2.1. LEASED PREMISES. Landlord leases to Tenant and Tenant leases from Landlord the Premises shown in Exhibit A (the “Premises”), containing approximately the floor area set forth in Item 8 of the Basic Lease Provisions (the “Floor Area”). The Premises consist of all of the Floor Area of the building identified in Item 2 of the Basic Lease Provisions (the “Building”), which is a portion of the project described in Item 2 (the “Project”). Tenant acknowledges that as of the date of this Lease, no commitment has been undertaken by Landlord to proceed with “Phase 2” of the Project. Landlord and Tenant stipulate and agree that the Floor Area of Premises set forth in Item 8 of the Basic Lease Provisions shall be binding on Landlord and Tenant for all purposes under this Lease. The Premises are a portion of certain real property which is leased by Landlord pursuant to that certain Ground Lease dated as of February 14, 2001 (as amended, the “Ground Lease”) by and between Landlord, as the “Lessee”, and the City of Santa Clara as successor-in-interest to The Redevelopment Agency of the City of Santa Clara (the “Ground Lessor”), a Memorandum of which Ground Lease was recorded February 16, 2001 as Document No. 15563490 in the Official Records of the County of Santa Clara, State of California.

2.2. ACCEPTANCE OF PREMISES. Except as set forth in this Lease, Tenant acknowledges that neither Landlord nor any representative of Landlord has made any representation or warranty with respect to the Premises, the Building or the Project or the suitability or fitness of either for any purpose. Tenant acknowledges that the flooring materials which may be installed within portions of the Premises located on the ground floor of the Building may be limited by the moisture content of the Building slab and underlying soils. Landlord represents that to the its actual knowledge, the moisture content of the underlying soils is such that there will be no limitation with respect to the flooring materials which may be installed within portions of the Premises located on the ground floor of the Building and that the Building slab will be constructed in a manner to prevent any moisture content.

3.1. GENERAL. The Term of this Lease (“Term”) shall commence (“Commencement Date”) on the later of (i) the Estimated Commencement Date set forth in Item 4 of the Basic Lease Provisions or (ii) the date upon which the Premises are tendered to Tenant with the Tenant Improvements (as defined in the Work Letter) constructed by Landlord pursuant to the Work Letter and the Premises “ready for occupancy”. The Term shall continue for the period set forth in Item 5 of the Basic Lease Provisions expiring on the final day of such period (the “Expiration Date”). Promptly following request by Landlord, the parties shall memorialize on a form provided by Landlord (the “Commencement Memorandum”) the actual Commencement Date and Expiration Date of this Lease; should Tenant fail to execute and return the Commencement Memorandum to Landlord within 5 business days (or provide specific written objections thereto within that period), then Landlord’s determination of the Commencement Date and Expiration Date as set forth in the Commencement Memorandum shall be conclusive. The Premises shall be deemed “ready for occupancy” if and when Landlord, to the extent applicable, (i) has substantially completed all the “Base, Shell and Core” work and the “Tenant Improvement Work” required to be completed by Landlord pursuant to the terms and conditions of the Work Letter attached to this Lease as Exhibit X but for minor punch list matters that do not materially interfere with the use of the Premises for Tenant’s regular business operations therein, and Landlord has obtained the requisite governmental approvals for Tenant’s legal occupancy of the Premises, and (ii) has delivered the Premises to Tenant and provided reasonable access to the Premises for Tenant so that the Premises may be used without unreasonable interference.

3.2. ESTIMATED COMMENCEMENT DATE. If Landlord, for any reason whatsoever, cannot deliver possession of the Premises to Tenant on or before the “Estimated Commencement Date” set forth in Item 4 of the Basic Lease Provisions, this Lease shall not be void or voidable nor shall Landlord be liable to Tenant for any resulting loss or damage. However, Tenant shall not be liable for any rent until the Commencement Date occurs as provided in Section 3.1 above, except that if Landlord’s failure to substantially complete all work required of Landlord and deliver possession of the Premises to Tenant pursuant to Section 3.1(i) above is attributable to any “Tenant Delay” described in the Work Letter attached to this Lease, then the Premises shall be deemed ready for occupancy, and Landlord shall be entitled to full performance by Tenant (including the payment of rent), as of the date Landlord would have been able to substantially complete such work and deliver the Premises to Tenant but for Tenant’s Delay(s) (but in no event sooner than the Estimated Commencement Date).

(a) Outside Date. If the Commencement Date has not occurred on or before July 15, 2013 (the “Outside Completion Date”), as the same may be extended pursuant to Section 3.3(d), then Tenant shall receive a credit against Basic Rent first coming due under this Lease in an amount equal to one (1) day of Basic Rent for every one (1) day that the Commencement actually occurs following the Outside Completion Date.

(b) Outside Date for Termination. If the Commencement Date has not occurred by October 15, 2013 (the “Outside Date for Termination”), as the same may be extended pursuant to Section 3.3(d), then the sole remedy of Tenant for such failure shall be the right to deliver a notice to Landlord (a “Termination Notice”) electing to terminate this Lease effective upon the date occurring five (5) business days following receipt by Landlord of the Termination Notice (the “Effective Date”). The Termination Notice must be delivered by Tenant to Landlord, if at all, not earlier than the Outside Date for Termination (as the same may be extended pursuant to the terms of Section 3.3(c), below) nor later than ten (10) business days after the Outside Date for Termination. The effectiveness of any such Termination Notice delivered by Tenant to Landlord shall be governed by the terms of this Section 3.3.

(c) Extension of Outside Date for Termination After Delivery of the Termination Notice. If Tenant delivers a Termination Notice to Landlord, then Landlord shall have the right to suspend the occurrence of the Effective Date for a period ending thirty (30) days after the Effective Date by delivering written notice to Tenant, prior to the Effective Date, that, in Landlord’s reasonable, good faith judgment, the Commencement Date will occur within thirty (30) days after the Effective Date (the “Termination Extension Notice”). If the Commencement Date occurs within such thirty (30) day suspension period, then the Termination Notice shall be of no force or effect, but if the Commencement Date does not occur within such thirty (30) day suspension period, then this Lease shall terminate upon the expiration of such thirty (30) day suspension period.

(d) Other Terms. The Outside Completion Date and the Outside Date for Termination shall be extended to the extent of any delay or delays caused by “Force Majeure,” as that term is defined below; provided, however, that (i) neither the Outside Completion Date nor the Outside Date for Termination shall be extended pursuant to this Section 3.3(d) by more than sixty (60) days for delay or delays caused by “Limited Force Majeure” (as that term is defined below) and (ii) neither the Outside Completion Date nor the Outside Date for Termination shall be extended beyond May 15, 2014 for delay or delays caused by Force Majeure in all events. Upon any termination as set forth in this Section 3.3. Landlord and Tenant shall be relieved from any and all liability to each other resulting hereunder except that Landlord shall return to Tenant any prepaid rent. Provided that Landlord pursues the construction of the Base, Core and Shell and the Tenant Improvement Work at all times in good faith, Tenant’s rights, as set forth in this Section 3.3, shall be Tenant’s sole and exclusive remedy at law or in equity for the failure of the Delivery Date to occur as set forth above. As used herein, “Force Majeure” shall mean any prevention, delay or stoppage due to any of the following: (i) strikes, lockouts, labor disputes, inability to obtain services, labor, or materials or reasonable substitutes therefor, governmental actions (not including a delay(s) in obtaining any building or construction permits required in order to construct the Base Building) and other similar causes beyond the reasonable control of Landlord (“Limited Force Majeure”), and (ii) acts of God, civil commotions, fire or other casualty, and other similar causes beyond the reasonable control of Landlord, but excluding financial inability by Landlord to perform.

(e) In the event the Outside Completion Date shall be extended for delays caused by Force Majeure, Landlord shall work in good faith with Tenant to find interim space for Tenant to occupy, at commercially reasonable rates, until the Commencement Date of this Lease does occur.

4.1. BASIC RENT. From and after the Commencement Date, Tenant shall pay to Landlord without abatement, deduction or offset a Basic Rent for the Premises in the total amount shown (including subsequent adjustments, if any) in Item 6 of the Basic Lease Provisions (the “Basic Rent”). If the Commencement Date is other than the first day of a calendar month, any rental adjustment shown in Item 6 shall be deemed to occur on the first day of the next calendar month following the specified monthly anniversary of the Commencement Date. The Basic Rent shall be due and payable in advance commencing on the Commencement Date and continuing thereafter on the first day of each successive calendar month of the Term, as prorated for any partial month. No demand, notice or invoice shall be required. An installment in the amount of 1 full month’s Basic Rent at the initial rate specified in Item 6 of the Basic Lease Provisions shall be delivered to Landlord within 30 days following the full execution and delivery of this Lease and shall be applied against the Basic Rent first due hereunder; the next installment of Basic Rent shall be due on the first day of the second calendar month of the Term, which installment shall, if applicable, be appropriately prorated to reflect the amount prepaid for that calendar month.

4.2. OPERATING EXPENSES. Tenant shall pay Tenant’s Share of Operating Expenses in accordance with Exhibit B of this Lease.

4.3. LETTER OF CREDIT. As security hereunder, Tenant shall deliver to Landlord, concurrently with Tenant’s execution of this Lease, an irrevocable standby Letter of Credit in the amount set forth in Item 9 of the Basic Lease Provisions (the “Letter of Credit”). The Letter of Credit shall be in form and with the substance of Exhibit K attached hereto (or otherwise acceptable to Landlord), and shall be issued by a financial institution acceptable to Landlord. Landlord hereby approves Silicon Valley Bank as an acceptable issuer of the Letter of Credit. The Letter of Credit shall be maintained in full force and effect through that date which is thirty (30) days after the Expiration Date of the Term of this Lease (including any extensions of the Term as provided in this Lease). In the event the Letter of Credit is not renewed by the issuing financial institution (or in the event that Tenant shall not deliver a replacement Letter of Credit from another financial institution acceptable to Landlord) on or before thirty (30) days prior to the then-scheduled expiration date of the Letter of Credit, then Landlord shall have the right to draw the full amount of such Letter of Credit and to hold such amount as part of the Security Deposit pursuant to Section 4.3 of this Lease. Upon any “Default” by Tenant (as hereinafter defined), Landlord shall be entitled to draw upon said Letter of Credit by the issuance of Landlord’s sole written demand to the issuing financial institution, which draw shall be in an amount necessary to pay any sum which Tenant is obligated to pay under this Lease notwithstanding any contrary provision of Civil Code Section 1950.7 including, without limitation, amounts determined by Landlord, in its reasonable discretion, (i) as the amounts due for prospective rent and for damages pursuant to Section 14.2(a)(i) of this Lease and/or Civil Code Section 1951.2, (ii) sums that Landlord may expend or be required to expend by reason of the Default by Tenant or any loss or damage that Landlord may suffer by reason of the Default, or (iii) costs incurred by Landlord in connection with the repair or restoration of the Premises pursuant to Section 15.3 of this Lease upon expiration or earlier termination of this Lease. Except as set forth in the preceding sentence, Landlord shall only draw upon the Letter of Credit following a Default and only to the extent required to cure the Default. Notwithstanding the foregoing, while the amount of any such draw shall be determined in Landlord’s reasonable discretion as provided in the foregoing, if the amount of any such draw(s) shall ultimately exceed the amount of damages actually incurred by Landlord as the result of Tenant’s default (as determined pursuant to the applicable provisions of Article 14 of this Lease), then Landlord shall promptly refund any such excess to Tenant. Any such draw shall be without waiver or any rights Landlord may have under this Lease or at law or in equity as a result of the default, as a setoff for full or partial compensation for the default. If any portion of the Letter of Credit is drawn after a Default by Tenant, Tenant shall within five (5) days after written demand by Landlord restore the Letter of Credit. Failure to so restore said Letter of Credit within said five (5) days shall be a default by Tenant under this Lease. Partial drawings upon said Letter of Credit shall be permitted. Notwithstanding anything in this Lease to the contrary, if Landlord draws upon the Letter of Credit solely due to Tenant’s failure to renew the Letter of Credit at least thirty (30) days before its expiration (i) such failure to renew shall not constitute a Default hereunder, and (ii) Tenant shall at any time thereafter be entitled to provide Landlord with a replacement Letter of Credit that satisfies the requirements hereunder, at which time Landlord shall return the cash proceeds of the original Letter of Credit drawn by Landlord.

5.1. USE. Tenant shall use the Premises only for the purposes stated in Item 3 of the Basic Lease Provisions and for no other use whatsoever; provided, however, that the Premises shall in no event be used for any of the following purposes: (i) offices of any agency or bureau of the United States or any state or political subdivision thereof; (ii) offices or agencies of any foreign governmental or political subdivision thereof; or (iii) schools, temporary employment agencies or other training facilities which are not ancillary to corporate, executive or professional office use. Tenant shall not do or permit anything to be done in or about the Premises which will in any way interfere with the rights or quiet enjoyment of other occupants of the Building or the Project, or use or allow the Premises to be used for any unlawful purpose, nor shall Tenant permit any nuisance or commit any waste in the Premises or the Project. Tenant shall not perform any work or conduct any business whatsoever in the Project other than inside the Premises. Tenant shall comply at its expense with all present and future laws, ordinances and requirements of all governmental authorities that pertain to Tenant or its use of the Premises. Notwithstanding anything to the contrary contained in this Section 5.1, in the event Tenant’s obligation for compliance with all future and present laws, ordinances, restrictions, regulations, orders, rules and requirements of all governmental authorities, and with all present and future covenants, conditions, easements or restrictions now or hereafter affecting or encumbering the Building and/or the Project, results in a “capital” expenditure on Tenant’s part (or Tenant’s being obligated to reimburse Landlord for a “capital” expenditure), Tenant shall only be responsible for the amortized cost of such “capital” expenditure (amortized at a market cost of funds as reasonably determined by Landlord) over the useful life of said improvement during the Term, except in the event each obligation for capital expenditure is required due to Tenant’s particular use of the Premises (in which case Tenant shall be fully responsible for the entire cost of such “capital” expenditure).

5.2. SIGNS. Provided Tenant continues to lease the entire Premises, Tenant shall have the exclusive right to two (2) exterior “building top” signs (one facing the front of the Building and one facing the rear of the Building) and one (1) “eye brow” sign on the facade of the Building, and the non-exclusive right to its pro-rata share of any monument signage which may be constructed for the Building, for Tenant’s name and graphics in location to be designated by Landlord, and subject to Landlord’s right of prior approval that such exterior signage is in compliance with the Signage Criteria (defined below). Subject to the approval of the City, Landlord hereby approves Tenant’s “building top” signage as shown on Exhibit M attached hereto. Except as provided in the foregoing, Tenant shall have no right to maintain signs in any location in, on or about the Project and shall not place or erect any signs that are visible from the exterior of the Building. The size, design, graphics, material, style, color and other physical aspects of any permitted sign shall be subject to Landlord’s written determination, as determined solely by Landlord, prior to installation, that signage is in compliance with any requirements of the City, and any covenants, conditions or restrictions encumbering the Premises and Landlord’s signage program for the Project, as in effect from time to time (“Signage Criteria”). Prior to placing or erecting any such signs, Tenant shall obtain and deliver to Landlord a copy of any applicable municipal or other governmental permits and approvals. Tenant shall be responsible for all costs of any permitted sign, including, without limitation, the fabrication, installation, maintenance and removal thereof and the cost of any permits therefor. If Tenant fails to maintain its sign in good condition, or if Tenant fails to remove same upon termination of this Lease and repair and restore any damage caused by the sign or its removal, Landlord may do so at Tenant’s expense. Landlord shall have the right to temporarily remove any signs in connection with any repairs or maintenance in or upon the Building. The term “sign” as used in this Section shall include all signs, designs, monuments, displays, advertising materials, logos, banners, projected images, pennants, decals, pictures, notices, lettering, numerals or graphics. Subject to the provisions for an “Objectionable Name” as hereinafter provided, the parties agree that Tenant’s signage rights shall be assignable to any permitted assignee under this Lease. Tenant’s signage shall not have a name which relates to an entity which is of a character or reputation, or is associated with a political faction or orientation, which is inconsistent with the quality of the Project, or which would otherwise reasonably offend a landlord of comparable institutionally owned office building located near the Building (an “Objectionable Name”). The parties hereby agree that the name “Arista Networks, Inc.” or any reasonable derivation thereof, shall not be deemed an Objectionable Name.

