Terms Defined. The following terms have the meanings set forth below. Certain other terms have the meanings set forth in the Basic Lease Information or elsewhere in this Lease. 

“Alterations”: Alterations, additions or other improvements to the Premises made by or on behalf of Tenant (but not including
the alterations, additions or other improvements, if any, made by or on behalf of Tenant during the initial improvement of the Premises pursuant to and governed by the provisions of the Work Letter attached hereto as Exhibit C). 

“Base Building”: The envelope of the Building (including all elements of the Building that make it watertight, such as the
foundation, roof, exterior walls, exterior doors, and exterior windows (collectively, the “building envelope”)), the structural portions of the Building, elevators, and exit stairwells and the Building Systems installed prior to the
Lease Date and located in the internal core of the Building. 
 “Building”: The office building consisting of a three story
office tower located on the Land, and commonly known as 6455 Christie Avenue, Emeryville, California.  

“Environmental Laws”: All Requirements relating to the environment, health and safety, or the use, generation,
handling, emission, release, discharge, storage or disposal of Hazardous Materials. 
 “Escalation Rent”: Tenant’s
Percentage Share of the Operating Expenses and Real Estate Taxes, allocable to each calendar year, or part thereof. If the Building or the Project is less than one hundred percent (100%) occupied during any part of any year, Landlord shall make an
appropriate adjustment of the variable components of Operating Expenses and Real Estate Taxes for that year, as reasonably determined by Landlord using sound accounting and management principles, to determine the amount of Operating Expenses and
Real Estate Taxes that would have been incurred during such year if the Building (or the Project, as the case may be) had been one hundred percent (100%) occupied during the entire year (and, if applicable, if the tenant improvements in the Building
had been fully constructed and the Land, the Building, the Project, and all tenant improvements in the Building and the Project had been fully assessed for Real Estate Tax purposes); provided that such adjusted amount shall not exceed the actual
Operating Expenses and Real Estate Taxes that Landlord reasonably expects to incur during such part of any year. Such adjusted amount shall be deemed to be the amount of Operating Expenses and Real Estate Taxes for that year. For purposes hereof,
“variable components” include only those component expenses that are affected by variations in occupancy levels. In no event shall Landlord collect more than one hundred percent (100%) of the Operating Expenses and Real Estate Taxes
for the Building and the Project. Landlord shall not make a profit on collecting Escalation Rent. 












 “Hazardous Materials”: Petroleum, asbestos, polychlorinated
biphenyls, radioactive materials, radon gas, mold, or any chemical, material or substance now or hereafter defined as or included in the definition of “hazardous substances,” “hazardous wastes,” “hazardous materials,”

“Impositions”: Taxes, assessments, charges, excises and levies, business taxes, licenses, permits, inspection and other
authorization fees, transit development fees, assessments or charges for housing funds, service payments in lieu of taxes and any other fees or charges of any kind at any time levied, assessed, charged or imposed by any federal, state or local

(iv) upon this Lease transaction, or any document to which Tenant is a party creating or transferring any interest or estate in the Premises; or (v) to the extent not included in Operating Expenses, an equitable prorata share of costs,
fees and other expenses incurred in connection with providing transportation services as provided by the Owner Participation Agreement, as amended, affecting the Project. Impositions do not include Real Estate Taxes, franchise, transfer, inheritance
or capital stock taxes, or income taxes measured by the net income of Landlord from all sources, unless any such taxes are levied or assessed against Landlord as a substitute for, in whole or in part, any Imposition. 

“Land”: The parcel of land described on Exhibit B attached to this Lease. 

“Lease Year”: Each consecutive twelve (12) month period during the Term of this Lease, provided that the last Lease Year
shall end on the Expiration Date.

performed outside the Premises in order to comply with Requirements, and (iii) the cost of which does not exceed One Hundred Thousand Dollars ($100,000.00) in any one instance.

2. Tenant’s and Landlord’s Rights. Landlord hereby leases the Premises to Tenant pursuant to the terms of this Lease. Tenant
shall have access to the Premises and Common Areas on a 24-hour/7-days per week basis. The Premises includes the corridors and hallways, stairwells, elevators, restrooms
and other areas located within the Building. The common areas include the non-exclusive use of the external areas located on the Project (excluding any part of the Premises), that are designated by Landlord
from time to time as common areas for the Building or Project (the “Common Areas”); provided, however, that (i) the manner in which such public and Common Areas are maintained and operated shall be at the sole discretion of
Landlord, and (ii) Tenant’s use thereof shall be subject to (A) the provisions of any covenants, conditions and restrictions regarding the use thereof now or hereafter recorded against the Project, and (B) such reasonable, non-discriminatory rules, regulations and restrictions as Landlord may make from time to time that do not materially increase Tenant’s obligations under the Lease, materially decrease Tenant’s rights under
the Lease, or materially impair Tenant’s ability to utilize the Premises for the operation of Tenant’s business as currently conducted or intended to be conducted. Landlord reserves the right from time to time to use any of the Common
Areas, or roof, risers and conduits of the Building for telecommunications and/or any other purposes (so long as such does not materially increase Tenant’s obligations under the Lease, materially decrease Tenant’s rights under the Lease,
or materially impair Tenant’s ability to utilize the Premises for a first class cGMP antibody manufacturing facility), and to do any of the following: (1) make any changes, additions, improvements, repairs and/or replacements in or to the
Project or any portion or elements thereof, including, without limitation, (x) changes in the location, size, shape and number of driveways, entrances, loading and unloading areas, ingress, egress, direction of traffic, landscaped areas,
walkways, public and private streets, plazas, courtyards, transportation facilitation areas and common areas, and (y) expanding or decreasing the size of the Project and any Common Areas and other elements thereof, including adding, deleting
and/or excluding buildings thereon and therefrom; (2) close temporarily any of the Common Areas while engaged in making repairs, improvements or alterations to the Project; (3) retain and/or form a common area association or associations
under covenants, conditions and restrictions to own, manage, operate, maintain, repair and/or replace all or any portion of the landscaping, driveways, walkways, public and private streets, plazas, courtyards, transportation facilitation areas
and/or other Common Areas located outside of the Building and, subject to Section 5 below, include the Common Area assessments, fees and taxes charged by the association(s) and the cost of maintaining, managing,
administering and operating the association(s), in Operating Expenses or Tax Expenses; and (4) perform such other acts and 

  
 6 













 
make such other changes with respect to the Project as Landlord may, in the exercise of good faith business judgment, deem to be appropriate. In connection with the exercise of any rights set
forth in this Section 2 by Landlord, Landlord shall use commercially reasonable efforts to minimize any material adverse interference with Tenant’s business at the Premises, and any unreasonable interference with
Tenant’s access to the Premises, as a result thereof. Prior to knowingly causing any material interference with Tenant’s business at the Premises or Tenant’s access thereto, Landlord shall meet and confer with Tenant, and each shall
promptly and in good faith, develop a mutually agreed upon plan to ameliorate any such interference, Tenant’s agreement to such plan not to be unreasonably withheld. 

3. Term; Condition and Acceptance of Premises. 

3.1 Initial Term and Acceptance of Premises. 

3.1.1 Initial Term. Except as hereinafter provided, and unless sooner terminated or extended pursuant to the provisions of this Lease,
the Term of this Lease shall commence on the Commencement Date and end on the Expiration Date.

as provided in this Lease (including this Section 3.1.2) and except as described in Exhibit C attached hereto and incorporated herein by reference (the “Work Letter”), Tenant agrees to accept
the Premises in their “as-is” condition, without any representations or warranties by Landlord, and with no obligation of Landlord to make any alterations or improvements to the Premises or to
provide any tenant improvement allowance. Tenant also acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty with respect to the suitability of the Premises or the Building for the conduct of
Tenant’s business. Promptly following determination of the Commencement Date, Landlord and Tenant shall execute a Confirmation of Term in the form as set forth in Exhibit D attached to this Lease. Landlord represents and warrants that
Landlord is the fee owner of the Building and has the full right and authority to enter into this Lease without the necessary consent of any other person or entity that has not already been obtained; that the terms of this Lease do not violate any
easements, restrictions or other encumbrances recorded against the Building or Project, in any material manner which would materially impair Tenant’s ability to utilize the Premises for a first class cGMP antibody manufacturing facility; and
that Landlord has not received written notice of any action, suit or proceeding pending, or threatened against Landlord or affecting Landlord’s ownership of the Building or Project or enforceability of this Lease. 

3.1.3 Early Entry. Landlord shall permit Tenant to access and enter the Premises on the date that the Lease is mutually executed and
delivered (the “Early Entry Date”), solely for purposes of Tenant’s planning for and performing the build out and installation of the Improvements and installing Tenant’s furniture, fixtures and equipment in the Premises.
For the avoidance of doubt, Tenant’s access and use of the Premises pursuant to this Section 3.1.3 (and solely for the purposes permitted in this Section 3.1.3) shall not be deemed to be
Tenant’s commencement of operations within all or any part of the Premises. In no event may Tenant conduct its business or operations from the Premises until after the Commencement Date. Such limited purpose entry and use of the Premises by
Tenant shall be at Tenant’s sole risk and shall also be subject to all of the provisions of this Lease including, but not limited to, the requirement to obtain the insurance required pursuant to this Lease and to deliver insurance certificates
as required herein. Notwithstanding the immediately preceding sentence, Tenant shall not be required to pay Rent prior to the Commencement Date.

 3.2 Option to Extend. 

3.2.1 Exercise of Option to Extend Term. If (i) Tenant has not been in default of this Lease (beyond the expiration of applicable
notice and cure periods) more than two (2) times during the Lease Term and (ii) Tenant has not received a written notice of a monetary or other material default during the period beginning on the date that Tenant exercises its Extension
Option and continuing until the day which precedes the commencement of the Extended Term, Tenant shall have two (2) options (as to each, an “Extension Option”) to extend the Lease Term for an additional period of ten
(10) years each (as to each, an “Extended Term”). To exercise an Extension Option with respect to an Extended Term, Tenant shall give notice to Landlord not more than fifteen (15) months and not less than twelve
(12) months prior to the expiration of the initial Lease Term or the then expiring Extended Term, as applicable, (“Election Notice”). 

3.2.2 Fair Market Rent. If Tenant properly and timely exercises an Extension Option pursuant to Section 3.2.1
above, the Extended Term shall be upon all of the same terms, covenants and conditions of this Lease; provided, however, that the Base Rent applicable to the Premises for such Extended Term shall be one hundred percent (100%) of the “Fair
Market Rent” for space comparable to the Premises as of the commencement of such Extended Term. “Fair Market Rent” shall mean the annual rental being charged for lab/office space in buildings comparable to the Building and
located in Emeryville, California taking into account location, condition, and improvements of the comparable buildings as compared to the location, condition and lab/office improvements to the Premises as of the Commencement Date. If applicable,
the Annex shall be disregarded for purposes of calculating Fair Market Rent. 
 3.2.3 Determination of Rent. Within forty-five
(45) days after the date of the Election Notice (the “Outside Date”) Landlord and Tenant shall negotiate in good faith, in the manner set forth in this Section 3.2.3, in an attempt to determine Fair
Market Rent for an Extended Term. If Tenant timely and properly exercises an Extension Option, within fifteen (15) days of Landlord’s receipt of the Election Notice, Landlord shall notify Tenant of Landlord’s determination of Fair
Market Rent for the applicable Term. If Tenant in good faith objects in writing to Landlord’s determination of Fair Market Rent within thirty (30) days following the date upon which Landlord notifies Tenant of its determination, then
Landlord and Tenant shall attempt to agree upon the Fair Market Rent using their best good-faith efforts; provided that if Tenant fails to object to Landlord’s determination within such thirty (30) day period, then Tenant shall be deemed
to have accepted Landlord’s determination of Fair Market Rent. If Landlord and Tenant fail to reach agreement within thirty (30) days following Tenant’s objection, then each party shall make a separate determination of Fair Market
Rent, and such determinations shall be submitted to arbitration, in accordance with Section 3.2.4, below, no later than ten (10) days following the Outside Date. 

3.2.4 Appraisal. If it becomes necessary to determine the Fair Market Rent for the Premises by appraisal, the real estate
“appraiser(s)” indicated in this Section 3.2.4, each of whom shall be licensed real estate brokers (not licensed appraisers) with at least five (5) years experience leasing office space located in the
vicinity of the Premises, shall be appointed and shall act in accordance with the following procedures: 

  
 8 













 If the parties are unable to agree on the Fair Market Rent within the allowed time, either
party may demand an appraisal by giving written notice to the other party, which demand to be effective must state the name, address and qualifications of an appraiser selected by the party demanding the appraisal (“Notifying
Party”). Within ten (10) days following the Notifying Party’s appraisal demand, the other party (“Non-Notifying Party”) shall either approve the appraiser selected by the
Notifying Party or select a second properly qualified appraiser by giving written notice of the name, address and qualification of said appraiser to the Notifying Party. If the Non-Notifying Party fails to
select an appraiser within the ten (10) day period, the appraiser selected by the Notifying Party shall be deemed selected by both parties and no other appraiser shall be selected. If two (2) appraisers are selected, they shall select a
third appropriately qualified appraiser within ten (10) days of selection of the second appraiser. If the two (2) appraisers fail to select a third qualified appraiser, the third appraiser shall be appointed by the then presiding judge of
the county where the Premises are located upon application by either party. 
 If two (2) or more of the appraisers agree on the Fair
Market Rent for the Premises at the initial meeting, such agreement shall be determinative and binding upon the parties hereto and the agreeing appraisers shall forthwith notify both Landlord and Tenant of the amount set by such agreement. If
multiple appraisers are selected and two (2) appraisers are unable to agree on the Fair Market Rent for the Premises, each appraiser shall submit to Landlord and Tenant his or her respective independent appraisal of the Fair Market Rent for the
Premises, in simple letter form, within fifteen (15) days following appointment of the final appraiser. The parties shall then determine the Fair Market Rent for the Premises by averaging the appraisals; provided that any high or low appraisal,
differing from the middle appraisal by more than ten percent (10%) of the middle appraisal, shall be disregarded in calculating the average. 

If only one appraiser is selected, each party shall submit their determination of Fair Market Rent, and that appraiser shall notify the
parties in simple letter form of its determination as to whether the parties shall use Landlord’s or Tenant’s submitted determination of Fair Market Rent, and shall notify Landlord and Tenant thereof. If multiple appraisers are selected,
the appraisers shall meet not later than ten (10) business days following the selection of the last appraiser. If only one (1) appraiser is selected, then each party shall pay one-half (1/2) of the
fees and expenses of that appraiser. If three (3) appraisers are selected, each party shall bear the fees and expenses of the appraiser it selects and one-half (1/2) of the fees and expenses of the third
appraiser. 
 3.2.5 Restriction on Assignment. The Extension Option shall be personal to the originally named Tenant (and any
Permitted Transferee) and shall terminate upon any assignment of this Lease or any sublease of fifty percent (50%) or more of the Premises (other than in connection with a Permitted Transfer). 

3.2.6 Amendment to Lease. Immediately after the Fair Market Rent has been determined, the parties shall enter into an amendment to this
Lease setting forth the Base Rent for an Extended Term and the new expiration date of the Term of the Lease. All other terms and conditions of the Lease shall remain in full force and effect and shall apply during an Extended Term, except that:
(i) there shall be no further option to extend the Term except to the extent expressly provided in this Section 3.2, (ii) there shall be no rent concessions, and (iii) Landlord shall have no obligation to construct or install
improvements in the Premises, pursuant to Exhibit C or otherwise, and there shall be no construction allowance, tenant improvement allowance or similar provisions.

