On or before the Commencement Date and with each Landlord’s Statement (defined in Article 4), Landlord may estimate and notify Tenant in writing of its estimate of Tenant’s Share of the Operating Expenses and of Taxes for such calendar year (or partial calendar year). Prior to the first determination by Landlord of the amount of Operating Expenses and of Taxes for the first calendar year (or partial calendar year), Landlord may estimate such amounts in the foregoing calculation. Landlord shall have the right from time to time during any calendar year to provide a new or revised estimate of Operating Expenses and/or Taxes and to notify Tenant in writing thereof, of corresponding adjustments in Tenant’s Rent Adjustment Deposit payable over the remainder of such year, and of the amount or revised amount due allocable to months preceding such change. The last estimate by Landlord shall remain in effect as the applicable Rent Adjustment Deposit unless and until Landlord notifies Tenant in writing of a change, which notice may be given by Landlord from time to time during each year throughout the Term.

STANDARD OPERATING HOURS: Monday through Friday from 8:00 A.M. to 6:00 P.M. and Saturdays from 9:00 A.M. to 1:00 P.M., excluding National Holidays.

SUBSTANTIALLY COMPLETE or SUBSTANTIAL COMPLETION: The completion of the Landlord Work in good and workmanlike manner, in material compliance with all applicable Laws and the plans and specifications, except for minor insubstantial details of construction, decoration or mechanical adjustments which remain to be done which do not materially and substantially interfere with Tenant’s construction of the Tenant Work in the Premises. Substantial Completion shall be deemed to have occurred notwithstanding a requirement to complete “punchlist” or similar minor corrective work.

TAXES: All federal, state and local governmental taxes, assessments, license fees and charges of every kind or nature, whether general, special, ordinary or extraordinary, which Landlord shall pay or become obligated to pay because of or in connection with the ownership, leasing, management, control, sale, transfer or operation of the Property or any of its components (including any personal property used in connection therewith) or Landlord’s business of owning and operating the Property, which may also include any rental, revenue, general gross receipts or similar taxes levied in lieu of or in addition to general real and/or personal property taxes. For purposes hereof, Taxes for any year shall be Taxes which are assessed for any period of such year, whether or not such Taxes are billed and payable in a subsequent calendar year. There shall be included in Taxes for any year the amount of all fees, costs and expenses (including reasonable attorneys’ fees) paid by Landlord during such year in seeking or obtaining any refund or reduction of Taxes. Taxes for any year shall be reduced by the net amount of any tax refund received by Landlord attributable to such year. If a special assessment payable in installments is levied against any part of the Property, Taxes for any year shall include only the installment of such assessment and any interest payable or paid during such year. Taxes shall not include any federal or state inheritance, general income, transfer, gift or estate taxes, except that if a change occurs in the method of taxation resulting in whole or in part in the substitution of any such taxes, or any other assessment, for any Taxes as above defined, such substituted taxes or assessments shall be included in the Taxes. Tenant and Landlord acknowledge that Proposition 13 was adopted by the voters of the State of California in the June, 1978 election and that assessments, taxes, fees, levies and charges may be imposed by governmental agencies for such purposes as fire protection, street, sidewalk, road, utility construction and maintenance, refuse removal and for other governmental services which may formerly have been provided without charge to property owners or occupants. It is the intention of the parties that all new and increased assessments, taxes, fees, levies and charges due to any cause whatsoever are to be included within the definition of real property taxes for purposes of this Lease.

TENANT WORK: All work installed or furnished to the Premises by Tenant in accordance with the Workletter.

TENANT’S SHARE: The percentage that represents the ratio of the Rentable Area of the Premises to the Rentable Area of the Building, as determined by Landlord from time to time, and which as of the Date of Lease is 28.94%. Tenant acknowledges that the Rentable Area of the Premises or Building may change from re-measurement or otherwise during the Term, or as a result of Tenant leasing additional space within the Building or a physical change to the size of the

Premises or Building (provided, however, that, the Base Rent payable hereunder shall not be changed as a consequence of a re-measurement of the Building and/or the Premises unless the Premises are physically expanded). Notwithstanding anything herein to the contrary, Landlord may equitably adjust Tenant’s Share for all or part of any item of expense or cost reimbursable by Tenant that relates to a repair, replacement, or service that benefits only the Premises or only a portion of the Building and/or the Project or that varies with the occupancy of the Building and/or the Project, provided such adjustment is done in accordance with sound real estate accounting and management principles, consistently applied.

TERM: The initial term of this Lease commencing on the Commencement Date and expiring on the Expiration Date, including the Renewal Term, if Tenant properly exercises the Renewal Option in accordance with Section 2.6.

TERMINATION DATE: The Expiration Date or such earlier date as this Lease terminates or Tenant’s right to possession of the Premises terminates.

WORKLETTER: The Agreement regarding the manner of completion of Landlord Work and Tenant Work set forth on Exhibit B attached hereto.

(a)Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, the Premises for the Term and upon the terms, covenants and conditions provided in this Lease.

(b)The parties acknowledge and agree that the Rentable Area set forth in this Lease has been conclusively determined and is deemed final for the purposes of this Lease and that prior to the Date of Lease, Tenant had the right to cause its Architect to verify and confirm the Rentable Area of the Premises.

(a)The Commencement Date shall be the date which Landlord delivers possession of the Premises to Tenant with the Landlord Work Substantially Complete to allow Tenant to commence construction of the Tenant Work.

(b)Within thirty (30) days following the Rent Commencement Date, Landlord and Tenant shall enter into an agreement (the form of which is attached hereto as Rider 1) confirming the Rent Commencement Date and the Expiration Date. If Tenant fails to enter into such agreement, then the Rent Commencement Date and the Expiration Date shall be the date designated by Landlord in such agreement.

Landlord shall use commercially reasonable efforts to tender possession of the Premises to Tenant by the later of the Date of Lease or the Projected Commencement Date with the Landlord Work Substantially Complete. Tenant agrees that if Landlord shall be unable to tender possession of the Premises with the Landlord Work Substantially Complete by the Projected Commencement Date for any reason, then this Lease shall not be void or voidable, nor shall Landlord be subject to any liability therefor. Landlord and Tenant hereby acknowledge and agree that Tenant’s access/entry to the Premises prior to Rent Commencement Date shall be subject to all the provisions of this Lease (including payment of any utilities used in the Premises) other than the payment of Monthly Base Rent and Tenant’s Share of Operating Expenses, including, without limitation, Tenant’s compliance with the insurance and indemnity requirements of this Lease. In connection with any such early entry, Tenant agrees that it shall not in any way unreasonably interfere with the progress of any other work being conducted in the Building, either by Landlord and/or Landlord’s tenants. Should such early entry unreasonably interfere with the progress of other work, in Landlord’s reasonable judgment, then Landlord may demand that Tenant forthwith cease the activities that are causing such interference or vacate the Premises as necessary until such interference would not occur, and Tenant shall immediately comply with such demand.

Landlord represents and warrants that, as of the Commencement Date, the Building’s structural components and electrical and plumbing systems, including, without limitation, heating, ventilation and air-conditioning (collectively, “Building Systems”), are in good condition and repair. No later than one hundred twenty (120) days after the Commencement Date, Tenant shall notify Landlord in writing of any defects in the Landlord Work and/or the Building Systems (other than defects caused by Tenant after the Commencement Date) that are claimed by Tenant or in the materials or workmanship furnished by Landlord in completing the Landlord Work. Except for defects stated in such notices, Tenant shall be conclusively deemed to have accepted the Premises “AS IS” in the condition existing on the Commencement Date. Landlord shall proceed diligently to correct the defects stated in such notices unless Landlord disputes in good faith the existence of any such defects. In the event of any dispute as to the existence of any such defects, the reasonable and good faith decision of Landlord’s architect shall be final and binding on the parties. No agreement of Landlord to alter, remodel, decorate, clean or improve the Premises or the Real Property and no representation regarding the condition of the Premises or the Real Property has been made by or on behalf of Landlord to Tenant, except as may be specifically stated in this Lease or in the Workletter.

During the Term, Tenant shall have the right to park up to one hundred fifty-one (151) cars of Tenant and its employees (“Tenant’s Parking”), such quantity calculated to be two (2) vehicle rights for every one thousand (1,000) rentable square feet of Premises. Subject to the aforementioned maximum, Tenant shall have the right to set the number of Tenant’s Parking as of the Commencement Date and thereafter to adjust the amount of Tenant’s Parking not more often than monthly upon thirty (30) days’ advance written notice to Landlord. Initially, Tenant’s Parking shall be located in the Garage owned by Landlord and located at 6100 Horton Street and shall be leased by Tenant at then quoted rates. In the event Tenant fails at any time to pay the full amount of any such parking charges beyond all applicable notice and cure periods, then Tenant’s parking

rights shall be reduced to the extent of Tenant’s failure to pay for any such parking, and Tenant shall be in Default hereunder. The locations and type of parking shall be designated by Landlord or Landlord’s parking operator from time to time; provided, however, that any portion of Tenant’s Parking that is not provided in the garage shall be located at other location(s) in the vicinity of the Project. Tenant acknowledges and agrees that the parking stalls serving the Project may include valet parking and a mixture of stalls for compact vehicles as well as full‑size passenger automobiles, and that Tenant shall not use parking stalls for vehicles larger than the striped size of the parking stalls nor shall Tenant park cars overnight. All vehicles utilizing Tenant’s parking privileges shall prominently display identification stickers or other markers, and/or have passes or keycards for ingress and egress, as may be required and provided by Landlord or its parking operator from time to time. To the extent provided to Tenant in writing, Tenant shall comply with any and all non-discriminatory parking rules and regulations from time to time established by Landlord or Landlord’s parking operator, including a requirement that Tenant pay to Landlord or Landlord’s parking operator a charge for loss and replacement of passes, keycards, identification stickers or markers, and for any and all loss or other damage caused by persons or vehicles related to use of Tenant’s parking privileges. Tenant shall not allow any vehicles using Tenant’s parking privileges to be parked, loaded or unloaded except in accordance with this Section, including in the areas and in the manner reasonably designated by Landlord or its parking operator for such activities. If any vehicle is using the parking or loading areas contrary to any provision of this Section, Landlord or its parking operator shall have the right, in addition to all other rights and remedies of Landlord under this Lease, to remove or tow away the vehicle without prior notice to Tenant, and the cost thereof shall be paid to Landlord within ten (10) days after notice from Landlord to Tenant.

(a)Tenant shall have the option to renew this Lease (“Renewal Option”) with respect to the entirety of the Premises for two (2) consecutive additional terms of five (5) years each (each a “Renewal Term”), commencing upon expiration of the initial Term or the first Renewal Term, as applicable. Each Renewal Option must be exercised, if at all, by written notice given by Tenant to Landlord not earlier than eighteen (18) months and not later than twelve (12) months prior to commencement of the Renewal Term. If Tenant properly exercises a Renewal Option, then references in this Lease to the Term shall be deemed to include the Renewal Term. Tenant’s rights under this Section 2.6 shall, at the option of Landlord, be null and void and Tenant shall have no right to renew this Lease if on the date Tenant exercises a Renewal Option or on the date immediately preceding the commencement date of a Renewal Term a Default beyond the applicable notice and cure period shall have occurred and be continuing hereunder; provided, however, if Tenant cures such Default within the applicable periods provided under this Lease, then the Renewal Option shall be reinstated.

(b)If Tenant properly exercises a Renewal Option, then during such Renewal Term all of the terms and conditions set forth in this Lease as applicable to the Premises during the initial Term shall apply during the Renewal Term, including, without limitation, the obligation to pay Rent Adjustments, except that (i) Tenant shall accept the Premises in their then “as-is” state and condition, and Landlord shall have no obligation to make or pay for any improvements to the Premises, and (ii) during the Renewal Term the Monthly Base Rent payable by Tenant shall be the Fair Market Value during the Renewal Term as hereinafter set forth, except that in no event shall Monthly Base Rent during a Renewal Term be less than one hundred percent (100%) of the Monthly Base Rent in effect during the month immediately preceding the Renewal Term.

(c)For purposes of this Section, the term “Fair Market Value” shall mean the base rental rate, including periodic rent adjustment, for space comparable in size, location and quality of the Premises under primary lease (and not sublease) to new or renewing tenants, for a comparable term with base rent adjusted for the relative tenant improvement allowance, if applicable, and taking into consideration such amenities as existing improvements and non-removable fixtures in place at the time of such renewal (but not including the value of any Tenant Alterations made to the Premises following the Rent Commencement Date and the completion of Tenant’s initial build-out), view, floor on which the Premises is situated and the like, situated in comparable science/laboratory buildings in Emeryville and Berkeley.

(d)If Tenant properly exercises a Renewal Option, then Landlord, by notice to Tenant not later than six (6) months prior to commencement of the Renewal Term, shall indicate Landlord’s determination of the Fair Market Value. Tenant, within fifteen (15) days after the date on which Landlord provides such notice of the Fair Market Value shall either (i) give Landlord final binding written notice (“Binding Notice”) of Tenant’s acceptance of Landlord’s determination of the Fair Market Value, or (ii) if Tenant disagrees with Landlords’ determination, provide Landlord with written notice of Tenant’s election to submit the Fair Market Value to binding arbitration (the “Arbitration Notice”). If Tenant fails to provide Landlord with either a Binding Notice or Arbitration Notice within such fifteen (15) day period, Landlord shall send Tenant a second written notice specifying the Fair Market Rent (“Second FMV Notice”), and such Second FMV Notice shall include the following: “FAILURE TO ACCEPT SAID FAIR MARKET RENT AMOUNT IN WRITING OR DISPUTE SUCH AMOUNT BY SUBMITTING TO ARBITRATION IN ACCORDANCE WITH SECTION 2.6(d) OF THIS LEASE WITHIN TEN (10) DAYS SHALL BE DEEMED TENANT’S AGREEMENT TO PAY SUCH AMOUNT DURING THE RENEWAL TERM.” If Tenant fails to provide Landlord with either a Binding Notice or Arbitration Notice within ten (10) days after receiving the Second FMV Notice, Tenant shall have been deemed to have given the Binding Notice. If Tenant provides or is deemed to have provided Landlord with a Binding Notice, Landlord and Tenant shall enter into the Renewal Amendment (as defined below) upon the terms and conditions set forth herein.

(e)If the parties are unable to agree upon the Fair Market Value for the Premises within ten (10) business days after Landlord’s receipt of the Arbitration Notice, Fair Market Value as of commencement of the Renewal Term shall be determined as follows:

(1)Within thirty (30) days after the date Tenant delivers the Arbitration Notice, Tenant, at its sole expense, shall obtain and deliver in writing to Landlord a determination of the Fair Market Value for the Premises for a term equal to the Renewal Term from an independent broker or appraiser (“Tenant’s broker”) licensed in the State of California and engaged in the science/laboratory markets in Emeryville and Berkeley, California, for at least the immediately preceding five (5) years who has not been engaged by either Landlord or Tenant in the last five (5) years. If Landlord accepts such determination, Landlord shall provide written notice thereof within ten (10) days after Landlord’s receipt of such determination and the Base Rent for the Renewal Term shall be adjusted to an amount equal to the Fair Market Value determined by Tenant’s broker. Landlord shall be deemed to have rejected Tenant’s determination if Landlord fails to respond within the ten (10) day period.

(2)If Landlord provides notice that it rejects, or is deemed to have rejected, such determination, within twenty (20) days after receipt of the determination of Tenant’s broker, Landlord shall designate a broker or appraiser (“Landlord’s broker”) licensed in the State of California and possessing the qualifications set forth in (1) above. Landlord’s broker and Tenant’s broker shall name a third broker, similarly qualified, within five (5) days after the appointment of Landlord’s broker (“Neutral Broker”).

(3)The Neutral Broker shall determine the Fair Market Value for the Premises as of the commencement of the Renewal Term within fifteen (15) days after the appointment of such Neutral Broker by choosing the determination of the Landlord’s broker that was set forth in the initial notice delivered by Landlord pursuant to Section 2.6(d) or the Tenant’s broker that was delivered pursuant to Section 2.6(e)(1) which is closest to its own determination of Fair Market Value. The decision of the Neutral Broker shall be binding on Landlord and Tenant.

(f)Landlord shall pay the costs and fees of Landlord’s broker in connection with any determination hereunder, and Tenant shall pay the costs and fees of Tenant’s broker in connection with such determination. The costs and fees of the Neutral Broker shall be paid one-half by Landlord and one-half by Tenant. Landlord shall have no obligation to pay a fee or commission to any broker retained by Tenant in connection with Tenant’s exercise of a Renewal Option.

(g)If the amount of the Fair Market Value has not been determined pursuant to this Section 2.6 as of the commencement of the Renewal Term, then Tenant shall continue to pay the Base Rent in effect during the last month of the initial Term until the amount of the Fair Market Value is determined. When such determination is made, Tenant shall pay any deficiency to Landlord upon demand.

(h)If Tenant is entitled to and properly exercises its Renewal Option, upon determination of Fair Market Value pursuant to this Section 2.6, Landlord shall prepare an amendment (the “Renewal Amendment”) to reflect changes in the Base Rent, Term, Expiration Date and other appropriate terms. The Renewal Amendment shall be sent to Tenant within a reasonable time after determination of Fair Market Value and, provided the same is accurate, Tenant shall execute and return the Renewal Amendment to Landlord within ten (10) days after Tenant’s receipt of same, but an otherwise valid exercise of the Renewal Option shall be fully effective whether or not the Renewal Amendment is executed.

Subject to the rights of other parties existing as of the Date of Lease (“Superior Rights”) as set forth in Schedule 1 attached hereto, commencing upon the Rent Commencement Date and continuing throughout the Term (including the Renewal Term), Tenant shall have the right of first offer (“Right of First Offer”, or “ROFO”) with respect to no more than one (1) adjacent full floor in the Building which becomes Available for Lease (described below) (the “Offering Space”). Landlord represents and warrants that all Superior Rights are set forth in Schedule 1 attached hereto and incorporated herein. For the avoidance of doubt, Landlord shall have the right to lease any space in the Building at any time prior to the Rent Commencement Date on such terms as Landlord may determine in its sole and absolute discretion regardless of whether such space would otherwise qualify as Special Offering Space if it were Available for Lease as of the Rent Commencement Date. Offering Space shall be deemed to be “Available for Lease” as follows: (i) with respect to any Offering Space that has been leased to a third party tenant prior to the Rent Commencement Date hereunder or that at any time and from time to time thereafter is under lease to a third party tenant, such Offering Space shall be deemed to be Available for Lease when

Landlord has determined that such third party will not extend or renew the term of its lease for the Offering Space (whether or not pursuant to the terms of a renewal option provided for in its lease), no occupant has a Superior Right which is subject to exercise and Landlord is ready to market such space for lease, or (ii) with respect to any Offering Space that is not under lease, such Offering Space shall be deemed to be Available for Lease when Landlord has determined that no occupant has a Superior Right which is subject to exercise and Landlord is ready to market such space for lease. After Landlord has determined that any portion of Offering Space is Available for Lease, Landlord shall advise Tenant (the “ROFO Notice”) of the terms under which Landlord is prepared to lease such portion of the Offering Space to Tenant, including, without limitation, description of the space so offered to Tenant and material economic terms and conditions applicable to Tenant’s lease of such space (collectively, “First Offer Economic Terms”). Tenant may lease such Offering Space in its entirety only, under such First Offer Economic Terms, by delivering written notice of exercise to Landlord (“ROFO Notice of Exercise”) within fifteen (15) days after the date of delivery of the ROFO Notice, except that Tenant shall have no such Right of First Offer and Landlord need not provide Tenant with a ROFO Notice, if: (i) Tenant is in Default under this Lease at the time Landlord would otherwise deliver the ROFO Notice; or (ii) the Premises, or any portion thereof, is sublet (other than pursuant to a Permitted Transfer) at the time Landlord would otherwise deliver the ROFO Notice; or (iii) this Lease has been assigned (other than pursuant to a Permitted Transfer) prior to the date Landlord would otherwise deliver the ROFO Notice; or (iv) either Tenant or Permitted Transferee is not occupying at least fifty percent (50%) of the Premises on the date Landlord would otherwise deliver the ROFO Notice. If Tenant does not accept a ROFO Notice from Landlord pursuant to the above, then Landlord shall have the right to lease all or any portion of the Offering Space to any third party or parties upon such terms as Landlord and such tenant(s) may approve, in their respective sole and absolute discretion.

(a)Terms. The term for the Offering Space shall commence upon the commencement date stated in the ROFO Notice and thereupon such Offering Space shall be considered a part of the Premises, provided that all of the First Offer Economic Terms stated in the ROFO Notice shall govern Tenant’s leasing of the Offering Space and only to the extent that they do not conflict with the ROFO Notice, the terms and conditions of this Lease shall apply to the Offering Space.

(b)Limitation on Right of First Offer. The rights of Tenant hereunder with respect to any portion of the Offering Space shall terminate on the earlier to occur of: (i) with respect to any portion of the Offering Space that is the subject of a ROFO Notice, Tenant’s failure to exercise its Right of First Offer within the fifteen (15) day period provided in Section 2.7(a) above, and (ii) with respect to any portion of the Offering Space which would otherwise have been the subject of a ROFO Notice, the date Landlord would have provided Tenant a ROFO Notice if Tenant had not been in violation of one or more of the conditions set forth in clauses (i) through (iv) of Section 2.7(a) above. In addition, at any time that Tenant has expanded its Premises beyond 150% of the size set forth in Section 1.1(11) hereof pursuant to the above ROFO process or otherwise, Tenant shall have no further ROFO rights hereunder.

(c)Offering Amendment. If Tenant exercises its Right of First Offer, Landlord shall prepare an amendment (the “Offering Amendment”) adding the Offering Space to the Premises on the First Offer Economic Terms and reflecting the changes in the Monthly Base Rent, Rentable Area of the Premises, Tenant’s Share, Rent Adjustments and other appropriate terms. A copy of the Offering Amendment shall be (i) sent to Tenant within a reasonable time after receipt of the

ROFO Notice of Exercise executed by Tenant, and (ii) executed by Tenant and returned to Landlord within fifteen (15) days thereafter, but an otherwise valid exercise of the Right of First Offer shall be fully effective whether or not the Offering Amendment is signed.