(a) For purposes of this Lease, the term “Hazardous Materials” means (i) any “hazardous material” as defined in Section 25501 (o) of the California Health and Safety Code, (ii) hydrocarbons, polychlorinated biphenyls or asbestos, (iii) any toxic or hazardous materials, substances, wastes or materials as defined pursuant to any other applicable state, federal or local law or regulation, and (iv) any other substance or matter which may result in liability to any person or entity as a result of such person’s possession, use, storage, release or distribution of such substance or matter under any statutory or common law theory.

(b) Tenant shall not cause or knowingly permit its agents, employees, contractors, licensees or invitees to bring upon, store, use, generate, release or dispose of any Hazardous Materials on, under, from or about the Premises (including without limitation the soil and groundwater thereunder) without the prior written consent of Landlord, which consent may be given or withheld in Landlord’s sole and absolute discretion. Notwithstanding the foregoing, Tenant shall have the right, without obtaining prior written consent of Landlord, to utilize within the Premises collectively, the “Permitted HazMats”): (i) a reasonable quantity of standard office products that may contain Hazardous Materials (such as photocopy toner, “White Out”, and the like), provided however, that Tenant shall maintain such products in their original retail packaging, shall follow all instructions on such packaging with respect to the storage, use and disposal of such products; and (ii) those Hazardous Materials in such quantities and in such manner as described in the Survey Form delivered to Landlord prior to the execution of this Lease. Tenant shall comply with all applicable laws with respect to the Permitted Hazmats, and all of the other terms and provisions of this Section 5.3 shall apply with respect to Tenant’s storage, use and disposal of all Permitted Hazmats. Landlord may, in its sole and absolute discretion, place such conditions as Landlord deems appropriate with respect to Tenant’s use, storage and/or disposal of any other Hazardous Materials requiring Landlord’s consent, including without limitation, conditions for proper containment and ventilation of such Hazardous Materials. Tenant understands that Landlord may utilize an environmental consultant to assist in determining conditions of approval in connection with the storage, use, release, and/or disposal of Hazardous Materials by Tenant on or about the Premises, and/or to conduct periodic inspections of the storage, generation, use, release and/or disposal of such Hazardous Materials by Tenant on and from the Premises, and in the event any violations of this Section 5.3 are found, then Tenant agrees that any costs incurred by Landlord in connection therewith shall be reimbursed by Tenant to Landlord as additional rent hereunder upon demand.

(c) Prior to the execution of this Lease, Tenant shall complete, execute and deliver to Landlord a Hazardous Material Survey Form (the “Survey Form”) in the form of Exhibit J attached hereto. The completed Survey Form shall be deemed incorporated into this Lease for all purposes, and Landlord shall be entitled to rely fully on the information contained therein. On each anniversary of the Commencement Date until the expiration or sooner termination of this Lease, Tenant shall disclose to Landlord in writing the names and amounts of all Hazardous Materials which were stored, generated, used, released and/or disposed of on, under or about the Premises by Tenant or its agents, employees, contractors, licensees, subtenants or invitees for the twelve-month period prior thereto, and which Tenant desires to store, generate, use, release and/or dispose of on, under or about the Premises for the succeeding twelve-month period. In addition, to the extent Tenant is permitted to utilize Hazardous Materials upon the Premises, Tenant shall promptly provide Landlord with complete and legible copies of all the following environmental documents relating thereto: reports filed pursuant to any self-reporting requirements; permit applications, permits, monitoring reports, emergency response or action plans, workplace exposure and community exposure warnings or notices and all other reports, disclosures, plans or documents (even those which may be characterized as confidential) relating to water discharges, air pollution, waste generation or disposal, and underground storage tanks for Hazardous Materials; orders, reports, notices, listings and correspondence (even those which may be considered confidential) of or concerning the release, investigation, compliance, cleanup, remedial and corrective actions, and abatement of Hazardous Materials; and all complaints, pleadings and other legal documents filed by or against Tenant related to Tenant’s storage, generation, use, release and/or disposal of Hazardous Materials.

(d) Landlord and its agents shall have the right, but not the obligation, to inspect, sample and/or monitor the Premises and/or the soil or groundwater thereunder at any time to determine whether Tenant is complying with the terms of this Section 5.3, and in connection therewith Tenant shall provide Landlord with full access to all facilities, records and personnel related thereto. If Tenant is not in compliance with any of the provisions of this Section 5.3, or in the event of a release of any Hazardous Material on, under, from or about the Premises caused or knowingly permitted by Tenant, its agents, employees, contractors, licensees, subtenants or invitees, Landlord and its agents shall have the right, but not the obligation, without limitation upon any of Landlord’s other rights and remedies under this Lease, to immediately enter upon the Premises without notice and to discharge Tenant’s obligations under this Section 5.3 at Tenant’s expense, including without limitation the taking of emergency or long-term remedial action. Landlord and its agents shall endeavor to minimize interference with Tenant’s business in connection therewith, but shall not be liable for any such interference. In addition, Landlord, at Tenant’s expense, shall have the right, but not the obligation, to join and participate in any legal proceedings or actions initiated in connection with any claims arising out of the storage, generation, use, release and/or disposal by Tenant or its agents, employees, contractors, licensees, subtenants or invitees of Hazardous Materials on, under, from or about the Premises.

(e) If the storage, use, generation, release or disposal presence of any Hazardous Materials on, under, from or about the Premises or the Project caused or knowingly permitted by Tenant or its agents, employees, contractors, licensees, subtenants, or invitees results in (i) injury to any person, (ii) injury to or any contamination of the Premises or the Project, or (iii) injury to or contamination of any real or personal property wherever situated, Tenant, at its expense, shall promptly take all actions necessary to return the Premises and the Project and any other affected real or personal property owned or leased by Landlord to the condition existing prior to the introduction of such Hazardous Materials and to remedy or repair any such injury or contamination, including without limitation, any cleanup, remediation, removal, disposal, neutralization or other treatment of any such Hazardous Materials as required by law. Notwithstanding the foregoing, Tenant shall not, without Landlord’s prior written consent, which consent may be given or withheld in Landlord’s sole and absolute discretion, take any remedial action in response to the presence of any Hazardous Materials on, under, from or about the Premises or the Project or any other affected real or personal property owned or leased by Landlord or enter into any similar agreement, consent, decree or other compromise with any governmental agency with respect to any Hazardous Materials claims; provided however, Landlord’s prior written consent shall not be necessary in the event that the presence of Hazardous Materials on, under, from or about the Premises or the Project or any other affected real or personal property owned by Landlord (i) imposes an immediate threat to the health, safety or welfare of any individual and (ii) is of such a nature that an immediate remedial response is necessary and it is not possible to obtain Landlord’s consent before taking such action. To the fullest extent permitted by law, Tenant shall indemnify, hold harmless, protect and defend (with attorneys reasonably acceptable to Landlord) Landlord and any successors to all or any portion of Landlord’s interest in the Premises, and Ground Lessor and any successors to Ground Lessor’s interest under the Ground Lease, from and against any and all liabilities, losses, damages, diminution in value, judgments, fines, demands, claims, recoveries, deficiencies, costs and expenses (including without limitation reasonable attorneys’ fees, court costs and other professional expenses), whether foreseeable or unforeseeable, arising directly or indirectly out of the use, generation, storage, treatment, release, on- or off-site disposal or transportation of

Hazardous Materials on, into, from, under or about the Premises, the Building or the Project Landlord caused or knowingly permitted by Tenant, its agents, employees, contractors, licensees, subtenants or invitees. Such indemnity obligation shall specifically include, without limitation, the cost of any required or necessary repair, restoration, cleanup or detoxification of the Premises, the Building and the Project, the preparation of any closure or other required plans, whether such action is required or necessary during the Term or after the expiration of this Lease and any loss of rental due to the inability to lease the Premises or any portion of the Building or Project as a result of such Hazardous Materials, the remediation thereof or any repair, restoration or cleanup related thereto. If it is at any time discovered that Tenant may have knowingly permitted its agents, employees, contractors, licensees, subtenants or invitees to release any Hazardous Materials on, under, from or about the Premises, the Building or the Project, or caused such release, Tenant shall, at Landlord’s request, immediately prepare and submit to Landlord a comprehensive plan, subject to Landlord’s approval, specifying the actions to be taken by Tenant to return the Premises, the Building or the Project to the condition existing prior to the introduction of such Hazardous Materials. Upon Landlord’s approval of such plan, Tenant shall, at its expense, and without limitation of any rights and remedies of Landlord under this Lease or at law or in equity, immediately implement such plan and proceed to cleanup, remediate and/or remove all such Hazardous Materials in accordance with all applicable laws and as required by such plan and this Lease. The provisions of this Section 5.3(e) shall expressly survive the expiration or sooner termination of this Lease.

(f) Landlord hereby discloses to Tenant, and Tenant hereby acknowledges, certain facts relating to Hazardous Materials at the Project known by Landlord to exist as of the date of this Lease, as more particularly described in Exhibit H attached hereto. Tenant shall have no liability or responsibility with respect to the Hazardous Materials facts described in Exhibit H, nor with respect to any Hazardous Materials which were not caused or knowingly permitted by Tenant, its agents, employees, contractors, licensees, subtenants or invitees. Notwithstanding the preceding two sentences, Tenant agrees to notify its agents, employees, contractors, licensees, subtenants, and invitees of any exposure or potential exposure to Hazardous Materials at the Premises that Landlord brings to Tenant’s attention. Landlord acknowledges and agrees with Tenant that the Hazardous Materials described on Exhibit H shall not be deemed to be “knowingly permitted” by Tenant for any purposes under this Lease.

(g) Landlord shall take responsibility, at its sole cost and expense, for any clean-up, remediation, removal, disposal, neutralization, monitoring, investigation or other treatment of, or response to, those Hazardous Materials conditions described in Section 5.3(f) above for which Tenant has no liability or responsibility, to the extent that such cleanup, remediation, removal, disposal, neutralization, monitoring, investigation or other treatment or response is required by applicable law, or to the extent that a failure to so cleanup, remediate, remove, dispose, neutralize, monitor, investigate or otherwise treat or respond to such Hazardous Materials conditions would be a violation of applicable law. The foregoing obligation on the part of Landlord shall include the reasonable costs (including, without limitation, reasonable attorney’s fees) of defending Tenant from and against any legal action or proceeding instituted by any governmental agency or other third party (excluding Tenant’s agents, employees, contractors, licensees, subtenants or invitees) in connection with such clean-up, remediation, removal, disposal, neutralization, monitoring, investigation or other treatment of or response to such conditions, provided that Tenant promptly tenders such defense to Landlord.

(h) Except as disclosed in Section 5.3(f) above (and/or as may otherwise be disclosed to Tenant in writing), Landlord warrants that, to “Landlord’s knowledge” (as hereinafter defined), there are no Hazardous Materials in or about the Premises which are in violation of any applicable federal, state or local law, ordinance or regulation. As used herein, “Landlord’s knowledge” shall mean the actual knowledge, without duty of inquiry or investigation, of the current employees or authorized agents of Landlord responsible for Hazardous Materials compliance matters.

6.1. UTILITIES AND SERVICES. Landlord and Tenant shall be responsible to furnish those utilities and services to the Premises to the extent provided in Exhibit C, subject to the conditions and payment obligations and standards set forth in this Lease. Landlord shall not be liable for any failure to furnish any services or utilities when the failure is the result of any accident or other cause beyond Landlord’s reasonable control, nor shall Landlord be liable for damages resulting from power surges or any breakdown in telecommunications facilities or services. Landlord’s temporary inability to furnish any services or utilities shall not entitle Tenant to any damages, relieve Tenant of the obligation to pay rent or constitute a constructive or other eviction of Tenant, except that Landlord shall diligently attempt to restore the service or utility promptly. Tenant shall comply with all rules and regulations which Landlord may reasonably establish for the provision of services and utilities, and shall cooperate with all reasonable conservation

practices established by Landlord. Landlord shall at all reasonable times have free access to all electrical and mechanical installations of Landlord. Landlord shall not charge Tenant for Tenant’s use of any existing conduit space in the Building nor for any conduit space installed by Tenant in the Building in order to connect Tenant’s voice/data and other utility cabling in the Building. Landlord shall provide Tenant, and Tenant’s contractor, with access to all existing telecommunications copper and fiber facilities in the Building.

Notwithstanding the foregoing, if as a result of the direct actions of Landlord, its employees, contractors or authorized agents, for more than three (3) consecutive business days following written notice to Landlord there is no HVAC or electricity services to all or a portion of the Premises or such an interruption of other essential utilities and building services, such as fire protection or water, so that all or a portion of the Premises cannot be used by Tenant, then Tenant’s Basic Rent (or an equitable portion of such Basic Rent to the extent that less than all of the Premises are affected) shall thereafter be abated until the Premises are again usable by Tenant; provided, however, that if Landlord is diligently pursuing the repair of such utilities or services and Landlord provides substitute services reasonably suitable for Tenant’s purposes, as for example, bringing in portable air-conditioning equipment, then there shall not be an abatement of Basic Rent. The foregoing provisions shall be Tenant’s sole recourse and remedy in the event of such an interruption of services, and shall not apply in case of the actions of parties other than Landlord, its employees, contractors or authorized agents, or in the case of damage to, or destruction of, the Premises (which shall be governed by the provisions of Article 11 of the Lease). Any disputes concerning the foregoing provisions shall be submitted to and resolved by shall be decided by the JAMS/ENDISPUTE (“JAMS”), or its successor, with such arbitration to be held in Santa Clara County, California, unless the parties mutually agree otherwise. Within ten (10) business days following submission to JAMS, JAMS shall designate three arbitrators and each party may, within five (5) business days thereafter, veto one of the three persons so designated. If two different designated arbitrators have been vetoed, the third arbitrator shall hear and decide the matter. If less than two (2) arbitrators are timely vetoed, JAMS shall select a single arbitrator from the non-vetoed arbitrators originally designated by JAMS, who shall hear and decide the matter. Any arbitration pursuant to this section shall be decided within thirty (30) days of submission to JAMS. The decision of the arbitrator shall be final and binding on the parties. All costs associated with the arbitration shall be awarded to the prevailing party as determined by the arbitrator.

6.2. OPERATION AND MAINTENANCE OF COMMON AREAS. During the Term, Landlord shall operate all Common Areas within the Project in good condition and repair in substantially the same condition as originally constructed. The term “Common Areas” shall mean all areas within the Building and exterior areas in the Project which are not held for exclusive use by persons entitled to occupy space, including without limitation parking areas and structures, driveways, sidewalks, landscaped and planted areas, hallways and interior stairwells not located within the premises of any tenant in the Building, common electrical rooms, entrances and lobbies, elevators, and restrooms in the Building not located within the Premises, electrical rooms within the Building, and all other exterior appurtenant areas and improvements within the Project provided by Landlord for the common use of Landlord and tenants in the Project and their respective employees and invitees.

6.3. USE OF COMMON AREAS. The occupancy by Tenant of the Premises shall include the use of the Common Areas in common with Landlord and with all others for whose convenience and use the Common Areas may be provided by Landlord, subject, however, to compliance with Rules and Regulations described in Article 17 below. Landlord shall at all times during the Term have exclusive control of the Common Areas, and may restrain or permit any use or occupancy, except as otherwise provided in this Lease or in Landlord’s rules and regulations. Tenant shall keep the Common Areas clear of any obstruction or unauthorized use related to Tenant’s operations. Landlord may temporarily close any portion of the Common Areas for repairs, remodeling and/or alterations, to prevent a public dedication or the accrual of prescriptive rights, or for any other reasonable purpose. Landlord’s temporary closure of any portion of the Common Areas for such purposes shall not deprive Tenant of reasonable access to the Premises. Notwithstanding anything to the contrary in this Lease, so long as Tenant or any Permitted Transferee continues to lease the entire Building, Tenant shall have the exclusive right to use the patio area adjacent to the Building and identified on Exhibit L (the “Building Patio Area”) for purposes of outdoor seating and to serve as seating for Tenant’s cafeteria.

6.4. CHANGES AND ADDITIONS BY LANDLORD. Landlord reserves the right to make alterations or additions to the Building or the Project or to the attendant fixtures, equipment and Common Areas, and such change shall not entitle Tenant to any abatement of rent or other claim against Landlord. No such change shall deprive Tenant of reasonable access to or use of the Premises or reduce the number of parking spaces granted under this Lease.

