  b.Acceptance of Premises. Except as specified elsewhere in this Sublease, Tenant makes no representations or warranties to Subtenant regarding the Subleased Premises, including the structural condition of the Subleased Premises or the condition of all mechanical, electrical, and other systems on the Subleased Premises. Except for any subtenant improvements to be completed by Tenant as described in the Work Letter attached as Exhibit 4 (“Tenant’s Work”), Subtenant shall accept the Subleased Premises and its appurtenances in their respective AS-IS, WHERE-IS condition, and shall further be responsible for performing any work necessary to bring the Subleased Premises into a condition satisfactory to Subtenant. By signing this Sublease, Subtenant acknowledges that it has had adequate opportunity to investigate the Subleased Premises, acknowledges responsibility for making any corrections, alterations and repairs to the Subleased Premises (other than Tenant’s Work), and acknowledges that the time needed to complete any such items shall not delay the Sublease Commencement Date.  However, Sublandlord shall at its cost deliver the Subleased Premises to Subtenant (i) broom clean; and (ii) with the Tenant’s Work (cap of the stairwell) substantially completed.  Sublandlord further agrees to work in good faith with Subtenant and Landlord to facilitate Subtenant’s use of existing cabling infrastructure within the Subleased Premises (while ensuring that Sublandlord’s data and network security and performance is not compromised).  To Sublandlord’s knowledge, all lighting, electrical outlets, and any other electrical/mechanical systems are in a fully functional condition consistent with a class A building in Seattle.  Notwithstanding anything to the contrary in this Sublease, Subtenant shall have no obligation to correct any defects in the Subleased Premises (including, without limitation, any condition that is a default under the Master Lease) existing as of the Commencement Date of this Sublease, and Sublandlord shall be responsible at its cost for correcting any such defects or defaults to the extent such obligations are Sublandlord’s obligation to maintain pursuant to the Master Lease.

  c.Subtenant Improvements. The Work Letter attached as Exhibit 4 sets forth all of Tenant’s Work, if any, and all improvements to be completed by Subtenant (“Subtenant’s Work”), if any, that will be performed on the Subleased Premises. Responsibility for design, payment and performance of all such work shall be as set forth in the Work Letter.

  3.TERM. The term of this Sublease shall commence on the Commencement Date and shall end on the Termination Date (the “Term”).

  a.Early Possession. Subtenant acknowledges that Tenant may need to obtain Landlord’s consent to this Sublease prior to Subtenant occupying the Subleased Premises, and that Subtenant shall not occupy the Subleased Premises without the prior written consent of Tenant. In the event Tenant gives Subtenant access to the Subleased Premises preceding the Sublease Commencement Date for the purpose of installing Subtenant’s furniture, telecommunications, fixtures, telephone systems and computer cabling and the performance of Subtenant’s Work, if any, such access shall be fully coordinated with Tenant in advance and Subtenant shall not interfere with Tenant’s Work. In no event shall Subtenant have access to any portion of the Master Premises except for the Subleased Premises. All of the terms and conditions of this Sublease, including Subtenant’s insurance and indemnification obligations, shall apply during such time, except for payment of Base Rent. If Subtenant occupies the Subleased Premises before the Sublease Commencement Date specified in Section 1, then such date of occupancy shall not advance the Sublease Commencement Date or Sublease Termination Date set forth above.

  b.Delayed Possession. Tenant shall act diligently to make the Subleased Premises available to Subtenant, provided, however, that neither Tenant nor any agent or employee of Tenant shall be liable for any damage or loss due to Tenant’s inability or failure to deliver possession of the Premises to Subtenant as provided in this Sublease. If possession is delayed, the Sublease Commencement Date set forth in Section 1 shall also be delayed, but the Sublease Termination Date shall not be extended by such delay. If the Sublease Commencement Date does not occur within ___days ((60) days if not filled in) after the mutual execution and delivery of this Sublease : ☒ Subtenant may elect to cancel this Sublease by giving written notice to Tenant no later than ((10) days if not filled in) after such time period ends, or ☐ then all Base Rent and Additional Rent (as defined below) shall be abated for each one (1) day after the Sublease Commencement Date during which possession of the Subleased Premises has not been delivered to Subtenant. If Subtenant gives notice of cancellation, as Subtenant’s sole and exclusive remedy, this Sublease shall be cancelled, all prepaid rent and security deposits shall be refunded to Subtenant, and neither Tenant nor Subtenant shall have any further obligations to the other.

