ARTICLE 1

Premises, Building, Project, and Common Areas

1.1 Premises, Building, Project and Common Areas.

1.1.1 The Premises. Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the premises set forth in Section 2.2 of the Summary (the “Premises”). The outline of the Premises is set forth in Exhibit A attached hereto and the Premises contain approximately the number of rentable square feet as set forth in Section 2.2 of the Summary. The parties hereto agree that the lease of the Premises is upon and subject to the terms, covenants and conditions herein set forth, and Tenant covenants as a material part of the consideration for this Lease to keep and perform each and all of such terms, covenants and conditions by it to be kept and performed and that this Lease is made upon the condition of such performance. The parties hereto hereby acknowledge that the purpose of Exhibit A is to show the approximate location of the Premises in the “Building,” as that term is defined in Section 1.1.2 below, only, and such Exhibit is not meant to constitute an agreement, representation or warranty as to the construction of the Premises, the precise area thereof or the specific location of the “Common Areas,” as that term is defined in Section 1.1.3 below, or the elements thereof or of the accessways to the Premises or the “Project,” as that term is defined in Section 1.1.2 below. Except as specifically set forth in this Lease and in the Tenant Work Letter attached hereto as Exhibit B (the “Tenant Work Letter”), Landlord shall not be obligated to provide or pay for any improvement work or services related to the improvement of the Premises. Tenant also acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty regarding the condition of the Premises, the Building or the Project or with respect to the suitability of any of the foregoing for the conduct of Tenant’s business, except as specifically set forth in this Lease and the Tenant Work Letter. The taking of possession of the Premises by Tenant shall conclusively establish that the Premises and the Building were at such time in good and sanitary condition and repair (with the exception of latent defects).

1.1.2 The Building and the Project. The Premises are a part of the building set forth in Section 2.1 of the Summary (the “Building”). The Building is part of an office project known as ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇. The term “Project,” as used in this Lease, shall mean (i) the Building and the Common Areas, and (ii) the land (which is improved with landscaping, parking facilities and other improvements) upon which the Building and the Common Areas are located.

1.1.3 Common Areas. Tenant shall have the non-exclusive right to use in common with other tenants in the Project, and subject to the rules and regulations referred to in Article 5 of this Lease, those portions of the Project which are provided, from time to time, for use in common by Landlord, Tenant and any other tenants of the Project (such areas are collectively referred to herein as the “Common Areas”). The Common Areas shall be maintained and operated by Landlord in a manner consistent with other comparable office buildings in the vicinity of the Building, and the use thereof shall be subject to such reasonable rules, regulations and restrictions as Landlord may make from time to time, provided that Tenant shall not be bound by any such rules and regulations of which it has not been given reasonable prior notice and provided further that all such rules and regulations shall be enforced in a non-discriminatory manner. Landlord reserves the right to close temporarily, make alterations or additions to, or change the location of elements of the Project and the Common Areas; provided, however, that no such closure, alteration, addition or change, unless required as a result of an emergency or by Applicable Law, shall materially and adversely affect Tenant’s rights hereunder.

1.2 Rentable Square Feet of Premises and Building. For purposes of this Lease, “rentable square feet” in the Premises, the Building and the Project, as the case may be, shall be calculated in accordance with the Standard Method for ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇ ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇.▇-▇▇▇▇, promulgated by the Building Owners And Managers Association (BOMA) (“Measurement Standard”). Notwithstanding anything to the contrary set forth in Section 2.2 of the Summary or elsewhere in this Lease, the rentable area of the Premises and any ROFO Spaces (as defined in Addendum 1) is subject to verification by Landlord’s space planner pursuant to the Measurement Standard from time to time (the “Measurement Verification”). In the event that Landlord’s space planner determines that the

rentable area of the Premises shall be different from that set forth in Section 2.2 of the Summary, then all amounts, percentages and figures appearing or referred to in this Lease based upon such incorrect rentable area (including, without limitation, the amounts of “Base Rent,” the “Tenant Improvement Allowance,” and “Tenant’s Share,” as those terms are defined in this Lease, respectively) shall be modified in accordance with such determination. Notwithstanding the foregoing, if Tenant notifies Landlord that Tenant objects to the Measurement Verification within thirty (30) days after Tenant’s receipt of the Measurement Verification from Landlord, then, at Tenant’s sole cost and expense, the Premises shall be measured by an independent architect jointly selected by Landlord and Tenant and, if applicable, all amounts, percentages and figures appearing or referred to in this Lease based upon such incorrect rentable area (including, without limitation, the amounts of “Base Rent,” the “Tenant Improvement Allowance,” and “Tenant’s Share”) shall be modified in accordance with such determination. Notwithstanding the foregoing, Landlord may remeasure the Building and/or the Project, from time to time, in accordance with the Measurement Standard, and if the rentable area of the Premises, the Building and/or the Project shall change as measured in such remeasurement, then the rentable area of the Premises and/or the Building, as the case may be, shall be appropriately adjusted as of the date of such remeasurement based upon the written verification by Landlord’s space planner of such revised rentable area. Any such remeasurement by Landlord shall be subject to verification by Tenant in accordance with this Section 1.2.

ARTICLE 2

LEASE TERM

2.1 Lease Term. The terms and provisions of this Lease shall be effective as of the date of this Lease. The term of this Lease (the “Lease Term”) shall be for approximately the number of months set forth in Section 3.1 of the Summary, shall commence on the date (the “Lease Commencement Date”) which is the earlier to occur of (i) April 1, 2011, or (ii) the date Tenant commences business operations in the Premises, and shall terminate on the date (the “Lease Expiration Date”) which is the last day of the sixty-third (63^rd) full calendar month following the Lease Commencement Date, unless this Lease is sooner terminated as hereinafter provided. For purposes of this Lease, the term “Lease Year” shall mean each consecutive twelve (12) month period during the Lease Term; provided, however, that the last Lease Year shall end on the Lease Expiration Date. At any time during the Lease Term, Landlord may deliver to Tenant a notice, in substantially the form set forth in Exhibit C attached hereto, as a confirmation only of the information set forth therein, which Tenant shall execute and return to Landlord within fifteen (15) business days of receipt thereof; provided, however, that Tenant’s failure to execute and return such notice to Landlord within such time shall be conclusive proof upon Tenant that the information set forth in such notice is as specified therein. Landlord shall permit Tenant to access and enter the Premises upon the mutual execution of this Lease (the “Early Entry Date”), solely for purposes of installing the Tenant Improvements. In no event may Tenant conduct its business or operations from the Premises until the Lease Commencement Date. Such limited purpose entry and use of the Premises by Tenant shall be at Tenant’s sole risk and shall also be subject to all of the provisions of this Lease including, but not limited to, the requirement to obtain the insurance required pursuant to this Lease and to deliver insurance certificates as required herein, and to pay for all utilities consumed in the Premises on and after the Early Entry Date. Notwithstanding the immediately preceding sentence, Tenant shall not be required to pay Rent (other than any utilities costs incurred) prior to the Lease Commencement Date. In addition to the foregoing, Landlord shall have the right to impose such additional conditions on Tenant’s early entry as Landlord shall deem reasonably appropriate. If, at any time, there is an Event of Default that results in termination of the Lease, then any such waiver by Landlord of Tenant’s requirement to pay rental payments shall be null and void, and as a component of Landlord’s recovery set forth in Article 19 of the Lease, Tenant shall immediately pay to Landlord all rental payments so waived by Landlord.

2.2 Option to Extend.

2.2.1 Grant of Extension Option. Subject to the provisions, limitations and conditions set forth in this Section 2.2, Tenant shall have one (1) option (“Option”) to extend the Lease Term for five (5) years (the “Extended Term”).

2.2.2 Tenant’s Option Notice. Tenant shall have the right to deliver written notice to Landlord of its intent to exercise the Option (the “Option Notice”). If Landlord does not receive an Option Notice from Tenant on a date which is neither more than twelve (12) months nor less than nine (9) months prior to the initial Lease Expiration

Date, all rights under this Option shall automatically terminate and shall be of no further force or effect. Upon the proper exercise of the Option, subject to the provisions, limitations and conditions set forth in Paragraph 2.2.5 below, the initial Lease Term shall be extended for the Extended Term.

2.2.3 Establishing the Initial Monthly Base Rent for the Extended Term. The initial monthly Base Rent for the Extended Term shall be equal to the then Fair Market Rental Rate, as hereinafter defined. As used herein, the “Fair Market Rental Rate” payable by Tenant for the Extended Term shall mean the Base Rent for the highest and best use for comparable space at which non-equity tenants, as of the commencement of the lease term for the Extended Term, will be leasing non-sublease, non-equity, unencumbered space comparable in size, location and quality to the Premises for a comparable term, which comparable space is located in the Building and in other comparable first-class buildings in the vicinity of the Building including other first-class office buildings in the San Francisco Central Business District office market, taking into consideration all free rent and other out-of-pocket concessions generally being granted at such time for such comparable space, including the condition and value of existing tenant improvements in the Premises. The Fair Market Rental Rate shall include the periodic rental increases that would be included for space leased for the period of the Extended Term.

If Landlord and Tenant are unable to agree on the Fair Market Rental Rate for the Extended Term within ten (10) days of receipt by Landlord of the Option Notice for the Extended Term, Landlord and Tenant each, at its cost and by giving notice to the other party, shall appoint a competent and impartial commercial real estate broker (hereinafter “broker”) with at least ten (10) years’ full-time commercial real estate brokerage experience in the geographical area of the Premises to set the Fair Market Rental Rate for the Extended Term. If either Landlord or Tenant does not appoint a broker within ten (10) days after the other party has given notice of the name of its broker, the single broker appointed shall be the sole broker and shall set the Fair Market Rental Rate for the Extended Term. If two (2) brokers are appointed by Landlord and Tenant as stated in this paragraph, they shall meet promptly and attempt to set the Fair Market Rental Rate. In addition, if either of the first two (2) brokers fails to submit their opinion of the Fair Market Rental Rate within the time frames set forth below, then the single Fair Market Rental Rate submitted shall automatically be the initial monthly Base Rent for the Extended Term and shall be binding upon Landlord and Tenant. If the two (2) brokers are unable to agree within ten (10) days after the second broker has been appointed, they shall attempt to select a third broker, meeting the qualifications stated in this paragraph within ten (10) days after the last day the two (2) brokers are given to set the Fair Market Rental Rate. If the two (2) brokers are unable to agree on the third broker, either Landlord or Tenant by giving ten (10) days’ written notice to the other party, can apply to the Presiding Judge of the Superior Court of the county in which the Premises is located for the selection of a third broker who meets the qualifications stated in this paragraph. Landlord and Tenant each shall bear one-half (¹⁄₂) of the cost of appointing the third broker and of paying the third broker’s fee. The third broker, however selected, shall be a person who has not previously acted in any capacity for either Landlord or Tenant. Within fifteen (15) days after the selection of the third broker, the third broker shall select one of the two Fair Market Rental Rates submitted by the first two brokers as the Fair Market Rental Rate for the Extended Term. The determination of the Fair Market Rental Rate by the third broker shall be binding upon Landlord and Tenant.

Upon determination of the initial monthly Base Rent for the Extended Term in accordance with the terms outlined above, Landlord and Tenant shall immediately execute an amendment to this Lease. Such amendment shall set forth the initial monthly Base Rent for the Extended Term and the actual commencement date and expiration date of the Extended Term and such other terms and conditions as may be mutually agreed-upon by Landlord and Tenant. Tenant shall have no other right to extend the Lease Term under this Section 2.2 unless Landlord and Tenant otherwise agree in writing.

2.2.4 Condition of Premises. If Tenant timely and properly exercises the Option, in strict accordance with the terms contained herein, Tenant shall accept the Premises in its then “As-Is” condition and, accordingly, Landlord shall not be required to perform any additional improvements to the Premises.

2.2.5 Limitations On, and Conditions To, Extension Option. The Option provided for herein is personal to Tenant and may not be assigned, voluntarily or involuntarily, separate from or as part of the Lease (except in connection with a Permitted Transfer). At Landlord’s option, all rights of Tenant under this Section 2.2 shall terminate and be of no force or effect if any of the following individual events occur or any combination thereof occur: (i) an Event of Default has occurred at any time during the eighteen (18) month period prior to the date Tenant delivers an

Option Notice, or an Event of Default exists at the time Landlord receives an Option Notice; and/or (ii) Tenant has assigned its rights and obligations under all or part of the Lease or Tenant has subleased all or part of the Premises (except in connection with a Permitted Transfer and except for any sublease of any ROFO Space); and/or (iii) Tenant’s financial condition on the date of delivery of the Option Notice is, in the reasonable judgment of Landlord, not adequate to support Tenant’s obligations under this Lease; and/or (iv) Tenant has failed to exercise properly an Option in a timely manner in strict accordance with the provisions of this Section 2.2; and/or (v) Tenant no longer has possession of all or any part of the Premises under this Lease (except in connection with a Permitted Transfer and except in connection with any permitted sublease of the ROFO Space), or if this Lease has been terminated earlier, pursuant to the terms and provisions of this Lease.

ARTICLE 3

BASE RENT

3.1 Base Rent. From and after the Lease Commencement Date, Tenant shall pay, without prior notice or demand, to Landlord or Landlord’s agent at the address set forth in Section 11.2 of the Summary, or, at Landlord’s option, at such other place as Landlord may from time to time designate in writing, by a check for currency which, at the time of payment, is legal tender for private or public debts in the United States of America, base rent (“Base Rent”) as set forth in Section 4 of the Summary, payable in equal monthly installments in advance on or before the first day of each and every calendar month during the Lease Term, without any setoff or deduction whatsoever. The Base Rent for the first full month of the Lease Term shall be paid at the time of Tenant’s execution of this Lease. If any Rent payment date (including the Lease Commencement Date) falls on a day of the month other than the first day of such month or if any payment of Rent is for a period which is shorter than one month, the Rent for any fractional month shall accrue on a daily basis for the period from the date such payment is due to the end of such calendar month or to the end of the Lease Term at a rate per day which is equal to 1/365 of the applicable annual Rent. All other payments or adjustments required to be made under the terms of this Lease that require proration on a time basis shall be prorated on the same basis.

3.2 Rent Abatement. Notwithstanding anything to the contrary contained herein and provided that Tenant faithfully performs all of the terms and conditions of this Lease, and no Event of Default by Tenant occurs hereunder, Landlord hereby agrees that Tenant shall not be required to pay monthly installments of Base Rent for the first (1^st) through third (3^rd) full months of the initial Lease Term (the “Abatement Period”), with the abated Base Rent to be equal to One Hundred Thirty-Six Thousand One Hundred Forty-Nine and 99/100 Dollars ($136,149.99) in the aggregate (the “Abated Base Rent”). During the Abatement Period, Tenant shall still be responsible for the payment of all of its other monetary obligations under this Lease. In the Event of a Default under the terms of this Lease in accordance with the provisions of Article 19 hereof that results in a termination of the Lease, then as a part of the recovery set forth in Article 19 of this Lease, Landlord shall be entitled to the recovery of all Abated Base Rent that was abated under the provisions of this Article 3.

ARTICLE 4

ADDITIONAL RENT

4.1 General Terms. In addition to paying the Base Rent specified in Article 3 of this Lease, Tenant shall pay with respect to the Lease Term “Tenant’s Share” of the annual “Direct Expenses,” as those terms are defined in Sections 4.2.6 and 4.2.2 of this Lease, respectively, which are in excess of the amount of Direct Expenses applicable to the “Base Year,” as that term is defined in Section 4.2.1 below; provided, however, that in no event shall any decrease in Direct Expenses for any Expense Year below Direct Expenses for the Base Year entitle Tenant to any decrease in Base Rent or any credit against sums due under this Lease. Such payments by Tenant, together with any and all other amounts payable by Tenant to Landlord pursuant to the terms of this Lease, are hereinafter collectively referred to as the “Additional Rent”, and the Base Rent and the Additional Rent and all other sums payable by Tenant to Landlord hereunder are herein collectively referred to as “Rent.” All amounts due under this Article 4 as Additional Rent shall be payable for the same periods and in the same manner as the Base Rent. Without limitation on other obligations of Tenant which survive the expiration of the Lease Term, the obligations of Tenant to pay the Additional Rent provided for in this Article 4 shall survive the expiration of the Lease Term.

4.2 Definitions of Key Terms Relating to Additional Rent. As used in this Article 4, the following terms shall have the meanings hereinafter set forth:

4.2.1 “Base Year” shall mean calendar year 2011.

4.2.2 “Direct Expenses” shall mean “Operating Expenses” and “Tax Expenses.”

4.2.3 “Expense Year” shall mean each calendar year in which any portion of the Lease Term falls, through and including the calendar year in which the Lease Term expires, provided that Landlord, upon notice to Tenant, may change the Expense Year from time to time to any other twelve (12) consecutive month period, and, in the event of any such change, Tenant’s Share of Direct Expenses shall be equitably adjusted for any Expense Year involved in any such change.

4.2.4 “Operating Expenses” shall mean all expenses, costs and amounts of every kind and nature which Landlord pays or accrues during any Expense Year because of or in connection with the ownership, management, maintenance, security, repair, replacement, restoration or operation of the Project, or any portion thereof. Without limiting the generality of the foregoing, Operating Expenses shall specifically include any and all of the following: (i) the cost of supplying all utilities (to the extent the same is not being paid directly by Tenant), the cost of operating, repairing, maintaining, replacing, renovating and managing the utility, telephone, communications, mechanical, sanitary, storm drainage, and elevator systems, and the cost of supplies, tools, equipment and maintenance and service contracts in connection therewith; (ii) the cost of licenses, certificates, permits and inspections and the cost of reasonably contesting any governmental enactments which may affect Operating Expenses, and the costs incurred in connection with a transportation system management program or similar program; (iii) the cost of all insurance carried by Landlord in connection with the Project; (iv) the cost of landscaping, relamping, and all supplies, tools, equipment and materials used in the operation, repair and maintenance of the Project, or any portion thereof; (v) the costs incurred in connection with the parking areas servicing the Project; (vi) fees and other costs, including management fees, consulting fees, legal fees and accounting fees, of all contractors and consultants in connection with the management, operation, maintenance and repair of the Project; (vii) payments under any equipment rental agreements and the fair rental value of any management office space; (viii) wages, salaries and other compensation and benefits, including taxes levied thereon, of all persons engaged in the operation, maintenance and security of the Project on a full time basis and an appropriate portion of same with respect to persons engaged on a part-time basis; (ix) costs under any instrument pertaining to the sharing of costs by the Project; (x) operation, repair, maintenance and replacement of all systems and equipment and components thereof of the Building; (xi) the cost of janitorial, alarm, security and other services; (xii) the costs of repair, replacement and restoration of the Common Areas, including the costs of replacement of wall and floor coverings, ceiling tiles and fixtures, curbs and walkways; (xiii) the costs of repair to roofs and re-roofing; (xiv) amortization (including interest on the unamortized cost) of the cost of acquiring or the rental expense of personal property used in the maintenance, operation and repair of the Project, or any portion thereof; (xv) the cost of capital improvements or other costs incurred in connection with the Project (A) which are intended as a labor-saving device or to effect economies in the operation or maintenance of the Project, or any portion thereof, or (B) that are made to the Project after the date of this Lease and that are required under any governmental law or regulation first enacted, interpreted or applicable to the Project after the Lease Commencement Date; provided, however, that any capital expenditure shall be amortized on a straight-line basis with interest at the “prime rate” or “reference rate” announced from time to time by Bank of America, N.T. & S.A., (or such reasonable comparable national banking institution as is selected by Landlord in the event Bank of America, N.T. & S.A., ceases to publish a prime rate or reference rate), plus two percent (2%), over its useful life as reasonably determined by Landlord using accounting principles consistently applied; (xvi) costs, fees, charges or assessments imposed by, or resulting from any mandate imposed on Landlord by, any federal, state or local government for fire and police protection, trash removal, community services, or other services which do not constitute “Tax Expenses” as that term is defined in Section 4.2.5 below; and (xvii) payments under any easement, license, operating agreement, declaration, restrictive covenant, or instrument pertaining to the sharing of costs by the Building.

