 ARTICLE 1 

PREMISES, BUILDING, PROJECT, AND COMMON AREAS 

1.1    Premises, Building, Project and Common Areas. 

1.1.1    The Premises. Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the premises
set forth in Section 2.2 of the Summary (the “Premises”). The outline of the Premises is set forth in Exhibit A attached hereto and each floor or floors of the
Premises has the number of rentable square feet as set forth in Section 2.2 of the Summary. The parties hereto agree that the lease of the Premises is upon and subject to the terms, covenants and conditions herein set forth, and Tenant
covenants as a material part of the consideration for this Lease to keep and perform each and all of such terms, covenants and conditions by it to be kept and performed. The parties hereto hereby acknowledge that the purpose of
Exhibit A is to show the approximate location of the Premises in the “Building,” as that term is defined in Section 1.1.2, below, only, and such Exhibit is not
meant to constitute an agreement, representation or warranty as to the construction of the Premises, the precise area thereof or the specific location of the “Common Areas,” as that term is defined in
Section 1.1.3, below, or the elements thereof or of the accessways to the Premises or the “Project,” as that term is defined in Section 1.1.2, below. Except as specifically set forth in
this Lease and in the Tenant Work Letter attached hereto as Exhibit B (the “Tenant Work Letter”), Tenant shall accept the Premises in its presently existing “as-is” condition and Landlord shall not be obligated to provide or pay for any improvement work or services related to the improvement of the Premises. Tenant also acknowledges that neither Landlord nor
any agent of Landlord has made any representation or warranty regarding the condition of the Premises, the Building or the Project or with respect to the suitability of any of the foregoing for the conduct of Tenant’s business, except as
specifically set forth in this Lease and the Tenant Work Letter. The taking of possession of the Premises by Tenant shall conclusively establish that the Premises and the Building were at such time in good and sanitary order, condition and repair,
subject to Landlord’s obligations under Article 7 (including Landlord’s obligations with respect to the maintenance of the Building Systems serving the Premises and the Building Structure) of this Lease and the Tenant Work Letter. 

1.1.2    The Building and The Project. The Premises are a part of the building set forth in
Section 2.1 of the Summary (the “Building”). The Building is part of an office project known as “Gateway Center.” The term “Project,” as used in this Lease, shall mean
(i) the Building and the Common Areas, (ii) the land (which is improved with landscaping, subterranean parking facilities and other improvements) upon which the Building and the Common Areas are located, (iii) those certain other
office buildings located in the vicinity of the Building and known as 601 Gateway Boulevard and 651 Gateway Boulevard, respectively, and the land upon which such office buildings are located, and (iv) at Landlord’s discretion, any
additional real property, areas, land, buildings or other improvements added thereto outside of the Project. 

1.1.3    Common Areas. Tenant shall have the non-exclusive right to
use in common with other tenants in the Project, and subject to the rules and regulations referred to in Article 5 of this Lease, those portions of the Project which are provided, from time to time, for use in common by
Landlord, Tenant and any other tenants of the Project (such areas, together 

  

					
		  	-5-	  	 611 GATEWAY

[CATALYST BIOSCIENCES INC.]
 SF
LEGAL/JH-MY










 
with such other portions of the Project designated by Landlord, in its discretion, including certain areas designated for the exclusive use of certain tenants, or to be shared by Landlord and
certain tenants, are collectively referred to herein as the “Common Areas”). The Common Areas shall consist of the “Project Common Areas” and the “Building Common Areas.” The term “Project Common
Areas,” as used in this Lease, shall mean the portion of the Project designated as such by Landlord, which Project Common Areas may include, from time to time, in Landlord’s sole discretion, a conference center and other amenities. The
term “Building Common Areas,” as used in this Lease, shall mean the portions of the Common Areas located within the Building designated as such by Landlord. The manner in which the Common Areas are maintained and operated shall be
at the sole, but reasonable discretion of Landlord and the use thereof shall be subject to such rules, regulations and restrictions as Landlord may make from time to time; provided, however, that Landlord shall maintain the Common Areas consistent
with the standards of a “Class A” office building; and further provided, that there shall be no fee charged for Tenant to use the Common Areas other than Tenant’s Share of Building Direct Expenses set forth in Article 4,
below. Landlord reserves the right to close temporarily, make alterations or additions to, or change the location of elements of the Project and the Common Areas; provided, however, that in doing so, Landlord shall use commercially reasonable
efforts to minimize any material interference with Tenant’s access to and use of the Premises. 

1.2    Rentable Square Feet of Premises and Building. For purposes of this Lease, “rentable square
feet” in the Premises and the Building, as the case may be, shall be calculated pursuant to Landlord’s then current commercially reasonable method for measuring rentable square footage. Landlord and Tenant hereby stipulate and agree
that the rentable area of the Premises is as set forth in Section 2.2 of the Summary. 
 ARTICLE 2 

LEASE TERM 
 The
terms and provisions of this Lease shall be effective as of the date of this Lease. The term of this Lease (the “Lease Term”) shall commence on the “Lease Commencement Date,” as that term is set forth in
Section 3.2 of the Summary, and shall terminate on the “Lease Expiration Date,” as that term is set forth in Section 3.3 of the Summary, unless this Lease is sooner terminated as
hereinafter provided. Landlord shall, however, deliver exclusive possession of the Premises to Tenant (subject to access by Landlord Parties to perform the Landlord Work) on or before the date that is one (1) business day after the mutual
execution and delivery of this Lease by Landlord and Tenant (the “Delivery Date”). From the Delivery Date through the date immediately preceding the Lease Commencement Date (the “Early Occupancy Period”), Tenant
shall have the right to use and occupy the Premises for the design, construction and installation of the Tenant Improvements and other to prepare the Premises for the conduct of Tenant’s business. All of the terms and conditions of this Lease
shall apply during the Early Occupancy Period, except that Tenant shall have no obligation to pay Base Rent or Tenant’s Share of Building Direct Expenses. If Landlord is unable for any reason to deliver possession of the Premises to Tenant on
any specific date, then Landlord shall not be subject to any liability for its failure to do so, and such failure shall not affect the validity of this Lease or the obligations of Tenant hereunder. For purposes of this Lease, the term “Lease
Year” shall mean each

LEGAL/JH-MY










 
consecutive twelve (12) month period during the Lease Term. At any time during the Lease Term, Landlord may deliver to Tenant a notice in the form as set forth in
Exhibit C, attached hereto, as a confirmation only of the information set forth therein, which Tenant shall execute (or object to) and return to Landlord within ten (10) business days of receipt
thereof; provided, however, Tenant’s failure to execute and return such notice to Landlord within such time shall be conclusive upon Tenant that the information set forth in such notice is as specified therein. 

ARTICLE 3 
 BASE RENT

 3.1    Base Rent. Commencing on the Lease Commencement Date, Tenant shall pay, without prior
notice or demand, base rent (“Base Rent”) as set forth in Section 4 of the Summary, payable in equal monthly installments as set forth in Section 4 of the Summary in advance on or before the first day of each and every
calendar month during the Lease Term, without any setoff or deduction whatsoever (except as otherwise expressly provided in this Lease). The Base Rent for the third full month of the Lease Term shall be paid at the time of Tenant’s execution of
this Lease. If any Rent payment date (including the Lease Commencement Date) falls on a day of the month other than the first day of such month or if any payment of Rent is for a period which is shorter than one month, the Rent for any fractional
month shall accrue on a daily basis for the period from the date such payment is due to the end of such calendar month or to the end of the Lease Term at a rate per day which is equal to 1/365 of the applicable annual Rent. All other payments or
adjustments required to be made under the terms of this Lease that require proration on a time basis shall be prorated on the same basis. Until notice of some other designation is given to Tenant in accordance with the provisions of Article 28 of
this Lease, Base Rent and all other charges shall be paid by remittance to or for the order of BXP 611 GATEWAY CENTER LLC by one of the following methods:

 3.2    Abated Base Rent. Provided that Tenant is not then in default of this
Lease beyond any applicable notice and cure periods, then during the first two (2) full calendar month(s) of the Lease Term (the “Rent Abatement Period”), Tenant shall not be obligated to pay any Base Rent otherwise
attributable to the Premises during such Rent Abatement Period (the “Rent Abatement”). Landlord and Tenant acknowledge that the aggregate amount of the Rent Abatement equals $59,381.40. Tenant acknowledges and agrees that the
foregoing Rent Abatement has been granted to Tenant as additional consideration for entering into this Lease, and for agreeing to pay the rental and performing the terms and conditions otherwise required under this Lease. If Tenant shall be in
default under this Lease and shall fail to cure such default within the notice and cure period, if any, permitted for cure pursuant to this Lease, or if this Lease is terminated as a result of a default by Tenant under this Lease, then the dollar
amount of the unapplied portion of the Rent Abatement as of the date of such default or termination, as the case may be, shall be converted to a credit to be applied to the Base Rent applicable at the end of the Lease Term and Tenant shall
immediately be obligated to begin paying Base Rent for the Premises in full. 
 ARTICLE 4 

ADDITIONAL RENT 

4.1    General Terms. In addition to paying the Base Rent specified in Article 3
of this Lease, Tenant shall pay, without duplication, (i) ”Tenant’s Share” of the annual “Building Direct Expenses,” as those terms are defined in Sections 4.2.10 and 4.2.2 of this Lease,
respectively, which are in excess of the amount of Building Direct Expenses applicable to the “Base Year,” as that term is defined in Section 4.2.1 of this Lease, and (ii) Tenant’s Share of “Capital
Expenses,” as that term is defined in Section 4.2.9, below, pursuant to Section 4.6 of this Lease; provided, however, that in no event shall any decrease in Building Direct Expenses for any
“Expense Year,” as that term is defined in Section 4.2.6 of this Lease, below Building Direct Expenses for the Base Year entitle Tenant to any decrease in Base Rent or any credit against sums due under this Lease.
Such payments by Tenant, together with any and all other amounts payable by Tenant to Landlord pursuant to the terms of this Lease, are hereinafter collectively referred to as the “Additional Rent,” and the Base Rent and the
Additional Rent are herein collectively referred to as “Rent.” All amounts due under this Article 4 as Additional Rent shall be payable for the same periods and in the same manner as the Base Rent. Without
limitation on other obligations of Tenant which survive the expiration of the Lease Term, the obligations of Tenant to pay the Additional Rent provided for in this Article 4 shall survive the expiration of the Lease

LEGAL/JH-MY










 
Term. Landlord may upon expiration of the Lease Term deliver to Tenant an estimate of any Base Rent, Additional Rent or other obligations outstanding, and Landlord may either deduct such amount
from any funds otherwise payable to Tenant upon expiration or require Tenant to pay such funds immediately. Landlord shall make necessary adjustments for differences between actual and estimated Additional Rent in accordance with
Section 4.4, below. 
 4.2    Definitions of Key Terms Relating to Additional
Rent. 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 5 of the
Summary. 
 4.2.2    “Building Direct Expenses” shall mean “Building Operating Expenses” and
“Building Tax Expenses”, as those terms are defined in Sections 4.2.3 and 4.2.4, below, respectively. 

4.2.3    “Building Operating Expenses” shall mean the portion of “Operating Expenses,” as that
term is defined in Section 4.2.7 below, allocated to the tenants of the Building pursuant to the terms of Section 4.3.1 below.

such change, Tenant’s Share of Building Direct Expenses and Capital Expenses shall be equitably adjusted for any Expense Year involved in any such change. 

4.2.7    “Operating Expenses” shall mean all expenses, costs and amounts of every kind and nature which
Landlord actually pays or accrues during any Expense Year because of or in connection with the ownership, management, maintenance, security, repair, replacement, restoration or operation of the Project, or any portion thereof. Without limiting the

 If Landlord is not furnishing any particular work or service (the cost of
which, if performed by Landlord, would be included in Operating Expenses) to a tenant who has undertaken to perform such work or service in lieu of the performance thereof by Landlord, Operating Expenses shall be deemed to be increased by an amount

incurred had the Project been one hundred percent (100%) occupied; and the amount so determined shall be deemed to have been the amount of Operating Expenses for such year. Operating Expenses for the Base Year shall not include market-wide cost
increases (including utility rate increases) due to extraordinary circumstances, including, but not limited to, Force Majeure, boycotts, strikes, conservation surcharges, security concerns, embargoes or shortages. In no event shall the components of

 4.2.8    Taxes. 

4.2.8.1    “Tax Expenses” shall mean all federal, state, county, or local governmental or municipal
taxes, fees, charges or other impositions of every kind and nature, whether general, special, ordinary or extraordinary (including, without limitation, real estate taxes, general and special assessments, transit taxes, business taxes, leasehold
taxes or taxes based upon the receipt of rent, including gross receipts or sales taxes applicable to the receipt of rent, unless required to be paid by Tenant, personal property taxes imposed upon the fixtures, machinery, equipment, apparatus,
systems and equipment, appurtenances, furniture and other personal property used in connection with the Project, or any portion thereof), which shall be paid or accrued during any Expense Year (without regard to any different fiscal year used by
such governmental or municipal authority) because of or in connection with the ownership, leasing and operation of the Project, or any portion thereof. All assessments which can be paid by Landlord in installments shall be paid by Landlord in the
maximum number of installments permitted by law (except to the extent inconsistent with the general practice of landlords of the Comparable Buildings) and shall be included as Tax Expenses in the year in which the assessment is actually paid. 

4.2.8.2    Tax Expenses shall include, without limitation: (i) Any tax on the rent, right to rent or other income
from the Project, or any portion thereof, or as against the business of leasing the Project, or any portion thereof; (ii) Any assessment, tax, fee, levy or charge in addition to, or in substitution, partially or totally, of any assessment, tax,
fee, levy or charge previously included within the definition of real property tax, it being acknowledged by Tenant and Landlord that Proposition 13 was adopted by the voters of the State of California in the June 1978 election (“Proposition
13”) and that assessments, taxes, fees, levies and charges may be imposed by governmental agencies for such services as fire protection, street, sidewalk and road maintenance, refuse removal and for other governmental services formerly
provided without charge to property owners or occupants, and, in further recognition of the decrease in the level and quality of governmental services and amenities as a result of Proposition 13, Tax Expenses shall also include any governmental or
private assessments or the Project’s contribution towards a governmental or private cost-sharing agreement for the purpose of augmenting or improving the quality of services and amenities normally provided by governmental agencies;
(iii) Any assessment, tax, fee, levy, or charge allocable to or measured by the area of the Premises, the tenant improvements in the Premises, or the Rent payable hereunder, including, without limitation, any business or gross income tax or

thereof for any reason, including, without limitation, error or reassessment by applicable governmental or municipal authorities, Tenant

shall pay Landlord upon demand Tenant’s Share of any such increased Tax Expenses properly included by Landlord as Building Tax Expenses pursuant to the terms of this Lease. Notwithstanding
anything to the contrary contained in this Section 4.2.8 (except as set forth in Section 4.2.8.1, above), there shall be excluded from Tax Expenses (i) all excess profits taxes, franchise
taxes, gift taxes, transfer taxes, capital stock taxes, inheritance and succession taxes, estate taxes, federal and state income taxes, and other taxes to the extent applicable to Landlord’s general or net income (as opposed to rents, receipts
or income attributable to operations at the Project), (ii) any items included as Operating Expenses, (iii) any items paid by Tenant under Section 4.5 of this Lease, (iv) tax penalties incurred as a result of
Landlord’s failure to make payments and/or to file any tax or informational returns when due, (v) special assessments levied against another tenant or occupant in the Building due to improvements made by such other tenant or occupant, or
otherwise. 
 4.2.8.4    Notwithstanding anything to the contrary set forth in this Lease, the amount of Tax Expenses
for the Base Year and any Expense Year shall be calculated without taking into account any decreases in real estate taxes obtained in connection with Proposition 8, and, therefore, the Tax Expenses in the Base Year and/or an Expense Year may be
greater than those actually incurred by Landlord, but shall, nonetheless, be the Tax Expenses due under this Lease; provided that (i) any costs and expenses incurred by Landlord in securing any Proposition 8 reduction shall not be deducted from
Tax Expenses nor included in Direct Expenses for purposes of this Lease, and (ii) tax refunds under Proposition 8 shall not be deducted from Tax Expenses nor refunded to Tenant, but rather shall be the sole property of Landlord. Landlord and
Tenant acknowledge that the preceding sentence is not intended to in any way affect (A) the inclusion in Tax Expenses of the statutory two percent (2.0%) annual increase in Tax Expenses (as such statutory increase may be modified by subsequent
legislation), or (B) the inclusion or exclusion of Tax Expenses pursuant to the terms of Proposition 13. Notwithstanding anything to the contrary set forth in this Lease, only Landlord may institute proceedings to reduce Tax Expenses and the
filing of any such proceeding by Tenant without Landlord’s consent shall constitute an event of default by Tenant under this Lease. Notwithstanding the foregoing, Landlord shall not be obligated to file any application or institute any
proceeding seeking a reduction in Tax Expenses. Notwithstanding the foregoing, upon a reassessment of the Building and/or the Project pursuant to the terms of Proposition 13 (a “Reassessment”) occurring after the Base Year which
results in a decrease in Tax Expenses, the component of Tax Expenses for the Base Year which is attributable to the assessed value of the Building and/or the Project under Proposition 13 prior to the Reassessment (without taking into account any
Proposition 8 reductions) (the “Base Year Prop 13 Taxes”) shall be reduced, if at all, for the purposes of comparison to all subsequent Expense Years (commencing with the Expense Year in which the Reassessment takes place) to an
amount equal to the real estate taxes based upon such Reassessment, and if thereafter, in connection with a subsequent Reassessment, the assessed value of the Building and/or the Project under Proposition 13 shall increase, the current Base Year
Prop 13 Taxes shall be increased for purposes of comparison to all subsequent Expense Years (commencing with the Expense Year in which the Reassessment takes place) to an amount equal to the lesser of the original Base Year Prop 13 Taxes and an
amount equal to the real estate taxes based upon such Reassessment.

 4.2.9    “Capital Expenses” shall mean all cost of capital
repair, improvements or expenditures incurred by Landlord in connection with the Project (A) which are intended to effect economies in the operation, cleaning or maintenance of the Project, or any portion thereof, (B) that are required to
comply with governmentally-mandated conservation programs, (C) which are replacements or modifications of nonstructural items located in the Common Areas required to keep the Common Areas in good order or condition, or (D) that are
required under any governmental law or regulation. In no event shall Capital Expenses include any costs incurred by Landlord prior to or during the Base Year. 

4.2.10    “Tenant’s Share” shall mean the percentage set forth in
Section 6 of the Summary. Tenant’s Share was calculated by multiplying the number of rentable square feet of the Premises, as set forth in Section 2.2 of the Summary, by 100, and dividing the
product by the total number of rentable square feet in the Building. 
 4.3    Allocation of Direct
Expenses. 
 4.3.1    Method of Allocation. The parties acknowledge that the Building is a part of
a multi-building project and that the costs and expenses incurred in connection with the Project (i.e., the Direct Expenses) should be shared between the tenants of the Building and the tenants of the other buildings in the Project.
Accordingly, as set forth in Section 4.2 above, Direct Expenses (which consists of Operating Expenses and Tax Expenses) are determined annually for the Project as a whole, and a portion of the Direct Expenses, which portion
shall be determined by Landlord on an equitable basis, shall be allocated to the tenants of the Building (as opposed to the tenants of any other buildings in the Project) and such portion shall be the Building Direct Expenses for purposes of this
Lease. Such portion of Direct Expenses allocated to the tenants of the Building shall include all Direct Expenses attributable solely to the Building and an equitable portion of the Direct Expenses attributable to the Project as a whole. 

4.3.2    Cost Pools. Landlord shall have the right, from time to time, to equitably allocate some or all of
the Direct Expenses for the Project among different portions or occupants of the Project (the “Cost Pools”), in Landlord’s reasonable discretion. Such Cost Pools may include, but shall not be limited to, the office space
tenants of a building of the Project or of the Project, and the retail space tenants of a building of the Project or of the Project. The Direct Expenses allocable to each such Cost Pool shall be allocated to such Cost Pool and charged to the tenants
within such Cost Pool in an equitable manner. 
 4.4    Calculation and Payment of Direct Expenses. If for
any Expense Year ending or commencing within the Lease Term, Tenant’s Share of Building Direct Expenses for such Expense Year exceeds Tenant’s Share of Building Direct Expenses applicable to the Base Year, then Tenant shall pay to
Landlord, in the manner set forth in Section 4.4.1, below, and as Additional Rent, an amount equal to the excess (the “Excess”). 

4.4.1    Statement of Actual Building Direct Expenses and Payment by Tenant. Landlord shall give to Tenant
within one hundred twenty days following the end of each Expense Year, a statement (the “Statement”) which shall state the Building Direct Expenses incurred or accrued for such preceding Expense Year, and which shall indicate the
amount of the Excess. Upon receipt of the Statement for each Expense Year commencing or

ending during the Lease Term, if an Excess is present, Tenant shall pay, with its next installment of Base Rent due or within thirty (30) days, whichever is earlier, the full amount of the
Excess for such Expense Year, less the amounts, if any, paid during such Expense Year as “Estimated Excess,” as that term is defined in Section 4.4.2, below. If the amounts paid by Tenant during an Expense Year as
Estimated Excess exceed the Excess for such Expense Year, then such difference shall be reimbursed by Landlord to Tenant within thirty (30) days after the date on which Landlord receives a written request from Tenant for such difference,
provided that any such reimbursement, at Landlord’s option, may be credited against the Rent next coming due under this Lease unless the Lease Term has expired, in which event Landlord shall refund the appropriate amount to Tenant. The failure
of Landlord to timely furnish the Statement for any Expense Year shall not prejudice Landlord or Tenant from enforcing its rights under this Article 4. Even though the Lease Term has expired and Tenant has vacated the
Premises, when the final determination is made of Tenant’s Share of Building Direct Expenses for the Expense Year in which this Lease terminates, if an Excess is present, Tenant shall pay to Landlord such amount within thirty (30) days
after receipt of Landlord’s invoice. The provisions of this Section 4.4.1 shall survive the expiration or earlier termination of the Lease Term. 

