 The following Exhibits and Addenda are attached hereto and incorporated herein by this reference: 

 

			
	 ☒ EXHIBIT A - PREMISES DESCRIPTION
	  	 ☒ EXHIBIT B - DESCRIPTION OF PROJECT

	 ☒ EXHIBIT C - WORK LETTER
	  	 ☒ EXHIBIT D - COMMENCEMENT DATE

	 ☒ EXHIBIT E - RULES AND REGULATIONS
	  	 ☒ EXHIBIT F - TENANT’S PERSONAL PROPERTY

 1. Lease of Premises. Upon and subject to all of the terms and conditions hereof, Landlord hereby
leases the Premises to Tenant and Tenant hereby leases the Premises from Landlord. Landlord reserves the right to modify areas of the Project outside the Building, provided that such modifications do not materially adversely affect Tenant’s use
of the Premises for the Permitted Use. From and after the Commencement Date through the expiration of the Term, Tenant shall have access to the exclusive use of the Building and the Premises 24 hours a day, 7 days a week, except in the case of
emergencies, as the result of Legal Requirements, the performance by Landlord of any installation, maintenance or repairs, or any other temporary interruptions, and otherwise subject to the terms of this Lease. 

2. Delivery; Acceptance of Premises; Commencement Date. Landlord shall use reasonable efforts to deliver the Premises
(“Delivery” or “Deliver”) for Tenant’s construction of the Tenant Improvements pursuant to the Work Letter in Tenant Improvement Work Readiness Condition on or before the Target Commencement Date. If Landlord
fails to timely Deliver the Premises on or before the Target Commencement Date, Landlord shall not be liable to Tenant for any loss or damage resulting therefrom, and this Lease shall not be void or voidable except as provided herein.
Notwithstanding anything to the contrary contained herein, if Landlord fails to Deliver the Premises to Tenant on or before October 1, 2020 (as such date may be extended for Force Majeure delays and delays caused by Tenant, the
“Abatement Date”), then, commencing on the Rent Commencement Date, Base Rent payable with respect to the Premises shall be abated 1 day for each day from and including the Abatement Date (as such date may be amended for Force
Majeure delays and delays caused by Tenant) that Landlord fails to Deliver the Premises to Tenant. If Landlord does not Deliver the Premises by May 1, 2021, for any reason other than Force Majeure delays or delays caused by Tenant, this Lease
may be terminated by Tenant by providing written notice to Landlord, and if so terminated by Tenant in accordance with this paragraph the Lease: (a) the Security Deposit, or any balance thereof (i.e., after deducting therefrom all amounts to
which Landlord is entitled under the provisions of this Lease, if any), shall be returned to Tenant, and (b) neither Landlord nor Tenant shall have any further rights, duties or obligations under this Lease, except with respect to provisions
which expressly survive termination of this Lease. As used herein, the terms “Tenant Improvements” and “Tenant Improvement Work Readiness Condition” shall have the meanings set forth for such terms in the Work
Letter. If Tenant does not elect to terminate this Lease by May 6, 2021, such right to terminate this Lease shall be waived and this Lease shall remain in full force and effect. For the avoidance of doubt, notwithstanding anything to the
contrary contained in this Lease (including, without limitation, Section 34), any delays in Landlord’s Delivery of the Premises to Tenant arising from or related to the replacement of the Fairview Avenue Bridge by the
Seattle Department of Transportation shall constitute a Force Majeure delay. 
 The “Commencement Date” shall be the date
that Landlord Delivers the Premises to Tenant. The “Rent Commencement Date” shall be the date that is 10 months after the Commencement Date. Upon request of Landlord, Tenant shall execute and deliver a written acknowledgment of the
Commencement Date, the Rent Commencement Date and the expiration date of the Term when such are established in the form of the “Acknowledgement of Commencement Date” attached to this Lease as Exhibit D; provided,
however, Tenant’s failure to execute and deliver such acknowledgment shall not limited or otherwise affect Landlord’s rights or obligations hereunder. The “Term” of this Lease shall be the Base Term, as defined
above on the first page of this Lease and any Extension Terms which Tenant may elect pursuant to Section 40 hereof. 

Except as set forth in the Work Letter or as otherwise expressly set forth in this Lease: (i) Tenant shall accept the Premises in their
condition as of the Commencement Date; (ii) Landlord shall have no obligation for any defects in the Premises; and (iii) Tenant’s taking possession of the Premises shall be

conclusive evidence that Tenant accepts the Premises and that the Premises were in good condition at the time possession was taken. Any occupancy of the Premises by Tenant before the Commencement
Date shall be subject to all of the terms and conditions of this Lease, excluding the obligation to pay Base Rent or Operating Expenses. 

For the period of 270 consecutive days after the Commencement Date, Landlord shall, at its sole cost and expense (which shall not constitute
an Operating Expense), be responsible for any repairs that are required to be made to the Building or Building Systems (as defined in Section 13), unless Tenant or any Tenant Party was responsible for the cause of such
repair, in which case Tenant shall pay the cost. Tenant shall also be entitled to the benefit of any warranties issued to Landlord in connection with Landlord’s Work (as defined in the Work Letter). 

Tenant agrees and acknowledges that, except as otherwise expressly set forth in this Lease, neither Landlord nor any agent of Landlord has
made any representation or warranty with respect to the condition of all or any portion of the Premises or the Project, and/or the suitability of the Premises or the Project for the conduct of Tenant’s business, and Tenant waives any implied
warranty that the Premises or the Project are suitable for the Permitted Use. This Lease constitutes the complete agreement of Landlord and Tenant with respect to the subject matter hereof and supersedes any and all prior representations,
inducements, promises, agreements, understandings and negotiations which are not contained herein. Landlord in executing this Lease does so in reliance upon Tenant’s representations, warranties, acknowledgments and agreements contained herein.

 3. Rent. 
 (a)
Base Rent. Base Rent for the month in which the Rent Commencement Date occurs (or, if the Rent Commencement Date does not occur on the first day of a calendar month, Base Rent for the first full calendar month following the Rent Commencement
Date) and the Security Deposit shall be due and payable within 5 business days after the mutual execution of this Lease by Landlord and Tenant. Tenant shall pay to Landlord in advance, without demand, abatement, deduction or set-off, monthly installments of Base Rent on or before the first day of each calendar month during the Term hereof after the Rent Commencement Date, in lawful money of the United States of America, at the office of
Landlord for payment of Rent set forth above, or to such other person or at such other place as Landlord may from time to time designate in writing. Payments of Base Rent for any fractional calendar month shall be prorated. The obligation of Tenant
to pay Base Rent and other sums to Landlord and the obligations of Landlord under this Lease are independent obligations. Tenant shall have no right at any time to abate, reduce, or set-off any Rent (as
defined in Section 5) due hereunder except for any abatement as may be expressly provided in this Lease. 
 (b)
Additional Rent. In addition to Base Rent, Tenant agrees to pay to Landlord as additional rent (“Additional Rent”): (i) commencing on the Rent Commencement Date, Tenant’s Share of “Operating Expenses” (as
defined in Section 5), and (ii) any and all other amounts Tenant assumes or agrees to pay under the provisions of this Lease, including, without limitation, any and all other sums that may become due by reason of any
default of Tenant or failure to comply with the agreements, terms, covenants and conditions of this Lease to be performed by Tenant, after any applicable notice and cure period. 

4. Base Rent Adjustments. 

(a) Annual Adjustments. Base Rent shall be increased on each annual anniversary of the Rent Commencement Date (each an
“Adjustment Date”) by multiplying the Base Rent payable immediately before such Adjustment Date by the Rent Adjustment Percentage and adding the resulting amount to the Base Rent payable immediately before such Adjustment Date. Base
Rent, as so adjusted, shall thereafter be due as provided herein. Base Rent adjustments for any fractional calendar month shall be prorated.

 (b) Additional TI Allowance. In addition to the Tenant Improvement Allowance (as
defined in the Work Letter), Landlord shall, subject to the terms of the Work Letter, make available to Tenant the Additional Tenant Improvement Allowance (as defined in the Work Letter). Commencing on the Rent Commencement Date and continuing
thereafter on the first day of each month during the Base Term, Tenant shall pay the amount necessary to fully amortize the portion of the Additional Tenant Improvement Allowance actually funded by Landlord, if any, in equal monthly payments with
interest at a rate of [***]% per annum over the Base Term, which interest shall begin to accrue on the date that Landlord first disburses such Additional Tenant Improvement Allowance or any portion(s) thereof. Any of the Additional Tenant
Improvement Allowance and applicable interest remaining unpaid as of the expiration or earlier termination of the Lease shall be paid to Landlord in a lump sum at the expiration or earlier termination of this Lease. 

5. Operating Expense Payments. Landlord shall deliver to Tenant a written estimate of Operating Expenses for each calendar year during
the Term (the “Annual Estimate”), which may be revised by Landlord from time to time during such calendar year upon not less than 30 days’ written notice to Tenant; provided, however, that Landlord shall not revise the Annual
Estimate more than twice in any calendar year. Commencing on the Rent Commencement Date and continuing thereafter on the first day of each month during the Term, Tenant shall pay Landlord an amount equal to 1/12th of Tenant’s Share of the
Annual Estimate. Payments for any fractional calendar month shall be prorated. 
 The term “Operating Expenses” means all
costs and expenses of any kind or description whatsoever incurred or accrued each calendar year by Landlord with respect to the Project (including, without duplication, Taxes (as defined in Section 9), capital
repairs, improvements and replacements amortized over the lesser of 10 years and the useful life of such capital repairs, improvements or replacements, transportation services (including costs associated with Landlord’s operation of or
participation in a shuttle service), and the costs of Landlord’s third party property manager (not to exceed [***]% of Base Rent) or, if there is no third party property manager, administration rent in the amount of [***]% of Base Rent),
excluding only: 
 (a) the original construction costs of the Project and renovation prior to the date of the Lease and costs of correcting
defects in such original construction or renovation; 
 (b) capital expenditures for expansion of the Project; 

(c) interest, principal payments of Mortgage (as defined in Section 27) debts of Landlord, financing costs and
amortization of funds borrowed by Landlord, whether secured or unsecured; 
 (d) depreciation of the Project (except for capital
improvements, the cost of which are includable in Operating Expenses); 
 (e) Taxes to be paid directly by Tenant, whether or not actually
paid; 
 (f) salaries, wages, benefits and other compensation paid to officers and employees of Landlord who are not assigned in whole or in
part to the operation, management, maintenance or repair of the Project; 
 (g) general organizational, administrative and overhead costs
relating to maintaining Landlord’s existence, either as a corporation, partnership, or other entity, including general corporate, legal and accounting expenses; 

(h) costs and expenses, including legal fees, incurred in connection with negotiations or disputes with employees, consultants, management
agents, leasing agents, purchasers or mortgagees of the Building; 

  
 

 
  

 Certain information, as identified by [***], has been excluded from this agreement because it (i) is not
material and (ii) would be competitively harmful if publicly disclosed.

 (i) costs incurred by Landlord due to the violation by Landlord, its employees, agents or
contractors of any Legal Requirement (as defined in Section 7); 
 (j) penalties, fines or interest incurred as a
result of Landlord’s inability or failure to make payment of Taxes and/or to file any tax or informational returns when due, or from Landlord’s failure to make any payment of Taxes required to be made by Landlord hereunder before
delinquency; 
 (k) overhead and profit increment paid to Landlord or to subsidiaries or affiliates of Landlord for goods and/or services in
or to the Project to the extent the same exceeds the costs of such goods and/or services rendered by unaffiliated third parties on a competitive basis; 

(l) costs of Landlord’s charitable or political contributions, or of fine art maintained at the Project; 

(m) costs incurred in the sale or refinancing of the Project; 

(n) net income taxes of Landlord or the owner of any interest in the Project, franchise, capital stock, gift, estate or inheritance taxes or
any federal, state or local documentary taxes imposed against the Project or any portion thereof or interest therein; and 
 (o) any expenses
otherwise includable within Operating Expenses to the extent actually reimbursed by persons other than tenants of the Project under leases for space in the Project. 

In addition, notwithstanding anything to the contrary contained in this Lease, Operating Expenses incurred or accrued by Landlord with respect
to any capital improvements which are reasonably expected by Landlord to reduce overall Operating Expenses (for example, without limitation, by reducing energy usage at the Project) (the “Energy Savings Costs”) shall be amortized
over a period of years equal to the least of (A) 7 years, (B) the useful life of such capital items, or (C) the quotient of (i) the Energy Savings Costs, divided by (ii) the annual amount of Operating Expenses reasonably expected
by Landlord to be saved as a result of such capital improvements. 
 Within 90 days after the end of each calendar year (or such longer
period as may be reasonably required, but in no event more than 120 days), Landlord shall furnish to Tenant a statement (an “Annual Statement”) showing in reasonable detail (along with, upon written request from Tenant, supporting
documentation): (a) the total and Tenant’s Share of actual Operating Expenses for the previous calendar year, and (b) the total of Tenant’s payments of Operating Expenses for such year. If Tenant’s Share of actual Operating
Expenses for such year exceeds Tenant’s payments of Operating Expenses for such year, the excess shall be due and payable by Tenant as Rent within 30 days after delivery of such Annual Statement to Tenant. If Tenant’s payments of Operating
Expenses for such year exceed Tenant’s Share of actual Operating Expenses for such year Landlord shall pay the excess to Tenant within 30 days after delivery of such Annual Statement, except that after the expiration, or earlier termination of
the Term or if Tenant is delinquent in its obligation to pay Rent, Landlord shall pay the excess to Tenant after deducting all other amounts due Landlord. Landlord’s and Tenant’s obligations to pay any overpayments or deficiencies due
pursuant to this paragraph shall survive the expiration or earlier termination of this Lease. 
 The Annual Statement shall be final and
binding upon Tenant unless Tenant, within 90 days after Tenant’s receipt thereof, contests any item therein by giving written notice to Landlord, specifying each item contested and the reason therefor. If, during such 90 day period, Tenant
reasonably and in good faith questions or contests the accuracy of Landlord’s statement of Tenant’s Share of Operating Expenses, Landlord will provide Tenant with access to Landlord’s books and records relating to the operation of the
Project and such information as Landlord reasonably determines to be responsive to Tenant’s questions (the “Expense Information”). If after Tenant’s review of such Expense Information, Landlord and Tenant cannot agree upon
the amount of Tenant’s Share of Operating Expenses, then Tenant shall have the right to have an independent regionally recognized public accounting firm selected

by Tenant and approved by Landlord (which approval shall not be unreasonably withheld or delayed), working pursuant to a fee arrangement other than a contingent fee (at Tenant’s sole cost
and expense), audit and/or review the Expense Information for the year in question (the “Independent Review”). The results of any such Independent Review shall be binding on Landlord and Tenant. If the Independent Review shows that
the payments actually made by Tenant with respect to Operating Expenses for the calendar year in question exceeded Tenant’s Share of Operating Expenses for such calendar year, Landlord shall at Landlord’s option either (i) credit the
excess amount to the next succeeding installments of estimated Operating Expenses or (ii) pay the excess to Tenant within 30 days after delivery of such statement, except that after the expiration or earlier termination of this Lease or if
Tenant is delinquent in its obligation to pay Rent, Landlord shall pay the excess to Tenant after deducting all other amounts due Landlord. If the Independent Review shows that Tenant’s payments with respect to Operating Expenses for such
calendar year were less than Tenant’s Share of Operating Expenses for the calendar year, Tenant shall pay the deficiency to Landlord within 30 days after delivery of such statement. If the Independent Review shows that Tenant has overpaid with
respect to Operating Expenses by more than 5% then Landlord shall reimburse Tenant for all costs incurred by Tenant for the Independent Review. Operating Expenses for the calendar years in which Tenant’s obligation to share therein begins and
ends shall be prorated. 
 “Tenant’s Share” shall be the percentage set forth on the first page of this Lease
as Tenant’s Share. Base Rent, Tenant’s Share of Operating Expenses and all other amounts payable by Tenant to Landlord hereunder are collectively referred to herein as “Rent.”  

6. Security Deposit. Tenant shall deposit with Landlord, upon delivery of an executed copy of this Lease to Landlord, a security deposit
(the “Security Deposit”) for the performance of all of Tenant’s obligations hereunder in the amount set forth on page 1 of this Lease, which Security Deposit shall be in the form of an unconditional and irrevocable letter of
credit (the “Letter of Credit”): (i) in form and substance satisfactory to Landlord, (ii) naming Landlord as beneficiary, (iii) expressly allowing Landlord to draw upon it at any time from time to time by delivering to the
issuer notice that Landlord is entitled to draw thereunder, (iv) issued by an FDIC-insured financial institution satisfactory to Landlord, and (v) redeemable by presentation of a sight draft in the state of Landlord’s choice. If
Tenant does not provide Landlord with a substitute Letter of Credit complying with all of the requirements hereof at least 10 days before the stated expiration date of any then current Letter of Credit, Landlord shall have the right to draw the full
amount of the current Letter of Credit and hold the funds drawn in cash without obligation for interest thereon as the Security Deposit. The Security Deposit shall be held by Landlord as security for the performance of Tenant’s obligations
under this Lease. The Security Deposit is not an advance rental deposit or a measure of Landlord’s damages in case of Tenant’s default. Upon each occurrence of a Default (as defined in Section 20), Landlord may
use all or any part of the Security Deposit to pay delinquent payments due under this Lease, future rent damages, and the cost of any damage, injury, expense or liability caused by such Default, without prejudice to any other remedy provided herein
or provided by law. Landlord’s right to use the Security Deposit under this Section 6 includes the right to use the Security Deposit to pay future rent damages following the termination of this Lease pursuant to
Section 21(c) below. Upon any use of all or any portion of the Security Deposit, Tenant shall pay Landlord on demand the amount that will restore the Security Deposit to the amount set forth on Page 1 of this Lease. Tenant
hereby waives the provisions of any law, now or hereafter in force which provide that Landlord may claim from a security deposit only those sums reasonably necessary to remedy defaults in the payment of Rent, to repair damage caused by Tenant or to
clean the Premises, it being agreed that Landlord may, in addition, claim 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. Upon bankruptcy or other debtor-creditor proceedings against Tenant, the Security Deposit shall be deemed to be applied first to the payment of Rent and other charges due Landlord for periods prior to the filing
of such proceedings. If Tenant shall fully perform every provision of this Lease to be performed by Tenant, the Security Deposit, or any balance thereof (i.e., after deducting therefrom all amounts to which Landlord is entitled under the provisions
of this Lease), shall be returned to Tenant (or, at Landlord’s option, to the last assignee of Tenant’s interest hereunder) within 90 days after the expiration or earlier termination of this Lease.

