PREMISES

Section 2.01 Demise of Premises

Landlord hereby leases to Tenant and Tenant leases from Landlord for the Lease Term, at the rental, and upon all of the terms and conditions set forth herein, certain premises described in the Summary (“Premises”), which Premises comprise a portion of that certain building described in the Summary (the “Building”) which is one of six (6) current, (but seven (7) planned) free standing, office and research and development project buildings (“Project Buildings”) on real property situated in the City of Sunnyvale, County of Santa Clara, State of California and commonly known as Moffett Towers. The Premises are more particularly described and depicted herein in Exhibit ”A.” Subject to the terms and conditions of this Lease, Landlord reserves the right to access and use the restrooms and janitor, telephone and electrical closets (as well as the space above any dropped ceilings) solely for cabling, wiring, pipes and other Building system elements; provided, however, such reservation shall not reduce the size of the Premises or otherwise materially interfere with Tenant’s use and enjoyment of the Premises and, provided, further, that notwithstanding anything to the contrary contained in this Lease, Tenant shall not be responsible for repairing, maintaining, and replacing any cabling, wiring, pipes and other Building system elements located in such areas not installed therein by Tenant, except, subject to Section 7.06 hereof, to the extent damaged or destroyed by the actions of Tenant or any Tenant Parties. The rentable square footage of the Premises, Building and other Project Buildings (the “Rentable Area”) has been determined and certified by Landlord’s architect by a method described as “dripline,” whereby the measurement encompasses the outermost perimeter of the constructed building, including every projection thereof and all area beneath each such projection, whether or not enclosed, with no deduction for any inward deviation of structure and with the measurement being made floor by floor, but beginning from the top of the building. Subject to Landlord’s reasonable security measures, Applicable Laws, emergencies and Force Majeure events, Landlord acknowledges and agrees that Tenant, its employees, agents, and invitees shall have access to the Premises and the Building twenty-four (24) hours a day, seven (7) days a week.

Section 2.02 Common Area

During the Lease Term, Tenant shall have the non-exclusive right to use those portions of the Common Area which are provided, from time to time, for use in common by Landlord, Tenant and/or other tenants of the Building or Lot 1. In addition, during the Lease Term, Tenant and its employees shall have the non-exclusive right, in common with others, to use the Amenities Parcel (as defined below) and the roadways currently known as 11th Avenue and Enterprise Way, which provide access to the Amenities Parcel. Landlord reserves the right, in its sole discretion, to modify the Common Area (including, without limitation, increasing or changing the size thereof, adding or removing Project structures, facilities or other improvements, or changing the use, configuration and elements thereof), to designate certain areas for the exclusive use of Landlord and/or certain tenants of Lot 1 or the Project, and to close or restrict access of certain areas from time to time for repair, maintenance or construction or to prevent a dedication thereof; provided that (i) Tenant nevertheless shall have direct access to the Premises (including access through the lobby of the Buildings and the elevators of the Building)

and to parking areas serving the Building, (ii) any such modifications, when completed, shall not unreasonably interfere with or restrict Tenant’s access to or possession or use of the Premises or the visibility of Tenant’s signage, and (iii) Landlord shall not grant any tenant of the Building any exclusive right to parking spaces in the structured parking area supporting the Building or in the area in front of the Building unless Landlord grants Tenant the same or equivalent rights. Landlord further reserves the right to establish, repeal and amend from time to time reasonable rules and regulations for the use of the Common Area and to grant easements or other rights to use the Common Area to others; provided, however, that (A) no amendment to the rules and regulations shall (I) unreasonably interfere with or restrict Tenant’s access to or possession or use of the Premises, (II) be binding until Tenant has received at least ten (10) business days’ prior written notice of such rules and regulations, or (III) not apply retroactively; (B) to the extent of any conflict between an express provision of this Lease (other than the attached Rules and Regulations) and such Common Area rules and regulations, this Lease shall control, and (C) any such easements shall not reduce the number of Parking Spaces available for Tenant’s use. The “Common Area” shall consist of (i) Project Common Area, which consists of an athletic facility (the "Athletic Facility") and related landscaping to be available for use by Tenant’s employees (collectively with the Athletic Facility, the “Amenities Parcel”), together with 11th Avenue and Enterprise Way, which provide access thereto, (ii) Lot 1 Common Area, which includes all landscaping, sidewalks, walkways, driveways, curbs, parking lots (including striping), roadways within Lot 1, sprinkler systems, lighting, surface water drainage systems, as well as additional or different facilities as Landlord may from time to time designate or install or make available for the use by Tenant in common with others, and (iii) Building Common Area which includes all lobbies (other than the lobbies on Floors 6, 7, 8 of the Building, to the extent fully leased to Tenant), mechanical areas, stairwells, elevators and elevator shafts, pipe, cabling and wiring shafts, telephone closets, raceways, conduits, fiber vaults, meet-me rooms, pathways, riser spaces together with their enclosing walls, plus, to the extent not leased to an occupant, all entrances, elevator and floor lobbies other than the lobbies on Floors 6, 7, and 8 of the Building, to the extent fully-leased to Tenant), common corridors and hallways, restrooms, janitor closets, telephone closets, electric closets and other public or common areas located in the Building.

Section 2.03 Parking

Throughout the Lease Term, Landlord shall provide Tenant with the number of parking spaces set forth in the Summary on an unreserved, non-designated non-exclusive first come-first serve basis. Except as set forth in the Summary, the parking spaces shall include a mixture of surface and structured parking as determined by Landlord, in its reasonable discretion. Landlord shall have no liability for the use of any such parking spaces by anyone (besides Landlord) other than Tenant or Tenant’s visitors. In the event Landlord is required by any law to limit or control parking at the Building or the Project, whether by validation of parking tickets or any other method of assessment, Tenant, at no cost to it or its employees, customers or invitees, agrees to participate in such validation or assessment program under such reasonable and uniformly-applied rules and regulations as are from time to time established by Landlord. Except as otherwise expressly provided herein, all costs and expenses associated with parking areas serving the Project shall be included in Operating Expenses.

Section 2.04 Construction

(a) Tenant Improvement Allowance

Landlord shall provide to Tenant a Tenant Improvement Allowance of Ten Million Sixteen Thousand Eight Hundred and 00/100 Dollars ($10,016,800) (i.e. $80.00 per square foot of Rentable Area in the Premises) to be used for the Tenant Improvements as set forth in the Work Letter attached as Exhibit C. The Tenant Improvement Allowance shall be reduced by an amount equal to: (i) Tenant’s Building Share of the costs associated with the purchase and installation of the 2000 KW Generator, enclosure and related fuel tank and transfer switch (collectively, the “Generator”), (ii) Tenant’s Building Share of the costs associated with the construction of a shipping/loading area for the Building by Landlord (the “Shipping/Loading Access”) in the approximate location described in Exhibit H, and (iii) Tenant’s Lot 1 Share of the costs associated with Landlord’s construction and installation of parking gates at all entrances/exits to the parking structure known as “Parking Structure 1” (“Parking Structure 1”) located at 1060 Enterprise Way immediately behind the Building.

(b) Additional Tenant Improvement Allowance

In addition to the Tenant Improvement Allowance provided for in Section 2.04(a) above, Landlord shall make available to Tenant, at Tenant’s request (provided that such written request is received by Landlord on or before the Commencement Date), an Additional Tenant Improvement Allowance of up to Ten Dollars ($10.00) per square foot of Rentable Area of the initial Premises only to be used for the Tenant Improvements set forth in the Work Letter attached as Exhibit C. In the event that Tenant elects to utilize all or a portion of the Additional Tenant Improvement Allowance, the amount of such Additional Tenant Improvement Allowance shall be amortized over the first eighty-four (84) months of the initial Term of the Lease at a rate of eight percent (8%) per annum, and Tenant shall pay, together with the monthly installments of Rent due hereunder, such monthly amortized amount as Additional Rent.

(i) Deposit of Letter of Credit Security.

In the event that Tenant elects to use all or a portion of the Additional Tenant Improvement Allowance, Tenant shall deposit with Landlord, at the time such Additional Tenant Improvement Allowance is requested, an unconditional, irrevocable letter of credit (“Letter of Credit”) on a form reasonably acceptable to Landlord and, if required, Landlord’s lender(s), and in favor of Beneficiary, defined below, in the amount of the Additional Tenant Improvement Allowance so utilized by Tenant, plus interest thereon at the rate specified in Section 2.04(b) above (the “Letter of Credit Security”) for the sole and exclusive purpose of securing Tenant’s obligation to repay the Additional Tenant Improvement Allowance as required by Section 2.04(b), above. “Beneficiary,” as used herein refers to either: (x) Landlord as beneficiary, or (y) if required by Landlord’s lender(s), Landlord and Landlord’s lender(s) as co-beneficiaries under the Letter of Credit Security. The Letter of Credit Security shall: (i) be issued by a commercial money center bank reasonably satisfactory to Landlord with retail branches in San Francisco, California (the “Issuer”); (ii) be a standby, at-sight, irrevocable letter

of credit; (iii) be payable to Beneficiary; (iv) permit multiple, partial draws; (v) provide that any draw on the Letter of Credit Security shall be made upon receipt by the Issuer of a sight draft accompanied by a letter from Landlord certifying that Tenant is in default of its obligation to repay the Additional Tenant Improvement Allowance as required by this Lease and all applicable notice and cure period related thereto have expired and, therefore, Landlord is entitled to draw on the Letter of Credit Security in the amount of such draw pursuant to the provisions of this Lease; (vi) provide for automatic annual extensions, without amendment (so-called “evergreen” provision) with a final expiry date no sooner than ninety (90) days after the end of the eighty-fourth (84th) month of the Lease Term; (vii) provide that is governed by the Uniform Customs and Practice for Documentary Credits (1993 revisions) International Chamber of Commerce Publication 500; and (viii) be cancelable if, and only if, Issuer delivers to Beneficiary no less than sixty (60) days advance written notice of Issuer’s intent to cancel. Except for those costs and expenses to be borne by Landlord pursuant to Section 2.04(c)(iv), below, Tenant shall pay all costs, expenses, points and/or fees incurred by Tenant in obtaining the Letter of Credit Security.

(ii) Landlord’s Right to Draw on Letter of Credit Security

The Letter of Credit Security shall be held by Landlord solely as security for the repayment by Tenant of the Additional Tenant Improvement Allowance used by Tenant in accordance with Section 2.04(b) above. Landlord shall have the immediate right to draw upon the Letter of Credit Security, in whole or in part and without prior notice to Tenant, other than as required under this Lease, at any time and from time to time: (1) if Tenant fails to pay any installment of the amortized amount of the Additional Tenant Improvement Allowance when due; provided, however, that such failure to pay shall be subject to the same notice and cure periods applicable to a failure to pay Rent, or (2) if Tenant either files a voluntary bankruptcy petition or an involuntary bankruptcy petition is filed against Tenant by an entity or entities other than Landlord, under 11 U.S.C. §101 et seq., or Tenant executes an assignment for the benefit of creditors. No condition or term of this Lease shall be deemed to render the Letter of Credit Security conditional, thereby justifying the Issuer of the Letter of Credit Security in failing to honor a drawing upon such Letter of Credit in a timely manner. The Letter of Credit Security and its proceeds shall constitute Landlord’s sole and separate property (and not Tenant’s property or, in the event of a bankruptcy filing by or against Tenant, property of Tenant’s bankruptcy estate) and Landlord shall immediately upon any draw (and, except as provided above, without notice to Tenant) apply or offset the proceeds of the Letter of Credit Security against any installment of the amortized amount of the Additional Tenant Improvement Allowance that is not paid when due. If any portion of the Letter of Credit Security is properly drawn upon and applied, Tenant shall, within five (5) business days after written demand therefore, restore the Letter of Credit Security to the then unamortized amount of the Additional Tenant Improvement Allowance; Tenant’s failure to do so shall be a default by Tenant. It is expressly understood that Landlord shall be relying on Issuer rather than Tenant for the timely payment of proceeds under the Letter of Credit Security and the rights of Landlord pursuant to this Section are in addition to any rights which Landlord may have against Tenant pursuant to Article XII below. Landlord agrees that, at Tenant’s written request, at the end of each fiscal quarter, provided that Tenant pays all of the installments of the monthly amortized amount of the Additional Tenant Improvement Allowance due during such fiscal quarter in accordance with this Lease, Landlord will promptly execute and deliver to Tenant, for delivery to the Issuer, a

reduction certificate providing for the reduction of the Letter of Credit Security in an amount equal to the payment(s) made by Tenant during that past fiscal quarter.