(a)In the Building: Subject to the superior rights of other parties existing as of the date of this Lease (“Special Superior Rights”) as set forth in Schedule 2 attached hereto, for the period commencing January 1, 2020 and ending March 31, 2021 (the “Special ROFO Period”), Tenant shall have the right of first offer (the “Special ROFO”) with respect to any suite in the Building measuring no less than twelve thousand (12,000) rentable square feet nor more than twenty-thousand (20,000) rentable square feet that becomes Available for Lease (described below) (the “Special Offering Space”). Landlord represents and warrants that all Special Superior Rights are set forth in Schedule 2 attached hereto and incorporated herein. For the avoidance of doubt, Landlord shall have the right to lease any space in the Building at any time prior to the commencement of the Special ROFO Period Special on such terms as Landlord may determine in its sole and absolute discretion regardless of whether such space might otherwise qualify as Special Offering Space if it were Available for Lease as of the first day of the Special ROFO Period. Special Offering Space shall be deemed to be “Available for Lease” as follows: (i) with respect to any Special Offering Space that has been leased to a third party tenant prior to the commencement of the Special ROFO Period (or if Landlord has entered into a letter of intent with a prospective third party for the lease of any such space prior to the commencement of the Special ROFO Period), such Special Offering Space shall be deemed to be Available for Lease when Landlord has determined that such third party (i.e., one who has entered into a lease prior to the Special ROFO Period or who has entered into a lease that was the subject of a letter of intent entered into prior to the commencement of the Special ROFO Period) will not extend or renew the term of its lease for the Special Offering Space (whether or not pursuant to the terms of a renewal option provided for in its lease), no occupant has a Special Superior Right which is subject to exercise and Landlord is ready to market such space for lease, or (ii) with respect to any Special Offering Space that is not under lease prior to the commencement of the Special ROFO Period, such Special Offering Space shall be deemed to be Available for Lease when Landlord has determined that no occupant has a Special Superior Right which is subject to exercise and Landlord is ready to market such space for lease. If during the Special ROFO Period, Landlord has determined that any Special Offering Space is Available for Lease, Landlord shall advise Tenant (the “Special ROFO Notice”) of the terms under which Landlord is prepared to lease such Special Offering Space to Tenant, including, without limitation, description of the space so offered to Tenant and material economic terms and conditions applicable to Tenant’s lease of such space (collectively, “Special ROFO Economic Terms”). Tenant may lease such Special Offering Space in its entirety only, under such Special ROFO Economic Terms, by delivering written notice of exercise to Landlord (“Special ROFO Notice of Exercise”) within fifteen (15) days after the date of delivery of the Special ROFO Notice, except that Tenant shall have no such Special Right of First Offer and Landlord need not provide Tenant with a Special ROFO Notice, if: (i) Tenant is in Default under this Lease at the time Landlord would otherwise deliver the Special ROFO Notice; or (ii) the Premises, or any portion thereof, is sublet (other than pursuant to a Permitted Transfer) at the time Landlord would otherwise deliver the Special ROFO Notice; or (iii) this Lease has been assigned (other than

pursuant to a Permitted Transfer) prior to the date Landlord would otherwise deliver the Special ROFO Notice; or (iv) either Tenant or Permitted Transferee is not occupying all of the Premises on the date Landlord would otherwise deliver the Special ROFO Notice. If Tenant does not accept a Special ROFO Notice from Landlord pursuant to the above, then Landlord shall have the right to lease all or any portion of the Special Offering Space to any third party or parties upon such terms as Landlord and such tenant(s) may approve, in their respective sole and absolute discretion.

(i)Terms. The term for the Special Offering Space shall commence upon the commencement date stated in the Special ROFO Notice and thereupon such Special Offering Space shall be considered a part of the Premises, provided that all of the Special ROFO Economic Terms stated in the Special ROFO Notice shall govern Tenant’s leasing of the Special Offering Space and only to the extent that they do not conflict with the Special ROFO Notice, the terms and conditions of this Lease shall apply to the Special Offering Space.

(ii)Limitation on Special Right of First Offer. The rights of Tenant hereunder with respect to any Special Offering Space shall terminate on the earlier to occur of: (i) with respect to any Special Offering Space that is the subject of a Special ROFO Notice, Tenant’s failure to exercise its Special Right of First Offer within the fifteen (15) day period provided in Section 2.8(a) above, (ii) with respect to any Special Offering Space which would otherwise have been the subject of a Special ROFO Notice, the date Landlord would have provided Tenant a Special ROFO Notice if Tenant had not been in violation of one or more of the conditions set forth in clauses (i) and (iv) of Section 2.8(a) above, or (iii) the expiration of the Special ROFO Period. In addition, at any time that Tenant has expanded its Premises beyond the 150% of the size set forth in Section 1.1(11) hereof, or to an additional floor, pursuant to the above ROFO process outlined in Section 2.7 above or otherwise, Tenant shall have no further Special ROFO rights hereunder.

(iii)Offering Amendment. If Tenant exercises its Special Right of First Offer, Landlord shall prepare an amendment (the “Offering Amendment”) adding the Special Offering Space to the Premises on the Special ROFO Economic Terms and reflecting the changes in the Monthly Base Rent, Rentable Area of the Premises, Tenant’s Share, Rent Adjustments and other appropriate terms. A copy of the Offering Amendment shall be (i) sent to Tenant within a reasonable time after receipt of the Special ROFO Notice of Exercise executed by Tenant, and (ii) executed by Tenant and returned to Landlord within fifteen (15) days thereafter, but an otherwise valid exercise of the Special Right of First Offer shall be fully effective whether or not the Offering Amendment is signed.

(b)In Property Owned By Landlord Affiliates: During the Special ROFO Period, but only if (i) Landlord has not previously offered Offering Space to Tenant pursuant to Section 2.7, or Special Offering Space to Tenant pursuant to Section 2.8(a), or (ii) a Landlord Affiliate has not previously offered Affiliate Offering Space to Tenant pursuant to this Section 2.8(b), Tenant may request in writing (a “Tenant Affiliate Offering Space Request”) that Landlord use commercially-reasonable efforts to cause a Landlord Affiliate that owns office and/or lab property in Emeryville, California (if any, an “Emeryville Affiliate to provide Tenant with an offer (“Affiliate Offer Right”) to lease to Tenant any space owned by such an Emeryville Affiliate which measures no less than twelve thousand (12,000) rentable square feet nor more than twenty-thousand (20,000) rentable square feet and is then Available for Lease (described below) (the “Affiliate Offering

Space”). Tenant’s rights hereunder shall be subject to the superior rights of other parties (an “Affiliate Offer Superior Rights”) in any respective Emeryville Affiliate’s property or properties, which superior right(s) may be granted by any Emeryville Affiliate at any time and from time to time. For the avoidance of doubt, any Emeryville Affiliate shall have the right shall have the right to lease any space in a property it owns at any time on such terms as such Emeryville Affiliate may determine in its sole and absolute discretion regardless of whether such space might otherwise qualify as Affiliate Offering Space if it were Available for Lease at the time that Tenant delivers a Tenant Affiliate Offering Space Request. An Affiliate Offering Space shall be deemed to be “Available for Lease” if, at the time that Tenant delivers a Tenant Affiliate Offering Space Request, (i) such space is not then under lease to a third party and the Emeryville Affiliate in question is not then in negotiations with a third party for the lease thereof, (ii) no third party has an Affiliate Offer Superior Right which is subject to exercise, and (iii) the respective Emeryville Affiliate is ready to market such space for lease. If at the time Tenant delivers a Tenant Affiliate Offering Space Request, Landlord determines that an Emeryville Affiliate has Affiliate Offering Space that is Available for Lease, said Emeryville Affiliate may advise Tenant (the “Affiliate Offer Notice”) of the terms under which said Emeryville Affiliate may be prepared to lease such Affiliate Offering Space to Tenant, including, without limitation, description of the space so offered to Tenant and proposed material economic terms and conditions applicable to Tenant’s lease of such space (collectively, “Affiliate Offer Economic Terms”). Tenant may lease such Affiliate Offering Space in its entirety only, under such Affiliate Offer Economic Terms, by delivering written notice of exercise to the appropriate Emeryville Affiliate (“Affiliate Offer Notice of Exercise”) within fifteen (15) days after the date of delivery of the Affiliate Offer Notice, except that Tenant shall have no such Affiliate Offer Right and an Emeryville Affiliate need not provide Tenant with an Affiliate Offer Notice, if: (i) Tenant is in Default under this Lease at the time the Emeryville Affiliate would otherwise deliver the Affiliate Offer Notice; or (ii) the Premises, or any portion thereof, is sublet (other than pursuant to a Permitted Transfer) at the time the Emeryville Affiliate would otherwise deliver the Affiliate Offer Notice; (iii) this Lease has been assigned (other than pursuant to a Permitted Transfer) prior to the date the Emeryville Affiliate would otherwise deliver the Affiliate Offer Notice; or (iv) either Tenant or Permitted Transferee is not occupying all of the Premises on the date the Emeryville Affiliate would otherwise deliver the Affiliate Offer Notice.

(i)Terms. The term for any Affiliate Offering Space shall commence upon the commencement date stated in the Affiliate Offer Notice. Tenant understands and acknowledges that the terms of any accepted Affiliate Offer Notice would require documentation in a new lease between said Emeryville Affiliate and Tenant, the terms of which lease, other than the Affiliate Offer Economic Terms, must be approved by both the Emeryville Affiliate and Tenant in their respective sole and absolute discretions.

(ii)Limitation on Affiliate Offer Right. The Affiliate Offer Right is a one-time only right; and if Tenant does not accept an Affiliate Offer Notice from an Emeryville Affiliate within the fifteen (15) day period provided in Section 2.8(b) above, such right shall terminate. Further, the Affiliate Offer Right shall terminate if and at such time as Landlord is able to offer either Offering Space or Special Offering Space to Tenant pursuant to process outlined in Section 2.7 or 2.8(a) above prior to the expiration of the Special ROFO Period, whether or not Tenant accepts any such offer from Landlord. The Affiliate Offer Right shall also terminate upon the expiration of the Special ROFO Period.

Tenant specifically understands and agrees that, while Landlord has agreed to use its commercially-reasonable efforts to cause an Emeryville Affiliate to follow the Affiliate Offer process outlined above, Landlord’s inability or failure to do so shall not constitute a Default under this Lease, and that Tenant shall have no remedy nor cause of action either against Landlord or against any Emeryville Affiliate for such failure or inability on the part of Landlord nor for the failure of any Emeryville Affiliate to make any Affiliate Offer Notice to Tenant or of any Emeryville Affiliate to conclude a lease with Tenant pursuant to terms contained in any Affiliate Offer Notice that Tenant may have accepted via Affiliate Offer Notice of Exercise.

Tenant shall pay to Landlord at the address specified in Section 1.1(2), or to such other persons, or at such other places designated by Landlord or by electronic funds transfer pursuant to Landlord’s written instructions, without any prior demand therefor in immediately available funds and without any deduction or offset whatsoever, Rent, including Monthly Base Rent and Rent Adjustments in accordance with Article 4, during the Term. Monthly Base Rent shall be paid monthly in advance on the first day of each month of the Term, except that the first installment of Monthly Base Rent shall be paid by Tenant to Landlord concurrently with execution of this Lease. Monthly Base Rent shall be prorated for partial months within the Term. Unpaid Rent shall bear interest at the Default Rate from the date Tenant receives a notice of such default due until paid. Tenant’s covenant to pay Rent shall be independent of every other covenant in this Lease.

From and after the Commencement Date, Tenant shall pay to Landlord Rent Adjustments with respect to each calendar year (or partial calendar year in the case of the year in which the Commencement Date and the Termination Date occur) as follows:

(a)The Rent Adjustment Deposit representing Tenant’s Share of Operating Expenses for the applicable calendar year (or partial calendar year), monthly during the Term with the payment of Monthly Base Rent;

(b)The Rent Adjustment Deposit representing Tenant’s Share of Taxes for the applicable calendar year (or partial calendar year), monthly during the Term with the payment of Monthly Base Rent;

(c)Any Rent Adjustments due in excess of the Rent Adjustment Deposits in accordance with Section 4.2. Rent Adjustments due from Tenant to Landlord for any Lease Year shall be Tenant’s Share of Operating Expenses for such Lease Year and Tenant’s Share of Taxes for such Lease Year; and

(d)For purposes of determining Rent Adjustments, if the Building or Property is not fully occupied during all or a portion of any calendar year (or partial calendar year), Landlord shall make appropriate adjustments to the variable components of Operating Expenses for such calendar year (or partial calendar year), employing sound accounting and management principles consistently applied, to determine the amount of Operating Expenses that would have been paid or incurred by Landlord had the Building or Property been fully occupied, and the amount so determined shall be deemed to have been the amount of Operating Expenses for such calendar year (or partial calendar year). In the event that the Property is not fully assessed for all or a portion of any calendar year (or partial calendar year) during the Term, then Taxes shall be adjusted to an amount which would have been payable in such calendar year (or partial calendar year) if the Property had been fully assessed.

On or before April 1 of each calendar year (or as soon thereafter as practical), Landlord will furnish to Tenant a statement (“Landlord’s Statement”) respecting the prior calendar year showing the following:

(b)The amount of Rent Adjustments due Landlord for the last calendar year, less credit for Rent Adjustment Deposits paid, if any; and

(c)Any change in the Rent Adjustment Deposit due monthly in the current calendar year, including the amount or revised amount due for months preceding any such change pursuant to Landlord’s Statement.

Tenant shall pay to Landlord within thirty (30) days after receipt of each Landlord’s Statement any amounts for Rent Adjustments then due in accordance with such Landlord’s Statement. Any amounts due from Landlord to Tenant pursuant to this Section shall be credited to the Rent Adjustment Deposit next coming due or refunded to Tenant if the Term has expired, provided Tenant is not in Default hereunder. No interest or penalties shall accrue on any amounts that Landlord is obligated to credit or refund to Tenant by reason of this Section 4.2. Landlord’s failure to deliver Landlord’s Statement or to compute the amount of the Rent Adjustments shall not constitute a waiver by Landlord of its right to deliver such items nor constitute a waiver or release of Tenant’s obligations to pay such amounts. The Rent Adjustment Deposit shall be credited against Rent Adjustments due for the applicable calendar year (or partial calendar year). During the last complete calendar year (or partial calendar year) or during any partial calendar year in which this Lease terminates, Landlord may include in the Rent Adjustment Deposit its estimate of Rent Adjustments which may not be finally determined until after the termination of this Lease. Tenant’s obligation to pay Rent Adjustments and Landlord’s obligation to refund any Rent Adjustment Deposit to Tenant shall survive the expiration or termination of this Lease.

Landlord shall maintain books and records showing Operating Expenses and Taxes in accordance with sound accounting and management practices, consistently applied. Tenant or its representative (which representative shall be a certified public accountant licensed to do business in the state in which the Property is located and whose primary business is certified public accounting and who shall not be paid on a contingency basis) shall have the right, for a period of ninety (90) days following the date upon which Landlord’s Statement is delivered to Tenant, to examine the Landlord’s books and records with respect to the items in the foregoing statement of Operating Expenses and Taxes during normal business hours, upon written notice, delivered at least three (3) business days in advance. Tenant shall pay for all costs of such examination, provided, however, if such examination results in a discrepancy of more than five percent (5%) in the actual Operating Expenses and Taxes from those shown on the Landlord’s Statement, such costs shall be reimbursed by Landlord. If Tenant does not object in writing to Landlord’s Statement within ninety (90) days of Tenant’s receipt thereof, specifying the nature of the item in dispute and the reasons therefor, then Landlord’s Statement shall be considered final and accepted by Tenant and Tenant shall be deemed to have waived its right to dispute Landlord’s Statement. If Tenant does dispute any item in the Landlord’s Statement, Tenant shall give notice of such dispute to Landlord and deliver a copy of any such audit to Landlord at the time of notification of the dispute. If Tenant does not provide such notice of dispute and a copy of such audit to Landlord within such ninety (90) day period, it shall be deemed to have waived such right to dispute Landlord’s Statement. Any amount due to Landlord as shown on Landlord’s Statement, whether or not disputed by Tenant as provided herein shall be paid by Tenant when due as provided above, without prejudice to any such written exception. In no event shall Tenant be permitted to examine Landlord’s records or to dispute any statement of Operating Expenses and Taxes while Tenant is in Default under this Lease. Upon resolution of any dispute with respect to Operating Expenses and/or Taxes, Tenant shall either pay Landlord any shortfall or Landlord shall credit Tenant with respect to any overages paid by Tenant (or promptly pay such amount directly to Tenant, if there are not sufficient months left in the Term to credit such amount to). The records obtained by Tenant shall be treated as confidential and neither Tenant nor any of its representatives or agents (including without limitation any financial or legal consultants) shall disclose or discuss the information set forth in the audit to or with any other person or entity except (a) to Tenant’s lawyers and accountants, or (b) as required by applicable law (“Confidentiality Requirement”). Tenant shall indemnify and hold Landlord harmless for any losses or damages arising out of the breach of the Confidentiality Requirement.

In addition to Monthly Base Rent, Rent Adjustments, Rent Adjustment Deposits and other charges to be paid by Tenant, Tenant shall pay to Landlord, within thirty (30) days following receipt of written demand, any and all taxes payable by Landlord (other than federal or state inheritance, franchise, general income, gift or estate taxes) whether or not now customary or within the contemplation of the parties hereto: (a) upon, allocable to, or measured by the Rent payable hereunder, including any gross receipts tax or excise tax levied by any governmental or taxing body with respect to the receipt of such rent; or (b) upon or with respect to the possession, leasing, operation, management, maintenance, alteration, repair, use or occupancy by Tenant of the Premises or any portion thereof; or (c) upon the measured value of Tenant’s personal property

located in the Premises or in any storeroom or any other place in the Premises or the Property, or the areas used in connection with the operation of the Property, it being the intention of Landlord and Tenant that, to the extent possible, such personal property taxes shall be billed to and paid directly by Tenant; (d) resulting from any Landlord Work, Tenant Work, Tenant Alterations, or any other improvements to the Premises, whether title thereto is in Landlord or Tenant; or (e) upon this transaction; provided, however, Tenant shall not have any obligation to pay such taxes to the extent they are already included in the calculation of the Operating Expenses for the Project. Taxes paid by Tenant pursuant to this Section 4.4 shall not be included in any computation of Taxes payable pursuant to Sections 4.1 and 4.2.

Concurrently with the execution of this Lease, Tenant shall pay to Landlord the Security Deposit, in immediately available funds. The Security Deposit may be applied by Landlord to cure, in whole or part, any Default of Tenant under this Lease, and upon notice by Landlord of such application, Tenant shall replenish the Security Deposit in full by paying to Landlord within ten (10) days following receipt of written demand from Landlord the amount so applied. Landlord’s application of the Security Deposit shall not constitute a waiver of Tenant’s default to the extent that the Security Deposit does not fully compensate Landlord for all losses, damages, costs and expenses incurred by Landlord in connection with such default and shall not prejudice any other rights or remedies available to Landlord under this Lease or by Law. Landlord shall not pay any interest on the Security Deposit. Landlord shall not be required to keep the Security Deposit separate from its general accounts. The Security Deposit shall not be deemed an advance payment of Rent or a measure of damages for any default by Tenant under this Lease, nor shall it be a bar or defense of any action that Landlord may at any time commence against Tenant. In the absence of evidence satisfactory to Landlord of an assignment of the right to receive the Security Deposit or the remaining balance thereof, Landlord may return the Security Deposit to the original Tenant, regardless of one or more assignments of this Lease. Upon the transfer of Landlord’s interest under this Lease, Landlord’s obligation to Tenant with respect to the Security Deposit shall terminate upon the date Landlord transfers to the transferee of the Security Deposit, or any balance thereof, and such transferee assumes all of Landlord’s obligations under this Lease in writing, including, without limitation, those relating to the Security Deposit. If Tenant shall fully and faithfully comply with all the terms, provisions, covenants, and conditions of this Lease, the Security Deposit, or any balance thereof, shall be returned to Tenant within thirty (30) days after Landlord recovers possession of the Premises. Tenant hereby waives any and all rights of Tenant under the provisions of Section 1950.7 of the California Civil Code or other Law regarding the uses to which security deposits may be applied.

If, upon the expiration of the sixth (6^th) Lease Year, all of the following are true: a) all Rent due has been paid, b) Tenant is not in Default hereunder, c) Tenant’s net worth and liquidity, as calculated pursuant to GAAP, are each not materially less than they were as of the Date of Lease, Landlord agrees that the Security Deposit amount shall be reduced by fifty percent (50%), to become a revised total of $718,789.00, and the difference of $718,789.00 shall be returned to Tenant within ten (10) days following the expiration of the sixth (6^th) Lease Year. Failure of any of the above to be true at the end of the sixth (6^th) Lease Year shall mean the Security Deposit shall remain unchanged in amount for the balance of the Lease Term.

(a)So long as this Lease is in full force and effect, Landlord shall furnish the following services the cost of which services shall be included in Operating Expenses or paid directly by Tenant to utility or service provider:

(1)heat, ventilation and air‑conditioning (“HVAC”) in the Premises during Standard Operating Hours as necessary in Landlord’s reasonable judgment for the comfortable occupancy of the Premises under normal business office and laboratory operations, and (ii) outside of Tenant’s Standard Operating Hours to minimum safe setback levels for laboratory operations (“After-Hours Setback”), subject to compliance with all applicable mandatory regulations and Laws;

(2)tempered and cold water for normal and customary use in the Premises and in lavatories in common with other tenants from the regular supply of the Building;

(3)customary cleaning and janitorial services in the Common Areas five (5) days per week, excluding National Holidays;

(4)washing of the outside windows in the Premises weather permitting at intervals determined by Landlord; and

(5)automatic passenger elevator service in common with other tenants of the Building and freight elevator service subject to reasonable scheduling by Landlord. Tenant shall have access to the Premises seven (7) days per week, twenty-four (24) hours per day, subject to such reasonable measures and systems for access control and/or tenant identification as exist from time to time at the Building, including, for example only, keys or card-keys for entry which shall be provided to Tenant.

