 Exhibit 10.9 

Double Trigger Acceleration Policy 

Summary: ‘‘Double trigger” acceleration of 100% of the unvested options held by any optionee then employed by the Company (or then providing
services to the Company as a consultant if such acceleration is specifically approved by the Board for such consultant) would occur if the optionee is terminated without “Good Cause” (as defined below) or resigns for
“Good Reason” (as defined below) within 3 months before or 12 months following the consummation of a Change of Control (a definition that includes acquisitions in various forms but excludes financings for capital-raising purposes).
Explanations in bold and brackets below. 
 “Good Cause” shall mean, as reasonably determined by the Board (excluding any
Participant who is then a member of the Board) based on the information then known to it, that one or more of the following has occurred: 

(i) the Participant is convicted of, or pleads guilty or nolo contendere to, a felony (under the laws of the United States or any
relevant state, or a. similar crime or offense under the applicable laws of any relevant foreign jurisdiction); 
 (ii) the Participant has
engaged in acts of fraud, dishonesty or other acts of willful misconduct in the course of his duties hereunder; 
 (iii) the Participant
willfully fails to perform or uphold his or her duties under this Agreement after receiving written notice from the Board or willfully fails to comply with reasonable directives of the Board without a reasonable belief the failure to comply was in
the best interest of the Company; or 
 (iv) a material breach by the Participant of any other provision of this Agreement, or any material
breach by the Participant of any other contract the Participant is party to with the Company or any of its Affiliates; provided, however, that if the breach is reasonably susceptible of cure, Participant shall be entitled to receive at least 30 days
to cure the breach fully after receiving written notice from the Board. 
 “Good Reason” shall mean the occurrence of any
of the following conditions without the Participant’s express written consent: 
 (i) a 15% or greater reduction in the
Participant’s rate of base salary unless such reduction is consistent with a salary reduction implemented by the Company for other similarly situated employees of the Company; 

(ii) a material diminution in the Participant’s authority, title, duties, or responsibilities; provided, however, that such diminution
will not be “Good Reason” if the Participant’s authority or title has, or duties or responsibilities have, been diminished due to an increase in the size, or the number of employees of, the Company and its affiliated entities taken
together as a whole (for the avoidance of doubt and for purposes of illustration, if immediately prior to a Change of Control the Participant supervises 10 

 
of 20 employees of the Company and its affiliated entities, the Participant would not have “Good Reason” if he or she resigned after the Change of Control solely because he or she
continued to supervise 10 employees but the total number of employees of the Company and its affiliated entities increased to 500 employees); 

(iii) a relocation of the Participant’s principal office with the Company of more than fifty (50) miles from its current location; or

 (iv) a material breach by the Company of this Agreement; 

provided, however, that any such condition or conditions, as applicable, shall not constitute Good Reason unless both (x) the Participant provides
written notice to the Company of the condition claimed to constitute Good Reason within ninety (90) days of the initial existence of such condition(s) (such notice to be delivered in accordance with Section [    ]), and
(y) the Company fails to remedy such condition(s) within thirty (30) days of receiving such written notice thereof; and provided, further, that in all events the termination of the Participant’s employment with the Company shall not
be treated as a termination for “Good Reason” unless such termination occurs not more than one hundred and twenty (120) days following the initial existence of the condition claimed to constitute Good Reason.EX-10.10

Sublease including the obligation to pay rent. For so long as the Security Deposit has not been repaid to Subtenant, it shall constitute an account payable by Sublandlord to Subtenant within
thirty (30) days after the termination of this Sublease to the extent, if any, that the Security Deposit has not been applied by Sublandlord as hereinafter provided. If Subtenant shall default beyond any applicable notice and cure periods as
defined herein with respect to any term and condition hereunder, then the Security Deposit or any part hereof may be applied by Sublandlord (but Sublandlord shall not be obligated to do so) to the actual damages sustained by Sublandlord by reason
thereof. No such application shall be construed as an agreement to limit the amount of Sublandlord’s claim or, as a waiver of any damage or release of any indebtedness, and Sublandlord’s claim not recovered in full from the Security
Deposit. If Sublandlord has so applied all or any part of the Security Deposit, Sublandlord shall have the right (but not the obligation) at any time thereafter to demand that Subtenant pay to Sublandlord a sum equal to the amounts so applied so
that Sublandlord will always be in possession of a sum equal to the amount of the Security Deposit. Subtenant shall make each such remittance within thirty (30) days following such demand by Sublandlord. Said remittance shall thereupon
constitute a part of the Security Deposit subject to the terms and provisions hereof. The failure of Subtenant to make any such requested remittance within such thirty (30) day period, and after applicable notice and cure period, may be treated
by Sublandlord as a failure by Subtenant to make timely payment of rent and as an event of default.

provided in Section 9 hereof, the covenants, agreements, terms, provisions and conditions of the Master Lease insofar as they relate to the Subleased Premises and insofar as they are not inconsistent with the terms of this Sublease are made a
part of and incorporated into this Sublease as if recited herein in full, and the rights and obligations of the Landlord and the Tenant under the Master Lease shall be deemed the rights and obligations of Sublandlord and Subtenant respectively
hereunder and shall be binding upon and inure to the benefit of Sublandlord and Subtenant respectively. The time limits contained in the Master Lease for the giving of notices, making of demands or performing of any act, condition or covenant on the
part of the tenant thereunder, or for the exercise by the tenant thereunder of any right, remedy or option, be changed for the purposes of incorporation herein by reference by shortening the same in each instance by three (3) business days, so

the last line of Section 19.1.1, under which Subtenant shall have only one (1) business day less time. As between the parties hereto only, in the event of a conflict between the terms of the Master Lease and the terms of this Sublease,

“Sublease”), with respect to a subletting by Subtenant of a portion of the Premises on the third (3rd) floor of the Building containing 32,571 rentable square feet, as more particularly described in the Sublease (the
“Sublet Premises”). A copy of the Sublease is attached hereto as Exhibit “A”. Landlord is willing to consent to the Sublease on the terms and conditions contained herein. 

C. All defined terms not otherwise expressly defined herein shall have the respective meanings given in the Lease. 

A G R E E M E N T : 
 1.
Landlord’s Consent. Landlord hereby consents to the Sublease; provided, however, notwithstanding anything contained in the Sublease to the contrary, such consent is granted by Landlord only upon the terms and conditions set forth in this
Agreement. The Sublease is subject and subordinate to the Lease. Neither this Agreement nor the Sublease shall be construed to modify, waive or amend any of the terms, covenants and conditions of the Lease or to waive any breach thereof or any of
Landlord’s rights or remedies thereunder or to enlarge or increase any obligations of Landlord under the Lease. Landlord shall not be bound by any of the terms, covenants, conditions, provisions or agreements of the Sublease. 

2. Non-Release of Tenant; Further Transfers. Neither the Sublease nor this consent thereto shall release or discharge Tenant from any
liability, whether past, present or future, under the Lease or alter the primary liability of the Tenant to pay the rent and perform and comply with all of the obligations of Tenant to be performed under the Lease (including the payment of all bills
rendered by Landlord for charges incurred by the Subtenant for services and materials supplied to the Sublet Premises). Neither the Sublease nor this consent thereto shall be construed as a waiver of Landlord’s right to consent to any further
subletting either by Tenant or by the Subtenant or to any assignment by Tenant of the Lease or assignment by the Subtenant of the Sublease, or as a consent to any portion of the Sublet Premises being used or occupied by any other party. Landlord may
consent to subsequent sublettings and assignments of the Lease or the Sublease or any amendments or modifications thereto without notifying Tenant or anyone else 

  
 1 

 
liable under the Lease and without obtaining their consent. No such action by Landlord shall relieve such persons from any liability to Landlord or otherwise with regard to the Sublet Premises.

 3. Relationship with Landlord. Tenant hereby assigns and transfers to Landlord the Tenant’s interest in the Sublease and all
rentals and income arising therefrom, subject to the terms of this Section 3. Landlord, by consenting to the Sublease agrees that until a default shall occur in the performance of Tenant’s obligations under the Lease, Tenant may receive,
collect and enjoy the rents accruing under the Sublease. In the event Tenant shall default in the performance of its obligations to Landlord under the Lease (whether or not Landlord terminates the Lease), Landlord may, at its option, by giving
notice to Tenant, either (i) terminate the Sublease, (ii) elect to receive and collect, directly from Subtenant, all rent any other sums owing and to be owed under the Sublease, as further set forth in Section 3.1, below, and/or
(iii) elect to succeed to Tenant’s interest in the Sublease, and cause Subtenant to attorn to Landlord, as further set forth in Section 3.2, below. 

3.1 Landlord’s Election to Receive Rents. Landlord shall not, by reason of the Sublease, nor by reason of the collection of rents
or any other sums from the Subtenant pursuant to Section 3(ii), above, be deemed liable to Subtenant for any failure of Tenant to perform and comply with any obligation of Tenant, and Tenant hereby irrevocably authorizes and directs Subtenant,
upon receipt of any written notice from Landlord stating that a default exists in the performance of Tenant’s obligations under the Lease, to pay to Landlord the rents and any other sums due and to become due under the Sublease. Tenant agrees
that Subtenant shall have the right to rely upon any such statement and request from Landlord, and that Subtenant shall pay any such rents and any other sums to Landlord without any obligation or right to inquire as to whether such default exists
and notwithstanding any notice from or claim from Tenant to the contrary. Tenant shall not have any right or claim against Subtenant for any such rents or any other sums so paid by Subtenant to Landlord. Landlord shall credit tenant with any rent
received by Landlord under such assignment but the acceptance of any payment on account of rent from the Subtenant as the result of any such default shall in no manner whatsoever be deemed an attornment by the Landlord to Subtenant or by Subtenant
to Landlord, be deemed a waiver by Landlord of any provision of the Lease or serve to release Tenant from any liability under the terms, covenants, conditions, provisions or agreements under the Lease. Notwithstanding the foregoing, any payment of
rent from the Subtenant directly to Landlord, regardless of the circumstances or reasons therefor, shall in no manner whatsoever be deemed an attornment by the Subtenant to Landlord in the absence of a specific written agreement signed by Landlord
to such an effect. 
 3.2 Landlord’s Election of Tenant’s Attornment. In the event Landlord elects, at its option, to cause
Subtenant to attorn to Landlord pursuant to Section 3(iii), above, Landlord shall undertake the obligations of Tenant under the Sublease from the time of the exercise of the option, but Landlord shall not (i) be liable for any prepayment
of more than one (1) month’s rent or any security deposit paid by Subtenant to Tenant, (ii) be liable for any previous act or omission of Tenant under the Sublease or for any other defaults of Tenant under the Sublease, (iii) be
subject to any defenses or offsets previously accrued which Subtenant may have against Tenant, or (iv) be bound by any changes or modifications made to the Sublease without the written consent of Landlord. 

4. General Provisions. 

4.1 Consideration for Sublease. Tenant and Subtenant represent and warrant that there are no additional payments of rent or any other
consideration of any type payable by Subtenant to Tenant with regard to the Sublet Premises other than as disclosed in the Sublease. 
 4.2
Brokerage Commission. Tenant and Subtenant covenant and agree that under no circumstances shall Landlord be liable for any brokerage commission or other charge or expense in connection with the Sublease and Tenant and Subtenant agree to
protect, defend, indemnify and hold Landlord harmless from the same and from any cost or expense (including, but not limited to, attorney’s fees) incurred by Landlord in resisting any claim for any such brokerage commission. 

4.3 Controlling Law. The terms and provisions of this Agreement shall be construed in accordance with and governed by the laws of the
State of California.

unenforceable, shall not be affected thereby, and each and every other term, provision and condition of this Agreement shall be valid and enforceable to the fullest extent possible permitted by law.

it is not acting, directly or indirectly, for or on behalf of any person, group, entity, or nation named by any Executive Order of the United States Treasury Department as a terrorist, “Specially Designated National and Blocked Person,” or
other banned or blocked person, entity, nation, or transaction pursuant to any law, order, rule, or regulation that is enforced or administered by the Office of Foreign Assets Control; and it is not engaged in this transaction, directly or
indirectly on behalf of, or instigating or facilitating this transaction, directly or indirectly on behalf of, any such person, group, entity, or nation. Subtenant hereby agrees to defend, indemnify, and hold harmless Landlord from and against any
and all claims, damages, losses, risks, liabilities, and expenses (including attorney’s fees and costs) arising from or related to any breach of the foregoing certification.

In the event that the term of this Sublease shall begin or end on a date which is not the first day of a month, base rent shall be prorated as of such date.

 If Subtenant is in default of the payment of Rent or Additional Rent or any other provision of this Sublease beyond any applicable notice or cure period,
in addition to any Default Remedies available to Sublandlord, Subtenant shall be obligated to repay the three (3) month rental abatement received at the commencement of the Sublease Term. 

Concurrent with Subtenant’s execution of this Sublease, Subtenant shall deliver to Sublandlord the first month’s base rent in the
amount of Eighty One Thousand, Four Hundred Twenty Seven and 50/100 Dollars ($81,427.50). 

7. Security Deposit Concurrent with the execution of this Sublease, Subtenant shall deposit with Sublandlord a sum equal to One
Hundred Sixty Two Thousand, Eight Hundred Fifty Five and 00/100 Dollars ($162,855.00) (hereinafter referred to as the “Security
Deposit”) as security for the Subtenant’s faithful performance of all of the terms and conditions of this 

  
 2 

 
Sublease including the obligation to pay rent. For so long as the Security Deposit has not been repaid to Subtenant, it shall constitute an account payable by Sublandlord to Subtenant within
thirty (30) days after the termination of this Sublease to the extent, if any, that the Security Deposit has not been applied by Sublandlord as hereinafter provided. If Subtenant shall default beyond any applicable notice and cure periods as
defined herein with respect to any term and condition hereunder, then the Security Deposit or any part hereof may be applied by Sublandlord (but Sublandlord shall not be obligated to do so) to the actual damages sustained by Sublandlord by reason
thereof. No such application shall be construed as an agreement to limit the amount of Sublandlord’s claim or, as a waiver of any damage or release of any indebtedness, and Sublandlord’s claim not recovered in full from the Security
Deposit. If Sublandlord has so applied all or any part of the Security Deposit, Sublandlord shall have the right (but not the obligation) at any time thereafter to demand that Subtenant pay to Sublandlord a sum equal to the amounts so applied so
that Sublandlord will always be in possession of a sum equal to the amount of the Security Deposit. Subtenant shall make each such remittance within thirty (30) days following such demand by Sublandlord. Said remittance shall thereupon
constitute a part of the Security Deposit subject to the terms and provisions hereof. The failure of Subtenant to make any such requested remittance within such thirty (30) day period, and after applicable notice and cure period, may be treated
by Sublandlord as a failure by Subtenant to make timely payment of rent and as an event of default. 
 8. Use Subtenant
covenants and agrees to use the Subleased Premises in accordance with the provisions of the Master Lease and for no other purpose and otherwise in accordance with the terms and conditions of the Master Lease and this Sublease. 

9. Master Lease As applied to this Sublease, the words “Landlord” and “Tenant” as used in the Master Lease
shall be deemed to refer to Sublandlord and Subtenant hereunder, respectively. Subtenant and this Sublease shall be subject in all respects to the terms of, and the rights of the Landlord under, the Master Lease. Except as otherwise expressly
provided in Section 9 hereof, the covenants, agreements, terms, provisions and conditions of the Master Lease insofar as they relate to the Subleased Premises and insofar as they are not inconsistent with the terms of this Sublease are made a
part of and incorporated into this Sublease as if recited herein in full, and the rights and obligations of the Landlord and the Tenant under the Master Lease shall be deemed the rights and obligations of Sublandlord and Subtenant respectively
hereunder and shall be binding upon and inure to the benefit of Sublandlord and Subtenant respectively. The time limits contained in the Master Lease for the giving of notices, making of demands or performing of any act, condition or covenant on the
part of the tenant thereunder, or for the exercise by the tenant thereunder of any right, remedy or option, be changed for the purposes of incorporation herein by reference by shortening the same in each instance by three (3) business days, so
that in each instance Subtenant shall have three (3) business days less time to observe or perform hereunder than Sublandlord has as the tenant under the Master Lease; provided that the foregoing shall not apply to the time period set forth in
the last line of Section 19.1.1, under which Subtenant shall have only one (1) business day less time. As between the parties hereto only, in the event of a conflict between the terms of the Master Lease and the terms of this Sublease,
such conflict shall be resolved in every instance in favor of the provisions of this Sublease. 
 10. Operating Expenses / Real Estate
Taxes Subtenant shall pay to Sublandlord its proportionate share (22.83%) of Sublandlord’s operating expenses and real estate taxes above the Base Year of 2013 as additional rent on a monthly basis, commencing on the Sublease
Commencement Date. 
 11. Tenant’s Performance Under Master Lease 

11.1 Subtenant recognizes that Sublandlord is not in a position nor obligated to render any of the services or to perform any of the
obligations required of Landlord under the Master Lease with respect to the furnishing of any services or utilities to the Subleased Premises or the maintenance, repair or restoration of the Subleased Premises. Therefore, Subtenant shall rely upon
and look solely to the Landlord for the performance of such obligations under the Master Lease and Sublandlord shall not be liable to Subtenant for any default of the Landlord under the Master Lease except to the extent (and solely to such extent)
such default is a result of Sublandlord’s act or failure to act. Subtenant shall not have any claim against Sublandlord by reason of the Landlord’s failure or refusal to comply with any of the provisions of the Master Lease unless such
failure or refusal is a result of Sublandlord’s act or failure to act. This 

  
 3 

 
Sublease shall remain in full force and effect notwithstanding the Landlord’s failure or refusal to comply with any such provision of the Master Lease and Subtenant shall pay the base rent
and additional rent and all other charges provided for herein without any abatement, deduction or setoff whatsoever. Notwithstanding the foregoing, if Landlord defaults in any of its obligations under the Master Lease, Subtenant shall be entitled to
participate with Sublandlord in any action undertaken by Sublandlord in the enforcement of Sublandlord’s rights against Landlord. If Sublandlord elects not to take action, whether legal action or otherwise, for the enforcement of
Sublandlord’s rights against Landlord, Subtenant shall have the right to take such action in its own name and, for that purpose and only to such extent, all the rights of Sublandlord under the Lease with respect to the Subleased Premises shall
be and are hereby conferred upon and assigned to Subtenant, and Subtenant shall be subrogated to such rights to the extent they apply to the Subleased Premises. Subtenant shall protect, defend, indemnify and hold Sublandlord harmless from all
claims, costs and liabilities, including attorney’ fees and costs, arising out of or in connection with any such action by Subtenant except to the extent (and solely to such extent) such claim, cost or liability results from Sublandlord’s
act or failure to act. Subtenant covenants and warrants that it fully understands and agrees to be subject to and bound by all of the covenants, agreements, terms, provisions and conditions of the Master Lease, except as modified herein.
Furthermore, Subtenant and Sublandlord further covenant not to take any action or do or perform any act or fail to perform any act which would result in the failure or breach of any of the covenants, agreements, terms, provisions or conditions of
the Master Lease on the part of the Lessee thereunder. 
 11.2 Whenever the consent of Landlord shall be required by, or Landlord shall fail
to perform its obligations under the Master Lease, Sublandlord agrees to use its reasonable efforts to obtain, at Subtenant’s sole cost and expense, such consent and/or performance on behalf of Subtenant. Subtenant shall reimburse Sublandlord
all costs associated with Landlord’s review of Subtenant’s plans and specifications for improvements in the Subleased Premises and all costs incurred by Sublandlord in obtaining Landlord’s consent with respect to any amendments to
this Sublease. In addition to the foregoing, any and all fees incurred to obtain Landlord’s consent to this Sublease shall be apportioned between Sublandlord and Subtenant as follows: 

 

	 	•	 	$0.00 - $1,000.00 paid by Sublandlord 

  

	 	•	 	over $1,000.01 paid by Subtenant 

 Notwithstanding the foregoing, any and all fees incurred to
obtain Landlord’s consent to a further assignment or subletting of the Subleased Premises shall be borne solely by Subtenant. 
 11.3
Sublandlord represents and warrants to Subtenant that the Master Lease is in full force and effect and there are no uncured defaults thereunder. 

12. Variations from Master Lease The following covenants, agreements, terms, provisions and conditions of the Master Lease are
hereby modified or not incorporated herein: 
 12.1 Notwithstanding anything to the contrary set forth in the Master Lease regarding base
rent, the base rent payable under this Sublease and the Term of this Sublease shall be as set forth in Section 6, above. 
 12.2 The
parties hereto represent and warrant to each other that neither party dealt with any broker or finder in connection with the consummation of this Sublease other than CBRE – Sublandlord’s Representative and Cornish & Carey

 This
Office Lease, which includes the preceding Summary of Basic Lease Information (the “Summary”) attached hereto and incorporated herein by this reference (the Office Lease and Summary to be known collectively as the
“Lease”), dated as of the date set forth in Section 1 of the Summary, is made by and between RINCON CENTER ASSOCIATES, a California limited partnership (“Landlord”), and NATIONAL UNION FIRE INSURANCE COMPANY OF
PITTSBURGH, P.A., a Pennsylvania corporation (“Tenant”). 
 ARTICLE 1 

REAL PROPERTY BUILDING PROJECT AND INITIAL PREMISES 

1.1 Real Property, Building, Project and Common Areas. 

1.1.1 Real Property, Building and Project. The “Building,” at; that term is defined herein below, the parking structure
beneath the Building (the “On-site Parking Area”), the Land upon which the Building stands and the “Common Areas,” as that term is defined in Section 1.1.2, below, are sometimes collectively referred to herein as the
“Real Property.” The “Building” means the office building located at Two Rincon Center, San Francisco, California consisting of six (6) floors of office and retail space for lease to general office tenants (the “Two
Rincon Office Portion”), including all tenant improvements and fixtures and other improvements and fixtures thereto, retail establishments on the first floor (the “Two Rincon Retail Portion”), United States Postal Service Facility
(“Postal Facility”) located on the ground floor, and all portions of the Building leased or designated for lease to tenants for office use, parking, storage or support facilities. The rentable square footage of the Building is set
forth in Section 6.1 of the Summary. On top of the Building, but not part of the Building for purposes of this Lease, are Seventeen (17) floors containing residential apartment units (the “Apartment Portion”). The
“Project,” as that term is used in this Lease, shall include the Real Property and “One Rincon Center,” as that term is defined below, and the Apartment Portion. “One Rincon Center” is a five-story plus basement
building comprised of retail stores located on the first (1st) floor (“One Rincon Retail Portion”) and offices located on the second (2nd) through fifth (5th) floors (“One Rincon Office Portion”). The
On-site Parking Area also services One Rincon Center. The Project is shown on the Site Plan attached hereto as Exhibit A. 