If Landlord is not furnishing any particular work or service (the cost of which, if performed by Landlord, would be included in Operating Expenses) to a tenant who has undertaken to perform such work or service in lieu of the performance thereof by Landlord, Operating Expenses shall be deemed to be increased by an amount equal to the additional Operating Expenses which would reasonably have been incurred during such period by Landlord if it had at its

own expense furnished such work or service to such tenant. If the Project is not at least one hundred percent (100%) occupied during all or a portion of the Base Year or any Expense Year, Landlord shall make an appropriate adjustment to the variable cost components of Operating Expenses for such year to determine the amount of Operating Expenses that would have been incurred had the Project been one hundred percent (100%) occupied; and the amount so determined shall be deemed to have been the amount of Operating Expenses for such year. Operating Expenses for the Base Year shall not include temporary market-wide labor-rate increases due to extraordinary circumstances, including, but not limited to, boycotts and strikes, and temporary utility rate increases due to extraordinary circumstances including, but not limited to, conservation surcharges, boycotts, embargoes or other shortages. Operating Expenses for the Base Year shall include amortized costs relating to capital improvements, provided that at such time as any such costs are no longer included in Operating Expenses, such costs shall be excluded from the Base Year calculation of Operating Expenses. Notwithstanding the foregoing, Operating Expenses shall not, however, include: (A) costs of leasing commissions, attorneys’ fees and other costs and expenses (including advertising and promotional costs) incurred in connection with negotiations or disputes with present or prospective tenants or other occupants of the Building; (B) costs (including permit, license and inspection costs) incurred in renovating or otherwise improving, decorating or redecorating rentable space for other tenants or vacant rentable space; (C) costs of overhead or profit increment paid to Landlord or to subsidiaries or affiliates of Landlord for services in or in connection with the Building to the extent the same exceeds the costs of overhead and profit increment included in the costs of such services which could be obtained from third parties on a competitive basis; (D) except as otherwise specifically provided in this Section 4.2.4, costs of principal and interest on debt or amortization on any mortgages, and rent payable under any ground lease of the Project; (E) reserves for expenses beyond those for current year anticipated expenses; (F) except as otherwise provided in this Lease, the cost of any capital improvements; (G) costs associated with the investigation and/or remediation of Hazardous Materials (hereafter defined) present in, on or about the Project, unless such costs and expenses are the responsibility of Tenant as provided in Article 5 of this Lease, in which event all such costs and expenses shall be paid solely by Tenant in accordance with the provisions of Article 5; (H) Landlord’s general corporate overhead and administrative expenses except for the property management fee and except as they relate to the specific management of the Project; (I) costs to the extent Landlord is reimbursed directly by other tenants of the Building or through insurance proceeds; and (J) costs of correcting defects in, or significant design error relating to, the initial design or construction of the Building.

4.2.5 Taxes.

4.2.5.1 “Tax Expenses” shall mean all federal, state, county, or local governmental or municipal taxes, fees, charges or other impositions of every kind and nature, whether general, special, ordinary or extraordinary (including, without limitation, real estate taxes, general and special assessments, transit taxes, leasehold taxes or taxes based upon the receipt of rent, including gross receipts or sales taxes applicable to the receipt of rent, unless required to be paid by Tenant, personal property taxes imposed upon the fixtures, machinery, equipment, apparatus, systems and equipment, appurtenances, furniture and other personal property used in connection with the Project, or any portion thereof), which shall be paid or accrued during any Expense Year (without regard to any different fiscal year used by such governmental or municipal authority) because of or in connection with the ownership, leasing and operation of the Project, or any portion thereof.

4.2.5.2 Tax Expenses shall include, without limitation: (i) Any tax on the rent, right to rent or other income from the Project, or any portion thereof, or as against the business of leasing the Project, or any portion thereof; (ii) Any assessment, tax, fee, levy or charge in addition to, or in substitution, partially or totally, of any assessment, tax, fee, levy or charge previously included within the definition of real property tax, it being acknowledged by Tenant and Landlord that Proposition 13 was adopted by the voters of the State of California in the June 1978 election (“Proposition 13”) and that assessments, taxes, fees, levies and charges may be imposed by governmental agencies for such services as fire protection, street, sidewalk and road maintenance, refuse removal and for other governmental services formerly provided without charge to property owners or occupants, and, in further recognition of the decrease in the level and quality of governmental services and amenities as a result of Proposition 13, Tax Expenses shall also include any governmental or private assessments or the Project’s contribution towards a governmental or private cost-sharing agreement for the purpose of augmenting or improving the quality of services and amenities normally provided by governmental agencies; (iii) Any assessment, tax, fee, levy, or charge allocable to or measured by the area of the Premises or the Rent payable hereunder, including, without limitation, any business or gross receipts or excise tax with respect to the receipt of such rent, or upon or with respect to the possession, leasing, operating, management,

maintenance, alteration, repair, use or occupancy by Tenant of the Premises, or any portion thereof; (iv) Any assessment, tax, fee, levy or charge, upon this transaction or any document to which Tenant is a party, creating or transferring an interest or an estate in the Premises; and (v) All of the real estate taxes and assessments imposed upon or with respect to the Building and/or the Project. If the Building or the Project is not fully assessed in the Base Year and any Expense Years, then the Landlord shall adjust the subject year’s Tax Expenses to reflect what such year’s Tax Expenses would have been had the Building/Project been fully completed and assessed for tax purposes.

4.2.5.3 Any reasonable costs and expenses (including, without limitation, reasonable attorneys’ fees) incurred in attempting to protest, reduce or minimize Tax Expenses shall be included in Tax Expenses in the Expense Year such expenses are paid. Except as set forth in Section 4.2.5.4 below, refunds of Tax Expenses shall be credited against Tax Expenses and refunded to Tenant regardless of when received, based on the Expense Year to which the refund is applicable, provided that in no event shall the amount to be refunded to Tenant for any such Expense Year exceed the total amount paid by Tenant as Additional Rent under this Article 4 for such Expense Year. If Tax Expenses for any period during the Lease Term or any extension thereof are increased after payment thereof for any reason, including, without limitation, error or reassessment by applicable governmental or municipal authorities, Tenant shall pay Landlord, within thirty (30) days following submission to Tenant of an invoice from Landlord, together with reasonable back-up documentation, Tenant’s Share of any such increased Tax Expenses included by Landlord as Building Tax Expenses pursuant to the terms of this Lease. Notwithstanding anything to the contrary contained in this Section 4.2.5 (except as set forth in Section 4.2.5.1 above), there shall be excluded from Tax Expenses (i) all excess profits taxes, franchise taxes, gift taxes, capital stock taxes, inheritance and succession taxes, estate taxes, federal and state income taxes, and other taxes to the extent applicable to Landlord’s general or net income (as opposed to rents, receipts or income attributable to operations at the Project), (ii) any items included as Operating Expenses, and (iii) any items paid by Tenant under Section 4.5 of this Lease or which would be payable by any other tenant of the Project pursuant to the terms of Section 4.5, irrespective of whether or not such other tenants’ leases contain provisions comparable to Section 4.5 hereof. In no event shall Tax Expenses include any interest or penalties incurred solely as a result of Landlord’s late payment of Tax Expenses.

4.2.5.4 Notwithstanding anything to the contrary set forth in this Lease, the amount of Tax Expenses for the Base Year and any Expense Year shall be calculated without taking into account any decreases in real estate taxes obtained in connection with Proposition 8, and, therefore, the Tax Expenses in the Base Year and/or an Expense Year may be greater than those actually incurred by Landlord, but shall, nonetheless, be the Tax Expenses due under this Lease; provided that (i) any costs and expenses incurred by Landlord in securing any Proposition 8 reduction shall not be deducted from Tax Expenses nor included in Direct Expenses for purposes of this Lease, and (ii) tax refunds under Proposition 8 shall not be deducted from Tax Expenses nor refunded to Tenant, but rather shall be the sole property of Landlord. Landlord and Tenant acknowledge that this Section 4.2.5.4 is not intended to in any way affect (A) the inclusion in Tax Expenses of the statutory two percent (2.0%) annual increase in Tax Expenses (as such statutory increase may be modified by subsequent legislation), or (B) the inclusion or exclusion of Tax Expenses pursuant to the terms of Proposition 13, which shall be governed pursuant to the terms of Sections 4.2.5.1 through 4.2.5.3 above.

4.2.6 “Tenant’s Share” shall mean the percentage ratio that the number of rentable square feet in the Premises bears to the number of rentable square feet in the Building. If Tenant’s Share shall be adjusted in accordance with Section 1.2 above at any time after the Base Year, then, as to the Expense Year in which such change occurs, Tenant’s Share for such Expense Year shall be determined on the basis of the number of days during such Expense Year that each such Tenant’s Share was in effect.

4.3 Allocation of Direct Expenses. Landlord shall have the right, from time to time, to equitably allocate some or all of the Direct Expenses for the Project among different portions or occupants of the Project (the “Cost Pools”), in Landlord’s reasonable discretion. Such Cost Pools may include, but shall not be limited to, the office space tenants of the Project, and the retail space tenants of the Project. The Direct Expenses within each such Cost Pool shall be allocated and charged to the tenants within such Cost Pool in an equitable manner.

4.4 Calculation and Payment of Additional Rent. If for any Expense Year ending or commencing within the Lease Term, Tenant’s Share of Direct Expenses for such Expense Year exceeds Tenant’s Share of Direct Expenses applicable to the Base Year, then Tenant shall pay to Landlord, in the manner set forth in Section 4.4.1 below, and as Additional Rent, an amount equal to the excess (the “Excess”).

4.4.1 Statement of Actual Direct Expenses and Payment by Tenant. Landlord shall promptly deliver to Tenant, and, in any event shall do so within two hundred seventy (270) days following the end of each Expense Year, a statement (the “Statement”) which shall state the Direct Expenses incurred or accrued for such preceding Expense Year, and which shall indicate the amount of the Excess. Upon receipt of the Statement for each Expense Year commencing or ending during the Lease Term, if an Excess is present, Tenant shall pay, within thirty (30) days, the full amount of the Excess for such Expense Year, less the amounts, if any, paid during such Expense Year as “Estimated Excess,” as that term is defined in Section 4.4.2 below. If the amounts paid by Tenant during an Expense Year as Estimated Excess exceed the Excess for such Expense Year, then such difference shall be refunded to Tenant, provided that any refund may, at Landlord’s option, be credited against Additional Rent next coming due under this Lease. The failure of Landlord to timely furnish the Statement for any Expense Year shall not prejudice Landlord or Tenant from enforcing its rights under this Article 4. Even though the Lease Term has expired and Tenant has vacated the Premises, when the final determination is made of Tenant’s Share of Direct Expenses for the Expense Year in which this Lease terminates, if an Excess if present, Tenant shall pay to Landlord such amount within thirty (30) days of its receipt of the Statement with respect thereto. The provisions of this Section 4.4.1 shall survive the expiration or earlier termination of the Lease Term.

4.4.2 Statement of Estimated Direct Expenses. In addition, Landlord shall endeavor to give Tenant a yearly expense estimate statement (the “Estimate Statement”) which shall set forth Landlord’s reasonable estimate (the “Estimate”) of what the total amount of Direct Expenses for the then-current Expense Year shall be and the estimated excess (the “Estimated Excess”) as calculated by comparing the Direct Expenses for such Expense Year, which shall be based upon the Estimate, to the amount of Direct Expenses for the Base Year. The failure of Landlord to timely furnish the Estimate Statement for any Expense Year shall not preclude Landlord from enforcing its rights to collect any Estimated Excess under this Article 4, nor shall Landlord be prohibited from revising any Estimate Statement or Estimated Excess theretofore delivered at any time during such Expense Year to take into account variations in the Estimate made by Landlord. If pursuant to the Estimate Statement an Estimated Excess is calculated for the then-current Expense Year, Tenant shall pay, with its next installment of Base Rent due, a fraction of the Estimated Excess (such amount referred to herein as the “True-Up Amount”) for the then-current Expense Year (reduced by any amounts paid pursuant to the last sentence of this Section 4.4.2). Such fraction shall have as its numerator the number of months which have elapsed in such current Expense Year, including the month of such payment, and twelve (12) as its denominator. From and after Tenant’s payment of the True-Up Amount and continuing until a new Estimate Statement is furnished (which Landlord shall have the right to deliver to Tenant at any time, but not more frequently than two times per any Expense Year), Tenant shall pay monthly, with the monthly Base Rent installments, an amount equal to one-twelfth (1/12) of the total Estimated Excess set forth in the previous Estimate Statement delivered by Landlord to Tenant pursuant to which the True-Up Amount was calculated.

4.5 Taxes and Other Charges for Which Tenant Is Directly Responsible.

4.5.1 Tenant shall be liable for and shall pay before delinquency, taxes levied against Tenant’s equipment, furniture, fixtures and any other personal property located in or about the Premises. If any such taxes on Tenant’s equipment, furniture, fixtures and any other personal property are levied against Landlord or Landlord’s property or if the assessed value of Landlord’s property is increased by the inclusion therein of a value placed upon such equipment, furniture, fixtures or any other personal property and if Landlord pays the taxes based upon such increased assessment, which Landlord shall have the right to do regardless of the validity thereof, Tenant shall repay to Landlord, upon demand, the taxes so levied against Landlord or the proportion of such taxes resulting from such increase in the assessment, as the case may be.

4.5.2 If the tenant improvements in the Premises, whether installed and/or paid for by Landlord or Tenant and whether or not affixed to the real property so as to become a part thereof, are assessed for real property tax purposes at a valuation higher than the valuation at which tenant improvements conforming to Landlord’s “building standard” in other space in the Building are assessed, then the Tax Expenses levied against Landlord or the property by reason of such excess assessed valuation shall be deemed to be taxes levied against personal property of Tenant and shall be governed by the provisions of Section 4.5.1 above.

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

4.6 Audit. After delivery to Landlord of at least thirty (30) days’ prior written notice delivered no later than one hundred twenty (120) days after receipt of a Statement, Tenant, at its sole cost and expense through any accountant designated by it, shall have the right to examine and/or audit the books and records evidencing such costs and expenses for the previous one (1) calendar year, during Landlord’s reasonable business hours but not more frequently than once during any calendar year. Any such accounting firm designated by Tenant may not be compensated on a contingency fee basis. Tenant shall have no right to conduct an audit or to give Landlord notice that it desires to conduct an audit at any time an Event of Default exists under the Lease. The results of any such audit (and any negotiations between the parties related thereto) shall be maintained strictly confidential by Tenant and its accounting firm and shall not be disclosed, published or otherwise disseminated to any other party other than to Landlord and its authorized agents. Landlord and Tenant each shall use its best efforts to cooperate in such negotiations and to promptly resolve any discrepancies between Landlord and Tenant in the accounting of such costs and expenses. No subtenant shall have any right to conduct an audit, and no assignee shall conduct an audit for any period during which such assignee was not in possession of the Premises. Tenant’s right to undertake an audit with respect to any calendar year shall expire one hundred twenty (120) days after Tenant’s receipt of the Statement for such calendar year, and such Statement shall be final and binding upon Tenant and shall, as between the parties, be conclusively deemed correct, at the end of such one hundred twenty (120) day period, unless Tenant shall have timely given Landlord written notice of its intention to audit Operating Expenses for the calendar year which is the subject of the Statement. If Tenant timely gives Landlord notice of its intention to audit Operating Expenses, it must commence such audit within thirty (30) days after such notice is delivered to Landlord, and the audit must be completed within ninety (90) days after such notice is delivered to Landlord (provided, however, that in the event Landlord fails to provide Tenant with access to its books and records within thirty (30) days of Tenant’s notice to Landlord, such thirty (30) and ninety (90) day periods shall be extended by one day for each day of such delay). If Tenant does not commence and complete the audit within such periods, the Statement which Tenant elected to audit shall be deemed final and binding upon Tenant and shall, as between the parties, be conclusively deemed correct. If through such audit it is determined that there is a discrepancy of more than five percent (5%) in the amount of Operating Expense payments made by Tenant for such calendar year when compared to the actual Operating Expenses for such year, then Landlord shall reimburse Tenant for the reasonable accounting costs and expenses incurred by Tenant in performing such audit, including Tenant’s outside auditors or accountants (but excluding Tenant’s in-house personnel). However, if through such audit it is determined that there is a discrepancy of five percent (5%) or less, then Tenant shall reimburse Landlord for the reasonable accounting costs and expenses associated with Landlord’s outside accounting firms or auditors (but excluding Landlord’s in-house personnel) in connection with such audit.

Tenant shall not do or permit anything to be done in or about the Premises which will in any way unreasonably obstruct or interfere with the rights of other tenants or occupants of the Building, or use or allow the Premises to be used for any improper, unlawful or objectionable purpose, nor shall Tenant cause, maintain or permit any nuisance in, on or about the Premises. Tenant shall comply with all recorded covenants, conditions, and restrictions now or hereafter affecting the Project.

The right granted to Landlord herein to perform inspections shall not create a duty on Landlord’s part to inspect the Premises, or liability on the part of Landlord for the use, storage, treatment or disposal of Hazardous Materials by Tenant or Tenant’s Agents, it being understood that Tenant shall be solely responsible for all liability in connection therewith.

5.3.6 Landlord shall have the right, but not the obligation, prior or subsequent to any Event of Default by Tenant, without in any way limiting Landlord’s other rights and remedies under this Lease, to enter upon the Premises, or to take such other actions as it deems necessary or advisable, to investigate, clean up, remove or remediate any Hazardous Materials or contamination by Hazardous Materials present on, in, at, under, or emanating from, the Premises, the Building and/or the Project in violation of Tenant’s obligations under this Lease or Tenant’s obligations under any Environmental Laws.

All costs and expenses paid or incurred by Landlord in the exercise of the rights set forth in this Section 5.3 shall be payable by Tenant upon demand.

6.1 Standard Tenant Services. Landlord shall provide the following services on all days (unless otherwise stated below) during the Lease Term.

6.1.1 Subject to limitations imposed by all governmental rules, regulations and guidelines applicable thereto, Landlord shall provide heating and air conditioning (“HVAC”) when necessary for normal comfort for normal office use in the Premises from 8:00 A.M. to 6:00 P.M.

6.2 Overstandard Tenant Use. Tenant shall not, without Landlord’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed, use (i) heat-generating equipment or machines in the Premises, or (ii) machines, other than normal fractional horsepower office machines, or (iii) lighting in the Premises, which equipment, machines and/or lighting may affect the temperature otherwise maintained by the air conditioning system or increase the water normally furnished for the Premises by Landlord pursuant to the terms of Section 6.1 of this Lease. If such consent is given, Landlord shall have the right, following notice to Tenant, to install supplementary facilities and equipment in or servicing the Premises, including supplementary or additional air conditioning and/or metering devices, and the cost thereof, including the cost of installation, operation and maintenance of any supplementary facilities and/or equipment, increased wear and tear on existing equipment and other similar charges, shall

be paid by Tenant to Landlord upon billing by Landlord. If Tenant uses water, electricity, heat or air conditioning in excess of that supplied by Landlord pursuant to Section 6.1 of this Lease, Tenant shall pay to Landlord, upon billing, the cost of such excess consumption, the cost of the installation, operation, and maintenance of equipment which is installed in order to supply such excess consumption, and the cost of the increased wear and tear on existing equipment caused by such excess consumption. Tenant’s use of electricity shall never exceed the capacity of the feeders to the Project or the risers or wiring installation. If Tenant desires to use heat, ventilation or air conditioning during hours other than those for which Landlord is obligated to supply such utilities pursuant to the terms of Section 6.1 of this Lease, Tenant shall give Landlord such prior notice, if any, as Landlord shall from time to time establish as appropriate, of Tenant’s desired use in order to supply such utilities, and Landlord shall supply such utilities to Tenant at such hourly cost to Tenant (which shall be treated as Additional Rent) as Landlord shall from time to time establish. The current rate for such services is $115.00 per hour for after-hours heating, ventilating and air conditioning and $35.00 per hour for air circulation only.

6.3 Interruption of Use. Tenant agrees that, except as otherwise expressly provided herein, Landlord shall not be liable for damages, by abatement of Rent or otherwise, for failure to furnish or delay in furnishing any service (including telephone and telecommunication services), or for any diminution in the quality or quantity thereof, when such failure or delay or diminution is occasioned, in whole or in part, by breakage, repairs, replacements, or improvements, by any strike, lockout or other labor trouble, by inability to secure electricity, gas, water, or other fuel at the Building or Project after reasonable effort to do so, by any riot or other dangerous condition, emergency, accident or casualty whatsoever, by act or default of Tenant or other parties, or by any other cause; and such failures or delays or diminution shall never be deemed to constitute an eviction or disturbance of Tenant’s use and possession of the Premises or relieve Tenant from paying Rent or performing any of its obligations under this Lease. Furthermore, Landlord shall not be liable under any circumstances for a loss of, or injury to, property or for injury to, or interference with, Tenant’s business, including, without limitation, loss of profits, however occurring, through or in connection with or incidental to a failure to furnish any of the services or utilities as set forth in this Article 6. Landlord may comply with voluntary controls or guidelines promulgated by any governmental entity relating to the use or conservation of energy, water, gas, light or electricity or the reduction of automobile or other emissions without creating any liability of Landlord to Tenant under this Lease, provided that the Premises are not thereby rendered untenantable. Notwithstanding any provision contained herein to the contrary, Tenant’s Base Rent shall be abated to the extent that utility services are interrupted for a period of five (5) or more consecutive business days as a result of Landlord’s or its authorized representatives’ gross negligence or willful misconduct; provided Tenant is prevented from using the Premises as a result thereof.