   

  Notwithstanding anything in this Section 3 to the contrary, to the extent that any portions of the Tenant’s Work or the Subtenant’s Work have not been completed in time for the Subtenant to occupy or take possession of the Subleased Premises on the Sublease Commencement Date due to the failure of Subtenant to fulfill any of its obligations under this Sublease (“Subtenant Delays”), the Sublease shall nevertheless commence on the Sublease Commencement Date, including without limitation, Subtenant’s obligation to pay Base Rent and Additional Rent, as set forth in Section 1, or upon the date that the Sublease Commencement Date would have occurred but for the Subtenant Delays.

  4.RENT

  a.Payment of Rent. Subtenant shall pay Tenant without notice, demand, deduction or offset, in lawful money of the United States, the monthly Base Rent stated in Section 1 in advance on or before the first day of each month during the Sublease Term beginning on (check one): ☒  the Sublease Commencement Date, or ☐ ___ (if no date specified, then on the Sublease Commencement Date), and any other additional payments due to Tenant (“Additional Rent”, and together with Base Rent, the “Rent”) when required under this Sublease. Payments for any partial month during the Term shall be prorated. All payments due to Tenant under this Sublease, including late fees and interest, shall also constitute Additional Rent, and upon Subtenant’s failure to pay any such costs, charges or expenses, Tenant shall have the same rights and remedies as otherwise provided in this Sublease for the failure of Subtenant to pay Rent.

  b.Late Charges; Default Interest. If any sums payable by Subtenant to Tenant under this Sublease are not received within five (5) days of their due date, Subtenant shall pay Tenant an amount equal to the sum which would be payable by Tenant to the Landlord for or 5% of the delinquent amount for the cost of collecting and handling such late payment in addition to the amount due and as Additional Rent, whichever is greater. All delinquent sums not paid by Subtenant within five (5) business days of the due date shall, at Tenant’s option, bear interest at the rate the Tenant would pay the Landlord under the Master Lease for an equivalent default or the highest rate of interest allowable by law, whichever is less. Interest on all delinquent amounts shall be calculated from the original due date to the date of payment.

  c.Less Than Full Payment. Tenant’s acceptance of less than the full amount of any payment due from Subtenant shall not be deemed an accord and satisfaction or compromise of such payment unless Tenant specifically consents in writing to payment of such lesser sum as an accord and satisfaction or compromise of the amount which Tenant claims. Any portion that remains to be paid by Tenant shall be subject to the late charges and default interest provisions of this Section.

  5.SECURITY DEPOSIT. Upon execution of this Sublease, Subtenant shall deliver to Tenant the security deposit specified in Section 1 above. Tenant’s obligations with respect to the security deposit are those of a debtor and not of a trustee, and Tenant may commingle the security deposit with its other funds. If Subtenant defaults in the performance of any covenant or condition of this Sublease, Tenant shall have the right, but not the obligation, to use or retain all or any portion of the security deposit for the payment of: (i) Base Rent, Additional Rent, or any other sum as to which Subtenant is in default; or (ii) the amount Tenant spends or may become obligated to spend, or to compensate Tenant for any losses incurred by reason of Subtenant’s default. Subtenant acknowledges, however, that the security deposit shall not be considered as a measure of Subtenant’s damages in case of default by Subtenant, and any payment to Tenant from the security deposit shall not be construed as a payment of liquidated damages for Subtenant’s default. If at any time during the Term of the Sublease the security deposit delivered by Subtenant becomes insufficient to cover the amounts required under this Section 5, whether or not due to Tenant’s application of all or a portion of the security deposit contemplated by this Section, Subtenant shall, within five (5) days after written demand therefore by Tenant, deposit with Tenant an amount sufficient to replenish the security deposit to the amount required in Section 1 above. If Subtenant is not in default of any covenant or condition of this Sublease at the end of the Term, Tenant shall return any unused portion of the security deposit without interest within 30 days after the surrender of the Subleased Premises by Subtenant in the condition required by Section 9 of this Sublease.

  6.MASTER LEASE. Tenant represents to Subtenant that as of the effective date of this Sublease: (a) Tenant has delivered to Subtenant a complete copy of the Master Lease (which may contain redacted business terms), which represents all agreements between Landlord and Tenant relating to the leasing, use, and occupancy of the Subleased Premises, and (b) Tenant has not received notice from Landlord of a breach under the Master Lease that is uncured as of the date of mutual execution and delivery of this Sublease. Tenant shall not agree to an amendment to the Master Lease which would have an adverse effect on Subtenant’s occupancy of the Subleased Premises or its intended use of the Subleased Premises, without obtaining Subtenant’s prior written consent, which consent shall not be unreasonably withheld, conditioned, or delayed. Subtenant represents that it has read and is familiar with the terms of the Master Lease.