4.4.2    Statement of Estimated Building Direct Expenses. In addition, Landlord shall endeavor to give
Tenant a yearly expense estimate statement (the “Estimate Statement”) which shall set forth Landlord’s reasonable estimate (the “Estimate”) of what the total amount of Building Direct Expenses for the
then-current Expense Year shall be and the estimated excess (the “Estimated Excess”) as calculated by comparing the Building Direct Expenses for such Expense Year, which shall be based upon the Estimate, to the amount of Building
Direct Expenses for the Base Year. The failure of Landlord to timely furnish the Estimate Statement for any Expense Year shall not preclude Landlord from enforcing its rights to collect any Estimated Excess under this
Article 4, nor shall Landlord be prohibited from revising any Estimate Statement or Estimated Excess theretofore delivered to the extent necessary. Thereafter, Tenant shall pay, with its next installment of Base Rent due, a
fraction of the Estimated Excess for the then-current Expense Year (reduced by any amounts paid pursuant to the last sentence of this Section 4.4.2). Such fraction shall have as its numerator the number of months which have
elapsed in such current Expense Year, including the month of such payment, and twelve (12) as its denominator. Until a new Estimate Statement is furnished (which Landlord shall have the right to deliver to Tenant at any time), Tenant shall pay
monthly, with the monthly Base Rent installments, an amount equal to one-twelfth (1/12) of the total Estimated Excess set forth in the previous Estimate Statement delivered by Landlord to Tenant. 

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

4.5.1    Tenant shall be liable for and shall pay ten (10) days before delinquency, taxes levied against Tenant’s
equipment, furniture, fixtures and any other personal property located in or about the Premises. If any such taxes on Tenant’s equipment, furniture, fixtures and any other personal property are levied against Landlord or Landlord’s
property or if the assessed value of Landlord’s property is increased by the inclusion therein of a value placed upon such equipment, furniture, fixtures or any other personal property and if Landlord pays the taxes based upon such increased
assessment, which Landlord shall have the right to do regardless of the validity thereof but only under proper protest if requested by Tenant, Tenant shall within thirty (30) days after demand repay to Landlord the taxes so levied against
Landlord or the proportion of such taxes resulting from such increase in the assessment, as the case may be.

 4.5.2    If the tenant improvements in the Premises, whether installed and/or
paid for by Landlord or Tenant and whether or not affixed to the real property so as to become a part thereof, are assessed for real property tax purposes at a valuation higher than the valuation at which tenant improvements conforming to
Landlord’s “building standard” in other space in the Building are assessed, then the Tax Expenses levied against Landlord or the property by reason of such excess assessed valuation shall be deemed to be taxes levied against personal
property of Tenant and shall be governed by the provisions of Section 4.5.1, above. 

4.5.3    Notwithstanding any contrary provision herein, Tenant shall pay prior to delinquency any (i) rent tax or
sales tax, service tax, transfer tax or value added tax, business tax or any other applicable tax on the rent or services herein or otherwise respecting this Lease, (ii) taxes assessed upon or with respect to the possession, leasing, operation,
management, maintenance, alteration, repair, use or occupancy by Tenant of the Premises or any portion of the Project, including the Project parking facility; or (iii) taxes assessed upon this transaction or any document to which Tenant is a
party creating or transferring an interest or an estate in the Premises. 
 4.6    Calculation and Payment of
Capital Expenses. Notwithstanding any provision to the contrary contained in this Lease, Tenant shall pay to Landlord, on a monthly basis. as Additional Rent and in addition to Tenant’s Share of Building Direct Expenses, an amount equal
to Tenant’s Share of all Capital Expenses incurred by Landlord for any Expense Year following the Base Year; provided, however, any such Capital Expenses shall be amortized (including interest on the unamortized cost at an annual interest rate
reasonably determined by Landlord) over its useful life as Landlord shall reasonably determine, and Tenant shall only be obligated to pay Tenant’s Share of such amortized amount; provided further, however, if Landlord reasonably concludes on
the basis of engineering estimates that a particular capital expenditure will effect savings in Operating Expenses, including, without limitation, energy related costs, and that such projected savings will, on an annual basis (“Projected
Annual Savings”), exceed the annual amortization therefor, then and in such event the amount of amortization for such capital expenditure shall be increased to an amount equal to the Projected Annual Savings; and in such circumstance, the
increased amortization (in the amount of the Projected Annual Savings) shall be made for such period of time as it would take to fully amortize the cost of the item in question, together with interest thereon at the interest rate as aforesaid in
equal monthly payments, each in the amount of 1/12th of the Projected Annual Savings, with such payment to be applied first to interest and the balance to principal. The amount of Capital Expenses incurred by Landlord, as well as Tenant’s Share
of such Capital Expenses, shall be set forth on each Statement and each Estimate Statement delivered by Landlord Tenant and Tenant shall pay Tenant’s Share of such Capital Expenses at the same time and in the same manner as Tenant shall pay
Tenant’s Share of Building Direct Expenses.

first obtaining Landlord’s written consent. Tenant shall immediately notify, and shall direct Tenant’s agents, employees contractors, invitees, assignees and sublessees to immediately notify, Landlord of any incident in, on or about the
Premises, the Building or the Project that would require the filing of a notice under any federal, state, local or quasi-governmental law (whether under common law, statute or otherwise), ordinance, decree, code, ruling, award, rule, regulation or
guidance document now or hereafter enacted or promulgated, as amended from time to time, in any way relating to or regulating any Hazardous Substance. As used herein, “Hazardous Substance” means any substance which is toxic,
ignitable, reactive, or corrosive and which is regulated by any local government, the State of California, or the United States government. “Hazardous Substance” includes any and all material or substances which are defined as
“hazardous waste,” “extremely hazardous waste” or a “hazardous substance” pursuant to state, federal or local governmental law. “Hazardous Substance” also includes asbestos, polychlorobiphenyls (i.e.,
PCB’s) and petroleum.

 6.1.1    Subject to limitations imposed by all governmental rules,
regulations and guidelines applicable thereto, Landlord shall provide heating, ventilation and air conditioning (“HVAC”) when necessary for normal comfort for normal office use in the Premises from 7:00 A.M. to 6:00 P.M. Monday

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 incidental use equipment) for lighting and power suitable for the Permitted Use as reasonably determined by Landlord, provided that Tenant’s electrical usage shall be subject to
applicable laws and regulations. Tenant shall bear the cost of replacement of lamps, starters and ballasts for non-Building standard lighting fixtures within the Premises. 

6.1.3    Landlord shall provide city water from the regular Building outlets for drinking, lavatory and toilet purposes in
the Building Common Areas. 
 6.1.4    Landlord shall provide nonexclusive,

Tenant shall have access to the Building, the Premises and the Common Areas of the Building, other than Common Areas requiring access with a Building engineer, twenty-four (24) hours per day, seven (7) days per week, every day of the year;
provided, however, that Tenant shall only be permitted to have access to and use of the freight elevator, loading dock, mailroom and other limited-access areas of the Building during the normal operating hours of such portions of the Building. 

Notwithstanding anything in this Lease to the contrary, if Landlord or any affiliate of Landlord has elected to qualify as a real estate investment trust
(“REIT”), any service required or permitted to be performed by Landlord pursuant to this Lease, the charge or cost of which may be treated as impermissible tenant service income under the laws governing a REIT, may be

performed by a taxable REIT subsidiary that is affiliated with either Landlord or Landlord’s property manager, an independent contractor of Landlord or Landlord’s property manager (the
“Service Provider”). If Tenant is subject to a charge under this Lease for any such service, then, at Landlord’s direction, Tenant will pay such charge either to Landlord for further payment to the Service Provider or directly
to the Service Provider, and, in either case, (i) Landlord will credit such payment against Rent due from Tenant under this Lease for such service, and (ii) such payment to the Service Provider will not relieve Landlord from any obligation
under the Lease concerning the provisions of such service. 
 6.2    Overstandard Tenant Use. Tenant shall
not, without Landlord’s prior written consent, use heat-generating machines, machines other than normal fractional horsepower office machines, or equipment or lighting other than Building standard lights in the Premises, which may affect the
temperature otherwise maintained by the air conditioning system or increase the water normally furnished for the Premises by Landlord pursuant to the terms of Section 6.1 of this Lease. If Tenant uses water, electricity,
heat or air conditioning in excess of that supplied by Landlord pursuant to Section 6.1 of this Lease, Tenant shall pay to Landlord, upon billing, the cost of such excess consumption, the cost of the installation,
operation, and maintenance of equipment which is installed in order to supply such excess consumption, and the cost of the increased wear and tear on existing equipment caused by such excess consumption; and Landlord may install devices to
separately meter (or sub-meter) any increased use and in such event Tenant shall pay the increased cost directly to Landlord, within thirty (30) days after demand, at the rates charged by the public
utility company furnishing the same, including the cost of such additional metering (or sub-metering) devices. In addition, in the event that there is located in the Premises a data center containing high
density computing equipment, as defined in the U.S. EPA’s Energy Star® rating system (“Energy Star”), Landlord may require the installation in accordance with Energy Star
of separate metering or check metering equipment, in which event (i) Tenant shall pay the costs of any such meter or check meter directly to Landlord, within thirty (30) days after demand, including the installation and connectivity
thereof, (ii) Tenant shall directly pay to the utility provider all electric consumption on any meter, and (iii) Tenant shall pay to Landlord, as Additional Rent, all electric consumption on any check meter within thirty (30) days
after being billed thereof by Landlord, in addition to other electric charges payable by Tenant under the Lease. In the event that Tenant purchases any utility service directly from the provider, Tenant shall promptly provide to Landlord either
permission to access Tenant’s usage information from the utility service provider or copies of the utility bills for Tenant’s usage of such services in a format reasonably acceptable to Landlord. Tenant’s use of electricity shall
never exceed the capacity of the feeders to the Project or the risers or wiring installation, and subject to the terms of Section 29.32, below, Tenant shall not install or use or permit the installation or use of any
computer or electronic data processing equipment in the Premises, without the prior written consent of Landlord; provided, however, the foregoing restriction shall not apply to normal and customary general office use of printers and personal
computers on the desktops of Tenant’s employees and computer and related equipment in Tenant’s server room. If Tenant desires to use heat, ventilation or air conditioning during hours other than those for which Landlord is obligated to
supply such utilities pursuant to the terms of Section 6.1 of this Lease, Tenant shall give Landlord such prior notice (not to exceed one (1) business day), if any, as Landlord shall from time to time reasonably
establish as appropriate, of Tenant’s desired use in order to supply such utilities, and Landlord shall supply such utilities to

Tenant at such hourly cost to Tenant (which shall be treated as Additional Rent) as Landlord shall from time to time establish. Landlord shall have the exclusive right, but not the obligation, to
provide any additional services to the Premises which may be required by Tenant, including, without limitation, locksmithing, lamp replacement, additional janitorial service, and additional repairs and maintenance. If Tenant requests any such
additional services, then Tenant shall pay to Landlord the reasonable cost of such additional services, including Landlord’s standard fee for its involvement with such additional services, promptly upon being billed for same. If Tenant installs
any supplemental HVAC units for a server room and/or network equipment, the after-hours charges referenced in Section 2 of Exhibit F attached hereto shall not apply to any such system. 

6.3    Interruption of Use. 

6.3.1    No Liability. Except as specifically provided to the contrary in this
Section 6.3, Tenant agrees that Landlord shall not be liable for damages, by abatement of Rent or otherwise, for failure to furnish or delay in furnishing any service (including telephone and telecommunication services), or
for any diminution in the quality or quantity thereof, when such failure or delay or diminution is occasioned, in whole or in part, by breakage, repairs, replacements, or improvements, by any strike, lockout or other labor trouble, by inability to
secure electricity, gas, water, or other fuel at the Building or Project after reasonable effort to do so, by any riot or other dangerous condition, emergency, accident or casualty whatsoever, by act or default of Tenant or other parties, or by any
other cause beyond Landlord’s reasonable control; and such failures or delays or diminution shall never be deemed to constitute an eviction or disturbance of Tenant’s use and possession of the Premises or relieve Tenant from paying Rent or
performing any of its obligations under this Lease, provided that nothing herein shall be construed as diminishing the repair and maintenance obligations of Landlord hereunder. Furthermore, Landlord shall not be liable under any circumstances for a
loss of, or injury to, property or for injury to, or interference with, Tenant’s business, including, without limitation, loss of profits, however occurring, through or in connection with or incidental to a failure to furnish any of the
services or utilities as set forth in this Article 6. 
 6.3.2    Abatement of
Rent. In the event of any failure to furnish or delay in furnishing any service (including telephone and telecommunication services) as specified in Section 6.3.1, above, or any diminution in the quality or quantity
thereof, which is caused by the negligence or willful misconduct of Landlord, its employees, agents or contractors, and as a result thereof Tenant is prevented from using, and does not use, the Premises or any portion thereof (such set of
circumstances to be known as an “Abatement Event”), then Tenant shall give Landlord notice of such Abatement Event, and if such Abatement Event continues for five (5) consecutive business days after Landlord’s receipt of
any such notice (the “Eligibility Period”), then the Base Rent and Tenant’s Share of Direct Expenses shall be abated or reduced, as the case may be, after expiration of the Eligibility Period for such time that Tenant continues
to be so prevented from using, and does not use for the normal conduct of Tenant’s business, the Premises or a portion thereof, in the proportion that the rentable area of the portion of the Premises that Tenant is prevented from using, and
does not use, bears to the total rentable area of the Premises. Such right to abate Base Rent and Tenant’s Share of Direct Expenses shall be Tenant’s sole and exclusive remedy for rent abatement at law or in equity for an Abatement Event.
Except as provided in this Section 6.3.2, nothing contained herein shall be interpreted to mean that Tenant is excused from paying Rent due hereunder.

 ARTICLE 7 

REPAIRS 
 Landlord
shall at all times during the Lease Term maintain in good condition and operating order the structural portions of the Building, including, without limitation, the foundation, floor slabs, ceilings, roof, columns, beams, shafts, stairs, stairwells,
escalators, elevators, base building restrooms and all Common Areas (collectively, the “Building Structure”), and the Base Building mechanical, electrical, life safety, plumbing, sprinkler and HVAC systems installed or furnished by
Landlord (collectively, the “Building Systems”). Except as specifically set forth in this Lease to the contrary, Tenant shall not be required to pay for the repair of the Building Structure and/or the Building Systems except to the
extent required because of Tenant’s use of the Premises for other than the Permitted Use set forth in Section 7 of the Summary. If any such repairs to the Building Systems or Building Structure shall be required, they shall be performed by
Landlord and not by Tenant. Tenant shall, at Tenant’s own expense, keep the Premises, including all improvements, fixtures and furnishings therein, in good order, repair and condition at all times during the Lease Term. In addition, Tenant
shall, at Tenant’s own expense, but under the supervision and subject to the prior approval of Landlord, and within any reasonable period of time specified by Landlord, promptly and adequately repair all damage to the Premises and replace or
repair all damaged, broken, or worn fixtures and appurtenances, except for damage caused by ordinary wear and tear or beyond the reasonable control of Tenant; provided however, that, Landlord shall have the exclusive right, at Landlord’s
option, but not the obligation, to make such repairs and replacements, and Tenant shall pay to Landlord the cost thereof, including Landlord’s standard fee for its involvement with such repairs and replacements, promptly upon being billed for
same. In the event Landlord does not elect to make such repairs and replacements, then such repairs shall be performed by a contractor (and subcontractors, as necessary) retained by Tenant from the list of contractors approved by Landlord. Such
contractor(s) shall follow Landlord’s reasonable and non-discriminatory construction administration procedures and utilize the standard specifications and details for the Building, all as promulgated by
Landlord from time to time. Landlord may, but shall not be required to, enter the Premises at all reasonable times to make such repairs, alterations, improvements or additions to the Premises or to the Project or to any equipment located in the
Project as Landlord shall desire or deem necessary or as Landlord may be required to do by governmental or quasi-governmental authority or court order or decree. In performing all repair and maintenance obligations required of Landlord under this
Article 7, Landlord shall use commercially reasonable efforts to minimize interference with the conduct of Tenant’s business. Tenant hereby waives any and all rights under and benefits of subsection 1 of Section 1932 and
Sections 1941 and 1942 of the California Civil Code or under any similar law, statute, or ordinance now or hereafter in effect.

 ARTICLE 8 

ADDITIONS AND ALTERATIONS 

8.1    Landlord’s Consent to Alterations. Tenant may not make or suffer to be made any improvements,
alterations, additions, changes, or repairs (pursuant to Article 7 or otherwise) to the Premises or any mechanical, plumbing or HVAC facilities or systems pertaining to the Premises (collectively, the “Alterations”) without
first procuring the prior written consent of Landlord to such Alterations, which consent shall be requested by Tenant in accordance with the terms and conditions of this Article 8, and which consent shall not be
unreasonably withheld, conditioned or delayed by Landlord, provided it shall be deemed reasonable for Landlord to withhold its consent to any Alteration which adversely affects the structural portions or the systems or equipment of the Building or
is visible from the exterior of the Building. Landlord may impose, as a condition of its consent to any and all Alterations or repairs of the Premises or about the Premises, such requirements as Landlord in its reasonable discretion may deem
necessary. Notwithstanding the foregoing, Tenant shall be permitted, not more often than once per calendar year, to make Alterations without Landlord’s prior consent, to the extent that such Alterations (i) do not, in the aggregate, exceed
a cost of $25,000.00 per Alteration, (ii) do not affect the Building Systems or Building Structure, (iii) do not affect the exterior appearance of the Premises or the Building, and (iv) do not require the issuance of any permits,
approvals or other documents by any governmental agency; provided, however, that the Tenant shall first give ten (10) business days’ prior written notice to the Landlord specifying the proposed Alterations, the commencement and approximate
completion dates thereof, and in any event any such Alterations by the Tenant shall be made in accordance with all applicable laws and in a good and first-class, workmanlike manner and in accordance with this Lease. 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    Manner of Construction. Prior to the commencement of construction of any Alterations or repairs,
Tenant shall submit to Landlord, for Landlord’s review and approval in its reasonable discretion, four (4) copies signed by Tenant of all plans, specifications and working drawings relating thereto. Tenant, at its sole cost and expense,
shall retain an architect/space planner selected by Tenant, and reasonably approved by Landlord, to prepare such plans, specifications and working drawings; provided that, Tenant shall also retain the engineering consultants from a list provided by
Landlord to prepare all plans and engineering working drawings, if any, relating to the structural, mechanical, electrical, plumbing, HVAC, life safety and sprinkler work of the Alterations. Tenant shall be required to include in its contracts with
the architect and the engineers a provision which requires ownership of all architectural and engineering drawings to be transferred to Tenant upon the substantial completion of the Alteration and Tenant hereby grants to Landlord a non-exclusive right to use such drawings, including, without limitation, a right to make copies thereof. Tenant shall cause each architect/space planner and engineer retained by Tenant to follow Landlord’s
standard construction administration procedures and to utilize the standard specifications and details for the Building, all as reasonably promulgated by Landlord from time to time. Tenant and Tenant’s architect/space planner shall verify, in
the field, the dimensions and conditions as shown on the relevant portions of the “Base Building” plans, and Tenant and Tenant’s architect/space planner shall be solely responsible for the same, and Landlord shall have no
responsibility in connection therewith. In addition, at Landlord’s option, Landlord may submit Tenant’s plans, specifications and working drawings to a third-party architect and/or engineer, selected by Landlord, for their review, at
Tenant’s sole cost and expense. Landlord’s review of plans, specifications and

working drawings as set forth in this Section 8.2, shall be for its sole purpose and shall not imply Landlord’s review of the same, or obligate Landlord to review the same, for quality,
design, compliance with applicable building codes or other like matters. Accordingly, notwithstanding that any plans, specifications or working drawings are reviewed by Landlord or its space planner, architect, engineers and consultants, and
notwithstanding any advice or assistance which may be rendered to Tenant by Landlord or Landlord’s space planner, architect, engineers, and consultants, Landlord shall have no liability whatsoever in connection therewith and shall not be
responsible for any omissions or errors contained in the plans, specifications and working drawings for the Alterations, and Tenant’s waiver and indemnity set forth in Section 10.1 of this Lease, below, shall
specifically apply to the plans, specifications and working drawings for the Alterations. Following Landlord’s approval in its reasonable discretion of all plans, specifications and working drawings for the Alterations, a contractor to
construct the Alterations shall be selected by Tenant from the list of contractors approved by Landlord. In the event Tenant requests any Alterations in the Premises which require or give rise to governmentally required changes to the “Base
Building,” as that term is defined below, then Landlord shall, at Tenant’s expense, make such changes to the Base Building (provided that Landlord has notified Tenant of such necessity in writing and Tenant has consented to the same). As
used in this Lease, the “Base Building” shall include the structural portions of the Building, and the public restrooms, elevators, exit stairwells and the systems and equipment located in the internal core of the Building on the
floor or floors on which the Premises are located. The term “Base Building,” as used in this Lease, shall not be deemed to have the same meaning as the term “Base, Shell and Core,” as the same is defined in Section 1 of the
Tenant Work Letter. In performing the work of any Alterations for which Tenant is responsible, Tenant shall have the work performed in such manner so as not to obstruct access to the Project or any portion thereof, by any other tenant of the
Project, and so as not to unreasonably obstruct the business of Landlord or other tenants in the Project. Tenant shall not use (and upon notice from Landlord shall cease using) contractors, services, workmen, labor, materials or equipment that, in
Landlord’s reasonable judgment, would disturb labor harmony with the workforce or trades engaged in performing other work, labor or services in or about the Building or the Common Areas. In addition to Tenant’s obligations under
Article 9 of this Lease, upon completion of any Alterations, Tenant agrees to cause a Notice of Completion to be recorded in the office of the Recorder of the County in which the Project is located in accordance with Section 3093 of the
Civil Code of the State of California or any successor statute, and Tenant shall deliver to the Project construction manager a reproducible copy of the “as built” drawings of the Alterations in CAD format as well as all permits, approvals
and other documents issued by any governmental agency in connection with the Alterations. Notwithstanding anything set forth in this Article 8 to the contrary, construction of an Alteration shall not commence until
(a) the Alteration Contract has been fully executed and delivered to Landlord, and (b) Tenant has procured, and delivered to Landlord a copy of, all applicable permits. 

8.3    Payment for Improvements. Tenant shall (x) comply with Landlord’s requirements for final
lien releases and waivers in connection with Tenant’s payment for work to contractors, and (y) sign Landlord’s reasonable contractor’s rules and regulations. Tenant shall pay to Landlord upon receipt of written demand from
Landlord, an amount equal to the sum of (i) Landlord’s supervision fee for its involvement with the Alterations, which supervision fee shall be equal to five percent (5%) of the hard costs associated with the Alterations, and (ii) all

reasonable out of pockets incurred by Landlord related to the construction of the Alterations. Such supervision fee shall not apply to the Tenant Improvements, which shall be subject to any fees
set forth in the Tenant Work Letter. 
 8.4    Construction Insurance. In the event that any Alterations
are made pursuant to this Article 8, prior to the commencement of such Alterations, Tenant shall provide Landlord with certificates of insurance evidencing compliance with the requirements of Section 10.14 of this Lease, it
being understood and agreed that all of such Alterations shall be insured by Tenant pursuant to Article 10 of this Lease immediately upon completion thereof. In addition, Landlord may, in its discretion, require Tenant to obtain a lien and
completion bond or some alternate form of security satisfactory to Landlord in an amount sufficient to ensure the lien-free completion of such Alterations and naming Landlord as a co-obligee. 