REPAIRS

7.1 Tenant’s Repairs. Tenant shall, at Tenant’s own expense, pursuant to the terms of this Lease, including without limitation Article 8 hereof, keep the Premises, including all improvements, fixtures and furnishings therein and all heating, ventilating, air conditioning, electrical and utility systems that are located within or exclusively serve the Premises, in good order, repair and condition at all times during the Lease Term. In addition, Tenant shall, at Tenant’s own expense, but under the supervision and subject to the prior approval of Landlord, which shall not be unreasonably withheld, conditioned or delayed, and within any reasonable period of time specified by Landlord, pursuant to the terms of this Lease, including without limitation Article 8 hereof, promptly and adequately repair all damage to the Premises and replace or repair all damaged, broken, or worn fixtures and appurtenances, except for damage caused by casualty to, or condemnation of, the Premises, and ordinary wear and tear; provided however, that Landlord shall have the exclusive right, exercisable at Landlord’s option, but not the obligation, upon reasonable prior notice to Tenant, to make such repairs and replacements in the event Tenant fails to timely do so, and Tenant shall pay to Landlord the reasonable cost

thereof, including a percentage of the cost thereof sufficient to reimburse Landlord for all overhead, general conditions, fees and other costs or expenses arising from Landlord’s involvement with such repairs and replacements within thirty (30) days following Landlord’s delivery to Tenant of an invoice therefor, together with reasonable back-up documentation. Landlord may, but shall not be required to, enter the Premises at all reasonable times upon reasonable prior notice to Tenant (which may be oral and which shall not be required in cases of emergency) to make such repairs, alterations, improvements or additions to the Premises or to the Project or to any equipment located in the Project as Landlord shall desire or deem necessary or as Landlord may be required to do by governmental or quasi-governmental authority or court order or decree. Tenant hereby waives any and all rights under and benefits of subsection 1 of Section 1932 and Sections 1941 and 1942 of the California Civil Code or under any similar law, statute, or ordinance now or hereafter in effect.

7.2 Landlord’s Repairs. Subject to the provisions of the immediately preceding paragraph, Articles 11 and 13 of this Lease and Tenant’s obligations under Article 4 to reimburse Landlord for Tenant’s Share of Direct Expenses, Landlord shall maintain or cause to be maintained in good order, condition and repair, the structural portions of the roof, foundations, floors and exterior walls of the Building (including all exterior windows) and the Building plumbing, heating, ventilating, air conditioning and electrical systems serving the Building and the Common Areas; provided, however, that Tenant shall pay the cost of repairs or replacements arising out of the negligence or willful misconduct of Tenant or Tenant’s Agents. Landlord shall be under no obligation to inspect the Premises. Tenant shall promptly report in writing to Landlord any defective condition known to it which Landlord is required to repair.

ARTICLE 8

ADDITIONS AND ALTERATIONS

8.1 Landlord’s Consent to Alterations. Tenant may not make any improvements, alterations, additions or changes (individually, an “Alteration”; collectively, the “Alterations”) to the Premises or to any mechanical, plumbing or HVAC facilities or systems pertaining to the Premises without first procuring the prior written consent of Landlord to such Alterations, which consent shall be requested by Tenant not less than thirty (30) days prior to the commencement thereof, and which consent shall not be unreasonably withheld, conditioned or delayed by Landlord, provided it shall be deemed reasonable for Landlord to withhold its consent to any Alteration which adversely affects the structural portions or the systems or equipment of the Building or is visible from the exterior of the Building. The construction of the initial improvements to the Premises shall be governed by the terms of the Tenant Work Letter and not the terms of this Article 8. Notwithstanding the foregoing to the contrary, Tenant may, at its sole cost and expense and without Landlord’s written consent, perform interior, non-structural alterations or additions to the Premises provided such alterations or additions do not affect the structural components of the Building or Systems and Equipment or require any permit or roof penetrations and the cost of which does not exceed $50,000 in the aggregate over a 12 month period (the “Permitted Alterations”). Tenant shall first notify Landlord at least fifteen (15) days prior to commencing any Permitted Alterations so that Landlord may post a Notice of Non-Responsibility on the Premises.

8.2 Manner of Construction. Landlord may impose, as a condition of its consent to any and all Alterations or repairs of the Premises or about the Premises, such requirements as Landlord in its reasonable discretion may deem desirable, including, but not limited to, the requirement that Tenant utilize for such purposes only contractors, subcontractors, materials, mechanics and materialmen selected by Tenant from a list provided and approved by Landlord. Notwithstanding the foregoing, with respect to construction of the initial Tenant Improvements as described on Exhibit B attached hereto, Landlord hereby approves TCB Builders, Inc. as Tenant’s contractor and further approves all architects, engineers, project managers, subcontractors, mechanics and materialmen and other consultants selected by TCB Builders, Inc. (the “TCB Subcontractors”) provided each such TCB Subcontractor utilizes union labor and is a reputable, licensed company doing business in San Francisco, California. Tenant shall provide Landlord with a list of all TCB Subcontractors prior to commencement of any construction in the Premises. Notwithstanding anything to the contrary contained herein, in the event that Tenant desires access to the Building risers in connection with the exercise of its rights pursuant to this paragraph, then Tenant shall be required to utilize the services of Landlord’s designated Building riser management company. The contractor or person selected by Tenant or Landlord to make Alterations must declare to Landlord in writing that he or she belongs to a local trade union, and must be approved in writing by Landlord prior to commencement of any work. If a subcontractor is selected to perform the work, the general contractor must

warrant and represent to Landlord in writing that such subcontractor belongs to a local trade union. If such Alterations will involve the use of or disturb Hazardous Materials existing in the Premises, Tenant shall comply with Landlord’s rules and regulations concerning such Hazardous Materials. Tenant shall construct such Alterations and perform such repairs in a good and workmanlike manner, in conformance with any and all Applicable Laws, pursuant to a valid building permit, issued by the City of San Francisco, and in conformance with Landlord’s reasonable construction rules and regulations. In the event Tenant performs any Alterations in the Premises which require or give rise to governmentally required changes to the “Base Building,” as that term is defined below, then Landlord shall, at Tenant’s expense, make such changes to the Base Building. The “Base Building” shall include the structural portions of the Building, and the public restrooms and the systems and equipment located in the internal core of the Building on the floor or floors on which the Premises are located. In performing the work of any such Alterations, Tenant shall have the work performed in such manner so as not to obstruct access to the Project or any portion thereof, for any other tenant of the Project, and so as not to obstruct the business of Landlord or other tenants in the Project. Tenant shall not use (and upon notice from Landlord shall cease using) contractors, services, workmen, labor, materials or equipment that, in Landlord’s reasonable judgment, would disturb labor harmony with the workforce or trades engaged in performing other work, labor or services in or about the Building or the Common Areas. In addition to Tenant’s obligations under Article 9 of this Lease, upon completion of any Alterations, Tenant agrees to cause a Notice of Completion to be recorded in the office of the Recorder of the County of San Francisco in accordance with Section 3093 of the Civil Code of the State of California or any successor statute, and Tenant shall deliver to the Project management office a reproducible copy of the “as built” drawings of the Alterations as well as all permits, approvals and other documents issued by any governmental agency in connection with the Alterations.

8.3 Payment for Improvements. If payment is made directly to contractors, Tenant shall comply with Landlord’s reasonable requirements for final lien releases and waivers in connection with Tenant’s payment for work to contractors. If Tenant requests any alteration, repair or improvement work to be performed by Landlord, Tenant shall pay to Landlord a percentage not to exceed seven percent (7%) if the total cost of such work is equal to or less than Ten Thousand Dollars ($10,000) and, if the total cost exceeds Ten Thousand Dollars ($10,000), then such percentage shall not exceed five percent (5%) of the cost of such work sufficient to compensate Landlord for all overhead, general conditions, fees and other costs and expenses arising from Landlord’s involvement with such work. If Tenant does not request Landlord to perform any such work, Tenant shall reimburse Landlord for Landlord’s reasonable, actual, out-of-pocket costs and expenses actually incurred in connection with Landlord’s review of such work within thirty (30) days of Landlord’s submission to Tenant of an invoice therefor, together with reasonable back-up documentation.

8.4 Construction Insurance. In addition to the requirements of Article 10 of this Lease, in the event that Tenant makes any Alterations, prior to the commencement of such Alterations, Tenant shall provide Landlord with evidence that Tenant or Tenant’s contractor carries “Builder’s All Risk” insurance in an amount reasonably approved by Landlord covering the construction of such Alterations, and such other insurance as Landlord may reasonably require, it being understood and agreed that all of such Alterations shall be insured by Tenant pursuant to Article 10 of this Lease immediately upon completion thereof. In addition, for Alterations the estimated cost of which exceeds $50,000, Landlord may, in its discretion, require Tenant to obtain a lien and completion bond or some alternate form of security satisfactory to Landlord in an amount sufficient to ensure the lien-free completion of such Alterations and naming Landlord as a co-obligee. Notwithstanding the foregoing, so long as Tenant is the entity initially named in this Lease, then the lien and completion bond that may be required pursuant to the immediately preceding sentence shall only be required, if at all, in the event Tenant’s Alterations are estimated to cost in excess of $200,000. No lien or completion bond shall be required in connection with construction of the Tenant Improvements pursuant to Exhibit B.

8.5 Landlord’s Property. All Alterations, improvements, fixtures, equipment and/or appurtenances which may be installed or placed in or about the Premises, from time to time, shall be at the sole cost of Tenant and, except for Tenant’s Property (as defined in Section 15.2), shall be and become the property of Landlord. Furthermore, Landlord may, by written notice to Tenant at the time Landlord consents to any Alteration, require Tenant, at Tenant’s expense, to (i) remove any Alterations in the Premises, and/or (ii) remove any “Non Standard Tenant Improvements,” as that term is defined in Section 2.4 of the Tenant Work Letter, located within the Premises and replace the same with then existing “Building Standard Tenant Improvements,” as that term is defined in Section 2.3 of the Tenant Work Letter, and to repair any damage to the Premises and Building caused by such removal and return the affected portion of the Premises to a building standard tenant improved condition as reasonably determined by Landlord; provided, however, that in no event

shall Tenant be required to remove any of the Tenant Improvements (other than telephone, data and other cabling and wiring and other than as set forth in Section 15.2 below). If Tenant fails to complete such removal and/or to repair any damage caused by the removal of any Alterations in the Premises, and/or fails to return the affected portion of the Premises to a building standard tenant improved condition as reasonably determined by Landlord, then at Landlord’s option, either (A) Tenant shall be deemed to be holding over in the Premises and Rent shall continue to accrue in accordance with the terms of Article 16 below, until such work shall be completed, or (B) Landlord may do so and may charge the cost thereof to Tenant. Tenant hereby agrees to protect, defend, indemnify and hold Landlord harmless from any liability, cost, damages, obligation, expense or claim (including reasonable attorneys’ fees) in any manner relating to the installation, placement, removal or financing of any such Alterations, improvements, fixtures and/or equipment placed or installed in, on or about the Premises by or on behalf of Tenant, which obligations of Tenant shall survive the expiration or earlier termination of this Lease.

8.6 Wi-Fi Network. Without limiting the generality of the foregoing, Tenant shall be permitted to install wireless intranet, Internet and communications network (“Wi-Fi Network”) in the Premises for the use by Tenant and its employees, and, to the extent permitted by Applicable Laws, the same shall be subject to the provisions of this Section 8.6 (in addition to the other provisions of this Article 8). Tenant shall, in accordance with Section 15.2 below, remove the Wi-Fi Network from the Premises prior to the termination of the Lease. Tenant shall use the Wi-Fi Network so as not to cause any interference to other tenants in the Building or Project or with any other tenant’s communication equipment, and not to damage the Building or Project or interfere with the normal operation of the Building or Project and Tenant hereby agrees to indemnify, defend and hold Landlord harmless from and against any and all claims, costs, damages, expenses and liabilities (including reasonable attorneys’ fees) arising out of Tenant’s failure to comply with the provisions of this Section 8.6, except to the extent same is caused by the gross negligence or willful misconduct of Landlord and which is not covered by the insurance carried by Tenant under this Lease (or which would not be covered by the insurance required to be carried by Tenant under this Lease). Should any interference occur, Tenant shall take all necessary steps as soon as reasonably possible and no later than three (3) business days following such occurrence to correct such interference. If such interference continues after such three (3) business day period, Tenant shall immediately cease operating such Wi-Fi Network until such interference is corrected or remedied to Landlord’s satisfaction. Tenant acknowledges that Landlord has granted and/or may grant telecommunication rights to other tenants and occupants of the Building and to telecommunication service providers and in no event shall Landlord be liable to Tenant for any interference of the same with such Wi-Fi Network. Landlord makes no representation that the Wi-Fi Network will be able to receive or transmit communication signals without interference or disturbance. Tenant shall (i) be solely responsible for any damage caused as a result of the Wi-Fi Network, (ii) promptly pay any tax, license or permit fees charged pursuant to any laws or regulations in connection with the installation, maintenance or use of the Wi-Fi Network and comply with all precautions and safeguards recommended by all governmental authorities, and (iii) pay for all necessary repairs, replacements to or maintenance of the Wi-Fi Network. Should Landlord be required to retain professionals to research any interference issues that may arise and to confirm Tenant’s compliance with the terms of this Section 8.6, Landlord shall retain such professionals at commercially reasonable rates, and Tenant shall reimburse Landlord within thirty (30) days following submission to Tenant of an invoice from Landlord, together with reasonable back-up documentation, which costs shall not exceed $1,000 per year (except in the event of an Event of Default by Tenant hereunder). This reimbursement obligation is independent of any rights or remedies Landlord may have in the event of a breach or default by Tenant under this Lease.

ARTICLE 9

COVENANT AGAINST LIENS

Tenant shall keep the Project and Premises free from any liens or encumbrances arising out of the work performed, materials furnished or obligations incurred by or on behalf of Tenant, and shall protect, defend, indemnify and hold Landlord harmless from and against any claims, liabilities, judgments, expenses or costs (including, without limitation, reasonable attorneys’ fees and costs) arising out of same or in connection therewith. Tenant shall give Landlord notice at least twenty (20) days prior to the commencement of any such work on the Premises (or such additional time as may be necessary under Applicable Laws) to afford Landlord the opportunity of posting and recording appropriate notices of non-responsibility. Tenant shall remove any such lien or encumbrance by bond or otherwise within ten (10) days after notice by Landlord, and if Tenant shall fail to do so, Landlord may pay the amount necessary to

remove such lien or encumbrance, without being responsible for investigating the validity thereof. The amount so paid shall be deemed Additional Rent under this Lease payable upon demand, without limitation as to other remedies available to Landlord under this Lease. Nothing contained in this Lease shall authorize Tenant to do any act which shall subject Landlord’s title to the Building or Premises to any liens or encumbrances whether claimed by operation of law or express or implied contract. Any claim to a lien or encumbrance upon the Building or Premises arising in connection with any such work or respecting the Premises not performed by or at the request of Landlord shall be null and void, or at Landlord’s option shall attach only against Tenant’s interest in the Premises and shall in all respects be subordinate to Landlord’s title to the Project, Building and Premises.

ARTICLE 10

INSURANCE

10.1 Indemnification and Waiver. Except to the extent caused by Landlord’s gross negligence or willful misconduct, Tenant hereby assumes all risk of damage to property or injury to persons in, upon or about the Premises, the Building and/or the Project, from any cause whatsoever (including, without limitation, personal injuries occurring in, on, upon or about the Premises, the Building and/or the Project) and agrees that Landlord, its partners, representatives, members, agents, employees, directors, officers, successors and assign (collectively, “Landlord Parties”) shall not be liable for, and are hereby released from any responsibility for, any damage either to person or property or resulting from the loss of use thereof, which damage is sustained by Tenant or by other persons claiming through Tenant from any cause whatsoever. Tenant shall indemnify, defend, protect, and hold harmless the Landlord Parties from any and all losses, costs, damages, claims, judgments, expenses and liability (including without limitation court costs and reasonable attorneys’ fees) (individually, a “Claim”; collectively, “Claims”) incurred in connection with or arising from any cause in, on or about the Premises, the Building and/or the Project, including, without limiting the generality of the foregoing: (i) any violation by Tenant or Tenant’s Agents of any Applicable Laws, including, without limitation, any Environmental Laws, (ii) the use or occupancy or manner of use or occupancy of the Premises, the Building and/or the Project by Tenant or Tenant’s Agents or any person or entity claiming through or under Tenant, (iii) the passive negligence or active negligence, to the extent active negligence is not deemed to be gross negligence, of Landlord, (iv) any acts, omissions or negligence of Tenant or of any person claiming by, through or under Tenant, or of Tenant’s Agents or any such person, in, on or about the Project or (v) any default by Tenant or Tenant’s Agents in the observance or performance of any of the terms, covenants or conditions of this Lease, either prior to, during, or after the expiration of the Lease Term, provided that the terms of the foregoing indemnity shall not apply to any Claims arising from the gross negligence or willful misconduct of Landlord or any other Landlord Parties. In the event any action or proceeding is brought against Landlord for any Claim against which Tenant is obligated to indemnify Landlord hereunder, Tenant upon notice from Landlord shall defend such action or proceeding at Tenant’s sole expense by counsel selected by Landlord. The provisions of this Section 10.1 shall survive the expiration or sooner termination of this Lease. Notwithstanding the provisions of this Section 10.1 above to the contrary, Tenant’s indemnity of Landlord and the Landlord Parties shall not apply to: (i) any claims to the extent resulting from the gross negligence or willful misconduct of the Landlord Parties and not insured or required to be insured by Tenant under this Lease (collectively, the “Excluded Claims”); or (ii) any loss of or damage to Landlord’s property to the extent Landlord has waived such loss or damage pursuant to Section 10.5 below. In addition, Landlord shall indemnify, defend, protect and hold Tenant harmless from all such Excluded Claims, except for (A) any loss or damage to Tenant’s property to the extent Tenant has waived such loss or damage pursuant to Section 10.5 below, and (B) any lost profits, loss of business or other consequential damages.

10.2 Tenant’s Compliance With Landlord’s Fire and Casualty Insurance. Tenant shall, at Tenant’s expense, comply with all insurance company requirements pertaining to the use of the Premises. Tenant shall not cause or permit anything to be done in, upon or about the Premises which would in any way increase the premium for, cause the cancellation of or otherwise affect any insurance carried by Landlord in connection with the Project. Without limiting Landlord’s remedies for Tenant’s breach of the foregoing covenant, if Tenant’s conduct or use of the Premises causes any increase in the premium for such insurance policies, then Tenant shall reimburse Landlord for any such increase promptly upon being billed therefor. Tenant, at Tenant’s sole cost and expense, shall comply with all rules, orders, regulations or requirements of the American Insurance Association (formerly the National Board of Fire Underwriters) and any similar body.

10.3 Tenant’s Insurance. Throughout the Term of the Lease, Tenant shall maintain the following coverages in the following amounts.

10.3.1 Commercial General Liability Insurance covering the insured against claims of bodily injury, personal injury and property damage (including loss of use thereof) arising out of Tenant’s operations, and contractual liabilities (covering the performance by Tenant of its indemnity agreements) and covering the insuring provisions of this Lease and the performance by Tenant of the indemnity agreements set forth in Section 10.1 of this Lease, for limits of liability not less than:

10.3.5 Comprehensive Automobile Liability Insurance having a combined single limit of not less than One Million Dollars ($1,000,000) per occurrence and insuring Tenant against liability for claims arising out of ownership, maintenance or use of any owned, hired or non-owned automobiles.

