($80,300.28) (the “Security Deposit”), in cash, as security for the performance by Subtenant of the terms and conditions of this Sublease. If Subtenant fails to pay Rent or other charges due hereunder or otherwise defaults with respect to
any 

 provision of this Sublease, then Sublandlord may draw upon, use, apply or retain all or any portion of the Security
Deposit for the payment of any Rent or other charge in default, for the payment of any other sum which Sublandlord has become obligated to pay by reason of Subtenant’s default, or to compensate Sublandlord for any loss or damage which
Sublandlord has suffered thereby. If Sublandlord so uses or applies all or any portion of the Security Deposit, then Subtenant, within three (3) days after demand therefore, shall deposit cash with Sublandlord in the amount required to restore the
Security Deposit to the full amount stated above. Upon the expiration of this Sublease, if Subtenant is not in default, Sublandlord shall return to Subtenant so much of the Security Deposit as has not been applied by Sublandlord pursuant to this
paragraph, or which is not otherwise required to cure Subtenant’s defaults. 
  
 6. Repairs: The parties acknowledge and agree that Subtenant is subleasing the Subleased Premises on an “as is” basis, and that Sublandlord has made no representations or warranties with respect to
the condition of the Subleased Premises. Sublandlord shall have no obligation whatsoever to make or pay the cost of any alterations, improvements or repairs to the Subleased Premises, including, without limitation, any improvement or repair required
to comply with any law, regulation, building code or ordinance (including the Americans with Disabilities Act of 1990). Sublandlord shall not be responsible for performance of any repairs required to be performed by Landlord under the terms of the
Lease; provided, however, that Sublandlord agrees that Subtenant shall be entitled to receive all services and repairs to be provided by Landlord to Sublandlord under the Lease and Sublandlord shall use commercially reasonable efforts to cause
Landlord to perform or obtain Landlord’s performance. Sublandlord shall cooperate with Subtenant to provide Subtenant with the benefit of any warranties or service contracts that Sublandlord holds applicable to systems that Subtenant is
responsible for maintaining in the Subleased Premises. 
  
 7.
Indemnity: Except to the extent caused by the negligence or willful misconduct of Sublandlord, its agents, employees, contractors or invitees, Subtenant shall indemnify, defend with counsel reasonably acceptable to Sublandlord, protect and
hold Sublandlord harmless from and against any and all claims, liabilities, losses, damages, costs and expenses (including reasonable attorneys’ and experts’ fees), to the extent Sublandlord shall become liable for same to Landlord and
which are due to: (a) the use, occupancy or condition of the Subleased Premises by Subtenant; or (b) the negligence or willful misconduct of Subtenant or its employees, contractors, agents or invitees; or (c) a breach of Subtenant’s obligations
under this Sublease or the provisions of the Lease. Subtenant’s indemnification of Sublandlord shall survive termination of this Sublease. 
  
 8. Assignment and Subletting. Subtenant may not assign this Sublease, sublet the Subleased Premises, transfer any interest of Subtenant therein or
permit the use of the Subleased Premises by another party without the prior written consent of Sublandlord (which consent shall not be unreasonably withheld or delayed), and Landlord in accordance with the provisions of Section 18 of the Lease, as
incorporated herein. 
  
 If no default on the part of Subtenant is
in existence beyond any applicable cure period, Subtenant may, without Sublandlord’s consent, assign this Sublease or sublet any portion of the Subleased Premises to a parent or subsidiary of Subtenant, or to an entity into which Subtenant is
merged or consolidated or to an entity to which substantially all of Subtenant’s assets are transferred (“Corporate Affiliate”), without first obtaining Sublandlord’s written consent if Subtenant notifies Sublandlord at least ten
(10) business days prior to the proposed transaction, providing information 

 satisfactory to Sublandlord in order to determine the net worth of both the successor entity and of Subtenant immediately
prior to such assignment or sublease and showing the net worth of the successor to be at least equal to the net worth of Subtenant at the time of the transfer. 
  

9. Use: Subtenant may use the Subleased Premises only for office use, software research and development, storage and shipping of products,
marketing and non-retail sales and customer service and support in accordance with the municipal zoning requirements for the City of Sunnyvale and the terms of the Lease and ancillary uses permitted under applicable laws to the extent also permitted
by the Lease. Subtenant may use the Subleased Premises for the other purposes described in Section 6 of the Schedule in the Lease in accordance with the municipal zoning requirements for the City of Sunnyvale and the terms of the Lease only with the
prior written consent of Sublandlord, which consent shall not be unreasonably withheld or delayed. Subtenant shall not use, store, transport or dispose of any Hazardous Substance in or about the Subleased Premises other than normal quantities of
standard office products. Subtenant shall not violate any of the terms, provisions, conditions or requirements set forth in the Lease, whether or not the same are consistent with the terms and provisions of this Sublease. 
  
 10. Delivery and Acceptance: Sublandlord and Subtenant acknowledge
that (i) Subtenant currently occupies and is in possession of the Subleased Premises pursuant to a sublease with Applied Materials, Inc., (ii) the term of such sublease expires on August 31, 2003 and (iii) the Lease is scheduled to commence on
September 1, 2003. Possession of the Subleased Premises shall be deemed to be delivered to Subtenant on the commencement date of the Lease. If Sublandlord fails to deliver possession of the Subleased Premises to Subtenant on or before September 1,
2003 for any reason, then this Sublease shall not be void or voidable, nor shall Sublandlord be liable to Subtenant for any loss or damage; provided, however, that in such event, Rent shall abate until Sublandlord delivers possession of the
Subleased Premises to Subtenant. By taking possession of the Subleased Premises, Subtenant conclusively presumptively shall be deemed to have accepted the Subleased Premises in their as-is, then-existing condition. 
  
 11. Improvements: The parties hereto acknowledge and agree that
Subtenant is responsible for the construction of any improvements in the Subleased Premises (“Subleased Premises Improvements”) at Subtenant’s sole cost and expense. No alteration or improvements shall be made to the Subleased
Premises without the prior written consent of Landlord and and/or Sublandlord and in strict accordance with Section 5 of the Lease, as incorporated herein; provided, however, that the consent of Sublandlord and Landlord shall not be required if (a)
the cost of the alteration or improvement to the Subleased Premises is less than $25,000 per occurrence, (b) such work does not impact the base structural components or systems of the Subleased Premises, (c) such work does not impact any other
tenant’s premises, and (d) such work is not visible from outside of the Subleased Premises. Otherwise, Subtenant shall obtain the consent of Landlord and Sublandlord which consent shall not be unreasonably withheld. 
  
 12. Release and Waiver of Subrogation: The release and waiver of
subrogation in Section 9A of the Lease, as incorporated herein, shall be binding on the parties hereto. Each party shall give notice to their respective insurance carriers that such a waiver of subrogation is contained in this Sublease.

cost and expense, during the Term the insurance required under Section 9C of the Lease to the extent same are applicable to the Subleased Premises. Subtenant shall name Landlord and Sublandlord and their respective building managers, agents,
mortgagees and ground lessors, if any, as additional insured’s on Subtenant’s liability policy. 
  
 14. Default: Subtenant shall be in material default of its obligations under this Sublease if any of the following events occur: 
  
 A. Subtenant fails to pay any Rent when due, when such failure continues for
three (3) days after written notice from Sublandlord to Subtenant that any such sum is was not paid when due; or 
  
 B. Subtenant fails to perform any term, covenant or condition of this Sublease (except those requiring payment of Rent) and fails to cure such breach
within twenty (20) days after delivery of a written notice specifying the nature of the breach; provided, however, that if more than twenty (20) days reasonably are required to remedy the failure, then Subtenant shall not be in default if Subtenant
commences the cure within the twenty (20) day period and thereafter completes the cure within ninety (90) days after the date of the notice; or 
  
 C. Subtenant commits any other act or omission which constitutes a default under the Lease, which has not been cured within the applicable grace period

