 2.5 Holding Over. 
 If Tenant holds

(102%) of the rental and otherwise upon the terms herein specified for the period immediately prior to such holding over and shall continue in such status until the tenancy is terminated by either party upon not less than one hundred twenty
(120) days prior written notice. If Tenant holds possession of the Premises or any portion thereof after the Term of this Lease without Landlord’s written consent, then Landlord in its sole discretion may elect (by written notice to
Tenant) to have Tenant become a tenant either from month to month or at will, at one hundred fifty percent (150%) of the rental (prorated on a daily basis for an at-will tenancy, if applicable) and otherwise upon the terms herein specified for
the period immediately prior to such holding over, or may elect to pursue any and all legal remedies available to Landlord under applicable law with respect to such holding over by Tenant. Tenant shall indemnify and hold Landlord harmless from any
loss, damage, claim, liability, cost or expense (including reasonable attorneys’ fees) resulting from any delay by Tenant in surrendering the Premises or any portion thereof (except to the extent such delay is with Landlord’s prior written
consent), including, but not limited to, any claims made by a succeeding tenant by reason of such delay. Acceptance of rent by Landlord following expiration or termination of this Lease shall not constitute a renewal of this Lease. 
 2.6 Options To Extend Term. 
 Tenant
shall have the option to extend the Term of this Lease for Phase 1A and Phase 1B only (but not Phase 2A), at the Minimum Rental set forth in Section 3.1(b) and (c), below, and otherwise upon all the terms and provisions set forth herein with
respect to the initial term of this Lease, for up to two (2) additional periods of ten (10) years each, the first commencing upon the expiration of the initial term hereof and the second commencing upon the expiration of the first extended
term, if any. Exercise of such option with respect to the first such extended term shall be by written notice to Landlord at least eighteen (18) months prior to the expiration of the initial term hereof, exercise of such option with respect to
the second extended term, if the first extension option has been duly exercised, shall be by written notice to Landlord at least eighteen (18) months prior to the expiration of the first extended term hereof. If Tenant is in material default
hereunder, beyond any applicable notice and cure periods, on the date of such notice or on the date any extended term is to commence, then the exercise of the option shall be of no force or effect, the extended term shall not commence and this Lease
shall expire at the end of the then current term hereof (or at such earlier time as Landlord may elect pursuant to the default 

  

 6 

 
provisions of this Lease). If Tenant properly exercises one or more extension options under this Section, then all references in this Lease (other than in
this Section 2.6) to the “term” of this Lease shall be construed to include the extension term(s) thus elected by Tenant. Except as expressly set forth in this Section 2.6, Tenant shall have no right to extend the Term of this
Lease beyond its prescribed term. 
 3. RENTAL. 
 Tenant shall cause payment of Minimum Rental and other rent or charges to be received by Landlord on the first calendar day of each month of the Term of this Lease in lawful money of the United States, without offset or deduction, except as
specifically provided herein. All amounts payable by Tenant hereunder shall be deemed “Rent.” 
 3.1 Minimum Rental.

 (a) Commencement of Rental Obligations for Phase 1. 
 Tenant’s Minimum Rental obligations with respect to Phase 1A and Phase 1B shall commence on the Phase 1 Rent Commencement Date and Tenant’s
Operating Expense Obligations with respect to Phase 1A and Phase 1B shall commence as of the Effective Date, and both shall end on the Building 1 Termination Date, unless sooner terminated or extended as hereinafter provided. 
 (b) Commencement of Rental Obligations for Phase 2A. 
 Tenant’s Minimum Rental obligations with respect to Phase 2A shall commence on the Effective Date and Tenant’s Operating Expense obligations with respect to Phase 2A shall commence as of the Effective Date
and both shall end on the Building 2 Termination Date, unless sooner terminated as hereinafter provided. 
 (c) Rental Amounts for Phase
1A, Phase 1B; and Phase 2A: Annual Increases. 
 Tenant shall pay to Landlord as minimum rental for the following Phases, in advance,
without deduction, offset, notice or demand, on or before the respective Rent Commencement Date and on or before the first day of each subsequent calendar month of the Term of this Lease, the following amounts per month, subject to adjustment in
accordance with the terms of this Section 3.1 (“Minimum Rental”): 
 (i) Phase 1A and 1B. Beginning on the Phase
1 Rent Commencement Date, Tenant shall pay Minimum Rental for Phase 1 in an amount equal to $287,701.20 ($3.60 per sq. ft. multiplied by 79,917). 
 (ii) Phase 2A. Beginning on the Phase 2A Rent Commencement Date, Tenant shall pay Minimum Rental for Phase 2A in an amount equal to $164,066.40 ($3.60 per sq. ft. multiplied by 45,574). 
 (iii) [Deleted]. 
  

 7 

 (iv) Annual Increases. On the anniversary of each of October 6 of each year (as to the Phase
1 Rent) and October 6 of each year (as to the Phase 2A Rent), the then current Minimum Rental for the relevant Phase shall be increased by two percent (2%). 
 (v) Partial Months. If the obligation to pay Minimum Rental hereunder commences on other than the first day of a calendar month or if the Term of this Lease terminates on other than the last day of a calendar
month, the Minimum Rental for such first or last month of the Term of this Lease, as the case may be, shall be prorated based on the number of days the Term of this Lease is in effect during such month. If an increase in Minimum Rental becomes
effective on a day other than the first day of a calendar month; the Minimum Rental for that month shall be the sum of the two applicable rates, each prorated for the portion of the month during which such rate is in effect. 
 (d) Rental Amounts During First Extended Term. 
 If Tenant properly exercises its right to extend the Term of this Lease pursuant to Section 2.6 hereof, the Minimum Rental during the first year of the first extended term shall be equal to one hundred percent
(100%) of the fair market rental value (as defined below), determined as of the commencement of such extended term in accordance with this paragraph. Upon Landlord’s receipt of a proper notice of Tenant’s exercise of its option to
extend the Term of this Lease, the parties shall have thirty (30) days in which to agree on the Fair Market Rental at the commencement of the first extended term for the uses permitted hereunder. If the parties agree on such Fair Market Rental,
they shall execute an amendment to this Lease stating the amount of the applicable minimum monthly rental (including the indexed amounts applicable during subsequent years of the first extended term as described above in Section 3.l(c)(iv)). If
the parties are unable to agree on such rental within such thirty (30) day period, then within thirty (30) days after the expiration of such period each party, at its cost and by giving notice to the other party, shall appoint a real
estate appraiser with at least five (5) years experience appraising similar commercial properties in the County in which the Real Property is located to appraise and set the Fair Market Rental for the Premises at the commencement of the first
extended term in accordance with the provisions of this Section 3. l(d). If either party fails to appoint an appraiser within the allotted time, the single appraiser appointed by the other party shall be the sole appraiser. If an appraiser is
appointed by each party and the two appraisers so appointed are unable to agree upon a Fair Market Rental within thirty (30) days after the appointment of the second, the two appraisers shall appoint a third similarly qualified appraiser within
ten (10) days after expiration of such 30-day period; if they are unable to agree upon a third appraiser, then either party may, upon not less than five (5) days notice to the other party, apply to the Presiding Judge of the Superior Court
of the County in which the Real Property is located for the appointment of a third qualified appraiser. Each party shall bear its own legal fees in connection with appointment of the third appraiser and shall bear one-half of any other costs of
appointment of the third appraiser and of such third appraiser’s fee. The third appraiser, however selected, shall be a person who has not previously acted for either party in any capacity. Within thirty (30) days after the appointment of
the third appraiser, the third appraiser shall set the Fair Market Rental for the first extended term by selecting the appraised value determined by the first two appraisers which is closest to his own determination, and shall so notify the parties,
which determination shall be binding on the parties and shall be enforceable in any further proceedings relating to this Lease. For purposes of this Section 3.1(d), the “Fair Market Rental” of the 

  

 8 

 
Premises shall be determined with reference to the then prevailing market rental rates for properties in the City of San Carlos with improvements and common
area improvements comparable to those then existing in the Premises and paid for by Landlord. 
 (e) Rental Amounts During Second Extended
Term. 
 If Tenant properly exercises its right to a second extended Term of this Lease pursuant to Section 2.6 hereof, the Minimum
Rental during such second extended term shall be determined in the same manner provided in the preceding paragraph for the first extended term (including the rental increase provision for years after the first year of such second extended term),
except that the determination shall be made as of the commencement of the second extended term. 
 3.2 Late Charge. 
 If Tenant shall fail to pay, when the same is due and payable (after giving effect to any applicable notice and cure period), any rent or other amounts
due Landlord hereunder, such unpaid amounts shall bear interest for the benefit of the Landlord at a rate equal to the lesser of ten percent (10%) per annum or the maximum rate permitted by law, from the date due to the date of payment. Tenant
further acknowledges that late payment of rent will cause Landlord to incur certain costs not contemplated by this Lease, the exact amount of such costs being extremely difficult and impractical to determine with certainty. For this reason, in
addition to interest, if Tenant shall fail to pay (which for purposes of this paragraph, “pay” shall mean actual receipt of the payment by Landlord) any installment of rent by the fifth (5th) day of the calendar month for which such
installment is due, a late charge equal to five percent (5%) of the overdue installment of rent automatically shall be due without further notice, and shall be in addition to all other sums due. The parties agree that this additional late
charge represents a fair and reasonable estimate of the costs Landlord will incur by reason of late payment by Tenant 
 4. PARKING. 
 Landlord and Tenant agree that the Common Areas of the Real Property shall include not less than 690 parking spaces. Commencing on the Effective Date and
ending on the Building 2 Termination Date, Tenant shall be entitled to 361 spaces, and commencing on the Building 2 Termination Date and ending on the Building 1 Termination Date, Tenant shall be entitled to 224 spaces, all in addition to those
spaces provided in and subject to the Parking Lease. 
 5. CONSTRUCTION. 
 5.1 Construction of Improvements. 
 (a) Base Building Work: Performance and Payment.

 Landlord has constructed Building 1 and Building 2 pursuant to its obligations under the Original Lease and Landlord and Tenant agree,
subject to Section 5.1(c) below, that Landlord’s obligations in connection with such construction have been fully and satisfactorily performed. 
  

 9 

 (b) Tenant’s Work; Phase 2A Improvements. 
 Tenant has constructed Tenant Improvements within Phase 1A Phase 1B of the Premises in accordance with the prior lease, and may make such future
improvements and modifications to the same as set forth herein. Tenant and Landlord agreed under the Original Lease to provide Tenant with a Tenant improvement Allowance for tenant improvements within each Phase of the Premises equal to $100 per
Usable Square Foot. Tenant and Landlord agree that this obligation has been satisfied as to Phase 1, and further agree Landlord shall construct improvements to Phase 2A pursuant to that Work Letter attached hereto as Exhibit C, and that such
improvements constructed pursuant to the Work Letter shall meet Landlord’s obligations as to $70 per Usable Square Foot of Phase 2A, or such higher amount per Usable Square Foot actually expended by Landlord in constructing improvements within
Phase 2A. 
 (c) Compliance with Law. 
 Landlord warrants to Tenant that the Base Building Work and any other improvements constructed by Landlord from time to time shall not violate any applicable law, building code, regulation or ordinance in effect on
the applicable Rent Commencement Date or at the time such improvements are placed in service. If it is determined that any of these warranties have been violated, then it shall be the obligation of the Landlord, after written notice from Tenant, to
correct the conditions(s) constituting such violation promptly, at Landlord’s sole cost and expense. 
 6. TAXES. 
 6.1 Personal Property. 
 Tenant shall
be responsible for and shall pay prior to delinquency all taxes and assessments levied against or by reason of (a) any and all alterations, additions and items installed or placed on or in the Premises and taxed as personal property rather than
as real property, and/or (b) all personal property, trade fixtures and other property placed by Tenant on or about the Premises. Upon request by Landlord, Tenant shall furnish Landlord with satisfactory evidence of Tenant’s payment
thereof. If at any time during the Term of this Lease any of said alterations, additions or personal property, whether or not belonging to Tenant, shall be taxed or assessed as part of the Real Property, then such tax or assessment shall be paid by
Tenant to Landlord within thirty (30) days after presentation by Landlord of copies of the tax bills in which such taxes and assessments are included and shall, for the purposes of this Lease, be deemed to be personal property taxes or
assessments under this Section 6.1. 
 6.2 Real Property Taxes. 
 (a) Real Property Taxes. 
 Commencing
with the Effective Date and continuing for each calendar year, or tax year at Landlord’s option (such “tax year” being a period of twelve (12) consecutive calendar months for which the applicable taxing authority levies or
assesses real property taxes), for the balance of the Lease Term, Tenant shall pay to Landlord the Tenant’s Operating Cost Share of all real property taxes, pursuant to Section 7.2(a) below. Such sum for any partial year of the Lease Term
shall be prorated on the basis of the number of days of such partial year. Landlord also shall provide Tenant with a copy of the applicable tax bill or tax statement from the taxing 

  