 3.3 Tenant’s Early Termination Option.

3.3.1 Tenant shall have a one-time option (the “Termination Option”) to terminate
this Lease, effective as of the last day of the one hundred twentieth (120th) full calendar month after the date Tenant first commenced payment of Base Rent (and without consideration to any
advance rent paid at lease execution) (the “Termination Date”). The Termination Option is granted subject to the following terms and conditions: 

(i) Tenant delivers to Landlord written notice of Tenant’s election to exercise the Termination Option, which notice
is given not later than twelve (12) full calendar months prior to the Termination Date; and 
 (ii) Tenant is not
then in default under this Lease beyond any applicable notice and cure periods either on the date that Tenant exercises the Termination Option, or unless waived in writing by Landlord, on the Termination Date; and 

(iii) Tenant pays to Landlord concurrently with Tenant’s exercise of the Termination Option and delivery of the
written notice as required above, a cash (or otherwise immediately available funds) lease termination fee (the “Fee”) equal to the aggregate of (a) any unamortized costs (including interest on such unamortized costs at the rate
of eight percent (8%) per annum) of the Tenant Improvement Allowance; and (b) six (6) full months of monthly Base Rent, which for purposes of calculating the Fee shall be the amount of the Base Rent payable by Tenant on the day preceding the
Termination Date. For purposes of exercising the Termination Option, Tenant may in good faith estimate the Fee required to be paid hereunder, and promptly after such exercise by Tenant, the parties shall true up the amount of the Fee if
Tenant’s estimate is not accurate within fifteen (15) days of delivery of written notice as provided in Section 3.3.1(i). 

3.3.2 If Tenant timely and properly exercises the Termination Option, (i) all Rent payable under the Lease shall be paid through and
apportioned as of the Termination Date (in addition to payment by Tenant of the Fee); (ii) neither party shall have any rights, estates, liabilities, or obligations under this Lease for the period accruing after the Termination Date, except those
which, by the provisions of this Lease, expressly survive the expiration or termination of the Term of the Lease; and (iii) Tenant shall surrender and vacate the Premises and deliver possession thereof to Landlord on or before the Termination
Date in the condition required under the Lease (as amended hereby) for surrender of the Premises. It is the parties’ intention that nothing contained herein shall impair, diminish or otherwise prevent Landlord or Tenant from recovering
from the other party such additional sums as may be necessary for payment of Tenant’s Percentage Share of Escalation Rent and any other sums due and payable under the Lease to the extent such expenses and sums have accrued prior to the
Termination Date, including without limitation, any sums required to repair any damage to the Premises and/or restore the Premises to the condition required under the provisions of the Lease. 

  
 10 













 3.3.3 The Termination Option shall automatically terminate and become null and void upon
the earlier to occur of (i) the breach or default by Tenant of any of the terms of this Lease beyond any applicable notice and cure periods at any time on or before the Termination Date on two (2) or more occasions; (ii) the
termination of Tenant’s right to possession of the Premises; or (iii) the failure of Tenant to timely or properly exercise the Termination Option as contemplated herein. This Termination Option may only be assigned as part of the
Lease, but subject to the provisions of Section 17 of the Lease. Time is of the essence with regard to each of the terms and provisions of this Section 3.3. 

4. Rent. 
 4.1
Obligation to Pay Base Rent. Except for the Abated Base Rent, Tenant shall pay Base Rent as set forth in the Basic Lease Information to Landlord, in advance, in equal monthly installments, commencing on or before the Commencement Date, and
thereafter on or before the first day of each calendar month during the Term. If the Commencement Date and/or Expiration Date is other than the first day of a calendar month, the installment of Base Rent for the first and/or last fractional month of
the Term shall be prorated on the basis of a thirty (30) day month. Tenant shall pay Landlord the first month’s Base Rent on or before the Commencement Date. 

4.2 Manner of Rent Payment. All Rent shall be paid by Tenant without notice, demand, abatement, deduction or offset, in lawful money of
the United States of America, payable to Landlord, at Landlord’s Rent Payment Address as set forth in the Basic Lease Information, or to such other person or at such other place as Landlord may from time to time designate by notice to Tenant.

 4.3 Additional Rent. All Rent not characterized as Base Rent or Escalation Rent shall constitute “Additional
Rent”, and if payable to Landlord shall, unless otherwise specified in this Lease, be due and payable fifteen (15) days after Tenant’s receipt of Landlord’s invoice therefor. 

4.4 Late Payment of Rent; Interest. Tenant acknowledges that late payment by Tenant of any Rent will cause Landlord to incur
administrative costs not contemplated by this Lease, the exact amount of which are extremely difficult and impracticable to ascertain based on the facts and circumstances pertaining as of the Lease Date. Accordingly, if any Rent is not paid by
Tenant within five (5) days of the date when due, then Tenant shall pay to Landlord, with such Rent, a late charge equal to five percent (5%) of such Rent; provided, however, Landlord shall waive the application of such late
charge once per 12-month period provided that Tenant pays the delinquent sum within five (5) days after the receipt of written notice that such amount is past due. Any Rent, other than late charges, due
Landlord under this Lease, if not paid within five (5) days of when due, shall also bear interest from the date due until paid, at the rate of the ten percent (10%) per annum; provided, however, that if such rate of interest shall
exceed the maximum rate allowed by law, the interest rate shall be automatically reduced to the maximum rate of interest permitted by applicable law.    The parties acknowledge that such late charge and interest represent a fair
and reasonable estimate of the administrative costs and loss of use of funds Landlord will incur by reason of a late Rent payment by Tenant, but Landlord’s acceptance of such late charge and/or interest shall not constitute a waiver of
Tenant’s default with respect to such Rent or prevent Landlord from exercising any other rights and remedies provided under this Lease, at law or in equity. 

  
 11 













 5. Calculation and Payments of Escalation Rent. In addition to paying the Base Rent
specified in this Lease, Tenant shall pay to Landlord, as additional rent, Tenant’s Percentage Share of Escalation Rent. All amounts due under this Section 5 as Escalation Rent shall be payable for the same periods and in the same manner,
time and place as the Base Rent. Without limitation on other obligations of Tenant which shall survive the expiration of the Lease Term, the obligations of Tenant to pay the Additional Rent provided for in this Section 5 shall survive the
expiration of the Lease Term. During each full or partial calendar year of the Term, Tenant shall pay Escalation Rent to Landlord in accordance with the following procedures: 

5.1 Payment of Estimated Escalation Rent. Prior to the Commencement Date and by December of each calendar year thereafter, or as soon
thereafter as practicable, Landlord shall give Tenant notice of its estimate of Escalation Rent due for the next ensuing calendar year. On or before the first day of each month from and after the Commencement Date, and during such next ensuing
calendar year, as the case may be, Tenant shall pay to Landlord in advance, in addition to Base Rent, one-twelfth (1/12th) of such estimated Escalation Rent. In the event such notice is given after December
31st of any year during the Term, (i) Tenant shall continue to pay Escalation Rent on the basis of the prior calendar year’s estimate until the month after such notice is given, (ii) subsequent payments by Tenant shall be based on the
estimate of Escalation Rent set forth in Landlord’s notice, and (iii) with the first monthly payment of Escalation Rent based on the estimate set forth in Landlord’s notice, Tenant shall also pay the difference, if any, between the
amount previously paid for such calendar year and the amount which Tenant would have paid through the month in which such notice is given, based on Landlord’s noticed estimate or, in the alternative, if such amount previously paid by Tenant for
such calendar year through the month in which such notice is given exceeds the amount which Tenant would have paid through such month based on Landlord’s noticed estimate, Landlord shall credit such excess amount against the next monthly
payments of Escalation Rent due from Tenant, except that if a credit amount is due Tenant after termination of this Lease, Landlord shall pay to Tenant any excess remaining after Landlord credits such amount against any sums owed by Tenant to
Landlord. If at any time Landlord reasonably determines that the Escalation Rent for the current calendar year will vary from Landlord’s estimate by more than five percent (5%), Landlord may, by notice to Tenant, revise its estimate for such
calendar year, and subsequent payments by Tenant for such calendar year shall be based upon such revised estimate. 
 5.2 Escalation Rent
Statement and Adjustment. Within one hundred fifty (150) days after the close of each calendar year, or as soon thereafter as practicable, Landlord shall deliver to Tenant a statement of the actual Escalation Rent for such calendar year
(the “Statement”), accompanied by a statement prepared by Landlord showing in reasonable detail the Operating Expenses and the Real Estate Taxes comprising the actual Escalation Rent. If the Statement shows that Tenant owes an
amount less than the payments previously made by Tenant for such calendar year, Landlord shall credit the difference first against any sums then owed by Tenant to Landlord and then against the next payment or payments of Rent due Landlord, except
that if a credit amount is due Tenant after termination of this Lease, Landlord shall pay to Tenant any excess remaining after Landlord credits such amount against any sums owed by Tenant to Landlord. If the Statement shows that Tenant owes an
amount more than the payments previously made by Tenant for such calendar year, Tenant shall pay the difference to Landlord within fifteen (15) days after delivery of the statement. 

  
 12 













 5.3 Proration for Partial Year. If the Commencement Date is other than the first day
of a calendar year or if this Lease terminates other than on the last day of a calendar year (other than due to Tenant’s default), the amount of Escalation Rent for such fractional calendar year shall be prorated on a daily basis. Upon such
termination, Landlord may, at its option, calculate the adjustment in Escalation Rent prior to the time specified in Section 5.2 above. Tenant’s obligation to pay Escalation Rent, as set forth in
Section 5.2, above, shall survive the expiration or termination of this Lease. 
 5.4 Audit. After delivery
to Landlord of at least thirty (30) days’ prior written notice delivered no later than one hundred twenty (120) days after receipt of a Statement, Tenant, at its sole cost and expense through any accountant designated by it, shall
have the right to examine and/or audit the books and records evidencing such costs and expenses for the previous one (1) calendar year, during Landlord’s reasonable business hours but not more frequently than once during any calendar year.
Any such accounting firm designated by Tenant may not be compensated on a contingency fee basis. The results of any such audit (and any negotiations between the parties related thereto) shall be maintained strictly confidential by Tenant and its
accounting firm and shall not be disclosed, published or otherwise disseminated to any other party other than to Landlord and its authorized agents. Landlord and Tenant each shall use its best efforts to cooperate in such negotiations and to
promptly resolve any discrepancies between Landlord and Tenant in the accounting of such costs and expenses. If Tenant fails to timely deliver written notice of Tenant’s desire to audit a Statement pursuant to this Section 5.4 or Tenant
fails to commence and complete such audit within six (6) months after Landlord’s delivery of the Statement in question, then Tenant shall be deemed to have approved of such Statement and such Statement shall be final and binding upon
Tenant. If through such audit it is determined that there is a discrepancy of more than five percent (5%) in the amount of Escalation Rent payments made by Tenant for such calendar year when compared to the actual Escalation Rent for such year, then
Landlord shall reimburse Tenant for the reasonable accounting costs and expenses incurred by Tenant in performing such audit, including Tenant’s outside auditors or accountants (but excluding Tenant’s
in-house personnel). 
 5.5 Adjustment of Tenant’s Percentage Interest in the Project. If
Landlord constructs any additional Other Buildings within the Project, then effective as of the commencement of such construction, Tenant’s Percentage Interest in the Project shall be recalculated as equal to the quotient of the Rentable Area
of the Building divided by the rentable area of the Project, including the rentable area of such additional Other Building, such rentable area to be determined in accordance with BOMA standards then used by Landlord in its determination of the
Rentable Area for all the Other Buildings. In the event Tenant’s Percentage Share is changed during a calendar year by reason of a change in the Rentable Area of the Premises or a change in the total Rentable Area of the Building, Tenant’s
Percentage Share shall thereafter mean the result obtained by dividing the then Rentable Area of the Premises (excluding the Equipment Area) by the then total Rentable Area of the Building, or Project, as applicable, and multiplying such quotient by
one hundred (100). For the purposes of determining Tenant’s Percentage Share of Escalation Rent, Tenant’s Percentage Share shall be determined on the basis of the number of days during such calendar year at each such Percentage Share.


  
 13 













 
Notwithstanding the foregoing, Landlord hereby agrees that, during the initial Lease Term, the rentable square footage of the Premises shall only be redetermined upon a physical change to the
size of the Premises (other than the addition of an Annex, as defined below) or as the result of a new load factor applicable to tenants of the Project due to new common area amenities. 

6. Impositions Payable by Tenant. Tenant shall pay all Impositions prior to delinquency. If billed directly to Tenant, Tenant shall pay
such Impositions and concurrently deliver to Landlord evidence of such payments. If any Impositions are billed to Landlord or included in bills to Landlord for Real Estate Taxes or other charges, then Tenant shall pay to Landlord all such amounts
within fifteen (15) days after delivery of Landlord’s invoice therefor. If applicable law prohibits Tenant from reimbursing Landlord for an Imposition, but Landlord may lawfully increase the Base Rent to account for Landlord’s payment
of such Imposition, the Base Rent payable to Landlord shall be increased to net to Landlord the same return without reimbursement of such Imposition as would have been received by Landlord with reimbursement of such Imposition. Tenant’s
obligation to pay Impositions which have accrued and remain unpaid upon the expiration or earlier termination of this Lease shall survive the expiration or earlier termination of this Lease. 

7. Use of Premises. 
 7.1
Permitted Use; CUP. The Premises shall be used solely for the Permitted Use and for no other use or purpose. 
 7.2 No Violation of
Requirements. Tenant shall not do or permit to be done, or bring or keep or permit to be brought or kept, in or about the Premises, or any other portion of the Building or the Project, anything which (i) is prohibited by, will in any way
conflict with, or would invalidate any Requirements; or (ii) would cause a cancellation of any insurance policy carried by Landlord or Tenant, or give rise to any defense by an insurer to any claim under any such policy of insurance, or
increase the existing rate of or adversely affect any insurance policy carried by Landlord, or (iii) subject Landlord to any liability or responsibility for injury to any person or property; or (iv) will in any way materially obstruct or
interfere with the rights of other tenants or occupants of the Project, or injure or unreasonably annoy them; provided, however, that the operations of tenant that are in compliance with all Requirements and are consistent with the ordinary course
business operations of other tenants of the Project, or are consistent with the ordinary course of business operations of first class cGMP antibody manufacturing facilities shall not be deemed to breach clauses (ii), (iii) or (iv) above. If
Tenant does or permits anything to be done (other than activities consistent with the ordinary course of business operations of first class cGMP antibody manufacturing facility) which increases the cost of any of Landlord’s insurance, or which
results in the need, in Landlord’s reasonable judgment, for additional insurance by Landlord or Tenant with respect to any portion of the Premises, the Building or the Project, then Tenant shall reimburse Landlord, upon demand, for any such
additional costs or the costs of such additional insurance, and/or procure such additional insurance at Tenant’s sole cost and expense. Exercise by Landlord of such right to require reimbursement of additional costs (including the costs of
procuring of additional insurance) shall not limit or preclude Landlord from prohibiting Tenant’s impermissible use of the Premises or from invoking any other right or remedy available to Landlord under this Lease. 

  
 14 













 7.3 Compliance with Legal, Insurance and Life Safety Requirements. Landlord
represents that, as of the date of this Lease, it has not received written notice that the Common Areas of the Project and/or Base Building are in violation of any Requirements. Tenant, at its cost and expense, shall promptly comply with all
Requirements applicable to Tenant’s use or occupancy of, or business conducted in, the Building, and shall maintain the Building and all portions thereof in compliance with all applicable Requirements. The judgment of any court of competent
jurisdiction, or the admission of Tenant or Landlord in any action or proceeding involving such party, whether or not the other party is party thereto, that such party is in non-compliance with any Requirement
shall be conclusive of that fact. In addition, subject to the provisions of Article 10 below, Tenant shall, at its sole cost and expense, make all modifications to any portion of the Project outside the Building (including whether structural
or capital in nature), which are necessitated, in whole or in part, by (i) Tenant’s use or occupancy of, or business conducted in, the Building, for purposes other than general ordinary office use, (ii) any Tenant Improvements or
Alterations, or (iii) any default by Tenant. Notwithstanding any provision herein to the contrary, modifications to any portion of the Project outside the Building, or to the Base Building, that are required by Requirements in connection with
Tenant’s obtaining any building permit for the Improvements, including, without limitation, modifications required to make the then-current path of travel to and from the Premises to comply with the ADA (collectively, “Base
Modifications”) shall be made at Landlord’s sole cost and expense, and not included as an Operating Expense; provided, however, the parties acknowledge that Landlord has provided that certain Warm Up Allowance for the
Warm Up Work (each as defined in Exhibit C), and accordingly, Landlord shall only have an obligation to fund Base Modifications to the extent that such Base Modification work (a) is not included in the Warm Up Allowance, (b) does
not arise in connection with Tenant’s construction of the Annex, and (c) is not triggered as a result any changes to the Warm Up Work attached to this Lease made by or at the request of Tenant (other than changes to the Warm Up Work
required by governmental authorities). 
 7.4 No Nuisance. Tenant shall not (i) do or permit anything to be done in or about the
Premises, or any other portion of the Project, which would injure or materially annoy, or obstruct or interfere with the rights of, Landlord or other occupants of the Project, or others lawfully in or about the Project; (ii) use or allow the
Premises to be used in any manner inappropriate for comparable buildings in Emeryville, California, or for any improper or objectionable purposes; or (iii) cause, maintain or permit any nuisance or waste in, on or about the Premises, or any
other portion of the Project; provided, however, that the operations of Tenant that are in compliance with all Requirements and are consistent with the ordinary course business operations of other tenants of the Project, or are
consistent with the ordinary course of business operations of first class cGMP antibody manufacturing facilities, shall not be deemed to breach this Section 7.4. 