10.4 Form of Policies. The minimum limits of policies of insurance required of Tenant under this Lease shall in no event limit the liability of Tenant under this Lease. The General Liability insurance policy shall (i) name Landlord, Landlord’s lender, and any other party the Landlord so specifies, as an additional insured, including Landlord’s managing agent, if any; (ii) specifically cover the liability assumed by Tenant under this Lease, including, but not limited to, Tenant’s obligations under Section 10.1 of this Lease; (iii) be issued by an insurance company having a rating of not less than A-:IX in Best’s Insurance Guide or which is otherwise reasonably acceptable to Landlord and licensed to do business in the State of California; (iv) be primary insurance as to all claims thereunder and provide that any insurance carried by Landlord is excess and is non-contributing with any insurance requirement of Tenant; (v) be in form and content reasonably acceptable to Landlord; and (vi) provide that said insurance shall not be canceled or coverage

changed unless thirty (30) days’ prior written notice shall have been given to Landlord and any mortgagee of Landlord. Tenant shall deliver said policy or policies or certificates thereof to Landlord on or before the Lease Commencement Date and, thereafter, at least thirty (30) days before the expiration dates thereof. In the event Tenant shall fail to procure such insurance, or to deliver such policies or certificate, Landlord may, at its option, procure such policies for the account of Tenant, and the cost thereof shall be paid to Landlord within five (5) days after delivery to Tenant of bills therefor. At Tenant’s option, Tenant may provide the coverages required under this Article 10 through blanket policies of insurance covering Tenant’s other properties, so long as the coverage required under this Lease with respect to the Premises, Building and Project is not reduced or impaired as a result thereof (including as a result of any claims made or aggregate limits with respect to such other properties) including deductibles, retentions or self-insurance applicable thereto.

10.5 Subrogation. Landlord and Tenant intend that their respective property loss risks shall be borne by reasonable insurance carriers to the extent above provided, and Landlord and Tenant hereby agree to look solely to, and seek recovery only from, their respective insurance carriers in the event of a property loss to the extent that such coverage is agreed to be provided hereunder. The parties each hereby waive all rights and claims against each other for such losses, and waive all rights of subrogation of their respective insurers, provided such waiver of subrogation shall not affect the right to the insured to recover thereunder. The parties agree that their respective insurance policies are now, or shall be, endorsed such that the waiver of subrogation shall not affect the right of the insured to recover thereunder.

10.6 Additional Insurance Obligations. Tenant shall carry and maintain during the entire Lease Term, at Tenant’s sole cost and expense, increased amounts of the insurance required to be carried by Tenant pursuant to this Article 10 and such other reasonable types of insurance coverage and in such reasonable amounts covering the Premises and Tenant’s operations therein, as may be reasonably requested by Landlord.

ARTICLE 11

DAMAGE AND DESTRUCTION

11.1 Repair of Damage to Premises by Landlord. Tenant shall promptly notify Landlord of any damage to the Premises resulting from fire or any other casualty. If the Premises or any Common Areas necessary to Tenant’s use or access to the Premises shall be damaged by fire or other casualty, Landlord shall promptly and diligently, subject to reasonable delays for insurance adjustment or other matters beyond Landlord’s reasonable control, and subject to all other terms of this Article 11, restore the Base Building and such Common Areas. Such restoration shall be to substantially the same condition of the Base Building and the Common Areas prior to the casualty, except for modifications required by zoning and building codes and other Applicable Laws or by the holder of a mortgage on the Building or Project or any other modifications to the Common Areas deemed desirable by Landlord. Following the occurrence of any damage to the Premises, Landlord may elect by written notice (the “Landlord Repair Notice”) to Tenant to repair such damage and restore the Tenant Improvements and Original Improvements, in which case Tenant shall assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under Tenant’s insurance required under items (ii) and (iii) of Section 10.3.2 of this Lease, and thereafter Landlord shall repair any injury or damage to the Tenant Improvements and the Original Improvements installed in the Premises and shall return such Tenant Improvements and Original Improvements to their original condition; provided that if the cost of such repair by Landlord exceeds the amount of insurance proceeds received by Landlord from Tenant’s insurance carrier, as assigned by Tenant in accordance with the foregoing, the cost of such repairs shall be paid by Tenant to Landlord prior to Landlord’s commencement of repair of the damage. In the event that Landlord does not deliver a Landlord Repair Notice within sixty (60) days following the date the casualty becomes known to Landlord, Tenant shall, at its sole cost and expense, repair any injury or damage to the Tenant Improvements and the Original Improvements installed in the Premises and shall return such Tenant Improvements and Original Improvements to their original condition. Whether or not Landlord delivers a Landlord Repair Notice, prior to the commencement of construction, Tenant shall submit to Landlord, for Landlord’s review and approval, all plans, specifications and working drawings relating thereto, and Landlord shall select the contractors to perform such improvement work. Landlord shall not be liable for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant’s business resulting in any way from such damage or the repair thereof; provided however, that if such fire or other casualty shall have damaged the Premises or a portion thereof or the Common Areas necessary to Tenant’s occupancy, Landlord shall allow Tenant a proportionate abatement of Rent to the extent Landlord is reimbursed from the proceeds of rental interruption insurance purchased by

Landlord as part of Operating Expenses, during the time and to the extent and in the proportion that the Premises or such portion thereof are unfit for occupancy for the purposes permitted under this Lease, and not occupied by Tenant as a result thereof; provided, further, however, that if the damage or destruction is due to the negligence or willful misconduct of Tenant or any of Tenant’s Agents, Tenant shall be responsible for any reasonable, applicable insurance deductible (which shall be payable to Landlord upon demand) and there shall be no rent abatement. In the event that Landlord shall not deliver the Landlord Repair Notice, Tenant’s right to rent abatement pursuant to the preceding sentence shall terminate as of the date which is reasonably determined by Landlord to be the date Tenant should have completed repairs to the Premises assuming Tenant used reasonable due diligence in connection therewith.

11.2 Landlord’s Option to Repair. Notwithstanding the terms of Section 11.1 of this Lease, Landlord may elect not to rebuild and/or restore the Premises, Building and/or Project, and instead terminate this Lease, by notifying Tenant in writing of such termination within sixty (60) days after the date of discovery of the damage, such notice to include a termination date giving Tenant sixty (60) days to vacate the Premises, but Landlord may so elect only if the Building or Project shall be damaged by fire or other casualty or cause, whether or not the Premises are affected, and one or more of the following conditions is present: (i) in Landlord’s reasonable judgment, repairs cannot reasonably be completed within one hundred eighty (180) days after the date of discovery of the damage (when such repairs are made without the payment of overtime or other premiums); (ii) the holder of any mortgage on the Building or Project or ground lessor with respect to the Building or Project shall require that the insurance proceeds or any portion thereof be used to retire the mortgage debt, or shall terminate the ground lease, as the case may be; (iii) the damage is not fully covered by Landlord’s insurance policies; (iv) Landlord decides to rebuild the Building or Common Areas so that they will be substantially different structurally or architecturally; or (v) the damage occurs during the last twelve (12) months of the Lease Term. In the event this Lease is terminated in accordance with the terms of this Section 11.2, then Tenant shall assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under Tenant’s insurance required under items (ii) and (iii) of Section 10.3.2 of this Lease.

11.3 Tenant’s Termination Option. If (i) Landlord does not elect to terminate this Lease pursuant to Landlord’s termination right as provided in Section 11.2 above, (ii) the damage is not the result of Tenant’s negligence or willful misconduct, (iii) the damage materially interferes with Tenant’s access to or usage of the Premises and Tenant does not thereafter use the Premises, and (iv) Landlord’s restoration work cannot, in the reasonable opinion of Landlord’s licensed contractor, be substantially completed within one hundred eighty (180) days after the date of damage, then Tenant may elect to terminate this Lease by delivering written notice thereof to Landlord within thirty (30) days after Tenant’s receipt of Landlord’s notice of the damage, which termination shall be effective as of the date which is thirty (30) days after the date such termination notice is delivered to Landlord. Furthermore, in the event Landlord’s restoration work has not been substantially completed within one hundred eighty (180) days after the date of damage and the then condition of the Premises or the Building materially interferes with Tenant’s access to or usage of the Premises, then Tenant may elect to terminate this Lease by delivering written notice thereof to Landlord at any time prior to the substantial completion of such restoration work, which termination shall be effective as of the date which is thirty (30) days after the date such termination notice is delivered to Landlord unless, within such thirty (30) day period, the restoration work has been substantially completed.

11.4 Waiver of Statutory Provisions. The provisions of this Lease, including this Article 11, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises, the Building or the Project, and any statute or regulation of the State of California, including, without limitation, Sections 1932(2), 1933(4), 1941 and 1942 of the California Civil Code, with respect to any rights or obligations concerning damage or destruction in the absence of an express agreement between the parties, and any other statute or regulation, now or hereafter in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises, the Building or the Project.

ARTICLE 12

NONWAIVER

No provision of this Lease shall be deemed waived by either party hereto unless expressly waived in a writing signed thereby. The waiver by either party hereto of any breach of any term, covenant or condition herein contained

shall not be deemed to be a waiver of any subsequent breach of same or any other term, covenant or condition herein contained. The subsequent acceptance of Rent hereunder by Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of any term, covenant or condition of this Lease, other than the failure of Tenant to pay the particular Rent so accepted, regardless of Landlord’s knowledge of such preceding breach at the time of acceptance of such Rent. No acceptance of a lesser amount than the Rent herein stipulated shall be deemed a waiver of Landlord’s right to receive the full amount due, nor shall any endorsement or statement on any check or payment or any letter accompanying such check or payment be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the full amount due. No receipt of monies by Landlord from Tenant after the termination of this Lease shall in any way alter the length of the Lease Term or of Tenant’s right of possession hereunder, or after the giving of any notice shall reinstate, continue or extend the Lease Term or affect any notice given Tenant prior to the receipt of such monies, it being agreed that after the service of notice or the commencement of a suit, or after final judgment for possession of the Premises, Landlord may receive and collect any Rent due, and the payment of said Rent shall not waive or affect said notice, suit or judgment.

ARTICLE 13

CONDEMNATION

If the whole or any part of the Premises, Building or Project shall be taken by power of eminent domain or condemned by any competent authority for any public or quasi-public use or purpose, or if any adjacent property or street shall be so taken or condemned, or reconfigured or vacated by such authority in such manner as to require the use, reconstruction or remodeling of any part of the Premises, Building or Project, or if Landlord shall grant a deed or other instrument in lieu of such taking by eminent domain or condemnation, Landlord shall have the option to terminate this Lease effective as of the date possession is required to be surrendered to the authority. If more than ten percent (10%) of the rentable square feet of the Premises is taken or the taking would prevent or materially interfere with Tenant’s use of the Premises, Tenant shall have the option to terminate this Lease effective as of the date possession is required to be surrendered to the authority. Tenant shall not because of any such taking assert any claim against Landlord or the authority for any compensation because of such taking and Landlord shall be entitled to the entire award or payment in connection therewith, except that Tenant shall have the right to file any separate claim available to Tenant for any taking of Tenant’s personal property and fixtures belonging to Tenant and removable by Tenant upon expiration of the Lease Term pursuant to the terms of this Lease, and for moving expenses, so long as such claims do not diminish the award available to Landlord, its ground lessor with respect to the Building or Project or its mortgagee, and such claim is payable separately to Tenant. All Rent shall be apportioned as of the date of such termination. If any part of the Premises shall be taken, and this Lease shall not be terminated in connection therewith, the Rent shall be proportionately abated. Tenant hereby waives any and all rights it might otherwise have pursuant to Section 1265.130 of the California Code of Civil Procedure.

ARTICLE 14

ASSIGNMENT AND SUBLETTING

14.1 Transfers. Tenant shall not, without the prior written consent of Landlord, assign, mortgage, pledge, hypothecate, encumber, or permit any lien to attach to, or otherwise transfer, this Lease or any interest hereunder, permit any assignment, or other transfer of this Lease or any interest hereunder by operation of law, sublet the Premises or any part thereof, or enter into any license or concession agreements or otherwise permit the occupancy or use of the Premises or any part thereof by any persons other than Tenant and its employees and contractors (all of the foregoing are hereinafter sometimes referred to individually as a “Transfer” and collectively as “Transfers” and any person to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a “Transferee”). If Tenant desires Landlord’s consent to any Transfer, Tenant shall notify Landlord in writing, which notice (the “Transfer Notice”) shall include (i) the proposed effective date of the Transfer, which shall not be less than fourteen (14) days nor more than one hundred eighty (180) days after the date of delivery of the Transfer Notice, (ii) a description of the portion of the Premises to be transferred (the “Subject Space”), (iii) all of the terms of the proposed Transfer and the consideration therefor, including calculation of the “Transfer Premium”, as that term is defined in Section 14.3 below, in connection with such Transfer, the name and address of the proposed Transferee, and an executed copy of all documentation

effectuating the proposed Transfer, including all operative documents to evidence such Transfer, and (iv) current financial statements of the proposed Transferee certified by an officer, partner or owner thereof, business credit and personal references and history of the proposed Transferee and any other information reasonably required by Landlord which will enable Landlord to determine the financial responsibility, character, and reputation of the proposed Transferee, nature of such Transferee’s business and proposed use of the Subject Space. Any Transfer made without Landlord’s prior written consent shall, at Landlord’s option, be null, void and of no effect, and shall, at Landlord’s option, constitute a default by Tenant under this Lease. Whether or not Landlord consents to any proposed Transfer, Tenant shall reimburse Landlord for its out-of-pocket review and processing fees which shall not exceed Two Thousand Five Hundred Dollars ($2,500) in any one instance, and Tenant shall also reimburse Landlord for any reasonable out-of-pocket professional fees (including, without limitation, attorneys’, accountants’, architects’, engineers’ and consultants’ fees) incurred by Landlord, within thirty (30) days after written request therefor by Landlord accompanied by reasonable back-up documentation. Notwithstanding anything to the contrary contained in this Section 14.1, so long as Tenant delivers to Landlord (i) at least fifteen (15) business days prior written notice of its intention to assign or sublease the Premises to any Related Entity, which notice shall set forth the name of the Related Entity, (ii) a copy of the proposed agreement pursuant to which such assignment or sublease shall be effectuated, and (iii) such other information concerning the Related Entity as Landlord may reasonably require, including without limitation, information regarding any change in the proposed use of any portion of the Premises and any financial information with respect to such Related Entity, and so long as (a) any change in the proposed use of the subject portion of the Premises is in conformance with the uses permitted to be made under this Lease and do not involve the use or storage of any Hazardous Materials (other than nominal amounts of ordinary household cleaners, office supplies and janitorial supplies which are not regulated by any environmental laws), and (b) at the time of the proposed assignment or sublease, the net profits and financial condition of the Related Entity is reasonably adequate and sufficient in relation to the then remaining obligations of Tenant under this Lease (as reasonably determined by Landlord), then Tenant may assign this Lease or sublease any portion of the Premises (1) to any Related Entity, or (2) in connection with any merger, consolidation or sale of substantially all of the assets of Tenant, without having to obtain the prior written consent of Landlord thereto (each such transfer shall be referred to herein as a “Permitted Transfer”). Any Permitted Transfer shall in no way relieve Tenant of any liability Tenant may have under this Lease and such assignee or sublessee shall be jointly and severally liable with Tenant hereunder. For purposes of this Section 14.1, the term “Related Entity” shall mean any entity controlled by, under control with, or in control of Tenant and such entity shall have at least substantially the same net worth as Tenant. The term “control” as used in the immediately preceding sentence shall mean having direct ownership of fifty percent (50%) or more of the ownership interests of an entity and having the ability to direct the management and policies of such entity.

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

14.2.1 The Transferee is engaged in a business which is not consistent with the quality of the Building or the Project;

14.2.2 The Transferee intends to use the Subject Space for purposes which are not permitted under this Lease;

14.2.3 The Transferee is either a governmental agency or instrumentality thereof;

14.2.4 The Transferee is not a party of reasonable financial worth and/or financial stability in light of the responsibilities to be undertaken in connection with the Transfer on the date consent is requested and in the event of an assignment of the Lease, then in no event shall the Transferee have a financial net worth less than Tenant’s net worth as of the date of this Lease;

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

14.2.6 The terms of the proposed Transfer will allow the Transferee to exercise a right of renewal, right of expansion, right of first offer, or other similar right held by Tenant;

14.2.7 Either the proposed Transferee, or any person or entity which directly or indirectly, controls, is controlled by, or is under common control with, the proposed Transferee, (i) occupies space in the Project at the time of the request for consent, or (ii) is negotiating with Landlord to lease space in the Project at such time, or (iii) has negotiated with Landlord during the one hundred eighty (180)-day period immediately preceding the Transfer Notice; provided in each event that Landlord has space in the Building reasonably capable of satisfying the proposed Transferee’s space requirement;

14.2.8 In Landlord’s reasonable judgment, the use of the Premises by the proposed Transferee (i) would not be comparable to the types of office uses of other tenants in the Project, (ii) would entail Alterations which would lessen the value of the Tenant Improvements in the Premises, (iii) would result in more than allowed density of occupants per square foot of the Premises, as set forth in Section 5.2 above, (iv) would increase the burden on elevators or other Building systems or equipment over the burden thereon prior to the proposed Transfer, or (v) would require increased services by Landlord;

14.2.9 An Event of Default, or an event which with the giving of notice or the passage of time, or both, would constitute an Event of Default, of the terms, covenants and conditions of this Lease has occurred;

14.2.10 The form of the proposed sublease and consent is not in a form reasonably satisfactory to Landlord and/or does not comply with the applicable provisions of this Article 14; or

14.2.11 The rental and other terms and conditions of the sublease are the same as those contained in the proposed sublease furnished to Landlord pursuant to Section 14.1.

If Landlord consents to any Transfer pursuant to the terms of this Section 14.2 (and does not exercise any recapture rights Landlord may have under Section 14.4 of this Lease), Tenant may within six (6) months after Landlord’s consent, but not later than the expiration of said six-month period, enter into such Transfer of the Premises or portion thereof, upon substantially the same terms and conditions as are set forth in the Transfer Notice furnished by Tenant to Landlord pursuant to Section 14.1 of this Lease, provided that if there are any changes in the terms and conditions from those specified in the Transfer Notice (i) such that Landlord would initially have been entitled to refuse its consent to such Transfer under this Section 14.2, or (ii) which would cause the proposed Transfer to be more favorable to the Transferee than the terms set forth in Tenant’s original Transfer Notice, Tenant shall again submit the Transfer to Landlord for its approval and other action under this Article 14 (including Landlord’s right of recapture, if any, under Section 14.4 of this Lease). Notwithstanding anything to the contrary herein, Tenant hereby expressly waives all rights provided under California Civil Code Section 1995.310, and any similar or successor statute or law in effect or any amendment thereof during the Lease Term and Tenant hereby acknowledges and agrees that, if it is determined by a court of law that Landlord has withheld or delayed its consent to a proposed sublet or assignment of all or any portion of Tenant’s interest in this Lease in a manner which results in a breach of Landlord’s obligations under this Article 14, then the sole remedy of Tenant and any proposed Transferee as a result of such breach shall be to seek a declaratory judgment and/or injunctive relief. Tenant shall indemnify, defend and hold harmless Landlord from any and all Claims involving any third party or parties (including without limitation Tenant’s proposed subtenant or assignee) who claim they were damaged by Landlord’s wrongful withholding or conditioning of Landlord’s consent.

14.3 Transfer Premium. If Landlord consents to a Transfer, as a condition thereto which the parties hereby agree is reasonable, Tenant shall pay to Landlord fifty percent (50%) of any “Transfer Premium,” as that term is defined in this Section 14.3, received by Tenant from such Transferee. “Transfer Premium” shall mean all rent, additional rent or other consideration payable by such Transferee in connection with the Transfer in excess of the Rent and Additional Rent payable by Tenant under this Lease during the term of the Transfer on a per rentable square foot basis if less than all of the Premises is transferred, after deducting the reasonable expenses incurred by Tenant for (i) any reasonable Alterations to the Premises made by Tenant (and consented to by Landlord) in connection with the Transfer, (ii) any free base rent reasonably provided to the Transferee, and (iii) any brokerage commissions customary in the industry in connection with the Transfer (collectively, “Tenant’s Costs”). “Transfer Premium” shall also include, but not be limited

to, key money, bonus money or other cash consideration paid by Transferee to Tenant in connection with such Transfer, and any payment in excess of fair market value for services rendered by Tenant to Transferee or for assets, fixtures, inventory, equipment, or furniture transferred by Tenant to Transferee in connection with such Transfer. For the purposes of calculating the Transfer Premium on a monthly basis, (A) Tenant’s Costs shall be amortized over the remaining term of this Lease, and (B) the Rent paid for the Subject Space shall be computed after adjusting such rent to the actual effective rent to be paid, taking into consideration any and all leasehold concessions granted in connection therewith, including, but not limited to, any rent credit and tenant improvement allowance. For purposes of calculating any such effective rent all such concessions shall be amortized on a straight-line basis over the relevant term.