 If Landlord transfers its interest in the Project or this Lease, Landlord shall either
(a) transfer any Security Deposit then held by Landlord to a person or entity assuming Landlord’s obligations under this Section 6, or (b) return to Tenant any Security Deposit then held by Landlord and
remaining after the deductions permitted herein. Upon such transfer to such transferee or the return of the Security Deposit to Tenant, Landlord shall have no further obligation with respect to the Security Deposit, and Tenant’s right to the
return of the Security Deposit shall apply solely against Landlord’s transferee. Landlord’s obligation respecting the Security Deposit is that of a debtor, not a trustee, and no interest shall accrue thereon. 

7. Use. The Premises shall be used solely for the Permitted Use set forth in the basic lease provisions on page 1 of this Lease, and in
compliance with all laws, orders, judgments, ordinances, regulations, codes, directives, permits, licenses, covenants and restrictions now or hereafter applicable to the Premises, and to the use and occupancy thereof, including, without limitation,
the Americans With Disabilities Act, 42 U.S.C. § 12101, et seq. (together with the regulations promulgated pursuant thereto, “ADA”) (collectively, “Legal Requirements” and each, a “Legal
Requirement”). Tenant shall, upon 5 days’ written notice from Landlord, discontinue any use of the Premises which is declared by any Governmental Authority (as defined in Section 9) having jurisdiction to be a
violation of a Legal Requirement. Tenant will not use or permit the Premises to be used for any purpose or in any manner that would void Tenant’s or Landlord’s insurance, increase the insurance risk, or cause the disallowance of any
sprinkler or other credits. Tenant shall not permit any part of the Premises to be used as a “place of public accommodation”, as defined in the ADA or any similar legal requirement. Tenant shall reimburse Landlord promptly upon demand for
any additional premium charged for any such insurance policy by reason of Tenant’s failure to comply with the provisions of this Section or otherwise caused by Tenant’s use and/or occupancy of the Premises. Tenant will use the Premises in
a careful, safe and proper manner and will not commit or permit waste, overload the floor or structure of the Premises, subject the Premises to use that would damage the Premises. Tenant shall cause any equipment or machinery to be installed in the
Premises so as to reasonably prevent sounds or vibrations from the Premises from extending unreasonably outside the Premises. Tenant shall not place any machinery or equipment which would overload the floor in or upon the Premises or transport or
move such items in the Project elevators without the prior written consent of Landlord. Except as may be provided under the Work Letter, Tenant shall not, without the prior written consent of Landlord, use the Premises in any manner which will
require ventilation, air exchange, heating, gas, steam, electricity or water beyond the existing capacity of the Project. 
 Landlord shall,
at Landlord’s sole cost and expense, be responsible for the compliance of Landlord’s Work (as defined in the Work Letter) with Legal Requirements as of the date that Landlord substantially completes Landlord’s Work. Except as provided
in the immediately preceding sentence, Tenant, at its sole expense, shall make any alterations or modifications to the Project that are required by Legal Requirements (including, without limitation, compliance of the Premises with the ADA) related
to Tenant’s particular use or occupancy of the Premises, the Tenant Improvements and any Alterations. Notwithstanding any other provision herein to the contrary, subject to the first sentence of this paragraph, Tenant shall be responsible for
any and all demands, claims, liabilities, losses, costs, expenses, actions, causes of action, damages or judgments, and all reasonable expenses incurred in investigating or resisting the same (including, without limitation, reasonable
attorneys’ fees, charges and disbursements and costs of suit) (collectively, “Claims”) arising out of or in connection with Tenant’s compliance with Legal Requirements, and except for Landlord’s Work, Tenant shall
indemnify, defend, hold and save Landlord harmless from and against any and all Claims arising out of or in connection with any failure of the Premises to comply with any Legal Requirement. 

Tenant acknowledges that Landlord may, but shall not be obligated to, seek to obtain Leadership in Energy and Environmental Design (LEED),
WELL Building Standard, or other similar “green” certification with respect to the Project and/or the Premises, and Tenant agrees to reasonably cooperate with Landlord, at no material cost to Tenant, and to provide such information and/or
documentation as Landlord may reasonably request, in connection therewith.

 8. Holding Over. If, with Landlord’s express written consent, Tenant retains
possession of the Premises after the termination of the Term, (i) unless otherwise agreed in such written consent, such possession shall be subject to termination by Landlord at any time upon 30 days’ notice to Tenant, (ii) all of the
other terms and provisions of this Lease (including, without limitation, the adjustment of Base Rent pursuant to Section 4 hereof) shall remain in full force and effect (excluding any expansion or renewal option or other
similar right or option) during such holdover period, (iii) Tenant shall continue to pay Base Rent in the amount payable upon the date of the expiration or earlier termination of this Lease or such other amount as Landlord may indicate, in
Landlord’s sole and absolute discretion, in such written consent, and (iv) all other payments shall continue under the terms of this Lease. If Tenant remains in possession of the Premises after the expiration or earlier termination of the
Term without the express written consent of Landlord, (A) Tenant shall become a tenant at sufferance upon the terms of this Lease except that the monthly rental shall be equal to 150% of Rent in effect during the last 30 days of the Term, and
(B) Tenant shall be responsible for all damages suffered by Landlord resulting from or occasioned by Tenant’s holding over, including consequential damages. No holding over by Tenant, whether with or without consent of Landlord, shall
operate to extend this Lease except as otherwise expressly provided, and this Section 8 shall not be construed as consent for Tenant to retain possession of the Premises. Acceptance by Landlord of Rent after the expiration
of the Term or earlier termination of this Lease shall not result in a renewal or reinstatement of this Lease. 
 9. Taxes. Landlord
shall pay, as part of Operating Expenses, all taxes, levies, fees, assessments and governmental charges of any kind, existing as of the Commencement Date or thereafter enacted (collectively referred to as “Taxes”), imposed by any
federal, state, regional, municipal, local or other governmental authority or agency, including, without limitation, quasi-public agencies (collectively, “Governmental Authority”) during the Term, including, without limitation, all
Taxes: (i) imposed on or measured by or based, in whole or in part, on rent payable to (or gross receipts received by) Landlord under this Lease and/or from the rental by Landlord of the Project or any portion thereof, or (ii) based on the
square footage, assessed value or other measure or evaluation of any kind of the Premises or the Project , or (iii) assessed or imposed by or on the operation or maintenance of any portion of the Premises or the Project, including parking, or
(iv) assessed or imposed by, or at the direction of, or resulting from Legal Requirements, or interpretations thereof, promulgated by any Governmental Authority, or (v) imposed as a license or other fee, charge, tax, or assessment on
Landlord’s business or occupation of leasing space in the Project. Landlord may contest by appropriate legal proceedings the amount, validity, or application of any Taxes or liens securing Taxes. Taxes shall not include any net income taxes
imposed on Landlord except to the extent such net income taxes are in substitution for any Taxes payable hereunder. If any such Tax is levied or assessed directly against Tenant, then Tenant shall be responsible for and shall pay the same at such
times and in such manner as the taxing authority shall require. Tenant shall pay, prior to delinquency, any and all Taxes levied or assessed against any personal property or trade fixtures placed by Tenant in the Premises, whether levied or assessed
against Landlord or Tenant. If any Taxes on Tenant’s personal property or trade fixtures are levied against Landlord or Landlord’s property, or if the assessed valuation of the Project is increased by a value attributable to improvements
in or alterations to the Premises, whether owned by Landlord or Tenant and whether or not affixed to the real property so as to become a part thereof, higher than the base valuation on which Landlord from time-to-time allocates Taxes to the Project, Landlord shall have the right, but not the obligation, to pay such Taxes. Landlord’s determination of any excess assessed valuation shall be binding and
conclusive, absent manifest error. The amount of any such payment by Landlord shall constitute Additional Rent due from Tenant to Landlord immediately upon demand. 

10. Parking. Subject to all matters of record, Force Majeure, a Taking (as defined in Section 19 below) and
the exercise by Landlord of its rights hereunder, Tenant shall have the right to use and shall be required to pay Parking Charges for all of the parking spaces located in the subsurface parking areas of the Building, subject in each case to
Landlord’s rules and regulations and the payment, commencing on the Rent Commencement Date, of $[***] per month for each parking space allocated to Tenant plus applicable taxes (“Parking Charges”). On each annual anniversary of
the Rent Commencement Date, the per parking space Parking Charges payable by Tenant shall be increased annually by Landlord to the then-current market rate for parking spaces in similar parking garages serving

Class A laboratory/office buildings in the South Lake Union area of Seattle, as reasonably determined by Landlord. Upon written request from Tenant, Landlord shall provide to Tenant any
supporting documentation upon which Landlord’s determination of the then-current market rates is based. Landlord shall not be responsible for enforcing Tenant’s parking rights against any third parties. 

Subject to compliance with Legal Requirements, Landlord shall, at Landlord’s cost and expense, install prior to the Rent Commencement
Date, and, as part of Operating Expenses, power and maintain, approximately 2 dual-charging electric vehicle charging stations in the parking areas of the Project. 

11. Utilities, Services. Tenant shall contract directly with utility providers for all water, electricity, heat, light, power, sewer,
and other utilities (including gas and fire sprinklers to the extent the Project is plumbed for such services), janitorial services and refuse and trash collection (collectively, “Utilities”) required and/or utilized by Tenant
during the Term. Upon Tenant’s request, Landlord shall assist Tenant, at no material cost to Landlord, in facilitating Tenant’s establishment of services with the applicable Utility providers. All Utilities to the Premises shall be
separately metered and Tenant shall pay directly to such Utility providers prior to delinquency for all such Utilities furnished to Tenant or the Project during the Term and shall pay for all maintenance charges for Utilities, and any storm sewer
charges or other similar charges for Utilities imposed by any Governmental Authority or Utility provider, and any taxes, penalties, surcharges or similar charges thereon. To the extent that any Utilities, maintenance charges for Utilities, any storm
sewer charges or other similar charges for Utilities imposed by any Governmental Authority or Utility provider, or any taxes, penalties, surcharges or similar charges are paid for by Landlord, Tenant shall reimburse Landlord for such costs as
Operating Expenses. No interruption or failure of Utilities, from any cause whatsoever other than Landlord’s willful misconduct, shall result in eviction or constructive eviction of Tenant, termination of this Lease or the abatement of Rent.

 Tenant agrees, to extent required by Legal Requirements or any Governmental Authority, to provide Landlord with access to Tenant’s
water and/or energy usage data on a monthly basis, either by providing Tenant’s applicable utility login credentials to Landlord’s Measurabl online portal, or by another delivery method reasonably agreed to by Landlord and Tenant. The
costs and expenses incurred by Landlord in connection with receiving and analyzing such water and/or energy usage data (including, without limitation, as may be required pursuant to applicable Legal Requirements) shall be included as part of
Operating Expenses. 
 12. Alterations and Tenant’s Property. Any alterations, additions, or improvements made to the Premises by
or on behalf of Tenant, including additional locks or bolts of any kind or nature upon any doors or windows in the Premises, but excluding installation, removal or realignment of furniture systems (other than removal of furniture systems owned or
paid for by Landlord) not involving any modifications to the structure or connections (other than by ordinary plugs or jacks) to Building Systems (as defined in Section 13) (“Alterations”) shall be subject
to Landlord’s prior written consent, which may be given or withheld in Landlord’s sole discretion if any such Alteration affects the structure or Building Systems and shall not be otherwise unreasonably withheld, conditioned or delayed.
Tenant may construct nonstructural Alterations in the Premises without Landlord’s prior approval if the aggregate cost of all such work in any 12 month period does not exceed $150,000 (a “Notice-Only Alteration”), provided
Tenant notifies Landlord in writing of such intended Notice-Only Alteration, and such notice shall be accompanied by plans, specifications, work contracts and such other information concerning the nature and cost of the Notice-Only Alteration as may
be reasonably requested by Landlord, which notice and accompanying materials shall be delivered to Landlord not less than 15 business days in advance of any proposed construction. If Landlord approves any Alterations, Landlord may impose such
conditions on Tenant in connection with the commencement, performance and completion of such Alterations as Landlord may deem appropriate in Landlord’s reasonable discretion. Any request for approval shall be in writing, delivered not less than
15 business days in advance of any proposed construction, and accompanied by plans, specifications, bid proposals, work contracts and such other information concerning the nature and cost of the alterations as may be reasonably requested by
Landlord, including the identities and mailing addresses of all persons performing work or supplying materials. Landlord’s right to review plans and specifications and to monitor construction shall be solely for its own benefit, and Landlord
shall have no duty to ensure that such plans and specifications or construction comply with

applicable Legal Requirements. Tenant shall cause, at its sole cost and expense, all Alterations to comply with insurance requirements and with Legal Requirements and shall implement at its sole
cost and expense any alteration or modification required by Legal Requirements as a result of any Alterations. Tenant shall pay to Landlord, as Additional Rent, on demand an amount equal to [***]% of all hard costs incurred by Tenant or its
contractors or agents in connection with any Alteration to cover Landlord’s overhead and expenses for plan review, coordination, scheduling and supervision. Before Tenant begins any Alteration, Landlord may post on and about the Premises
notices of non-responsibility pursuant to applicable law. Tenant shall reimburse Landlord for, and indemnify and hold Landlord harmless from, any expense incurred by Landlord by reason of faulty work done by
Tenant or its contractors, delays caused by such work, or inadequate cleanup. 
 Tenant shall furnish security or make other arrangements
satisfactory to Landlord to assure payment for the completion of all Alterations work free and clear of liens, and shall provide (and cause each contractor or subcontractor to provide) certificates of insurance for workers’ compensation and
other coverage in amounts and from an insurance company satisfactory to Landlord protecting Landlord against liability for personal injury or property damage during construction. Upon completion of any Alterations, Tenant shall deliver to Landlord:
(i) sworn statements setting forth the names of all contractors and subcontractors who did the work and final lien waivers from all such contractors and subcontractors; and (ii) “as built” plans for any such Alteration. 

Except for Removable Installations (as hereinafter defined), all Installations (as hereinafter defined) shall be and shall remain the property
of Landlord during the Term and following the expiration or earlier termination of the Term, shall not be removed by Tenant at any time during the Term, and shall remain upon and be surrendered with the Premises as a part thereof. Notwithstanding
the foregoing, Landlord may, at the time its approval of any such Installation is requested, or at the time it receives notice of a Notice-Only Alteration, notify Tenant that Landlord requires that Tenant remove such Installation upon the expiration
or earlier termination of the Term, in which event Tenant shall remove such Installation in accordance with the immediately succeeding sentence. Upon the expiration or earlier termination of the Term, Tenant shall remove (i) all wires, cables
or similar equipment which Tenant has installed in the Premises or in the risers or plenums of the Building, (ii) any Installations for which Landlord has given Tenant notice of removal in accordance with the immediately preceding sentence, and
(iii) all of Tenant’s Property (as hereinafter defined), and Tenant shall restore and repair any damage caused by or occasioned as a result of such removal, including, without limitation, capping off all such connections behind the walls
of the Premises and repairing any holes. During any restoration period beyond the expiration or earlier termination of the Term, Tenant shall pay Rent to Landlord as provided herein as if said space were otherwise occupied by Tenant. If Landlord is
requested by Tenant or any lender, lessor or other person or entity claiming an interest in any of Tenant’s Property to waive any lien Landlord may have against any of Tenant’s Property, and Landlord consents to such waiver, then Landlord
shall be entitled to be paid as administrative rent a fee of $1,000 per occurrence for its time and effort in preparing and negotiating such a waiver of lien. 

For purposes of this Lease, (x) “Removable Installations” means any items listed on Exhibit F attached hereto and any
items agreed by Landlord in writing to be included on Exhibit F in the future, (y) ”Tenant’s Property” means Removable Installations and, other than Installations, any personal property or equipment of Tenant that
may be removed without material damage to the Premises, and (z) ”Installations” means all property of any kind paid for with the TI Fund, all Alterations, all fixtures, and all partitions, hardware, built-in machinery, built-in casework and cabinets and other similar additions, equipment, property and improvements built into the Premises so as to become an integral part
of the Premises, including, without limitation, fume hoods which penetrate the roof or plenum area, built-in cold rooms, built-in warm rooms, walk-in cold rooms, walk-in warm rooms, deionized water systems, glass washing equipment, autoclaves, chillers, built-in plumbing,
electrical and mechanical equipment and systems, and any power generator and transfer switch. 
 Notwithstanding anything to the contrary
contained herein, Tenant shall not be required to remove or restore the Tenant Improvements constructed pursuant to the Work Letter at the expiration or earlier termination of this Lease, nor shall Tenant have the right to remove such Tenant
Improvements at any time other than in accordance with this Section 12. 

  
 

 

 Certain information, as identified by [***], has been excluded from this agreement because it (i) is not
material and (ii) would be competitively harmful if publicly disclosed.