   

  This Sublease is subject to and subordinate to the Master Lease. If the Master Lease terminates, this Sublease shall automatically terminate. Tenant and Subtenant shall not, by their omission or act, do or permit anything to be done which would cause a default under the Master Lease. If the Master Lease terminates or is forfeited as a result of a default or breach by Tenant or Subtenant under this Sublease and/or the Master Lease, then the defaulting party shall be liable to the non-defaulting party for the actual damage suffered as a result of such termination or forfeiture provided that in no event shall one party be liable to the other for consequential damages. Tenant shall exercise diligent, commercially reasonable efforts to cause Landlord to perform its obligations under the Master Lease for the benefit of the Subtenant, provided that in no event shall the foregoing requirements require Tenant to file a lawsuit.

  Except as set forth below and except as may be inconsistent with the terms contained in this Sublease, all the terms, covenants and conditions contained in the Master Lease are incorporated into and made a part of this Sublease by this reference with the following modified definitions : (i) all references in the Master Lease to “Landlord” shall be deemed to mean Tenant, (ii) all references in the Master Lease to “Tenant” shall be deemed to mean Subtenant, (iii) all references in the Master Lease to “Lease” shall mean this Sublease, (iv) all references in the Master Lease to “Premises” shall mean Subleased Premises, (v) all references in the Master Lease to “Commencement Date” shall mean Sublease Commencement Date, and (vi) all references in the Master Lease to “Term” shall mean “Sublease Term”. Tenant and Subtenant agree that as between Tenant and Subtenant the following terms of the Master Lease shall not be incorporated into this Sublease:  the entire Lease Summary; Sections 1.1, 1.3, 1.5, 1.6, 2, 3, 4, 7, 8.1.9, 8.6, 10, 11, 15, 16, 18, and 20, 22.14, 22.17, 22.18, Exhibits A, C, D, E, G, and H. Notwithstanding the foregoing incorporation of the terms and conditions of the Master Lease, Tenant shall not be responsible for the performance of any obligations to be performed by Landlord under the Master Lease, and Subtenant agrees to look solely to Landlord for the performance of such obligations.  Tenant shall not be liable to Subtenant for any failure by Landlord to perform its obligations under the Master Lease, nor shall such failure by Landlord excuse performance by Subtenant of its obligations hereunder. The parties acknowledge that Subtenant has no “Guarantor” as defined in the Master Lease, and no performance of obligations by or notice to any guarantor shall be required under the terms of this Sublease. 

  7.CONSENT OF LANDLORD.  Notwithstanding anything to the contrary in this Sublease, whenever the consent of Landlord is required under the Master Lease, Subtenant shall obtain the consent of both Tenant and Landlord, but in all instances Subtenant shall first request and obtain the consent of Tenant before requesting the consent of Landlord. This Sublease shall not become effective until Landlord has provided its written consent to this Sublease.  If Landlord does not consent to this Sublease within sixty (60) days of the parties’ execution of this Sublease, then this Sublease shall be deemed void and the parties shall have no further rights or obligations hereunder.

  8.ALTERATIONS. Subtenant may make alterations, additions or improvements to the Subleased Premises (the “Alterations”), only with the prior written consent of Tenant which shall not be unreasonably withheld, conditioned or delayed, and, to the extent required by the Master Lease, Landlord. The term “Alterations” shall not include: (i) any of Subtenant’s Work approved by Tenant pursuant to Exhibit 4, and (ii)the installation of shelves, movable partitions, or Subtenant’s equipment and trade fixtures, which may be installed and removed without damaging existing improvements or the structural integrity of the Subleased Premises, Master Premises, Building, or Property, and Tenant’s consent shall not be required for Subtenant’s installation of those items except to the extent Tenant must obtain the consent of Landlord under the Master Lease for such installations. Subtenant shall perform all work within the Subleased Premises at Subtenant’s expense in compliance with all applicable laws and shall complete all Alterations in accordance with plans and specifications approved by Tenant, using contractors approved by Tenant, and in a manner so as to not unreasonably interfere with other tenants. Subtenant shall pay when due, all claims for labor or materials furnished to or for Subtenant at or for use in the Subleased Premises, which claims are or may be secured by any mechanics’ or materialmens’ liens against the Subleased Premises or Property or any interest therein. Except as otherwise provided in the Work Letter attached as Exhibit 4 with respect to Subtenant’s Work, Subtenant shall remove all Alterations at the end of the Sublease term unless Tenant conditioned its consent upon Subtenant leaving a specified Alteration at the Subleased Premises, in which case Subtenant shall not remove such Alteration and it shall become Tenant’s property. Subtenant shall immediately repair any damage to the Subleased Premises or adjacent portions of the Master Premises, Building and Property caused by installation and/or removal of improvements performed as part of Subtenant’s Work and/or Alterations. Notwithstanding anything to the contrary, Subtenant shall have no obligation to remove or restore any alterations or improvements present upon the Subleased Premises as of the Commencement Date of this Sublease.  Subtenant shall remove any cabling that was installed in the Subleased Premises by Subtenant only upon request by Tenant.

