The failure of Landlord to timely furnish the Estimate Statement for any Expense Year shall not preclude Landlord from enforcing its rights to collect any Estimated Project Expenses under this Section 3.2, nor shall Landlord be prohibited from revising any Estimate Statement theretofore delivered to the extent necessary, provided that the Estimate Statement shall not be revised more than two (2) times per Expense Year. Thereafter, Tenant shall pay, with its next installment of Base Monthly Rent due, a fraction of the Estimated Project Expenses for the then-current Expense Year (reduced by any amounts paid pursuant to the last sentence of this Section 3.2.4.1). Such fraction shall have as its numerator the number of months which have elapsed in such current Expense Year, including the month of such payment, and twelve (12) as its denominator. Until a new Estimate Statement is furnished (which Landlord shall have the right to deliver to Tenant at any time), Tenant shall pay monthly, with the Base Monthly Rent installments, an amount equal to one-twelfth (1/12) of the total Estimated Project Expenses set forth in the previous Estimate Statement delivered by Landlord to Tenant.

3.2.4.2Statement of Actual Project Expenses. In addition, Landlord shall give to Tenant no later than one hundred eighty (180) days following the end of each Expense Year, a statement (the "Statement") which shall state the Project Expenses incurred or accrued for such preceding Expense Year, and which shall indicate the amount of Tenant's Share of Project Expenses. Upon receipt of the Statement for each Expense Year commencing or ending during the Lease Term, Tenant shall pay, with its next installment of Base Monthly Rent due, or within thirty (30) days, whichever is earlier, the full amount of Tenant's Share of Project Expenses for such Expense Year, less the amounts, if any, paid during such Expense Year as Estimated Project Expenses, and if Tenant paid more as Estimated Project Expenses than the actual Tenant's Share of Project Expenses (an "Excess"), Tenant shall receive a credit in the amount of such Excess against Rent next due under this Lease. Even though the Lease Term has expired and Tenant has vacated the Premises, when the final determination is made of Tenant's Share of Project Expenses for the Expense Year in which this Lease terminates, if Tenant's Share of Project Expenses is greater than the amount of Estimated Project Expenses previously paid by Tenant to Landlord, Tenant shall, within thirty (30) days after receipt of the Statement, pay to Landlord such amount, and if Tenant paid more as Estimated Project Expenses than the actual Tenant's Share of Project Expenses (again, an Excess), Landlord shall, within thirty (30) days, deliver a check payable to Tenant in the amount of such Excess. The provisions of this Section 3.2.4.2 shall survive the expiration or earlier termination of the Lease Term, provided that, other than Tax Expenses and costs incurred for utilities, Tenant shall not be responsible for Tenant's Share of Project Expenses which are first billed to Tenant more than two (2) calendar years after the end of the Expense Year to which such Project Expenses relate; provided, however, with respect to any

amounts not included in the original Statement, Landlord shall bill Tenant for such Project Expense within sixty (60) days of Landlord’s receipt of the invoice therefor.

3.2.5.Taxes and Other Charges for Which Tenant is Directly Responsible.

3.2.5.1Tenant shall be liable for and shall pay thirty (30) days before delinquency, any and all taxes levied against Tenant's equipment, furniture, fixtures and any other personal property (including Prior Tenant's FF&E, if any) ("FF&E") located in or about the Premises. If any such taxes on Tenant's FF&E are levied against Landlord or Landlord's property, or if the assessed value of Landlord's property is increased by the inclusion therein of a value placed upon such FF&E, and if Landlord pays the taxes based upon such increased assessment, which Landlord shall have the right to do regardless of the validity thereof but only under proper protest if requested by Tenant, Tenant shall, within ten (10) business days following demand, repay to Landlord the taxes so levied against Landlord or the proportion of such taxes resulting from such increase in the assessment, as the case may be.

3.2.5.2If the tenant improvements in the Premises, whether installed and/or paid for by Landlord or Tenant and whether or not affixed to the real property so as to become a part thereof, are assessed for real property tax purposes at a valuation higher than the valuation at which tenant improvements conforming to Landlord's "building standard" in other space in the Building are assessed, then the Real Property Taxes levied against Landlord or the property by reason of such excess assessed valuation shall be deemed to be taxes levied against personal property of Tenant and shall be governed by the provisions of Section 3.2.5.1, above.

3.2.5.3Notwithstanding any contrary provision herein, Tenant shall pay prior to delinquency any (i) rent tax or sales tax, gross receipts tax, service tax, transfer tax or value added tax, business tax or any other applicable tax on the rent or services herein or otherwise respecting this Lease, (ii) taxes assessed upon or with respect to the possession, leasing, operation, management, maintenance, alteration, repair, use or occupancy by Tenant of the Premises or any portion of the Project, including the parking facility for the Project; or (iii) taxes assessed upon this transaction or any document to which Tenant is a party creating or transferring an interest or an estate in the Premises.

3.3Payment of Rent. Concurrently with the execution of this Lease by Tenant, Tenant shall pay to Landlord the amount set forth in Section N of the Summary as prepayment of the first installment of Base Monthly Rent due after any abatement period. All Rent required to be paid under this Lease in monthly installments shall be paid to Landlord in advance on the first day of each calendar month during the Lease Term. All Rent shall be paid in lawful money of the United States, without any abatement, deduction or offset whatsoever (except as specifically provided herein), and without any prior notice or demand therefor. Rent shall be paid to Landlord pursuant to the electronic wiring instructions set forth in Section Q of the Summary, or, at Landlord's option, pursuant to such other electronic wiring instructions or to such other party or at such other place as Landlord may designate from time to time in writing, by notice to Tenant in accordance with the provisions of Section 21.5 of this Lease. If any Rent payment date (including the Lease Commencement Date) falls on a day of the month other than the first day of such month, or if any payment of Rent is for a period which is shorter than one month, the Rent for any fractional month shall accrue on a daily basis for the period from the date such payment is due to the end of such calendar month or to the end of the Lease Term at a rate per day which is equal to 1/365 of the applicable annual Rent. All other payments or adjustments required to be made under the terms of this Lease that require proration on a time basis shall be prorated on the same basis. Landlord shall have the right, upon at least ten (10) days' prior written notice to Tenant (i) to change the name of the depository for receipt of any payment of Rent made by means of a federal funds wire transfer or such other method of electronic funds transfer ("Electronic Payment"), and (ii) to discontinue payment of any sum due from Tenant to Landlord under this Lease by Electronic Payment.

3.4Late Charge, Interest and Quarterly Payments.

3.4.1.Late Charge. Tenant acknowledges that its failure to pay when due any installment of Rent, or any other sum of money required to be paid by Tenant under this Lease, will cause Landlord to incur certain costs and expenses not contemplated under this Lease, the exact amount of such costs being extremely difficult and impractical to determine. If any installment of Rent is not received by Landlord from Tenant upon the date such payment is due, then Tenant shall pay to Landlord a late charge equal to ten percent (10%) of the overdue amount plus any attorney's fees incurred by Landlord by reason of Tenant's failure to pay Rent and/or other charges when due hereunder, provided, however, that Landlord shall waive the imposition of the late charge for the first late payment in any calendar year during the Lease Term provided Tenant pays such overdue amounts within three (3) business days following written notice from Landlord that such amounts are past due. In no event shall the terms of this Section 3.4.1 be deemed to grant to Tenant a grace period or extension of time within which to pay any installment of Rent when due

hereunder, or prevent Landlord from exercising any right or remedy available to Landlord upon Tenant's failure to pay any installment of Rent due under this Lease in a timely fashion.

3.4.2.Interest. In addition to the late charge set forth above, if any installment of Rent remains delinquent for a period in excess of ten (10) days after the date when due, then such amount shall bear interest at a rate equal to the lesser of (i) ten percent (10%), or (ii) the maximum rate permitted by law in the state in which the Project is located (the "Agreed Interest Rate") from the date when such installment of Rent was due until paid.

3.5Intentionally Omitted.

3.6Landlord's Books and Records. Following Tenant’s receipt of the Statement, Tenant shall have the right, upon prior written notice to Landlord ("Audit Notice"), to commence and complete an audit of Landlord’s books and records concerning the Project Expenses for the Landlord's fiscal year that is the subject of such Statement (the "Records"), within ninety (90) days following the delivery of such Statement (the “Review Period”). Following delivery of an Audit Notice, and provided Tenant is not then in default after the expiration of any applicable notice and cure period under this Lease, Tenant shall have the right, at Tenant's sole cost, during Landlord's regular business hours and on ten (10) days prior notice to Landlord, to audit the Records at Landlord's principal business office (or at any other location in northern California designated by Landlord) ("Tenant's Audit"). Such audit shall occur within sixty (60) days following the delivery of the Audit Notice. Tenant's audit of the Records pursuant to this Section 3.6 shall be conducted only by a reputable independent nationally or regionally recognized certified public accounting firm, which accounting firm: (i) shall have previous experience in auditing financial operating records of landlords of office buildings; (ii) shall not be retained by Tenant on a contingency fee basis (i.e. Tenant must be billed based on the actual time and materials that are incurred by the accounting firm in the performance of the audit), and a copy of the executed audit agreement between Tenant and auditor shall be provided to Landlord prior to the commencement of the audit; and (iii) at Landlord’s option, both Tenant and auditor shall be required to execute a commercially reasonable confidentially agreement prepared by Landlord. Any audit report prepared by Tenant’s auditors shall be delivered concurrently to Landlord and Tenant within the Review Period. If the parties are unable to resolve the dispute within sixty (60) days after completion of Tenant’s Audit, then, at Tenant's request, a certified public accounting firm mutually selected by Landlord and Tenant, shall, at Tenant's cost, conduct an audit of the relevant Project Expenses (the "Neutral Audit"). Tenant shall pay all costs and expenses of the Neutral Audit and Tenant’s review of the Records unless the final determination in such Neutral Audit is that Landlord overstated Project Expenses in the annual reconciliation Statement for the year being audited by more than five percent (5%), in which case Landlord shall pay the actual and reasonable costs and expenses of the Neutral Audit and Tenant’s Audit, not to exceed an aggregate amount equal to $10,000.00. In any event, Landlord will promptly reimburse Tenant or provide a credit for any overstatement of Project Expenses, and Tenant shall promptly pay to Landlord any understatement of Project Expenses. The foregoing audit and Neutral Audit procedures shall be the sole methods to be used by Tenant to dispute the amount of any Project Expenses payable by Tenant pursuant to the terms of this Lease.

4.1Permitted Uses. Tenant shall use the Premises solely for the Permitted Use specified in Section P of the Summary, and Tenant shall not use or permit the Premises, the Building or the Project to be used for any other purpose or purposes whatsoever without the prior written consent of Landlord, which consent may be withheld in Landlord's sole and absolute discretion.

4.2Prohibited Uses. Tenant further covenants and agrees that Tenant shall not use, or suffer or permit any person(s) to use, the Premises in any manner which (i) will cause structural injury or material damage to the Building; or (ii) is contrary to the provisions of any rules and regulations as promulgated by Landlord from time to time, or is in violation of the laws of the United States of America, the State of California, or the ordinances, regulations or requirements of the local municipal or county governing body having jurisdiction over the Project (collectively, "Laws"), including, without limitation, any such laws, ordinances, regulations or requirements relating to Hazardous Materials, as that term is defined in Section 7.1.6, below. Tenant shall not operate any equipment within the Premises which will (A) materially damage the Building or the Common Areas; (B) overload existing electrical systems or other mechanical equipment servicing the Building and/or the Premises; (C) impair the efficient operation of the sprinkler system or the heating, ventilating or air conditioning ("HVAC") system and equipment servicing the Building and/or the Premises; or (D) damage, overload or corrode the sanitary sewer system for the Project and/or the Building.

4.3Compliance with Law.

4.3.1.In General. Tenant shall not do anything or suffer anything to be done in or about the Premises or the Project which will in any way conflict with (i) any Laws now in force or which may hereafter be enacted or promulgated, or (ii) any recorded covenants, conditions and restrictions, private agreements, reciprocal easement agreements, or other recorded instruments affecting the use of the Premises, the Building or the Project (individually and collectively, "Private Restrictions"). At its sole cost and expense, Tenant shall promptly observe and comply with all Laws and Private Restrictions. Should any standard or regulation now or hereafter be imposed on Landlord or Tenant by a state, federal or local governmental body charged with the establishment, regulation and enforcement of occupational, health or safety standards for employers, employees, landlords or tenants, then Tenant agrees, at its sole cost and expense, to promptly comply with such standards or regulations and to cooperate with Landlord, including, without limitation, by taking such actions as Landlord may reasonably require, in Landlord's efforts to comply with such standards or regulations. Tenant shall, at Tenant's expense, make any alterations, improvements, additions or changes to the Premises or the Building as are required to comply with any and all Laws, and resulting from or related to (i) the Premises, (ii) Tenant's use of the Premises (but with respect to alterations, improvements, additions or changes to the Building Structure, only if triggered by Tenant's use of the Premises for non-general office use), (iii) Tenant's application for any permit or government approval; or (iv) Tenant's construction or installation of any Alterations (as defined in Section 5.1, below) in the Premises. Any other alterations, improvements, additions, or changes required to comply with any Laws which are not the responsibility of Tenant pursuant to the immediately preceding sentence shall be made by Landlord, and the cost thereof shall be prorated and paid as Operating Expenses. The judgment of any court of competent jurisdiction or the admission of Tenant in any judicial action, regardless of whether Landlord is a party thereto, that Tenant has violated any of said governmental measures, shall be conclusive of that fact as between Landlord and Tenant. Tenant shall promptly pay all fines, penalties and damages that may arise out of or be imposed because of its failure to comply with the provisions of this Section 4.3. Tenant shall not use the Premises, the Building or the Project in any manner which will cause a cancellation of any insurance policy carried by either Landlord or Tenant pursuant to this Lease. Tenant shall not keep, use or sell, or permit to be kept, used, or sold in or about the Premises any article which may be prohibited by a standard form of fire insurance policy. Tenant shall comply with all reasonable requirements of any insurance company, insurance underwriter, or Board of Fire Underwriters which are necessary to maintain the insurance coverage carried by either Landlord or Tenant pursuant to this Lease.

4.3.2.Disability Access Disclosure Under Section 1938 of the California Civil Code. Landlord makes the following statement in accordance with Section 1938 of the California Civil Code. Neither the Leased Premises nor the Complex has undergone an inspection by a Certified Access Specialist to determine if the Leased Premises or Complex meet all applicable construction related accessibility standards pursuant to Section 55.53 of the California Civil Code. As required by Section 1938(e) of the California Civil Code, Landlord hereby states as follows:  "A Certified Access Specialist (CASp) can inspect the subject premises and determine whether the subject premises comply with all of the applicable construction-related accessibility standards under state law.  Although state law does not require a CASp inspection of the subject premises, the commercial property owner or lessor may not prohibit the lessee or tenant from obtaining a CASp inspection of the subject premises for the occupancy or potential occupancy of the lessee or tenant, if requested by the lessee or tenant.  The parties shall mutually agree on the arrangements for the time and manner of the CASp inspection, the payment of the fee for the CASp inspection, and the cost of making any repairs necessary to correct violations of construction-related accessibility standards within the premises."  In furtherance of the foregoing, notwithstanding any provision to the contrary in this Lease, Landlord and Tenant hereby agree as follows:  (a) any CASp inspection requested by Tenant shall be conducted, at Tenant's sole cost and expense, by a CASp approved in advance by Landlord, which approval shall not be unreasonably withheld, conditioned or delayed; and (b) Tenant, at its cost, is responsible for making any repairs within the Leased Premises to correct violations of construction-related accessibility standards; and, if any CASp inspection requested by Tenant shall require repairs to the Building (outside the Leased Premises) to correct violations of construction-related accessibility standards, then Tenant shall, at Landlord's option, either perform such repairs at Tenant's sole cost and expense or reimburse Landlord within ten (10) business days following demand, as additional Rent, for the cost to Landlord of performing such repairs.

4.4Rules and Regulations. Landlord may from time to time promulgate reasonable and nondiscriminatory rules and regulations ("Rules and Regulations") applicable to all occupants of the Project for the care and orderly management of the Project, and the safety of its tenants and invitees. Such Rules and Regulations shall be binding upon Tenant upon delivery of a copy thereof to Tenant, and Tenant hereby agrees to abide by such Rules and Regulations. If there is a conflict between the Rules and Regulations and any of the provisions of this Lease, the provisions of this Lease shall prevail. Landlord shall not be responsible for the violation by any other tenant of the Project of any such Rules and Regulations.

5.1Landlord's Consent to Alterations. Tenant shall not make or suffer to be made any improvements, alterations, additions, changes or repairs (pursuant to Article 6 or otherwise) to the Premises (collectively, "Alterations") without Landlord's prior written approval of same, which approval shall be requested by Tenant not less than twenty (20) business days prior to the commencement thereof, and which approval shall not be unreasonably withheld, conditioned or delayed by Landlord; provided that it shall be deemed reasonable for Landlord to withhold its consent to any Alterations which affect any area(s) outside of the Premises, the exterior of the Building, the Building Systems or any structural portion of the Building. In addition, Tenant shall not make or suffer to be made any Alteration which would invalidate any warranty held by Landlord at the Project (including, without limitation, with respect to the roof of the Building). Notwithstanding the foregoing, Landlord's prior consent shall not be required for any Alteration that: (a) is solely cosmetic in nature (such as painting or decorating); (b) does not affect any area outside of the Premises, or require work inside the walls, or above the ceiling of the Premises; (c) does not affect (1) the roof or any structural portion of the Building (the "Building Structure"), or (2) the plumbing, sewer, drainage, electrical, fire protection, elevator, life safety and security systems and equipment, HVAC systems, and all other mechanical, electrical and communications systems and equipment, which are located in the Building or outside the Building and which exclusively serve the Building (collectively, the "Building Systems"); (d) cannot be seen from outside the Premises, and (e) costs less than $100,000 in the aggregate during any twelve (12) month period of the Lease Term (herein referred to as "Cosmetic Alterations"); provided that Tenant shall provide Landlord with prior written notice of any Cosmetic Alteration at least fifteen (15) business days' prior to Tenant's commencement of same. The construction of any initial improvements in the Premises shall be governed by the terms of the Tenant Work Letter, if any, attached hereto as Exhibit B, and not the terms of this Article 5.

5.2Manner of Construction. Landlord may impose, as a condition of its consent to any and all Alterations or repairs of the Premises or about the Premises, such requirements as Landlord in its reasonable discretion may deem desirable, including, but not limited to, the requirement that Tenant utilize for such purposes only contractors reasonably approved by Landlord. Tenant shall construct such Alterations and perform such repairs in a good and workmanlike manner, in conformance with any and all Laws and pursuant to a valid building permit, all in conformance with Landlord's construction rules and regulations. In the event Tenant performs any Alterations in the Premises which require or give rise to governmentally required changes to the Base Building, as that term is defined below, then Landlord shall, at Tenant's expense, make such changes to the Base Building. The "Base Building" shall mean the Building Structure and the Building Systems. In performing the work of any such Alterations, Tenant shall have the work performed in such manner so as not to obstruct access to the Project or any portion thereof, by any other tenant of the Project, and so as not to obstruct the business of Landlord or other tenants in the Project. Tenant shall not use (and upon notice from Landlord shall cease using) contractors, services, workmen, labor, materials or equipment that, in Landlord's reasonable judgment, would disturb labor harmony with the workforce or trades engaged in performing other work, labor or services in or about the Building or the Common Areas. Upon completion of any Alterations, Tenant agrees to cause a Notice of Completion to be recorded in the office of the recorder of the County in which the Premises are situated in accordance with California Civil Code Section 8180 et. seq., or any successor statute, and Tenant shall deliver to the Project construction manager a reproducible copy of the "as built" drawings of the Alterations, to the extent applicable, as well as all permits, approvals and other documents issued by any governmental agency in connection with the Alterations. If Tenant fails to complete any required removal of any Alterations, improvements, equipment and/or appurtenances in the Premises and/or to repair any damage caused by such removal pursuant to the terms of this Section 5.2, then Rent shall continue to accrue under this Lease in accordance with Article 16, below, after the end of the Lease Term until such work shall be completed, and Landlord shall have the right, but not the obligation, to perform such work and to charge the cost thereof to Tenant. Tenant hereby protects, defends, indemnifies and holds Landlord harmless from any liability, cost, obligation, expense or claim of lien, including but not limited to, court costs and reasonable attorneys' fees, in any manner relating to the installation, placement, removal or financing of any such Alterations, improvements, fixtures, equipment and/or appurtenances in, on or about the Premises, which obligations of Tenant shall survive the expiration or earlier termination of this Lease.

