Landlord and Tenant are collectively referred to in this Lease as the “Parties”.

2. PREMISES: Landlord hereby leases to Tenant, and Tenant hires from Landlord those certain Premises with the appurtenances, situated in the City of San ▇▇▇▇, County of Santa ▇▇▇▇▇, State of California, commonly known and designated as ▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇. For purposes of this Lease the building (“Building”) is deemed to be 55,116 rentable square feet, including parking for approximately 220 cars as outlined in red on Exhibit “A” and all common area improvements located therein (“Common Area”) including but not limited to parking areas and structures, landscaping, sidewalks, service areas and other common facilities. The Building and Common Area is situated within a project site shared with One additional building owned by Landlord as outlined in Exhibit “B” attached hereto (“Project”). Unless expressly provided otherwise, the term Premises as used herein shall include the Tenant Improvements (defined in Section 5.B) constructed by Tenant pursuant to Section 5.B.

3. USE:

A. Permitted Uses: Tenant shall use the Premises as permitted under applicable zoning laws only for the following purposes and shall not change the use of the Premises without the prior written consent of Landlord: General office and administration, sales, research and development, marketing, light manufacturing, ancillary storage and other incidental uses.

Tenant will not place or permit to be placed upon the Premises any signs, advertisements or notices without the written consent of Landlord as to type, size, design, lettering, coloring and location, which consent will not be unreasonably withheld. Any sign placed on the Premises shall be removed by Tenant, at its sole cost, prior to the Expiration Date or promptly following the earlier termination of the Lease, and Tenant shall repair, at its sole cost, any damage or injury to the Premises caused thereby, and if not so removed, then Landlord may have same so removed at Tenant’s expense. Landlord hereby agrees to allow Tenant to install signage on the Building and monument signage subject to City approval and Landlord’s reasonable approval as set forth above.

Covenants, Conditions and Restrictions: This Lease is subject to the effect of (i) any covenants, conditions, restrictions, easements, mortgages or deeds of trust, ground leases, rights of way of record and any other matters or documents of record; and (ii) any zoning laws of the city, county and state where the Building is situated (collectively referred to herein as “Restrictions”) and Tenant will conform to and will not violate the terms of any such Restrictions.

4. TERM AND RENTAL:

A. Base Monthly Rent: The term (“Lease Term”) shall be for Eighty-Four (84) months, commencing November 1, 2009 (the “Commencement Date”) and ending October 31, 2016, (“Expiration Date”). Notwithstanding the Parties agreement that the Lease Term begins on the Commencement Date, this Lease and all of the obligations of Landlord and Tenant shall be binding and in full force and effect from and after the Effective Date. In addition to all other sums payable by Tenant under this Lease, Tenant shall pay base monthly rent (“Base Monthly Rent”) in accordance with the following schedule:


11/01/09-10/31/10:		$82,674.00 per month
11/01/10-10/31/11:		$85,981.00 per month
11/01/11-10/31/12:		$89,420.00 per month
11/01/12-10/31/13:		$92,997.00 per month
11/01/13-10/31/14:		$96,717.00 per month
11/01/14-10/31/15:		$100,586.00 per month
11/01/15-10/31/16:		$104,609.00 per month

Base Monthly Rent shall be due in advance on or before the first day of each calendar month during the Lease Term. All sums payable by Tenant under this Lease shall be paid to Landlord in lawful money of the United States of America, without offset or deduction and without prior notice or demand, at the address specified in Section 1 of this Lease or at such place or places as may be designated in writing by Landlord during the Lease Term. Base Monthly Rent for any period less than a calendar month shall be a pro rata portion of the monthly installment. Concurrently with Tenant’s execution of this Lease, Tenant shall pay to Landlord the sum of Eighty Two Thousand Six Hundred Seventy Four and 00/100 Dollars ($82,674.00) as a deposit to be applied on the Commencement Date against the Base Monthly Rent due for the first month of the Lease Term.

C. Late Charges: Tenant hereby acknowledges that late payment by Tenant to Landlord of Base Monthly Rent and other sums due hereunder will cause Landlord to incur costs not contemplated by this Lease, the exact amount of which is extremely difficult to ascertain. Such costs include but are not limited to: administrative, processing, accounting, and late charges which may be imposed on Landlord by the terms of any contract, revolving credit, mortgage, or trust deed covering the Premises. Accordingly, if any installment of Base Monthly Rent or other sum due from Tenant shall not be received by Landlord or its designee within five

Page 2

(5) days after the rent is due, Tenant shall pay to Landlord a late charge equal to five (5%) percent of such overdue amount, which late charge shall be due and payable on the same date that the overdue amount was due. Notwithstanding the foregoing, Landlord will not assess a late charge until Landlord has given written notice of such late payment for the first late payment in any twelve (12) month period and after Tenant has not cured such late payment within three (3) days from receipt of such notice. No other notices will be required during the following twelve (12) months for a late charge to be incurred. The parties agree that such late charge represents a fair and reasonable estimate of the costs Landlord will incur by reason of late payment by Tenant, excluding interest and attorneys fees and costs. If any rent or other sum due from Tenant remains delinquent for a period in excess of thirty (30) days then, in addition to such late charge, Tenant shall pay to Landlord interest on any rent that is not paid when due at the Agreed Interest Rate specified in Section 19.J following the date such amount became due until paid. Acceptance by Landlord of such late charge shall not constitute a waiver of Tenant’s default with respect to such overdue amount nor prevent Landlord from exercising any of the other rights and remedies granted hereunder. In the event that a late charge is payable hereunder, whether or not collected, for three (3) consecutive installments of Base Monthly Rent, then the Base Monthly Rent shall automatically become due and payable quarterly in advance, rather than monthly, notwithstanding any provision of this Lease to the contrary.

5. INTENTIONALLY OMITTED.

6. ACCEPTANCE OF POSSESSION AND COVENANTS TO SURRENDER:

A. Delivery and Acceptance: Tenant shall be entitled to continued possession of the Premises following expiration of the sublease between Tenant and Fed-Ex Freight West pursuant to the terms of this Lease. At the expiration of the sublease and on the Commencement Date of this Lease, Tenant shall accept the Premises as being in good condition and repair as set forth in the existing Master Lease between Landlord and Fed-ex Freight West. Tenant shall have no restoration obligations under the sublease and Landlord hereby waives any rights, if any, it has under the sublease.

B. Condition Upon Surrender: Tenant further agrees on the Expiration Date or on the sooner termination of this Lease, to surrender the Premises to Landlord in good condition and repair, normal wear and tear excepted. In this regard, “normal wear and tear” shall be construed to mean wear and tear caused to the Premises by the natural aging process which occurs in spite of prudent application of the best standards for maintenance, repair replacement, and janitorial practices, and does not include items of neglected or deferred maintenance. In any event, Tenant shall cause the following to be done prior to the Expiration Date or sooner termination of this Lease: (i) all interior walls shall be painted or cleaned so that they appear freshly painted, (ii) all tiled floors shall be cleaned and waxed, (iii) all carpets shall be cleaned and shampooed, (iv) all broken, marred, stained or nonconforming acoustical ceiling tiles shall be replaced, (v) all cabling placed above the ceiling by Tenant or Tenant’s contractors shall be removed, (vi) all windows shall be washed; (vii) the HVAC system shall be serviced by a reputable and licensed service firm and left in “good operating condition and repair” as so certified by such firm, (viii) 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. On or before the Expiration Date or sooner termination of this Lease, Tenant shall remove all its personal property and trade fixtures from the Premises. All property and fixtures not so removed shall be deemed as abandoned by Tenant. Tenant shall ascertain from Landlord at least ninety (90) days before the Expiration Date whether Landlord desires to have any Alterations (as defined in Section 7) made by Tenant removed and the Premises or any parts thereof restored to a standard open office plan with materials and finishes consistent with the other open office areas of the Premises, or to cause Tenant to surrender all Alterations in place to Landlord. Tenant may request from Landlord, at the time

Page 3

of seeking consent to any Alterations, whether or not such Alterations shall need to be removed at the end of the Term. Landlord agrees to specifically respond in writing informing Tenant of its removal and restoration requirements with respect to such Alterations. The foregoing shall not apply to Alterations that Landlord has agreed specifically in writing may remain at Lease expiration at time of granting its consent to such Alterations. If Landlord shall so desire, Tenant shall, at Tenant’s sole cost and expense, remove such Alterations as Landlord requires and shall repair and restore said Premises or such parts thereof before the Expiration Date. Such repair and restoration shall include causing the Premises to be brought into compliance with all applicable building codes and laws in effect at the time of the removal to the extent such compliance is necessitated by the repair and restoration work.

C. Failure to Surrender: If the Premises are not surrendered at the Expiration Date or sooner termination of this Lease in the condition required by this Section 6 (acceptance of such condition to be verified by substantial completion of any restoration work but excluding punch-list items), Tenant shall be deemed in a holdover tenancy pursuant to this Section 6.C and Tenant shall indemnify, defend, and hold Landlord harmless against loss or liability resulting from delay by Tenant in so surrendering the Premises including, without limitation, any claims made by any succeeding tenant founded on such delay to the extent Landlord is obligated to pay such claims and costs incurred by Landlord in returning the Premises to the required condition, plus interest at the Agreed Interest Rate. If Tenant, in advance of any holdover, requests in writing that Landlord inform Tenant of any actual or potential loss or liability that Landlord may suffer as a result of Tenant’s holdover, Landlord agrees that it shall respond in writing, within five (5) days and inform Tenant of any actual and/or potential liability that Landlord has actual knowledge of. If Tenant remains in possession of the Premises after the Expiration Date or sooner termination of this Lease without Landlord’s consent, Tenant’s continued possession shall be on the basis of a tenancy at sufferance and Tenant shall pay as rent during the holdover period an amount equal to one hundred fifty percent (150%) of the Base Monthly Rent due in the month preceding the earlier termination or Expiration Date, as applicable, plus all other amounts payable by Tenant under this Lease. Any holding over shall otherwise be on the terms and conditions herein specified, except those provisions relating to the Lease Term and any options to extend or renew, which provisions shall be of no further force and effect. This provision shall survive the termination or expiration of the Lease.

7. ALTERATIONS AND ADDITIONS:

A. Tenant’s Alterations: Tenant shall not make, or suffer to be made, any alteration or addition to the Premises (“Alterations”), or any part thereof, without obtaining Landlord’s prior written consent and delivering to Landlord the proposed architectural and structural plans for all such Alterations at least fifteen (15) days prior to the start of construction. If such Alterations affect the structure of the Building, Tenant additionally agrees to reimburse Landlord its reasonable out-of-pocket costs incurred in reviewing Tenant’s plans. After obtaining Landlord’s consent, which consent shall state, if requested by Tenant, whether or not Landlord will require Tenant to remove such Alteration at the expiration or earlier termination of this Lease, Tenant shall not proceed to make such Alterations until Tenant has obtained all required governmental approvals and permits. Tenant agrees to provide Landlord (i) written notice of the anticipated and actual start-date of the work, (ii) a complete set of half-size (15” X 21”) vellum as-built drawings, and (iii) a certificate of occupancy for the work upon completion of the Alterations. All Alterations shall be constructed by a licensed general contractor in compliance with all applicable building codes and laws including, without limitation, the Americans with Disabilities Act of 1990 as amended from time to time. Upon the Expiration Date, all Alterations, except movable furniture and trade fixtures, shall become a part of the realty and belong to Landlord but shall nevertheless be subject to removal by Tenant as provided in Section 6 above. Alterations which are not deemed as trade fixtures include heating, lighting, electrical systems, air conditioning, walls, carpeting, or any other installation which has become an integral part of the Premises. All Alterations shall be maintained, replaced or repaired by Tenant at its sole cost and expense.

