The parties hereto hereby acknowledge that the purpose of Exhibit 1.1.1-1 is to show the approximate location of the Premises in the “Building”, as that term is defined in Section 1.1.2, below, only, and such Exhibit is not meant to constitute an agreement, representation or warranty as to the construction of the Premises, the precise area thereof or the specific location of the “Common Areas,” as that term is defined in Section 1.1.3, below, or the elements thereof or of the accessways to the Premises or the “Project”, as that term is defined in Section 1.1.2, below.

If Landlord re-measures the Premises at any time during the Lease Term, the rentable square footage of the Premises will not be increased during the Lease Term as a consequence of any such re-measurement.

2. LEASE TERM

The term of this Lease (the “Lease Term”) shall be as set forth in Section 3.1 of the Summary, shall commence on the date set forth in Section 3.2 of the Summary (the “Lease Commencement Date”), and shall terminate on the date set forth in Section 3.4 of the Summary (the “Lease Expiration Date”) unless this Lease is sooner terminated as hereinafter provided. For purposes of this Lease, the term “Lease Year” shall mean the consecutive twelve (12) month period following and including the Rent Commencement Date and each subsequent twelve (12) month period during the Lease Term. At any time during the Lease Term, Landlord may deliver to Tenant a notice in the form as set forth in Exhibit 2.1, attached hereto, as a confirmation only of the information set forth therein, which Tenant shall execute and return to Landlord within ten (10) business days of receipt thereof, but execution of such instrument shall not be a condition to Lease commencement or Tenant’s obligations hereunder.

3. BASE RENT

3.1 Payment of Rent. Tenant shall pay, without prior notice or demand, at such place as Landlord may from time to time designate in writing, by a check for currency which, at the time of payment, is legal tender for private or public debts in the United States of America or pursuant to wire or electronic payment instructions provided by Landlord, base rent (“Base Rent”) as set forth in Section 4 of the Summary, payable in equal monthly installments as set forth in Section 4 of the Summary, in advance, on or before the first day of each and every calendar month during the Lease Term, without any setoff or deduction whatsoever. Base Rent for the first full month of the Lease Term shall be paid at the time of Tenant’s execution of this Lease. If any Rent payment date (including the Rent Commencement Date) falls on a day of the month other than the first day of such month or if any payment of Rent is for a period which is shorter than one month, the Rent for any fractional month shall accrue on a daily basis for the period from the date such payment is due to the end of such calendar month or to the end of the Lease Term at a rate per day which is equal to 1/365 of the applicable annual Rent. All other payments or adjustments required to be made under the terms of this Lease that require proration on a time basis shall be prorated on the same basis. Base Rent and Additional Rent shall together be denominated “Rent.” Without limiting the foregoing, Tenant’s obligation to pay Rent shall be absolute, unconditional and independent of any Landlord covenants and shall not be discharged or otherwise affected by any law or regulation ow or hereafter applicable to the Premises, or any other restriction on Tenant’s use, or (except as expressly provided herein), any casualty or taking, or any failure by Landlord to perform any covenant contained herein, or any other occurrence; provided, however, Tenant shall have the right to institute a suit for recovery of any damages suffered by Tenant as a consequence of a default by Landlord. Tenant’s covenants contained herein are independent and not dependent, and Tenant hereby waives the benefit of any statute or judicial law to the contrary.

3.2 Rents from Real Property. Landlord and Tenant hereby agree that it is their intent that all Base Rent, Additional Rent and other rent and charges payable to the Landlord under this Lease (hereinafter individually and collectively referred to as “Rent”) shall qualify as “rents from real property” within the meaning of Section 856(d) of the Internal Revenue Code of 1986, as amended (the “Code”), and the Department of the U.S. Treasury Regulations promulgated thereunder (the “Regulations”). Should the Code or the Regulations, or interpretations thereof by the Internal Revenue Service contained in revenue rulings or other similar public pronouncements, be changed so that any Rent no longer so qualifies as “rent from real property” for purposes of Section 856(d) of the Code and the Regulations promulgated thereunder, such Rent shall be adjusted in such manner as the Landlord may require so that it will so qualify; provided, however, that any adjustments required pursuant to this Section 7.3 shall not result in any increase in rents for any period of time (but shall otherwise be made so as to produce the equivalent (in economic terms) Rent as payable prior to such adjustment).

-6-

In addition to paying the Base Rent specified in Article 3 of this Lease, Tenant shall pay “Tenant’s Share” of the annual “Direct Expenses” as those terms are defined in Sections 4.2.6 and 4.2.2 of this Lease, respectively. Such payments by Tenant, together with any and all other amounts payable by Tenant to Landlord pursuant to the terms of this Lease other than Base Rent, are hereinafter collectively referred to as the “Additional Rent”. All amounts due under this Article 4 as Additional Rent shall be payable for the same periods and in the same manner as the Base Rent. Without limitation on other obligations of Tenant which survive the expiration of the Lease Term, the obligations of Tenant to pay the Additional Rent provided for in this Article 4 shall survive the expiration of the Lease Term.

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

4.2.1 Intentionally Omitted.

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

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

4.2.4 “Operating Expenses” shall mean all expenses, costs and amounts of every kind and nature which Landlord pays or accrues during any Expense Year because of or in connection with the ownership, management, maintenance, security, repair, replacement, restoration or operation of the Project, or any portion thereof.

In the event that Landlord or Landlord’s managers or agents perform services for the benefit of the Building off-site which would otherwise be performed on-site (e.g., accounting), the cost of such services shall be reasonably allocated among the properties benefitting from such service and shall be included in Operating Expenses. Notwithstanding the foregoing, for purposes of this Lease, Operating Expenses shall not, however, include:

(a) costs, including legal fees, space planners’ fees, advertising and promotional expenses, and brokerage fees incurred in connection with the original construction or development, or original or future leasing of the Project, and costs, including permit, license and inspection costs, incurred with respect to the installation of tenant improvements made for tenants or incurred in renovating or otherwise improving, decorating, painting or redecorating vacant space for tenants of the Project (excluding, however, such costs relating to any common areas of the Project);

(d) any bad debt loss, rent loss, or reserves for bad debts or rent loss;

(e) costs associated with the operation of the business of the partnership or entity which constitutes Landlord, as the same are distinguished from the costs of operation of the Project (which shall specifically include, but not be limited to, accounting costs associated with the operation of the Project). Costs associated with the operation of the business of the partnership or entity which constitutes Landlord include costs of partnership accounting and legal matters, costs of defending any lawsuits with any mortgagee (except as the actions of Tenant may be in issue), costs of selling, syndicating, financing, mortgaging or hypothecating any of Landlord’s interest in the Project, and costs incurred in connection with any disputes between Landlord and its employees, between Landlord and Project management, or between Landlord and other tenants or occupants;

(g) amount paid as ground rental for the Project by Landlord;

(i) any compensation paid to clerks, attendants or other persons in commercial concessions operated by Landlord, provided that any compensation paid to any concierge at the Project shall be includable as an Operating Expense;

(k) rent for any office space occupied by Project management personnel to the extent the size or rental rate of such office space exceeds the size or fair market rental value of office space occupied by management personnel of comparable buildings in the vicinity of the Building, with adjustment where appropriate for the size of the applicable project;

-8-

(l) costs incurred to comply with laws relating to the removal of Hazardous Materials (other than Hazardous Materials typically found in comparable buildings, such as recyclable materials and typical construction materials);

(m) Landlord’s general overhead expenses not related to the Project;

(n) legal fees, accountants’ fees (other than normal bookkeeping expenses) and other expenses incurred in connection with disputes of tenants or other occupants of the Project or associated with the enforcement of the terms of any leases with tenants or the defense of Landlord’s title to or interest in the Project or any part thereof;

(o) any reserve funds;

If Landlord is not furnishing any particular work or service (the cost of which, if performed by Landlord, would be included in Operating Expenses) to a tenant who has undertaken to perform such work or service in lieu of the performance thereof by Landlord, Operating Expenses shall be deemed to be increased by an amount equal to the additional Operating Expenses which would reasonably have been incurred during such period by Landlord if it had at its own expense furnished such work or service to such tenant. If the Project is not at least one hundred percent (100%) occupied during all or a portion of any Expense Year, Landlord shall make an appropriate adjustment to the components of Operating Expenses for such year to determine the amount of Operating Expenses that would have been incurred had the Project been one hundred percent (100%) occupied; and the amount so determined shall be deemed to have been the amount of Operating Expenses for such year.

4.2.5 Taxes.

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

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

-9-

the ad valorem tax on real or personal property, a capital levy or other tax on the gross rents or other measures of building operations, or a governmental income, franchise, excise or similar tax, assessment, levy, charge or fee measured by or based, in whole or in part, upon building valuation, gross rents or other measures of building operations or benefits of governmental services furnished to the Building, then any and all of such taxes, assessments, levies, charges and fees, to the extent so measured or based, shall be included within the term Tax Expenses, but only to the extent that the same would be payable if the Building and Land were the only property of Landlord.

4.2.5.3 Any costs and expenses (including, without limitation, reasonable attorneys’ and consultants’ fees) incurred in attempting to protest, reduce or minimize Tax Expenses shall be included in Tax Expenses in the Expense Year such expenses are incurred. Tax refunds shall be credited against Tax Expenses and refunded to Tenant regardless of when received, based on the Expense Year to which the refund is applicable, provided that in no event shall the amount to be refunded to Tenant for any such Expense Year exceed the total amount paid by Tenant as on account of Tax Expenses under this Article 4 for such Expense Year. The foregoing sentence shall survive the expiration or earlier termination of this Lease. If Tax Expenses for any period during the Lease Term or any extension thereof are increased after payment thereof for any reason, including, without limitation, error or reassessment by applicable governmental or municipal authorities, Tenant shall pay Landlord upon demand Tenant’s Share of any such increased Tax Expenses. Notwithstanding anything to the contrary contained in this Section 4.2.5, there shall be excluded from Tax Expenses (i) all excess profits taxes, franchise taxes, gift taxes, capital stock taxes, inheritance and succession taxes, estate taxes, transfer tax or fee, federal and state income taxes, and other taxes to the extent applicable to Landlord’s general or net income (as opposed to a sales, receipts or rental tax on any rents or income attributable to operations at the Project), (ii) any items included as Operating Expenses, and (iii) any items paid by Tenant under Section 4.5 of this Lease.

4.2.6 “Tenant’s Share” is based upon the following ratios, as applicable: (i) for the Building, the ratio that the rentable square feet of the Premises bears to the rentable square feet of the Building (i.e., 15,526 ÷ 29,840) and initially shall mean the percentage set forth in Section 7 of the Summary, and (ii) for the Project, the ratio that the rentable square feet of the Premises bears to the rentable square feet of the Project (i.e., 15,526 ÷ 89,471); initially, Tenant’s Share shall mean the applicable percentages set forth in Section 7 of the Summary.

4.3 Allocation of Direct Expenses. The parties acknowledge that the Building is a part of a multi-building project and that the costs and expenses incurred in connection with the Project (i.e., the Direct Expenses) should be shared among the tenants of the Building and the tenants of the other buildings in the Project. Accordingly, as set forth in Section 4.2 above, Direct Expenses (which consist of Operating Expenses and Tax Expenses) are determined annually for the Project as a whole, and a portion of the Direct Expenses, which portion shall be determined by Landlord on an equitable basis, shall be allocated to the tenants of the Building (as opposed to the tenants of any other buildings in the Project). Such portion of Direct Expenses allocated to the tenants of the Building shall include all Direct Expenses attributable solely to the Building and an equitable portion of the Direct Expenses attributable to the Project as a whole. Further, Landlord shall have the right, from time to time, to allocate equitably some or all of the Direct Expenses for the Building or the Project among different portions or occupants of the Building or Project, in Landlord’s reasonable discretion, in a manner reflecting commercially reasonable cost pools for such Direct Expenses so allocated. The Direct Expenses within each cost pool shall be allocated and charged to the tenants within such cost pool in an equitable manner.

4.4 Calculation and Payment of Additional Rent. Tenant shall pay to Landlord, in the manner set forth in Section 4.4.1 below, and as Additional Rent, Tenant’s Share of Direct Expenses for each Expense Year.

4.4.1 Statement of Actual Direct Expenses and Payment by Tenant. Landlord shall endeavor to give to Tenant within six (6) months following the end of each Expense Year, a statement (the “Statement”) which shall state the Direct Expenses incurred or accrued for such preceding Expense Year, and which shall indicate the amount of Tenant’s Share of Direct Expenses. Upon receipt of the Statement for each Expense Year commencing or ending during the Lease Term, Tenant shall pay, with its next installment of Base Rent due, the full amount of Tenant’s Share of Direct Expenses for such Expense Year, less the amounts, if any, paid during such Expense Year as “Estimated Direct Expenses”, as that term is defined in Section 4.4.2 below, and if Tenant paid more as Estimated Direct Expenses than the actual Tenant’s Share of Direct Expenses, Tenant shall receive a credit in the amount of Tenant’s overpayment against Rent next due under this Lease or, if Landlord elects, Landlord shall reimburse such overpayment amount to Tenant. The failure of Landlord to timely furnish the Statement for any Expense Year shall not prejudice Landlord or Tenant from enforcing its rights under this Article 4. Even though the Lease Term has

-10-

expired and Tenant has vacated the Premises, when the final determination is made of Tenant’s Share of Direct Expenses for the Expense Year in which this Lease terminates, Tenant shall pay to Landlord such amount within thirty (30) days, and if Tenant paid more as Estimated Direct Expenses than the actual Tenant’s Share of Direct Expenses, Landlord shall, within thirty (30) days, pay to Tenant the amount of the overpayment. The provisions of this Section 4.4.1 shall survive the expiration or earlier termination of the Lease Term.

4.4.2 Statement of Estimated Direct Expenses. In addition, Landlord shall endeavor to give Tenant a yearly expense estimate statement (the “Estimate Statement”) which shall set forth Landlord’s reasonable estimate (the “Estimate”) of what the total amount of Direct Expenses for the then-current Expense Year shall be and the estimated Tenant’s Share of Direct Expenses (the “Estimated Direct Expenses”). The failure of Landlord to timely furnish the Estimate Statement for any Expense Year shall not preclude Landlord from enforcing its rights to collect any Estimated Direct Expenses under this Article 4, nor shall Landlord be prohibited from revising any Estimate Statement or Estimated Direct Expenses theretofore delivered to the extent necessary. Thereafter, Tenant shall pay, with its next installment of Base Rent due, a fraction of the Estimated Direct Expenses for the then-current Expense Year (reduced by any amounts paid pursuant to the last sentence of this Section 4.4.2). Such fraction shall have as its numerator the number of months which have elapsed in such current Expense Year, including the month of such payment, and twelve (12) as its denominator. Until a new Estimate Statement is furnished (which Landlord shall have the right to deliver to Tenant at any time), Tenant shall pay monthly, with the monthly Base Rent installments, an amount equal to one-twelfth (1/12) of the total Estimated Direct Expenses set forth in the previous Estimate Statement delivered by Landlord to Tenant.

4.5 Taxes and Other Charges for Which Tenant Is Directly Responsible. Tenant shall be liable for and shall pay ten (10) days before delinquency, taxes levied against Tenant’s equipment, furniture, fixtures and any other personal property located in or about the Premises. If any such taxes on Tenant’s equipment, furniture, fixtures and any other personal property are levied against Landlord or Landlord’s property or if the assessed value of Landlord’s property is increased by the inclusion therein of a value placed upon such equipment, furniture, fixtures or any other personal property and if Landlord pays the taxes based upon such increased assessment, which Landlord shall have the right to do regardless of the validity thereof but only under proper protest if requested by Tenant, Tenant shall upon demand (together with reasonable back-up evidencing the same) repay to Landlord the taxes so levied against Landlord or the proportion of such taxes resulting from such increase in the assessment, as the case may be.

4.6 Audit Rights. Tenant shall have the right, at Tenant’s cost, after reasonable notice to Landlord, to have Tenant’s authorized employees or agents inspect, at Landlord’s California office during normal business hours, Landlord’s books, records and supporting documents concerning the Direct Expenses set forth in any statement delivered by Landlord to Tenant for a particular calendar year pursuant to Section 4.4.1 above; provided, however, Tenant shall have no right to conduct such inspection or object to or otherwise dispute the amount of the Direct Expenses set forth in any such statement, unless Tenant notifies Landlord of such inspection request, completes such inspection, and demands an audit as set forth below within six (6) months immediately following Landlord’s delivery of the particular statement in question (the “Review Period”); provided, further, that notwithstanding any such timely inspection, objection, dispute, and/or audit, and as a condition precedent to Tenant’s exercise of its right of inspection, objection, dispute, and/or audit as set forth in this Section 4.6 Tenant shall not be permitted to withhold payment of, and Tenant shall timely pay to Landlord, the full amounts as required by the provisions of this Article 4 in accordance with such statement. However, such payment may be made under protest pending the outcome of any audit. In connection with any such inspection by Tenant, Landlord and Tenant shall reasonably cooperate with each other so that such inspection can be performed pursuant to a mutually acceptable schedule, in an expeditious manner and without undue interference with Landlord’s operation and management of the Project. If after such inspection and/or request for documentation, Tenant disputes the amount of the Direct Expenses set forth in the statement, Tenant shall have the right, but not the obligation, within the Review Period, to cause an independent certified public accountant which is not paid on a contingency basis and which is mutually agreed upon by Landlord and Tenant (the “Accountant”) to complete an audit of Landlord’s books and records to determine the proper amount of the Direct Expenses incurred and amounts payable by Tenant for the calendar year which is the subject of such statement. Such audit by the Accountant shall be final and binding upon Landlord and Tenant. If Landlord and Tenant cannot mutually agree as to the identity of the Accountant within thirty (30) days after Tenant notifies Landlord that Tenant desires an audit to be performed, then the Accountant shall be one of the “Big 4” accounting firms selected by Tenant, which is not paid on a contingency basis. If such audit reveals that Landlord has over-charged Tenant, then within thirty (30) days after the results of such audit are made available to Landlord, Landlord shall reimburse to Tenant the amount of

-11-

such over-charge. If the audit reveals that the Tenant was under-charged, then within thirty (30) days after the results of such audit are made available to Tenant, Tenant shall reimburse to Landlord the amount of such under-charge. Tenant agrees to pay the cost of such audit unless it is subsequently determined that Landlord’s original statement which was the subject of such audit was in error to Tenant’s disadvantage by five percent (5%) or more of the total Direct Expenses which was the subject of such audit (but in such an event, Landlord’s obligation to pay for such audit shall not exceed the sum of $6,000). The payment by Tenant of any amounts pursuant to this Article 4 shall not preclude Tenant from questioning the correctness of any statement provided by Landlord at any time during the Review Period, but the failure of Tenant to object thereto, conduct and complete its inspection and have the Accountant conduct and complete the audit as described above prior to the expiration of the Review Period shall be conclusively deemed Tenant’s approval of the statement in question and the amount of Direct Expenses shown thereon. In connection with any inspection and/or audit conducted by Tenant pursuant to this Section 4.6, Tenant agrees to keep, and to cause all of Tenant’s employees and consultants and the Accountant to keep, all of Landlord’s books and records and the audit, and all information pertaining thereto and the results thereof, strictly confidential (except to the extent disclosure is required in accordance with applicable law), and in connection therewith, Tenant shall cause such employees, consultants and the Accountant to execute such reasonable confidentiality agreements as Landlord may require prior to conducting any such inspections and/or audits.