14.4 Landlord’s Option as to Subject Space. Notwithstanding anything to the contrary contained in this Article 14, in the event Tenant desires to sublease the entire Premises for the then remaining Term of the Lease, then Landlord shall have the option, by giving written notice to Tenant within twenty (20) days after receipt of any Transfer Notice, to recapture the Premises. Such recapture shall cancel and terminate this Lease as of the date stated in the Transfer Notice as the effective date of the proposed Transfer. If Landlord declines, or fails to elect in a timely manner, to recapture the Premises under this Section 14.4, then, provided Landlord has consented to the proposed Transfer, Tenant shall be entitled to proceed to transfer the Premises to the proposed Transferee, subject to provisions of this Article 14.

14.5 Effect of Transfer. If Landlord consents to a Transfer, (i) the terms and conditions of this Lease shall in no way be deemed to have been waived or modified, (ii) such consent shall not be deemed consent to any further Transfer by either Tenant or a Transferee, (iii) Tenant shall deliver to Landlord, promptly after execution, an original executed copy of all documentation pertaining to the Transfer in form reasonably acceptable to Landlord, (iv) Tenant shall furnish upon Landlord’s request a complete statement, certified by an independent certified public accountant, or Tenant’s chief financial officer, setting forth in detail the computation of any Transfer Premium Tenant has derived and shall derive from such Transfer, and (v) no Transfer relating to this Lease or agreement entered into with respect thereto, whether with or without Landlord’s consent, shall relieve Tenant or any guarantor of the Lease from any liability under this Lease, including, without limitation, in connection with the Subject Space and, in the event of a Transfer of Tenant’s entire interest in this Lease, the liability of Tenant and such Transferee shall be joint and several. Landlord or its authorized representatives shall have the right at all reasonable times to audit the books, records and papers of Tenant relating to any Transfer, and shall have the right to make copies thereof. If the Transfer Premium respecting any Transfer shall be found understated, Tenant shall, within thirty (30) days after demand, pay the deficiency, and if understated by more than five percent (5%), Tenant shall pay Landlord’s costs of such audit. Notwithstanding anything to the contrary contained in this Article 14, Landlord, at its option in its sole and absolute discretion, may require, as a condition to the validity of any Transfer, that both Tenant and such Transferee enter into a separate written agreement directly with Landlord (a “Transfer Agreement”), which Transfer Agreement, among other things, shall create privity of contract between Landlord and such Transferee with respect to the provisions of this Article 14, and shall contain such terms and provisions as Landlord may reasonably require, including, without limitation, the following: (A) such Transferee’s agreement to be bound by all the obligations of Tenant under this Lease (including, but not limited to, Tenant’s obligation to pay Rent), provided that, in the event of a Transfer of less than the entire Premises, the obligations to which such Transferee shall agree to be so bound shall be prorated on a basis of the number of rentable square feet of the Subject Space in proportion to the number of square feet in the Premises; (B) such Transferee’s acknowledgment of, and agreement that such Transfer shall be subordinate and subject to, Landlord’s rights under Section 19.2.4 of this Lease; and (C) Tenant’s and such Transferee’s recognition of and agreement to be bound by all the terms and provisions of this Article 14, including, but not limited to, any such terms and provisions which Landlord, at its option, requires to be expressly set forth in such Transfer Agreement. Upon the occurrence of any default by Transferee under such Transfer, Landlord shall have the right, at its option, but not the obligation, on behalf of Tenant, to pursue any or all of the remedies available to Tenant under such Transfer or at law or in equity (all of which remedies shall be distinct, separate and cumulative).

14.6 Additional Transfers. For purposes of this Lease, the term “Transfer” shall also include (i) if Tenant is a partnership or limited liability company, the withdrawal or change, voluntary, involuntary or by operation of law, of fifty percent (50%) or more of the partners or members, or transfer of fifty percent (50%) or more of partnership or membership interests, or the dissolution of the partnership without immediate reconstitution thereof, and (ii) if Tenant is a closely held corporation (i.e., whose stock is not publicly held and not traded through an exchange or over the counter),

(A) the dissolution of Tenant or (B) the sale or other transfer of an aggregate of fifty percent (50%) or more of the voting shares of Tenant (other than to immediate family members by reason of gift or death), or (C) the sale of an aggregate of fifty percent (50%) or more of the value of the unencumbered assets of Tenant.

14.7 Occurrence of Default. Any Transfer hereunder shall be subordinate and subject to the provisions of this Lease, and if this Lease shall be terminated during the term of any Transfer, Landlord shall have the right to: (i) treat such Transfer as cancelled and repossess the Subject Space by any lawful means, or (ii) require that such Transferee attorn to and recognize Landlord as its landlord under any such Transfer. If an Event of Default by Tenant has occurred under this Lease, Landlord is hereby irrevocably authorized, as Tenant’s agent and attorney-in-fact, to direct any Transferee to make all payments under or in connection with the Transfer directly to Landlord (which Landlord shall apply towards Tenant’s obligations under this Lease). Such Transferee shall rely on any representation by Landlord that an Event of Default by Tenant has occurred hereunder, without any need for confirmation thereof by Tenant. Upon any assignment of this Lease, the assignee shall assume in writing all obligations and covenants of Tenant thereafter to be performed or observed under this Lease. No collection or acceptance of rent by Landlord from any Transferee shall be deemed a waiver of any provision of this Article 14 or the approval of any Transferee or a release of Tenant from any obligation under this Lease, whether theretofore or thereafter accruing. In no event shall Landlord’s enforcement of any provision of this Lease against any Transferee be deemed a waiver of Landlord’s right to enforce any term of this Lease against Tenant or any other person. If Tenant’s obligations hereunder have been guaranteed, Landlord’s consent to any Transfer shall not be effective unless the guarantor also consents to such Transfer.

ARTICLE 15

SURRENDER OF PREMISES; OWNERSHIP AND

REMOVAL OF TRADE FIXTURES

15.1 Surrender of Premises. No act or thing done by Landlord or any agent or employee of Landlord during the Lease Term shall be deemed to constitute an acceptance by Landlord of a surrender of the Premises unless such intent is specifically acknowledged in writing by Landlord. The delivery of keys to the Premises to Landlord or any agent or employee of Landlord shall not constitute a surrender of the Premises or effect a termination of this Lease, whether or not the keys are thereafter retained by Landlord, and notwithstanding such delivery Tenant shall be entitled to the return of such keys at any reasonable time upon request until this Lease shall have been properly terminated. The voluntary or other surrender of this Lease by Tenant, whether accepted by Landlord or not, or a mutual termination hereof, shall not work a merger, and at the option of Landlord shall operate as an assignment to Landlord of all subleases or subtenancies affecting the Premises or terminate any or all such sublessees or subtenancies.

15.2 Removal of Tenant Property by Tenant. On or before the expiration or earlier termination of this Lease, Tenant shall remove at Tenant’s expense (i) all of Tenant’s Property (defined below) and Tenant’s signage from the Premises and other portions of the Project, (ii) any Permitted Alterations, and (iii) any other Alterations Landlord, by notice to Tenant given at the time Landlord has consented to such Alteration, has required Tenant to remove, and Tenant shall repair any damage caused by all of such removal activities. “Tenant’s Property” means all equipment, trade fixtures, furnishings, all telephone, data, and other cabling and wiring (including any cabling and wiring associated with the Wi-Fi Network, if any) installed or caused to be installed by Tenant (including any cabling and wiring, installed above the ceiling of the Premises or below the floor of the Premises), inventories, goods and personal property of Tenant. Any of Tenant’s Property not so removed by Tenant as required herein shall be deemed abandoned and may be stored, removed, and disposed of by Landlord at Tenant’s expense, and Tenant waives all claims against Landlord for any damages resulting from Landlord’s retention and disposition of such property; provided, however, Tenant shall remain liable to Landlord for all costs incurred in storing and disposing of such abandoned property of Tenant. Landlord may elect to take responsibility to remove any such wiring or cabling installed above the ceiling or beneath the floors of the Premises, in which case Tenant shall pay Landlord for the actual reasonable cost incurred by Landlord therefor, within thirty (30) days after being billed for the same. Notwithstanding anything contained herein to the contrary, in the event Tenant elects, in accordance with the terms, covenants and conditions of this Lease, to remove the existing corridors located on the North or South sides of the eleventh (11^th) floor of the Building (as shown on Exhibit E attached hereto), at the expiration or earlier termination of the Lease, Landlord shall have the right (but not the obligation) to restore such corridors following Lease termination to Building standard condition and Tenant shall be obligated to reimburse

Landlord for all reasonable costs incurred in connection therewith within thirty (30) days after receipt of an invoice therefor, together with reasonable back-up documentation. In the event that Tenant exercises its Option in accordance with the terms of Section 2.2 above, then Tenant shall only be obligated to reimburse Landlord for one-third of the reasonable restoration costs incurred by Landlord pursuant to the immediately preceding sentence and, in the event that the Lease Term is extended such that Tenant occupies the Premises for at least one hundred eighty (180) consecutive months, then Tenant shall not be obligated to reimburse Landlord for any restoration costs incurred by Landlord pursuant to the immediately preceding sentence. In the event Tenant elects, in accordance with the terms, covenants and conditions of this Lease, to remove the existing corridors located on the East side of the eleventh (11^th) floor of the Building, Tenant shall have no obligation to restore such corridor on the expiration or earlier termination of the Lease. The terms of this Section 15.2 shall survive the expiration or earlier termination of the Lease. All Alterations except those which Landlord requires Tenant to remove shall remain in the Premises as the property of Landlord. If the Premises are not surrendered at the expiration of the Term or earlier termination of this Lease, and in accordance with this Article 15, Tenant shall continue to be responsible for the payment of Rent (as the same may be increased pursuant to Article 16 below) until the Premises are so surrendered in accordance with said provisions.

ARTICLE 16

HOLDING OVER

If Tenant holds over after the expiration of the Lease Term or earlier termination thereof, with or without the express or implied consent of Landlord, such tenancy shall be at the sufferance of Landlord and shall not constitute a renewal hereof or an extension for any further term, and in such case Rent for the full hold over period shall be payable in advance, as minimum damages and not as a penalty, at a monthly rate equal to (A) 150% of the Rent applicable during the last rental period of the Lease Term under this Lease during the first sixty (60) days of holdover, and (B) 200% of the Rent applicable during the last rental period of the Lease Term under this Lease thereafter. During any such holdover period, Tenant shall pay a full month’s rent for each month, or any portion thereof, that tenancy is extended beyond the Lease Expiration Date. Such holdover tenancy shall be subject to every other applicable term, covenant and agreement contained herein. For purposes of this Article 16, a holding over shall include Tenant’s remaining in the Premises after the expiration or earlier termination of the Lease Term to remove any Alterations or Non Standard Tenant Improvements located within the Premises and replace the same with Building Standard Tenant Improvements to the extent such removal and replacement is required in this Lease or the Tenant Work Letter. Nothing contained in this Article 16 shall be construed as consent by Landlord to any holding over by Tenant, and Landlord expressly reserves the right to require Tenant to surrender possession of the Premises to Landlord as provided in this Lease upon the expiration or other termination of this Lease. The provisions of this Article 16 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided 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 Claims resulting from such failure, including, without limitation, the generality of the foregoing, so long as Landlord has provided notice (oral or written) to Tenant that another tenant intends to occupy the Premises, any Claims made by any succeeding tenant founded upon such failure to surrender and any lost profits to Landlord resulting therefrom.

ARTICLE 17

ESTOPPEL CERTIFICATES

Within ten (10) days following a request in writing by Landlord, Tenant shall execute, acknowledge and deliver to Landlord an estoppel certificate, which, as submitted by Landlord, shall be in the form as may be required by any prospective mortgagee or purchaser of the Project (or any portion thereof), indicating therein any exceptions thereto that may exist at that time, and shall also contain any other information reasonably requested by Landlord or Landlord’s mortgagee or prospective mortgagee. Any such certificate may be relied upon by any prospective mortgagee or purchaser of all or any portion of the Project. Tenant shall execute and deliver whatever other instruments may be reasonably required for such purposes. In addition, no more than once in any twelve (12) month period, if requested by Landlord, Tenant shall provide to Landlord, any actual or potential purchaser, mortgagee or ground lessor or any representative of any of the foregoing, copies of Tenant’s annual financial statements (audited if available), certified as

true and correct by the president or chief financial officer of Tenant; provided that so long as the stock of Tenant is publicly traded, documents on file with the Securities and Exchange Commission and available to Landlord shall satisfy such financial reporting requirements. Failure of Tenant to timely execute, acknowledge and deliver such estoppel certificate or other instruments to Landlord shall constitute an acceptance of the Premises and an acknowledgment by Tenant that statements included in the estoppel certificate are true and correct, without exception. In addition, if Tenant fails to execute and deliver to Landlord an estoppel certificate on or prior to the expiration of five (5) days following a second request in writing from Landlord after the expiration of the ten (10) day period following Landlord’s initial notice to Tenant, then Tenant shall be liable to Landlord, and shall indemnify, defend and hold Landlord harmless from and against any Claims incidental, consequential, or otherwise, arising or accruing directly or indirectly, from any failure of Tenant to execute or deliver to Landlord any such estoppel certificate.

ARTICLE 18

SUBORDINATION

18.1 Subordination; Non-Disturbance and Attornment. This Lease shall be subject and subordinate to all present and future ground or underlying leases of the Building or Project and to the lien of any mortgage, trust deed or other encumbrances now or hereafter in force against the Building or Project or any part thereof, if any, and to all renewals, extensions, modifications, consolidations and replacements thereof, and to all advances made or hereafter to be made upon the security of such mortgages or trust deeds, unless the holders of such mortgages, trust deeds or other encumbrances, or the lessors under such ground lease or underlying leases, require in writing that this Lease be superior thereto. Tenant covenants and agrees in the event any proceedings are brought for the foreclosure of any such mortgage or deed in lieu thereof (or if any ground lease is terminated), to attorn, without any deductions or set-offs whatsoever, to the lienholder or purchaser or any successors thereto upon any such foreclosure sale or deed in lieu thereof (or to the ground lessor), if so requested to do so by such purchaser or lienholder or ground lessor, and to recognize such purchaser or lienholder or ground lessor as the lessor under this Lease, provided such lienholder or purchaser or ground lessor shall agree to accept this Lease and not disturb Tenant’s occupancy, so long as Tenant timely pays the rent and observes and performs the terms, covenants and conditions of this Lease to be observed and performed by Tenant. Landlord’s interest herein may be assigned as security at any time to any lienholder. Tenant shall, within ten (10) days of request by Landlord, execute such further instruments or assurances as Landlord may reasonably deem necessary to evidence or confirm the subordination or superiority of this Lease to any such mortgages, trust deeds, ground leases or underlying leases. Tenant waives the provisions of any current or future statute, rule or law which may give or purport to give Tenant any right or election to terminate or otherwise adversely affect this Lease and the obligations of the Tenant hereunder in the event of any foreclosure proceeding or sale.

Landlord hereby represents that, as of the date hereof, the Building and the Project are not encumbered by any mortgage, deed of trust, or ground lease. Notwithstanding anything to the contrary contained herein, as a condition precedent to Tenant’s obligation to subordinate this Lease to any future mortgage, deed of trust, ground lease or other lease, Landlord shall obtain from the holder of such future mortgage or deed of trust or the lessor under such future ground lease or other lease a non-disturbance agreement in favor of Tenant in commercially reasonable form that provides in substance that, so long as Tenant shall not then be in default in the performance of any of its obligations under this Lease beyond any applicable notice and cure period, Tenant’s possession of the Premises in accordance with this Lease shall not be disturbed by such mortgagee or lessor or any successor or purchaser at a foreclosure sale (as the case may be) which shall succeed to the rights of Landlord under this Lease.

18.2 Notice to Lienholder or Ground Lessor. Notwithstanding anything to the contrary contained in this Lease, upon receipt by Tenant of notice from any holder of a mortgage, trust deed or other encumbrance in force against the Building or the Project or any part thereof which includes the Premises or any lessor under a ground lease or underlying lease of the Building or the Project, or from Landlord, which notice sets forth the address of such lienholder or ground lessor, no notice from Tenant to Landlord shall be effective unless and until a copy of the same is given to such lienholder or ground lessor at the appropriate address therefor (as specified in the above-described notice or at such other places as may be designated from time to time in a notice to Tenant in accordance with Section 28.19 below), and the curing of any of Landlord’s defaults by such lienholder or ground lessor within a reasonable period of time after such notice from Tenant (including a reasonable period of time to obtain possession of the Building or the Project, as the case

may be, if such lienholder or ground lessor elects to do so) shall be treated as performance by Landlord. For the purposes of this Article 18, the term “mortgage” shall include a mortgage on a leasehold interest of Landlord (but not a mortgage on Tenant’s leasehold interest hereunder).

18.3 Assignment of Rents. With reference to any assignment by Landlord of Landlord’s interest in this Lease, or the Rent payable to Landlord hereunder, conditional in nature or otherwise, which assignment is made to any holder of a mortgage, trust deed or other encumbrance in force against the Building or the Project or any part thereof which includes the Premises or to any lessor under a ground lease or underlying lease of the Building or the Project, Tenant agrees that (i) the execution of any such assignment by Landlord, and the acceptance thereof by such lienholder or ground lessor, shall never be treated as an assumption by such lienholder or ground lessor of any of the obligations of Landlord under this Lease, unless such lienholder or ground lessor shall, by notice to Tenant, specifically otherwise elect; and (ii) notwithstanding delivery to Tenant of the notice required by Section 18.2, above, such lienholder or ground lessor, respectively, shall be treated as having assumed Landlord’s obligations under this Lease only upon such lienholder’s foreclosure of any such mortgage, trust deed or other encumbrance, or acceptance of a deed in lieu thereof, and taking of possession of the Building or the Project or applicable portion thereof, or such ground lessor’s termination of any such ground lease or underlying leases and assumption of Landlord’s position hereunder, as the case may be.

ARTICLE 19

DEFAULTS; REMEDIES

19.1 Events of Default. The occurrence of any of the following shall constitute an “Event of Default” of this Lease by Tenant:

19.1.1 Any failure by Tenant to pay any Rent or any other charge required to be paid under this Lease, or any part thereof, when due and such default shall continue for three (3) days after Landlord shall have given Tenant written notice of such default; or

19.1.2 Except where a specific time period is otherwise set forth for Tenant’s performance pursuant to this Section 19.1, any failure by Tenant to observe or perform any other provision, covenant or condition of this Lease to be observed or performed by Tenant where such failure continues for thirty (30) days after written notice thereof from Landlord to Tenant; provided that if the nature of such default is such that the same cannot reasonably be cured within a thirty (30) day period, Tenant shall not be deemed to be in default if it diligently commences such cure within such period and thereafter diligently proceeds to rectify and cure such default and actually completes the cure of such default within ninety (90) days from receipt of Landlord’s notice; or

19.1.3 To the extent permitted by law, a general assignment by Tenant or any guarantor of this Lease for the benefit of creditors, or the taking of any corporate action in furtherance of bankruptcy or dissolution whether or not there exists any proceeding under an insolvency or bankruptcy law, or the filing by or against Tenant or any guarantor of any proceeding under an insolvency or bankruptcy law, unless in the case of a proceeding filed against Tenant or any guarantor the same is dismissed within sixty (60) days, or the appointment of a trustee or receiver to take possession of all or substantially all of the assets of Tenant or any guarantor, unless possession is restored to Tenant or such guarantor within thirty (30) days, or any execution or other judicially authorized seizure of all or substantially all of Tenant’s assets located upon the Premises or of Tenant’s interest in this Lease, unless such seizure is discharged within thirty (30) days; or

19.1.4 Abandonment of all or a substantial portion of the Premises by Tenant while Tenant is in default of any other material term, covenant or condition of this Lease; or

19.1.5 The failure by Tenant to observe or perform according to, or to deliver the documents required within the time periods specified by, the provisions of Articles 10, 14, 17 or 18 of this Lease where such failure continues for more than three (3) business days after notice from Landlord.

The notice periods provided herein are 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.

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

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

(i) The worth at the time of any unpaid rent which has been earned at the time of such termination; plus

(ii) 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

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

(iv) 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

(v) 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 19.2 shall be deemed to be and to mean all sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or to others. As used in Paragraphs 19.2.1(i) and (ii) above, the “worth at the time of award” shall be computed by allowing interest at the rate set forth in Article 24 of this Lease, but in no case greater than the maximum amount of such interest permitted by law. As used in Paragraph 19.2.1(iii) 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 two percent (2%).