  9.REPAIRS AND MAINTENANCE; SURRENDER. Subtenant shall, at its sole cost and expense, maintain the Subleased Premises in good condition and promptly make all repairs and replacements, whether structural or non-structural, necessary to keep the Subleased Premises safe and in good condition, including all utilities and other systems serving the Subleased Premises. Subtenant shall not damage any demising wall or disturb the structural integrity of the Subleased Premises and shall promptly repair any damage or injury done to any such demising walls or structural elements caused by Subtenant or its employees, officers, agents, servants, contractors, customers, clients, visitors, guests, or other licensees or invitees. If Subtenant fails to maintain or repair the Subleased Premises, Tenant may enter the Subleased Premises and perform such repair or maintenance on behalf of Subtenant. In such case, Subtenant shall be obligated to pay to Tenant immediately upon receipt of demand for payment, as Additional Rent, all costs incurred by Tenant in performing such repair or maintenance on behalf of Subtenant. Subtenant shall be obligated to repair or maintain only those portions of the Subleased Premises as required of Tenant under the Master Lease. Tenant shall not be required to perform any maintenance, repairs, or improvements that are the obligation of Landlord under the Master Lease (provided that Tenant shall exercise diligent, commercially reasonable efforts to cause Landlord to perform its obligations under the Master Lease for the benefit of the Subtenant) or to make any changes to the Subleased Premises because of the enactment of any law, ordinance, regulation, order or code during the Term. Notwithstanding anything in this Section to the contrary, Subtenant shall not be responsible for any repairs to the Subleased Premises made necessary by the acts of Tenant, Landlord, or their respective employees, officers, agents, servants, contractors, customers, clients, visitors, guests, or other licensees or invitees. 

   

  Upon expiration or earlier termination of the Term, Subtenant shall promptly and peacefully surrender the Subleased Premises to Tenant, together with all keys, in as good condition as when received by Subtenant or as thereafter improved (but subject to any obligations to remove any Subtenant’s Work and Alterations and/or to restore the same as provided elsewhere in this Sublease), reasonable wear and tear and insured casualty excepted.

  10.ACCESS AND RIGHT OF ENTRY. After reasonable written notice from Tenant (except in cases of emergency, where no notice is required) and subject to any and all rights of Landlord to enter the Premises under the Master Lease, Subtenant shall permit Tenant and/or Landlord and their respective agents, employees and contractors to enter the Subleased Premises at reasonable times to make repairs, alterations, improvements or inspections.

  a.Damage and Repair. If either Landlord or Tenant terminates the Master Lease as a result of condemnation of or casualty to the Subleased Premises, Master Premises, or Building or Property in accordance with the Master Lease, this Sublease shall terminate on the same date and in accordance therewith. If the Sublease is not terminated pursuant to the prior sentence and the Subleased Premises or the portion of the Building or Property reasonably necessary for Subtenant’s occupancy are damaged, destroyed or rendered untenantable, by fire or other casualty, Tenant may, at its option: (a) terminate this Sublease, or (b) restore (or cause Subtenant to restore) the Subleased Premises and the portion of the Building and Property reasonably necessary for Subtenant’s occupancy to the same or substantially similar condition that existed before the casualty event. Provided, however, if such casualty event occurs during the last six (6) months of the Term, then either Subtenant or Tenant may elect to terminate this Sublease. If, within 60 days after Tenant’s receipt of written notice from Subtenant that Subtenant deems the Subleased Premises or the portion of the Property reasonably necessary for Subtenant’s occupancy untenantable, Tenant fails to notify Subtenant of its election to restore those areas, or if Tenant is unable to restore those areas which Tenant is expressly required hereunder to restore within six (6) months of the date of the casualty event, then Subtenant may elect to terminate this Sublease by written notice given to Tenant at any time prior to the date on which Tenant substantially completes restoration of those areas which it is required hereunder to restore.