7.1. TENANT’S MAINTENANCE AND REPAIR. Except as set forth in Section 7.2 below and subject to Landlord’s obligations expressly contained in Section 3 of Exhibit G attached to this Lease and further subject to Articles 11 and 12, Tenant at its sole expense shall make all repairs necessary to keep the Premises and all improvements and fixtures therein in the condition as existed on the Commencement Date, excepting ordinary wear and tear, casualty and condemnation. Notwithstanding Section 7.2 below, Tenant’s maintenance obligation shall include without limitation all appliances, interior glass, doors, door closures, hardware, fixtures, fire extinguisher equipment and other equipment installed in the Premises and all Alterations constructed by Tenant pursuant to Section 7.3 below, together with any “supplemental” HVAC equipment installed by Tenant or as part of the Tenant Improvement Work. All repairs and other work performed by Tenant or its contractors shall be subject to the terms of Sections 7.3 and 7.4 below. Alternatively, should Landlord or its management agent agree to make a repair on behalf of Tenant and at Tenant’s request, Tenant shall promptly reimburse Landlord as additional rent for all reasonable costs incurred (including Landlord’s “standard supervision fee” as hereinafter defined) upon submission of an invoice. Not by way of limitation of the foregoing, Tenant may request that Landlord contract directly for interior janitorial services for the Premises, the cost of which shall be reimbursed by Tenant as provided in the foregoing. As used herein, “standard supervision fee” shall mean (i) 15% for the cost of repairs of less of $5,000.00, (ii) 10% for costs of repairs of $5,000.00 to $10,000.00, and (iii) 5% for the cost of repairs of greater than $10,000.00. Notwithstanding anything to the contrary in this Section 7.1, Landlord shall perform and construct, and Tenant shall have no responsibility to perform or construct, any repair, maintenance or improvements of which Tenant notifies Landlord in writing and which require a “capital” expenditure; provided, however, that Tenant shall pay Tenant’s Share of such “capital expenditures” to the extent such costs are properly included in Operating Expenses.

7.2. LANDLORD’S MAINTENANCE AND REPAIR. Subject to Articles 11 and 12, Landlord shall provide service, replacement, maintenance and repair with respect to the heating, ventilating and air conditioning (“HVAC”) equipment of the Building (exclusive of any “supplemental” HVAC equipment) and shall maintain in good repair the Common Areas, roof (including the roof membrane), foundations, footings, the exterior surfaces of the exterior walls of the Building (including exterior glass), and the structural, electrical, life safety, mechanical and plumbing systems of the Building (including elevators, if any, serving the Building), except to the extent provided in Section 7.1 above. Landlord shall have the right to employ or designate any reputable person or firm, including any employee or agent of Landlord or any of Landlord’s affiliates or divisions, to perform any service, repair or maintenance function. Landlord need not make any other improvements or repairs except as specifically required under this Lease, and nothing contained in this Section 7.2 shall limit Landlord’s right to reimbursement from Tenant for maintenance, repair costs and replacement costs as provided elsewhere in this Lease. Notwithstanding any provision of the California Civil Code or any similar or successor laws to the contrary, Tenant understands that it shall not make repairs at Landlord’s expense or by rental offset. Except as provided in Section 11.1 and Article 12 below, there shall be no abatement of rent and no liability of Landlord by reason of any injury to or interference with Tenant’s business arising from the making of any repairs, alterations or improvements to any portion of the Building, including repairs to the Premises, nor shall any related activity by Landlord constitute an actual or constructive eviction; provided, however, that in making repairs, alterations or improvements, Landlord shall interfere as little as reasonably practicable with the conduct of Tenant’s business in the Premises. 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 any similar or successor laws now or hereafter in effect.

7.3. ALTERATIONS. Tenant shall make no alterations, additions, fixtures, or improvements (collectively referred to as “Alterations”) to the Premises without the prior written consent of Landlord, which consent shall not be unreasonably withheld. Notwithstanding the foregoing, Tenant may make Alterations to the Premises costing less than One Dollar ($1.00) per square foot of the improved portion of the Premises during each calendar year of the Term without Landlord’s consent, provided, however, that any Alterations which change the “Base, Core and Shell” (as hereinafter defined), or the electrical or mechanical systems of the Premises, or which require a governmental permit as a prerequisite to the construction thereof, shall require Landlord’s prior written consent, which shall not be unreasonably withheld. Notwithstanding anything to the contrary contained in either of the foregoing sentences, however, no Alterations shall: (i) affect the exterior of the Building or outside areas (or be visible from adjoining sites), or (ii) adversely affect or penetrate any of the structural portions of the Building, including but not limited to the roof, or (iii) fail to comply with any applicable governmental requirements, or (iv) interfere in any manner with the proper functioning of, or Landlord’s access to, any mechanical, electrical, plumbing or HVAC systems, facilities or equipment located in or serving the Building, or (v) diminish the value of the Premises including, without limitation, using lesser quality materials than those existing in the Premises, or (vi) alter or replace Standard Improvements. Further, in the event that any Alteration would result in a change from Landlord’s

building standard materials and specifications for the Project (“Standard Improvements”), then subject to Landlord’s election contained in the last paragraph of this Section 7.3, Tenant shall be responsible for the cost of replacing such non-standard improvement (“Non-Standard Improvement”) with the applicable Standard Improvement (“Replacements”) which Replacements shall be completed prior to the Expiration Date or earlier termination of this Lease. Landlord may impose, as a condition to its consent, any requirements that Landlord in its discretion may deem reasonable or desirable, including but not limited to a requirement that all work in excess of One Hundred Thousand Dollars ($100,000.00) be covered by a lien and completion bond satisfactory to Landlord and requirements as to the manner, time, and contractor for performance of the work. Without limiting the generality of the foregoing, Tenant shall use Landlord’s designated structural, mechanical and electrical contractors for all Alterations work affecting the structural, mechanical or electrical systems of the Building, so long as such designated contractors are reasonably available and provided such contractors’ fees are commercially reasonable. Should Tenant perform any Alterations work that triggers a requirement by any governmental entity to perform any ancillary Building modification, then Tenant shall promptly perform such work at its sole cost and expense, or, at Landlord’s option, fund the reasonable cost thereof to Landlord, in which event Landlord shall perform such work. Tenant shall obtain all required permits for the Alterations and shall perform the work in compliance with all applicable laws, regulations and ordinances with contractors reasonably acceptable to Landlord. Landlord shall be entitled to a supervision fee in the amount of 4% of the cost of such Alterations either requiring a permit from the City of Santa Clara or affecting any mechanical, electrical, plumbing, or HVAC systems, facilities, or equipment located in or serving the Building. Any request for Landlord’s consent shall be made in writing and shall contain architectural plans describing the work in detail reasonably satisfactory to Landlord. Landlord may elect to cause its architect to review Tenant’s architectural plans, and the reasonable cost of that review shall be reimbursed by Tenant. Should the Alterations proposed by Tenant and consented to by Landlord change the floor plan of the Premises, then Tenant shall, at its expense, furnish Landlord with as-built drawings and CAD disks compatible with Landlord’s systems. Alterations shall be constructed in a good and workmanlike manner using materials of a quality reasonably approved by Landlord. Unless Landlord otherwise agrees in writing, all Alterations affixed to the Premises, but excluding moveable trade fixtures, equipment, personal property, and furniture, shall become the property of Landlord and shall be surrendered with the Premises at the end of the Term, except that Landlord may, as provided in the last paragraph of this Section 7.3, require Tenant to remove by the Expiration Date, or sooner termination date of this Lease, all or any Alterations (including without limitation all telephone and data cabling) installed either by Tenant or by Landlord at Tenant’s request (collectively, the “Required Removables”), and subject to Landlord’s election contained in the last paragraph of this Section 7.3, to replace any non-Standard Improvements with Standard Improvements. In connection with its removal of Required Removables, Tenant shall repair any damage to the Premises arising from that removal and shall restore the affected area to its pre-existing condition, reasonable wear and tear excepted.

If Landlord conditions its consent on the same, Landlord shall have the right to require Tenant to remove any Alterations, and to replace the same in accordance with the applicable standards set forth above, as of the Expiration Date or sooner termination of this Lease; provided, however, that all telephone and data cabling installed by Tenant shall in all events be removed by Tenant as of the Expiration Date or sooner termination of this Lease. Any Alterations for which Landlord’s consent is not given, however, shall be subject to Landlord’s right, exercisable at any time, to require same to be removed (and replaced in accordance with the standards set forth above) at the Expiration Date or sooner termination of this Lease.

7.4. MECHANIC’S LIENS. Tenant shall keep the Premises free from any liens arising out of any work performed, materials furnished, or obligations incurred by or for Tenant. Upon request by Landlord, Tenant shall promptly cause any such lien to be released by posting a bond in accordance with California Civil Code Section 3143 or any successor statute. In the event that Tenant shall not, within 30 days following Tenant’s actual notice of the imposition of any lien, cause the lien to be released of record by payment or posting of a proper bond, Landlord shall have, in addition to all other available remedies, the right to cause the lien to be released by any means it deems proper, including payment of or defense against the claim giving rise to the lien. All reasonable expenses so incurred by Landlord, including Landlord’s attorneys’ fees, shall be reimbursed by Tenant promptly following Landlord’s demand, together with interest from the date of payment by Landlord at the maximum rate permitted by law until paid. Tenant shall give Landlord no less than 10 days’ prior notice in writing before commencing construction of any kind on the Premises.

7.5. ENTRY AND INSPECTION. Landlord shall at all reasonable times, upon not less than one (1) business day’s prior verbal or written notice (except in the case of emergencies), have the right to enter the Premises to inspect them, to supply services in accordance with this Lease, to make repairs and renovations as reasonably deemed necessary by Landlord, and to submit the Premises to prospective or actual purchasers or encumbrance holders (or, during the final twelve

months of the Term or when an uncured Default exists, to prospective tenants), all without being deemed to have caused an eviction of Tenant and without abatement of rent except as provided elsewhere in this Lease. If reasonably necessary, Landlord may temporarily close all or a portion of the Premises to perform repairs, alterations and additions. Except in emergencies, Landlord shall provide Tenant with reasonable prior verbal notice of entry. In exercising any of Landlord’s rights of entry, inspection, repair, maintenance and construction under this Lease, including, without limitation, under Sections 5.3(d), 6.1, 6.4 and this Section 7.5, Landlord shall comply with Tenant’s reasonable security measures and operating procedures and shall use commercially reasonable efforts to minimize any disruption to Tenant. Further, Landlord shall not exercise any such rights in any manner as would unreasonably interfere with Tenant’s use of, access to, or parking at the Premises.

(a) Except as otherwise specifically provided in this Article 9, Tenant may not, either voluntarily or by operation of law, assign, sublet, encumber, or otherwise transfer all or any part of Tenant’s interest in this Lease, or permit the Premises to be occupied by anyone other than Tenant (each, a “Transfer”), without Landlord’s prior written consent, which consent shall not unreasonably be withheld in accordance with the provisions of Section 9.1(b). For purposes of this Lease, references to any subletting, sublease or variation thereof shall be deemed to apply not only to a sublease effected directly by Tenant, but also to a sub-subletting or an assignment of subtenancy by a subtenant at any level. Except as otherwise specifically provided in this Article 9, no Transfer (whether voluntary, involuntary or by operation of law) shall be valid or effective without Landlord’s prior written consent and, at Landlord’s election, such a Transfer shall constitute a material default of this Lease. Landlord shall not be deemed to have given its consent to any Transfer by any other course of action, including its acceptance of any name for listing in the Building directory.

(b) Except as otherwise specifically provided in this Article 9, if Tenant or any subtenant hereunder desires to transfer an interest in this Lease, Tenant shall first notify Landlord in writing and shall request Landlord’s consent thereto. Tenant shall also submit to Landlord in writing: (i) the name and address of the proposed transferee; (ii) the nature of any proposed subtenant’s or assignee’s business to be carried on in the Premises; (iii) the terms and provisions of any proposed sublease or assignment (including without limitation the rent and other economic provisions, term, improvement obligations and commencement date); (iv) evidence that the proposed assignee or subtenant will comply with the requirements of Exhibit D to this Lease; and (v) any other information requested by Landlord and reasonably related to the Transfer. Landlord shall not unreasonably withhold its consent, provided: (1) the use of the Premises will be consistent with the provisions of this Lease and with Landlord’s commitment to other tenants of the Building and Project; (2) any proposed subtenant or assignee submits to Landlord all reasonable information as Landlord may request concerning the proposed subtenant or assignee, including, but not limited to, current financial statements; (3) the proposed assignee or subtenant is neither an existing tenant or occupant of the Project nor a prospective tenant with whom Landlord or Landlord’s affiliate has been “actively negotiating” (as herein defined) to become a tenant at the Project (provided Landlord has available space in the Project for such existing tenant or prospect); and (4) the proposed transferee is not an SDN (as defined below) and will not impose additional burdens or security risks on Landlord. As used herein, “actively negotiating” shall mean that the prospect shall have countered a written proposal from Landlord in writing within four (4) months prior to Tenant’s proposed transfer for the lease of space in the Building or the Project. If Landlord consents to the proposed Transfer, then the Transfer may be effected within 90 days after the date of the consent upon the terms described in the information furnished to Landlord; provided that any material change in the terms shall be subject to Landlord’s consent as set forth in this Section 9.1(b). Landlord shall approve or disapprove any requested Transfer within 15 business days following receipt of Tenant’s written notice and the information set forth above. Except in connection with a Permitted Transfer (as defined below), if Landlord approves the Transfer Tenant shall pay a transfer fee of $1,000.00 to Landlord concurrently with Tenant’s execution of a Transfer consent prepared by Landlord.

(c) Except in connection with a “Permitted Transfer” (as defined below), in the event of an assignment of this Lease or a subletting of more than fifty percent (50%) of the Floor Area of the Premises (in the aggregate) for all or substantially all of the remainder of the Term, in lieu of consenting to a proposed assignment or subletting, Landlord may elect to terminate this Lease in its entirety in the event of an assignment, or terminate this Lease as to the portion of the Premises proposed to be subleased with a proportionate abatement in the rent payable under this Lease, such termination to be effective on the date that the proposed sublease or assignment

would have commenced. Landlord may thereafter, at its option, assign or re-let any space so recaptured to any third party, including without limitation the proposed transferee identified by Tenant.

(d) Should any Transfer occur, Tenant shall, except in connection with a Permitted Transfer, promptly pay or cause to be paid to Landlord, as additional rent, 50% of any amounts paid by the assignee or subtenant, however described and whether funded during or after the Lease Term, to the extent such amounts are in excess of the sum of (i) the scheduled Basic Rent and Operating Expenses payable by Tenant hereunder (or, in the event of a subletting of only a portion of the Premises, the Basic Rent and Operating Expenses allocable to such portion as reasonably determined by Landlord) and (ii) the direct out-of-pocket costs, as evidenced by third party invoices provided to Landlord, incurred by Tenant to effect the Transfer (including, without limitation, brokerage commissions, legal fees and tenant improvements costs paid by Tenant in connection with such subletting or assignment).

(e) Notwithstanding anything in this Article 9 to the contrary, Tenant shall be permitted from time to time, with at least 30 days prior written notice to Landlord, to permit its clients or contractors (“Approved Users”) to temporarily occupy space within the Premises, provided that (a) Tenant does not separately demise such space and the Approved Users utilize, in common with Tenant, one common entryway to the Premises as well as certain shared central services, such as reception, photocopying and the like; (b) the Approved Users shall not occupy, in the aggregate, more than 25% of the Floor Area of the Premises; and (c) all Approved Users shall be clients or contractors of Tenant, and shall occupy space in the Premises only so long as such Approved Users are conducting at least 75% of their business at the Premises under contract with Tenant (or with any Affiliate of Tenant). If any Approved Users occupy any portion of the Premises as described herein, it is agreed that (i) in no event shall any use or occupancy of any portion of the Premises by any Approved User release or relieve Tenant from any of its obligations under this Lease; (ii) the Approved User and its employees, contractors and invitees visiting or occupying space in the Premises shall be deemed contractors of Tenant for purposes of Tenant’s indemnification obligations in Section 10.3; and (iii) in no event shall the occupancy of any portion of the Premises by Approved Users be deemed to create a landlord/tenant relationship between Landlord and such Approved Users, and, in all instances, Tenant shall be considered the sole tenant under the Lease notwithstanding the occupancy of any portion of the Premises by the Approved Users.