5. USE OF PREMISES

5.1 Permitted Use. Tenant shall use the Premises solely for the Permitted Use set forth in Section 8 of the Summary and Tenant shall not use or permit the Premises or the Project to be used for any other purpose or purposes whatsoever.

Tenant further covenants and agrees that Tenant shall not use, or suffer or permit any person or persons claiming by, through, or under Tenant to use, the Premises or any part thereof for any use or purpose contrary to the provisions of the Rules and Regulations attached hereto as Exhibit 5.2, as the same may be amended by Landlord from time to time (the “Rules and Regulations”), or in violation of Applicable Laws or any Underlying Documents. Tenant shall not do or permit anything to be done in or about the Premises which will in any way damage the reputation of the Project or obstruct or interfere with the rights of other tenants or occupants of the Building, or injure or annoy them or use or allow the Premises to be used for any improper, unlawful or objectionable purpose, nor shall Tenant cause, maintain or permit any nuisance in, on or about the Premises. Tenant shall comply with, and Tenant’s rights and obligations under the Lease and Tenant’s use of the Premises shall be subject and subordinate to, all Underlying Documents. Tenant shall only place equipment within the Premises with floor loading consistent with the Building’s structural design, and such equipment shall be placed in a location designed to carry the weight of such equipment. Tenant shall cause any equipment or machinery to be installed in the Premises so as to reasonably prevent sounds or vibrations therefrom from extending into the Common Areas or other offices in the Project.

5.3.1 Landlord’s and Tenant’s Obligations.

5.3.1.1 Prohibitions. As a material inducement to Landlord to enter into this Lease with Tenant, Tenant has fully and accurately completed Landlord’s Pre-Leasing Environmental Exposure Questionnaire (the “Environmental Questionnaire”), which is attached as Exhibit 5.3.1.1. Tenant hereby represents, warrants and covenants that except for those chemicals or materials, and their respective quantities, specifically listed on the Environmental Questionnaire, neither Tenant nor Tenant’s subtenants or assigns, or any of their respective employees, contractors and subcontractors of any tier, entities with a contractual relationship with such parties (other than Landlord), or any entity acting as an agent or sub-agent of such parties or any of the foregoing (collectively, “Tenant Parties”) will produce, use, store or generate any “Hazardous Materials”, as that term is defined below, on, under or about the Premises, nor cause or permit any Hazardous Material to be brought upon, placed, stored, manufactured, generated, blended, handled, recycled, used or “Released”, as that term is defined below, on, in, under or about the Premises or Project. If any information provided to Landlord by Tenant on the Environmental Questionnaire, or otherwise relating to information concerning Hazardous Materials is false, incomplete, or misleading in any material respect, the same shall be deemed a default by Tenant under this Lease. Upon Landlord’s request, or in the event of any material change in Tenant’s use of Hazardous Materials at the Premises, Tenant shall deliver to Landlord an updated Environmental Questionnaire. Landlord’s prior written consent shall be required for any Hazardous Materials

-12-

use for the Premises not described on the initial Environmental Questionnaire, such consent not to be unreasonably withheld, conditioned or delayed. Tenant shall not install or permit any underground storage tank on the Premises. In addition, Tenant agrees that it: (i) shall not cause or suffer to occur, the Release (as defined below) of any Hazardous Materials at, upon, under or within the Premises or any contiguous or adjacent premises; and (ii) shall not engage in activities at the Premises that give rise to, or lead to the imposition of, liability upon Tenant or Landlord or the creation of an environmental lien or use restriction upon the Premises. For purposes of this Lease, “Hazardous Materials” means all flammable explosives, petroleum and petroleum products, oil, radon, radioactive materials, toxic pollutants, asbestos, polychlorinated biphenyls (“PCBs”), medical waste, chemicals known to cause cancer or reproductive toxicity, pollutants, contaminants, hazardous wastes, toxic substances or related materials, including without limitation any chemical, element, compound, mixture, solution, substance, object, waste or any combination thereof, which is or may hereafter be determined to be hazardous to human health, safety or to the environment due to its radioactivity, ignitability, corrosiveness, reactivity, explosiveness, toxicity, carcinogenicity, infectiousness or other harmful or potentially harmful properties or effects, or defined as, regulated as or included in, the definition of “hazardous substances”, “hazardous wastes”, “hazardous materials”, or “toxic substances” under any Environmental Laws. The term “Hazardous Materials” for purposes of this Lease shall also include any mold, fungus or spores, whether or not the same is defined, listed, or otherwise classified as a “hazardous material” under any Environmental Laws, if such mold, fungus or spores may pose a risk to human health or the environment or negatively impact the value of the Premises. Hazardous Materials shall also include any “biohazardous waste,” “medical waste,” or other waste under California Health and Safety Code Division 20, Chapter 6.1 (Medical Waste Management Act). For purposes of this Lease, “Release” or “Released” or “Releases” shall mean any release, deposit, discharge, emission, leaking, spilling, seeping, migrating, injecting, pumping, pouring, emptying, escaping, dumping, disposing, or other movement of Hazardous Materials into the environment.

5.3.1.2 Notices to Landlord or Tenant, as Applicable. Unless a party hereto is required by Applicable Laws to give earlier notice to the other, each party shall notify the other in writing as soon as possible but in no event later than five (5) days after (i) the occurrence of any actual, alleged or threatened Release of any Hazardous Material in, on, under, from, about or in the vicinity of the Premises (whether past or present), regardless of the source or quantity of any such Release, or (ii) either party becomes aware of any regulatory actions, inquiries, inspections, investigations, directives, or any cleanup, compliance, enforcement or abatement proceedings (including any threatened or contemplated investigations or proceedings) relating to or potentially affecting the Premises and not in the ordinary course of Tenant’s business, or (iii) either party becomes aware of any claims by any person or entity relating to any Hazardous Materials in, on, under, from, about or in the vicinity of the Premises, whether relating to damage, contribution, cost recovery, compensation, loss or injury. Collectively, the matters set forth in clauses (i), (ii) and (iii) above are hereinafter referred to as “Hazardous Materials Claims”. Tenant shall promptly forward to Landlord copies of all orders, notices, permits, applications and other communications and reports in connection with any Hazardous Materials Claims. Additionally, each party shall promptly advise the other in writing of a discovery of any occurrence or condition on, in, under or about the Premises that could subject Tenant or Landlord to any liability, or restrictions on ownership, occupancy, transferability or use of the Premises under any “Environmental Laws” (as that term is defined below). Neither party shall enter into any legal proceeding or other action, settlement, consent decree or other compromise with respect to any Hazardous Materials Claims without first notifying the other of the intention to do so and affording the other party the opportunity to join and participate, as a party if the other so elects, in such proceedings and in no event shall either party enter into any agreements which are binding on the other without the other’s prior written consent. Each party shall have the right to appear at and participate in, any and all legal or other administrative proceedings concerning any Hazardous Materials Claim.

In the event of any Release of any Hazardous Material in, on, under, from or about the Premises in violation of, or requiring any Clean-Up (as defined below), in addition to notifying the other party as specified above, the party responsible for the Release (with respect to any Release for which either Landlord or Tenant is responsible), at such party’s own sole cost and expense, shall (i) immediately comply with any and all reporting requirements imposed pursuant to any and all Environmental Laws, (ii) provide a written certification to the other indicating that the responsible party has complied with all applicable reporting requirements, (iii) take any and all necessary investigation, corrective, remedial and other Clean-up action in accordance with any and all applicable Environmental Laws, utilizing an environmental consultant reasonably approved by Landlord, all in accordance with the provisions and requirements of this Section 5.3, including, without limitation, Section 5.3.4, and (iv) take any such additional investigative, remedial and corrective actions as Landlord shall in its reasonable discretion deem necessary such that the Premises and Project are remediated to a condition allowing unrestricted use of the Premises (i.e., to a level that will allow any future use of the Premises, including residential, without any engineering controls or deed restrictions), all in accordance with the provisions and requirements of this Section 5.3. Either party may, as required by any and all Environmental Laws, report the Release of any Hazardous Material to the appropriate governmental authority, identifying the responsible party.

Notwithstanding anything in this Section 5.3.1.4 to the contrary, Tenant’s indemnity of Landlord shall not be applicable to claims based upon Existing Hazardous Materials except to the extent that Tenant’s construction activities and/or Tenant’s other acts or omissions caused or exacerbated the subject claim. “Existing Hazardous Materials” shall mean Hazardous Materials located on the Property in violation of applicable Environmental Laws as of the date of this Lease.

-14-

5.3.1.5 Compliance with Environmental Laws. Without limiting the generality of Tenant’s obligation to comply with Applicable Laws as otherwise provided in this Lease, Tenant shall, at its sole cost and expense, comply with all Environmental Laws in its occupancy and operation of the Premises. Tenant shall obtain and maintain any and all necessary permits, licenses, certifications and approvals appropriate or required for the use, handling, storage, and disposal of any Hazardous Materials used, stored, generated, transported, handled, blended, or recycled by Tenant on the Premises. Landlord shall have a continuing right, without obligation, to require Tenant to obtain, and to review and inspect any and all such permits, licenses, certifications and approvals, together with copies of any and all Hazardous Materials management plans and programs, any and all Hazardous Materials risk management and pollution prevention programs, and any and all Hazardous Materials emergency response and employee training programs respecting Tenant’s use of Hazardous Materials. Upon request of Landlord, Tenant shall deliver to Landlord a narrative description explaining the nature and scope of Tenant’s activities involving Hazardous Materials and showing to Landlord’s satisfaction compliance with all Environmental Laws and the terms of this Lease.

5.3.2 Assurance of Performance.

5.3.2.1 Environmental Assessments In General. Landlord may, but shall not be required to, engage from time to time such contractors as Landlord determines to be appropriate to perform “Environmental Assessments”, as that term is defined below, to ensure Tenant’s compliance with the requirements of this Lease with respect to Hazardous Materials. For purposes of this Lease, “Environmental Assessment” means an assessment including, without limitation: (i) an environmental site assessment conducted in accordance with the then-current standards of the American Society for Testing and Materials and meeting the requirements for satisfying the “all appropriate inquiries” requirements; and (ii) sampling and testing of the Premises based upon potential recognized environmental conditions or areas of concern or inquiry identified by the environmental site assessment.

5.3.2.2 Costs of Environmental Assessments. All costs and expenses incurred by Landlord in connection with any such Environmental Assessment initially shall be paid by Landlord; provided that if any such Environmental Assessment shows that Tenant has failed to comply with the provisions of this Section 5.3, then all of the costs and expenses of such Environmental Assessment shall be reimbursed by Tenant as Additional Rent within thirty (30) days after receipt of written demand therefor.

5.3.3 Tenant’s Obligations upon Surrender. At the expiration or earlier termination of the Lease Term, Tenant, at Tenant’s sole cost and expense, shall: (i) cause an Environmental Assessment of the Premises to be conducted in accordance with Section 15.3; (ii) cause all Hazardous Materials to be removed from the Premises and disposed of in accordance with all Environmental Laws and as necessary to allow the Premises to be used for any purpose; and (iii) cause to be removed all containers installed or used by any Tenant Parties to store any Hazardous Materials on the Premises, and cause to be repaired any damage to the Premises caused by such removal.

5.3.4 Clean-up.

5.3.4.1 Environmental Reports; Clean-Up. If any written report, including any report containing results of any Environmental Assessment (an “Environmental Report”) shall indicate (i) the presence of any Hazardous Materials as to which Tenant has a removal or remediation obligation under this Section 5.3, and (ii) that as a result of same, the investigation, characterization, monitoring, assessment, repair, closure, remediation, removal, or other clean-up (the “Clean-up”) of any Hazardous Materials is required, Tenant shall immediately prepare and submit to Landlord within thirty (30) days after receipt of the Environmental Report a comprehensive plan, subject to Landlord’s written approval, specifying the actions to be taken by Tenant to perform the Clean-up so that the Premises are restored to the conditions required by this Lease. Upon Landlord’s approval of the Clean-up plan, Tenant shall, at Tenant’s sole cost and expense, without limitation of any rights and remedies of Landlord under this Lease, immediately implement such plan with a consultant reasonably acceptable to Landlord and proceed to Clean-Up Hazardous Materials in accordance with all applicable laws and as required by such plan and this Lease. If, within thirty (30) days after receiving a copy of such Environmental Report, Tenant fails either (a) to complete such Clean-up, or (b) with respect to any Clean-up that cannot be completed within such 30-day period, fails to proceed with diligence to prepare the Clean-up plan and complete the Clean-up as promptly as practicable, then Landlord shall have the right, but not the obligation, and without waiving any other rights under this Lease, to carry out any Clean-up recommended by the Environmental Report or required by any governmental authority having jurisdiction over the Premises, and recover all of the costs and expenses thereof from Tenant as Additional Rent, payable within ten (10) days after receipt of written demand therefor.

-15-

5.3.4.2 No Rent Abatement. Tenant shall continue to pay all Rent due or accruing under this Lease during any Clean-up for which Tenant is responsible, and shall not be entitled to any reduction, offset or deferral of any Base Rent or Additional Rent due or accruing under this Lease during any such Clean-up.

5.3.4.3 Surrender of Premises. Tenant shall complete any Clean-up for which Tenant is responsible prior to surrender of the Premises upon the expiration or earlier termination of this Lease, and shall fully comply with all Environmental Laws and requirements of any governmental authority with respect to such completion, including, without limitation, fully comply with any requirement to file a risk assessment, mitigation plan or other information with any such governmental authority in conjunction with the Clean-up prior to such surrender. Tenant shall obtain and deliver to Landlord a letter or other written determination from the overseeing governmental authority confirming that the Clean-up has been completed in accordance with all requirements of such governmental authority and that no further response action of any kind is required for the unrestricted use of the Premises (“Closure Letter”). Upon the expiration or earlier termination of this Lease, Tenant shall also be obligated to close all permits obtained in connection with Hazardous Materials in accordance with Applicable Laws.

5.3.4.4 Failure to Timely Clean-Up. Should any Clean-up for which Tenant is responsible not be completed, or should Tenant not receive the Closure Letter and any governmental approvals required under Environmental Laws in conjunction with such Clean-up prior to the expiration or earlier termination of this Lease, and Tenant’s failure to receive the Closure Letter is prohibiting Landlord from leasing the Premises or any part thereof to a third party, or prevents the occupancy or use of the Premises or any part thereof by a third party, then Tenant shall be liable to Landlord as a holdover tenant (as more particularly provided in Article 16) until Tenant has fully complied with its obligations under this Section 5.3.

5.3.5 Confidentiality. Unless compelled to do so by applicable law, Tenant agrees that Tenant shall not disclose, discuss, disseminate or copy any information, data, findings, communications, conclusions and reports regarding the environmental condition of the Premises to any Person (other than Tenant’s consultants, attorneys, property managers and employees that have a need to know such information), including any governmental authority, without the prior written consent of Landlord. In the event Tenant reasonably believes that disclosure is compelled by Applicable Laws, it shall provide Landlord ten (10) days’ advance notice of disclosure of confidential information so that Landlord may attempt to obtain a protective order. Tenant may additionally release such information to bona fide prospective purchasers or lenders, subject to any such parties’ written agreement to be bound by the terms of this Section 5.3.

5.3.6 Copies of Environmental Reports. Within thirty (30) days of receipt thereof, Tenant shall provide Landlord with a copy of any and all environmental assessments, audits, studies and reports regarding Tenant’s activities with respect to the Premises, or ground water beneath the Land, or the environmental condition or Clean-up thereof. Tenant shall be obligated to provide Landlord with a copy of such materials without regard to whether such materials are generated by Tenant or prepared for Tenant or how Tenant comes into possession of such materials.

5.3.7 Signs, Response Plans, Etc. Tenant shall be responsible for posting on the Premises any signs required under applicable Environmental Laws. Tenant shall also complete and file any business response plans or inventories required by any applicable Environmental Laws. Tenant shall concurrently file a copy of any such business response plan or inventory with Landlord.

5.3.8 Survival. Each covenant, agreement, representation, warranty and indemnification made by the parties set forth in this Section 5.3 shall survive the expiration or earlier termination of this Lease and shall remain effective until all obligations under this Section 5.3 have been completely performed and satisfied.

5.4 Premises Compliance with ADA. Notwithstanding any other provision herein to the contrary, and except to the extent any non-compliance is determined by a condition or feature of the Common Area or the Building rather than the condition of the Premises, Tenant shall be responsible for all liabilities, costs and expenses arising out of or in connection with non-compliance of the Premises with the Americans with Disabilities Act, 42 U.S.C. § 1210

-16-

I, et seq., and any state and local accessibility laws, codes, ordinances and rules (collectively, and together with regulations promulgated pursuant thereto, the “ADA”), arising out of Tenant alterations of the Premises either in connection with the construction of the Work Letter Tenant Improvements or after completion of the Work Letter Tenant Improvements, and Tenant shall indemnify, save, defend (at Landlord’s option and with counsel reasonably acceptable to Landlord) and hold Landlord and its affiliates, employees, agents and contractors; and any lender, mortgagee or beneficiary (each, a “Lender” and, collectively with Landlord its partners and subpartners, and their respective officers, members, directors, shareholders, agents, property managers, employees and independent contractors, the “Landlord Indemnitees”) harmless from and against any demands, claims, liabilities, losses, costs, expenses, actions, causes of action, damages or judgments, and all reasonable expenses (including reasonable attorneys’ fees, charges and disbursements) incurred in investigating or resisting the same (collectively, “Claims”) arising out of any such failure of the Premises to comply with the ADA. To the extent any non-compliance is determined by a condition or feature of the Building Common Areas or Project Common Areas, Landlord shall be responsible for all liabilities, costs and expenses arising out of or in connection with any compliance work in order to correct any non-compliance with the ADA arising out of Landlord’s alterations of the Building Common Areas and Project Common Areas. The provisions of this Section shall survive the expiration or earlier termination of this Lease.