(b)Landlord shall provide a security program for the Building (but not individually for Tenant or the Premises) and Tenant’s Parking generally consistent with the standards of comparable office/laboratory buildings in Emeryville. The cost of the security program shall be an Operating Expense. Landlord shall not be liable in any manner to Tenant or any other Tenant Parties for any acts (including criminal acts) of others, or for any direct, indirect, or consequential damages, or any injury or damage to, or interference with, Tenant's business, including, but not limited to, loss of profits, loss of rents or other revenues, loss of business opportunity, loss of goodwill or loss of use, or other loss or damage, bodily injury or death, related to any malfunction, circumvention or other failure of any security program, or for the failure of any security program to prevent bodily injury, death, or property damage, or loss, or to apprehend any person suspected of causing such injury, death, damage or loss.

(c)Upon the Rent Commencement Date, Landlord agrees that in the event of an interruption of power to the Building, Tenant will connect Tenant loads to the emergency generator serving the Building (the “Emergency Generator”) on the following conditions: (i) Tenant loads to the Emergency Generator shall in no event exceed Tenant’s Share of the kVA capacity of the Emergency Generator Landlord elects to make available for shared use by tenants of the Building; (ii) any use of the Emergency Generator, including the duration of use, shall be subject to the requirements and limitations (if any) imposed by applicable Law; and (iii) in the event of an emergency causing an interruption of power to any portion of the Building, Landlord may, in its reasonable discretion, immediately shed or shut down Tenant loads (an “Emergency Shut Down”) to the extent reasonably necessary to redirect the power from the Emergency Generator (“Emergency Generator Power”) to the Building’s emergency/life-safety systems (e.g., elevators, fire-life safety and emergency lighting). To the extent Landlord’s load shedding equipment accommodates shedding Tenant loads in stages, then Landlord shall use commercially reasonable good-faith efforts to shed Tenant loads in a priority which Tenant has delivered to Landlord in writing. As a condition to Tenant’s right to connect Tenant loads to the Emergency Generator:

(i)Tenant shall install and maintain, at Tenant’s sole cost and expense (the cost of which may be deducted from Tenant Improvement Allowance), a meter (the “Meter”), which shall be designed and configured to capture all Tenant loads connected to the Emergency Generator. Any and all reasonable out of pocket costs and expenses incurred by Landlord in connection with the Emergency Generator, including, without limitation, provisions for load-shedding and shunt trips, fuel and maintenance/repair/replacement costs, shall be an Operating Expense; and

(ii)Landlord shall have the right to require Tenant to install and maintain a shunt trip device (“Shunt Trip Device”) designed and configured to automatically shut down Tenant’s connection to the Emergency Generator and use of Emergency Generator Power in the event that the generator load for the Building exceeds eighty percent (80%) of the Emergency Generator rating.

(iii)Tenant shall provide Landlord and Landlord’s building management staff (the “Building Management Staff”) with access to the Meter installed on the Emergency Generator (“EG Meter”) during normal business hours with at least 48 hours’ advance notice for the purpose of inspection. In the event that Tenant fails to repair the EG Meter within thirty (30) days following receipt of written notice from Landlord thereof, Landlord shall have the right to perform necessary maintenance or repairs thereto, and Tenant shall reimburse Landlord for Landlord’s reasonable and customary out-of-pocket costs and expenses in connection therewith within thirty (30) days after Tenant’s receipt of Landlord’s written demand therefor (which demand shall be accompanied by documentation of the costs and expenses which are the subject of such demand). Landlord shall have the right at any time during the Lease Term to install and maintain additional or separate transfer switches, meters, control devices and shunt trip devices in order to monitor and control Tenant’s connection to the Emergency Generator and use of the Emergency Generator Power.

(iv)Notwithstanding anything to the contrary herein, Tenant acknowledges that the Emergency Generator and any transfer switch may be exercised on a periodic basis, such exercise to be conducted by Landlord or the Building Management Staff at Landlord’s reasonable discretion. Tenant further acknowledges that annual maintenance procedures require that the Emergency Generator be taken off-line and that an annual full load test be performed on an annual basis, which test shall be conducted by Landlord or the Building Management Staff at Landlord’s reasonable discretion; provided, however, Landlord shall give Tenant not less than five (5) business days’ prior written notice thereof. Landlord shall not be liable to Tenant, and Tenant shall not be entitled to any abatement of rent or other recourse in the event that Emergency Generator Power is not available for any reason. Landlord’s actual out-of-pocket cost of such exercise and testing shall be included in the maintenance costs, of which Tenant shall pay its proportionate share as set forth above in Paragraph 5(f).

(v)Upon the expiration or earlier termination of the Lease Term, Tenant shall surrender and assign to Landlord the Meter with the Premises. In no event shall Tenant be entitled to any reimbursement from Landlord for costs incurred by Tenant in connection with Tenant’s installation and maintenance of the Meter.

(vi)The rights granted to Tenant under this Section 6.1(c) are personal to the named Tenant hereunder (and any assignee pursuant to a Permitted Transfer) (each an “Approved User”), and shall only be exercisable by an Approved User so long only one connection exists from the Premises to the Emergency Generator at a time. Any attempt by an Approved User or any of its subtenants or other transferees to make any additional connection from the Premises to the Emergency Generator shall constitute a material breach and default, and Tenant shall reimburse Landlord for all reasonable and customary out-of-pocket costs and expenses incurred by Landlord in connection with curing any such default within ten (10) business days following Tenant’s receipt of Landlord’s demand therefor accompanied by documentation of such costs and expenses.

(d)So long as this Lease is in full force and effect, Landlord shall furnish to the Premises replacement lamps, bulbs, ballasts and starters used in any normal Building lighting installed in the Premises, except that if the replacement or repair of such items is a result of negligence of Tenant, its employees, agents, servants, licensees, subtenants, contractors or invitees, such cost shall be paid by Tenant within ten (10) days after notice from Landlord and shall not be included as part of Operating Expenses.

(e)If Tenant uses heat generating machines or equipment in the Premises to an extent which materially and adversely affects the temperature otherwise maintained by the air‑cooling system or whenever the occupancy or electrical load materially and adversely affects the temperature otherwise maintained by the air‑cooling system, and if Tenant fails to eliminate such impact within thirty (30) days following written notice from Landlord, Landlord reserves the right to install or to require Tenant to install supplementary air‑conditioning units to service the Premises. Tenant shall bear all reasonable costs and expenses related to the installation, maintenance and operation of such units.

All utility services used in the production of heating and cooling and air supply and exhaust from the central HVAC systems serving the Building and Premises, including, without limitation, electricity and gas, as well as water and sewer services, shall constitute Operating Expenses. If Landlord so elects, any or all utility services used by Tenant within the Premises, including, without limitation, electricity and gas, shall be paid for by Tenant by separate charge and shall not be included as part of Operating Expenses. Such charges shall be based upon Tenant’s usage as measured by a separate meter or sub-meter for the Premises installed by Tenant at Tenant’s sole cost and expense (the cost of which may be deducted from Tenant Improvement Allowance), a meter, or as reasonably estimated by Landlord and shall be payable by Tenant to Landlord within 30 days after billing by Landlord. In addition, Tenant shall provide its own janitorial services to the Premises, using a janitorial service reasonably acceptable to Landlord or shall make arrangements with Landlord for Landlord, through Landlord’s vendors, to perform such Premises cleaning services, and shall pay the costs thereof directly to Landlord. Notwithstanding any provision of this Lease to the contrary, Tenant shall not make any alterations or additions to the electric equipment or systems, in each instance, without the prior written approval of Landlord, which approval shall not be unreasonably withheld, conditioned or delayed so long as such alterations or additions (i) do not exceed the capacity of the wiring, feeders and risers and (ii) are in compliance with the City’s building code. Tenant’s use of electric current shall at no time exceed the capacity of the wiring, feeders and risers providing electric current to the Premises or the Building. The consent of Landlord to the installation of electric equipment shall not relieve Tenant from the obligation to limit usage of electricity to no more than such capacity.

At Tenant’s written request, Landlord shall furnish additional quantities of any of the services or utilities specified in Section 6.1, if Landlord can reasonably do so, on the terms set forth herein. For services or utilities requested by Tenant and furnished by Landlord, Tenant shall pay to Landlord as a charge therefor Landlord’s prevailing rates charged from time to time for such services and utilities, including, without limitation, HVAC service outside of Standard Operating Hours and beyond After-Hours Setback levels.

All telephone, and communication connections which Tenant may desire shall be subject to Landlord’s prior written approval, in Landlord’s reasonable discretion, and the location of all wires and the work in connection therewith shall be performed by contractors reasonably approved by Landlord, and shall be subject to the direction of Landlord and in compliance with Landlord’s then current Building Standards for voice, data and wiring installation. Notwithstanding the foregoing, such approval is not required for Tenant’s telephone equipment (including cabling) within the Premises and from the Premises in a route reasonably designated by Landlord to any telephone cabinet or panel provided on Tenant’s floor for Tenant’s connection to the telephone cable serving the Building so long as Tenant’s equipment does not require connections different from or additional to those to the telephone cabinet or panel provided. Tenant shall be responsible for and shall pay all costs incurred in connection with the installation of telephone cables and communication wiring in the Premises, including any hook up, access and maintenance fees related

to the installation of such wires and cables in the Premises and the commencement of service therein, and the maintenance thereafter of such wire and cables; and there shall be included in Operating Expenses for the Building all installation, removal, hook up or maintenance costs incurred by Landlord in connection with telephone cables and communication wiring serving the Building which are not allocable to any individual users of such service but are allocable to the Building generally. If Tenant fails to maintain all telephone cables and communication wiring in the Premises, and such failure adversely affects or interferes with the operation or maintenance of any other telephone cables or communication wiring serving the Building, Landlord or any vendor hired by Landlord may enter into and upon the Premises forthwith and perform such repairs, restorations or alterations as Landlord deems reasonably necessary in order to eliminate any such interference (and Landlord may recover from Tenant all of Landlord’s reasonable costs in connection therewith). Tenant agrees that neither Landlord nor any of its agents or employees shall be liable to Tenant, or any of Tenant’s employees, agents, customers or invitees or anyone claiming through, by or under Tenant, for any damages, injuries, losses, expenses, claims or causes of action because of any interruption, diminution, delay or discontinuance at any time for any reason in the furnishing of any telephone or other communication service to the Premises and the Building. Notwithstanding the foregoing to the contrary, to the extent such interruption, diminution, delay or discontinuance is caused by the gross negligence or willful misconduct by Landlord, the property manager, the leasing manager for the Property and their respective partners, members, directors, officers, agents and employees, then Tenant shall be entitled, as its sole remedy, to pursue an action for actual damages (but not punitive, consequential, exemplary, treble or special damages) against Landlord. In no event shall Tenant be entitled to any abatement of Rent or the right to terminate this Lease due to any such interruption, diminution, delay or discontinuance.

Tenant agrees that Landlord shall not be in breach of this Lease nor be liable to Tenant for damages or otherwise, for any failure to furnish, or a delay in furnishing, or a change in the quantity or character of any service when such failure, delay or change is occasioned, in whole or in part, by repairs, improvements or mechanical breakdowns, by the act or default of Tenant or other parties or by an event of Force Majeure. No such failure, delay or change shall be deemed to be an eviction or disturbance of Tenant’s use and possession of the Premises, or relieve Tenant from paying Rent or from performing any other obligations of Tenant under this Lease, without any deduction or offset; provided, however, in the case of any such failure or delay is caused by the gross negligence or willful misconduct of Landlord and the same materially interferes with Tenant’s ability to conduct business in the Premises, then unless Landlord is diligently pursuing a remedy, Rent shall be abated commencing on the fifth (5th) consecutive business day following such failure or delay and shall continue until such time as the failure or delay that materially interferes with Tenant’s ability to conduct business in the Premises is cured. Failure to any extent to make available, or any slowdown, stoppage, or interruption of, the specified utility services resulting from any cause, including changes in service provider or Landlord’s compliance with any voluntary or similar governmental or business guidelines now or hereafter published or any requirements now or hereafter established by any governmental agency, board, or bureau having jurisdiction over the operation of the Property shall not render Landlord liable in any respect for damages to either persons, property, or business, nor be construed as an eviction of Tenant or work an abatement of Rent, nor relieve Tenant of Tenant’s obligations for fulfillment of any covenant

or agreement hereof. Notwithstanding the foregoing, Landlord shall make commercially reasonable efforts to provide Tenant with at least three (3) business days’ notice of any known, planned interruption in utilities or services. Should any equipment or machinery furnished by Landlord break down or for any cause cease to function properly, Landlord shall use reasonable diligence to repair same promptly, but Tenant shall have no claim for abatement of Rent or damages on account of any interruption of service occasioned thereby or resulting therefrom.

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

(a)Initial Building standard signage for Tenant will be installed by Landlord in the directory in the main lobby of the Building and, in the case of any multi-tenant floor, in the listing of tenants in the elevator lobby for the floor on which the Premises is located, at Landlord’s sole cost and expense. In the event Tenant occupies an entire floor of the Building, Tenant may install its own signage in the elevator lobby of such floor, at Tenant’s sole cost and expense, and otherwise in accordance with the provisions of Article 9 below. Any change in such initial signage shall be only with Landlord’s prior written consent (which shall not be unreasonably withheld, conditioned or delayed), shall conform to Building standard signage and shall be at Tenant’s sole cost and expense.

(b)Landlord hereby agrees not to offer exterior, non-exclusive, top of building signage to any other tenant of the Building who has leased two (2) full floors or less without first offering such signage rights to Tenant. Landlord and Tenant hereby agree and acknowledge that if such exterior signage rights are offered by Landlord and accepted by Tenant, Tenant shall pay Landlord the prevailing market rate for such rights, and Landlord and Tenant also agree that the cost to design, secure approvals and permits for, fabricate, install, maintain, repair, remove and restore any such exterior signage shall be at Tenant’s sole cost and expense.

(a)Tenant shall occupy and use the Premises only for the uses specified in Section 1.1(15) to conduct Tenant’s business. Tenant shall not occupy or use the Premises (or permit the use or occupancy of the Premises) for any purpose or in any manner which: (1) is unlawful or in violation of any applicable Law or Environmental Law; (2) may be dangerous to persons or property or which may increase the cost of, or invalidate, any policy of insurance carried on the Building or covering its operations; (3) is contrary to or prohibited by the terms and conditions of this Lease or the rules of the Building set forth in Article 18; (4) creates a nuisance, or (5) in any manner that will cause the Building or any part thereof not to conform with the Project’s Sustainability Practices or the certification of the Building pursuant to the applicable Green Building Standards; provided, however, that in no event shall such practices or certification requirements have the effect of preventing Tenant from conducting its business at the Premises in a manner consistent with the Permitted Use.

(b)Upon Commencement Date, Landlord shall provide Tenant with 250 Access Card Keys the cost of which shall be paid by Tenant within ten (10) days of Landlord’s demand therefor (or at Tenant’s election, the cost thereof may be deducted from Tenant Improvement Allowance), and Tenant shall place a deposit for such cards with Landlord to cover lost cards or cards which are not returned at the end of the Term.

(c)Landlord and Tenant acknowledge that the Americans With Disabilities Act of 1990 (42 U.S.C. §12101 et seq.) and regulations and guidelines promulgated thereunder, as all of the same may be amended and supplemented from time to time (collectively referred to herein as the “ADA”) establish requirements for business operations, accessibility and barrier removal, and that such requirements may or may not apply to the Premises, the Building and the Project depending on, among other things: (1) whether Tenant’s business is deemed a “public accommodation” or “commercial facility”, (2) whether such requirements are “readily achievable”, and (3) whether a given alteration affects a “primary function area” or triggers “path of travel” requirements. The parties hereby agree that, as between Landlord and Tenant, compliance with any accessibility requirement relating to the Common Area and Landlord Work, on an unoccupied basis, promulgated under the ADA shall be responsibility of Landlord (and not Tenant), except to the extent that any specific compliance is triggered by Tenant’s Use in the Premises or any Tenant Alterations, and more specifically, (A) Landlord shall be responsible for ADA Title III compliance in the Common Areas, except as provided below; (B) Tenant shall be responsible for ADA Title III compliance in the Premises, subject to Landlord’s obligation to construct all of the Landlord Work in compliance with all applicable Laws (including ADA), on an unoccupied basis and without regard to Tenant’s specific use of the Premises, the cost of which compliance shall be a Tenant Improvement Allowance Item (as defined in the Workletter); provided, however, Landlord shall make commercially reasonable efforts to cause such ADA Title III compliance to be at the cost of the Architect, Building Consultants, and/or Contractor (all as defined in the Workletter), to the extent such non-compliance was due to any negligent act or omission on any of their parts; (C) Landlord may perform, or require that Tenant perform, and Tenant shall be responsible for the cost of, ADA Title III “path of travel” requirements triggered

by Tenant Additions in the Premises, and (D ) Landlord may perform, or require Tenant to perform, and Tenant shall be responsible for the cost of, ADA Title III compliance in the Common Areas necessitated by the Building being deemed to be a “public accommodation” instead of a “commercial facility” as a result of Tenant’s use of the Premises. Tenant shall be solely responsible for requirements under Title I of the ADA relating to Tenant’s employees.

(d)Civil Code Section 1938. TENANT HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, THE PROTECTIONS OF CALIFORNIA CIVIL CODE SECTION 1938. IF SUCH WAIVER IS NOT ENFORCEABLE UNDER CALIFORNIA LAW, THEN THE FOLLOWING PROVISIONS SHALL APPLY. The Premises have not been issued a disability access inspection certificate or undergone inspection by a Certified Access Specialist (“CASp”). The following notice is given pursuant to California Civil Code Section 1938: “A Certified Access Specialist (CASp) can inspect the subject premises and determine whether the subject premises comply with all of the applicable construction-related accessibility standards under state law. Although state law does not require a CASp inspection of the subject premises, the commercial property owner or lessor may not prohibit the lessee or tenant from obtaining a CASp inspection of the subject premises for the occupancy or potential occupancy of the lessee or tenant, if requested by the lessee or tenant. The parties shall mutually agree on the arrangements for the time and manner of the CASp inspection, the payment of the fee for the CASp inspection, and the cost of making any repairs necessary to correct violations of construction-related accessibility standards within the premises.” Landlord and Tenant hereby agree that if Tenant elects to perform a CASp inspection of the Premises, Tenant will provide written notice to Landlord, and Landlord may elect, in Landlord’s sole discretion, to retain a CASp to perform the inspection. If Landlord does not so elect, the time and manner of the CASp inspection is subject to the prior written approval of Landlord. In either event, the payment of the fee for the CASp inspection shall be borne by Tenant. The cost of making any repairs necessary to correct violations of construction-related accessibility standards within the Premises shall be allocated as provided in this Article.

(e)Tenant agrees to cooperate and use commercially reasonable efforts to participate in traffic management programs provided to Tenant in writing by Landlord, and Tenant shall encourage and support van, shuttle service, and carpooling by, and staggered and flexible working hours for, its office workers and service employees to the extent reasonably permitted by the requirements of Tenant’s business. Neither this Section or any other provision of this Lease is intended to or shall create any rights or benefits in any other person, firm, company, governmental entity or the public.

(f)Tenant agrees to cooperate with Landlord and to comply with any and all reasonable guidelines or controls concerning energy management and usage disclosure imposed upon Landlord by federal or state governmental organizations or by any energy conservation association to which Landlord is a party or which is applicable to the Building, including, without limitation, the requirements of California’s Nonresidential Building Energy Use Disclosure Program, as more particularly specified in California Public Resources Code Sections 25402.10 et seq. and regulations adopted pursuant thereto. Further, Tenant hereby authorizes (and agrees that Landlord shall have the authority to authorize) any electric or gas utility company providing service to the Building to disclose from time to time so much of the data collected and maintained by it regarding Tenant’s energy consumption data as may be necessary to cause the Building to

participate in the ENERGY STAR® Portfolio Manager system and similar programs; and Tenant further authorizes Landlord to disclose information concerning energy use by Tenant, either individually or in combination with the energy use of other tenants, as applicable as Landlord determines to be necessary to comply with applicable Laws pertaining to the Building or Landlord’s ownership thereof.

Landlord reserves the right to monitor, in Landlord’s reasonable discretion and at Landlord’s cost (the reasonable cost of which shall be recoverable as an Operating Expense (except in the case of a breach of any of Tenant’s obligations under this Section, in which event such monitoring costs may be charged back entirely to Tenant and shall be reimbursed by Tenant to Landlord within ten (10) business days after written demand by Landlord from time to time, accompanied by supporting documentation reasonably evidencing the costs for which such reimbursement is claimed), at such times and from time to time as Landlord in its reasonable discretion may determine, through consultants engaged by Landlord or otherwise as Landlord in its reasonable discretion may determine, (x) all aqueous and atmospheric discharges and emissions from the Premises during the Term by a Tenant Party, (y) Tenant’s compliance and the collective compliance of all tenants in the Building with requirements and restrictions relating to the occupancy classification of the Building (including, but not limited to, Hazardous Materials inventory levels of Tenant and all other tenants in the Building), and (z) Tenant’s compliance with all other requirements of this Section.

(9)Discovery of Discharge. If Landlord, Tenant or any governmental or quasi-governmental authority discovers any Release from the Premises during the Term caused by a Tenant Party in violation of this Section that, in Landlord’s reasonable determination, jeopardizes the ability of the Building or the Project to meet applicable Laws or otherwise adversely affects the Building’s or the Project’s compliance with applicable discharge or emission standards, or if Landlord discovers any other breach of Tenant’s obligations under this Section, then upon receipt of written notice from Landlord or at such earlier time as Tenant obtains actual knowledge of the applicable discharge, emission or breach, Tenant at its sole expense shall within a reasonable time (x) in the case of a Release caused by a Tenant Party in violation of this Lease, cease the applicable discharge or emission and remediate any continuing effects of the discharge or emission until such time, if any, as Tenant demonstrates to Landlord’s reasonable satisfaction that the applicable discharge or emission is in compliance with all applicable Laws and any other applicable regulatory commitments and obligations to the satisfaction of the appropriate governmental agency with jurisdiction over the Release, and (y) in the case of any other breach of Tenant’s obligations under this Section, take such corrective measures as Landlord may reasonably request in writing in order to cure or eliminate the breach as promptly as practicable and to remediate any continuing effects of the breach.

