 ARTICLE FOUR 
 OPERATING EXPENSES, RENT ADJUSTMENTS AND PAYMENTS 
  

	4.01	TENANT’S SHARE OF OPERATING EXPENSES 

  
 Tenant shall pay Tenant’s Share of Operating Expenses in the respective shares of the respective categories of Operating Expenses as set forth below. 
  
 (a) Tenant’s Project Share of Project Operating Expenses, which is the
percentage obtained by dividing the rentable square footage of the Premises for the building(s) in which the Premises is located by the rentable square footage of the Project and as of the date hereof equals the percentage set forth in Section
1.01(16); 
  
 (b) Tenant’s Building Share of Building
Operating Expenses, which is the percentage obtained by dividing the rentable square footage of the Premises respectively for each building in which the Premises is located by the total rentable square footage of such building and as of the date
hereof equals the percentage set forth in Section 1.01(16); 
  
 (c) Tenant’s Phase Share of Phase Operating Expenses, which is the percentage obtained by dividing the aggregate rentable square footage of the Premises located in Tenant’s Phase by the total rentable square footage of
Tenant’s Phase and as of the date hereof equals the percentage set forth in Section 1.01(16); 
  
 (d) Project Operating Expenses shall mean all Operating Expenses that are not included as Phase Operating Expenses (defined below) and that are not either
Building Operating Expenses or operating expenses directly and separately identifiable to the operation, maintenance or repair of any other building located in the Project, but Project Operating Expenses includes operating expenses allocable to any
areas of the Building or any other building during such time as such areas are made available by Landlord for the general common use or benefit of all tenants of the Project, and their employees and invitees, or the public, as such areas currently
exist and as they may be changed from time to time; 
  
 (e)
Building Operating Expenses shall mean Operating Expenses that are directly and separately identifiable to each building and only such building(s) in which the Premises or part thereof is located. Building(s) in which the Premises or any part
thereof are not located shall not be included in determining Building Operating Expenses; 
  
 (f) Phase Operating Expenses shall mean Operating Expenses that Landlord may allocate to a Phase as directly and separately identifiable to all buildings located in the Phase (including but not limited to the
Building) and may include Project Operating Expenses that are separately identifiable to a Phase; 
  
 (g) Landlord shall have the right to allocate a particular item or portion of Operating Expenses as any one of Project Operating Expenses, Building
Operating Expenses or Phase Operating Expenses; however, in no event shall any portion of Building Operating Expenses, Project Operating Expenses or Phase Operating Expenses be assessed or counted against Tenant more than once; and. 
  
 (h) Notwithstanding anything to the contrary contained in this Section 4.01,
as to each specific category of Operating Expense which one or more tenants of the Building either pays directly to third parties or specifically reimburses to Landlord (for example, separately contracted janitorial services or property taxes
directly reimbursed to Landlord), then, on a category by category basis, the amount of Operating Expenses for the affected period shall be adjusted as follows: (1) all such tenant payments with respect to such category of expense and all of
Landlord’s costs reimbursed thereby shall be excluded from Operating Expenses and Tenant’s Building Share, Tenant’s Phase Share or Tenant’s Project Share, as the case may be, for such category of Operating Expense shall be
adjusted by excluding the square footage of all such tenants, and (2) if Tenant pays or directly reimburses Landlord for such category of Operating Expense, such category of Operating Expense shall be excluded from the determination of Operating
Expenses for the purposes of this Lease. 
  

	4.02	RENT ADJUSTMENTS 

  
 Tenant shall pay to Landlord Rent Adjustments with respect to each Adjustment Year as follows: 
  
 (a) The Rent Adjustment Deposit shall be paid monthly during the Term with the payment of Monthly Base Rent, except the first installment which shall be
paid by Tenant to Landlord concurrently with execution of this Lease. The Rent Adjustment Deposit represents, on a monthly basis, Tenant’s Share of Landlord’s estimate of Operating Expenses, as described in Section 4.01, for the applicable
Adjustment Year (or portion thereof); and 
  
 (b) Any Rent
Adjustments due in excess of the Rent Adjustment Deposits in accordance with Section 4.03. 
  

 7 

	4.03	STATEMENT OF LANDLORD 

  
 Within one hundred twenty (120) days after the end of each calendar year or as soon thereafter as reasonably possible, Landlord will furnish Tenant a statement (“Landlord’s Statement”) showing the
following: 
  
 (a) Operating Expenses for the last Adjustment
Year showing in reasonable detail the actual Operating Expenses categorized among Project Operating Expenses, Building Operating Expenses and Phase Operating Expenses for such period and Tenant’s Share of each as described in Section 4.01
above; 
  
 (b) The amount of Rent Adjustments due Landlord for the
last Adjustment Year, less credit for Rent Adjustment Deposits paid, if any; and 
  
 (c) Any change in the Rent Adjustment Deposit due monthly in the current Adjustment Year, including the amount or revised amount due for months preceding any such change pursuant to Landlord’s Statement.

  
 Tenant shall pay to Landlord within thirty (30) days after receipt of such
statement any amounts for Rent Adjustments then due in accordance with Landlord’s Statement. Any amounts due from Landlord to Tenant pursuant to this Section shall be credited to the Rent Adjustment Deposit next coming due, or refunded to
Tenant if the Term has already expired provided Tenant is not in default hereunder. No interest or penalties shall accrue on any amounts which Landlord is obligated to credit or refund to Tenant by reason of this Section 4.03. Landlord’s
failure to deliver Landlord’s Statement or to compute the amount of the Rent Adjustments shall not constitute a waiver by Landlord of its right to deliver such items nor constitute a waiver or release of Tenant’s obligations to pay such
amounts. The Rent Adjustment Deposit shall be credited against Rent Adjustments due for the applicable Adjustment Year. During the last complete calendar year or during any partial calendar year in which the Lease terminates, Landlord may include in
the Rent Adjustment Deposit its estimate of Rent Adjustments which may not be finally determined until after the termination of this Lease. Tenant’s obligation to pay Rent Adjustments survives the expiration or termination of the Lease.
Notwithstanding the foregoing, in no event shall the sum of Monthly Base Rent and the Rent Adjustments be less than the Monthly Base Rent payable. 
  

	4.04	BOOKS AND RECORDS 

  
 Landlord shall maintain books and records showing Operating Expenses and Taxes in accordance with sound accounting and management practices, consistently applied. The Tenant or its representative shall have the right,
for a period of ninety (90) days following the date upon which Landlord’s Statement is delivered to Tenant, to examine the Landlord’s books and records with respect to the items in the foregoing statement of Operating Expenses and Taxes
during normal business hours, upon written notice, delivered at least three (3) business days in advance. If Tenant does not object in writing to Landlord’s Statement within ninety (90) days of Tenant’s receipt thereof, specifying the
nature of the item in dispute and the reasons therefor, then Landlord’s Statement shall be considered final and accepted by Tenant. Any amount due to the Landlord as shown on Landlord’s Statement, whether or not disputed by Tenant as
provided herein shall be paid by Tenant when due as provided above, without prejudice to any such written exception. 
  

	4.05	TENANT OR LEASE SPECIFIC TAXES 

  
 In addition to Monthly Base Rent, Rent Adjustments, Rent Adjustment Deposits and other charges to be paid by Tenant, Tenant shall pay to Landlord, upon demand, any and
all taxes payable by Landlord (other than federal or state inheritance, general income, gift or estate taxes) whether or not now customary or within the contemplation of the parties hereto: (a) upon, allocable to, or measured by the Rent payable
hereunder, including any gross receipts tax or excise tax levied by any governmental or taxing body with respect to the receipt of such rent; or (b) upon or with respect to the possession, leasing, operation, management, maintenance, alteration,
repair, use or occupancy by Tenant of the Premises or any portion thereof; or (c) upon the measured value of Tenant’s personal property or trade fixtures located in the Premises or in any storeroom or any other place in the Premises or the
Property, or the areas used in connection with the operation of the Property, it being the intention of Landlord and Tenant that, to the extent possible, Tenant shall cause such taxes on personal property or trade fixtures to be billed to and paid
directly by Tenant; (d) resulting from Landlord Work, Tenant Work or Tenant Alterations to the Premises, whether title thereto is in Landlord or Tenant; or (e) upon this transaction. Taxes paid by Tenant pursuant to this Section 4.05 shall not be
included in any computation of Taxes as part of Operating Expenses. 
  
 ARTICLE FIVE 
 SECURITY DEPOSIT 
  
 Tenant concurrently with the execution of this Lease shall pay to Landlord in immediately available funds the Security Deposit. The Security Deposit may be applied by
Landlord to cure, in whole or part, any default of Tenant under this Lease, and upon notice by Landlord of such application, Tenant shall replenish the Security Deposit in full by paying to Landlord within ten (10) days of demand the amount so
applied. Landlord’s application of the Security Deposit shall not constitute a waiver of Tenant’s default to the extent that the Security Deposit does not fully compensate Landlord for all losses, damages, costs and expenses incurred by
Landlord in connection with such default and shall not prejudice any other rights or remedies available to Landlord under this Lease or by Law. Landlord shall not pay any interest on the Security Deposit. Landlord shall not be required to keep the
Security Deposit separate from its general accounts. The Security Deposit 

  

 8 

 
shall not be deemed an advance payment of Rent, nor a measure of damages for any default by Tenant under this Lease, nor shall it be a bar or defense of any
action which Landlord may at any time commence against Tenant. In the absence of evidence satisfactory to Landlord of an assignment of the right to receive the Security Deposit or the remaining balance thereof, Landlord may return the Security
Deposit to the original Tenant, regardless of one or more assignments of this Lease. Upon the transfer of Landlord’s interest under this Lease, Landlord’s obligation to Tenant with respect to the Security Deposit shall terminate upon
transfer to the transferee of the Security Deposit, or any balance thereof and the assumption by the transferee of Landlord’s obligations with respect thereto. If Tenant shall fully and faithfully comply with all the terms, provisions,
covenants, and conditions of this Lease, the Security Deposit, or any balance thereof, shall be returned to Tenant within thirty (30) days after Landlord recovers possession of the Premises. Tenant hereby waives any and all rights of Tenant under
the provisions of Section 1950.7 of the California Civil Code or other Law regarding security deposits. 
  
 ARTICLE SIX 
 UTILITIES & SERVICES 
  

	6.01	LANDLORD’S GENERAL SERVICES 

  
 Landlord shall provide maintenance and services as provided in Article Eight. 
  

	6.02	TENANT TO OBTAIN & PAY DIRECTLY 

  
 (a) Tenant shall be responsible for and shall pay promptly all charges for gas, electricity, sewer, heat, light, power, telephone, refuse pickup (to be
performed on a regularly scheduled basis so that accumulated refuse does not exceed the capacity of Tenant’s refuse bins), janitorial service and all other utilities, materials and services furnished directly to or used by Tenant in, on or
about the Premises, together with all taxes thereon. Tenant shall contract directly with the providing companies for such utilities and services. 
  
 (b) Notwithstanding any provision of the Lease to the contrary, without, in each instance, the prior written consent of Landlord which response for such
consent shall not be unreasonably delayed, as more particularly provided in Article Nine, Tenant shall not: (i) make any alterations or additions to the electric or gas equipment or systems or other Building systems. If Landlord does not consent to
such request, Landlord shall indicate the reasons therefor. Tenant’s use of electric current shall at no time exceed the capacity of the wiring, feeders and risers providing electric current to the Premises or the Building. The consent of
Landlord to the installation of electric equipment shall not relieve Tenant from the obligation to limit usage of electricity to no more than such capacity. 
  

	6.03	TELEPHONE SERVICES 

  
 All telegraph, telephone, and communication connections which Tenant may desire outside the Premises shall be subject to Landlord’s prior written approval, in Landlord’s sole discretion, and the location of
all wires and the work in connection therewith shall be performed by contractors approved by Landlord and shall be subject to the direction of Landlord, except that such approval is not required as to Tenant’s cabling from the Premises in a
route designated by Landlord to any telephone cabinet or panel provided for Tenant’s connection to the telephone cable serving the Building, so long as Tenant’s equipment does not require connections different than or additional to those
to the telephone cabinet or panel provided. As to any such connections or work outside the Premises requiring Landlord’s approval, Landlord reserves the right to designate and control the entity or entities providing telephone or other
communication cable installation, removal, repair and maintenance outside the Premises and to restrict and control access to telephone cabinets or panels. In the event Landlord designates a particular vendor or vendors to provide such cable
installation, removal, repair and maintenance for the Building, Tenant agrees to abide by and participate in such program. Tenant shall be responsible for and shall pay all costs incurred in connection with the installation of telephone cables and
communication wiring in the Premises, including any hook-up, access and maintenance fees related to the installation of such wires and cables in the Premises and the commencement of service therein, and the maintenance thereafter of such wire and
cables; and there shall be included in Operating Expenses for the Building all installation, removal, hook-up or maintenance costs incurred by Landlord in connection with telephone cables and communication wiring serving the Building which are not
allocable to any individual users of such service but are allocable to the Building generally. If Tenant fails to maintain all telephone cables and communication wiring in the Premises and such failure affects or interferes with the operation or
maintenance of any other telephone cables or communication wiring serving the Building, Landlord or any vendor hired by Landlord may enter into and upon the Premises forthwith and perform such repairs, restorations or alterations as Landlord deems
necessary in order to eliminate any such interference (and Landlord may recover from Tenant all of Landlord’s costs in connection therewith). No later than the Termination Date, Tenant agrees to remove all telephone cables and communication
wiring installed by Tenant for and during Tenant’s occupancy, which Landlord shall request Tenant to remove. Tenant agrees that neither Landlord nor any of its agents or employees shall be liable to Tenant, or any of Tenant’s employees,
agents, customers or invitees or anyone claiming through, by or under Tenant, for any damages, injuries, losses, expenses, claims or causes of action because of any interruption, diminution, delay or discontinuance at any time for any reason in the
furnishing of any telephone or other communication service to the Premises and the Building.

	6.04	FAILURE OR INTERRUPTION OF UTILITY OR SERVICE 

  
 To the extent that any equipment or machinery furnished or maintained by Landlord outside the Premises is used in the delivery of utilities directly obtained by Tenant
pursuant to Section 6.02 and breaks down or ceases to function properly, Landlord shall use reasonable diligence to repair same promptly. In the event of any failure, stoppage or interruption of, or change in, any utilities or services supplied by
Landlord which are not directly obtained by Tenant, Landlord shall use reasonable diligence to have service promptly resumed. In either event covered by the preceding two sentences, if the cause of any such failure, stoppage or interruption of, or
change in, utilities or services is within the control of a public utility, other public or quasi-public entity, or utility provider outside Landlord’s control, notification to such utility or entity of such failure, stoppage or interruption
and request to remedy the same shall constitute “reasonable diligence” by Landlord to have service promptly resumed. Notwithstanding any other provision of this Section to the contrary, in the event of any failure, stoppage or interruption
of, or change in, any utility or other service furnished to the Premises or the Project resulting from any cause, including changes in service provider or Landlord’s compliance with any voluntary or similar governmental or business guidelines
now or hereafter published or any requirements now or hereafter established by any governmental agency, board or bureau having jurisdiction over the operation of the Property: (a) Landlord shall not be liable for, and Tenant shall not be entitled
to, any abatement or reduction of Rent; (b) no such failure, stoppage, or interruption of any such utility or service shall constitute an eviction of Tenant or relieve Tenant of the obligation to perform any covenant or agreement of this Lease to be
performed by Tenant; (c) Landlord shall not be in breach of this Lease nor be liable to Tenant for damages or otherwise. 
  