 13. Landlord’s Repairs. Landlord, as an Operating Expense (except as otherwise
provided in the penultimate paragraph of Section 2), shall maintain all of the structural, exterior, parking and areas of the Project exterior to the Building, including HVAC, plumbing, fire sprinklers, elevators and all
other building systems serving the Premises and other portions of the Project (“Building Systems”) in good repair, reasonable wear and tear and uninsured losses and damages caused by Tenant, or by any of Tenant, or by any of
Tenant’s assignees, sublessees, licensees, agents, servants, employees, invitees and contractors (or any of Tenant’s assignees, sublessees and/or licensees respective agents, servants, employees, invitees and contractors) (collectively,
“Tenant Parties”) excluded. Losses and damages caused by Tenant or any Tenant Party shall be repaired by Landlord, to the extent not covered by insurance, at Tenant’s sole cost and expense. Landlord reserves the right to stop
Building Systems services when necessary (i) by reason of accident or emergency, or (ii) for planned repairs, alterations or improvements, which are, in the reasonable judgment of Landlord, desirable or necessary to be made, until said
repairs, alterations or improvements shall have been completed. Landlord shall have no responsibility or liability for failure to supply Building Systems services during any such period of interruption; provided, however, that Landlord
shall, except in case of emergency, give Tenant 72 hours advance notice of any planned stoppage of Building Systems services for routine maintenance, repairs, alterations or improvements. Tenant shall promptly give Landlord written notice of any
repair required by Landlord pursuant to this Section, after which Landlord shall make a commercially reasonable effort to effect such repair. Landlord shall not be liable for any failure to make any repairs or to perform any maintenance unless such
failure shall persist for an unreasonable time after Tenant’s written notice of the need for such repairs or maintenance. Tenant waives its rights under any state or local law to terminate this Lease or to make such repairs at Landlord’s
expense and agrees that the parties’ respective rights with respect to such matters shall be solely as set forth herein. Repairs required as the result of fire, earthquake, flood, vandalism, war, or similar cause of damage or destruction shall
be controlled by Section 18. 
 Notwithstanding anything to the contrary contained herein, Tenant shall have a
self-help right pursuant to Section 31. 
 14. Tenant’s Repairs. Subject to
Section 13 hereof, Tenant, at its expense, shall repair, replace and maintain in good condition all portions of the Premises, including, without limitation, entries, doors, ceilings, interior windows, interior walls, and
the interior side of demising walls. Should Tenant fail to make any such repair or replacement or fail to maintain the Premises, Landlord shall give Tenant notice of such failure. If Tenant fails to commence cure of such failure within 10 days of
Landlord’s notice, and thereafter diligently prosecute such cure to completion, Landlord may perform such work and shall be reimbursed by Tenant for the reasonable costs incurred by Landlord in connection with such work within 10 days after
demand (along with delivery of an invoice and reasonable supporting documentation therefor) therefor; provided, however, that if such failure by Tenant creates or could create an emergency, Landlord may immediately commence cure of such failure and
shall thereafter be entitled to recover the costs of such cure from Tenant. Subject to Sections 17 and 18, Tenant shall bear the full uninsured cost of any repair or replacement to any part of the Project that results from damage
caused by Tenant or any Tenant Party and any repair that benefits only the Premises. 
 15. Mechanic’s Liens. Tenant shall
discharge, by bond or otherwise, any mechanic’s lien filed against the Premises or against the Project for work claimed to have been done for, or materials claimed to have been furnished to, Tenant within 10 days after Tenant receives notice of
the filing thereof, at Tenant’s sole cost and shall otherwise keep the Premises and the Project free from any liens arising out of work performed, materials furnished or obligations incurred by Tenant. Should Tenant fail to discharge any lien
described herein, Landlord shall have the right, but not the obligation, to pay such claim or post a bond or otherwise provide security to eliminate the lien as a claim against title to the Project and the cost thereof shall be immediately due from
Tenant as Additional Rent. If Tenant shall lease or finance the acquisition of office equipment, furnishings, or other personal property of a removable nature utilized by Tenant in the operation of Tenant’s business, Tenant warrants that any

  
 

 

			
	Net Laboratory	  	1165 Eastlake/Adaptive - Page

Uniform Commercial Code Financing Statement filed as a matter of public record by any lessor or creditor of Tenant will upon its face or by exhibit thereto indicate that such Financing Statement
is applicable only to removable personal property of Tenant located within the Premises. In no event shall the address of the Project be furnished on the statement without qualifying language as to applicability of the lien only to removable
personal property, located in an identified suite held by Tenant. 
 16. Indemnification. Tenant hereby indemnifies and agrees to
defend, save and hold Landlord, its officers, directors, employees, managers, agents, and lease signators (collectively, “Landlord Indemnified Parties”) harmless from and against any and all Claims for injury or death to persons or
damage to property occurring within or about the Premises or the Project arising directly or indirectly out of use or occupancy of the Premises or the Project by Tenant or any Tenant Party (including, without limitation, any act, omission or neglect
by Tenant or any Tenant’s Parties in or about the Premises or at the Project) or the a breach or default by Tenant in the performance of any of its obligations hereunder, except to the extent caused by the willful misconduct or negligence of
Landlord Indemnified Parties. Landlord shall not be liable to Tenant for, and Tenant assumes all risk of damage to, personal property (including, without limitation, loss of records kept within the Premises). Tenant further waives any and all Claims
for injury to Tenant’s business or loss of income relating to any such damage or destruction of personal property (including, without limitation, any loss of records). Landlord Indemnified Parties shall not be liable for any damages arising
from any act, omission or neglect of any tenant in the Project or of any other third party. 
 17. Insurance. Landlord shall maintain
all risk property and, if applicable, sprinkler damage insurance covering the full replacement cost of the Project. Landlord shall further procure and maintain commercial general liability insurance with a single loss limit of not less than
$2,000,000 for bodily injury and property damage with respect to the Project. Landlord may, but is not obligated to, maintain such other insurance and additional coverages as it may deem necessary, including, but not limited to, flood, environmental
hazard and earthquake, loss or failure of building equipment, errors and omissions, rental loss during the period of repair or rebuilding, workers’ compensation insurance and fidelity bonds for employees employed to perform services and
insurance for any improvements installed by Tenant or which are in addition to the standard improvements customarily furnished by Landlord without regard to whether or not such are made a part of the Project. All such insurance shall be included as
part of the Operating Expenses. The Project may be included in a blanket policy (in which case the cost of such insurance allocable to the Project will be determined by Landlord based upon the insurer’s cost calculations). Tenant shall also
reimburse Landlord for any increased premiums or additional insurance which Landlord reasonably deems necessary as a result of Tenant’s use of the Premises.  

Tenant, at its sole cost and expense, shall maintain during the Term: special form or all-risk
property insurance with business interruption and extra expense coverage, covering the full replacement cost of all property and improvements installed or placed in the Premises by Tenant at Tenant’s expense; workers’ compensation
insurance with no less than the minimum limits required by law; employer’s liability insurance with employers liability limits of $1,000,000 bodily injury by accident – each accident, $1,000,000 bodily injury by disease – policy
limit, and $1,000,000 bodily injury by disease – each employee; and commercial general liability insurance, with a minimum limit of not less than $5,000,000 per occurrence for bodily injury and property damage with respect to the Premises. The
commercial general liability insurance maintained by Tenant shall name Alexandria Real Estate Equities, Inc., and Landlord, its officers, directors, employees, and managers (collectively, “Landlord Insured Parties”), as additional
insureds; insure on an occurrence and not a claims-made basis; be issued by insurance companies which have a rating of not less than policyholder rating of A and financial category rating of at least Class X in “Best’s Insurance
Guide”; shall not be cancelable for nonpayment of premium unless 30 days prior written notice shall have been given to Landlord from the insurer; not contain a hostile fire exclusion; contain a contractual liability endorsement; and provide
primary coverage to Landlord Insured Parties (any policy issued to Landlord Insured Parties providing duplicate or similar coverage shall be deemed excess over Tenant’s policies, regardless of limits). Copies of such policies (if requested by
Landlord), or certificates of insurance showing the limits of coverage required hereunder and showing Landlord as an additional insured, along with reasonable evidence of the payment of premiums for the applicable period, shall be delivered to
Landlord by Tenant prior to (i) the earlier to occur of (x) the 

  
 

 

			
	Net Laboratory	  	1165 Eastlake/Adaptive - Page 
13

  

 
Commencement Date, or (y) the date that Tenant accesses the Premises under this Lease, and (ii) each renewal of said insurance. Tenant’s policy may be a “blanket policy”
with an aggregate per location endorsement which specifically provides that the amount of insurance shall not be prejudiced by other losses covered by the policy. Tenant shall, at least 5 days prior to the expiration of such policies, furnish
Landlord with renewal certificates. Notwithstanding anything to the contrary contained herein, the minimum coverage limits set forth herein may be satisfied by Tenant using a combination of commercial general liability and umbrella policies. 

In each instance where insurance is to name Landlord as an additional insured, Tenant shall upon written request of Landlord also designate
and furnish certificates so evidencing Landlord as additional insured to: (i) any lender of Landlord holding a security interest in the Project or any portion thereof, (ii) the landlord under any lease wherein Landlord is tenant of the
real property on which the Project is located, if the interest of Landlord is or shall become that of a tenant under a ground or other underlying lease rather than that of a fee owner, and/or (iii) any management company retained by Landlord to
manage the Project. 
 The property insurance obtained by Landlord and Tenant shall include a waiver of subrogation by the insurers and all
rights based upon an assignment from its insured, against Landlord or Tenant, and their respective officers, directors, employees, managers, agents, invitees and contractors (“Related Parties”), in connection with any loss or damage
thereby insured against. Neither party nor its respective Related Parties shall be liable to the other for loss or damage caused by any risk insured against under property insurance required to be maintained hereunder, and each party waives any
claims against the other party, and its respective Related Parties, for such loss or damage. The failure of a party to insure its property shall not void this waiver. Landlord and its respective Related Parties shall not be liable for, and Tenant
hereby waives all claims against such parties for, business interruption and losses occasioned thereby sustained by Tenant or any person claiming through Tenant resulting from any accident or occurrence in or upon the Premises or the Project from
any cause whatsoever. If the foregoing waivers shall contravene any law with respect to exculpatory agreements, the liability of Landlord or Tenant shall be deemed not released but shall be secondary to the other’s insurer. 

Landlord may require insurance policy limits to be raised to conform with requirements of Landlord’s lender and/or to bring coverage
limits to levels then being generally required of new tenants within the Project; provided, however, that the increased amount of coverage is consistent with coverage amounts then being required by institutional owners of similar projects with
tenants occupying similar size premises in the geographical area in which the Project is located. 
 18. Restoration. If, at any time
during the Term, the Project or the Premises are damaged or destroyed by a fire or other insured casualty, Landlord shall notify Tenant within 60 days after discovery of such damage as to the amount of time Landlord reasonably estimates it will take
to restore the Project or the Premises, as applicable (the “Restoration Period”). If the Restoration Period is estimated to exceed 12 months (the “Maximum Restoration Period”), Landlord may, in such notice, elect to
terminate this Lease as of the date that is 75 days after the date of discovery of such damage or destruction; provided, however, that notwithstanding Landlord’s election to restore, Tenant may elect to terminate this Lease by written
notice to Landlord delivered within 10 business days of receipt of a notice from Landlord estimating a Restoration Period for the Premises longer than the Maximum Restoration Period. Unless either Landlord or Tenant so elects to
terminate this Lease, Landlord shall, subject to receipt of sufficient insurance proceeds (with any deductible to be treated as a current Operating Expense), promptly restore the Premises (excluding the improvements installed by Tenant or by
Landlord and paid for by Tenant), subject to delays arising from the collection of insurance proceeds, from Force Majeure events or as needed to obtain any license, clearance or other authorization of any kind required to enter into and restore the
Premises issued by any Governmental Authority having jurisdiction over the use, storage, handling, treatment, generation, release, disposal, removal or remediation of Hazardous Materials (as defined in Section 30) in, on or
about the Premises (collectively referred to herein as “Hazardous Materials Clearances”); provided, however, that if repair or restoration of the Premises is not substantially complete as of the end of the Maximum
Restoration Period or, if longer, the Restoration Period, Landlord may, in its sole and absolute discretion, elect not to proceed with such repair and 

  
 

 

			
	Net Laboratory	  	1165 Eastlake/Adaptive - Page 
14

  

 
restoration, or Tenant may by written notice to Landlord delivered within 10 business days of the expiration of the Maximum Restoration Period or, if longer, the Restoration Period, elect to
terminate this Lease, in which event Landlord shall be relieved of its obligation to make such repairs or restoration and this Lease shall terminate as of the date that is 75 days after the later of: (i) discovery of such damage or destruction,
or (ii) the date all required Hazardous Materials Clearances are obtained, but Landlord shall retain any Rent paid and the right to any Rent payable by Tenant prior to such election by Landlord or Tenant. 

Tenant, at its expense, shall promptly perform, subject to delays arising from the collection of insurance proceeds, from Force Majeure (as
defined in Section 34) events or to obtain Hazardous Material Clearances, all repairs or restoration not required to be done by Landlord and shall promptly re-enter the Premises and,
to the degree reasonably practicable based on the damage present, commence doing business in accordance with this Lease. Notwithstanding the foregoing, either Landlord or Tenant may terminate this Lease upon written notice to the other if the
Premises are damaged during the last year of the Term and Landlord reasonably estimates that it will take more than 2 months to repair such damage; provided, however, that such notice is delivered within 10 business days after the date that Landlord
provides Tenant with written notice of the estimated Restoration Period. Notwithstanding anything to the contrary contained herein, Landlord shall also have the right to terminate this Lease if insurance proceeds are not available for such
restoration. Rent shall be abated from the date all required Hazardous Material Clearances are obtained until the Premises are repaired and restored, in the proportion which the area of the Premises, if any, which is not usable by Tenant bears to
the total area of the Premises, unless Landlord provides Tenant with other space during the period of repair that is suitable for the temporary conduct of Tenant’s business. In the event that no Hazardous Material Clearances are required to be
obtained by Tenant with respect to the Premises, rent abatement shall commence on the date of discovery of the damage or destruction. Such abatement shall be the sole remedy of Tenant, and except as provided in this
Section 18, Tenant waives any right to terminate the Lease by reason of damage or casualty loss. 
 The provisions
of this Lease, including this Section 18, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises, or any other portion of the
Project, and any statute or regulation which is now or may hereafter be in effect shall have no application to this Lease or any damage or destruction to all or any part of the Premises or any other portion of the Project, the parties hereto
expressly agreeing that this Section 18 sets forth their entire understanding and agreement with respect to such matters. 

19. Condemnation. If the whole or any material part of the Premises or the Project is taken for any public or quasi-public use under
governmental law, ordinance, or regulation, or by right of eminent domain, or by private purchase in lieu thereof (a “Taking” or “Taken”), and the Taking would in Landlord’s reasonable judgment, either prevent
or materially interfere with Tenant’s use of the Premises or materially interfere with or impair Landlord’s ownership or operation of the Project, then upon written notice by Landlord this Lease shall terminate and Rent shall be
apportioned as of said date. If part of the Premises shall be Taken, and this Lease is not terminated as provided above, Landlord shall promptly restore the Premises and the Project as nearly as is commercially reasonable under the circumstances to
their condition prior to such partial Taking and the rentable square footage of the Building, the rentable square footage of the Premises, Tenant’s Share of Operating Expenses and the Rent payable hereunder during the unexpired Term shall be
reduced to such extent as may be fair and reasonable under the circumstances. Upon any such Taking, Landlord shall be entitled to receive the entire price or award from any such Taking without any payment to Tenant, and Tenant hereby assigns to
Landlord Tenant’s interest, if any, in such award. Tenant shall have the right, to the extent that same shall not diminish Landlord’s award, to make a separate claim against the condemning authority (but not Landlord) for such compensation
as may be separately awarded or recoverable by Tenant for moving expenses and damage to Tenant’s trade fixtures, if a separate award for such items is made to Tenant. Tenant hereby waives any and all rights it might otherwise have pursuant to
any provision of state law to terminate this Lease upon a partial Taking of the Premises or the Project.

 20. Events of Default. Each of the following events shall be a default
(“Default”) by Tenant under this Lease: 
 (a) Payment Defaults. Tenant shall fail to pay any installment of Rent or
any other payment hereunder when due; provided, however, that Landlord will give Tenant notice and an opportunity to cure any failure to pay Rent within 3 days of any such notice not more than once in any 12 month period. 

(b) Insurance. Any insurance required to be maintained by Tenant pursuant to this Lease shall be canceled or terminated or shall expire
or shall be reduced or materially changed, or Landlord shall receive a notice of nonrenewal of any such insurance and Tenant shall fail to obtain replacement insurance before the expiration of the current coverage. 

(c) Abandonment. Tenant shall abandon the Premises. 

(d) Improper Transfer. Tenant shall assign, sublease or otherwise transfer or attempt to transfer all or any portion of Tenant’s
interest in this Lease or the Premises except as expressly permitted herein, or Tenant’s interest in this Lease shall be attached, executed upon, or otherwise judicially seized and such action is not released within 90 days of the action. 

(e) Liens. Tenant shall fail to discharge or otherwise obtain the release of any lien placed upon the Premises in violation of this
Lease within 10 days after any such lien is filed against the Premises. 
 (f) Insolvency Events. Tenant or any guarantor or surety of
Tenant’s obligations hereunder shall: (A) make a general assignment for the benefit of creditors; (B) commence any case, proceeding or other action seeking to have an order for relief entered on its behalf as a debtor or to adjudicate
it a bankrupt or insolvent, or seeking reorganization, arrangement, adjustment, liquidation, dissolution or composition of it or its debts or seeking appointment of a receiver, trustee, custodian or other similar official for it or for all or of any
substantial part of its property (collectively a “Proceeding for Relief”); (C) become the subject of any Proceeding for Relief which is not dismissed within 90 days of its filing or entry; or (D) die or suffer a legal
disability (if Tenant, guarantor, or surety is an individual) or be dissolved or otherwise fail to maintain its legal existence (if Tenant, guarantor or surety is a corporation, partnership or other entity). 

(g) Estoppel Certificate or Subordination Agreement. Tenant fails to execute any document required from Tenant under Sections 23
or 27 within 5 days after a second notice requesting such document. 
 (h) Other Defaults. Tenant shall fail to comply with any
provision of this Lease other than those specifically referred to in this Section 20, and, except as otherwise expressly provided herein, such failure shall continue for a period of 30 days after written notice thereof from
Landlord to Tenant. 
 Any notice given under Section 20(h) hereof shall: (i) specify the alleged default, (ii) demand
that Tenant cure such default, (iii) be in lieu of, and not in addition to, or shall be deemed to be, any notice required under any provision of applicable law, and (iv) not be deemed a forfeiture or a termination of this Lease unless
Landlord elects otherwise in such notice; provided that if the nature of Tenant’s default pursuant to Section 20(h) is such that it cannot be cured by the payment of money and reasonably requires more than 30
days to cure, then Tenant shall not be deemed to be in default if Tenant commences such cure within said 30 day period and thereafter diligently prosecutes the same to completion; provided, however, that such cure shall be completed no
later than 90 days from the date of Landlord’s notice.

 21. Landlord’s Remedies. 

(a) Payment By Landlord; Interest. Upon a Default by Tenant hereunder, Landlord may, without waiving or releasing any obligation of
Tenant hereunder, make such payment or perform such act. All sums so paid or incurred by Landlord, together with interest thereon, from the date such sums were paid or incurred, at the annual rate equal to 12% per annum or the highest rate permitted
by law (the “Default Rate”), whichever is less, shall be payable to Landlord on demand as Additional Rent. Nothing herein shall be construed to create or impose a duty on Landlord to mitigate any damages resulting from Tenant’s
Default hereunder. 
 (b) Late Payment Rent. Late payment by Tenant to Landlord of Rent and other sums due will cause Landlord to
incur costs not contemplated by this Lease, the exact amount of which will be extremely difficult and impracticable to ascertain. Such costs include, but are not limited to, processing and accounting charges and late charges which may be imposed on
Landlord under any Mortgage covering the Premises. Therefore, if any installment of Rent due from Tenant is not received by Landlord within 5 days after the date such payment is due, Tenant shall pay to Landlord an additional sum equal to 6% of the
overdue Rent as a late charge. Notwithstanding the foregoing, before assessing a late charge the first time in any calendar year, Landlord shall provide Tenant written notice of the delinquency and will waive the right if Tenant pays such
delinquency within 5 days thereafter. The parties agree that this late charge represents a fair and reasonable estimate of the costs Landlord will incur by reason of late payment by Tenant. In addition to the late charge, Rent not paid when due
shall bear interest at the Default Rate from the 5th day after the date due until paid. 
 (c) Remedies. Upon the occurrence of a
Default, Landlord, at its option, without further notice or demand to Tenant, shall have in addition to all other rights and remedies provided in this Lease, at law or in equity, the option to pursue any one or more of the following remedies, each
and all of which shall be cumulative and nonexclusive, without any notice or demand whatsoever. 
 (i) Terminate this Lease,
or at Landlord’s option, Tenant’s right to possession only, in which event Tenant shall immediately surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which it may have for
possession or arrearages in rent, enter upon and take possession of the Premises and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without being liable for prosecution or any claim for damages
therefor; 
 (ii) Upon any termination of this Lease, whether pursuant to the foregoing
Section 21(c)(i) or otherwise, Landlord may recover from Tenant the following: 
 (A) The worth at
the time of award of any unpaid rent which has been earned at the time of such termination; plus 
 (B) The worth at the time
of award of the amount by which the unpaid rent which would have been earned after termination until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus 

(C) 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 rental loss that Tenant proves could have been reasonably avoided; plus 
 (D) Any other amount
necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result therefrom, specifically including, but
not limited to, brokerage commissions and advertising expenses incurred, expenses of remodeling the Premises or any portion thereof for a new tenant, whether for the same or a different use, and any special concessions made to obtain a new tenant;
and 
 (E) At Landlord’s election, such other amounts in addition to or in lieu of the foregoing as may be permitted
from time to time by applicable law.