1.1.2 Common Areas. Tenant is hereby granted the right to the nonexclusive use of the Common Areas. “Common Areas”
means (i) the lobby area on the ground floor, (ii) the areas on individual floors devoted to corridors, balconies, fire vestibules, elevator foyers, lobbies, electric and telephone closets, restrooms, mechanical rooms, janitor closets and
other similar facilities for the benefit of all tenants (or invitees) on the particular floor, (provided that such areas are not Common Areas on full floors of the Building leased by a single tenant, including Tenant, since such areas are included
within the definition of Premises),those areas of the Building devoted to mechanical and service rooms servicing more than one floor or the Building as a whole and any other portion of the Real Property not leased or designated for lease to tenants
from time to time that are provided for use in common by Landlord, Tenant and other tenants of the Real Property, whether or not any such area is open to the general public, including all fixtures, goods, decor, signs, facilities and landscaping
located in or used in connection with those areas of the Real Property, and including without limitation city sidewalks adjacent to the Real Property and pedestrian walkways, parking areas, ramps, stairways, elevators, escalators, restrooms, patios,
plazas, malls, landscaped areas, decorative walls, service corridors, throughways, loading areas, and parcel pick-up stations located in the Real Property. Notwithstanding anything to the contrary set forth in this Lease, any balconies adjacent to a
portion of the Premises, which balcony is solely accessible from the Premises (the “Tenant Balcony”), shall be for the exclusive use of Tenant and shall be included as part of the Premises for all purposes except the square footage
of the Tenant Balconies shall not be included for purposes of determining Base Rent and Tenant’s Share. The manner in which such Common Areas are maintained and operated Shall be at the reasonable discretion of Landlord, and the use thereof by
Tenant and other persons and entities shall be subject to the Rules and Regulations and such other rules, regulations and restrictions that are required by local governmental and quasi-governmental authorities. Landlord reserves the right to make
alterations or additions to or to change the location or configuration of elements of the Real Property and the Common Areas and to terminate Tenant’s right to use any portion of the Common Areas (provided that such

 
Common Areas are not located on a floor containing a portion of the Premises and are not Tenant Balconies), which ceases to be a “Common Area,” as defined hereinabove; provided,
however, that Landlord shall provide Tenant with fifteen (15) business days prior notice of any of the actions set forth in this Section 1.1.2, above, to be taken by Landlord if such action will substantially interfere with Tenant’s
ability to (i) conduct business in the Premises, (ii) gain access to and from the On-site Parking Area and adjacent streets, or (iii) use the On-site Parking Area. Landlord shall, at all times during the “Lease Term,” as
that term is defined in Section 2.1 of this Lease, maintain and operate the Common Areas in a first-class manner. Additionally, Landlord shall not, without the prior consent of Tenant, which consent shall not be unreasonably withheld or
delayed and which consent shall be deemed granted if not denied by notice received by Landlord within ten (10) business days of Tenant’s receipt of notice from Landlord, make material alterations, reduction, addition, relocation or
reconfiguration to the Building exterior or the Common Areas; provided that notwithstanding the foregoing terms, Tenant’s consent shall not be required, prior to the date Landlord performs any material alteration, reduction or change of, or
addition to, (i) the Building exterior or Common Areas which is required by law, (ii) any retail space located on the ground floor of the Building provided that the lobby space of the Building is not materially reduced thereby, and
(iii) the portion of the lobbies located on floors not occupied Or leased by Tenant or its “Affiliates,” as that term is defined in Section 14.6 of this Lease, excluding the lobbies of those floors of the Building not occupied by
Tenant, but including material decorative changes to other Common Areas, except those alterations to the Building exterior or the Common Areas which are required to comply with applicable laws. Additionally, Landlord shall not, without the prior
consent of tenant, which consent shall not be unreasonably withheld or delayed and which consent shall be deemed granted if not denied by notice received by Landlord within ten (10) business days of Tenant’s receipt of notice from
Landlord, make any material alterations to the Building exterior or the Common Areas, excluding the lobbies of those floors of the Building not occupied by Tenant, but including material decorative changes to other Common Areas, except those
alterations to the Building exterior or the Common Areas which are required to comply with applicable laws. Tenant shall have the right of access to the Premises, the Building and the On-site Parking Area 24-hours per day, 7-days per week during the
Lease Term. 
 1.2 Initial Premises. Upon and subject to the terms, covenants and conditions hereinafter set forth in this Lease,
Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the premises set forth in Section 6 of the Summary (the “Premises”), which Premises are located in the Building. The outline of the floor plan of the
initial Premises is set forth in Exhibit A-1 attached hereto. Tenant’s rights to the Premises include the right to use or access, (i) the janitorial closet and the fan, electrical, and telephone rooms on any floor of the
Building containing an entire fill floor or a portion of the Premises, and (ii) any ceilings or space above the ceilings on any floor of the Building containing the Premises, as necessary for providing utility services such as the installation
of computer cable conduits, as approved by Landlord; provided, however, Landlord shall also have the right to access the areas beneath each floor of the Premises and above the ceiling of each floor of the Premises and the use thereof, together with
the right to install, maintain, use, repair and replace pipes, ducts, conduits, wires, and structural elements leading through the Premises and serving other parts of the Building, so long as such items are concealed by walls, flooring or ceilings.
Such reservation shall in no way affect the maintenance obligations imposed herein. 
 1.3 The Downsize Right. During the initial
Lease Term, Tenant shall have the on- going right during each “Lease Year,” as that term is defined in Section 2.1, below, occurring after the fifth Lease Year, to deliver to Landlord a notice (the “Downsize Notice”)
stating the amount of rentable square feet of the then-current Premises that Tenant does not desire to continue to lease (the “Downsize Space”), and the location, or locations, of the Downsize Space; provided that (i) on the
date of the Downsize Notice and during the twelve (12) months following the date of the Downsize Notice, Tenant is not in (a) monetary default of this Lease, or (b) material non-monetary default of this Lease, beyond the expiration of
any applicable cure period provided in this Lease (collectively, a “Material Default”), (ii) the Downsize Space shall not be more than ten percent (10%), in the aggregate, of the then-current rentable square footage of the
Premises, (iii) the Downsize Space shall be in a reasonably leasable configuration, provided that any costs incurred in connection with any reconfiguration shall be Tenant’s responsibility, (iv) be located on a multi-tenant floor, and
(v) be in a configuration which permits access to the corridor in compliance with applicable laws. Subject to the foregoing, if Tenant timely delivers to Landlord the Downsize Notice, then as of the date occurring twelve
(12)

  
 2 

 
months after delivery of the Downsize Notice (the “Downsize Termination Date”), this Lease with respect to the Downsize Space shall automatically terminate and be of no further
force or effect and Landlord and Tenant shall be relieved of their respective obligations under this Lease with respect to the Downsize Space, except for those obligations set forth in this Lease which relate to the Downsize Space and specifically
survive the expiration or earlier termination of this Lease, including without limitation, the payment by either party of all amounts owed to the other party under this Lease with respect to the Downsize Space up to and including the Termination
Date. Tenant shall surrender any Downsize Space in accordance with the terms of Section 15.2, below. 
 1.4 Stipulation of Rentable
Square Feet of Initial Premises and Building; Determination of Rentable Square Feet of Additional Space. For purposes of this Lease, “rentable square feet” shall be calculated pursuant to Standard Method for Measuring Floor Area in
Office Buildings, ANSI Z65.1 – 1980 (“BOMA”). Notwithstanding the foregoing, Landlord and Tenant agree that the number of usable and rentable square feet contained in the Premises initially leased by Tenant pursuant to this
Lease are as set forth in Section 6.2 of the Summary, and are not subject to remeasurement at any time, except pursuant to the terms of Section 1.3, above. The measurement of (i) any portion of the Premises remaining
after Tenant elects to downsize the Premises pursuant to the terms of Section 1.3 above, or (ii) the “First Offer Space,” as that term is defined in Section 1.6 of this Lease (collectively, the
“Measurable Space”), shall be measured pursuant to BOMA. The determination of the rentable square footage of the applicable Measurable Space shall be confirmed in writing between Landlord and Tenant. In the event of the addition of
the applicable Measurable Space, all amounts, percentages and figures appearing or referred to in the Lease based upon such addition of the rentable square footage shall be modified in accordance with such addition. 

1.5 Condition of the Premises. Tenant acknowledges that Landlord has made no representation or warranty, express or implied, regarding
the condition of the Real Property, or any part thereof, or the compliance of the Real Property, or any part thereof, with any applicable law, ordinance or governmental rule or regulation, except as specifically set forth in this Lease and in the
Tenant Work Letter, attached hereto as Exhibit B. Tenant hereby agrees that upon Landlord’s delivery to Tenant of the Premises, including the “Base Building,” as that term is defined in the Tenant Work Letter, Tenant
shall accept the Premises and possession thereof in its then “as-is” condition, subject to the terms of the Tenant Work Letter, and Landlord ,shall have no further obligation to make any alterations, improvements, additions or
modifications to the Base Building in connection with Landlord’s initial construction of the Premises, except as otherwise required pursuant to the terms of the Tenant Work Letter and this Lease. 

1.6 Right of First Offer. Tenant shall have an ongoing right of first offer during the Lease Term with respect to all of the space in
the Office Portion of the Building (the “First Offer Space”). Tenant’s right of first offer shall be on the terms and conditions set forth in this Section 1.6. The rights contained in this Section 1.6
shall not be personal to the Tenant originally named in this Lease and, accordingly, may be exercised by Tenant, its successors as tenant hereunder, or any permitted assignee of all tenant’s interest as tenant hereunder. 

1.6.1 Procedure for Offer. Landlord shall notify Tenant (the “First Offer Notice”) from time to time as soon as
Landlord determines that any portion of the First Offer Space will become available for lease to third parties provided, however, such notification shall be given not earlier than the date which is twelve (12) months before the actual date of
physical availability of such First Offer Space. Pursuant to such First Offer Notice, Landlord shall offer to lease to Tenant such First Offer Space. The First Offer Notice shall describe the space so offered to Tenant, shall set forth the
“First Offer Rent,” as that term is defined in this Section 1.6.1, below, and shall set forth the other terms upon which Landlord is willing to lease such space to Tenant. The rent payable by Tenant for the First Offer Space
(the “First Offer Rent”) shall be at the “Fair Market Rent” for the First Offer Space, as that term is defined in Section 2.2.1.3 of this Lease. Notwithstanding the foregoing, upon request by Tenant, Landlord
shall, within five (5) business days thereafter, provide to Tenant in writing a listing (the “Available Space List”) of the First Offer Space that is then available for leasing or which Landlord reasonably believes will become
available for leasing in the twenty-four (24) month period following the date of Tenant’s request, and such Available Space List shall set forth the existing term expiration date, the number of any renewal options and their respective
exercise mechanisms and dates, the term of any renewal options, and a description of the specific additional space rights relating to the First Offer Space, for each then existing lease. Thereafter, 

  
 3 

 
Tenant may request that Landlord deliver to Tenant a First Offer Notice as to any such First Offer Space on the Available Space List, and Landlord shall deliver a First Offer Notice within five
(5) business days of Tenant’s Notice. 
 1.6.2 Procedure for Acceptance. If Tenant wishes to exercise Tenant’s right
of first offer with respect to the space described in the First Offer Notice, then within fifteen (15) days of delivery of the First Offer Notice to Tenant, Tenant shall deliver notice to Landlord of Tenant’s intention to exercise its
right of first offer with respect to all or any portion Of the space described in the First Offer Notice on the terms contained in such notice. In the event that, concurrently with Tenant’s exercise of the first offer right, Tenant notifies
Landlord that it does not accept the First Offer Rent set forth in the First Offer Notice, the First Offer Rent shall be determined in accordance with the procedures set forth in Section 2.2.2 of this Lease; otherwise, the First Offer
Rent shall be as set forth in Landlord’s First Offer Notice. If Tenant does not so notify Landlord within the fifteen (15) day period of Tenant’s exercise of its first offer right, then Landlord shall be free to lease the space
described in the First Offer Notice to anyone to whom Landlord desires on any terms Landlord desires, for a period of one hundred eighty (180) days commencing upon the expiration of the fifteen (15) day period, after which time,
Tenant’s rights to such space under this Section 1.6 shall renew. 
 1.6.3 Amendment to Lease. If Tenant timely
exercises Tenant’s right to lease the First Offer Space as set forth herein, Landlord and Tenant shall within thirty (30) days thereafter execute an amendment to this Lease adding such First Offer Space to the then-existing Premises upon
the terms and conditions set forth in this Lease and as set forth in the First Offer Notice and this Section 1.6, provided that the term of the First Offer Space shall be coterminous with the Lease Term. 

ARTICLE 2 

INITIAL LEASE TERM: OPTION TERMS 

2.1 Initial Lease Term. The terms and provisions of this Lease shall be effective as of the date of this Lease except for the
provisions of this Lease relating to the payment of Rent. The term of this Lease (the “Lease Term”) shall be as set forth in Section 7.1 of the Summary and shall commence on the date (the “Lease Commencement
Date”) set forth in Section 7.2 of the Summary (subject, however, to the terms of Section 5 of the Tenant Work Letter), and shall expire on the date (the “Lease Expiration Date”) set forth in
Section 7.3 of the Summary, unless this Lease is sooner terminated as hereinafter provided. For purposes of this Lease, the term “Lease Year” shall mean each consecutive twelve (12) month period during the Lease Term
commencing on the Lease Commencement Date; provided that the last Lease Year shall end on the Lease Expiration Date. Notwithstanding the foregoing definition of the Lease Commencement Date for the Premises, if Tenant commences business operations
from any portion of the Premises or the Additional Space, as the case may be, prior to the occurrence of the Lease Commencement Date (each space occupied to be known as the “Pre-Occupancy Space”), all of the terms and conditions of
this Lease shall apply to that portion of the Premises containing the Pre-Occupancy Space, except that during the period commencing on the date Tenant commences business operations from the applicable Pre-Occupancy Space and continuing until the
Lease Commencement Date (the “Pre-Occupancy Period”), Tenant shall have no obligation to pay Base Rent (but shall be responsible for parking charges for all parking spaces used); provided that if Tenant occupies more than fifty
percent (50%) of the Premises for the purpose of conducting business in the Premises, then Tenant shall pay- to Landlord in accordance with the terms of Article 3, Base Rent for the Pre-Occupancy Space equal to the product of
(a)              Dollars (            ), and (b) the rentable square feet of the Pre-Occupancy Space. Tenant shall have
the right to commence business operations from any portion of the Premises during the Pre-Occupancy Period, provided that a certificate of occupancy or its equivalent permitting occupancy shall have been issued by the appropriate governmental
authorities for the Pre-Occupancy Space. Notwithstanding anything to the contrary contained herein, Tenant shall be responsible to pay “Tenant’s Share” of “Direct Expenses,” as those terms are defined in Section 4.1 of
this Lease, during June, 1997. 
 2.1.1 Delivery of the Premises. Including Base Building, to Tenant. The date (the “Delivery
Date”) upon which Landlord shall deliver the Premises, including the completed “Base Building,” as that term is defined in Section 1.1 of the Tenant Work Letter with the

  
 4 

 
“Demolition” completed pursuant to the “Demolition Plan,” as set forth in Section 1.2 of the Tenant Work Letter, to Tenant shall be on or before March 1, 1997. 

2.1.2 Existing Tenants Occupying Premises. Tenant acknowledges that portions of the Premises are currently occupied by General Services
Administration (“GSA”), the Goldman Law Firm and Taggert & Hawkins (collectively, the “Existing Tenants”) and each Existing Tenant has agreed with Landlord to vacate the Premises, and/or cause any of its
Subtenants or business affiliates to vacate the Premises, on or before February 1, 1997. Accordingly, Landlord’s ability to deliver the Premises to Tenant is subject to the surrender of such portions of the Premises by each such Existing
Tenant. If Landlord, for any reason whatsoever (including the failure of an Existing Tenant to surrender its premises), cannot cause the Delivery Date to occur by March 1, 1997, and, if applicable, taking into account that GSA is a government
agency, Landlord shall use its commercially reasonable efforts to ensure that the Existing Tenant vacates its premises as soon as possible after February 1, 1997, and upon Tenant’s request, Landlord shall deliver to Tenant evidence which
demonstrates that Landlord is using such commercially reasonable efforts to ensure the vacation of its premises by the Existing Tenant. 

2.1.3 Monetary Penalties For Failure to Timely Delivery the Base Building. If Landlord does not cause the Delivery Date to occur by
March 1, 1997, then for every day that Landlord fails to cause the Delivery Date to occur by March 1, 1997, Tenant shall receive a Base Rent credit equal to two (2) days of Base Rent; provided, however, Tenant shall not receive a Base
Rent credit pursuant to this Section 2.1.3 in excess of (            ). 

2.1.4 Termination Penalties For Failure to Timely Delivery the Premises. If the Delivery Date does not occur by March 1, 1997,
then Tenant shall have the right to deliver a notice to Landlord (a “Termination Notice”) electing to terminate this Lease effective upon the date occurring five (5) business days following receipt by Landlord of the
Termination Notice. The effectiveness of any such Termination Notice delivered by Tenant to Landlord shall be governed by the terms of this Section 2.1.4. Upon any termination as set forth in this Section 2.1.4, Landlord and
Tenant shall be relieved from any and all liability to each other resulting hereunder, except that after the termination of this Lease, Landlord shall be liable to Tenant for any and all out-of-pocket costs (provided Tenant delivers to Landlord
reasonable evidence of such costs) in connection with (i) the preparation, negotiation and documentation of this Lease, (ii) the design and construction of the Tenant Improvements, and (ii) any penalty fees or costs, or any other
monetary payments required to be paid to the existing landlord under that certain lease between Tenant and such existing landlord for space at Three Embarcadero Center, San Francisco, as a result of Tenant’s holding over in such space past the
expiration date of the same (collectively, “Tenant’s Holdover Costs”); provided, however, Landlord shall not be liable for Tenant’s Holdover Costs in excess of
             Dollars (            ). 

2.2 Option Terms. 
 2.2.1
Option Rights. Tenant shall have two (2) options to extend the Lease Term for a period of five (5) years each (the “First Option Term” and the “Second Option Term,” respectively), which options
shall be exercisable by notice delivered by Tenant to Landlord as provided below. The First Option Term and Second Option Term are sometimes individually or collectively referred to in this Lease as the “Option Term.” Upon the
proper exercise of each such option to extend, the initial Lease Term or First Option Term, as applicable, shall be extended by the Option Term, subject to every term and condition of this tease, except that the applicable “Option Rent,”
as that term is defined in Section 2.2.1.3, below, shall be determined as set forth in Section 2.2.1.3, below. Tenant shall have the right, exercisable concurrently with Tenant’s delivery of the “Option
Notice,” as that term is defined below, to reduce the number of rentable square feet of office space which Tenant shall rent during the ensuing Option Term; provided, however, that Tenant may only reduce the size of the Premises in full floor
increments (or so much of a floor as shall be leased by Tenant in the event of less than full floor leasing) (the “Renewal Space”). Tenant shall incur no penalty or charge in connection with the reduction in the size of the Premises
during the ensuing Option Term. 
 2.2.1.1 Exercise of Options. Subject to the terms of this Section 2.2.1.1, each
option shall be exercised by Tenant in the following manner: (i) Tenant shall deliver notice to Landlord (the “Option Interest Notice”) not less than three hundred thirty 

  
 5 

 
(330) days prior to the expiration of the initial Lease Term or the First Option Term, as the case may be (the “Option Interest Notice Outside Date”), stating that
(A) Tenant is interested in exercising its option and (B) the number of rentable square feet of the Premises, subject to the limitations set forth in Section 2.2.1, above, which Tenant desires to lease during such Option Term;
(ii) Landlord shall, after receipt of the Option Interest Notice, deliver notice (the “Option Rent Notice”) to Tenant not less than three hundred (300) days prior to the expiration of the initial Lease Term or the First
Option Term, as the case may be (the “Option Rent Notice Outside Date”), setting forth the proposed “First Option Rent” or the proposed “Second Option Rent,” as those terms are defined in Section 2.2.1.2
below, as the case may be, which shall be applicable to this Lease during the applicable Option Term, and (iii) (A) Tenant may, at its option, on or before the date occurring two hundred seventy (270) days prior to the expiration of
the initial Lease Term or the First Option Term, as the case may be (the “Arbitration Notice Outside Date”), deliver a notice to Landlord (the “Fair Market Rent Arbitration Notice”), pursuant to which Fair Market
Rent Arbitration Notice, Tenant may object to the proposed Option Rent or request the determination of Option Rent, if no Option Rent Notice was given because Tenant did not give the Option Notice, in either of which cases the parties shall follow
the procedure, and the applicable Option Rent shall be determined, as set forth in Section 2.2.2 of this Lease, or (B) to the extent the terms of Section 2.2.2, below, are inapplicable (since Tenant did not deliver the
Fair Market Rent Arbitration Notice), if Tenant wishes to exercise its extension option on the terms set forth in the Option Rent Notice, Tenant shall, on or before the date occurring two hundred seventy (270) days prior to the expiration of
the initial Lease Term or the First Option Term, as the case may be (the “Exercise Notice Outside Date”), exercise the option by delivering notice thereof to Landlord (the “Option Exercise Notice”). Notwithstanding
the foregoing terms of this Section 2.2.1.1, if the Renewal Space Tenant desires to lease during either Option Term consists of less than two (2) full floors, then for purposes of Tenant exercising its options to extend the
applicable Option Term, the outside dates set forth above shall refer to the following outside dates: (a) the Option Interest Notice Outside Date shall instead mean not less than four hundred twenty-five (425) days prior to the expiration
of the initial Lease Term or the First Option Term, as the case may be; (b) the Option Rent Notice Outside Date shall mean not less than three hundred ninety-five (395) prior to the expiration of the initial Lease Term or the First Option
Term as the case may be; and (c) the Arbitration Notice Outside Date or the Exercise Notice Outside Date shall mean three hundred sixty-five (365) prior to the expiration of the initial Lease Term or the First Option Term, as the case may
be. In the event Tenant fails to exercise its right to extend the Lease Term for the First Option Term or Second Option Term within the applicable time periods specified above, Tenant’s option rights as set forth in this
Section 2.2.1.1 shall be terminated, and Tenant shall have no further rights pursuant to the terms of this Lease to extend the Lease Term. 

2.2.1.2 Termination of Option Rights. Notwithstanding anything to the contrary contained herein, Tenant shall not be allowed to
exercise an option right and an Option Term shall not commence pursuant to the terms of this Section 2.2, if at the time Tenant gives Landlord the Option Exercise Notice, or the time the Option Term commences, as the case may be, Tenant is in
material default or monetary default of this Lease pursuant to the terms of Section 19.1 below, after the giving of notice to Tenant by Landlord and the expiration of all applicable cure periods. 