	6.05	CHOICE OF SERVICE PROVIDER 

  
 Tenant acknowledges that Landlord may, at Landlord’s sole option, to the extent permitted by applicable law, elect to change, from time to time, the company or companies which provide services (including
electrical service, gas service, water, telephone and technical services) to the Property, the Premises and/or its occupants. Notwithstanding anything to the contrary set forth in this Lease, Tenant acknowledges that Landlord has not and does not
make any representations or warranties concerning the identity or identities of the company or companies which provide services to the Property and the Premises or its occupants and Tenant acknowledges that the choice of service providers and
matters concerning the engagement and termination thereof shall be solely that of Landlord. The foregoing provision is not intended to modify, amend, change or otherwise derogate any provision of this Lease concerning the nature or type of service
to be provided or any specific information concerning the amount thereof to be provided. Tenant agrees to cooperate with Landlord and each of its service providers in connection with any change in service or provider. 
  

	6.06	SIGNAGE 

  
 Tenant shall not install any signage within the Project, the Building or the Premises without obtaining the prior written approval of Landlord, and Tenant shall be responsible for the installation and maintenance of
any such signage installed by Tenant. Any such signage shall comply with Landlord’s current Project signage criteria and all Laws. 
  
 ARTICLE SEVEN

PREMISES 
  

	7.01	POSSESSION AND USE OF PREMISES 

  
 (a) Tenant shall occupy and use the Premises only for the uses specified in Section 1.01(17) to conduct Tenant’s business. Tenant shall not occupy or
use the Premises (or permit the use or occupancy of the Premises) for any purpose or in any manner which: (1) is unlawful or in violation of any Law or Environmental Law; (2) may be dangerous to persons or property or which may increase the cost of,
or invalidate, any policy of insurance carried on the Building or covering its operations; (3) is contrary to or prohibited by the terms and conditions of this Lease or the rules and regulations as provided in Article Eighteen; (4) contrary to or
prohibited by the articles, bylaws or rules of any owner’s association affecting the Project; (5) is improper, immoral, or objectionable; (6) would obstruct or interfere with the rights of other tenants or occupants of the Building or the
Project, or injure or annoy them, or would tend to create or continue a nuisance; or (7) would constitute any waste in or upon the Premises or Project. 
  
 (b) Landlord and Tenant acknowledge that the Americans With Disabilities Act of 1990 (42 U.S.C. §12101 et seq.) and regulations and guidelines
promulgated thereunder, as all of the same may be amended and supplemented from time to time (collectively referred to herein as the “ADA”) establish requirements for business operations, accessibility and barrier removal, and that such
requirements may or may not apply to the Premises, the Building and the Project depending on, among other things: (1) whether Tenant’s business is deemed a “public accommodation” or “commercial facility”, (2) whether such
requirements are “readily achievable”, and (3) whether a given alteration affects a “primary function area” or triggers “path of travel” requirements. The parties hereby agree that: (a) Landlord shall be responsible for
ADA Title III compliance in the Common Areas outside the Building, except as provided below, (b) Tenant shall be responsible for ADA Title III compliance in the Premises, including any leasehold improvements or other work to be performed in the
Premises under or in connection with this Lease, (c) 
  
 Landlord may perform, or
require that Tenant perform, and Tenant shall be responsible for the cost of, ADA Title III “path of travel” requirements triggered by Tenant Additions (except to the extent triggered by Tenant 

  

 10 

 
Work or Tenant Alterations to prepare the Premises for Tenant’s initial occupancy) in the Premises, and (d) Landlord may perform, or require Tenant to
perform, and Tenant shall be responsible for the cost of, ADA Title III compliance in the Common Areas necessitated by the Building being deemed to be a “public accommodation” instead of a “commercial facility” as a result of
Tenant’s use of the Premises. Tenant shall be solely responsible for requirements under Title I of the ADA relating to Tenant’s employees. 
  
 (c) Landlord and Tenant agree to cooperate and use commercially reasonable efforts to participate in traffic management programs generally applicable to
businesses located in or about the area and Tenant shall encourage and support van and car pooling by, and staggered and flexible working hours for, its office workers and service employees to the extent reasonably permitted by the requirements of
Tenant’s business. Neither this Section or any other provision of this Lease is intended to or shall create any rights or benefits in any other person, firm, company, governmental entity or the public. 
  
 (d) Tenant agrees to cooperate with Landlord and to comply with any and all
guidelines or controls concerning energy management imposed upon Landlord by federal or state governmental organizations or by any energy conservation association to which Landlord is a party or which is applicable to the Building. 
  

	7.02	HAZARDOUS MATERIAL 

  
 (a) Tenant shall not use, generate, manufacture, produce, store, release, discharge, or dispose of, on, under or about the Premises or any part of the
Project, or transport to or from the Premises or any part of the Project, any Hazardous Material or allow its employees, agents, contractors, licensees, invitees or any other person or entity to do so. Notwithstanding the foregoing, Tenant shall be
permitted to use and store in, and transport to and from, the Premises the Hazardous Material identified on Exhibit D hereto and by this reference incorporated herein (“Permitted Hazardous Material”) so long as: (a) each item of the
Permitted Hazardous Material is used or stored in, or transported to and from, the Premises only to the extent necessary for Tenant’s operation of its business at the Premises; (b) at no time shall any Permitted Hazardous Material be in use or
storage at the Premises in excess of the quantity specified therefor in Exhibit D; and (c) the conditions set forth in this Section 7.02 are strictly complied with. The right to use and store in, and transport to and from, the Premises the
Permitted Hazardous Material is personal to Maxygen, Inc. and may not be assigned or otherwise transferred by Maxygen, Inc., without the prior written consent of Landlord, which consent may be withheld in Landlord’s sole discretion. Any consent
by Landlord pursuant to Article Ten of this Lease to an assignment, transfer, subletting, mortgage, pledge, hypothecation or encumbrance of this Lease, and any interest therein or right or privilege appurtenant thereto, shall not constitute consent
by Landlord to the use or storage at, or transportation to, the Premises of any Hazardous Material (including a Permitted Hazardous Material) by any such assignee, sublessee or transferee unless Landlord expressly agrees otherwise in writing. Any
consent by Landlord to the use or storage at, or transportation to or from the Premises, of any Hazardous Material (including a Permitted Hazardous Material) by an assignee, sublessee or transferee of Tenant shall not constitute a waiver of
Landlord’s right to refuse such consent as to any subsequent assignee or transferee. 
  
 (b) Tenant shall comply with and shall cause Tenant’s employees, agents, contractors, licensees, invitees or any other person or entity for whom Tenant is responsible (collectively, “Tenant’s
Agents”) to comply with, and shall keep and maintain the Premises and cause Tenant’s Agents to keep and maintain the Premises, in compliance with all Environmental Laws. Neither Tenant nor Tenant’s Agents shall violate, or cause or
permit the Premises to be in violation of, any Environmental Laws. 
  
 Tenant shall, at its own expense prior to Tenant’s use and occupancy, procure, maintain in effect and comply with all conditions of any and all permits, licenses and other governmental and regulatory approvals required for
Tenant’s use of the Premises. Tenant shall cause any and all Hazardous Material removed from the Premises to be removed and transported solely by duly licensed handlers to duly licensed facilities for final disposal of such materials and
wastes. Tenant acknowledges that the sewer piping at the Project is made of ABS plastic. Accordingly, without Landlord’s prior written consent, which may be given or withheld in Landlord’s sole discretion, only ordinary domestic sewage is
permitted to be put into the drains at the Premises. UNDER NO CIRCUMSTANCES SHALL TENANT EVER DEPOSIT ANY ESTERS OR KETONES (USUALLY FOUND IN SOLVENTS TO CLEAN UP PETROLEUM PRODUCTS) IN THE DRAINS AT THE PREMISES. If Tenant desires to put any
substances other than ordinary domestic sewage into the drains, it shall first submit to Landlord a complete description of each such substance, including its chemical composition, and a sample of such substance suitable for laboratory testing.
Landlord shall promptly determine whether or not the substance can be deposited into the drains and its determination shall be absolutely binding on Tenant. Upon demand, Tenant shall reimburse Landlord for expenses incurred by Landlord in making
such determination. If any substances not so approved hereunder are deposited in the drains in Tenant’s Premises, Tenant shall be liable to Landlord for all damages resulting therefrom, including, but not limited to, all costs and expenses
incurred by Landlord in repairing or replacing the piping so damaged. 
  
 Tenant agrees to provide Landlord with: (1) a copy of any hazardous material management plan or similar document required by any federal, state or local governmental or regulatory authority to be submitted by Tenant; (2) copies of all
permits, licenses and other governmental and regulatory approvals with respect to the use of Hazardous Material; (3) copies of hazardous waste manifests reflecting the legal and proper disposal of all Hazardous Material removed from the Premises;
and (4) copies of all reports, studies and written results of tests or inspections concerning the Premises or any part of the Project with respect to Hazardous Material, including the “Plans” hereinafter defined (collectively
“Documents”). Tenant shall deliver all Documents to Landlord promptly following the earlier of (i) Tenant’s submission of such Documents to the 

  

 11 

 
requesting governmental agency, or (ii) Tenant’s receipt of such Documents (Tenant hereby agreeing that it shall exercise diligent efforts to
expeditiously obtain copies of any such Documents known by Tenant to exist). 
  
 (c) Upon commencing any activity involving Hazardous Material on the Premises, and continuing thereafter throughout the term of this Lease, Tenant shall initiate and maintain the systems set forth in the following
(collectively, “Plans”) in order to ensure the routine monitoring of the levels of Hazardous Material which may be present on, under or about the Premises or any part of the Project or properties adjoining or in the vicinity of the Project
as the result of the activities of Tenant or Tenant’s Agents and to ensure continued compliance with the procedures and regulations concerning the handling, storage, use and disposal of Hazardous Material: (1) each permit, license or other
governmental or regulatory approval with respect to the use of Hazardous Material, (2) each Hazardous Material management plan or similar document required by any federal, state, or local governmental or regulatory entity, (3) each plan for handling
and disposing of Hazardous Material necessary to comply with Environmental Laws prepared by or on behalf of Tenant or Tenant’s Agents (whether or not required to be submitted to a governmental agency). Copies of the foregoing described Plans
are listed on Exhibit E hereto and attached to this Lease as Exhibits E-1 through E-    . 
  
 (d) Not less often than once each calendar year during the term of this Lease, Tenant shall provide Landlord with a written report which shall set forth
the results of the monitoring of Hazardous Material during the previous calendar year. Landlord may elect (but shall not be obligated) to retain an independent consultant experienced in the use and management of Hazardous Material for the purpose of
reviewing any information received by Landlord in connection with Hazardous Material. Pursuant to such review, Landlord’s consultant may make recommendations in connection with Tenant’s control of Hazardous Material on the Premises, and
Tenant shall implement, at Tenant’s sole cost, the recommendations of Landlord’s consultant. Landlord’s failure to appoint any consultant shall not relieve Tenant of any of Tenant’s obligations under this Lease relating to
Hazardous Material nor constitute a waiver of Landlord’s rights under this Lease. In the event that Landlord’s consultant discovers that Tenant’s procedures constitute or will result in a non-deminimis violation of the provisions of
this Section, Tenant shall promptly cure such violation and, as necessary, modify its procedures, at its sole cost and expense, to the reasonable satisfaction of Landlord’s consultant. 
  
 (e) Landlord may install permanent or other testing wells or devices at or
about the Premises or any part of the Project, and may cause the ground water to be tested to detect the presence of Hazardous Material at least once every twelve (12) months during the term of this Lease by the use of such wells or devices as are
then customarily used for such purposes. If Tenant so requests in writing, Landlord shall supply Tenant with a copy of any such test results. The costs of any such tests, and the installation, maintenance, repair, removal, closure and replacement of
such wells or devices shall be included in Operating Expenses pursuant to this Lease; provided, however, such costs shall be borne solely by Tenant if the same are incurred by Landlord based upon Landlord’s reasonable belief, at the time such
testing is initiated, that Tenant is in breach of its obligations under this Section 7.02 or if, following the initiation of such testing, the presence of Hazardous Material is detected and Tenant or Tenant’s Agents are responsible therefor.
Tenant’s obligations under this Section 7.02(e)shall survive the expiration or earlier termination of this Lease. 
  
 (f) Landlord and its representative shall have the right, at the following times, to enter the Premises and to: (i) conduct any testing, monitoring and
analysis for Hazardous Material; (ii) review any documents, materials, inventory, financial data or notices or correspondence to or from private parties or governmental or regulatory authorities in connection therewith; and (iii) review all storage,
use, transportation and disposal facilities and procedures associated with the storage, use, transportation and disposal of Hazardous Material (collectively, “Inspection”): 
  
 (1) Once every six (6) months for the first twelve (12) months after the later of the date Tenant introduces Hazardous
Material to the Premises pursuant to this Section 7.02 or notifies Landlord of such use, and once every twelve (12) months thereafter throughout the term of this Lease. Tenant agrees to notify Landlord at least five (5) business days prior to the
use or storage in, or transportation to, the Premises of Hazardous Material; and 
  
 (2) At any time during the term of this Lease if, in Landlord’s reasonable judgment, Tenant is breaching its obligation under this Section 7.02 or is not in compliance with any other provision of this Lease.

  
 All costs and expenses incurred by Landlord in connection with
any Inspection pursuant to this Section 7.02(f) shall, subject to Section 7.02(n) below, become due and payable by Tenant as additional Rent, upon presentation by Landlord of an invoice therefor. 
  
 (g) Tenant shall give prompt written notice to Landlord of: 
  
 (1) any proceeding or inquiry by, notice from, or order of any governmental
authority (including the California State Department of Health Services) with respect to the presence of any Hazardous Material on, under or about the Premises or any part of the Project or the migration thereof from or to other property;

  
 (2) all claims made or threatened by any third party against
Tenant, the Premises or any part of the Project relating to any loss or injury resulting from any Hazardous Material; and 
  

 12 

 (3) any spill, release, discharge or nonroutine disposal of Hazardous Material that occurs with respect
to the Premises or operations at the Premises by Tenant or Tenant’s Agents; 
  
 (4) all matters of which Tenant is required to give notice pursuant to Sections 25249.5 et seq. and 25359.7 of the California Health and Safety Code; and 
  
 (5) Tenant’s discovery of any occurrence or condition on, under or about
the Premises or any part of the Project or any real property adjoining or in the vicinity of the Premises or the Project that could cause the Premises or any part of the Project to be subject to any restrictions on the ownership, occupancy,
transferability or use of the Premises or any part of the Project under any Environmental Laws, including without limitation, Tenant’s discovery of any occurrence or condition on any real property adjoining or in the vicinity of the Premises or
the Project that could cause the Premises or any part of the Project to be classified as “border zone property” under the provisions of California Health and Safety Code Sections 25220 et seq. or any regulation adopted in
accordance therewith, or to be otherwise subject to any restrictions on the ownership, occupancy, transferability or use of the Premises or any part of the Project under any Environmental Laws. 
  
 (h) Landlord shall have the right to join and participate in, as a party if
it so elects, any legal proceedings or actions affecting the Premises or any part of the Project initiated in connection with any Environmental Laws and have its attorneys’ fees in connection therewith paid by Tenant. In addition, Tenant shall
not take any remedial action in response to the presence of any Hazardous Material in, under, or about the Premises or the Project (except in the case where loss of life or substantial property damage is imminent or immediate action is required by
any governmental entity, in which event Tenant shall take immediate remedial action), nor enter into any settlement agreement, consent decree or other compromise in respect to any claims relating to any Hazardous Material in any way connected with
the Premises or the Project, without first notifying Landlord of Tenant’s intention to do so and affording Landlord ample opportunity to appear, intervene or otherwise appropriately assert and protect Landlord’s interest with respect
thereto. 
  