 10 

 
authority. In addition to any other amounts due from Tenant to Landlord, if Tenant fails to pay the real property taxes to Landlord as herein required,
Tenant shall pay to Landlord the amount of any interest, penalties or late charges caused by Tenant’s late payment. 
 (b)
Protests. 
 If the Premises are separately assessed, Tenant shall have the right, by appropriate proceedings, to protest or contest in
good faith any assessment or reassessment of real property taxes, any special assessment, or the validity of any real property taxes or of any change in assessment or tax rate; provided, however, that prior to any such challenge Tenant must
either (a) pay the taxes alleged to be due in their entirety and seek a refund from the appropriate authority, or (b) post bond in an amount sufficient to insure full payment of the real property taxes. In any event, upon a final
determination with respect to such contest or protest, Tenant shall promptly pay all sums found to be due with respect thereto. In any such protest or contest, Tenant may act in its own name, and at the request of Tenant, Landlord shall cooperate
with Tenant in any way Tenant may reasonably require in connection with such contest or protest, including signing such documents as Tenant reasonably shall request, provided that such cooperation shall be at no expense to Landlord and shall not
require Landlord to attend any appeal or other hearing. Any such contest or protest shall be at Tenant’s sole expense, and if any penalties, interest or late charges become payable with respect to the real property taxes as a result of such
contest or protest, Tenant shall pay the same. 
 (c) Refunds. 
 If Tenant obtains a refund as the result of Tenant’s protest or contest and subject to Tenant’s obligation to pay Landlord’s costs (if any)
associated therewith, Tenant shall be entitled to such refund to the extent it relates to Phase 1 or Phase 2A (to the extent occupied by Tenant) of the Premises during the Lease Term. 
 (d) Other Taxes. 
 If at any time
during the Lease Term under the laws of the United States Government, state, county or city, or any political subdivision thereof in which the Premises are situated, a tax or excise on rent or any other tax however described is levied or assessed by
any such political body against Landlord on account of rentals payable to Landlord hereunder, such tax or excise shall be considered “real property taxes” for the purposes of this Section 6.2, excluding, however, from such tax or
excise any amount assessed against Landlord as state or federal income tax. 
 (e) Tax and Insurance Escrows. 
 To the extent required by any lender of Landlord, Tenant shall timely pay all tax and insurance impound payments due on the Premises. 
  

 11 

 7. OPERATING EXPENSES. 
 7.1 Payment of Operating Expenses. 
 (a) Tenant’s Operating Cost Share. 
 (i) Commencing on the Effective Date through the Building 1 Termination Date or the Building 2 Termination Date, as applicable, Tenant shall pay to
Landlord, at the time and in the manner hereinafter set forth, as additional rental: (i) an amount equal to Tenant’s Operating Cost Share multiplied by the Operating Expenses defined in Section 7.2, and (ii) an amount equal to
Tenant’s Operating Cost Share multiplied by the Exterior Common Area Cost. 
 (ii) [Deleted]

 7.3 Determination of Operating Expenses. 
 During the last month of each calendar year of the Term of this Lease (“Lease Year”), or as soon thereafter as practical, Landlord shall provide Tenant notice of Landlord’s estimate of the Operating Expenses for the
ensuing Lease Year or applicable portion thereof. On or before the first day of each month during the ensuing Lease Year or applicable portion thereof, beginning on the Phase 1 Rent Commencement Date, Tenant shall pay to Landlord Tenant’s
Operating Cost Share of the portion of such estimated Operating Expenses allocable (on a pro rata basis) to such month; provided, however, that if such notice is not given in the last month of a Lease Year, Tenant shall continue to pay on the
basis of the prior year’s estimate, if any, until the month after such notice is given. If at any time or times it appears to Landlord that the actual Operating Expenses will vary from Landlord’s estimate by more than four percent (4%),
Landlord may, by notice to Tenant, revise its estimate for such year and subsequent payments by Tenant for such year shall be based upon such revised estimate. 
 7.4 Final Accounting For Lease Year. 
 (a) Annual Statement. 
 Within ninety (90) days after the close of each Lease Year, or as soon after such 90-day period as practicable, Landlord shall deliver to Tenant a
statement of Tenant’s Operating Cost Share of the Operating Expenses for such Lease Year prepared by Landlord from Landlord’s books and records, which statement shall be final and binding on Landlord and Tenant (except as provided in
Section 7.4(b)). If on the basis of such statement Tenant owes an amount that is more or less than the estimated payments for such Lease Year previously made by Tenant, Tenant or Landlord, as the case may be, shall pay the deficiency to the
other party within thirty (30) days after delivery of the statement. Failure or inability of Landlord to deliver the annual statement within such ninety (90) day period shall not impair or constitute a waiver of Tenant’s obligation to
pay Operating Expenses, or cause Landlord to incur any liability for damages. 
 (b) Audit Rights. 
 At any time within one hundred twenty (120) days after receipt of Landlord’s annual statement of Operating Expenses as contemplated in
Section 7.4(a), Tenant shall be entitled, upon reasonable written notice to Landlord and during normal business hours at Landlord’s office or such other places as Landlord shall designate, to inspect and examine those books and records of
Landlord relating to the determination of Operating Expenses for the immediately 

  

 15 

 
preceding Lease Year covered by such annual statement or, if Tenant so elects by written notice to Landlord, to request an independent audit of such books
and records. The independent audit of the books and records shall be conducted by a certified public accountant acceptable to both Landlord and Tenant or, if the parties are unable to agree, by a certified public accountant appointed by the
Presiding Judge of the County Superior Court in which the Real Property is located upon the application of either Landlord or Tenant (with notice to the other party). In either event, such certified public accountant shall be one who is not then
employed in any capacity by Landlord or Tenant. The audit shall be limited to the determination of the amount of Operating Expenses for the subject Lease Year, and shall be based on generally accepted accounting principles and tax accounting
principles, consistently applied. If it is determined, by mutual agreement of Landlord and Tenant or by independent audit, that the amount of Operating Expenses billed to or paid by Tenant for the applicable Lease Year was incorrect, then the
appropriate party shall pay to the other party the deficiency or overpayment, as applicable, within thirty (30) days after the final determination of such deficiency or overpayment. All costs and expenses of the audit shall be paid by Tenant
unless the audit shows that Landlord overstated Operating Expenses for the subject Lease Year by more than five percent (5%), in which case Landlord shall pay all costs and expenses of the audit. Each party agrees to maintain the confidentiality of
the findings of any such audit. 
 7.5 Proration. 
 If the Rent Commencement Date for Phase 1 or Phase 2A falls on a day other than the first day of a Lease Year and/or if the Building 1 Termination Date or the Building 2 Termination Date falls on a day other than the
last day of a Lease Year, then the amount of Operating Expenses payable by Tenant with respect to such first or last partial Lease Year shall be prorated on the basis which the number of days during such Lease Year in which this Lease is in effect
bears to 365. The termination of this Lease shall not affect the obligations of Landlord and Tenant pursuant to Section 7.4 to be performed after such termination. 
 7.6 Reserve Account. 
 Tenant shall each month, commencing on the Phase 1 Rent Commencement Date and
on the first day of each calendar month thereafter of the Lease term, deposit into a segregated, interest bearing bank account in a federally insured bank or savings institute an amount equal to one percent (1%) of the monthly rent due for that
month, to provide for future replacements to improvements and fixtures within the Premises (the “Reserve Account”); provided that if at any time the amount held in the Reserve Account is equal to the product of thirty six months
times the amount of the monthly contribution, Tenant’s obligation to make additional deposits shall be temporarily suspended. Tenant’s obligation to make such deposits shall resume at such time as the amount in the Reserve Account drops
below such amount. The Reserve Account shall remain the property of Tenant, but disbursements from the Reserve Account shall be made only by joint check executed by Landlord and Tenant upon the mutual consent of Landlord and Tenant, which consent
shall not be unreasonably withheld, delayed or conditioned. Landlord shall, within ten (10) days after receipt of a written request, either sign any such check or convey in writing to Tenant any objections to signing the check, and shall
thereafter diligently work with Tenant to resolve any differences with regard to the disbursement. Notwithstanding the foregoing, if Tenant, pursuant to the Lease, is required to make certain repairs, improvements, or 

  

 16 

 
replacements to the Premises or Common Area but fails to do so within the time allowed hereunder (subject to any applicable cure period), then Landlord, as
provided under the Lease, may make such repairs, improvements, or replacements, and may disburse funds from the Reserve Account, without Tenant’s consent or signature on the disbursement check(s), to pay for the cost of the repairs,
improvements, or replacements. Any amount in the Reserve Account remaining at the expiration of the Lease shall remain the property of Tenant. 
 7.7 Property Management Fee. 
 Commencing with the execution of this Lease, Tenant shall pay to Landlord a monthly fee
(“Management Fee”) to cover costs of property management services in an amount not to exceed one percent (1.00%) of the Minimum Rental for the Premises whether or not Landlord incurs fees payable to any third party to provide
such services and without regard to the actual costs incurred by Landlord for such services. 
 8. UTILITIES. 
 8.1 Payment. 
 Commencing with the
Phase 1 Rent Commencement Date and thereafter throughout the Term of this Lease, Tenant shall pay, before delinquency, all charges for water, trash collection, gas, heat, light, electricity, power, sewer, telephone, alarm system, janitorial and
other services or utilities supplied to or consumed in or with respect to the Premises, including any taxes on such services and utilities, and Tenant’s Operating Cost Share of all charges for water, gas, heat, light, electricity, power, sewer,
telephone, alarm system, janitorial and other services or utilities supplied to or consumed in or with respect to the Common Areas. It is the intention of the parties that to the extent feasible, all services provided to the Premises (as opposed to
the Common Areas and as the same shall exist from time to time) shall be separately metered to the Premises. 
 8.2 Interruption. 

 There shall be no abatement of rent or other charges required to be paid hereunder and Landlord shall not be liable in damages or otherwise
for interruption or failure of any service or utility furnished to or used with respect to the Premises because of accident, making of repairs, alterations or improvements, severe weather, difficulty or inability in obtaining services or supplies,
labor difficulties or any other cause, except the gross negligence or willful misconduct of Landlord, its employees and/or agents. 
 9. ALTERATIONS. 

 9.1 Right To Make Alterations. 
 Tenant shall make no alterations, additions or improvements to the Premises, other than interior non-structural alterations (“Cosmetic Alterations”) costing less than One Hundred Thousand Dollars ($100,000) in the aggregate
during any twelve (12) month period, without the prior written consent of Landlord, which consent shall not be unreasonably withheld, delayed or conditioned, and if Tenant so requests, Landlord shall specify whether Landlord intends to 

  

 17 

 
require that Tenant remove such Cosmetic Alterations (or any specified portions thereof) upon expiration or termination of this Lease. Landlord’s
failure to respond within fifteen (15) days of Tenant’s request or notice to Landlord shall be deemed Landlord’s consent to allow the Cosmetic Alterations to remain with the Premises at the end of the Lease Term. Tenant shall provide
to Landlord copies of any plans submitted to any governmental agency in connection with the construction of any Cosmetic Alterations, within thirty (30) days of such submittal. All alterations, additions and improvements shall be completed with
due diligence in a first-class, workmanlike manner, in compliance with plans and specifications approved in writing by Landlord and in compliance with all applicable laws, ordinances, rules and regulations, and to the extent Landlord’s consent
is not otherwise required hereunder for such alterations, additions or improvements, Tenant shall give prompt written notice thereof to Landlord. With respect to all proposed alterations (other than Cosmetic Alterations or otherwise), Tenant shall
provide Landlord with a cost estimate to perform the alterations, a set of plans and specifications for the proposed work, and a set of final “as built” plans of the work actually performed. Tenant shall cause any contractors engaged by
Tenant for work in the Buildings or on the Real Property to maintain public liability and property damage insurance, and other customary insurance, with such terms and in such amounts as Landlord may reasonably require, naming as additional insureds
Landlord and any of its partners, shareholders, property managers and lenders designated by Landlord for this purpose, and shall furnish Landlord with certificates of insurance or other evidence that such coverage is in effect. Notwithstanding any
other provisions of this Section 9.1, under no circumstances shall Tenant make any structural alterations or improvements, or any changes to the roof or equipment installations on the roof, or any substantial changes or alterations to the
building systems, except Cosmetic Alterations, without Landlord’s prior written consent (which consent shall not be unreasonably withheld, delayed or conditioned). Landlord’s failure to respond within fifteen (15) days following
Tenant’s request shall be deemed approval. Landlord shall receive no fee for supervision, profit, overhead or general conditions, but shall be entitled to be reimbursed by Tenant for any reasonable costs incurred by Landlord in connection with
its retention of third parties to assist in its review of Tenant’s request for consent in connection with any alterations, additions or improvements constructed or installed by Tenant under this Lease after the date hereof. 
 9.2 Title To Alterations. 
 All
alterations, additions and improvements installed in, on or about the Premises at Tenant’s expense shall belong to Tenant during the Lease Term and upon expiration or earlier termination shall become part of the Real Property and shall become
the property of Landlord, unless Landlord elects (at the time it grants consent to installation) to require Tenant to remove the same upon the termination of this Lease; provided, however, that the foregoing shall not apply to Tenant’s
movable furniture and equipment and trade fixtures. Tenant shall promptly repair any damage caused by its removal of any such alterations, additions and improvements, furniture, equipment or trade fixtures. Landlord shall not be entitled to require
removal unless Landlord specified its intention to do so at the time of granting of Landlord’s consent to the requested alterations, additions or improvements. Notwithstanding any other provisions of this Article 9, however, under no
circumstances shall Tenant have any obligation to remove from the Buildings or the Real Property, at the expiration or termination of this Lease, any of the Tenant Improvements constructed by Landlord. 
  