2.2.1.3 Option Rent. The rent payable by Tenant during the First Option Term (the “First Option Rent”), or the Second
Option Term (the “Second Option Rent”), as the case may be (collectively, the “Option Rent”), shall be equal to the then “Fair Market Rent.” “Fair Market Rent,” as used in this Lease,
shall be equal to (a) ninety-five percent (95%) of the face or stated rental rate and (b) one hundred percent (100%) of the other economic terms at which tenants comparable to Tenant, as of the first day of the applicable Option
Term, are leasing for a comparable term, non-renewal, non-equity space comparable in size to the Premises, Renewal Space, First Offer Space or “Management Office,” as that term is defined in Section 4.2.4 (38) of this Lease, as
applicable, from a willing, comparable landlord, at arm’s length, which comparable space is located in the “Comparable Buildings,” as that term is defined in Section 29.18, below, taking into consideration the following factors
and all tenant concessions and inducements including one hundred percent (100%) of the following concessions (which concessions Tenant, at its option, may take in the form as set forth below, or on an in-lieu cash up-front basis of the same
value as the concession): (i) the amount of protection received by tenants in connection with the payment of operating and tax expenses (i.e, – base year or expense stop), (ii) rental abatement concessions being given such
tenants, if any, in 

  
 6 

 
connection with such comparable space and, as to First Offer Space only, in connection with the period of construction of such space, (iii) tenant improvement allowances and the value of
tenant improvement work provided or to be provided for such comparable space, provided that there shall be deducted from any such comparable space allowance or tenant improvement value, and Landlord shall receive credit for, the value of the then
existing improvements, if any, in the Premises, Renewal Space or the First Offer Space, as applicable, regardless of whether the same were paid for or installed by Landlord or Tenant, with such value to be based upon the age, quality and layout of
the improvements and the extent to which the same could be utilized by a general office user (the “Existing Improvements Value”); provided, however, for purposes of this item (iii) only, the Existing Improvements Value shall
not exceed the “Tenant Improvement Cost,” as that term is defined in Section 3.4.1, below, (iv) all other tenant inducements and landlord concessions and payments, including, but not limited to, lease takeover payments, if any,
being granted such tenants in connection with such comparable space, and real estate brokerage commissions (which shall be paid to the applicable broker or to Tenant if Tenant does not utilize the services of a broker in connection with such
extension), (v) the time the particular rental rate under consideration was agreed upon and became or is to become effective, (vi) the ratio of rentable square feet to usable square feet, (vii) whether the lease transaction in
question grants to the tenant any protection from increases in any component or all of real property taxes and operating expenses, and if so, the amount or value thereof, and (viii) any other material factor, benefit or burden which a
sophisticated tenant or landlord would believe would have a material impact on a determination of the current Fair Market Rental. 
 2.2.2
Arbitration of Fair Market Rent. If the determination of Fair, Market Rent is appropriately submitted to arbitration, Landlord and Tenant shall each appoint one arbitrator who shall by profession be a real estate broker who shall have been
active over the five (5) year period ending on the date of such appointment in the leasing of commercial high-rise properties in San Francisco, California. The determination of the arbitrators shall be limited solely to the issue of determining
the actual Fair Market Rent for the applicable space, taking into account the requirements of Section 2.2.1.3. Each such arbitrator shall be appointed within fifteen (15) days after Landlord’s receipt of the Fair Market Rent
Arbitration Notice by each party delivering notice of its appointment to the other party. 
 2.2.2.1 The two arbitrators so appointed shall
within ten (10) days of the date of the appointment of the last appointed arbitrator agree upon and appoint a third arbitrator who shall be qualified under the same criteria set forth hereinabove for qualification of the initial two
(2) arbitrators. 
 2.2.2.2 The three arbitrators shall within thirty (30) days of the appointment of the third arbitrator reach
a decision as to the actual Fair Market Rent and shall notify Landlord and Tenant thereof. 
 2.2.2.3 The decision of the majority of the
three arbitrators shall be the decision of the arbitrators and shall be binding upon Tenant and Landlord. 
 2.2.2.4 If either Landlord or
Tenant fails to appoint an arbitrator .within fifteen (15) days after Landlord’s receipt of the Fair Market Rent Arbitration Notice, the arbitrator appointed by one of them shall reach a decision, and shall notify Landlord and Tenant
thereof Such arbitrator’s decision shall be binding upon Tenant and Landlord. 
 2.2.2.5 If the two arbitrators fail to agree upon and
appoint a third arbitrator, or both parties fail to appoint an arbitrator, then the appointment of the third arbitrator or any arbitrator shall be dismissed and the matter to be decided shall be forthwith submitted to the arbitration procedures set
forth in Article 24 of this Lease. Such decision shall be binding on Tenant and Landlord. 
 2.2.2.6 The cost of arbitration shall
be paid by Landlord and Tenant equally. 
 2.2.2.7 If the amount of the Fair Market Rent is not determined within the time periods set
forth above in this Section 2.2.2, and continues to be undetermined as of the commencement of the First Option Term or Second Option Term, as applicable, then tenant shall continue to pay the existing Base Rent for the applicable Renewal
Space until the amount of the Fair Market Rent is determined. When such determination is made, if Tenant has underpaid the 

  
 7 

 
amount of Base Rent for the Option Term, then Tenant shall pay such deficiency to Landlord with Tenant’s payment of its next installment of Base Rent, of if Tenant has overpaid such Base
Rent, then Landlord shall either, at Landlord’s option, credit such overpayment in full against Tenant’s payment of Base Rent next coming due hereunder or pay such overpayment to Tenant upon demand. 

ARTICLE 3

Section 4.1 of this Lease, and all other payments, disbursements, or reimbursements that are attributable to, payable by or the responsibility of Tenant under this Lease shall constitute “Rent” for all purposes of this
Lease and shall be payable and recoverable as Rent in the manner provided in this Lease. Tenant shall pay all Rent required under this Lease within the applicable time limits set forth in this Lease; and if no such time period is elsewhere specified
herein for payment of a particular amount, then such amount shall be paid within thirty (30) days after Landlord’s delivery of an invoice or demand therefor. All Rent shall be paid by Tenant to Landlord in lawful money of the United States

from time to time designate by thirty (30) days prior written notice to Tenant. Any Rent payable to Landlord by Tenant for any fractional month shall be prorated based upon the actual number of days in such calendar month. 

3.3 Interest on Late Payments. If Landlord does not receive a payment of any Rent within ten (10) days after notice that such
payment is due, then Tenant shall pay to Landlord interest on such amount equal to the lesser of (i) the per annum rate of two percent (2%) above the rate of interest publicly announced from time to time by Bank of America NT&SA (or
any successor bank thereto) at its San Francisco headquarters as its “Reference Rate” for commercial borrowing (or its then current equivalent publicly announced rate of interest), and changes in such rate shall be effective immediately
upon the public announcement of such change, or (ii) the maximum interest rate allowed by law (the “Interest Rate”). Such interest shall begin to accrue as of such thirtieth (30th) day after notice that such Rent payment
became due.

Right”) to reimburse Tenant for the “Tenant Costs,” as that term is defined below. “Tenant Costs” shall mean the sum of (i) the cost of the Tenant Improvements (which shall be deemed equal to Dollars
             ($         ) per rentable square foot of the Premises) (the “Tenant Improvement Cost”), and (ii) the total amount
of the “Commissions,” as that term is defined in Section 29.25.1 of this Lease paid by Tenant to the Broker (which shall be deemed equal to Dollars              ($
        ) per rentable square foot of the Premises). Landlord shall give Tenant notice (the “Reimbursement Notice”) that Landlord exercises the Reimbursement Right effective as of the first
day of the second (2nd) month following the date of delivery of the Reimbursement Notice to Tenant (the “Effective Date”), the Base Rent shall be increased to equal $         per rentable
square foot, and Landlord shall pay Tenant on the Effective Date an amount equal to the “Unamortized Value” as that term is defined in Section 3.4.2, below, as of the Effective Date of the Tenant Costs. 

3.4.2 Calculation of Unamortized Value. The “Unamortized Value” of the Tenant Costs shall be equal to the product of
(i) Dollars              ($         ) per rentable square foot of the Premises and (ii) a fraction in which the numerator is (A) the
number of months remaining in the Lease Term as of one of the following dates, as applicable: (a) the Effective Date, (b) the date, if any, Tenant terminates Lease pursuant to Section 11.2, below (the

(1st) year of the initial Lease Term, Tenant shall pay as additional rent “Tenant’s Share” of the annual “Direct Expenses,” as those terms are defined in Sections 4.2.7 and 4.2.2 of this Lease, respectively,
which are in excess of the amount of Direct Expenses attributable to the “Base Year,” as that term is defined in Section 4.2.1 of this Lease. Such additional rent, together with any and all other amounts payable by Tenant to
Landlord pursuant to the terms of this Lease (other than Base Rent and any Security Deposit), shall be hereinafter collectively referred to as the “Additional Rent.” All amounts due under this Article 4 as Additional Rent
shall be payable for the same periods and in the same manner, time and place as the Base Rent. Without limitation on other obligations of Tenant which shall survive the expiration of the Lease Term, the obligations of Landlord and Tenant provided
for in this Article 4 shall survive the expiration of the Lease Term, to the extent the same is attributable to the time period prior to the expiration of the Lease Term. 

4.2 Definitions. As used in this Article 4, the following terms shall have the meanings hereinafter set forth: 

4.2.1 “Base Year” shall mean the period set forth in Section 9.1 of the Summary. 

4.2.2 “Direct Expenses” shall mean “Operating Expenses” and “Tax Expenses.” 

4.2.3 “Expense Year” shall mean each calendar year in which any portion of the Lease Term falls, through and including the
calendar year in which the Lease Term expires. 
 4.2.4 “Operating Expenses” shall mean all reasonable and actually
incurred expenses, costs and amounts of every kind and nature which Landlord shall pay during any Expense Year because of or in connection with the ownership, management, maintenance, repair, restoration or operation of the Real Property and the
provision of services to Tenant and other occupants of the Building, including, without limitation, any amounts paid for (i) the cost of supplying all utilities, heating, cooling, ventilation and fuel, the cost of operating, maintaining,
repairing and managing the utility systems, mechanical systems, sanitary and storm drainage systems, and escalator and elevator systems, and the cost of supplies and equipment and maintenance and service contracts in connection therewith;
(ii) the cost of licenses, certificates, permits and inspections and the cost of contesting the validity or applicability of any governmental enactments which may affect Operating Expenses, and the costs incurred in connection with the
implementation and operation of a governmentally mandated transportation system management program or similar program; (iii) the cost of insurance carried by Landlord; (iv) the cost of landscaping maintenance, relamping, and all supplies,
tools, equipment and materials used in the operation, repair and maintenance of the Building; (v) fees, charges and other costs, including consulting fees, legal fees and accounting fees, of all contractors engaged by Landlord or otherwise
reasonably incurred by Landlord in connection with the management, operation, maintenance and repair of the Building and Real Property; (vi) any equipment rental agreements or management agreements for the Building; (vii) wages, salaries
and other compensation and benefits of all persons engaged in the operation, management, maintenance or security of the Building, and employer’s Social Security taxes, unemployment taxes or insurance, and any other taxes which may be levied on
such wages, salaries, compensation and benefits; provided, that if any employees of Landlord provide services for more than one building of Landlord, then a prorated portion of such employees’ wages, benefits and taxes shall be included in
Operating Expenses based on the portion of their working time devoted to the Building; (viii) operation, repair, testing and maintenance of all “Systems and Equipment,” as that term is defined in Section 4.2.5 of this
Lease, and components thereof; (ix) the cost of janitorial service, alarm and security service, governmentally mandated health and safety programs, window cleaning, trash removal; (x) amortization (including interest at Landlord’s
actual cost, on the unamortized cost) of the cost of acquiring or the rental expense of personal 

  
 9 

 
property used in the maintenance, operation and repair of the Building and Real Property; (xi) the cost of capital improvements or other costs incurred in connection with the Real Property
which are (A) required under any law which is enacted after the Lease Commencement Date, or (B) reasonably intended to reduce Operating Expenses, provided that such costs shall be included in Operating Expenses only to the extent of the
reasonably anticipated reduction of Operating Expenses for that particular Expense Year caused by such capital improvement only to the extent that such reduction is reasonably anticipated by Landlord at the time of such expenditure to be incurred in
connection therewith, and provided further that each such capital expenditure shall be amortized over its reasonable useful life and the unamortized cost of the same shall bear interest at the Landlord’s actual cost of funds; and (x) all
other costs and expenses that under sound real property accounting and management practices would be included in Operating Expenses as such practices are applied at the Comparable Buildings. Notwithstanding anything to the contrary set forth herein,
for any Expense Year in which less than ninety-five percent (95%) of the rentable space in the Building is leased during the entire Expense Year, all “Variable Components,” as that term is defined in this Section 4.2.4,
below, of Operating Expenses for such Expense Year shall be grossed-up (or grossed-down, as applicable), employing sound accounting and property management principles, to the amount such Variable Components would have been in the event the Building
had been ninety-five percent (95%) leased during the entire Expense Year and the adjusted amount of the Variable Components shall be used in determining Operating Expenses for such Expense Year. Such adjustment, however, shall not result in
Landlord receiving from Tenant and other tenants in connection with the Variable Components more than one hundred percent (100%) of the cost of such Variable Components. “Variable Components” shall be those components that vary
based upon occupancy levels and shall specifically exclude Fixed Costs. “Fixed Costs” means (a) Tax Expenses charged against all portions of the Building other than Tax Expenses charged against tenant improvements (which tenant
improvements do not include the Base Building), (b) premiums incurred by Landlord for liability insurance and property damage insurance relating to Landlord’s ownership and/or operation of the Building, (c) landscaping costs relating

(4) With the exception of any deductible amount, not to exceed Twenty-Five Thousand and No/100 Dollars ($25,000.00) in any particular Expense
Year, under the insurance policy required to be carried by Landlord as described in Section 10.2.1 of this Lease, costs incurred by Landlord, including for the repair of damage to the Building, pursuant to the terms of Article 11 of this
Lease or otherwise, in connection with any type of casualty or event of damage and destruction;

negotiations and transactions with present or prospective tenants or other occupants of the Building;

of space or occupancy agreement in the Building;

and/or services rendered by unaffiliated third parties on a competitive basis in Comparable Buildings; 
 (12) interest, principal,
attorneys’ fees, environmental investigations or reports, points, fees and other lender costs and closing costs on debts or amortization on any mortgage or mortgages or any other debt instrument encumbering the Building or any part thereof or

to accounting, payroll, legal and computer services which are partially or totally rendered in locations outside the Building;

prorated to reflect time spent on operating, accounting, managing, maintaining and repairing the Building vis-a-vis time spent on matters unrelated to the same; provided Operating Expenses shall in no event include salaries of individuals who hold a
position which is generally considered to be higher in rank than the position of the manager of the Building or the chief engineer of the Building;

annual premium resulting from any new forms of insurance (including converting from a blanket to single-asset policy), any increase in insurance limits or coverage, or any decrease in deductibles in any year after the Base Year, shall be deemed to

(“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 Building’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. It is the intention of Tenant and Landlord that all such new and increased assessments, taxes, fees, levies, and charges and all similar assessments, taxes, fees, levies and charges be included within the definition of Tax Expenses for
purposes of this Lease; 
 (iii) Any assessment, tax, fee, levy, or charge allocable to or measured by the area of the Premises or the rent

	Year 1:	  	Year 6:
		
	Year 2:	  	Year 7:
		
	Year 3:	  	Year 8:
		
	Year 4:	  	Year 9:
		
	Year 5:	  	Year 10:

 4.2.7 “Tenant’s Share” shall mean the percentage set forth in Section 9.2 of the
Summary. Tenant’s Share was calculated by multiplying the number of rentable square feet of the Premises by 100 and dividing the product by the total rentable square feet in the Building. In the event either the rentable square feet of the
Premises and/or the total rentable square feet of the Building is changed pursuant to the terms of this Lease, Tenant’s Share shall be appropriately adjusted, and, as to the Expense Year in which such change occurs, Tenant’s Share for such
year shall be determined on the basis of the number of days during such Expense Year that each such Tenant’s Share was in effect. 

4.3 Calculation and Payment of Additional Rent. 

4.3.1 Calculation of Excess. If for any Expense Year ending or commencing within the Lease Term, Tenant’s Share of Operating
Expenses for such Expense Year exceeds Tenant’s Share of the Operating Expenses attributable to the Base Year, then Tenant shall pay to Landlord, in the manner set forth in Section 4.3.2, below, and as Additional Rent, an amount equal to
the excess (the “Excess”). 
 4.3.2 Statement of Actual Operating Expenses and Payment by Tenant. Landlord shall
give to Tenant on or before the first day of April following the end of each Expense Year or as soon thereafter as is practicable, a statement (the “Statement”) which shall state the Operating Expenses incurred or accrued for such
preceding Expense Year, and which shall indicate the amount, if any, of any Excess. The Statement shall be certified by an officer of Landlord. Upon receipt of the Statement for each Expense Year ending during the Lease Term, if an Excess is
present, Tenant shall pay within thirty (30) days after delivery 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 4.3.3, below. If the amount of Tenant’s Share of Operating Expenses is less than the amount paid by Tenant as Estimated Excess during the applicable Expense Year (an “Overpayment”), Landlord shall either
promptly refund the amount of the Overpayment to Tenant or credit such Overpayment in full against Tenant’s payment of Additional Rent next coming due hereunder. The failure of Landlord to timely furnish the Statement for any Expense Year shall
not prejudice Landlord from enforcing its rights under this Article 4. Even though the Lease Term has expired and Tenant has 

  
 16 

 
vacated the Premises, when the final determination is made of Tenant’s Share of the Operating Expenses for the Expense Year in which this Lease terminates, (i) if an Excess is present,
Tenant shall within thirty (30) days after delivery of the Statement pay to Landlord an amount as calculated pursuant to the provisions of Section 4.3 of this Lease, or (ii) if an Overpayment is present, Landlord shall within thirty
(30) days after delivery of the Statement pay to Tenant the amount of the Overpayment. The provisions of this Section 4.3.2 shall survive the expiration or earlier termination of the Lease Term. 

4.3.3 Statement of Estimated Operating Expenses. Prior to the commencement of each Expense Year or as soon thereafter as practicable,
Landlord shall notify Tenant of the estimated monthly amount of Tenant’s Share of Operating Expenses (the “Estimate”) payable by Tenant as Additional Rent for such Expense Year (the “Estimate Statement”),
provided that the Estimate, as it relates to Operating Expenses, shall not exceed one hundred five percent (105%) of the Operating Expenses for the prior Expense Year (the “105% Cap”) unless Landlord also supplied Tenant with a
commercially reasonable explanation of such excess. Tenant shall pay Landlord the Estimate at the same time as and together with Tenant’s payment of Base Rent, Tenant shall continue to pay Additional Rent on the basis of the prior Expense
Year’s Estimate Statement until such notice is given, at which time any necessary adjustments for prior payments made during such year shall be made based upon Landlord’s then current Estimate Statement based upon Landlord’s actual or
projected Operating Expenses for such Expense Year, and subsequent monthly payments of the Estimate as Additional Rent shall be based upon such revised Estimate Statement. 

4.4 Allocation of operating and Tax Expenses. In accordance with the terms of this Section 4.4, Landlord shall allocate the
operating and tax costs for the Project among the “Cost Pools,” as that term is defined below. The “Cost Pools” shall be: (i) the Apartment Portion, (ii) the Two Rincon Office Portion, (iii) the Two Rincon
Retail Portion (iv) the One Rincon Office Portion, and (v) the One Rincon Retail Portion. To the extent operating or tax costs are directly and solely attributable to a specific Cost Pool, such operating or tax costs will be charged
directly to such Cost Pool. To the extent operating or tax costs are attributable and allocable to two or more Cost Pools, such Operating Expense will be prorated on a square footage basis amongst such Cost Pools, and therefore, only operating or
tax costs attributable to the Two Rincon Office Portion shall be part of Operating Expenses or Tax Expenses. To the extent operating or tax costs are common to all Cost Pools, such Operating Expense will be allocated among the Cost Pools in
accordance with the following percentages: (a) Apartment Portion – 30.52%, (b) Two Rincon Office Portion – 27.78%, (c) Two Rincon Retail Portion – 3.05%, (d) One Rincon Office Portion – 32.54%, and
(e) One Rincon Retail Portion – 6.11%. The allocation of operating and tax costs between Cost Pools shall be made on an equitable and reasonable basis and in a manner consistent between the Base Year and any subsequent Expense Year. 

4.5 Tenant’s Payment of Earthquake Insurance Premiums. Tenant shall pay Tenant’s Share of the amount allocated to the Two
Rincon Office Portion Cost Pool with respect to any earthquake insurance carried by Landlord in accordance with the terms of Section 10.2.3 of this Lease (“Tenant’s Earthquake Insurance Contribution”) upon the later to
occur of (i) thirty (30) days after notice of such amount by Landlord to Tenant, and (ii) five (5) days before the due date of the applicable invoice therefor. 

4.6 Landlord’s Books and Records: Tenant Audit. 

4.6.1 In connection with the delivery of each Statement and Estimate Statement, Landlord shall provide to Tenant substantial detail of the
calculations of the Operating Expenses, or of the amounts charged, as the case may be. Landlord shall provide, by account and subaccount, the total Operating Expenses and all adjustments corresponding thereto. Landlord shall also provide in
reasonable detail the calculation of Tenant’s Share of the Operating Expenses as such calculations are delineated in the Lease. During the Lease Term, as the same be extended, Tenant or an agent designated by Tenant (the “Outside
Agent”), may, after reasonable notice to Landlord and at reasonable times, inspect, review, audit, and/or copy Landlord’s records relating to Operating Expenses or of the amounts charged, as the case may be, and the operation,
maintenance, repair and management of the Building at Landlord’s offices, which offices shall be located in the City of San Francisco. Landlord shall be obligated to keep such records for all Lease Years associated with this Lease until two
(2) years following the termination of the Lease. If an audit, review or inspection by an Outside Agent or by Tenant 

  
 17 

 
alleges an overbilling, Tenant may submit a claim for the overbilled amount to Landlord, detailing the nature of the overbilling, and Landlord shall have thirty (30) days to pay such amount
or contest the claim by giving notice thereof to Tenant, detailing the nature of Landlord’s contest of Tenant’s claims. If Landlord timely and effectively contests the claim, either Landlord or Tenant may submit the claim to the
arbitration procedures set forth in Article 24 of this Lease. If (i) the claim is not timely and effectively contested by Landlord, or (ii) if Landlord has timely and effectively contested Tenant’s claim and the arbitration shall
disclose that Tenant has been overbilled by five percent (5%) of Tenant’s Share of Additional Rent as reflected in the Statement or of the amounts charged, as the case may be (such number to be known as the “Threshold
Number”) then in any case, Landlord shall pay the reasonable cost of the audit, review or inspection charged by an Outside Agent to Tenant and the costs of the arbitration within thirty (30) days after delivery to Landlord of demand
therefor and Landlord shall pay to Tenant the amount of any overbilling, if any, within thirty (30) days after the date of determination thereof If the arbitration shall disclose that Tenant was not overbilled by more than the Threshold Number,
Tenant shall pay the cost of such arbitration. The results of any inspection, review, and/or audit of the Operating Expenses by or on behalf of any other tenant or other party, which inspection, review, and/or audit is possessed by Landlord or
available to Landlord and demonstrates that an error in the calculation of the Operating Expenses was made by Landlord, shall be delivered to Tenant and Tenant shall automatically receive a corresponding adjustments to Tenant’s Share of
Operating Expenses. Landlord and Tenant hereby agree that any determinations of particular issues by the arbitrator which have application to future Expense Years shall be deemed determinative of such issues for the future Expense Years. 

4.6.2 Landlord shall have the right to recover from Tenant the amount of Tenant’s Share of any Operating Expenses attributable to a
Expense Year, but paid in a subsequent Expense Year; provided, however, that except as set forth below in this Section 4.6.2, Landlord may only adjust the Operating Expenses for any given Expense Year within two (2) years after the
expiration of such Expense Year. Notwithstanding the foregoing, Landlord may adjust Operating Expenses more than two (2) years after the expiration of any given Expense Year in connection with Tax Expenses or other governmental or public sector
charges (including, but not limited to, utility charges) first billed to Landlord after such two (2) year period but which relate to Operating Expenses for such Expense Year. 

4.7 Non-Waiver of Rights. Except as provided in Section 4.6.2, no failure or determination of Landlord in anyone year to include
or exclude certain items in its computation of Operating Expenses or to invoice Tenant for the full amount of Tenant’s Share of Operating Expenses shall be construed as depriving Landlord of the right to include such items of Operating Expenses
or to invoice Tenant for the fun amount of Tenant’s Share thereof in any subsequent year in strict accordance with the provisions of Article 4. 

ARTICLE 5 

USE OF PREMISES 

5.1 Permitted Use. Tenant shall use the Premises for general office purposes and any other legally permitted, non-retail,
uses consistent with the character of the Building as a first-class office building, and Tenant shall not use or permit the Premises to be used for any other purpose or purposes whatsoever without the prior written consent of Landlord, which consent
may be withheld in Landlord’s sole and absolute discretion. In connection with, and incidental to, Tenant’s use of the Premises Tenant, at its sole cost and expense and upon compliance with all applicable laws, may install
“dryer” or similar units, microwave or convection ovens, kitchenettes, dishwashers and an executive dining facility (provided same do not require a modification to the Building’s certificate of occupancy) in the Premises for the
purpose of warming or re-heating food for the employees and business guests of Tenant (but not for use as a public restaurant or private cafeteria or for cooking), provided that Tenant shall obtain all permits required by any governmental
authorities for the operation thereof and such installation shall comply with the provisions of this Lease, including, without limitation, Article 8 of this Lease. Tenant may also install, at its sole cost and expense and subject to and in
compliance with the provisions of Article 8 of this Lease, vending machines for the exclusive use of the officers, employees and business guests of Tenant, each of which vending machines (if it dispenses any beverages or other liquids or
refrigerates) shall have a waterproof pan located thereunder or refrigerant recovery system connected to a drain. 