(10)Post-Occupancy Study. No later than thirty (30) days prior to the Termination Date, Tenant at its sole cost and expense, shall obtain and deliver to Landlord an environmental study, performed by an expert reasonably satisfactory to Landlord, evaluating, the presence or absence of any Tenant Contamination in, on and about the Premises and the Project. Such study shall be based on a reasonable and prudent level of tests and investigations of the Premises and surrounding portions of the Project (if appropriate) and, if applicable, as required by governing regulatory agencies or bodies for such closure, which tests shall be conducted no earlier than thirty (30) days prior to the Termination Date. Liability for any remedial actions required or recommended on the basis of such study shall be allocated in accordance with the applicable provisions of this Lease. To the extent any such remedial actions are the responsibility of Tenant, Tenant at its sole expense shall promptly commence and diligently pursue to completion the required remedial actions.

(11)Emergency Response Plans. If Landlord in its reasonable discretion adopts any emergency response plan and/or any Contingency Plan and Emergency Procedures for the Building or for multiple Buildings on the Project as contemplated above, Landlord shall provide copies of any such plans and procedures to Tenant and, so long as such plans and procedures are reasonable, comply with applicable Laws, do not unreasonably interfere with Tenant’s use of or access to the Premises or materially increase the cost incurred by Tenant with respect to the Premises. Tenant shall comply with all of the requirements of such plans and procedures to the extent applicable to Tenant and/or the Premises. If Landlord elects to adopt or materially modify any such plans or procedures that apply to the Building during the Term, Landlord shall consult with Tenant, and Tenant shall cooperate, in the preparation of such plans, procedures or modifications in efforts to accurately reflect and maintain consistency with Tenant’s operations in the Premises, but Landlord alone shall determine, in its good faith reasonable discretion, the appropriate scope of such consultation and nothing in this paragraph shall be construed to give Tenant any right of approval or disapproval over Landlord’s adoption or modification of any such plans or procedures so long as such plans and procedures are reasonable. do not unreasonably interfere with Tenant’s use of or access to the Premises or materially increase the cost incurred by Tenant with respect to the Premises.

(12)Radioactive Materials. Without limiting any other applicable provisions of this Section, if Tenant Handles or proposes to Handle any Radioactive Materials in or about the Premises, Tenant shall provide Landlord with copies of Tenant’s licenses or permits for such Radioactive Materials and with copies of all radiation protection programs and procedures required under applicable Laws or otherwise adopted by Tenant from time to time in connection with Tenant’s Handling of such Radioactive Materials. In addition, Tenant shall comply with any and all rules and procedures issued by Landlord in its good faith discretion from time to time with respect to the Handling of Radioactive Materials on the Project (such as, by way of example but not limitation, rules implementing a label defacement program for decayed waste destined for common trash and/or rules relating to transportation and storage of Radioactive Materials on the Project), provided that such rules and procedures shall be reasonable and not in conflict with any applicable Laws.

(13)Deemed Holdover Occupancy. Notwithstanding any other provisions of this Lease, Tenant expressly agrees as follows:

(i)If Tenant Handles any Radioactive Materials in or about the Premises or the Project during the Term, then for so long as any license or permit relating to such Radioactive Materials remains open following the Termination Date, and another entity handling Radioactive Materials which is a prospective tenant of Landlord is legally prohibited from occupying a portion of the Premises for a use similar to Tenant’s use, then Tenant shall be deemed to be occupying that portion of the Premises on a holdover basis without Landlord’s consent (notwithstanding such otherwise applicable termination or expiration of the Term) and shall be required to continue to pay Rent and other charges in accordance with Article 13 solely for that portion of the Premises effected by the radioactive materials license, until such time as all such Radioactive Materials licenses and permits have been fully closed out in accordance with the requirements of this Lease and with all applicable Hazardous Materials Laws and other Laws.

(ii)If Tenant Handles any Hazardous Materials in or about the Premises or the Project during the Term and, on or before the Termination Date, has failed to remove from the Premises or the Project all known Hazardous Materials Handled by a Tenant Party or has failed to complete any remediation or removal of Tenant’s Contamination and/or to have fully remediated in compliance with the requirements of this Lease and with all applicable Hazardous Materials Laws and any other applicable Laws, the Tenant’s Handling and/or Release (if applicable) of any such Hazardous Materials during the Term, then for so long as such circumstances continue to exist, Tenant shall be deemed to be occupying the Premises on a holdover basis without Landlord’s consent (notwithstanding such otherwise applicable termination or expiration of the Term) and shall be required to continue to pay Rent and other charges in accordance with Article 13 until such time as all such circumstances have been fully resolved in accordance with the requirements of this Lease and with all applicable Hazardous Materials Laws and other Laws.

(14)Survival of Obligations. Each party’s obligations under this Section shall survive the Termination Date and shall survive any conveyance by Landlord of its interest in the Premises. The provisions of this Section and any exercise by either party of any of the rights and remedies contained herein shall be without prejudice to any other rights and remedies that such party may have under this Lease or under applicable Law with respect to any Environmental Conditions and/or any Hazardous Materials. Either party’s exercise or failure to exercise, at any time or from time to time, any or all of the rights granted in this Section shall not in any way impose any liability on such party or shift from the other party to such party any responsibility or obligation imposed upon the other party under this Lease or under Hazardous Materials Laws, Environmental Conditions and/or compliance with applicable Laws.

(15)Laboratory Rules and Regulations. Tenant agrees for itself and for its subtenants, employees, agents, and invitees to comply with the laboratory rules and regulations (“Laboratory Rules and Regulations”) attached to this Lease as Exhibit C-1 and with all reasonable modifications and additions thereto which Landlord may make from time to time.

(a)Tenant shall permit Landlord to erect, use and maintain pipes, ducts, wiring and conduits in and through the Premises, so long as Tenant’s use, layout or design of the Premises is not materially affected or altered. Landlord or Landlord’s agents shall have the right to enter upon the Premises (i) to perform scheduled janitorial and other routine services or (ii) in the event of an emergency, or (ii) upon not less than 48 hours’ prior notice, to inspect the Premises, to conduct safety and other testing in the Premises, and to make such repairs, alterations, improvements or additions to the Premises or the Building or other parts of the Property as Landlord may deem necessary or desirable (including all alterations, improvements and additions in connection with a change in service provider or providers) during reasonable times, in all cases, subject to the terms and conditions set forth in this Lease. Janitorial and cleaning services shall be performed after Standard Operating Hours. Any entry or work by Landlord may be during Standard Operating Hours and Landlord shall use reasonable efforts to ensure that any entry or work shall not materially interfere with Tenant’s access to, use and occupancy of the Premises.

(b)Advance notice shall not be required for entry to perform routine janitorial and cleaning services or for entry in the event of an emergency or urgent situation, as reasonably determined by Landlord, but any other entry or work by Landlord shall be upon at least two (2) business day’s prior notice to Tenant, which notice may be delivered orally or by e-mail to Tenant’s on-site manager at the Premises. If Tenant shall not be personally present to permit an entry into the Premises when for any reason an entry therein shall be necessary or permissible, Landlord (or Landlord’s agents), after notifying Tenant (unless Landlord believes an emergency situation exists), may enter the Premises without rendering Landlord or its agents liable therefor, and without relieving Tenant of any obligations under this Lease.

(c)Subject to the entry requirements set forth in this Section 7.1(g)(7), Landlord may enter the Premises for the purpose of conducting such inspections, tests and studies as Landlord may deem reasonably desirable or necessary to confirm Tenant’s compliance with all Laws and Hazardous Materials Laws or for other purposes necessary in Landlord’s reasonable judgment to ensure the sound condition of the Property and the systems serving the Property. Landlord’s rights under this Section 7.2(c) are for Landlord’s own protection only, and Landlord has not, and shall not be deemed to have assumed, any responsibility to Tenant or any other party as a result of the exercise or non‑exercise of such rights, for compliance with Laws or Hazardous Materials Laws or for the accuracy or sufficiency of any item or the quality or suitability of any item for its intended use.

(d)Landlord may do any of the foregoing, or undertake any of the inspection or work described in the preceding paragraphs without such action constituting an actual or constructive eviction of Tenant, in whole or in part, or giving rise to an abatement of Rent by reason of loss or interruption of business of Tenant, or otherwise; provided that such activities are conducted in accordance with the requirements under this Lease.

(e)The review, approval or consent of Landlord with respect to any item required or permitted under this Lease is for Landlord’s own protection only, and Landlord has not, and shall not be deemed to have assumed, any responsibility to Tenant or any other party, as a result of the exercise or non‑exercise of such rights, for compliance with Laws or Hazardous Materials Laws or for the accuracy or sufficiency of any item or the quality or suitability of any item for its intended use.

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

(a)The Property is situated in the City of Emeryville (“City”) in a mixed-use area that includes, among other possible uses permitted by the City, residential, commercial, manufacturing, industrial and laboratory/research uses. In recognition of such mixed-use character of area in which the Property is located, as a condition of the approval of the development of the Building on the Property, the City has required that Landlord disclose to tenants of the Building that:

(1)industrial and laboratory/research uses located in nearby buildings have the potential to emit noise at levels and during hours of the day that persons may find disturbing;

(2)nearby manufacturing, industrial and laboratory/research uses may generate odor;

(4)there is a mainline railroad in the vicinity of the Property that operates 24 hours per day, seven days per week, with associated train horns and other sounds and vibration;

(5)future development in the vicinity of the Property may block views from the Building; and

(6)the site on which the Building is built formerly contained hazardous materials; under the direction of the Environmental Protection Agency and the State Department of Toxic Substances Control (the “Agencies”), remediation and abatement measures have been undertaken to address potential health risks associated with such hazardous materials; and the documents relating to the remediation and abatement measures at the Property are on file at Landlord’s property management office and at the offices of the Agencies (the parties acknowledge that this clause (6) constitutes the notice required by Cal. Health and Safety Code Section 25359.7).

Tenant acknowledges the foregoing disclosures required to be made by Landlord regarding the mixed-use character of the area in which the Property is located.

(b)As required by the terms of that certain Covenant and Restriction referenced hereinbelow, the following notice regarding the land upon which the 6100 Horton Street parking garage is situated is provided:

“The land described herein [i.e., the land upon which the Parking Garage is located] contains polychlorinated biphenyls (PCBs) in soil and volatile organic compounds in groundwater under the Burdened Property referred to as “Emery Station West Parking Garage”, and is subject to a deed restriction dated as of August 11, 2016, and recorded on August 19, 2016, in the Official Records of Alameda County, California, as Document No. 2016210925, which Covenant and Restriction imposes certain covenants, conditions, and restrictions on usage of the property described herein. This statement is not a declaration that a hazard exists.”

(c)During the Lease Term, Landlord shall provide Tenant and its employees reasonable access to any shared lockers and showers serving the Building and other properties owned by Landlord or Landlord’s Affiliates, such access to be free of charge other that for charges customarily charged to all tenants and employees.

Landlord may elect or may be required to develop and implement a Transportation Demand Management (“TDM”) program for the Building in order to reduce the traffic-related impacts resulting from development of the Property. One element of any such TDM program will require tenants of the Building to adopt programs and offer incentives to their employees to reduce auto use and support the increase of alternative modes of transit. The following are examples of such programs and incentives:

•Alternative commute subsidies and/or parking cash-out, where employees are provided with a subsidy if they use transit or commute by alternative modes;

•Opportunities to purchase commuter checks which allow employees to purchase transit tickets at discounted rates from their before-tax income; and

•Compressed work weeks and flex time where employees adjust their work schedules to reduce peak hour trips to/from the Building.

In order to support any such TDM program for the Building, Tenant agrees that it shall use commercially reasonable efforts to adopt programs and offer incentives to its employees in order to reduce auto use and support the increase of alternative modes of transit. The specifics of Tenant’s programs and incentives shall be tailored to the needs of Tenant’s workforce and shall be determined by Tenant in its good faith efforts to meet the goals of the TDM program. Upon request by Landlord from time to time, but not more often than once per calendar year, Tenant shall provide to Landlord a written report summarizing the programs and incentives being offered by Tenant to achieve the goals of the TDM program.

Subject to the provisions of Articles 4 and 14, Landlord shall, as an Operating Expense, maintain and make necessary repairs to the foundations, roofs, exterior walls, and the structural elements of the Building, the electrical, plumbing, heating, ventilating, air‑conditioning, mechanical, communication, security and the fire and life safety systems of the Building and those corridors, washrooms and lobbies which are Common Areas of the Building, except that: (a) Landlord shall not be responsible for the maintenance or repair of any floor or wall coverings in the Premises or any of such systems which are located within the Premises and are supplemental or special to the Building’s standard systems; and (b) the cost of performing any of said maintenance or repairs whether to the Premises or to the Building caused by the negligence of Tenant, its employees, agents, servants, licensees, subtenants, contractors or invitees, shall be paid by Tenant, subject to the waivers set forth in Section 16.4. Landlord shall not be liable to Tenant for any expense, injury, loss or damage resulting from work done in or upon, or in connection with the use of, any adjacent or nearby building, land, street or alley. Notwithstanding the foregoing to the contrary, to the extent such expense, injury, loss or damage is caused by the gross negligence or willful misconduct by Landlord, the property manager, the leasing manager for the Property

and their respective partners, members, directors, officers, agents and employees, then Tenant shall be entitled, as its sole remedy, to pursue an action for actual damages (but not punitive, consequential, exemplary, treble or special damages) against Landlord. In no event shall Tenant be entitled to any abatement of Rent or the right to terminate this Lease due to any such expense, injury, loss or damage.

Tenant shall periodically inspect the Premises to identify any conditions that are dangerous or in need of maintenance or repair. Tenant shall promptly provide Landlord with notice of any such conditions. Tenant shall, at its sole cost and expense, perform all maintenance and repairs to the Premises that are not Landlord’s express responsibility under this Lease, and keep the Premises in good condition and repair, reasonable wear and tear and damages from casualty excepted. Tenant’s repair and maintenance obligations include, without limitation, repairs to: (a) floor covering; (b) interior partitions; (c) doors; (d) the interior side of demising walls; (e) electronic, phone and data cabling, wiring and related equipment that is installed by or for the exclusive benefit of Tenant (collectively, “Cable”); (f) supplemental air conditioning units, kitchens, including hot water heaters, plumbing, and similar facilities exclusively serving Tenant; and (g) Tenant Alterations. To the extent Landlord is not reimbursed by insurance proceeds, Tenant shall reimburse Landlord for the cost of repairing damage to the Building caused by the acts of Tenant, Tenant Parties and their respective contractors and vendors. All maintenance and repairs, including, but not limited to, janitorial and cleaning services, pest control and waste management and recycling performed by or on behalf of Tenant must comply with the Project’s Sustainability Practices and the applicable Green Building Standards. If Tenant fails to make any repairs to the Premises for more than thirty (30) days after notice from Landlord (although notice shall not be required in an emergency), Landlord may make the repairs, and Tenant shall pay the reasonable cost of the repairs, together with an administrative charge in an amount equal to 10% of the cost of the repairs. Tenant hereby waives all right to make repairs at the expense of Landlord or in lieu thereof to vacate the Premises and its other similar rights as provided in California Civil Code Sections 1932(1), 1941 and 1942 or any other Laws (whether now or hereafter in effect). In addition to the foregoing, Tenant shall be responsible for repairing all special tenant fixtures and improvements, including garbage disposals, showers, plumbing, and appliances.

(a)The following provisions shall apply to the completion of any Tenant Alterations:

(1)Tenant shall not, except as provided herein, without the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed, make or cause to be made any Tenant Alterations in or to the Premises or any Building Systems serving the Premises. Prior to making any Tenant Alterations, Tenant shall give Landlord ten (10) days’ prior written notice (or such earlier notice as would be necessary pursuant to applicable Law) to permit Landlord sufficient time to post appropriate notices of non‑responsibility. Subject to all other requirements of this Article 9, Tenant may undertake Decoration work without Landlord’s

prior written consent. Tenant shall furnish Landlord with the names and addresses of all contractors and subcontractors and copies of all contracts. All Tenant Alterations shall be completed at such time and in such manner as Landlord may from time to time designate, and only by contractors or mechanics approved by Landlord, which approval shall not be unreasonably withheld, conditioned or delayed; provided, however, that Landlord may, in its sole discretion, specify the engineers and contractors to perform all work relating to the Building’s Systems (including the mechanical, heating, plumbing, security, ventilating, air‑conditioning, electrical, communication and the fire and life safety systems in the Building). The contractors, mechanics and engineers who may be used are further limited to those whose work will not cause or threaten to cause disharmony or unreasonable interference with Landlord or other tenants in the Building and their respective agents and contractors performing work in or about the Building. Landlord may further condition its consent upon Tenant furnishing to Landlord and Landlord approving prior to the commencement of any work or delivery of materials to the Premises related to the Tenant Alterations such of the following as specified by Landlord (only to the extent applicable and applicable to the type of Tenant Alterations proposed by Tenant): architectural plans and specifications, opinions from Landlord’s engineers stating that the Tenant Alterations will not in any way adversely affect the Building’s systems, necessary permits and licenses, certificates of insurance, and such other documents in such form reasonably requested by Landlord. Landlord may, in the exercise of reasonable judgment, request that Tenant provide Landlord with appropriate evidence of Tenant’s ability to complete and pay for the completion of the Tenant Alterations such as a performance bond or letter of credit for any Tenant Alterations which are expected to cost more than Five Hundred Thousand Dollars ($500,000). Upon completion of the Tenant Alterations, Tenant shall deliver to Landlord an as‑built mylar and digitized (if available) set of plans and specifications for the Tenant Alterations.

(2)Tenant shall pay the cost of all Tenant Alterations and the cost of decorating the Premises and any work to the Property occasioned thereby. Upon completion of Tenant Alterations, Tenant shall furnish Landlord with contractors’ affidavits and full and final waivers of lien and receipted bills covering all labor and materials expended and used in connection therewith and such other documentation reasonably requested by Landlord or Mortgagee.

(3)Tenant agrees to complete all Tenant Alterations (i) in accordance with all Laws, Hazardous Materials Laws, all requirements of applicable insurance companies and in accordance with Landlord’s standard construction rules and regulations, (ii) in a good and workmanlike manner with the use of good grades of materials, and (iii) in accordance with the requirements of the Project’s Sustainability Practices and comply with the applicable Green Building Standards. Tenant shall notify Landlord immediately if Tenant receives any notice of violation of any Law in connection with completion of any Tenant Alterations and shall immediately take such steps as are necessary to remedy such violation. In no event shall such supervision or right to supervise by Landlord nor shall any approvals given by Landlord under this Lease constitute any warranty by Landlord to Tenant of the adequacy of the design, workmanship or quality of such work or materials for Tenant’s intended use or of compliance with the requirements of Section 9.1(a)(3)(i) and (ii) above or impose any liability upon Landlord in connection with the performance of such work.

(b)All Tenant Additions, whether installed by Landlord or Tenant, shall without compensation or credit to Tenant, become part of the Premises and the property of Tenant at the time of their installation and shall remain in the Premises, unless pursuant to Article 12, Tenant may remove them or is required to remove them at Landlord’s request. Any remaining Tenant Additions and Landlord Work shall become the property of Landlord at the expiration or termination of this Lease. For the avoidance of doubt, Tenant shall retain the right to depreciation deductions of all Tenant Alterations made at Tenant’s expense.

Tenant shall not permit any lien or claim for lien of any mechanic, laborer or supplier or any other lien to be filed against the Building, the Land, the Premises, or any other part of the Property arising out of work performed, or alleged to have been performed by, or at the direction of, or on behalf of Tenant; provided that Tenant shall have no obligation for liens or encumbrances caused by Landlord even if such liens or encumbrances arise out of work done on behalf of or for the benefit of Tenant. If any such lien or claim for lien is filed, Tenant shall within twenty (20) days of receiving notice of such lien or claim (a) have such lien or claim for lien released of record or (b) deliver to Landlord a bond in form, content, amount, and issued by surety, reasonably satisfactory to Landlord, indemnifying, protecting, defending and holding harmless the Indemnitees against all costs and liabilities resulting from such lien or claim for lien and the foreclosure or attempted foreclosure thereof. If Tenant fails to take any of the above actions, Landlord, in addition to its rights and remedies under Article 11, without investigating the validity of such lien or claim for lien, may pay or discharge the same and Tenant shall, as payment of additional Rent hereunder, reimburse Landlord upon demand for the amount so paid by Landlord, including Landlord’s expenses and reasonable attorneys’ fees.

(a)Subject to Landlord’s recapture right set forth in Section 10.2, without the prior written consent of Landlord, which consent of Landlord shall not be unreasonably withheld, conditioned or delayed, Tenant may not sublease, assign, mortgage, pledge, hypothecate or otherwise transfer or permit the transfer of this Lease or the encumbering of Tenant’s interest therein in whole or in part, by operation of Law or otherwise or permit the use or occupancy of the Premises, or any part thereof, by anyone other than Tenant. Tenant agrees that the provisions governing sublease and assignment set forth in this Article 10 shall be deemed to be reasonable. If Tenant desires to enter into any sublease of the Premises or assignment of this Lease, Tenant shall deliver written notice thereof to Landlord (“Tenant’s Notice”), together with the identity of the proposed subtenant or assignee and the proposed principal terms thereof and financial and other information sufficient for Landlord to make an informed judgment with respect to such proposed subtenant or assignee at least thirty (30) days prior to the commencement date of the term of the proposed sublease or assignment. If Tenant proposes to sublease a portion of the Premises containing more than 3,000 rentable square feet, the space proposed to be sublet and the space retained by Tenant must each be a marketable unit as reasonably determined by Landlord and otherwise in compliance with all Laws. Landlord shall notify Tenant in writing of its approval or disapproval of the proposed sublease or assignment or its decision to exercise its rights under Section 10.2 within ten (10) business days after receipt of Tenant’s Notice (and all required information). In the event Landlord fails to respond to Tenant's Notice within such ten (10) day period, then Tenant may deliver to Landlord a second (2nd) written request, which must contain the following inscription, in bold faced lettering: “SECOND NOTICE DELIVERED PURSUANT TO SECTION 10.1 OF THE LEASE - - FAILURE TO TIMELY RESPOND WITHIN THREE (3) BUSINESS DAYS SHALL RESULT IN DEEMED APPROVAL OF PROPOSED TRANSFER.” If Landlord fails to respond within such three (3) business day period, then Landlord shall be deemed to have approved the proposed transfer that was the subject of such Tenant Notice. Tenant shall submit for Landlord’s approval (which approval shall not be unreasonably withheld, conditioned or delayed) any advertising which Tenant or its agents intend to use with respect to the space proposed to be sublet.