   

  If Tenant restores the Subleased Premises or the Property as provided under this Section, Tenant shall proceed with reasonable diligence to complete the work, and Base Rent shall be abated in the same proportion as the untenantable portion of the Subleased Premises bears to the whole Subleased Premises, provided that there shall be a Base Rent abatement only if the damage or destruction of the Subleased Premises or the Property did not result from, or was not contributed to directly or indirectly by, the act, fault or neglect of Subtenant or Subtenant’s employees, officers, agents, servants, contractors, customers, clients, visitors, guests, or other licensees or invitees. No damages, compensation or claim shall be payable by Tenant for Subtenant’s inconvenience, loss of business or annoyance directly, incidentally or consequentially arising from any repair or restoration of any portion of the Subleased Premises, Master Premises, Building, or Property. Tenant shall have no obligation to carry insurance of any kind for the protection of Subtenant or any Alterations or improvements paid for or installed by or on behalf of Subtenant; any Tenant’s Work or Subtenant’s Work identified in Exhibit 4 (regardless of who may have completed them); Subtenant’s furniture; or on any fixtures, equipment, improvements or appurtenances of Subtenant under this Sublease; and Tenant shall not be obligated to repair any damage thereto or replace the same unless the damage is caused by Tenant’s gross negligence or willful misconduct.

  b.Condemnation. If either Landlord or Tenant terminates the Master Lease based on any provision in the Master Lease relating to eminent domain or conveyance under threat of condemnation, this Sublease shall terminate on the same date and in accordance therewith. If the Sublease is not terminated pursuant to the prior sentence and the Subleased Premises, the portion of the Building or Property reasonably necessary for Subtenant’s occupancy, or 50% or more of the total rentable area of the Property are made untenantable by eminent domain, or conveyed under a threat of condemnation, this Sublease shall terminate at the option of each of Tenant and Subtenant as of the earlier of the date title vests in the condemning authority or the condemning authority first has possession of the portion of the Property taken by the condemning authority. All Rent and other payments required under this Sublease shall be paid to that date.

  If the condemning authority takes a portion of the Subleased Premises or the portion of the Property necessary for Subtenant’s occupancy that does not render them untenantable, then this Sublease shall continue in full force and effect and the Base Rent shall be equitably reduced based on the proportion by which the floor area of the Subleased Premises is reduced. The reduction in Base Rent shall be effective on the earlier of the date the condemning authority first has possession of such portion or title vests in the condemning authority. The Subleased Premises or the portion of the property reasonably necessary for Subtenant’s occupancy shall not be deemed untenantable if 25% or less of each of those areas is condemned. As between Tenant and Subtenant, Tenant shall be entitled to the entire award from the condemning authority attributable to the value of the Master Premises, Subleased Premises, or the Property or Building, and Subtenant shall make no claim for the value of its subleasehold estate or the Subtenant’s Work or any Alterations. Subtenant shall be permitted to make a separate claim against the condemning authority for moving expenses or damages resulting from interruption in its business if this Sublease is terminated under this Section, provided that in no event shall Subtenant’s claim reduce Landlord’s or Tenant’s awards.

  12.INSURANCE. Subtenant shall procure and maintain, at its sole cost and expense, such insurance as is required to be carried by Tenant under the Master Lease, and shall comply with all requirements with respect to the insurance of Tenant under the Master Lease, including, without limitation, obtaining additional insured endorsement(s) naming Tenant and Landlord as additional insureds, in the manner required therein, and property insurance as is required to be carried by Tenant under the Master Lease to the extent property insurance pertains to the Subleased Premises. If the Master Lease requires Tenant to insure leasehold improvements or Alterations, then Tenant shall insure the leasehold improvements which are located in the Subleased Premises, as well as the Tenant’s Work, and Subtenant shall insure any Alterations in the Subleased Premises performed by or on behalf of Subtenant. Subtenant shall furnish to Tenant certificates of Subtenant’s insurance policies and copies of any endorsements required hereunder not later than 10 days prior to Subtenant’s taking possession of the Subleased Premises. Tenant shall carry insurance as required by the Master Lease and shall not be obligated to carry property or liability insurance to the extent such insurance is an obligation of Landlord under the Master Lease.