 The term “rent” as used in this Section 21 shall be deemed to be
and to mean all sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or to others. As used in Sections 21(c)(ii)(A) and (B), above, the “worth at the time of
award” shall be computed by allowing interest at the Default Rate. As used in Section 21(c)(ii)(C) above, the “worth at the time of award” shall be computed by discounting such amount at the
discount rate of the Federal Reserve Bank of San Francisco at the time of award plus 1%. 
 (iii) Landlord may continue this
Lease in effect after Tenant’s Default and recover rent as it becomes due (Landlord and Tenant hereby agreeing that Tenant has the right to sublet or assign hereunder, subject only to reasonable limitations). Accordingly, if Landlord does not
elect to terminate this Lease following a Default by Tenant, Landlord may, from time to time, without terminating this Lease, enforce all of its rights and remedies hereunder, including the right to recover all Rent as it becomes due. 

(iv) Whether or not Landlord elects to terminate this Lease following a Default by Tenant, Landlord shall have the right to
terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises or may, in Landlord’s sole discretion, succeed to Tenant’s interest in such subleases,
licenses, concessions or arrangements. Upon Landlord’s election to succeed to Tenant’s interest in any such subleases, licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no
further right to or interest in the rent or other consideration receivable thereunder. 
 (v) Independent of the exercise of
any other remedy of Landlord hereunder or under applicable law, Landlord may conduct an environmental test of the Premises as generally described in Section 30(d) hereof, at Tenant’s expense. 

(d) Effect of Exercise. Exercise by Landlord of any remedies hereunder or otherwise available shall not be deemed to be an acceptance of
surrender of the Premises and/or a termination of this Lease by Landlord, it being understood that such surrender and/or termination can be effected only by the express written agreement of Landlord and Tenant. Any law, usage, or custom to the
contrary notwithstanding, Landlord shall have the right at all times to enforce the provisions of this Lease in strict accordance with the terms hereof; and the failure of Landlord at any time to enforce its rights under this Lease strictly in
accordance with same shall not be construed as having created a custom in any way or manner contrary to the specific terms, provisions, and covenants of this Lease or as having modified the same and shall not be deemed a waiver of Landlord’s
right to enforce one or more of its rights in connection with any subsequent default. A receipt by Landlord of Rent or other payment with knowledge of the breach of any covenant hereof shall not be deemed a waiver of such breach, and no waiver by
Landlord of any provision of this Lease shall be deemed to have been made unless expressed in writing and signed by Landlord. To the greatest extent permitted by law, Tenant waives the service of notice of Landlord’s intention to re-enter, re-take or otherwise obtain possession of the Premises as provided in any statute, or to institute legal proceedings to that end, and also waives all right of
redemption in case Tenant shall be dispossessed by a judgment or by warrant of any court or judge. Any reletting of the Premises or any portion thereof shall be on such terms and conditions as Landlord in its sole discretion may determine. Landlord
shall not be liable for, nor shall Tenant’s obligations hereunder be diminished because of, Landlord’s failure to relet the Premises or collect rent due in respect of such reletting or otherwise to mitigate any damages arising by reason of
Tenant’s Default. 
 22. Assignment and Subletting. 

(a) General Prohibition. Without Landlord’s prior written consent subject to and on the conditions described in this
Section 22, Tenant shall not, directly or indirectly, voluntarily or by operation of law, assign this Lease or sublease the Premises or any part thereof or mortgage, pledge, or hypothecate its leasehold interest or grant
any concession or license within the Premises, and any attempt to do any of the foregoing shall be void and of no effect. If Tenant is a corporation, partnership or 

  
 

 

			
	Net Laboratory	  	1165 Eastlake/Adaptive - Page 
18

  

 
limited liability company, the shares or other ownership interests thereof which are not actively traded upon a stock exchange or in the over-the-counter market, a transfer or series of transfers whereby 50% or more of the issued and outstanding shares or other ownership interests of such corporation are, or voting control is, transferred (but
excepting transfers upon deaths of individual owners) from a person or persons or entity or entities which were owners thereof at time of execution of this Lease to persons or entities who were not owners of shares or other ownership interests of
the corporation, partnership or limited liability company at time of execution of this Lease, shall be deemed an assignment of this Lease requiring the consent of Landlord as provided in this Section 22. 

(b) Permitted Transfers. If Tenant desires to assign, sublease, hypothecate or otherwise transfer this Lease or sublet the Premises
other than pursuant to a Permitted Assignment (as defined below), then at least 15 business days, but not more than 60 business days, before the date Tenant desires the assignment or sublease to be effective (the “Assignment Date”),
Tenant shall give Landlord a notice (the “Assignment Notice”) containing such information about the proposed assignee or sublessee, including the proposed use of the Premises and any Hazardous Materials proposed to be used, stored
handled, treated, generated in or released or disposed of from the Premises, the Assignment Date, any relationship between Tenant and the proposed assignee or sublessee, and all material terms and conditions of the proposed assignment or sublease,
including a copy of any proposed assignment or sublease in its final form, and such other information as Landlord may deem reasonably necessary or appropriate to its consideration whether to grant its consent. Landlord may, by giving written notice
to Tenant within 15 business days after receipt of the Assignment Notice: (i) grant such consent (provided that Landlord shall, in its reasonable discretion, further have the right to review and approve or disapprove the proposed form of
sublease prior to the effective date of any such subletting), (ii) refuse such consent, in its reasonable discretion; or (iii) with respect to any assignment of this Lease or sublease or series of subleases that would result in more than 50% of
the Premises being subleased for substantially the remainder of the Term, terminate this Lease with respect to the space described in the Assignment Notice as of the Assignment Date (an “Assignment Termination”). Among other
reasons, it shall be reasonable for Landlord to withhold its consent in any of these instances: (1) the proposed assignee or subtenant is a governmental agency; (2) in Landlord’s reasonable judgment, the use of the Premises by the
proposed assignee or subtenant would entail any alterations that would lessen the value of the leasehold improvements in the Premises, or would require increased services by Landlord; (3) in Landlord’s good faith reasonable judgment, the
proposed assignee or subtenant is engaged in areas of scientific research or other business concerns that are controversial such that they may (i) attract or cause negative publicity for or about the Building or the Project,
(ii) negatively affect the reputation of the Building, the Project or Landlord, (iii) attract protestors to the Building or the Project, or (iv) lessen the attractiveness of the Building or the Project to any tenants or prospective
tenants, purchasers or lenders; (4) in Landlord’s reasonable judgment, the proposed assignee or subtenant lacks the creditworthiness to support the financial obligations it will incur under the proposed assignment or sublease;
(5) Landlord has received from any prior landlord to the proposed assignee or subtenant a negative report concerning such prior landlord’s experience with the proposed assignee or subtenant; (6) Landlord has experienced previous
defaults by or is in litigation with the proposed assignee or subtenant; (7) the use of the Premises by the proposed assignee or subtenant will violate any applicable Legal Requirement; or (8) the assignment or sublease is prohibited by
Landlord’s lender. If Landlord delivers notice of its election to exercise an Assignment Termination, Tenant shall have the right to withdraw such Assignment Notice by written notice to Landlord of such election within 5 business days after
Landlord’s notice electing to exercise the Assignment Termination. If Tenant withdraws such Assignment Notice, this Lease shall continue in full force and effect. If Tenant does not withdraw such Assignment Notice, this Lease, and the term and
estate herein granted, shall terminate as of the Assignment Date with respect to the space described in such Assignment Notice. No failure of Landlord to exercise any such option to terminate this Lease, or to deliver a timely notice in response to
the Assignment Notice, shall be deemed to be Landlord’s consent to the proposed assignment, sublease or other transfer. Tenant shall pay to Landlord a fee equal to Two Thousand Five Hundred Dollars ($2,500) in connection with its consideration
of any Assignment Notice and/or its preparation or review of any consent documents. Notwithstanding the foregoing, Landlord’s consent to an assignment of this Lease or a subletting of any portion of the Premises to any entity controlling,
controlled by or under common control with Tenant (a “Control Permitted Assignment”) shall not be required, provided that Landlord shall have the right to 

  
 

 

			
	Net Laboratory	  	1165 Eastlake/Adaptive - Page 
19

  

 
approve the form of any such sublease or assignment. In addition, Tenant shall have the right to assign this Lease, upon 30 days prior written notice to Landlord but without obtaining
Landlord’s prior written consent, to a corporation or other entity which is a successor-in-interest to Tenant, by way of merger, consolidation or corporate
reorganization, or by the purchase of all or substantially all of the assets or the ownership interests of Tenant provided that (i) such merger or consolidation, or such acquisition or assumption, as the case may be, is for a good business
purpose and not principally for the purpose of transferring the Lease, and (ii) the net worth (as determined in accordance with generally accepted accounting principles (“GAAP”)) of the assignee is not less than the greater of
the net worth (as determined in accordance with GAAP) of Tenant as of (A) the Commencement Date, or (B) as of the date of Tenant’s most current quarterly or annual financial statements, and (iii) such assignee shall agree in
writing to assume all of the terms, covenants and conditions of this Lease (a “Corporate Permitted Assignment”). Control Permitted Assignments and Corporate Permitted Assignments are hereinafter referred to as “Permitted
Assignments.” 
 (c) Additional Conditions. As a condition to any such assignment or subletting, whether or not
Landlord’s consent is required, Landlord may require: 
 (i) that any assignee or subtenant agree, in writing at the
time of such assignment or subletting, that if Landlord gives such party notice that Tenant is in default under this Lease, such party shall thereafter make all payments otherwise due Tenant directly to Landlord, which payments will be received by
Landlord without any liability except to credit such payment against those due under the Lease, and any such third party shall agree to attorn to Landlord or its successors and assigns should this Lease be terminated for any reason; provided,
however, in no event shall Landlord or its successors or assigns be obligated to accept such attornment; and 
 (ii) A
list of Hazardous Materials, certified by the proposed assignee or sublessee to be true and correct, which the proposed assignee or sublessee intends to use, store, handle, treat, generate in or release or dispose of from the Premises, together with
copies of all documents relating to such use, storage, handling, treatment, generation, release or disposal of Hazardous Materials by the proposed assignee or subtenant in the Premises or on the Project, prior to the proposed assignment or
subletting, including, without limitation: permits; approvals; reports and correspondence; storage and management plans; plans relating to the installation of any storage tanks to be installed in or under the Project (provided, said installation of
tanks shall only be permitted after Landlord has given its written consent to do so, which consent may be withheld in Landlord’s sole and absolute discretion); and all closure plans or any other documents required by any and all federal, state
and local Governmental Authorities for any storage tanks installed in, on or under the Project for the closure of any such tanks. Neither Tenant nor any such proposed assignee or subtenant is required, however, to provide Landlord with any
portion(s) of the such documents containing information of a proprietary nature which, in and of themselves, do not contain a reference to any Hazardous Materials or hazardous activities. 

(d) No Release of Tenant, Sharing of Excess Rents. Notwithstanding any assignment or subletting, Tenant and any guarantor or surety of
Tenant’s obligations under this Lease shall at all times remain fully and primarily responsible and liable for the payment of Rent and for compliance with all of Tenant’s other obligations under this Lease. If the Rent due and payable by a
sublessee or assignee (or a combination of the rental payable under such sublease or assignment plus any bonus or other consideration therefor or incident thereto in any form) exceeds the sum of the rental payable under this Lease, (excluding
however, any Rent payable under this Section) and actual and reasonable brokerage fees, legal costs and any design or construction fees directly related to and required pursuant to the terms of any such sublease) (“Excess Rent”),
then Tenant shall be bound and obligated to pay Landlord as Additional Rent hereunder 50% of such Excess Rent within 10 days following receipt thereof by Tenant. If Tenant shall sublet the Premises or any part thereof, Tenant hereby immediately and
irrevocably assigns to Landlord, as security for Tenant’s obligations under this Lease, all rent from any such subletting, and Landlord as assignee and as
attorney-in-fact for Tenant, or a receiver for Tenant appointed on Landlord’s application, may collect such rent and apply it toward Tenant’s obligations under
this Lease; except that, until the occurrence of a Default, Tenant shall have the right to collect such rent.

 (e) No Waiver. The consent by Landlord to an assignment or subletting shall not
relieve Tenant or any assignees of this Lease or any sublessees of the Premises from obtaining the consent of Landlord to any further assignment or subletting nor shall it release Tenant or any assignee or sublessee of Tenant from full and primary
liability under the Lease. The acceptance of Rent hereunder, or the acceptance of performance of any other term, covenant, or condition thereof, from any other person or entity shall not be deemed to be a waiver of any of the provisions of this
Lease or a consent to any subletting, assignment or other transfer of the Premises. 
 (f) Prior Conduct of Proposed Transferee.
Notwithstanding any other provision of this Section 22, if (i) the proposed assignee or sublessee of Tenant has been required by any prior landlord, lender or Governmental Authority to take remedial action in
connection with Hazardous Materials contaminating a property, where the contamination resulted from such party’s action or use of the property in question, (ii) the proposed assignee or sublessee is subject to an enforcement order issued
by any Governmental Authority in connection with the use, storage, handling, treatment, generation, release or disposal of Hazardous Materials (including, without limitation, any order related to the failure to make a required reporting to any
Governmental Authority), or (iii) because of the existence of a pre-existing environmental condition in the vicinity of or underlying the Project, the risk that Landlord would be targeted as a responsible
party in connection with the remediation of such pre-existing environmental condition would be materially increased or exacerbated by the proposed use of Hazardous Materials by such proposed assignee or
sublessee, Landlord shall have the absolute right to refuse to consent to any assignment or subletting to any such party.  
 23.
Estoppel Certificate. Tenant shall, within 10 business days of written notice from Landlord, execute, acknowledge and deliver a statement in writing in any form reasonably requested by a proposed lender or purchaser, (i) certifying that
this Lease is unmodified and in full force and effect (or, if modified, stating the nature of such modification and certifying that this Lease as so modified is in full force and effect) and the dates to which the rental and other charges are paid
in advance, if any, (ii) acknowledging that there are not any uncured defaults on the part of Landlord hereunder, or specifying such defaults if any are claimed, and (iii) setting forth such further information with respect to the status
of this Lease or the Premises as may be requested thereon. Any such statement may be relied upon by any prospective purchaser or encumbrancer of all or any portion of the real property of which the Premises are a part. Tenant’s failure to
deliver such statement within such time shall, at the option of Landlord, constitute a Default under this Lease, and, in any event, shall be conclusive upon Tenant that the Lease is in full force and effect and without modification except as may be
represented by Landlord in any certificate prepared by Landlord and delivered to Tenant for execution. 
 24. Quiet Enjoyment. So long
as Tenant is not in Default under this Lease, Tenant shall, subject to the terms of this Lease, at all times during the Term, have peaceful and quiet enjoyment of the Premises against any person claiming by, through or under Landlord. 

25. Prorations. All prorations required or permitted to be made hereunder shall be made on the basis of a 360 day year and 30 day
months. 
 26. Rules and Regulations. Tenant shall, at all times during the Term and any extension thereof, comply with all reasonable
rules and regulations at any time or from time to time established by Landlord covering use of the Premises and the Project. The current rules and regulations are attached hereto as Exhibit E. If there is any conflict between said rules and
regulations and other provisions of this Lease, the terms and provisions of this Lease shall control. Landlord shall not have any liability or obligation for the breach of any rules or regulations by other tenants in the Project and shall not
enforce such rules and regulations in a discriminatory manner. 
 27. Subordination. This Lease and Tenant’s interest and rights
hereunder are hereby made and shall be subject and subordinate at all times to the lien of any Mortgage now existing or hereafter created on or against the Project or the Premises, and all amendments, restatements, renewals, modifications,
consolidations, refinancing, assignments and extensions thereof, without the necessity of 

  
 

 

			
	Net Laboratory	  	1165 Eastlake/Adaptive - Page 
21

  

 
any further instrument or act on the part of Tenant; provided, however that so long as there is no Default hereunder, Tenant’s right to possession of the Premises shall not be
disturbed by the Holder of any such Mortgage. Tenant agrees, at the election of the Holder of any such Mortgage, to attorn to any such Holder. Tenant agrees upon demand to execute, acknowledge and deliver such instruments, confirming such
subordination, and such instruments of attornment as shall be requested by any such Holder, provided any such instruments contain appropriate non-disturbance provisions assuring Tenant’s quiet enjoyment
of the Premises as set forth in Section 24 hereof. Notwithstanding the foregoing, any such Holder may at any time subordinate its Mortgage to this Lease, without Tenant’s consent, by notice in writing to Tenant, and
thereupon this Lease shall be deemed prior to such Mortgage without regard to their respective dates of execution, delivery or recording and in that event such Holder shall have the same rights with respect to this Lease as though this Lease had
been executed prior to the execution, delivery and recording of such Mortgage and had been assigned to such Holder. The term “Mortgage” whenever used in this Lease shall be deemed to include deeds of trust, security assignments and
any other encumbrances, and any reference to the “Holder” of a Mortgage shall be deemed to include the beneficiary under a deed of trust. As of the date of this Lease, there is no existing Mortgage encumbering the Project. 