  
 18 

 5.2 Prohibited Uses. Tenant further covenants and agrees that it shall not use, or
suffer or permit any person or persons to use, the Premises or any part thereof for any use or purpose contrary to the provisions of Exhibit D, attached hereto (the “Rules and Regulations”). Tenant shall not at any
time use or occupy knowingly or allow any person to use or occupy the Premises or the Building or do or knowingly permit anything to be done or kept in the Premises or the Building or perform any other action in any manner which: (i) violates
any agreement relating to the Building or any certificate of occupancy in force for the Premises, or the Building; (ii) causes or is likely to cause damage to the Building, the Premises or any equipment, facilities or other systems therein; or
(iii) interferes with the transmission or reception of microwave, television, radio or other communications signals by antennae located on the roof of the Building or elsewhere in the Building. Tenant shall not use or allow another person or
entity to use any part of the Premises for the storage (no matter how temporary), use, treatment, analysis, manufacture or sale of any “Hazardous Materials,” as that term is defined in Section 29.33, below. Landlord
acknowledges, however, that Tenant will maintain products in the Premises which are incidental to the operation of its offices, such as photocopy supplies, secretarial supplies and limited janitorial supplies, which products contain chemicals which
are categorized as Hazardous Materials. Landlord agrees that the use of such products in the Premises in compliance with all applicable laws and in the manner in which such products are designed to be used shall not be a violation by Tenant of this
Section 5.2. 
 ARTICLE 6 

SERVICES AND UTILITIES 

6.1 Standard Tenant Services. Landlord shall provide the following services on all days during the Lease Term unless otherwise stated
below. 
 6.1.1 Subject to all governmental rules, regulations and guidelines applicable thereto, Landlord shall provide heating,
ventilating and air conditioning (“HVAC”) from Monday through Friday, during the period from 6:00 a.m. to 6:30 p.m. and on Saturday during the period from 9:00 a.m. to 1:00 p,m., except for the date of observation of New Year’s
Day, President’s Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, Christmas Day and any other nationally enacted and observed holiday (collectively, the “Holidays”). Landlord represents that the HVAC equipment
in the Building (the “Building HVAC System”) is designed to perform in accordance with the HVAC specifications attached to this Lease as Exhibit H (the “HVAC Specifications”). Landlord shall use
reasonable efforts to cause the Building HVAC System to perform in accordance with the HVAC Specifications at all times that HVAC is required to be provided under this Lease, provided that Tenant uses the Building engineer to review Tenant’s
HVAC design and such engineer reasonably approves Tenant’s HVAC design. Tenant shall have the right, at Tenant’s sole expense, to install, maintain and replace a private HVAC system or systems (the “Tenant HVAC System”)
separate from the Building HVAC System, in Tenant’s computer rooms, user rooms and other areas contained wholly within the Premises, provided that such Tenant HVAC System does not materially interfere with the operation, maintenance, or
replacement of the Building HVAC System. 
 6.1.2 Landlord shall at all times provide electricity to the Premises (including adequate
electrical wiring and facilities for connection to Tenant’s lighting fixtures and other equipment) for lighting and power suitable for the use of the Premises up to ten (10) watts per rentable square foot demand load on a continuous annualized
basis (the “Available Electricity”). Such electrical usage, to the extent the same exceeds seven (7) watts per rentable square foot of the Premises connected load on a continuous, annualized basis shall be known as “Excess
Consumption.” The amount of Excess Consumption used within the Premises must be verifiable by meters or submeters, purchased by Tenant at its expense. Landlord shall charge Tenant for its Excess Consumption at Landlord’s actual average
cost per kilowatt-hour therefor. Tenant shall pay Landlord, as Additional Rent, the .cost of its Excess Consumption within thirty (30) days of billing. The cost of the Excess Consumption shall not be charged to Operating Expenses. Landlord
shall bear the cost of making the Available Electricity available at the bus riser on each floor of the Premises. Tenant shall bear the cost of horizontally distributing the Available Electricity to the Premises, including costs related to
transformers and disconnect switches necessitated by Tenant’s Excess Consumption. 

  
 19 

 6.1.3 Landlord shall provide city water from the regular Building outlets for drinking, lavatory
and toilet purposes and shall supply chilled water, at cost to Tenant with no markup, for Tenant’s usage in connection with its supplemental HVAC units. 

6.1.4 Landlord shall provide janitorial services Monday through Friday except the date of observation of the Holidays, in and about the
Premises in accordance with the cleaning specifications attached hereto’ as Exhibit I (the “Cleaning Specifications”). Notwithstanding the foregoing, Tenant reserves the right to provide, at its own cost
and expense, its own janitorial service to any part of the Premises designated in writing to Landlord as a high-security area, as determined by Tenant (“Security Area”), provided that the janitorial service retained by Tenant shall
conduct its activities in and around the Premises in a harmonious relationship with all other subcontractors, laborers, materialmen and suppliers at the Premises, Building and Project, and, if necessary, Tenant shall employ union labor to achieve
such harmonious relations. In such case, Tenant’s Share of Operating Expenses (as it applies to janitorial services) shall be adjusted to reflect that the Security Area portion of the Premises (reflected on a per-square-foot basis) is not to be
allocated the janitorial expense portion of Operating Expenses. 
 6.1.4.1 Window Washing Equipment. Landlord shall not store or
operate window washing equipment on the balconies of the Building or along the ledges surrounding the floors of the Building containing the Premises in such a manner so as to interfere with Tenant’s use of the Premises. Landlord agrees that
during all times that such equipment is not in use, such equipment shall be concealed from view from any and all employees, invitees and guests of Tenant from any portion of the Premises. Landlord agrees that no window washing personnel shall enter
the Premises in order to access the exterior of the Building. Otherwise, Landlord agrees that the operation of such window washing equipment shall be conducted in a manner (and during times) consistent with the practices of the Comparable Buildings,
provided that the exterior windows of the Building shall be washed at least two (2) time per Lease Year. 
 6.1.5 Except as otherwise
provided in the “Passenger Elevator Specifications,” as that term is defined below, Landlord shall provide nonexclusive automatic passenger elevator service. All passenger elevators serving the Premises shall be operational during normal
business hours (subject to normal servicing) and at least one (1) (or two (2) upon Tenant’s request) passenger elevators in each elevator bank shall be operational at all other times. The passenger elevator service shall be provided
in accordance with the passenger elevator specifications attached hereto as Exhibit J (the “Passenger Elevator Specifications”). 

6.1.6 Landlord shall provide nonexclusive freight elevator service during the normal business hours, subject to reasonable and
nondiscriminatory scheduling by Landlord. Tenant shall also be entitled to non-exclusive use of the freight elevator service at all times other than normal business hours, subject to reasonable and nondiscriminatory scheduling by Landlord, and
Tenant shall be charged for such non-normal business hours usage at a rate equal to Landlord’s actual cost of providing such service, which rate shall include a labor charge but shall reflect the additional depreciation of the freight elevator
as a result of such use, provided that such rate shall not provide Landlord with any profit from Tenant’s use of the freight elevator during non-normal business hours. Charges for such service shall be deemed Additional Rent hereunder and shall
be billed on a monthly basis. Landlord shall establish adequate security measures to restrict access to the freight elevators by unauthorized personnel. Notwithstanding the foregoing, Landlord shall provide Tenant, at Landlord’s sole expense,
with priority scheduling by Landlord for freight elevator service during the construction of the tenant improvements in any First Offer Space, Expansion Space, or Hold Space and Tenant’s move-in to such space. 

6.1.7 Landlord shall provide, twenty-four (24) hours per day, seven (7) days per week, throughout the Lease Term, including the
periods of occupancy by Tenant prior to the Lease Commencement Date, security for the Building, including the Building and the On-site Parking Area, including all pedestrian and vehicular entries thereto in a manner consistent with the Comparable
Buildings with respect to, among other things, the amount of personnel, time shifts worked by such personnel, the security systems and equipment utilized by such personnel and the Building, and the security procedures used by such personnel
(“Landlord’s Security”). Tenant hereby waives all claims against Landlord arising from the provision of Landlord’s Security, except to the extent caused by the gross negligence or willful misconduct of Landlord,

  
 20 

 
its agents or employees or contractors. Landlord shall maintain Landlord’s Security in a first-class, state-of-the-art manner consistent with the security systems, equipment, personnel and
procedures maintained at the Comparable Buildings. Landlord’s Security shall provide Tenant, upon Tenant’s request and subject to availability, with an escort to the vehicles of Tenant’s employees located in the Parking Facilities
through the use of Landlord’s Security personnel. Tenant may, at its own expense, install its own security system (“Tenant’s Security”) in the Premises and common stairwells of the Building; provided, however, that Tenant
shall coordinate the installation and operation of Tenant’s Security with Landlord to assure that Tenant’s Security is compatible with Landlord’s Security. Tenant shall be solely responsible for the monitoring and operation of
Tenant’s Security system. Tenant shall have the right to refuse admission of persons to the Premises, except for Landlord’s representatives in the event of an emergency or pursuant to Landlord’s entry right set forth in this Lease.

 6.1.8 Landlord shall at all times provide capacity in the existing Building telephone riser conduit and telephone riser closets for
Tenant’s telephone and telecommunications cabling as set forth in Exhibit Q attached hereto. Tenant shall be granted access to the Building telephone closets in the Building, and Landlord shall provide Tenant a key to access such
rooms, which rooms shall otherwise be kept locked at all times. Landlord shall notify Tenant, except in case of emergency, prior to any work requiring access to any Building telephone closets on the floors of the Building containing the Premises and
shall ensure that such work is completed under the direct supervision of Landlord, or, at Tenant’s option, Landlord and Tenant. 

6.1.9 Landlord shall, as part of Operating Expenses, (i) supply and install Building standard light bulbs for the Premises, and
(ii) install non-Building standard light bulbs in the Premises (if the same are provided to Landlord by Tenant). 
 6.2 Overstandard
Tenant Use. Tenant shall not, without Landlord’s prior written consent, use heat-generating machines or equipment or lighting which (i) causes Tenant to use Excess Consumption if such Excess Consumption does affect the temperature
otherwise maintained by the air conditioning system or (ii) increases 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
install 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, including the removal thereof upon the expiration or earlier termination of the Lease Term, shall be paid by Tenant to Landlord within thirty (30) days after Tenant’s receipt of invoice. If
Tenant uses water in excess of that supplied by Landlord pursuant to Section 6.1 of this Lease, Tenant shall pay to Landlord, upon billing, the Actual Cost of such excess consumption, and the Actual Cost of the installation, operation, and
maintenance of equipment which is installed in order to supply such excess consumption. 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 (“After Hours HVAC”), Tenant shall give Landlord notice by 3:00 p.m. on weekdays for same day usage and 5:00 p.m. on Fridays for weekend usage of Tenant’s desired use and Landlord
shall supply such utilities to Tenant at Landlord’s Actual Cost. Amounts payable by Tenant to Landlord for such use of additional utilities shall be deemed Additional Rent hereunder and shall be billed on a monthly basis. 

6.3 Interruption of Use. Tenant agrees that, except as otherwise provided in this Lease, including Section 6.3.1, below, Landlord
shall not be liable for damages, by abatement of Rent or otherwise, for failure to furnish or delay in furnishing any service, 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 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 after reasonable effort to do so, by any 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. Furthermore, Landlord shall not be liable under any circumstances for 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. 

  
 21 

 6.3.1 Notwithstanding anything to the contrary contained in this Lease, if Tenant is prevented
from using the Premises or any portion thereof (the “Affected Area”) to conduct its normal business operations and Tenant cannot, in fact, use the Affected Area for a period of three (3) consecutive business days or more,
(i) due to any service (including but not limited to passenger elevator service, janitorial service, HVAC, (excluding the portion of such designed and constructed by Tenant) electricity or water) (collectively, the “Essential
Services”) not being provided to the Affected Area as required by the terms of this Lease, (ii) because of the presence, in a form or concentration in violation of applicable law then in effect, of Hazardous Materials regarded as
unhealthful under applicable regulations then in effect in or about the Premises (which Hazardous Materials were not brought onto the Premises by Tenant or Tenant’s employees, agents, or licensees), or (iii) due to Force Majeure (other
than as a result of fire or other casualty, which is separately addressed in Article 11 of this Lease), the following shall apply (any such set of circumstances as set forth in items (i) through (iii), above, to be known as an
“Abatement Event”). Tenant shall promptly deliver to Landlord notice (the “Cure Notice”) of such condition and if Landlord fails to cure such condition within two (2) business days after delivery to it of the
Cure Notice, then Rent applicable to the Affected Area (and to the extent parking passes rented by Tenant pursuant to this Lease correspond to the Affected Area and are not used by Tenant, then fees for such applicable parking passes) shall be
abated from the date which occurred three (3) fun business days prior to delivery to Landlord of the Cure Notice until the date when such failure is cured; provided, however, that if Tenant has previously paid Rent, including parking fees to
Landlord for a period of time subsequent to the commencement of Tenant’s right to abate Rent hereunder, then Landlord shall, within ten (10) business days following the date of such abatement, credit to Tenant the amount of such excess
payments against the sums next due under this Lease; provided, however, that if Landlord has not cured such Abatement Event within twelve (12) months after receipt of the Cure Notice (or, in the event that the Premises or the Building are
rendered inaccessible to Tenant by a casualty or act of Landlord, twelve (12) months following the date of Landlord’s actual knowledge of the occurrence of the Abatement Event) (which applicable twelve (12) month period shall not be
extended in excess of six (6) months as a result of any event of Force Majeure), Tenant shall have the right to terminate this Lease during the first five (5) business days of each calendar month following the end of such twelve
(12) month period until such time as Landlord has cured the Abatement Event, which right may be exercised only by delivery of notice to Landlord (the “Abatement Event Termination Notice”) during such five (5) business-day
period, and shall be effective as of a date set forth in the Abatement Event Termination Notice (the “Abatement Event Termination Date”), which Abatement Event Termination Date shall not be earlier than the end of the month. Tenant
may at any time prior to any Abatement Event Termination Date void any previously delivered Abatement Event Termination Notice. Notwithstanding the foregoing, if Tenant delivers a Abatement Event Termination Notice to Landlord, then Landlord shall
have the right to suspend the occurrence of the Abatement Event Termination Date for a period ending thirty (30) days after the Abatement Event Termination Date set forth in the Abatement Event Termination Notice by delivering to Tenant, within
five (5) business days of Landlord’s receipt of the Abatement Event Termination Notice, a certificate of Landlord’s contractor responsible for the repair of the Abatement Event certifying that it is such contractor’s good faith
judgment that the repairs shall be substantially completed within thirty (30) days after the Abatement Event Termination Date. If repairs shall be substantially completed prior to the expiration of such thirty-day period, then the Abatement
Event 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. Tenant shall have no
rights at law or in equity to terminate this Lease, except as expressly set forth in this Lease, including this Section 6.3.1. 
 6.3.2 If
any governmental entity promulgates or revises any statute, ordinance, building code, fire code or other code or imposes mandatory controls on Landlord or the Real Property or any part thereof, relating to the use or conservation of energy, water,
gas, light or electricity or the reduction of automobile or other emissions or the provision of any other utility or service provided with respect to this Lease or if Landlord is required to make alterations to the Building or any other part of the
Real Property in order to comply with such mandatory or voluntary controls or guidelines, then Landlord shall comply with such mandatory controls or make such alterations to the Building or any other part of the Real Property related thereto without
creating any liability of Landlord to Tenant under this Lease, provided that the Premises are not thereby rendered untenantable. Such compliance and the making of such permitted alterations shall, except as provided in Section 6.3.1, not
entitle Tenant to any damages, relieve 

  
 22 

 
Tenant of the obligation to pay the fun Rent reserved hereunder or constitute or be construed as a constructive or other eviction of Tenant. 

6.4 Additional Services. Landlord shall also have the non-exclusive right, but not the obligation, to provide any additional services
which may be required by Tenant, including, without limitation, locksmithing, lamp replacement, additional janitorial service, and additional repairs and maintenance, provided that Tenant shall pay to Landlord upon billing, Landlord’s Actual
Costs of such additional services. 
 6.5 Actual Cost. When Tenant is required to pay Landlord for any service or utility, Tenant
shall pay Landlord’s “Actual Cost.” “Actual Cost” shall be the actual costs paid or incurred by Landlord (including reasonable administrative costs to cover actual labor costs, which are not part of Operating
Expenses), unless such actual costs paid or incurred cannot be readily ascertained, in which event “Actual Cost” shall be the amount reasonably estimated by Landlord. Upon written request by Tenant from time to time, Landlord shall, within
ten (10) business days thereafter, disclose to Tenant in writing the basis for any such estimate. In the event that such disclosure demonstrates that Landlord’s estimate of its Actual Cost was unreasonably calculated, then Actual Cost
shall be appropriately adjusted. In the case of any increase resulting from such adjustment, Tenant shall pay Landlord the difference within ten (10) days of Landlord’s demand therefor. In the case of a decrease, Landlord shall credit to
Tenant the difference against the next due amount of Operating Expenses. In the event that more than one tenant orders any extra service or utility, if any cost item is applicable to more than one tenant, such cost shall be apportioned among such
tenants in accordance with the ratios of the square footages of their respective premises. Such Actual Cost, to the extent reimbursed to Landlord by Tenant and/or other tenants, shall be netted out of Operating Expenses to the extent previously
charged to Operating Expenses or to the extent that the work was performed by individuals whose salaries or charge for services are included in Operating Expenses. 

6.6 No Preferential Treatment to Other Tenants. Landlord shall not offer any other tenants of the Building preferential economic
treatment with respect to After-Hours HVAC or other non-standard services or utilities provided to Tenant pursuant to this Lease, including this Article 6. 

ARTICLE 7 

REPAIRS 
 7.1
Operation of Building: Compliance with Law. 
 7.1.1 General. Landlord shall, as part of Operating Expenses to the extent
permitted under Article 4 of this Lease, operate, improve, lease, manage and maintain the Building, Base Building, Common Areas, and the On-site Parking Area in accordance with all governmental laws, rules and regulations in a manner consistent with
Class “A” buildings located in the vicinity of the Building. 
 7.1.2 Landlord Repair. Landlord shall keep and maintain the
Common Area, the Building’s exterior walls, glass, roof and foundation, the Base Building, the “Building Systems,” as that term is defined in Section 7.2.3, below, located outside the Premises, and the Building Systems that are
located in the Premises in proper working order, condition and repair, except to the extent such repairs are caused by the negligence or wilful misconduct of Tenant, or its invitees, employees, agents or contractors and such repairs are not covered
by insurance (deductibles are not deemed to be covered by insurance) required to be carried by Landlord under this Lease. 
 7.1.3
Compliance with Law by Landlord and Tenant. Landlord shall keep and maintain the Building, Base Building, the Building Systems located outside the Premises and the Building Systems located in the Premises, in compliance with any law, statute,
ordinance or other governmental rule, regulation or requirement now in force or which may hereafter be enacted or promulgated, including any standard or regulation now or hereafter imposed on Landlord 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, that relates to Tenant’s use or occupancy of the Premises or the operation of the Building
(collectively, “Legal Requirements”); provided, however, that Tenant hereby 

  
 23 

 
covenants and agrees that if such compliance is required in the Premises or the Building, and (i) such compliance relates to the Tenant Improvements or Alterations, or (ii) such
compliance is required as a result of Tenant’s non-general office use of the Premises, Tenant shall be responsible for the cost of causing, and Tenant shall cause, the Tenant Improvements, the Alterations, the Base Building or the Building
Systems and Equipment located outside the Premises and on the floor(s) on which the Premises are located (but then only to the extent that the cost of such compliance is not included in Operating Expenses), as the case may be, to comply with such
requirements. 
 7.2 Tenant Maintenance and Repair. 

7.2.1 If Tenant provides notice (the “Repair Notice”) to Landlord of an event or circumstance (i) which constitutes a
failure by Landlord in the performance of its obligations pursuant to Section 6.1, above, except with respect to elevators and window washing equipment; or (ii) which constitutes a failure by Landlord in the performance of its obligations
under Article 7 of this Lease, and the failure to fulfill such obligation will (a) materially interfere with Tenant’s access to the Project, Building or Premises, (b) materially interfere with the provision by Landlord of services and
utilities to the Premises as required by Section 6.1 of this Lease, (c) materially interfere with Tenant’s business operation in the Premises, or (d) cause Tenant not to have the legal right to occupy the Premises; or
(iii) which constitutes a failure by Landlord in the performance of its obligations under this Lease which relates to an “Emergency,” as that term is defined in Section 7.2.2, below (a “Required Action”), and Landlord
fails to provide the Required Action within the time period required by this Lease, or a reasonable period of time, if no specific time period is specified in this Lease, after the receipt of the Repair Notice (the “Notice Date”),
or, in any event, does not commence the Required Action within ten (10) days after the Notice Date and complete the Required Action within thirty (30) days after the Notice Date (provided that if the nature of the Required Action is such
that the same cannot reasonably be completed within a thirty (30) day period, Landlord’s time period for completion shall not be deemed to have expired if Landlord diligently commences such cure within such period and thereafter diligently
proceeds to rectify and complete the Required Action, as soon as possible), then Tenant may proceed to take the Required Action, pursuant to the terms of this Lease, and shall deliver a second notice to Landlord specifying that Tenant is taking the
Required Action (the “Second Notice”). 
 7.2.2 Notwithstanding the foregoing, if there exists an emergency (an
“Emergency”) such that the Premises or a portion thereof are rendered in such a state so as to create an imminent threat to health or human safety and if Tenant gives the Building’s management office notice (the
“Emergency Notice”) of Tenant’s intention to take action with respect thereto (the “Necessary Action”) and the Necessary Action is also a Required Action, Tenant may take the Necessary Action if Landlord does
not commence the Necessary Action within one (1) business day after the Emergency Notice (the “Emergency Cure Period”) and thereafter use its best efforts and due diligence to complete the Necessary Action as soon as possible.

 7.2.3 If any Necessary Action will affect the systems and equipment located within the Building (the “Building
Systems”), the structural integrity of the Building, or the exterior appearance of the Building, Tenant shall use only those contractors used by Landlord in the Building for work on the Building Systems, or its structure, and Landlord shall
provide Tenant (when available and upon Tenant’s request) with notice identifying such contractors and any changes to the list of such contractors, unless such contractors are unwilling or unable to perform such work or the cost of such work is
not competitive, in which event Tenant may utilize the services of any other qualified contractors which normally and regularly performs similar work in the Comparable Buildings except for any contractors who Landlord specifically notifies Tenant in
writing within five (5) business days of Landlord’s receipt of a Repair Notice or within one (1) business day of Landlord’s receipt of an Emergency Notice that Tenant may not use for such work (which notice shall specify the
commercially reasonable reasons for Landlord’s not allowing Tenant to use such contractor.) 
 7.2.4 If any Required Action or
Necessary Action is taken by Tenant pursuant to the terms of this Section 7.2, then Landlord shall reimburse Tenant for its reasonable, actual and documented costs and expenses in taking the Required Action or Necessary Action within thirty
(30) days after receipt by Landlord of an invoice from Tenant which sets forth a reasonably particularized breakdown of its costs and expenses in connection with taking the Required 

  
 24 

 
Action or Necessary Action on behalf of Landlord (the “Repair Invoice”). Notwithstanding the foregoing, if Landlord delivers to Tenant within thirty (30) days after receipt
of the Repair Invoice, a written objection to the payment of such invoice, setting forth with reasonable particularity Landlord’s reason for its claim that the Required Action or Necessary Action did not have to be taken by Landlord pursuant to
the terms of this Lease or that Tenant breached the terms of this Section 7.2, or that the charges are excessive (in which case Landlord shall pay the amount it contends would not have been excessive), then the dispute shall be submitted to
arbitration in accordance with the terms of Article 24 of this Lease for resolution. In the event Landlord does not timely object as set forth above, and Landlord does not reimburse Tenant for the Repair Invoice within thirty (30) days of
receipt, then Tenant may deduct from the next Rent payable by Tenant under this Lease, the amount set forth in the Repair Invoice plus interest at the Interest Rate. 