 (i) To the extent permitted by law, Tenant hereby
indemnifies and agrees to protect, defend and hold the Indemnitees harmless against any actions, claims, demands, liability, costs and expenses, including attorneys’ fees and costs, arising from the use, generation, manufacture, production,
storage, release, threatened release, discharge, disposal, transportation to or from, or presence of any Hazardous Material on, under or about the Premises or any part of the Project caused by Tenant or by Tenant’s Agents (collectively a
“Release”) including, without limitation: (1) all foreseeable consequential damages, including loss of rental income and diminution in property value; (2) the costs of any investigation, monitoring, removal, restoration, abatement, repair,
cleanup, detoxification or other ameliorative work of any kind or nature (collectively “Remedial Work”) and the preparation and implementation of any closure, remedial or other required plans; (3) any injury to or death of persons or
damage to or destruction of property; and (4) any failure of Tenant or Tenant’s Agents to observe the covenants of this Section 7.02. For purposes of this Section 7.02(i), any acts or omissions of Tenant’s Agents (whether or not they are
negligent, intentional, willful or unlawful) shall be strictly attributable to Tenant. In case of any action of proceeding brought against the Indemnitees by reason of any such claim, upon notice from Landlord, Tenant covenants to defend such action
or proceeding by counsel chosen by Landlord, in Landlord’s sole discretion. Landlord reserves the right to settle, compromise or dispose of any and all actions, claims and demands related to the foregoing indemnity. Tenant’s obligations
under this Section 7.02(i) shall survive the expiration or earlier termination of this Lease. The foregoing indemnity shall not operate to relieve Landlord of any liability Landlord has under Environmental Laws to the extent Hazardous Material are
present on, under or about the Premises or the Project prior to delivery to Tenant of possession of the Premises. 
  
 In no event shall Landlord be responsible to Tenant for the presence of Hazardous Material in, on or about the Premises or the Project to the extent
caused or contributed to by any third party. 
  
 (j) Within
forty-five (45) days following the end of Tenant’s fiscal year, Tenant shall provide Landlord with financial statements prepared in accordance with generally accepted accounting principles consistently applied and certified as true and correct
by Tenant’s independent certified public accountant setting forth Tenant’s performance for the applicable fiscal year. So long as Tenant is not a publically traded company, the preceding sentence shall not apply, but Tenant shall make
available to Landlord, at mutually convenient times, at Landlord’s request, from time to time, financial statements prepared in accordance with generally accepted accounting principles consistently applied and certified as true and correct by
Tenant’s independent certified public accountant setting forth Tenant’s performance for the applicable fiscal year, for inspection and review by Landlord at the Premises. As of the execution of this Lease, Tenant’s fiscal year ends
December 31. Tenant shall provide Landlord with prompt written notice of any change in Tenant’s fiscal year. If at any time it reasonably appears to Landlord that Tenant is not maintaining sufficient insurance or is not otherwise financially
capable of fulfilling its obligations under this Section 7.02, whether or not such obligations have accrued, become liquidated, conditional or contingent, Tenant shall procure and thereafter maintain in full force and effect such insurance or other
form of financial assurance, with or from companies or persons and in forms reasonably acceptable to Landlord, as Landlord may from time to time request. 
  
 (k) Upon any Release, Tenant shall, subject to Section 7.02(h), promptly notify Landlord of the Release and shall, at its sole expense and immediately
after demand by Landlord, commence to perform and thereafter diligently prosecute to completion such Remedial Work as is necessary to restore the Premises, Project or any other property affected by the Release to the condition existing prior to the
use of any Hazardous Material by Tenant and/or Tenant’s Agents. All such Remedial Work shall be performed: (1) in conformance with the requirements of all applicable Environmental Laws; (2) by one or more contractors, 

  

 13 

 
approved in advance in writing by Landlord; and (3) under the supervision of a consulting engineer approved in advance in writing by Landlord. All costs and
expenses of such Remedial Work shall be paid by Tenant including the charges of such contractor(s) and/or the consulting engineer and Landlord’s reasonable attorneys’ fees and costs incurred in connection with the monitoring or review of
such Remedial Work. In the event Tenant shall fail to timely commence, or cause to be commenced, or fail to diligently prosecute to completion, such Remedial Work, Landlord may, but shall not be required to, cause such Remedial Work to be performed
and all costs and expenses thereof, or incurred in connection therewith, shall become immediately due and payable by Tenant. Tenant’s obligations under this Section 7.02(k) shall survive the expiration or sooner termination of this Lease.

  
 (l) Hazardous Material shall include by way of illustration,
and without limiting the generality of the definition of Hazardous Material in Section 1.03, the following: (i) those substances included within the definitions of “hazardous substances,” “hazardous materials,” “toxic
substances” or “solid waste” under all present and future federal, state and local laws (whether under common law, statute, rule, regulation or otherwise) relating to the protection of human health or the environment, including
California Senate Bill 245 (Statutes of 1987, Chapter 1302), the Safe Drinking Water and Toxic Enforcement Act of 1986 (commonly known as Proposition 65) and the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as
amended, 42 U.S.C. Section 9601 et seq., the Resource Conservation and Recovery Act of 1976, 42 U.S.C. Section 6901 et seq., and the Hazardous Materials Transportation Act, 49 U.S.C. Sections 1801, et seq., all as
heretofore and hereafter amended, or in any regulations promulgated pursuant to said laws; (ii) those substances defined as “hazardous wastes” in Section 25117 of the California Health & Safety Code or as “hazardous
substances” in Section 25316 of the California Health & Safety Code, or in any regulations promulgated pursuant to said laws; (iii) those substances listed in the United States Department of Transportation Table (49 CFR 172.101 and
amendments thereto) or designated by the Environmental Protection Agency (or any successor agency) as hazardous substances (see, e.g., 40 CFR Part 302 and amendments thereto); (iv) such other substances, materials and wastes which are
or become regulated under applicable local, state or federal law or by the United States government or which are or become classified as hazardous or toxic under federal, state or local laws or regulations, including California Health & Safety
Code, Division 20, and Title 26 of the California Code of Regulations; and (v) any material, waste or substance which contains petroleum, asbestos or polychlorinated biphenyls, is designated as a “hazardous substance” pursuant to Section
311 of the Clean Water Act of 1977, 33 U.S.C. Sections 1251, et seq. (33 U.S.C. § 1321), is listed pursuant to Section 307 of the Clean Water Act of 1977 (33 U.S.C. § 1317), or contains any flammable, explosive or radioactive
material. 
  
 (m) In addition to Tenant’s obligations
pursuant to Article Twelve of this Lease, Tenant shall, on the expiration or sooner termination of this Lease, surrender the Premises to Landlord free of Hazardous Material for which Tenant is responsible hereunder. If Tenant fails to so surrender
the Premises and the Project, the provisions of Section 7.02(i) shall apply. Landlord shall have the right, but not the obligation, to appoint a consultant, at Tenant’s expense, to conduct an investigation to determine whether any Hazardous
Material are located in or about the Premises or the Project, and to determine the corrective measures required to remove such Hazardous Material. Tenant, at its expense, shall comply with all recommendations of the consultant. A failure by Landlord
to appoint such a consultant shall in no way relieve Tenant of any of Tenant’s obligations set forth in this Lease relating to Hazardous Material, nor constitute a waiver of Landlord’s rights under this Lease. Tenant’s obligations
under this Section 7.02(m) shall survive the expiration or earlier termination of this Lease. 
  
 (n) Except as otherwise provided in Section 7.02(d) (concerning the implementation of consultant recommendations) and Section 7.02(k) (concerning the monitoring and review of Remedial Work), all costs incurred by
Landlord in retaining a consultant for any purpose contained in this Section 7.02 shall be included in Operating Expenses under this Lease unless Landlord retains a consultant pursuant to this Section 7.02, and such consultant reasonably determines
after appropriate review of information and/or inspection that Tenant is breaching its obligations under this Lease to comply with this Section 7.02, in which event all costs and expenses incurred by Landlord in connection with any such review,
inspection, and/or implementation of recommendations pursuant to this Section 7.02 shall become due and payable by Tenant as additional Rent, upon presentation by Landlord of an invoice therefor. 
  
 (o) Upon any violation of any of the foregoing covenants, Landlord shall be
entitled to exercise all remedies available to a landlord against a defaulting tenant, including but not limited to those set forth in Article Eleven of this Lease. No action by Landlord hereunder shall impair the obligations of Tenant pursuant to
Section 7.02. 
  

	7.03	LANDLORD ACCESS TO PREMISES; APPROVALS 

  
 (a) Tenant shall permit Landlord to erect, use and maintain pipes, ducts, wiring and conduits in and through the Premises, so long as Tenant’s use,
layout or design of the Premises is not materially affected or altered. Landlord or Landlord’s agents shall have the right to enter upon the Premises in the event of an emergency, or, upon twenty-four (24) hours prior notice to Tenant, to
inspect the Premises, to perform janitorial and other services (if any), to conduct safety and other testing in the Premises and to make such repairs, alterations, improvements or additions to the Premises or the Building or other parts of the
Property as Landlord may deem necessary or desirable (including all alterations, improvements and additions in connection with a change in service provider or providers). Janitorial and cleaning services (if any) shall be performed after normal
business hours. Any entry or work by Landlord may be during normal business hours and Landlord may use reasonable efforts to ensure that any entry or work shall not materially interfere with Tenant’s occupancy of the Premises. 
  

 14 

 (b) If Tenant shall not be personally present to permit an entry into the Premises when for any reason an
entry therein shall be necessary or permissible, Landlord (or Landlord’s agents), after attempting to notify Tenant (unless Landlord believes an emergency situation exists), may enter the Premises without rendering Landlord or its agents liable
therefor, and without relieving Tenant of any obligations under this Lease. 
  
 (c) Upon twenty-four (24) hours notice to Tenant (or such shorter notice as may be reasonable in an emergency), Landlord may enter the Premises for the purpose of conducting such inspections, tests and studies as
Landlord may deem desirable or necessary to confirm Tenant’s compliance with all Laws and Environmental Laws or for other purposes necessary in Landlord’s reasonable judgment to ensure the sound condition of the Property and the systems
serving the Property. Landlord’s rights under this Section 7.02(c) are for Landlord’s own protection only, and Landlord has not, and shall not be deemed to have assumed, any responsibility to Tenant or any other party as a result of the
exercise or non-exercise of such rights, for compliance with Laws or Environmental Laws or for the accuracy or sufficiency of any item or the quality or suitability of any item for its intended use. 
  
 (d) Landlord may do any of the foregoing, or undertake any of the inspection
or work described in the preceding paragraphs without such action constituting an actual or constructive eviction of Tenant, in whole or in part, or giving rise to an abatement of Rent by reason of loss or interruption of business of the Tenant, or
otherwise. 
  
 (e) The review, approval or consent of Landlord
with respect to any item required or permitted under this Lease is for Landlord’s own protection only, and Landlord has not, and shall not be deemed to have assumed, any responsibility to Tenant or any other party, as a result of the exercise
or non-exercise of such rights, for compliance with Laws or Environmental Laws or for the accuracy or sufficiency of any item or the quality or suitability of any item for its intended use. 
  

	7.04	QUIET ENJOYMENT 

  
 Landlord covenants, in lieu of any implied covenant of quiet possession or quiet enjoyment, that so long as Tenant is in compliance with the covenants and conditions set forth in this Lease, Tenant shall have the
right to quiet enjoyment of the Premises without hindrance or interference from Landlord or those claiming through Landlord, and subject to the covenants and conditions set forth in the Lease and to the rights of any Mortgagee or ground lessor.

  
 ARTICLE EIGHT

	8.01	LANDLORD’S MAINTENANCE 

  
 Subject to Article Fourteen and Section 8.02, Landlord shall maintain the structural portions of the Building, the roof, exterior walls and exterior doors, foundation, and underslab standard sewer system of the
Building in good, clean and safe condition, and shall use reasonable efforts, through Landlord’s program of regularly scheduled preventive maintenance, to keep the Building’s standard heating, ventilation and air conditioning
(“HVAC”) equipment in reasonably good order and condition. Notwithstanding the foregoing, Landlord shall have no responsibility to repair the Building’s standard heating, ventilation and air conditioning equipment, and all such
repairs shall be performed by Tenant pursuant to the terms of Section 8.02. Landlord shall also (a) maintain the landscaping, parking facilities and other Common Areas of the Project, and (b) wash the outside of exterior windows at intervals
reasonably determined by Landlord. Except as provided in Article Fourteen and Article Fifteen, there shall be no abatement of rent, no allowance to Tenant for diminution of rental value and no liability of Landlord by reason of inconvenience,
annoyance or any injury to or interference with Tenant’s business arising from the making of or the failure to make any repairs, alterations or improvements in or to any portion of the Project or in or to any fixtures, appurtenances or
equipment therein. Tenant waives the right to make repairs at Landlord’s expense under any law, statute or ordinance now or hereafter in effect. 
  

	8.02	TENANT’S MAINTENANCE 

  
 Subject to the provisions of Article Fourteen, Tenant shall, at Tenant’s sole cost and expense, make all repairs to the Premises and fixtures therein which Landlord is not required to make pursuant to Section
8.01, including repairs to the interior walls, ceilings and windows of the Premises, the interior doors, Tenant’s signage, and the electrical, life-safety, plumbing and heating, ventilation and air conditioning systems located within or serving
the Premises and shall maintain the Premises, the fixtures and utilities systems therein, and the area immediately surrounding the Premises (including all garbage enclosures), in a good, clean and safe condition. Tenant shall deliver to Landlord a
copy of any maintenance contract entered into by Tenant with respect to the Premises. Tenant shall also, at Tenant’s expense, keep any non-standard heating, ventilating and air conditioning equipment and other non-standard equipment in the
Building in good condition and repair, using contractors approved in advance, in writing, by Landlord. Notwithstanding Section 8.01 above, but subject to the waivers set forth in Section 16.04, Tenant will pay for any repairs to the Building or the
Project which are caused by any negligence or carelessness, or by any willful and wrongful act, of Tenant or its assignees, subtenants or employees, or of the respective agents of any of the foregoing persons, or of any other persons permitted in
the Building or elsewhere in the Project by Tenant or any of them. Tenant will maintain the Premises, and will leave the Premises upon termination of this Lease, in a safe, clean, neat and sanitary condition. 
  

 15 

 ARTICLE NINE 
 ALTERATIONS AND IMPROVEMENTS 
  

	9.01	TENANT ALTERATIONS 

  
 (a) The following provisions shall apply to the completion of any Tenant Alterations: 
  
 (1) Tenant shall not, except as provided herein, without the prior written consent of Landlord, which
consent shall not be unreasonably withheld, make or cause to be made any Tenant Alterations in or to the Premises or any Property systems serving the Premises. Prior to making any Tenant Alterations, Tenant shall give Landlord ten (10) days prior
written notice (or such earlier notice as would be necessary pursuant to applicable Law) to permit Landlord sufficient time to post appropriate notices of non-responsibility. Subject to all other requirements of this Article Nine, Tenant may
undertake Decoration work without Landlord’s prior written consent. Tenant shall furnish Landlord with the names and addresses of all contractors and subcontractors and copies of all contracts. All Tenant Alterations shall be completed at such
time and in such manner as Landlord may from time to time designate, and only by contractors or mechanics approved by Landlord, which approval shall not be unreasonably withheld, provided, however, that Landlord may, in its sole discretion, specify
the engineers and contractors to perform all work relating to the Building’s systems (including the mechanical, heating, plumbing, security, ventilating, air-conditioning, electrical, communication and the fire and life safety systems in the
Building). The contractors, mechanics and engineers who may be used are further limited to those whose work will not cause or threaten to cause disharmony or interference with Landlord or other tenants in the Building and their respective agents and
contractors performing work in or about the Building. Landlord may further condition its consent upon Tenant furnishing to Landlord and Landlord approving prior to the commencement of any work or delivery of materials to the Premises related to the
Tenant Alterations such of the following as specified by Landlord: architectural plans and specifications, opinions from Landlord’s engineers stating that the Tenant Alterations will not in any way adversely affect the Building’s systems,
necessary permits and licenses, certificates of insurance, and such other documents in such form reasonably requested by Landlord. Upon completion of the Tenant Alterations, Tenant shall deliver to Landlord two (2) sets of as-built mylar and
digitized plans and specifications for the Tenant Alterations. 
  
