00066513.5	8

subsequent calendar year. There shall be included in Taxes for any year falling within the Tern 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 to the extent falling with the Term.

(1) The Extension Option shall be upon the same material terms and conditions contained in this Lease, except that (i) the initial Monthly Base Rent for the Premises shall be equal to the fair market rent for the Premises determined in the manner set forth in Section 2.2(b)(3) below, (ii) on each anniversary of the commencement date of the Extended Term, the Monthly Base Rent shall increase three and one-half percent (3½%), on a cumulative basis, and (iii) Tenant shall accept the Premises in an “as is” condition without any obligation of Landlord to repaint, remodel, repair, improve or alter the Premises (subject, however, to the terms of Section 8.1 of the Lease).

(2) Tenant’s election to exercise the Extension Option must be given to Landlord in writing no less than three hundred and sixty-five (365) days prior to the expiration of the Initial Term (the “Extension Notice”). Within thirty (30) days of Landlord’s receipt of the Extension Notice, Landlord shall send Tenant written notice of Landlord’s good faith determination of the Fair Market Rent for the Premises (the “Fair Market Rent Notice”). For purposes of this Section, the term “Fair Market Rent” shall mean the base rental rate, periodic rental rate adjustment and other charges and increases, if any, for space comparable in size, location and quality to the Premises under a primary lease (and not sublease) to new or renewing tenants, for a comparable term with a tenant improvement allowance, if applicable and taking into consideration such amenities as existing improvements, view, floor on which the Premises are situated and the like, situated in buildings in Berkeley and Emeryville, California. Notwithstanding anything to the contrary contained herein, the Extension Option shall automatically terminate and be of no further force or effect, whether or not Tenant has timely exercised the Extension Option, if a monetary Default or material non-monetary Default exists at the time of exercise of the Extension Option or at the time of commencement of the Extended Term.

(3) If Tenant properly exercises the Extension Option, the Monthly Base Rent during the Extended Term shall be determined in the following manner. The Monthly Base Rent as of the commencement of the Extended Term shall be adjusted to an amount equal to the Fair Market Rent for the Premises as specified in the Fair Market Rent Notice, subject to Tenant’s right of arbitration as set forth below. Notwithstanding the above, under no circumstances will the Monthly Base Rent during the first twelve (12) months of the Extension Term be less than the Monthly Base Rent for the last month of the Initial Term. If Tenant believes that the Fair Market Rent specified in the Fair Market Rent Notice exceeds the actual Fair Market Rent for the Premises as of the date of such notice, then Tenant shall so notify Landlord within ten (10) days of Tenant’s receipt of the Fair Market Rent Notice. If Tenant fails to so notify Landlord within such 10-day


00066513.5	11

period, Landlord’s determination of the Fair Market Rent shall be final and binding upon the parties. If the parties are unable to agree upon the Fair Market Rent within ten (10) days after Landlord’s receipt of Tenant’s objection to the Fair Market Rent Notice, the amount of Monthly Base Rent as of the commencement of the Extended Term shall be determined as follows:

(i) Within twenty (20) days after the 10-day period has expired and the parties have failed to agree on the Fair Market Rent, Tenant, at its sole expense, shall obtain and deliver in writing to Landlord a determination of the Fair Market Rent for the Premises for a term equal to the Extended Term from a broker (“Tenant’s Broker”) licensed in the State of California and engaged in the laboratory brokerage business in Berkeley/Emeryville, California, for at least the immediately preceding five (5) years. If Landlord accepts such determination, the Monthly Base Rent for the Extended Term shall be adjusted to an amount equal to the amount determined by Tenant’s Broker.

(ii) If Landlord does not accept such determination, within fifteen (15) days after receipt of the determination of Tenant’s broker, Landlord shall designate a broker (“Landlord’s Broker”) licensed in the State of California and engaged in the laboratory brokerage business in Berkeley/Emeryville, California, for at least the immediately preceding five (5) years. Landlord’s Broker and Tenant’s Broker shall name a third broker, similarly qualified, within five (5) days after appointment of Landlord’s Broker. Landlord’s Broker and Tenant’s Broker shall each determine the Fair Market Rent for the Premises as of the commencement of the Extended Term for a term equal to the Extended Term within fifteen (15) days after the appointment of the third broker. The Monthly Base Rent payable by Tenant effective as of the commencement of the Extended Term shall be adjusted to an amount equal to the determination of Fair Market Rent made by either Landlord’s Broker or Tenant’s Broker that the third broker finds to be closer to the Fair Market Rent.

(iii) 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 any third broker shall be paid one-half by Landlord and one-half by Tenant.

(4) If the amount of the Fair Market Rent is not known as of the commencement of the Extended Term, then Tenant shall continue to pay the Monthly Base Rent for the Premises in effect at the expiration of the Extended Term until the amount of the Fair Market Rent is determined. When such determination is made, Tenant shall pay any deficiency to Landlord upon demand.

(5) In connection with the extension of the Term pursuant to Tenant’s exercise of the Extension Option, the parties acknowledge and agree that Landlord shall not be responsible for the payment to any real estate broker, salesperson or finder claiming to have represented Tenant of any commission, finder’s fee or other compensation in connection with or as a consequence of Tenant’s exercise of the Extension Option.

(6) Notwithstanding anything to the contrary contained herein, Tenant’s rights under this Section 2.2(b) are personal to the original Tenant executing this Lease or a Permitted Transferee to whom this Lease is assigned (“Named Tenant”) and shall not be assigned or


00066513.5	12

assignable, in whole or in part, to any third party other than a Permitted Transferee. Any assignment or other transfer of such rights by Named Tenant in violation of the preceding sentence shall be void and of no force or effect. Without limiting the generality of the foregoing, no sublessee of the Premises shall be permitted to exercise the rights granted to Tenant under this Section 2.2(b).

2.3 FAILURE TO DELIVER POSSESSION

If the Premises are not delivered to Tenant by the Commencement Date for any reason, Landlord shall not be liable for any claims, damages or liabilities by reason thereof, nor affect the validity of this Lease or the obligations of Tenant hereunder. Notwithstanding the foregoing to the contrary, if Landlord is unable to deliver the Premises by the date (the “Outside Delivery Date”) that is thirty (30) days after the Commencement Date (which Outside Delivery Date shall be subject to extension day-for-day for Force Majeure events), then Tenant may, at its option, by notice in writing (the “Termination Notice”) within thirty (30) days after the Outside Delivery Date cancel this Lease, in which event Landlord and Tenant shall be discharged from all obligations hereunder, and Landlord shall return to Tenant any prepaid rent and the Security Deposit, and both parties shall be released from all obligations under this (excepting only those obligations, such as indemnification and defense obligations, which are expressly intended to survive the termination of this Lease). If the Termination Notice is not received by Landlord within said thirty (30) day period, Tenant’s right to cancel this Lease shall terminate. The remedy set forth above shall be Tenant’s sole remedy in the event of a delay in delivering possession of the Premises to Tenant. In no event shall Landlord be liable for special or consequential damages as a result of any such delay.