8.5    Landlord’s Property. All Alterations, improvements, and/or fixtures
which may be installed in or about the Premises, from time to time, shall be at the sole cost of Tenant and shall be and become the property of Landlord; provided, however, Landlord may, by written notice to Tenant prior to the end of the Lease
Term, or given following any earlier termination of this Lease, require Tenant, at Tenant’s expense, to remove any Alterations or improvements and to repair any damage to the Premises and Building caused by such removal and return the affected
portion of the Premises to their condition existing prior to the installation of such Alterations or improvements; provided; however, that notwithstanding the foregoing, upon request by Tenant at the time of Tenant’s request for Landlord’s
consent to any Alteration or improvement, Landlord shall notify Tenant whether the applicable Alteration or improvement will be required to be removed pursuant to the terms of this Section 8.5. Notwithstanding the
foregoing, Tenant shall not be required to remove any Tenant Improvements or Alterations which are normal and customary business office improvements; provided, however, in any event Landlord may require Tenant to remove all (i) rolling files
and structural supports, (ii) built-in or high-density file systems, (iii) any supplemental HVAC system installed by Tenant, (iv) any structural improvements, and (v) any security or
information technology systems installed by or on behalf of Tenant in the Premises. If Tenant fails to complete such removal and/or to repair any damage caused by the removal of any Alterations or improvements in the Premises and return the affected
portion of the Premises to their condition existing prior to the installation of such Alterations or improvements prior to the expiration or earlier termination of this Lease, then Rent shall continue to accrue under this Lease in accordance with
Article 16, below, after the end of the Lease Term until such work shall be completed, and Landlord shall have the right, but not the obligation, to perform such work and to charge the cost thereof to Tenant. Tenant hereby
protects, defends, indemnifies and holds Landlord harmless from any liability, cost, obligation, expense or claim of lien, including but not limited to, court costs and reasonable attorneys’ fees, in any manner relating to the installation,
placement, removal or financing of any such Alterations, improvements, fixtures and/or equipment in, on or about the Premises, which obligations of Tenant shall survive the expiration or earlier termination of this Lease.

 ARTICLE 9 

COVENANT AGAINST LIENS 

Tenant shall keep the Project and Premises free from any liens or encumbrances arising out of the work performed, materials furnished or
obligations incurred by or on behalf of Tenant, and shall protect, defend, indemnify and hold Landlord harmless from and against any claims, liabilities, judgments or costs (including, without limitation, reasonable attorneys’ fees and costs)
arising out of same or in connection therewith. Tenant shall give Landlord notice at least twenty (20) days prior to the commencement of any work on the Premises which may give rise to a lien on the Premises or Building (or such additional time
as may be necessary under applicable laws) to afford Landlord the opportunity of posting and recording appropriate notices of non-responsibility. Tenant shall remove any such lien or encumbrance by bond or
otherwise within ten (10) days after notice by Landlord, and if Tenant shall fail to do so, Landlord may pay the amount necessary to remove such lien or encumbrance, without being responsible for investigating the validity thereof. The amount
so paid shall be deemed Additional Rent under this Lease payable upon demand, without limitation as to other remedies available to Landlord under this Lease. Nothing contained in this Lease shall authorize Tenant to do any act which shall subject
Landlord’s title to the Building or Premises to any liens or encumbrances whether claimed by operation of law or express or implied contract. Any claim to a lien or encumbrance upon the Building or Premises arising in connection with any such
work or respecting the Premises not performed by or at the request of Landlord shall be null and void, or at Landlord’s option shall attach only against Tenant’s interest in the Premises and shall in all respects be subordinate to
Landlord’s title to the Project, Building and Premises. 
 ARTICLE 10 

TENANT’S INDEMNITY AND INSURANCE 

10.1    Tenant’s Indemnity. 

10.1.1    Indemnity. To the maximum extent permitted by law, Tenant waives any right to contribution against
the “Landlord Parties,” as that term is defined in Section 10.13, below, and agrees to indemnify and save harmless the Landlord Parties from and against all claims of whatever nature in the case of (i),
(ii) and (iii) below arising from or claimed to have arisen from (i) the use or occupancy or manner of use or occupancy of the Premises by or acts within the Premises of the “Tenant Parties,” as that term is defined in
Section 10.13, below; (ii) any accident, injury or damage whatsoever caused to any person, or to the property of any person, occurring in or about the Premises from the earlier of (A) the date on which any Tenant
Party first enters the Premises to perform work or (B) the Lease Commencement Date, and thereafter throughout and until the end of the Lease Term and after the end of the Lease Term for as long as any of Tenant’s Property, as defined in
Section 10.4, remains on the Premises, or Tenant or anyone acting by, through or under Tenant may use, be in occupancy of any part of, or have access to the Premises or any portion thereof; (iii) any accident, injury or damage whatsoever
occurring outside the Premises but within the Project, where such accident, injury or damage results, or is claimed to have resulted, from any negligence or willful misconduct on the part of any of the Tenant Parties; or (iv) any breach
of this Lease by Tenant. Tenant shall pay

 SF
LEGAL/JH-MY










 
such indemnified amounts as they are incurred by the Landlord Parties. This indemnification shall not be construed to deny or reduce any other rights or obligations of indemnity that a Landlord
Party may have under this Lease or the common law. Notwithstanding anything contained herein to the contrary, Tenant shall not be obligated to indemnify a Landlord Party for any claims to the extent that such Landlord Party’s damages in
fact result from such Landlord Party’s gross negligence or willful misconduct. 
 10.1.2    Breach.
In the event that Tenant breaches any of its indemnity obligations hereunder or under any other contractual or common law indemnity, Tenant shall pay to the Landlord Parties all liabilities, loss, cost, or expense (including attorney’s
fees) incurred as a result of said breach, and the reasonable value of time expended by the Landlord Parties as a result of said breach. 

10.1.3    No limitation. The indemnification obligations under this Section shall not be limited in any way
by any limitation on the amount or type of damages, compensation or benefits payable by or for Tenant or any subtenant or other occupant of the Premises under workers’ compensation acts, disability benefit acts, or other employee benefit acts.
Tenant waives any immunity from or limitation on its indemnity or contribution liability to the Landlord Parties based upon such acts. 

10.1.4    Subtenants and other occupants. Tenant shall require its subtenants and other occupants of the
Premises to provide similar indemnities to the Landlord Parties in a form acceptable to Landlord. 

10.1.5    Survival. The terms of this section shall survive any termination or expiration of this Lease.

 10.1.6    Costs. The foregoing indemnity and hold harmless agreement shall include indemnity for all
costs, expenses and liabilities (including, without limitation, attorneys’ fees and disbursements) incurred by the Landlord Parties in connection with any such claim or any action or proceeding brought thereon, and the defense thereof.
In addition, in the event that any action or proceeding shall be brought against one or more Landlord Parties by reason of any such claim, Tenant, upon request from the Landlord Party, shall resist and defend such action or proceeding on behalf of
the Landlord Party by counsel appointed by Tenant’s insurer (if such claim is covered by insurance without reservation) or otherwise by counsel reasonably satisfactory to the Landlord Party. The Landlord Parties shall not be bound by any
compromise or settlement of any such claim, action or proceeding without the prior written consent of such Landlord Parties. 

10.2    Tenant’s Risk. Tenant agrees to use and occupy the Premises, and to use such other portions of
the Building and the Project as Tenant is given the right to use by this Lease at Tenant’s own risk. The Landlord Parties shall not be liable to the Tenant Parties for any damage, injury, loss, compensation, or claim (including, but not
limited to, claims for the interruption of or loss to a Tenant Party’s business) based on, arising out of or resulting from any cause whatsoever, including, but not limited to, repairs to any portion of the Premises or the Building or the
Project, any fire, robbery, theft, mysterious disappearance, or any other crime or casualty, the actions of any other tenants of the Building or of any other person or persons, or any leakage

in any part or portion of the Premises or the Building or the Project, or from water, rain or snow that may leak into, or flow from any part of the Premises or the Building or the Project, or
from drains, pipes or plumbing fixtures in the Building or the Project. Any goods, property or personal effects stored or placed in or about the Premises shall be at the sole risk of the Tenant Party, and neither the Landlord Parties
nor their insurers shall in any manner be held responsible therefor. The Landlord Parties shall not be responsible or liable to a Tenant Party, or to those claiming by, through or under a Tenant Party, for any loss or damage that may be
occasioned by or through the acts or omissions of persons occupying adjoining premises or any part of the premises adjacent to or connecting with the Premises or any part of the Building or otherwise. Notwithstanding the foregoing, the Landlord
Parties shall not be released from liability for any injury, loss, damages or liability to the extent arising from any gross negligence or willful misconduct of the Landlord Parties; provided, however, in no event shall the Landlord Parties have any
liability to a Tenant Party based on any loss with respect to or interruption in the operation of Tenant’s business. The provisions of this section shall be applicable until the expiration or earlier termination of the Lease Term,
and during such further period as any of Tenant’s Property remains on the Premises, or Tenant or any one acting by, through or under Tenant may use, be in occupancy of any part of, or have access to the Premises or of the Building. 

10.3    Tenant’s Commercial General Liability Insurance. Tenant agrees to maintain in full force on or
before the earlier of (i) the date on which any Tenant Party first enters the Premises for any reason or (ii) the Lease Commencement Date throughout the Lease Term of this Lease, and thereafter, so long as any of Tenant’s Property
remains on the Premises or Tenant or anyone acting by, through or under Tenant may use, be in occupancy of any part of, or have access to the Premises, a policy of commercial general liability insurance, on an occurrence basis, issued on a form at
least as broad as Insurance Services Office (“ISO”) Commercial General Liability Coverage “occurrence” form CG 00 01 10 01 or another ISO Commercial General Liability “occurrence” form providing equivalent coverage.
Such insurance shall include contractual liability coverage, specifically covering but not limited to the indemnification obligations undertaken by Tenant in this Lease. The minimum limits of liability of such insurance shall be $5,000,000.00 per
occurrence, which may be satisfied through a combination or primary and excess/umbrella insurance. In addition, in the event Tenant hosts a function in the Premises, Tenant agrees to obtain, and cause any persons or parties providing services for
such function to obtain, the appropriate insurance coverages as reasonably determined by Landlord (including liquor liability coverage, if applicable) and provide Landlord with evidence of the same. 

10.4    Tenant’s Property Insurance. Tenant shall maintain at all times during the Lease Term, and
during such earlier or later time as Tenant may be performing work in or to the Premises or have property, fixtures, furniture, equipment, machinery, goods, supplies, wares or merchandise on the Premises, and continuing thereafter so
long as any of Tenant’s Property remains on the Premises, or Tenant or anyone acting by, through or under Tenant may use, be in occupancy of or have access to, any part of the Premises, business interruption insurance and (insurance against
loss or damage covered by the so-called “all risk” type insurance coverage with respect to (i) Tenant’s property, fixtures, furniture, equipment, machinery, goods, supplies, wares and
merchandise, and other property of Tenant located at the Premises, (ii) the “Tenant

Improvements,” as that term is defined in the Tenant Work Letter, and any other improvements which exist in the Premises as of the Delivery Date (except as modified by the Tenant
Improvements and excluding the Base Building) (the “Original Improvements”), and all additions, alterations, and improvements and other modifications made by or on behalf of the Tenant in the Premises, (iii) any property of
third parties, including but not limited to leased or rented property, in the Premises in Tenant’s care, custody, use or control, provided that such insurance in the case of (iii) may be maintained by such third parties, and
(iv) other property of Tenant located at the Premises, (collectively “Tenant’s Property”). The business interruption insurance required by this section shall be in minimum amounts typically carried by prudent
tenants engaged in similar operations, but in no event shall be in an amount less than the Base Rent then in effect during any Lease Year, plus any Additional Rent due and payable for the immediately preceding Lease Year. The “all risk”
insurance required by this section shall be in an amount at least equal to the full replacement cost of Tenant’s Property. In addition, during such time as Tenant is performing work in or to the Premises, Tenant, at Tenant’s expense, shall
also maintain, or shall cause its contractor(s) to maintain, builder’s risk insurance for the full insurable value of such work. Landlord and such additional persons or entities as Landlord may reasonably request shall be named as loss payees,
as their interests may appear, on the policy or policies required by clause (ii) of this Section. In the event of loss or damage covered by the “all risk” insurance required by this section, the responsibilities for repairing or
restoring the loss or damage shall be determined in accordance with Article 11 of this Lease, below. To the extent that Landlord is obligated to pay for the repair or restoration of the loss or damage covered by the policy,
Landlord shall be paid the proceeds of the “all risk” insurance covering the loss or damage. To the extent Tenant is obligated to pay for the repair or restoration of the loss or damage, covered by the policy, Tenant shall be paid the
proceeds of the “all risk” insurance covering the loss or damage. If both Landlord and Tenant are obligated to pay for the repair or restoration of the loss or damage covered by the policy, the insurance proceeds shall be paid to each of
them in the pro rata proportion of their obligations to repair or restore the loss or damage. If the loss or damage is not repaired or restored (for example, if the Lease is terminated pursuant to Section 11.2 of this
Lease, below), the insurance proceeds shall be paid to Landlord and Tenant in the pro rata proportion of their relative contributions to the cost of the leasehold improvements covered by the policy. 

10.5    Tenant’s Other Insurance. Throughout the Lease Term, Tenant shall
obtain and maintain (1) comprehensive automobile liability insurance (covering any automobiles owned or operated by Tenant at the Project) issued on a form at least as broad as ISO Business Auto Coverage form CA 00 01 07 97 or other form
providing equivalent coverage; (2) worker’s compensation insurance or participation in a monopolistic state workers’ compensation fund; and (3) employer’s liability insurance or (in a monopolistic state) Stop Gap Liability
insurance. Such automobile liability insurance shall be in an amount not less than One Million Dollars ($1,000,000) for each accident. Such worker’s compensation insurance shall carry minimum limits as defined by the law of the jurisdiction in
which the Premises are located (as the same may be amended from time to time). Such employer’s liability insurance shall be in an amount not less than One Million Dollars ($1,000,000) for each accident, One Million Dollars ($1,000,000)
disease-policy limit, and One Million Dollars ($1,000,000) disease-each employee.

 10.6    Requirements For Insurance. All insurance required to
be maintained by Tenant pursuant to this Lease shall be maintained with responsible companies that are admitted to do business, and are in good standing, in the jurisdiction in which the Premises are located and that have a rating of at least
“A” and are within a financial size category of not less than “Class VIII” in the most current Best’s Key Rating Guide or such similar rating as may be reasonably selected by Landlord. All such insurance shall:
(1) be reasonably acceptable in form and content to Landlord; (2) be primary and noncontributory; and (3) if available under prevailing insurance policy cancellation provisions, contain an endorsement prohibiting cancellation, failure
to renew, reduction of amount of insurance, or change in coverage without the insurer first giving Landlord thirty (30) days’ prior written notice (by certified or registered mail, return receipt requested, or by fax or email) of such
proposed action, provided that if such endorsement is not reasonably available, Tenant shall immediately notify Landlord upon cancellation, failure to renew, reduction of amount of insurance, or change in coverage with respect to any such insurance.
No such policy shall contain any self-insured retention greater than $25,000.00. Any deductibles and such self-insured retentions shall be deemed to be “insurance” for purposes of the waiver in Section 10.13 of
this Lease, below. Landlord reserves the right from time to time to require Tenant to obtain higher minimum amounts of insurance based on such limits as are customarily carried with respect to similar properties in the area in which the Premises are
located. The minimum amounts of insurance required by this Lease shall not be reduced by the payment of claims or for any other reason. In the event Tenant shall fail to obtain or maintain any insurance meeting the requirements of this Article, or
to deliver such policies or certificates as required by this Article, Landlord may, at its option, on ten (10) days’ prior written notice to Tenant, procure such policies for the account of Tenant, and the cost thereof shall be paid to
Landlord within ten (10) business days after delivery to Tenant of bills therefor. 
 10.7    Additional
Insureds. The commercial general liability and auto insurance carried by Tenant pursuant to this Lease, and any additional liability insurance carried by Tenant pursuant to Section 10.3 of this Lease, above, shall
name Landlord, Landlord’s managing agent, and such other persons as Landlord may reasonably request from time to time as additional insureds (collectively “Additional Insureds”) with respect to liability arising out of or
related to this Lease or the operations of Tenant. Such insurance shall provide primary coverage without contribution from any other insurance carried by or for the benefit of Landlord, Landlord’s managing agent, or other Additional Insureds.

 10.8    Certificates Of Insurance. On or before the earlier of (i) the date on which any Tenant
Party first enters the Premises for any reason or (ii) the Lease Commencement Date, Tenant shall furnish Landlord with certificates evidencing the insurance coverage required by this Lease, and renewal certificates shall be furnished to
Landlord at least annually thereafter, and at least thirty (30) days prior to the expiration date of each policy for which a certificate was furnished. (Acceptable forms of such certificates for liability and property insurance, respectively,
are attached hereto as Exhibit G.) In jurisdictions requiring mandatory participation in a monopolistic state workers’ compensation fund, the insurance certificate requirements for the coverage
required for workers’ compensation will be satisfied by a letter from the appropriate state agency confirming participation in accordance with statutory requirements. Such current participation letters required by this Section shall be provided
every six (6) months for the duration of this Lease. Failure by the Tenant to provide the certificates or

letters required by this Section shall not be deemed to be a waiver of the requirements in this Section. Upon request by Landlord, a true and complete copy of any insurance policy required by
this Lease shall be delivered to Landlord within ten (10) days following Landlord’s request. 

10.9    Subtenants And Other Occupants. Tenant shall require its subtenants and other occupants of the
Premises to provide written documentation evidencing the obligation of such subtenant or other occupant to indemnify the Landlord Parties to the same extent that Tenant is required to indemnify the Landlord Parties pursuant to
Section 10.1 of this Lease, above, and to maintain insurance that meets the requirements of this Article, and otherwise to comply with the requirements of this Article, provided that the terms of this Section 10.9
shall not relieve Tenant of any of its obligations to comply with the requirements of this Article. Tenant shall require all such subtenants and occupants to supply certificates of insurance evidencing that the insurance requirements of this Article
have been met and shall forward such certificates to Landlord on or before the earlier of (i) the date on which the subtenant or other occupant or any of their respective direct or indirect partners, officers, shareholders, directors, members,
trustees, beneficiaries, servants, employees, principals, contractors, licensees, agents, invitees or representatives first enters the Premises or (ii) the commencement of the sublease. Tenant shall be responsible for identifying and remedying
any deficiencies in such certificates or policy provisions. 
 10.10    No Violation Of Building Policies.
Tenant shall not commit or permit any violation of the policies of fire, boiler, sprinkler, water damage or other insurance covering the Project and/or the fixtures, equipment and property therein carried by Landlord, or do or permit anything to be
done, or keep or permit anything to be kept, in the Premises, which in case of any of the foregoing (i) would result in termination of any such policies, (ii) would adversely affect Landlord’s right of recovery under any of such
policies, or (iii) would result in reputable and independent insurance companies refusing to insure the Project or the property of Landlord in amounts reasonably satisfactory to Landlord. 

10.11    Tenant To Pay Premium Increases. If, because of anything done, caused or permitted to be done, or
omitted by Tenant (or its subtenant or other occupants of the Premises), the rates for liability, fire, boiler, sprinkler, water damage or other insurance on the Project or on the property and equipment of Landlord or any other tenant or subtenant
in the Building shall be higher than they otherwise would be, Tenant shall reimburse Landlord and/or the other tenants and subtenants in the Building for the additional insurance premiums thereafter paid by Landlord or by any of the other tenants
and subtenants in the Building which shall have been charged because of the aforesaid reasons, such reimbursement to be made from time to time within thirty (30) days after Landlord’s demand. 

10.12    Landlord’s Insurance. 

10.12.1    Required insurance. Landlord shall maintain insurance against loss or damage with respect to the
Building on an “all risk” type insurance form, with customary exceptions, subject to such deductibles and self-insured retentions as Landlord may determine, in an amount equal to at least the full replacement value of the Building and the
Common Areas. The cost of such insurance shall be treated as a part of Operating Expenses. Such insurance shall be maintained with an insurance company selected by Landlord. Payment for losses thereunder shall be made solely to Landlord.

 10.12.2    Optional insurance. Landlord may maintain such
additional insurance with respect to the Building and the Project, including, without limitation, earthquake insurance, terrorism insurance, flood insurance, liability insurance and/or rent insurance, as Landlord may in its sole discretion elect.
Landlord may also maintain such other insurance as may from time to time be required by a “Mortgagee,” as that term is defined in Section 18.2 of this Lease, below. Subject to
Section 4.2.7, the cost of all such additional insurance shall also be part of the Operating Expenses. 

10.12.3    Blanket and self-insurance. Any or all of Landlord’s insurance may be provided by blanket
coverage maintained by Landlord or any affiliate of Landlord under its insurance program for its portfolio of properties, or by Landlord or any affiliate of Landlord under a program of self-insurance, and in such event, subject to
Section 4.2.7, Operating Expenses shall include the portion of the reasonable cost of blanket insurance or self-insurance that is allocated to the Building. 

10.12.4    No obligation. Landlord shall not be obligated to insure, and shall not assume any liability of
risk of loss for, Tenant’s Property, including any such property or work of tenant’s subtenants or occupants. Landlord will also have no obligation to carry insurance against, nor be responsible for, any loss suffered by Tenant, subtenants
or other occupants due to interruption of Tenant’s or any subtenant’s or occupant’s business. 

