LEASE

This Lease Agreement (this “Lease”) is entered into as of June 28, 2007, between W2005 RPS REALTY, L.L.C., a Delaware limited liability company (“Landlord”), and RIVERBED TECHNOLOGY, INC., a Delaware corporation (“Tenant”).

1. Definitions and Basic Provisions. The definitions and basic provisions set forth in the Basic Lease Information (the “Basic Lease Information”) executed by Landlord and Tenant contemporaneously herewith are incorporated herein by reference for all purposes. Additionally, the following terms shall have the following meanings when used in this Lease: “Affiliate” means any person or entity which, directly or indirectly, through one or more intermediaries, controls, is controlled by, or is under common control with the party in question; “Building’s Structure” means the Building’s exterior walls, roof structure, elevator shafts, footings, foundations, structural portions of load-bearing walls, structural floors and subfloors, and structural columns and beams; “Building’s Systems” means the Building’s HVAC, life-safety, plumbing, electrical, and mechanical systems; “including” means including, without limitation; “Laws” means all federal, state, and local laws, ordinances, rules and regulations, all court orders, governmental directives, and governmental orders and all interpretations of the foregoing, and all restrictive covenants affecting the Project, and “Law” means any of the foregoing; “Tenant’s Off-Premises Equipment” means any of Tenant’s equipment or other property that may be located on or about the Project (other than inside the Premises); and “Tenant Party” means any of the following persons: Tenant; any assignees claiming by, through, or under Tenant; any subtenants claiming by, through, or under Tenant; and any of their respective agents, contractors, employees, licensees, guests and invitees.

2. Lease Grant. Subject to the terms of this Lease, Landlord leases to Tenant, and Tenant leases from Landlord, the Premises.

3. Tender of Possession. Landlord will tender possession of the Premises to Tenant in its current “as-is” condition upon full execution and delivery of this Lease. Tenant shall be deemed to have accepted the Premises in their “as-is” condition as of the date of such tender of possession and Landlord shall have no obligation to perform any work therein (including demolition of any improvements existing therein or construction of any tenant finish work or other improvements therein), and Landlord shall not be obligated to reimburse Tenant or provide an allowance for any costs related to the demolition or construction of improvements therein except as expressly provided in Exhibit D attached hereto. Promptly following the Commencement Date, Landlord and Tenant shall execute and deliver to each other a letter substantially in the form of Exhibit E hereto confirming (1) the Commencement Date and the expiration date of the initial Term, (2) that Tenant has accepted the Premises, and (3) that Landlord has performed all of its pre-Commencement Date obligations, if any, with respect to the Premises; however, the failure of the parties to execute such letter shall not defer the Commencement Date or otherwise invalidate this Lease. During Tenant’s possession of the Premises prior to the Commencement Date, Tenant shall have the right to construct tenant improvements (pursuant to the Work Letter set forth in Exhibit D), install telecommunications systems and otherwise “fit up” the Premises; provided that Tenant’s possession of the Premises prior to the Commencement Date shall be subject to all of the provisions of this Lease, except for the payment of Basic Rent and Additional Rent.

4. Rent.

(a) Payment. Tenant shall timely pay to Landlord Rent, without notice, demand, deduction or set off (except as otherwise expressly provided herein), by good and sufficient check drawn on a national banking association at Landlord’s address provided for in this Lease or as otherwise specified by Landlord and shall be accompanied by all applicable state and local sales or use taxes. The obligations of Tenant to pay Basic Rent and other sums to Landlord and the obligations of Landlord under this Lease are independent obligations. Basic Rent, adjusted as herein provided, shall be payable monthly in advance. Basic Rent for the third full calendar month of the Term shall be payable contemporaneously with the execution of this Lease; thereafter, Basic Rent shall be payable on the first day of each month beginning on the first day of the fourth full calendar month of the Term. The monthly Basic Rent for any partial month at the beginning of the Term shall equal the product of 1/365 of the annual Basic Rent in effect during the partial month and the number of days in the partial month and shall be due on the Commencement Date. Payments of Basic Rent for any fractional calendar month at the end of the Term shall be similarly prorated. Tenant shall pay Additional Rent at the same time and in the same manner as Basic Rent. This Lease shall be a net Lease and Basic Rent shall be paid to Landlord absolutely net of all costs and expenses.

(b) Operating Costs; Taxes.

(1) During each calendar year or partial calendar year of the Term, Tenant shall pay to Landlord as “Additional Rent” Tenant’s Proportionate Share of Operating Costs (defined below). Landlord may make a good faith estimate of the Additional Rent to be due by Tenant for any calendar year or part thereof during the Term and contemporaneously with the execution of this Lease, Tenant shall pay to Landlord the estimated Additional Rent for the first calendar month of the Term, and Tenant shall pay to Landlord in advance on the first day of each calendar month following the Commencement Date an amount equal to the estimated Additional Rent for such calendar year or part thereof divided by the number of months therein. From time to time, but only once during any one calendar year, Landlord may estimate and re-estimate the Additional Rent to be due by Tenant and deliver a copy of the estimate or re-estimate to Tenant. Thereafter, the monthly installments of Additional Rent payable by Tenant shall be appropriately adjusted in accordance with the estimations so that, by the end of the calendar year in question, Tenant shall have paid all of the Additional Rent as estimated by Landlord. Any amounts paid based on such an estimate shall be subject to adjustment as herein provided when actual Operating Costs are available for each calendar year.

(2) The term “Operating Costs” means all expenses and disbursements (subject to the limitations set forth below) that Landlord incurs in connection with the ownership, operation, and maintenance of the Project, determined in accordance with sound accounting principles consistently applied, including the following costs: (A) wages and salaries of all on-site employees at or below the grade of senior building manager engaged in the operation, maintenance or security of the Project (together with Landlord’s reasonable allocation of expenses of off-site employees at or below the grade of senior building manager who perform a portion of their services in connection with the operation, maintenance or security of the Project), including taxes, insurance and benefits relating thereto; (B) all supplies and materials used in the operation, maintenance, repair, replacement, and security of the Project; (C) costs for improvements made to the Project which, although capital in nature, are expected to reduce the normal operating costs (including all utility costs) of the Project, as amortized using a commercially reasonable interest rate over the time period reasonably estimated by Landlord to recover the costs thereof taking into consideration the anticipated cost savings, as determined by Landlord using its good faith, commercially reasonable judgment, as well as capital improvements made in order to comply with any Law hereafter promulgated by any governmental authority or any interpretation hereafter rendered with respect to any existing Law, as amortized using a commercially reasonable interest rate over the useful economic life of such improvements as determined by Landlord in its reasonable discretion; (D) cost of all utilities, except the cost of utilities reimbursable to Landlord by the Project’s tenants other than pursuant to a provision similar to this Section 4(b); (E) insurance expenses; (F) repairs, replacements, and general maintenance of the Project; (G) fair market rental and other costs with respect to the management office for the Project; and (H) service, maintenance and management contracts for the operation, maintenance, management, repair, replacement, or security of the Project. The Project is part of a multi-building complex (the “Complex”), and Operating Costs and Taxes for the Complex may be prorated among the Project and the other buildings of the Complex as determined by Landlord (based on a fraction, the numerator of which is the rentable square footage of the Premises and the denominator of which is the rentable square footage of the Complex, which fraction is, as of the date hereof, 9.785% based on the current rentable square footage of the Premises divided by the current rentable square footage of the Complex (which rentable square footage of the Complex is 468,323 rentable square feet as of the date hereof)), and Tenant shall pay Tenant’s Proportionate Share of the amounts so allocated. Operating Costs shall also include any costs, taxes or other charges allocated to the Project, as determined by Landlord, pursuant to or in connection with any covenants, conditions, restrictions and/or easements applicable to the Project and other property. Landlord shall collect only 100% of actual costs without ▇▇▇▇-up and Landlord shall not administer Operating Costs or Taxes as a “profit center”.

Operating Costs shall not include costs for: (i) capital improvements made to the Building, other than capital improvements described in Section 4(b)(2)(C) and except for items which are generally considered

-2-

maintenance and repair items, such as painting of common areas and the like; (ii) repair, replacements and general maintenance paid by proceeds of insurance or warranties or by Tenant or other third parties; (iii) interest, amortization or other payments on loans to Landlord; (iv) depreciation; (v) leasing commissions; (vi) legal expenses for services, other than those that benefit the Project tenants generally (e.g., tax disputes); (vii) renovating or otherwise improving space for occupants of the Project or vacant space in the Project; (viii) Taxes; (ix) federal income taxes imposed on or measured by the income of Landlord from the operation of the Project; (x) costs incurred due to violation by Landlord of the terms and conditions of any lease or any Law; (xi) overhead and profit increment paid to Landlord, its subsidiaries or affiliates for management or other services on or to the Project or for supplies or other materials to the extent that the costs of such materials, services, or supplies exceed the costs normally payable for like services, supplies or materials provided by unaffiliated parties on a competitive basis (taking into account the market factors in effect on the date any relevant contracts were negotiated) in comparable buildings; (xii) interest on debt or amortization payments (except as provided in Section 4(b)(2)(C)); (xiii) Landlord’s general corporate overhead and general administrative expenses including Landlord’s general corporate legal and accounting expenses; (xiv) cost of work required to rectify design and/or construction defects and to bring the Building into compliance with building and safety code requirements applicable to the Building as of the date hereof; (xv) marketing, advertising and promotional expenditures; (xvi) capital costs for purchasing paintings, sculpture, and other objects of art; (xvii) compensation to clerks, attendants, or to other persons involved with the operation of the parking facility or in commercial concessions operated by Landlord; (xviii) costs of abating, removing, remediating, or cleaning up (a) any asbestos or other Hazardous Materials which as of the date hereof are in violation of Hazardous Materials Laws and (b) any asbestos existing in other buildings of the Complex as of the date hereof (other than costs expended as part of the ordinary and customary operation and maintenance of the Project) except caused by Tenant or Tenant’s employees or contractors; (xiv) costs for the repair of damage to any improvements in the Project resulting from the gross negligence or willful misconduct of Landlord or Landlord’s employees and contractors; (xv) costs of insurance premiums in excess of those being charged by institutional owners of comparable buildings for comparable insurance; (xvi) charitable and political contributions; (xvii) costs associated with the operation of the business of the partnership or entity that constitutes Landlord, as the same are distinguished from the costs of operation of the Project, including partnership or other entity accounting and legal matters, costs of defending any lawsuits with any mortgagee, costs of any disputes between Landlord and its employees (if any); (xviii) interest, fines or penalties assessed as a result of Landlord’s failure to make payments in a timely manner or indemnification payments to Tenant, other occupants of the Project or third parties; (xix) costs of selling, syndicating, financing, mortgaging (including syndication thereof) or hypothecating any of Landlord’s interest in the Project; (xx) rental under any ground lease or other underlying lease of the Building or Project and other monetary obligations in connection therewith; (xxi) entertainment expenses of Landlord; (xxi) cost of leasing, purchasing or installing tenant improvements, furniture, fixtures, and equipment and operating costs of any eating facility, exercise rooms, day care center, or other specialty service, if any; (xxii) bad debt loss; and (xxiii) reserves for capital or operating costs, bad debts or Rent loss. The foregoing exclusions from Operating Costs shall apply equally to any Operating Costs or Taxes assessed in connection with the Complex.

(3) Tenant shall also pay Tenant’s Proportionate Share of Taxes for each year and partial year falling within the Term in the same manner as provided above for Tenant’s Proportionate Share of Operating Costs. “Taxes” means taxes, assessments, and governmental charges or fees whether federal, state, county or municipal, and whether they be by taxing districts or authorities presently taxing or by others, subsequently created or otherwise, and any other taxes and assessments (including non-governmental assessments for common charges under a restrictive covenant or other private agreement that are not treated as part of Operating Costs) now or hereafter attributable to the Project (or its operation), excluding, however, penalties and interest thereon and federal and state taxes on income (if the present method of taxation changes so that in lieu of or in addition to the whole or any part of any Taxes, there is levied on Landlord a capital tax directly on the rents received therefrom or a franchise tax, assessment, or charge based, in whole or in part, upon such rents for the Project, then all such taxes, assessments, or charges, or the part thereof so based, shall be deemed to be included within the term “Taxes” for purposes hereof). Taxes shall include the costs of consultants retained in an effort to lower taxes and all costs incurred in disputing any taxes or in seeking to lower the tax valuation of the Project. For property tax purposes, Tenant waives all rights to protest or appeal the appraised value of the Premises, as well as the

-3-

Project, and all rights to receive notices of reappraisement. Notwithstanding the foregoing, federal, state, and local documentary transfer taxes, gift, franchise, inheritance, transfer, succession, and estate taxes, and income taxes shall not be included as Taxes. The amount of Taxes attributable to any the calendar year shall be reduced by the amount of any refund of Taxes arising out of an appeal and permanent reduction of the Building’s, Project’s or Complex’s assessed valuation for such calendar year.

(4) By April 1 of each calendar year, or as soon thereafter as practicable but in no event later than December 31 following such April 1 date, Landlord shall furnish to Tenant a statement of Operating Costs for the previous year, in each case adjusted as provided in Section 4(b)(5), and of the Taxes for the previous year (the “Operating Costs and Tax Statement”). If Tenant’s estimated payments of Operating Costs or Taxes under this Section 4(b) for the year covered by the Operating Costs and Tax Statement exceed Tenant’s Proportionate Share of such items as indicated in the Operating Costs and Tax Statement, then Landlord shall promptly credit or reimburse Tenant for such excess; likewise, if Tenant’s estimated payments of Operating Costs or Taxes under this Section 4(b) for such year are less than Tenant’s Proportionate Share of such items as indicated in the Operating Costs and Tax Statement, then Tenant shall pay Landlord such deficiency within thirty (30) days after delivery of said notice. In the event Landlord shall not have delivered the Operating Costs and Tax Statement until after said December 31 date, Landlord shall have waived its right to collect from Tenant any underpayment for the applicable previous year as to those Operating Costs and Taxes for which Landlord has received invoices during such previous year.