2.4 CONDITION OF PREMISES

Tenant shall be conclusively deemed to have accepted the Premises “AS IS” in the condition existing on the date Tenant first takes possession, and to have waived all claims relating to the condition of the Premises. 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. Nothing in this Section 2.4 shall be deemed to relieve Landlord from any of its duties or obligations expressly set forth in this Lease.

2.5 PARKING

During the Term, Tenant may use the number of spaces specified in Section 1.1 for parking at the standard prevailing monthly rates being charged from time to time by Landlord or its parking operator without regard to discounts provided to any other occupants of the Campus, except as set forth below. The standard rate is $135.00 per space, per month, as of the date of this Lease; provided, however, that 4 of the spaces specified in Section 1.1 shall remain at the rate of $61.00 through December 31, 2025. In the event Tenant fails at any time to pay the full amount of such parking charges, until the delinquent amount is paid Tenant’s parking rights may be reduced to the extent of Tenant’s failure to pay for any such parking. The locations and type of parking (including, without limitation, valet parking, if any) shall be designated by Landlord or Landlord’s parking operator from time to time. Tenant acknowledges and agrees that the parking spaces


00066513.5	13

serving the Project may include tandem or valet parking and a mixture of spaces for compact vehicles as well as full-size passenger automobiles, and that Tenant shall not use parking spaces for vehicles larger than the striped size of the parking spaces. All vehicles utilizing Tenant’s parking spaces 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. Tenant shall comply with any and all 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 spaces. Tenant shall not allow any vehicles using Tenant’s parking spaces to be parked, loaded or unloaded except in accordance with this Section, including in the areas and in the manner 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.

Article 3
RENT

From and after the Rent Commencement Date, 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, without any prior demand therefor in immediately available funds and without any deduction or offset whatsoever (except as expressly provided herein), 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 or prior to 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 Tenant’s execution of this Lease. Monthly Base Rent shall be prorated for partial months within the Term. Tenant’s covenant to pay Rent shall be independent of every other covenant in this Lease.

Article 4
RENT ADJUSTMENTS AND PAYMENTS

4.1 RENT ADJUSTMENTS

(a) From and after the Rent Commencement Date until the Termination 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 Rent Commencement Date and the Termination Date occur) as follows:

(1) 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;


00066513.5	14

(2) 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; and

(3) 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 calendar year (or partial calendar year) shall be Tenant’s Share of Operating Expenses for such calendar year (or partial calendar year) and Tenant’s Share of Taxes for such calendar year (or partial calendar year).

(b) On or before the beginning of each calendar year or with Landlord’s Statement (as defined in Section 4.2 below), Landlord may estimate and notify Tenant in writing of its estimate of the amount of Operating Expenses and Taxes payable by Tenant for such calendar year. Prior to the first determination by Landlord of the amount of Operating Expenses and Taxes for the first calendar year, Landlord may estimate such amounts in the foregoing calculation. Landlord shall have the right from time to time but not more than once 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 but not more than once during any calendar year throughout the Term.

(c) 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. In addition, Landlord shall have the right, at its sole discretion, from time to time, to equitably allocate certain Operating Expenses among only certain tenants of the Project as to any expense or cost that relates to a repair, replacement or service that benefits only those tenants, and the Rent Adjustments shall reflect any such allocations.

4.2 STATEMENT OF LANDLORD

As soon as practical after the expiration of each calendar year, Landlord will furnish Tenant with a statement respecting the prior calendar year (“Landlord’s Statement”) showing the following:

(a) The amount of actual Operating Expenses and Taxes for such calendar year;

(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.


00066513.5	15

Tenant shall pay to Landlord within ten (10) days after receipt of such statement any amounts for Rent Adjustments then due in accordance with Landlord’s Statement. Any amounts due from Landlord to Tenant pursuant to this Section shall be credited to the Rent Adjustment Deposit next coming due, or promptly refunded to Tenant if the Term has already expired or terminated, 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, unless Landlord fails to deliver such Landlord’s Statement as to Operating Expenses or Taxes (unless such delivery delay as to Taxes is due to a delay in the taxing authority providing updated Tax information) within twenty-four (24) months following the conclusion of the applicable calendar year. 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 during any partial calendar year in which this Lease expires or terminates, Landlord may include in the Rent Adjustment Deposit its estimate of Rent Adjustments which might not be finally determined until after the expiration or termination of this Lease. Tenant’s obligation to pay Rent Adjustments survives the expiration or termination of this Lease.

4.3 BOOKS AND RECORDS

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 sixty (60) days following the date upon which Landlord’s Statement is delivered to Tenant, to examine 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 the examination reveals an overcharge of five percent (5%) or more, then Landlord shall pay for all reasonable and actual third-party costs of such examination, up to a maximum amount of the lesser of the amount of the overcharge or Five Thousand Dollars ($5,000.00). If Tenant performs such examination, but does not object in writing to Landlord’s Statement within ninety (90) days after 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 Landlord’s Statement, Tenant shall 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 unless Tenant has paid and continues to pay all Rent when due. Upon resolution of any dispute with respect to Operating Expenses and Taxes, Tenant


00066513.5	16

shall either pay Landlord any shortfall or Landlord shall credit Tenant with respect to any overages paid by Tenant within thirty (30) days after such determination. The records obtained by Tenant shall be treated as confidential and neither Tenant nor any of its representatives or agents shall disclose or discuss the information set forth in the audit to or with any other person or entity except (a) to or with Tenant’s directors, officers, attorneys, accountants, auditors, financial advisors, investors, employees and consultants; or (b) as required by Law or legal process (the “Confidentiality Requirement”). Tenant shall indemnify and hold Landlord harmless for any losses or damages arising out of the breach of the Confidentiality Requirement.