(iii) Replacement Letter of Credit Security

If, for any reason whatsoever, the Letter of Credit Security becomes subject to cancellation or expiration during the Lease Term, within forty-five (45) days prior to expiration of the Letter of Credit Security, Tenant shall cause the Issuer or another bank satisfying the conditions of Section 2.04(c)(i) above to issue and deliver to Landlord a Letter of Credit Security to replace the expiring Letter of Credit Security (the “Replacement Letter of Credit Security”). The Replacement Letter of Credit Security shall be in the amount of the then unamortized balance of the Additional Tenant Improvement Allowance. Failure of Tenant to cause the Replacement Letter of Credit Security to be issued forty-five (45) days prior to the then pending expiration or cancellation shall entitle Landlord to fully draw down on the existing Letter of Credit Security and, at Landlord’s election, shall be an event of default under this Lese without any relevant notice and cure period.

(iv) Transfer of Beneficiary

During the Lease Term Landlord may transfer its interest in the Lease or Landlord’s lender may change. Landlord may request a change to Beneficiary under the Letter of Credit Security to the successor of Landlord and/or Landlord’s lender (the “Transferee”). Tenant agrees to cooperate and to cause Issuer, at Landlord’s cost, to timely issue a new Letter of Credit Security on the same terms and conditions as the original Letter of Credit Security, except that the new Letter of Credit Security shall be payable to the Transferee. Landlord shall surrender the existing Letter of Credit Security to Tenant simultaneously with Tenant’s delivery of the new Letter of Credit Security to Transferee.

(v) Return of the Letter of Credit Security

The Letter of Credit Security or any balance thereof shall be returned (without interest) to Tenant (or, at Tenant’s option, to the last assignee of Tenant’s interests hereunder) promptly upon payment of the final monthly installment of the amortized Additional Tenant Improvement Allowance.

(vi) Acknowledgment of Parties

Landlord and Tenant (a) acknowledge and agree that in no event or circumstance shall the Letter of Credit Security or any renewal thereof or substitute therefor or any proceeds thereof be deemed to be or treated as a “security deposit” under any law applicable to security deposits in the commercial context, including, but not limited to Section 1950.7 of the California Civil Code, as such Section now exists or as it may be hereafter amended or succeeded (the “Security Deposit Laws”), (b) acknowledge and agree that the Letter of Credit Security (including any renewal thereof or substitute therefor or any proceeds thereof) is not intended to serve as a security deposit, and the Security Deposit Laws shall have no applicability or relevancy thereto, and (c) waive any and all rights, duties and obligations that any such party may now, or in the future will, have relating to or arising from the Security Deposit Laws.

Tenant hereby waives the provisions of Section 1950.7 of the California Civil Code and all other provisions of law, now or hereafter in effect, which (i) establish the time frame by which a Landlord must refund a security deposit under a lease, and/or (ii) provide that a Landlord may claim from a security deposit only those sums reasonably necessary to remedy defaults in the payment of rent, to repair damage caused by a Tenant or to clean the premises, it being agreed that Landlord may, in addition, claim those sums specified in this Section 4.06 and/or those sums reasonably necessary to compensate Landlord for any loss or damage caused by Tenant’s breach of this Lease, including any damages Landlord suffers following termination of this Lease.

ARTICLE III

TERM

Section 3.01 Lease Term

The term of this Lease (the “Lease Term”) shall commence on the Commencement Date set forth in the Summary (the “Commencement Date”), and shall expire, unless sooner terminated or extended as provided for herein, on the Expiration Date set forth in the Summary (the “Expiration Date”). Within thirty (30) days following the Commencement Date, Landlord and Tenant shall execute and deliver a Memorandum of Commencement of Lease Term substantially in the form attached hereto as Exhibit B as a confirmation of the information set forth therein.

Section 3.02 Option to Extend

(a) Exercise

The Option(s) to Extend set forth in the Basic Lease Information, if any, may be exercised by Tenant, if at all, only by delivery of irrevocable written notice (the “Option Notice”) to Landlord given not more than fourteen (14) months nor less than ten (10) months prior to the end of the initial Lease Term or Extended Term, as relevant; provided, however, if, as of the date of delivery of the Option Notice or any day thereafter on or before the last day of the initial Lease Term or Extended Term, as relevant, Tenant (i) is in material default under this Lease (beyond the expiration of any applicable notice period provided under this Lease), (ii) has assigned this Lease to anyone other than an Affiliate (as defined in Section 11.02 below) or (iii) is currently subletting more than fifty percent (50%) of the Premises to anyone other than an Affiliate, then, at the sole option of Landlord exercisable solely by delivering written notice to Tenant within twenty (20) days of the receipt of the Option Notice, the Option Notice shall be totally ineffective, and this Lease shall expire on the last day of the initial Lease Term or Extended Term, if applicable, if not sooner terminated. Furthermore, it is understood and agreed that the Option(s) to Extend contemplated in this Section 3.02 are personal to the originally named Tenant and any Affiliate (as hereinafter defined) and are not transferable without the prior written consent of Landlord.

(b) Extended Term Rent

In the event Tenant exercises an Option to Extend set forth herein, all the terms and conditions of this Lease shall continue to apply during the applicable Extended Term,

except that the Base Rent payable by Tenant during the Extended Term shall be equal to the greater of: (i) the Base Rent due hereunder with respect to the last month of the initial Lease Term or previous Extended Term, if relevant, and (ii) one hundred percent (100%) of Fair Market Rent (as defined below), as determined pursuant to Section 3.02(c) below. “Fair Market Rent” shall mean the effective rental rate, determined on a per rentable square foot basis, being charged (including periodic adjustments thereto as applicable during the period of the applicable Extended Term, to the extent such adjustments are determined to be part of the Fair Market Rent) in transactions entered into within the twelve (12) month period immediately preceding the Negotiation Period, for comparable space in similar buildings in the vicinity of the Project (i.e., buildings of a similar age and quality considering any recent renovations or modernization), with similar floor plate size and with similar amenities, or, if such comparable space is not available, then making adjustments in the determination of Fair Market Rent to reflect the age, quality, layout and amenities of the Premises and the Project, as contrasted to spaces in other buildings used for comparison purposes, in all instances taking into consideration: size; location; floor level; leasehold improvements or allowances provided or to be provided; lease term; extent of services to be provided; the time that the particular rate under consideration became or is to become effective; and any other relevant terms or conditions applicable to both new and renewing tenants including, without limitation, any free rent or other rental inducements.

(i) Negotiation. If Tenant timely and properly exercises an Option to Extend, then, within the first thirty (30) days following the date of delivery of the Option Notice (the “Negotiation Period”), the parties shall meet in good faith to negotiate the Base Rent for the Premises during the Extended Term. If, during the Negotiation Period, the parties agree on the Base Rent for the Premises during the Extended Term, then such agreed amount shall be the Base Rent payable by Tenant during the Extended Term.

(ii) Arbitration. In the event that the parties are unable to agree on the Base Rent for the Premises within the Negotiation Period, then within ten (10) days after the expiration of the Negotiation Period, each party shall separately designate to the other in writing an appraiser to make this determination. Each appraiser designated shall be a member of the Appraisal Institute and shall have at least ten (10) years experience in appraising commercial real property in Santa Clara County. The failure of either party to appoint an appraiser within the time allowed shall be deemed equivalent to appointing the appraiser appointed by the other party, who shall then determine the Fair Market Rent for the Premises for the Extended Term. Within five (5) business days of their appointment, the two designated appraisers shall jointly designate a third similarly qualified appraiser. Within thirty (30) days after their appointment, each of the two appointed appraisers shall submit to the third appraiser a sealed envelope containing such appointed appraiser’s good faith determination of the Fair Market Rent for the Premises for the Extended Term; concurrently with such delivery, each such appraiser shall deliver a copy of his or her determination to the other appraiser. The third appraiser shall, within ten (10) days following receipt of such submissions, then determine which of the two appraisers’ determinations most closely reflects Fair Market Rent and the chosen appraiser’s determination shall be deemed to be the Fair Market Rent for the Premises during the Extended Term. The third appraiser shall have no rights to adjust, amend or otherwise alter the determinations made

by the appraisers selected by the parties, but must select one or the other of such appraisers’ submissions. The determination by such third appraiser shall be final and binding upon the parties. Said third appraiser shall, upon selecting the determination which most closely resembles Fair Market Rent, concurrently notify both parties hereto in writing. The parties shall share the appraisal expenses equally. If the Extended Term begins prior to the determination of Fair Market Rent, Tenant shall pay monthly installments of Base Rent equal to one hundred three percent (103%) of the monthly installment of Base Rent in effect for the last year of the initial Lease Term. Once a determination is made, any over payment or under payment shall be reimbursed as a credit against, or paid by adding to, the monthly installment of Base Rent next falling due.

Section 3.03 Early Termination Option

(a) Tenant shall have a one-time right to terminate this Lease only as of that last day of the eighty-fourth (84th) month of the Lease Term (the “Early Termination Date”) by providing Landlord with written notice (a “Termination Notice”) of its intent to terminate given at least nine (9) months prior to the Early Termination Date.

(b) If Tenant elects to exercise the right to terminate this Lease in accordance with this Section 3.03, Tenant shall pay a cancellation payment simultaneously with the delivery of the Termination Notice in an amount (the “Termination Fee”) equal to the unamortized portion of (i) the abated Rent during the first six months of the Initial Term, (ii) the Tenant Improvement Allowance or any other tenant improvement allowance provided to Tenant, (iii) the costs incurred by Landlord to complete any tenant improvements (including without limitation architectural and engineering fees, permit fees and other soft costs) which were not included in any other allowance provided to Tenant, and (iv) any leasing commissions paid or incurred by Landlord in connection with this Lease, plus interest on the cumulative sum of the items described in subsections (i) through (iv) herein accruing from the Commencement Date of this Lease until such Termination Fee is paid to Landlord at the rate of eight percent (8%) per annum. The parties agree to compute the Termination Fee and include it as an item in the Memorandum of Commencement of Lease Term upon its execution by Landlord and Tenant

(c) Provided that Tenant pays the Termination Fee, the Lease shall terminate as of the Early Termination Date with the same force and effect as if scheduled to expire according to its terms as of such date, and all terms and provisions of this Lease (including, without limitation, the condition of the Premises upon expiration of the Term and survival of indemnity obligations) shall be applicable thereto. If Tenant fails to timely pay the Termination Fee, Tenant’s exercise of its right to terminate shall be null and void and of no force and effect whatsoever, this Lease shall continue in full force and effect and Tenant shall have no further right to terminate this Lease under this Section 3.03.

(d) Notwithstanding the foregoing, Tenant’s exercise of its rights under this Section 3.03 shall, if Landlord so elects in its absolute discretion, be ineffective in the event that Tenant is in default beyond any applicable notice and cure period of this Lease at the time of delivery of a Termination Notice or upon the Early Termination Date.