(5) With respect to any calendar year or partial calendar year in which the Building is not occupied to the extent of 100% of the rentable area thereof, or Landlord is not supplying services to 100% of the rentable area thereof, the Operating Costs for such period which vary with the occupancy of the Building shall, for the purposes hereof, be increased to the amount which would have been incurred had the Building been occupied to the extent of 100% of the rentable area thereof and Landlord had been supplying services to 100% of the rentable area thereof.

(6) Provided no Event of Default then exists, after receiving an annual Operating Costs and Tax Statement and giving Landlord 30 days’ prior written notice thereof, Tenant may inspect Landlord’s records relating to Operating Costs and Taxes for the period of time covered by such Operating Costs and Tax Statement in accordance with the following provisions. If Tenant fails to object to the calculation of Operating Costs and Taxes on an annual Operating Costs and Tax Statement within 90 days after the statement has been delivered to Tenant, or if Tenant fails to conclude its inspection within 120 days after the statement has been delivered to Tenant, then Tenant shall have waived its right to object to the calculation of Operating Costs and Taxes for the year in question and the calculation of Operating Costs and Taxes set forth on such statement shall be final. Tenant’s inspection shall be conducted where Landlord maintains its books and records (which location shall be in northern California), shall not unreasonably interfere with the conduct of Landlord’s business, and shall be conducted only during business hours reasonably designated by Landlord. Tenant shall pay the cost of such inspection, unless the total Operating Costs and Taxes for the period in question is determined to be overstated by more than 5% in the aggregate, in which case Landlord shall pay the inspection cost (not to exceed the amount Tenant was overcharged for the period in question). Tenant may not conduct an inspection more than once during any calendar year. Tenant or the accounting firm conducting such inspection shall, at no charge to Landlord, submit its report in draft form to Landlord for Landlord’s review and comments before the final approved report is submitted to Landlord, and any reasonable comments by Landlord shall be incorporated into the final report. If such inspection reveals that an error was made in the Operating Costs or Taxes previously charged to Tenant, then Landlord shall refund to Tenant any overpayment of any such costs, or Tenant shall pay to Landlord any underpayment of any such costs, as the case may be, within 30 days after notification thereof. Provided Landlord’s accounting for Operating Costs and Taxes is consistent with the terms of this Lease (i.e., in accordance with sound accounting principles consistently applied), Landlord’s good faith judgment regarding the proper interpretation of this Lease and the proper accounting for Operating Costs and Taxes shall be binding on Tenant in connection with any such inspection. Tenant shall maintain the results of each such inspection confidential and shall not be permitted to use any third party to perform such inspections, other than an independent firm of certified public accountants (1) reasonably acceptable to Landlord, (2) which is not compensated on a contingency fee basis or in any other

-4-

manner which is dependent upon the results of such inspection (and Tenant shall deliver the fee agreement or other similar evidence of such fee arrangement to Landlord upon request), and (3) which agrees with Landlord in writing to maintain the results of such inspection confidential. Notwithstanding the foregoing, Tenant shall have no right to conduct an inspection if Landlord furnishes to Tenant an audit report for the period of time in question prepared by an independent certified public accounting firm of recognized national standing (whether originally prepared for Landlord or another party). Nothing in this Section 4(b)(6) shall be construed to limit, suspend or ▇▇▇▇▇ Tenant’s obligation to pay Rent when due, including Additional Rent.

5. Delinquent Payment; Handling Charges. All past due payments required of Tenant hereunder shall bear interest from the date due until paid at the lesser of eight percent (8%) per annum or the maximum lawful rate of interest (such lesser amount is referred to herein as the “Default Rate”); additionally, Landlord, in addition to all other rights and remedies available to it, may charge Tenant a fee equal to five percent of the delinquent payment to reimburse Landlord for its cost and inconvenience incurred as a consequence of Tenant’s delinquency. In no event, however, shall the charges permitted under this Section 5 or elsewhere in this Lease, to the extent they are considered to be interest under applicable Law, exceed the maximum lawful rate of interest. Notwithstanding the foregoing, the late fee referenced above shall not be charged with respect to the first occurrence (but not any subsequent occurrence) during any 12-month period that Tenant fails to make payment when due, until five days after Landlord delivers written notice of such delinquency to Tenant.

6. Letter of Credit. Concurrently with the execution of this Lease, Tenant shall deliver to Landlord, as collateral for the full and faithful performance by Tenant of all of its obligations under this Lease, an irrevocable and unconditional negotiable letter of credit (the “Letter of Credit”) containing the terms required herein, running in favor of Landlord, issued by Silicon Valley Bank or another bank reasonably approved by Landlord under the supervision of the Superintendent of Banks of the State of California, or a National Banking Association, in an amount equal to the LC Amount and otherwise satisfactory to Landlord. The Letter of Credit shall be:

(a) at sight and irrevocable;

(b) maintained in effect for the entire period from the date of execution of this Lease through the date (“LC Expiration Date”) which is thirty (30) days following the expiration of the Term of this Lease (including renewal options), provided that the expiration date thereof shall be no earlier than the LC Expiration Date or provide for automatic renewal thereof at least through the LC Expiration Date, unless the issuing bank provides at least thirty (30) days prior written notice to Landlord of such non-renewal, and Tenant shall deliver a new Letter of Credit to Landlord at least thirty (30) days prior to the expiration of the Letter of Credit without any action whatsoever on the part of Landlord;

(d) fully assignable by Landlord in connection with any number of transfers of Landlord’s interest in this Lease (with Tenant bearing any fees, costs or expenses in connection with any such transfer), and permit partial draws.

In addition to the foregoing, the form and terms of the Letter of Credit (and the bank issuing the same) shall be acceptable to Landlord, in Landlord’s reasonable discretion, and shall provide, among other things, in effect that:

(i) Landlord, or its then managing agent, shall have the right to draw down an amount up to the face amount of the Letter of Credit upon the presentation to the issuing bank of Landlord’s (or Landlord’s then managing agent’s) written statement that Landlord is entitled to make such drawing under this Lease, it being understood that if Landlord or its managing agent is a corporation, partnership or other entity, then such statement shall be signed by an officer (if a corporation), a general partner (if a partnership), or any authorized party (if another entity);

-5-

(ii) the Letter of Credit will be honored by the issuing bank without inquiry as to the accuracy thereof and regardless of whether the Tenant disputes the content of such statement; and

(iii) in the event of a transfer of Landlord’s interest in the Building, Landlord shall transfer the Letter of Credit, in whole or in part (or cause a substitute letter of credit to be delivered, as applicable) to the transferee and thereupon the Landlord shall, without any further agreement between the parties, be released by Tenant from all liability therefor, and it is agreed that the provisions hereof shall apply to every transfer or assignment of the whole or any portion of said Letter of Credit to a new landlord.

If, as a result of any application or use by Landlord of all or any part of the Letter of Credit, the amount of the Letter of Credit shall be less than the LC Amount, Tenant shall, within seven (7) business days thereafter, provide Landlord with an additional letter(s) of credit in an amount equal to the deficiency (or a replacement letter of credit in the total amount of the LC Amount) and any such additional (or replacement) letter of credit shall comply with all of the provisions of this Section 6, and if Tenant fails to comply with the foregoing, the same shall constitute an uncurable default by Tenant.

Tenant further covenants and warrants that it will neither assign nor encumber the Letter of Credit, or any part thereof and that neither Landlord nor its successors or assigns will be bound by any such assignment, encumbrance, attempted assignment or attempted encumbrance. Without limiting the generality of the foregoing, if the Letter of Credit expires earlier than the LC Expiration Date, Landlord will accept a renewal letter of credit or substitute letter of credit (such renewal or substitute letter of credit to be in effect and delivered to Landlord, as applicable, not later than thirty (30) days prior to the expiration of the Letter of Credit), which shall be irrevocable and automatically renewable as above provided through the LC Expiration Date upon the same terms as the expiring Letter of Credit or such other terms as may be acceptable to Landlord in its reasonable discretion. However, if the Letter of Credit is not timely renewed or a substitute letter of credit is not timely received, or if Tenant fails to maintain the Letter of Credit in the amount and in accordance with the terms set forth in this Section 6, Landlord shall have the right to present the Letter of Credit to the issuing bank in accordance with the terms of this Section 6, and the entire sum evidenced thereby shall be paid to and held by Landlord as cash (the “Cash Collateral”) to be held as collateral for performance of all of Tenant’s obligations under this Lease and for all losses and damages Landlord may suffer as a result of any default by Tenant under this Lease pending Tenant’s delivery to Landlord of the required replacement letter of credit in the LC Amount and otherwise complying with all of the provisions of this Section 6. Upon delivery of such replacement letter of credit, any Cash Collateral held by Landlord shall be returned to Tenant. Landlord shall have the right to hold the Cash Collateral in a deposit account in the name of Landlord and commingle the Cash Collateral with its general assets and Tenant hereby grants Landlord a security interest in the Cash Collateral. Tenant shall not be entitled to any interest earned on the Cash Collateral.

If there shall occur a default under the Lease beyond any applicable grace period, Landlord may, but without obligation to do so, draw upon the Letter of Credit and/or utilize the Cash Collateral, in part or in whole, to cure any default of Tenant and/or to compensate Landlord for any and all damages of any kind or nature sustained or which may be sustained by Landlord resulting from Tenant’s default. Tenant agrees not to interfere in any way with payment to Landlord of the proceeds of the Letter of Credit, either prior to or following a “draw” by Landlord of any portion of the Letter of Credit, regardless of whether any dispute exists between Tenant and Landlord as to Landlord’s right to draw from the Letter of Credit. No condition or term of this Lease shall be deemed to render the Letter of Credit conditional to justify the issuer of the Letter of Credit in failing to honor a drawing upon such Letter of Credit in a timely manner.

Landlord and Tenant acknowledge and agree that in no event or circumstance shall the Letter of Credit or any renewal thereof or substitute therefor or Cash Collateral be:

(a) deemed to be or treated as a “security deposit” within the meaning of California Civil Code Section 1950.7;

(b) subject to the terms of such Section 1950.7; or

-6-

The parties hereto:

(i) recite that the Letter of Credit and/or Cash Collateral, as the case may be, is not intended to serve as a security deposit and such Section 1950.7 and any and all other laws, rules and regulations applicable to security deposits in the commercial context (“Security Deposit Laws”) shall have no applicability or relevancy thereto; and

(ii) waive any and all rights, duties and obligations either party may now or, in the future, will have relating to or arising from the Security Deposit Laws.

Notwithstanding anything to the contrary contained in this Section 6, on each yearly anniversary of the Commencement Date and provided that Tenant has furnished to Landlord Tenant’s financial statements audited by a national independent certified public accounting firm for each of the four (4) most recent consecutive calendar quarters with each statement showing positive income for such quarter and provided no Event of Default exists and Tenant is not then in monetary default or material non-monetary default of any of its obligations under this Lease, Landlord shall, within ten (10) days following the later of satisfaction of the foregoing and Tenant’s written request, notify the Bank that the LC Amount may be reduced by $100,000. No such reduction may occur unless Landlord has so notified the Bank. A Letter of Credit in the LC Amount and otherwise in accordance with the terms of this Section 6 shall be required at all times, with Tenant’s non-compliance with the foregoing constituting an uncurable default under this Lease.

7. Landlord’s Obligations.

(a) Landlord’s Maintenance Obligations. This Lease is intended to be a net lease; accordingly, subject to Tenant’s payment obligations pursuant to the provisions of Section 4(b), Landlord’s maintenance obligations are limited to the repair and replacement of the Building’s Structure and any Building’s Systems not exclusively serving the Premises and maintenance and repair of the common areas of the Project. Landlord shall not be responsible for (1) any such work until Tenant notifies Landlord of the need therefor in writing, (2) alterations to the Building’s Structure required by applicable law because of alterations and improvements made by or on behalf of Tenant or the specific nature of Tenant’s use of the Premises (which alterations shall be Tenant’s responsibility), or (3) any such work that is the responsibility of Tenant pursuant to Section 8. The Building’s Structure does not include skylights, windows, glass or plate glass, doors, special fronts, or entries, all of which shall be the responsibility of Tenant. Subject to Tenant’s payment obligations pursuant to the provisions of Section 4(b), Landlord’s liability for any defects, repairs, replacement or maintenance for which Landlord is specifically responsible for under this Lease shall be limited to the cost of performing the work.

(b) Landlord’s Right to Perform Tenant’s Obligations. Landlord may perform Tenant’s maintenance, repair, and replacement obligations and any other items that are Tenant’s obligation pursuant to Section 8 in accordance with the provisions of Section 8. Tenant shall reimburse Landlord for the reasonable cost incurred in so doing within thirty (30) days after being invoiced therefor.