 (2) Tenant shall pay the cost of all Tenant Alterations and the cost of decorating the Premises and any work to the Property occasioned thereby. In connection with completion of any Tenant Alterations, Tenant shall
pay Landlord hoisting charges at Landlord’s then standard rate. Upon completion of Tenant Alterations, Tenant shall furnish Landlord with contractors’ affidavits and full and final waivers of lien and receipted bills covering all labor and
materials expended and used in connection therewith and such other documentation reasonably requested by Landlord or Mortgagee. 
  
 (3) Tenant agrees to complete all Tenant Alterations (i) in accordance with all Laws, Environmental Laws, all requirements of applicable
insurance companies and in accordance with Landlord’s standard construction rules and regulations, and (ii) in a good and workmanlike manner with the use of good grades of materials. Tenant shall notify Landlord immediately if Tenant receives
any notice of violation of any Law in connection with completion of any Tenant Alterations and shall immediately take such steps as are necessary to remedy such violation. In no event shall such supervision or right to supervise by Landlord nor
shall any approvals given by Landlord under this Lease constitute any warranty by Landlord to Tenant of the adequacy of the design, workmanship or quality of such work or materials for Tenant’s intended use or of compliance with the
requirements of Section 9.01(a)(3)(i) and (ii) above or impose any liability upon Landlord in connection with the performance of such work. 
  
 (b) All Tenant Additions to the Premises whether installed by Landlord or Tenant, shall without compensation or credit to Tenant, become part of the
Premises and the property of Landlord at the time of their installation and shall remain in the Premises, unless pursuant to Article Twelve, Tenant may remove them or is required to remove them at Landlord’s request. 
  

	9.02	LIENS 

  
 Tenant shall not permit any lien or claim for lien of any mechanic, laborer or supplier or any other lien to be filed against the Building, the Land, the Premises, or any other part of the Property arising out of work
performed, or alleged to have been performed by, or at the direction of, or on behalf of Tenant. If any such lien or claim for lien is filed, Tenant shall within ten (10) days of receiving notice of such lien or claim (a) have such lien or claim for
lien released of record or (b) deliver to Landlord a bond in form, content, amount, and issued by surety, satisfactory to Landlord, indemnifying, protecting, defending and holding harmless the Indemnitees against all costs and liabilities resulting
from such lien or claim for lien and the foreclosure or attempted foreclosure thereof. If Tenant fails to take any of the above actions, Landlord, in addition to its rights and remedies under Article Eleven, without investigating the validity of
such lien or claim for lien, may pay or discharge the same and Tenant shall, as payment of additional Rent hereunder, reimburse Landlord upon demand for the amount so paid by Landlord, including Landlord’s expenses and attorneys’ fees.

  

 16 

 ARTICLE TEN 
 ASSIGNMENT AND SUBLETTING 
  

	10.01	ASSIGNMENT AND SUBLETTING 

  
 (a) Without the prior written consent of Landlord, which may be withheld in Landlord’s sole discretion, Tenant may not sublease, assign, mortgage,
pledge, hypothecate or otherwise transfer or permit the transfer of this Lease or the encumbering of Tenant’s interest therein in whole or in part, by operation of Law or otherwise or permit the use or occupancy of the Premises, or any part
thereof, by anyone other than Tenant, provided, however, if Landlord chooses not to recapture the space proposed to be subleased or assigned as provided in Section 10.02, Landlord shall not unreasonably withhold its consent to a subletting or
assignment under this Section 10.01. Tenant agrees that the provisions governing sublease and assignment set forth in this Article Ten shall be deemed to be reasonable. If Tenant desires to enter into any sublease of the Premises or assignment of
this Lease, Tenant shall deliver written notice thereof to Landlord (“Tenant’s Notice”), together with the identity of the proposed subtenant or assignee and the proposed principal terms thereof and financial and other information
sufficient for Landlord to make an informed judgment with respect to such proposed subtenant or assignee at least thirty (30) days prior to the commencement date of the term of the proposed sublease or assignment. If Tenant proposes to sublease less
than all of the Rentable Area of the Premises, the space proposed to be sublet and the space retained by Tenant must each be a marketable unit as reasonably determined by Landlord and otherwise in compliance with all Laws. Landlord shall notify
Tenant in writing of its approval or disapproval of the proposed sublease or assignment or its decision to exercise its rights under Section 10.02 within fifteen (15) days after receipt of Tenant’s Notice (and all required information). In no
event may Tenant sublease any portion of the Premises or assign the Lease to any other tenant of the Project. Tenant shall submit for Landlord’s approval (which approval shall not be unreasonably withheld) any advertising which Tenant or its
agents intend to use with respect to the space proposed to be sublet. 
  
 (b) With respect to Landlord’s consent to an assignment or sublease, Landlord may take into consideration any factors which Landlord may deem relevant, and the reasons for which Landlord’s denial shall be deemed to be reasonable
shall include, without limitation, the following: 
  
 (i) the
business reputation or creditworthiness of any proposed subtenant or assignee is not acceptable to Landlord; or 
  
 (ii) in Landlord’s reasonable judgment the proposed assignee or subtenant would diminish the value or reputation of the Building or Landlord; or

  
 (iii) any proposed assignee’s or subtenant’s use of
the Premises would violate Section 7.01 of the Lease or would violate the provisions of any other leases of tenants in the Project; 
  
 (iv) the proposed assignee or subtenant is either a governmental agency, a school or similar operation, or a medical related practice; or 
  
 (v) the proposed subtenant or assignee is a bona fide prospective tenant of
Landlord in the Project as demonstrated by a written proposal dated within ninety (90) days prior to the date of Tenant’s request; or 
  
 (vi) the proposed subtenant or assignee would materially increase the estimated pedestrian and vehicular traffic to and from the Premises and the
Building. 
  
 In no event shall Landlord be obligated to consider a consent to any
proposed assignment of the Lease which would assign less than the entire Premises. In the event Landlord wrongfully withholds its consent to any proposed sublease of the Premises or assignment of the Lease, Tenant’s sole and exclusive remedy
therefor shall be to seek specific performance of Landlord’s obligations to consent to such sublease or assignment. 
  
 (c) Any sublease or assignment shall be expressly subject to the terms and conditions of this Lease. Any subtenant or assignee shall execute such
documents as Landlord may reasonably require to evidence such subtenant or assignee’s assumption of the obligations and liabilities of Tenant under this Lease. Tenant shall deliver to Landlord a copy of all agreements executed by Tenant and the
proposed subtenant and assignee with respect to the Premises. Landlord’s approval of a sublease, assignment, hypothecation, transfer or third party use or occupancy shall not constitute a waiver of Tenant’s obligation to obtain
Landlord’s consent to further assignments or subleases, hypothecations, transfers or third party use or occupancy. 
  
 (d) For purposes of this Article Ten, an assignment shall be deemed to include a change in the majority control of Tenant, resulting from any transfer,
sale or assignment of shares of stock of Tenant occurring by operation of Law or otherwise if Tenant is a corporation whose shares of stock are not traded publicly. If Tenant is a partnership, any change in the partners of Tenant shall be deemed to
be an assignment. 
  

	10.02	INTENTIONALLY OMITTED 

  

 17 

	10.03	EXCESS RENT 

  
 Tenant shall pay Landlord on the first day of each month during the term of the sublease or assignment, fifty percent (50%) of the amount by which the sum of all rent and other consideration (direct or indirect) due
from the subtenant or assignee for such month exceeds: (i) that portion of the Monthly Base Rent and Rent Adjustments due under this Lease for said month which is allocable to the space sublet or assigned; and (ii) the following costs and expenses
for the subletting or assignment of such space: (1) brokerage commissions and attorneys’ fees and expenses, (2) the actual costs paid in making any improvements or substitutions in the Premises required by any sublease or assignment; and (3)
“free rent” periods, costs of any inducements or concessions given to subtenant or assignee, moving costs, and other amounts in respect of such subtenant’s or assignee’s other leases or occupancy arrangements. All such costs and
expenses shall be amortized over the term of the sublease or assignment pursuant to sound accounting principles. 
  

	10.04	TENANT LIABILITY 

  
 In the event of any sublease or assignment, whether or not with Landlord’s consent, Tenant shall not be released or discharged from any liability, whether past, present or future, under this Lease, including any
liability arising from the exercise of any renewal or expansion option, to the extent such exercise is expressly permitted by Landlord. Tenant’s liability shall remain primary, and in the event of default by any subtenant, assignee or successor
of Tenant in performance or observance of any of the covenants or conditions of this Lease, Landlord may proceed directly against Tenant without the necessity of exhausting remedies against said subtenant, assignee or successor. After any
assignment, Landlord may consent to subsequent assignments or subletting of this Lease, or amendments or modifications of this Lease with assignees of Tenant, without notifying Tenant, or any successor of Tenant, and without obtaining its or their
consent thereto, and such action shall not relieve Tenant or any successor of Tenant of liability under this Lease. If Landlord grants consent to such sublease or assignment, Tenant shall pay all reasonable attorneys’ fees and expenses incurred
by Landlord with respect to such assignment or sublease. In addition, if Tenant has any options to extend the term of this Lease or to add other space to the Premises, such options shall not be available to any subtenant or assignee, directly or
indirectly without Landlord’s express written consent, which may be withheld in Landlord’s sole discretion. 
  

	10.05	ASSUMPTION AND ATTORNMENT 

  
 If Tenant shall assign this Lease as permitted herein, the assignee shall expressly assume all of the obligations of Tenant hereunder in a written instrument satisfactory to Landlord and furnished to Landlord not
later than fifteen (15) days prior to the effective date of the assignment. If Tenant shall sublease the Premises as permitted herein, Tenant shall, at Landlord’s option, within fifteen (15) days following any request by Landlord, obtain and
furnish to Landlord the written agreement of such subtenant to the effect that the subtenant will attorn to Landlord and will pay all subrent directly to Landlord. 
  

	10.06	TRANSFER TO TENANT AFFILIATE 

  
 Anything in this Section to the contrary notwithstanding, Tenant may assign this Lease or sublet all or a portion of the Premises to any entity which controls, is
controlled by or is under common control with Maxygen, Inc. (each a “Tenant Affiliate”), without the prior consent of Landlord, and Landlord shall have no right to recapture the Premises subject to such sublease or assignment; provided,
however, that in order for any such assignment or sublease to be effective, Landlord shall be given prior written notice of same and any such assignment or sublease shall comply with the requirements set forth in Section 10.05, and shall be in
effect only so long as such entity controls, is controlled by or is under common control with Maxygen, Inc. In addition, no such assignment or sublease shall relieve Tenant of any obligation to be performed by Tenant under this Lease, whether
occurring before or after any such assignment or sublease. For purposes of this Section, the term “control” means (i) the beneficial ownership, directly or indirectly, of not less than sixty percent (60%) of the voting common stock or
equity interests of the controlled entity and (ii) the controlling entity manages, directly or indirectly, the controlled entity.

 The occurrence or existence of any one or more of the following shall constitute a “Default” by Tenant under this Lease: 
  
 (i) Tenant fails to pay any installment or other payment of Rent including Rent Adjustment Deposits or Rent
Adjustments within three (3) days after the date when due; 
  
 (ii) Tenant fails to observe or perform any of the other covenants, conditions or provisions of this Lease or the Workletter and fails to cure such default within fifteen (15) days after written notice thereof to
Tenant, unless the default involves a hazardous condition, which shall be cured forthwith or unless the failure to perform is a Default for which this Lease specifies there is no cure or grace period; 
  

 18 

 (iii) the interest of Tenant in this Lease is levied upon under execution or other legal
process; 
  
 (iv) a petition is filed by or
against Tenant to declare Tenant bankrupt or seeking a plan of reorganization or arrangement under any Chapter of the Bankruptcy Act, or any amendment, replacement or substitution therefor, or to delay payment of, reduce or modify Tenant’s
debts, which in the case of an involuntary action is not discharged within thirty (30) days; 
  
 (v) Tenant is declared insolvent by Law or any assignment of Tenant’s property is made for the benefit of creditors; 
  
 (vi) a receiver is appointed for Tenant or Tenant’s
property, which appointment is not discharged within thirty (30) days; 
  
 (vii) any action taken by or against Tenant to reorganize or modify Tenant’s capital structure in a materially adverse way which in the case of an involuntary action is not discharged within thirty (30) days;

  
 (viii) upon the dissolution of Tenant;

  
 (ix) upon the third occurrence within any
Lease Year that Tenant fails to pay Rent when due or has breached a particular covenant of this Lease (whether or not such failure or breach is thereafter cured within any stated cure or grace period or statutory period); or 
  
 (x) if Tenant or any Tenant Affiliate holding any other
lease with Landlord for premises in the Project is in default under such lease after any applicable notice and grace period or cure period. 
  

	11.02	LANDLORD’S REMEDIES 

  
 (a) A Default shall constitute a breach of the Lease for which Landlord shall have the rights and remedies set forth in this Section 11.02 and all other
rights and remedies set forth in this Lease or now or hereafter allowed by Law, whether legal or equitable, and all rights and remedies of Landlord shall be cumulative and none shall exclude any other right or remedy. 
  
 (b) With respect to a Default, at any time Landlord may terminate
Tenant’s right to possession by written notice to Tenant stating such election. Any written notice required pursuant to Section 11.01 shall constitute notice of unlawful detainer pursuant to California Code of Civil Procedure Section 1161 if,
at Landlord’s sole discretion, it states Landlord’s election that Tenant’s right to possession is terminated after expiration of any period required by Law or any longer period required by Section 11.01. Upon the expiration of the
period stated in Landlord’s written notice of termination (and unless such notice provides an option to cure within such period and Tenant cures the Default within such period), Tenant’s right to possession shall terminate and this Lease
shall terminate, and Tenant shall remain liable as hereinafter provided. Upon such termination in writing of Tenant’s right to possession, Landlord shall have the right, subject to applicable Law, to re-enter the Premises and dispossess Tenant
and the legal representatives of Tenant and all other occupants of the Premises by unlawful detainer or other summary proceedings, or otherwise as permitted by Law, regain possession of the Premises and remove their property (including their trade
fixtures, personal property and those Tenant Additions which Tenant is required or permitted to remove under Article Twelve), but Landlord shall not be obligated to effect such removal, and such property may, at Landlord’s option, be stored
elsewhere, sold or otherwise dealt with as permitted by Law, at the risk of, expense of and for the account of Tenant, and the proceeds of any sale shall be applied pursuant to Law. Landlord shall in no event be responsible for the value,
preservation or safekeeping of any such property. Tenant hereby waives all claims for damages that may be caused by Landlord’s removing or storing Tenant’s personal property pursuant to this Section or Section 12.01, and Tenant hereby
indemnifies, and agrees to defend, protect and hold harmless, the Indemnitees from any and all loss, claims, demands, actions, expenses, liability and cost (including attorneys’ fees and expenses) arising out of or in any way related to such
removal or storage. Upon such written termination of Tenant’s right to possession and this Lease, Landlord shall have the right to recover damages for Tenant’s Default as provided herein or by Law, including the following damages provided
by California Civil Code Section 1951.2: 
  
 (1)
the worth at the time of award of the unpaid Rent which had been earned at the time of termination; 
  
 (2) the worth at the time of award of the amount by which the unpaid Rent which would have been earned after termination until the time of
award exceeds the amount of such Rent loss that Tenant proves could reasonably have been avoided; 
  
 (3) the worth at the time of award of the amount by which the unpaid Rent for the balance of the term of this Lease after the time of
award exceeds the amount of such Rent loss that Tenant proves could be reasonably avoided; and 
  
 (4) any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its
obligations under this Lease or which in the ordinary course 

  

 19 

 
of things would be likely to result therefrom. The word “rent” as used in this Section 11.02 shall have the same meaning as the defined term Rent
in this Lease. The “worth at the time of award” of the amount referred to in clauses (1) and (2) above is computed by allowing interest at the Default Rate. The worth at the time of award of the amount referred to in clause (3) above 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%). For the purpose of determining unpaid Rent under clause (3) above, the monthly Rent reserved in this
Lease shall be deemed to be the sum of the Monthly Base Rent, and monthly Storage Space Rent, if any, and the amounts last payable by Tenant as Rent Adjustments for the calendar year in which Landlord terminated this Lease as provided hereinabove.