 1.    LEASE AGREEMENT. On the terms stated in this Lease, Landlord leases the Premises

 A.    Commencement Date. Subject to
Sections l.C and l.D below, the commencement date (“Commencement Date”) for this Lease is the date set forth in the Schedule. Notwithstanding the foregoing, if Landlord fails to deliver possession of the portion of the Premises consisting
of Building C to Tenant on or before the Commencement Date vacant and otherwise in the condition required hereunder for any reason, then (i) this Lease shall not be void or voidable by either party, (ii) Landlord shall not be liable to Tenant for
any loss or damage resulting therefrom, and (iii) the Commencement Date with respect to the portion of the Premises consisting of Building C shall be revised to mean the date on which Landlord delivers possession of Building C to Tenant vacant and
otherwise in the condition required hereunder, and the Termination Date shall remain unchanged. Tenant acknowledges and agrees that, notwithstanding anything to the contrary in this Lease, its rights under this Lease with respect to Building C are
subject and subordinate in all respects to (i) the option of AMAT (as hereinafter defined) to extend the term of the AMAT Lease (as hereinafter defined) with respect to Building C its set forth in Section 31 of the AMAT Lease, and (ii) any other
agreement between Landlord and AM4T to extend the term of the AMAT Lease with respect to Building C whether or not reflected in the AMAT Lease or entered into after the date hereof and prior to March 1 , 2003. Landlord will use commercially
reasonable efforts to regain possession of Building C in the event that the term of the AMMAT Lease with respect to Building C is not extended as provided in subpart (i) or (ii) hereof for any reason whatsoever and Vitria (as hereinafter defined) or
any other occupant remains in occupancy following termination of the Vitria Sublease (as hereinafter defined) or the AMAT lease as to Building C, including the initiation of unlawful detainer proceedings. In the event the term of the AMAT Lease with
respect to Building C is not extended for any reason whatsoever and Landlord fails to deliver possession of Building C vacant and otherwise in the condition required hereunder within ninety (90) days after the estimated Commencement Date for
Building C set forth in Item 10 of the Schedule, then Tenant may, by written notice to Landlord, terminate this Lease with respect to Building C only. Upon any such termination. Landlord shall promptly return to Tenant S 146,696.30 representing the
portion of the Initial Security Deposit applicable to Building C. Upon request from Tenant. Landlord agrees to promptly inform Tenant as to whether the AMAT Lease has been extended. In the event that the AMAT Lease is extended as set forth in
subparts (i) or (ii) above, or this Lease is otherwise terminated as to Building C as expressly set forth in this Lease, references in this Lease to “Building C” shall be deemed deleted, “Premises” and “Building” shall
not include Building C, and the square footage, the Base Rent and other rental amounts, Tenant’s Proportionate Share, the number of parking spaces, the Initial Security Deposit and other similar amounts shall be proportionately reduced.

  
 B.    Termination Date. The
Termination Date (“Termination Date”) for this Lease is the date set forth in the Schedule. 
  
 C.    Effectiveness of Lease. Notwithstanding any provision in this Lease to the contrary, this Lease shall be expressly
subject to the following termination provisions: 
  

 1 

 (1)    Tenant’s Satisfaction of the Net Worth Test.
Unless Tenant provides Landlord with the Additional Security Deposit described below, Landlord shall have the right to terminate this Lease in the event Tenant fails to satisfy both of the following two tests: (a) Tenant’s “Net Worth”
as of the Commencement Date of this Lease shall be greater than its . Net Worth as of the Effective Date (as evidenced by the most current audited financial statements prepared by an independent accounting firm in accordance with generally accepted
accounting principles (“GAAP”) consistently applied which are available as of the Effective Date and the Commencement Date), and (b) in four of the five reporting quarters of Tenant immediately preceding the Commencement Date, Tenant shall
have reported positive net income on its income statements prepared in accordance with GMP for such quarterly reporting periods. In the event either of these tests is not satisfied as of the Commencement Date, then Landlord may elect to terminate
this Lease with written notice to Tenant, subject to Tenant’s surrender of the Premises in the condition required hereunder. Within one hundred eighty (180) days after Tenant’s receipt of such termination notice, Tenant shall surrender the
Premises in the condition required hereunder, provided that the Lease shall continue to be in effect and Tenant shall continue to pay all Rent and perform all other obligations hereunder until the Premises have been vacated and surrendered by Tenant
in the condition required hereunder. Notwithstanding the foregoing, in the event that Tenant fails to meet either of the foregoing tests, Tenant may prevent Landlord from so terminating this Lease by providing Landlord with an “Additional
Security Deposit” within thirty (30) days of Tenant’s receipt of Landlord’s termination notice. If Landlord receives such Additional Security Deposit after the thirty (30) day period following Tenant’s receipt of Landlord’s
termination notice, then Landlord may, in its sole and absolute discretion, withdraw and cancel the early termination of this Lease. The Additional Security Deposit shall be in an amount equal to six (6) months of the initial Base Rent and may be in
the form of a “Letter of Credit.” The Additional Security Deposit shall be added to the Initial Security Deposit described in Item No. 5 of the Schedule to this Lease and held by Landlord in the manner described in Section 22 below. Any
such Letter of Credit shall (i) be in the form of an unconditional and irrevocable letter of credit which is acceptable to Landlord, (ii) name Landlord as a beneficiary, (iii) expressly allow Landlord to draw upon it (including partial withdrawals)
at any time from time to time by delivering to the issuer written certification that Landlord is entitled to draw thereunder as a result of Tenant’s default (beyond any applicable grace, notice or cure period) hereunder, (iv) be drawable on an
FDIC-insured financial institution satisfactory to Landlord, (v) be redeemable in the State of California in one of the nine counties comprising the San Francisco-Oakland-San Jose area (the “Bay Area”), (vi) allow partial draws, and (vii)
be transferable to any successor to Landlord’s interest in this Lease at no cost to Landlord. At all times during the Term, the amount drawable under the Letter of Credit shall be equal or greater than the amount of the Additional Security
Deposit. If Tenant does not provide Landlord with a substitute Letter of Credit complying with all of the requirements hereof at least thirty (30) days before the stated expiration date of the current Letter of Credit, then Landlord shall have the
right to draw upon the current Letter of Credit and hold the funds drawn as part of the Additional Security Deposit; provided, however, so long as no default (beyond any applicable grace, notice or cure period) shall exist, Tenant may have an
additional thirty (30) days following Landlord’s draw on the current Letter of Credit in which to provide Landlord with a substitute Letter of Credit complying with each of the foregoing criteria, and upon such delivery, Landlord shall return
to Tenant an amount in cash (but without any interest thereon) equal to the lesser of the (x) amount drawn by Landlord under the current Letter of Credit, or (y) the face amount of the 

  

 2 

 
substitute Letter of Credit. In the event Landlord notifies Tenant in writing that the bank which issued the Letter of Credit has become financially
unacceptable (e.g., the bank is under investigation by governmental authorities, or has filed bankruptcy or reorganization proceedings, then Tenant shall have thirty (30) days to provide Landlord with a substitute Letter of Credit complying with all
of the requirements hereof. 
  
 (2)    Existing Subleases. Landlord and Applied Materials, Inc. (“AMAT”) entered into that certain Lease dated September 9, 1997 (the “AMAT Lease”) pursuant to which Landlord leased to AMAT all
of the buildings in the Project, including the Buildings which comprise the Premises under this Lease. The term of the AMAT Lease with respect to such Buildings shall terminate on August 31, 2003 (i.e., the day before the Commencement Date under
this Lease). AMAT and Tenant entered into that certain Sublease Agreement dated March 1999 (the “Proxim Sublease”), pursuant to which AMAT subleased a portion of the Premises consisting of Building A and Building B to Tenant for the
remainder of the term of the AMAT Lease as it relates to Building A and Building B. AMAT and Vitria Technology, Inc., a California corporation (“Vitria”) entered into that certain Sublease Agreement dated April 6, 1999 (the “Vitria
Sublease”), pursuant to which AMAT subleased the portion of the Premises consisting of Building C to Vitria for the remainder of the term of the AMAT Lease as it relates to Building C. Notwithstanding any provision herein to the contrary, this
Lease shall automatically terminate in the event the Proxim Sublease terminates due to Tenant’s failure to timely perform its obligations under the Proxim Sublease and thereafter neither party shall have any further rights or obligations
hereunder, except that Landlord shall be obligated to return to Tenant any Security Deposit funds previously delivered to Landlord in connection with this Lease. 
  