(b)With respect to Landlord’s consent to an assignment or sublease, Landlord may take into consideration any factors that Landlord may deem relevant in its commercially reasonable judgment, and the reasons for which Landlord’s denial shall be deemed to be reasonable shall include, without limitation, the following:

(i)the business reputation or creditworthiness of any proposed subtenant or assignee is not acceptable to Landlord; or

(ii)in Landlord’s reasonable judgment the proposed assignee or sublessee would diminish the value or reputation of the Project or Landlord; or

(iii)any proposed assignee’s or sublessee’s use of the Premises would violate Section 7.1 of this Lease or would violate the provisions of any other leases of tenants in the Project; or

(iv)the proposed sublessee or assignee is a bona fide prospective tenant of Landlord in the Project as demonstrated by a written proposal dated within six (6) months prior to the date of Tenant’s request and Landlord has vacancy in the Project of a similar size and finish as the space subject to such proposed sublease or assignment; or

(v)the proposed sublessee or assignee would materially increase the estimated pedestrian and vehicular traffic to and from the Premises and the Project above that deemed typical by Landlord for office/lab use in the Project; or

(c)Any sublease or assignment shall be expressly subject to the terms and conditions of this Lease. Any subtenant or assignee shall execute such commercially reasonable and customary documents as Landlord may reasonably require to evidence such subtenant or assignee’s assumption of the obligations and liabilities of Tenant under this Lease. Tenant shall deliver to Landlord a copy of all agreements executed by Tenant and the proposed subtenant and assignee with respect to the Premises. Landlord’s approval of a sublease, assignment, hypothecation, transfer or third party use or occupancy shall not constitute a waiver of Tenant’s obligation to obtain Landlord’s consent to further assignments or subleases, hypothecations, transfers or third party use or occupancy.

(d)For purposes of this Article 10, an assignment shall be deemed to include a change in the majority control of Tenant, resulting from any transfer, sale or assignment of shares of stock of Tenant occurring by operation of Law or otherwise if Tenant is a corporation whose shares of stock are not traded publicly. If Tenant is a partnership, any change in the partners of Tenant shall be deemed to be an assignment.

(e)For purposes of this Lease, a “Permitted Transferee” shall mean any Person which: (i) is an Affiliate; or (ii) is the corporation or other entity (the “Successor”) resulting from a merger, consolidation or non-bankruptcy reorganization with Tenant; or (iii) is otherwise a deemed assignee due to a change of control under Section 10.1(d) above; or (iv) purchases substantially all of the assets of Tenant as a going concern (the “Purchaser”). Notwithstanding anything to the contrary in Sections 10.1(a) and (b) and 10.3, provided there is no uncured Default under this Lease, Tenant shall have the right, without the prior written consent of Landlord, to assign this Lease to a Permitted Transferee or to sublease the Premises or any part thereof to a Permitted Transferee provided that: (1) Landlord receives ten (10) days’ prior written notice of an assignment or sublease (including a proposed transaction described in subparts (i), (ii), (iii) or (iv) of this Section 10.1(e), to the extent such prior notice is permitted under applicable Laws); (2) with respect to an assignment of this Lease or a sublease of more than half the Premises to an entity described in subparts (ii) or (iv) of this Section 10.1(e), the Permitted Transferee’s net worth and liquidity are each not less than Tenant’s net worth immediately prior to such assignment or subletting; (3) with respect to an assignment of this Lease or a sublease of more than half the Premises to an entity described in subparts (i) or (iii) of this Section 10.1(e), Tenant (as the assignor or sublandlord) continues in existence with a net worth not less than Tenant’s net worth

immediately prior to such assignment or subletting; (4) the Permitted Transferee expressly assumes (except a Permitted Transferee which is a deemed assignee under subpart (iii) of this Section 10.1(e) or which is a sublessee in the event of a sublease under this Section 10.1(e)) in writing reasonably satisfactory to Landlord all of the obligations of Tenant under this Lease and delivers such assumption to Landlord no later than fifteen (15) days following the effective date of the assignment; (5) Landlord receives no later than five (5) days following the effective date a fully executed copy of the applicable assignment or sublease agreement between Tenant and the Permitted Transferee; (6) promptly after Landlord’s written request, Tenant and the Permitted Transferee provide such reasonable documents and information which Landlord reasonably requests for the purpose of substantiating whether or not the assignment or sublease is to a Permitted Transferee; and (7) such transfer is not being entered into for the primary purpose of avoiding the requirement for Landlord’s prior consent or the provisions of Sections 10.2 or 10.3. All determinations of net worth and liquidity for purposes of this Subsection shall exclude any value attributable to goodwill or going concern value.

(f)With respect to any sublease hereunder, subject to Section 10.3 below, Tenant hereby irrevocably assigns to Landlord, effective upon any such sublease, all rent and other payments due from subtenant under the sublease, provided however, that Tenant shall have a license to collect such rent and other payments until the occurrence of a Default by Tenant under any of the provisions of this Lease. At any time after such Default, at Landlord’s option, Landlord shall have the right to give notice to the subtenant of such assignment. Landlord shall credit Tenant with any rent received by Landlord under such assignment, but the acceptance of any payment on account of rent from the subtenant as the result of any such default shall in no manner whatsoever serve to release Tenant from any liability under the terms, covenants, conditions, provisions or agreement under this Lease. No such payment of rent or any other payment by the subtenant directly to Landlord and/or acceptance of such payment(s) by Landlord, regardless of the circumstances or reasons therefor, shall in any manner whatsoever be deemed an attornment by the subtenant to Landlord in the absence of a specific written agreement signed by Landlord to such an effect.

Excluding any assignment or sublease contemplated in Section 10.1(e), if Tenant requests an assignment of this Lease or a sublease of the entire Premises for any period or a sublease for at least seventy-five (75%) of the Premises for the remainder of the then-current Term, Landlord shall have the option to exclude from the Premises covered by this Lease (“recapture”) the space proposed to be sublet or subject to assignment, effective as of the proposed commencement date of such sublease or proposed effective date of such assignment. If Landlord elects to recapture, Tenant shall have the right to revoke the request to so sublet or assign by providing Landlord written notice thereof no later than five (5) days following Landlord’s recapture notice to Tenant in which case, the Premises shall not be transferred, and this Lease will remain in full force and effect with respect to the entirety of the Premises then-existing as of the date of such request or consent by Tenant. If Landlord elects to recapture and Tenant has not revoked its request for consent, Tenant shall surrender possession of the space proposed to be subleased or subject to the assignment to Landlord on the effective date of recapture of such space from the Premises, such date being the Termination Date for such space. Effective as of the date of recapture of any portion of the Premises pursuant to this section, the Monthly Base Rent, Rentable Area of the Premises and Tenant’s Share shall be adjusted accordingly.

Except in connection with any assignment or sublease contemplated in Section 10.1(e), Tenant shall pay Landlord on the first day of each month during the term of the sublease or assignment, fifty percent (50%) of the amount by which the sum of all rent and other consideration (direct or indirect) due from the subtenant or assignee for such month exceeds: a) that portion of the Monthly Base Rent and Rent Adjustments due under this Lease for said month which is allocable to the space sublet or assigned, and b) the following costs and expenses for the subletting or assignment of such space: (i) brokerage commissions and attorneys’ fees and expenses, (ii) the actual costs paid in making any improvements or substitutions in the Premises required by any sublease or assignment; and (iii) “free rent” periods, costs of any inducements or concessions given to subtenant or assignee, moving costs, and other amounts in respect of such subtenant’s or assignee’s other leases or occupancy arrangements.

In the event of any sublease or assignment, whether or not with Landlord’s consent, Tenant shall not be released or discharged from any liability, whether past, present or future, under this Lease, including any liability arising from the exercise of any renewal or expansion option, to the extent such exercise is expressly permitted by Landlord. Tenant’s liability shall remain primary, and in the event of default by any subtenant, assignee or successor of Tenant in performance or observance of any of the covenants or conditions of this Lease, Landlord may proceed directly against Tenant without the necessity of exhausting remedies against said subtenant, assignee or successor. In addition, if Tenant has any options to extend the Term or to add other space to the Premises, such options shall not be available to any subtenant or assignee (other than Permitted Transferees), directly or indirectly without Landlord’s express written consent, which may be withheld in Landlord’s sole discretion.

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

Tenant shall pay to Landlord, as Landlord’s cost of processing each proposed assignment or subletting (whether or not the same is ultimately approved by Landlord or consummated by Tenant) except in connection with Permitted Transfers, an amount equal to the sum of (i) Landlord’s reasonable attorneys’ and other professional fees, not to exceed $2,000, plus (ii) the sum of $1,500.00 for the cost of Landlord’s administrative, accounting and clerical time (collectively, “Processing Costs”). Notwithstanding anything to the contrary herein, Landlord shall not be required to process any request for Landlord’s consent to an assignment or subletting until Tenant has paid to Landlord the amount of Landlord’s estimate of the Processing Costs. When the actual amount of the Processing Costs is determined, it shall be reconciled with Landlord’s estimate, and any payments or refunds required as a result thereof shall promptly thereafter be made by the parties.

Any assignment or sublease effected without Landlord’s consent in violation of this Article 10 shall, at Landlord’s option, be a non-curable Default under Section 11.1 without the necessity of any notice and grace period.

The occurrence or existence of any one or more of the following shall constitute a “Default” by Tenant under this Lease:

(i)Tenant fails to pay any installment or other payment of Rent including Rent Adjustment Deposits or Rent Adjustments when due, where such failure shall continue for a period of five (5) days after Tenant’s receipt of written notice thereof from Landlord;

(ii)Tenant fails to observe or perform any of the other covenants, conditions or provisions of this Lease or the Workletter and fails to cure such default within thirty (30) days after written notice thereof to Tenant, unless the default involves a hazardous condition, which shall be cured forthwith or unless the failure to perform is a Default for which this Lease specifies there is no cure or grace period. Notwithstanding the foregoing, if any such cure cannot be reasonably completed within such thirty (30) day period, Tenant shall have such longer period as needed to complete such cure (up to ninety (90) days, subject to extension due to Force Majeure) so long as the cure is commenced within such thirty (30) day period and Tenant diligently pursues to completion;

(iii)Tenant fails to maintain any insurance policy required hereunder, and fails to cure such default within five (5) business days after written notice thereof to Tenant;

(iv)Tenant abandons the Premises for a period of ten (10) consecutive days or any abandonment of the Premises by Tenant which would cause any insurance policy to be invalidated or otherwise lapse, in each of forgoing cases if Tenant is then in monetary default under this Lease;

(v)an assignment or sublease, or attempted assignment or sublease, of this Lease or the Premises by Tenant contrary to the provisions of Article 10, unless such assignment or sublease is expressly conditioned upon Tenant having received Landlord’s consent thereto;

(vi)the interest of Tenant in this Lease is levied upon under execution or other legal process;

(vii)a petition is filed by or against Tenant to declare Tenant bankrupt or seeking a plan of reorganization or arrangement under any Chapter of the Bankruptcy Act, or any amendment, replacement or substitution therefor, or to delay payment of, reduce or modify Tenant’s debts, which in the case of an involuntary action is not discharged within sixty (60) days;

(viii)Tenant is declared insolvent by Law or any assignment of Tenant’s property is made for the benefit of creditors;

(ix)a receiver is appointed for Tenant or Tenant’s property, which appointment is not discharged within thirty (30) days;

(x)any action taken by or against Tenant to reorganize or modify Tenant’s capital structure in a materially adverse way which in the case of an involuntary action is not discharged within thirty (30) days; or

(a)A Default shall constitute a breach of this Lease for which Landlord shall have the rights and remedies set forth in this Section 11.2 and all other rights and remedies set forth in this Lease or now or hereafter allowed by Law, whether legal or equitable, and all rights and remedies of Landlord shall be cumulative and none shall exclude any other right or remedy now or hereafter allowed by applicable Law.

(b)With respect to a Default, at any time Landlord may terminate Tenant’s right to possession by written notice to Tenant stating such election. Any written notice required pursuant to Section 11.1 shall constitute notice of unlawful detainer pursuant to California Code of Civil Procedure Section 1161 if, at Landlord’s sole discretion, it states Landlord’s election that Tenant’s right to possession is terminated after expiration of any period required by Law or any longer period required by Section 11.1. Upon the expiration of the period stated in Landlord’s written notice of termination (and unless such notice provides an option to cure within such period and Tenant cures the Default within such period), Tenant’s right to possession shall terminate and this Lease shall terminate, and Tenant shall remain liable as hereinafter provided. Upon such termination in writing of Tenant’s right to possession, Landlord shall have the right, subject to applicable Law, to re‑enter the Premises and dispossess Tenant and the legal representatives of Tenant and all other occupants of the Premises by unlawful detainer or other summary proceedings, or as otherwise permitted by Law, regain possession of the Premises and remove their property (including their trade fixtures, personal property and Required Removables pursuant to Article 12), but Landlord shall not be obligated to effect such removal, and such property may, at Landlord’s option, be stored elsewhere, sold or otherwise dealt with as permitted by Law, at the risk of, expense of and for the account of Tenant, and the proceeds of any sale shall be applied pursuant to Law. Landlord shall in no event be responsible for the value, preservation or safekeeping of any such property. Tenant hereby waives all claims for damages that may be caused by Landlord’s removing or storing Tenant’s personal property pursuant to this Section or Section 12.1, and Tenant hereby indemnifies, and agrees to defend, protect and hold harmless, the Indemnitees from any and all loss, claims, demands, actions, expenses, liability and cost (including attorneys’ fees and expenses) arising out of or in any way related to such removal or storage. Upon

such written termination of Tenant’s right to possession and this Lease, Landlord shall have the right to recover damages for Tenant’s Default as provided herein or by Law, including the following damages provided by California Civil Code Section 1951.2:

(1)the worth at the time of award of the unpaid Rent which had been earned at the time of termination;

(2)the worth at the time of award of the amount by which the unpaid Rent which would have been earned after termination until the time of award exceeds the amount of such Rent loss that Tenant proves could reasonably have been avoided;

(3)the worth at the time of award of the amount by which the unpaid Rent for the balance of the Term of this Lease after the time of award exceeds the amount of such Rent loss that Tenant proves could be reasonably avoided; and

(4)any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result therefrom, including, without limitation, Landlord’s unamortized costs of tenant improvements, leasing commissions and legal fees incurred in connection with entering into this Lease.

The word “rent” as used in this Section 11.2 shall have the same meaning as the defined term Rent in this Lease. The “worth at the time of award” of the amount referred to in clauses (1) and (2) above is computed by allowing interest at the Default Rate. The worth at the time of award of the amount referred to in clause (3) above is computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one percent (1%). For the purpose of determining unpaid Rent under clause (3) above, the monthly Rent reserved in this Lease shall be deemed to be the sum of the Monthly Base Rent, monthly storage space rent, if any, and the amounts last payable by Tenant as Rent Adjustments for the calendar year in which Landlord terminated this Lease as provided hereinabove.

(c)Even if Tenant is in Default and/or has abandoned the Premises, this Lease shall continue in effect for so long as Landlord does not terminate Tenant’s right to possession by written notice as provided in Section 11.2(b) above, and Landlord may enforce all its rights and remedies under this Lease, including the right to recover Rent as it becomes due under this Lease. In such event, Landlord shall have all of the rights and remedies of a landlord under California Civil Code Section 1951.4 (Landlord may continue Lease in effect after Tenant’s Default and abandonment and recover Rent as it becomes due, if Tenant has the right to sublet or assign, subject only to reasonable limitations), or any successor statute. During such time as Tenant is in Default, if Landlord has not terminated this Lease by written notice and if Tenant requests Landlord’s consent to an assignment of this Lease or a sublease of the Premises, subject to Landlord’s option to recapture pursuant to Section 10.2, Landlord shall not unreasonably withhold, condition or delay its consent to such assignment or sublease. Tenant acknowledges and agrees that in the absence of written notice pursuant to Section 11.2(b) above terminating Tenant’s right to possession, no other act of Landlord shall constitute a termination of Tenant’s right to possession or an acceptance of Tenant’s surrender of the Premises, including acts of maintenance or preservation or efforts to re-let the Premises or the appointment of a receiver upon initiative of Landlord to protect Landlord’s interest under this Lease or the withholding of consent to a subletting or assignment, or terminating a subletting or assignment, if in accordance with other provisions of this Lease.

(d)in the event that Landlord seeks an injunction with respect to a breach or threatened breach by Tenant of any of the covenants, conditions or provisions of this Lease, Tenant agrees to pay the premium for any bond required in connection with such injunction.

(e)Tenant hereby waives any and all rights to relief from forfeiture, redemption or reinstatement granted by Law (including California Civil Code of Procedure Sections 1174 and 1179) in the event of Tenant being evicted or dispossessed for any cause or in the event of Landlord obtaining possession of the Premises by reason of Tenant’s Default or otherwise;

(f)Notwithstanding any other provision of this Lease, a notice to Tenant given under this Article and Article 24 of this Lease or given pursuant to California Code of Civil Procedure Section 1161, and any notice served by mail, shall be deemed served, and the requisite waiting period deemed to begin under said Code of Civil Procedure Section upon mailing (except as may be required under Code of Civil Procedure Section 1161 et seq.), without any additional waiting requirement under Code of Civil Procedure Section 1011 et seq. or by other Law. For purposes of Code of Civil Procedure Section 1162, Tenant’s “place of residence”, “usual place of business”, “the property” and “the place where the property is situated” shall mean and be the Premises, whether or not Tenant has vacated same at the time of service.

(g)The voluntary or other surrender or termination of this Lease, or a mutual termination or cancellation thereof, shall not work a merger and shall terminate all or any existing assignments, subleases, subtenancies or occupancies permitted by Tenant, except if and as otherwise specified in writing by Landlord.

(h)No delay or omission in the exercise of any right or remedy of Landlord upon any default by Tenant, and no exercise by Landlord of its rights pursuant to Section 26.16 to perform any duty which Tenant fails timely to perform, shall impair any right or remedy or be construed as a waiver. No provision of this Lease shall be deemed waived by Landlord unless such waiver is in writing signed by Landlord. The waiver by Landlord of any breach of any provision of this Lease shall not be deemed a waiver of any subsequent breach of the same or any other provision of this Lease.

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

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

(a)In connection with any proceeding under Chapter 7 of the Bankruptcy Code where the trustee of Tenant elects to assume this Lease for the purposes of assigning it, such election or assignment, may only be made upon compliance with the provisions of subclauses (b) and (c) below, which conditions Landlord and Tenant acknowledge to be commercially reasonable. In the event the trustee elects to reject this Lease then Landlord shall immediately be entitled to possession of the Premises without further obligation to Tenant or the trustee.

(b)Any election to assume this Lease under Chapter 11 or 13 of the Bankruptcy Code by Tenant as debtor‑in‑possession or by Tenant’s trustee (the “Electing Party”) must provide for the Electing Party to cure or provide to Landlord adequate assurance that it will cure all monetary defaults under this Lease within fifteen (15) days from the date of assumption and that it will cure all nonmonetary defaults under this Lease within thirty (30) days from the date of assumption. Landlord and Tenant acknowledge such condition to be commercially reasonable.

(c)If the Electing Party has assumed this Lease or elects to assign Tenant’s interest under this Lease to any other person, such interest may be assigned only if the intended assignee has provided adequate assurance of future performance (as herein defined), of all of the obligations imposed on Tenant under this Lease.

(d)For the purposes hereof, “adequate assurance of future performance” means that Landlord has ascertained that each of the following conditions has been satisfied:

(i)The assignee has submitted a current financial statement, certified by its chief financial officer, which shows a net worth and working capital in amounts sufficient to assure the future performance by the assignee of Tenant’s obligations under this Lease; and

(ii)Landlord has obtained consents or waivers from any third parties that may be required under a lease, mortgage, financing arrangement, or other agreement by which Landlord is bound, to enable Landlord to permit such assignment.

(e)Landlord’s acceptance of rent or any other payment from any trustee, receiver, assignee, person, or other entity will not be deemed to have waived, or waive, the requirement of Landlord’s consent, Landlord’s right to terminate this Lease for any transfer of Tenant’s interest under this Lease without such consent, or Landlord’s claim for any amount of Rent due from Tenant.

Landlord shall be in default hereunder in the event Landlord has not commenced and pursued with reasonable diligence the cure of any failure of Landlord to meet its obligations hereunder within thirty (30) days after the receipt by Landlord of written notice from Tenant of the alleged failure to perform. Failure to provide the requisite notice and cure period by Tenant under this paragraph shall be an absolute defense by Landlord against any claims for failure to perform any of its obligations. In no event shall Tenant have the right to terminate or rescind this Lease as a result of Landlord’s default as to any covenant or agreement contained in this Lease. Tenant hereby waives such remedies of termination and rescission and hereby agrees that Tenant’s remedies for default hereunder and for breach of any promise or inducement shall be limited to a suit for damages and/or injunction. In addition, Tenant hereby covenants that, prior to the exercise of any such remedies, it will give the Mortgagee notice and a reasonable time to cure any default by Landlord, provided that Tenant has received written notice of the address of such Mortgagee.

Upon the Termination Date, Tenant shall surrender and vacate the Premises immediately and deliver possession thereof to Landlord in a broom-clean, good and tenantable condition, excepting ordinary wear and tear, repairs and maintenance for which Landlord is responsible under this Lease and damage caused by casualty and/or Landlord. Tenant shall deliver to Landlord all keys to the Premises. All permanent improvements in and to the Premises (other than Tenant’s trade fixtures, equipment and personal property), including any Tenant Alterations (collectively, “Leasehold Improvements”) shall remain upon the Premises at the end of the Term without compensation to Tenant. Landlord, however, by written notice to Tenant at least 90 days prior to the Termination Date, may require Tenant, at its expense, to remove (a) any Cable, and (b) any Tenant Additions that, in Landlord’s reasonable judgment, are of a nature that would require removal and repair costs that are materially in excess of the removal and repair costs associated with standard laboratory and office improvements, as applicable, only to the extent Landlord notified Tenant of such required removal at the time Landlord approved such Tenant Addition (collectively referred to as “Required Removables”). Required Removables shall include, without limitation, raised floors, personal baths and showers, vaults, rolling file systems and structural alterations and modifications. The designated Required Removables shall be removed by Tenant before the Termination Date. Tenant’s removal and disposal of items pursuant to this Paragraph 12 must comply with the Project’s Sustainability Practices and the applicable Green Building Standards. Tenant shall repair damage caused by the installation or removal of Required Removables. If Tenant fails to perform its obligations in a timely manner, Landlord may perform such work at Tenant’s expense. Tenant, at the time it requests approval for a proposed Tenant Alteration, may request in writing that Landlord advise Tenant whether the proposed Tenant Alteration or any portion of the proposed Tenant Alteration is a Required Removable. Within 10 days after receipt of Tenant’s request, Landlord shall advise Tenant in writing as to which portions of the proposed Tenant Alterations are Required Removables. If any of the Tenant Additions which were installed by Tenant involved the lowering of ceilings, raising of floors or the

installation of specialized wall or floor coverings or lights, unless otherwise approved by Landlord, then Tenant shall also be obligated to return such surfaces to their condition prior to the commencement of this Lease. Tenant shall also be required to close any staircases or other openings between floors. In the event possession of the Premises is not delivered to Landlord when required hereunder, or if Tenant shall fail to remove those items described above, Landlord may (but shall not be obligated to), at Tenant’s expense, remove any of such property and store, sell or otherwise deal with such property, and undertake, at Tenant’s expense, such restoration work as Landlord deems necessary or advisable.

