Exhibit 10.16



GROUND LEASE



THIS LEASE is made and entered into as of June 25, 2003 (the Commencement Date), by and between THE BOARD OF TRUSTEES OF THE
LELAND STANFORD JUNIOR UNIVERSITY, a body having corporate powers under the laws of the State of California (Lessor), and 3301 HILLVIEW HOLDINGS, INC., a Delaware corporation (Lessee).



RECITALS



A. Lessor owns that certain real property commonly known as 3301-3307
Hillview Avenue, Palo Alto, California, and more particularly described in the attached Exhibit A(the Land).



B. Lessor and Lessee are the parties to that certain Agreement to Lease and Sell Assets dated as of June 2, 2003 (the Agreement to
Lease), whereby Lessee has purchased (subject to this Lease) all of the improvements on the Land, including all buildings, structures, systems, facilities and fixtures located on the Land, and any and all machinery, equipment,
apparatus and appliances (not owned by subtenants) incorporated into the foregoing and used in connection with the operation or occupancy of the Land, but excluding the Remediation Systems (collectively, the Improvements).



C. Lessee now desires to lease the Land from Lessor, and
Lessor desires to lease the Land to Lessee on the terms and conditions and for the purposes set forth in this Lease.



D. Because Lessees ownership of the Improvements is subject to this Lease and will revert to Lessor upon the expiration or earlier termination of
this Lease, the terms and conditions of this Lease shall also apply to the Improvements. Collectively, the Land and Improvements are referred to herein as the Premises. The Premises does not include any leasehold interest
in the Pre-Existing Environmental Condition or in any Remediation Systems located on the Premises, all of which are owned by third parties.



E. Lessor and Lessee are also the parties to that certain lease dated as of September 24, 1999 (the Prior Lease), pursuant to
which Lessee has been the sole tenant of the Premises since construction of the Improvements. As of the Commencement Date, the Prior Lease is hereby terminated; provided, however, that all of the obligations of Lessee and Lessor which by the terms
of the Prior Lease survive the termination of the Prior Lease, and also any obligations which survive as a matter of Applicable Law, shall survive during the term of this Lease, notwithstanding the expiration of any applicable statute of
limitations.



NOW, THEREFORE, in consideration of the rents to
be paid hereunder and of the agreements, covenants and conditions contained herein, the parties hereby agree as follows:

Fair Market Rental Value as determined from time to time, means the average
arms-length fair market annual triple net rental rate per rentable square foot during the three (3) year period preceding the time of such determination for new leases and renewal leases of space comparable to space within the Improvements on the
Premises (in terms of rentable square footage, physical quality (including that of any existing leasehold improvements in such comparable space that are reasonably reuseable by a new tenant), views, floor levels, location and other matters) in
buildings in the Stanford Research Park. The determination shall take into account any material economic differences between the terms of this Lease and any comparison lease, such as the presence or absence of the obligation to pay a leasing
commission, base years, the load factor for the applicable spaces, the length of the term for such leases, rent abatements, tenant improvement obligations, free rent periods, moving allowances, design allowances, the manner (if any) in which the
landlord under any such lease is reimbursed for operating expenses and taxes, and any other concessions. The parties acknowledge that it is their intention that Fair Market Rental Value be an average value based on leasing transactions entered into
over the three (3) year period preceding the date of determination in order to avoid unusual or relatively brief highs and lows in market rents. In addition, the parties acknowledge that as of the Commencement Date it is the custom for comparable
buildings in the Stanford Research Park to be leased to space tenants on a so-called triple net basis (i.e., the tenant pays a fixed minimum rent, typically subject to periodic increases, which is the triple net rent, and in
addition the tenant also pays, or reimburses the landlord for, operating expenses of the property in question, including without limitation real property taxes, insurance, maintenance, repair, and management, which latter payments or reimbursements
are not part of the triple net rent). The parties agree that the Fair Market Rental Value of the Premises shall be determined and expressed as a triple net rent value. Accordingly, if any leasing transaction is utilized as a
comparable transaction in the determination of Fair Market Rental Value and such leasing transaction is not structured as a so-called triple net lease, the rent payments due under such lease shall be adjusted and converted to a
triple net rent value so that it is truly comparable to the triple net rent value that was initially used in establishing the Base Rent due as of the Commencement Date. In determining Fair Market Rental Value, the parties
shall disregard any sublease of the Premises by any Affiliate of Lessee. In the event the parties cannot agree as to the Fair Market Rental Value after thirty (30) days of good faith negotiations, Fair Market Rental Value shall be determined
pursuant to the process described in Exhibit B.



First Class means having a standard of condition, maintenance, repair and operation at least equal to comparable Class A properties in Santa Clara County as of the Commencement Date.

(a) Lessor hereby reserves the right of Lessor, at all reasonable times and, following reasonable advance notice to Lessee,
to enter and to permit the City, the County of Santa Clara, the Santa Clara Valley Water District, other governmental bodies, public or private utilities and any other persons or entities authorized by Lessor to enter upon the Premises for the

(b) Lessor hereby retains the sole and exclusive right to enter upon the
Premises to mine or otherwise produce or extract by any means whatsoever, whether by slant drilling or otherwise, oil, gas, hydrocarbons and other minerals (of any character) in or under or from the Premises, such mining, production or extraction to
be for the sole benefit of Lessor without obligation to pay Lessee for any or all of the substances so mined, produced or extracted; provided, however, that none of the operations for such mining, production or extraction shall be conducted from or
within 100 feet of the surface of the Premises, but only at such depth beneath the surface as not to interfere with the use of the Premises or the stability of any Improvements on the Premises.



(c) Lessor shall be entitled, at all reasonable times and upon reasonable
notice, to go upon and into the Premises and the Improvements for the purposes of (i) inspecting the same; (ii) inspecting the performance by Lessee of the terms, covenants, agreements and conditions of this Lease; (iii) posting and keeping posted

of the Premises, and shall not materially adversely affect any Improvements on, or the use, operation or value of the Premises. All of Lessors activities pursuant to this Section shall be at Lessors sole cost and expense. Lessor shall
repair any damage to the Premises caused by such activities, and shall keep the Premises free of mechanics or materialmens liens arising as a result thereof. Except to the extent of Lessors breach of this Lease, violation of

the Premises, any loss of occupancy or quiet enjoyment or the Premises or any other loss, damage, liability or cost occasioned by Lessors exercise of the rights reserved to Lessor under, or granted to Lessor pursuant to this Section. In no

(e) Lessee hereby acknowledges that, as owner and in the best interests of the Stanford Research Park, Lessor may find it necessary or convenient from time to time to apply for entitlements, seek rezoning, or
otherwise endeavor to negotiate agreements with the governmental entities having jurisdiction over the Stanford Research Park; provided, however, that Lessor shall not take any action which disproportionately burdens the Premises as compared to
other properties in the Stanford Research Park. Lessee agrees that so long as Lessors efforts (i) do not have a material adverse impact on Lessees investment in, or the use, operation, value or marketability of the Premises, or (ii) do
not discriminate against the Premises or disproportionately burden the Premises as compared to other properties in the Stanford Research Park, Lessee shall not publicly oppose or object to any such efforts by Lessor. In the event of any dispute
arising pursuant to this Section 3.2(e), such dispute shall be resolved by arbitration pursuant to Article 36.

Section 4.2 Acceptance of the Premises. Lessee acknowledges that, Lessor has made no representations or warranties, express or implied, regarding the Premises or matters affecting the Premises, whether made by Lessor, on
Lessors behalf or otherwise, including, without limitation, the physical condition of the Premises, title to, or the boundaries of the Premises, pest control matters, soil conditions, the presence, existence or absence of Hazardous Substances

the Premises, or any other matter pertaining to the Premises or the market and physical environments in which the Premises are located. Lessee acknowledges: (a) Lessee is a sophisticated real estate investor with sufficient experience and expertise
to evaluate the Premises and the operations conducted on the Premises and the risks associated with acquiring a leasehold interest in the Premises upon the terms and conditions set forth herein, (b) Lessee has received sufficient information and had
adequate time to make such an evaluation, and has occupied and managed the Premises under the Prior Lease since April 2002, (c) Lessee has entered into this Lease with the intention of relying upon its own investigation and knowledge with respect to
the physical, environmental, economic and legal condition of the Premises, (d) in connection with its investigations and inspections of the Premises it has contracted with certain advisors and consultants, including but not limited to environmental
consultants, engineers and geologists, soils and seismic experts, to conduct such environmental, geological, soil, hydrology, seismic, physical, structural, mechanical and other inspections of the Premises as Lessee deemed to be necessary, and that
Lessee has reviewed thoroughly all such reports as well as all materials and other information given or made available to Lessee by Lessor, and (e) Lessee is not relying upon any statements, representations or warranties of any kind. Lessee further
acknowledges that it has not received from or on behalf of Lessor any accounting, tax, legal, architectural, engineering, property management or other advice with respect to this transaction and is relying solely upon the advice of third party
accounting, tax, legal, architectural, engineering, property management and other advisors. Lessee has satisfied itself as to such suitability and other pertinent matters by Lessees own inquiries and tests into all matters relevant in
determining whether to enter into this Lease. Lessee accepts the Premises in its existing condition and hereby expressly agrees that if any remedial or restoration work is required in order to conform the Premises to the requirements of Applicable
Laws, Lessee shall assume sole responsibility for any such work. Lessee is acquiring on the Commencement Date a leasehold interest in the Premises in its AS IS condition and WITH ALL FAULTS.Notwithstanding the
foregoing, to the extent that Lessor has made express representations in writing contained either in the Agreement to Lease or in this Lease, the foregoing provisions of this Section 4.2 shall not apply to such express representations. Lessee shall
be entitled to rely on such representations, and Lessor shall be responsible for any inaccuracy contained in such representations. In addition, the foregoing provisions of Section 4.2 are subject to Article 18 and shall not affect or modify any
provisions of Article 18 or of the Agreement to Lease which are to be performed

after the Commencement Date or which survive the Commencement Date, such as Lessors agreement to perform certain repair and corrective work following
the Commencement Date that is set forth in the Agreement to Lease.



ARTICLE 5.

TERM



The term of this Lease (the Term) shall be for the period stated in the Basic Lease Information, commencing on the Commencement
Date and expiring on the Expiration Date or on such earlier date as this Lease may be terminated as hereinafter provided.



ARTICLE 6.

BASE RENT



Section 6.1 Base Rent.



(a) Beginning on the Commencement Date, and on the first day of each
calendar month during the Term, Lessee shall pay to Lessor the monthly base rent (Base Rent) specified in Article 1 at the address for Lessor set forth in Article 1, or at such other place as Lessor shall designate, without
any prior demand therefor and without any deduction or offset whatsoever, which amount shall be adjusted as provided in subsection (b) below. Base Rent shall be prorated for any partial months at the beginning or end of the Term.



(b) Base Rent shall be increased by three percent (3%) per annum as of each
anniversary of the Commencement Date throughout the Term, except during years in which Base Rent is reset, as provided in this subsection. On April 25, 2014, and on April 25 every tenth (10th) year thereafter (each a Rent Reset Date), Base Rent shall be reset to equal twenty-five percent (25%) of Fair Market Rental Value;
provided, however, that in no event shall the adjusted Base Rent set on any Rent Reset Date be less than ninety percent (90%) of the Base Rent for the month prior to the applicable Rent Reset Date.



(c) No later than ninety (90) days prior to each Rent Reset Date, Lessor
shall send to Lessee its good faith proposal as to what the Fair Market Rental Value, the Decennial Rent Increase and the Unpaid Base Rent Portion (as both are defined in Section 6.2(a) below), if any, shall be as of that Rent Reset Date.
Lessors proposal shall also include (i) a reasonable explanation of the basis for its proposal; and (ii) its good faith estimate of the amount Lessee would be required to pay if Lessee were to elect, as of that Rent Reset Date, to prepay the
Unpaid Base Rent Portion, together with the allocable 3% Annual Increases and taking into account any other requirements or adjustments set forth in Sections 6.1 and 6.2, for the remainder of the Term. Within ten (10) days after receipt of
Lessors proposal, Lessee shall either accept Lessors proposal in writing or enter into discussions with Lessor regarding the proposal. If Lessor and Lessee are unable to agree upon the Fair Market Rental Value, the Decennial Rent
Increase or the Unpaid Base Rent Portion at least seventy (70) days prior to the relevant Rent Reset Date, the matter shall be submitted for determination by appraisal in accordance with Exhibit B. If Lessee elects not to prepay the
Unpaid Base Rent Portion, as calculated and agreed or established, on or before the relevant Rent Reset Date, then Lessee may



13



---

do so at a later date in accordance with Section 6.2(c). Failure by Lessor to notify Lessee pursuant to this subsection (c) shall not constitutes a waiver of
Lessees obligation to pay the adjusted Base Rent as provided in Section 6.1(b).



Section 6.2 Prepayment of Base Rent.



(a) For purposes of the application of this Section, the following terms shall have the following meanings: (i) the Base Rent initially due in the amount of One Hundred Forty-Six Thousand Six and 50/100 Dollars
($146,006.50) per month is referred to herein as the Initial Base Rent; (ii) the increases to Base Rent of 3% per annum as of each anniversary of each Commencement Date throughout the Term, except during years in which Base
Rent is reset, as required by Section 6.l(b), are referred to herein as the 3% Annual Increases; and (iii) the term Decennial Rent Increase refers to the rent adjustments that are required to be
made on each Rent Reset Date pursuant to Section 6.l(b). The parties acknowledge that as of the Commencement Date, Lessee has paid to Lessor, as prepayment of Base Rent, the amount of Twenty-Eight Million Dollars ($28,000,000), which is in full
satisfaction of Lessees obligation to pay that portion of the Base Rent which is the Initial Base Rent and all 3% Annual Increases allocable to the Initial Base Rent for the entire Term of fifty-one (51) years (the Initial
Prepayment). Accordingly, the Initial Prepayment fully satisfies Lessees obligation to pay Base Rent for the period beginning as of the Commencement Date and ending on the first Rent Reset Date, and also satisfies a portion of
Lessees obligation to pay Base Rent for the period beginning on the first Rent Reset Date and continuing throughout the remainder of the Term. With respect to each Decennial Rent Increase that is required to be made effective as of a Rent
Reset Date, the parties shall determine the difference between (i) the Initial Base Rent, as adjusted by the 3% Annual Increases, that has been prepaid and relates to the annual period immediately preceding the Rent Reset Date in question, and (ii)
the Base Rent established by the Decennial Rent Increase for the annual period immediately following the Rent Reset Date in question (which difference is referred to herein as the Unpaid Base Rent Portion). Notwithstanding
anything else set forth in this Article 6, the parties acknowledge that the Initial Prepayment calculation did not reflect the possible adjustment of Base Rent at a Rent Reset Date to ninety percent (90%) of the prior years Base Rent, as
provided in Section 6.1(b). Instead, the Initial Prepayment calculation assumed that the Base Rent would remain the same as the prior years Base Rent. Therefore, in calculating the Unpaid Base Rent Portion, the Decennial Rent Increase shall
take that assumption and its resulting calculation into account, as shown on Schedule 6.2. For the remaining Term of this Lease following the Rent Reset Date in question, Lessee shall pay on account of Base Rent that portion which has
not been prepaid, which is the Unpaid Base Rent Portion plus all 3% Annual Increases allocable to such Unpaid Base Rent Portion, until otherwise adjusted on successive Rent Reset Dates. If it is determined that in making the Initial Prepayment,
Lessee overpays Base Rent due for a later period because on a Rent Reset Date twenty-five percent (25%) of the Fair Market Rental Value is less than the Base Rent due for the month prior to the applicable Rent Reset Date, then Lessor shall not be
obligated to refund any such overpayment of prepaid Base Rent to Lessee.



