the expiration of the term of the Transfer of such Transfer Space consummated within such Six
Month Period), Tenant shall again be required to submit a new Intention to Transfer Notice to Landlord with respect any contemplated Transfer, as provided above in this Section 14.4. 

14.5 Effect of Transfer. If Landlord consents to a Transfer, (i) the TCCs of this Lease shall in no way be deemed to have
been waived or modified, (ii) such consent shall not be 

  

					
		 	-45-	 	 KILROY REALTY

301 BRANNAN STREET
 [StumbleUpon,

deemed consent to any further Transfer by either Tenant or a Transferee, (iii) Tenant shall deliver to Landlord, promptly after execution, an original executed copy of all documentation
pertaining to the Transfer in form reasonably acceptable to Landlord, (iv) Tenant shall furnish upon Landlord’s request a complete statement, certified by Tenant, setting forth in detail the computation of any Transfer Premium Tenant has
derived and shall derive from such Transfer, and (v) no Transfer relating to this Lease or agreement entered into with respect thereto, whether with or without Landlord’s consent, shall relieve Tenant or any guarantor of the Lease from any
liability under this Lease, including, without limitation, in connection with the Subject Space. Landlord or its authorized representatives shall have the right at all reasonable times to audit the books, records and papers of Tenant relating to any
Transfer, and shall have the right to make copies thereof. If the Transfer Premium respecting any Transfer shall be found understated, Tenant shall, within thirty (30) days after demand, pay the deficiency, and if understated by more than two
percent (2%), Tenant shall pay Landlord’s costs of such audit. 
 14.6 Additional Transfers. For purposes of this Lease,
subject to the terms of Section 14.8 below, the term “Transfer” shall also include (i) if Tenant is a partnership, the withdrawal or change, voluntary, involuntary or by operation of law, of more than fifty percent
(50%) or more of the partners, or transfer of more than fifty percent (50%) or more of partnership interests, within a twelve (12)-month period, or the dissolution of the partnership without immediate reconstitution thereof, and
(ii) if Tenant is a closely held corporation (i.e., whose stock is not publicly held and not traded through an exchange or over the counter), (A) the dissolution, merger, consolidation or other reorganization of Tenant or
(B) the sale or other transfer of an aggregate of more than fifty percent (50%) or more of the voting shares of Tenant (other than to immediate family members by reason of gift or death), within a twelve (12)-month period, or (C) the
sale, mortgage, hypothecation or pledge of an aggregate of more than fifty percent (50%) or more of the value of the unencumbered assets of Tenant within a twelve (12)-month period. A Transfer pursuant to
either clause (i) or (ii) above shall hereinafter be referred to as an “Additional Transfer.” 
 14.7
Occurrence of Default. Any Transfer hereunder shall be subordinate and subject to the provisions of this Lease, and if this Lease shall be terminated during the term of any Transfer, Landlord shall have the right to: (i) treat
such Transfer as cancelled and repossess the Subject Space by any lawful means, or (ii) require that such Transferee attorn to and recognize Landlord as its landlord under any such Transfer. If Tenant shall be in default under this Lease,
Landlord is hereby irrevocably authorized, as Tenant’s agent and attorney-in-fact, to direct any Transferee to make all payments under or in connection with the Transfer directly to Landlord (which Landlord shall apply towards Tenant’s
obligations under this Lease) until such default is cured. Such Transferee shall rely on any representation by Landlord that Tenant is in default hereunder, without any need for confirmation thereof by Tenant. Upon any assignment, the assignee shall
assume in writing all obligations and covenants of Tenant thereafter to be performed or observed under this Lease. No collection or acceptance of rent by Landlord from any Transferee shall be deemed a waiver of any provision of this Article
14 or the approval of any Transferee or a release of Tenant from any obligation under this Lease, whether theretofore or thereafter accruing. In no event shall Landlord’s enforcement of any provision of this Lease against any Transferee be
deemed a waiver of Landlord’s right to enforce any term of this Lease against Tenant or any other person. If Tenant’s obligations hereunder have been guaranteed, Landlord’s consent to any Transfer shall not be effective unless the
guarantor also consents to such Transfer.

 14.8 Deemed Consent Transfers. Notwithstanding anything to the contrary contained
in this Lease, (A) an assignment or subletting of all or a portion of the Premises to an affiliate of Tenant (an entity which is controlled by, controls, or is under common control with, Tenant as of the date of this Lease), (B) a sale of
corporate shares of capital stock in Tenant on a nationally-recognized stock exchange, (C) an assignment of the Lease to an entity which acquires all or substantially all of the stock or assets of Tenant, (D) an assignment of the Lease to
an entity which is the resulting entity of a merger or consolidation of Tenant during the Lease Term, or (E) an Additional Transfer, shall not be deemed a Transfer requiring Landlord’s consent under this Article 14 (any such assignee,
sublessee, or resultant Tenant described in items (A) through (E) of this Section 14.8 hereinafter referred to as a “Permitted Transferee”), provided that (i) Tenant notifies Landlord at least thirty
(30) days prior to the effective date of any such assignment or sublease and promptly supplies Landlord with any documents or information reasonably requested by Landlord regarding such transfer or Permitted Transferee as set forth above,
(ii) Tenant is not in default, beyond any applicable notice and cure period, and such assignment or sublease is not a subterfuge by Tenant to avoid its obligations under this Lease, (iii) such Permitted Transferee shall be of a character
and reputation consistent with the quality of the Building, (iv) such Permitted Transferee shall have a tangible net worth (not including goodwill as an asset) computed in accordance with generally accepted accounting principles (“Net
Worth”) at least equal to the greater of (1) the Net Worth of Original Tenant on the date of this Lease, and (2) the Net Worth of Tenant on the day immediately preceding the effective date of such assignment or sublease,
(v) no assignment or sublease relating to this Lease, whether with or without Landlord’s consent, shall relieve Tenant from any liability under this Lease, and (vi) the liability such Permitted Transferee under either an assignment or
sublease shall be joint and several with Tenant. An assignee of Tenant’s entire interest in this Lease who qualifies as a Permitted Transferee may also be referred to herein as a “Permitted Transferee Assignee.”
“Control,” as used in this Section 14.8, shall mean the ownership, directly or indirectly, of more than fifty percent (50%) of the voting securities of, or possession of the right to vote, in the ordinary direction of its
affairs, of more than fifty percent (50%) of the voting interest in, any person or entity. 
 ARTICLE 15 

SURRENDER OF PREMISES: OWNERSHIP AND 

REMOVAL OF TRADE FIXTURES 

15.1 Surrender of Premises. No act or thing done by Landlord or any agent or employee of Landlord during the Lease Term shall be
deemed to constitute an acceptance by Landlord of a surrender of the Premises unless such intent is specifically acknowledged in writing by Landlord. The delivery of keys to the Premises to Landlord or any agent or employee of Landlord shall not
constitute a surrender of the Premises or effect a termination of this Lease, whether or not the keys are thereafter retained by Landlord, and notwithstanding such delivery Tenant shall be entitled to the return of such keys at any reasonable time
upon request until this Lease shall have been properly terminated. The voluntary or other surrender of this Lease by Tenant, whether accepted by Landlord or not, or a mutual termination hereof, shall not work a merger, and at the option of Landlord
shall operate as an assignment to Landlord of all subleases or subtenancies affecting the Premises or terminate any or all such sublessees or subtenancies.

 15.2 Removal of Tenant Property by Tenant. Upon the expiration of the Lease Term,
or upon any earlier termination of this Lease, Tenant shall, subject to the provisions of this Article 15, quit and surrender possession of the Premises to Landlord in as good order and condition as when Tenant took possession and as
thereafter improved by Landlord and/or Tenant, reasonable wear and tear and repairs which are specifically made the responsibility of Landlord hereunder excepted. Upon such expiration or termination, Tenant shall, without expense to Landlord, remove
or cause to be removed from the Premises all debris and rubbish, and such items of furniture, equipment, business and trade fixtures, free-standing cabinet work, movable partitions and other articles of personal property owned by Tenant or installed
or placed by Tenant at its expense in the Premises, and such similar articles of any other persons claiming under Tenant, as Landlord may, in its sole discretion, require to be removed, and Tenant shall repair at its own expense all damage to the
Premises and Building resulting from such removal. 
 ARTICLE 16 

HOLDING OVER 
 If
Tenant holds over after the expiration of the Lease Term or earlier termination thereof, with or without the express or implied consent of Landlord, such tenancy shall be from month-to-month only, and shall not constitute a renewal hereof or an
extension for any further term, and in such case Rent shall be payable at a monthly rate equal to the greater of (i) one hundred fifty percent (150%) of the Rent applicable during the last rental period of the Lease Term under this Lease,
and (ii) one hundred fifty percent (150%) of the then fair market value applicable to the Premises as reasonably determined by Landlord. Such month-to-month tenancy shall be subject to every other applicable term, covenant and agreement
contained herein. Nothing contained in this Article 16 shall be construed as consent by Landlord to any holding over by Tenant, and Landlord expressly reserves the right to require Tenant to surrender possession of the Premises to Landlord as
provided in this Lease upon the expiration or other termination of this Lease. The provisions of this Article 16 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. If
Tenant fails to surrender the Premises upon the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from all loss, costs
(including reasonable attorneys’ fees) and liability resulting from such failure, including, without limiting the generality of the foregoing, any claims made by any succeeding tenant founded upon such failure to surrender and any lost profits
to Landlord resulting therefrom. 
 ARTICLE 17 

ESTOPPEL CERTIFICATES 

Within ten (10) days following a request in writing by Landlord, Tenant shall execute, acknowledge and deliver to Landlord an estoppel
certificate, which, as submitted by Landlord, shall be substantially in the form of Exhibit E, attached hereto (or such other form as may be 

  

					
		 	-48-	 	 KILROY REALTY

301 BRANNAN STREET
 [StumbleUpon,

required by any prospective mortgagee or purchaser of the Project, or any portion thereof), indicating therein any exceptions thereto that may exist at that time, and shall also contain any other
information reasonably requested by Landlord or Landlord’s mortgagee or prospective mortgagee. Any such certificate may be relied upon by any prospective mortgagee or purchaser of all or any portion of the Project. Tenant shall execute and
deliver whatever other instruments may be reasonably required for such purposes. Landlord may require Tenant to provide Landlord with a current financial statement and financial statements of the two (2) years prior to the current financial
statement year (i) upon the request of a prospective buyer or lender in connection with the disposition or refinance of the Building, (ii) upon a default by Tenant beyond any applicable notice and cure period expressly set forth in this
Lease, (iii) upon the filing of bankruptcy by Tenant, and/or (iv) upon Landlord’s request no more than once per calendar year for any reason other than the occurrence of the events set forth in sub-items (i) through (iii), above.
Such statements shall be prepared in the form then customarily utilized by Tenant and certified by the preparing officer of the office of Tenant’s chief financial officer that, to the best of such officer’s knowledge, such statement
accurately reflects Tenant’s financials during each applicable time period. Landlord shall keep the information contained in Tenant’s financial statements strictly confidential and shall not disclose such confidential information to any
person or entity other than (i) Landlord’s financial, legal, and construction consultants, and (ii) disclosures in filings required by the Securities Exchange Commission and customary disclosures on investor/earnings calls (or
operation of the business of Landlord). Failure of Tenant to timely execute, acknowledge and deliver such estoppel certificate or other instruments shall constitute an acceptance of the Premises and an acknowledgment by Tenant that statements
included in the estoppel certificate are true and correct, without exception. 
 ARTICLE 18 

SUBORDINATION 

Landlord covenants that there is no existing mortgage, deed of trust or other encumbrance encumbering the Project or any portion thereof as of
the date of this Lease. Accordingly, this Lease shall be subject and subordinate to all present and future ground or underlying leases of the Building or Project and to the lien of any mortgage, trust deed or other encumbrances now or hereafter in
force against the Building or Project or any part thereof, if any, and to all renewals, extensions, modifications, consolidations and replacements thereof, and to all advances made or hereafter to be made upon the security of such mortgages or trust
deeds, unless the holders of such mortgages, trust deeds or other encumbrances, or the lessors under such ground lease or underlying leases, require in writing that this Lease be superior thereto (collectively, the “Superior
Holders”); provided, however, that in consideration of and as a condition precedent to Tenant’s agreement to subordinate this Lease to any future ground or underlying lease, or mortgage, trust deed or other encumbrance, Tenant shall
receive from such future Superior Holder a subordination non-disturbance and attornment agreement in the standard form customarily employed by such Superior Holder, with such commercially reasonable modifications as may be mutually agreed to by
Tenant and such Superior Holder, which provides that so long as an event of default has not occurred and be continuing, the leasehold estate granted to Tenant and the rights of Tenant pursuant to this Lease to quiet and peaceful possession of the
Premises shall not be terminated, modified, affected or disturbed by any action which such Superior Holder may take to terminate any such ground or underlying lease or to foreclose any

 [StumbleUpon,

such mortgage, trust deed or other encumbrance, as applicable, and that any successor landlord shall recognize this Lease as being in full force and effect as if it were a direct lease between
such successor landlord and Tenant (a “SNDA”). Landlord shall use its commercially reasonable efforts to obtain non-disturbance agreement(s) in favor of Tenant from any ground lessor, mortgage holders or lien holders of Landlord who
later come into existence at any time prior to the expiration of the Lease Term. Subject to the SNDA(s) described above, Tenant covenants and agrees in the event any proceedings are brought for the foreclosure of any such mortgage or deed in lieu
thereof (or if any ground lease is terminated), to attorn, without any deductions or set-offs whatsoever, to the lienholder or purchaser or any successors thereto upon any such foreclosure sale or deed in lieu thereof (or to the ground lessor), if
so requested to do so by such purchaser or lienholder or ground lessor, and to recognize such purchaser or lienholder or ground lessor as the lessor under this Lease, provided such lienholder or purchaser or ground lessor shall agree to accept this
Lease (or enter into a new lease for the balance of the Lease Term upon the same terms and conditions) and not disturb Tenant’s occupancy, so long as Tenant timely pays the rent and observes and performs the TCCs of this Lease to be observed
and performed by Tenant. Landlord’s interest herein may be assigned as security at any time to any lienholder. Tenant shall, within five (5) days of request by Landlord, execute such further instruments or assurances as Landlord may
reasonably deem necessary to evidence or confirm the subordination or superiority of this Lease to any such mortgages, trust deeds, ground leases or underlying leases. Tenant waives the provisions of any current or future statute, rule or law which
may give or purport to give Tenant any right or election to terminate or otherwise adversely affect this Lease and the obligations of the Tenant hereunder in the event of any foreclosure proceeding or sale. 

ARTICLE 19 

DEFAULTS: REMEDIES 

19.1 Events of Default. The occurrence of any of the following shall constitute a default of this Lease by Tenant: 

19.1.1 Any failure by Tenant to pay any Rent or any other charge required to be paid under this Lease, or any part thereof, when due unless
such failure is cured within five (5) business days after notice; or 
 19.1.2 Except where a specific time period is otherwise set
forth for Tenant’s performance in this Lease, in which event the failure to perform by Tenant within such time period shall be a default by Tenant under this Section 19.1.2. any failure by Tenant to observe or perform any other
provision, covenant or condition of this Lease to be observed or performed by Tenant where such failure continues for thirty (30) days after written notice thereof from Landlord to Tenant; provided that if the nature of such default is such
that the same cannot reasonably be cured within a thirty (30) day period, Tenant shall not be deemed to be in default if it diligently commences such cure within such period and thereafter diligently proceeds to rectify and cure such default,
but in no event exceeding a period of time in excess of sixty (60) days after written notice thereof from Landlord to Tenant; or

 19.1.3 To the extent permitted by law, (i) Tenant or any guarantor of this Lease being
placed into receivership or conservatorship, or becoming subject to similar proceedings under Federal or State law, or (ii) a general assignment by Tenant or any guarantor of this Lease for the benefit of creditors, or (iii) the taking of
any corporate action in furtherance of bankruptcy or dissolution whether or not there exists any proceeding under an insolvency or bankruptcy law, or (iv) the filing by or against Tenant or any guarantor of any proceeding under an insolvency or
bankruptcy law, unless in the case of such a proceeding filed against Tenant or any guarantor the same is dismissed within sixty (60) days, or (v) the appointment of a trustee or receiver to take possession of all or substantially all of
the assets of Tenant or any guarantor, unless possession is restored to Tenant or such guarantor within thirty (30) days, or (vi) any execution or other judicially authorized seizure of all or substantially all of Tenant’s assets
located upon the Premises or of Tenant’s interest in this Lease, unless such seizure is discharged within thirty (30) days; or 

19.1.4 Abandonment of all of the Premises by Tenant; or 

19.1.5 The failure by Tenant to observe or perform according to the provisions of Articles 5, 14, 17 or 18 of this
Lease where such failure continues for more than five (5) business days after notice from Landlord; or 
 19.1.6 Tenant’s failure
to occupy the Premises within sixty (60) business days after the Lease Commencement Date. 
 The notice periods provided herein are in
lieu of, and not in addition to, any notice periods provided by law. 
 19.2 Remedies Upon Default. Upon the occurrence of any
event of default by Tenant, Landlord shall have, in addition to any other remedies available to Landlord at law or in equity (all of which remedies shall be distinct, separate and cumulative), the option to pursue any one or more of the following
remedies, each and all of which shall be cumulative and nonexclusive, without any notice or demand whatsoever. 
 19.2.1 Terminate this
Lease, in which event Tenant shall immediately surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and take
possession of the Premises and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without being liable for prosecution or any claim or damages therefor; and Landlord may recover from Tenant the
following: 
 (a) The worth at the time of award of any unpaid rent which has 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 that Tenant proves could have been reasonably avoided; plus

301 BRANNAN STREET
 [StumbleUpon,

 (c) The worth at the time of award of the amount by which the unpaid rent for the balance of the
Lease Term after the time of award exceeds the amount of such rental loss that Tenant proves could have been 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, specifically including but not limited to, brokerage commissions and advertising expenses incurred, expenses of remodeling the Premises or
any portion thereof for a new tenant, whether for the same or a different use, and any special concessions made to obtain a new tenant; 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 law. 
 The term “rent” as used in this Section 19.2 shall be deemed to be and to mean all sums of
every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or to others. As used in Sections 19.2.1(a) and (b), above, the “worth at the time of award” shall be computed by allowing
interest at the Interest Rate. As used in Section 19.2.1(c), above, the “worth at the time of award” shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of
award plus one percent 
 19.2.2 Landlord shall have the remedy described in California Civil Code Section 1951.4 (lessor may continue
lease in effect after lessee’s breach and abandonment and recover rent as it becomes due, if lessee has the right to sublet or assign, subject only to reasonable limitations). Accordingly, if Landlord does not elect to terminate this Lease on
account of any default by Tenant, Landlord may, from time to time, without terminating this Lease, enforce all of its rights and remedies under this Lease, including the right to recover all rent as it becomes due. 

19.2.3 Landlord shall at all times have the rights and remedies (which shall be cumulative with each other and cumulative and in addition to
those rights and remedies available under Sections 19.2.1 and 19.2.2, above, or any law or other provision of this Lease), without prior demand or notice except as required by applicable law, to seek any declaratory, injunctive or
other equitable relief, and specifically enforce this Lease, or restrain or enjoin a violation or breach of any provision hereof. 
 19.3
Subleases of Tenant. If Landlord elects to terminate this Lease on account of any default by Tenant, as set forth in this Article 19, Landlord shall have the right to terminate any and all subleases, licenses, concessions or
other consensual arrangements for possession entered into by Tenant and affecting the Premises or may, in Landlord’s sole discretion, succeed to Tenant’s interest in such subleases, licenses, concessions or arrangements. In the event of
Landlord’s election to succeed to Tenant’s interest in any such subleases, licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or
other consideration receivable thereunder. 
 19.4 Form of Payment After Default. Following the second (2nd) occurrence of an event of default by Tenant (beyond any applicable notice and cure periods) occurring within any 

  

					
		 	-52-	 	 KILROY REALTY

301 BRANNAN STREET
 [StumbleUpon,

twelve (12) month period, Landlord shall have the right to require that any or all subsequent amounts paid by Tenant to Landlord hereunder, whether to cure the default in question or
otherwise, be paid in the form of cash, money order, cashier’s or certified check drawn on an institution acceptable to Landlord, or by other means approved by Landlord, notwithstanding any prior practice of accepting payments in any different
form. 
 19.5 Efforts to Relet. No re-entry or repossession, repairs, maintenance, changes, alterations and additions,
reletting, appointment of a receiver to protect Landlord’s interests hereunder, or any other action or omission by Landlord shall be construed as an election by Landlord to terminate this Lease or Tenant’s right to possession, or to accept
a surrender of the Premises, nor shall same operate to release Tenant in whole or in part from any of Tenant’s obligations hereunder, unless express written notice of such intention is sent by Landlord to Tenant. Tenant hereby irrevocably
waives any right otherwise available under any law to redeem or reinstate this Lease. 
 19.6 Landlord Default.
Notwithstanding anything to the contrary set forth in this Lease, Landlord shall be in default in the performance of any obligation required to be performed by Landlord pursuant to this Lease if Landlord fails to perform such obligation within
thirty (30) days after the receipt of notice from Tenant specifying in detail Landlord’s failure to perform; provided, however, if the nature of Landlord’s obligation is such that more than thirty (30) days are required for its
performance, then Landlord shall not be in default under this Lease if it shall commence such performance within such thirty (30) day period and thereafter diligently pursues the same to completion. Upon any such default by Landlord under this
Lease, Tenant may, except as otherwise specifically provided in this Lease to the contrary, exercise any of its rights provided at law or in equity. Any award from a court or arbitrator in favor of Tenant requiring payment by Landlord which is not
paid by Landlord within the time period directed by such award, may be offset by Tenant from Rent next due and payable under this Lease; provided, however, Tenant may not deduct the amount of the award against more than fifty percent (50%) of
Base Rent next due and owing (until such time as the entire amount of such judgment is deducted) to the extent following a foreclosure or a deed-in-lieu of foreclosure. 

ARTICLE 20 

COVENANT OF QUIET ENJOYMENT 

Landlord covenants that provided Tenant is not then in default under this Lease beyond any applicable notice and cure periods, Tenant shall,
during the Lease Term, peaceably and quietly have, hold and enjoy the Premises subject to the TCCs, provisions and agreements hereof without interference by any persons lawfully claiming by or through Landlord. The foregoing covenant is in lieu of
any other covenant express or implied.

in the amount set forth in Section 21.3 below (the “L-C Amount”), which L-C shall be issued by a money-center, solvent and nationally recognized bank (a bank which
accepts deposits, maintains accounts, has a local San Francisco Bay Area, California office which will negotiate a letter of credit, and whose deposits are insured by the FDIC) reasonably acceptable to Landlord (such approved, issuing bank being
referred to herein as the “Bank”), which Bank must have a short term Fitch Rating which is not less than “Fl”, and a long term Fitch Rating which is not less than “A”(or in the event such Fitch Ratings are no
longer available, a comparable rating from Standard and Poor’s Professional Rating Service or Moody’s Professional Rating Service) (collectively, the “Bank’s Credit Rating Threshold”), and which L-C shall be
substantially in the form of Exhibit G, attached hereto. Landlord hereby approves Bridge Bank as the Bank under this Lease. Tenant shall pay all expenses, points and/or fees incurred by Tenant in obtaining the L-C. The L-C shall
(i) be “callable” at sight, irrevocable and unconditional, (ii) be maintained in effect, whether through renewal or extension, for the period commencing on the date of this Lease and continuing until the date (the “L-C
Expiration Date”) that is no less than ninety (90) days after the expiration of the Lease Term, as the same may be extended, and Tenant shall deliver a new L-C or certificate of renewal or extension to Landlord at least thirty
(30) days prior to the expiration of the L-C then held by Landlord, without any action whatsoever on the part of Landlord, (iii) be fully assignable by Landlord, its successors and assigns, (iv) permit partial draws and multiple
presentations and drawings, and (v) be otherwise subject to the Uniform Customs and Practices for Documentary Credits (1993-Rev), International Chamber of Commerce Publication #500, or the International Standby Practices-ISP 98, International
Chamber of Commerce Publication #590. Landlord, or its then managing agent, shall have the right to draw down an amount up to the face amount of the L-C if any of the following shall have occurred or be applicable: (A) such amount is due to
Landlord under the terms and conditions of this Lease, or (B) Tenant has filed a voluntary petition under the U. S. Bankruptcy Code or any state bankruptcy code (collectively, “Bankruptcy Code”), or (C) an involuntary
petition has been filed against Tenant under the Bankruptcy Code, or (D) the Bank has notified Landlord that the L-C will not be renewed or extended through the L-C Expiration Date, or (E) Tenant is placed into receivership or
conservatorship, or becomes subject to similar proceedings under Federal or State law, or (F) Tenant executes an assignment for the benefit of creditors, (G) if (1) any of the Bank’s Fitch Ratings (or other comparable ratings to
the extent the Fitch Ratings are no longer available) have been reduced below the Bank’s Credit Rating Threshold, or (2) there is otherwise a material adverse change in the financial condition of the Bank, and Tenant has failed to provide
Landlord with a replacement letter of credit, conforming in all respects to the requirements of this Article 21 (including, but not limited to, the requirements placed on the issuing Bank more particularly set forth in this
Section 21.1 above), in the amount of the applicable L-C Amount, within ten (10) days following Landlord’s written demand therefor (with no other notice or cure or grace period being applicable thereto, notwithstanding anything
in this Lease to the contrary) (H) if, following Tenant’s entering into bankruptcy, this Lease is rejected or deemed rejected under Section 365 of the Bankruptcy Code, or (I) pursuant to Article 9 above, Landlord has paid
the amount necessary to remove any lien or encumbrance arising out of the Improvements performed in accordance with the TCCs of the Work Letter, (each of the foregoing being an “L-C Draw Event”). The L-C shall be honored by the Bank
regardless of whether Tenant disputes Landlord’s right to draw upon the L-C. In addition, in the event the Bank is placed into receivership or conservatorship by the Federal Deposit Insurance Corporation or any successor or similar entity,
then, effective as of the date

such receivership or conservatorship occurs, said L-C shall be deemed to fail to meet the requirements of this Article 21, and, within ten (10) days following Landlord’s notice
to Tenant of such receivership or conservatorship (the “L-C FDIC Replacement Notice”), Tenant shall replace such L-C with a substitute letter of credit from a different issuer (which issuer shall meet or exceed the Bank’s
Credit Rating Threshold and shall otherwise be acceptable to Landlord in its reasonable discretion) and that complies in all respects with the requirements of this Article 21. If Tenant fails to replace such L-C with such conforming,
substitute letter of credit pursuant to the terms and conditions of this Section 21.1, then, notwithstanding anything in this Lease to the contrary, Landlord shall have the right to declare Tenant in default of this Lease for which there
shall be no notice or grace or cure periods being applicable thereto (other than the aforesaid ten (10) day period). Tenant shall be responsible for the payment of any and all costs incurred with the review of any replacement L-C (including
without limitation Landlord’s reasonable attorneys’ fees), which replacement is required pursuant to this Section or is otherwise requested by Tenant. 

21.2 Application of L-C. Tenant hereby acknowledges and agrees that Landlord is entering into this Lease in material reliance
upon the ability of Landlord to draw upon the L-C upon the occurrence of any L-C Draw Event. In the event of any L-C Draw Event, Landlord may, but without obligation to do so, and without notice to Tenant, draw upon the L-C, in part or in whole, to
cure any such L-C Draw Event and/or to compensate Landlord for any and all damages of any kind or nature sustained or which Landlord reasonably estimates that it will sustain resulting from Tenant’s breach or default of the Lease or other L-C
Draw Event and/or to compensate Landlord for any and all damages arising out of, or incurred in connection with, the termination of this Lease, including, without limitation, those specifically identified in Section 1951.2 of the California
Civil Code. The use, application or retention of the L-C, or any portion thereof, by Landlord shall not prevent Landlord from exercising any other right or remedy provided by this Lease or by any applicable law, it being intended that Landlord shall
not first be required to proceed against the L-C, and such L-C shall not operate as a limitation on any recovery to which Landlord may otherwise be entitled. Tenant agrees not to interfere in any way with payment to Landlord of the proceeds of the
L-C, either prior to or following a “draw” by Landlord of any portion of the L-C, regardless of whether any dispute exists between Tenant and Landlord as to Landlord’s right to draw upon the L-C. No condition or term of this Lease
shall be deemed to render the L-C conditional to justify the issuer of the L-C in failing to honor a drawing upon such L-C in a timely manner. Tenant agrees and acknowledges that (i) the L-C constitutes a separate and independent contract
between Landlord and the Bank, (ii) Tenant is not a third party beneficiary of such contract, (iii) Tenant has no property interest whatsoever in the L-C or the proceeds thereof, and (iv) in the event Tenant becomes a debtor under any
chapter of the Bankruptcy Code, Tenant is placed into receivership or conservatorship, and/or there is an event of a receivership, conservatorship or a bankruptcy filing by, or on behalf of, Tenant, neither Tenant, any trustee, nor Tenant’s
bankruptcy estate shall have any right to restrict or limit Landlord’s claim and/or rights to the L-C and/or the proceeds thereof by application of Section 502(b)(6) of the U. S. Bankruptcy Code or otherwise. 

21.3 L-C Amount; Maintenance of L-C by Tenant; Liquidated Damages. 

21.3.1 L-C Amount. The L-C Amount shall be equal to the amount set forth in Section 8 of the Summary.

 Notwithstanding anything to the contrary set forth in this Section 21.3.2, in no event shall the
L-C Amount as set forth above decrease during any period in which Tenant is in default under this Lease, but such decrease shall take place after such default is cured, provided that no such decrease shall thereafter take effect in the event this
Lease is terminated early due to such default by Tenant. 
 21.3.3 In General. If, as a result of any drawing by Landlord of
all or any portion of the L-C, the amount of the L-C shall be less than the L-C Amount, Tenant shall, within five (5) days thereafter, provide Landlord with additional letter(s) of credit in an amount equal to the deficiency, and any such
additional letter(s) of credit shall comply with all of the provisions of this Article 21, and if Tenant fails to comply with the foregoing, the same shall be subject to the terms of Section 21.3.4 below. Tenant further covenants
and warrants that it will neither assign nor encumber the L-C or any part thereof and that neither Landlord nor its successors or assigns will be bound by any such assignment, encumbrance, attempted assignment or attempted encumbrance. Without
limiting the generality of the foregoing, if the L-C expires earlier than the L-C Expiration Date, Landlord will accept a renewal thereof (such renewal letter of credit to be in effect and delivered to Landlord, as applicable, not later than sixty
(60) days prior to the expiration of the L-C), which shall be irrevocable and automatically renewable as above provided through the L-C Expiration Date upon the same terms as the expiring L-C or such other terms as may be acceptable to Landlord
in its sole discretion. If Tenant exercises its option to extend the Lease Term pursuant to Section 2.2 of this Lease, then not later than one hundred twenty (120) days prior to the commencement of the Option Term, Tenant shall
deliver to Landlord a new L-C or certificate of renewal or extension evidencing the L-C Expiration Date

as one hundred twenty (120) days after the expiration of the Option Term. However, if the L-C is not timely renewed, or if Tenant fails to maintain the L-C in the amount and in accordance
with the terms set forth in this Article 21, Landlord shall have the right to either (x) present the L-C to the Bank in accordance with the terms of this Article 21, and the proceeds of the L-C may be applied by Landlord against
any Rent payable by Tenant under this Lease that is not paid when due and/or to pay for all losses and damages that Landlord has suffered or that Landlord reasonably estimates that it will suffer as a result of any breach or default by Tenant under
this Lease, or (y) pursue its remedy under Section 21.3.4 below. In the event Landlord elects to exercise its rights under the foregoing item (x), (I) any unused proceeds shall constitute the property of Landlord (and not
Tenant’s property or, in the event of a receivership, conservatorship, or a bankruptcy filing by Tenant, property of such receivership, conservatorship or Tenant’s bankruptcy estate) and need not be segregated from Landlord’s other
assets, and (II) Landlord agrees to pay to Tenant within thirty (30) days after the L-C Expiration Date the amount of any proceeds of the L-C received by Landlord and not applied against any Rent payable by Tenant under this Lease that was
not paid when due or used to pay for any losses and/or damages suffered by Landlord (or reasonably estimated by Landlord that it will suffer) as a result of any breach or default by Tenant under this Lease; provided, however, that if prior to the
L-C Expiration Date a voluntary petition is filed by Tenant, or an involuntary petition is filed against Tenant by any of Tenant’s creditors, under the Bankruptcy Code, then Landlord shall not be obligated to make such payment in the amount of
the unused L-C proceeds until either all preference issues relating to payments under this Lease have been resolved in such bankruptcy or reorganization case or such bankruptcy or reorganization case has been dismissed. In the event of an assignment
by Tenant of its interest in this Lease (and irrespective of whether Landlord’s consent is required for such assignment), the acceptance of any replacement or substitute letter of credit by Landlord from the assignee shall be subject to
Landlord’s prior written approval, in Landlord’s reasonable discretion, and the attorney’s fees incurred by Landlord in connection with such determination shall be payable by Tenant to Landlord within ten (10) days of billing.

 21.4 Transfer and Encumbrance. The L-C shall also provide that Landlord may, at any time and without notice to Tenant and
without first obtaining Tenant’s consent thereto, transfer (one or more times) all or any portion of its interest in and to the L-C to another party, person or entity, regardless of whether or not such transfer is from or as a part of the
assignment by Landlord of its rights and interests in and to this Lease. In the event of a transfer of Landlord’s interest in under this Lease, Landlord shall transfer the L-C, in whole or in part, to the transferee and thereupon Landlord
shall, without any further agreement between the parties, be released by Tenant from all liability therefor, and it is agreed that the provisions hereof shall apply to every transfer or assignment of the whole of said L-C to a new landlord. In
connection with any such transfer of the L-C by Landlord, Tenant shall, at Tenant’s sole cost and expense, execute and submit to the Bank such applications, documents and instruments as may be necessary to effectuate such transfer and, Tenant
shall be responsible for paying the Bank’s transfer and processing fees in connection therewith; provided that, Landlord shall have the right (in its sole discretion), but not the obligation, to pay such fees on behalf of Tenant, in which case
Tenant shall reimburse Landlord within ten (10) days after Tenant’s receipt of an invoice from Landlord therefor. 
 21.5
L-C Not a Security Deposit. Landlord and Tenant (1) acknowledge and agree that in no event or circumstance shall the L-C or any renewal thereof or substitute therefor or any 

  

					
		 	-57-	 	 KILROY REALTY

301 BRANNAN STREET
 [StumbleUpon,
Inc.]

 
proceeds thereof be deemed to be or treated as a “security deposit” under any law applicable to security deposits in the commercial context, including, but not limited to,
Section 1950.7 of the California Civil Code, as such Section now exists or as it may be hereafter amended or succeeded (the “Security Deposit Laws”), (2) acknowledge and agree that the L-C (including any renewal thereof or
substitute therefor or any proceeds thereof) is not intended to serve as a security deposit, and the Security Deposit Laws shall have no applicability or relevancy thereto, and (3) waive any and all rights, duties and obligations that any such
party may now, or in the future will, have relating to or arising from the Security Deposit Laws. Tenant hereby irrevocably waives and relinquishes the provisions of Section 1950.7 of the California Civil Code and any successor statue, and all
other provisions of law, now or hereafter in effect, which (x) establish the time frame by which a landlord must refund a security deposit under a lease, and/or (y) provide that a landlord may claim from a security deposit only those sums
reasonably necessary to remedy defaults in the payment of rent, to repair damage caused by a tenant or to clean the premises, it being agreed that Landlord may, in addition, claim those sums specified in this Article 21 and/or those sums
reasonably necessary to (a) compensate Landlord for any loss or damage caused by Tenant’s breach of this Lease, including any damages Landlord suffers following termination of this Lease, and/or (b) compensate Landlord for any and all
damages arising out of, or incurred in connection with, the termination of this Lease, including, without limitation, those specifically identified in Section 1951.2 of the California Civil Code. 

