ARTICLE 2

TERM/PREMISES

The Term of this Lease shall commence on the Commencement Date as set forth in Article 1.A. of the Basic Lease Provisions and shall end on the Expiration Date set forth in Article 1.A. of the Basic Lease Provisions. For purposes of this Lease, the term “Lease Year” shall mean each consecutive twelve (12) month period during the Term, with the first (1st) Lease Year commencing on the Commencement Date; however, (a) if the Commencement Date falls on a day other than the first (1^st) day of a calendar month, the first (1^st) Lease Year shall end on the last day of the eleventh (11^th) month after the Commencement Date and the second (2^nd) and each succeeding Lease Year shall commence on the first (1^st) day of the next calendar month, and (b) the last Lease Year shall end on the Expiration Date. If Landlord does not deliver possession of the Premises to Tenant on or before the anticipated Commencement Date (as set forth in Article 1.A, above), Landlord shall not be subject to any liability for its failure to do so, and such failure shall not affect the validity of this Lease nor the obligations of Tenant hereunder. Landlord and Tenant hereby stipulate that the Premises contains the number of square feet specified in Article 1.B. of the Basic Lease Provisions. After the Commencement Date, Landlord may deliver to Tenant a Commencement Letter in a form substantially similar to that attached hereto as Exhibit “C”, which Tenant shall execute and return to Landlord within five (5) days of receipt thereof. Failure of Tenant to timely execute and deliver the Commencement Letter shall constitute acknowledgment by Tenant that the statements included in such notice are true and correct, without exception.

ARTICLE 3

RENTAL

(a) Basic Rental. Tenant agrees to pay to Landlord during the Term hereof, at Landlord’s office or to such other person or at such other place as directed from time to time by written notice to Tenant from Landlord, the monthly and annual sums as set forth in Article 1.C. of the Basic Lease Provisions, payable in advance on the first (1^st) day of each calendar month, without demand, setoff or deduction, and in the event this Lease commences or the date of expiration of this Lease occurs other than on the first (1^st) day or last day of a calendar month, the rent for such month shall be prorated. Notwithstanding the foregoing, the first full month’s Basic Rental shall be paid to Landlord in accordance with Article 1.K. of the Basic Lease Provisions and, if the Commencement Date is not the first day of a month, Basic Rental for the partial month commencing as of the Commencement Date shall be prorated based upon the actual number of days in such month and shall be due and payable upon the Commencement Date.

(b) Increase in Direct Costs. The term “Base Year” means the calendar year set forth in Article 1.D. of the Basic Lease Provisions. If, in any calendar year during the Term of this Lease commencing with the calendar year 2015, the “Direct Costs” (as hereinafter defined) paid or incurred by Landlord shall be higher than the Direct Costs for the Base Year, Tenant shall pay

-2-

an additional sum for each such subsequent calendar year equal to the product of the amount set forth in Article 1.E. of the Basic Lease Provisions multiplied by such increased amount of “Direct Costs.” In the event either the Premises and/or the Project is expanded or reduced, then Tenant’s Proportionate Share shall be appropriately adjusted, and as to the calendar year in which such change occurs, Tenant’s Proportionate Share for such calendar year shall be determined on the basis of the number of days during that particular calendar year that such Tenant’s Proportionate Share was in effect. In the event this Lease shall terminate on any date other than the last day of a calendar year, the additional sum payable hereunder by Tenant during the calendar year in which this Lease terminates shall be prorated on the basis of the relationship which the number of days which have elapsed from the commencement of said calendar year to and including said date on which this Lease terminates bears to three hundred sixty five (365). Any and all amounts due and payable by Tenant pursuant to this Lease (other than Basic Rental) shall be deemed “Additional Rent” and Landlord shall be entitled to exercise the same rights and remedies upon default in these payments as Landlord is entitled to exercise with respect to defaults in monthly Basic Rental payments. Any and all amounts due and payable by Tenant to Landlord shall be in the form of (i) business checks, (ii) wire transfers, (iii) electronic funds transfers, and (iv) automated clearing house payments. Any other forms of payment are not acceptable to Landlord including, without limitation (1) cash or currency, (2) cashier’s checks and money orders, (3) traveler’s checks, (4) payments from credit unions or other non-bank financial institutions, (5) multiple payments for one (1) scheduled payment, and (6) third party checks.

(c) Definitions. As used herein the term “Direct Costs” shall mean the sum of the following:

(i) “Tax Costs”, which shall mean any and all real estate taxes and other similar charges on real property or improvements, assessments, water and sewer charges, and all other charges assessed, reassessed or levied upon the Project and appurtenances thereto and the parking or other facilities thereof, or the real property thereunder (collectively the “Real Property”) or attributable thereto or on the rents, issues, profits or income received or derived therefrom which are assessed, reassessed or levied by the United States, the State of California or any local government authority or agency or any political subdivision thereof, and shall include Landlord’s reasonable legal fees, costs and disbursements incurred in connection with proceedings for reduction of Tax Costs or any part thereof; provided, however, if at any time after the date of this Lease the methods of taxation now prevailing shall be altered so that in lieu of or as a supplement to or a substitute for the whole or any part of any Tax Costs, there shall be assessed, reassessed or levied (a) a tax, assessment, reassessment, levy, imposition or charge wholly or partially as a net income, capital or franchise levy or otherwise on the rents, issues, profits or income derived therefrom, or (b) a tax, assessment, reassessment, levy (including but not limited to any municipal, state or federal levy), imposition or charge measured by or based in whole or in part upon the Real Property and imposed upon Landlord, then except to the extent such items are payable by Tenant under Article 6 below, such taxes, assessments, reassessments or levies or the part thereof so measured or based, shall be deemed to be included in the term “Direct Costs.” In addition, when calculating Tax Costs for the Base Year, special assessments shall only be deemed included in Tax Costs for the Base Year to the extent that such special assessments are included in Tax Costs for the applicable subsequent calendar year during the Term.

(ii) “Operating Costs”, which shall mean all costs and expenses incurred by Landlord in connection with the maintenance, operation, replacement, ownership and repair of the Project, the equipment, the intrabuilding cabling and wiring, adjacent walks, malls and landscaped and common areas and the parking structure, areas and facilities of the Project. Operating Costs shall include but not be limited to, salaries, wages, medical, surgical and general welfare benefits and pension payments, payroll taxes, fringe benefits, employment taxes, workers’ compensation, uniforms and dry cleaning thereof for all persons who perform duties connected with the operation, maintenance and repair of the Project, its equipment, the intrabuilding cabling and wiring and the adjacent walks and landscaped areas, including janitorial, gardening, security, parking, operating engineer, elevator, painting, plumbing, electrical, carpentry, heating, ventilation, air conditioning and window washing; hired services; a reasonable allowance for depreciation of the cost of acquiring or the rental expense of personal property used in the maintenance, operation and repair of the Project; accountant’s fees incurred in the preparation of rent adjustment statements; legal fees; real estate tax consulting fees; personal property taxes on property used in the maintenance and operation of the Project; fees,

-3-

costs, expenses or dues payable pursuant to the terms of any covenants, conditions or restrictions or owners’ association pertaining to the Project; capital expenditures incurred to effect economies of operation of, or stability of services to, the Project and capital expenditures required by government regulations, laws, or ordinances including, but not limited to the Americans with Disabilities Act; provided, however, that capital expenditures included in Operating Costs shall be amortized (with interest at eight percent (8%) per annum) over its useful life; the cost of all charges for gas and water furnished to the Project (including, without limitation, costs incurred in connection with Landlord’s supplying of “green” or other renewable utilities), and any taxes thereon; the cost of all charges for electricity furnished to the common areas of the Project (including, without limitation, costs incurred in connection with Landlord’s supplying of “green” or other renewable energy, but excluding any electricity furnished to other tenants of the Project), and any taxes thereon; the cost of all charges for fire and extended coverage, liability and all other insurance in connection with the Project carried by Landlord; the cost of all building and cleaning supplies and materials; the cost of all charges for cleaning, maintenance and service contracts and other services with independent contractors and administration fees; a property management fee (which fee may be imputed if Landlord has internalized management or otherwise acts as its own property manager) and license, permit and inspection fees relating to the Project. In the event, during any calendar year (including the Base Year), the Project is less than ninety-five percent (95%) occupied at all times, Operating Costs shall be adjusted to reflect the Operating Costs of the Project as though ninety-five percent (95%) were occupied at all times, and the increase or decrease in the sums owed hereunder shall be based upon such Operating Costs as so adjusted. Notwithstanding anything to the contrary set forth in this Article 3, when calculating Operating Costs for the Base Year, unless Operating Costs for the applicable subsequent calendar year include the applicable following items, Operating Costs shall exclude (a) increases due to extraordinary circumstances including, but not limited to, labor-related boycotts and strikes, utility rate hikes, utility conservation surcharges, or other surcharges, insurance premiums resulting from terrorism coverage, catastrophic events and/or the management of environmental risks, and (b) amortization of any capital items including, but not limited to, capital improvements, capital repairs and capital replacements (including such amortized costs where the actual improvement, repair or replacement was made in prior years).