(b) By way of example only, Schedule 6.2 sets forth an example of how the Unpaid Base Rent Portion and the 3% Annual Increases allocable thereto would be calculated, if the following assumptions prove to
be true. On the first Rent Reset Date, if the Fair Market



14



---

Rental Value is equal to $4.00 per rentable square foot per month, the Unpaid Base Rent Portion would be reset to $95,792 per month, and the Unpaid Base Rent
Portion would be subject to the 3% Annual Increases as set forth in Schedule 6.2.



(c) At any time within two (2) years after each Rent Reset Date, Lessee shall have the option, but not the obligation, to prepay the Unpaid Base Rent
Portion and all 3% Annual Increases allocable thereto for the remainder of the Term or any lesser period designated by Lessee (the Elected Prepayment Period) by notifying Lessor in writing of such election once the final
determination (by agreement or by appraisal pursuant to Exhibit B) of the Unpaid Base Rent Portion due after the Rent Reset Date in question has been made. The amount of the prepayment shall be equal to the present value of all
payments of the Unpaid Base Rent Portion and the 3% Annual Increases allocable thereto that are due for the Elected Prepayment Period, which present value shall be calculated using an annualized discount rate equal to the sum of 400 basis points,
plus the Applicable Long-Term Government Bond Rate (as defined in Section 6.2(d)). In determining the amount of such prepayment, the Base Rent for the Rent Reset Date immediately preceding the prepayment shall be determined
in accordance with Section 6.1(b), but the Decennial Rent Increase for each subsequent Rent Reset Date shall be based on the assumption that for each such subsequent Rent Resent Date, 25% of Fair Market Rental Value is less than 90% of the Base Rent
due for the month prior to the applicable Rent Reset Date so that the monthly Base Rent for the annual period following each such subsequent Rent Reset Date is 90% of the Base Rent due for the month preceding such Rent Reset Date. If Lessee
exercises such option to make such prepayment, it shall pay the appropriate prepayment amount to Lessor within thirty (30) days after the date Lessee has notified Lessor of its exercise of such option. Once such prepayment has been made, Lessee
shall be deemed to have satisfied its obligation to pay all Base Rent for the Elected Prepayment Period in question.



(d) As used herein, the term Applicable Long-Term Government Bond Rate shall be the yield-to-maturity of the non-callable U.S. Treasury Bond
with a maturity closest to the end of the Elected Prepayment Period in question, averaged over the twelve (12) month period prior to such Elected Prepayment Period, using the rates published by a reputable external source selected by Lessee and
approved by Lessor, which approval shall not be unreasonably withheld. If at the time Lessee exercises an option to prepay rent, the applicable maturities are no longer available to be used as a basis for the calculation required by Section 6.2(c),
Lessor and Lessee shall cooperate in good faith to select a different index or instrument to effect the calculation for which the Applicable Long-Term Government Bond Rate is utilized that would result in substantially the same effect and result as
the Applicable Long-Term Government Bond Rate. In the event Lessor and Lessee cannot reach agreement upon such an index or instrument within a reasonable period of time, the dispute shall be settled by arbitration conducted in accordance with
Article 36.



(e) By way of example only, if all of the
assumptions and results regarding Base Rent set forth in the first example stated in Schedule 6.2 are assumed to be true, and if Lessee timely exercises its option to prepay the Unpaid Base Rent Portion and the 3% Annual Increases
allocable thereto for the remaining Term of the Lease following the first Rent Reset Date of April 25, 2014, and if it is further assumed that the Applicable Long-Term Government Bond Rate for the appropriate 30-year maturity is 6% and that the
resulting discount rate to be used for



15



---

the calculations of the prepayment amount is that amount plus 400 basis points (or a total of l0%), then Lessee would have to pay Eleven Million Six Hundred
Ninety-Seven Thousand Eight Hundred Fifty-One Dollars ($11,697,851) as the prepaid amount to fully satisfy its obligation to pay the Unpaid Base Rent Portion and the 3% Annual Increases allocable to the remaining Term of this Lease following the
first Rent Reset Date of April 25, 2014.



Section 6.3 Late
Payments. Any unpaid Rent hereunder shall bear interest from the date which is five (5) days after the date the same is due until paid at the Interest Rate. In addition, Lessee recognizes that late payment of any Rent due hereunder will result
in administrative expense to Lessor, the extent of which expense is difficult and economically impracticable to determine. Therefore, Lessee agrees that if Lessee fails to pay any Rent within five (5) days after the date the same is due and payable,
an additional late charge of five percent (5%) of the sums so overdue shall become immediately due and payable. Lessee agrees that the late payment charge is a reasonable estimate of the additional administrative costs and detriment that will be
incurred by Lessor as a result of such failure by Lessee. In the event of nonpayment of interest or late charges on overdue Rent, Lessor shall have, in addition to all other rights and remedies, the rights and remedies provided herein and by law for
nonpayment of rent.



ARTICLE 7.

ADDITIONAL RENT



Section 7.1 Additional Rent. Each and every sum payable to Lessor pursuant to this Lease (other than Base Rent), each and every sum Lessee is
obligated to pay to any third party pursuant to this Lease, and each and every sum which Lessor pays to any third party to cure a default of Lessee under this Lease shall be additional rent (Additional Rent).



Section 7.2 Property Taxes. Without limiting the foregoing, Additional
Rent shall include, and Lessee agrees to bear, discharge and pay to the relevant authority or entity, in lawful money of the United States, without offset or deduction, as the same become due, and before delinquency, all taxes, assessments, rates,
charges, license fees, municipal liens, levies, excises or imposts, whether general or special, or ordinary or extraordinary, of every name, nature and kind whatsoever, including all governmental charges of every name, nature or kind that may be
levied, assessed, charged or imposed or may be or become a lien or charge upon the Premises or any part thereof; or upon the rent or income of Lessee; or upon the use or occupancy of the Premises; or any document creating or transferring an estate
or interest in the Premises; upon any of the buildings or improvements that are or are hereafter placed, built or newly constructed upon the Premises; or upon the leasehold of Lessee or upon the estate hereby created; or upon Lessor by reason of its
ownership of the fee underlying this Lease; provided, however, that Lessee shall have no obligation to pay or reimburse Lessor for any franchise, transfer, inheritance, or capital stock taxes or income taxes measured by the net income of Lessor or
any taxes arising as a consequence of or in connection with any Pre-Existing Environmental Condition. If at any time during the Term, under any Applicable Laws, any tax is levied or assessed against Lessor directly, in substitution in whole or in
part for real property taxes, Lessee covenants and agrees to pay and discharge such tax so long as such tax is then customarily paid or reimbursed by tenants under long-term ground leases and/or by tenants under commercial triple net
space leases. Lessees obligations described above include, but are not limited to, the payment of any bonds or



16



---

charges imposed or required by any governmental agency or department with respect to the Premises, by reason of the proposed or actual use, treatment,
storage, discharge, cleanup or disposal, or oversight thereof, of Hazardous Substances by any governmental agency, Lessee, or any subtenant, tenant or licensee claiming through Lessee; provided, however, that this provision shall not, and shall not
be deemed to, permit Lessee to use, treat, store or dispose of any such substances on the Premises-nor shall it make Lessee responsible for any taxes arising as a consequence of or in connection with any Pre-Existing Environmental Condition. All of
the foregoing taxes, assessments and other charges which are the responsibility of Lessee are herein referred to as Property Taxes.



Section 7.3 Payment. Lessee shall obtain and deliver to Lessor, promptly upon request therefor, satisfactory evidence of payment of all Property
Taxes.



Section 7.4 Right to Contest. Lessee shall have
the right to contest, by appropriate proceedings, the amount or validity, in whole or in part, of any Property Taxes. In the event the applicable taxing authority having jurisdiction over the contest proceedings allows the posting of security or
some other method of deferring payment of the disputed Property Taxes, Lessee may do so; otherwise Lessee shall not postpone or defer payment of any disputed Property Taxes but shall pay such Property Taxes in accordance with Section 7.2
notwithstanding such contest. Lessor shall have no obligation to join in any such proceedings. Lessee shall indemnify and defend Lessor against and hold Lessor harmless from and against any and all claims, demands, losses, costs, liabilities,
damages, penalties and expenses, including, without limitation, reasonable attorneys fees and expenses, arising from or in connection with any such proceedings.



Section 7.5 Proration. Any Property Taxes relating to a fiscal period of any taxing authority, only a part of which
period is included within the Term, shall be prorated as between Lessor and Lessee so that Lessor shall pay the portion thereof attributable to any period outside the Term, and Lessee shall pay the portion thereof attributable to any period within
the Term.



Section 7.6 Assessment Proceedings. If at any
time during the Term any governmental authority shall undertake to create an improvement or special assessment district, the proposed boundaries of which shall include the Premises (the Proposed District), Lessee shall be
entitled to appear in any proceeding relating thereto and to exercise all rights of a landowner to have the Premises excluded from the Proposed District, or to determine the degree of benefit to the Premises resulting therefrom. However, Lessor
retains the independent right, but shall be under no obligation, to appear in any such proceeding for the purpose of seeking inclusion of the Premises in, or exclusion of the Premises from, any Proposed District or of determining the degree of
benefit therefrom to the Premises; provided, however, that Lessor shall not exercise such right if to do so would disproportionately burden the Premises as compared to other properties in the Stanford Research Park. The party receiving any notice or
other information relating to the Proposed District shall promptly advise the other party in writing of such receipt. If the Proposed District is ultimately formed and affects the Premises, Lessee may pay any resulting bonds over the maximum period
allowed by law, and shall be liable only for any installments that become due during the Term.



17



---

Section 7.7 Transit Fees. Without limiting the foregoing, Additional Rent shall also include and
Lessee agrees to bear, discharge and pay, in lawful money of the United States, without offset or deduction, its proportionate share of the reasonable cost of any transit services or traffic mitigation programs which Lessor implements in the
Stanford Research Park, including without limitation charges for service and surcharges imposed on the Premises by any governmental agencies on or with respect to transit (including transit services which may be provided in the future to occupants
of the Stanford Research Park) or automobile usage or parking facilities (collectively, Transit Fees). Lessees share of Transit Fees shall be assessed pro rata and on a non- discriminatory basis, based on a reasonable
standard applied in a non-discriminatory manner by Lessor (for example, based on the rentable area of the Improvements as compared to the total rentable area of the Stanford Research Park, or based on the average employee headcount in the Premises
as compared to the overall employee density of the Stanford Research Park).



ARTICLE 8.

NET LEASE; NO COUNTERCLAIM OR ABATEMENT



Section 8.1 Net Lease. The Rent due hereunder shall be absolutely net
to Lessor and shall be paid without assertion of any counterclaim, offset, deduction or defense and without abatement, suspension, deferment or reduction. Lessor shall not be expected or required under any circumstances or conditions whatsoever,
whether now existing or hereafter arising, and whether now known or unknown to the parties, to make any payment of any kind whatsoever with respect to the Premises or be under any obligation or liability hereunder, except as expressly set forth in
this Lease.



Section 8.2 No Release. Except as otherwise
expressly provided herein, this Lease shall continue in full force and effect, and the obligations of Lessee hereunder shall not be released, discharged or otherwise affected, by reason of: (a) any damage to or destruction of the Premises or any
portion thereof or any Improvements thereon, or any Appropriation; (b) any restriction or prevention of or interference with any use of the Premises or the Improvements or any part thereof; (c) any bankruptcy, insolvency, reorganization,
composition, adjustment, dissolution, liquidation or other proceeding relating to Lessor, Lessee or any constituent partner of Lessee or any sublessee, licensee or concessionaire or any action taken with respect to this Lease by an trustee or
receiver, or by any court, in any proceeding; (d) any claim that Lessee or any other person has or might have against Lessor; (e) any failure on the part of Lessor to perform or comply with any of the terms hereof or of any other agreement with
Lessee or any other person; (f) any failure on the part of any sublessee, licensee, concessionaire, or other person to perform or comply with any of the terms of any sublease or other agreement between Lessee and any such person; (g) any termination
of any sublease, license or concession, whether voluntary or by operation of law; or (h) any other occurrence whatsoever, whether similar or dissimilar to the foregoing, in each case whether or not Lessee shall have notice or knowledge of any of the
foregoing.



Section 8.3 Independent Covenants, Waiver.
Lessees obligations hereunder shall be separate and independent covenants and agreements. Each agreement of Lessee shall be both a covenant and a condition. Lessee hereby waives, to the full extent permitted by applicable law,



18



---

all rights now or hereafter conferred by statute, including without limitation the provisions of Civil Code Sections 1932 and 1933, to quit, terminate or
surrender this Lease or the Premises or any part thereof, or to any abatement, suspension, deferment, diminution or reduction of any Rent payable hereunder.



ARTICLE 9.

USE AND OPERATION OF
PREMISES



Section 9.1 Use Restriction. Except as
otherwise specifically permitted in this Section 9.1 or in Section 9.2, the Premises may only be used and operated for research and development uses, which for the purposes of this Lease means uses primarily related to the study,
testing, engineering, design, analysis and experimental development of products, processes, or services related to current or new technologies. Research and development may include limited manufacturing, fabricating, processing, assembling or
storage of prototypes, products or materials, or similar related activities, where such activities are incidental to research, development or evaluation. Examples of research and development uses include, but are not limited to, computer software
and hardware firms, electronic research firms, biotechnical firms, medical device firms, and pharmaceutical research laboratories. Related administrative uses, such as (a) finance, marketing, sales, accounting, purchasing, or corporate offices, (b)
provisions of services to others on or off-site, and (c) related educational uses, may also be included provided they remain supportive to the primary uses of research and development and are part of the same research and development firm. Related
administrative uses may constitute up to ninety percent (90%) of the building area within the Premises so long as at least ten percent (10%) of such building area is devoted to the primary uses of research and development. Where a single firm
operates on more than one site within the Research Park, the multiple sites may be treated as a single site for determining the primary use. Collectively, the activities described above in this Section are referred to herein as the
Permitted Use. The parties hereby acknowledge and agree that Lessees covenant that the Premises may only be used for the Permitted Use and for no other purpose is material consideration for Lessors agreement to
enter into this Lease. The parties further acknowledge and agree that any violation of said covenant shall constitute a material breach of this Lease and entitle Lessor to exercise any and all of its rights and remedies under this Lease or otherwise
at law or in equity.