28. Surrender. Upon the expiration of the Term or earlier termination of Tenant’s right of possession, Tenant shall surrender the
Premises to Landlord in the same condition as received, subject to any Alterations or Installations permitted by Landlord to remain in the Premises, free of Hazardous Materials brought upon, kept, used, stored, handled, treated, generated in, or
released or disposed of from, the Premises by any person other than a Landlord Party (collectively, “Tenant HazMat Operations”) and released of all Hazardous Materials Clearances, broom clean, ordinary wear and tear and casualty
loss and condemnation covered by Sections 18 and 19 excepted. At least 3 months prior to the surrender of the Premises or such earlier date as Tenant may elect to cease operations at the Premises, Tenant shall
deliver to Landlord a narrative description of the actions proposed (or required by any Governmental Authority) to be taken by Tenant in order to surrender the Premises (including any Installations permitted by Landlord to remain in the Premises) at
the expiration or earlier termination of the Term, free from any residual impact from the Tenant HazMat Operations and otherwise released for unrestricted use and occupancy (the “Decommissioning and HazMat Closure Plan”).
Such Decommissioning and HazMat Closure Plan shall be accompanied by a current listing of (i) all Hazardous Materials licenses and permits held by or on behalf of any Tenant Party with respect to the Premises, and (ii) all Hazardous
Materials used, stored, handled, treated, generated, released or disposed of from the Premises, and shall be subject to the review and approval of Landlord’s environmental consultant. In connection with the review and approval of the
Decommissioning and HazMat Closure Plan, upon the request of Landlord, Tenant shall deliver to Landlord or its consultant such additional non-proprietary information concerning Tenant HazMat Operations as
Landlord shall request. On or before such surrender, Tenant shall deliver to Landlord evidence that the approved Decommissioning and HazMat Closure Plan shall have been satisfactorily completed and Landlord shall have the right, subject to
reimbursement at Tenant’s expense as set forth below, to cause Landlord’s environmental consultant to inspect the Premises and perform such additional procedures as may be deemed reasonably necessary to confirm that the Premises are, as of
the effective date of such surrender or early termination of the Lease, free from any residual impact from Tenant HazMat Operations. Tenant shall reimburse Landlord, as Additional Rent, for the actual out-of-pocket expense incurred by Landlord for Landlord’s environmental consultant to review and approve the Decommissioning and HazMat Closure Plan and to visit the Premises and verify satisfactory
completion of the same, which cost shall not exceed $5,000. Landlord shall have the unrestricted right to deliver such Decommissioning and HazMat Closure Plan and any report by Landlord’s environmental consultant with respect to the surrender
of the Premises to third parties. 
 If Tenant shall fail to prepare or submit a Decommissioning and HazMat Closure Plan approved by
Landlord, or if Tenant shall fail to complete the approved Decommissioning and HazMat Closure Plan, or if such Decommissioning and HazMat Closure Plan, whether or not approved by Landlord, shall fail to adequately address any residual effect of
Tenant HazMat Operations in, on or about the Premises, Landlord shall have the right to take such actions as Landlord may deem reasonable or appropriate to assure that the Premises and the Project are surrendered free from any residual impact from
Tenant HazMat Operations, the cost of which actions shall be reimbursed by Tenant as Additional Rent, without regard to the limitation set forth in the first paragraph of this Section 28.

 Tenant shall immediately return to Landlord all keys and/or access cards to parking, the
Project, restrooms or all or any portion of the Premises furnished to or otherwise procured by Tenant. If any such access card or key is lost, Tenant shall pay to Landlord, at Landlord’s election, either the cost of replacing such lost access
card or key or the cost of reprogramming the access security system in which such access card was used or changing the lock or locks opened by such lost key. Any Tenant’s Property, Alterations and property not so removed by Tenant as permitted
or required herein shall be deemed abandoned and may be stored, removed, and disposed of by Landlord at Tenant’s expense, and Tenant waives all claims against Landlord for any damages resulting from Landlord’s retention and/or disposition
of such property. All obligations of Tenant hereunder not fully performed as of the termination of the Term, including the obligations of Tenant under Section 30 hereof, shall survive the expiration or earlier termination
of the Term, including, without limitation, indemnity obligations, payment obligations with respect to Rent and obligations concerning the condition and repair of the Premises. 

29. Waiver of Jury Trial. TO THE EXTENT PERMITTED BY LAW, TENANT AND LANDLORD WAIVE ANY RIGHT TO TRIAL BY JURY OR TO HAVE A JURY
PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT, OR OTHERWISE, BETWEEN LANDLORD AND TENANT ARISING OUT OF THIS LEASE OR ANY OTHER INSTRUMENT, DOCUMENT, OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR THE
TRANSACTIONS RELATED HERETO. 
 30. Environmental Requirements. 

(a) Prohibition/Compliance/Indemnity. Tenant shall not cause or permit any Hazardous Materials (as hereinafter defined) to be brought
upon, kept, used, stored, handled, treated, generated in or about, or released or disposed of from, the Premises or the Project in violation of applicable Environmental Requirements (as hereinafter defined) by Tenant or any Tenant Party. If Tenant
breaches the obligation stated in the preceding sentence, or if the presence of Hazardous Materials in the Premises during the Term or any holding over results in contamination of the Premises, the Project or any adjacent property or if
contamination of the Premises, the Project or any adjacent property by Hazardous Materials brought into, kept, used, stored, handled, treated, generated in or about, or released or disposed of from, the Premises by anyone other than Landlord and
Landlord’s employees, agents and contractors otherwise occurs during the Term or any holding over, Tenant hereby indemnifies and shall defend and hold Landlord, its officers, directors, employees, agents and contractors harmless from any and
all actions (including, without limitation, remedial or enforcement actions of any kind, administrative or judicial proceedings, and orders or judgments arising out of or resulting therefrom), costs, claims, damages (including, without limitation,
punitive damages and damages based upon diminution in value of the Premises or the Project, or the loss of, or restriction on, use of the Premises or any portion of the Project), expenses (including, without limitation, attorneys’,
consultants’ and experts’ fees, court costs and amounts paid in settlement of any claims or actions), fines, forfeitures or other civil, administrative or criminal penalties, injunctive or other relief (whether or not based upon personal
injury, property damage, or contamination of, or adverse effects upon, the environment, water tables or natural resources), liabilities or losses (collectively, “Environmental Claims”) which arise during or after the Term as a
result of such contamination. This indemnification of Landlord by Tenant includes, without limitation, costs incurred in connection with any investigation of site conditions or any cleanup, treatment, remedial, removal, or restoration work required
by any federal, state or local Governmental Authority because of Hazardous Materials present in the air, soil or ground water above, on, or under the Premises. Without limiting the foregoing, if the presence of any Hazardous Materials on the
Premises, the Project or any adjacent property caused or permitted by Tenant or any Tenant Party results in any contamination of the Premises, the Project or any adjacent property, Tenant shall promptly take all actions at its sole expense and in
accordance with applicable Environmental Requirements as are necessary to return the Premises, the Project or any adjacent property to the condition existing prior to the time of such contamination, provided that Landlord’s approval of such
action shall first be obtained, which approval shall not unreasonably be withheld so long as such actions would not potentially have any material adverse long-

  
 

 

			
	Net Laboratory	  	1165 Eastlake/Adaptive - Page 
23

  

 
term or short-term effect on the Premises or the Project. Notwithstanding anything to the contrary contained in this Section 30, Tenant shall not be responsible for, and the indemnification
and hold harmless obligation set forth in this paragraph shall not apply to (i) contamination in the Premises which Tenant can prove to Landlord’s reasonable satisfaction existed in the Premises immediately prior to the Commencement Date,
or (ii) the presence of any Hazardous Materials in the Premises which Tenant can prove to Landlord’s reasonable satisfaction migrated from outside of the Premises into the Premises, unless in either case, the presence of such Hazardous
Materials (x) is the result of a breach by Tenant of any of its obligations under this Lease, or (y) was caused, contributed to or exacerbated by Tenant or any Tenant Party. 

(b) Business. Landlord acknowledges that it is not the intent of this Section 30 to prohibit Tenant from using
the Premises for the Permitted Use. Tenant may operate its business according to prudent industry practices so long as the use or presence of Hazardous Materials is strictly and properly monitored according to all then applicable Environmental
Requirements. As a material inducement to Landlord to allow Tenant to use Hazardous Materials in connection with its business, Tenant agrees to deliver to Landlord prior to the Commencement Date a list identifying each type of Hazardous Materials to
be brought upon, kept, used, stored, handled, treated, generated on, or released or disposed of from, the Premises and setting forth any and all governmental approvals or permits required in connection with the presence, use, storage, handling,
treatment, generation, release or disposal of such Hazardous Materials on or from the Premises (“Hazardous Materials List”). Upon Landlord’s request, or any time that Tenant is required to deliver a Hazardous Materials List to
any Governmental Authority (e.g., the fire department) in connection with Tenant’s use or occupancy of the Premises, Tenant shall deliver to Landlord a copy of such Hazardous Materials List. Tenant shall deliver to Landlord true and correct
copies of the following documents (the “Haz Mat Documents”) relating to the use, storage, handling, treatment, generation, release or disposal of Hazardous Materials prior to the Commencement Date, or if unavailable at that time,
concurrent with the receipt from or submission to a Governmental Authority: permits; approvals; reports and correspondence; storage and management plans, notice of violations of any Legal Requirements; plans relating to the installation of any
storage tanks to be installed in or under the Project (provided, said installation of tanks shall only be permitted after Landlord has given Tenant its written consent to do so, which consent may be withheld in Landlord’s sole and absolute
discretion); all closure plans or any other documents required by any and all federal, state and local Governmental Authorities for any storage tanks installed in, on or under the Project for the closure of any such tanks; and a Surrender Plan (to
the extent surrender in accordance with Section 28 cannot be accomplished in 3 months). Tenant is not required, however, to provide Landlord with any portion(s) of the Haz Mat Documents containing information of a
proprietary nature which, in and of themselves, do not contain a reference to any Hazardous Materials or hazardous activities. It is not the intent of this Section to provide Landlord with information which could be detrimental to Tenant’s
business should such information become possessed by Tenant’s competitors. 
 (c) Tenant Representation and Warranty. Tenant
hereby represents and warrants to Landlord that (i) neither Tenant nor any of its legal predecessors has been required by any prior landlord, lender or Governmental Authority at any time to take remedial action in connection with Hazardous
Materials contaminating a property which contamination was permitted by Tenant of such predecessor or resulted from Tenant’s or such predecessor’s action or use of the property in question, and (ii) Tenant is not subject to any
enforcement order issued by any Governmental Authority in connection with the use, storage, handling, treatment, generation, release or disposal of Hazardous Materials (including, without limitation, any order related to the failure to make a
required reporting to any Governmental Authority). If Landlord determines that this representation and warranty was not true as of the date of this lease, Landlord shall have the right to terminate this Lease in Landlord’s sole and absolute
discretion. 
 (d) Testing. Landlord shall have the right to conduct annual tests of the Premises to determine whether any
contamination of the Premises or the Project has occurred as a result of Tenant’s use. Tenant shall be required to pay the cost of such annual test of the Premises; provided, however, that if Tenant conducts its own tests of the Premises using
third party contractors and test procedures acceptable to Landlord which tests are certified to Landlord, Landlord shall accept such tests in lieu of the annual tests to be paid for by Tenant. In addition, at any time, and from time to time, prior
to the 

  
 

 

			
	Net Laboratory	  	1165 Eastlake/Adaptive - Page 
24

  

 
expiration or earlier termination of the Term, Landlord shall have the right to conduct appropriate tests of the Premises and the Project to determine if contamination has occurred as a result of
Tenant’s use of the Premises. In connection with such testing, upon the request of Landlord, Tenant shall deliver to Landlord or its consultant such non-proprietary information concerning the use of
Hazardous Materials in or about the Premises by Tenant or any Tenant Party. If contamination has occurred for which Tenant is liable under this Section 30, Tenant shall pay all costs to conduct such tests. If no such
contamination is found, Landlord shall pay the costs of such tests (which shall not constitute an Operating Expense). Landlord shall provide Tenant with a copy of all third party, non-confidential reports and
tests of the Premises made by or on behalf of Landlord during the Term without representation or warranty and subject to a confidentiality agreement. Tenant shall, at its sole cost and expense, promptly and satisfactorily remediate any environmental
conditions identified by such testing in accordance with all Environmental Requirements. Landlord’s receipt of or satisfaction with any environmental assessment in no way waives any rights which Landlord may have against Tenant. 

(e) Underground Tanks. Tenant shall have no right to use or install any underground or other storage tanks at the Project. 

(f) Tenant’s Obligations. Tenant’s obligations under this Section 30 shall survive the expiration or
earlier termination of the Lease. During any period of time after the expiration or earlier termination of this Lease required by Tenant or Landlord to complete the removal from the Premises of any Hazardous Materials (including, without limitation,
the release and termination of any licenses or permits restricting the use of the Premises and the completion of the approved Surrender Plan), Tenant shall continue to pay the full Rent in accordance with this Lease for any portion of the Premises
not relet by Landlord in Landlord’s sole discretion, which Rent shall be prorated daily. 
 (g) Definitions. As used herein, the
term “Environmental Requirements” means all applicable present and future statutes, regulations, ordinances, rules, codes, judgments, orders or other similar enactments of any Governmental Authority regulating or relating to health,
safety, or environmental conditions on, under, or about the Premises or the Project, or the environment, including without limitation, the following: the Comprehensive Environmental Response, Compensation and Liability Act; the Resource Conservation
and Recovery Act; and all state and local counterparts thereto, and any regulations or policies promulgated or issued thereunder. As used herein, the term “Hazardous Materials” means and includes any substance, material, waste,
pollutant, or contaminant listed or defined as hazardous or toxic, or regulated by reason of its impact or potential impact on humans, animals and/or the environment under any Environmental Requirements, asbestos and petroleum, including crude oil
or any fraction thereof, natural gas liquids, liquefied natural gas, or synthetic gas usable for fuel (or mixtures of natural gas and such synthetic gas). As defined in Environmental Requirements, Tenant is and shall be deemed to be the
“operator” of Tenant’s “facility” and the “owner” of all Hazardous Materials brought on the Premises by Tenant or any Tenant Party, and the wastes,
by-products, or residues generated, resulting, or produced therefrom. 
 31. Tenant’s
Remedies/Limitation of Liability. Landlord shall not be in default hereunder unless Landlord fails to perform any of its obligations hereunder within 30 days after written notice from Tenant specifying such failure (unless such performance will,
due to the nature of the obligation, require a period of time in excess of 30 days and Landlord commences such performance within such 30 day period and thereafter continues to diligently prosecute the same to completion, then after such period of
time as is reasonably necessary). Upon any default by Landlord, Tenant shall give notice by registered or certified mail to any Holder of a Mortgage covering the Premises and to any landlord of any lease of property in or on which the Premises are
located and Tenant shall offer such Holder and/or landlord a reasonable opportunity to cure the default, including time to obtain possession of the Project by power of sale or a judicial action if such should prove necessary to effect a cure;
provided Landlord shall have furnished to Tenant in writing the names and addresses of all such persons who are to receive such notices. All obligations of Landlord hereunder shall be construed as covenants, not conditions; and, except as may
be otherwise expressly provided in this Lease, Tenant may not terminate this Lease for breach of Landlord’s obligations hereunder.

 Notwithstanding the foregoing, if any claimed Landlord default hereunder will immediately,
materially and adversely affect Tenant’s ability to conduct its business in the Premises (a “Material Landlord Default”), Tenant shall, as soon as reasonably possible, give Landlord written notice of such claim which notice
shall specifically state that a Material Landlord Default exists and telephonic notice to Tenant’s principal contact with Landlord. Landlord shall then have 2 business days to commence cure of such claimed Material Landlord Default and shall
diligently prosecute such cure to completion. If such claimed Material Landlord Default is not a default by Landlord hereunder, Landlord shall be entitled to recover from Tenant, as Additional Rent, any costs incurred by Landlord in connection with
such cure in excess of the costs, if any, that Landlord would otherwise have been liable to pay hereunder. If Landlord fails to commence cure of any claimed Material Landlord Default as provided above, Tenant may commence and prosecute such cure to
completion provided that it does not adversely affect any Building Systems or the Building Structure, and shall be entitled to recover the costs of such cure (but not any consequential or other damages) from Landlord by way of reimbursement from
Landlord with no right to offset against Rent, to the extent of Landlord’s obligation to cure such claimed Material Landlord Default hereunder, subject to the limitations set forth in this Lease. 

All obligations of Landlord under this Lease will be binding upon Landlord only during the period of its ownership of the Premises and not thereafter. The
term “Landlord” in this Lease shall mean only the owner for the time being of the Premises. Upon the transfer by such owner of its interest in the Premises, such owner shall thereupon be released and discharged from all obligations
of Landlord thereafter accruing, but such obligations shall be binding during the Term upon each new owner for the duration of such owner’s ownership. 

32. Inspection and Access. Landlord and its agents, representatives, and contractors may enter the Premises at any reasonable time to
inspect the Premises and to make such repairs as may be required or permitted pursuant to this Lease and for any other business purpose. Landlord and Landlord’s representatives may enter the Premises during business hours on not less than 48
hours advance written notice (except in the case of emergencies in which case no such notice shall be required and such entry may be at any time) for the purpose of effecting any such repairs, inspecting the Premises, showing the Premises to
prospective purchasers and, during the last 18 months of the Term, to prospective tenants or for any other business purpose. Landlord may erect a suitable sign on the Premises stating the Premises are available to let or that the Project is
available for sale. Landlord may grant easements, make public dedications, create restrictions on or about the Project, provided that no such easement, dedication, designation or restriction materially, adversely affects Tenant’s use or
occupancy of the Premises for the Permitted Use. At Landlord’s request, Tenant shall execute such instruments as may be necessary for such easements, dedications or restrictions. Tenant shall at all times, except in the case of emergencies,
have the right to escort Landlord or its agents, representatives, contractors or guests while the same are in the Premises, provided such escort does not materially and adversely affect Landlord’s access rights hereunder. 

33. Security. Tenant acknowledges and agrees that security devices and services, if any, while intended to deter crime may not in given
instances prevent theft or other criminal acts and that Landlord is not providing any security services with respect to the Premises. Tenant agrees that Landlord shall not be liable to Tenant for, and Tenant waives any claim against Landlord with
respect to, any loss by theft or any other damage suffered or incurred by Tenant in connection with any unauthorized entry into the Premises or any other breach of security with respect to the Premises. Tenant shall be solely responsible for the
personal safety of Tenant’s officers, employees, agents, contractors, guests and invitees while any such person is in, on or about the Premises and/or the Project. Tenant shall at Tenant’s cost obtain insurance coverage to the extent
Tenant desires protection against such criminal acts. 
 34. Force Majeure. Except for the payment of Rent, neither Landlord nor
Tenant shall be held responsible or liable for delays in the performance of its obligations hereunder when caused by, related to, or arising out of acts of God, sinkholes or subsidence, strikes, lockouts, or other labor disputes, embargoes,
quarantines, weather, national, regional, or local disasters, calamities, or catastrophes, inability to obtain labor or materials (or reasonable substitutes therefor) at reasonable costs or failure of,

or inability to obtain, utilities necessary for performance, governmental restrictions, orders, limitations, regulations, or controls, national emergencies, delay in issuance or revocation of
permits, enemy or hostile governmental action, terrorism, insurrection, riots, civil disturbance or commotion, fire or other casualty, and other causes or events beyond their reasonable control (“Force Majeure”). 