Page 4

Notwithstanding the foregoing, Tenant shall be entitled, without obtaining Landlord’s consent, to make Alterations which do not affect the Building structure or mechanical systems and which do not cost more than Seventy-Five Thousand Dollars ($75,000.00) per Alteration (“Permitted Alterations”) and do not cost more than Two Hundred Fifty Thousand Dollars ($250,000.00) in aggregate; provided, however, that: (i) Tenant shall still be required to comply with all other provisions of this paragraph; and (ii) Landlord may elect to have Tenant remove such Permitted Alterations at the expiration or earlier termination of the Lease, unless Tenant has notified Landlord of such Permitted Alterations prior to commencing construction and received approval from Landlord that such Permitted Alterations will not be required to be removed at the expiration of the Lease.

Landlord agrees that upon expiration or sooner termination of this Lease, Tenant shall not be responsible for the removal of any alterations and/or improvements made to the Premises that were performed in connection with the sublease described in Section 6.A above or made by or on behalf of a prior tenant of the Premises.

B. Free From Liens: Tenant shall keep the Premises free from all liens arising out of work performed, materials furnished, or obligations incurred by Tenant or claimed to have been performed for Tenant. In the event Tenant fails to discharge any such lien within twenty (20) days after receiving notice of the filing, Landlord shall immediately be entitled to discharge the lien at Tenant’s expense and all resulting costs incurred by Landlord, including attorney’s fees shall be due immediately from Tenant as additional rent.

C. Compliance With Governmental Regulations: The term Laws or Governmental Regulations shall include all federal, state, county, city or governmental agency laws, statutes, ordinances, standards, rules, requirements, or orders now in force or hereafter enacted, promulgated, or issued. The term also includes government measures regulating or enforcing public access, traffic mitigation, occupational, health, or safety standards for employers, employees, landlords, or tenants. Tenant, at Tenant’s sole expense will comply with all such Governmental Regulations applicable to the Premises or the Tenant’s use of the Premises and shall make all repairs, replacements, alterations, or improvements necessary to comply with said Governmental Regulations. The judgment of any court of competent jurisdiction or the admission of Tenant in any action or proceeding against Tenant (whether Landlord be a party thereto or not) that Tenant has violated any such law, regulation or other requirement in its use of the Premises shall be conclusive of that fact as between Landlord and Tenant.

8. MAINTENANCE OF PREMISES:

A. Landlord’s Obligations: Landlord at its sole cost and expense, shall maintain in good condition, order, and repair, and replace as and when necessary, the structural components of the Building including the foundation, exterior load bearing walls and roof structure. Landlord shall maintain in good condition, order and repair, the parking lot and all waterscape, landscaping and shrubbery, the cost of which shall be charged to Tenant through the Reimbursable Operating Costs.

B. Tenant’s Obligations: Tenant shall clean, maintain, repair and replace when necessary the Premises and every part thereof through regular inspections and servicing, including but not limited to the following, to the extent Landlord does not elect to maintain the same as Reimbursable Operating Costs (as defined in Section 8.D below): (i) all plumbing and sewage facilities, (ii) all heating ventilating and air conditioning facilities and equipment, (iii) all fixtures, interior walls floors, carpets and ceilings, (iv) all windows, door entrances, plate glass and glazing systems including caulking, and skylights, (v) all electrical facilities and equipment, and (vi) all automatic fire extinguisher equipment, (vii) all elevator

Page 5

equipment, and (viii) the roof membrane system. All wall surfaces and floor tile are to be maintained in an as good a condition as when Tenant took possession free of holes, gouges, or defacements, subject to normal wear and tear. With respect to items (ii) above, Tenant shall provide Landlord a copy of a service contract between Tenant and a licensed service contractor providing for periodic maintenance of all such systems or equipment in conformance with the manufacturer’s recommendations. Tenant shall provide Landlord a copy of such preventive maintenance contracts and paid invoices for the recommended work if requested by Landlord. To the extent that any item in (i) through (vii) above is determined by Landlord to be for the benefit of more than one (1) tenant or occupant of the Building or Project, Landlord shall assume the obligation to clean, maintain, repair and replace the same as Reimbursable Operating Costs (as defined in Section 8.D below) and Tenant shall have no obligation to clean, maintain, repair or replace such item.

C. Landlord and Tenant’s Obligations Regarding Reimbursable Operating Costs: In addition to the direct payment by Tenant of expenses as provided in Sections 8.B, 9, 10 and 11 of this Lease, Tenant agrees to reimburse Landlord for Tenant’s Allocable Share (as defined in Section 8.E below) of Reimbursable Operating Costs (as defined in Section 8.D below) resulting from Landlord payment of expenses related to the Building or Project which are not otherwise paid by Tenant directly. Landlord shall periodically provide Tenant with a written estimate of Reimbursable Operating Costs for the next twelve (12) months and Tenant shall thereafter, until Landlord revises such estimate, pay to Landlord as additional rental, along with its Base Monthly Rent, one twelfth of Tenant’s Allocable Share of the Reimbursable Operating Costs as estimated by Landlord. Within ninety (90) days after the end of each calendar year during the Term Landlord shall deliver to Tenant a statement (“Annual Statement”) in which Landlord shall set forth the actual expenditures for Reimbursable Operating Costs for such calendar year and Tenant’s Allocable Share thereof. The Annual Statement shall be certified by a responsible officer of Landlord to be correct. If the Annual Statement shows that Tenant’s payments of estimated Reimbursable Operating Costs exceeded Tenant’s actual obligation in respect of such calendar year, Landlord shall accompany said Annual Statement with a payment to Tenant of the amount of such excess. If the Annual Statement shows that Tenant’s payments of estimated Reimbursable Operating Costs were less than its actual obligation in respect of such calendar year, Tenant shall pay said difference to Landlord within thirty (30) days of Tenant’s receipt of the Annual Statement.

D. Reimbursable Operating Costs: For purposes of calculating Tenant’s Allocable Share of Building and Project Costs, the term “Reimbursable Operating Costs” is defined as all costs and expenses of the nature hereinafter described which are incurred by Landlord in connection with ownership and operation of the Building or the Project in which the Premises are located, together with such additional facilities as may be determined by Landlord to be reasonably desirable or necessary to the ownership and operation of the Building and/or Project. All costs and expenses shall be determined in accordance with generally accepted accounting principles (“GAAP”) which shall be consistently applied (with accruals appropriate to Landlord’s business). Reimbursable Operating Costs shall include, but not be limited to, the following to the extent the obligation therefor is not that of Tenant under the provisions of Section 8.B above: (i) common area utilities, including water, power, telephone, heating, lighting, air conditioning, ventilating, and Building utilities to the extent not separately metered; (ii) common area maintenance and service agreements for the Building and/or Project and the equipment therein, including without limitation, common area janitorial services, alarm and security services, exterior window cleaning, and maintenance of the sidewalks, landscaping, waterscape, roof membrane, parking areas, driveways, service areas, mechanical rooms, elevators, and the building exterior; (iii) insurance premiums and costs, including without limitation, the premiums and cost of fire, casualty and liability coverage and rental

Page 6

abatement and, if elected by Landlord, earthquake insurance applicable to the Building or Project; (iv) repairs, replacements and general maintenance (excluding repairs and general maintenance paid by proceeds of insurance or by Tenant or other third parties, and repairs or alterations attributable solely to tenants of the Building or Project other than Tenant) and as to capital expenditures they will be amortized as set forth in 8.E. hereafter; (v) all real estate taxes and assessment installments or other impositions or charges which may be levied on the Building or Project, upon the occupancy of the Building or Project and including any substitute or additional charges which may be imposed during, or applicable to the Lease Term including real estate tax increases due to a sale, transfer or other change of ownership of the Building or Project, as such taxes are levied or appear on the City and County tax bills and assessment rolls; and any of items (i) through (x) in Section 8.B to the extent Landlord has elected to assume with respect thereto the obligations for cleaning, maintenance, repair and/or replacement. Landlord shall have no obligation to provide guard services or other security measures for the benefit of the Project. Tenant assumes all responsibility for the protection of Tenant and Tenant’s Agents from acts of third parties; provided, however, that nothing contained herein shall prevent Landlord, at its sole option, from providing security measures for the Project. This is a “Net” Lease, meaning that Base Monthly Rent is paid to Landlord absolutely net of all costs and expenses, except as specifically provided for in this Lease. The provision for payment of Reimbursable Operating Costs by means of monthly payment of Tenant’s Allocable Share of Building and/or Project Costs is intended to pass on to Tenant and reimburse Landlord for all costs of operating and managing the Building and/or Project (which management reimbursement is pursuant to Section 19.N below).

The following shall not be included within Reimbursable Operating Costs: (i) rent paid to any ground Landlord, (ii) the cost of constructing tenant improvements for any other tenant of the Project to the extent they are not beneficial to Tenant; (iii) the cost of special services, goods, or materials provided to any other tenant of the Project; (iv) repairs paid by proceeds of insurance or from funds provided by Tenant or any other tenant of the Project (or where any other tenant of the Project is obligated to make such repairs or pay the cost of same); (v) legal fees, advertising costs, or other related expenses incurred by Landlord in connection with the leasing of space to individual tenants of the Project; (vi) repairs, alterations, additions, improvements, or replacements needed to rectify or correct any defects in the original design, materials, or workmanship of Project or common areas; (vii) damage and repairs necessitated by the gross negligence of Landlord, Landlord’s employees, contractors, or agents; (viii) executive salaries or salaries of service personnel to the extent that such personnel perform services not in connection with the management, operation, repair, or maintenance of the Project; (ix) Landlord’s general overhead expenses not related to the Project; (x) legal fees, accountants’ fees, and other expenses incurred in connection with disputes of tenants or other occupants of the Project or associated with the enforcement of the terms of any leases with tenants or the defense of Landlord’s title to or interest in the Project or any part thereof; (xi) costs incurred due to a violation by Landlord or any other tenant of the Project of the terms and conditions of a lease; (xii) costs of any service provided to Tenant or other occupants of the Project for which Landlord is reimbursed; (xiii) costs and expenses which would be capitalized under generally accepted accounting principles, except as specifically set forth herein; and (xiv) any clean-up of Hazardous Materials not caused by Tenant.

Tenant shall have the right, at Tenant’s sole cost and expense, provided Tenant utilizes a Nationally recognized Certified Public Accountant (the “CPA”), upon at least thirty (30) days prior notice to Landlord at any time during regular business hours, and no more frequently than once per calendar year, to audit Landlord’s records pertaining to Operating Expenses for the immediately previous calendar year only, which shall be maintained in the State of California. Any disputes between Landlord and Tenant concerning Landlord’s accounting of Additional Rent shall be resolved using GAAP. If it is determined from Tenant’s audit of such

Page 7

operating expenses that Tenant was overcharged by more than five percent (5%), such overcharge shall entitle Tenant to credit against its next payment of Reimbursable Operations Costs the amount of the overcharge and the costs associated with the audit (and, if such credit occurs following the expiration of the Term, Landlord shall pay the amount of such credit to Tenant within thirty (30) days after Landlord’s receipt of an invoice from Tenant). If the audit determines that the Tenant was overcharged less than three percent (3%), such overcharge shall entitle Tenant to credit against its next payment of Reimbursable Operations Costs the amount of the overcharge and Tenant shall pay for all costs associated with the audit. If the audit shall determine that Tenant was undercharged for the Reimbursable Operations Costs, Tenant shall within thirty (30) days pay the amount of such undercharge to Landlord and Tenant shall pay for all costs associated with the audit. Permitted Assignees of Tenant may only audit periods for which they occupy the Leased Premises and subtenants of Tenant are not entitled to any audit rights. Tenant agrees to keep all information thereby obtained by Tenant confidential.