Section 9.2 Compliance with Permitted
Use. Notwithstanding anything contained in Section 9.1, at any time, up to twenty percent (20%) of the area of the Premises may be used for office uses which do not comply with the Permitted Use described in Section 9.1 above (e.g.,
service office use (such as law firms or financial services firms), or administrative office use by any occupant whose business does not meet the definition of research and development described in Section 9.1).
Notwithstanding the foregoing, the parties acknowledge that as of the Commencement Date, the City is in the process of updating its zoning ordinance, and is considering a limitation on office uses in the Stanford Research Park. It is possible that
any such limitation would apply not only to service office uses, but also to administrative office uses associated with research and development businesses, and that such limitation would apply on a company-by-company basis, making any
excess administrative office use by Lessee (beyond a stated percentage of the total square footage) non-compliant with the revised zoning ordinance. In such event, so long as Lessee is in compliance with Section 9.1, Lessor shall allocate to the



19



---

Premises sufficient office space square footage out of the total City-imposed office limitation for the Stanford Research Park to allow Lessee to utilize the
building area within the Premises in accordance with the limitations and allocations of area permitted by Sections 9.1 and 9.2.



Section 9.3 Founding Grant. Notwithstanding any other provision of this Lease, Lessees use of the Premises shall at all times comply with the
requirements and restrictions of the Grant of Endowment of the Leland Stanford Junior University (the Founding Grant), and all subsequent amendments thereto; provided that, Lessee shall not be in breach of this Lease due to
any subsequent amendment of the Founding Grant which conflicts or is inconsistent with the terms and conditions of this Lease, unless the applicable amendment occurs through a legislative or judicial act. Lessor warrants that the Permitted Use is
not prohibited by the Founding Grant.



Section 9.4
Prohibited Uses. Without limiting the foregoing, or any other provision of this Lease, in no event shall the Premises be used for any purpose that (a) in any manner causes, creates, or results in a nuisance or waste; or (b) is of a nature
to involve substantial hazard, such as the manufacture or use of explosives, chemicals or products that may explode, or that otherwise may harm the health or welfare of persons or the physical environment; or (c) involves any Release of Hazardous
Substances in violation of any Environmental Requirements.



Section 9.5 Impacts on Lessors Other Property. Lessee shall maintain the Premises and manage its operations within the Premises so as to avoid any material negative impact from the appearance of the Premises or any of its
operations on the other tenants and properties located in the Stanford Research Park.



Section 9.6 Lockheed Easement. As of the Commencement Date, Lessor and Lessee intend to jointly grant a storm drain easement to Lockheed Martin Corporation, the lessee of property adjacent to the Premises.
Lessee agrees that it shall assume responsibility during the Term for all of the obligations of the grantors under such easement, and Lessor agrees that so long as Lessee is performing such obligations, Lessee shall have the sole and exclusive right
to seek reimbursements from the grantee which may be applicable under such easement.



ARTICLE 10.

LIMITATION ON EFFECT OF APPROVALS



All rights of Lessor to review, comment upon, approve, inspect or take any
other action with respect to the Premises, or the design or construction of any Alteration to the Premises, or any other matter, are specifically for the benefit of Lessor and no other party. Lessor neither has nor assumes any liability,
responsibility or obligation for, in connection with, or with respect to, any such approvals, and no review, comment, approval or inspection, right or exercise of any right to perform Lessees obligations, or similar actions required or
permitted by, of, or to Lessor hereunder, or actions or omissions of Lessors Agents, or other circumstances shall give or be deemed to give Lessor any such liability, responsibility or obligation.

ARTICLE 11.

IMPROVEMENTS, CONSTRUCTION OF ALTERATIONS



Section 11.1 Improvements. Lessor and Lessee hereby acknowledge that the conveyance of the Improvements pursuant to the Agreement to Lease is subject to this Lease and the Improvements will revert to Lessor
upon the expiration or earlier termination of this Lease.



Section 11.2 Additional Improvements and Alterations.



(a) Lessee shall have the right to construct additional Improvements on the Premises and to make Alterations to the existing Improvements (collectively Additional Improvements and Alterations); provided, however,
that if any such Additional Improvements and Alterations (i) are reasonably expected to cost in excess of Five Hundred Thousand Dollars ($500,000) (subject to adjustment during the Term to reflect changes in the CPI); (ii) relate in whole or in part
to any Lessee Environmental Activity; (iii) affect the structural integrity of the Premises or any part thereof; (iv) materially affect the exterior appearance of the Premises, (v) require any health, safety or environmental approval or any
application to a political jurisdiction for rezoning, general plan amendment, variance, conditional use permit or City Architectural Review Board approval (it being the intention that the foregoing approvals are for matters that require the
discretionary approval of a governmental authority, and do not include approvals for matters which are ministerial acts of governmental authorities, such as the issuance of building permits and certificates of occupancy, and any inspections done in
connection with or satisfying requirements related to the issuance of building permits and certificates of occupancy); or (vi) require Lessors approval pursuant to any other provision of this Lease, then such proposed Additional Improvements
and Alterations shall be subject to Lessors prior written approval.



(b) Notwithstanding the foregoing, item (i) of subparagraph (a) of this Section 11.2 shall not apply to interior, non-structural Alterations to the Premises and Lessors prior written approval of any interior,
non-structural Alterations shall only be required if such Alterations would otherwise require approval under items (ii) through (v) of subparagraph (a). With respect to interior non-structural Alterations, Lessee shall have broad flexibility to
modify, alter, demolish, and reconfigure the interior of the buildings within the Premises to accommodate the operational needs of its business and the businesses of its subtenants. In those circumstances where Lessors approval is required for
interior, non-structural Alterations, Lessor may not withhold such approval solely because the Alteration involves the demolition or removal of improvements without replacements, or results in replacements that have lesser value, quality, or
utility.



(c) All Additional Improvements and Alterations shall
be at Lessees sole cost and expense, and shall be subject to the terms of this Article 11 and of First Class quality. Lessee shall be responsible for any lead or asbestos abatement work necessitated or occasioned by Additional Improvements and
Alterations at the Premises.



(d) All Additional Improvements
and Alterations, whether or not subject to Lessors prior written approval, shall be subject to the provisions of Section 11.6.



21



---

(e) In each instance in this Article 11 in which Lessors prior written approval is required, such
approval shall not be unreasonably withheld, conditioned or delayed. Lessor shall use commercially reasonable efforts to respond to any request for approval within ten (10) business days after receiving Lessees written request for such
approval, along with any required accompanying plans, specifications, data or other information. In the event Lessor fails to respond within such 10-day period, Lessee may deliver to Lessor (by hand delivery only) a written second request for
approval, labeled as such. If Lessor fails to respond to the second request for approval within five (5) business days after receipt, Lessors failure to respond shall be deemed approval of the applicable request for approval. Upon reasonable
advance notice, during Lessors review period, Lessee agrees to meet with Lessors designated representative(s) to review such request for approval.



Section 11.3 Permits and Approvals. Lessee shall be solely responsible for obtaining, at its sole cost and expense, the approval of the City
(and any other governmental agencies with jurisdiction over the Premises) for any general plan amendment, rezoning, variance, conditional use permit, building, electrical and plumbing permits, environmental impact analysis and mitigations imposed
thereby, or other governmental action necessary to permit the development, construction and operation of any Additional Improvements and Alterations in accordance with this Lease. Notwithstanding the foregoing, Lessee shall apply for and prosecute
any required governmental review processes for a general plan amendment, rezoning, variance or use permit only through and in the name of Lessor, or otherwise with the approval of Lessor, and Lessee shall not submit any environmental impact report
or other consultants report containing information regarding Lessor, Lessors lands or Lessors tenants to any public agency without Lessors prior written approval. Lessor, at no cost or expense to itself, shall reasonably
cooperate with Lessee to the extent reasonably required to obtain the approval of the City for any proposed Additional Improvements and Alterations approved by Lessor hereunder. Lessee shall reimburse Lessor for any out-of-pocket expenses reasonably
incurred by Lessor in connection with such cooperation, which reimbursement shall be due and payable by Lessee to Lessor upon demand. Nothing contained herein, however, shall permit or be deemed to permit Lessee to use the Premises for any purpose
not expressly permitted under Section 9.1.



Section 11.4
Design. The following provisions shall apply to all Additional Improvements and Alterations requiring Lessors approval pursuant to Section 11.2(a):



(a) The design of all such Additional Improvements and Alterations, including without limitation, the site plan, structural plans, landscaping plan,
materials, colors, and elevations, shall be subject to Lessors prior written approval.



(b) Prior to submittal to the City, Lessee shall submit to Lessor, for Lessors review, four (4) duplicate sets of design drawings for the proposed Additional Improvements and Alterations, whether or not
they are required by the City to commence the application for governmental design approval. The design drawings shall be subject to Lessors prior written approval. Lessee shall not apply for any governmental approvals until after obtaining
Lessors prior written approval of the design drawings.



22



---

(c) Lessee acknowledges that prior to approving the design drawings for the proposed Additional
Improvements and Alterations, Lessor may be obligated to meet and consult with certain committees and other persons within Lessors organization. Lessee shall provide Lessor with such information and materials as Lessor may request, attend
committee and other meetings with Lessor and other persons associated with Lessor, and take such other actions at Lessees sole cost and expense as Lessor deems reasonably necessary to satisfy the requirements of such committees and other
persons within Lessors organization, and to otherwise respond to Lessees request for approval of the proposed Additional Improvements and Alterations.



(d) Prior to finalizing any construction documents that differ in any material respect from any design or other construction
documents previously approved by Lessor, Lessee shall submit to Lessor for Lessors prior written approval four (4) duplicate sets of such documents, upon which any changes shall be indicated.



(e) If Lessor disapproves any item pursuant to this Article 11, Lessee shall
make whatever changes are reasonably necessary to address the disapproved item and shall resubmit it for Lessors written approval. Lessee shall not proceed with the disapproved item, or any item affected by the disapproved item, until Lessor
has approved Lessees changes. If Lessor and Lessee are unable to agree upon a resolution, Lessor and Lessee shall meet to attempt in good faith to resolve the dispute. Lessor may also, in its sole discretion, present its objections to the
construction of any disapproved items to the City or any other applicable governmental agency with jurisdiction.



(f) Prior to entering into a contract with any design architect, landscape architect or general contractor for any Additional Improvements and Alterations
for which Landlords consent is required, Lessee shall obtain Lessors prior written approval of the identity of each such design architect, landscape architect or general contractor. Each such contract shall contain provisions acceptable
to Lessor that permit the contract to be assumed by Lessor or its designee, at Lessors sole discretion, following a termination of this Lease. Any such assumption shall be on the same terms and conditions (including fees and prices) as set
forth in the contract.



Section 11.5 Prerequisites to
Commencement of Construction. In addition to all other requirements set forth in this Article, before commencing the construction of any Additional Improvements and Alterations which require Lessors approval, and before any building
materials have been delivered to the Premises by Lessee or under Lessees authority, Lessee shall:



(a) Furnish Lessor with a true copy of Lessees contract with the general contractor.



(b) Deliver to Lessor true copies of all documents evidencing the commitment of construction financing for any new

(c) Procure or cause to be procured the insurance coverage described below, and provide Lessor with certified copies of all such insurance or, with the
prior written approval of Lessor, certificates of such insurance in form satisfactory to Lessor. All such insurance shall comply with the requirements of this Article 11 and of Article 19.

Lessee pursuant to Article 19, comprehensive all risk builders risk insurance, including vandalism and malicious mischief, covering all Improvements in place on the Premises, all materials and equipment stored at the Premises and
furnished under contract, and all materials and equipment that are in the process of fabrication at the premises of any third party or that have been placed in due course of transit to the Premises when such fabrication or transit is at the risk of,
or when title to or an insurable interest in such materials or equipment has passed to, Lessee or its construction manager, contractors or subcontractors (excluding any contractors, subcontractors and construction managers tools
and equipment, and property owned by the employees of the construction manager, any contractor or any subcontractor), such insurance to be written on a completed value basis in an amount not less than the full estimated replacement value of the
Additional Improvements and Alterations, as applicable.

owners protective liability, products completed operations for three (3) years after the date of acceptance of the work by Lessee, broad form blanket contractual liability, broad form property damage and full form personal injury (including
but not limited to bodily injury), covering the performance of all work at or from the Premises by Lessee, and in a liability amount not less than the amount at the time carried by prudent owners of comparable construction projects in Santa Clara
County, but in any event not less than Five Million Dollars ($5,000,000) combined single limit, which policy shall contain a cross-liability clause or separation of insureds provision, an endorsement deleting the property damage exclusion as to
explosion, underground, and collapse hazards, and an endorsement providing incidental malpractice coverage, and shall include thereunder for the mutual benefit of Lessor and Lessee, bodily injury liability and property damage liability automobile

Section 11.6 General Construction Requirements.



(a) All construction and other work in connection with any Additional
Improvements and Alterations shall be done at Lessees sole cost and expense and in a prudent and First Class manner and with First Class materials. Lessee shall construct such Additional Improvements and Alterations in strict accordance with
(i) all Applicable Laws, (ii) plans and specifications that are in accordance with the provisions of this Article 11 and all other applicable provisions of this Lease, and (iii) the requirements of the then-current Stanford



24



---

Research Park Handbook promulgated from time-to-time by Lessor (the Handbook); provided that in the event of a direct conflict
between the terms of this Lease and any amendment or modification to the Handbook, the terms of this Lease shall control, unless the applicable amendment or modification reflects any change in Applicable Laws; provided, however, that no amendment to
the Handbook will be binding upon Lessee if it materially and adversely affects the use of the Premises by Lessee, and/or the operation or economic performance of the Premises as an investment property.



(b) Lessee shall give Lessor not less than sixty (60) days notice of any
excavation contemplated on any portion of the Premises. Lessee shall pay Lessors costs and expenses for an on-site Lessor-designated archaeological consultant (which consultant may be an independent contractor or an employee of Lessor) during
any such excavation. When such consultant deems it necessary to investigate the possible presence of, or to protect, archaeological artifacts, such consultant shall have the authority to temporarily halt the excavation work in the area subject to
such investigation. Lessee shall comply, at its own expense, with the consultants requests and state law regarding the protection, removal or reburial of human remains and archaeological artifacts. Any archaeological artifacts discovered on
the Premises shall belong to Lessor. Provided Lessor and its archeological consultant have not been arbitrary in the decision to halt Lessees excavation, Lessor and its archeological consultant shall not be liable for any damages or other
liability that may result from cessation of excavation, or other compliance with the provisions of this Section 11.6.



(c) Lessee shall construct all Additional Improvements and Alterations within setbacks required by Applicable Laws and the Handbook; provided that in the
event of a conflict between or inconsistency with the terms of this Lease and any amendment or modification to the Handbook, the terms of this Lease shall control, unless the applicable amendment or modification reflects any change in Applicable
Laws, or does not materially adversely affect such construction or the cost thereof. Notwithstanding anything contained herein, but subject to Lessors approval rights under Section 11.2(a), Lessee may make repairs, replacements modifications
and additions to any Existing Improvements legally located in any setback areas or other areas of restricted use pursuant to a conditional use permit or similar approval or which otherwise constitute a legal non-conforming use of such restricted
areas; provided, however, that Lessee complies with all Applicable Laws related to the construction or modification of improvements in such restricted areas and obtains and complies with the provisions of all approvals, conditions or consents of the
appropriate federal, state, and local governmental authorities required in connection with the use of such restricted areas and the location and modification of any Existing Improvements therein.