 D.    Early Termination of Proxim Sublease or AMAT Lease as to Building C. 
  
 (1)    In the event that the AMAT Lease
terminates as to Buildings A and B prior to September 1, 2003 and such termination is not due to a casualty event or condemnation action or a default by Tenant of any of its obligations under the Proxim Sublease, then this Lease shall commence with
respect to the portion of the Premises consisting of Building A and Building B and the Commencement Date shall be deemed to have occurred on the day immediately following such termination date; provided, however, the Termination Date of this Lease
shall not be affected by such early commencement of this Lease and shall remain August 31, 2009. In such event, the Rent with respect to the portion of the Premises consisting of Building A and Building B from such early Commencement Date through
August 31, 2003 shall be the rent payable by Tenant under the Proxim Sublease. Base Rent for Building A and Building B for the period commencing on September 1, 2003 shall be calculated in accordance with Section 2.A. In the event that the AMAT
Lease terminates as to Building C prior to September 1, 2003 and such termination is not due to a casualty event or condemnation action, then at Tenant’s election, in its sole discretion, this Lease shall commence with respect to the portion of
the Premises consisting of Building C and the Commencement Date shall be deemed to have occurred on the day immediately following such termination date; provided, however, the Termination Date of this Lease shall not be affected by such early
commencement of this Lease and shall remain August 31 , 2009. In such event, the Base Rent with respect to the portion of the Premises consisting of Building C from such early Commencement Date through August 31, 2003 shall be equal to the total
square footage of Building C times the monthly Base Rent per 

  

 3 

 
square foot payable by Tenant under the Proxim Sublease (including all increases contained therein). For the period commencing September 1, 2003 and for the
remainder of the Term, the monthly Base Rent for Building C shall be determined in accordance with Section 2.A. Notwithstanding the foregoing, if Landlord fails to deliver possession of the portion of the Premises consisting of Building C to Tenant
on or before such early Commencement Date vacant and otherwise in the condition required hereunder for any reason, then (i) this Lease shall not be void or voidable by either party, (ii) Landlord shall not be liable to Tenant for any loss or damage
resulting therefrom, and (iii) the early Commencement Date with respect to the portion of the Premises consisting of Building C shall be revised to mean the date on which Landlord delivers possession of the Premises consisting of Building C to
Tenant vacant and otherwise in the condition required hereunder and the Termination Date shall remain unchanged. Notwithstanding the foregoing, any early commencement of this Lease shall be conditioned upon Tenant’s satisfaction prior to the
early Commencement Date of the tests described in clauses (a) and (b) of Section l.C(l). In the event Tenant shall fail to satisfy such tests then, subject to Tenant’s right to post the Additional Security Deposit within thirty (30) days of
Landlord’s termination notice, as described in Section 1.C(1), Landlord shall have the right to terminate this Lease and thereafter neither party shall have any further rights or obligations hereunder, except that Landlord shall be obligated to
return to Tenant any Security Deposit finds previously delivered to Landlord in connection with this Lease. Notwithstanding the foregoing, in the event the Proxim Sublease or the AMAT Lease as to Building C is terminated due to a casualty event or
condemnation action, Tenant shall have the right to terminate this Lease with respect only to Building A and Building B in the case of such a termination of the Proxim Sublease or with respect only to Building C in the case of such a termination of
the AMAT Lease as to Building C, and thereafter neither party shall have any rights or obligations hereunder with respect to the Buildings so terminated, except that Landlord shall be obligated to return to Tenant any security deposit for such
Buildings previously delivered to Landlord in connection with this Lease. In the event that the Proxim Sublease is terminated due to a default on the part of the Landlord, Tenant shall have the right to terminate this Lease with respect only to
Building A and Building B, and thereafter neither party shall have any rights or obligations hereunder with respect to the Buildings so terminated, except that Landlord shall be obligated to return to Tenant any security deposit for such Buildings
previously delivered to Landlord in connection with this Lease 
  
 (2)    As provided in Section 1.C(2) above, in the event that the Proxim Sublease terminates as to the Premises prior to September 1, 2003 due to a default by Tenant of any of its obligations under
the Proxim Sublease, then such default shall automatically terminate this Lease and thereafter neither party shall have any further rights or obligations hereunder, except that Tenant shall remain liable for those obligations which were intended to
survive the termination of this Lease or the Proxim Sublease and Landlord shall be obligated to return to Tenant any Security Deposit funds previously delivered to Landlord in connection with this Lease.

 3.    CONDITION OF PREMISES. 
  
 A.    Condition of Premises. Landlord is leasing the portion of the Premises consisting of Building A and Building B to Tenant “as-is” without any obligation to
alter, remodel, improve, repair or decorate any part of the Premises or Project. Landlord represents that the roof, HVAC, plumbing and electrical systems for the portion of the Premises consisting of Building C shall be in good working order as of
the commencement Date and that Landlord promptly shall repair any problems with such systems in Building C that are noted in writing to Landlord within the thirty (30) day period immediately following the Building C Commencement Date. Landlord shall
deliver Building C to Tenant in broom clean condition on the Commencement Date. Landlord will use commercially reasonable efforts to enforce, with respect to Building C only, the surrender provision set forth in Section 15 of the AMAT Lease, and, as
a condition to 

  

 11 

 
granting any approval required for any alterations or improvements to Building C under the AMAT Lease or the Vitria Sublease, Landlord shall require that
AMAT or Vitria, as the case may be, remove all specialty or custom-made improvements and alterations made to Building C (as opposed to general office improvements and alterations) at the end of the respective lease term. Except as set forth in the
immediately preceding three sentences, Landlord makes no representations or warranties of any kind in connection with this Lease. 
  
 B.    Tenant’s Possession. As a result of the Proxim Sublease, Tenant shall be occupying the portion of the
Premises consisting of Building A and Building B for the period immediately preceding the Commencement Date. Therefore, Tenant hereby covenants and agrees to keep such portion of the Premises, other than the elevators which are located in Building A
and Building B and other items which are Landlord’s responsibility under the AMAT Lease, in good order, repair and condition throughout the term of the Proxim Sublease, subject to reasonable and normal wear and tear, casualty and condemnation.

  
 4.    SERVICES AND UTILITIES. As of
the Commencement Date, Tenant shall promptly pay, as the same become due, all charges for water, gas, electricity, telephone, sewer service, waste pick-up and any other utilities, materials and services furnished directly to or used by Tenant on or
about the Premises during the Term, including without limitation, (i) meter, use and/or connection fees, hook-up fees, or standby fees (excluding any connection fees or hook-up fees which relate to making the existing electrical, gas, water and
sewer service available to the Premises as of the Commencement Date), and (ii) penalties for discontinued interrupted service. If any utility service is not separately metered to the Premises, then Tenant shall pay its pro rata share of the cost of
such utility service with all others served by the service not separately metered. However, if Landlord reasonably determines that Tenant is using a disproportionate amount of any utility service not separately metered, then Landlord at its election
may (i) periodically charge Tenant, as Additional Rent, a sum equal to Landlord’s reasonable estimate of the cost of Tenant’s excess use of such utility service, or (ii) install, at Tenant’s expense, a separate meter to measure the
utility service supplied to the Premises. Any interruption or cessation of utilities resulting from any causes, including any entry for repairs pursuant to this Lease, and any renovation, redecoration or rehabilitation of any area of the Project
shall not render Landlord liable for damages to either person or property or for interruption or loss to Tenant’s business, nor be construed as an eviction of Tenant, nor work an abatement of any portion of Rent, nor relieve Tenant from
fulfillment of any covenant or agreement hereof; provided, however, in the event that Landlord’s negligent acts or omissions causes an interruption of the Project services causes the Premises to be untenantable for a period of at least ten (10)
consecutive business days, monthly Rent shall be thereafter abated proportionately. 
  
 5.    ALTERATIONS. 
  
 A.    Landlord’s Consent and Conditions. Tenant shall not make any improvements or alterations to the Premises (the “Work”) without in each instance submitting plans and specifications
for the Work to Landlord and obtaining Landlord’s prior written consent which shall not be unreasonably withheld, unless (a) the cost thereof is less than $25,000 per Building per occurrence, (b) such work does not impact the base structural
components or systems of the Building, (c) such Work will not impact any other tenant’s premises, and (d) such Work is not visible from outside the Premises. Provided that Landlord receives all necessary information and 

  

 12 

 
plans from Tenant, Landlord agrees to respond to Tenant’s request for Landlord’s prior written consent to such alterations within ten (10) business
days. However, even if Landlord’s prior written consent is not required Tenant shall provide Landlord with prior written notice at least five (5) days in advance of commencing the Work so that Landlord may take appropriate actions (e.g., notify
other tenants in the Project, post and record notices of nonresponsibility or other notices deemed by Landlord to be appropriate, request and review applicable insurance certificates) before the commencement of such Work. Tenant shall pay
Landlord’s actual out-of- pocket costs-incurred for reviewing of all of the plans and all other items submitted by Tenant. Landlord will be deemed to be acting reasonably in withholding its consent for any Work which (a) impacts the base
structural components or systems of the Building, and/or (b) impacts any other tenant’s premises. 
  
