If, during any portion of the Base Year or any Expense Year, the Building is not 100% occupied (or a service provided by Landlord to tenants of the Building generally is not provided by Landlord to a tenant that provides such service itself, or any tenant of the Building is entitled to free rent, rent abatement or the like), Expenses for such year shall be determined as if the Building bad been 100% occupied (and all services provided by Landlord to tenants of the Building generally had been provided by Landlord to all tenants, and no tenant of the Building had been entitled to free rent, rent abatement or the like) during such portion of such year. If a tenant of the Building reimburses Landlord on a separately measured

basis, and not through payment of operating costs or expenses, for a service that is provided by Landlord to tenants of the Building generally, then, for purposes of the preceding sentence, such service shall be deemed to be provided to such tenant by such tenant itself and not by Landlord. If insurance, security or utility costs for any Expense Year are less than insurance, security or utility costs, respectively, for the Base Year, then, for purposes of determining Expenses for such Expense Year, such costs for such Expense Year shall be deemed to be increased so as to be equal to such corresponding costs for the Base Year.

If Landlord does not carry earthquake, terrorism or another type of insurance for the Building during the Base Year but carries such type of insurance for the Building during any Expense Year, then, for purposes of determining the Expense Excess for such Expense Year, Expenses for the Base Year shall be deemed to be increased by the amount of the premium Landlord would have Incurred for such type of insurance during the Base Year if Landlord had maintained such type of insurance for the same period of time during the Base Year as such insurance is maintained by Landlord during such Expense Year. If, in any Expense Year, Landlord provides a new type of service (as opposed to an expansion in scope of a service or a change in a type of service) that (i) is not required by Law, (ii) is not than generally provided by the landlords of Comparable Buildings (defined in Section 25.10), (iii) is not then being provided in order to enhance the health, safety or security of the tenants, occupants and users of the Building as a result of circumstances that Landlord reasonably believes are specific to the Building and do not exist at Comparable Buildings, and (iv) was not provided by Landlord during the Base Year, then, for purposes of determining the Expense Excess for such Expense Year, Expenses for the Base Year shall be deemed to be increased by the amount that Landlord would have incurred for such service during the Base Year if Landlord had provided such service for the same period of time during the Base Year as such service is provided by Landlord during such Expense Year.

4.2.3 “Taxes” means all federal, state, county or local governmental or municipal taxes, fees, charges, assessments, levies, licenses or other impositions, whether general, special, ordinary or extraordinary, that are paid or accrued during the Base Year or any Expense Year (without regard to any different fiscal year used by such governmental or municipal authority) because of or in connection with the ownership, leasing or operation of the Property. Taxes shall include (a) real estate taxes; (b) general and special assessments; (c) transit taxes (including, without limitation, any taxes imposed by any governmental or quasi-governmental agency in connection with the Parking Facility); (d) leasehold taxes; (e) personal property taxes imposed upon the fixtures, machinery, equipment, apparatus, systems, appurtenances, furniture and other personal property used in connection with the Property; (f) any tax on the rent, right to rent or other income from any portion of the Property or as against the business of leasing any portion of the Property; (g) any assessment, tax, fee, levy or charge imposed by any governmental agency, or by any non-governmental entity pursuant to any private cost-sharing agreement, in order to fund the provision or enhancement of any fire-protection, street, sidewalk- or road-maintenance, refuse-removal or other service that is (or, before the enactment of Proposition 13, was) normally provided by governmental agencies to property owners or occupants without charge (other than through real property taxes); and (b) any assessment, tax, fee, levy or charge allocable or measured by the area of the Premises or by the Rent payable hereunder, including any business, gross income, gross receipts, sales or excise tax with respect to the receipt of such Rent. Any coats and expenses (including reasonable attorneys’ and consultants’ fees) incurred in attempting to protest, reduce or minimize Taxes shall be included in Taxes for the year in which they are incurred. Notwithstanding any contrary provision hereof, Taxes shall be determined without regard to any “green building” credit and shall exclude (i) all excess profits taxes, franchise taxes, gift taxes, capital stock taxes, inheritance and

succession taxes, estate taxes, federal and state income taxes, and other taxes to the extent applicable to Landlord’s general or net income (as opposed to rents, receipts or income attributable to operations at the Property), (ii) any Expenses, and (iii) any items required to be paid by Tenant under Section 4.5.

4.3 Allocation. Landlord, in its reasonable discretion, shall equitably allocate Expenses among office, retail or other portions or occupants of the Property. If Landlord incurs Expanses or Taxes for the Property together with another property, Landlord, in its reasonable discretion, shall equitably allocate such shared amounts between the Property and such other property.

4.4 Calculation and ▇▇▇▇▇▇ of Expense Excess and Tex Excess.

4.4.1 Statement of Actual Expenses and Taxes; Payment by Tenant. Landlord shall give to Tenant, after the end of each Expense Year, a statement (the “Statement”) setting forth the actual Expenses, Taxes, Expense Excess and Tax Excess for such Expense Year. If the amount paid by Tenant for such Expense Year pursuant to Section 4.4.2 is less or more than the sum of Tenant’s Share of the actual Expense Excess plus Tenant’s Share of the actual Tax Excess (as such amounts are set forth in such Statement), Tenant shall pay Landlord the amount of such underpayment, or receive a credit in the amount of such overpayment, with or against the Rent then or next due hereunder; provided, however, that if this Lease has expired or terminated and Tenant has vacated the Premises, Tenant shall pay Landlord the amount of such underpayment, or Landlord shall pay Tenant the amount of such overpayment (less any Rent due), within 30 days after delivery of such Statement. Landlord shall use reasonable efforts to deliver the Statement on or before June 1 of the calendar year immediately following the Expense Year to which it applies. Any failure of Landlord to timely deliver the Statement for any Expense Year shall not diminish either party’s rights under this Section 4.

4.4.2 Statement of Estimated Expenses and Taxes. Landlord shall give to Tenant, for each Expense Year, a statement (the “Estimate Statement”) setting forth Landlord’s reasonable estimates of the Expenses, Taxes, Expense Excess (the “Estimated Expense Excess”) and Tax Excess (the “Estimated Tax Excess”) for such Expense Year. Upon receiving an Estimate Statement, Tenant shall pay, with its next installment of Base Rent, an amount equal to the excess of (a) the amount obtained by multiplying (i) the sum of Tenant’s Share of the Estimated Expense Excess plus Tenant’s Share of the Estimated Tax Excess (as such amounts are set forth in such Estimate Statement), by (ii) a fraction, the numerator of which is the number of months that have elapsed in the applicable Expense Year (including the month of such payment) and the denominator of which is 12, over (b) any amount previously paid by Tenant for such Expense Year pursuant to this Section 4.4.2. Until Landlord delivers a new Estimate Statement, Tenant shall pay monthly, with the monthly Base Rent installments, an amount equal to one-twelfth (1/12) of the sum of Tenant’s Share of the Estimated Expense Excess plus Tenant’s Share of the Estimated Tax Excess, as and amounts are set forth in the previous Estimate Statement. Landlord shall use reasonable efforts to deliver an Estimate Statement for each Expense Year on or before January 1 of such Expense Year. Any failure of Landlord to timely deliver any Estimate Statement shall not diminish Landlord’s rights to receive payments and revise any previous Estimate Statement under this Section 4.

4.4.3 Retroactive Adjustment of Taxes. Notwithstanding any contrary provision hereof, if, after Landlord’s delivery of any Statement, an increase or decrease in Taxes occurs for the applicable Expense Year or for the Base Year (whether by reason of reassessment, error, or otherwise), Taxes for such Expense Year or the Base Year, as the case may be, and the Tax Excess for such Expense Year shall be retroactively adjusted. If, as a result of such adjustment, it is determined that Tenant has under- or overpaid Tenant’s Share of such Tax Excess, Tenant shall pay Landlord the amount of such underpayment, or receive a credit in the amount of such overpayment, with or against the Rent then or next due hereunder; provided, however, that if this Lease has expired or terminated and Tenant has vacated the Premises, Tenant shall pay Landlord the amount of such underpayment, or Landlord shall pay Tenant the amount of such overpayment (less any Rent due), within 30 days after such adjustment is made.