35. Brokers. Landlord and Tenant each represents and warrants that it has not dealt with any broker, agent or other person
(collectively, “Broker”) in connection with this transaction and that no Broker brought about this transaction, other than Flinn Ferguson and Newmark Knight Frank. Landlord and Tenant each hereby agree to indemnify and hold the
other harmless from and against any claims by any Broker, other than the broker, if any named in this Section 35, claiming a commission or other form of compensation by virtue of having dealt with Tenant or Landlord, as
applicable, with regard to this leasing transaction. 
 36. Limitation on Landlord’s Liability. NOTWITHSTANDING ANYTHING SET
FORTH HEREIN OR IN ANY OTHER AGREEMENT BETWEEN LANDLORD AND TENANT TO THE CONTRARY: (A) LANDLORD SHALL NOT BE LIABLE TO TENANT OR ANY OTHER PERSON FOR (AND TENANT AND EACH SUCH OTHER PERSON ASSUME ALL RISK OF) LOSS, DAMAGE OR INJURY, WHETHER
ACTUAL OR CONSEQUENTIAL TO: TENANT’S PERSONAL PROPERTY OF EVERY KIND AND DESCRIPTION, INCLUDING, WITHOUT LIMITATION TRADE FIXTURES, EQUIPMENT, INVENTORY, SCIENTIFIC RESEARCH, SCIENTIFIC EXPERIMENTS, LABORATORY ANIMALS, PRODUCT, SPECIMENS,
SAMPLES, AND/OR SCIENTIFIC, BUSINESS, ACCOUNTING AND OTHER RECORDS OF EVERY KIND AND DESCRIPTION KEPT AT THE PREMISES AND ANY AND ALL INCOME DERIVED OR DERIVABLE THEREFROM; (B) THERE SHALL BE NO PERSONAL RECOURSE TO LANDLORD FOR ANY ACT OR
OCCURRENCE IN, ON OR ABOUT THE PREMISES OR ARISING IN ANY WAY UNDER THIS LEASE OR ANY OTHER AGREEMENT BETWEEN LANDLORD AND TENANT WITH RESPECT TO THE SUBJECT MATTER HEREOF AND ANY LIABILITY OF LANDLORD HEREUNDER SHALL BE STRICTLY LIMITED SOLELY TO
LANDLORD’S INTEREST IN THE PROJECT OR ANY PROCEEDS FROM SALE OR CONDEMNATION THEREOF AND ANY INSURANCE PROCEEDS PAYABLE IN RESPECT OF LANDLORD’S INTEREST IN THE PROJECT OR IN CONNECTION WITH ANY SUCH LOSS; AND (C) IN NO EVENT SHALL
ANY PERSONAL LIABILITY BE ASSERTED AGAINST LANDLORD IN CONNECTION WITH THIS LEASE NOR SHALL ANY RECOURSE BE HAD TO ANY OTHER PROPERTY OR ASSETS OF LANDLORD OR ANY OF LANDLORD’S OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR CONTRACTORS. UNDER NO
CIRCUMSTANCES SHALL LANDLORD OR ANY OF LANDLORD’S OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR CONTRACTORS BE LIABLE FOR INJURY TO TENANT’S BUSINESS OR FOR ANY LOSS OF INCOME OR PROFIT THEREFROM. 

37. Severability. If any clause or provision of this Lease is illegal, invalid or unenforceable under present or future laws, then and
in that event, it is the intention of the parties hereto that the remainder of this Lease shall not be affected thereby. It is also the intention of the parties to this Lease that in lieu of each clause or provision of this Lease that is illegal,
invalid or unenforceable, there be added, as a part of this Lease, a clause or provision as similar in effect to such illegal, invalid or unenforceable clause or provision as shall be legal, valid and enforceable. 

38. Signs; Exterior Appearance. Tenant shall not, without the prior written consent of Landlord, which shall not be unreasonably
withheld: (i) attach any awnings, exterior lights, decorations, balloons, flags, pennants, banners, painting or other projection to any outside wall of the Project, (ii) use any curtains, blinds, shades or screens other than
Landlord’s standard window coverings, (iii) coat or otherwise sunscreen the interior or exterior of any windows, (iv) place any bottles, parcels, or other articles on the window sills, (v) place any equipment, furniture or other
items of personal property on any exterior balcony, or (vi) paint, affix or exhibit on any part of the Premises or the Project any signs, notices, window or door lettering, placards, decorations, or advertising media of any type which can be
viewed from the exterior of the Premises. Interior signs on doors and the directory tablet shall be inscribed, painted or affixed for Tenant by Landlord at the sole cost and expense of Tenant, and shall be of a size, color and type acceptable to
Landlord. Nothing may be placed on the exterior of corridor walls or corridor doors other than Landlord’s standard lettering.

 Tenant shall have the right to display, at Tenant’s sole cost and expense and otherwise
subject to the terms and conditions of this Section 38, the maximum number of signs permitted under applicable Legal Requirements bearing Tenant name and logo on the Building in a location reasonably acceptable to Landlord
and Tenant (“Building Sign(s)”). Tenant further acknowledges and agrees that the Building Sign(s) including, without limitation, the location, size, color and type, shall be subject to Landlord’s prior written approval, which
shall not be unreasonably withheld, and shall be subject to and in compliance with applicable Legal Requirements. Tenant shall be responsible, at Tenant’s sole cost and expense, for the maintenance of the Building Sign(s), the removal of the
Building Sign(s) at the expiration or earlier termination of the Term and for the repair of all damage resulting from such removal. 
 39.
Right to Extend Term. Tenant shall have the right to extend the Term of the Lease upon the following terms and conditions: 
 (a)
Extension Rights. Tenant shall have 2 consecutive rights (each, an “Extension Right”) to extend the term of this Lease for 5 years (each, an “Extension Term”) on the same terms and conditions as this Lease
(other than with respect to Base Rent and the Work Letter) by giving Landlord written notice of its election to exercise each Extension Right at least 12 months prior to the expiration of the Base Term of the Lease or the expiration of any
prior Extension Term. 
 Base Rent shall be adjusted on the commencement date of such Extension Term and on each annual anniversary of the
commencement of such Extension Term by multiplying the Base Rent payable immediately before such adjustment by the Rent Adjustment Percentage and adding the resulting amount to the Base Rent payable immediately before such adjustment. 

(b) Rights Personal. Extension Rights are personal to Tenant and are not assignable without Landlord’s consent, which may be
granted or withheld in Landlord’s sole discretion separate and apart from any consent by Landlord to an assignment of Tenant’s interest in the Lease, except that they may be assigned in connection with any Permitted Assignment of this
Lease. 
 (c) Exceptions. Notwithstanding anything set forth above to the contrary, Extension Rights shall, at Landlord’s option,
not be in effect and Tenant may not exercise any of the Extension Rights: 
 (i) during any period of time that Tenant is in
Default under any provision of this Lease; or 
 (ii) if Tenant has been in Default under any provision of this Lease 3 or
more times, whether or not the Defaults are cured, during the 12 month period immediately prior to the date that Tenant intends to exercise an Extension Right, whether or not the Defaults are cured. 

(d) No Extensions. The period of time within which any Extension Rights may be exercised shall not be extended or enlarged by reason of
Tenant’s inability to exercise the Extension Rights. 
 (e) Termination. The Extension Rights shall, at Landlord’s option,
terminate and be of no further force or effect even after Tenant’s due and timely exercise of an Extension Right, if, after such exercise, but prior to the commencement date of an Extension Term, (i) Tenant fails to timely cure any default
by Tenant under this Lease; or (ii) Tenant has Defaulted 3 or more times during the period from the date of the exercise of an Extension Right to the date of the commencement of the Extension Term, whether or not such Defaults are cured. 

40. Miscellaneous. 
 (a)
Notices. All notices or other communications between the parties shall be in writing and shall be deemed duly given upon delivery or refusal to accept delivery by the addressee thereof if delivered in person, or upon actual receipt if
delivered by reputable overnight guaranty courier, addressed and sent to the parties at their addresses set forth above. Landlord and Tenant may from time to time by written notice to the other designate another address for receipt of future
notices.

 (b) Joint and Several Liability. If and when included within the term
“Tenant,” as used in this instrument, there is more than one person or entity, each shall be jointly and severally liable for the obligations of Tenant. 

(c) Financial Information. Tenant shall furnish Landlord with true and complete copies of (i) Tenant’s most recent
audited annual financial statements within 90 days of the end of each of Tenant’s fiscal years during the Term, (ii) Tenant’s most recent unaudited quarterly financial statements within 45 days of the end of each of Tenant’s
first three fiscal quarters of each of Tenant’s fiscal years during the Term, (iii) at Landlord’s request from time to time, but not more than once per year, updated business plans, including cash flow projections and/or pro forma
balance sheets and income statements, all of which shall be treated by Landlord as confidential information belonging to Tenant, (iv) corporate brochures and/or profiles prepared by Tenant for prospective investors, and (v) any other
financial information or summaries that Tenant typically provides to its lenders or shareholders. So long as Tenant is a “public company” and its financial information is publicly available, then the foregoing delivery requirements of this
Section 40(c) shall not apply. 
 (d) Recordation. Neither this Lease nor a memorandum of lease shall be
filed by or on behalf of Tenant in any public record. Landlord may prepare and file, and upon request by Landlord Tenant will execute, a memorandum of lease. Nothing contained in this Lease is intended to prohibit Tenant from filing this Lease with
the Securities and Exchange Commission (“SEC”) to the extent that Tenant is required to do so pursuant to applicable SEC requirements. Prior to any such filing of this Lease, Tenant shall redact the Base Rent and other economic
terms to the extent permitted by applicable SEC regulations. 
 (e) Interpretation. The normal rule of construction to the effect that
any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of this Lease or any exhibits or amendments hereto. Words of any gender used in this Lease shall be held and construed to include any other
gender, and words in the singular number shall be held to include the plural, unless the context otherwise requires. The captions inserted in this Lease are for convenience only and in no way define, limit or otherwise describe the scope or intent
of this Lease, or any provision hereof, or in any way affect the interpretation of this Lease. 
 (f) Not Binding Until Executed. The
submission by Landlord to Tenant of this Lease shall have no binding force or effect, shall not constitute an option for the leasing of the Premises, nor confer any right or impose any obligations upon either party until execution of this Lease by
both parties. 
 (g) Limitations on Interest. It is expressly the intent of Landlord and Tenant at all times to comply with applicable
law governing the maximum rate or amount of any interest payable on or in connection with this Lease. If applicable law is ever judicially interpreted so as to render usurious any interest called for under this Lease, or contracted for, charged,
taken, reserved, or received with respect to this Lease, then it is Landlord’s and Tenant’s express intent that all excess amounts theretofore collected by Landlord be credited on the applicable obligation (or, if the obligation has been
or would thereby be paid in full, refunded to Tenant), and the provisions of this Lease immediately shall be deemed reformed and the amounts thereafter collectible hereunder reduced, without the necessity of the execution of any new document, so as
to comply with the applicable law, but so as to permit the recovery of the fullest amount otherwise called for hereunder. 
 (h) Choice of
Law. Construction and interpretation of this Lease shall be governed by the internal laws of the state in which the Premises are located, excluding any principles of conflicts of laws. 

(i) Time. Time is of the essence as to the performance of Tenant’s obligations under this Lease.

 (j) OFAC. Tenant and all beneficial owners of Tenant are currently (a) in
compliance with and shall at all times during the Term of this Lease remain in compliance with the regulations of the Office of Foreign Assets Control (“OFAC”) of the U.S. Department of Treasury and any statute, executive order, or
regulation relating thereto (collectively, the “OFAC Rules”), (b) not listed on, and shall not during the term of this Lease be listed on, the Specially Designated Nationals and Blocked Persons List, Foreign Sanctions Evaders List,
or the Sectoral Sanctions Identification List, which are all maintained by OFAC and/or on any other similar list maintained by OFAC or other governmental authority pursuant to any authorizing statute, executive order, or regulation, and (c) not
a person or entity with whom a U.S. person is prohibited from conducting business under the OFAC Rules. 
 (k) Incorporation by
Reference. All exhibits and addenda attached hereto are hereby incorporated into this Lease and made a part hereof. If there is any conflict between such exhibits or addenda and the terms of this Lease, such exhibits or addenda shall control.

 (l) Entire Agreement. This Lease, including the exhibits attached hereto, constitutes the entire agreement between Landlord and
Tenant pertaining to the subject matter hereof and supersedes all prior and contemporaneous agreements, understandings, letters of intent, negotiations and discussions, whether oral or written, of the parties, and there are no warranties,
representations or other agreements, express or implied, made to either party by the other party in connection with the subject matter hereof except as specifically set forth herein. 

(m) No Accord and Satisfaction. No payment by Tenant or receipt by Landlord of a lesser amount than the monthly installment of Base Rent
or any Additional Rent will be other than on account of the earliest stipulated Base Rent and Additional Rent, nor will any endorsement or statement on any check or letter accompanying a check for payment of any Base Rent or Additional Rent be an
accord and satisfaction. Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such Rent or to pursue any other remedy provided in this Lease. 

(n) Hazardous Activities. Notwithstanding any other provision of this Lease, Landlord, for itself and its employees, agents and
contractors, reserves the right to refuse to perform any repairs or services in any portion of the Premises which, pursuant to Tenant’s routine safety guidelines, practices or custom or prudent industry practices, require any form of protective
clothing or equipment other than safety glasses. In any such case, Tenant shall contract with parties who are acceptable to Landlord, in Landlord’s reasonable discretion, for all such repairs and services, and Landlord shall, to the extent
required, equitably adjust Tenant’s Share of Operating Expenses in respect of such repairs or services to reflect that Landlord is not providing such repairs or services to Tenant. 

(o) Shuttle Services. Landlord and affiliates of Landlord plan to provide a campus shuttle service for the Project and other buildings
in the vicinity of the Project that are owned by affiliates of Landlord (the “Shuttle Service”); provided, however, that neither Landlord nor any affiliate of Landlord shall be obligated to provide the Shuttle Service
(or, once the Shuttle Service has commenced, to continue providing the Shuttle Service for any specific period of time) or to cause the Shuttle Service to follow any specific route, make any specific stops, or adhere to any specific schedule or
hours of operation. If Landlord and affiliates of Landlord actually commence operation of the Shuttle Service, (i) Landlord shall give Tenant written notice of the date such operation will commence (“Shuttle Services Commencement
Date”) and the planned route, stops, schedule, and hours of operation, (ii) Landlord shall permit Tenant’s employees actually employed at the Project to use the Shuttle Service, and (iii) regardless of whether Tenant’s
employees use the Shuttle Services, commencing on later to occur of (x) the Shuttle Services Commencement Date, or the Rent Commencement Date, through the earlier of the expiration of the Term or the date that Landlord permanently ceases to
provide Shuttle Service, Operating Expenses shall include an amount equal to $[***] per year per rentable square foot of the Premises (the “Shuttle Service Costs”) to cover the costs of providing the Shuttle Service. Tenant
acknowledges and agrees that Landlord has not made any representations or warranties regarding the commencement or continued availability of the Shuttle Service and that Tenant is not entering into this Lease with an expectation that the Shuttle
Service shall commence or continue to be available to Tenant throughout the Term. 

  
 

 

 Certain information, as identified by [***], has been excluded from this agreement because it (i) is not
material and (ii) would be competitively harmful if publicly disclosed.

 (p) Counterparts. This Lease may be executed in 2 or more counterparts, each of which
shall be deemed an original, but all of which together shall constitute one and the same instrument. Counterparts may be delivered via electronic mail (including pdf or any electronic signature process complying with the U.S. federal ESIGN Act of
2000) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes. Electronic signatures shall be deemed original signatures for purposes of this
Lease and all matters related thereto, with such electronic signatures having the same legal effect as original signatures.

 EXHIBIT C TO LEASE 

WORK LETTER 
 THIS
WORK LETTER (this “Work Letter”) is incorporated into that certain Lease Agreement (the “Lease”) dated as of August 2, 2019, by and between ARE-SEATTLE NO. 12, LLC, a
Delaware limited liability company (“Landlord”), and ADAPTIVE BIOTECHNOLOGIES CORPORATION, a Washington corporation (“Tenant”). Any initially capitalized terms used but not defined herein shall have the
meanings given them in the Lease. 
 1. General Requirements. 

(a) Tenant’s Authorized Representative. Tenant designates Arden Yang (“Tenant’s Representative”) as the only
person authorized to act for Tenant pursuant to this Work Letter. Landlord shall not be obligated to respond to or act upon any request, approval, inquiry or other communication (“Communication”) from or on behalf of Tenant in
connection with this Work Letter unless such Communication is in writing from Tenant’s Representative. Tenant may change Tenant’s Representative at any time upon not less than 5 business days advance written notice to Landlord. 

(b) Landlord’s Authorized Representative. Landlord designates Todd Chambers and Jack Wells (either such individual acting alone,
“Landlord’s Representative”) as the only persons authorized to act for Landlord pursuant to this Work Letter. Tenant shall not be obligated to respond to or act upon any request, approval, inquiry or other Communication from or
on behalf of Landlord in connection with this Work Letter unless such Communication is in writing from Landlord’s Representative. Landlord may change either Landlord’s Representative at any time upon not less than 5 business days advance
written notice to Tenant. 
 (c) Architects, Consultants and Contractors. Landlord and Tenant hereby acknowledge and agree that the
architect (the “TI Architect”) for the Tenant Improvements (as defined in Section 2(a) below), the general contractor and any subcontractors for the Tenant Improvements shall be selected by Tenant, subject
to Landlord’s approval, which approval shall not be unreasonably withheld, conditioned or delayed. Landlord shall be named a third party beneficiary of any contract entered into by Tenant with the TI Architect, any consultant, any contractor or
any subcontractor, and of any warranty made by any contractor or any subcontractor. 
 Collins Woerman Architects shall be the architect for
Landlord’s Work (as defined below) (the “Building Shell Architect”) and BN Builders shall be the general contractor for Landlord’s Work. Landlord shall select any subcontractors for Landlord’s Work in Landlord’s
sole and absolute discretion. 
 2. Landlord’s Work and Tenant Improvements. 