Tenant shall pay all Rent in lawful money of the United States of America to Landlord at the notice address stated herein or to such other persons or at such other places as Landlord may designate in writing on or before the due date specified for same without prior demand, set-off or deduction of any nature whatsoever. It is the intention of the parties hereto that this Lease shall not be terminable for any reason by Tenant and that Tenant shall in no event be entitled to any abatement of or reduction in Rent payable under this Lease, except as herein expressly provided in Articles VIII and XIII concerning destruction and condemnation. Any present or future law to the contrary shall not alter this agreement of the parties.

installment of Base Rent (for the purposes of this Section 4.04, the Base Rent for the first six (6) months of the Lease Term shall be deemed to be $306,764.50, notwithstanding any abatement of Base Rent during the Abatement Period pursuant to Section 4.02 above); provided, however, that the Management Fee shall not be due or payable for the first six (6) months of the Lease Term). All of the foregoing payments, together with any and all other amounts (other than Base Rent), whether or not contemplated, payable by Tenant pursuant to the terms of this Lease are referred to herein, collectively, as “Additional Rent, “ and Base Rent and Additional Rent are referred to herein, collectively, as “Rent. “

Notwithstanding anything to the contrary contained herein, “Operating Expenses” shall not include (and Tenant shall have no liability for) any of the following: (i) any expenses incurred by Landlord for the sole benefit of Tenant, which expenses shall be reimbursed in full by Tenant pursuant to the other terms of this Lease (other than through reimbursement of Tenant’s Share of Operating Expenses), (ii) any expenses incurred by Landlord for the sole benefit of one or more other tenants of the Building or the Project, which expenses are in fact reimbursed by such tenant(s) (other than through any operating cost reimbursement provision identical or substantially similar to the provisions set forth in this Lease), (iii) any payments of interest or principal relating to any debt secured by the Building or the Project, except any debt incurred by Landlord for the purpose of financing amounts which would otherwise be included in Operating Expenses hereunder, (iv) Landlord’s non-cash depreciation and amortization of the initial construction of any Common Area improvements; provided that nothing herein shall limit Landlord’s ability to collect the cost of other capitalized items pursuant to the terms of this Lease, (v) the cost of relocating any tenants of Lot 1 or the Project, (vi) the cost of any item for which Landlord is actually reimbursed by insurance, condemnations, refund or rebate (and Landlord agrees to use good faith efforts to collect such amounts), (vii) any expenses for repairs or maintenance to the extent actually recovered under any warranties or guarantees applicable to the Building, Lot 1 or the Project, (viii) any cost of testing, surveying, cleaning up, containing, abating, remedying, removing, encapsulating or handling any Hazardous Materials at, in, or under the Project, (ix) any cost or expense arising from any defaults by Landlord under this Lease or any other lease in Lot 1 or the Project, (x) any property management fees for the Building, Lot 1 or the Project in excess of the Management Fee described in Section 4.04 above, (xi) marketing costs, costs of leasing commissions, attorneys’ fees and other costs and expenses incurred in connection with negotiations or disputes with prospective tenants or other occupants of the Building, Lot 1 or Project; (xii) any cost of repairs or alterations resulting from defects in the initial design and construction of the Building or the Project; (xiii) overhead and profit paid to subsidiaries or affiliates of Landlord for management or other services, to the extent that the costs of such services, supplies or materials if the same were not provided by a subsidiary or affiliate, (xiv) costs of decorating, redecorating, or special cleaning or other services offered to other tenants of the Building, but not to Tenant, (xv) wages, salaries, fees, and fringe benefits paid to executive personnel or officers or partners of Landlord; (xvi) any charge for Landlord’s income taxes, excess profit taxes, franchise taxes, or similar taxes on Landlord’s business; (xvii) the cost of any repair made by Landlord because

Notwithstanding the above, if Tenant's Share of the cost of any particular capital expenditure to the Building or Common Area exceeds Fifty Thousand Dollars ($50,000), then such cost, together with interest thereon at the rate actually charged Landlord by any lender or, if no such interest is relevant, with interest thereon at an interest rate equal to the Agreed Rate (as defined in Section 17.02 below), shall be amortized over its useful life, and the amount includible in Operating Expenses shall be limited to the monthly amortized cost thereof. The determination of what constitutes a capital expenditure and the useful life applicable thereto shall be made by Landlord in its good faith discretion using accounting practices commonly utilized in the commercial real estate industry, consistently applied.

For purposes hereof, “Tenant’s Share” shall mean, as applicable: (i) Tenant’s Project Share (hereinafter defined), (ii) Tenant’s Lot 1 Share (hereinafter defined), or (iii) Tenant’s Building Share (hereinafter defined). “Tenant’s Project Share” shall mean the percentage derived by the quotient of the Rentable Area of the Premises divided by the Rentable Area of Lot 1 or the Project. “Tenant’s Lot 1 Share” shall mean the percentage derived by the quotient of the Rentable Area of the Premises divided by the Rentable Area of Lot 1. “Tenant’s Building Share” shall mean the percentage derived by the quotient of the Rentable Area of the Premises divided by the Rentable Area of the Building. Whenever used in this Lease, the term “Tenant’s Share” shall mean either the Tenant’s Project Share, Tenant’s Lot 1 Share or Tenant’s Building Share, as applicable. Landlord and Tenant acknowledge and agree that: (i) Tenant’s Project Share, Tenant’s Lot 1 Share and Tenant’s Building Share shall be the percentages set forth in the Summary, and (ii) Landlord shall not pass through any cost to Tenant in an amount equal to Tenant’s Project Share unless Landlord incurs such cost with respect to the Project as a whole and charges other tenants of the Project on that same basis; Landlord will not pass through

to Tenant any cost in an amount equal to Tenant’s Lot 1 Share unless Landlord incurs such cost with respect to Lot 1 as a whole and charges other tenants of Lot 1 on that same basis; and Landlord will not pass through to Tenant any cost in an amount equal to Tenant’s Building Share unless Landlord incurs such cost with respect to the Building as a whole and charges other tenants of the Building on that same basis. Notwithstanding the foregoing, Tenant’s Share shall be subject to increase or reduction (in an amount Landlord shall, in good faith, determine), based upon any increase or reduction in the Rentable Area of the Project, Lot 1, the Building, or the Premises. By way of example only, were Landlord to build “Building “D” of the Project and the square footage of Building “D” was 227,614 rentable square feet, then the aggregate rentable square footage of the Project would increase to 1,855,710 and Tenant’s Project Share would decrease to 6.75%.

(d) Payment

Commencing on the Commencement Date, and continuing through the Lease Term, Tenant shall pay, on the first day of each calendar month, monthly installments of Tenant’s Share of Operating Expenses, Tenant’s Share of Insurance Expenses and Tenant’s Share of Real Estate Taxes in amounts set forth in a written estimate by Landlord. Landlord shall have the right to revise its estimate upwards one time during a particular calendar year. Provided that Tenant is afforded at least thirty (30) days prior written notice of such revision, then, commencing with Tenant’s next installment of Base Rent due, Tenant thereafter shall pay such amounts set forth in such revised estimate (which may include an additional monthly amount based upon any shortfall in Landlord’s previous estimate). If Tenant is not provided thirty (30) days’ prior written consent of such revision, then Tenant’s obligation to pay such amount shall commence on the first day of the first calendar month following the expiration of the thirty (30) day notice. (By way of example only, if Landlord notifies Tenant that it has revised its estimated statement of Operating Expenses on August 15, then such revised amount shall first be due on October 1.) Landlord shall furnish to Tenant a statement (hereinafter referred to as “Landlord’s Statement”), within ninety (90) days after the end of each calendar year, which shall set forth the actual amounts of Tenant’s Share of Operating Expenses, Tenant’s Share of Insurance Expenses and Tenant’s Share of Real Estate Taxes for such preceding calendar year. In the event that the actual amounts of Tenant’s Share of Operating Expenses, Tenant’s Share of Insurance Expenses and Tenant’s Share of Real Estate Taxes for such preceding calendar year exceed the estimated amounts paid by Tenant with respect to each of Tenant’s Share during such preceding calendar year, then Tenant shall pay to Landlord, as Additional Rent, the entire amount of such excess within thirty (30) days after receipt of Landlord’s Statement. In the event that the actual amounts of Tenant’s Share of Operating Expenses, Tenant’s Share of Insurance Expenses and Tenant’s Share of Real Estate Taxes for such preceding calendar year are less than the estimated amounts paid by Tenant with respect to each of Tenant’s Shares during such preceding calendar year, then Landlord shall apply such difference as a credit to installments of Rent next falling due (or if the Lease Term has expired or terminated and there remains no money due to Landlord, then Landlord shall remit to Tenant the amount of such difference within thirty (30) days of the expiration or earlier termination of the Lease). Tenant’s Share of Operating Expenses, Tenant’s Share of Insurance Expenses and Tenant’s Share of Real Estate Taxes for the ensuing estimation period shall be adjusted upward or downward based upon Landlord’s Statement.

(e) Limited Abatement of Operating Expenses, Insurance Expenses and Real Estate Taxes

Notwithstanding anything to the contrary contained in this Lease, Landlord hereby waives Tenant’s obligation to pay Tenant’s Share of Operating Expenses, Tenant’s Share of Insurance Expenses and Tenant’s Share of Real Estate Taxes and the Management Fee for the Abatement Period (as defined in Section 4.02 above); provided, however, that Tenant shall be obligated to pay Tenant’s Share of any services that are dependent on occupancy of the Premises (e.g. janitorial services and utilities) provided to the Premises during the Abatement Period.

Section 4.06 Tenant’s Right to Review Supporting Data

(a) Exercise of Right by Tenant

Provided that Tenant has not then received an uncured notice of default under this Lease from Landlord and provided further that Tenant strictly complies with the provisions of this Section 4.06, Tenant shall have the right to reasonably review supporting data for any portion of a Landlord’s Statement that Tenant claims is incorrect. In order for Tenant to exercise its right under this Section 4.06, Tenant shall, within one hundred twenty (120) days after any Landlord’s Statement is received, deliver a written notice to Landlord specifying the portions of such Landlord’s Statement that are claimed to be incorrect, and Tenant shall simultaneously pay to Landlord all amounts due from Tenant to Landlord as specified in such Landlord’s Statement if such amounts have not previously been paid. Except as expressly set forth in Section 4.06(c) below, in no event shall Tenant be entitled to withhold, deduct, or offset any monetary obligation of Tenant to Landlord under this Lease, including, without limitation, Tenant’s obligation to make all Base Rent payments and all payments of Additional Rent pending the completion of, and regardless of the results of, any review under this Section 4.06. The right to review granted to Tenant under this Section 4.06 may only be exercised once for any Landlord’s Statement, and if Tenant fails to meet any of the above conditions as a prerequisite to the exercise of such right, the right of Tenant under this Section 4.06 for a particular Landlord’s Statement shall be deemed waived.

(b) Procedures for Review

Tenant agrees that any review of supporting data under this Section shall occur at such location at which Landlord’s records for the Building, Lot 1 or the Project are then located; provided, however, that Landlord agrees to retain such records in a single location either at the Project or at Landlord’s usual location therefor. Any review to be conducted under this Section 4.06 shall be at the sole expense of Tenant and shall be conducted by a firm of certified public accountants of national or regionally standing on a non-contingency basis; provided, however, that if any such review (as agreed upon by Landlord under Section 4.06(c) below) reveals an overcharge to Tenant in excess of three percent (3%), then Landlord shall reimburse Tenant for Tenant’s out-of-pocket third party costs incurred in connection with Tenant’s review. Tenant acknowledges and agrees that any supporting data reviewed under this Section 4.06 shall constitute confidential information of Landlord, which shall not be disclosed to anyone other than the accountants performing the review and the management of Tenant who receive the results of the review. Except (i) to the extent required by law, (ii) in connection with any legal proceeding concerning this Lease, or (iii) to the extent such information or results are otherwise

publicly available, the disclosure of such information or results of the review to any other person by Tenant shall entitle Landlord to all of its rights and remedies available to Landlord and Tenant at law or in equity, with Tenant agreeing that Landlord shall be entitled to pursue and injunction against Tenant to prevent the disclosure of such information in violation of the terms of this Lease.

Provided Tenant has complied with the provisions of this Section 4.06, if Tenant believes the results of the review of supporting data described in Subsection (b) above have revealed Landlord’s calculation of the disputed portion of Landlord’s Statement to be in error, Tenant shall have fifteen (15) days after the completion of the examination to notify Landlord of same in writing. The alleged error(s) shall be described with particularity in Tenant’s notice, which shall be accompanied by all information supporting Tenant’s allegations. The parties hereto may agree to correct such error(s) (in which case Landlord will provide a revised Landlord’s Statement within fifteen (15) days after Tenant’s notice) or a dispute between the parties may persist. Tenant’s sole and exclusive remedy for resolving any such dispute shall be by binding arbitration. The arbitration shall be administered by the office of JAMS in San Francisco, California, and shall be conducted pursuant to its Streamlined Arbitration Rules and Procedures. The arbitrator’s powers shall be limited to resolving the dispute and awarding costs (including reasonable attorneys’ fees) to the prevailing party.