4.4 TENANT OR LEASE SPECIFIC TAXES

In addition to Monthly Base Rent, Rent Adjustments, Rent Adjustment Deposits and other charges to be paid by Tenant, Tenant shall pay to Landlord, upon demand, any and all taxes payable by Landlord (other than Excluded 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 Tenant Work or Tenant Alterations, whether title thereto is in Landlord or Tenant; or (e) upon this transaction. Taxes or supplemental 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, but the standard property management fees shall apply to any such payments.

Article 5
SECURITY

(a) Simultaneously with Tenant’s execution and delivery of this Lease to Landlord, Tenant shall pay Landlord in immediately available funds the cash amount of the Security Deposit set forth in Section 1.1(11) of this Lease, which Security Deposit Landlord shall hold under this Lease for the full and faithful performance by Tenant of each and every term, provision, covenant, and condition of this Lease. If Tenant fails to perform any of the terms, provisions, covenants and conditions of this Lease or any other document executed by Tenant in connection with this Lease beyond any applicable notice or cure period, then Landlord may use, apply, or retain the whole or any part of the Security Deposit for the payment of any Rent not paid when due, for the cost of repairing any damage, for the cost of cleaning the Premises, for the payment of any other sum which Landlord may expend or may be required to expend by reason of Tenant’s failure to perform, and otherwise for compensation of Landlord for any other loss or damage to Landlord occasioned by Tenant’s failure to perform, including, but not limited to, any loss of future Rent and any damage or deficiency in the reletting of the Premises (whether such loss, damages or deficiency accrue before or after summary proceedings or other reentry by Landlord) and the amount of the unpaid past Rent, future Rent loss, and all other losses, costs and damages, that Landlord would be entitled to recover if Landlord were to pursue recovery under Section 11.2(b)


00066513.5	17

or (c) of this Lease or California Civil Code Section 1951.2 or 1951.4 (and any supplements, amendments, replacements and substitutions thereof and therefor from time to time). If Landlord so uses, applies or retains all or part of the Security Deposit, Tenant shall within five (5) Business Days after demand pay or deliver to Landlord in immediately available funds the sum necessary to replace the amount used, applied or retained. The Security Deposit (except any amount retained for application by Landlord as provided herein) shall be returned to Tenant within thirty (30) days after the later of: (i) the Termination Date or (ii) recovery of possession of the Premises by Landlord in accordance with this Lease (including, without limitation, Sections 6.4, 6.7, 9.3 and 12.2 of this Lease); provided, however, in no event shall any such return be construed as an admission by Landlord that Tenant has performed all of its obligations hereunder.

(b) The Security Deposit shall not be deemed an advance rent deposit or an advance payment of any kind, or a measure of Landlord’s damages with respect to Tenant’s failure to perform, nor shall any action or inaction of Landlord with respect to it or its use or application be a waiver of, or bar or defense to, enforcement of any right or remedy of Landlord. Landlord shall not be required to keep the Security Deposit separate from its general funds and shall not have any fiduciary duties or other duties (except as set forth in this Section) concerning the Security Deposit. Tenant shall not be entitled to any interest on the Security Deposit. In the event of any sale or other transfer of Landlord’s interest in the Building, Landlord shall have the right to transfer the Security Deposit, or balance thereof, to the transferee and any such transfer shall release Landlord from all liability for the return of the Security Deposit if the Security Deposit is actually transferred to the purchaser of Landlord’s interest in the Building and such purchaser assumes Landlord’s obligations under this Article 5. Tenant thereafter shall look solely to such transferee for the return or payment of the Security Deposit. Tenant shall not assign or encumber or attempt to assign or encumber the Security Deposit or any interest in it and Landlord shall not be bound by any such assignment, encumbrance, attempted assignment or attempted encumbrance, and regardless of one or more assignments of this Lease, Landlord may return the Security Deposit to the original Tenant without liability to any assignee. Tenant hereby waives any and all rights of Tenant under the provisions of Section 1950.7 of the California Civil Code, and any and all rights of Tenant under all provisions of Law, now or hereafter enacted, regarding security deposits.

Article 6
SERVICES

6.1 LANDLORD’S GENERAL SERVICES

(a) Landlord shall furnish the following services the cost of which services shall be included in Operating Expenses or paid directly by Tenant to the 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 outside of Standard Operating Hours, HVAC shall be set to minimum safe setback levels for laboratory operations, subject to compliance with all applicable voluntary and mandatory regulations and Laws;


00066513.5	18

(2) tempered and cold water for normal and customary use in the Premises 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; and

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

(b) Landlord shall provide a security program for the Building (but not individually for Tenant or the Premises), the cost of which 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) If Tenant uses heat generating machines or equipment in the Premises to an extent which adversely affects the temperature otherwise maintained by the air-cooling system or whenever the occupancy or electrical load adversely affects the temperature otherwise maintained by the air-cooling system, Landlord reserves the right to install or to require Tenant to install supplementary air-conditioning units in the Premises. Tenant shall bear all costs and expenses related to the installation, maintenance and operation of such units.

(d) Tenant shall pay Landlord at rates fixed by Landlord for all tenants in the Project, charges for all water furnished to the Premises beyond that described in Section 6.1(a)(2) (if any), including the expenses of installation of a water line, meter and fixtures.

6.2 UTILITIES AND JANITORIAL SERVICES

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 on the terms provided in the definition of Operating Expenses set forth above. All utility services used by Tenant within the Premises, including, without limitation, electricity and gas, shall be paid for by Tenant either through a separate charge or as part of Operating Expenses. Such charges shall be based upon Tenant’s usage, which usage: (a) as to electricity, other than overhead lighting, shall be measured by a separate meter or sub-meter to be installed as part of the Tenant Work, and paid by Tenant within fifteen (15) days after billing as additional Rent under this Lease; and (b) as to all other utilities, shall either be reasonably estimated by Landlord and paid by Tenant within fifteen (15) days after billing as additional Rent under this Lease or included in Operating Expenses. 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


00066513.5	19

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 the Premises, 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 in the Premises 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.

6.3 ADDITIONAL AND AFTER HOUR SERVICES

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, as additional Rent under this Lease. Without limiting the generality of the foregoing, for HVAC service outside of Standard Operating Hours, Landlord’s prevailing rate as of the date of this Lease includes a one (1) hour minimum per activation. If Tenant shall fail to make any such payment, Landlord may, upon notice to Tenant and in addition to Landlord’s other remedies under this Lease, discontinue any or all of such additional services.