5.3Payment for Alterations. If payment is made directly to contractors, Tenant shall (i) comply with Landlord's requirements for final lien releases and waivers in connection with Tenant's payment for work to contractors, and (ii) sign Landlord's standard contractor's rules and regulations. Whether or not Tenant orders any work directly from Landlord, Tenant shall reimburse Landlord for Landlord's reasonable, actual, out-of-pocket costs and expenses actually incurred in connection with Landlord's review of such work.

5.4Construction Insurance. In the event that any Alterations are made pursuant to this Article 5, prior to the commencement of such Alterations, Tenant shall provide Landlord with evidence that Tenant or Tenant's contractor carries "Builder's All Risk" insurance in an amount reasonably approved by Landlord covering the construction of such

Alterations, and such other insurance as Landlord may reasonably require, it being understood and agreed that all of such Alterations shall be insured by Tenant pursuant to Section 9.1.3 of this Lease immediately upon completion thereof. In addition, Landlord may, in its reasonable discretion, require Tenant to obtain a lien and completion bond or some alternate form of security satisfactory to Landlord in an amount sufficient to ensure the lien-free completion of such Alterations and naming Landlord as a co-obligee.

5.5Restoration. All Alterations, improvements, fixtures, equipment and/or appurtenances which may be installed or placed in or about the Premises from time to time shall be at the sole cost of Tenant, and any permanently affixed Alterations, improvements, fixtures, equipment and/or appurtenances shall become the property of Landlord upon the expiration or earlier termination of this Lease; provided, however, Landlord may, by written notice to Tenant prior to the expiration or earlier termination of the Lease Term, require Tenant, at Tenant's expense, to remove any permanently-fixed Alterations or improvements and to repair any damage to the Premises and Building caused by such removal and return any affected portion of the Premises to the condition existing prior to the installation of such Alterations or improvements; provided further, however, notwithstanding the foregoing, Landlord shall notify Tenant whether the applicable Alteration or improvement will be required to be removed pursuant to the terms of this Section 5.5 at the time of Tenant's request for Landlord's consent to any Alteration or improvement. If Tenant fails to complete the removal of any Alterations or improvements as set forth in this Section 5.5, then Landlord shall have the right, but not the obligation, to perform such work and to charge the cost thereof to Tenant.

5.6Removal of Communications and Computer Lines. Tenant may install, maintain, replace, remove or use any communications or computer wires and cables (collectively, the "Lines") at the Project in or exclusively serving the Premises, provided that (i) Tenant shall obtain Landlord's prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed), use an experienced and qualified contractor approved in writing by Landlord, and comply with all of the other provisions of Articles 5 and 6 of this Lease, (ii) if applicable, an acceptable number of spare Lines and space for additional Lines shall be maintained for existing and future occupants of the Building, as determined in Landlord's reasonable opinion, (iii) all Lines (including riser cables) shall be appropriately insulated to prevent excessive electromagnetic fields or radiation, and shall be surrounded by a protective conduit reasonably acceptable to Landlord, (iv) any new or existing Lines servicing the Premises shall comply with all applicable Laws, (v) as a condition to permitting the installation of new Lines, Landlord may require that Tenant remove any existing unused Lines installed by or on behalf of Tenant and located in or serving the Premises, and repair any damage in connection with such removal, and (vi) Tenant shall pay all costs in connection therewith. Landlord reserves the right to require that Tenant remove any Lines located in or serving the Premises which are installed by Tenant in violation of these provisions, or which are at any time in violation of any Laws or represent a dangerous or potentially dangerous condition. Landlord further reserves the right to require that Tenant remove any and all Lines located in or exclusively serving the Premises upon the expiration or earlier termination of this Lease. Notwithstanding the foregoing, Tenant shall identify existing Lines to be removed by Landlord from the Premises prior to the Delivery Date and such Lines shall be removed at no cost to Tenant. The provisions of this Section 5.6 shall survive the expiration or sooner termination of this Lease.

5.7Covenant Against Liens. Tenant shall keep the Project and Premises free from any liens or encumbrances arising out of work performed, materials furnished, or obligations incurred by or on behalf of Tenant or any employee, contractor, agent or invitee of Tenant (collectively, "Tenant's Agents"), and shall protect, defend, indemnify and hold Landlord harmless from and against any claims, liabilities, judgments or costs (including, without limitation, reasonable attorneys' fees and costs) arising out of same or in connection therewith. Tenant shall give Landlord notice at least twenty (20) days prior to the commencement of any work on the Premises which may give rise to a lien on the Premises, Building or Project (or such additional time as may be necessary under applicable laws) to afford Landlord the opportunity of posting and recording appropriate notices of non-responsibility. Tenant shall remove any lien or encumbrance by bond or otherwise within five (5) days after notice by Landlord, and if Tenant shall fail to do so, Landlord may pay the amount necessary to remove such lien or encumbrance, without being responsible for investigating the validity thereof. The amount so paid shall be deemed Additional Rent under this Lease payable within ten (10) business days following demand, without limitation as to other remedies available to Landlord under this Lease. Nothing contained in this Lease shall authorize Tenant to do any act which shall subject Landlord's title to the Building or Premises to any liens or encumbrances whether claimed by operation of law or express or implied contract.

6.1Tenant's Obligations. Tenant shall, at Tenant's sole cost and expense, keep and maintain in good order, condition, and repair at all times during the Lease Term the Premises and every part thereof, including, but not

limited to: (i) all plumbing and sewage facilities (including all sinks, toilets, faucets and drains) within or exclusively serving the Premises; (ii) all ducts, pipes, vents and other parts of the HVAC system within or exclusively serving the Premises; (iii) all improvements, fixtures, equipment, interior walls and window coverings, floors and floor coverings, and ceilings within the Premises; (iv) all windows, doors, entrances, plate glass, showcases and skylights within the Premises (including the replacement of any damaged or broken glass); (v) all electrical facilities and equipment (including all electrical wiring and conduits, fans, vents, exhaust equipment and systems) and all other equipment of any type within or exclusively serving the Premises (including without limitation the Building Systems); (vi) any automatic fire extinguisher equipment located in the Premises; and (vii) any restroom(s) exclusively serving the Premises. With respect to the HVAC system located within or exclusively serving the Premises, Tenant shall maintain continuously throughout the Lease Term a service contract for the maintenance of such HVAC system and all related equipment with a licensed HVAC repair and maintenance contractor reasonably approved by Landlord, which contract provides for the periodic inspection and servicing of such HVAC system and equipment in accordance with the manufacturer's recommendations, but in any event at least once every quarter during the Lease Term. In addition, Tenant shall, at Tenant's own expense, but under the supervision and subject to the prior approval of Landlord, and within any reasonable period of time specified by Landlord, promptly and adequately repair all damage to the Premises and replace or repair all damaged, broken, or worn fixtures and appurtenances, except for damage caused by ordinary wear and tear or beyond the reasonable control of Tenant. In the event that Tenant fails to conduct any maintenance, or to make any repairs required pursuant to this Section 6.1, Landlord may, after written notice to Tenant and Tenant's failure to cure such failure within fifteen (15) days thereafter (provided, however, that if such cure cannot reasonably be effected within such fifteen (15) day period and Tenant begins such cure promptly within such fifteen (15) day period and is pursuing such cure in good faith and with diligence and continuity during such fifteen (15) day period, then, Tenant shall have such additional time as is reasonably necessary to effect such cure), make such repairs and replacements on Tenant's behalf (provided, however, that in the event of an emergency no notice from Landlord shall be required and Landlord shall have the right to immediately make such repairs and replacements on Tenant's behalf), and Tenant shall pay Landlord, within fifteen (15) days following receipt of an invoice, the cost thereof, including a percentage of the cost thereof (to be uniformly established for the Project) sufficient to reimburse Landlord for all overhead, general conditions, fees and other costs or expenses arising from Landlord's involvement with such repairs and replacements. All repairs and replacements required of Tenant pursuant to this Section 6.1 shall be promptly made with new materials of like kind and quality.

6.2Landlord's Obligations. Except as set forth in Section 6.1, above, and subject to the provisions of Articles 11 and 12 of this Lease, Landlord shall repair and maintain in good condition and repair the Building Structure and the Common Areas outside of the Building, except to the extent that such repairs are required due to the negligence or willful misconduct of Tenant; provided, however, that if such repairs are due to the negligence or willful misconduct of Tenant, Landlord shall nevertheless make such repairs at Tenant's expense, or, if covered by Landlord's insurance, Tenant shall only be obligated to pay any deductible in connection therewith. Landlord may, but shall not be required to, enter the Premises at all reasonable times upon at least 24 hours' prior notice to Tenant (which notice, notwithstanding anything to the contrary contained in Section 21.2 of this Lease, may be oral, and which notice shall not be required in the case of an actual or apparent emergency) to make repairs, alterations, improvements or additions to the Premises, the Project or any equipment located in the Project as Landlord shall desire or deem necessary, or as Landlord may be required to perform by governmental or quasi-governmental authority or court order or decree; provided, however, except for (i) emergencies, (ii) repairs, alterations, improvements or additions required by governmental or quasi-governmental authorities or court order or decree, and (iii) repairs which are the obligation of Tenant hereunder, any such entry into the Premises by Landlord shall be performed in a manner so as not to materially interfere with Tenant's use of, or access to, the Premises; provided further that, with respect to items (ii) and (iii) above, Landlord shall use commercially reasonable efforts to not materially interfere with Tenant's use of, or access to, the Premises. Tenant hereby waives any and all rights under and benefits of subsection 1 of Section 1932 and Sections 1941 and 1942 of the California Civil Code or under any similar law, statute, or ordinance now or hereafter in effect.

7.1Hazardous Materials. Landlord and Tenant agree as follows with respect to the existence or use of Hazardous Materials (as defined in Section 7.1.6, below) on the Project:

7.1.1.Hazardous Materials Disclosure Certificate. Upon request by Landlord from time to time, Tenant shall deliver to Landlord an executed Hazardous Materials disclosure statement, substantially in the form reasonably required by Landlord from time to time describing Tenant's then-present use of Hazardous Materials on the Premises, and shall also deliver any other reasonably necessary documents as requested by Landlord. Tenant shall concurrently file with Landlord a copy of any business response plan or inventory required to be maintained and/or

filed with any federal, state or local regulatory agency under any applicable Laws. Landlord and Tenant acknowledge and agree that, as of the date of this Lease, (i) Tenant has fully and accurately completed Landlord's pre-leasing environmental exposures questionnaire (the "Environmental Questionnaire"), and (ii) Tenant has submitted to Landlord a Hazardous Materials Business Plan (the "HMBP Plan" and, together with the Environmental Questionnaire, the "Approved Hazardous Materials"), each as set forth on Exhibit D attached hereto (the "Approved Hazardous Materials Exhibit").

7.1.2.Hazardous Materials Usage. Neither Tenant, nor Tenant’s employees, contractors and subcontractors of any tier, entities with a contractual relationship with Tenant (other than Landlord), or any entity acting as an agent or sub-agent of Tenant, shall be entitled to produce, use, store, generate, transport or dispose of any Hazardous Materials on, in, or about any portion of the Premises, Building or the Project, nor cause or permit any Hazardous Materials to be brought upon, placed, stored, manufactured, generated, blended, handled, recycled, used or released on, in, under or about the Premises (herein referred to as "Hazardous Materials Usage"), without, in each instance, obtaining Landlord’s prior written consent thereto in its sole and absolute discretion, except Tenant shall be entitled to use and/or store only those Hazardous Materials, and their respective quantities, which are (i) specifically listed on the Approved Hazardous Materials Exhibit, and (ii) in full compliance with Laws, and all judicial and administrative decisions pertaining thereto. Tenant shall not be entitled nor permitted to install any tanks under, on or about the Premises, Building or Project for the storage of Hazardous Materials without the express written consent of Landlord, which may be given or withheld in Landlord’s sole and absolute discretion. If any information provided to Landlord by Tenant on the Approved Hazardous Materials Exhibit, or otherwise relating to information concerning Hazardous Materials is false, incomplete, or misleading in any material respect, the same shall be deemed a default by Tenant under this Lease. Landlord’s prior written consent shall be required for any Hazardous Materials use on the Premises not described on the initial Approved Hazardous Materials Exhibit, such consent to be withheld in Landlord’s sole discretion. Any Hazardous Materials Usage by Tenant and Tenant’s Agents after the Effective Date on or about the Project shall strictly comply with all applicable Laws, including all Hazardous Materials Laws now or hereinafter enacted. Such foregoing obligation shall include, without limitation, maintaining, and complying with, all required necessary licenses, certifications, permits and approvals appropriate or required for any Hazardous Materials Usage by Tenant on the Premises. Landlord shall have a continuing right, without obligation, to require Tenant to obtain, and to review and inspect any and all such permits, licenses, certifications and approvals, together with copies of any and all Hazardous Materials management plans and programs, any and all Hazardous Materials risk management and pollution prevention programs, and any and all Hazardous Materials emergency response and employee training programs respecting Tenant’s Hazardous Materials Usage. Upon request of Landlord, Tenant shall deliver to Landlord a narrative description explaining the nature and scope of Tenant’s activities involving Hazardous Materials and demonstrating to Landlord’s satisfaction Tenant's compliance with all Hazardous Materials Laws and the terms of this Lease.

7.1.3.Tests and Inspections. Landlord shall have the right, but not the obligation, upon reasonable requests by Landlord (but in no event less than 24 hours’ written notice), to (i) enter and inspect the Premises, (ii) conduct tests and investigations periodically and from time to time to determine whether Tenant is in compliance with the provisions of this Section 7.1 or to determine if Hazardous Materials are present in, on or about the Project, and (iii) request lists identifying by type and amount all Hazardous Materials used, stored or otherwise located on, under or about any portion of the Premises and/or the Common Areas. The cost of all such inspections, tests and investigations shall be borne by Landlord, unless as a result thereof Landlord reasonably determines that there has been material non-compliance with the provisions of Section 7.1 or contamination has occurred on the Premises and/or Common Areas and that Tenant or any of Tenant's Agents are directly or indirectly responsible in any manner for the non-compliance or contamination, in which case the cost of such inspections, tests and investigations shall be borne by Tenant. The aforementioned rights granted herein to Landlord and its representatives shall not create (a) a duty on Landlord's part to inspect, test, investigate, monitor or otherwise observe the Premises or the activities of Tenant and Tenant's Agents with respect to Hazardous Materials, including without limitation, Tenant's operation, use and any remediation related thereto, or (b) liability on the part of Landlord and its representatives for Tenant's use, storage, disposal or remediation of Hazardous Materials, it being understood that Tenant shall be solely responsible for all liability in connection therewith.

7.1.4.Notice; Cleanup Obligations; Closure and Decommissioning.

Tenant shall give to Landlord immediate verbal and follow-up written notice of any spills, releases, discharges, disposals, emissions, migrations, removals or transportation of Hazardous Materials on, under or about any portion of the Premises, Common Areas or Project in violation of Hazardous Materials Laws as herein defined. Tenant shall promptly forward to Landlord copies of all requests, orders, notices, permits, applications, and other communications and reports received by Tenant from or submitted by Tenant to any federal, state or local regulatory agency with jurisdiction over Tenant's operations of the Premises in connection with the foregoing. To the

extent of any regulatory, judicial or other enforcement action or proceeding in connection with the foregoing is commenced against Tenant, Tenant shall not enter into any settlement, consent decree or other compromise or resolution without first notifying Landlord of Tenant's intention to do so and affording Landlord the opportunity to join and participate, as a party if Landlord so elects, in such proceedings and in no event shall Tenant enter into any consent decree, consent order or other agreements with terms which are binding on Landlord or the Premises without Landlord's prior written consent. Landlord shall have the right to appear at and participate in, any and all judicial or other administrative proceedings concerning any such foregoing claims. Notwithstanding the foregoing, Tenant shall not be required to provide Landlord with any portion(s) of documents containing information of a proprietary nature which, in and of themselves, do not contain a reference to the foregoing spills, releases, discharges, disposals, emissions, migrations, removals or transportation of Hazardous Materials or hazardous activities.

7.1.4.2Cleanup Obligations. Tenant, at its sole cost and expense, covenants and warrants to promptly investigate, clean up, remove, restore and otherwise remediate (including, without limitation, preparation of any feasibility studies or reports and the performance of any and all closures) any spill, release, discharge, disposal, emission, migration or transportation, incident or other consequences of its Hazardous Materials Usage of Hazardous Materials arising from the acts or omissions of Tenant or Tenant's Agents such that the affected portions of the Project and any adjacent property are returned to the condition existing prior to such incident or Tenant's commencement of Hazardous Materials Usage. Tenant shall provide a written certification to Landlord indicating that Tenant has complied with all applicable reporting requirements. Any such investigation, clean up, removal, restoration and other remediation shall only be performed after Tenant has obtained Landlord's prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed. Further, any such investigation, clean up, removal, restoration and other remediation shall be performed in compliance with applicable Laws, the HMBP Plan and in accordance with this Lease. Notwithstanding the foregoing, Tenant shall be entitled to respond immediately to an emergency without first obtaining Landlord's prior written consent.

7.1.4.3Closure and Decommissioning. Tenant, at its sole cost and expense, shall conduct and perform, or cause to be conducted and performed, all closures and decommissioning activity as required by any Hazardous Materials Laws or any federal, state or local regulatory agencies or other governmental authorities having jurisdiction over the Premises and Tenant's activities thereon. All such work undertaken by Tenant, as required herein, shall be performed in such a manner so as to enable Landlord to make full economic use of the Premises and the other portions of the Project after the satisfactory completion of such work.

7.1.5.Indemnity. Tenant shall indemnify, hold harmless, and, at Landlord’s option (with such attorneys as Landlord may approve in advance and in writing), defend Landlord and Landlord’s officers, directors, shareholders, partners, members, managers, employees, contractors, property managers, agents and mortgagees ("Landlord Parties") and other lien holders, from and against any and all “Losses” (hereinafter defined) arising from or related to: (a) any violation or alleged violation by Tenant or any of Tenant’s Agents of any of the Laws, including, without limitation, the Hazardous Materials Laws; (b) any breach of the provisions of this Section 7.1 or any subsection thereof by Tenant or any of Tenant’s Agents; (c) any Hazardous Materials Usage on, about or from the Premises, the Project or Common Areas of any Hazardous Materials approved by Landlord under this Lease, or (d) Landlord's exercise of the "Landlord Cure Right," as that term is defined in Section 21.1 of this Lease, below. The term "Losses" shall mean all claims, demands, expenses, actions, judgments, damages, penalties, fines, liabilities, losses of every kind and nature (including, without limitation, property damage, diminution in value of Landlord’s interest in the Premises or the Project, damages for the loss or restriction on use of any space or amenity within the Building or the Project, damages arising from any adverse impact on marketing space in the Project, sums paid in settlement of claims and any costs and expenses associated with injury, illness or death to or of any person), suits, administrative proceedings, costs and fees, including, but not limited to, attorneys’ and consultants’ fees and expenses, and the costs of cleanup, remediation, removal and restoration. To the actual knowledge of Landlord, except as set forth in reports delivered to Tenant before Tenant’s execution of this Lease, Landlord has no written notices, reports, materials or other written information indicating the presence of Hazardous Materials on the Project or the soil, surface water or groundwater thereof in violation of Hazardous Material Laws. Landlord agrees to indemnify, defend, protect and hold harmless the Tenant from and against any liability, obligation, damage or costs, including without limitation, claims for personal injuries, property damage or regulatory liability arising out of Hazardous Material Laws, and including reasonable attorneys’, consultants and expert’s fees and costs, resulting from any Hazardous Materials which (a) were brought onto the Property or within the Buildings or the Premises by Landlord or a Landlord Party, except to the extent such liability, obligation, damage or costs was a result of an act or omission of Tenant and/or any of Tenant's agents, servants, employees, and independent contractors ("Tenant Parties"), or was proportionately caused, exacerbated or permitted by Tenant or a Tenant Party, or (b) existed on or in the Project or the Premises prior to Tenant’s occupancy, (c) which are caused by the negligence or willful misconduct of Landlord or Landlord Party, or (d) which migrate onto the Premises via air, water or soil at no fault of Tenant. Notwithstanding anything to the contrary contained herein, nothing in this Section 7.1.5 shall be construed to make Tenant responsible for any Hazardous Materials present on the

Premises as of the Delivery Date, or which migrate thereto through air, water, or soil through no fault of Tenant, or are introduced by Landlord, other tenant of the Project or any third party not under Tenant’s control.