(d) Effect of Tenant’s Default

In the event that Landlord has, in good faith, provided Tenant with written notice that Tenant is in default of its obligations under this Lease at any time during the pendency of a review of records under this Section 4.06, said right to review shall immediately cease and the matters originally set forth in the Landlord’s Statement shall be deemed to be correct.

ARTICLE V

Section 5.01 Permitted Use and Limitations on Use

The Premises shall be used and occupied only for the permitted use set forth in the Summary and for no other use or purpose whatsoever.

Any other alterations or improvements affecting the Premises and required by Applicable Laws, LEED Certification Requirements or private covenants shall be performed by

Landlord and Tenant shall reimburse Landlord for Tenant's Share of such cost at the same time and in the same as Operating Expenses are paid by Tenant under the terms of this Lease.

(c) By executing this Lease, Tenant acknowledges that it has reviewed and satisfied itself as to its compliance, or intended compliance with the applicable zoning and permit requirements, hazardous materials and waste requirements, and all other statutes, laws, or ordinances relevant to the uses stated in Section 5.01 above or the occupancy of the Premises.

Section 5.05 Rules and Regulations

Landlord may from time to time promulgate reasonable and nondiscriminatory rules and regulations applicable for the care and orderly management of the Premises, Lot 1 or the Project and/or its Common Area. Such rules and regulations shall be binding upon Tenant on the tenth (10th) business day after Tenant receives a written copy thereof, and Tenant agrees to thereafter abide by such rules and regulations. No rules and regulations shall require Tenant to pay additional Rent nor shall any such rules and regulations apply retroactively. A copy of the initial Rules and Regulations is attached hereto as Exhibit G. If there is a conflict between the rules and regulations and any of the provisions of this Lease, the provisions of this Lease shall prevail. If Landlord acts reasonably, in good faith, and uniformly enforces the rules and regulations, then Landlord shall not be responsible for the violation of any such rules and regulations against each of the tenants by any person, including, without limitation, Tenant or its employees, agents, invitees, licensees, guests, visitors or contractors.

Section 6.01 Maintenance of Premises and Building

(a) Throughout the Lease Term, Tenant, at its sole cost and expense, shall keep, maintain, repair and replace the Premises and every part thereof (except as provided in 6.01(b) below, and also except for maintenance, repairs or replacement costs caused solely by an act of negligence or intentional misconduct by Landlord during the Lease Term, subject to Section 7.06 below) and all improvements and appurtenances in the Premises, including, without limitation, all interior walls, all doors and windows, all wall surfaces and floor coverings, all Alterations, additions and improvements installed by or on behalf of Tenant during the Lease Term, sewer, plumbing, electrical, lighting, heating, ventilation and cooling systems, fixtures and equipment exclusively servicing the Premises to the point of connection with the base Building systems, all fire sprinklers, all fire safety and security systems, fixtures and equipment exclusively servicing the Premises, all wiring, and all glazing, in the same good order, condition and repair as they are in on the Delivery Date, or as they may be improved after the Delivery Date, normal wear and tear, casualty, condemnation, obsolescence and Landlord’s obligations hereunder excepted. Notwithstanding the foregoing, if Landlord is responsible for construction of the improvement under the Work Letter, then for the first twelve (12) months of the Lease Term Tenant shall not be responsible for the repair or any latent defects in such improvements that Landlord was required to construct to the extent that such defects existed as of the Commencement Date.

(b) At all times during the Lease Term, Landlord, at its sole cost and expense, shall promptly repair all defects in the exterior walls (including all exterior glass which is damaged by structural defects in such exterior walls) and foundation and all other structural portions of the Premises and the Building. At all times during the Lease Term, Landlord shall maintain, repair and replace the Common Area elements of the Building, those portions of the base Building systems not exclusively servicing the Premises, and the exterior walls, structural walls, supporting pillars, foundations, and structural portions of the roof and roof membrane of the

Building. All costs and expenses incurred by Landlord in connection with the foregoing obligations shall be included in Operating Expenses subject to the terms of Section 4.05(b); provided, however, if such maintenance, repair or replacement is due to the acts, omissions or negligence of Tenant or any Tenant Parties (as defined in Section 7.07 below), then Landlord shall notify Tenant in writing and if Tenant fails to make such repairs within thirty (30) days of its receipt of such notice, then Landlord shall nevertheless make such repairs at Tenant’s expense, and Tenant, within thirty (30) days (or, in the case of emergencies, twenty-four (24) hours after receipt of such notice) after receipt of an invoice and reasonable supporting documentation, shall pay to Landlord all reasonable out-of-pocket costs and expenses of any such repairs, together with accrued interest at the Agreed Rate from the date of Landlord’s payment. Tenant shall give Landlord written notice of any needed repairs which are the obligation of Landlord hereunder; provided, however, that Tenant’s failure to provide such notice shall not be deemed a waiver by Tenant. It shall then be the obligation of Landlord, after receipt of such notice, to perform the same within thirty (30) days (or within twenty-four (24) hours in the event of an emergency) after such notice; provided, however, that if the nature of the repairs is such that more than thirty (30) days are reasonably required for performance, then Landlord shall not be deemed to be in default hereunder if Landlord commences such repairs within said thirty (30) day (or twenty-four (24) hour period in the event of an emergency) period and thereafter diligently completes them and provided further, that for purposes of this sentence “commences” includes material steps taken by Landlord to investigate, design, consult, bid or seek permit or other governmental approval in connection with such repair. Should Landlord default, as provided in Section 12.03 below, in its obligation to make any of the repairs assumed by it hereunder with respect to the Premises or Building and if such repairs shall be reasonably necessary to Tenant’s use and occupancy of the Premises, Tenant shall have the right to perform such repairs, in which event Landlord, within thirty (30) days after written demand accompanied by detailed invoice(s), shall pay to Tenant the reasonable, actual out-of-pocket costs expended by Tenant for such repairs together with accrued interest at the Agreed Rate from the date of Tenant’s payment, provided that nothing herein shall be deemed to create a right of setoff or withholding by Tenant of Base Rent or Additional Rent or any other amounts due herein. Landlord grants Tenant a license, effective during the Lease Term, to enter upon those portions of the Premises and the Building to which access is reasonably necessary for Tenant to take such action. Landlord shall not be liable to Tenant for any damage to person or property as a result of any failure to timely perform any of its obligations with respect to the repair, maintenance or replacement of the Premises, the Building, Lot 1 or the Project or any part thereof, and Tenant’s sole right and remedy (together with its rights under Section 12.03 below) shall be the performance of said repairs by Tenant with the right of reimbursement from Landlord, all in accordance with the terms of this Section 6.01(b). Tenant hereby expressly waives all rights under and benefits of Sections 1941 and 1942 of the California Civil Code or under any law, statute or ordinance on the same subject now or hereafter in effect to make repairs and offset the cost of same against Rent or to withhold or delay any payment of Rent or any other of its obligations hereunder as a result of any default by Landlord under this Section 6.01(b).

(c) Tenant agrees to keep the interior of the Premises clean and in sanitary condition as required by the health, sanitary and police ordinances and regulations of any political subdivision having jurisdiction and to remove all trash and debris which may be found in the Premises. Tenant further agrees to keep the interior surfaces of the Premises, including, without limitation, windows, floors, walls, doors, showcases and fixtures clean and neat in appearance.

Tenant may contract directly with the janitorial company used by Landlord as of the Commencement Date to service the Building in order to provide janitorial services to the Premises, in which case, Landlord shall have no obligation to provide janitorial services to the Premises. No agreement entered into by Tenant and Landlord’s janitorial company shall impose any obligation or additional cost on Landlord or otherwise bind Landlord.

(d) If Tenant refuses or neglects to commence (as defined above) such repairs and/or maintenance for which Tenant is responsible under this Article VI within a thirty (30) day period (or within twenty-four (24) hours in the event of an emergency) after written notice from Landlord and thereafter to diligently prosecute the same to completion, then Landlord, upon at least 24 hours prior written notice (except in an emergency when no such notice shall be required), may enter the Premises and cause such repairs and/or maintenance to be made, and Landlord shall not be responsible to Tenant for any loss or damage occasioned thereby, and Tenant, within thirty (30) days after receipt of an invoice, shall pay to Landlord all reasonable, our-of-pocket third party costs and expenses of any such repairs and/or maintenance, together with accrued interest at the Agreed Rate from the date of Landlord’s payment.

Section 6.02 Maintenance of Common Areas

Landlord’s obligations herein shall be performed in a manner to maintain the Building Common Areas, and the Lot 1 Common Areas in a first class condition at reasonably prudent cost and expense. All costs and expenses incurred by Landlord in connection with the foregoing obligations shall be included in Operating Expenses except as otherwise provided in Section 4.05(b); provided, however, if such maintenance, repair or replacement is due to the acts, omissions or negligence of Tenant or any Tenant Parties, then Landlord shall nevertheless make such repairs at Tenant’s expense, and Tenant, within thirty (30) days after receipt of an invoice, shall pay to Landlord all out-of-pocket costs and expenses of any such repairs, together with accrued interest at the Agreed Rate from the date of Landlord’s payment.

Section 6.03 Alterations, Additions and Improvements

No alterations, additions, or improvements (“Alterations”) shall be made to the Premises by Tenant without the prior written consent of Landlord, which shall not be unreasonably withheld, conditioned or delayed; provided, however, that Tenant, without Landlord’s prior written consent, but upon not less than ten (10) business days prior written notice to Landlord, may make Alterations (including removal and rearrangement of prior Alterations) which (a) do not adversely affect any systems or equipment of the Building, Lot 1 or the Project, (b) do not adversely affect the structural integrity or any structural components of the Building, Lot 1 or the Project, and (c) do not involve the expenditure of more than Seventy-Five Thousand and No/100 Dollars ($75,000.00) in the aggregate during any twelve (12) month period. As a condition to Landlord’s obligation to consider any request for consent hereunder, Tenant hereby agrees to pay Landlord upon demand for the reasonable out-of-pocket third party costs and expenses of consultants, engineers, architects and others for reasonable review of plans and specifications

and for monitoring the construction of any proposed Alterations. Landlord may require Tenant to remove any such Alterations at the expiration or sooner termination of the Lease Term and to restore the Premises to their prior condition pursuant to the terms of Section 17.09 hereof by providing written notice to Tenant at the time Landlord responds to Tenant’s request for Landlord’s consent to the Alteration. If Landlord states in its response that it will not require removal, then Tenant shall not be required to remove the applicable Alterations. All Alterations to be made to the Premises shall be designed by and made under the supervision of a California licensed architect and/or California licensed structural engineer (each of whom has been approved by Landlord, with such approval not being unreasonably withheld, conditioned or delayed) and shall be made in accordance with plans and specifications which have been furnished to and approved by Landlord in writing prior to commencement of work. All Alterations shall be constructed and installed, at the sole cost and expense of Tenant, by California licensed contractors approved by Landlord, in compliance with the terms and conditions of the Work Letter, including but not limited to the “Specifications” and “Requirements” set forth in Schedules One and Two thereof, along with all applicable laws and any relevant LEED Certification Requirements, and in good and workmanlike manner, and shall have been approved in writing by the City of Sunnyvale and any other applicable governmental agencies, to the extent such approval is required. Subject to Landlord’s right to require Tenant to remove Alterations in accordance with this Section 6.03 (in which case Tenant shall retain ownership thereof), all Alterations, including, without limitation, all lighting, electrical, heating, ventilation, air conditioning and full height partitioning, drapery and carpeting installations made by Tenant, together with all property that has become an integral part of the Premises, shall not be deemed trade fixtures and shall become the property of Landlord at the expiration or sooner termination of the Lease. Tenant shall retain title to all furniture and trade fixtures placed on the Premises. Within thirty (30) days after completion of any Alterations, Tenant shall provide Landlord with (A) a complete set of both hard copies and CAD drawings of “as built” plans for such Alterations, and (B) a statement of all final costs of design, demolition, construction and installation of such Alterations.