6.4 TELEPHONE SERVICES

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 Cables and the work in connection therewith shall be performed by contractors approved by Landlord and shall be subject to the direction of Landlord, except that such approval is not required as to Tenant’s telephone equipment (including Cables) within the Premises and from the Premises in a route designated by Landlord to any telephone cabinet or panel provided (as existing) within the Building for Tenant’s connection to the Cables serving the Building so long as Tenant’s equipment does not require connections different than or additional to those to the telephone cabinet or panel provided. Except to the extent of such Cables within the Premises or from the Premises to such telephone cabinet or panel, Landlord reserves the right to designate and control the entity or entities providing Cable installation, removal, repair and maintenance in the Building and to restrict and control access to telephone cabinets or panels. In the event Landlord designates a particular vendor or vendors to provide such Cable installation, removal, repair and maintenance for the Building, Tenant agrees to abide by and participate in such program. Tenant shall be responsible for and shall pay, as additional Rent under this Lease, all costs incurred in connection with the installation of Cables in the Premises, including any hook-up, access and maintenance fees related to the installation of such Cables in the Premises and the commencement of service therein, and the maintenance thereafter of such 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 Cables 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 Cables in the Premises and such failure affects or interferes with the operation or maintenance of


00066513.5	20

any other Cables serving the Building, Landlord or any vendor hired by Landlord may enter into and upon the Premises forthwith and perform such repairs, restorations or alterations as Landlord deems necessary in order to eliminate any such interference (and Landlord may recover from Tenant all of Landlord’s costs in connection therewith). If required by Landlord, no later than the Termination Date Tenant shall remove all Cables installed by Tenant for and during Tenant’s occupancy. Tenant agrees that neither Landlord nor any of its agents or employees shall be liable to Tenant, or any of Tenant’s employees, agents, customers or invitees or anyone claiming through, by or under Tenant, for any damages, injuries, losses, expenses, claims or causes of action because of any interruption, diminution, delay or discontinuance at any time for any reason in the furnishing of any telephone or other communication service to the Premises and the Building.

6.5 DELAYS IN FURNISHING SERVICES

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 , except as otherwise provided in this Section 6.5. 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. 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. Notwithstanding anything to the contrary in the foregoing, if Tenant is unable to use the Premises as a result of an interruption in service, and if any such interruption (i) continues for five (5) consecutive Business Days following Tenant’s delivery to Landlord of notice of such interruption, (ii) is caused by the negligence of Landlord or any of its agents, employees, contractors, vendors or licensees, and the cure of same is within the reasonable control of Landlord (and is not attributable to any acts or omissions of Tenant or any third party or to Force Majeure), (iii) materially and adversely affects Tenant’s ability to conduct business in the Premises, or any material portion thereof, and (iv) on account of such interruption Tenant ceases doing business in the Premises, Rent shall thereafter xxxxx to the extent the Premises are rendered unusable and are actually not used by Tenant as a result thereof, commencing on the sixth (6th) Business Day following Tenant’s notice hereunder and continuing for the remainder of the interruption. Tenant hereby waives any benefits of any applicable existing or future Law, including the provisions of California Civil Code section 1932(1), permitting the termination of this Lease due to such interruption, failure or inability.

(14) 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 or valid 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 the Permitted 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


00066513.5	33

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 7.1(f) 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, Hazardous Materials Laws or other Laws.

(16) 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.

7.2 LANDLORD ACCESS TO PREMISES; APPROVALS

may enter the Premises without rendering Landlord or its agents liable therefor, and without relieving Tenant of any obligations under this Lease.

(c) Landlord may enter the Premises for the purpose of conducting such inspections, tests and studies as Landlord may deem desirable or necessary to confirm Tenant’s compliance with all Laws and 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.

(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.

7.3 QUIET ENJOYMENT

Landlord covenants, in lieu of any implied covenant of quiet enjoyment, that so long as Tenant is Tenant is not in default under this Lease beyond the expiration of any notice, grace or cure period, 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.

7.4 TRANSPORTATION DEMAND MANAGEMENT PROGRAM

(a) 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 may require tenants of the Project 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:

9.1 TENANT ALTERATIONS

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

(1) Tenant shall not, except as provided herein, without the prior written consent of Landlord, which consent shall not be unreasonably withheld, make or cause to be made any Tenant Alterations in or to the Premises or any Property systems serving the Premises. Prior to making any Tenant Alterations, Tenant shall give Landlord ten (10) days prior written notice (or such earlier notice as would be necessary pursuant to applicable Law) to permit Landlord sufficient time to post appropriate notices of non-responsibility.

The contractors, mechanics and engineers who may be used are further limited to those whose work will not cause or threaten to cause disharmony or interference with Landlord or its 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


00066513.5	37

commencement of any work or delivery of materials to the Premises related to the Tenant Alterations such of the following as specified by Landlord: architectural plans and specifications, opinions from Landlord’s engineers stating that the Tenant Alterations will not in any way adversely affect the Building’s systems, necessary permits and licenses, certificates of insurance, and such other documents in such form reasonably requested by Landlord. 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. Upon completion of the Tenant Alterations, Tenant shall deliver to Landlord an as-built digitized set of plans and specifications for the Tenant Alterations in both protected document (“.pdf”) and computer-aided design (“CAD”) formats.

(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. Tenant is strongly encouraged to 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) For any Tenant Alterations which Tenant requests Landlord to install, the forgoing provisions of this Section 9.1 shall apply; provided, however, in addition to paying the cost of the Tenant Alterations, Tenant also shall pay an administrative fee equal to fifteen percent (15%) of such cost to Landlord, as additional Rent under this Lease, and Landlord’s liability for such Tenant Alterations work shall be subject to and limited by the provisions of Article 17 below.

9.2 LIENS

Tenant shall not permit any lien or claim for lien of any mechanic, laborer or supplier or any other lien to be filed against the Building, the Land, the Premises, or any other part of the Property arising out of work performed, or alleged to have been performed by, or at the direction of, or on behalf of Tenant. If any such lien or claim for lien is filed, Tenant shall within ten (10)


00066513.5	38

days after receiving notice of such lien or claim (a) have such lien or claim for lien released of record or (b) deliver to Landlord a bond in form, content, amount, and issued by surety, satisfactory to Landlord, indemnifying, protecting, defending and holding harmless the Indemnitees against all costs and liabilities resulting from such lien or claim for lien and the foreclosure or attempted foreclosure thereof. If Tenant fails to take any of the above actions, Landlord, in addition to its rights and remedies under Article 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 attorneys’ fees.