21.6 Non-interference By Tenant. Tenant agrees not to interfere in any way with any payment to Landlord of the proceeds of the
L-C, either prior to or following a “draw” by Landlord of all or any portion of the L-C, regardless of whether any dispute exists between Tenant and Landlord as to Landlord’s right to draw down all or any portion of the L-C. No
condition or term of this Lease shall be deemed to render the L-C conditional and thereby afford the Bank a justification for failing to honor a drawing upon such L-C in a timely manner. Tenant shall not
request or instruct the Bank of any L-C to refrain from paying sight draft(s) drawn under such L-C. 
 21.7 Waiver of Certain
Relief. Tenant unconditionally and irrevocably waives (and as an independent covenant hereunder, covenants not to assert) any right to claim or obtain any of the following relief in connection with the L-C: 

21.7.1 A temporary restraining order, temporary injunction, permanent injunction, or other order that would prevent, restrain or restrict the
presentment of sight drafts drawn under any L-C or the Bank’s honoring or payment of sight draft(s); or 
 21.7.2 Any attachment,
garnishment, or levy in any manner upon either the proceeds of any L-C or the obligations of the Bank (either before or after the presentment to the Bank of sight drafts drawn under such L-C) based on any theory whatever. 

21.8 Remedy for Improper Drafts. Tenant’s sole remedy in connection with the improper presentment or payment of sight
drafts drawn under any L-C shall be the right to obtain from Landlord a refund of the amount of any sight draft(s) that were improperly presented or the proceeds of which were misapplied, together with interest at the Interest Rate (as defined
below) and reasonable actual out-of-pocket attorneys’ fees, provided that at the time of such refund, Tenant increases the amount of such L-C to the amount (if any) then required under the 

  

					
		 	-58-	 	 KILROY REALTY

301 BRANNAN STREET
 [StumbleUpon,
Inc.]

 
applicable provisions of this Lease. Tenant acknowledges that the presentment of sight drafts drawn under any L-C, or the Bank’s payment of sight drafts drawn under such L-C, could not under
any circumstances cause Tenant injury that could not be remedied by an award of money damages, and that the recovery of money damages would be an adequate remedy therefor. In the event Tenant shall be entitled to a refund as aforesaid and Landlord
shall fail to make such payment within ten (10) business days after demand, Tenant shall have the right to deduct the amount thereof together with interest thereon at the Interest Rate from the next installment(s) of Base Rent.

ARTICLE 23 

SIGNS 
 23.1
Full Floors. Subject to Landlord’s prior written approval, in its reasonable discretion, and provided all signs are in keeping with the quality, design and style of the Building and Project, Tenant, if the Premises comprise an
entire floor of the Building, at its sole cost and expense, may install identification signage anywhere in the Premises including in the elevator lobby of the Premises, provided that such signs must not be visible from the exterior of the Building.

 23.2 Multi-Tenant Floors. If other tenants occupy space on the floor on which the Premises is located, Tenant’s
identifying signage shall be provided by Landlord, at Landlord’s cost (as opposed to any replacement suite signage requested by Tenant during the Lease Term, the cost of which shall be Tenant’s), and such signage shall be comparable to
that used by Landlord for other similar floors in the Building and shall comply with Landlord’s Building standard signage program. 

23.3 Prohibited Signage and Other Items. Any signs, notices, logos, pictures, names or advertisements which are installed and
that have not been separately approved by Landlord may be removed without notice by Landlord at the sole expense of Tenant. Any signs, window coverings, or blinds (even if the same are located behind the Landlord-approved window coverings for the
Building), or other items visible from the exterior of the Premises or Building, shall be subject to the prior approval of Landlord, in its sole discretion. 

23.4 Building Directory. Tenant shall be entitled to reasonable signage on the Building directory located in the main Building
lobby. Landlord shall install on the Building directory, at Landlord’s sole cost and expense, the names initially requested by Tenant, provided that any modification to such names requested by Tenant subsequent to the initial installation of
the same shall be at Tenant’s sole cost and expense. 
 23.5 Exterior Signage. Subject to the terms of this
Section 23.5, Landlord hereby grants to the Original Tenant the right to install identification signage displaying the name and logo of the Original Tenant (or its Permitted Transferee) on the exterior of the Building

  

					
		 	-59-	 	 KILROY REALTY

 [StumbleUpon,
Inc.]

 
(collectively, the “Exterior Signage”) in locations determined by Landlord. The Exterior Signage shall be subject to Landlord’s prior written approval, in its reasonable
discretion, and shall be consistent with the quality, design and style of the Building and Project. The Exterior Signage shall also be subject to, and comply with, all applicable “Laws,” as that term is defined in Article 24 below.
In no event shall the approval by the City of San Francisco (the “City”) or other applicable governmental authorities of the Exterior Signage be deemed a condition precedent to the effectiveness of this Lease (Tenant hereby
acknowledging the historical nature of the Building), and if the City or other applicable governmental authorities do not approve the Exterior Signage (as the same may be altered by Tenant to obtain such approval), Tenant shall not be entitled to
the Exterior Signage hereunder. Further, Tenant shall be responsible, at Tenant’s sole cost, for obtaining any applicable permits or other governmental approval(s) applicable to, or required for, the Exterior Signage. Tenant shall be
responsible for all costs and expenses incurred in connection with the design, construction, installation, repair, operation (including utilities costs), maintenance, compliance with applicable Laws, and removal of the Exterior Signage
(collectively, “Tenant’s Signage Costs”). Landlord shall have the right to bill Tenant for Tenant’s Signage Costs, and Tenant shall deliver payment for such bill to Landlord within ten (10) days of Landlord’s
delivery of such bill to Tenant. The rights set forth in this Section 23.5 shall be personal to Original Tenant and any Permitted Transferee and may not be assigned to any other assignee, sublessee or other transferee of Original
Tenant’s interest in this Lease. In addition, Tenant’s signage rights set forth in this Section 23.5 shall terminate at any time during the Lease Term that Original Tenant (or its Permitted Transferee) fails to physically
occupy at least two (2) of the floors which constitute the Premises or that Tenant has subleased one-half (1/2) or more of the rentable square footage of the Premises. Notwithstanding the foregoing, the Exterior Signage shall not be
changed without Landlord’s prior written approval, in its reasonable discretion, provided that in no event shall any name or logo on the Exterior Signage be an “Objectionable Name or Logo,” as that term is defined below. The term
“Objectionable Name or Logo,” shall mean any name or logo (or other sign content) which relates to an entity which is of a character or reputation, or is associated with a political orientation or faction, which is inconsistent with
the quality of the Building or which would otherwise reasonably offend a landlord of comparable first-class institutionally-owned office buildings in the vicinity of the Building. Upon the expiration of the Lease Term or the earlier termination of
Tenant’s signage rights under this Section 23.5, Tenant shall, at Tenant’s sole cost and expense, remove the Exterior Signage and repair any and all damage to the Building caused by such removal and restore all affected areas
to their original condition. In the event that Tenant fails to remove the Exterior Signage upon the expiration or earlier termination of the Lease Term, or within fifteen (15) days of receipt of written notice from Landlord informing Tenant
that Tenant’s rights under this Section 23.5 are being terminated, Landlord shall have the right to, at Tenant’s sole cost and expense, remove the Exterior Signage and complete the repairs that are required of Tenant under this
Section 23.5, and deliver an invoice to Tenant for the costs of such removal and repair, which invoice shall be payable by Tenant within ten (10) days from the date of Landlord’s delivery of such invoice(s) to Tenant.

 ARTICLE 24 

COMPLIANCE WITH LAW 

Tenant shall not do anything or suffer anything to be done in or about the Premises or the Project which will in any way conflict with any
law, statute, ordinance or other governmental rule, regulation or requirement now in force or which may hereafter be enacted or promulgated (collectively, “Applicable Laws”). At its sole cost and expense, Tenant shall promptly
comply with all such Applicable Laws which relate to (i) Tenant’s use of the Premises for non-general office use, (ii) the Alterations or the Improvements in the Premises, or (iii) the Base Building, but, as to the Base Building,
only to the extent such obligations are triggered by Tenant’s Alterations, the Improvements, or use of the Premises for non-general office use. Should any standard or regulation now or hereafter be imposed on Landlord or Tenant by a state,
federal or local governmental body charged with the establishment, regulation and enforcement of occupational, health or safety standards for employers, employees, landlords or tenants, then Tenant agrees, at its sole cost and expense, to comply
promptly with such standards or regulations. The judgment of any court of competent jurisdiction or the admission of Tenant in any judicial action, regardless of whether Landlord is a party thereto, that Tenant has violated any of said governmental
measures, shall be conclusive of that fact as between Landlord and Tenant. Landlord shall comply with all Applicable Laws relating to the Base Building, provided that compliance with such Applicable Laws is not the responsibility of Tenant under
this Lease, and provided further that Landlord’s failure to comply therewith (w) would prohibit Tenant from obtaining or maintaining a building permit or a certificate of occupancy or its legal equivalent for the Premises, or
(x) would (on other than a de minimis basis) negatively affect the safety of Tenant’s employees or create a health hazard for Tenant’s employees, or (y) would materially impair Tenant’s use and occupancy of or reasonable
access to the Premises for the Permitted Use, or (z) would materially impair Tenant’s ability to perform, or materially delay Tenant’s performance of, Alterations in the Premises; provided that, Landlord shall have no
obligation to make any changes to the Premises as may be required to be made in connection with Alterations in the Premises. Landlord shall be permitted to include in Operating Expenses any costs or expenses incurred by Landlord under this
Article 24 to the extent consistent with the terms of Section 4.2.4, above. 
 ARTICLE 25 

LATE CHARGES 
 If
any installment of Rent or any other sum due from Tenant shall not be received by Landlord or Landlord’s designee when due, then Tenant shall pay to Landlord a late charge equal to five percent (5%) of the overdue amount plus any
attorneys’ fees incurred by Landlord by reason of Tenant’s failure to pay Rent and/or other charges when due hereunder; provided, however, with regard to the first such failure in any twelve (12) month period, Landlord will waive such
late charge to the extent Tenant cures such failure within five (5) days following Tenant’s receipt of written notice from Landlord that the same was not received when due. The late charge shall be deemed Additional Rent and the right to
require it shall be in addition to all of Landlord’s other rights and remedies hereunder or at law and shall not be construed as liquidated damages or as limiting Landlord’s remedies in any manner. In addition to the late

  

					
		 	-61-	 	 KILROY REALTY

 [StumbleUpon,
Inc.]

 
charge described above, any Rent or other amounts owing hereunder which are not paid within ten (10) days after the date they are due shall bear interest from the date when due until paid at
the “Interest Rate.” For purposes of this Lease, the “Interest Rate” shall be an annual rate equal to the lesser of (i) the annual “Bank Prime Loan” rate cited in the Federal Reserve Statistical
Release Publication H. 15(519), published weekly (or such other comparable index as Landlord and Tenant shall reasonably agree upon if such rate ceases to be published), plus four (4) percentage points, and (ii) the highest rate permitted
by applicable law. 
 ARTICLE 26 

LANDLORD’S RIGHT TO CURE DEFAULT: PAYMENTS BY TENANT 

26.1 Landlord’s Cure. All covenants and agreements to be kept or performed by Tenant under this Lease shall be performed by
Tenant at Tenant’s sole cost and expense and without any reduction of Rent, except to the extent, if any, otherwise expressly provided herein. If Tenant shall fail to perform any obligation under this Lease, and such failure shall continue in
excess of the time allowed under Section 19.1.2, above, unless a specific time period is otherwise stated in this Lease, Landlord may, but shall not be obligated to, make any such payment or perform any such act on Tenant’s part
without waiving its rights based upon any default of Tenant and without releasing Tenant from any obligations hereunder. 
 26.2
Tenant’s Reimbursement. Except as may be specifically provided to the contrary in this Lease, Tenant shall pay to Landlord, upon delivery by Landlord to Tenant of statements therefor: (i) sums equal to expenditures reasonably
made and obligations incurred by Landlord in connection with the remedying by Landlord of Tenant’s defaults pursuant to the provisions of Section 26.1; (ii) sums equal to all losses, costs, liabilities, damages and expenses
referred to in Section 10.1 of this Lease; and (iii) in connection with any default by Tenant under this Lease, sums equal to all expenditures made and obligations incurred by Landlord in collecting or attempting to collect the Rent
or in enforcing or attempting to enforce any rights of Landlord under this Lease or pursuant to law, including, without limitation, all legal fees and other amounts so expended. Tenant’s obligations under this Section 26.2 shall
survive the expiration or sooner termination of the Lease Term. 
 ARTICLE 27 

ENTRY BY LANDLORD 

Landlord reserves the right at all reasonable times (during Building Hours with respect to items (i) and (ii) below) and upon at
least twenty-four (24) hours prior notice to Tenant (except in the case of an emergency) to enter the Premises, after first checking in with Tenant’s receptionist or other representative of Tenant (if such receptionist or other
representative is available at the time of such entry), to (i) inspect them; (ii) show the Premises to prospective purchasers, or to current or prospective mortgagees, ground or underlying lessors or insurers, or during the last twelve
(12) months of the Lease Term, to prospective tenants; (iii) post notices of nonresponsibility; or (iv) alter, improve or repair the Premises or the Building if necessary to comply with current building codes or other Applicable Laws,
or for structural alterations, repairs or improvements to the Building or the Building’s systems and equipment.

 [StumbleUpon,

Notwithstanding anything to the contrary contained in this Article 27, Landlord may enter the Premises at any time to (A) perform services required of Landlord, including janitorial
service; (B) take possession due to any breach of this Lease in the manner provided herein; and (C) perform any covenants of Tenant which Tenant fails to perform. Landlord may make any such entries without the abatement of Rent, except as
otherwise provided in this Lease, and may take such reasonable steps as required to accomplish the stated purposes; provided, however, except for (x) emergencies, (y) repairs, alterations, improvements or additions required by governmental
or quasi-governmental authorities or court order or decree, or (z) repairs which are the obligation of Tenant hereunder, any such entry shall be performed in a manner so as not to unreasonably interfere with Tenant’s use of the Premises
and shall be performed after normal business hours if reasonably practical. With respect to items (y) and (z) above, Landlord shall use commercially reasonable efforts to not materially interfere with Tenant’s use of, or access to,
the Premises. Tenant hereby waives any claims for damages or for any injuries or inconvenience to or interference with Tenant’s business, lost profits, any loss of occupancy or quiet enjoyment of the Premises, and any other loss occasioned
thereby. For each of the above purposes, Landlord shall at all times have a key with which to unlock all the doors in the Premises, excluding Tenant’s vaults, safes and special security areas designated in advance by Tenant. In an emergency,
Landlord shall have the right to use any means that Landlord may deem proper to open the doors in and to the Premises. Any entry into the Premises by Landlord in the manner hereinbefore described shall not be deemed to be a forcible or unlawful
entry into, or a detainer of, the Premises, or an actual or constructive eviction of Tenant from any portion of the Premises. No provision of this Lease shall be construed as obligating Landlord to perform any repairs, alterations or decorations
except as otherwise expressly agreed to be performed by Landlord herein. 
 ARTICLE 28 

TENANT PARKING 

Tenant may rent from Landlord, on a monthly basis throughout the Lease Term, commencing on the Initial Lease Commencement Date, up to the
amount of non-exclusive unreserved parking passes set forth in Section 9 of the Summary, all of which parking passes shall pertain to the Project parking facility. Tenant shall pay to Landlord (or its designee) for such parking passes on a
monthly basis at the prevailing rate charged from time to time at the location of such parking passes. In addition to any fees that may be charged to Tenant in connection with its parking of automobiles in the Project parking facility, Tenant shall
be responsible for the full amount of any taxes imposed by any governmental authority in connection with the renting of any parking passes by Tenant or the use of the parking facility by Tenant. Tenant’s continued right to use the parking
passes is conditioned upon Tenant abiding by all rules and regulations which are prescribed from time to time for the orderly operation and use of the parking facility where the parking passes are located, including any sticker or other
identification system established by Landlord, Tenant’s cooperation in seeing that Tenant’s employees and visitors also comply with such rules and regulations and Tenant not being in default under this Lease. Landlord specifically reserves
the right to change the size, configuration, design, layout and all other aspects of the Project parking facility at any time and Tenant acknowledges and agrees that Landlord may, without incurring any liability to Tenant and without any abatement
of Rent under this Lease, from time to time, close-off or restrict

access to the Project parking facility for purposes of permitting or facilitating any such construction, alteration or improvements. Landlord may delegate its responsibilities hereunder to a
parking operator in which case such parking operator shall have all the rights of control attributed hereby to the Landlord. The parking passes rented by Tenant pursuant to this Article 28 are provided to Tenant solely for use by
Tenant’s own personnel and such passes may not be transferred, assigned, subleased or otherwise alienated by Tenant without Landlord’s prior approval. 

ARTICLE 29 

MISCELLANEOUS PROVISIONS 

29.1 Terms; Captions. The words “Landlord” and “Tenant” as used herein shall include the plural as well as
the singular. The necessary grammatical changes required to make the provisions hereof apply either to corporations or partnerships or individuals, men or women, as the case may require, shall in all cases be assumed as though in each case fully
expressed. The captions of Articles and Sections are for convenience only and shall not be deemed to limit, construe, affect or alter the meaning of such Articles and Sections. 

29.2 Binding Effect. Subject to all other provisions of this Lease, each of the covenants, conditions and provisions of this
Lease shall extend to and shall, as the case may require, bind or inure to the benefit not only of Landlord and of Tenant, but also of their respective heirs, personal representatives, successors or assigns, provided this clause shall not permit any
assignment by Tenant contrary to the provisions of Article 14 of this Lease. 
 29.3 No Air Rights. No rights to any
view or to light or air over any property, whether belonging to Landlord or any other person, are granted to Tenant by this Lease. If at any time any windows of the Premises are temporarily darkened or the light or view therefrom is obstructed by
reason of any repairs, improvements, maintenance or cleaning in or about the Project, the same shall be without liability to Landlord and without any reduction or diminution of Tenant’s obligations under this Lease. 

29.4 Modification of Lease. Should any current or prospective mortgagee or ground lessor for the Building or Project require a
modification of this Lease, which modification will not cause an increased cost or expense to Tenant or in any other way materially and adversely change the rights and obligations of Tenant hereunder, then and in such event, Tenant agrees that this
Lease may be so modified and agrees to execute whatever documents are reasonably required therefor and to deliver the same to Landlord within ten (10) days following a request therefor. At the request of Landlord or any mortgagee or ground
lessor, Tenant agrees to execute a short form of Lease and deliver the same to Landlord within ten (10) days following the request therefor. 

29.5 Transfer of Landlord’s Interest. Tenant acknowledges that Landlord has the right to transfer all or any portion of its
interest in the Project or Building and in this Lease, and Tenant agrees that in the event of any such transfer, Landlord shall automatically be released from all liability thereafter arising under this Lease and Tenant agrees to look solely to such
transferee for the performance of Landlord’s obligations hereunder after the date of transfer and 

  

					
		 	-64-	 	 KILROY REALTY

301 BRANNAN STREET
 [StumbleUpon,
Inc.]

 
such transferee shall be deemed to have fully assumed and be liable for all obligations of this Lease to be performed by Landlord, including the return of any Security Deposit, and Tenant shall
attorn to such transferee. Tenant further acknowledges that Landlord may assign its interest in this Lease to a mortgage lender as additional security and agrees that such an assignment shall not release Landlord from its obligations hereunder and
that Tenant shall continue to look to Landlord for the performance of its obligations hereunder. 
 29.6 Prohibition Against Recording
or Publication. Except as provided in Section 29.4 of this Lease, neither this Lease, nor any memorandum, affidavit or other writing with respect thereto, shall be recorded or otherwise published by Tenant or by anyone acting
through, under or on behalf of Tenant. 
 29.7 Landlord’s Title. Landlord’s title is and always shall be paramount
to the title of Tenant. Nothing herein contained shall empower Tenant to do any act which can, shall or may encumber the title of Landlord. 

29.8 Relationship of Parties. Nothing contained in this Lease shall be deemed or construed by the parties hereto or by any third
party to create the relationship of principal and agent, partnership, joint venturer or any association between Landlord and Tenant. 
 29.9
Application of Payments. Landlord shall have the right to apply payments received from Tenant pursuant to this Lease, regardless of Tenant’s designation of such payments, to satisfy any obligations of Tenant hereunder, in such
order and amounts as Landlord, in its sole discretion, may elect. 
 29.10 Time of Essence. Time is of the essence with
respect to the performance of every provision of this Lease in which time of performance is a factor. 
 29.11 Partial
Invalidity. If any term, provision or condition contained in this Lease shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application of such term, provision or condition to persons or circumstances other
than those with respect to which it is invalid or unenforceable, shall not be affected thereby, and each and every other term, provision and condition of this Lease shall be valid and enforceable to the fullest extent possible permitted by law. 

29.12 No Warranty. In executing and delivering this Lease, Tenant has not relied on any representations, including, but not
limited to, any representation as to the amount of any item comprising Additional Rent or the amount of the Additional Rent in the aggregate or that Landlord is furnishing the same services to other tenants, at all, on the same level or on the same
basis, or any warranty or any statement of Landlord which is not set forth herein or in one or more of the exhibits attached hereto. 

29.13 Landlord Exculpation. The liability of Landlord or the Landlord Parties to Tenant for any default by Landlord under this
Lease or arising in connection herewith or with Landlord’s operation, management, leasing, repair, renovation, alteration or any other matter relating to the Project or the Premises shall be limited solely and exclusively to an amount which is
equal to the lesser of (a) the interest of Landlord in the Building or (b) the equity interest Landlord would have in the Building if the Building were encumbered by third-party debt in an 

  

					
		 	-65-	 	 KILROY REALTY

amount equal to eighty percent (80%) of the value of the Building (as such value is determined by Landlord), provided that in no event shall such liability extend to any sales or insurance
proceeds received by Landlord or the Landlord Parties in connection with the Project, Building or Premises. Neither Landlord, nor any of the Landlord Parties shall have any personal liability therefor, and Tenant hereby expressly waives and releases
such personal liability on behalf of itself and all persons claiming by, through or under Tenant. The limitations of liability contained in this Section 29.13 shall inure to the benefit of Landlord’s and the Landlord Parties’
present and future partners, beneficiaries, officers, directors, trustees, shareholders, agents and employees, and their respective partners, heirs, successors and assigns. Under no circumstances shall any present or future partner of Landlord (if
Landlord is a partnership), or trustee or beneficiary (if Landlord or any partner of Landlord is a trust), have any liability for the performance of Landlord’s obligations under this Lease. Notwithstanding any contrary provision herein, neither
Landlord nor the Landlord Parties shall be liable under any circumstances for injury or damage to, or interference with, Tenant’s business, including but not limited to, loss of profits, loss of rents or other revenues, loss of business
opportunity, loss of goodwill or loss of use, in each case, however occurring. 
 29.14 Entire Agreement. It is understood and
acknowledged that there are no oral agreements between the parties hereto affecting this Lease and this Lease constitutes the parties’ entire agreement with respect to the leasing of the Premises and supersedes and cancels any and all previous
negotiations, arrangements, brochures, agreements and understandings, if any, between the parties hereto or displayed by Landlord to Tenant with respect to the subject matter thereof, and none thereof shall be used to interpret or construe this
Lease. None of the terms, covenants, conditions or provisions of this Lease can be modified, deleted or added to except in writing signed by the parties hereto. 

29.15 Right to Lease. Landlord reserves the absolute right to effect such other tenancies in the Project as Landlord in the
exercise of its sole business judgment shall determine to best promote the interests of the Building or Project. Tenant does not rely on the fact, nor does Landlord represent, that any specific tenant or type or number of tenants shall, during the
Lease Term, occupy any space in the Building or Project. 
 29.16 Force Majeure. Any prevention, delay or stoppage due to
strikes, lockouts, labor disputes, acts of God, inability to obtain services, labor, or materials or reasonable substitutes therefor, governmental actions, civil commotions, fire or other casualty, and other causes beyond the reasonable control of
the party obligated to perform, except with respect to the obligations imposed with regard to Rent and other charges to be paid by Tenant pursuant to this Lease and except as to Tenant’s obligations under Articles 5 and 24 of this Lease
(collectively, a “Force Majeure”), notwithstanding anything to the contrary contained in this Lease, shall excuse the performance of such party for a period equal to any such prevention, delay or stoppage and, therefore, if this
Lease specifies a time period for performance of an obligation of either party, that time period shall be extended by the period of any delay in such party’s performance caused by a Force Majeure. 

29.17 Waiver of Redemption by Tenant. Tenant hereby waives, for Tenant and for all those claiming under Tenant, any and all
rights 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 Premises after any termination of this Lease.

each individual executing this Lease on behalf of Tenant hereby represents and warrants that Tenant is a duly formed and existing entity qualified to do business in California and that Tenant has full right and authority to execute and deliver this

PROCEEDINGS OR ACTION FOR NONPAYMENT OF BASE RENT OR ADDITIONAL RENT, TENANT SHALL NOT INTERPOSE ANY COUNTERCLAIM OF ANY NATURE OR DESCRIPTION (UNLESS SUCH COUNTERCLAIM SHALL BE MANDATORY) IN ANY SUCH PROCEEDING OR ACTION, BUT SHALL BE RELEGATED TO
AN INDEPENDENT ACTION AT LAW. 
 29.23 Submission of Lease. Submission of this instrument for examination or signature by
Tenant does not constitute a reservation of, option for or option to lease, and it is not effective as a lease or otherwise until execution and delivery by both Landlord and Tenant.

excepting only the real estate brokers or agents specified in Section 12 of the Summary (the “Broker”), and that they know of no other real estate broker or agent who

from any and all claims, demands, losses, liabilities, lawsuits, judgments, costs and expenses (including without limitation reasonable attorneys’ fees) with respect to any leasing commission or equivalent compensation alleged to be owing on
account of any dealings with any real estate broker or agent, other than the Broker, occurring by, through, or under the indemnifying party. 

29.25 Independent Covenants. This Lease shall be construed as though the covenants herein between Landlord and Tenant are

structures in the Building, limit or eliminate access to portions of the Project, including portions of the common areas, or perform work in the Building, which work may create noise, dust or leave debris in the Building. Tenant hereby agrees that
such Renovations and Landlord’s actions in connection with such Renovations shall in no way constitute a constructive eviction of Tenant nor entitle Tenant to any abatement of Rent. Landlord shall have no responsibility or for any reason be
liable to Tenant for any direct or indirect injury to or interference with Tenant’s business arising from the Renovations, nor shall Tenant be entitled to any compensation or damages from Landlord for loss of the use of the whole or any part of

damages, liabilities, costs and expenses, including, without limitation, reasonable attorneys’ fees and costs, arising from Tenant’s breach of this warranty and representation. 

29.32 Communications and Computer Lines. Tenant may install, maintain, replace, remove or use any communications or computer
wires and cables (collectively, the “Lines”) at the Project in or serving the Premises, provided that (i) Tenant shall obtain Landlord’s prior written consent, use an experienced and qualified contractor reasonably
designated by Landlord, and comply with all of the other provisions of Articles 7 and 8 of this Lease, (ii) an acceptable number of spare Lines and space for additional Lines shall be maintained for existing and future occupants
of the Project, as determined in Landlord’s reasonable opinion, (iii) the Lines therefor (including riser cables) shall be (x) appropriately insulated to prevent excessive electromagnetic fields or radiation, (y) surrounded by a
protective conduit reasonably acceptable to Landlord, and (z) identified in accordance with the “Identification Requirements,” as that term is set forth hereinbelow, (iv) any Lines installed by or on behalf of Tenant servicing
the Premises shall comply with all applicable governmental laws and regulations, and (v) Tenant shall pay all costs in connection therewith. All Lines shall be clearly marked with adhesive plastic labels (or plastic tags attached to such Lines
with wire) to show Tenant’s name, suite number, telephone number and the name of the person to contact in the case of an emergency (A) every four feet (4’) outside the Premises (specifically including, but not limited to, the
electrical room risers and other Common Areas), and (B) at the Lines’ termination point(s) (collectively, the “Identification Requirements”). Landlord reserves the right to require that Tenant remove any Lines located in
or serving the Premises which are installed by or on behalf of Tenant in

right to require that Tenant remove any and all Lines installed by or on behalf of Tenant located in or serving the Premises upon the expiration of the Lease Term or upon any earlier termination of this Lease. 

29.33 Hazardous Substances.

against any liability, obligation, damage or costs, including without limitation, attorneys’ fees and costs, resulting directly or indirectly from any use, presence, removal or disposal of any Hazardous Materials or breach of any provision of

WORK LETTER 
 This Work
Letter shall set forth the terms and conditions relating to the construction of the Premises. This Work Letter is essentially organized chronologically and addresses the issues of the construction of the Premises, in sequence, as such issues will
arise during the actual construction of the Premises. All references in this Work Letter to Articles or Sections of “this Lease” shall mean the relevant portions of Articles 1 through 29 of the Office Lease to which this Work Letter
is attached as Exhibit B and of which this Work Letter forms a part, and all references in this Work Letter to Articles or Sections of “this Work Letter” shall mean the relevant portions of Articles 1 through 5 of this
Work Letter. Landlord and Tenant acknowledge and agree that, at Tenant’s election, the Initial Premises and the Must-Take Space may be constructed separately, in which case all of the provisions of this Work Letter shall apply separately to the
construction of the Initial Premises and the Must-Take Space, as applicable. Without limiting the generality of the foregoing, all references in this Work Letter to the “Premises” shall mean the Initial Premises or the Must-Take Space, as
applicable, if Tenant is constructing the Initial Premises and the Must-Take Space separately, or the entire Premises, if Tenant is constructing the entire Premises simultaneously. 

ARTICLE 1 
 DELIVERY OF
THE PREMISES 
 Tenant acknowledges that Tenant has thoroughly examined the Initial Premises. Upon the full execution and delivery of
this Lease by Landlord and Tenant, Landlord shall deliver the Initial Premises and Tenant shall accept the Initial Premises from Landlord in its presently existing, “as-is” condition as of the date of this Lease. In addition, Tenant
currently occupies and, as of the date of this Lease, is fully aware of the condition of, and shall continue to accept, the Must-Take Space in its presently existing, “as-is” condition, and hereby further acknowledges that neither Landlord
nor any agent of Landlord has made any representation or warranty regarding the condition of the Initial Premises, the Must-Take Space or the Building or with respect to the suitability of any of the foregoing for the conduct of Tenant’s
business. Landlord shall have no obligation to modify or improve any component in the Premises, the Base Building, or the Building systems or equipment in connection with the “Improvements” (as defined in Section 2.1 below).
The “Base Building” shall include the structural portions of the Building, and the public restrooms, elevators, exit stairwells and the systems and equipment located in the internal core of the Building on the floor or floors on
which the Premises is located. The “Base Building Plans” are the plans provided by Landlord to Tenant and its Architect and Engineers (as defined herein), covering the Base Building, which are delivered for the purposes of planning
and design of the Improvements.

defined in Section 4.2.1, nor shall Landlord be obligated to pay a total amount which exceeds the Improvement Allowance. Landlord shall not be obligated to disburse any monies from the Initial Premises Allowance for which a request has
not been made prior to December 31, 2012, and any unused portion of the Initial Premises Allowance remaining as of such date shall remain with Landlord and Tenant shall have no further right thereto. Landlord shall not be obligated to disburse
any monies from the Must-Take Space Allowance for which a request has not been made prior to December 31, 2015, and any unused portion of the Must-Take Space Allowance remaining as of such date shall remain with Landlord and Tenant shall have
no further right thereto. Further, to the extent there are any funds remaining in the Initial Premises Allowance, Landlord shall not be obligated to disburse such funds for application toward the cost of Improvements in the Must-Take Space; and,
likewise, to the extent there are any funds remaining or the Must-Take Space Allowance, Landlord shall not be obligated to disburse such funds for application toward the cost of Improvements in the Initial Premises, as the case may be. Except as
otherwise expressly provided hereinbelow, all references in this Work Letter to the “Improvement Allowance” shall mean either the Initial Improvement Allowance or the Must-Take Space Improvement Allowance, as applicable. 

2.2 Disbursement of the Improvement Allowance. 

2.2.1 Improvement Allowance Items. Except as otherwise set forth in this Work Letter, the Improvement Allowance shall be disbursed by
Landlord (each of which disbursements shall be made pursuant to Landlord’s disbursement process, including, without limitation, Landlord’s receipt of invoices for all costs and fees described herein) only for the following items and costs
(collectively the “Improvement Allowance Items”): 
 2.2.1.1 Payment of (i) the fees of the “Architect” and

 2.2.1.5 The cost of any changes in the Base
Building when such changes are required by the Construction Drawings, such cost to include all direct architectural and/or engineering fees and expenses incurred in connection therewith; 

2.2.1.6 The cost of any changes to the Construction Drawings or Improvements required by all applicable building codes (the
“Code”); 
 2.2.1.7 The cost of the “Coordination Fee,” as that term is defined in Section 4.2.2.1
of this Work Letter; 
 2.2.1.8 Sales and use taxes; and 

2.2.1.9 All other costs to be expended by Landlord in connection with the construction of the Improvements, including, but not limited to,
costs incurred by Landlord for overtime pay for Landlord’s employees and agents to enable Tenant to perform work related to the Improvements in areas outside the Premises after such employee’s or agent’s regular working hours.

applicable pro-rata portion of the “Over-Allowance Amount” (defined in Section 4.2.1 below) in accordance with the terms and conditions of Section 4.2.1 of this Tenant Work Letter). Tenant’s request for payment
shall be deemed Tenant’s acceptance and approval of the work furnished and/or the materials supplied as set forth in Tenant’s payment request. Thereafter, Landlord shall deliver a check to Tenant made payable to Contractor, to Tenant, or
to Contractor and Tenant jointly, as Tenant may request (provided that, if Tenant requests a check payable only to Tenant, then Landlord shall not be obligated to deliver such check unless and until Tenant has provided Landlord unconditional
mechanic’s lien releases from all of Tenant’s Agents in compliance with California Civil Code Section 3262(d)(2) or Section 3262(d)(4), as applicable) in payment of the lesser of: (A) the amounts so requested by Tenant, as

portion of the Improvement Allowance (not including the Final Retention) which shall be exclusive of the pro-rata portion of the Over-Allowance Amount to be paid by Tenant pursuant to the terms of Section 4.2.1 of this Tenant Work
Letter, provided that Landlord does not dispute any request for payment based on non-compliance of any work with the “Approved Working Drawings,” as that term is defined in Section 3.4 below, or due to any substandard work, or
for any other reason. Landlord’s payment of such amounts shall not be deemed Landlord’s approval or acceptance of the work furnished or materials supplied as set forth in Tenant’s payment request. 