7.1.6.Hazardous Materials. As used herein, the term "Hazardous Materials" means any hazardous, radioactive or toxic substance, material or waste which is or becomes regulated by any local governmental authority, the State of California or the United States Government or under any Hazardous Material Laws. The term "Hazardous Materials," includes, without limitation, hazardous radioactive material, radioactive material, mixed waste, petroleum products, asbestos, PCB's, and any material or substance which is (i) now or hereafter listed under Article 9 or defined as hazardous or extremely hazardous pursuant to Article 11 of Title 22 of the California Code of Regulations, Division 4, Chapter 20, (ii) defined as a "hazardous waste" pursuant to Section 1004 of the federal Resource Conservation and Recovery Act, 42 U.S.C. 6901 et seq.

(42 U.S.C. 9601) or (iv) regulated as a radioactive material under Title 17, Division 1, Chapter 5, Subchapter 4 of the California Code or Regulations and Title 10, Code of Federal Regulations, part 20. As used herein, the term "Hazardous Material Laws" shall mean any statute, law, ordinance, or regulation of any governmental body or agency (including the U.S. Environmental Protection Agency, the California Regional Water Quality Control Board, the California Department of Public Health Radiologic Health Branch and the California Department of Toxic Substances Control) which regulates the use, storage, release or disposal of any Hazardous Material.

7.1.7.Removal. Tenant shall cause all Hazardous Materials used in the manufacture of. but which are not included in, a standard finished product which is delivered to Tenant's customers to be promptly relocated to an appropriate and permitted disposal or management facility in accordance with all applicable Laws.

At the expiration or earlier termination of the Lease Term, Tenant, at Tenant's sole cost and expense, shall: (i) cause an environmental assessment of the Premises to be conducted in accordance with this Section 7.1.8; (ii) cause all Hazardous Materials to be removed from the Premises and managed or disposed of in accordance with all Hazardous Materials Laws and as necessary to allow the Premises to be used for any purpose; and (iii) cause to be removed all containers installed or used by Tenant or Tenant’s Agents to store any Hazardous Materials on the Premises, and cause to be repaired any damage to the Premises caused by such removal. In connection with its surrender of the Premises, Tenant shall submit to Landlord, at least one hundred twenty (120) days prior to the expiration date of this Lease (or in the event of an earlier termination of this Lease, as soon as reasonably possible following such termination), an environmental assessment of the Premises by a competent and experienced environmental engineer or engineering firm reasonably satisfactory to Landlord (pursuant to a contract approved by Landlord and providing that Landlord can rely on the environmental assessment), which (i) evidences that the Premises are in a clean and safe condition and free and clear of any Hazardous Materials; and (ii) includes a review of the Premises by an environmental consultant for asbestos, mold, fungus, spores, and other moisture conditions, on-site chemical use, and lead-based paint. If such environmental assessment reveals that remediation or clean-up is required under any Hazardous Materials Laws, Tenant shall submit a remediation plan prepared by a recognized environmental consultant and shall be responsible for all costs of remediation and clean-up, as provided in this Section 7.1.

7.1.9.Pollution Legal Liability Environmental Insurance. Tenant shall obtain and maintain Pollution Legal Liability Environmental Insurance (i) from an insurance carrier with a rating of no less than A-X in Best's Insurance Guide, and (ii) providing commercially reasonable coverage and deductibles (to the extent available) with respect to (i) known and unknown pre-existing conditions; (ii) unknown and later discovered conditions; (iii) on-site and off-site third-party claims for bodily injury or property damage; and (iv) legal defense expenses. The form of the Pollution Legal Liability Environmental Insurance policy shall be reasonably acceptable to Landlord, and the term of such policy shall be at least equal to the then-current Lease Term plus an additional six (6) months. Further, notwithstanding anything to the contrary set forth in this Lease, as a condition precedent to the effectiveness of Tenant's exercise of its right to extend the Lease Term by the Extension Period pursuant to the terms of Exhibit D attached hereto or otherwise, Tenant shall have obtained the policy described in this Section 7.1.9, in accordance with the terms of this Section 7.1.9, including without limitation, that the term of such policy shall be at least equal to the length of the Extension Period plus an additional six (6) months. Landlord, Landlord's lender and such other parties in interest as Landlord reasonably designates shall be named as an additional named insured on the Pollution Legal Liability Environmental Insurance policy by endorsement, and an endorsement shall be issued to the Pollution Legal Liability Environmental Insurance policy that provides the policy cannot be amended, modified, terminated or cancelled by the insured without the prior written consent of Landlord. Any new Pollution Legal Liability Environmental Insurance policy that Tenant obtains shall provide coverage for pollution conditions and unknown claims arising prior to the date such policy was issued (e.g., pre-existing conditions shall be covered).

8.1In General. From and after the Lease Commencement Date, and continuing throughout the remainder of the Lease Term, Tenant will be responsible, at its sole cost and expense, for the following.

8.1.1.The furnishing of all services and utilities which are separately metered to the Premises, including without limitation, electricity, water, gas and sewer, the costs of which shall be paid directly by Tenant to the applicable utility provider. In the event that any service or utility is not separately metered to the Premises, Tenant shall pay Tenant's equitable share of such service or utility, as reasonably determined by Landlord. In the event that any service or utility is submetered to the Premises, Tenant shall pay the costs thereof to Landlord as Additional Rent (and not as an Operating Expense) within ten (10) business days following demand therefor from Landlord.

8.1.2.Landlord shall not provide janitorial services for the Premises. Tenant shall be solely responsible for performing all janitorial (including all trash and recycling services) services and other cleaning of the Premises, all in compliance with applicable Laws. The janitorial and cleaning of the Premises shall be adequate to maintain the Premises in a manner consistent with Class A Life Sciences Projects.

Tenant shall cooperate fully with Landlord at all times and abide by all rules, regulations and requirements that Landlord may reasonably prescribe for the proper functioning and protection of the Building HVAC, electrical, mechanical and plumbing systems. Landlord shall have no obligation to provide any services or utilities to the Building (including, but not limited to heating, ventilation and air-conditioning, electricity, telephone, janitorial and security services).

8.2Overstandard Tenant Use. Tenant's use of electricity shall never exceed the capacity of the feeders to the Project or the risers or wiring installation within the Premises. If Landlord reasonably determines that Tenant is using HVAC in excess amounts as to shorten the useful life of the HVAC equipment serving the Premises, as Landlord shall reasonably determine, then Landlord may charge Tenant (which shall be treated as Additional Rent) for such excess HVAC usage the Landlord’s actual out-of-pocket costs, without any profit to Landlord, but which charge may include the excess depreciation and maintenance as reasonably calculated by Landlord's engineer, and a percentage of such cost to compensate Landlord for its overhead.

8.3Interruption of Use.

8.3.1.In General. Tenant agrees that Landlord shall not be liable for damages, by abatement of Rent (subject to Section 8.3.2 below) or otherwise, for failure to furnish or delay in furnishing any service (including telephone and telecommunication services), or for any diminution in the quality or quantity thereof, when such failure or delay or diminution is occasioned, in whole or in part, by breakage, repairs, replacements, or improvements, by any strike, lockout or other labor trouble, by inability to secure electricity, gas, water, or other fuel at the Building or Project after reasonable effort to do so, by any riot or other dangerous condition, emergency, accident or casualty whatsoever, by act or default of Tenant or other parties, or by any other cause beyond Landlord's reasonable control; and such failures or delays or diminution shall never be deemed to constitute an eviction or disturbance of Tenant's use and possession of the Premises or relieve Tenant from paying Rent or performing any of its obligations under this Lease. Furthermore, Landlord shall not be liable under any circumstances for a loss of, or injury to, property or for injury to, or interference with, Tenant's business, including, without limitation, loss of profits, however occurring, through or in connection with or incidental to a failure to furnish any of the services or utilities as set forth in this Article 8.

8.3.2.Abatement Event. If (i) Landlord fails to provide services required of Landlord under Section 8.1 above, and (ii) such failure causes all or a material portion of the Premises to be untenantable by Tenant and Tenant actually ceases to use all or a material portion of the Premises, (iii) such failure is reasonably within Landlord's ability to cure, and (iv) such failure is not the result of the acts and/or omissions of Tenant and/or other Tenant Parties, then in order to be entitled to receive the benefits of this Section 8.3.2, Tenant must give Landlord notice (the "Abatement Event Notice"), specifying such failure to perform by Landlord (the "Abatement Event"). If Landlord has not commenced to cure such Abatement Event within five (5) business days after the receipt of the Abatement Event Notice and is not otherwise excused from such performance by this Lease, Tenant may, upon written notice to Landlord, immediately abate Base Monthly Rent and Tenant's Share of Project Expenses payable under this Lease for that portion of the Premises rendered untenantable and not actually used by Tenant, for the period beginning on the date five (5) business days after the Abatement Event Notice to the earlier of the date Landlord cures such Abatement Event or the date Tenant recommences the use of such portion of the Premises. Such right to abate Rent shall be Tenant's sole

and exclusive remedy at law or in equity for an Abatement Event. Except as provided in this Section 8.3.2, nothing contained herein shall be interpreted to mean that Tenant is excused from paying Rent due hereunder.

8.4Existing Generator. Tenant shall have the right to use and control the existing approximately 150 KW diesel engine-driven Cummins generator set and related equipment (all such equipment defined collectively as the "Emergency Generator") serving the Premises. The Emergency Generator is being provided in its currently-existing, "as is" condition, and neither Landlord nor any agent of Landlord has made any representation or warranty regarding the condition of the Emergency Generator. Landlord shall not be liable for any damages whatsoever resulting from any failure in operation of the Emergency Generator, or the failure of the Emergency Generator to provide suitable or adequate back-up power, 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, in each case, however occurring, or loss to inventory, scientific research, scientific experiments, laboratory animals, products, specimens, samples, and/or scientific, business, accounting and other records of every kind and description kept at the premises and any and all income derived or derivable therefrom. Tenant shall not be charged any additional rental or other costs for the use of the location in which the Emergency Generator is located. Tenant shall maintain and repair the Emergency Generator in good condition and repair, and in compliance with all applicable laws (including the maintenance of all applicable permits), at Tenant's sole cost and expense during the Lease Term. Tenant's obligations with respect to the Premises, including the insurance and indemnification obligations in this Lease, shall apply to Tenant's use of the Emergency Generator and Tenant shall carry industry standard Boiler and Machinery insurance covering the Emergency Generator. In addition, Tenant shall indemnify, defend, protect, and hold harmless Landlord and the Landlord Parties from any and all loss, cost, damage, expense and liability (including without limitation court costs and reasonable attorneys' fees) incurred in connection with or arising from any cause related to or connected with the use, operation, repair and/or removal of the Emergency Generator and/or any acts, omissions or negligence of Tenant or of any person claiming by, through or under Tenant, or of the contractors, agents, servants, employees, invitees, guests or licensees of Tenant or any such person, in connection with the Emergency Generator, or any breach of the terms of this Section 8.4. The Emergency Generator shall be used by Tenant only during (i) testing and regular maintenance, and (ii) the period of any electrical power outage in the Building. Tenant shall be entitled to operate the Emergency Generator for testing and regular maintenance only upon notice to Landlord and at times reasonably approved by Landlord. The rights granted to Tenant under this Section 8.4 shall be personal to the Original Tenant and any Permitted Transferee (and may not be utilized by or assigned to any other assignee, sublessee or transferee). Following the expiration or earlier termination of this Lease, Tenant shall remove the Generator and all related facilities and equipment (including, without limitation, the Generator's pad and enclosure, if any) prior to the expiration or earlier termination of the Lease, and repair all damage to the Building and/or Project resulting from such removal (including, without limitation, all penetrations) and restore all affected areas to their condition existing prior to the installation of the Generator, all at Tenant's sole cost and expense. The terms set forth in this Section 8.4 shall survive the termination or earlier expiration of this Lease.

8.5Tenant’s Security System. Tenant may, at its own expense, install its own security system (“Tenant’s Security System”) in the Premises; provided, however, that Tenant shall coordinate the installation and operation of Tenant’s Security System with Landlord to assure that Tenant’s Security System is compatible with Landlord’s security system and the Building systems and equipment, and to the extent that Tenant’s Security System is not compatible with Landlord’s security system and the Building systems and equipment, Tenant shall not be entitled to install or operate the Tenant’s Security System. Tenant shall be solely responsible, at Tenant’s sole cost and expense, for the installation, monitoring, operation and removal of Tenant’s Security System. Tenant’s Security System shall be installed by Tenant as an Alteration in accordance with the terms of Article 5 of this Lease.

9.1Tenant's Insurance. Throughout the Lease Term, Tenant shall maintain the following coverages in the following amounts:

9.1.1.Commercial general liability insurance, which may be satisfied through a combination of primary and excess/umbrella insurance, including property damage, against liability for personal injury, bodily injury, death and damage to property (including loss of use thereof) based upon or arising out of Tenant's operations, occupancy or maintenance of the Project and all appurtenances thereto, and including contractual liability coverage insuring Tenant's performance of its obligations under this Lease, including the indemnity agreements set forth in Section 10.1, below, for limits of liability not less than:

9.1.4.Excess/Umbrella Liability with a limit of not less than $4,000,000 scheduling as primary insurance the Commercial General Liability, Auto Liability and Employers Liability.

9.1.5.Form of Policies. The minimum limits of policies of insurance required of Tenant under this Lease shall in no event limit the liability of Tenant under this Lease. Each policy of insurance required to be carried by Tenant pursuant to this Section 9.1, except for Workers Compensation and Employers Liability, shall: (i) name Landlord and such other parties in interest as Landlord reasonably designates as additional insureds; (ii) be primary insurance as to all claims thereunder and provide that the insurer shall be liable for the full amount of the loss up to and including the total amount of liability set forth in the declarations without the right of contribution from any other insurance coverage of Landlord; (iii) be in form and content reasonably satisfactory to Landlord; (iv) be issued by an insurance company having a rating of not less than A-VIII in Best's Insurance Guide or which is otherwise reasonably acceptable to Landlord and licensed or authorized to do business in the State of California; (v) Intentionally Omitted; (vi) specifically cover the liability assumed by Tenant under this Lease, including, but not limited to, Tenant's obligations under Section 10.1 of this Lease; (vii) shall contain a cross liability endorsement; and (viii) shall contain a severability clause.

If Tenant has in full force and effect a blanket policy of liability insurance with the same coverage for the Premises as described above, as well as other coverage of other premises and properties of Tenant, or in which Tenant has some interest, such blanket insurance shall satisfy the requirements of this Section 9.1, provided that the Commercial General Liability insurance under this Section 9.1 contains a per location general aggregate.

9.1.6.Evidence of Insurance. A a certificate of the insurer, certifying that such policy has been issued, providing the coverage required by this Section 9.1, and containing the provisions specified herein, shall be delivered to Landlord prior to the time Tenant or any of Tenant's Agents are first provided access to the Premises, and upon the renewal of such policies. In the event Tenant shall fail to procure such insurance, or to deliver such policies or certificates, Landlord may, at its option, on five (5) days’ notice to Tenant, procure such policies for the account of Tenant, and the cost thereof shall be paid to Landlord within five (5) days after delivery to Tenant of bills therefor.

9.2Landlord's Insurance. Landlord shall maintain a policy or policies of insurance against loss or damage to the Building on a "special form" or "all risk" type insurance form, with customary exceptions, subject to such deductibles and self-insured retentions as Landlord may determine, in an amount equal to at least the full replacement value of the Building. Landlord may insure the Building separately, or with other property owned by Landlord which Landlord elects to insure together under the same policy or policies. Landlord shall have the right, but not the obligation, in its sole and absolute discretion, to obtain insurance for such additional perils as Landlord deems appropriate, including, without limitation, coverage for damage by earthquake and/or flood. Landlord shall not be

required to maintain insurance with respect to any improvements, alterations or fixtures of Tenant located at the Premises.

9.3Release and Waiver of Subrogation. Landlord and Tenant intend that their respective property loss risks shall be borne by reasonable insurance carriers to the extent above provided, and Landlord and Tenant hereby agree to look solely to, and seek recovery only from, their respective insurance carriers in the event of a property loss to the extent that such coverage is agreed to be provided hereunder. The parties each hereby waive all rights and claims against each other for such losses, and waive all rights of subrogation of their respective insurers, provided such waiver of subrogation shall not affect the right to the insured to recover thereunder. The parties agree that their respective insurance policies are now, or shall be, endorsed such that the waiver of subrogation shall not affect the right of the insured to recover thereunder, so long as no material additional premium is charged therefor.

9.4Additional Insurance Obligations. Tenant shall carry and maintain during the entire Lease Term, at Tenant's sole cost and expense, increased amounts of the insurance required to be carried by Tenant pursuant to this Article 9 and such other reasonable types of insurance coverage and in such reasonable amounts covering the Premises and Tenant's operations therein, as may be reasonably requested by Landlord; provided, however, that in no event shall such new or increased amounts or types of insurance exceed that required of comparable tenants by landlords of comparable buildings in San Jose, California.

10.1Indemnification and Waiver. Tenant hereby assumes all risk of damage to property or injury to persons in, upon or about the Premises from any cause whatsoever and agrees that the Landlord Parties shall not be liable for, and are hereby released from any responsibility for, any damage either to person or property or resulting from the loss of use thereof, which damage is sustained by Tenant or by other persons claiming through Tenant. Tenant shall indemnify, defend, protect, and hold harmless the Landlord Parties from and against any and all loss, cost, damage, expense and liability (including without limitation court costs and reasonable attorneys' fees) incurred in connection with or arising from: (a) any causes in, on or about the Premises; (b) the use or occupancy of the Premises by Tenant or any person claiming under Tenant; (c) any activity, work, or thing done, or permitted or suffered by Tenant in or about the Premises; (d) any acts, omission, or negligence of Tenant or Tenant's Agents, in, on or about the Project; (e) any breach, violation, or non-performance by Tenant or any person claiming under Tenant or Tenant's Agents of any term, covenant, or provision of this Lease or any law, ordinance, or governmental requirement of any kind; (f) any injury or damage to the person, property, or business of Tenant or Tenant's Agents entering upon the Premises under the express or implied invitation of Tenant; and (g) the placement of any personal property or other items within the Premises. Should Landlord be named as a defendant in any suit brought against Tenant in connection with or arising out of Tenant's occupancy of the Premises, Tenant shall pay to Landlord its costs and expenses incurred in such suit, including without limitation, its actual professional fees such as appraisers', accountants' and attorneys' fees. Further, Tenant's agreement to indemnify Landlord pursuant to this Section 10.1 is not intended and shall not relieve any insurance carrier of its obligations under policies required to be carried by Tenant pursuant to the provisions of this Lease, to the extent such policies cover the matters subject to Tenant's indemnification obligations; nor shall they supersede any inconsistent agreement of the parties set forth in any other provision of this Lease. Landlord shall indemnify, defend, protect, and hold harmless Tenant and the Tenant Parties from any and all loss, cost, damage, expense and liability (including without limitation reasonable attorneys' fees) arising from (a) the gross negligence or willful misconduct of Landlord in, on or about the Project, except to the extent caused by the negligence or willful misconduct of the Tenant Parties and (b) any breach of this Lease by Landlord. The provisions of this Section 10.1 shall survive the expiration or sooner termination of this Lease with respect to any claims or liability arising in connection with any event occurring prior to such expiration or termination.

10.2Landlord Exculpation. The liability of Landlord or the Landlord Parties to Tenant for any default by Landlord under this Lease or arising in connection herewith or with Landlord's operation, management, leasing, repair, renovation, alteration or any other matter relating to the Project or the Premises shall be limited solely and exclusively to an amount which is equal to the lesser of (a) the interest of Landlord in the Building or (b) the equity interest Landlord would have in the Building if the Building were encumbered by third-party debt in an amount equal to eighty percent (80%) of the value of the Building (as such value is determined by an appraisal of the building by an MAI appraiser selected by Landlord), provided that in no event shall such liability extend to any sales or insurance proceeds received by Landlord or the Landlord Parties in connection with the Project, Building or Premises. Neither Landlord, nor any of the Landlord Parties shall have any personal liability therefor, and Tenant hereby expressly waives and releases such personal liability on behalf of itself and all persons claiming by, through or under Tenant. The limitations of liability contained in this Section 10.2 shall inure to the benefit of Landlord's and the Landlord Parties' present and

future partners, beneficiaries, officers, directors, trustees, shareholders, agents and employees, and their respective partners, heirs, successors and assigns. Under no circumstances shall any present or future partner of Landlord (if Landlord is a partnership), or trustee or beneficiary (if Landlord or any partner of Landlord is a trust), have any liability for the performance of Landlord's obligations under this Lease. Notwithstanding any contrary provision herein, neither Landlord nor the Landlord Parties shall be liable under any circumstances for any 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, in each case, however occurring.