   

  Tenant and Subtenant hereby release each other and their respective employees, officers, agents, servants, contractors, customers, clients, visitors, guests, or other licensees or invitees, from responsibility for and waive their respective claims for recovery of any loss or damage arising from any cause covered by insurance required to be carried by each of them. Each party shall provide notice to the insurance carrier or carriers of this mutual waiver of subrogation, and shall cause its respective insurance carriers to waive all rights of subrogation against the other. This waiver shall not apply to the extent of the deductible amounts to any such policies or to the extent of liability exceeding the limits of such policies. Tenant agrees to use reasonable efforts to obtain from Landlord for the benefit of Subtenant the same waiver of claims for any loss or damage arising from any cause covered by insurance required to be carried by Landlord under the Master Lease and, if and to the extent of such waiver received from Landlord, Subtenant agrees to grant the same waiver to Landlord.

   

  In no event shall Sublandlord be liable to Subtenant for business losses or consequential damages.  In no event shall Subtenant be liable to Sublandlord for business losses or consequential damages.

  13.ASSIGNMENT AND SUBLETTING. Subtenant shall not assign, sublet, mortgage, encumber or otherwise transfer any interest in this Sublease or any part of the Subleased Premises (collectively referred to as a “Transfer”), without first obtaining the written consent of Tenant, which shall not be unreasonably withheld, conditioned or delayed. Tenant may condition its consent on (a) obtaining any required consent from Landlord; (b) Subtenant satisfying any conditions to the Transfer imposed by Landlord and/or required to be satisfied by Tenant under the Master Lease; and (c) such other reasonable conditions that Tenant may impose. No Transfer shall relieve Subtenant of any liability under this Sublease notwithstanding Tenant’s consent to such Transfer. Consent to any Transfer shall not operate as a waiver of the necessity for Tenant’s consent to any subsequent Transfer. In connection with each request for consent to a Transfer, Subtenant shall pay the reasonable cost of processing same, including attorneys’ fees and any cost charged by Landlord for granting its consent under the Master Lease, upon demand of Tenant.

   

  Any transfer of this Sublease by merger, consolidation, redemption or liquidation of Subtenant, or any change in the ownership of, or power to vote, which singularly or collectively represents a majority of the beneficial interest in Subtenant, shall constitute a Transfer.

   

  As a condition to the Landlord’s and Tenant’s approval, if given, any potential assignee or sublessee otherwise approved shall assume all obligations of Subtenant under this Sublease and shall be jointly and severally liable with Subtenant and any guarantor for the payment of Rent and other charges due hereunder and performance of all obligations of Subtenant under this Sublease. In connection with any Transfer, Subtenant shall provide Landlord and Tenant with copies of all assignments, subleases and assumption agreements and related documents.

   

  14.MORTGAGE SUBORDINATION AND ATTORNMENT. This Sublease shall automatically be subordinate to any mortgage or deed of trust created by Landlord to the extent the Master Lease is subordinate to the same mortgage or deed of trust, and Subtenant shall attorn upon the same terms and conditions as the Tenant in the Master Lease, provided Subtenant shall enjoy the terms and conditions relating to such subordination and attornment to the same extent as Tenant under the terms of the Master Lease.

  15.HOLDOVER. If Subtenant shall, without the written consent of Tenant, remain in possession of the Subleased Premises and shall fail to return the Subleased Premises to Tenant after the expiration or termination of the Sublease, the tenancy shall be a holdover tenancy at sufferance, which may be terminated in accordance with Washington law; provided that, upon expiration of the Master Lease, such holdover tenancy by Subtenant shall automatically be deemed a tenancy at sufferance, terminable immediately.

   

  Unless Tenant agrees in writing to a different rental rate Subtenant agrees to pay to Tenant 150% of the rate of Base Rent last payable under this Sublease, during any holdover tenancy, in addition to all Additional Rent and other sums due under this Sublease. All other terms of the Sublease shall remain in effect. Nothing herein shall be deemed Tenant’s consent to holdover by Subtenant, or be deemed to permit Subtenant to remain in possession of the Subleased Premises on and after expiration of the Master Lease.

  16.NOTICES. All notices under this Sublease shall be in writing and effective (i) when delivered in person or via overnight courier to the other party, or (ii) three (3) days after being sent by registered or certified mail to the other party at the addresses set forth in Section 1. The addresses for notices and payment of Rent set forth in Section 1 may be modified by either party only by written notice delivered in conformance with this Section.

  17.ESTOPPEL CERTIFICATES. Upon the written request of Tenant, Subtenant shall execute and deliver to Tenant and/or Landlord or their designee a written estoppel certificate on the same terms and conditions as required of Tenant under the Master Lease.