7.5 Hazardous Materials. 

7.5.1 Compliance with Environmental Laws. Simultaneously herewith, Tenant has delivered to Landlord Tenant’s executed initial
Hazardous Materials Disclosure Certificate (the “Initial HazMat Certificate”), in the form attached hereto as Exhibit H, to be approved or disapproved by Landlord in its reasonable discretion. Tenant covenants, represents and
warrants to Landlord that the information in the Initial HazMat Certificate is true and correct and accurately describes the use(s) of Hazardous Materials which will be made and/or used on the 

  
 15 













 
Premises by Tenant. Tenant shall, commencing with the date which is one year from the Commencement Date and continuing every year thereafter, deliver to Landlord, an executed Hazardous Materials
Disclosure Certificate (the “HazMat Certificate”), in substantially the form attached hereto as Exhibit H, describing Tenant’s then present use of Hazardous Materials on the Premises, and any other reasonably necessary
documents as requested by Landlord; provided, however, Tenant shall deliver an updated HazMat Certificate at any time that Tenant desires Landlord to approve a change to any information in a HazMat Certificate previously approved by
Landlord. Tenant shall provide to Landlord access to all testing results that are required as a provision of any permits issued to Tenant in connection with Hazardous Materials. Except pursuant to a Landlord approved HazMat Certificate, Tenant shall
not be entitled to use or store any Hazardous Materials on, in, or about any portion of the Premises or Project without, in each instance, obtaining Landlord’s prior written consent thereto. If Landlord, in its commercially reasonable
discretion, expressly consents in writing to any such usage or storage, then Tenant shall be permitted to use and/or store only those Hazardous Materials and in such quantities (a) that are necessary for Tenant’s business, and (b), if
applicable, to the extent disclosed in the most recent HazMat Certificate. Tenant agrees that any changes to the type and/or quantities of Hazardous Materials specified in the most recent HazMat Certificate may be implemented only with the prior
written consent of Landlord, which consent may be given or withheld in Landlord’s reasonable discretion. Without limiting the generality of Section 7.3 above, Tenant and all other Tenant Parties shall at all times
comply with all applicable Environmental Laws with respect to the use and occupancy of any portion of the Project pursuant to this Lease. Tenant and all other Tenant Parties shall not generate, store, handle, or otherwise use, or allow, the
generation, storage, handling, or use of, Hazardous Materials in the Premises or transport the same through the Project, except (i) for nominal amounts of household cleaning materials and office supplies which are the minimum amount necessary
for the operation of Tenant’s business or as otherwise disclosed and approved by Landlord in a HazMat Certificate, and (ii) in accordance with the Rules and Regulations, all Environmental Laws and such other conditions as Landlord may from
time to time impose. In the event of a release of any Hazardous Materials caused by, or due to the act or neglect of, Tenant or any other Tenant Parties, Tenant shall immediately notify Landlord and take such remedial actions, at Tenant’s sole
cost and expense, as Landlord may direct in Landlord’s reasonable discretion as necessary or appropriate to abate, remediate and/or clean up the same. If so elected by Landlord by notice to Tenant, Landlord shall take such remedial actions on
behalf of Tenant at Tenant’s sole cost and expense. In any event, Landlord shall have the right, without liability or obligation to Tenant, to direct and/or supervise Tenant’s remedial actions and to specify the scope thereof and
specifications therefor. Tenant and the other Tenant Parties shall use, handle, store and transport any Hazardous Materials in accordance with applicable Environmental Laws, and shall notify Landlord of any notice of violation of Environmental Laws
which it receives from any governmental agency having jurisdiction. In no event shall Landlord be designated as the “generator” on, nor shall Landlord be responsible for preparing, any manifest relating to Hazardous Materials generated or
used by Tenant or any other Tenant Parties. 
 7.5.2 California Health & Safety Code
Section 25359.7. Additional information regarding environmental conditions at the Project is included in Exhibit E to this Lease, which is attached hereto and incorporated by reference herein.

 7.5.3 Exculpation of Tenant. Tenant shall not be liable to Landlord for nor
otherwise obligated to Landlord under any provision of the Lease with respect to the following: 
 (i) any claim, remediation, obligation,
investigation, obligation, liability, cause of action, attorneys’ fees, consultants’ cost, expense or damage resulting from any Hazardous Materials present in, on or about the Premises to the extent not caused or otherwise permitted,
directly or indirectly, by Tenant or the other Tenant Parties; or (ii) the removal, investigation, monitoring or remediation of any Hazardous Material present in, on or about the Premises caused by any source, including third parties, other
than Tenant or the other Tenant Parties; provided, however, Tenant shall be fully liable for and otherwise obligated to Landlord under the provisions of this Lease for all liabilities, costs, damages, penalties, claims, judgments, expenses
(including without limitation, attorneys’ and experts’ fees and costs) and losses to the extent (a) Tenant or any of the other Tenant Parties contributes to the presence of such Hazardous Materials, or Tenant and/or any of the other
Tenant Parties exacerbates the conditions caused by such Hazardous Materials, or (b) Tenant and/or the other Tenant Parties allows or permits persons over which Tenant or any of the other Tenant Parties has control, and/or for which Tenant or
any of the other Tenant Parties are legally responsible for, to cause such Hazardous Materials to be present in, on, under, through or about any portion of the Premises, or (c) Tenant and/or any of the other Tenant Parties does not take all
reasonably appropriate actions to prevent such persons over which Tenant or any of the other Tenant Parties has control and/or for which Tenant or any of the other Tenant Parties are legally responsible from causing the presence of Hazardous
Materials in, on, under, through or about any portion of the Premises. 
 7.6 Special Provisions Relating to The Americans With
Disabilities Act of 1990. 
 7.6.1 Allocation of Responsibility to Landlord. As between Landlord and Tenant, Landlord shall be
responsible to ensure that the Common Areas and path of travel to the Building shall comply with the requirements of Title III of the Americans with Disabilities Act of 1990 (42 U.S.C. 12181, et seq., The Provisions Governing Public Accommodations
and Services Operated by Private Entities), and all regulations promulgated thereunder, and all amendments, revisions or modifications thereto now or hereafter adopted or in effect in connection therewith (hereinafter collectively referred to as the
“ADA”), and to take such actions and make such alterations and improvements as are necessary for such compliance. All costs incurred by Landlord in discharging its responsibilities under this
Section 7.6.1 shall, if eligible as set forth in Section 1.1, be included in Operating Expenses. 
 7.6.2
Allocation of Responsibility to Tenant. As between Landlord and Tenant, subject to Section 7.3, Tenant, at its sole cost and expense, shall be responsible that the Building, all Tenant Improvements and Alterations to the Building,
Tenant’s use and occupancy of the Building, and Tenant’s performance of its obligations under this Lease, comply with the requirements of the ADA, and to take such actions and make such Alterations as are necessary for such compliance;
provided, however, that Tenant shall not make any such Alterations except in compliance with Section 10. 
 7.6.3 General.
Notwithstanding anything in this Lease to the contrary, no act or omission of Landlord, including any approval, consent or acceptance by Landlord or Landlord’s agents, employees or other representatives, shall be deemed an agreement,
acknowledgment, warranty, or other representation by Landlord that Tenant has complied with the ADA or that any action, alteration or improvement by Tenant complies or will comply with the 

  
 17 













 
ADA or constitutes a waiver by Landlord of Tenant’s obligations to comply with the ADA under this Lease or otherwise. Any failure of Landlord to comply with the obligations of the ADA shall
not relieve Tenant from any obligations under this Lease or constitute or be construed as a constructive or other eviction of Tenant or disturbance of Tenant’s use and possession of the Premises. California law requires Landlord to notify
Tenant whether Landlord has had the Premises inspected by a Certified Access Specialist (CASp). Landlord hereby discloses to Tenant that Landlord has not caused the Premises to be so inspected. A CASp can inspect the Premises and determine
whether the Premises comply with all of the applicable construction-related accessibility standards under state law. Although state law does not require a CASp inspection of the Premises, Landlord may not prohibit Tenant from obtaining a CASp
inspection of the Premises for the occupancy or potential occupancy of the Tenant, if requested by Tenant. The parties shall mutually agree on the arrangements for the time and manner of the CASp inspection, and the cost of making any repairs
necessary to correct violations of construction-related accessibility standards within the Premises. 
 8. Tenant Services. Tenant
shall be solely responsible, at its sole cost and expense, for the furnishing of all services and utilities to the Premises, including, but not limited to HVAC, electricity, water, telephone, telecommunications, janitorial, cleaning, pest control,
trash removal, security services, and replacement of all light bulbs, lamps, starters and ballasts for lighting fixtures within the Premises (as well as maintenance and repairs of the Premises in accordance with the provisions of Section 9
below). In connection with the foregoing, Tenant hereby agrees that (i) Landlord shall have absolutely no obligation to provide any such or other services or utilities to the Premises, it being agreed that this Lease is in the nature of a
“net” lease (although, as part of Operating Expenses, Landlord shall maintain and keep in service the existing utility connections located outside the Building connected to the exterior of the Building as necessary for distribution of such
utilities to the Premises by Tenant), (ii) Tenant shall contract directly with the applicable utility providers to provide all such utilities to the Premises, which utilities shall be separately metered, at Tenant’s cost, and (iii) Tenant
shall pay for the cost of such utilities supplied to the Premises (and for all services provided to the Premises) directly to the applicable provider thereof. All such services and utilities for the Premises shall be provided in such a manner so as
to maintain the Premises and Building in first-class condition consistent with the first-class nature of the Project, and if Tenant fails to do so, and such failure shall continue for five (5) days after notice from Landlord (which notice shall
not be required in the event of an emergency), Landlord shall have the right to provide such services and/or such utilities and any charges or costs incurred by Landlord in connection therewith shall be deemed Additional Rent due and payable by
Tenant upon receipt by Tenant of a written statement thereof from Landlord. 
 8.1 Overstandard Tenant Use. If Tenant shall use, or
desire to use, electricity, water, HVAC or any other utilities for the Premises in quantities that exceed the capacity of the equipment supplying the same to the Building as of the date Landlord delivers possession of the Premises to Tenant, then,
(i) subject to applicable laws, and the express provisions of this Lease, and subject to Landlord’s approval, which shall not be unreasonably withheld, conditioned or delayed, Tenant shall, at Tenant’s sole cost and expense, install
such supplemental equipment as may be reasonably required to provide such excess capacity, and (ii) Tenant shall pay for the costs of any increased wear and tear on existing Building systems and equipment (and repair and replacement of any such
Building systems and equipment in accordance with Section 9 below) caused by such excess use. 

  
 18 













 8.2 Interruption of Use. Tenant agrees that Landlord shall not be liable for damages,
by abatement of Rent or otherwise, for failure to furnish or delay in furnishing any service (including telephone and telecommunication services), or for any diminution in the quality or quantity thereof, when such failure or delay or diminution is
occasioned, in whole or in part, by breakage, repairs, replacements, or improvements, by any strike, lockout or other labor trouble, by inability to secure electricity, gas, water, or other fuel at the Building or Project after reasonable effort to
do so, by any riot or other dangerous condition, emergency, accident or casualty whatsoever, by act or default of Tenant or other parties, or by any other cause beyond Landlord’s reasonable control; and such failures or delays or diminution
shall never be deemed to constitute an eviction or disturbance of Tenant’s use and possession of the Premises or relieve Tenant from paying Rent or performing any of its obligations under this Lease. Furthermore, Landlord shall not be liable
under any circumstances for a loss of, or injury to, property or for injury to, or interference with, Tenant’s business, including, without limitation, loss of profits, however occurring, through or in connection with or incidental to a failure
to furnish any of the services or utilities as set forth in this Section 8. Notwithstanding anything to the contrary contained herein, Tenant shall be entitled to abate Base Rent due hereunder, to the extent that utility services to the
Premises are interrupted or suspended solely as a result of Landlord’s or its authorized representatives’ gross negligence or willful misconduct, for a period of three (3) or more consecutive business days, provided that, as a result
thereof, Tenant is prevented from using the Premises and/or there is a material disruption in Tenant’s ability to conduct cGMP manufacturing operations.    Landlord will use its best efforts to promptly restore utility or
service disruptions arising out of the gross negligence or willful misconduct of Landlord or its authorized representatives. 
 8.3
Janitorial Service. Landlord shall not be obligated to provide any janitorial services to the Premises or replace any light bulbs, lamps, starters and ballasts for lighting fixtures within the Premises. Tenant shall be solely responsible, at
Tenant’s sole cost and expense, for (i) performing all janitorial services, trash removal and other cleaning of the Premises, and (ii) replacement of all light bulbs, lamps, starters and ballasts for lighting fixtures within the
Premises, all as appropriate to maintain the Premises in a first-class manner consistent with the first-class nature of the Building and Project. Such services to be provided by Tenant shall be performed by contractors and pursuant to service
contracts approved by Landlord. Landlord shall have the right to inspect the Premises upon reasonable notice to Tenant and to require Tenant to provide additional cleaning, if necessary. In the event Tenant shall fail to provide any of the services
described in this Section 8.3 to be performed by Tenant within five (5) days after notice from Landlord, which notice shall not be required in the event of an emergency, Landlord shall have the right to provide such services and any charge
or cost incurred by Landlord in connection therewith shall be deemed Additional Rent due and payable by Tenant upon receipt by Tenant of a written statement of cost from Landlord. 

8.4 Separate Metering; Utility Consumption Data. All of the electricity, water and/or other utilities provided to the Premises are
separately metered, and Tenant shall pay for the cost of all such utilities so separately metered, or which are billed directly to Tenant, within ten (10) days after invoice. Tenant acknowledges and affirms its knowledge and understanding
of Landlord’s efforts to benchmark utility consumption within the entirety of the Building. As such, Tenant authorizes Landlord, acting on behalf of the Tenant, to request that the applicable utility provider deliver directly to Landlord the
necessary consumption information to enable Landlord to satisfy the requirements established by the US EPA for whole building data for the Energy Star 

  
 19 













 
Portfolio Manager tool. Tenant agrees to deliver such additional written authorization to Landlord as may be required or mandated by the applicable utility provider to enable delivery of the
requested consumption information. Tenant further authorizes Landlord to incorporate Tenant’s utility data in the Energy Star Portfolio Manager tool, and/or such other benchmarking initiatives as Landlord actively participates in, subject only
to the provision that Landlord will exercise commercially reasonable care to maintain the privacy of Tenant’s specific consumption data. Any public dissemination of such data shall be in aggregate with other Project tenants’ and
occupants’ consumption data, with no direct identification of individual Building or tenant usage. To the extent that the applicable utility provider is unable, or unwilling, to deliver the required utility consumption data as defined
hereinabove, Tenant acknowledges and recognizes its obligation to deliver to Landlord that information directly, as an integral requirement of this Lease. Such information shall be delivered in the format set forth by Landlord for this purpose, on
the same frequency as the invoicing received by Tenant from the utility provider for utilities consumed, unless some other frequency is agreed to in writing by Landlord and Tenant. 