4.5 Charges for Which Tenant Is Directly Responsible. Tenant shall pay, 10 days before delinquency, any taxes levied against Tenant’s equipment, furniture, fixtures and other personal property located in or about the Premises. If any such taxes are levied against Landlord or its property (or if the assessed value of Landlord’s property is increased by the inclusion therein of a value placed upon such equipment, furniture, fixtures or other personal property of Tenant), Landlord may pay such taxes (or such increased assessment) regardless of their (or its) validity, in which event Tenant, upon demand, shall repay to Landlord the amount so paid. If the Leasehold Improvements (defined in Section 7.1) 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, the Taxes levied against Landlord or the Property by reason of such excess assessed valuation shall be deemed taxes levied against Tenant’s personal property for purposes of this Section 4.5. Notwithstanding any contrary provision hereof; Tenant shall pay, 10 days before delinquency, (i) any rent tax, sales tax. service tax, transfer tax or value added tax, or any other tax respecting the rent or services described herein or otherwise respecting this transaction or this Lease; and (ii) any taxes assessed upon the possession, leasing, operation, management, maintenance, alteration, repair, use or occupancy by Tenant of any portion of the Property.

4.6 Books and Records. Within 60 days after receiving any Statement (the “Review Notice Period”), Tenant may give Landlord notice (“Review Notice”) stating that Tenant elects to review Landlord’s calculation of the Expense Excess and/or Tax Excess for the Expense Year to which such Statement applies and identifying with reasonable specificity the records of Landlord reasonably relating to such matters that Tenant desires to review. Within a reasonable time after receiving a timely Review Notice (and, at Landlord’s option, an executed confidentiality agreement as described below), Landlord shall deliver to Tenant, or make available for inspection at a location reasonably designated by Landlord, copies of such records. Within 60 days after such records are made available to Tenant (the “Objection Period”), Tenant may deliver to Landlord notice (an ‘Objection Notice”) stating with reasonable specificity any objections to the Statement in which event landlord and Tenant shall work together in good faith to resolve Tenant’s objections. Tenant may not deliver more than one Review Notice or more than one Objection Notice with respect to any Expense Year. If Tenant fails to give Landlord a Review Notice before the expiration of the Review Notice Period or fails to give Landlord an Objection Notice before the expiration of the Objection Period, Tenant shall be deemed to have approved the Statement. Notwithstanding any contrary provision hereof, Landlord shall not be required to deliver or make available to Tenant records relating to the Base Year, and Tenant may not object to Expenses or Taxes for the Base Year, other than in connection with the first review for an Expense Year performed by Tenant pursuant to this Section 4.6. If Tenant retains an agent to review Landlord’s records, the agent must be with a CPA firm licensed to do business in the State of California and its fees shall not be contingent, in whole or in part, upon the outcome of the review. Tenant shall be responsible for all costs of such review; provided, however, that if Landlord and Tenant determine that the sum of Expenses and Taxes for the Expense Year in question was overstated by more than 5%, Landlord, within 30 days after receiving paid invoices therefor from Tenant, shall reimburse Tenant for the reasonable amounts paid by Tenant to third parties in connection with such review (not to exceed $5,000.00). The records and any related information obtained from Landlord shall be treated as confidential, and as applicable only to the Premises, by Tenant, its auditors, consultants, and any other parties reviewing the same on behalf of Tenant (collectively, “Tenant’s Auditors”). Before making any records available for review, Landlord may require Tenant and Tenant’s Auditors to execute a reasonable confidentiality agreement, in which event Tenant shall cause the same to be executed and delivered to Landlord within 30 days after receiving it from Landlord, and if Tenant fails to do so, the Objection Period shall be reduced by one day for each day by which such execution and delivery follows the expiration of such 30-day period. Notwithstanding

any contrary provision hereof, Tenant may not examine Landlord’s records or dispute any Statement if any Rent remains unpaid past its due date. If, for any Expense Year, Landlord and Tenant determine that the sum of Tenant’s Share of the actual Expense Excess plus Tenant’s Share of the actual Tax Excess is less or more than the amount reported, Tenant shall receive a credit in the amount of its overpayment against Rent that or next due hereunder, or pay Landlord the amount of its underpayment with the Rent next due hereunder; provided, however, that if this Lease has expired or terminated and Tenant has vacated the Premises, Landlord shall pay Tenant the amount of its overpayment (less any Rent due), or Tenant shall pay Landlord the amount of is underpayment within 30 days after such determination.

5. USE; COMPLIANCE WITH LAWS.

5.1 Tenant shall not (a) use the Premises for any purpose other than the Permitted Use, or (b) do anything in or about the Premises that violates any of the Rules and Regulations, damages the reputation of the Project, interferes with, injures or annoys other occupants of the Building, or constitutes a nuisance. Tenant, at its expense, shall comply with all Laws relating to (i) the operation of its business at the Project, (ii) the use, condition, configuration or occupancy of the Premises, or (iii) the Building systems located in or exclusively serving the Premises. If, in order to comply with any such Law, Tenant must obtain or deliver any permit, certificate or other document evidencing such compliance, Tenant shall provide a copy of such document to Landlord promptly after obtaining or delivering it. If a change to any Common Area, the Building structure, or any Building system located outside of and not exclusively serving the Premises becomes required under Law (or if any such requirement is enforced) as a result of any Tenant-Insured Improvement (defined in Section 10.2.2), the installation of any trade fixture, or any use of the Premises other than general office use, Tenant, upon demand, shall (x) at Landlord’s option, either make such change at Tenant’s cost or pay Landlord the cost of making such change, and (y) pay Landlord a coordination fee equal to 10% of the cost of such change. As used herein, “Law” means any existing or future law, ordinance, regulation or requirement of any governmental authority having jurisdiction over the Project or the parties. Landlord represents and warrants to Tenant that, as of the date hereof, Landlord has not received written notice from any governmental agency that the existing configuration or condition of the Premises violates applicable Law.

5.2 Landlord, at its expense (subject to Section 4), shall cause the Base Building and the Common Areas to comply with all Laws (including the Americans with Disabilities Act (“ADA”)) to the extent that (a) such compliance is necessary for Tenant to use the Premises for general office use in a normal and customary manner and for Tenant’s employees and visitors to have reasonably safe access to and from the Premises, or (b) Landlord’s failure to cause such compliance would impose liability upon Tenant under Law; provided, however, that Landlord shall not be required to cause such compliance to the extent non-compliance (x) is triggered by any matter that is Tenant’s responsibility under Section 5.1 or 7.3 or any other provision hereof, or (y) arises under any provision of the ADA other than Title III thereof. Notwithstanding the foregoing, Landlord may contest any alleged violation in good faith, including by applying for and obtaining a waiver or deferment of compliance, asserting any defense allowed by Law, and appealing any order or judgment to the extent permitted by Law; provided, however, that after exhausting any rights to contest or appeal, Landlord shall perform any work necessary to comply with any final order or judgment.

Tenant shall not, without Landlord’s prior consent, use equipment that may affect the temperature maintained by the air conditioning system or consume above-Building-standard amounts of any water furnished for the Premises by Landlord pursuant to Section 6.1. If Tenant’s consumption of electricity or water exceeds the rate Landlord reasonably deems to be standard for the Building, Tenant shall pay Landlord, upon billing, the cost of such excess consumption, including any costs of installing, operating and maintaining any equipment that is installed in order to supply or measure such excess electricity or water. For purposes of the preceding sentence, any consumption of electricity in a computer server room shall be deemed to exceed the standard rate for the Building. The connected electrical load of Tenant’s incidental-use equipment shall not exceed the Building-standard electrical design load, and Tenant’s electrical usage shall not exceed the capacity of the feeders to the Project or the risers or wiring installation.

6.3 Interruption. Any failure to furnish, delay in furnishing, or diminution in the quality or quantity of any service resulting front any application of Law, failure of equipment, performance of maintenance, repairs, improvements or alterations, utility interruption, or event of Force Majeure (each, a “Service Interruption”) shall not render Landlord liable to Tenant, constitute a constructive eviction, or excuse Tenant from any obligation hereunder. Notwithstanding the foregoing, if all or a material portion of the Premises is made untenantable or inaccessible for more than five (5) consecutive business days after notice from Tenant to Landlord by a Service Interruption that Landlord can correct through reasonable efforts, then, as Tenant’s solo remedy, Monthly Rent shall ▇▇▇▇▇ for the period beginning on the day immediately following such 5-business-day period and ending on the day such Service Interruption ends, but only in proportion to the percentage of the rentable square footage of the Premises made untenantable or inaccessible.