(f) Notwithstanding anything to the contrary contained in this Article 9, Landlord’s consent shall not be required and Tenant may, without Landlord’s prior written consent and without constituting an assignment or sublease hereunder, sublet the Premises or assign the Lease to (A) an entity controlling, under common control with or controlled by Tenant (“Affiliate”), (B) a successor entity related to Tenant by purchase, merger, consolidation, nonbankruptcy reorganization, or government action, or (C) a purchaser of substantially all of Tenant’s assets located in the Premises ((A), (B) and (C) are collectively referred to herein as “Permitted Transferees” and individually as a “Permitted Transferee”, and transfers to such Permitted Transferees shall be collectively referred to herein as “Permitted Transfers”), so long as (i) the net worth of the Permitted Transferee is at least equal to the net worth of Tenant immediately prior to the date of such Permitted Transfer, or, in Landlord’s reasonable determination, such Permitted Transferee has sufficient net worth to perform Tenant’s obligations under this Lease, evidence of which, satisfactory to Landlord, shall be presented to Landlord prior to such Permitted Transfer; provided, however that the provisions of this clause (i) shall not apply to transfers to an Affiliate, (ii) Tenant shall provide to Landlord, prior to such Permitted Transfer, written notice of such Permitted Transfer and such assignment documentation and other information as Landlord may reasonably require in connection therewith, and (iii all of the other terms and requirements Section 9.2 and 9.3 (but not of Section 9.1) shall apply with respect to such Permitted Transfer. A sale or transfer of Tenant’s capital stock shall not be deemed an assignment, subletting or any other transfer of this Lease or the Premises.

9.2. EFFECT OF TRANSFER. No subletting or assignment, even with the consent of Landlord, shall relieve Tenant, or any successor-in-interest to Tenant hereunder, of its obligation to pay rent and to perform all its other obligations under this Lease. Each assignee, other than Landlord, shall be deemed to assume all obligations of Tenant under this Lease and shall be liable jointly and severally with Tenant for the payment of all rent, and for the due performance of all of Tenant’s obligations, under this Lease. Such joint and several liability shall not be discharged or impaired by any subsequent modification or extension of this Lease. No transfer requiring Landlord’s consent shall be binding on Landlord unless any document memorializing the transfer is delivered to Landlord, both the assignee/subtenant and Tenant deliver to Landlord an executed consent to transfer instrument prepared by Landlord and consistent with the requirements of this Article, and the assignee/subtenant independently complies with all of the insurance requirements of Tenant as set forth in Exhibit D and evidence thereof is delivered to Landlord. The acceptance by Landlord of any payment due under this Lease from any other person shall not be deemed to be a waiver by Landlord of any provision of this Lease or to be a consent to any transfer. Consent by Landlord to one or more transfers shall not operate as a waiver or estoppel to the future enforcement by Landlord of its rights under this Lease.

9.3. SUBLEASE REQUIREMENTS. Any sublease, license, concession or other occupancy agreement entered into by Tenant shall be subordinate and subject to the provisions of this Lease, and if this Lease is terminated during the term of any such agreement, Landlord shall have the right to: (i) treat such agreement 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 (or licensor, as applicable) under such agreement. Landlord shall not, by reason of such attornment or the collection of sublease rentals, be deemed liable to the subtenant for the performance of any of Tenant’s obligations under the sublease. If Tenant is in Default (hereinafter defined), Landlord is irrevocably authorized to direct any transferee under any such agreement to make all payments under such agreement directly to Landlord (which Landlord shall apply towards Tenant’s obligations under this Lease) until such Default is cured. Tenant hereby irrevocably authorizes and directs any transferee, upon receipt of a written notice from Landlord stating that an uncured Default exists in the performance of Tenant’s obligations under this Lease, to pay to Landlord all sums then and thereafter due under the sublease. No collection or acceptance of rent by Landlord from any transferee shall be deemed a waiver of any provision of Article 9 of this Lease, an approval of any transferee, or a release of Tenant from any obligation under this Lease, whenever 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.

10.1. TENANT’S INSURANCE. Tenant, at its sole cost and expense, shall provide and maintain in effect the insurance described in Exhibit D. Evidence of that insurance must be delivered to Landlord prior to the Commencement Date.

10.2. LANDLORD’S INSURANCE. Landlord shall provide the following types of insurance, with or without deductible and in amounts and coverages as may be determined by Landlord in its reasonable discretion: property insurance, including fire, vandalism, malicious mischief and such other additional perils as may be included in a standard “special form” policy, subject to standard exclusions (such as, but not limited to, earthquake and flood exclusions), covering the full replacement value of the Building and the Project (the “Property Policy”). In addition, Landlord may, at its election, obtain insurance coverages for such other risks as Landlord or its Mortgagees may from time to time deem appropriate, including earthquake and commercial general liability coverage. Landlord shall not be required to carry insurance of any kind on any Alterations in the Premises installed by Tenant or its contractors or otherwise removable by Tenant (collectively, “Tenant Installations”), or on the “Tenant Improvements” constructed pursuant to the Work Letter, or on any trade fixtures, furnishings, equipment, interior plate glass, signs or items of personal property in the Premises, and Landlord shall not be obligated to repair or replace any of the foregoing items should damage occur. All proceeds of insurance maintained by Landlord upon the Building and Project shall be the property of Landlord, whether or not Landlord is obligated to or elects to make any repairs.

(a) To the fullest extent permitted by law, but subject to Section 10.5 below, Tenant shall defend, indemnify and hold harmless Landlord and Ground Lessor, and their respective agents, employees, lenders and affiliates, from and against any and all claims, liabilities, costs or expenses arising either before or after the Commencement Date from Tenant’s use or occupancy of the Premises, the Building or the Common Areas, or from the conduct of its business, or from any activity, work, or thing done, permitted or suffered by Tenant or its agents, employees, subtenants, vendors, contractors, invitees or licensees in or about the Premises, the Building or the Common Areas, or from any Default in the performance of any obligation on Tenant’s part to be performed under this Lease, or from any act or negligence of Tenant or its agents, employees, subtenants, vendors, contractors, invitees or licensees. Notwithstanding the foregoing, Tenant shall not be obligated to indemnify Landlord against any liability or expense to the extent it is ultimately determined that the same was caused by the sole negligence or willful misconduct of Landlord, its agents, contractors or employees. In cases of alleged negligence asserted by third parties against Landlord which arise out of, are occasioned by, or in any way attributable to Tenant, its agents, employees, contractors, licensees or invitees use and occupancy of the Building or the Common Areas, or from the conduct of its business or from any activity, work or thing done, permitted or suffered by Tenant or its agents, employees, invitees or licensees on Tenant’s part to be performed under this Lease, or from any negligence or willful misconduct of Tenant, its agents, employees, licensees or invitees, Tenant shall accept any tender of defense for Landlord and shall, notwithstanding any allegation of negligence or willful misconduct on the part of the Landlord, defend Landlord with counsel reasonably satisfactory to Landlord and protect and hold Landlord harmless and pay all costs, expenses and attorneys’ fees incurred in

connection with such litigation, provided that Tenant shall not be liable for any such injury or damage, and Landlord shall reimburse Tenant for the reasonable attorneys’ fees and costs for the attorney representing both parties, all to the extent and in the proportion that such injury or damage is ultimately determined by a court of competent jurisdiction (or in connection with any negotiated settlement agreed to by Landlord) to be attributable to the active negligence or willful misconduct of Landlord. Upon Landlord’s request, Tenant shall at Tenant’s sole cost and expense, retain a separate attorney reasonably selected by Landlord to represent Landlord in any such suit if Landlord reasonably determines that the representation of both Tenant and Landlord by the same attorney would cause a conflict of interest; provided, however, that to the extent and in the proportion that the injury or damage which is the subject of the suit is ultimately determined by a court of competent jurisdiction (or in connection with any negotiated settlement agreed to by Landlord) to be attributable to the active negligence or willful misconduct of Landlord, Landlord shall reimburse Tenant for the reasonable legal fees and costs of the separate attorney retained by Tenant.

(b) To the fullest extent permitted by law, but subject to the express limitations on liability contained in this Lease (including, without limitation, the provisions of Sections 10.5 and 14.8 of this Lease), Tenant shall not indemnify Landlord for, and Landlord shall defend, indemnify, protect, save and hold harmless Tenant, its agents and any and all affiliates of Tenant, including without limitation, any corporations, or other entities controlling, controlled by or under common control with Tenant, from and against, any and all claims, liabilities, costs or expenses arising either before or after the Commencement Date from the active negligence or willful misconduct of Landlord, its employees or authorized agents in connection with the operation, maintenance or repair of the Common Areas of the Building or Project. The provisions of this Subsection 10.3(b) shall expressly survive the expiration or sooner termination of this Lease.

10.4. LANDLORD’S NONLIABILITY. Subject only to the express indemnity obligations contained in Section 10.3(b) of this Lease but notwithstanding any other provision of this Lease to the contrary, Landlord shall not be liable to Tenant, its employees, agents and invitees, and Tenant hereby waives all claims against Landlord, its employees and agents for loss of or damage to any property, or any injury to any person, resulting from any condition including, but not limited to, acts or omissions (criminal or otherwise) of third parties and/or other tenants of the Project, or their agents, employees or invitees, fire, explosion, falling plaster, steam, gas, electricity, water or rain which may leak or flow from or into any part of the Premises or from the breakage, leakage, obstruction or other defects of the pipes, sprinklers, wires, appliances, plumbing, air conditioning, electrical works or other fixtures in the Building, whether the damage or injury results from conditions arising in the Premises or in other portions of the Building, except to the extent of the gross negligence or willful misconduct of Landlord, its employees or authorized agents in connection with the foregoing (but subject to Section 10.5 below). It is understood that any such condition may require the temporary evacuation or closure of all or a portion of the Building. Should Tenant elect to receive any service from a concessionaire, licensee or third party tenant of Landlord, Tenant shall not seek recourse against Landlord for any breach or liability of that service provider. Notwithstanding anything to the contrary contained in this Lease, in no event shall Landlord be liable for Tenant’s loss or interruption of business or income (including without limitation, Tenant’s consequential damages, lost profits or opportunity costs), or for interference with light or other similar intangible interests.

10.5. WAIVER OF SUBROGATION. Notwithstanding anything to the contrary contained in this Lease, Landlord and Tenant each hereby waives all rights of recovery against the other on account of loss and damage occasioned to the property of such waiving party to the extent that the waiving party is entitled to proceeds for such loss and damage under any property insurance policies carried or otherwise required to be carried by this Lease (including, without limitation, the Property Policy required of Landlord in the first sentence of Section 10.2 of this Lease); provided however, that the foregoing waiver shall not apply to the extent of Tenant’s obligation to pay deductibles under any such policies and this Lease. By this waiver it is the intent of the parties that neither Landlord nor Tenant shall be liable to any insurance company (by way of subrogation or otherwise) insuring the other party for any loss or damage insured against under any property insurance policies, even though such loss or damage might be occasioned by the negligence of such party, its agents, employees, contractors or invitees. The foregoing waiver by Tenant shall also inure to the benefit of Landlord’s management agent for the Building. All of Landlord’s and Tenant’s repair and indemnity obligations under this Lease shall be subject to the waiver contained in this Section 10.5.

(a) If the Building of which the Premises are a part is damaged as the result of an event of casualty, then subject to the provisions below, Landlord shall repair that damage as soon as reasonably possible unless Landlord reasonably determines that: (i) the Premises have been

materially damaged and there is less than 1 year of the Term remaining on the date of the casualty or (ii) proceeds necessary to pay the full cost of the repair are not available from Landlord’s Property Policy and/or from its other property insurance policies (if any), insurance, including without limitation earthquake insurance plus any additional amounts Tenant elects, at its option, to contribute, excluding, however, the deductible (for which Tenant shall be responsible to reimburse Landlord as a “Project Cost”, subject to the terms and limitations of Section (g) of Exhibit B attached to this Lease). Should Landlord elect not to repair the damage for one of the preceding reasons, Landlord shall so notify Tenant in the “Casualty Notice” (as defined below), and this Lease shall terminate as of the date of delivery of that notice.

(b) As soon as reasonably practicable following the casualty event but not later than 60 days thereafter, Landlord shall notify Tenant in writing (“Casualty Notice”) of Landlord’s election, if applicable, to terminate this Lease. If this Lease is not so terminated, the Casualty Notice shall set forth the anticipated period for repairing the casualty damage. If the anticipated repair period exceeds 270 days, then either party may elect to terminate this Lease by written notice to the other within 10 business days following delivery of the Casualty Notice. In addition, Tenant may terminate this Lease within 10 business days following receipt of such Casualty Notice if the casualty has occurred within the final twelve (12) months of the Term and such material damage has a materially adverse impact on Tenant’s continued use of the Premises.

(c) In the event that neither Landlord nor Tenant terminates this Lease pursuant to Section 11.1(b), Landlord shall, at Landlord’s sole cost and expense, repair all material damage to the Premises or the Building as soon as reasonably possible and this Lease shall continue in effect for the remainder of the Term. Upon notice from Landlord, Tenant shall assign or endorse over to Landlord (or to any party designated by Landlord) all property insurance proceeds payable to Tenant under Tenant’s insurance with respect to any Tenant Installations; and Landlord shall restore any such Tenant Installations. In the absence of any such notice from Landlord, restoration of the Tenant Installations shall be Tenant’s responsibility at its sole cost and expense.

(d) From and after the casualty event, the rental to be paid under this Lease shall be abated in the same proportion that the Floor Area of the Premises that is rendered unusable by the damage from time to time bears to the total Floor Area of the Premises.

(e) Notwithstanding, anything to the contrary contained in this Section 11.1, if for any reasons other than delays caused by Tenant, or other matters beyond Landlord’s reasonable control (not to exceed thirty (30) days in the aggregate), the Premises has not been substantially repaired within the time period specified in the Casualty Notice, then Tenant may, by written notice to Landlord given at any time thereafter but prior to the actual date of the substantial completion of the repair of the Premises or the Building, elect to terminate this Lease. Notwithstanding the foregoing, if at any time during the construction period, Landlord reasonably determines that the substantial completion of said repairs will be delayed beyond the time period specified in the Casualty Notice (for reasons other than Tenant-caused delays and/or force majeure delays not exceeding 30 days in the aggregate), then Landlord may notify Tenant in writing of such determination and of a new outside date for completion of such repairs, and Tenant must elect within ten (10) days of receipt of such notice to either terminate this Lease or waive its right to terminate this Lease provided such repairs are substantially completed prior to the new outside date established by Landlord in such notice to Tenant. Tenant’s failure to elect to terminate this Lease within such ten (10) day period shall be deemed Tenant’s waiver of its right to terminate this Lease as provided in this paragraph as to the previous outside date, but not as to the new outside date established by said notice.

11.2. LEASE GOVERNS. Tenant agrees that the provisions of this Lease, including without limitation Section 11.1, shall govern any damage or destruction and shall accordingly supersede any contrary statute or rule of law.

Either party may terminate this Lease if any material part of the Premises is taken or condemned for any public or quasi-public use under Law, by eminent domain or private purchase in lieu thereof (a “Taking”). Landlord shall also have the right to terminate this Lease if there is a Taking of any portion of the Building or Project which would have a material adverse effect on Landlord’s ability to profitably operate the remainder of the Building. The terminating party shall provide written notice of termination to the other party within 45 days after it first receives notice of the Taking. The termination shall be effective as of the effective date of any order granting possession to, or vesting legal title in, the condemning authority. If this Lease is not terminated, Basic Rent and Tenant’s Share of Operating Expenses shall be appropriately adjusted to account for any reduction in the square footage of the Building or Premises. All compensation awarded for a Taking shall be the property of Landlord and the right to receive compensation or proceeds in connection with a Taking are expressly waived by Tenant; provided, however, Tenant may file a

claim for Tenant’s personal property and fixtures and Tenant’s relocation expenses, and business interruption expenses recoverable from the taking authority. If only a part of the Premises is subject to a Taking and this Lease is not terminated, Landlord, with reasonable diligence, will restore the remaining portion of the Premises as nearly as practicable to the condition immediately prior to the Taking. Tenant agrees that the provisions of this Lease shall govern any Taking and shall accordingly supersede any contrary statute or rule of law.