(d) Prior to the commencement of any Additional Improvements and Alterations
costing in excess of Ten Thousand Dollars ($10,000), Lessor shall have the right to post in a conspicuous location on the Premises, as well as to record with Santa Clara County, a Notice of Lessors Nonresponsibility pursuant to the California
Civil Code. Lessee covenants and agrees to give Lessor at least ten (10) days prior written notice of the commencement of any such construction, alteration, addition, improvement, repair or landscaping in order that Lessor shall have sufficient time
to post such notice.



25



---

(e) The provisions of Section 11.4 shall apply to any change in the design elements of the Additional
Improvements and Alterations that are subject to Lessors prior written approval and that have been approved by Lessor, and to any deviations in the actual construction of the Additional Improvements and Alterations from such approved design
elements.



(f) Lessee shall take all customary and necessary
safety precautions during any construction.



(g) Lessee shall
prepare and maintain (i) on a current basis during construction, annotated plans and specifications showing clearly all changes, revisions and substitutions during construction, and (ii) upon completion of construction, as-built drawings showing
clearly all changes, revisions and substitutions during construction, including, without limitation, field changes and the final location of all mechanical equipment, utility lines, ducts, outlets, structural members, walls, partitions and other
significant features of any Additional Improvements and Alterations. These as-built drawings and annotated plans and specifications shall be kept at the Premises or other office of Lessee in the San Francisco Bay Area, and Lessee shall update them

Section 11.8 On Site Inspection. Lessor shall be
entitled to have on site, at all times during the construction of Additional Improvements and Alterations requiring Lessors approval, an inspector or representative who shall be entitled to observe all aspects of the construction. No
inspection performed or not performed by Lessor hereunder shall (a) give, or be deemed to give, Lessor any responsibility or liability for the Additional Improvements and Alterations or the design or construction thereof; (b) constitute, or be
deemed to constitute, approval or acceptance of, any aspect of the design or construction of the Additional Improvements and Alterations; or (c) constitute or be deemed to constitute a waiver of any of Lessees obligations hereunder.

Section 11.11 Remediation Systems. Upon written request, Lessor shall advise Lessee if the
construction or operation of any Additional Improvements and Alterations planned by Lessee is likely to adversely affect any Remediation System. Lessee shall not undertake any Additional Improvements or Alterations likely to have such an adverse

ARTICLE 12.

OWNERSHIP OF IMPROVEMENTS AND ALTERATIONS



All
Improvements shall be the property of Lessee during, and only during, the Term and no longer. During the Term, no Improvements shall be conveyed, transferred or assigned, except as permitted under Articles 22, 23 and 24, and at all such times the
holder of the leasehold interest of Lessee under this Lease shall be the owner of all Improvements. Any attempted conveyance, transfer or assignment of any of the Improvements, whether voluntarily or by operation of law or otherwise, to any person,
corporation or other entity shall be void and of no effect whatever, except as permitted under Articles 22, 23 and 24. Notwithstanding the foregoing, Lessee may from time to time replace the Improvements and any Additional Improvements and
Alterations, provided that the replacements for such items are of equivalent or better value and quality, and such items are free from any liens and encumbrances except for equipment leases and any other financings expressly permitted hereunder; and
provided further and the foregoing requirement that replacements be of equivalent or better value and quality shall not be applicable to interior non-structural Alterations. Upon any termination of this Lease, whether by reason of the expiration of
the Term hereof, or pursuant to any provision hereof, or by reason of any other cause whatsoever, all of Lessees right, title and interest in the Improvements and any Additional Improvements and Alterations shall cease and terminate and title
to the Improvements shall immediately vest in Lessor. Lessee shall surrender the Improvements to Lessor as provided in Article 27. No further deed or other instrument shall be necessary to confirm the vesting in Lessor of title to the Improvements.
However, upon any termination of this Lease, Lessee, upon request of Lessor, shall execute, acknowledge and deliver to Lessor a quitclaim deed confirming that all of Lessees rights, title and interest in the Improvements has expired and that
title thereto has vested in Lessor. Notwithstanding the foregoing, (i) Lessee shall retain ownership of all personal property and trade fixtures used by it in the operation of its business (e.g., furniture, computer systems, movable storage systems,
work stations, and other equipment used in Lessees business), and (ii) the ownership and disposition of all personal property, trade fixtures and improvements installed by any subtenants of the Property shall be as provided in their subleases.
All personal property and trade fixtures of Lessee and its subtenants shall be removed from the Premises at the expiration or earlier termination of this Lease; any such property that remains in the Premises after the expiration or earlier
termination of this Lease shall be deemed abandoned.

any similar law, statute or ordinance now or hereafter in effect.



Section 13.3 Lessees Failure to Repair. If Lessee fails for any reason to repair or maintain the Premises as required by this Lease to Lessors reasonable satisfaction, and does not commence and thereafter continuously and
diligently prosecute to completion the cure of such failure within thirty (30) days after receipt of Lessors written notice, Lessor shall have the right, but not the obligation, to enter onto the Premises and perform such repairs or
maintenance without liability to Lessee (except to the extent of Lessors gross negligence or willful misconduct) for any loss or damage to Lessees furnishings, fixtures, equipment or other personal property or for interference with
Lessees business arising therefrom. If Lessor performs such repairs or maintenance, Lessee shall pay all costs thereof to Lessor upon demand as Additional Rent.

limitation, attorneys fees and costs), suits or other proceedings pertaining thereto.



Section 15.2 Lessors Interests. In no event shall any interest of Lessor in the Premises, including without limitation, Lessors fee interest in the Premises or reversionary interest in the
Improvements or interest under this Lease, be subject or subordinate to any Lien.



Section 15.3 Lessors Right to Cause Release of Liens. If Lessee does not cause any Lien that Lessee does not contest in accordance with Article 16 to be released of record by payment or posting of a
proper bond or insured over within thirty (30) days following the imposition of such Lien, Lessor shall have the right, but not the obligation, to cause the Lien to be released by any means Lessor may deem appropriate, and the amount paid by Lessor,
together with all expenses Lessor incurs in connection therewith (including, without limitation, reasonable attorneys fees and expenses), plus interest at the Interest Rate from the date of payment by Lessor, shall be Additional Rent,
immediately due and payable by Lessee to Lessor upon demand.



Section 15.4 Liens Relating to Pre-Existing Environmental Condition and other Lessor Liens. Lessor covenants and agrees to keep the Land and the Premises and every part thereof free and clear of and from any and all Liens for: (a)
work or labor done, services performed, materials, appliances, or power contributed, used or furnished, or to be used, for or in connection with the Pre-Existing Environmental Condition (except to the extent the foregoing is undertaken by third
parties pursuant to access agreements related to the remediation of the Pre-Existing Environmental Condition, which is referred to herein as Third Party Remediation Work), or (b) any work to be conducted at the sole cost of
the Lessor on or about the Premises, any work or construction conducted by or at the request of Lessor, or to be conducted under the terms of this Lease at the Lessors sole cost, on or about the Premises (collectively, Lessor
Liens. Lessor shall promptly and fully pay and discharge any and all claims upon which any such Lessors Lien may or could be based, and keep the Premises free and clear of, and save and hold Lessee and the Premises harmless from,
any and all such Lessors Liens and claims of Lessors Liens and any damages, liabilities, costs (including, without limitation, attorneys fees and costs), suits or other proceedings pertaining thereto. With respect to Third Party
Remediation Work, Lessor shall, for the benefit of Lessee and to the extent necessary to protect Lessees interest in the Premises, enforce in a commercially reasonable manner all rights it has pursuant to any access agreement or other
agreement it may have with the party performing or responsible for the performance of such Third Party Remediation Work with respect to payment, removal of liens, insurance protection, obligations to refrain from interfering with other uses on the
Premises, indemnification, and similar protections to the extent they exist in such agreements, all at Lessors sole cost. If any Lien encumbers Lessees interest in the Premises as a result of such Third Party Remediation Work, Lessor
shall use reasonable efforts to cause such Lien to be removed and, if such reasonable efforts are unsuccessful, Lessor shall cause such Lien to be removed so that it no longer affects Lessees interest in the Premises and this Lease, and Lessor
shall indemnify Lessee from all damages, liabilities, costs (including attorneys fees) related to such Lien.

Lessee and Lessor shall have the right to contest, in good faith, the amount or validity of any Lien and Lessors Lien, respectively, provided that, before doing so, it shall give the other written notice of its intention to do
so within thirty (30) days after the recording of such Lien and provided further that it shall, at its expense, defend itself and the other against such Lien and shall pay and satisfy any adverse judgment that may be rendered concerning such Lien
before that judgment is enforced against the Premises. In addition, at the request of the other party, the contesting party shall procure and record the bond provided for in Section 3143 of the California Civil Code, or in any comparable statute
hereafter enacted providing for a bond freeing the Premises from the effect of such Lien, or, at the contesting partys election, shall cause such Lien to be insured over for the benefit of the other party. The contesting party shall pay all

INSURANCE REQUIREMENTS



Section 17.1 Compliance with
Applicable Laws. Subject to the provisions of Article 18, Lessee, at Lessees sole cost and expense, shall comply with all Applicable Laws relating to this Lease, the Premises and the Improvements during the Term. Lessee shall give Lessor
prompt written notice of any violation of Applicable Laws known to Lessee and, at its sole cost and expense, Lessee shall promptly rectify any such violation. Without in any way limiting the generality of the foregoing obligation of Lessee, Lessee
shall be solely responsible for compliance with, and shall make or cause to be made all such improvements and alterations to the Premises (including, without limitation, removing barriers and providing alternative services) as shall be required by
the Americans with Disabilities Act (42 USC section 12101 et seq.), as the same may be amended from time to time, and any similar or successor laws, and with any rules or regulations promulgated thereunder. Any work or installations made or
performed by or on behalf of Lessee or any person or entity claiming through or under Lessee in order to conform the Premises to Applicable Laws shall be subject to and performed in compliance with the provisions of Article 11.

refusal by insurance companies of good standing to insure the Premises or any such property in amounts required hereunder. Lessee, at Lessees expense, shall comply with all rules, orders, regulations or requirements of the American Insurance

Property to do any act, that materially increases the dangers to human health or the environment, poses an unreasonable risk of harm to any person (whether on or off the Premises), is contrary to any reasonable requirement of any insurer,
constitutes a public or private nuisance, constitutes waste, or violates any covenant, condition, agreement or easement applicable to the Premises.



ARTICLE 18.

ENVIRONMENTAL ISSUES



Section 18.1 Hazardous Substances. No Hazardous
Substance shall be used, treated, kept, stored, transported, handled, sold or Released at, on, under or from the Premises during the Term. Notwithstanding the foregoing, Lessee and Lessees Agents and subtenants may use reasonable quantities of
Hazardous Substances as are normally used in and reasonably required for research and development (as defined in Section 9.1), and/or as are present in standard janitorial and office products, and then only in strict compliance with all
Environmental Requirements. As of the Commencement Date, Lessee shall provide Lessor a complete list of all Hazardous Substances (excluding standard janitorial and office products) used or stored by Lessee or any Lessee Agents at the Premises.
Throughout the Term, Lessee shall continue to update this list so that it remains current. Without limiting the foregoing, Lessee shall, at its own expense, procure, maintain in effect and comply with all conditions of any and all permits, license
and other governmental and regulatory approvals required for Lessees use of Hazardous Substances at the Premises, including, without limitation, discharge of appropriately treated Hazardous Substances into or through any sanitary sewer serving
the Premises.

shall use best efforts not to interfere with the access rights of any third parties undertaking Remediation Activities pursuant to the access agreements identified in Schedule 18.2 and to any additional access agreements entered into pursuant
to Section 3.2 (collectively, the Access Agreements), it being the intent of the parties that Lessees leasehold interest is subject to all such Access Agreements. During the Term, Lessor shall diligently enforce all
of the obligations of third parties under the Access Agreements so that Lessee shall receive the full benefit thereof. To the extent Lessor enters into any additional access agreements during the Term, Lessor shall use best efforts to ensure that
any third parties who are granted access rights will not unreasonably interfere with Lessees operations in the exercise of such access rights, and Lessee shall cooperate with Lessor and third parties who have rights pursuant to such access
agreements to permit such parties to conduct all activities reasonably necessary and permitted by such access agreements to investigate and remediate the Pre-Existing Environmental Condition; provided, however, that in doing so, Lessor and such
third parties shall be subject to Section 3.2(d), and shall use commercially reasonable efforts to minimize any interference with Lessees use of the Premises, and shall not materially adversely affect any Improvements on, or the use, operation
or value of the Premises.



Section 18.3 Lessees
Indemnity for Environmental Claims. In addition to the indemnity obligations assumed by Lessee pursuant to Section 20.1, Lessee shall indemnify, protect, defend, reimburse, and save and hold harmless Lessor and Lessors trustees, officers,
directors and employees from and against any and all Environmental Claims to the extent caused

by (a) Lessee Environmental Activity, (b) any non- compliance by Lessee or its Agents, subtenants or invitees with Environmental Requirements at the Premises
(other than those from which Lessee is expressly released pursuant to Section 18.11), (c) any other acts or omissions of Lessee or Lessees Agents, subtenants or invitees in or about the Premises which results in the Release of Hazardous
Substances (other than the Hazardous Substances constituting or arising as a consequence or the Pre-Existing Environmental Condition) or damage to the Remediation Systems, or (d) any Exacerbation by Lessee or Lessees Agents, subtenants or
invitees of the Pre-Existing Environmental Condition (Lessees Environmental Indemnity Obligations). Lessees obligations hereunder shall include, but not be limited to, the burden and expense of defending all
claims, suits and administrative proceedings (with counsel reasonably approved by Lessor), even if such claims, suits or proceedings are groundless, false or fraudulent; conducting all negotiations of any description; and promptly paying and
discharging when due any and all judgments, penalties, fines or other sums due against or from Lessor or the Premises. Prior to retaining counsel to defend such claims, suits or proceedings, Lessee shall obtain Lessors written approval of the
identity of such counsel, which approval shall not be unreasonably withheld, conditioned or delayed. Notwithstanding anything to the contrary herein, Lessees Environmental Indemnity Obligations shall not include any of the following: (i) any
Environmental Claims to the extent such Environmental Claims are proximately caused by a breach of any provision of this Lease by Lessor or Lessors Agents; (ii) any Environmental Claims arising out of the Pre-Existing Environmental Condition
(except to the extent covered pursuant to clause (d) above); or (iii) the amount of any settlement not approved in writing by Lessee, which approval shall not be unreasonably withheld.