7.3 Tenant Repair. Except as set forth in Section 7.1 as Landlord’s obligations, and in addition to the obligations of Tenant
set forth in Section 7.1, above, Tenant shall, at Tenant’s own expense, keep all other portions of the Premises, including all Tenant Improvements, all telephone and telecommunications cabling systems utilized by Tenant
(“Telecommunication Systems”), fixtures and furnishings therein, in good order, repair and condition at all times during the Lease Term and Tenant shall promptly notify Landlord of any damage to the Premises from any cause. 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
for which it is responsible; provided however, that, at Landlord’s option, if Tenant fails to make such repairs, Landlord may, but need not, upon reasonable advance notice to Tenant, make such repairs and replacements, and Tenant shall pay to
Landlord, Landlord’s Actual Cost thereof plus interest at the Interest Rate within thirty (30) days after being billed for same. Tenant hereby waives and releases any right it may have to make repairs at Landlord’s expense under
Sections 1941 and 1942 of the California Civil Code or under any similar law, statute, ordinance or common law now or hereafter in effect. 

ARTICLE 8  

ADDITIONS AND ALTERATIONS 

8.1 Landlord’s Consent to Alterations. Except for the “Tenant Improvements,” as that term is defined in
Section 2.1 of the Tenant Work Letter, which shall be governed by the terms of the Tenant Work Letter, Tenant may not make any improvements, alterations, additions or changes to the Premises (collectively, the
“Alterations”) without first procuring the prior written consent of Landlord to such Alterations, which consent shall not be unreasonably withheld, conditioned or delayed by Landlord and shall be approved or denied by notice
received by Tenant within ten (10) business days of Landlord’s receipt of request for consent and shall be deemed disapproved, if such notice of consent or denial is not received by Tenant within such ten (10) business day period;
provided, however, the parties hereby agree that it shall be reasonable under this Lease for Landlord to withhold consent to any proposed Alteration only where such Alteration alters the Building’s exterior appearance, or has a material adverse
effect on the Building Systems and equipment or the Building structure (collectively, “Adverse Effects”). Notwithstanding the foregoing, Tenant may (i) make Alterations to the Premises which do not cause Adverse Effects without
Landlord’s consent, provided that Tenant shall give Landlord at least five (5) business days prior notice of the same, or (ii) replace the floor and wall coverings and the furniture, fixtures and equipment in the Premises without
prior notice to Landlord so long as such Alterations do not cause Adverse Effects. The construction of the initial improvements to the Premises shall be governed by the terms of the Tenant Work Letter and not the terms of this Article 8. 

8.2 Plans/Contractors. Prior to commencing any Alterations which require Landlord’s consent under this Article 8, Tenant must
submit to Landlord for Landlord’s reasonable approval detailed plans and specifications for such work. Landlord’s approval or disapproval shall be delivered to Tenant within ten (10) business days following Tenant’s delivery to
Landlord of such plans and specifications; and if Landlord disapproves such plans and specifications, Landlord shall state the reasons for its disapproval. Any material changes in, deviations from, modifications of, or amendments to any plans and
specifications approved by Landlord shall also require Landlord’s prior approval Landlord’s review and approval of any plans and specifications (and any material modifications thereto) shall not create any

  
 25 

 
responsibility or liability on the part of Landlord for their completeness, design sufficiency, or compliance with applicable Laws. Prior to commencing any Alterations which require
Landlord’s consent, Tenant must obtain Landlord’s reasonable approval of Tenant’s proposed general contractor, if any, and any mechanical, electrical, plumbing and fire protection trade contractors; and Tenant specifically
acknowledges that it shall not be unreasonable for Landlord to withhold approval of any proposed contractor on the grounds that Landlord reasonably believes that the performance of work in the Building by such contractor or any of its subcontractors
could invalidate any warranty or guaranty covering any Building System or component thereof or could result in labor disputes with Landlord’s own contractors or employees of Landlord or Landlord’s contractors. 

8.3 Manner of Construction. Landlord may impose, as a condition of its consent to 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 perform any work which in Landlord’s judgment is likely to disturb other tenants of the
Building only during non-business hours. Tenant shall construct such Alterations and perform such repairs in conformance with any and all applicable rules and regulations of any federal, state, county or municipal code or ordinance and pursuant to a
valid building permit, issued by the City of San Francisco, in conformance with Landlord’s reasonable and non-discriminatory construction rules and regulations. All work with respect to any Alterations must be done in a good and workmanlike
manner and diligently prosecuted to completion to the end that the Premises shall at all times be a complete unit except during the period of work. In performing the work of any such Alterations, Tenant shall have the work performed in such manner
as not to obstruct access to the Building or the common areas for any other tenant of the Building. 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 Tenant shall deliver to the Building management office a reproducible copy of the “as built” drawings of the
Alterations; provided, however, that if Tenant does not cause a timely Notice of Completion to be recorded, such failure shall not constitute a default under this Lease but Tenant shall protect, defend, indemnify and hold Landlord harmless from any
loss, cost, damage, claim or expense incurred by Landlord in connection with Tenant’s failure to record the Notice of Completion. 

8.4 Payment for Improvements. Upon completion of such work not ordered from Landlord, Tenant shall deliver to Landlord, if payment is
made directly to contractors, evidence of payment, contractors’ affidavits and fun and final waivers of all liens for labor, services or materials. 

8.5 Construction Insurance. In the event that Tenant makes any Alterations, Tenant agrees to carry “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. 
 8.6 Landlord’s Property. All Alterations,
improvements, fixtures and/or equipment which may be installed or placed in or about the Premises or the Real Property, and all signs installed in, on or about the Premises or the Real Property, from time to time, shall be at the sole cost of Ten
ant and shall be and become the property of Landlord, except that Tenant may remove (i) any trade fixtures and/or equipment and (ii) the “Wall Partition System” within the Premises (collectively, “Tenant’s
Property”) and Tenant may also remove any “Personal Property,” as that term is defined in Section 15.1, provided, in each instance, Tenant repairs any damage to the Premises and Building caused by such removal. Tenant shall
have no obligation to remove any Alteration upon the expiration or early termination of the Lease Term, but Tenant shall broom clean the Premises concurrently with Tenant’s vacation thereof. If Tenant fails to repair any damage caused by the
removal of any of Tenant’s Property or Personal Property, Landlord may do so and may charge the cost thereof to Tenant. Tenant shall have the right, but not the obligation, to finance the purchase of and grant security interests in and
otherwise encumber Tenant’s Personal Property, and Landlord shall, promptly upon request, execute a waiver and consent form required by any lender of Tenant granting such lender the right, upon reasonable notice, to enter the Premises to take
possession of and remove Tenant’s Personal Property notwithstanding any alleged breach by Tenant of the terms of this Lease. Tenant hereby 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 

  
 26 

 
such Alterations, improvements, fixtures and/or equipment in, on or about the Premises, except damages caused by the negligence, willful misconduct or breach of this Lease by Landlord, its
employees, agents, and contractors, or covered by Landlord’s insurance carried as required under this Lease or if Landlord fails to carry such coverage, which would have been covered by Landlord’s insurance required to be carried under
this Lease. 
 ARTICLE 9 

COVENANT AGAINST LIENS 

Tenant has no authority or power to cause or permit any lien or encumbrance of any kind whatsoever, whether created by act of Tenant,
operation of law or otherwise, to attach to or be placed upon the Real Property, Building or Premises, and any and all liens and encumbrances created by Tenant shall attach to Tenant’s interest only. Landlord shall have the right at all times
to post and keep posted on the Premises any notice which it deems necessary for protection from such liens. Tenant covenants and agrees not to suffer or permit any lien of mechanics or materialmen or others to be placed against the Real Property,
the Building or the Premises with respect to work or services claimed to have been performed for or materials claimed to have been furnished to Tenant or the Premises, and, in case of any such lien attaching or notice of any lien, Tenant covenants
and agrees to cause it to be released and removed of record within thirty (30) days after Tenant’s receipt of notice from Landlord regarding the existence of such lien. Notwithstanding anything to the contrary set forth in this Lease, in
the event that such lien is not released and removed on or before the date occurring thirty (30) days after notice of such lien is delivered by Landlord to Tenant, Landlord, at its sole option, upon an additional notice to Tenant, may take all
reasonable action necessary to release and remove such lien, without any duty to investigate the validity thereof, and all reasonable sums, costs and expenses, including reasonable attorneys’ fees and costs, incurred by Landlord in connection
with such lien shall be deemed Additional Rent under this Lease and shall be due and payable by Tenant within thirty (30) days after Tenant’s receipt of an invoice therefor. 

ARTICLE 10 

INSURANCE 
 10.1
Indemnification and Waiver. To the extent not prohibited by law, and except as caused by the negligence or wilful misconduct of Landlord, its agents and employees, Landlord, its partners and their respective officers, agents, servants,
employees, and independent contractors shall not be liable for, and Tenant hereby waives any claim against Landlord and such other persons for, any damage 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, due to the Building or any part thereof or any appurtenances thereof becoming out of repair (including any improvements, materials, or equipment relating to telephone or telecommunication systems),
or due to the occurrence of any accident or event in or about the Building or due to any act or neglect of any tenant or occupant of the Building, including the Premises, or of any other person, and Tenant, as a material part of the consideration to

electricity, steam, sewage, sewer gas or odors, fire, water or by the bursting or leaking of pipes, faucets, sprinklers, plumbing fixtures and windows, and shall apply without distinction as to the person whose act or negligence was responsible for
the damage and whether the damage was due to any of the causes specifically enumerated above or to some other cause of an entirely different nature. Tenant further agrees that all personal property upon the Premises, or upon loading docks, receiving
and holding areas, or freight elevators of the Building, shall be at the risk of Tenant only, and that Landlord shall not be liable for any loss or damage thereto or theft thereof. To the extent not prohibited by law, and, subject to
Section 10.6, below, Tenant shall indemnify, defend, protect, and hold harmless Landlord, its partners and their respective officers, agents, servants, employees, and independent contractors from and against 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 any cause in, on or about the Premises, including, without limiting the generality of the foregoing:
(i) any default by Tenant in the observance or performance of any of the terms, covenants or conditions of this Lease on Tenant’s part to be observed or performed; (ii) the use or occupancy of the Premises by Tenant or any person
claiming by, through or under Tenant; 

  
 27

through or under Tenant, or of the contractors, agents, servants, employees, visitors or licensees of Ten ant or any such person, in the Premises or the Real Property, including, without limitation, any acts, omissions or negligence in the making or
performance of any alterations, provided that the terms of the foregoing indemnity shall not apply to the negligence or willful misconduct of Landlord or its agents, contractors, employees or licensees (except for damage to the Tenant Improvements
and Tenant’s personal property, trade fixtures, furniture and equipment in the Premises, to the extent Tenant is required to obtain the requisite insurance coverage pursuant to this Lease). 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. Subject to Section 10.6, below, Landlord shall indemnify, defend, protect, and hold harmless Tenant and its parent, subsidiary and affiliated companies, including but not limited to
their respective directors, officers, agents, servants, employees and independent contractors (collectively, the “Tenant’s Group”), 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 or caused by any of the following occurrences or circumstances: (i) any occurrence in, on, or about the Premises if such injury or damage is caused by
the negligence or willful misconduct of Landlord; or (ii) any occurrence in, on, or about any portion of the Building not within the Premises to the extent such injury or damage shall be caused by the negligence or willful misconduct of
Landlord. The terms of the foregoing indemnity shall not apply to the negligence or willful misconduct of Tenant. The provisions of this Section 10.1 shall survive the expiration or sooner termination of this Lease with respect to any claims or
liability occurring prior to such expiration or termination. 
 10.2 Landlord’s Insurance. From and after the date hereof and
throughout the Lease Term, Landlord shall maintain in full force and effect the policies of insurance set forth below in Sections 10.2.1 through 10.2.3. 

10.2.1 Landlord’s Fire and Casualty Insurance. Property damage insurance covering the Building, the On-Site Parking Area, and the
Tenant Improvements and the Alterations (but excluding the value of the Tenant Improvements to the extent such value exceeds the value of the Building standard improvements and excluding Tenant’s “Personal Property,” as that term is
defined in Section 15.1, below), and all other improvements in and about the Common Areas in which Landlord may have an insurable interest, providing protection against any peril included within the classification “All Risk” inclusive
of standard fire and extended coverage insurance, including endorsements against vandalism, malicious mischief and’ other perils, but excluding, except as set forth below in Section 10.2.3, all in amounts not less than one hundred
percent (100%) of their fun 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 (which endorsement may, notwithstanding the foregoing provisions of this
Section 10.2.1, contain a commercially reasonable sublimit) that covers “costs of demolition,” “increased costs of construction” due to changes in building 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, the On-Site Parking Area, the Tenant Improvements, the Alterations and the Common Areas. Such policy shall also contain a “stipulated value” endorsement deleting any co-insurance provisions. In addition, Landlord
shall maintain “boiler machinery” coverage (and a joint loss agreement if the boiler machinery coverage is issued by a different insurance company than the basic property insurance). 

10.2.2 General Liability Insurance. Comprehensive general liability insurance for bodily injury and property damage, adequate to
protect Landlord and all additional insureds against liability for (i) the actions of Landlord and Landlord’s agents, employees and contractors and (ii) injury to or death of anyone or more persons in an occurrence, and for damage to
property, arising in connection with the (a) construction or alteration of the Building, the On-Site Parking Area and all improvements in and about the Common Areas, (b) the use, operation or condition of the Common Areas, or (c) the
condition of the Premises unrelated to Tenant’s use. Such insurance shall be in an amount of not less than Ten Million Dollars ($10,000,000.00) 

  
 28 

 
Combined Single Limit, which amount shall be increased throughout the Lease Term to the extent of such coverage customarily carried by landlords of Comparable Buildings, and which shall insure
against any and an liability of the insured as aforesaid. 
 10.2.3 Earthquake Coverage. Landlord hereby represents that the holder
of the first deed of trust on the Building, Citicorp Real Estate, Inc. (“CRE”) is requiring Landlord to obtain a policy of insurance covering the risk of earthquake damage to the Building (“CRE’s Requirement”).
Accordingly, Landlord will, to the extent available, obtain and maintain in full force and effect a policy of insurance covering earthquake damage to the Building (the “Earthquake Policy”). Notwithstanding anything to the contrary
set forth in this Section 10.2.3, Tenant shall only be responsible to pay Tenant’s Earthquake Insurance Contribution if (i) CRE or any subsequent holder of a first deed of trust on the Building (the “Subsequent
Lender”) requires Landlord to carry the Earthquake Policy, and Tenant receives written evidence from CRE or any Subsequent Lender regarding CRE’s Requirement or the requirement of a Subsequent Lender, respectively, and (ii) Tenant
receives a copy of the Earthquake Policy and the invoice for the premium for the Earthquake Policy. 
 10.2.4 Other Terms. Upon
inquiry by Tenant, from time to time, Landlord shall inform Tenant of such coverage carried by Landlord. The minimum limits of policies of insurance required of Landlord under the Lease shall limit the liability of Landlord under this Lease with
respect to claims covered by such insurance. The insurance obtained by Landlord pursuant to this Section 10.2 shall: (i) specifically cover the indemnification liability of Landlord under Section 10.1 of this Lease;
(ii) be issued by an insurance company having a rating of not less than A-X in Best’s Insurance Guide (the “Best’s Rating”) or which is otherwise reasonably acceptable to Tenant and licensed to do business in the
State of California; (iii) primary insurance (A) with respect to the insurance described in Section 10.2.1 and 10.2.3, above, as to all claims thereunder and (B) with respect to insurance described in
Section 10.2.2, above, as to claims arising outside the Premises, and in either event, such insurance shall provide that any insurance carried by Tenant is excess and is non-contributing with any such insurance requirement of Landlord; and
(iv) provide that said insurance shall not be canceled or coverage materially reduced unless thirty (30) days’ prior written notice shall have been given to Tenant. With respect to the insurance described in Sections 10.2.2 and
10.2.3, Tenant shall be named as an additional insured as its interests may appear. Tenant shall neither use the Premises nor permit the Premises to be used or acts to be done therein which will (a) increase the premium of any insurance
described in this Section 10.2; (b) cause a cancellation of or be in conflict with any such insurance policies; or (c) result in a refusal by insurance companies of good standing to insure the Building in amounts reasonably
satisfactory to Landlord, provided, however, that Tenant shall at all times be permitted to use the Premises for the uses permitted by Article 5 of this Lease without being required to pay additional insurance premiums. Tenant shall, at
Tenant’s expense, comply with all 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 and such conduct or use is
not permitted by the terms of this Lease, then Tenant shall reimburse Landlord for any such Increase. 
 10.3 Tenant’s
Insurance. Tenant shall maintain Comprehensive General Liability Insurance covering the insured against claims of bodily injury, personal injury and property damage arising out of Tenant’s operations, assumed liabilities or use of the
Premises, including a Broad Form Comprehensive General Liability endorsement covering the insuring provisions of this Lease and the performance by Tenant of the indemnity agreements set forth in Section 10.1 of this Lease, for limits of
liability not less than: 
  

			
	 Bodily Injury and

Property Damage Liability
	  	$5,000,000 each occurrence
		  	$5,000,000 annual aggregate
		
	 Personal Injury Liability
	  	 $5,000,000 each occurrence
 $5,000,000 annual
aggregate

	 0% Insured’s participation
	  	

 10.4 Form of Policies. The minimum limits of policies of insurance required of Tenant under this Lease
shall in no event limit the liability of Tenant under this Lease. Such insurance 

  
 29 

 
shall (i) name Landlord, Landlord’s property manager, Landlord’s lender, and the ground lessor as an additional insured; (ii) specifically cover the liability assumed by
Tenant under this Lease, including, but not limited to, Tenant’s obligations under Section 10.1 of this Lease; (iii) be issued by an insurance company having a rating of not less than A-X in Best’s Insurance Guide or which is
otherwise reasonably acceptable to Landlord and licensed to do business in the State of California; (iv) be primary insurance as to all claims thereunder arising within the Premises and provide that any insurance carried by Landlord with
respect to claims arising within the Premises is excess and is non-contributing with any insurance requirement of Tenant; (v) provide that said insurance shall not be canceled or coverage changed unless thirty (30) days’ prior written
notice shall have been given to Landlord and any mortgagee of Landlord whose names and addresses have been provided by Landlord together with a specific reference to this requirement; and (vi) contain a cross-liability endorsement or
severability of interest clause reasonably acceptable to Landlord. Tenant shall deliver said policy or policies or certificates thereof to Landlord on or before the Lease Commencement Date and at least thirty (30) days before the expiration
dates thereof. 
 10.5 Self-Insurance. The Tenant named in the Summary shall be entitled to self-insure its insurance requirements
set forth in Sections 10.3 and 8.5 of this Lease, and Section 6.12 of the Tenant Work Letter. Any self-insurance shall be deemed to contain all of the terms and conditions applicable to such insurance as requited in this
Article 10, including, without limitation, a full waiver of subrogation. If Tenant elects to so self-insure, then with respect to any claims which may result from incidents occurring during the Lease Term, such self-insurance obligation shall
survive the expiration or earlier termination of this Lease to the same extent as the insurance required would survive. Notwithstanding the foregoing, Tenant shall only have the right to self-insure its insurance requirements under Section 10.3
of this Lease, if Tenant shall, concurrent with a notice to Landlord electing to self-insure, provide Landlord with evidence that Tenant has a net worth of equal to or greater than Three Hundred Million Dollars ($300,000,000.00) (the
“Financial Requirement”). If Tenant at any time does not satisfy the Financial Requirement, it shall notify Landlord of the same and supply Landlord with the insurance policies required under Section 10.3 of this Lease. 

10.6 Subrogation. Landlord and Tenant agree to have their respective insurance companies issuing property damage insurance waive any
rights of subrogation that such companies may have against Landlord or Tenant, as the case may be, so long as the insurance carried by Landlord and Tenant, respectively, is not invalidated thereby. As long as such waivers of subrogation do not
invalidate such insurance, Landlord and Tenant hereby waive any right that either may have against the other on account of any loss or damage to their respective property to the extent such loss or damage is insurable under policies of insurance for
fire and all risk coverage, theft, public liability, or other similar insurance. If either party fails to carry the amounts and types of insurance required to be carried by it pursuant to this Article 10, such failure shall be deemed to be a
covenant and agreement by such party to self-insure with respect to the type and amount of insurance which such party so failed to carry, with full waiver of subrogation with respect thereto. 

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 (“Premises
Damage”) resulting from fire or any other casualty. If the Premises or the Real Property 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 Real Property, the Premises, and such common areas (the “Restoration”). The Restoration shall be to substantially
the same condition of the Real Property, the Premises, and common areas prior to the casualty, except for modifications required by zoning and building codes and other laws, provided access to the Premises and any common restrooms serving the
Premises shall not be materially impaired. Upon the occurrence of any damage to the Premises, of Real Property Landlord shall repair any injury or damage to the Tenant Improvements and Alterations or Real Property and shall return such Tenant
Improvements and Alterations or Real Property to their original condition. In connection with such repairs and replacements, Tenant shall, prior to the commencement of construction, submit to Landlord, for Landlord’s review and approval, all
plans, specifications and working drawings relating to the 

  
 30 

 
Tenant Improvements and Alterations, and Tenant 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, Landlord shall allow Tenant a proportionate abatement of Rent during the time and to the extent the Premises are unfit for occupancy for the purposes permitted under this Lease, and not occupied by Tenant as a result thereof; provided,
however, that if the Premises is damaged such that the remaining portion thereof is not sufficient to allow Tenant to conduct is business operations from such remaining portion and Tenant does not conduct its business operations therefrom, Landlord
shall allow Tenant a total abatement of Rent during the time and to the extent the Premises are unfit for occupancy for the purposes permitted under this Lease, and not occupied by Tenant as a result of the subject damage. All insurance proceeds
from the policies as described in Sections 10.2.1 and 10.2.3 shall be assigned by Landlord and Tenant to be used in connection with the repair of damage to the Premises and Real Property. Notwithstanding anything to the contrary set forth in this
Section 11.1, to the extent Landlord does not commence Restoration within sixty (60) days of the date of damage, Tenant shall deliver notice (the “Restoration Failure Notice”) to Landlord of Landlord’s failure to
commence Restoration, and provided that Landlord has not exercised the Reimbursement Right pursuant to Section 3.4, above, Tenant may elect to pursue any remedies available to Tenant at law or in equity including, but not limited to, an
action against Landlord for specific performance with respect to the Restoration, which remedy of specific performance Landlord and Tenant hereby agree shall be available to Tenant. 