7.1 Repairs. Subject to Section 11, Tenant, at its expense, shall perform all maintenance and repairs (including replacements) to the Premises, and keep the Premises in as good condition and repair as when Tenant took possession and as thereafter improved by Landlord and/or Tenant, except for reasonable wear and tear and repairs that are Landlord’s express responsibility hereunder. Tenant’s maintenance and repair obligations shall include (a) all leasehold improvements in the Premises, whenever and by whomever installed or paid for, including any Tenant Improvements, any Alterations (defined in Section 7.2), and any leasehold improvements installed pursuant to any prior lease, but excluding the Base Building (the “Leasehold Improvements”); (b) all supplemental heating, ventilation and air conditioning units, kitchens (including hot water heaters, dishwashers, garbage disposals, insta-hot dispensers, and plumbing) and similar facilities exclusively serving Tenant, whether located inside or outside of the Premises, and whenever and by whomever installed or paid for; and (c) all Lines (defined in Section 23). Notwithstanding the foregoing, if Tenant is in Default or in the case of an emergency, Landlord may, at its option, perform such maintenance end repairs on Tenant’s behalf, in which case Tenant shall pay Landlord, upon demand, the cost of such work plus a coordination fee equal to 10% of such cost. Landlord shall perform all maintenance and repairs to (i) the roof and exterior walls and windows of the Building, (ii) the Base Building, and (iii) the Common Areas. As used herein, “Base

Notwithstanding the foregoing, Landlord’s prior consent shall not be required for any Alteration that is decorative only (e.g., carpet installation or painting) and not visible from outside the Premises, provided that Landlord receives 10 business days’ prior notice. For any Alteration, (a) Tenant, before commencing work, shall deliver to Landlord, and obtain Landlord’s approval of, plans and specifications; (b) Landlord, in its discretion, may require Tenant to obtain security for performance reasonably satisfactory to Landlord; (c) Tenant shall deliver to Landlord “as built” drawings (in CAD format, if requested by Landlord), completion affidavits, full and final lien waivers, and all governmental approvals; and (d) Tenant shall pay Landlord upon demand (i) Landlord’s reasonable out-of-pocket expenses incurred in reviewing the work, and (ii) a coordination the equal to 5% of the cost of the work; provided, however, that this clause (d) shall not apply to any Tenant Improvements.

If, as a result of any Tenant Work, Landlord becomes required under Law to perform any inspection, give any notice, or cause such Tenant Work to be performed in any particular manner, Tenant shall comply with such requirement and promptly provide Landlord with reasonable documentation of such compliance. Landlord’s approval of Tenant’s plans and specifications shall not relieve Tenant from any obligation under this Section 7.3. In performing any Tenant Work, Tenant shall not use contractors, services, labor, materials or equipment that, in Landlord’s reasonable Judgment, would disturb labor harmony with any workforce or trades engaged in performing other work or services at the Project.

8. LANDLORD’S PROPERTY. All Leasehold Improvements shall become Landlord’s property upon installation and without compensation to Tenant. Notwithstanding the foregoing, if any Tenant-Insured Improvements are not, in Landlord’s reasonable judgment, Building-standard, then before the expiration or earlier termination hereof, Tenant shall, at Landlord’s election, either (a) at Tenant’s expense, and except as otherwise notified by Landlord, remove such Tenant-Insured Improvements (other than the Excluded Items (defined below)), repair any resulting damage to the Premises or Building, and restore the affected portion of the Premises to its condition existing before the installation of such Tenant-Insured Improvements (or, at Landlord’s election, to a Building-standard tenant-improved condition as reasonably determined by Landlord), or (b) pay Landlord an amount equal to the estimated cost of such work as reasonably determined by Landlord.

Tenant shall indemnify, defend, protect, and hold the Landlord Parties harmless from any obligation, loss, claim, action, liability, penalty, damage, cost or expense (including reasonable attorneys’ and consultants’ fees and expenses) (each, a “Claim”) that is imposed or asserted by any third party and arises from (a) any cause in, on or about the Premises, (b) occupancy of the Premises by, or any negligence or willful misconduct of, Tenant, any party claiming by, through or under Tenant, their (direct or indirect) owners, or any of their respective beneficiaries, trustees, officers, directors, employees, agents, contractors, licensees or invitees, or (c) any breach by Tenant of any representation, covenant or other term contained basin, except to the extent such Claim arises from the negligence or willful misconduct of any Landlord Party.

Such insurance shall be written on a special cause of loss form for physical loss or damage, for the full replacement cost value (subject to reasonable deductible amounts) new without deduction for depreciation of the covered items and in amounts that meet any co-insurance clauses of the policies of insurance, and shall include coverage for damage or other loss caused by fire or other peril, including vandalism and malicious mischief theft, water damage of any type, including sprinkler leakage, bursting or stoppage of pipes, and explosion, and providing business interruption coverage for a period of six (6) months.

10.2.3 Workers’ Compensation statutory limits and Employers’ Liability limits of $1,000,000.

10.3 Form of Policies. The minimum limits of insurance required to be carried by Tenant shall not limit Tenant’s liability. Such insurance shall be issued by an insurance company than has an A.M. Best rating of not less than A-VIII and shall be in form and content reasonably acceptable to Landlord. Tenant’s Commercial General Liability Insurance shall (a) name the Landlord Parties and any other party designated by Landlord (“Additional Insured Parties”) as additional insureds; and (b) be primary insurance as to all claims thereunder and provide that any insurance carried by Landlord is excess and non-contributing with Tenant’s insurance.

Each party waives, and shall cause its insurance carrier to waive, any right of recovery against the other party, any of its (direct or indirect) owners, or any of their respective beneficiaries, trustees, officers, directors, employees or agents for any loss of or damage to property which loss or damage is (or, if the insurance required hereunder had been carried, would have been) covered by property insurance. For purposes of this Section 10.4 only, (a) any deductible with respect to a party’s insurance shall be deemed covered by, and recoverable by such party under, valid and collectable policies of insurance, and (b) any contractor retained by landlord to install, maintain or monitor a fire or security alarm for the Building shall be deemed an agent of Landlord.

10.5 Additional Insurance Obligations. Tenant shall maintain such increased amounts of the insurance requited to be carried by Tenant under this Section 10, and such other types and amounts of insurance covering the Premises and Tenant’s operations therein, as may be reasonably requested (not more than once in any 36-month period) by Landlord, but not in excess of the amounts and types of insurance then being required by landlords of buildings comparable to and in the vicinity of the Building.

10.6 Landlord’s Insurance. Landlord shall maintain the following insurance, together with such other insurance coverage as Landlord, in its reasonable judgment, may elect to maintain, the premiums of which shall be included in Expenses: (a) Commercial General Liability insurance applicable to the Property, Building and Common Areas providing, on an occurrence basis, a minimum combined single limit of at least $3,000,000.00; (b) Special Cause of Loss Insurance on the Building at replacement cost value as reasonably estimated by Landlord; (e) Worker’s Compensation Insurance to the extent required by Law; and (d) Employers Liability Coverage to the extent required by Law.

11. CASUALTY DAMAGE. With reasonable promptness after discovering any damage to the Premises, or to the Common Areas necessary for access to the Premises, resulting from any fire or other casualty (a “Casualty”), Landlord shall notify Tenant of Landlord’s reasonable estimate of the time required to substantially complete repair of such damage (the “Landlord Repairs”). If, according to

such estimate, the Landlord Repairs cannot be substantially completed within 210 days after they are commenced, either party may terminate this Lease upon 60 days’ notice to the other party delivered within 10 days after Landlord’s delivery of such estimate. Within 90 days after discovering any damage to the Project resulting from any Casualty, Landlord may, whether or not the Premises is affected, terminate this Lease by notifying Tenant if (i) any Security Holder terminates any ground lease or requires that any insurance proceeds be used to pay any mortgage debt; (ii) any damage to Landlord’s property is not fully covered by Landlord’s insurance policies; (iii) Landlord decides to rebuild the Building or Common Areas so that it or they will be substantially different structurally or architecturally; (iv) the damage occurs during the lest 12 months of the Term; or (v) any owner, other than Landlord, of any damaged portion of the Project does not intend to repair such damage; provided, however, that Landlord may not terminate this Lease pursuant to this sentence unless the Premises has been materially damaged or Landlord also exercises all rights it may have acquired as a result of the Casualty to terminate any other similarly situated leases of space in the Building. If this Lease is not terminated pursuant to this Section 11, Landlord shall promptly and diligently perform the Landlord Repairs, subject to reasonable delays for insurance adjustment and other events of Force Majeure. The Landlord Repairs shall restore the Premises and the Common Areas necessary for access to the Premises to substantially the same condition that existed when the Casualty occurred, except for (a) any modifications required by Law or any Security Holder, and (b) any modifications to the Common Areas that are deemed desirable by Landlord, are consistent with the character of the Project, and do not materially impair access to the Premises. Notwithstanding Section 10.4, Tenant shall assign to Landlord (or its designee) all insurance proceeds payable to Tenant under Tenant’s insurance required under Section 10.2 with respect to any Tenant-Insured Improvements and trade fixtures, and if the estimated or actual cost of restoring any Tenant-Insured Improvements and trade fixtures exceeds the insurance proceeds received by Landlord from Tenant’s insurance carrier, Tenant shall pay such excess to Landlord within 15 days after Landlord’s demand. No Casualty and no restoration performed as required hereunder shall render Landlord liable to Tenant, constitute a constructive eviction, or excuse Tenant from any obligation hereunder; provided, however, that if the Premises or any Common Area necessary for Tenant’s access to the Premises is damaged by a Casualty, than, during any time that, as a result of such damage, any portion of the Premises is untenantable or inaccessible and is not occupied by Tenant, Monthly Rent shall be abated in proportion to the rentable square footage of such portion of the Premises.