E. Capital Improvements. If as a part of Tenant’s fulfillment of its maintenance obligations under this Section 8, a capital improvement or replacement to the Premises is required, which costs in excess of [Ten Thousand Dollars ($10,000.00)], Landlord shall reimburse Tenant for the cost of the replacement less the sum of (i) [Ten Thousand Dollars ($10,000.00)] plus (ii) that portion of the remaining cost equal to the product of such total cost multiplied by a fraction, the numerator of which is the number of years remaining in the Lease Term, the denominator of which is the useful life (in years) of the replacement, as reasonably determined in accordance with generally accepted accounting principles. If the capital improvement is made during the initial Lease Term, Tenant’s share shall initially be based on the initial Lease Term and if Tenant thereafter exercises its renewal option, then upon the commencement of the Option Term (as defined in Section 18.A below), an adjustment shall be made so that during the Option Term Tenant shall reimburse Landlord an amount determined by multiplying the cost of the capital improvement by a fraction, the numerator of which is the sum of the Lease Term remaining at the time the capital expenditure was made and the Option Term and the denominator of which is the useful life of the capital improvement. The determination of what constitutes capital improvements and the useful life applicable thereto whether in paragraph 8.D. or 8.E. hereto, shall be made according to generally accepted accounting principles (“GAAP”), and all costs related to capital improvements shall be amortized over their useful life, provided that capital improvements shall be limited only to those (i) which have the effect of reducing or limiting Reimbursable Operating Costs of the Building or the Project, if such reduction or limitation inures to Tenant’s benefit (but only to the extent and in the amount that such Reimbursable Operating Costs of the Building or the Project are reduced); (ii) which may be required after the date of this Lease under any governmental law or regulation that was not applicable to the Project at the time it was originally constructed; or (iii) which are necessary for repair or replacement of any equipment or improvements needed to operate and/or maintain the Building, the common areas and/or the Project at the same quality levels as prior to the repair or replacement.

F. Tenant’s Allocable Share: For purposes of prorating Reimbursable Operating Costs which Tenant shall pay, Tenant’s Allocable Share of Reimbursable Operating Costs shall be computed by multiplying the Reimbursable Operating Costs by a fraction, the numerator of which is the rentable square footage of the Premises and the denominator of which is either (i) the total rentable square footage of the Building if the service or cost is allocable only to the Building, or (ii) the total square footage of the Project if the service or cost is allocable to the entire Project, or (iii) the total rentable square footage of the premises of those tenants or occupants that Landlord determines to be benefitting from such service or facility. Tenant’s obligation to share in Reimbursable Operating Costs shall be adjusted to reflect the Lease Commencement and Expiration dates and is subject to recalculation in the event of expansion of the Building or Project.

G. Waiver of Liability: Failure by Landlord to perform any defined services, or any cessation thereof, when such failure is caused by accident, breakage, repairs, strikes, lockout or other labor disturbances or labor disputes of any character or by any other cause, similar or dissimilar, shall not render Landlord liable to Tenant in any respect, including damages to either person or property, nor be construed as an eviction of Tenant, nor cause an abatement of rent, nor relieve Tenant from fulfillment of any covenant or agreement hereof. Should any equipment or machinery utilized in supplying the services listed herein break down or for any cause cease to function properly, upon receipt of written notice from Tenant of any deficiency or failure of any services, Landlord shall use reasonable diligence to repair the same promptly, but Tenant shall have no right to terminate this Lease and shall have no claim for rebate of rent or damages on account of any interruptions in service occasioned thereby or resulting therefrom. Tenant waives the provisions of California Civil Code Sections 1941 and 1942 concerning the Landlord’s obligation of tenantability and Tenant’s right to make repairs and deduct the cost of such repairs from the rent. Landlord shall not be liable for a loss of or injury to person or property, however occurring, through or in connection with or incidental to furnishing, or its failure to furnish, any of the foregoing.

9. HAZARD INSURANCE:

A. Tenant’s Use: Tenant shall not use or permit the Premises, or any part thereof, to be used for any purpose other than that for which the Premises are hereby leased; and no use of the Premises shall be made or permitted, nor acts done, which will cause an increase in premiums or a cancellation of any insurance policy covering the Premises or any part thereof, nor shall Tenant sell or permit to be sold, kept, or used in or about the Premises, any article prohibited by the standard form of fire insurance policies. Tenant shall, at its sole cost, comply with all requirements of any insurance company or organization necessary for the maintenance of reasonable fire and public liability insurance covering the Premises and appurtenances.

B. Landlord’s Insurance: Landlord agrees to purchase and keep in force All Risk and fire insurance in an amount equal to the replacement cost of the Building (not including any Alterations paid for by Tenant) as determined by Landlord’s insurance company’s appraisers. In addition, Landlord may elect to purchase insurance coverage for perils including earthquake, flood or terrorist acts, in amounts and with deductibles reasonably determined by Landlord. Landlord may also maintain a policy of (i) commercial general liability insurance insuring Landlord (and such others designated by Landlord) against liability for personal injury, bodily injury, death and damage to property occurring or resulting from an occurrence in, on or about the Premises or Project in an amount as Landlord determines is reasonably necessary for its protection, and (ii) rental loss insurance covering a twelve (12) month period. Tenant agrees to pay Landlord as additional rent, within thirty (30) days after written invoice to Tenant, Tenant’s Allocable Share of the amount of any deductible under such policy, provided that if damage is confined to the Premises, Tenant shall pay the entire property and casualty deductible to Landlord, not including any earthquake or flood insurance deductible. Notwithstanding the foregoing, Tenant’s obligation to pay for the cost of any earthquake insurance premiums shall not exceed the lesser of the actual cost of such premiums or Four Thousand Four Hundred Nine 28/100 Dollars ($4,409.28) per month for the first year of the Lease Term, and (subject to the cap provided for below) such monthly amount shall be increased annually thereafter by the Consumer Price Index. The basis for computing the adjustment shall be the U.S. Department of Labor, Bureau of Labor Statistic’s Consumer Price Index for All Urban Consumers, All Items, 1982-84=100, for the San Francisco-Oakland-San ▇▇▇▇ area (“Index”). The Index most recently published preceding the date on which the entire Premises are delivered to

Page 9

Tenant shall be considered the “Base Index” for the first adjustment. Thereafter, the index most recently published preceding the previous Adjustment Date shall be considered the “Base Index.” If the Index most recently published preceding the Adjustment Date (“Comparison Index”) is greater than the Base Index, the then-payable Base Monthly Rent shall be increased by multiplying the then-payable Base Monthly Rent by a fraction, the numerator of which is the Comparison Index and the denominator of which is the Base Index. Notwithstanding any subsequent actual increase or decrease in the Index, the increase in CPI for any Adjustment Date shall never be more than Four percent (4%) per year compounded annually, and the deductible payable by Tenant for earthquake insurance shall be treated as a Capital Expenditure as defined in Section 8.E. above. It is understood and agreed that Tenant’s obligation under this Section will be prorated to reflect the Lease Commencement and Expiration Dates.

C. Tenant’s Insurance: Tenant agrees, at its sole cost, to insure its personal property, Tenant Improvements (for which it has paid from sources other than the Work Allowance), and Alterations against damage for their full replacement value (without depreciation). Said insurance shall provide All Risk and fire coverage equal to the replacement cost of said property. The property casualty insurance provided by Tenant as required by this paragraph shall be carried in favor of Landlord and Tenant as their respective interests may appear and shall provide that any loss to Tenant Improvements shall be adjusted with and be payable to both Landlord and Tenant. Tenant shall deliver a copy of the policy and renewal certificate to Landlord. Tenant agrees, at its sole cost, and to obtain worker’s compensation and Commercial General Liability insurance for occurrences within the Premises with a combined single limit of not less than Five Million Dollars ($5,000,000.00) Tenant’s liability insurance shall be primary insurance containing a cross-liability endorsement, and shall provide coverage on an “occurrence” rather than on a “claims made” basis. All such insurance shall provide for severability of interests; shall provide that an act or omission of one of the named (additional) insureds shall not reduce or avoid coverage to the other named (additional insureds). Tenant shall name Landlord and Landlord’s lender as an additional insured and shall deliver a copy of the policies and renewal certificates to Landlord. All insurance policies required under this section shall provide for thirty (30) days’ prior written notice to Landlord of any cancellation, termination, or reduction in coverage. Notwithstanding the above, Landlord retains the right to have Tenant provide other forms of insurance which may be reasonably required to cover future risks.

D. Waiver: Landlord and Tenant hereby waive all tort, contract or other rights each may have against the other on account of any loss or damage sustained by Landlord or Tenant, as the case may be, or to the Premises or its contents, which may arise from any risk covered by their respective insurance policies (or which would have been covered had such insurance policies been maintained in accordance with this Lease) as set forth above. The Parties shall each obtain from their respective insurance companies a waiver of any right of subrogation which said insurance company may have against Landlord or Tenant, as the case may be.

10. TAXES: Tenant shall be liable for and shall pay as additional rental, prior to delinquency, all taxes and assessments levied against Tenant’s personal property and trade or business fixtures. All real estate taxes shall be prorated to reflect the Lease Commencement and Expiration Dates. If, at any time during the Lease Term a tax, excise on rents, business license tax or any other tax, however described, is levied or assessed against Landlord as a substitute or addition, in whole or in part, for taxes assessed or imposed on land or Buildings, Tenant shall pay and discharge its pro rata share of such tax or excise on rents or other tax before it becomes delinquent; except that this provision is not intended to cover net income taxes, inheritance, gift or estate tax imposed upon Landlord. In the event that a tax is placed, levied, or assessed against Landlord and the taxing authority takes the position that Tenant cannot pay and discharge its pro rata share of such tax on behalf of Landlord, then at Landlord’s sole election,

Page 10

Landlord may increase the Base Monthly Rent by the exact amount of such tax and Tenant shall pay such increase. If by virtue of any application or proceeding brought by Landlord, there results a reduction in the assessed value of the Premises during the Lease Term, Tenant agrees to pay Landlord a fee consistent with the fees charged by a third party appeal firm for such services. Tenant at its cost shall have the right, at any time, to seek a reduction in the assessed valuation of the Premises or to contest any real property taxes that are to be paid by Tenant. Landlord shall not be required to join in any such proceeding or contest unless the provisions of any law require that the proceeding or contest be brought by or in the name of the owner of the Premises. In such event, Landlord shall join in the proceeding or contest or permit it to be brought in Landlord’s name, provided that Landlord is not required to bear any cost in connection therewith and is reimbursed for any costs related to such participation by Tenant.

11. UTILITIES: Tenant shall pay directly to the providing utility all water, gas, electric, telephone, and other utilities supplied to the Premises. Landlord shall not be liable for loss of or injury to person or property, however occurring, through or in connection with or incidental to furnishing or the utility company’s failure to furnish utilities to the Premises, and in such event Tenant shall not be entitled to abatement or reduction of any portion of Base Monthly Rent or any other amount payable under this Lease.

12. TOXIC WASTE AND ENVIRONMENTAL DAMAGE:

A. Use of Hazardous Material: Without the prior written consent of Landlord, Tenant or Tenant’s agents, employees, contractors, subtenants or invitees (“Tenant’s Agents”) shall not cause or permit any Hazardous Material, as defined below, to be generated, brought onto, used, stored, created, released or disposed of in or about the Premises, except that Tenant may use and store small quantities of common household cleaners and office supplies on the Premises provided such use and storage is in strict compliance with all Environmental Laws, as defined below. As used herein, the term “Hazardous Material” shall mean any substance, material or waste (whether liquid, solid or gaseous), which is a pollutant or contaminant, or which is hazardous, toxic, ignitable, reactive, corrosive, dangerous, harmful or injurious, or which presents a risk to public health or the environment, or which is or may become regulated by or under the authority of any Environmental Laws, as defined below, including, without limitation, asbestos or asbestos containing materials, petroleum products, pesticides, polychlorinated biphenyls, flammable explosives, radioactive materials and urea formaldehyde. As used herein, the term “Environmental Laws” shall mean any present or future federal, state or local law, whether common law, statute, rule, regulation or ordinance, judgment, order, or other governmental restriction, guideline, listing or requirement, relating to the environment or any Hazardous Material, including without limitation, the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, 42 U.S.C. §9601 et seq., the Resource Conservation and Recovery Act of 1976, 42 U.S.C. §6901 et seq., and applicable provisions of the California Health and Safety Code and the California Water Code, all as heretofore or hereafter may be amended from time to time. In order to obtain consent, Tenant shall deliver to Landlord its written proposal describing the Hazardous Material to be brought onto the Premises, measures to be taken for storage and disposal thereof, and safety measures to be employed to prevent pollution or contamination of the air, soil, surface and groundwater. Landlord’s approval may be withheld in its reasonable judgment. In the event Landlord consents to Tenant’s use of Hazardous Materials on the Premises or such consent is not required, Tenant represents and warrants that it shall comply with all Governmental Regulations applicable to Hazardous Material including doing the following: (i) adhere to all reporting and inspection requirements imposed by Federal, State, County or Municipal laws, ordinances or regulations and provide Landlord a copy of any such reports or agency inspections; (ii) obtain and provide Landlord

Page 11

copies of all necessary permits required for the use and handling of Hazardous Material on the Premises; (iii) enforce Hazardous Material handling and disposal practices consistent with industry standards; (iv) surrender the Premises free from any Hazardous Materials arising from Tenant’s generating, bringing, using, storing, creating, releasing, or disposing of Hazardous Material; and (v) properly close the facility with regard to Hazardous Material including the removal or decontamination of any process piping, mechanical ducting, storage tanks, containers, or trenches which have come into contact with Hazardous Material and obtaining a closure certificate from the local administering agency prior to the Expiration Date.