9. Maintenance of Premises. Subject to Landlord’s repair obligations in Section 9.1 and Section 9.2 below, Tenant
shall, at Tenant’s own expense, and with contractors reasonably acceptable to Landlord and subject to Tenant’s compliance with the following provisions of this Section 9 and the provisions of Section 10 below, keep the Building
and every part thereof, including, without limitation, all tenant improvements, the roof (including roof membrane), elevators, fire and life safety systems, Alterations, additions, equipment, restrooms, fixtures and furnishings therein (including
all of the Building’s systems and equipment located within the Building and the HVAC equipment on the roof of the Building), all walls and wall coverings, doors, windows, glass, plate glass, ceilings and Generator Equipment (as defined below),
in first-class order, repair and condition at all times following the date Landlord delivers possession of the Premises to Tenant and throughout the Lease Term. Such repair obligations shall include, without limitation, replacement of items as may
be necessary to keep the same in the condition required hereinabove, notwithstanding that such replacements may be considered capital expenditures in accordance with accounting practices, and shall also include repairs of items above the ceiling,
repairs of items below the floors (but not the floor slabs), and/or repairs of items within walls, such as, but not limited to, all plumbing and pipes for restrooms, the equipment providing distribution within the Building of the HVAC from the HVAC
equipment on the roof, and the equipment providing distribution within the Building of all electricity and all other utilities required for the Premises (including all electrical panels in equipment rooms or elsewhere within the Building). As set
forth in Article 10, Landlord shall have approval rights with respect to repairs and/or replacements which would also be construed as a Major Alteration. Tenant’s repair obligations set forth hereinabove shall include, without limitation, the
obligation to promptly and adequately repair all damage to the Building and replace or repair all damaged or broken fixtures and appurtenances (subject, however, to the provisions below regarding casualty damage to the Building); provided however,
that, at Landlord’s option, or if Tenant fails to make any such repairs, after written notice and ten (10) days in which to commence the repair (which repairs Tenant shall thereafter diligently and continuously pursue to completion)
Landlord may, but need not, make such repairs and replacements, and Tenant shall pay Landlord the cost thereof upon being billed for same. Notwithstanding the foregoing terms of this Section 9, in the event that any
Building System serving the Premises and existing as of the date of substantial completion of the Warm Up Work requires replacement during the Term or any single capital repair expected to cost in excess of $25,000, then, at Tenant’s option,
either (a) 

  
 20 













 
Landlord shall be responsible for such replacement (or capital repair) and the cost thereof shall be amortized over the useful life of such item as reasonably determined by Landlord and Tenant
shall reimburse Landlord on a monthly basis during the remaining Term for the amortized cost thereof (together with interest on the unamortized balance at 8% per annum), or (b) Tenant shall be responsible for such replacement (or capital
repair) and Tenant shall pay the costs thereof and, once Tenant completes any such repair or replacement work and delivers to Landlord all invoices for such work mark as “paid” together with unconditional lien releases for all such work
that comply with the appropriate provisions, as reasonably determined by Landlord, of California Civil Code Sections 8132-8138, then Landlord shall reimburse Tenant for such work. With respect to any HVAC system serving the Premises and
existing as of the date of substantial completion of the Warm Up Work, the provisions of the immediately preceding sentence shall not apply if Tenant has failed to continuously maintain the HVAC service contracts required pursuant to
Section 9.3 below and/or Tenant has otherwise failed to perform (or caused to be performed) all required maintenance and service of the HVAC system. 

9.1 Landlord’s Reimbursable Repairs. Anything contained in Section 9 above to the contrary notwithstanding, and subject to
Sections 12 and 13 of this Lease, Landlord shall maintain as part of Operating Expenses exterior landscaping and the Common Areas. There shall be no abatement of Rent and no liability of Landlord by reason of any injury to or interference with
Tenant’s business arising from Landlord’s making of, or failure to make, any repairs, alterations or improvements in or to any portion of the Project, Building or the Premises or in or to fixtures, appurtenances and equipment therein.
Tenant hereby waives and releases its right to make repairs at Landlord’s expense under Sections 1941 and 1942 of the California Civil Code; or under any similar law, statute, or ordinance now or hereafter in effect. 

9.2 Landlord’s Other Repairs. Subject to the provisions of Sections 9 and 12, and except for repairs rendered necessary by any
Alterations or the intentional or negligent acts or omissions of Tenant or any of Tenant’s agents, employees, contractors, invitees and licensees (in which event(s), Tenant shall be responsible for the cost of any such repairs or replacements),
Landlord shall, at Landlord’s sole cost and expense (and not reimbursed as a component of Operating Expenses), keep in good repair the structural portions of the floors, foundations, building envelope (other than the roof), and exterior
perimeter walls of the Building. 
 9.3 HVAC, Fire/Life Safety, Elevator and Generator Maintenance and Repair by Tenant. Tenant shall,
at its own cost and expense, enter into a regularly scheduled preventive maintenance/service contract with a maintenance contractor for servicing all (i) hot water, heating, ventilating, and air conditioning (“HVAC”) systems
and equipment serving the Premises, (ii) all fire and life safety systems and elevators serving the Building, and (iii) all Generators in the Equipment Area. If Tenant desires to utilize maintenance contractors other than those authorized
by the manufacturer of such equipment, then the maintenance contractors and the service contracts must be reasonably approved by Landlord. The service contracts must include all services suggested by the equipment manufacturers, as applicable,
within the operation/maintenance manual and must become effective (and a copy thereof delivered to the Landlord) within thirty (30) days of the date of installation of such equipment. In the event Tenant fails to provide Landlord a copy of any
service contract which meets the requirements of this Section 9.3 within thirty (30) days of receipt by Tenant of Landlord’s written request for the same, Tenant shall pay to Landlord a late delivery fine of One Hundred and 00/100
Dollars ($100.00) for each month, or 

  
 21 













 
portion thereof, following such 30-day period in which Tenant fails to deliver the same. Upon Landlord’s request, Tenant shall furnish proof
reasonably satisfactory to Landlord at least once per year that all such systems and equipment are being serviced in accordance with the maintenance/service contracts. Landlord reserves the right to request such proof once per quarter. Subject to
Article 19 below, Landlord also reserves the right to inspect all HVAC, fire/life safety and elevator systems and Generator equipment with one (1) business day’s written notice. Within the three (3) month period preceding
Tenant’s vacating the Premises for any reason, whether due to expiration of earlier termination of the Term, or otherwise, Tenant shall have all such systems and equipment checked and serviced to insure proper functioning and shall furnish
Landlord satisfactory proof thereof upon request. 
 9.4 Generator Replacement. Notwithstanding the foregoing terms of this
Section 9, in the event that any Generator used by Tenant and existing as of the date of this Lease requires replacement during the Term, then Landlord shall be responsible for such replacement and the cost thereof shall be amortized over the
useful life of such item as reasonably determined by Landlord and Tenant shall reimburse Landlord on a monthly basis during the remaining Term for the amortized cost thereof (together with interest on the unamortized balance at 8% per annum). With
respect to any Generator serving the Premises and existing as of the date of substantial completion of the Warm Up Work, the provisions of the immediately preceding sentence shall not apply if Tenant has failed to continuously maintain the Generator
service contracts required pursuant to Section 9.3 above and/or Tenant has otherwise failed to perform (or caused to be performed) all required maintenance and service of the Generators serving the Premises. 

10. Alterations to Premises. 

All Alterations to office areas, common areas and/or restrooms within the Building shall be made in accordance with the Building-standard
procedures, specifications, and details (including the standard for construction and quality of materials in the Project) as then established by Landlord, all applicable Requirements, and the provisions of this Article 10. All
Alterations to other areas within the Building such as lab space shall be made in accordance with all applicable Requirements and the provisions of this Article 10. The construction of Alterations that increase square footage of the Premises
shall not result in an increase in Rent or change to Tenant’s Percentage Share. 
 10.1 Landlord Consent; Procedure. Subject to
Section 10.7 below, Tenant shall not make or permit to be made any Alterations without Landlord’s prior written consent, which as to any Major Alterations may be given or withheld in Landlord’s reasonable
discretion. Landlord and Tenant acknowledge that Tenant may desire to make significant Alterations to the Building to facilitate the Permitted Use of the Premises by Tenant, which may include, Tenant removing certain areas of the 2nd floor slab, use
of portions of the 2nd floor as interstitial mechanical space for the purposes of serving cGMP areas in the Building, and/or to modify the ground floor slab in order to provide clearance for certain pieces of manufacturing equipment. Landlord shall
not unreasonably withhold consent to any such significant Alterations. Subject to Landlord’s consent as provided herein, Tenant may also seek to build an annex (the “Annex”) onto the Building and/or modify or expand the
Equipment Area in order for the Building to function for Tenant’s intended use. Unless Landlord otherwise agrees in writing, any such Annex construction or Equipment Area modification or expansion shall only occur, if at all, in the areas shown
on Exhibit A-2 

  
 22 













 
attached hereto. For purposes of this Article 10, Landlord is only permitted to withhold its consent to construction of Alterations (including, without limitation, the Annex) to the extent
Landlord reasonably and in good faith believes such proposed Alteration: (a) would materially and adversely affect the structure of the Building; (b) would materially affect Landlord’s ability to
re-lease the Building for the Permitted Use upon the expiration or earlier termination of the Lease; (c) would materially increase Landlord’s operating costs of the Project; and/or (d) would
materially interfere with the rights of other tenants in the Project; provided, however, Landlord shall at all times have the right to (i) approve any element of such Alterations that may be seen from the outside of the Premises
(including, without limitation, the appearance, exterior materials and colors, size and shape), and (ii) require reasonable and specific modifications to the Annex in order to maintain flexibility with respect to other potential future uses of
the Building and Project; and provided, further, Landlord shall have the right to require Tenant to remove any such Alterations and restore the Premises upon surrender, subject to the terms of Section 10.6
below. 
 10.2 General Requirements. 

10.2.1 All Alterations shall be designed and performed by or on behalf of Tenant at Tenant’s cost and expense; provided, however, that if
any Alterations require work to be performed outside the Premises, Landlord may elect to perform such work at Tenant’s expense. 

10.2.2 All Alterations shall be performed only by licensed, insured and bonded contractors, engineers or architects reasonably approved by
Landlord, and shall be made in accordance with complete and detailed architectural, mechanical and engineering plans and specifications approved in writing by Landlord. Landlord shall not unreasonably withhold or delay its approval of any such
contractors, engineers, architects, plans or specifications; provided, however, that Landlord may specify contractors, engineers or architects to perform work affecting the structural portions of the Project or the Building systems. Tenant shall
engage only labor that is harmonious and compatible with other labor working in the Project. In the event of any labor disturbance caused by persons employed by Tenant or Tenant’s contractor, Tenant shall immediately take all actions necessary
to eliminate such disturbance. 
 10.2.3 Prior to commencement of the Alterations, Tenant shall deliver to Landlord (i) any building or
other permit required by Requirements in connection with the Alterations; (ii) a copy of executed construction contract(s); and (iii) written acknowledgments from all materialmen, contractors, artisans, mechanics, laborers and any other
persons furnishing to Tenant with respect to the Premises any labor, services, materials, supplies or equipment in excess of Five Thousand Dollars ($5,000.00) in the aggregate that they will look exclusively to Tenant for payment of any sums in
connection therewith and that Landlord shall have no liability for such costs. In addition, Tenant shall require its general contractor to carry and maintain the following insurance at no expense to Landlord, and Tenant shall furnish Landlord with
satisfactory evidence thereof prior to the commencement of construction of the Alterations: (A) commercial general liability insurance with limits of not less than $2,000,000 combined single limit for bodily injury and property damage,
including personal injury and death, and contractor’s protective liability, and products and completed operations coverage in an amount not less than $500,000 per incident, $1,000,000 in the aggregate; (B) comprehensive automobile
liability insurance with a policy limit of not less than $1,000,000 each accident for bodily injury and property damage, providing coverage at least as broad as the Insurance Services Office (ISO) Business Auto


  
 23 













 
Coverage form covering Automobile Liability, code 1 “any auto,” and insuring against all loss in connection with the ownership, maintenance and operation of automotive equipment that is
owned, hired or non-owned; (C) worker’s compensation with statutory limits and employer’s liability insurance with limits of not less than $100,000 per accident, $500,000 aggregate disease
coverage and $100,000 disease coverage per employee; and (D) “Builder’s All Risk” insurance in an amount, not to exceed a reasonable amount, approved by Landlord covering the Alterations, including such extended coverage endorsements
as may be reasonably required by Landlord. All such insurance policies (except workers’ compensation insurance) shall be endorsed to add Landlord, any Encumbrancer and Landlord’s designated agents as additional insureds with respect to
liability arising out of work performed by or for Tenant’s general contractor, to specify that such insurance is primary and that any insurance or self-insurance maintained by Landlord shall not contribute with it, and to provide that coverage
shall not be reduced, terminated, cancelled or materially modified except after thirty (30) days’ prior written notice has been given to Landlord. Landlord may inspect the original policies of such insurance coverage at any time. Upon
Landlord’s request, Tenant shall deliver complete certified copies of such policies. Tenant’s general contractor shall furnish Landlord evidence of insurance for its subcontractors as may be reasonably required by Landlord. 

10.2.4 Tenant shall give Landlord at least fifteen (15) days’ prior written notice of the date of commencement of any construction
on the Premises to afford Landlord the opportunity of posting and recording appropriate notices of non-responsibility. Tenant shall comply with the requirements of Section 3110.5 of the California Civil
Code as the contracting owner, to the extent applicable, and prior to commencement of construction, Tenant shall provide Landlord with evidence of compliance with said statute. Tenant acknowledges that the contractual waiver of the benefits of
California Civil Code Section 3110.5 is expressly declared to be against public policy. 
 10.2.5 Tenant shall promptly commence
construction of Alterations, cause such Alterations to be constructed in a good and workmanlike manner and in such a manner and at such times so that any such work shall not unreasonably or materially disrupt or interfere with the use, occupancy or
operations of other tenants or occupants of the Project, and complete the same with due diligence as soon as possible after commencement. All trash which may accumulate in connection with Tenant’s construction activities shall be removed by
Tenant at its own expense from the Premises and the Project. 
 10.3 Landlord’s Right to Inspect. Landlord or its agents shall
have the right (but not the obligation) to inspect the construction of Alterations, and to require corrections of faulty construction or any material deviation from the plans for such Alterations as approved by Landlord; provided, however, that no
such inspection shall (i) be deemed to create any liability on the part of Landlord, or (ii) constitute a representation by Landlord that the work so inspected conforms with such plans or complies with any applicable Requirements, or
(iii) give rise to a waiver of, or estoppel with respect to, Landlord’s continuing right at any time or from time to time to require the correction of any faulty work or any material deviation from such plans. In addition, under no
circumstances shall Landlord be liable to Tenant for any damage, loss, cost or expense incurred by Tenant on account of Tenant’s plans and specifications, Tenant’s contractors, mechanics or engineers, design or construction of any
Alteration, or delay in completion of any Alteration. 

  
 24 













 10.4 Tenant’s Obligations Upon Completion. Promptly following completion of any
Alterations, Tenant shall (i) furnish to Landlord “as-built” drawings and specifications in CAD format showing the Alterations as made and constructed in the Premises, (ii) cause a timely
notice of completion to be recorded in the Office of the Recorder of the County of Alameda in accordance with Civil Code Section 8182 or any successor statute, and (iii) deliver to Landlord evidence of full payment and unconditional final
waivers of all liens for labor, services, or materials in excess of Five Thousand Dollars ($5,000.00) in the aggregate. 
 10.5
Repairs. If any part of the Building Systems shall be damaged during the performance of Alterations, Tenant shall promptly notify Landlord, and Landlord may elect to repair such damage at Tenant’s sole expense. Alternatively, Landlord
may require Tenant to repair such damage at Tenant’s sole expense using contractors approved by Landlord. 
 10.6 Ownership and
Removal of Alterations. 
 10.6.1 Ownership. All Alterations shall become a part of the Project and immediately belong to
Landlord without compensation to Tenant, unless Landlord consents otherwise in writing; provided, however, that personal property, equipment, trade fixtures (including, without limitation, Tenant’s manufacturing and test equipment) and movable
furniture, each that may be removed without material damage to the Premises (collectively, the “FF&E”) shall remain the property of Tenant. Tenant shall have the right to remove any FF&E installed by Tenant during the Term
so long as Tenant promptly caps off and makes safe the Premises and repairs all damage to the Premises and Project caused by such removal. 