11.1Landlord's Duty to Restore. Subject to the provisions of Section 11.2, below, if the Premises are damaged by fire or other casualty, Landlord shall promptly and diligently restore the Base Building to substantially the same condition as existed prior to the casualty, except for modifications required by zoning and building codes and other laws, or by the holder of a mortgage on the Building or Project, or any other modifications to the Common Areas deemed desirable by Landlord to the extent the same are consistent with Class A Life Sciences Projects. All insurance proceeds available from the fire and property damage insurance carried by Landlord shall be paid to and become the property of Landlord. If this Lease is terminated pursuant to Section 11.2, below, then all insurance proceeds available from the fire and property damage insurance carried by Tenant and all insurance covering the Original Improvements and any Alterations, but excluding proceeds for trade fixtures, merchandise, signs and other personal property of Tenant, shall be disbursed and paid to Landlord. If this Lease is not terminated pursuant to Section 11.2, below, then Tenant shall forthwith replace or fully repair all Original Improvements and any Alterations made in the Premises by Tenant, and replace its furniture, fixtures and equipment in the Premises.

11.2Landlord's Right to Terminate. Notwithstanding Section 11.1 above, Landlord shall have the right, upon written notice to Tenant within sixty (60) days following the date of the casualty, to terminate this Lease in the event any of the following occurs:

11.2.1.Damage From Insured Peril. The Building or Project is damaged by fire or other peril, and the cost of repair is covered by insurance and the estimated time for repair and restoration of same exceeds two hundred seventy (270) days after the date of such damage;

11.2.2.Damage From Uninsured Peril. The Building or Project is damaged, and the cost of repair is not covered by insurance (including deductible amounts); provided, however, that any election by Landlord to terminate this Lease pursuant to this Section 11.2.2 shall be null and void if one or more tenants of the Project agree in writing to pay the amount by which the cost to restore the Building or Project, as applicable, exceeds such amount, and such party(ies) subsequently deposit such amount with Landlord within thirty (30) days after Landlord has notified Tenant of its election to terminate this Lease;

11.2.3.Damage Near End of Term. The Premises are damaged by any peril during the last twelve (12) months of the Lease Term and the estimated cost to restore the Premises equals or exceeds an amount equal to six (6) times the then-applicable Base Monthly Rent; provided, however, that any election by Landlord to terminate this Lease pursuant to this Section 11.2.3 shall be null and void if Tenant, at the time of such damage, has a then valid option to extend the Lease Term pursuant to this Lease, and Tenant exercises such option to extend the Lease Term within fifteen (15) days following the date of such damage; or

11.2.4.Restrictions on Restoration. The Building or Project is damaged by any peril and, because of the Laws then in effect and applicable to the Project, the Building or Project, as applicable (i) cannot be restored by Landlord at reasonable cost to substantially the same condition as existed prior to such damage, or (ii) cannot be used for the same use being made thereof prior to such damage if the same is restored as required by this Article 11.

11.3Tenant's Right to Terminate. If the Premises are damaged by any peril and Landlord does not elect to terminate this Lease, or is not entitled to terminate this Lease pursuant to Section 11.2, above, then as soon as reasonably practicable following the date of such damage, Landlord shall provide Tenant with written notice stating the estimated time for repair or restoration following the issuance of a building permit for such work. Tenant shall have the right, upon written notice to Landlord within seven (7) days following receipt of such written notice from Landlord, to terminate this Lease in the event any of the following occurs:

11.3.1.Major Damage. The Premises are damaged by any peril and the time stated in Landlord's notice for the repair and restoration of the Premises exceeds two hundred-seventy (270) days following the issuance of a building permit; or

11.3.2.Damage Near End of Term. The Premises are damaged by any peril during the last twelve (12) months of the Lease Term and the time stated in Landlord's notice for the repair and restoration of the Premises exceeds ninety (90) days following the issuance of a building permit.

11.4Abatement of Rent. In the event of damage to the Premises which does not result in the termination of this Lease, the Base Monthly Rent and the Additional Rent payable hereunder shall be temporarily abated during the period of restoration in proportion to the degree to which Tenant's use of the Premises is impaired during such period of restoration; provided, however, the amount of Base Monthly Rent and Additional Rent abated pursuant to this Section 11.4 shall in no event exceed the amount of loss of rental income insurance proceeds actually received by Landlord. Tenant shall not be entitled to any compensation or damages from Landlord for loss of Tenant's business or property, or for any inconvenience or annoyance caused by such damage or restoration.

11.5Waiver of Statutory Provisions. The provisions of this Lease, including this Article 11, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises, the Building or the Project, and any statute or regulation of the State of California, including, without limitation, Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or obligations concerning damage or destruction in the absence of an express agreement between the parties, and any other statute or regulation, now or hereafter in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises, the Building or the Project.

12.1Landlord's Termination Right. If the whole or any part of the Premises, Building or Project shall be taken by power of eminent domain or condemned by any competent authority for any public or quasi-public use or purpose, or if Landlord shall grant a deed or other instrument in lieu of such taking by eminent domain or condemnation, Landlord shall have the right to terminate this Lease effective as of the date possession is required to be surrendered to the condemning authority.

12.2Tenant's Termination Right. If, as a result of any taking by means of the exercise of the power of eminent domain (including any voluntary sale or transfer by Landlord to any condemnor under threat of condemnation), (i) twenty-five percent (25%) or more of the rentable square feet of the Premises is taken and the part of the Premises that remains cannot be restored within a reasonable period of time following the date possession is required to be surrendered to the authority, and the continued operation of the Tenant's business from the Premises is thereby materially impaired, or (ii) as a result of any taking Tenant's access to the Premises is materially impaired, then Tenant shall have the right to terminate this Lease effective as of the date possession is required to be surrendered to the condemning authority.

12.3Restoration and Abatement of Rent. If any part of the Premises or the Common Areas is taken by condemnation and this Lease is not terminated, then Landlord shall, to the extent of the condemnation proceeds, restore the remaining portion of the Premises or Common Areas necessary for Tenant to reasonably operate Tenant's business from the Premises. Thereafter, subject to Section 12.4 below, as of the date possession is required to be surrendered to the authority, the Base Monthly Rent and Additional Rent payable hereunder shall be reduced in the same proportion that the number of rentable square feet of the Premises so taken (less any addition thereto by reason of any restoration or reconstruction by Landlord) bears to the original number of rentable square feet in the Premises.

12.4Temporary Taking. If any portion of the Premises is temporarily taken for a period of one hundred eighty (180) days or less (a "Temporary Taking"), this Lease shall remain in effect and the provisions of Sections 12.1 through 12.3, above, shall not apply. If any Temporary Taking extends beyond the natural expiration of the Lease Term, and such taking materially and adversely affects Tenant's ability to use the Premises for the Permitted Use, then Tenant shall have the right to terminate this Lease, effective on the date possession is required to be surrendered to the condemning authority.

12.5Award. The entire award or compensation made as a result of any condemnation proceeding shall belong to and be the property of Landlord, and Tenant hereby assigns to Landlord all of its right, title and interest in any such award; provided, however, that Tenant shall be entitled to recover from the condemning authority such

compensation as may be separately awarded by the condemning authority to Tenant or recoverable from the condemning authority by Tenant in its own right for the taking of trade fixtures and equipment owned by Tenant and for the expense of removing and relocating its trade fixtures and equipment, so long as the award made to Landlord is not thereby reduced. The rights of Landlord and Tenant regarding any condemnation shall be determined as provided in this Article 12, and each party hereby waives the provisions of California Code of Civil Procedure Section 1265.130 and the provisions of any similar law hereinafter enacted.

13.1Events of Default. Tenant shall be in default of this Lease if any of the following events occurs (each, an "Event of Tenant's Default"):

13.1.1.Any failure by Tenant to pay any installment of Rent or any other charges required to be paid under this Lease when due, and such failure is not cured within three (3) business days after delivery of written notice to Tenant from Landlord specifying such failure to pay; or

13.1.2.Except where a specific time period is otherwise set forth for Tenant's performance in this Lease, in which event the failure to perform by Tenant within such time period shall be an Event of Tenant's Default under this Section 13.1, any failure by Tenant to observe or perform any term, covenant, or condition of this Lease, where such failure continues for more than thirty (30) days after written notice from Landlord to Tenant specifying the nature of such failure; provided that if the nature of such default is such that the same cannot reasonably be cured within a thirty (30) day period, Tenant shall not be deemed to be in default if it diligently commences such cure within such period and thereafter diligently and continuously proceeds to rectify and cure such default; or

13.1.3.Any abandonment of the Premises (pursuant to Section 1951.35 of the California Civil code) by Tenant; or

13.1.4.The failure by Tenant to observe or perform according to the provisions of Articles 4, 7, 14, 17 or 18 of this Lease, or any breach by Tenant of the representations and warranties set forth in Section 21.28 of this Lease, or the failure by Tenant to observe or perform any other provision, covenant or condition of this Lease which failure, because of the character of such provision, covenant or condition, would immediately jeopardize Landlord's interest, where such failure continues for more than two (2) business days after notice from Landlord.

Any written notice of an Event of Tenant's Default sent by Landlord to Tenant shall be in lieu of, and not in addition to, any termination notice required under applicable statutory or regulatory provisions (and no further notice shall be required should Landlord elect to terminate this Lease as set forth below).

13.2Landlord's Remedies. Upon the occurrence of any Event of Tenant's Default, Landlord shall have, in addition to any other remedies available to Landlord at law or in equity (all of which remedies shall be distinct, separate and cumulative), the option to pursue any one or more of the following remedies, each and all of which shall be cumulative and nonexclusive, without any notice or demand whatsoever:

13.2.1.Terminate this Lease, in which event Tenant shall immediately surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and take possession of the Premises and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without being liable for prosecution or any claim or damages therefor; and Landlord may recover from Tenant the following:

13.2.1.1The worth at the time of award of any unpaid rent which has been earned at the time of such termination; plus

13.2.1.2The worth at the time of award of the amount by which the unpaid rent which would have been earned after termination until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

13.2.1.3The worth at the time of award of the amount by which the unpaid rent for the balance of the Lease Term after the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

13.2.1.4Any 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; and

13.2.1.5At Landlord's election, such other reasonable amounts in addition to or in lieu of the foregoing as may be permitted from time to time by applicable law.

The term "rent" as used in this Section 13.2 shall be deemed to be and to mean all sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or to others. As used in Sections 13.2.1.1 and 13.2.1.2, above, the "worth at the time of award" shall be computed by allowing interest at the Agreed Interest Rate, but in no case greater than the maximum amount of such interest permitted by law. As used in Section 13.2.1.3 above, the "worth at the time of award" shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one percent (1%).

13.2.2.Landlord shall have the remedy described in 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). Accordingly, if Landlord does not elect to terminate this Lease on account of any Event of Tenant's Default, Landlord may, from time to time, without terminating this Lease, enforce all of its rights and remedies under this Lease, including the right to recover all rent as it becomes due.

13.2.3.Landlord shall at all times have the rights and remedies (which shall be cumulative with each other and cumulative and in addition to those rights and remedies available under Sections 13.2.1 and 13.2.2, above, or any law or other provision of this Lease), without prior demand or notice except as required by applicable law, to seek any declaratory, injunctive or other equitable relief, and specifically enforce this Lease, or restrain or enjoin a violation or breach of any provision hereof.

13.3Subleases of Tenant. If Landlord elects to terminate this Lease on account of any Event of Tenant's Default, as set forth in this Article 13, then Landlord shall have the right, at Landlord's option in its sole discretion (i) to terminate any and all assignments, subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises, in which event Landlord shall have the right to repossess such affected portions of the Premises by any lawful means, or (ii) to succeed to Tenant's interest in any or all such assignments, subleases, licenses, concessions or arrangements, in which event Landlord may require any assignees, sublessees, licensees or other parties thereunder to attorn to and recognize Landlord as its assignor, sublessor, licensor, concessionaire or transferor thereunder. In the event of Landlord's election to succeed to Tenant's interest in any such assignments, subleases, licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder.

13.4Efforts to Relet. No re-entry or repossession, repairs, maintenance, changes, alterations and additions, reletting, appointment of a receiver to protect Landlord's interests hereunder, or any other action or omission by Landlord shall be construed as an election by Landlord to terminate this Lease or Tenant's right to possession, or to accept a surrender of the Premises, nor shall same operate to release Tenant in whole or in part from any of Tenant's obligations hereunder, unless express written notice of such intention is sent by Landlord to Tenant. Tenant hereby irrevocably waives any right otherwise available under any law to redeem or reinstate this Lease.

14.1Transfers. Tenant shall not do any of the following (collectively referred to herein as a "Transfer", and any person to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a "Transferee"), whether voluntarily, involuntarily, by operation of law or otherwise without the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed: (i) sublet all or any portion of the Premises; (ii) assign or permit any assignment of its interest in this Lease; (iii) mortgage, pledge, hypothecate, encumber or permit any lien to attach to this Lease; (iv) enter into any license or concession agreements or otherwise permit the use or occupancy of the Premises or any part thereof by any persons other than Tenant and its employees or contractors; or (v) materially amend or modify an assignment, sublease or other transfer that has been previously approved by Landlord. Tenant shall reimburse Landlord for all reasonable costs not to exceed $5,000 for a Transfer in the ordinary course of business, including attorneys' fees, incurred by Landlord in connection with the evaluation, processing, and/or documentation of any requested Transfer, whether or not Landlord's consent to such Transfer is granted, within thirty (30) days of receipt of demand therefor. Any Transfer approved by Landlord pursuant to this Article 14 shall not become effective until Tenant has delivered to Landlord a fully-executed version of the document

evidencing such Transfer which document shall: (a) be in a form reasonably approved in advance by Landlord, (b) contain substantially the same terms and conditions as stated in Tenant's request for such Transfer set forth above, and (c) in the case of an assignment of the Lease, contain the agreement of the proposed Transferee to assume all obligations of Tenant under this Lease arising after the effective date of such Transfer, and to remain jointly and severally liable therefor with Tenant. Any attempted Transfer without Landlord's prior consent shall constitute an Event of Tenant's Default and shall, at Landlord's option, be null, void and of no further force or effect. Landlord's consent to any one Transfer shall not constitute a waiver of the provisions of this Section 14.1 as to any subsequent Transfer or a consent to any subsequent Transfer. No Transfer, whether made with or without the consent of Landlord, shall relieve Tenant of its personal and primary obligation to pay the Rent due hereunder, or to perform all of the other obligations to be performed by Tenant hereunder. The acceptance of any payment of Rent by Landlord from any person or entity shall not be deemed to be a waiver by Landlord of any provision of this Lease or to be a consent to any Transfer.

14.2Procedure. At least twenty-one (21) days, but not more than one hundred eighty (180) days, before a proposed Transfer is to become effective, Tenant shall give Landlord written notice (a "Transfer Notice") of the proposed terms of such Transfer, which Transfer Notice shall include the following information: (i) the proposed effective date of the Transfer; (ii) a description of the portion of the Premises to be transferred (the "Subject Space"); (iii) the name and legal composition of the proposed Transferee; (iv) all of the terms of the proposed Transfer and the consideration therefor, including calculation of the Transfer Premium, as that term is defined in Section 14.4 below, in connection with such Transfer; (v) current financial statements of the proposed Transferee certified by an officer, partner or owner thereof, covering the current year and the preceding two (2) years if the same exist, all of which statements are prepared in accordance with generally accepted accounting principles; (vi) the nature of the proposed Transferee's business to be carried on in the Premises; and (vii) an accurately filled out response to Landlord's standard hazardous materials questionnaire. In addition, Tenant shall promptly provide to Landlord such other information regarding the proposed Transfer and/or Transferee as may be reasonably requested by Landlord. Landlord shall respond in writing to a Transfer Notice within twenty-one (21) days following Landlord's receipt of such notice and all required accompanying information and documentation.

14.3Landlord's Consent. Landlord shall not unreasonably withhold its consent to any proposed Transfer of the Subject Space to the Transferee on the terms specified in the Transfer Notice. Without limitation as to other reasonable grounds for withholding consent, the parties hereby agree that it shall be reasonable under this Lease and under any applicable law for Landlord to withhold consent to any proposed Transfer where one or more of the following apply:

14.3.1.An Event of Tenant's Default has occurred or is then occurring;

14.3.2.The Transferee is of a character or reputation, or is engaged in a business, which is not consistent with the quality of the Building or the Project;

14.3.3.The Transferee intends to use the Subject Space for purposes which are not permitted under this Lease, or for a use that is likely to be subject to compliance with additional laws or other governmental requirements beyond those to which the Permitted Use is subject;

14.3.4.The Transferee is either a governmental agency or instrumentality thereof;

14.3.5.The Transferee is not a party of reasonable financial worth and/or financial stability in light of the responsibilities to be undertaken in connection with the Transfer on the date consent is requested;

14.3.6.The proposed Transfer would cause a violation of another lease for space in the Project, or would give an occupant of the Project a right to cancel its lease; or

14.3.7.The proposed Transferee will use, store or dispose of Hazardous Materials in or about the Premises of a type, nature or quantity not acceptable to Landlord in Landlord's sole discretion.

If Landlord consents to any Transfer pursuant to the terms of this Section 14.3 (and does not exercise any recapture rights Landlord may have under Section 14.5 of this Lease), Tenant may within six (6) months after Landlord's consent, but not later than the expiration of said six (6)-month period, enter into such Transfer of the Premises or portion thereof, upon substantially the same terms and conditions as are set forth in the Transfer Notice furnished by Tenant to Landlord pursuant to Section 14.2 of this Lease, provided that if there are any changes in the terms and conditions from those specified in the Transfer Notice (i) such that Landlord would initially have been

entitled to refuse its consent to such Transfer under this Section 14.3, or (ii) which would cause the proposed Transfer to be more favorable to the Transferee than the terms set forth in Tenant's original Transfer Notice, Tenant shall again submit the Transfer to Landlord for its approval and other action under this Article 14. Notwithstanding anything to the contrary in this Lease, if Tenant or any proposed Transferee claims that Landlord has unreasonably withheld or delayed its consent under Section 14.3 or otherwise has breached or acted unreasonably under this Article 14, their sole remedies shall be a declaratory judgment and an injunction for the relief sought, and Tenant hereby waives the provisions of Section 1995.310 of the California Civil Code, or any successor statute, and all other remedies, including, without limitation, any right at law or equity to terminate this Lease, on its own behalf and, to the extent permitted under all applicable laws, on behalf of the proposed Transferee. Tenant shall indemnify, defend and hold harmless Landlord from any and all liability, losses, claims, damages, costs, expenses, causes of action and proceedings involving any third party or parties (including without limitation Tenant's proposed subtenant or assignee) who claim they were damaged by Landlord's wrongful withholding or conditioning of Landlord's consent.

14.4Transfer Premium. If Landlord consents to a Transfer, as a condition thereto which the parties hereby agree is reasonable, Tenant shall pay to Landlord fifty percent (50%) of any Transfer Premium received by Tenant from such Transferee. "Transfer Premium" shall mean all rent, additional rent or other consideration payable by such Transferee in connection with the Transfer in excess of the Base Monthly Rent and Additional Rent payable by Tenant under this Lease during the term of the Transfer on a per rentable square foot basis if less than all of the Premises is transferred, after deducting the reasonable expenses incurred by Tenant for (i) any changes, alterations and improvements to the Premises in connection with the Transfer, (ii) any free base rent reasonably provided to the Transferee in connection with the Transfer (provided that such free rent shall be deducted only to the extent the same is included in the calculation of total consideration payable by such Transferee), and (iii) any brokerage commissions in connection with the Transfer and (iv) legal fees reasonably incurred in connection with the Transfer (collectively, "Tenant's Subleasing Costs"). "Transfer Premium" shall also include, but not be limited to, key money, bonus money or other cash consideration paid by Transferee to Tenant in connection with such Transfer, and any payment in excess of fair market value for services rendered by Tenant to Transferee or for assets, fixtures, inventory, equipment, or furniture transferred by Tenant to Transferee in connection with such Transfer. Landlord shall make a determination of the amount of Landlord's applicable share of the Transfer Premium on a monthly basis as rent or other consideration is paid by Transferee to Tenant under the Transfer. For purposes of calculating the Transfer Premium on a monthly basis, Tenant's Subleasing Costs shall be deemed to be expended by Tenant in equal monthly amounts over the entire term of the Transfer.