13.1. SUBORDINATION. Tenant accepts this lease subject and subordinate: (i) to the Ground Lease, and (ii) to any mortgage(s), deed(s) of trust, other ground lease(s) or other lien(s) subsequently arising upon the Building or the Project, and to renewals, modifications, refinancings and extensions thereof (collectively referred to as a “Mortgage”); provided, that so long as no uncured Default exists under this Lease, Tenant’s possession and quiet enjoyment of the Premises shall not be disturbed and this Lease shall not terminate in the event of termination of any such Mortgage, or the foreclosure of any such Mortgage, to which this Lease has been subordinated pursuant to this Section. The party having the benefit of a Mortgage being referred to as a “Mortgagee”). Tenant shall execute a nondisturbance subordination and attornment agreement in commercially reasonable form and content (the “SNDA”), upon not less than twenty (20) days prior written notice from Landlord, in favor of any prospective Mortgagee, provided that such SNDA shall provide a nondisturbance covenant benefitting Tenant. Alternatively, a Mortgagee shall have the right at any time to subordinate its Mortgage to this Lease. Tenant agrees that any purchaser at a foreclosure sale or lender taking title under a deed in lieu of foreclosure in connection with any Mortgagee shall not be responsible for any act or omission of a prior landlord, shall not be subject to any offsets or defenses Tenant may have against a prior landlord, and shall not be liable for the return of the Security Deposit not actually recovered by such purchaser nor bound by any rent paid in advance of the calendar month in which the transfer of title occurred; provided that the foregoing shall not release the applicable prior landlord from any liability for those obligations. Tenant acknowledges that Mortgagees and their successors-in-interest are intended third party beneficiaries of this Section 13.1.

Landlord represents and warrants to Tenant that there are no Mortgages encumbering the Building or the Project as of the execution of this Lease, except for the Ground Lease. Landlord shall obtain, as a condition precedent to the Commencement Date, the Nondisturbance Agreement in form and content of Exhibit I attached to this Lease from the Ground Lessor for the benefit of Tenant.

13.2. ESTOPPEL CERTIFICATE. Tenant shall, within 20 days following the request of Landlord, execute and deliver a commercially reasonable estoppel certificate in favor of those parties as are reasonably requested by Landlord (including a Mortgagee or a prospective purchaser of the Building or the Project).

14.1. TENANT’S DEFAULTS. In addition to any other event of default set forth in this Lease, the occurrence of any one or more of the following events (following the expiration of any cure period set forth below, if any is provided) shall constitute a “Default” by Tenant:

(a) The failure by Tenant to make any payment of Rent required to be made by Tenant, as and when due, where the failure continues for a period of 5 days after written notice from Landlord to Tenant. The term “Rent” as used in this Lease shall be deemed to mean the Basic Rent and all other sums required to be paid by Tenant to Landlord pursuant to the terms of this Lease.

(b) Except as provided in Article 9 of this Lease, the assignment, sublease, encumbrance or other Transfer of the Lease by Tenant, either voluntarily or by operation of law, whether by judgment, execution, transfer by intestacy or testacy, or other means, where such assignment, sublease, encumbrance or other transfer remains in effect for a period of fifteen (15) days after written notice from Landlord to Tenant.

(c) The discovery by Landlord that any financial statement provided by Tenant, or by any affiliate, successor or guarantor of Tenant, was materially false.

(d) The failure by Tenant to deliver an SNDA or an estoppel certificate in form and content required by the applicable provisions of Section 13.1 of this Lease, where the failure continues for a period of 10 days after written notice from Landlord to Tenant.

(e) Except where a specific time period is otherwise set forth for Tenant’s performance in this Lease (in which event the failure to perform by Tenant within such time period shall be a Default), the failure or inability by Tenant to observe or perform any of the covenants or

provisions of this Lease to be observed or performed by Tenant, other than as specified in any other subsection of this Section 14.1(e), where the failure continues for a period of 30 days after written notice from Landlord to Tenant. However, if the nature of the failure is such that more than 30 days are reasonably required for its cure, then Tenant shall not be deemed to be in Default if Tenant commences the cure within 30 days, and thereafter diligently pursues the cure to completion.

The notice periods provided herein are in lieu of, and not in addition to, any notice periods provided by law, and Landlord shall not be required to give any additional notice under California Code of Civil Procedure Section 1161, or any successor statute, in order to be entitled to commence an unlawful detainer proceeding (but the foregoing shall not limit or modify the cure periods specifically set forth in this Section 14).

(a) Upon the occurrence of any Default by Tenant, then in addition to any other remedies available to Landlord, Landlord may exercise the following remedies:

(i) Landlord may terminate Tenant’s right to possession of the Premises by any lawful means, in which case this Lease shall terminate and Tenant shall immediately surrender possession of the Premises to Landlord. Such termination shall not affect any accrued obligations of Tenant under this Lease. Upon termination, Landlord shall have the right to reenter the Premises and remove all persons and property. Landlord shall also be entitled to recover from Tenant:

(1) The worth at the time of award of the unpaid Rent which had been earned at the time of termination;

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

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

(4) Any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result from Tenant’s default, including, but not limited to, the cost of recovering possession of the Premises, commissions and other expenses of reletting, including necessary repair, renovation, improvement and alteration of the Premises for a new tenant, reasonable attorneys’ fees, and any other reasonable costs; and

(5) At Landlord’s election, all other amounts in addition to or in lieu of the foregoing as may be permitted by law. Any sum, other than Basic Rent, shall be computed on the basis of the average monthly amount accruing during the 24 month period immediately prior to Default, except that if it becomes necessary to compute such rental before the 24 month period has occurred, then the computation shall be on the basis of the average monthly amount during the shorter period. As used in subparagraphs (1) and (2) above, the “worth at the time of award” shall be computed by allowing interest at the rate of 10% per annum. As used in subparagraph (3) above, the “worth at the time of award” shall be computed by discounting the amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus 1%.

(ii) Landlord may elect not to terminate Tenant’s right to possession of the Premises, in which event Landlord may continue to enforce all of its rights and remedies under this Lease, including the right to collect all rent as it becomes due. Efforts by the Landlord to maintain, preserve or relet the Premises, or the appointment of a receiver to protect the Landlord’s interests under this Lease, shall not constitute a termination of the Tenant’s right to possession of the Premises. In the event that Landlord elects to avail itself of the remedy provided by this subsection (ii), Landlord shall not unreasonably withhold its consent to an assignment or subletting of the Premises subject to the reasonable standards for Landlord’s consent as are contained in this Lease.

(b) The various rights and remedies reserved to Landlord in this Lease or otherwise shall be cumulative and, except as otherwise provided by California law, Landlord may pursue any or all of its rights and remedies at the same time. No delay or omission of Landlord to exercise any right or remedy shall be construed as a waiver of the right or remedy or of any breach or Default by Tenant. The acceptance by Landlord of rent shall not be a (i) waiver of any preceding breach or Default by Tenant of any provision of this Lease, other than the failure of Tenant to pay the particular rent accepted, regardless of Landlord’s knowledge of the preceding

breach or Default at the time of acceptance of rent, or (ii) a waiver of Landlord’s right to exercise any remedy available to Landlord by virtue of the breach or Default. No payment by Tenant or receipt by Landlord of a lesser amount than the rent required by this Lease shall be deemed to be other than a partial payment on account of the earliest due stipulated rent, nor shall any endorsement or statement on any check or letter be deemed an accord and satisfaction and Landlord shall accept the check or payment without prejudice to Landlord’s right to recover the balance of the rent or pursue any other remedy available to it. Tenant hereby waives any right of redemption or relief from forfeiture under California Code of Civil Procedure Section 1174 or 1179, or under any successor statute, in the event this Lease is terminated by reason of any Default by Tenant. No act or thing done by Landlord or Landlord’s agents during the Term shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept a surrender shall be valid unless in writing and signed by Landlord. No employee of Landlord or of Landlord’s agents shall have any power to accept the keys to the Premises prior to the termination of this Lease, and the delivery of the keys to any employee shall not operate as a termination of the Lease or a surrender of the Premises.

(a) Any Rent due under this Lease that is not paid to Landlord within 5 days of the date when due shall bear interest at the maximum rate permitted by law from the date due until fully paid. The payment of interest shall not cure any Default by Tenant under this Lease. In addition, Tenant acknowledges that the late payment by Tenant to Landlord of rent will cause Landlord to incur costs not contemplated by this Lease, the exact amount of which will be extremely difficult and impracticable to ascertain. Those costs may include, but are not limited to, administrative, processing and accounting charges, and late charges which may be imposed on Landlord by the terms of any ground lease, mortgage or trust deed covering the Premises. Accordingly, if any rent due from Tenant shall not be received by Landlord or Landlord’s designee within 5 days after the date due, then Tenant shall pay to Landlord, in addition to the interest provided above, a late charge for each delinquent payment equal to the greater of (i) 5% of that delinquent payment or (ii) $100.00. Notwithstanding the foregoing, the late fee for the initial late payment of Basic Rent and/or Operating Expenses during each calendar year of the Term shall be waived. Acceptance of a late charge by Landlord shall not constitute a waiver of Tenant’s Default with respect to the overdue amount, nor shall it prevent Landlord from exercising any of its other rights and remedies.

14.4. RIGHT OF LANDLORD TO PERFORM. If Tenant is in Default of any of its obligations under the Lease, Landlord shall have the right to perform such obligations. Tenant shall reimburse Landlord for the cost of such performance upon demand together with an administrative charge equal to 10% of the cost of the work performed by Landlord.

14.5. DEFAULT BY LANDLORD. Landlord shall not be deemed to be in default in the performance of any obligation under this Lease unless and until it has failed to perform the obligation within 30 days after written notice by Tenant to Landlord specifying in reasonable detail the nature and extent of the failure; provided, however, that if the nature of Landlord’s obligation is such that more than 30 days are required for its performance, then Landlord shall not be deemed to be in default if it commences performance within the 30 day period and thereafter diligently pursues the cure to completion. Tenant hereby waives any right to terminate or rescind this Lease as a result of any default by Landlord hereunder or any breach by Landlord of any promise or inducement relating hereto, and Tenant agrees that its remedies shall be limited to a suit for actual damages and/or injunction and shall in no event include any consequential damages, lost profits or opportunity costs.

14.6. EXPENSES AND LEGAL FEES. Should either Landlord or Tenant bring any action in connection with this Lease, the prevailing party shall be entitled to recover as a part of the action its reasonable attorneys’ fees, and all other reasonable costs. The prevailing party for the purpose of this paragraph shall be determined by the trier of the facts.

(a) LANDLORD AND TENANT EACH ACKNOWLEDGES THAT IT IS AWARE OF AND HAS HAD THE ADVICE OF COUNSEL OF ITS CHOICE WITH RESPECT TO ITS RIGHT TO TRIAL BY JURY, AND EACH PARTY DOES HEREBY EXPRESSLY AND KNOWINGLY WAIVE AND RELEASE ALL SUCH RIGHTS TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER PARTY HERETO AGAINST THE OTHER (AND/OR AGAINST ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR SUBSIDIARY OR AFFILIATED ENTITIES) ON ANY MATTERS WHATSOEVER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS LEASE, TENANT’S USE OR OCCUPANCY OF THE PREMISES, AND/OR ANY CLAIM OF INJURY OR DAMAGE.

(b) In the event that the jury waiver provisions of Section 14.7 (a) are not enforceable under California law, then, unless otherwise agreed to by the parties, the provisions of this Section 14.7 (b) shall apply. Landlord and Tenant agree that any disputes arising in connection with this Lease (including but not limited to a determination of any and all of the issues in such dispute, whether of fact or of law) shall be resolved (and a decision shall be rendered) by way of a general reference as provided for in Part 2, Title 8, Chapter 6 (§§ 638 et. seq.) of the California Code of Civil Procedure, or any successor California statute governing resolution of disputes by a court appointed referee. Nothing within this Section 14.7 shall apply to an unlawful detainer action.

14.8 SATISFACTION OF JUDGMENT. The obligations of Landlord do not constitute the personal obligations of the individual partners, trustees, directors, officers, members or shareholders of Landlord or its constituent partners or members. Should Tenant recover a money judgment against Landlord, such judgment shall be satisfied only from the interest of Landlord in the Project and out of the rent or other income from such property receivable by Landlord or out of consideration received by Landlord from the sale or other disposition of all or any part of Landlord’s right, title or interest in the Project, and no action for any deficiency may be sought or obtained by Tenant.

15.1. HOLDING OVER. If Tenant holds over for any period after the Expiration Date (or earlier termination of the Term) without the prior written consent of Landlord, such tenancy shall constitute a tenancy at sufferance only and a Default by Tenant; such holding over with the prior written consent of Landlord shall constitute a month-to-month tenancy commencing on the 1st day following the termination of this Lease and terminating 30 days following delivery of written notice of termination by either Landlord or Tenant to the other. In either of such events, possession shall be subject to all of the terms of this Lease, except that the monthly rental shall be 150% of the total monthly rental for the month immediately preceding the date of termination, subject to Landlord’s right to modify same upon 30 days notice to Tenant. The acceptance by Landlord of monthly hold-over rental in a lesser amount shall not constitute a waiver of Landlord’s right to recover the full amount due unless otherwise agreed in writing by Landlord. If Tenant fails to surrender the Premises upon the expiration of this Lease despite demand to do so by Landlord, Tenant shall indemnify and hold Landlord harmless from all loss or liability, including without limitation, any claims made by any succeeding tenant relating to such failure to surrender. The foregoing provisions of this Section 15.1 are in addition to and do not affect Landlord’s right of re-entry or any other rights of Landlord under this Lease or at law.

15.2. SURRENDER OF PREMISES; REMOVAL OF PROPERTY. Upon the Expiration Date or upon any earlier termination of this Lease, Tenant shall quit and surrender possession of the Premises to Landlord in as good order, condition and repair as on the Commencement Date or as hereafter may be improved by Landlord or Tenant, reasonable wear and tear, casualty, condemnation and repairs which are Landlord’s obligation excepted, and shall remove all wallpapering, voice and/or data transmission cabling installed by or for Tenant and Required Removables, together with all personal property and debris, and shall perform all work required under Section 7.3 of this Lease except for any items that Landlord may by written authorization allow to remain. If Tenant shall fail to comply with the provisions of this Section 15.2, Landlord may effect the removal and/or make any repairs, and the cost to Landlord shall be additional rent payable by Tenant upon demand.

All sums payable by Tenant to Landlord shall be paid, without deduction or offset, in lawful money of the United States to Landlord at its address set forth in Item 12 of the Basic Lease Provisions, or at any other place as Landlord may designate in writing. Unless this Lease expressly provides otherwise, as for example in the payment of rent pursuant to Section 4.1, all payments shall be due and payable within 5 days after demand. All payments requiring proration shall be prorated on the basis of the number of days in the pertinent calendar month or year, as applicable. Any notice, election, demand, consent, approval or other communication to be given or other document to be delivered by either party to the other may be delivered to the other party, at the address set forth in Item 12 of the Basic Lease Provisions, by personal service, or by any courier or “overnight” express mailing service. Either party may, by written notice to the other, served in the manner provided in this Article, designate a different address. The refusal to accept delivery of a notice, or the inability to deliver the notice (whether due to a change of address for which notice was not duly given or other good reason), shall be deemed delivery and receipt of the notice as of the date of attempted delivery. If more than one person or entity is named as Tenant under this Lease, service of any notice upon any one of them shall be deemed as service upon all of them.

Tenant agrees to comply with the Rules and Regulations attached as Exhibit E, and any reasonable and nondiscriminatory amendments, modifications and/or additions as may be adopted and published by written notice to tenants by Landlord for the safety, care, security, good order, or cleanliness of the Premises, Building, Project and/or Common Areas. Landlord shall not be liable to Tenant for any violation of the Rules and Regulations or the breach of any covenant or condition in any lease or any other act or conduct by any other tenant, and the same shall not constitute a constructive eviction hereunder. One or more waivers by Landlord of any breach of the Rules and Regulations by Tenant or by any other tenant(s) shall not be a waiver of any subsequent breach of that rule or any other. Tenant’s failure to keep and observe the Rules and Regulations shall constitute a default under this Lease. In the case of any conflict between the Rules and Regulations and this Lease, this Lease shall be controlling.