All property which remains in the Premises after the Termination Date (including any of Tenant’s trade fixtures, equipment and personal property) shall be conclusively presumed to have been abandoned by Tenant, and Landlord may deal with such property as provided in Section 11.2(b), including the waiver and indemnity obligations provided in that Section. Tenant shall also reimburse Landlord for all costs and expenses incurred by Landlord in removing any Required Removables Tenant failed to remove prior to the Termination Date and in restoring the Premises to the condition required by this Lease. For the period prior to the Termination Date, Landlord hereby waives any lien rights which it may otherwise have concerning Tenant’s furniture, fixtures, equipment and/or supplies at the Premises, and Tenant shall have the right to remove the same at any time without Landlord’s consent.

In the event that Tenant holds over in possession of the Premises after the Termination Date, for each month or partial month Tenant holds over possession of the Premises, Tenant shall pay Landlord 150% of the monthly Base Rent payable for the month immediately preceding the holding over, as well as Rent Adjustments during the period of such holding over, as the same may be reasonably estimated by Landlord). Tenant shall also pay all damages, but not including consequential damages, sustained by Landlord by reason of such holding over. The provisions of this Article 13 shall not constitute a waiver by Landlord of any re‑entry rights of Landlord, and Tenant’s continued occupancy of the Premises shall be as a tenancy in sufferance.

(a)If any fire or other casualty (whether insured or uninsured) renders all or a substantial portion of the Premises or the Building untenantable, Landlord shall, with reasonable promptness after the occurrence of such damage, cause a licensed and qualified architect or contractor to estimate the length of time that will be required to substantially complete the repair and restoration and shall, by notice advise Tenant of such estimate (“Landlord’s Notice”). If Landlord’s Notice indicates that the amount of time required to substantially complete such repair and restoration will exceed one hundred eighty (180) days from the date such damage occurred,

then Landlord, or Tenant if all or a substantial portion of the Premises is rendered untenantable, shall have the right to terminate this Lease as of the date of such damage by delivering written notice to the other at any time within thirty (30) days after delivery of Landlord’s Notice, provided that if Landlord so chooses, Landlord’s Notice may also constitute such notice of termination.

(b)Unless this Lease is terminated as provided in the preceding subparagraph, Landlord shall proceed with reasonable promptness to repair and restore the Premises to its condition as existed prior to such casualty, subject to reasonable delays for insurance adjustments and Force Majeure delays, and also subject to zoning Laws and building codes then in effect. Landlord shall have no liability to Tenant, and Tenant shall not be entitled to terminate this Lease if such repairs and restoration are not in fact completed within the time period estimated by Landlord so long as Landlord shall proceed with reasonable diligence to complete such repairs and restoration. Notwithstanding the foregoing, if Landlord is obligated to repair or restore the Premises pursuant to this Section 14.1(b) and does not Commence (as defined below in this Section 14.1(b)) such repair or restoration within ninety (90) days after such obligation shall accrue (the “Outside Start Date”), which Outside Start Date shall be subject to extension due to Force Majeure, Tenant shall have the right, as its sole remedy, to terminate this Lease effective as of the date that is thirty (30) days after the Outside Start Date (the “Casualty Lease Termination Date”) by giving written notice thereof to Landlord (“Tenant’s Termination Notice”) within fifteen (15) days after the Outside Start Date; provided, however, that if Landlord does Commence the repair or restoration on or before the Casualty Lease Termination Date, Tenant’s election to termination shall be null and void and this Lease shall continue in full force and effect. “Commence” shall mean either the unconditional authorization of the preparation of the required plans necessary for such repair or restoration, or the beginning of the actual work to repair or restore the Premises, whichever first occurs. In order for Tenant to have the termination right provided for in this Section 14.1(b), Tenant’s Termination Notice must (i) be concurrently sent to any Mortgagee whose address has been provided to Tenant, and (ii) state Tenant’s intention to terminate this Lease as of the Casualty Lease Termination Date.

(c)Tenant acknowledges that Landlord shall be entitled to the full proceeds of any insurance coverage, whether carried by Landlord or Tenant, for damages to the Premises, except for (i) those proceeds of Tenant’s insurance of its own personal property, trade fixtures and equipment which would be removable by Tenant at the Termination Date, and (ii) proceeds of any business interruption insurance maintained by Tenant. All such insurance proceeds shall be payable to Landlord whether or not the Premises are to be repaired and restored, provided, however, if this Lease is not terminated and the parties proceed to repair and restore Tenant Additions at Tenant’s cost, to the extent Landlord received proceeds of Tenant’s insurance covering Tenant Additions, such proceeds shall be applied to reimburse Tenant for its cost of repairing and restoring Tenant Additions.

(d)Notwithstanding anything to the contrary herein set forth: (i) Landlord shall have no duty pursuant to this Section to repair or restore any portion of any Tenant Additions or to expend for any repair or restoration of the Premises or Building in amounts in excess of insurance proceeds paid to Landlord and available for repair or restoration; and (ii) Tenant shall not have the right to terminate this Lease pursuant to this Section if any damage or destruction was caused by the act or neglect of Tenant, its agent or employees. Whether or not this Lease is terminated pursuant to this Article 14, in no event shall Tenant be entitled to any compensation or damages for loss of the use of the whole or any part of the Premises or for any inconvenience or annoyance occasioned by any such damage, destruction, rebuilding or restoration of the Premises or the Building or access thereto.

(e)Any repair or restoration of the Premises performed by Tenant shall be in accordance with the provisions of Article 9 hereof.

If the Premises or the Building is damaged by a casualty but neither is rendered substantially untenantable for the Permitted Use, and Landlord’s Notice indicates that the time to substantially complete the repair or restoration will not exceed one hundred eighty (180) days from the date such damage occurred, then Landlord shall proceed to repair and restore the Building and/or the Premises other than Tenant Additions, with reasonable promptness, unless such damage is to the Premises and occurs during the last twelve (12) months of the Term (regardless of the estimated repair time), in which event either Tenant or Landlord shall have the right to terminate this Lease as of the date of such casualty by giving written notice thereof to the other within thirty (30) days after the date of such casualty. Notwithstanding the aforesaid, Landlord’s obligation to repair shall be limited in accordance with the provisions of Section 14.1 above.

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

The provisions of this Lease, including this Article 14, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, the Premises or the Property or any part of either, and any Law, including Sections 1932(2), 1933(4), 1941 and 1942 of the California Civil Code, with respect to any rights or obligations concerning damage or destruction shall have no application to this Lease or to any damage to or destruction of all or any part of the Premises or the Property or any part of either, and are hereby waived.

In the event the whole or any substantial part of the Building or of the Premises is taken or condemned by any competent authority for any public use or purpose (including a deed given in lieu of condemnation) and is thereby rendered untenantable or such taking could reasonably expected to have a material adverse effect on Tenant’s ability to operate its business at the Premises in substantially the same manner operated by Tenant prior to such taking, this Lease shall terminate as of the date title vests in such authority, and Monthly Base Rent and Rent Adjustments shall be apportioned as of the Termination Date. Notwithstanding anything to the contrary herein set forth,

in the event the taking is temporary (for less than the remaining Term of this Lease), Landlord may elect either (i) to terminate this Lease, or (ii) permit Tenant to receive the entire award attributable to the Premises in which case Tenant shall continue to pay Rent and this Lease shall not terminate.

In the event a part of the Building or the Premises is taken or condemned by any competent authority (or a deed is delivered in lieu of condemnation) and this Lease is not terminated, this Lease shall be amended to reduce or increase, as the case may be, the Monthly Base Rent and Tenant’s Share to reflect the Rentable Area of the Premises or Building, as the case may be, remaining after any such taking or condemnation. Landlord, upon receipt and to the extent of the award in condemnation (or proceeds of sale) shall make necessary repairs and restorations to the Premises (exclusive of Tenant Additions) and to the Building to the extent necessary to constitute the portion of the Building not so taken or condemned as a complete architectural and economically efficient unit. Notwithstanding the foregoing, if as a result of any taking, or a governmental order that the grade of any street or alley adjacent to the Building is to be changed and such taking or change of grade makes it necessary or desirable to substantially remodel or restore the Building or prevents the economical operation of the Building, Landlord shall have the right to terminate this Lease upon ninety (90) days’ prior written notice to Tenant.

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

Tenant, at Tenant’s expense, agrees to maintain in force, with a company or companies acceptable to Landlord, during the Term: (a) Commercial General Liability Insurance on a primary basis and without any right of contribution from any insurance carried by Landlord covering the Premises on an occurrence basis against all claims for personal injury, bodily injury, death and property damage, including contractual liability covering the indemnification provisions in this Lease, and such insurance shall be for such limits that are reasonably required by Landlord from time to time but not less than a combined single limit (each occurrence and in the aggregate) of Five Million and No/100 Dollars ($5,000,000.00) (which limit may be achieved through use of umbrella coverage); (b) Workers’ Compensation and Employers’ Liability Insurance to the extent required by and in accordance with the Laws of the State of California; (c) “All Risks” property insurance in an amount adequate to cover the full replacement cost of all Tenant Additions, equipment, installations, fixtures and contents of the Premises (including coverage in the event of loss from earthquake, water damage, and earthquake sprinkler leakage, up to a maximum coverage

amount of Five Million and No/100 Dollars ($5,000,000.00)); (d) in the event a motor vehicle is to be used by Tenant in connection with its business operation from the Premises, Comprehensive Automobile Liability Insurance coverage with limits of not less than One Million and No/100 Dollars ($1,000,000.00) combined single limit coverage against bodily injury liability and property damage liability arising out of the use by or on behalf of Tenant, its agents and employees in connection with this Lease, of any owned, non-owned or hired motor vehicles; (e) environmental liability (also known as “Pollution Legal Liability”) coverage with limits of not less than One Million and No/100 Dollars ($1,000,000.00) to cover Tenant’s indemnity obligations pursuant to Section 7.1(f)(5) above; and (f) such other insurance or coverages as Landlord reasonably requires, so long as such coverages are then required for all comparable tenants of the Project.

Each policy referred to in Section 16.1 shall satisfy the following requirements. Each policy shall (i) name Landlord and the Indemnitees as additional insureds (except Workers’ Compensation and Employers’ Liability Insurance), (ii) be issued by one or more responsible insurance companies licensed to do business in the State of California reasonably satisfactory to Landlord, (iii) where applicable, provide for deductible amounts satisfactory to Landlord and not permit co‑insurance, and (iv) each policy of “All‑Risks” property insurance shall provide that the policy shall not be invalidated should the insured waive in writing prior to a loss, any or all rights of recovery against any other party for losses covered by such policies. Tenant shall deliver to Landlord, certificates of insurance (and at Landlord’s request, copies of all policies and renewals thereof to be maintained by Tenant hereunder), prior to Tenant’s entry into the Premises and prior to the expiration date of each policy. Additionally, Tenant shall provide Landlord written notice of any cancelation or amendment of any such insurance within two (2) business days following Tenant’s knowledge of the same. If Tenant fails to carry the insurance required under this Article 16 or fails to provide certificates of renewal as and when required hereunder, Landlord may, but shall not be obligated to acquire such insurance on Tenant’s behalf or Tenant’s sole cost and expense.

Landlord agrees to purchase and keep in full force and effect during the Term hereof, including any extensions or renewals thereof, insurance under policies issued by insurers of recognized responsibility, qualified to do business in the State of California on the Building in amounts sufficient to cover the replacement cost thereof, insuring against fire and such other risks as may be included in standard forms of all risk coverage insurance reasonably available from time to time. Landlord agrees to maintain in force during the Term, Commercial General Liability Insurance covering the Building on an occurrence basis against all claims for personal injury, bodily injury, death, and property damage. Such insurance shall be for a combined single limit (each occurrence and in the aggregate) of not less than Five Million and No/100 Dollars ($5,000,000.00) (which limit may be achieved through use of umbrella coverage). Neither Landlord’s obligation to carry such insurance nor the carrying of such insurance shall be deemed to be an indemnity by Landlord with respect to any claim, liability, loss, cost or expense due, in whole or in part, to Tenant’s negligent acts or omissions or willful misconduct. Without obligation to do so, Landlord may, in its sole discretion from time to time, carry insurance in amounts greater and/or for coverage additional to the coverage and amounts set forth above.

(a)Landlord agrees that, if obtainable at no, or minimal, additional cost, and so long as the same is permitted under the laws of the State of California, it will include in its “All Risks” policies appropriate clauses pursuant to which the insurance companies (i) waive all right of subrogation against Tenant with respect to losses payable under such policies and/or (ii) agree that such policies shall not be invalidated should the insured waive in writing prior to a loss any or all right of recovery against any party for losses covered by such policies.

(b)Tenant agrees to include, if obtainable at no, or minimal, additional cost, and so long as the same is permitted under the laws of the State of California, in its “All Risks” insurance policy or policies on Tenant Additions, whether or not removable, and on Tenant’s furniture, furnishings, fixtures and other property removable by Tenant under the provisions of this Lease, appropriate clauses pursuant to which the insurance company or companies (i) waive the right of subrogation against Landlord and/or any tenant of space in the Building with respect to losses payable under such policy or policies and/or (ii) agree that such policy or policies shall not be invalidated should the insured waive in writing prior to a loss any or all right of recovery against any party for losses covered by such policy or policies. If Tenant is unable to obtain in such policy or policies either of the clauses described in the preceding sentence, Tenant shall, if legally possible and without necessitating a change in insurance carriers, have Landlord named in such policy or policies as an additional insured. If Landlord shall be named as an additional insured in accordance with the foregoing, Landlord agrees to endorse promptly to the order of Tenant, without recourse, any check, draft, or order for the payment of money representing the proceeds of any such policy or representing any other payment growing out of or connected with said policies, and Landlord does hereby irrevocably waive any and all rights in and to such proceeds and payments.

(c)Provided that Landlord’s right of full recovery under its policy or policies aforesaid is not adversely affected or prejudiced thereby, Landlord hereby waives any and all right of recovery which it might otherwise have against Tenant, its servants, agents and employees, for loss or damage occurring to the Real Property and the fixtures, appurtenances and equipment therein, to the extent the same is covered by Landlord’s insurance, notwithstanding that such loss or damage may result from the negligence or fault of Tenant, its servants, agents or employees. Provided that Tenant’s right of full recovery under its aforesaid policy or policies is not adversely affected or prejudiced thereby, Tenant hereby waives any and all right of recovery which it might otherwise have against Landlord, its servants, and employees and against every other tenant of the Real Property who shall have executed a similar waiver as set forth in this Section 16.4 (c) for loss or damage to Tenant Additions, whether or not removable, and to Tenant’s furniture, furnishings, fixtures and other property removable by Tenant under the provisions hereof to the extent the same is coverable by Tenant’s insurance required under this Lease, notwithstanding that such loss or damage may result from the negligence or fault of Landlord, its servants, agents or employees, or such other tenant and the servants, agents or employees thereof.

(d)Landlord and Tenant hereby agree to advise the other promptly if the clauses to be included in their respective insurance policies pursuant to subparagraphs (a) and (b) above cannot be obtained on the terms hereinbefore provided. Landlord and Tenant hereby also agree to notify the other promptly of any cancellation or change of the terms of any such policy that would affect such clauses.

Tenant shall give Landlord notice in case of a fire or accident in the Premises promptly after Tenant is aware of such event.

To the extent permitted by Law, Tenant hereby releases the Indemnitees from, and waives all claims for, damage to person or property sustained by Tenant or any occupant of the Premises or the Property resulting directly or indirectly from any existing or future condition, defect, matter or thing in and about the Premises or the Property or any part of either or any equipment or appurtenance therein, or resulting from any accident in or about the Premises or the Property, or resulting directly or indirectly from any act or neglect of any tenant or occupant of the Property or of any other person, including Landlord’s agents and servants, except to the extent caused by the gross negligence or willful and wrongful act of any of the Indemnitees. To the extent permitted by Law, Tenant hereby waives any consequential damages, compensation or claims for inconvenience or loss of business, rents, or profits as a result of such injury or damage, whether or not caused by the gross negligence or willful and wrongful act of any of the Indemnitees. If any such damage, whether to the Premises or the Property or any part of either, or whether to Landlord or to other tenants in the Property, results from any act or negligence of Tenant, its employees, servants, agents, contractors, invitees or customers, Tenant shall be liable therefor and Landlord may, at Landlord’s option, repair such damage and Tenant shall, upon demand by Landlord, as payment of additional Rent hereunder, reimburse Landlord within thirty (30) days of demand for the total cost of such repairs, in excess of amounts, if any, paid to Landlord under insurance covering such damages. Tenant shall not be liable for any such damage caused by its acts or negligence if Landlord or a tenant has recovered the full amount of the damage from proceeds of insurance policies and the insurance company has waived its right of subrogation against Tenant.

To the extent permitted by Law, and except to the extent indemnified by Landlord under Section 17.3, Tenant hereby indemnifies, and agrees to protect, defend and hold the Indemnitees harmless, against any and all actions, claims, demands, liability, costs and expenses, including reasonable attorneys’ fees and expenses for the defense thereof, arising from Tenant’s occupancy of the Premises, from the undertaking of any Tenant Additions or repairs to the Premises by Tenant, from the conduct of Tenant’s business on the Premises, or from any breach or default on the part of Tenant in the performance of any covenant or agreement on the part of Tenant to be performed pursuant to the terms of this Lease, or from any willful act or negligence of Tenant, its agents, contractors, servants, employees, customers or invitees, in or about the Premises or the Property or any part of either. In case of any action or proceeding brought against the Indemnitees by reason of any such claim, upon notice from Landlord, Tenant covenants to defend such action or proceeding by counsel reasonably acceptable to Landlord. Landlord reserves the right to settle, compromise or dispose of any and all actions, claims and demands related to the foregoing indemnity. The foregoing indemnity shall not operate to relieve Indemnitees of liability to the

extent such liability is caused by the willful and wrongful act of Indemnitees. Further, the foregoing indemnity is subject to and shall not diminish any waivers in effect in accordance with Section 16.4 by Landlord or its insurers to the extent of amounts, if any, paid to Landlord under its “All‑Risks” property insurance. This Article 17 shall survive the expiration or earlier termination of this Lease.

To the extent permitted by Law, Landlord hereby indemnifies, and agrees to protect, defend and hold Tenant, its partners, members, directors, officers, agents and employees (the “Tenant Indemnitees”) harmless, against any and all actions, claims, demands, liability, costs and expenses, including reasonable attorneys’ fees and expenses for the defense thereof, arising from any willful act or the gross negligence of Landlord, in or about the Premises or the Property or any part of either. In case of any action or proceeding brought against the Tenant Indemnitees by reason of any such claim, upon notice from Tenant, Landlord covenants to defend such action or proceeding by counsel chosen by Landlord. The foregoing indemnity shall not operate to relieve Tenant Indemnitees of liability to the extent such liability is caused by the willful and wrongful act of the Tenant Indemnitees. Further, the foregoing indemnity is subject to and shall not diminish any waivers in effect in accordance with Section 16.4 by Tenant or its insurers to the extent of amounts, if any, paid to Tenant under its “All‑Risks” property insurance.

To the extent permitted by law, Tenant hereby waives and releases the Indemnitees from any consequential damages, compensation or claims for inconvenience or loss of business, rents or profits as a result of any injury or damage, whether or not caused by the willful and wrongful act of any of the Indemnitees.

Tenant agrees for itself and for its subtenants, employees, agents, and invitees to comply with the rules and regulations listed on Exhibit C-2 attached hereto and with all reasonable modifications and additions thereto which Landlord may make from time to time and provided to Tenant in writing, provided that such modifications and additions apply to all tenants generally and non-discriminatory manner. In the event of any conflict between such rules and regulations and any provision in this Lease, such provision of this Lease shall control.

Nothing in this Lease shall be construed to impose upon Landlord any duty or obligation to enforce the rules and regulations as set forth on Exhibit C-2 or as hereafter adopted, or the terms, covenants or conditions of any other lease as against any other tenant, and Landlord shall not be liable to Tenant for violation of the same by any other tenant, its servants, employees, agents, visitors or licensees. Landlord shall use reasonable efforts to enforce the rules and regulations of the Project in a uniform and non‑discriminatory manner.

Landlord shall have the following rights exercisable without notice to Tenant and without liability to Tenant for damage or injury to persons, property or business and without being deemed an eviction or disturbance of Tenant’s use or possession of the Premises or giving rise to any claim for offset or abatement of Rent: (1) to change the Building’s name or street address upon thirty (30) days’ prior written notice to Tenant; (2) to install, affix and maintain all signs on the exterior and/or interior of the Building; (3) to designate and/or approve prior to installation, all types of signs, window shades, blinds, drapes, awnings or other similar items, and all internal lighting that may be visible from the exterior of the Premises; (4) upon reasonable written notice to Tenant, to display the Premises to prospective purchasers and lenders at reasonable hours at any time during the Term and to prospective tenants at reasonable hours during the last twelve (12) months of the Term, subject to Tenant’s reasonable security and safety rules and procedures (which may include, without limitation, requiring a Tenant representative to escort visitors at all times); (5) to grant to any party the exclusive right to conduct any business or render any service in or to the Building, provided such exclusive right shall not operate to unreasonably interfere with Tenant’s use of the Premises for the purpose permitted hereunder; (6) to change the arrangement and/or location of entrances or passageways, doors and doorways, corridors, elevators, stairs, washrooms or public portions of the Building, and to close entrances, doors, corridors, elevators or other facilities, provided that such action shall not materially and adversely interfere with Tenant’s access to the Premises or the Building or unreasonably interfere with Tenant’s use of the Preemies for the purposes permitted hereunder; (7) to have access for Landlord and other tenants of the Building to any mail chutes and boxes located in or on the Premises as required by any applicable rules of the United States Post Office; and (8) to close the Building after Standard Operating Hours, except that Tenant and its employees and invitees shall be entitled to admission at all times, under such reasonable regulations as Landlord prescribes for the Building for security purposes.