 18 

 9.3 Tenant Fixtures and Personal Property. 
 Subject to Section 9.2 and to Section 9.5, Tenant may install, remove and reinstall trade fixtures without Landlord’s prior written
consent, except that installation and removal of any fixtures which are affixed to the Buildings or the Real Property or which affect the exterior or structural portions of the Buildings or the building systems shall require Landlord’s written
approval, which approval shall not be unreasonably withheld, delayed or conditioned. 
 9.4 No Liens. 
 Tenant shall at all times keep the Premises free from all liens and claims of any contractors, subcontractors, materialmen, suppliers or any other parties
employed either directly or indirectly by Tenant in construction work on the Buildings or the Real Property. Tenant may contest any claim of lien, but only if, prior to such contest, Tenant either (i) posts security in the amount of the claim,
plus estimated costs and interest, or (ii) records a bond of a responsible corporate surety in such amount as may be required to release the lien from the Buildings and the Real Property no later than the thirtieth day following recordation of
such lien. Tenant shall indemnify, defend and hold Landlord harmless against any and all liability, loss, damage, cost and other expenses, including, without limitation, reasonable attorneys’ fees, arising out of claims of any lien for work
performed or materials or supplies furnished at the request of Tenant or persons claiming under Tenant. Tenant shall at no time voluntarily place any fixture filing or otherwise grant a security interest in any alterations, additions or improvements
installed in, on or about the Premises. 
 9.5 Signs. 
 Tenant shall have the right to a proportionate share of external and monument signage, in proportion to the ratio between the Useable Square Footage in Tenant’s Premises and the total Useable Square Footage on
the Real Property, provided however, Tenant shall have the right to continue to display its corporate name and logo on the exterior of the Buildings in the size and manner it is displayed as of the Effective Date (subject to changes in applicable
laws or regulations requiring a modification to such signage). 
 10. MAINTENANCE AND REPAIRS. 
 10.1 Tenant’s Obligation for Maintenance. 
 (a) Good Order, Condition and Repair. 
 (i) In addition to Tenant’s obligation to pay Tenant’s Operating Cost
Share as required by Section 7, Tenant’s repair and maintenance obligation shall be limited to the repair and maintenance of the interior of the Premises, as the same shall exist from time to time (being defined as the floor surfaces,
ceiling, interior wall surfaces, electrical, plumbing, HVAC equipment exclusively serving the Premises and telephone and communications systems within such interior).

sanitary order, in a first class condition and repair. In such case, immediately on demand from Landlord, the cost of such repairs shall be due and payable by Tenant to Landlord. 
 (d) Condition Upon Surrender. 
 At the
expiration or sooner termination of this Lease, Tenant shall surrender the Premises, including any additions, alterations and improvements thereto, broom clean, in good and sanitary order, in a first class condition and repair, free from Hazardous

wear and tear excepted, and delivered free of radioactive licenses or other restrictions on use, first, however, removing all goods and effects of Tenant and all fixtures and items required to be removed or specified to be removed at Landlord’s
election pursuant to this Lease, and repairing any damage caused by such removal. Tenant expressly waives any and all interest in any personal property and trade fixtures not removed from the Premises by Tenant at the expiration or termination of
this Lease, agrees that any such personal property and trade fixtures may, at Landlord’s election, be deemed to have been abandoned by Tenant, and authorizes Landlord (at its election and without prejudice to any other remedies under this Lease
or under applicable law) to remove and either retain, store or dispose of such property at Tenant’s cost and expense, and Tenant waives all claims against Landlord for any damages resulting from any such removal, storage, retention or disposal.

 20

portion of the Premises or Common Areas, or in or to improvements, fixtures, equipment and personal property therein. 
 (c)
Landlords’ Right of Entry for Repairs. 
 Landlord and Landlord’s agents shall have the right to enter upon the Premises, or
any part thereof, for the purpose of performing any repairs or maintenance Landlord is permitted to make pursuant to this Lease, and of ascertaining the condition of the Premises or whether Tenant is observing and performing Tenant’s

manufacture, occupation, odor or fumes, or any nuisance or anything against public policy, nor commit or allow to be committed any waste in, on or about the Premises. Tenant shall not do or permit anything to be done in or about the Premises, nor
bring nor keep anything therein, which will in any way cause the Premises to be uninsurable with respect to the insurance required by this Lease or with respect to standard fire and extended coverage insurance with vandalism, malicious mischief and
riot endorsements. 
 11.3 Compliance With Laws. 
 Tenant shall not use the Premises or permit the Premises to be used in whole or in part for any purpose or use that is in violation of any applicable laws, ordinances, regulations or rules of any governmental agency

 (vii) Tenant shall surrender the Premises

result of any intentional or negligent acts or omissions of Tenant or of any agent, employee, vendor or invitee of Tenant. 
 (d)
Survival. 
 The provisions of this Section 11.4 shall survive the termination of this Lease. 
 12. INSURANCE AND INDEMNITY. 
 12.1 Landlord’s
Insurance. 
 During the Lease Term, Landlord shall keep and maintain, or cause to be kept and maintained, as part of Operating Expenses,
a policy or policies of insurance on the Buildings insuring the same against loss or damage by the following risks: fire and extended coverage, vandalism, malicious mischief, sprinkler leakage (if sprinklers are required in the Buildings under
applicable building code provisions, or are installed by Tenant in the absence of such requirement) in amounts not less than ninety percent (90%) of Full Replacement Value of the Buildings, (including both the Buildings and any tenant
improvements), or the amount of such insurance Landlord’s lender requires Landlord to maintain. The term “Full Replacement Value” shall mean actual replacement cost, including changes required by new building codes or ordinances
(exclusive of the cost of excavation, foundations and footings). Such insurance shall show, as a loss payee in respect of the Premises, Landlord, Tenant and any ground lessor or mortgagee of Landlord required to be named pursuant to its mortgage
documents, as their interests may appear. Landlord, subject to availability thereof and, as part of Operating Expenses, shall further insure as Landlord deems appropriate coverage against flood, earthquake, environmental remediation, loss or failure
of building equipment, rental loss for a period of eighteen (18) months for periods of repair or rebuild, workmen’s compensation insurance and fidelity bonds for employees employed to perform services. Notwithstanding the foregoing,
Landlord may, but shall not be deemed required to, provide insurance as to any improvements installed by Tenant, provided that such coverage does not duplicate coverages maintained by Tenant. Landlord, as part of the Operating Expenses, shall
further carry General Liability with General Aggregate Amount & Per Occurrence Limit insurance with a single loss limit of not less than Five Million Dollars ($5,000,000) for death or bodily injury, or property damage with respect to the
Real Property. 
  

 24 

 12.2 Tenant’s Insurance. 
 (a) Commercial General Liability Insurance. 
 During the Lease Term, Tenant shall keep and maintain, or cause to be kept and maintained, at Tenant’s sole cost and expense, a policy or policies of Commercial General Liability insurance, showing, as an additional insured in respect
of the Premises, Landlord, Tenant, any management company retained by Landlord to manage the Premises, any ground lessor and any lender of Landlord required to be named pursuant to its loan documents. Such policy shall insure against any and all
claims, demands or actions for injuries to persons, loss of life and damage to property occurring upon, in or about the Premises (including coverage for liability caused by independent contractors of Tenant or subtenants of Tenant working in or
about the Premises), with minimum coverage in an amount not less than a Five Million Dollars ($5,000,000) combined single limit with respect to all bodily injury, death or property damage in any one accident or occurrence. In the event of a claim,
action or demand relating to the Premises, the amount of any deductible or self-insured retention and/or any award in excess of the policy limits shall be the sole responsibility of Tenant. 
 (b) Tenant’s Risk. 
 Tenant
assumes the risk of damage to any fixtures, goods, inventory, merchandise and equipment, and Landlord shall not be liable for injury to Tenant’s business or any loss of income therefrom relative to such damage except as more particularly
heretofore set forth within this Lease. Tenant at Tenant’s cost may carry such insurance as Tenant desires for Tenant’s protection with respect to personal property of Tenant, business interruption or other coverages. 
 (c) Other Insurance. 
 In addition to
all other insurance required to be carried by Tenant hereunder, Tenant, throughout the Lease Term, shall provide and keep in force at Tenant’s sole cost and expense the following: 
 (i) Workman’s Compensation insurance to the full extent required under the laws of the State of California; 
 (ii) Insurance on Tenant’s equipment, personal property and other contents in, on or about the Premises insuring against loss or damage by all risks
covered by “special form” coverage, in amounts equal to ninety percent (90%) of their full replacement value; 
 (iii)
[Deleted]; and 
 (iv) Other nonduplicative insurance required by Landlord, in types and amounts consistent with commercially reasonable
practice. 
  

 25 

 12.3 Insurers; Primary Insurance. 
 All policies of insurance provided for herein shall be on an occurrence basis and shall be issued by insurance companies with a general policy
holder’s rating of not less than A- and a financial rating of not less than Class XV as rated in the most current available “Best’s” Insurance Reports. Such insurance companies shall be qualified to do business in the State of
California. All such policies carried by Tenant shall name Landlord, any ground lessor and any lender (or its successors and assigns) as additional insureds, and shall be for the mutual and joint benefit and protection of Landlord, Tenant, any
ground lessor and Landlord’s first mortgagee or beneficiary. All public liability and property damage policies carried by Tenant shall contain a provision that Landlord, although named as an insured, nevertheless shall be entitled to recovery
under said policies for any loss occasioned to it, its servants, agents and employees by reason of the negligence of Tenant. As often as any such policy shall expire or terminate, renewal or additional policies shall be procured and maintained by
Tenant in like manner and to like extent. All policies of insurance must contain a provision that the company writing said policy will give to Landlord thirty (30) days notice in writing in advance of any cancellation or lapse. All public
liability, property damage and other casualty policies carried by Tenant shall be written as primary policies, not contributing with and not in excess of coverage which Landlord may carry. Tenant shall, upon request from Landlord from time to time,
immediately deliver to Landlord copies of all insurance policies (including the declarations pages) in effect with respect to the Premises. All liability policies shall contain endorsements for cross-liability, fire, legal liability, broad form
contractual liability, employer’s automobile non-ownership, products completed operation coverage and dram shop liability, as applicable. 
 12.4 Blanket Policy. 
 Notwithstanding anything to the contrary contained within this Section 12, Tenant’s
obligations to carry the insurance provided for herein may be brought within the coverage of a so-called blanket policy or policies of insurance carried and maintained by Tenant; provided, however, that Landlord, any ground lessor and any
lender shall be named as an additional insured thereunder as their interests appear, the coverage afforded Landlord will not be reduced or diminished by reason of the use of such blanket policy of insurance, and the requirements set forth herein are
otherwise satisfied. 
 12.5 Deductibles. 
 The deductible amounts, if any, with respect to all insurance, which Tenant is required to maintain hereunder, shall not exceed Twenty Thousand Dollars, ($20,000) per claim or occurrence. The amount of the
deductibles, if any, within this limitation shall be a business decision by Tenant; under no circumstances shall Landlord be required to reimburse Tenant for the amount of any deductible incurred by Tenant in connection with any insured event,
except to the extent the event resulting in the claim was caused by Landlord’s or Landlord’s agents’ gross negligence or willful misconduct. 
  

 26 

 12.6 Certificates. 
 Upon the execution and delivery of this Lease and thereafter not less than thirty (30) days prior to the expiration dates of the expiring policies theretofore maintained, Tenant shall deliver to Landlord
certificates of insurance with respect to the policies of insurance required by this Lease or duplicate originals of all such policies. Landlord, upon reasonable notice, may inspect and copy any policies of insurance, and any records relating
thereto kept and maintained by Tenant. 
 12.7 Adjustment in the Event of Loss. 
 Except as otherwise provided herein, all insurance proceeds payable with respect to any damage or destruction to the Premises (but not with respect to
Tenant’s personal property, it being understood that insurance proceeds allocable to Tenant’s personal property shall be payable directly to Tenant) shall be payable to Landlord and Tenant, jointly, to be held in an interest bearing
account. If Tenant and Landlord undertake to repair said damage in accordance with Article 15 below, the proceeds shall be made available to Tenant as to the tenant improvements and to Landlord as to the Building and Common Area used to fund the
reconstruction. In all other events, the proceeds shall be the sole property of Landlord except otherwise expressly provided herein. Landlord shall be entitled to compromise, adjust or settle any and all claims with respect to insurance carried by
it covering the Premises. Each party agrees to execute and deliver to the other party such releases, endorsements and other instruments as the other party reasonably may require in order to compromise, adjust or settle any insurance claim which such
other party shall be entitled to compromise, adjust or settle pursuant to this paragraph and to enable the other party or its designee to collect such insurance proceeds as are payable in respect of such claim. 
 12.8 Proration Upon Termination. 
 If
any of the insurance required to be carried by Tenant hereunder is still in effect at the termination of this Lease, Landlord may elect to terminate such insurance, or Landlord shall reimburse Tenant for the pro rata portion of the premium paid by
Tenant for such insurance based upon the number of days remaining unexpired in such insurance. 
 12.9 Waiver of Subrogation.