(a) Emergency Generator. Landlord hereby agrees that, subject to the terms and provisions of this Section 9.3, Tenant’s compliance with all applicable Laws and all recorded covenants, conditions and restrictions affecting the Project, and subject to the approval of all applicable governmental authorities, Tenant shall have the right at Tenant’s sole cost and expense, to operate one (1) back-up emergency diesel generator (the “Emergency Generator”) within up to and including three (3) parking spaces within the parking lot serving the Building, in a location acceptable to Landlord (the “Emergency Generator Site”).

(b) Installation. The installation of the Emergency Generator (and any related Emergency Generator Connecting Equipment therefor) and the alteration, modification, and/or replacement of either of the Emergency Generator and/or any other Emergency Generator Connecting Equipment shall constitute an Alteration and shall be performed in accordance with and subject to the provisions of Section 9.1 of this Lease, including, without limitation, Tenant’s obligation to obtain Landlord’s prior consent to the size and other specifications of the Emergency Generator (and any related Emergency Generator Connecting Equipment therefor), the methods and locations of all connections to the Emergency Generator Equipment through the Building’s existing conduits, cables, risers and feeders, and any such alterations, modifications and/or replacements of or to the Emergency Generator Equipment. The Emergency Generator Equipment shall be treated for all purposes of this Lease as if the Emergency Generator Equipment were Tenant’s personal property. In no event shall Tenant be permitted to void any warranties pertaining to the Building or Project in connection with the installation, maintenance, use, operation, alteration, modification, and/or replacement of the Emergency Generator Equipment. Tenant, at Tenant’s sole cost and expense, shall maintain the Emergency Generator Equipment and install such noise reduction and other protective equipment on or about the Emergency Generator Equipment as Landlord may reasonably determine.

Except as otherwise specified in Section 9.3(e) below, Landlord shall not have any obligations with respect to the Emergency Generator Site, the Emergency Generator Equipment or compliance with any requirements relating thereto, nor shall Landlord be responsible for any damage that may be caused to the Emergency Generator Equipment. Landlord makes no representation that the Emergency Generator Equipment will be able to supply sufficient power to the Premises, and Tenant agrees that Landlord shall not be liable to Tenant therefor.

(e) Repairs and Maintenance. Landlord shall repair and maintain the Emergency Generator, and Tenant shall pay one hundred percent (100%) of the cost of such repair and maintenance, including, without limitation, the cost of repairing any damage to the Emergency Generator caused by Tenant’s use thereof or as a result of Tenant connecting to the Emergency Generator.

00066513.5	41

noncompliance relates, and make such repairs and restoration as required under Section 9.3(k) below with respect thereto.

Article 10
ASSIGNMENT AND SUBLETTING

10.1 ASSIGNMENT AND SUBLETTING

(a) 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 forty-five (45) days prior to the commencement date of the term of the proposed sublease or assignment. If Tenant proposes to sublease less than all of the Rentable Area of the Premises, the space proposed to be sublet and the space retained by Tenant must each be a marketable unit as reasonably determined by Landlord and otherwise in compliance with all Laws. Landlord shall notify Tenant in writing of its approval or disapproval of the proposed sublease or assignment or its decision to exercise its rights under Section 10.2 within thirty (30) days after receipt of Tenant’s Notice (and all required information). In no event may Tenant sublease any portion of the Premises or assign the Lease to any other tenant of the Project. Tenant shall submit for Landlord’s approval (which approval shall not be unreasonably withheld) any advertising which Tenant or its agents intend to use with respect to the space proposed to be sublet.


00066513.5	42

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

(i) the 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, Campus 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 current occupant of the Project or Campus or 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 reasonably deemed typical by Landlord for office/lab use in the Project; or

(vi) Tenant is in Default under this Lease.

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

(d) For purposes of this Article 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 (other than an Excluded Change In Majority Control, as defined below) if Tenant is a corporation whose shares of stock are not traded publicly. If Tenant is a general partnership, any change in the general partners of Tenant shall be deemed to be an assignment for purposes of this Lease. As used herein, an “Excluded Change in Majority Control” shall mean any change in the majority control of Tenant resulting from or associated with (i) any initial public offering of the capital stock or other equity interest of Tenant on any nationally recognized securities exchange or (ii) any bona fide capitalization, recapitalization or financing for the benefit of Tenant (a “Financing Event”); provided, however, in the case of a Financing Event, Tenant shall give Landlord written notice at least fifteen (15) days prior to the effective date of the Financing Event, together with evidence that Tenant shall continue to have a net worth

equal to or greater than Tenant’s net worth as of the date immediately prior to the Financing Event, or if prior notice is prohibited by a confidentiality agreement or securities regulations or related regulations, then as soon after the Financing Event as is permissible.

(e) So long as Tenant is not entering into a transaction described herein for the purpose of avoiding or otherwise circumventing the remaining terms of this Article, Tenant may, subject to Section 10.5, assign its entire interest under this Lease or sublease all or a portion of the Premises, without the consent of Landlord, to any of the following (each, a “Permitted Transferee”) (i) an Affiliate, or (ii) a successor to Tenant by purchase or other acquisition of Tenant’s capital stock or substantially all of Tenant’s assets or by merger, consolidation or reorganization, provided that all of the following conditions are satisfied: (1) Tenant is not then in Default under this Lease; (2) Tenant shall give Landlord written notice at least fifteen (15) days prior to the effective date of the proposed transfer together with the information required hereunder and such entity shall expressly assume Tenant’s obligations hereunder, or if prior notice is prohibited by a confidentiality agreement or securities regulations or related regulations, then as soon after the transfer as is permissible; (3) with respect to an assignment to an Affiliate, Tenant continues to have a net worth equal to or greater than Tenant’s net worth as of the date immediately prior to such transfer; and (4) with respect to a purchase, merger, consolidation or reorganization which results in Tenant ceasing to exist as a separate legal entity, Tenant’s successor shall have a net worth equal to Tenant’s net worth at the date immediately prior to such transfer.