B. Tenant’s Indemnity Regarding Hazardous Material: Tenant shall, at its sole cost and expense and-with counsel reasonably acceptable to Landlord, indemnify, defend and hold harmless Landlord and Landlord’s trustees, shareholders, directors, officers, employees, partners, affiliates, agents, successors and assigns from, and against any and all claims, liabilities, obligations, penalties, fines, actions, costs or expenses incurred or suffered arising from generating, bringing, using, storing, creating, releasing or disposing of Hazardous Material by Tenant or Tenant’s Agents in or about the Premises, or the violation of any Governmental Regulation or Environmental Laws by Tenant or Tenant’s Agents. This indemnification applies whether or not the concentrations of any such Hazardous Material exceed applicable maximum contaminant or action levels or any governmental agency has issued a cleanup order. Tenant’s indemnification, defense, and hold harmless obligations include, without limitation, the following: (i) claims, liabilities, costs or expenses resulting from or based upon administrative, judicial (civil or criminal) or other action, legal or equitable, brought by any private or public person under present or future laws, including Environmental Laws; (ii) claims, liabilities, costs or expenses pertaining to the assessment and identification, monitoring, cleanup, containment, or removal of Hazardous Material from soils, riverbeds or aquifers including the provision of an alternative public drinking water source; (iii) losses attributable to diminution in the value of the Premises or the Building (iv) loss or restriction of use of rentable space in the Building; (v) adverse effect on the marketing of any space in the Building; and (vi) all other liabilities, obligations, penalties, fines, claims, actions (including remedial or enforcement actions of any kind and administrative or judicial proceedings, orders or judgments), damages (including consequential and punitive damages), and costs (including attorney, consultant, and expert fees and expenses) resulting from the release or violation. This Section 12.B shall survive the expiration or termination o this Lease.

C. Notice of Release or Violation: If, during the Lease Term (including any extensions), Tenant becomes aware of (i) any actual or threatened release of a Hazardous Material on, under or about the Premises or (ii) any inquiry, investigation, proceeding, claim, notice or order by any private or public person or entity regarding the presence of Hazardous Material on, under or about the Premises, including alleged violations of Environmental Laws by Tenant or Tenant’s Agents, Tenant shall give Landlord written notice of the release or investigation within five (5) days after learning of it and shall simultaneously and thereafter furnish Landlord with copies of any claims, notices of violation, reports, or other writings received by Tenant concerning the release or investigation. In the event of an actual release of Hazardous Materials, Tenant shall also give Landlord immediate verbal notice of such release.

In the event of any release on or into the Premises or into the soil or ground water under the Premises, the Building or the Project of any Hazardous Materials used, treated, stored or disposed of by Tenant or Tenant’s Agents, Tenant agrees to comply, at its sole cost, with all laws, regulations, ordinances and orders of any federal, state or local agency relating to the monitoring or remediation of such Hazardous Materials. In the event of any such release of Hazardous Materials Tenant shall immediately give verbal and follow-up written notice of the release to Landlord, and Tenant agrees to meet and confer with Landlord and its Lender to attempt to eliminate and mitigate any financial

Page 12

exposure to such Lender and resultant exposure to Landlord under California Code of Civil Procedure Section 736(b) as a result of such release, and promptly to take reasonable monitoring, cleanup and remedial steps given, inter alia, the historical uses to which the Property has and continues to be used, the risks to public health posed by the release, the then available technology and the costs of remediation, cleanup and monitoring, consistent with acceptable customary practices for the type and severity of such contamination and all applicable laws. Nothing in the preceding sentence shall eliminate, modify or reduce the obligation of Tenant under 12.B of this Lease to indemnify, defend and hold Landlord harmless from any claims liabilities, costs or expenses incurred or suffered by Landlord. Tenant shall provide Landlord prompt written notice of Tenant’s monitoring, cleanup and remedial steps.

In the absence of an order of any federal, state or local governmental or quasi-governmental agency relating to the cleanup, remediation or other response action required by applicable law, any dispute arising between Landlord and Tenant concerning Tenant’s obligation to Landlord under this Section 12.C concerning the level, method, and manner of cleanup, remediation or response action required in connection with such a release of Hazardous Materials shall be resolved by mediation and/or arbitration pursuant to this Lease.

D. Remediation Obligations: In the event of any release on, under or about the Premises of any Hazardous Material generated, brought onto, used, stored, created or disposed of by Tenant or Tenant’s Agents, Tenant shall, at its sole cost, promptly take all necessary and appropriate actions, in compliance with applicable Environmental Laws, to remove or remediate such Hazardous Material, whether or not any governmental agency has issued a cleanup order, so as to return the Premises to the condition that existed before the introduction of such Hazardous Material. Tenant shall obtain Landlord’s written consent prior to implementing any proposed removal or remedial action, provided, however, that Tenant shall be entitled to respond immediately to an emergency without first obtaining Landlord’s written consent. Nothing in the preceding sentence shall in any way eliminate, modify or reduce the obligation of Tenant under 12.B of this Lease to indemnify, defend and hold Landlord harmless from any claims, liabilities, costs or expenses incurred or suffered by Landlord.

E. Environmental Monitoring: Landlord and its agents shall have the right to inspect, investigate, sample and monitor the Premises, including any air, soil, water, ground water, or to conduct any other sampling or testing, digging, drilling or analysis, to determine whether Tenant is complying with the terms of this Section 12. If Landlord discovers that Tenant is not in compliance with the terms of this Section 12, any costs incurred by Landlord in determining Tenant’s non-compliance, including attorneys’, consultants’ and experts’ fees, shall be due and payable by Tenant to Landlord within five (5) days following Landlord’s written demand therefor.

F. Landlord Indemnification. As of the Commencement Date of the Sublease, Landlord shall indemnify and hold Tenant harmless from any claims, liabilities, costs or expenses (including, without limitation, all litigation costs, expert witness fees and reasonable attorneys’ fees) incurred or suffered by Tenant related to the removal, investigation, monitoring or remediation of Hazardous Materials which are present as of the date Tenant first occupied the Premises or which come to be present on the Premises as a result of Landlord’s actions after the date Tenant first occupied the Premises. Landlord’s indemnification and hold harmless obligations include, without limitation, (i) claims, liability, costs or expenses resulting from or based upon administrative, judicial (civil or criminal) or other action, legal or equitable, brought by any private or public person under common law or under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (“CERCLA”), the Resource Conservation and Recovery Act of 1980

Page 13

(“RCRA”) or any other Federal, State, County or Municipal law, ordinance or regulation, (ii) claims, liabilities, costs or expenses pertaining to the identification, monitoring, cleanup, containment, or removal of Hazardous Materials from soils, riverbeds or aquifers including the provision of an alternative public drinking water source, and (iii) all costs of defending such claims. In no event shall Landlord be liable for any consequential damages suffered or incurred by Tenant as a result of any such contamination.

13. TENANT’S DEFAULT: The occurrence of any of the following shall constitute a material default and breach of this Lease by Tenant: (i) Tenant’s failure to pay the Base Monthly Rent including additional rent or any other payment due under this Lease by the date such amount is due where such failure continues for three (3) business days after Tenants receipt of Landlord’s notice that Rent was not received, (ii) the abandonment of the Premises by Tenant; (iii) Tenant’s failure to observe and perform any other required provision of this Lease, where such failure continues for thirty (30) days after written notice from Landlord; (iv) Tenant’s making of any general assignment for the benefit of creditors; (v) the filing by or against Tenant of a petition to have Tenant adjudged a bankrupt or of a petition for reorganization or arrangement under any law relating to bankruptcy (unless, in the case of a petition filed against Tenant, the same is dismissed after the filing); (vi) the appointment of a trustee or receiver to take possession of substantially all of Tenant’s assets located at the Premises or of Tenant’s interest in this Lease, where possession is not restored to Tenant within thirty (30) days; (vii) the attachment, execution or other judicial seizure of substantially all of Tenant’s assets located at the Premises or of Tenant’s interest in this Lease, where such seizure is not discharged within thirty (30) days; or (viii) the occurrence of any other event described as a default elsewhere in this Lease or any amendment thereto regardless of whether such event is defined as a material default and breach of this Lease in this Paragraph 13.

A. Remedies: In the event of any such default by Tenant, then in addition to other remedies available to Landlord at law or in equity, Landlord shall have the immediate option to terminate this Lease and all rights of Tenant hereunder by giving written notice of such intention to terminate. In the event Landlord elects to so terminate this Lease, Landlord may recover from Tenant all the following: (i) the worth at time of award of any unpaid rent which had been earned at the time of such termination; (ii) the worth at 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 for the same period that Tenant proves could have been reasonably avoided; (iii) the worth at 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 be reasonably avoided; (iv) any other amount necessary to compensate Landlord for all detriment proximately caused by Tenant’s failure to perform its obligations under this Lease, or which in the ordinary course of things would be likely to result therefrom; including the following: (x) expenses for repairing, altering or remodeling the Premises for purposes of reletting, (y) broker’s fees, advertising costs or other expenses of reletting the Premises, and (z) costs of carrying the Premises such as taxes, insurance premiums, utilities and security precautions; and (v) at Landlord’s election, such other amounts in addition to or in lieu of the foregoing as may be permitted by applicable California law. The term “rent”, as used herein, is defined as the minimum monthly installments of Base Monthly Rent and all other sums required to be paid by Tenant pursuant to this Lease, all such other sums being deemed as additional rent due hereunder. As used in (i) and (ii) above, “worth at the time of award” shall be computed by allowing interest at a rate equal to the discount rate of the Federal Reserve Bank of San Francisco plus five (5%) percent per annum. As used in (iii) above, “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 (1%) percent.

Page 14

B. Right to Re-enter: In the event of any such default by Tenant, Landlord shall have the right, after terminating this Lease, to re-enter the Premises and remove all persons and property. Such property may be removed and stored in a public warehouse or elsewhere at the cost of and for the account of Tenant, and disposed of by Landlord in any manner permitted by law.