14.5Intentionally Omitted.

14.6Effect of Transfer. If Landlord consents to a Transfer, then (i) the terms and conditions of this Lease shall in no way be deemed to have been waived or modified; (ii) such consent shall not be deemed consent to any further Transfer by either Tenant or a Transferee; (iii) Tenant shall deliver to Landlord, promptly after execution, an original executed copy of all documentation pertaining to the Transfer in form and content reasonably acceptable to Landlord; (iv) Tenant shall furnish upon Landlord's request a complete statement, certified by an independent certified public accountant, or Tenant's chief financial officer, setting forth in detail the computation of any Transfer Premium Tenant has derived and shall derive from such Transfer; and (v) no Transfer relating to this Lease or agreement entered into with respect thereto, whether with or without Landlord's consent, shall relieve Tenant or any guarantor of the Lease from any liability under this Lease, including, without limitation, in connection with the Subject Space, and, in the event of a Transfer of Tenant's entire interest in this Lease, the liability of Tenant and such Transferee shall be joint and several. Landlord or its authorized representatives shall have the right at all reasonable times to audit the books, records and papers of Tenant relating to any Transfer, and shall have the right to make copies thereof. If the Transfer Premium respecting any Transfer shall be found understated, Tenant shall, within thirty (30) days after demand, pay the deficiency, and if understated by more than five percent (5%), Tenant shall pay Landlord's costs of such audit.

14.7Occurrence of Default. Any Transfer hereunder shall be subordinate and subject to the provisions of this Lease, and if this Lease shall be terminated during the term of any Transfer, then Landlord shall have all of the rights set forth in Section 13.3 of this Lease with respect to such Transfer. In addition, if Tenant shall be in default under this Lease, then Landlord is hereby irrevocably authorized, as Tenant's agent and attorney-in-fact, to direct any Transferee to make all payments under or in connection with a Transfer directly to Landlord (which payments Landlord shall apply towards Tenant's obligations under this Lease) until such default is cured. Such Transferee shall rely on any representation by Landlord that Tenant is in default hereunder, without any need for confirmation thereof by Tenant. Upon any assignment, the assignee shall assume in writing all obligations and covenants of Tenant thereafter to be performed or observed under this Lease. No collection or acceptance of rent by Landlord from any Transferee shall be deemed a waiver of any provision of this Article 14 or the approval of any Transferee or a release of Tenant from any obligation under this Lease, whether theretofore or thereafter accruing. In no event shall Landlord's enforcement of any provision of this Lease against any Transferee be deemed a waiver of Landlord's right to enforce any term of this Lease

against Tenant or any other person. If Tenant's obligations hereunder have been guaranteed, Landlord's consent to any Transfer shall not be effective unless the guarantor also consents to such Transfer.

14.8Deemed Transfers. For purposes of this Lease, the term "Transfer" shall also include (i) if Tenant is a partnership, the withdrawal or change, voluntary, involuntary or by operation of law, of fifty percent (50%) or more of the partners, or transfer of fifty percent (50%) or more of partnership interests, within a twelve (12)-month period, or the dissolution of the partnership without immediate reconstitution thereof, and (ii) if Tenant is a closely held corporation (i.e., whose stock is not publicly held and not traded through an exchange or over the counter), (A) the dissolution, merger, consolidation or other reorganization of Tenant or (B) the sale or other transfer of an aggregate of fifty percent (50%) or more of the voting shares of Tenant (other than to immediate family members by reason of gift or death), within a twelve (12)-month period, or (C) the sale, mortgage, hypothecation or pledge of an aggregate of fifty percent (50%) or more of the value of the unencumbered assets of Tenant within a twelve (12)-month period.

14.9Permitted Transfers. Notwithstanding anything to the contrary contained in this Lease, an assignment or subletting of all or a portion of the Premises: (a) to a corporation or other business entity ("successor corporation") into or with which Tenant shall be merged, consolidated, reorganized (other than a reorganization as a result of bankruptcy), recapitalized or acquired or to which substantially all of the assets of Tenant may be transferred, and provided that the successor corporation shall assume in writing all of the obligations and liabilities of Tenant under this Lease; or (b) to a corporation or other business entity (herein sometimes referred to as a "related corporation") which shall control, be controlled by or be under common control with Tenant; or (c) as a result of a sale or other transfer of corporate shares of capital stock (or any member interest if Tenant is a limited liability company) in Tenant in connection with either a bona fide financing for the benefit of Tenant or an initial public offering of Tenant’s stock on a nationally-recognized stock exchange, or (d) transfers of shares of stock or membership interests in Tenant which result in a change in control over a period in excess of twelve (12) consecutive months, shall not be deemed a Transfer requiring Landlord's consent under this Article 14 (any such assignee or sublessee described in items (a) through (d) of this Section 14.9 hereinafter referred to as a "Permitted Transferee"), provided that (i) Tenant notifies Landlord at least twenty-one (21) days prior to any such assignment or sublease and promptly supplies Landlord with any documents or information reasonably requested by Landlord regarding such transfer or transferee as set forth above, (ii) such assignment or sublease is not a subterfuge by Tenant to avoid its obligations under this Lease, it being understood that such Transferee shall thereafter become liable under this Lease, on a joint and several basis, with Tenant, (iii) any transferee under this Section 14.9 shall be of a character and reputation consistent with the quality of the Building, and (iv) in the case of an assignment, such successor entity or related entity, as applicable, together with the Original Tenant if Original Tenant is a surviving entity and remains liable under this Lease, shall have a tangible net worth (not including goodwill as an asset) computed in accordance with generally accepted accounting principles (excluding goodwill as an asset) ("Net Worth"), at least equal to Tenant's Net Worth either immediately before the Transfer or as of the date of this Lease, whichever is greater. An assignee of Tenant's entire interest in this Lease who qualifies as a Permitted Transferee may also be referred to herein as a "Permitted Transferee Assignee." "Control," as used in this Section 14.9, shall mean the ownership, directly or indirectly, of at least fifty-one percent (51%) of the voting securities of, or possession of the right to vote, in the ordinary direction of its affairs, of at least fifty-one percent (51%) of the voting interest in, any person or entity.

14.10Reasonable Restriction. The restrictions on Transfer described in this Lease are acknowledged by Tenant to be reasonable for all purposes, including, without limitation, the provisions of California Civil Code Section 1951.4(b)(2). Tenant expressly waives any rights which it might otherwise be deemed to possess pursuant to applicable law, including, without limitation, California Civil Code Section 1997.040, to limit any remedy of Landlord pursuant to California Civil Code Section 1951.2 or 1951.4 by means of proof that enforcement of a restriction on use of the Premises would be unreasonable.

15.1Surrender of Premises. Upon the expiration or sooner termination of this Lease, Tenant shall vacate and surrender the Premises to Landlord in as good condition and repair as existed upon Landlord's delivery of the Premises to Tenant, reasonable wear and tear and repairs which are specifically made the responsibility of Landlord hereunder excepted. Notwithstanding the foregoing, prior to Tenant's surrender of the Premises to Landlord, at the expiration or earlier termination of this Lease, Tenant shall, at its sole cost and expense, cause the following to be done: (i) all interior walls shall be painted or cleaned, as necessary; (ii) all tiled floors shall be cleaned; (iii) all carpets shall be cleaned and shampooed; (iv) all broken, marred, stained or nonconforming acoustical ceiling tiles shall be replaced; (v) all debris, rubbish, such items of furniture, equipment, business and trade fixtures, free-standing cabinet work, movable partitions and other articles of personal property owned by Tenant or installed or placed by Tenant at its

expense in the Premises shall be removed; and (vi) the plumbing and electrical systems and lighting shall be placed in good order and repair (including replacement of any burned out, discolored or broken light bulbs, ballasts, or lenses). In addition, at Landlord's request, Tenant shall, prior to Tenant's surrender of the Premises to Landlord, (i) remove any Alterations which Tenant is required to remove pursuant to Section 5.5 and repair all damage caused by such removal, and (ii) return the Premises or any part thereof to its original configuration existing as of the time the Premises were delivered by Landlord to Tenant, except as provided in this Lease.

15.2Environmental Assessment. In connection with its surrender of the Premises, Tenant shall submit to Landlord an environmental assessment pursuant to the terms of Section 7.1.8, above. If such environmental assessment reveals that remediation or clean-up is required under any Hazardous Materials Laws, Tenant shall submit a remediation plan prepared by a recognized environmental consultant and shall be responsible for all costs of remediation and clean-up, as provided in Section 7.1, above.

16.1In General. If Tenant holds over in the Premises or any part thereof after the expiration or earlier termination of this Lease, such tenancy shall not constitute a renewal or extension of the Lease and shall be construed to be a tenancy from month to month on the same terms and conditions contained herein, except that Base Monthly Rent shall be payable at an amount equal to two (2) times the Base Monthly Rent payable during the last full calendar month of the Lease Term. Nothing contained in this Article 16 shall be construed as consent by Landlord to any holding over by Tenant, and Landlord expressly reserves the right to require Tenant to surrender possession of the Premises to Landlord as provided in this Lease upon the expiration or other termination of this Lease. The provisions of this Article 16 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided under this Lease or at law. If Tenant holds over without Landlord's express written consent, and tenders payment of rent for any period beyond the expiration or earlier termination of the Lease Term by way of check (whether directly to Landlord, its agents, or to a lock box) or wire transfer, Tenant acknowledges and agrees that the cashing of such check or acceptance of such wire shall be considered inadvertent and not be construed as creating a month-to-month tenancy, provided Landlord refunds such payment to Tenant promptly upon learning that such check has been cashed or wire transfer received. Additionally, in the event that upon the expiration or earlier termination of the Lease, Tenant has not fulfilled its obligation with respect to restoration, repairs and cleanup of the Premises or any other Tenant obligations as set forth in this Lease, then Landlord shall have the right to perform any such obligations as it deems necessary at Tenant's sole cost and expense, and any time required by Landlord to complete such obligations shall be considered a period of holding over and the terms of this Article 16 shall apply. Tenant acknowledges that any holding over in the Premises by Tenant without Landlord's express written consent may compromise or otherwise affect Landlord's ability to enter into new leases with prospective tenants regarding the Premises. Therefore, if Tenant fails to vacate and deliver the Premises to Landlord within thirty (30) days following the expiration or earlier termination of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from and against any and all claims and liability resulting from such failure, including, without limiting the generality of the foregoing, any claims made by any succeeding tenant founded upon such failure to vacate and deliver, and any losses suffered by Landlord, including lost profits, resulting therefrom. Tenant agrees that any proceedings necessary to recover possession of the Premises from Tenant, whether before or after the expiration or earlier termination of this Lease, shall be considered an action to enforce the terms of this Lease for purposes of the awarding of any attorneys' fees in connection therewith.

16.2Short Term Lease Extension. Notwithstanding any provision to the contrary in this Article 16, Tenant shall have the right, upon the expiration of the Lease Term, to extend the Lease Expiration Date for the entire Premises then leased by Tenant for a period of up to three (3) months, by giving written notice to Landlord of such election not less than two (2) months prior to the scheduled Lease Expiration Date. Upon such election, the Lease Term for the entire Premises then leased by Tenant shall be extended for the length of time set forth in Tenant's written notice (not to exceed three (3) months) on all the terms and conditions of this Lease (the "Approved Holdover Period"), provided that the Base Monthly Rent payable during the Approved Holdover Period shall be equal to 150% of the Base Monthly Rent payable during the last rental period of the Lease Term under this Lease. The terms of the penultimate sentence of Section 16.1 shall apply with respect to any holdover following the expiration of the Approved Holdover Period.

At all times during the Lease Term, Tenant shall, within ten (10) business days following receipt of written request from Landlord, execute and deliver to Landlord an estoppel certificate in the form attached hereto as Exhibit E ("Estoppel Certificate"). Tenant's failure to timely deliver an executed Estoppel Certificate within said ten (10) business day period shall constitute an acknowledgement by Tenant that the statements included in the Estoppel Certificate are true and correct without exception. At any time during the Lease Term, but no more than once per calendar year except in connection with a sale, financing or refinancing of the Project or Building, Tenant’s request for Landlord consent to an Alteration or a Transfer, or if an Event of Default has occurred, Landlord may require Tenant to provide Landlord with Tenant's current financial statement and the financial statements covering the two (2) year period prior to the date of such current financial statement. Such statements shall be prepared in accordance with generally accepted accounting principles and, if such is the normal practice of Tenant, shall be audited by an independent certified public accountant. Tenant hereby authorizes Landlord to obtain one or more credit reports on Tenant at any time, and shall execute such further authorizations as Landlord may reasonably require in order to obtain a credit report.

18.1Subordination. This Lease shall be subject and subordinate to all present and future ground or underlying leases of the Building or Project and to the lien of any mortgage, trust deed or other encumbrances now or hereafter in force against the Building or Project or any part thereof, if any, and to all renewals, extensions, modifications, consolidations and replacements thereof, and to all advances made or hereafter to be made upon the security of such mortgages or trust deeds (collectively, "Security Instruments"), unless the holders of such Security Instruments require in writing that this Lease be superior thereto; provided, however, at Tenant's sole cost and expense, Landlord shall use commercially reasonable efforts to provide Tenant a subordination non-disturbance and attornment agreement in commercially reasonable form provided by any future lienholder of such Security Instruments (the "Superior Holders"), which requires such Superior Holder to accept this lease, and not to disturb tenant’s possession, so long as a default has not occurred and is not then continuing (a "SNDA") executed by Landlord and the appropriate Superior Holder. This clause shall be self-operative and no further instrument of subordination need be required by any owner or holder of any Security Instrument; provided, however, that at Landlord's request, Tenant shall promptly execute any appropriate certificate or instrument that Landlord may request in confirmation thereof, and Tenant hereby constitutes and appoints Landlord as Tenant's attorney-in-fact to execute any such certificate or instrument for and on behalf of Tenant. In the event any proceedings are brought for the foreclosure of any such Security Instrument, Tenant covenants and agrees to attorn, without any deductions or set-offs whatsoever, to the lienholder or purchaser or any successors thereto upon any such foreclosure sale or deed in lieu thereof (or to the ground lessor), if so requested to do so by such purchaser or lienholder or ground lessor, and to recognize such purchaser or lienholder or ground lessor as the lessor under this Lease, provided such lienholder or purchaser or ground lessor shall agree to accept this Lease and not disturb Tenant's occupancy, so long as Tenant timely pays the rent and observes and performs the terms, covenants and conditions of this Lease to be observed and performed by Tenant. Landlord's interest herein may be assigned as security at any time to any lienholder. Tenant shall, within ten (10) business days of receipt of Landlord's written request, execute such further instruments or assurances as Landlord may reasonably deem necessary to evidence or confirm the subordination or superiority of this Lease to any such Security Instrument. Tenant waives the provisions of any current or future statute, rule or law which may give or purport to give Tenant any right or election to terminate or otherwise adversely affect this Lease and the obligations of the Tenant hereunder in the event of any foreclosure proceeding or sale. This Lease is further subject to and subordinate to all matters of record.

18.2Notice to Lienholder or Ground Lessor. Notwithstanding anything to the contrary in this Lease, upon receipt by Tenant of written notice from any holder of a Security Instrument in force against the Building or the Project or any part thereof which includes the Premises or any lessor under a ground lease or underlying lease of the Building or the Project, or from Landlord, which notice sets forth the address of such lienholder or ground lessor, no notice from Tenant to Landlord shall be effective unless and until a copy of the same is given to such lienholder or ground lessor at the appropriate address therefor (as specified in the above-described notice or at such other places as may be designated from time to time in a notice to Tenant), and the curing of any of Landlord's defaults by such lienholder or ground lessor within a reasonable period of time after such notice from Tenant (including a reasonable period of time to obtain possession of the Building or the Project, as the case may be, if such lienholder or ground lessor elects to do so) shall be treated as performance by Landlord.

During the Lease Term, Tenant shall have the right to use the number of unreserved parking passes and dedicated electric charging stations set forth in Section H of the Summary in the parking facility for the Project without payment of a separate parking fee or a parking charge (other than amounts included in Tenant's Share of Project Expenses). Notwithstanding anything set forth in this Article 19 to the contrary, Tenant shall be responsible for the full amount of any taxes imposed by any governmental authority in connection with the use of the parking facility by Tenant. Tenant shall not at any time park or permit the parking of its vehicles overnight or in any portion of the Project not designated by Landlord for non-exclusive parking. Tenant shall not have the exclusive right to park in any particular area of the parking facility for the Project, and if Landlord grants to any other tenant the exclusive right to park in any particular area of the parking facility for the Project, Tenant shall not park in such area; provided, however, this sentence shall not limit or reduce the amount of parking passes dedicated to Tenant and Tenant shall not be prohibited from temporarily parking customary passenger vehicles overnight in parking spaces exclusively reserved for Tenant. Tenant's continued right to use the parking passes allocated to it pursuant to this Lease is conditioned upon Tenant abiding by all rules and regulations which are prescribed from time to time for the orderly operation and use of the parking facility, including any sticker or other identification system established by Landlord, Tenant's cooperation in seeing that Tenant's employees and visitors also comply with such rules and regulations, and Tenant not being in default under this Lease beyond applicable notice and cure periods. Tenant's use of the Project parking facility shall be at Tenant's sole risk and Tenant acknowledges and agrees that Landlord shall have no liability whatsoever for damage to the vehicles of Tenant, its employees and/or visitors, or for other personal injury or property damage or theft relating to or connected with the parking rights granted herein or any of Tenant's, its employees' and/or visitors' use of the parking facilities. Landlord specifically reserves the right to change the size, configuration, design, layout and all other aspects of the Project parking facility at any time and Tenant acknowledges and agrees that Landlord may, without incurring any liability to Tenant and without any abatement of Rent under this Lease, from time to time, close-off or restrict access to the Project parking facility for purposes of permitting or facilitating any such construction, alteration or improvements, provided that, in connection therewith, Landlord shall perform such closures, alterations, additions or changes in a commercially reasonable manner and, in connection therewith, shall use commercially reasonable efforts to minimize any material interference with Tenant's use of and access to the parking facility for the Project.

20.1In General. Tenant shall not place on any portion of the Premises or the Building any sign, placard, lettering in or on windows, banner, displays or other advertising or communicative material which is visible from the exterior of the Building without the prior written approval of Landlord, which approval shall not be unreasonably withheld, conditioned or delayed. All such approved signs shall strictly conform to all Laws, Private Restrictions, and Landlord's commercially reasonable sign criteria then in effect and shall be installed at the expense of Tenant. Tenant shall maintain such signs in good condition and repair. On or prior to the expiration or earlier termination of the Lease Term, Tenant shall remove any and all signs installed by Tenant and to repair any damage to the Premises and Building caused by such removal and return any affected portion of the Premises and Building to the condition existing prior to the installation of such signs. If Tenant fails to complete the removal of any signs, then Rent shall continue to accrue under this Lease in accordance with Article 16, above, after the end of the Lease Term until such work shall be completed, and Landlord shall have the right, but not the obligation, to perform such work and to charge the cost thereof to Tenant.

20.2Tenant's Signage. Provided that Original Tenant or a Permitted Transferee Assignee then leases the entire Premises and occupies at least seventy-five percent (75%) of the Premises (for purposes of this Section 20.2, Tenant shall be deemed to occupy any space then occupied by any individual or entity pursuant to Sections 14.9 or 14.10, above), then Tenant shall have the right, at its sole cost and expense, to install (i) one or more signs on the exterior of the Building (provided Tenant's exterior signage on the Building may not exceed the exterior signage legally allowed on the Building), and (ii) a signage strip on any existing monument sign associated with the Building ("Tenant Signage"), the exact location or locations of which shall be mutually and reasonably agreed upon between Tenant and Landlord, and shall be subject to all applicable Laws and Landlord's prior approval, which approval shall not be unreasonably withheld, conditioned or delayed. The name set forth on the Tenant Signage shall in no event be an "Objectionable Name" (as that term is defined below). Except as otherwise set forth herein, Tenant shall have no obligation to pay a fee in connection with the Tenant Signage during the Lease Term or any renewal or extensions thereof. Tenant shall be responsible for all costs incurred in connection with the design, construction and installation of the Tenant Signage. Notwithstanding anything contained herein to the contrary, the graphics, materials, color, design, lettering, size, quality and specifications of the Tenant Signage shall be subject to the prior written approval of Landlord, which shall not be unreasonably withheld, conditioned or delayed and shall also comply with and be subject

to all applicable Laws, and all covenants, conditions or restrictions of record, including, but not limited to, all requirements of the City of San Jose (or other applicable governmental authorities); provided, however, that in no event shall the approval by the City of San Jose (or other applicable governmental authority) of Tenant Signage be deemed a condition precedent to the effectiveness of this Lease. Tenant shall be responsible, at its sole cost and expense, for the maintenance and repair and compliance with the requirements of the Tenant Signage. Upon the expiration or earlier termination of this Lease (or upon any earlier termination of Tenant's rights hereunder), Tenant shall be responsible, at Tenant's sole cost and expense, for the removal of all of the Tenant Signage and the repair of any damage resulting therefrom to the reasonable satisfaction of Landlord, including, without limitation, repairing and/or replacing any landscaping harmed by such removal. The rights contained in this Section 20.2 shall be exercised only by Original Tenant or a Permitted Transferee Assignee. The term "Objectionable Name" shall mean any name or logo which relates to an entity which is of a character or reputation, or is associated with a political orientation or faction, which is inconsistent with the quality of the Building, or which would otherwise reasonably offend a landlord of comparable buildings in the vicinity of the Building.