12. NONWAIVER. No provision hereof shall be deemed waived by either party unless it is waived by such party expressly and in writing, and no waiver of any breach of any provision hereof shall be deemed a waiver of any subsequent breach of such provision or any other provision hereof. Landlord’s acceptance of Rent shall not be deemed a waiver of any preceding breach of any provision hereof, other than Tenant’s failure to pay the particular Rent an accepted, regardless of Landlord’s knowledge of such preceding breach at the time of such acceptance. No acceptance of payment of an amount less than the Rent due hereunder shall be deemed a waiver of Landlord’s right to receive the full amount of Rent due, whether or not any endorsement or statement accompanying such payment purports to effect an accord and satisfaction. No receipt of monies by Landlord from Tenant after the giving of any notice, the commencement of any suit, the issuance of any final judgment, or the termination hereof shall affect such notice, suit or judgment, or reinstate or extend the Term or Tenant’s right of possession hereunder.

13. CONDEMNATION. If any part of the Premises, Building or Project is taken for any Public or quasi-public use by power of eminent domain or by private purchase in lien thereof (a “Taking”) for more than 120 consecutive days, Landlord may terminate this Lease. If more than 25% of the rentable square footage of the Premises is Taken, or access to the Premises is substantially impaired as a result of a Taking, for more then 120 consecutive days, Tenant may terminate this Lease. Any such termination shall be effective as of the date possession most be surrendered to the authority, and the terminating party shall provide termination notice to the other party within 45 days after receiving written notice of such surrender date. Except as provided above in this Section 13, neither party may terminate this Lease as a

result of a Taking. Tenant shall not assert any claim for compensation because of any Taking; provided, however, that Tenant may file a separate claim for any Taking of Tenant’s personal property or any fixtures that Tenant is entitled to remove upon the expiration hereof; and for moving expenses, so long as such claim does not diminish the award available to Landlord or any Security Holder and is payable separately to Tenant. If this Lease is terminated pursuant to this Section 13, all Rent shall be apportioned as of the date of such termination. If a Taking occurs and this Lease is not so terminated, Monthly Rent shall be abated for the period of such Taking in proportion to the percentage of the rentable square footage of the Premises, if any, that is subject to, or rendered inaccessible by, such Taking.

14. ASSIGNMENT AND SUBLETTING.

14.1 Transfers. Tenant shall not, without Landlord’s prior consent, assign, mortgage, pledge, hypothecate, encumber, permit any lien to attach to, or otherwise transfer this Lease or any interest hereunder, permit any assignment or other transfer hereof or any interest hereunder by operation of law, enter into any sublease or license agreement, otherwise permit the occupancy or use of any part of the Premises by any persons other than Tenant and its employees and connectors, or permit a Change of Control (defined in Section 14.6) to occur (each, a “Transfer”). If Tenant desires Landlord’s consent to any Transfer, Tenant shall provide Landlord with (i) notice of the terms of the proposed Transfer, including its proposed effective date (the “Contemplated Effective Date”), a description of the portion of the Premises to be transferred (the “Contemplated Transfer Space”), a calculation of the Transfer Premium (defined in Section 14.3), and a copy of all existing executed and/or proposed documentation pertaining to the proposed Transfer, and (ii) current financial statements of the proposed transferee (or, in the case of a Change of Control, of the proposed new controlling party(ies)) certified by an officer or owner thereof and any other information reasonably required by Landlord in order to evaluate the proposed Transfer (collectively, the “Transfer Notice”).

Tenant shall pay Landlord a fee of $1,500.00 for Landlord’s review of any proposed Transfer, whether or not Landlord consents to it.

14.2 Landlord’s Consent. Subject to Section 14.4, Landlord shall not unreasonably withhold its consent to any proposed Transfer. Without limiting other reasonable grounds for withholding consent, it shall be deemed reasonable for Landlord to withhold consent to a proposed Transfer if:

14.2.1 The proposed transferee is not a party of reasonable financial strength in light of the responsibilities to be undertaken in connection with the Transfer on the date the Transfer Notice is received; or

14.2.2 In landlord’s reasonable judgment, the proposed transferee has a character or reputation or is engaged in a business that is not consistent with the quality of the Building or the Project or

14.2.3 The proposed transferee is a govenmental agency or instrumentality thereof whose occupancy of the Premises or any portion thereof generates, or is likely to generate, disproportionately high (in comparison to all of the tenants) visitation of the Premises or any portion thereof by members of the public, including, without limitation, situations where visitors will likely form waiting lines or loiter in Common Areas or cause disproportionately high visitation of the Premises; or

14.2.4 Intentionally Omitted; or

14.2.5 The proposed transferee, on the date the Transfer Notice is received, leases or occupies (or, at any time during the 6-month period ending on the date the Transfer Notice is received, has negotiated with Landlord to lease) space in the Project and as of the Contemplated Effective Date, Landlord will have vacant space that is at least comparable to the Contemplated Transfer Space in the Project.

Notwithstanding any contrary provision hereof, (a) if Landlord consents to any Transfer pursuant to this Section 14.2 but Tenant does not enter into such Transfer within six (6) months thereafter, such consent shall no longer apply and such Transfer shall not be permitted unless Tenant again obtains Landlord a consent thereto pursuant and subject to the terms of this Section 14; and (b) if Landlord unreasonably withholds its consent under this Section 14.2, Tenant’s sole remedies shall be contract damages (subject to Section 20) or specific performance, and Tenant waives all other remedies, including any right to terminate this Lease.

14.3 Transfer Premium. If Landlord consents to a Transfer, Tenant shall pay Landlord an amount equal to 50% of any Transfer Premium (defined below). As used herein, “Transfer Premium” means (a) in the case of an assignment, any consideration (including payment the Leasehold Improvements) paid by the assignee for such assignment, less any reasonable and customary expenses directly incurred by Tenant on account of such assignment, including brokerage fees, legal fees, and Landlord’s review fee; (b) in the case of a sublease, license or other occupancy agreement, for each month of the term of such agreement, the amount by which all rent and other consideration paid by the transferee to Tenant pursuant to such agreement (less all reasonable and customary expenses directly incurred by Tenant on account of such agreement, including brokerage fees, legal fees, construction costs and Landlord’s review fee, as amortized on a monthly, straight-line basis over the term of such agreement) exceeds the Monthly Rent payable by Tenant hereunder with respect to the Contemplated Transfer Space; and (c) in the case of a Change of Control, any consideration (including payment for Leasehold Improvements) paid by the new controlling party(ies) to the prior controlling party(ies) on account of this Lease, less Landlord’s review fee and, to the extent reasonably allocable to this Lease, any other reasonable and customary expenses directly incurred by such prior controlling party(ies) on account of such Change of Control. Payment of Landlord’s share of the Transfer Premium shall be made (x) in the case of an assignment or a Change of Control, within 10 days after Tenant or the prior controlling party(ies), as the case may be, receive(s) the consideration described above, and (y) in the case of a sublease, license or other occupancy agreement, for each month of the term of such agreement, within five (5) business days after Tenant receives the rent and other consideration described above.

14.4 Landlord’s Right to Recapture. Notwithstanding any contrary provision hereof; except in the case of a Permitted Transfer (defined in Section 14.8), Landlord, by notifying Tenant within 10 business days after receiving the Transfer Notice, may terminate this Lease with respect to the Contemplated Transfer Space as of the Contemplated Effective Date; provided, however, that such termination shall not be effective if Tenant. by notifying Landlord within five (5) days of receiving Landlord’s notice of termination, withdraws the Transfer Notice. If Tenant does not timely withdraw the Transfer Notion, and if the Contemplated Transfer Space is less than the entire Premises, then Base Rent, Tenant’s Share, and the number of parking spaces to which Tenant is entitled under Section 1.9 shall be deemed adjusted on the basis of the percentage of the rentable square footage of the Premises retained by Tenant. Upon request of either party, the parties shall execute a written agreement prepared by Landlord memorializing such termination.