 As part of the Work, Landlord agrees that Tenant shall be entitled to construct exterior equipment pads located outside each Building leased by Tenant
hereunder and one or more exterior chemical storage facilities, provided that Tenant shall first submit to Landlord the proposed plans for such Work and obtain Landlord’s written approval of such plans prior to commencing such Work (whether
such Work is performed by Tenant during the term of this Lease or during the term of the Proxim Sublease). Landlord reserves the right to require Tenant, at its sole cost and expense, to remove such exterior Work upon termination or expiration of
this Lease. Tenant agrees and acknowledges that any parking spaces which may be taken by Tenant in connection with the construction and installation of such pads shall be deducted from Tenant’s parking spaces as set forth in Item 13 of the
Schedule. 
  
 Tenant shall pay for the cost of all Work, including
the cost of any and all approvals, permits, fees and other charges which may be required as a condition of performing such Work. Upon completion all Work shall become the property of Landlord, except for Tenant’s trade fixtures and those items
which Landlord requires Tenant to remove at Tenant’s cost at the termination of the Lease pursuant to Section 5E. Notwithstanding anything to the contrary herein, the parties acknowledge and agree that Tenant’s anechoic chamber shall
remain Tenant’s property and be treated herein as a trade fixture, which shall be removed (and any damage caused thereby shall be repaired) at Tenant’s sole cost and expense upon the expiration or termination of this Lease. 
  
 The following requirements shall apply to all Work: 
  
 (1)    Prior to commencement, Tenant
shall furnish to Landlord building permits, certificates of insurance satisfactory to Landlord, and, at Landlord’s reasonable request, security for payment of all costs. 
  
 (2)    Tenant shall perform all Work so as to maintain peace and harmony among other
contractors serving the Project and shall avoid interference with other work to be performed or services to be rendered in the Project. 
  
 (3)    The Work shall be performed in a good and workmanlike manner, meeting the standard for construction and quality
of materials in the Building, and shall comply with all insurance requirements and all applicable government laws, ordinances and regulations (“Governmental Requirements”). 
  

 13 

 (4)    Tenant shall perform all Work so as to minimize or prevent
disruption to other tenants, and Tenant shall comply with all reasonable requests of Landlord in response to complaints from other tenants. 
  
 (5)    Tenant shall perform all Work in compliance with any “Policies, Rules and Procedures for Construction
Projects” which may be in effect at the time the Work is performed. 
  
 (6)    Tenant shall permit Landlord to observe all Work. If Tenant requests that Landlord manage any construction Work, then Landlord reserves the right to charge a supervisory fee not to exceed
three percent (3%) of the labor, material, and all other costs of the Work. 
  
 (7)    Upon completion, Tenant shall furnish Landlord with contractor’s affidavits and full and final statutory waivers of liens covering all labor and materials, as-built plans and
specifications, and all other close-out documentation related to the Work reasonably requested by Landlord, including any other information required under any “Policies, Rules and Procedures for Construction Projects” which may be
in effect at such time. 
  
 B.    Damage to Systems. If any part of the mechanical, electrical or other systems in the Premises (e.g., HVAC, life safety or automatic fire extinguisher/sprinkler system) shall be damaged during the
performance of the Work, Tenant shall promptly notify Landlord, and Landlord shall repair such damage at Tenant’s expense. Landlord may also at any reasonable time make any repairs or alterations which Landlord deems necessary for the safety or
protection of the Project, or which Landlord is required to make by any court or pursuant to any Governmental Requirement. The cost of any repairs made by Landlord on account of Tenant’s default, or on account of the misuse or neglect by Tenant
or its invitees, contractors or agents anywhere in the Project, shall become Additional Rent payable by Tenant on demand. 
  
 C.    No Liens. Tenant has no authority to cause or permit any lien or encumbrance of any kind to affect Landlords
interest in the Project; any such lien or encumbrance shall attach to Tenant’s interest only. If any mechanic’s lien shall be filed or claim of lien made for work or materials furnished to Tenant, then Tenant shall at its expense within
ten (10) days thereafter either discharge or contest the lien or claim. If Tenant contests the lien or claim, then Tenant shall (i) within such ten (10) day period, provide Landlord adequate security for the lien or claim, (ii) contest the lien or
claim in good faith by appropriate proceedings that operate to stay its enforcement, and (iii) pay promptly any final adverse judgment entered in any such proceeding. If Tenant does not comply with these requirements, Landlord may discharge the lien
or claim, and the amount paid, as well as attorneys’ fees and other expenses incurred by Landlord. shall become Additional Rent payable by Tenant on demand. 
  
 D.    Ownership of Improvements. All Work as defined in this Section 5, hardware,
equipment, machinery and all other improvements and all fixtures except trade fixtures, constructed in the Premises by either Landlord or Tenant: (i) shall become Landlord’s property upon installation without compensation to Tenant, unless

 14 

 
(b) be removed in accordance with Subsection 5E below (unless Landlord at the time it gives its consent to the performance of such construction Work
expressly waives in writing the right to require such removal). Notwithstanding the foregoing, upon the expiration or termination of this Lease Tenant shall remove at its sole cost and expense any alterations and improvements, including, without
limitation, hardware, equipment, machinery and all other improvements and all fixtures installed in or made to the Premises during the term of the Proxim Sublease or the Vitria Sublease if directed in writing to do so by Landlord whether or not
Landlord’s consent to such alteration or improvement was granted or required (unless Landlord at the time it gives its consent to the performance of such construction Work expressly waives in writing the right to require such removal).

  
 E.    Removal upon
Termination. Upon the termination of this Lease or Tenant’s right of possession Tenant shall remove from the Premises and Project its trade fixtures, furniture, moveable equipment and other personal property, any improvements which Landlord
elects (pursuant to Section 5D) shall be removed by Tenant, and any improvements to any portion of the Project other than the Premises. If Tenant does not timely remove such property, then Tenant shall be conclusively presumed to have, at
Landlord’s election (i) conveyed such property to Landlord without compensation or (ii) abandoned such property., and Landlord may dispose of or store any part thereof in any manner at Tenant’s sole cost, without waiving Landlord’s
right. to claim from Tenant all expenses arising out of Tenant’s failure to remove the property, and without liability to Tenant or any other person. Landlord shall have no duty to be a bailee of any such personal property. If Landlord elects

or be responsible for any alterations, structural or otherwise. required to be made to the Building or the Premises under such laws. 
  

 15 

 B.    Signs. Tenant shall not place on any portion of the Premises any
sign, placard, lettering, banner, displays or other advertising or communicative material which is visible from the exterior of the Building without the prior written approval of Landlord. Landlord hereby agrees that so long as Tenant leases and

Date, including the repair of any damage caused to the Building and/or Project upon during such removal. 
  
 C.    Parking. Tenant shall have the non-exclusive right to park in the Project’s unassigned parking facilities in
common with other tenants of the Project upon terms and conditions, as may from time to time be established by Landlord. Tenant agrees not to overburden the parking facilities (i.e., use more than its pro rata share of the unallocated parking stalls
available for the Project) and agrees to cooperate with Landlord and other tenants in the Project in the use of the parking facilities. Landlord reserves the right in its discretion to determine whether the parking facilities are becoming crowded
and to allocate and assign parking spaces among Tenant and the other tenants in the Project. Landlord shall not be liable to Tenant, nor shall this Lease be affected, if any parking is impaired by moratorium, initiative, referendum, law, ordinance,
regulation or order passed, issued or made by any governmental or quasi-governmental body. In addition, Landlord reserves the right to charge Tenant the portion that Landlord deems allocable to Tenant of any charges (e.g., fees or taxes) imposed by

discretion. Notwithstanding the foregoing, during the Term, Tenant shall have the exclusive right at its sole cost to install, maintain, and from time to time replace radio frequency antennae and/or satellite dishes on the roof of the Building with
necessary related cabling and wiring connecting it to the Premises (such antennae, dishes, cabling and wiring being collectively referred to herein as the “Dish Equipment”) for purposes of facilitating wireless communications of Tenant to

(including the requirement to relocate such Dish Equipment), (iii) the conditions of any bond or warranty maintained by Landlord on the roof; and (C) the Dish Equipment shall not interfere,. electronically or otherwise, with the equipment,
facilities, use or operations of Landlord or of other preexisting (as of the date of the installation of such Dish Equipment) licensees or tenants of Landlord. Tenant shall use commercially reasonable efforts to coordinate with other licensees or
tenants of Landlord to avoid interference by the Dish Equipment with any later-installed antennae, dish equipment and wireless communications of such other parties. Landlord may supervise any roof penetration. In no event shall Landlord’s
approval of plans for the Dish Equipment or supervision of roof penetration be deemed a representation that the Dish Equipment will not cause, or be subject to, interference or that such plans will comply with Governmental Requirements, future
requirements of Landlord, or the conditions of any bond or warranty maintained by Landlord on the roof. Tenant shall repair any damage to the Building (including the roof) caused by the installation, maintenance, replacement, operation, use or

Landlord, Landlord shall have the right to relocate the Dish Equipment at Tenant’s sole cost. Tenant shall protect, defend, indemnify and hold harmless Landlord from and against claims, damages, liabilities, costs and expenses of every kind and
nature, including attorneys’ fees, incurred by or asserted against Landlord arising out of the installation, maintenance, replacement, operation, use or removal of the Dish Equipment (including the reasonable costs and expenses of
Landlord’s review of any plans for the Dish Equipment and the installation thereof). Notwithstanding anything to the contrary herein, Tenant shall have the exclusive right to use the roof for the installation, operation and maintenance of Dish
Equipment on each Building and Landlord shall not permit any other Dish Equipment to be installed on the roof so long as Tenant continues to lease 100% of such Building.