5.5 Rules and Regulations, CC&Rs, Parking Facilities and Common Areas.

5.5.1 Tenant shall have the non-exclusive right, in common with others, to use the Common Areas, subject to the Rules and Regulations. The he Common Areas shall be maintained and operated by Landlord in a neat, clean, and orderly condition consistent with a first class office park, and the use thereof shall be subject to the commercially reasonable Rules and Regulations, as Landlord may make from time to time.

5.5.2 This Lease is subject to any recorded covenants, conditions or restrictions on the Project or Property (the “CC&Rs”), as the same may be amended, amended and restated, supplemented or otherwise modified from time to time; provided that any such amendments, restatements, supplements or modifications do not materially modify Tenant’s rights or obligations hereunder. Tenant shall comply with any such CC&Rs.

5.5.3 Tenant shall have a non-exclusive, irrevocable license to use throughout the Lease Term the number of unreserved parking passes set forth in Section 2.11 of the Summary in at such locations in the parking facilities serving the Building as may be determined by Landlord from time to time in common with the other occupants of the Building, on an unreserved basis, at no cost to Tenant. Tenant shall use only such parking facilities to park Tenant’s vehicles. In no event shall Tenant park or store any items other than automotive vehicles at such parking facilities.

5.5.4 Tenant agrees not to unreasonably overburden the parking facilities and agrees to cooperate with Landlord and other tenants in the use of the parking facilities. Landlord reserves the right to determine that parking facilities are becoming overcrowded and to limit Tenant’s use thereof. Landlord may reasonably allocate parking spaces among Tenant and other tenants of the Building or the Project and Tenant shall be entitled to use throughout the Lease Term the number of unreserved parking passes set forth in Section 2.11 of the Summary. Nothing in this Section, however, is intended to create an affirmative duty on Landlord’s part to monitor parking.

5.5.5 Landlord reserves the right to modify the Common Areas, including the right to add or remove exterior and interior landscaping and to subdivide real property, in accordance with the terms and conditions of this Lease. Tenant acknowledges that Landlord specifically reserves the right to allow the exclusive use of corridors and restroom facilities located on specific floors to one or more tenants occupying such floors; provided, however, that Tenant shall not be deprived of the use of the corridors reasonably required to serve the Premises or of restroom facilities serving the floor upon which the Premises are located. Landlord reserves the right to close temporarily, make alterations or additions to, or change the location of elements of the Project and the Common Areas in a commercially reasonable manner that does not interfere with Tenant’s use and enjoyment of the Premises

Tenant shall bear the cost of replacement of lamps, starters and ballasts for non-Building standard lighting fixtures within the Premises.

6.1.3 Landlord shall provide city water from the regular Building outlets for drinking, lavatory and toilet purposes in the Building Common Areas.

6.1.5 Landlord agrees to provide and maintain utility connections to the Building and, where applicable, Common Areas, for electricity, water and sewer.

6.1.6 Subject to the provisions of this Article, Landlord shall furnish the electric energy that Tenant shall reasonably require in the Premises for the purposes permitted under this Lease. Except for electric energy required to operate motors on the air handlers providing HVAC (the “HVAC Electric”), such electric energy shall be furnished through a meter or meters and related equipment installed, serviced, maintained, monitored and, as appropriate from time to time, upgraded by Landlord, in each case at Tenant’s expense, measuring the amount of electric energy furnished to the Premises; provided, however, that Landlord shall pay for the cost of installing any such new meters for the Premises. Tenant shall pay for electric energy (for which it is liable for payment under this Article) in accordance with Sections 15.1 and 15.10 within ten (10) days after receipt of any bills related thereto. The amount charged for electric energy furnished to the Premises, excluding HVAC Electric, shall be one hundred percent (100%) of Landlord’s cost (including those charges applicable to or computed on the basis of electric consumption, demand and hours of use, any sales or other taxes regularly passed on to Landlord by such public utility company, fuel rate adjustments and surcharges, weighted in each case to reflect differences in consumption or demand applicable to each rate level). Tenant and its authorized representatives may have access to such meter or meters (if any) on at least three (3) days’ prior notice to Landlord for the purpose of verifying Landlord’s meter readings (if any). From time to time during the Lease Term, Landlord may, in its sole discretion, (a) install or eliminate such meters, (b) increase or reduce the number of such meters, (e) vary the portions of the Premises that such meters serve or (d) replace any or all of such meters.

6.1.7 Landlord shall provide janitorial and office trash services and other cleaning of the Premises. The janitorial and cleaning of the Premises shall be adequate to maintain the Premises in a manner consistent with Comparable Buildings.

6.2.1 Subject to Applicable Laws and the other provisions of this Lease (including, without limitation, the Rules and Regulations, and except in the event of an emergency) and Landlord’s reasonable security measures, Tenant shall have access to the Building, the Premises and the Common Areas of the Building, other than Common Areas requiring access with a Building engineer, twenty-four (24) hours per day, seven (7) days per week, every day of the year; provided, however, that Tenant shall only be permitted to have access to and use of the limited-access areas of the Building during the normal operating hours of such portions of the Building.

-18-

Tenant shall cooperate fully with Landlord at all times and abide by all regulations and requirements that Landlord may reasonably prescribe for the proper functioning and protection of the HVAC, electrical, mechanical and plumbing systems.

6.2.2 Tenant shall pay for all water (including the cost to service, repair and replace reverse osmosis, de-ionized and other treated water), gas, heat, light, power, telephone, internet service, cable television, other telecommunications and other utilities supplied to the Premises, together with any fees, surcharges and taxes thereon, utilities and services provided to the Premises that are separately metered shall be paid by Tenant directly to the supplier of such utility or service. If any such utility is not separately metered to Tenant, Tenant shall pay Tenant’s Share of all charges of such utility jointly metered with other premises as Additional Rent or, in the alternative, Landlord may, at its option, monitor the usage of such utilities by Tenant and charge Tenant with the cost of monitoring such metering equipment, provided that Landlord shall pay for the cost of the initial purchase and installation (only) of any such metering equipment. To the extent that Tenant uses more than Tenant’s Pro Rata Share of any utilities, then Tenant shall pay Landlord Tenant’s Share of Operating Expenses to reflect such excess. In the event that the Building or the Project is less than fully occupied, Tenant acknowledges that Landlord may extrapolate utility usage that vary depending on the occupancy of the Building or Project, as applicable, by dividing (a) the total cost of utility usage by (b) the Rentable Area of the Building or Project (as applicable) that is occupied, then multiplying (y) the resulting quotient by (z) ninety-five percent (95%) of the total Rentable Area of the Building or Project (as applicable). Tenant shall pay Tenant’s Share of the product of (y) and (z), subject to adjustment based on actual usage as reasonably determined by Landlord; provided, however, that Landlord shall not recover more than one hundred percent (100%) of such utility costs.

6.2.3 For the Premises, Tenant shall (a) maintain and operate the heating, ventilating and air conditioning systems used for the Permitted Use only (“HVAC”) and (b) subject to clause (a) above, furnish HVAC as reasonably required (except as this Lease otherwise provides) for reasonably comfortable occupancy of the Premises twenty-four (24) hours a day, every day during the Lease Term, subject to casualty, eminent domain or as otherwise specified in this Article. Notwithstanding anything to the contrary in this Section, Landlord shall have no liability, and Tenant shall have no right or remedy, on account of any interruption or impairment in HVAC services for which Tenant is responsible.. If requested in writing by Landlord, Tenant shall provide Landlord copies of HVAC maintenance contracts and HVAC maintenance reports on a quarterly basis. In the event Landlord determines that Tenant is not properly maintaining the HVAC, Landlord may take over the responsibilities in (a) and (b) above.

6.2.4 For any utilities serving the Premises for which Tenant is billed directly by such utility provider, Tenant agrees to furnish to Landlord (a) any invoices or statements for such utilities within thirty (30) days after Tenant’s receipt thereof and (b) within thirty (30) days after Landlord’s request, any other utility usage information reasonably requested by Landlord. Tenant shall retain records of utility usage at the Premises, including invoices and statements from the utility provider, for at least sixty (60) months, or such other shorter period of time as may be requested by Landlord. Tenant acknowledges that any utility information for the Premises, the Building and the Project may be shared with third parties, including Landlord’s consultants and Governmental Authorities. In the event that Tenant fails to comply with this Section, Tenant hereby authorizes Landlord to collect utility usage information directly from the applicable utility providers.

6.2.5 Tenant, at its sole cost, shall furnish and install all replacement lighting tubes, lamps, bulbs and ballasts required in the Premises.

6.2.6 Tenant’s use of electric energy in the Premises shall not at any time exceed the capacity of any of the electrical conductors and equipment in or otherwise serving the Premises. In order to ensure that such capacity is not exceeded, and to avert a possible adverse effect upon the Project’s distribution of electricity via the Project’s electric system, Tenant shall not, without Landlord’s prior written consent in each instance (which consent Landlord may condition upon the availability of electric energy in the Project as allocated by Landlord to various areas of the Project) connect any fixtures, appliances or equipment (other than normal business machines) to the Building’s or Project’s electric system or make any alterations or additions to the electric system of the Premises existing on the date hereof. Should Landlord grant such consent, all additional risers, distribution cables or other equipment required

-19-

therefor shall be provided by Landlord and the cost thereof shall be paid by Tenant to Landlord on demand (or, at Tenant’s option, shall be provided by Tenant pursuant to plans and contractors approved by Landlord, and otherwise in accordance with the provisions of this Lease). Landlord shall have the right to require Tenant to pay sums on account of such cost prior to the installation of any such risers or equipment.

6.2.7 Landlord reserves the right, upon reasonable, prior written notice to Tenant absent exigent circumstances in which the giving of such notice is not reasonably possible, to stop service of the elevator, plumbing, ventilation, air conditioning and electric systems, when Landlord deems reasonably necessary, due to accident, emergency or the need to make repairs, alterations or improvements, until such repairs, alterations or improvements shall have been completed, and subject to Section 6.4 below, Landlord shall further have no responsibility or liability for failure to supply elevator facilities, plumbing, ventilation, air conditioning or electric service when prevented from doing so by Force Majeure; a failure by a third party to deliver gas, oil or another suitable fuel supply; or Landlord’s inability by exercise of reasonable diligence to obtain gas, oil or another suitable fuel. If any such repairs, alterations or improvements might require or cause an interruption in electrical service to the Premises or any portion thereof, Landlord will give to Tenant at least three (3) business days prior written notice whenever practicable. Without limiting the foregoing, it is expressly understood and agreed that any covenants on Landlord’s part to furnish any service pursuant to any of the terms, covenants, conditions, provisions or agreements of this Lease, or to perform any act or thing for the benefit of Tenant, shall not be deemed breached if Landlord is unable to furnish or perform the same by virtue of Force Majeure.

6.3 Capacities; Overstandard Tenant Use. If Tenant uses water, electricity, heat or air conditioning in excess of that supplied by Landlord pursuant to Section 6.1 of this Lease, Tenant shall pay to Landlord, within thirty (30) days after Tenant’s receipt of an invoice therefor, the actual cost of such excess consumption; and if Tenant does not cease such excessive usage promptly following written notice from Landlord, Landlord may install devices to separately meter any utility use (or use other reasonable industry standard methods to reasonably estimate such use) and in such event Tenant shall pay the cost directly to Landlord, within thirty (30) days after Tenant’s receipt of an invoice therefor, at the rates charged by the public utility company furnishing the same, including the cost of installing, testing and maintaining of such additional metering devices. Tenant’s use of electricity and any other utility serving the Premises shall never exceed the capacity of the feeders to the Project or the risers or wiring installation or Tenant’s Share of the per floor limits for such usage. If Tenant desires to use heat, ventilation or air conditioning during hours other than those for which Landlord is obligated to supply such utilities pursuant to the terms of Section 6.1 of this Lease, Tenant shall give Landlord such prior notice, if any, as Landlord shall from time to time establish as appropriate, of Tenant’s desired use in order to supply such utilities, and Landlord shall supply such utilities to Tenant at such hourly cost per zone to Tenant (which shall be treated as Additional Rent) as Landlord shall from time to time establish based upon its reasonably estimated out-of-pocket costs.

6.4 Interruption of Use. Tenant agrees that, to the extent permitted pursuant to Applicable Laws, Landlord shall not be liable for damages, by abatement of Rent (except as expressly set forth below) or otherwise, for failure to furnish or delay in furnishing any service required to be provided by Landlord pursuant to Section 6.1 of this Lease, or for any diminution in the quality or quantity thereof, when such failure or delay or diminution is occasioned, in whole or in part, by breakage, repairs, replacements or improvements, by any strike, lockout or other labor trouble, by inability to secure electricity, gas, water, or other fuel at the Building or Project after reasonable effort to do so, by any riot or other dangerous condition, emergency, accident or casualty not caused by Landlord, or by act or default of Tenant or other parties; and such failures or delays or diminution shall never be deemed to constitute an eviction or disturbance of Tenant’s use and possession of the Premises or relieve Tenant from paying Rent or performing any of its obligations under this Lease. Furthermore, Landlord shall not be liable under any circumstances for a loss of, or injury to, property or for injury to, or interference with, Tenant’s business, including, without limitation, loss of profits, however occurring, through or in connection with or incidental to a failure to furnish any of the services or utilities as set forth in this Article 6. Notwithstanding the foregoing to the contrary, in the event that there shall be an interruption, curtailment or suspension of any service required to be provided by Landlord pursuant to Section 6.1 of this Lease (and no reasonably equivalent alternative service or supply is provided by Landlord) that shall materially interfere with Tenant’s use and enjoyment of a material portion of the Premises, and Tenant actually ceases to use the affected portion of the Premises (any such event, a “Service Interruption”), and if (i) such Service Interruption shall continue for seven (7) consecutive business days following receipt by Landlord of written notice from Tenant describing such Service Interruption (the “Service Interruption Notice”), and (ii) such Service Interruption shall not have been caused, in whole or in part, by reasons beyond Landlord’s reasonable control

-20-

or by an act or omission in violation of this Lease by any Tenant Party or by any negligence of Tenant any Tenant Parties (a Service Interruption that satisfies the foregoing conditions being referred to hereinafter as a “Material Service Interruption”), then, as liquidated damages and Tenant’s sole remedy at law or equity, Tenant shall be entitled to an equitable abatement of Base Rent and Tenant’s Share of Direct Expenses, based on the nature and duration of the Material Service Interruption, the area of the Premises affected, and the then current Rent amounts, for the period that shall begin on the commencement of such Material Service Interruption and that shall end on the day such Material Service Interruption ceases. Landlord shall use commercially reasonable efforts (i) to limit the duration of any such Service Interruption, and (ii) to mitigate, to the extent reasonably practicable under the circumstances, the interference with Tenant’s use and enjoyment of the affected portion of the Premises. To the extent a Material Service Interruption is caused by an event covered by Articles 11 or 13 of this Lease, then Tenant’s right to abate rent shall be governed by the terms of such Article 11 or 13, as applicable, and the provisions of this paragraph shall not apply.

6.5 Triple Net Lease. Landlord and Tenant acknowledge that, except as otherwise provided to the contrary in this Lease, it is their intent and agreement that this Lease be a “TRIPLE NET” lease and that as such, the provisions contained in this Lease are intended to pass on to Tenant or reimburse Landlord for the costs and expenses reasonably associated with this Lease, and those of the Building and the Project allocable to the Premises, and Tenant’s operation therefrom except as expressly described herein. To the extent such costs and expenses payable by Tenant cannot be charged directly to, and paid by, Tenant, such costs and expenses shall be paid by Landlord but reimbursed by Tenant as Additional Rent.

7. REPAIRS

Tenant shall, at Tenant’s own expense, keep the Premises, including all improvements, fixtures, furnishings, and systems and equipment within the Premises or elsewhere exclusively serving the Premises, in good order, repair and condition at all times during the Lease Term. In addition, Tenant shall, at Tenant’s own expense, but under the supervision and subject to the prior reasonable approval of Landlord, and within any reasonable period of time specified by Landlord, promptly and adequately repair all damage to the Premises and replace or repair all damaged, broken, or worn fixtures and appurtenances, except for damage caused by ordinary wear and tear; provided however, that if Tenant fails to make such repairs within applicable notice and cure periods, Landlord may, but need not, make such repairs and replacements, and Tenant shall pay Landlord the cost thereof, including a management fee of 5% of such costs. Without limitation, Tenant shall be responsible for electrical, plumbing, heating, ventilating and air-conditioning systems and other utility services serving the Premises from the Building connection point to the Premises (to the extent serving Tenant exclusively), and Tenant shall secure, pay for, and keep in force contracts with appropriate and reputable service companies reasonably approved by Landlord providing for the regular maintenance of such systems. Notwithstanding the foregoing, Landlord shall be responsible for repairs to the exterior walls, foundation and roof (including roof membrane) of the Building, the structural portions of the floors of the Building, and the base building systems and equipment of the Building and Common Areas (to the extent not serving Tenant exclusively), except to the extent that such repairs are required due to the negligence or willful misconduct of Tenant; provided, however, that if such repairs are due to the negligence or willful misconduct of Tenant, Landlord shall nevertheless make such repairs at Tenant’s expense, or, if covered by Landlord’s insurance, Tenant shall only be obligated to pay any deductible in connection therewith. Subject to the terms of Article 27 below, Landlord may, but shall not be required to, enter the Premises at all reasonable times and upon reasonable prior notice to make such repairs, alterations, improvements or additions to the Premises or to the Project or to any equipment located in the Project as Landlord shall desire or deem necessary or as Landlord may be required to do by governmental or quasi-governmental authority or court order or decree. Tenant hereby waives and releases its right to make repairs at Landlord’s expense under Sections 1941 and 1942 of the California Civil Code or under any similar law, statute or ordinance now or hereafter in effect. Tenant’s obligation hereunder shall include maintenance and repair of all telecommunications wire and cabling with the Building’s network cabling.