14.5 Effect of Consent. If Landlord consents to a Transfer, (i) such consent shall not be deemed a consent to any further Transfer, (ii) Tenant shall deliver to Landlord, promptly after execution, an executed copy of all documentation pertaining to the Transfer in form reasonably acceptable to Landlord, and (iii) Tenant shall deliver to Landlord, upon Landlord’s request, a complete statement, certified by an

independent CPA or Tenant’s chief financial officer, setting forth in detail the computation of any Transfer Premium. In the case of an assignment, the assignee shall assume in writing, for Landlord’s benefit, all of Tenant’s obligations hereunder. No Transfer, with or without Landlord’s consent, shall relieve Tenant or any guarantor hereof from any liability hereunder. Notwithstanding any contrary provision hereof Tenant, with or without Landlord’s consent, shall not enter into, or permit any party claiming by, through or under Tenant to enter into, any sublease, license or other occupancy agreement that provides for payment based in whole or in part on the net income or profit of the subtenant, licensee or other occupant thereunder.

14.6 Change of Control. As used herein, “Change of Control” means (a) if Tenant is a closely held professional service firm, the withdrawal or change (whether voluntary, involuntary or by operation of law) of 50% or more of its equity owners within a 12-month period; and (b) in all other cases, any transaction(s) resulting in the acquisition of a Controlling interest (defined below) by one or more parties that did not own a Controlling Interest immediately before such transaction(s). As used herein, “Controlling Interest” means any direct or indirect equity or beneficial ownership interest in Tenant that confers upon its holder(s) the direct or indirect power to direct the ordinary management and policies of Tenant, whether through the ownership of voting securities, by contract or otherwise (but not through the ownership of voting securities listed on a recognized securities exchange).

14.7 Effect of Default. If Tenant is in Default, Landlord is irrevocably authorized, as Tenant’s agent and attorney-in-fact, to direct any transferee under any sublease, license or other occupancy agreement to make all payments under such agreement directly to Landlord (which Landlord shall apply towards Tenant’s obligations hereunder) until such Default is cured. Such transitive shall rely upon any representation by Landlord that Tenant is in Default, whether or not confirmed by Tenant.

14.8 Permitted Transfers. Notwithstanding any contrary provision hereof if Tenant is not in Default, Tenant may, without Landlord’s consent pursuant to Section 14.1, permit a Change of Control to occur or assign this Lease to (a) an Affiliate of Tenant (other than pursuant to a merger or consolidation), (b) a successor to Tenant by merger or consolidation, or (c) a successor to Tenant by purchase of all or substantially all of Tenant’s assets (a “Permitted Transfer”), provided that (i) at least 10 business days before the Transfer, Tenant notifies Landlord of such Transfer and delivers to Landlord any documents or information reasonably requested by Landlord relating thereto, including reasonable documentation that the Transfer satisfies the requirements of this Section 14.8; (ii) in the case of an assignment pursuant to clause (a) or (c) above, the assignee executes and delivers to Landlord, at least 10 business days before the assignment, a commercially reasonable instrument pursuant to which the assignee assumes, for Landlord’s benefit, all of Tenant’s obligations hereunder, (iii) in the case of an assignment pursuant to clause (b) above, (A) the successor entity has a net worth (as determined in accordance with GAAP, but excluding intellectual property and any other intangible assets (“Net Worth”)) immediately after the Transfer that is not less than the lesser of (1) the Net Worth of Tenant immediately before the Transfer and (2) the Net Worth of Tenant as of the date of this Lease, and (B) if Tenant is a closely held professional service firm, at least 50% of its equity owners existing 12 months before the Transfer are also equity owners of the successor entity; (iv) except in the case of a Change of Control, the transferee is qualified to conduct business in the State of California; (v) in the case of a Change of Control, (A) Tenant is not a closely held professional service firm, and (B) Tenant’s Net Worth immediately after the Change of Control is not less than its Net Worth immediately before the Change of Control; and (vi) the Transfer is made for a good faith operating business purpose and not in order to evade the requirements of this Section 14. As used herein, “Affiliate” means, with respect to any party, a person or entity that controls, is under common control with, or is controlled by such party.

15. SURRENDER. Upon the expiration or earlier termination hereof, and subject to Sections 8 and 11 and this Section 15, Tenant shall surrender possession of the Premises to Landlord in as good condition

and repair as when Tenant took possession and as thereafter improved by Landlord and/or Tenant, except for reasonable wear and tear, Casualty and repairs that are Landlord’s express responsibility hereunder. Before such expiration or termination, Tenant, without expense to Landlord, shall (a) remove from the Premises all debris and rubbish and all furniture, equipment, trade fixtures, Lines, free-standing cabinet work, movable partitions and other articles of personal property that are owned or placed in the Premises by Tenant or any party claiming by, through or under Tenant (except for any Lines not required to be removed under Section 23), and (b) repair all damage to the Premises and Building resulting from such removal. If Tenant fails to timely perform such removal and repair, Landlord may do so at Tenant’s expense (including storage costs). If Tenant fails to remove such property from the Premises, or from storage, within 30 days after notice from Landlord, any part of such property shall be deemed, at Landlord’s option, either (x) conveyed to Landlord without compensation, or (y) abandoned.

16. HOLDOVER. If Tenant fails to surrender the Premises upon the expiration or earlier termination hereof, Tenant’s tenancy shall be subject to the terms and conditions hereof; provided, however, that such tenancy shall be a tenancy at sufferance only, for the entire Premises, and Tenant shall pay Monthly Rent (on a per-month basis without reduction for any partial month) at a rate equal to 150% of the Monthly Rent applicable during the last calendar month of the Term. Nothing in this Section 16 shall limit Landlord’s rights or remedies or be deemed a consent to any holdover. If Landlord is unable to deliver possession of the Premises to a new tenant or to perform improvements for a new tenant as a result of Tenant’s holdover, Tenant shall be liable for all resulting damages, including lost profits, incurred by Landlord.

17. SUBORDINATION; ESTOPPEL CERTIFICATES. This Lease shall be subject and subordinate to all existing and future ground or underlying leases, mortgages, trust deeds and other encumbrances against the Building or Project, all renewals, extensions, modifications, consolidations and replacements thereof (each, a “Security Agreement”), and all advances made upon the security of such mortgages or trust deeds, unless in each case the holder of such Security Agreement (each, a “Security Holder”) requires in writing that this Lease be superior thereto. Upon any termination or foreclosure (or any delivery of a deed in lieu of foreclosure) of any Security Agreement, Tenant, upon request, shall attorn, without deduction or set-off, to the Security Holder or purchaser or any successor thereto and shall recognize such party as the lessor hereunder provided that such party agrees not to disturb Tenant’s occupancy so long as Tenant timely pays the Rent and otherwise performs its obligations hereunder. Within 10 days after request by Landlord, Tenant shall execute such further instruments as Landlord may reasonably deem necessary to evidence the subordination or superiority of this Lease to any Security Agreement. Tenant waives any right it may have under Law to terminate or otherwise adversely affect this Lease or Tenant’s obligations hereunder upon a foreclosure. Within 10 business days after Landlord’s request, Tenant shall execute and deliver to Landlord a commercially reasonable estoppel certificate in favor of such parties as Landlord may reasonably designate, including current and prospective Security Holders and prospective purchasers.

18. ENTRY BY LANDLORD.

18.1 At all reasonable times and upon reasonable notice to Tenant, or in an emergency, Landlord may enter the Premises to (i) inspect the Premises; (ii) show the Premises to prospective purchasers, current or prospective Security Holders or insurers, or, during the last 12 months of the Term (or while an uncured Default exists), prospective tenants; (iii) post notices of non-responsibility; or (iv) perform maintenance, repairs or alterations. At any time and without notice to Tenant, Landlord may enter the Premises to perform required services provided, however, that, except in an emergency, Landlord shall provide Tenant with reasonable prior notice (which notice, notwithstanding Section 25.1 may be delivered by e-mail, fax, telephone or orally and in person) of any entry to perform a service that is not performed on a monthly or more frequent basis. If reasonably necessary, Landlord may temporarily close

any portion of the Premises to perform maintenance, repairs or alterations. In an emergency, Landlord may use any means it deems proper to open doors to and in the Premises. Except in an emergency, Landlord shall use reasonable efforts to minimize interference with Tenant’s use of the Premises. Except in an emergency, Tenant may have one of its employees accompany Landlord if Tenant makes such employee available when Landlord enters the Premises. No entry into or closure of any portion of the Premises pursuant to this Section 18 shall render Landlord liable to Tenant, constitute a constructive eviction, or excuse Tenant from any obligation hereunder.