C. Continuation of Lease: If Landlord does not elect to terminate this Lease as provided in Section 13.A or 13.B above, then the provisions of California Civil Code Section 1951.4, (Landlord may continue the lease in effect after Tenant’s breach and abandonment and recover rent as it becomes due if Tenant has a right to sublet and assign, subject only to reasonable limitations) as amended from time to time, shall apply and Landlord may from time to time, without terminating this Lease, either recover all rental as it becomes due or relet the Premises or any part thereof for such term or terms and at such rental or rentals and upon such other terms and conditions as Landlord in its sole discretion may deem advisable, with the right to make alterations and repairs to the Premises. In the event that Landlord elects to so relet, rentals received by Landlord from such reletting shall be applied in the following order to: (i) the payment of any indebtedness other than Base Monthly Rent due hereunder from Tenant to Landlord; (ii) the payment of any cost of such reletting; (iii) the payment of the cost of any alterations and repairs to the Premises; and (iv) the payment of Base Monthly Rent and other sums due and unpaid hereunder. The residual rentals, if any, shall be held by Landlord and applied in payment of future Base Monthly Rent as the same may become due and payable hereunder. Landlord shall have the obligation to market the space but shall have no obligation to relet the Premises following a default if Landlord has other comparable available space within the Building or Project. In the event the portion of rentals received from such reletting which is applied to the payment of rent hereunder during any month be less than the rent payable during that month by Tenant hereunder, then Tenant shall pay such deficiency to Landlord immediately upon demand. Such deficiency shall be calculated and paid monthly. Tenant shall also pay to Landlord, as soon as ascertained, any costs and expenses incurred by Landlord in such reletting or in making such alterations and repairs not covered by the rentals received from such reletting.

D. No Termination: Landlord’s re-entry or taking possession of the Premises pursuant to 13.B or 13.C shall not be construed as an election to terminate this Lease unless written notice of such intention is given to Tenant or unless the termination is decreed by a court of competent jurisdiction. Notwithstanding any reletting without termination by Landlord because of any default by Tenant, Landlord may at any time after such reletting elect to terminate this Lease for any such default.

E. Non-Waiver: Landlord may accept Tenant’s payments without waiving any rights under this Lease, including rights under a previously served notice of default. No payment by Tenant or receipt by Landlord of a lesser amount than any installment of rent due shall be deemed as other than payment on account of the amount due. If Landlord accepts payments after serving a notice of default, Landlord may nevertheless commence and pursue an action to enforce rights and remedies under the previously served notice of default without giving Tenant any further notice or demand. Furthermore, the Landlord’s acceptance of rent from the Tenant when the Tenant is holding over without express written consent does not convert Tenant’s Tenancy from a tenancy at sufferance to a month to month tenancy. No waiver of any provision of this Lease shall be implied by any failure of Landlord to enforce any remedy for the violation of that provision, even if that violation continues or is repeated. Any waiver by Landlord of any provision of this Lease must be in writing. Such waiver shall affect only the provision specified and only for the time and in the manner stated in the writing. No delay or omission in the exercise of any right or remedy by Landlord shall impair such right or remedy or be construed as a waiver thereof by Landlord. No act or conduct of Landlord, including, without limitation, the acceptance of keys to the Premises, shall constitute acceptance of the surrender of the Premises by Tenant

Page 15

before the Expiration Date. Only written notice from Landlord to Tenant of acceptance shall constitute such acceptance of surrender of the Premises. Landlord’s consent to or approval of any act by Tenant which requires Landlord’s consent or approvals shall not be deemed to waive or render unnecessary Landlord’s consent to or approval of any subsequent act by Tenant.

F. Performance by Landlord: If Tenant fails to perform any obligation required under this Lease or by law or governmental regulation, Landlord in its sole discretion may, with due notice, without waiving any rights or remedies and without releasing Tenant from its obligations hereunder, perform such obligation, in which event Tenant shall pay Landlord as additional rent all sums paid by Landlord in connection with such substitute performance, including interest at the Agreed Interest Rate (as defined in Section 19.J) within ten (10) days of Landlord’s written notice for such payment.

G. Habitual Default: The provisions of Section 13 notwithstanding, the Parties agree that if Tenant shall have materially defaulted in the performance of any (but not necessarily the same) term or condition of this Lease for three or more times during any twelve (12) month period during the Lease Term, then such conduct shall, at the election of the Landlord, represent a separate event of default which cannot be cured by Tenant. Tenant acknowledges that the purpose of this provision is to prevent repetitive defaults by Tenant, which work a hardship upon Landlord and deprive Landlord of Tenant’s timely performance under this Lease.

14. LANDLORD’S LIABILITY:

A. Limitation on Landlord’s Liability: In the event of Landlord’s failure to perform any of its covenants or agreements under this Lease, Tenant shall give Landlord written notice of such failure and shall give Landlord thirty (30) days to cure or commence to cure such failure prior to any claim for breach or resultant damages, provided, however, that if the nature of the default is such that it cannot reasonably be cured within the 30-day period, Landlord shall not be deemed in default if it commences within such period to cure, and thereafter diligently prosecutes the same to completion. In addition, upon any such failure by Landlord, Tenant shall give notice by registered or certified mail to any person or entity with a security interest in the Premises (“Mortgagee”) that has provided Tenant with notice of its interest in the Premises, and shall provide Mortgagee a reasonable opportunity to cure such failure, including such time to obtain possession of the Premises by power of sale or judicial foreclosure, if such should prove necessary to effectuate a cure. Tenant agrees that each of the Mortgagees to whom this Lease has been assigned is an expressed third-party beneficiary hereof. Tenant waives any right under California Civil Code Section 1950.7 or any other present or future law to the collection of any payment or deposit from Mortgagee or any purchaser at a foreclosure sale of Mortgagee’s interest unless Mortgagee or such purchaser shall have actually received and not refunded the applicable payment or deposit. Tenant further waives any right to terminate this Lease and to vacate the Premises on Landlord’s default under this Lease. Tenant’s sole remedy on Landlord’s default is an action for damages or injunctive or declaratory relief; provided, however, Landlord and its partners, trustees, beneficiaries and employees shall not be liable to Tenant for any consequential damages suffered or incurred by Tenant on account of Landlord’s default including, without limitation, on account of lost profits or the interruption of Tenant’s business. Tenant hereby agrees that Landlord shall not be liable for injury to Tenant’s business or any loss of income therefrom or for damage to the goods, wares, merchandise, or other property of Tenant, Tenant’s employees, invitees, customers, or any other person in or about the Premises or the Project, nor shall Landlord be liable for injury to the person of Tenant, Tenant’s employees, agents, or contractors, whether such damage or injury is caused by or results from fire, steam, electricity, gas, water, or rain, or from the breakage, leakage, obstruction, or other defects of pipes, sprinklers, wires, appliances, plumbing, air conditioning, or lighting fixtures, or from any other cause, whether said damage or injury results from conditions arising upon the Premises or upon other portions of the Project or

Page 16

from other sources or places and regardless of whether the cause of such damage or injury or the means of repairing the same is inaccessible to Tenant. Landlord shall not be liable for any damages arising from any act or neglect or any other tenant, occupant, or user of the Project, nor from the failure of Landlord to enforce the provisions of any other lease of the Project.

B. Limitation on Tenant’s Recourse: If Landlord is a corporation, trust, partnership, joint venture, unincorporated association or other form of business entity, then (i) the obligations of Landlord shall not constitute personal obligations of the officers, directors, trustees, partners, joint venturers, members, owners, stockholders, or other principals or representatives except to the extent of their property interest in the Premises. Tenant shall have recourse only to the interest of Landlord in the Premises for the satisfaction of the obligations of Landlord and shall not have recourse to any other assets of Landlord for the satisfaction of such obligations.

C. Indemnification of Landlord: Except to the extent due to the negligence or willful misconduct of Landlord, as a material part of the consideration rendered to Landlord, Tenant hereby waives all claims against Landlord for damages to goods, wares and merchandise, and all other personal property in, upon or about said Premises and for injuries to persons in or about said Premises, from any cause arising at any time to the fullest extent permitted by law, and Tenant shall indemnify, defend with counsel reasonably acceptable to Landlord and hold Landlord, and their shareholders, directors, officers, trustees, employees, partners, affiliates and agents from any claims, liabilities, costs or expenses incurred or suffered arising from the use or occupancy of the Premises or any part of the Project by Tenant or Tenant’s Agents, the acts or omissions of Tenant or Tenant’s Agents, Tenant’s breach of this Lease, or any damage or injury to person or property from any cause, including but not limited to the use or occupancy of the Premises or any part of the project by Tenant or Tenant’s Agents, the acts or omissions of Tenant or Tenant’s Agents, Tenant’s breach of this Lease or from the failure of Tenant to keep the Premises in good condition and repair as herein provided. Further, in the event Landlord is made party to any litigation due to the acts or omission of Tenant or Tenant’s Agents, Tenant will indemnify, defend (with counsel reasonably acceptable to Landlord) and hold Landlord harmless from any such claim or liability including Landlord’s costs and expenses and reasonable attorney’s fees incurred in defending such claims.

15. DESTRUCTION OF PREMISES:

A. Landlord’s Obligation to Restore: In the event of a destruction of the Premises during the Lease Term Landlord and Tenant, to the extent of Tenant’s Alterations, shall repair the same to a similar condition to that which existed prior to such destruction. Such destruction shall not annul or void this Lease; however, Tenant shall be entitled to a proportionate reduction of Base Monthly Rent while repairs are being made, such proportionate reduction to be based upon the extent to which the destruction and repairs interfere with Tenant’s business in the Premises. In no event shall Landlord be required to replace or restore Alterations or Tenant’s fixtures or personal property. Tenant shall be obligated to replace and restore all Alterations to the extent feasible.

B. Limitations on Landlord’s Restoration Obligation: Notwithstanding the provisions of Section 15.A, Landlord shall have no obligation to repair, or restore the Premises if any of the following occur: (i) if the repairs cannot be made in one hundred eighty (180) days from the date of receipt of all governmental approvals necessary under the laws and regulations of State, Federal, County or Municipal authorities, as reasonably determined by Landlord, (ii) if the holder of the first deed of trust or mortgage encumbering the Building elects not to permit the insurance proceeds payable upon damage or destruction to be used for such repair or restoration (unless Tenant, within 45

Page 17

days after the casualty, agrees in writing to pay all costs associated with rebuilding), (iii) the damage or destruction is not fully covered by the insurance maintained by Landlord (excluding any deductible amounts) unless Tenant, within 45 days after the casualty, agrees in writing to pay all costs associated with rebuilding, (iv) the damage or destruction occurs in the last twenty four (24) months of the Lease Term (unless Tenant agrees to immediately exercise the Option to extend the Lease pursuant to Section 18 below), (v) Tenant is in default pursuant to the provisions of Section 13, or (vi) Tenant has vacated the Premises for more than ninety (90) days immediately prior to the date of destruction. In any such event Landlord may elect either to (i) complete the repair or restoration, or (ii) terminate this Lease by providing Tenant written notice of its election within sixty (60) days following the damage or destruction. If Landlord elects to repair or restore, this Lease shall continue in full force and effect. Tenant shall also have the right to terminate this Lease in the event of item (i) above by providing Landlord with written notice of its election within ten (10) days after Landlord’s notice of the time period required for repair or restoration. Tenant hereby waives the benefits and rights provided to Tenant by the provisions of Civil Code Sections 1932 and 1933.

16. CONDEMNATION: If any part of the Premises shall be taken for any public or quasi-public use, under any statute or by right of eminent domain or private purchase in lieu thereof, and only a part thereof remains which is susceptible of occupation hereunder, this Lease shall, as to the part so taken, terminate as of the day before title vests in the condemnor or purchaser (“Vesting Date”) and Base Monthly Rent payable hereunder shall be adjusted so that Tenant is required to pay for the remainder of the Lease Term only such portion of Base Monthly Rent as the value of the part remaining after such taking bears to the value of the entire Premises prior to such taking. Further, in the event of such partial taking, Landlord shall have the option to terminate this Lease as of the Vesting Date. If all of the Premises or such part thereof be taken so that there does not remain a portion susceptible for occupation hereunder, this Lease shall terminate on the Vesting Date. If part or all of the Premises be taken, all compensation awarded upon such taking shall go to Landlord, and Tenant shall have no claim thereto; except Landlord shall cooperate with Tenant, without cost to Landlord, to recover compensation for damage to or taking of any Alterations, Tenant Improvements paid for by Tenant from sources other than the Work Allowance, or for Tenant’s moving costs. Tenant hereby waives the provisions of California Code of Civil Procedures Section 1265.130 and any other similarly enacted statue, and the provisions of this Section 16 shall govern in the case of a taking.