10.6.2 Removal. If required by Landlord by written notice to Tenant delivered at the time Landlord approves any Alteration, Tenant,
prior to the expiration of the Term or earlier termination of this Lease, shall, at Tenant’s sole cost and expense, (i) remove any or all such Alterations identified by Landlord for removal, (ii) restore the Premises to the condition
existing prior to the installation of such Alterations, and (iii) repair all damage to the Premises or Project caused by the removal of such Alterations. Tenant shall use a contractor reasonably approved by Landlord for such removal and repair.
If Tenant fails to remove, restore and repair under this Section, then Landlord may remove such Alterations and perform such restoration and repair, and Tenant shall reimburse Landlord for costs and expenses incurred by Landlord in performing such
removal, restoration and repair and in addition to all other remedies available to Landlord. If there are Alterations that are required to be removed by Tenant and have not been removed by Tenant by the expiration or earlier termination of the
Lease, Landlord may require Tenant to hold-over possession of the Premises pursuant to Article 25 below until such time as Tenant vacates and has surrendered possession of the Premises in the condition required by this Lease. Subject to the
foregoing provisions regarding removal, all Alterations shall be Landlord’s property and at the expiration of the Term or termination of this Lease shall remain, at Landlord’s sole election, on the Premises without compensation to Tenant.

 10.7 Minor Alterations. Notwithstanding any provision in the foregoing to the contrary, Tenant may construct Minor Alterations in
the Premises without Landlord’s prior written consent, but with prior notification to Landlord. Except to the extent inconsistent with this Section 10.7, Minor Alterations shall otherwise comply with the provisions of
this Article 10. All references in this Lease to “Alterations” shall mean and include Minor Alterations, unless specified to the contrary. 

  
 25 













 10.8 Landlord’s Expenses. In connection with installing or removing Alterations,
Tenant shall pay all reasonable and actual third party out-of-pocket fees and costs incurred by Landlord for review and approval of Tenant’s plans, specifications
and working drawings, and an administration fee for Landlord’s oversight of any such construction, installation or removal of Alterations (in an amount not to exceed 1.5% of the cost thereof). Tenant shall pay the amount of all fees and costs
owing pursuant to this Section 10.8 within thirty (30) days after receipt from Landlord of a statement or invoice therefor. 

11. Liens. Except in the ordinary course of equipment financing liens that do not attach to the Premises, Building or Project, Tenant
shall keep the Premises, the Building and the Project free from any liens arising out of any work performed or obligations incurred by or for, or materials furnished to, Tenant or any Tenant Parties pursuant to this Lease or otherwise. Landlord
shall have the right to post and keep posted on the Premises any notices required by law or which Landlord may deem to be proper for the protection of Landlord, the Premises, the Building and the Project from such liens and to take any other action
at the expense of Tenant that Landlord, in its commercially reasonable judgment, deems necessary or appropriate to prevent, remove or discharge such liens. In the event such lien is filed against the Premises, Building or Project, Tenant covenants
and agrees to cause it to be immediately released and removed of record or “bonded over” by providing a surety bond reasonably satisfactory to Landlord in an amount equal to at least one hundred fifty percent (150%) of the amount of the
contested lien claim or demand. If Tenant fails to post such bond or have such lien removed within ten (10) days of notice of such lien, Landlord, at its sole option, may immediately take all action necessary to release and remove such lien,
without any duty to investigate the validity thereof, and all sums, costs and expenses, including reasonable attorneys’ fees and costs, incurred by Landlord in connection with such lien shall be deemed additional Rent under this Lease and shall
be due and payable by Tenant upon demand. 
 12. Damage or Destruction. 

12.1 Obligation to Repair. Except as otherwise provided in this Article 12, if the Premises are damaged or destroyed by fire or
other casualty, Landlord shall, as soon as reasonably practicable (but in no event more than sixty (60) days after such event), notify Tenant in writing (“Landlord’s Damage Notice”) of the estimated time, in
Landlord’s reasonable judgment, required to repair such damage or destruction. If Landlord’s estimate of time is less than two hundred seventy (270) days after the date of damage or destruction, then (i) Landlord shall proceed
with all due diligence to repair the Premises (excluding Tenant’s personal property, trade fixtures and any Tenant Improvements or Alterations installed by or on behalf of Tenant other than the Warm Up Work), and/or the portion of the Building
or the Project necessary for Tenant’s use and occupancy of the Premises, to substantially the condition existing immediately before such damage or destruction, as permitted by and subject to then applicable Requirements; and (ii) this
Lease shall remain in full force and effect. In all cases, to the extent such damage or destruction did not result from the negligence or willful act or omission of Tenant or other Tenant Parties, Base Rent shall abate for such part of the Premises
rendered unusable by Tenant in the conduct of its business during the time such part is so unusable and not actually used by Tenant or any other Tenant Parties, in the proportion that the Rentable Area contained in the unusable part of the Premises
bears to the total Rentable Area of the Premises. 

  
 26 













 12.2 Landlord’s Election. If Landlord determines that the necessary repairs
cannot be completed within two hundred seventy (270) days after the date of damage or destruction, or if such damage or destruction arises from causes not covered by Landlord’s insurance policy then in force, Landlord may elect, in its
sole and exclusive discretion, in its notice to Tenant pursuant to Section 12.1, to (i) terminate this Lease or (ii) repair the Premises (excluding Tenant’s personal property, trade fixtures and any Tenant Improvements or
Alterations installed by or on behalf of Tenant other than the Warm Up Work) or the portion of the Building or the Project necessary for Tenant’s use and occupancy of the Premises pursuant to the applicable provisions of Section 12.1
above. If Landlord terminates this Lease, then this Lease shall terminate as of the date of occurrence of the damage or destruction. 
 12.3
Tenant’s Termination Option. If (i) Landlord does not elect to terminate this Lease pursuant to Landlord’s termination right as provided above, (ii) the damage is not the result of Tenant’s negligence or willful
misconduct, (iii) the damage substantially interferes with Tenant’s access to or usage of the Premises and Tenant does not thereafter use the Premises, and (iv) Landlord’s restoration work cannot, in the reasonable opinion of
Landlord’s licensed contractor, be substantially completed within two hundred seventy (270) days after the date of Landlord’s Damage Notice, then Tenant may elect to terminate this Lease by delivering written notice thereof to
Landlord within thirty (30) days after Tenant’s receipt of Landlord’s Damage Notice, which termination shall be effective as of the date which is ninety (90) days after the date such termination notice is delivered to Landlord.

 12.4 Tenant Repairs. If the Lease is not terminated in accordance with Section 12.2 or 12.3 above, Tenant shall promptly
repair all damage to all Tenant Improvements and all Alterations constructed by Tenant or on Tenant’s behalf, and shall pay the costs to repair all such Tenant Improvements constructed by Tenant or on Tenant’s behalf (including, without
limitation, those improvements constructed pursuant to Exhibit C attached hereto) and any Alterations other than the Warm Up Work. Tenant shall also promptly replace or repair, at Tenant’s cost and expense, all of Tenant’s movable
furniture, equipment, trade fixtures and other personal property in the Premises which Tenant shall be responsible for insuring during the Term of this Lease, as determined by Tenant. 

12.5 Damage at End of Term. Notwithstanding anything to the contrary contained in this Article 12, if the Premises, or any other
portion thereof or of the Building, are substantially damaged or destroyed by fire or other casualty within the last twelve (12) months of the Term (such that repairs and/or restoration work would take in excess of ninety (90) days) and
Tenant has not timely exercised any remaining Extension Option, then Landlord shall have the right, in its sole discretion, to terminate this Lease by notice to Tenant given within ninety (90) days after the date of such event. Such termination
shall be effective on the date specified in Landlord’s notice to Tenant, but in no event earlier than thirty (30) days after the date of Landlord’s notice. In addition, if the Premises is destroyed or materially damaged during the
last twelve (12) months of the Term such that restoration work cannot, in the reasonable opinion of Landlord’s licensed contractor, be substantially completed with ninety (90) days after the date of damage and such damage is not the
result of the negligence or willful misconduct of Tenant or Tenant’s agents, 

  
 27 













 
employees or contractors, and Tenant has not already, timely exercised any remaining Extension Option, then Tenant shall have the option to terminate this Lease by giving written notice to
Landlord of the exercise of such option within thirty (30) days after receipt of notice from Landlord as to the anticipated time necessary to substantially complete repairs thereto, in which event this Lease shall cease and terminate as of the
date of such notice. 
 12.6 Deductible and Uninsured Casualty. Tenant shall pay to Landlord, as additional Rent, the
commercially reasonable deductible amounts under the insurance policies obtained by Landlord and Tenant under this Lease if the proceeds are used to repair the Premises. However, if other portions of the Project are also damaged by said casualty and
insurance proceeds are payable therefor, then Tenant shall only pay its proportionate share of the commercially reasonable deductible equal to the Tenant’s Percentage Share for the Project. If any portion of the Premises is damaged and is not
fully covered by the aggregate of insurance proceeds received by Landlord and any applicable deductible, and Tenant does not voluntarily contribute any shortfall thereof, then Landlord shall have the right to terminate this Lease by delivering
written notice of termination to Tenant within sixty (60) days after the date of notice to Tenant of such event, whereupon this Lease shall terminate ten (10) business days after Tenant’s receipt of such notice, and Tenant shall
immediately vacate the Premises and surrender possession thereof to Landlord. 
 12.7 Waiver of Statutes. The respective rights and
obligations of Landlord and Tenant in the event of any damage to or destruction of the Premises, or any other portion of the Building or the Project, are governed exclusively by this Lease. Accordingly, Tenant hereby waives the provisions of any law
to the contrary, including California Civil Code Sections 1932(2), 1933(4), 1941 and 1942 and any similar or successor laws and any other laws providing for the termination of a lease upon destruction of the leased property. 

12.8 Meet and Confer. Notwithstanding any provision herein to the contrary, in the event Landlord elects to terminate the Lease pursuant
to the provisions of this Section 12, Landlord and Tenant shall first promptly meet and confer to discuss the economic losses that will be suffered by Landlord as a result of the damage or destruction giving rise to Landlord’s election to
terminate, and Landlord shall not unreasonably withhold its consent to withdraw Landlord’s election to terminate upon Tenant’s agreement (if Tenant so chooses) to financially offset such economic losses upon terms that are equitable and
reasonably approved by Landlord and Tenant; provided, however, Tenant shall not have the right to cause Landlord to withdraw Landlord’s election to terminate the Lease as provided herein. 

13. Eminent Domain. 
 13.1
Effect of Taking. Except as otherwise provided in this Article 13, if all or any part of the Premises is taken as a result of the exercise of the power of eminent domain or condemned for any public or quasi-public purpose, or if any
transfer is made in avoidance of such exercise of the power of eminent domain (collectively, “taken” or a “taking”), this Lease shall terminate as to the part of the Premises so taken as of the effective date of
such taking. On a taking of a portion of the Premises, Tenant shall have the right to terminate this Lease by notice to the Landlord within thirty (30) days after the effective date of such taking, if the portion of the Premises taken is of
such extent and nature so as to materially impair Tenant’s business use of the balance of the Premises, as reasonably determined by Tenant. Such termination shall be operative 

  
 28 













 
as of the effective date of the taking. Landlord may also terminate this Lease on a taking of any other portion of the Project if Landlord reasonably determines that such taking is of such extent
and nature as to render the operation of the remaining Project economically infeasible or to require a substantial reconstruction of such remaining portion. Landlord shall elect such termination by notice to Tenant given within thirty (30) days
after the effective date of such taking, and such termination shall be operative as of the effective date of such taking. Upon a taking of the Premises which does not result in a termination of this Lease, the Base Rent shall thereafter be reduced
as of the effective date of such taking in the proportion that the Rentable Area of the Premises so taken bears to the total Rentable Area of the Premises. 

13.2 Condemnation Proceeds. Except as hereinafter provided, in the event of any taking, Landlord shall have the right to all
compensation, damages, income, rent or awards made with respect thereto (collectively an “award”), including any award for the value of the leasehold estate created by this Lease. No award to Landlord shall be apportioned and,
except for Tenant’s rights hereinafter specified, Tenant hereby assigns to Landlord any right of Tenant in any award made for any taking. Tenant may seek to recover, at its cost and expense, as a separate claim, any damages or awards payable on
a taking of the Premises to compensate for the unamortized cost paid by Tenant for the alterations, additions or improvements, if any, made by Tenant during the initial improvement of the Premises pursuant to the Work Letter and for any Alterations,
or for Tenant’s personal property taken, or for interference with or interruption of Tenant’s business (including goodwill), or for Tenant’s removal and relocation expenses. 

13.3 Restoration of Premises. On a taking of the Premises which does not result in a termination of this Lease, Landlord and Tenant
shall restore the Premises as nearly as possible to the condition they were in prior to the taking in accordance with the applicable provisions and allocation of responsibility for repair and restoration of the Premises on damage or destruction
pursuant to Article 12 above, and both parties shall use any awards received by such party attributable to the Premises for such purpose. 

13.4 Taking at End of Term. Notwithstanding anything to the contrary contained in this Article 13, if the Premises, or any other
portion thereof or of the Building or the Project, are taken within the last twelve (12) months of the Term and Tenant has not timely exercised any remaining Extension Option, then Landlord or Tenant shall have the right, in its sole
discretion, to terminate this Lease by notice to the other party given within ninety (90) days after the date of such taking. Such termination shall be effective on the date specified in such notice to the other party, but in no event later
than the end of such ninety (90) day period. 
 13.5 Tenant Waiver. The rights and obligations of Landlord and Tenant on any
taking of the Premises or any other portion of the Building or the Project are governed exclusively by this Lease. Accordingly, Tenant hereby waives the provisions of any law to the contrary, including California Code of Civil Procedure Sections
1265.120 and 1265.130, or any similar or successor statute. 

  
 29 













 13.6 Meet and Confer. Notwithstanding any provision herein to the contrary, in the
event Landlord elects to terminate the Lease pursuant to the provisions of this Section 13, Landlord and Tenant shall first promptly meet and confer to discuss the economic losses that will be suffered by Landlord as a result of the taking
giving rise to Landlord’s election to terminate, and Landlord shall not unreasonably withhold its consent to withdraw Landlord’s election to terminate upon Tenant’s agreement (if Tenant so chooses) to financially offset such economic
losses upon terms that are equitable and reasonably approved by Landlord and Tenant; provided, however, Tenant shall not have the right to cause Landlord to withdraw Landlord’s election to terminate the Lease as provided herein.

 14. Insurance. 
 14.1
Liability Insurance. Tenant, at its cost and expense, shall procure and maintain, throughout the Term, the following insurance: 

14.1.1 Commercial General Liability Insurance. Commercial general liability insurance naming the Landlord as an additional insured
against any and all claims for bodily injury and property damage occurring in, or about the Premises arising out of Tenant’s use and occupancy of the Premises. Such insurance shall have a combined single limit of not less than One Million
Dollars ($1,000,000) per occurrence with a Two Million Dollar ($2,000,000) aggregate limit and excess umbrella liability insurance in the amount of Five Million Dollars ($5,000,000). Such general liability insurance shall be primary and non-contributing to any insurance available to Landlord and Landlord’s insurance shall be in excess thereto. In no event shall the limits of such insurance be considered as limiting the liability of Tenant
under this Lease. 
 14.1.2 Tenant’s Workers’ Compensation and Employer Liability Coverage. Tenant shall maintain
workers’ compensation insurance as required by law and employer’s liability insurance with limits of no less than One Million Dollars ($1,000,000.00) per occurrence. 

14.1.3 Tenant’s Property Insurance. Tenant shall maintain property insurance coverage, extended coverage and special extended
coverage insurance for all office furniture, trade fixtures, office equipment, merchandise, and all other items of Tenant’s property in, on, at, or about the Premises and the Project. Such policy shall (i) be written on the broadest
available “all risk” (special-causes-of-loss) policy form or an equivalent form acceptable to Landlord, (ii) include coverage for no less than the full
replacement cost (new without deduction for depreciation) of the covered items and property, and (iii) include vandalism and malicious mischief coverage, sprinkler leakage coverage, and earthquake sprinkler leakage coverage. 

14.1.4 Business Interruption, Loss of Income, and Extra Expense Coverage. Tenant shall maintain business interruption, loss of income,
and extra expense insurance covering all direct or indirect loss of income and charges and costs incurred arising out of all perils, failures, or interruptions, including any failure or interruption of Tenant’s business equipment (including,
without limitation, telecommunications equipment), and the prevention of, or denial of use of or access to, all or part of the Premises or the Project, as a result of those perils, failures, or interruptions. The business interruption, loss of
income, and extra expense coverage shall provide coverage for no less than twelve (12) months and shall be carried in amounts necessary to avoid any coinsurance penalty that could apply. 