8. Improvements; Alterations; Repairs; Maintenance.

(a) Improvements; Alterations. Improvements to the Premises shall be installed at Tenant’s expense only in accordance with plans and specifications which have been previously submitted to and approved in writing by Landlord, which approval shall be governed by the provisions set forth in this Section 8(a). No alterations or physical additions in or to the Premises may be made without Landlord’s prior written consent, which shall not be unreasonably withheld or delayed; however, Landlord may withhold its consent to any alteration or addition that would adversely affect (in the reasonable discretion of Landlord) the (1) Building’s Structure or the Building’s Systems (including the Building’s restrooms or mechanical rooms), (2) exterior appearance of the Building, (3) appearance of the Building’s common areas, if any, or (4) provision of services to any other occupants of the Building. Landlord’s consent shall not be required for non-structural, interior cosmetic improvements costing less than $50,000 in the aggregate and not requiring a permit, provided however, at the expiration or earlier termination of this Lease, Tenant shall, at Landlord’s election, remove any such improvements and restore the Premises to its prior condition. Landlord agrees that Tenant shall not be required to remove the tenant improvements to be constructed in the Premises pursuant to Exhibit D at the expiration or earlier termination of this

-7-

Lease to the extent such improvements are consistent with general office improvements or to the extent such improvements provide supplemental HVAC or additional electricity to the labs and/or server rooms in the Premises. Tenant shall not paint or install lighting or decorations, signs, window or door lettering, or advertising media of any type visible from the exterior of the Premises without the prior written consent of Landlord, which consent may be withheld in Landlord’s sole and absolute discretion. Notwithstanding the foregoing and provided Tenant is not in default under this Lease, Tenant shall have the right, at its sole cost and expense and subject to obtaining all governmental permits and approvals therefor, to install one exterior identification sign (Building top, eyebrow or monument) at a location to be designated by Landlord, and otherwise in accordance with all Laws and the provisions of this Lease. The size, shape, content, general appearance, design, materials, coloring and lettering of said signage shall be subject to Landlord’s prior approval, which approval shall not be unreasonably withheld. Tenant shall be responsible for the fabrication, installation, maintenance and repair of such signage in good condition at Tenant’s sole cost and expense. At the expiration or earlier termination of this Lease, Tenant shall, at Tenant’s sole expense, remove Tenant’s signage and restore the Building and/or the Project to its original condition in connection with the removal of such signage. Tenant’s indemnity of Landlord under this Lease shall apply to Tenant’s signage. The signage rights granted to Tenant are personal to the original Tenant signing this Lease and any Permitted Transferee and shall not inure to the benefit of any assignee, subtenant or other occupant. All alterations, additions, and improvements shall be constructed, maintained, and used by Tenant, at its risk and expense, in accordance with all Laws; Landlord’s consent to or approval of any alterations, additions or improvements (or the plans therefor) shall not constitute a representation or warranty by Landlord, nor Landlord’s acceptance, that the same comply with sound architectural and/or engineering practices or with all applicable Laws, and Tenant shall be solely responsible for ensuring all such compliance.

(b) Repairs; Maintenance. Tenant shall maintain the Premises in a clean, safe, and operable condition, and shall not permit or allow to remain any waste or damage to any portion of the Premises. Additionally, Tenant, at its sole expense, shall repair, replace and maintain in good condition and in accordance with all Laws and the equipment manufacturer’s suggested service programs (to the extent Tenant has been advised of such service programs), all portions of the Premises, Tenant’s Off-Premises Equipment and all areas, improvements and Building’s Systems exclusively serving the Premises. Tenant shall repair or replace, subject to Landlord’s direction and supervision, any damage to the Building caused by a Tenant Party. If Tenant fails to make such repairs or replacements within 30 days after the occurrence of such damage, then Landlord may make the same at Tenant’s cost. If any such damage occurs outside of the Premises, then Landlord may elect to repair such damage at Tenant’s expense, rather than having Tenant repair such damage. The cost of all maintenance, repair or replacement work performed by Landlord under this Section 8 shall be paid by Tenant to Landlord within 30 days after Landlord has invoiced Tenant therefor. Tenant hereby waives and releases its right to make repairs at Landlord’s expense under Sections 1941 and 1942 of the California Civil Code or under any similar law, statute or ordinance now or hereafter in effect. In no event shall Tenant’s obligation to maintain the Premises in compliance with all Laws obligate Tenant to make any structural changes to the Premises (including the Building’s Systems) or in the Project, or to remove or remediate any Hazardous Materials existing in, on under or about the Premises as of the date of this Lease except in connection with Tenant’s improvements to the Premises or Tenant’s use of the Premises. Landlord and Tenant acknowledge and agree that the Premises are subject to, among other Laws, the requirements of the American with Disabilities Act, 42 U.S.C. 12101 et seq., and similar State and local Laws including, without limitation, Title 24 of the California Code of Regulations (as the same may hereafter be modified, amended or supplemented, collectively, the “ADA”). To Landlord’s knowledge, Landlord has received no written notice from any governmental authority that the Premises is currently in violation of the ADA.

(c) Performance of Work. All work described in this Section 8 shall be performed only by Landlord or by contractors and subcontractors reasonably approved in writing by Landlord. Tenant shall cause all contractors and subcontractors to procure and maintain insurance coverage naming Landlord, Landlord’s property management company and Landlord’s asset management company as additional insureds against such risks, in such amounts, and with such companies as Landlord may reasonably require. Tenant shall provide Landlord with the identities, mailing addresses and telephone numbers of all persons performing work or supplying materials prior to beginning such construction and Landlord may post on and about the Premises notices of non-responsibility pursuant to applicable Laws. All such work shall be performed in accordance with all Laws and in a good and workmanlike manner so as not to damage the Building (including the Premises, the Building’s Structure and the Building’s Systems). All such work which may affect the Building’s Structure or the Building’s Systems

-8-

must be approved by the Building’s engineer of record, at Tenant’s expense and, at Landlord’s election, must be performed by Landlord’s usual contractor for such work. All work affecting the roof of the Building must be performed by Landlord’s roofing contractor and no such work will be permitted if it would void or reduce the warranty on the roof. Notwithstanding the foregoing or any other provision of this Lease, Landlord hereby acknowledges and agrees that Tenant shall be permitted to install one additional maximum 50 ton HVAC unit on the roof of the Building and hereby consents to such installation by Tenant’s contractor provided that plans and specifications for the installation of such unit are reasonably approved by Landlord and provided such unit does not adversely affect the structural integrity of the Building or any roof warranty. Such HVAC unit shall not be removed by Tenant at the expiration or earlier termination of this Lease unless Landlord otherwise elects.

(d) Mechanic’s Liens. All work performed, materials furnished, or obligations incurred by or at the request of a Tenant Party shall be deemed authorized and ordered by Tenant only, and Tenant shall not permit any mechanic’s liens to be filed against the Premises or the Project in connection therewith. Upon completion of any such work, Tenant shall deliver to Landlord final lien waivers from all contractors, subcontractors and materialmen who performed such work. If such a lien is filed, then Tenant shall, within ten (10) days after Landlord has delivered notice of the filing thereof to Tenant (or such earlier time period as may be necessary to prevent the forfeiture of the Premises, the Project or any interest of Landlord therein or the imposition of a civil or criminal fine with respect thereto), either (1) pay the amount of the lien and cause the lien to be released of record, or (2) diligently contest such lien and deliver to Landlord a bond or other security reasonably satisfactory to Landlord. If Tenant fails to timely take either such action, then Landlord may pay the lien claim, and any amounts so paid, including expenses and interest, shall be paid by Tenant to Landlord within ten days after Landlord has invoiced Tenant therefor. Landlord and Tenant acknowledge and agree that their relationship is and shall be solely that of “landlord-tenant” (thereby excluding a relationship of “owner-contractor,” “owner-agent” or other similar relationships). Accordingly, all materialmen, contractors, artisans, mechanics, laborers and any other persons now or hereafter contracting with Tenant, any contractor or subcontractor of Tenant or any other Tenant Party for the furnishing of any labor, services, materials, supplies or equipment with respect to any portion of the Premises, at any time from the date hereof until the end of the Term, are hereby charged with notice that they look exclusively to Tenant to obtain payment for same. Landlord may record, at its election, notices of non-responsibility pursuant to California Civil Code Section 3094 in connection with any work performed by Tenant. Nothing herein shall be deemed a consent by Landlord to any liens being placed upon the Premises, the Project or Landlord’s interest therein due to any work performed by or for Tenant or deemed to give any contractor or subcontractor or materialman any right or interest in any funds held by Landlord to reimburse Tenant for any portion of the cost of such work. Tenant shall defend, indemnify and hold harmless Landlord and its agents and representatives from and against all claims, demands, causes of action, suits, judgments, damages and expenses (including attorneys’ fees) in any way arising from or relating to the failure by any Tenant Party to pay for any work performed, materials furnished, or obligations incurred by or at the request of a Tenant Party. This indemnity provision shall survive termination or expiration of this Lease.

(e) Utilities. Tenant shall pay for all water, gas, electricity, heat, telephone, sewer, sprinkler charges and other utilities and services used at the Premises, together with all taxes, penalties, surcharges, and maintenance charges pertaining thereto pursuant to the terms and conditions of this Lease. Landlord may, at Tenant’s expense, separately meter and ▇▇▇▇ Tenant directly for its use of utility services. To the extent that any particular utility is not separately metered or submetered as provided above, Landlord shall, using its good-faith, reasonable judgment, allocate the expenses for such utility among the existing tenants of the Project based upon density, usage, and other factors in Landlord’s reasonable judgment. Landlord shall not be liable for any interruption or failure of utility service to the Premises, and in no event shall the unavailability of such services or any other services (or any diminution in the quality thereof) render Landlord liable to Tenant or any entity claiming through Tenant for any damages caused thereby, constitute a constructive eviction of Tenant, constitute a breach of any implied warranty by Landlord, or entitle Tenant to any abatement of Tenant’s obligations hereunder; provided however Landlord shall use commercially reasonable diligence to restore such service or to reduce the length of such interruption, and to minimize any disturbance to Tenant, where it is within Landlord’s commercially reasonable control to do so. Additionally, if any such unavailability of such services is due to Landlord’s voluntary making of additions, alterations or improvement to the Building or the Project and Tenant is unable to conduct its business in a significant portion of the Premises for ten (10) consecutive business days as a direct result of such interruption or failure, then Tenant shall be entitled to an abatement of Basic Rent and Additional Rent for the period of such

-9-

interruption or failure which renders the Premises untenantable and during which Tenant does not use the Premises. Any amounts payable by Tenant under this Section shall be due within thirty (30) days after Landlord has invoiced Tenant therefor. Tenant shall not install any electrical equipment requiring special wiring or requiring voltage in excess of 110 volts unless approved in advance by Landlord, which approval shall not be unreasonably withheld. Tenant shall not install any electrical equipment requiring voltage in excess of Building capacity unless approved in advance by Landlord, which approval may be withheld in Landlord’s sole discretion. Landlord hereby acknowledges that Tenant has advised Landlord that certain of Tenant’s equipment uses electrical equipment requiring 208 or 220 volts and, subject to Tenant’s compliance with the provisions of this Lease, consents to such usage. The use of electricity in the Premises shall not exceed the capacity of existing feeders and risers to or wiring in the Premises. Any risers or wiring required to meet Tenant’s electrical requirements shall, upon Tenant’s written request, be installed by Landlord, at Tenant’s cost, if, in Landlord’s judgment, the same are necessary and shall not cause permanent damage to the Building or the Premises, cause or create a dangerous or hazardous condition, entail excessive or unreasonable alterations, repairs, or expenses, or interfere with or disturb any other tenants of the Building. If Tenant uses machines or equipment in the Premises which affect the temperature otherwise maintained by the air conditioning system or otherwise overload any utility, Landlord may install supplemental air conditioning units or other supplemental equipment in the Premises, and the cost thereof, including the cost of installation, operation, use, and maintenance, shall be paid by Tenant to Landlord within 30 days after Landlord has delivered to Tenant an invoice therefor.

9. Use. Tenant shall use the Premises only for the Permitted Use and shall comply with all Laws relating to the use, condition, access to, and occupancy of the Premises and will not commit waste, overload the Building’s Structure or the Building’s Systems or subject the Premises to use that would damage the Premises. The population density within the Premises shall not adversely impact the Building’s Systems. The Premises shall not be used for any use which is disreputable, creates extraordinary fire hazards, or results in an increased rate of insurance on the Building or its contents, or for the storage of any Hazardous Materials (other than typical office supplies [e.g., photocopier toner] and/or janitorial supplies, and then only in compliance with all Laws). Tenant shall not use any substantial portion of the Premises for a “call center,” any other telemarketing use, or any credit processing use. If, because of a Tenant Party’s acts or because Tenant vacates the Premises, the rate of insurance on the Building or its contents increases, then Tenant shall pay to Landlord the amount of such increase within thirty (30) days of demand therefor accompanied by documentation from the insurance company supporting the reason for such increase, and acceptance of such payment shall not waive any of Landlord’s other rights. Tenant shall conduct its business and control each other Tenant Party so as not to create any nuisance or unreasonably interfere with other tenants or Landlord in its management of the Building.

10. Assignment and Subletting.

(a) Transfers. Except as provided in Section 10(h), Tenant shall not, without the prior written consent of Landlord, (1) assign, transfer, or encumber this Lease or any estate or interest herein, whether directly or by operation of law, (2) permit any other entity to become Tenant hereunder by merger, consolidation, or other reorganization, (3) if Tenant is an entity other than a corporation whose stock is publicly traded, permit the transfer of an ownership interest in Tenant so as to result in a change in the current control of Tenant, (4) sublet any portion of the Premises, (5) grant any license, concession, or other right of occupancy of any portion of the Premises, or (6) permit the use of the Premises by any parties other than Tenant (any of the events listed in Section 10(a)(1) through 10(a)(6) being a “Transfer”).