At any time during the Term, Landlord may substitute for the Premises, other premises in the Building, in which event the New Premises shall be deemed to be the Premises for all purposes under this Lease, provided that (i) the New Premises shall be located on higher floors in the Building than the Premises and shall be substantially similar to the Premises in area, configuration and functionality; (ii) if Tenant is then occupying the Premises, Landlord shall pay the actual and reasonable expenses of physically moving Tenant, its property and equipment to the New Premises; (iii) Landlord shall give Tenant not less than ninety (90) days’ prior written notice of such substitution; and (iv) Landlord, at its expense, shall improve the New Premises with improvements substantially similar to those in the Premises at the time of such substitution, if the Premises are then improved.

Within ten (10) business days after request therefor by Landlord, Mortgagee or any prospective mortgagee or owner, Tenant agrees as directed in such request to execute an Estoppel Certificate in recordable form, binding upon Tenant, certifying (i) that this Lease is unmodified and in full force and effect (or if there have been modifications, a description of such modifications and that this Lease as modified is in full force and effect); (ii) the dates to which Rent has been paid; (iii) that Tenant is in the possession of the Premises, if that is the case; (iv) that to the best knowledge of Tenant without any duty to investigate, Landlord is not in default under this Lease (or if Tenant believes Landlord is in default, the nature thereof in detail); (v) that to the best knowledge of Tenant without any duty to investigate, Tenant has no offsets or defenses to the performance of its obligations under this Lease (or if Tenant believes there are any offsets or defenses, a full and complete explanation thereof); (vi) that the Premises have been completed in accordance with the terms and provisions hereof or the Workletter, that Tenant has accepted the Premises and the condition thereof and of all improvements thereto and has no claims against Landlord or any other party with respect thereto (or stating such exceptions thereto as applicable); (vii) that if an assignment of rents or leases has been served upon the Tenant by a Mortgagee, Tenant will acknowledge receipt thereof and agree to be bound by the reasonable provisions thereof; (viii) that Tenant will give to the Mortgagee copies of all notices required or permitted to be given by Tenant to Landlord, provided that the Mortgagee’s address is provided to Tenant in writing; and (ix) to any other factual information reasonably and customarily requested.

In the event that Tenant fails to deliver an Estoppel Certificate within three (3) days of its receipt of a second written notice from Landlord to Tenant after the expiration of the initial ten (10) day period, then such failure shall be a Default for which there shall be no cure or grace period. In addition to any other remedy available to Landlord, Tenant shall be deemed to have irrevocably appointed Landlord as Tenant’s attorney-in-fact to execute and deliver such Estoppel Certificate.

Within ten (10) business days after request therefor by Tenant, Landlord shall also certify that (i) that this Lease is unmodified and in full force and effect (or if there have been modifications, a description of such modifications and that this Lease as modified is in full force and effect); (ii) the dates to which Rent has been paid; (iii) whether or not to the best knowledge of Landlord without any duty to investigate, Tenant is in default in the performance of any covenant, agreement or condition contained in this Lease and, if so, specifying each such default of which Landlord may have knowledge.

Tenant represents that, except for the broker(s) listed in Section 1.1(17), Tenant has not dealt with any real estate broker, sales person, or finder in connection with this Lease, and no such person initiated or participated in the negotiation of this Lease, or showed the Premises to Tenant. Landlord represents that, except for the broker(s) listed in Section 1.1(17), Landlord has not dealt with any real estate broker, sales person, or finder in connection with this Lease, and no such person initiated or participated in the negotiation of this Lease, or showed the Premises on behalf of Landlord. Tenant hereby agrees to indemnify, protect, defend and hold Landlord and the Indemnitees, harmless from and against any and all liabilities and claims for commissions and fees arising out of a breach of the foregoing representation as well as from any claim or claims for any commission or fee by any broker or other party claiming to represent Tenant in connection with any future extensions or renewals hereof. Landlord hereby agrees to indemnify, protect, defend and hold Tenant and the Tenant Indemnitees, harmless from and against any and all liabilities and claims for commissions and fees arising out of a breach of the foregoing representation by Landlord as well as from any claim or claims for any commission or fee by any broker or other party claiming to represent Landlord in connection with any future extensions or renewals hereof. Landlord agrees to pay any commission to which the brokers listed in Section 1.1(17) are entitled in connection with this Lease pursuant to Landlord’s written agreement with such broker.

This Lease is and shall be expressly subject and subordinate at all times to (i) any ground or underlying lease of the Real Property, now or hereafter existing, and all amendments, extensions, renewals and modifications to any such lease, and (ii) the lien of any mortgage or trust deed now or hereafter encumbering fee title to the Real Property and/or the leasehold estate under any such lease, and all amendments, extensions, renewals, replacements and modifications of such mortgage or trust deed and/or the obligation secured thereby, unless such ground lease or ground lessor, or mortgage, trust deed or Mortgagee, expressly provides or elects that this Lease shall be superior to such lease or mortgage or trust deed. If any such mortgage or trust deed is foreclosed (including any sale of the Real Property pursuant to a power of sale), or if any such lease is terminated, upon request of the Mortgagee or ground lessor, as the case may be, Tenant shall, provided that such Mortgagee or ground lessor agrees not to disturb Tenant’s rights under this Lease if Tenant is not in Default hereunder, attorn to the purchaser at the foreclosure sale or to the ground lessor under such lease, as the case may be, provided, however, that such purchaser or ground lessor shall not be (i) bound by any payment of Rent for more than one month in advance except payments in the nature of security for the performance by Tenant of its obligations under this Lease; (ii) subject to any offset, defense or damages arising out of a default of any obligations of any preceding Landlord; (iii) bound by any amendment or modification of this Lease made without the written consent of the Mortgagee or ground lessor, or (iv) liable for any security deposits not actually received in cash by such purchaser or ground lessor. This subordination shall

be self‑operative and no further certificate or instrument of subordination need be required by any such Mortgagee or ground lessor. In confirmation of such subordination, however, Tenant shall execute promptly any commercially reasonable certificate or instrument that Landlord, Mortgagee or ground lessor may request. Tenant hereby constitutes Landlord as Tenant’s attorney‑in‑fact to execute such certificate or instrument for and on behalf of Tenant upon Tenant’s failure to do so within fifteen (15) days of a request to do so. Upon request by such successor in interest, Tenant shall execute and deliver reasonable instruments confirming the attornment provided for herein. The terms of this paragraph shall survive any termination of this Lease by reason of foreclosure.

During the thirty (30) day period following the Date of this Lease, Landlord shall use commercially reasonable efforts to obtain a subordination, non-disturbance and attornment agreement (a "SNDA") from the current Mortgagee in a form reasonably acceptable to Tenant; provided, however, in no event shall Landlord be in default of this Lease if, despite Landlord’s exercise of commercially reasonable efforts, Landlord is unable to obtain a SNDA for Tenant from any such Mortgagee. Additionally, notwithstanding anything herein to the contrary, Tenant’s obligation to subordinate this Lease to any future ground lease or mortgage as provided above is conditioned upon Landlord providing a SNDA from such future Mortgagee on the standard form provided by such Mortgagee (with such commercially reasonable modifications as may be requested by Tenant and approved by such Mortgagee).

Tenant agrees to give any Mortgagee or ground lessor, by registered or certified mail, a copy of any notice of default served upon Landlord by Tenant, provided that prior to such notice Tenant has received written notice (by way of service on Tenant of a copy of an assignment of rents and leases, or otherwise) of the address of such Mortgagee or ground lessor. Tenant further agrees that if Landlord shall have failed to cure such default within the time provided for in this Lease, then the Mortgagee or ground lessor shall have an additional thirty (30) days after receipt of notice thereof within which to cure such default or if such default cannot be cured within that time, then such additional notice time as may be necessary, if, within such thirty (30) days, any Mortgagee or ground lessor has commenced and is diligently pursuing the remedies necessary to cure such default (including the commencement of foreclosure proceedings or other proceedings to acquire possession of the Real Property, if necessary to effect such cure). Such period of time shall be extended by any period within which such Mortgagee or ground lessor is prevented from commencing or pursuing such foreclosure proceedings or other proceedings to acquire possession of the Real Property by reason of Landlord’s bankruptcy. Until the time allowed as aforesaid for Mortgagee or ground lessor to cure such defaults has expired without cure, Tenant shall have no right to, and shall not, terminate this Lease on account of default. This Lease may not be modified or amended so as to reduce the Rent or shorten the Term, or so as to adversely affect in any other respect to any material extent the rights of Landlord, nor shall this Lease be canceled or surrendered, without the prior written consent, in each instance, of the ground lessor or the Mortgagee. Landlord agrees to diligently use reasonable efforts to obtain such Mortgagee consents as may be required and shall promptly inform Tenant in writing upon obtaining such consents.

(a)All notices, demands or requests provided for or permitted to be given pursuant to this Lease must be in writing and shall be personally delivered, sent by Federal Express or other reputable overnight courier service, or mailed by first class, registered or certified United States mail, return receipt requested, postage prepaid, or sent by electronic mail, provided that the sender also sends a hard copy of the notice within one (1) business day by one of the other methods.

(b)All notices, demands or requests to be sent pursuant to this Lease shall be deemed to have been properly given or served by delivering or sending the same in accordance with this Section, addressed to the parties hereto at their respective addresses listed in Section 1.1.

(c)Notices, demands or requests sent by mail or overnight courier service as described above shall be effective upon deposit in the mail or with such courier service. However, except with respect to a notice given under Code of Civil Procedure Section 1161 et seq., the time period in which a response to any such notice, demand or request must be given shall commence to run from (i) in the case of delivery by mail, the date of receipt on the return receipt of the notice, demand or request by the addressee thereof, or (ii) in the case of delivery by Federal Express or other overnight courier service, the date of acceptance of delivery by an employee, officer, director or partner of Landlord or Tenant. Rejection or other refusal to accept or the inability to deliver because of changed address of which no notice was given, as indicated by advice from Federal Express or other overnight courier service or by mail return receipt, shall be deemed to be receipt of notice, demand or request sent. Notices may also be served by personal service upon any officer, director or partner of Landlord or Tenant, and shall be effective upon such service.

(d)By giving to the other party at least thirty (30) days’ written notice thereof, either party shall have the right from time to time during the term of this Lease to change their respective addresses for notices, statements, demands and requests, provided such new address shall be within the United States of America.

Landlord advises Tenant hereby that the purpose of this Article is to provide to the Landlord information and assurances to enable Landlord to comply with the law relating to OFAC.

Tenant hereby represents, warrants and covenants to Landlord, either that (i) Tenant is regulated by the SEC, FINRA or the Federal Reserve (a “Regulated Entity”) or (ii) neither Tenant nor any person or entity that directly or indirectly (a) controls Tenant or (b) has an ownership interest in Tenant of twenty-five percent (25%) or more, appears on the list of Specially Designated Nationals and Blocked Persons (“OFAC List”) published by the Office of Foreign Assets Control (“OFAC”) of the U.S. Department of the Treasury.

If, in connection with this Lease, there is one or more Guarantors of Tenant’s obligations under this Lease, then Tenant further represents, warrants and covenants either that (i) any such Guarantor is a Regulated Entity or (ii) neither Guarantor nor any person or entity that directly or indirectly (a) controls such Guarantor or (b) has an ownership interest in such Guarantor of twenty-five percent (25%) or more, appears on the OFAC List.

Tenant covenants that during the term of this Lease to provide to Landlord information reasonably requested by Landlord including without limitation, organizational structural charts and organizational documents which Landlord may deem to be necessary (“Tenant OFAC Information”) in order for Landlord to confirm Tenant’s continuing compliance with the provisions of this Article. Tenant represents and warrants that the Tenant OFAC Information it has provided or to be provided to Landlord or Landlord’s Broker in connection with the execution of this Lease is true and complete.

(a)All payments required hereunder (other than the Monthly Base Rent, Rent Adjustments, and Rent Adjustment Deposits, which shall be due as hereinbefore provided) to Landlord shall be paid within ten (10) days after Landlord’s demand therefor if not otherwise set forth in this Lease. All such amounts (including Monthly Base Rent, Rent Adjustments, and Rent Adjustment Deposits) not paid when due shall bear interest from the date due until the date paid at the Default Rate in effect on the date such payment was due.

(b)In the event Tenant is more than five (5) days late in paying any installment of Rent due under this Lease, Tenant shall pay Landlord a late charge equal to five percent (5%) of the delinquent installment of Rent. The parties agree that (i) such delinquency will cause Landlord to incur costs and expenses not contemplated herein, the exact amount of which will be difficult to calculate, including the cost and expense that will be incurred by Landlord in processing each delinquent payment of rent by Tenant, (b) the amount of such late charge represents a reasonable estimate of such costs and expenses and that such late charge shall be paid to Landlord for each delinquent payment in addition to all Rent otherwise due hereunder. The parties further agree that the payment of late charges and the payment of interest provided for in subparagraph (a) above are distinct and separate from one another in that the payment of interest is to compensate Landlord for its inability to use the money improperly withheld by Tenant, while the payment of late charges is to compensate Landlord for its additional administrative expenses in handling and processing delinquent payments.

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

To the fullest extent permitted by law, including laws enacted after the Commencement Date, each party hereto (which includes any assignee, successor, heir or personal representative of a party) shall not seek a jury trial, hereby waives trial by jury, and hereby further waives any objection to venue in the County in which the Project is located, and agrees and consents to personal jurisdiction of the courts of the State of California, in any action or proceeding or counterclaim brought by any party hereto against the other on any matter whatsoever arising out

of or in any way connected with this Lease, the relationship of Landlord and Tenant, Tenant’s use or occupancy of the Premises, or any claim of injury or damage, or the enforcement of any remedy under any statute, emergency or otherwise, whether any of the foregoing is based on this Lease or on tort law. No party will seek to consolidate any such action in which a jury has been waived with any other action in which a jury trial cannot or has not been waived. It is the intention of the parties that these provisions shall be subject to no exceptions. The provisions of this Section shall survive the expiration or earlier termination of this Lease.

Tenant agrees for Tenant and Tenant’s heirs, executors, administrators, successors and assigns and all persons claiming under or through Tenant, and this Lease is made and accepted upon and subject to the following conditions: that there shall be no discrimination against or segregation of any person or group of persons on account of race, color, creed, religion, sex, marital status, national origin or ancestry (whether in the leasing, subleasing, transferring, use, occupancy, tenure or enjoyment of the Premises or otherwise) nor shall Tenant or any person claiming under or through Tenant establish or permit any such practice or practices of discrimination or segregation with reference to the use or occupancy of the Premises by Tenant or any person claiming through or under Tenant.

Within ten (10) days after written request from Landlord from time to time during the Term (not more than once per any 12-month period), Tenant shall provide Landlord with current financial statements setting forth Tenant’s financial condition and net worth for the most recent quarter, including balance sheets and statements of profits and losses. Such statements shall be prepared by an independent accountant and certified by Tenant’s president, chief executive officer or chief financial officer. Landlord shall keep such financial information confidential and shall only disclose such information to Landlord’s lenders, consultants, purchasers or investors, or other agents (who shall be subject to the same confidentiality obligations) on a need to know basis in connection with the administration of this Lease. Notwithstanding the foregoing, Tenant shall have no obligation to deliver any financial statements so long as Tenant is a publicly traded entity and its financial statements are publicly available.

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

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

Landlord represents and warrants to Tenant that it has full authority and power to enter into and perform its obligations under this Lease, that the person executing this Lease is fully empowered to do so, and that no consent or authorization is necessary from any third party (or, if required, such consent has been obtained by Landlord).

This Lease, the exhibits, schedules, and riders attached hereto contain the entire agreement between Landlord and Tenant concerning the Premises and there are no other agreements, either oral or written, and no other representations or statements, either oral or written, on which Tenant has relied. This Lease shall not be modified except by a writing executed by Landlord and Tenant.

If Mortgagee of Landlord requires a modification of this Lease which shall not result in any increased cost or expense to Tenant or in any other substantial and adverse change in the rights and obligations of Tenant hereunder, then Tenant agrees that this Lease may be so modified.

Tenant agrees, on its behalf and on behalf of its successors and assigns, that any liability or obligation under this Lease shall only be enforced against Landlord’s equity interest in the Property up to a maximum of Twenty Million Dollars ($20,000,000.00) and in no event against any other assets of Landlord, or Landlord’s members, officers or directors or partners, and that any liability of Landlord with respect to this Lease shall be so limited and Tenant shall not be entitled to any judgment in excess of such amount. Notwithstanding anything to the contrary contained herein, in no event shall Landlord be liable to Tenant for consequential, punitive or special damages with respect to this Lease.

No payment by Tenant or receipt by Landlord of a lesser amount than any installment or payment of Rent due shall be deemed to be other than on account of the amount due, and no endorsement or statement on any check or any letter accompanying any check or payment of Rent shall be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such installment or payment of Rent or pursue any other remedies available to Landlord. No receipt of money by Landlord from Tenant after the termination of this Lease or Tenant’s right of possession of the Premises shall reinstate, continue or extend the Term. Receipt or acceptance of payment from anyone other than Tenant, including an assignee of Tenant, is not a waiver of any breach of Article 10, and Landlord may accept such payment on account of the amount due without prejudice to Landlord’s right to pursue any remedies available to Landlord.

In the event of any sale or other transfer of the Building, subject to purchaser’s assumption of Landlord’s obligations under this Lease accruing or to be performed after the date of such sale or transfer, Landlord shall be entirely freed and relieved of all agreements and obligations of Landlord hereunder accruing or to be performed after the date of such sale or transfer, and any remaining liability of Landlord with respect to this Lease shall be limited to the dollar amount specified in Section 26.10 and Tenant shall not be entitled to any judgment in excess of such amount.

Subject to the provisions of Article 10, this Lease shall be binding upon and inure to the benefit of Landlord and Tenant and their respective heirs, legal representatives, successors and permitted assigns.

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

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

In the event Tenant abandons the Premises but is otherwise in compliance with all the terms, covenants and conditions of this Lease, Landlord shall (i) have the right to enter into the Premises in order to show the space to prospective tenants, (ii) have the right to reduce the services provided to Tenant pursuant to the terms of this Lease to such levels as Landlord reasonably determines to be adequate services for an unoccupied premises, and (iii) during the last six (6) months of the Term, have the right to prepare the Premises for occupancy by another tenant upon the end of the Term. Tenant expressly acknowledges that in the absence of written notice pursuant to Section 11.2(b) or pursuant to California Civil Code Section 1951.3 terminating Tenant’s right to possession, none of the foregoing acts of Landlord or any other act of Landlord shall constitute a termination of Tenant’s right to possession or an acceptance of Tenant’s surrender of the Premises, and this Lease shall continue in effect.

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

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

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

THIS WORKLETTER (this “Workletter”) is attached to and made a part of that certain Lease (the “Lease”) between EMERY STATION WEST, LLC, a California limited liability company (“Landlord”), and DYNAVAX TECHNOLOGIES CORPORATION, a Delaware corporation (“Tenant”). All capitalized terms used but not defined herein shall have the respective meanings given such terms in the Lease. This Workletter sets forth the terms and conditions relating to the construction of Tenant Improvements (defined below) in the Premises.

1.1Allowance. Tenant shall be entitled to an allowance (the “Tenant Improvement Allowance”) in an amount not to exceed $110.00 per square foot of Rentable Area of the Premises for the costs relating to the design, permitting and construction of Tenant’s improvements which will be permanently affixed to the Premises in accordance with this Workletter (the “Tenant Improvements”). In no event will Landlord be obligated to make disbursements pursuant to this Workletter in a total amount which exceeds the Tenant Improvement Allowance. Tenant agrees that it shall commence the Tenant Improvements promptly following the Commencement Date and diligently proceed to complete the same. Tenant must submit Payment Request Supporting Documentation (defined below) for such work in accordance with this Workletter no later than April 1, 2020, after which date Landlord’s obligation to fund such costs shall expire.

(a)Tenant Improvement Allowance Items. Except as otherwise set forth in this Workletter, the Tenant Improvement Allowance shall be disbursed by Landlord only for the following items and costs (collectively the “Tenant Improvement Allowance Items”):

(i)Payment of the fees of the Architect and the Building Consultants (as those terms are defined below) and payment of fees and costs reasonably incurred by Landlord for the review of the Construction Drawings (defined below) by Landlord or by Landlord’s third party consultants;

(ii)The payment of plan check, permit and license fees relating to the Tenant Improvements, including, without limitation, taxes, fees, charges and levies by governmental agencies;

(iii)The cost of construction of the Tenant Improvements, including, without limitation, costs and expenses for labor, materials, equipment and fixtures, after hours charges, testing and inspection costs, freight elevator usage, trash removal costs, any other services provided by third parties unaffiliated with Tenant in connection with the construction and contractors’ fees and general conditions;

(iv)The cost of any changes to the Building when such changes are required by the Construction Drawings, such cost to include all direct architectural and/or engineering fees and expenses incurred in connection therewith;

(v)The cost of any changes to the Construction Drawings (defined below) or Tenant Improvements required by applicable laws, including, without limitation, building codes (collectively, “Code”); and

(b)Disbursement of Tenant Improvement Allowance. During the design and construction of the Tenant Improvements, Landlord shall make periodic disbursements (no more often than once per month) of the Tenant Improvement Allowance to reimburse Tenant for Tenant Improvement Allowance Items and shall authorize the release of funds as follows.