Section 6.04 Covenant Against Liens

Tenant shall not allow any liens arising from any act or omission of Tenant to exist, attach to, be placed on, or encumber Landlord’s or Tenant’s interest in the Premises, the Building or the Project, or any portion of either, by operation of law or otherwise. Tenant shall not suffer or permit any lien of mechanics, material suppliers, or others to be placed against the Premises, the Building or the Project, or any portion of either, with respect to work or services performed or claimed to have been performed for Tenant or materials furnished or claimed to have been furnished to Tenant or the Premises. Landlord has the right at all times to post and keep posted on the Premises any notice that it considers necessary for protection from such liens. At least seven (7) days before beginning construction of any Alterations, Tenant shall give Landlord written notice of the expected commencement date of that construction to permit Landlord to post and record a notice of nonresponsibility. If any such lien attaches or if Tenant receives notice of any such lien, Tenant shall cause the lien to be released and removed of record, by recordation of a lien release bond or otherwise, within twenty (20) days after receipt of notice thereof. Despite any other provision of this Lease, if the lien is not released and removed within twenty (20) days after Tenant’s receipt of notice of such lien, then Landlord may immediately take all action necessary to release and remove the lien, without any duty to investigate the

validity of such lien. All expenses (including reasonable attorney fees and the cost of any bond) incurred by Landlord in connection with a lien incurred by Tenant or its removal shall be considered Additional Rent under this Lease and be immediately due and payable by Tenant. Notwithstanding the foregoing, if Tenant shall, in good faith, contest the validity of any such lien, claim or demand, then Tenant shall, at its sole expense, defend and protect itself, Landlord and the Premises, the Building, Lot 1 or the Project against the same and shall pay and satisfy any such adverse judgment that may be rendered thereon before the enforcement thereof. If Landlord reasonably elects to participate in or is made a party to any such action, Tenant shall reimburse Landlord’s reasonable attorneys’ fees and costs within ten (10) days after demand.

ARTICLE VIII

DAMAGE OR DESTRUCTION

Section 8.01 Repair of Damage by Landlord

Tenant agrees to notify Landlord in writing promptly of any damage to the Premises resulting from fire, earthquake or other event (a “Casualty”). If the Premises are damaged by a Casualty, any Common Areas of the Building or Lot 1 providing access to or parking for the Premises are damaged by Casualty to the extent that Tenant does not have reasonable access to or parking for the Premises, or the Casualty results in the Premises not being provided with essential utilities (including, without limitation, electricity, water, HVAC and passenger elevator service), and if neither Landlord nor Tenant has elected to terminate this Lease under this Article VIII, then Landlord shall promptly and diligently repair such damage and restore Common Areas, the Building (including the Building’s systems), the Premises (but not Tenant’s improvements, Alterations, personal property or trade fixtures therein), the Tenant Improvements, and/or Tenant’s parking facilities to substantially the same condition as existed before the Casualty, except for modifications request by building codes and other laws. If Tenant requests that Landlord make any modifications to the Tenant Improvements in connection with the rebuilding, Landlord may condition those modifications on: (a) confirmation by Landlord’s contractor that the modifications shall not materially increase the time needed to complete the tenant improvements, or (b) an agreement by Tenant that the modification shall not extend the Rent abatement period.

Section 8.02 Repair Notice.

Landlord shall, within sixty (60) days after the date of the Casualty, provide written notice to Tenant indicating the anticipated period for repairing the Casualty (the “Repair Notice”). The Repair Notice shall be accompanied by a statement executed by a licensed contractor or architect mutually approved by the parties, certifying the contractor’s or architect’s

opinion regarding the anticipated period for repairing the Casualty. The Repair Notice shall also state, if applicable, Landlord’s election to either repair or to terminate the Lease under Section 8.03, below.

Section 8.03 Landlord’s Option To Repair or Terminate.

Landlord may elect either to terminate this Lease or to effectuate repairs if: (a) the Repair Notice estimates that the period for repairing the Casualty exceeds two hundred seventy (270) days from the date of the Casualty; (b) the estimated repair costs of the Premises or the Building, even though covered by insurance, exceeds fifty percent (50%) of the full replacement cost, or (c) Landlord does not receive sufficient insurance proceeds (not taking into account the deductible portion of the insurance policy) to complete Landlord’s restoration obligations hereunder, and such shortfall is not due to Landlord’s failure to obtain the property insurance required by Section 7.01 hereof or any intentionally wrongful act of Landlord or any Landlord Party that results in such insurance proceeds being unavailable. Landlord’s election shall be stated in the Repair Notice. Despite any other provisions of this Article 8, Landlord may not elect to terminate this Lease under this Article 8 unless Landlord elects also to terminate the leases of all similarly situated tenants, provided that Landlord has the right under each applicable lease to terminate it based on the extent of the Casualty.

Section 8.04 Tenant’s Option to Terminate.

If the Repair Notice indicates that the anticipated period for repairing the Casualty exceeds two hundred seventy (270) days from the date of Casualty, then Tenant may elect to terminate this Lease by providing written notice (“Tenant’s Termination Notice”) within thirty (30) days after receiving the Repair Notice. If Tenant does not elect to terminate within this thirty (30) day period, then, subject to the next succeeding sentence, Tenant shall be considered to have waived the option to terminate pursuant to this Section 8.04.

Section 8.05 Rent Abatement Due to Casualty.

Landlord and Tenant agree that, to the extent Landlord receives rental abatement insurance proceeds therefore (or would have received such proceeds if: (i) Landlord had maintained the insurance required of Landlord pursuant to Section 7.01 hereof, or (ii) Landlord or a Landlord Party had not performed an intentionally wrongful act that results in such insurance being unavailable), Tenant’s Rent shall fully abate during the period beginning on the later of (a) the date of the Casualty, or (b) the date on which Tenant ceases to occupy the Premises and end on the date of the completion of Landlord’s restoration obligations (the “Casualty Abatement Period”). If, however, Tenant is able to occupy and does occupy a portion of the Premises, then Rent shall be abated during the Casualty Abatement Period only for the portion of the Premises not occupied by Tenant. Subject to Section 8.04. the Rent abatement provided in this Section 8.05 is Tenant’s sole remedy due to the occurrence of the Casualty.

Section 8.06 Damage Near End of Lease Term.

Notwithstanding any other provision of this Article 8, if the Premise or the Building or the Common Areas necessary for parking and/or access to the Premises are destroyed or damaged by a Casualty during the last twelve (12) months of the Lease Term, then Landlord and

Tenant shall each have the option to terminate this Lease by giving written notice to the other of the exercise of that option within thirty (30) days after the date of the Casualty; provided, however, that Landlord may not elect to terminate this Lease under this Article 8 unless Landlord elects also to terminate the Lease of all similarly situated tenants, provided that Landlord has the right under each applicable lease to terminate it based on the extent of the Casualty. If Tenant is not then in default beyond all applicable notice and cure periods under this Lease, Tenant may negate Landlord’s election to terminate under this Section 8.06 by electing, within ten (10) business days after receipt of Landlord’s termination notice, to exercise an unexercised Option. If Tenant negates Landlord’s election, then this Lease shall continue in effect unless Landlord has the right to, and elects to, terminate this Lease under Section 8.03, above.

Section 8.07 Effective Date of Termination; Rent Apportionment.

If Landlord or Tenant elects to terminate this Lease under this Article 8, then the termination shall be effective thirty (30) days after deliver of the notice of such election. Tenant shall pay Rent, properly apportioned, up to the date of the Casualty. After the effective date of the termination, Landlord and Tenant shall be discharged from all future obligations under this Lease, except those provisions that, by their express terms, survive the expiration or earlier termination of this Lease.

Section 8.08 Waiver of Civil Code Remedies.

Tenant hereby expressly waives any rights to terminate this Lease upon damage or destruction to the Premises, including without limitation any rights pursuant to the provisions of Section 1932, Subdivisions 1 and 2 and Section 1933, Subdivision 4, of the California Civil Code, as amended from time to time, and the provisions of any similar law hereinafter enacted.

Section 8.09 No Abatement of Rentals.

Except as otherwise expressly provided in Section 8.05 above, the Base Rent, Additional Rent and other charges due under this Lease shall not be reduced or abated by reason of any damage or destruction to the Premises, and Landlord shall be entitled to all proceeds of the insurance maintained pursuant to Section 7.01 above. Landlord shall not be liable for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant’s business (including, without limitation, loss of business, profits or goodwill), resulting in any way from any damage or the repair thereof.

Section 8.10 No Liability for Tenant’s Alterations or Personal Property.

In no event shall Landlord have any liability for, nor shall it be required to repair or restore, any injury or damage to Tenant’s Alterations or personal property or to any other personal property of others in or upon the Premises, the Building or Lot 1 or the Project.

ARTICLE IX

REAL PROPERTY TAXES

Section 9.01 Payment of Taxes

(a) Throughout the Lease Term, Landlord shall pay all real property taxes, including, without limitation, any escaped or supplemental tax and any form of real estate tax or assessment, general, special, ordinary or extraordinary, and any license, fee, charge, excise or imposition imposed, assessed or levied on or with respect to the Building or the Project or any part thereof, or any legal or equitable interest of Landlord therein, by any Federal, State, County, City or other political subdivision or public authority having the direct or indirect power to tax, including, without limitation, any improvement district or any community facilities district, as well as any government or private cost sharing agreement assessments made for the purpose of augmenting or improving the quality of services and amenities normally provided by government agencies (“Real Property Taxes”) and any tax, fee, charge, imposition or excise described in subsection 9.01(b) below. Notwithstanding anything to the contrary contained herein, “Real Property Taxes” shall not include any net income taxes, franchise taxes, or any succession, estate or inheritance taxes of Landlord or any penalties due to Landlord’s late or non-payment of any Real Property Taxes. All such payments shall be made by Tenant to Landlord on an estimated basis, as is described in Section 4.04 hereof; provided, however, that, at Landlord’s election, such payments may be made by Tenant directly to the taxing authority pursuant to Section 4.04 hereof no later than thirty (30) days after Landlord’s delivery to Tenant of a statement of the real property tax due (but in no event later than ten (10) days prior to the date such real property taxes would be delinquent), together with a copy of the applicable tax bill except to the extent such amounts are included in estimated real property taxes paid monthly pursuant to Section 4.04(b).

(b) Except as otherwise expressly provided herein below, if at any time during the Lease Term, the State of California or any political subdivision of the state, including any county, city, city and county, public corporation, district, or any other political entity or public corporation of this state, levies or assesses against Landlord a tax, fee, charge, imposition or excise on rents under leases of space in the Building or Lot 1 or the Project, the square footage of the Building or the Project, the act of entering into leases of space in the Building or Lot 1 or the Project, or the occupancy of tenants of the Building or Lot 1 or the Project, or levies or assesses against Landlord any other tax, fee, or excise, however described, including, without limitation, a so-called value added, business license, transit, commuter, environmental or energy tax fee, charge or excise or imposition related to the Building or Lot 1 or the Project, as a direct substitution in whole or in part for, or in addition to, any Real Property Taxes (collectively, “Additional Real Property Taxes”), then the same shall be included in “Real Property Taxes” for all purposes hereunder; provided that, notwithstanding the foregoing, if any such Additional Real Property Taxes pertain solely to (i) Rent under this Lease (as opposed to under all leases of space in the Building or Lot 1 or the Project), (ii) the square footage of the Premises (as opposed to the square footage of the Building or Lot 1 or the Project), (iii) the act of entering into this Lease, or (iv) the occupancy of Tenant (as opposed to all tenants or occupants of the Building or Lot 1 or the Project) (as opposed to all leases of space in the Building or Lot 1 or the Project), then such Additional Real Property Taxes shall not be included in “Real Property Taxes,” and shall be the sole obligation and liability of Tenant and shall be paid by Tenant, as Additional Rent, ten (10) days before delinquency (or, if such Additional Real Property Taxes are levied

against Landlord or Landlord’s property, then Landlord shall pay the same before delinquency and Tenant shall reimburse Landlord the amount of the same within ten (10) days after written demand accompanied by a copy of Landlord’s tax bill); and further provided that, if any such Additional Real Property Taxes pertain not only to Lot 1 or the Project, but to additional property of Landlord located outside Lot 1 or the Project as well, then “Real Property Taxes” shall only include a portion of such Additional Real Property Taxes, which portion shall be computed upon the amounts and at the rates that otherwise would be payable if Lot 1 or the Project were the only property of Landlord.