18.2 Tenant, at its expense, may provide its own locks to an area within the Premises (“Secured Area”) containing not more than 10% of the total rentable square feet. Upon the expiration or earlier termination of this Lease or Tenant’s right to possession, Tenant shall surrender to Landlord all keys to the Secured Area. Other than in an emergency, Landlord shall not enter the Secured Area without Tenant’s consent, which shall not be unreasonably withheld. Landlord shall comply with all reasonable security measures pertaining to the Secured Area. If Landlord determines, in its sole discretion, that an emergency requires that Landlord enter the Secured Area, then (a) Landlord may forcibly enter the Secured Area; (b) Landlord shall have no liability to Tenant with respect to such entry; and (c) Tenant shall pay all reasonable expenses incurred by Landlord in repairing any damage to the Premises resulting from such entry. Notwithstanding any contrary provision hereof, Landlord shall have no obligation to provide janitorial service in the Secured Area.

19. DEFAULTS; REMEDIES.

19.1 Events of Default. The occurrence of any of the following shall constitute a “Default”:

19.1.1 Any failure by Tenant to pay any Rent when due unless such failure is cured within five (5) business days after notice; or

19.1.2 Except where a specific time period is otherwise set forth for Tenant’s cure herein (in which event Tenant’s failure to cure within such time period shall be a Default), and except as otherwise provided in this Section 19.1, any breach by Tenant of any other provision hereof where each breach continues for 30 days after notice from Landlord; provided that if such breach cannot reasonably be cured within such 30-day period, Tenant shall not be in Default as a result of such breach if Tenant diligently commences such cure within such period, thereafter diligently pursues such cure, and completes such cure within 60 days after Landlord’s notice; or

19.1.3 Intentionally Omitted; or

19.1.4 Any breach by Tenant of Sections 5, 14, 17 or 18 where such breach continues for more than two (2) business days after notice from Landlord; or

19.1.5 Tenant becomes in breach of Section 25.3.

If Tenant, by repeating substantially the same act or omission, breaches a particular provision hereof (other than a provision requiring payment of Rent), and Landlord notifies Tenant of such breach, on three (3) separate occasions during any 12-month period, and if such breaches are collectively material, that Tenant’s subsequent breach of such provision by commission of substantially the same act or omission shall be, at Landlord’s option, an incurable Default. The notice periods provided herein are in lien of, and not in addition to, any notice periods provided by Law, and Landlord shall not be required to give any additional notice in order to be entitled to commence an unlawful detainer proceeding.

19.2 Remedies Upon Default. Upon any Default, Landlord shall have, in addition to any other remedies available to Landlord at law or in equity (which shall be cumulative and nonexclusive), the option to pursue any one or more of the following remedies (which shall be cumulative and nonexclusive) without any notice or demand:

19.2.1 Landlord may 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 it may have for possession or arrearages in Rent, but in compliance with applicable Law, 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:

(a) The worth at the time of award of the unpaid Rent which has been earned at the time of such termination; plus

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

(c) The worth at the time of award of the amount by which the unpaid Rent for the balance of the Term after the time of award exceeds the amount of such Rent loss that Tenant proves could have been reasonably avoided; plus

(d) Any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations hereunder or which in the ordinary course of things would be likely to result therefrom, including brokerage commissions, advertising expenses, expenses of remodeling any portion of the Premises for a new tenant (whether for the same or a different use), and any special concessions made to obtain a new tenant; plus

(e) At Landlord’s option, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by Law.

As used in Sections 19.2.1(a) and (b), the “worth at the time of award” shall be computed by allowing interest at a rate per annum equal to the lesser of (i) the annual “Bank Prime Loan” rate cited in the Federal Reserve Statistical Release Publication G.13(415), published on the first Tuesday of each calendar month (or such other comparable index as Landlord shall reasonably designate if such rate ceases to be published) plus two (2) percentage points, or (b) the highest rate permitted by Law. As used in Section 19.2.1(c) the “worth at the time of award” shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus 1%.

19.2.2 Landlord shall have the remedy described in California Civil Code § 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 default by Tenant, Landlord may from time to time, without terminating this Lease, enforce all of its rights and remedies hereunder, including the right to recover all Rent as it becomes due.

19.2.3 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 19.2.1 and 19.2.2, or any Law or other provision hereof), without prior demand or notice except as required by 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.

19.3 Efforts to Relet. Unless Landlord provides Tenant with express notice to the contrary, no re-entry, repossession, repair, maintenance, change, alteration, addition, relenting, appointment of a receiver or other action or omission by Landlord shall (a) 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, or (b) operate to release Tenant from any of its obligations hereunder. Tenant waives, for Tenant and for all those claiming by, through or under Tenant, California Civil Code § 3275 and California Code of Civil Procedure §§ 1174(c) and 1179 and any existing or future rights to redeem or reinstate, by order or judgment of any court or by any legal process or writ, this Lease or Tenant’s right of occupancy of the Premises after any termination hereof.

19.4 Landlord Default. Landlord shall not be in default hereunder unless it fails to begin within 30 days after notice from Tenant, or fails to pursue with reasonable diligence thereafter, the cure of any breach by Landlord of its obligations hereunder. Before exercising any remedies for a default by Landlord, Tenants shall give notice and a reasonable time to one to any Security Holder of which Tenant has been notified.

20. EXCULPATION.

20.1 Notwithstanding any contrary provision hereof, (a) the liability of the Landlord Parties to Tenant shall be limited to an amount equal to the Landlords interest in the Building; (b) Tenant shall look solely to Landlord’s interest in the Building for the recovery of any judgment or award against any Landlord Party; (c) no Landlord Party shall have any personal liability for any judgment or deficiency, and Tenant waives and releases such personal liability on behalf of itself and all parties claiming by, through or under Tenant; and (d) no Landlord Party shall be liable for any injury or damage to, or interference with, Tenant’s business, including loss of profits, loss of rents or other revenues, loss of business opportunity, loss of goodwill or loss of use, or for any form of special or consequential damage.

20.2 Notwithstanding any contrary provision hereof; no Tenant Party shall be liable for any form of special or consequential damage, except as provided in Section 16.

21. SECURITY DEPOSIT. Concurrently with its execution and delivery hereof; Tenant shall deposit with Landlord the Security Deposit, if any, as security for Tenant’s performance of its obligations hereunder. If Tenant breaches any provision hereof, Landlord may, at its option, without notice to Tenant, apply all or part of the Security Deposit to pay any past-due Rent, cure any breach by Tenant, or compensate Landlord for any other loss or damage caused by such breach. If Landlord so applies any portion of the Security Deposit, Tenant, within three (3) days after demand therefor, shall restore the Security Deposit to its original amount. The Security Deposit is not an advance payment of Rent or measure of damages. Any unapplied portion of the Security Deposit shall be returned to Tenant within 60 days after the latest to occur of (a) the expiration of the Term, (b) Tenant’s surrender of the Premises as required hereunder, or (c) determination of the final Rent due from Tenant. Landlord shall not be required to keep the Security Deposit separate from its other accounts.

22. RELOCATION. Landlord, after giving notice, may move Tenant to other space in the Project comparable in size and utility to the Premises. In such event, all terms hereof shall apply to the new space, except that Base Rent and Tenant’s Share shall not increase as a result of such relocation. The new space must contain simpler finishes (subject to commercial availability) as the Premises and the same number of work stations, offices, breakrooms and reception areas as are contained in the Premises as of the date Tenant receives Landlord’s notice of relocation. In addition, Landlord shall move Tenant’s

effects to the new space. Landlord shall reimburse Tenant for Tenant’s reasonable moving, re-cabling and stationery-replacement costs. The parties shall execute a written agreement prepared by Landlord memorializing the relocation.

23. COMMUNICATIONS AND COMPUTER LINES. All Lines installed pursuant to this Lease shall be (a) installed in accordance with Section 7; and (b) clearly marked with adhesive plastic labels (or plastic tags attached to such Lines with wire) to show Tenant’s name, suite number, and the purpose of such Lines (i) every six (6) feet outside the Premises (including the electrical room risers and any Common Areas), and (ii) at their termination points. Landlord may designate specific contractors for work relating to vertical Lines. Sufficient spare cables and space for additional cables shall be maintained for other occupants, as reasonably determined by Landlord. Unless otherwise notified by Landlord, Tenant, at its expense and before the expiation or earlier termination hereof, shall remove all Lines and repair any resulting damage. As used herein, “Lines” means all communications or computer wires and cables serving the Premises, whenever and by whomever installed or paid for, including any such wires or cables installed pursuant to any prior lease.