21.1Landlord's Right to Cure Default; Payments by Tenant. All covenants and agreements to be kept or performed by Tenant under this Lease shall be performed by Tenant at Tenant's sole cost and expense and without any reduction of Rent, except to the extent, if any, otherwise expressly provided herein. If Tenant shall fail to perform any obligation under this Lease, and such failure shall continue in excess of the time allowed under Section 13.1.2, above, unless a specific time period is otherwise stated in this Lease, Landlord may, but shall not be obligated to, make any such payment or perform any such act on Tenant's part without waiving its rights based upon any default of Tenant and without releasing Tenant from any obligations hereunder. If Tenant fails to comply with the terms of Section 7.1, above, including, without limitation, failure to carry out any required closure or decommissioning, or to promptly investigate, clean up, remove, restore, provide closure or otherwise remediate the Premises as required by Hazardous Materials Laws, Landlord may, but without obligation to do so, take any and all steps necessary to rectify the same and Tenant shall promptly reimburse Landlord, within ten (10) business days of demand, for all costs and expenses to Landlord of performing investigation, clean up, removal, restoration, closure and remediation work (the "Landlord Cure Right"). Except as may be specifically provided to the contrary in this Lease, Tenant shall pay to Landlord the following sums (which sums shall bear interest at the Agreed Interest Rate from the date accrued by Landlord until paid by Tenant, but in no case greater than the maximum amount of such interest permitted by law), upon delivery by Landlord to Tenant of statements therefor: (i) sums equal to expenditures reasonably made and obligations incurred by Landlord in connection with the remedying by Landlord of Tenant's defaults pursuant to the provisions of this Section 21.1; (ii) sums equal to all losses, costs, liabilities, damages and expenses referred to in Article 10 of this Lease; and (iii) sums equal to all expenditures made and obligations incurred by Landlord in collecting or attempting to collect the Rent or in enforcing or attempting to enforce any rights of Landlord under this Lease or pursuant to law, including, without limitation, all legal fees and other amounts so expended. Tenant's obligations under this Section 21.1 shall survive the expiration or sooner termination of this Lease.

21.2Landlord's Right to Enter. In addition to Landlord's right to enter the Premises pursuant to Section 6.2 of this Lease, Landlord and its agents reserve the right to enter the Premises at all reasonable times upon at least 24 hours' prior notice to Tenant (which notice, notwithstanding anything to the contrary contained in Section 21.5 of this Lease, may be oral, and which notice shall not be required in the case of an actual or apparent emergency) for the purpose of: (i) inspecting the same; (ii) posting notices of non-responsibility; (iii) supplying any service to be provided by Landlord to Tenant; (iv) showing the Premises to prospective purchasers or tenants (provided that Landlord shall only show to prospective tenants in the last twelve (12) months of the Lease Term), or current or prospective mortgagees, ground or underlying lessors or insurers; (v) performing services required of Landlord; (vi) performing Tenant's obligations when Tenant has failed to do so after written notice from Landlord; (vii) placing upon the Premises ordinary "for lease" signs or "for sale" signs (provided that Landlord shall only post “for lease” signs in the last twelve (12) months of the Lease Term); (viii) taking possession of the Premises due to any breach of this Lease in the manner provided herein; and (ix) responding to an emergency. Landlord shall have the right to use any and all means Landlord may deem necessary and proper to enter the Premises in an emergency. Any entry into the Premises obtained by Landlord in accordance with this Section 21.2 shall not be a forcible or unlawful entry into, or a detainer of, the Premises, or an eviction, actual or constructive, of Tenant from the Premises, and Tenant hereby waives any claims for damages or for any injuries or inconvenience to or interference with Tenant's business, lost profits, any loss of occupancy or quiet enjoyment of the Premises, and any other loss occasioned thereby.

21.3Notices. Any notice, demand, designation, approval or other communications (collectively, "Notices") given or required to be given by either party to the other hereunder or by law shall be in writing and shall be (A) sent by United States certified or registered mail, postage prepaid, return receipt requested ("Mail"),

(B) transmitted by telecopy, if such telecopy is promptly followed by a Notice sent by Mail, (C) delivered by a nationally recognized overnight courier, or (D) delivered personally to the addresses specified in Section Q or Section R of the Summary (as applicable). Any Notice will be deemed given (i) three (3) days after the date it is posted if sent by Mail, (ii) the date the telecopy is transmitted, (iii) the date the overnight courier delivery is made, or (iv) the date personal delivery is made. Any Notice given by an attorney on behalf of Landlord or by Landlord’s managing agent shall be considered as given by Landlord and shall be fully effective. Either party may change its address for Notices by giving Notice of the same in accordance with this Section 21.3.

21.4Covenant of Quiet Enjoyment. Landlord covenants that Tenant, on paying the Rent and on keeping, observing and performing all the other terms, covenants, conditions, provisions and agreements herein contained on the part of Tenant to be kept, observed and performed, shall, during the Lease Term, peaceably and quietly have, hold and enjoy the Premises subject to the terms, covenants, conditions, provisions and agreements hereof without interference by any persons lawfully claiming by or through Landlord.

21.5Terms; Captions. The words "Landlord" and "Tenant" as used herein shall include the plural as well as the singular. The necessary grammatical changes required to make the provisions hereof apply either to corporations or partnerships or individuals, men or women, as the case may require, shall in all cases be assumed as though in each case fully expressed. The terms "shall", "will" and "agree" are mandatory. The term "may" is permissive. The captions of Articles and Sections are for convenience only and shall not be deemed to limit, construe, affect or alter the meaning of such Articles and Sections.

21.6Binding Effect. Subject to all other provisions of this Lease, each of the covenants, conditions and provisions of this Lease shall extend to and shall, as the case may require, bind or inure to the benefit not only of Landlord and of Tenant, but also of their respective heirs, personal representatives, successors or assigns, provided this clause shall not permit any assignment by Tenant contrary to the provisions of Article 14 of this Lease.

21.7No Light, Air or View Rights. No rights to any view or to light or air over any property, whether belonging to Landlord or any other person, are granted to Tenant by this Lease. Under no circumstances whatsoever at any time during the Lease Term shall any temporary darkening of any windows of the Premises or any temporary obstruction of the light or view therefrom by reason of any repairs, improvements, maintenance or cleaning in or about the Project, or any diminution, impairment or obstruction (whether partial or total) of light, air or view by any structure which may be erected on any land comprising a part of, or located adjacent to or otherwise in the path of light, air or view to, the Project, in any way impose any liability upon Landlord or in any way reduce or diminish Tenant's obligations under this Lease.

21.8Modification of Lease. Should any current or prospective mortgagee or ground lessor for the Building or Project require a modification of this Lease, which modification will not cause an increased cost or expense to Tenant or in any other way materially and adversely change the rights and obligations of Tenant hereunder, then and in such event, Tenant agrees that this Lease may be so modified and agrees to execute whatever documents are reasonably required therefor and to deliver the same to Landlord within ten (10) days following a request therefor. At the request of Landlord or any mortgagee or ground lessor, Tenant agrees to execute a short form of Lease and deliver the same to Landlord within ten (10) days following the request therefor.

21.9Transfer of Landlord's Interest. Tenant acknowledges that Landlord has the right to transfer all or any portion of its interest in the Project or Building and in this Lease, and Tenant agrees that in the event of any such transfer, Landlord shall automatically be released from all liability under this Lease and Tenant agrees to look solely to such transferee for the performance of Landlord's obligations hereunder after the date of transfer and such transferee shall be deemed to have fully assumed and be liable for all obligations of this Lease to be performed by Landlord, including the return of any Security Deposit, and Tenant shall attorn to such transferee.

21.10Prohibition Against Recording. Except as provided in Section 21.8 of this Lease, neither this Lease, nor any memorandum, affidavit or other writing with respect thereto, shall be recorded by Tenant or by anyone acting through, under or on behalf of Tenant.

21.11Application of Payments. Landlord shall have the right to apply payments received from Tenant pursuant to this Lease, regardless of Tenant's designation of such payments, to satisfy any obligations of Tenant hereunder, in such order and amounts as Landlord, in its sole discretion, may elect.

21.12Time of Essence. Time is of the essence with respect to the performance of every provision of this Lease in which time of performance is a factor, including, without limitation, the giving of any Notice required to be

given under this Lease or by law, the time periods for giving any such Notice and the taking of any action with respect to any such Notice.

21.13Partial Invalidity. If any term, provision or condition contained in this Lease shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application of such term, provision or condition to persons or circumstances other than those with respect to which it is invalid or unenforceable, shall not be affected thereby, and each and every other term, provision and condition of this Lease shall be valid and enforceable to the fullest extent possible permitted by law.

21.14Right to Lease. Landlord reserves the absolute right to effect such other tenancies in the Project as Landlord in the exercise of its sole business judgment shall determine to best promote the interests of the Building or Project. Tenant does not rely on the fact, nor does Landlord represent, that any specific tenant or type or number of tenants shall, during the Lease Term, occupy any space in the Building or Project.

21.15Attorneys' Fees. In the event that either Landlord or Tenant should bring any action or legal proceeding for an alleged breach of any provision of this Lease, to recover any sum due under this Lease, for possession of the Premises, to terminate this Lease or otherwise to enforce, protect or establish any term or covenant of this Lease, the prevailing party shall be entitled to recover as a part of such action or proceeding, or in a separate action brought for that purpose, all costs and expenses incurred by such prevailing party, including, without limitation, reasonable attorneys' fees, court costs, and experts' fees as may be fixed by the court.

21.16Authority. If Tenant is a corporation, limited liability company, partnership or other entity, each individual executing this Lease on behalf of Tenant hereby represents and warrants that Tenant is a duly formed and existing entity qualified to do business in California, and that Tenant has full right and authority to execute and deliver this Lease and that each person signing on behalf of Tenant is authorized to do so. In such event, Tenant shall, within ten (10) days after execution of this Lease, deliver to Landlord satisfactory evidence of such authority and, if a corporation, upon demand by Landlord, also deliver to Landlord satisfactory evidence of (i) good standing in Tenant's state of incorporation, and (ii) qualification to do business in California.

21.17Governing Law; WAIVER OF TRIAL BY JURY. This Lease shall be construed and enforced in accordance with the laws of the State of California. IN ANY ACTION OR PROCEEDING ARISING HEREFROM, LANDLORD AND TENANT HEREBY CONSENT TO (I) THE JURISDICTION OF ANY COMPETENT COURT WITHIN THE STATE OF CALIFORNIA, (II) SERVICE OF PROCESS BY ANY MEANS AUTHORIZED BY CALIFORNIA LAW, AND (III) IN THE INTEREST OF SAVING TIME AND EXPENSE, TRIAL WITHOUT A JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER OF THE PARTIES HERETO AGAINST THE OTHER OR THEIR SUCCESSORS IN RESPECT OF ANY MATTER ARISING OUT OF OR IN CONNECTION WITH THIS LEASE, THE RELATIONSHIP OF LANDLORD AND TENANT, TENANT'S USE OR OCCUPANCY OF THE PREMISES, AND/OR ANY CLAIM FOR INJURY OR DAMAGE, OR ANY EMERGENCY OR STATUTORY REMEDY. IN THE EVENT LANDLORD COMMENCES ANY SUMMARY PROCEEDINGS OR ACTION FOR NONPAYMENT OF BASE MONTHLY RENT OR ADDITIONAL RENT, TENANT SHALL NOT INTERPOSE ANY COUNTERCLAIM OF ANY NATURE OR DESCRIPTION (UNLESS SUCH COUNTERCLAIM SHALL BE MANDATORY) IN ANY SUCH PROCEEDING OR ACTION, BUT SHALL BE RELEGATED TO AN INDEPENDENT ACTION AT LAW.

21.18Project or Building Name and Signage. Landlord shall have the right at any time to change the name of the Project or Building and to install, affix and maintain any and all signs on the exterior and on the interior of the Project or Building as Landlord may, in Landlord's sole discretion, desire; provided, however, that any Landlord signage shall not interfere with Tenant's then existing signage. Tenant shall not use the name of the Project or Building or use pictures or illustrations of the Project or Building in advertising or other publicity or for any purpose other than as the address of the business to be conducted by Tenant in the Premises, without the prior written consent of Landlord.

21.19Counterparts. This Lease may be executed in counterparts with the same effect as if both parties hereto had executed the same document. Both counterparts shall be construed together and shall constitute a single lease. Further, the parties hereto consent and agree that this Lease may be signed and/or transmitted by e-mail of a .pdf document or using electronic signature technology (e.g., via DocuSign or similar electronic signature technology), and that such signed electronic record shall be valid and as effective to bind the party so signing as a paper copy bearing such party's handwritten signature. The parties further consent and agree that (1) to the extent a party signs this Lease using electronic signature technology, by clicking "SIGN", such party is signing this Lease electronically, and (2) the electronic signatures appearing on this Lease shall be treated, for purposes of validity, enforceability and admissibility, the same as handwritten signatures.

21.20Intentionally Omitted.

21.21Building Renovations. It is specifically understood and agreed that Landlord has no obligation and has made no promises to alter, remodel, improve, renovate, repair or decorate the Premises, Building, or any part thereof and that no representations respecting the condition of the Premises or the Building have been made by Landlord to Tenant except as specifically set forth herein or in the Tenant Work Letter. However, Tenant hereby acknowledges that Landlord is currently renovating or may during the Lease Term renovate, improve, alter, or modify (collectively, the "Renovations") the Project, the Building and/or the Premises. Tenant hereby agrees that such Renovations shall in no way constitute a constructive eviction of Tenant nor entitle Tenant to any abatement of Rent. Landlord shall have no responsibility and shall not be liable to Tenant for any injury to or interference with Tenant's business arising from the Renovations, nor shall Tenant be entitled to any compensation or damages from Landlord for loss of the use of the whole or any part of the Premises or of Tenant's personal property or improvements resulting from the Renovations, or for any inconvenience or annoyance occasioned by such Renovations.

21.22Development of the Project.

21.22.1.Subdivision. Landlord reserves the right to further subdivide all or a portion of the Project. Tenant agrees to execute and deliver, within five (5) business days following demand by Landlord and in the form requested by Landlord, any additional documents needed to conform this Lease to the circumstances resulting from such subdivision.

21.22.2.The Other Improvements. If portions of the Project or property adjacent to the Project (collectively, the "Other Improvements") are owned by an entity other than Landlord, Landlord, at its option, may enter into an agreement with the owner or owners of any or all of the Other Improvements to provide (i) for reciprocal rights of access and/or use of the Project and the Other Improvements, (ii) for the common management, operation, maintenance, improvement and/or repair of all or any portion of the Project and the Other Improvements, (iii) for the allocation of a portion of the Project Expenses to the Other Improvements and the operating expenses and taxes for the Other Improvements to the Project, and (iv) for the use or improvement of the Other Improvements and/or the Project in connection with the improvement, construction, and/or excavation of the Other Improvements and/or the Project. Nothing contained herein shall be deemed or construed to limit or otherwise affect Landlord's right to convey all or any portion of the Project or any other of Landlord's rights described in this Lease.

21.22.3.Construction of Project and Other Improvements. Tenant acknowledges that portions of the Project and/or the Other Improvements may be under construction following Tenant's occupancy of the Premises, and that such construction may result in levels of noise, dust, odor, obstruction of access, etc. which are in excess of that present in a fully constructed project. Tenant hereby waives any and all rent offsets or claims of constructive eviction which may arise in connection with such construction. Notwithstanding the foregoing, Landlord shall use commercially reasonable efforts to minimize interference to Tenant’s use and occupancy of the Premises.

21.23No Discrimination. There shall be no discrimination against, or segregation of, any person or persons on account of sex, marital status, race, color, religion, creed, national origin or ancestry in the Transfer of the Premises, or any portion thereof, nor shall the Tenant itself, or any person claiming under or through it, establish or permit any such practice or practices of discrimination or segregation with reference to the selection, location, number, use or occupancy of tenants, lessees, subtenants, sublessees, or vendees of the Premises, or any portion thereof.

21.24Joint and Several. If there is more than one Tenant, the obligations imposed upon Tenant under this Lease shall be joint and several.

21.25Real Estate Brokers. Landlord and Tenant each represents and warrants to the other party that it has not authorized, retained or employed, or acted by implication to authorize, retain or employ, any real estate broker or salesman to act for it or on its behalf in connection with this Lease so as to cause the other party to be responsible for the payment of a brokerage commission, except for the Brokers identified in Section S of the Summary to this Lease (the "Brokers"). Landlord and Tenant shall each indemnify, defend and hold the other party harmless from and against any and all claims by any real estate broker or salesman (other than the Brokers) whom the indemnifying party authorized, retained or employed, or acted by implication to authorize, retain or employ, to act for the indemnifying party in connection with this Lease. Landlord agrees to pay Brokers a leasing commission in connection with this transaction in accordance with the provisions of a separate written agreement.

21.26Force Majeure. Any prevention, delay or stoppage due to strikes, lock-outs, inclement weather, labor disputes, inability to obtain labor, materials, fuels or reasonable substitutes therefor, governmental restrictions,

regulations, controls, action or inaction, civil commotion, fire or other acts of God, actual or threatened public health emergency (including, without limitation, epidemic, pandemic, famine, disease, plague, quarantine, and other significant public health risk) and other causes beyond the reasonable control of the party obligated to perform (except with respect to the obligations imposed with regard to Rent and other charges to be paid by Tenant pursuant to this Lease) (collectively, a "Force Majeure"), notwithstanding anything to the contrary contained in this Lease, shall excuse the performance of such party for a period equal to any such prevention, delay or stoppage and, therefore, if this Lease specifies a time period for performance of an obligation of either party, that time period shall be extended by the period of any delay in such party's performance caused by a Force Majeure.

21.27Entire Agreement. This Lease constitutes the entire agreement between the parties, and there are no binding agreements or representations between the parties except as expressed herein. Tenant acknowledges that neither Landlord nor Landlord's employees or agents have made any legally binding representation or warranty as to any matter except those expressly set forth herein, including any warranty as to (i) whether the Premises may be used for Tenant's intended use under existing applicable laws, (ii) the suitability of the Premises or the Project for the conduct of Tenant's business, (iii) the condition of any improvements, (iv) the amount of any item comprising Additional Rent or the amount of the Additional Rent in the aggregate, or that Landlord is furnishing the same services to other tenants, at all, on the same level or on the same basis. There are no oral agreements between Landlord and Tenant affecting this Lease, and this Lease supersedes and cancels any and all previous negotiations, arrangements, brochures, agreements and understandings, if any, between Landlord and Tenant or displayed by Landlord to Tenant with respect to the subject matter of this Lease. This instrument shall not be legally binding until it is executed by both Landlord and Tenant. No subsequent change or addition to this Lease shall be binding unless in writing and signed by Landlord and Tenant.