Requirements applying to its use of the Premises. Tenant shall also comply with all reasonable rules for the Project which may be established and amended from time to time by Landlord. The present rules and regulations are contained in Exhibit
B. Failure by another tenant to comply with the rules or failure by Landlord to enforce them shall not relieve Tenant of its obligation to comply with the rules or make Landlord responsible to Tenant in any way. Landlord shall use reasonable
efforts to apply the rules and regulations uniformly with respect to Tenant and any other tenants in the Project. In the event of alterations and repairs performed by Tenant, Tenant shall comply with the provisions of Section 5 of this Lease and any
applicable “Politics, Rules and Regulations for Construction Projects” which may be established by Landlord and in effect at the time.

areas of the Project. For purposes of this Lease, the common areas of the Project shall mean those areas outside of the Buildings which are for the benefit of all of the tenants in the Project (e.g., the landscape and parking areas, lighting,
sidewalks, driveways and the utility pipes, conduits and Hues which rim from the street to each Building and between each of the Buildings). The costs incurred by Landlord to perform the foregoing obligations to the extent they are deemed
“Operating Costs” (as defined in Section 2C) shall be passed through to Tenant and any other tenants in the Project, except that any damage to any of the foregoing caused by the negligence or willful acts or omissions of Tenant or of
Tenant’s agents, employees, subtenants, licensees or invitees, or by reason of the failure of Tenant to perform or comply with any term of this Lease, or caused by Tenant or Tenants agents, employees or contractors during the performance of any
work shall be repaired by Landlord, solely at Tenant’s expense, or at Landlord’s election, such repairs shall be made by Tenant, at Tenant’s expense, with contractors approved by Landlord. It is an express condition precedent to all
Landlord’s repair and maintenance obligations hereunder that Tenant shall have Landlord notification of the need for any repairs or maintenance; provided that any notification shall not affect Landlord’s obligation to perform routine
periodic maintenance (e.g., landscape maintenance) during the Lease Term. Tenant waives the provisions of Sections 1941 and 1942 of the California Civil Code and any similar or successor law regarding Tenants right to make repairs and deduct: the

roof membrane and the common areas of the Project and shall use reasonable efforts (other than the commencement of any litigation) to enforce such warranties to the extent the same may serve to reduce Tenant’s obligation to reimburse Landlord
for costs and expenses related thereto. Landlord shall use commercially reasonable efforts to enforce the terms of such warranties. In the event Tenant notifies Landlord in writing of an item needing immediate repair and there is no dispute
concerning the need for such repair, the scope of the repair or that Landlord is the party responsible for such repair, then Landlord shall commence and complete such repair within the responsible within fifteen (15) day period following
Landlord’s receipt of Tenant’s repair notice, unless the nature of the repair is such that more than fifteen (15) days is required to complete such repair in which case Landlord shall commence the repair within such fifteen (15) day period
and thereafter diligently prosecute the same to completion. In the event Landlord fails to dispute or commence the repair within such fifteen (15) day period, then Tenant shall have the right, but not the obligation, to cause the repair of such item
and to submit an invoice to Landlord for the reasonable out-of-pocket costs incurred by Tenant for the same (including reasonable supporting documentation for the same), and Landlord shall pay such amount to Tenant within thirty (30) days of receipt
of Tenant’s invoice and related documentation for such work. 
  
 B.    Tenant’s Obligations. Tenant shall at all times and at its own expense clean, keep and maintain in good order, condition and repair every part of the Premises (including Tenant’s 

 

 18 

 
trade fixtures and personal property) which is not within Landlords obligation pursuant to Section 8A. Tenant’s repair and maintenance obligations shall
include, all plumbing and sewage facilities within the Premises, fixtures, interior walls and ceiling, floors, windows (including repairing, resealing, cleaning and replacing, as necessary, of interior and exterior windows), doors, entrances, plate
glass, showcases, skylights, all electrical facilities and equipment, including lighting fixtures, lamps, fans and any exhaust equipment and systems, elevators, electrical motors and all other appliances and equipment of every kind and nature

bimonthly or monthly service in accordance with manufacturer recommendations, which shall be subject to the reasonable prior written approval of Landlord and paid for by Tenant, and which shall provide for and include replacement of filters, oiling
and lubricating of machinery, parts replacement, adjustment of drive belts, oil changes and other preventive maintenance, including annual maintenance of duct work, interior unit drains and caulking at sheet metal, and recaulking of jacks and vents
on an annual basis. Tenant shall have the benefit of all warranties available to Landlord regarding the equipment in such HVAC systems. To the extent Tenant fails to perform such repairs or maintenance as required herein, Landlord may, following
notice thereof to Tenant (which notice may be oral) and the lapse of fifteen (15) days thereafter during which Tenant shall fail to commence and diligently pursue such repairs and maintenance (except in emergencies requiring, in Landlord’s
determination. immediate repair and/or maintenance, in which case no notice or cure period shall apply), elect to perform all repairs and maintenance itself, at Tenant’s expense, to the Building’s mechanical, electrical or other systems in
the Premises (e.g., HVAC, life safety and automatic fire extinguisher/sprinkler systems). Landlord may also perform any maintenance or repairs itself, at Tenant’s expense, to the extent Tenant fails to perform such maintenance or repairs as
required herein. 
  
 9.    WAIVER OF CLAIMS:
INDEMNIFICATION; INSURANCE. 
  
 A.    Waiver of Claims. To the extent permitted by law, Tenant waives any claims it may have against Landlord or its officers, directors, employees or agents for business interruption or damage to property

agents for loss of rents or damage to property sustained by Landlord as the result of any act or omission of Tenant, its agents, contractors, employees or invitees. Landlord and Tenant hereby release each other and their respective agents,
employees, successors, assignees and subtenants from all liability for damage to the Premises that is caused by or results from a risk which is actually insured against under property insurance or required to be insured against hereunder, without

Premises to tenantability, using standard working methods without the payment of overtime and other premiums. If the time needed exceeds twelve (12) months from the beginning of the restoration, or two (2) months therefrom if the restoration would
begin during the last twelve (12) months of the Lease, then in the case of damage to the entire Premises, either Landlord or Tenant may terminate this Lease, and in the case of damage to an individual Building, either Landlord or Tenant may
terminate this Lease as to such Building, by notice to the other party within ten (10) days after the notifying party’s receipt of the architect’s certificate. If sufficient 

  

 21 

 
insurance proceeds will not be available to Landlord to cover the cost of any restoration to the Building or the Premises because (i) the casualty event was
not required to be insured against pursuant to the terms of this Lease and was not actually insured against, (ii) the financial inability of Landlord’s insurance carrier to make such proceeds available to Landlord, or (iii) Landlord’s
mortgagee, if any, has applied such proceeds to the indebtedness secured by such mortgagee and Landlord does not commence restoration within one hundred eighty (180) days of the damage, then in the case of damage to the entire Premises Landlord may
terminate this Lease or in the case of damage to an individual Building Landlord may terminate this Lease as to such Building, in each case by written notice to Tenant. Any termination pursuant to this Section 10.4 shall be effective thirty (30)
days from the date of such termination notice and Rent shall be paid by Tenant to that date, with an abatement for any portion of the space which has been untenantable after the casualty. Notwithstanding any of the foregoing, Landlord shall not have
the right to terminate this Lease if the damage to the Premises is relatively minor (for example, if the repair or restoration would cost less than ten percent (10%) of the replacement cost of the Premises). 
  