Section 18.4 Indemnity for Lessee Claims. Notwithstanding any provisions of this Lease set forth in Sections other
than this Section 18.4, Lessor shall indemnify, protect, defend, reimburse, and save and hold harmless the Lessee herein named, TIBCO Software, Inc., each permitted assignee of Lessees interest in this Lease, any permitted sublessee of the
entire Premises, and their respective officers, directors, shareholders, and lenders (collectively, Lessee Indemnitees) from and against any and all Environmental Claims (other than those set forth in subpart (e) of the
definition of Environmental Claims and as otherwise limited in this Section 18.4) incurred by a Lessee Indemnitee or threatened, made, brought, or entered against any Lessee Indemnitee by any federal, state or local environmental governmental
agency, or by any other person, or class of persons, including, without limitation, those for bodily injury, damage to real or personal property, or costs of response as defined by Section 101(25) of CERCLA, 42 U.S.C. 9601(25) (collectively
Lessee Claims) to the extent such Lessee Claims arise out of or result from: (a) the Pre-Existing Environmental Condition, including without limitation subsequent migration of the Pre-Existing Environmental Condition from
the Premises during the Term; (b) any violation by Lessor of any Environmental Requirements; (c) acts of any third party present on the Premises pursuant to any agreement entered into by Lessor or any predecessor in interest permitting such party
access to the Premises for purposes of a Remediation Activity or any of the Access Agreements, and/or (d) any Remediation Activity conducted, or required by any Environmental Requirement to be conducted, on the Premises with respect to the
Pre-Existing Environmental Condition (collectively, Lessors Environmental Indemnity Obligations). Lessors obligations hereunder shall include, but not be limited to, the burden and expense of defending all
claims, suits and administrative



32



---

proceedings (with counsel reasonably approved by Lessee), even if such claims, suits or proceedings are groundless, false or fraudulent; conducting all
negotiations of any description; and promptly paying and discharging when due any and all judgments, penalties, fines or other sums due against or from Lessee or the Premises. Prior to retaining counsel to defend such claims, suits or proceedings,
Lessor shall obtain Lessees written approval of the identity of such counsel, which approval shall not be unreasonably withheld, conditioned or delayed. If so requested in writing at the time that Lessor consents to a proposed Transfer of
Lessees interest in this Lease pursuant to Article 22, Lessor shall confirm that Lessors Environmental Indemnity Obligations will operate in favor of the proposed transferee. Notwithstanding anything to the contrary herein, Lessors
Environmental Indemnity Obligations shall not include any of the following: (i) any Lessee Claims to the extent such Lessee Claims arise out of or are proximately caused by a breach of any provision of this Lease by Lessee or another Lessee
Indemnitee; (ii) any Lessee Claims to the extent such Lessee Claims arise out of any Lessee Environmental Activity, any Exacerbation of the Pre- Existing Environmental Condition by Lessee or Lessees Agents, subtenants or invitees, or any
interference with or damage to Remediation Systems cause by Lessee or Lessees Agents, subtenants or invitees; (iii) any Lessee Claims brought by any employee of Lessee or any Lessee Indemnitee to the extent such Lessee Claim is covered by
workers compensation insurance maintained by Lessee or such Lessee Indemnitee; provided that nothing herein shall release Lessor from liability for any such claim to the extent that an independent basis (other than pursuant to any
workers compensation laws) for any such liability of the Lessee Indemnitee exists; (iv) any Lessee Claims for lost profits or lost revenues of any type or kind resulting from loss of use or occupancy of the Premises or any part thereof by
Lessee or any Lessee Indemnitee, or injury to or inconvenience or interference with Lessees business resulting from the Remediation Activities, the Remediation Systems or the Pre-Existing Environmental Condition; provided that Lessee shall be
entitled to an abatement of Base Rent otherwise due hereunder to the extent that the Premises are rendered unusable as a result of the presence of any condition which would be the subject of Lessors Environmental Indemnity Obligations but for
this subsection (iv); or (v) the amount of any settlement not approved in writing by Lessor, which approval shall not be unreasonably withheld. In no event shall Lessors Environmental Indemnity Obligations include remediation to standards more
stringent than those required by the appropriate governmental agencies in order to comply with Environmental Requirements, but Lessor shall remediate at least to a standard which permits Lessee to make the same use of the Premises as it did prior to
the date the Premises were rendered unusable as a result of the presence of any condition which triggered the Lessors Environmental Indemnity Obligation. The benefit of the foregoing indemnity shall not be assignable to any subtenant or
licensee of Lessee; provided, however, that notwithstanding the foregoing, (i) the benefit of the foregoing indemnity may be assignable to a permitted subtenant of Lessee who subleases all of the Improvements; and (ii) Lessee may enforce such
indemnity for the benefit of any subtenant or licensee of Lessee, and in this regard, Lessee may provide indemnification protection to such subtenants or licensees to the extent of the indemnity provided to it by Lessor and enforce its rights under
Lessors indemnity so as to enable Lessee to provide the benefit of such indemnity to such subtenants or licensees, but all so long as only Lessee, and not such subtenants or licensees, is the party entitled to bring the action seeking
enforcement of Lessors indemnity against Lessor.

Section 18.5 Obligation to Remediate. Notwithstanding the obligation of Lessee to indemnify Lessor
pursuant to this Lease, Lessee shall, upon demand of Lessor, and at Lessees sole cost and expense, promptly take all Remediation Activity necessary to remediate the Premises from the effects of any Lessee Environmental Activity. Lessee shall
undertake all Remediation Activities necessary to remediate the Premises from the effects of such Lessee Environmental Activity to a condition allowing the same unrestricted use of the Premises as permitted immediately prior to occurrence of such
Lessee Environmental Activity, notwithstanding any lesser standard of remediation allowable under Applicable Laws. All such work shall be performed by one or more contractors selected by Lessee and reasonably approved in advance and in writing by
Lessor, which approval shall not be unreasonably withheld or delayed. Lessee shall proceed continuously and diligently with such Remediation Activities, provided that in all cases such actions shall be in accordance with all Applicable Laws. Any
such actions shall be performed in a good, safe and workmanlike manner. Lessee shall pay all costs in connection with such investigatory and remedial activities, including but not limited to all power and utility costs, and any and all taxes or fees
that may be applicable to such activities. Lessee shall promptly provide to Lessor copies of testing results and reports that are generated in connection with the above activities and any that are submitted to any governmental entity. Promptly upon
completion of such Remediation Activities, Lessee shall permanently seal or cap all monitoring wells and test holes in accordance with sound engineering practice and in compliance with Applicable Laws, remove all associated equipment, and restore
the Premises to the maximum extent possible, which shall include, without limitation, the repair of any surface damage, including paving, caused by such Remediation Activities. Lessee shall not be in default of its obligations under this Section
18.5 if it is contesting in good faith its obligation to conduct the relevant Remediation Activity or if it is seeking to cause a third party, who is also liable for the Remediation Activities, to conduct such activities, so long as there is no
material adverse effect on Lessor during such contest or attempt to cause a third party to perform.



Section 18.6 Obligation to Notify. If Lessee or Lessor shall become aware of or receive notice or other communication in writing concerning any
actual, alleged, suspected or threatened violation of Environmental Requirements, or liability for Environmental Claims in connection with the Premises, or with respect to the Pre- Existing Environmental condition, including but not limited to,
notice or other communication concerning any actual or threatened investigation, inquiry, lawsuit, claims, citation, directive, summons, proceeding, complaint, notice, order, writ, or injunction, relating to same, then such party promptly shall
deliver to the other party a written description of said notice or other communication, and documentation of any corrective action or mitigation measures undertaken or requested by such party.



Section 18.7 Periodic Audits. Lessee shall establish and maintain, at
its sole cost and expense, a system to assure and monitor continued compliance on the Premises with Environmental Requirements related to Lessee Environmental Activity. No more than once per Lease Year, or at any time Lessor has a reasonable basis
for belief that Lessee is in breach of its obligations under this Article 18, Lessor may retain a consultant selected by Lessor to undertake a detailed review of such compliance (the Environmental Audit). A copy of the
Environmental Audit report shall be promptly supplied to Lessor and Lessee when it becomes available. In the event the Environmental Audit identifies any deficiencies in the compliance of the Premises with Environmental Requirements due to any
Lessee Environmental Activity,



34



---

Lessee shall promptly correct any such deficiencies identified in the Environmental Audit, and document to Lessor that corrective action has been taken. In
such event, Lessee shall also reimburse Lessor for the cost of the Environmental Audit. If the Environmental Audit identifies any such deficiency in compliance of the Premises with Environmental Requirements due to any Lessee Environmental Activity,
then, within nine (9) months of the date of the Environmental Audit, Lessor may request a detailed review of the status of such violation by a consultant selected by Lessor (the Supplemental Audit). Lessee shall pay for the
cost of any Supplemental Audit. A copy of the Supplemental Audit shall be promptly supplied to Lessor and Lessee when it becomes available.



Section 18.8 Right to Inspect. In addition to Lessors rights under Section 18.7 above, Lessor shall have the right to enter and conduct an
inspection of the Premises, including invasive tests, at any reasonable time and upon reasonable advance notice, to determine whether Lessee is complying with the terms of this Lease, including but not limited to the compliance of the Premises and
the activities thereon with Environmental Requirements and the existence of Environmental Claims as a result of the condition of the Premises or surrounding properties and activities thereon. Lessor shall have the right, but not the obligation, to
retain at its expense any independent professional consultant to enter the Premises to conduct such an inspection, and to review any report prepared by or for Lessee concerning such compliance. Lessee hereby grants to Lessor and Lessors Agents
the right to enter the Premises and to perform such tests on the Premises as are reasonably necessary to conduct such review and inspections. Except to the extent of Lessors breach of this Lease or gross negligence or willful misconduct in the
exercise of its rights under this Section, Lessee hereby waives and releases any claims for damages for any injury or inconvenience to or interference with Lessees business at the Premises, any loss of occupancy or quiet enjoyment or the
Premises or any other loss, damage, liability or cost occasioned by Lessors exercise of the rights reserved to Lessor under, or granted to Lessor pursuant to this Section. In no event shall Lessee be entitled to terminate this Lease as a
result of Lessors exercise of such rights, notwithstanding any possible liability of Lessor for damages as a result of its gross negligence or willful misconduct.



Section 18.9 Right to Remediate. Should Lessee fail to perform or observe any of its obligations or agreements
pertaining to Hazardous Substances or Environmental Requirements and fail to commence to cure such non-compliance within thirty (30) days after written notice or thereafter to diligently complete such cure, then Lessor shall have the right, but not
the obligation, without limitation of any other rights of Lessor hereunder, to enter the Premises personally or through Lessors Agents and perform the same. Lessee agrees to indemnify Lessor for the costs thereof and liabilities therefrom as
set forth above in this Article 18.



Section 18.10 Release
of Lessor. Lessee represents and acknowledges that it is aware that, prior to the Commencement Date, detectable amounts of Hazardous Substances and byproducts thereof may have been Released to soil and groundwater beneath and/or in the vicinity
of the Premises as described in the documents listed on the attached Schedule 18.10. These Hazardous Substances and by-products thereof and all other Hazardous Substances present on, in or under the Land as of the Commencement Date, or which
are in soil and/or ground water of other property as of the Commencement Date and thereafter migrate to the Land are hereinafter collectively referred to as the Pre-Existing Environmental Condition. Lessee



35



---

further represents and acknowledges that it has made such investigations and inquiries as it deems appropriate to ascertain the effects, if any, of the
Pre-Existing Environmental Condition on the Premises and on persons using the Premises. Except as set forth in the Agreement to Lease or as otherwise specifically provided in this Lease, Lessor makes no representation or warranty with regard to the
Pre-Existing Environmental Condition or with regard to any aspect of the environmental condition of the Premises. Lessee, on behalf of itself, Lessees Agents, and Lessees successors and assigns, hereby releases Lessor and the Lessor
Released Parties (as defined in Section 18.10(b)) from any and all Environmental Claims of whatever kind or nature, whether known or unknown or suspected or unsuspected which Lessee may have, claim to have, or which may hereafter accrue, arising out
of or relating to or in any way connected with the Pre-Existing Environmental Condition or the presence, suspected presence, Release or suspected Release of any Hazardous Substances in or into the air, soil, groundwater, surface water or
improvements at, on, about, under or within the Premises or any portion thereof, or elsewhere in connection with the transportation of Hazardous Substances to or from the Premises, in each case prior to the Commencement Date. In connection with such
release, Lessee hereby waives any and all rights conferred upon it by the provisions of Section 1542 of the California Civil Code, which reads as follows:



A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which
if known by him must have materially affected his settlement with the debtor.



or by the provisions of any similar statute.



Notwithstanding the foregoing, Lessees release of Lessor shall not extend to: (a) any Lessee Claims arising out of Lessors Environmental Indemnity Obligations, or (b) any possible claim Lessee may have against Lessor as a matter
of law by reason of Lessors ownership of the Premises or any other property which results in (i) the migration onto the Premises of Hazardous Substances Released from any other property as a result of Lessors activities on such other
property, or (ii) Hazardous Substances coming onto, in, or under the Premises after the Commencement Date that Lessee proves did not result from (A) any Lessee Environmental Activity, (B) any Exacerbation of the Pre-Existing Environmental Condition
by Lessee or Lessees Agents, or (C) any negligence of Lessee or any of Lessees Agents (provided that Lessor shall not be deemed to have waived any rights under any common law or statutory provisions with respect to any such Hazardous
Substances).



Section 18.11 Release of Lessee. Lessor on
behalf of itself and the Lessor Related Parties hereby releases Lessee, its subtenants, successors and assigns, and their respective officers, directors, agents and employees, from any and all Environmental Claims of whatever kind or nature, whether
known or unknown or suspected or unsuspected which Lessor may have, claim to have, or which may hereafter accrue against Lessee or the other released parties, arising out of or relating to or in any way connected with the Pre-Existing Environmental
Condition (except to the extent of any Exacerbation thereof). In connection with such release, Lessor hereby waives any and all rights conferred upon it by the provisions of Section 1542 of the California Civil Code, which reads as follows:



36



---

A general release does not extend to claims which the creditor does not know or suspect to exist in his
favor at the time of executing the release, which if known by him must have materially affected his settlement with the debtor.



or by the provisions of any similar statute.



Nothing in the foregoing shall be deemed to release Lessee from any obligations or indemnities it has expressly agreed to or assumed under this Lease or
under the Agreement to Lease.



Section 18.12 Limitation on
Lessees Liability. Except as provided in this Article 18 with respect to Exacerbation, or as otherwise specifically set forth in any other provisions of this Lease, Lessee shall have no obligation to repair or restore any damage to the
Premises, to comply with any Environmental Requirements, or to indemnify Lessor from any Environmental Claims to the extent any of the foregoing arise out of or in connection with (a) the Pre-Existing Environmental Condition, (b) any Third Party
Remediation Work, or (c) any act or omission of any third party present on the Premises pursuant to any Access Agreement.



Section 18.13 General Provisions.



(a) The obligations of Lessee under this Article 18 shall not be affected by any investigation by or on behalf of Lessor, or by any information which
Lessor may have or obtain as a result of any such investigation.



(b) As used in this Article 18 and in Article 20, the term Lessor Released Parties shall include The Board of Trustees of The Leland Stanford Junior University, and all of its affiliated organizations, and their
respective trustees, directors and officers.



(c) The
provisions of this Article 18 shall survive any termination of this Lease.



(d) The provisions of Article 19 (Insurance) shall not limit in any way Lessees obligations under this Article 18.



(e) Nothing in the foregoing shall be deemed to release Lessee from any obligations or indemnities it has expressly agreed to or assumed under this Lease
or under the Agreement to Lease. The parties hereby reserve any common law or statutory rights each may have against the other with respect to violations of Environmental Requirements occurring on the Premises that are neither the result of
Lessees Environmental Activities, Exacerbation, nor the Pre-Existing Environmental Condition.