24. PARKING. Tenant may park in the Building’s parking facilities (the “Parking Facility”), in common with other tenants of the Building, upon the following terms and conditions. Tenant shall not use more than the number of unreserved and/or reserved parking spaces set forth in Section 1.9, Landlord shall not be liable to Tenant, nor shall this Lease be affected, if any parking is impaired by (or any parking charges are imposed as a result of) any Law. Tenant shall comply with all rules and regulations established by Landlord from time to time for the orderly operation and use of the Parking Facility, including any sticker or other identification system and the prohibition of vehicle repair and maintenance activities in the Parking Facility. Landlord may, in its discretion, allocate and assign parking passes among Tenant and the other tenants in the Building. Tenant’s use of the Parking Facility shall be at Tenant’s sole risk, and Landlord shall have no liability for any personal injury or damage to or theft of any vehicles or ether property occurring in the Parking Facility or otherwise in connection with any use of the Parking Facility by Tenant, its employees or invitees. Landlord may alter the size, configuration, design, layout or any other aspect of the Parking Facility without abatement of Rent or liability to Tenant provided that such alteration does not materially impair Tenant’s rights under this Section 24. In addition, for purposes of facilitating any such alteration, Landlord may temporarily deny or restrict access to the Parking Facility, without abatement of Rent or liability to Tenant, provided that Landlord uses commercially reasonable efforts to make reasonable substitute parking available to Tenant. Landlord may delegate its responsibilities hereunder to a parking operator, in which case (i) such parking operator shall have all the rights of control reserved herein by Landlord, (ii) Tenant shall enter into a parking agreement with such parking operator, (iii) Tenant shall pay such parking operator, rather than Landlord, any charge established hereunder for the parking spaces, and (iv) Landlord shall have no liability for claims arising through acts or omissions of such parking operator except to the extent caused by Landlord’s negligence or willful misconduct. Tenant’s parking rights under this Section 24 are solely for the benefit of Tenant’s employees and invitees and such rights may not be transferred without Landlord’s prior consent, except pursuant to a Transfer permitted under Section 14.

25.10 Interpretation. As used herein, the capitalized term “Section” relies to a section hereof unless otherwise specifically provided herein. As used in this Lease, the terms “herein,” “hereof” “hereto” and “hereunder” refer to this Lease and the term “include” and its derivatives are not limiting. Any reference herein to “any part” or “any portion” of the Premises, the Property or any other property shall be construed to refer to all or any part of such property. Wherever this Lease requires Landlord to provide a customary service or to act in a reasonable manner (whether in incurring an expense, establishing a rule or regulation, providing an approval or consent, or performing any other act), this Lease shall be deemed also to provide that whether such service is customary or such conduct is reasonable shall be determined by reference to the practices of owners of buildings (“Comparable Buildings”) that (i) are comparable to the Building in size, age, class, quality and location, and (ii) at Landlord’s option, have been, or are being prepared to be, certified under the U.S. Green Building Councils Leadership in Energy and Environmental Design (LEED) rating system or a similar rating system. Tenant and Landlord each waive the benefit of any rule that a written agreement shall be construed against the drafting party.

25.11 Entire Agreement. This Lease sets forth the entity agreement between the parties relating to the subject matter hereof and supersedes any previous agreements (none of which shall be used to interpret this Lease). Tenant acknowledges that in entering into this Lease it has not relied upon any representation, warranty or statement, whether oral or written, not expressly set forth herein. This Lease can be modified only by a written agreement signed by both parties.

25.12 Other. Landlord, at its option, may cure any Default, without waiving any right or remedy or releasing Tenant from any obligation, in which event Tenant shall pay Landlord, upon demand, the cost of such cure. If any provision hereof is void or unenforceable, no other provision shall be affected. Submission of this instrument for examination or signature by Tenant does not constitute an option or offer to lease, and this instrument is not binding until it has been executed and delivered by both parties. If Tenant is comprised of two or more parties, their obligations shall be joint and several. Time is of the essence with respect to the performance of every provision hereof in which time of performance is a factor. So long as Tenant performs its obligations hereunder, Tenant shall have peaceful and quiet possession of the Premises against any party claiming by, through or under Landlord, subject to the terms hereof. Landlord may transfer its interest herein, in which event Landlord shall be released from, Tenant shall look solely to the transferee for the performance of, and the transferee shall be deemed to have assumed, all of Landlord’s obligations arising hereunder after the date of such transfer (including the return of any Security Deposit) and Tenant shall attorn to the transferee. Landlord reserves all rights not expressly granted to Tenant hereunder, including the right to make alternatives to the Project. No rights to any view or to light or air over any property are granted to Tenant hereunder. The expiration or termination hereof shall not relieve either party of any obligation that accrued before, or continues to accrue after, such expiation or termination.

25.13 Fitness Center. Subject to the provisions of this Section 25.13, so long as Tenant is not in Default under this Lease, and provided Tenant’s employees execute Landlord’s standard waiver of liability form and pay the applicable one time or monthly fee, if any, than Tenant’s employees (the “Fitness Center Users”) shall be entitled to use the fitness center (the “Fitness Center”) in the Building. The use of the Fitness Center shall be subject to the reasonable rules and regulations (including rules regarding hours of use) established from time to time by Landlord for the Fitness Center. Landlord and Tenant acknowledge that the use of the Fitness Center by the Fitness Center Users shall be at their own risk and that the terms and provisions of Section 10.1 of this Lease shall apply to Tenant and the Fitness Center User’s use of the Fitness Center. The costs of operating, maintaining and repairing the Fitness Center may be included as part of Expenses. Tenant acknowledges that the provisions of this Section shall not be deemed to be a representation by Landlord that Landlord shall continuously maintain the Fitness Center (or any other fitness facility) throughout the Term of this Lease, and Landlord shall have

the right, at Landlord’s sole discretion, to expand, contract, eliminate or otherwise modify the Fitness Center. No expansion, contraction, elimination or modification of the Fitness Center, and no termination of Tenant’s or the Fitness Center Users’ rights to the Fitness Center shall entitle Tenant to an abatement or reduction in Rent, or constitute a constructive eviction, or result in an event of default by Landlord under this Lease.

25.14 Shower Facility. Subject to the provisions of this Section 25.14, so long as Tenant is not in Default under this Lease, Tenant employees (the “Shower Users”) shall be entitled to use the shower facility (the “Shower Facility”) in the Building. The use of the Shower Facility shall be subject to the reasonable rules and regulations (including rules regarding hours of use) established from time to time by Landlord for the Shower Facility. Landlord and Tenant acknowledge that the use of the Shower Facility by the Shower Users shall be at their own risk and that the terms and provisions of Section 10.1 of this Lease shall apply to Tenant and the Shower User’s use of the Shower Facility. The costs of operating, maintaining and repairing the Shower Facility shall be included as part of Expenses. Tenant acknowledges that the provisions of this Section shall not be deemed to be a representation by Landlord that Landlord shall continuously maintain the Shower Facility throughout the Term, and Landlord shall have the right, at Landlord’s sole discretion, to expand, contract, eliminate or otherwise modify the Shower Facility. No expansion, contraction, elimination or modification of the Shower Facility, and no termination of Tenant’s or the Shower User’s rights to the Shower Facility shall entitle Tenant to an abatement or reduction in Rent, constitute a constructive eviction, or result in an event of default by Landlord under this Lease.