(b) Consent Standards. Landlord shall not unreasonably withhold its consent to any assignment or subletting of the Premises, provided that the proposed transferee (1) is creditworthy, (2) has a good reputation in the business community, (3) will use the Premises for the Permitted Use (thus, excluding, without limitation, uses for credit processing and telemarketing) and will not use the Premises in any manner that would conflict with any exclusive use agreement or other similar agreement entered into by Landlord with any other tenant of the Building or Complex, (4) will not use the Premises, Building or Project in a manner that would materially increase the pedestrian or vehicular traffic to the Premises, Building or Project, (5) is not a governmental entity, or subdivision or agency thereof, (6) is not another occupant of the Building or Complex, and (7) is not a person or entity with whom Landlord is then, or has been within the six-month period prior to the time Tenant seeks to enter into such assignment or subletting, negotiating to lease space in the Building or Complex or any Affiliate of any such person or entity; otherwise, Landlord may withhold its consent in its sole discretion and, in connection

-10-

therewith, Tenant hereby waives and releases its rights under Section 1995.310 of the California Civil Code or under any similar law, statute or ordinance now or hereafter in effect. Additionally, Landlord may withhold its consent in its sole discretion to any proposed Transfer if any Event of Default by Tenant then exists.

(c) Request for Consent. If Tenant requests Landlord’s consent to a Transfer, then, at least 15 business days prior to the effective date of the proposed Transfer, Tenant shall provide Landlord with a written description of all terms and conditions of the proposed Transfer, copies of the proposed documentation, and the following information about the proposed transferee: name and address; reasonably satisfactory information about its business and business history; its proposed use of the Premises; banking, financial, and other credit information; and general references sufficient to enable Landlord to determine the proposed transferee’s creditworthiness and character. Concurrently with Tenant’s notice of any request for consent to a Transfer, Tenant shall pay to Landlord a fee of $1,000 to defray Landlord’s expenses in reviewing such request, and Tenant shall also reimburse Landlord immediately upon request for its reasonable attorneys’ fees incurred in connection with considering any request for consent to a Transfer.

(d) Conditions to Consent. If Landlord consents to a proposed Transfer, then the proposed transferee shall deliver to Landlord a written agreement whereby it expressly assumes Tenant’s obligations hereunder; however, any transferee of less than all of the space in the Premises shall be liable only for obligations under this Lease that are properly allocable to the space subject to the Transfer for the period of the Transfer. No Transfer shall release Tenant from its obligations under this Lease, but rather Tenant and its transferee shall be jointly and severally liable therefor. Landlord’s consent to any Transfer shall not waive Landlord’s rights as to any subsequent Transfers. If an Event of Default occurs while the Premises or any part thereof are subject to a Transfer, then Landlord, in addition to its other remedies, may collect directly from such transferee all rents becoming due to Tenant and apply such rents against Rent. Tenant authorizes its transferees to make payments of rent directly to Landlord upon receipt of notice from Landlord to do so following the occurrence of an Event of Default hereunder. Tenant shall pay for the cost of any demising walls or other improvements necessitated by a proposed subletting or assignment.

(e) Attornment by Subtenants. Each sublease by Tenant hereunder shall be subject and subordinate to this Lease and to the matters to which this Lease is or shall be subordinate, and each subtenant by entering into a sublease is deemed to have agreed that in the event of termination, re-entry or dispossession by Landlord under this Lease, Landlord may, at its option, take over all of the right, title and interest of Tenant, as sublandlord, under such sublease, and such subtenant shall, at Landlord’s option, attorn to Landlord pursuant to the then executory provisions of such sublease, except that Landlord shall not be (1) liable for any previous act or omission of Tenant under such sublease, (2) subject to any counterclaim, offset or defense that such subtenant might have against Tenant, (3) bound by any previous modification of such sublease not approved by Landlord in writing or by any rent or additional rent or advance rent which such subtenant might have paid for more than the current month to Tenant, and all such rent shall remain due and owing, notwithstanding such advance payment, (4) bound by any security or advance rental deposit made by such subtenant which is not delivered or paid over to Landlord and with respect to which such subtenant shall look solely to Tenant for refund or reimbursement, or (5) obligated to perform any work in the subleased space or to prepare it for occupancy, and in connection with such attornment, the subtenant shall execute and deliver to Landlord any instruments Landlord may reasonably request to evidence and confirm such attornment. Each subtenant or licensee of Tenant shall be deemed, automatically upon and as a condition of its occupying or using the Premises or any part thereof, to have agreed to be bound by the terms and conditions set forth in this Section 10(e). The provisions of this Section 10(e) shall be self-operative, and no further instrument shall be required to give effect to this provision.

(f) Cancellation. If Tenant is not then occupying at least twenty-five percent (25%) of the Premises, Landlord may, within 30 days after submission of Tenant’s written request for Landlord’s consent to an assignment or subletting, cancel this Lease as to the portion of the Premises proposed to be sublet or assigned as of the date the proposed Transfer is to be effective. If Landlord cancels this Lease as to any portion of the Premises, then this Lease shall cease for such portion of the Premises and Tenant shall pay to Landlord all Rent accrued through the cancellation date relating to the portion of the Premises covered by the proposed Transfer. Thereafter, Landlord may lease such portion of the Premises to the prospective transferee (or to any other person) without liability to Tenant.

-11-

(g) Additional Compensation. Tenant shall pay to Landlord, promptly upon receipt thereof, fifty percent (50%) of the excess of (1) all compensation received by Tenant for a Transfer less the actual out-of-pocket costs reasonably incurred by Tenant with unaffiliated third parties (i.e., brokerage commissions and tenant finish work) in connection with such Transfer (such costs shall be amortized on a straight-line basis over the term of the Transfer in question) over (2) the Rent allocable to the portion of the Premises covered thereby.

(h) Permitted Transfers. Notwithstanding Section 10(a), Tenant may Transfer all or part of its interest in this Lease or all or part of the Premises (a “Permitted Transfer”) to the following types of entities (a “Permitted Transferee”) without the written consent of Landlord, so long as (A) Tenant’s obligations hereunder are assumed by such entity; and (B) the Tangible Net Worth of such entity is not less than the Tangible Net Worth of Tenant as of the date hereof:

(1) an Affiliate of Tenant;

(2) any corporation, limited partnership, limited liability partnership, limited liability company or other business entity in which or with which Tenant, or its corporate successors or assigns, is merged or consolidated, in accordance with applicable statutory provisions governing merger and consolidation of business entities; or

(3) any corporation, limited partnership, limited liability partnership, limited liability company or other business entity acquiring all or substantially all of Tenant’s assets.

Tenant shall promptly notify Landlord of any such Permitted Transfer. Tenant shall remain liable for the performance of all of the obligations of Tenant hereunder, or if Tenant no longer exists because of a merger, consolidation, or acquisition, the surviving or acquiring entity shall expressly assume in writing the obligations of Tenant hereunder. Additionally, the Permitted Transferee shall comply with all of the terms and conditions of this Lease, including the Permitted Use, and the use of the Premises by the Permitted Transferee may not violate any other agreements affecting the Premises, the Building or the Complex, Landlord or other tenants of the Building or the Complex. No later than 30 days after the effective date of any Permitted Transfer, Tenant agrees to furnish Landlord with (A) copies of the instrument effecting any of the foregoing Transfers, (B) documentation establishing Tenant’s satisfaction of the requirements set forth above applicable to any such Transfer, and (C) evidence of insurance as required under this Lease with respect to the Permitted Transferee. The occurrence of a Permitted Transfer shall not waive Landlord’s rights as to any subsequent Transfers. “Tangible Net Worth” means the excess of total assets over total liabilities, in each case as determined in accordance with generally accepted accounting principles consistently applied (“GAAP”), excluding, however, from the determination of total assets all assets which would be classified as intangible assets under GAAP including goodwill, licenses, patents, trademarks, trade names, copyrights, and franchises. Any subsequent Transfer by a Permitted Transferee shall be subject to the terms of this Section 10.

11. Insurance; Waivers; Subrogation; Indemnity.

(a) Tenant’s Insurance. Effective as of the earlier of (1) the date Tenant enters or occupies the Premises, or (2) the Commencement Date, and continuing throughout the Term, Tenant shall maintain the following insurance policies: (A) commercial general liability insurance in amounts of $3,000,000 per occurrence or, following the expiration of the initial Term, such other amounts as Landlord may from time to time reasonably require (and, if the use and occupancy of the Premises include any activity or matter that is or may be excluded from coverage under a commercial general liability policy [e.g., the sale, service or consumption of alcoholic beverages], Tenant shall obtain such endorsements to the commercial general liability policy or otherwise obtain insurance to insure all liability arising from such activity or matter [including liquor liability, if applicable] in such amounts as Landlord may reasonably require), insuring Tenant, Landlord, Landlord’s property management company, Landlord’s asset management company and, if requested in writing by Landlord, Landlord’s Mortgagee, against all liability for injury to or death of a person or persons or damage to property arising from the use and occupancy of the Premises and (without implying any consent by Landlord to the installation thereof) the installation, operation, maintenance, repair or removal of Tenant’s Off-Premises Equipment, (B) insurance covering the full value of all alterations and improvements and betterments in the Premises, naming Landlord and Landlord’s Mortgagee as additional loss payees as their interests may appear, (C) insurance covering the full value of all furniture, trade

-12-

fixtures and personal property (including property of Tenant or others) in the Premises or otherwise placed in the Project by or on behalf of a Tenant Party (including Tenant’s Off-Premises Equipment), (D) contractual liability insurance sufficient to cover Tenant’s indemnity obligations hereunder (but only if such contractual liability insurance is not already included in Tenant’s commercial general liability insurance policy), (E) worker’s compensation insurance, and (F) business interruption insurance in an amount reasonably acceptable to Landlord. Tenant’s insurance shall provide primary coverage to Landlord when any policy issued to Landlord provides duplicate or similar coverage, and in such circumstance Landlord’s policy will be excess over Tenant’s policy. Tenant shall furnish to Landlord certificates of such insurance and such other evidence satisfactory to Landlord of the maintenance of all insurance coverages required hereunder at least ten days prior to the earlier of the Commencement Date or the date Tenant enters or occupies the Premises, and at least 15 days prior to each renewal of said insurance, and Tenant shall obtain a written obligation on the part of each insurance company to notify Landlord at least 30 days before cancellation or a material change of any such insurance policies. All such insurance policies shall be in form, and issued by companies with an A.M. Best rating of A+:VII or better, reasonably satisfactory to Landlord. If Tenant fails to comply with the foregoing insurance requirements or to deliver to Landlord the certificates or evidence of coverage required herein, Landlord, in addition to any other remedy available pursuant to this Lease or otherwise, may, but shall not be obligated to, obtain such insurance and Tenant shall pay to Landlord on demand the premium costs thereof.

(b) Landlord’s Insurance. Throughout the Term of this Lease, Landlord shall maintain, as a minimum, the following insurance policies: (1) property insurance for the Building’s replacement value (excluding property required to be insured by Tenant), less a commercially-reasonable deductible if Landlord so chooses, and (2) commercial general liability insurance in an amount of not less than $3,000,000. Landlord may, but is not obligated to, maintain such other insurance and additional coverages as it may deem necessary. The cost of all insurance carried by Landlord with respect to the Project shall be included in Operating Costs. The foregoing insurance policies and any other insurance carried by Landlord shall be for the sole benefit of Landlord and under Landlord’s sole control, and Tenant shall have no right or claim to any proceeds thereof or any other rights thereunder.

(c) No Subrogation; Waiver of Property Claims. Landlord and Tenant each waives any claim it might have against the other for any damage to or theft, destruction, loss, or loss of use of any property, to the extent the same is insured against under any insurance policy of the types described in this Section 11 that covers the Project, the Premises, Landlord’s or Tenant’s fixtures, personal property, leasehold improvements, or business, or is required to be insured against under the terms hereof, regardless of whether the negligence of the other party caused such Loss (defined below). Additionally, Tenant waives any claim it may have against Landlord for any Loss to the extent such Loss is caused by a terrorist act. Each party shall cause its insurance carrier to endorse all applicable policies waiving the carrier’s rights of recovery under subrogation or otherwise against the other party. Notwithstanding any provision in this Lease to the contrary, Landlord, its agents, employees and contractors shall not be liable to Tenant or to any party claiming by, through or under Tenant for (and Tenant hereby releases Landlord and its servants, agents, contractors, employees and invitees from any claim or responsibility for) any damage to or destruction, loss, or loss of use, or theft of any property of any Tenant Party located in or about the Project, caused by casualty, theft, fire, third parties or any other matter or cause, regardless of whether the negligence of any party caused such loss in whole or in part. Tenant acknowledges that Landlord shall not carry insurance on, and shall not be responsible for damage to, any property of any Tenant Party located in or about the Project.