10.13    Waiver Of Subrogation. To the extent permitted by law, and notwithstanding any term or provision of
this Lease to the contrary, the parties hereto waive and release any and all rights of recovery against the other, and agree not to seek to recover from the other or to make any claim against the other, and in the case of Landlord, against all
Tenant Parties, and in the case of Tenant, against all Landlord Parties, for any loss or damage to property or injury to persons incurred by the waiving/releasing party to the extent such loss or damage is insured under any property or workers’
compensation insurance policy required by this Lease or which would have been so insured had the party carried the property or workers’ compensation insurance it was required to carry hereunder. Tenant shall obtain from its subtenants and other
occupants of the Premises a similar waiver and release of claims against any or all of Tenant Parties or Landlord Parties, and Landlord shall provide a similar waiver and release of claims against each such subtenant of the Premises or any portion
thereof. The insurance policies required by this Lease shall contain no provision that would invalidate or restrict the parties’ waiver and release of the rights of recovery in this section. The parties hereto covenant that no insurer shall
hold any right of subrogation against the parties hereto by virtue of such insurance policy. 
 The term “Landlord Party”
or “Landlord Parties” shall mean Landlord, any affiliate of Landlord, Landlord’s managing agents for the Building, each Mortgagee, each ground lessor, and each of their respective direct or indirect partners, officers,
shareholders, directors, members, trustees, beneficiaries, servants, employees, principals, contractors, licensees, agents or representatives. For the purposes of this Lease, the term “Tenant Party” or “Tenant
Parties” shall mean Tenant, any affiliate of Tenant, any permitted subtenant or any other permitted

occupant of the Premises, and each of their respective direct or indirect partners, officers, shareholders, directors, members, trustees, beneficiaries, servants, employees, principals,
contractors, licensees, agents, or representatives. 
 10.14    Tenant’s Work. During such times as
Tenant is performing work or having work or services performed in or to the Premises, Tenant shall require its contractors, and their subcontractors of all tiers, to obtain and maintain commercial general liability, automobile, workers compensation,
employer’s liability, builder’s risk, and equipment/property insurance in such amounts and on such terms as are customarily required of such contractors and subcontractors on similar projects. The amounts and terms of all such insurance
are subject to Landlord’s written approval, which approval shall not be unreasonably withheld. The commercial general liability and auto insurance carried by Tenant’s contractors and their subcontractors of all tiers pursuant to
this section shall name the Additional Insureds as additional insureds with respect to liability arising out of or related to their work or services. Such insurance shall provide primary coverage without contribution from any other insurance carried
by or for the benefit of Landlord, Landlord’s managing agent, or other Additional Insureds. Such insurance shall also waive any right of subrogation against each Additional Insured. Tenant shall obtain and submit to Landlord, prior to the
earlier of (i) the entry onto the Premises by such contractors or subcontractors or (ii) commencement of the work or services, certificates of insurance evidencing compliance with the requirements of this section. 

ARTICLE 11 
 DAMAGE
AND DESTRUCTION 
 11.1    Repair of Damage to Premises by Landlord. Tenant shall promptly notify
Landlord of any damage to the Premises resulting from fire or any other casualty. If the Premises or any Common Areas necessary to Tenant’s use of or access to the Premises shall be damaged by fire or other casualty, Landlord shall promptly and
diligently, subject to reasonable delays for insurance adjustment or other matters beyond Landlord’s reasonable control, and subject to all other terms of this Article 11, restore the Base Building and such Common
Areas. Such restoration shall be to substantially the same condition of the Base Building and the Common Areas prior to the casualty, except for modifications required by zoning and building codes and other laws or by the holder of a mortgage on the
Building or Project or any other modifications to the Common Areas deemed desirable by Landlord, provided that 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, upon notice (the “Landlord Repair Notice”) to Tenant from Landlord, Tenant shall assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under Tenant’s insurance
required under item (ii) of Section 10.4 of this Lease, and Landlord shall repair any injury or damage to the Tenant Improvements and the Original Improvements installed in the Premises and shall return such Tenant
Improvements and Original Improvements to their original condition; provided that if the cost of such repair by Landlord exceeds the amount of insurance proceeds received by Landlord from Tenant’s insurance carrier, as assigned by Tenant, the
cost of such repairs shall be paid by Tenant to Landlord prior to Landlord’s commencement of repair of the damage. In the event that Landlord does not deliver the Landlord Repair Notice within sixty (60) days following

the date the casualty becomes known to Landlord, Tenant shall, at its sole cost and expense, repair any injury or damage to the Tenant Improvements and the Original Improvements installed in the
Premises and shall return such Tenant Improvements and Original Improvements to their original condition. Whether or not Landlord delivers a Landlord Repair Notice, prior to the commencement of construction, Tenant shall submit to Landlord, for
Landlord’s review and approval, all plans, specifications and working drawings relating thereto. In the event Landlord delivers the Landlord Repair Notice, Landlord shall select the contractors to perform the improvement work. In the event
Tenant performs the work, Tenant shall select the contractors to perform the improvement work, subject to Landlord’s reasonable approval. 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, if such fire or other casualty shall have damaged the Premises or a portion thereof or Common Areas necessary to Tenant’s occupancy, then
Landlord shall allow Tenant a proportionate abatement of Rent during the time and to the extent and in the proportion that the Premises or such portion thereof are unfit for occupancy for the purposes permitted under this Lease, and are not occupied
by Tenant as a result thereof. 
 11.2    Landlord’s Option to Repair.
Notwithstanding the terms of Section 11.1 of this Lease, Landlord may elect not to rebuild and/or restore the Premises, Building and/or Project, and instead terminate this Lease, by notifying Tenant in writing of such
termination within sixty (60) days after the date of discovery of the damage, such notice to include a termination date giving Tenant sixty (60) days to vacate the Premises, but Landlord may so elect only if the Building or Project shall
be damaged by fire or other casualty or cause, whether or not the Premises are affected, and one or more of the following conditions is present: (i) in Landlord’s reasonable judgment, repairs cannot reasonably be completed within one
hundred eighty (180) days after the date of discovery of the damage (when such repairs are made without the payment of overtime or other premiums); (ii) the holder of any mortgage on the Building or Project or ground lessor with respect to
the Building or Project shall require that the insurance proceeds or any portion thereof be used to retire the mortgage debt, or shall terminate the ground lease, as the case may be; (iii) at least $1,000,000.00 of the damage is not fully
covered by Landlord’s insurance policies or that portion of the proceeds from Landlord’s insurance policies allocable to the Building or the Project, as the case may be, and would not have been so covered by the insurance that Landlord is
required to maintain under this Lease; (iv) Landlord decides to rebuild the Building or Common Areas so that they will be substantially different structurally or architecturally; (v) the damage occurs during the last twelve
(12) months of the Lease Term and Landlord terminates the leases of all similarly sized tenants in the Building; or (vi) any owner of any other portion of the Project, other than Landlord, does not intend to repair the damage to such
portion of the Project; provided, however, that if such fire or other casualty shall have damaged the Premises or a portion thereof or Common Areas necessary to Tenant’s occupancy and as a result of such damage the Premises are unfit for
occupancy, and provided that Landlord does not elect to terminate this Lease pursuant to Landlord’s termination right as provided above, and either (a) the repairs cannot, in the reasonable opinion of Landlord’s contractor, be
completed within the lesser of two hundred seventy (270) days after being commenced and one (1) year after the date of damage, or (b) the damage occurs during the last twelve months of the Lease Term and will reasonably require in
excess of ninety (90) days to repair, Tenant may elect, no earlier than thirty (30) days after the date of the damage and not later than ninety (90) days

after the date of such damage, to terminate this Lease by written notice to Landlord effective as of the date specified in the notice, which date shall not be less than thirty (30) days nor
more than sixty (60) days after the date such notice is given by Tenant. 
 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
the Project, and any statute or regulation of the State of California, including, without limitation, Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or obligations concerning damage or destruction in the
absence of an express agreement between the parties, and any other statute or regulation, now or hereafter in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises, the Building or the
Project. 
 ARTICLE 12 

NONWAIVER 
 No
provision of this Lease shall be deemed waived by either party hereto unless expressly waived in a writing signed thereby. The waiver by either party hereto of any breach of any term, covenant or condition herein contained shall not be deemed to be
a waiver of any subsequent breach of same or any other term, covenant or condition herein contained. The subsequent acceptance of Rent hereunder by Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of any term, covenant
or condition of this Lease, other than the failure of Tenant to pay the particular Rent so accepted, regardless of Landlord’s knowledge of such preceding breach at the time of acceptance of such Rent. No acceptance of a lesser amount than the
Rent herein stipulated shall be deemed a waiver of Landlord’s right to receive the full amount due, nor shall any endorsement or statement on any check or payment or any letter accompanying such check or payment be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the full amount due. No receipt of monies by Landlord from Tenant after the termination of this Lease shall in any way alter the length
of the Lease Term or of Tenant’s right of possession hereunder, or after the giving of any notice shall reinstate, continue or extend the Lease Term or affect any notice given Tenant prior to the receipt of such monies, it being agreed that
after the service of notice or the commencement of a suit, or after final judgment for possession of the Premises, Landlord may receive and collect any Rent due, and the payment of said Rent shall not waive or affect said notice, suit or judgment.
No payment of Rent by Tenant after a breach by Landlord shall be deemed a waiver of any breach by Landlord. 
 ARTICLE 13 

CONDEMNATION 
 If
the whole or any material, as determined by Landlord in its reasonable discretion, part of the Premises, Building or Project shall be taken by power of eminent domain or condemned by any competent authority for any public or quasi-public use or
purpose, or if any adjacent property or street shall be so taken or condemned, or reconfigured or vacated by such authority

in such manner as to require the use, reconstruction or remodeling of any material part of the Premises, Building or Project, or if Landlord shall grant a deed or other instrument in lieu of such
taking by eminent domain or condemnation, Landlord shall have the option to terminate this Lease effective as of the date possession is required to be surrendered to the authority. If more than twenty-five percent (25%) of the rentable square feet
of the Premises is taken, or if all reasonable access to the Premises is substantially impaired, in each case for a period in excess of one hundred eighty (180) days, Tenant shall have the option to terminate this Lease effective as of the date
possession is required to be surrendered to the authority. Tenant shall not because of such taking assert any claim against Landlord or the authority for any compensation because of such taking and Landlord shall be entitled to the entire award or
payment in connection therewith, except that Tenant shall have the right to file any separate claim available to Tenant for any taking of Tenant’s personal property and fixtures belonging to Tenant and removable by Tenant upon expiration of the
Lease Term pursuant to the terms of this Lease, and for moving expenses, so long as such claims do not diminish the award available to Landlord, its ground lessor with respect to the Building or Project or its mortgagee, and such claim is payable
separately to Tenant. All Rent shall be apportioned as of the date of such termination. If any part of the Premises shall be taken, and this Lease shall not be so terminated, the Rent shall be proportionately abated. Tenant hereby waives any and all
rights it might otherwise have pursuant to Section 1265.130 of the California Code of Civil Procedure. Notwithstanding anything to the contrary contained in this Article 13, in the event of a temporary taking of all or any portion of the
Premises for a period of one hundred eighty (180) days or less, then this Lease shall not terminate but the Base Rent and the Additional Rent shall be abated for the period of such taking in proportion to the ratio that the amount of rentable
square feet of the Premises taken bears to the total rentable square feet of the Premises. Landlord shall be entitled to receive the entire award made in connection with any such temporary taking. 

ARTICLE 14 

ASSIGNMENT AND SUBLETTING 

14.1    Transfers. Tenant shall not, without the prior written consent of Landlord, assign, mortgage,
pledge, hypothecate, encumber, or permit any lien to attach to, or otherwise transfer, this Lease or any interest hereunder, permit any assignment, or other transfer of this Lease or any interest hereunder by operation of law, sublet the Premises or
any part thereof, or enter into any license or concession agreements or otherwise permit the occupancy or use of the Premises or any part thereof by any persons other than Tenant and its employees and contractors (all of the foregoing are
hereinafter sometimes referred to individually as a “Transfer,” and, collectively, as “Transfers” and any person to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a
“Transferee”). If Tenant desires Landlord’s consent to any Transfer, Tenant shall notify Landlord in writing, which notice (the “Transfer Notice”) shall include (i) the proposed effective date of the
Transfer, which shall not be less than thirty (30) days nor more than one hundred eighty (180) days after the date of delivery of the Transfer Notice, (ii) a description of the portion of the Premises to be transferred (the
“Subject Space”), (iii) all of the terms of the proposed Transfer and the consideration therefor, including calculation of the “Transfer Premium”, as that term is defined in Section 14.3
below, in connection with such Transfer, the name and address of the proposed Transferee, and a copy of

all existing executed and/or proposed documentation pertaining to the proposed Transfer, including all existing operative documents to be executed to evidence such Transfer or the agreements
incidental or related to such Transfer, (iv) current financial statements of the proposed Transferee certified by an officer, partner or owner thereof and any other information reasonably required by Landlord which will enable Landlord to
determine the financial responsibility, character, and reputation of the proposed Transferee, nature of such Transferee’s business and proposed use of the Subject Space, and (v) an executed estoppel certificate from Tenant in the form
attached hereto as Exhibit E. Any Transfer made without Landlord’s prior written consent shall, at Landlord’s option, be null, void and of no effect, and shall, at Landlord’s option,
constitute a default by Tenant under this Lease. Whether or not Landlord consents to any proposed Transfer, Tenant shall pay Landlord’s review and processing fees, as well as any reasonable professional fees (including, without limitation,
attorneys’, accountants’, architects’, engineers’ and consultants’ fees) incurred by Landlord, not to exceed $2,500 for a Transfer in the ordinary course of business, 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. Within thirty (30) days after receipt of any Transfer Notice, Landlord shall notify Tenant of Landlord’s decision to either grant or
withhold its consent to any such proposed Transfer. Without limitation as to other reasonable grounds for withholding consent, the parties hereby agree that it shall be reasonable under this Lease and under any applicable law for Landlord to
withhold consent to any proposed Transfer where one or more of the following apply: 
 14.2.1    The Transferee is of a
character or reputation or engaged in a business which is not consistent with the quality of the Building or the Project; 

14.2.2    The Transferee intends to use the Subject Space for purposes which are not permitted under this Lease; 

14.2.3    The Transferee is either a governmental agency or instrumentality thereof; 

14.2.4    The Transferee is not a party of reasonable financial worth and/or financial stability in light of the
responsibilities to be undertaken in connection with the Transfer on the date consent is requested; 
 14.2.5    The
proposed Transfer would cause a violation of another lease for space in the Project, or would give an occupant of the Project a right to cancel its lease; 

14.2.6    Either the proposed Transferee, or any person or entity which directly or indirectly, controls, is controlled

judgment, the use of the Premises by the proposed Transferee would not be comparable to the types of office use by other tenants in the

Project, would entail any alterations which would lessen the value of the tenant improvements in the Premises, would result in more than a reasonable density of occupants per square foot of the
Premises, would increase the burden on elevators or other Building systems or equipment over the burden thereon prior to the proposed Transfer, or would require increased services by Landlord; 

14.2.8    Intentionally omitted; 

14.2.9    The proposed Transfer would result in the existence of, in the aggregate, more than two (2) subtenants
occupying the Premises at any given time during the Lease Term; or 
 14.2.10    Any part of the rent payable under the
proposed Transfer shall be based in whole or in part on the income or profits derived from the Subject Space or if any proposed Transfer shall potentially have any adverse effect on the real estate investment trust qualification requirements
applicable to Landlord and its affiliates. 
 If Landlord consents to any Transfer pursuant to the terms of this
Section 14.2 (and does not exercise any recapture rights Landlord may have under Section 14.4 of this Lease), Tenant may within six (6) months after Landlord’s consent, but not later than
the expiration of said six-month period, enter into such Transfer of the Premises or portion thereof, upon substantially the same terms and conditions as are set forth in the Transfer Notice furnished by
Tenant to Landlord pursuant to Section 14.1 of this Lease, provided that if there are any changes in the terms and conditions from those specified in the Transfer Notice (i) such that Landlord would initially have been
entitled to refuse its consent to such Transfer under this Section 14.2, or (ii) which would cause the proposed Transfer to be materially more favorable to the Transferee than the terms set forth in Tenant’s
original Transfer Notice, Tenant shall again submit the Transfer to Landlord for its approval and other action under this Article 14 (including Landlord’s right of recapture, if any, under
Section 14.4 of this Lease). Notwithstanding anything to the contrary in this Lease, if Tenant or any proposed Transferee claims that Landlord has unreasonably withheld or delayed its consent under
Section 14.2 or otherwise has breached or acted unreasonably under this Article 14, their sole remedies shall be a suit for contract damages (other than damages for injury to, or interference with,
Tenant’s business, including, without limitation, loss of profits, however occurring) or a declaratory judgment and an injunction for the relief sought, and Tenant hereby waives the provisions of Section 1995.310 of the California Civil
Code, or any successor statute, and all other remedies, including, without limitation, any right at law or equity to terminate this Lease, on its own behalf and, to the extent permitted under all applicable laws, on behalf of the proposed
Transferee. Tenant shall indemnify, defend and hold harmless Landlord from any and all liability, losses, claims, damages, costs, expenses, causes of action and proceedings involving any third party or parties (including without limitation
Tenant’s proposed subtenant or assignee) who claim they were damaged by Landlord’s wrongful withholding or conditioning of Landlord’s consent; provided, however, Tenant shall not be obligated to indemnify Landlord for any such claims
to the extent that such damages in fact result from Landlord’s wrongful withholding or conditioning of Landlord’s consent.

 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 one hundred percent (100%) of any “Transfer Premium,” as that term is defined in this Section 14.3, received by
Tenant from such Transferee. “Transfer Premium” shall mean all rent, additional rent or other consideration payable by such Transferee in connection with the Transfer in excess of the Rent and Additional Rent payable by Tenant under
this Lease during the term of the Transfer on a per rentable square foot basis if less than all of the Premises is transferred, after deducting the reasonable expenses incurred by Tenant for (i) any changes, alterations and improvements to the
Premises in connection with the Transfer, (ii) any free base rent reasonably provided to the Transferee in connection with the Transfer (provided that such free rent shall be deducted only to the extent the same is included in the calculation
of total consideration payable by such Transferee), and (iii) any brokerage commissions in connection with the Transfer and (iv) legal fees reasonably incurred in connection with the Transfer (collectively, “Tenant’s
Subleasing Costs”). “Transfer Premium” shall also include, but not be limited to, key money, bonus money or other cash consideration paid by Transferee to Tenant in connection with such Transfer, and any payment in excess of fair
market value for services rendered by Tenant to Transferee or for assets, fixtures, inventory, equipment, or furniture transferred by Tenant to Transferee in connection with such Transfer. Landlord shall make a reasonable determination of the amount
of Landlord’s applicable share of the Transfer Premium on a monthly basis as rent or other consideration is paid by Transferee to Tenant under the Transfer. For purposes of calculating the Transfer Premium on a monthly basis, Tenant’s
Subleasing Costs shall be deemed to be expended by Tenant in equal monthly amounts over the entire term of the Transfer. 

14.4    Landlord’s Option as to Subject Space. Notwithstanding anything to
the contrary contained in this Article 14, in the event Tenant contemplates a Transfer of all or a portion of the Premises (or in the event of any other Transfer or Transfers entered into by Tenant as a subterfuge in order to avoid the terms
of this Section 14.4), Tenant shall give Landlord notice (the “Intention to Transfer Notice”) of such contemplated Transfer (whether or not the contemplated Transferee or the terms of such contemplated
Transfer have been determined); provided, however, that Landlord hereby acknowledges and agrees that Tenant shall have no obligation to deliver an Intention to Transfer Notice hereunder, and Landlord shall have no right to recapture space with
respect to an assignment or sublease pursuant to the terms of Section 14.8, below. The Intention to Transfer Notice shall specify the portion of and amount of rentable square feet of the Premises which Tenant intends to Transfer (the
“Contemplated Transfer Space”), the contemplated date of commencement of the Contemplated Transfer (the “Contemplated Effective Date”), and the contemplated length of the term of such contemplated Transfer, and
shall specify that such Intention to Transfer Notice is delivered to Landlord pursuant to this Section 14.4 in order to allow Landlord to elect to recapture the Contemplated Transfer Space for the term set forth in the
Intention to Transfer Notice. Thereafter, Landlord shall have the option, by giving written notice to Tenant within thirty (30) days after receipt of any Intention to Transfer Notice, to recapture the Contemplated Transfer Space. Such recapture
shall cancel and terminate (or suspend if not for the remainder of the Lease Term) this Lease with respect to such Contemplated Transfer Space as of the Contemplated Effective Date. In the event of a recapture by Landlord, if this Lease shall be
canceled with respect to less than the entire Premises, then Landlord shall be solely responsible, at Landlord’s sole cost, for demising the Contemplated Transfer Space from the remainder of the Premises, the Rent reserved herein

shall be prorated on the basis of the number of rentable square feet retained by Tenant in proportion to the number of rentable square feet contained in the Premises, and this Lease as so amended
shall continue thereafter in full force and effect, and upon request of either party, the parties shall execute written confirmation of the same. In connection with the construction of the demising wall, Landlord shall use commercially reasonable
efforts to minimize any material interference with Tenant’s access to and use of the Premises. If Landlord declines, or fails to elect in a timely manner, to recapture such Contemplated Transfer Space under this
Section 14.4, then, subject to the other terms of this Article 14, for a period of nine (9) months (the “Nine Month Period”) commencing on the last day of such thirty (30) day period,
Landlord shall not have any right to recapture the Contemplated Transfer Space with respect to any Transfer made during the Nine Month Period, provided that any such Transfer is substantially on the terms set forth in the Intention to Transfer
Notice, and provided further that any such Transfer shall be subject to the remaining terms of this Article 14. If such a Transfer is not so consummated within the Nine Month Period (or if a Transfer is so consummated, then upon the
expiration of the term of any Transfer of such Contemplated Transfer Space consummated within such Nine Month Period), Tenant shall again be required to submit a new Intention to Transfer Notice to Landlord with respect any contemplated Transfer, as
provided above in this Section 14.4. 
 14.5    Effect of Transfer. If Landlord
consents to a Transfer, then (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, including, without limitation, at Landlord’s option, a “Transfer Agreement,” as that
term is defined in this Section 14.5, below; (iv) Tenant shall furnish upon Landlord’s request a complete statement, certified by an independent certified public accountant, or Tenant’s chief financial
officer, setting forth in detail the computation of any Transfer Premium Tenant has derived and shall derive from such Transfer; and (v) no Transfer relating to this Lease or agreement entered into with respect thereto, whether with or without
Landlord’s consent, shall relieve Tenant or any guarantor of the Lease from any liability under this Lease, including, without limitation, in connection with the Subject Space, and, in the event of a Transfer of Tenant’s entire interest in
this Lease, the liability of Tenant and such Transferee shall be joint and several. Landlord or its authorized representatives shall have the right at all reasonable times to audit the books, records and papers of Tenant relating to any Transfer,
and shall have the right to make copies thereof. If the Transfer Premium respecting any Transfer shall be found understated, Tenant shall, within thirty (30) days after demand, pay the deficiency, and if understated by more than five percent
(5%), Tenant shall pay Landlord’s costs of such audit. Notwithstanding anything to the contrary contained in this Article 14, Landlord, at its option in its sole and absolute discretion, may require, as a condition to
the validity of any Transfer, that both Tenant and such Transferee enter into a separate written agreement directly with Landlord (a “Transfer Agreement”), which Transfer Agreement, among other things, shall create privity of
contract between Landlord and such Transferee with respect to the provisions of this Article 14, and shall contain such terms and provisions as Landlord may reasonably require, including, without limitation, the following: (A) such
Transferee’s agreement to be bound by all the obligations of Tenant under this Lease that accrue after the effective date of such Transfer, provided that, in the event of a Transfer of less than the entire Premises, the obligations to which
such Transferee shall agree to be so bound shall apply

only with respect to the Subject Space during the term of such Transfer; (B) such Transferee’s acknowledgment of, and agreement that such Transfer shall be subordinate and subject to,
Landlord’s rights under Section 19.3 of this Lease; and (C) Tenant’s and such Transferee’s recognition of and agreement to be bound by all the terms and provisions of this
Article 14, including, but not limited to, any such terms and provisions which Landlord, at its option, requires to be expressly set forth in such Transfer Agreement. 