(f) Notwithstanding anything in this Section 10.1 to the contrary, Tenant shall be permitted to allow its contractors (i.e., parties with whom Tenant contracts to provide special services, such as scientists) to occupy certain portions of the Premises without Landlord’s consent (for purposes of this Section 10.1(g), each such, person or company is referred to as an “Occupant”), provided the following conditions are satisfied: (i) such occupancy is not a subterfuge to avoid the provisions of this Article 10 concerning assignment and subleases; (ii) such occupancy is not separated from the remaining portions of the Premises by demising walls and does not have a separate entrance; (iii) each Occupant shall comply with the insurance requirements under Sections 16.1 and 16.2 (including naming Landlord and the Indemnitees required under Section 16.2 as additional insureds) as if such Occupant were Tenant (with Landlord having received evidence of such insurance prior to such Occupant’s occupancy of the Premises) and shall be subject to the waivers under Section 16.4 as if such Occupant were Tenant; (iv) prior to such Occupant’s occupancy of the Premises, Tenant shall have provided Landlord with the name and address of the Occupant and length of occupancy term for such Occupant; and (v) the aggregate space occupied by Occupants at any time does not exceed 1,000 rentable square feet. If an occupancy described above does not satisfy all of the foregoing conditions, then such occupancy shall constitute a sublease and shall be subject to the other provisions of this Section 10.1.

10.2 RECAPTURE

Excluding any assignment or sublease contemplated in Section 10.1(e), Landlord shall have the option to exclude from the Premises covered by this Lease (“recapture”) the space proposed to be sublet for substantially the remainder of the Term or subject to the assignment, effective as of the proposed commencement date of such sublease or assignment. If Landlord elects to recapture, Tenant shall surrender possession of the space proposed to be subleased or


00066513.5	44

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.

10.3 EXCESS RENT

Tenant shall pay Landlord on the first day of each month during the term of the sublease or assignment, as additional Rent under this Lease, fifty percent (50%) of the amount by which the sum of all rent and other consideration (direct or indirect) due from the subtenant or assignee for such month exceeds: (i) that portion of the Monthly Base Rent and Rent Adjustments due under this Lease for said month which is allocable to the space sublet or assigned; and (ii) the following costs and expenses for the subletting or assignment of such space: (1) brokerage commissions and attorneys’ fees and expenses, (2) the actual costs paid in making any improvements or substitutions in the Premises required by any sublease or assignment; (3) “free rent” periods, costs of any inducements or concessions given to subtenant or assignee; and (4) reasonable moving costs and other amounts actually paid with respect to such subtenant’s or assignee’s other leases or occupancy arrangements. All such costs and expenses shall be amortized over the term of the sublease or assignment pursuant to sound accounting principles.

10.4 TENANT LIABILITY

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

10.5 ASSUMPTION AND ATTORNMENT

If Tenant shall assign this Lease as permitted herein, the assignee shall expressly assume all of the obligations of Tenant hereunder accruing after the effective date of the assignment in a written instrument satisfactory to Landlord and furnished to Landlord not later than thirty (30) days prior to the effective date of the assignment. Each sublease by Tenant hereunder shall be subject and subordinate to this Lease and to the matters to which this Lease is or shall be subordinate, and each subtenant by entering into a sublease is deemed to have agreed that in the event of termination, re-entry or dispossession by Landlord under this Lease, Landlord may, at its


00066513.5	45

option, either terminate the sublease or take over all of the right, title and interest of Tenant, as sublandlord, under such sublease, and such subtenant shall, at Landlord’s option, attorn to Landlord pursuant to the then executory provisions of such sublease, except that Landlord shall not be: (1) liable for any previous act or omission of Tenant under such sublease; (2) subject to any counterclaim, offset or defense that such subtenant might have against Tenant; (3) bound by any previous modification of such sublease or by any rent or additional rent or advance rent which such subtenant might have paid for more than the current month to Tenant, and all such rent shall remain due and owing, notwithstanding such advance payment; (4) bound by any security or advance rental deposit made by such subtenant which is not delivered or paid over to Landlord and with respect to which such subtenant shall look solely to Tenant for refund or reimbursement; or (5) obligated to perform any work in the subleased space or to prepare it for occupancy, and in connection with such attornment, the subtenant shall execute and deliver to Landlord any instruments Landlord may reasonably request to evidence and confirm such attornment. Each subtenant or licensee of Tenant shall be deemed, automatically upon and as a condition of its occupying or using the Premises or any part thereof, to have agreed to be bound by the terms and conditions set forth in this Section 10.5. The provisions of this Section 10.5 shall be self-operative, and no further instrument shall be required to give effect to this provision.

10.6 PROCESSING EXPENSES

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), the sum of One Thousand Five Hundred Dollars ($1,500.00), plus all reasonable attorneys’ fees and expenses incurred by Landlord with respect to such proposed assignment or sublease, which attorneys’ fees and expenses shall not exceed $3,000.00 (collectively, “Processing Costs”); provided, however, that Tenant shall pay to Landlord any additional reasonable attorneys’ fees and expenses incurred by Landlord to the extent Tenant or its proposed assignee or subtenant does not execute Landlord’s standard form of consent. 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.

Article 11
DEFAULT AND REMEDIES

11.1 DEFAULT

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

(a) Tenant fails to pay any installment or other payment of Rent including Rent Adjustment Deposits or Rent Adjustments within five (5) days after the date when due;

(b) Tenant abandons the Premises;


00066513.5	46

(c) Tenant violates the restrictions on assignments and subleases set forth in Article 10 – Assignment and Subletting and fails to cure such default within five (5) Business Days after receipt of written notice thereof from Landlord;

(d) Tenant fails to maintain any insurance policy required of it hereunder, and fails to cure such default within five (5) Business Days after receipt of written notice thereof from Landlord;

(e) 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, or such longer time as may reasonably be required to cure the default, so long as Tenant commences such cure within thirty (30) days after written notice thereof and diligently pursues such cure to completion unless the failure to perform is a Default for which this Lease expressly specifies there is no cure or grace period;

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

(g) 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 Code, or any amendment, replacement or substitution therefor, or to delay payment of, reduce or modify Tenant’s debts, which in the case of an involuntary action is not discharged within thirty (30) days;

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

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

(j) 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;

(k) upon the dissolution of Tenant; or

(l) upon the third occurrence during any twelve (12)-month period during the Term that Tenant fails to pay Rent when due or has breached a particular covenant of this Lease (whether or not such failure or breach is thereafter cured within any stated cure or grace period or statutory period).

11.2 LANDLORD’S REMEDIES

(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.