  
 (c) Even if Tenant is in Default and/or has abandoned the
Premises, this Lease shall continue in effect for so long as Landlord does not terminate Tenant’s right to possession by written notice as provided in Section 11.02(b) above, and Landlord may enforce all its rights and remedies under this
Lease, including the right to recover Rent as it becomes due under this Lease. In such event, Landlord shall have all of the rights and remedies of a landlord under California Civil Code Section 1951.4 (lessor may continue Lease in effect after
Tenant’s Default and abandonment and recover Rent as it becomes due, if Tenant has the right to sublet or assign, subject only to reasonable limitations), or any successor statute. During such time as Tenant is in Default, if Landlord has not
terminated this Lease by written notice and if Tenant requests Landlord’s consent to an assignment of this Lease or a sublease of the Premises, subject to Landlord’s option to recapture pursuant to Section 10.02, Landlord shall not
unreasonably withhold its consent to such assignment or sublease. Tenant acknowledges and agrees that the provisions of Article Ten shall be deemed to constitute reasonable limitations of Tenant’s right to assign or sublet. Tenant acknowledges
and agrees that in the absence of written notice pursuant to Section 11.02(b) above terminating Tenant’s right to possession, no other act of Landlord shall constitute a termination of Tenant’s right to possession or an acceptance of
Tenant’s surrender of the Premises, including acts of maintenance or preservation or efforts to relet the Premises or the appointment of a receiver upon initiative of Landlord to protect Landlord’s interest under this Lease or the
withholding of consent to a subletting or assignment, or terminating a subletting or assignment, if in accordance with other provisions of this Lease. 
  
 (d) In the event that Landlord seeks an injunction with respect to a breach or threatened breach by Tenant of any of the covenants, conditions or
provisions of this Lease, Tenant agrees to pay the premium for any bond required in connection with such injunction. 
  
 (e) Tenant hereby waives any and all rights to relief from forfeiture, redemption or reinstatement granted by Law (including California Civil Code of
Procedure Sections 1174 and 1179) in the event of Tenant being evicted or dispossessed for any cause or in the event of Landlord obtaining possession of the Premises by reason of Tenant’s Default or otherwise; 
  
 (f) Notwithstanding any other provision of this Lease, a notice to Tenant
given under this Article and Article Twenty-four of this Lease or given pursuant to California Code of Civil Procedure Section 1161, and any notice served by mail shall be deemed served, and the requisite waiting period deemed to begin under said
Code of Civil Procedure Section upon mailing, without any additional waiting requirement under Code of Civil Procedure Section 1011 et seq. or by other Law. For purposes of Code of Civil Procedure Section 1162, Tenant’s “place of
residence”, “usual place of business”, “the property” and “the place where the property is situated” shall mean and be the Premises, whether or not Tenant has vacated same at the time of service. 
  
 (g) The voluntary or other surrender or termination of this Lease, or a
mutual termination or cancellation thereof, shall not work a merger and shall terminate all or any existing assignments, subleases, subtenancies or occupancies permitted by Tenant, except if and as otherwise specified in writing by Landlord.

  
 (h) No delay or omission in the exercise of any right or
remedy of Landlord upon any default by Tenant, and no exercise by Landlord of its rights pursuant to Section 26.15 to perform any duty which Tenant fails timely to perform, shall impair any right or remedy or be construed as a waiver. No provision
of this Lease shall be deemed waived by Landlord unless such waiver is in a writing signed by Landlord. The waiver by Landlord of any breach of any provision of this Lease shall not be deemed a waiver of any subsequent breach of the same or any
other provision of this Lease. 
  

	11.03	ATTORNEY’S FEES 

  
 In the event any party brings any suit or other proceeding with respect to the subject matter or enforcement of this Lease, the prevailing party (as determined by the court, agency or other authority before which such
suit or proceeding is commenced) shall, in addition to such other relief as may be awarded, be entitled to recover attorneys’ fees, expenses and costs of investigation as actually incurred, including court costs, expert witness fees, costs and
expenses of investigation, and all attorneys’ fees, costs and expenses in any such suit or proceeding (including in any action or participation in or in connection with any case or proceeding under the Bankruptcy Code, 11 United States Code
Sections 101 et seq., or any successor statutes, in establishing or enforcing the right to indemnification, in appellate proceedings, or in connection with the enforcement or collection of any judgment obtained in any such suit or
proceeding). 
  

	11.04	BANKRUPTCY 

  
 The following provisions shall apply in the event of the bankruptcy or insolvency of Tenant: 
  

 20 

 (a) In connection with any proceeding under Chapter 7 of the Bankruptcy Code where the trustee of Tenant
elects to assume this Lease for the purposes of assigning it, such election or assignment, may only be made upon compliance with the provisions of (b) and (c) below, which conditions Landlord and Tenant acknowledge to be commercially reasonable. In
the event the trustee elects to reject this Lease then Landlord shall immediately be entitled to possession of the Premises without further obligation to Tenant or the trustee. 
  
 (b) Any election to assume this Lease under Chapter 11 or 13 of the Bankruptcy Code by Tenant as debtor-in-possession or by
Tenant’s trustee (the “Electing Party”) must provide for: 
  
 The Electing Party to cure or provide to Landlord adequate assurance that it will cure all monetary defaults under this Lease within fifteen (15) days from the date of assumption and it will cure all nonmonetary
defaults under this Lease within thirty (30) days from the date of assumption. Landlord and Tenant acknowledge such condition to be commercially reasonable. 
  
 (c) If the Electing Party has assumed this Lease or elects to assign Tenant’s interest under this Lease to any other person, such interest may be
assigned only if the intended assignee has provided adequate assurance of future performance (as herein defined), of all of the obligations imposed on Tenant under this Lease. 
  
 For the purposes hereof, “adequate assurance of future performance” means that Landlord has ascertained that each
of the following conditions has been satisfied: 
  
 (i) The assignee has submitted a current financial statement, certified by its chief financial officer, which shows a net worth and working capital in amounts sufficient to assure the future performance by the assignee of Tenant’s
obligations under this Lease; and 
  
 (ii)
Landlord has obtained consents or waivers from any third parties which may be required under a lease, mortgage, financing arrangement, or other agreement by which Landlord is bound, to enable Landlord to permit such assignment. 
  
 (d) Landlord’s acceptance of rent or any other payment from any trustee,
receiver, assignee, person, or other entity will not be deemed to have waived, or waive, the requirement of Landlord’s consent, Landlord’s right to terminate this Lease for any transfer of Tenant’s interest under this Lease without
such consent, or Landlord’s claim for any amount of Rent due from Tenant. 
  
 11.05 LANDLORD’S DEFAULT 
  
 Landlord shall be in default hereunder
in the event Landlord has not begun and pursued with reasonable diligence the cure of any failure of Landlord to meet its obligations hereunder within thirty (30) days after the receipt by Landlord of written notice from Tenant of the alleged
failure to perform. In no event shall Tenant have the right to terminate or rescind this Lease as a result of Landlord’s default as to any covenant or agreement contained in this Lease. Tenant hereby waives such remedies of termination and
rescission and hereby agrees that Tenant’s remedies for default hereunder and for breach of any promise or inducement shall be limited to a suit for damages and/or injunction. In addition, Tenant hereby covenants that, prior to the exercise of
any such remedies, it will give Mortgagee notice and a reasonable time to cure any default by Landlord. 
  
 ARTICLE TWELVE 
 SURRENDER OF PREMISES 
  

	12.01	IN GENERAL 

  
 Upon the Termination Date, Tenant shall surrender and vacate the Premises immediately and deliver possession thereof to Landlord in (i) a clean, good and tenantable condition, ordinary wear and tear, and damage caused
by casualty (subject to the terms of Article 14) or by Landlord excepted, and (ii) full compliance with law, including without limitation, Tenant’s having delivered to Landlord (a) a Business Closure Report issued by the County of San Mateo
Department of Environmental Health, and if the County of San Mateo Department of Environmental Health does not then issue a “Business Closure Report”, Tenant shall have delivered to Landlord the equivalent confirmation of business closure
in compliance with Environmental Laws then issued by the County of San Mateo Department of Environmental Health; and (b) a Radioactive Material License Termination issued by the appropriate governmental authority if a radiation license (or
radioactive material license or similar permit with respect to radioactive material) was obtained from the applicable governmental authority for the Premises or any operation therein, or was required by Environmental Laws to be obtained, and if the
applicable governmental authority does not then issue a “Radioactive Material License Termination”, Tenant shall have delivered to Landlord the equivalent confirmation of closure of the site in compliance with Environmental Laws applicable
to radioactive material then issued by the applicable governmental authority. Tenant shall deliver to Landlord all keys to the Premises. Tenant shall remove from the Premises all movable personal property of Tenant and Tenant’s trade fixtures
(including without limitation, any autoclaves, hoods, animal facility, cold rooms, and generators, the costs of which were not paid for by any portion of Landlord’s Maximum Contribution), including, subject to Section 6.04, cabling for any of
the foregoing. Tenant shall be entitled to remove such Tenant Additions which at the time of their installation Landlord and Tenant agreed may be removed by Tenant. Tenant shall also remove any Tenant Additions containing Hazardous Material, but
Tenant shall not otherwise be required to remove Tenant Additions installed pursuant to Section 2.2 of Rider 2 of this Lease or Article Nine of this 

  

 21 

 
Lease unless, at the time Landlord was required to give its consent or objection to the proposed Tenant Additions, Landlord notified Tenant of those which
Landlord requires Tenant to remove upon expiration or earlier termination. Tenant immediately shall repair all damage resulting from removal of any of Tenant’s property, furnishings or Tenant Additions, shall close all floor, ceiling and roof
openings and shall restore the Premises to a tenantable condition as reasonably determined by Landlord. If any of the Tenant Additions which were installed by Tenant involved the lowering of ceilings, raising of floors or the installation of
specialized wall or floor coverings or lights, then Tenant shall also be obligated to return such surfaces to their condition prior to the commencement of this Lease. In the event possession of the Premises is not delivered to Landlord when required
hereunder, or if Tenant shall fail to remove those items described above, Landlord may (but shall not be obligated to), at Tenant’s expense, remove any of such property and store, sell or otherwise deal with such property as provided in Section
11.02(b), including the waiver and indemnity obligations provided in that Section, and undertake, at Tenant’s expense, such restoration work as Landlord deems necessary or advisable. 
  

	12.02	LANDLORD’S RIGHTS 

  
 All property which may be removed from the Premises by Landlord shall be conclusively presumed to have been abandoned by Tenant and Landlord may deal with such property as provided in Section 11.02(b), including the
waiver and indemnity obligations provided in that Section. Tenant shall also reimburse Landlord for all costs and expenses incurred by Landlord in removing any of Tenant Additions which Tenant was required to remove and in restoring the Premises to
the condition required by this Lease at the Termination Date. 
  
 ARTICLE THIRTEEN 
 HOLDING OVER 
  
 Tenant shall pay Landlord the greater of (i) double the monthly Rent payable for the month immediately preceding the holding over (including increases for Rent
Adjustments which Landlord may reasonably estimate) or, (ii) double the fair market rental value of the Premises as reasonably determined by Landlord for each month or portion thereof that Tenant retains possession of the Premises, or any portion
thereof, after the Termination Date (without reduction for any partial month that Tenant retains possession). Tenant shall also pay all damages sustained by Landlord by reason of such retention of possession. The provisions of this Article shall not
constitute a waiver by Landlord of any re-entry rights of Landlord and Tenant’s continued occupancy of the Premises shall be as a tenancy in sufferance. 
  
 ARTICLE FOURTEEN 
 DAMAGE BY FIRE OR OTHER
CASUALTY 
  

	14.01	SUBSTANTIAL UNTENANTABILITY 

  
 (a) If any fire or other casualty (whether insured or uninsured) renders all or a substantial portion of the Premises or the Building untenantable,
Landlord shall, with reasonable promptness after the occurrence of such damage, estimate the length of time that will be required to substantially complete the repair and restoration and shall by notice advise Tenant of such estimate
(“Landlord’s Notice”). If Landlord estimates that the amount of time required to substantially complete such repair and restoration will exceed one hundred eighty (180) days from the date such damage occurred, then Landlord, or Tenant
if all or a substantial portion of the Premises is rendered untenantable, shall have the right to terminate this Lease as of the date of such damage upon giving written notice to the other at any time within twenty (20) days after delivery of
Landlord’s Notice, provided that if Landlord so chooses, Landlord’s Notice may also constitute such notice of termination. 
  
 (b) In the event that the Building is damaged or destroyed to the extent of more than twenty-five percent (25%) of its replacement cost or to any extent
if no insurance proceeds or insufficient insurance proceeds are receivable by Landlord, or if the buildings at the Project shall be damaged to the extent of fifty percent (50%) or more of the replacement value or to any extent if no insurance
proceeds or insufficient insurance proceeds are receivable by Landlord, and regardless of whether or not the Premises be damaged, Landlord may elect by written notice to Tenant given within thirty (30) days after the occurrence of the casualty to
terminate this Lease in lieu of so restoring the Premises, in which event this Lease shall terminate as of the date specified in Landlord’s notice, which date shall be no later than sixty (60) days following the date of Landlord’s notice.

  
 (c) Unless this Lease is terminated as provided in the
preceding Subsections 14.01 (a) and (b), Landlord shall proceed with reasonable promptness to repair and restore the Premises to its condition as existed prior to such casualty, subject to reasonable delays for insurance adjustments and Force
Majeure delays, and also subject to zoning Laws and building codes then in effect. Landlord shall have no liability to Tenant, and Tenant shall not be entitled to terminate this Lease if such repairs and restoration are not in fact completed within
the time period estimated by Landlord so long as Landlord shall proceed with reasonable diligence to complete such repairs and restoration. 
  
 (d) Tenant acknowledges that Landlord shall be entitled to the full proceeds of any insurance coverage, whether carried by Landlord or Tenant, for damages
to the Premises, except for those proceeds of Tenant’s insurance of its own personal property and equipment which would be removable by Tenant at the Termination Date. All such insurance proceeds shall be payable to Landlord whether or not the
Premises are to be repaired and restored, provided, however, if this Lease is not terminated and the parties proceed to repair and restore Tenant Additions at Tenant’s cost, to the extent Landlord received proceeds of Tenant’s insurance
covering Tenant Additions, such proceeds shall be applied to reimburse Tenant for its cost of repairing and restoring Tenant Additions. 
  

 22 

 (e) Notwithstanding anything in this Article Fourteen to the contrary: (i) Landlord shall have no duty
pursuant to this Section to repair or restore any portion of any Tenant Additions or to expend for any repair or restoration of the Premises or Building amounts in excess of insurance proceeds paid to Landlord and available for repair or
restoration; and (ii) Tenant shall not have the right to terminate this Lease pursuant to this Section if any damage or destruction was caused by the act or neglect of Tenant, its agent or employees. Whether or not the Lease is terminated pursuant
to this Article Fourteen, in no event shall Tenant be entitled to any compensation or damages for loss of the use of the whole or any part of the Premises or for any inconvenience or annoyance occasioned by any such damage, destruction, rebuilding
or restoration of the Premises or the Building or access thereto. 
  
 (f) Any repair or restoration of the Premises performed by Tenant shall be in accordance with the provisions of Article Nine hereof. 
  

	14.02	INSUBSTANTIAL UNTENANTABILITY 

  
 Unless this Lease is terminated as provided in the preceding Subsections 14.01 (a) and (b), then Landlord shall proceed to repair and restore the Building or the Premises
other than Tenant Additions, with reasonable promptness, unless such damage is to the Premises and occurs during the last six (6) months of the Term, in which event either Tenant or Landlord shall have the right to terminate this Lease as of the
date of such casualty by giving written notice thereof to the other within twenty (20) days after the date of such casualty. Notwithstanding the foregoing, Landlord’s obligation to repair shall be limited in accordance with the provisions of
Section 14.01 above. 
  