(a) Landlord’s Work and Tenant Improvements Defined. As used herein, (i) “Landlord’s Work” shall mean the
design and construction of the building shell (“Building Shell”) consistent with those certain 1165 Eastlake Avenue – Construction Plans and Specifications dated May 17, 2019 prepared by the Building Shell Architect
(collectively, the “Shell Plans”), and (ii) “Tenant Improvements” shall mean the design and construction of improvements to the Premises of a fixed and permanent nature as more particularly provided for in this Work
Letter. The design of the Building Shell shall be determined by Landlord in Landlord’s sole and absolute discretion and Tenant acknowledges that Landlord may make changes to the Building Shell, as determined by Landlord in its sole and absolute
discretion. Tenant may request changes to the Building Shell affecting the interior of the Building Shell and Landlord shall consider Tenant’s input and/or changes requested in good faith. Notwithstanding the foregoing, Landlord is under no
obligation to make any changes that may be requested by Tenant to the Building Shell. If Landlord does accept any changes to the Building Shell requested by Tenant, Tenant shall be responsible for any increased costs incurred by Landlord as a result
of such accepted changes (and may elect to use a portion of the TI Allowance toward such costs). Other than (i) completing Landlord’s Work, at Landlord’s sole cost and expense, and (ii) funding the TI Allowance, Landlord shall
not have any obligation whatsoever with respect to the finishing of the Premises or the Project for Tenant’s use and occupancy. 

  
 

 

			
	Work Letter – Tenant Build	  	1165 Eastlake/Adaptive - Page 2

  

 (b) Tenant’s Space Plans. Tenant shall timely deliver to Landlord schematic
drawings and outline specifications (the “TI Design Drawings”) detailing Tenant’s requirements for the Tenant Improvements. Not more than 10 business days thereafter, Landlord shall deliver to Tenant the written objections,
questions or comments of Landlord and the TI Architect with regard to the TI Design Drawings. Any disputes in connection with such comments shall be resolved in accordance with Section 2(d) hereof. Tenant shall cause the TI
Design Drawings to be revised to address such written comments and shall resubmit said drawings to Landlord for approval within 10 business days thereafter. Such process shall continue until Landlord has approved the TI Design Drawings. 

(c) Working Drawings. Not later than 90 calendar days following the approval of the TI Design Drawings by Landlord, Tenant shall cause
the TI Architect to prepare and deliver to Landlord for review and comment construction plans, specifications and drawings for the Tenant Improvements (“TI Construction Drawings”), which TI Construction Drawings shall be prepared
substantially in accordance with the TI Design Drawings. Tenant shall be solely responsible for ensuring that the TI Construction Drawings reflect Tenant’s requirements for the Tenant Improvements. Landlord shall deliver its written comments on
the TI Construction Drawings to Tenant not later than 10 business days after Landlord’s receipt of the same; provided, however, that Landlord may not disapprove any matter that is consistent with the TI Design Drawings. Tenant and the TI
Architect shall consider all such comments in good faith and shall, within 10 business days after receipt, notify Landlord how Tenant proposes to respond to such comments. Any disputes in connection with such comments shall be resolved in accordance
with Section 2(d) hereof. Provided that the design reflected in the TI Construction Drawings is consistent with the TI Design Drawings, Landlord shall approve the TI Construction Drawings submitted by Tenant. Once approved by Landlord,
subject to the provisions of Section 4 below, Tenant shall not materially modify the TI Construction Drawings except as may be reasonably required in connection with the issuance of the TI Permit (as defined in
Section 3(a) below). 
 (d) Approval and Completion. If any dispute regarding the design of the Tenant
Improvements is not settled within 10 business days after notice of such dispute is delivered by one party to the other, Tenant may make the final decision regarding the design of the Tenant Improvements, provided (i) Tenant acts reasonably and
such final decision is either consistent with or a compromise between Landlord’s and Tenant’s positions with respect to such dispute, (ii) that all costs and expenses resulting from any such decision by Tenant shall be payable out of
the TI Fund (as defined in Section 5(d) below), and (iii) Tenant’s decision will not affect the base Building, structural components of the Building or any Building Systems (in which case Landlord shall make the
final decision). Any changes to the TI Construction Drawings following Landlord’s and Tenant’s approval of same requested by Tenant shall be processed as provided in Section 4 hereof. 

(e) Coordination Obligations. “Tenant Improvement Work Readiness Condition” shall be deemed to have occurred when the
Premises is Delivered to Tenant with Landlord’s Work at such a point at which the core and shell of the Building are in a condition such that Tenant may construct the Tenant Improvements without unreasonable interference from Landlord. Tenant
acknowledges that Landlord shall continue to require access to the Building following Landlord’s Delivery to Tenant of the Premises for the construction of the Tenant Improvements in order to complete Landlord’s Work. Commencing on the
Commencement Date, Landlord and Tenant shall work together in a cooperative manner, and shall likewise require each of their respective architects and engineers and contractors to work together in a cooperative manner, to coordinate the remaining
Landlord’s Work and the Tenant Improvements and to achieve the Substantial Completion of all such work in as prompt and efficient manner as reasonably practicable so that Tenant can occupy the Premises as soon as reasonably possible following
Landlord’s Delivery of the Premises to Tenant in Tenant Improvement Work Readiness Condition.

 3. Performance of the Tenant Improvements. 

(a) Commencement and Permitting of the Tenant Improvements. Tenant shall commence construction of the Tenant Improvements upon obtaining
and delivering to Landlord a building permit (the “TI Permit”) authorizing the construction of the Tenant Improvements consistent with the TI Construction Drawings approved by Landlord. The cost of obtaining the TI Permit shall be
payable from the TI Fund. Landlord shall assist Tenant in obtaining the TI Permit. Prior to the commencement of the Tenant Improvements, Tenant shall deliver to Landlord a copy of any contract with Tenant’s contractors (including the TI
Architect), and certificates of insurance from any contractor performing any part of the Tenant Improvement evidencing industry standard commercial general liability, automotive liability, “builder’s risk”, and workers’
compensation insurance. Tenant shall cause the general contractor to provide a certificate of insurance naming Landlord, Alexandria Real Estate Equities, Inc., and Landlord’s lender (if any) as additional insureds for the general
contractor’s liability coverages required above. 
 (b) Selection of Materials, Etc. Where more than one type of material or
structure is indicated on the TI Construction Drawings approved by Tenant and Landlord, the option will be within Tenant’s reasonable discretion if the matter concerns the Tenant Improvements, and within Landlord’s reasonable discretion if
the matter concerns the structural components of the Building or any Building system. 
 (c) Tenant Liability. Tenant shall be
responsible for correcting any deficiencies or defects in the Tenant Improvements. 
 (d) Substantial Completion. Tenant shall
substantially complete or cause to be substantially completed the Tenant Improvements in a good and workmanlike manner, in accordance with the TI Permit subject, in each case, to Minor Variations and normal “punch list” items of a non-material nature which do not interfere with the use of the Premises (“Substantial Completion” or “Substantially Complete”). Upon Substantial Completion of the Tenant
Improvements, Tenant shall require the TI Architect and the general contractor to execute and deliver, for the benefit of Tenant and Landlord, a Certificate of Substantial Completion in the form of the American Institute of Architects
(“AIA”) document G704. For purposes of this Work Letter, “Minor Variations” shall mean any modifications reasonably required: (i) to comply with all applicable Legal Requirements and/or to obtain or to comply
with any required permit (including the TI Permit); (ii) to comport with good design, engineering, and construction practices which are not material; or (iii) to make reasonable adjustments for field deviations or conditions encountered during
the construction of the Tenant Improvements. 
 4. Changes. Any changes requested by Tenant to the Tenant Improvements after the
delivery and approval by Landlord of the TI Design Drawings, shall be requested and instituted in accordance with the provisions of this Section 4 and shall be subject to the written approval of Landlord, which approval
shall not be unreasonably withheld, conditioned or delayed. 
 (a) Tenant’s Right to Request Changes. If Tenant shall request
changes (“Changes”), Tenant shall request such Changes by notifying Landlord in writing in substantially the same form as the AIA standard change order form (a “Change Request”), which Change Request shall detail
the nature and extent of any such Change. Such Change Request must be signed by Tenant’s Representative. Landlord shall review and approve or disapprove such Change Request within 10 business days thereafter, provided that Landlord’s
approval shall not be unreasonably withheld, conditioned or delayed. 
 (b) Implementation of Changes. If Landlord approves such
Change, Tenant may cause the approved Change to be instituted. If any TI Permit modification or change is required as a result of such Change, Tenant shall promptly provide Landlord with a copy of such TI Permit modification or change.

 5. Costs. 

(a) Budget For Tenant Improvements. Before the commencement of construction of the Tenant Improvements, Tenant shall obtain a detailed
breakdown, by trade, of the costs incurred or that will be incurred, in connection with the design and construction of the Tenant Improvements (the “Budget”), and deliver a copy of the Budget to Landlord for Landlord’s
approval, which shall not be unreasonably withheld or delayed. The Budget shall be based upon the TI Construction Drawings approved by Landlord. The Budget shall include a payment to Landlord of administrative rent (“Administrative
Rent”) equal to [***]% of the TI Allowance (as hereinafter defined) for monitoring and inspecting the construction of the Tenant Improvements, which sum shall be payable from the TI Fund. Such Administrative Rent shall include, without
limitation, all out-of-pocket costs, expenses and fees incurred by or on behalf of Landlord arising from, out of, or in connection with, such monitoring of the
construction of the Tenant Improvements. 
 (b) TI Allowance. Landlord shall provide to Tenant a tenant improvement allowance
(collectively, the “TI Allowance”) as follows: 
 1. a “Tenant Improvement Allowance” in the maximum amount
of $[***] per rentable square foot of the Premises, which is included in the Base Rent set forth in the Lease; and 
 2. an
“Additional Tenant Improvement Allowance” in the maximum amount of $[***] per rentable square foot in the Premises, which shall, to the extent used, result in Additional Rent as set forth in Section 4(b) of
the Lease. 
 In addition to the TI Allowance, Landlord shall provide to Tenant a space planning allowance of up to $[***] per rentable
square foot of the Premises. 
 On or before October 1, 2020, Tenant shall notify Landlord how much Additional Tenant Improvement
Allowance Tenant has elected to receive from Landlord. Such election shall be final and binding on Tenant, and may not thereafter be modified without Landlord’s consent, which may be granted or withheld in Landlord’s sole and absolute
subjective discretion. 
 The TI Allowance shall be disbursed in accordance with this Work Letter. Tenant shall have no right to the use or
benefit (including any reduction to Base Rent) of any portion of the TI Allowance not required for the construction of (i) the Tenant Improvements described in the TI Construction Drawings approved pursuant to
Section 2(d) or (ii) any Changes pursuant to Section 4. Tenant shall have no right to any portion of the TI Allowance that is not disbursed before the last day of the month that is 18 months
after the Commencement Date. 
 (c) Costs Includable in TI Fund. The TI Fund shall be used solely for the payment of design, permits
and construction costs in connection with the construction of the Tenant Improvements, including, without limitation, the cost of electrical power and other utilities used in connection with the construction of the Tenant Improvements, the cost of
preparing the TI Design Drawings and the TI Construction Drawings, all costs set forth in the Budget, including Landlord’s Administrative Rent, and the cost of Changes (collectively, “TI Costs”). Notwithstanding anything to the
contrary contained herein, the TI Fund shall not be used to purchase any furniture, personal property or other non-Building system materials or equipment, including, but not be limited to, Tenant’s voice
or data cabling, non-ducted biological safety cabinets and other scientific equipment not incorporated into the Tenant Improvements. 

(d) Excess TI Costs. Landlord shall have no obligation to bear any portion of the cost of any of the Tenant Improvements except to the
extent of the TI Allowance. If at any time and from time-to-time, the remaining TI Costs under the Budget exceed the remaining unexpended TI Allowance (“Excess
TI Costs”), monthly disbursements of the TI Allowance shall be made in the proportion that the remaining TI Allowance bears to the outstanding TI Costs under the Budget, and Tenant shall fund the balance of each such monthly draw. For
purposes of any litigation instituted with regard to such amounts, those 

  
 

 

 Certain information, as identified by [***], has been excluded from this agreement because it (i) is not
material and (ii) would be competitively harmful if publicly disclosed. 

			
	Work Letter – Tenant Build	  	1165 Eastlake/Adaptive - Page 5

  

 
amounts required to be paid by Tenant will be deemed Rent under the Lease. The TI Allowance and Excess TI Costs are herein referred to as the “TI Fund.” Notwithstanding anything
to the contrary set forth in this Section 5(d), Tenant shall be fully and solely liable for TI Costs and the cost of Minor Variations in excess of the TI Allowance. 

(e) Payment for TI Costs. During the course of design and construction of the Tenant Improvements, subject to the terms of
Section 5(d), Landlord shall reimburse Tenant for TI Costs once a month against a draw request in Landlord’s standard form, containing evidence of payment of such TI Costs by Tenant and such certifications, lien
waivers (including a conditional lien release for each progress payment and unconditional lien releases for the prior month’s progress payments), inspection reports and other matters as Landlord customarily obtains, to the extent of
Landlord’s approval thereof for payment, no later than 30 days following receipt of such draw request. Upon completion of the Tenant Improvements (and prior to any final disbursement of the TI Fund), Tenant shall deliver to Landlord:
(i) sworn statements setting forth the names of all contractors and first tier subcontractors who did the work and final, unconditional lien waivers from all such contractors and first tier subcontractors;
(ii) as-built plans (one copy in print format and two copies in electronic CAD format) for such Tenant Improvements; (iii) a certification of substantial completion in Form AIA G704, (iv) a
certificate of occupancy for the Premises; and (v) copies of all operation and maintenance manuals and warranties affecting the Premises. 

6. Miscellaneous. 
 (a)
Consents. Whenever consent or approval of either party is required under this Work Letter, that party shall not unreasonably withhold, condition or delay such consent or approval, except as may be expressly set forth herein to the contrary.

 (b) Modification. No modification, waiver or amendment of this Work Letter or of any of its conditions or provisions shall be
binding upon Landlord or Tenant unless in writing signed by Landlord and Tenant. 
 (c) No Default Funding. In no event shall Landlord
have any obligation to fund any portion of the TI Allowance during any period that Tenant is in Default under the Lease.

			SUMMARY PLAN DESCRIPTION
		

		
			FOR VICE PRESIDENTS AND HIGHER
		

		
			(As amended through June 20, 2019)
		

			
	
			
				 I.
			

			
	
			
			Purpose

		
			The purpose of the ImmunoGen, Inc. Severance Pay Plan for Vice Presidents and Higher  (the “Plan”) is to provide, in the sole discretion of ImmunoGen, Inc. (the “Company”), a period of continued income and benefits (“Severance Benefits”) to eligible employees who serve in certain positions as designated by the Company, and whose employment with the Company is involuntarily terminated without Cause (as defined herein).
		

		
			 
		

		
			The Plan is designed to be an unfunded “employee welfare benefit plan,” as defined in Section 3(1) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and, accordingly, the Plan is governed by ERISA.  This document constitutes both the Plan document and the summary plan description required under ERISA.
		

		
			 
		

			
	
			
				 II.
			

			
	
			
			Eligibility

			
	
			
				 A.
			

			
	
			
			For purposes of this Plan, the term “Eligible Employee” means an employee of the Company:

			
	
			
				 1)
			

			
	
			
			who holds the position of Vice President and higher; and

			
	
			
				 2)
			

			
	
			
			whose employment with the Company is terminated by the Company without Cause.

			
	
			
				 B.
			

			
	
			
			For the avoidance of doubt, unless the Company provides otherwise in writing, Severance Benefits will NOT be paid to an employee:

			
	
			
				 1)
			

			
	
			
			terminating employment voluntarily;

			
	
			
				 2)
			

			
	
			
			on a leave of absence, whether approved or unapproved; 

			
	
			
				 3)
			

			
	
			
			terminated by the Company for Cause.  For purposes of this Plan, “Cause” means that the employee has, as determined by the Company in its sole discretion: (i) willfully committed an act or omission that materially harms the Company; (ii) been grossly negligent in the performance of the 

		 

		

			1

		

		

			ImmunoGen, Inc. Severance Pay Plan
 for Vice Presidents and Higher
As amended through June 20, 2019

		

		

			 

		

	employee’s duties to the Company; (iii) willfully failed or refused to follow the lawful and proper directives of the Chief Executive Officer or the Board of Directors of the Company (the “Board”); (iv) been convicted of, or pleaded guilty or nolo contendere, to a felony; (v) committed an act involving moral turpitude that is or is reasonably expected to be injurious to the Company or its reputation; (vi) committed an act relating to the employee’s employment or the Company involving in the good faith judgment of the Board, material fraud or theft; (vii) breached any material provision of any agreement between the employee and the Company or any nondisclosure or non-competition agreement between the employee and the Company, as all of the foregoing may be amended prospectively from time to time; or (viii) breached a material provision of any code of conduct or ethics policy in effect at the Company, as all of the foregoing may be amended prospectively from time to time (each of the foregoing hereinafter referred to as a “Violation”); provided, however, that if a Violation described in clauses (ii), (vii) or (viii) is susceptible of cure, the employee will be afforded a reasonable period (not to exceed twenty (20) business days) after receiving the initial written notice from the Company of such Violation to substantially cure such Violation prior to the Company taking any action to terminate the employee’s employment for Cause;

			
	
			
				 4)
			

			
	
			
			if the employee has been offered another reasonably comparable position with the Company, whether or not the employee accepts such offer; or

			
	
			
				 5)
			

			
	
			
			if the employee is entitled to receive severance compensation under the terms of any separate written agreement, including, without limitation, any change in control severance agreement or employment agreement, between the Company and the employee in connection with the termination of the employee’s employment following a change in control of the Company or otherwise.

		
			For purposes of clause (4) above, whether an offer is “reasonably comparable” will be determined by the Company in its sole reasonable discretion.  The Company shall, but is not necessarily limited to, consider the following factors in making such determination: (a) the change in commute; (b) a comparison of the offered annual base salary against the employee’s then current annual base salary; and (c) whether the employee is reasonably capable of performing the responsibilities of the position by training or experience.
		

			
	
			
				 C.
			

			
	
			
			Notwithstanding any provisions of this Plan to the contrary, the Company shall not be obligated to pay the employee and the employee shall not be eligible to receive any Severance Benefits set forth in Section III unless the employee executes, delivers, and does not revoke a “separation agreement” within the time period set forth in the separation agreement.  The separation agreement generally will include:

			
	
			
				 ·
			

			
	
			
			a release of claims;

			
	
			
				 ·
			

			
	
			
			a non-disparagement agreement;

				 ·
			

			
	
			
			a non-competition agreement;

			
	
			
				 ·
			

			
	
			
			a non-solicitation agreement; and

			
	
			
				 ·
			

			
	
			
			such other provisions that the Company may require.

		
			 
		

			
	
			
				 III.
			

			
	
			
			Severance Benefits

		
			Provided that an Eligible Employee satisfies all conditions for receipt in accordance with the terms of this Plan, an Eligible Employee shall be entitled to the following Severance Benefits:
		

			
	
			
				 A.
			