  
 30 













 14.1.5 Other Tenant Insurance Coverage. Not more often than once every year and upon
not less than thirty (30) days’ prior written notice, Landlord may require Tenant, at Tenant’s sole cost and expense, to procure and maintain other types of insurance coverage and/or increase the insurance limits set forth above if
Landlord reasonably determines using commercially reasonable judgment such other insurance and/or increase is required to protect adequately the parties named as insureds or additional insureds under such insurance; provided such additional
insurance is consistent with the amounts and types of insurance then being required by reasonably prudent landlords of comparable buildings in the vicinity of the Building or as otherwise required by Landlord’s lenders. 

14.1.6 No Obligation to Insure for Certain Landlord Acts. Notwithstanding anything herein to the contrary, no policy of insurance that
Tenant is obligated to maintain hereunder is required to provide coverage for the gross negligence or willful misconduct of Landlord. 
 14.2
Form of Policies. All insurance required by this Article 14 shall be issued on an occurrence basis by solvent companies qualified to do business in the State of California. Any insurance required under this Article 14 may be
maintained under a “blanket policy”, insuring other parties and other locations, so long as the amount and coverage required to be provided hereunder is not thereby diminished. Notwithstanding the foregoing, Landlord shall have the right
to self-insure against any of the risks required to be insured against under this Article 14. Tenant shall provide Landlord a copy of each policy of insurance or a certificate thereof certifying that the policies contain the provisions
required hereunder. Tenant shall deliver such policies or certificates to Landlord within (30) days after the Lease Date, but in no event less than ten (10) business days prior to the Commencement Date or such earlier date as Tenant or
other Tenant Parties first enter the Premises and, upon renewal, not less than ten (10) days after the expiration of such coverage. All evidence of insurance required under this Lease and provided to Landlord shall provide (i) with respect
to Tenant’s liability insurance other than workers’ compensation insurance and employer’s liability insurance, that Landlord, Landlord’s managing agent and any other person requested by Landlord who has an insurable interest, is
designated as an additional insured without limitation as to coverage afforded under such policy and with respect to Tenant’s property insurance, that Landlord and any other person requested by Landlord who has an insurable interest, is
designated as a loss payee; (ii) for severability of interests or that the acts or omissions of one of the insureds or additional insureds shall not reduce or affect coverage available to any other insured or additional insured; (iii) that
the insurer agrees to endeavor to notify all additional insured of any cancellation of the policy within ten (10) days of the effective date of such cancellation (and in all events, Tenant shall notify Landlord ten (10) days prior to any
cancellation or non-renewal); and (iv) other than Tenant’s workers’ compensation insurance, employer’s liability insurance and business interruption insurance, that Tenant’s insurance
is primary and noncontributing with any insurance carried by Landlord. 
 14.3 Vendors’ Insurance. In addition to any other
provision in this Lease (including, without limitation, Article 10 above), Landlord may require Tenant’s vendors and contractors to carry such insurance as Landlord shall deem reasonably necessary. 

15. Waiver of Subrogation Rights. Notwithstanding anything to the contrary contained in this Lease, Landlord and Tenant, for themselves
and their respective insurers, agree to and do hereby release each other of and from any and all claims, demands, actions and causes of action that each may have or claim to have against the other for injuries sustained by employees or loss or
damage to property, both real and personal, notwithstanding that any such injuries sustained by 

  
 31 













 
employees or loss or damage may be due to or result from the negligence of either of the parties hereto or their respective employees or agents to the extent such loss is covered by any insurance
policy maintained or required to be maintained by either party under this Lease. Each party shall, to the extent such insurance endorsement is lawfully available at commercially reasonable rates, obtain or cause to be obtained, for the benefit of
the other party, a waiver of any right of subrogation which the insurer of such party may acquire against the other party by virtue of the payment of any such loss covered by such insurance. 

16. Tenant’s Waiver of Liability and Indemnification. 

16.1 Waiver and Release. Except to the extent due to the gross negligence or willful misconduct of Landlord, Landlord shall not be
liable to Tenant or other Tenant Parties (through third party beneficiary claims made by such Tenant Parties), and Tenant waives and releases Landlord and Landlord’s managing agent from, all claims for loss or damage to any property or injury,
illness or death of any person in, upon or about the Premises and/or any other portion of the Building (including claims caused in whole or in part by the act, omission, or neglect of other tenants, contractors, licensees, invitees or other
occupants of the Building or their agents or employees). The waiver and release contained in this Section 16.1 extends to the officers, directors, shareholders, members, partners, employees, agents and representatives of
Landlord. 
 16.2 Indemnification of Landlord. Tenant shall indemnify, defend, protect and hold Landlord harmless of and from any and
all losses, liens, liabilities, claims, demands, judgments, causes of action, damages, injuries, penalties, costs and expenses arising out of or in connection with (i) the making of any alterations, additions or other improvements made by or on
behalf of Tenant during the initial improvement of the Premises pursuant to the Work Letter or any Alterations, or (ii) injury to or death of persons or damage to property occurring or resulting directly or indirectly from: (A) the use or
occupancy of, or the conduct of business in, the Premises by Tenant, any other of the Tenant Parties, or Tenant’s subtenants or any of their respective officers, directors, employees, agents, contractors, invitees or licensees; (B) any
other occurrence or condition in or on the Premises; and (C) acts, neglect or omissions of Tenant or other Tenant Parties, in or about any portion of the Project, (iii) Tenant’s failure in any respect to comply with its obligations
set forth in Section 7.6.2, except to the extent such failure is the direct result of Landlord’s refusal to consent to Alterations required to achieve such compliance (provided, however, Landlord’s refusal to consent to a component of
Alterations that are not required to achieve compliance with Tenant’s obligations in Section 7.6.2 shall not alleviate Tenant of its indemnity obligation set forth in this Section 16.2(iii)), (iv) the use, operation and/or maintenance
of the Generator Equipment or any portion thereof, except with respect to Landlord’s obligations as set forth in Section 9.4, (v) Tenant’s failure to comply with Section 11, (vi) Tenant’s failure to timely vacate the
Premises and surrender to Landlord exclusive possession thereof upon the expiration or earlier termination of the Lease, and/or (vii) the removal of vehicles from the Parking Facility by Tenant or any Tenant Party. Tenant’s indemnity
obligation includes reasonable attorneys’ fees and costs, investigation costs and all other reasonable costs and expenses incurred by Landlord. If Landlord reasonably disapproves the legal counsel proposed by Tenant for the defense of any claim
indemnified against hereunder, Landlord shall have the right to appoint its own legal counsel, the reasonable fees, costs and expenses of which shall be included as part of Tenant’s indemnity obligation hereunder. The indemnification contained
in this Section 16.2 shall extend to the officers, 

  
 32 













 
directors, shareholders, partners, employees, agents and representatives (but not contractors) of Landlord and shall survive the expiration or earlier termination of this Lease. Notwithstanding
the provisions of this Section 16.2 above to the contrary, Tenant’s indemnity of Landlord shall not apply to: (a) any claims to the extent resulting from the gross negligence or willful misconduct of Landlord and
not insured or required to be insured by Tenant (based on the types and amounts of insurance required of Tenant pursuant to Section 14) under this Lease (collectively, the “Excluded Claims”); or
(b) any loss of or damage to Landlord’s property to the extent Landlord has waived such loss or damage pursuant to Section 15. In addition, Landlord shall indemnify, defend, protect and hold Tenant harmless from
all such Excluded Claims, except for (1) any loss or damage to Tenant’s property to the extent Tenant has waived such loss or damage pursuant to Section 15, and (2) any lost profits, loss of business or other
consequential damages. 
 17. Assignment and Subletting. 

17.1 Compliance Required. Tenant shall not, directly or indirectly, voluntary or by operation of law, sell, assign or otherwise transfer
this Lease, or any interest herein (collectively, “assign” or “assignment”), or sublet the Premises, or any part thereof, or permit the occupancy of the Premises by any person other than Tenant (collectively,
“sublease” or “subletting”, the assignee or sublessee under an assignment or sublease being referred to as a “transferee”), without Landlord’s prior consent given or withheld in
accordance with the express standards and conditions of this Article 17 and compliance with the other provisions of this Article 17. Any assignment or subletting made in violation of this Article 17 shall be void. As used
herein, an “assignment” includes any sale or other transfer (such as by consolidation, merger or reorganization) of a majority of the voting stock of Tenant, if Tenant is a corporation, or any sale or other transfer of a majority of
the beneficial interest in Tenant, if Tenant is any other form of entity. Tenant acknowledges that the limitations on assignment and subletting contained in this Article 17 are expressly authorized by California Civil Code
Section 1995.010 et seq., and are fully enforceable. 
 17.2 Request by Tenant; Landlord Response. If Tenant
desires to effect an assignment or sublease, Tenant shall submit to Landlord a request for consent together with the identity of the parties to the transaction, the nature of the transferee’s proposed business use for the Premises, the proposed
documentation for and terms of the transaction, and all other information reasonably requested by Landlord concerning the proposed transaction and the parties involved therein, including certified financial information, credit reports, the business
background and references regarding the transferee, and an opportunity to meet and meeting the transferee. Within twenty (20) days after the later of such meeting or the receipt of all such information required by Landlord, or within thirty
(30) days after the date of Tenant’s request to Landlord if Landlord does not request additional information or an meeting, Landlord shall have the right, by notice to Tenant, to: (i) consent to the assignment or sublease, subject to
the terms of this Article 17; or (ii) decline to consent to the assignment or sublease. 

  
 33 













 17.3 Conditions for Landlord Approval. Landlord shall not unreasonably withhold its
consent to a proposed subletting or assignment by Tenant. Without limiting the grounds on which it may be reasonable for Landlord to withhold its consent to an assignment or sublease, Tenant agrees that Landlord would be acting reasonably in
withholding its consent in the following instances: (i) if Tenant is then in default under this Lease beyond any applicable notice and cure period; (ii) if the transferee is a governmental or quasi-governmental agency, foreign or domestic;
(iii) if the transferee is an existing tenant in the Project; (iv) if, in Landlord’s sole judgment, the transferee’s business, use and/or occupancy of the Premises would (A) violate any of the terms of this Lease or the
lease of any other tenant in the Project, or (B) not be comparable to and compatible with the types of use by other tenants in the Project, (C) fall within any category of use for which Landlord would not then lease space in the Project
under its leasing guidelines and policies then in effect, or (D) results in an material increase in density per floor than typical of a Project of this nature or requires a material increase in services by Landlord; (v) if the financial
condition of the transferee does not meet the requirements applied by Landlord for other tenants in the Project under leases with comparable terms, or in Landlord’s sole judgment the business reputation of the transferee is not consistent with
that of other tenants of the Project; or (vi) in the case of a sublease, the rent payable by the subtenant is over fifteen percent (15%) less than the then prevailing rate being charged by Landlord for the lease of comparable space in the
Project. If Landlord consents to an assignment or sublease, the terms of such assignment or sublease transaction shall not be modified without Landlord’s prior written consent pursuant to this Article 17. Landlord’s consent to an
assignment or subletting shall not be deemed consent to any subsequent assignment or subletting. Notwithstanding the provisions of this Section 17.3, Tenant may sublease a portion of the Premises to an existing tenant at the Project so long as
Landlord does not then have comparable vacant space in a reasonably comparable size available to lease to such existing tenant. 
 17.4
Costs and Expenses. As a condition to the effectiveness of any assignment or subletting under this Article 17, Tenant shall pay to Landlord a processing fee of five hundred dollars ($500.00) plus all reasonable out-of-pocket costs and expenses, including attorneys’ fees and disbursements, incurred by Landlord in evaluating Tenant’s requests for assignment or sublease,
whether or not Landlord consents to an assignment or sublease. Tenant shall pay the processing fee with Tenant’s request for Landlord’s consent under Section 17.2. 

17.5 Payment of Excess Rent and Other Consideration. Tenant shall also pay to Landlord, promptly upon Tenant’s receipt thereof,
fifty percent (50%) of any and all rent, sums or other consideration, howsoever denominated, realized by Tenant in connection with any assignment or sublease transaction in excess of the Base Rent and Escalation Rent payable hereunder (prorated to
reflect the Rent allocable to the portion of the Premises if a sublease), after first deducting, (i) in the case of an assignment, reasonable real estate commissions and attorneys’ fees and expenses paid by Tenant in connection with such
assignment, any free rent, moving expenses or other monetary concessions offered to the assignee, and the reasonable hard and soft cost of any or all Alterations made to the Premises at Tenant’s cost when building out the initial Tenant
Improvements in the Premises and to otherwise effect the assignment, (ii) in the case of a sublease, reasonable real estate commissions and attorneys’ fees and expenses paid by Tenant in connection with such sublease, any free rent, moving
expenses or other monetary concessions offered to the sublessee, and the reasonable hard and soft cost of any or all Alterations made to the Premises at Tenant’s cost when building out the initial Tenant Improvements in the Premises and to
otherwise effect the sublease. 

  
 34 













 17.6 Assumption of Obligations; Further Restrictions on Subletting. Each assignee
shall, concurrently with any assignment, assume all obligations of Tenant under this Lease. Each sublease shall be in a form reasonably approved by Landlord and shall be made subject to this Lease and all of the terms, covenants and conditions
contained herein; and the surrender of this Lease by Tenant, or a mutual cancellation thereof, or the termination of this Lease in accordance with its terms, shall not work a merger and shall, at the option of Landlord, terminate all or any existing
subleases or operate as an assignment to Landlord of any or all such subleases. No sublessee (other than Landlord) shall have the further right to sublet. Any assignment by a sublessee of its sublease shall be subject to Landlord’s prior
consent in the same manner as a sublease by Tenant. No sublease, once consented to by Landlord, shall be modified without Landlord’s prior consent. No assignment or sublease shall be binding on Landlord unless the transferee delivers to
Landlord a fully executed counterpart of the assignment or sublease which contains the assumption by the assignee, or recognition by the sublessee, of the provisions of this Section 17.6, in form and substance satisfactory
to Landlord, but the failure or refusal of a transferee to deliver such instrument shall not release or discharge such transferee from the provisions and obligations of this Section 17.6, but such failure shall constitute a
default by Tenant under this Lease. 
 17.7 No Release. No assignment or sublease shall release Tenant from its obligations under this
Lease, whether arising before or after the assignment or sublease. The acceptance of Rent by Landlord from any other person shall not be deemed a waiver by Landlord of any provision of this Article 17. On a default by any assignee of Tenant
in the performance of any of the terms, covenants or conditions of this Lease, Landlord may proceed directly against Tenant without the necessity of commencing or exhausting remedies against such assignee. No consent by Landlord to any further
assignments or sublettings of this Lease, or any modification, amendment or termination of this Lease, or extension, waiver or modification of payment or any other obligations under this Lease, or any other action by Landlord with respect to any
assignee or sublessee, or the insolvency, or bankruptcy or default of any such assignee or sublessee, shall affect the continuing liability of Tenant for its obligations under this Lease and Tenant waives any defense arising out of or based thereon,
including any suretyship defense of exoneration. Landlord shall have no obligation to notify Tenant or obtain Tenant’s consent with respect to any of the foregoing matters. 

17.8 No Encumbrance. Notwithstanding anything to the contrary contained in this Article 17, Tenant shall have no right to
encumber, pledge, hypothecate or otherwise transfer this Lease, or any of Tenant’s interest or rights hereunder, as security for any obligation or liability of Tenant. 