	14.03	RENT ABATEMENT 

  
 Except for the negligence or willful act of Tenant or its agents, employees, contractors or invitees, if all or any part of the Premises are rendered untenantable by fire or other casualty and this Lease is not
terminated, Monthly Base Rent and Rent Adjustments shall abate for that part of the Premises which is untenantable on a per diem basis from the date of the casualty until Landlord has Substantially Completed the repair and restoration work in the
Premises which it is required to perform, provided, that as a result of such casualty, Tenant does not occupy the portion of the Premises which is untenantable during such period. 
  

	14.04	WAIVER OF STATUTORY REMEDIES 

  
 The provisions of this Lease, including this Article Fourteen, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or
destruction of, the Premises or the Property or any part of either, and any Law, including Sections 1932(2), 1933(4), 1941 and 1942 of the California Civil Code, with respect to any rights or obligations concerning damage or destruction shall have
no application to this Lease or to any damage to or destruction of all or any part of the Premises or the Property or any part of either, and are hereby waived. 
  

ARTICLE FIFTEEN 
 EMINENT DOMAIN 

 

	15.01	TAKING OF WHOLE OR SUBSTANTIAL PART 

  
 In the event the whole or any substantial part of the Building or of the Premises is taken or condemned by any competent authority for any public use or purpose
(including a deed given in lieu of condemnation) and is thereby rendered untenantable, this Lease shall terminate as of the date title vests in such authority or any earlier date on which possession is required to be surrendered to such authority,
and Monthly Base Rent and Rent Adjustments shall be apportioned as of the Termination Date. Further, if at least twenty-five percent (25%) of the rentable area of the Project is taken or condemned by any competent authority for any public use or
purpose (including a deed given in lieu of condemnation), and regardless of whether or not the Premises be so taken or condemned, Landlord may elect by written notice to Tenant to terminate this Lease as of the date title vests in such authority or
any earlier date on which possession is required to be surrendered to such authority, and Monthly Base Rent and Rent Adjustments shall be apportioned as of the Termination Date. Landlord may, without any obligation to Tenant, agree to sell or convey
to the taking authority the Premises, the Building, Tenant’s Phase, the Project or any portion thereof sought by the taking authority, free from this Lease and the right of Tenant hereunder, without first requiring that any action or proceeding
be instituted or, if instituted, pursued to a judgment. Notwithstanding anything to the contrary herein set forth, in the event the taking of the Building or Premises is temporary (for less than the remaining term of the Lease), Landlord may elect
either (i) to terminate this Lease or (ii) permit Tenant to receive the entire award attributable to the Premises in which case Tenant shall continue to pay Rent and this Lease shall not terminate.

reduce or increase, as the case may be, the Monthly Base Rent and Tenant’s Share to reflect the Rentable Area of the Premises or Building, as the case may be, remaining after any such taking or condemnation. Landlord, upon receipt and to the
extent of the award in condemnation (or proceeds of sale) shall make 

  

 23 

 
necessary repairs and restorations to the Premises (exclusive of Tenant Additions) and to the Building to the extent necessary to constitute the portion of
the Building not so taken or condemned as a complete architectural and economically efficient unit. Notwithstanding the foregoing, if as a result of any taking, or a governmental order that the grade of any street or alley adjacent to the Building
is to be changed and such taking or change of grade makes it necessary or desirable to substantially remodel or restore the Building or prevents the economical operation of the Building, Landlord shall have the right to terminate this Lease upon
ninety (90) days prior written notice to Tenant. 
  

	15.03	COMPENSATION 

  
 Landlord shall be entitled to receive the entire award (or sale proceeds) from any such taking, condemnation or sale without any payment to Tenant, and Tenant hereby assigns to Landlord Tenant’s interest, if any,
in such award; provided, however, Tenant shall have the right separately to pursue against the condemning authority a separate award in respect of the loss, if any, to Tenant Additions paid for by Tenant without any credit or allowance from
Landlord, for fixtures or personal property of Tenant, or for relocation or business interruption expenses, so long as there is no diminution of Landlord’s award as a result. 
  
 ARTICLE SIXTEEN

insurance shall be for a combined single limit of Five Million and No/100 Dollars ($5,000,000.00). Neither Landlord’s obligation to carry such insurance nor the carrying of such insurance shall be deemed to be an indemnity by Landlord with
respect to any claim, liability, loss, cost or expense due, in whole or in part, to Tenant’s negligent acts or omissions or willful misconduct. Without obligation to do so, Landlord may, in its sole discretion from time to time, carry insurance
in amounts greater and/or for coverage additional to the coverage and amounts set forth above. 
  

	16.04	WAIVER OF SUBROGATION 

  
 (a) Landlord agrees that, if obtainable at no, or minimal, additional cost, and so long as the same is permitted under the laws of the State of
California, it will include in its “All Risks” policies appropriate 

  

 24 

 
clauses pursuant to which the insurance companies (i) waive all right of subrogation against Tenant with respect to losses payable under such policies and/or
(ii) agree that such policies shall not be invalidated should the insured waive in writing prior to a loss any or all right of recovery against any party for losses covered by such policies.

carriers, have Landlord named in such policy or policies as an additional insured. If Landlord shall be named as an additional insured in accordance with the foregoing, Landlord agrees to endorse promptly to the order of Tenant, without recourse,
any check, draft, or order for the payment of money representing the proceeds of any such policy or representing any other payment growing out of or connected with said policies, and Landlord does hereby irrevocably waive any and all rights in and
to such proceeds and payments. 
  
 (c) Provided that
Landlord’s right of full recovery under its policy or policies aforesaid is not adversely affected or prejudiced thereby, Landlord hereby waives any and all right of recovery which it might otherwise have against Tenant, its servants, agents
and employees, for loss or damage occurring to the Real Property and the fixtures, appurtenances and equipment therein, to the extent the same is covered by Landlord’s insurance, notwithstanding that such loss or damage may result from the
negligence or fault of Tenant, its servants, agents or employees. Provided that Tenant’s right of full recovery under its aforesaid policy or policies is not adversely affected or prejudiced thereby, Tenant hereby waives any and all right of
recovery which it might otherwise have against Landlord, its servants, and employees and against every other tenant in the Real Property who shall have executed a similar waiver as set forth in this Section 16.04 (c) for loss or damage to Tenant
Additions, whether or not removable, and to Tenant’s furniture, furnishings, fixtures and other property removable by Tenant under the provisions hereof to the extent the same is covered or coverable by Tenant’s insurance required under
this Lease, notwithstanding that such loss or damage may result from the negligence or fault of Landlord, its servants, agents or employees, or such other tenant and the servants, agents or employees thereof. 
  
 (d) Landlord and Tenant hereby agree to advise the other promptly if the
clauses to be included in their respective insurance policies pursuant to subparagraphs (a) and (b) above cannot be obtained on the terms hereinbefore provided and thereafter to furnish the other with a certificate of insurance or copy of such
policies showing the naming of the other as an additional insured, as aforesaid. Landlord and Tenant hereby also agree to notify the other promptly of any cancellation or change of the terms of any such policy which would affect such clauses or
naming. All such policies which name both Landlord and Tenant as additional insureds shall, to the extent obtainable, contain agreements by the insurers to the effect that no act or omission of any additional insured will invalidate the policy as to
the other additional insureds. 
  

	16.05	NOTICE OF CASUALTY 

  
 Tenant shall give Landlord notice in case of a fire or accident in the Premises promptly after Tenant is aware of such event. 
  
 ARTICLE SEVENTEEN 
 WAIVER OF CLAIMS AND
INDEMNITY 
  

	17.01	WAIVER OF CLAIMS 

  
 To the extent permitted by Law, Tenant releases the Indemnitees from, and waives all claims for, damage to person or property sustained by the Tenant or any occupant of the Premises or the Property resulting directly
or indirectly from any existing or future condition, defect, matter or thing in and about the Premises or the Property or any part of either or any equipment or appurtenance therein, or resulting from any accident in or about the Premises or the
Property, or resulting directly or indirectly from any act or neglect of any tenant or occupant of the Property or of any other person, including Landlord’s agents and servants, except to the extent caused by the willful and wrongful act of any
of the Indemnitees. To the extent permitted by Law, Tenant hereby waives any consequential damages or claims for inconvenience or loss of business, rents, or profits as a result of such injury or damage, whether or not caused by the willful and
wrongful act of any of the Indemnitees. If any such damage, whether to the Premises or the Property or any part of either, or whether to Landlord or to other tenants in the Property, results from any act or neglect of Tenant, its employees,
servants, agents, contractors, invitees or customers, Tenant shall be liable therefor and Landlord may, at Landlord’s option, repair such damage and Tenant shall, upon demand by Landlord, as payment of additional Rent hereunder, reimburse
Landlord within ten (10) days of demand for the total cost of such repairs, in excess of amounts, if any, paid to Landlord under insurance covering such damages. Tenant shall not be liable for any such damage caused by its acts or neglect if
Landlord or a tenant has recovered the full amount of the damage from proceeds of insurance policies and the insurance company has waived its right of subrogation against Tenant. 
  

 25 

	17.02	INDEMNITY BY TENANT 

  
 To the extent permitted by Law, Tenant hereby indemnifies, and agrees to protect, defend and hold the Indemnitees harmless, against any and all actions, claims, demands, liability, costs and expenses, including
attorneys’ fees and expenses for the defense thereof, arising from Tenant’s occupancy of the Premises, from the undertaking of any Tenant Additions or repairs to the Premises, from the conduct of Tenant’s business on the Premises, or
from any breach or default on the part of Tenant in the performance of any covenant or agreement on the part of Tenant to be performed pursuant to the terms of this Lease, or from any willful act or negligence of Tenant, its agents, contractors,
servants, employees, customers or invitees, in or about the Premises or the Property or any part of either. In case of any action or proceeding brought against the Indemnitees by reason of any such claim, upon notice from Landlord, Tenant covenants
to defend such action or proceeding by counsel chosen by Landlord, in Landlord’s sole discretion. Landlord reserves the right to settle, compromise or dispose of any and all actions, claims and demands related to the foregoing indemnity. The
foregoing indemnity shall not operate to relieve Indemnitees of liability to the extent such liability is caused by the active negligence, and willful and wrongful act of Indemnitees. Further, the foregoing indemnity is subject to and shall not
diminish any waivers in effect in accordance with Section 16.04 by Landlord or its insurers to the extent of amounts, if any, paid to Landlord under its “All-Risks” property insurance.

dealt with any real estate broker, sales person, or finder in connection with this Lease, and no such person initiated or participated in the negotiation of this Lease. Tenant hereby indemnifies and agrees to protect, defend and hold Landlord and
Landlord’s Broker harmless from and against all claims, losses, damages, liability, costs and expenses (including, without limitation, attorneys’ fees and expenses) by virtue of any broker, agent or other person claiming a commission or
other form of compensation by virtue of alleged representation of, or dealings or discussions with, Tenant with respect to the subject matter of this Lease, except for Landlord’s Broker and except for a commission payable to Tenant’s

Landlord’s Broker and Tenant’s Broker, Landlord has not dealt with any real estate broker, sales person, or finder in connection with the subject matter of this Lease. Tenant is not obligated to pay or fund any amount to Landlord’s
Broker, and Landlord hereby agrees to pay such commission, if any, to which Landlord’s Broker is entitled in connection with the subject matter of this Lease pursuant to Landlord’s separate written agreement with Landlord’s Broker.
Landlord hereby indemnifies and agrees to protect, defend and hold Tenant harmless from and against all claims, losses, damages, liability, costs and expenses (including, without limitation, attorneys’ fees and expenses) by virtue of any
broker, agent or other person claiming a commission or other form of compensation by virtue of alleged representation of Landlord with respect to the transaction contemplated by this Lease. The provisions of this Section shall survive the expiration
or earlier termination of the Lease. 
  
 ARTICLE TWENTY-THREE

 MORTGAGEE PROTECTION 
  

	23.01	SUBORDINATION AND ATTORNMENT 

  
 (a) This Lease is and shall be expressly subject and subordinate at all times to (i) any ground or underlying lease of the Real Property, now or hereafter
existing, and all amendments, extensions, renewals and modifications to any such lease, and (ii) the lien of any mortgage or trust deed now or hereafter encumbering fee title to the Real Property and/or the leasehold estate under any such lease, and
all amendments, extensions, renewals, replacements and modifications of such mortgage or trust deed and/or the obligation secured thereby, unless such ground lease or ground lessor, or mortgage, trust deed or Mortgagee, expressly provides or elects
that the Lease shall be superior to such lease or mortgage or trust deed. If any such mortgage or trust deed is foreclosed (including any sale of the Real Property pursuant to a power of sale), or if any such lease is terminated, upon request of the
Mortgagee or ground lessor, as the case may be, Tenant shall attorn to the purchaser at the foreclosure sale or to the ground lessor under such lease, as the case may be, provided, however, that such purchaser or ground lessor shall not be (i) bound
by any payment of Rent for more than one month in advance except payments in the nature of security for the performance by Tenant of its obligations under this Lease; (ii) subject to any offset, defense or damages arising out of a default of any
obligations of any preceding Landlord; or (iii) bound by any amendment or modification of this Lease made without the written consent of the Mortgagee or ground lessor; or (iv) liable for any security deposits not actually received in cash by such
purchaser or ground lessor. This subordination shall be self-operative and no further certificate or instrument of subordination need be required by any such Mortgagee or ground lessor. In confirmation of such subordination, however, Tenant shall
execute promptly any reasonable certificate or instrument that Landlord, Mortgagee or ground lessor may request. Upon request by such successor in interest, Tenant shall execute and deliver reasonable instruments confirming the attornment provided
for herein. 
  

 27 

 (b) Notwithstanding any provision of the Lease to the contrary, provided that: (i) Tenant has executed
and delivered a subordination, non-disturbance and attornment agreement substantially in the form of Exhibit F hereto, with such changes thereto as any mortgagee, trustee, beneficiary or holder of other security interest
(“Mortgagee”) may reasonably require (“Non-disturbance Agreement”) and complies with the provisions thereof, and (ii) Tenant is not in default under this Lease, no foreclosure, sale pursuant to power of sale or conveyance by deed
in lieu of foreclosure shall affect Tenant’s rights under this Lease, except to the extent provided by such Non-Disturbance Agreement. If Tenant fails to execute and deliver any Non-disturbance Agreement within fifteen (15) days of a request
therefor from Landlord, Tenant hereby constitutes Landlord as Tenant’s attorney-in-fact to execute and deliver such instrument. Landlord’s inability to obtain the signature of any Mortgagee on any such Non-disturbance Agreement shall not
constitute a default by Landlord under this Lease, but so long as default by Tenant under this Lease is not the reason for Landlord’s inability to obtain such signature, any such lessor or Mortgagee shall be deemed to have elected that this
Lease be superior to the lease, mortgage or deed of trust in question, and Tenant shall, at the request of such lessor, mortgagee or beneficiary (or purchaser at any sale pursuant to the mortgage or deed of trust), attorn to any such party or enter
into a new lease with such party (as Landlord) for the balance of the Term then remaining hereunder upon the same terms and conditions as those herein. 
  

	23.02	MORTGAGEE PROTECTION 

  
 Tenant agrees to give any Mortgagee or ground lessor, by registered or certified mail, a copy of any notice of default served upon the Landlord by Tenant, provided that prior to such notice Tenant has received notice
(by way of service on Tenant of a copy of an assignment of rents and leases, or otherwise) of the address of such Mortgagee or ground lessor. Tenant further agrees that if Landlord shall have failed to cure such default within the time provided for
in this Lease, then the Mortgagee or ground lessor shall have an additional thirty (30) days after receipt of notice thereof within which to cure such default or if such default cannot be cured within that time, then such additional notice time as
may be necessary, if, within such thirty (30) days, any Mortgagee or ground lessor has commenced and is diligently pursuing the remedies necessary to cure such default (including commencement of foreclosure proceedings or other proceedings to
acquire possession of the Real Property, if necessary to effect such cure). Such period of time shall be extended by any period within which such Mortgagee or ground lessor is prevented from commencing or pursuing such foreclosure proceedings or
other proceedings to acquire possession of the Real Property by reason of Landlord’s bankruptcy. Until the time allowed as aforesaid for Mortgagee or ground lessor to cure such defaults has expired without cure, Tenant shall have no right to,
and shall not, terminate this Lease on account of default. This Lease may not be modified or amended so as to reduce the Rent or shorten the Term, or so as to adversely affect in any other respect to any material extent the rights of the Landlord,
nor shall this Lease be canceled or surrendered, without the prior written consent, in each instance, of the ground lessor or the Mortgagee. 
  