Notwithstanding anything above to the contrary, Operating Costs shall not include (1) the cost of providing electricity to any other tenants of the Project or the cost of providing any other service directly to and paid directly by any tenant (outside of such tenant’s Direct Cost payments) such as where a tenant directly contracts for utilities with the local utility company, provided that in each such case, Landlord shall have the right to “gross up” such item (other than electricity) as if such space was vacant; (2) the cost of any items for which Landlord is reimbursed by insurance proceeds, condemnation awards, a tenant of the Project (outside of such tenant’s Direct Cost payments), or otherwise to the extent so reimbursed; (3) any real estate brokerage commissions or other costs incurred in procuring tenants, or any fee in lieu of commission; (4) amortization of principal and interest on mortgages or ground lease payments (if any); (5) costs of items considered capital repairs, replacements, improvements and equipment under generally accepted accounting principles consistently applied except as expressly included in Operating Costs pursuant to the definition above; (6) costs incurred by Landlord due to the violation by Landlord or any tenant of the terms and conditions of any lease of space in the Project or any law, code, regulation, ordinance or the like; (7) any compensation paid to clerks, attendants or other persons in commercial concessions operated by Landlord (other than in the parking facility for the Project); (8) costs incurred in connection with upgrading the Project to comply with disability, life, seismic, fire and safety codes, ordinances, statutes, or other laws in effect prior to the Commencement Date, including, without limitation, the then applicable requirements of the Americans with Disabilities Act (“ADA”), including penalties or damages incurred due to such non-compliance; (9) bad debt expenses and interest, principal, points and fees on debts (except in connection with the financing of items which may be included in Operating Costs); (10) marketing costs, including those costs described in (3) above, attorneys’ fees in connection with the negotiation and preparation of letters, deal memos, letters of intent, leases, subleases and/or assignments, space planning costs, and other costs and expenses incurred in connection with lease, sublease and/or assignment negotiations and transactions with present or prospective tenants or other occupants of the Project, including attorneys’ fees and other costs and expenditures incurred in connection with disputes with present or prospective tenants or other occupants of the Project; (11) costs, including permit, license and inspection costs, incurred with respect to the installation of other tenants’ or occupants’ improvements made for tenants or other occupants in the Project or incurred in renovating or otherwise improving, decorating,

-4-

painting or redecorating vacant space for tenants or other occupants in the Project; (12) any costs expressly excluded from Operating Costs elsewhere in this Lease; (13) costs of any items (including, but not limited to, costs incurred by Landlord for the repair of damage to the Project) to the extent Landlord receives reimbursement from insurance proceeds or from a third party (except that any deductible amount under any insurance policy shall be included within Operating Costs); (14) rentals and other related expenses for leasing an HVAC system, elevators, or other items (except when needed in connection with normal repairs and maintenance of the Project) which if purchased, rather than rented, would constitute a capital improvement not included in Operating Costs pursuant to this Lease; (15) depreciation, amortization and interest payments, except as specifically included in Operating Costs pursuant to the terms of this Lease and except on materials, tools, supplies and vendor-type equipment purchased by Landlord to enable Landlord to supply services Landlord might otherwise contract for with a third party, where such depreciation, amortization and interest payments would otherwise have been included in the charge for such third party’s services, all as determined in accordance with generally accepted accounting principles, consistently applied, and when depreciation or amortization is permitted or required, the item shall be amortized over its reasonably anticipated useful life; (16) expenses in connection with services or other benefits which are not offered to Tenant or for which Tenant is charged for directly but which are provided to another tenant or occupant of the Project, without charge; (17) costs incurred in connection with the operation of retail stores selling merchandise and restaurants in the Project to the extent such costs are in excess of the costs Landlord reasonably estimates would have been incurred had such space been used for general office use; (18) costs (including in connection therewith all attorneys’ fees and costs of settlement, judgments and/or payments in lieu thereof) arising from claims, disputes or potential disputes in connection with potential or actual claims litigation or arbitrations pertaining to Landlord and/or the Project, other than such claims or disputes respecting any services or equipment used in the operation of the Project by Landlord; (19) costs associated with the operation of the business of the partnership which constitutes Landlord as the same are distinguished from the costs of operation of the Project; (20) costs incurred in connection with the original construction of the Project; (21) costs of correcting defects in or inadequacy of the initial design or construction of the Project; and (22) costs incurred to (i) comply with laws relating to the removal of any “Hazardous Material,” as that term is defined in Article 28 of this Lease, which was in existence on the Project prior to the Commencement Date, and was of such a nature that a federal, state or municipal governmental authority, if it had then had knowledge of the presence of such Hazardous Material, in the state, and under the conditions that it then existed on the Project, would have then required the removal of such Hazardous Material or other remedial or containment action with respect thereto, and (ii) remove, remedy, contain, or treat any Hazardous Material, which Hazardous Material is brought onto the Project after the date hereof by Landlord or any other tenant of the Project and is of such a nature, at that time, that a federal, state or municipal governmental authority, if it had then had knowledge of the presence of such Hazardous Material, in the state, and under the conditions, that it then exists on the Project, would have then required the removal of such Hazardous Material or other remedial or containment action with respect thereto.

In addition, notwithstanding anything to the contrary contained herein, the aggregate Controllable Operating Costs, as that term is defined below, shall not increase more than six percent (6%) in any calendar year over the maximum amount of Controllable Operating Costs chargeable for the immediately preceding calendar year, with no limit on the Controllable Operating Costs during the Base Year (i.e., the actual Controllable Operating Costs for the Base Year shall be the maximum amount for the Base Year for purposes of this provision). “Controllable Operating Costs” shall mean wages, salaries and other compensation and benefits paid to Landlord’s non-union employees engaged in the operation, management, maintenance or security of the Project, any management fee paid to any affiliate of Landlord and any rental paid for any management office of the Project.

(d) Determination of Payment.

(i) If for any calendar year ending or commencing within the Term, Tenant’s Proportionate Share of Direct Costs for such calendar year exceeds Tenant’s Proportionate Share of Direct Costs for the Base Year, then Tenant shall pay to Landlord, in the manner set forth in Sections 3(d)(ii) and (iii), below, and as Additional Rent, an amount equal to the excess (the “Excess”).

-5-

(ii) Landlord shall 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 Costs for the then-current calendar year shall be and the estimated Excess (the “Estimated Excess”) as calculated by comparing Tenant’s Proportionate Share of Direct Costs for such calendar year, which shall be based upon the Estimate, to Tenant’s Proportionate Share of Direct Costs for the Base Year. The failure of Landlord to timely furnish the Estimate Statement for any calendar year shall not preclude Landlord from subsequently enforcing its rights to collect any Estimated Excess under this Article 3, once such Estimated Excess has been determined by Landlord. If pursuant to the Estimate Statement an Estimated Excess is calculated for the then-current calendar year, Tenant shall pay, with its next installment of Monthly Basic Rental due, a fraction of the Estimated Excess for the then-current calendar year (reduced by any amounts paid pursuant to the last sentence of this Section 3(d)(ii)). Such fraction shall have as its numerator the number of months which have elapsed in such current calendar year to the month of such payment, both months inclusive, and shall have twelve (12) as its denominator. Until a new Estimate Statement is furnished, Tenant shall pay monthly, with the Monthly Basic Rental installments, an amount equal to one-twelfth (1/12^th) of the total Estimated Excess set forth in the previous Estimate Statement delivered by Landlord to Tenant.

(iii) In addition, Landlord shall endeavor to give to Tenant as soon as reasonably practicable following the end of each calendar year, a statement (the “Statement”) which shall state the Direct Costs incurred or accrued for such preceding calendar year, and which shall indicate the amount, if any, of the Excess. Upon receipt of the Statement for each calendar year during the Term, if amounts paid by Tenant as Estimated Excess are less than the actual Excess as specified on the Statement, Tenant shall pay, with its next installment of monthly Basic Rental due, the full amount of the Excess for such calendar year, less the amounts, if any, paid during such calendar year as Estimated Excess. If, however, the Statement indicates that amounts paid by Tenant as Estimated Excess are greater than the actual Excess as specified on the Statement, such overpayment shall be credited against Tenant’s next installments of Estimated Excess. The failure of Landlord to timely furnish the Statement for any calendar year shall not prejudice Landlord from enforcing its rights under this Article 3, once such Statement has been delivered. Even though the Term has expired and Tenant has vacated the Premises, when the final determination is made of Tenant’s Proportionate Share of the Direct Costs for the calendar year in which this Lease terminates, if an Excess is present, Tenant shall immediately pay to Landlord an amount as calculated pursuant to the provisions of this Section 3(d). The provisions of this Section 3(d)(iii) shall survive the expiration or earlier termination of the Term.

(iv) If the Project is a part of a multi-building development, those Direct Costs attributable to such development as a whole (and not attributable solely to any individual building therein) shall be allocated by Landlord to the Project and to the other buildings within such development on an equitable basis.

(e) Audit Right. Within one hundred twenty (120) days after receipt of a Statement by Tenant (“Review Period”), if Tenant disputes the amount set forth in the Statement, Tenant’s employees or an independent certified public accountant (which accountant is a member of a nationally or regionally recognized accounting firm and is not retained on a contingency fee basis), designated by Tenant, may, after reasonable notice to Landlord (“Review Notice”) and at reasonable times, inspect Landlord’s records at Landlord’s offices, provided that Tenant is not then in default after expiration of all applicable cure periods and provided further that Tenant and such accountant or representative shall, and each of them shall use their commercially reasonable efforts to cause their respective agents and employees to, maintain all information contained in Landlord’s records in strict confidence. Notwithstanding the foregoing, Tenant shall only have the right to review Landlord’s records one (1) time during any twelve (12) month period. If after such inspection, but within thirty (30) days after the Review Period, Tenant notifies Landlord in writing (“Dispute Notice”) that Tenant still disputes such amounts, a certification as to the proper amount shall be made in accordance with Landlord’s standard accounting practices, at Tenant’s expense, by an independent certified public accountant selected by Landlord and who is a member of a nationally or regionally recognized accounting firm. Tenant’s failure to deliver the Review Notice within the Review Period or to deliver the Dispute Notice within thirty (30) days after the Review Period shall be deemed to constitute Tenant’s approval of such Statement and Tenant, thereafter, waives the right or ability to dispute the amounts set forth in such Statement. If Tenant timely delivers the Review Notice and the Dispute Notice, Landlord shall cooperate in good faith with Tenant and the accountant to show Tenant and the accountant the

-6-

information upon which the certification is to be based. However, if such certification by the accountant proves that the Direct Costs set forth in the Statement were overstated by more than ten percent (10%), then the cost of the accountant and the cost of such certification shall be paid for by Landlord. Promptly following the parties receipt of such certification, the parties shall make such appropriate payments or reimbursements, as the case may be, to each other, as are determined to be owing pursuant to such certification. Tenant agrees that this section shall be the sole method to be used by Tenant to dispute the amount of any Direct Costs payable by Tenant pursuant to the terms of this Lease, and Tenant hereby waives any other rights at law or in equity relating thereto.