The parties recognize the brokerage firms which negotiated this Lease on behalf of Landlord (the “Landlord’s Broker”) as stated in Item 10 of the Basic Lease Provisions, and that no broker has represented Tenant in connection with this Lease. Landlord shall be responsible for the payment of brokerage commissions to Landlord’s Broker. Each party warrants that it has had no dealings with any other real estate broker or agent in connection with the negotiation of this Lease, and agrees to indemnify and hold the other party harmless from any cost, expense or liability (including reasonable attorneys’ fees) for any compensation, commissions or charges claimed by any other real estate broker or agent employed or claiming to represent or to have been employed by the indemnifying party in connection with the negotiation of this Lease. The foregoing agreement shall survive the termination of this Lease.

In the event of any transfer of Landlord’s interest in the Premises (other than to a Mortgagee), provided the transferee assumes in writing the transferor’s obligations under this Lease accruing from and after the effective date of said transfer, the transferor shall be automatically relieved of all obligations on the part of Landlord accruing under this Lease from and after the date of the transfer, provided that Tenant is duly notified of the transfer. Any funds held by the transferor in which Tenant has an interest, including without limitation, the Security Deposit, shall be turned over, subject to that interest, to the transferee. No Mortgagee to which this Lease is or may be subordinate shall be responsible in connection with the Security Deposit unless the Mortgagee actually receives the Security Deposit. It is intended that the covenants and obligations contained in this Lease on the part of Landlord shall, subject to the foregoing, be binding on Landlord, its successors and assigns, only during and in respect to their respective successive periods of ownership.

20.1. NUMBER. Whenever the context of this Lease requires, the words “Landlord” and “Tenant” shall include the plural as well as the singular.

20.2. HEADINGS. The captions and headings of the articles and sections of this Lease are for convenience only, are not a part of this Lease and shall have no effect upon its construction or interpretation.

20.3. JOINT AND SEVERAL LIABILITY. If more than one person or entity is named as Tenant, the obligations imposed upon each shall be joint and several and the act of or notice from, or notice or refund to, or the signature of, any one or more of them shall be binding on all of them with respect to the tenancy of this Lease, including, but not limited to, any renewal, extension, termination or modification of this Lease.

20.4. SUCCESSORS. Subject to Sections 13.1 and 22.3 and to Articles 9 and 19 of this Lease, all rights and liabilities given to or imposed upon Landlord and Tenant shall extend to and bind their respective heirs, executors, administrators, successors and assigns. Nothing contained in this Section 20.4 is intended, or shall be construed, to grant to any person other than Landlord and Tenant and their successors and assigns any rights or remedies under this Lease.

20.5. TIME OF ESSENCE. Time is of the essence with respect to the performance of every provision of this Lease in which time of performance is a factor.

20.6. CONTROLLING LAW/VENUE. This Lease shall be governed by and interpreted in accordance with the laws of the State of California. Should any litigation be commenced between the parties in connection with this Lease, such action shall be prosecuted in the applicable State Court of California in the county in which the Building is located.

20.7. SEVERABILITY. If any term or provision of this Lease, the deletion of which would not adversely affect the receipt of any material benefit by either party or the deletion of which is consented to by the party adversely affected, shall be held invalid or unenforceable to any extent, the remainder of this Lease shall not be affected and each term and provision of this Lease shall be valid and enforceable to the fullest extent permitted by law.

20.8. WAIVER. One or more waivers by Landlord or Tenant of any breach of any term, covenant or condition contained in this Lease shall not be a waiver of any subsequent breach of the same or any other term, covenant or condition. Consent to any act by one of the parties shall not be deemed to render unnecessary the obtaining of that party’s consent to any subsequent act. No breach of this Lease shall be deemed to have been waived unless the waiver is in a writing signed by the waiving party.

20.9. INABILITY TO PERFORM. In the event that either party shall be delayed or hindered in or prevented from the performance of any work or in performing any act required under this Lease by reason of any cause beyond the reasonable control of that party, then the performance of the work or the doing of the act shall be excused for the period of the delay and the time for performance shall be extended for a period equivalent to the period of the delay. The provisions of this Section 20.9 shall not operate to excuse Tenant from the prompt payment of Rent.

20.10. ENTIRE AGREEMENT. This Lease and its exhibits and other attachments cover in full each and every agreement of every kind between the parties concerning the Premises, the Building, and the Project, and all preliminary negotiations, oral agreements, understandings and/or practices, except those contained in this Lease, are superseded and of no further effect. Tenant waives its rights to rely on any representations or promises made by Landlord or others which are not contained in this Lease. No verbal agreement or implied covenant shall be held to modify the provisions of this Lease, any statute, law, or custom to the contrary notwithstanding.

20.11. QUIET ENJOYMENT. Upon the observance and performance of all the covenants, terms and conditions on Tenant’s part to be observed and performed, and subject to the other provisions of this Lease, Tenant shall have the right of quiet enjoyment and use of the Premises for the Term without hindrance or interruption by Landlord or any other person claiming by or through Landlord.

20.12. SURVIVAL. All covenants of Landlord or Tenant which reasonably would be intended to survive the expiration or sooner termination of this Lease, including without limitation any warranty or indemnity hereunder, shall so survive and continue to be binding upon and inure to the benefit of the respective parties and their successors and assigns.

21.1. COUNTERPARTS. This Lease may be executed in one or more counterparts, each of which shall constitute an original and all of which shall be one and the same agreement.

21.2. CORPORATE AND PARTNERSHIP AUTHORITY. If Tenant is a corporation, limited liability company or partnership, Tenant represents and warrants that each individual executing this Lease on behalf of Tenant is duly authorized to execute and deliver this Lease and that this Lease is binding upon the corporation, limited liability company or partnership in accordance with its terms.

21.3. EXECUTION OF LEASE; NO OPTION OR OFFER. The submission of this Lease to Tenant shall be for examination purposes only, and shall not constitute an offer to or option for Tenant to lease the Premises. Execution of this Lease by Tenant and its return to Landlord shall not be binding upon Landlord, notwithstanding any time interval, until Landlord has in fact executed and delivered this Lease to Tenant, it being intended that this Lease shall only become effective upon execution by Landlord and delivery of a fully executed counterpart to Tenant.

21.4. RECORDING. Tenant shall not record this Lease without the prior written consent of Landlord. Tenant, upon the request of Landlord, shall execute and acknowledge a “short form” memorandum of this Lease for recording purposes.

21.5. AMENDMENTS. No amendment or mutual termination of this Lease shall be effective unless in writing signed by authorized signatories of Tenant and Landlord, or by their respective successors in interest. No actions, policies, oral or informal arrangements, business dealings or other course of conduct by or between the parties shall be deemed to modify this Lease in any respect.

21.6. ATTACHMENTS. All exhibits, riders and addenda attached to this Lease are hereby incorporated into and made a part of this Lease.

22.1. NONDISCLOSURE OF LEASE TERMS. Tenant acknowledges that the content of this Lease and any related documents are confidential information. Except to the extent disclosure is required by law, Tenant shall keep such confidential information strictly confidential and shall not disclose such confidential information to any person or entity other than Tenant’s financial, legal and space-planning consultants, and except that: (i) Tenant is required to disclose the Confidential Information in response to a subpoena or other regulatory, administrative or court order, (ii) Tenant is required to disclose the Confidential Information to, or file a copy of this Lease with, any governmental agency or any stock exchange; provided, however, that if disclosure of the Confidential Information is required by subpoena or other regulatory, administrative or court order, Tenant shall provide Landlord with as much advance notice of the possibility of such disclosure as practical so that Landlord may attempt to stop such disclosure or obtain an order concerning such disclosure. In addition, Tenant may disclose the terms of this Lease to (i) prospective assignees of this Lease and prospective subtenants under this Lease with whom Tenant is actively negotiating such an assignment or sublease, (ii) to Tenant’s attorneys, accountants and financial advisors, and (iii) in connection with any acquisition of Tenant by merger, consolidation, nonbankruptcy reorganization, or government action, a sale of substantially all of Tenant’s assets, any sale or transfer of Tenant’s capital stock or any financing by Tenant.

22.2. TENANT’S FINANCIAL STATEMENTS. The application, financial statements and tax returns, if any, submitted and certified to by Tenant as an accurate representation of its financial condition have been prepared, certified and submitted to Landlord as an inducement and consideration to Landlord to enter into this Lease. Tenant shall during the Term furnish Landlord with current annual financial statements accurately reflecting Tenant’s financial condition upon written request from Landlord within 20 days following Landlord’s request (but not more frequently than once during any calendar year); provided, however, that so long as Tenant is a publicly traded corporation on a nationally recognized stock exchange, the foregoing obligation to deliver the statements shall be waived. If delivered to Landlord marked or otherwise designate as “confidential”, Landlord agrees that it will keep the statements confidential, except that Landlord shall have the right to deliver the same to any proposed purchaser of the Building or Project, and to any encumbrancer or proposed encumbrancer of all or any portion of the Building or Project.

22.3. MORTGAGEE PROTECTION. No act or failure to act on the part of Landlord which would otherwise entitle Tenant to be relieved of its obligations hereunder or to terminate this Lease shall result in such a release or termination unless (a) Tenant has given notice by registered or certified mail to any Mortgagee of a Mortgage covering the Building whose address has been furnished to Tenant and (b) such Mortgagee is afforded a reasonable opportunity to cure the default by Landlord (which shall in no event be less than 60 days), including, if necessary to effect the cure, time to obtain possession of the Building by power of sale or judicial foreclosure provided that such foreclosure remedy is diligently pursued. Tenant shall comply with any written directions by any Mortgagee to pay Rent due hereunder directly to such Mortgagee without determining whether a default exists under such Mortgagee’s Mortgage.

22.4. SDN LIST. Tenant hereby represents and warrants that neither Tenant nor any officer, director, employee, partner, member or other principal of Tenant (collectively, “Tenant Parties”) is listed as a Specially Designated National and Blocked Person (“SDN”) on the list of such persons and entities issued by the U.S. Treasury Office of Foreign Assets Control (OFAC). In the event Tenant or any Tenant Party is or becomes listed as an SDN, Tenant shall be deemed in breach of this Lease and Landlord shall have the right to terminate this Lease immediately upon written notice to Tenant.

(a) From and after the Commencement Date, Tenant shall pay to Landlord, as additional rent, Tenant’s Share of all Operating Expenses, as defined in Section (f) below, incurred by Landlord in the operation of the Building and the Project. The term “Tenant’s Share” means 100% of the Operating Expenses determined by Landlord to benefit or relate substantially to the Building, plus that portion of any Operating Expenses reasonably determined by multiplying the cost of such item by a fraction, the numerator of which is the Floor Area and the denominator of which is the total rentable square footage, as reasonably determined from time to time by Landlord, of all or some of the buildings in the Project, for expenses reasonably determined by Landlord to benefit or relate substantially to all or some of the buildings in the Project rather than any specific building. In the event that Landlord reasonably determines that the Premises or the Building incur a non-proportional benefit from any expense, or is the non-proportional cause of any such expense, Landlord may allocate a greater percentage of such Operating Expense to the Premises or the Building. In the event that any management and/or overhead fee payable or imposed by Landlord for the management of Tenant’s Premises is calculated as a percentage of the rent payable by Tenant and other tenants of Landlord, then the full amount of such management and/or overhead fee which is attributable to the rent paid by Tenant shall be additional rent payable by Tenant, in full, provided, however, that Landlord may elect to include such full amount as part of Tenant’s Share of Operating Expenses.

(b) Commencing prior to the start of the first full “Expense Recovery Period” of the Lease (as defined in Item 7 of the Basic Lease Provisions), and prior to the start of each full or partial Expense Recovery Period thereafter, Landlord shall give Tenant a written estimate of the amount of Tenant’s Share of Operating Expenses for the applicable Expense Recovery Period. Tenant shall pay the estimated amounts to Landlord in equal monthly installments, in advance, concurrently with payments of Basic Rent. If Landlord has not furnished its written estimate for any Expense Recovery Period by the time set forth above, Tenant shall continue to pay monthly the estimated Tenant’s Share of Operating Expenses in effect during the prior Expense Recovery Period; provided that when the new estimate is delivered to Tenant, Tenant shall, at the next monthly payment date, pay any accrued estimated Tenant’s Share of Operating Expenses based upon the new estimate. Landlord may from time to time change the Expense Recovery Period to reflect a calendar year or a new fiscal year of Landlord, as applicable, in which event Tenant’s Share of Operating Expenses shall be equitably prorated for any partial year.

(c) Within 180 days after the end of each Expense Recovery Period, Landlord shall furnish to Tenant a statement (a “Reconciliation Statement”) showing in reasonable detail the actual or prorated Tenant’s Share of Operating Expenses incurred by Landlord during such Expense Recovery Period, and the parties shall within 30 days thereafter make any payment or allowance necessary to adjust Tenant’s estimated payments of Tenant’s Share of Operating Expenses, if any, to the actual Tenant’s Share of Operating Expenses as shown by the Reconciliation Statement. Any delay or failure by Landlord in delivering any Reconciliation Statement shall not constitute a waiver of Landlord’s right to require Tenant to pay Tenant’s Share of Operating Expenses pursuant hereto. Any amount due Tenant shall be credited against installments of Basic Rent and Operating Expenses next coming due, and any deficiency shall be paid by Tenant together with the next installment of Basic Rent. Should Tenant fail to object in writing to Landlord’s determination of Tenant’s Share of Operating Expenses or fail to give written notice of its intent to audit Landlord’s Operating Expenses pursuant to the provisions of the next succeeding paragraph, within 180 days following delivery of Landlord’s Reconciliation Statement, Landlord’s determination of Tenant’s Share of Operating Expenses for the applicable Expense Recovery Period shall be conclusive and binding on Tenant for all purposes and any future claims by Tenant to the contrary shall be barred.

Provided no Default has occurred and is continuing, Tenant shall have the right to cause a certified public accountant, engaged on a non-contingency fee basis, to audit Operating Expenses by inspecting Landlord’s general ledger of expenses not more than once during any Expense Recovery Period. However, to the extent that insurance premiums or any other component of Operating Expenses is determined by Landlord on the basis of an internal allocation of costs utilizing information Landlord in good faith deems proprietary, such expense component shall not be subject to audit so long as it does not exceed the amount per square foot typically imposed by landlords of other first class business parks in Santa Clara County, California. Tenant shall give notice to Landlord of Tenant’s intent to audit within one hundred eighty (180) days after Tenant’s receipt of Landlord’s expense statement which sets forth Tenant’s Share of Landlord’s actual Operating Expenses. Such audit shall be conducted at a

mutually agreeable time during normal business hours at the office of Landlord or its management agent where such accounts are maintained. If Tenant’s audit determines that actual Operating Expenses have been overstated by more than five percent (5%), then subject to Landlord’s right to review and/or contest the audit results, Landlord shall reimburse Tenant for the reasonable out-of-pocket costs of such audit. Tenant’s rent shall be appropriately adjusted to reflect any overstatement in Operating Expenses. In the event of a dispute between Landlord and Tenant regarding such audit, such dispute shall be submitted and resolved by binding arbitration pursuant to Section 6.1 of the Lease. All of the information obtained by Tenant and/or its auditor in connection with such audit, as well as any compromise, settlement, or adjustment reached between Landlord and Tenant as a result thereof, shall be held in strict confidence and, except as may be required pursuant to litigation, shall not be disclosed to any third party, directly or indirectly, by Tenant or its auditor or any of their officers, agents or employees. Landlord may require Tenant’s auditor to execute a separate confidentiality agreement affirming the foregoing as a condition precedent to any audit. In the event of a violation of this confidentiality covenant in connection with any audit, then in addition to any other legal or equitable remedy available to Landlord, Tenant shall forfeit its right to any reconciliation or cost reimbursement payment from Landlord due to said audit (and any such payment theretofore made by Landlord shall be promptly returned by Tenant), and Tenant shall have no further audit rights under this Lease. Notwithstanding the foregoing, Tenant shall have no right of audit with respect to any Expense Recovery Period unless the total Operating Expenses per square foot for such Expense Recovery Period, as set forth in Landlord’s annual expense reconciliation, exceed the total Operating Expenses per square foot during the initial Expense Recovery Period during the Term, as increased by the percentage change in the United States Department of Labor, Bureau of Labor Statistics, Consumer Price Index for ail Urban Consumers, San Francisco-Oakland-San Jose, CA Area Average, all items (1982-84 = 100) (the “Index”), which change in the Index shall be measured by comparing the Index published for January of the initial Expense Recovery Period during the Term with the Index published for January of the applicable Expense Recovery Period.