11.2 Tenant’s Termination Right. If the repairs cannot be completed within twelve (12) months after the date of damage (which
twelve (12) month period shall not be extended in excess of six (6) months as a result of any event of “Force Majeure,” as that term is defined in Section 29.17, below), Tenant may elect, no earlier than sixty (60) days
after the date of the damage and not later than the 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 Landlord has advised Tenant that repairs can be completed within a twelve (12) month period, and Tenant has not terminated this
Lease, and the repairs are not actually completed within such twelve (12) months’ period (which twelve (12) month period shall not be extended in excess of six (6) months as a result of any event of Force Majeure), Tenant shall
have the right to terminate this Lease during the first five (5) business days of each calendar month following the end of such period 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 earlier than the end of each such month. Tenant may at any time prior
to any Damage Termination Date void any previously delivered 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. If Tenant terminates this Lease pursuant to the terms of this
Section 11.2, Tenant shall receive, and Landlord shall assign to Tenant, insurance proceeds equal to the Unamortized Value as of the Tenant Termination Date of the Tenant Costs (as calculated pursuant to Section 3.4.2 above), provided that
Landlord has not exercised the Reimbursement Right pursuant to Section 3.4, above. 
 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 and all damage to, or destruction of, all or any part of the Premises, the Building or any other

  
 31 

 
portion of the Real Property, 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 any other portion of the Real Property. 
 11.4 Damage Near End of
Term. In the event that the Premises or the Building is destroyed or damaged to any substantial extent during the last twenty-four (24) months of the Lease Term, then notwithstanding anything contained in this Article 11, Tenant shall have
the option to terminate this Lease by giving written notice to Landlord of the exercise of such option within sixty (60) days after such damage or destruction, in which event this Lease shall cease and terminate as of the date of such notice,
Tenant shall pay the Base Rent and Additional Rent, properly apportioned up to such date of damage, and both parties hereto shall thereafter be freed and discharged of all further obligations hereunder, except as provided for in provisions of this
Lease which by their terms survive the expiration or earlier termination of the Lease Term. 
 ARTICLE 12  

NONWAIVER 
 No
waiver of any provision of this Lease shall be implied by (i) any failure of either party to insist in any instance on the strict keeping, observance or performance of any covenant or agreement contained in this Lease or to exercise any
election contained in this Lease or (ii) any failure of either party to enforce any remedy on account of the violation of such provision, even if such violation shall continue or be repeated subsequently. Any waiver by either party of any
provision of this Lease may only be in writing, and no express waiver shall affect any provision other than the one specified in such waiver and that one only for the time and in the manner specifically stated. 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 
 13.1
Permanent Taking. If ten percent (10%) or more of the Premises or Building 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 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 upon one hundred eighty (180) days’ notice, provided such notice is given no later than one hundred eighty
(180) days after the date of such taking, condemnation, reconfiguration, vacation, deed or other instrument. If so much of the Premises is taken so as to substantially interfere with the conduct of Tenant’s business from the Premises, or
if access to the Premises is substantially impaired, Tenant shall have the option to terminate this Lease upon one hundred eighty (180) days’ notice, provided such notice is given no later than one hundred eighty (180) days after the
date of such taking. Landlord shall be entitled to receive the entire award or payment in connection therewith including the “Bonus Value” relating to the amount of the Base Rent, provided 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 claim is payable separately to Tenant. All Rent shall be apportioned as of the date of such termination, or the date of such taking, whichever shall first occur. 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. 

13.2 Temporary Taking. 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 

  
 32 

 
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 number 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, except that Tenant
shall have the right to file any separate claim available to Tenant for claims made by Tenant as a result of the necessity of Tenant’s moving to temporary space during the period of 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 such foregoing transfer of this Lease or any interest hereunder by operation of law, sublet the Premises or any part thereof,
or permit the use of the Premises by any persons other than Tenant and its employees (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 shall desire 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 ten (10) 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 a 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, financial statements from the proposed Transferee if necessary, under Section 14.2(iv), below, and a copy of all existing 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, and such other information as Landlord may
reasonably require. Any Transfer made without Landlord’s prior written consent shall, at Landlord’s option, be nun, void and of no effect. If Landlord shall grant consent, Tenant shall pay Landlord’s out-of-pocket reasonable legal
fees reasonably incurred by Landlord, within thirty (30) days after written request by Landlord. 
 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. Landlord shall notify Tenant in writing within fifteen (15) days
after Landlord’s receipt of a Transfer Notice as to whether Landlord consents to the proposed Transfer or withholds its consent thereto; failure of Landlord to so notify Tenant in writing within said fifteen (15) period shall be deemed to
constitute Landlord’s consent to the proposed Transfer 14.2.1 The parties hereby agree that, it shall not be reasonable under this Lease for Landlord to withhold its consent for any of the following reasons without implying that any other
grounds not set forth in this Section 14.2 are reasonable grounds for withholding consent: 
 (i) The assignment or sublease
occurs when any particular proportion of the Building or Project is not leased or is at economic terms which are not acceptable to Landlord for any reason; 

(ii) The terms of the proposed assignment or sublease will allow the proposed assignee to exercise an option to extend or expand held by
Tenant (or will allow the proposed subtenant to occupy space leased by Tenant pursuant to any such right); 
 (iii) 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 assignee or subtenant, (a) occupies space in the Project at the time of the request for consent, or
(b) is negotiating or has negotiate with Landlord to lease space in the Project; 
 (iv) The Subject Space for the proposed Transferee
is less than or equal to 75,000 rentable square feet, and the proposed Transferee (if such Transferee is subleasing space, as opposed to taking an assignment of the Lease) is not a party of adequate financial worth and/or financial stability; or

  
 33 

 (v) The proposed Transferee is either a governmental agency or instrumentality thereof, unless
such entity (i) is of a character or reputation, is engaged in a business, or is associated with a political orientation or faction, which is not consistent with the quality of the Building, or (ii) has the legal ability to exercise the
power of eminent domain or condemnation, or (iii) would significantly increase the human traffic in the Premises or Building. 
 It is
understood and agreed that, without limiting Landlord’s right of consent as provided herein, Landlord’s withholding consent shall be deemed reasonable if the proposed Transfer or the proposed use of the Premises by the proposed Transferee
shall conflict with or result in a breach of this Lease, or shall violate any exclusivity arrangements relating to retail uses that Landlord may then have with any retail tenant of the Building which exists as of the date hereof. 

If Landlord consents to any Transfer pursuant to the terms of this Section 14.2, 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 such that Landlord would initially have been entitled to refuse its
consent to such Transfer under this Section 14.2, Tenant shall again submit the Transfer to Landlord for its approval and other action under this Article 14. 

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 the amount 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 excess of the Rent (using a Base Rent figure of $24.00 per rentable square foot) and Additional Rent payable by Tenant under this Lease 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, and (ii) any brokerage commissions in
connection with the Transfer (iii) any costs to buy-out or takeover the previous lease of a Transferee, (iv) reasonable legal fees incurred in connection with the Transfer including those fees and costs reimbursed to Landlord pursuant to
the last sentence of Section 14.1, and (v) the amount of any Base Rent and Additional Rent paid by Tenant to Landlord with respect to the Subject Space during the period commencing on the later of (a) the date Tenant contracts with a
reputable broker to market the Subject Space, and (b) the date Tenant vacates the Subject Space, until the date six months after the commencement of the period, and (vi) any other “out-of-pocket” monetary concessions reasonably
provided in connection with the Transfer including, but not limited to, tenant improvement or decorating allowances (collectively, the “Subleasing Costs”). “Transfer Premium” shall also include, but not be limited to, key
money and bonus money 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. Tenant covenants that any allocation of payments or other consideration payable or deliverable to Tenant in connection with any subletting of the Premises or assignment of this Lease shall be
made in good faith and not with a purpose to avoid Tenant’s obligation to pay fifty percent (50%) of the Transfer Premium to Landlord. 

14.4 Effect of Transfer. If Landlord consents to a Transfer, (i) the terms and conditions of this Lease shall in no way be deemed
to have been waived or modified, (ii) such consent shall not be 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 setting forth in detail the computation of any Transfer Premium Tenant has derived
and shall derive from such Transfer, (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 liability under
this Lease, and (vi) such Transfer shall at all times be subject and subordinate to the terms of this Lease. 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 Landlord agrees, if set forth in, and required by, a written document between Tenant and a Transferee (the “Assignment Document”), (i) to amend

  
 34 

 
the notice blocks set forth on the first page of the Lease to add one (1) additional party and (ii) to deliver to the Tenant or its successor concurrently with the delivery thereof to
such Transferee, copies of any notices of default delivered pursuant to the terms of this Lease. Additionally, if requested of Landlord pursuant to the Assignment Document, the Transferee shall have the right to cure any default under this Lease
within the applicable cure period provided for the Tenant in this Lease. If the Assignment Document permits the Tenant to recover possession of the Premises and again become the “Tenant” under this Lease, Landlord agrees to accept Tenant
as the “Tenant” under this Lease pursuant thereto. 
 14.5 Assumption of Obligations. Each permitted assignee shall assume
all obligations of Tenant under this Lease with respect to the Premises. No Transfer shall be valid and no transferee shall take possession of the Premises or any part thereof unless, within ten (10) days after the execution of the documentary
evidence thereof, Tenant shall deliver to Landlord a duly executed duplicate original of the Transfer instrument in a form satisfactory to Landlord that (i) provides that the transferee assumes Tenant’s obligations for the payment of rent
(in the case of an assignment), and for the fun and faithful observance and performance of the covenants, terms and conditions contained herein, applicable to the Premises in the event of an assignment, and (ii) provides that an assignee will,
at Landlord’s election, attorn directly to landlord in the event this Lease is terminated for any reason on the terms set forth in the instrument of transfer. The failure or refusal of a transferee to execute such an instrument of assumption
shall not release or discharge the transferee from its obligations set forth above. 
 14.6 Non-Transfers. Notwithstanding anything
to the contrary contained in this Article 14, neither (i) an assignment or subletting of all or a portion of the Premises to an entity which is controlled by, controls, or is under common control with, Tenant, or to a purchaser of all or
substantially all of the assets of Tenant, or to an entity resulting, by operation of law or otherwise, from the merger, consolidation or other reorganization of Tenant (any such entity, an “Affiliate”), nor (ii) a transfer, by
law or otherwise, in connection with the merger, consolidation or other reorganization of Tenant or Affiliate, shall be deemed a Transfer under this Article 14, provided that such assignment, sublease or transfer is not a subterfuge by Tenant
to avoid its obligations under this Lease, and no such assignment, sublease or transfer shall relieve Tenant or any guarantor of this Lease from liability under this Lease. Tenant shall notify Landlord of any such assignment, sublease, action, or
use. “Control,” as used in this Section 14.6, shall mean the possession, direct or indirect, of the power to direct or cause the direction of the management and polices of a person or entity, or ownership of any sort, whether
through the ownership of voting securities, by contract or otherwise. 
 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 a writing signed 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. Tenant shall remove those items of furniture, furnishings, business machines and equipment, communications equipment and other articles of personal
property owned by Tenant or installed or placed by Tenant at its expense in the Premises (collectively, “Personal Property”) and Tenant shall remove Personal Property at times reasonably acceptable to Landlord and subject to the
availability of freight elevators, provided that Landlord shall insure that adequate hours for the usage of the freight elevator are made reasonably available to Tenant. 

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 and Section 8.5, above, quit and surrender possession of the Premises to Landlord in 

  
 35 

 
as good order and condition as when Tenant took possession and as thereafter improved by Landlord and/or Tenant, reasonable wear and tear, casualty and repairs which are specifically made the
responsibility of Landlord hereunder excepted. 
 15.3 Removal of Tenant’s Property by Landlord. Whenever Landlord shall
re-enter the Premises as provided in this Lease, any Personal Property not removed by Tenant upon the expiration of the Lease Term, or within forty-eight (48) hours after a termination by reason of Tenant’s default as provided in this
Lease, shall be deemed abandoned by Tenant and may be disposed of by Landlord in accordance with Sections 1980 through 1991 of the California Civil Code and Section 1174 of the California Code of Civil Procedure, or in accordance with any laws
or judicial decisions which may supplement or supplant those provisions from time to time. 
 15.4 Landlord’s Actions on
Premises. Tenant hereby waives all claims for damages or other liability in connection with Landlord’s reentering and taking possession of the Premises or removing, retaining, storing or selling the property of Tenant as herein provided.

 ARTICLE 16 

HOLDING OVER 
 If
Tenant holds over after the expiration of the Lease Term hereof, 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 Base Rent shall be payable at a monthly rate equal to one hundred twenty-five percent (125%) of the Base Rent applicable during the last rental period of the Lease Term under this Lease. Such month-to-month tenancy shall
be subject to every other 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. Tenant shall indemnify Landlord from and against all losses, costs, claims, liabilities, and expenses (including, without limitation, reasonable attorney’s fees, costs, and disbursements) sustained by
Landlord by reason of such holdover by Tenant (including, without limitation, claims for damages by any other person to whom Landlord may have agreed to lease an or any part of such portion of the premises effective on or after the date Tenant was
obligated to surrender possession thereof), but only to the extent such holdover continues more than sixty (60) days after the expiration of the then-current Lease Term. No acceptance by Landlord of rent during any such holding over without
Landlord’s consent shall reinstate, continue, or extend the Term of this Lease with respect to such portion of the Premises or shall affect any notice of termination given to Tenant prior to the payment of such money, it being agreed that after
the service of such notice or the commencement of any suit by Landlord to obtain possession of any portion of the Premise, Landlord may receive and collect when due any and all payments owed by Tenant under this Lease, and otherwise exercise its
rights and remedies. The making of any such payments by Tenant shall not waive such notice, or in any manner affect any pending suit or judgment obtained. 

ARTICLE 17 

ESTOPPEL CERTIFICATES 

Within thirty (30) days following a request in writing by Landlord, Tenant shall execute 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 required by any prospective mortgagee or purchaser of the Building, 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. Tenant shall execute and deliver whatever other
instruments may be reasonably required for such purposes. Failure of Tenant to timely execute and deliver such estoppel certificate or other instruments shall constitute an acceptance of the Premises and an acknowledgment by Tenant that statements
made in good faith included in the estoppel certificate are true and correct, without exception. Landlord hereby agrees to provide to Tenant an estoppel certificate signed by Landlord, containing the same types of information, and within

  
 36 

 
the same period of time, as set forth above, with such changes as are reasonably necessary to reflect that the estoppel certificate is being granted and signed by Landlord to Tenant, rather than
from Tenant to Landlord or a lender of Landlord. 
 ARTICLE 18 

SUBORDINATION 

This Lease is subject and subordinate to all present and future ground or underlying leases of the Real Property and to the lien of any
mortgages or trust deeds, now or hereafter in force against the Real Property and the Building, 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 or trust deeds, or the lessors under such ground lease or underlying leases, require in writing that this Lease be superior thereto. In consideration of, and as a
condition precedent to, Tenant’s agreement to permit its interest pursuant to this Lease to be subordinated to any particular future ground or underlying lease of the Building or the Real Property or to the lien of any first mortgage or trust
deed hereafter enforced against the Building or the Real Property and to any renewals, extensions, modifications, consolidations and replacements thereof, Landlord shall deliver to Tenant a non-disturbance agreement reasonably approved by Tenant
executed by the landlord under such ground lease or underlying lease or the holder of such mortgage or trust deed. Tenant hereby approves the form attached hereto as Exhibit R and any form substantially similar thereto. Except as may
be indicated in the form of agreement as Exhibit R hereto, each such non-disturbance agreement provided by Landlord shall acknowledge that Tenant may offset against Rent next owing under this Lease, (i) any unpaid commission due
and owing to Tenant’s Broker as set forth in Section 29.25, (ii) any abatements of Rent as allowed pursuant to Section 6.3.1 of this Lease, and (iii) any abatements of Rent as allowed pursuant to Section 7.2 of this
Lease. Tenant covenants and agrees in the event any proceedings are brought for the foreclosure of any such mortgage, to attorn, without any deductions or set-offs whatsoever, to the purchaser upon any such foreclosure sale if so requested to do so
by such purchaser, and to recognize such purchaser as the lessor under this Lease. Tenant shall, within thirty (30) 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. 

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, within five
(5) business days of notice that the same is due, which notice shall be in addition to and not in lieu of any notice required under California Code of Civil Procedure Section 1161 or any similar or successor law; provided, however, in the
event Tenant shall fail to make timely payment of rent more than two times in any twelve (12) consecutive month period, then for the remainder of such twelve (12) consecutive month period such five-day cure period shall be reduced to a
three (3) business day cure period; or 
 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 however, that any such notice shall be in addition to, and not in lieu of, any
notice required under California Code of Civil Procedure Section 1161 or any similar or successor law; and provided further 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 said default as soon as possible. 

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, 

  
 37 

 
the option to pursue anyone or more of the following remedies, each and all of which shall be cumulative and nonexclusive. 

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: 
 (i)
The worth at the time of award of any unpaid rent which has been earned at the time of such termination; plus 
 (ii) 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 

(iii) 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 
 (iv) Any other amount necessary to compensate
Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations under this Lease as allowed by applicable law; and 

(v) 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 Paragraphs 19.2.1(i) and (ii), above, the “worth at the time of award” shall be computed by allowing interest at the Interest
Rate. As used in Paragraph 19.2.1(iii) 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 (1%). 

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. 

19.3 Waiver of Default. No waiver by Landlord or Tenant of any violation or breach of any of the terms, provisions and covenants herein
contained shall be deemed or construed to constitute a waiver of any other or later violation or breach of the same or any other of the terms, provisions, and covenants herein contained. Forbearance by Landlord or Tenant in enforcement of one or
more of the remedies available to such party upon an event of default shall not be deemed or construed to constitute a waiver of such default. The acceptance of any Rent hereunder by Landlord following the occurrence of any default, whether or not
known to Landlord, shall not be deemed a waiver of any such default, except only a default in the payment of the Rent so accepted. Tenant hereby waives, for itself and all persons claiming by and under Tenant, all rights and privileges which it
might have under any present or future law to redeem the Premises or to continue the Lease after being dispossessed or ejected from the Premises by Landlord after the occurrence of an Event of Default. 

19.4 Efforts to Relet. For the purposes of this Article 19, Tenant’s right to possession shall not be deemed to have been
terminated by efforts of Landlord to relet the Premises, by its acts of maintenance or preservation with respect to the Premises, or by appointment of a receiver to protect Landlord’s interests hereunder. The foregoing enumeration is not
exhaustive, but merely illustrative of acts which may be performed by Landlord without terminating Tenant’s right to possession.

 ARTICLE 20  

COVENANT OF QUIET ENJOYMENT 

Landlord covenants that Tenant, on paying the Rent, charges for services and other payments herein reserved and on keeping, observing and
performing all the other terms, covenants, conditions, provisions and agreements herein contained on the part of Tenant to be kept, observed and performed, shall, during the Lease Term, peaceably and quietly have, hold and enjoy the Premises subject
to the terms, covenants, conditions, 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. 

ARTICLE 21  

REASONABLENESS AND GOOD FAITH 

Except for determinations expressly described as being in the “absolute discretion” of the applicable party, neither Landlord nor
Tenant shall unreasonably withhold or delay any consent, approval or other determination provided for hereunder, and determinations subject to absolute discretion shall not be unreasonably delayed. In the event that either Landlord or Tenant
disagrees with any determination made by the other hereunder (other than a determination in the absolute discretion of the determining party) and reasonably requests the reasons for such determination, the determining party shall furnish its reasons
in writing and in reasonable detail within five (5) business days following such request. Furthermore, in addition to the foregoing, whenever the Lease grants Landlord or Tenant the right to take action, exercise discretion, establish rules and
regulations, make allocations or other determinations, or otherwise exercise rights or fulfill obligations, Landlord and Tenant shall act reasonably and in good faith and take no action which might result in the frustration of the reasonable
expectations of a sophisticated landlord and sophisticated tenant concerning the benefits to be enjoyed under this Lease. 
 ARTICLE 22

 STORAGE SPACE 

Landlord shall reserve up to five thousand 5,000 square feet of storage space for lease by Tenant during the Lease Term (the
“Storage Space”). The Storage Space shall be located in one or more private rooms selected by Landlord in the On-Site Parking Area designated on Exhibit P attached hereto. Tenant shall have the right to increase
or decrease (but not in excess of the 5,000 square foot limit set forth above) the amount of Storage Space leased by Tenant on thirty (30) days written notice to Landlord. The Storage Space described above required to be provided by Landlord to
Tenant shall be leased at a rental rate equal to                     (            ) per
usable square foot per month during the Lease Tenn. Notwithstanding the foregoing, to the extent that any Storage Space in addition to the Storage Space required to be reserved by Landlord for Tenant’s use hereunder shall become available for
use by tenants of the Building, Landlord agrees that Tenant shall have the right, upon written notice to Landlord, to lease such additional Storage Space on a month-to-month basis to the extent and for the duration that Landlord does not require the
use of such additional Storage Space by other tenants in the Building or for another purpose. Any such additional Storage Space shall be leased at a rental rate equal to
                    (            ) per usable square foot per month. The Storage Space
rental amounts shall be due on a monthly basis concurrent with Tenant’s payment of the Base Rent due with respect to the Premises, and shall constitute Rent under the Lease. All Storage Space leased by Tenant shall be in a condition reasonably
suitable for use as storage space. Tenant acknowledges that Landlord, by providing Tenant with the Storage Space is not assuming the responsibility to ensure the security of or provide security for the Storage Space, and Tenant hereby waives all
claims against Landlord for damage to or theft of any property stored by Tenant in the Storage Space, except to the extent caused by the negligence or willful misconduct of Landlord or Landlord’s agents, contractors or representatives. Landlord
shall deliver the Storage Space to Tenant in its “as-is” condition, without any obligation on the part of Landlord to remodel, refurbish or otherwise improve the Storage Space, provided that the Storage Space shall have a ceiling, walls, a
door and lighting. Landlord shall have the right, not more than once per calendar year, upon thirty (30) days’ prior notice to Tenant, to relocate the Storage Space to another area of the Building of approximately the same aggregate square
footage as the Storage  

  
 39 

 
Space; in the event of such relocation of the Storage Space, Landlord shall pay Tenant’s actual costs of moving materials stored in the Storage Space to the replacement Storage Space. 

ARTICLE 23 

SIGNS 
 23.1
Interior of Premises. Tenant, at its sole cost and expense, may install identification signage anywhere in the Premises including in the elevator lobbies of the Premises, provided that such signs must not be visible from the exterior of the
Building. If other tenants occupy space on the floor on which the Premises is located, Tenant’s identifying signage shall be provided by Landlord, at Tenant’s cost, and shall comply with Landlord’s Building standard signage. 

23.2 Exterior of Premises. Commencing on a date which, in Tenant’s reasonable judgment, is necessary to allow
“Tenant’s Signage,” as that term is defined below, to be installed in and fully operational on the first day of the Pre-Occupancy Period, Tenant shall have an ongoing right to install (and replace) the name of Tenant and/or an
Affiliate, or an entity designated by Tenant (and, at Tenant’s sole discretion, Tenant’s logo), (“Tenant’s Signage Name”),at Tenant’s sole cost and expense, on the following signage (collectively,
“Tenant’s Signage”): (i) a sign in the ground floor elevator bank, and (ii)             monument signs on the exterior of the Building, all as further set
forth on Exhibit G attached hereto. The installation of Tenant’s Signage shall be subject to all laws and requirements of government authorities with jurisdiction over the Building. Notwithstanding anything to the contrary set
forth in the preceding sentence, Tenant shall be entitled to install additional signage in or outside of the Building in the location(s) depicted on Exhibit G, provided that the location, materials and design criteria thereof shall be
subject to Landlord’s approval, which shall not be unreasonably withheld or delayed. Tenant, at Tenant’s sole cost and expense, shall obtain all necessary government approvals and permits required for the installation and maintenance of
Tenant’s Signage; provided that Landlord shall use commercially reasonable efforts to assist Tenant in obtaining all necessary governmental permits and approvals for Tenant’s Signage. Tenant, at Tenant’s sole cost and expense, shall
maintain Tenant’s Signage in a first class manner and in compliance with all applicable laws and regulations, and shall pay the cost of all electricity, if any, consumed in connection with Tenant’s Signage. Upon the expiration or earlier
termination of the Lease, Tenant shall remove Tenant’s Signage from the Building and the Premises. 
 23.3
Transferability. The rights to the Tenant’s Signage (the “Signage Rights”), may be transferred by Tenant in their entirety to any Affiliate, or to any assignee or sublessee in connection with any assignment or sublease
of Tenant’s interest in this Lease which is permitted pursuant to the provisions of Article 14 of this Lease. 
 23.4 Directory
Board Space. Landlord shall provide Tenant, at no cost to Tenant, with space for a maximum of one (1) designated name per two thousand (2,000) rentable square feet of the Premises on the Building directory board located in the lobby of
the Building. Tenant will be permitted group and alphabetical listings on such directory board for Tenant’s professionals and any other employees, and listings for the names of any approved subtenants. 