ARTICLE 19.

INSURANCE



Section 19.1 Required Insurance. At all times during the Term and at
its sole cost and expense, Lessee shall obtain and keep in force for the benefit of Lessee and Lessor the following insurance:



37



---

(a) Property Insurance. Special perils, fire, and other perils normally included within extended
coverage insurance on all Improvements, and also earthquake insurance as long as such earthquake insurance is available at commercially reasonable rates and is then customarily carried with respect to comparable buildings in the Stanford Research
Park. The amount of such insurance shall be the Full Insurable Replacement Value; provided that earthquake insurance shall be in an amount that is commercially available and comparable to that which would be customarily carried by owners of
comparable properties in the Palo Alto area. Each such policy shall specify that proceeds shall be payable whether or not any improvements are actually rebuilt. Each such policy shall include an endorsement protecting the named and additional
insureds against becoming a co-insured under the policy.



Full Insurable Replacement Value means 100% of the actual costs to replace the Improvements (without deduction for depreciation but with standard exclusions such as foundations, excavations, paving and landscaping,
as applicable to specific perils), including the costs of demolition and debris removal and including materials and equipment not in place but in transit to or delivered to the Premises. Lessee shall maintain coverage at the current Full Insurable
Replacement Value throughout the Term.



(b) Rental and
Business Interruption Insurance. Insurance against loss of rental from the Premises, under a rental value insurance policy, or against loss from business interruption under a business interruption policy, covering risk of loss due to causes
insured against under subsection (a), in an amount not less than twelve (12) months of the Base Rent then due under this Lease, but if Base Rent has been prepaid for the period in question, then only to the extent of the Base Rent that is actually
due (taking into account any such prepayment) for the period in question.



(c) Workers Compensation and Employers Liability Insurance. Workers Compensation Insurance in the amounts and coverages required under workers compensation, disability and similar
employee benefit laws applicable to the Premises, and Employers Liability Insurance with limits not less than $1,000,000 or such higher amounts as may be required by law.



(d) Comprehensive General Liability Insurance. Comprehensive general liability insurance through one or more primary
and umbrella liability policies against claims, including but not limited to, bodily injury and property damage occurring on the Premises, with such limits as may be reasonably required by Lessor from time to time, but in any event not less than
$3,000,000, combined single limit and annual aggregate for the Premises, which Lessee shall increase as necessary during the Term to maintain adequate coverage over time that is comparable to the requirements in effect as of the execution of this
Lease. Such insurance shall insure the performance by Lessee of the indemnity agreements contained in this Lease. If any governmental agency or department requires insurance or bonds with respect to any proposed or actual use, storage, treatment or
disposal of Hazardous Substances by Lessee or any sublessee, tenant, or licensee of Lessee, Lessee shall be responsible for such insurance and bonds and shall pay all premiums and charges connected therewith; provided, however, that this provision
shall not and shall not be deemed to modify the provisions of this Article 19.



38



---

Such insurance shall (i) include employees as additional insureds; (ii) provide blanket contractual
coverage; (iii) provide Products and Completed Operations and Independent Contractors coverage and Broad Form Property Damage liability coverage without exclusions for collapse, explosion, demolition, underground coverage and excavating, including
blasting; (iv) provide automobile liability coverage for owned, non- owned and hired vehicles; (v) provide liability coverage on all mobile equipment used by Lessee; and (vi) include a cross liability endorsement (or provision) permitting recovery
with respect to claims of one insured against another. Such insurance shall insure against claims for bodily injury, including death resulting therefrom, and damage to or destruction of property and arising from Lessees operations hereunder
and whether such operations are performed by Lessee or any of its contractors, subcontractors, or by any other person.



(e) Other. All other insurance that Lessee is required to maintain under Applicable Laws.



Section 19.2 Policy Form and General.



(a) All of the insurance policies required under this Lease, including
without limitation, under the provisions of Article 11 and this Article 19, and all renewals thereof shall be issued by one or more companies of recognized responsibility, authorized to do business in California with a financial rating of at least a
Class B+ (or its equivalent successor) status, as rated in the most recent edition throughout the Term of Bests Insurance Reports (or its successor, or, if there is no equivalent successor rating, otherwise reasonably acceptable to Lessor).
The proceeds of all property damage and builders risk policies of insurance shall be payable, for application in accordance with this Lease, to either Lessor or, if Lessee shall so request in writing, to a trust company approved by Lessor and
Lessee (which approval shall not be unreasonably withheld), which trust company shall hold such insurance proceeds for the benefit of Lessor and Lessee and shall, pursuant to joint instructions approved by Lessor and Lessee, disburse such funds in
accordance with the provisions of Article 21. The property and liability insurance hereunder shall name as additional insureds Lessor and such other parties as Lessor reasonably may request. All deductibles and self-insurance retention shall be paid
by Lessee. All insurance of Lessee shall be primary coverage.



(b) Each policy of property insurance and all other policies of insurance on the Improvements and/or the Premises which shall be obtained by Lessee, whether required by the provisions of this Lease or not, shall be made expressly subject to
the provisions of this Article 19. Lessee shall use commercially reasonable efforts to cause each required policy to provide that no cancellation, termination or material reduction in coverage shall occur without thirty (30) days prior written
notice to Lessor. Each policy, or a certificate of the policy executed by the insurance company evidencing that the required insurance coverage is in full force and effect, shall be deposited with Lessor on or before the date of this Lease, shall be
maintained throughout the Term, and shall be renewed not less than thirty (30) days before the expiration of the term of the policy. No policy shall contain any exclusion that conflicts with or impairs the coverage required by this Article 19.



39



---

(c) If either party shall at any time deem the limits of any of the insurance described in this Lease
then carried or required to be carried to be either excessive or insufficient, the parties shall endeavor to agree upon the proper and reasonable limits for such insurance then to be carried and such insurance shall thereafter be carried with the
limits thus agreed upon until further change pursuant to the provisions of this subsection. If the parties shall be unable to agree on the proper and reasonable limits for such insurance, then such limits shall be determined pursuant to the
provisions of Article 36. The decision of the arbitrator as to such limits for such insurance then to be carried shall be binding upon the parties and such insurance shall be carried with the limits as thus determined until such limits shall again
be changed pursuant to the provisions of this subsection. The expenses of such determination shall be borne equally between Lessor and Lessee.



(d) No approval by Lessor of any insurer, or the terms or conditions of any policy, or any coverage or amount of insurance, or any deductible amount shall
be construed as a representation by Lessor of the solvency of the insurer or the sufficiency of any policy or any coverage or amount of insurance or deductible, and Lessee assumes full risk and responsibility for any inadequacy of insurance coverage
or any failure of insurers.



(e) Should Lessee fail to take out
and keep in force each insurance policy required under this Article 19, or should such insurance not be reasonably approved by Lessor and should Lessee not rectify the situation within five (5) business days after written notice from Lessor to
Lessee, Lessor shall have the right, without assuming any obligation in connection therewith, to purchase such insurance at the sole cost of Lessee, and all costs incurred by Lessor shall be payable to Lessor by Lessee within thirty (30) days after
demand as Additional Rent and without prejudice to any other rights and remedies of Lessor under this Lease.



(f) Notwithstanding anything to the contrary contained herein, to the extent permitted by their respective policies of insurance and to the extent of
insurance proceeds received (or which would have been received had the party carried the insurance required by this Lease) with respect to the loss, Lessor and Lessee each hereby waive any right of recovery against the other party and against any
other party maintaining a policy of insurance with respect to the Premises or the Improvements or any portion thereof for any loss or damage sustained by such other party with respect to the Premises or the Improvements, or any portion thereof, or
the contents of the same or any operation therein, whether or not such loss is caused by the fault or negligence of such other party. Either party shall notify the other party if the policy of insurance carried by it does not permit the foregoing
waiver.



ARTICLE 20.

INDEMNITY AND RELEASE



Section 20.1 Indemnity. Lessee shall indemnify, protect, defend and save and hold harmless the Lessor Released Parties from and against, and shall
reimburse the Lessor Released Parties for, any and all claims, demands, losses, damages, costs, liabilities, causes of action and expenses, including, without limitation, reasonable attorneys fees and expenses, incurred in any way in
connection with or arising from, in whole or in part, the following: (a) this Lease; (b) any default by Lessee in the observance or performance of any of the terms, covenants or conditions



40



---

of this Lease on Lessees part to be observed or performed; (c) the use, occupancy or manner of use or occupancy of the Premises by Lessee or any
sublessee, licensee, or any other person or entity claiming by, through or under Lessee; (d) the conduct or management of any work or thing done in or on the Premises by Lessee or any sublessee, licensee or any other person or entity claiming by,
through or under Lessee; (e) the design, construction, maintenance, or condition of any Improvements during the Term; (f) the condition of the Premises during the Term; (9) any actual or alleged acts, omissions, or negligence of Lessee or
Lessees Agents, subtenants or invitees, in, on or about the Premises or any other of Lessors lands; and (h) any accident or other occurrence on the Premises from any cause whatsoever during the Term. In case any claim, action or
proceeding be brought, made or initiated against a Lessor Released Party relating to any of the above described events, acts, omissions, occurrences, or conditions, Lessee, upon notice from such Lessor Released Party, shall at its sole cost and
expense, resist or defend such claim, action or proceeding with attorneys reasonably approved by such Lessor Released Party. Notwithstanding the foregoing, Lessees obligations under this Section shall not apply to the extent (i) Lessor has
expressly released Lessee from liability under the terms of this Lease, (ii) of Lessors breach of its obligations under this Lease, or (iii) of the gross negligence or willful misconduct of Lessor or Lessors Agents. Notwithstanding
anything contained in this Section 20.1, the provisions of this Section 20.1 shall not apply to the following subjects, which shall be governed exclusively by the sections of this Lease mentioned: (i) matters concerning the Pre-Existing
Environmental Condition, Environmental Claims and Hazardous Substances, which are governed by Article 18; (ii) any Appropriation or any loss or damage by fire or other cause resulting in either partial or total destruction of the Premises, which is
governed by Article 21; and (iii) Lessees liability for damages for breach of lease, which is governed by Article 25.



Section 20.2 Limitation on Lessors Liability. Except as otherwise provided in this Lease, or otherwise arising from Lessors breach of
its obligations under this Lease or the gross negligence or willful misconduct of Lessor or Lessors Agents, Lessor shall not be responsible for, and Lessee hereby waives any and all claims and causes of action whatsoever of any kind or nature
against Lessor and Lessors Agents for, any injury, loss, damage or liability to any person or property in or about the Premises or in any way connected with the Premises or this Lease, from any cause whatsoever.



ARTICLE 21.

APPROPRIATION, DAMAGE OR DESTRUCTION



Section 21.1 No Termination, No Affect on Rental Obligation. No Appropriation nor any loss or damage by fire or other cause resulting in either
partial or total destruction of the Premises, the Improvements or any other property on the Premises shall, except as otherwise provided herein, operate to terminate this Lease. Except as expressly provided herein, no such Appropriation, loss or
damage shall affect or relieve Lessee from Lessees obligation to pay Rent, and in no event shall Lessee be entitled to any proration or refund of Rent paid hereunder. Unless this Lease is terminated pursuant to and in accordance with this
Article 21, and except as expressly provided in Section 21.3 below with respect to reduction of Rent in the event of a partial Appropriation, no such Appropriation, loss or damage shall relieve or discharge Lessee from the payment of Rent, or from
the performance and observance of any of the agreements, covenants and conditions herein contained on the part of Lessee to be performed and observed.



41



---

Lessee hereby expressly waives the provisions of Sections 1932(2) and 1933(4) of the California Civil Code, or any amendments thereto or any similar law,
statute or ordinance now or hereafter in effect.



Section
21.2 Evaluation of Effect of Damage or Appropriation. Upon the occurrence of any event of damage or destruction to the Premises or the Improvements or any portion thereof, Lessee shall promptly undertake to determine the extent of the same and
the estimated cost and time to repair and restore the Improvements in accordance with the provisions of this Lease. Lessee shall notify Lessor of its estimation of such cost and time not later than sixty (60) days after the occurrence of the damage
or destruction. Upon any Appropriation of less than the entire Premises, Lessee shall promptly undertake to determine the effect of such Appropriation on the remaining portion of the Premises and the function of the Premises and, if this Lease is
not terminated pursuant to and in accordance with this Article 21, the cost and time to make any repairs and Alterations to the remaining portion of the Premises necessary in order for the Premises to be restored to an economically viable whole
capable of operation in accordance with this Lease. Lessee shall notify Lessor of its estimation of such cost and time not later than sixty (60) days after the occurrence of the Appropriation.



Section 21.3 Partial Appropriation; Amendment; Duty to Restore. If
less than the entire Premises is subject to an Appropriation and this Lease is not terminated by either party pursuant to and in accordance with this Article 21, this Lease shall be deemed terminated as to the part so Appropriated as of the date of
Appropriation and shall be deemed amended, effective as of the effective date of such Appropriation, such that the definition of the Premises shall include only that portion of the Premises that is not subject to such
Appropriation. As of the effective date of such Appropriation, the Base Rent shall be adjusted proportionately to the amount of the Premises that has been Appropriated. Lessee, as promptly as practicable and with all due diligence, shall cause the
repair or reconstruction of or the making of Alterations to the Improvements as necessary to restore the Improvements to an economically viable whole capable of operation in accordance with this Lease.



Section 21.4 Damage or Destruction; Duty to Restore. If the Premises
or the Improvements, or any portion thereof, are damaged or destroyed at any time during the Term and this Lease is not terminated by either party pursuant to and in accordance with this Article 21, Lessee, as promptly as practicable and with all
due diligence, shall cause the repair, reconstruction and replacement of the Improvements as nearly as possible given the circumstances and then-Applicable Law to their condition immediately prior to such damage or destruction and, except as
otherwise approved in writing by Lessor or precluded by then-Applicable Law, to their same general appearance. Notwithstanding the foregoing, Lessee shall have the right to elect not to restore any single building that is damaged where the positive
difference between the cost to repair and restore the building to substantially the same condition as existed immediately prior to such damage and the net amount of insurance proceeds actually recovered by Lessee and available to pay for restoration
is reasonably estimated to exceed thirty-three percent (33%) of the Full Replacement Insurable Value of such building. If Lessee elects not to restore such building pursuant to the foregoing right, then the following shall apply: (a) Lessee shall
cause such building to be demolished and removed in accordance with Applicable Law; (b) the amount of Base Rent shall not be changed or abated; (c) insurance



42



---

proceeds recovered on account of such damage shall first be used to prepay Base Rent in accordance with Section 6.2(c) to the extent that Base Rent has not
already been prepaid, but only to the extent that the amount of Base Rent that can be prepaid can actually be determined, and any remaining insurance proceeds shall be paid to Lessee. The foregoing shall not apply where multiple buildings are
damaged in the same casualty, or in the case of the subsequent damage to one building once Lessee has made the foregoing election with respect to a previously damaged building, it being the intention of the parties that at all times during the Term
there are at least three (3) buildings comprising the Improvements.