17.9 Permitted Transfers. Notwithstanding anything to the contrary contained in this Section 17, so long as Tenant delivers to
Landlord (i) at least fifteen (15) business days prior written notice of its intention to assign or sublease the Premises to any Permitted Transferee, which notice shall set forth the name of the Permitted Transferee, (ii) a copy of
the proposed agreement pursuant to which such assignment or sublease shall be effectuated, and (iii) such other information concerning the Permitted Transferee as Landlord may reasonably require, including without limitation, information
regarding any change in the proposed use of any portion of the Premises and any financial information with respect to such Permitted Transferee, and so long as (a) any change in the proposed use of the subject portion of the Premises is in
conformance with the uses permitted to be made under this Lease and do not involve the use or storage of any Hazardous Materials except otherwise reasonably approved by Landlord in writing, and (b) if the Permitted


  
 35 













 
Transferee is not a Related Entity, the Permitted Transferee has a tangible net worth and net income, in the aggregate, computed in accordance with standard commercial real estate accounting
practices (but excluding goodwill as an asset), which is equal to or greater than Tenant as of the date of this Lease, then Tenant may assign this Lease or sublease any portion of the Premises (1) to any Related Entity, or (2) in
connection with any merger, consolidation or sale of substantially all of the assets of Tenant, or Tenant’s affiliates, without having to obtain the prior written consent of Landlord thereto (each such transfer shall be referred to herein as a
“Permitted Transfer” and each transferee pursuant to a Permitted Transfer shall be referred to herein as a “Permitted Transferee”). Any Permitted Transfer shall in no way relieve Tenant of any liability Tenant may
have under this Lease and such assignee or sublessee shall be jointly and severally liable with Tenant hereunder. For purposes of this Section 17, the term “Related Entity” shall mean any entity controlled by, under control
with, or in control of Tenant. The term “control” as used in the immediately preceding sentence shall mean having direct ownership of fifty percent (50%) or more of the ownership interests of an entity and having the ability to direct the
management and policies of such entity. 
 18. Rules and Regulations. Tenant shall observe and comply, and shall cause the other
Tenant Parties to observe and comply, with the Rules and Regulations of the Building, copies of which are attached to this Lease as Exhibit F, and, after notice thereof, with all modifications and additions thereto from time to time
promulgated in writing by Landlord which do not materially increase Tenant’s obligations under the Lease, materially decrease Tenant’s rights under the Lease, or materially impair Tenant’s ability to utilize the Premises as a first
class cGMP antibody manufacturing facility. Landlord shall not be responsible to Tenant or other Tenant Parties for noncompliance with any Rules and Regulations of the Building by any other tenant, sublessee, employee, agent, contractor, licensee,
invitee or other occupant of the Building. 
 19. Entry of Premises by Landlord. 

19.1 Right to Enter. Upon not less than one (1) business day’s notice to Tenant (except in emergencies or in order to provide
regularly scheduled or other routine Building standard services or additional services requested by Tenant, or post notices of nonresponsibility or other notices permitted or required by law when no such notice shall be required) Landlord and its
authorized agents, employees, and contractors may enter the Premises at reasonable hours to (and accompanied by Tenant if not in an emergency situation): (i) inspect the same; (ii) determine Tenant’s compliance with its obligations
hereunder; (iii) exhibit the same to prospective purchasers, lenders or tenants (with respect to prospective tenants, only during the last 12 months of the Term); (iv) supply any services to be provided by Landlord hereunder; (v) post
notices of nonresponsibility or other notices permitted or required by law; (vi) make repairs, improvements or alterations, or perform maintenance in or to, the Premises or any other portion of the Building, including Building systems; and
(vii) perform such other functions as Landlord deems reasonably necessary or desirable. Landlord may also grant access to the Premises to government or utility representatives and bring and use on or about the Premises such equipment as
reasonably necessary to accomplish the purposes of Landlord’s entry. Landlord shall use reasonable good faith efforts to effect all entries and perform all work hereunder in such manner as to minimize, to the extent practical, interference with
Tenant’s use and occupancy of the Premises. Notwithstanding any provision herein to the contrary, in all cases where Landlord requires or is granted access to the Premises, while within the Premises and except in the event of an emergency,
Landlord and its authorized agents, employees, and contractors, shall at all times comply with Tenant’s security policies and all standard operating procedures for the Premises.

 19.2 Tenant Waiver of Claims. Tenant acknowledges that Landlord, in connection with
Landlord’s activities under this Article 19, may, among other things, erect scaffolding or other necessary structures in the Premises and/or the Project, limit or eliminate access to portions of the Project (other than the
Premises), including portions of the common areas, or perform work in the Premises and/or the Project, which work may create noise, dust, vibration, odors or leave debris in the Premises and/or the Project, Landlord shall use commercially reasonable
efforts to abate any such dust and debris. Without limiting the generality of Section 16.1 above, Tenant waives any claim for damages for any inconvenience to or interference with Tenant’s business, or any loss of
occupancy or quiet enjoyment of the Premises, or any other loss, occasioned by any entry effected or work performed under this Article 19, and Tenant shall not be entitled to any abatement of Rent by reason of the exercise of any such right
of entry or performance of such work. No entry to the Premises by Landlord or anyone acting under Landlord shall constitute a forcible or unlawful entry into, or a detainer of, the Premises or an eviction, actual or constructive, of Tenant from the
Premises, or any portion thereof; provided, however, Landlord shall use commercially reasonable efforts to minimize any unreasonable interference with Tenant’s use and occupancy of the Premises as a result of any entry by Landlord permitted
under this Article 19. Prior to knowingly causing any interference with Tenant’s business or access at the Premises, Landlord shall meet and confer with Tenant to develop a reasonably agreeable plan to ameliorate any such interference,
which may include, reasonably scheduling Landlord’s activities during any Tenant planned shutdown of operations at the Premises. 
 20.

 20.1 Events of Default. The occurrence of any of the following events shall constitute a default by
Tenant under this Lease: 
 a. Nonpayment of Rent; Letter of Credit. Failure to pay any Rent when due, or failure to deposit a
replacement Letter of Credit or renew an expiring Letter of Credit or provide a substitute Letter of Credit or otherwise comply with the obligations regarding the Letter of Credit as described below within the time periods specified therein.

comprised of more than one person or entity, or any guarantor of Tenant’s obligations, or any of them, under this Lease. 
 f. Failure
to deliver the documents required to be delivered by Tenant under Articles 21, 23 and/or 31 within the applicable time period set forth in such Articles. 

20.2 Notice to Tenant. Upon the occurrence of any default, Landlord shall give Tenant notice thereof. Such notice shall replace rather
than supplement any equivalent or similar statutory notice, including any notices required by California Code of Civil Procedure Section 1161 or any similar or successor statute; and giving of such notice in the manner required by Article
28 shall replace and satisfy any service-of-notice procedures set forth in any statute, including those required by California Code of Civil Procedure
Section 1162 or any similar or successor statute. If a time period is specified below for cure of such default, then Tenant may cure such default within such time period, and if timely cured, such
non-performance shall not constitute a “default”. To the fullest extent allowed by law, Tenant hereby waives any right under law now or hereinafter enacted to any other time period for cure of
default. 
 a. Nonpayment of Rent. For failure to pay Rent within five (5) days after notice of such default from Landlord to
Tenant; provided, however, that following the second such notice in any calendar year, no additional notice shall be required and a default shall automatically have occurred upon any failure by Tenant to pay any when due; or 

b. Other Obligations. For failure to perform any obligation, covenant, condition or agreement under this Lease (other than nonpayment
of Rent, an assignment or subletting in violation of Article 17 or Tenant’s abandonment of the Premises or any other failure specified in Sections 20.1(b), (c) and (e) above) within thirty (30) days after Landlord’s
notice or, if the failure is of a nature requiring more than thirty (30) days to cure, then an additional sixty (60) days after the expiration of such thirty (30) day period, but only if Tenant commences said cure within such thirty
(30) day period and thereafter diligently pursues such cure to completion within such additional sixty (60) day period. 

  
 38 













 c. SNDA, Estoppels, LOCs, and Financials. For failure to deliver the documents
required to be delivered by Tenant under Articles 21, 23 and/or 31, or failure to deposit a replacement Letter of Credit or renew an expiring Letter of Credit or provide a substitute Letter of Credit or otherwise comply with the
obligations regarding the Letter of Credit as described below, within the applicable time period set forth in the Lease and within five (5) business days after delivery of Landlord’s further notice to Tenant of such default. 

d. No Cure Period. No cure period shall apply for any other event of default specified in Section 20.1(b), (c) or
(e). 
 20.3 Remedies Upon Occurrence of Default. On the occurrence of a default which Tenant fails to cure after notice and
expiration of the time period for cure, if any, specified in Section 20.2 above, Landlord shall have the right either (i) to terminate this Lease and recover possession of the Premises, or (ii) to continue this
Lease in effect and enforce all Landlord’s rights and remedies under California Civil Code Section 1951.4 (by which Landlord may recover Rent as it becomes due, subject to Tenant’s right to assign pursuant to Article 17).
Landlord may store any property of Tenant located in the Premises at Tenant’s expense or otherwise dispose of such property in the manner provided by law. In addition to the foregoing, if, at any time, Tenant is in default of any term,
condition or provision of this Lease and Landlord terminates the Lease during the initial Term based on such default, any express or implicit waiver by Landlord of Tenant’s requirement to pay Abated Base Rent shall be null and void and Tenant
shall immediately pay to Landlord all Abated Base Rent so expressly or implicitly waived by Landlord in accordance with the Basic Lease Information. If Landlord does not terminate this Lease, Tenant shall in addition to continuing to pay all Rent
when due, also pay Landlord’s costs of attempting to relet the Premises, any repairs and alterations necessary to prepare the Premises for such reletting, and brokerage commissions and attorneys’ fees incurred in connection therewith, less
the rents, if any, actually received from such reletting. Notwithstanding Landlord’s election to continue this Lease in effect, Landlord may at any time thereafter terminate this Lease pursuant to this Section 20.3.

 20.4 Damages Upon Termination. If and when Landlord terminates this Lease pursuant to Section 20.3,
Landlord may exercise all its rights and remedies available under California Civil Code Section 1951.2, including the right to recover from Tenant the worth at the time of award of the amount by which the unpaid Rent for the balance of the Term
after the time of award exceeds the amount of such Rent loss that the Tenant proves could have been reasonably avoided. As used herein and in Civil Code Section 1951.2, “time of award” means either the date upon which Tenant
pays to Landlord the amount recoverable by Landlord, or the date of entry of any determination, order or judgment of any court or other legally constituted body determining the amount recoverable, whichever occurs first. 

20.5 Computation of Certain Rent for Purposes of Default. For purposes of computing unpaid Rent pursuant to
Section 20.4 above, Escalation Rent for the balance of the Term shall be determined by averaging the amount paid by Tenant as Escalation Rent for the calendar year prior to the year in which the default occurred, increasing
such average amount for each calendar year (or portion thereof) remaining in the balance of the Term at a per annum compounded rate equal to the mean average rate of increase for the preceding five (5) calendar years in the United States
Department of Labor, Bureau of Labor Statistics, Consumer Price Index (All Urban Consumers, All Items, 1982-1984 = 100) for the Metropolitan Area of which San 

  
 39 













 
Francisco, California, is a part, and adding together the resulting amounts. If such Index is discontinued or revised, such computation shall be made by reference to the index designated as the
successor or substitute index by the United States Department of Labor, Bureau of Labor Statistics, or its successor agency, and if none is designated, by a comparable index as determined by Landlord in its sole discretion, which would likely
achieve a comparable result to that achieved by the use of the Consumer Price Index. If the base year of the Consumer Price Index is changed, then the conversion factor specified by the Bureau, or successor agency, shall be utilized to determine the
Consumer Price Index. 
 20.6 Landlord’s Right to Cure Defaults. If Tenant fails to pay Rent (other than Base Rent and Escalation
Rent) required to be paid by it hereunder, or fails to perform any other obligation under this Lease, and Tenant fails to cure such default within the applicable cure period, if any, specified in Section 20.2 above, then
Landlord may, without waiving any of Landlord’s rights in connection therewith or releasing Tenant from any of its obligations or such default, make any such payment or perform such other obligation on behalf of Tenant. All payments so made by
Landlord, and all costs and expenses incurred by Landlord to perform such obligations, shall be due and payable by Tenant as Rent immediately upon receipt of Landlord’s demand therefor. 

20.7 Waiver of Forfeiture. Tenant hereby waives California Code of Civil Procedure Section 1179, California Civil Code
Section 3275, and all such similar and/or successor laws now or hereinafter enacted which would entitle Tenant to seek relief against forfeiture in connection with any termination of this Lease. 

20.8 Remedies Cumulative. The rights and remedies of Landlord under this Lease are cumulative and in addition to, and not in lieu of,
any other rights and remedies available to Landlord at law or in equity. Landlord’s pursuit of any such right or remedy shall not constitute a waiver or election of remedies with respect to any other right or remedy. 

21. Subordination, Attornment and Nondisturbance. 

21.1 Subordination. This Lease is subject and subordinate to all present and future ground or underlying leases of the Project and to
the lien of any mortgages or trust deeds, now or hereafter in force against the Project, if any, and to all renewals, extensions, modifications, consolidations and replacements thereof, and to all advances made or hereafter to be made upon the
security of such mortgages or trust deeds, unless the holders of such mortgages or trust deeds, or the lessors under such ground lease or underlying leases, require in writing that this Lease be superior thereto. Tenant covenants and agrees in the
event any proceedings are brought for the foreclosure of any such mortgage, or if any ground or underlying lease is terminated, to attorn, without any deductions or set-offs whatsoever, to the purchaser upon
any such foreclosure sale, or to the lessor of such ground or underlying lease, as the case may be, if so requested to do so by such purchaser or lessor and to recognize such purchaser or lessor as the lessor under this Lease. Tenant shall, within
five (5) days of request by Landlord, execute such further commercially reasonable instruments or assurances as Landlord may reasonably deem necessary to evidence or confirm the subordination or superiority of this Lease to any such mortgages,
trust deeds, ground leases or underlying leases and the non-disturbance of Tenant’s leasehold estate. Tenant waives the provisions of any current or future statute, rule or law which may give or purport
to give Tenant any right or election to terminate or otherwise adversely affect this Lease and the obligations of the Tenant hereunder in the event of any foreclosure proceeding or sale. 

 

  
 40 













 21.2 Existing Agreement. Tenant hereby acknowledges that as of the date on which
Landlord and Tenant execute this Lease there is a deed of trust encumbering, and in force against, the Project in favor of the lender(s) set forth on Exhibit E attached hereto (the “Current Lender”). Simultaneously with
Tenant’s execution of this Lease, Tenant shall sign, notarize and deliver a subordination, non-disturbance and attornment agreement in the form of Exhibit G attached hereto
(“SNDA”) and Landlord shall promptly counter-sign the same and shall use commercially reasonable efforts to cause the Current Lender to counter-sign the same within sixty (60) days of the mutual execution of this Lease. If
Landlord at any time during the Lease Term causes the Project to be encumbered by a new deed of trust or mortgage pursuant to which the beneficiary of such deed of trust or mortgage is a party or entity other than the Current Lender, and/or if any
party which acquires, or otherwise succeeds to, Landlord’s interest in the Project (including, without limitation, any ground lessee) encumbers or places a lien against the Project with a mortgage, deed of trust or similar security instrument
and the beneficiary thereof requires this Lease to be subordinated to such encumbrance or lien, Landlord or the successor of Landlord will use commercially reasonable efforts to provide to Tenant a commercially reasonable subordination, non-disturbance and attornment agreement in form reasonably acceptable to Landlord or such successor of Landlord, the subject beneficiary and Tenant. If said SNDA is required and agreed upon by the aforesaid
parties, Landlord or the successor of Landlord, the subject beneficiary and Tenant shall cause any such subordination, non-disturbance and attornment agreement to be executed, acknowledged and recorded
concurrently with, or as soon as practicable after, the execution and recordation of any such lien, deed of trust or mortgage. In addition to the foregoing, if Landlord enters into a ground lease with regard to the Project and such ground lessee
requires this Lease to be subordinated to such ground lease, the ground lessee and ground lessor will use commercially reasonable efforts to provide to Tenant a subordination, non-disturbance and attornment
agreement in a commercially reasonable form reasonably acceptable to such ground lessee, ground lessor, any beneficiary of ground lessee, and to Tenant. Notwithstanding the foregoing, Landlord shall not be in default under this Lease and shall have
no liability to Tenant whatsoever if Landlord is unable to obtain and deliver to Tenant a subordination, non-disturbance and attornment agreement executed by the Current Lender or any subsequent lender,
beneficiary under deed of trust or ground lessor. Should Tenant have any requested changes to the SNDA attached to the initial draft of this Lease, Tenant covenants and agrees to pay all fees, costs and expenses incurred by Landlord in connection
with the negotiation or issuance of the SNDA. 
 22. Sale or Transfer by Landlord; Lease
Non-Recourse. 
 22.1 Release of Landlord on Transfer. Landlord may at any time transfer,
in whole or in part, its right, title and interest under this Lease and in the Building and the Project, or any portion thereof. If the original Landlord hereunder, or any successor to such original Landlord, transfers (by sale, assignment or
otherwise) its right, title or interest in the Building, all liabilities and obligations of the original Landlord or such successor under this Lease accruing from and after such transfer shall terminate, the original Landlord or such successor shall
automatically be released from such liabilities and obligations, and thereupon all such liabilities and obligations shall be binding upon the new owner. Tenant shall attorn to each such new owner. 