 To the extent permitted by law and without affecting the coverage provided by insurance required to be maintained hereunder, Landlord
and Tenant each waive any right to recover against the other with respect to (i) damage to property, (ii) damage to the Premises or any part thereof, or (iii) claims arising by reason of any of the foregoing, but only to the extent
that any of the foregoing damages and claims under clauses (i)-(iii) hereof are covered, and only to the extent of such coverage, by casualty insurance actually carried by either Landlord or Tenant. This provision is intended to waive fully,
and for the benefit of each party, any rights and claims which might give rise to a right of subrogation in any insurance carrier. Each party shall procure a clause or endorsement on any casualty insurance policy denying to the insurer rights of
subrogation against the other party to the extent rights have been waived by the insured prior to the occurrence of injury or loss. Coverage provided by insurance maintained by Tenant shall not be limited, reduced or diminished by virtue of the
subrogation waiver herein contained. 
  

 27 

 12.10 Indemnification. 
 (a) Tenant’s Indemnification Obligations. 
 Tenant shall indemnify, defend, and hold Landlord and its lenders, agents, employees, directors, officers, managers, members, partners, affiliates, independent contractors, and property managers (collectively, “Landlord’s
Agents” or “Agents”) harmless from and against any and all claims, demands, liability, loss or damage, whether for injury to or death of persons or damage to real or personal property, arising out of or in connection with
the Premises, Tenant’s use of the Premises, any activity, work, or other thing done, permitted, or suffered by Tenant in or about the Buildings, or arising from any reason or cause whatsoever in connection with the use or occupancy of the
Premises by any party during the Term of this Lease, except to the extent that the event giving rise to the claim, demand, liability, loss or damage was caused by the gross negligence or willful misconduct of Landlord or Landlord’s Agents.
Tenant shall further indemnify, defend, and hold Landlord and Landlord’s Agents harmless against and from any and all claims arising from any breach or default in the performance of any obligation on Tenant’s part to be performed under the
terms of this Lease, or arising from any act or negligence of Tenant or any officer, agent, employee, guest, or invitee of Tenant, and from and against all costs, attorneys’ fees, expenses, and liabilities incurred as a result of any such claim
or any action or proceeding brought thereon. In any case, action, or proceeding brought against Landlord or Landlord’s Agents by reason of any such claim, Tenant, upon notice from Landlord, shall defend the same at Tenant’s expense by
counsel reasonably satisfactory to Landlord. Tenant, as a material part of the consideration to Landlord, hereby assumes all risk of damage to property or injury to persons in, upon, or about the Premises from any cause arising prior to the later of
the termination of this Lease or the date Tenant has performed all obligations under Section 10.1(d) and is no longer in possession of the Premises (except for such damage or injury caused by Landlord’s or Landlord’s Agents’
willful misconduct or gross negligence), and Tenant hereby waives all claims in respect thereof against Landlord and Landlord’s Agents. Tenant’s obligation to indemnify under this paragraph shall include attorneys’ fees, investigation
costs, and other reasonable costs, expenses, and liabilities incurred by Landlord and Landlord’s Agents. If the ability of Tenant to use the Premises or the Buildings is interrupted for any reason, Landlord and Landlord’s Agents shall not
be liable to Tenant for any loss or damages occasioned by such loss of use, except to the extent such loss or damages is caused by Landlord’s or its Agents’ willful misconduct or gross negligence. 
 (b) Landlord’s Indemnification Obligations. 
 Landlord shall indemnify, defend and hold Tenant and its members, partners, shareholders, officers, directors, agents and employees harmless from any and all liability for injury to or death of any person, or loss of
or damage to the property of any person, and all actions, claims, demands, costs (including, without limitation, reasonable attorneys’ fees), damages or expenses of any kind arising therefrom which may be brought or made against Tenant or which
Tenant may pay or incur, to the extent such liabilities or other matters arise in, on or about the Premises by reason of the gross negligence or willful misconduct or omission by Landlord or Landlord’s Agents. Landlord shall further indemnify,
defend, and hold Tenant and its members, partners, shareholders, officers, directors, agents and employees harmless against and from any and all claims arising from any breach or default in the performance of any 

  

 28 

 
obligation on Landlord’s part to be performed under the terms of this Lease, and from and against all costs, attorneys’ fees, expenses, and
liabilities incurred as a result of any such claim or any action or proceeding brought thereon. In any case, action, or proceeding brought against Tenant or its members, partners, shareholders, officers, directors, agents and employees by reason of
any such claim, Landlord, upon notice from Tenant, shall defend the same at Landlord’s expense by counsel reasonably satisfactory to Tenant. 
 12.11 Limitation on Landlord Liability. 
 Neither Landlord nor Landlord’s Agents shall be liable for loss or damage to
any property by theft or otherwise, or for any injury to or damage to persons or property resulting from fire, explosion, falling plaster, steam, gas, electricity, water, or rain which may leak from any part of the Buildings or from the pipes,
appliances, or plumbing works therein or from the roof, street, or subsurface or from any other place resulting from dampness or any other cause whatsoever, except to the extent caused by the gross negligence or willful misconduct of Landlord or
Landlord’s Agents. Neither Landlord nor Landlord’s Agents, shall be liable for interference with or loss of business by Tenant. Tenant shall give prompt written notice to Landlord in case of fire or accidents in the Premises or in the
Buildings or of defects therein or in the fixtures or equipment belonging to Landlord. If Landlord is in default of this Lease, and as a consequence, Tenant recovers a money judgment against Landlord, the judgment shall be satisfied only out of the
proceeds of sale received on execution of the judgment and levy against the right, title, and interest of Landlord in the Premises, and out of rent or other income from the Premises receivable by Landlord or out of the consideration received by
Landlord from the sale or other disposition of all or any part of Landlord’s right, title, and interest in the Premises. Landlord’s Agents shall not be personally liable for any deficiency except to the extent liability is based upon
willful misconduct. If Landlord is a partnership, joint venture, or limited liability company, the partners or members of such partnership or limited liability company, as the case may be, shall not be personally liable and no partner or member of
Landlord (or of any affiliated entity) shall be sued or named as a party in any suit or action, or service of process be made against any partner or member of Landlord (or of any affiliated entity), except as may be necessary to secure jurisdiction
of the partnership, joint venture, or limited liability company or to the extent liability is caused by willful misconduct. If Landlord is a corporation, the shareholders, directors, officers, employees, and/or agents of such corporation shall not
be personally liable and no shareholder, director, officer, employee, or agent of Landlord shall be sued or named as a party in any suit or action, or service of process be made against any shareholder, director, officer, employee or agent of
Landlord, except as may be necessary to secure jurisdiction of the corporation. No partner, member, shareholder, director, employee, or agent of Landlord (or of any affiliated entity) shall be required to answer or otherwise plead to any service of
process and no judgment will be taken or writ of execution levied against any partner, shareholder, director, employee, or agent of Landlord. 
  

 29 

 13. SUBLEASE AND ASSIGNMENT. 
 13.1 Assignment and Sublease of Building. 
 (a) Consent Required. 
 Except in connection with a Permitted Transfer, Tenant shall neither voluntarily nor by operation of law assign, sell, encumber, pledge or otherwise
transfer all or any part of Tenant’s leasehold estate hereunder, or permit any other person (excepting Tenant’s agents and employees) to occupy the Premises or any portion thereof, without Landlord’s prior written consent, which
consent shall be not be unreasonably withheld, delayed or conditioned Consent by Landlord to one or more assignments of this Lease or to one or more sublettings of the Premises shall not constitute a waiver of Landlord’s right to require
consent to any subsequent assignment, subletting or other transfer. If Tenant is a corporation, unincorporated association or partnership, the transfer, assignment or hypothecation of any stock or interest in such corporation, association or
partnership in the aggregate in excess of twenty-five percent (25%) of all outstanding stock or interests, or liquidation thereof, shall be deemed an assignment within the meaning and provisions of this section and the sale of all or
substantially all of the assets of Tenant shall be deemed an assignment within the meanings and provisions of this section. The foregoing sentence shall not apply to: (i) any corporation or partnership which is a reporting company under the
Securities Exchange Act of 1934, or (ii) a sale to an entity with a net worth, as designated in its most recent financial statement (no older than 3 months), equal to or greater than Tenant’s net worth on the Effective Date. Tenant shall
reimburse Landlord for all of Landlord’s reasonable costs and attorneys’ fees incurred in conjunction with the processing and documentation of any required consent to assignment, subletting, transfer, change of ownership or hypothecation
of this Lease or Tenant’s interest in and to the Premises, not to exceed One Thousand Dollars ($1,000) per request plus reasonable out-of-pocket expenses payable to third parties. Any purported sublease or assignment of Tenant’s interest
in this Lease requiring but not having received Landlord’s consent thereto (to the extent such consent is required hereunder) shall be void. 
 (b) Permitted Transfers. 
 Notwithstanding the foregoing, (i) any bona fide financing or capitalization, including a
public offering of the common stock of Tenant, shall not be deemed to be an assignment hereunder; and (ii) Tenant shall have the right to assign this Lease or sublet the Buildings, or any portion thereof, without Landlord’s consent, to any
Affiliate of Tenant, or to any entity which results from a merger, reorganization or consolidation with Tenant, or to any entity which acquires substantially all of the stock or assets of Tenant as a going concern (hereinafter each a
“Permitted Transfer”). For purposes of the preceding sentence, an “Affiliate” of Tenant shall mean any entity in which Tenant owns at least a twenty five percent (25%) equity interest, any entity which owns at
least a twenty five percent (25%) equity interest in Tenant and/or any entity which is related to Tenant by a chain of ownership interests involving at least twenty five percent (25%) equity interest at each level in the chain. Landlord
shall have no right to terminate this Lease in connection with, and shall have no right to any sums or other economic consideration resulting from, any Permitted Transfer. The transferee under such Permitted Transfer shall be and remain subject to
all of the terms and provisions of this Lease. 
 (c) Consent Required. 
 Landlord’s consent may be based upon a determination that the same type, class, nature and quality of business, services, management and financial
soundness of ownership shall exist after the proposed assignment or subletting and, provided further, that each and every covenant, 

  

 30 

 
condition and obligation imposed upon Tenant by this Lease and each and every right, remedy and benefit afforded Landlord by this Lease and the underlying
purpose of this Lease is not thereby impaired or diminished. The determination by Landlord as to whether consent will be granted in any specific instance may be based on, without limitation, the following factors, which shall be in Landlord’s
reasonable discretion: (a) whether the transferee’s use of the Premises will be compatible with the provisions of this Lease; (b) the financial capacity of the transferee; (c) the business reputation of the transferee;
(d) the quality and type of the business operations of the transferee; and (e) the business experience of the proposed transferee. This list of factors is not intended to be exclusive, and Landlord may rely on such other basis for judgment
as may apply from time to time. 
 (d) Procedure to Obtain Consent. 
 If Tenant desires at any time to assign this Lease or to sublet the Premises or any portions thereof, it first shall notify Landlord of its desire to do
so and shall submit in writing to Landlord (i) the name and legal composition of the proposed subtenant or assignee; (ii) the nature of the proposed subtenant’s or assignee’s business to be carried on in the Premises; (iii) the
terms and provisions of the proposed sublease or assignment and all transfer documents relating to the proposed transfer; and (iv) such reasonable business and financial information as Landlord may request concerning the proposed subtenant or
assignee. Any request for Landlord’s approval of a sublease or assignment shall be accompanied with a check in such reasonable amount as Landlord shall advise for the cost of review and preparation, including reasonable attorneys’ fees, of
any documents relating to such proposed transfer, not to exceed One Thousand Dollars ($1,000) for each transfer plus reasonable out-of-pocket expenses payable to third parties. The provisions and conditions of any proposed sublease or assignment
must not be inconsistent with any provision of this Lease, and must address all matters contained in this Lease. In addition, the transferee must expressly assume all of the obligations of Tenant under this Lease. Notwithstanding the assumption of
the obligations of this Lease by the transferee, no subletting or assignment, even with the consent of Landlord, shall relieve Tenant of its continuing obligation to pay the rent and perform all the other obligations to be performed by Tenant
hereunder. The obligations and liability of Tenant hereunder shall continue notwithstanding the fact that Landlord may accept rent and other performance from the transferee. The acceptance of rent by Landlord from any other person shall not be
deemed to be a waiver by Landlord of any provision of this Lease or to be a consent to any assignment or subletting. 
 (e) Sublease of
Phase 2A. 
 In the event of any sublease of Phase 2A, in addition to any other payment obligation of Tenant hereunder, Tenant shall remit
to Landlord, as additional rent, as and when received by Tenant, all net subrents received from a subtenant in excess of $2.00 per rentable square foot per month. For purposes of this section “net subrents” are defined as all rents
received from a subtenant however designated, net of any out-of-pocket costs incurred by Tenant to sublease the space and net of any payments received from a subtenant as reimbursement of operating expenses, taxes, utilities or service fees.