ARTICLE 4

CASH SECURITY DEPOSIT/LETTER OF CREDIT

(a) Cash Security Deposit. Tenant has deposited or concurrently herewith is depositing with Landlord the sum set forth in Article 1.F. of the Basic Lease Provisions as security for the full and faithful performance of every provision of this Lease to be performed by Tenant. If Tenant breaches any provision of this Lease, including but not limited to the payment of rent, Landlord may use all or any part of this cash security deposit for the payment of any rent or any other sums in default, or to compensate Landlord for any other loss or damage which Landlord may suffer by reason of Tenant’s default. If any portion of said deposit is so used or applied, Tenant shall, within five (5) days after written demand therefor, deposit funds with Landlord in a form acceptable under Section 3(b) above and in an amount sufficient to restore the cash security deposit to its full amount. Tenant agrees that Landlord shall not be required to keep the cash security deposit in trust, segregate it or keep it separate from Landlord’s general funds, but Landlord may commingle the cash security deposit with its general funds and Tenant shall not be entitled to interest on such deposit. At the expiration of the Term, and provided there exists no default by Tenant hereunder, the cash security deposit or any balance thereof shall be returned to Tenant (or, at Landlord’s option, to Tenant’s “Transferee”, as such term is defined in Article 15 below), provided that subsequent to the expiration of this Lease, Landlord may retain from said cash security deposit (i) an amount reasonably estimated by Landlord to cover potential Direct Cost reconciliation payments due with respect to the calendar year in which this Lease terminates or expires (such amount so retained shall not, in any event, exceed ten percent (10%) of estimated Direct Cost payments due from Tenant for such calendar year through the date of expiration or earlier termination of this Lease and any amounts so retained and not applied to such reconciliation shall be returned to Tenant within thirty (30) days after Landlord’s delivery of the Statement for such calendar year), (ii) any and all amounts reasonably estimated by Landlord to cover the anticipated costs to be incurred by Landlord to remove any signage provided to Tenant under this Lease, to remove cabling and other items required to be removed by Tenant under Section 29(b) below and to repair any damage caused by such removal (in which case any excess amount so retained by Landlord shall be returned to Tenant within thirty (30) days after such removal and repair), and (iii) any and all amounts permitted by law or this Section 4(a). Tenant hereby waives the provisions of Section 1950.7 of the California Civil Code and all other provisions of law, now or hereafter in effect, which provide that Landlord may claim from a cash security deposit only those sums reasonably necessary to remedy defaults in the payment of rent, to repair damage caused by Tenant or to clean the Premises, it being agreed that Landlord may, in addition, claim those sums specified in this Section 4(a) above, and all of Landlord’s damages under this Lease and California law including, but not limited to, any damages accruing upon termination of this Lease under Section 1951.2 of the California Civil Code and/or those sums reasonably necessary to compensate Landlord for any other loss or damage, foreseeable or unforeseeable, caused by the acts or omissions of Tenant or any officer, employee, agent, contractor or invitee of Tenant. Notwithstanding anything to the contrary contained in this Section 4(a), in the event that Tenant, at the expiration of the twenty-fourth (24^th), twenty-eighth (28^th), thirty-second (32^nd) and/or thirty-sixth (36^th) full calendar months of the initial Lease Term, is not in default of any of its obligations under this Lease (or if Tenant is then in default, upon Tenant’s cure of such default), Landlord shall reduce the amount of the cash security deposit by the amount of the monthly Basic Rental due and payable to Landlord for the next full calendar month(s) of the initial Lease Term, respectively, and Landlord shall apply such amounts against Tenant’s monthly Basic Rental obligation for such next full calendar month(s).

(b) Letter of Credit.

(i) Stated Amount. Within ten (10) days after Tenant’s execution and delivery of this Lease, Tenant shall deliver to Landlord an unconditional, irrevocable and

-7-

renewable letter of credit (“Letter of Credit”) in favor of Landlord in the form attached hereto as Exhibit E, issued by a financial institution satisfactory to Landlord, in the principal amount (“Stated Amount”) specified below, to be held by Landlord in accordance with the terms, provisions and conditions of this Lease. Tenant shall pay all expenses, points and/or fees incurred by Tenant in obtaining the Letter of Credit. If the Letter of Credit delivered by Tenant is inconsistent with the form attached hereto as Exhibit E (including, without limitation, the wrong name or address for the Beneficiary), Landlord may so notify Tenant in writing, in which case Tenant shall cause the Letter of Credit to be corrected within five (5) business days after such notice. Landlord shall be entitled to draw upon the Letter of Credit if the credit rating or financial condition of the issuer of the Letter of Credit is no longer reasonably acceptable to Landlord. Following any such draw by Landlord on the Letter of Credit solely because of the deterioration of the creditworthiness of the issuer of the Letter of Credit, Landlord will disburse such Letter of Credit proceeds to Tenant provided (A) Tenant delivers to Landlord a replacement Letter of Credit from a financial institution satisfactory to Landlord in the form attached hereto as Exhibit “E” within sixty (60) days after Landlord’s draw thereon, (B) there exists no event of default with respect to any provision of this Lease, and (C) Tenant pays all of Landlord’s fees and expenses incurred in connection with such disbursement; provided, however, if any of the three (3) foregoing conditions are not satisfied, the proceeds received from such draw shall constitute Landlord’s property (and not Tenant’s property or the property of the bankruptcy estate of Tenant) and Landlord may then use, apply or retain all or any part of the proceeds for the purposes set forth in clauses (1) through (5) of the next paragraph. The Stated Amount shall initially be One Hundred Fifty Thousand Dollars ($150,000.00); provided, however, that, except as hereinafter provided, upon the last day of the thirty-sixth (36^th) month of the initial Term (the “Letter of Credit Return Date”), Landlord shall return the Letter of Credit to Tenant and this Section 4(b) shall be of no further force and effect. However, if (i) a default by Tenant occurs under this Lease, or (ii) circumstances exist that would, with notice or lapse of time, or both, constitute a default by Tenant, and in the case of (i) or (ii) Tenant has failed to cure such default within the time period permitted by Article 19 or such lesser time as may remain before the Letter of Credit Return Date as provided above, the Letter of Credit shall not be returned to Tenant and this Section 4(b) shall continue to be in force and effect, unless and until such default shall have been fully cured pursuant to the terms of this Lease, at which time Landlord shall return to Tenant the Letter of Credit and this Section 4(b) shall be of no further force and effect as hereinabove described.

(ii) Demands on Letter of Credit. The Letter of Credit shall state that an authorized officer or other representative of Landlord may make demand on Landlord’s behalf for the Stated Amount of the Letter of Credit, or any portion thereof, and that the issuing bank must immediately honor such demand, without qualification or satisfaction of any conditions, except the proper identification of the party making such demand. In addition, the Letter of Credit shall indicate that it is transferable in its entirety by Landlord as beneficiary and that upon receiving written notice of transfer, and upon presentation to the issuing bank of the original Letter of Credit, the issuer or confirming bank will reissue the Letter of Credit naming such transferee as the beneficiary. Tenant shall be responsible for the payment to the issuing bank of any transfer costs imposed by the issuing bank in connection with any such transfer. If (A) the term of the Letter of Credit held by Landlord will expire prior to the last day of the Lease Term and the Letter of Credit is not extended, or a new Letter of Credit for an extended period of time is not substituted, in either case at least sixty (60) days prior to the expiration of the Letter of Credit, or (B) Tenant commits a default with respect to any provision of this Lease, which is not cured within any applicable cure period, including the filing of a voluntary petition under Title 11 of the United States Code (i.e., the Bankruptcy Code), or otherwise becomes a debtor in any case or proceeding under the Bankruptcy Code, as now existing or hereinafter amended, or any similar law or statute, Landlord may (but shall not be required to) draw upon all or any portion of the Stated Amount of the Letter of Credit, and the proceeds received from such draw shall constitute Landlord’s property (and not Tenant’s property or the property of the bankruptcy estate of Tenant) and Landlord may then use, apply or retain all or any part of the proceeds (1) for the payment of any sum which is in default, (2) to reimburse Landlord for costs incurred by Landlord in connection with this Lease (including, without limitation, any costs incurred by Landlord to improve the Premises, and any brokerage commissions and attorneys’ fees), (3) for the payment of any other amount which Landlord may spend or become obligated to spend by reason of Tenant’s default, (4) to compensate Landlord for any loss or damage which Landlord may suffer by reason of Tenant’s default or (5) as prepaid rent to be applied against Tenant’s Basic Rental obligations for the last month of the Term and the immediately preceding month(s)

-8-

of the Term until the remaining proceeds are exhausted. If any portion of the Letter of Credit proceeds are so used or applied, Tenant shall, within ten (10) days after demand therefor, post an additional Letter of Credit in an amount to cause the aggregate amount of the unused proceeds and such new Letter of Credit to equal the Stated Amount required in Section 4(b)(i) above. Landlord shall not be required to keep any proceeds from the Letter of Credit separate from its general funds. Should Landlord sell its interest in the Premises during the Lease Term and if Landlord deposits with the purchaser thereof the Letter of Credit or any proceeds of the Letter of Credit, thereupon Landlord shall be discharged from any further liability with respect to the Letter of Credit and said proceeds and Tenant shall look solely to such transferee for the return of the Letter of Credit or any proceeds therefrom.

(iii) Reservation of Rights. The use, application or retention of the Letter of Credit, the proceeds or any portion thereof, shall not prevent Landlord from exercising any other rights or remedies provided under this Lease, it being intended that Landlord shall not be required to proceed against the Letter of Credit, and such use, application or retention of the Letter of Credit shall not operate as a limitation on any recovery to which Landlord may otherwise be entitled. No trust relationship is created herein between Landlord and Tenant with respect to the Letter of Credit.

(iv) Waiver of Security Deposit Laws. Landlord and Tenant acknowledge and agree that in no event or circumstance shall the Letter of Credit, any renewal thereof or substitute therefor or the proceeds thereof be (i) deemed to be or treated as a “security deposit” within the meaning of California Civil Code Section 1950.7, (ii) subject to the terms of such Section 1950.7, or (iii) intended to serve as a “security deposit” within the meaning of such Section 1950.7. The parties hereto (A) recite that the Letter of Credit is not intended to serve as a security deposit and such Section 1950.7 and any and all other laws, rules and regulations applicable to security deposits in the commercial context (“Security Deposit Laws”) shall have no applicability or relevancy thereto and (B) waive any and all rights, duties and obligations either party may now or, in the future, will have relating to or arising from the Security Deposit Laws. Notwithstanding the foregoing, to the extent California Civil Code Section 1950.7 in any way: (a) is applicable to this Lease or the Letter of Credit (or any proceeds thereof); or (b) controls Landlord’s rights to draw on the Letter of Credit or apply the proceeds of the Letter of Credit to any amounts due under the Lease or any damages Landlord may suffer following termination of this Lease, then Tenant fully and irrevocably waives the benefits and protections of Section 1950.7 of the California Civil Code, it being agreed that Landlord may recover from the Letter of Credit (or its proceeds) all of Landlord’s damages under this Lease and California law including, but not limited to, any damages accruing upon the termination of this Lease in accordance with this Lease and Section 1951.2 of the California Civil Code.