 B.    Restoration. If a casualty causes
damage to the Building or the Premises but this Lease is not terminated for any reason, then subject to the rights of any mortgagees or ground lessors, Landlord shall obtain the applicable insurance proceeds and diligently restore the Building and
the Premises subject to current Governmental Requirements. Landlords obligation, should it elect or be obligated to repair or rebuild, shall be limited to the Building Shell (as defined in the AMAT Lease), and Tenant shall, at Tenant’s expense,
replace or fully repair its damaged improvements (including any tenant improvements constructed within the Building Shell), personal property and fixtures. Rent shall be abated on a per diem basis during the restoration for any portion of the
Premises which is untenantable. Tenant shall not be entitled to any compensation or damages from Landlord for loss of the use of the Premises, damage to Tenant’s personal property and trade fixtures or any inconvenience occasioned by such
damage, repair or restoration. Tenant hereby waives the provisions of Section 1932, Subdivision 2, and Section 1933, Subdivision 4, of the California Civil Code, and the provisions of any similar law hereinafter enacted. 
  
 11.    EMINENT DOMAIN. If a part of the Project is
taken by eminent domain or deed in lieu thereof which is so substantial that the entire Premises cannot reasonably be used by Tenant for the operation of its business. then either party may terminate this Lease effective as of the date of the
taking. If a part of the Project is taken by eminent domain or deed in lieu thereof which is so substantial that an individual Building cannot reasonably be used by Tenant for the operation of its business, then either party may terminate this Lease
as to such Building effective as of the date of the taking. Rent shall abate from the date of the taking in proportion to any part of the Premises taken. If there is a temporary taking of a part of the Project which is so substantial that the
Premises cannot reasonably be used by Tenant for the operation of its business, then Rent shall abate from the date of the taking in proportion to any part of the Premises taken. The entire award for a taking of any kind shall be paid to Landlord,
and Tenant shall have no right to share in the award except for the portion of the award expressly based on the value of improvements to the Premises paid for by Tenant, provided that (i) nothing contained herein shall be deemed to give Landlord any
interest in or require Tenant to assign to Landlord any separate award made to Tenant for the taking of Tenant’s personal property, and trade fixtures or its relocation costs, and (ii) in the event of a temporary taking in which there was no
Rent abatement under this Lease, 

  

 22 

 
then Tenant shall be entitled to any portion of such award which was intended to compensate Landlord for lost Rent for the Premises during the period of the
temporary taking. All obligations accrued to the date of the taking shall be performed by the party liable to perform such obligation as set forth herein. Tenant may pursue a separate award for its trade fixtures and moving expenses in connection
with the taking, but only if such recovery does not reduce the award payable to Landlord. 
  
 12.    RIGHTS RESERVED TO LANDLORD. Landlord may exercise at any time any of the following rights respecting the operation of the Project without liability to Tenant of any
kind: 
  
 A.    Name. To change
the name of all or any of the Buildings or the Project; provided, however, that so long as Tenant leases and occupies more than fifty percent (50%) of any Building, then Landlord may not change the name of such Building without Tenant’s prior

 F.    Preparation for Reoccupancy. To
decorate, remodel, repair, alter or otherwise prepare the Premises for reoccupancy at any time after Tenant abandons the Premises, without relieving Tenant of any obligation to pay Rent.

Premises. 
  

 23 

 I.    Use of Lockbox. To designate a lockbox collection agent for
collections of amounts due Landlord. In that case, the date of payment of Rent or other sums shall be the date of the agent’s receipt of such payment or the date of actual collection if payment is made in the form of a negotiable instrument

any such repairs or alterations during ordinary business hours, except that Tenant may require any work in the Premises to be done after business hours if Tenant pays Landlord for overtime and any other additional expenses incurred. Landlord may do
or permit any work on any nearby building, land, street, alley or way. 
  
 K.    Landlord’s Agents. If Tenant is in default under this Lease, possession of Tenant’s funds or negotiation of Tenant’s negotiable instrument by any of Landlord’s agents shall not
waive any breach by Tenant or any remedies of Landlord under this Lease. 
  
 L.    CC&Rs. At any time when Tenant is not occupying all of the Buildings in the Project, Landlord may promulgate and record a set of CC&Rs which will govern the access,
parking, design, signage and other rights of the tenants in the Project, so long as such CC&Rs do not impose any new payment obligation on Tenant (i.e., a dues requirement) or require Tenant to modify any of the then existing improvements.

  
 13.    TENANT’S DEFAULT. Any of
the following shall constitute a default by Tenant: 
  
 A.    Rent Default. Tenant fails to pay any Rent within five (5) days after notice that such payment was not paid when due, provided that Tenant acknowledges that such notice shall be in lieu of and not in
addition to any notice required to be given by Landlord to commence an unlawful detainer action (or similar eviction proceeding) under the then applicable law; 
  

B.    Assignment/Sublease or Hazardous Substances Default. Tenant defaults in its obligations under Section 18

 C.    Other Performance Default. Tenant fails to perform any other obligation to Landlord under this Lease. and this failure continues for thirty (30) days after written notice from Landlord, except that if

to one hundred twenty (120) days, or such lesser period as is reasonably necessary to complete the cure; 
  
 D.    Credit Default. One of the following credit defaults occurs: 
  

 24 

 (1)    Tenant commences any proceeding under any law relating to
bankruptcy, insolvency, reorganization or relief of debts, or seeks appointment of a receiver, trustee, custodian or other similar official for the Tenant or for any substantial part of its property, or any such proceeding is commenced against
Tenant and either remains undismissed for a period of sixty (60) days or results in the entry of an order for relief against Tenant which is not fully stayed within seven (7) days after entry; 
  
 (2)    Tenant becomes insolvent or
bankrupt, does not generally pay its debts as they become due, or admits in writing its inability to pay its debts, or makes a general assignment for the benefit of creditors; 
  
 (3)    Any third party obtains a levy or attachment under process of law against
Tenant’s leasehold interest; and 
  
 E.    Abandonment Default. Tenant abandons the Premises. 
  
 14.    LANDLORD REMEDIES. Upon a default, Landlord shall have the following remedies, in addition to all other rights and remedies provided by law or otherwise provided in this
Lease, to which Landlord may resort cumulatively or in the alternative: 
  
 A.    Termination of Lease or Possession. If Tenant defaults, Landlord may elect by notice to Tenant either to terminate this Lease or to terminate Tenant’s possession of the Premises without
terminating this Lease. In either case, Tenant shall immediately vacate the Premises and deliver possession to Landlord, and Landlord may repossess the Premises and may, at Tenant’s sole cost, remove any of Tenant’s signs and any of its
other property, without relinquishing its right to receive Rent or any other right against Tenant. In the latter case, this Lease shall continue in full force and effect as long as Landlord does not terminate this Lease, and Landlord shall have the
right to collect Rent when due. 
  
 B.    Possession Termination Damages. If Landlord elects to terminate Tenant’s possession without terminating this Lease and Landlord takes possession of the Premises itself, then Landlord may relet
for Tenant’s account all or any portion of the Premises for such rent, length of time and other terms as Landlord in its sole discretion shall determine, without any obligation to do so prior to renting other vacant areas in the Building.
Tenant shall be liable immediately to Landlord for all costs Landlord incurs in reletting the Premises or any part thereof, including, without limitation, broker’s commissions, expenses of cleaning and redecorating the Premises required by the
reletting and like costs. Tenant shall pay to Landlord the Rent and other sums due under this Lease on the date the Rent is due, less the rent and other sums received by Landlord from any releasing of the Premises. No act by Landlord other than
giving written notice to Tenant shall terminate this Lease. Acts of maintenance, efforts to relet the Premises or the appointment of a receiver on Landlord’s initiative to protect Landlord’s interest under this Lease shall not constitute a
termination of Tenant’s right to possession. 
  