8. ADDITIONS AND ALTERATIONS

8.1 Landlord’s Consent to Alterations. Tenant may not make any improvements, alterations, additions or changes to the Premises or any mechanical, plumbing, HVAC facilities or other utility or Building systems pertaining to the Premises (collectively, the “Alterations”) without first procuring the prior written consent of Landlord to such Alterations, which consent shall be requested by Tenant not less than fifteen (15) business days prior to the commencement thereof. Landlord shall not unreasonably withhold or delay its consent to any proposed nonstructural Alterations, provided that such Alterations (1) are not visible from the outside of the Building, (2) do

-21-

not affect the use of or require access to any part of the Building other than the Premises, (3) do not do not violate any certificate of occupancy for the Building or any other permits or licenses relating to the Project, (4) do not adversely affect any service required to be furnished to Tenant or to any other tenant or occupant of the Building, (5) do not affect any Building systems or Common Areas, (6) do not reduce the value or utility of the Building, and (7) otherwise comply with the Rules and Regulations and this Article 8. Prior to commencing any Alterations affecting air distribution or disbursement from ventilation systems serving Tenant or the Building, including without limitation the installation of Tenant’s exhaust systems, Tenant shall provide Landlord with a third party report from a consultant, and in a form reasonably acceptable to Landlord, showing that such work will not adversely affect the ventilation systems or air quality of the Building (or of any other tenant in the Building) and shall, upon completion of such work, provide Landlord with a certification reasonably satisfactory to Landlord from such consultant confirming that no such adverse effects have resulted from such work.

8.2 Manner of Construction. Landlord may impose, as a condition of its consent to any and all Alterations or repairs of the Premises or about the Premises, such requirements as Landlord in its reasonable discretion may deem desirable, including, but not limited to, the requirement that Tenant utilize for such purposes only contractors, subcontractors, materials, mechanics and materialmen selected by Tenant and approved by Landlord (which approval shall not be unreasonably withheld, conditioned or delayed) and the requirement that upon Landlord’s request (subject to the terms of Section 8.5, below), Tenant shall, at Tenant’s expense, remove such Alterations upon the expiration or any early termination of the Lease Term. Tenant shall construct such Alterations and perform such repairs in a good and workmanlike manner, in conformance with any and all Applicable Laws and, where required by Applicable Law, pursuant to a valid building permit. Tenant shall not use (and upon notice from Landlord shall cease using) contractors, services, workmen, labor, materials or equipment that, in Landlord’s reasonable judgment, would disturb labor harmony with the workforce or trades engaged in performing other work, labor or services in or about the Building or the Common Areas. Upon completion of any Alterations (or repairs), Tenant shall deliver to Landlord final lien waivers from all contractors, subcontractors, design professionals, service providers, suppliers and materialmen who performed such work and whose labor, supplies or services give rise to a lien under California law. In addition to Tenant’s obligations under Article 9 of this Lease, upon completion of any Alterations, Tenant shall deliver to the Project construction manager a reproducible copy of the “as built” drawings of the Alterations in CAD format as well as copies of all permits, approvals and other documents issued by any governmental agency in connection with the Alterations.

8.3 Payment for Improvements. Except as otherwise expressly provided to the contrary herein, if Tenant orders any work directly from Landlord, Tenant shall pay to Landlord an amount equal to five percent (5%) of the cost of such work to compensate Landlord for all overhead, general conditions, fees and other costs and expenses arising from Landlord’s involvement with such work. If Tenant does not order any work directly from Landlord, Tenant shall reimburse Landlord for Landlord’s reasonable, actual, out-of-pocket costs and expenses actually incurred in connection with Landlord’s review of any proposed Alterations.

8.4 Construction Insurance. In addition to the requirements of Article 10 of this Lease, in the event that Tenant makes any Alterations, prior to the commencement of such Alterations, Tenant shall provide Landlord with evidence that Tenant or Tenant’s general contractor carries “Builder’s All Risk” insurance (to the extent that the cost of the work shall exceed $100,000.00) in an amount approved by Landlord covering the construction of such Alterations, and such other insurance as Landlord may reasonably require, it being understood and agreed that all of such Alterations shall be insured by Tenant pursuant to Article 10 of this Lease immediately upon completion thereof. In addition, Tenant’s contractors and subcontractors shall be required to carry Commercial General Liability Insurance, Auto Liability Insurance, and Workers’ Compensation Insurance in amounts approved by Landlord and otherwise in accordance with the requirements of Article 10 of this Lease and such Commercial General Liability and Auto Liability insurance shall name Tenant and the Landlord Parties (as defined below) as additional insureds on a primary and non-contributory basis for both ongoing and completed operations. Tenant shall maintain and require its contractors and subcontractors to maintain products-completed operations coverage for not less than the greater of ten (10) years after substantial completion of any Alterations or the greater time under which a claim may be properly brought under the applicable statute of limitations or repose. Landlord may, in its discretion, require Tenant to obtain and record a statutory form of lien bond, or obtain performance and payment bonds, or some alternate form of security satisfactory to Landlord in an amount sufficient to ensure the lien-free completion of such Alterations and naming Landlord as a co-obligee, in each case in form and substance reasonably satisfactory to Landlord. In addition, Tenant’s contractors and subcontractors shall be required to provide a waiver of subrogation in favor of Tenant and the Landlord Parties.

-22-

8.5 Landlord’s Property. All Alterations, improvements, fixtures, equipment and/or appurtenances which may be installed or placed in or about the Premises, from time to time, shall be at the sole cost of Tenant and shall be and become the property of Landlord and remain in place at the Premises following the expiration or earlier termination of this Lease. Notwithstanding the foregoing to the contrary, Landlord may, by written notice to Tenant, require Tenant, at Tenant’s expense, to remove any Alterations and/or improvements and/or systems and equipment within the Premises and to repair any damage to the Premises and Building caused by such removal and return the affected portion of the Premises to a building standard tenant improved condition as determined by Landlord. If Tenant fails to complete any required removal and/or to repair any damage caused by the removal of any Alterations and/or improvements and/or systems and equipment in the Premises and return the affected portion of the Premises to a building standard tenant improved condition as reasonably determined by Landlord, Landlord may do so and may charge the actual and reasonable cost thereof to Tenant. Tenant hereby protects, defends, indemnifies and holds Landlord harmless from any liability, cost, obligation, expense or claim of lien in any manner relating to the installation, placement, removal or financing of any such Alterations, improvements, fixtures and/or equipment in, on or about the Premises, which obligations of Tenant shall survive the expiration or earlier termination of this Lease.

9. COVENANT AGAINST LIENS

Within ten (10) business days following a request in writing by Landlord, Tenant shall keep the Project and Premises free from any liens or encumbrances arising out of the work performed, materials or services furnished or obligations incurred by or on behalf of Tenant (which expressly excludes the Landlord Work), and shall protect, defend, indemnify and hold Landlord harmless from and against any claims, liabilities, judgments or costs (including, without limitation, reasonable attorneys’ fees and costs) arising out of same or in connection therewith. Tenant shall give Landlord notice at least twenty (20) days prior to the commencement of any work, services or obligations related to the Premises giving rise to any such liens or encumbrances (or such additional time as may be necessary under Applicable Laws) to afford Landlord the opportunity of posting and recording appropriate notices of non-responsibility (to the extent applicable pursuant to then Applicable Laws). Tenant shall remove any such lien or encumbrance by statutory lien bond or otherwise within ten (10) business days after notice by Landlord, and if Tenant shall fail to do so, Landlord may pay the amount necessary to remove such lien or encumbrance, without being responsible for investigating the validity thereof.

10. INSURANCE

10.1 Indemnification and Waiver. To the maximum extent permitted pursuant to Applicable Laws, Tenant hereby assumes all risk of damage to property or injury to persons in, upon or about the Premises from any cause whatsoever (including, but not limited to, any personal injuries resulting from a slip and fall in, upon or about the Premises) and agrees that, to the extent permitted pursuant to Applicable Laws, Landlord, its lenders, partners, subpartners, the Additional Insureds, and each of their respective officers, agents, servants, employees, and independent contractors (collectively, “Landlord Parties”) shall not be liable for, and are hereby released from any responsibility for, any damage either to person or property or resulting from the loss of use thereof, which damage is sustained by Tenant or by other persons claiming through Tenant. Tenant shall indemnify, defend, protect, and hold harmless the Landlord Parties from any and all loss, cost, damage, injury, expense and liability (including without limitation court costs and reasonable attorneys’ fees) during the Lease Term, or any period of Tenant’s occupancy of the Premises prior to the commencement or after the expiration of the Lease Term, incurred in connection with or arising from (i) any cause in, on or about the Premises (including, but not limited to, a slip and fall), provided that the terms of the foregoing indemnity shall not apply to the extent of any negligence or willful misconduct of Landlord, (ii) any negligent acts or omissions of Tenant or of any person claiming by, through or under Tenant, or of the contractors, agents, servants, employees, invitees, guests or licensees of Tenant or any such person, in, on or about the Project, or (iii) any breach of the terms of this Lease by Tenant, either prior to, during, or after the expiration of the Lease Term. Should Landlord be named as a defendant in any suit brought against Tenant in connection with or arising out of Tenant’s occupancy of the Premises, Tenant shall pay to Landlord its reasonable costs and expenses incurred in such suit, including without limitation, its actual professional fees such as reasonable appraisers’, accountants’ and attorneys’ fees. Subject to the waiver of subrogation contained herein, Landlord shall indemnify, defend, protect, and hold harmless Tenant and its officers, agents, servants, employees, and independent contractors from any and all loss, cost, damage, injury, expense and liability (including without limitation court costs and reasonable attorneys’ fees) during the Lease Term incurred in connection with or arising from the gross negligence or willful misconduct of Landlord or any Landlord Party. The provisions of this Section 10.1 shall survive the expiration or sooner termination of this Lease.

10.2 Tenant’s Compliance With Landlord’s Property Insurance. Tenant shall, at Tenant’s expense, comply with all insurance company requirements pertaining to the use of the Premises. If Tenant’s conduct or use of the Premises for any purpose other than customary, general office use causes any increase in the premium for such insurance policies then Tenant shall reimburse Landlord for any such increase. Tenant, at Tenant’s expense, shall comply with all rules, orders, regulations or requirements of the American Insurance Association (formerly the National Board of Fire Underwriters) and with any similar body.

10.3 Tenant’s Insurance. Tenant shall maintain, at its sole cost and expense, the following coverages with limits of not less than the greater of (i) those set forth hereunder, (ii) those evidenced on the declaration page of the pertinent insurance policy, and (iii) those required by law.

Such insurance shall be written on an “all risks” of physical loss or damage basis, for the full replacement cost value (subject to reasonable deductible amounts) new without deduction for depreciation of the covered items and in amounts that meet any co-insurance clauses of the policies of insurance and shall include coverage for damage or other loss caused by fire or other peril including, but not limited to, hail, windstorm, flood, earthquake, terrorism, vandalism and malicious mischief, theft, water damage of any type, including sprinkler leakage, earthquake sprinkler leakage, bursting or stoppage of pipes, and explosion.

-24-

10.3.6 Umbrella and/or Excess Liability Insurance policy in excess of Commercial General Liability, Auto Liability, and Employer’s Liability Insurance policies, concurrent to, and at least as broad as the underlying primary insurance policies, which must “drop down” over reduced or exhausted aggregate limits as to such underlying policies and contain a “follow form” statement. The limits must be no less than $5,000,000 each occurrence and $5,000,000 in the aggregate. Such Umbrella/Excess Liability policy must be endorsed to provide that this insurance is primary to, and non-contributory with, any other insurance on which the Additional Insureds are an insured, whether such other insurance is primary, excess, contingent, self-insurance, or insurance on any other basis. This endorsement must cause the Umbrella/Excess coverage to be vertically exhausted, whereby such coverage is not subject to any “Other Insurance” clause under this Umbrella and/or Excess Liability policy.

10.3.7 Tenant’s Agents/Contractors. In the case of Tenant’s contractors, subcontractors, and any vendors/consultants brought on to the property for any Alterations or other Tenant Improvements (collectively, for purposes of this Article 10, Tenant’s “Third Parties”), Tenant shall cause such Third Parties to obtain and maintain such insurance as is required under Sections 10.3.1, 10.3.4, and 10.3.5 herein, unless granted written approval from Landlord to waive such requirements. Such Third Parties’ coverage under Sections 10.3.1 and 10.3.4 shall include Tenant and the Additional Insureds each as additional insureds on a primary and non-contributory basis for both ongoing and completed operations. Additionally, the commercial general liability limit required to be carried by any contractor or subcontractors of Tenant shall be not less than the following: (x) general contractors – $5,000,000, (y) any subcontractors for work costing $250,000 or more – $2,000,000, and (z) any subcontractors for work costing less than $250,000 – $1,000,000. The foregoing limits may be satisfied by a combination of primary and/or excess policies.

10.4 Form of Policies. The minimum limits of policies of insurance required of Tenant and its agents/contractors under this Lease shall in no event limit the liability of Tenant under this Lease. Such insurance shall (i) name Landlord, its subsidiaries and affiliates, Longfellow Property Management Services CA Inc.; San Diego Sycamore Holdings, LLC; San Diego Sycamore REIT, LLC; Longfellow Strategic Value Fund, LLC; LSVF Americas, LP; LSVF Pacific, LP; Longfellow Capital Partners II, LP; Longfellow Real Estate Partners, LLC; Invesco CMI Investments, LP; and any other party the Landlord so specifies (collectively, the “Additional Insureds”), as additional insureds under the policies listed in Sections 10.3.1, 10.3.2, 10.3.4 and 10.3.6. All insurance policies required to be maintained by Tenant shall (i) be issued by an insurance company having a rating of not less than A:VIII in Best’s Insurance Guide or which is otherwise acceptable to Landlord and licensed to do business in the State of California; (ii) be primary insurance as to all claims thereunder and provide that any insurance carried by the Additional Insureds is excess and is non-contributing with any insurance required of Tenant; (iii) be in form and content reasonably acceptable to Landlord (Tenant shall provide full and complete copies of any policies that Landlord reasonably requests); (iv) be endorsed with waiver of subrogation endorsements in favor of the Additional Insureds; (v) not contain deductible or self-insured retention in excess of $25,000 unless otherwise approved by Landlord in writing; and (vi) provide that said insurer shall provide thirty (30) days’ written notice to Landlord and any mortgagee of Landlord, to the extent such names are furnished to Tenant prior to the cancellation of such policy (ten (10) days’ for non-payment of premium). Tenant shall deliver said policy or policies and certificates thereof to Landlord on or before the earlier to occur of (A) the Commencement Date, and (B) the date upon which Tenant is first provided access to the Premises, and at least ten (10) days before the expiration dates thereof. In the event Tenant shall fail to procure such insurance, or to deliver such policies or certificate within ten (10) days after written notice from Landlord, Landlord may, at its option, procure such policies for the account of Tenant, and the cost thereof shall be paid to Landlord within five (5) days after delivery to Tenant of bills therefor. Landlord and the Additional Insureds will not be responsible for any deductibles or self-insured retentions related to any insurance under this Article 10.

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

-25-

10.6 Additional Insurance Obligations. Landlord reserves the right to require such other insurance, written in such other amounts, terms, and conditions, against other insurable hazards that at the time are commonly insured against in the case of projects similar in nature, construction type, and geographic location to the Project and/or as otherwise required by any lender or mortgagee. Tenant shall carry and maintain during the entire Lease Term, at Tenant’s sole cost and expense, increased amounts of insurance to the extent required.

10.7 Landlord’s Insurance. Landlord shall maintain its usual liability insurance as well as property insurance for the Building (excluding any Alterations and Tenant Improvements).

11. DAMAGE AND DESTRUCTION

11.1 Repair of Damage to Premises by Landlord. Tenant shall promptly notify Landlord of any damage to the Premises resulting from fire or any other casualty. If the Premises or any Common Areas serving or providing access to the Premises shall be damaged by fire or other casualty, Landlord shall promptly and diligently, subject to reasonable delays for insurance adjustment or other matters beyond Landlord’s reasonable control, and subject to all other terms of this Article 11, restore such Common Areas and the Premises to substantially the same condition as existed prior to the casualty, except for modifications required by zoning and building codes and other laws or by the holder of a mortgage on the Building or Project or any other modifications to the Common Areas deemed desirable by Landlord, which are consistent with the character of the Project, provided that access to the Premises shall not be materially impaired. Upon the occurrence of any damage to the Premises, upon notice (the “Landlord Repair Notice”) to Tenant from Landlord, Tenant shall assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under Tenant’s insurance required under Section 10.3.2(ii) of this Lease and Landlord’s obligation to restore any Alterations or Tenant Improvements shall be limited to the extent of such proceeds received by Landlord. To the extent permitted pursuant to Applicable Laws, Landlord shall not be liable for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant’s business resulting in any way from such damage or the repair thereof; provided however, that if such fire or other casualty shall have damaged the Premises or Common Areas necessary to Tenant’s occupancy, and the Premises are not occupied by Tenant as a result thereof, then during the time and to the extent the Premises are unfit for occupancy, the Rent shall be abated in proportion to the ratio that the amount of rentable square feet of the Premises which is unfit for occupancy for the Permitted Use bears to the total rentable square feet of the Premises.

11.2 Landlord’s Option to Repair. Notwithstanding the terms of Section 11.1 of this Lease, Landlord may elect not to rebuild and/or restore the Premises, Building and/or Project, and instead terminate this Lease, by notifying Tenant in writing of such termination within sixty (60) days after the date of discovery of the damage, such notice to include a termination date giving Tenant sixty (60) days to vacate the Premises, but Landlord may so elect only if the Building or Project shall be damaged by fire or other casualty or cause, whether or not the Premises are affected, and one or more of the following conditions is present: (i) in Landlord’s reasonable judgment, repairs cannot reasonably be completed within one hundred eighty (180) days after the date of discovery of the damage (when such repairs are made without the payment of overtime or other premiums); (ii) the holder of any mortgage on the Building or Project or ground lessor with respect to the Building or Project shall require that the insurance proceeds or any portion thereof be used to retire the mortgage debt, or shall terminate the ground lease, as the case may be; (iii) such damage is not fully covered by Landlord’s insurance policies; (iv) Landlord decides to rebuild the Building or Common Areas so that they will be substantially different structurally or architecturally; (v) the damage occurs during the last twelve (12) months of the Lease Term; or (vi) any owner of any other portion of the Project, other than Landlord, does not intend to repair the damage to such portion of the Project; provided, however, that if Landlord does not elect to terminate this Lease pursuant to Landlord’s termination right as provided above, and the repairs cannot, in the reasonable opinion of Landlord, be completed within one hundred eighty (180) days after being commenced, Tenant may elect, no earlier than sixty (60) days after the date of the damage and not later than ninety (90) days after the date of such damage, to terminate this Lease by written notice to Landlord effective as of the date specified in the notice, which date shall not be less than thirty (30) days nor more than sixty (60) days after the date such notice is given by Tenant. Notwithstanding the provisions of this Section 11.2, Tenant shall have the right to terminate this Lease under this Section 11.2 only if each of the following conditions is satisfied: (a) the damage to the Project by fire or other casualty was not caused by the negligence or intentional act of Tenant or any Tenant Party; (b) as a result of the damage, Tenant cannot reasonably conduct business from the Premises; and, (c) as a result of the damage to the Project, Tenant does not occupy or use the Premises at all. In addition, Tenant may terminate this Lease if the damage to the Premises occurs during the last twelve (12) months of the Lease Term, and, as a result of such damage, Tenant cannot reasonably conduct business from the Premises for a period of at least one-half (1/2) of the then-remaining term. In no event shall Landlord have any obligation to undertake restoration on account of any casualty except to the extent of the insurance proceeds actually received by Landlord.