2.2.2.2 Final Retention. Subject to the provisions of this Work Letter, and provided Tenant delivers sufficient evidence to Landlord
showing that the full amount of the Over-Allowance Amount has then been paid by Tenant, a check for the Final Retention payable to Contractor or Tenant, as Tenant may request, shall be delivered by Landlord to Tenant within thirty (30) days
following the completion of construction of the Improvements, provided that (i) Tenant delivers to Landlord (a) paid invoices for all Improvements and related costs for which the Improvement Allowance is to be dispersed, (b) signed
permits for all Improvements completed within the Premises, (c) properly executed unconditional mechanic’s lien releases in compliance with both California Civil Code Section 3262(d)(2) and either Section 3262(d)(3) or
Section 3262(d)(4) from Tenant’s contractor, subcontractors and material suppliers and any other party which has lien rights in connection with the construction of the Improvements (provided that, if Tenant requests a check payable only to
Tenant, then Landlord shall not be obligated to deliver such check unless and until Tenant has provided Landlord all unconditional mechanic’s lien releases in accordance with California Civil Code Section 3262(d)(4)), (ii) Landlord
has determined that no substandard work exists which adversely affects the mechanical, electrical, plumbing, heating, ventilating and air conditioning, life-safety or other systems of the Building, the curtain wall of the Building, the structure or
exterior appearance of the Building, or any other tenant’s use of such other tenant’s leased premises in the Building, (iii) Architect delivers to Landlord a certificate, in a form reasonably acceptable to Landlord, certifying that
the construction of the Improvements in the Premises has been substantially completed, (iv) Tenant

delivers to Landlord a “close-out package” in both paper and electronic forms (including, as-built drawings, and CADD files for the associated plans, warranties and guarantees from all
contractors, subcontractors and material suppliers, and an independent air balance report); and (v) a certificate of occupancy, a temporary certificate of occupancy or its equivalent is issued to Tenant for the Premises. 

2.2.2.3 Other Terms. Landlord shall only be obligated to make disbursements from the Improvement Allowance to the extent costs are
incurred by Tenant for Improvement Allowance Items. All Improvement Allowance Items for which the Improvement Allowance has been made available shall be deemed Landlord’s property under the terms of this Lease. 

2.3 Building Standards. Landlord has established specifications for certain Building standard components to be used in the construction
of the Improvements in the Premises and Tenant acknowledges it has received a copy of such specifications prior to execution of this Lease. The quality of Improvements shall be equal to or of greater quality than the quality of such Building
standards, provided that Landlord may, at Landlord’s option, require the Improvements to comply with certain Building standards. Landlord may make changes to said specifications for Building standards from time to time; provided, however,
Tenant shall not be required to comply with any such changes with respect to Improvements which have already been completed or for which Construction Drawings have already been approved by Landlord at the time of such changes. Removal requirements
regarding the Improvements are addressed in Article 8 of this Lease.

CONSTRUCTION DRAWINGS 

3.1 Selection of Architect/Construction Drawings. Tenant shall retain the architect/space planner selected by Tenant and reasonably
approved by Landlord (the “Architect”) to prepare the “Construction Drawings,” as that term is defined in this Section 3.1. Tenant shall retain the engineering consultants selected by Tenant and reasonably
approved 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 Premises, which work is not part
of the Base Building. 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 determined by Landlord, and shall be subject to Landlord’s approval rights as set forth in Sections 3.2 through 3.4 of this Work Letter. 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 Article 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,

Tenant’s delivery of such hard copies, Tenant shall send to Landlord via electronic mail one (1) .pdf electronic copy of such final space plan. 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 cause the Final
Space Plan to be revised to correct any deficiencies or other matters Landlord may reasonably require. Notwithstanding anything set forth herein to the contrary, Landlord shall not unreasonably withhold its approval of the Final Space Plan; provided
that Landlord and Tenant hereby agree that it shall be deemed reasonable for Landlord to withhold its approval of the Final Space Plan if a “Design Problem,” exists. A “Design Problem” shall mean and refer to any design
criteria which would (a) adversely affect the Building Structure or Building Systems; (b) be in non-compliance with Code or other Applicable Laws; (c) be seen from the exterior of the Premises; (d) cause material interference
with Landlord or other tenants of the Building, (e) not comply with the Building standards referenced in Section 2.3, above; or (f) affect the certificate of occupancy or its legal equivalent for the Building or any portion
thereof. 
 3.3 Final Working Drawings. After the Final Space Plan has been approved by Landlord, Tenant shall supply the Engineers
with a complete listing of standard and non-standard equipment and specifications, including, without limitation, B.T.U. calculations, electrical requirements and special electrical receptacle requirements for the Premises, to enable the Engineers
and the Architect to complete the “Final Working Drawings” (as that term is defined below) in the manner as set forth below. Upon the approval of the Final Space Plan by Landlord and Tenant, Tenant shall promptly cause the Architect and
the Engineers to complete the architectural and engineering drawings for the Premises, and Architect shall compile a fully coordinated set of architectural, structural, mechanical, electrical and plumbing working drawings in a form which is complete
to allow subcontractors to bid on the work and to obtain all applicable permits (collectively, the “Final Working Drawings”) and shall submit the same to Landlord for Landlord’s approval. Tenant shall supply Landlord with four
(4) hard copies signed by Tenant of the Final Working Drawings, and concurrently with Tenant’s delivery of such hard copies, Tenant shall send to Landlord via electronic mail one (1) .pdf electronic copy of such Final Working
Drawings. Landlord shall advise Tenant within seven (7) business days after Landlord’s receipt of the Final Working Drawings for the Premises if the same is unsatisfactory or incomplete in any respect. If Tenant is so advised, Tenant shall
immediately revise the Final Working Drawings in accordance with such review and any disapproval of Landlord in connection therewith. Notwithstanding anything set forth herein to the contrary, Landlord shall not unreasonably withhold its approval of
the Final Working Drawings; provided that Landlord and Tenant hereby agree that it shall be deemed reasonable for Landlord to withhold its approval

of the Final Working Drawings if a Design Problem exists or the Final Working Drawings are inconsistent with the Final Space Plan. In addition, if the Final Working Drawings or any amendment
thereof or supplement thereto shall require alterations in the Base Building (as contrasted with the Improvements), and if Landlord in its sole and exclusive discretion agrees to any such alterations, and notifies Tenant of the need and cost for
such alterations, then Tenant shall pay the cost of such required changes in advance upon receipt of notice thereof. Tenant shall pay the sum of (i) all actual, out-of-pocket, third-party direct architectural and/or engineering fees in
connection therewith, (ii) all actual out-of-pocket “hard” construction costs in connection therewith, and (iii) ten percent (10%) of such foregoing “hard” construction costs for Landlord’s servicing and
overhead relating to the actual construction of such required changes.

shall be approved by Landlord (the “Approved Working Drawings”) in accordance with Section 3.3 of this Work Letter prior to the commencement of construction of the Premises by Tenant. After approval by Landlord of the
Final Working Drawings, Tenant may submit the same to the appropriate municipal 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 may not be unreasonably withheld. 
 3.5 Electronic Approvals. Notwithstanding any provision to the contrary contained in the
Lease or this Work Letter, Landlord may, in Landlord’s sole and absolute discretion, transmit or otherwise deliver any of the approvals required under this Work Letter via electronic mail to Tenant’s representative identified in
Section 5.1 of this Work Letter, or by any of the other means identified in Section 29.16 of this Lease.

 4.2 Construction of Improvements by Tenant’s Agents. 

4.2.1 Construction Contract; Cost Budget. Tenant shall engage the Contractor under an AIA A101 Stipulated Sum Agreement (2007 Version)
accompanied by Landlord’s standard AIA A201 General Conditions (2007 Version) as modified by Landlord (collectively, the “Contract”). Prior to the commencement of the construction of the Improvements, and after Tenant has
accepted all bids for the Improvements, Tenant shall provide Landlord with a detailed breakdown, by trade, of the final costs to be incurred or which have been incurred, as set forth more particularly in Sections 2.2.1.1 through
2.2.1.9, above, in connection with the design and construction of the Improvements to be performed by or at the direction of Tenant or the Contractor, which costs form a basis for the amount of the Contract (the “Final
Costs”). As used herein, the “Over-Allowance Amount” shall be equal to the difference between the amount of the Final Costs and the amount of the Improvement Allowance (less any portion thereof already disbursed by
Landlord, or in the process of being disbursed by Landlord, on or before the commencement of construction of the Improvements). If an Over-Allowance Amount exists, then, Tenant shall pay Tenant’s pro-rata share of each amount requested by the
Contractor or otherwise to be disbursed under this Work Letter (which pro-rata share shall equal a fraction, the numerator of which shall equal the Over-Allowance Amount, and the denominator of which shall equal the Final Costs), and such payment by
Tenant (the “Over-Allowance Payments”) shall be a condition to Landlord’s obligation to pay any additional/future portions of the Improvement Allowance pursuant to the terms and conditions of Section 2.2, above. In
the event that, after the Final Costs have been delivered by Tenant to Landlord, the costs relating to the design and construction of the Improvements shall change, any additional costs necessary to such design and construction in excess of the
Final Costs, shall be added to the Over-Allowance Amount and to the Final Costs, and the Over-Allowance Payments shall be recalculated in accordance with the terms of the immediately preceding sentence. In connection with any payment of the
Over-Allowance Amount made by Tenant pursuant to this Section 4.2.1, Tenant shall provide Landlord with the documents described in Sections 2.2.2.1(0, (ii), (iii) and (iv) of this Work Letter, above,
for Landlord’s approval, prior to Tenant paying such costs. 
 4.2.2 Tenant’s Agents. 

4.2.2.1 Landlord’s General Conditions for Tenant’s Agents and Improvement Work. Tenant’s and Tenant’s Agent’s
construction of the Improvements shall comply with the following: (i) the Improvements shall be constructed in strict accordance with the Approved Working Drawings; (ii) Tenant’s Agents shall submit schedules of all work relating to
the Improvements to Contractor and Contractor shall, within five (5) business days of receipt thereof, inform Tenant’s Agents of any changes which are necessary thereto, and Tenant’s Agents shall adhere to such corrected schedule; and
(iii) Tenant shall abide by all rules made by Landlord’s Building manager with respect to the use of freight, loading dock and service elevators, storage of materials, coordination of work with the contractors of other tenants, and any
other matter in connection with this Work Letter, including, without limitation, the construction of the Improvements. Tenant shall pay a logistical coordination fee (the “Coordination Fee”) to Landlord in an amount equal to the
product of three percent (3%) and the sum of the 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
Improvements, which Coordination Fee shall be for services relating to the coordination of the construction of the Improvements.

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 Improvements and/or Tenant’s disapproval of all or any portion of any request for payment. Such indemnity by Tenant, as set forth in this 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 Improvements, and (ii) to enable Tenant to obtain any
building permit or certificate of occupancy for the Premises. 
 4.2.2.3 Requirements of Tenant’s Agents. Each of Tenant’s
Agents shall guarantee to Tenant and for the benefit of Landlord that the portion of the Improvements for which it is responsible shall be free from any defects in workmanship and materials for a period of not less than one (1) year from the
date of completion thereof. Each of Tenant’s Agents shall be responsible for the replacement or repair, without additional charge, of all work done or furnished in accordance with its contract that shall become defective within one
(1) year after the completion of the work performed by such contractor or subcontractors. The correction of such work shall include, without additional charge, all additional expenses and damages incurred in connection with such removal or
replacement of all or any part of the Improvements, and/or the Building and/or common areas that may be damaged or disturbed thereby. All such warranties or guarantees as to materials or workmanship of or with respect to the Improvements shall be
contained in the Contract or subcontract and shall be written such that such guarantees or warranties shall inure to the benefit of both Landlord and Tenant, as their respective interests may appear, and can be directly enforced by either. Tenant
covenants to give to Landlord any assignment or other assurances which may be necessary to effect such right of direct enforcement. 

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 this Lease.

insurance shall be in amounts and shall include such extended coverage endorsements as may be reasonably required by Landlord including, but not limited to, the requirement that all of Tenant’s Agents shall carry insurance in accordance with
the Contractor Insurance Requirements attached hereto as Exhibit B-l, and otherwise in form and with companies as are required to be carried by Tenant as set forth in this Lease.

 4.2.2.4.3 General Terms. Certificates for all insurance carried pursuant to this
Section 4.2.2.4 shall be delivered to Landlord before the commencement of construction of the Improvements and before the Contractor’s equipment is moved onto the site. All such policies of insurance must contain a provision that
the company writing said policy will give Landlord thirty (30) days prior written notice of any cancellation or lapse of the effective date or any reduction in the amounts of such insurance. In the event that the Improvements are damaged by any
cause during the course of the construction thereof, Tenant shall immediately repair the same at Tenant’s sole cost and expense. Tenant’s Agents shall maintain all of the foregoing insurance coverage in force until the Improvements are
fully completed and accepted by Landlord, except for any Products and Completed Operation Coverage insurance required by Landlord, which is to be maintained for ten (10) years following completion of the work and acceptance by Landlord and
Tenant. All policies carried under this Section 4.2.2.4 shall insure Landlord and Tenant, as their interests may appear, as well as Contractor and Tenant’s Agents. 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 requirements for the foregoing insurance shall not derogate from the provisions for indemnification of Landlord by Tenant under Section 4.2.2.2 of this Work Letter. 

4.2.3 Governmental Compliance. The Improvements shall comply in all respects with the following: (i) the Code and other state,
federal, city or quasi-governmental laws, codes, ordinances and regulations, as each may apply according to the rulings of the controlling public official, agent or other person; (ii) applicable standards of the American Insurance Association
(formerly, the National Board of Fire Underwriters) and the National Electrical Code; and (iii) building material manufacturer’s specifications. 

4.2.4 Inspection by Landlord. Landlord shall have the right to inspect the Improvements at all times, provided however, that
Landlord’s failure to inspect the Improvements shall in no event constitute a waiver of any of Landlord’s rights hereunder nor shall Landlord’s inspection of the Improvements constitute Landlord’s approval of the same. Should
Landlord disapprove any portion of the Improvements as a result of such Improvements not complying with the Approved Working Drawings or due to a defect in construction, 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 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 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 Improvements until such time as the defect,
deviation and/or matter is corrected to Landlord’s satisfaction.

 Kilroy Realty Corporation (KRC)- Contractor Insurance Requirements 

The following coverage is required for all contracts, but may be adjusted for size and complexity of project. Certificates of insurance and the applicable
endorsements must be received by KRC prior to entering the project or commencement of work. Such policies shall not be cancelled or modified, nor shall any of the coverages required herein be reduced, except after 30 days prior written
notice to KRC. 
 KRC requests that the Insurance Certificate and Endorsement documents be issued with blanket wording “ALL
LOCATIONS” if permitted by the carriers. If not available, the project site/building address must be included on certificate and endorsements. 
  

	*	Can be combined with Umbrella/Excess Liability policy to meet required limits. 

  

	I.	Commercial General Liability*: 

  

					
	 Combined limits shall not be less than the following:
	  			
	 General Aggregate limit on a Per Project Basis Endorsement

	 Personal and Advertising Injury
	  	$	1,000,000	  
	 Each Occurrence
	  	$	1,000,000	  
	 Fire Damage (any one fire)
	  	$	50,000	  
	 Medical Payments (any one person)
	  	$	5,000	  

 (a) Such insurance shall be on an Occurrence Basis (ISO form CG0001 or equivalent) with reasonably
acceptable deductibles. 
 (b) The policy shall include severability of interest and cross-liability (separation of named insured) 

(c) The policy shall include contractual liability equivalent to ISO form CG00010196.

(g) Policy shall name Kilroy Realty Corporation and/or any subsidiary, partnership, joint venture, corporation or affiliate now existing or
hereinafter formed or acquired as an additional insured using ISO form CG2010 11/85, or comparable form. Additional Insured forms limiting coverage to “ongoing operations” are unacceptable. 

(h) Contractor’s insurance shall be primary to any similar insurance maintained by Kilroy Realty Corporation and/or any subsidiary,
partnership, joint venture, corporation or affiliate now existing or hereinafter formed or acquired, whose insurance shall be considered excess and non-contributing with insurance maintained by Contractor. 

(i) Policy shall be endorsed to waive all rights of subrogation against Kilroy Realty Corporation and/or any subsidiary, partnership, joint
venture, corporation or affiliate now existing or hereinafter formed or acquired. 
 (j) Contractor shall continuously maintain coverage

MARKET RENT DETERMINATION FACTORS 

When determining Market Rent, the following rules and instructions shall be followed. 

1. RELEVANT FACTORS. The “Comparable Transactions” shall be the “Net Equivalent Lease Rates” per
rentable square foot, at which tenants, are, pursuant to transactions consummated within eighteen (18) months prior to the commencement of the Option Term, leasing non-sublease, non-encumbered space comparable in location and quality to the
Premises containing a square footage comparable to that of the Premises for a term of five (5) years, in an arm’s-length transaction, which comparable space is located in “Comparable Buildings.” The terms of the Comparable
Transactions shall be calculated as a “Net Equivalent Lease Rate” pursuant to the terms of this Exhibit H, and shall take into consideration only the following terms and concessions: (i) the rental rate and escalations for
the Comparable Transactions, (ii) the amount of parking rent per parking permit paid in the Comparable Transactions, if any, (iii) operating expense and tax protection granted in such Comparable Transactions such as a base year or expense
stop (although for each such Comparable Transaction the base rent shall be adjusted to a triple net base rent using reasonable estimates of operating expenses and taxes as determined by Landlord for each such Comparable Transaction);
(iv) rental abatement concessions, if any, being granted such tenants in connection with such comparable space, (v) any “Renewal Allowance,” as defined herein below, to be provided by Tenant in connection with the Option Term as
compared to the improvements or allowances provided or to be provided in the Comparable Transactions, taking into account the contributory value of the existing improvements in the Premises, such value to be based upon the age, design, quality of
finishes, and layout of the existing improvements, and (vi) all other monetary concessions (including the value of any signage), if any, being granted such tenants in connection with such Comparable Transactions. Notwithstanding any contrary
provision hereof, in determining the Market Rent, no consideration shall be given to any period of rental abatement, if any, granted to tenants in Comparable Transactions in connection with the design, permitting and construction of improvements, or
any commission paid or not paid in connection with such Comparable Transaction. The Market Rent shall include adjustment of the stated size of the Premises based upon the standards of measurement utilized in the Comparable Transactions; provided,
however, the size of the Premises shall, notwithstanding the foregoing, be at least equal to the greater of: (i) the square footages set forth in this Lease, and (ii) the square footage of the Premises determined pursuant to the standards of space
measurement used in the Comparable Transactions. 
 2. TENANT SECURITY. The terms of article 21 of the lease shall remain
applicable during the Option Terms. 
 3. RENEWAL IMPROVEMENT ALLOWANCE. Notwithstanding anything to the contrary set forth in
this Exhibit H, once the Market Rent for the Option Term is determined as a Net Equivalent Lease Rate, if, in connection with such determination, it is deemed that Tenant is entitled to an improvement or comparable allowance for the
improvement of the

	 	 KILROY REALTY

301 BRANNAN STREET
 [StumbleUpon,

Premises, (the total dollar value of such allowance shall be referred to herein as the “Renewal Allowance”), Landlord shall pay the Renewal Allowance to Tenant pursuant to a
commercially reasonable disbursement procedure determined by Landlord and the terms of Article 8 of this Lease, and, as set forth in Section 5, below, of this Exhibit H, the rental rate component of the Market Rent
shall be increased to be a rental rate which takes into consideration that Tenant will receive payment of such Renewal Allowance and, accordingly, such payment with interest shall be factored into the base rent component of the Market Rent. 

4. COMPARABLE BUILDINGS. For purposes of this Lease, the term “Comparable Buildings” shall mean (i) the
Building and other first-class institutionally-owned office buildings which are comparable to the Building in terms of age (based upon the date of completion of construction or major renovation as to the building containing the portion of the
Premises in question), quality of construction, level of services and amenities (including, but not limited to, the type (e.g., surface, covered, subterranean) and amount of parking), size and appearance, and are located in the “Comparable
Area,” which is the “South of Market District” submarket in San Francisco. 
 5. METHODOLOGY FOR REVIEWING AND
COMPARING THE COMPARABLE TRANSACTIONS. In order to analyze the Comparable Transactions based on the factors to be considered in calculating Market Rent, and given that the Comparable Transactions may vary in terms of length of term, rental
rate, concessions, etc., the following steps shall be taken into consideration to “adjust” the objective data from each of the Comparable Transactions. By taking this approach, a “Net Equivalent Lease Rate” for each of the
Comparable Transactions shall be determined using the following steps to adjust the Comparable Transactions, which will allow for an “apples to apples” comparison of the Comparable Transactions. 

5.1. The contractual rent payments for each of the Comparable Transactions should be arrayed monthly or annually over the lease term. All
Comparable Transactions should be adjusted to simulate a net rent structure, wherein the tenant is responsible for the payment of all property operating expenses in a manner consistent with this Lease. This results in the estimate of Net Equivalent
Rent received by each landlord for each Comparable Transaction being expressed as a periodic net rent payment. 
 5.2 Any free rent or
similar inducements received over time should be deducted in the time period in which they occur, resulting in the net cash flow arrayed over the lease term. 

5.3 The resultant net cash flow from the lease should be then discounted (using an 8% annual discount rate) to the lease commencement date,
resulting in a net present value estimate. 
 5.4 From the net present value, up front inducements (improvements allowances and other
concessions) and leasing commissions should be deducted. These items should be deducted directly, on a “dollar for dollar” basis, without discounting since they are typically incurred at lease commencement, while rent (which is discounted)
is a future receipt.

301 BRANNAN STREET
 [StumbleUpon,

 5.5 The net present value should then amortized back over the lease term as a level monthly or
annual net rent payment using the same annual discount rate of 8.0% used in the present value analysis. This calculation will result in a hypothetical level or even payment over the option period, termed the “Net Equivalent Lease Rate” (or
constant equivalent in general financial terms). 
 6. USE OF NET EQUIVALENT LEASE RATES FOR COMPARABLE TRANSACTIONS. The Net
Equivalent Lease Rates for the Comparable Transactions shall then be used to reconcile, in a manner usual and customary for a real estate appraisal process, to a conclusion of Market Rent which shall be stated as a “NNN” lease rate
applicable to each year of the Option Term.

 FIRST AMENDMENT TO OFFICE LEASE 

This FIRST AMENDMENT TO OFFICE LEASE (“First Amendment”) is made and entered into as of the 31st day of August, 2015, by and
between KILROY REALTY, L.P., a Delaware limited partnership (“Landlord”), and STUMBLEUPON, INC., a Delaware corporation (“Tenant”). 

R E C I T A L S : 

A. Landlord and Tenant entered into that certain Office Lease dated December 15, 2011 (the “Lease”), whereby Landlord
leased to Tenant and Tenant leased from Landlord 62,852 rentable square feet of space (the “Premises”), located on the entirety of the second (2nd), third (3rd), fourth (4th), fifth (5th) and sixth
(6th) floors of that certain building (the “Building”) located at 301 Brannan Street, San Francisco, California. 

B. On August 25, 2015, Landlord filed a complaint against Tenant for unlawful detainer on account of Tenant’s failure to pay rent,
which complaint was filed in the Superior Court of California, County of San Francisco (the “UD Litigation”). Tenant denies that Landlord is or was entitled to any relief pursuant to the UD Litigation. 

C. By this First Amendment, Landlord and Tenant desire to settle the UD Litigation without admission of liability, dismiss the UD Litigation
with prejudice, and modify the Lease as provided herein. 
 D. Pursuant to the terms of that certain Sublease Agreement dated as of
February, 2014 (the “Sublease”), by and between Tenant, as sublessor, and Okta, Inc., a Delaware corporation (“Subtenant”), as sublessee, Tenant agreed to sublease to Subtenant the portion of the Premises located on
the third (3rd), fourth (4th), and fifth (5th) floors of the Building, containing a
total of 37,815 rentable square feet (the “Sublet Premises”). Landlord consented to the terms of the Sublease pursuant to that certain Consent to Sublease Agreement dated as of March 31, 2014 (the “Consent to
Sublease”), by and among Landlord, Tenant, and Subtenant. The portion of the Premises located on the second (2nd) and sixth
(6th) floors of the Building, containing a total of 25,037 rentable square feet, is referred to herein as the “Retained Premises”. Concurrently herewith, Landlord, Tenant,
and Subtenant are entering into that certain First Amendment to the Consent to Sublease Agreement, dated as of an even date herewith (the “Consent to Sublease Amendment”), which includes additional provisions relating to
Tenant’s rent obligations and Landlord’s rights and remedies under the Lease (as hereby amended). The terms of the Consent to Sublease Amendment are hereby incorporated by reference into the Lease, and the Lease is amended thereby. 

E. The parties desire to amend the Lease on the terms and conditions set forth in this First Amendment. 

  
 - 4 - 

 A G R E E M E N T : 

NOW, THEREFORE, in consideration of the foregoing recitals and the mutual covenants contained herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows: 
 1.
Terms. All capitalized terms when used herein shall have the same respective meanings as are given such terms in the Lease unless expressly provided otherwise in this First Amendment. 

2. Effectiveness of Lease. In consideration of the covenants set forth herein to be performed by Tenant, subject to satisfaction
of the Conditions Precedent (as that term is defined hereinbelow), the Lease shall be amended as set forth herein, and, as amended, shall continue in full force and effect. Within one (1) business day following the full execution and delivery
of this First Amendment, and provided that (i) Landlord has timely received the Outstanding Rent Amount (as that term is defined in Section 3 below), (ii) Landlord has timely received the Prepaid Rent Amount (as that term is defined
in Section 4 below), (iii) the Consent to Sublease Amendment has been fully executed and delivered, and (iv) all of the Consent Specific Conditions Precedent (as that term is defined in the Consent to Sublease Amendment) have been
timely satisfied (collectively, the “Conditions Precedent”, and with items (i) through (iii) being referred to as the “Lease Specific Conditions Precedent”)), then Landlord shall file a request for
dismissal of the UD Litigation with prejudice. Notwithstanding any contrary provision of this First Amendment, the effectiveness of this First Amendment, and Landlord’s agreement to file a request for the dismissal of the UD Litigation pursuant
to the foregoing sentence, is conditioned upon the timely satisfaction of all of the Conditions Precedent. Landlord shall have no liability whatsoever to Tenant relating to or arising from the failure of any of the Conditions Precedent to be
satisfied. The Lease shall remain unmodified unless and until such time as all of the Conditions Precedent are timely satisfied. 
 3.
Outstanding Rent. Landlord and Tenant acknowledge and agree that as of the date of this First Amendment, Tenant owes Landlord, as past-due Rent under the Lease, the amount of Two Hundred Eighty-Six Thousand Eight Hundred Seventy-Nine and
77/100 Dollars ($286,879.77) (the “Outstanding Rent Amount”) for the month of August 2015. Concurrently with Tenant’s execution of this First Amendment, Tenant shall pay the Outstanding Rent Amount to Landlord. 

4. Prepaid Rent. Landlord and Tenant acknowledge and agree that the Base Rent and the estimate of Tenant’s Share of Direct
Expenses due and owing with respect to the Retained Premises for the months of September and October 2015 is equal to $207,332.46 in the aggregate (the “Prepaid Rent Amount”), which consists of $200,296.00 in Base Rent obligations
and $7,036.46 per month as the estimate of Tenant’s Share of Direct Expenses. Concurrently with Tenant’s execution of this First Amendment, Tenant shall pay the Prepaid Rent Amount to Landlord, and Landlord shall credit the amount of the
Prepaid Rent against Tenant’s Base Rent and Tenant’s Share of Direct Expenses obligations applicable to the Retained Premises for such period. 

5. Landlord Contraction Right. At any time, Landlord shall have the right to terminate Tenant’s lease of the portion of the
Retained Premises, consisting of a total of 12,548 rentable square feet located on the sixth (6th) floor of the Building (the “Contraction Space”),

  
 - 5 - 

 
effective as of the date (the “Contraction Date”) set forth in the Contraction Notice (as that term is defined hereinbelow), which Contraction Date shall be no earlier than
October 31, 2015 and shall be at least thirty (30) days following the date that Landlord provides Tenant written notice (the “Contraction Notice”) stating Landlord’s election to terminate Tenant’s lease of the
Contraction Space, pursuant to the terms of this Section 5 (and such Contraction Notice may be delivered to Tenant prior to October 31, 2015). Landlord shall not have the right to exercise the contraction right set forth in this
Section 5, if Landlord has previously granted its consent to a sublease of all or any portion of the Contraction Space; provided, however, upon request by Tenant for Landlord’s consent to a sublease, Landlord may, instead, deliver the
Contraction Notice. Upon the Contraction Date, (i) Tenant’s lease of the Contraction Space shall automatically terminate and be of no further force or effect, (ii) Landlord and Tenant shall be relieved of their respective obligations
with respect to the Contraction Space as of the Contraction Date, except those obligations which relate to the period up to and including the Contraction Date, including, without limitation, the payment by Tenant or Landlord of all amounts owed to
the other party with respect to the Contraction Space up to and including the Contraction Date, and (iii) Tenant’s Share shall be reduced by 16.8588% based on the rentable square footage of the Contraction Space. Tenant shall return the
Contraction Space to Landlord upon a termination thereof in accordance with the terms of the Lease (as amended) as if the Lease Term had expired with respect to the Contraction Space; provided, however, in no event shall Landlord be obligated to
reduce the L-C Amount (as that term is defined in Section 21.1 of the Lease, and amended by Section 9 below). 
 6. Consent
to Sublease Amendment; Transfer Premium. The Consent to Sublease Amendment, provides among other items, for the direct payment to Landlord by Subtenant of all rent due under the Sublease. The Consent to Sublease Amendment also includes

 OFFICE LEASE 

THIS LEASE, dated December 11, 2014 for purposes of reference only (the “Effective Date”), is made and entered into by
and between SIX THIRTY-FOUR SECOND STREET, LLC, a Delaware limited liability company (“Landlord”) and OKTA INC., a Delaware corporation (“Tenant”). 

1. The Premises. 
 1.1 Landlord hereby
leases to Tenant and Tenant hereby leases from Landlord, the Premises designated in the Summary of Basic Lease Information (“Summary”) attached hereto, and which is more particularly described and outlined on the floor plan attached
hereto and marked Exhibit A, all of which is incorporated herein by this reference. The Premises is located in the building at the address designated in the Summary (the “Building”), and located on the parcel of real property
(the “Site”) under the Building. Tenant acknowledges that Landlord has made no representation or warranty regarding the condition of the Premises, Building, or Site except as specifically stated in this Lease. The parties hereto
agree that said letting and hiring is upon and subject to the terms, covenants and conditions herein set forth and Tenant and Landlord covenant as a material part of the consideration for this Lease to keep and perform each and all of said terms,
covenants and conditions by it to be kept and performed, and this Lease is made upon the condition of such performance. 
 1.2 Tenant shall
have the nonexclusive right to use in common with other tenants in the Building, subject to the reasonable discretion of Landlord to determine the manner in which the public and common areas are maintained and operated, the loading and unloading
areas, roadways, sidewalks, walkways, parkways, and driveways appurtenant to the Building Premises (“Common Areas”). 

1.3 Landlord reserves the rights from time to time as set forth below provided that Landlord shall use commercially reasonable efforts with
respect to the exercise of any and all such rights so as not to interfere with Tenant’s use of or access to the Premises: 
 (a) To
remove, install, reinstall, use, maintain, repair and replace pipes, ducts, conduits, wires and appurtenant meters and equipment for service to other parts of the Building above the ceiling surfaces, below the floor surfaces, within the walls and in
the central core areas, and to relocate any pipes, ducts, conduits, wires and appurtenant meters and equipment included in the Premises which ‘are located in the Premises or located elsewhere outside the Premises, and to expand the Building;

 (b) To make changes to the Common Areas, including, without limitation, changes in the location, size, shape and number of driveways,
entrances, loading and unloading areas, ingress, egress, direction of traffic and walkways; 
 (c) To close temporarily any of the Common
Areas for maintenance purposes so long as reasonable access to the Premises remains available; 

 (d) To use the Common Areas at any time, including, but not limited to, while engaged in making
additional improvements, repairs or alterations to the Building, or any portion thereof; and/or 
 (e) To do and perform such other acts and
make such other changes in, to or with respect to the Site, Common Areas and Building including, without limitation, the roof and windows of the Building as Landlord may, in the exercise of Landlord’s reasonable business judgment, deem to be
appropriate. 
 Except in the case of emergency, Landlord will use reasonable efforts to perform any work described in this Paragraph 1.3
which might be disruptive only on weekends or during periods after business hours to the extent reasonably practicable (the cost of any and all such work including, without limitation, overtime costs incurred by Landlord in connection therewith may
be included in Common Operating Expenses, subject to the limitations set forth in Article 6 below). To the extent that Landlord installs, maintains, uses, repairs or replaces pipes, cables, ductwork, conduits, utility lines, and/or wires through
hung ceiling space, exterior perimeter walls and column space, adjacent to and in demising partitions and columns, in or beneath the floor slab or above, below, or through the Premises, then in the course of making any such installation or repair:
(x) Landlord will not reduce Tenant’s usable space, except to a de minimus extent, if the same are not installed behind existing walls or ceilings; and (y) Landlord shall box in any of the same installed adjacent to existing walls
with construction materials substantially similar to those existing in the affected area(s) of the Premises. 
 1.4 Tenant acknowledges that
certain furniture, fixtures and equipment owned by Landlord may be located within the Premises, and that the Premises currently contains certain data communication cabling within the wall and ceiling. All of such personal property and cabling owned
by Landlord shall remain at the Premises and Tenant shall have the right to use all of the same during the, Term. Tenant shall have access to available space in the riser closet and shall be responsible for taking service to the floors occupied by
Tenant. Tenant may install additional cabling and conduits at its sole cost and expense subject to Landlord’s reasonable prior approval as provided herein. Upon expiration or earlier termination of the Term, Tenant shall return all of the
original personal property to Landlord in good condition and repair, subject to normal wear and tear and casualty. On or about the Early Access Date, Landlord and Tenant shall jointly conduct an inspection of the existing personal property located
within the Premises, so as to create an inventory of such personal property and the condition of such personal property, in order to establish “baseline” for determining the appropriate condition of such property upon return to Landlord.