 C.    Lease Termination Damages. If Landlord elects to terminate this Lease, then this Lease shall terminate on the date for termination set forth in such notice. Tenant shall immediately vacate the
Premises and deliver possession to Landlord and Landlord may repossess the Premises and may, at Tenant’s sole cost, remove any of Tenant’s signs and any of its other 
  

 25 

 
property, without relinquishing its right to receive Rent or any other right against Tenant. On termination, Landlord has the right to recover from Tenant as
damages: 
  
 (1)    The worth
at the time of award of unpaid Rent and other sums due and payable which had been earned at the time of termination; plus 
 (2)    The worth at the time of award of the amount by which the unpaid Rent and other sums due and payable which after termination until the time of award exceeds the amount of such Rent loss that Tenant proves could
have been reasonably avoided; plus 
 (3)    The worth at the time of award of the amount by which the
unpaid Rent and other sums due and payable for the balance of the Term after the time of award exceeds the amount of such Rent loss that Tenant proves could be reasonably avoided; plus 
 (4)    Any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s
failure to perform Tenant’s obligations under this Lease, or which, in the ordinary course of things, would be likely to result therefrom, including, without limitation, any costs or expenses incurred by Landlord: (i) in retaking possession of
the Premises; (ii) in maintaining, repairing, preserving, restoring, replacing, cleaning, altering or rehabilitating the Premises or any portion thereof, including such acts for reletting to a new tenant or tenants; and (iii) for leasing commissions
and other costs necessary or appropriate to relet the Premises (to the extent allocable to the remainder of the Term); plus 
 (5)    At Landlord’s election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by the laws of the State of California. 
  
 The “worth at the time of award” of the amounts referred to in
Sections 14C(1) and 14C(2) is computed by allowing interest at the maximum rate permitted by law on the unpaid rent and other sums due and payable from the termination date through the date of award. The “worth at the time of award” of the
amount referred to in Section 14C(3) is computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one percent (1%). Tenant waives redemption or relief from forfeiture under
California Code of Civil Procedure Sections 1174 and 1179, or under any other present or future law, in the event Tenant is evicted or Landlord takes possession of the Premises by reason of any default of Tenant hereunder. 
  
 D.    Landlord’s Remedies Cumulative.
All of Landlord’s remedies under this Lease shall be in addition to all other remedies Landlord may have at law or in equity, including without limitation, the remedy described in California Civil Code Section 1951.4 (i.e., Landlord may
continue the Lease in effect after Tenant’s breach and abandonment and recover as rent as it becomes due if Tenant has the right to sublet or assign the Lease, subject to reasonable limitations). Waiver by Landlord of any breach of any
obligation by Tenant shall be effective only if it is in writing, and shall not be deemed a waiver of any other breach, or any subsequent breach of the same obligation. Landlord’s acceptance of payment by Tenant shall not constitute a waiver of
any breach by Tenant, and if the acceptance occurs after Landlord’s notice to Tenant, or termination of this Lease or of Tenant’s right to possession, the acceptance shall not affect such notice or termination. Acceptance of payment by
Landlord after commencement of a legal 

  

 26 

 
proceeding or final judgment shall not affect such proceeding or judgment. Landlord may advance such monies and take such other actions for Tenant’s
account as reasonably may be required to cure or mitigate any default by Tenant. Tenant shall immediately reimburse Landlord for any such advance, and such sums shall bear interest at the default interest rate until paid. 
  
 E.    WAIVER OF TRIAL BY JURY. EACH PARTY
WAIVES TRIAL BY JURY IN THE EVENT OF ANY LEGAL PROCEEDING BROUGHT BY THE OTHER IN CONNECTION WITH THIS LEASE. EACH PARTY SHALL BRING ANY ACTION AGAINST THE OTHER IN A FEDERAL OR STATE COURT LOCATED IN CALIFORNIA, CONSENTS TO THE JURISDICTION OF SUCH
COURTS, AND WAIVES ANY RIGHT TO HAVE ANY PROCEEDING TRANSFERRED FROM SUCH COURTS ON THE GROUND OF IMPROPER VENUE OR INCONVENIENT FORUM CONNECTION WITH THIS LEASE.

to Section 5E, and restore the Premises to its condition prior to their installation. If Tenant fails to remove any alterations and/or Tenant’s personal property, and such failure continues after the termination of this Lease, Landlord may
retain or dispose of such property and all rights of Tenant with respect to it shall cease, or Landlord may place all or any portion of such property in public storage for Tenant’s account. Tenant shall be liable to Landlord for costs of
removal of any such alterations and Tenant’s personal property and storage and transportation costs of same, and the cost of repairing and restoring the Premises, together with interest at the Interest Rate from the date of expenditure by
Landlord. If the Premises are not so surrendered at the termination of this Lease, Tenant shall indemnify Landlord against all loss or liability, including attorneys’ fees and costs, resulting from delay by Tenant in so surrendering the
Premises. 
  
 16.    HOLDOVER. Tenant shall have
no right to holdover possession of the Premises after the expiration or termination of this Lease without Landlord’s prior written consent. which Landlord may withhold in its sole and absolute discretion. If, however, Tenant retains possession
of any part of the Premises after the Term, Tenant shall become a tenant at sufferance only, for the entire Premises upon all of the terms of this Lease as might be applicable to such tenancy, except that Tenant shall pay all of Base Rent at one
hundred fifty percent (150%) of the rate in effect immediately prior to such holdover, plus Operating Cost Share Rent and Tax Share Rent, computed on a monthly basis for each full or partial month Tenant remains in possession. Tenant shall also pay
Landlord all of Landlord’s direct and consequential damages resulting from 
  

 27 

 
Tenant’s holdover. No acceptance of Rent or other payments by Landlord under these holdover provisions shall operate as a waiver of Landlord’s
right to regain possession or any other of Landlord’s remedies. 
  
 17.    SUBORDINATION TO GROUND LEASES AND MORTGAGES. 
  
 A.    Subordination. This Lease shall be subordinate to any present or future ground lease or mortgage respecting the
Project, and any amendments to such ground lease or mortgage, at the election of the ground lessor or mortgagee as the case may be, effected by notice to Tenant in the manner provided in this Lease. The subordination shall be effective upon such
notice, but at the request of Landlord or ground lessor or mortgagee, Tenant shall within ten (10) days of the request, execute and deliver to the requesting party any reasonable documents provided to evidence the subordination of this Lease to such
ground lease or mortgage, provided such documents state that (i) so long as no default shall have occurred and be continuing beyond any applicable grace, cure or notice period under this Lease, Tenant’s use and possession of the Premises shall

mortgagee, or purchaser at a foreclosure sale shall thereby become the owner of the Project, Tenant shall attorn to such ground lessor or mortgagee or purchaser without any deduction or setoff by Tenant, and this Lease shall continue in effect as a

ground Lessor or mortgagee begins to cure within ten (10) days after such period and proceeds diligently to complete such cure, then ground lessor or mortgagee shall have such additional time as is necessary to complete such cure, including any time
necessary to obtain 
  

 28

party, the other party has committed no uncured defaults and has no offsets or claims. The certifying party may also be required to state the date of
commencement of payment of Rent, the Commencement Date, the Termination Date, the Base Rent, the current Operating Cost Share Rent and Tax Share Rent estimates, the status of any improvements required to be completed by Landlord, and the amount of
any security deposit. Failure to deliver such statement within the time required shall be conclusive evidence against the non-certifying party that this Lease, with any amendments identified by the requesting party, is in full force and effect, that
there are no uncured defaults by the requesting party, that not more than one month’s Rent has been paid in advance, that the amount of any security deposit is as set forth in the Lease, and that the non- certifying party has no claims or
offsets against the requesting party. 
  
 21.    FINANCIAL STATEMENTS. Within ten (10) days after Landlord’s written request therefore, Tenant shall deliver to Landlord copies of Tenant’s most recent publicly reported financial
statements. 
  