(d) Indemnity. Subject to Section 11(c), Tenant shall defend, indemnify, and hold harmless Landlord and its representatives and agents from and against all claims, demands, liabilities, causes of action, suits, judgments, damages, and expenses (including reasonable attorneys’ fees) arising from any injury to or death of any person or the damage to or theft, destruction, loss, or loss of use of, any property or inconvenience (a “Loss”) (1) occurring in or on the Project (other than within the Premises) to the extent caused by the negligence or willful misconduct of any Tenant Parties, (2) occurring in the Premises, or (3) arising out of the installation, operation, maintenance, repair or removal of any property of any Tenant Party located in or about the Project, including Tenant’s Off-Premises Equipment. It being agreed that clauses (2) and (3) of this indemnity are not intended to indemnify Landlord and its agents, employees, contractors and representatives to the extent of their own negligence or willful misconduct unless covered by the insurance maintained by Tenant or required to be maintained by Tenant under this Lease. Subject to Section 11(c), Landlord shall defend, indemnify and hold harmless Tenant and its

-13-

agents from and against all claims, demands, liabilities, causes of action, suits, judgments, damages, and expenses (including reasonable attorneys’ fees) for any Loss arising from any occurrence in the common areas of the Project to the extent caused by the negligence or willful misconduct of Landlord, its employees, contractors, agents or representatives. The indemnities set forth in this Lease shall survive termination or expiration of this Lease and shall not terminate or be waived, diminished or affected in any manner by any abatement or apportionment of Rent under any provision of this Lease. If any proceeding is filed for which indemnity is required hereunder, the indemnifying party agrees, upon request therefor, to defend the indemnified party in such proceeding at its sole cost utilizing counsel satisfactory to the indemnified party.

12. Subordination; Attornment; Notice to Landlord’s Mortgagee.

(a) Subordination. This Lease shall be subordinate to any deed of trust, mortgage, or other security instrument (each, a “Mortgage”), or any ground lease, master lease, or primary lease (each, a “Primary Lease”), that now or hereafter covers all or any part of the Premises (the mortgagee under any such Mortgage, beneficiary under any such deed of trust, or the lessor under any such Primary Lease is referred to herein as a “Landlord’s Mortgagee”). Any Landlord’s Mortgagee may elect, at any time, unilaterally, to make this Lease superior to its Mortgage, Primary Lease, or other interest in the Premises by so notifying Tenant in writing. The provisions of this Section shall be self-operative and no further instrument of subordination shall be required; however, in confirmation of such subordination, Tenant shall execute and return to Landlord (or such other party designated by Landlord) within ten days after written request therefor such documentation (including a subordination, non-disturbance and attornment agreement), in recordable form if required, as a Landlord’s Mortgagee may reasonably request to evidence (i) the subordination of this Lease to such Landlord’s Mortgagee’s Mortgage or Primary Lease, provided that any such documentation shall include Landlord’s Mortgagee’s standard non-disturbance language or (ii) if the Landlord’s Mortgagee so elects, the subordination of such Landlord’s Mortgagee’s Mortgage or Primary Lease to this Lease. Landlord agrees to use commercially reasonable efforts to obtain a subordination, non-disturbance and attornment agreement from any existing Landlord’s Mortgagee on Landlord’s Mortgagee’s standard form within sixty (60) days following the date of this Lease.

(b) Attornment. Tenant shall attorn to any party succeeding to Landlord’s interest in the Premises, whether by purchase, foreclosure, deed in lieu of foreclosure, power of sale, termination of lease, or otherwise, upon such party’s request, and shall execute such agreements confirming such attornment as such party may reasonably request.

(c) Notice to Landlord’s Mortgagee. Tenant shall not seek to enforce any remedy it may have for any default on the part of Landlord without first giving written notice by certified mail, return receipt requested or by overnight nationally recognized courier service, specifying the default in reasonable detail, to any Landlord’s Mortgagee whose address has been given to Tenant, and affording such Landlord’s Mortgagee a reasonable opportunity to perform Landlord’s obligations hereunder.

(d) Landlord’s Mortgagee’s Protection Provisions. If Landlord’s Mortgagee shall succeed to the interest of Landlord under this Lease, Landlord’s Mortgagee shall not be: (1) liable for any act or omission of any prior lessor (including Landlord); (2) bound by any rent or additional rent or advance rent which Tenant might have paid for more than the current month to any prior lessor (including Landlord), and all such rent shall remain due and owing, notwithstanding such advance payment; (3) bound by any security or advance rental deposit made by Tenant which is not delivered or paid over to Landlord’s Mortgagee and with respect to which Tenant shall look solely to Landlord for refund or reimbursement; (4) bound by any termination, amendment or modification of this Lease made without Landlord’s Mortgagee’s consent and written approval, except for those terminations, amendments and modifications permitted to be made by Landlord without Landlord’s Mortgagee’s consent pursuant to the terms of the loan documents between Landlord and Landlord’s Mortgagee; (5) subject to the defenses which Tenant might have against any prior lessor (including Landlord); and (6) subject to the offsets which Tenant might have against any prior lessor (including Landlord) except for those offset rights which (A) are expressly provided in this Lease, (B) relate to periods of time following the acquisition of the Building by Landlord’s Mortgagee, and (C) Tenant has provided written notice to Landlord’s Mortgagee and provided Landlord’s Mortgagee a reasonable opportunity to cure the event giving rise to such offset event. Landlord’s Mortgagee shall have no liability or responsibility under or pursuant to the terms of this Lease or otherwise after it ceases to own an interest in the Project. Nothing in this Lease shall be construed to require Landlord’s Mortgagee to see to the application of the proceeds of any loan, and Tenant’s agreements set forth herein shall not be impaired on account of any modification of the documents evidencing and securing any loan.

-14-

13. Rules and Regulations. Tenant shall comply with the rules and regulations of the Project which are attached hereto as Exhibit C. Landlord may, from time to time, change such rules and regulations for the safety, care, or cleanliness of the Project and related facilities, provided that such changes are applicable to all tenants of the Project, will not unreasonably interfere with Tenant’s use of the Premises and are enforced by Landlord in a non-discriminatory manner. Tenant shall be responsible for the compliance with such rules and regulations by each Tenant Party.

14. Condemnation.

(a) Total Taking. If the entire Building or Premises are taken by right of eminent domain or conveyed in lieu thereof (a “Taking“), this Lease shall terminate as of the date of the Taking.

(b) Partial Taking—Tenant’s Rights. If any part of the Building becomes subject to a Taking and such Taking will prevent Tenant from conducting on a permanent basis its business in the Premises in a manner reasonably comparable to that conducted immediately before such Taking, then Tenant may terminate this Lease as of the date of such Taking by giving written notice to Landlord within 30 days after the Taking, and Basic Rent and Additional Rent shall be apportioned as of the date of such Taking. If Tenant does not terminate this Lease, then Rent shall be abated on a reasonable basis as to that portion of the Premises rendered untenantable by the Taking.

(c) Partial Taking—Landlord’s Rights. If any material portion, but less than all, of the Building becomes subject to a Taking, or if Landlord is required to pay any of the proceeds arising from a Taking to a Landlord’s Mortgagee, then Landlord may terminate this Lease by delivering written notice thereof to Tenant within 30 days after such Taking, and Basic Rent and Additional Rent shall be apportioned as of the date of such Taking. If Landlord does not so terminate this Lease, then this Lease will continue, but if any portion of the Premises has been taken, Rent shall ▇▇▇▇▇ as provided in the last sentence of Section 14(b). Tenant hereby waives any and all rights it might otherwise have pursuant to Section 1265.130 of the California Code of Civil Procedures.

(d) Temporary Taking. If all or any portion of the Premises becomes subject to a Taking for a limited period of time, this Lease shall remain in full force and effect and Tenant shall continue to perform all of the terms, conditions and covenants of this Lease, including the payment of Basic Rent and all other amounts required hereunder, provided that Tenant shall have the right to terminate this Lease if the temporary Taking (a) extends beyond 180 days or (b) is still in effect 180 days prior to the expiration date of this Lease. If any such temporary Taking terminates prior to the expiration of the Term, Tenant shall have no obligation to remove any alterations made by or on behalf of the condemning governmental authority nor to restore the Premises to the condition existing prior to such temporary Taking. Landlord shall be entitled to receive the entire award for any such temporary Taking, except that Tenant shall be entitled to receive the portion of such award which compensates Tenant for its loss of use of the Premises within the Term.

(e) Award. If any Taking occurs, then Landlord shall receive the entire award or other compensation for the Land, the Building, and other improvements taken; however, Tenant may separately pursue a claim (to the extent it will not reduce Landlord’s award) against the condemnor for the value of Tenant’s personal property which Tenant is entitled to remove under this Lease, moving costs and loss of business.

15. Fire or Other Casualty.

(a) Repair Estimate. If the Premises or the Building are damaged by fire or other casualty (a “Casualty”), Landlord shall, within 90 days after such Casualty, deliver to Tenant a good faith estimate (the “Damage Notice”) of the time needed to repair the damage caused by such Casualty.

(b) Tenant’s Rights. If a material portion of the Premises is damaged by Casualty such that Tenant is prevented from conducting its business in the Premises in a manner reasonably comparable to that

-15-

conducted immediately before such Casualty and Landlord estimates that the damage caused thereby cannot be repaired within 270 days after the commencement of repairs (the “Repair Period”), then Tenant may terminate this Lease by delivering written notice to Landlord of its election to terminate within 30 days after the Damage Notice has been delivered to Tenant.

(c) Landlord’s Rights. If a Casualty damages the Premises or a material portion of the Building and (1) Landlord estimates that the damage to the Premises cannot be repaired within the Repair Period, (2) the damage to the Premises exceeds 50% of the replacement cost thereof (excluding foundations and footings), as estimated by Landlord, and such damage occurs during the last year of the Term and no renewal rights have been exercised prior to such Casualty, (3) regardless of the extent of damage to the Premises, the damage is not fully covered by Landlord’s insurance policies or Landlord makes a good faith commercially reasonable determination that restoring the Building would be uneconomical, or (4) Landlord is required to pay any insurance proceeds arising out of the Casualty to a Landlord’s Mortgagee, then Landlord may terminate this Lease by giving written notice of its election to terminate within 30 days after the Damage Notice has been delivered to Tenant.

(d) Repair Obligation. If neither party elects to terminate this Lease following a Casualty, then Landlord shall, within a reasonable time after such Casualty (but in all events within the Repair Period), begin to repair the Premises and shall proceed with reasonable diligence to restore the Premises to substantially the same condition as they existed immediately before such Casualty; however, Landlord shall not be required to repair or replace any alterations or betterments within the Premises (which shall be promptly and with due diligence repaired and restored by Tenant at Tenant’s sole cost and expense) or any furniture, equipment, trade fixtures or personal property of Tenant or others in the Premises or the Building.

(e) Waiver of Statutory Provisions. The provisions of this Lease, including this Section 15, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises or the Building and any statute or regulation of the State of California, including, without limitation, Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or obligations concerning damage or destruction in the absence of an express agreement between the parties, and any other statute or regulation, now or hereafter in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises or the Building.

(f) Abatement of Rent. If the Premises are damaged by Casualty, Rent for the portion of the Premises rendered untenantable by the damage shall be abated on a reasonable basis from the date of damage until the completion of Landlord’s repairs (or until the date of termination of this Lease by Landlord or Tenant as provided above, as the case may be), unless a Tenant Party caused such damage, in which case, Tenant shall continue to pay Rent without abatement except to the extent of insurance proceeds received by Landlord for such abated rent.

16. Personal Property Taxes. Tenant shall be liable for all taxes levied or assessed against personal property, furniture, or fixtures placed by Tenant in the Premises or in or on the Building or Project. If any taxes for which Tenant is liable are levied or assessed against Landlord or Landlord’s property and Landlord elects to pay the same, or if the assessed value of Landlord’s property is increased by inclusion of such personal property, furniture or fixtures and Landlord elects to pay the taxes based on such increase, then Tenant shall pay to Landlord, within 30 days following written request therefor, the part of such taxes for which Tenant is primarily liable hereunder; however, Landlord shall not pay such amount if Tenant notifies Landlord that it will contest the validity or amount of such taxes before Landlord makes such payment, and thereafter diligently proceeds with such contest in accordance with Law and if the non-payment thereof does not pose a threat of loss or seizure of the Project or interest of Landlord therein or impose any fee or penalty against Landlord.

17. Events of Default. Each of the following occurrences shall be an “Event of Default”:

(a) Payment Default. Tenant’s failure to pay Rent within five (5) business days after Landlord has delivered written notice to Tenant that the same is due (any such notice shall be in lieu of, and not in addition to, any notice required under California Code of Civil Procedure Section 1161 or any similar or successor law); however, an Event of Default shall occur hereunder without any obligation of Landlord to give any notice if Tenant fails to pay Rent when due and, during the 12-month interval preceding such failure, Landlord has given Tenant written notice of failure to pay Rent on one or more occasions;

-16-

(b) Abandonment. Tenant abandons the Premises, as the term abandonment is defined in California Civil Code Section 1951.3;

(c) Estoppel. Tenant fails to provide any estoppel certificate after Landlord’s written request therefor pursuant to Section 25(e) and such failure shall continue for five days after Landlord’s second written notice thereof to Tenant;

(d) Insurance. Tenant fails to procure, maintain and deliver to Landlord evidence of the insurance policies and coverages as required under Section 11(a), and such failure continues for ten (10) days following written notice from Landlord;

(e) Mechanic’s Liens. Tenant fails to pay and release of record, or diligently contest and bond around, any mechanic’s lien filed against the Premises or the Project for any work performed, materials furnished, or obligation incurred by or at the request of Tenant, within the time and in the manner required by Section 8(d);

(f) Other Defaults. Tenant’s failure to perform, comply with, or observe any other agreement or obligation of Tenant under this Lease and the continuance of such failure for a period of more than 30 days after Landlord has delivered to Tenant written notice thereof (any such notice shall be in lieu of, and not in addition to, any notice required under California Code of Civil Procedure Section 1161 or any similar or successor law), provided if the nature of such breach cannot be cured within such 30 day period, then Tenant shall not be deemed to be in default if Tenant commences such cure within such 30 day period and thereafter diligently prosecutes such cure to completion; and

(g) Insolvency. The filing of a petition by or against Tenant (the term “Tenant” shall include, for the purpose of this Section 17(g), any guarantor of Tenant’s obligations hereunder) (1) in any bankruptcy or other insolvency proceeding; (2) seeking any relief under any state or federal debtor relief law; (3) for the appointment of a liquidator or receiver for all or substantially all of Tenant’s property or for Tenant’s interest in this Lease; (4) for the reorganization or modification of Tenant’s capital structure; or (5) in any assignment for the benefit of creditors proceeding; however, if such a petition is filed against Tenant, then such filing shall not be an Event of Default unless Tenant fails to have the proceedings initiated by such petition dismissed within 90 days after the filing thereof.