Section 21.5 Performance of Repairs and Restoration. All repairs and restoration shall be performed in accordance with the provisions of Article 11 of this Lease (as applicable). Except as otherwise provided herein, all insurance
proceeds and all Awards received by or payable to any party with respect to any casualty or to the repairs needed to repair the Premises following a partial Appropriation (except proceeds of insurance carried by sublessees under Permitted Subleases
covering loss or damage of their personal property), less actual costs and expenses incurred in connection with the collection thereof, shall be applied to the costs of repair and restoration of the Premises and the Improvements in accordance with
the provisions of this Article 21 and in compliance with Article 11 (as applicable). All such insurance proceeds shall be made available to Lessee in monthly draws during the repair of the Premises, which shall be available upon submission by Lessee
of written request accompanied by reasonably detailed invoices and customary lien releases from Lessees contractor. Lessee shall pay any amount by which the Award or insurance proceeds received as a result of such damage or Appropriation, less
the costs and expenses incurred in connection with the collection thereof, are insufficient to pay the entire cost of such repair and restoration.



Section 21.6 Option to Terminate Upon Damage or Destruction. Lessee shall have the option to terminate this Lease, exercisable as provided below,
upon the occurrence of any of the following: (a) any damage to or destruction of the Premises or the Improvements or any portion thereof at any time during the Term where the positive difference between the cost to repair and restore the same to
substantially the same condition as existed immediately prior to such occurrence and the net amount of insurance proceeds actually recovered by Lessee and available to pay for restoration is reasonably estimated to exceed thirty-three percent (33%)
of Full Replacement Insurable Value of all Improvements on the Premises; (b) any damage to or destruction of the Premises or the Improvements occurring during the last ten (10) Lease Years where the positive difference between the cost to repair and
restore the same to substantially the same condition as existed immediately prior to such occurrence and the net amount of insurance proceeds actually recovered by Lessee and available to pay for restoration is reasonably estimated to exceed fifteen
percent (15%) of Full Replacement Insurable Value of all Improvements on the Premises; or (c) any damage to or destruction of the Premises or the Improvements occurring during the last five (5) Lease Years.



Section 21.7 Option to Terminate upon Appropriation. If during the
Term the entire Premises or such portion thereof shall be Appropriated such that the Appropriation makes the continued operation of the remaining portion of the Premises not capable of being restored to an economically viable whole for the
purposes permitted hereunder, then, in either such case, Lessee shall have the option to terminate this Lease.



43



---

Section 21.8 Termination; Lessees Obligation to Restore; Arbitration. Lessee may exercise
its option to terminate this Lease pursuant to this Article 21 by giving written notice to Lessor within ninety (90) days after the occurrence of the event of damage or destruction, or the Appropriation, as the case may be. If Lessee elects to
terminate this Lease pursuant to this Article 21, Lessee shall surrender the Premises to Lessor in accordance with the provisions of Article 27, except to the extent the damage or destruction prevents Lessee from so doing. Lessees obligations
under this Article 21 shall survive the termination of this Lease. All proceeds of insurance payable with respect to damage to, or destruction of the Improvements and other property located on the Premises, after payment of costs and expenses of
collection thereof, shall first be applied to the costs of demolition, removal, restoration, and remediation, as appropriate, depending on the extent of the damage, destruction or Appropriation, with the balance, if any, of such insurance proceeds,
to be distributed as provided in Section 21.10. All Awards with respect to Lessees interests with respect to such Appropriation shall be distributed as provided in Section 21.10. Should Lessor and Lessee for any reason disagree as to whether
the conditions provided in this Article 21 to the parties rights to elect to terminate this Lease have occurred, the matter shall be determined by arbitration pursuant to Article 36 hereof.



Section 21.9 Determination of Award. The amount of the Award due to
Lessor and Lessee as a result of Appropriation shall be separately determined by the court having jurisdiction over such proceedings based on the following: Lessor shall be entitled to that portion of the Award attributable to the value of the fee
interest in the Premises (or portion thereof subject to Appropriation, in case of a partial Appropriation) subject to this Lease, and to the value of Lessors reversionary interest in the Improvements (or portion thereof subject to
Appropriation, in case of a partial Appropriation), as determined by the court; Lessee shall be entitled to that portion of the Award attributable to the value of Lessees leasehold interest in the Premises (or portion thereof subject to
Appropriation, in case of a partial Appropriation) and to the value of Lessees interest in the Improvements (or portion thereof subject to Appropriation, in case of a partial Appropriation), as determined by the court.



Section 21.10 Excess Proceeds and Awards for Lessees Interests.
If the total Award made in connection with any Appropriation for Lessees interests, and for severance damages to both Lessees and Lessors interests, exceeds the amount necessary to repair, restore, reconstruct or demolish
Alterations as required under this Article 21 in a case where this Lease is not terminated, or if there are proceeds of insurance in excess of that required to repair, restore, reconstruct or demolish the Premises and the Improvements as required
under this Article 21 or Article 27, upon receipt by Lessor of satisfactory evidence that the work of repair, restoration, reconstruction or demolition required under this Article 21 has been fully completed and paid for in accordance with the
provisions of Article 11 and that the last day for filing any mechanics or materialmens liens has passed without the filing of any, or if filed, any such lien has been released, any remaining Award or proceeds of insurance shall be paid
to Lessee and the holders of Leasehold Mortgages as their interests may appear. In case of an Award with respect to Lessees interests with respect to an Appropriation in a case where this Lease is terminated, any such Award shall be paid to
Lessee and the holders of Leasehold Mortgages as their interests may appear.



44



---

Section 21.11 Right to Participate in Settlement. Lessor and Lessee shall both have the right to
participate in the settlement or compromise of any insurance proceeds and Awards. If in any Appropriation the court does not make the allocation of Awards referred to in Section 21.9 and the parties cannot agree upon such allocations, such
allocations shall be determined by arbitration pursuant to Article 36.



Section 21.12 Emergency Repairs. If a casualty occurs there is a substantial possibility that immediate emergency repairs will be required to eliminate defective or dangerous conditions and to comply with Applicable Laws pending
settlement of insurance claims and prior to procuring bids for performance of restoration work. Notwithstanding any provision of this Article 21 to the contrary, Lessee shall promptly undertake such emergency repair work after a casualty as is
necessary or appropriate under the circumstances to eliminate defective or dangerous conditions and to comply with Applicable Laws and any proceeds of insurance shall first be applied to reimburse Lessee for the cost of such emergency repair work.



ARTICLE 22.

ASSIGNMENT



Section 22.1 Consent Required. Except as otherwise permitted in this Article 22 or in Articles 23 or 24, Lessee shall not directly or indirectly,
in whole or in part, voluntarily or by operation of law, sell, assign, encumber, pledge or otherwise transfer or hypothecate its interest in or rights with respect to the Premises or Lessees leasehold estate therein or the Improvements (any of
the foregoing being herein referred to as a Transfer without the prior written consent of Lessor, which consent shall not be unreasonably withheld or delayed. Notwithstanding the foregoing, Lessors consent shall not
be required for a Transfer to any of the following: (i) an Affiliate of Lessee; (ii) a successor corporation related to Lessee by merger, consolidation, or non-bankruptcy reorganization; or (iii) a purchaser of substantially all of the assets of the
business being operated by Lessee at the Premises. Lessor shall approve or disapprove any proposed Transfer within fifteen (15) business days after receipt of Lessees written request for approval (except as otherwise provided in Section 22.4),
which request shall be deemed complete and delivered only if it (a) identifies the proposed assignee, (b) includes a copy of the proposed assignment documentation, and (c) includes reasonably detailed information regarding the financial condition of
the proposed assignee.



(a) Conditions to Approval.
Without limiting any other reasonable basis for denial of consent to a Transfer, Lessee agrees that it shall be conclusively presumed to be reasonable for Lessor to consider the following requirements in determining whether or not to consent to a
proposed Transfer: (i) no Event of Default shall have occurred and remain uncured, (ii) Lessee shall have complied with all provisions of this Article 22, including Section 22.4, (iii) the use of the Premises by the transferee shall comply with the
provisions of this Lease, (iv) the proposed transferee (or those entities or persons in a position to control business decisions of the transferee, or any property manager or investment advisor engaged by it to manage its interest in the Premises)
shall have a business reputation appropriate to the Stanford Research Park, and be experienced in the ownership, management and operation of First Class properties similar to the Premises, and (v) the proposed transferee shall be capable financially
of performing Lessees obligations under this Lease and all other obligations relating to the Premises.



45



---

(b) Transfers of Ownership Interest. Notwithstanding anything contained herein, the term
Transfer shall include any transfer, in one transaction or in a series of related transactions, to one person or entity or to a group of related persons or entities, of ownership of more than fifty percent (50%) of the shares of stock of
Lessee (if it is a corporation) that are issued, outstanding, and entitled to vote for the election of directors, or, if Lessee is not a corporation, the partnership, membership, or other beneficial interests of the entity that is Lessee, if such
transferee (or an Affiliate of such transferee) does not intend, in good faith, to use and occupy at least fifty percent (50%) of the building area of the Improvements on the Premises for use in its trade or business, and does not intend to sublease
more than fifty percent (50%) of such space to third party tenants for the purpose of obtaining rental income from investment property. The provisions of this subsection 22.l(b) shall not apply to any Transfer to TIBCO Software, Inc., or any of its
Affiliates.



Section 22.2 Assumption in Writing. Upon
any Transfer, Lessee shall deliver to Lessor a fully executed copy of the assignment instrument, pursuant to which the proposed transferee shall unconditionally assume and agree to perform and observe all covenants and conditions to be performed and
observed by Lessee under this Lease. The consent by Lessor to any Transfer shall not relieve Lessee from the obligation to obtain Lessors express consent to any other Transfer requiring Lessors consent. Any Transfer or attempted Transfer
that fails to comply with this Article 22 shall be void and, at the option of Lessor, shall constitute an Event of Default. Upon completing a Transfer that complies with this Article 22 where the transferors entire interest in the leasehold
created by this Lease is transferred to the transferee, the transferor shall thereupon be released from any liability for the performance of the obligations of the Lessee under this Lease which arise from and after the date of such Transfer.



Section 22.3 Entire Interest. Lessee shall not be
entitled to Transfer less than all of its interest under this Lease or to Transfer its title to the Improvements separately from its interest under this Lease.



Section 22.4 Lessors Rights of First Offer and First Refusal.



(a) Before Lessee commences any marketing activity in anticipation of a Transfer, Lessor shall have a right of first offer
in connection with such proposed Transfer, and Lessee shall first deliver to Lessor a written notice (the Offer) stating all of the material business terms and conditions upon which Lessee would agree to transfer the
Premises to Lessor (which may include the right of Lessee or a Lessee Affiliate to lease back some or all of the Premises following the Transfer and the right to terminate existing leases with Affiliates of Lessee). Lessor shall then have ten (10)
business days to respond to the Offer by written notice to Lessee. Lessees failure to respond within ten (10) business days shall be deemed an election not to accept the Offer.



(b) If, within such ten (10) business day period, Lessor accepts the Offer in writing, then Lessor and Lessee shall work in
good faith to complete a purchase and sale contract



46



---

in substantially the form of the Agreement to Lease, together with such other appropriate documentation as may be necessary to effect the Transfer to Lessor,
and to close such Transfer within sixty (60) days after Lessors written notice of acceptance of the Offer; provided, however, that the closing date may be extended for an additional fifteen (15) days by Lessor in the event Lessor identifies a
commercially reasonable due diligence item that requires more time to resolve. If Lessor accepts such Offer, Lessor shall promptly commence and diligently pursue its due diligence investigations. The Transfer shall be consummated by Lessees
delivery to Lessor of (i) a good and sufficient assignment of lease, in recordable form, assigning to Lessor all of Lessees right, title and interest in, to and under the Lease, free and clear of any and all Liens except for title exceptions
existing as of the Commencement Date or as otherwise permitted hereunder, (ii) a good and sufficient assignment of all of Lessees rights as landlord under any subleases affecting the Premises that are not terminated by Lessee before or
concurrently with the consummation of the Transfer, and (iii) a quitclaim deed to the Improvements. Lessor shall pay the consideration agreed upon in cash at the closing of the Transfer or otherwise in the manner specified in the Offer.



(c) If, within such ten (10) business day period, (i) Lessor rejects the
Offer in writing, or (ii) does not give Lessee written notice accepting the Offer, or (iii) if (despite the good faith efforts of both parties) a purchase and sale contract is not completed and the closing pursuant thereto does not occur within the
time frames identified in subsection (b) above (and such failure is not the result of a breach of such contract by Lessee), then in any such event Lessee may at any time within nine (9) months from Lessees receipt of Lessors written
notice rejecting the Offer or after the expiration of the ten (10) business day response period, or after the expiration of the applicable contract negotiation and closing period (each, a Terminating Event), and subject to
all of the conditions, restrictions and terms of this Article 22, Transfer its interest to a third party, provided that the terms and conditions of such Transfer shall not be materially different than those set forth in the Offer. The parties agree
that materially different shall mean that the rent and other consideration and concessions offered by the third party shall not be less than 95% of the Offer, taking into account all terms and conditions that would affect the economics
of the proposed Transfer. If the terms and conditions of any third party offer made within nine (9) months after a Terminating Event are materially different, then Lessee shall not effect the Transfer with the third party unless (i) Lessee first
delivers to Lessor a second offer in writing stating how the third party offer is materially different from the Offer (the Re-offer), and (ii) Lessor rejects the Re-offer in writing, or does not give Lessee written notice
accepting the Re-offer, within ten (10) business days of Lessors receipt of the Re-offer, failing which Lessee may complete the Transfer to a third party upon terms and conditions not materially different from the Re-Offer. Upon the expiration
of the 9-month period which commenced with the Terminating Event, the provisions of Section 22.4(a) shall again apply and Lessors right of first offer shall be reinstated.



(d) This Section 22.4 shall not apply to, and Lessee shall have no obligation to make any Offer to Lessor with respect to,
any Transfer of the Premises (i) to an Affiliate of Lessee or to TIBCO Software, Inc. or any of its Affiliates, (ii) made in connection with a merger, consolidation, or non-bankruptcy reorganization; or (iii) made in connection with a sale of
substantially all of the assets of Lessee related to the business being operated by Lessee at the Premises provided the transferee will actually continue to occupy the Premises for the purpose of the conduct of its business at the Premises.

Code Section 1951.2, including without limitation, the right to recover the worth at the time of award of the amount by which the Rent and other charges payable hereunder for the balance of the Term after the time of award exceed the amount of such

---

does not terminate Lessees right to possession. Acts of maintenance or preservation, efforts to relet the Premises or the appointment of a receiver
upon Lessors initiative to protect its interest under this Lease shall not constitute a termination of Lessees right to possession.

jurisdiction enters a final judgment ordering Lessee to vacate the Premises and deliver possession to Lessor, Lessee shall have the right to cure such Event of Default and thereby reinstate this Lease as if such Event of Default had not occurred by
paying to Lessor all amounts then due Lessor pursuant to this Lease and otherwise curing any non-monetary Event of Default that then exists.