-26-

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

12. NONWAIVER

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

13. CONDEMNATION

13.1 If the whole or substantially all of the Premises, Building or Project shall be taken by power of eminent domain or condemned by any competent authority for any public or quasi-public use or purpose, or if all reasonable access to the Building is so taken or condemned, or if Landlord shall grant a deed or other instrument in lieu of such taking by eminent domain or condemnation, Landlord shall have the option to terminate this Lease effective as of the date possession is required to be surrendered to the authority. Tenant shall not because of such taking assert any claim against Landlord or the authority for any compensation because of such taking and Landlord shall be entitled to the entire award or payment in connection therewith, except that Tenant shall have the right to file any separate claim available to Tenant for any taking of Tenant’s personal property and fixtures belonging to Tenant and removable by Tenant upon expiration of the Lease Term pursuant to the terms of this Lease, and for moving expenses, so long as such claims do not diminish the award available to Landlord, its ground lessor with respect to the Building or Project or its mortgagee, and such claim is payable separately to Tenant. All Rent shall be apportioned as of the date of such termination. If any part of the Premises shall be taken, and this Lease shall not be so terminated, the Rent shall be proportionately abated. Notwithstanding anything to the contrary contained in this Article 13, in the event of a temporary taking of all or any portion of the Premises for a period of one hundred and eighty (180) days or less, and provided that such temporary taking does not materially preclude or unreasonably diminish Tenant’s ability to conduct business from the Premises, then this Lease shall not terminate but the Base Rent and Tenant’s Share of Direct Expenses shall be abated for the period of such taking in proportion to the ratio that the amount of rentable square feet of the Premises taken bears to the total rentable square feet of the Premises. Tenant hereby waives any and all rights it might otherwise have pursuant to Section 1265.130 of The California Code of Civil Procedure. Landlord shall be entitled to receive the entire award made in connection with any such temporary taking, provided, however, that Tenant shall be entitled to a share of the award for any loss of fixtures and improvements and for moving and other reasonable expenses that do not otherwise reduce Landlord’s recovery. If this Lease does not terminate on account of any such eminent domain or condemnation proceeding, then Landlord shall, to the extent practicable, restore the affected area of the Premises, Building or Project. In no event shall Landlord have any obligation to undertake restoration on account of any condemnation or eminent domain proceeding except to the extent of the award actually received by Landlord.

-27-

14. ASSIGNMENT AND SUBLETTING

14.1 Transfers. Tenant shall not, without the prior written consent of Landlord, assign, mortgage, pledge, hypothecate, encumber, or permit any lien to attach to, or otherwise transfer, this Lease or any interest hereunder, permit any assignment, or other transfer of this Lease or any interest hereunder by operation of law, sublet the Premises or any part thereof, or enter into any license or concession agreements or otherwise permit the occupancy or use of the Premises or any part thereof by any persons other than Tenant and its employees and contractors (all of the foregoing are hereinafter sometimes referred to collectively as “Transfers” and any person to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a “Transferee”). If Tenant desires Landlord’s consent to any Transfer, Tenant shall notify Landlord in writing, which notice (the “Transfer Notice”) shall include (i) the proposed effective date of the Transfer, which shall not be less than twenty (20) days nor more than one hundred eighty (180) days after the date of delivery of the Transfer Notice, (ii) a description of the portion of the Premises to be transferred (the “Subject Space”), (iii) all of the terms of the proposed Transfer and the consideration therefor, including calculation of the “Transfer Premium”, as that term is defined in Section 14.3 below, in connection with such Transfer, the name and address of the proposed Transferee, and a copy of all existing executed and/or proposed documentation pertaining to the proposed Transfer, and (iv) current financial statements of the proposed Transferee certified by an officer, partner or owner thereof, business credit and personal references and history of the proposed Transferee and any other information reasonably required by Landlord which will enable Landlord to determine the financial responsibility, character, and reputation of the proposed Transferee, nature of such Transferee’s business and proposed use of the Subject Space. Any Transfer made without Landlord’s prior written consent shall, at Landlord’s option, be null, void and of no effect, and shall, at Landlord’s option, constitute a default by Tenant under this Lease. Whether or not Landlord consents to any proposed Transfer, Tenant shall pay Landlord’s reasonable review and processing fees, as well as any reasonable professional fees (including, without limitation, attorneys’, accountants’, architects’, engineers’ and consultants’ fees) incurred by Landlord, within thirty (30) days after written request by Landlord.

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

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

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

14.2.3 The Transferee is not a party of reasonable financial worth and/or financial stability in light of the responsibilities to be undertaken in connection with the Transfer on the date consent is requested;

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

14.2.5 Either the proposed Transferee, or any person or entity which directly or indirectly, controls, is controlled by, or is under common control with, the proposed Transferee, is negotiating with Landlord or has negotiated with Landlord during the six (6) month period immediately preceding the date Landlord receives the Transfer Notice, to lease space in the Project.

14.2.6 In Landlord’s reasonable determination, the sub-rent, additional rent or other amounts received or accrued by Tenant from subleasing, assigning or otherwise Transferring all or any portion of the Premises is based on the income or profits of any person, or the assignment or sublease could cause any portion of the amounts received by Landlord pursuant to this Lease to fail to qualify as “rents from real property” within the meaning of section 856(d) of the Internal Revenue Code of 1986, as amended (the “Code”), or any similar or successor provision thereto or which would cause any other income of Landlord to fail to qualify as income described in section 856(c)(2) of the Code.

-28-

If Landlord consents to any Transfer pursuant to the terms of this Section 14.2 (and does not exercise any recapture rights Landlord may have under Section 14.4 of this Lease), Tenant may within six (6) months after Landlord’s consent, but not later than the expiration of said six-month period, enter into such Transfer of the Premises or portion thereof, upon substantially the same terms and conditions as are set forth in the Transfer Notice furnished by Tenant to Landlord pursuant to Section 14.1 of this Lease, provided that if there are any changes in the terms and conditions from those specified in the Transfer Notice (i) such that Landlord would initially have been entitled to refuse its consent to such Transfer under this Section 14.2, Tenant shall again submit the Transfer to Landlord for its approval and other action under this Article 14 (including Landlord’s right of recapture, if any, under Section 14.4 of this Lease). Notwithstanding anything to the contrary in this Lease, if Tenant or any proposed Transferee claims that Landlord has withheld or delayed its consent in violation of this Section 14.2 or otherwise has breached its obligations under this Article 14, their sole remedies shall be a suit for contract damages (other than damages for injury to, or interference with, Tenant’s business including, without limitation, loss of profits, however occurring) or declaratory judgment and an injunction for the relief sought, and Tenant hereby waives 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.

14.3 Transfer Premium. If Landlord consents to a Transfer, as a condition thereto which the parties hereby agree is reasonable, Tenant shall pay to Landlord fifty percent (50%) of any “Transfer Premium”, as that term is defined in this Section 14.3, received by Tenant from such Transferee (other than any Permitted Transferee). “Transfer Premium” shall mean all rent, additional rent or other consideration payable by such Transferee in connection with the Transfer in excess of the Rent and Additional Rent payable by Tenant under this Lease during the term of the Transfer on a per rentable square foot basis if less than all of the Premises is transferred, after deducting the reasonable third party expenses incurred by Tenant for (i) any design and construction costs incurred on account of changes, alterations and improvements to the Premises in connection with the Transfer, (ii) any free base rent and tenant improvement allowances reasonably provided to the Transferee in connection with the Transfer (provided that such free rent and tenant improvement allowances shall be deducted only to the extent the same is included in the calculation of total consideration payable by such Transferee), (iii) any brokerage commissions in connection with the Transfer, and (iv) legal fees and disbursements reasonably incurred in connection with the Transfer (collectively, “Tenant’s Subleasing Costs”). “Transfer Premium” shall also include, but not be limited to, any lump sum payment, key money, bonus money or other cash consideration paid by Transferee to Tenant in connection with such Transfer, and any payment in excess of fair market value for services rendered by Tenant to Transferee or for assets, fixtures, inventory, equipment, or furniture transferred by Tenant to Transferee in connection with such Transfer. The determination of the amount of Landlord’s applicable share of the Transfer Premium shall be made on a monthly basis as rent or other consideration is received by Tenant under the Transfer.

14.4 Landlord’s Option as to Subject Space. Notwithstanding anything to the contrary contained in this Article 14, in the event Tenant contemplates a Transfer, Tenant shall give Landlord notice (the “Intention to Transfer Notice”) of such contemplated Transfer (whether or not the contemplated Transferee or the terms of such contemplated Transfer have been determined). The Intention to Transfer Notice shall specify the portion of and amount of rentable square feet of the Premises which Tenant intends to Transfer (the “Contemplated Transfer Space”), the contemplated date of commencement of the Contemplated Transfer (the “Contemplated Effective Date”), and the contemplated length of the term of such contemplated Transfer, and shall specify that such Intention to Transfer Notice is delivered to Landlord pursuant to this Section 14.4 in order to allow Landlord to elect to recapture the Contemplated Transfer Space. Thereafter, Landlord shall have the option, by giving written notice to Tenant (a “Recapture Notice”) within twenty (20) days after receipt of any Intention to Transfer Notice, to recapture the Contemplated Transfer Space. Such recapture shall cancel and terminate this Lease with respect to such Contemplated Transfer Space as of the Contemplated Effective Date. In the event of a recapture by Landlord, if this Lease shall be canceled with respect to less than the entire Premises, the Rent reserved herein shall be prorated on the basis of the number of rentable square feet retained by Tenant in proportion to the number of rentable square feet contained in the Premises, and this Lease as so amended shall continue thereafter in full force and effect, and upon request of either party, the parties shall execute written confirmation of the same. Landlord and Tenant shall share equally in the costs to demise any such portion of the Premises recaptured by Landlord pursuant to this Section 14.4.

-29-

14.5 Effect of Transfer. If Landlord consents to a Transfer, (i) the terms and conditions of this Lease shall in no way be deemed to have been waived or modified, (ii) such consent shall not be deemed consent to any further Transfer by either Tenant or a Transferee, (iii) Tenant shall deliver to Landlord, promptly after execution, an original executed copy of all documentation pertaining to the Transfer in form reasonably acceptable to Landlord, (iv) Tenant shall furnish upon Landlord’s request a complete statement, certified by an independent certified public accountant, or Tenant’s chief financial officer, setting forth in detail the computation of any Transfer Premium Tenant has derived and shall derive from such Transfer, and (v) no Transfer relating to this Lease or agreement entered into with respect thereto, whether with or without Landlord’s consent, shall relieve Tenant or any guarantor of the Lease from any liability under this Lease, including, without limitation, in connection with the Subject Space. Landlord or its authorized representatives shall have the right at all reasonable times to audit the books, records and papers of Tenant relating to any Transfer, and shall have the right to make copies thereof. If the Transfer Premium respecting any Transfer shall be found understated, Tenant shall, within thirty (30) days after demand, pay the deficiency, and if understated by more than two percent (2%), Tenant shall pay Landlord’s costs of such audit.

14.6 Sublease/Transfer Restrictions. Notwithstanding anything contained herein to the contrary and without limiting the generality of Section 14.1 above, Tenant shall not: (a) sublet all or part of the Premises or assign or otherwise Transfer this Lease on any basis such that the rental or other amounts to be paid by the subtenant or assignee thereunder would be based, in whole or in part, on the income or profits derived by the business activities of the subtenant or assignee; (b) sublet all or part of the Premises or assign this Lease to any person or entity in which, under Section 856(d)(2)(B) of the Code, Longfellow REIT, Inc., a Delaware corporation (the “Company”), or any affiliate of the Company owns, directly or indirectly (by applying constructive ownership rules set forth in Section 856(d) (5) of the Code), a ten percent (10%) or greater interest; or (c) sublet all or part of the Premises or assign this Lease in any other manner or otherwise derive any income which could cause any portion of the amounts received by Landlord pursuant hereto or any sublease to fail to qualify as “rents from real property” within the meaning of Section 856(d) of the Code, or which could cause any other income received by Landlord to fail to qualify as income described in Section 856(c) (2) of the Code. The requirements of this Section 14.4 shall likewise apply to any further subleasing, assignment or other Transfer by any subtenant or assignee. All references herein to Section 856 of the Code also shall refer to any amendments thereof or successor provisions thereto.

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

14.8 Non-Transfers. Notwithstanding anything to the contrary contained in this Article 14, a sale of corporate shares of capital stock in Tenant raise capital to grow and to expand Tenant’s business (e.g., a sale of shares in Tenant in connection with an initial public offering of Tenant’s stock, or any other transfer of Tenant’s stock, on a nationally-recognized stock exchange) (any of the foregoing, a “Permitted Transferee”), shall not be deemed a Transfer under this Article 14, provided that Tenant notifies Landlord of any such assignment or sublease and promptly supplies Landlord with any documents or information requested by Landlord regarding such Transfer. No such permitted assignment or subletting or other Transfer permitted with or without Landlord’s consent pursuant to this Article 14 shall serve to release Tenant from any of its obligations under this Lease.

15. SURRENDER OF PREMISES; OWNERSHIP AND REMOVAL OF TRADE FIXTURES

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

15.2 Removal of Tenant Property by Tenant. Upon the expiration of the Lease Term, or upon any earlier termination of this Lease, Tenant shall, subject to the provisions of this Article 15, quit and surrender possession of the Premises to Landlord in as good order and condition as when Tenant took possession and as thereafter improved by Landlord and/or Tenant, reasonable wear and tear and repairs which are specifically made the responsibility of Landlord hereunder excepted. Upon such expiration or termination, Tenant shall, without expense to Landlord, remove or cause to be removed from the Premises all Alterations that Tenant is required to remove in accordance with Section 8.3 of this Lease, any debris and rubbish, and such items of furniture, equipment, free-standing cabinet work, movable partitions and other articles of personal property owned by Tenant or installed or placed by Tenant at its expense in the Premises, and such similar articles of any other persons claiming under Tenant (unless Landlord, in its sole discretion, waives the requirement that any item of personal property be removed), and Tenant shall repair at its own expense all damage to the Premises and Building resulting from such removal. Tenant’s personal property includes only those items that are not built into the Premises and that have not been constructed or installed by Landlord.

15.3 Environmental Assessment. Prior to the expiration of the Lease (or within thirty (30) days after any earlier termination), Tenant shall clean and otherwise decommission all interior surfaces (including floors, walls, ceilings, and counters), piping, supply lines, waste lines and plumbing in or serving the Premises, and all exhaust or other ductwork in or serving the Premises, in each case that has carried, released or otherwise been exposed to any Hazardous Materials due to Tenant’s use or occupancy of the Premises, and shall otherwise clean the Premises so as to permit the Environmental Assessment called for by this Section 15.3 to be issued. Prior to the expiration of this Lease (or within thirty (30) days after any earlier termination), Tenant, at Tenant’s expense, shall obtain for Landlord a report (an “Environmental Assessment”) addressed to Landlord (and, at Tenant’s election, Tenant) by a reputable licensed environmental engineer or industrial hygienist that is designated by Tenant and acceptable to Landlord in Landlord’s reasonable discretion, which report shall be based on the environmental engineer’s inspection of the Premises and shall state, to Landlord’s reasonable satisfaction, that (a) the Hazardous Materials described in the first sentence of this paragraph, to the extent, if any, existing prior to such decommissioning, have been removed in accordance with Applicable Laws; (b) all Hazardous Materials described in the first sentence of this paragraph, if any, have been removed in accordance with Applicable Laws from the interior surfaces of the Premises (including floors, walls, ceilings, and counters), piping, supply lines, waste lines and plumbing, and all such exhaust or other ductwork in the Premises, may be reused by a subsequent tenant or disposed of in compliance with Applicable Laws without incurring special costs or undertaking special procedures for demolition, disposal, investigation, assessment, cleaning or removal of such Hazardous Materials and without giving notice in connection with such Hazardous Materials; and (c) the Premises may be reoccupied for office, research and development, or laboratory use, demolished or renovated without incurring special costs or undertaking special procedures for disposal, investigation, assessment, cleaning or removal of Hazardous Materials described in the first sentence of this paragraph and without giving notice in connection with Hazardous Materials. Further, for purposes of clauses (b) and (c), “special costs” or “special procedures” shall mean costs or procedures, as the case may be, that would not be incurred but for the nature of the Hazardous Materials as Hazardous Materials instead of non-hazardous materials. The report shall also include reasonable detail concerning the clean-up measures taken, the clean-up locations, the tests run and the analytic results. Tenant shall submit to Landlord the identity of the applicable consultants and the scope of the proposed Environmental Assessment for Landlord’s reasonable review and approval at least 30 days prior to commencing the work described therein or at least 60 days prior to the expiration of the Lease Term, whichever is earlier.

-31-

If Tenant fails to perform its obligations under this Section 15.3, without limiting any other right or remedy, Landlord may, on five (5) business days’ prior written notice to Tenant perform such obligations at Tenant’s expense if Tenant has not commenced to do so within said five day period, and Tenant shall within 10 days of written demand reimburse Landlord for all reasonable out-of-pocket costs and expenses incurred by Landlord in connection with such work. Tenant’s obligations under this Section 15.2 shall survive the expiration or earlier termination of this Lease. In addition, at Landlord’s election, Landlord may inspect the Premises and/or the Project for Hazardous Materials at Landlord’s cost and expense within sixty (60) days of Tenant’s surrender of the Premises at the expiration or earlier termination of this Lease. Tenant shall pay for all such costs and expenses incurred by Landlord in connection with such inspection if such inspection reveals that a release or threat of release of Hazardous Materials exists at the Project or Premises as a result of the acts or omission of Tenant, its officers, employees, contractors, and agents (except to the extent resulting from (i) Hazardous Materials existing in the Premises as at the delivery of possession to Tenant (in which event Landlord shall be responsible for any Clean-up, as provided in this Lease), or (ii) the acts or omissions of Landlord or Landlord’s agents, employees or contractors).