(c) Landlord shall provide Tenant with copies of all tax and assessment bills on the Premises promptly upon Landlord’s receipt of Tenant’s written request therefor, and Landlord shall also provide to Tenant evidence of payment promptly upon Landlord’s receipt of Tenant’s written request therefor.

(d) With respect to taxes and assessments which may lawfully be paid in installments, “Real Property Taxes” for any period during the Lease Term shall include only such portion of the same which is payable within such period and any interest payable thereon computed (whether or not such is the case) as if Landlord had elected to pay the same over the longest period permitted by law.

(e) If Landlord shall obtain any abatement or refund on account of any Real Property Taxes or other Additional Real Property Taxes as to which Tenant shall have made payments hereunder, then Landlord shall promptly refund to Tenant an equitable portion of any such abatement or refund, after deducting therefrom the reasonable costs and expenses incurred by Landlord in obtaining such abatement or refund.

Section 9.02 Proration for Partial Years

If any Real Property Taxes paid by Tenant shall cover any period prior to the Commencement Date or after the Expiration Date, then Tenant’s Share of such Real Property Taxes shall be prorated on a day-for-day basis to cover only the period of time within the applicable tax fiscal year during which this Lease shall be in effect.

Section 9.03 Personal Property Taxes

(a) Tenant shall pay prior to delinquency all taxes imposed, assessed against and levied upon trade fixtures, furnishings, equipment and all other personal property of Tenant contained in the Premises or elsewhere. When possible, Tenant shall cause said trade fixtures, furnishings, equipment and all other personal property to be assessed and billed separately from the real property of Landlord.

(b) If any of Tenant’s said personal property shall be assessed with Landlord’s real property, Tenant shall pay to Landlord, as Additional Rent, the amount of taxes attributable to Tenant’s personal property within ten (10) days after receipt of a written statement thereof.

(c) If Tenant shall fail to pay any such taxes, Landlord shall have the right to pay the same, in which case Tenant shall repay such amount to Landlord, as Additional Rent, with Tenant’s next installment of Rent, together with interest at the Agreed Rate.

ARTICLE X

UTILITIES

(a) HVAC. Tenant shall pay, prior to delinquency and throughout the Lease Term, all charges for water, gas, heating, ventilation, air conditioning, cooling, sewer, telephone, electricity, garbage, janitorial service, landscaping and all other services and utilities supplied to the Premises, including Tenant’s Share of any such services or utilities which are not separately metered for or billed to the Premises. Landlord may, at Tenant’s expense, install devices which separately meter Tenant’s consumption of utilities. All charges for utilities and services which are separately metered to the Premises or which are provided directly to Tenant or the Premises by utility companies or third party providers shall be paid directly by Tenant to such utility companies or third party providers prior to delinquency. All charges for utilities and services for the sole benefit of Tenant or the Premises which are billed to and paid by Landlord directly shall be paid by Tenant to Landlord within ten (10) days after receipt of an invoice therefor. All other charges for utilities and services shall be included in Operating Expenses recoverable by Landlord in accordance with Article IV. The disruption, failure, lack or shortage of any service or utility with respect to the Premises, the Building, Lot 1 or the Project due to any cause whatsoever shall not affect any obligation of Tenant hereunder, and Tenant shall faithfully keep and observe all the terms, conditions and covenants of this Lease and pay all Rent due hereunder, all without diminution, credit or deduction; provided, however, if such disruption, failure, lack or shortage is caused by Landlord’s failure to observe or perform its obligations hereunder, then, within thirty (30) days after receipt of written notice from Tenant specifying such failure, Landlord shall initiate the cure of such failure and thereafter shall diligently prosecute said cure to completion.

(b) Generator Service.

(i) Throughout the Lease Term, Landlord shall provide to Tenant Tenant’s Building Share of power from the Generator for the purpose of providing emergency electrical service to the Premises (hereinafter referred to as the “Generator Service”). Throughout the Lease Term, Landlord agrees to supply fuel to the Generator and to maintain, repair, use and operate the Generator in good working order.

(ii) Landlord shall have the right, by giving reasonable advance written notice to Tenant, to temporarily suspend service of the Generator and/or any systems, services or utilities serving the Generator for so long as may become necessary in order to allow the making of any and all repairs, replacements, changes, modifications, improvements, or substitutions to the Generator. If Landlord temporarily suspends service of the Generator pursuant to, and in accordance with, this section, the period for which such service is suspended shall be reasonable with respect to the particular reason for such temporary suspension of service and, except as may otherwise be expressly provided in the Lease with respect to any suspension of services provided to Tenant, Landlord shall not be subject to any liability nor shall Tenant be entitled to any compensation or abatement of the Base Rent or Additional Rent under the Lease with respect to the temporary suspension of service set forth in this section. Landlord agrees to use commercially reasonable efforts to resume the service of the Generator and/or the systems, services or utilities serving the Generator as soon as possible. Tenant is hereby authorized to arrange for the visual inspection and performance of preventative maintenance tests or

emergency power tests (a/k/a pull the plug test) by licensed technicians consistent with Tenant’s practices, provided that no such inspection or test shall be performed by Tenant without the presence of Landlord’s agent, employee or other representative.

(iii) If Landlord temporarily suspends service of the Generator in accordance the above and such suspension is reasonably expected to last more than twenty-four (24) hours, then Landlord shall, at Landlord’ sole cost and expense, install, operate, maintain and use an outdoor truck mounted portable generator or other temporary generator (the “Temporary Generator”) to provide Tenant with a continuous supply of backup power available from such Temporary Generator in an amount at least equal to their allocation of the Generator capacity throughout the period that Landlord temporarily suspends the service of the Generator and/or any systems, services or utilities serving the Generator until the date that Landlord resumes such service.

(c) After-Hours Service. Throughout the Lease Term, Landlord agrees to provide Tenant with HVAC service during nonbusiness hours upon reasonable advance verbal notice. Tenant shall reimburse Landlord for its actual cost to provide such after-hour service within thirty (30) days of Tenant’s receipt of Landlord’s invoice. If more than one tenant directly benefits from the after-hour services, then the cost shall be allocated proportionately between or among the benefiting tenants based upon the amount of time each tenant benefits and the square footage each lease.

ARTICLE XI

ASSIGNMENT AND SUBLETTING

Section 11.01 Landlord’s Consent Required

Except as provided in Section 11.02, Tenant shall not voluntarily or by operation of law assign, transfer, mortgage, sublet, license or otherwise transfer or encumber all or any part of Tenant’s interest in this Lease or in the Premises or any part thereof, without Landlord’s prior written consent; provided, however, Landlord shall not unreasonably withhold, condition or delay its consent to an assignment of this Lease or a subletting of all or a portion of the Premises. Landlord shall respond in writing to Tenant’s request for consent hereunder in a timely manner and any attempted assignment, transfer, mortgage, encumbrance, subletting or licensing without such consent shall be void, and shall constitute a breach of this Lease. Tenant shall reimburse Landlord upon demand for Landlord’s reasonable costs and expenses (including reasonable attorneys’ fees, architect fees and engineering fees) involved in reviewing any request for consent whether or not such consent is granted; provided, however, in no event shall such amount exceed $10,000.

Section 11.02 Tenant Affiliates

Tenant, without Landlord’s prior written consent, but upon not less than ten (10) business days prior written notice to Landlord, may assign this Lease, or sublet all or any portion of the Premises, to any business entity which controls, is controlled by, or is under common control with Tenant, or to any business entity resulting from the merger or consolidation with Tenant, or to any person or entity which acquires a controlling interest of Tenant’s stock if Tenant is no

longer a publicly traded company (“Affiliate”), provided that said assignee or subtenant (i) has a net worth equal to or greater than that of Tenant as of the date of this Lease, and (ii) assumes, in full, the obligations of Tenant under this Lease arising from and after such assignment. Any portion of the Premises which is assigned or sublet to an Affiliate of Tenant shall not be included in the calculation of subleased, assigned or transferred Rentable Area for the purposes of Section 11.06 and Section 17.26.

Section 11.03 No Release of Tenant

Regardless of whether or not Landlord’s consent is required or obtained, no subletting or assignment (including, without limitation, to an Affiliate) shall release Tenant of Tenant’s obligations under this Lease or alter the primary liability of Tenant to pay the Rent and to perform all other obligations to be performed by Tenant hereunder. The acceptance of Rent by Landlord from any other person shall not be deemed consent to any subsequent assignment or subletting. In the event of any default in the payment of Rent or performance of any obligation hereunder by any assignee or successor of Tenant, Landlord may proceed directly against Tenant without the necessity of exhausting remedies against said assignee or successor.

Section 11.04 Excess Rent

In the event Landlord shall consent to a sublease or an assignment, Tenant shall pay to Landlord, as Additional Rent, fifty percent (50%) of all net proceeds (including the fair market value of all non-cash consideration) collected or received by Tenant from a subtenant or assignee which are in excess of the Base Rent and Additional Rent due and payable with respect to the subject space pursuant to Article IV for the time period encompassed by the sublease or assignment term, after first deducting reasonable leasing commissions paid by Tenant with respect to such sublease or assignment. With respect to an assignment, Tenant shall make such payment on the effective date of such assignment. With respect to a sublease, Tenant shall make such payment on a monthly basis on the first day of each calendar month after Tenant receives such amount from the subtenant. Landlord expressly acknowledges and agrees that it shall not be entitled to consideration received by Tenant in connection with an assignment of this Lease or an sublease of the Premises to an Affiliate.

Section 11.05 Information to be Provided

Tenant’s written request to Landlord for consent to an assignment or subletting or other form of transfer shall be accompanied by (a) the name and legal composition of the proposed transferee; (b) the nature of the proposed transferee’s business to be carried on in the Premises; (c) the material terms and provisions of the proposed transfer agreement (including, without limitation, a description of the portion of the Premises to be transferred, and the effective date of the proposed transfer); (d) a copy of all executed and/or proposed documentation pertaining to the proposed transfer; and (e) such financial and other reasonable information as Landlord may promptly request concerning the proposed transferee.

Section 11.06 Landlord’s Recapture Rights

(a) Landlord’s Recapture Rights

Notwithstanding any other provision of this Article 11, if Tenant desires to assign, sublease or otherwise transfer to any person or entity (other than an Affiliate) any interest in this Lease or the entire Premises or any part thereof, then Tenant shall deliver to Landlord a written request for consent, together with all of the information specified in Section 11.05 above. If such transfer (together with all other assignments, subleases or transfers then in effect) would affect seventy five percent (75%) of the Rentable Area of the Premises in the aggregate (such total affected portion of the Rentable Area of the Premises being referred to herein as the “Recapture Space”) for more than fifty percent (50%) of the remainder of the Lease Term, then Landlord shall have the option to recapture all, but not less than all, of the Recapture Space, which option shall be exercisable only by giving written notice to Tenant (“Recapture Notice”) within ten (10) days after Landlord’s receipt of Tenant’s request for consent. A timely Recapture Notice shall terminate this Lease with respect to the Recapture Space effective as of the date specified in Tenant’s request for consent as the effective date of the proposed transfer. Landlord’s recapture rights shall be subject to the rights of any assignee, subtenant or other transferee of Tenant, as set forth in any assignment, sublease or other transfer agreement to which Landlord previously has consented, but subject to the terms and conditions set forth in Landlord’s consent thereto; any such assignment, sublease or other transfer agreement shall be assigned to Landlord as of the effective date of Landlord’s recapture.

(b) Consequences of Recapture

If Landlord recaptures less than the entire Premises pursuant to Section 11.06(a) above, then the Rent reserved herein shall be prorated on the basis the of the Rentable Area of the portion of the Premises retained by Tenant in proportion to the Rentable Area contained in the Premises. This Lease, as so amended, shall continue thereafter in full force and effect. Either party may require written confirmation of the amendments to this Lease necessitated by Landlord’s recapture of the Recapture Space. If Landlord recaptures the Recapture Space, then Landlord, at Landlord’s sole expense, shall promptly (but in all events prior to Landlord tendering possession of the Recapture Space to a third party) construct, paint, and furnish any partitions required to segregate the Recapture Space from the remaining Premises retained by Tenant, as well as arrange for separate provision of utilities and services (including, at Landlord’s option, installation of separate meters if and to the extent the premises are served by separately metered utilities) (collectively, the “Demising Improvements”). Landlord agrees that the Demising Improvements shall be completed pursuant to plans and specifications reasonably acceptable to Tenant and that Landlord shall use commercially reasonable efforts to minimize any interference with Tenant’s use and enjoyment of the Premises during the construction of any Demising Improvements.