ARTICLE 5

HOLDING OVER

Should Tenant (or any subtenant, assignee or other party occupying the Premises by, through, under, or with the permission of Tenant), without Landlord’s written consent, hold over after termination of this Lease, Tenant shall, at Landlord’s option, become either a tenant at sufferance or a month-to-month tenant upon each and all of the terms herein provided as may be applicable to such a tenancy and any such holding over shall not constitute an extension of this Lease. During such holding over, Tenant shall pay in advance, monthly, Basic Rental at a rate equal to one hundred fifty percent (150%) of the rate in effect for the last month of the Term of this Lease, in addition to, and not in lieu of, all other payments required to be made by Tenant hereunder including but not limited to Tenant’s Proportionate Share of any increase in Direct Costs. Nothing contained in this Article 5 shall be construed as consent by Landlord to any holding over of the Premises 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 earlier termination of the Term. If Tenant fails to surrender the Premises upon the expiration or termination of this Lease, Tenant agrees to indemnify, defend and hold Landlord harmless from and against all costs, loss, expense or liability, including without limitation, claims made by any succeeding tenant and real estate brokers claims and attorney’s fees and costs.

-9-

ARTICLE 6

OTHER TAXES

Tenant shall pay, prior to delinquency, all taxes assessed against or levied upon trade fixtures, furnishings, equipment and all other personal property of Tenant located in the Premises. In the event any or all of Tenant’s trade fixtures, furnishings, equipment and other personal property shall be assessed and taxed with property of Landlord, or if the cost or value of any leasehold improvements in the Premises exceeds the cost or value of a Project-standard buildout as determined by Landlord and, as a result, real property taxes for the Project are increased, Tenant shall pay to Landlord, within ten (10) days after delivery to Tenant by Landlord of a written statement setting forth such amount, the amount of such taxes applicable to Tenant’s property or above-standard improvements. Tenant shall assume and pay to Landlord at the time Basic Rental next becomes due (or if assessed after the expiration of the Term, then within ten (10) days), any excise, sales, use, rent, occupancy, garage, parking, gross receipts or other taxes (other than net income taxes) which may be assessed against or levied upon Landlord on account of the letting of the Premises or the payment of Basic Rental or any other sums due or payable hereunder, and which Landlord may be required to pay or collect under any law now in effect or hereafter enacted. In addition to Tenant’s obligation pursuant to the immediately preceding sentence, Tenant shall pay directly to the party or entity entitled thereto all business license fees, gross receipts taxes and similar taxes and impositions which may from time to time be assessed against or levied upon Tenant, as and when the same become due and before delinquency. Notwithstanding anything to the contrary contained herein, any sums payable by Tenant under this Article 6 shall not be included in the computation of “Tax Costs.”

ARTICLE 7

USE

Tenant shall use and occupy the Premises only for the use set forth in Article 1.H. of the Basic Lease Provisions and shall not use or occupy the Premises or permit the same to be used or occupied for any other purpose without the prior written consent of Landlord, which consent may be given or withheld in Landlord’s sole and absolute discretion, and Tenant agrees that it will use the Premises in such a manner so as not to interfere with or infringe upon the rights of other tenants or occupants in the Project. Tenant shall, at its sole cost and expense, promptly comply with all laws, statutes, ordinances, governmental regulations or requirements now in force or which may hereafter be in force relating to or affecting (i) the condition, use or occupancy of the Premises or the Project (excluding structural changes to the Project not related to Tenant’s particular use of the Premises), and (ii) improvements installed or constructed in the Premises by or for the benefit of Tenant. Tenant shall not permit more than six (6) people per one thousand (1,000) rentable square feet of the Premises to occupy the Premises at any time. Tenant shall not do or permit to be done anything which would invalidate or increase the cost of any insurance policy covering the Project and/or the property located therein and Tenant shall comply with all rules, orders, regulations and requirements of any organization which sets out standards, requirements or recommendations commonly referred to by major fire insurance underwriters, and Tenant shall promptly upon demand reimburse Landlord for any additional premium charges for any such insurance policy assessed or increased by reason of Tenant’s failure to comply with the provisions of this Article 7. Tenant shall comply with Landlord’s reasonable sustainability practices and shall not permit any use of the Premises which may affect the continued certification of the Project issued pursuant to the United States Green Building Council’s Leadership in Energy and Environmental Design (“LEED”)rating system (or other applicable certification standard).

ARTICLE 8

CONDITION OF PREMISES

Tenant hereby agrees that except as provided in the Tenant Work Letter attached hereto as Exhibit “D” and made a part hereof, the Premises shall be taken “as is”, “with all faults”, “without any representations or warranties”, and Tenant hereby agrees and warrants that it has investigated and inspected the condition of the Premises and the suitability of same for Tenant’s purposes, and Tenant does hereby waive and disclaim any objection to, cause of action based upon, or claim that its obligations hereunder should be reduced or limited because of the condition of the Premises or the Project or the suitability of same for Tenant’s purposes. Tenant acknowledges that neither Landlord nor any agent nor any employee of Landlord has made any representations or warranty with respect to the Premises or the Project or with respect to the

-10-

suitability of either for the conduct of Tenant’s business and Tenant expressly warrants and represents that Tenant has relied solely on its own investigation and inspection of the Premises and the Project in its decision to enter into this Lease and let the Premises in the above-described condition. Nothing contained herein is intended to, nor shall, obligate Landlord to implement sustainability practices for the Project or to seek certification under, or make modifications in order to obtain, a certification from LEED or any other comparable certification. The Premises shall be initially improved as provided in, and subject to, the Tenant Work Letter attached hereto as Exhibit “D” and made a part hereof. The existing leasehold improvements in the Premises as of the date of this Lease, together with the Improvements (as defined in the Tenant Work Letter) may be collectively referred to herein as the “Tenant Improvements.” The taking of possession of the Premises by Tenant shall conclusively establish that the Premises and the Project were at such time in satisfactory condition. Tenant hereby waives subsection 1 of Section 1932 and Sections 1941 and 1942 of the Civil Code of California or any successor provision of law.

ARTICLE 9

REPAIRS AND ALTERATIONS

(a) Landlord’s Obligations. Landlord shall maintain the structural portions of the Project, including the foundation, floor/ceiling slabs, roof, curtain wall, exterior glass, columns, beams, shafts, stairs, stairwells, elevator cabs and common areas, and shall also maintain and repair the basic mechanical, electrical, life safety, plumbing, sprinkler systems and heating, ventilating and air-conditioning systems (provided, however, that Landlord’s obligation with respect to any such systems shall be to repair and maintain those portions of the systems located in the core of the Project or in other areas outside of the Premises, but Tenant shall be responsible to repair and maintain any distribution of such systems throughout the Premises).

(b) Tenant’s Obligations. Except as expressly provided as Landlord’s obligation in this Article 9, Tenant shall keep the Premises in good condition and repair and in compliance with Landlord’s sustainability practices including, without limitation, compliance with any LEED rating system (or other certification standard) applicable to the Project. All damage or injury to the Premises or the Project resulting from the act or negligence of Tenant, its employees, agents or visitors, guests, invitees or licensees or by the use of the Premises, shall be promptly repaired by Tenant at its sole cost and expense, to the satisfaction of Landlord; provided, however, that for damage to the Project as a result of casualty or for any repairs that may impact the mechanical, electrical, plumbing, heating, ventilation or air-conditioning systems of the Project, Landlord shall have the right (but not the obligation) to select the contractor and oversee all such repairs. Landlord may make any repairs which are not promptly made by Tenant after Tenant’s receipt of written notice and the reasonable opportunity of Tenant to make said repair within five (5) business days from receipt of said written notice, and charge Tenant for the cost thereof, which cost shall be paid by Tenant within five (5) days from invoice from Landlord. Tenant shall be responsible for the design and function of all non-standard improvements of the Premises, whether or not installed by Landlord at Tenant’s request. Tenant waives all rights to make repairs at the expense of Landlord, or to deduct the cost thereof from the rent.

(c) Alterations. Tenant shall make no alterations, installations, changes or additions in or to the Premises or the Project (collectively, “Alterations”) without Landlord’s prior written consent. Without limitation as to other grounds for Landlord withholding its consent to any proposed Alteration, Landlord may withhold its consent to a proposed Alteration if Landlord determines that such Alteration is not compatible with any existing or planned future certification of the Project under the LEED rating system (or other applicable certification standard). Any Alterations approved by Landlord must be performed in accordance with the terms hereof, using only contractors or mechanics approved by Landlord in writing and upon the approval by Landlord in writing of fully detailed and dimensioned plans and specifications pertaining to the Alterations in question, to be prepared and submitted by Tenant at its sole cost and expense. Tenant shall at its sole cost and expense obtain all necessary approvals and permits pertaining to any Alterations approved by Landlord. Tenant shall cause all Alterations to be performed in a good and workmanlike manner, in conformance with all applicable federal, state, county and municipal laws, rules and regulations, pursuant to a valid building permit, and in conformance with Landlord’s construction rules and regulations. If Landlord, in approving any Alterations, specifies a commencement date therefor, Tenant shall not commence any work with respect to such Alterations prior to such date. Tenant hereby agrees to indemnify, defend, and hold Landlord free and harmless from all liens and claims of lien, and all other liability, claims

-11-

and demands arising out of any work done or material supplied to the Premises by or at the request of Tenant in connection with any Alterations. Tenant shall be entitled to install, as an initial Tenant Improvement or as an Alteration, dedicated heating, ventilation and air conditioning units (“Supplemental Units”) within the Premises at Tenant’s sole cost and expense. The plans and specifications for any Supplemental Units shall, as indicated in this Article 9 above and the Tenant Work Letter (as applicable), be subject to Landlord’s reasonable approval. If Tenant elects to install Supplemental Units within the Premises, Tenant shall be responsible for the cost of electricity supplied to such units pursuant to the procedure described in Section 11(a) below. Tenant shall be solely responsible for maintenance and repair of the Supplemental Units and such units shall be considered to be a fixture within the Premises and shall remain upon the Premises upon the expiration or earlier termination of the Lease Term.

(d) Insurance; Liens. Prior to the commencement of any Alterations, Tenant shall provide Landlord with evidence that Tenant carries “Builder’s All Risk” insurance in an amount approved by Landlord covering the construction of such Alterations, and such other insurance as Landlord may reasonably require, it being understood that all such Alterations shall be insured by Tenant pursuant to Article 14 of this Lease immediately upon completion thereof. In addition, Landlord may, in its discretion, require Tenant to obtain a bond or some alternate form of security satisfactory to Landlord in an amount sufficient to ensure the lien free completion of such Alterations.