 1.5 The rights and obligations of the parties regarding the tenant improvements, alterations or construction of the Premises to be
performed at the commencement of the Term are described in the Tenant Work Letter (“Work Letter”) attached to this Lease as Exhibit B. Any inconsistency between the provisions of the Work Letter and the provisions of the
balance of this Lease shall be governed by the provisions of the Work Letter. 
 1.6 References in this Lease to “rentable square
feet”, “rentable square footage” and “rentable area” shall have the same meanings, and Tenant hereby acknowledges and agrees that the rentable square footage of the Premises shall be deemed, and is, 45,032 rentable square
feet, 

  
 4 

 
and the rentable square footage of the Building shall be deemed, and is, 46,752 rentable square feet. Landlord represents that the foregoing square footage determinations were the result of a
measurement made of the Building and the Premises in accordance with BOMA Standard (i.e., the American National Standard method of measuring floor area in office buildings of the Building Owners and Managers Association (ANSI Z65.1 -2010)). The
parties agree that the 45,032 rentable square foot measurement of the Premises and the 46,752 rentable square foot measurement of the Building shall not be changed, and no adjustment in the Monthly Basic Rent, any monetary or other obligation of
Tenant, or any other term of this Lease shall be made by reason of a change in the rentable square footage of the Premises or the Building except in connection with a physical change in the size of the Premises (and, in the event of any such
physical change in the size of the Premises, any remeasurement necessitated thereby shall be carried in accordance with the BOMA Standard). 
 2.
Term. 
 2.1 The term of this Lease (“Term”) shall be for the period designated in the Summary. The Term shall
commence on the Lease Commencement Date and end on the Lease Expiration Date, unless the Term shall be sooner terminated or extended as hereinafter provided. 

2.2 Tenant shall have one option (the “Extension Option”) to extend the Term, for an additional five (5) year period
(the “Extended Term”) on all the terms and conditions contained in this Lease with the exception of the Monthly Basic Rent which shall be adjusted pursuant to the provisions of Paragraphs 4.2 and with the further exception that upon
exercise of the Extension Option by Tenant, Tenant shall thereafter have no further right to extend the Term. In order to exercise the Extension Option, Tenant shall deliver written notice of its exercise of the option (“Option
Notice”) to Landlord no earlier than eighteen (18) months and no later than twelve (12) months prior to the expiration of the initial Term. The Extension Option shall be subject to the following terms and conditions:

delivery of the Option Notice and the commencement date of the Extended Term, Tenant is not in default under this Lease beyond applicable notice and cure periods (hereinafter “Default”). 

(b) The rights contained in this Paragraph shall be personal to the originally named Tenant and may be exercised only by the originally named
Tenant (or an entity which controls, is controlled by or is under common control with Tenant, or to any entity resulting from the merger or consolidation with Tenant or to any person or entity which acquires substantially all of the assets of Tenant
as a going concern) and only if the originally named Tenant (or an entity which controls, is controlled by or is under common control with Tenant, or to any entity resulting from the merger or consolidation with Tenant or to any person or entity
which acquires substantially all of the assets of Tenant as a going concern) occupies at least the entire area on two adjacent floors of the Premises as of the date it exercises the Extension Option in accordance with the terms of this Paragraph.

 (c) If Tenant properly exercises the Extension Option and is not in Default, at the end of the initial Term, the Term shall be extended
for the applicable Extended Term, References in this Lease to the “Term” shall include the initial Term of nine (9) years, and shall, in addition, include the Extended Term, if applicable.

 3. Early Access and Possession. Landlord shall give Tenant written notice of the date on which the
Premises shall be available for the purposes as described in this Paragraph 3 (“Early Access Date”). It is anticipated that the Early Access Date shall occur on or about June 1, 2015. Landlord shall allow Tenant, and
Tenant’s contractors, vendors and service providers, access to the Premises and the Building at any time on or after the Early Access Date for the purpose of constructing the Tenant Improvements pursuant to the Work Letter and installing
Tenant’s furniture, fixtures, equipment and other personal property, and to prepare the Premises for Tenant’s occupancy. Tenant shall provide Landlord with reasonable written evidence of liability insurance pursuant to Paragraph 21.1(a)
prior to Tenant’s entry onto the Premises pursuant to the provisions of this Paragraph 3. Landlord shall have no liability or responsibility for any damage to Tenant’s property stored or kept on the Premises, whether prior or subsequent to
the Lease Commencement Date except to the extent attributable to the negligence or willful misconduct of Landlord, Landlord’s employees, agents, representatives or contractors (and, in any event, subject to the provisions of Paragraph 21.6
below). 
 4. Monthly Basic Rent/Rent Increases. 

4.1 Tenant agrees to pay to Landlord, on a monthly basis, the Monthly Basic Rent designated in the Summary commencing on the Lease
Commencement Date (subject to abatement as set forth in Paragraph 4.4 below). Commencing on the first anniversary of the Lease Commencement Date and continuing on each anniversary of the Lease Commencement Date thereafter, the Monthly Basic Rent
shall increase by an amount equal to three percent (3%) of the Monthly Basic Rent payable for the month immediately preceding the applicable anniversary date as more particularly provided in the Summary. Tenant shall pay the Monthly Basic Rent
in advance on the first day of each and every calendar month during said Term, except that the Monthly Basic Rent due for the first month of the Term shall be paid upon the execution hereof. In the event that the Lease Commencement Date occurs other
than on the first day of a calendar month, (i) Monthly Basic Rent for the initial partial calendar month of the Lease Term shall be prorated in the proportion that the number of days this Lease is in effect during such calendar month bears to
the actual number of days in the first month of the Term, and the prepaid first month’s Monthly Basic Rent shall be applied to such prorated amount with the balance of the prepaid first month’s Monthly Basic Rent being applied to reduce
the payment of Monthly Basic Rent to be paid on the first day of the first full calendar month of the Term of this Lease, and (ii) the Monthly Basic Rent payable for any calendar month in which the amount of Monthly Basic Rent is to increase as
provided in the Summary shall be determined by prorating the applicable lesser and greater Monthly Basic Rent based on the portion of the calendar month for which each is applicable with the sum of such prorated amounts being the Monthly Basic Rent
for such calendar Month. Upon the determination of the Lease Commencement Date, the parties shall promptly enter into a Lease Commencement Agreement in the form of Exhibit C attached hereto, setting forth the Lease Commencement Date and
a schedule of the Monthly Basic Rent payable hereunder in accordance with the provisions of this Paragraph 4.1. The Monthly Basic Rent and all additional rent including, without limitation, Operating Rent, shall be paid to Landlord without any
prior demand therefor and without any deduction or offset whatsoever, except as expressly provided herein, in lawful money of the 

  
 6 

 
United States of America, which shall be legal tender at the time of payment, at the address of Landlord designated in the Summary or to such other person or at such other place as Landlord may
from time to time designate in writing delivered at least thirty (30) days prior to the date upon which such alternative address is to become effective. For purposes of this Lease, any amount due to Landlord from Tenant, including without
limitation Monthly Basic Rent, Direct Operating Expenses and Common Operating Expenses shall be considered additional rent for purposes of this Lease and the word “rent” in this Lease shall include such additional rent as well as
Monthly Basic Rent, Direct Operating Expenses and Common Operating Expenses unless the context specifically or clearly implies that only the Monthly Basic Rent, Direct Operating Expenses or Common Operating Expenses is referenced. 

4.2 In the event Tenant exercises its Extension Option pursuant to the provisions of Paragraph 2.2, the Monthly Basic Rent shall be adjusted
at the commencement of the Extended Term to reflect 100% of the “then-Fair Market Rental Value of the Premises” pursuant to the terms of this Paragraph. Landlord shall notify Tenant of Landlord’s good faith estimation of the Fair
Market Rental Value in writing within thirty (30) days of receipt of the Option Notice (“Landlord’s Estimate”), setting forth in Landlord’s Estimate any Comparable Transactions (defined below) upon which
Landlord’s Estimate is based. If Tenant does not agree with Landlord’s Estimate, Tenant shall deliver written notice of Tenant’s objection to Landlord within thirty (30) days of receipt of Landlord’s Estimate, failing which
Landlord’s Estimate shall be deemed to be final. If Tenant timely objects to Landlord’s Estimate, Landlord and Tenant shall diligently attempt in good faith to agree on the Fair Market Rental Value of the Premises on or before the
thirtieth (30th) day following delivery of Tenant’s written objection to Landlord’s Estimate (the “Outside Agreement Date”). If Landlord and Tenant are unable to agree on the new Monthly Basic Rent by the
Outside Agreement Date, the Fair Market Rental Value of the Premises shall be determined by real estate brokers pursuant to this Paragraph. The parties shall each select a broker within thirty (30) days of the Outside Agreement Date, who
together shall attempt to determine the Fair Market Rental Value of the Premises. If either party fails to appoint a broker within such time period, the broker timely appointed by the other party shall be the sole broker, whose determination shall
be binding on both parties. If two brokers are timely appointed, but they are unable to agree on the Fair Market Rental Value of the Premises within sixty (60) days of the Outside Agreement Date, they shall mutually select a third broker. In
the event that the two brokers are unable to mutually select a third broker, within sixty (60) days of the Outside Agreement Date, either Landlord or Tenant shall be entitled to apply to the Superior Court in and for the County of San Francisco
for appointment of a third broker in accordance with the procedures as established by such court. Upon the selection of the third broker, each of Landlord’s broker and Tenant’s broker shall place their final good faith determination of the
Fair Market Rental Value of the Premises in an envelope and deliver same to the third broker as well as the other broker (each, a “Final Determination”). The third broker shall, within twenty (20) days of his/her
selection following the delivery of the Final Determinations, choose one of the first two brokers’ Final Determination as the applicable Fair Market Rental Value based on which of the two (2) it believes to be closest to its own
determination. The third broker shall have no option but to select one or the other of the first two brokers’ Final Determinations, and shall not have the power to propose a different Fair Market Rental Value. If either broker fails to deliver
a Final Determination, then the Final Determination delivered by the other broker shall be deemed to be the Fair Market Rental Value. Each party shall bear the cost of their respective brokers; if a third broker is necessary, the parties shall share
equally the cost of the third broker. 

  
 7 

 
All brokers shall be licensed as such by the State of California, and shall have a minimum of ten (10) years’ experience in the leasing of similar properties in the San Francisco South
of Market District (“Comparable Buildings”). Comparable Buildings shall include, without limitation, 123 Townsend Street and 139 Townsend Street, San Francisco, California. As used herein, the “South of Market
District” shall mean the area bordered by the following streets: King, Folsom, 4th Street and the Embarcadero. The Fair Market Rental Value shall mean the economic terms at which tenants, as of the first day of the applicable Extended Term,
are leasing for a comparable term, space comparable to the Premises, from a willing landlord, at arm’s length, which comparable space is located in Comparable Buildings with similar amenities (“Comparable Transactions”),
or, if such Comparable Buildings, or comparable space within Comparable Buildings, is not available, adjustments shall be made in the determination of Fair Market Rental Value to reflect the age and quality of the Building and Premises as contrasted
to other buildings used for comparison purposes, taking into consideration location, views, quality and nature of improvements, proposed term of the lease, extent of services to be provided, the time that the particular rate under consideration
became or is to become effective, as well as all tenant concessions and inducements, the standard of measurement by which the rentable area of each space is measured and parking availability, which shall (i) not be subleased, and
(ii) shall be leased for a term comparable to the subject Extended Term, upon terms comparable to those contained in this Lease other than Monthly Basic Rent. The intent of the parties is that Tenant will obtain the same rent and other economic
benefits that landlords would otherwise give in Comparable Transactions and that Landlord will make and receive the same economic payments and concessions that landlords would otherwise make and receive in Comparable Transactions. The Monthly Basic
Rent shall be adjusted to reflect the Fair Market Rental Value, as so determined. The brokers shall expressly consider in their determination of Fair Market Rental Value of the Premises the date on which the Extended Term is to commence,
acknowledging that the date on which the determination is made may be several months prior to the date on which the Extended Term commences, The determination of Fair Market Rental Value shall also include the determination of annual increases in
the Monthly Basic Rent throughout the Extended Term, to the extent that such increases are typically being applied in the leases of comparable properties used in determining the Fair Market Rental Value. 

4.3 All payments received by Landlord from Tenant shall be applied to the oldest payment obligation owed by Tenant to Landlord. No designation
by Tenant either in a separate writing or in a check or money order, shall modify this clause or have any force or effect. 
 4.4 Provided
that Tenant is not in Default, then during the first four (4) months of the Term (the “Rent Abatement Period”), Tenant shall not be obligated to pay the Monthly Basic Rent otherwise attributable to the Premises during such Rent
Abatement Period (the “Rent Abatement”). The Rent Abatement Period shall commence as of the Lease Commencement Date. Landlord and Tenant acknowledge that the aggregate amount of the Rent Abatement equals Eight Hundred Forty
Thousand Five Hundred Ninety-Seven Dollars and Thirty-Two Cents ($840,597.32). Tenant acknowledges and agrees that the foregoing Rent Abatement has been granted to Tenant as additional consideration for entering into this Lease, and for agreeing to
pay the rent and performing the terms and conditions otherwise required under this Lease. If at any time Tenant shall be in Default under this Lease, and if this Lease is terminated by Landlord as a consequence of such Default, then Landlord may
include in its claim for termination damages, the unamortized (as of the date of the Default) amount of the Rent 

  
 8 

 
Abatement (assuming amortization of the Rent Abatement on a straight-line basis over the Term). Notwithstanding the above provisions of this Paragraph 4.4, Tenant shall be obligated to pay to
Landlord the initial installment of Monthly Basic Rent prior to the Early Access Date, which initial installment of Monthly Basic Rent shall be applied after expiration of the Rent Abatement Period consistent with the provisions of Paragraph 4.1
above. 
 5. Payment of Direct Operating Expenses. Commencing as the Lease Commencement Date Tenant shall pay directly or reimburse
Landlord for the costs and expenses (“Direct Operating Expenses”) set forth below in this Paragraph 5. Costs to be reimbursed to Landlord as more particularly provided in Paragraphs 5.2 and 5.3 below shall be reimbursed in
accordance with the provisions of Paragraphs 6.2 and 6.3 below in a manner consistent with the reimbursement to Landlord of Tenant’s Share of Common Operating Expenses. 

5.1 Tenant shall pay prior to delinquency all taxes assessed against and levied upon Tenant owned leasehold improvements, trade fixtures,
furnishings, equipment and all personal property of Tenant contained in the Premises or elsewhere. When possible, Tenant shall cause its leasehold improvements other than the Tenant Improvements, trade fixtures, furnishings, equipment and all other
personal property to be assessed and billed separately from the real property of Landlord. 
 5.2 Tenant shall reimburse Landlord for the
cost of all Base Building Services and services as otherwise provided by Landlord pursuant to provisions of Paragraph 18 as more particularly provided in such Paragraph, 

5.3 Tenant shall reimburse Landlord for Landlord’s costs in connection with matters benefitting the Premises but not-the Retail Space
including, without limitation, maintenance and repair of the elevator and the HVAC systems serving the Premises. The exclusions set forth below in Paragraph 6.2 shall also be deemed exclusions to the expenses payable by Tenant pursuant to the
provisions of this Paragraph 5.3, and the limitation on the inclusion of capital expenses set forth below in Paragraph 6 shall similarly apply to Tenant’s obligations to reimburse Landlord for capital items pursuant to the provisions of this
Paragraph 5.3. 
 6. Payment of Taxes, Common Operating Expenses and Other Charges. 

6.1 Landlord shall pay prior to delinquency all Real Property Taxes (as defined below) which accrue in connection with the Building beginning
on the Commencement Date and continuing thereafter throughout the Term of this Lease, and Tenant shall reimburse Landlord for Tenant’s Share of all Real Property Taxes paid by Landlord relating to the Premises within thirty (30) days of
receipt of Landlord’s invoice therefor and evidence of payment. If any installment of Real Property Taxes paid by Landlord covers any period of time prior to the Lease Commencement Date or after expiration of the Term, Tenant’s Share of
the Real Property Taxes shall be equitably prorated to cover only the period of time on and after the Lease Commencement Date that this Lease is in effect, and Landlord shall reimburse Tenant for any overpayment by reason of such proration. If
Landlord receives a refund of Real Property Taxes, attributable to any period during the Term, Landlord shall, either pay to Tenant, or credit against subsequent payments of Common Operating Expenses due hereunder, an amount equal to Tenant’s
Share of the refund, net of any reasonable expenses incurred by Landlord in achieving 

  
 9 

 
such refund; provided, however, if this Lease shall have expired or is otherwise terminated, Landlord shall refund in cash any such refund or credit due to Tenant within thirty (30) days
after Landlord’s receipt of such refund. Landlord’s obligation to so refund to Tenant any such refund of Real Property Taxes shall survive such expiration or termination. 

As used herein, the term “Real Property Taxes” shall include any form of real estate tax, any tax levied on the collection of
rent payable under this Lease (whether in the form of a business tax or rental income tax), any general, special, ordinary or extraordinary assessment, any improvement bond, levy or similar tax (or any other fee, charge, or excise which may be
imposed as a substitute for any of the foregoing) imposed upon the Building by any authority having the direct or indirect power to tax, including any city, county, state or federal government, or any school, agricultural, sanitary, fire, street,
drainage or other improvement district, levied against any legal or equitable interest of Landlord in the Premises. Real Property Taxes shall not include (i) any estate, inheritance, transfer, gift, state or federal income or franchise taxes,
or (ii) any penalties or interest accrued in connection with the Real Property Taxes (unless the result of Tenant’s failure to comply with its obligations under this Lease) or (iii) any taxes directly payable by any occupant of the
Building (including Tenant) pursuant to the provisions of such occupant’s lease or other occupancy agreement. Tenant acknowledges that Tenant shall be responsible for the payment of any increase in Real Property Taxes during the Term resulting
from construction of the Tenant Improvements or any subsequent improvements constructed by Tenant during the Term. To the extent any Real Property Taxes may permit the payment in installments (such as a special assessment), Landlord shall elect to
cause the same to be paid in the maximum allowable number of installments, and Tenant shall only be responsible for paying those installments to the extent accruing during the Term of the Lease. 

Tenant shall be entitled to contest any Real Property Taxes for which Tenant is responsible provided that Tenant shall obtain Landlord’s
consent (which consent shall not be unreasonably withheld, conditioned or delayed) prior to contesting any Real Property Taxes, and in the event of such tax contest by Tenant, Tenant shall (i) fully indemnify Landlord pursuant to the provisions
of this Lease, for any loss or liability incurred by Landlord as a consequence of Tenant’s contest of Real Property Taxes (provided, however, that such indemnity obligation shall not include the obligation to compensate Landlord on the basis of
any claim that Tenant’s challenge or appeal of Real Property Taxes should have resulted in a reduction in Real Property Taxes that is greater than the reduction (if any) in Real Property Taxes realized as a consequence of Tenant’s
challenge of Real Property Taxes and (ii) bear the full cost of any such contest including without limitation the cost of any interest and penalties which may be assessed. If a change in Real Property Taxes is obtained for any year of the Term,
then Real Property Taxes for that year shall be retroactively adjusted to reflect any actual reduction realized by Landlord and Landlord shall provide Tenant with a credit, if any, based on the actual adjustment. Landlord shall notify Tenant in
writing of any material change in any tax assessment or reassessment of the Building and the Site within sufficient time to allow Tenant to review (and protest or appeal, if appropriate) such assessment or reassessment. Landlord shall cooperate at
no more than a nominal cost to Landlord and in good faith with Tenant in connection with any protest or contest of taxes or assessments made by Tenant.

 6.2 Tenant shall pay to Landlord Tenant’s Share (as defined in the Summary) of all expenses
incurred by Landlord in the operation of the Building, excluding any expenses paid directly by any tenant of the Building including, without limitation, the Direct Operating Expenses payable by Tenant (the “Common Operating
Expenses”), pursuant to this Paragraph, Common Operating Expenses are intended to be inclusive of all costs of operating and maintaining the Building and the real property on which it is situated exclusive only of the Direct Operating
Expenses, subject to the exclusions and limitations set forth herein. Landlord agrees to make reasonable efforts to minimize costs insofar as such efforts are not inconsistent with Landlord’s intent to operate and maintain the Building in a
first class manner. At Tenant’s request, Landlord and Tenant shall meet and confer on an annual basis to review Landlord’s anticipated Common Operating Expenses (and any projects or programs included therein) over the ensuing calendar
year. Common Operating Expenses may include, but shall not be limited to, the following: all costs and expenses of repairing, operating and maintaining the heating, ventilating and air conditioning (“HVAC”) system for the Building,
the elevators, and all other major systems and components of the Building other than costs constituting Direct Operating Expenses, including maintenance contracts therefore; costs and expenses incurred by Landlord in providing water and sewer
service to the Building, and other utilities and services not directly paid for by Tenant as a portion of the Direct Operating Expenses or otherwise or payable by any other Building occupant; costs incurred by Landlord for accountants and other
professionals reasonably necessary in making the computations required hereunder; all costs and expenses incurred by Landlord in operating, managing, maintaining and repairing the Building including without limitation, all sums expended in
connection with the general maintenance and repair of the Building, window washing, maintenance and repair of stairways, Building signs, the Building Systems (defined below), planting and landscaping (if any), costs of supplies and personnel to
implement such services, rental and/or depreciation of machinery and equipment used in providing maintenance and other services, fire protection services, and trash removal services and a reasonable management fee payable to Landlord (such property
management fee shall not exceed four percent (4.0%) of all Gross Revenues; “Gross Revenues” shall mean the aggregate of the annual rentals and other revenue of any kind whatsoever derived from the use or occupancy of the
Building, accrued or collected with respect to the Building, excluding only any management fee chargeable to Tenant in the calculation of the Common Operating Expenses (so as to prevent Landlord, Landlord’s affiliate, or the Building’s
management company from earning a management fee on the management fee). Landlord may cause any or all of said services to be provided by an independent contractor or contractors, or the Building management company, provided that any salary, wage or
other similar charges or expenses payable by Landlord shall not be included in the Common Operating Expenses other than (i) direct labor costs incurred by Landlord to perform maintenance and repairs and other services at the Building, and
(ii) a portion of the salary of a building manager/superintendent to the extent the same is dedicated to the Building and the cost thereof is passed through to Landlord by Landlord’s building management company. Common Operating Expenses
may also include all costs of (i) capital improvements, repairs, alterations or replacements made to the Building or any Building System carried out in order to conform to changes subsequent to the Effective Date in any applicable laws,
ordinances, rules, regulations or orders of any governmental or quasi-governmental authority having jurisdiction over the Building or (ii) any capital improvements or replacement carried out for the purpose of improving the performance or
efficiency of any Building System (referred to herein as “Permitted Capital Expenditures”). Permitted Capital 

  
 11 

 
Expenditures shall be amortized (including interest at a rate of eight percent (8%) per annum) over the useful life of such capital improvement, repair, alteration or replacement, as
reasonably determined in accordance with generally accepted accounting principles consistently applied (“GAAP”). Costs and expenses incurred by Landlord in operating, managing and maintaining the Building which are incurred
exclusively for the benefit of a specific tenant of the Building will not be included in the Common Operating Expenses. 
 Notwithstanding anything to the
contrary contained in this Lease, the following shall not be included within Common Operating Expenses: (i) leasing commissions, attorneys’ fees, costs, disbursements, and other expenses incurred in connection with negotiations or disputes
with tenants, or in connection with leasing, renovating, or improving space for tenants or other occupants or prospective tenants or other occupants of the Building; (ii) the cost of any service sold to any tenant (including Tenant) or other
occupant for which Landlord is entitled to be reimbursed as an additional charge or rental over and above the basic rent and escalations payable under the lease with that tenant including, without limitation, the Direct Operating Expenses payable by
Tenant pursuant to this Lease; (iii) depreciation other than depreciation on exterior window coverings provided by Landlord and carpeting in public corridors and common areas and the personal property referred to above; (iv) expenses in
connection with services or other benefits of a type that are not provided to Tenant but which are provided another tenant or occupant of the Building; (v) overhead profit increments paid to Landlord’s subsidiaries or affiliates for
management or other services on or to the Building or for supplies or other materials to the extent that the cost of the services, supplies, or materials exceeds the cost that would have been paid had the services, supplies, or materials been
provided by unaffiliated parties on a competitive basis; (vi) all interest, loan fees, and other carrying costs related to any mortgage or deed of trust or related to any capital item, and all rental and other payable due under any ground or
underlying lease, or any lease for any equipment ordinarily considered to be of a capital nature (except janitorial equipment which is not affixed to the Building); (vii) any compensation paid to clerks, attendants, or other persons in
commercial concessions operated by Landlord; (viii) advertising and promotional expenditures; (ix) costs of repairs and other work occasioned by fire, windstorm, or other casualty of an insurable nature; (x) any costs, fines, or
penalties incurred due to violations by Landlord of any governmental rule or authority, this Lease or any other lease in the Building, or due to Landlord’s negligence or willful misconduct; (xi) the cost of correcting any building code or
other violations which were violations prior to the Lease Commencement Date; (xii) the cost of containing, removing, or otherwise remediating any contamination of the Building (including the underlying land and ground water) by any toxic or
Hazardous Materials (defined in Paragraph 8.2(b)) where such contamination was not caused by Tenant; (xiii) costs for sculpture, paintings, or other objects of art (and insurance thereon or extraordinary security in connection therewith); and
(xiv) wages, salaries, or other compensation paid to any executive employees above the grade of building manager; any other expense that under generally prevailing property management practices within the South of Market District would not be
considered a normal maintenance or operating expense which is properly passed through to tenants. Additionally, any deductible payment under any Landlord’s policy of earthquake insurance shall be included in Common Operating Expenses and, for
the purpose of such inclusion shall be treated as a Permitted Capital Expenditure with a useful life of ten (10) years 

  
 12 

 On or before the first day of each partial or full calendar year during the Term, or as soon as practicable
thereafter, Landlord shall give to Tenant written notice of Landlord’s estimate of the Direct Operating Expenses and Tenant’s Share of Common Operating Expenses payable by Tenant pursuant to Paragraphs 5 and this Paragraph 6.2,
respectively for such calendar year or partial calendar year, as the case may be, which estimate shall be in form comparable to a Landlord’s Statement (defined below) and include a line-item breakdown of component costs. On or before the first
day of each month during each calendar year or partial calendar year, as the case may be, Tenant shall pay to Landlord one-twelfth (l/12th) (or the applicable pro rata portion for any partial calendar year based on the number of months constituting
such partial calendar year) of the estimated Direct Operating Expenses and Tenant’s Share of Common Operating Expenses; provided, however, that if Landlord’s notice is not given prior to the first day of any calendar year, Tenant shall
continue to pay the Direct Operating Expenses and Common Operating Expenses on the basis of the prior year’s estimate until the month after Landlord’s notice is given. At any time and from time to time during the Term, Landlord may furnish
Tenant with written notice of a re-estimation of the annual Direct Operating Expenses and/or Tenant’s Share of Common Operating Expenses to reflect more accurately, in Landlord’s reasonable opinion, the then-current Direct Operating
Expenses and/or Common Operating Expenses. Commencing on the first day of the calendar month which commences at least thirty (30) days following the date of Landlord’s delivery of such notice to Tenant, and continuing on the first day of
each subsequent calendar month during the applicable calendar year (until subsequently re-estimated), Tenant shall pay to Landlord one-twelfth of the Tenant’s Share of the estimated annual Common Operating Expenses, as re-estimated as well as
one-twelfth (l/12th) of the estimated annual Direct Operating Expenses as re-estimated. 

6.3 After the expiration of each calendar year during the Term hereof Landlord shall furnish to Tenant an itemized statement, certified as
correct by Landlord, setting forth the total Direct Operating Expenses and Common Operating Expenses for the preceding calendar year, the amount of Tenant’s Share of Common Operating Expenses and the payments made by Tenant with respect to such
calendar year (“Landlord’s Statement”). Such annual statement shall be set forth in reasonable detail both the Direct Operating Expenses and Tenant’s Share of Common Operating Expenses. 

(a) a line-item breakdown showing at least the following major categories and subcategories of costs: 

(i) maintenance and repairs (cleaning; security; elevators; supplies; waste removal; heating, ventilation and air conditioning); 

(ii) landscaping; 
 (iii)
utilities (electricity; gas; and water and sewer); 
 (iv) insurance; 

(v) salaries (engineering; and administrative); and 

(vi) general and administrative (management fees; professional services; office supplies; and other). 

  
 13 

 If Tenant’s Share of the actual Common Operating Expenses and/or the actual Direct Operating
Expenses for such year as set forth in Landlord’s Statement exceeds the payment so made by Tenant, Tenant shall pay Landlord the deficiency within thirty (30) days after receipt of such statement. If the payments so made by Tenant exceed
Tenant’s Share of the actual Common Operating Expenses and/or the actual Direct Operating Expenses, Tenant shall be entitled to offset the excess against the next payment(s) due to Landlord because of Direct Operating Expenses and/or Common
Operating Expenses, or to receive from Landlord cash in such amount, within thirty (30) days if this Lease has terminated. Until Tenant receives Landlord’s Statement pursuant to this Paragraph setting forth a new amount of Tenant’s
estimated Tenant’s Share of Common Operating Expenses and the Direct Operating Expenses for the new calendar year, Tenant shall continue to pay such Tenant’s Share of the Common Operating Expenses and the Direct Operating Expenses at the
rate being paid for the year just completed. Landlord shall maintain at all times during the Term, at the office of Landlord’s property manager in San Francisco, California, full, complete and accurate books of account and records prepared in
accordance with generally accepted accounting principles with respect to Common Operating Expenses, Real Property Taxes and Direct Operating Expenses, and shall retain such books and records, as well as contracts, bills, vouchers, and checks, and
such other documents as are reasonably necessary to properly audit Common Operating Expenses, Real Property Taxes and Direct Operating Expenses. Within one hundred twenty (120) days after receipt of Landlord’s Statement, Tenant shall have
the right to audit at the offices of Landlord’s property manager located in San Francisco, at Tenant’s expense, Landlord’s accounts and records relating to Common Operating Expenses, Real Property Taxes and Direct Operating Expenses.
Such audit shall be conducted by an employee of Tenant or by a certified public accountant approved by Landlord, which approval shall not be unreasonably withheld. In no event shall Tenant use an auditing service that performs operating expense
audits on a “contingency” or “percentage savings” basis. If the final determination reveals that Landlord has overcharged Tenant, the amount overcharged shall be credited against Tenant’s next Common Operating Expenses and
Direct Operating Expense payment obligations, or paid in cash within thirty days, if the Lease has terminated. In the event the audit reveals Tenant has underpaid its portion of Common Operating Expenses and/or Direct Operating Expenses, Tenant
shall remit the shortfall to Landlord within thirty (30) days. Additionally, if Landlord is determined to have overcharged Tenant for Operating Expenses, Real Property Taxes and Direct Operating Expenses by five percent (5%) or more,
Landlord shall reimburse Tenant within thirty (30) days following such determination for the reasonable cost of Tenant’s review of Landlord’s books and records (which cost may not be included as a Common Operating Expense).
Notwithstanding the foregoing, Tenant shall not be responsible for any Common Operating Expenses attributable to any year which is first billed to Tenant more than two (2) calendar years after the date of expiration of the year to which such
Common Operating Expense applies, provided that Tenant shall nonetheless be responsible for any such sums for any year if the same are first levied by any governmental authority or by any public utility companies following the date that is two
(2) calendar years following the expiration of such year. 
 6.4 Tenant acknowledges that Landlord intends to obtain a LEED-EB
certification for the Building (Leadership in Energy and Environmental Design - Existing Building), and that the cost of obtaining such certification will be amortized over the useful life of such systems calculated in accordance with GAAP, and the
monthly amortized cost thereof (including an annual interest rate factor of eight percent (8%)) shall be included as a part of Common 

  
 14 

 
Operating Expenses payable by Tenant. Tenant also agrees to reasonably cooperate with Landlord to obtain and maintain the LEED-EB certification, including without limitation complying with
Landlord’s rules and regulations regarding recycling, use of “green” cleaning products and the like, as the same may be required in connection with the LEED-EB program. For purposes of this Paragraph 6.4 and the cost of obtaining
LEED-EB certification, such costs included in Common Operating Expenses shall not include (i) the cost of replacement of the air handler and chiller on the roof of the Building, (ii) the cost of replacing the roof of the Building,
(iii) the cost of replacing the elevator for the Building, or (iv) the cost for which Landlord is responsible pursuant to the Work Letter relating to compliance with Title 24 of the California Code of Regulations, all of which costs are
anticipated to be incurred by Landlord prior to the Lease Commencement Date. Notwithstanding any provision to the countrary of this Paragraph 6.4 in no event shall the aggregate amount payable by Tenant pursuant to the provisions of this Paragraph
6.4 during the initial term of nine (9) years exceed Two Hundred Thousand Dollars ($200,000). 
 7. Security Deposit. As and for security for
Tenant’s full and faithful performance of all the terms, covenants and conditions of this Lease to be kept and performed by Tenant, Tenant, upon execution of this Lease, shall deposit with Landlord a security deposit of Two Million Seven
Hundred Seventy-Three Thousand Two Hundred Eighty Seven Dollars ($2,773,287) in cash or, at Tenant’s option, in the form of an unconditional, irrevocable letter of credit (“LOC”) in such amount in favor of Landlord in a form
and from a financial institution located in San Francisco, California (or alternatively accepting presentations for draw purposes by facsimile and/or overnight courier), reasonably acceptable to Landlord. Landlord hereby approves Silicon Valley Bank
as the bank issuing the LOC. At any time during the Term upon at least ten (10) business days’ prior notice to Landlord, Tenant may elect to convert the form of the Security Deposit from cash to a LOC or from a LOC to cash, so long as the
provisions of this Paragraph 7 are complied with. If at any time during the Term, any item constituting rent as provided herein, or any other sum payable by Tenant to Landlord hereunder, shall be overdue and unpaid beyond any applicable notice and
cure periods, then Landlord may, at the sole option of Landlord, but without any requirement to do so, and without prejudice to any other remedy which Landlord may have, access the cash deposit, or draw down or make a claim or demand for draw
against the LOC, in the amount of the sum equal to the overdue and unpaid amount, together with Landlord’s actual and reasonable expenses incurred in connection with the Default, and apply such sum to payment of such overdue rent or other sum.
The LOC shall provide for partial draws and further provide that any draw thereunder shall be accompanied by a certificate of an officer or manager of Landlord stating that Tenant is in Default and that Landlord or its authorized agent is entitled
to draw down on the LOC the amount requested pursuant to the terms of this Lease. Further in the event of the failure of Tenant to keep and perform any nonmonetary term, covenant or condition of this Lease to be kept or performed by Tenant beyond
any applicable cure periods and the receipt of any required notice, at the sole option of Landlord, and without prejudice to any other remedy which Landlord may have, Landlord may access the cash deposit or draw down the entire LOC, or so much
thereof as may be necessary to compensate Landlord for any loss or damage sustained or suffered by Landlord, or which Landlord may sustain or suffer, due to such breach on the part of Tenant. In the event that all or any portion of the cash deposit
is accessed or the LOC is drawn down by Landlord to pay overdue rent or other sums due and payable to Landlord by Tenant hereunder as described in this Paragraph 7, then Tenant shall, within ten (10) business days after receipt of written
demand of Landlord, deliver 

  
 15 

 
to Landlord a sufficient amount in an additional LOC (or cash, as the case may be) to restore Landlord’s security to the original, total amount of the security deposit as provided in this
Paragraph. Any failure on the part of Tenant to do so within ten (10) business days following the date on which written demand for restoration is deemed given hereunder, shall constitute a Default of this Lease pursuant to Paragraph 25.1(d)
below without further written notice to Tenant. The LOC shall be maintained by Tenant during the entire Term of this Lease and for a period of thirty (30) days thereafter (the last day of such thirty (30) day period shall be referred to as
the “Return Date”). If the LOC is to expire before the Return Date, Tenant shall replace the LOC by providing Landlord with a substitute LOC at least thirty (30) days prior to the expiration date of the then effective
LOC being held by Landlord in the applicable amount required hereunder and the failure to do so shall constitute a Default entitling Landlord to draw the full amount of the LOC and hold the proceeds thereof as a cash security deposit hereunder. The
LOC shall provide, in part, that the LOC shall be automatically renewed through and including at least the Return Date unless the issuer gives written notice to Landlord at least thirty (30) days prior to the expiration of the LOC that such
issuer does not intend to renew the LOC. In such event, Landlord shall be entitled to draw the full amount of the LOC and hold the proceeds thereof as a cash security deposit hereunder unless a substitute LOC is delivered by Tenant to Landlord at
least twenty (20) days prior to the expiration of the then existing LOC. Any cash deposit held by Landlord as security shall be non-interest bearing and may be commingled by Landlord with other funds of Landlord. In the event Landlord transfers
the security deposit to any successor in interest of Landlord to title of the Site and Building, then, in such event, Landlord shall be discharged from any further obligation or liability with respect to the security deposit. Any LOC issued in favor
of Landlord may, if required by any lender holding a mortgage or deed of trust secured by the Site and Building, be transferred to such lender provided that such lender, Landlord and Tenant enter into an agreement reasonably acceptable to all
parties governing such lender’s right to draw down money on, or further transfer, the LOC. Tenant waives the provisions of California Civil Code Section 1950.7 and all other provisions of law now in force or that become in force after the
date of execution of this Lease that provide that Landlord may claim from a security deposit only those sums reasonably necessary to remedy defaults in the payment of rent, to repair damages caused by Tenant, or to clean the Premises. Landlord and
Tenant agree that Landlord may, in addition, claim those sums reasonably necessary to compensate Landlord for any loss or damage caused by the act or omission by Tenant or Tenant’s officers, agents, employees, independent contractors or
invitees as elsewhere provided herein. Upon the expiration or earlier termination of this Lease, Landlord shall return to Tenant within thirty (30) days of Tenant vacating the Premises so much of the security deposit as has not been applied or
entitled to be held by Landlord to be applied to cure any and all defaults by Tenant and/or to compensate Landlord for any and all damages or loss suffered or which may be suffered by Landlord resulting from the default or breach by Tenant. 