  18.GENERAL.

  a.Heirs and Assigns. This Sublease shall apply to and be binding upon Tenant and Subtenant and their respective heirs, executors, administrators, successors and assigns.

  This Agency Disclosure creates an agency relationship between Subtenant, Subtenant’s Broker (if any such person is disclosed), and any managing brokers who supervise Subtenant’s Broker’s performance (collectively the “Supervising Brokers”). In addition, this Agency Disclosure creates an agency relationship between Tenant, Tenant’s Broker (if any such person is disclosed), and any managing brokers who supervise Tenant’s Broker’s performance (also collectively the “Supervising Brokers”). If Tenant’s Broker and Subtenant’s Broker are different real estate licensees affiliated with the same Firm, then both Tenant and Subtenant confirm their consent to that Firm and both Tenant’s and Subtenant’s Supervising Brokers acting as dual agents. If Tenant’s Broker and Subtenant’s Broker are the same real estate licensee who represents both parties, then both Subtenant and Tenant acknowledge that the Broker, his or her Supervising Brokers, and his or her Firm are acting as dual agents and hereby consent to such dual agency. If Tenant’s Broker, Subtenant’s Broker, their Supervising Brokers, or their Firm are dual agents, Subtenant and Tenant consent to Tenant’s Broker, Subtenant’s Broker, and their Firm being compensated based on a percentage of the rent or as otherwise disclosed on an attached addendum. Neither Tenant’s Broker, Subtenant’s Broker nor either of their Firms are receiving compensation from more than one party to this transaction unless otherwise disclosed on an attached addendum, in which case Subtenant and Tenant consent to such compensation. Subtenant and Tenant confirm receipt of the pamphlet entitled “The Law of Real Estate Agency.”

  Silverback Therapeutics, Inc. 
Award Agreement

  (2020 Equity Incentive Plan)

    

  As reflected by your RSU Award Grant Notice (“Grant Notice”), Silverback Therapeutics, Inc. (the “Company”) has granted you a RSU Award under the Company’s 2020 Equity Incentive Plan (the “Plan”) for the number of restricted stock units as indicated in your Grant Notice (the “RSU Award”).  The terms of your RSU Award as specified in this Award Agreement for your RSU Award (this “Agreement”) and the Grant Notice constitute your “RSU Award Agreement.”  Defined terms not explicitly defined in this Agreement but defined in the Grant Notice or the Plan shall have the same definitions as in the Grant Notice or Plan, as applicable.

  The general terms applicable to your RSU Award are as follows:

  1.Governing Plan Document.  Your RSU Award is subject to all the provisions of the Plan, including but not limited to the provisions in:

  a.Section 6 of the Plan regarding the impact of a Capitalization Adjustment, dissolution, liquidation, or Corporate Transaction on your RSU Award;

  b.Section 9(e) of the Plan regarding the Company’s retained rights to terminate your Continuous Service notwithstanding the grant of the RSU Award; and

  c.Section 8 of the Plan regarding the tax consequences of your RSU Award.

  Your RSU Award is further subject to all interpretations, amendments, rules and regulations, which may from time to time be promulgated and adopted pursuant to the Plan.  In the event of any conflict between the RSU Award Agreement and the provisions of the Plan, the provisions of the Plan shall control.

  2.Grant of the RSU Award.  This RSU Award represents your right to be issued on a future date the number of shares of the Company’s Common Stock that is equal to the number of restricted stock units indicated in the Grant Notice as modified to reflect any Capitalization Adjustment and subject to your satisfaction of the vesting conditions set forth therein (the “Restricted Stock Units”).  Any additional Restricted Stock Units that become subject to the RSU Award pursuant to Capitalization Adjustments as set forth in the Plan and the provisions of Section 3 below, if any, shall be subject, in a manner determined by the Board, to the same forfeiture restrictions, restrictions on transferability, and time and manner of delivery as applicable to the other Restricted Stock Units covered by your RSU Award.

  3.Dividends.  You shall receive no benefit or adjustment to your RSU Award with respect to any cash dividend, stock dividend or other distribution that does not result from a Capitalization Adjustment; provided, however, that this sentence will not apply with respect to any shares of Common Stock that are delivered to you in connection with your RSU Award after such shares have been delivered to you.