00066513.5	47

(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; and

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


00066513.5	48

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, 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 (lessor may continue Lease in effect after lessee’s breach and abandonment and recover Rent as it becomes due, if lessee 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, such consent shall be governed by the terms and conditions of Article 10 above. Tenant acknowledges and agrees that the provisions of Article 10 shall be deemed to constitute reasonable limitations of Tenant’s right to assign or sublet. Tenant acknowledges and agrees that in the absence of written notice pursuant to Section 11.2(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 relet the Premises or the appointment of a receiver upon initiative of Landlord to protect Landlord’s interest under this Lease or the withholding of consent to a subletting or assignment, or terminating a subletting or assignment, if in accordance with other provisions of this Lease.

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

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

(f) Notwithstanding any other provision of this Lease, a notice to Tenant given under this Article and Article 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.


00066513.5	49

(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 25.16 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.

11.3 ATTORNEY’S FEES

In the event any party brings any suit or other proceeding with respect to the subject matter or enforcement of this Lease, the prevailing party (as determined by the court, agency or other authority before which such suit or proceeding is commenced) shall, in addition to such other relief as may be awarded, be entitled to recover attorneys’ fees, expenses and costs of investigation as actually incurred, including court costs, expert witness fees, costs and expenses of investigation, and all attorneys’ fees, costs and expenses in any such suit or proceeding (including in any action or participation in or in connection with any case or proceeding under the Bankruptcy Xxxx, 00 Xxxxxx Xxxxxx Code Sections 101 et seq. (the “Bankruptcy Code”), or any successor statutes, in establishing or enforcing the right to indemnification, in appellate proceedings, or in connection with the enforcement or collection of any judgment obtained in any such suit or proceeding).

11.4 BANKRUPTCY

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 (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.


00066513.5	50

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

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

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

(ii) Landlord has obtained consents or waivers from any third parties 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.

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

11.5 LANDLORD’S DEFAULT

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 any Mortgagee notice and a reasonable time to cure any default by Landlord (as specified in Section 23.2 below).

Article 12
SURRENDER OF PREMISES

12.1 IN GENERAL

Upon the Termination Date, Tenant shall surrender and vacate the Premises immediately and deliver possession thereof to Landlord in a clean, good and tenantable condition, ordinary wear and tear, Hazardous Materials (other than those which are Tenant’s responsibility hereunder), casualty and condemnation, and damage caused by Landlord excepted. Tenant shall deliver to Landlord all keys to the Premises. All improvements in and to the Premises, including any Tenant


00066513.5	51

Alterations (collectively, “Leasehold Improvements”) shall remain upon the Premises at the end of the Term without compensation to Tenant. Tenant’s trade fixtures, furniture, equipment and other personal property installed in the Premises (“Tenant’s Property”) shall at all times be and remain Tenant’s property. Except for Alterations which cannot be removed without structural injury to the Premises, at any time Tenant may remove Tenant’s Property from the Premises, provided that Tenant repairs all damage caused by such removal. Landlord shall have no lien or other interest in any item of Tenant’s Property. Landlord, however, by written notice to Tenant at least thirty (30) days prior to the Termination Date, may require Tenant, at its expense, to remove (a) any Cable, and (b) any Tenant Additions (collectively referred to as “Required Removables”). Required Removables may include, without limitation, internal stairways, 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 Section 12.1 must comply with the Project’s Sustainability Practices and Tenant is strongly encouraged to comply with 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. 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. Notwithstanding anything in this Section 12.1 to the contrary, failure by Tenant to strictly comply with the provisions of this Section 12.1 with respect to any Required Removables that are required to be removed from the Premises by Tenant hereunder shall constitute a failure of Tenant to validly surrender the Premises.

12.2 LANDLORD’S RIGHTS

All property which may be removed from the Premises by Landlord shall be conclusively presumed to have been abandoned by Tenant and Landlord may deal with such property as provided in Section 11.2(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 Tenant Additions and in restoring the Premises to the condition required by this Lease.

Article 13
HOLDING OVER

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 (i) 150% of the monthly Rent payable for the month immediately preceding the holding over (including increases for Rent Adjustments which Landlord may reasonably estimate) for the first 90 days of such holdover and (ii) 200% of the monthly Rent payable for the month immediately preceding the holding over (including increases for Rent Adjustments which Landlord may reasonably estimate) after the first 90 days of such holdover. Tenant shall also pay all damages, excluding, however, consequential damages (i.e., loss of income from prospective tenants), sustained by Landlord by reason of such holding over. The provisions of this Article


00066513.5	52

shall not constitute a waiver by Landlord of any re-entry rights of Landlord, and Tenant’s continued occupancy of the Premises shall be as a tenancy in sufferance.

Article 14
DAMAGE BY FIRE OR OTHER CASUALTY

14.1 SUBSTANTIAL UNTENANTABILITY

(a) If any fire or other casualty (whether insured or uninsured) renders all or a substantial portion of the Premises or the Building untenantable, Landlord shall, with reasonable promptness after the occurrence of such damage, estimate the length of time that will be required to substantially complete the repair and restoration and shall, by notice advise Tenant of such estimate (“Landlord’s Notice”). If Landlord estimates that the amount of time required to substantially complete such repair and restoration will exceed two hundred seventy (270) 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 twenty (20) days after delivery of Landlord’s Notice, provided that if Landlord so chooses, Landlord’s Notice may also constitute such notice of termination.

(b) 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.

(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 those proceeds of Tenant’s insurance for its own personal property and equipment which would be removable by Tenant at the Termination Date. All such insurance proceeds shall be payable to Landlord whether or not the Premises are to be repaired and restored; provided, however, if this Lease is not terminated and the parties proceed to repair and restore Tenant Additions at Tenant’s cost, to the extent Landlord received proceeds of Tenant’s insurance covering Tenant Additions, such proceeds shall be applied to reimburse Tenant for its cost of repairing and restoring Tenant Additions.

(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 willful misconduct or gross negligence 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


00066513.5	53

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.

14.2 INSUBSTANTIAL UNTENANTABILITY

If the Premises or the Building is damaged by a casualty but neither is rendered substantially untenantable and either (i) Landlord estimates that the time to substantially complete the repair or restoration will not exceed two hundred seventy (270) days from the date such damage occurred, or (ii) the cost to repair or restore is less than ten percent (10%) of the replacement cost of the Building, then Landlord shall proceed to repair and restore the Building or the Premises other than Tenant Additions, with reasonable promptness, unless such damage is to the Premises and occurs during the last six (6) months of the Term, in which event either Tenant or Landlord shall have the right to terminate this Lease as of the date of such casualty by giving written notice thereof to the other within twenty (20) days after the date of such casualty. Notwithstanding the aforesaid, Landlord’s obligation to repair shall be limited in accordance with the provisions of Section 14.1 above.