 ARTICLE TWENTY-FOUR 
 NOTICES 
  
 (a) All notices, demands or requests provided for or permitted to be given
pursuant to this Lease must be in writing and shall be personally delivered, sent by Federal Express or other reputable overnight courier service, or mailed by first class, registered or certified United States mail, return receipt requested,
postage prepaid. 
  
 (b) All notices, demands or requests to be
sent pursuant to this Lease shall be deemed to have been properly given or served by delivering or sending the same in accordance with this Section, addressed to the parties hereto at their respective addresses listed in Sections 1.01(2) and (3).

  
 (c) Notices, demands or requests sent by mail or overnight
courier service as described above shall be effective upon deposit in the mail or with such courier service. However, the time period in which a response to any such notice, demand or request must be given shall commence to run from (i) in the case
of delivery by mail, the date of receipt on the return receipt of the notice, demand or request by the addressee thereof, or (ii) in the case of delivery by Federal Express or other overnight courier service, the date of acceptance of delivery by an
employee, officer, director or partner of Landlord or Tenant. Rejection or other refusal to accept or the inability to deliver because of changed address of which no notice was given, as indicated by advice from Federal Express or other overnight
courier service or by mail return receipt, shall be deemed to be receipt of notice, demand or request sent. Notices may also be served by personal service upon any officer, director or partner of Landlord or Tenant, and shall be effective upon such
service. 
  
 (d) By giving to the other party at least thirty (30)
days written notice thereof, either party shall have the right from time to time during the term of this Lease to change their respective addresses for notices, statements, demands and requests, provided such new address shall be within the United
States of America. 
  
 ARTICLE TWENTY-FIVE 
 EXERCISE FACILITY 
  
 Tenant agrees to inform all employees of Tenant of the following: (i) the exercise facility is available for the use of the employees of tenants of the Project only and
for no other person; (ii) use of the facility is at the risk of Tenant or Tenant’s employees, and all users must sign a release; (iii) the facility is unsupervised; and (iv) users of the facility must report any needed equipment maintenance or
any unsafe conditions to the Landlord immediately. Landlord may discontinue providing such facility at Landlord’s sole option at any time without 

  

 28 

 
incurring any liability. As a condition to the use of the exercise facility, Tenant and each of Tenant’s employees that uses the exercise facility shall
first sign a written release in form and substance acceptable to Landlord. Landlord may change the rules and/or hours of the exercise facility at any time, and Landlord reserves the right to deny access to the exercise facility to anyone due to
misuse of the facility or noncompliance with rules and regulations of the facility. To the extent permitted by Law, Tenant hereby indemnifies, and agrees to protect, defend and hold the Indemnitees harmless, against any and all actions, claims,
demands, liability, costs and expenses, including attorneys’ fees and expenses for the defense thereof, arising from use of the exercise facility in the Project by Tenant, Tenant’s employees or invitees. In case of any action or proceeding
brought against the Indemnitees by reason of any such claim, upon notice from Landlord, Tenant covenants to defend such action or proceeding by counsel chosen by Landlord, in Landlord’s sole discretion. Landlord reserves the right to settle,
compromise or dispose of any and all actions, claims and demands related to the foregoing indemnity. 
  
 ARTICLE TWENTY-SIX 
 MISCELLANEOUS 
  

	26.01	LATE CHARGES 

  
 (a) All payments required hereunder (other than the Monthly Base Rent, Rent Adjustments, and Rent Adjustment Deposits, which shall be due as hereinbefore
provided) to Landlord shall be paid within ten (10) days after Landlord’s demand therefor. All such amounts (including Monthly Base Rent, Rent Adjustments, and Rent Adjustment Deposits) not paid when due shall bear interest from the date due
until the date paid at the Default Rate in effect on the date such payment was due. 
  
 (b) In the event Tenant is more than five (5) days late in paying any installment of Rent due under this Lease, Tenant shall pay Landlord a late charge equal to five percent (5%) of the delinquent installment of Rent.
The parties agree that (i) such delinquency will cause Landlord to incur costs and expenses not contemplated herein, the exact amount of which will be difficult to calculate, including the cost and expense that will be incurred by Landlord in
processing each delinquent payment of rent by Tenant, and (ii) the amount of such late charge represents a reasonable estimate of such costs and expenses and that such late charge shall be paid to Landlord for each delinquent payment in addition to
all Rent otherwise due hereunder. The parties further agree that the payment of late charges and the payment of interest provided for in subparagraph (a) above are distinct and separate from one another in that the payment of interest is to
compensate Landlord for its inability to use the money improperly withheld by Tenant, while the payment of late charges is to compensate Landlord for its additional administrative expenses in handling and processing delinquent payments. 

 
 (c) Payment of interest at the Default Rate and/or of late charges shall
not excuse or cure any default by Tenant under this Lease, nor shall the foregoing provisions of this Article or any such payments prevent Landlord from exercising any right or remedy available to Landlord upon Tenant’s failure to pay Rent when
due, including the right to terminate this Lease. 
  

	26.02	NO JURY TRIAL; VENUE; JURISDICTION 

  
 Each party hereto (which includes any assignee, successor, heir or personal representative of a party) shall not seek a jury trial, hereby waives trial by jury, and
hereby further waives any objection to venue in the County in which the Project is located, and agrees and consents to personal jurisdiction of the courts of the State of California, in any action or proceeding or counterclaim brought by any party
hereto against the other on any matter whatsoever arising out of or in any way connected with this Lease, the relationship of Landlord and Tenant, Tenant’s use or occupancy of the Premises, or any claim of injury or damage, or the enforcement
of any remedy under any statute, emergency or otherwise, whether any of the foregoing is based on this Lease or on tort law. No party will seek to consolidate any such action in which a jury has been waived with any other action in which a jury
trial cannot or has not been waived. It is the intention of the parties that these provisions shall be subject to no exceptions. By execution of this Lease the parties agree that this provision may be filed by any party hereto with the clerk or
judge before whom any action is instituted, which filing shall constitute the written consent to a waiver of jury trial pursuant to and in accordance with Section 631 of the California Code of Civil Procedure. No party has in any way agreed with or
represented to any other party that the provisions of this Section will not be fully enforced in all instances. The provisions of this Section shall survive the expiration or earlier termination of this Lease. 
  

	26.03	DEFAULT UNDER OTHER LEASE 

  
 It shall be a Default under this Lease if Tenant or any Affiliate holding any other lease with Landlord for premises in the Building defaults under such lease and as a result thereof such lease is terminated or
terminable. 
  

	26.04	OPTION 

  
 This Lease shall not become effective as a lease or otherwise until executed and delivered by both Landlord and Tenant. The submission of the Lease to Tenant does not constitute a reservation of or option for the
Premises, but when executed by Tenant and delivered to Landlord, the Lease shall constitute an irrevocable offer by Tenant in effect for fifteen (15) days to lease the Premises on the terms and conditions herein contained. 
  

 29 

	26.05	TENANT AUTHORITY 

  
 Tenant represents and warrants to Landlord that it has full authority and power to enter into and perform its obligations under this Lease, that the person executing this Lease is fully empowered to do so, and that no
consent or authorization is necessary from any third party. Landlord may request that Tenant provide Landlord evidence of Tenant’s authority. 
  

	26.06	ENTIRE AGREEMENT 

  
 This Lease, the Exhibits and Rider 2 attached hereto contain the entire agreement between Landlord and Tenant concerning the Premises and there are no other agreements, either oral or written, and no other
representations or statements, either oral or written, on which Tenant has relied. This Lease shall not be modified except by a writing executed by Landlord and Tenant. 
  
 26.07 MODIFICATION OF LEASE FOR BENEFIT OF MORTGAGEE 
  
 If Mortgagee of Landlord requires a modification of this Lease which shall not result in any increased cost or expense to Tenant or in any
other substantial and adverse change in the rights and obligations of Tenant hereunder, then Tenant agrees that the Lease may be so modified. 
  

	26.08	EXCULPATION 

  
 Tenant agrees, on its behalf and on behalf of its successors and assigns, that any liability or obligation under this Lease shall only be enforced against Landlord’s equity interest in the Property up to a
maximum of Five Million Dollars ($5,000,000.00) and in no event against any other assets of the Landlord, or Landlord’s officers or directors or partners, and that any liability of Landlord with respect to this Lease shall be so limited and
Tenant shall not be entitled to any judgment in excess of such amount. 
  

	26.09	ACCORD AND SATISFACTION 

  
 No payment by Tenant or receipt by Landlord of a lesser amount than any installment or payment of Rent due shall be deemed to be other than on account of the amount due, and no endorsement or statement on any check or
any letter accompanying any check or payment of Rent shall be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such installment or payment of Rent
or pursue any other remedies available to Landlord. No receipt of money by Landlord from Tenant after the termination of this Lease or Tenant’s right of possession of the Premises shall reinstate, continue or extend the Term. Receipt or
acceptance of payment from anyone other than Tenant, including an assignee of Tenant, is not a waiver of any breach of Article Ten, and Landlord may accept such payment on account of the amount due without prejudice to Landlord’s right to
pursue any remedies available to Landlord. 
  

	26.10	LANDLORD’S OBLIGATIONS ON SALE OF BUILDING 

  
 In the event of any sale or other transfer of the Building, Landlord shall be entirely freed and relieved of all agreements and obligations of Landlord hereunder accruing
or to be performed after the date of such sale or transfer, and any remaining liability of Landlord with respect to this Lease shall be limited to the dollar amount specified in Section 26.08 and Tenant shall not be entitled to any judgment in
excess of such amount. 
  

	26.11	BINDING EFFECT 

  
 Subject to the provisions of Article Ten, this Lease shall be binding upon and inure to the benefit of Landlord and Tenant and their respective heirs, legal representatives, successors and permitted assigns.

  

	26.12	CAPTIONS 

  
 The Article and Section captions in this Lease are inserted only as a matter of convenience and in no way define, limit, construe, or describe the scope or intent of such Articles and Sections. 
  

	26.13	TIME; APPLICABLE LAW; CONSTRUCTION 

  
 Time is of the essence of this Lease and each and all of its provisions. This Lease shall be construed in accordance with the Laws of the State of California. If more
than one person signs this Lease as Tenant, the obligations hereunder imposed shall be joint and several. If any term, covenant or condition of this Lease or the application thereof to any person or circumstance shall, to any extent, be invalid or
unenforceable, the remainder of this Lease, or the application of such term, covenant or condition to persons or circumstances other than those as to which it is held invalid or unenforceable, shall not be affected thereby and each item, covenant or
condition of this Lease shall be valid and be enforced to the fullest extent permitted by Law. Wherever the term “including” or “includes” is used in this Lease, it shall have the same meaning as if followed by the phrase
“but not limited to”. The language in all parts of this Lease shall be construed according to its normal and usual meaning and not strictly for or against either Landlord or Tenant. 
  

	26.14	ABANDONMENT 

  
 In the event Tenant vacates or abandons the Premises but is otherwise in compliance with all the terms, covenants and conditions of this Lease, Landlord shall (i) have the right to enter into the Premises in order to

  

 30 

 
show the space to prospective tenants, (ii) have the right to reduce the services provided to Tenant pursuant to the terms of this Lease to such levels as
Landlord reasonably determines to be adequate services for an unoccupied premises and (iii) during the last six (6) months of the Term, have the right to prepare the Premises for occupancy by another tenant upon the end of the Term. Tenant expressly
acknowledges that in the absence of written notice pursuant to Section 11.02(b) or pursuant to California Civil Code Section 1951.3 terminating Tenant’s right to possession, none of the foregoing acts of Landlord or any other act of Landlord
shall constitute a termination of Tenant’s right to possession or an acceptance of Tenant’s surrender of the Premises, and the Lease shall continue in effect. 
  

	26.15	LANDLORD’S RIGHT TO PERFORM TENANT’S DUTIES 

  
 If Tenant fails timely to perform any of its duties under this Lease, Landlord shall have the right (but not the obligation), to perform such duty on behalf and at the
expense of Tenant without prior notice to Tenant, and all sums expended or expenses incurred by Landlord in performing such duty shall be deemed to be additional Rent under this Lease and shall be due and payable upon demand by Landlord. 

 

	26.16	SECURITY SYSTEM 

  
 Landlord shall not be obligated to provide or maintain any security patrol or security system. Landlord shall not be responsible for the quality of any such patrol or system which may be provided hereunder or for
damage or injury to Tenant, its employees, invitees or others due to the failure, action or inaction of such patrol or system. 
  

	26.17	NO LIGHT, AIR OR VIEW EASEMENTS 

  
 Any diminution or shutting off of light, air or view by any structure which may be erected on lands of or adjacent to the Project shall in no way affect this Lease or
impose any liability on Landlord. 
  

	26.18	RECORDATION 

  
 Neither this Lease, nor any notice nor memorandum regarding the terms hereof, shall be recorded by Tenant. Any such unauthorized recording shall be a Default for which there shall be no cure or grace period. Tenant

	26.19	SURVIVAL 

  
 The waivers of the right of jury trial, the other waivers of claims or rights, the releases and the obligations of Tenant under this Lease to indemnify, protect, defend and hold harmless Landlord and/or Indemnitees

 Exhibit F - Page 1 

 THIS SUBORDINATION, NONDISTURBANCE AND ATTORNMENT AGREEMENT (the “Agreement”) is made by
and among Tenant, Landlord, and Beneficiary and affects the Property described in Exhibit A. Certain terms used in this Agreement are defined in the Defined Terms. This Agreement is entered into as of the Execution Date with reference to the
following facts: 
  
 A. Landlord and Tenant have entered into the
Lease covering certain space in the improvements located in and upon the Property (the “Premises”). 
  
 B. Beneficiary has made or is making the Loan to Landlord evidenced by the Note. The Note is secured, among other documents, by the Deed of Trust.

  
 C. Landlord, Tenant and Beneficiary all wish to subordinate
the Lease to the lien of the Deed of Trust. 
  
 D. Tenant has
requested that Beneficiary agree not to disturb Tenant’s rights in the Premises pursuant to the Lease in the event Beneficiary forecloses the Deed of Trust, or acquires the Property pursuant to the trustee’s power of sale contained in the
Deed of Trust or receives a transfer of the Property by a conveyance in lieu of foreclosure of the Property (collectively, a “Foreclosure Sale”) but only if Tenant is not then in default under the Lease and Tenant attorns to Beneficiary or
a third party purchaser at the Foreclosure Sale (a “Foreclosure Purchaser”). 
  
 NOW THEREFORE, in consideration of the premises and the mutual covenants contained herein, the parties agree as follows: 
  
 1. Subordination. The Lease and the leasehold estate created by the Lease and all of Tenant’s rights under the Lease are and shall remain
subordinate to the Deed of Trust and the lien of the Deed of Trust, to all rights of Beneficiary under the Deed of Trust and to all renewals, amendments, modifications and extensions of the Deed of Trust. 
  
 2. Acknowledgments by Tenant. Tenant agrees that: (a) Tenant has
notice that the Lease and the rent and all other sums due under the Lease have been or are to be assigned to Beneficiary as security for the Loan. In the event that Beneficiary notifies Tenant of a default under the Deed of Trust and requests Tenant
to pay its rent and all other sums due under the Lease to Beneficiary, Tenant shall pay such sums directly to Beneficiary or as Beneficiary may otherwise request. (b) Tenant shall send a copy of any notice or statement under the Lease to Beneficiary
at the same time Tenant sends such notice or statement to Landlord. (c) This Agreement satisfies any condition or requirement in the Lease relating to the granting of a nondisturbance agreement. 
  