 22.    SECURITY DEPOSIT.
Tenant shall deposit with Landlord on the date Tenant executes and delivers this Lease to Landlord the cash sum set forth in the Schedule for the Initial Security Deposit. Notwithstanding the foregoing, during the period from the date of this Lease
to, but not including, the Commencement Date, the Initial Security Deposit may be in the form of a Letter of Credit (the “Initial Security Deposit Letter of Credit”) provided that any such Initial Security Deposit Letter of Credit shall
(i) be in the form of an unconditional and irrevocable letter of credit which is acceptable to Landlord, (ii) name Landlord as beneficiary, (iii) expressly allow Landlord to draw upon it (including partial withdrawals) at any time from time to time
by delivering to the issuer written certification that Landlord is entitled to draw thereunder as a result of Tenant’s default hereunder (beyond any applicable grace, notice or cure period), (iv) be drawable on an FDIC-insured financial
institution satisfactory to Landlord, (v) be redeemable in the State of California in one of the nine counties comprising the San Francisco-Oakland-San Jose area (the “Bay Area”), (vi) allow partial draws, and (vii) be transferable to any
successor to Landlord’s interest in this Lease at no cost to Landlord. On the Commencement Date, Tenant shall deliver to Landlord cash in the amount of the Initial Security Deposit, which amount shall then constitute the Initial Security
Deposit, and Landlord shall deliver to Tenant, or take other appropriate steps to cancel, the Initial Security Deposit Letter of Credit. In the event Tenant fails to deliver such cash on the Commencement Date to Landlord, Landlord may thereupon draw
on the Initial Security Deposit Letter of Credit. At all times prior to the Commencement Date, the amount drawable under the Initial Security Deposit Letter of Credit shall be equal or greater than the amount of the Initial Security Deposit. If
Tenant does not provide Landlord with a substitute Initial Security Deposit Letter of Credit complying with all of the requirements hereof at least thirty (30) days before the stated expiration date of the current Initial Security Deposit Letter of
Credit, then Landlord shall have the right to draw upon the current Initial Security Deposit Letter of Credit and hold the funds drawn as part of the Initial Security Deposit; provided, however, so long as no default (beyond any applicable grace,
notice or cure period) shall exist hereunder, Tenant may have an additional thirty (30) days following Landlord’s draw on the current Initial Security Deposit Letter of Credit in which to provide Landlord with a substitute Initial Security
Deposit Letter of Credit complying with each of the foregoing criteria, and upon such delivery Landlord shall return to Tenant an amount in cash (but without any interest thereon) equal to the lesser of the amount drawn under the current Initial
Security Deposit Letter of Credit or the face amount of the substitute Initial Security Deposit Letter of Credit. In the event Landlord notifies 

  

 31 

 Tenant in writing that the bank which issued the Initial Security Deposit Letter of Credit has become financially
unacceptable (e.g., the bank is under investigation by governmental authorities or has filed bankruptcy or reorganization proceedings), then Tenant shall have thirty (30) days to provide Landlord with a substitute Initial Security Deposit Letter of
Credit complying with all of the requirements hereof. The Initial Security Deposit and any Additional Security Deposit required to be deposited by Tenant pursuant to Section 1.C(1)) are collectively referred to herein as the “Security
Deposit”). The Security Deposit shall be held by Landlord during the Term as security for the performance of all of Tenant’s obligations hereunder. If Tenant defaults under this Lease, Landlord may apply all or any part of the Security
Deposit to the extent required for the payment of any Rent or other sum in default, the repair of any damage to the Premises caused by Tenant or the payment of any other amount which Landlord may spend or become obligated to spend by reason of
Tenant’s default or to compensate Landlord for any other loss or damage which Landlord may suffer by reason of Tenant’s default to the full extent permitted by law. To the extent any portion of the Security Deposit is used, Tenant shall
within five (5) days after demand from Landlord restore the deposit to its full amount. Landlord may keep the Security Deposit in its general funds and shall not be required to pay interest to Tenant on the deposit amount. Landlord shall return all
of the then-remaining Security Deposit to Tenant within thirty (30) days after the end of the Term. The Security Deposit shall not serve as an advance payment of Rent or a measure of Landlord’s damages for any default under this Lease.

  
 If Landlord transfers its interest in the Project or this
Lease, Landlord shall either (a) transfer the portion of the Security Deposit then held by Landlord to its transferee or (b) return to Tenant the portion of the Security Deposit then held by Landlord and remaining after the deductions permitted
herein. Upon such transfer to such transferee or return of the Security Deposit to Tenant, Landlord shall have no further obligation with respect to the Security Deposit, and Tenant’s right to the return of the Security Deposit shall apply
solely against Landlord’s transferee. 
  
 23.    FORCE MAJEURE. Neither Landlord or Tenant shall be in default under this Lease to the extent that party is unable to perform any of its obligations on account of any strike or labor problem,
equipment, material, supplies or energy shortages (i.e., such items cannot be obtained at normal costs within a reasonable time because of limited availability), governmental pre-emption or prescription, national emergency, or any other cause of any
kind beyond the reasonable control of the party required to act (provided that the foregoing shall not apply to any monetary obligation) (“Force Majeure”).

no obligation to provide Tenant with any tenant improvement allowance in connection with any Renewal Term, and (iii) any reference in the Lease to the “Term” of the Lease shall be deemed to include any Renewal Term and apply thereto,
unless it is expressly provided otherwise. Tenant shall have no additional extension options. 
  
 A.    The Base Rent during any Renewal Term shall be 100% of the then prevailing market rate for a comparable term commencing on the first day of the Term for tenants of comparable size and
creditworthiness for comparable space in the Building and other first class buildings of comparable age with similar facilities in the vicinity of the Building (the “Renewal Market Rate”). 
  
 (1)    Not sooner than nine (9) months
nor later than six (6) months prior to the Commencement Date, Landlord and Tenant shall commence negotiations to agree upon the Renewal Market Rate. If Landlord and Tenant are unable to reach agreement within twenty-one (21) days, then the Renewal
Market Rate shall be determined in accordance with Subsection (2) below. 
  
 (2)    If Landlord and Tenant are unable to reach agreement on the Renewal Market Rate within said twenty-one (21) day period, then within seven (7) days, Landlord and Tenant shall simultaneously
submit to each other in a sealed envelope its good faith estimate of the Renewal Market Rate. If the higher of such estimates is not more than one hundred five percent (105%) of the lower, then the Renewal Market Rate shall be the average of the two
amounts. Otherwise, the dispute shall be resolved by arbitration in accordance with Subsection (3) below. 
  
 (3)    Within seven (7) days after the exchange of estimates, the parties shall select an independent MAI appraiser
with at least five (5) years of experience in appraising similar space in the metropolitan area in which the Project is located (a “Qualified Appraiser”). If the parties cannot agree on a Qualified Appraiser, then within a second
period of seven (7) days, each shall select a Qualified Appraiser and within ten (10) days thereafter the two appointed Qualified Appraiser shall select a third Qualified Appraiser and the third Qualified Appraiser shall be the sole arbitrator. If
one party shall fail to select a Qualified Appraiser within the second seven (7) day period, then the Qualified Appraiser chosen by the other party shall be the sole arbitrator. The Qualified Appraiser, however selected, shall be a person who has
not previously acted in any capacity for either Landlord or Tenant (or any Tenant Affiliate, or any of 
  

 38 

 
their subsidiaries or related entities). All of the relevant information used by Landlord and Tenant to prepare their final offers shall be delivered to the
Qualified Appraiser. 
  
 (4)    Within twenty-one (21) days after submission of the relevant information to the Qualified Appraiser, the Qualified Appraiser shall determine the Renewal Market Rate provided in no event shall the Market Rate be
less than the lower of or more that the higher of the two final offers submitted by Landlord and Tenant. The arbitrator shall notify Landlord and Tenant of its decision, which shall be final and binding. If the Qualified Appraiser reasonably
believes that expert advice would materially assist him, then the Qualified Appraiser may retain one or more qualified persons to provide expert advice. Landlord and Tenant shall each bear one-half (1⁄2) of the fees of the Qualified Appraiser and
the expenses of the appraisal process, including the fees of any expert witnesses retained by the Qualified Appraiser. Notwithstanding the foregoing, each party shall pay the fees of its respective counsel and the fees of any witnesses called by
that party. 
  
 (5)    After
the Base Rent for the Renewal Tern has been established (whether by Landlord and Tenant or the Qualified Appraiser), Landlord and Tenant shall execute an amendment to reflect the new Base Rent and other terms and conditions which will apply during
the Renewal Term. 
  
 B.    To exercise
any option, Tenant must deliver a binding notice to Landlord not sooner than ten (10) months nor later than eight (8) months prior to the expiration of the initial Term of this Lease, or the then applicable Renewal Term, as the case may be.
Thereafter, the Renewal Market Rate for the particular Renewal Term shall be calculated pursuant to Subsection A above. Such calculations shall be final and shall not be recalculated at the actual commencement of such Renewal Term. If Tenant fails
to timely give its notice of exercise, Tenants will be deemed to have waived its option to extend. 
  
 [THE REMAINDER OF THIS PAGE HAS BEEN LEFT BLANK INTENTIONALLY]

that: (i) on the date that Tenant delivers its binding notice exercising an option to extend, Tenant is not in default under this Lease (after the expiration of any applicable notice and cure periods), and (ii) Tenant shall not have assigned the
Lease or sublet the entire portion of any Building for substantially the remainder of the Term (or, if applicable, the prior Renewal Term) to any party other than a Tenant Affiliate. For purposes of the foregoing, the term “substantially the
remainder of the Term” shall mean any sublease with an expiration date occurring during the last six (6) months of the Term. 
  
 IN WITNESS WHEREOF, the parties hereto have executed this Lease on the dates set forth below as of the Effective Date (subject to Section 1.C).