Lease within thirty (30) days after receipt of written notice from Lessee specifying in reasonable detail the nature of Lessors breach; provided, however, that if the nature of Lessors breach is such that more than thirty (30) days are
required for performance, then Lessor shall not be in default if Lessor commences the cure of such breach within such thirty (30) day period and thereafter diligently prosecutes the same to completion. Lessee shall be entitled to actual (but not
consequential) damages in the event of an uncured default by Landlord, but shall not have any right to terminate this Lease as a result of any Landlord default.

municipal time limitation. Lessor shall not be required to inquire into the correctness of the amount or validity of any payable or lien that may be paid by Lessor, and Lessor shall be duly protected in paying the amount of any such payable or lien
claimed, and, in such event, Lessor shall also have the full authority, in Lessors sole judgment and discretion and without prior notice to or approval by Lessee, to settle or compromise any such lien or payable. Any act or thing done by
Lessor pursuant to the provisions of this Article 26 shall not be or be construed as a waiver of any default by Lessee, or as a waiver of any term, covenant, agreement or condition herein contained or of the performance thereof.

Section 40.12 Termination Not Merger. The voluntary sale or other surrender of this Lease by Lessee to Lessor, or a mutual cancellation thereof, or the termination thereof by Lessor pursuant to any provision contained herein, shall

Section 40.14 Survival. The obligations of this Lease shall survive the expiration of the Term to the extent necessary to implement any requirement for the performance of obligations or forbearance of an act by
either party hereto which has not been completed prior to the termination of this Lease. Such survival shall be to the extent reasonably necessary to fulfill the intent thereof, or if specified, to the extent of such specification, as same is
reasonably necessary to perform the obligations and/or forbearance of an act set forth in such term, covenant or condition. Notwithstanding the foregoing, in the event a specific term, covenant or condition is expressly provided for in such a clear
fashion as to indicate that such performance of an obligation or forbearance of an act is no longer required, then the specific shall govern over this general provisions of this Lease.

DETERMINATION OF FAIR MARKET RENTAL VALUE



(a) If within the 30-day negotiating period Lessor and Lessee cannot reach agreement as to the Fair Market Rental Value, they shall each select one
appraiser to determine the Fair Market Rental Value. Each such appraiser shall arrive at a determination of the Fair Market Rental Value and submit his or her conclusions to Lessor and Lessee within thirty (30) days after the expiration of the
initial 30-day negotiating period.



(b) If only one appraisal
is submitted within the requisite time period, it shall be deemed to be the Fair Market Rental Value. If both appraisals are submitted within such time period, and if the two appraisals so submitted differ by less than ten (10) percent of the higher
of the two, the average of the two shall be the Fair Market Rental Value. If the two appraisals differ by more than ten (10) percent of the higher of the two, then the two appraisers shall immediately select a third appraiser who will within thirty
(30) days of his or her selection make a determination of the Fair Market Rental Value and submit such determination to Lessor and Lessee. This third appraisal will then be averaged with the closer of the previous two appraisals and the result shall
be the Fair Market Rental Value.



(c) All appraisers specified
pursuant hereto shall be members of the American Institute of Real Estate Appraisers with not less than ten (10) years experience appraising office, research and development and industrial properties in California. Each party shall pay the cost of
the appraiser selected by such party and one-half of the cost of the third appraiser plus one-half of any other costs incurred in the determination.

TRI-PARTY AGREEMENT



THIS AGREEMENT is entered into as of June 25, 2003, by and between THE BOARD OF TRUSTEES OF THE LELAND STANFORD JUNIOR UNIVERSITY, a body having corporate
powers under the laws of the State of California (Lessor), 3301 Hillview Holdings, Inc., a Delaware corporation (Lessee) and SunAmerica Life Insurance Company, an Arizona corporation
(Lender).



RECITALS



A. Lessor is the owner of that certain real property, being a portion of the
lands of The Leland Stanford Junior University, located in the County of Santa Clara, State of California, and more particularly described in attached Exhibit A (the Premises) and the lessor under that certain ground
lease of the Premises dated as of June 25, 2003, by and between Lessor and Lessee (the Lease).



B. Lessee desires to obtain a loan from Lender in the principal amount of Fifty Four Million Dollars ($54,000,000.00) (the Loan)
and to encumber its leasehold interest under the Lease as security for the Loan.



C. Lender is willing to make the Loan to Lessee secured by Lessees leasehold interest under the Lease provided that Lessor consents thereto and agrees to the provisions of this Agreement.



D. Lessor is willing to consent to the encumbering of Lessees leasehold
interest under the Lease as security for the Loan on the terms and conditions set forth in this Agreement.



AGREEMENT



NOW THEREFORE, in consideration of the premises and other mutual valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto hereby agree as follows:



1. Encumbrance of Leasehold Interest.Subject to the terms and
conditions of this Agreement, Lessor hereby consents to the encumbering of Lessees leasehold interest under the Lease pursuant to a mortgage or deed of trust as security for the Loan provided that the outstanding amount of the Loan secured
thereby shall not exceed $54,000,000.00, plus accrued interest and other charges allowed thereunder (the mortgage, deed of trust or other security instrument permitted hereunder being herein referred to as the Leasehold
Mortgage). In no event shall any interest of Lessor in the Premises be subject or subordinate to any lien or encumbrance of the Leasehold Mortgage or any other mortgage, deed of trust, or other security instrument.



1



---

2. Parties Obligations.During the continuance of the Leasehold Mortgage until such time as
the lien of the Leasehold Mortgage shall have been extinguished, the parties agree as follows:



(a) Modifications to Lease.Lessor shall not agree to any mutual termination nor accept any surrender of the Lease, except upon the expiration of
the term of the Lease or its termination pursuant to any express provision of the Lease, nor shall any material amendment or modification of the Lease be binding upon Lender or any purchaser in foreclosure from Lender or any deed in lieu
recipient or any successor or assign of such purchaser in foreclosure or deed in lieu recipient (herein, collectively, a Purchaser),unless Lender has given its prior written consent to such amendment or
modification, which consent shall not be unreasonably withheld or delayed.



(b) Insurance and Condemnation.Lender may be a named insured on any fire and other hazard insurance policies carried by Lessee and covering the Premises. All proceeds of any such insurance policies shall be
held by Lessor, or at the request of Lender, by a trust company satisfactory to Lessor and Lender. In the event that at any time prior to expiration of the term of the Lease there shall be a partial or total destruction of the buildings and
improvements then on the Premises from any cause, neither Lessor nor Lessee shall have the right to terminate the Lease, but Lesseeshall diligently restore and rehabilitate said buildings and improvements pursuant to plans and specifications
approved by Lessor and Lender in writing, which approval shall not be unreasonably withheld or delayed, and, except as hereinafter provided, all proceeds of all property damage insurance shall be disbursed to Lessee upon such terms as Lessor and
Lender may agree, for the purpose of restoring and rehabilitating said buildings and improvements. Should the proceeds of such insurance exceed the cost of such restoration and rehabilitation, the balance shall be paid to Lender to be credited by
Lender as a payment on account of the Loan, and the remaining balance, if any, shall be paid in accordance with the Lease. Proceeds of any business or rental interruption insurance carried by Lessee with respect to the Premises shall be applied
first to any unpaid obligations of Lessee under the Lease, then to any unpaid obligations under the Leasehold Mortgage and any remaining balance may be paid to Lessee. In the event that any portion of the Premises is taken in condemnation, no
election to terminate the Lease by Lessee may be made without the prior written consent of Lender. In the event of such condemnation, any awards which under the provisions of the Lease are payable to Lessee shall be payable to Lender.



(c) Lenders Right to Perform.Lender shall have the right, but
not the obligation, at any time prior to termination of the Lease to pay all rental due thereunder, to provide any insurance and make any other payments, to make any repairs and improvements and do any other act or thing required of Lessee
thereunder, and to do any act or thing which may be necessary and proper to be done in the performance and observance of the covenants, conditions and agreements thereof to prevent the termination of the Lease. All payments so made and all things so
done and performed by Lender shall be as effective as a performance under the Lease and to prevent a termination of the Lease as the same would have been if made, done and performed by Lessee instead of by Lender.

---

(d) Lessees Default.Should any default occur under the Lease, Lender shall have thirty
(30) days after receipt of written notice from Lessor setting forth the nature of such default, and, if the default is such that possession of the Premises may be necessary to remedy the default, a reasonable time after the expiration of such thirty
(30) day period within which to remedy such default, provided that (i) Lender shall have fully cured any default in the payment of any monetary obligations of Lessee under the Lease, within such thirty (30) day period and shall
continue to pay currently such monetary obligations as and when the same are due, and (ii) Lender shall have given Lessor written notice that Lender intends to take action to acquire Lessees leasehold estate, and, subject to the provisions of
Section 2(i) below, commenced foreclosure or other appropriate proceedings in the nature thereof within a reasonable period, and shall thereafter diligently and continuously prosecute such proceedings to completion.



(e) Lenders Right to Cure.A default under the Lease which in
the nature thereof cannot be remedied by Lender shall be deemed to be remedied if (i) within thirty (30) days after receiving written notice from Lessor of such default, Lender shall have given Lessor written notice that Lender intends to take
action to acquire Lessees interest under the Lease and, subject to the provisions of Section 2(i) below, commenced foreclosure or other appropriate proceedings in the nature thereof in a reasonable period, and Lender shall thereafter
diligently and continuously prosecute any such proceedings to completion, (ii) Lender shall have fully cured any default in the payment of any monetary obligations of Lessee under the Lease within such thirty (30) day period and shall thereafter
continue to faithfully perform all such monetary obligations, and (iii) after gaining possession of the Premises, Lender shall perform all of the obligations of Lessee under the Lease as and when the same are due and cure any defaults that are
curable by Lender but that require possession of the Premises to cure, such cure to be effected within thirty (30) days after gaining possession, or such longer period of time as is reasonably necessary to effect such cure using all due diligence.



(f) Notices.Lessor shall mail to Lender a duplicate
copy by certified mail of any and all notices which Lessor may from time to time give to or serve upon Lessee pursuant to the provisions of the Lease; and no notice by Lessor to Lessee hereunder shall be deemed to have been given as to Lender unless
and until a copy thereof has been mailed to Lender.



(g)
Foreclosure.Subject to the provisions of this subsection (g) and subsection (i) below, foreclosure of a Leasehold Mortgage or any sale thereunder, whether by judicial proceedings or by virtue of any power of sale contained in the Leasehold
Mortgage, or any conveyance of the leasehold interest under the Lease from Lessee to Lender by virtue or in lieu of foreclosure or other appropriate proceedings in the nature thereof, shall not require the consent of Lessor,shall not be
subject to the provisions of Section 22.4 of the Lease, and shall not constitute a breach of any provision of or a default under the Lease and upon such foreclosure, sale or conveyance, Lessor shall recognize Lender or any other Purchaser, as the
Lessee under the Lease; provided:



(i) Lender
shall have fully complied with the provisions of this Agreement applicable prior to gaining possession of the Premises and Lender or the Purchaser who becomes the Lessee under the Lease shall comply with the provisions of this Agreement applicable
after gaining possession of the Premises;



3



---

(ii) Lender or the Purchaser who becomes the Lessee under the Lease shall be responsible
for taking such actions as shall be necessary to obtain possession of the Premises; and



(iii) Lender or the Purchaser who becomes the Lessee under the Lease shall execute, acknowledge and deliver to Lessor an instrument in
form reasonably satisfactory to Lessor pursuant to which Lender or the Purchaser expressly assumes all obligations of the Lessee under the Lease, which instrument shall contain the same representation and release by the entity assuming the
Lessees obligations under the Lease as are made by Lender pursuant to Section 3 of this Agreement.



If there are two or more Leasehold Mortgages or foreclosure sale purchasers (whether of the same or different Leasehold Mortgages), Lessor shall have no duty or obligation whatsoever to determine the relative
priorities of such Leasehold Mortgages or the rights of the different holders thereof and/or foreclosure sale purchasers. If Lender becomes the Lessee under the Lease, or under any new lease obtained pursuant to subsection (h) below, Lender shall
not be personally liable for the obligations of the Lessee under the Lease accruing prior to or after the period of time that Lender is the Lessee thereunder.



(h) Rejection of Lease.Should the Lease be terminated by reason of any rejection of the Lease in a bankruptcy proceeding, Lessor shall,
subject to the terms and conditions of this subsection (h) and subsection (i) below, upon written request by Lender to Lessor made within thirty (30) days after such termination, execute and deliver a new lease of the Premises to Lender for the
remainder of the term of the Lease with the same covenants, conditions and agreements (except for any requirements which have been satisfied by the Lessee prior to termination) as are contained therein; provided, however, that Lessors
execution and delivery of such new lease of the Premises shall be made without representation or warranty of any kind or nature whatsoever, either express or implied, including without limitation, any representation or warranty regarding title to
the Premises or the priority of such new lease; Lessors obligations and liability under such new lease shall not be greater than if the Lease had not terminated and Lender had become the Lessee thereunder, and the new lease shall contain the
same representation and release made by the entity that is the lessee thereunder as are made by Lender under Section 3 of this Agreement. Lessors delivery of the Premises to Lender pursuant to such new lease shall be made without
representation or warranty of any kind or nature whatsoever, either express or implied; and Lender shall take the Premises as is in their then current condition. Upon execution and delivery of such new lease, Lender, at its sole cost and
expense, shall be responsible for taking such action as shall be necessary to cancel and discharge the Lease and to remove the Lessee named therein and any other occupant from the Premises. Lessors obligation to enter into such new lease of
the Premises with Lender shall be conditioned as follows:

---

(i) Lender shall have complied with the provisions of this Agreement applicable prior to
the gaining of possession and shall comply with the provisions of this Agreement applicable after gaining possession of the Premises;



(ii) if more than one holder of a Leasehold Mortgage claims to be the Lender and requests such new lease, Lessor shall have no duty or
obligation whatsoever to determine the relative priority of such Leasehold Mortgages, and in the event of any dispute between or among the holders thereof, Lessor shall have no obligation to enter into any such new lease if such dispute is not
resolved to the sole satisfaction of Lessor within ninety (90) days after the date of termination of the Lease; and



(iii) Lender shall pay all costs and expenses of Lessor, including without limitation, reasonable attorneys fees, real property
transfer taxes and any escrow fees and recording charges, incurred in connection with the preparation and execution of such new lease and any conveyances related thereto.



3. Hazardous Substances.By execution of this Agreement, Lender hereby represents to Lessor as follows: Lender is
aware that detectable amounts of hazardous substances and groundwater contaminants have come to be located beneath and/or in the vicinity of the Premises. Lender has made such investigations and inquiries as it deems appropriate to ascertain the
effects, if any, of such substances and contaminants on the Premises and persons using the Premises. Lessor makes no representation or warranty with regard to the environmental condition of the Premises. Lender hereby covenants and agrees not to sue
and forever releases and discharges Lessor, and its trustees, officers, directors, agents and employees for and from any and all claims, losses, damages, causes of action and liabilities, arising out of hazardous substances or groundwater
contamination presently existing on, under, or emanating from or onto the Premises. Lender understands and expressly waives any rights or benefits available under Section 1542 of the Civil Code of California or any similar provision in any other
jurisdiction. Section 1542 provides substantially as follows: A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have
materially affected his settlement with the debtor.



4.