21.28Patriot Act; OFAC Compliance. As an inducement to Landlord to enter into this Lease, Tenant hereby represents and warrants that: (i) Tenant is not, nor is it owned or controlled directly or indirectly by, any person, group, entity or nation named on any list issued by the Office of Foreign Assets Control of the United States Department of the Treasury ("OFAC") pursuant to Executive Order 13224 or any similar list or any law, order, rule or regulation or any Executive Order of the President of the United States as a terrorist, "Specially Designated National and Blocked Person" or other banned or blocked person (any such person, group, entity or nation being hereinafter referred to as a "Prohibited Person"); (ii) Tenant is not (nor is it owned or controlled, directly or indirectly, by any person, group, entity or nation which is) acting directly or indirectly for or on behalf of any Prohibited Person; and (iii) neither Tenant (nor any person, group, entity or nation which owns or controls Tenant, directly or indirectly) has conducted or will conduct business or has engaged or will engage in any transaction or dealing with any Prohibited Person, including without limitation any assignment of this Lease or any subletting of all or any portion of the Premises or the making or receiving of any contribution of funds, goods or services to or for the benefit of a Prohibited Person. In connection with the foregoing, it is expressly understood and agreed that (x) any breach by Tenant of the foregoing representations and warranties shall be deemed a default by Tenant under Section 13.1.6 of this Lease and shall be covered by the indemnity provisions of Section 10.1 above, and (y) the representations and warranties contained in this subsection shall be continuing in nature and shall survive the expiration or earlier termination of this Lease.

21.29Intentionally Omitted.

21.30Utility Billing Information. In the event that the Tenant is permitted to contract directly for the provision of electricity, gas and/or water services to the Premises with the third-party provider thereof (all in Landlord's sole and absolute but reasonable discretion), Tenant shall within ten (10) business days following its receipt of written request from Landlord, provide Landlord with a copy of each requested invoice from the applicable utility provider. Tenant acknowledges that pursuant to California Public Resources Code Section 25402.10 and the regulations adopted pursuant thereto (collectively the "Energy Disclosure Requirements"), Landlord may be required to disclose information concerning Tenant’s energy usage at the Building to certain third parties, including, without limitation, prospective purchasers, lenders and tenants of the Building (the "Tenant Energy Use Disclosure"). Tenant hereby (A) consents to all such Tenant Energy Use Disclosures, and (B) acknowledges that Landlord shall not be required to notify Tenant of any Tenant Energy Use Disclosure. Further, Tenant hereby releases Landlord from any and all losses, costs, damages, expenses and liabilities relating to, arising out of and/or resulting from any Tenant Energy Use Disclosure. The terms of this Section 21.30 shall survive the expiration or earlier termination of this Lease.

21.31Governmental Incentives. Tenant may receive certain economic incentives (collectively, the "Incentives") from applicable governmental entities in connection with the location of Tenant's business within the City and State in which the Premises is located, provided that there shall be no material economic harm or unreasonable impact to Landlord by virtue of any such Incentives. Landlord, at Tenant's sole expense, will use commercially reasonable efforts to assist Tenant in acquiring the Incentives and will cooperate to the extent Tenant reasonably requests in order to complete any documentation in connection with Tenant's receipt of the benefit of the Incentives,

including supplying any necessary information, executing required forms, and other similar ministerial actions. In addition, if Landlord receives the benefit of any Incentives applied for and intended to be provided to Tenant, Landlord shall reasonably cooperate with Tenant, at Tenant's sole expense, to pass the benefit of such Incentives to Tenant.

22.1Delivery of Letter of Credit. Tenant shall deliver to Landlord, within ten (10) business days after Tenant's execution of this Lease, as protection for the full and faithful performance by Tenant of all of its obligations under this Lease and for all losses and damages Landlord may suffer (or which Landlord reasonably estimates that it may suffer) as a result of any breach or default by Tenant under this Lease, an unconditional, clean, irrevocable negotiable standby letter of credit (the "L-C") in the amount set forth in Section O of the Summary (the "L-C Amount"), in the form attached hereto as Exhibit F, payable in the City of San Francisco, California, running in favor of Landlord, drawn on a bank (the "Bank") reasonably approved by Landlord and at a minimum having a long term issuer credit rating from Standard and Poor’s Professional Rating Service of A or a rating from Moody’s Professional Rating Service of A-3 or better (the "Credit Rating Threshold"), and otherwise conforming in all respects to the requirements of this Article 22, including, without limitation, all of the requirements of Section 22.2 below, all as set forth more particularly hereinbelow. Tenant shall pay all expenses, points and/or fees incurred by Tenant in obtaining and maintaining the L/C. In the event of an assignment by Tenant of its interest in the Lease (and irrespective of whether Landlord's consent is required for such assignment), the acceptance of any replacement or substitute letter of credit by Landlord from the assignee shall be subject to Landlord's prior written approval, in Landlord's reasonable discretion, and the attorney's fees incurred by Landlord in connection with such determination shall be payable by Tenant to Landlord within thirty (30) days of billing.

22.2In General. The L-C shall be "callable" at sight, permit partial draws and multiple presentations and drawings, and be otherwise subject to the Uniform Customs and Practices for Documentary Credits (1993-Rev), International Chamber of Commerce Publication #500, or the International Standby Practices-ISP 98, International Chamber of Commerce Publication #590. Tenant further covenants and warrants as follows:

22.2.1.Landlord Right to Transfer. The L-C shall provide that Landlord, its successors and assigns, may, at any time and after notice to Tenant but without first obtaining Tenant's consent thereto, transfer (one or more times) all or any portion of its interest in and to the L-C to another party, person or entity, regardless of whether or not such transfer is separate from or as a part of the assignment by Landlord of its rights and interests in and to this Lease. In the event of a transfer of Landlord's interest in the Building, Landlord shall transfer the L-C, in whole or in part, to the transferee and thereupon Landlord shall, without any further agreement between the parties, be released by Tenant from all liability therefor, and it is agreed that the provisions hereof shall apply to every transfer or assignment of the whole or any portion of said L-C to a new landlord. In connection with any such transfer of the L-C by Landlord, Tenant shall, at Tenant's sole cost and expense, execute and submit to the Bank such applications, documents and instruments as may be necessary to effectuate such transfer, and Tenant shall be responsible for paying the Bank's transfer and processing fees in connection therewith.

22.2.2.No Assignment by Tenant. Tenant shall neither assign nor encumber the L-C or any part thereof. Neither Landlord nor its successors or assigns will be bound by any assignment, encumbrance, attempted assignment or attempted encumbrance by Tenant in violation of this Section.

22.2.3.Replenishment. If, as a result of any drawing by Landlord on the L-C pursuant to its rights set forth in Section 22.3 below, the amount of the L-C shall be less than the L-C Amount, Tenant shall, within five (5) business days thereafter, provide Landlord with (i) an amendment to the L-C restoring such L-C to the L-C Amount or (ii) additional L-Cs in an amount equal to the deficiency, which additional L-Cs shall comply with all of the provisions of this Article 22, and if Tenant fails to comply with the foregoing, notwithstanding anything to the contrary contained in Section 13.1 above, the same shall constitute an incurable default by Tenant under this Lease (without the need for any additional notice and/or cure period).

22.2.4.Renewal; Replacement. If the L-C expires earlier than the date (the "LC Expiration Date") that is ninety (90) days after the expiration of the Lease Term, Tenant shall deliver a new L-C or certificate of renewal or extension to Landlord at least sixty (60) days prior to the expiration of the L-C then held by Landlord, without any action whatsoever on the part of Landlord, which new L-C shall be irrevocable and automatically renewable through the LC Expiration Date upon the same terms as the expiring L-C or such other terms as may be acceptable to Landlord in its sole discretion. In furtherance of the foregoing, Landlord and Tenant agree that the L-C shall contain a so-called "evergreen provision," whereby the L-C will automatically be renewed unless at least sixty (60) days’ prior written

notice of non-renewal is provided by the issuer to Landlord; provided, however, that the final expiration date identified in the L-C, beyond which the L-C shall not automatically renew, shall not be earlier than the LC Expiration Date.

22.2.5.Bank’s Financial Condition. If, at any time during the Lease Term, the Bank’s long term credit rating is reduced below the Credit Rating Threshold, or the financial condition of the Bank changes in any other materially adverse way (either, a "Bank Credit Threat"), then Landlord shall have the right to require that Tenant obtain from a different issuer a substitute L-C that complies in all respects with the requirements of this Article 22, and Tenant’s failure to obtain such substitute L-C within ten (10) days following Landlord’s written demand therefor (with no other notice or cure or grace period being applicable thereto, notwithstanding anything in this Lease to the contrary) shall entitle Landlord, or Landlord’s then managing agent, to immediately draw upon the then existing L-C in whole or in part, without notice to Tenant, as more specifically described in Section 22.3 below. Tenant shall be responsible for the payment of any and all costs incurred with the review of any replacement L-C (including without limitation Landlord’s reasonable attorneys’ fees), which replacement is required pursuant to this Section or is otherwise requested by Tenant.

22.3Application of Letter of Credit. Tenant hereby acknowledges and agrees that Landlord is entering into this Lease in material reliance upon the ability of Landlord to draw upon the L-C as protection for the full and faithful performance by Tenant of all of its obligations under this Lease and for all losses and damages Landlord may suffer (or which Landlord reasonably estimates that it may suffer) as a result of any breach or default by Tenant under this Lease. Landlord, or its then managing agent, shall have the right to draw down an amount up to the face amount of the L-C if any of the following shall have occurred or be applicable: (A) such amount is due to Landlord under the terms and conditions of this Lease, or (B) Tenant has filed a voluntary petition under the U. S. Bankruptcy Code or any state bankruptcy code (collectively, "Bankruptcy Code"), or (C) an involuntary petition has been filed against Tenant under the Bankruptcy Code, or (D) the Bank has notified Landlord that the L-C will not be renewed or extended through the LC Expiration Date and Tenant has not provided a replacement L-C that satisfies the requirements of this Article 22 on or before the date that is thirty (30) days prior to the expiration thereof, or (E) a Bank Credit Threat or Receivership (as such term is defined in Section 22.6.1 below) has occurred and Tenant has failed to comply with the requirements of either Section 22.2.5 above or 22.6 below, as applicable. If Tenant shall breach any provision of this Lease or otherwise be in default hereunder, or if any of the foregoing events identified in Sections 22.3(B) through (E) shall have occurred, Landlord may, but without obligation to do so, and without notice to Tenant, draw upon the L-C, in part or in whole, and the proceeds may be applied by Landlord (i) to cure any breach or default of Tenant and/or to compensate Landlord for any and all damages of any kind or nature sustained or which Landlord reasonably estimates that it will sustain resulting from Tenant's breach or default, (ii) against any Rent payable by Tenant under this Lease that is not paid when due and/or (iii) to pay for all losses and damages that Landlord has suffered or that Landlord reasonably estimates that it will suffer as a result of any breach or default by Tenant under this Lease. The use, application or retention of the L-C, or any portion thereof, by Landlord shall not prevent Landlord from exercising any other right or remedy provided by this Lease or by any applicable law, it being intended that Landlord shall not first be required to proceed against the L-C, and shall not operate as a limitation on any recovery to which Landlord may otherwise be entitled. Tenant agrees not to interfere in any way with payment to Landlord of the proceeds of the L-C, either prior to or following a "draw" by Landlord of any portion of the L-C, regardless of whether any dispute exists between Tenant and Landlord as to Landlord's right to draw upon the L-C. No condition or term of this Lease shall be deemed to render the L-C conditional to justify the issuer of the L-C in failing to honor a drawing upon such L-C in a timely manner. Tenant agrees and acknowledges that (i) the L-C constitutes a separate and independent contract between Landlord and the Bank, (ii) Tenant is not a third party beneficiary of such contract, (iii) Tenant has no property interest whatsoever in the L-C or the proceeds thereof, and (iv) in the event Tenant becomes a debtor under any chapter of the Bankruptcy Code, neither Tenant, any trustee, nor Tenant's bankruptcy estate shall have any right to restrict or limit Landlord's claim and/or rights to the L-C and/or the proceeds thereof by application of Section 502(b)(6) of the U. S. Bankruptcy Code or otherwise.

22.4Letter of Credit not a Security Deposit. Landlord and Tenant acknowledge and agree that in no event or circumstance shall the L-C or any renewal thereof or any proceeds thereof be (i) deemed to be or treated as a "security deposit" within the meaning of California Civil Code Section 1950.7, (ii) subject to the terms of such Section 1950.7, or (iii) intended to serve as a "security deposit" within the meaning of such Section 1950.7. The parties hereto (A) recite that the L-C is not intended to serve as a security deposit and such Section 1950.7 and any and all other laws, rules and regulations applicable to security deposits in the commercial context ("Security Deposit Laws") shall have no applicability or relevancy thereto and (B) waive any and all rights, duties and obligations either party may now or, in the future, will have relating to or arising from the Security Deposit Laws.

22.5Proceeds of Draw. In the event Landlord draws down on the L-C pursuant to Section 22.3(D) or (E) above, the proceeds of the L-C may be held by Landlord and applied by Landlord against any Rent payable by Tenant under this Lease that is not paid when due and/or to pay for all losses and damages that Landlord has suffered or that

Landlord reasonably estimates that it will suffer as a result of any breach or default by Tenant under this Lease. Any unused proceeds shall constitute the property of Landlord and need not be segregated from Landlord's other assets. Tenant hereby (i) agrees that (A) Tenant has no property interest whatsoever in the proceeds from any such draw, and (B) such proceeds shall not be deemed to be or treated as a "security deposit" under the Security Deposit Law, and (ii) waives all rights, duties and obligations either party may now or, in the future, will have relating to or arising from the Security Deposit Laws. Landlord agrees that the amount of any proceeds of the L-C received by Landlord, and not (a) applied against any Rent payable by Tenant under this Lease that was not paid when due or (b) used to pay for any losses and/or damages suffered by Landlord (or reasonably estimated by Landlord that it will suffer) as a result of any breach or default by Tenant under this Lease (the "Unused L-C Proceeds"), shall be paid by Landlord to Tenant (x) upon receipt by Landlord of a replacement L-C in the full L-C Amount, which replacement L-C shall comply in all respects with the requirements of this Article 22, or (y) within thirty (30) days after the LC Expiration Date; provided, however, that if prior to the LC Expiration Date a voluntary petition is filed by Tenant, or an involuntary petition is filed against Tenant by any of Tenant's creditors, under the Bankruptcy Code, then Landlord shall not be obligated to make such payment in the amount of the Unused L-C Proceeds until either all preference issues relating to payments under this Lease have been resolved in such bankruptcy or reorganization case or such bankruptcy or reorganization case has been dismissed.

22.6Bank Placed Into Receivership.

22.6.1.Bank Placed Into Receivership. In the event the Bank is placed into receivership or conservatorship (any such event, a "Receivership") by the Federal Deposit Insurance Corporation or any successor or similar entity (the "FDIC"), then, effective as of the date such Receivership occurs, the L-C shall be deemed to not meet the requirements of this Article 22, and, within ten (10) days following Landlord's notice to Tenant of such Receivership (the "LC Replacement Notice"), Tenant shall (i) replace the L-C with a substitute L-C from a different issuer reasonably acceptable to Landlord and that complies in all respects with the requirements of this Article 22 or (ii), in the event Tenant demonstrates to Landlord that Tenant is reasonably unable to obtain a substitute L-C from a different issuer reasonably acceptable to Landlord and that complies in all respects with the requirements of this Article 22 within the foregoing ten (10) day period, deposit with Landlord cash in the L-C Amount (the "Interim Cash Deposit"); provided, however, that, in the case of the foregoing sub-clause (ii), Tenant shall, within sixty (60) days after the LC Replacement Notice, replace the L-C with a substitute L-C from a different issuer reasonably acceptable to Landlord and that complies in all respects with the requirements of this Article 22, and upon Landlord’s receipt and acceptance of such replacement L-C, Landlord shall return to Tenant the Interim Cash Deposit, with no obligation on the part of Landlord to pay any interest thereon. If Tenant fails to comply in any respect with the requirements of this Section 22.6.1, then, notwithstanding anything in this Lease to the contrary, Landlord shall have the right to (a) declare Tenant in default of this Lease for which there shall be no notice or grace or cure periods being applicable thereto other than the aforesaid ten (10) day and sixty (60) day periods, (b) if applicable, retain such Interim Cash Deposit until such time as such default is cured by Tenant, which retention shall not constitute a waiver of any right or remedy available to Landlord under the terms of this Lease or at law, and (c) pursue any and all remedies available to it under this Lease and at law, including, without limitation, if Tenant has failed to provide the Interim Cash Deposit, treating any Receivership as a Bank Credit Threat and exercising Landlord’s remedies herein, to the extent possible pursuant to then existing FDIC policy. Tenant shall be responsible for the payment of any and all costs incurred with the review of any replacement L-C (including without limitation Landlord’s reasonable attorneys’ fees), which replacement is required pursuant to this Section or is otherwise requested by Tenant.

22.6.2.Interim Cash Deposit. During any period that Landlord remains in possession of the Interim Cash Deposit (any such period, a "Deposit Period"), it is understood by the parties that such Interim Cash Deposit shall be held by Landlord as security for the full and faithful performance of Tenant’s covenants and obligations under this Lease. The Interim Cash Deposit shall not constitute an advance of any Rent, an advance payment of any other kind, nor a measure of Landlord’s damages in case of Tenant’s default. If, during any such Deposit Period, Tenant defaults with respect to any provisions of this Lease, including, but not limited to, the provisions relating to the payment of Rent, the removal of property and the repair of resultant damage, then Landlord may but shall not be required to, from time to time, without notice to Tenant and without waiving any other remedy available to Landlord, use the Interim Cash Deposit, or any portion of it, to the extent necessary to cure or remedy such default or failure or to compensate Landlord for all damages sustained by Landlord or which Landlord reasonably estimates that it will sustain resulting from Tenant’s default or failure to comply fully and timely with its obligations pursuant to this Lease. Tenant shall immediately pay to Landlord on demand any amount so applied in order to restore the Interim Cash Deposit to its original amount, and Tenant’s failure to immediately do so shall constitute a default under this Lease. In the event Landlord is in possession of the Interim Cash Deposit at the expiration or earlier termination of this Lease, and Tenant is in compliance with the covenants and obligations set forth in this Lease at the time of such expiration or termination, then Landlord shall return to Tenant the Interim Cash Deposit, less any amounts deducted by Landlord to reimburse Landlord for any sums to which Landlord is entitled under the terms of this Lease, within sixty (60) days following

both such expiration or termination and Tenant’s vacation and surrender of the Premises. Landlord’s obligations with respect to the Interim Cash Deposit are those of a debtor and not a trustee. Landlord shall not be required to maintain the Interim Cash Deposit separate and apart from Landlord’s general or other funds, and Landlord may commingle the Interim Cash Deposit with any of Landlord’s general or other funds. Tenant shall not at any time be entitled to interest on the Interim Cash Deposit. In the event of a transfer of Landlord's interest in the Building, Landlord shall transfer the Interim Cash Deposit, in whole or in part, to the transferee and thereupon Landlord shall, without any further agreement between the parties, be released by Tenant from all liability therefor, and it is agreed that the provisions hereof shall apply to every transfer or assignment of the whole or any portion of said Interim Cash Deposit to a new landlord. Tenant hereby waives the provisions of Section 1950.7 of the California Civil Code, or any successor statute.

22.7Reduction of L-C Amount. Provided that on or promptly following the "Reduction Date," as that term is defined below, Tenant tenders to Landlord (a) a copy of Tenant's most recent year-end financial statements prepared and certified by an independent certified public accountant or certified by an officer of Tenant, demonstrating that Tenant satisfies the "L-C Reduction Conditions," as that term is defined below, and (b) a new L-C conforming in all respects to the requirements of this Article 22 in the amount of the reduced L-C Amount as of such Reduction Date, or a certificate of amendment to the existing L-C, conforming in all respects to the requirements of this Article 21, in the amount of the reduced L-C Amount as of such Reduction Date, the L-C Amount shall be reduced pursuant to the following: Provided Tenant satisfies the L-C Reduction Conditions, the L-C Amount shall be reduced by an amount equal to thirty-three percent (33%) of the initial L-C Amount.

If Tenant is allowed to reduce the L-C Amount pursuant to the terms of this Section 22.7, then Landlord shall reasonably cooperate with Tenant in order to effectuate such reduction. For purposes of this Section 22 7, the "L-C Reduction Conditions" shall mean that (i) Tenant is not then in default under this Lease and has not been in monetary default under this Lease, beyond any applicable notice and cure period expressly set forth in this Lease, at any time during the Lease Term, and (ii) Tenant has achieved positive earnings before interest, taxes, depreciation and amortization ("EBITDA"), as determined in accordance with generally accepted accounting practices ("GAAP") plus stock compensation, for the trailing four (4) consecutive quarters. As used herein, the "Reduction Date" shall mean the date that Tenant satisfies the L-C Reduction Conditions.

IN WITNESS WHEREOF, Landlord and Tenant have executed this Lease with the intent to be legally bound thereby, to be effective as of the Effective Date.