23.5 Exclusivity. Tenant’s Signage Rights are exclusive to Tenant, any Affiliate and any transferee of Tenant’s interest in
this Lease. Therefore, except for all existing signage and reasonable modifications to such existing signage which is pursuant to Landlord’s standard signage program and does not identify a competitor of Tenant, Landlord shall not
(i) grant any signage rights to, (ii) consent to any granting of signage rights for, or (iii) permit any signage to be installed on behalf of, any tenants of the Real Property, or anyone else, anywhere on or in the Building, On-site
Parking Area or the Real Property, unless such signage is on the Building directory board or consist of Building standard identification signage located on the floor that a tenant in the Building occupies. For purposes of this Section 23.5, the
term “signage” shall include any logos or pictures which identify a tenant of the Real Property or anyone else.

 ARTICLE 24 

ARBITRATION 
 24.1
General Submittals to Arbitration. The submittal of all matters to arbitration in accordance with the terms of this Article 24 is the sole and exclusive method, means and procedure to resolve any and all claims, disputes or disagreements
arising under this Lease, including, but not limited to any defaults by Landlord, or any defaults by Tenant, except for (i) disputes for which a different resolution determination is specifically set forth in this Lease, (ii) all claims by
either party which (A) seek anything other than enforcement of rights under this Lease, or (B) are primarily founded upon matters of fraud, wilful misconduct, bad faith or any other allegations of tortious action, and seek the award of
punitive or exemplary damages, and (iii) claims relating to Landlord’s exercise of any unlawful detainer rights pursuant to California law or rights or remedies used by Landlord to gain possession of the Premises or terminate Tenant’s
right of possession to the Premises, which disputes shall be resolved by suit filed in the Superior Court of San Francisco County, California, the decision of which court shall be subject to appeal pursuant to applicable law. The parties hereby
irrevocably waive any and all rights to the contrary and shall at all times conduct themselves in strict, full, complete and timely accordance with the terms of this Article 24 and all attempts to circumvent the terms of this Article 24 shall be
absolutely null and void and of no force or effect whatsoever. As to any matter submitted to arbitration (except with respect to the payment of money) to determine whether a matter would, with the passage of time, constitute a default, such passage
of time shall not commence to run until any such affirmative arbitrated determination, as long as it is simultaneously determined in such arbitration that the challenge of such matter as a potential Tenant default was made in good faith. As to any
matter submitted to arbitration with respect to the payment of money, to determine whether a matter would, with the passage of time, constitute a default, such passage of time shall not commence to run in the event that the party which is obligated
to make the payment does in fact make the payment to the other party. Such payment can be made “under protest, II which shall occur when such payment is accompanied by a good faith notice stating the reasons that the party has elected to make a
payment under protest. Such protest will be deemed waived unless the subject matter identified in the protest is submitted to arbitration as set forth in this Article 24. 

24.2 JAMS. Any dispute to be arbitrated pursuant to the provisions of this Article 24 shall be determined by binding arbitration
before a retired judge of the Superior Court of the State of California (the “Arbitrator”) under the auspices of Judicial Arbitration & Mediation Services, Inc. (“JAMS”). Such arbitration shall be initiated
by the parties, or either of them, within ten (10) days after either party sends written notice (the “Arbitration Notice”) of a demand to arbitrate by registered or certified mail to the other party and to JAMS. The Arbitration
Notice shall contain a description of the subject matter of the arbitration, the dispute with respect thereto, the amount involved, if any, and the remedy or determination sought. The parties may agree on a retired judge from the JAMS panel. If they
are unable to promptly agree, JAMS will provide a list of three available judges and each party may strike one. The remaining judge (or if there are two, the one selected by JAMS) will serve as the Arbitrator. In the event that JAMS shall no longer
exist or if JAMS fails or refuses to accept submission of such dispute, then the dispute shall be resolved by binding arbitration before the American Arbitration Association (“AAA”) under the AAA’s commercial arbitration rules then in
effect. 
 24.3 Arbitration Procedure. 

24.3.1 Pre-Decision Actions. The Arbitrator shall schedule a pre-hearing conference to resolve procedural matters, arrange for the
exchange of information, obtain stipulations, and narrow the issues. The parties will submit proposed discovery schedules to the Arbitrator at the pre-hearing conference. The scope and duration of discovery will be within the sole discretion of the
Arbitrator. The Arbitrator shall have the discretion to order a pre-hearing exchange of information by the parties, including, without limitation, production of requested documents, exchange of summaries of testimony of proposed witnesses, and
examination by deposition of parties and third-party witnesses. This discretion shall be exercised in favor of discovery reasonable under the circumstances. 

24.3.2 The Decision. The arbitration shall be conducted in San Francisco, California. Any party may be represented by counselor other
authorized representative. In rendering a decision( s), the Arbitrator shall determine the rights and obligations of the parties 

  
 41 

 
according to the substantive and procedural laws of the State of California and the terms and provisions of this Lease. The Arbitrator’s decision shall be based on the evidence introduced at
the hearing, including all logical and reasonable inferences therefrom. The Arbitrator may make any determination, and/or grant any remedy or relief that is just and equitable. The decision must be based on, and accompanied by, a written statement
of decision explaining the factual and legal basis for the decision as to each of the principal controverted issues. The decision shall be conclusive and binding, and it may thereafter be confirmed as a judgment by the Superior Court of the State of
California, subject only to challenge on the grounds set forth in the California Code of Civil Procedure Section 1286.2. The validity and enforceability of the Arbitrator’s decision is to be determined exclusively by the California courts
pursuant to the provisions of this Lease. The Arbitrator may award costs, including without limitation attorneys’ fees, and expert and witness costs, to the prevailing party, if any, as determined by the Arbitrator in his discretion. The
Arbitrator’s fees and costs shall be paid by the non-prevailing party as determined by the Arbitrator in his discretion. A party shall be determined by the Arbitrator to be the prevailing party if its proposal for the resolution of dispute is
the closer to that adopted by the Arbitrator. To the extent Tenant is the prevailing party and receives a monetary award, and Landlord does not pay the amount of such award to Tenant within thirty (30) days after the date Tenant receives such
award, Tenant may deduct from the next Rent payable by Tenant under this Lease, the amount of such award. 
 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 within ten (l0) days after Tenant’s receipt of notice from Landlord that said amount is due, then Tenant shall pay to
Landlord a late charge equal to five percent (5%) of the amount due. The parties hereby agree that such late charge represents a fair and reasonable estimate of the costs that Landlord will incur by reason of the late payment of Rent by Tenant.
Acceptance of such late charge by Landlord shall in no event constitute a waiver of Tenant’s default with respect to such overdue amount, nor prevent Landlord from exercising any of the other rights and remedies granted hereunder. 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. 
 ARTICLE 26  

LANDLORD’S RIGHT TO CURE DEFAULT; PAYMENTS BY TENANT 

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 as otherwise provided in this Lease. If Tenant shall fail to perform any of its obligations under this Lease, within a reasonable time after such performance is required by the terms of this Lease,
Landlord may, but shall not be obligated to, after reasonable prior notice to Tenant, and the expiration of a reasonable cure period, make any such payment or perform any such act on Tenant’s part without waiving its right based upon any
default of Tenant and without releasing Tenant from any obligations hereunder. 
 ARTICLE 27 

ENTRY BY LANDLORD 

Landlord reserves the right at all reasonable times, upon reasonable notice to the Tenant, and in compliance with all other terms of this
Lease, to enter the Premises to (i) inspect them; (ii) show the Premises to prospective purchasers, mortgagees or ground or underlying lessors, or during the last six (6) months of the initial Lease Term (or Option Term, as
applicable), 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

to any breach of this Lease in the manner provided herein; and (C) perform any covenants of Tenant which Tenant 

  
 42 

 
fails to perform. Landlord may make any such entries without the abatement of Rent (except as otherwise provided herein) and may take such reasonable steps as required to accomplish the stated
purposes; provided, however, that any such entry shall be accomplished after business hours, as expeditiously as reasonably possible and in a manner so as to cause as little interference to Tenant as reasonably possible. Tenant hereby waives any
claims 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. 
 ARTICLE 28 

TENANT PARKING 

28.1 Number of Parking Spaces. Tenant shall be entitled, but not obligated, to rent Valet Spaces and/or Reserved Spaces on a monthly

 28.2 Parking Rate. Tenant shall pay to Landlord for automobile parking passes on a monthly basis the prevailing rate charged for
such Parking Passes; provided, however, that during the first ten (10) Lease Years, the monthly rates for such Parking Passes, inclusive of all taxes, shall be the lesser of (i) the prevailing parking rates charged by Landlord, and
(ii)                     (            ) per month for the Valet Spaces, and
(iii)                     (            ) per month for the Reserved Spaces. 

28.3 Use, Operation and Maintenance of On-site Parking Area. Tenant shall instruct its employees to abide by all rules and regulations
which are prescribed from time to time for the orderly operation and use of the On-site Parking Area. Landlord specifically reserves the right to reasonably change the size, configuration, design, layout and all other aspects of the On-site Parking
Area 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, temporarily close-off or restrict access to the On-site Parking
Area for purposes of permitting or facilitating any such construction, alteration or improvements so long as Landlord provides adequate substitute parking reasonably acceptable to Tenant. 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. 
 28.4
Transferability. 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; provided, however, Tenant may transfer a portion of the parking passes rented by Tenant pursuant to this Article 28 to an assignee or subtenant permitted pursuant to Article 14 of this Lease. Tenant agrees to
cooperate with Landlord in providing names of holders of the parking passes, license plate numbers and other reasonable information to Landlord so as to enable Landlord to monitor the On-Site Parking Area. 

28.5 Visitor Parking. Landlord shall provide visitor parking for Tenant’s visitors in an amount consistent with the Comparable

 28.6 Overselling. Landlord agrees not to sell monthly parking passes for the On-Site
Parking Area in an amount in excess of the product of (i) the number of stripped, legal size parking spaces in the On-Site Parking Area, and (ii) 1.20. Notwithstanding the foregoing, Landlord shall use its good faith efforts to not sell
more parking passes in the On-Site Parking Area than the numbers of parking spaces in the On-Site Parking Area. A reasonable amount of visitor parking shall be available in the Real Property and shall be at rates reasonably set by Landlord from time
to time and standard for all tenants of the Building. 
 ARTICLE 29

 FIRST AMENDMENT TO LEASE 

THIS FIRST AMENDMENT TO LEASE (“First Amendment”) is entered into as of June 20, 1997, by and between Rincon Center Associates,
a California limited partnership (“Landlord”), and National Union Fire Insurance Company of Pittsburgh, P .A., a Pennsylvania corporation (“Tenant”), with reference to the following facts: 

A. Landlord and Tenant entered into that certain Office Lease dated August 30, 1996 (the “Lease”), pursuant to which Landlord
leased to Tenant and Tenant leased from Landlord certain premises (the “Premises”) located in Two Rincon Center, San Francisco, California (the “Building”). The location of the Premises is more particularly described in the
Lease. 
 B. Landlord and Tenant desire to expand the Premises to include 18,565 rentable square feet of space located on the second
(2nd) floor of the Building (the “Expansion Premises”), as such space is more particularly shown on the floor plan attached hereto as Exhibit A. 

NOW, THEREFORE, in consideration of the foregoing, and for other good and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, Landlord and Tenant hereby agree as follows (capitalized terms used herein but not herein defined shall have the meaning ascribed to them in the Lease): 

1. Term. The term of the Lease with respect to the Expansion Premises shall commence on October 28, 1997 (the “Expansion
Premises Commencement Date”), and shall expire, unless sooner terminated, pursuant to the terms of the Lease, as of the date upon which the term of the Lease is fixed to expire. From and after the Expansion Premises Commencement Date, the
Expansion Premises shall be added to and deemed to be a part of the Premises; and references in the Lease to the “Premises” shall be deemed to include the Expansion Premises, unless the context clearly requires otherwise. Notwithstanding
the foregoing, Tenant shall have the right to occupy all or any portion of the Expansion Premises between July 1, 1997 and October 28, 1997, provided a certificate of occupancy has been issued for such portion of the Expansion Premises
which allows for such occupancy. Such early occupancy shall be on all the same terms and conditions of this First Amendment, except for Tenant’s obligation to pay Rent. 

2. Base Rent. From and after the Expansion Premises Commencement Date, Tenant shall pay as Base Rent for the Expansion Premises the sum
of                     per rentable square foot per year (i.e.,
                    per month) in accordance with the terms of the Lease. Notwithstanding the foregoing, for purpose of convenience only for the
Tenant, and with no intention whatsoever of modifying the rights and obligations of Landlord or Tenant in the Lease or this First Amendment, Landlord and Tenant agree to specify a “blended” Base Rent for the original Premises (i.e.
                    per rentable square foot per year times 154,928 rentable square feet) and the Expansion Premises (i.e.,
                    per rentable square foot per year times 18,565 rentable square feet) of
                    per rentable square foot per year for 173,493 rentable square feet. 

3. Tenant’s Proportionate Share. From and after the Expansion Premises Commencement Date, Tenant’s Share with respect to the
Expansion Premises shall be 9.68% and Tenant’s Share with respect to the Expansion Premises and the initial Premises combined shall be 90.97%, and the Base Year with respect to the Expansion Premises shall be the same Base Year as with respect
to the initial Premises under the terms of the Lease. 
 5. Improvement of Expansion Premises. 

(a) Improvements. Tenant, at Tenant’s sole cost and expense, shall construct improvements in the Expansion Premises (the
“Improvements”) in accordance with the terms of the Tenant Work Letter attached to the Lease as Exhibit B, with the following provisions expressly deleted: Section 1, Section 5, and Section 6.5. Tenant hereby agrees
to accept the Premises and the Building in an “as-is” condition, with no obligation to repair, remodel, alter or modify the Premises or the Building, except that Landlord, at its sole cost and expense, shall be responsible for remodeling
the restrooms on the second floor of the Building so as to comply with the Americans with Disabilities Act and with finishes of a standard similar to those of the other floors of the Building and for performing any work in the currently existing
common 

 
corridor on the second floor of the Building expressly required by governmental authorities so as to bring the corridor into compliance with all laws as of the Expansion Premises Commencement
Date. 
 6. Parking. The number “fifty” appearing in Section 11 of the Summary of Basic Lease information of the Lease
referring to the number of parking spaces provided to Tenant is hereby deleted and the number “fifty-six” is hereby substituted therefore. 

7. Brokerage. Tenant represents and warrants that it has dealt with no broker, agent or other person in connection with this
transaction and that no broker, agent or other person brought about this transaction, and Tenant agrees to indemnify and hold Landlord harmless from and against any claims by any broker, agent or other person claiming a commission or other form of
compensation by virtue of having dealt with Tenant with regard to this leasing transaction. The provisions of this paragraph shall survive the expiration or termination of this Lease. 

8. Landlord’s Right to Reimburse Tenant Improvements. 

(a) Exercise of Right. At any time during the initial Lease Term for the Expansion Premises, Landlord shall have the right
(“Reimbursement Right”) to reimburse Tenant for the costs of constructing the tenant improvements in the Expansion Premises (which shall be deemed equal to
                    per rentable square foot of the Expansion Premises) (hereinafter “Tenant Improvement Costs”). Landlord shall give
Tenant notice (the “Reimbursement Notice”) that Landlord exercises the Reimbursement Right effective as of the first day for the second (2nd) month following the date of delivery of the Reimbursement Notice to Tenant (the
“Effective Date”), the Base Rent for the Expansion Premises shall be increased to equal                     per rentable square foot, and
Landlord shall pay Tenant on the Effective Date an amount equal to the “Unamortized Value” as that term is defined in Section 8(b), below, as of the Effective Date of the Tenant Improvement Costs. 

(b) Calculation of Unamortized Value. The “Unamortized Value” of the Tenant Improvement Costs shall be equal to the product
of (i)                     per rentable square foot of the Expansion Premises and (ii) a fraction in which the numerator is (A) the
number of months remaining in the Lease Term as of one of the following dates, as applicable: (a) the Effective Date, (b) the date, if any, Tenant terminates the Lease pursuant to Section 11.2 of the Lease (the “Tenant
Termination Date”), or (c) the “Restoration Date,” as that term is defined in Section 11.1 of the Lease, and (B) the denominator is 116. 

9. Status of Lease. Except as amended hereby, the Lease remains unamended, and as amended hereby, the Lease and all the terms and
conditions thereof remain in full force and effect. 
 IN WITNESS WHEREOF, Landlord and Tenant have executed this First Amendment as of the
date first set forth above.

 TERMS 

NOW, THEREFORE, in consideration of the foregoing, and for other good and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, Landlord and Tenant hereby agree as follows (capitalized terms used herein but not herein defined shall have the meaning ascribed to them in the Lease): 

1. Recitals. The recitals are incorporated herein and made a part hereof. 

2. Parking. Article 28 of the Lease is hereby deleted and replaced with the following: 

ARTICLE 28 
 TENANT
PARKING 
 28.1 Number of Parking Spaces. Commencing as of May 1, 1999, Tenant shall be entitled to rent 53 Tandem Spaces
and Reserved Spaces on a monthly basis throughout the Lease Term. Landlord shall from time to time determine the ratio of Tandem Spaces and Reserved Spaces. As of the date of this Third Amendment, the ratio is 31 Reserved Spaces and 22 Tandem
Spaces. Landlord and Tenant agree that Landlord may adjust this ratio, not more than once per calendar year, by as much as twenty percent (20%). 

28.2 Parking Rate. Commencing as of May 1, 1999 and continuing through the initial lease term (thereafter, at the prevailing
market rate charged by Landlord), Tenant shall pay to Landlord for Parking Passes on a monthly basis the following rates, which rates are inclusive of all taxes:
                    Dollars ($        ) per month for the Tandem Spaces, and
                    Dollars ($        ) per month for the Reserved Spaces. 

28.3 Additional Parking. Landlord shall also make available to Tenant up to seven (7) additional Tandem Spaces and/or Reserved

28.4 Use Operation and Maintenance of On-Site Parking Area. Tenant shall instruct its employees to abide by all rules and regulations
which are prescribed from time to time for the orderly operation and use of the On-Site Parking Area. Landlord specifically reserves the right to reasonably change the size, configuration, design, layout and all other aspects of the On-site Parking
Area 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, temporarily close-off or restrict access to the On-Site

 
Parking Area for purposes of permitting or facilitating any such construction, alteration or improvements so long as Landlord provides adequate substitute parking reasonably acceptable to Tenant.
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. 

28.5 Transferability. 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; provided, however, Tenant may transfer a portion of the parking passes rented by Tenant
pursuant to this Article 28 to an assignee or subtenant permitted pursuant to Article 14 of this Lease. Tenant agrees to cooperate with Landlord in providing names of holders of the parking passes, license plate numbers and other reasonable
information to Landlord so as to enable Landlord to monitor the On-Site Parking Area. 
 28.6 Visitor Parking. Landlord shall provide
visitor parking for Tenant’s visitors in an amount consistent with the Comparable Buildings, subject to their payment of an hourly rate which shall not exceed the hourly rate generally charged in Comparable Buildings. 

28.7 Overselling. Landlord agrees not to sell monthly parking passes for the On-Site Parking Area in an amount in excess of the product
of (i) the number of stripped, legal size parking spaces in the On-Site Parking Area, and (ii) 1.20. Notwithstanding the foregoing, Landlord shall use its good faith efforts to not sell more parking passes in the On-Site Parking Area than
the number of parking spaces in the On-Site Parking Area. A reasonable amount of visitor parking shall be available in the Real Property and shall be at rates reasonably set by Landlord from time to time and standard for all tenants of the Building.

 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 undefined terms when used herein shall have the same respective meanings as are given such terms in the Lease unless expressly provided otherwise in this Fourth Amendment. 

2. Initial Termination Space. Landlord and Tenant hereby acknowledge and agree that, effective as of November 30, 2000 (the

which event (i) Landlord shall be permitted to complete the Initial Demising Work during normal business hours, without any obligation to pay overtime or other premiums, (ii) the completion of the Initial Demising Work shall in no way

equivalent compensation alleged to be owing on account of any dealings with any real estate broker or agent, occurring by, through, or under the indemnifying party. The terms of this Section 8 shall survive the expiration or earlier termination
of the Lease Term.

Initial Termination Space, (a) Tenant has not heretofore sublet the Initial Termination Space, nor assigned all or any portion of its interest in the Lease, as amended by this Fourth Amendment; (b) excluding Tenant’s Affiliates, as

multi-tenant corridor, which work may be simultaneous with Tenant’s construction in the Must-Take Premises, to a reasonable Building standard, as necessary to allow Tenant to legally occupy the Must-Take Premises as a separately demised suite
(the “Landlord Work”). Landlord shall coordinate with Tenant to minimize any interference with Tenant’s construction of improvements in the Must-Take Premises. In any event, Landlord shall have completed the Landlord Work in
advance of the “Must-Take Rent Commencement Date”, as defined below. If Landlord has not completed the Landlord Work as of the Must-Take Rent Commencement Date, the Must-Take Rent Commencement Date shall be extended on a day for day basis
until the Landlord Work is completed. As of the Must-Take Commencement Date, the Premises shall be deemed to be expanded to include the Must-Take Premises, and shall then contain approximately 161,019 rentable square feet of space, and Tenant’s
lease of the Must-Take Premises shall be on all of the terms and conditions of the Lease, as amended by this Amendment, provided that Tenant shall not be obligated to pay any Base Rent or Direct Expenses attributable to the Must-Take Premises until
the date (the “Must-Take Rent Commencement Date”) which is one hundred twenty (120) days after the Must-Take Commencement Date. Following the Must-Take Rent Commencement Date, Tenant shall pay Base Rent and Additional Rent
attributable to the Must-Take Premises in the same amounts per rentable square foot, and in the same manner, as is otherwise payable by Tenant with respect to the Premises. 

6.2 Construction in Must-Take Premises. Subject to the terms of the Tenant Work Letter, Tenant shall accept the Must-Take
Premises in its currently existing, “as-is” condition (subject to Landlord’s continuing repair and maintenance obligations as set forth in the Lease), and Landlord shall have no obligation to make any alterations or improvements
thereto, except that Landlord shall construct Landlord’s Work, which shall include ensuring code compliance for common area restrooms, as required in Landlord’s reasonable discretion, in accordance with Landlord’s building standard
specifications. Landlord shall provide Tenant

Term Commencement Date and continuing for six (6) months thereafter (the “Initial Rent Abatement Period”). Such abatement shall apply to the Existing Premises and Suite 290
leased as of the Extended Term Commencement Date only, and shall not apply to the Must-Take Premises. The total value of such rent abatement is the Base Rent payable during said six (6) month period (the “Rent Abatement”). At
Tenant’s option, exercisable by delivery of written notice thereof to Landlord within sixty (60) days after the full execution and delivery of this Amendment (the “Early Rent Abatement Notice”), Tenant shall have the right
to apply the entire amount of the Rent Abatement to Base Rent coming due under the Lease for the period commencing as of the date which is thirty (30) days after Tenant’s delivery of the Early Rent Abatement Notice, and continuing until
the value of the Rent Abatement has been fully credited against the Base Rent due during such period. In the event that Tenant so elects to utilize the Rent Abatement early, then Tenant shall have no right to receive any rent abatement during the
Initial Rent Abatement Period. 
 7.3 Tenant’s Share; Base Year. Prior to the Extended Term Commencement Date, Tenant
shall continue to pay Tenant’s Share of Direct Expenses in accordance with the terms of the Lease. Commencing as of the Extended Term Commencement Date, and continuing throughout the Extended Term, Tenant shall pay Tenant’s Share of Direct
Expenses for the Premises in accordance with the terms of the Lease, provided that (i) Tenant’s Share shall be amended to be equal to 68.62% (based on the 207,899 rentable square feet of office space contained in the Two Rincon Building),
and (ii) the Base Year shall be the fiscal year of July 1, 2007, through June 30, 2008. Notwithstanding the foregoing, effective as of the Must-Take Rent Commencement Date, Tenant’s Share shall be amended to be equal to 7.49%
(based on the 245,211 rentable square feet of office space contained in the One Rincon Building) for the portion of the Premises in the One Rincon Building, and 68.62% for the portion of the Premises in the Two Rincon Building. 