 3. Foreclosure and Sale. In the event of a Foreclosure Sale,

  
 (a) So long as Tenant complies with this
Agreement and is not in default under any of the provisions of the Lease, the Lease shall continue in full force and effect as a direct lease between Beneficiary and Tenant, and Beneficiary will not disturb the possession of Tenant, subject to this
Agreement. Tenant agrees to attorn to and accept Beneficiary as landlord under the Lease and to be bound by and perform all of the obligations imposed by the Lease. Upon Beneficiary’s acquisition of title to the Property, Beneficiary will
perform all of the obligations imposed on the Landlord by the Lease except as set forth in this Agreement; provided, however, that Beneficiary shall not be: (i) liable for any act or omission of a prior landlord (including Landlord); or (ii) subject
to any offsets or defenses that Tenant might have against any prior landlord (including Landlord); or (iii) bound by any rent or additional rent which Tenant might have paid in advance to any prior landlord (including Landlord) for a period in
excess of one month or by any security deposit, cleaning deposit or other sum that Tenant may have paid in advance to any prior landlord (including Landlord); or (iv) bound by any amendment, modification, assignment or termination of the Lease made
without the written consent of Beneficiary; (v) obligated or liable with respect to any representations, warranties or indemnities contained in the Lease; or (vi) liable to Tenant or any other party for any conflict between the provisions of the
Lease and the provisions of any other lease affecting the Property which is not entered into by Beneficiary. 
  
 (b) Upon the written request of Beneficiary after a Foreclosure Sale, the parties shall execute a lease of the Premises upon the same
provisions as contained in the Lease between Landlord and Tenant, except as set forth in this Agreement, for the unexpired term of the Lease. 
  
 4. Subordination and Release of Purchase Options. Tenant represents that it has no right or option of any nature to purchase the Property or any
portion of the Property or any interest in the Borrower. To the extent Tenant has or acquires any such right or option, these rights or options are acknowledged to be subject and subordinate to the Mortgage and are waived and released as to
Beneficiary and any Foreclosure Purchaser. 
  
 5.
Acknowledgment by Landlord. In the event of a default under the Deed of Trust, at the election of Beneficiary, Tenant shall and is directed to pay all rent and all other sums due under the Lease to Beneficiary. 
  
 6. Construction of Improvements. Beneficiary shall not have any
obligation or incur any liability with respect to the completion of the improvements in which the Premises are located at the commencement of the term of the Lease. 
  

 Exhibit F - Page 2 

 7. Notice. All notices under this Agreement shall be deemed to have been properly given if
delivered by overnight courier service or mailed by United States certified mail, with return receipt requested, postage prepaid to the party receiving the notice at its address set forth in the Defined Terms (or at such other address as shall be
given in writing by such party to the other parties) and shall be deemed complete upon receipt or refusal of delivery. 
  
 8. Miscellaneous. Beneficiary shall not be subject to any provision of the Lease that is inconsistent with this Agreement. Nothing contained in
this Agreement shall be construed to derogate from or in any way impair or affect the lien or the provisions of the Deed of Trust. This Agreement shall be governed by and construed in accordance with the laws of the State of in which the Property is
located. 
  
 9. Liability and Successors and Assigns. In
the event that Beneficiary acquires title to the Premises or the Property, Beneficiary shall have no obligation nor incur any liability beyond Beneficiary’s then equity interest in the building in which the Premises is located up to a maximum
of Five Million Dollars ($5,000,000), and Tenant shall look solely to such equity interest (as limited) for the payment and performance of any obligations imposed upon Beneficiary under this Agreement or under the Lease. This Agreement shall run
with the land and shall inure to the benefit of the parties and, their respective successors and permitted assigns including a Foreclosure Purchaser. If a Foreclosure Purchaser acquires the Property or if Beneficiary assigns or transfers its
interest in the Note and Deed of Trust or the Property, all obligations and liabilities of Beneficiary under this Agreement shall terminate and be the responsibility of the Foreclosure Purchaser or other party to whom Beneficiary’s interest is
assigned or transferred. The interest of Tenant under this Agreement may not be assigned or transferred except in connection with an assignment of its interest in the Lease which has been consented to by Beneficiary. 
  
 IN WITNESS WHEREOF, the parties have executed this Subordination,
Nondisturbance and Attornment Agreement as of the Execution Date. 
  

			
	NOTICE:	    	THIS SUBORDINATION, NONDISTURBANCE AND ATTORNMENT AGREEMENT CONTAINS PROVISIONS WHICH ALLOW THE PERSON OBLIGATED ON THE LEASE TO OBTAIN A LOAN, A PORTION OF WHICH MAY BE EXPENDED FOR OTHER
PURPOSES THAN IMPROVEMENT OF THE PROPERTY.

 RIDER 2 
 ADDITIONAL PROVISIONS 
  
 This
Rider 2 (“Rider”) is attached to and a part of a certain Lease dated as of December 15, 2004 executed concurrently herewith by Metropolitan Life Insurance Company, a New York corporation, as Landlord, and Maxygen, Inc., a Delaware
corporation (for purposes of this Rider, “Maxygen” or “Tenant”), as Tenant, for the Premises as described therein (the “Lease”). 
  

SECTION 1. DEFINED TERMS; FORCE AND EFFECT 
  
 Capitalized terms used in this Rider shall have the same meanings set forth in the Lease except as otherwise specified herein and except for terms capitalized in the
ordinary course of punctuation. This Rider forms a part of the Lease, and a default by any party hereunder shall be a default under the Lease. Should any inconsistency arise between this Rider and any other provision of the Lease as to the specific
matters which are the subject of this Rider, the terms and conditions of this Rider shall control. 
  

	SECTION	2. PREMISES LEASED “AS-IS”; DELIVERY; COMMENCEMENT DATE; AND CONSTRUCTION 

  
 2.1. AS-IS; Delivery; Commencement Date. Notwithstanding any provision of the Lease to the contrary: 
  
 (a) AS-IS. Tenant acknowledges and agrees that (i) Tenant has been
afforded ample opportunity to inspect the Premises, the Building and the Project, and has investigated their condition to the extent Tenant desires to do so; (ii) Tenant hereby agrees that this Lease is of the Premises in its “AS IS”
condition; (iii) no representation regarding the condition of the Premises or the Building or the Project has been made by or on behalf of Landlord; (iv) Landlord has no obligation to remodel or to make any repairs, alterations or improvements to
the Premises, Building or the Project in connection with Tenant’s initial occupancy or provide Tenant any allowance for any work by Tenant, except for the Landlord Maximum Contribution as provided below; and (v) there is no Workletter for this
Lease. 
  
 (b) Delivery & Commencement Date. Possession
will be adequately tendered to Tenant by Landlord either delivering the keys (or other means of access) to Tenant or Tenant’s Broker, or by Landlord giving written notice that the keys (or other means of access) to the Premises are available
for Tenant or its representative to pick up at the office of Landlord or of the Seaport Centre Property Manager. Landlord shall tender to Tenant possession of the Premises no later than two (2) business days after execution of this Lease (the
“Projected Delivery Date”). On the date Landlord actually tenders to Tenant possession of the Premises (the “Delivery Date”), the Premises shall be subject to, and Tenant shall observe and perform, all the conditions and
covenants applicable to Tenant under this Lease, except as otherwise expressly provided in this Rider. During the period (the “Construction Period”) from the Delivery Date until the Commencement Date (defined below), in recognition of
Tenant’s construction and installations in, and preparation of, the Premises for the use and occupancy permitted by this Lease, Tenant shall not be obligated to pay Monthly Base Rent, Rent Adjustment Deposits or Rent Adjustments. The Term of
this Lease shall be as provided in Section 1.01(5) of the Basic Lease Provisions and shall commence on the date specified in Section 1.01(6) of the Basic Lease Provisions as the Projected Commencement Date, which same date shall be the Commencement
Date of the Term, except as provided in Subsection (c) below with respect to late delivery. 
  
 (c) Delay in Delivery. If Landlord does not tender possession of the Premises by the Projected Delivery Date by reason of the following: (i) the holding over or retention of possession of any tenant, tenants or
occupants or (ii) for any other reason, then Landlord shall not be subject to any liability for the failure to give possession on said date. In the event the Delivery Date does not occur until after January 4, 2005, the Commencement Date (instead of
occurring on the Projected Commencement Date) shall be delayed by a number of days equal to the days of delay after January 4, 2005 in Landlord’s delivery of possession to Tenant. No such failure to give possession shall affect the validity of
this Lease or the obligations of the Tenant hereunder. Within thirty (30) days following the occurrence of the Commencement Date, Landlord and Tenant shall enter into an agreement (which is attached to this Lease as Rider 1) confirming the
Commencement Date and the Expiration Date. If Tenant fails to enter into such agreement, then the Commencement Date and the Expiration Date shall be the dates designated by Landlord in such agreement. 
  
 2.2. Tenant Work Generally. Landlord and Tenant acknowledge and agree
that notwithstanding any provisions of the Lease to the contrary: (a) Tenant desires to do certain remodeling, repair, improvement or alteration in connection with its initial occupancy, which for purposes of this Lease is referred to as the Tenant
Work; (b) all Tenant Work, if any, shall be done as Tenant Alterations within the meaning of Article Nine of the Lease, subject to and in compliance with all conditions and provisions of the Lease applicable to Tenant Alterations, except as
otherwise expressly provided in this Rider; (c) without limiting the generality of any provisions of Article Nine, Tenant’s selection of Tenant’s space planner and/or architect and Tenant’s selection of contractor(s) shall be subject
to Landlord’s prior written approval, which shall not unreasonably be withheld; (d) if the Tenant Work does not exceed the amount of Landlord’s Maximum Contribution, Tenant shall not be required to obtain a completion and lien indemnity
bond for it; (e) such work, including all design, plan review, obtaining all approvals and permits, and construction shall be at Tenant’s sole cost and expense, 

  

 Rider 2 - Page 1 of 4 

 
including delivery to Landlord of plans and specifications of such Tenant Work (including 3 sets of as-built plans and specifications upon completion) to the
extent such work is more than recarpeting and/or repainting, and (f) Tenant shall pay Landlord a fee for monitoring such design, construction and work by Tenant which shall not exceed two percent of all “hard costs” of the Tenant Work.

  
 2.3. Design & Construction Responsibility for any
Tenant Work. Tenant shall be responsible for the suitability for the Tenant’s needs and business of the design and function of all Tenant Work and for its construction in compliance with all Law as applicable and as interpreted at the time
of construction of the Tenant Work, including all building codes and the ADA (as defined in the Lease). Tenant, through its architects and/or space planners (“Tenant’s Architect”), shall prepare all architectural plans and
specifications, and engineering plans and specifications, for the real property improvements to be constructed by Tenant in the Premises in sufficient detail to be submitted for approval by Landlord to the extent required pursuant to Article Nine of
the Lease and to be submitted by Tenant for governmental approvals and building permits and to serve as the detailed construction drawings and specifications for the contractor, and shall include, among other things, all partitions, doors, heating,
ventilating and air conditioning installation and distribution, ceiling systems, light fixtures, plumbing installations, electrical installations and outlets, telephone installations and outlets, any other installations required by Tenant, fire and
life-safety systems, wall finishes and floor coverings, whether to be newly installed or requiring changes from the as-is condition of the Premises as of the date of execution of the Lease. Tenant shall be responsible for the oversight, supervision
and construction of all Tenant Work in compliance with this Lease, including compliance with all Law as applicable and as interpreted at the time of construction, including all building codes and the ADA. 
  
 2.4. Landlord’s Maximum Contribution: Amount; Reimbursable Costs
& Payment. Landlord’s Maximum Contribution means an amount up to a maximum of One Hundred Thousand Dollars ($100,000.00) to reimburse Tenant for the actual costs of design, plan review, obtaining all approvals and permits, and
construction of Tenant Work in the Premises, and shall be payable as provided below. In no event shall the Landlord’s Maximum Contribution be used to reimburse any costs of designing, procuring or installing in the Premises any trade fixtures,
movable equipment, furniture, furnishings, telephone equipment, cabling for any of the foregoing, or other personal property (collectively “Personal Property” for purposes of this Rider), and the cost of such Personal Property shall be
paid by Tenant. Landlord’s Maximum Contribution shall be paid to Tenant within 30 days after the later of final completion of the Tenant Work and Landlord’s receipt of (i) a certificate of occupancy (if applicable), (ii) final as-built
plans and specifications, (iii) full, final, unconditional lien releases, and (iv) reasonable substantiation of costs incurred by Tenant with respect to the Tenant Work. Tenant must prior to expiration of six months after the Commencement Date
submit written application with the items required above for disbursement or reimbursement for any reimbursable costs out of the Landlord’s Maximum Contribution, and to the extent of any funds for which application has not been made prior to
that date or if and to the extent that the reimbursable costs of the Tenant Work are less than the amount of Landlord’s Maximum Contribution, then Landlord shall retain the unapplied or unused balance of the Landlord’s Maximum Contribution
and shall have no obligation or liability to Tenant with respect to such excess. 
  
 SECTION 3. OPTION TO EXTEND 
  
 (a) Landlord hereby
grants Tenant a single option to extend the initial Term of the Lease for an additional period of one (1) year (such period may be referred to as the “Option Term”), as to the entire Premises as it may then exist, upon and subject to the
terms and conditions of this Section (the “Option To Extend”), and provided that at the time of exercise of such right: (i) Tenant must be in occupancy of the entire Premises; (ii) so long as Landlord hereunder is also the landlord under
that certain lease to Tenant of all of Building 7 (515 Galveston Drive), Tenant then has all of Building 7 under lease from Landlord, Tenant is in occupancy of all of Building 7 and Tenant has duly exercised the option to extend such lease in
accordance with its terms; and (iii) Tenant then has a liquid net worth of no less than Seventy-five Million Dollars ($75,000,000.00), and such determination of liquid net worth shall count as assets of Tenant only cash, cash equivalents and liquid
investments, and such determination shall be certified by Tenant’s Chief Financial Officer, and supported by Tenant’s financial statements, copies of which shall be delivered to Landlord with Tenant’s written notice exercising its
right hereunder. Such supporting financial statements to be delivered to Landlord shall consist of Tenant’s audited financial statements for the most-recent, completed fiscal year, and Tenant’s financial statements for all fiscal quarters
completed after the end of the most-recent, completed fiscal year and before the date of Tenant’s Election Notice, with the financial statements for the most-recent, completed quarter certified by Tenant’s Chief Financial Officer.

  
 (b) Tenant’s election (the “Election Notice”)
to exercise the Option To Extend must be given to Landlord in writing no earlier than the date which is nine months (9) months before the Expiration Date and no later than the date which is six (6) months before the Expiration Date. If Tenant either
fails or elects not to exercise its Option to Extend by not timely giving its Election Notice, then the Option to Extend shall be null and void. 
  
 (c) The Option Term shall commence immediately after the expiration of the initial Term of the Lease. Tenant’s leasing of the Premises during the
Option Term shall be upon and subject to the same terms and conditions contained in the Lease except that (i) the Monthly Base Rent for the Premises hereunder shall increase to a monthly rate equal to One and 6/100 Dollars ($1.06) per square foot of
Rentable Area of the Premises for the Option Term, and Tenant shall continue to pay Tenant’s Share of Operating Expenses pursuant to the Lease (along with all expenses paid directly by Tenant to the utility or service provider, which direct
payments shall continue to be Tenant’s obligation); (ii) Tenant shall accept the Premises in its “AS-IS” condition without any obligation of Landlord to repaint, remodel, repair, improve or alter the Premises or to provide Tenant any
allowance therefor; and (iii) there shall be no further option or right to extend the term of the Lease. If Tenant timely and properly exercises the Option To Extend, references in the Lease to the Term shall be deemed to mean the initial Term as
extended by the Option Term unless the context clearly requires otherwise.