  
 41 













 22.2 Lease Nonrecourse to Landlord. Landlord shall in no event be personally liable
under this Lease, and Tenant shall look solely to Landlord’s interest in the Project, for recovery of any damages for breach of this Lease by Landlord or on any judgment in connection therewith. None of the persons or entities comprising or
representing Landlord (whether partners, members, shareholders, officers, directors, trustees, employees, beneficiaries, agents or otherwise) shall ever be personally liable under this Lease or liable for any such damages or judgment and Tenant
shall have no right to effect any levy of execution against any assets of such persons or entities on account of any such liability or judgment. Any lien obtained by Tenant to enforce any such judgment, and any levy of execution thereon, shall be
subject and subordinate to all encumbrances as specified in Article 21 above. 
 23. Estoppel Certificate. 

23.1 Procedure and Content. From time to time, and within ten (10) days after written notice by Landlord, Tenant shall execute,
acknowledge, and deliver to Landlord a commercially reasonable certificate certifying: (i) that this Lease is unmodified and in full force and effect (or, if there have been modifications, that this Lease is in full force and effect, as
modified, and identifying each modification); (ii) the Commencement Date and Expiration Date; (iii) that Tenant has accepted the Premises (or the reasons Tenant has not accepted the Premises), and if Landlord has agreed to make any alterations
or improvements to the Premises, that Landlord has properly completed such alterations or improvements (or the reasons why Landlord has not done so); (iv) the amount of the Base Rent and current Escalation Rent, if any, and the date to which such
Rent has been paid; (v) that to Tenant’s actual knowledge, Tenant has not committed any event of default, except as to any events of default specified in the certificate, and whether there are, to Tenant’s actual knowledge, any
existing defenses against the enforcement of Tenant’s obligations under this Lease; (vi) that to Tenant’s actual knowledge, no default of Landlord is claimed by Tenant, except as to any defaults specified in the certificate; and
(vii) such other factual matters as may be reasonably requested by Landlord. 
 23.2 Effect of Certificate. Any such certificate
may be relied upon by any prospective purchaser or encumbrancer of any part or interest in the Building or the Project or any encumbrancer (as defined in Section 21.1) and, at Landlord’s request, Tenant shall deliver
such certificate to Landlord and/or to any such entity and shall agree to such notice and cure provisions and such other matters as such entity may reasonably require. In addition, at Landlord’s request, Tenant shall provide to Landlord for
delivery to any such entity such information, including financial information that may reasonably be requested by any such entity. Any such certificate shall constitute a waiver by Tenant of any claims Tenant may have in contravention to the
information contained in such certificate and Tenant shall be estopped from asserting any such claim. If Tenant fails or refuses to give a certificate hereunder within the time period herein specified, then the information contained in such
certificate as submitted by Landlord shall conclusively be deemed correct for all purposes and binding upon Tenant, but such failure or refusal shall be an immediate default by Tenant without the necessity of delivering any further notice to Tenant.


  
 42 













 24. No Light, Air, or View Easement. Nothing contained in this Lease shall be deemed,
either expressly or by implication, to create any easement for light and air or access to any view. Any diminution or shutting off of light, air or view to or from the Premises by any structure which 

now exists or which may hereafter be erected, whether by Landlord or any other person, shall in no way affect this Lease or Tenant’s obligations
hereunder, entitle Tenant to any reduction of Rent, or impose any liability on Landlord. Further, under no circumstances at any time during the Term shall any temporary darkening of any windows of the Premises or any temporary obstruction of the
light or view therefrom by reason of any repairs, improvements, maintenance or cleaning in or about the Project in any way impose any liability upon Landlord or in any way reduce or diminish Tenant’s obligations under this Lease. 

25. Holding Over. No holding over by Tenant shall operate to extend the Term. If Tenant remains in possession of the Premises after
expiration or termination of this Lease, unless otherwise agreed by Landlord in writing, then (i) Tenant shall become a tenant at sufferance upon all the applicable terms and conditions of this Lease, except that Base Rent shall be increased to
equal 150% of the Base Rent then in effect; and (ii) such holding over by Tenant shall constitute an immediate default by Tenant. 
 26.
Security Deposit. Upon execution of this Lease, Tenant shall pay to Landlord the amount of the security deposit set forth in the Basic Lease Information as the “Security Deposit” under this Lease. The Security Deposit
shall be held by Landlord as security for the performance by Tenant of all its obligations under this Lease. If Tenant fails to pay any Rent due hereunder, or otherwise commits a default with respect to any provision of this Lease, Landlord may use,
apply or retain all or any portion of the Security Deposit for the payment of any such Rent or for the payment of any other amounts expended or incurred by Landlord by reason of Tenant’s default, or to compensate Landlord for any loss or damage
which Landlord may incur thereby. Tenant waives (a) California Civil Code Section 1950.7 and any and all other laws, rules and regulations applicable to security deposits in the commercial context (“Security Deposit
Laws”), and (b) any and all rights, duties and obligations either party may now or, in the future, will have relating to or arising from the Security Deposit Laws. Notwithstanding anything to the contrary herein, the Security Deposit
may be retained and applied by Landlord (1) to offset rent or additional rent which is unpaid either before or after termination of this Lease; (2) against other damages suffered by Landlord before or after termination of this Lease or to
otherwise restore the Premises to a clean and safe condition, reasonable wear and tear excepted; and (3) those sums reasonably necessary to compensate Landlord for any other loss or damage, foreseeable or unforeseeable, caused by the act or
omission of Tenant or any officer, employee, agent or invitee of Tenant, whether arising before or after. Exercise by Landlord of its rights hereunder shall not constitute a waiver of, or relieve Tenant from any liability for, any default. If all or
any portion of the Security Deposit is used or applied by Landlord for such purposes, Tenant shall within ten (10) days after written demand therefor deposit cash with Landlord in an amount sufficient to restore the Security Deposit to its full
amount. If Tenant performs all of Tenant’s obligations hereunder, the Security Deposit, or so much thereof as has not been used or applied by Landlord as permitted herein, shall be returned, without interest, to Tenant (or, at Landlord’s
option, to the last assignee, if any, of Tenant’s interest under this Lease) within thirty (30) days after the later of (i) the date of expiration or earlier termination of this Lease, or (ii) vacation of the Premises by Tenant
if the Premises has been left in the condition specified by this Lease. Upon termination of the original Landlord’s (or any successor owner’s) interest in the Premises, the original Landlord (or such successor) shall be released from
further liability with respect to the Security Deposit upon the original Landlord’s (or such successor’s) delivery of Security Deposit to the successor landlord and compliance with California Civil Code Section 1950.7(d), or successor
statute. 

  
 43 













 27. Waiver. Failure of Landlord to declare a default by Tenant upon occurrence
thereof, or delay in taking any action in connection therewith, shall not waive such default, but Landlord shall have the right to declare such default at any time after its occurrence. To be effective, a waiver of any provision of this Lease, or
any default, shall be in writing and signed by the waiving party. Any waiver hereunder shall not be deemed a waiver of subsequent performance of any such provision or subsequent defaults. The subsequent acceptance of Rent hereunder, or endorsement
of any check by Landlord, shall not be deemed to constitute an accord and satisfaction or a waiver of any preceding default by Tenant, except as to the particular Rent so accepted, regardless of Landlord’s knowledge of the preceding default at
the time of acceptance of the Rent. No course of conduct between Landlord and Tenant, and no acceptance of the keys to or possession of the Premises by Landlord before the Expiration Date shall constitute a waiver of any provision of this Lease or
of any default, or operate as a surrender of this Lease. 
 28. Notices and Consents; Tenant’s Agent for Service. All notices
required under this Lease and other information concerning this Lease (“Communications”) shall be personally delivered or sent by first class mail, postage prepaid, or by overnight courier. In addition, the Landlord may, in its
sole discretion, send such Communications to the Tenant electronically, or permit the Tenant to send such Communications to the Landlord electronically, in the manner described in this Section. Such Communications sent by personal delivery, mail or
overnight courier will be sent to the addresses on the signature page of this Lease, or to such other addresses as the Landlord and the Tenant may specify from time to time in writing. Communications shall be effective (i) if mailed, upon
the earlier of receipt or five (5) days after deposit in the U.S. mail, first class, postage prepaid, or (ii) if hand-delivered, by courier or otherwise (including telegram, lettergram or mailgram), when delivered or when delivery is
refused. Such Communications may be sent electronically by the Landlord to the Tenant (i) by transmitting the Communication to the electronic address provided by the Tenant or to such other electronic address as the Tenant may specify from time
to time in writing, or (ii) by posting the Communication on a website and sending the Tenant a notice to the Tenant’s postal address or electronic address telling the Tenant that the Communication has been posted, its location, and
providing instructions on how to view it, providing a summary with sufficient detail to inform Tenant of the nature and purpose of the Communication. Communications sent electronically to the Tenant will be effective when the Communication, or
a notice advising of its posting to a website, is sent to the Tenant’s electronic address. Such Communications may be sent electronically to the Landlord by the Tenant by transmitting the Communication to an electronic address specified by the
Landlord for the express purpose of receiving such Communications. Communications sent electronically to the Landlord will be effective when the Communication is sent to the Landlord’s electronic address. If Tenant is notified of the
identity and address of Landlord’s mortgagee or ground or underlying lessor, Tenant shall give to such mortgagee or ground or underlying lessor written notice of any default by Landlord under the terms of this Lease by registered or certified
mail, and such mortgagee or ground or underlying lessor shall be given a reasonable period of time to cure such default (but in no event less than sixty (60) days following receipt of such notice) prior to Tenant’s exercising any remedy
available to Tenant. 
 29. Tenant’s Authority. Tenant, and each of the persons executing this Lease on behalf of Tenant,
represent and warrant that (i) Tenant is a duly formed, authorized and existing limited liability company, corporation, partnership or trust (as the case may be), (ii) Tenant is qualified to do business in California, (iii) Tenant has the
full right and authority to enter into this Lease and 

  
 44 













 
to perform all of Tenant’s obligations hereunder, and (iv) each person signing on behalf of Tenant is authorized to do so. Tenant shall deliver to Landlord, upon Landlord’s
request, such certificates, resolutions, or other written assurances authorizing Tenant’s execution and delivery of this Lease, as reasonably requested by Landlord from time to time or at any time in order for Landlord to assess Tenant’s
then authority and/or ability to meet its obligations under this Lease. 
 30. Automobile Parking. 

30.1 Tenant’s Appurtenant Parking Rights. Subject to the terms and conditions contained in this Article 30, Landlord shall
make available to Tenant, 24 hours a day and 7 days a week, the number of parking spaces identified in the Basic Lease Information as the number of “Minimum Spaces”, which spaces shall be located in such parking areas located within
the Project or the Covered Parking Area, as designated by Landlord. Such parking areas currently include the uncovered surface lot behind the Building (where parking is available 24 hours per day, seven days per week) or on the ground floor of the
Covered Parking Area located across Christie Avenue (where parking is available only from 8:00 a.m. to 5:00 p.m. Monday through Friday, excluding holidays); the uncovered surface lot and the Covered Parking Area are collectively referred to herein
as the “Parking Facility”. Tenant shall at all times provide to Landlord, upon Landlord’s request, a list of all of the vehicle makes, colors and license plate numbers of all vehicles of Tenant’s employees. Tenant’s
use of the parking spaces to be made available to Tenant shall be on a non-exclusive basis in common with other tenants in the Project; and parking in such spaces shall be on a first-come-first-served,
unassigned, non-reserved basis; provided, however, six (6) of the Minimum Spaces shall be reserved visitor parking in the area shown on Exhibit A-1 attached
hereto (“Visitor Parking”). The parking spaces to be made available to Tenant shall be in locations designated by Landlord (other than Visitor Parking, which shall be fixed during the Term in the locations set forth in Exhibit A-1); and Landlord reserves the right to designate different locations from time to time within the Parking Facility without any liability to Tenant and Tenant agrees that any such designation of a
different location shall not give rise to any claims or offset against Landlord hereunder. Without limiting the generality of the foregoing, Landlord may restrict certain portions of the Parking Facility for the exclusive use of one or more tenants
of the Project (and their employees and agents) and may designate other areas in the Parking Facility to be used at large only by licensees, customers and invitees of tenants of the Project; and Landlord may in its sole and absolute discretion
restrict or prohibit the use of the Parking Facility by any vehicles other than passenger automobiles such as full-sized vans or trucks. Notwithstanding the foregoing, Landlord shall not exercise any of the
foregoing rights in a manner which would permanently reduce the total number of parking spaces available to Tenant on a non-exclusive basis to a number less than the Minimum Spaces. Tenant shall not permit any
vehicles belonging to Tenant or any of Tenant’s subtenants or any of their respective employees, agents, customers, contractors or invitees to be loaded, unloaded or parked in areas other than those designated by Landlord for such activities.
In its use of the Parking Facilities Tenant shall comply (and shall cause each of the other Tenant Parties to comply) with any and all parking regulations and rules reasonably established from time to time by Landlord or Landlord’s parking
operator provided such rules do not materially increase Tenant’s obligations under the Lease or materially decrease Tenant’s rights under the Lease. Landlord or Landlord’s parking operator shall have the right to cause to be removed
any vehicles of Tenant or of any other Tenant Parties that are parked in violation of any of the provisions of this Article 30 or of the regulations and rules then established by Landlord, and to charge all of the costs incurred by Landlord
in connection with such removal to Tenant and Tenant shall pay the amount of all such costs to Landlord as additional rent within fifteen (15) days after receipt of written demand from Landlord. Any such removal shall be without liability of
any kind to Landlord or Landlord’s parking operator or their respective employees or agents. 

  
 45 













 30.2 Parking Fee. During the Term (as may be extended), Landlord shall impose no
charge on Tenant for use of the Parking Facility. 
 30.3 Allocation of Risk. Landlord shall have no obligation to monitor the use of
the Parking Facility. The use of the Parking Facility by the employees of Tenant and its subtenants shall be at the sole risk of Tenant, its subtenants and their respective employees. Except to the extent caused by the gross negligence or willful
misconduct of Landlord, its agents, employees, or contractors, Landlord shall have no responsibility or liability for any injury or damage to any person or property by or as a result of the use of the Parking Facility by Tenant and its subtenants
and their respective employees, whether by theft, collision, criminal activity, or otherwise; and Tenant hereby assumes, for itself, its subtenants and their respective employees (without the obligation to indemnify Landlord), all risks associated
with any such occurrences in or about the Parking Facility. 
 30.4 No Assignment or Subletting of Parking. The parking rights
provided to Tenant hereunder shall be personal to Tenant and shall not be assigned, sublet or used by any other entity without Landlord’s prior written consent, except in connection with an approved assignment or subletting of or under the
Lease. 
 31. Tenant to Furnish Financial Information. Tenant shall deliver to Landlord, within ten (10) days of Landlord’s
written request, detailed financial information regarding Tenant and Tenant’s operation upon the Premises. Such information shall include income statements, balance sheets and other supporting statements or schedules as may be customarily
prepared by Tenant in the operation of its business. Landlord agrees that so long as Tenant is not in default under this Lease beyond any applicable notice and cure period, said financial information shall be requested no more frequently than one
(1) time in any twelve (12) month period. Tenant’s failure to deliver its financial information in accordance with this paragraph shall constitute a default under this Lease. Notwithstanding the foregoing to the contrary, so long as
Tenant’s common stock is publicly traded on a nationwide stock exchange domiciled in the United States, then the provisions of this Article 31 shall be inapplicable. 

32. Credit Support. 
 32.1
[Intentionally Omitted]. 
 32.2 Letter of Credit. Concurrent with Tenant’s execution and delivery of this Lease, Tenant
shall deliver to Landlord an original Letter of Credit (“Letter of Credit”) in the amount of the Letter of Credit Amount set forth in the Basic Lease Information and meeting the requirements set forth in Rider 1
attached hereto and made a part hereof. Tenant hereby acknowledges that Landlord would not enter into this Lease without Tenant’s delivery of the Letter of Credit as required herein.