			
	
			
			Severance Pay

		
			An Eligible Employee will receive Severance Pay in accordance with the following schedule:
		

			
					
						Chief Executive Officer

					
					
						18 months

				
	
					
						Executive Officer (as designated by the Board) 

					
					
						12 months

				
	
					
						Vice President (other than Executive Officer)

					
					
						Two (2) weeks of salary for each year of service, subject to a minimum Severance Pay level of 26 weeks and a maximum Severance Pay level of 52 weeks

				

		
			Severance Pay will be calculated on the basis of the Eligible Employee’s highest annualized base salary in the 12 months preceding the date of termination of employment with the Company (the “Termination Date”).
		

		
			For these purposes, an Eligible Employee who is a Vice President (other than an Executive Officer) is entitled to credit for a year of service for each 12 month period of continuous service commencing on the Eligible Employee’s date of hire (or in the case of an Eligible Employee who has more than one period of service with the Company, the most recent date of hire); provided however, that credit for a full year of service will be given if the Termination Date is six (6) months or more from the most  recent anniversary date of the Eligible Employee’s date of hire (or most recent date of hire as noted above).
		

		
			Severance Pay will be paid by means of salary continuation payments commensurate with the Company’s normal payroll cycles, for the duration of the period described above (the “Severance Period”), to commence as soon as practicable following the effective date of the separation agreement, but no later than sixty (60) days following the Termination Date, subject to the provisions of Section II(C) and Section IV.  In case of the death of an Eligible Employee before the completion of all Severance Payments, any remaining Severance Payments will be paid in a lump sum to the beneficiary or beneficiaries as set forth in the Eligible

Employee’s beneficiary designation under the Company’s group life insurance program as in effect on the Eligible Employee’s Termination Date, as soon as administratively feasible, but in no event later than sixty (60) days following the Company’s receipt of notice of the Eligible Employee’s death.  If no such beneficiary designation is in effect on the Termination Date, or if no such designated beneficiary(ies) survive the Eligible Employee, the remaining Severance Payments will be paid to Eligible Employee’s estate.
		

			
	
			
				 B.
			

			
	
			
			Annual Bonus

			
	
			
				 1)
			

			
	
			
			If not already paid on or prior to the Termination Date, an Eligible Employee will be entitled to receive a payment equal to his or her annual bonus related to the most recently completed calendar year, determined in accordance with the terms of the Company’s annual bonus program, if, as and when bonuses are paid to employees who were similarly situated officers of the Company as of the end of the most recently completed fiscal year.

			
	
			
				 2)
			

			
	
			
			For the calendar year in which the Eligible Employee’s termination occurs, the Eligible Employee will be entitled to receive his or her annual bonus related to such year, determined in accordance with the Company’s annual bonus program, if, as and when bonuses are paid to employees who were similarly situated officers of  the Company as of end of such year, provided that such bonus will be pro-rated to reflect the actual number of days the Eligible Employee was employed during the applicable calendar year.

		
			Any annual bonus amounts due to the Eligible Employee will be paid to the Eligible Employee at the same time bonuses are paid to other participants in the Company’s annual bonus program.  In case of the death of an Eligible Employee before payment of the annual bonus amounts due to the Eligible Employee, such bonus amounts will be paid to the beneficiary or beneficiaries as set forth in the Eligible Employee’s beneficiary designation under the Company’s group life insurance program as in effect on the Eligible Employee’s Termination Date.  If no such beneficiary designation is in effect on the Termination Date, or if no such designated beneficiary(ies) survive the Eligible Employee, the bonus amounts will be paid to the Eligible Employee’s estate.
		

			
	
			
				 C.
			

			
	
			
			COBRA Premium

		
			If an Eligible Employee timely elects to continue medical and dental coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”), the Company will subsidize such Eligible Employee’s COBRA premium at the same rate the Company subsidizes coverage for similarly situated active employees, as such subsidy may be modified from time-to-time.    In the event that the Company determines that the COBRA premium subsidy is taxable income to Eligible Employees, the income will be reported on Form W-2 as imputed income.  The COBRA premium subsidy will continue for the duration of the

Eligible Employee’s Severance Period, or until COBRA ends, if earlier.  Upon the cessation of the COBRA premium subsidy, the Eligible Employee will be entitled to continue his or her medical and/or dental coverage for the duration of the COBRA continuation period, if any, at the Eligible Employee’s own cost.
		

			
	
			
				 D.
			

			
	
			
			Outplacement Services

		
			Outplacement services lasting not less than 6 months will be provided at a level to be determined by the Company in its sole discretion.  If an Eligible Employee fails to commence utilization of the outplacement services provided by the Company within 60 days of his or her Termination Date, the outplacement services shall be forfeited.  In no event will an Eligible Employee be entitled to the cash value of the outplacement services in lieu of the outplacement services.

			Conditions Governing Payment

			
	
			
				 A.
			

			
	
			
			In addition to the satisfaction of any conditions set forth above, an Eligible Employee will only receive such Severance Benefits if the Company determines that the Eligible Employee has satisfied the following:

			
	
			
				 1)
			

			
	
			
			the Eligible Employee must continue to be actively at work to the satisfaction of the Company through the last day of work designated and as determined by the Company, in its sole discretion, unless the Eligible Employee’s absence is covered by the Company’s paid time off policy, or if the Company, in its sole discretion, has agreed in writing to adjust the Eligible Employee’s last day of work to an earlier date than previously scheduled; and

			
	
			
				 2)
			

			
	
			
			the Eligible Employee must have returned all Company property and settled satisfactorily all expenses owed to the Company.

			
	
			
				 B.
			

			
	
			
			Any Severance Benefits to which the Eligible Employee may be entitled will be offset, in the sole discretion of the Company, by any amounts the Eligible Employee may owe the Company, such as pay for time under the Company’s paid time off policy the Eligible Employee may have been advanced but was not earned at the time of termination, unauthorized or un-reconciled business expenses, and the value of any Company equipment in the Eligible Employee’s possession which the Eligible Employee has not returned to the Company.

			
	
			
				 C.
			

			
	
			
			Any Severance Benefits for which the Eligible Employee may be eligible will be reduced by the amount of paid administrative leave provided to the Eligible Employee during any notice period required by the Worker Adjustment and Retraining Notification (WARN) Act. Alternatively, if the WARN Act applies and the Company provides the Eligible Employee less than 60 days’ notice, the Company may choose to pay out pay and benefits owed instead of providing the Eligible Employee paid administrative leave. In that event, any Severance Benefits

	for which the Eligible Employee may be eligible will be reduced by the amount of pay and benefits provided in lieu of notice.

			
	
			
				 D.
			

			
	
			
			Any Severance Benefits to which an Eligible Employee may be entitled shall immediately cease upon the determination by the Company that such Eligible Employee violated the terms of the separation agreement or the Proprietary Information, Inventions and Competition Agreement between the Company and the Eligible Employee.

			
	
			
				 V.
			

			
	
			
			Reemployment

		
			If rehired by the Company, any Severance Benefits to which an Eligible Employee may be entitled shall cease with the payment for the period ending the day immediately preceding the date of rehire.
		

			
	
			
				 VI.
			

			
	
			
			Plan Continuance

		
			The Company expects to continue this Plan indefinitely, but reserves the right to amend or terminate the Plan, or any portion of the Plan, at any time in its sole discretion by action of the Board.  Further, the Company, by action of the Board, reserves the right to modify the benefits set forth in this Plan, or to pay such other benefits as it may, in its sole discretion, deem appropriate, in addition to or in lieu of the benefits set forth in this Plan.  Notwithstanding the above, any amendment or modification to the Plan that decreases benefits available under the Plan will apply only to those employees who have a Termination Date after the effective date of such modification or amendment.
		

			
	
			
				 VII.
			

			
	
			
			Administration of the Plan

		
			The Company, acting through the Head of Human Resources (“HHR”), shall be the Plan Administrator.  The Plan Administrator shall have sole authority and discretion to administer and construe the terms of this Plan, subject to applicable requirements of law.  Without limiting the generality of the foregoing, the Plan Administrator shall have complete discretionary authority to carry out the following powers and duties:
		

			
	
			
				 1)
			

			
	
			
			to make and enforce such rules and regulations as it deems necessary or proper for the efficient administration of the Plan;

			
	
			
				 2)
			

			
	
			
			to interpret and construe the Plan, its interpretations and constructions thereof to be final and conclusive on all persons claiming Severance Benefits under the Plan;

			
	
			
				 3)
			

			
	
			
			to decide all questions, including without limitation, issues of fact, concerning the Plan, including the eligibility of any person to participate in, and receive Severance Benefits under the Plan; and

			to appoint such agents, counsel, accountants, consultants and other persons as may be required to assist in the administration of the Plan.

			Claim and Claim Appeal Procedures

		
			Employees who are eligible for Severance Payments under this Plan will be notified by the Company.  If you believe that you did not receive the Severance Benefits to which you were entitled, you need to make a claim with the Director, Human Resources Business Partner (the “HR Business Partner”). The HR Business Partner will review and make a decision with respect to your claim within 90 days of receipt of your claim, unless the HR Business Partner determines that special circumstances require an extension of time for processing the claim, in which case you will receive a written notice of the extension before termination of the initial 90-day period.  The extension notice will indicate the special circumstances requiring the extension and the date by which the HR Business Partner expects to render the benefit determination.
		

		
			If any claim is denied in whole or in part, you or your beneficiary will receive written notification within 90 days, including the reasons for the denial; reference to the specific Plan provisions on which the denial was based; information about additional material needed to pursue the claim, if any, and why such material is needed; and an explanation of the claim appeal procedure including a statement of your right to bring a civil action under § 502(a) of ERISA following an adverse benefit determination on appeal.  Within 60 days, you or your beneficiary may submit a written request for reconsideration of the claim to the HHR.
		

		
			You or your representative may submit written comments, documents, records, and other information relating to the claim for Severance Benefits.  Upon request and free of charge, you or your representative may have reasonable access to, and copies of, all documents, records, and other information relevant to your claim for Severance Benefits.
		

		
			The review by the HHR will take into account all comments, documents, records, and other information you submit relating to the claim, without regard to whether such information was submitted or considered in the initial Severance Benefits determination.
		

		
			The HHR will make a decision on your appeal within 60 days after the receipt of the appeal.  If the HHR determines that special circumstances require an extension of time for processing the appeal, you will receive a written notice of the extension before the end of the initial 60-day period.  The extension notice shall indicate the special circumstances requiring the extension and the date by which the Plan expects to render the determination on appeal.
		

		
			If your appeal is denied in whole or in part, you will receive a written notification including the reasons for the denial; reference to the specific Plan provisions on which the denial was based; a statement that you are entitled to receive, upon request and free of charge, reasonable access to, and copies of, all documents, records, and other information relevant to your claim for Severance Benefits; and a statement describing any voluntary appeal procedures offered by the Plan and your right to obtain information about such procedures, as well as a statement of your right to bring a civil action under § 502(a) of ERISA.
		

		
			The HHR will decide whether a hearing will be held on the claim and will notify you at least 14 days before the hearing, if one is to be held.

			To the extent permitted by law, decisions reached under the claims procedures set forth in this Section VIII shall be final and binding on all parties.  No action (whether at law, in equity or otherwise) shall be brought by or on behalf of any participant or Beneficiary for or with respect to benefits due under this Plan unless the person bringing such action has timely exhausted the Plan’s claim review procedure.  In any such legal action, the claimant may only present evidence and theories which the claimant presented during the claims procedure.  Any claims which the claimant does not in good faith pursue through the review stage of the procedure shall be treated as having been irrevocably waived.  Judicial review of a claimant’s denied claim shall be limited to a determination of whether the denial was an abuse of discretion based on the evidence and theories the claimant presented during the claims procedure.
		

		
			Any action (whether at law, in equity or otherwise) must be commenced within one (1) year and must be brought in a court of competent jurisdiction sitting in Waltham, Massachusetts.  This one (1) year period shall be computed from the earlier of: (a) the date a final determination denying such benefit, in whole or in part, is issued under the Plan’s claim review procedure; and (b) the date such individual’s cause of action first accrued (as determined under the laws of the Commonwealth of Massachusetts without regard to principles of choice of laws).
		

			
	
			
				 IX.
			

			
	
			
			Your Rights Under ERISA

		
			As a participant in the Plan you are entitled to certain rights and protections under ERISA.  ERISA provides that all Plan participants shall be entitled to:
		

			
	
			
				 A.
			

			
	
			
			Receive Information About Your Plan and Benefits

			
	
			
				 1)
			

			
	
			
			Examine, without charge, at the Plan Administrator’s office and at other specified locations, such as worksites and union halls, all documents governing the Plan, including insurance contracts, and a copy of the latest annual report (Form 5500 Series) filed by the Plan with the U.S. Department of Labor and available at the Public Disclosure Room of the Employee Benefits Security Administration.

			
	
			
				 2)
			

			
	
			
			Obtain, upon written request to the Plan Administrator, copies of documents governing the operation of the Plan, including insurance contracts, and copies of the latest annual report (Form 5500 Series) and updated summary plan description.  The Plan Administrator may make a reasonable charge for the copies.

			
	
			
				 B.
			

			
	
			
			Prudent Actions by Plan Fiduciaries

		
			In addition to creating rights for Plan participants, ERISA imposes duties upon the people who are responsible for the operation of the Plan.  The people who operate your plan, called “fiduciaries” of the Plan, have a duty to do so prudently and in your interest and that of other Plan participants and beneficiaries.  No one, including your employer or any other person, may fire you or otherwise discriminate against you in any way to prevent you from obtaining a welfare benefit or exercising your rights under ERISA.

				 C.
			

			
	
			
			Enforce Your Rights

		
			If your claim for a welfare benefit is denied or ignored, in whole or in part, you have a right to know why this was done, to obtain copies of documents relating to the decision without charge, and to appeal any denial, all within certain time schedules.
		

		
			Under ERISA, there are steps you can take to enforce the above rights.  For instance, if you request a copy of Plan documents or the latest annual report from the Plan and do not receive them within 30 days, you may file suit in a federal court.  In such a case, the court may require the Plan Administrator to provide the materials and pay you up to $110 a day until you receive the materials, unless the materials were not sent because of reasons beyond the control of the Plan Administrator.  If you have a claim for benefits which is denied or ignored, in whole or in part, you may file suit in a state or federal court.  If it should happen that Plan fiduciaries misuse the Plan’s money, or if you are discriminated against for asserting your rights, you may seek assistance from the U.S. Department of Labor, or you may file suit in a federal court.  The court will decide who should pay court costs and legal fees.  If you are successful, the court may order the person you have sued to pay these costs and fees.  If you lose, the court may order you to pay these costs and fees, for example, if it finds your claim is frivolous.
		

			
	
			
				 D.
			

			
	
			
			Assistance with Your Questions

		
			If you have questions about the Plan, you should contact the Plan Administrator.  If you have any questions about this statement or about your rights under ERISA, or if you need assistance in obtaining documents from the Plan Administrator, you should contact the nearest office of the Employee Benefits Security Administration, U.S. Department of Labor, listed in your telephone directory or the Division of Technical Assistance and Inquiries, Employee Benefits Security Administration, U.S. Department of Labor, 200 Constitution Avenue N.W., Washington, D.C. 20210.  You may also obtain certain publications about your rights and responsibilities under ERISA by calling the publications hotline of the Employee Benefits Security Administration.

			Tax Information

		
			It is intended that this Plan: (i) be exempt from the requirements of Section 409A of the Internal Revenue Code (the “Code”) of 1986 (“Section 409A”) to the maximum extent possible (under the short-term deferral rules of Treasury Regulation Section 1.409A-1(b)(4)(i) and/or the exemption for involuntary terminations under the separation pay plan rules of Treasury Regulation Section 1.409A-1(b)(9)(iii)).
		

		
			If this Plan is not exempt from the requirements of Section 409A of the Code, or to the extent the Plan is not so exempt, it is intended that the Plan comply with the requirements of Section 409A of the Code and the Plan shall be interpreted, operated and administered accordingly, including:
		

		
			(i)The phrase termination of employment, or any derivation thereof, shall mean a “separation from service” within the meaning of Code Section 409A.

As amended through June 20, 2019

		

		

			 

		

		

		
			(ii)To the extent that this Plan requires that a payment shall be made following the execution of a waiver and release agreement, such payment or payments will only be made if the waiver and release agreement is executed prior to the 60th day following the Termination Date; provided, that if this 60 day period commences in one tax year and ends in the next tax year, no payment which is the subject of such waiver and release agreement may be made or commence (in the case of a series of payments), until the second of the tax years.  The Employee may not designate the year of such payment.
		

		
			(iii)To the extent that this Plan provides for the reimbursement of specified expenses incurred by an Eligible Employee, such reimbursement shall be made in accordance with the provisions of this Plan, but in no event later than the last day of the Eligible Employee’s taxable year following the taxable year in which the expense was incurred.  The amount of expenses eligible for reimbursement in any taxable year of the Eligible Employee shall not affect the amount of expenses to be reimbursed or provided in any other year (except in the case of maximum benefits to be provided under a medical reimbursement arrangement, if applicable).
		

		
			(iv)Payments in respect of an Eligible Employee’s termination of employment under this Plan are designated as separate payments for purposes of the short-term deferral rules under Treasury Regulation Section 1.409A-1(b)(4)(i)(F) and the exemption for involuntary terminations under separation pay plans under Treasury Regulation Section 1.409A-1(b)(9)(iii).  As a result, (a) any payments that become vested as a result of the Eligible Employee’s termination of employment under this Plan that are made on or before the 15th day of the third month of the later of the calendar year or Company fiscal year following the calendar or fiscal year of the Eligible Employee’s termination of employment, and (b) any additional payments that are made on or before the last day of the second calendar year following the year of the Eligible Employee’s termination of employment and do not exceed the lesser of two times base salary or two times the limit under Code Section 401(a)(17) then in effect, and (c) the payment of medical expenses within the applicable COBRA period, are exempt from the requirements of Code Section 409A.
		

		
			(v)Notwithstanding any other provision with respect to the timing of payments under Section III, if, at the time of Eligible Employee’s termination, Eligible Employee is deemed to be a “specified employee” (within the meaning of Section 409A, and any successor statute, regulation and guidance thereto) of the Company, then solely to the extent necessary to comply with the requirements of Section 409A, any payments to which Eligible Employee may become entitled under Section III which are subject to Section 409A (and not otherwise exempt from its application) will be withheld until the first (1st) business day of the seventh (7th) month following the Termination Date, at which time Eligible Employee shall be paid an aggregate amount equal to the accumulated, but unpaid, payments otherwise due to Eligible Employee under the terms of Section III.
		

		
			Notwithstanding anything in this Plan to the contrary, the Company does not guarantee the tax treatment of any Severance Benefits under this Plan, including without limitation pursuant to the Code, federal, state or local tax laws or regulations.