(d) Even though this Lease has terminated and the Tenant has vacated the Premises, when the final determination is made of Tenant’s Share of Operating Expenses for the Expense Recovery Period in which this Lease terminates, Tenant shall within 30 days of written notice pay the entire increase over the estimated Tenant’s Share of Operating Expenses already paid. Conversely, any overpayment by Tenant shall be rebated by Landlord to Tenant not later than 30 days after such final determination. However, in lieu thereof, Landlord may deliver a reasonable estimate of the anticipated reconciliation amount to Tenant prior to the Expiration Date of the Term, in which event the appropriate party shall fund the amount by the Expiration Date.

(e) If, at any time during any Expense Recovery Period, any one or more of the Operating Expenses are increased to a rate(s) or amount(s) in excess of the rate(s) or amount(s) used in calculating the estimated Tenant’s Share of Operating Expenses for the year, then the estimate of Tenant’s Share of Operating Expenses may be increased by written notice from Landlord for the month in which such rate(s) or amount(s) becomes effective and for all succeeding months by an amount equal to the estimated amount of Tenant’s Share of the increase. Landlord shall give Tenant written notice of the amount or estimated amount of the increase, the month in which the increase will become effective, Tenant’s Share thereof and the months for which the payments are due. Tenant shall pay the increase to Landlord as part of the Tenant’s monthly payments of estimated expenses as provided in paragraph (b) above, commencing with the month in which effective.

(f) The term “Operating Expenses” shall mean and include all Project Costs, as defined in Section (g) below, and Property Taxes, as defined in Section (h) below.

(g) The term “Project Costs” shall mean all expenses of operation, management, repair, replacement and maintenance of the Building and the Project, including without limitation all appurtenant Common Areas (as defined in Section 6.2 of the Lease), and shall include the following charges by way of illustration but not limitation: water and sewer charges; insurance premiums, deductibles, or reasonable premium equivalents or deductible equivalents should Landlord elect to self insure any risk that Landlord is authorized to insure hereunder (provided, however, that Tenant’s obligation to reimburse any such deductible or deductible equivalent shall not exceed the amount of One Hundred Thousand Dollars ($100,000.00) per occurrence for any casualty); license, permit, and inspection fees (but excluding business management and/or broker licenses); light; power; window washing; trash pickup; heating, ventilating and air conditioning; supplies; materials; equipment; tools; reasonable fees for consulting services; access control/security costs, inclusive of the reasonable cost of improvements made to enhance access control systems and procedures; costs incurred in connection with compliance with any laws or changes in laws becoming effective after the Commencement Date applicable to the Building or the Project (provided that, except for laws or changes in laws that pertain

particularly to Tenant or to Tenant’s particular use of the Premises (which shall be the sole responsibility of Tenant at its cost), to the extent such laws or change in laws require expenditures of a “capital” nature, then such “capital” expenditure shall be amortized (using a market cost of funds as reasonably determined by Landlord) over the useful life of such asset and only the amortized cost thereof shall be includable in Project Costs during the remaining Term of the Lease); the cost of any capital expenditures or replacements (other than tenant improvements for specific tenants) to the extent of the amortized amount thereof over the useful life of such capital expenditures or replacements (or, if such capital expenditures or replacements are anticipated to achieve a cost savings as to the Operating Expenses, any shorter estimated period of time over which the cost of the capital expenditures or replacements would be recovered from the estimated cost savings) calculated at a market cost of funds, all as reasonably determined by Landlord, for each year of useful life or shorter recovery period of such capital expenditure whether such capital expenditure occurs during or prior to the commencement of the Term; costs associated with the maintenance of an air conditioning, heating and ventilation service agreement, and maintenance of any communications or networked data transmission equipment, conduit, cabling, wiring and related telecommunications facilitating automation and control systems, remote telecommunication or data transmission infrastructure within the Building and/or the Project, and any other maintenance, repair and replacement costs associated with such infrastructure; labor; reasonably allocated wages and salaries, fringe benefits, and payroll taxes for administrative and other personnel directly applicable to the Building and/or Project, including both Landlord’s personnel and outside personnel; any expense incurred pursuant to Sections 6.1, 6.2, 7.2, 10.2, and Exhibits C and F of the Lease; and reasonable and market-competitive overhead and/or management fees for the professional operation of the Project. It is understood and agreed that Project Costs may include competitive charges for direct services (including, without limitation, management and/or operations services) provided by any subsidiary, division or affiliate of Landlord. Notwithstanding anything to the contrary herein, “Project Costs” shall not include and Tenant shall in no event have any obligation to perform or to pay directly, or to reimburse Landlord for, all or any portion of the following repairs, maintenance, improvements, replacements, premiums, claims, losses, fees, charges, costs and expenses (collectively, “Costs”): (i) Costs occasioned by the breach by Landlord of any of its obligations under this Lease; (ii) Costs of any renovation, improvements, painting or redecorating of any leasable space within Project not made available for Tenant’s use; (iii) Costs incurred in connection with negotiations or disputes with any other occupant of the Project; (iv) Costs incurred in connection with the presence of any Hazardous Material, except to the extent Tenant is responsible therefor pursuant to Section 5.3 of this Lease and except for Costs of any remediation of mold conditions which do not pre-date the Commencement Date; (v) costs incurred by Landlord in connection with the installation, operation, maintenance, repair, and monitoring of any systems, barriers or equipment whose primary function is the remediation, neutralization or other treatment of the Hazardous Materials described on Exhibit H attached hereto and any other cost arising from or related to the clean-up, remediation, removal, disposal, neutralization, monitoring, investigation or other treatment of or response to the Hazardous Materials described on Exhibit H attached hereto; (vi) interest, charges and fees incurred on debt incurred by Landlord; (vii) Costs occasioned by casualties or by the exercise of the power of eminent domain (as described in Sections 11.1 and 12.1 of this Lease, respectively); (viii) Costs for which Landlord is responsible as expressly provided in Section 3 of Exhibit G attached to this Lease (or elsewhere in this Lease, where such condition is set forth as Landlord’s “sole cost and expense”); (ix) Costs which could properly be capitalized under generally accepted accounting principles, consistently applied, except to the extent amortized over the useful life of the item in question as set forth above; and (x) Costs occasioned by the violation of any law by Landlord, its authorized agents, employees or contractors.

(h) The term “Property Taxes” as used herein shall include any form of federal, state, county or local government or municipal taxes, fees, charges or other impositions of every kind (whether general, special, ordinary or extraordinary) related to the ownership, leasing or operation of the Premises, Building or Project, including without limitation, the following: (i) all real estate taxes or personal property taxes levied against the Premises, the Building or Project, as such property taxes may be reassessed from time to time; and (ii) other taxes, charges and assessments which are levied with respect to this Lease or to the Building and/or the Project, and any improvements, fixtures and equipment and other property of Landlord located in the Building and/or the Project, (iii) all assessments and fees for public improvements, services, and facilities and impacts thereon, including without limitation arising out of any Community Facilities Districts, “Mello Roos” districts, similar assessment districts, and any traffic impact mitigation assessments or fees; (iv) any tax, surcharge or assessment which shall be levied in addition to or in lieu of real estate or personal property taxes, and (v) taxes based on the receipt of rent (including gross receipts or sales taxes applicable to the receipt of rent), and (vi) costs and expenses incurred in contesting the amount or validity of any Property Tax by appropriate proceedings. Notwithstanding the foregoing, general net income or franchise taxes imposed against Landlord shall be excluded, and “Property Taxes” shall not include and Tenant shall not be required to pay any portion of any tax or assessment expense or any increase therein (a) in

excess of the amount which would be payable if such tax or assessment expense were paid in installments over the longest permitted term; (b) imposed on land and improvements other than the Building or the Project; or (c) attributable to Landlord’s inheritance, gift or estate taxes.

Tenant shall be responsible for and shall pay promptly, directly to the appropriate supplier, all charges for electricity metered to the Premises, telephone, telecommunications service, janitorial service, interior landscape maintenance and all other utilities, materials and services furnished directly to Tenant or the Premises or used by Tenant in, on or about the Premises during the Term, together with any taxes thereon. Landlord shall make a reasonable determination of Tenant’s proportionate share of the cost of water, gas, sewer, refuse pickup and any other utilities and services that are not separately metered to the Premises and services, and Tenant shall pay such amount to Landlord, as an item of additional rent, within 10 days after delivery of Landlord’s statement or invoice therefor. Alternatively, Landlord may elect to include such cost in the definition of Project Costs in which event Tenant shall pay Tenant’s proportionate share of such costs in the manner set forth in Section 4.2.

The following requirements for Tenant’s insurance shall be in effect during the Term, and Tenant shall also cause any subtenant to comply with the requirements. Landlord reserves the right to adopt reasonable nondiscriminatory modifications and additions to these requirements (which Landlord shall use its good faith efforts to adopt for all tenants of the Project).

1. Tenant shall maintain, at its sole cost and expense, during the entire Term: (i) commercial general liability insurance with respect to the Premises and the operations of Tenant in, on or about the Premises, including but not limited to coverage for personal injury, broad form property damage, fire legal liability, products liability (if a product is sold from the Premises), which policy(ies) shall be written on an “occurrence” basis and for not less than $1,000,000 per occurrence and $2,000,000 in the aggregate for bodily injury, death, and property damage liability; (ii) workers’ compensation insurance coverage as required by law, together with employers’ liability insurance coverage of at least $1,000,000; (iii) with respect to Tenant Improvements and Alterations constructed by Tenant under this Lease, builder’s risk insurance, in an amount equal to the replacement cost of the work; and (iv) insurance against fire, vandalism, malicious mischief and such other additional perils as may be included in a standard “special form” policy, insuring all Tenant Installations, the Tenant Improvements and trade fixtures, furnishings, equipment and items of personal property in the Premises, in an amount equal to not less than 90% of their actual replacement cost (with replacement cost endorsement), which policy shall also include business interruption coverage in an amount sufficient to cover 1 year of loss. In no event shall the limits of any policy be considered as limiting the liability of Tenant under this Lease.

2. All policies of insurance required to be carried by Tenant pursuant to this Exhibit D shall be written by insurance companies authorized to do business in the State of California and with a general policyholder rating of not less than “A-” and financial rating of not less than “VIII” in the most current Best’s Insurance Report. The deductible or other retained limit under any policy carried by Tenant shall be commercially reasonable, and Tenant shall be responsible for payment of such deductible or retained limit with waiver of subrogation as to property insurance in favor of Landlord. Any insurance required of Tenant may be furnished by Tenant under any blanket policy carried by it or under a separate policy. A certificate of insurance, certifying that the policy has been issued, shall be delivered to Landlord prior to the date Tenant is given the right of possession of the Premises. Proper evidence of the renewal of any insurance coverage shall also be delivered to Landlord not less than three (3) days after the expiration of the coverage. In the event of a loss covered by any policy under which Landlord is an additional insured, Landlord shall be entitled to review a copy of such policy.

3. Tenant’s commercial general liability insurance shall contain a provision that the policy shall be primary to and noncontributory with any policies carried by Landlord, together with a provision including Landlord and any other parties in interest designated by Landlord as additional insureds. Tenant’s policies described in Subsections 1 (ii), (iii) and (iv) above shall each contain a waiver by the insurer of any right to subrogation against Landlord, its agents, employees, contractors and representatives. Tenant also waives its right of recovery for any deductible or retained limit under the property insurance policies enumerated above. All of Tenant’s policies shall contain a provision that the insurer will not cancel or reduce the coverage provided by the policy without first giving Landlord 30 days prior written notice. Tenant shall also name Landlord as an additional insured on any excess or umbrella liability insurance policy carried by Tenant to the extent required under this Lease.

1.1 Landlord shall use commercially reasonable efforts to construct on a continuous basis in accordance with industry custom and practice, at its sole cost and expense, and without deduction from the “Landlord Contribution” (as hereinafter defined), the base shell, and core of the Building, which base, shell and core shall be constructed in compliance with all applicable laws (collectively, the “Base, Shell and Core” and/or “Base Building”), and substantially in accordance with (i) the plans and specifications prepared by LPA, Inc. and referenced in Schedule 1 attached hereto (the “Base Building Plans”), and (ii) the “Outline Specifications- Shell Building Improvements” set forth in Schedule 4 attached hereto (provided that to the extent of any inconsistency, the Base Building Plans shall control). Landlord hereby reserves the right to modify the Base Building Plans without the approval of Tenant, provided that such modifications (A) are required to comply with applicable laws, and (B) will not materially and adversely affect Tenant’s permitted use of the Premises. Any other modifications of the Base Building Plans shall require the prior approval of Tenant, which approval shall not be unreasonably withheld within 2 business days following Tenant’s receipt of Landlord’s request for approval of such modifications.

1.2 Landlord and Tenant hereby acknowledge and agree that Landlord designed the Base Building to be compliant with LEED Silver requirements. Landlord shall submit all required documents to the U.S. Green Building Council and shall use all commercially reasonable efforts in an attempt to achieve such LEED Silver certification.

2.1 Tenant and Landlord shall approve, within the time period set forth below, working drawings and specifications (the “Working Drawings and Specifications”) for the construction of certain Tenant Improvements in the Premises (the “Tenant Improvements”), prepared by Landlord’s architect and engineers. To the extent applicable, the Working Drawing and Specification shall include Landlord’s building standard tenant improvements, materials and specifications for the Project as set forth in the “Outline Specifications- Tenant Improvements” set forth in the attached Schedule 4 (“Building Standard Improvements”), except for changes and additions specifically requested by Tenant and reasonably approved by Landlord in writing (any such addition or variation from the Standard Improvements shall be referred to herein as a (“Non-Standard Improvement”). All Tenant requests for Non-Standard Improvements must be in writing and shall provide sufficient specifications and details for Landlord to reasonably evaluate impacts upon the Working Drawings and Specifications and Final Cost Estimate. Tenant shall approve or provide suggested revisions to the Working Drawings and Specifications by signing copies of each or specifying in reasonable detail any suggested revisions thereto as hereinabove provided, and delivering each to Landlord within 5 business days of receipt thereof by Tenant. Landlord shall in good faith modify the Working Drawings and Specifications to incorporate Tenant’s suggested revisions in a mutually satisfactory manner. Notwithstanding the foregoing, Tenant shall approve in all respects, the Working Drawings and Specifications (as same may have been modified as herein provided to incorporate Tenant’s suggested revisions) not later than March 1, 2013 (the “Plan Approval Date”), it being understood that Tenant’s failure to do so, except to the extent such failure is caused by Landlord’s failure to timely perform as provided in the foregoing and subject to the provisions of Section 2.5 below, shall constitute a “Tenant Delay” (as defined below).

2.2 In the event that Tenant subsequently requests in writing a revision to the Working Drawings and Specifications approved by the parties pursuant to Section 2.1 above (“Change”), and Landlord so approves such Change as provided in the Section next below, Landlord shall advise Tenant by written order (a “Change Order”) as soon as is practical of any net cost increase in the Completion Cost above the Final Cost Estimate (taking into account any cost savings attributable to such Change Order together with previous Change Orders) and the amount of any Tenant Delay such Change would cause. Tenant shall approve or disapprove such Change Order, if any, in writing within 2 business days following Tenant’s receipt of such Change Order. If Tenant disapproves any such Change Order, Tenant shall nonetheless be responsible for the reasonable architectural and/or planning fees incurred in preparing such Change Order. Landlord shall have no obligation to interrupt or modify the Tenant Improvement Work pending Tenant’s approval of a Change Order, but if Tenant fails to timely approve a change order, Landlord may (but shall not be required to)

suspend the applicable Tenant Improvement Work, in which event, subject to the provisions of Section 2.5 below, any related critical path delays because of such suspension shall constitute Tenant Delays hereunder. Except for revisions required by code or other applicable laws which do not materially and adversely affect Tenant’s permitted use of the Premises or materially increase Tenant’s Contribution, in no event shall Landlord have the right to make any revisions to the Working Drawings and Specifications without Tenant’s prior written consent, which consent shall not be unreasonably withheld or delayed.

2.3 Landlord agrees that it shall not unreasonably withhold its consent to Tenant’s requested Changes, provided that such consent may be withheld in any event if the requested Change: (i) materially adversely affects the structure of the Building, (ii) materially adversely affects the electrical, mechanical, plumbing, life safety, sprinkler, HVAC or other systems of the Building, (iii) affects the exterior appearance of the Building or the exterior areas of the Project, (iv) does not comply with all applicable laws, (v) adversely affects the configuration of tenant spaces or the core spaces throughout the Building in the following respects: non-continuous ceiling grid, inconsistency of lighting fixtures, walls penetrating the ceiling grid, significantly non-rectangular or odd-sized offices (provided that minor variations in shape or size shall not be considered a Design Problem), or (vi) results in inconsistency of the quality, materials or finishes within the Building as to equivalently improved portions of the Premises (collectively, a “Design Problem”).

2.4 McLarney Construction, or another general contractor selected by Landlord, shall construct the Tenant Improvements under contract to Landlord. Promptly following the approval of the Working Drawings and Specifications by the parties pursuant to Section 2.1 above, Landlord shall cause its general contractor to submit the major subtrade work, including the HVAC, electrical and plumbing subtrade work (the “MEP Work”), to a competitive bidding process involving at least 3 licensed and reputable subcontractors. Not later than March 7, 2013, Landlord shall submit the final pricing for the MEP Work (including copies of the applicable competitive bid responses, if requested by Tenant) to Tenant for its reasonable approval. Landlord shall in good faith modify the MEP Work to incorporate Tenant’s suggested revisions in a mutually satisfactory manner, but Tenant shall finally approve in all respects the final pricing for the MEP Work not later than the later to occur of (i) March 12, 2013, or (ii) 5 business days from the receipt of the final pricing for the MEP Work from Landlord (the “MEP Approval Date”) . Not later than March 21, 2013, Landlord shall submit the final pricing for the remainder of the Tenant Improvement Work (the “Remainder Work”) (including copies of the applicable competitive bid responses, if requested by Tenant) to Tenant for its reasonable approval. Landlord shall in good faith modify the Remainder Work to incorporate Tenant’s suggested revisions in a mutually satisfactory manner, but Tenant’s shall finally approved in all respects the final pricing for the Remainder Work not later than the later to occur (a) March 26, 2013, or (b) 5 business days of receipt of the final pricing for the Remainder Work from Landlord (the “Remainder Work Approval Date”). The pricing of the MEP Work and the Remainder Work so approved by Tenant is herein collectively referred to as the “Final Cost Estimate”.

2.5 Notwithstanding any provision in the Lease to the contrary, and not by way of limitation of any other rights or remedies of Landlord, if Tenant fails to comply with any of the time periods specified in this Work Letter, fails otherwise to approve or reasonably disapprove any submittal within the time period specified herein for such response (or if no time period is so specified, within 5 business days following Tenant’s receipt thereof), fails to approve in writing the Working Drawings and Specifications by the Plan Approval Date, fails to timely deliver payment of any net increased costs specified in a Change Order in accordance with Section 2.2 above, requests any Changes and thereafter accepts a Change Order containing Landlord’s good faith estimate of resulting Tenant Delay, fails to approve the final pricing of the MEP Work by the MEP Work Approval Date, fails to approve the final pricing of the Remainder Work by the Remainder Work Approval Date, or otherwise actually delays in any manner for more than one (1) business day following written or oral notification thereof the completion of the Tenant Improvements (including without limitation by specifying materials that are not readily available) or the issuance of an occupancy certificate beyond the Estimated Commencement Date, and such delay would not have occurred but for Tenant’s actions or failure to act (any of the foregoing being referred to in this Lease as a “Tenant Delay”), then, subject to and as provided in Section 3.2 of the Lease, the date Tenant otherwise would commence the payment of rent under the Lease shall be advanced by the number of days that Landlord reasonably determines that it was actually delayed in delivering the Premises to Tenant following the Estimated Commencement Date due to such Tenant Delay. Any Change Order delivered by Landlord shall include a good faith estimate of the amount of any Tenant Delay and a binding estimate of the net cost increase above the Final Cost Estimate (taking into account any cost savings attributable to such Change Order together with previous Change Orders). Promptly upon Landlord’s realization that the actual amount of Tenant Delay due to Change Order will exceed the amount of delay in Landlord’s good faith estimate, landlord shall advise Tenant orally or in writing of the additional amount of delay Landlord estimates in its good faith will result therefrom. Should Landlord determine that the Commencement Date should be advanced in accordance with the foregoing, it shall so notify Tenant in writing. Landlord’s determination shall be conclusive unless Tenant notifies Landlord in writing, within five (5) business days thereafter, of Tenant’s election to contest same by arbitration pursuant to Section 4 below.

2.6 All of the Tenant Improvements shall become the property of Landlord and shall be surrendered with the Premises at the expiration or sooner termination of this Lease. Notwithstanding the foregoing, Landlord shall have the right, by notice to Tenant given prior to Tenant’s approval of the Working Drawings and Specifications and at the time of Landlord’s approval of any Change, to require Tenant to remove all or any of the Tenant Improvements approved in the Working Drawings and Specifications or by way of such Change, to repair any damage to the Premises arising from such removal, and to replace any Non-Standard Improvements so approved with the applicable Building Standard Improvement, provided that such right may only be exercised by Landlord with respect to Tenant Improvements (i) that constitute a Design Problem, or (ii) that constitute the substitution of Non-Standard Improvements for Building Standard Improvements. Any such removals, repairs and replacements by Tenant shall be completed by the Expiration

Date or sooner termination of this Lease. Notwithstanding the foregoing: (A) a reasonably customary cafeteria area shall not be subject to removal as provided in the foregoing, provided that the location and size of such cafeteria are approved by Landlord as part of the Working Drawings and Specifications, and (B) Tenant’s obligations with respect to the restoration of its data center shall be limited to removing its equipment, including the APC Infrastructure in-row cooling and in-row power distribution units (which equipment and units shall be Tenant’s property) such that the data center will be returned in vacant condition. Landlord expressly agrees that Tenant shall not be required to remove or restore the tile flooring in the data room, the chilled water coolers on the roof installed to serve the data center and associated piping required to serve the data center or the main power feed to the data center, all of which shall be the property of Landlord.

2.7 Landlord shall permit Tenant and its agents to enter the Premises 30 days prior to the Commencement Date of the Lease in order that Tenant may install its cabling and related communication equipment and other personal property through Tenant’s own contractors prior to the Commencement Date. Any such work shall be subject to Landlord’s prior written approval, and shall be performed in a manner and upon terms and conditions and at times satisfactory to Landlord’s representative. The foregoing license to enter the Premises prior to the Commencement Date is, however, conditioned upon Tenant’s contractors and their subcontractors and employees working in harmony and not interfering with the work being performed by Landlord. If at any time Landlord determines that such entry shall cause disharmony or interfere with the work being performed by Landlord, this license may be withdrawn by Landlord upon 24-hours written notice to Tenant. That license is further conditioned upon the compliance by Tenant’s contractors with all requirements imposed by Landlord on third party contractors, including without limitation the maintenance by Tenant and its contractors and subcontractors of workers’ compensation and public liability and property damage insurance in amounts and with companies and on forms satisfactory to Landlord, with certificates of such insurance being furnished to Landlord prior to proceeding with any such entry. The entry shall be deemed to be under all of the provisions of the Lease except as to the covenants to pay rent. Landlord shall not be liable in any way for any injury, loss or damage which may occur to any such work being performed by Tenant, the same being solely at Tenant’s risk. In no event shall the failure of Tenant’s contractors to complete any work in the Premises extend the Commencement Date of this Lease.

2.8 Tenant hereby designates Andreas Bechtolsheim (“Tenant’s Construction Representative”), Telephone No. (408) 547-5600, as its representative, agent and attorney-in-fact for all matters related to the Tenant Improvement Work, including but not by way of limitation, for purposes of receiving notices, approving submittals and issuing requests for Changes, and Landlord shall be entitled to rely upon authorizations and directives of such person(s) as if given directly by Tenant. The foregoing authorization is intended to provide assurance to Landlord that it may rely upon the directives and decision making of the Tenant’s Construction Representative with respect to the Tenant Improvement Work and is not intended to limit or reduce Landlord’s right to reasonably rely upon any decisions or directives given by other officers or representatives of Tenant. Tenant may amend the designation of its Tenant’s Construction Representative(s) at any time upon delivery of written notice to Landlord.

2.9 Notwithstanding anything to the contrary in the Lease or this Work Letter, Tenant’s acceptance of the Premises shall not be deemed a waiver of Tenant’s right to require Landlord to cause its contractor to correct any defects in the Base Building or the Tenant Improvements identified by Tenant, in writing, within twelve (12) months after the Commencement Date. Landlord shall promptly repair or cause contractor to repair all such defects, at no cost to Tenant.

3.1 Landlord shall complete, or cause to be completed, the Tenant Improvements, at the construction cost shown in the Final Cost Estimate (subject to increases for Landlord approved Changes to be paid by Tenant as set forth in this Work Letter), in accordance with final Working Drawings and Specifications approved by both Landlord and Tenant. The Tenant Improvements shall be constructed by Landlord in accordance with all rules, regulations, codes, ordinances, statutes, and laws of any governmental or quasi-governmental authority in effect as of the date of the issuance of the applicable building permit(s) therefor, and in a good and workman-like manner using material and equipment of new and otherwise of good quality. Landlord shall obtain standard warranties on the “supplemental” HVAC units installed as part of the Tenant Improvements and for other elements of the Tenant Improvements that Tenant is responsible for maintaining under the Lease and shall assign to Tenant, or otherwise cooperate to make available to Tenant the benefit of, all such warranties.

3.2 Landlord shall pay up to $7,480,400.00, based on $50.00 per rentable square foot of the Premises (“Landlord’s Maximum Contribution”), of the final “Completion Cost” (as defined below). Tenant acknowledges that the Landlord’s Maximum Contribution is intended only as the maximum amount Landlord will pay toward any of the Tenant Improvements described in the approved Working Drawings and Specifications (as same may be modified pursuant to a Change Order or as otherwise provided in Section 2.4 above), including but not limited to, any specialized pipe installations, but excluding alterations not included in the Working Drawings or Specifications (as same may be modified pursuant to a Change Order or as otherwise provided in Section 2.4 above). In the event the sum of the cost of the Completion Cost of the Tenant Improvement Work is less than the Landlord’s Maximum Contribution, Landlord’s actual contribution toward the Completion Cost (“Landlord’s Contribution”) shall equal such lesser amount, and Tenant shall have no right to receive any credit, refund or allowance of any kind for any unused portion of the Landlord’s Maximum Contribution nor shall Tenant be allowed to make revisions to an approved Preliminary Plan,

Working Drawings and Specifications or request a Change in an effort to apply any unused portion of Landlord’s Maximum Contribution.

3.3 Tenant shall pay the difference between Final Cost Estimate and Landlord’s Maximum Contribution, if any, plus any costs due to Tenant Delays as specified in this Work Letter and any net increases above the Final Cost Estimate as set forth in approved Change Orders, to the extent such Tenant Delay costs or Change Order costs exceed the Landlord’s Maximum Contribution. The amounts to be paid by Tenant for the Tenant Improvements pursuant to this Section 3.3 are sometimes cumulatively referred to herein as the “Tenant’s Contribution”. Notwithstanding anything to the contrary herein, in no event shall Tenant’s Contribution exceed the sum of (i) the Final Cost Estimate and (ii) any net increases above the Final Cost Estimate as set forth in approved Change Orders or due to Tenant Delays, subject to Section 2.7 above. Tenant shall pay the Tenant’s Contribution, if any, within thirty (30) days of (i) the determination of the Final Cost Estimate, and (ii) the determination of any increases caused by a Tenant Delay or Change Order, pursuant to the provisions of this Work Letter.

3.4 The “Completion Cost” shall mean all costs of Landlord in completing the Tenant Improvements in accordance with the approved Working Drawings and Specifications and with any approved Changes thereto, including but not limited to the following costs: (i) payments made to architects, engineers, contractors, subcontractors and other third party consultants in the performance of the work, (ii) salaries and fringe benefits of persons, if any, in the direct employ of Landlord performing any part of the construction work, (iii) permit fees and other sums paid to governmental agencies, and (iv) permit fees and other sums paid to governmental agencies, (v) costs of all materials incorporated into the work or used in connection with the work, and (vi) costs of design and structural upgrades to the Building required for the Tenant’s data center, including the costs of the supporting HVAC units, power facilities and water coolers. The Completion Cost shall also include an administrative/supervision fee to be paid to Landlord or to Landlord’s management agent in the amount of two (2) percent (2%) of the Landlord’s Contribution funded by Landlord. Unless expressly authorized in writing by Landlord, the Completion Cost shall not include (and no portion of the Landlord’s Contribution shall be paid for) (i) any costs incurred by Tenant, including without limitation, any costs for space planners, managers, advisors or consultants retained by Tenant in connection with the Tenant Improvements (which shall be the sole responsibility of Tenant), or (ii) the following costs (which shall be the sole responsibility of Landlord): (a) costs for improvements which are not shown on or described in the Working Drawings and Specifications (as same may be modified pursuant to a Change Order or as otherwise provided in Section 2.4 above), unless otherwise approved by Tenant, which approval shall not be unreasonably withheld; (b) costs incurred due to the presence of Hazardous Materials in the Project or the surrounding area; (c) attorneys’ fees incurred in connection with negotiation of construction contracts, and attorneys’ fees, experts’ fees and other costs in connection with disputes with third parties; (d) interest and other costs of financing construction costs; (e) costs to bring the Premises, the Building or the Common Areas into compliance with applicable laws and restrictions in the event of Landlord’s failure to construct either the Base Building or the Tenant Improvements in accordance with same; or (f) construction management, profit and overhead charges payable to Landlord, except for the administrative/supervision fee provided in Section 3.4 above.

3.5 Prior to start of construction of the Tenant Improvements, Tenant shall pay to Landlord in full the amount of the Tenant’s Contribution set forth in the approved Final Cost Estimate. The balance of any sums not otherwise paid by Tenant shall be due and payable on or before the Commencement Date of this Lease. If Tenant defaults beyond applicable notice and cure periods in the payment of any sums due under this Work Letter, Landlord shall (in addition to all other remedies) have the same rights as in the case of Tenant’s failure to pay rent under the Lease, including, without limitation, the right to terminate this Lease and recover damages from Tenant and/or to charge a late payment fee and to collect interest on delinquent payments, and Landlord may (but shall not be required to) suspend the Tenant Improvement Work following such default, in which event any delays because of such suspension shall constitute Tenant Delays hereunder.

4.1 All claims or disputes between Landlord and Tenant arising out of, or relating to, this Work Letter shall be decided by the JAMS/ENDISPUTE (“JAMS”), or its successor, with such arbitration to be held in Santa Clara County, California, unless the parties mutually agree otherwise. Within 10 business days following submission to JAMS, JAMS shall designate three arbitrators and each party may, within 5 business days thereafter, veto one of the three persons so designated. If two different designated arbitrators have been vetoed, the third arbitrator shall hear and decide the matter. If less than 2 arbitrators are timely vetoed, JAMS shall select a single arbitrator from the non-vetoed arbitrators originally designated by JAMS, who shall hear and decide the matter. Any arbitration pursuant to this section shall be decided within 30 days of submission to JAMS. The decision of the arbitrator shall be final and binding on the parties. In no event shall the arbitrator be empowered or authorized to award consequential or punitive damages (including any award for lost profit or opportunity costs or loss or interruption of business or income). All costs associated with the arbitration shall be awarded to the prevailing party as determined by the arbitrator.

4.2 Notice of the demand for arbitration by either party to the Work Letter shall be filed in writing with the other party to the Work Letter and with JAMS and shall be made within a reasonable time after the dispute has arisen. The award rendered by the arbitrator shall be final, and judgment may be entered upon it in accordance with applicable law in any court having jurisdiction thereof. Except by written consent of the

person or entity sought to be joined, no arbitration arising out of or relating to this Work Letter shall include, by consolidation, joinder or in any other manner, any person or entity not a party to the Work Letter unless (1) such person or entity is substantially involved in a common question of fact or law, (2) the presence of such person or entity is required if complete relief is to be accorded in the arbitration, or (3) the interest or responsibility of such person or entity in the matter is not insubstantial.

4.3 The agreement herein among the parties to arbitrate shall be specifically enforceable under prevailing law. The agreement to arbitrate hereunder shall apply only to disputes arising out of, or relating to, this Work Letter, and shall not apply to other matters of dispute under the Lease except as may be expressly provided in the Lease.