8. Option to Extend Term. Section 2.2 of the Office Lease is hereby deleted in its entirety, and replaced with the
following. 
 “2.2 Option Term. 

2.2.1 Option Right. Tenant shall have one (1) option to extend the Lease Term for a period of ten (10) years each (the
“Option Term”), which option shall be exercisable by written notice delivered by Tenant to Landlord as provided below. Upon the proper exercise of the option to extend, the Lease Term shall be extended by the Option Term, subject to
every term and condition of this Lease, except that the applicable “Option Rent,” as that term is defined in Section 2.2.1.3, below, shall be determined as set forth in Section 2.2.1.3, below. Tenant shall have the
right, exercisable concurrently with Tenant’s delivery of the “Option Notice,” as that term is defined below, to reduce the number of rentable square feet of office space which Tenant shall rent during the ensuing Option Term;
provided, however, that Tenant may only reduce the size of the Premises in full floor increments (or so much of a floor as shall be leased by Tenant in the event of less than full floor leasing) (the term “Renewal Space” shall mean
the portion of the Premises that Tenant elects to continue leasing for the Option Term). Tenant shall incur no penalty or charge in connection with the reduction in the size of the Premises during the ensuing Option Term. 

2.2.1.1 Exercise of Option. Subject to the terms of this Section 2.2.1.1, the option shall be exercised by Tenant in the
following manner: (i) Tenant shall deliver written notice to Landlord (the “Option Interest Notice”) not less than three hundred thirty (330) days prior to the expiration of the Lease Term (the “Option Interest
Notice Outside Date”), stating that (A) Tenant is interested in exercising its option and (B) the number of rentable square feet of the Premises, subject to the limitations set forth in Section 2.2.1, above, which
Tenant desires to lease during the Option Term; (ii) Landlord shall, after receipt of the Option 

  
 5 

 
Interest Notice, deliver written notice (the “Option Rent Notice”) to Tenant not less than three hundred (300) days prior to the expiration of the Lease Term (the
“Option Rent Notice Outside Date”), setting forth the proposed “Option Rent” as that term is defined in Section 2.2.1.2 below, which shall be applicable to this Lease during the Option Term, and
(iii) (A) Tenant may, at its option, on or before the date occurring two hundred seventy (270) days prior to the expiration of the Lease Term (the “Arbitration Notice Outside Date”), deliver a written notice to
Landlord (the “Fair Market Rent Arbitration Notice”), pursuant to which Fair Market Rent Arbitration Notice, Tenant may object to the proposed Option Rent or request the determination of Option Rent, if no Option Rent Notice was given
because Tenant did not give the Option Interest Notice, in either of which cases the parties shall follow the procedure, and the Option Rent shall be determined, as set forth in Section 2.2.2 of this Lease, or (B) to the extent the
terms of Section 2.2.2, below, are inapplicable (since Tenant did not deliver the Fair Market Rent Arbitration Notice), if Tenant wishes to exercise its extension option on the terms set forth in the Option Rent Notice, Tenant shall, on
or before the date occurring two hundred seventy (270) days prior to the expiration of the Lease Term (the “Exercise Notice Outside Date”), exercise the option by delivering written notice thereof to Landlord (the
“Option Exercise Notice”). Notwithstanding the foregoing terms of this Section 2.2.1.1, if the Renewal Space Tenant desires to lease during the Option Term consists of less than two (2) full floors, then for
purposes of Tenant exercising its option to extend the Lease Term, the outside dates set forth above shall refer to the following outside dates: (a) the Option Interest Notice Outside Date shall instead mean not less than four hundred
twenty-five (425) days prior to the expiration of the Lease Term; (b) the Option Rent Notice Outside Date shall mean not less than three hundred ninety-five (395) days prior to the expiration of the Lease Term; and (c) the
Arbitration Notice Outside Date or the Exercise Notice Outside Date shall mean three hundred sixty-five (365) days prior to the expiration of the Lease Term. In the event Tenant fails to exercise its right to extend the Lease Term for the
Option Term within the applicable time periods specified above, Tenant’s option rights as set forth in this Section 2.2.1.1 shall be terminated, and Tenant shall have no further rights pursuant to the terms of this Lease to extend the
Lease Term. 
 2.2.1.2 Termination of Option Right. Notwithstanding anything to the contrary contained herein, Tenant shall not be
allowed to exercise its option right and the Option Term shall not commence pursuant to the terms of this Section 2.2, if at the time Tenant gives Landlord the Option Exercise Notice, or the time the Option Term commences, as the case
may be, Tenant is in material default or monetary default of this Lease pursuant to the terms of Section 19.1 below, after the giving of written notice to Tenant by Landlord and the expiration of all applicable cure periods. 

2.2.1.3 Option Rent. The rent payable by Tenant during the Option Term (the “Option Rent”) shall be equal to
ninety-five percent (95%) of the then “Fair Market Rent.” “Fair Market Rent,” as used in this Lease, shall be equal to the rent, including escalations, if any, which tenants comparable to Tenant, as of the first day
of the applicable Option Term, are leasing for a comparable term, non-renewal, non-equity space comparable in size to the Premises, Renewal Space, First Offer Space, or “Management Office,” as that term is defined in
Section 4.2.4(38) of this Lease, as applicable, from a willing, comparable landlord, at arm’s length, which comparable space is located in the 

  
 6 

 
“Comparable Buildings,” as that .term is defined in Section 29.18, below, taking into consideration the following factors and considering all tenant concessions and
inducements given to tenants, including one hundred percent (100%) of the following concessions (which concessions Tenant, at its option, may take in the form as set forth below, or on an in-lieu cash up-front or rental credit basis of the same
value as the concession): (i) the amount of protection received by tenants in connection with the payment of operating and tax expenses (i.e. – base year or expense stop), (ii) rental abatement concessions being given such
tenants, if any, in connection with such comparable space and, as to First Offer Space only, in connection with the period of construction of such space, (iii) tenant improvement allowances and the value of tenant improvement work provided or
to be provided for such comparable space, provided that there shall be deducted from any such comparable space allowance or tenant improvement value, and Landlord shall receive credit for, the value of the then existing improvements, if any, in the
Premises, Renewal Space, or the First Offer Space, as applicable, regardless of whether the same were paid for or installed by Landlord or Tenant, with such value to be based upon the age, quality and layout of the improvements and the extent to
which the same could be utilized by a general office user (the “Existing Improvements Value”), (iv) all other tenant inducements and landlord concessions and payments made to tenants, including, but not limited to, lease
takeover payments, if any, being granted such tenants in connection with such comparable space, (v) the time the particular rental rate under consideration was agreed upon and became or is to become effective, (vi) the ratio of rentable
square feet to usable square feet; (vii) whether the lease transaction in question grants to the tenant any protection from increases in any component or all of real property taxes and operating expenses, and if so, the amount or value thereof;
and (viii) any other material factor, benefit or burden which a sophisticated tenant or landlord would believe would have a material impact on a determination of the current Fair Market Rent. 

2.2.2 Arbitration of Fair Market Rent. If the determination of Fair Market Rent is appropriately submitted to arbitration, Landlord and
Tenant shall each appoint one arbitrator who shall by profession be a real estate broker or MAI certified appraiser who shall have been active over the five (5) year period ending on the date of such appointment in the leasing or appraisal of
commercial high-rise properties in San Francisco, California. The determination of the arbitrators shall be limited solely to the issue of determining the actual Fair Market Rent for the applicable space, taking into account the requirements of
Section 2.2.1.3. Each such arbitrator shall be appointed within fifteen (15) days after Landlord’s receipt of the Fair Market Rent Arbitration Notice by each party delivering notice of its appointment to the other party. 

2.2.2.1 The two arbitrators so appointed shall within ten (10) days of the date of the appointment of the last appointed arbitrator agree
upon and appoint a third arbitrator who shall be qualified under the same criteria set forth hereinabove for qualification of the initial two (2) arbitrators. 

2.2.2.2 The three arbitrators shall within thirty (30) days of the appointment of the third arbitrator reach a decision as to the actual
Fair Market Rent and shall notify Landlord and Tenant thereof. 

  
 7 

 2.2.2.3 The decision of the majority of the three arbitrators shall be the decision of the
arbitrators and shall be binding upon Tenant and Landlord. 
 2.2.2.4 If either Landlord or Tenant fails to appoint an arbitrator within
fifteen (15) days after Landlord’s receipt of the Fair Market Rent Arbitration Notice, the arbitrator appointed by one of them shall reach a decision, and shall notify Landlord and Tenant thereof. Such arbitrator’s decision shall be
binding upon Tenant and Landlord. 
 2.2.2.5 If the two arbitrators fail to agree upon and appoint a third arbitrator, or both parties fail
to appoint an arbitrator, then the appointment of the third arbitrator or any arbitrator shall be dismissed and the matter to be decided shall be forthwith submitted to the arbitration procedures set forth in Article 24 of this Lease. Such decision
shall be binding on Tenant and Landlord. 
 2.2.2.6 The cost of arbitration shall be paid by Landlord and Tenant equally. 

2.2.2.7 If the amount of the Fair Market Rent is not determined within the time periods set forth above in this Section 2.2, and
continues to be undetermined as of the commencement of the Option Term, then Tenant shall continue to pay the existing Base Rent for the applicable Renewal Space until the amount of the Fair Market Rent is determined. When such determination is
made, if Tenant has underpaid the amount of Base Rent for the Option Term, then Tenant shall pay such deficiency to Landlord with Tenant’s payment of its next installment of Base Rent, or if Tenant has overpaid such Base Rent, then Landlord
shall either, at Landlord’s option, credit such overpayment in full against Tenant’s payment of Base Rent next coming due hereunder or pay such overpayment to Tenant upon demand. 

9. Parking. Commencing as of the Extended Term Commencement Date, Tenant shall have the right to 65 parking spaces (the
“Base Allotment”), and up to 7 additional spaces (the “Additional Spaces”), in accordance with the terms of the Lease, provided that as of the commencement of the Extended Term Commencement Date the monthly parking rate for the
Base Allotment only shall be (i) $        per month per car for non-reserved/valet Parking Passes, (ii) $        per month per car for reserved tandem Parking
Passes, and (iii) $        per month per car for Reserved Spaces. Such parking rates for the Base Allotment shall increased during the first three (3) years of the Extended Term. Thereafter, the
rates for all Parking Passes shall be adjusted to the then prevailing rates. Parking rates for the Additional Spaces, and any other additional spaces made available for lease to Tenant, and for the Base Allotment after the first three (3) years
of the Extended Term, shall be at the prevailing monthly rate for such spaces. The Base Allotment shall include 19 Tandem Spaces and 27 Reserved Spaces.s 

10. Right of First Offer. The right of first offer set forth in Section 1.6 of the Office Lease shall continue in full
force and effect, provided that, (i) in the first sentence of Section 1.6 of the Office Lease, the words “Two Rincon” are hereby inserted before the word “Building”, and (ii) as of the date hereof, Sections
1.6.1 and 1.6.2 of the Office Lease are hereby deleted in their entirety and replaced with the following: 
 “1.6.1
Procedure for Offer. Landlord shall notify Tenant in writing (the “First Offer Notice”) from time to time as soon as Landlord determines that any portion of the First Offer Space will become available for lease to third
parties provided, however, such notification shall be given not earlier than the date which is twelve (12) months before the actual date of physical availability of such First Offer Space. Pursuant to such First Offer Notice, Landlord shall
offer to lease to Tenant such First Offer Space. The First 

  
 8 

 
Offer Notice shall describe the space so offered to Tenant, shall set forth the “First Offer Rent,” as that term is defined in this Section 1.6.1, below, and shall set forth
the other terms upon which Landlord is willing to lease such space to Tenant, including the estimated delivery date of such space to Tenant, and the date upon which Tenant’s lease of such First Offer Space is to commence (the “First
Offer Commencement Date”), which First Offer Commencement Date shall not be less than ninety (90) days after the date such space is delivered to Tenant (which 90-day period may or may not be considered in determining the First Offer
Rent applicable to such space). The rent payable by Tenant for the First Offer Space (the “First Offer Rent”) shall be at the “Fair Market Rent” for the First Offer Space, as that term is defined in
Section 2.2.1.3 of this Office Lease (as amended by Section 8 of the Sixth Amendment to Office Lease). In addition to the foregoing, within five (5) business days after request by Tenant, Landlord shall provide to Tenant
in writing a listing (the “Available Space List”) of the First Offer Space that is then available for leasing or which Landlord reasonably believes will become available for leasing in the twenty-four (24) month period
following the date of Tenant’s request, and such Available Space List shall set forth the existing term expiration date, the number of any renewal options and their respective exercise mechanisms and dates, the term of any renewal options, and
a description of the specific additional space rights relating to the First Offer Space, for each then existing lease. Thereafter, Tenant may request that Landlord deliver to Tenant a specific First Offer Notice relating to any of the individual
spaces listed as First Offer Space on the Available Space List, and Landlord shall deliver a First Offer Notice within five (5) business days after such request by Tenant. 

1.6.2 Procedure for Acceptance. If Tenant wishes to exercise Tenant’s right of first offer with respect to the space described in
the First Offer Notice, then within fifteen (15) days after delivery of a particular First Offer Notice to Tenant, Tenant shall deliver written notice to Landlord of Tenant’s election to exercise its right of first offer with respect to
any specific portion of space as described in the First Offer Notice on the terms contained in such notice. In the event that, concurrently with Tenant’s exercise of the first offer right, Tenant notifies Landlord that it does not accept the
First Offer Rent set forth in the First Offer Notice, the First Offer Rent shall be determined in accordance with the procedures set forth in Section 2.2.2 of this Office Lease (as amended by Section 8 of the Sixth Amendment
to Office Lease); otherwise, the First Offer Rent shall be as set forth in Landlord’s First Offer Notice. If Tenant does not so notify Landlord within the fifteen (15) day period of Tenant’s exercise of its first offer right, then
Landlord shall be free to lease the space described in the First Offer Notice to anyone to whom Landlord desires on any terms Landlord desires, for a period of one hundred eighty (180) days commencing upon the expiration of the fifteen
(15) day period, after which time Tenant’s rights to such space under this Section 1.6 shall renew.” 
 11.
Right to Expand Premises. Landlord hereby grants Tenant the right to lease (i) approximately 21,334 rentable square feet of space located on the second (2nd) floor of the Two Rincon Building (the “Luce Expansion
Space”), and (ii) between 9,000 and 12,000 rentable square feet of space located on the fourth (4th) floor of the Two Rincon Building (the “State Expansion Space”), upon the terms and conditions set forth in this
Section 11. As used herein, the term “Expansion Space” may refer to either the Luce Expansion Space or State Expansion Space, as the context dictates.

11.1.1 Luce Expansion Space. The right to lease the Luce Expansion Space shall be exercised only in the following manner:
(i) Tenant shall deliver written notice to Landlord on or before April 30, 2009, stating that Tenant is interested in exercising its option (the “Expansion Interest Notice”); (ii) Landlord, after receipt of the
Expansion Interest Notice, shall deliver written notice (the “Expansion Rent Notice”) to Tenant on or before June 1, 2009, setting forth the “Expansion Rent,” as that term is defined in Section 11.3 below,
applicable to the Luce Expansion Space; and (iii) if Tenant wishes to lease the Luce Expansion Space, Tenant shall, on or before the date which is thirty (30) days after Tenant’s receipt of such Expansion Rent Notice, exercise the
option by delivering written notice thereof to Landlord (the “Expansion Exercise Notice”). At Tenant’s option, concurrently with the delivery of the Expansion Exercise Notice, Tenant may object to the Expansion Rent set forth
in the Expansion Rent Notice, in which case the Expansion Rent shall be determined as set forth in Section 2.2.2 of the Office Lease (as amended by the terms of Section 8 of this Amendment). 

11.1.2 State Expansion Space. The right to lease the State Expansion Space shall be exercised only in the following manner:
(i) Tenant shall deliver an Expansion Interest Notice, relating to the State Expansion Space, to Landlord on or before the date (the “State Expansion Exercise Date”) which is the earlier of (a) June 30, 2011, and
(b) the date which is thirty (30) days after the date upon which Landlord notifies Tenant that the State of California has elected to terminate its existing lease of the State Expansion Space (and Landlord shall notify Tenant promptly in
writing upon the State of California’s exercise of such early termination right), stating that Tenant is interested in exercising its option; (ii) Landlord, after receipt of the Expansion Interest Notice, shall deliver an Expansion Rent
Notice to Tenant within thirty (30) days after receipt of the Expansion Interest Notice, setting forth the Expansion Rent applicable to the State Expansion Space and designating the size and location of the State Expansion Space; and
(iii) if Tenant wishes to lease the State Expansion Space, Tenant shall, on or before the date which is thirty (30) days after Tenant’s receipt of such Expansion Rent Notice, exercise the option by delivering an Expansion Exercise
Notice with respect to such State Expansion Space. (Commencing as of July 31, 2010, the State of California has a continuing right to terminate its lease of the State Expansion Space on 90 days prior notice. The State of California’s lease
of the State Expansion Space will otherwise terminate effective as of July 31, 2012.) At Tenant’s option, concurrently with the delivery of the Expansion Exercise Notice, Tenant may object to the Expansion Rent set forth in the Expansion
Rent Notice, in which case the Expansion Rent shall be determined as set forth in Section 2.2.2 of the Office Lease (as amended by the terms of Section 8 of this Amendment). 

11.2 Delivery of the Expansion Space. Landlord shall deliver the applicable Expansion Space to Tenant as soon as reasonably
practicable following the vacation and surrender thereof by the existing tenant therein. 
 11.3 Expansion Rent. The Rent
payable by Tenant for Expansion Space leased by Tenant (the “Expansion Rent”) shall be equal to     % of the                 for
such space (as defined in Section 2.2.1.3 of the Office Lease, as amended by the terms of Section 8 of this Amendment). 

11.4 Construction in the Expansion Space. Tenant shall take any Expansion Space in its then existing, “as is”
condition (subject to Landlord’s continuing repair and maintenance obligations as set forth in the Lease), subject to any improvement allowance granted in connection therewith as a component of the Expansion Rent, and the construction of
improvements in the Expansion Space shall comply with the terms of the Tenant Work Letter. 
 11.5 Amendment to Lease. If
Tenant timely exercises Tenant’s right to lease the Expansion Space as set forth herein, Landlord and Tenant shall promptly thereafter execute an amendment adding such Expansion Space to the Lease upon the same terms and conditions as the
Existing Premises and Suite 290, except as otherwise set forth in this Section 11. The rent commencement date for any Expansion Space leased by Tenant hereunder shall be the date which is ninety (90) days after the date such
Expansion Space is delivered to Tenant by Landlord (which 90-day period shall be considered in determining the applicable Expansion Rent). 

11.6 No Defaults. Tenant shall not have the right to lease Expansion Space as provided in this Section 11, if, as of
the date of the attempted exercise of the expansion option by 

  
 10 

 
Tenant, or as of the scheduled date of delivery of such Expansion Space to Tenant, Tenant is in default under the Lease, as amended, after expiration of any applicable notice or cure periods.

 12. Downsize Right. The Downsize Right set forth in Section 1.3 of the Office Lease shall continue in full
force and effect provided that (i) such right shall not commence until after the fifth (5th) full year of the Extended Term, and (ii) as a condition precedent to any reduction of
the Premises as set forth therein, Tenant shall deliver to Landlord, on or before the applicable Downsize Termination Date, a fee (the “Downsize Fee”) equal to the
                as of the applicable Downsize Termination Date, of the
                and                 (including the
                paid by Landlord with respect to this Amendment. In determining such
“                ,” the sum of the                 and
                shall be deemed to be amortized over the entire Extended Term of the Lease, commencing as of the Extended Term Commencement Date with respect to the
Existing Premises and Suite 290, and commencing as of the Must Take Rent Commencement Date with respect to the Must-Take Premises. 
 13.
Storage Space. The rights contained in Article 22 of the Office Lease shall continue in full force and effect, provided that (i) the rental rate applicable to any Storage Space leased by Tenant shall be equal to
$        per usable square foot per month (the “Storage Rent”), which Storage Rent shall be increased, as of each anniversary of the Extended Term Commencement Date, to be 103% of the prior
amount of the Storage Rent, and (ii) the Storage Space to be leased by Tenant, at Tenant’s option, shall consist of up to approximately 5,738 rentable, and 4,878 usable, square feet of space to be located in the area reasonably designated
by Landlord in accordance with the terms of Article 22 of the Office Lease. 
 14. Landlord’s Security. Landlord
shall continue to provide the “Landlord’s Security”, as defined in Section 6.1.7 of the Office Lease, during the Extended Term, which Landlord’s Security shall include the number of personnel and the general access
control procedures in place as of the date of this Amendment (which numbers and procedures shall not be materially modified without the prior written consent of Tenant, which shall not be unreasonably withheld, conditioned or delayed). In addition,
Landlord shall, at Landlord’s sole cost and expense, cause the Two Rincon Building elevators to require “key cards” for access to the 3rd, 5th and 6th floors of the Two Rincon Building, and any future floors of the Buildings which are
leased in their entirety by Tenant. The actual key cards to be issued to Tenant’s employees shall be at Tenant’s sole cost and expense. At Tenant’s option, Tenant shall have the right, at Tenant’s sale cost and expense, to cause
the southern elevators in the One Rincon Building (i.e., the elevators solely serving the Premises in the One Rincon Building) to require “key cards” for access to the Premises (the “One Rincon Elevator Security”).
Tenant’s installation of the One Rincon Elevator Security shall be in accordance with all of the applicable terms of the Lease, and subject to Landlord’s prior approval of the design and installation thereof (which shall not be
unreasonably withheld). The One Rincon Elevator Security shall be compatible with the Project security systems. The maintenance and repair of the One Rincon Elevator Security shall be at Tenant’s sole cost and expense. At the end of the term or
earlier expiration of the Lease, Landlord shall have the right, at Landlord’s option, to cause Tenant to remove the One Rincon Elevator Security and to repair any damage to the elevators caused by the installation or removal of the One Rincon
Elevator Security. 
 15. Brokers. Section 29.25 of the Lease is hereby deleted, and shall be of no further force
or effect. The following provisions shall apply to this Amendment. 
 15.1 Landlord shall pay, pursuant to a separate written agreement, a
commission owed to CB Richard Ellis, Inc. (“Tenant’s Broker”) (the “Landlord Obligations”). Landlord and Tenant each represent and warrant to the other that other than Tenant’s Broker and CAC Group
(representing Landlord), no broker, agent, or finder negotiated or was instrumental in negotiating or consummating this Amendment on its behalf and that it knows of no broker, agent, or finder, other than Tenant’s Broker or the CAC Group, who