ARTICLE XII

DEFAULTS; REMEDIES

Section 12.01 Defaults

The occurrence of any one or more of the following events shall constitute a material default and breach of this Lease by Tenant:

(a) The vacation or abandonment of all or a substantial portion of the Premises by Tenant, or the commission of waste at the Premises, or the making of an assignment, subletting or other transfer in violation of Article XI; provided however, abandonment and/or vacation shall be considered to not occur if the Premises are maintained and occupied to the extent necessary to maintain the insurance on each and every portion of the Premises;

(b) The failure by Tenant to make any payment of Base Rent as and when due, if such failure continues for a period of five (5) business days after written notice thereof from Landlord to Tenant. In the event that Landlord serves Tenant with a Notice to Pay Rent or Quit in the form required by applicable law, such Notice shall constitute the notice required by this paragraph, provided that the cure period stated in such Notice shall be five (5) business days rather than the statutory three (3) days;

(c) The failure by Tenant to make any payment of any other sum owing under this Lease as and when due, if such failure continues for a period of five (5) business days after written notice thereof from Landlord to Tenant. In the event that Landlord serves Tenant with a Notice to Pay Rent or Quit in the form required by applicable law, such Notice shall constitute the notice required by this paragraph, provided that the cure period stated in such Notice shall be five (5) business days rather than the statutory three (3) days;

(d) Tenant’s failure to provide (i) any supplemental letter of credit as required by Section 2.04(c) or (ii) any instrument or assurance as required by Section 7.05 or (iii) estoppel certificate as required by Section 15.01 or (iv) any document subordinating this Lease to a Lender’s deed of trust as required by Section 17.13, if any such failure continues for ten (10) business days after written notice of the failure. In the event Landlord serves Tenant with a Notice to Perform Covenant or Quit in the form required by applicable law, such Notice shall constitute the notice required by this paragraph, provided that the cure period stated in such Notice shall be ten (10) business days rather than the statutory three (3) days;

(e) The failure by Tenant to observe or perform any of the covenants, conditions or provisions of this Lease to be observed or performed by Tenant, other than described in paragraphs (a), (b), (c) or (d) of this Section 12.01, if such failure continues for a period of thirty (30) days after written notice thereof from Landlord to Tenant; provided, however, that if the nature of Tenant’s default is such that more than thirty (30) days are reasonably required for its cure, then Tenant shall not be deemed to be in default if Tenant commences such cure within said thirty (30) day period and thereafter diligently prosecutes such cure to completion. In the event Landlord serves Tenant with a Notice to Perform Covenant or Quit in the form required by applicable law, such Notice shall constitute the notice required by

this paragraph, provided that the cure period stated in such Notice shall be thirty (30) days rather than the statutory three (3) days;

(f) (i) The making by Tenant of any general arrangement or assignment for the benefit of creditors; (ii) the filing by Tenant of a voluntary petition in bankruptcy under Title 11 U.S.C. or the filing of an involuntary petition against Tenant which remains uncontested for a period of sixty (60) days; (iii) 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; or (iv) 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, provided, however, in the event that any provisions of this Section 12.01(e) is contrary to any applicable law, such provision shall be of no force or effect; and

(g) The discovery by Landlord that any financial statement given to Landlord by Tenant, or any future guarantor of Tenant’s obligations hereunder, was materially false.

Section 12.02 Remedies

In the event of any such material default and breach by Tenant, Landlord may at any time thereafter, and without limiting Landlord in the exercise of any right or remedy which Landlord may have by reason of such default and breach:

(a) Terminate Tenant’s right to possession of the Premises by any lawful means, in which case this Lease shall terminate and Tenant shall immediately surrender possession of the Premises to Landlord. In such event Landlord shall be entitled to recover from Tenant all damages incurred by Landlord by reason of Tenant’s default including, but not limited to, (i) the cost of recovering possession of the Premises including reasonable attorney’s fees related thereto; (ii) the worth at the time of the award of any unpaid Rent that had been earned at the time of the termination, to be computed by allowing interest at the Agreed Rate but in no case greater than the maximum amount of interest permitted by law, (iii) the worth at the time at the time of the award of the amount by which the unpaid Rent that would have been earned between the time of the termination and the time of the award exceeds the amount of unpaid Rent that Tenant proves could reasonably have been avoided, to be computed by allowing interest at the Agreed Rate but in no case greater than the maximum amount of interest permitted by law, (iv) the worth at the time of the award of the amount by which the unpaid Rent for the balance of the Lease Term after the time of the award exceeds the amount of unpaid Rent that Tenant proves could reasonably have been avoided, to be computed by discounting that amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of the award plus one percent (1%), (v) any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform obligations under this Lease, including, but not limited to, reasonable brokerage commissions and advertising expenses, expenses of remodeling the Premises for a new tenant (whether for the same or a different use), and any market-rate concessions made to obtain a new tenant, and (vi) any other amounts, in addition to or in lieu of those listed above, that may be permitted by applicable law.

(b) Maintain Tenant’s right to possession as provided in Civil Code Section 1951.4 (Landlord may continue lease in effect after Tenant’s breach and abandonment

and recover rent as it becomes due, if Tenant has the right to sublet or assign, subject only to reasonable limitations), in which case this Lease shall continue in effect whether or not Tenant shall have abandoned the Premises. In such event Landlord shall be entitled to enforce all of Landlord’s rights and remedies under this Lease, including the right to recover the Rent as it becomes due hereunder.

(c) Pursue any other remedy now or hereafter available to Landlord under the laws or judicial decisions of the state of California.

Section 12.03 Default by Landlord

Landlord shall not be in default under this Lease unless Landlord fails to perform obligations required of Landlord within thirty (30) days after receipt of written notice from Tenant to Landlord and to the holder of any first mortgage or deed of trust covering the Premises whose name and address shall have theretofore been furnished to Tenant in writing, specifying that Landlord has failed to perform such obligation; provided, however, that if the nature of Landlord’s obligation is such that more than thirty (30) days are reasonably required for performance then Landlord shall not be in default if Landlord commences performance within such thirty (30) day period and thereafter diligently prosecutes the same to completion. In the event Landlord does not commence performance of any maintenance or repair required of Landlord hereunder within the thirty (30) day period provided herein, and in the event that such maintenance or repair relates to improvements which are wholly within the Premises (not including any Building core systems or equipment), Tenant may perform such maintenance or repair, and Tenant shall be entitled to prompt reimbursement by Landlord of Tenant’s reasonable costs and expenses in taking such action, together with interest thereon at the Agreed Rate. Tenant waives any right to terminate this Lease or 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.

Section 12.04 Late Charges

Tenant and Landlord hereby acknowledges that late payment by either of them to the other of Rent or any other sums due hereunder will cause the recipient of such amounts to incur costs not contemplated by this Lease, the exact amount of which will be extremely difficult to ascertain. Such costs include, but are not limited to, processing and accounting charges and late charges which may be imposed on Landlord by the terms of any mortgage or trust deed covering the Premises. Accordingly, if any installment of Rent or any other sum due from Tenant or Landlord shall not be received by the other or its designated agent within five (5) business days after such amount is due and owing, the delinquent party shall pay a late charge equal to five percent (5%) of such amount each time a late charge is payable during the Lease Term. The parties hereby agree that such late charge represents a fair and reasonable estimate of the costs the recipient will incur by reason of late payment. Acceptance of such late charge shall in no event constitute a waiver of default with respect to such overdue amount, nor prevent either party from exercising any of the other rights and remedies granted hereunder.

Section 12.05 Landlord’s Right to Perform Tenant’s Obligations

Except as otherwise expressly stated in this Lease, all obligations to be performed or observed by Tenant under this Lease shall be performed or observed by Tenant at Tenant’s expense and without any reduction of Rent. So long as Landlord provides Tenant with at least thirty (30) days’ prior written notice (or whatever other notice and grace period is specifically provided for in this Lease), Landlord may perform or observe any obligation of Tenant which is in default hereunder if such default is not cured within such thirty (30) day period, without waiving Landlord’s other rights and remedies for Tenant’s failure to perform or observe any obligations under this Lease and without releasing Tenant from any such obligations. Within thirty (30) days after receiving a statement from Landlord, Tenant shall pay to Landlord the amount of third-party out-of-pocket expenses reasonably incurred by Landlord in performing or observing Tenant’s obligation.

ARTICLE XIII

CONDEMNATION OF PREMISES.

Section 13.01 Total Condemnation

If the entire Premises or the portions of the Building or the Project required for reasonable access to, or the reasonable use of, the Premises shall be permanently taken by condemnation at any time during the Lease Term (whether by exercise of governmental power or the sale or transfer by Landlord to any condemnor under threat of condemnation or while proceedings for condemnation are pending), then this Lease shall terminate as of the earlier of (a) the date on which title vests in the condemnor, or (b) the date Tenant is dispossessed of the Premise by the condemnor. Upon such condemnation, all Rent shall be paid up to the date of the termination of the Lease.

Section 13.02 Partial Condemnation

Except as otherwise provided in this Section 13.02, if less than all of the Premises is taken by condemnation during the Lease Term (whether by exercise of governmental power or the sale or transfer by Landlord to any condemnor under threat of condemnation or while proceedings for condemnation are pending), then this Lease shall remain in full force and effect. If a partial taking leaves the Premises unfit for the conduct of Tenant’s business, then Tenant shall have the right to terminate this Lease effective as of the earlier of the date (a) title vests in the condemnor, or (b) on which Tenant is dispossessed by the condemnor. Tenant may elect to exercise its right to terminate this Lease pursuant to this Section 13.02, if at all, by delivering written notice to Landlord within thirty (30) days after receipt of notice of such condemnation. All Rent shall be paid up to the date of termination, and Tenant shall have no claim against Landlord for the value of the unexpired portion of the Lease Term. If this Lease shall not be terminated, then the Rent reserved herein shall be prorated on the basis the of the Rentable Area of the portion of the Premises retained by Tenant in proportion to the Rentable Area contained in the Premises immediately prior to the partial taking. If Tenant’s continued use of the Premises requires alterations and repair by reason of a partial taking, all such alterations and repair shall be made by Landlord at Landlord’s expense. Tenant waives all rights it may have under California

Code of Civil Procedure Section 1265.130 or otherwise, to terminate this Lease based on partial condemnation.

Section 13.03 Award to Tenant

In the event of any condemnation (whether total or partial), Tenant shall have the right to claim and recover from the condemning authority such compensation as may be separately awarded or recoverable by Tenant for loss of Tenant’s business fixtures, or equipment belonging to Tenant immediately prior to the condemnation. In the event of any condemnation (whether total or partial), the entire condemnation award shall belong to Landlord (including, without limitation, any “bonus value” of the leasehold estate - OR - amount attributable to any excess of the market value of the Premises for the remainder of the Lease Term over the then present value of the Rent payable for the remainder of the Lease Term), and Tenant shall have no right to recover from Landlord or from the condemning authority for any claims arising out of such taking; provided, however, notwithstanding the foregoing, as long as the award payable to Landlord is not reduced thereby, Tenant shall have the right to make a separate claim in the condemnation proceeding for, and to recover from the condemning authority, such compensation as may be separately awarded or recoverable by Tenant for (a) loss of Tenant’s business fixtures, or equipment belonging to Tenant immediately prior to the condemnation, (b) the taking of the unamortized value (using the Lease Term as the amortization period) of any Tenant Improvements paid for by Tenant which are not removed by Tenant, and (c) Tenant’s moving expenses.