19.2.2 Landlord shall have the remedy described in California Civil Code Section 1951.4 (lessor may continue lease in effect after lessee’s breach and abandonment and recover rent as it becomes due, if lessee has the right to sublet or assign, subject only to reasonable limitations). Accordingly, if Landlord does not elect to terminate this Lease on account of any Event of Default by Tenant, 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.

19.2.3 Landlord shall at all times have the rights and remedies (which shall be cumulative with each other and cumulative and in addition to those rights and remedies available under Sections 19.2.1 and 19.2.2 above, or any law or other provision of this Lease), without prior demand or notice except as required by applicable law, to seek any declaratory, injunctive or other equitable relief, and specifically enforce this Lease, or restrain or enjoin a violation or breach of any provision hereof.

19.2.4 If Landlord elects to terminate this Lease on account of any Event of Default by Tenant, as set forth in this Article 19, then Landlord shall have the right, at Landlord’s option in its sole discretion, (i) to terminate any and all assignments, subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises, in which event Landlord shall have the right to repossess such affected portions of the Premises by any lawful means, or (ii) to succeed to Tenant’s interest in any or all such assignments, subleases, licenses, concessions or arrangements, in which event Landlord may require any assignees, sublessees, licensees or other parties thereunder to attorn to and recognize Landlord as its assignor, sublessor, licensor, concessionaire or transferor thereunder. In the event of Landlord’s election to succeed to Tenant’s interest in any such assignments, subleases, licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder.

19.3 Form of Payment After Default. Following the occurrence of any Event of Default by Tenant of any of the terms, covenants or conditions of this Lease, Landlord shall have the right to require that any or all subsequent amounts paid by Tenant to Landlord hereunder, whether to cure the default in question or otherwise, be paid in the form of cash, money order, cashier’s or certified check drawn on an institution acceptable to Landlord, or by other means approved by Landlord, notwithstanding any prior practice of accepting payments in any different form.

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

19.5 Landlord’s Default. Landlord shall not be deemed to be in default hereunder unless such default shall remain uncured for more than thirty (30) days following receipt of written notice from Tenant to Landlord specifying the nature of such default, or such longer period as reasonably may be required to correct such default (provided that Landlord has commenced such cure within such thirty (30) day period and is diligently and continuously prosecuting the same to completion). If Landlord shall fail to perform any of the terms, provisions, covenants or conditions to be performed or complied with by Landlord under Section 7.2 of this Lease with respect only to the Premises (such terms, provisions, covenants or conditions are referred to herein, collectively, as “Landlord Repair Obligations”) after expiration of all applicable notice and cure periods for Landlord’s and any mortgagee’s benefit as set forth in this Lease, then Tenant may, at Tenant’s option and risk, but without any obligation to do so, after delivery of an additional twenty (20) day prior written notice to Landlord, perform such Landlord Repair Obligations on Landlord’s behalf. If Tenant so performs any of such Landlord Repair Obligations hereunder, then Tenant will perform such Landlord Repair Obligations (i) in compliance with all applicable laws, regulations and requirements to which Landlord would be subject under this Lease (if Landlord were performing such Landlord Repair Obligations), (ii) in a good workmanlike manner using materials of a quality and grade at least equal to that in place as of the date of delivery of the Premises to Tenant, if applicable, (iii) without interfering with the rights of other tenants of the Building or Project, and (iv) in compliance with the terms and provisions of Section 8.2 hereof, as applicable. Tenant will promptly assign to Landlord any warranties or guaranties in respect of any Landlord Repair Obligations. If Tenant so performs any of such Landlord Repair Obligations hereunder, the full amount of the fair and reasonable costs and expenses incurred by Tenant shall be owing by Landlord to Tenant, and Landlord shall pay to Tenant the full undisputed amount thereof within thirty (30) days of Landlord’s receipt of Tenant’s written demand therefor together with reasonable evidence verifying the amount of such costs and expenses.

ARTICLE 20

COVENANT OF QUIET ENJOYMENT

Landlord covenants that Tenant, on paying the Rent, charges for services and other payments herein reserved and on keeping, observing and performing all the other terms, covenants, conditions, provisions and agreements herein contained on the part of Tenant to be kept, observed and performed, shall, during the Lease Term, peaceably and quietly have, hold and enjoy the Premises subject to the terms, covenants, conditions, provisions and agreements hereof without interference by any persons lawfully claiming by or through Landlord. The foregoing covenant is in lieu of any other covenant express or implied.

ARTICLE 21

SECURITY DEPOSIT

Concurrently with execution hereof, Tenant shall deposit with Landlord a security deposit (“Security Deposit”), in the amount set forth in Section 8 of the Summary, as security for the full and faithful performance of Tenant’s obligations under this Lease. Landlord may (but shall not be required to) use the Security Deposit or any portion thereof to cure any defaults on the part of Tenant or to compensate Landlord for any damage Landlord incurs as a result of Tenant’s failure to perform any of its covenants or obligations hereunder, it being understood that any use of the Security Deposit shall not constitute a bar or defense to any of Landlord’s remedies under this Lease, at law or in equity. In such event, and upon written notice from Landlord to Tenant specifying the amount of the Security Deposit so utilized by Landlord and the particular purpose for which such amount was applied, Tenant shall immediately deposit with Landlord an amount sufficient to return the Security Deposit to the amount specified in Section 8 of the Summary. Upon expiration of the Lease Term or earlier termination, the Security Deposit shall be returned to Tenant, reduced by those amounts that may be required by Landlord to remedy defaults on the part of Tenant in the payment of Rent, to repair damages to the Premises caused by Tenant and to clean the Premises. The portion of the deposit not so required shall be paid over to Tenant within sixty (60) days after expiration of the Term or earlier termination hereof. Landlord shall hold the Security Deposit for the foregoing purposes; provided, however, that Landlord shall have no obligation to segregate the Security Deposit from its general funds or to pay interest thereon. If Landlord conveys or transfers its interest in the Premises, and as a part of such conveyance or transfer, assigns its interest in this Lease and Security Deposit, or any portion thereof not previously applied, the Security Deposit shall be transferred to Landlord’s successor and the Landlord named herein shall be released and discharged from any further liability to Tenant with respect to such Security Deposit. In no event shall any mortgagee or beneficiary under a mortgage or deed of trust encumbering all or any portion of the Project, or any purchaser of all or any portion of the Project at a public or private foreclosure sale or exercise of a power of sale under such mortgage or deed of trust, have any liability or obligation whatsoever to Tenant or Tenant’s successors or assigns for the return of all or any part of the Security Deposit in the event any such mortgagee, beneficiary or purchaser becomes a mortgagee in possession or succeeds to the interest of Landlord under this Lease unless, and then only to the extent that, such mortgagee, beneficiary or purchaser has received all or any part of the Security Deposit. Tenant hereby waives (i) California Civil Code Section 1950.7 and any and all other Applicable Laws applicable to security deposits in the commercial context (“Security Deposit Laws”), and (ii) 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 herein, the security deposit may additionally be retained and applied by Landlord (a) to offset Rent which is unpaid either before or after termination of this Lease, and (b) against other damages suffered by Landlord before or after termination of this Lease.

ARTICLE 22

SIGNS

22.1 Full Floors. Subject to Landlord’s prior written approval, which approval shall not be unreasonably withheld, conditioned or delayed, and provided all signs are in keeping with the quality, design and style of the Building and Project, Tenant, if the Premises comprise an entire floor of the Building, at its sole cost and expense, may install identification signage anywhere in the Premises including in the elevator lobby of the Premises, provided that such signs must not be visible from the exterior of the Building. Alternatively, Tenant may elect to have Landlord provide such identifying signage, which signage shall be comparable to that used by Landlord for other similar floors in the Building and shall comply with Landlord’s Building standard signage program, in which event Landlord shall pay for the cost of the initial installation of such signage, and Tenant shall pay for the cost of any changes thereto.

22.2 Multi-Tenant Floors. If other tenants occupy space on the floor on which the Premises is located, Tenant’s identifying signage shall be provided by Landlord, and such signage shall be comparable to that used by Landlord for other similar floors in the Building and shall comply with Landlord’s Building standard signage program. Landlord shall pay for the cost of the initial installation of such signage, and Tenant shall pay for the cost of any changes thereto.

22.3 Prohibited Signage and Other Items. Any signs, notices, logos, pictures, names or advertisements which are installed and that have not been separately approved by Landlord may be removed without notice by Landlord at the sole expense of Tenant. Tenant may not install any signs on the exterior or roof of the Project or the Common Areas. Any signs, window coverings, or blinds (even if the same are located behind the Landlord-approved window coverings for the Building), or other items visible from the exterior of the Premises or Building, shall be subject to the prior approval of Landlord, in its sole discretion.

22.4 Building Directory. A building directory will be located in the lobby of the Building. Tenant shall have the right, at Landlord’s expense, to designate one (1) name to be displayed on such directory.

ARTICLE 23

COMPLIANCE WITH LAW

Tenant shall not do anything or suffer anything to be done in or about the Premises or the Project which will in any way conflict with any Applicable Laws. At its sole cost and expense, Tenant shall promptly comply with all such Applicable Laws which relate to (i) Tenant’s use of the Premises, (ii) the Alterations or tenant improvements in the Premises, or (iii) the Base Building, but, as to the Base Building, only to the extent such obligations are triggered by Tenant’s Alterations, the Tenant Improvements, or Tenant’s particular manner of use of the Premises. Should any standard or regulation now or hereafter be imposed on Landlord or Tenant by a state, federal or local governmental body charged with the establishment, regulation and enforcement of occupational, health or safety standards for employers, employees, landlords or tenants, then Tenant agrees, at its sole cost and expense, to comply promptly with such standards or regulations.

Without limiting the generality of the above, Tenant shall promptly comply with all requirements of the Americans with Disabilities Act and the regulations promulgated under it in effect from time to time (“ADA Requirements”) relating to the conduct of Tenant’s business. The judgment of any court of competent jurisdiction or the admission of Tenant in any judicial action, regardless of whether Landlord is a party thereto, that Tenant has violated any of the said governmental measures shall be conclusive of that fact as between Landlord and Tenant.

Tenant shall have exclusive responsibility for compliance with ADA Requirements pertaining to the interior of the Premises, including the design and construction of access thereto and egress therefrom. Landlord shall have responsibility for compliance with ADA Requirements and Title 24 standards which affect the Common Areas of the Building (including, without limitation, common restrooms and paths of travel), subject to Tenant’s obligation to pay for its share of the expense of such compliance pursuant to Article 4 of this Lease. Tenant shall comply promptly with any direction of any governmental authority having jurisdiction which imposes any duty upon Tenant or Landlord with respect to the Premises or with respect to the use or occupancy thereof. Tenant shall furnish Landlord with a copy of any such direction promptly after receipt of the same. In addition, Tenant shall comply with any reasonable plan adopted by Landlord which is designed to fulfill the requirements of any Applicable Laws, including ADA Requirements.

Should compliance by Tenant with ADA Requirements under this Article 23 require Landlord’s consent under Article 8 of this Lease, Tenant shall promptly seek such consent, provide the assurances and documents required by Article 8 and, following receipt of such consent, promptly comply with the provisions of Article 8 and ADA Requirements under this Article 23.

If Tenant fails to comply with ADA Requirements as required in this paragraph, then, after reasonable notice to Tenant, Landlord may comply or cause such compliance, in which case Tenant shall reimburse Landlord upon demand for Landlord’s reasonable costs incurred in effecting compliance.

ARTICLE 24

LATE CHARGES

If any installment of Rent or any other sum due from Tenant shall not be received when said amount is due, then Tenant shall pay to Landlord a late charge equal to five percent (5%) of the overdue amount plus any attorneys’ fees incurred by Landlord by reason of Tenant’s failure to pay Rent and/or other charges when due hereunder. The late charge shall be deemed Additional Rent and the right to require it shall be in addition to all of Landlord’s other rights and remedies hereunder or at law and shall not be construed as liquidated damages or as limiting Landlord’s remedies in any manner. In addition to the late charge described above, any Rent or other amounts owing hereunder which are not paid within ten (10) days after the date they are due shall bear interest from the date when due until paid at a rate per annum equal to the lesser of (i) the annual “Bank Prime Loan” rate cited in the Federal Reserve Statistical Release Publication G.13(415), published on the first Tuesday of each calendar month (or such other comparable index as Landlord and Tenant shall reasonably agree upon if such rate ceases to be published) plus two (2) percentage points, and (ii) the highest rate permitted by applicable law. Notwithstanding the foregoing, in the first instance each calendar year wherein Tenant is late in making a payment to Landlord of Rent or any other sum payable by Tenant hereunder, the foregoing late charge shall not be assessed until five (5) days after such Rent or other amount is past due.

ARTICLE 25

LANDLORD’S RIGHT TO CURE DEFAULT; PAYMENTS BY TENANT

25.1 Landlord’s Cure. All covenants and agreements to be kept or performed by Tenant under this Lease shall be performed by Tenant, at Tenant’s sole cost and expense, and without any reduction of Rent, except to the extent, if any, otherwise expressly provided herein. If Tenant shall fail to perform any obligation under this Lease, and such failure shall continue in excess of the time allowed under Section 19.1.2 above, unless a specific time period is otherwise stated in this Lease, Landlord may, but shall not be obligated to, make any such payment or perform any such act on Tenant’s part without waiving its rights based upon any default of Tenant and without releasing Tenant from any obligations hereunder.

25.2 Tenant’s Reimbursement. Except as may be specifically provided to the contrary in this Lease, Tenant shall pay to Landlord, upon delivery by Landlord to Tenant of statements therefor: (i) sums equal to expenditures reasonably made and obligations incurred by Landlord in connection with the remedying by Landlord of Tenant’s defaults pursuant to the provisions of Section 25.1 above; (ii) sums equal to all Claims referred to in Article 10 of this Lease; and (iii) sums equal to all expenditures made and obligations incurred by Landlord in collecting or attempting to collect the Rent or in enforcing or attempting to enforce any rights of Landlord under this Lease or pursuant to law, including, without limitation, all legal fees and other amounts so expended and interest on all such sums from the date accrued by Landlord until paid by Tenant at a rate per annum equal to the lesser of ten percent (10%) or the maximum rate permitted by law. Tenant’s obligations under this Section 25.2 shall survive the expiration or sooner termination of the Lease Term.

ARTICLE 26

ENTRY BY LANDLORD

Landlord reserves the right at all reasonable times and upon reasonable notice to Tenant (which notice, notwithstanding anything to the contrary contained within this Lease, may be oral, and which notice shall not be required in the case of an emergency) to enter the Premises to (i) inspect them; (ii) show the Premises to prospective purchasers, mortgagees or, during the last year of the Lease Term, to prospective tenants, or to current or prospective mortgagees, ground or underlying lessors or insurers; (iii) post notices of non-responsibility; or (iv) alter, improve or repair the Premises or the Building, or for structural alterations, repairs or improvements to the Building or the Building’s systems and equipment. Notwithstanding anything to the contrary contained in this Article 26, Landlord may enter the Premises at any time to (A) perform services required of Landlord, including janitorial service; (B) take possession due to any Event of Default by Tenant in the manner provided herein; and (C) perform any covenants of Tenant which Tenant fails

to perform. Landlord may make any such entries without the abatement of Rent and may take such reasonable steps as required to accomplish the stated purposes. Except to the extent caused by Landlord’s gross negligence or willful misconduct, Tenant hereby waives any claims for damages or for any injuries or inconvenience to or interference with Tenant’s business, lost profits, any loss of occupancy or quiet enjoyment of the Premises, and any other loss occasioned thereby. For each of the above purposes, Landlord shall at all times have a key with which to unlock all the doors in the Premises, excluding Tenant’s vaults, safes and special security areas designated in advance by Tenant in writing. In an emergency, Landlord shall have the right to use any means that Landlord may deem proper to open the doors in and to the Premises. Any entry into the Premises by Landlord in the manner hereinbefore described shall not be deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an actual or constructive eviction of Tenant from any portion of the Premises. No provision of this Lease shall be construed as obligating Landlord to perform any repairs, alterations or decorations except as otherwise expressly agreed to be performed by Landlord herein. In connection with Landlord’s entry into the Premises pursuant to the terms of this Article 26, Landlord shall use commercially reasonable efforts to minimize any material and adverse interference with Tenant’s business at the Premises.

ARTICLE 27

TENANT PARKING

27.1 In General. Tenant shall rent from Landlord, commencing on the Lease Commencement Date, the number of parking spaces set forth in Section 9 of the Summary, on a monthly basis throughout the Lease Term, which parking spaces shall pertain to the Project parking facility. Tenant shall pay to Landlord for such parking spaces on a monthly basis the prevailing rate charged from time to time for the Project parking facility. In addition, Tenant shall be responsible for the full amount of any taxes imposed by any governmental authority in connection with the renting of such parking spaces by Tenant or the use of the Project parking facility by Tenant. Tenant’s continued right to use the parking spaces is conditioned upon (i) Tenant abiding by all reasonable rules and regulations which are prescribed from time to time for the orderly operation and use of the Project parking facility, including any sticker or other identification system established by Landlord, (ii) Tenant’s cooperation in seeing that Tenant’s employees and visitors also comply with such rules and regulations, and (iii) no Event of Default of Tenant existing under this Lease. Tenant’s parking spaces shall be used only for parking of automobiles no larger than full size passenger automobiles, sport utility vehicles or pick-up trucks. The parking spaces rented by Tenant pursuant to this Article 27 are provided to Tenant solely for use by Tenant’s own personnel and such rights may not be transferred, assigned, subleased or otherwise alienated by Tenant without Landlord’s prior approval. Landlord specifically reserves the right to change the size, configuration, design, layout and all other aspects of the Project parking facility at any time and Tenant acknowledges and agrees that Landlord may, without incurring any liability to Tenant and without any abatement of Rent under this Lease, from time to time, temporarily close-off or restrict access to the Project parking facility for purposes of permitting or facilitating any such construction, alteration or improvements. Landlord may delegate its responsibilities hereunder relating to the Project parking facility to a parking operator in which case such parking operator shall have all the rights of control attributed hereby to the Landlord. Tenant may validate visitor parking by such method or methods as the Landlord may establish, at the validation rate from time to time generally applicable to visitor parking.

27.2 Parking Procedures. Landlord shall have no obligation to monitor the use of the Project parking facility, nor shall Landlord be responsible for any loss or damage to any vehicle or other property or for any injury to any person. Tenant shall comply with all reasonable rules and regulations which may be adopted by Landlord from time to time with respect to parking and/or the Project parking facility. Tenant shall not at any time use more parking spaces than the number so allocated (if any) to Tenant or park its vehicles or the vehicles of others in any portion of the Project not designated by Landlord for Tenant’s parking. All trucks (other than pick-up trucks) and delivery vehicles shall be (i) parked at the loading dock of the Building, (ii) loaded and unloaded in a manner which does not unreasonably interfere with the businesses of other occupants of the Building, and (iii) permitted to remain on the Project only so long as is reasonably necessary to complete loading and unloading. In the event Landlord elects in its sole and absolute discretion, or is required by any law, to limit or control parking in the Building, whether by validation of parking tickets or any other method of assessment, Tenant agrees to participate in such validation or assessment program under such reasonable rules and regulations as are, from time to time, established by Landlord.

ARTICLE 28

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

28.5 Transfer of Landlord’s Interest. Tenant acknowledges that Landlord has the right to transfer all or any portion of its interest in the Project or Building and in this Lease, and Tenant agrees that in the event of any such transfer, Landlord shall automatically be released from all liability under this Lease and Tenant agrees to look solely to such transferee for the performance of Landlord’s obligations hereunder after the date of transfer and such transferee shall be deemed to have fully assumed and be liable for all obligations of this Lease to be performed by Landlord, including the return of any Security Deposit, and Tenant shall attorn to such transferee. Tenant further acknowledges that Landlord may assign its interest in this Lease to a mortgage lender as additional security and agrees that such an assignment shall not release Tenant from its obligations hereunder and that Tenant shall continue to look solely to Landlord for the performance of its obligations hereunder.

Time is of the essence with respect to the performance of every provision of this Lease in which time of performance is a factor, including, without limitation, the giving of any notice required to be given under this Lease or by law, the time periods for giving notice and the taking of any action with respect to such notice.

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

28.12 No Warranty. In executing and delivering this Lease, Tenant has not relied on any representations, including, but not limited to, any representation as to the amount of any item comprising Additional Rent or the amount of the Additional Rent in the aggregate or that Landlord is furnishing the same services to other tenants, at all, on the same level or on the same basis, or any warranty or any statement of Landlord which is not set forth herein or in one or more of the exhibits attached hereto.