(e) Costs and Fees; Removal. If permitted Alterations are made, they shall be made at Tenant’s sole cost and expense and shall be and become the property of Landlord, except that Landlord may, by written notice to Tenant given at the time of Landlord’s consent to any Improvements or Alterations, require Tenant at Tenant’s expense to remove such Improvements or other Alterations from the Premises upon expiration or earlier termination of this Lease, and to repair any damage to the Premises and the Project caused by such removal. Notwithstanding any other provision of this Lease, Tenant shall not, however, be required to remove any of the existing (as of the date of this Lease) Tenant Improvements in the Premises or any Tenant Improvement shown on the Final Space Plan (as such term is defined in the Tenant Work Letter attached hereto as Exhibit “D” and incorporated herein by this reference). Any and all costs attributable to or related to the applicable building codes of the city in which the Project is located (or any other authority having jurisdiction over the Project) arising from Tenant’s plans, specifications, improvements, Alterations or otherwise shall be paid by Tenant at its sole cost and expense. With regard to repairs, Alterations or any other work arising from or related to this Article 9, Landlord shall be entitled to receive an administrative/coordination fee (which fee shall vary depending upon whether or not Tenant orders the work directly from Landlord) sufficient to compensate Landlord for all overhead, general conditions, fees and other costs and expenses arising from Landlord’s involvement with such work. The construction of initial improvements to the Premises shall be governed by the terms of the Tenant Work Letter and not the terms of this Article 9, except as expressly provided in the first sentence of this Section 9(e).

ARTICLE 10

LIENS

Tenant shall keep the Premises and the Project free from any mechanics’ liens, vendors liens or any other liens arising out of any work performed, materials furnished or obligations incurred by Tenant, and Tenant agrees to defend, indemnify and hold Landlord harmless from and against any such lien or claim or action thereon, together with costs of suit and reasonable attorneys’ fees and costs incurred by Landlord in connection with any such claim or action. Before commencing any work of alteration, addition or improvement to the Premises, Tenant shall give Landlord at least ten (10) business days’ written notice of the proposed commencement of such work (to afford Landlord an opportunity to post appropriate notices of non-responsibility). In the event that there shall be recorded against the Premises or the Project or the property of which the Premises is a part any claim or lien arising out of any such work performed, materials furnished or obligations incurred by Tenant and such claim or lien shall not be removed or discharged within ten (10) days of filing, Landlord shall have the right but not the obligation to pay and discharge said lien without regard to whether such lien shall be lawful or correct (in which case Tenant shall reimburse Landlord for any such payment made by Landlord within ten (10) days following written demand), or to require that Tenant promptly deposit with Landlord in cash, lawful money of the United States, one hundred fifty percent (150%) of the amount of such claim, which sum may be retained by Landlord until such claim shall have been removed of record or until judgment shall have been rendered on such claim and such judgment

-12-

shall have become final, at which time Landlord shall have the right to apply such deposit in discharge of the judgment on said claim and any costs, including attorneys’ fees and costs incurred by Landlord, and shall remit the balance thereof to Tenant.

ARTICLE 11

PROJECT SERVICES

(a) Basic Services. Landlord agrees to furnish to the Premises, at a cost to be included in Operating Costs, from 7:00 a.m. to 6:00 p.m. Mondays through Fridays and 9:00 a.m. to 1:00 p.m. on Saturdays, excepting local and national holidays, air conditioning and heat all in such reasonable quantities as in the judgment of Landlord is reasonably necessary for the comfortable occupancy of the Premises. In addition, Landlord shall provide electric current for normal lighting and normal office machines, elevator service and water on the same floor as the Premises for lavatory and drinking purposes in such reasonable quantities as in the judgment of Landlord is reasonably necessary for general office use and in compliance with applicable codes. To the extent reasonably determined by Landlord to be practicable, all such electricity (including, without limitation, electricity in order to power the heating, ventilation and air conditioning system serving the Premises), shall be separately metered or submetered at Tenant’s expense and Tenant shall make payment directly to the entity providing such electricity to the Premises if such separate meters are installed. If, however, separate meters are not installed and the Premises are submetered or are jointly metered, then Landlord shall determine and Tenant shall pay the amount reasonably determined by Landlord to be Tenant’s equitable share of the monthly charge for such electricity, as Additional Rent. Tenant shall cooperate with Landlord’s efforts to cause the utilities for the Project to comply with Landlord’s sustainability practices and any LEED rating (or other applicable certification standard) applicable to the Project. Such efforts may include, without limitation, the use of energy efficient bulbs in task lighting, energy efficient lighting controls and measures to avoid over-lighting interior spaces. Janitorial and maintenance services shall be furnished five (5) days per week, excepting local and national holidays. Tenant shall comply with all rules and regulations which Landlord may establish for the proper functioning and protection of the common area air conditioning, heating, elevator, electrical, intrabuilding cabling and wiring and plumbing systems. Landlord shall not be liable for, and there shall be no rent abatement as a result of, any stoppage, reduction or interruption of any such services caused by governmental rules, regulations or ordinances, riot, strike, labor disputes, breakdowns, accidents, necessary repairs or other cause. Except as specifically provided in this Article 11, Tenant agrees to pay for all utilities and other services utilized by Tenant and any additional building services furnished to Tenant which are not uniformly furnished to all tenants of the Project, at the rate generally charged by Landlord to tenants of the Project for such utilities or services.

(b) Excess Usage. Tenant will not, without the prior written consent of Landlord, use any apparatus or device in the Premises which will in any way increase the amount of electricity or water usually furnished or supplied for use of the Premises as general office space; nor connect any apparatus, machine or device with water pipes or electric current (except through existing electrical outlets in the Premises), for the purpose of using electric current or water. Tenant shall promptly respond to all reasonable informational requests made by Landlord from time to time regarding Landlord’s reporting requirements under the LEED rating system (or other applicable certification standard) including, without limitation, informational requests regarding Tenant’s utility usage.

(c) Additional Electrical Service. If Tenant shall require electric current in excess of that which Landlord is obligated to furnish under Section 11(a) above, Tenant shall first obtain the written consent of Landlord, which Landlord may refuse in its sole and absolute discretion.

(d) HVAC Balance. If any lights, machines or equipment (including but not limited to computers and computer systems and appurtenances) are used by Tenant in the Premises which materially affect the temperature otherwise maintained by the air conditioning system, or generate substantially more heat in the Premises than would be generated by the building standard lights and usual office equipment, Landlord shall have the right to install any machinery and equipment which Landlord reasonably deems necessary to restore temperature balance, including but not limited to modifications to the standard air conditioning equipment, and the cost thereof, including the cost of installation and any additional cost of operation and maintenance occasioned thereby, shall be paid by Tenant to Landlord upon demand by Landlord.

-13-

(e) Telecommunications. Upon request from Tenant from time to time, Landlord will provide Tenant with a listing of telecommunications and media service providers serving the Project, and Tenant shall have the right to contract directly with the providers of its choice. If Tenant wishes to contract with or obtain service from any provider which does not currently serve the Project or wishes to obtain from an existing carrier services which will require the installation of additional equipment, such provider must, prior to providing service, enter into a written agreement with Landlord setting forth the terms and conditions of the access to be granted to such provider. In considering the installation of any new or additional telecommunications cabling or equipment at the Project, Landlord will consider all relevant factors in a reasonable and non-discriminatory manner, including, without limitation, the existing availability of services at the Project, the impact of the proposed installations upon the Project and its operations and the available space and capacity for the proposed installations. Landlord may also consider whether the proposed service may result in interference with or interruption of other services at the Project or the business operations of other tenants or occupants of the Project. In no event shall Landlord be obligated to incur any costs or liabilities in connection with the installation or delivery of telecommunication services or facilities at the Project. All such installations shall be subject to Landlord’s prior approval and shall be performed in accordance with the terms of Article 9. If Landlord approves the proposed installations in accordance with the foregoing, Landlord will deliver its standard form agreement upon request and will use commercially reasonable efforts to promptly enter into an agreement on reasonable and non-discriminatory terms with a qualified, licensed and reputable carrier confirming the terms of installation and operation of telecommunications equipment consistent with the foregoing. Notwithstanding the foregoing, Landlord acknowledges that Tenant will have the right to use Cox Cable as its telecommunications provider for the Premises and Landlord will reasonably cooperate with Tenant and Cox Cable to grant to Cox Cable access to the Premises to provide such services.

(f) After-Hours Use. If Tenant requires heating, ventilation and/or air conditioning during times other than the times provided in Section 11(a) above, Tenant shall give Landlord such advance notice as Landlord shall reasonably require and shall pay Landlord’s standard charge for such after-hours use, which charge shall be an amount equal to Landlord’s reasonable estimate of Landlord’s actual cost to provide such after-hours heating, ventilation and/or air conditioning services. Tenant shall have after-hours access to the Project and will be provided with access key cards for such after-hours access in an amount reasonably required by Tenant in accordance with Section 26(f) of the Rules and Regulations.

If Tenant shall not be personally present to open and permit an entry into the Premises at any time when such an entry by Landlord is necessary or permitted hereunder, Landlord may enter by means of a master key, or may forcibly enter in the case of an emergency, in each event without liability to Tenant and without affecting this Lease.

ARTICLE 13

INDEMNITY; EXEMPTION OF LANDLORD FROM LIABILITY

(a) Indemnity. Tenant shall indemnify, defend and hold Landlord, Arden Realty, Inc., their subsidiaries, partners, parental or other affiliates and their respective members, shareholders, officers, directors, employees and contractors (collectively, “Landlord Parties”) harmless from any and all claims arising from Tenant’s use of the Premises or the Project or from the conduct of its business or from any activity, work or thing which may be permitted or suffered by Tenant in or about the Premises or the Project and shall further indemnify, defend and hold Landlord and the Landlord Parties harmless from and against any and all claims arising from any breach or default in the performance of any obligation on Tenant’s part to be performed under this Lease or arising from any negligence or willful misconduct of Tenant or any of its agents, contractors, employees or invitees, patrons, customers or members in or about the Project and from any and all costs, attorneys’ fees and costs, expenses and liabilities incurred in the defense of any claim or any action or proceeding brought thereon, including negotiations in connection therewith.

(b) Exemption of Landlord from Liability. Landlord and the Landlord Parties shall not be liable for injury to Tenant’s business, or loss of income therefrom, however occurring (including, without limitation, from any failure or interruption of services or utilities or as a result of Landlord’s negligence), or, except in connection with damage or injury resulting from the gross negligence or willful misconduct of Landlord or the Landlord Parties, for damage that may be sustained by the person, goods, wares, merchandise or property of Tenant, its employees, invitees, customers, agents, or contractors, or any other person in, on or about the Premises directly or indirectly caused by or resulting from any cause whatsoever, including, but not limited to, fire, steam, electricity, gas, water, or rain which may leak or flow from or into any part of the Premises, or from the breakage, leakage, obstruction or other defects of the pipes, sprinklers, wires, appliances, plumbing, air conditioning, light fixtures, or mechanical or electrical systems, or from intrabuilding cabling or wiring, whether such damage or injury results from conditions arising upon the Premises or upon other portions of the Project or from other sources or places and regardless of whether the cause of such damage or injury or the means of repairing the same is inaccessible to Tenant. Landlord and the Landlord Parties shall not be liable to Tenant for any damages arising from any willful or negligent action or inaction of any other tenant of the Project.