14.3 RENT ABATEMENT

Except if due to the willful misconduct of Tenant or its employees, 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 xxxxx for that part of the Premises which is untenantable on a per diem basis from the date of the casualty until Landlord has Substantially Completed the repair and restoration work in the Premises which it is required to perform, provided, that as a result of such casualty, Tenant does not occupy the portion of the Premises which is untenantable during such period.

14.4 WAIVER OF STATUTORY REMEDIES

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.

Article 15
EMINENT DOMAIN

15.1 TAKING OF WHOLE OR SUBSTANTIAL PART

In the event the whole or any substantial part of the Building or of the Premises is taken or condemned by any competent authority for any public use or purpose (including a deed given in lieu of condemnation) and is thereby rendered untenantable, this Lease shall terminate as of the


00066513.5	54

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.

15.2 TAKING OF PART

Article 23
MORTGAGEE PROTECTION

23.1 SUBORDINATION AND ATTORNMENT

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 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 (1) month in advance except payments in the nature of security for the performance by Tenant of its obligations under this Lease; (ii) subject to any offset, defense or damages arising out of a default of any obligations of any preceding Landlord; or (iii) bound by any amendment or modification of this Lease made without the written consent of the Mortgagee or ground lessor; or (iv) liable for any security deposits not actually received in cash by such purchaser or ground lessor. Notwithstanding the foregoing, Landlord agrees that upon written request from Tenant, Landlord shall request that any future Mortgagee provide a nondisturbance agreement to Tenant on such Mortgagee’s standard form. In confirmation of such subordination, however, Tenant shall execute promptly any 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 after 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.


00066513.5	61

23.2 MORTGAGEE PROTECTION

Tenant agrees to give any Mortgagee or ground lessor, by registered or certified mail, a copy of any notice of default served upon Landlord by Tenant, provided that prior to such notice Tenant has received notice (by way of service on Tenant of a copy of an assignment of rents and leases, or otherwise) of the address of such Mortgagee or ground lessor. Tenant further agrees that if Landlord shall have failed to cure such default within the time provided for in this Lease, then the Mortgagee or ground lessor shall have an additional thirty (30) days after receipt of notice thereof within which to cure such default or if such default cannot be cured within that time, then such additional notice time as may be necessary, if, within such thirty (30) days, any Mortgagee or ground lessor has commenced and is diligently pursuing the remedies necessary to cure such default (including commencement of foreclosure proceedings or other proceedings to acquire possession of the Real Property, if necessary to effect such cure). Such period of time shall be extended by any period within which such Mortgagee or ground lessor is prevented from commencing or pursuing such foreclosure proceedings or other proceedings to acquire possession of the Real Property by reason of Landlord’s bankruptcy. Until the time allowed as aforesaid for Mortgagee or ground lessor to cure such defaults has expired without cure, Tenant shall have no right to, and shall not, terminate this Lease on account of default. This Lease may not be modified or amended so as to reduce the Rent or shorten the Term, or so as to adversely affect in any other respect to any material extent the rights of 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 shall make commercially reasonable efforts to obtain from Landlord’s current Mortgagee a form of non-disturbance agreement in favor of Tenant on Mortgagee’s standard form, provided that Tenant shall pay any costs associated with obtaining such agreement (which costs shall not exceed Three Thousand Dollars ($3,000.00)) and in no event shall obtaining such agreement be a condition to Tenant’s execution of or obligations under this Lease.

Article 24

(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 Article 24, 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


00066513.5	62

because of changed address of which no notice was given, as indicated by advice from Federal Express or other overnight courier service or by mail return receipt, shall be deemed to be receipt of notice, demand or request sent. Notices may also be served by personal service upon any officer, director or partner of Landlord or Tenant, and shall be effective upon such service.

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

Article 25
MISCELLANEOUS

25.1 LATE CHARGES

(a) All payments required hereunder (other than the Monthly Base Rent, Rent Adjustments, and Rent Adjustment Deposits, which shall be due as hereinbefore provided) to Landlord shall be paid within ten (10) business days after Landlord’s written invoice therefor together with reasonable back-up information substantiating the invoiced payments. 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, provided, however, that Landlord agrees to waive the first such late charge in each calendar year during the Term. 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, (ii) the amount of such late charge represents a reasonable estimate of such costs and expenses and that such late charge shall be paid to Landlord for each delinquent payment in addition to all Rent otherwise due hereunder. The parties further agree that the payment of late charges and the payment of interest provided for in subparagraph (a) above are distinct and separate from one another in that the payment of interest is to compensate Landlord for its inability to use the money improperly withheld by Tenant, while the payment of late charges is to compensate Landlord for its additional administrative expenses in handling and processing delinquent payments.

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

25.2 NO JURY TRIAL; VENUE; JURISDICTION

To the fullest extent permitted by Laws, each party hereto (which includes any assignee, successor, heir or personal representative of a party) shall not seek a jury trial, hereby waives trial


00066513.5	63

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.

25.3 NO DISCRIMINATION

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.

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.

25.5 OPTION

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.

25.6 AUTHORITY

Tenant represents and warrants to Landlord that it has full authority and power to enter into and perform its obligations under this Lease, that the person executing this Lease on Tenant’s

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.

25.10 ACCORD AND SATISFACTION

No payment by Tenant or receipt by Landlord of a lesser amount than any installment or payment of Rent due shall be deemed to be other than on account of the amount due, and no endorsement or statement on any check or any letter accompanying any check or payment of Rent shall be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such installment or payment of Rent or pursue any other remedies available to Landlord. No receipt of money by Landlord from Tenant after the termination of this Lease or Tenant’s right of possession of the Premises shall reinstate, continue or extend the Term. Receipt or acceptance of payment from anyone other than Tenant, including an assignee of Tenant, is not a waiver of any breach of Article 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 no event will Landlord be obligated to make disbursements pursuant to this Work Agreement in a total amount which exceeds the Tenant Improvement Allowance. Tenant must complete all Tenant Work and have submitted Payment Request Supporting Documentation (defined below) for such work, in each case subject to day for day extension due to Force Majeure, no later than June 30, 2023, in order to be entitled to receive the Tenant Improvement Allowance for such work.

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.

(b) Space Plan. Tenant shall supply Landlord for Landlord’s review and approval with a copy (which may be in electronic form) of its space plan for the Premises (“Space Plan”) before any architectural working drawings or engineering drawings have been commenced.