16. HOLDING OVER

If Tenant holds over after the expiration of the Lease Term or earlier termination thereof, with the express written consent of Landlord, such tenancy shall be from month-to-month only, and shall not constitute a renewal hereof or an extension for any further term. If Tenant holds over after the expiration of the Lease Term of earlier termination thereof, without the express written consent of Landlord, such tenancy shall be deemed to be a tenancy by sufferance only, and shall not constitute a renewal hereof or an extension for any further term. In either case, Base Rent shall be payable at a monthly rate equal to (x) one hundred fifty percent (150%) of the Base Rent applicable during the last rental period of the Lease Term for the first 60 days of such hold over, and (y) the higher of fair market rent and such one hundred fifty percent (150%) of the Base Rent applicable during the last rental period of the Lease Term for each day thereafter. Such month-to-month tenancy or tenancy by sufferance, as the case may be, shall be subject to every other applicable term, covenant and agreement contained herein, including without limitation the obligation to pay Additional Rent. Nothing contained in this Article 16 shall be construed as consent by Landlord to any holding over by Tenant, and Landlord expressly reserves the right to require Tenant to surrender possession of the Premises to Landlord as provided in this Lease upon the expiration or other termination of this Lease. The provisions of this Article 16 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. If Tenant fails to surrender the Premises upon the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from all loss, costs (including reasonable attorneys’ fees) and liability resulting from such failure, including, without limiting the generality of the foregoing, any claims made by any succeeding tenant founded upon such failure to surrender and/or any lost profits and consequential or indirect damages to Landlord resulting therefrom.

17. ESTOPPEL CERTIFICATES

Tenant shall execute, acknowledge and deliver to Landlord an estoppel certificate, which, as submitted by Landlord, shall be substantially in the form of Exhibit 17, attached hereto (or such other form as may be reasonably required by any prospective mortgagee or purchaser of the Project, or any portion thereof), indicating therein any exceptions thereto that may exist at that time, and shall also contain any other information reasonably requested by Landlord or Landlord’s mortgagee or prospective mortgagee. Any such certificate may be relied upon by any prospective mortgagee or purchaser of all or any portion of the Project. Tenant shall execute and deliver whatever other instruments may be reasonably required for such purposes. Failure of Tenant to timely execute, acknowledge and deliver such estoppel certificate or other instruments shall constitute an acceptance of the Premises and an acknowledgment by Tenant that statements included in the estoppel certificate are true and correct, without exception. At any time during the Lease Term, within ten (10) business days following a request in writing by Landlord, Landlord may require Tenant to provide Landlord with a current financial statement and financial statements of the two (2) years prior to the current financial statement year. Such statements shall be prepared in accordance with generally accepted accounting principles and, if such is the normal practice of Tenant, shall be audited by an independent certified public accountant. If no audited financial statement is prepared, such statement will be certified by the CFO or Treasurer of Tenant.

18. SUBORDINATION

This Lease shall be subject and subordinate to all future ground or underlying leases of the Building or Project and to the lien of any mortgage, trust deed or other encumbrances now or hereafter in force against the Building or Project or any part thereof, if any, and to all renewals, extensions, modifications, consolidations and replacements thereof, and to all advances made or hereafter to be made upon the security of such mortgages or trust deeds, unless the holders of such mortgages, trust deeds or other encumbrances, or the lessors under such ground lease or underlying leases require in writing that this Lease be superior thereto. Tenant covenants and agrees that in the event any proceedings are brought for the foreclosure of any such mortgage or deed in lieu thereof (or if any ground lease is terminated), to attorn, without any deductions or set-offs whatsoever, to the lienholder or purchaser or any successors thereto upon any such foreclosure sale or deed in lieu thereof (or to the ground lessor), if so requested to do so by such purchaser or lienholder or ground lessor. Notwithstanding any other provision of this Lease to the contrary, no holder of any such mortgage, trustee deed or other encumbrance and no such ground lessor, shall be obligated to perform or liable in damages for failure to perform any of Landlord’s obligations under this Lease unless and until such holder shall foreclose such mortgage, trust deed or other encumbrance, or the lessors under such ground lease or underlying leases otherwise acquire title to the Property, and then shall only be liable for Landlord’s obligations arising or accruing after such foreclosure or acquisition of title, provided the foregoing shall not release any such holder or ground lessor from performing ongoing obligations of Landlord from and after the date of such foreclosure or acquisition of title, such as repair and maintenance obligations. No such holder shall ever be obligated to perform or be liable in damages for any of Landlord’s obligations arising or accruing before such foreclosure or acquisition of title. Tenant shall, within ten (10) business days of request by Landlord, execute such further instruments or assurances as Landlord may reasonably deem necessary to evidence or confirm the subordination or superiority of this Lease to any such mortgages, trust deeds, ground leases or underlying leases. Tenant waives the provisions of any current or future statute, rule or law which may give or purport to give Tenant any right or election to terminate or otherwise adversely affect this Lease and the obligations of Tenant hereunder in the event of any foreclosure proceeding or sale.

Landlord’s interest herein may be assigned as security at any time to any Mortgagee. Notwithstanding the foregoing or anything to the contrary herein, no Mortgagee succeeding to the interest of Landlord hereunder shall be (i) liable in any way to Tenant for any act or omission, neglect or default on the part of Landlord under this Lease, (ii) responsible for any monies owing by or on deposit with Landlord to the credit of Tenant (except to the extent any such deposit is actually received by such mortgagee or ground lessor), (iii) subject to any counterclaim or setoff which theretofore accrued to Tenant against Landlord, (iv) bound by any amendment or modification of this Lease subsequent to such mortgage, or by any previous prepayment of Rent for more than one (1) month, which was not approved in writing by the Mortgagee, (v) liable beyond such Mortgagee’s interest in the Project, or (vi) responsible for the payment or performance of any work to be done by Landlord under this Lease to render the Premises ready for occupancy by Tenant or for the payment of any tenant improvements allowances. Nothing in clause (i), above, shall be deemed to relieve any Mortgagee succeeding to the interest of Landlord hereunder of its obligation to comply with the obligations of Landlord under this Lease from and after the date of such succession.

No Mortgagee shall, either by virtue of the Mortgage or any assignment of leases executed by Landlord for the benefit of such Mortgagee, be or become a mortgagee in possession or be or become subject to any liability or obligation under the Lease or otherwise until such Mortgagee shall have acquired the interest of Landlord in the Property, by foreclosure or otherwise, or in fact have taken possession of the Property as a mortgagee in possession and then such liability or obligation of Mortgagee under the Lease shall extend only to those liability or obligations accruing subsequent to the date that such Mortgagee has acquired the interest of Landlord in the Premises, or in fact taken possession of the Property as a mortgagee in possession.

19. DEFAULTS; REMEDIES

19.1 Events of Default. The occurrence of any of the following shall constitute a default of this Lease by Tenant:

19.1.1 Any failure by Tenant to pay any Rent or any other charge required to be paid under this Lease, or any part thereof, when due and such failure shall continue for five (5) days after notice of such failure is given to Tenant, except that if Landlord shall have given one (1) such notice in any twelve (12) month period, Tenant shall not be entitled to any further notice of its delinquency in the payment of Rent or any other charge required to be paid under this Lease until such time as twelve (12) consecutive months shall have elapsed without Tenant having defaulted in any such payment; or

-33-

19.1.2 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 by Tenant under this Section 19.1.2, any failure by Tenant to observe or perform any other provision, covenant or condition of this Lease to be observed or performed by Tenant where such failure continues for thirty (30) days after written notice thereof from Landlord to Tenant; provided that if the nature of such default is such that the same cannot reasonably be cured within a thirty (30) day period, Tenant shall not be deemed to be in default if it diligently commences such cure within such period and thereafter diligently proceeds to rectify and cure such default; or

19.1.3 Abandonment of the Premises by Tenant; or

19.1.4 The failure by Tenant to observe or perform according to the provisions of Articles 5, 14, 17 or 18 of this Lease where such failure continues for more than two (2) business days after notice from Landlord;

19.1.5 If a receiver, guardian, conservator, trustee in bankruptcy or similar officer shall be appointed by a court of competent jurisdiction to take charge of all or any part of Tenant’s or any guarantor’s property and such appointment is not discharged within 90 days thereafter or if a petition including, without limitation, a petition for reorganization or arrangement is filed by Tenant or any guarantor under any bankruptcy law or is filed against Tenant or any guarantor and, in the case of a filing against Tenant only, the same shall not be dismissed within 90 days from the date upon which it is filed.

The notice periods provided herein are in lieu of, and not in addition to, any notice periods provided by law.

19.2 Remedies Upon Default. Upon the occurrence of any event of default by Tenant beyond applicable notice and cure periods, Landlord shall have, in addition to any other remedies available to Landlord at law or in equity (all of which remedies shall be distinct, separate and cumulative), the option to pursue any one or more of the following remedies, each and all of which shall be cumulative and nonexclusive, without any notice or demand whatsoever. Tenant hereby waives, for Tenant and for all those claiming under Tenant, any and all rights now or hereafter existing to redeem by order or judgment of any court or by any legal process or writ, Tenant’s right of occupancy of the Premises after any termination of this Lease.

19.2.1 Terminate this Lease (pursuant to Section 1951.2 of the California Civil Code), in which event Tenant shall immediately surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and take possession of the Premises and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without being liable for prosecution or any claim or damages therefor; and Landlord may recover from Tenant the following:

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

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

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

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

-34-

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

The term “rent” as used in this Section 19.2 shall be deemed to be and to mean all sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or to others. As used in Sections 19.2.1(i) and (ii), above, the “worth at the time of award” shall be computed by allowing interest at the rate set forth in Article 25 of this Lease, but in no case greater than the maximum amount of such interest permitted by law. As used in Section 19.2.1(iii) above, the “worth at the time of award” shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one percent (1%).

19.2.2 Landlord shall have the remedy described in California Civil Code Section 1951.4 (lessor may continue lease in effect after lessee’s breach and abandonment and recover rent as it becomes due, if lessee has the right to sublet or assign, subject only to reasonable limitations). Accordingly, if Landlord does not elect to terminate this Lease on account of any default by Tenant, Landlord may, from time to time, without terminating this Lease, enforce all of its rights and remedies under this Lease, including the right to recover all rent as it becomes due.

19.2.3 Landlord shall at all times have the rights and remedies (which shall be cumulative with each other and cumulative and in addition to those rights and remedies available under this Section 19.2, or any law or other provision of this Lease), without prior demand or notice except as required by Applicable Law, to seek any declaratory, injunctive or other equitable relief, and specifically enforce this Lease, or restrain or enjoin a violation or breach of any provision hereof. The provisions of this Section 19.2.6 are not dependent upon the occurrence of a default.

19.2.4 Any obligation imposed by law upon Landlord to relet the Premises after any termination of the Lease shall be subject to the reasonable requirements of Landlord to lease to high quality tenants on such terms as Landlord may from time to time deem appropriate and to develop the Building in a harmonious manner with an appropriate mix of uses, tenants, floor areas and terms of tenancies, and the like, and Landlord shall not be obligated to relet the Premises to any party to whom Landlord or its affiliate may desire to lease other available space in the Building.

19.2.5 Nothing herein shall limit or prejudice the right of Landlord to prove and obtain in a proceeding for bankruptcy, insolvency, arrangement or reorganization, by reason of the termination, an amount equal to the maximum allowed by a statute of law in effect at the time when, and governing the proceedings in which, the damages are to be proved, whether or not the amount is greater to, equal to, or less than the amount of the loss or damage which Landlord has suffered.

19.3 Subleases of Tenant. Whether or not Landlord elects to terminate this Lease on account of any default by Tenant, as set forth in this Article 19, Landlord shall have the right to terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises or may, in Landlord’s sole discretion, succeed to Tenant’s interest in such subleases, licenses, concessions or arrangements. In the event of Landlord’s election to succeed to Tenant’s interest in any such subleases, licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder.

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

19.5 Landlord Default.

19.5.1 General. Notwithstanding anything to the contrary set forth in this Lease, Landlord shall not be in default in the performance of any obligation required to be performed by Landlord pursuant to this Lease unless Landlord fails to perform such obligation within thirty (30) days after the receipt of notice from Tenant specifying in detail Landlord’s failure to perform; provided, however, if the nature of Landlord’s obligation is such that more than thirty (30) days are required for its performance, then Landlord shall not be in default under this Lease if it shall commence such performance within such thirty (30) day period and thereafter diligently pursue the same to completion.

-35-

20. COVENANT OF QUIET ENJOYMENT

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

21. SECURITY DEPOSIT

21.1 Concurrently with Tenant’s execution of this Lease, Tenant shall deposit with Landlord a letter of credit (the “L/C Security”) in the amount set forth in Section 9 of the Summary (but Tenant shall increase the amount of the L/C Security to Five Hundred Thousand Dollars ($500,000) before it commences constructing the Tenant Improvements contemplated by the Work Letter attached hereto as Exhibit 1.1.1-2) as security for the faithful performance by Tenant of all of its obligations under this Lease as follows:

(a) Tenant shall provide Landlord, and maintain in full force and effect throughout the Term and until the date that is ninety (90) days after the Lease Expiration Date, an evergreen letter of credit substantially in the form of Exhibit 21.1 issued by an issuer reasonably satisfactory to Landlord, in the amount set forth in Section 9 of the Summary. If at any time during the Term (i) Landlord determines in its sole reasonable discretion that the financial condition of such issuer has changed in any materially adverse way from the financial condition of such issuer as of the date of execution of this Lease including, without limitation, if such issuer is declared insolvent or is placed into receivership or conservatorship by the Federal Deposit Insurance Corporation, or any successor or similar entity, if a trustee, receiver or liquidator is appointed for such issuer, if the credit rating of the long-term debt of the issuer of the letter of credit (according to Moody’s, Standard & Poor’s or similar national rating agency reasonably identified by Landlord) is downgraded to a grade below investment grade, if the issuer enters into any supervisory agreement with any governmental authority or fails to meet any capital requirements imposed by applicable law, Landlord may require the L/C Security to be replaced by an L/C Security issued by a different issuer, in which event Tenant shall within five (5) days after written notice from Landlord deliver to Landlord a replacement L/C Security issued by a commercial bank or savings and loan association acceptable to Landlord in its sole reasonable discretion and that meets all other requirements of this Article. If Tenant has actual notice, or Landlord notifies Tenant at any time, that any issuer of the L/C Security has become insolvent or placed into FDIC receivership, then Tenant shall promptly deliver to Landlord (without the requirement of further notice from Landlord) substitute L/C Security issued by a commercial bank or savings and loan association acceptable to Landlord in its sole discretion and that meets all other requirements of this Article. As used herein with respect to the issuer of the L/C Security, “insolvent” shall mean the determination of insolvency as made by such issuer’s primary bank regulator (i.e., the state bank supervisor for state chartered banks; the OCC or OTS, respectively, for federally chartered banks or thrifts; or the Federal Reserve for its member banks).

(b) Landlord may draw upon the L/C Security, and hold and apply the proceeds for the payment of any Rent or any other sum in default, or to compensate Landlord for any other loss or damage that Landlord may suffer by reason of Tenant’s default, if: (i) a default beyond applicable notice and cure periods exists (or would have existed with the giving of notice and passage of applicable cure periods, but only if transmittal of a default notice is stayed or barred by applicable bankruptcy or other similar law); (ii) as of the date forty-five (45) days before any L/C Security expires Tenant has not delivered to Landlord an amendment or replacement for such L/C Security, reasonably satisfactory to Landlord, extending the expiry date to the date that is ninety (90) days after the then-current Lease Expiration Date; (iii) Tenant fails to pay any bank charges for Landlord’s transfer of the L/C Security when due; or (iv) the issuer of the L/C Security ceases, or announces that it will cease, to maintain an office in the city where Landlord may present drafts under the L/C Security (and fails to permit drawing upon the L/C Security by overnight courier or facsimile). This Section does not limit any other provisions of this Lease allowing Landlord to draw the L/C Security under specified circumstances. In the event of any such draw upon the L/C Security, Tenant shall within 10 business days thereafter provide Landlord with a replacement letter of credit, or amendment to the existing letter of credit increasing the amount of such letter of credit, in the amount of L/C Security, and in the form, required hereunder, and Tenant’s failure to do so shall be a material breach of this Lease. Landlord shall hold the proceeds of any draw not applied as set forth above as a cash Security Deposit as further described below.

-36-

(c) If Landlord transfers its interest in the Premises, then Landlord shall transfer the L/C Security to the transferee of its interest and notify Tenant of such transfer, and Tenant shall at Tenant’s expense, within fifteen (15) business days after receiving a request from Landlord, deliver (and, if the issuer requires, Landlord shall consent to) an amendment to the L/C Security naming Landlord’s grantee as substitute beneficiary. If the required Security Deposit changes while L/C Security is in force, then Tenant shall deliver (and, if the issuer requires, Landlord shall consent to) a corresponding amendment to the L/C Security.

(d) Notwithstanding anything to the contrary contained in this Section 21, the required amount of the L/C Security will decline as follows:

(i) If (1) more than thirty-six (36) months of the Lease Term have elapsed and Tenant is not in default under the terms of this Lease beyond any applicable notice and cure period, and (2) Tenant provides to Landlord satisfactory evidence that Tenant has increased its financial liquidity (in comparison to its financial liquidity as of the date of this Lease) by at least Fifteen Million Dollars ($15,000,000) solely by virtue of any of the following means (alone or in combination): the closing of a public offering, private placement or other equity financing, the receipt of royalty payments, licensing payments or other milestone payments pursuant to any license agreement or other revenue agreement, or the receipt of grant funding, Tenant may thereafter reduce the amount of the L/C Security to Two Hundred Thousand Dollars ($200,000). In order to establish a benchmark for Tenant’s financial liquidity as of the date of this Lease, Landlord and Tenant acknowledge and agree that Tenant’s financial liquidity shall be deemed to be Six Million Three Hundred Thousand Dollars ($6,300,000).

(ii) If Tenant is not in default under the terms of this Lease beyond any applicable notice and cure period during the initial forth-eight (48) months of the Lease Term, Tenant may thereafter reduce the amount of the L/C Security by the amount of One Hundred Thousand Dollars ($100,000) for the balance of the Lease Term; provided, however, if Tenant already reduced the amount of the L/C Security pursuant to Section 21(d)(i) above, then Tenant shall not be eligible for any additional or further reduction in the amount of the L/C Security pursuant to this Section 21(d)(ii).