18. Remedies. Upon any Event of Default, Landlord may, in addition to all other rights and remedies afforded Landlord hereunder or by law or equity, take any one or more of the following actions, each and all of which shall be cumulative and non-exclusive, without notice or demand whatsoever:

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

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

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

-17-

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

(4) Any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result therefrom, specifically including but not limited to, brokerage commissions and advertising expenses incurred, expenses of remodeling the Premises or any portion thereof for a new tenant, whether for the same or a different use, and any special concessions made to obtain a new tenant; and

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

The term “Rent” as used in this Section 18(a) shall be deemed to be and to mean all sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or to others. As used in Section 18(a)(1) and 18(a)(2) above, the “worth at the time of award” shall be computed by allowing interest at the Interest Rate set forth in Section 5 of this Lease, but in no case greater than the maximum amount of such interest permitted by Law. As used in Section 18(a)(3) above, the “worth at the time of award” shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one percent (1%).

(b) Enforcement of Lease. Landlord shall have the remedy described in California Civil Code Section 1951.4 (lessor may continue lease in effect after lessee’s breach and abandonment and recover rent as it becomes due, if lessee has the right to sublet or assign, subject only to reasonable limitations). Accordingly, Landlord may, from time to time, without terminating this Lease, enforce all of its rights and remedies under this Lease, including the right to recover all rent as it becomes due.

(c) Sublessees of Tenant. Whether or not Landlord elects to terminate this Lease on account of any Event of Default by Tenant, as set forth in this Section 18, Landlord shall have the right to terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises or may, in Landlord’s sole discretion, succeed to Tenant’s interest in such subleases, licenses, concessions or arrangements. In the event of Landlord’s election to succeed to Tenant’s interest in any such subleases, licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder.

(d) Efforts to Relet. For the purposes of this Section 18, Tenant’s right to possession shall not be deemed to have been terminated by efforts of Landlord to relet the Premises, by its acts of maintenance or preservation with respect to the Premises, or by appointment of a receiver to protect Landlord’s interests hereunder. The foregoing enumeration is not exhaustive, but merely illustrative of acts which may be performed by Landlord without terminating Tenant’s right to possession.

19. Payment by Tenant; Non-Waiver; Cumulative Remedies.

(a) Payment by Tenant. Upon any Event of Default, Tenant shall pay to Landlord all costs incurred by Landlord (including court costs and reasonable attorneys’ fees and expenses) in (1) obtaining possession of the Premises, (2) removing and storing Tenant’s or any other occupant’s property, (3) repairing, restoring, altering, remodeling, or otherwise putting the Premises into condition acceptable to a new tenant, (4) performing Tenant’s obligations which Tenant failed to perform, and (5) enforcing, or advising Landlord of, its rights, remedies, and recourses arising out of the default. To the full extent permitted by law, Landlord and Tenant agree the federal and state courts of the state in which the Premises are located shall have exclusive jurisdiction over any matter relating to or arising from this Lease and the parties’ rights and obligations under this Lease.

(b) No Waiver. Landlord’s acceptance of Rent following an Event of Default shall not waive Landlord’s rights regarding such Event of Default. No waiver by Landlord of any violation or breach of any

-18-

of the terms contained herein shall waive Landlord’s rights regarding any future violation of such term. Landlord’s acceptance of any partial payment of Rent shall not waive Landlord’s rights with regard to the remaining portion of the Rent that is due, regardless of any endorsement or other statement on any instrument delivered in payment of Rent or any writing delivered in connection therewith; accordingly, Landlord’s acceptance of a partial payment of Rent shall not constitute an accord and satisfaction of the full amount of the Rent that is due.

(c) Cumulative Remedies. Any and all remedies set forth in this Lease: (1) shall be in addition to any and all other remedies Landlord may have at law or in equity, (2) shall be cumulative, and (3) may be pursued successively or concurrently as Landlord may elect. The exercise of any remedy by Landlord shall not be deemed an election of remedies or preclude Landlord from exercising any other remedies in the future. Additionally, Tenant shall defend, indemnify and hold harmless Landlord, Landlord’s Mortgagee and their respective representatives and agents from and against all claims, demands, liabilities, causes of action, suits, judgments, damages and expenses (including reasonable attorneys’ fees) arising from Tenant’s failure to perform its obligations under this Lease.

20. Intentionally Omitted.

21. Surrender of Premises. No act by Landlord shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept a surrender of the Premises shall be valid unless it is in writing and signed by Landlord. At the expiration or termination of this Lease, Tenant shall deliver to Landlord the Premises with all improvements located therein in good repair and condition, free of Hazardous Materials placed on the Premises during the Term, broom-clean, reasonable wear and tear (and condemnation and Casualty damage not caused by Tenant, as to which Sections 14 and 15 shall control) excepted, and shall deliver to Landlord all keys to the Premises. Tenant shall remove all unattached trade fixtures, furniture, and personal property placed in the Premises or elsewhere in the Building by Tenant (but Tenant may not remove any such item which was paid for, in whole or in part, by Landlord or any wiring or cabling unless Landlord requires such removal). Additionally, at Landlord’s option, Tenant shall remove such alterations, additions, improvements, wiring, conduits and cabling (including Tenant’s Off-Premises Equipment) as Landlord may request; however, Tenant shall not be required to remove any addition or improvement to the Premises or the Project if Landlord has specifically agreed in writing that the improvement or addition in question need not be removed. Landlord hereby agrees that Tenant shall not be required to remove any of the tenant improvements constructed in the Premises pursuant to Exhibit D to the extent such improvements are consistent with general office improvements. Tenant shall repair all damage caused by such removal. All items not so removed shall, at Landlord’s option, be deemed to have been abandoned by Tenant and may be appropriated, sold, stored, destroyed, or otherwise disposed of by Landlord without notice to Tenant and without any obligation to account for such items. The provisions of this Section 21 shall survive the end of the Term.

22. Holding Over. If Tenant fails to vacate the Premises at the end of the Term, then Tenant shall be a tenant at sufferance and, in addition to all other damages and remedies to which Landlord may be entitled for such holding over, (a) Tenant shall pay, in addition to the other Rent, Basic Rent equal to 125% of the Rent payable during the last month of the Term for the first month of holdover and 150% of the Rent payable during the last month of the Term for the second month and any additional months of such holdover, and (b) Tenant shall otherwise continue to be subject to all of Tenant’s obligations under this Lease. The provisions of this Section 22 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. If Tenant fails to surrender the Premises upon the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from all loss, costs (including reasonable attorneys’ fees) and liability resulting from such failure, including any claims made by any succeeding tenant founded upon such failure to surrender, and any lost profits to Landlord resulting therefrom. Following Tenant’s written request, Landlord shall notify Tenant whether the Premises have been re-rented.

23. Certain Rights Reserved by Landlord. Provided that the exercise of such rights does not unreasonably interfere with Tenant’s occupancy of the Premises, Landlord shall have the following rights:

(a) Building Operations. To decorate and to make inspections, repairs, alterations, additions, changes, or improvements, whether structural or otherwise, in and about the Project and Complex, or any

-19-

part thereof; to enter upon the Premises (after giving Tenant reasonable notice thereof, which may be oral notice, except in cases of real or apparent emergency, in which case no notice shall be required) and, during the continuance of any such work, to temporarily close doors, entryways, public space, and corridors in the Building; to interrupt or temporarily suspend Building services and facilities; to change the name of the Building and/or Complex; and to change the arrangement and location of entrances or passageways, doors, and doorways, corridors, elevators, stairs, restrooms, or other public parts of the Building;

(b) Security. To take such reasonable measures as Landlord deems advisable for the security of the Building and its occupants; evacuating the Building for cause, suspected cause, or for drill purposes; temporarily denying access to the Building; and closing the Building after normal business hours and on Sundays and holidays, subject, however, to Tenant’s right to enter when the Building is closed after normal business hours under such reasonable regulations as Landlord may prescribe from time to time;

(c) Prospective Purchasers and Lenders. To enter the Premises at all reasonable hours to show the Premises to prospective purchasers or lenders; and

(d) Prospective Tenants. At any time during the last 12 months of the Term or at any time following the occurrence of an Event of Default, to enter the Premises at all reasonable hours to show the Premises to prospective tenants.

24. Intentionally Omitted.

25. Miscellaneous.

(a) Landlord Transfer. Landlord may transfer any portion of the Project and any of its rights under this Lease. If Landlord assigns its rights under this Lease, then Landlord shall thereby be released from any further obligations hereunder arising after the date of transfer, provided that the assignee assumes in writing Landlord’s obligations hereunder arising from and after the transfer date.

(b) Landlord’s Liability. The liability of Landlord (and its partners, shareholders or members) to Tenant (or any person or entity claiming by, through or under Tenant) for any default by Landlord under the terms of this Lease or any matter relating to or arising out of the occupancy or use of the Premises and/or other areas of the Building shall be limited to Tenant’s actual direct, but not consequential, damages therefor and shall be recoverable only from the interest of Landlord in the Building, and Landlord (and its partners, shareholders or members) shall not be personally liable for any deficiency.

(c) Force Majeure. Other than for Tenant’s obligations under this Lease that can be performed by the payment of money (e.g., payment of Rent and maintenance of insurance), whenever a period of time is herein prescribed for action to be taken by either party hereto, such party shall not be liable or responsible for, and there shall be excluded from the computation of any such period of time, any delays due to strikes, riots, acts of God, shortages of labor or materials, war, terrorist acts or activities, governmental laws, regulations, or restrictions, or any other causes of any kind whatsoever which are beyond the control of such party.

(d) Brokerage. Neither Landlord nor Tenant has dealt with any broker or agent in connection with the negotiation or execution of this Lease, other than CB ▇▇▇▇▇▇▇ ▇▇▇▇▇, who represents Landlord, and NAIBT Commercial, who represents Tenant, and whose commissions shall be paid by Landlord pursuant to a separate written agreement.

(e) Estoppel Certificates. From time to time, Tenant shall furnish to any party designated by Landlord, within ten (10) business days after Landlord has made a request therefor, a certificate signed by Tenant confirming and containing such factual certifications and representations as to this Lease as Landlord may reasonably request. Unless otherwise required by Landlord’s Mortgagee or a prospective purchaser or mortgagee of the Project, the initial form of estoppel certificate to be signed by Tenant is attached hereto as Exhibit F. If Tenant

-20-

fails to respond within such ten (10) business day period, and Landlord gives Tenant a second notice, then if Tenant fails to deliver to Landlord the certificate signed by Tenant within five (5) days after such second notice, Landlord, Landlord’s Mortgagee and any prospective purchaser or mortgagee, may conclusively presume and rely upon the following facts: (1) this Lease is in full force and effect; (2) the terms and provisions of this Lease have not been changed except as otherwise represented by Landlord; (3) not more than one monthly installment of Basic Rent and other charges have been paid in advance; (4) there are no claims against Landlord nor any defenses or rights of offset against collection of Rent or other charges; and (5) to Tenant’s actual knowledge, Landlord is not in default under this Lease. In such event, Tenant shall be estopped from denying the truth of the presumed facts.

(f) Notices. All notices and other communications given pursuant to this Lease shall be in writing and shall be (1) mailed by first class, United States Mail, postage prepaid, certified, with return receipt requested, and addressed to the parties hereto at the address specified in the Basic Lease Information, (2) hand delivered to the intended addressee, (3) sent by a nationally recognized overnight courier service, or (4) sent by facsimile transmission during normal business hours followed by a confirmatory letter sent in another manner permitted hereunder. All notices shall be effective upon delivery to the address of the addressee (even if such addressee refuses delivery thereof). The parties hereto may change their addresses by giving notice thereof to the other in conformity with this provision.

(g) Separability. If any clause or provision of this Lease is illegal, invalid, or unenforceable under present or future laws, then the remainder of this Lease shall not be affected thereby and in lieu of such clause or provision, there shall be added as a part of this Lease a clause or provision as similar in terms to such illegal, invalid, or unenforceable clause or provision as may be possible and be legal, valid, and enforceable.

(h) Amendments; Binding Effect; No Electronic Records. This Lease may not be amended except by instrument in writing signed by Landlord and Tenant. No provision of this Lease shall be deemed to have been waived by Landlord unless such waiver is in writing signed by Landlord, and no custom or practice which may evolve between the parties in the administration of the terms hereof shall waive or diminish the right of Landlord to insist upon the performance by Tenant in strict accordance with the terms hereof. All notices and other communications shall be given in the manner specifically set forth in Section 25(f). The terms and conditions contained in this Lease shall inure to the benefit of and be binding upon the parties hereto, and upon their respective successors in interest and legal representatives, except as otherwise herein expressly provided. This Lease is for the sole benefit of Landlord and Tenant, and, other than Landlord’s Mortgagee, no third party shall be deemed a third party beneficiary hereof.