Notwithstanding anything to the contrary in this Lease, if there is a taking under the power of eminent domain (or a transfer in lieu thereof), Tenant shall have the right to terminate the Lease if there is a taking of more than twenty-five percent (25%) of the Building or more than twenty-five percent (25%) of the parking area. If any part of the Premises is taken and this Lease is not terminated, then Landlord shall, to the extent not prohibited by Law, repair any damage occasioned thereby to the remainder thereof to a condition reasonably suitable for Tenant’s continued operations.

17. ASSIGNMENT OR SUBLEASE:

A. Consent by Landlord: Except as specifically provided in Section 17.E, Tenant may not voluntarily, involuntarily or by operation of law, assign, sell or otherwise transfer all or any part of Tenant’s interest in this Lease or in the Premises, cause or permit any part of the Premises to be sublet, occupied or used by anyone other than Tenant, or permit any person to succeed to any interest in this Lease or the Premises (all of the foregoing being a “Transfer”) without the express written consent of Landlord. In the event Tenant desires to effectuate a Transfer, Tenant shall deliver to Landlord (i) executed counterparts of any agreement and of all ancillary agreements with the proposed transferee, (ii) current financial statements of the transferee covering the preceding three years, (iii) the nature of the proposed transferee’s business to be carried on in the Premises, (iv) a statement outlining all

Page 18

consideration to be given on account of the Transfer, and (v) a current financial statement of Tenant. Landlord may condition its approval of any Transfer on receipt of a certification from both Tenant and the proposed transferee of all consideration to be paid to Tenant in connection with such Transfer. At Landlord’s request, Tenant shall also provide additional information reasonably required by Landlord to determine whether it will consent to the proposed Transfer. Landlord shall have a fifteen (15) business day period following receipt of all the foregoing within which to notify Tenant in writing that Landlord elects to: (i) terminate this Lease if an assignment, or sublease of substantially the entire Premises for substantially the remaining term of the Lease; (ii) permit Tenant to Transfer such space to the named transferee on the terms and conditions set forth in the notice; or (iii) refuse consent. If Landlord should fail to notify Tenant in writing of such election within the 15-day period, Landlord shall be deemed to have elected option (i) above, provided, however, in the case of a deemed election of option (i) above, Tenant may, within ten (10) days rescind its request for consent, and the Lease shall not terminate and shall remain in full force and effect. In the event Landlord elects option (i) above, this Lease shall expire on the date upon which the proposed Transfer was to commence. In the event Landlord does not elect option (i) above, Landlord’s consent to the proposed Transfer shall not be unreasonably withheld, provided and upon the condition that: (i) the proposed transferee is engaged in a business that is limited to the use generally permitted under this Lease which Landlord agrees to reasonably approve a change in the use of the Premises; (ii) the proposed transfer agreement, if it is a sublease, conforms to the requirements of subsection 17.I (Sublease Requirements) or if it is an assignment, is in a form reasonably satisfactory to Landlord; (iii) the proposed Transfer will not result in there being greater than two (2) subtenants or other occupants (not including employees) within the Premises at any time during the Lease Term; (iv) Tenant reimburses Landlord on demand for any reasonable costs that may be incurred by Landlord in connection with said Transfer, including the reasonable costs of making investigations as to the acceptability of the proposed transferee and reasonable legal costs incurred in connection with the granting or denial of any requested consent; and (v) Tenant shall not have advertised or publicized in any way the availability of the Premises without prior notice to Landlord. In the event all or any one of the foregoing conditions are not satisfied (without limiting other factors that may be considered or conditions that may be imposed by Landlord in connection with a requested Transfer), Landlord shall be considered to have acted reasonably if it withholds its consent. Tenant shall not hypothecate, mortgage, pledge or otherwise encumber Tenant’s interest in this Lease or the Premises or otherwise use the Lease as a security device in any manner without the consent of Landlord, (all of the foregoing being an “Hypothecation”) which consent Landlord may withhold in its sole discretion. Tenant shall reimburse Landlord on demand for any reasonable costs that may be incurred by Landlord in connection with an Hypothecation, including legal costs incurred in connection with the granting or denial of any requested consent. Landlord’s consent to one or more Transfers or Hypothecations shall not operate to waive Tenant’s obligation to obtain Landlord’s consent to other Transfers or Hypothecations nor constitute consent to an assignment or other Transfer following foreclosure of any permitted lien, mortgage or other encumbrance. If Tenant is a corporation, limited liability company, unincorporated association, partnership or other legal entity, the sale, assignment, transfer or hypothecation of any stock, membership or other ownership interest in such entity (whether occurring at one time or over a period of time) in the aggregate of more than fifty percent (50%) (determined cumulatively) shall be deemed an assignment of this Lease; in the case of a

Page 19

partnership, any withdrawal or substitution (whether occurring at one time or over a period of time) of any partners owning fifty percent (50%) or more (cumulatively) of the partnership, or the dissolution of the partnership shall be deemed an assignment of this Lease; provided that, subject to Section 17.D below, the foregoing provisions of this sentence shall not apply to a transfer of stock in a corporation whose stock is publicly traded on a public stock exchange. If Tenant is a corporation whose stock is not publicly traded on a public stock exchange, any dissolution, merger, consolidation or reorganization of Tenant shall be deemed a Transfer.

B. Assignment or Subletting Consideration: Landlord and Tenant hereby agree that fifty percent (50%) of any rent or other economic consideration (including without limitation, payments for trade fixtures and personal property in excess of the fair market value thereof, stock, warrants, and options)related to the Premises, less adjustments for operating costs for the sublease Premises in excess of the Base Monthly Rent payable hereunder (after deducting therefrom Reasonable Transfer Costs (defined below)) (i) realized by Tenant in connection with any Transfer by Tenant, and/or (ii) realized by a subtenant or any other person or entity (other than Tenant) (any such subtenant, person or entity being a “Subsequent Transferor”) in connection with a sublease, assignment or other Transfer by such Subsequent Transferor, shall be paid by Tenant to Landlord promptly after such amounts are paid to Tenant or a Subsequent Transferor, regardless of the amount of subrent the Subsequent Transferor pays to Tenant or any prior Subsequent Transferor. As used in this Section 17.B, “Reasonable Transfer Costs” shall mean the following costs, to the extent reasonably incurred in connection with the Transfer in question: (i) advertising costs, brokerage commissions and attorneys fees payable to unaffiliated third parties, and (ii) tenant improvement costs incurred solely in connection with such Transfer. Tenant’s obligation to pay over Landlord’s portion of the consideration constitutes an obligation for additional rent hereunder. The above provisions relating to Landlord’s right to terminate the Lease and relating to the allocation of excess rent are independently negotiated terms of the Lease which constitute a material inducement for the Landlord to enter into the Lease, and are agreed by the Parties to be commercially reasonable. No Transfer by Tenant shall relieve it of any obligation under this Lease. Any Transfer which conflicts with the provisions of this Lease shall be void.

C. No Release: Any Transfer shall be made only if and shall not be effective until the transferee shall execute, acknowledge, and deliver to Landlord an agreement, in form and substance satisfactory to Landlord, whereby the transferee shall assume all the obligations of this Lease on the part of Tenant to be performed or observed to the extent of the interest being transferred and shall be subject to all the covenants, agreements, terms, provisions and conditions in this Lease to the extent applicable to the interest being transferred. Notwithstanding any Transfer and the acceptance of rent or other sums by Landlord from any transferee, Tenant and any guarantor shall remain fully liable for the payment of Base Monthly Rent and additional rent due, and to become due hereunder, for the performance of all the covenants, agreements, terms, provisions and conditions contained in this Lease on the part of Tenant to be performed and for all acts and omissions of any transferee or any other person claiming under or through any transferee that shall be in violation of any of the terms and conditions of this Lease, and any such violation shall be deemed a violation by Tenant. Tenant shall indemnify, defend and hold Landlord harmless from and against all losses, liabilities, damages, costs and expenses (including reasonable attorney fees) resulting from any claims that may be made against Landlord by the proposed transferee or by any real estate brokers or other persons claiming compensation in connection with the proposed Transfer.

Page 20

D. Reorganization of Tenant: Notwithstanding any other provision of this Lease, the provisions of this Paragraph 17.D shall apply if Tenant is a publicly-held corporation and: (i) there is a dissolution, merger, consolidation, or other reorganization of or affecting Tenant, where Tenant is not the surviving corporation, or there is a sale of all or substantially all of the assets of Tenant, or (ii) there is a sale, cancellation, surrender, exchange, conversion or any other transfer of stock involving or consisting of more than fifty percent (50%) of the total combined voting power of all classes of Tenant’s capital stock issued, outstanding and entitled to vote for the election of directors, or there is any merger, consolidation or other reorganization of or affecting Tenant, whether the foregoing occurs in a single transaction or in multiple steps, and after any one or more of such events Tenant’s stock is no longer publicly traded. In a transaction under clause (i), the surviving or acquiring corporation or entity (“Surviving Entity”) shall promptly execute and deliver to Landlord an agreement in form reasonably satisfactory to Landlord under which the Surviving Entity assumes the obligations of Tenant hereunder. In a transaction or series of transactions under clause (ii) of this Paragraph, the entities which as a result of such transaction(s) own a greater than fifty percent (50%) interest in Tenant (including, without limitation as a result of a verse triangular merger or a triangular merger) (collectively the “Acquiring Entity”) shall promptly execute and deliver to Landlord a guaranty of lease in form reasonably satisfactory to Landlord under which the Acquiring Entity guarantees the full payment and performance of the obligations of Tenant under the Lease (“Lease Guaranty”). The foregoing notwithstanding, in the event the Surviving Entity or Acquiring Entity is itself not a publicly-traded corporation, but is instead the subsidiary of a publicly-traded corporation (or a subsidiary of a subsidiary of a publicly-traded corporation, or a subsidiary in a chain of entities in which one or more parent corporations are publicly traded), then each publicly-traded parent corporation in such chain shall be required to execute and deliver to Landlord the Lease Guaranty. In addition, in the event that after such acquisition Tenant no longer prepares audited financial statements, then in addition to the financial statements required to be delivered by Tenant hereunder, the entity required to execute the Lease Guaranty shall provide Landlord its audited financial statements at the times and in the manner required of Tenant hereunder. It is the intent of the parties that after such any transaction or series of transactions described in this Paragraph 17.D above, Landlord shall be entitled to rely on the creditworthiness of publicly-traded corporations and to receive audited financial information from publicly-traded corporations.

E. Permitted Transfers: Notwithstanding anything contained in this Section 17, so long as Tenant otherwise complies with the provisions of this Section 17, Tenant may enter into any of the following Transfers (a “Permitted Transfer”) without Landlord’s prior consent, and Landlord shall not be entitled to terminate the Lease or to receive any part of any subrent resulting therefrom that would otherwise be due pursuant to Sections 17.A and 17.B. Tenant may sublease all or part of the Premises or assign its interest in this Lease to (i) any entity which controls, is controlled by, or is under common control with the original Tenant to this Lease by means of an ownership interest of more than fifty percent (50%); (ii) an entity which results from a merger, consolidation or other reorganization in which Tenant is not the surviving entity, so long as the surviving entity has a net worth at the time of such assignment or sublease that is equal to or greater than the net worth of Tenant immediately prior to such transaction; and (iii) an entity which purchases or otherwise acquires all or substantially all of the assets of Tenant so long as such acquiring entity has a net worth at the time of such assignment or sublease that is equal to or greater than the net worth of Tenant immediately prior to such transaction.

Page 21

F. Effect of Default: In the event of Tenant’s default, Tenant hereby assigns all amounts due to Tenant from any Transfer as security for performance of Tenant’s obligations under this Lease, and Landlord may collect such amounts as Tenant’s Attorney-in-Fact, except that Tenant may collect such amounts unless a default occurs as described in Section 13 above. A termination of the Lease due to Tenant’s default shall not automatically terminate a Transfer then in existence; rather at Landlord’s election (1) such Transfer shall survive the Lease termination, (2) the transferee shall attorn to Landlord, and (3) Landlord shall undertake the obligations of Tenant under the transfer agreement; except that Landlord shall not be liable for prepaid rent, security deposits or other defaults of Tenant to the transferee, or for any acts or omissions of Tenant and Tenant’s Agents.