(c) Security. Tenant acknowledges that Landlord’s election whether or not to provide any type of mechanical surveillance or security personnel whatsoever in the Project is solely within Landlord’s discretion; Landlord and the Landlord Parties shall have no duty or liability in connection with the provision, or lack, of such services, and Tenant hereby agrees to hold Landlord and the Landlord Parties harmless with regard to any such potential claim. Landlord and the Landlord Parties shall not be liable for losses due to theft, vandalism, or like causes. Tenant shall defend, indemnify, and hold Landlord and the Landlord Parties harmless from and against any such claims made by any employee, licensee, invitee, contractor, agent or other person whose presence in, on or about the Premises or the Project is attendant to the business of Tenant.

ARTICLE 14

INSURANCE

(a) Tenant’s Insurance. Tenant, shall at all times during the Term of this Lease, and at its own cost and expense, procure and continue in force the following insurance coverage: (i) Commercial General Liability Insurance, written on an occurrence basis, with a combined single limit for bodily injury and property damages of not less than Two Million Dollars

($2,000,000) per occurrence and Three Million Dollars ($3,000,000) in the annual aggregate, including products liability coverage if applicable, owners and contractors protective coverage, blanket contractual coverage including both oral and written contracts, and personal injury coverage, covering the insuring provisions of this Lease and the performance of Tenant of the indemnity and exemption of Landlord from liability agreements set forth in Article 13 hereof; (ii) a policy of standard fire, extended coverage and special extended coverage insurance (all risks), including a vandalism and malicious mischief endorsement, sprinkler leakage coverage and earthquake sprinkler leakage where sprinklers are provided in an amount equal to the full replacement value new without deduction for depreciation of all (A) Tenant Improvements, Alterations, fixtures and other improvements in the Premises, including but not limited to all mechanical, plumbing, heating, ventilating, air conditioning, electrical, telecommunication and other equipment, systems and facilities, and (B) trade fixtures, furniture, equipment and other personal property installed by or at the expense of Tenant; (iii) Worker’s Compensation coverage as required by law; and (iv) business interruption, loss of income and extra expense insurance covering any failure or interruption of Tenant’s business equipment (including, without limitation, telecommunications equipment) and covering all other perils, failures or interruptions sufficient to cover a period of interruption of not less than twelve (12) months. Tenant shall carry and maintain during the entire Term (including any option periods, if applicable), at Tenant’s sole cost and expense, increased amounts of the insurance required to be carried by Tenant pursuant to this Article 14 and such other reasonable types of insurance coverage and in such reasonable amounts covering the Premises and Tenant’s operations therein, as may be reasonably required by Landlord.

(b) Form of Policies. The aforementioned minimum limits of policies and Tenant’s procurement and maintenance thereof shall in no event limit the liability of Tenant hereunder. The Commercial General Liability Insurance policy shall name Landlord, the Landlord Parties, Landlord’s property manager, Landlord’s lender(s) and such other persons or firms as Landlord specifies from time to time, as additional insureds with an appropriate endorsement to the policy(s). All such insurance policies carried by Tenant shall be with companies having a rating of not less than A-VIII in Best’s Insurance Guide. Tenant shall furnish to Landlord, from the insurance companies, or cause the insurance companies to furnish, certificates of coverage. The deductible under each such policy shall be reasonably acceptable to Landlord. No such policy shall be cancelable or subject to reduction of coverage or other modification or cancellation except after thirty (30) days prior written notice to Landlord by the insurer. All such policies shall be endorsed to agree that Tenant’s policy is primary and that any insurance carried by Landlord is excess and not contributing with any Tenant insurance requirement hereunder. Tenant shall, at least twenty (20) days prior to the expiration of such policies, furnish Landlord with renewals or binders. Tenant agrees that if Tenant does not take out and maintain such insurance or furnish Landlord with renewals or binders in a timely manner, Landlord may (but shall not be required to) procure said insurance on Tenant’s behalf and charge Tenant the cost thereof, which amount shall be payable by Tenant upon demand with interest (at the rate set forth in Section 20(e) below) from the date such sums are expended. Tenant shall have the right to provide such insurance coverage pursuant to blanket policies obtained by Tenant, provided such blanket policies expressly afford coverage to the Premises and to Tenant as required by this Lease.

(c) Landlord’s Insurance. Landlord may, as a cost to be included in Operating Costs, procure and maintain at all times during the Term of this Lease, a policy or policies of insurance covering loss or damage to the Project in the amount of the full replacement cost without deduction for depreciation thereof, providing protection against all perils included within the classification of fire and extended coverage, vandalism coverage and malicious mischief, sprinkler leakage, water damage, and special extended coverage on the building. Additionally, Landlord may carry: (i) Bodily Injury and Property Damage Liability Insurance and/or Excess Liability Coverage Insurance; and (ii) Earthquake and/or Flood Damage Insurance; and (iii) Rental Income Insurance; and (iv) any other forms of insurance Landlord may deem appropriate or any lender may require. The costs of all insurance carried by Landlord shall be included in Operating Costs.

(d) Waiver of Subrogation. Landlord and Tenant each agree to require their respective insurers issuing the insurance described in Sections 14(a)(ii), 14(a)(iv) and the first sentence of Section 14(c), to waive any rights of subrogation that such companies may have against the other party. Tenant hereby waives any right that Tenant may have against Landlord

-16-

and Landlord hereby waives any right that Landlord may have against Tenant as a result of any loss or damage to the extent such loss or damage is insurable under such policies.

(e) Compliance with Insurance Requirements. Tenant agrees that it will not, at any time, during the Term of this Lease, carry any stock of goods or do anything in or about the Premises that will in any way tend to increase the insurance rates upon the Project. Tenant agrees to pay Landlord forthwith upon demand the amount of any increase in premiums for insurance that may be carried during the Term of this Lease, or the amount of insurance to be carried by Landlord on the Project resulting from the foregoing, or from Tenant doing any act in or about the Premises that does so increase the insurance rates, whether or not Landlord shall have consented to such act on the part of Tenant. If Tenant installs upon the Premises any electrical equipment which causes an overload of electrical lines of the Premises, Tenant shall at its own cost and expense, in accordance with all other Lease provisions (specifically including, but not limited to, the provisions of Article 9, 10 and 11 hereof), make whatever changes are necessary to comply with requirements of the insurance underwriters and any governmental authority having jurisdiction thereover, but nothing herein contained shall be deemed to constitute Landlord’s consent to such overloading. Tenant shall, at its own expense, comply with all insurance requirements applicable to the Premises including, without limitation, the installation of fire extinguishers or an automatic dry chemical extinguishing system.

ARTICLE 15

ASSIGNMENT AND SUBLETTING

Tenant shall have no power to, either voluntarily, involuntarily, by operation of law or otherwise, sell, assign, transfer or hypothecate this Lease, or sublet the Premises or any part thereof, or permit the Premises or any part thereof to be used or occupied by anyone other than Tenant or Tenant’s employees, officers, directors, and agents without the prior written consent of Landlord, which consent shall not be unreasonably withheld. Tenant may transfer its interest pursuant to this Lease only upon the following express conditions, which conditions are agreed by Landlord and Tenant to be reasonable:

(a) That the proposed Transferee (as hereafter defined) shall be subject to the prior written consent of Landlord, which consent will not be unreasonably withheld but, without limiting the generality of the foregoing, it shall be reasonable for Landlord to deny such consent if:

(i) The use to be made of the Premises by the proposed Transferee is (A) not generally consistent with the character and nature of all other tenancies in the Project, or (B) a use which conflicts with any so-called “exclusive” then in favor of another tenant of the Project or any other buildings which are in the same complex as the Project, or (C) a use that is not compatible with the existing certification or a planned future certification of the Project under the LEED rating system (or other applicable certification standard), or (D) a use which would be prohibited by any other portion of this Lease (including but not limited to any Rules and Regulations then in effect);

(ii) The financial responsibility of the proposed Transferee is not reasonably satisfactory to Landlord;

(iii) The proposed Transferee is either a governmental agency or instrumentality thereof; or

(iv) 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 (A) occupies space in the Project at the time of the request for consent, or (B) is negotiating with Landlord or has negotiated with Landlord during the six (6) month period immediately preceding the date of the proposed Transfer, to lease space in the Project.

(b) Upon Tenant’s submission of a request for Landlord’s consent to any such Transfer, Tenant shall pay to Landlord Landlord’s then standard processing fee and reasonable attorneys’ fees and costs incurred in connection with the proposed Transfer, which the parties hereby stipulate to be $1,000.00, unless Landlord provides to Tenant evidence that Landlord has incurred greater costs in connection with the proposed Transfer;

-17-

(c) That the proposed Transferee shall execute an agreement pursuant to which it shall agree to perform faithfully and be bound by all of the terms, covenants, conditions, provisions and agreements of this Lease applicable to that portion of the Premises so transferred; and