(iii) If Tenant is not in default under the terms of this Lease beyond any applicable notice and cure period during the initial seventy-two (72) months of the Lease Term, Tenant may thereafter reduce the amount of the L/C Security by the amount of One Hundred Thousand Dollars ($100,000) for the balance of the Lease Term; provided, however, if Tenant already reduced the amount of the L/C Security pursuant to Section 21(d)(i) above, then Tenant shall not be eligible for any additional or further reduction in the amount of the L/C Security pursuant to this Section 21(d)(iii).

(iv) For the sake of clarity, the maximum reduction in the amount of the L/C Security shall be Three Hundred Thousand Dollars ($300,000) [i.e., under no circumstances will the required amount of the L/C Security ever be less than Two Hundred Thousand Dollars ($200,000)].

-37-

(e) If and to the extent Landlord is holding the proceeds of the L/C Security in cash from time to time, such cash shall be held by Landlord as security for the faithful performance by Tenant of all of the terms, covenants and conditions of this Lease to be kept and performed by Tenant during the period commencing on the Execution Date and ending upon the expiration or termination of Tenant’s obligations under this Lease. If Tenant defaults (beyond applicable notice and cure periods) with respect to any provision of this Lease, including any provision relating to the payment of Rent, then Landlord may (but shall not be required to) use, apply or retain all or any part of the Security Deposit for the payment of any Rent or any other sum in default, or to compensate Landlord for any other loss or damage that Landlord may suffer by reason of Tenant’s default as provided in this Lease. The provisions of this Article shall survive the expiration or earlier termination of this Lease. In the event of bankruptcy or other debtor-creditor proceedings against Tenant, any cash security then being held by Landlord shall be deemed to be applied first to the payment of Rent and other charges due Landlord for all periods prior to the filing of such proceedings. Landlord shall deliver or credit to any purchaser of Landlord’s interest in the Premises the funds then held hereunder by Landlord, and thereupon (and upon confirmation by the transferee of such funds, whether expressly or by written assumption of this Lease, generally) Landlord shall be discharged from any further liability with respect to such funds. This provision shall also apply to any subsequent transfers. If Tenant shall fully and faithfully perform every provision of this Lease to be performed by it, then the cash security, if any, or any balance thereof, shall be returned to Tenant (or, at Landlord’s option, to the last assignee of Tenant’s interest hereunder) within 90 days after the expiration or earlier termination of this Lease. If and to the extent the security held by Landlord hereunder shall be in cash, Landlord shall hold such cash in an account at a banking organization selected by Landlord; provided, however, that Landlord shall not be required to maintain a separate account for the cash security, but may intermingle it with other funds of Landlord. Landlord shall be entitled to all interest and/or dividends, if any, accruing on such cash security.

(f) Landlord acknowledges that it is presently in possession of a cash security deposit in the amount of Fifty Thousand Dollars ($50,000) pursuant to a certain lease dated October 6, 2008 with Tenant (as amended, the “Existing Lease”). Promptly after the expiration of the Existing Lease and Tenant’s return to Landlord of possession of the leased premises thereunder, Landlord shall return to Tenant such cash security deposit to the extent required in accordance with the terms of the Existing Lease.

22. INTENTIONALLY OMITTED

23. SIGNS

23.1 Signage. Tenant shall not install any signage (including, without limitation, any signs identifying Tenant’s name or advertising Tenant’s merchandise or otherwise) in or about the Premises that is visible from the exterior of the Premises or in any other part of the Project except as expressly permitted in this Section 23.1; provided, however, Tenant’s signage existing as of the date of this Lease shall be permitted so long as it is, and continues to be, in compliance with all Applicable Laws. Landlord shall provide Tenant with a building-standard multi-tenant lobby directory listing and a multi-tenant floor directory listing identifying Tenant. Such signage shall be comparable to that used by Landlord for other similar floors in the Building and shall comply with Landlord’s then-current Building standard signage program. Subject to Landlord’s prior written approval, in its reasonable discretion, and provided all signs are in keeping with the quality, design and style of the Building and Project, Tenant, at its sole cost and expense, may install one sign identifying Tenant at the entry to the Premises on each floor of the Premises, which identification signage shall be consistent with building standard signage as determined by Landlord. All permitted signs shall be maintained by Tenant at its expense in a first-class and safe condition and appearance. Upon the expiration or earlier termination of this Lease, Tenant shall remove all of its signs at Tenant’s sole cost and expense. Tenant shall repair any damage to the Premises or Project, inside or outside, resulting from the erection, maintenance or removal of any signs. Tenant’s signage must also comply with all Applicable Laws. All Building signage shall be subject to the existing rights of other tenants in the Building and any declaration of covenants for the Project.

23.2 Prohibited Signage and Other Items. Any signs, notices, logos, pictures, names or advertisements which are installed and that have not been separately approved by Landlord may be removed without notice by Landlord at the sole expense of Tenant. Except as expressly permitted pursuant to Section 23.1, above, Tenant may not install any signs on the exterior or roof of the Project or the Common Areas. Any signs, displays, window coverings, window lettering, or blinds (even if the same are located behind the Landlord-approved window coverings for the Building), or other items or Alterations visible from the exterior of the Premises or Building, shall be subject to the prior approval of Landlord, in its sole reasonable discretion. Tenant shall not place or install any projections, antennae, aerials, or similar devices inside or outside of the Building, without the prior written approval of Landlord, subject to Tenant’s rights pursuant to Section 23.2, above.

-38-

24. COMPLIANCE WITH LAW

Tenant shall not do anything or suffer anything to be done by any Tenant Party in or about the Premises or the Project which will in any way conflict with any law, statute, ordinance or other federal, state or local governmental rule, regulation or requirement now in force or which may hereafter be enacted or promulgated (collectively, “Applicable Laws”). At its sole cost and expense, Tenant shall promptly comply with all such Applicable Laws which relate to (i) Tenant’s use of the Premises, (ii) any Alterations or Tenant Improvements, or (iii) the Building, but as to the Building, only to the extent such obligations are triggered by Alterations or Tenant Improvements, or Tenant’s particular use of the Premises and Project as opposed to office and laboratory use, generally. Tenant shall be responsible, at its sole cost and expense, to make all alterations to the Premises as are required to comply with the Applicable Laws to the extent required in this Article 22. Notwithstanding the foregoing terms of this Article 22 to the contrary, Tenant may defer such compliance with Applicable Laws while Tenant contests, in a court of proper jurisdiction, in good faith, the applicability of such Applicable Laws to the Premises or Tenant’s specific use or occupancy of the Premises; provided, however, Tenant may only defer such compliance if such deferral shall not (a) prohibit Tenant from obtaining or maintaining a certificate of occupancy for the Premises, (b) prohibit Landlord from obtaining or maintaining a certificate of occupancy for the Building or any portion thereof, (c) unreasonably and materially affect the safety of the employees and/or invitees of Landlord or of any tenant in the Building (including Tenant), (d) create a significant health hazard for the employees and/or invitees of Landlord or of any tenant in the Building (including Tenant), (e) otherwise materially and adversely affect Tenant’s use of or access to the Buildings or the Premises, or (f) impose material obligations, liability, fines, or penalties upon Landlord or any other tenant of the Building, or would materially and adversely affect the use of or access to the Building by Landlord or other tenants or invitees of the Building. The judgment of any court of competent jurisdiction or the admission of Tenant in any judicial action, regardless of whether Landlord is a party thereto, that Tenant has violated any of said governmental measures, shall be conclusive of that fact as between Landlord and Tenant. Landlord shall comply with all Applicable Laws relating to the Common Areas of the Building, provided that compliance with such Applicable Laws is not the responsibility of Tenant under this Lease, and provided further that Landlord’s failure to comply therewith would prohibit Tenant from obtaining or maintaining a certificate of occupancy for the Premises, or would unreasonably and materially affect the safety of Tenant’s employees or create a significant health hazard for Tenant’s employees, or would otherwise materially and adversely affect Tenant’s use of or access to the Premises. Landlord shall be permitted to include in Operating Expenses any costs or expenses incurred by Landlord under this Article 24 to the extent not prohibited by the terms of Section 4.2.7, above.

For purposes of Section 1938 of the California Civil Code, Landlord hereby discloses to Tenant, and Tenant hereby acknowledges, that neither the Premises, the Building nor the Common Areas have undergone inspection by a Certified Access Specialist (CASp). Pursuant to California Civil Code Section 1938, Tenant is hereby notified that a CASp can inspect the Premises and determine whether the Premises complies with all of the applicable construction-related accessibility standards under state law. Although state law does not require a CASp inspection of the Premises, Landlord may not prohibit Tenant from obtaining a CASp inspection of the Premises for the occupancy of the Tenant, if requested by Tenant. Landlord and Tenant shall mutually agree on the arrangements for the time and manner of any 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. If Tenant requests to perform a CASp inspection of the Premises, Tenant shall, at its cost, retain a CASp approved by Landlord (provided that Landlord may designate the CASp, at Landlord’s option) to perform the inspection of the Premises at a time agreed upon by the parties. Tenant shall provide Landlord with a copy of any report or certificate issued by the CASp (the “CASp Report”). Landlord and Tenant agree that any modifications necessary to correct violations of construction related accessibility standards identified in the CASp Report shall be the responsibility of Landlord. Tenant agrees to keep the information in the CASp Report confidential except as necessary for the Tenant to complete such modifications.

25. LATE CHARGES

If any installment of Rent or any other sum due from Tenant shall not be received by Landlord or Landlord’s designee within five (5) business days after the date due, then Tenant shall pay to Landlord a late charge equal to five percent (5%) of the overdue amount plus any reasonable attorneys’ fees incurred by Landlord by reason of Tenant’s failure to pay Rent and/or other charges when due hereunder. Notwithstanding the foregoing, Landlord shall not charge Tenant a late charge for the first (1^st) late payment in any twelve (12) month period unless Tenant fails to timely

-39-

pay such amount within five (5) business days following notice from Landlord that such amount is past due. The late charge shall be deemed Additional Rent and the right to require it shall be in addition to all of Landlord’s other rights and remedies hereunder or at law and shall not be construed as liquidated damages or as limiting Landlord’s remedies in any manner. In addition to the late charge described above, any Rent or other amounts owing hereunder which are not paid when due shall bear interest from the date when due until paid at a rate per annum equal to the lesser of (i) the annual “Bank Prime Loan” rate cited in the Federal Reserve Statistical Release Publication H.15, published on the first Tuesday of each calendar month (or such other comparable index as Landlord and Tenant shall reasonably agree upon if such rate ceases to be published) plus nine (9) percentage points, and (ii) the highest rate permitted by Applicable Law.

26. LANDLORD’S RIGHT TO CURE DEFAULT; PAYMENTS BY TENANT

26.1 Landlord’s Cure. All covenants and agreements to be kept or performed by Tenant under this Lease shall be performed by Tenant at Tenant’s sole cost and expense and without any reduction of Rent, except to the extent, if any, otherwise expressly provided herein. If Tenant shall fail to perform any obligation under this Lease, and such failure shall continue in excess of the time allowed under Section 19.1.2, above, unless a specific time period is otherwise stated in this Lease, Landlord may, but shall not be obligated to, make any such payment or perform any such act on Tenant’s part without waiving its rights based upon any default of Tenant and without releasing Tenant from any obligations hereunder. Except as may be specifically provided to the contrary in this Lease, Tenant shall pay to Landlord, upon delivery by Landlord to Tenant of statements therefor: (i) sums equal to expenditures reasonably made and obligations incurred by Landlord in connection with the remedying by Landlord of Tenant’s defaults pursuant to the provisions of Section 26.1; (ii) sums equal to all losses, costs, liabilities, damages and expenses referred to in Article 10 of this Lease; and (iii) sums equal to all expenditures made and obligations incurred by Landlord in collecting or attempting to collect the Rent or in enforcing or attempting to enforce any rights of Landlord under this Lease or pursuant to law, including, without limitation, all reasonable legal fees and other amounts so expended. Tenant’s obligations under this Section 26.1 shall survive the expiration or sooner termination of the Lease Term.

27. PROJECT CONTROL BY LANDLORD; ENTRY BY LANDLORD

27.1 Project Control. Landlord reserves full control over the Building and the Project to the extent not inconsistent with Tenant’s enjoyment of the Premises as provided by this Lease. This reservation includes Landlord’s right to subdivide the Project; convert the Building to condominium units; change the size of the Project by selling all or a portion of the Project or adding real property and any improvements thereon to the Project; grant assessments and licenses to third parties; maintain or establish ownership of the Building separate from fee title to the Property; make additions to or reconstruct portions of the Building and the Project; install, use, maintain, repair, replace and relocate for service to the Premises and other parts of the Building or the Project pipes, ducts, conduits, wires and appurtenant fixtures, wherever located in the Premises, the Building or elsewhere at the Project; and alter or relocate any other Common Area or facility, including private drives, lobbies and entrances. Landlord’s right pursuant to this Section 27.1, including without limitation the rights to construct, maintain, relocate, alter, improve, or adjust the Building or the Project shall be subject to the condition that (i) the exercise of any of such rights shall not materially and adversely interfere with Tenant’s use of the Premises or materially decrease the number of Tenant’s parking spaces, (ii) Landlord shall provide reasonable prior notice to Tenant before exercising any such rights which may materially and adversely interfere with Tenant’s use of the Premises, provided that such use of the Premises is in accordance with the Permitted Use, and (iii) Landlord shall use reasonable efforts to minimize to the extent possible any interference with Tenant’s business, provided that such business is in accordance with the Permitted Use, including, when reasonable, scheduling such work after business hours or on weekends. Possession of areas of the Premises necessary for utilities, services, safety and operation of the Building is reserved to Landlord. Notwithstanding the foregoing, Landlord shall provide Tenant reasonable prior notice of required access to the Premises for such activities.

27.2 Entry by Landlord. Landlord reserves the right at all reasonable times and upon not less than one (1) day’s prior notice to Tenant which may be given by telephone or electronic mail (except in the case of an emergency or with respect to regularly scheduled services) to enter the Premises to (i) inspect them; (ii) show the Premises to prospective purchasers, or to current or prospective mortgagees, ground or underlying lessors or insurers or, during the last twelve (12) months of the Lease Term, to prospective tenants; (iii) post notices of nonresponsibility (to the extent applicable pursuant to then Applicable Law); or (iv) alter, improve or repair the Premises or the Building, or for structural alterations, repairs or improvements to the Building or the Building’s systems and equipment and installing additional shafts, risers and raceways for the tenants or occupants of the floor beneath the applicable floor

-40-

of the Premises, provided Landlord will coordinate with Tenant the locating of any such shaft, riser or raceway so as to minimize any inconvenience or impact to Tenant’s use of the area designated for such shaft, riser or raceway. Provided that Landlord employs commercially reasonable efforts to minimize interference with the conduct of Tenant’s business in connection with entries into the Premises, Landlord may make any such entries without creating a default by Landlord and shall take such reasonable steps as required to accomplish the stated purposes. In an emergency, Landlord shall have the right to use any means that Landlord may deem proper to open the doors in and to the Premises. Landlord also shall have the right at any time, without the same constituting an actual or constructive eviction and without incurring any liability to Tenant therefor, to change the arrangement or location of entrances or passageways, doors and doorways, and corridors, elevators, stairs, toilet, or other public parts of the Building (not including the Premises) and to change the name, address, number or designation by which the Premises is commonly known, provided any such change does not (A) unreasonably reduce, interfere with or deprive Tenant of access to the Premises, or (B) reduce the rentable area (except by a de minimis amount) of the Premises. Any entry into the Premises by Landlord in the manner hereinbefore described shall not be deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an actual or constructive eviction of Tenant from any portion of the Premises and the Base Rent (and any other item of Rent) shall under no circumstances abate while said repairs, alterations, improvements, additions or restorations are being made, by reason of loss or interruption of business of Tenant, or otherwise. If Tenant shall not be present when for any reason entry into the Premises shall be necessary or permissible, Landlord or Landlord’s agents, representatives, contractors or employees may enter the same without rendering Landlord or such agents liable therefor if during such entry Landlord or Landlord’s agents shall accord reasonable care under the circumstances to Tenant’s Property, and without in any manner affecting this Lease. Tenant shall, at all times during the Term, be responsible for ensuring that Landlord has any and all keys, cards, codes or other means necessary to access the Premises.

28. TENANT PARKING

During the Term, Landlord shall provide Tenant with parking passes for use by standard size automobiles and small utility vehicles in an amount equal to the number of parking passes set forth in Section 10 of the Summary, which parking passes shall pertain to the on-site and/or off-site, as the case may be, parking facility (or facilities) which serve the Project. All such parking shall be on a first-come, first-serve basis in common with others entitled to use the same. Tenant’s continued right to use the parking passes is conditioned upon Tenant abiding by all rules and regulations which are prescribed from time to time for the orderly operation and use of the parking facility where the parking passes provide access (including any sticker or other identification system established by Landlord and the prohibition of vehicle repair and maintenance activities in the parking facilities), and Tenant shall cooperate in seeing that any Tenant Parties and Tenant visitors also comply with such rules and regulations. Tenant’s use of the parking passes for parking at the Project shall be at Tenant’s sole risk and Tenant acknowledges and agrees that Landlord shall have no liability whatsoever for damage to the vehicles of Tenant, its employees and/or visitors, or for other personal injury or property damage or theft relating to or connected with the parking rights granted herein or any of Tenant’s, its employees’ and/or visitors’ use of the parking facilities. Landlord shall have the right to assign its obligations under this Section 28 to an affiliate of Landlord or a third-party parking manager or operator, in which case Tenant shall make any payments due under this Section 28 directly to such other entity.

29. MISCELLANEOUS PROVISIONS

-41-

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

29.5 Transfer of Landlord’s Interest.

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

Neither Landlord, nor any of the Landlord Parties shall have any personal liability therefor beyond said amount, and Tenant hereby expressly waives and releases such personal liability on behalf of itself and all persons claiming by, through or under Tenant. The limitations of liability contained in this Section 29.13 shall inure to the benefit of Landlord’s and the Landlord Parties’ present and future partners, beneficiaries, officers, directors, trustees, shareholders, agents and employees, and their respective partners, heirs, successors and assigns. Under no circumstances shall any present or future partner of Landlord (if Landlord is a partnership), or trustee or beneficiary (if Landlord or any partner of Landlord is a trust), have any liability for the performance of Landlord’s obligations under this Lease. Notwithstanding any contrary provision herein, neither Landlord nor the Landlord Parties shall be liable under any circumstances for consequential or indirect damages, including without limitation injury or damage to, or interference with, Tenant’s business, loss of profits, loss of rents or other revenues, loss of business opportunity, loss of goodwill or loss of use, in each case, however occurring.