If Tenant is a corporation incorporated in a state other than California, then Tenant shall deliver to Landlord evidence in a form reasonably acceptable to Landlord that the signatory(ies) is (are) authorized to execute this Lease.

This Exhibit is intended only to show the approximate location of the Premises in the Building, and is not meant to constitute an agreement, representation or warranty as to the construction of the Premises, the precise area thereof or the specific location of the Common Areas, or the elements thereof, or of the access ways to the Premises or the Project. The depiction of any interior windows, cubicles, modules, furniture and equipment in this Exhibit, if shown, is for illustrative purposes only, but does not mean that such items exist in the Premises or the Building, or that Landlord shall be obligated to provide, install or construct any such items. This Exhibit shall not be scaled; any measurements or distances shown should be taken as approximate. The inclusion of any elevators, stairways, electrical and mechanical closets, and other similar facilities for the benefit of occupants of the Building, if any, does not mean that such items are part of the Premises or the Building.

This Tenant Work Letter shall set forth the terms and conditions relating to the construction of the Premises. This Tenant Work Letter is essentially organized chronologically and addresses the issues of the construction of the Premises, in sequence, as such issues will arise during the actual construction of the Premises. All references in this Tenant Work Letter to Articles or Sections of "this Lease" shall mean the relevant portions of Articles 1 through 22 of the Lease to which this Tenant Work Letter is attached as Exhibit B, and all references in this Tenant Work Letter to Sections of "this Tenant Work Letter" shall mean the relevant portions of Sections 1 through 5 of this Tenant Work Letter.

Upon the Delivery Date, Landlord shall deliver the Premises to Tenant, and Tenant shall accept the Premises from Landlord, in its presently existing, "AS-IS" condition as of the date of this Lease.

2.1    Tenant Improvement Allowance. Tenant shall be entitled to a tenant improvement allowance (the "Tenant Improvement Allowance"), in the amount set forth in Section U of the Summary of Basic Lease Terms, for the costs relating to the design and construction of Tenant's improvements which are permanently affixed to the Premises (the "Tenant Improvements"). In no event shall Landlord be obligated to make disbursements pursuant to this Tenant Work Letter in a total amount which exceeds the Tenant Improvement Allowance. The Tenant Improvement Allowance shall expire two (2) years after the Delivery Date and any unused amount of the Tenant Improvement Allowance remaining on such date shall revert to Landlord. Any Tenant Improvements that require the use of Building risers, raceways, shafts and/or conduits, shall be subject to Landlord's reasonable rules, regulations, and restrictions, including the requirement that any cabling vender must be selected from a list provided by Landlord, and that the amount and location of any such cabling must be approved by Landlord, such approvals not to be unreasonably withheld, conditioned or delayed. All Tenant Improvements for which the Tenant Improvement Allowance has been made available shall be deemed Landlord's property under the terms of the Lease; provided, however, Landlord may, by written notice to Tenant prior to the end of the Lease Term, or given following any earlier termination of this Lease, require Tenant, at Tenant's expense, to remove any Tenant Improvements and to repair any damage to the Premises and Building caused by such removal and return the affected portion of the Premises to their condition existing prior to the installment of such Tenant Improvements; provided, however, that, notwithstanding the foregoing, upon written request by Tenant at the time of Tenant's request for Landlord's approval of the "Final Space Plan" and/or the "Final Working Drawings" (as those terms are defined in Section 3.2 and Section 3.3 of this Tenant Work Letter), Landlord shall notify Tenant in writing whether any item of the Tenant Improvements reflected in the Final Space Plan and/or the Final Working Drawings will be required to be removed pursuant to the terms of this Section 2.1.

2.2    Disbursement of the Tenant Improvement Allowance.

2.2.1    Tenant Improvement Allowance Items. Except as otherwise set forth in this Tenant Work Letter, the Tenant Improvement Allowance shall be disbursed by Landlord only for the following items and costs (collectively the "Tenant Improvement Allowance Items"):

2.2.1.1    Payment of the fees of the "Architect" and the "Engineers," as those terms are defined in Section 3.1 of this Tenant Work Letter, and Tenant’s construction manager fee, which fees shall, notwithstanding anything to the contrary contained in this Tenant Work Letter, not exceed an aggregate amount equal to $5.00 per rentable square foot of the Premises, and payment of the fees incurred by Landlord in connection with the preparation and review of the "Construction Drawings," as that term is defined in Section 3.1 of this Tenant Work Letter and in connection with the construction of the Tenant Improvements;

2.2.1.2    The payment of plan check, permit and license fees relating to construction of the Tenant Improvements;

2.2.1.3    The cost of construction of the Tenant Improvements, including, without limitation, testing and inspection costs, freight elevator usage, hoisting and trash removal costs, and contractors' fees and general conditions;

2.2.1.4    The cost of any changes in the base Building structure when such changes are required by the Construction Drawings (including if such changes are due to the fact that such work is prepared on an unoccupied basis), such cost to include all direct architectural and/or engineering fees and expenses incurred in connection therewith;

2.2.1.5    The cost of any changes to the Construction Drawings or Tenant Improvements required by all applicable building codes (the "Code");

2.2.1.6    The cost of connection of the Premises to the Building's energy management systems;

2.2.1.7    Sales and use taxes and Title 24 fees; and

2.2.1.8    All other actual and reasonable costs incurred by Landlord in connection with the construction of the Tenant Improvements.

2.2.2    Disbursement of Tenant Improvement Allowance. Subject to the provisions of this Tenant Work Letter, a check for the lesser of (a) the amount actually spent by Tenant for Tenant Improvement Allowance Items, and (b) the amount of the Tenant Improvement Allowance, shall be delivered by Landlord to Tenant within thirty (30) days following the completion of construction of the Premises, provided that (i) Tenant provide invoices marked paid, or other evidence of amounts expended by Tenant, (ii) Tenant delivers to Landlord properly executed mechanics lien releases in compliance with both California Civil Code Section 8134 and either Section 8136 or Section 8138, (iii) Landlord has determined that no substandard work exists which adversely affects the mechanical, electrical, plumbing, heating, ventilating and air conditioning, life-safety or other systems of the Building, the curtain wall of the Building, the structure or exterior appearance of the Building, and Landlord does not dispute any request for payment based on non-compliance of any work with the "Approved Working Drawings," as that term is defined in Section 3.4 below, and (iv) Architect delivers to Landlord a certificate, in a form reasonably acceptable to Landlord, certifying that the construction of the Tenant Improvements in the Premises has been substantially completed.

2.2.3    Other Terms. Landlord shall only be obligated to make disbursements from the Tenant Improvement Allowance to the extent costs are incurred by Tenant for Tenant Improvement Allowance Items. All Tenant Improvement Allowance Items for which the Tenant Improvement Allowance has been made available shall be deemed Landlord's property under the terms of this Lease.

2.3    Standard Tenant Improvement Package. The quality of Tenant Improvements shall be equal to or of greater quality than the quality of Building standard components customary in buildings in comparable properties located in San Jose, California, provided that the Tenant Improvements shall comply with any specifications reasonably designated by Landlord and communicated to Tenant prior to the design and construction of the Tenant Improvements.

2.4    Preliminary Space Plan Allowance. In addition to the Tenant Improvement Allowance, Landlord shall pay an amount up to Fifteen Cents ($0.15) per rentable square foot of the Premises (the "Space Plan Allowance") for the preparation by Tenant's Architect of a preliminary space plan for the Premises (the "Space Plan"). In no event shall Landlord make disbursements from the Space Plan Allowance for costs which are either (i) unrelated to the Space Plan, or (ii) with respect to the Space Plan, in a total amount which exceeds the Space Plan Allowance.

The Over-Allowance Amount shall be disbursed by Landlord prior to the disbursement of any of the then remaining portion of the Tenant Improvement Allowance, and such disbursement shall be pursuant to the same procedure as the Tenant Improvement Allowance. In the event that, after the Final Costs have been delivered by Tenant to Landlord, the costs relating to the design and construction of the Tenant Improvements shall change, any additional costs necessary to such design and construction in excess of the Final Costs, shall be paid by Tenant to Landlord immediately as an addition to the Over-Allowance Amount or at Landlord's option, Tenant shall make payments for such additional costs out of its own funds, but Tenant shall continue to provide Landlord with the documents described in Sections 2.2.2.1 (i), (ii), (iii) and (iv) of this Tenant Work Letter, above, for Landlord's approval, prior to Tenant paying such costs. If after the completion of the Tenant Improvements, it is

The foregoing indemnity shall not apply to claims caused by the gross negligence or willful misconduct of Landlord or its or their members, partners, shareholders, officers, directors, agents, employees and/or contractors, or the failure of Landlord to disburse the Tenant Improvement Allowance as and when required hereunder.

The HMIS will include much of the information listed in Section 2-2. Neither the landlord nor the landlord’s property management company expressly warrants that the inventory provided in Section 2-2 will necessarily meet the applicable California Fire Code fire control area limits for building occupancy, especially in shared tenant occupancy situations. It is the responsibility of the tenant to ensure that a facility and site can legally handle the intended operations and hazardous materials desired/ needed for its operations, but the landlord is happy to assist in this determination when possible.    

I am familiar with the real property described in this questionnaire. By signing below, I represent and warrant that the answers to the above questions are complete and accurate to the best of my knowledge. I also understand that Lessor will rely on the completeness and accuracy of my answers in assessing any environmental liability risks associated with the property.

1.    Option Right. Landlord hereby grants to the originally named Tenant herein (the "Original Tenant") and any Permitted Transferee Assignee two (2) option(s) to extend the Lease Term each for a period of five (5) years (each an "Option Term" and, together, the "Option Terms"). Such option shall be irrevocably exercised only by written notice delivered by Tenant to Landlord no earlier than fifteen (15) months and no later than twelve (12) months prior to the expiration of the Lease Term (or initial Option Term, as applicable), provided that the following conditions (the "Option Conditions") are satisfied: (i) as of the date of delivery of such notice, Tenant is not then in default under this Lease; (ii) as of the end of the Lease Term (or initial Option Term, as applicable), Tenant is not then in default under this Lease; (iii) Tenant has not previously been in default under this Lease beyond any applicable notice and cure period; and (iv) the Lease then remains in full force and effect and Original Tenant occupies the entire Premises at the time the option to extend is exercised and as of the commencement of the Option Term. Landlord may, at Landlord's option, exercised in Landlord's sole and absolute discretion, waive any of the Option Conditions in which case the option, if otherwise properly exercised by Tenant, shall remain in full force and effect. Upon the proper exercise of such option to extend, and provided that Tenant satisfies all of the Option Conditions (except those, if any, which are waived by Landlord), the Lease Term, as it applies to the Premises, shall be extended for a period of five (5) years. The rights contained in this Section 1 shall be personal to Original Tenant and may be exercised by Original Tenant only (and not by any assignee, sublessee or other Transferee, of Tenant's interest in this Lease).

2.    Option Rent. The annual Rent payable by Tenant during the Option Term (the "Option Rent") shall be equal to the Fair Market Rent Rate, as that term is defined below, for the Premises as of the commencement date of the Option Term. The "Fair Market Rent Rate," as used in this Lease, shall be equal to the annual rental rate per rentable square foot projected as of the start of the Option Term (including additional rent and considering any "base year" or "expense stop" applicable thereto), including all escalations, at which tenants (pursuant to recently consummated leases projected to the first day of the Option Term), are leasing non-sublease, non-encumbered, non-equity space comparable in size, location and quality to the Premises, for a term of five (5) years, in an arm's length transaction, which comparable space is located in Comparable Buildings, as that term is defined in this Section 2, below (transactions satisfying the foregoing criteria shall be known as the "Comparable Transactions"), taking into consideration the following concessions (the "Concessions"): (a) rental abatement concessions, if any, being granted such tenants in connection with such comparable space; (b) tenant improvements or allowances provided or to be provided for such comparable space, and taking into account the value, if any, of the existing improvements in the subject space, such value to be based upon the age, condition, design, quality of finishes and layout of the improvements; and (c) other reasonable monetary concessions being granted such tenants in connection with such comparable space; provided, however, that in calculating the Fair Market Rent Rate, no consideration shall be given to any period of rental abatement, if any, granted to tenants in Comparable Transactions in connection with the design, permitting and construction of tenant improvements in such comparable spaces. The Fair Market Rent Rate shall additionally include a determination as to whether, and if so to what extent, Tenant must provide Landlord with financial security, such as a letter of credit or guaranty, for Tenant's Rent obligations in connection with Tenant's lease of the Premises during the Option Term. Such determination shall be made by reviewing the extent of financial security then generally being imposed in Comparable Transactions from tenants of comparable financial condition and credit history to the then existing financial condition and credit history of Tenant (with appropriate adjustments to account for differences in the then-existing financial condition of Tenant and such other tenants). The Concessions (A) shall be reflected in the effective rental rate (which effective rental rate shall take into consideration the total dollar value of such Concessions as amortized on a straight-line basis over the applicable term of the Comparable Transaction (in which case such Concessions evidenced in the effective rental rate shall not be granted to Tenant)) payable by Tenant, or (B) at Landlord’s election, all such Concessions shall be granted to Tenant in kind. For purposes of this Lease, the term "Comparable Buildings" shall mean the Building and those certain other comparable institutionally-owned research and development and/or life science buildings of similar size, age, location, quality of appearance and services to the Building, and located in the San Jose, California area.

3    Determination of Option Rent. In the event Tenant timely and appropriately exercises its option to extend the Lease Term pursuant to Section 1, above, Landlord shall deliver written notice (the "Landlord Response Notice") to Tenant on or before the date which is thirty (30) days after Landlord's receipt of the Exercise Notice of Landlord's determination of the Option Rent. Within ten (10) days following its receipt of the Landlord Response Notice, Tenant shall notify Landlord in writing whether it accepts or objects to the Option Rent set forth in Landlord's Response Notice. In the event that Tenant in good faith objects to Landlord's determination of the Option Rent, then Landlord and Tenant shall meet and attempt to agree upon the Option Rent using their best good-faith efforts. If Landlord and Tenant fail to reach agreement on or before the date that is ninety (90) days prior to the expiration of the initial Lease Term (or initial Option Term, as applicable) (the "Outside Agreement Date"), then the Option Rent

shall be determined by arbitration pursuant to the terms of this Section 3. Each party shall make a separate determination of the Option Rent, within five (5) days following the Outside Agreement Date, and such determinations shall be submitted to arbitration in accordance with Section 3.1 through Section 3.4, below. The determination of the arbitrators shall be made by taking into consideration all Comparable Transactions as calculated by calculating the net rent, which net rent shall then be adjusted on an effective basis, which net effective rent shall then be present valued and reduced by all upfront concessions and, thereafter, shall be future valued into an average annual constant rental rate figure (collectively, the "Constant Rate Equivalent Approach").

3.1    Landlord and Tenant shall each appoint one arbitrator who shall by profession be a MAI appraiser, real estate broker, or real estate lawyer who shall have been active over the five (5) year period ending on the date of such appointment in the appraising and/or leasing of institutionally-owned properties in the vicinity of the Building. The determination of the arbitrators shall be limited solely to the issue area of whether Landlord's or Tenant's submitted Option Rent is the closest to the actual Option Rent as determined by the arbitrators, taking into account the requirements of Section 2, above. Each such arbitrator shall be appointed within fifteen (15) days after the Outside Agreement Date. Landlord and Tenant may consult with their selected arbitrators prior to appointment and may select an arbitrator who is favorable to their respective positions (including an arbitrator who has previously represented Landlord and/or Tenant, as applicable). The arbitrators so selected by Landlord and Tenant shall be deemed "Advocate Arbitrators."

3.2    The two Advocate Arbitrators so appointed shall be specifically required pursuant to an engagement letter within ten (10) days of the appointment of the last appointed Advocate Arbitrator to agree upon and appoint a third arbitrator ("Neutral Arbitrator") who shall be qualified under the same criteria set forth hereinabove for qualification of the two Advocate Arbitrators except that (i) neither the Landlord or Tenant or either parties' Advocate Arbitrator may, directly, or indirectly, consult with the Neutral Arbitrator prior or subsequent to his or her appearance, and (ii) the Neutral Arbitrator cannot be someone who has represented Landlord and/or Tenant during the five (5) year period prior to such appointment. The Neutral Arbitrator shall be retained via an engagement letter jointly prepared by Landlord's counsel and Tenant's counsel.

3.3    Within ten (10) days following the appointment of the Arbitrator, Landlord and Tenant shall enter into an arbitration agreement (the "Arbitration Agreement") which shall set forth the following:

3.3.1    Each of Landlord's and Tenant's best and final and binding determination of the Option Rent exchanged by the parties pursuant to Section 3, above;

3.3.2    An agreement to be signed by the Neutral Arbitrator, the form of which agreement shall be attached as an exhibit to the Arbitration Agreement, whereby the Neutral Arbitrator shall agree to undertake the arbitration and render a decision in accordance with the terms of this Lease, as modified by the Arbitration Agreement, and shall require the Neutral Arbitrator to demonstrate to the reasonable satisfaction of the parties that the Neutral Arbitrator has no conflicts of interest with either Landlord or Tenant;

3.3.3    Instructions to be followed by the Neutral Arbitrator when conducting such arbitration;

3.3.4    That Landlord and Tenant shall each have the right to submit to the Neutral Arbitrator (with a copy to the other party), on or before the date that occurs fifteen (15) days following the appointment of the Neutral Arbitrator, an advocate statement (and any other information such party deems relevant) prepared by or on behalf of Landlord or Tenant, as the case may be, in support of Landlord's or Tenant's respective determination of Option Rent (the "Briefs");

3.3.5    That within five (5) business days following the exchange of Briefs, Landlord and Tenant shall each have the right to provide the Neutral Arbitrator (with a copy to the other party) with a written rebuttal to the other party's Brief (the "Rebuttals"); provided, however, such First Rebuttals shall be limited to the facts and arguments raised in the other party's Brief and shall identify clearly which argument or fact of the other party's Brief is intended to be rebutted;

3.3.6    The date, time and location of the arbitration, which shall be mutually and reasonably agreed upon by Landlord and Tenant, taking into consideration the schedules of the Neutral Arbitrator, the Advocate Arbitrators, Landlord and Tenant, and each party's applicable consultants, which date shall in any event be within forty-five (45) days following the appointment of the Neutral Arbitrator;

3.3.7    That no discovery shall take place in connection with the arbitration, other than to verify the factual information that is presented by Landlord or Tenant;

3.3.8    That the Neutral Arbitrator shall not be allowed to undertake an independent investigation or consider any factual information other than presented by Landlord or Tenant, except that the Neutral Arbitrator shall be permitted to visit the Project and the buildings containing the Comparable Transactions;

3.3.9    The specific persons that shall be allowed to attend the arbitration;

3.10    Tenant shall have the right to present oral arguments to the Neutral Arbitrator at the arbitration for a period of time not to exceed two (2) hours ("Tenant's Initial Statement");

3.3.11    Following Tenant's Initial Statement, Landlord shall have the right to present oral arguments to the Neutral Arbitrator at the arbitration for a period of time not to exceed two (2) hours ("Landlord's Initial Statement");

3.3.12    Following Landlord's Initial Statement, Tenant shall have one (1) additional hour to present additional arguments and/or to rebut the arguments of Landlord ("Tenant's Rebuttal Statement");

3.3.13    Following Tenant's Rebuttal Statement, Landlord shall have one (1) additional hour to present additional arguments and/or to rebut the arguments of Tenant;

3.3.14    That, not later than ten (10) days after the date of the arbitration, the Neutral Arbitrator shall render a decision (the "Ruling") indicating whether Landlord's or Tenant's submitted Option Rent is closer to the Option Rent;

3.3.15    That following notification of the Ruling, Landlord's or Tenant's submitted Option Rent determination, whichever is selected by the Neutral Arbitrator as being closer to the Option Rent shall become the then applicable Option Rent;

3.3.16    That the decision of the Neutral Arbitrator shall be binding on Landlord and Tenant; and

3.3.17    If a date by which an event described in Section 3.3, above, is to occur falls on a weekend or a holiday, the date shall be deemed to be the next business day.

3.4    In the event that the Option Rent shall not have been determined pursuant to the terms hereof prior to the commencement of the Option Term, Tenant shall be required to pay the average of the Option Rent submitted by Landlord to the arbitration and the Option Rent submitted by Tenant to the arbitration, and upon the final determination of the Option Rent, the payments made by Tenant shall be reconciled with the actual amounts due, and the appropriate party shall make any corresponding payment to the other party.