(d) That an executed duplicate original of said assignment and assumption agreement or other Transfer on a form reasonably approved by Landlord, shall be delivered to Landlord within five (5) days after the execution thereof, and that such Transfer shall not be binding upon Landlord until the delivery thereof to Landlord and the execution and delivery of Landlord’s consent thereto. It shall be a condition to Landlord’s consent to any subleasing, assignment or other transfer of part or all of Tenant’s interest in the Premises (“Transfer”) that (i) upon Landlord’s consent to any Transfer, Tenant shall pay and continue to pay Landlord fifty percent (50%) of any “Transfer Premium” (defined below), received by Tenant from the transferee; (ii) any sublessee of part or all of Tenant’s interest in the Premises shall agree that in the event Landlord gives such sublessee notice that Tenant is in default under this Lease, such sublessee shall thereafter make all sublease or other payments directly to Landlord, which will be received by Landlord without any liability whether to honor the sublease or otherwise (except to credit such payments against sums due under this Lease), and any sublessee shall agree to attorn to Landlord or its successors and assigns at their request should this Lease be terminated for any reason, except that in no event shall Landlord or its successors or assigns be obligated to accept such attornment; (iii) any such Transfer and consent shall be effected on forms supplied by Landlord and/or its legal counsel; (iv) Landlord may require that Tenant not then be in default beyond any applicable cure period hereunder in any respect; and (v) Tenant or the proposed subtenant or assignee (collectively, “Transferee”) shall agree to pay Landlord, upon demand, as Additional Rent, a sum equal to the additional costs, if any, incurred by Landlord for maintenance and repair as a result of any change in the nature of occupancy caused by such subletting or assignment. “Transfer Premium” shall mean all rent, Additional Rent or other consideration payable by a Transferee in connection with a Transfer in excess of the Basic Rental and Direct Costs payable by Tenant under this Lease during the term of the Transfer and if such Transfer is for less than all of the Premises, the Transfer Premium shall be calculated on a rentable square foot basis. The calculation of “Transfer Premium” shall also include, but not be limited to, key money, bonus money or other cash consideration paid by a Transferee to Tenant in connection with such Transfer, and any payment in excess of fair market value for services rendered by Tenant to the Transferee and any payment in excess of fair market value for assets, fixtures, inventory, equipment, or furniture transferred by Tenant to the Transferee in connection with such Transfer. Any Transfer of this Lease which is not in compliance with the provisions of this Article 15 shall be voidable by written notice from Landlord and shall, at the option of Landlord, terminate this Lease. In no event shall the consent by Landlord to any Transfer be construed as relieving Tenant or any Transferee from obtaining the express written consent of Landlord to any further Transfer, or as releasing Tenant from any liability or obligation hereunder whether or not then accrued and Tenant shall continue to be fully liable therefor. No collection or acceptance of rent by Landlord from any person other than Tenant shall be deemed a waiver of any provision of this Article 15 or the acceptance of any Transferee hereunder, or a release of Tenant (or of any Transferee of Tenant). Notwithstanding anything to the contrary in this Lease, if Tenant or any proposed Transferee claims that Landlord has unreasonably withheld or delayed its consent under this Article 15 or otherwise has breached or acted unreasonably under this Article 15, their sole remedies shall be a declaratory judgment and an injunction for the relief sought without any monetary damages, 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.

Notwithstanding anything to the contrary contained in this Article 15, an assignment or subletting of all or a portion of the Premises to an affiliate (“Affiliate”) of Tenant (an entity which is controlled by, controls, or is under common control with, Tenant or that acquires all or substantially all of Tenant’s assets or business), shall not be deemed a Transfer under this Article 15, 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 assignment or sublease or such affiliate, and further provided that (i) such assignment or sublease is not a subterfuge by Tenant to avoid its obligations under this Lease, and (ii) Landlord confirms that such assignee or subtenant does not violate Landlord’s “know your customer” requirements. An assignee of Tenant’s entire interest in this Lease pursuant to the immediately preceding sentence may be referred to herein as an “Affiliated Assignee.” “Control,” as used in

-18-

this Article 15, shall mean the ownership, directly or indirectly, of greater than fifty percent (50%) of the voting securities of, or possession of the right to vote, in the ordinary direction of its affairs, of greater than fifty percent (50%) of the voting interest in, an entity.

ARTICLE 16

DAMAGE OR DESTRUCTION

If the Project is damaged by fire or other insured casualty and the insurance proceeds have been made available therefor by the holder or holders of any mortgages or deeds of trust covering the Premises or the Project, the damage shall be repaired by Landlord to the extent such insurance proceeds are available therefor and provided such repairs can, in Landlord’s sole opinion, be completed within one hundred eighty (180) days after the necessity for repairs as a result of such damage becomes known to Landlord, without the payment of overtime or other premiums, and until such repairs are completed rent shall be abated in proportion to the part of the Premises which is unusable by Tenant in the conduct of its business (but there shall be no abatement of rent by reason of any portion of the Premises being unusable for a period equal to one (1) day or less). However, if the damage is due to the fault or neglect of Tenant, its employees, agents, contractors, guests, invitees and the like, there shall be no abatement of rent, unless and to the extent Landlord receives rental income insurance proceeds. Within sixty (60) days after the date Landlord learns of the necessity for repairs as a result of damage, Landlord shall notify Tenant (“Damage Repair Estimate”) of Landlord’s estimated assessment of the period of time in which the repairs will be completed. Upon the occurrence of any damage to the Premises, Tenant shall assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under Section 14(a)(ii)(A) above; provided, however, that if the cost of repair of improvements within the Premises by Landlord exceeds the amount of insurance proceeds received by Landlord from Tenant’s insurance carrier, as so assigned by Tenant, such excess costs shall be paid by Tenant to Landlord prior to Landlord’s repair of such damage. If the Damage Repair Estimate indicates that repairs cannot, in Landlord’s opinion, be completed within one hundred eighty (180) days after the necessity for repairs as a result of such damage becomes known to Landlord without the payment of overtime or other premiums, Landlord may, at its option, either (i) make such repairs in a reasonable time and in such event this Lease shall continue in effect and the rent shall be abated, if at all, in the manner provided in this Article 16, or (ii) elect not to effect such repairs and instead terminate this Lease, by notifying Tenant in writing of such termination within sixty (60) days after Landlord learns of the necessity for repairs as a result of damage, such notice to include a termination date giving Tenant sixty (60) days to vacate the Premises. In addition, Landlord may elect to terminate this Lease if the Project shall be damaged by fire or other casualty or cause, whether or not the Premises are affected, if the damage is not fully covered, except for deductible amounts, by Landlord’s insurance policies. However, if Landlord does not elect to terminate this Lease pursuant to Landlord’s termination right as provided above, and if the Damage Repair Estimate indicates that repairs cannot be completed within one hundred eighty (180) days after being commenced and if such damage is not the result of the negligence or willful misconduct of Tenant or Tenant’s employees, licensees, invitees or agents, Tenant may elect, not later than thirty (30) days after Tenant’s receipt of the Damage Repair Estimate, to terminate this Lease by written notice to Landlord effective as of the date specified in Tenant’s notice. Finally, if the Premises or the Project is damaged to any substantial extent during the last twelve (12) months of the Term, then notwithstanding anything contained in this Article 16 to the contrary, Landlord shall have the option to terminate this Lease by giving written notice to Tenant of the exercise of such option within sixty (60) days after Landlord learns of the necessity for repairs as the result of such damage. In the event that the Premises or the Project is destroyed or damaged to any substantial extent during the last twelve (12) months of the Lease Term and if such damage shall take longer than sixty (60) days to repair and if such damage is not the result of the negligence or willful misconduct of Tenant or Tenant’s employees, licensees, invitees or agents, then notwithstanding anything in this Article 16 to the contrary, Tenant shall have the option to terminate this Lease by written notice to Landlord of the exercise of such option within sixty (60) days after Tenant learns of the necessity for repairs as the result of such damage. A total destruction of the Project shall automatically terminate this Lease. Except as provided in this Article 16, there shall be no abatement of rent and no liability of Landlord by reason of any injury to or interference with Tenant’s business or property arising from such damage or destruction or the making of any repairs, alterations or improvements in or to any portion of the Project or the Premises or in or to fixtures, appurtenances and equipment therein. Tenant understands that Landlord will not carry insurance of any kind on Tenant’s furniture, furnishings, trade fixtures or equipment, and that

-19-

Landlord shall not be obligated to repair any damage thereto or replace the same. Tenant acknowledges that Tenant shall have no right to any proceeds of insurance carried by Landlord relating to property damage. With respect to any damage which Landlord is obligated to repair or elects to repair, Tenant, as a material inducement to Landlord entering into this Lease, irrevocably waives and releases its rights under the provisions of Sections 1932 and 1933 of the California Civil Code.

ARTICLE 17

SUBORDINATION

This Lease is subject to, and Tenant agrees to comply with, all matters of record affecting the Real Property. This Lease is also subject and subordinate to all ground or underlying leases, mortgages and deeds of trust which affect the Real Property, including all renewals, modifications, consolidations, replacements and extensions thereof; provided, however, if the lessor under any such lease or the holder or holders of any such mortgage or deed of trust shall advise Landlord that they desire or require this Lease to be prior and superior thereto, upon written request of Landlord to Tenant, Tenant agrees to promptly execute, acknowledge and deliver any and all documents or instruments which Landlord or such lessor, holder or holders deem necessary or desirable for purposes thereof. Landlord shall have the right to cause this Lease to be and become and remain subject and subordinate to any and all ground or underlying leases, mortgages or deeds of trust which may hereafter be executed covering the Premises, the Project or the property or any renewals, modifications, consolidations, replacements or extensions thereof, for the full amount of all advances made or to be made thereunder and without regard to the time or character of such advances, together with interest thereon and subject to all the terms and provisions thereof; provided, however, that Landlord obtains from the lender or other party in question a written undertaking in favor of Tenant to the effect that such lender or other party will not disturb Tenant’s right of possession under this Lease if Tenant is not then or thereafter in breach of any covenant or provision of this Lease. Tenant agrees, within ten (10) days after Landlord’s written request therefor, to execute, acknowledge and deliver upon request any and all documents or instruments requested by Landlord or necessary or proper to assure the subordination of this Lease to any such mortgages, deed of trust, or leasehold estates (hereinafter, an “SNDA”). Tenant agrees that in the event any proceedings are brought for the foreclosure of any mortgage or deed of trust or any deed in lieu thereof, to attorn to the purchaser or any successors thereto upon any such foreclosure sale or deed in lieu thereof as so requested to do so by such purchaser and to recognize such purchaser as the lessor under this Lease; Tenant shall, within five (5) days after request execute such further instruments or assurances as such purchaser may reasonably deem necessary to evidence or confirm such attornment. Tenant agrees to provide copies of any notices of Landlord’s default under this Lease to any mortgagee or deed of trust beneficiary whose address has been provided to Tenant and Tenant shall provide such mortgagee or deed of trust beneficiary a commercially reasonable time after receipt of such notice within which to cure any such default. Tenant waives the provisions of any current or future statute, rule or law which may give or purport to give Tenant any right or election to terminate or otherwise adversely affect this Lease and the obligations of the Tenant hereunder in the event of any foreclosure proceeding or sale.

ARTICLE 18

EMINENT DOMAIN

If the whole of the Premises or the Project or so much thereof as to render the balance unusable by Tenant shall be taken under power of eminent domain, or is sold, transferred or conveyed in lieu thereof, this Lease shall automatically terminate as of the date of such condemnation, or as of the date possession is taken by the condemning authority, at Landlord’s option. No award for any partial or entire taking shall be apportioned, and Tenant hereby assigns to Landlord any award which may be made in such taking or condemnation, together with any and all rights of Tenant now or hereafter arising in or to the same or any part thereof; provided, however, that nothing contained herein shall be deemed to give Landlord any interest in or to require Tenant to assign to Landlord any award made to Tenant for the taking of personal property and trade fixtures belonging to Tenant and removable by Tenant at the expiration of the Term hereof as provided hereunder or for the interruption of, or damage to, Tenant’s business. In the event of a partial taking described in this Article 18, or a sale, transfer or conveyance in lieu thereof, which does not result in a termination of this Lease, the rent shall be apportioned according to the ratio that the part of the Premises remaining useable by Tenant bears to the total

-20-

area 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.