  

 31 

 13.2 Rights of Landlord: Effect of Landlord’s Consent. 
 Consent by Landlord to one or more assignments of this Lease, or to one or more sublettings of the Buildings or any portion thereof, or collection of rent
by Landlord from any assignee or sublessee, shall not operate to exhaust Landlord’s rights under this Article 13, nor constitute consent to any subsequent assignment or subletting. No assignment of Tenant’s interest in this Lease and no
sublease shall relieve Tenant of its obligations hereunder, notwithstanding any waiver or extension of time granted by Landlord to any assignee or sublessee, or the failure of Landlord to assert its rights against any assignee or sublessee, and
regardless of whether Landlord’s consent thereto is given or required to be given hereunder. In the event of a default by any assignee, sublessee or other successor of Tenant in the performance of any of the terms or obligations of Tenant under
this Lease, Landlord may proceed directly against Tenant without the necessity of exhausting remedies against any such assignee, sublessee or other successor. 
 13.3 Advertising. 
 In no event shall Tenant display on or about the Premises any signs for the
purpose of advertising the Premises for assignment, subletting or other transfer of rights, without the Landlord’s prior consent, which shall not be unreasonably withheld or delayed. Landlord shall not display on or about the Premises any signs
for the purpose of advertising any of the Real Property for lease, subletting, assignment or rent except with the consent of Tenant, which consent shall not be unreasonably withheld or delayed. 
 13.4 Writing Required. 
 Each
Permitted Transfer, permitted assignment or sublease shall be consummated by an instrument in writing executed by the transferor and transferee in form satisfactory to Landlord. Each assignee and subtenant shall agree in writing for the benefit of
the Landlord herein to assume all obligations of Tenant hereunder which are applicable to the space subject to the assignment or sublease and any associated common areas, including the payment of all amounts due or to become due under this Lease
directly to the Landlord. At least one executed copy of such written instrument shall be delivered to the Landlord. 
 13.5 Transfer
Premiums. 
 If Tenant assigns or sublets its rights under this Lease, Tenant shall pay to Landlord as additional rent, after Tenant has
recovered any relevant leasing commissions, costs of tenant improvements and other expenses of the assignment or sublease, the unamortized (over the Term of the Lease) costs of any tenant improvements consented to by Landlord paid for by Tenant
prior to such Transfer, one-half (1/2) of all such excess consideration due and payable to Tenant from said assignment or sublease to the extent said consideration exceeds the rent or a pro rata portion of the rent, in the event only a portion
of the Premises is sublet or assigned. 
 14. RIGHT OF ENTRY AND QUIET ENJOYMENT. 
 14.1 Right of Entry. 
 Landlord and
its authorized representatives shall have the right to enter the Buildings at any time during the Term of this Lease during normal business hours when accompanied by a 

  

 32 

 
representative of Tenant and upon not less than twenty-four (24) hours prior notice, except in the case of emergency (in which event no notice and no
accompaniment shall be required and entry may be made at any time), for the purpose of inspecting and determining the condition of the Buildings or for any other proper purpose including, without limitation, to make repairs, replacements or
improvements which Landlord may be entitled to make hereunder, to show the Buildings to prospective purchasers, lenders and investors, to show the Buildings to prospective tenants (but only during the final eighteen (18) months of the Term of
this Lease), and to post notices of nonresponsibility. Landlord shall not be liable for inconvenience, annoyance, disturbance, loss of business, quiet enjoyment or other damage or loss to Tenant by reason of making any repairs or performing any work
upon the Premises or by reason of erecting or maintaining any protective barricades in connection with any such work, and the obligations of Tenant under this Lease shall not thereby be affected in any manner whatsoever, provided, however,
Landlord shall use its best reasonable efforts to minimize the inconvenience to Tenant’s normal business operations caused thereby. 
 14.2 Quiet Enjoyment. 
 Landlord covenants that Tenant, upon paying the rent and performing its obligations hereunder and
subject to all the terms and conditions of this Lease, shall peacefully and quietly have, hold and enjoy the Premises throughout the Term of this Lease, or until this Lease is terminated as provided by this Lease. 
 15. CASUALTY AND TAKING. 
 15.1 Damage or
Destruction. 
 (a) Termination Rights. 
 If the Buildings, or the Common Areas necessary for Tenant’s use and occupancy of the Premises, are damaged or destroyed in whole or in part under circumstances in which (i) repair and restoration is
permitted under applicable governmental laws, regulations and building codes then in effect and (ii) repair and restoration reasonably can be completed within a period of one (1) year (or, in the case of an occurrence during the last year
of the Term of this Lease, within a period of sixty (60) days) following the date of the occurrence, then Landlord, as to the Buildings and Common Areas and the tenant improvements, shall commence and complete, with all due diligence and as
promptly as is reasonably practicable under the conditions then existing, all such repair and restoration as may be required to return the affected portions of the Real Property to a condition comparable to that existing immediately prior to the
occurrence. In the event of damage or destruction the repair of which is not permitted under applicable governmental laws, regulations and building codes then in effect, or if such damage or destruction (despite being repaired to the extent then
permitted under applicable governmental laws, regulations and building codes) would materially impair Tenant’s ability to conduct its business in the Premises, then either party may terminate this Lease as of the date of the occurrence by
giving written notice to the other within sixty (60) days after the date of the occurrence; if neither party timely elects such termination, or if such damage or destruction after being repaired would not materially impair Tenant’s ability
to conduct its business in the Premises, then this Lease shall continue in full force and effect, except that there shall be an equitable adjustment in monthly 

  

 33 

 
Minimum Rental and of Tenant’s Operating Cost Share, based upon the extent to which Tenant’s ability to conduct its business in the Premises is
impaired, and Landlord shall restore the Common Areas and Building and tenant improvements to a complete architectural whole and to a functional condition. In the event of damage or destruction which cannot reasonably be repaired within one
(1) year (or, in the case of an occurrence during the last twenty-four (24) months of the Term of this Lease, within a period of sixty (60) days) following the date of the occurrence, then either Landlord or Tenant, at its election,
may terminate this Lease as of the date of the occurrence by giving written notice to the other within thirty (30) days after the date of the occurrence; if neither party timely elects such termination, then this Lease shall continue in full
force and effect and Landlord shall repair and restore applicable portions of the Real Property in accordance with the first sentence of this Section 15. Landlord and Tenant agree that the terms of this Lease shall govern the effect of any
damage to or destruction of the Project with respect to termination of this Lease and hereby waive the provisions of any present or future statute to the extent inconsistent herewith. 
 (b) Limitations on Parties’ Obligations. 
 The obligations of Landlord pursuant to Section 15.1(a) are subject to the following limitations: 
 (i) If the occurrence
results from a peril which is required to be insured pursuant to Section 12.1(c) above, the obligations of Landlord shall not exceed the amount of insurance proceeds received from insurers (or, in the case of any failure to maintain required
insurance, proceeds that reasonably would have been available if the required insurance had been maintained) by reason of such occurrence, plus the amount of the permitted deductible (provided that Landlord shall be obligated to use its best efforts
to recover any available proceeds from the insurance which it is required to maintain pursuant to the provisions of Article 12, and, if such proceeds (including, in the case of a failure to maintain required insurance, any proceeds that reasonably
would have been available) are insufficient, either party may terminate the Lease unless the other party promptly elects and agrees, in writing, to contribute the amount of the shortfall; and 
 (ii) If the occurrence results from a peril which is not required to be insured pursuant to Article 12 above and is not actually insured, Landlord shall
be required to repair and restore the Building and Common Areas and tenant improvements to the extent necessary for Tenant’s continued use and occupancy of the Buildings, provided that Landlord’s obligation to repair and restore shall not
exceed an amount equal to ten percent (10%) of the replacement cost of the Building and Common Area improvements and ten percent (10%) of the replacement cost of the tenant improvements; if the cost to repair and restore exceeds such
amount, then Landlord may terminate this Lease unless the Tenant promptly elects and agrees, in writing, to contribute the amount of the shortfall. 
 (c) Entitlement to Insurance Proceeds. 
 If this Lease is terminated pursuant to the foregoing provisions of this
Section 15.1 following an occurrence which is a peril actually insured or required to be insured against pursuant to Article 12, Landlord and Tenant agree (and any Lender shall be asked to agree) that 

  

 34 

 
such insurance proceeds, after repayment of the loan, shall be allocated between Landlord and Tenant in a manner which fairly and reasonably reflects their
respective ownership rights under this Lease, as of the termination or expiration of the Term of this Lease, with respect to the improvements, fixtures, equipment and other items to which such insurance proceeds are attributable. 
 (d) Abatement of Rent. 
 From and
after the date of an occurrence resulting in damage to or destruction of the Buildings or of the Common Areas necessary for Tenants use and occupancy of the Buildings, and continuing until the earlier of the date repair and restoration thereof are
completed or the date on which rental loss insurance payments cease, there shall be an equitable abatement of Minimum Rental and of Tenant’s Operating Cost Share of Operating Expenses based upon the degree to which Tenant’s ability to
conduct its business in the Buildings is impaired. 
 15.2 Condemnation. 
 (a) Termination Rights. 
 If during the
Term of this Lease the Real Property or Improvements or any substantial part of either, is taken by eminent domain or by reason of any public improvement or condemnation proceeding, or in any manner by exercise of the right of eminent domain
(including any transfer in avoidance of an exercise of the power of eminent domain), then (i) this Lease shall terminate as to the entire affected Premises at Landlord’s election by written notice given to Tenant within sixty
(60) days after the taking has occurred, and (ii) this Lease shall terminate as to the entire affected Premises at Tenant’s election, by written notice given to Landlord within thirty (30) days after the nature and extent of the
taking have been finally determined, if the portion of the Premises taken is of such extent and nature as substantially to handicap, impede or permanently impair Tenant’s use of the balance of the Premises, and (iii) this Lease shall
remain in full force and effect as to the remaining portion of the Premises. If Tenant elects to terminate this Lease, as to the affected Premises, Tenant shall also notify Landlord of the date of termination, which date shall not be earlier than
thirty (30) days nor later than ninety (90) days after Tenant has notified Landlord of Tenant’s election to terminate, except that this Lease shall terminate on the date of taking if such date falls on any date before the date of
termination designated by Tenant. If neither party elects to terminate this Lease as hereinabove provided, this Lease shall continue in full force and effect (except that there shall be an equitable abatement of Minimum Rental and of Tenant’s
Operating Cost Share of Operating Expenses based upon the degree to which Tenant’s ability to conduct its business in the Premises is impaired), Landlord shall restore the Building and Common Area and tenant improvements to a complete
architectural whole and a functional condition and as nearly as reasonably possible to the condition existing before the taking. In connection with any such restoration, Landlord shall use its best efforts (including, without limitation, any
necessary negotiation or intercession with its lender, if any) to ensure that any severance damages or other condemnation awards intended to provide compensation for rebuilding or restoration costs are promptly collected and made available to Tenant
and Landlord subject only, to such payment controls as either party or its lender may reasonably require in order to ensure the proper application of such proceeds toward the restoration of the Improvements. Each party waives the provisions of Code
of Civil Procedure Section 1265.130, allowing either party to petition the Superior Court to terminate this Lease in the event of a partial condemnation of the Buildings or Real Property. 
  

 35 

 (b) Limitations on Parties’ Obligations. 
 The obligations of Landlord pursuant to Section 15.2(a) are subject to the following limitations: 
 (i) Landlord’s obligation to repair and restore shall not exceed, net of any condemnation awards or other proceeds available for and allocable to
such restoration as contemplated in Section 15.2(a), an amount equal to ten percent (10%) of the replacement cost of the Building and Common Area improvements and an amount equal to ten percent (10%) of the replacement cost of the
tenant improvements; if the replacement cost exceeds such amount, then Landlord may terminate this Lease unless Tenant promptly elects and agrees, in writing, to contribute the amount of the shortfall; and 
 (ii) If this Lease is terminated pursuant to the foregoing provisions of this Section 15.2, or if this Lease remains in effect but any condemnation
awards or other proceeds become available as compensation for the loss or destruction of any of the Improvements, then Landlord and Tenant agree (and any Real Property lender shall be asked to agree) that such proceeds shall be allocated between
Landlord and Tenant, respectively, in the respective proportions in which Landlord and Tenant would have shared, under Section 15.1(c), the proceeds of any insurance proceeds following loss or destruction of the applicable Improvements by an
insured casualty. 
 15.3 Reservation of Compensation. 
 Landlord reserves, and Tenant waives and assigns to Landlord, all rights to any award or compensation for damage to the Improvements and the Real Property, but not the leasehold estate created hereby, accruing by
reason of any taking in any public improvement, condemnation or eminent domain proceeding or in any other manner by exercise of the right of eminent domain or of anything lawfully done by public authority, except that (a) Tenant shall be
entitled to any and all compensation or damages expressly awarded to Tenant on account of Tenant’s loss of the leasehold estate and Tenant’s moving expenses, trade fixtures and equipment and any leasehold improvements installed by Tenant
in the Buildings at its own sole expense, but only to the extent Tenant would have been entitled to remove such items at the expiration of the Term of this Lease and then only to the extent of the then remaining unamortized value of such
improvements computed on a straight-line basis over the Term of this Lease, and (b) any condemnation awards or proceeds described in Section 15.2(b)(ii) shall be allocated and disbursed in accordance with the provisions of Section 15.2(b)(ii),
notwithstanding any contrary provisions of this Section 15.3. 
 15.4 Restoration of Improvements. 
 In connection with any repair or restoration of Improvements following a casualty or taking as hereinabove set forth, the party responsible for such
repair or restoration shall, to the extent possible, return such Improvements to a condition substantially equal to that which existed immediately prior to the casualty or taking. To the extent such party wishes to make material 

  

 36 

 
modifications to such Improvements, such modifications shall be subject to the prior written approval of the other party (not to be unreasonably withheld,
delayed or conditioned), except that no such approval shall be required for modifications that are required by applicable governmental authorities as a condition of the repair or restoration, unless such required modifications would substantially
impair or impede Tenant’s conduct of its business in the Buildings (in which case any such modifications in the Building shall require Tenant’s consent, not unreasonably withheld, delayed or conditioned) or would materially affect the
exterior appearance, the structural integrity or the mechanical or other operating systems of the Buildings (in which case any such modifications shall require Tenant’s consent, not to be unreasonably withheld, delayed or conditioned).