8. Use. 
 8.1 Tenant shall use the
Premises for general office purposes, including administrative functions, and all purposes reasonably incident thereto and reasonably commensurate with the operation and occupancy of a technology company headquarters in the South of Market District,
and shall not use or permit the Premises to be used for any other purpose without the prior written consent of Landlord, which consent may be granted or withheld in Landlord’s sole discretion. Subject to Landlord’s prior written approval
of plans 

  
 16 

 
therefore, Tenant shall have the right to use a portion of the Premises for the operation of, and include in the Tenant Improvements (or subsequent Changes) the construction of, a kitchen/cooking
facility (including a gas line of adequate capacity with gas lines stubbed to the Premises) for Tenant’s employees and guests only (in no event shall such kitchen/cooking facility be open to or serve the general public), on and subject to the
following terms and conditions: Tenant shall be responsible, at its sole cost and expense (subject to the application of the Tenant Improvement Allowance), for obtaining all applicable permits, licenses and governmental approvals necessary for the
use of the Premises for such kitchen/cooking facility uses (including, without limitation, any necessary approvals from the applicable health and/or fire departments, permits required in connection with any venting or other air-removal/circulation
system, and any required fire-suppression systems), copies of which shall be delivered to Landlord prior to Tenant’s installation of any alterations in the Premises in connection with such kitchen/cooking facility uses. Tenant shall have access
to the Premises 24 hours per day/ 365 days per year. Tenant shall not use or occupy the Premises in violation of any recorded covenants, conditions and restrictions affecting the Site or of any law, code, regulation, rule, order, or injunction or of
the Certificate of Occupancy issued for the Building. Upon five (5) business days written notice from Landlord, Tenant shall discontinue any specific use of the Premises which is declared by any governmental authority having jurisdiction to be
a violation of any recorded covenants, conditions and restrictions affecting the Site or of any law, code, regulation, rule, order, or injunction or of the Certificate of Occupancy. However, Tenant, at Tenant’s expense, may contest by
appropriate proceedings in good faith the legality or applicability of any law affecting the Premises, provided that (i) the Building or any part thereof (including the Premises) shall not be subject to being condemned or vacated by reason of
noncompliance or otherwise by reason of such contest, (ii) no unsafe or hazardous condition remains unremedied as a result of such contest, (iii) such non-compliance or contest is not prohibited under any then-applicable mortgage,
(iv) such non-compliance or contest shall not prevent Landlord from obtaining any and all permits and licenses then required by applicable laws in connection with the operation of the Building, and (v) the Certificate of Occupancy for the
Building (or any portion) is neither subject to being suspended by reason such of non-compliance or contest (any such proceedings instituted by Tenant being referred to herein as a “Compliance Challenge”). In the event that
Tenant commences a Compliance Challenge, Tenant’s obligation to cease any use specified in Landlord’s notice and/or obligation to comply with the applicable law in question shall, unless otherwise mandated by applicable law, be suspended
pending the resolution of the Compliance Challenge. Tenant shall not install any radio or television antenna, loudspeaker or other device on the roof or exterior walls of the Building without Landlord’s prior written consent. Landlord shall not
unreasonably withhold, delay or condition Landlord’s consent to Tenant’s installation of antennae on the roof of the Building. Subject to Tenant’s right to commence a Compliance Challenge, Tenant shall comply with any direction of any
governmental authority having jurisdiction which shall, by reason of the nature of Tenant’s specific use or alteration of the Premises, impose any duty upon Tenant or Landlord with respect to the Premises or with respect to the use or
occupation thereof. Tenant shall not do or permit to be done anything which will invalidate or increase the cost of any fire, extended coverage or any other insurance policy covering the Site, the Building, the Premises, and/or property located
therein and shall comply with all rules, orders, regulations and requirements of the Pacific Fire Rating Bureau or any other organization performing a similar function. Upon demand, Tenant shall promptly reimburse Landlord as additional rent for any
additional premium charged for 

  
 17 

 
such policy by reason of Tenant’s failure to comply with the provisions of this Paragraph 8. Tenant shall not do or permit anything to be done in or about the Site, the Building, and/or the
Premises which will unreasonably obstruct or interfere with the rights of other tenants or occupants of the Building, or injure them, or use or allow the Premises to be used for any unlawful purpose. Tenant shall not cause, maintain or permit any
nuisance in, on or about the Site, the Building and/or the Premises, or allow any noxious odors to exist at or emanate from the Site, the Building and/or the Premises. Tenant shall not commit or suffer to be committed any waste in or upon the Site,
the Building and/or the Premises and shall keep the Premises in good repair and appearance. Tenant shall not place a load upon the Premises which exceeds the average pounds of live load per square foot of floor area specified for the Building by
Landlord’s architect Huntsman Architectural Group, with the partitions to be considered a part of the live load. Landlord reserves the right to reasonably prescribe the weight and position of all safes, files and heavy equipment which Tenant
desires to place in the Premises so as to distribute properly the weight thereof, based upon Landlord’s architect’s written recommendation, which Landlord will provide to Tenant. Tenant’s business machines and mechanical equipment
which cause vibration or noise that may be transmitted to the Building structure or to any other space in the Building shall be so installed, maintained and used by Tenant as to eliminate such vibration or noise. Tenant shall be responsible for all
structural engineering required to determine structural load. Tenant shall fasten all files, bookcases and like furnishings to walls in a manner to prevent tipping over in the event of earth movements. Landlord shall not be responsible for any
damage or liability for such events. 
 8.2 Except for the normal and proper use and storage of typical cleaning fluids and solutions, and
office equipment supplies (such as copier toner), in amounts commensurate with Tenant’s permitted use and occupancy of the Premises, Tenant shall not use, introduce to the Site, the Building and/or the Premises, generate, manufacture, produce,
store, release, discharge or dispose of, on, under or about the Site, the Building and/or the Premises or transport to or from the Site, the Building and/or the Premises any Hazardous Material (as defined below in this Paragraph 8.2) or allow its
employees, agents, contractors, invitees or any other person or entity to do so. Tenant warrants that it shall not make any use of the Site, the Building and/or the Premises which may cause contamination of the soil, the subsoil or ground water.
Tenant shall not permit the Premises to be in violation of any laws regarding Hazardous Materials brought onto the Premises by Tenant, its employees, agents or contractors; provided however that nothing in this Lease shall be construed to impose
responsibility on Tenant for the remediation of Hazardous Materials that (i) were present in, on or under the Building on the Lease Commencement Date, (ii) are introduced into the Premises by Landlord’ its employees, agents or
contractors, or (iii) which may migrate to the Premises through the air, water or soil through no fault of Tenant, its employees, agents or contractors. Tenant shall give immediate written notice to Landlord of (i) any action, proceeding
or inquiry by any governmental authority or any third party with respect to the presence of any Hazardous Material on the Site, the Building and/or the Premises or the migration thereof from or to other property or (ii) any spill, release or
discharge of Hazardous Materials that occurs with respect to the Site, the Building and/or the Premises or Tenant’s operations, of which Tenant has notice. Landlord shall give immediate written notice to Tenant of (i) any action,
proceeding or inquiry by any governmental authority or any third party with respect to the presence of any Hazardous Material on the Site, the Building and/or the Premises or the migration thereof from or to other property or (ii) any spill,
release or discharge of Hazardous Materials that occurs with respect to the Site, the Building and/or the Premises or Landlord’s operations, of which Landlord has notice. 

  
 18 

 (a) Tenant shall indemnify and hold harmless Landlord, its directors, officers, members,
employees, managers, agents, successors and assigns (collectively “Landlord Parties”, individually a “Landlord Party”) from and against any and all claims arising from Tenant’s use, generation, manufacture,
production, storage, release, discharge or disposal of Hazardous Materials on the Site, the Building and/or the Premises in violation of the terms, covenants and conditions of this Paragraph 8. The indemnity shall include all costs, fines,
penalties, judgments, losses, attorney’s fees, expenses and liabilities incurred by any of the Landlord Parties for any such claim or any action or proceeding brought thereon including, without limitation,’ (a) all actual damages; and
(b) the costs of any cleanup, detoxification or other ameliorative work of any kind or nature required by any governmental agency having jurisdiction thereof, including without limitation all costs of monitoring and all fees and expenses of
consultants and experts retained by and of the Landlord Parties. This indemnity shall survive the expiration or termination of this Lease. In any action or proceeding brought against any of the Landlord Parties by reason of any such claim, upon
notice from such Landlord Party if such Landlord Party does not elect to retain separate counsel, Tenant shall defend the same at Tenant’s expense by counsel reasonably satisfactory to such Landlord Party. Landlord shall indemnify and hold
harmless Tenant, its directors, officers, members, employees, agents, successors and assigns (collectively “Tenant Parties”, individually a “Tenant Party”) from and against any and all claims arising from the use,
generation, manufacture, production, storage, release, discharge or disposal of Hazardous Materials on the Site, the Building and/or the Premises occurring prior to the Lease Commencement Date or during the Lease Term as a result of Landlord’s
or Landlord Parties’ use, generation, manufacture, production, storage, release, discharge or disposal of Hazardous Materials on the Site, the Building and/or the Premises. 

(b) As used herein, the term “Hazardous Material” shall mean any substance or material which has been determined by any
state, federal or local governmental authority to be capable of posing a risk of injury to health, safety or property, including all of those materials and substances designated as hazardous or toxic by the city or state in which the Premises are
located, the U.S. Environmental Protection Agency, the Consumer Product Safety Commission, the Food and Drug Administration, the California Water Resources Control Board, the Regional Water Quality Control Board, San Francisco Bay Region, the
California Air Resources Board, CAL/OSHA Standards Board, Division of Occupational Safety and Health, the California Department of Food and Agriculture, the California Department of Health Services, and any federal agencies that have overlapping
jurisdiction with such California agencies, or any other governmental agency now or hereafter authorized to regulate materials and substances in the environment. Without limiting the generality of the foregoing, the term “Hazardous
Material” shall include all of those materials and substances defined as “hazardous materials” or “hazardous waste” in Sections 66680 through 66685 of Title 22 of the California Administrative Code, Division 4, Chapter 30,
as the same shall be amended from time to time, petroleum, petroleum-related substances and the by-products, fractions, constituents and sub-constituents of petroleum or petroleum-related substances, asbestos, and any other materials requiring
remediation now or in the future under federal, state or local statutes, ordinances, regulations or policies. 

  
 19 

 9. Payments and Notices. All rents and other sums payable by Tenant to Landlord hereunder shall be paid to
Landlord by check, cashier’s check, ACH bank account transfer or wire transfer at the address designated by Landlord in the Summary or at such other places as Landlord may hereafter designate in writing at least thirty (30) days prior to
the effective date upon which payments are to be made to such alternate address. Any notice required or permitted to be given hereunder must be in writing and may be given by personal delivery, certified mail, return receipt requested, or by
recognized overnight courier. If notice is given by personal delivery, such notice shall be deemed to be given upon delivery (unless the date of delivery is a weekend or holiday, in which event such notice shall be deemed given upon the next
succeeding business day). If notice is given by certified mail addressed to Tenant or to Landlord at the address designated in the Summary, then such notice shall be deemed given three (3) business days following deposit in the U.S. Mail,
postage prepaid, addressed to Tenant or to Landlord at the addresses designated in the Summary. If notice is given by overnight courier, notice shall be deemed given the next business day following delivery to the courier for next business day
delivery, charges prepaid, addressed as stated above. Either party may by written notice to the other specify a different address for notice purposes except that Landlord may in any event use the Premises as Tenant’s address for notice
purposes. If more than one person or entity constitutes the “Tenant” under this Lease, the giving of any notice upon any one of said persons or entities shall be deemed as giving notice to all of said persons or entities. 

10. Brokers. The parties recognize that the brokers who negotiated this Lease are the brokers whose names are stated in the Summary, and agree
that Landlord shall be solely responsible for the payment of brokerage commissions to said brokers. Tenant shall have no responsibility therefor. As part of the consideration for the granting of this Lease, Tenant represents and warrants to Landlord
that no other broker, agent or finder was hired by Tenant, negotiated with Tenant or, to Tenant’s knowledge, was instrumental in negotiating or consummating this Lease and to Tenant’s knowledge there is no other real estate broker, agent
or finder who is, or might be, entitled to a commission or compensation in connection with this Lease. Any broker, agent or finder of Tenant whom Tenant has failed to disclose herein shall be paid by Tenant. Tenant shall hold Landlord (and/or each
of the Landlord Parties) harmless from all damages and indemnify Landlord (and/or each of the Landlord Parties) for all said damages paid or incurred by Landlord (and/or each of the Landlord Parties) resulting from any claims that may be asserted
against Landlord (and/or each of the Landlord Parties) by any broker, agent or finder who has, or has claimed to have, rendered services to Tenant undisclosed by Tenant herein. Landlord shall hold Tenant harmless from all damages and indemnify
Tenant for all said damages paid or incurred by Tenant resulting from any claims that may be asserted against Tenant by any broker, agent or finder who has, or has claimed to have, rendered services to Landlord undisclosed by Landlord herein. 

11. Holding Over. If Tenant remains in possession of the Premises after expiration or earlier termination of this Lease with Landlord’s
express consent, Tenant’s occupancy shall be a month to month tenancy at a rent agreed upon by Landlord and Tenant but, in no event less than the Monthly Basic Rent payable under this Lease during the last full month before the date of
expiration or earlier termination. The month to month tenancy shall be on the terms and conditions of this Lease except as provided in the preceding sentence and the Lease clauses concerning extension rights. If Tenant holds over after the
expiration or earlier termination of the Term hereof without the express written consent of Landlord, Tenant shall become a tenant at 

  
 20 

 
sufferance only, at a rental rate equal to one hundred fifty percent (150%) of the Monthly Basic Rent which would be applicable to the Premises upon the date of expiration of the Term
(prorated on a daily basis), and otherwise subject to the terms, covenants and conditions herein specified, so far as applicable including, without limitation, the obligation to pay Direct Operating Expenses and Common Operating Expenses as provided
in Paragraphs 5 and 6.2. Acceptance by Landlord of rent after such expiration or earlier termination shall not constitute a consent to a holdover hereunder or result in a renewal. The foregoing provisions of this Paragraph 11 are in addition to and
do not affect Landlord’s right of re-entry or any rights of Landlord hereunder or as otherwise provided by law. If Tenant fails to surrender the Premises, Tenant shall indemnify and hold Landlord harmless from all loss or liability arising out
of such failure, including without limitation, any claim made by any succeeding tenant founded on or resulting from such failure to surrender. No provision of this Paragraph 11 shall be construed as implied consent by Landlord to any holding over by
Tenant. Landlord expressly reserves the right to require Tenant to surrender possession of the Premises to Landlord as provided in this Lease upon expiration or other termination of this Lease. The provisions of this Paragraph 11 shall not be
considered to limit or constitute a waiver of any other rights or remedies of Landlord provided in this Lease or at law; provided, however, that Landlord shall not be entitled to consequential damages except as expressly provided in this Paragraph
11. 
 12. Taxes on Tenant’s Property. Tenant shall be liable for and shall pay before delinquency, taxes levied against any personal
property or trade fixtures placed by Tenant in or about the Premises. If any such taxes on Tenant’s personal property or trade fixtures are levied against Landlord or Landlord’s property, or if the assessed value of the Site, the Building,
and/or the Premises is increased by the inclusion therein of a value placed upon such personal property or trade fixtures of Tenant, and if Landlord, after ten (10) business days’ prior written notice to Tenant, pays the taxes based upon
such increased assessments, which Landlord shall have the right to do regardless of the validity thereof, but only under proper protest if requested by Tenant, then, upon demand Tenant shall repay to Landlord the taxes levied against Landlord, or
the proportion of such taxes resulting from such increase in the assessment. Notwithstanding the foregoing, at Tenant’s sole cost and expense and at no expense or cost to Landlord, Tenant shall have the right, in the name of Landlord and with
Landlord’s full cooperation, to bring a good faith suit in any court of competent jurisdiction to recover the amount of any such taxes so paid under protest, any amount so recovered to belong to Tenant. For avoidance of doubt, Real Property
Taxes will not include any taxes payable by Tenant pursuant to the provisions of this Paragraph 12, or any taxes payable by any other building occupant pursuant to provisions similar to this Paragraph 12. 

13. Condition of Premises. 
 13.1 Other
than as expressly stated in this Lease, Tenant acknowledges that neither Landlord nor any of the Landlord Parties have made any representation or warranty of any kind whatsoever with respect to the Site, the Premises and/or the Building or with
respect to the suitability of either for the conduct of Tenant’s business. Tenant acknowledges and agrees that Tenant is relying solely upon Tenant’s own inspection of the Site, the Building and the Premises, and Tenant is not relying on
any representation or warranty from the Landlord regarding the Site, the Premises or the Building, except as specifically set forth in this Lease, including, without limitation, any representation or warranty as to the physical condition, design or
layout of the 

  
 21 

 
Site, the Building and the Premises. Notwithstanding the foregoing, Landlord expressly represents and warrants that all Building Systems serving the Premises are, or will be as of the Lease
Commencement Date, in good working condition and the Premises and Building as delivered by Landlord to Tenant (and after completion by Tenant of the Compliance Work as defined in the Work Letter) shall comply with all applicable laws and
regulations, including, without limitation the Americans With Disabilities Act (42 U.S.C. Section 12101 et seq.) (“ADA”), and all applicable codes relating to restroom facilities and Landlord at Landlord’s sole cost and
expense, will be responsible for all work and costs incurred (whether in connection with Tenant’s construction of the Tenant Improvements pursuant to the Work Letter or otherwise) to bring the Premises, into compliance with the ADA or Title 24
as enacted and in effect as of the Lease Commencement Date. Subject to the provisions of the Work Letter, the costs incurred by Tenant to bring any portion of the Premises into compliance with any such laws in connection with Tenant’s
construction of Tenant Improvements, shall be the responsibility of Landlord and Landlord shall reimburse Tenant for any such costs within thirty (30) days following Tenant’s delivery to Landlord of a reasonably detailed invoice therefor
provided that the obligation of Landlord to reimburse Tenant shall be as more particularly governed by the provisions of the Work Letter. Common Area Operating Expenses will not include any costs incurred by Landlord to bring the Building, or any
portion thereof, into compliance with any of the laws or regulations described in the immediately preceding sentence applicable to the Building. 

13.2 Landlord hereby<discloses to Tenant pursuant to California Civil Code Sections 55.53 and 1938 that as of the date of this Lease, the
Premises and the Building have not been inspected by a Certified Access Specialist. 
 14. Alterations. 

14.1 Other than changes to the roof, the structural portions of the Building and/or structural portions of the Premises, and to the
foundation, Tenant may, at any time and from time to time during the Term of this Lease, at its sole cost and expense, make alterations, additions, installations, substitutions, improvements and decorations (hereinafter collectively called
“Changes” and individually, a “Change”) in and to the Premises, on the following conditions, provided that such Changes will not result in a violation of applicable laws, codes, regulations, orders or injunctions or
require a change in the Certificate of Occupancy applicable to the Premises: 
 (a) The outside appearance, character or use of the Building
shall not be affected, and no Changes shall weaken or impair the structural strength or, in the reasonable opinion of Landlord, materially lessen the value of the Building, the Site, and/or the Premises or create the potential for unusual expenses
to be incurred upon the removal of Changes and the restoration of the Premises upon the termination of this Lease. 
 (b) No part of the
Building outside of the Premises shall be physically affected (other than tie-ins to Building Systems pursuant to approved plans), 
 (c)
The proper functioning of any of the mechanical, electrical, sanitary and other service systems or installations of the Building (“Service Facilities”) shall not be adversely affected, and there shall be no construction which might
interfere with Landlord’s free access to the Service Facilities or interfere with the moving of Landlord’s equipment to or from the enclosures containing the Service Facilities. 

  
 22 

 (d) In performing the work involved in making such Changes, Tenant shall be bound by and observe
all of the conditions and covenants contained in this Paragraph 14, and Tenant shall not unreasonably interfere with or unreasonably disturb any other tenants (of such tenants, invitees, employees, or agents) use and enjoyment of the Site and the
Building. 
 (e) All work shall be done at such times and in such manner as Landlord from time to time may reasonably designate. 

(f) Tenant shall not be permitted to install and make part of the Premises any materials, fixtures or articles which are subject to liens,
conditional sales contracts or chattel mortgages. 
 (g) Landlord shall have the right, to be exercised by written notice delivered to
Tenant concurrently with Landlord’s approval of any Change, to notify Tenant that the Change in question (or a component thereof) shall be required to be removed by Tenant upon date of expiration or sooner termination of this Lease. In such
event, Tenant will restore the Premises to their condition prior to the making of the applicable Changes, reasonable wear and tear, and damage for which Tenant is not liable, excepted. If Tenant fails to complete the restoration before expiration of
the Term, Landlord may complete the restoration and charge the cost of the restoration to Tenant. Notwithstanding the foregoing, Tenant shall have no obligation to restore the Premises to its condition prior to the construction of the Tenant
Improvements contemplated by Paragraph 1.5. 
 14.2 Before proceeding with any Change (exclusive only of changes to items constituting
Tenant’s personal property), Tenant shall submit to Landlord plans and specifications for the work to be done, which shall in all cases require Landlord’s prior written approval, which approval shall not be unreasonably withheld or
delayed. At Tenant’s sole cost and expense Landlord may confer with consultants in connection with the review of such plans and specifications. If Landlord or such consultant(s) shall disapprove of any of the Tenant’s plans, Tenant shall
be advised of the reasons of such disapproval. In any event, Tenant agrees to pay to Landlord, as additional rent, the reasonable out of pocket cost of such consultation and review immediately upon receipt of invoices either from Landlord or such
consultant(s). Any Change for which approval has been received shall be performed in accordance with the approved plans and specifications, and no material amendments or additions to such plans and specifications shall be made without the prior
written consent of Landlord. 
 Landlord agrees to endeavor to respond to any request by Tenant for approval of Changes which approval is required hereunder
within fifteen (15) business days after delivery of Tenant’s written request; Landlord’s response shall be in writing and, if Landlord withholds its consent, Landlord shall specify in reasonable detail in Landlord’s notice of
disapproval, the basis for such disapproval. If Landlord delivers to Tenant notice of Landlord’s disapproval of any plans, Tenant may revise Tenant’s plans to incorporate the changes suggested by Landlord in Landlord’s notice of
disapproval, and resubmit its plans to Landlord. Landlord shall not have the right to charge any construction administration or supervision fee in connection with Tenant’s 

  
 23 

 
performance of Changes provided that Landlord shall be entitled reimbursement from Tenant for Landlord’s third party out of pocket costs incurred in connection with the review by Landlord of
any Changes proposed by Tenant. 
 14.3 Notwithstanding anything to the contrary contained in this Lease, Tenant, without Landlord’s
prior written consent, shall be permitted to make Cosmetic Alterations, provided that: (a) Tenant shall notify Landlord in writing within thirty (30) days of completion of the Cosmetic Alteration, and (b) Tenant shall upon
Landlord’s request, remove the Cosmetic Alteration at the termination of the Lease and restore the Leased Premises to their condition prior to such Cosmetic Alteration. As used herein, the term “Cosmetic Alterations” shall mean
any modification to the Premises not involving any material penetration of any walls of the Premises or any material modifications of the floor (other than carpeting) or ceiling of the Premises and shall include, without limitation, the hanging of
paintings or decorative accessories on any interior walls of the Premises, any painting of the interior walls of the Premises as well as the installation or replacement of any carpet or other floor covering in all or any portion of the Premises, and
on an aggregate basis in any one year do not cost in excess of Two Hundred Thousand Dollars ($200,000) provided that any installation or replacement of carpeting by Tenant shall not be subject to the Two Hundred Thousand Dollar ($200,000)
limitation. 
 14.4 If the proposed Change requires approval by or notice to the lessor of a superior lease or the holder of a mortgage,
Landlord will promptly give Tenant notice of such requirement, and no Change shall be commenced until such approval has been received, or such notice has been given, as the case may be, and all applicable conditions and provisions of said superior
lease or mortgage with respect to the proposed Change or alteration have been met or complied with, at Tenant’s expense; and Landlord, if it approves the Change, will request such approval or give such notice, as the case may be. 

14.5 Tenant shall submit to Landlord the name and address of each contractor intended to be used by Tenant in connection with construction of
Changes; Landlord’s approval of any contractor shall not be unreasonably withheld, conditioned or delayed. If Landlord does not object to a contractor within ten (10) business days of receipt of Tenant’s written notification of the
identity of the contractor, Landlord shall be deemed to have approved the contractor. No contractor which is unacceptable to Landlord shall be engaged by Tenant. All costs and expenses incurred in Changes shall be paid by Tenant prior to
delinquency. If Landlord approves the construction of specific interior improvements in the Premises by contractors or mechanics selected by Tenant and approved by Landlord, then Tenant’s contractors shall obtain on behalf of Tenant and at
Tenant’s sole cost and expense, (i) all necessary governmental permits and certificates for the commencement and prosecution of Tenant’s Changes and for final approval thereof upon completion and (ii) at Landlord’s
reasonable request with respect to any Change or Changes which exceed $150,000.00 in cost, evidence, as may be reasonably satisfactory to Landlord, that Tenant has sufficient financial capacity to bear the cost of the anticipated Change. In the
event Tenant shall request any Changes in the work to be performed after the submission of the plans referred to in this Paragraph 14 (other than de minimis changes which would qualify as “change directives” as opposed to “change
orders” in accordance with applicable ALA. standards), such additional Changes shall be subject to the same approvals and notices as the Changes initially submitted by Tenant. 

  
 24 

 14.6 All Changes and the performance thereof shall at all times comply with (i) all laws,
rules, orders, ordinances, directions, regulations and requirements of all governmental authorities, agencies, offices, departments, bureaus and boards having jurisdiction thereof, (ii) all rules, orders, directions, regulations and
requirements of the Pacific Fire Rating Bureau, or of any similar insurance body or bodies, and (iii) all commercially reasonable rules and regulations of Landlord of which Landlord has notified Tenant in writing, and Tenant shall cause Changes
to be performed in compliance therewith and in good and first class workmanlike manner, using materials and equipment at least equal in quality and class to the installations of the Building. Changes shall be performed in such manner as not to
unreasonably interfere with the occupancy of any other tenant in the Building nor delay or impose any additional expense upon Landlord in construction, maintenance or operation of the Building, and shall be performed by Contractors or mechanics
approved by Landlord and submitted to Tenant pursuant to this Paragraph, who shall coordinate their work in cooperation with any other work being performed with respect to the Site and/or the Building. Throughout the performance of Changes, Tenant,
at its expense, shall carry, or cause to be carried, workers’ compensation insurance in statutory limits, and general liability insurance for any occurrence in or about the Building, of which Landlord and its managing agent, whose identity
Landlord shall provide to Tenant in writing, shall be named as parties insured, in such limits as Landlord may reasonably prescribe, with insurers reasonably satisfactory to Landlord all in compliance with Paragraph 21.2. Notwithstanding any
provision of this Lease to the contrary, in no event shall Landlord be required to undertake any alteration or any improvements of any kind whatsoever in connection with the Premises or the Building as a result of or in connection with any Changes
being made by Tenant (unless and to the extent that such alteration is necessary as a result of the warranty by Landlord contained in Paragraph 13 above being incorrect in any fashion). Without limitation to the foregoing, except as expressly set
forth in the immediately preceding sentence, Landlord shall not be required to make any improvements or alteration of any kind whatsoever in order to comply with any applicable laws, orders, ordinances, regulations or building codes which may be
required in connection with Changes being made by Tenant. 
 14.7 Tenant further covenants and agrees that any mechanic’s lien filed
against the Premises or against the Building for work claimed to have been done for, or materials claimed to have been furnished to Tenant, will be discharged by Tenant, by bond (pursuant to California Civil Code Section 8424) or otherwise,
within thirty (30) days after notice to Tenant of the filing thereof, at the cost and expense of Tenant. All alterations, decorations, additions or improvements upon the Premises, made by either party, including (without limiting the generality
of the foregoing) all wall covering, built-in cabinet work, paneling and the like, shall, unless Landlord elects otherwise as described above in Paragraph 14.1(g), become the property of Landlord, and shall remain upon, and be surrendered with the
Premises, as a part thereof, at the end of the Term hereof. Notwithstanding the immediately preceding sentence, Landlord may, by written notice given to Tenant at least thirty (30) days prior to the end of the Term, require Tenant to remove all
partitions, counters, railings and like installed by Tenant and Tenant shall repair any damage to the Premises arising from such removal. Notwithstanding the immediately preceding sentence, Tenant shall not be required to remove or restore any
Changes which Landlord did not require to be removed in accordance with the provisions of Paragraph 14.1(g). 

  
 25 

 14.8 All articles of personal property and all business and trade fixtures, machinery and
equipment, furniture and movable partitions owned by Tenant or installed by Tenant at its expense in the Premises shall be and remain the property of Tenant. Tenant may remove such items at Tenant’s sole cost and expense at any time during the
Term, and Tenant shall repair any damage caused by such removal. Tenant shall restore and repair all damage to the Premises caused by such removal, and shall otherwise perform such removal in accordance with Landlord’s reasonably imposed
scheduling and other requirements. If Tenant shall fail to remove all of its effects from said Premises upon termination of this Lease for any cause whatsoever, Landlord may, at its option, remove the same in any manner that Landlord shall choose,
and store said effects without liability to Tenant for loss thereof. Tenant agrees to pay Landlord upon demand any and all expenses incurred in such removal, including court costs and attorneys’ fees and storage charges on such effects for any
length of time that the same shall be in Landlord’s possession, or Landlord may, at its option, without notice, sell said effects, or any of the same, at private sale and without legal process, for such price as Landlord may obtain. Landlord
shall apply such proceeds of such sale upon any amounts due under this Lease from Tenant to Landlord and upon the expense incident to the removal and sale of said effects. 

14.9 Subject to the other provisions of this Lease (including Paragraphs 1.3 and 17), Landlord reserves the right at any time and from time to
time without the same constituting an actual or constructive eviction and without incurring any liability to Tenant therefor or otherwise affecting Tenant’s obligations under this Lease, to make such changes, alterations, additions,
improvements, repairs or replacements in or to the Site or the Building (including the Premises if required so to do by any law or regulation) and to the fixtures and equipment thereof, as well as in or to the street entrances, halls, passages and
stairways thereof; provided that Landlord shall use commercially reasonable efforts to avoid unreasonable interference with Tenant’s access to and use of the Premises. Without limiting the foregoing, Landlord may change the name by which the
Building is commonly known, as Landlord may deem necessary or desirable. Nothing contained in this Paragraph 14, shall be deemed to relieve Tenant of any duty, obligation or liability of Tenant with respect to the terms, covenants and conditions of
this Lease, to making any repair, replacement or improvement required hereby, or to complying with any law, order or requirement of any government or other authority. Nothing contained in this Paragraph 14 shall be deemed or construed to impose upon
Landlord any obligation, responsibility or liability whatsoever, for the care, supervision of repair of the Site, the Building and/or the Premises or any part thereof other than as provided in this Lease. 

14.10 The construction of the Tenant Improvements pursuant to the provisions of the Work Letter attached to this-Lease as Exhibit B
shall be governed by the terms of such Work Letter to the extent inconsistent with the provisions of this Paragraph 14. 
 14.11 Within
thirty (30) days of completion of any Changes (other than for mere decorative Changes), Tenant shall provide Landlord with a set of final “as-built” plans. 