(i) Quiet Enjoyment. Provided Tenant has performed all of its obligations hereunder, Tenant shall peaceably and quietly hold and enjoy the Premises for the Term, without hindrance from Landlord or any party claiming by, through, or under Landlord, but not otherwise, subject to the terms and conditions of this Lease.

(j) No Merger. There shall be no merger of the leasehold estate hereby created with the fee estate in the Premises or any part thereof if the same person acquires or holds, directly or indirectly, this Lease or any interest in this Lease and the fee estate in the leasehold Premises or any interest in such fee estate.

(k) No Offer. The submission of this Lease to Tenant shall not be construed as an offer, and Tenant shall not have any rights under this Lease unless Landlord executes a copy of this Lease and delivers it to Tenant.

(l) Entire Agreement. This Lease constitutes the entire agreement between Landlord and Tenant regarding the subject matter hereof and supersedes all oral statements and prior writings relating thereto. Except for those set forth in this Lease, no representations, warranties, or agreements have been made by Landlord or Tenant to the other with respect to this Lease or the obligations of Landlord or Tenant in connection therewith. The normal rule of construction that any ambiguities be resolved against the drafting party shall not apply to the interpretation of this Lease or any exhibits or amendments hereto.

(m) Waiver of Jury Trial. TO THE MAXIMUM EXTENT PERMITTED BY LAW, LANDLORD AND TENANT EACH WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY LITIGATION

-21-

OR TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE ARISING OUT OF OR WITH RESPECT TO THIS LEASE OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS RELATED HERETO.

(n) Governing Law. This Lease shall be governed by and construed in accordance with the laws of the state in which the Premises are located.

(o) Recording. Tenant shall not record this Lease or any memorandum of this Lease without the prior written consent of Landlord, which consent may be withheld or denied in the sole and absolute discretion of Landlord, and any recordation by Tenant shall be a material breach of this Lease. Tenant grants to Landlord a power of attorney to execute and record a release releasing any such recorded instrument of record that was recorded without the prior written consent of Landlord.

(p) Water or Mold Notification. To the extent Tenant or its agents or employees discover any water leakage, water damage or mold in or about the Premises or Project, Tenant shall promptly notify Landlord thereof in writing.

(q) Joint and Several Liability. If Tenant is comprised of more than one party, each such party shall be jointly and severally liable for Tenant’s obligations under this Lease. All unperformed obligations of Tenant hereunder not fully performed at the end of the Term shall survive the end of the Term, including payment obligations with respect to Rent and all obligations concerning the condition and repair of the Premises.

(r) Financial Reports. Within 15 days after Landlord’s request, Tenant will furnish Tenant’s most recent audited financial statements (including any notes to them) to Landlord, or, if no such audited statements have been prepared, such other financial statements (and notes to them) as may have been prepared by an independent certified public accountant or, failing those, Tenant’s internally prepared financial statements. If Tenant is a publicly traded corporation, Tenant may satisfy its obligations hereunder by providing to Landlord Tenant’s most recent annual and quarterly reports. Tenant will discuss its financial statements with Landlord and, following the occurrence of an Event of Default hereunder, will give Landlord access to Tenant’s books and records in order to enable Landlord to verify the financial statements. Landlord will not disclose any aspect of Tenant’s financial statements that Tenant designates to Landlord as confidential except (1) to Landlord’s Mortgagee or prospective mortgagees or purchasers of the Building, (2) in litigation between Landlord and Tenant, and/or (3) if required by court order. Tenant shall not be required to deliver the financial statements required under this Section 25(r) more than once in any 12-month period unless requested by Landlord’s Mortgagee or a prospective buyer or lender of the Building or an Event of Default occurs.

(s) Landlord’s Fees. Whenever Tenant requests Landlord to take any action not required of it hereunder or give any consent required or permitted under this Lease, Tenant will reimburse Landlord for Landlord’s reasonable, out-of-pocket costs payable to third parties and incurred by Landlord in reviewing the proposed action or consent, including reasonable attorneys’, engineers’ or architects’ fees, within 30 days after Landlord’s delivery to Tenant of a statement of such costs. Tenant will be obligated to make such reimbursement without regard to whether Landlord consents to any such proposed action.

(t) Attorneys’ Fees. In the event that either Landlord or Tenant should bring suit for the possession of the Premises, for the recovery of any sum due under this Lease, or because of the breach of any provision of this Lease or for any other relief against the other, then all costs and expenses, including reasonable attorneys’ fees, incurred by the prevailing party therein, shall be paid by the other party, which obligation on the part of the other party shall be deemed to have accrued on the date of the commencement of such action and shall be enforceable whether or not the action is prosecuted to judgment.

(u) Telecommunications. Tenant and its telecommunications companies, including local exchange telecommunications companies and alternative access vendor services companies, shall have no right of access to and within the Building, for the installation and operation of telecommunications systems, including voice, video, data, Internet, and any other services provided over wire, fiber optic, microwave, wireless, and any other transmission systems (“Telecommunications Services”), for part or all of Tenant’s telecommunications within the

-22-

Building and from the Building to any other location without Landlord’s prior written consent. All providers of Telecommunications Services shall be required to comply with the rules and regulations of the Building, applicable Laws and Landlord’s policies and practices for the Building. Tenant acknowledges that Landlord shall not be required to provide or arrange for any Telecommunications Services and that Landlord shall have no liability to any Tenant Party in connection with the installation, operation or maintenance of Telecommunications Services or any equipment or facilities relating thereto. Tenant, at its cost and for its own account, shall be solely responsible for obtaining all Telecommunications Services.

(v) Confidentiality. Tenant acknowledges that the terms and conditions of this Lease are to remain confidential for Landlord’s benefit, and may not be disclosed by Tenant to anyone, by any manner or means, directly or indirectly, without Landlord’s prior written consent; however, Tenant may disclose the terms and conditions of this Lease if required by Law (including any disclosure required by the filing requirements of the Securities and Exchange Commission) or court order, and to its attorneys, accountants, employees and existing or prospective financial partners provided same are advised by Tenant of the confidential nature of such terms and conditions and agree to maintain the confidentiality thereof (in each case, prior to disclosure). Tenant shall be liable for any disclosures made in violation of this Section by Tenant or by any entity or individual to whom the terms of and conditions of this Lease were disclosed or made available by Tenant. The consent by Landlord to any disclosures shall not be deemed to be a waiver on the part of Landlord of any prohibition against any future disclosure.

(w) Authority. Tenant (if a corporation, partnership or other business entity) hereby represents and warrants to Landlord that Tenant is a duly formed and existing entity qualified to do business in the state in which the Premises are located, that Tenant has full right and authority to execute and deliver this Lease, and that each person signing on behalf of Tenant is authorized to do so. Landlord hereby represents and warrants to Tenant that Landlord is a duly formed and existing entity qualified to do business in the state in which the Premises are located, that Landlord has full right and authority to execute and deliver this Lease, and that each person signing on behalf of Landlord is authorized to do so.

(x) Hazardous Materials. The term “Hazardous Materials” means any substance, material, or waste which is now or hereafter classified or considered to be hazardous, toxic, or dangerous under any Law relating to pollution or the protection or regulation of human health, natural resources or the environment, or poses or threatens to pose a hazard to the health or safety of persons on the Premises or in the Project. Tenant shall not use, generate, store, or dispose of, or permit the use, generation, storage or disposal of Hazardous Materials on or about the Premises or the Project except in a manner and quantity necessary for the ordinary performance of Tenant’s business, and then in compliance with all Laws. If Tenant breaches its obligations under this Section 25(x), Landlord may immediately take any and all action reasonably appropriate to remedy the same, including taking all appropriate action to clean up or remediate any contamination resulting from Tenant’s use, generation, storage or disposal of Hazardous Materials. Notwithstanding Landlord’s indemnity contained in Section 11(d), Tenant shall defend, indemnify, and hold harmless Landlord and its representatives and agents from and against any and all claims, demands, liabilities, causes of action, suits, judgments, damages and expenses (including reasonable attorneys’ fees and cost of clean up and remediation) arising from Tenant’s failure to comply with the provisions of this Section 25(x).

(z) Prohibited Persons and Transactions. Tenant represents and warrants that neither Tenant nor any of its affiliates, nor any of their respective partners, members, shareholders or other equity owners, and, to Tenant’s actual knowledge, none of their respective employees, officers or directors is a person or entity with whom U.S. persons or entities are restricted from doing business under regulations of the Office of Foreign Asset Control (“OFAC”) of the Department of the Treasury (including those named on OFAC’s Specially Designated and Blocked Persons List) or under any statute, executive order (including the September 24, 2001, Executive Order Blocking Property and Prohibiting Transactions with Persons Who Commit, Threaten to Commit, or Support Terrorism), or other governmental action and is not and will not Transfer this Lease to, contract with or otherwise engage in any dealings or transactions or be otherwise associated with such persons or entities. Notwithstanding the foregoing, Tenant makes no representation or warranty with respect to any of Tenant’s or Tenant’s affiliates’ shareholders if Tenant or Tenant’s affiliate is a publicly traded corporation.

(aa) Parking. Tenant shall be entitled to 170 undesignated parking spaces, at no charge by Landlord during the initial Term, in the parking area associated with the Building (the “Parking Area”) during the Term subject to such terms, conditions and regulations as are from time to time applicable to patrons of the Parking Area. Tenant shall be responsible for payment of any governmental charges and/or taxes in connection with such parking spaces.

Tenant shall at all times comply with all Laws respecting the use of the Parking Area. Landlord reserves the right to adopt, modify, and enforce reasonable rules and regulations governing the use of the Parking Area from time to time. Landlord may refuse to permit any person who violates such rules and regulations to park in the Parking Area, and any violation of the rules and regulations shall subject the car to removal from the Parking Area.

The parking spaces provided hereunder shall be provided on an unreserved, “first-come, first served” basis. Landlord shall not be responsible for enforcing Tenant’s parking rights against any third parties.

All motor vehicles (including all contents thereof) shall be parked in the Parking Area at the sole risk of Tenant and each other Tenant Party, it being expressly agreed and understood Landlord has no duty to insure any of said motor vehicles (including the contents thereof), and Landlord is not responsible for the protection and security of such vehicles. Notwithstanding anything to the contrary contained in this Lease, Landlord shall have no liability whatsoever for any property damage or loss which might occur on the Parking Area or as a result of or in connection with the parking of motor vehicles in any of the parking spaces.

26. Renewal Option. Provided no Event of Default exists and Tenant is occupying at least 75% of the Premises at the time of such election, Tenant may renew this Lease for two additional periods of five years each, by delivering written notice of the exercise thereof to Landlord not earlier than 12 months nor later than 9 months before the expiration of the Term. The Basic Rent payable for each month during the applicable extended Term shall be the prevailing rental rate (the “Prevailing Rental Rate”), at the commencement of such extended Term, for renewals of space in the Complex or in comparable buildings in the vicinity of the Complex of equivalent quality, size, utility and location, with the length of the extended Term and the credit standing of Tenant to be taken into account, provided however, in no event shall the Prevailing Rental Rate be less than the Basic Rent payable during the month immediately preceding the commencement of the applicable extended Term. Within 30 days after receipt of Tenant’s notice to renew, Landlord shall deliver to Tenant written notice of the Prevailing Rental Rate and shall advise Tenant of the required adjustment to Basic Rent, if any, and the other terms and conditions offered. If Tenant disagrees with Landlord’s determination of the Prevailing Rental Rate, then Tenant may, but only within twenty (20) days after receipt of Landlord’s notice, require by written notice to Landlord that the determination of the Prevailing Rental Rate be made by brokers, taking into account the requirements of this Section 26; provided that Tenant’s failure to deliver such notice within such 20-day period shall be deemed to be Tenant’s acceptance of Landlord’s determination of the Prevailing Rental Rate. If Tenant timely delivers such notice, then, within 10 days after such delivery, each party shall select one qualified commercial real estate broker with at least 10 years experience in appraising property and buildings in the city or submarket in which the Premises are located. If Landlord or Tenant fails to select its broker within such 10-day period, then Landlord or Tenant may petition the then presiding judge of the Superior Court of the State of California for Santa ▇▇▇▇▇ County to appoint such broker, subject to the criteria set forth in this Section 26, or if he or she refuses to act, either party may petition any judge having jurisdiction over Landlord and Tenant to appoint such broker. Each broker shall deliver its written determination of the Prevailing

-24-

Rental Rate, taking into account the requirements of this Section 26, to the other broker within 20 days after such broker’s retention. In the event the determinations of the two brokers differ and, after good faith efforts over the succeeding 20 day period, they cannot mutually agree, the brokers shall, within 10 days thereafter, appoint a neutral third broker with the qualifications specified above and deliver their respective determinations to such third broker. If the two brokers fail to select the third broker within such 10-day period, then Landlord or Tenant may petition the then presiding judge of the Superior Court of the State of California for Santa ▇▇▇▇▇ County to appoint such broker subject to the criteria set forth in this Section 26, or if he or she refuses to act, either party may petition any judge having jurisdiction over the Landlord and Tenant to appoint such broker. Within 5 days after its appointment, the third broker shall choose either the determination of Landlord’s broker or Tenant’s broker and such choice of the third broker shall be final and binding on Landlord and Tenant. Each party shall pay the costs of its real estate broker. The parties shall equally share the costs of any third broker. Following the determination of the Prevailing Rental Rate, Landlord and Tenant shall execute an amendment to this Lease extending the Term on the same terms provided in this Lease, except as follows:

(i) Basic Rent shall be adjusted to the Prevailing Rental Rate;

(ii) Tenant shall have no further renewal option except as expressly provided in this Lease; and

(iii) Landlord shall lease to Tenant the Premises in their then-current condition, and Landlord shall not provide to Tenant any allowances (e.g., moving allowance, construction allowance, and the like) or other tenant inducements except as specifically provided in Landlord’s notice.