14.6    Occurrence of Default. Any Transfer hereunder, whether or not such Transferee shall have executed a
Transfer Agreement, shall be subordinate and subject to the provisions of this Lease, and if this Lease shall be terminated during the term of any Transfer, then Landlord shall have all of the rights set forth in
Section 19.3 of this Lease with respect to such Transfer. In addition, if Tenant shall be in default under this Lease (beyond any applicable notice or cure period), then Landlord is hereby irrevocably authorized to direct
any Transferee to make all payments under or in connection with a Transfer directly to Landlord (which payments Landlord shall apply towards Tenant’s obligations under this Lease) until such default is cured. Such Transferee shall rely on any
representation by Landlord that Tenant is in default hereunder, without any need for confirmation thereof by Tenant. Upon any assignment, the assignee shall assume in writing all obligations and covenants of Tenant thereafter to be performed or
observed under this Lease. No collection or acceptance of rent by Landlord from any Transferee shall be deemed a waiver of any provision of this Article 14 or the approval of any Transferee or a release of Tenant from any
obligation under this Lease, whether theretofore or thereafter accruing. In no event shall Landlord’s enforcement of any provision of this Lease against any Transferee be deemed a waiver of Landlord’s right to enforce any term of this
Lease against Tenant or any other person. If Tenant’s obligations hereunder have been guaranteed, Landlord’s consent to any Transfer shall not be effective unless the guarantor also consents to such Transfer. 

14.7    Additional Transfers. For purposes of this Lease, the term “Transfer” shall also include
(i) if Tenant is a partnership or a limited liability company, the withdrawal or change, voluntary, involuntary or by operation of law, of more than fifty percent (50%) of the partners, officers or members, as applicable, or transfer of more
than fifty percent (50%) of partnership, ownership or membership interests (as applicable), within a twelve (12)-month period, or the dissolution of the partnership or limited liability company without immediate reconstitution thereof, and
(ii) if Tenant is a closely held corporation (i.e., whose stock is not publicly held and not traded through an exchange or over the counter), (A) the dissolution, merger, consolidation or other reorganization of Tenant or (B) the
sale or other transfer of an aggregate of more than fifty percent (50%) of the voting shares of Tenant (other than to immediate family members by reason of gift or death), within a twelve (12) month period. 

14.8    Non-Transfers. Notwithstanding anything to the contrary
contained in this Lease, (A) an assignment or subletting of all or a portion of the Premises to an affiliate of Tenant (an entity which is controlled by, controls, or is under common control with, Tenant), (B) a sale or issuance of corporate
shares of capital stock in Tenant in connection with a public offering of Tenant’s stock on a nationally-recognized stock exchange, (C) an assignment of the Lease to an entity which acquires all or substantially all of the stock or assets
of Tenant, or (D) an assignment of the Lease to an entity which is the resulting entity of a merger or consolidation of Tenant during the Lease Term, shall not be deemed a Transfer under Article 14 of this Lease

(any such assignee or sublessee described in items (A) through (D) of this Section 14.8 hereinafter referred to as a “Permitted Non-Transferee”), provided that (i) Tenant notifies Landlord at least thirty (30) days prior to the effective date of any such assignment or sublease and promptly supplies Landlord with any
documents or information reasonably requested by Landlord regarding such transfer or transferee as set forth above, (ii) Tenant is not in default, beyond any applicable notice and cure period, and such assignment or sublease is not a subterfuge
by Tenant to avoid its obligations under this Lease, (iii) any Non-Transferee Assignee shall have a tangible net worth (not including goodwill as an asset) computed in accordance with generally accepted
accounting principles (“Net Worth”) at least equal to the greater of (1) the Net Worth of Original Tenant on the date of this Lease, and (2) the Net Worth of Tenant on the day immediately preceding the effective date of
such assignment or sublease (only if it is a sublease of more than fifty percent (50%) of the Premises), and (iv) no assignment relating to this Lease, whether with or without Landlord’s consent, shall relieve Tenant from any liability
under this Lease, and, in the event of an assignment of Tenant’s entire interest in this Lease, the liability of Tenant and such transferee shall be joint and several. An assignee of Tenant’s entire interest in this Lease who qualifies as
a Permitted Non-Transferee may also be referred to herein as a “Non-Transferee Assignee.” “Control,” as used in this
Section 14.8, shall mean the ownership, directly or indirectly, of at least fifty-one percent (51%) of the voting securities of, or possession of the right to vote, in the ordinary
direction of its affairs, of at least fifty-one percent (51%) of the voting interest in, any person or entity. 

ARTICLE 15 

SURRENDER OF PREMISES; OWNERSHIP AND 

REMOVAL OF TRADE FIXTURES 

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

15.2    Removal of Tenant Property by Tenant. Upon the expiration of the Lease Term, or upon any earlier
termination of this Lease, Tenant shall, subject to the provisions of this Article 15, quit and surrender possession of the Premises to Landlord in as good order and condition as when Tenant took possession and as
thereafter improved by Landlord and/or Tenant, reasonable wear and tear and repairs which are specifically made the responsibility of Landlord hereunder excepted and damage by casualty or condemnation to be governed by Article 11 and
Article 13, respectively. Upon such expiration or termination, Tenant shall, without expense to Landlord, remove or cause to be removed from the Premises all debris and

rubbish, such items of furniture, equipment, business and trade fixtures, free-standing cabinet work, movable partitions and other articles of personal property owned by Tenant or installed or
placed by Tenant at its expense in the Premises, and such similar articles of any other persons claiming under Tenant, as Landlord may, in its sole discretion, require to be removed, and Tenant shall repair at its own expense all damage to the
Premises and Building resulting from such removal. 
 ARTICLE 16 

HOLDING OVER 
 If
Tenant holds over after the expiration of the Lease Term or earlier termination thereof, with the express or implied consent of Landlord, such tenancy shall be from
month-to-month only, and shall not constitute a renewal hereof or an extension for any further term, and in such case Rent shall be payable at a monthly rate equal to
(i) one hundred fifty percent (150%) of the Rent applicable during the last rental period of the Lease Term under this Lease during the first month of such holdover and (ii) two hundred percent (200%) of the Rent applicable during the last
rental period of the Lease Term under this Lease thereafter. Such month-to-month tenancy shall be subject to every other applicable term, covenant and agreement
contained herein. Nothing contained in this Article 16 shall be construed as consent by Landlord to any holding over by Tenant, and Landlord expressly reserves the right to require Tenant to surrender possession of the
Premises to Landlord as provided in this Lease upon the expiration or other termination of this Lease. The provisions of this Article 16 shall not be deemed to limit or constitute a waiver of any other rights or remedies of
Landlord provided herein or at law. If Tenant fails to surrender the Premises upon the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold
Landlord harmless from all loss, costs (including reasonable attorneys’ fees) and liability resulting from such failure, including, without limiting the generality of the foregoing, any claims made by any succeeding tenant founded upon such
failure to surrender and any lost profits to Landlord resulting therefrom. 
 ARTICLE 17 

ESTOPPEL CERTIFICATES 

Within ten (10) business days following a request in writing by Landlord, Tenant shall execute, acknowledge and deliver to Landlord an
estoppel certificate, which, as submitted by Landlord, shall be substantially in the form of Exhibit E, attached hereto (or such other form as may reasonably be required by any prospective mortgagee or
purchaser of the Project, or any portion thereof), indicating therein any exceptions thereto that may exist at that time, and shall also contain any other information reasonably requested by Landlord or Landlord’s mortgagee or prospective
mortgagee. Any such certificate may be relied upon by any prospective mortgagee or purchaser of all or any portion of the Project. Tenant shall execute and deliver whatever other instruments may be reasonably required for such purposes. At any time
during the Lease Term, Landlord may require Tenant to provide Landlord with a current financial statement and financial statements of the two (2) years prior to the current financial statement year, provided Landlord executes a commercially
reasonable confidentiality or nondisclosure agreement

relating to such financial statements. Such statements shall be prepared in accordance with generally accepted accounting principles and, if such is the normal practice of Tenant, shall be
audited by an independent certified public accountant. Failure of Tenant to timely execute, acknowledge and deliver such estoppel certificate or other instruments shall constitute an acceptance of the Premises and an acknowledgment by Tenant that
statements included in the estoppel certificate are true and correct, without exception. Notwithstanding the foregoing, for so long as the capital stock of Tenant is traded publicly on a nationally-recognized stock exchange, the requirement for
Tenant to provide financial statements pursuant to the provisions of this Article 17 is inapplicable. 
 ARTICLE 18 

MORTGAGE OR GROUND LEASE 

18.1    Subordination. This Lease shall be subject and subordinate to all present and future ground or
underlying leases of the Building or Project and to the lien of any mortgage, trust deed or other encumbrances now or hereafter in force against the Building or Project or any part thereof, if any, and to all renewals, extensions, modifications,
consolidations and replacements thereof, and to all advances made or hereafter to be made upon the security of such mortgages or trust deeds, unless the holders of such mortgages, trust deeds or other encumbrances, or the lessors under such ground
lease or underlying leases, require in writing that this Lease be superior thereto (collectively, the “Superior Holders”); provided, however, that in consideration of and a condition precedent to Tenant’s agreement to
subordinate this Lease, shall be the receipt by Tenant of a subordination non-disturbance and attornment agreement in the commercially reasonable form provided by such Superior Holders, which requires such
Superior Holder to accept this lease, and not to disturb tenant’s possession, so long as an event of default has not occurred and be continuing (a “SNDAA”) executed by Landlord and the appropriate Superior Holder. Tenant
covenants and agrees in the event any proceedings are brought for the foreclosure of any such mortgage or deed in lieu thereof (or if any ground lease is terminated), to attorn, without any deductions or
set-offs whatsoever (except as expressly provided in this Lease), to the lienholder or purchaser or any successors thereto upon any such foreclosure sale or deed in lieu thereof (or to the ground lessor), if
so requested to do so by such purchaser or lienholder or ground lessor, and to recognize such purchaser or lienholder or ground lessor as the lessor under this Lease, provided such lienholder or purchaser or ground lessor shall agree to accept this
Lease and not disturb Tenant’s occupancy, so long as Tenant timely pays the rent and observes and performs the terms, covenants and conditions of this Lease to be observed and performed by Tenant. Landlord’s interest herein may be assigned
as security at any time to any lienholder. Tenant shall, within ten (10) business days of request by Landlord, execute such further commercially reasonable instruments 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. 

18.2    Notice to Lienholder or Ground Lessor. Notwithstanding anything to the contrary contained in
Article 28, below, or elsewhere in this Lease, upon receipt by Tenant of notice from any holder of a mortgage, trust deed or other encumbrance in force against the Building or the Project or any part thereof which includes
the Premises or any lessor under a

ground lease or underlying lease of the Building or the Project, or from Landlord, which notice sets forth the address of such lienholder or ground lessor, no notice of default from Tenant to
Landlord shall be effective unless and until a copy of the same is given to such lienholder or ground lessor at the appropriate address therefor (as specified in the above-described notice or at such other places as may be designated from time to
time in a notice to Tenant in accordance with Article 28, below), and the curing of any of Landlord’s defaults by such lienholder or ground lessor within a reasonable period of time after such notice from Tenant
(including a reasonable period of time to obtain possession or control of the Building or the Project, as the case may be, if such lienholder or ground lessor elects to do so) shall be treated as performance by Landlord. For the purposes of this
Article 18, the term “mortgage” shall include a mortgage on a leasehold interest of Landlord (but not a mortgage on Tenant’s leasehold interest hereunder). 

18.3    Assignment of Rents. With reference to any assignment by Landlord of Landlord’s interest in
this Lease, or the Rent payable to Landlord hereunder, conditional in nature or otherwise, which assignment is made to any holder of a mortgage, trust deed or other encumbrance in force against the Building or the Project or any part thereof which
includes the Premises or to any lessor under a ground lease or underlying lease of the Building or the Project, Tenant agrees as follows: 

18.3.1    The execution of any such assignment by Landlord, and the acceptance thereof by such lienholder or ground
lessor, shall never be treated as an assumption by such lienholder or ground lessor of any of the obligations of Landlord under this Lease, unless such lienholder or ground lessor shall, by notice to Tenant, specifically otherwise elect. 

18.3.2    Notwithstanding delivery to Tenant of the notice required by Section 18.3.1, above, such lienholder or
ground lessor, respectively, shall be treated as having assumed Landlord’s obligations under this Lease only upon such lienholder’s foreclosure of any such mortgage, trust deed or other encumbrance, or acceptance of a deed in lieu thereof,
and taking of possession of the Building or the Project or applicable portion thereof, or such ground lessor’s termination of any such ground lease or underlying leases and assumption of Landlord’s position hereunder, as the case may be.
In no event shall such lienholder, ground lessor or any other successor to Landlord’s interest in this Lease, as the case may be, be liable for any security deposit paid by Tenant to Landlord, unless and until such lienholder, ground lessor or
other such successor, respectively, actually has been credited with or has received for its own account as landlord the amount of such security deposit or any portion thereof (in which event the liability of such lienholder, ground lessor or other
such successor, as the case may be, shall be limited to the amount actually credited or received). 
 18.3.3    In no
event shall the acquisition of title to the Building and the land upon which the Building is located or the Project or any part thereof which includes the Premises by a purchaser which, simultaneously therewith, leases back to the seller thereof the
entire Building or the land upon which the Building is located or the Project or the entirety of that part thereof acquired by such purchaser, as the case may be, be treated as an assumption, by operation of law or otherwise, of Landlord’s
obligations under this Lease, but Tenant shall look solely to such seller-lessee, or to the successors to or assigns of such seller-lessee’s estate, for performance of Landlord’s obligations under this Lease. In any such event, this Lease
shall be subject and

subordinate to the lease to such seller-lessee, and Tenant covenants and agrees in the event the lease to such seller-lessee is terminated to attorn, without any deductions or set-offs whatsoever (except as expressly provided in this Lease), to such purchaser-lessor, if so requested to do so by such purchaser-lessor, and to recognize such purchaser-lessor as the lessor under this Lease,
provided that in consideration of and a condition precedent to Tenant’s agreement to subordinate this Lease, shall be the receipt by Tenant of a SNDAA which requires such purchaser-lessor not to disturb Tenant’s possession, so long as an
event of default has not occurred and be continuing executed by Landlord and the purchaser-lessor. For all purposes, such seller-lessee, or the successors to or assigns of such seller-lessee’s estate, shall be the lessor under this Lease unless
and until such seller-lessee’s position shall have been assumed by such purchaser-lessor. 
 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 part thereof, when due, which failure is not cured
within five (5) days after written notice from Landlord that said amount was not paid when due, provided that if Tenant has previously received one (1) or more notices from Landlord during the immediately preceding twelve (12) month
period stating that Tenant failed to pay any amount required to be paid by Tenant under this Lease when due, then Landlord shall not be required to deliver any notice to Tenant and a default shall immediately occur upon any failure by Tenant to pay
any Rent when due; or 
 19.1.2    Except as otherwise specifically set forth in this Section 19.1, any failure by
Tenant to observe or perform any other provision, covenant or condition of this Lease to be observed or performed by Tenant where such failure continues for thirty (30) days after written notice thereof from Landlord to Tenant; provided that if
the nature of such default is such that the same cannot reasonably be cured within a thirty (30) day period, Tenant shall not be deemed to be in default if it diligently commences such cure within such period and thereafter diligently proceeds
to rectify and cure such default; or 
 19.1.3    Abandonment of all or a substantial portion of the Premises by Tenant;
or 
 19.1.4    Any Transfer in violation of Article 14 or the failure by Tenant to observe or
perform according to the provisions of Articles 17 or 18 of this Lease, or any breach by Tenant of the representations and warranties set forth in Section 29.34 of this Lease, where such failure continues
for more than three (3) business days after notice from Landlord; or 
 19.1.5    The failure by Tenant to observe
or perform according to the provisions of Articles 5 and 10 of this Lease, where such failure continues for more than five (5) business days after notice from Landlord.

 The notice periods provided in this Section 19.1 are in lieu of, and
not in addition to, any notice periods provided by law, provided that such notices are personally served in the manner prescribed by California Code of Civil Procedure Section 1162 (b). 

19.2    Remedies Upon Default. Upon the occurrence of any default beyond any applicable notice and cure
periods by Tenant, Landlord shall have, in addition to any other remedies available to Landlord at law or in equity (all of which remedies shall be distinct, separate and cumulative), the option to pursue any one or more of the following remedies,
each and all of which shall be cumulative and nonexclusive, without any notice or demand whatsoever. 

19.2.1    Terminate this Lease, in which event Tenant shall immediately surrender the Premises to Landlord, and if Tenant
fails to do so, Landlord may, without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and take possession of the Premises and expel or remove Tenant and any other person who may be occupying the
Premises or any part thereof in accordance with Applicable Laws, 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 or which in the ordinary course of things would be likely to result therefrom, specifically including but not limited to, brokerage commissions and advertising expenses incurred, the unamortized
value of the Tenant Improvement Allowance as of the date of termination, and any special concessions made to obtain a new tenant to the extent attributable to the remaining balance of the Lease Term; 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
Rent. As used in Sections 19.2.1(i) and 19.2.1(ii), above, the “worth at the time of award” shall be computed by allowing interest at the rate set forth in Article 25 of this Lease, but in no case greater than the
maximum amount of such interest permitted by law. As used in Section 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. 
 19.2.3    Landlord shall at all times have the rights and remedies (which shall be cumulative with each
other and cumulative and in addition to those rights and remedies available under Sections 19.2.1 and 19.2.2, above, or any law or other provision of this Lease), without prior demand or notice except as required by
applicable law, to seek any declaratory, injunctive or other equitable relief, and specifically enforce this Lease, or restrain or enjoin a violation or breach of any provision hereof. 

19.3    Subleases of Tenant. If Landlord elects to terminate this Lease on account of any default by Tenant,
as set forth in this Article 19, then Landlord shall have the right, at Landlord’s option in its sole discretion, (i) to terminate any and all assignments, subleases, licenses, concessions or other consensual
arrangements for possession entered into by Tenant and affecting the Premises, in which event Landlord shall have the right to repossess such affected portions of the Premises by any lawful means, or (ii) to succeed to Tenant’s interest in
any or all such assignments, subleases, licenses, concessions or arrangements, in which event Landlord may require any assignees, sublessees, licensees or other parties thereunder to attorn to and recognize Landlord as its assignor, sublessor,
licensor, concessionaire or transferor thereunder. In the event of Landlord’s election to succeed to Tenant’s interest in any such assignments, subleases, licenses, concessions or arrangements, Tenant shall, as of the date of notice by
Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder. 

19.4    Efforts to Relet. No re-entry or repossession, repairs,
maintenance, changes, alterations and additions, reletting, appointment of a receiver to protect Landlord’s interests hereunder, or any other action or omission by Landlord shall be construed as an election by Landlord to terminate this Lease
or Tenant’s right to possession, or to accept a surrender of the Premises, nor shall same operate to release Tenant in whole or in part from any of Tenant’s obligations hereunder, unless express written notice of such intention is sent by
Landlord to Tenant. Tenant hereby irrevocably waives any right otherwise available under any law to redeem or reinstate this Lease. 