14.12 Tenant may, at its own expense, install its own security system (“Tenant’s Security System”) in the Premises,
subject to Landlord’s prior written consent, which consent shall not be unreasonably withheld or delayed; provided, however, that (A) if Tenant’s Security System ties into the Building security system, Tenant shall coordinate the
installation and operation of Tenant’s Security System with Landlord to assure that Tenant’s Security System is 

  
 26 

 
compatible with the Building security system and the Building Systems, and (B) to the extent that Tenant’s Security System is not compatible with the Building security system or the
Building Systems, Tenant shall not be entitled to install or operate it. Tenant shall be solely responsible, at Tenant’s sole cost and expense, for the monitoring, operation and removal of Tenant’s Security System, provided that,
notwithstanding the foregoing, Tenant may install any security system it desires that does not require linkage with the Building security system and which does not affect the Building security system and which does not (i) create (a) an
adverse effect on the structural integrity of the Building, (b) a non-compliance with any applicable laws, (c) an adverse effect on the Building Systems, (d) an effect on the exterior appearance of the Building, or
(e) unreasonable interference with the normal and customary office operations of any other tenant in the Building, or (ii) adversely affect Landlord’s ability to operate the Building. Tenant shall provide Landlord with any information
reasonably required regarding Tenant’s Security System in the event access to the Premises is necessary in an emergency. Upon the expiration or earlier termination of the Term, at Landlord’s option, the Tenant’s Security System shall
become the property of Landlord and be surrendered to Landlord with the Premises. In furtherance of the same, Landlord shall have the right to require Tenant to convey the Tenant’s Security System to Landlord free of all liens at the end of the
Term, at no cost to Landlord, pursuant to a commercially reasonable form of bill of sale or other conveyance agreement to be executed by Tenant. Further, at the expiration or early termination of this Lease, Landlord shall be entitled to require
that Tenant remove Tenant’s Security System from the Building at its cost and repair any and all damage resulting from any such removal. 
 15.
Repairs and Maintenance. 
 15.1 Tenant acknowledges that Landlord shall be responsible for repairing and maintaining, in first-class
condition and repair, the Building and all components and systems which are a part of or serve the Building, and the corresponding costs of maintenance and repairs shall be included as part of the Direct Operating Expenses or Common Operating
Expenses, as the case may be, paid by Tenant: pursuant to, and subject to the limitations contained in, Paragraph 5 or Paragraph 6 as the case maybe. Tenant shall upon the expiration or sooner termination of the Term surrender the Premises to
Landlord in good condition, reasonable wear and tear and items for which Landlord bears sole responsibility for the cost of repair and maintenance excepted. Landlord shall have no obligation to alter, remodel, improve, decorate or paint the Premises
or any part thereof in anticipation of Tenant’s occupancy of the Premises (except as may be necessary in order for Landlord to be in compliance with the warranty set forth in Paragraph 13 above and as otherwise provided in the Work Letter and
this Lease), and the parties hereto affirm that Landlord has made no representations to Tenant respecting the condition of the Premises except as specifically set forth in this Lease. “Building Systems” shall mean any plant,
machinery, transformers, duct work, cable, wires, and other equipment, facilities, and systems designed to supply heat, ventilation, air conditioning and humidity, life-safety or any other services or utilities, or comprising or serving as any
component or portion of the electrical, gas, steam, plumbing, sprinkler, communications, alarm, security, or fire/life safety systems or equipment, or any other mechanical, electrical, electronic, computer or other systems or equipment which serve
the Building in whole or in part. 
 15.2 Landlord shall repair and maintain in first-class condition and repair and in compliance with all
laws the structural components of the Building and Premises (consisting of 

  
 27 

 
the exterior and other load bearing walls, footings, columns, structural floors and foundations). The cost of any and all such repairs shall be included as part of the Direct Operating Expenses
or Common Operating Expenses, as the case may be, and paid by Tenant pursuant to and subject to the limitations contained in, Paragraph 5 or Paragraph 6 as the case may be. Landlord shall not be liable for any failure to make any repairs, or to
perform any maintenance, required of Landlord unless such failure shall persist for an unreasonable time after written notice of the need of such repairs or maintenance is given to Landlord by Tenant. There shall be no abatement of rent and no
liability of Landlord by reason of any injury to or interference with Tenant’s business arising from the making of any repairs, alterations or improvements in or to any portion of the Premises or in or to fixtures, appurtenances and equipment
therein. Tenant hereby waives the provisions of California Civil Code Sections 1932(1), 1941 and 1942 and of any similar law, statute or ordinance now or hereafter in effect. Landlord expressly reserves the right to access the Premises and all parts
of the Building as required to perform its maintenance obligations hereunder. Notwithstanding any of the provisions of this Lease to the contrary, if Tenant provides notice (or which maybe telephonic to the Building’s property management office
in the event of an Emergency, defined below) to Landlord of an event or circumstance which requires the action of Landlord with respect to repair and/or maintenance of the Building, including the Building structure and/or Building Systems, which
event or circumstance with respect to the Building structure or Building Systems materially and adversely affects the conduct of Tenant’s business from the Premises (or any material portion), and Landlord fails to commence corrective action not
later than five (5) business days after receipt of such notice, then Tenant may proceed to take the required action upon delivery of an additional one (1) business day’s notice to Landlord specifying that Tenant is taking such
required action (provided, however, that the initial five (5) business day notice and the subsequent one (1) business day notice shall not be required in the event of an Emergency), and if such action is not commenced by Landlord within
such one(l) business day period and thereafter diligently pursued to completion, then Tenant shall be entitled to take such action in the manner described below and shall be further entitled to prompt reimbursement by Landlord of Tenant’s
reasonable costs and expenses in taking such action plus interest thereon at the Interest Rate (hereinafter defined). If Tenant takes any such action, Tenant shall use only those contractors used by Landlord in the Building for work unless such
contractors are unwilling or unable to perform, or timely perform such work, in which event Tenant may utilize the services of any other qualified contractor which normally and regularly performs similar work in Comparable Buildings. Promptly
following completion of any work taken by Tenant pursuant to this Paragraph 15.2, Tenant shall deliver a detailed invoice of the work completed, the materials used and the costs relating thereto. If Landlord delivers to Tenant, within thirty
(30) days after receipt of Tenant’s invoice, a written objection to the payment of such invoice, setting forth with reasonable particularity Landlord’s reasons for its claim that such action did not have to be taken by Landlord
pursuant to this Lease or that the charges are excessive (in which case Landlord shall pay the amount it contends would not have been excessive), then Landlord and Tenant shall thereafter attempt to resolve the dispute regarding such charges and in
the event of a failure to achieve resolution Tenant may proceed to file a claim against Landlord. If Tenant prevails in such claim, the amount of the award shall include interest at the Interest Rate from the time of each expenditure by Tenant until
the date Tenant receives such amount by payment or offset and reasonable attorneys’ fees and related costs. For purposes of this Paragraph 15.2, an “Emergency” shall mean an event threatening immediate and material danger to
people located in the Building or 

  
 28 

 
immediate, material damage to the Building, Building Systems, Building structure, Premises, or creates a realistic possibility of an immediate and material interference with, or immediate and
material interruption of a material aspect of Tenant’s business operations. 
 16. Liens. Tenant shall not permit any mechanic’s,
material men’s or other liens to be filed against the real property of which the Site, the Building, and/or the Premises form a part, nor against the Tenant’s leasehold interest in the Premises. Landlord shall have the right at all
reasonable times to post and keep posted on the Premises any notices which it deems necessary for protection from such liens. Notwithstanding any other provision in this Lease to the contrary, if any such liens are filed, and the same are not
removed by Tenant within thirty (30) days after notice to Tenant of such filing, Landlord may, without waiving its rights and remedies based on such breach of Tenant and without releasing Tenant from any of its obligations, upon notice to
Tenant, cause such liens to be released by any means it shall deem proper, including payment in satisfaction of the claim giving rise to such lien. Thereafter Tenant shall promptly pay to Landlord, upon notice by Landlord, any sum paid by Landlord
to remove such liens, together with interest at the lesser of 10% or the maximum rate per annum permitted by law from the date of such payment by Landlord. 

17. Entry by Landlord. Subject to limitations described in the last paragraph of Paragraph 1.3 and this Paragraph 17 below, Landlord reserves
and shall at any and all reasonable times and upon reasonable prior notice to Tenant of not less than twenty four (24) hours (except in the case of emergency) have the right to enter the Premises to inspect the same, to supply any service to be
provided by Landlord to Tenant hereunder, to submit said Premises to prospective purchasers or mortgagors/lenders or, to post notices of non-responsibility, to alter, improve or repair the Premises or any other portion of the Building, to show the
Premises during the last twelve (12) months of the Term of this Lease to prospective tenants, all without being deemed guilty of any eviction of Tenant and without abatement of rent except as expressly set forth below in this Paragraph 17. In
order to carry out such purposes, Landlord may erect scaffolding and other necessary structures where reasonably required by the character of the work to be performed, provided that the business of Tenant shall be interfered with as little as is
reasonably practicable. Notwithstanding anything to the contrary set forth in this Paragraph 17, Tenant may designate in writing certain reasonable areas of the Premises as “Secured Areas” should Tenant require such areas for the
purpose of securing certain valuable property or confidential information. In connection with the foregoing, Landlord shall not enter such Secured Areas except in the event of an emergency. Landlord need not clean any area designated by Tenant as a
Secured Area and shall only maintain or repair such Secured Areas to the extent (i) such repair or maintenance is required in order to maintain and repair the Building; (ii) as required by applicable law, or (iii) in response to
specific requests by Tenant and in accordance with a schedule reasonably designated by Tenant, subject to Landlord’s reasonable approval. Tenant hereby waives any claim for damages for any injury or inconvenience to or interference with
Tenant’s business, any loss of occupancy or quiet enjoyment of the Premises, and any other loss occasioned thereby except as expressly set forth herein. For each of the aforesaid purposes, Landlord shall at all times have and retain a key with
which to unlock all of the doors in, upon and about the Premises (excluding Tenant’s vaults and safes), and Landlord shall have the means which Landlord may deem proper to open said doors in an emergency in order to obtain entry to the
Premises. Any entry to the Premises obtained by Landlord by any of said means shall not, under any circumstances, be construed or deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an

  
 29 

 
eviction of Tenant from the Premises or any portion thereof. It is understood and agreed that no provision of this Lease shall be construed as obligating Landlord to perform any repairs,
alterations or decorations except as otherwise expressly agreed herein to be performed by Landlord. In the event that Tenant is prevented from using, and does not use, the Premises or any material portion thereof, as a result of (i) any repair,
maintenance or alteration performed by Landlord, or which Landlord failed to perform or commence to perform after at least three (3) business days’ prior written notice by Tenant to Landlord identifying such failure, which substantially
interferes with Tenant’s use of or ingress to or egress from the Building or Premises and is not necessitated by Tenant’s breach or Default hereunder or performed in such manner at the Tenant’s express request; (ii) any failure
to provide services, utilities or ingress to and egress from the Building or Premises if such failure is attributable solely to the act or omission of Landlord (or Landlord’s agents, employees or contractors) or to Landlord’s failure to
perform its maintenance obligations set forth herein as specifically identified in a written notice given by Tenant to Landlord; or (iii) the presence of Hazardous Materials due to the acts or omissions of Landlord or Landlord’s agents,
employees or contractors (any such set of circumstances as set forth in items (i) through (iii), above, to be known as an “Abatement Event”), then if such Abatement Event continues for five (5) consecutive business days
(the “Eligibility Period”), then the rent payable hereunder shall be abated or reduced, as the case may be, after expiration of the Eligibility Period for such time that Tenant continues to be so prevented from using, and does not
use, the Premises, or any material portion thereof, in the proportion that the rentable area of the portion of the Premises that Tenant is prevented from using, and does not use, bears to the total rentable area of the Premises. If Tenant’s
right to abatement occurs during a free rent period, Tenant’s free rent period shall be extended for the number of days that the abatement period overlapped the free rent period (“Overlap Period”). 

18. Utilities and Services. Landlord agrees during the period from and after the Early Access Date and thereafter during the Lease Term to furnish to
the Premises Monday through Friday from 7:00 a.m. through 7:00 p.m., holidays excepted, (unless otherwise stated below), 
 (a) electric
current for normal lighting and fractional horsepower office machines, electricity in an amount not less than 1.0 watts per rentable square foot for lighting and 5.0 watts per rentable square foot for convenience power, 

(b) hot and cold water for lavatory, kitchen/pantry and drinking purposes, 

(c) elevator service by non-attended automatic elevators, 

(d) regular refuse removal, 

(e) HVAC service sufficient to maintain comfortable temperatures throughout the Premises (i.e., no higher than 75° Fahrenheit with 50%
relative humidity in the summer, and no lower than 72° Fahrenheit in the winter with 45% relative humidity) and 
 (f) washing of all
exterior windows at least three (3) times per calendar year (collectively, “Base Building Services”). 
 Landlord
shall have no responsibility to provide cabling or equipment to allow Tenant to obtain telecommunications and network connectivity and Landlord agrees that Tenant may select 

  
 30 

 
its own vendors and providers of telecommunications and network connectivity service. Landlord shall allow such providers to install their own cabling, conduits and equipment in the Building and
Premises subject to Landlord’s prior approval of the specific plans and specifications therefor in accordance with Exhibit B or if after the completion of the Tenant Improvements Paragraph 14 above. Subject to Landlord’s rules,
regulations, and restrictions and the terms of this Lease and applicable laws, Landlord shall permit Tenant, at no additional charge to Tenant, to utilize Tenant’s Share of the existing Building risers, raceways, and shafts available for use by
the tenants and occupants of the Building to the extent (i) there is available space in the Building risers, raceways, and/or shafts for Tenant’s use, which availability shall be determined by Landlord in Landlord’s reasonable
discretion, and (ii) Tenant’s requirements are consistent with the requirements of a typical general office user. The electrical services, and water (and sewer) provided to the Premises shall be separately metered to measure the
consumption of electricity and water within the Premises, with Landlord to install all such meters at its expense as soon as reasonably practicable following the Early Access Date to the extent such meters are not in place as of such date. Tenant
shall pay Landlord directly as part of the Direct Operating Expenses for all utilities consumed within the Premises, as measured by such separate meters. Landlord shall provide janitorial services to Tenant with respect to the Premises in accordance
with the Specifications attached hereto as Exhibit D and the charge for such services shall be included as a portion of the Direct Operating Expenses or in the alternative, Tenant shall be entitled to engage a third party vendor to provide
janitorial services for the Premises and in such event Tenant shall timely pay any and all costs of such third party vendor, Tenant shall directly contract for any and all security services with respect to the Premises and the cost of such services
shall be paid directly by Tenant. Except as expressly set forth hereby, Landlord shall not be liable for, and Tenant shall not be entitled to any abatement or reduction of rent by reason of Landlord’s failure to furnish any of the Base Building
Services when such failure is caused by accident, breakage, repairs, strikes, lockouts or other labor disturbances or labor disputes of any character/or for other causes beyond Landlord’s reasonable control. Landlord’s cost of providing
such utility services shall be part of Direct Operating Expenses, Tenant hereby waives the provisions of California Civil Code Section 1932(1) or any other applicable existing or future law, ordinance or governmental regulation permitting the
termination of this Lease due to the interruption or failure of or inability to provide any services required to be provided by Landlord hereunder. In the event Tenant requires heat and/or air conditioning outside of the business hours specified
above, Tenant shall pay to Landlord as additional rent the sum of Eighty-Five Dollars ($85.00) per hour per zone, for each hour of occupancy outside of the business hours specified above. Landlord represents and warrants that the Premises includes
thermostats and Building management system automated controls for the HVAC service within the Premises, and that Tenant may control the temperatures maintained within the Premises during normal business hours. All charges levied against Tenant for
utility and janitorial (if applicable) services together with charges for any and all Base Building Services shall be paid by Tenant to Landlord as reimbursement for any and all such costs and in accordance with the provisions of Paragraph 6.2and
6.3 above in a manner consistent with reimbursement to Landlord of Tenant’s Share of Common Operating Expenses. Any incandescent light bulbs used in the Premises shall be paid for by the Tenant. Upon Tenant’s request, Landlord’s
personnel shall install incandescent light bulbs or other Building nonstandard bulbs in the Premises. Tenant agrees to pay Landlord upon demand Landlord’s cost for the maintenance and/or replacement, as applicable, of all such incandescent
light bulbs installed or 

  
 31 

 
other Building nonstandard improvements; provided, that Landlord shall not be responsible in any manner for said maintenance, cleaning and repair. Landlord shall provide Tenant access to the
Premises on a twenty-four (24) hour per day, seven (7) days per week basis, subject to events beyond Landlord’s reasonable control. 
 19.
Indemnification. 
 19.1 To the fullest extent permitted bylaw, but subject to Paragraph 21.6 and except to the extent caused by the
negligence or misconduct of Landlord or its agents, contractors, employees or invitees, or by Landlord’s breach of this Lease, Tenant hereby agrees to defend, indemnify, protect and hold Landlord and Landlord Parties harmless against and from
any and all loss, cost, damage or liability arising in whole or in part from (i) Tenant’s use of the Site, the Building, and/or the Premises, (ii) the conduct of its business or from any activity, work, or thing done, permitted or
suffered by Tenant, its agents, contractors, employees or invitees in or about the Site, the Building, and/or the Premises arising from any act, neglect, fault or omission of Tenant, or of its agents, employees or invitees, and (iii) from and
against all costs, attorneys’ fees, expenses and liabilities incurred for such claim or any action or proceeding brought thereon. In case any action or proceeding is brought against Landlord and/or any of the Landlord Parties by reason of any
such claim, Tenant upon notice from Landlord hereby agrees to defend Landlord and the Landlord Parties at Tenant’s expense by counsel approved in writing by Landlord. Tenant, as a material part of the consideration to Landlord, hereby assumes
all risk of damage to property or injury to persons in, upon or about the Site, the Building, and/or the Premises from any cause whatsoever except that which is caused by Landlord’s or its agents, contractors, employees or invitees, negligence
or intentional misconduct or breach of this Lease, and Tenant hereby waives all its claims in respect thereof against Landlord. 
 19.2 To
the fullest extent permitted by law, but subject to Paragraph 21.6, Landlord hereby agrees to defend, indemnify, protect and hold Tenant harmless against and from any and all loss, cost, damage or liability suffered by Tenant arising in whole or in
part from the negligence (to the extent not covered by liability insurance carried by Tenant pursuant to this Lease) or misconduct of Landlord or its agents, contractors, employees or invitees in or about the Site, the Building, and/or the Premises,
including without limitation any liability or injury to the person or property of Tenant, its officers, directors, partners, employees, agents, invitees or guests. In case any action or proceeding is brought against Tenant by reason of any such
claim, Landlord upon notice from Tenant hereby agrees to defend Tenant at Landlord’s expense by counsel approved in writing by Tenant (provided, that any counsel appointed by an insurance carrier shall be deemed acceptable to Tenant). Nothing
herein shall relieve Tenant of liability for its own willful acts or negligence. 
 20. Damage to Tenant’s Property. Notwithstanding the
provisions of Paragraph 19 to the contrary, except to the extent caused by the negligence (to the extent not covered by liability insurance carried by Tenant pursuant to this Lease) or misconduct of Landlord or its agents, contractors, employees or
invitees, or Landlord’s breach of this Lease, Landlord and each of the Landlord Parties shall not be liable for any damage to property entrusted to employees of the Building, or for loss of or damage to any property by theft or otherwise, or
for any injury or damage to persons or property resulting from fire, explosion, falling plaster, steam, gas, electricity, water or rain which may leak from any part of the Building (including, but not limited

  
 32 

 
to, the Premises) or from the pipes, appliances or plumbing works therein or from the roof, street or sub-surface or from any other place or resulting from dampness or any other patent or latent
cause whatsoever. Landlord and each of the Landlord Parties shall not be liable for interference with the light, air, view or intangible characteristics or qualities of the Premises; provided, however, that Landlord agrees not to voluntarily
construct any improvements or other structures which would materially interfere with the light, air, the view available at the Premises, unless such construction is required by applicable law. Tenant shall give prompt notice to Landlord in case of
fire or accidents in the Premises or in the Building or of defects known to Tenant therein or in the fixtures or equipment located therein. Notwithstanding any provision of Paragraph 19 to the contrary, (i) neither Landlord nor any partner,
director, officer, member, agent, servant or employee of Landlord shall be liable: for any such damage caused by other tenants or persons in, upon or about the Building, or caused by operations in the construction of any private, public or
quasi-public work (the limitations of liability set forth in this clause (i) shall not apply to any damage or liability caused by the negligence (to the extent not covered by liability insurance carried by Tenant pursuant to this Lease) or
intentional misconduct of Landlord Parties); and (ii) neither party hereto shall be liable to the other for consequential damages, including lost profits, of the other party or any person claiming through or under the other party (except, in
the case of Tenant’s liability, as described in Paragraph 11 above). 
 21. Insurance. 

21.1 During the Term hereof, Tenant, at its sole expense, shall obtain and keep in force the following insurance: 

(a) Commercial general liability (“CGL”) insurance designating Landlord as an additional insured against claims for bodily
injury and property damage occurring in, or about the Premises (including without limitation damage or injury to vehicles or persons in the parking lot located on the Site) arising out of Tenant’s use and occupancy of the Premises. Such
insurance shall have a combined single limit of not less than Three Million Dollars ($3,000,000) per occurrence with a Five Million Dollar ($5,000,000) aggregate limit (such limits maybe achieved by a combination of primary and umbrella coverages).
Such liability insurance shall be primary and not contributing to any insurance available to Landlord and any insurance maintained by Landlord shall be excess thereto. In no event shall the limits of such insurance be considered as limiting the
liability of Tenant under this Lease. 
 (b) Personal property insurance insuring all equipment, trade fixtures, inventory, fixtures and
personal property located on or in the Premises for perils covered by the causes of loss - special form (all risk) and in addition, boiler and machinery (if applicable). Such insurance shall be written on a replacement cost basis in an amount equal
to the full replacement value of the aggregate of the foregoing less any applicable deductible. 
 (c) Workers’ compensation insurance
in accordance with statutory law. 
 (d) Loss of income and extra expense insurance in such amounts as will reimburse Tenant for direct or
indirect loss of earnings attributable to all perils commonly insured against by prudent tenants or attributable to prevention of access to the Premises as result of such perils. 

  
 33 

 21.2 The policies required to be maintained by Tenant hereunder shall be with companies rated
A-VIII or better in the most current issue of Best’s Insurance Reports. Insurers shall be authorized to do business in the State of California and domiciled in the USA. Any deductible amount under any insurance policies required hereunder shall
not exceed Fifty Thousand Dollars ($50,000) without Landlord’s prior written consent, which consent will not be unreasonably withheld. Certificates of insurance shall be delivered to Landlord prior to the Tenant’s entry onto the Premises
to fixturize the Premises and annually thereafter at least ten (10) days prior to the expiration date of the old policy. Tenant shall have the right to provide insurance coverage which it is obligated to carry pursuant to the terms hereof in
either or both a blanket or umbrella policy, provided such blanket or umbrella policy expressly affords coverage to the Premises and to Landlord as required by this Lease. Each policy of insurance, to the extent consistent with insurance industry
practices for the type of insurance, shall provide that Landlord (and any mortgagee) are additional insureds and shall provide notification to Landlord at least thirty (30) days prior to any cancellation or modification to reduce the insurance
coverage; Landlord expressly acknowledges that, as of the Effective Date, a majority of insurers are not willing to provide notice to third parties (including landlords) of cancellation or modification or insurance coverage as described in this
sentence, and agrees that for so long as Tenant’s insurer(s) is unwilling to provide such notice, Tenant shall be obligated to promptly provide such notice to Landlord upon receipt of any such notice by Tenant from Tenant’s insurer(s),

 21.3 Landlord shall maintain: 

(a) fire and casualty insurance, with loss payable to Landlord and to any Mortgagee, insuring against loss or damage to the Building. The
amount of such insurance shall be equal to the estimated replacement cost of the Building (as the same may increase during the Term), exclusive of foundations, as the same shall exist from time to time, but in no event more than the commercially
reasonable and available insurable value thereof if, by reason of the unique nature or age of the improvements involved, such latter amount is less than full replacement cost. Landlord’s policy shall contain at least twelve (12) months of
“rental income loss” coverage payable in instances in which Tenant is entitled to rent abatement hereunder, and shall include (i) an “extended coverage” endorsement, (ii) a “building laws” and/or “law and
ordinance” coverage endorsement that covers “costs of demolition,” “increased costs of construction” due to changes unbuilding codes and “contingent liability” with respect to undamaged portions of the Building,
and (iii) an “earthquake sprinkler leakage” endorsement, with each such endorsement to be of a kind required by Landlord to assist Landlord in funding its obligations under this Lease to repair and restore the Building; 

(b) CGL insurance against claims for bodily injury and property damage occurring in or about the Building in amounts as shall from time to
time be carried by owners and operators of Comparable Buildings, but in no event less than Five Million Dollars ($5,000,000) with respect to bodily injury, personal injury or death to any one person and no less than Five Million Dollars ($5,000,000)
for each accident with respect to property damage (including both primary and excess coverage), with a commercially reasonable deductible. 

Tenant shall reimburse Landlord for Tenant’s Share of the premiums for fire and casualty, and liability insurance (subject to proration
to the extent the premium covers a period 

  
 34 

 
prior or subsequent to the Term) as part of the Common Operating Expenses to be paid by Tenant. The insurance required by this Paragraph shall, in addition, include coverage for any additional
costs resulting from debris removal and reasonable amounts of coverage for the enforcement of any ordinance or law regulating the reconstruction or replacement of any undamaged sections of the Premises required to be demolished, and shall also
contain an agreed valuation provision in lieu of any coinsurance clause and waiver of subrogation. If such insurance coverage has a deductible clause, then Common Operating Expenses shall include the full deductible amount; provided, however, that
such deductible amount is reasonably commensurate with the levels of deductibles then being maintained by owners of Comparable Buildings and further provided that the deductible amount included in Common Operating Expenses shall be prorated as
provided Paragraph 6.2. Landlord shall not be required to insure against any damage caused by flood, terrorism, mold or environmental contamination. 

21.4 Tenant will not knowingly keep, use, sell, or offer for sale in, or upon, the Premises any article which may be prohibited by any
insurance policy periodically in force covering the Premises. If Tenant’s occupancy or business in, or on, the Premises, whether or not Landlord has consented to the same, results in any increase in premiums for the insurance required or
actually carried by Tenant and/or Landlord with respect to the Premises, Tenant shall pay any such increase in premiums as additional rent. In determining whether increased premiums are a result of Tenant’s use of the Premises, a schedule
issued by the organization computing the insurance rate on the Premises showing the various components of such rate, shall be conclusive evidence of the several items and charges which make up such rate. Tenant shall promptly comply with all
reasonable requirements of the insurance authority or any present or future insurer relating to the Premises. 
 21.5 If any insurance
policy required to be maintained by Tenant shall be canceled or cancellation shall be threatened or the coverage thereunder reduced or threatened to be reduced in any way because of the specific use of the Premises or any part thereof by Tenant or
any assignee or sub-tenant of Tenant or by anyone Tenant permits on the Premises and, if Tenant fails to remedy the condition giving rise to such cancellation, threatened cancellation, reduction of coverage, threatened reduction of coverage,
increase in premiums, or threatened increase in premiums, within five (5) business days after written notice thereof, Landlord may, at its option, enter upon the Premises and attempt to remedy such condition, and Tenant shall promptly pay all
costs thereof to Landlord as additional rent. Landlord shall not be liable for any damage or injury caused to any property of Tenant or of others located on the Premises resulting from such entry. If Landlord is unable, or elects not, to remedy such
condition, then Landlord shall have all of the remedies provided for in this Lease in the event of a Default by Tenant. 
 21.6
Notwithstanding anything in this Lease to the contrary, Landlord and Tenant hereby mutually waive their respective rights of recovery against each other for any loss of, or damage to, either parties’ property, to the extent that such loss or
damage is insured by an insurance policy required to be in effect at the time of such loss or damage or is otherwise actually insured by an insurance policy maintained by the waiving party. Each party shall obtain any special endorsements, if
required by its insurer whereby the insurer waives its rights of subrogation against the other party. 

  
 35 

 21.7 In the event Tenant does not purchase the insurance required by this Lease or keep the same
in full force and effect, Landlord may, but shall not be obligated to, upon notice to Tenant, purchase the necessary insurance and pay the premium. The Tenant shall repay to Landlord, as additional rent, the amount so paid promptly upon demand. In
addition, Landlord may recover from Tenant and Tenant agrees to pay, as additional rent, any and all reasonable expense (including attorneys’ fees) and damages which Landlord may sustain by reason of the failure to Tenant to obtain and maintain
such insurance. 
 22. Damage or Destruction. 

22.1 In the event of any casualty damage which affects the Premises or the Building outside the boundaries of the Premises, Landlord will,
within sixty (60) days following the date of the damage, deliver to Tenant an estimate of the time necessary to repair the damage in question such that the Premises may be used by and accessible to Tenant and the Building and Common Areas
operable as a first-class office building; such notice will be based upon the review and opinions of Landlord’s architect and contractor (“Landlord’s Repair Notice”). If the damage is covered under insurance
pursuant to the provisions of the foregoing Paragraph 21 (or any other insurance Landlord may then be carrying), Landlord shall restore such damage provided that: (i) the insurance proceeds, plus the amount of any deductible (the payment of
which shall be Tenant’s responsibility), are sufficient to pay all of the cost of restoration without the necessity of Landlord paying any additional cost of such repairs; and (ii) in the reasonable judgment of Landlord, the restoration
can be completed within two hundred seventy (270) days after the date of the damage or casualty under the laws and regulations of the state, federal, county and municipal authorities having jurisdiction. If such conditions apply so as to
require Landlord to restore such damage pursuant to this Paragraph, this Lease shall continue in full force and effect, subject to Tenant’s rights as described below, unless otherwise agreed to in writing by Landlord and Tenant. Tenant shall be
entitled to a proportionate reduction of Monthly Basic Rent at all times during which Tenant’s use of the Premises is interrupted, such proportionate reduction to be based on the extent to which the damage and restoration efforts actually
interfere with Tenant’s access to or use of business in the Premises (which Landlord expressly acknowledges may be a circumstance in which the Premises are not damaged but the Building Systems are substantially damaged so as to render the
Premises unusable or inaccessible to Tenant). Tenant’s right to a reduction of rent hereunder shall be Tenant’s sole and exclusive remedy in connection with any such damage. 

22.2 In the event that the Building is damaged by a casualty, and Landlord is not required to restore such damage in accordance with the
provisions of the immediately preceding Paragraph, Landlord shall have the option to either (i) repair or restore such damage, with the Lease continuing in full force and effect (subject to Tenant’s rights as described below), but Monthly
Basic Rent to be proportionately abated as provided above; or (ii) give notice to Tenant at any time within forty-five (45) days after the occurrence of such damage terminating this Lease as of a date to be specified in such notice which
date shall not be less than thirty (30) nor more than sixty (60) days after the date on which such notice of termination is given. In the event of the giving of such notice of termination, this Lease shall expire and all interest of Tenant
in the Premises shall terminate on the date so specified in such notice and the Monthly Basic Rent, reduced by any proportionate reduction in Monthly Basic Rent as provided for above, shall be paid to the date of such termination. Notwithstanding
the foregoing, if Landlord elects to 

  
 36 

 
terminate this Lease pursuant to this Paragraph, if within thirty (30) days after receipt of Landlord’s notice Tenant elects to provide the funds necessary to make up the shortage (or
absence) of insurance proceeds and provides Landlord with reasonable assurance thereof, Landlord shall restore the Building as provided in this Paragraph provided that the Building is reasonably subject to restoration within one hundred eighty
(180) days following the date on which the casualty occurs. 
 22.3 If the Premises are damaged by fire or other casualty and are
rendered not reasonably usable for Tenant’s business purposes thereby, or if the Building shall be so damaged that Tenant shall be deprived of reasonable access to the Premises, and if, pursuant to Landlord’s Repair Notice, the restoration
shall not be substantially completed on or before the date which is nine (9) months following the date of such damage or destruction, Tenant shall have the right to terminate this Lease by giving written notice (the “Termination
Notice”) to Landlord not later than thirty (30) days following receipt of Landlord’s Repair Notice. If Tenant gives a Termination Notice, this Lease shall be deemed cancelled and terminated as of the date of the damage, and Rent
shall be apportioned and shall be paid or refunded, as the case may be up to and including the date of such damage or destruction. Notwithstanding the foregoing, if Tenant was entitled to but elected not to exercise its right to terminate this Lease
and Landlord does not substantially complete the repair and restoration of the Premises within two (2) months after the expiration of the estimated period of time set forth in Landlord’s Repair Notice, which period shall be extended to the
extent of any delays caused by Tenant, then Tenant may terminate this Lease by written notice to Landlord within thirty (30) days after the expiration of such period, as the same may be so extended. 

22.4 Notwithstanding the foregoing, either Landlord or Tenant may terminate this Lease if the Building is damaged by fire or other casualty
(and the reasonably estimated cost of restoration of the Building exceeds twenty percent (20%) of the then replacement value of the Building) and such damage or casualty occurs during the last twelve (12) months of the Term of this Lease
(or the Term of the Extended Term, if applicable) by giving the other written notice thereof at any time within thirty (30) days following the occurrence of such damage or casualty. Such notice shall specify the date of such termination, which
date shall not be less than thirty (30) nor more than sixty (60) days following the date on which such notice of termination is given. In the event of the giving of such notice of termination, this Lease shall expire and all interest of
Tenant in the Premises shall terminate on the date so specified in such notice and the Rent shall be paid to the date of such termination. Notwithstanding the foregoing to the contrary, Landlord shall not have the right to terminate this Lease if
damage or casualty occurs during the last twelve (12) months of the Term if Tenant timely exercises the Extension Option within twenty (20) days after the date of such damage or casualty. 

22.5 Upon any termination of this Lease under any of the provisions of this Paragraph, the parties shall be released thereby without further
obligation to the other from the date possession of the Premises is surrendered to Landlord, except for (i) items which have already accrued and are then unpaid by either Tenant or Landlord under the Lease, (ii) any prepaid (and unearned)
Monthly Basic Rent or unused security deposit amounts, and (iii) any amount owed by either Tenant or Landlord to the other under the Work Letter. 

  
 37 

 22.6 In connection with Landlord’s performance of its obligation to rebuild, Tenant will not
unreasonably withhold, delay or defer its consent to modifications to the Tenant Improvements or the Building proposed by Landlord, provided that such modifications do not increase the obligations of Tenant hereunder or adversely affect
Tenant’s use of the Premises. The repair and restoration of Tenant’s personal property and trade fixtures, shall be the obligation of Tenant. 

22.7 Tenant hereby waives California Civil Code Sections 1932(2) and 1933(4), providing for termination of hiring upon destruction of the
thing hired and Sections 1941 and 1942, providing for repairs to and of premises. 
 23. Eminent Domain. 