  4.Withholding Obligations.  As further provided in Section 8 of the Plan, you hereby authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for, any sums required to satisfy the federal, state, local and foreign tax withholding obligations, if any, which arise in connection with your RSU Award (the “Withholding Obligation”) in accordance with the withholding procedures established by the Company.  Unless the Withholding Obligation is satisfied, the Company shall have no obligation to deliver to you any Common Stock in respect of the RSU Award.  In the event the Withholding Obligation of the Company arises prior to the delivery to you of Common Stock or it is determined after the delivery of Common Stock to you that the amount of the Withholding Obligation was greater than the amount 

  

  withheld by the Company, you agree to indemnify and hold the Company harmless from any failure by the Company to withhold the proper amount.

  5.Date of Issuance.

  a.The issuance of shares in respect of the Restricted Stock Units is intended to comply with Treasury Regulations Section 1.409A-1(b)(4) and will be construed and administered in such a manner.  Subject to the satisfaction of the Withholding Obligation, if any, in the event one or more Restricted Stock Units vests, the Company shall issue to you one (1) share of Common Stock for each Restricted Stock Unit that vests on the applicable vesting date(s) (subject to any adjustment under Section 3 above, and subject to any different provisions in the Grant Notice).  Each issuance date determined by this paragraph is referred to as an “Original Issuance Date”.

  b.If the Original Issuance Date falls on a date that is not a business day, delivery shall instead occur on the next following business day. In addition, if:

  i.the Original Issuance Date does not occur (1) during an “open window period” applicable to you, as determined by the Company in accordance with the Company’s then-effective policy on trading in Company securities, or (2) on a date when you are otherwise permitted to sell shares of Common Stock on an established stock exchange or stock market (including but not limited to under a previously established written trading plan that meets the requirements of Rule 10b5-1 under the Exchange Act and was entered into in compliance with the Company’s policies (a “10b5-1 Arrangement”)), and

  ii.either (1) a Withholding Obligation does not apply or (2) the Company decides, prior to the Original Issuance Date, (A) not to satisfy the Withholding Obligation by withholding shares of Common Stock from the shares otherwise due, on the Original Issuance Date, to you under this RSU Award, and (B) not to permit you to enter into a “same day sale” commitment with a broker-dealer (including but not limited to a commitment under a 10b5-1 Arrangement) and (C) not to permit you to pay your Withholding Obligation in cash, then the shares that would otherwise be issued to you on the Original Issuance Date will not be delivered on such Original Issuance Date and will instead be delivered on the first business day when you are not prohibited from selling shares of the Company’s Common Stock in the open public market, but in no event later than December 31 of the calendar year in which the Original Issuance Date occurs (that is, the last day of your taxable year in which the Original Issuance Date occurs), or, if and only if permitted in a manner that complies with Treasury Regulations Section 1.409A-1(b)(4), no later than the date that is the 15th day of the third calendar month of the applicable year following the year in which the shares of Common Stock under this RSU Award are no longer subject to a “substantial risk of forfeiture” within the meaning of Treasury Regulations Section 1.409A-1(d).

  c.To the extent the RSU Award is a Non-Exempt RSU Award, the provisions of Section 11 of the Plan shall apply.

  6.Transferability. Except as otherwise provided in the Plan, your RSU Award is not transferable, except by will or by the applicable laws of descent and distribution.

  7.Corporate Transaction.  Your RSU Award is subject to the terms of any agreement governing a Corporate Transaction involving the Company, including, without limitation, a provision for the appointment of a stockholder representative that is authorized to act on your behalf with respect to any escrow, indemnities and any contingent consideration.

  8.No Liability For Taxes.  As a condition to accepting the RSU Award, you hereby (a) agree to not make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates related to tax liabilities arising from the RSU Award or other Company compensation and (b) acknowledge that you were advised to consult with your own personal tax, financial and other legal 

  

  advisors regarding the tax consequences of the RSU Award and have either done so or knowingly and voluntarily declined to do so.

  9.Severability.  If any part of this Agreement or the Plan is declared by any court or governmental authority to be unlawful or invalid, such unlawfulness or invalidity will not invalidate any portion of this Agreement or the Plan not declared to be unlawful or invalid.  Any Section of this Agreement (or part of such a Section) so declared to be unlawful or invalid will, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid.

  10.Other Documents.  You hereby acknowledge receipt of or the right to receive a document providing the information required by Rule 428(b)(1) promulgated under the Securities Act, which includes the Prospectus.  In addition, you acknowledge receipt of the Company’s Trading Policy.

  11.Questions.  If you have questions regarding these or any other terms and conditions applicable to your RSU Award, including a summary of the applicable federal income tax consequences please see the Prospectus.