(i)To request a periodic disbursement, Tenant shall deliver to Landlord: (A) a request for payment from Contractor (defined below) approved by Tenant, in a reasonable form to be provided or approved in advance by Landlord, including a schedule of values and showing the percentage of completion, by trade, of the Tenant Improvements, which details the portion of the work completed and the portion not completed; (B) invoices from all of Tenant’s Agents (defined below) for labor rendered and materials delivered to the Premises; (C) executed conditional mechanic’s lien releases from all of Tenant’s Agents who have lien rights with respect to the subject request for payment (along with unconditional mechanics’ lien releases with respect to payments made pursuant to Tenant’s prior submission hereunder) in compliance with all applicable laws; (D) if not already supplied to Landlord, a copy of the construction permits referenced in Section 3.2(a) below; and (E) all other information reasonably requested by Landlord (collectively, the “Payment Request Supporting Documentation”).

(ii)Within forty (40) days after Tenant’s delivery to Landlord of all Payment Request Supporting Documentation, Landlord shall deliver to Tenant payment in an amount equal to the lesser of: (x) the amount so requested by Tenant, as set forth in Section 1.2(b)(i) above, less (i) the applicable Over-Tenant Improvement Allowance Amount (defined in Section 3.2(a) below and (ii) a ten percent (10%) retention (the aggregate amount of such retentions to be known as the “Final Retention”), and (y) the balance of any remaining available portion of the Tenant Improvement Allowance (not including the Final Retention), provided that if Landlord, in good faith, disputes any item in a request for payment based on non-compliance of any work with the Approved Working Drawings (defined below) or due to any substandard work (reasonably determined by Landlord) and delivers a written objection to such item setting forth with reasonable particularity Landlord’s reasons for its dispute (a “Draw Dispute Notice”) within ten (10) days following Tenant’s submission of its Payment Request Supporting Documentation, Landlord may deduct the amount of such disputed item from the payment. Landlord and Tenant shall, in good faith, endeavor to diligently resolve any such dispute. Landlord’s payment of such amounts shall not be deemed Landlord’s approval or acceptance of the work furnished or materials supplied as set forth in Tenant’s payment request.

(iii)Subject to the provisions of this Work Agreement, following the final completion of construction of the Tenant Improvements, Landlord shall deliver to Tenant a check made payable to Tenant, or a check or checks made payable to another party or parties as reasonably requested by Tenant, in the amount of the Final Retention, provided that (A) Tenant delivers to Landlord properly executed unconditional mechanics’ lien releases from all of Tenant’s Agents in compliance with all applicable laws, as reasonably determined by Landlord; (B) Landlord has determined in good faith that no substandard work exists which adversely affects the mechanical, electrical, plumbing, heating, ventilating and air conditioning, life-safety or other systems of the Building, the curtain wall of the Building, the structure or exterior appearance of the Building; (C) Architect delivers to Landlord a certificate, in a form reasonably acceptable to Landlord, certifying that the construction of the Tenant Improvements has been finally completed; (D) Tenant supplies Landlord with evidence that all governmental approvals required for an occupant to legally occupy the Premises has been obtained; and (E) Tenant has fulfilled its Completion Obligations (defined below) and has otherwise complied with Landlord’s standard “close‑out” requirements regarding city approvals, closeout tasks, closeout documentation regarding the general contractor, financial close-out matters, and Tenant’s vendors.

2.1Selection of Architect; Construction Drawings. Tenant shall retain DGA Architects (the “Architect”) to prepare the Construction Drawings. Such approval shall be granted or denied within three (3) business days upon request, and Landlords’ failure to respond within such three (3) business day period shall be deemed approval by Landlord. Tenant shall retain engineering consultants approved in writing, in advance by Landlord, such approval not to be unreasonably withheld (the “Building Consultants”) to prepare all plans and engineering working drawings and perform all work relating to mechanical, electrical and plumbing (“MEP”), HVAC/Air Balancing, life-safety, structural, sprinkler and riser work. Landlord acknowledges its pre-approval of the following Building Consultants:

The plans and drawings to be prepared by Architect and the Building Consultants hereunder (i.e., both the Space Plan and the Working Drawings, as each term is defined below) shall be known collectively as the “Construction Drawings.” All Construction Drawings shall comply with the drawing format and specifications reasonably determined or approved by Landlord and shall be subject to Landlord’s prior written approval, not to be unreasonably withheld, conditioned or delayed. Such approval shall be granted or denied within ten (10) business days after delivery to Landlord, and Landlord’s failure to respond within such ten (10) business day period, if such failure continues following a second, five (5) business day notice, shall be deemed approval by Landlord. Any disapproval of the Construction Drawings shall accompany Landlord’s detailed reasons for such disapproval. All MEP drawings must be fully engineered and cannot be prepared on a “design-build” basis. Landlord’s review of the Construction Drawings shall be for its sole purpose and shall not obligate Landlord to review the same, for quality, design, Code compliance or other like matters. Accordingly, notwithstanding

that any Construction Drawings are reviewed by Landlord or its space planner, architect, engineers and consultants, and notwithstanding any advice or assistance which may be rendered to Tenant by Landlord or Landlord’s space planner, architect, engineers, and consultants, Landlord shall have no liability whatsoever in connection therewith and shall not be responsible for any omissions or errors contained in the Construction Drawings.

2.2Space Plan. Tenant shall supply Landlord for Landlord’s review and approval with four (4) copies signed by Tenant of its space plan for the Premises (the “Space Plan”) before any architectural working drawings or engineering drawings have been commenced. The Space Plan shall include a layout and designation of all laboratory facilities, offices, rooms and other partitioning, their intended use, and equipment to be contained therein. Landlord may request clarification or more specific drawings for special use items not included in the Space Plan. Landlord shall advise Tenant within five (5) business days after Landlord’s receipt of the Space Plan (or, if applicable, such additional information reasonably requested by Landlord pursuant to the provisions of the immediately preceding sentence) if the same is approved or is unsatisfactory or incomplete in any respect, and any disapproval of the Space Plan shall accompany Landlord’s detailed reasons for such disapproval. Upon any disapproval by Landlord, Tenant shall promptly cause the Space Plan to be revised to correct any deficiencies or other matters Landlord may reasonably require and deliver such revised Space Plan to Landlord. Landlord’s failure to respond within five (5) business days thereafter, if such failure continues following a second, three (3) business day notice, shall be deemed approval by Landlord.

2.3Working Drawings. After the Space Plan has been approved by Landlord, Tenant shall cause the Architect and the Engineers to promptly complete the architectural and engineering drawings, and Architect shall compile a fully coordinated set of drawings, including but not limited to architectural, structural, mechanical, electrical, plumbing, fire sprinkler and life safety in a form which is complete to allow subcontractors to bid on the work and to obtain all applicable permits (collectively, the “Working Drawings”) and shall submit the same to Landlord for Landlord’s review and approval (such approved Working Drawings, “Approved Working Drawings”). Tenant shall supply Landlord with four (4) copies signed by Tenant of the Working Drawings. Landlord shall advise Tenant within ten (10) business days after Landlord’s receipt of the Working Drawings if Landlord, in good faith, determines that the same are approved or are unsatisfactory or incomplete, and any disapproval of the Working Drawings shall accompany Landlord’s detailed reasons for such disapproval. If Tenant is so advised, Tenant shall promptly revise the Working Drawings to correct any deficiencies or other matters Landlord may reasonably require and deliver such revised Working Drawing to Landlord. Landlord’s failure to respond within five (5) business days thereafter, if such failure continues following a second, three (3) business day notice, shall be deemed approval by Landlord.

2.4Landlord’s Approval. Tenant acknowledges that it shall be deemed reasonable for Landlord to disapprove the Space Plan and any subsequent Working Drawings unless, at a minimum, the same are prepared on the basis that they will only utilize the appropriate pro-rated share of building systems capacity made available by Landlord for tenant usage in the building (including, but not limited to, the HVAC equipment, electrical power, fire sprinkler, emergency electrical power), (b) the Tenant Improvements as specified and designed comply with the requirements of the Project’s Sustainability Practices and the applicable Green Building Standards set forth in Exhibit B-1 attached hereto, and (c) the sprinkler systems shall be designed in

compliance with the specifications provided by FM Global. Additionally, Landlord’s approval of any matter under this Workletter may be withheld if Landlord reasonably determines that the same would violate any provision of the Lease or this Workletter or would adversely affect the mechanical, electrical, plumbing, heating, ventilating and air conditioning, life-safety or other systems of the Building, the curtain wall of the Building, the structure or exterior appearance of the Building.

2.5Changes to the Working Drawings. Any changes to the Approved Working Drawings (each, a “Change”) shall be requested and instituted in accordance with the provisions of this Section 2.5 and shall be subject to the written approval of the non-requesting party in accordance with this Workletter.

(a)Either Landlord or Tenant may request Changes after Landlord approves the Working Drawings by notifying the other party thereof 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 requested Changes, including (i) the Change, and (ii) any modification of the Approved Working Drawings, as applicable, necessitated by the Change. If the nature of a Change requires revisions to the Approved Working Drawings, then Tenant shall be solely responsible for the cost and expense of such revisions and any increases in the cost of the Tenant Improvements as a result of such Change. Change Requests shall be signed by the requesting party’s representative. Landlord shall only request a Change if it reasonably believes that such Change is necessary to comply with applicable Laws, to prevent a material adverse impact on the Building’s systems or to address a material Building structural issue.

(b)All Change Requests shall be subject to the other party’s prior written approval, which approval shall not be unreasonably withheld, conditioned or delayed. The non-requesting party shall have three (3) business days after receipt of a Change Request to notify the requesting party in writing of the non-requesting party’s decision either to approve or object to the Change Request. The non-requesting party’s failure to respond within such three (3) business day period shall be deemed approval by the non-requesting party.

(a)The Contractor. Tenant will retain Dome Construction as a general contractor to construct the Tenant Improvements (“Contractor”).

(b)Tenant’s Agents. A list of all subcontractors, laborers, materialmen, and suppliers used by Tenant (such subcontractors, laborers, materialmen, and suppliers, and the Contractor to be known collectively as “Tenant’s Agents”) must be provided to Landlord, provided that Landlord will require Tenant to retain the Building Consultants. Tenant shall contract with Landlord’s base building subcontractors for any mechanical, electrical, plumbing, life safety, structural or HVAC work in the Premises. All of Tenant’s Agents shall be licensed in the State of California, capable of being bonded and union-affiliated in compliance with all then existing master labor agreements.

(a)Construction Contract. Prior to Tenant’s execution of the construction contract and general conditions with Contractor (the “Contract”), Tenant shall submit the Contract to Landlord for its approval, which approval shall not be unreasonably withheld, conditioned or delayed. Landlord shall have three (3) business days upon receipt of the Contract to either grant or deny its approval, and Landlord’s failure to respond within such three (3) business day period shall be deemed approval by Landlord. Prior to the commencement of the construction of the Tenant Improvements, Tenant shall provide Landlord with a schedule of values consisting of a detailed breakdown, by trade, of the final costs to be incurred or which have been incurred, for all Tenant Improvement Allowance Items in connection with the design and construction of the Tenant Improvements, which costs form the basis for the amount of the Contract (“Final Costs”). Prior to the commencement of construction of the Tenant Improvements, Landlord and Tenant shall identify the amount equal to the difference between the amount of the Final Costs and the amount of the Tenant Improvement Allowance (less any portion thereof already disbursed by Landlord, or in the process of being disbursed by Landlord, on or before the commencement of construction of the Tenant Improvements), the "Over-Allowance Amount", and Landlord will reimburse Tenant on a monthly basis, as described in Section 1.2(b)(ii) above, for a percentage of each amount requested by the Contractor or otherwise to be disbursed under this Workletter, which percentage shall be equal to the Tenant Improvement Allowance divided by the amount of the Final Costs (after deducting from the Final Costs any amounts expended in connection with the preparation of the Construction Drawings, and the cost of all other Tenant Improvement Allowance Items incurred prior to the commencement of construction of the Tenant Improvements), and Tenant shall be solely responsible for any Over-Allowance Amount. If, after the Final Costs have been initially determined, the costs relating to the design and construction of the Tenant Improvements shall change, any additional costs for such design and construction in excess of the Final Costs shall be added to the Over-Allowance Amount and the Final Costs, and Landlord’s reimbursement percentage, shall be recalculated in accordance with the terms of the immediately preceding sentence. Notwithstanding anything set forth herein to the contrary, construction of the Tenant Improvements shall not commence until Tenant has procured and delivered to Landlord a copy of all permits necessary for commencement of construction of the Tenant Improvements.

(i)Landlord’s General Conditions for Tenant’s Agents and Tenant Improvement Work. Construction of the Tenant Improvements shall comply with the following: (A) the Tenant Improvements shall be constructed in strict accordance with the Approved Working Drawings and Landlord’s then-current published construction guidelines; (B) Tenant’s Agents shall submit schedules of all work relating to the Tenant Improvements to Landlord and Landlord shall, within five (5) business days of receipt thereof, inform Tenant’s Agents of any changes which are necessary thereto, and Tenant’s Agents shall adhere to such corrected schedule; and (C) Tenant shall abide by all reasonable and non-discriminatory rules made and provided to Tenant in writing by Landlord’s Building manager with respect to the use of contractor parking, materials delivery, freight, loading dock and service elevators, any required shutdown of utilities (including life-safety systems), storage of materials, coordination of work with the contractors of Landlord, and any other matter in connection with this Workletter, including, without limitation, the construction of the Tenant Improvements, provided that such rules shall not include additional charge for the use of freight, loading dock and service elevators or storage of materials. Tenant shall pay an oversight and supervisory fee (the “Coordination Fee”) to Landlord in an amount equal to one percent (1.0%) of the Final Costs.

(ii)Indemnity. Tenant’s indemnity of Landlord as set forth in the Lease shall also apply with respect to any and all costs, losses, damages, injuries and liabilities related in any way to any act or omission of Tenant or Tenant’s Agents, or anyone directly or indirectly employed by any of them, or in connection with Tenant’s non-payment of any amount arising out of the Tenant Improvements and/or Tenant’s disapproval of all or any portion of any request for payment. Such indemnity by Tenant, as set forth in the Lease, shall also apply with respect to any and all costs, losses, damages, injuries and liabilities related in any way to Landlord’s performance of any ministerial acts reasonably necessary (A) to permit Tenant to complete the Tenant Improvements, and (B) to enable Tenant to obtain any related building permit or certificate of occupancy; provided, however, nothing contained in this Workletter shall be deemed to indemnify Landlord from or against liability caused solely by Landlord’s negligence or willful misconduct.

(iii)Requirements of Tenant’s Agents. Each of Tenant’s Agents shall guarantee to Tenant and for the benefit of Landlord that the portion of the Tenant Improvements for which it is responsible shall be free from any defects in workmanship and materials for a period of not less than one (1) year from the date of completion thereof. Each of Tenant’s Agents shall be responsible for the replacement or repair, without additional charge, of all work done or furnished in accordance with its contract that shall become defective within one (1) year after the completion of the work performed by such contractor or subcontractor. The correction of such work shall include, without additional charge, all additional expenses and damages incurred in connection with the removal or replacement of all or any part of the Tenant Improvements, and/or the Building and/or common areas that are damaged or disturbed thereby. All such warranties or guarantees as to materials or workmanship of or with respect to the Tenant Improvements shall be contained in the Contract or subcontract and shall be written such that such guarantees or warranties shall inure to the benefit of both Landlord and Tenant, as their respective interests may appear, and can be directly enforced by either. Tenant covenants to give to Landlord any assignment or other assurances as may be necessary to effect such right of direct enforcement.

(i)General Coverages. All of Tenant’s Agents shall carry employer’s liability and worker’s compensation insurance covering all of their respective employees, and shall also carry commercial general liability insurance, including personal and bodily injury, property damage and completed operations liability, all with limits, in form and with companies as are required to be carried by Tenant as set forth in the Lease.

(ii)Special Coverages. Tenant or Contractor shall carry “Builder’s All Risk” insurance in an amount approved by Landlord covering the construction of the Tenant Improvements, and such other insurance as Landlord may require, it being understood and agreed that the Tenant Improvements shall be insured by Tenant pursuant to the Lease immediately upon completion thereof. Such insurance shall be in amounts and shall include such extended coverage endorsements as may be reasonably required by Landlord, and shall be in form and with companies as are required to be carried by Tenant as set forth in the Lease.

(iii)General Terms. Certificates for all of the foregoing insurance coverage shall be delivered to Landlord before the commencement of construction of the Tenant Improvements and before the Contractor’s equipment is moved onto the site. All such policies of insurance must contain a provision that the company writing said policy will endeavor to give Landlord thirty (30) days’ prior written notice of any cancellation of such insurance. In the event that the Tenant Improvements are damaged by any cause during the course of the construction thereof, Tenant shall immediately repair the same at Tenant’s sole cost and expense. Tenant’s Agents shall maintain all of the foregoing insurance coverage in force until the Tenant Improvements are fully completed and accepted by Landlord, except for any Products and Completed Operations Coverage insurance required by Landlord, which is to be maintained for one (1) year following completion of the work and acceptance by Landlord and Tenant. All policies carried hereunder shall insure Landlord, Wareham Property Group as Landlord’s manager, and Tenant, as their interests may appear, as well as Tenant’s Agents. All insurance, except Workers’ Compensation, maintained by Tenant’s Agents shall preclude subrogation claims by the insurer against anyone insured thereunder. Such insurance shall provide that it is primary insurance as respects Landlord and Tenant and that any other insurance maintained by Landlord or Tenant is excess and noncontributing with the insurance required hereunder. The requirements for the foregoing insurance shall not derogate from the provisions for indemnification of Landlord by Tenant under the Lease and/or this Workletter.

(d)Governmental Compliance. The Tenant Improvements shall comply in all respects with the following: (i) the Code and other applicable federal, state, city and/or quasi-governmental laws, codes, ordinances and regulations, as each may apply according to the rulings of the controlling public official, agent or other person or entity; (ii) applicable standards of the American Insurance Association (formerly, the National Board of Fire Underwriters) and the National Electrical Code; (iii) building material manufacturer’s specifications, and (iv) the Project’s Sustainability Practices and the applicable Green Building Standards as set forth in Exhibit B-1.

(e)Inspection by Landlord. Landlord shall have the right to inspect the Tenant Improvements during normal business hours upon no less than 48 hours’ advance notice, provided however, that Landlord’s failure to inspect the Tenant Improvements shall in no event constitute a waiver of any of Landlord’s rights hereunder nor shall Landlord’s inspection of the Tenant Improvements constitute Landlord’s approval of the same. Should Landlord disapprove any portion of the Tenant Improvements, Landlord shall notify Tenant in writing of such disapproval and shall specify the items disapproved and the reasons therefor. Any defects or deviations in, and/or disapproval by Landlord of, the Tenant Improvements shall be rectified by Tenant at no expense to Landlord, provided however, that in the event Landlord determines that a defect or deviation exists or disapproves of any matter in connection with any portion of the Tenant Improvements and such defect, deviation or matter might adversely affect the mechanical, electrical, plumbing, heating, ventilating and air conditioning or life-safety systems of the Building, the structure or exterior appearance of the Building or any other tenant’s use of such other tenant’s leased premises, and Tenant fails to commence to remedy the same within thirty (30) days after Landlord’s written notice thereof or Tenant fails to diligently execute the same to completion, Landlord may take such action as Landlord deems necessary, at Tenant’s expense and without incurring any liability on Landlord’s part, to correct any such defect, deviation and/or matter, including, without limitation, causing the cessation of performance of the construction of the Tenant Improvements until such time as the defect, deviation and/or matter is corrected to Landlord’s reasonable satisfaction.

(f)Meetings. Tenant shall hold periodic meetings at a reasonable time with the Architect and the Contractor regarding the progress of the preparation of the Construction Drawings and the construction of the Tenant Improvements, which meetings shall be held at the Premises (unless otherwise notified by Tenant to Landlord), and Landlord and/or its agents shall receive prior written notice of, and shall have the right to attend, all such meetings. Upon Landlord’s reasonable request, certain of Tenant’s Agents shall attend such meetings. In addition, minutes shall be taken at all such meetings, and Landlord will be included in the distribution list for such minutes. One such meeting each month shall include the review of Contractor’s current request for payment.

3.3Notice of Completion; Copy of Record Set of Plans. Following completion of construction of the Tenant Improvements, Landlord shall cause a Notice of Completion to be recorded in the office of the Recorder of Alameda County and shall furnish a copy thereof to Tenant. Within thirty (30) days following the completion of construction, (i) Tenant shall cause the Architect and Contractor (A) to update the Approved Working Drawings as necessary to reflect all changes made to the Approved Working Drawings during the course of construction, (B) to certify to the best of their knowledge that the updated drawings are true and correct, which certification shall survive the expiration or termination of the Lease, and (C) to deliver to Landlord such updated drawings in accordance with Landlord’s then-current CAD Requirements within ninety (90) days following issuance of a certificate of occupancy for the Premises, and (ii) Tenant shall deliver to Landlord a copy of all warranties, guaranties, and operating manuals and information relating to the improvements, equipment, and systems in the Premises. Tenant’s obligations set forth in this Section are collectively referred to as the “Completion Obligations.”

5.3Tenant’s Default. Notwithstanding any provision to the contrary contained in the Lease, if a Default by Tenant under the Lease (including, without limitation, this Workletter) has occurred and is continuing at any time on or before the substantial completion of the Tenant Improvements, then in addition to all other rights and remedies granted to Landlord pursuant to the Lease, Landlord shall have the right to withhold payment of all or any portion of the Tenant Improvement Allowance until such time as such Default is cured pursuant to the terms of the Lease.

Tenant shall cause the Architect, Engineers and General Contractor (the Tenant’s “TI Project Team”) to rate the proposed Tenant Improvements on a “LEED” scorecard with a goal of achieving at least a “Gold” level as set forth by the USGBC, and shall provide that information, attested to by TI Project Team as part of the Space Plan and Working Drawings approval process.

Tenant agrees to direct the Architect and Engineers to design the Tenant Improvements such that they meet the following standards:

Landlord-provided 1.5 MW 60Hz 480V diesel standby emergency generator at grade at building exterior. Generator is sized for 2400A. Two Automatic Transfer Switches (ATS) divide life safety loads from tenant discretionary loads. 800A is allocated for life safety purposes and 1600 A for tenant discretionary loads. Off this riser each floor has a 200A emergency panel (rated 277/480V, 3-phase, 4 wire) to which tenants have their pro-rata access.