ARTICLE 20 
 COVENANT

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 

SECURITY DEPOSIT 

Concurrent with Tenant’s execution of this Lease, Tenant shall deposit with Landlord a security deposit (the “Security
Deposit”) in the amount set forth in Section 8 of the Summary, as security for the faithful performance by Tenant of all of its obligations under this Lease. If Tenant defaults with respect to any provisions of
this Lease and such default is not cured prior to the expiration of any applicable notice and cure periods, including, but not limited to, the provisions relating to the payment of Rent, the removal of property and the repair of resultant damage,
Landlord may, without further notice to Tenant, but shall not be required to apply all or any part of the Security Deposit for the payment of any Rent or any other sum in default and Tenant shall, upon demand therefor, restore the Security Deposit
to its original amount. Any unapplied portion of the Security Deposit shall be returned to Tenant, or, at Landlord’s option, to the last assignee of Tenant’s interest hereunder, within sixty (60) days following the expiration of the
Lease Term. Tenant shall not be entitled to any interest on the Security Deposit and Landlord shall have the right to commingle the Security Deposit with Landlord’s other funds. Tenant hereby waives the provisions of Section 1950.7 of the
California Civil Code and all other provisions of law, now or hereafter in effect, which (i) establish the time frame by which a landlord must refund a security deposit under a lease, and/or (ii) provide that a landlord may claim from a
security deposit only those sums reasonably necessary to remedy defaults in the payment of rent, to repair damage caused by a tenant or to clean the premises, it being agreed that Landlord may, in addition, claim those sums specified in this
Article 21 above and/or those sums reasonably necessary to compensate Landlord for any loss or damage caused by Tenant’s default of this Lease, including, but not limited to, all damages or rent due upon termination of
this Lease pursuant to Section 1951.2 of the California Civil Code. 
 ARTICLE 22 

SUBSTITUTION OF OTHER PREMISES 

Landlord shall have the right to relocate Tenant to other space (the “Relocation Space”) located on the fifth (5th) floor or higher in the Project comparable to the Premises (e.g. reasonably comparable views, comparable finishes, comparable number of offices and conference rooms, comparable ceiling treatment,
doors and hardware), and tenant improvements of equal or greater quality than those then-existing in the Premises, and all terms hereof shall apply to the Relocation Space with equal force and effect, except as otherwise provided in this
Article 22. To the extent Tenant request any upgrades in the improvements located in such Relocation Space vis-à-vis the
improvements then existing in the Premises (e.g., specialty finishes such as glass, ceiling treatments, specialty lighting, built-in or custom cabinetry), Tenant shall pay to Landlord, promptly upon billing
therefor, all costs and expenses incurred by Landlord in connection with such upgraded improvements. In such event, Landlord shall give Tenant not less than ninety (90) days’ prior written notice of Landlord’s election to so
relocate

Tenant, and shall move Tenant’s effects to the Relocation Space at Landlord’s sole cost and expense at such time and in such manner as to inconvenience Tenant as little as reasonably
practicable. Landlord shall reimburse Tenant for all actual out-of-pocket costs incurred by Tenant in connection with its move from the Premises to the Relocation
Space, including, without limitation, the cost to install new communications and computer lines (to the extent not installed by Landlord as part of its installation of the tenant improvements in the Relocation Space), the cost to move Tenant’s
furniture from the Premises to the Relocation Space, and the cost of reasonable amounts of replacement stationery. Simultaneously with such relocation of the Premises, the parties shall immediately execute an amendment to this Lease (or, if
the Relocation Space is in a building of the Project other than the Building, Tenant shall execute a new lease with the owner of such building, which shall be on substantially the same terms and conditions as this Lease, and Tenant and Landlord
shall enter into a termination of this Lease) stating the relocation of the Premises, and amending those Sections of the Summary, and replacing Exhibit A to this Lease, as shall be necessary to
accurately describe the Relocation Space (including, without limitation, the location and the rentable area of the Relocation Space). In the event Tenant is relocated in accordance with this Article 22, and the
rentable area of the Relocation Space is not equal to the rentable area of the Premises, or any such adjustment to the rentable area of the Premises and/or the Building, or if the Relocation Space is in a building of the Project other than the
Building and the rentable area of such other building is not equal to the rentable area of the Building, all amounts, percentages and figures appearing or referred to in this Lease based upon such rentable area (including, without limitation, the
amounts of the “Rent” and the “Security Deposit,” as those terms are defined in Article 4 and Article 21 of this Lease, respectively, and “Tenant’s Share,” as
that term is defined in Section 4.2.9 of this Lease) shall be modified accordingly; provided, however, that notwithstanding the foregoing, (i) in no event shall the rentable area of the Relocation Space be less than
one hundred percent (100%) of the rentable area of the Premises; and (ii) Tenant’s Base Rent and Tenant’s Share shall not increase as a result of such relocation. Should Tenant unreasonably refuse to move to the Relocation Space
designated by Landlord, Landlord shall have the right to cancel and terminate this Lease effective ninety (90) days from the date of Landlord’s election to relocate Tenant. 

ARTICLE 23 
 SIGNS

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

23.2    Multi-Tenant Floors. If other tenants occupy space on the floor on which the Premises is located,
Tenant’s identifying signage shall be provided by Landlord, at Tenant’s cost, on the Building-standard directory signs in the ground floor lobby of the Building and in the elevator lobby on the Tenant’s floor, and such signage shall
be comparable to that used by Landlord for other similar floors in the Building and shall comply with Landlord’s then-current Building standard signage program.

 23.3    Prohibited Signage and Other Items. Any signs, notices,
logos, pictures, names or advertisements which are installed, are visible from the exterior of the Premises, and that have not been separately approved by Landlord may be removed without notice by Landlord at the sole expense of Tenant. Tenant may
not install any signs on the exterior or roof of the Project or the Common Areas. Any signs, window coverings, or blinds (even if the same are located behind the Landlord-approved window coverings for the Building), or other items visible from the
exterior of the Premises or Building, shall be subject to the prior approval of Landlord, in its sole discretion. 
 ARTICLE 24 

COMPLIANCE WITH LAW 

24.1    In General. Tenant shall not do anything or permit anything to be done in or about the Premises or
the Project which will in any way conflict with any law, statute, ordinance or other governmental rule, regulation or requirement now in force or which may hereafter be enacted or promulgated, including any such governmental regulations related to
disabled access (collectively, “Applicable Laws”). At its sole cost and expense, Tenant shall promptly comply with any Applicable Laws which relate to (i) the Premises (excluding the Building outside of the Premises and the
Base Building within the Premises except as set forth in item (iii), below), (ii) any Alterations made by Tenant to the Premises, and any Tenant Improvements in the Premises, or (iii) the Base Building, but as to the Base Building, only to
the extent such obligations are triggered by Alterations made by Tenant to the Premises to the extent such Alterations are not normal and customary business office improvements, or triggered by the Tenant Improvements to the extent such Tenant
Improvements are not normal and customary business office improvements, or triggered by Tenant’s use of the Premises for non-general office use, or triggered by Tenant’s occupancy of the Premises at
a density level greater than the normal general office occupancy density at the Project (collectively, “Tenant’s Compliance With Law Obligations”). Should any standard or regulation now or hereafter be imposed on Landlord or
Tenant by a state, federal or local governmental body charged with the establishment, regulation and enforcement of occupational, health or safety standards for employers, employees, landlords or tenants, then Tenant agrees, at its sole cost and
expense, to comply promptly with such standards or regulations and to cooperate with Landlord, including, without limitation, by taking such actions as Landlord may reasonably require, in Landlord’s efforts to comply with such standards or
regulations. Tenant shall be responsible, at its sole cost and expense, to make all alterations to the Premises as are required in connection with Tenant’s Compliance With Law Obligations. The judgment of any court of competent jurisdiction or
the admission of Tenant in any judicial action, regardless of whether Landlord is a party thereto, that Tenant has violated any of said governmental measures, shall be conclusive of that fact as between Landlord and Tenant. Tenant shall promptly pay
all fines, penalties and damages that may arise out of or be imposed because of its failure to comply with the provisions of this Article 24. Landlord shall comply with all Applicable Laws relating to the Base Building and
the Common Areas, provided that compliance with such Applicable Laws is not the

responsibility of Tenant under this Lease, and provided further that Landlord’s failure to comply therewith would prohibit Tenant from obtaining or maintaining a certificate of occupancy for
the Premises, or would unreasonably and materially affect the safety of Tenant’s employees or create a material health hazard for Tenant’s employees, or would otherwise materially and adversely affect Tenant’s use of or access to the
Premises. Landlord shall be permitted to include in Operating Expenses any costs or expenses incurred by Landlord under this Article 24 to the extent not prohibited by the terms of Article 4 of this Lease, above.
Tenant hereby agrees to use reasonable efforts to notify Landlord if Tenant makes any Alterations or improvements to the Premises that might impact accessibility to the Premises or the Building under any disability access laws. Landlord hereby
agrees to use reasonable efforts to notify Tenant if Landlord makes any alterations or improvements to the Premises that might impact accessibility to the Premises or the Building under any disability access laws. 

24.2    Statutory Disclosure and Related Terms. For purposes of Section 1938(a) of the California Civil
Code, Landlord hereby discloses to Tenant, and Tenant hereby acknowledges, that to Landlord’s actual knowledge, the Premises have not undergone inspection by a Certified Access Specialist (CASp). As required by Section 1938(e) of the
California Civil Code, Landlord hereby states as follows: “A Certified Access Specialist” (CASp) can inspect the subject premises and determine whether the subject premises comply with all of the applicable construction-related
accessibility standards under state law. Although state law does not require a CASp inspection of the subject premises, the commercial property owner or lessor may not prohibit the lessee or tenant from obtaining a CASp inspection of the subject
premises for the occupancy or potential occupancy of the lessee or tenant, if requested by the lessee or tenant. The parties shall mutually agree on the arrangements for the time and manner of the CASp inspection, the payment of the fee for the CASp
inspection, and the cost of making any repairs necessary to correct violations of construction-related accessibility standards within the premises.” In furtherance of the foregoing, Landlord and Tenant hereby agree as follows: (a) any CASp
inspection requested by Tenant shall be conducted, at Tenant’s sole cost and expense, by a CASp reasonably approved by Landlord, subject to Landlord’s reasonable rules and requirements; (b) Tenant, at its sole cost and expense, shall
be responsible for making any improvements or repairs within the Premises to correct violations of construction-related accessibility standards; and (c) Subject to Section 24.1, above, if anything done by or for Tenant
in its use or occupancy of the Premises shall require any improvements or repairs to the Building or Project (outside the Premises) to correct violations of construction-related accessibility standards, then Tenant shall reimburse Landlord within
thirty (30) days after demand, as Additional Rent, for the reasonable cost actually incurred by Landlord of performing such improvements or repairs. The terms of this Section 24.3 do not amend or reduce the obligations
of Landlord and Tenant set forth in this Lease regarding compliance with Applicable Laws and repair and maintenance of the Premises and the Project, but apply solely to the obligations of Landlord and Tenant in connection with Tenant’s election
to conduct a CASp inspection hereunder.

 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 (i) within five (5) days after written notice from Landlord that said amount was not paid when due, or (ii) upon
the date said amount is due, if Tenant has previously received one (1) or more notices from Landlord during the immediately preceding twelve (12) month period stating that Tenant failed to pay any amount required to be paid by Tenant under
this Lease when due, then Tenant shall pay to Landlord a late charge equal to six percent (6%) of the overdue amount plus any attorneys’ fees incurred by Landlord by reason of Tenant’s failure to pay Rent and/or other charges when due
hereunder. The late charge shall be deemed Additional Rent and the right to require it shall be in addition to all of Landlord’s other rights and remedies hereunder or at law and shall not be construed as liquidated damages or as limiting
Landlord’s remedies in any manner. In addition to the late charge described above, any Rent or other amounts owing by Tenant to Landlord hereunder which are not paid (A) within five (5) days after written notice from Landlord that
said amount was not paid when due, or (B) upon the date said amount is due, if Tenant has previously received one (1) or more notices from Landlord during the immediately preceding twelve (12) month period stating that Tenant failed
to pay any amount required to be paid by Tenant under this Lease when due, shall bear interest from the date when due until paid at a rate per annum equal to the lesser of (x) the annual “Bank Prime Loan” rate cited in the
Federal Reserve Statistical Release publication H.15(519), published weekly (or such other comparable index as Landlord and Tenant shall reasonably agree upon if such rate ceases to be published) plus four (4) percentage points, and
(y) the highest rate permitted by Applicable Law. 
 ARTICLE 26 

LANDLORD’S RIGHT TO CURE DEFAULT; PAYMENTS BY TENANT 

26.1    Landlord’s Cure. All covenants and agreements to be kept or
performed by Tenant under this Lease shall be performed by Tenant at Tenant’s sole cost and expense and without any reduction of Rent, except to the extent, if any, otherwise expressly provided herein. If Tenant shall fail to perform any
obligation under this Lease, and such failure shall continue in excess of the time allowed under Section 19.1.2, Section 19.1.4 or Section 19.1.5, above, or if the failure
by Tenant to observe or perform any provision, covenant or condition of this Lease which failure, because of the character of such provision, covenant or condition, would immediately jeopardize Landlord’s interest, Landlord may, but shall not
be obligated to, make any such payment or perform any such act on Tenant’s part without waiving its rights based upon any default of Tenant and without releasing Tenant from any obligations hereunder. 

26.2    Tenant’s Reimbursement. Except as may be specifically provided to the contrary in this Lease,
Tenant shall pay to Landlord the following sums (which sums shall bear interest from the date accrued by Landlord until paid by Tenant at a rate per annum equal to interest at the rate set forth in Article 25 of this Lease,
but in no case greater than the maximum amount of such interest permitted by law), within ten (10) business days after delivery by Landlord to Tenant of statements therefor: (i) sums equal to expenditures reasonably made and obligations
incurred by Landlord in connection with the remedying by Landlord of Tenant’s defaults pursuant to the provisions of Section 26.1; (ii) sums equal to all losses, costs, liabilities, damages and expenses referred
to in Section 10.1 of this Lease; and (iii) sums equal to all

expenditures made and obligations incurred by Landlord in collecting or attempting to collect the Rent or in enforcing or attempting to enforce any rights of Landlord under this Lease or pursuant
to law, including, without limitation, all legal fees and other amounts so expended. Tenant’s obligations under this Section 26.2 shall survive the expiration or sooner termination of the Lease Term. 

ARTICLE 27 
 ENTRY BY
LANDLORD 
 Landlord reserves the right at all reasonable times and upon reasonable prior notice to Tenant, which notice:
(a) shall not be less than 24 hours in advance, (b) notwithstanding anything to the contrary contained in Article 28 of this Lease, may be oral, and (c) which notice shall not be required in the case of an
emergency, to enter the Premises to (i) inspect them; (ii) show the Premises to prospective purchasers or tenants, or to current or prospective mortgagees, ground or underlying lessors or insurers; (iii) post notices of
nonresponsibility; or (iv) alter, improve or repair the Premises or the Building, or for structural alterations, repairs or improvements to the Building or the Building’s systems and equipment. Notwithstanding anything to the contrary
contained in this Article 27, Landlord may enter the Premises at any time to (A) perform services required of Landlord, including janitorial service; (B) take possession due to any breach of this Lease in the
manner provided herein; and (C) perform any covenants of Tenant which Tenant fails to perform. Landlord may make any such entries without the abatement of Rent and may take such reasonable steps as required to accomplish the stated purposes.
Tenant hereby waives any claims for damages or for any injuries or inconvenience to or interference with Tenant’s business, lost profits, any loss of occupancy or quiet enjoyment of the Premises, and any other loss occasioned thereby. For each
of the above purposes, Landlord shall at all times have a key with which to unlock all the doors in the Premises, excluding Tenant’s vaults, safes and special security areas designated in advance by Tenant. In an emergency, Landlord shall have
the right to use any means that Landlord may deem proper to open the doors in and to the Premises. Any entry into the Premises by Landlord in the manner hereinbefore described shall not be deemed to be a forcible or unlawful entry into, or a
detainer of, the Premises, or an actual or constructive eviction of Tenant from any portion of the Premises. No provision of this Lease shall be construed as obligating Landlord to perform any repairs, alterations or decorations except as otherwise
expressly agreed to be performed by Landlord herein. In connection with any entry into the Premises, Landlord shall comply with Tenant’s reasonable security measures and operating procedures and shall use commercially reasonable efforts to
minimize interference with Tenant’s conduct of business at the Premises, but in no event shall any Landlord Party be required to execute a nondisclosure or confidentiality agreement in order to enter the Premises. 

ARTICLE 28 
 NOTICES

 All notices, demands, designations, approvals or other communications (collectively, “Notices”) given or
required to be given by either party to the other hereunder or by law shall be in writing, shall be (A) sent by United States certified or registered mail, postage prepaid, return

 29.2    Binding Effect. Subject to all other provisions of this
Lease, each of the covenants, conditions and provisions of this Lease shall extend to and shall, as the case may require, bind or inure to the benefit not only of Landlord and of Tenant, but also of their respective heirs, personal representatives,
successors or assigns, provided this clause shall not permit any assignment by Tenant contrary to the provisions of Article 14 of this Lease. 

29.3    No Light, Air or View Rights. No rights to any view or to light or air over any property, whether
belonging to Landlord or any other person, are granted to Tenant by this Lease. Under no circumstances whatsoever at any time during the Lease Term shall any temporary darkening of any windows of the Premises or any temporary obstruction of the
light or view therefrom by reason of any repairs, improvements, maintenance or cleaning in or about the Project, or any diminution, impairment or obstruction (whether partial or total) of light, air or view by any structure which may be erected on
any land comprising a part of, or located adjacent to or otherwise in the path of light, air or view to, the Project, in any way impose any liability upon Landlord or in any way reduce or diminish Tenant’s obligations under this Lease. 

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

29.5    Transfer of Landlord’s Interest. Tenant acknowledges that Landlord
has the right to transfer all or any portion of its interest in the Project or Building and in this Lease, and Tenant agrees that in the event of any such transfer, Landlord shall automatically be released from all liability under this Lease and
Tenant agrees to look solely to such transferee for the performance of Landlord’s obligations hereunder after the date of transfer provided that the transferee shall have fully assumed in writing and agreed to be liable for all obligations of
this Lease to be performed by Landlord, including the return of any Security Deposit, and Tenant shall attorn to such transferee. 

29.6    Prohibition Against Recording. Except as provided in Section 29.4 of this
Lease, neither this Lease, nor any memorandum, affidavit or other writing with respect thereto, shall be recorded by Tenant or by anyone acting through, under or on behalf of Tenant.

Tenant. Nothing herein contained shall empower Tenant to do any act which can, shall or may encumber the title of Landlord. 

29.8    Relationship of Parties. Nothing contained in this Lease shall be deemed or construed by the parties
hereto or by any third party to create the relationship of principal and agent, partnership, joint venturer or any association between Landlord and Tenant.

 29.9    Application of Payments. Landlord shall have the right
to apply payments received from Tenant pursuant to this Lease, regardless of Tenant’s designation of such payments, to satisfy any obligations of Tenant hereunder, in such order and amounts as Landlord, in its sole discretion, may elect. 

29.10    Time of Essence. Time is of the essence with respect to the performance of every provision of this
Lease in which time of performance is a factor, including, without limitation, the giving of any Notice required to be given under this Lease or by law, the time periods for giving any such Notice and the taking of any action with respect to any
such Notice. 
 29.11    Partial Invalidity. If any term, provision or condition contained in this Lease
shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application of such term, provision or condition to persons or circumstances other than those with respect to which it is invalid or unenforceable, shall not be
affected thereby, and each and every other term, provision and condition of this Lease shall be valid and enforceable to the fullest extent possible permitted by law. 

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

29.13    Exculpation. 

29.13.1    Landlord Exculpation. The liability of Landlord or the Landlord Parties to Tenant for any default
by Landlord under this Lease or arising in connection herewith or with Landlord’s operation, management, leasing, repair, renovation, alteration or any other matter relating to the Project or the Premises shall be limited solely and exclusively
to an amount which is equal to the interest of Landlord in the Building and the rents, issues and profits thereof. Neither Landlord, nor any of the Landlord Parties shall have any personal liability therefor, and Tenant hereby expressly waives and
releases such personal liability on behalf of itself and all persons claiming by, through or under Tenant. The limitations of liability contained in this Section 29.13 shall inure to the benefit of Landlord’s and the
Landlord Parties’ present and future partners, beneficiaries, officers, directors, trustees, shareholders, agents and employees, and their respective partners, heirs, successors and assigns. Under no circumstances shall any present or future
partner of Landlord (if Landlord is a partnership), or trustee or beneficiary (if Landlord or any partner of Landlord is a trust), have any personal liability for the performance of Landlord’s obligations under this Lease. Notwithstanding any

damages or any injury or damage to, or interference with, Landlord’s business, including, but not limited to, loss of profits, loss of rents or other revenues, loss of business opportunity,
loss of goodwill or loss of use, in each case, however occurring, other than those damages incurred by Landlord in connection with a holdover of the Premises by Tenant after the expiration or earlier termination of this Lease, subject to Article
16, above. 
 29.14    Entire Agreement. It is understood and acknowledged that there are no oral
agreements between the parties hereto affecting this Lease and this Lease constitutes the parties’ entire agreement with respect to the leasing of the Premises and supersedes and cancels any and all previous negotiations, arrangements,
brochures, agreements and understandings, if any, between the parties hereto or displayed by Landlord to Tenant with respect to the subject matter thereof, and none thereof shall be used to interpret or construe this Lease. None of the terms,
covenants, conditions or provisions of this Lease can be modified, deleted or added to except in writing signed by the parties hereto. 

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

29.17    Waiver of Redemption by Tenant. Tenant hereby waives, for Tenant and for all those claiming under
Tenant, any and all rights now or hereafter existing to redeem by order or judgment of any court or by any legal process or writ, Tenant’s right of occupancy of the Premises after any termination of this Lease. 

29.18    Tenant Parking. Tenant shall have the right to park 3.3 passenger vehicles for every 1,000 rentable
square feet in the Premises, free of charge, in the portions of the Common Areas designated by Landlord for vehicular parking. Such parking shall be on an as available “first-come, first-served” basis which shall be in common with all
other tenants of the Project. Tenant shall abide by all reasonable rules and regulations which are prescribed from time to time for the orderly operation and use of the parking facility, including any sticker or other identification system
established by Landlord, and Tenant shall cooperate reasonably in seeing that Tenant’s employees and visitors also comply with such rules and regulations. Landlord specifically reserves the right to change the size, configuration, design,
layout and all other aspects of the Project parking facility at any time and Tenant acknowledges and agrees that

Landlord may, without incurring any liability to Tenant and without any abatement of Rent under this Lease, from time to time, temporarily close-off or
restrict access to the Project parking facility for purposes of permitting or facilitating any such construction, alteration or improvements, provided that: (a) Landlord provides the number of parking spaces required in the first sentence of
this Section 29.18, and (b) any closings, restrictions, or changes will similarly impact all of the tenants of the Project. If Landlord relocates the parking facility (either temporarily or otherwise) to an area not
within the Project, Landlord shall provide, at no cost to Tenant, shuttle bus service from such relocated parking area to the Building for so long as the parking area is not located within the Project. Landlord may delegate its responsibilities
hereunder to a parking operator in which case such parking operator shall have all the rights of control attributed hereby to the Landlord. The parking passes rented by Tenant pursuant to this Section 29.18 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 (except in connection with a transfer to a Permitted Transferee) without Landlord’s prior
approval. Tenant may validate visitor parking by such method or methods as the Landlord may establish, at the validation rate from time to time generally applicable to visitor parking. 