23.1 In case the whole of the Premises, or such part thereof as shall substantially interfere with Tenant’s use and occupancy thereof,
shall be taken for any public or quasi-public purpose by any lawful power or authority by exercise of the right of appropriation, condemnation or eminent domain, or sold to prevent such taking, either party shall have the right to terminate this
Lease effective as of the date possession is required to be surrendered to said authority. Tenant shall not assert any claim against Landlord or the taking authority for any compensation because of such taking (provided that Tenant may present a
separate claim for Tenant’s relocation costs and lost personal property, so long as such claim does not diminish any award otherwise available to Landlord), and Landlord shall be entitled to receive the entire amount of any award without
deduction for any estate or interest of Tenant. In the event the amount of property or the type of estate taken shall not substantially interfere with the conduct of Tenant’s business, Landlord shall be entitled to the entire amount of the
award without deduction for any estate or interest of Tenant. If this Lease is not so terminated, Landlord shall promptly proceed to restore the Premises to substantially their same condition prior to such partial taking, and a proportionate
allowance shall be made to Tenant for the rent corresponding to the time during which, and to the part of the Premises of which, Tenant shall be so deprived on account of such taking and restoration. Nothing contained in this Paragraph shall be
deemed to give Landlord any interest in any award separately made to Tenant for the taking of personal property and trade fixtures belonging to Tenant or for moving costs incurred by Tenant in relocating Tenant’s business. Landlord and Tenant
hereby agree that if Landlord is obligated to repair or restore the Premises pursuant to this Paragraph 23.1, Landlord shall be obligated to make such repairs or restoration only of those portions of the Premises which were originally provided at
Landlord’s expense (including the Tenant Improvements) and only to the extent of any award amount received by Landlord. 
 23.2 In the
event of taking of the Premises or any part thereof for temporary use, (i) this Lease shall be and remain unaffected thereby and rent shall not abate, and (ii) Tenant shall be entitled to receive for itself such portion or portions of any
award made for such use with respect to the period of the taking which is within the Term, provided that if such taking shall remain in force at the expiration or earlier termination of this Lease, Tenant shall then pay to Landlord a sum equal to
the reasonable cost of performing Tenant’s obligations under Paragraph 32 with respect to surrender of the Premises and upon such payment shall be excused from such obligations. For purpose of this Paragraph 23.2, a temporary taking shall be
defined as a taking for a period of 270 days or less. 

  
 38 

 23.3 Landlord and Tenant each hereby waive the provisions of California Code of Civil Procedure
Section 1265.130 and any other applicable existing or future law, ordinance or governmental regulation providing for, or allowing either party to petition the courts of the state of California for, a termination of this Lease upon a partial
taking of the Premises and/or the Building. 
 24. Bankruptcy. If Tenant shall file a petition in bankruptcy under any chapter of federal
bankruptcy law as then in effect, or if Tenant be adjudicated a bankrupt in involuntary bankruptcy proceedings and such adjudication shall not have been vacated within ninety (90) days from the date thereof, or if a receiver or trustee be
appointed of Tenant’s property and the order appointing such receiver or trustee not be set aside or vacated within ninety (90) days after the entry thereof, or if Tenant shall assign Tenant’s estate or effects for the benefit of
creditors, or if this Lease shall otherwise by operation of law pass to any person or persons other than Tenant, then in any such event Landlord may, if Landlord so elects, with or without notice of such election and with or without entry or action
by Landlord, forthwith terminate this Lease. Notwithstanding any other provisions of this Lease, Landlord, in addition to any and all rights and remedies allowed by law or equity, shall upon such termination be entitled to recover damages in the
amount provided in Paragraph 25.2 below. In the event of such termination, neither Tenant nor any person claiming through or under Tenant or by virtue of any statute or order of any court shall be entitled to possession of the Premises, and Tenant
shall forthwith quit and surrender the Premises to Landlord. Nothing herein contained shall limit or prejudice the right of Landlord to prove and obtain as damages by reason of any such termination an amount equal to the maximum allowed by any
statute or rule of law in effect at the time when, and governing the proceedings in which, such damages are to be proved, whether or not such amount be greater, equal to, or less than the amount of damages recoverable under the provisions of this
Paragraph 24. 
 25. Defaults and Remedies. 

25.1 The occurrence of any one or more of the following events shall constitute a Default hereunder by Tenant: 

(a) The abandonment of the Premises by Tenant, as provided by the California Civil Code. 

(b) The failure of Tenant to make any payment of Monthly Basic Rent or Common Operating Expenses or Direct Operating Expenses to be made by
Tenant hereunder within three (3) business days following notice from Landlord that the same is past due. 
 (c) The failure by Tenant
to make any payment of rent or any other payment required to be made by Tenant hereunder other than Monthly Basic Rent, Common Operating Expenses or Direct Operating Expenses as and when due, where such failure continues for a period of five
(5) days after written notice thereof from Landlord to Tenant; provided, however, that any such notice shall be in lieu of, and not in addition to, any notice required under California Code of Civil Procedure 1161. 

  
 39 

 (d) The failure by Tenant to observe or perform any of the express or implied covenants or
provisions of this Lease to be observed or performed by Tenant, other than as specified in Paragraph 25.1(b) or 25.1(c) above, where such failure shall continue for a period of thirty (30) days after written notice thereof from Landlord to
Tenant; provided, however, that any such notice shall be in lieu of, and not in addition to, any notice required under California Code of Civil Procedure 1161; provided, further, that if the nature of Tenant’s default is such that more than
thirty (30) days are reasonably required for its cure, then Tenant shall not be deemed to be in default if Tenant shall commence such cure within said thirty (30) day period and thereafter diligently and without interruption prosecute such
cure to completion following the written notice from Landlord pursuant to this Paragraph. 
 (e) (1) The making by Tenant of any general
assignment for the benefit of creditors; (2) the filing by or against Tenant of a petition to have Tenant adjudged a bankrupt or a petition for reorganization or arrangement under any law relating to bankruptcy (unless, in the case of a
petition filed against Tenant, the same is dismissed within ninety (90) days); (3) the appointment of a trustee or receiver to take possession of substantially all of Tenant’s assets located at the Premises or of Tenant’s
interest in this Lease, where possession is not restored to Tenant within ninety (90) days; or (4) the attachment, execution or other judicial seizure of substantially all of Tenant’s assets located at the Premises or of Tenant’s
interest in this Lease where such seizure is not discharged within ninety (90) days. 
 25.2 In the event of any such Default by
Tenant, in addition to any other remedies available to Landlord at law or in equity, Landlord shall have the immediate option to terminate this Lease and all rights of Tenant hereunder. Upon such termination of Tenant’s right to possession of
the Premises, this Lease shall terminate and Landlord shall be entitled to recover damages from Tenant as provided in California Civil Code Section 1951.2 or any other applicable existing or future law, ordinance or regulation providing for
recovery of damages for such breach (but not consequential damages except as provided in Civil Code Section 1951.2), including but not limited to the following: 

(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 that 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 his
obligations under this Lease or which in the ordinary course of things would be likely to result therefrom. 
 As used in Paragraphs 25.2(a)
and 25.2(b) above, the “worth at the time of award” is computed by allowing interest at the maximum rate permitted by law per annum. As used in 

  
 40 

 
Paragraph 25.2(c) above, the worth at the time of awards is computed by discounting to present value at the time of the award such amount at the discount rate of the Federal Reserve Bank of San
Francisco at the time of award plus one percent (1%). 
 25.3 If a Default exists under this Lease, Landlord may exercise its rights under
California Civil Code Section 1951.4 and may continue this Lease in effect after Tenant has breached this Lease and abandoned the Premises and Landlord may recover rent as it becomes due; provided, however that Tenant has the right to sublet or
assign tins Lease, subject to reasonable limitations. Acts of maintenance or preservation or efforts to relet the Premises or the appointment of a receiver upon initiative of Landlord to protect Landlord’s interest under this Lease shall not
constitute a termination of Tenant’s right to possession. 
 25.4 During the continuance of a Default, Landlord may enter the Premises
without terminating this Lease and remove all of Tenant’s personal property, and any of Tenant’s trade fixtures from the Premises and store them at Tenant’s risk and expense. If Landlord removes such property from the Premises and
stores it at Tenant’s risk and expense, and if Tenant fails to pay the cost of such removal and storage after written demand therefor and/or to pay any rent then due, then after the property has been stored for a period of thirty (30) days
or more Landlord may sell such property at public or private sale, in the manner and at such times and places as Landlord deems commercially reasonable Landlord shall provide reasonable notice to Tenant of the time and place of such sale. The
proceeds of any such sale shall be applied first to the payment of the expenses for removal and storage of the property, the preparation for and the conducting of such sale, and for attorneys’ fees and other legal expenses incurred by Landlord
in connection therewith; and the balance shall be applied to any past due amount owing hereunder. Tenant hereby waives all claims for damages that may be caused by Landlord’s re-entering and taking possession of the Premises or removing and
storing Tenant’s personal property pursuant to this Paragraph 25, except to the extent the same arise out of the gross negligence or willful misconduct of Landlord or Landlord’s employees or contractors and Tenant shall hold Landlord
harmless from and against any loss, cost or damages resulting from any such act. No re-entry by Landlord shall constitute or be construed to be a forcible entry by Landlord. 

25.5 All rights, options’ and remedies of Landlord contained in this Lease shall be construed and held to be cumulative, and no one of
them shall be exclusive of the other, and Landlord shall have the right to pursue any one or all of such remedies or any other remedy or relief which may be provided by law, whether or not stated in this Lease. No waiver of any Default of Tenant
hereunder shall be implied from any acceptance by Landlord of any rent or other payments due hereunder or any omission by Landlord to take any action on account of such Default if such Default persists or is repeated, and no express waiver shall
affect Defaults other than as specified in said waiver. The consent or approval or Landlord to or of any act by Tenant requiring Landlord’s consent or approval shall not be deemed to waive or render unnecessary Landlord’s consent or
approval to or of any subsequent similar acts by Tenant. 
 25.6 Landlord shall not be in default unless Landlord fails to perform
obligations required of Landlord within a reasonable time, but in no event later than thirty (30) days after notice by Tenant to Landlord specifying the nature of the obligation Landlord has failed to perform; provided, however, that if the
nature of Landlord’s obligation is such that more than thirty (30) days are required for performance, then Landlord shall not be in default if Landlord 

  
 41 

 
commences performance within such thirty (30) day period and thereafter diligently prosecutes the same to completion. Tenant shall not have the right based upon a default of Landlord to
terminate this Lease or to withhold, offset or abate rent. Tenant’s sole recourse for Landlord’s default being an action for damages against Landlord arising out of Landlord’s default and/or for injunctive relief or declaratory
judgment. Tenant shall not have the right to terminate this Lease or to withhold, offset or abate the payment of rent based upon the unreasonable or arbitrary withholding by Landlord of its consent or approval of any matter requiring Landlord’s
consent or approval, including, but not limited to, any proposed assignment or subletting, Tenant’s remedies in such instance being limited to a declaratory relief action, specific performance, injunctive relief or an action for actual damages.
Tenant shall not in any case be entitled to any consequential (including lost profits) or punitive damages based upon any Landlord default or withholding of consent or approval. Notwithstanding anything to the contrary contained in this Lease,
Tenant agrees and understands that Tenant shall look solely to the estate and property of Landlord in the Building (which shall be deemed to include the rental income at the Building, the proceeds of any sale of all or any portion of the Building by
Landlord as well as any insurance or condemnation proceeds), for the enforcement of any judgment (or other judicial decree) requiring the payment of money by Landlord to Tenant by reason of any default or breach by Landlord in the performance of its
obligations under this Lease, it being intended hereby that no other assets of Landlord or any of Landlord’s affiliates shall be subject to levy, execution, attachment or any other legal process for the enforcement or satisfaction of the
remedies pursued by Tenant in the event of such default or breach. 
 26. Assignment and Subletting. Except in connection with a
“Permitted Transfer” or a “Desk License” (as each term is defined below) Tenant shall not voluntarily assign, hypothecate or encumber its interest in this Lease or in the Premises, or sublease all or any part of the
Premises, or allow any other person or entity to occupy or use all or any part of the Premises, (each a “Transfer”), without first obtaining Landlord’s prior written consent, which consent shall not be unreasonably withheld,
conditioned or delayed. Any Transfer without Landlord’s prior written consent shall be voidable, at Landlord’s election, and shall constitute a Default if not rescinded within five (5) business days following notice from Landlord. No
consent to any Transfer shall constitute a further waiver of the provisions of this Paragraph. No later than thirty (30) days prior to the effective date of a proposed Transfer other than a Permitted Transfer, Tenant shall notify Landlord in
writing of Tenant’s intent to Transfer (“Transfer Notice”), the name of any proposed assignee or sublessee, information concerning the financial responsibility of the proposed assignee or sublessee and the terms of the proposed
Transfer, and Landlord shall, within thirty (30) days of receipt of such written notice as well as any additional information reasonably requested by Landlord concerning any proposed assignee’s or sublessee’s financial responsibility,
elect one of the following: 
 (a) Consent to such proposed Transfer; 

(b) Refuse such consent, which refusal shall be on reasonable grounds, including but not limited to those matters set forth herein below; 

  
 42 

 (c) If Landlord fails to timely deliver to Tenant notice of Landlord’s consent, or the
withholding of consent, to a proposed Transfer, Tenant may send a second (2nd) notice to Landlord, which notice must contain the following inscription, in bold faced lettering: 

“SECOND NOTICE DELIVERED PURSUANT TO PARAGRAPH 26 OF LEASE — FAILURE TO TIMELY RESPOND WITHIN FIVE (5) BUSINESS DAYS SHALL
RESULT IN DEEMED APPROVAL OF TRANSFER.” If Landlord fails to deliver notice of Landlord’s consent to, or the withholding of Landlord’s consent, to the proposed Transfer within such five (5) business day period, Landlord shall
be deemed to have approved the Transfer in question. If Landlord at any time timely delivers notice to Tenant of Landlord’s withholding of consent to a proposed Transfer, Landlord shall specify in reasonable detail in such notice, the basis for
such withholding of consent. 
 Notwithstanding anything to the contrary contained in this Paragraph 26, in the event Tenant contemplates an
assignment or a sublease of 50% or more of the Premises for all or substantially all of the remaining Lease Term, in each case except in the event of a Permitted Transfer, Tenant shall, in addition to the Transfer Notice, give Landlord notice (the
“Intention to Transfer Notice”) of such contemplated Transfer (whether or not the contemplated Transferee or the terms of such contemplated Transfer have been determined). The Intention to Transfer Notice shall specify the portion
of and amount of rentable square feet of the Premises which Tenant intends to Transfer (the “Contemplated Transfer Space”), the contemplated date of commencement of the contemplated Transfer (the “Contemplated Effective
Date”), and the contemplated length of the term of such contemplated Transfer, and shall specify that such Intention to Transfer Notice is delivered to Landlord pursuant to this Paragraph 26 in order to allow Landlord to elect to recapture
the Contemplated Transfer Space for the entire remaining Term of this Lease. Thereafter, Landlord shall have the option, by giving written notice to Tenant within twenty (20) days after receipt of any Intention to Transfer Notice, to recapture
the Contemplated Transfer Space. Such recapture shall cancel and terminate this Lease with respect to the Contemplated Transfer Space as of the date stated in the Intention to Transfer Notice as the effective date of the proposed Transfer. Such
recapture of the Contemplated Transfer Space by Landlord shall cancel and terminate this Lease with respect to the Contemplated Transfer Space for the remaining Term of this Lease and Tenant shall be relieved of its obligation under this Lease with
respect to the Contemplated Transfer Space having been recaptured. In the event of a recapture by Landlord, if this Lease shall be canceled with respect to less than the entire Premises, the rent reserved herein shall be prorated on the basis of the
number of rentable square feet retained by Tenant in proportion to the number of rentable square feet contained in the Premises, and this Lease as so amended shall continue thereafter in full force and effect, and upon request of either party, the
parties shall execute written confirmation of the same. If Landlord declines, or fails to elect in a timely manner to recapture the Contemplated Transfer Space under this Paragraph 26, then, provided Landlord has consented to the proposed
Transfer, and not otherwise, Tenant shall be entitled to proceed to transfer the Contemplated Transfer Space to the proposed transferee. 

Without limiting the other instances in which it may be reasonable for Landlord to withhold its consent to an assignment or sublease, Landlord
and Tenant acknowledge that it shall be reasonable for Landlord to withhold its consent in the following instances: (i) if at the time consent is requested Tenant is in Default; (ii) in the case of a proposed assignment of Tenant’s
interest in this Lease, if the proposed assignee’s credit, character and business or professional standing does not meet the reasonable standards of Landlord; or (iii) if the proposed assignee is an existing tenant of the Building (unless
Landlord is not able to accommodate such existing tenant) or Landlord is currently actively marketing comparable space in the Building to such 

  
 43 

 
proposed assignee. Without limiting Other instances in which it may be reasonable for Landlord to withhold its consent to any encumbrance or hypothecation of the interest of Tenant in this Lease,
Landlord and Tenant acknowledge that is reasonable for Landlord to withhold its consent in instances where by reason of such encumbrance or hypothecation a tenant other than a tenant as approved by Landlord may acquire rights with respect to the
Premises or any portion of the Premises by reason of any default proceedings pursuant to any such encumbrance or hypothecation or otherwise. 

In the event that Landlord shall consent to any Transfer under the provisions of this Paragraph, Tenant shall pay Landlord’s reasonable
processing costs and attorneys’ fees incurred in giving such consent (not to exceed $2,500). Landlord’s consent to any Transfer, including without limitation in connection with a Permitted Transfer, shall not release or relieve Tenant from
its obligations for the full and timely performance of each and every term and condition to be performed by Tenant hereunder. If for any proposed assignment or sublease Tenant receives rent or other consideration, either initially or over the term
of the assignment or sublease, in excess of the rent and monthly amortization of Transfer Costs (defined below) called for hereunder, or, in case of the sublease of a portion of the Premises, in excess of the monthly amortization of all Transfer
Costs and such rent fairly allocable to such portion, after appropriate adjustments to assure that all other payments called for hereunder are taken into account, Tenant shall, except where such assignee or subtenant is an affiliate of Tenant, pay
to Landlord as additional rent hereunder 75% of the excess of each such payment of rent or other consideration received by Tenant promptly after its receipt. As used herein, “Transfer Costs” shall mean commercially reasonable
brokerage commissions, marketing costs, attorneys’ fees, and reasonable tenant improvement costs (or improvement allowances), incurred by Tenant in connection with such assignment or sublease, such Transfer Costs to be amortized for the
purposes of Tenant’s recovery of same from excess consideration, on a straight-line basis without interest over the then remaining Term of this Lease as of the effective date of such assignment or subletting. Landlord’s waiver or consent
to any assignment or subletting shall not relieve Tenant from any obligation under this Lease. 
 (d) Notwithstanding anything to the
contrary contained in this Lease, Tenant may assign this Lease or sublet the Premises, or any portion thereof, without Landlord’s consent, to any (i) entity which controls, is controlled by, or is under common control with Tenant;
(ii) any entity which results from a merger of, reorganization of, or consolidation with Tenant; or (iii) any entity which acquires substantially all of the stock or assets of Tenant, as a going concern, with respect to the business that
is being conducted in the Premises provided that, with respect to clauses (ii) and (iii) above, the assignee or sublessor as the case may be has a net worth greater than or equal to that of the Tenant at the commencement of the Term of
this Lease (hereinafter each a “Permitted Transfer”). In addition, a sale or transfer of the capital stock of Tenant shall be deemed a Permitted Transfer if (1) such sale or transfer occurs in connection with any bona
fide financing or capitalization for the benefit of Tenant, or (2) Tenant becomes a publicly traded corporation. Landlord shall have no right to terminate the Lease in connection with, and shall have no right to any sums or other economic
consideration resulting from, any Permitted Transfer. Tenant shall give Landlord at least thirty (30) days prior written notice of any proposed Permitted Transfer (unless such prior notice is precluded by applicable law, in which event Tenant
will provide such notice as soon as permitted) and shall provide to Landlord such information as Landlord may reasonably request with respect to the proposed Permitted Transfer. 

  
 44 

 (e) Landlord acknowledges that Tenant may, from time to time, have vendors, clients or
consultants performing work on behalf of Tenant occupy one or more desks or offices within the Premises on a temporary basis (and, for such purpose, Tenant may request that said individuals be issued Building access cards) but that such temporary
“desk-sharing” shall not constitute a Transfer hereunder so long as Tenant does not separately demise any space so occupied by such individuals or entities. Any such arrangement is referred to herein as a “Desk License”,
and the licensee under a Desk License, a “License Holder”. However, Tenant may not devote more than ten percent (10%) of the rentable area of the Premises to Desk Licenses. Tenant shall give written notice to Landlord at
least five (5) business days prior to the date on which any individual becomes a License Holder which notice shall identify the individual, provide a brief description of the individual’s relationship to Tenant and provide such other
information as Landlord may reasonably request. Each individual participating a License Holder shall be subject to the prior written approval of Landlord which approval shall not be unreasonably withheld, conditioned or delayed. 

27. Quiet Enjoyment. Landlord covenants and agrees with Tenant that upon Tenant paying the rent required under this Lease and paying all other
charges and performing all of the covenants and provisions aforesaid on Tenant’s part to be observed and performed under this Lease and subject to the terms and conditions of this Lease, Tenant shall and may peaceably and quietly have, hold and
enjoy the Premises in accordance with this Lease. 
 28. Subordination, Non-disturbance and Attornment. Landlord represents to Tenant that, as
of the Effective Date, there is no mortgage or deed of trust encumbering the Premises. Tenant agrees that if any loan is subsequently obtained by Landlord to be secured by the Site, Building and/or Premises, upon request Tenant shall agree to
subordinate this Lease to the lien of such mortgage or deed of trust pursuant to, and subject to, the provisions of this Paragraph 28. Tenant agrees that in the event that any future mortgage or deed of trust is foreclosed or a conveyance in lieu of
foreclosure is made for any reason, Tenant shall, if requested by the mortgagee or beneficiary, as applicable, agree in writing to attorn to and become the Tenant of the successor in interest to Landlord provided that in all events Tenant’s
rights under this Lease shall not be affected absent any uncured Default by Tenant. Tenant covenants and agrees to execute (or make good faith comments to and thereafter execute) and deliver, upon request by Landlord and in the form reasonably
requested by Landlord, any additional documents evidencing the subordination of this Lease with respect to any such future mortgage or deed of trust, provided that such documents shall confirm that Tenant’s leasehold interest and any offset
rights of Tenant expressly set forth in this Lease, shall not be terminated or otherwise affected as a result of such financing or any exercise by lender of any rights against Landlord or the Premises thereunder. 

29. Estoppel Certificate. 
 29.1
Within ten (10) business days following any written request which Landlord or Tenant (“Requesting Party”) may make from time to time, Tenant or Landlord, as applicable (“Responding Party”) shall execute and
deliver to Requesting Party a statement, in a form acceptable to Requesting Party, certifying; (i) the Lease Commencement Date; (ii) the fact that

this Lease is unmodified and in full force and effect (or, if there have been modifications hereto, that this Lease is in full force and effect, as modified, and stating the date and nature of
such modifications); (iii) the date to which the rental and other sums payable under this Lease have been paid; (iv) the fact that to the knowledge of the Responding Party, there are no current defaults under this Lease by either Landlord
or Tenant except as specified in such statement; and (v) such other matters reasonably requested by the Requesting Party. Landlord and Tenant intend that any statement delivered pursuant to this Paragraph 29 may be relied upon by any
prospective mortgagee, beneficiary, purchaser, assignee or subtenant of the Premises or any interest therein or any auditor of either Landlord or Tenant. 

29.2 The Responding Party’s failure to deliver such statement within such time shall be conclusive upon Responding Party (i) that
this Lease is in full force and effect, without modification except as may be represented by Requesting Party, (ii) that there are no known uncured defaults in the Requesting Party’s performance, and (iii) that not more than one
(1) month’s rent has been paid in advance. 
 30. Conflict of Laws. This Lease shall be governed by and construed pursuant to the
laws of the State of California. 
 31. Successors and Assigns. Except as otherwise provided in this Lease, all of the covenants, conditions
and provisions of this Lease shall be binding upon and shall inure to the benefit of the parties hereto and their respective heirs, personal representative, successors and assigns. 

32. Surrender of Premises. The voluntary or other surrender of this Lease by Tenant, or a mutual cancellation thereof, shall not work a merger,
and shall, at the option of Landlord, operate as an assignment to it of any or all subleases or subtenancies. Upon the expiration or termination of this Lease, Tenant shall peaceably surrender the Premises and all alterations and additions thereto
broom-clean, in good order, repair and condition, reasonable wear and tear and damage for which Tenant is not liable excepted. Further, upon expiration or termination of this Lease, Tenant, at its cost, shall restore the Premises, as required by the
provisions of Section 14.1(g) and as otherwise required by the provisions of this Lease including, without limitation, the provisions of Paragraph 14.7. The delivery of keys to any employee of Landlord or to Landlord’s agent or any
employee thereof shall not be sufficient to constitute a termination of this Lease or a surrender of the Premises. 
 33. Professional Fees.

 33.1 In the event that Landlord or Tenant should bring suit for the possession of the Premises, for the recovery of any sum due under
this Lease, or because of the breach of any provisions of this Lease, or for any other relief against Tenant or Landlord hereunder, or should either party bring suit against the other with respect to matters arising from or growing out of this
Lease, then all costs and expenses, including without limitation, its reasonable professional fees such as appraisers’, accountants’ and attorneys’ fees, incurred by the prevailing party therein shall be paid by the other party,
whether or not the action is prosecuted to judgment. 

  
 46 

 33.2 Should Landlord and/or any of the Landlord Parties be named as a defendant in any suit
brought against Tenant in connection with or arising out of Tenant’s occupancy hereunder, Tenant shall pay to Landlord and/or such Landlord Party its costs and expenses incurred in such suit as and when incurred, including without limitation,
its reasonable professional fees such as appraiser’s, accountants’ and attorneys’ fees. 
 34. Performance by Tenant. Except as
otherwise provided in this Lease, all covenants and agreements to be performed by Tenant under any of the terms of this Lease shall be performed by Tenant at Tenant’s sole cost and expense and without any abatement of rent. Tenant acknowledges
that the late payment by Tenant to Landlord of any sums due under this Lease will cause Landlord to incur costs not contemplated by this Lease, the exact amount of such cost being extremely difficult and impractical to fix. Such costs include,
without limitation, processing and accounting charges, and late charges that may be imposed on Landlord by the terms of any encumbrance and note secured by any encumbrance covering the Premises or the Building of which the Premises are a part.
Therefore if any amount due Landlord from Tenant hereunder has not been received on or before the date due, Tenant shall pay to Landlord, without notice or demand, as additional rent, four percent (4%) of the overdue amount as a late charge;
notwithstanding the foregoing to the contrary, Tenant shall be entitled to notice and a five (5) calendar day cure period prior to the imposition of such late charge on the first
(1st) occasion in any calendar year which any amount will by Tenant hereunder is not paid when due. Such overdue amount shall also bear interest, as additional rent, at the maximum rate
permissible by law calculated, as appropriate, from that date when due until the date of payment to Landlord (the “Interest Rate”). Landlord’s acceptance of any late charge or interest shall not constitute a waiver of
Tenant’s default with respect to the overdue amount or prevent Landlord from exercising any of the other rights and remedies available to Landlord under this Lease or any law now or hereafter in effect. 

35. Landlord’s Mortgagee and Senior Lessor Protection; Landlord Waiver and Consent Agreements in favor of Tenant’s Lenders. No default
hereunder on the part of Landlord which would entitle Tenant under the terms of this Lease, or by law, terminate this Lease (if any), shall result in a release of such obligations or a termination of this Lease unless (a) Tenant has given
notice to Landlord and to any beneficiary of a deed of trust or mortgage covering the Site and/or the Building (or any portion thereof) and to the lessor under any master or ground lease covering the Building, the Site or any interest
therein, in each case, whose identity and address shall have been furnished in writing to Tenant, and (b) Tenant offers such beneficiary, mortgagee or lessor a reasonable opportunity (but in no event less than thirty (30) days) to cure the
default, including time to obtain possession of the Premises by power of sale or of judicial foreclosure, if such should prove necessary to effect a cure (but only if the beneficiary, lender or mortgagee responds to Tenant’s notice within a
reasonable time confirming that such beneficiary, lender or mortgagee intends to cure the subject default). Landlord shall, from time to time, give Tenant written notice of the identity and address of the beneficiary of any deed of trust or mortgage
covering the Site and/or the Building (or any portion thereof) and/or the lessor under any master or ground lease. 
 36. Definition of
Landlord. The term “Landlord” as used in this Lease, so far as covenants or obligations on the part of Landlord are concerned, shall be limited to mean, and include only, the owner or owners, at the time in question, of the fee title
to, or a lessee’s interest in a ground 

  
 47 

 
lease of the Site or master lease of the Building. In the event of any transfer, assignment or other conveyance or transfer of any such title or interest, Landlord herein named (and in case of
any subsequent transfers or conveyances, the then grantor) shall be automatically freed and relieved from and after the date of such transfer, assignment or conveyance of all liability accruing thereafter with respect to the performance of any
covenants or obligations on the part of Landlord contained in this Lease thereafter to be performed and, without further agreement, the transferee of such title or interest shall be deemed to have agreed to observe and perform any and all
obligations of Landlord hereunder, during its ownership of the Site and Building (including the Premises). Landlord may transfer its interest in the Site and Building (including the Premises) without the consent of Tenant and such transfer or
subsequent transfer shall not be deemed a violation on Landlord’s part of any of the terms and conditions of this Lease. 
 37. Waiver. The
failure of Landlord or Tenant to seek redress for violation of, or to insist upon strict performance of, any term, covenant or condition of this Lease shall not be deemed a waiver of such violation or prevent a subsequent act which would have
originally constituted a violation from having all the force and effect of an original violation, nor shall any custom or practice which may become established between the parties in the administration of the terms hereof be deemed a waiver of, or
in any way affect, the right of Landlord or Tenant to insist upon the performance by Tenant or Landlord, as the case may be, in strict accordance with said terms. The subsequent acceptance or payment of rent hereunder by Landlord or Tenant shall not
be deemed to be a waiver of any preceding breach by Tenant or Landlord of any term, covenant or condition of this Lease, other than the failure of Tenant to pay the particular rent so accepted, regardless of Landlord’s knowledge of such
preceding breach at the time of acceptance of such rent. 
 38. Identification of Tenant. If more than one person executes this Lease as Tenant,
(a) each of them is jointly and severally liable for the keeping, observing and performing of all of the terms, covenants, conditions, provisions and agreements of this Lease to be kept, observed and performed by Tenant, and (b) the term
“Tenant” as used in this Lease shall mean and include each of them jointly and severally and the act of or notice from, or notice or refund to, or the signature of, any one or more of them, with respect to the tenancy or this Lease,
including, but not limited to, any renewal, extension, expiration, termination or modification of this Lease, shall be binding upon each and all of the persons executing this Lease as Tenant with the same force and effect as if each and all of them
had so acted or so given or received such notice or refund or so signed. 
 39. Terms and Headings. The words “Landlord” and
“Tenant” as used herein shall include the plural as well as the singular. Words used in any gender include other genders. The Paragraph headings of this Lease are not a part of this Lease and shall have no effect upon the construction or
interpretation of any part hereof. Terms capitalized but not otherwise defined herein shall have the respective meanings given to such terms in the Summary. Terms defined in the plural shall also include the singular and those defubed in the
singular shall also include the plural. 
 40. Examination of Lease. Submission of this instrument for examination or signature by Tenant does not
constitute a reservation of or option for Lease and it is not effective as a Lease or otherwise until execution by and delivery to both Landlord and Tenant. 

  
 48 

 41. Time. Time is of the essence with respect to the performance of every provision of this Lease in which
time or performance is a factor. 
 42. Prior Agreement; Amendments. This Lease contains all of the agreements of the parties hereto with respect to
any matter covered or mentioned in this Lease, and no prior agreement or understanding, oral or written, express or implied, pertaining to any such matter shall be effective for any purpose. No provision of this Lease may be amended or added to
except by an agreement in writing signed by the parties hereto or their respective successors in interest. The parties acknowledge that all prior agreements, representations and negotiations are deemed superseded by the execution of this Lease to
the extent they are not incorporated herein. 
 43. Severability. Any provision of this Lease which shall prove to be invalid, void or illegal in no
way affects, impairs or invalidates any other provision hereof, and such other provisions shall remain in full force and effect. 
 44. Recording.
Tenant shall not record this Lease nor a short memorandum thereof without the consent of Landlord and if such recording occurs, it shall be at the sole cost and expense of Tenant, including any documentary transfer taxes or other expenses related to
such recordation. 
 45. Limitation on Liability. The obligations of Landlord and Tenant under this Lease do not constitute personal obligations of
the individual partners, members, directors, officers or shareholders of Landlord or Tenant, and neither Landlord nor Tenant shall seek recourse against the individual partners, members, directors, officers or shareholders of Landlord or Tenant, or
any of their personal assets for satisfaction of any liability in respect to this Lease. In consideration of the benefits accruing hereunder, Tenant and all successors and assigns covenant and agree that in the event of any actual or alleged
failure, breach or default hereunder by Landlord, the sole and exclusive remedy shall be against Landlord’s interest in the Building (which shall be deemed to include the rental income at the Building, the proceeds of any sale of all or any
portion of the Building by Landlord as well as any insurance or condemnation proceeds). 
 46. Signs. Tenant shall have the right to place signage on
the exterior of the Building subject to Landlord’s reasonable consent as to size, location and style and subject to Tenant’s obtaining approval of the City of San Francisco and any applicable governmental agencies. All signs shall be
constructed, erected and affixed to the Building at Tenant’s sole cost and expense, and Tenant shall be responsible for the removal of such signage, and the repair of any damage to the Premises caused thereby, at the end of the Term. All signs
shall be in full compliance with all applicable ordinances, statutes and regulations imposed by all applicable governmental authorities. Landlord agrees to reasonably assist Tenant at no material cost to Landlord in obtaining governmental approval
of all Landlord approved signage. Tenant shall also be permitted to install signage in the lobby/ground floor entrance to the Building and in the elevator lobbies on all floors of the Building occupied by Tenant, subject to Landlord’s
reasonable consent and at Tenant’s cost. 
 47. Roof Space. Landlord shall, at no additional cost to Tenant, make roof space available for
Tenant’s rooftop equipment on the roof of the Building. All such equipment and its specifications and location shall be subject to Landlord’s reasonable prior written approval. 

  
 49 

 Tenant shall be responsible for the installation, maintenance, screening (as necessary) and removal of the
rooftop equipment as well as any repairs necessitated by any of the foregoing, at Tenant’s sole cost and expense. Tenant shall have, in addition, the exclusive right to use the deck area located on the roof of the Building. 