 16. DEFAULT. 
 16.1 Events of
Default. 
 The occurrence of any of the following shall constitute an event of default on the part of Tenant: 
 (a) Nonpayment. 
 Failure to pay, when
due, any amount payable to Landlord hereunder, such failure continuing for a period of five (5) business days after written notice of such failure; 
 (b) Other Obligations. 
 Failure to perform any obligation, agreement or covenant under this Lease
other than those matters specified in subsection (a) hereof, such failure continuing for thirty (30) days after written notice of such failure; provided, however, that if such failure is curable in nature but cannot reasonably be
cured within such 30-day period, then Tenant shall not be in default if, and so long as, Tenant promptly (and in all events within such 30-day period) commences such cure and thereafter diligently pursues such cure to completion; and provided
further, however, that any such notice shall be in lieu of, and not in addition to, any notice required under California Code of Civil Procedure Section 1161 et seq., as amended from time to time. Notwithstanding the foregoing, if any such
failure on the part of Tenant affects or threatens to affect the health or safety of others, or would result in the destruction of property, Tenant shall immediately begin to cure and shall use its diligent and best efforts in pursuing said cure to
completion (it being understood and agreed that Landlord shall not be entitled to exercise any remedy to terminate this Lease unless and until such failure shall have continued for thirty (30) days after written notice of such failure);

 (c) General Assignment. 
 A general assignment by Tenant for the benefit of creditors; 
 (d) Bankruptcy. 
 The filing of any voluntary petition in bankruptcy by Tenant, or the filing of an involuntary petition by Tenant’s creditors, which involuntary
petition remains undischarged for a 

  

 37 

 
period of sixty (60) days. In the event that under applicable law the trustee in bankruptcy or Tenant has the right to affirm this Lease and continue to
perform the obligations of Tenant hereunder, such trustee or Tenant shall, in such time period as may be permitted by the bankruptcy court having jurisdiction, cure all defaults of Tenant hereunder outstanding as of the date of the affirmance of
this Lease and provide to Landlord such adequate assurances as may be necessary to ensure Landlord of the continued performance of Tenant’s obligations under this Lease. Specifically, but without limiting the generality of the foregoing, such
adequate assurances must include assurances that the Buildings continue to be operated only for the use permitted hereunder. The provisions hereof are to assure that the basic understandings between Landlord and Tenant with respect to Tenant’s
use of the Premises and the benefits to Landlord therefrom are preserved, consistent with the purpose and intent of applicable bankruptcy laws; 
 (e) Receivership. 
 The employment of a receiver appointed by court order to take possession of substantially all of Tenants
assets or its interest in the Buildings, if such receivership remains undissolved for a period of sixty (60) days; 
 (f)
Attachment. 
 The attachment, execution or other judicial seizure of all or substantially all of Tenant’s assets or its interest
in the Buildings, if such attachment or other seizure remains undismissed or undischarged for a period of sixty (60) days after the levy thereof; or 
 (g) Insolvency. 
 The admission by Tenant in writing of its inability to pay its debts as they become
due, the filing by Tenant of a petition seeking any reorganization or arrangement, composition, readjustment, liquidation, dissolution or similar relief under any present or future statute, law or regulation, the filing by Tenant of an answer
admitting or failing timely to contest a material allegation of a petition filed against Tenant in any such proceeding or, if within sixty (60) days after the commencement of any proceeding against Tenant seeking any reorganization or
arrangement, composition, readjustment, liquidation, dissolution or similar relief under any present or future statute, law or regulation, such proceeding shall not have been dismissed. 
 16.2 Remedies Upon Tenant’s Default. 
 (a) Re-entry; Termination. 
 Upon the occurrence of any event of default described in Section 16.1 hereof, Landlord, in
addition to and without prejudice to any other rights or remedies it may have, shall have the immediate right to re-enter the Buildings or any part thereof and repossess the same, expelling and removing therefrom all persons and property (which
property may be stored in a public warehouse or elsewhere at the cost and risk of and for the account of Tenant). In addition to or in lieu of such re-entry, and without prejudice to any other rights or remedies it may have, Landlord shall have the
right either (i) to terminate this Lease and recover from Tenant all damages incurred by Landlord as a result of Tenant’s default, as hereinafter provided, or (ii) to continue this Lease in effect and recover rent and other charges
and amounts as they become due. 
  

 38 

 (b) Continuation of Lease. 
 Even if Tenant has breached this Lease and abandoned the Buildings, this Lease shall continue in effect for so long as Landlord does not terminate
Tenant’s right to possession and Landlord may enforce all of its rights and remedies under this Lease, including the right to recover rent as it becomes due, and Landlord, without terminating this Lease, may exercise all of the rights and
remedies of a lessor under 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 right to sublet or assign, subject only to
reasonable limitations), or any successor Code section. Acts of maintenance, preservation or efforts to relet the Buildings or the appointment of a receiver upon application of Landlord to protect Landlord’s interests under this Lease shall not
constitute a termination of Tenant’s right to possession. 
 (c) Remedies. 
 If Landlord terminates this Lease pursuant to this Section 16.2, Landlord shall have all of the rights and remedies of a landlord provided by
Section 1951.2 of the Civil Code of the State of California, or any successor Code section, which remedies include Landlord’s right to recover from Tenant (i) the worth at the time of award of the unpaid rent and additional rent and
Tenant’s Operating Cost Share of Operating Expense which had been earned at the time of termination, (ii) the worth at the time of award of the amount by which the unpaid rent and additional rent and Tenant’s Operating Cost Share of
Operating Expense 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, (iii) the worth at the time of award of the amount by which
the unpaid rent and additional rent and Tenant’s Operating Cost Share of Operating Expense for the balance of the Term, after the time of award exceeds the amount of such rental loss that Tenant proves could be reasonably avoided, and
(iv) any other amount reasonably 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, including, but not limited to, the cost of recovering possession of the Buildings, expenses of reletting, including necessary repair, renovation and alteration of the Buildings, reasonable attorneys’ fees, and other reasonable costs.
The “worth at the time of award” of the amounts referred to in clauses (i) and (ii) above shall be computed by allowing interest at twelve percent (12%) per annum from the date such amounts accrued to Landlord. The
“worth at the time of award” of the amounts referred to in clause (iii) above shall be computed by discounting such amount at one percentage point above the discount rate of the Federal Reserve Bank of San Francisco at the time of
award. 
 16.3 Remedies Cumulative. 
 All rights, privileges and elections or remedies of Landlord contained in this Article 16 are cumulative and not alternative to the extent permitted by law and except as otherwise provided herein. 
  

 39 

 16.4 Landlord’s Default. 
 Landlord shall not be deemed to be in default of this Lease unless Landlord fails within a reasonable time (or the time specified herein, if applicable)
to perform an obligation required to be performed by it. Tenant agrees to give Landlord and any lender designated by Landlord notice of any Landlord default, and a reasonable opportunity to cure such default. 
 17. SUBORDINATION, ATTORNMENT AND SALE. 
 17.1
Subordination to Mortgage. 
 This Lease, and any sublease entered into by Tenant under the provisions of this Lease, shall be subject and
subordinate to any ground lease, mortgage, deed of trust, sale/leaseback transaction or any other hypothecation for security now or hereafter placed upon the Buildings, the Real Property, or any of them, and the rights of any assignee of Landlord or
of any ground lessor, mortgagee, trustee, beneficiary or leaseback lessor under any of the foregoing, and to any and all advances made on the security thereof and to ail renewals, modifications, consolidations, replacements and extensions thereof;
provided, however, that such subordination in the case of any future ground lease, mortgage, deed of trust, sale/leaseback transaction or any other hypothecation for security placed upon the Buildings, the Real Property, or any of them shall
be conditioned on Tenant’s receipt from the ground lessor, mortgagee, trustee, beneficiary or leaseback lessor of a Non-Disturbance Agreement in a form reasonably acceptable to Tenant (i) confirming that so long as Tenant is not in
material default hereunder beyond any applicable cure period (for which purpose the occurrence of any event of default under Section 16.1 hereof shall be deemed to be “material”), Tenant’s rights hereunder shall not be disturbed
by such person or entity and (ii) agreeing that the benefit of such Non-Disturbance Agreement shall be transferable to any transferee under a Permitted Transfer and to any other assignee or subtenant that is acceptable to the ground lessor,
mortgagee, trustee, beneficiary or leaseback lessor at the time of transfer. Tenant agrees to execute such other commercially reasonable documentation as may be required by an institutional lender to evidence such subordination and to attorn to any
such ground lessor, mortgagee, trustee, beneficiary or leaseback lessor in the event such party succeeds to Landlord’s interest hereunder and agrees to recognize this Lease. Moreover, Tenant’s obligations under this Lease shall be
conditioned on Tenant’s receipt within thirty (30) days after mutual execution of this Lease, from any existing ground lessor, mortgagee, trustee, beneficiary or leaseback lessor currently owning or holding a security interest in the Real
Property, of a Non-Disturbance Agreement in a form reasonably acceptable to Tenant confirming (i) that so long as Tenant is not in material default hereunder beyond any applicable cure period, Tenant’s rights hereunder shall not be
disturbed by such person or entity and (ii) agreeing that the benefit of such Non-Disturbance Agreement shall be transferable to any transferee under a Permitted Transfer and to any other assignee or subtenant that is acceptable to the ground
lessor, mortgagee, trustee, beneficiary or leaseback lessor at the time of transfer. If any mortgagee, trustee, beneficiary, ground lessor, sale/leaseback lessor or assignee elects in writing to have this Lease be an encumbrance upon the Real
Property prior to the lien of its mortgage, deed of trust, ground lease or leaseback lease or other security arrangement and gives notice thereof to Tenant, this Lease shall be deemed prior thereto, whether this Lease is dated prior or subsequent to
the date thereof or the date of recording thereof. Tenant, and any sublessee, shall execute such documents as may reasonably be requested by any mortgagee, 

  

 40 

 
trustee, beneficiary, ground lessor, sale/leaseback lessor or assignee to evidence the subordination herein set forth, subject to the conditions set forth
above, or to make this Lease prior to the lien of any mortgage, deed of trust, ground lease, leaseback lease or other security arrangement, as the case may be. Upon any default by Landlord in the performance of its obligations under any mortgage,
deed of trust, ground lease, leaseback lease or assignment, Tenant (and any sublessee) shall, notwithstanding any subordination hereunder, attorn to the mortgagee, trustee, beneficiary, ground lessor, leaseback lessor or assignee thereunder upon
demand and become the tenant of the successor in interest to Landlord, at the option of such successor in interest, and shall execute and deliver any instrument or instruments confirming the attornment herein provided for. 
 17.2 Sale of Landlord’s Interest. 
 Upon sale, transfer or assignment of Landlord’s entire interest in the Buildings and the Real Property, Landlord shall be relieved of its obligations hereunder with respect to liabilities accruing from and after the date of such sale,
transfer or assignment. 
 17.3 Estoppel Certificates. 
 Tenant or Landlord (the “Responding Party”) as applicable, shall at any time and from time to time, within ten (10) days after written request by the other party (the “Requesting
Party”), execute, acknowledge and deliver to the Requesting Party a certificate in writing stating: (i) that this Lease is unmodified and in full force and effect, or if there have been any modifications, that this Lease is in full
force and effect as modified and stating the date and the nature of each modification; (ii) the date to which rental and all other sums payable hereunder have been paid; (iii) that the Requesting Party is not in default in the performance
of any of its obligations under this Lease, that the certifying party has given no notice of default to the Requesting Party and that no event has occurred which, but for the expiration of the applicable time period, would constitute an event of
default hereunder, or if the responding party alleges that any such default, notice or event has occurred, specifying the same in reasonable detail; and (iv) such other matters as may reasonably be requested by the Requesting Party or by any
institutional lender, mortgagee, trustee, beneficiary, ground lessor, sale/leaseback lessor or prospective purchaser of the Real Property, or prospective sublessee or assignee of this Lease. Any such certificate provided under this Section 17.3
may be relied upon by any lender, mortgagee, trustee, beneficiary, assignee or successor in interest to the Requesting Party, by any prospective purchaser, by any purchaser on foreclosure or sale, by any grantee under a deed in lieu of foreclosure
of any mortgage or deed of trust on the Real Property, by any subtenant or assignee, or by any other third party. Failure to execute and return within the required time any estoppel certificate requested hereunder, if such failure continues for five
(5) days after a second written request by the Requesting Party for such estoppel certificate, shall be deemed to be an admission of the truth of the matters set forth in the form of certificate submitted to the Responding Party for execution.