29.19    Joint and Several. If there is more than one Tenant, the obligations imposed upon Tenant under this
Lease shall be joint and several. 
 29.20    Authority. If Tenant is a corporation, trust, limited
liability company or partnership, Tenant hereby represents and warrants that Tenant is a duly formed and existing entity qualified to do business in California and that Tenant has full right and authority to execute and deliver this Lease and that
each person signing on behalf of Tenant is authorized to do so. In such event, Tenant shall, within ten (10) days after execution of this Lease, deliver to Landlord satisfactory evidence of such authority and, if a corporation, upon demand by
Landlord, also deliver to Landlord satisfactory evidence of (i) good standing in Tenant’s state of incorporation and (ii) qualification to do business in California. Landlord hereby represents and warrants that: (a) Landlord is a
duly formed and existing entity qualified to do business in California, (b) Landlord has the full right and authority to execute and deliver this Lease without the necessary consent of any other person or entity, and (c) the person signing
this Lease on behalf of Landlord is authorized to do so. 
 29.21    Attorneys’ Fees. In the event
that either Landlord or Tenant should bring suit for the possession of the Premises, for the recovery of any sum due under this Lease, or because of the breach of any provision of this Lease or for any other relief against the other, then all costs
and expenses, including reasonable attorneys’ fees, incurred by the prevailing party therein shall be paid by the other party, which obligation on the part of the other party shall be deemed to have accrued on the date of the commencement of
such action and shall be enforceable whether or not the action is prosecuted to judgment. 
 29.22    Governing
Law; WAIVER OF TRIAL BY JURY. This Lease shall be construed and enforced in accordance with the laws of the State of California. IN ANY ACTION OR PROCEEDING ARISING HEREFROM, LANDLORD AND TENANT HEREBY CONSENT TO (I) THE JURISDICTION OF
ANY COMPETENT COURT WITHIN THE STATE OF CALIFORNIA, (II) SERVICE OF PROCESS BY ANY MEANS AUTHORIZED BY CALIFORNIA LAW, AND (III) IN THE INTEREST OF SAVING TIME AND EXPENSE,

CONNECTION WITH THIS LEASE, THE RELATIONSHIP OF LANDLORD AND TENANT, TENANT’S USE OR OCCUPANCY OF THE PREMISES, AND/OR ANY CLAIM FOR INJURY OR DAMAGE, OR ANY EMERGENCY OR STATUTORY REMEDY. IN THE EVENT LANDLORD COMMENCES ANY SUMMARY PROCEEDINGS
OR ACTION FOR NONPAYMENT OF BASE RENT OR ADDITIONAL RENT, TENANT SHALL NOT INTERPOSE ANY COUNTERCLAIM OF ANY NATURE OR DESCRIPTION (UNLESS SUCH COUNTERCLAIM SHALL BE MANDATORY) IN ANY SUCH PROCEEDING OR ACTION, BUT SHALL BE RELEGATED TO AN
INDEPENDENT ACTION AT LAW. 
 29.23    Submission of Lease. Submission of this instrument for examination
or signature by Tenant does not constitute a reservation of, option for or option to lease, and it is not effective as a lease or otherwise until execution and delivery by both Landlord and Tenant. 

29.24    Brokers. Landlord and Tenant hereby warrant to each other that they have had no dealings with any
real estate broker or agent in connection with the negotiation of this Lease, excepting only the real estate brokers or agents specified in Section 11 of the Summary (the “Brokers”), and that they know of
no other real estate broker or agent who is entitled to a commission in connection with this Lease. Each party agrees to indemnify and defend the other party against and hold the other party harmless from any and all claims, demands, losses,
liabilities, lawsuits, judgments, costs and expenses (including without limitation reasonable attorneys’ fees) with respect to any leasing commission or equivalent compensation alleged to be owing on account of any dealings with any real estate
broker or agent, other than the Brokers, occurring by, through, or under the indemnifying party. 

29.25    Independent Covenants. This Lease shall be construed as though the covenants herein between
Landlord and Tenant are independent and not dependent and Tenant hereby expressly waives the benefit of any statute to the contrary and agrees that if Landlord fails to perform its obligations set forth herein, Tenant shall not be entitled to make
any repairs or perform any acts hereunder at Landlord’s expense or to any setoff of the Rent or other amounts owing hereunder against Landlord. 

29.26    Project or Building Name and Signage. Landlord shall have the right at any time to change the name
of the Project or Building and to install, affix and maintain any and all signs on the exterior and on the interior of the Project or Building as Landlord may, in Landlord’s sole discretion, desire. Tenant shall not use the words
“Gateway Center” or the name of the Project or Building or use pictures or illustrations of the Project or Building in advertising or other publicity or for any purpose other than as the address of the business to be conducted by
Tenant in the Premises, without the prior written consent of Landlord. 
 29.27    Counterparts. This
Lease may be executed in counterparts with the same effect as if both parties hereto had executed the same document. Both counterparts shall be construed together and shall constitute a single lease.

increased Rent, or any costs or charges upon Tenant, or otherwise materially and adversely affect Tenant’s right or obligations under this Lease. Nothing contained herein shall be deemed or construed to limit or otherwise affect Landlord’s
right to convey all or any portion of the Project or any other of Landlord’s rights described in this Lease. 

29.29.3    Construction of Project and Other Improvements. Tenant acknowledges that portions of the Project
and/or the Other Improvements may be under construction following Tenant’s occupancy of the Premises, and that such construction may result in levels of noise, dust, odor, obstruction of access, etc. which are in excess of that present in a
fully constructed project. Tenant hereby waives any and all rent offsets or claims of constructive eviction which may arise in connection with such construction. 

29.30    Building Renovations. It is specifically understood and agreed that Landlord has no obligation and

materially, adversely affect Tenant’s use of or access to the Premises. Notwithstanding the foregoing, Tenant hereby agrees that such Renovations shall in no way constitute a constructive
eviction of Tenant nor entitle Tenant to any abatement of Rent. Landlord shall have no responsibility and shall not be liable to Tenant for any injury to or interference with Tenant’s business arising from the Renovations, nor shall
Tenant be entitled to any compensation or damages from Landlord for any inconvenience or annoyance occasioned by such Renovations. 

29.31    No Violation. Tenant hereby warrants and represents that neither its execution of nor performance
under this Lease shall cause Tenant to be in violation of any agreement, instrument, contract, law, rule or regulation by which Tenant is bound, and Tenant shall protect, defend, indemnify and hold Landlord harmless against any claims, demands,
losses, damages, liabilities, costs and expenses, including, without limitation, reasonable attorneys’ fees and costs, arising from Tenant’s breach of this warranty and representation. Landlord hereby warrants and represents that neither
its execution of nor performance under this Lease shall cause Landlord, to be in violation of any agreement, instrument, contract, law, rule or regulation by which Landlord is bound, and Landlord shall protect, defend, indemnify and hold Tenant

installation of new Lines, Landlord may require that Tenant remove existing Lines located in the Premises and repair any damage in connection with such removal, and (vi) Tenant shall pay all costs in connection therewith. Landlord reserves the
right to require that Tenant remove any Lines located in-the Premises which are installed by Tenant in violation of these provisions, in violation of any laws or which represent a dangerous or potentially dangerous condition. Landlord further
reserves the right to require that Tenant remove any and all Lines located in the Premises that were installed by Tenant upon the expiration of the Lease Term or upon any earlier termination of this Lease.

29.34    No Discrimination. There shall be no discrimination against, or segregation of, any person or
persons on account of sex, marital status, race, color, religion, creed, national origin or ancestry in the Transfer of the Premises, or any portion thereof, nor shall the Tenant itself, or any person claiming under or through it, establish or

TENANT WORK LETTER 

This Tenant Work Letter shall set forth the terms and conditions relating to the construction of the Tenant Improvements in the Premises. This
Tenant Work Letter is essentially organized chronologically and addresses the issues of the construction of the Premises, in sequence, as such issues will arise during the actual construction of the Premises. All references in this Tenant Work
Letter to Articles or Sections of “this Lease” shall mean the relevant portions of Articles 1 through 29 of the Office Lease to which this Tenant Work Letter is attached as Exhibit B, and
of which this Tenant Work Letter forms a part, and all references in this Tenant Work Letter to Sections of “this Tenant Work Letter” shall mean the relevant portions of Sections 1 through 5 of
this Tenant Work Letter. 
 SECTION 1 

DELIVERY OF THE PREMISES AND BASE BUILDING 

1.1    Base, Shell and Core. Landlord has constructed, at its sole cost and expense, the base, shell, and core
(i) of the Premises and (ii) of the floor of the Building on which the Premises is located (collectively, the “Base, Shell, and Core”). The Base, Shell and Core shall consist of the following elements: (A) base
Building systems located in the vertical risers, raceways, and shafts (including elevator shafts and equipment, the telecom riser exclusive of equipment owned by third parties, electrical rooms, stair shafts and mechanical shafts) up to but not
including the point of demarcation of such systems with the horizontal point of connection on a particular floor; (B) in the case of the sprinkler system, it shall additionally include the valve at the riser and the main sprinkler loop, but
shall exclude branch pipes; (C) the concrete floor at each floor level, and (D) the Building’s steel and concrete superstructure. Except as provided in Section 1.2 below, Tenant shall accept the Base, Shell
and Core from Landlord in their presently existing, “as-is” condition. 

1.2    Landlord Work. Landlord shall, at Landlord’s sole cost and expense, concurrently with Tenant’s
construction of the Tenant Improvements, cause the construction or installation of the following items on the floor of the Building containing the Premises (collectively, the “Landlord Work”). Tenant may not change or alter the
Landlord Work. 
 1.2.1    “Z” Corridor. Landlord shall construct a Building standard public corridor
wall, the standard tenant entries and exits, including doors, frames, hardware, and sidelight (if any), and standard tenant entry signage and exit lights (collectively, the “Z Corridor”), which
Z- Corridor shall be adjacent to the Premises as set forth on Schedule 1 to this Tenant Work Letter. 

1.2.2    Demising Wall. Landlord shall construct a Building standard demising partitions between Tenants and other
tenants on the seventh (7th) floor of the Building, which shall include studs, acoustical insulation and dry wall ready for finish on Tenant side only and any necessary penetrations, fire dampers
and sound traps (collectively, the “Demising Wall”),

LEGAL/JH-MY










 
which Demising Wall shall be adjacent to the Premises as set forth on Schedule 1 to this Tenant Work Letter. Landlord shall use commercially reasonable efforts to Substantially
Complete the Demising Wall on or before February 1, 2018. 
 In addition, Landlord shall, at Landlord’s sole cost and expense, to
the extent required in order to allow Tenant to obtain a certificate of occupancy, or its legal equivalent, for the Premises for general office use assuming a normal and customary office occupancy density, cause the Landlord Work and the Building
Common Areas (including the Base Building restrooms on the seventh (7th) floor of the Building), to comply with applicable building codes and other governmental laws, ordinances and regulations
related to handicap access, which were enacted and enforced as of the date of this Lease. 
 Because Landlord shall be constructing the
Landlord Work concurrently with Tenant’s construction of the Tenant Improvements, there will be a certain “overlap” period pursuant to which both Landlord’s representatives, employees, vendors and contractors and Tenant’s
representatives, employees, vendors and contractors may be present and performing work in a portion of the Premises. During any such “overlap” period(s) when both parties and/or their respective employees, vendors, contractors or
consultants are concurrently performing work in, or accessing, any portion of the Premises, neither party shall unreasonably interfere with or delay the work of the other party and/or its contractors or consultants, and both parties shall mutually
coordinate and cooperate with each other, and shall cause their respective employees, vendors, contractors, and consultants to work in harmony with and to mutually coordinate and cooperate with the other’s employees, vendors, contractors and
consultants, respectively, to minimize any interference or delay by either party with respect to the other party’s work. 

SECTION 2 
 TENANT
IMPROVEMENTS 
 2.1    Tenant Improvement Allowance. Tenant shall be entitled to a one-time tenant improvement allowance (the “Tenant Improvement Allowance”) in the amount set forth in Section 12 of the Summary, for the costs relating to the initial design and construction of
Tenant’s improvements, which are permanently affixed to the Premises (the “Tenant Improvements”). Except as provided in Section 2.2 below, in no event shall Landlord be obligated to make disbursements
pursuant to this Tenant Work Letter in a total amount which exceeds the Tenant Improvement Allowance. In the event that the Tenant Improvement Allowance is not fully utilized by Tenant by one (1) year after the later date this Lease is executed
by Landlord and Tenant, then such unused amounts shall revert to Landlord, and Tenant shall have no further rights with respect thereto. All Tenant Improvements for which the Tenant Improvement Allowance has been made available shall be deemed
Landlord’s property under the terms of the Lease; provided; however, that notwithstanding the foregoing, upon request by Tenant at the time of Tenant’s request for Landlord’s review of the Final Space Plan and/or the Final Working
Drawings, Landlord shall notify Tenant whether any of the Tenant Improvements will be required to be removed pursuant to the terms of this Section 2.1. Notwithstanding the foregoing or anything to the contrary in this
Lease, Tenant shall not be required to remove any Tenant Improvements, which are normal and customary business office improvements; provided, however, in any event Landlord may require Tenant to

remove all (i) rolling files and structural supports, (ii) built-in or high-density file systems, (iii) any supplemental HVAC system
installed by Tenant, (iv) any structural improvements, and (v) any security or information technology systems installed by or on behalf of Tenant in the Premises. 

2.2    Additional Allowance. Subject to the terms and conditions set forth in this
Section 2.2, Tenant shall be entitled to increase the Tenant Improvement Allowance by an amount not to exceed the amount set forth in Section 13 of the Summary (the “Additional Allowance”), pursuant to
a written notice delivered to Landlord on or before twelve (12) months from the later date this Lease is executed by Landlord and Tenant. In the event Tenant exercises its right to use all or any portion of the Additional Allowance, the monthly
Base Rent for the Premises shall be increased by an amount equal to the “Additional Monthly Base Rent,” as that term is defined below, in order to repay the Additional Allowance to Landlord. The “Additional Monthly Base
Rent” shall be determined as the missing component of an annuity, which annuity shall have (w) the amount of the Additional Allowance which Tenant elects to utilize as the present value amount, (x) the number of full calendar
months remaining in the Lease Term as the number of payments, (y) seven thousand eighty-three ten-thousands (.7083), which is equal to eight and one-half percent (8 1⁄2%) divided by twelve (12) months per year, as the monthly interest factor, and (z) the Additional Monthly Base Rent as the missing component of the
annuity. If Tenant elects to utilize all or a portion of the Additional Allowance, then (i) all references in this Tenant Work Letter to the “Tenant Improvement Allowance,” shall be deemed to include the Additional Allowance which
Tenant elects to utilize, (ii) the parties shall promptly execute an amendment (the “Additional Allowance Amendment”) to this Lease setting forth the new amount of the Base Rent, and Tenant Improvement Allowance computed in
accordance with this Section 2.2, (iii) Tenant shall deliver to Landlord, concurrently with Tenant’s execution and delivery of the Additional Allowance Amendment to Landlord, an additional Security Deposit and subject
to the terms and conditions of Article 21 of this Lease, in an amount equal to one-third (1/3) of the Additional Allowance.

 2.4.2    Disbursement of Tenant Improvement Allowance. During the
construction of the Tenant Improvements, Landlord shall make monthly disbursements of the Tenant Improvement Allowance for Tenant Improvement Allowance Items for the benefit of Tenant and shall authorize the release of monies for the benefit of
Tenant as follows:

payment of the “Contractor,” as that term is defined in Section 4.1 of this Tenant Work Letter, approved by Tenant, in a form to be provided by Landlord, showing the schedule, by trade, of percentage of completion

(A) the amounts so requested by Tenant, as set forth in this Section 2.4.2.1, above, less a ten percent (10%) retention (the aggregate amount of such retentions to be known as the “Final
Retention”), and (B) the balance of any remaining available portion of the Tenant Improvement Allowance (not including the Final Retention), provided that Landlord does not reasonably dispute any request for payment based on non-compliance of any work with the “Approved Working Drawings,” as that term is defined in Section 3.4 below, or due to any substandard work. Landlord’s payment of such
amounts shall not be deemed Landlord’s approval or acceptance of the work furnished or materials supplied as set forth in Tenant’s payment request. 

2.4.2.2    Final Retention. Subject to the provisions of this Tenant Work Letter, a check for the Final Retention
shall be delivered by Landlord to Tenant following the completion of construction of the Premises, provided that (i) Tenant delivers to Landlord properly executed mechanics lien releases in compliance with both California Civil Code
Section 3262(d)(2) and either Section 3262(d)(3) or Section 3262(d)(4), (ii) Landlord has reasonably determined that no substandard work exists which adversely affects the mechanical, electrical, plumbing, heating, ventilating
and air conditioning, life-safety or other systems of the Building, the curtain wall of the Building, the structure or exterior appearance of the Building, or any other tenant’s use of such other tenant’s leased premises in the Building
and (iii) Architect delivers to Landlord a certificate, in a form reasonably acceptable to Landlord, certifying that the construction of the Tenant Improvements in the Premises has been substantially completed. 

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

“Specifications”) for the Building standard components to be used in the construction of the Tenant Improvements in the Premises (collectively, the “Standard Improvement Package”), which Specifications have been

Specifications, provided that the Tenant Improvements shall comply with certain Specifications as designated by Landlord. Landlord may make reasonable changes to the Specifications for the
Standard Improvement Package from time to time, provided that Tenant shall not be required to make any changes to the Approved Working Drawings as a result of any such changes made after the Final Working Drawings have been approved by Landlord.

 SECTION 3 

CONSTRUCTION DRAWINGS 

3.1    Selection of Architect/Construction Drawings. Tenant has retained, and Landlord has approved, Brown Reynolds
Watford Architects as the architect/space planner (the “Architect”) to prepare the “Construction Drawings,” as that term is defined in this Section 3.1. Tenant shall also retain engineering
consultants selected by Tenant and reasonably approved by Landlord (the “Engineers”) to prepare all plans and engineering working drawings relating to the structural, mechanical, electrical, plumbing, HVAC, life safety, and
sprinkler work in the Premises, which work is not part of the Base Building. The plans and drawings to be prepared by Architect and the Engineers hereunder shall be known collectively as the “Construction Drawings.” Tenant shall be
required to include in its contracts with the Architect and the Engineers a provision which requires ownership of all Construction Drawings to be transferred to Tenant upon the Substantial Completion of the Tenant Improvements and Tenant hereby
grants to Landlord a non-exclusive right to use such Construction Drawings, including without limitation, making copies thereof. All Construction Drawings shall substantially comply with the drawing format and
specifications reasonably determined by Landlord, and shall be subject to Landlord’s reasonable approval. Tenant and Architect shall verify, in the field, the dimensions and conditions as shown on the relevant portions of the Base Building
plans, and Tenant and Architect shall be solely responsible for the same, and Landlord shall have no responsibility in connection therewith. Landlord’s review of the Construction Drawings as set forth in this
Section 3, shall be for its sole purpose and shall not imply Landlord’s review of the same, or obligate Landlord to review the same, for quality, design, Code compliance or other like matters. Accordingly,
notwithstanding that any Construction Drawings are reviewed by Landlord or its space planner, architect, engineers and consultants, and notwithstanding any advice or assistance which may be rendered to Tenant by Landlord or Landlord’s space
planner, architect, engineers, and consultants, Landlord shall have no liability whatsoever in connection therewith and shall not be responsible for any omissions or errors contained in the Construction Drawings, and Tenant’s waiver and
indemnity set forth in this Lease shall specifically apply to the Construction Drawings. 
 3.2    Final Space
Plan. Landlord and Tenant hereby approve that certain preliminary space plan for the Tenant Improvements prepared by Brown Reynolds Watford Architects, dated October 20, 2017, attached hereto as Schedule I (the “Final

business days after such delivery, Landlord shall either approve such Final Working Drawings or deliver to Tenant written notice of the specific, reasonable changes that Landlord requires to
conform the Final Working Drawings to the Final Space Plan. If Landlord reasonably disapproves the Final Working Drawings, Tenant shall make such changes and resubmit the revised Final Working Drawings to Landlord for its reasonable approval.
Landlord and Tenant shall continue such process until Landlord has reasonably approved the Final Working Drawings. 

3.4    Permits. The Final Working Drawings shall be approved by Landlord (the “Approved Working
Drawings”) prior to the commencement of the construction of the Tenant Improvements. Tenant shall promptly submit the Approved Working Drawings to the appropriate municipal authorities for all applicable building permits necessary to allow
“Contractor,” as that term is defined in Section 4.1, below, to commence and fully complete the construction of the Tenant Improvements (the “Permits”), and, in connection therewith, Tenant shall
coordinate with Landlord in order to allow Landlord, at its option, to take part in all phases of the permitting process and shall supply Landlord, as soon as possible, with all plan check numbers and dates of submittal and obtain the Permits.
Notwithstanding anything to the contrary set forth in this Section 3.4, Tenant hereby agrees that neither Landlord nor Landlord’s consultants shall be responsible for obtaining any building permit or certificate of
occupancy for the Premises and that the obtaining of the same shall be Tenant’s responsibility; provided however that Landlord shall, in any event, cooperate with Tenant in executing permit applications and performing other ministerial acts
reasonably necessary to enable Tenant to obtain any such permit or certificate of occupancy. No material changes, modifications or alterations in the Approved Working Drawings may be made without the prior written consent of Landlord (which consent
Landlord shall not unreasonably withhold, condition or delay). Tenant shall, however, have the right to request changes in the Approved Working Drawings from time to time, and Landlord shall within three (3) business days after each such
request, either approve such requested changes or reasonably disapprove such changes and deliver to Tenant written notice of the specific, reasonable modifications to Tenant’s proposed changes that Landlord requires for its reasonable approval.

 SECTION 4

(“Contractor”), subject to Landlord’s reasonable approval. Landlord approves Landmark Builders as the Contractor. 

4.1.2    Tenant’s Agents. All subcontractors, laborers, materialmen, and suppliers used by Tenant (such
subcontractors, laborers, materialmen, and suppliers, and the Contractor to be known collectively as “Tenant’s Agents”) shall be from a list supplied by Landlord or otherwise selected by Tenant, subject to Landlord’s
reasonable approval.

 4.3    Construction of Tenant Improvements by Tenant’s Agents.

 4.3.1    Construction Contract; Cost Budget. Prior to Tenant’s execution of the construction contract and
general conditions with Contractor (the “Contract”), Tenant shall submit the Contract to Landlord for its approval, which approval shall not be unreasonably withheld or delayed. Prior to the commencement of the construction of the Tenant
Improvements, and after Tenant has accepted all bids for the Tenant Improvements, Tenant shall provide Landlord with a detailed breakdown, by trade, of the final costs to be incurred or which have been incurred, as set forth more particularly in
Sections 2.4.1.1 through 2.4.1.10, above, in connection with the design and construction of the Tenant Improvements to be performed by or at the direction of Tenant or the Contractor, which costs form a basis for the
amount of the Contract (the “Final Costs”). In the event that the Final Costs are greater than the amount of the Tenant Improvement Allowance (the “Over-Allowance Amount”), then Tenant shall pay a percentage of each
amount requested by the Contractor or otherwise to be disbursed under this Tenant Work Letter, which percentage shall be equal to the Over-Allowance Amount divided by the amount of the Final Costs (after deducting from the Final Costs any amounts
expended in connection with the preparation of the Construction Drawings, and the cost of all other Tenant Improvement Allowance Items incurred prior to the commencement of construction of the Tenant Improvements), and such payments by Tenant (the
“Over-Allowance Payments”) shall be a condition to Landlord’s obligation to pay any amounts from the Tenant Improvement Allowance. In the event that, after the Final Costs have been delivered by Tenant to Landlord, the costs
relating to the design and construction of the Tenant Improvements shall change, any additional costs necessary to such design and construction in excess of the Final Costs, shall be added to the Over-Allowance Amount and the Final Costs, and the
Over-Allowance Payments shall be recalculated in accordance with the terms of the immediately preceding sentence. Notwithstanding anything set forth in this Tenant Work Letter to the contrary, construction of the Tenant Improvements shall not
commence until (a) Landlord has approved the Contract, and (b) Tenant has procured and delivered to Landlord a copy of all Permits. 