28.13 Landlord Exculpation. The liability of Landlord or the Landlord Parties to Tenant for any default by Landlord under this Lease or arising in connection herewith or with Landlord’s operation, management, leasing, repair, renovation, alteration or any other matter relating to the Project or the Premises shall be limited solely and exclusively to the lesser of (a) the interest of Landlord in the Building or (b) the equity interest Landlord would have in the Building if the Building were encumbered by third-party debt in an amount equal to eighty percent (80%) of the value of the Building (as such value is determined by Landlord). No natural person who is a principal, member, shareholder, employee, director, officer, investor, or partner of Landlord or of any of the Landlord Parties shall have any personal liability therefor, and Tenant hereby expressly waives and releases such personal liability on behalf of itself and all persons claiming by, through or under Tenant. The limitations of liability contained in this Section 28.13 shall inure to the benefit of Landlord’s and the Landlord Parties’ present and future partners, beneficiaries, officers, directors, trustees, shareholders, agents and employees, and their respective partners, heirs, successors and assigns. Under no circumstances shall any present or future partner of Landlord (if Landlord is a partnership), or trustee or beneficiary (if Landlord or any partner of Landlord is a trust), have any liability for the performance of Landlord’s obligations under this Lease. Notwithstanding any contrary provision herein, neither Landlord nor the Landlord Parties shall be liable under any circumstances for injury or damage to, or interference with, Tenant’s business, including but not limited to, loss of profits, loss of rents or other revenues, loss of business opportunity, loss of goodwill or loss of use, in each case, however occurring.

28.14 Entire Agreement. It is understood and acknowledged that there are no oral agreements between the parties hereto affecting this Lease and this Lease (together with all Exhibits and Addenda hereto) constitutes the parties’ entire agreement with respect to the leasing of the Premises and supersedes and cancels any and all previous negotiations, arrangements, brochures, agreements and understandings, if any, between the parties hereto or displayed by Landlord to Tenant with respect to the subject matter thereof, and none thereof shall be used to interpret or construe this Lease. None of the terms, covenants, conditions or provisions of this Lease can be modified, deleted or added to except in writing signed by the parties hereto.

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

28.16 Force Majeure. Except as otherwise expressly provided herein, any prevention, delay or stoppage due to strikes, lockouts, labor disputes, acts of God, inability to obtain services, labor, or materials or reasonable substitutes therefor, governmental actions, civil commotions, fire or other casualty, and other causes beyond the reasonable control of the party obligated to perform (collectively, a “Force Majeure”) shall excuse the performance of such party for a period equal to the length of any such prevention, delay or stoppage and, therefore, if this Lease specifies a time period for performance of an obligation of either party, except as otherwise expressly provided herein, that time period shall be

extended by the period of any delay in such party’s performance caused by an event of Force Majeure; provided however, that notwithstanding the foregoing, the obligations imposed with regard to Rent and other charges to be paid by Tenant pursuant to this Lease, Tenant’s obligations pursuant to Article 5, Article 17, Article 18 and Article 23, and the time periods specified in Article 19 and in any provision of this Lease relating to Tenant’s exercise of an option or a right hereunder, shall not be subject to extension due to an event of Force Majeure.

28.17 [Intentionally Deleted].

28.18 Waiver of Redemption by Tenant. Tenant hereby waives, for Tenant and for all those claiming under Tenant, any and all rights now or hereafter existing to redeem by order or judgment of any court or by any legal process or writ, Tenant’s right of occupancy of the Premises after any termination of this Lease.

28.19 Notices. All notices, demands, statements, designations, approvals or other communications (collectively, “Notices”) given or required to be given by either party to the other hereunder or by law shall be in writing, shall be (A) sent by United States certified or registered mail, postage prepaid, return receipt requested (“Mail”), (B) transmitted by facsimile, if such facsimile is promptly followed by a Notice sent by Mail, (C) delivered by a nationally recognized overnight courier, or (D) delivered personally. Any Notice shall be sent, transmitted, or delivered, as the case may be, to Tenant at the appropriate address set forth in Section 10 of the Summary, or to such other place as Tenant may from time to time designate in a Notice to Landlord, or to Landlord at the appropriate address set forth in Section 11 of the Summary, or to such other place as Landlord may from time to time designate in a Notice to Tenant. Any Notice will be deemed given (i) three (3) days after the date it is posted if sent by Mail, (ii) the date the facsimile is transmitted, (iii) the date the overnight courier delivery is made or such delivery is refused, or (iv) the date personal delivery is made or such delivery is refused. If Tenant is notified of the identity and address of Landlord’s mortgagee or ground or underlying lessor, Tenant shall give to such mortgagee or ground or underlying lessor written notice of any default by Landlord under the terms of this Lease by registered or certified mail, and such mortgagee or ground or underlying lessor shall be given a reasonable period of time to cure such default (but in no event less than sixty (60) days following receipt of such notice) prior to Tenant’s exercising any remedy available to Tenant.

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

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

28.22 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. Without limiting the generality of the foregoing, if Landlord utilizes the services of an attorney for the purpose of collecting any Rent due and unpaid by Tenant or in connection with any other breach of this Lease by Tenant, Tenant agrees to pay Landlord actual attorneys’ fees for such services, regardless of the fact that no legal action may be commenced or filed by Landlord.

28.23 Governing Law; Waiver of Trial by Jury. This Lease shall be construed and enforced in accordance with the laws of the State of California. IN ANY ACTION OR PROCEEDING ARISING HEREFROM, LANDLORD AND TENANT HEREBY CONSENT TO (I) THE JURISDICTION OF ANY COMPETENT COURT WITHIN THE STATE OF CALIFORNIA, (II) SERVICE OF PROCESS BY ANY MEANS AUTHORIZED BY CALIFORNIA LAW, AND (III) IN THE INTEREST OF SAVING TIME AND EXPENSE, TRIAL WITHOUT A JURY IN ANY ACTION,

IN THE EVENT LANDLORD COMMENCES ANY SUMMARY PROCEEDINGS OR ACTION FOR NONPAYMENT OF BASE RENT OR ADDITIONAL RENT, TENANT SHALL NOT INTERPOSE ANY COUNTERCLAIM OF ANY NATURE OR DESCRIPTION (UNLESS SUCH COUNTERCLAIM SHALL BE MANDATORY) IN ANY SUCH PROCEEDING OR ACTION, BUT SHALL BE RELEGATED TO AN INDEPENDENT ACTION AT LAW.

28.24 Submission of Lease. Submission of this instrument for examination or signature by Tenant does not constitute a reservation of, option for or option to lease, and it is not effective as a lease or otherwise until execution and delivery by both Landlord and Tenant.

28.25 Brokers. Landlord and Tenant hereby warrant to each other that they have had no dealings with any real estate broker or agent in connection with the negotiation of this Lease, excepting only the real estate brokers or agents specified in Section 12 of the Summary (the “Brokers”), and that they know of no other real estate broker or agent who is entitled to a commission in connection with this Lease. Each party agrees to indemnify and defend the other party against and hold the other party harmless from any and all Claims with respect to any leasing commission or equivalent compensation alleged to be owing on account of any dealings with any real estate broker or agent, other than the Brokers, occurring by, through, or under the indemnifying party.

28.26 Independent Covenants. This Lease shall be construed as though the covenants herein between Landlord and Tenant are independent and not dependent and Tenant hereby expressly waives the benefit of any statute to the contrary and agrees that, except as expressly set forth in Section 19.5, if Landlord fails to perform its obligations set forth herein, Tenant shall not be entitled to make any repairs or perform any acts hereunder at Landlord’s expense or to any setoff of the Rent or other amounts owing hereunder against Landlord.

28.27 Project or Building Name and Signage. Landlord shall have the right at any time to change the name of the Project or Building and to install, affix and maintain any and all signs on the exterior and on the interior of the Project or Building as Landlord may, in Landlord’s sole discretion, desire.

28.28 Confidentiality. Tenant acknowledges that the financial terms and conditions of this Lease and any related documents are confidential information. Tenant shall keep such confidential information strictly confidential and shall not disclose such confidential information to any person or entity other than Tenant’s employees, directors, financial, legal, and space planning consultants, potential investors, and other Tenant advisors reasonably in need of such information, or as otherwise required by law (including but not limited to disclosure, if any, required under securities laws to the extent applicable to Tenant).

28.29 Transportation Management. Tenant shall fully comply with all present or future programs intended to manage parking, transportation or traffic in and around the Building, and in connection therewith, Tenant shall take responsible action for the transportation planning and management of all employees located at the Premises by working directly with Landlord, any governmental transportation management organization or any other transportation-related committees or entities.

28.30 Building Renovations. It is specifically understood and agreed that, except as specifically set forth herein, Landlord has made no representation or warranty to Tenant and has no obligation and has made no promises to alter, remodel, improve, renovate, repair or decorate the Premises, Building, or any part thereof and that no representations respecting the condition of the Premises or the Building have been made by Landlord to Tenant except as specifically set forth herein or in the Tenant Work Letter. However, Tenant hereby acknowledges that Landlord may during the Lease Term renovate, improve, alter, or modify (collectively, the “Renovations”) the Project, the Building

and/or the Premises including without limitation the parking structure, common areas, systems and equipment, roof, and structural portions of the same, which Renovations may include, without limitation, (i) installing sprinklers in the Building common areas and tenant spaces, (ii) modifying the common areas and tenant spaces to comply with Applicable Laws, including regulations relating to the physically disabled, seismic conditions, and building safety and security, and (iii) installing new floor covering, lighting, and wall coverings in the Building common areas, and in connection with any Renovations, Landlord may, among other things, erect scaffolding or other necessary structures in the Building, limit or eliminate access to portions of the Project, including portions of the common areas, or perform work in the Building, which work may create noise, dust or leave debris in the Building. Tenant hereby agrees that such Renovations and Landlord’s actions in connection with such Renovations shall in no way constitute a constructive eviction of Tenant nor entitle Tenant to any abatement of Rent. Notwithstanding the foregoing, Landlord shall use commercially reasonable efforts to minimize any interference with Tenant’s use of or access to the Premises in connection with any Renovations undertaken by Landlord. Landlord shall have no responsibility for, and shall not for any reason be liable to Tenant for, any direct or indirect injury to or interference with Tenant’s business arising from the Renovations, nor shall Tenant be entitled to any compensation or damages from Landlord for loss of the use of the whole or any part of the Premises or of Tenant’s personal property or improvements resulting from the Renovations or Landlord’s actions in connection with such Renovations, or for any inconvenience or annoyance occasioned by such Renovations or Landlord’s actions.

28.31 No Violation. Tenant hereby warrants and represents that neither its execution of nor performance under this Lease shall cause Tenant to be in violation of any agreement, instrument, contract, law, rule or regulation by which Tenant is bound, and Tenant shall protect, defend, indemnify and hold Landlord harmless against any Claims arising from Tenant’s breach of this warranty and representation.

28.32 Communications and Computer Lines. Tenant shall, in accordance with the terms and conditions hereof, have the right to install, maintain, replace, remove or use any electronic, fiber, phone and data cabling and communications or computer wires (collectively, the “Lines”) at the Project in or serving the Premises, provided that (i) Tenant shall obtain Landlord’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed), use an experienced and qualified contractor approved in writing by Landlord, and comply with all of the other provisions of Article 7 and Article 8 of this Lease, (ii) an acceptable number of spare Lines and space for additional Lines shall be maintained for existing and future occupants of the Project, as reasonably determined by Landlord, (iii) the Lines therefor (including riser cables) shall be appropriately insulated to prevent excessive electromagnetic fields or radiation, and shall be surrounded by a protective conduit reasonably acceptable to Landlord, (iv) any new or existing Lines servicing the Premises shall comply with all Applicable Laws, (v) Tenant shall prior to the expiration of this Lease, at Tenant’s expense and in compliance with the National Electric Code and other Applicable Laws, remove all Lines; provided, however, Tenant shall not remove such Lines if Tenant receives a written notice from Landlord at least fifteen (15) days prior to the expiration of the Lease authorizing such Lines to remain in place, in which event the Lines shall be surrendered with the Premises upon the expiration or earlier termination of this Lease, and (vi) Tenant shall pay all costs in connection therewith. Landlord reserves the right to require that Tenant remove any Lines located in or serving the Premises which are installed in violation of these provisions, or which are at any time in violation of any Applicable Laws or represent a dangerous or potentially dangerous condition. Landlord further reserves the right to require that Tenant remove any and all lines located in or serving the Premises upon the expiration or earlier termination of this Lease. In the event that Tenant desires access to the Building risers in connection with the exercise of its rights pursuant to this paragraph, then Tenant shall be required to utilize the services of Landlord’s designated Building riser management company.

28.33 Office and Communications Services.

28.33.1 The Provider. Landlord has advised Tenant that certain office and communications services may be offered to tenants of the Building by a concessionaire under contract to Landlord (“Provider”).

suitability thereof; (ii) the Provider is not acting as the agent or representative of Landlord in the provision of such services, and Landlord shall have no liability or responsibility for any failure or inadequacy of such services, or any equipment or facilities used in the furnishing thereof, or any act or omission of Provider, or its agents, employees, representatives, officers or contractors; (iii) Landlord shall have no responsibility or liability for the installation, alteration, repair, maintenance, furnishing, operation, adjustment or removal of any such services, equipment or facilities; and (iv) any contract or other agreement between Tenant and Provider shall be independent of this Lease, the obligations of Tenant hereunder, and the rights of Landlord hereunder, and, without limiting the foregoing, no default or failure of Provider with respect to any such services, equipment or facilities, or under any contract or agreement relating thereto, shall have any effect on this Lease or give to Tenant any offset or defense to the full and timely performance of its obligations hereunder, or entitle Tenant to any abatement of rent or additional rent or any other payment required to be made by Tenant hereunder, or constitute any accrual or constructive eviction of Tenant, or otherwise give rise to any other claim of any nature against Landlord.

The term “Embargoed Person” means any person, entity or government subject to trade restrictions under U.S. law, including but not limited to, the International Emergency Economic Powers Act, 50 U.S.C. §1701 et seq., The Trading with the Enemy Act, 50 U.S.C. App. 1 et seq., and any Executive Orders or regulations promulgated thereunder with the result that the investment in Tenant is prohibited by law or Tenant is in violation of law.

28.35.2 Tenant covenants and agrees (i) to comply with all requirements of law relating to money laundering, anti-terrorism, trade embargos and economic sanctions, now or hereafter in effect, (ii) to immediately notify Landlord in writing if any of the representations, warranties or covenants set forth in this paragraph or the preceding paragraph are no longer true or have been breached or if Tenant has a reasonable basis to believe that they may no longer be true or have been breached, (iii) not to use funds from any “Prohibited Person” (as such term is defined in the September 24, 2001 Executive Order Blocking Property and Prohibiting Transactions With Persons Who Commit, Threaten to Commit, or Support Terrorism) to make any payment due to Landlord under the Lease and (iv) at the request of Landlord, to provide such information as may be requested by Landlord to determine Tenant’s compliance with the terms hereof.

Except for the Tenant Improvement Allowance set forth below and Landlord’s obligations pursuant to Article 23 of the Lease, Landlord shall not be obligated to make or pay for any alterations or improvements to the Premises, the Building or the Project.

SECTION 2

TENANT IMPROVEMENTS

2.1 Tenant Improvement Allowance. Tenant shall be entitled to a one-time tenant improvement allowance (the “Tenant Improvement Allowance”) in the amount of up to, but not exceeding $60.00 per rentable square foot of the Premises (i.e., up to $933,600 based on 15,560 rentable square feet of the Premises), for the costs relating to the initial design and construction of Tenant’s improvements which are permanently affixed to the Premises (the “Tenant Improvements”), including, without limitation, space planning and design, construction fees, and architectural and consultant fees; provided, however, that Landlord shall have no obligation to disburse all or any portion of the Tenant Improvement Allowance to Tenant unless Tenant makes a request for disbursement pursuant to the terms and conditions of Section 2.2 below prior to that date which is six (6) months after the Lease Commencement Date. In no event shall Landlord be obligated to make disbursements pursuant to this Tenant Work Letter in a total amount which exceeds the Tenant Improvement Allowance. Tenant shall not be entitled to receive any cash payment or credit against Rent or otherwise for any unused portion of the Tenant Improvement Allowance which is not used to pay for the Tenant Improvement Allowance Items (as such term is defined below).

2.2 Disbursement of the Tenant Improvement Allowance.

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

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

2.2.1.5 the cost of any changes to the Construction Drawings or Tenant Improvements required by applicable laws;

2.2.1.6 sales and use taxes and Title 24 fees;

Tenant’s request for payment shall be deemed Tenant’s acceptance and approval of the work furnished and/or the materials supplied as set forth in Tenant’s payment request. Within thirty (30) days of Landlord’s receipt of a completed disbursement request submission, Landlord shall deliver a check to Tenant made jointly payable to Contractor and Tenant in payment of the lesser of (A) the amounts so requested by Tenant, as set forth in this Section 2.2.2.1, above, less a ten percent (10%) retention (the aggregate amount of such retentions to be known as the “Final Retention”) and (B) the balance of any remaining available portion of the Tenant Improvement Allowance (not including the Final Retention), provided that Landlord does not dispute any request for payment based on non-compliance of any work with the “Approved Working Drawings”, as that term is defined in Section 3.4 below, or due to any substandard work. Landlord’s payment of such amounts shall not be deemed Landlord’s approval or acceptance of the work furnished or materials supplied as set forth in Tenant’s payment request.

2.3 Standard Tenant Improvement Package. Landlord has established specifications (the “Building Standard Tenant Improvements”) for the Building standard components to be used in the construction of the Tenant Improvements in the Premises, a copy of which has been delivered to Tenant. The quality of Tenant Improvements shall be equal to or of greater quality than the quality of the Building Standard Tenant Improvements, provided that Landlord may, at Landlord’s option, require the Tenant Improvements to comply with certain Building Standard Tenant Improvements. Landlord may make changes to the Specifications from time to time.

2.4 Removal of Non Building Standard Tenant Improvements. “Non Standard Tenant Improvements” shall mean (a) any part of the Tenant Improvements which do not constitute Building Standard Tenant Improvements, including, but not limited to, plumbing and millwork; (b) any changes in or additions to the Tenant Improvements made at the request of Tenant or due to any other act or omission on the part of Tenant; and (c) a configuration of the Tenant Improvements which is not usual and customary for normal occupancy. If so directed by Landlord prior to the end of the Term of this Lease, Tenant shall pay Landlord the cost to remove from the Premises any Non Standard Tenant Improvements designated by Landlord, and shall replace such designated Non Standard Tenant Improvements to be removed with Building Standard Tenant Improvements. Notwithstanding the foregoing, in the event that Tenant’s request for approval any Tenant Improvement shall request a designation by Landlord of any removal obligation in accordance with the terms hereof, then Landlord shall indicate any such removal obligation at the time of Landlord’s consent. If Tenant makes such a request and Landlord shall not indicate in its approval that the applicable Tenant Improvement will be required to be removed by Tenant, then the applicable Tenant Improvement will not be required to be removed.

SECTION 3

3.1 Selection of Architect/Construction Drawings. Tenant shall retain the architect/space planner (the “Architect”) approved by Landlord, which approval shall not be unreasonably withheld, to prepare the Construction Drawings. Landlord hereby approves ▇▇▇▇▇▇▇▇▇-▇▇▇▇▇▇▇ Architects (Boston) and Hooks ASD (SF), collectively, as the Architect. Tenant shall retain the engineering consultants reasonably designated by Landlord (the “Engineers”) to prepare all plans and engineering working drawings relating to the structural, mechanical, electrical, plumbing, HVAC,

EXHIBIT B

life safety, and sprinkler work in the Premises. The plans and drawings to be prepared by Architect and the Engineers hereunder shall be known collectively as the “Construction Drawings”. All Construction Drawings shall comply with the drawing format and specifications reasonably determined by Landlord, and shall be subject to Landlord’s approval, which shall not be unreasonably withheld, conditioned or delayed. Tenant and Architect shall verify, in the field, the dimensions and conditions as shown on the relevant portions of the base building plans, and Tenant and Architect shall be solely responsible for the same, and Landlord shall have no responsibility in connection therewith. Landlord’s review of the Construction Drawings as set forth in this Section 3, shall be for its sole purpose and shall not imply Landlord’s review of the same, or obligate Landlord to review the same, for quality, design, Code compliance or other like matters. Accordingly, notwithstanding that any Construction Drawings are reviewed by Landlord or its space planner, architect, engineers and consultants, and notwithstanding any advice or assistance which may be rendered to Tenant by Landlord or Landlord’s space planner, architect, engineers, and consultants, Landlord shall have no liability whatsoever in connection therewith and shall not be responsible for any omissions or errors contained in the Construction Drawings.