  

 41 

 18. SECURITY. 
 18.1 Deposit. 
 Upon execution of the original Lease, Tenant deposited with Landlord the sum of $5,500,000. In lieu of a cash
security deposit, Tenant elected to provide one or more irrevocable letters of credit, payable to Landlord, as a security deposit. Upon the execution of this Lease, the amount of such deposit shall be reduced to $1,375,000. At Tenant’s
election, in lieu of a cash security deposit, Tenant may continue to provide one or more irrevocable letters of credit in amounts described above, payable to Landlord, and issued by an institution and in form reasonably satisfactory to Landlord.
Such sums or the Letter of Credit (individually and collectively, the “Security Deposit”) shall be held by Landlord as security for the faithful performance of all of the terms, covenants, and conditions of this Lease to be kept and
performed by Tenant during the Term hereof; provided that if at any time Tenant shall have maintained an investment grade credit rating of BBB or better by Standard and Poors for a consecutive twelve month period, Landlord shall return the Security
Deposit to Tenant. Upon the execution of this Lease, Landlord shall promptly obtain the release of any Letters of Credit pledged as permitted in Section 18.2 below which exceed the amounts indicated above and shall return such Letters of Credit
to Tenant. Upon such release and return, Tenant shall cause to be issued and delivered a substitute letter of credit in the amount of the required security deposit. If Tenant defaults with respect to any provision of this Lease, including, without
limitation, the provisions relating to the payment of rental and other sums due hereunder, Landlord shall have the right, but shall not be required, to use, apply or retain all or any part of the Security Deposit for the payment of rental,
unreimbursed Operating Expenses or any other amount which Landlord may spend or become obligated to spend by reason of Tenant’s default or to compensate Landlord for any other loss or damage which Landlord may suffer by reason of Tenant’s
default. Landlord may also apply the Security Deposit toward costs incurred to repair damages to the Premises or to clean and bring the Premises to good order, condition and repair during its Lease Term and upon expiration or sooner termination of
this Lease. If any portion of the Security Deposit is so used or applied, Tenant shall, within five (5) days after written demand therefor, deposit cash with Landlord in an amount sufficient to restore the Security Deposit to its original
amount and Tenant’s failure to do so shall be a material breach of this Lease. Landlord shall be required to keep any deposit under this Section separate from Landlord’s general funds in an interest bearing account reasonably acceptable to
Tenant, and Tenant shall be entitled to the interest thereon, to be paid to Tenant when and if the Security Deposit is refundable to Tenant. If Tenant fully and faithfully performs every provision of this Lease to be performed by it, the Security
Deposit, or any balance thereof, together with all accrued interest, shall be returned to Tenant or, at Landlord’s option, to the last assignee of Tenant’s interest hereunder, at the expiration of the Term of this Lease and after Tenant
has vacated the Premises. In the event of termination of Landlord’s interest in this Lease, Landlord shall transfer all deposits then held by Landlord under this Section to Landlord’s successor in interest, whereupon Tenant agrees to
release Landlord from all liability for the return of such deposit or the accounting thereof. 
 18.2 Pledge of Security Deposit. 

 The Security Deposit may be pledged by Landlord as additional collateral to any lender having a security interest in the Real Property. The
lender may use, apply or retain all or any part of the Security Deposit for the payment of Building Costs, but only in the event that lender shall have notified Landlord and Tenant that such Building Costs remain unpaid and the parties shall have
failed within thirty (30) days following receipt of such notice to cure such nonpayment. For purposes of this Section, “Building Cost(s)” shall mean any and all costs 

  

 42 

 
actually incurred in constructing the Building, Common Area and the related site improvements including, but not limited to, costs for demolition, grading,
utility fees, architectural and engineering fees, permits, surveys, appraisals, insurance, legal and accounting fees, development overhead, construction management, blueprinting, equity fees, construction lender, permanent lender and mortgage banker
fees, interest carry, site improvements, off-site improvements and tenant improvements. If any portion of the Security Deposit is so applied, upon the Phase 1 Rent Commencement Date, Tenant shall deposit cash with Landlord in an amount sufficient to
restore the Security Deposit to its original amount, and Tenant’s failure to do so shall constitute a material breach of this Lease. 
 19.
MISCELLANEOUS. 
 19.1 Notices. 
 All notices, consents, waivers and other communications which this Lease requires or permits either party to give to the other shall be in writing and shall be deemed given when delivered personally (including
delivery by private courier or express delivery service) or three (3) days after deposit in the United States mail, registered or certified mail, postage prepaid, assessed to the parties at their respective addresses as follows:

 or to such other address as may be contained in a notice at least fifteen (15) days prior to the address change from
either party to the other given pursuant to this Section. Rental payments and other sums required by this Lease to be paid by Tenant shall be delivered to Landlord at Landlord’s address provided in this Section, or to such other address as
Landlord may from time to time specify in writing to Tenant, and shall be deemed to be paid only upon actual receipt. 
 19.2 Successors
and Assigns. 
 The obligations of this Lease shall run with the land, and this Lease shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and assigns, except that the original Landlord named herein and each successive Landlord under this Lease shall be liable only for obligations accruing during the period of its ownership of the Real
Property, and any liability for obligations accruing after termination of such ownership shall terminate as of the date of such termination of ownership and shall pass to the successor lessor. 
 19.3 No Waiver. 
 The failure of
Landlord to seek redress for violation, or to insist upon the strict performance, of any covenant or condition of this Lease shall not be deemed a waiver of such violation, or prevent a subsequent act which would originally have constituted a
violation from having all the force and effect of an original violation. 
 19.4 Severability. 
 If any provision of this Lease or the application thereof is held to be invalid or unenforceable, the remainder of this Lease or the application of such
provision to persons or circumstances other than those as to which it is invalid or unenforceable shall not be affected thereby, and each of the provisions of this Lease shall be valid and enforceable, unless enforcement of this Lease as so
invalidated would be unreasonable or grossly inequitable under all the circumstances or would materially frustrate the purposes of this Lease. 
 19.5 Litigation Between Parties. 
 In the event of any litigation or other dispute resolution proceedings between the parties
hereto arising out of or in connection with this Lease, the prevailing party shall be reimbursed for all reasonable costs, including, but not limited to, reasonable accountants’ fees and attorneys’ fees, incurred in connection with such
proceedings (including, but not limited to, any appellate proceedings relating thereto) or in connection with the enforcement of any judgment or award rendered in such proceedings. “Prevailing Party” within the meaning of this
Section shall include, without limitation, a party who dismisses an action for recovery hereunder in exchange for payment of the sums allegedly due, performance of covenants allegedly breached or consideration substantially equal to the relief
sought in the action. 
 19.6 Surrender. 
 A voluntary or other surrender of this Lease by Tenant, or a mutual termination thereof between Landlord and Tenant, shall not result in a merger but shall, at the option of Landlord, operate either as an assignment
to Landlord of any and all existing subleases and subtenancies, or a termination of all or any existing subleases and subtenancies. This provision shall be contained in any and all assignments or subleases made pursuant to this Lease. 
  

 44 

 19.7 Interpretation. 
 The provisions of this Lease shall be construed as a whole, according to their common meaning, and not strictly for or against Landlord or Tenant. The captions preceding the text of each Section and subsection hereof
are included only for convenience of reference and shall be disregarded in the construction or interpretation of this Lease. 
 19.8
Entire Agreement. 
 This written Lease, together with the exhibits hereto, and that certain Redemption Agreement dated as of
June 22, 2004, contains all the representations and the entire understanding between the parties hereto with respect to the subject matter hereof and replaces any prior agreements, including the prior lease, and any prior correspondence,
memoranda or agreements. This Lease may be modified only by an agreement in writing signed by each of the parties. 
 19.9 Governing Law.

 This Lease and all exhibits hereto shall be construed and interpreted in accordance with and be governed by all the provisions of the
laws of the State of California. 
 19.10 No Partnership. 
 The relationship created by this lease between Landlord and Tenant is solely that of a lessor and lessee. Nothing contained in this Lease shall be
construed as creating any type or manner of partnership, joint venture or joint enterprise with or between Landlord and Tenant. Neither party is the agent or representative of the other. 
 19.11 Financial Information. 
 From
time to time Tenant shall promptly provide directly to prospective lenders and purchasers of the Real Property designated by Landlord such financial information pertaining to the financial status of Tenant as Landlord may reasonably request;
provided, Tenant shall be permitted to provide such financial information in a manner which Tenant deems reasonably necessary to protect the confidentiality of such information. In addition, from time to time, Tenant shall provide Landlord
with such financial information pertaining to the financial status of Tenant as Landlord may reasonably request. Landlord agrees that all financial information supplied to Landlord by Tenant shall be treated as confidential material, and shall not
be disseminated to any party or entity (including any entity affiliated, with Landlord) without Tenant’s prior written consent, except that Landlord shall be entitled to provide such information, subject to reasonable precautions to protect the
confidential nature thereof, (i) to Landlord’s partners and professional advisors, solely to use in connection with Landlord’s execution and enforcement of this Lease, and (ii) to prospective lenders and/or purchasers of the Real
Property, solely for use in connection with their bona fide consideration of a proposed financing or purchase of the Real Property, provided that such prospective lenders and/or 

  

 45 

 
purchasers are not then engaged in businesses directly competitive with the business then being conducted by Tenant. For purposes of this Section, without
limiting the generality of the obligations provided herein, it shall be deemed reasonable for Landlord to request copies of Tenant’s most recent audited annual financial statements, or, if audited statements have not been prepared, unaudited
financial statements for Tenant’s most recent fiscal year, accompanied by a certificate of Tenant’s chief financial officer that such financial statements fairly present Tenant’s financial condition as of the date(s) indicated.
Notwithstanding any other provisions of this Section 19.11, during any period in which Tenant has outstanding a class of publicly traded securities and is filing with the Securities and Exchange Commission, on a regular basis, Forms 10Q and 10K
and any other periodic filings required under the Securities Exchange Act of 1934, as amended, it shall constitute sufficient compliance under this Section 19.11 for Tenant to furnish Landlord with copies of such periodic filings substantially
concurrently with the filing thereof with the Securities and Exchange Commission. 
 Landlord and Tenant recognize the need of Tenant to
maintain the confidentiality of information regarding its financial status and the need of Landlord to be informed of, and to provide to prospective lenders and purchasers of the Real Property financial information pertaining to, Tenant’s
financial status. Landlord and Tenant agree to cooperate with each other in achieving these needs within the context of the obligations set forth in this Section. 
 19.12 Costs. 
 Notwithstanding anything to the contrary contained in this Lease, if Tenant requests
the consent of Landlord under any provision of this Lease for any act that Tenant proposes to do hereunder, including, without limitation, assignment or subletting of the Buildings or any portion thereof, Tenant shall, as a condition to doing any
such act and the receipt of such consent, reimburse Landlord promptly for any and all reasonable costs and expenses incurred by Landlord in connection therewith (including, without limitation, reasonable attorneys’ fees) up to a maximum of
$1,000 per request. 
 19.13 Time. 
 Time is of the essence of this Lease, and of every term and condition hereof 
 19.14 Brokers.

 Each party represents and warrants that no other broker participated in the consummation of this Amended and Restated Lease and agrees
to indemnify, defend and hold the other party harmless against any liability, cost or expense, including, without limitation, reasonable attorneys’ fees, arising out of any claims for brokerage commissions or other similar compensation in
connection with any conversations, prior negotiations or other dealings by the indemnifying party with any other person making such claim. 
 19.15 Memorandum of Lease. 
 At any time during the Term of this Lease, either party, at its sole expense, shall be entitled
to record a memorandum of this Lease and, if either party so elects, both parties agree to cooperate in the preparation, execution, acknowledgement and recordation of such document in reasonable form. 
  

 46 

 19.16 Corporate Authority. 
 Each person signing this Lease on behalf of Tenant or Landlord warrants that he or she is fully authorized to do so and, by so doing, to bind the entity

would facilitate the subleasing of Phase 2A; 
 WHEREAS Landlord and Tenant agree that a portion of the Phase 2A Allowance should be used to
construct the Initial Phase 2A Improvements (defined below) and the balance of the Phase 2A Allowance be reserved for future improvements to Phase 2A. 
 AGREEMENT 
 NOW THEREFORE, the parties have entered into this Work Letter to augment and
supplement the Lease as follows: 
 1. Defined Terms. 
 (a) Approved Plans. Plans and specifications to be prepared by the Architect for improvements within Phase 2A as approved by both Landlord and Tenant pursuant to Section 2(a) below, as modified to obtain Building
Permits. 
 (b) Architect. [To be determined] 
 (c) Building Permits. The permits and approvals required to construct the Initial Phase 2A Improvements substantially in compliance with the Approved Plans, obtained pursuant to Section 2(b) below. 
 (d) Completion. Construction of the Initial Phase 2A Improvements shall be deemed completed for purposes of this Work Letter upon the issuance of a
written certificate signed by the Architect certifying that the Initial Phase 2A Improvements have been constructed (except for Punch List Work) in good and workman like condition, in compliance with the Approved Plans and Building Permits, and all
required governmental inspections thereof have been passed. 