It is the desire and intention of the parties to agree upon a mechanism and procedure under which controversies and disputes arising out of title Lease or related to the Premises will be resolved in a prompt and expeditious manner. Accordingly, except with respect to actions for unlawful or forcible detainer or with respect to the prejudgment remedy of attachment, any action, proceeding or counterclaim brought by either party hereto against the other (and/or against its officers, directors, employees, agents or subsidiaries or affiliated entities) on any matters arising out of or in any way connected with this Lease, Tenant’s use or occupancy of the Premises and/or any claim of injury or damage, whether sounding in contract, tort, or otherwise, shall be hard and resolved by a referee under the provisions of the California Code of Civil Procedure, Sections 638 — 645.1, inclusive (as same may be amended, or any successor statute(s) thereto) (the “Referee Sections”). Any fee to initiate the judicial reference proceedings and all fees charged and costs incurred by the referee shall be paid by the party initiating such procedure (except that if a reporter is requested by either party, then a reporter shall be present at all proceedings where requested and the fees of such reporter – except for copies ordered by the other parties – shall be borne by the party requesting the reporter); provided however, that allocation of the costs and fees, including any initiation fee, of such proceeding shall be ultimately determined in accordance with Section 25.6 of this Lease. The venue of the proceedings shall be in the county in which the Premises is located. Within 10 days of receipt by any party of a request to resolve any dispute or controversy pursuant to this Exhibit E, the parties shall agree upon a single referee who shall try all issues, whether of fact or law, and report a finding and judgment on such issues as required by the Referee Sections. If the parties are unable to agree upon a referee within such 10-day period, then any party may thereafter file a lawsuit in the county in which the Premises is located for the purpose of appointment of a referee under the Referee Sections. If the referee is appointed by the court, the referee shall be a neutral and impartial retired judge with substantial experience in the relevant matters to be determined, from Jams/Endispute, Inc., ADR Services, Inc. or a similar mediation/arbitration entity approved by each party in its sole and absolute discretion. The proposed referee may be challenged by any party for any of the grounds listed in the Referee Sections. The retiree shall have the power to decide all issues of fact and law and report his or her decision on such issues, and to issue all recognized remedies available at law or in equity for any cause of action that is before the referee, including an award of attorneys’ fees and costs in accordance with this Lease. The referee shall not, however, have the power to award punitive damages, nor any other damages that are not permitted by the express provisions of this Lease, and the parties waive any right to recover any such damages. The parties may conduct all discovery as provided in the California Code of Civil Procedure, and the referee shall oversee discovery and may enforce all discovery orders in the same manner as any trial court judge, with rights to regulate discovery and to issue and enforce subpoenas, protective orders and other limitations on discovery available under California Law. The reference proceeding shall be conducted in accordance with California Law (including the rules of evidence), and in all regards, the referee shall follow California Law applicable at the time of the reference proceeding. The parties shall promptly and diligently cooperate with one another and the referee, and shall perform such acts as may be necessary to obtain a prompt and expeditious resolution of the dispute or controversy in accordance with the terms of this Exhibit E. In this regard, the parties agree that the parties and the

Exhibit E

referee shall use best efforts to ensure that (a) discovery be conducted for a period no longer than 6 months from the date the referee is appointed, excluding motions regarding discovery, and (b) a trial date be set within 9 months of the date the referee is appointed. In accordance with Section 644 of the California Code of Civil Procedure, the decision of the referee upon the whole issue must stand as the decision of the court, and upon the filing of the statement of decision with the clerk of the court, or with the judge if there is no clerk, judgment may be entered thereon in the same manner as if the action had been tried by the court. Any decision of the referee and/or judgment or other order entered thereon shall be appealable to the same extent and in the same manner that such decision, judgment, or order would be appealable if rendered by a judge of the superior court in which venue is proper hereunder. The referee shall in his/her statement of decision set forth his/her findings of fact and conclusions of law. The parties intend this general reference agreement to be specifically enforceable in accordance with the Code of Civil Procedure. Nothing in this Exhibit E shall prejudice the right of any party to obtain provisional relief or other equitable remedies from a court of competent jurisdiction as shall otherwise be available under the Code of Civil Procedure and/or applicable court rules.

Tenant, upon the reasonable request by the Security Holder or such successor in interest, shall execute and deliver an instrument or instruments confirming such attornment. Notwithstanding the foregoing, in the event the Security Holder under any Existing Security Agreement or Existing Loan Document shall have entered into a separate subordination, attornment and non-disturbance agreement directly with Tenant governing Tenant’s obligation to attorn to the Security Holder or such successor in interest as lessor, the terms and provisions of such agreement shall supersede the provisions of this Subsection.

Proceeds.

As used herein, “Proceeds” means any compensation, awards, proceeds, damages, claims, insurance recoveries, causes or rights of action (whenever accrued) or payments which Landlord may receive or to which Landlord may

Exhibit F

become entitled with respect to the Property or any part thereof (other than payments received in connection with any liability or loss of rental value or business interruption insurance) in connection with any taking by condemnation or eminent domain (“Taking”) of or any casualty or other damage or injury to, the Property or any part thereof.

Nothing in this Lease shall be deemed to entitle Tenant to receive and retain Proceeds except those that may be specifically awarded to it in condemnation proceedings because of the Taking of its trade fixtures and its leasehold improvements which have not become part of the Property and such business loss as Tenant may specifically and separately establish. Nothing in the preceding sentence shall be deemed to expand any right Tenant may have under this Lease to receive or retain any Proceeds.

Nothing in this Lease shall be deemed to prevent Proceeds from being held and disbursed by any Security Holder under any Existing Loan Documents in accordance with the terms of such Existing Loan Documents. However, it in the event of any casualty or partial Taking, any obligation of Landlord under this Lease to restore the Premises or the Building is materially diminished by the operation of the preceding sentence, then Landlord, as soon as reasonably practicable after the occurrence of such casualty or partial Taking, shall provide written notice to Tenant describing such diminution with reasonably specificity, whereupon, unless Landlord has agreed in writing, in its sole and absolute discretion, to waive such diminution, Tenant, by written notice to Landlord delivered within 10 days after receipt of Landlord’s notice, shall have the right to terminate this Lease effective 10 days after the date of such termination notice.

2.	Extension Option.

2.1

Grant of Option; Conditions. Tenant shall have the right (the “Extension Option”) to extend the Term for one additional period of two (2) years commencing on the day following the Expiration Date and ending on the second anniversary of the Expiration Date (the “Extension Term”), if:

Not less than 9 and not more than 12 full calendar months before the Expiration Date, Tenant delivers written notice to Landlord (the “Extension Notice’) electing to exercise the Extension Option and stating Tenant’s estimate of the Prevailing Market (defined in Section 2.5 below) rate for the Extension Term;

Tenant is not in default under the Lease beyond any applicable one period when Tenant delivers the Extension Notice;

No part of the Premises is sublet (other than to an Affiliate of Tenant) when Tenant delivers the Extension Notice and

The Lease has not been assigned before Tenant delivers the Extension Notice.

2.2

Terms Applicable to Extension Term.

During the Extension Term, (a) the Base Rent rate per rentable square foot shall be equal to the Prevailing Market rate per rentable square foot; (b) Base Rent

Exhibit F

shall increase, if at all, in accordance with the increases assumed in the determination of Prevailing Market rate; and (c) Base Rent shall be payable in monthly installments in accordance with the terms and conditions of the Lease.

During the Extension Term Tenant shall pay Tenant’s Share of Expenses and Taxes for the Premises in accordance with the Lease.

2.3

Procedure for Determining Prevailing Market. Within 30 days after receiving the Extension Notice, Landlord shall give Tenant either (i) written notice (“Landlord’s Binding Notice”) accepting Tenant’s estimate of the Prevailing Market rate for the Extension Term stated in the Extension Notice, or (ii) written notice (“Landlord’s Rejection Notice”) rejecting such estimate and stating Landlord’s estimate of the Prevailing Market rate for the Extension Term. If Landlord gives Tenant a Landlord’s Rejection Notice, Tenant, within 15 days thereafter, shall give Landlord either (i) written notice (“Tenant’s Binding Notice”) accepting Landlord’s estimate of the Prevailing Market rate for the Extension Term stated in such Landlord’s Rejection Notice, or (ii) written notice (“Tenant’s Rejection Notice”) rejecting such estimate. If Tenant gives Landlord a Tenant’s Rejection Notice, Landlord and Tenant shall work together in good faith to agree in writing upon the Prevailing Market rate for the Extension Term. If, within 30 days after delivery of a Tenant’s Rejection Notice, the parties fail to agree in writing upon the Prevailing Market rate, Tenant’s Extension Option shall be of no further force or effect.

2.4

Extension Amendment. If Tenant is entitled to and properly exercises its Extension Option, and if the Prevailing Market rate for the Extension Term is determined in accordance with Section 2.3 above, Landlord, within a reasonable time thereafter, shall prepare and deliver to Tenant an amendment (the “Extension Amendment”) reflecting changes in the Base Rent, the Term, the Expiration Date, and other appropriate terms, and Tenant shall execute and return the Extension Amendment to Landlord within 15 days after receiving it. Notwithstanding the foregoing, upon determination of the Prevailing Market rate for the Extension Term in accordance with Section 2.3 above, an otherwise valid exercise of the Extension Option shall be fully effective whether or not the Extension Amendment is executed.