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

29.17 Force Majeure. Any prevention, delay or stoppage due to strikes, lockouts, labor disputes, acts of God, acts of war, terrorist acts, governmental action or inaction, inability to obtain services, labor, or materials or reasonable substitutes therefor, governmental actions, civil commotions, fire or other casualty, and other causes beyond the reasonable control of the party obligated to perform, except with respect to the obligations imposed with regard to Rent and other charges to be paid by Tenant pursuant to this Lease (collectively, a “Force Majeure”), notwithstanding anything to the contrary contained in this Lease, shall excuse the performance of such party for a period equal to any such prevention, delay or stoppage and, therefore, if this Lease specifies a time period for performance of an obligation of either party, that time period shall be extended by the period of any delay in such party’s performance caused by a Force Majeure.

29.26 Counterparts. This Lease may be executed in counterparts with the same effect as if both parties hereto had executed the same document. Both counterparts shall be construed together and shall constitute a single lease. Delivery by fax or by electronic mail file attachment of any executed counterpart to this Lease will be deemed the equivalent of the delivery of the original executed instrument.

29.27 Confidentiality.

-44-

29.28.2 Construction of Property and Other Improvements. Landlord and Tenant acknowledge that the Tenant Improvements (as defined in the Tenant Work Letter attached hereto as Exhibit 1.1.1-2) are contemplated by this Lease to be constructed by Tenant while Tenant is occupying the Temporary Premises. Tenant acknowledges that portions of the Project may be under construction during Tenant’s occupancy of the Premises, and that such construction may result in levels of noise, dust, obstruction of access, etc. which are in excess of that present in a fully constructed project. However, Tenant hereby acknowledges that Landlord is may during the Lease Term renovate, improve, alter or modify (collectively, the “Renovations”) the Project, the Building and/or the Premises. Landlord shall use commercially reasonable efforts to complete any Renovations in a manner which does not materially, adversely affect Tenant’s use of or access to the Premises, and if any Renovations adversely affect Tenant’s use of or access to the Premises at any time during the Lease Term, Landlord shall work with Tenant to implement commercially reasonable measures intended to mitigate the extent to which the Renovations materially, adversely affect Tenant’s use of or access to the Premises. Notwithstanding the foregoing, Tenant hereby agrees that such Renovations shall in no way constitute a constructive eviction of Tenant, and provided Landlord complies with its obligation to use commercially reasonable efforts to complete Renovations in a manner which does not materially, adversely affect Tenant’s use of or access to the Premises, such Renovations shall not entitle Tenant to any abatement of Rent. Landlord shall have no responsibility and shall not be liable to Tenant for any injury to or interference with Tenant’s business arising from the Renovations, nor shall Tenant be entitled to any compensation or damages from Landlord for loss of the use of the whole or any part of the Premises or of Tenant’s personal property or improvements resulting from the Renovations, or for any inconvenience or annoyance occasioned by such Renovations, provided that the foregoing shall not limit Landlord’s liability, if any, pursuant to applicable law for personal injury and property damage to the extent caused by the negligence or willful misconduct of Landlord, its agents, employees or contractors.

29.29 No Violation. Tenant hereby warrants and represents that neither its execution of nor performance under this Lease shall cause Tenant to be in violation of any agreement, instrument, contract, law, rule or regulation by which Tenant is bound, and Tenant shall protect, defend, indemnify and hold Landlord harmless against any claims, demands, losses, damages, liabilities, costs and expenses, including, without limitation, reasonable attorneys’ fees and costs, arising from Tenant’s breach of this warranty and representation.

SECTION 3

CONSTRUCTION DRAWINGS

3.1 Selection of Architect/Construction Drawings. Tenant shall select and retain the architect/space planner (the “Architect”), subject to Landlord’s approval, which approval shall not be unreasonably withheld, to prepare the Construction Drawings. Tenant shall retain the engineering consultants designated by Landlord (the “Engineers”) to prepare all plans and engineering working drawings relating to the structural, mechanical, electrical, plumbing, HVAC, life safety, and sprinkler work in the Premises; provided, that the Engineers agree to perform their services on commercially reasonable terms acceptable to Tenant, and specifically that the Engineers agree to perform their work in accordance with generally accepted standards of care in the Engineer’s profession, otherwise the engineers shall be selected by Tenant, subject to Landlord’s approval, which approval shall not be unreasonably withheld . At Tenant’s option it may select and retain a Certified Access Inspection specialist (hereinafter sometimes the “Consultant”) to assist in preparing the Construction Drawings. The plans and drawings to be prepared by Architect and the Engineers hereunder shall be known collectively as the “Construction Drawings”. All Construction Drawings shall comply with the drawing format and specifications reasonably determined by Landlord, and shall be subject to Landlord’s approval. Tenant and Architect shall verify, in the field, the dimensions and conditions as shown on the relevant portions of the base building plans, and Tenant and Architect shall be solely responsible for the same, and Landlord shall have no responsibility in connection therewith. Landlord’s review of the Construction Drawings as set forth in this Section 3, shall be for its sole purpose and shall not imply Landlord’s review of the same, or obligate Landlord to review the same, for quality, design, Code compliance or other like matters. Tenant acknowledges and agrees that the Construction Drawings shall provide for the improvements described in Schedule 1 attached to this Work Letter, all of which Landlord conceptually pre-approves as is evidenced by its execution of the Lease. Accordingly, notwithstanding that any Construction Drawings are reviewed by Landlord or its space planner, architect, engineers and consultants, and notwithstanding any advice or assistance which may be rendered to Tenant by Landlord or Landlord’s space planner, architect, engineers, and consultants, Landlord shall have no liability whatsoever in connection therewith and shall not be responsible for any omissions or errors contained in the Construction Drawings.

3.2 Final Space Plan. Tenant shall supply Landlord with four (4) copies signed by Tenant of its final space plan for the Premises before any architectural working drawings or engineering drawings have been commenced. The final space plan (the “Final Space Plan”) shall include a layout and designation of all offices, rooms and other partitioning, their intended use, and equipment to be contained therein. Landlord may request clarification or more specific drawings for special use items not included in the Final Space Plan. Landlord shall advise Tenant within five (5) business days after Landlord’s receipt of the Final Space Plan for the Premises that the same is either satisfactory or unsatisfactory (or incomplete), and if unsatisfactory or incomplete, describing what is necessary to make them satisfactory or complete with detail sufficient to enable the Architects and Engineers to make corrections. If Landlord fails to respond to Tenant within five (5) business days after Landlord’s receipt of the Final Space Plan for the Premises, Tenant shall send to Landlord written notice that Landlord failed to respond within such five (5) business days and this written notice shall contain the following statement: “IF LANDLORD FAILS TO TIMELY

EXHIBIT 1.1.1-2

-3-

RESPOND TO THIS NOTICE WITHIN TWO (2) BUSINESS DAYS AFTER ITS RECEIPT OF THIS NOTICE, THE FINAL SPACE PLAN SHALL BE DEEMED APPROVED UNLESS LANDLORD RESPONDS THAT THE SAME IS UNSATISFACTORY OR INCOMPLETE, DESCRIBING WHAT IS NECESSARY TO MAKE THEM SATISFACTORY OR COMPLETE WITH DETAIL SUFFICIENT TO ENABLE THE ARCHITECTS AND ENGINEERS TO MAKE CORRECTIONS.” If Tenant is so advised within the time provided as to what is necessary to make the Final Space Plan satisfactory or complete, Tenant shall promptly (i) cause the Final Space Plan to be revised to correct any deficiencies or other matters Landlord may reasonably require, and (ii) deliver such revised Final Space Plan to Landlord, and so long as the revised Final Space Plan reflects the corrections reasonably requested by Landlord, they shall be deemed approved.

3.3 Final Working Drawings. After the Final Space Plan has been approved by Landlord and Tenant, Tenant shall promptly cause the Architect and the Engineers to complete the architectural and engineering drawings for the Premises, and cause the Architect to compile a fully coordinated set of architectural, structural, mechanical, electrical and plumbing working drawings in a form which is complete to allow subcontractors to bid on the work and to obtain all applicable permits for the Tenant Improvements (collectively, the “Final Working Drawings”), and shall submit the same to Landlord for Landlord’s approval. Tenant shall supply Landlord with four (4) copies signed by Tenant of such Final Working Drawings. Landlord shall advise Tenant within five (5) business days after Landlord’s receipt of the Final Working Drawings for the Premises that the same is unsatisfactory or incomplete, and if unsatisfactory or incomplete, describing what is necessary to make them satisfactory or complete with detail sufficient to enable the Architects and Engineers to make corrections. If Landlord fails to respond to Tenant within five (5) business days after Landlord’s receipt of the Final Working Drawings, Tenant shall send to Landlord written notice that Landlord failed to respond within such five (5) business days and this written notice shall contain the following statement: “IF LANDLORD FAILS TO TIMELY RESPOND TO THIS NOTICE WITHIN TWO (2) BUSINESS DAYS AFTER ITS RECEIPT OF THIS NOTICE, THE FINAL WORKING DRAWINGS SHALL BE DEEMED APPROVED UNLESS LANDLORD RESPONDS THAT THE SAME IS UNSATISFACTORY OR INCOMPLETE, DESCRIBING WHAT IS NECESSARY TO MAKE THEM SATISFACTORY OR COMPLETE WITH DETAIL SUFFICIENT TO ENABLE THE ARCHITECTS AND ENGINEERS TO MAKE CORRECTIONS.” If Tenant is so advised within the time provided, Tenant shall promptly (i) revise the Final Working Drawings in accordance with such review and any reasonable disapproval of Landlord in connection therewith, and (ii) deliver such revised Final Working Drawings to Landlord, and so long as the Final Working Drawings reflect the corrections reasonably requested by Landlord, they shall be deemed approved.

3.4 Approved Working Drawings. Construction shall not commence until Landlord’s approval of the Final Working Drawings has been obtained (the “Approved Working Drawings”); provided, that any delay caused by Landlord in providing approval (defined as a Landlord Delay in Section 5.5.2 below) shall cause a corresponding extension in any deadlines to be met by Tenant herein to the extent provided for in Section 5.5.2 below. After approval by Landlord of the Final Working Drawings, Tenant shall promptly submit the same to the appropriate governmental authorities for all applicable building permits. Once submitted to the appropriate governmental authorities, the Approved Working Drawings shall be subject to such revisions and corrections as are required by the appropriate governmental authorities as a condition to issuance of permits, and all such required revisions and corrections shall be deemed to be approved by Landlord. Tenant hereby agrees that neither Landlord nor Landlord’s consultants shall be responsible for obtaining any building permit or certificate of occupancy for the Premises and that obtaining the same shall be Tenant’s responsibility; provided, however, that Landlord shall cooperate with Tenant in executing permit applications and performing other ministerial acts reasonably necessary to enable Tenant to obtain any such permit or certificate of occupancy. No changes, modifications or alterations in the Approved Working Drawings not required by the appropriate governmental authorities may be made without the prior written consent of Landlord, which consent shall not be unreasonably withheld; provided that Landlord may withhold its consent, in its sole discretion, to any change in the Approved Working Drawings, if such change would result in an Over-Allowance Cap (as defined below).

SECTION 4

CONSTRUCTION OF THE TENANT IMPROVEMENTS

4.1 Tenant’s Selection of Contractor and Tenant’s Agents.

4.1.1 The Contractor. A general contractor shall be retained by Tenant to construct the Tenant Improvements after conducting a competitive bidding process among JB Pacific and at least two (2) other general contractors proposed by Tenant and approved by Landlord. Based on Tenant’s evaluation of the bids submitted by the general contractors, Tenant shall deliver to Landlord notice of its selection of the winning bidder upon such selection. Tenant will enter into a contract with such contractor on commercially reasonable terms, and such contractor may be referred to as the “Contractor.”

All subcontractors, laborers, materialmen, and suppliers contracted by Tenant or the Contractor (such subcontractors, laborers, materialmen, and suppliers, and the Contractor to be known collectively as “Tenant’s Contractors”) must be approved in writing by Landlord, which approval shall not be unreasonably withheld or delayed. Prior to commencing the construction of the Tenant Improvements, Tenant will deliver true and correct copies of all of its contracts with the Contractors.

4.2 Construction of Tenant Improvements by Tenant’s Contractors.

If the Final Costs exceed the Tenant Improvement Allowance (less any portion thereof already disbursed by Landlord, or in the process of being disbursed by Landlord, on or before the commencement of construction of the Tenant Improvements), Tenant shall be liable for all excess costs. For the sake of clarity, if the City of San Diego, as a condition to issuing a building permit for the Tenant Improvements, requires any alterations to any portions of the Project Common Areas, Tenant shall not be liable for the costs associated with addressing any non-compliance with the ADA.

4.2.2 Tenant’s Contractors.

4.2.2.1 Landlord’s General Conditions for Tenant’s Contractors and Tenant Improvement Work. Tenant and Tenant’s Contractor’s construction of the Tenant Improvements shall comply with the following: (i) the Tenant Improvements shall be constructed in strict accordance with the Approved Working Drawings; (ii Tenant shall abide by all rules made by Landlord or its Building manager with respect to the use of freight, loading dock and service elevators, storage of materials, coordination of work with the contractors of other tenants, and any other matter in connection with this Work Letter, including, without limitation, the construction of the Tenant Improvements.

Tenant shall pay a logistical coordination fee (the “Coordination Fee”) to Landlord in an amount equal to the product of two percent (2%) of the Tenant Improvement Allowance; the Coordination Fee shall be for services relating to the coordination of the construction of the Tenant Improvements. In addition to the Coordination Fee and other amounts payable by Tenant hereunder, Tenant shall reimburse Landlord for amounts paid by Landlord in connection with the review of Tenant’s plans and drawings as referenced in Section 3 above, which amounts shall be charged against the Tenant Improvement Allowance.

4.2.2.3 Indemnity.

Such indemnity by Tenant, as set forth in the Lease, shall also apply with respect to any and all costs, losses, damages, injuries and liabilities related in any way to Landlord’s performance of any ministerial acts reasonably necessary (i) to permit Tenant to complete the Tenant Improvements, and (ii) to enable Tenant to obtain any building permit or certificate of occupancy for the Premises.

4.2.2.4.2 Special Coverages. Tenant shall carry “Builder’s All Risk” insurance in an amount approved by Landlord covering the construction of the Tenant Improvements, and such other insurance as Landlord may require, it being understood and agreed that the Tenant Improvements shall be insured by Tenant pursuant to the Lease immediately upon completion thereof. Such insurance shall be in amounts and shall include such extended coverage endorsements as may be reasonably required by Landlord, and in form and with companies as are required to be carried by Tenant as set forth in the Lease.

4.2.2.4.3 General Terms. Certificates for all insurance carried pursuant to this Section 4.2.2.4 shall be delivered to Landlord before the commencement of construction of the Tenant Improvements and before the Contractor’s equipment is moved onto the site. All such policies of insurance must contain a provision that the company writing said policy will give Landlord thirty (30) days’ prior written notice of any cancellation or lapse of the effective date or any reduction in the amounts of such insurance. In the event that the Tenant Improvements are damaged by any cause during the course of the construction thereof, Tenant shall immediately repair the same at Tenant’s sole cost and expense. All policies carried under this Section 4.2.2.4 shall insure Landlord and Tenant, as their interests may appear, as well as Contractor and Tenant’s Contractors, and shall name as additional insureds Landlord’s Property Manager, Landlord’s Asset Manager, and all mortgagees and ground lessors of the Building. All insurance, except Workers’ Compensation, maintained by Tenant’s Contractors shall preclude subrogation claims by the insurer against anyone insured thereunder. Such insurance shall provide that it is primary insurance as respects the owner and that any other insurance maintained by owner is excess and noncontributing with the insurance required hereunder. The requirements for the foregoing insurance shall not derogate from the provisions for indemnification of Landlord by Tenant under Section 4.2.2.3 of this Work Letter.

4.2.3 Governmental Compliance.

4.2.4 Inspection by Landlord. Landlord shall have the right to inspect the Tenant Improvements at all times, provided however, that Landlord’s failure to inspect the Tenant Improvements shall in no event constitute a waiver of any of Landlord’s rights hereunder nor shall Landlord’s inspection of the Tenant Improvements constitute Landlord’s approval of the same. Should Landlord disapprove any portion of the Tenant Improvements, Landlord shall notify Tenant in writing of such disapproval and shall specify the items disapproved. Any defects or deviations in the Tenant Improvements shall be rectified by Tenant at no expense to Landlord, provided however, that in the event Landlord reasonably determines that a defect or deviation exists or disapproves of any matter in connection with any portion of the Tenant Improvements and such defect, deviation or matter might adversely affect the mechanical, electrical, plumbing, heating, ventilating and air conditioning or life-safety systems of the Building, the structure or exterior appearance of the Building or any other tenant’s use of such other tenant’s leased premises, Landlord may, take such action as Landlord deems necessary, at Tenant’s expense and without incurring any liability on Landlord’s part, to correct any such defect, deviation and/or matter, including, without limitation, causing the cessation of performance of the construction of the Tenant Improvements until such time as the defect, deviation and/or matter is corrected to Landlord’s satisfaction.

In addition, Tenant’s inability to obtain any custom-made or other than customary materials or supplies shall in no event constitute a Force Majeure Delay.

5.5.2 “Landlord Delays”, as such term may be used in the Lease or in this Work Letter, shall mean any actual delay in the completion of the Tenant Improvement which are due to any act or omission of Landlord, its agents or contractors and shall be limited to the following: (i) delays in the giving of authorizations or approvals by Landlord as required by this Work Letter, (ii) delays due to the acts or failure to act of Landlord, its agents or contractors, where such acts or failures to act actually delay the completion of the Tenant Improvements, provided that Tenant acts in a commercially reasonable manner to mitigate (provided that the cost of any such mitigation measures shall be borne by Landlord) any such delay, and (iii) delays due to the interference of Landlord, its agents or contractors, with the completion of the Tenant Improvements or the failure or refusal of any party thereof to permit Tenant, its agents and contractors, access to and use of the building or any Building facilities or services which are required for the orderly and continuous performance of the work necessary to complete the Tenant Improvements.