Section 17.13 Lease to be Subordinate

Tenant agrees that this Lease is and shall be, at all times, subject and subordinate to (a) the lien of any mortgage, deed of trust or other encumbrances now existing against the Premises, the Building or Lot 1 or the Project, including all modifications, renewals, and extensions thereof, and (b) all ground or underlying leases now existing affecting the Building or Lot 1 or the Project, including all modifications, renewals, and extensions thereof. Landlord agrees that it shall be an express condition precedent to Tenant’s obligations under this Lease that Landlord, at its sole cost and expense, provide Tenant with subordination, non-disturbance and attornment agreements (“SNDA”) substantially in the form of Exhibit E from the holder of each mortgage, deed of trust or other encumbrances and the ground lessor under any ground lease within sixty (60) days of the mutual execution and delivery of this Lease; provided, however, that if Landlord fails to deliver the SNDA within such time period, then Tenant shall thereafter have the right to terminate this Lease until such time as the SNDA is delivered to Tenant fully executed and acknowledged by Landlord and the holder of each mortgage, deed of trust or other encumbrances and the ground lessor under any ground lease. If, after the mutual execution and delivery of this Lease, Landlord elects to encumber the Property with a new mortgage, deed of trust or encumbrance or enter into a ground lease affects the Building or Lot 1, then Tenant shall execute and deliver any commercially reasonable documents confirming the subordination of this Lease within fifteen (15) business days after delivery of same by Landlord, so long as the mortgagee, beneficiary, or ground or underlying Landlord agrees therein that this Lease will not be terminated if Tenant is not in default beyond all applicable notice and cure periods following either the foreclosure of any such mortgage, deed or trust or other encumbrance (or the granting of a deed in lieu thereof) or the termination of any such ground or underlying lease. Notwithstanding any subordination of this Lease, in the event of either the foreclosure of any such mortgage, deed or trust or other encumbrance (or the granting of a deed in lieu thereof) or the termination of any such ground or underlying lease, Tenant shall attorn to, and become the tenant of, the successor to Landlord (i.e., such mortgagee, beneficiary or other successor to Landlord by foreclosure or deed in lieu thereof, or such ground or underlying Landlord, as the case may be), at the option of such successor to Landlord; provided however, in

no event shall any such successor to Landlord (i) be liable for any previous act or omission of Landlord under this Lease except to cure continuing defaults to the extent it has been provided with written notice thereof and an opportunity to cure, (ii) be subject to any offset, defense or counterclaim against Landlord which shall theretofore have accrued to Tenant under this Lease, (iii) have any obligation with respect to any security deposit, unless the same shall have been paid or physically delivered to such successor, or (iv) be bound by any Rent paid more than one month in advance to Landlord or any prior landlord or owner.

Section 17.14 Attorneys’ Fees

In the event any action or proceeding is brought by any party to enforce or interpret the provisions of this Lease, or if any other action or proceeding is brought arising out of or relating to this Lease, the prevailing party in such action or proceeding shall be entitled to recover the reasonable fees of its attorneys, experts and arbitrators, and other costs of suit.

Section 17.15 Signs

(a) Subject to the terms of this Section 17.15, throughout the Lease Term, Tenant shall have the exclusive right, at Tenant’s sole expense, to install and maintain Tenant’s company name on the Exterior Building Parapet Sign on the Building located in the location depicted on Exhibit J attached hereto and incorporated herein, so long as Tenant continues to lease at least three (3) full floors of the Building and occupies at least fifty percent (50%) of the Premises.

Except as set forth above, Tenant shall not place any additional signs outside the Premises (or visible from outside the Premises) without Landlord’s prior written consent, which consent shall not be unreasonably withheld; provided, however, any such signage shall be subject to the terms of this Section 17.15.

(c) Tenant’s identification signage on the exterior of the Building, in the Project Common Areas (including the monument signs) and the Building Common Areas and Tenant’s other signage outside the Premises (or visible from outside the Premises) shall be referred to herein, collectively, as “Tenant’s Signage.” All aspects of Tenant’s Signage, including, but not limited to, quality, design, color, style, lighting, size and specifications, as applicable, shall be (i) consistent with Landlord’s signage policy set forth on Exhibit D attached hereto, (ii) subject to Landlord’s prior written approval which Landlord will not unreasonably withhold, condition or delay, (iii) in compliance with all applicable governmental laws, ordinances, rules, regulations, codes and approvals, and (iv) the Moffett Towers Multi-Tenant Signage Standards Final dated 9/19/08 as approved by the City of Sunnyvale, together with any amendments or supplements thereto. Tenant shall be responsible, at its sole cost and expense, for the installation, maintenance, repair and replacement of Tenant’s Signage. Upon the expiration or earlier termination of this Lease, Tenant shall, at Tenant’s sole cost and expense,

remove Tenant’s Signage and repair any damage resulting therefrom. Notwithstanding anything to the contrary contained in this Section 17.15, Landlord, at its election, shall have the right to perform any and all installation, maintenance, repair, replacement and removal of Tenant’s Signage and to repair any damage resulting therefrom, in which instance Tenant shall pay to Landlord upon demand the third-party out-of-pocket reasonable cost of such installation, maintenance, repair, replacement, removal and repair within thirty (30) days after receipt of an invoice. Tenant shall be responsible, at its sole cost and expense, for obtaining all governmental approvals for Tenant’s Signage, provided that Tenant shall not submit any applications or requests for governmental approvals without first obtaining Landlord’s prior written approval thereof (which approval shall not be unreasonably withheld, conditioned or delayed), and provided further that Tenant shall provide written notice to Landlord of all hearings and meetings with any applicable governmental authority regarding Tenant’s applications or requests for governmental approvals not later than two (2) business days prior thereto. Subject to the foregoing, upon request by Tenant from time to time, Landlord agrees (at no material cost to Landlord that Tenant does not agree in advance to reimburse) to reasonably cooperate with Tenant in connection with Tenant’s efforts to obtain all governmental approvals for Tenant’s Signage, provided that Landlord shall have no obligation (and Tenant shall have no right) to agree to or to comply with any conditions which may be imposed upon Landlord or the Building or Lot 1 or the Project in connection with any governmental approvals for Tenant’s Signage. Tenant hereby acknowledges and agrees that the governmental approvals for Tenant’s Signage are not conditions to the validity of this Lease, and in the event Tenant fails to obtain any such approvals, this Lease shall continue in full force and effect in accordance with its terms, except that Tenant shall have no right with respect to Tenant’s Signage which is not so approved. The rights contained in this Section 17.15 with respect to Tenant’s Signage shall be personal to the originally named Tenant herein (“Original Tenant”) or an Affiliate and may only be exercised by the Original Tenant or an Affiliate (and not by any other assignee, subtenant or transferee) if the Original Tenant or an Affiliate then occupies the entire Premises. Should the name of Original Tenant be legally changed or should Tenant’s Signage be assigned to an Affiliate (any such other name referred to herein as a “New Name”), Tenant, at its sole cost and expense, shall be entitled to modify Tenant’s name as the same appears on Tenant’s Signage to reflect Tenant’s New Name, so long as Tenant’s New Name is not an objectionable name. As used herein, the term “Objectionable Name” shall mean any name which relates to an entity which is of a character or reputation, or is associated with a political orientation or faction, which is inconsistent with the quality of the Building or Lot 1 or the Project, or which would otherwise reasonably offend a landlord of similar Buildings in the vicinity of the Building.

Section 17.16 Merger

The voluntary or other surrender of this Lease by Tenant, or a mutual cancellation thereof, or a termination by Landlord, shall not work a merger, and shall, at the option of Landlord, terminate all or any existing subtenancies or may, at the option of Landlord, operate as an assignment to Landlord of any or all of such subtenancies.

Section 17.17 Quiet Possession

Landlord covenants that Tenant, upon timely paying the Rent for the Premises and timely observing and performing all of the covenants, conditions and provisions on Tenant’s part to be

observed and performed hereunder, shall have quiet possession of the Premises for the Lease Term, subject to all of the covenants, conditions and provisions of this Lease. The foregoing covenant is in lieu of any other covenant express or implied.

Section 17.18 Easements

Landlord reserves to itself the right, from time to time, to grant such easements, rights and dedications that Landlord deems necessary or desirable, and to cause the recordation of Parcel Maps and covenants, conditions and restrictions, so long as such easements, rights, dedications, Maps and covenants, conditions and restrictions do not unreasonably interfere with Tenant’s use of or access to the Premises or Tenant’s parking rights granted hereunder. Tenant shall sign any of the aforementioned or other documents, and take such other actions, which are reasonably necessary or appropriate to accomplish such granting, recordation and subordination of the Lease to same, upon request of Landlord, and failure to do so within ten (10) business days after a written request to do so shall constitute a material breach of this Lease, provided that Landlord shall reimburse Tenant for Tenant’s reasonable out-of-pocket expenses (including reasonable attorneys’ fees) necessarily incurred in the performance of Tenant’s obligations under this Section 17.18.

Section 17.19 Authority

Each individual executing this Lease on behalf of a corporation, limited liability company or partnership represents and warrants that he or she is duly authorized to execute and deliver this Lease on behalf of such entity in accordance with a duly adopted resolution of the governing group of the entity empowered to grant such authority, and that this Lease is binding upon said entity in accordance with its terms. Each party shall provide the other with a certified copy of its resolution within thirty (30) days after execution hereof, but failure to do so shall in no manner (i) be evidence of the absence of authority or (ii) affect the representation or warranty.

Section 17.20 Force Majeure Delays

In any case where either party hereto is required to do any act (other than the payment of money), and the performance of such act is prevented, delayed or stopped due to Acts of God or Nature, war, terrorism, civil commotion, fire, flood or other casualty, labor difficulties, shortages of labor or materials or equipment, government regulations, delay by government or regulatory agencies with respect to approval or permit process, unusually severe weather, the time for performance of such act (whether designated by a fixed date, a fixed time or a “reasonable time”) shall be deemed to be extended by the period of such prevention, delay or stoppage.

If Tenant does not exercise its Right of First Offer within said ten (10) business day period, then (i) Tenant shall, if Landlord desires to lease less than all of the Available Space, first have a further right to lease the smaller Available Space under this Right of First Offer, and (ii) Landlord shall thereafter be free to lease the entirety of the Available Space to anyone; provided, however, that if Landlord offers the Available Space at a rental rate which is less than ninety percent (90%) of the effective rental rate specified in the Offer Notice (taking into account differences in tenant improvement allowances and free rent periods) for a lease for the same number of years as is specified in the Offer Notice within ninety (90) days after the date on which Landlord has delivered the Offer Notice to Tenant, then Tenant’s First Offer shall again be applicable to Available Space.

(e) Conditions to Right of First Offer. Notwithstanding anything to the contrary in this Section 17.26, Landlord shall have no obligation to provide Tenant with an Offer Notice, and Tenant shall have no right to exercise Tenant’s Right of First Offer, if: (i) Tenant is in default beyond all applicable notice and cure periods either: (a) at the time Landlord seeks to lease the Available Space in question, or at the time Tenant seeks to give Landlord an Acceptance Notice, whichever, is relevant, or (b) upon the date Tenant seeks to take possession of the Available Space referenced in the Offer Notice, (ii) Tenant has assigned this Lease or sublet more than fifty percent (50%) of the rentable space located in the Premises to a party other than an Affiliate, (iii) Tenant then occupies less than fifty percent (50%) of the Premises or (iv) Tenant has received more than three (3) notices of default from Landlord during the Term of this Lease. Tenant’s Right of First Offer shall be personal to Tenant and Tenant’s Affiliate and shall not be transferable with any assignment of this Lease or subletting of the Premises.

(f) Terms for Right of First Offer. In the event that Tenant exercises Tenant’s Right of First Offer, Tenant’s occupancy of the Available Space taken shall be on all of the same terms and conditions described in the Offer Notice. In such event, Tenant’s Share due hereunder and the number of parking spaces available to Tenant shall also be adjusted accordingly.

(g) Amendment to Lease. Landlord and Tenant hereby agree to execute an amendment to this Lease (“Lease Amendment”) prior to Tenant’s occupancy of the Available Space in question. The Lease Amendment shall specify, among other things, the Rent, date of occupancy, increase in Tenant’s Share and square footage of the Available Space taken in connection with Tenant’s exercise of Tenant’s Right of First Offer. If Tenant does not execute such a Lease Amendment within fifteen (15) business days after the date on which it provides Landlord with the Acceptance Notice, then, at Landlord’s option, Tenant’s rights hereunder shall be void and terminated, but, otherwise, a valid exercise of Tenant’s Right of First Offer shall be fully effective, whether or not such amendment is executed.