3.2 Final Space Plan. Tenant shall supply Landlord with four (4) copies signed by Tenant of its final space plan for the Premises before any architectural working drawings or engineering drawings have been commenced. The final space plan (the “Final Space Plan”) shall include a layout and designation of all offices, rooms and other partitioning, their intended use, and equipment to be contained therein. Landlord may request clarification or more specific drawings for special use items not included in the Final Space Plan. Landlord shall advise Tenant within five (5) business days after Landlord’s receipt of the Final Space Plan for the Premises if the same is unsatisfactory or incomplete in any respect. If Tenant is so advised, Tenant shall promptly (i) cause the Final Space Plan to be revised to correct any deficiencies or other matters Landlord may reasonably require, and (ii) deliver such revised Final Space Plan to Landlord.

3.3 Final Working Drawings. After the Final Space Plan has been approved by Landlord and Tenant, Tenant shall promptly cause the Architect and the Engineers to complete the architectural and engineering drawings for the Premises, and cause the Architect to compile a fully coordinated set of architectural, structural, mechanical, electrical and plumbing working drawings in a form which is complete to allow subcontractors to bid on the work and to obtain all applicable permits for the Tenant Improvements (collectively, the “Final Working Drawings”), and shall submit the same to Landlord for Landlord’s approval. Tenant shall supply Landlord with four (4) copies signed by Tenant of such Final Working Drawings. Landlord shall advise Tenant within five (5) business days after Landlord’s receipt of the Final Working Drawings for the Premises if the same is unsatisfactory or incomplete in any respect. If Tenant is so advised, Tenant shall promptly (i) revise the Final Working Drawings in accordance with such review and any disapproval of Landlord in connection therewith, and (ii) deliver such revised Final Working Drawings to Landlord.

3.4 Approved Working Drawings. The Final Working Drawings shall be approved by Landlord (the “Approved Working Drawings”) prior to the commencement of construction of the Premises by Tenant. After approval by Landlord of the Final Working Drawings, Tenant shall promptly submit the same to the appropriate governmental authorities for all applicable building permits. Tenant hereby agrees that neither Landlord nor Landlord’s consultants shall be responsible for obtaining any building permit or certificate of occupancy for the Premises and that obtaining the same shall be Tenant’s responsibility; provided, however, that Landlord shall cooperate with Tenant in executing permit applications and performing other ministerial acts reasonably necessary to enable Tenant to obtain any such permit or certificate of occupancy. No changes, modifications or alterations in the Approved Working Drawings may be made without the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed.

ADDENDUM 1

RIGHT OF FIRST OFFER

This Addendum 1 (“Addendum 1”) is incorporated as a part of that certain Office Lease dated November 24, 2010 (the “Lease”), by and between ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇, a Delaware limited liability company (“Landlord”), and ▇▇▇▇▇▇▇▇▇ Research, Inc., a Delaware corporation (“Tenant”), for the Premises located at ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇ (the “Premises”).

2. Procedure for Acceptance. Upon any portion of the ROFO Space becoming available for lease by Tenant, Landlord shall give Tenant written notice (the “ROFO Notice”) that such ROFO Space will or has become available for lease by Tenant. Landlord shall endeavor to give Tenant a ROFO Notice (a) nine (9) months prior to the anticipated date of availability with respect to the Suite 1000 ROFO Space, and (b) six (6) months prior to the anticipated date of availability with respect to the Suite 1050 ROFO Space.

Except to the extent expressly provided herein to the contrary, Tenant must elect to exercise its ROFO provided herein, if at all, with respect to all of the space offered by Landlord to Tenant in Landlord’s ROFO Notice at any particular time, and Tenant may not elect to lease only a portion thereof.

3. Lease of ROFO Space. If Tenant timely exercises its ROFO as set forth herein, Tenant shall provide Landlord a non-refundable deposit, equivalent to the last one (1) month’s Base Rent and Operating Expenses for the ROFO Space identified in the ROFO Notice and the parties shall have ten (10) business days after Landlord receives Tenant’s Election Notice and deposit from Tenant in which to execute an amendment to the Lease adding such ROFO Space to the Premises on all of the terms and conditions as applicable to the original Premises; provided, that (a) the Base Rent for the ROFO Space shall be at the Fair Market Rental Rate as of the commencement of Tenant’s lease of the ROFO Space, determined in accordance with Section 2.2.3 of the Lease and (b) Landlord shall deliver to Tenant possession of the ROFO Space in its then existing condition and state of repair, “AS IS”, without any obligation of Landlord to remodel, improve or alter the ROFO Space, to perform any other construction or work of improvement upon the ROFO Space, but Landlord shall provide Tenant with an improvement allowance in an amount equal to One Dollar ($1.00) per rentable square foot of ROFO Space per month of the Term applicable to such ROFO Spaces that Tenant will be obligated to pay rent, which allowance shall be reduced by One Dollar ($1.00) for each month (or portion thereof) between the Lease Commencement Date and the date of Tenant’s Election Notice. Tenant acknowledges that no representations or warranties of any kind, express or implied, respecting the condition of the ROFO Space, Building, or Project have been made by Landlord or any agent of Landlord to Tenant. Tenant further acknowledges that neither Landlord nor any of Landlord’s agents, representatives or employees has made any representations as to the suitability or fitness of the ROFO

ADDENDUM 1

Space for the conduct of Tenant’s business, or for any other purpose. Any exception to the foregoing provisions must be made by express written agreement signed by both parties. Upon full execution of an amendment for the subject ROFO Space, the non-refundable deposit shall be credited toward the Base Rent for such ROFO Space, as agreed between the parties.

4. Limitations on, and Conditions to, ROFO. Notwithstanding anything in the foregoing to the contrary, at Landlord’s option, and in addition to all of Landlord’s remedies under the Lease, at law or in equity, the ROFO hereinabove granted to Tenant shall not be deemed to be properly exercised if any of the following individual events occur or any combination thereof occur: (a) an Event of Default has occurred at any time during the Lease Term; and/or (b) on the scheduled commencement date for Tenant’s lease of the ROFO Space identified in Landlord’s ROFO Notice, an Event of Default exists under the Lease; and/or (c) Tenant has assigned its rights and obligations under the Lease (except in connection with a Permitted Transfer) or Tenant has subleased more than twenty five percent (25%) of the rentable area of the Premises (except in connection with a Permitted Transfer); and/or (d) Tenant’s financial condition at the time Tenant’s Election Notice is delivered to Landlord is inadequate, in Landlord’s reasonable judgment, to satisfy Tenant’s obligations under this Lease; and/or (e) Tenant has failed to exercise properly this ROFO in a timely manner in strict accordance with the provisions of this Addendum 1; and/or (f) Tenant no longer has possession of all or any part of the Premises under the Lease (other than in connection with any Permitted Transfer or a sublease of less than twenty-five percent (25%) of the rentable area of the Premises), or if the Lease has been terminated earlier, pursuant to the terms and provisions of the Lease. Tenant’s ROFO to lease the ROFO Space is personal to the original Tenant executing the Lease (and any transferee pursuant to a Permitted Transfer), and may not be assigned or exercised, voluntarily or involuntarily, by or to, any person or entity other than the original Tenant, and shall only be available to and exercisable by the Tenant when the original Tenant is in actual and physical possession of the entire Premises.

ROOFTOP SPACE ADDENDUM

THIS ROOFTOP SPACE ADDENDUM (“Rooftop Space Addendum”) is made and entered into by and between 150 SPEAR STREET, LLC, a Delaware limited liability company (“Landlord”) and ▇▇▇▇▇▇▇▇▇ RESEARCH, INC., a Delaware corporation (“Tenant”), and is dated as of the date of the Office Lease (“Lease”) by and between Landlord and Tenant to which this Rooftop Space Addendum is attached. The agreements set forth in this Rooftop Space Addendum shall have the same force and effect as if set forth in the Lease. To the extent the terms of this Rooftop Space Addendum are inconsistent with the terms of the Lease, the terms of this Rooftop Space Addendum shall control. All capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Lease.

1. Right to Install Rooftop Equipment. During the Lease Term, and, subject to Tenant’s compliance with all Applicable Laws and covenants, conditions and restrictions, and Landlord’s prior review and approval of plans and specifications for all such installation, Tenant and Tenant’s contractors (which shall first be reasonably approved by Landlord) shall have the right to access, install, replace, remove, operate and maintain, subject to the terms of Article 8 of the Lease and this Rooftop Space Addendum, a microwave dish not exceeding two (2) feet in diameter (the “Antenna”) on the rooftop of the Building at the location more specifically shown on the diagram attached hereto as Schedule 1 to Addendum 2 (or if no location is shown on Schedule 1 to Addendum 2, at a location reasonably determined by Landlord), including the cabling and connecting equipment (collectively, the “Connecting Equipment”). The Antenna and the Connecting Equipment are collectively referred to as the “Rooftop Equipment”.

2. Fee. In consideration for Tenant’s right to install and operate the Rooftop Equipment as set forth in this Rooftop Space Addendum, Tenant shall pay to Landlord, from and after the date the Rooftop Equipment is installed, a monthly amount payable in advance on the first (1^st) day of each month, equal to the sum of $500.00. Such amount for any partial month shall be prorated based on the number of days in such partial month. Notwithstanding the foregoing, no fee under this Section 2 shall be payable by Tenant with respect to an Antenna solely for receiving DirectTV® or similar satellite television service. In lieu of Tenant’s right to install the Rooftop Equipment as provided herein, Tenant may elect to tie-in to service provided by Landlord’s existing microwave and/or satellite dish. In such event, Tenant’s tie-in to, and use of, Landlord’s existing service shall be subject to all of the terms, covenants and conditions of the Lease and Tenant shall pay to Landlord, together with payment of Base Rent, a fee of $100.00 per month for such service.

3. Conditioned Upon Lease. This Rooftop Space Addendum is contingent upon the Lease being in effect and compliance by Tenant with all of the terms and provisions hereof. If the Lease terminates or expires for any reason, Tenant’s rights under this Rooftop Space Addendum shall also terminate concurrently therewith unless otherwise agreed in writing by Landlord in its sole and absolute discretion.

4. No Assignment. Notwithstanding anything to the contrary set forth in Article 14 of the Lease Tenant’s rights under this Rooftop Space Addendum may not be assigned, transferred to or used by any other person or entity except in connection with a Permitted Transfer.

5. Installation. Tenant’s installation and operation of the Rooftop Equipment shall be governed by the following terms and conditions:

a. Installation shall be conducted by licensed contractors approved by Landlord. No roof penetrations shall permitted.

ADDENDUM 2

b. All plans and specifications for the Rooftop Equipment shall be subject to Landlord’s prior review and approval and the prior review and approval of all other tenants or occupants of the Building maintaining or operating rooftop equipment and related equipment at the Building. Upon Landlord’s request, Tenant shall prepare and submit a detailed set of plans and specifications for the proposed Rooftop Equipment, methods of installation and proposed locations thereof to all tenants and occupants having a right to review Tenant’s proposed Rooftop Equipment.

c. Tenant, at Tenant’s sole cost and expense, shall be responsible for any modifications to the rooftop, risers, utility areas or other facilities or portions of the Building which may be necessary to accommodate the Rooftop Equipment.

d. It is expressly understood that Landlord retains the right to use the roof of the Building for any purpose whatsoever (including granting rights to third parties to utilize any portion of the roof not utilized by Tenant).

e. For the purposes of determining Tenant’s obligations with respect to its use of the roof of the Building herein provided, all of the provisions of the Lease relating to compliance with requirements as to insurance, indemnity, and compliance with Applicable Laws shall apply to the installation, use and maintenance of the Rooftop Equipment. Landlord shall not have any obligations with respect to the Rooftop Equipment. Landlord makes no representation that the Rooftop Equipment will function properly and Tenant agrees that Landlord shall not be liable to Tenant therefor.

f. Tenant shall (i) be solely responsible for any damage caused as a result of the Rooftop Equipment, (ii) promptly pay any tax, license or permit fees charged pursuant to any Applicable Laws in connection with the installation, maintenance or use of the Rooftop Equipment and comply with all Applicable Laws pertaining to the use of the Rooftop Equipment, and (iii) pay for all necessary repairs, replacements to or maintenance of the Rooftop Equipment.

g. To the extent not installed by Tenant in accordance with the terms and conditions of the Tenant Work Letter, the installation of the Rooftop Equipment shall constitute alterations and shall be performed in accordance with and subject to the provisions of Article 8 of the Lease, including, without limitation, Tenant’s obligation to obtain Landlord’s prior consent to the size and other specifications of the Rooftop Equipment, which consent shall not be unreasonably withheld, conditioned or delayed.

6. Design Considerations.

a. All Rooftop Equipment shall be properly screened from view for aesthetic reasons, and must not be visible from street level.

b. The Antenna may not protrude above a height equal to the highest point of the Building structure.

c. Tenant, at Tenant’s sole cost and expense, shall install and maintain such fencing and other protective equipment and/or visual screening on or about the Rooftop Equipment as Landlord may reasonably determine.

d. The Rooftop Equipment shall be clearly marked to show the name, address, telephone number of the person to contact in case of emergency.

e. The Rooftop Equipment must be properly secured and installed so as not to be affected by high winds or other elements.

ADDENDUM 2

7. Compliance with Laws. Tenant’s rights set forth in this Rooftop Space Addendum shall be subject to all Applicable Laws. Landlord makes no representation that any such Laws permit such installation and operation, and Tenant shall be solely responsible to determine the feasibility and legality of installing the Rooftop Equipment. Without limiting the generality of the foregoing, if any testing, sampling or disclosures relating to rooftop equipment at the Building are required to satisfy OSHA or other governmental agencies (including for radio frequency [RF] or electromagnetic field [EMF] emissions), Tenant shall pay the costs of any such required tests and studies (or its prorata share thereof if the cost is properly shared by other rooftop users). Landlord shall have no liability or responsibility for the maintenance or compliance with laws of any towers, antennas or structures, including, without limitation, compliance with Part 17 of the Federal Communications Commissions’ Rules.

8. No Interference.

a. The Rooftop Equipment and operations shall not interfere with the communications configurations, frequencies or operating equipment of any existing users on the rooftop (collectively, “Existing Users”), including any equipment which the Existing Users have the right to install or operate but have not yet installed. Further, the Rooftop Equipment and operations shall comply with all non-interference rules of the Federal Communications Commission (“FCC”). Upon receipt of written notice of apparent interference by Tenant with Existing Users, Tenant shall have the responsibility to promptly terminate such interference or to demonstrate with competent information that the apparent interference in fact is not caused by Tenant’s Rooftop Equipment or operations. Subsequent to the date Tenant commences the operation of the Rooftop Equipment, Landlord shall not knowingly install or permit the installation of new equipment at the Building if such new equipment is likely to cause interference with the operation of the Rooftop Equipment, it being acknowledged that Landlord shall have no right or responsibility to prevent the installation of equipment any party has the right to install under the terms of its lease or occupancy agreement, or pursuant to applicable laws or regulations. With respect to equipment which the installing party has no right to install, Landlord shall require the installing party to first provide Tenant with notice of the equipment to be installed and Tenant shall then have the reasonable opportunity to meet with the party wishing to install the additional equipment so that any potential interference can be resolved to the satisfaction of Tenant. If in the future equipment is installed at the Building which interferes with the operation of the Rooftop Equipment, Tenant agrees to reasonably cooperate with such other user to resolve such interference in a mutually acceptable manner, subject to and in accordance with the rules of the FCC and the terms of any rights of Existing Users to operate new or revised equipment at the Building. Notwithstanding anything to the contrary herein, in no event shall Landlord have any liability with respect to interference with Tenant’s operations or any loss of business or profits, and Tenant’s sole remedy in the event of a breach of this provision shall be to pursue an action for injunctive relief.

b. In no event shall the Antenna or any Connecting Equipment damage or adversely affect or interfere with the normal operation of the Building (including, but not limited to mechanical, electrical, life-safety, structural systems, window washing or other maintenance functions of the Building). Tenant hereby agrees to indemnify, defend and hold Landlord harmless from and against any and all claims, costs, damages, expenses and liabilities (including reasonable attorneys’ fees) arising out of Tenant’s failure to comply with the provisions of this Rooftop Space Addendum, provided that Tenant’s indemnification obligation hereunder shall not apply to the extent same is caused by the gross negligence or willful misconduct of Landlord or its employees, agents or contractors. Should the use of the Rooftop Equipment by Tenant interfere with systems of the Building or telecommunications systems of any tenant, Tenant shall make such adjustments to the Rooftop Equipment or its related equipment as may be reasonably required by Landlord.

9. Access. Subject to the terms of this Rooftop Space Addendum, Tenant shall have the right to access its Rooftop Equipment during the hours of the Building more particularly set forth in Section 6.1.1 of the Lease. In exercising its right of access to the roof, Tenant agrees to cooperate and comply with any reasonable security procedures, access requirements and rules and regulations utilized by Landlord for the Building and further agrees not to unduly disturb or interfere with the business or other activities of Landlord or of other tenants or occupants of the Project.

ADDENDUM 2

10. Costs. Tenant shall be solely responsible for and shall pay all costs, expenses and taxes incurred in connection with the ownership, installation, operation, maintenance, use and removal of the Rooftop Equipment and the appurtenant equipment located in or on the Building, plus an administrative fee of five percent (5%).

11. Insurance. Tenant shall cause the insurance policies maintained by Tenant pursuant to the Lease to include the Rooftop Equipment and all related equipment and materials as part of Tenant’s insured property.

12. Indemnity. Tenant specifically agrees that the indemnification of Landlord by Tenant in accordance with the Lease is deemed to include any claims arising from the installation, operation, use, maintenance or removal of the Rooftop Equipment, and the provisions of Article 10 of the Lease are incorporated herein by reference.

13. Relocation. Landlord shall have the right, at its option and from time to time, upon not less than thirty (30) days prior notice to Tenant, to relocate the Rooftop Equipment to another location in the Building adequate to afford equivalent service to Tenant. Landlord shall pay the costs of relocation reasonably incurred by Tenant in connection with such substituted location, subject to adequate substantiation of such costs.

14. Removal and Restoration. Upon the expiration or earlier termination of the Lease, the Antenna and the Connecting Equipment shall be removed from the Building by Tenant, at Tenant’s sole cost and expense, and Tenant shall pay to repair any damage caused by such removal. If Tenant fails to remove the Antenna (if requested by Landlord to be removed) and any related Connecting Equipment (to the extent applicable) and repair the Building upon the expiration or earlier termination of the Lease, Landlord, upon thirty (30) days’ written notice to Tenant, may do so at Tenant’s expense. The provisions of this Section 14 shall survive the expiration or earlier termination of the Lease. If any tenant of the Building under a lease in effect on the date hereof has a right to an antenna, and Landlord is unable to accommodate such antenna (for any reason, including without limitation, physical or technical limitations regarding the use and operability thereof and any restrictions imposed by any governmental authority), but would be able to do so if the Antenna is removed, then Landlord shall have the right, at its option, upon not less than fifteen (15) days prior notice to Tenant, to require the removal of the Antenna by Tenant. Upon such removal, the rights contained in this Rooftop Space Addendum shall terminate, except for any accrued and unperformed obligations and liabilities hereunder.

15. Termination. Landlord shall have the right to terminate this Rooftop Space Addendum and the rights of Tenant hereunder (i) upon three (3) months prior written notice in the event Landlord determines that due to a change of use or any redevelopment of the Project or the Building, the Rooftop Equipment can no longer be operated (provided that any election to terminate in such event shall be made on a non discriminatory basis); or (ii) Tenant’s use unreasonably interferes with an essential building system or function, which interference cannot be remedied; or (iii) the operation of the Rooftop Equipment interferes with the equipment or operations of any of the existing tenants, licensees, or occupants of the Project. This Rooftop Space Addendum shall also terminate upon any destruction or condemnation affecting the use or operation of the Rooftop Equipment hereunder, unless otherwise agreed in writing by Landlord and Tenant. If this Rooftop Space Addendum is terminated as set forth herein, no amounts will be refunded or otherwise paid to Tenant and Tenant shall remain responsible for removing Tenant’s Rooftop Equipment and restoring the Building in accordance with the terms of this Rooftop Space Addendum.

ADDENDUM 2

16. Default. If any of the conditions set forth in this Rooftop Space Addendum are not complied with by Tenant, then such failure shall constitute a default by Tenant under the Lease, subject to the terms of Article 19 thereof.

17. Incorporation. Except to the extent modified or superseded by the terms and provisions of this Rooftop Space Addendum, the terms and provisions of the Lease are incorporated by reference herein and shall have the same force and effect as if set forth fully herein.