48. Fire Stairs. Tenant shall have the right, subject to Landlord’s approval, which shall not be unreasonably withheld, to utilize the fire stairs
for travel between floors occupied by Tenant, so long as such use is code complaint. Tenant may securitize the stairwell and make cosmetic alterations to the fire stairs, so long as such alterations are code complaint, and subject to receipt of
Landlord’s prior written consent. 
 49. Sky Bridge. The parties acknowledge that there is an existing sky-bridge(s) connected to the Building
with the building located at 301 Brannan Street, San Francisco, California (“Sky Bridge”). The Sky Bridge is currently closed and is not in use. As of the Effective Date, Tenant currently leases space at 301 Brannan Street. Landlord
and Tenant agree to use commercially reasonable good-faith efforts to obtain all required approvals to reopen the Sky Bridge including coordinating the same with the owner of 301 Brannan, Kilroy Realty, and the City of San Francisco. The parties
intend that the connection between the third floor of the Building and 301 Brannan be opened first and subsequently the connection between the second floor of the Building and 301 Brannan. Tenant agrees that all costs associated with such reopening
efforts including, without limitation, any subsequent construction, if required, shall be at Tenant’s sole cost and expense. Landlord makes no representation or warranty regarding the Sky Bridge or its condition. Tenant acknowledges that the
reopening of the Sky Bridge or any part thereof is not a condition precedent to the effectiveness of this Lease. Upon surrender of the Premises, at the election of Landlord, Tenant, at its cost, shall restore the Sky Bridge to its condition prior to
any improvements made by Tenant pursuant to this Paragraph 49. 
 50. Modification for Lender. If in connection with obtaining construction, interim
or permanent financing for the Site and/or Building (or any interest therein), the lender shall request reasonable modifications in this Lease as a condition to such financing, Tenant will not unreasonably withhold, delay or defer its consent
thereto, provided that such modifications do not increase the obligations of Tenant hereunder or adversely affect the leasehold interest hereby created or Tenant’s rights hereunder, and provided further that such modifications are essentially
ministerial in nature. 
 51. Accord and Satisfaction. No payment by Tenant or receipt by Landlord of a lesser amount than the rent payment herein
stipulated shall be deemed to be other than on account of the rent, nor shall any endorsement or statement on any check or any letter accompanying any check or payment as rent be deemed an accord and satisfaction and Landlord may accept such check
or payment without prejudice to Landlord’s right to recover the balance of such rent or pursue any other remedy provided in this Lease. Tenant agrees that each of the foregoing covenants and agreements shall be applicable to any covenant or
agreement either expressly contained in this Lease or imposed by any statute or at common law. 
 52. Financial Statements. If requested by Landlord
in connection with a potential sale or financing of the Site and/or the Building (or any interest therein), Tenant shall, upon fifteen (15) business days prior written notice from Landlord, and provided Landlord executes and delivers

  
 50 

 
to Tenant a nondisclosure agreement in a form reasonably satisfactory to Tenant, provide Landlord with Tenant’s last financial statement, year to date financial statements and, to the extent
prepared and existing, financial statements of the two (2) years prior to the current financial statement year for Tenant. Such statement shall be prepared in accordance with generally accepted accounting principles and, shall either be audited
by an independent certified public accountant or certified by an officer of Tenant. Landlord shall use commercially reasonable efforts to protect the confidentiality of any such statement and to request that any proposed buyer or lender similarly
treat the information contained in such statement as being confidential in nature, such that such information shall only be disclosed to the consultants, analysts or counsel as may be reasonably necessary in order to evaluate a potential purchase
of, or loan upon, the Site and/or the Building (or any interest thereof). 
 53. Tenant as Corporation. If Tenant executes this Lease as a legal
entity, then Tenant represents and warrants that (a) the individuals executing this Lease on Tenant’s behalf are duly authorized to execute and deliver this Lease on the entity’s behalf and (b) that this Lease is binding upon
Tenant in accordance with its terms. 
 54. No Partnership or Joint Venture. Nothing in this Lease shall be deemed to constitute Landlord and Tenant
as partners or joint venturers. It is the express intent of the parties hereto that their relationship with regard to this Lease be and remain that of landlord and tenant. 

55. Counterparts. This Lease may be executed in counterparts with the same effect as if both parties hereto had executed the same document, Both
counterparts shall be construed together and shall constitute a single lease.

 TENANT WORK LETTER 

634 Second Street, San Francisco, California 

This Tenant Work Letter (“Work Letter”) is entered into effective December 11, 2014, and shall set forth the terms and conditions
controlling the construction of certain Tenant Improvements and Compliance Work (all as defined below) to the Premises. Unless otherwise defined herein, all capitalized terms shall have the meanings ascribed to them in that certain Lease dated
December 11, 2014 between OKTA, Inc., a California corporation (“Tenant”), and SFI Real Estate Holdings, LLC, a Delaware limited liability company (“Landlord”) (the “Lease”). 

ARTICLE 1. 
 DELIVERY OF
THE PREMISES 
 1.1 Delivery of the Premises. On the Access Date, Landlord shall deliver the Premises to Tenant, and Tenant shall
accept the Premises from Landlord, in its presently existing, “as-is” condition subject to the terms of the Lease (including, without limitation, Landlord’s obligations to deliver the Building Systems in good working order and repair
and Landlord’s general maintenance obligations set forth in the Lease). Tenant acknowledges and agrees that Landlord shall have no obligation or responsibility except as set forth in this Work Letter and in the Lease to perform any work,
repairs, construction or improvements to the Premises in advance of Tenant’s occupation and possession of the Premises. Landlord shall have only those obligations of repair and maintenance with respect to the Premises and/or the Building as
specifically set forth in the Lease.

prepared by Huntsman Architectural Group in the form of an AutoCAD compatible drawing file (“Base Building Plans”) and will deliver to Tenant a complete and current copy of all rules, regulations, instructions and procedures
promulgated by Landlord with respect to design and/or construction within the Building (“Building Requirements”) to Architect (defined below).

 (a) Monthly Disbursements. On or before the thirtieth (30th) day of each calendar month, Tenant shall deliver to

shall include costs directly related to design, permit and application fees, licenses and taxes, and architectural fees, consulting fees, construction management fees, engineering and mechanical services and hard construction costs related to the
Compliance Work expressly approved by Landlord. 
 2.3.2 Compliance Cost Budget. Prior to commencement of construction of the Tenant
Improvements and Compliance Work and following the preparation of Final Working Drawings as provided in Article 3 below and receipt of bids from subcontractors with respect to construction of the Compliance Work, Landlord and Tenant shall meet and
confer to determine a comprehensive budget for the Compliance Costs including a detailed list of Compliance Work and Compliance Cost Items (the “Compliance Cost Budget”). To the extent any component of Compliance Work is
combined with or connected closely to elements or components of the Tenant Improvements that are not directly related to Compliance Work, the Architect shall present a proposal detailing Architect’s good faith estimate of the percentage of work
attributable directly to Compliance Work and the corresponding Compliance Costs; provided however, all such proposals shall be subject to Landlord’s approval in its discretion. Upon reaching agreement regarding the Compliance Cost Budget,
Landlord and Tenant shall execute and date the final approved Compliance Cost Budget which shall establish the maximum amount of Compliance Costs for which the Landlord is responsible during the course of construction of the Compliance Work, except
as set forth herein to the contrary. However, as construction continues, if and to the extent that Tenant submits a Drawing Change Notice reflecting a Tenant Change in the Compliance Work, which Tenant Change is approved by Landlord (Landlord’s
approval not to be unreasonably withheld, conditioned or delayed), the Compliance Cost Budget shall be appropriately adjusted to account for such Tenant Change. Notwithstanding the immediately preceding sentence, the adjustments to the Compliance
Cost Budget shall be limited to those adjustments required by reason of changes to the Approved Working Drawings necessitated to comply with building codes or other applicable governmental requirements to the

  
 A-7 

 
extent attributable to Compliance Costs incurred in connection with any such changes and although Landlord may approve a Tenant Change relating to other modifications to the Approved Working
Drawings, increases in Compliance Costs relating to such Tenant Changes shall be added to the Compliance Cost Budget only to the extent approved by Landlord in its discretion. In the event that Landlord and Tenant are unable to agree on the maximum
amount of Compliance Costs for which Landlord is responsible within ten (10) business days following completion of the Final Working Drawings and receipt of all bids for the Compliance Work, either Landlord or Tenant shall be entitled to submit
the dispute to JAMS or its successor for mediation or if the matter is not resolved through mediation, then it shall be submitted to JAMS, or its successor, for final and binding arbitration to establish the cost of the Compliance Work. Either
Landlord or Tenant may commence mediation by providing to JAMS and the other party a written request for mediation. The selection of the mediator and/or arbitrator and the process for mediation or arbitration shall be as established by JAMS and the
cost of any mediation or arbitration shall be paid equally by Landlord and Tenant. The mediation, and if necessary, the arbitration shall be held in San Francisco and shall proceed as quickly as reasonably possible. The decision of Landlord and
Tenant as a result of the mediation or the decision of the arbitrator as a result of any arbitration with respect to the cost of the Compliance Work shall establish the maximum Compliance Cost. 

Tenant shall diligently construct the Compliance Work and will perform such work in accordance with the Compliance Cost Budget, as the same
may be adjusted. 
 2.3.3 Disbursement of the Compliance Costs. Landlord shall make monthly disbursements to Tenant of the Compliance
Costs as follows: 
 (a) Monthly Disbursements. On or before the thirtieth (30th) day of each calendar month, Tenant shall

(b) Other Terms. Landlord shall be obligated to make disbursements up to the aggregate amount of the Compliance Cost Budget (as the
same may be adjusted) as and when costs are incurred by Tenant for Compliance Cost Items included in the Compliance Cost Budget (as the same may be adjusted), based upon invoices submitted by Tenant for such costs. Landlord shall only be required to
make a progress payment provided that Tenant delivers lien releases for all work which is the subject of the payment request (conditioned on payment only) and unconditional lien releases for all Compliance Work completed prior to the Compliance Work
included within the scope of the subject progress payment. Landlord shall further have the right to confirm that all payments made through the date of the subject progress payment reasonably correspond to the completion percentage of the Compliance
Work and Landlord shall be entitled to require that Architect from time to time certify to Landlord the percentage of completion then having been achieved with respect to construction of the Compliance Work.

and/or Compliance Work, and in form and with companies as are required of Tenant pursuant to the terms of the Lease. 
 (ii) Special
Coverages. During construction of the Tenant Improvements, Tenant shall carry, or shall require Contractor to carry, “Builder’s All Risk” insurance in an amount reasonably approved by Landlord (but in no event greater than 100% of the
completed insurable value of the Tenant Improvements and Compliance Work) covering the construction of the Tenant Improvements and Compliance Work (at Tenant’s option, Contractor will carry such Builder’s All Risk insurance), and such
other insurance as Landlord may reasonably require, it being understood and agreed that the Tenant Improvements and Compliance Work shall be insured by Tenant pursuant to the Lease immediately upon completion thereof. Such insurance shall be in
amounts and shall include such extended coverage endorsements as may be reasonably required by Landlord including, but not limited to, the requirement that all of Tenant’s Agents shall carry excess liability and Products and Completed Operation

(other than Workers’ Compensation coverage) shall insure Tenant, and Landlord as an additional insured, as well as Contractor and Tenant’s Agents. 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 Landlord and that any other insurance maintained by Landlord is excess and noncontributing with

disapprove any portion of the Tenant Improvements and Compliance Work, Landlord shall promptly notify Tenant in writing of such disapproval and shall specify the items disapproved. Any defects or deviations in, and/or timely disapproval by Landlord
of, the Tenant Improvements and Compliance Work shall be rectified by Tenant, provided, however, that in the event Landlord reasonably determines that a defect or deviation exists or disapproves of any matter in connection with any portion of the
Tenant Improvements and Compliance Work and such defect, deviation or matter might adversely affect the Building Systems, the structure or exterior appearance of the Building or any other tenant’s use of such other tenant’s leased
premises, Landlord shall inform Tenant in writing and Tenant shall have five (5) business days to rectify same. In the event Tenant fails to do so, Landlord may take such action as Landlord deems reasonably 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 Tenant Improvements and Compliance Work
until such time as the defect, deviation and/or matter is corrected to Landlord’s satisfaction. Landlord shall perform any such correction in a diligent and timely manner so as to minimize any delay in the construction of the Tenant
Improvements and Compliance Work.

completion of construction of the Tenant Improvements and Compliance Work, Tenant shall cause a Notice of Completion to be recorded in the office of the Recorder of the County of San Francisco in accordance with Section 8182 of the Civil Code
of the State of California or any successor statute, and shall furnish a copy thereof to Landlord upon such recordation. If Tenant fails to do so, Landlord may execute and file the same on behalf of Tenant as Tenant’s agent for such purpose, at
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 mylar as-built drawings are true and correct, which certification shall survive the expiration or termination of this
Lease, and (C) to deliver to Landlord two (2) sets of copies of such record set of drawings within ninety (90) days following issuance of a certificate of occupancy for the Premises, and (ii) Tenant shall deliver to Landlord a
copy of all warranties, guaranties, and operating manuals and information relating to the improvements, equipment, and systems in the Premises constructed by Tenant.

 5.2 Landlord’s
Representative. Landlord has designated Bart Kraft (bkraff@mcmllc.com/ (802 362-4410) as its sole representative with respect to the matters set forth in this Work Letter, who, until further notice to Tenant, shall have full authority and
responsibility to act on behalf of the Landlord as required in this Work Letter. 
 5.3 Time of the Essence in This Work Letter.
Unless otherwise indicated, all references herein to a “number of days” shall mean and refer to calendar days. If any item requiring approval is timely disapproved by Landlord, the procedure for preparation of the document and approval
thereof shall be repeated until the document is approved by Landlord 
 5.4 Tenant’s Lease Default. Notwithstanding any
provision to the contrary contained in the Lease, if a Default as described in the Lease or this Work Letter has occurred at any time on or before the substantial completion of the Tenant Improvements and Compliance Work then (i) in addition to
all other rights and remedies granted to Landlord pursuant to this Lease, Landlord shall have the right to withhold payment of all or any portion of the Tenant Improvement Allowance and/or funds which are part of the Compliance Cost Budget and/or
Landlord may cause Contractor to cease the construction of the Premises (in which case, Tenant shall be responsible for any delay in the substantial completion of the Premises caused by such work stoppage), and (ii) all other obligations of
Landlord under the terms of this Work Letter shall be forgiven until such time as such default is cured pursuant to the terms of the Lease (in which case, Tenant shall be responsible for any delay in the substantial completion of the Premises caused
by such inaction by Landlord). 
 5.5 Tenant’s Agents. All subcontractors, laborers, materialmen, and suppliers retained
directly by Tenant shall conduct their activities in and around the Premises, Building and the Site in a harmonious relationship with all other subcontractors, laborers, materialmen and suppliers at the Premises, Building and Site. 

5.6 Hazardous Materials. If the construction of the Tenant Improvements or Compliance Work or Tenant’s move into the Premises will
involve the use of or disturb Hazardous Materials existing in the Premises, Tenant shall comply with Landlord’s rules and regulations concerning such Hazardous Materials. In the event any Hazardous Materials (as defined in the Lease) are
discovered or are present at the Premises as of the date of this Lease, none of the Tenant Improvement Allowance shall be used or applied to remediate or remove any 

  
 A-15 

 
of such Hazardous Materials, any remediation and/or removal shall be the sole obligation, responsibility and liability of Landlord and none of the cost thereof shall be part of Common Operating
Expenses. Any delay in completion of the Tenant Improvements resulting from the discovery, remediation and/or removal of Hazardous Materials shall be a Landlord Delay. 

5.7 Landlord Delay. As used herein, (x) “Force Majeure Construction Delay” shall mean acts of God, casualties,
natural disasters, strikes, war, terrorist attacks, lockouts, labor disputes or civil commotion, and (y) “Landlord Delay” shall mean a delay in the construction of the Tenant Improvements or Compliance Work resulting directly
from the acts or omissions of Landlord, Landlord’s employees, agents, or contractors including, but not limited to (i) failure of Landlord to timely approve or disapprove any plans; (ii) interference by Landlord, its employees, agents
or contractors with the completion of the Tenant Improvements or Compliance Work (including the impairment of Tenant’s contractors’ or vendors’ or employees’ access to the Premises for any reason (including due to the presence of
Landlord’s contractors, vendors or personnel), failure to provide reasonable access to the Building’s loading docks or other facilities necessary for the construction of the Tenant Improvements or Compliance Work and/or the movement of
materials and personnel to the Premises for such purpose) and (iii) delays due to the acts or failures to act of Landlord, its agents or contractors with respect to payment of the Tenant Improvement Allowance. If Tenant contends that a Force
Majeure Construction Delay or a Landlord Delay has occurred, Tenant acknowledges and agrees that it has inspected the Building and the Site and in no event shall the physical character or condition of the Building and/or Site existing as of the
Effective Date constitute a basis for a Landlord Delay (this agreement does not apply to the failure of any Building component to properly operate). Further, in no event shall any delay of Landlord constitute a Landlord Delay unless such delay
results in a full day of delay in the construction of the Tenant Improvements or Compliance Work. Tenant shall notify Landlord in writing (the “Delay Notice”) of the event which constitutes such Force Majeure Construction Delay or
Landlord Delay; such notice may be via electronic mail to Landlord’s construction representative described above. Tenant will additionally use reasonable efforts to mitigate the effects of any Force Majeure Construction Delay or Landlord Delay
through the re-sequencing or re-scheduling of work, if feasible, but this sentence will not be deemed to require Tenant to incur overtime or after-hours costs unless Landlord agrees in writing to bear such costs. If the actions or inactions or
circumstances described in the Delay Notice constitute a Landlord Delay, and are not cured by Landlord within one (1) business day after Landlord’s receipt of the Delay Notice, then a Landlord Delay shall be deemed to have occurred
commencing as of the expiration of such one (l)-business day period. The Lease Commencement Date and the Lease Expiration Date will each be delayed on a day for day basis for each day of Force Majeure Construction Delay or Landlord Delay. 

5.8 If and to the extent that Landlord fails to fund any monthly disbursement of the Tenant Improvement Allowance within thirty (30) days
following Tenant’s submission to Landlord of a draw request containing all of the materials and information required pursuant to Sections 2.2.2 or 2.3, Tenant shall be entitled to fund the amount set forth in Tenant’s draw request,
provided that Tenant will concurrently deliver notice to Landlord of the amount so funded by Tenant. Additionally, if and to the extent that Landlord’s failure to timely fund a monthly disbursement of the Tenant Improvement Allowance causes

 FIRST AMENDMENT TO LEASE 

THIS FIRST AMENDMENT TO LEASE (the “First Amendment”) is made and entered into as of April 28, 2015 by and between Six
Thirty-Four Second Street, LLC, a Delaware limited liability company (“Landlord”) and OKTA Inc., a Delaware corporation (“Tenant”). 

RECITALS 

This First Amendment is made with respect to the following facts and circumstances: 

 

	 	A.	Landlord and Tenant entered into that certain Agreement of Lease dated December 11, 2014 (the “Lease”) whereby Tenant is leasing from Landlord and Landlord is leasing to Tenant certain premises
located at 634 Second Street, San Francisco, California. 

  

	 	B.	The Lease provides, in part, at Section 7 of the Lease for a security deposit in the amount of Two Million Seven Hundred Seventy-Three Thousand Two Hundred Eighty-Seven Dollars ($2,773,287) (the “Security
Deposit”) and further provides that the amount of the Security Deposit may be delivered by Tenant in the form of cash or a letter of credit (“LOC”). It is acknowledged that Tenant has delivered to Landlord a LOC in the full
amount of the Security Deposit. 

  

	 	C.	Landlord and Tenant desire to modify the Lease to provide for a reduction in the amount of the Security Deposit subject to the occurrence of certain conditions in accordance with the provisions of this First Amendment.

 NOW, THEREFORE, for good and valuable consideration the receipt and sufficiency of which are hereby acknowledged, Landlord
and Tenant agree as follows: 
 1. Recitals. The above Recitals are incorporated herein by this reference. 

2. Reduced Security Deposit. The initial amount of the Security Deposit in the amount of Two Million Seven Hundred Seventy-Three
Thousand Two Hundred Eighty-Seven Dollars ($2,773,287) whether deposited in cash or by delivery of a LOC shall, subject to the provisions of this First Amendment be reduced in accordance with the following: 

(a) At the expiration of the fourth “Lease Year,” as that term is defined below, the amount of the Security Deposit shall be
reduced to a sum equal to One Million One Hundred Forty-Eight Thousand One Hundred Seventy-Nine Dollars ($1,148,179); and 
 (b) At the
expiration of the sixth Lease Year the amount of the Security Deposit shall be reduced to Nine Hundred Seventy-Four Thousand Four Hundred Eighty Three Dollars ($974,483). 

For purposes hereof the term “Lease Year” shall refer to each twelve (12) month period of the Term commencing as of the
Lease Commencement Date with respect to the first Lease Year and the anniversary of the Lease Commencement Date with respect to each Lease Year thereafter. 

  
 D-5 

 3. Reduction Conditions. Each reduction in the amount of the Security Deposit as provided
in Section 2 above shall be conditioned upon no monetary Default of Tenant (i.e., a default described in any of Sections 25.1(b), 25.1(c) or 25.1(e) of the Lease) having occurred during the Lease Year at the expiration of which the
Security Deposit reduction pursuant to the provisions of Section 2 above is scheduled to occur. The reduction in the amount of Security Deposit as provided in Section 2(b), if Tenant qualifies for such reduction, may occur notwithstanding
that Tenant may have failed to qualify for the reduction as provided in Section 2(a) above by reason of a monetary Default of Tenant. 

4. Alternative Conditions to Reduction. Notwithstanding whether or not the reductions in the amount of the Security Deposit pursuant to
the provisions of Section 2 have occurred, provided that no monetary Default by Tenant has occurred during the immediately preceding twelve (12) month period, the amount of the Security Deposit shall be reduced to an amount equal to Five
Hundred Thirty-Two Thousand Four Hundred Twenty-Two Dollars ($532,422) upon the occurrence of all of the following: 
 (a) During the
immediately preceding four (4) calendar quarters Tenant has achieved net profit during each such quarter totaling for all such quarters at least Twenty Million Dollars ($20,000,000) and EBITDA in the minimum amount of Seven Million Dollars
($7,000,000) for each of such quarters; and 
 (b) The then balance sheet pursuant to the financial statements prepared for Tenant shows a
minimum of One Hundred Million Dollars ($100,000,000) of cash or cash equivalents. 
 Satisfaction of the above requirements shall be
reflected, if at all, in the then current financial statement for Tenant prepared by the independent certified public accountants then being employed by Tenant. In the event that the conditions for the reduction in the amount of Security Deposit as
provided in Sections 4(a) and 4(b) have occurred, and the Tenant does not qualify for the Security Deposit reduction by reason of a monetary Default occurring in the immediately prior twelve (12) month period then thereafter Tenant shall
continue to be entitled to the reduction in the amount of Security Deposit as provided in this Section 4 at such time as the conditions as provided in Section 4(a) and 4(b) have been satisfied and no monetary Default by Tenant has occurred
in the immediately preceding twelve (12) month period. 
 5. Additional Alternative Conditions. Notwithstanding whether or not
any of the reductions as provided in Sections 2 and 4 above have occurred, provided no monetary Default by Tenant has occurred in the immediately preceding twelve (12) month period, in the event that a Qualified Public Offering occurs and
(i) Tenant has achieved net income (excluding gains from sales of assets and any extraordinary items) cumulatively of at least Twenty Million Dollars ($20,000,000) for any four (4) consecutive quarters and (ii) Tenant has achieved an
average total equity capitalization (at market value) of at least One Billion Dollars ($1,000,000,000) on a fully diluted basis based on its closing share price over any ten (10) consecutive trading days the amount of the Security Deposit shall
be reduced to Five Hundred Thirty-Two Thousand Four Hundred Twenty-Two Dollars ($532,422). For purposes hereof the term “Qualified Public Offering” means the sale, and a firm commitment underwritten public offering, led by a
nationally recognized underwriting firm, pursuant to an effective registration statement under the 

  
 D-6 

 
Securities Act of 1933 as amended, or any successor, federal statute, rules and regulations thereunder of common stock of tenant having an aggregate offering value (net of underwriter’s
discounts and selling commissions) of at least Four Hundred Million Dollars, following which at least fifty percent (50%) of the total stock of Tenant on a fully diluted basis, will have been sold to the public and will be listed on a national
securities exchange or quoted on the NASDAQ Stock Market System. For purposes hereof the term “fully diluted basis” means as of any date of determination, with respect to all stock of Tenant, all issued and outstanding stock, and all stock
issuable upon the exercise of any outstanding option, warrant or other right to subscribe for, purchase, or acquire stock of Tenant as of such date whether or not at the time any such options, warrants or other rights are exercisable. 

6. Limitation on Reductions. The reductions in the amount of the Security Deposit as provided in Section 2, 4 and 5 are not
intended to be cumulative and although Tenant may qualify for a reduction pursuant to more than one of such paragraphs, the amount of the reduction shall be limited as provided in the paragraph allowing for the greatest amount of reduction. In no
event shall the amount of the Security Deposit be reduced to an amount less than Five Hundred Thirty-Two Thousand Four Hundred Twenty-Two Dollars ($532,422). 

7. No Subsequent Increases. In the event of any reduction in the amount of the Security Deposit in accordance with one or more of the
provisions of Sections 2, 4 or 5 above in no event thereafter shall the amount of the Security Deposit thereafter be increased. 

8. Ratification; Definitions. Except as expressly amended hereby, all terms and provisions of the Lease shall remain in full force and
effect and are hereby ratified and reaffirmed. Except as expressly defined herein, the defined terms employed in this First Amendment shall have the same meaning as ascribed to such terms in the Lease. 

9. Counterparts. This First Amendment may be executed by the parties hereto in two or more counterparts, each of which executed
counterparts shall be considered an original and together shall constitute one and the same document. It shall not be necessary that each party execute each counterpart, or that any one counterpart be executed by more than one party, so long as each
party executes at least one counterpart. 
 10. Electronic Execution. This First Amendment may be executed by facsimile, PDF or by
other electronic means of communication. 
 11. Entire Agreement. This First Amendment sets 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 other than the Lease as hereby amended by the First Amendment. 

12. Inurement. This First Amendment shall be binding upon and shall inure to the benefit of the parties and their respective
beneficiaries, legal representatives, heirs, successors and assigns. 
 13. Conflicts. In the event of a conflict between the terms
and provisions of this First Amendment and the terms and provisions of the Lease, the terms and provisions of this First Amendment shall control.

 THIRD AMENDMENT TO LEASE 

THIS THIRD AMENDMENT TO LEASE (the “Third Amendment”) is made and entered into as of June 24, 2016 by and between Six
Thirty Four Second Street, LLC, a Delaware limited liability company (“Landlord”) and Okta, Inc., a Delaware corporation (“Tenant”). 

RECITALS 

This Third Amendment is made with respect to the following facts and circumstances: 

 

	 	A.	Landlord and Tenant entered into that certain Agreement of Lease dated December 11, 2014 (the “Initial Lease”) as thereafter amended by that certain First Amendment to Lease dated April 28,
2015 and as thereafter amended by that certain Second Amendment to Lease dated January 14, 2016 by and between Landlord and Tenant (collectively with the Initial Lease, the “Lease”) whereby Tenant is leasing from Landlord and
Landlord is leasing to Tenant certain premises located at 634 Second Street, San Francisco, California (the “Building”) (the “Premises”). 

 

	 	B.	Tenant intends to proceed to reopen the sky bridge between the Building and the building located at 301 Brannan Street, San Francisco, California (the “Sky Bridge” and such building, “Brannan
Street”) as contemplated pursuant to the provisions of Section 49 of the Initial Lease. Landlord and Tenant desire to clarify and further define the obligations of Tenant with respect to the reopening of the Sky Bridge.

 NOW, THEREFORE, for good and valuable consideration the receipt and sufficiency of which are hereby acknowledged, Landlord
and Tenant agree as follows: 
 1. Recitals. The above Recitals are incorporated herein by this reference. 

2. Sky Bridge Modifications. Landlord and Tenant hereby agree that the alterations to the Premises required or otherwise to be
performed in connection with the opening of the Sky Bridge shall constitute Changes pursuant to the provisions of Sections 14.1 of the Initial Lease and except as otherwise provided in this Third Amendment, such Changes shall be subject to all
of the provisions of Section 14 of the Initial Lease applicable to Changes. The Changes made in connection with the opening of the Sky Bridge shall sometimes collectively be referred to as the “Sky Bridge Changes”. 

3. Limitations. In no event shall the Sky Bridge Changes to be made or proposed to be made in connection with opening the Sky Bridge
impair or weaken the structural strength or integrity of the Building or result, without the consent of Landlord in its discretion, in an increase in premiums for insurance carried by Landlord with respect to the Building. In the event of any such
increase as approved by Landlord in its discretion, Tenant shall be responsible for the entire cost of any such increased premiums, which cost shall be paid by Tenant as additional rent pursuant to the Lease within thirty (30) days following
delivery by Landlord to Tenant of a written invoice for the additional cost. 
 4. Restoration. Upon surrender of the Premises or
earlier termination of the Lease Tenant shall be obligated to remove the Sky Bridge Changes and to restore the Premises to its 

  
 D-11 

 
condition prior to making the Sky Bridge changes, reasonable wear and tear excepted, all of which removal and restoration shall be made at the sole cost of Tenant. If Tenant fails to complete the
removal and restoration prior to expiration of the Term or earlier termination of this Lease, Landlord may complete such removal and restoration and charge the cost of such removal and restoration to Tenant. Notwithstanding the above provision of
this Section 4 to the contrary. Tenant may at any time, no earlier than ninety (90) days prior to the expiration of the Term, give written notice to Landlord (“Removal Notice”) requesting that Landlord agree that Tenant
need not remove the Sky Bridge Changes and restore the Premises upon expiration of the Term of the Lease and surrender of the Premises by Tenant. The agreement of Landlord to any request made by Tenant pursuant to Removal Notice may be withheld or
given in Landlord’s sole and absolute discretion, but in any event Landlord will respond within thirty (30) days, and any delay beyond such thirty (30) day period on the part of Landlord in responding will delay the outside date for
Tenant’s completion of such work on a day-for-day basis. In connection with Landlord’s response to any Removal Notice, Landlord may require that components of the Sky Bridge Changes be removed with related restoration and that other
components of the Sky Bridge Changes remain. Unless Landlord in a written response to Tenant to any Removal Notice has agreed in writing that the Sky Bridge Changes (or any component thereof) need not be removed by Tenant, Tenant shall be obligated,
at its sole cost, to remove the Sky Bridge Changes and restore the Premises prior to expiration of the Term. If and to the extent that Landlord responds to a Renewal Notice that all or any portion of the Sky Bridge will not be required to be
removed, Tenant will be forever released from any requirement to remove the Sky Bridge Changes which Landlord has specifically agreed in writing need not be removed and Tenant shall continue to be obligated to remove all other Sky Bridge Changes and
to restore the Premises. 
 5. Costs. Consistent with the provisions relating to Changes pursuant to Section 14 of the Lease,
Tenant shall be responsible for any and all costs of any kind whatsoever arising out of or relating to the Sky Bridge Changes including, without limitation, all costs of construction, all fees and costs relating to governmental approvals, the cost
of all consultants, including, without limitation, the reasonable cost of third party consultants and attorneys reasonably engaged by Landlord in connection with the Sky Bridge Changes, and all other costs relating to or arising from the Sky Bridge
Changes. In connection therewith, if and to the extent that Landlord intends to retain a third party consultant to review any Sky Bridge Changes and/or incur any other material costs relating to or arising from the Sky Bridge Changes, Landlord will
notify Tenant in advance, and, to the extent reasonably possible, keep Tenant apprised of the anticipated cost of same. 
 6. Further
Limitations. It is acknowledged and agreed that although the entry to the Sky Bridge from the Building constitutes a portion of the Premises and Building, the Sky Bridge between the Building and Brannan Street does not constitute a portion of
the Premises or the Building and Landlord has no responsibility whatsoever for the Sky Bridge including, without limitation, any responsibility for or obligation with respect to (i) the structural integrity of the Sky Bridge, (ii) any
costs relating to the Sky Bridge including, without limitation, any maintenance or repair costs, (iii) compliance with applicable law, (iv) the provision of any insurance coverage, (v) the habitability, suitability or feasibility for
the use intended by Tenant, (vi) any utilities or services with respect to the Sky Bridge, and (vii) any and all other matters arising out of or relating to the Sky Bridge. Without limiting the generality of the above, and notwithstanding
that the Sky Bridge does not constitute a portion of the Building or Premises, the 

  
 D-12 

 
provisions of Section 19.1 of the Initial Lease shall be applicable with respect to the Sky Bridge and the indemnity obligations of Tenant as provided in Section 19.1 shall apply with
respect to matters relating to the Sky Bridge. Further, Tenant shall be solely responsible for obtaining any and all required consents of the owner of Brannan Street to the opening of the Sky Bridge, and the other matters as contemplated by this
Third Amendment and Landlord shall have no responsibility for obtaining any such consents as may be required. Notwithstanding any provision of this Third Amendment to the contrary, Tenant shall not be entitled to proceed with the Sky Bridge Changes
until and unless any and all consents of the owner of Brannan Street to the opening of the Sky Bridge as contemplated by this Third Amendment have been obtained, and evidence of such consents in a form reasonably acceptable to Landlord has been
delivered to Landlord. In no event shall any consent from the owner of Brannan Street be inconsistent with the provisions of this Third Amendment including, without limitation, the limitation on the obligations of Landlord as provided herein with
respect to the Sky Bridge or purport to impose any obligations on Landlord. 
 7. Ratification: Definitions. Except as expressly
amended hereby, all terms and provisions of the Lease shall remain in full force and effect and are hereby ratified and reaffirmed. Except as express Ly defined herein, the defined terms employed in this Third Amendment shall have the same meaning
as ascribed to such terms in the Lease. 
 8. Counterparts. This Third Amendment may be executed by the parties hereto in two or more
counterparts, each of which executed counterparts shall be considered an original and together shall constitute one and the same document. It shall not be necessary that each party execute each counterpart, or that any one counterpart be executed by
more than one party, so long as each party executes at least one counterpart. 
 9. Electronic Execution. This Third Amendment may be
executed by facsimile, PDF or by other electronic means of communication. 
 10. Entire Agreement. This Third Amendment sets 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 other titan the Lease as hereby amended by the Third Amendment. 

11. Inurement. This Third Amendment shall be binding upon and shall inure to the benefit of the parties and their respective
beneficiaries, legal representatives, heirs, successors and assigns. 
 12. Conflicts. In the event of a conflict between the terms
and provisions of this Third Amendment and the terms and provisions of the Lease, the terms and provisions of this Third Amendment shall control. 

13. Controlling Law. This Third Amendment will be governed by the laws of the State of California.