Tenant’s rights under this Section 26 shall terminate if (i) this Lease or Tenant’s right to possession of the Premises is terminated, (ii) Tenant assigns any of its interest in this Lease or sublets more than 25% of the Premises to other than a Permitted Transferee, (iii) Tenant fails to timely exercise its option under this Section 26, time being of the essence with respect to Tenant’s exercise thereof, or (iv) based on Tenant’s financial statements audited by a national independent certified public accounting firm (which shall be furnished by Tenant within ten (10) days following Landlord’s request), Tenant’s then net worth is less than fifty (50%) of Tenant’s net worth as of the date of this Lease.

27. Right of First Offer. Subject to then-existing renewal or expansion rights or options of other tenants, and provided no Event of Default then exists, Landlord shall, prior to offering the same to any party (other than the then-current tenant or occupant therein), first offer to lease to Tenant the space in the buildings commonly known as ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇ and ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇ (the “Offer Space”) in an “AS-IS” condition; such offer shall be in writing, shall be given no earlier than 4 months prior to the expiration or earlier termination of the current lease for the ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇ Offer Space, and 6 months prior to the expiration or earlier termination of the current lease for the ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇ Offer Space, if any (it being understood that there shall be no such time limitation with respect to space that is not currently leased and that such offer may be given at any time with respect to such space) and specify the lease terms for the Offer Space, including the rent to be paid for the Offer Space, the term of the lease for the Offer Space and the date on which the Offer Space shall be included in the Premises (the “Offer Notice”). The Offer Notice shall be substantially similar to the Offer Notice attached to this Lease as Exhibit G. Tenant shall notify Landlord in writing whether Tenant elects to lease the entire Offer Space on the terms set forth in the Offer Notice within ten (10) days after Landlord delivers to Tenant the Offer Notice. If Tenant timely elects to lease the Offer Space, then Landlord and Tenant shall execute an amendment to this Lease, effective as of the date the Offer Space is to be included in the Premises, on the terms set forth in the Offer Notice and, to the extent not inconsistent with the Offer Notice terms, the terms of this Lease; however, Tenant shall accept the Offer Space in an “AS-IS” condition and Landlord shall not provide to Tenant any allowances (e.g., moving allowance, construction allowance, and the like) or other tenant inducements except as specifically provided in the Offer Notice. Notwithstanding the foregoing, if prior to Landlord’s delivery to Tenant of the Offer Notice, Landlord has received an offer to lease all or part of the Offer Space from a third party (a “Third Party Offer”) and such Third Party Offer includes space in excess of the Offer Space, Tenant must exercise its rights hereunder, if at all, as to all of the space contained in the Third Party Offer.

If Tenant fails or is unable to timely exercise its right hereunder, then such right shall lapse (except as expressly provided in this sentence), time being of the essence with respect to the exercise thereof (it being understood that Tenant’s right hereunder is a one-time right only as to each Offer Space (except as expressly

-25-

provided in this sentence)), and Landlord may lease all or a portion of the Offer Space to third parties on such terms as Landlord may elect, provided however, if Landlord reduces the Basic Rent by more than ten percent (10%), Landlord shall re-offer the Offer Space to Tenant on the revised terms and Tenant shall have five (5) days in which to notify Landlord that Tenant elects to lease the Offer Space on such revised terms. Tenant may not exercise its rights under this Section 27 if an Event of Default exists or Tenant and/or Permitted Transferee is not then occupying the entire Premises. For purposes hereof, if an Offer Notice is delivered for less than all of the Offer Space but such notice provides for an expansion, right of first refusal, or other preferential right to lease some of the remaining portion of the Offer Space, then such remaining portion of the Offer Space shall thereafter be excluded from the provisions of this Section 27. Landlord shall pay a market commission to Tenant’s broker described in Section 25(d) with respect to any space leased by Tenant under this Section 27 provided Tenant then acknowledges such broker as Tenant’s exclusive agent, and Tenant and Landlord shall each indemnify the other against all costs, expenses, attorneys’ fees, and other liability for commissions or other compensation claimed by any broker or agent other than such Tenant’s broker claiming the same by, through, or under the indemnifying party.

Tenant’s rights under this Section 27 shall terminate if (a) this Lease or Tenant’s right to possession of the Premises is terminated, or (b) Tenant assigns any of its interest in this Lease or sublets any portion of the Premises to other than a Permitted Transferee.

-26-

If any of Tenant’s proposed construction work will affect the Building’s Structure or the Building’s Systems, then the working drawings pertaining thereto must be approved by the Building’s engineer of record. Landlord’s approval of such working drawings shall not be unreasonably withheld, provided that (1) they comply with all Laws, (2) the improvements depicted thereon do not adversely affect (in the reasonable discretion of Landlord) the Building’s Structure or the Building’s Systems (including the Building’s restrooms or mechanical rooms), or the exterior appearance of the Building, (3) such working drawings are sufficiently detailed to allow construction of the improvements in a good and workmanlike manner, and (4) the improvements depicted thereon conform to the rules and regulations promulgated from time to time by Landlord for the construction of tenant improvements. As used herein, “Working Drawings” means the final working drawings approved by Landlord, as amended from time to time by any approved changes thereto, and “Work” means all improvements to be constructed in accordance with and as indicated on the Working Drawings, together with any work required by governmental authorities to be made to other areas of the Complex as a result of the improvements indicated by the Working Drawings. Landlord’s approval of the Working Drawings shall not be a representation or warranty of Landlord that such drawings are adequate for any use or

D-1

comply with any Law, but shall merely be the consent of Landlord thereto. Tenant shall, at Landlord’s request, sign the Working Drawings to evidence its review and approval thereof. After the Working Drawings have been approved, Tenant shall cause the Work to be performed in accordance with the Working Drawings.

4. Contractors; Performance of Work. The Work shall be performed only by licensed contractors and subcontractors approved in writing by Landlord, which approval shall not be unreasonably withheld. All contractors and subcontractors shall be required to procure and maintain insurance against such risks, in such amounts, and with such companies as Landlord may reasonably require. Certificates of such insurance, with paid receipts therefor, must be received by Landlord before the Work is commenced. The Work shall be performed in a good and workmanlike manner free of defects, shall conform strictly with the Working Drawings, and shall be performed in such a manner and at such times as not to interfere with or delay Landlord’s other contractors, the operation of the Complex, and the occupancy thereof by other tenants. All contractors and subcontractors shall contact Landlord and schedule time periods during which they may use Building facilities in connection with the Work (e.g., electricity, etc.).

5. Construction Contracts. Tenant shall enter into a construction contract with a general contractor selected by Tenant and approved by Landlord (which approval shall not be unreasonably withheld) in a form acceptable to Tenant’s representative for the Work, which shall comply with the provisions of this Section 5 and provide for, among other things, (1) a one-year warranty for all defective Work; (2) a requirement that Tenant’s Contractor maintain general commercial liability insurance of not less than a combined single limit of $5,000,000, naming Landlord, Landlord’s property management company, Landlord’s asset management company, Landlord’s Mortgagee, Tenant, and each of their respective Affiliates as additional insureds; (3) a requirement that the contractor perform the Work in accordance with the Space Plans and the Working Drawings and in a good and workmanlike manner; and (4) a requirement that the contractor is responsible for daily cleanup work and final clean up (including removal of debris) (collectively, the “Approval Criteria”).

6. Change Orders. Tenant may initiate changes in the Work. Each such change must receive the prior written approval of Landlord, such approval not to be unreasonably withheld or delayed; however, if such requested change would adversely affect (in the reasonable discretion of Landlord) (a) the Building’s Structure or the Building’s Systems (including the Building’s restrooms or mechanical rooms), or (b) the exterior appearance of the Building, Landlord may withhold its consent in its sole and absolute discretion. Tenant shall, upon completion of the Work, furnish Landlord with an accurate architectural “as-built” plan of the Work as constructed, which plan shall be incorporated into this Exhibit D by this reference for all purposes. If Tenant requests any changes to the Work described in the Space Plans or the Working Drawings, then such increased costs and any additional design costs incurred in connection therewith as the result of any such change shall be added to the Total Construction Costs.

7. Definitions. As used herein “Substantial Completion,” “Substantially Completed,” and any derivations thereof mean the Work in the Premises is substantially completed (as reasonably determined by Landlord) in accordance with the Working Drawings and the City of Sunnyvale has issued a certificate of occupancy or similar approval allowing Tenant to legally occupy the Premises. Substantial Completion shall have occurred even though minor “punch list” details of construction, decoration and mechanical adjustments remain to be completed.

8. Walk-Through; Punchlist. When Tenant considers the Work in the Premises to be Substantially Completed, Tenant will notify Landlord and within three business days thereafter, Landlord’s representative and Tenant’s representative shall conduct a walk-through of the Premises and identify any necessary touch-up work, repairs and minor completion items that are necessary for final completion of the Work. Tenant shall cause the contractor performing the Work to diligently prosecute to completion all such punchlist items.

9. Excess Costs. The entire cost of performing the Work (including design of and space planning for the Work and preparation of the Working Drawings and the final “as-built” plan of the Work, costs of construction labor and materials, electrical and other utility usage during construction, janitorial services, general tenant signage, related taxes and insurance costs, licenses, permits, certifications, surveys and other approvals required by Law, and the construction supervision fee referenced in Section 11 of this Exhibit, all of which costs are herein collectively called the “Total Construction Costs”) in excess of the “Construction Allowance” (as hereinafter defined) shall be paid by Tenant. Upon approval of the Working Drawings and selection of a contractor, Tenant shall promptly execute a work order agreement which identifies such drawings and itemizes the Total Construction Costs and sets forth the Construction Allowance.

D-2

10. Construction Allowance. Landlord shall provide to Tenant a construction allowance not to exceed $687,345.00 (the “Construction Allowance”) to be applied toward the Total Construction Costs, as adjusted for any changes to the Work, provided however, if following Substantial Completion of the Work, Total Construction Costs are less than the Construction Allowance, Tenant may use up to $229,115.00 of any remaining balance of the Construction Allowance to reimburse Tenant for Tenant’s costs of furniture, fixtures and equipment and data and communications cabling upon Tenant furnishing Landlord with satisfactory evidence of such costs and Tenant’s payment thereof. In addition to the Construction Allowance, Landlord will also reimburse to Tenant an amount not to exceed $2,291.15 for the costs of a “test fit” of the Premises upon Tenant furnishing Landlord with satisfactory evidence of such costs and Tenant’s payment thereof (the “Test Fit Payment”). No advance of the Construction Allowance shall be made by Landlord until Tenant has first paid to the contractor from its own funds (and provided reasonable evidence thereof to Landlord) the anticipated amount by which the projected Total Construction Costs exceed the amount of the Construction Allowance. Thereafter, Landlord shall pay to Tenant the Construction Allowance in multiple disbursements (but not more than once in any calendar month) following the receipt by Landlord of the following items: (a) a request for payment, (b) final or partial lien waivers, as the case may be, from all persons performing work or supplying or fabricating materials for the Work, fully executed, acknowledged and in recordable form, and (c) the Architect’s certification that the Work for which reimbursement has been requested has been finally completed, including (with respect to the last application for payment only) any punch-list items, on the appropriate AIA form or another form approved by Landlord, and, with respect to the disbursement of the last 20% of the Construction Allowance: (1) the permanent certificate of occupancy issued for the Premises, (2) Tenant’s occupancy of the Premises, and (3) delivery of the architectural “as-built” plan for the Work as constructed (and as set forth above) to Landlord’s construction representative (set forth below) (collectively, a “Completed Application for Payment”). Landlord shall pay the amount requested in the applicable Completed Application for Payment to Tenant within 30 days following Tenant’s submission of the Completed Application for Payment. If, however, the Completed Application for Payment is incomplete or incorrect, Landlord’s payment of such request shall be deferred until 30 days following Landlord’s receipt of the Completed Application for Payment. Notwithstanding anything to the contrary contained in this Exhibit, Landlord shall not be obligated to make any disbursement of the Construction Allowance during the pendency of any of the following: (A) Landlord has received written notice of any unpaid claims relating to any portion of the Work or materials in connection therewith, other than claims which will be paid in full from such disbursement, (B) there is an unbonded lien outstanding against the Complex, the Premises or Tenant’s interest therein by reason of work done, or claimed to have been done, or materials supplied or specifically fabricated, or claimed to have been supplied or specifically fabricated, to or for Tenant or the Premises, (C) the conditions to the advance of the Construction Allowance are not satisfied, or (D) an Event of Default by Tenant exists. The Construction Allowance must be used (that is, the Work must be fully complete and the Construction Allowance disbursed) and the Test Fit Payment disbursed within six months following the Commencement Date or shall be deemed forfeited with no further obligation by Landlord with respect thereto.

11. Construction Management. Landlord or its Affiliate or agent shall supervise the Work and coordinate the relationship between the Work, the Building and the Building’s Systems. In consideration for Landlord’s construction supervision services, Tenant shall pay to Landlord a construction supervision fee equal to $15,000.

12. Construction Representatives. Landlord’s and Tenant’s representatives for coordination of construction and approval of change orders will be as follows, provided that either party may change its representative upon written notice to the other:
