ARTICLE 2. PREMISES

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 are located in 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”). Landlord and Tenant stipulate and agree that the Floor Area of Premises set forth in Item 8 of the Basic Lease Provisions is correct.

2.2. ACCEPTANCE OF PREMISES. 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, except as set forth in this Lease. 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. The taking of possession or use of the Premises by Tenant for any purpose other than construction shall conclusively establish that the Premises and the Building were in satisfactory condition and in conformity with the provisions of this Lease in all respects. Nothing contained in this Section 2.2 shall affect the commencement of the Term or the obligation of Tenant to pay rent.

2.3. GOOD WORKING ORDER WARRANTY. Landlord warrants to Tenant that the roof, doors, fire sprinkler system, plumbing, lighting, heating, ventilation and air conditioning systems and electrical systems serving the Premises shall be in good operating condition as of the day the Premises are delivered to Tenant. Provided that Tenant shall notify Landlord of a non-compliance with the foregoing warranty not later than 30 days following the date Landlord delivers possession of the Premises to Tenant pursuant to Section 1 of Exhibit G, then Landlord shall, except as otherwise provided in this Lease, promptly after receipt of written notice from Tenant setting forth the nature and extent of such noncompliance, rectify same at Landlord’s sole cost and expense (and not as a Project Cost).

ARTICLE 3. TERM

3.1. GENERAL. The term of this Lease (“Term”) shall commence on the date as set forth in Item 4 of the Basic Lease Provisions (“Commencement Date”) and shall end upon the expiration of the period set forth in Item 5 of the Basic Lease Provisions (“Expiration Date”).

3.2. DELAY IN POSSESSION. If Landlord, for any reason whatsoever, cannot deliver possession of the Premises to Tenant on or before the Commencement Date, 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 Landlord delivers possession of the Premises to Tenant unless such failure or inability to deliver possession of the Premises to Tenant is attributable to any action or inaction by ▇▇▇▇▇▇.

ARTICLE 4. RENT AND OPERATING EXPENSES

4.1. BASIC RENT. From and after the Commencement Date, Tenant shall pay to Landlord without deduction or offset, except as expressly provided herein, 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, and 1 month’s estimated Tenant’s Share of Operating Expenses shall be delivered to Landlord concurrently with ▇▇▇▇▇▇’s execution of this Lease.

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

4.3. SECURITY DEPOSIT. Concurrently with Tenant’s delivery of this Lease, Tenant shall deposit with Landlord the sum, if any, stated in Item 9 of the Basic Lease Provisions (the “Security Deposit”), to be held by Landlord as security for the full and faithful performance of Tenant’s obligations under this Lease, to pay any rental sums, including without limitation such additional rent as may be owing under any provision hereof, and to maintain the Premises as required by this Lease. Upon any Default by Tenant, Landlord may apply all or part of the Security Deposit as full or partial compensation. If any portion of the Security Deposit is so applied, Tenant shall within 5 days after written demand by Landlord deposit cash with Landlord in an amount sufficient to restore the Security Deposit to its original amount. Landlord shall not be required to keep the Security Deposit separate from its general funds, and Tenant shall not be entitled to interest on the Security Deposit. In no event may Tenant utilize all or any portion of the Security Deposit as a payment toward any Rent due under this Lease. Any unapplied balance of the Security Deposit shall be returned to Tenant or, at Landlord’s option, to the last assignee of Tenant’s interest in this Lease within 30 days following the termination of this Lease and ▇▇▇▇▇▇’s vacation of the Premises. Tenant hereby waives the provisions of Section 1950.7 of the California Civil Code, or any similar or successor laws now or hereafter in effect.

ARTICLE 5. USES

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. 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 in the Premises or the Project. Tenant shall comply at its expense with all present and future laws, ordinances and requirements of all governmental

3

authorities that pertain to Tenant or its use of the Premises, and with all energy usage reporting requirements of Landlord. Pursuant to California Civil Code § 1938, Landlord hereby states that the Premises have not undergone inspection by a Certified Access Specialist (CASp) (defined in California Civil Code § 55.52(a)(3)). Pursuant to Section 1938 of the California Civil Code, Landlord hereby provides the following notification to Tenant: “A Certified Access Specialist (CASp) can inspect the subject premises and determine whether the subject premises comply with all of the applicable construction-related accessibility standards under state law. Although state law does not require a CASp inspection of the subject premises, the commercial property owner or lessor may not prohibit the lessee or tenant from obtaining a CASp inspection of the subject premises for the occupancy or potential occupancy of the lessee or tenant, if requested by the lessee or tenant. The parties shall mutually agree on the arrangements for the time and manner of the CASp inspection, the payment of the fee for the CASp inspection, and the cost of making any repairs necessary to correct violations of construction related accessibility standards within the premises.” Landlord shall correct, repair and/or replace any noncompliance of the Building and/or the Common Areas with all building permits and codes in effect and applicable as of the execution of this Lease, including without limitation, the provisions of Title III of the Americans With Disabilities Act (“ADA”). Said costs of compliance shall be Landlord’s sole cost and expense and shall not be part of Project Costs. Landlord shall correct, repair or replace any non-compliance of the Building and the Common Areas with any revisions or amendments to applicable building codes, including the ADA, becoming effective after the execution of this Lease, provided that the amortized cost of such repairs or replacements (amortized over the useful life thereof) shall be included as Project Costs payable by Tenant. All other ADA compliance issues which pertain to the Premises, including without limitation, in connection with Tenant’s construction of any Alterations or other improvements in the Premises (and any resulting ADA compliance requirements in the Common Areas if Landlord shall consent to same as more particularly provided in Section 7.3 of this Lease) and the operation of Tenant’s business and employment practices in the Premises, shall be the responsibility of Tenant at its sole cost and expense. The repairs, corrections or replacements required of Landlord or of Tenant under the foregoing provisions of this Section 5.1 shall be made promptly following notice of noncompliance from any applicable governmental agency.

5.2. SIGNS. Landlord shall affix and maintain a sign (restricted solely to Tenant’s name/logo as set forth herein or such other name as Landlord may consent to in writing) adjacent to the entry door of the Premises, together with a listing for Tenant’s name as set forth herein in the lobby directory of the Building. Tenant shall not place or allow to be placed any other sign, decoration or advertising matter of any kind that is visible from the exterior of the Premises.

5.3. HAZARDOUS MATERIALS.

(a) For purposes of this Lease, the term “Hazardous Materials” means (i) any “hazardous material” as defined in Section 25501(n) 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 permit any Hazardous Materials to be brought upon, stored, used, generated, released or disposed of 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 reasonable discretion in accordance with this Section 5.3. 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 kind and content listed on 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 reasonable discretion, place such conditions as Landlord deems appropriate with respect to Tenant’s use, storage and/or disposal of any Hazardous Materials requiring Landlord’s consent. 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 ▇▇▇▇▇▇ 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, ▇▇▇▇▇▇ 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 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 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 ▇▇▇▇▇▇’s business in connection therewith, but shall not be liable for any such interference. In addition, Landlord, at ▇▇▇▇▇▇’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 presence of any Hazardous Materials on, under, from or about the Premises or the Project caused or 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 by Landlord to to the “Required Condition” (as hereinafter defined) 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 used herein, “Required Condition” shall mean returning the Premises and the Project and any other directly affected real or personal property owned by Landlord to a condition that is required by applicable federal, state or local law, regulation or order, including without limitation, performing any required cleanup, remediation, removal, disposal, neutralization or other treatment of Hazardous materials. 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 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, ▇▇▇▇▇▇▇▇’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 acceptable to Landlord) Landlord and any successors to all or any portion of Landlord’s interest in the Premises and the Project and any other real or personal property owned by Landlord from and against any and all liabilities, losses, damages, diminution in value, judgments, fines, demands, claims, recoveries, deficiencies, costs and expenses (including without limitation 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 and any other real or personal property owned by Landlord caused or 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 and any other real or personal property owned by Landlord, 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 or its agents, employees, contractors, licensees, subtenants or invitees may have caused or permitted the release of any Hazardous Materials on, under, from or about the Premises, the Building or the Project or any other real or personal property owned by Landlord, Tenant shall, at ▇▇▇▇▇▇▇▇’s request, immediately prepare and submit to Landlord a comprehensive plan, subject to Landlord’s reasonable approval, specifying the actions to be taken by Tenant to return the Premises, the Building or the Project or any other real or personal property owned by Landlord to the Required Condition. 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 Tenant proves were not caused or permitted by Tenant, its agents, employees, contractors, licensees, subtenants or invitees. Notwithstanding the preceding two sentences, ▇▇▇▇▇▇ 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 ▇▇▇▇▇▇’s attention. Tenant hereby acknowledges that this disclosure satisfies any obligation of Landlord to Tenant pursuant to California Health & Safety Code Section 25359.7, or any amendment or substitute thereto or any other disclosure obligations of Landlord.

ARTICLE 6. LANDLORD SERVICES

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’s failure to furnish, or any interruption, diminishment or termination of, services due to the application of laws, the failure of any equipment, the performance of repairs, improvements or alterations, utility

5

interruptions or the occurrence of an event of force majeure (defined in Section 20.7) shall not render Landlord liable to Tenant, constitute a constructive eviction of Tenant, give rise to an abatement of Rent, nor relieve Tenant from the obligation to fulfill any covenant or agreement. However, if the Premises, or a material portion of the Premises, are made untenantable for a period in excess of 5 consecutive business days as a result of a service interruption that is reasonably within the control of Landlord to correct and through no fault of Tenant and for reasons other than as contemplated in Article 11, then Tenant, as its sole remedy, shall be entitled to receive an abatement of Rent payable hereunder during the period beginning on the 6^th consecutive business day of the service interruption and ending on the day the service has been restored.

6.2. OPERATION AND MAINTENANCE OF COMMON AREAS. During the Term, Landlord shall operate all Common Areas within the Building and the Project. The term “Common Areas” shall mean all areas within the Building, Project, and other buildings in the Project which are not held for exclusive use by persons entitled to occupy space.

6.3. 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 set forth in Exhibit E. Landlord shall at all times during the Term have exclusive control of the Common Areas, and may restrain or permit any use or occupancy. 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.

ARTICLE 7. REPAIRS AND MAINTENANCE

7.1. TENANT’S MAINTENANCE AND REPAIR. 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 good condition and repair. Tenant’s maintenance obligation shall include without limitation all appliances, interior glass, doors, door closures, hardware, fixtures, electrical, plumbing, fire extinguisher equipment and other equipment installed in the Premises, together with any supplemental HVAC equipment servicing only the Premises. Should Landlord or its management agent agree to make a repair on behalf of Tenant and at ▇▇▇▇▇▇’s request, Tenant shall promptly reimburse Landlord as additional rent for all reasonable costs incurred (including the standard supervision fee) upon submission of an invoice.

7.2. LANDLORD’S MAINTENANCE AND REPAIR. Subject to Articles 11 and 12, Landlord shall provide service, maintenance and repair with respect to the heating, ventilating and air conditioning (“HVAC”) equipment of the Building (exclusive of any supplemental HVAC equipment servicing only the Premises) and shall maintain in good repair the Common Areas, roof (including roof membrane), foundations, footings, the exterior surfaces of the exterior walls of the Building (including exterior glass), and the structural, electrical, mechanical and plumbing systems of the Building (including elevators, if any, serving the Building), except to the extent provided in Section 7.1 above. 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 ▇▇▇▇▇▇’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. 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, decorations, or improvements (collectively referred to as “Alterations”) to the Premises without the prior written consent of Landlord. Landlord may impose, as a condition to its consent, any requirements that Landlord in its discretion may deem reasonable or desirable. Tenant shall use Landlord’s designated mechanical and electrical contractors, 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 5% of the cost of the Alterations. Landlord may elect to cause its architect to review ▇▇▇▇▇▇’s architectural plans, and the reasonable cost of that review shall be reimbursed by ▇▇▇▇▇▇. Should the Alterations proposed by ▇▇▇▇▇▇ 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. Unless Landlord otherwise agrees in writing, all Alterations affixed to the Premises, including without limitation all Tenant Improvements constructed pursuant to the Work Letter (except as otherwise provided in the Work Letter), but excluding moveable trade fixtures 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, by notice to Tenant given at the time of Landlord’s approval, require Tenant to remove by the Expiration Date or sooner termination date of this Lease, all or any Alterations (including without limitation any Tenant Improvements constructed pursuant to the Work Letter) installed either by Tenant or by Landlord at Tenant’s request (collectively, the “Required Removables”). 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.

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. In the event that Tenant shall not, within 15 days following the imposition of any lien, cause the lien to be released of record by payment or posting of a proper bond in accordance with California Civil Code Section 8424 or any successor statute, 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 expenses so incurred by Landlord shall be reimbursed by ▇▇▇▇▇▇ promptly following ▇▇▇▇▇▇▇▇’s demand. Tenant shall give Landlord no less than 20 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 and with reasonable prior verbal notice, except in emergencies or to provide Building services, 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,

6

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.

ARTICLE 8. SPACE PLANNING AND SUBSTITUTION

Landlord shall have the right, upon providing not less than 180 days’ prior written notice, to move Tenant to other space of comparable size in the Building or in the Project or in other space owned by Landlord or its affiliate(s) within 3 miles of the Building. The new space shall be provided with improvements of comparable quality to those within the Premises and shall contain similar finishes as the Premises, approximately the same rentable square footage as the Premises and approximately the same number of work stations, offices, breakrooms and reception areas as are contained in the Premises as of the date Tenant receives Landlord’s notice of relocation. The total monthly Basic Rent for the new space shall in no event exceed the total monthly Basic Rent for the Premises prior to the relocation and Tenant’s Share for the new space shall in no event exceed ▇▇▇▇▇▇’s Share for the Premises prior to the relocation. Landlord shall pay the reasonable out-of-pocket costs to relocate and reconnect Tenant’s personal property and equipment within the new space. Landlord shall also reimburse Tenant for such other reasonable out-of-pocket costs that Tenant may incur in connection with the relocation. Within 10 days following request by ▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇ shall execute an amendment to this Lease prepared by Landlord to memorialize the relocation. Notwithstanding the foregoing, if Landlord provides Tenant with a notice of relocation and Tenant, in its reasonable judgment, determines that the new space is not of reasonably comparable size and utility when compared to the Premises, Tenant shall have the right to terminate this Lease by giving written notice of termination to Landlord within 10 days after the date of Landlord’s notice of relocation to Tenant. Tenant’s notice of termination shall set forth the reasons why ▇▇▇▇▇▇ believes the new space is not comparable to the Premises. Such termination shall be effective 180 days after the date of Landlord’s notice of relocation, provided that Landlord, within 10 days after receipt of Tenant’s notice of termination, shall have the right to withdraw its notice of relocation. In such event, this Lease shall continue in full force and effect as if Landlord had never provided Tenant with a notice of relocation.

ARTICLE 9. ASSIGNMENT AND SUBLETTING

9.1. RIGHTS OF PARTIES. Tenant shall not, directly or indirectly, assign, sublease, transfer or encumber any interest in this Lease or allow any third party to use any portion of the Premises (collectively or individually, a “Transfer”) without the prior written consent of Landlord, which consent shall not be unreasonably withheld if Landlord does not exercise its recapture rights. ▇▇▇▇▇▇ agrees that it is not unreasonable for Landlord to withhold consent to a Transfer to a proposed assignee or subtenant who is an existing tenant or occupant of the Building or Project or to a prospective tenant with whom Landlord or Landlord’s affiliate has been actively negotiating. Any attempted Transfer in violation of this Article shall be a Default by Tenant and shall, at Landlord’s option, be void. Within 30 days after receipt of executed copies of the transfer documentation and such other information as Landlord may request, Landlord shall either: (a) consent to the Transfer by execution of a consent agreement in a form reasonably designated by Landlord; (b) refuse to consent to the Transfer; or (c) recapture the portion of the Premises that ▇▇▇▇▇▇ is proposing to Transfer. Tenant hereby waives the provisions of Section 1995.310 of the California Civil Code, or any similar or successor Laws, now or hereinafter in effect, and all other remedies, including, without limitation, any right at law or equity to terminate this Lease, on its own behalf and, to the extent permitted under all applicable laws, on behalf of the proposed transferee. In no event shall any Transfer release or relieve Tenant from any obligation under this Lease, as same may be amended. Tenant shall pay Landlord a review fee of $1,000.00 for Landlord’s review of any requested Transfer. Tenant shall pay Landlord, as additional Rent, 50% of all rent and other consideration which ▇▇▇▇▇▇ receives as a result of a Transfer that is in excess of the Rent payable to Landlord for the portion of the Premises and Term covered by the Transfer. If Tenant is in Default, Landlord may require that all sublease payments be made directly to Landlord, in which case Tenant shall receive a credit against Rent in the amount of Tenant’s share of payments received by Landlord.

9.2. PERMITTED TRANSFER. Notwithstanding the foregoing, Tenant may assign this Lease to a successor to Tenant by merger, consolidation or the purchase of substantially all of Tenant’s assets, or assign this Lease or sublet all or a portion of the Premises to an Affiliate (defined below), without the consent of Landlord, provided that all of the following conditions are satisfied (a “Permitted Transfer”): (i) Tenant is not then in Default hereunder; (ii) Tenant gives Landlord written notice prior to such Permitted Transfer; and (iii) if Tenant ceases to exist as a going concern as a result of any merger or consolidation of Tenant or the sale of all or substantially all of the assets of Tenant, the resulting successor entity has a tangible net worth not less than the tangible net worth of Tenant immediately before the Permitted Transfer. “Affiliate” shall mean an entity controlled by, controlling or under common control with Tenant.

ARTICLE 10. INSURANCE AND INDEMNITY

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. TENANT’S INDEMNITY. To the fullest extent permitted by law, but subject to Section 10.4 below, Tenant shall defend, indemnify and hold harmless Landlord and Landlord’s agents, employees, lenders, and affiliates, from and against any and all negligence, claims, liabilities, damages, costs or expenses arising either before or after the Commencement Date which arise from or are caused by Tenant’s use or occupancy of the Premises, the Building or the Common Areas of the Project, or from the conduct of Tenant’s business, or from any activity, work, or thing done, permitted or suffered by Tenant or Tenant’s agents, employees, subtenants, vendors, contractors, invitees or licensees in or about the Premises, the Building or the Common Areas of the Project, or from any Default in the performance of any obligation on Tenant’s part to be performed under this Lease, or from any act, omission or negligence on the part of Tenant or Tenant’s agents, employees, subtenants, vendors, contractors, invitees or licensees. Landlord may, at its option, require Tenant to assume Landlord’s defense in any action covered by this Section 10.2 through counsel reasonably satisfactory to Landlord. 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.

10.3. WAIVER OF CLAIMS. 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, regardless of the negligence of Landlord, its agents or any and all affiliates of Landlord in connection with the foregoing. 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.

10.4. WAIVER OF SUBROGATION. Landlord and ▇▇▇▇▇▇ waive all rights of recovery against the other on account of loss and damage 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.

ARTICLE 11. DAMAGE OR DESTRUCTION

11.1. RESTORATION.

(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; (ii) any Mortgagee (defined in Section 13.1) requires that the insurance proceeds be applied to the payment of the mortgage debt; or (iii) proceeds necessary to pay the full cost of the repair are not available from Landlord’s insurance, including without limitation earthquake insurance. 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 and if the damage is so extensive as to reasonably prevent Tenant’s substantial use and enjoyment of the Premises, then either party may elect to terminate this Lease by written notice to the other within 10 days following delivery of the Casualty Notice.

(c) In the event that neither Landlord nor Tenant terminates this Lease pursuant to Section 11.1(b), Landlord shall 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 Alterations. Within 15 days of demand, Tenant shall also pay Landlord for any additional excess costs that are determined during the performance of the repairs to such Alterations.

(d) From and after the 6^th business day following 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 the provisions of subsections (a), (b) and (c) of this Section 11.1, but subject to Section 10.4, the cost of any repairs shall be borne by Tenant, and Tenant shall not be entitled to rental abatement or termination rights, if the damage is due to the fault or neglect of Tenant or its employees, subtenants, contractors, invitees or representatives.

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.

ARTICLE 12. EMINENT DOMAIN

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 or Project. The termination shall be effective as of the effective date of any order granting possession to, or vesting legal title in, the condemning authority. All compensation awarded for a Taking shall be the property of Landlord. Tenant agrees that the provisions of this Lease shall govern any Taking and shall accordingly supersede any contrary statute or rule of law.

ARTICLE 13. SUBORDINATION; ESTOPPEL CERTIFICATE

13.1. SUBORDINATION. ▇▇▇▇▇▇ accepts this Lease subject and subordinate to any mortgage(s), deed(s) of trust, ground lease(s) or other lien(s) now or subsequently arising upon the Building or the Project, and to renewals, modifications, refinancings and extensions thereof (collectively referred to as a “Mortgage”). The party having the benefit of a Mortgage shall be referred to as a “Mortgagee.” This clause shall be self-operative, but upon request from a Mortgagee, Tenant shall execute a commercially reasonable subordination and attornment agreement in favor of the

8

Mortgagee, provided such agreement provides a non-disturbance covenant benefitting Tenant. Alternatively, a Mortgagee shall have the right at any time to subordinate its Mortgage to this Lease. Upon request, ▇▇▇▇▇▇, without charge, shall attorn to any successor to ▇▇▇▇▇▇▇▇’s interest in this Lease in the event of a foreclosure of any Mortgage. Tenant agrees that any purchaser at a foreclosure sale or lender taking title under a deed in lieu of foreclosure 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 ▇▇▇▇▇▇▇▇’s Mortgagees and their successors-in-interest are intended third party beneficiaries of this Section 13.1.

Notwithstanding the foregoing in this Section to the contrary, as a condition precedent to the future subordination of this Lease to a future Mortgage, Landlord shall be required, upon Tenant’s request, to provide Tenant with a non-disturbance, subordination, and attornment agreement in favor of Tenant from any Mortgagee who comes into existence after the Commencement Date. “Reasonable efforts” of Landlord shall not require Landlord to incur any cost, expense or liability to obtain such agreement, it being agreed that Tenant shall be responsible for any fee or review costs charged by the Mortgagee. Such non-disturbance, subordination, and attornment agreement in favor of Tenant shall provide that, so long as Tenant is paying the Rent due under the Lease and is not otherwise in default under the Lease beyond any applicable cure period, its right to possession and the other terms of the Lease shall remain in full force and effect. Such non-disturbance, subordination, and attornment agreement may include other commercially reasonable provisions in favor of the Mortgagee, including, without limitation, additional time on behalf of the Mortgagee to cure defaults of the Landlord and provide that (a) neither Mortgagee nor any successor-in-interest shall be bound by (i) any payment of the Rent, or other sum due under this Lease for more than 1 month in advance (unless required by this Lease) or (ii) any amendment or modification of the Lease made without the express written consent of Mortgagee or any successor-in-interest; (b) neither Mortgagee nor any successor-in-interest will be liable for (i) any act or omission or warranties of any prior landlord (including Landlord), other than defaults of a continuing nature, (ii) the breach of any warranties or obligations relating to construction of improvements on the Building or any tenant finish work performed or to have been performed by any prior landlord (including Landlord), or (iii) the return of any Security Deposit, except to the extent such deposits have been received by Mortgagee; and (c) neither Mortgagee nor any successor-in-interest shall be subject to any offsets or defenses which Tenant might have against any prior landlord (including Landlord).

13.2. ESTOPPEL CERTIFICATE. Tenant shall, within 10 days after receipt of a written request from 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).

ARTICLE 14. DEFAULTS AND REMEDIES

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 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 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 ▇▇▇▇▇▇, other than as specified in any other subsection of this Section 14.1, 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.

14.2. LANDLORD’S REMEDIES. In addition to all other rights or remedies of Landlord set forth in this Lease, if a Default occurs, Landlord shall have all rights available to Landlord under California law, without further notice or demand to Tenant, including, without limitation, the right to terminate this Lease. In addition, ▇▇▇▇▇▇▇▇ has the remedy described in California Civil Code Section 1951.4 (Landlord may continue this Lease in effect after ▇▇▇▇▇▇’s breach and abandonment and recover Rent as it becomes due, if ▇▇▇▇▇▇ has the right to sublet or assign, subject only to reasonable limitations). In any case in which Landlord re-enters and occupies the Premises, by unlawful detainer proceedings or otherwise, Landlord, at its option, may repair, alter, subdivide or change the character of the Premises as Landlord deems best, relet all or any part of the Premises and receive the rents therefor, and none of these actions shall constitute a termination of this Lease, a release of Tenant from any liability, or result in the release of any Guarantor. Landlord shall not be deemed to have terminated this Lease or the liability of Tenant to pay any Rent or other charges later becoming due by any re-entry of the Premises pursuant to this Section 14.2, or by any action in unlawful detainer or otherwise to obtain possession of the Premises, unless ▇▇▇▇▇▇▇▇ has first given Tenant notice that it is terminating this Lease. Any notice given by Landlord pursuant to Section 14.1 shall be in lieu of, and not in addition to, any notice required by Section 1161 of the California Code of Civil Procedure or superseding statute. Any payment of Rent following Landlord’s delivery of notice to Tenant pursuant to Section 14.1 shall not constitute acceptance of Rent. If Landlord elects to terminate this Lease pursuant to the provisions of this Section 14.2, damages shall include, without limitation, the remedy and measure of damages specified pursuant to California Civil Code Section 1951.2, which shall include 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 Rent

9

loss Tenant proves could have been reasonably avoided. ▇▇▇▇▇▇▇▇ agrees to use reasonable efforts to mitigate damages, provided that those efforts shall not require Landlord to relet the Premises in preference to any other space in the Project or to relet the Premises to any party that Landlord could reasonably reject as a transferee pursuant to Article 9. If a Default by Tenant occurs, Landlord shall not be entitled to recover any resulting consequential damages, lost profit or opportunity costs, provided that nothing contained in this Section 14.2(c) shall limit or otherwise restrict Landlord’s right to recover damages resulting from ▇▇▇▇▇▇’s breach of its obligations under Sections 5.3, 7.4, 13.2, and/or 15.1 of this Lease, or Landlord’s right to recover any amounts described in California Civil Code Section 1951.2.

14.3. LATE PAYMENTS. 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 and 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, a late charge for each delinquent payment equal to the greater of (i) 5% of that delinquent payment or (ii) $100.00.

14.4. 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.

14.5. 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.

14.6. JUDICIAL REFERENCE/ WAIVER OF JURY TRIAL. ▇▇▇▇▇▇▇▇ and ▇▇▇▇▇▇ 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 14.6 shall apply to an unlawful detainer action. 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, TO THE EXTENT PERMITTED BY LAW, EACH PARTY DOES HEREBY EXPRESSLY AND KNOWINGLY WAIVE AND RELEASE ALL SUCH RIGHTS TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS LEASE.

14.7. 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, and no action for any deficiency may be sought or obtained by ▇▇▇▇▇▇.

ARTICLE 15. END OF TERM

15.1. HOLDING OVER. If Tenant holds over for any period after the Expiration Date (or earlier termination of the Term), such tenancy shall constitute a tenancy at sufferance only and possession shall be subject to all of the terms of this Lease, except that the monthly rental shall be 200% of the total monthly rental for the month immediately preceding the date of termination. 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 ▇▇▇▇▇▇ 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 when received or as hereafter may be improved by Landlord or Tenant, reasonable wear and tear and repairs which are Landlord’s obligation excepted, and shall remove or fund to Landlord the cost of removing 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. If Tenant shall fail to comply with the provisions of this Section 15.2, and remove any personal property within 10 days following the expiration or earlier termination of this Lease, such personal property shall be conclusively deemed to have been abandoned, then Landlord may effect the removal and/or make any repairs, without notice and without incurring any liability to Tenant, and the cost to Landlord shall be additional rent payable by Tenant upon demand. Tenant hereby waives all rights under and benefits of Section 1993.03 of the California Civil Code, or any similar or successor laws now or hereafter in effect and authorizes Landlord to dispose of any personal property remaining at the Premises following the expiration or earlier termination of this Lease without further notice to Tenant.

ARTICLE 16. PAYMENTS AND NOTICES

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, 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

10

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.

ARTICLE 17. RULES AND REGULATIONS

▇▇▇▇▇▇ 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 by Landlord from time to time (provided such rules and regulations adopted by Landlord after the date of this Lease shall not impose any additional unreasonable burdens or additional unreasonable liabilities on Tenant). The rules and regulations shall be generally applicable, and generally applied in the same manner, to all tenants of the Project.

ARTICLE 18. BROKER’S COMMISSION

The parties recognize as the broker(s) who negotiated this Lease the firm(s) whose name(s) is (are) stated in Item 10 of the Basic Lease Provisions, and agree that Landlord shall be responsible for the payment of brokerage commissions to those broker(s) unless otherwise provided in this Lease. ▇▇▇▇▇▇ agrees to indemnify and hold Landlord 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 ▇▇▇▇▇▇ in connection with the negotiation of this Lease.

ARTICLE 19. TRANSFER OF LANDLORD’S INTEREST

Landlord shall have the right to transfer and assign, in whole or in part, all of its ownership interest, rights and obligations in the Building, Project or Lease, including the Security Deposit, and upon transfer Landlord shall be released from any further obligations hereunder, and ▇▇▇▇▇▇ agrees to look solely to the successor in interest of Landlord for the performance of such obligations and the return of any Security Deposit.

ARTICLE 20. INTERPRETATION

20.1. 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.

20.2. 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.

20.3. 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.

20.4. CONTROLLING LAW. This Lease shall be governed by and interpreted in accordance with the laws of the State of California.

20.5. 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.

20.6. 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.

20.7. 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 20.7 shall not operate to excuse Tenant from the prompt payment of Rent.

20.8. ENTIRE AGREEMENT. This Lease constitutes the entire agreement between the parties and supersedes all prior agreements and understandings related to the Premises. This Lease may be modified only by a written agreement signed by Landlord and ▇▇▇▇▇▇.

20.9. 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.

11

20.10. 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.

ARTICLE 21. EXECUTION

21.1. COUNTERPARTS; DIGITAL SIGNATURES. 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. The parties agree to accept a digital image (including but not limited to an image in the form of a PDF, JPEG, GIF file, or other e-signature) of this Lease, if applicable, reflecting the execution of one or both of the parties, as a true and correct original.

21.2. CORPORATE AND PARTNERSHIP AUTHORITY. Tenant and each individual executing this Lease represents and warrants to Landlord, and agrees, that such individual executing this Lease on behalf of Tenant is authorized to do so on behalf of Tenant.

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 ▇▇▇▇▇▇ 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 ▇▇▇▇▇▇▇▇ and delivery of a fully executed counterpart to Tenant.

21.4. BROKER DISCLOSURE. By the execution of this Lease, each of Landlord and Tenant hereby acknowledge and confirm (a) receipt of a copy of a Disclosure Regarding Real Estate Agency Relationship conforming to the requirements of California Civil Code 2079.16, and (b)the agency relationships specified in Item 10 of the Basic Lease Provisions, which acknowledgement and confirmation is expressly made for the benefit of Tenant’s Broker identified in Item 10 of the Basic Lease Provisions. If there is no Tenant’s Broker so identified in Item 10 of the Basic Lease Provisions, then such acknowledgement and confirmation is expressly made for the benefit of Landlord’s Broker. By the execution of this Lease, Landlord and Tenant are executing the confirmation of the agency relationships set forth in Item 10 of the Basic Lease Provisions.

ARTICLE 22. MISCELLANEOUS

22.1. NONDISCLOSURE OF LEASE TERMS. Except to the extent disclosure is required by law, Tenant shall keep the content of this Lease and any related documents confidential and shall not disclose such confidential information to any person or entity other than Tenant’s financial, legal and space-planning consultants, provided, however, that Tenant may disclose the terms to prospective subtenants or assignees under this Lease or pursuant to legal requirement.

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 ▇▇▇▇▇▇’s financial condition upon written request from Landlord within 10 days following ▇▇▇▇▇▇▇▇’s request; 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.

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. 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.

22.5. CONSENT/DUTY TO ACT REASONABLY. Except where a party is expressly given the right to consent to any matter in its sole or absolute discretion, and except for matters which could have an adverse effect on the Building structure or Building systems or affect the exterior appearance of the Building, whereupon in each such case Landlord’s duty is to act in good faith and in compliance with the Lease, any time the consent of Landlord or Tenant is required, such consent shall not be unreasonably withheld, conditioned or delayed. Whenever the Lease grants Landlord or Tenant the right to take action, exercise discretion, establish rules and regulations or make allocations or other determinations (other than decisions to exercise expansion, contraction, cancellation, termination or renewal options), then except as otherwise provided herein, Landlord and Tenant shall act reasonably and in good faith and take no action which might result in the frustration of the reasonable expectations of a sophisticated tenant or landlord concerning the benefits to be enjoyed under the Lease.

IN WITNESS WHEREOF, the parties have executed this Lease as of the day and year first above written.

Exhibit A

EXHIBIT A-1

EXHIBIT B

OPERATING EXPENSES

(Net)

(a) From and after the Commencement Date, Tenant shall pay to Landlord, as additional rent, ▇▇▇▇▇▇’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 that portion of any Operating Expenses determined by multiplying the cost of such item by a fraction, the numerator of which is the Floor Area of Premises and the denominator of which is the total rentable square footage, as determined from time to time by Landlord, of (i) the Building, for expenses determined by Landlord to benefit or relate substantially to the Building rather than the entire Project, and (ii) all or some of the buildings in the Project, for expenses determined by Landlord to benefit or relate substantially to all or some of the buildings in the Project rather than any specific building. Landlord reserves the right to allocate to the entire Project any Operating Expenses which may benefit or substantially relate to a particular building within the Project in order to maintain greater consistency of Operating Expenses among buildings within the Project. In the event that Landlord 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 next coming due under this Exhibit B, and any deficiency shall be paid by Tenant together with the next installment. Should Tenant fail to object in writing to Landlord’s determination of Tenant’s Share of Operating Expenses within 60 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.

(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.

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.

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, on a policy form that is at least as broad as Insurance Service Office (ISO) CGL 00 01 (if alcoholic beverages are sold on the Premises, liquor liability shall be explicitly covered), which policy(ies) shall be written on an “occurrence” basis and for not less than $2,000,000 combined single limit per occurrence 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 each accident and each disease; (iii) with respect to 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 Alterations, trade fixtures, furnishings, equipment and items of personal property in the Premises, in an amount equal to not less than 90% of their 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 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, provides the coverage required by this Exhibit and contains the required provisions, together with endorsements acceptable to Landlord evidencing the waiver of subrogation and additional insured provisions required below, 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 30 days prior to 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, The Irvine Company LLC, 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 same policies enumerated above. All of Tenant’s policies shall contain a provision that the insurer will not cancel or change 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.

NOTICE TO TENANT: IN ACCORDANCE WITH THE TERMS OF THIS LEASE, TENANT MUST PROVIDE EVIDENCE OF THE REQUIRED INSURANCE TO LANDLORD’S MANAGEMENT AGENT PRIOR TO BEING AFFORDED ACCESS TO THE PREMISES.

EXHIBIT F

PARKING

Tenant shall be entitled to the number of vehicle parking spaces set forth in Item 11 of the Basic Lease Provisions, which spaces shall be unreserved and unassigned and at no additional charge to Tenant during the initial Term, on those portions of the Common Areas designated by Landlord for parking. Tenant shall not use more parking spaces than such number. All parking spaces shall be used only for parking of vehicles no larger than full size passenger automobiles, sport utility vehicles or pickup trucks. Tenant shall not permit or allow any vehicles that belong to or are controlled by Tenant or Tenant’s employees, suppliers, shippers, customers or invitees to be loaded, unloaded or parked in areas other than those designated by Landlord for such activities (which areas include the apron outside of the roll-up doors at the rear of the Premises). If Tenant permits or allows any of the prohibited activities described above, then Landlord shall have the right, without notice, in addition to such other rights and remedies that Landlord may have, to remove or tow away the vehicle involved and charge the costs to Tenant. Parking within the Common Areas shall be limited to striped parking stalls, and no parking shall be permitted in any driveways, access ways or in any area which would prohibit or impede the free flow of traffic within the Common Areas. There shall be no parking of any vehicles for longer than a 48 hour period unless otherwise authorized by Landlord, and vehicles which have been abandoned or parked in violation of the terms hereof may be towed away at the owner’s expense. Nothing contained in this Lease shall be deemed to create liability upon Landlord for any damage to motor vehicles of visitors or employees, for any loss of property from within those motor vehicles, or for any injury to Tenant, its visitors or employees, unless ultimately determined to be caused by the sole negligence or willful misconduct of Landlord. Landlord shall have the right to establish, and from time to time amend, and to enforce against all users all reasonable rules and regulations (including the designation of areas for employee parking) that Landlord may deem necessary and advisable for the proper and efficient operation and maintenance of parking within the Common Areas. Landlord shall have the right to construct, maintain and operate lighting facilities within the parking areas; to change the area, level, location and arrangement of the parking areas and improvements therein; to restrict parking by tenants, their officers, agents and employees to employee parking areas; to enforce parking charges (by operation of meters or otherwise); and to do and perform such other acts in and to the parking areas and improvements therein as, in the use of good business judgment, Landlord shall determine to be advisable, provided that Tenant shall at all times be provided with the number of vehicle parking spaces set forth in Item 11 of the Basic Lease Provisions. Any person using the parking area shall observe all directional signs and arrows and any posted speed limits.

ADDITIONAL PROVISIONS

1. EARLY ENTRY. Following mutual execution of this Lease and Landlord obtaining possession of the Premises from the current tenant thereof, Landlord agrees that Tenant shall be permitted to enter the Premises prior to the Commencement Date of this Lease in order for Tenant to install its furniture, fixtures and equipment, subject to the following terms and conditions: (a) concurrently with the execution and delivery of this Lease, and prior to any such early entry by ▇▇▇▇▇▇, Tenant shall deliver to Landlord (i) the first installment of Basic Rent and Operating Expenses due under the Lease, (ii) the Security Deposit set forth in Item 9 of the Basic Lease Provisions, and (iii) the required certificate(s) of insurance; and (b) Tenant’s occupancy of the Premises prior to the Commencement Date pursuant to this Section shall be subject to all of the covenants and conditions on Tenant’s part contained in this Lease (including, without limitation, the covenants contained in Sections 5.3, 6.1, 7.1, 7.3, 7.4, 10.1 and 10.2 of the Lease), except for the obligation to pay Basic Rent and Operating Expenses.

2. RIGHT TO EXTEND. Provided that Tenant is not in Default under any provision of this Lease at the time of exercise of the extension right granted herein, and provided further that Tenant is occupying the entire Premises and has not assigned or sublet any of its interest in this Lease (except in connection with a Permitted Transfer of this Lease as described in Section 9.2 hereof), Tenant may extend the Term of this Lease for one period of 60 months. Tenant shall exercise its right to extend the Term by and only by delivering to Landlord, not less than 9 months nor more than 12 months prior to the expiration date of the Term, ▇▇▇▇▇▇’s written notice of its irrevocable commitment to extend (the “Commitment Notice”). Should Tenant fail timely to deliver the Commitment Notice, then this extension right shall thereupon lapse and be of no further force or effect.

The Basic Rent payable under the Lease during the extension of the Term shall be at the prevailing market rental rate (including periodic adjustments) for comparable and similarly improved office space being leased by Landlord in the Project or other comparable projects owned by Landlord in the Irvine Spectrum area as of the commencement of the extension period, based on a reasonable extrapolation of Landlord’s then-current leasing rates (the “Prevailing Rate”); provided that such Basic Rent shall in no event be less than the Basic Rent payable by ▇▇▇▇▇▇ during the final month of the Term. In the event that the parties are not able to agree on the Prevailing Rate within 120 days prior to the expiration date of the Term, then either party may elect, by written notice to the other party, to cause said rental, including subsequent adjustments, to be determined by appraisal as follows.

Within 10 days following receipt of such appraisal election, the parties shall attempt to agree on an appraiser to determine the Prevailing Rate. If the parties are unable to agree in that time, then each party shall designate an appraiser within 10 days thereafter. Should either party fail to so designate an appraiser within that time, then the appraiser designated by the other party shall determine the Prevailing Rate. Should each of the parties timely designate an appraiser, than the two appraisers so designated shall appoint a third appraiser who shall, acting alone, determine the fair market rental value of the Premises. Any appraiser designated hereunder shall have an M.A.I. certification or equivalent with not less than 5 years’ experience in the valuation of commercial office buildings in Orange County, California.

Within 10 days following the selection of the appraiser, Landlord and Tenant shall each submit in writing to the appraiser its determination of the rental rate for the extension period (respectively, the “Landlord’s Determination” and the “Tenant’s Determination”). Should either party fail timely to submit its rental determination, then the determination of the other party shall be conclusive and binding on the parties. The appraiser shall not disclose to either party the rental determination of the other party until the expiration of that 10 day period or, if sooner, the appraiser’s receipt of both the Landlord’s Determination and the Tenant’s Determination.

Within 30 days following the selection of the appraiser and such appraiser’s receipt of the Landlord’s Determination and the Tenant’s Determination, the appraiser shall determine whether the rental rate determined by Landlord or by Tenant more accurately reflects Prevailing Rate for the Premises, as reasonably extrapolated to the commencement of the extension term. Accordingly, either the Landlord’s Determination or the Tenant’s Determination shall be selected by the appraiser as the fair market rental rate for the extension period. In determining such value, the appraiser shall first consider rental comparables for the Building and the Project, provided that if adequate comparables do not exist then the appraiser may consider transactions involving similarly improved space owned by Landlord or its affiliates in the vicinity with appropriate adjustments for differences in location and quality of project. In no event shall the appraiser attribute factors for market tenant improvement allowances or brokerage commissions to reduce said fair market rental. At any time before the decision of the appraiser is rendered, either party may, by written notice to the other party, accept the rental terms submitted by the other party, in which event such terms shall be deemed adopted as the agreed fair market rental. The fees of the appraiser(s) shall be shared equally by both parties.

Within 20 days after the determination of the Prevailing Rate, Landlord shall prepare a reasonably appropriate amendment to this Lease for the extension period and Tenant shall execute and return same to Landlord within 10 days. Should the Prevailing Rate not be established by the commencement of the extension period, then Tenant shall continue paying rent at the rate in effect during the last month of the initial Term, and a lump sum adjustment shall be made promptly upon the determination of such new rental.

If Tenant fails to timely comply with any of the provisions of this paragraph, ▇▇▇▇▇▇’s right to extend the Term may, at Landlord’s election and in addition to any other remedies that may be available to Landlord, be extinguished, in which event the Lease shall automatically terminate as of the initial expiration date of the Term. Any attempt to assign or transfer any right or interest created by this Section to other than in connection with a Permitted Transfer shall be void from its inception. Tenant shall have no other right to extend the Term beyond the single 60-month extension created by this Section. Unless agreed to in a writing signed by Landlord and Tenant, any extension of the Term, whether created by an amendment to the Lease or by a holdover of the Premises by Tenant, or otherwise, shall be deemed a part of, and not in addition to, any duly exercised extension period permitted by this paragraph. Time is specifically made of the essence in this Section.

3. RIGHT OF FIRST OFFER. Provided Tenant is not then in Default hereunder, and provided further that Tenant is occupying the entire Premises and has not assigned or sublet any of its interest in the Lease (except in connection with a Permitted Transfer of this Lease to an Affiliate as described in Section 9.2 hereof), Landlord hereby grants Tenant a one-time right (“First Right”) to lease, during the initial 84-month Term of this Lease, approximately 11,193 rentable square feet of office space known as Suite No. 100 in the Building and shown on Exhibit A-1 hereto (“First Right Space”) in accordance with and subject to the provisions of this Section; provided that this First Right shall cease to be effective during the final 12 months of the Term unless and until Tenant exercises its extension option set forth in Section 2 of this Exhibit G. It is understood, however, that ▇▇▇▇▇▇’s First Right is expressly conditioned upon (a) the prior delivery by Tenant of written notice to Landlord in good faith of ▇▇▇▇▇▇’s need for additional space (the “Space Requirement Notice”), which Space Requirement Notice shall be valid for a period of 6 months only (after which time period, Tenant must deliver an additional Space Requirement Notice to Landlord), and (b) Landlord, at the time Landlord receives such Space Requirement Notice, not then being in agreement with a third party to lease such First Right Space. If, at any time after the Commencement Date and following delivery of a Space Requirement Notice and while this First Right is in effect, Landlord desires to lease the First Right Space, or any portion thereof, to any third party, Landlord shall give Tenant written notice of the basic economic terms including but not limited to the Basic Rent, term, operating expense base, security deposit, and tenant improvement allowance (collectively, the “Economic Terms”), upon which Landlord is willing to lease such particular First Right Space to Tenant or to a third party; provided that the Economic Terms shall exclude brokerage commissions and other Landlord payments that do not directly inure to the tenant’s benefit. It is understood that should Landlord intend to lease other office space in addition to the First Right Space as part of a single transaction, then Landlord’s notice shall so provide and all such space shall collectively be subject to the following provisions. Within 3 business days after receipt of Landlord’s notice, Tenant must give Landlord written notice pursuant to which Tenant shall elect to (i) lease all, but not less than all, of the space specified in Landlord’s notice (the “Designated Space”) upon such Economic Terms and the same non-Economic Terms as set forth in this Lease; (ii) refuse to lease the Designated Space, specifying that such refusal is not based upon the Economic Terms, but upon ▇▇▇▇▇▇’s lack of need for the Designated Space, in which event Landlord may lease the Designated Space upon any terms it deems appropriate; or (iii) refuse to lease the Designated Space, specifying that such refusal is based upon said Economic Terms, in which event Tenant shall also specify revised Economic Terms upon which Tenant shall be willing to lease the Designated Space. In the event that ▇▇▇▇▇▇ does not so respond in writing to Landlord’s notice within said period, Tenant shall be deemed to have elected clause (ii) above. In the event Tenant gives Landlord notice pursuant to clause (iii) above, Landlord may elect to either (x) lease the Designated Space to Tenant upon such revised Economic Terms and the same other non-Economic Terms as set forth in this Lease, or (y) lease the Designated Space to any third party upon Economic Terms which are not materially more favorable to such party than those Economic Terms proposed by Tenant. Should Landlord so elect to lease the Designated Space to Tenant, then Landlord shall promptly prepare and deliver to Tenant an amendment to this Lease consistent with the foregoing, and Tenant shall execute and return same to Landlord within 10 days. Tenant’s failure to timely return the amendment shall entitle Landlord to specifically enforce Tenant’s commitment to lease the Designated Space, to lease such space to a third party, and/or to pursue any other available legal remedy. Notwithstanding the foregoing, it is understood that ▇▇▇▇▇▇’s First Right shall be subject to any extension or expansion rights previously granted by Landlord to any third party tenant in the Building, as well as to any such rights which may hereafter be granted by Landlord to any third party tenant occupying the First Right Space or any portion thereof, and Landlord shall in no event be obligated to initiate this First Right prior to leasing any portion of the First Right Space to the then-current occupant thereof. Tenant’s rights under this Section shall be personal to the original Tenant named in this Lease and may not be assigned or transferred (except in connection with a Permitted Transfer of this Lease to an Affiliate as described in Section 9.2 hereof). Any other attempted assignment or transfer shall be void and of no force or effect. Time is specifically made of the essence of this Section.

LANDLORD’S DISCLOSURES

SPECTRUM

The capitalized terms used and not otherwise defined in this Exhibit shall have the same definitions as set forth in the Lease. The provisions of this Exhibit shall supersede any inconsistent or conflicting provisions of the Lease.

1. Landlord has been informed that the El Toro Marine Corps Air Station (MCAS) has been listed as a Federal Superfund site as a result of chemical releases occurring over many years of occupancy. Various chemicals including jet fuel, motor oil and solvents have been discharged in several areas throughout the MCAS site. A regional study conducted by the Orange County Water District has estimated that groundwaters beneath more than 2,900 acres have been impacted by Trichloroethylene (TCE), an industrial solvent. There is a potential that this substance may have migrated into the ground water underlying the Premises. The U.S. Environmental Protection Agency, the Santa ▇▇▇ Regional Water Quality Control Board, and the Orange County Health Care Agency are overseeing the investigation/cleanup of this contamination. To the Landlord’s current actual knowledge, the ground water in this area is used for irrigation purposes only, and there is no practical impediment to the use or occupancy of the Premises due to the El Toro discharges.

Guarantor understands and agrees that its liability under this Guarantee shall be primary (and joint and several with Tenant) and that, in any right of action which may accrue to Landlord under the Lease or this Guarantee, Landlord at its option may proceed against Guarantor without having taken any action or obtained any judgment against Tenant.