4.3.2    Tenant’s Agents. 

4.3.2.2    Landlord’s General Conditions for Tenant’s Agents and Tenant
Improvement Work. Tenant’s and Tenant’s Agent’s construction of the Tenant Improvements shall comply with the following: (i) the Tenant Improvements shall be constructed in accordance with the Approved Working Drawings and
Landlord’s rules and regulations for the construction of improvements in the Building, (ii) Tenant’s Agents shall submit schedules of all work relating to the Tenant’s Improvements to Landlord and Landlord shall, within five
(5) business days of receipt thereof, inform Tenant’s Agents of any changes which are necessary thereto, and Tenant’s Agents shall adhere to such corrected schedule; and (iii) Tenant shall abide by all reasonable rules made by
Landlord’s Building manager with respect to the use of freight, loading dock and service elevators, storage of materials, coordination of work with the contractors of other tenants, and any other matter in connection with this Tenant Work
Letter, including, without limitation, the construction of the Tenant Improvements. Landlord shall, however, provide Tenant and Tenant’s Agents, without charge, with reasonable access to, and use of, the freight loading dock and service
elevators during the construction of the Tenant Improvements, provided that, Tenant shall be required to pay to Landlord any reasonable costs associated with hiring a security guard if such usage occurs outside of normal business hours. Tenant shall
pay a logistical coordination fee (the “Coordination Fee”) to Landlord in an amount equal to three

percent (3%) of the hard construction costs of the Tenant Improvements, which Coordination Fee shall be for services relating to the coordination of the construction of the Tenant Improvements.
Tenant shall also be obligated to pay to Landlord any costs expended by Landlord in connection with the construction of the Tenant Improvements; provided, however, that in no event shall Tenant be required to reimburse Landlord for any work or
services performed by Landlord for or in connection with the Tenant Improvements, except for the reasonable and actual out-of-pocket cost incurred by Landlord, not to
exceed $10,000, in connection with any third-party review of the mechanical, electrical, plumbing, and/or structural portions, as applicable, of any construction drawings relating to the Tenant Improvements in the event that Tenant elects to make
alterations to the common mechanical, electrical, and plumbing systems serving the Building and/or the structure of the Building, as applicable. In the event of a conflict between the Approved Working Drawings and Landlord’s construction rules
and regulations, Landlord, in its reasonable discretion, shall determine which shall prevail. 

4.3.2.3    Indemnity. Tenant’s indemnity of Landlord as set forth in this Lease shall also apply with respect
to any and all costs, losses, damages, injuries and liabilities related in any way to any act or omission of Tenant or Tenant’s Agents, or anyone directly or indirectly employed by any of them, in connection with Tenant’s construction of
the Tenant Improvements and/or Tenant’s non-payment of any amount arising out of the Tenant Improvements (unless caused by Landlord’s failure to disburse funds from the Tenant Improvement Allowance
or the Additional Allowance in accordance with the terms of this Tenant Work Letter) and/or Tenant’s disapproval of all or any portion of any request for payment. Such indemnity by Tenant, as set forth in this Lease, shall also apply with
respect to any and all costs, losses, damages, injuries and liabilities related in any way to Landlord’s performance of any ministerial acts reasonably necessary (i) to permit Tenant to complete the Tenant Improvements, and (ii) to
enable Tenant to obtain any building permit or certificate of occupancy for the Premises, except to the extent caused by the negligence or willful misconduct of Landlord or any Landlord Parties or by Landlord’s breach of this Lease (including,
without limitation, this Tenant Work Letter). 
 4.3.2.4    Requirements of Tenant’s Agents. Each of
Tenant’s Agents shall guarantee to Tenant and for the benefit of Landlord that the portion of the Tenant Improvements for which it is responsible shall be free from any defects in workmanship and materials for a period of not less than one
(1) year from the date of completion thereof. Each of Tenant’s Agents shall be responsible for the replacement or repair, without additional charge, of all work done or furnished in accordance with its contract that shall become defective

additional expenses and damages incurred in connection with such removal or replacement of all or any part of the Tenant Improvements, and/or the Building and/or common areas that may be damaged or disturbed thereby. All such warranties or
guarantees as to materials or workmanship of or with respect to the Tenant Improvements shall be contained in the Contract or subcontract and shall be written such that such guarantees or warranties shall inure to the benefit of both Landlord and
Tenant, as their respective interests may appear, and can be directly enforced by either. Tenant covenants to give to Landlord any assignment or other assurances which may be necessary to effect such right of direct enforcement.

4.3.4    Inspection by Landlord. Tenant shall provide Landlord with reasonable prior notice of any inspection to be
performed by a governmental entity in connection with the construction of the Tenant Improvements in order to allow Landlord to be present during such inspection. Landlord shall have the right to inspect the Tenant Improvements at all times,
provided however, that Landlord’s failure to inspect the Tenant Improvements shall in no event constitute a waiver of any of Landlord’s rights hereunder nor shall Landlord’s inspection of the Tenant Improvements constitute
Landlord’s approval of the same. Should Landlord reasonably disapprove any portion of the Tenant Improvements, Landlord shall notify Tenant in writing of such reasonable disapproval and shall specify the items disapproved. Any defects or
deviations in, and/or disapproval by Landlord of, the Tenant Improvements shall be rectified by Tenant at no expense to Landlord, provided however, that in the event Landlord reasonably determines that a defect or deviation exists or reasonably
disapproves of any matter in connection with any portion of the Tenant Improvements and such defect, deviation or matter might adversely affect the mechanical, electrical, plumbing, heating, ventilating and air conditioning or life-safety systems of
the Building, the structure or exterior appearance of the Building or any other tenant’s use of such other tenant’s leased premises, Landlord may, take such action as Landlord reasonably deems necessary, at Tenant’s expense and
without incurring any liability on Landlord’s part, to correct any such defect, deviation and/or matter, including, without limitation, causing the cessation of performance of the construction of the Tenant Improvements until such time as the
defect, deviation and/or matter is corrected to Landlord’s reasonable satisfaction. 
 4.3.5    Meetings.
Commencing upon the execution of this Lease, Tenant shall hold weekly meetings at a reasonable time, with the Architect and the Contractor regarding the progress of the preparation of Construction Drawings and the construction of the Tenant
Improvements, which meetings shall be held at the Premises or by conference call, and Landlord and/or its agents shall receive prior notice of, and shall have the right to attend, all such meetings, and, upon Landlord’s reasonable request,
certain of Tenant’s Agents shall attend such meetings. In addition, minutes shall be taken at all such meetings, a copy of which minutes shall be promptly delivered to Landlord. One such meeting each month shall include the review of
Contractor’s current request for payment. 
 4.4    Notice of Completion; Copy of Record Set of Plans.

Section 3093 of the Civil Code of the State of California or any successor statute, and shall furnish a copy thereof to Landlord upon such recordation. If Tenant fails to do so, Landlord may execute and file the same on behalf of Tenant as
Tenant’s agent for such purpose, at Tenant’s sole cost and expense. At the conclusion of construction, (i) Tenant

default as described in the Lease or this Tenant Work Letter (beyond applicable notice and cure periods) has occurred at any time on or before the Substantial Completion of the Premises, then (i) in addition to all other rights and remedies
granted to Landlord pursuant to this Lease, Landlord shall have the right to withhold payment of all or any portion of the Tenant Improvement Allowance and/or Landlord may cause Contractor to cease the construction of the Premises (in which case,
Tenant shall be responsible for any delay in the substantial completion of the Premises caused by such work stoppage), and (ii) all other obligations of Landlord under the terms of this Tenant Work Letter shall be forgiven until such time as
such default is cured pursuant to the terms of this Lease (in which case, Tenant shall be responsible for any delay in the substantial completion of the Premises caused by such inaction by Landlord). 

5.4    Substantial Completion. For purposes of this Lease, “Substantial Completion” (i) of
the Tenant Improvements shall occur upon the completion of construction of the Tenant Improvements pursuant to the Approved Working Drawings, with the exception of any punch list items (the correction or completion of which will not materially

forth in such notice, shall be deemed to have occurred commencing as of the date such notice is received and continuing for the number of days the Substantial Completion of the Tenant Improvements was in fact delayed as a direct result of such
action or inaction. 
 5.6    Landlord Delay. The term “Landlord Delay” as used in the Lease or this
Tenant Work Letter shall mean any actual delay in the Substantial Completion of the Tenant Improvements caused by a (1) delay in the giving of authorizations or approvals by Landlord required by Landlord hereunder; (2) delay attributable

RULES AND REGULATIONS 

Tenant shall faithfully observe and comply with the following Rules and Regulations. Landlord shall not be responsible to Tenant for the
nonperformance of any of said Rules and Regulations by or otherwise with respect to the acts or omissions of any other tenants or occupants of the Project; provided, however, that Landlord will exercise good faith efforts (without any obligation to
place a tenant in default or commence litigation) to enforce the Rules and Regulations against other tenants and occupants of the Project in a nondiscriminatory manner. In the event of any conflict between the Rules and Regulations and the other
provisions of this Lease, the latter shall control. 
 1.    Signs. Except as specifically provided in this Lease
to which these rules and regulations are attached, no sign, placard, picture, advertisement, name or notice shall be installed or displayed on any part of the outside or inside of the Building or on the Common Areas or other areas of the Project
without Landlord’s prior written consent. Landlord may remove, at Tenant’s expense and without notice, any sign installed or displayed in violation of this rule. All signs or lettering on doors and walls must be approved by Landlord, and
shall be printed, painted, affixed or inscribed or modified at Tenant’s expense by a person approved by Landlord. Without Landlord’s written consent, Tenant shall not use the name of the Building or the Project in connection with or in
promoting or advertising the business of Tenant except as Tenant’s address. 
 2.    Window Treatments.
Tenant shall not place anything against or near glass partitions or doors or windows which may appear unsightly from outside the Premises. Tenant shall be held responsible for any damage to the glass coating within the Premises. If Landlord objects
in writing to any curtains, blinds, shades, screens or hanging plants or other similar objects attached to or used in connection with any window or door of the Premises, or placed on any windowsill, which are visible from the exterior of the
Premises, Tenant shall immediately discontinue such use. 
 3.    Common Areas. The sidewalks, entrances, halls,
corridors, elevators and stairways of the Building and the Project shall not be obstructed or used as a waiting or lounging place by Tenant and the Tenant’s Parties. All entrance doors leading from the Premises to the hallways are to be kept
closed at all times. The outside areas immediately adjoining the Premises shall be kept clear at all times by Tenant, and Tenant shall not place or permit any obstructions, garbage, refuse, merchandise or displays in such areas. The halls, passages,
exits, entrances, elevators, escalators and stairways are not open to the general public, but are open, subject to reasonable regulations, to Tenant’s Parties. Landlord shall, in all cases, retain the right to control and prevent access thereto
of all persons whose presence in the judgment of Landlord would be prejudicial to the safety of the Project or any part thereof provided that nothing herein contained shall be construed to prevent such access to persons with whom any tenant normally
deals in the ordinary course of its business, unless such persons are engaged in illegal or unlawful activities. Neither Tenant nor any Tenant Parties shall go upon the roof of the Building.

additional lock or bolt on any door of its Premises. Tenant, upon the termination of its tenancy, shall deliver to Landlord the keys to all doors and pay Landlord for any lost keys.

comply with Landlord’s instructions for their installation. 
 8.    Freight Elevators. The Building service
elevator shall be available for use by all tenants in the Building, subject to such reasonable scheduling by Landlord. No equipment, materials, furniture, packages, supplies, merchandise or other property will be received in the Building or carried

items shall be made after obtaining Landlord’s written consent and shall be made during the hours of 12:00 a.m. to 5:00 a.m. and 6:00 p.m. to 11:59 p.m., Monday through Friday, or at any time on Saturday or Sunday, unless
otherwise agreed in writing by Landlord. Deliveries during normal office hours shall be limited to normal office supplies and other small items. No deliveries shall be made which impede or interfere with other tenants or the operation of the
Building. 
 9.    Floor Load. Tenant shall not place a load upon any floor of the Premises which exceeds the
load per square foot which such floor was designed to carry and which is allowed by law. Prior to delivery of any heavy object to the Building, Tenant shall notify Landlord of such object’s specifications and contemplated location in order that
Landlord may take action to prevent structural load damage to the Building. Landlord shall have the right to prescribe the weight, size and position of all equipment, materials, furniture or other property brought into the Building. Heavy objects

such degree as to be objectionable to Landlord or to any tenants in the Building, shall be placed and maintained by Tenant, at Tenant’s sole cost and expense, on vibration eliminators or other devices sufficient to

(a) close and lock the doors of its Premises, (b) shut off all water faucets and other utilities, (c) draw or lower window coverings, and (d) turn out all lights. Tenant shall be responsible for any damage or injuries sustained
by other tenants or occupants of the Building or by Landlord for noncompliance with this rule.

 24.    Waiver. Landlord may waive any one or more of these Rules and
Regulations for the benefit of Tenant or any other tenant, but no such waiver by Landlord shall be construed as a waiver of such Rules and Regulations in favor of Tenant or any other tenant, nor prevent Landlord from thereafter enforcing any such

 25.    Integration. These Rules and
Regulations are in addition to, and shall not be construed to in any way modify or amend, in whole or in part, the terms, covenants, agreements and conditions of the Lease. 

26.    Additional Regulations. Landlord reserves the right to make such other and reasonable rules and regulations
as, in its judgment, may from time to time be needed for safety and security, for care and cleanliness of the Project of any part thereof and for the preservation of good order therein. Tenant agrees to abide by all such Rules and Regulations
hereinabove stated and any additional rules and regulations which are adopted and delivered to Tenant in writing. 

27.    Observance of Rules. Tenant shall be responsible for the observance of all of the foregoing rules by
Tenant’s employees, agents, clients, customers, invitees, licensees and guests. 
 28.    Parking
Facilities. The following rules and regulations shall govern use of the parking facilities within the Common Areas appurtenant to the Project (such parking facilities being collectively referred to hereinafter as the “Parking Area”).

 28.1    Persons using the Parking Area shall obey all signs and shall park only in areas designated for vehicle
parking within painted stall lines. Tenant’s parking spaces shall be used only for parking vehicles no longer than full-sized passenger automobiles. Tenant shall not permit any vehicle that belongs to or
is controlled by Tenant, its agents, employees, invitees, licensees and visitors, to be loaded, unloaded or parked in areas other than those designated by Landlord or its parking operator for such activities. No maintenance, washing, waxing or
cleaning of vehicles shall be permitted in the Parking Area. Unless otherwise instructed, each person using the Parking Area shall park and lock his or her own vehicle. Neither Landlord nor its parking operator shall be liable for damage to any
vehicle, injury to any person or loss of any property, all of which risks are assumed by the person using the Parking Area. Parking pursuant to this Lease is intended as a license only, and no bailment is intended or created hereby. No overnight or
extended term storage of any vehicles or other object shall be permitted; provided, however, that overnight parking by employees of Tenant shall be permitted during periods of business travel if Tenant submits to Landlord Landlord’s standard
request form in accordance with Landlord’s reasonable procedure. 
 28.2    Persons using the Parking Area shall
comply with any parking identification system established by Landlord or its parking operator. Such a system may include the validation of visitor parking, at the validation rate applicable to visitor parking from time to time as set by Landlord or

Landlord and declared void. Upon the loss or obliteration of a parking identification device, Tenant shall pay such reasonable replacement charge as may be established by Landlord or its parking
operator. Upon the termination of parking privileges, all parking identification devices supplied by Landlord shall be returned to Landlord. Landlord may refuse the sale of monthly stickers or other parking identification devices to any tenant or
person and/or his agents or representatives who willfully refuse to comply with these Rules and Regulations and all unposted city, state or federal ordinances, laws, or agreements. Loss or theft of parking identification devices from automobiles
must be reported to the garage manager immediately, and a lost or stolen report must be filed by the customer at that time. Landlord may exclude any car from the parking facilities that does not have an identification device. Any parking
identification devices reported lost or stolen found on any unauthorized car will be confiscated and the illegal holder will be subject to prosecution. Lost or stolen devices found by the purchaser must be reported to the parking facility office
immediately to avoid confusion. 
 28.3    The speed limit within all parking areas shall be five (5) miles per
hour. 
 28.4    Landlord reserves the right to modify, redesign or redesignate uses permitted in the Parking Area or
any portion thereof, to relocate parking spaces from floor to floor, from one portion of the Parking Area to another or to reasonably adjacent offsite locations, and to allocate parking spaces between compact and standard sizes from time to time, as
long as the same comply with applicable laws and ordinances. Reserved parking spaces shall be clearly and prominently marked as such by Landlord. But neither Landlord nor its parking operator shall be liable or responsible for the failure of persons
to observe such markings or to obey other rules and regulations, agreements, laws or ordinances applicable to the Parking Area. Without limiting the generality of the foregoing, Landlord shall not be obligated to tow any violator’s vehicle, or
to declare a default under or terminate the lease of any other tenant of the Building, on account of any such failure. If for any reason Landlord is unable to provide to Tenant all or any portion of its parking spaces or Tenant is unreasonably
denied access thereto during the initial term of this Lease or any renewal or extension hereof, such fact shall not be a default by Landlord or permit Tenant to terminate this Lease, either in whole or in part, but Tenant’s obligation (if any)
to pay rental for any parking space which is not provided by Landlord shall be abated for so long as Tenant does not have the use of such parking space, in full settlement of all claims that Tenant might otherwise have against Landlord by reason of
Landlord’s failure or inability to provide Tenant with such parking space. 
 Tenant shall be responsible for the compliance with all of the foregoing
rules and regulations by Tenant and Tenant Parties. Landlord may refuse to permit any person who violates any such reasonable rules and regulations to have access to the Project or any part thereof. Landlord reserves the right from time to time to
modify the rules and regulations set forth herein, including, without limitation, to adopt and modify such rules and regulations applicable to the Parking Area, as it deems necessary for the proper operation.

STANDARDS FOR UTILITIES AND SERVICES 

1.    Elevators. Provide non-attended passenger elevators to and from the
floor(s) on which the Premises are located. Landlord may limit the number of elevators operating outside normal business hours. 

2.    HVAC. On Monday through Friday, except holidays, from 7:00 a.m. to 6:00 p.m., ventilate the
Premises and furnish air conditioning or heating on such days and hours, in temperatures and amounts which in Landlord’s good faith judgment are reasonably required for comfortable occupancy of the Premises under normal business operations. If
Tenant requires air conditioning during other hours, Landlord will furnish same through an access system provided to Tenant at the Premises, if available, or otherwise as specified in a written request of Tenant delivered to the Building management
office before noon on the preceding business day. For this service Tenant will pay Landlord, upon receipt of Landlord’s statement, the charge at an hourly rate determined by Landlord from time to time, which is currently $244.71 for full HVAC
and $117.12: for fans only per hour. Tenant agrees that neither Tenant nor any Tenant Party shall at any time enter mechanical installations or facilities of the Building or adjust, tamper with, touch or otherwise in any manner affect said
installations or facilities. The cost of maintenance and service calls to adjust and regulate the air conditioning system shall be charged to Tenant if the need for maintenance work results from either Tenant’s adjustment of room thermostats or
Tenant’s failure to comply with Landlord’s rules governing the temperature within the Premises. 

3.    Lighting. Furnish electric lighting for all public areas and special service areas of the Building as
Landlord determines in good faith to be reasonable and standard, including replacement of Building standard lights, bulbs and tubes. 

4.    Electrical Service. Subject to the limitation of this Paragraph 4, furnish electrical service to the
Premises, including providing and installing all Building standard replacement lighting tubes. If Tenant uses more electrical power than Landlord in good faith considers reasonable or normal for office use, Tenant will pay Landlord on a monthly
basis the cost of such excess power consumed by Tenant. Consumption will be determined, at Landlord’s election, either (a) by a survey performed by a reputable consultant selected by Landlord, or (b) through separate meters or
submeters installed, maintained and read by Landlord at Tenant’s cost. For purposes of this Paragraph 4 only, “month” and “monthly” shall mean any billing period used by the utility or other power provider supplying
electricity. If Tenant’s installations of electrical fixtures, appliances and equipment within the Premises adversely affect the temperature or humidity otherwise maintained, Landlord may, at Tenant’s sole cost and expense (to be paid
within (30) days after delivery of written demand supported by invoices or other reasonably satisfactory evidence), install supplemental air conditioning units. Tenant’s use of electricity shall never exceed Tenant’s share of the
capacity of existing feeders to the Building or of the risers, wiring installations and transformers serving the floor(s) containing the Premises. Landlord shall provide not less than 3.5 watts per usable square foot (demand) of riser and floor

panel electrical capacity averaged over the floor being serviced. Landlord shall provide access to not less than 200 amps of electrical capacity in the Building electric room on the floor on
which the Premises is located. Tenant shall be responsible for installing additional electrical capacity from the Building electrical system in such Building electric room to the Premises for use with any information technology or server room
installed by Tenant. Tenant shall be allocated an approximate 2.0 watts per usable square foot for power and 1.5 watts per usable square foot for lighting. Any risers or wiring necessary to meet Tenant’s excess electrical requirements will be
installed by Landlord on Tenant’s request, at Tenant’s sole cost and expense (to be paid in advance), but only if in Landlord’s good faith belief they are necessary and will not cause damage to the Building or a dangerous condition,
entail excessive or unreasonable alterations, repairs or expense, or disturb other occupants. 
 5.    Water.
Provide toilet facilities, water for lavatory and toilet purposes, cold water for drinking and tepid water for lavatory purposes, all at points of supply provided for general use of tenants in the Building through fixtures installed by Landlord or
by Tenant with Landlord’s consent. 
 6.    Janitorial. Provide janitorial service to the Premises on
business days and other cleaning services as Landlord determines to be reasonably required. Tenant will pay Landlord the full cost attributable to any extraordinary janitorial or cleaning services which the Premises may require. 

7.    Maintenance of Non-Building Standard Items. Maintenance and service