 (e) Initial Phase 2A Improvements. The tenant improvements and other improvements within Phase 2A, shown
on the Approved Plans, to be constructed within Phase 2A pursuant to the Lease and this Work Letter, to facilitate the subleasing of Phase 2A. 
 (f) Phase 2A. That portion of the Property defined as Phase 2A in the Lease. 
 (g) Punch List Work. Minor corrections of
construction and minor mechanical adjustments required to cause any applicable portion of the Initial Phase 2A Improvements as constructed to conform to the Approved Plans and Building Permits in all material respects. Landlord shall develop the

 2. Plans and Construction.

 Landlord and Tenant shall comply with the procedures set forth in this Section 2 in preparing, delivering and approving matters
relating to the Initial Phase 2A Improvements. 
 (a) Architect shall develop the scope, plans and specifications for the Initial Phase 2A
Improvements, subject to the supervision of Landlord and the approval of the Tenant, which shall not be unreasonably withheld or delayed. 
 (b) The Approved Plans shall be submitted to the City of San Carlos for approval and issuance of Building Permits. 
 (c) Landlord
shall diligently construct and complete the Initial Phase 2A Improvements substantially in accordance with the Approved Plans and Building Permits. Such construction shall occur in a neat and workmanlike manner and shall materially conform to all
applicable governmental codes, laws and regulations in force at the time such work is completed, 
 (d) Landlord shall spend out of the Phase
2 Allowance not less than $70.00 per Usable Square Foot within Phase 2A, for the Initial Phase 2A Improvements. 
 3. Deadlines:

AND ENFORCEABLE PURSUANT TO CALIFORNIA CIVIL CODE SECTION 1671; (ii) THIS PROVISION IS REASONABLE UNDER THE CIRCUMSTANCES EXISTING AT THE TIME OF EXECUTION OF THIS AGREEMENT; AND (iii) HEREBY WAIVES ANY RIGHTS IT MAY HAVE TO DISPUTE THE
REASONABLENESS OF THIS PROVISION.

 4. Costs of Construction. 
 Except as otherwise agreed between Landlord and Tenant, the cost of construction of the Improvements shall be borne by the Landlord as its sole cost and
expense, including any costs or cost increases incurred as a result of delays, governmental requirements or unanticipated conditions. 
 5.
No Agency. 
 Nothing in this Work Letter shall make or constitute either Landlord or Tenant as the agent of the other. 
 6. Merger. 
 All understandings and
agreements, oral and written, theretofore made between the parties hereto and relating to the matters covered herein are merged in this Work Letter, which, 

  

 3

the agreement between the Landlord and Tenant with regard to the matters set forth in this Work Letter.

 A. WHEREAS, Original Landlord and Tenant entered into that certain Amended and Restated Built-To-Suit Lease dated as of August 17, 2004, as supplemented by that certain Work Letter dated as of August 17,
2004, and as amended by that certain Amendment to Amended and Restated Built-To-Suit Lease dated as of January 11, 2005 (collectively, the “Lease”), whereby Tenant leases certain premises (the “Original

 AGREEMENT 
 NOW, THEREFORE, Landlord and Tenant, in consideration of the mutual promises contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending
to be legally bound, agree as follows: 
 1. Definitions. For purposes of this Amendment, capitalized terms shall have the meanings
ascribed to them in the Lease unless otherwise defined herein. The Lease, as amended by this Amendment, shall be referred to herein as the “Amended Lease.” 
 2. Additional Premises. Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, Suite 420 in Building 1, consisting of
approximately twenty thousand one hundred twenty-three (20,123) rentable square feet of additional premises, as depicted on Exhibit A attached hereto (the “Additional Premises”). The Additional Premises are comprised of
(a) approximately twelve thousand four hundred twenty (12,420) rentable square feet of partially improved space, as depicted on Exhibit B attached hereto (the “Partially Improved Premises”), and
(b) approximately seven thousand seven hundred three (7,703) rentable square feet of shell space, as depicted on Exhibit C attached hereto (the “Shell Premises”). From and after the Additional Premises Commencement

 b. As a portion of, but not in addition to, Tenant’s
Parking, Tenant shall have (subject to (i) the consent of Nuvelo and Landlord’s reasonable consent and (ii) Tenant’s payment of any costs associated therewith, including maintenance), the exclusive right to use the following on

 10. Security Deposit. The Security Deposit is hereby increased by Two Hundred Twenty-Five Thousand
Dollars ($225,000) (the “Additional Security Deposit”) to a total of One Million Six Hundred Thousand Dollars ($1,600,000). Tenant shall either (a) have deposited with Landlord in cash the Additional Security Deposit on or
before the Effective Date, or (b) provide to Landlord within one (1) week of the Effective Date, an amendment to the existing letter of credit presently provided by Tenant as the Security Deposit increasing such letter of credit by the
amount of the Additional Security Deposit. 
 11. Right of First Offer. Tenant shall have a right of first offer (“ROFO”) as
to any additional premises that are available for lease in Building 1 and Building 2 (collectively, the “Option Premises”). In the event Landlord intends to lease all or a portion of the Option Premises (the “Subject
Premises”), Landlord shall provide written notice thereof to Tenant (the “Notice of Offer”). 
 a. Within twenty-one
(21) days following its receipt of a Notice of Offer, Tenant shall advise Landlord in writing whether Tenant elects to lease the Subject Premises, and on what terms and conditions (the “Reply”). If Tenant fails to notify
Landlord of Tenant’s election within such twenty-one (21) day period, then Tenant shall be deemed to have elected not to lease the Subject Premises. 
 b. If Tenant timely notifies Landlord that Tenant elects to lease the Subject Premises, then Landlord and Tenant shall enter into good faith negotiations regarding the terms of a lease of the Subject Premises in
accordance with a Reply. If Landlord and Tenant reach an agreement on the terms of the lease of the Subject Premises, Landlord and Tenant shall work in good faith to execute a lease amendment with respect to such Subject Premises (the “First
Offer Space Amendment”) within thirty (30) days after Landlord’s receipt of the Reply (the “Signing Period”). 
 c. If (i) Tenant notifies Landlord that Tenant elects not to lease the Subject Premises, (ii) Tenant fails to notify Landlord of Tenant’s election within the twenty-one (21) day period described above or (iii) if,
despite good faith efforts to reach an agreement regarding the leasing of the Subject Premises to Tenant, Landlord and Tenant are unable to reach such agreement within the applicable Signing Period, then Landlord shall have the right to consummate a
lease of the Subject Premises with a third party for a period of one (1) year thereafter (a “Leasing Period”), and the ROFO shall no longer apply to such Subject Premises during such Leasing Period; provided that the net
effective rent to be received by Landlord over the term of the lease of the Subject Premises to such third party (the “Third Party Offer”) is at least ninety percent (90%) of the net effective rent that would have been received
by Landlord as set forth in the applicable Reply. If the Third Party Offer is less than ninety percent (90%) of the net effective rent that would have been received by Landlord as set forth in the applicable Reply, Landlord shall re-offer the
Subject Premises to Tenant on the same terms as set forth in the Third Party Offer (a “Re-Offer Notice”) and if (a) Tenant does not deliver a notice electing to lease such Subject Premises on such terms (the “Election
Notice”) within ten (10) days following Tenant’s receipt of the Re-Offer Notice or (b) Tenant delivers such Election Notice, and a First Offer Space Amendment is not executed during the Signing Period applicable to such
re-offer, then Landlord shall be free thereafter for a new Leasing Period to enter into a lease for the Subject Premises on the terms of the Third Party Offer or any new third party offer satisfying the terms and conditions of this
Section 11, and continuing as described above. If Landlord does not lease such Subject Premises within a Leasing Period, then the ROFO with respect to such Subject Premises shall be fully reinstated, and Landlord shall not thereafter
lease such Subject Premises without first complying with the procedures set forth in this Section 11. 
 d. Notwithstanding anything
in this Section 11 to the contrary, Tenant shall not exercise the ROFO during such period of time that Tenant is in default under any provision of the Amended Lease, beyond any applicable notice or cure period. Any attempted exercise of
the ROFO during a period of time in which Tenant is so in default beyond any applicable notice or cure period shall be void and of no effect. In addition, Tenant shall not be entitled to exercise the ROFO if Landlord has given Tenant two (2) or
more notices of default under the Amended Lease, whether or not the defaults are cured, during the twelve (12) month period prior to the date on which Tenant seeks to exercise the ROFO. 
 e. Notwithstanding anything in the Amended Lease to the contrary, Tenant shall not assign or transfer the ROFO, either separately or in conjunction with
an assignment or transfer of 

  

 4 

 
Tenant’s interest in the Lease other than in connection with a Permitted Transfer or to an Affiliate of Tenant in each case in accordance with the terms
of Section 13.1(b) of the Lease, without Landlord’s prior written consent, which consent Landlord may withhold in its sole and absolute discretion. 
 12. Broker. Tenant represents and warrants that it has not dealt with any broker or agent in the negotiation for or the obtaining of this Amendment, other than GVA Kidder Mathews (“Tenant’s
Broker”), and agrees to indemnify, defend and hold Landlord harmless from any and all cost or liability for compensation claimed by any such broker or agent, other than Tenant’s Broker, employed or engaged by it or claiming to have
been employed or engaged by it. Landlord represents and warrants that it has not dealt with any broker or agent in the negotiation for or the obtaining of this Amendment, other than NAIBT Commercial (“Landlord’s Broker”), and
agrees to indemnify, defend and hold Tenant harmless from any and all cost or liability for compensation claimed by any such broker or agent, other than Landlord’s Broker, employed or engaged by it or claiming to have been employed or engaged
by it. Each of Landlord’s Broker and Tenant’s Broker is entitled to a leasing commission in connection with the making of this Amendment, and Landlord shall pay such commission to Landlord’s Broker and Tenant’s Broker pursuant to
a separate agreement between Landlord, Landlord’s Broker and Tenant’s Broker. 
 13. No Default. Tenant represents, warrants
and covenants that, to the best of Tenant’s knowledge, Landlord and Tenant are not in default of any of their respective obligations under the Lease and no event has occurred that, with the passage of time or the giving of notice (or both)
would constitute a default by either Landlord or Tenant thereunder. Landlord represents, warrants and covenants that, to the best of Landlord’s knowledge, Landlord and Tenant are not in default of any of their respective obligations under the
Lease and no event has occurred that, with the passage of time or the giving of notice (or both) would constitute a default by either Landlord or Tenant thereunder. 
 14. Effect of Amendment. Except as modified by this Amendment, the Lease and all the covenants, agreements, terms, provisions and conditions thereof shall remain in full force and effect and are hereby ratified
and affirmed. The covenants, agreements, terms, provisions and conditions contained in this Amendment shall bind and inure to the benefit of the parties hereto and their respective successors and, except as otherwise provided in the Lease, their
respective assigns. In the event of any conflict between the terms contained in this Amendment and the Lease, the terms herein contained shall supersede and control the obligations and liabilities of the parties. From and after the Effective Date,
the term “Lease” as used in the Lease shall mean the Lease, as modified by this Amendment. 
 15. Miscellaneous. This
Amendment becomes effective only upon execution and delivery hereof by Landlord and Tenant. The captions of the paragraphs and subparagraphs in this Amendment are inserted and included solely for convenience and shall not be considered or given any
effect in construing the provisions hereof. All exhibits hereto are incorporated herein by reference.

the cost and expense of such revisions. Tenant Change Order Requests shall be signed by Tenant’s Authorized Representative. 
 (b)
Landlord shall approve or reject any Tenant Change Order Requests in accordance with the procedures established pursuant to Article 2. If Landlord does not approve in writing a Tenant Change Order Request, then such Tenant Change Order

form (a “Landlord Change Order Request”), which Landlord Change Order Request shall detail the nature and extent of any requested Changes. If the nature of a Change requires revisions to the Approved Plans, then Landlord shall be
solely responsible for the cost and expense of such revisions. Landlord shall reimburse Tenant for all additional costs and expenses payable by Tenant to complete Tenant’s Work due to a Landlord-requested Change in accordance with the payment
provisions of this Work Letter. 
 8.3. Preparation of Estimates. Tenant shall, before proceeding with any Change, using its best
efforts, prepare as soon as is reasonably practicable (but in no event more than five (5) business days after delivering a Tenant Change Order Request to Landlord or receipt of a Landlord Change Order Request) an estimate of the increased costs
or savings that would result from such Change, as well as an estimate on such Change’s effects on the Schedule. Landlord shall have ten (10) business days after receipt of such information from Tenant to (a) in the case of a Tenant
Change Order Request, approve or reject such Tenant Change Order Request in writing, or (b) in the case of a Landlord Change Order Request, notify Tenant in writing of Landlord’s decision either to proceed with or abandon the
Landlord-requested Change.