G. Conveyance by Landlord: In the event of any transfer of Landlord’s interest in this Lease, the Landlord herein named (and in case of any subsequent transfer, the then transferor) shall be automatically freed and relieved from and after the date of such transfer of all liability for the performance of any covenants or obligations on the part of Landlord contained in this Lease thereafter to be performed; provided, however, that any funds in the hands of Landlord or the then transferor at the time of such transfer, in which Tenant has an interest shall be turned over to the transferee and any amount then due and payable to Tenant by Landlord or the then transferor under any provision of this Lease shall be paid to Tenant; and provided, further, that upon any such transfer, the transferee shall be deemed to have assumed, subject to the limitations of this Section 17, all of the agreements, covenants and conditions in this Lease to be performed on the part of Landlord, it being intended hereby that the covenants and obligations contained in this Lease to be performed on the part of Landlord shall, subject as aforesaid, be binding on each Landlord, its successors and assigns, only during its period of ownership.

H. Successors and Assigns: Subject to the provisions this Section 17, the covenants and conditions of this Lease shall apply to and bind the heirs, successors, executors, administrators and assigns of all Parties hereto; and all parties hereto comprising Tenant shall be jointly and severally liable hereunder.

I. Sublease Requirements: If Landlord consents to any sublet of the premises by Tenant to an approved Subtenant (“Subtenant”), every sublet transaction shall be evidenced by a written sublease between Tenant and Subtenant (the “Sublease”). The Sublease shall comply with the following requirements: (i) The form of the Sublease and the terms and conditions thereof shall be subject to Landlord’s approval which shall not be withheld unreasonably; (ii) the Sublease shall provide that it is subject to and shall incorporate by reference all of the terms and conditions of this Lease, except those terms and conditions relating to Rent, Additional Rent, any other amount due under this Lease, and any other terms and conditions that Tenant and Subtenant agree are not to be incorporated into the Sublease, provided Tenant shall remain fully liable under the Lease; (iii) the Sublease shall provide that the Subtenant shall have no right to exercise any option or other right granted to Tenant in this Lease; (iv) The Sublease shall contain a waiver of subrogation against Landlord and shall require Subtenant’s insurance policies to acknowledge such waiver of subrogation; (v) The Sublease shall provide that all requirements of the Lease applicable to subleases shall be applicable to sub-subleases; (v) The Sublease shall require Subtenant, acting through Tenant, to obtain Landlord’s prior written approval, to any alteration to the Premises to the same extent Tenant is required by this Lease to obtain such consent; (vii) The Sublease shall require Subtenant to send Landlord copies of any and all notices concerning the Premises that Subtenant is obligated to provide to Tenant and Tenant to send Landlord copies of any and all notices concerning the Premises that Tenant is obligated to provide to Subtenant; and (viii) The Sublease shall provide that, at Landlord’s option, the Sublease shall not terminate in the event that this Lease terminates and shall require Subtenant to execute an attornment agreement if Landlord, in its sole and absolute discretion, shall elect to have the Sublease continue beyond the date of termination of this Lease.

18. OPTION TO EXTEND THE LEASE TERM:

▇. ▇▇▇▇▇ and Exercise of Option: Landlord grants to Tenant, subject to the terms and conditions set forth in this Section 18.A, Two (2) options (the “Options”) to extend the Lease Term for an additional term (the “Option Term”). Each Option Term shall be for a period of Sixty (60) months and shall be exercised, if at all, by written notice to Landlord no earlier than eighteen (18) months prior to the date the Lease Term would expire but for such exercise but no later than nine (9) months prior to the date the Lease Term would expire but for such exercise (unless such Option is exercised earlier pursuant to Section 15.B. above), time being of the essence for the giving of such notice. If Tenant exercises the Option, all of the terms, covenants and conditions of this Lease shall apply except for the grant of additional Options pursuant to this Section, provided that Base Monthly Rent for the Premises payable by Tenant during the Option Term shall be the greater of (i) the Base Monthly Rent applicable to the period immediately prior to the commencement of the Option Term; or (ii) ninety five percent (95%) of the Fair Market Rental as hereinafter defined. Notwithstanding anything herein to the contrary, if Tenant is in monetary or material non-monetary default under any of the terms, covenants or conditions of this Lease either at the time Tenant exercises the Option or at any time thereafter prior to the commencement date of the Option Term, or (ii) Tenant, and/or a Permitted Transferee does not have sufficient financial worth to undertake the financial obligations of this Lease, then Landlord shall have, in addition to all of Landlord’s other rights and remedies provided in this Lease, the right to terminate the Option upon notice to Tenant, in which event the Lease Term shall not be extended pursuant to this Section 18.A. As used herein, the term “Fair Market Rental” is defined as the rental and all other monetary payments, including any escalations and adjustments thereto (including without limitation Consumer Price Indexing) that Landlord could obtain during the Option Term from a third party desiring to lease the Premises, based upon the (i) current use and other potential uses of the Premises, as determined by the rents then obtainable for new leases of space comparable in age and quality to the Premises in the same real estate submarket as the Building and (ii) the credit standing and financial stature of the Tenant. The appraisers shall be instructed that the foregoing five percent (5.0%) discount is intended to offset comparable rents that include the following costs which Landlord will not incur in the event Tenant exercises its option (i) brokerage commissions, (ii) tenant improvement or relocation allowances, (iii) vacancy costs, or (iv) other concessions or inducements.

B. Determination of Fair Market Rental: If Tenant exercises the Option, Landlord shall send Tenant a notice setting forth the Fair Market Rental for the Option Term within thirty (30) days following the Exercise Date. If Tenant disputes Landlord’s determination of Fair Market Rental for the Option Term, Tenant shall, within thirty (30) days after the date of Landlord’s notice setting forth Fair Market Rental for the Option Term, send to Landlord a notice stating that Tenant either elects to terminate its exercise of the Option, in which event the Option shall lapse and this Lease shall terminate on the Expiration Date, or that Tenant disagrees with Landlord’s determination of Fair Market Rental for the Option Term and elects to resolve the disagreement as provided in Section 18.C below. If Tenant does not send Landlord a notice as provided in the previous sentence, Landlord’s determination of Fair Market Rental shall be the Base Monthly Rent payable by Tenant during the Option Term. If Tenant elects to resolve the disagreement as provided in Section 18.C and such procedures are not concluded prior to the commencement date of the Option Term, Tenant shall pay to Landlord as Base Monthly Rent the Fair Market Rental as determined by Landlord in the manner

Page 23

provided above. If the Fair Market Rental as finally determined pursuant to Section 18.C is greater than Landlord’s determination, Tenant shall pay Landlord the difference between the amount paid by Tenant and the Fair Market Rental as so determined in Section 18.C within thirty (30) days after such determination. If the Fair Market Rental as finally determined in Section 18.C is less than Landlord’s determination, the difference between the amount paid by Tenant and the Fair Market Rental as so determined in Section 18.C shall be credited against the next installments of Base Monthly Rent due from Tenant to Landlord hereunder.

C. Resolution of a Disagreement over the Fair Market Rental: Any disagreement regarding Fair Market Rental shall be resolved as follows:

1. Within thirty (30) days after Tenant’s response to Landlord’s notice setting forth the Fair Market Rental, Landlord and Tenant shall meet at a mutually agreeable time and place, in an attempt to resolve the disagreement.

2. If within the 30-day period referred to above, Landlord and Tenant cannot reach agreement as to Fair Market Rental, each party shall select one appraiser to determine Fair Market Rental. Each such appraiser shall arrive at a determination of Fair Market Rental and submit their conclusions to Landlord and Tenant within thirty (30) days after the expiration of the 30-day consultation period described above.

3. If only one appraisal is submitted within the requisite time period, it shall be deemed as Fair Market Rental. If both appraisals are submitted within such time period and the two appraisals so submitted differ by less than ten percent (10%), the average of the two shall be deemed as Fair Market Rental. If the two appraisals differ by more than 10%, the appraisers shall immediately select a third appraiser who shall, within thirty (30) days after his selection, make and submit to Landlord and Tenant a determination of Fair Market Rental. This third appraisal will then be averaged with the closer of the two previous appraisals and the result shall be Fair Market Rental.

4. All appraisers specified pursuant to this Section shall be members of the American Institute of Real Estate Appraisers with not less than ten (10) years experience appraising office and industrial properties in the Santa ▇▇▇▇▇ Valley. Each party shall pay the cost of the appraiser selected by such party and one-half of the cost of the third appraiser.

D. Personal to Tenant: All Options provided to Tenant in this Lease are personal and granted to Monolithic Power Systems Incorporated and are not exercisable by any third party, except a Permitted Transferee, should Tenant assign or sublet all or a portion of its rights under this Lease, unless Landlord consents to permit exercise of any option by any assignee or subtenant, in Landlord’s sole and absolute discretion. In the event Tenant has multiple options to extend this Lease, a later option to extend the Lease cannot be exercised unless the prior option has been properly exercised.

19. GENERAL PROVISIONS:

A. Attorney’s Fees: In the event a suit or alternative form of dispute resolution is brought for the possession of the Premises, for the recovery of any sum due hereunder, to interpret the Lease, or because of the breach of any other covenant herein; then the losing party shall pay to the prevailing party reasonable attorney’s fees including the expense of expert witnesses, depositions and court testimony as part of its costs which shall be deemed to have accrued on the commencement of such action. The prevailing party shall also be entitled to recover all costs and expenses including reasonable attorney’s fees incurred in enforcing any judgment or award against the other party. The foregoing provision relating to post-judgment costs is severable from all other provisions of this Lease.

Tenant represents and warrants to Landlord that it has dealt with the following broker: ▇▇▇▇▇ Lang LaSalle (Tenant’s Broker) and with no other agent, finder or such other person with respect to this Lease and agrees to indemnify and hold Landlord harmless from any claims, costs, liabilities or causes of action asserted against the Landlord by any broker, agent, finder, or other such person not identified above Tenant’s Broker. The commission to the Tenant’s Broker is pursuant to a separate agreement.

D. Choice of Law: This Lease shall be governed by and construed in accordance with California law. Except as provided in Section 19.E, venue shall be Santa ▇▇▇▇▇ County.

E. Dispute Resolution: Landlord and Tenant and any other party that may become a party to this Lease or be deemed a party to this Lease including any subtenants agree that, except for any claim by Landlord for (i) unlawful detainer, (ii) Tenant’s failure to pay the Base Monthly Rent, or (iii) within the jurisdiction of the small claims court (which small claims court shall be the sole court of competent jurisdiction), any controversy, dispute, or claim of whatever nature arising out of, in connection with or in relation to the interpretation, performance or breach of this Lease, including any claim based on contract, tort, or statute, shall be resolved at the request of any party to this agreement through dispute resolution process administered by J.A.M.S. or another judicial mediation service mutually acceptable to the parties located in Santa ▇▇▇▇▇ County, California. The dispute resolution process shall consist of a final and binding arbitration administered by and in accordance with the then existing rules and practices of J.A.M.S. or other judicial mediation service selected in accordance with the then existing rules and practices of J.A.M.S. or the other judicial and mediation service selected, and judgment upon any award rendered by the arbitrator(s) may be entered by any state or federal court having jurisdiction thereof as provided by California Code of Civil Procedure section 1280 et. seq, as said statutes then appear, including any amendments to said statutes or successors to said statutes or amended statutes, except that in no event shall the parties be entitled to propound interrogatories or request for admissions during the arbitration process.

Landlord: Tenant:

F. Entire Agreement: This Lease and the exhibits attached hereto contain all of the agreements and conditions made between the Parties hereto and may not be modified orally or in any other manner other than by written agreement signed by all parties hereto or their respective successors in interest. This Lease supersedes and revokes all previous negotiations, letters of intent, lease proposals, brochures, agreements, representations, promises, warranties, and understandings, whether oral or in writing, between the parties or their respective representatives or any other person purporting to represent Landlord or Tenant.

G. Entry by Landlord: Upon prior notice to Tenant and subject to Tenant’s reasonable security regulations, Tenant shall permit Landlord and his agents to enter into and upon the Premises at all reasonable times, and without any rent abatement or reduction or any liability to Tenant for any loss of occupation or quiet enjoyment of the Premises thereby occasioned, for the following purposes: (i) inspecting and maintaining the Premises; (ii) making repairs, alterations or additions to the Premises; (iii) erecting additional building(s) and improvements on the land where the Premises are situated or on adjacent land owned by Landlord; (iv) performing any obligations of Landlord under the Lease including remediation of Hazardous Materials if determined to be the responsibility of Landlord, (v) posting and keeping posted thereon notices of non-responsibility for any construction, alteration or repair thereof, as required or permitted by any law, and (vi) showing the Premises to Landlord’s or the Master Landlord’s existing or potential successors, purchaser, tenants and lenders. In the event Tenant has not exercised its Option to Extend, Tenant shall permit Landlord and his agents, at any time within twelve (12) months prior to the Expiration Date (or at any time during the Lease if Tenant is in default beyond all applicable notice and cure periods hereunder), to place upon the Premises “For Lease” signs and exhibit the Premises to real estate brokers and prospective tenants at reasonable hours.

H. Estoppel Certificates: At any time during the Lease Term, Tenant shall, within ten (10) business days following written notice from Landlord, execute and deliver to Landlord a written statement certifying, if true, the following: (i) that this Lease is unmodified and in full force and effect (or, if modified, stating the nature of such modification); (ii) the date to which rent and other charges are paid in advance, if any; (iii) acknowledging that there are not, to Tenant’s knowledge, any uncured defaults on Landlord’s part hereunder (or specifying such defaults if they are claimed); and (iv) such other information as Landlord may reasonably request. Any such statement may be conclusively relied upon by any prospective purchaser or encumbrancer of Landlord’s interest in the Premises. Tenant’s failure to deliver such statement within such time shall be conclusive upon the Tenant that this Lease is in full force and effect without modification, except as may be represented by Landlord, and that there are no uncured defaults in Landlord’s performance. Tenant agrees to provide, within five (5) days of Landlord’s request, Tenant’s most recent three (3) years of audited financial statements for Landlord’s use in financing or sale of the Premises or Landlord’s interest therein.

I. Exhibits: All exhibits referred to are attached to this Lease and incorporated by reference.

J. Interest: All rent due hereunder, if not paid when due, shall bear interest at the rate of the Reference Rate published by Bank of America, San ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, plus two percent (2%) per annum from that date until paid in full (“Agreed Interest Rate”). This provision shall survive the expiration or sooner termination of the Lease. Despite any other provision of this Lease, the total liability for interest payments shall not exceed the limits, if any, imposed by the usury laws of the State of California. Any interest paid in excess of those limits shall be refunded to Tenant by application

of the amount of excess interest paid against any sums outstanding in any order that Landlord requires. If the amount of excess interest paid exceeds the sums outstanding, the portion exceeding those sums shall be refunded in cash to Tenant by Landlord. To ascertain whether any interest payable exceeds the limits imposed, any non-principal payment (including late charges) shall be considered to the extent permitted by law to be an expense or a fee, premium, or penalty rather than interest.

K. Modifications Required by Lender: If any lender of Landlord or ground lessor of the Premises requires a modification of this Lease that will not increase Tenant’s cost or expense or materially or adversely change Tenant’s rights and obligations, this Lease shall be so modified and Tenant shall execute whatever documents are required and deliver them to Landlord within ten (10) days after the request.

L. No Presumption Against Drafter: Landlord and Tenant understand, agree and acknowledge that this Lease has been freely negotiated by both Parties; and that in any controversy, dispute, or contest over the meaning, interpretation, validity, or enforceability of this Lease or any of its terms or conditions, there shall be no inference, presumption, or conclusion drawn whatsoever against either party by virtue of that party having drafted this Lease or any portion thereof.

M. Notices: All notices, demands, requests, or consents required to be given under this Lease shall be sent in writing by U.S. certified mail, return receipt requested, overnight commercial courier, or by personal delivery addressed to the party to be notified at the address for such party specified in Section 1 of this Lease, or to such other place as the party to be notified may from time to time designate by at least fifteen (15) days prior notice to the notifying party. When this Lease requires service of a notice, that notice shall replace rather than supplement any equivalent or similar statutory notice, including any notices required by Code of Civil Procedure Section 1161 or any similar or successor statute. Copies of all notices to Tenant shall be sent to: ▇▇▇▇▇▇▇ & ▇▇▇▇▇▇, Attention ▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇, Esq, ▇▇ ▇. ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇.

N. Property Management: In addition, Tenant agrees to pay Landlord along with the expenses to be reimbursed by Tenant a monthly fee for management services rendered by either Landlord or a third party manager engaged by Landlord (which may be a party affiliated with Landlord), in the amount of three percent (3%) of the Base Monthly Rent.

O. Rent: All monetary sums due from Tenant to Landlord under this Lease, including, without limitation those referred to as “additional rent”, shall be deemed as rent.

P. Representations: Except for the provisions of this Lease, Tenant acknowledges that neither Landlord nor any of its employees or agents have made any agreements, representations, warranties or promises with respect to the Premises or with respect to present or future rents, expenses, operations, tenancies or any other matter. Except as herein expressly set forth herein, Tenant relied on no statement of Landlord or its employees or agents for that purpose.

Q. Rights and Remedies: Subject to Section 14 above, All rights and remedies hereunder are cumulative and not alternative to the extent permitted by law, and are in addition to all other rights and remedies in law and in equity.

R. Severability: If any term or provision of this Lease is held unenforceable or invalid by a court of competent jurisdiction, the remainder of the Lease shall not be invalidated thereby but shall be enforceable in accordance with its terms, omitting the invalid or unenforceable term.

S. Submission of Lease: Submission of this document for examination or signature by the parties does not constitute an option or offer to lease the Premises on the terms in this document or a reservation of the Premises in favor of Tenant. This document is not effective as a lease or otherwise until executed and delivered by both Landlord and Tenant.

T. Subordination: This Lease is subject and subordinate to ground and underlying leases, mortgages and deeds of trust (collectively “Encumbrances”) which may now affect the Premises, to any covenants, conditions or restrictions of record, and to all renewals, modifications, consolidations, replacements and extensions thereof; provided, however, if the holder or holders of any such Encumbrance (“Holder”) require that this Lease be prior and superior thereto, within seven (7) days after written request of Landlord to Tenant, Tenant shall execute, have acknowledged and deliver all documents or instruments, in the form presented to Tenant, which Landlord or Holder deems necessary or desirable for such purposes. Landlord shall have the right to cause this Lease to be and become and remain subject and subordinate to any and all Encumbrances which are now or may hereafter be executed covering the Premises or any renewals, modifications, consolidations, replacements or extensions thereof, for the full amount of all advances made or to be made thereunder and without regard to the time or character of such advances, together with interest thereon and subject to all the terms and provisions thereof; provided only, that in the event of termination of any such lease or upon the foreclosure of any such mortgage or deed of trust, Holder agrees to recognize Tenant’s rights under this Lease as long as Tenant is not then in default and continues to pay Base Monthly Rent and additional rent and observes and performs all required provisions of this Lease. Within ten (10) business days after Landlord’s written request, Tenant shall execute any documents required by Landlord or the Holder to make this Lease subordinate to any lien of the Encumbrance. If Tenant fails to do so, then in addition to such failure constituting a default by Tenant, it shall be deemed that this Lease is so subordinated to such Encumbrance. Notwithstanding anything to the contrary in this Section, Tenant hereby attorns and agrees to attorn to any entity purchasing or otherwise acquiring the Premises at any sale or other proceeding or pursuant to the exercise of any other rights, powers or remedies under such encumbrance.

U. Survival of Indemnities: All indemnification, defense, and hold harmless obligations of Landlord and Tenant under this Lease shall survive the expiration or sooner termination of the Lease.

V. Time: Time is of the essence hereunder.

W. Transportation Demand Management Programs: Should a government agency or municipality require Landlord to institute TDM (Transportation Demand Management) facilities and/or programs, Tenant agrees that the cost of TDM imposed facilities and programs required on the Premises, including but not limited to employee showers, lockers, cafeteria, or lunchroom facilities, shall be paid by Tenant. Further, any ongoing costs or expenses associated with a TDM program which are required for the Premises and not provided by Tenant, such as an on-site TDM coordinator, shall be provided by Landlord with such costs being included as additional rent and reimbursed to Landlord by Tenant within thirty (30) days after demand. If TDM facilities and programs are instituted on a Project wide basis, Tenant shall pay its proportionate share of such costs in accordance with Section 8 above.

X. Waiver of Right to Jury Trial: To the extent then authorized by law as of the time of any actual litigation between them and to the extent not already encompassed within the various agreements to arbitrate otherwise contained herein, and as an alternative to arbitration should arbitration for any reason not be enforced, Landlord and Tenant waive their respective rights to trial by jury of any contract or tort claim, counterclaim, cross-complaint, or cause of action in any action, proceeding, or hearing brought by either party against the other on any matter arising out of or in any way connected with this Lease, the relationship of Landlord and Tenant, or Tenant’s use or occupancy of the Premises, including any claim of injury or damage or the enforcement of any remedy under any current or future law, statute, regulation, code, or ordinance.

Y. Landlord’s Right To Terminate: Notwithstanding the foregoing, commencing May 1, 2010, Landlord shall have an ongoing right to terminate this Lease during the Initial Term and any Extension thereof with at least eighteen (18) months prior written notice to Tenant. Landlord shall not have the right to serve such eighteen (18) month written notice prior to May 1, 2010. Notwithstanding the foregoing, Landlord’s right to terminate under this Section 19.Y shall be suspended during such time as the buildings in the Project are one hundred percent (100%) leased and occupied by tenants who are not in default beyond all applicable notice and cure periods under their respective leases. Provided that Landlord shall have the right to deliver notice prior to such time but in no event prior to May 1, 2010. In the event this Lease is terminated pursuant to this Section 19.Y, notwithstanding anything to the contrary in this Lease, Tenant shall not have the obligation to remove any Alterations or other installations to the Premises performed by or on behalf of Tenant.

Z. Tenant’s Right of First Offer to Lease: Tenant shall have the right of first offer on all commercial space in the adjacent Building in the Project as follows:

Landlord will present to Tenant the terms and conditions on which it is prepared to lease any commercial space in the adjacent Building. Tenant shall have seven (7) calendar days in which to respond as to whether it wants to lease the all or any portion thereof pursuant to those terms and conditions. If Tenant fails to respond or responds that it is not interested then Landlord is free to lease the pre-offered space in the adjacent Building to a third party on similar terms and conditions as were offered to Tenant.

AA. Unimproved Pad: Within one hundred twenty (120) days from the date of execution of this Lease, Landlord agrees to negotiate in good faith with Tenant regarding possible uses for the unimproved pad located adjacent to the Building. In any event, Landlord shall keep the unimproved pad in clean condition free of debris.

BB. Upon no less than eighteen (18) months prior written notice given no earlier than the Commencement Day hereof, Tenant consents to the Landlord’s redevelopment of the balance of the Project, excluding the Premises, as a single family residential development provided: (i) such redevelopment does not interfere with Tenant’s use and enjoyment of the Premises or the conduct of Tenant’s business at the Premises; (ii) such redevelopment does not interfere with Tenant’s ingress and egress to the Premises and that there remains direct access to the Premises from the street; and (iii) in no event shall Tenant’s parking rights be reduced below 3.3 per 1,000 usable square feet of the Premises, which parking shall be adjacent to the Premises and for the exclusive use of Tenant.