ARTICLE 19

DEFAULT

Each of the following acts or omissions of Tenant or of any guarantor of Tenant’s performance hereunder, or occurrences, shall constitute an “Event of Default”:

(a) Failure or refusal to pay Basic Rental, Additional Rent or any other amount to be paid by Tenant to Landlord hereunder within three (3) calendar days after notice that the same is due or payable hereunder; said three (3) day period shall be in lieu of, and not in addition to, the notice requirements of Section 1161 of the California Code of Civil Procedure or any similar or successor law;

(b) Except as set forth in items (a) above and (c) through and including (g) below, failure to perform or observe any other covenant or condition of this Lease to be performed or observed within thirty (30) days following written notice to Tenant of such failure. Such thirty (30) day notice shall be in lieu of, and not in addition to, any required under Section 1161 of the California Code of Civil Procedure or any similar or successor law;

(c) Abandonment or vacating or failure to accept tender of possession of the Premises or any significant portion thereof unless Tenant is marketing the Premises for sublease;

(d) The taking in execution or by similar process or law (other than by eminent domain) of the estate hereby created;

(e) The filing by Tenant or any guarantor hereunder in any court pursuant to any statute of a petition in bankruptcy or insolvency or for reorganization or arrangement for the appointment of a receiver of all or a portion of Tenant’s property; the filing against Tenant or any guarantor hereunder of any such petition, or the commencement of a proceeding for the appointment of a trustee, receiver or liquidator for Tenant, or for any guarantor hereunder, or of any of the property of either, or a proceeding by any governmental authority for the dissolution or liquidation of Tenant or any guarantor hereunder, if such proceeding shall not be dismissed or trusteeship discontinued within thirty (30) days after commencement of such proceeding or the appointment of such trustee or receiver; or the making by Tenant or any guarantor hereunder of an assignment for the benefit of creditors. Tenant hereby stipulates to the lifting of the automatic stay in effect and relief from such stay for Landlord in the event Tenant files a petition under the United States Bankruptcy laws, for the purpose of Landlord pursuing its rights and remedies against Tenant and/or a guarantor of this Lease;

(f) Tenant’s failure to cause to be released any mechanics liens filed against the Premises or the Project within twenty (20) days after the date the same shall have been filed or recorded; or

All defaults by Tenant of any covenant or condition of this Lease shall be deemed by the parties hereto to be material.

ARTICLE 20

REMEDIES

(a) Upon the occurrence of an Event of Default under this Lease as provided in Article 19 hereof, Landlord may exercise all of its remedies as may be permitted by law, including but not limited to the remedy provided by Section 1951.4 of the California Civil Code, and including without limitation, terminating this Lease, reentering the Premises and removing all persons and property therefrom, which property may be stored by Landlord at a warehouse or elsewhere at the risk, expense and for the account of Tenant. If Landlord elects to terminate this Lease, Landlord shall be entitled to recover from Tenant the aggregate of all amounts permitted by law, including but not limited to (i) the worth at the time of award of the amount of any unpaid rent which had 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

-21-

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 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, tenant improvement expenses, brokerage commissions and advertising expenses incurred, expenses of remodeling the Premises or any portion thereof for a new tenant, whether for the same or a different use, and any special concessions made to obtain a new tenant; and (v) at Landlord’s election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by applicable law. The term “rent” as used in this Section 20(a) shall be deemed to be and to mean all sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or to others. As used in items (i) and (ii), above, the “worth at the time of award” shall be computed by allowing interest at the rate set forth in item (e), below, but in no case greater than the maximum amount of such interest permitted by law. As used in item (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%).

(b) Nothing in this Article 20 shall be deemed to affect Landlord’s right to indemnification for liability or liabilities arising prior to the termination of this Lease for personal injuries or property damage under the indemnification clause or clauses contained in this Lease.

(c) Notwithstanding anything to the contrary set forth herein, Landlord’s re-entry to perform acts of maintenance or preservation of or in connection with efforts to relet the Premises or any portion thereof, or the appointment of a receiver upon Landlord’s initiative to protect Landlord’s interest under this Lease shall not terminate Tenant’s right to possession of the Premises or any portion thereof and, until Landlord does elect to terminate this Lease, this Lease shall continue in full force and effect and Landlord may enforce all of Landlord’s rights and remedies hereunder including, without limitation, 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.

(d) All rights, powers and remedies of Landlord hereunder and under any other agreement now or hereafter in force between Landlord and Tenant shall be cumulative and not alternative and shall be in addition to all rights, powers and remedies given to Landlord by law, and the exercise of one or more rights or remedies shall not impair Landlord’s right to exercise any other right or remedy.

(e) Any amount due from Tenant to Landlord hereunder which is not paid when due shall bear interest at the lower of eighteen percent (18%) per annum or the maximum lawful rate of interest from the due date until paid, unless otherwise specifically provided herein, but the payment of such interest shall not excuse or cure any default by Tenant under this Lease. In addition to such interest: (i) if Basic Rental is not paid on or before the fifth (5^th) day of the calendar month for which the same is due, a late charge equal to five percent (5%) of the amount overdue or $100, whichever is greater, shall be immediately due and owing and shall accrue for each calendar month or part thereof until such rental, including the late charge, is paid in full, which late charge Tenant hereby agrees is a reasonable estimate of the damages Landlord shall suffer as a result of Tenant’s late payment and (ii) an additional charge of $25 shall be assessed for any check given to Landlord by or on behalf of Tenant which is not honored by the drawee thereof; which damages include Landlord’s additional administrative and other costs associated with such late payment and unsatisfied checks and the parties agree that it would be impracticable or extremely difficult to fix Landlord’s actual damage in such event. Such charges for interest and late payments and unsatisfied checks are separate and cumulative and are in addition to and shall not diminish or represent a substitute for any or all of Landlord’s rights or remedies under any other provision of this Lease.

-22-

(f) In the event of any default, breach or violation of Tenant’s rights under this Lease by Landlord, Tenant’s exclusive remedies shall be an action for specific performance or action for actual damages. Without limiting any other waiver by Tenant which may be contained in this Lease, Tenant hereby waives the benefit of any law granting it the right to perform Landlord’s obligation, or the right to terminate this Lease on account of any Landlord default.

ARTICLE 21

TRANSFER OF LANDLORD’S INTEREST

In the event of any transfer or termination of Landlord’s interest in the Premises or the Project by sale, assignment, transfer, foreclosure, deed-in-lieu of foreclosure or otherwise whether voluntary or involuntary, Landlord shall be automatically relieved of any and all obligations and liabilities on the part of Landlord from and after the date of such transfer or termination, including furthermore without limitation, the obligation of Landlord under Article 4 and California Civil Code 1950.7 above to return the cash security deposit and Letter of Credit, provided said cash security deposit and Letter of Credit are transferred to said transferee. Tenant agrees to attorn to the transferee upon any such transfer and to recognize such transferee as the lessor under this Lease and Tenant shall, within five (5) days after request, execute such further instruments or assurances as such transferee may reasonably deem necessary to evidence or confirm such attornment.

ARTICLE 22

BROKER

In connection with this Lease, Tenant warrants and represents that it has had dealings only with firm(s) set forth in Article 1.I. of the Basic Lease Provisions and that it knows of no other person or entity who is or might be entitled to a commission, finder’s fee or other like payment in connection herewith and does hereby indemnify and agree to hold Landlord, its agents, members, partners, representatives, officers, affiliates, shareholders, employees, successors and assigns harmless from and against any and all loss, liability and expenses that Landlord may incur should such warranty and representation prove incorrect, inaccurate or false.

ARTICLE 23

PARKING

Tenant shall be entitled to use, commencing on the Commencement Date, the number of unreserved parking passes set forth in Article 1.J. of the Basic Lease Provisions, which parking passes shall pertain to the Project parking facility. Tenant shall not be required to pay to Landlord any fee for such unreserved parking passes during the initial Term of this Lease; however, Tenant shall be responsible for the full amount of any taxes imposed by any governmental authority in connection with the use of such parking passes by Tenant or the use of the parking facility by Tenant. 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 are located, including any sticker or other identification system established by Landlord, Tenant’s cooperation in seeing that Tenant’s employees and visitors also comply with such rules and regulations, and Tenant not being in default under this Lease. Landlord specifically reserves the right to change the size, configuration, design, layout and all other aspects of the Project parking facility at any time and Tenant acknowledges and agrees that Landlord may, without incurring any liability to Tenant and without any abatement of rent under this Lease, from time to time, close-off or restrict access to the Project parking facility for purposes of permitting or facilitating any such construction, alteration or improvements. Landlord may, from time to time, relocate any reserved parking spaces (if any) used by Tenant to another location in the Project parking facility. Landlord may delegate its responsibilities hereunder to a parking operator or a lessee of the parking facility in which case such parking operator or lessee shall have all the rights of control attributed hereby to the Landlord. The parking passes used by Tenant pursuant to this Article 23 are provided to Tenant solely for use by Tenant’s own personnel and such passes may not be transferred, assigned, subleased or otherwise alienated by Tenant without Landlord’s prior approval.

-23-

ARTICLE 24

WAIVER

No waiver by Landlord of any provision of this Lease shall be deemed to be a waiver of any other provision hereof or of any subsequent breach by Tenant of the same or any other provision. No provision of this Lease may be waived by Landlord, except by an instrument in writing executed by Landlord. Landlord’s consent to or approval of any act by Tenant requiring Landlord’s consent or approval shall not be deemed to render unnecessary the obtaining of Landlord’s consent to or approval of any subsequent act of Tenant, whether or not similar to the act so consented to or approved. No act or thing done by Landlord or Landlord’s agents during the Term of this Lease shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept such surrender shall be valid unless in writing and signed by Landlord. 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. Any payment by Tenant or receipt by Landlord of an amount less than the total amount then due hereunder shall be deemed to be in partial payment only thereof and not a waiver of the balance due or an accord and satisfaction, notwithstanding any statement or endorsement to the contrary on any check or any other instrument delivered concurrently therewith or in reference thereto. Accordingly, Landlord may accept any such amount and negotiate any such check without prejudice to Landlord’s right to recover all balances due and owing and to pursue its other rights against Tenant under this Lease, regardless of whether Landlord makes any notation on such instrument of payment or otherwise notifies Tenant that such acceptance or negotiation is without prejudice to Landlord’s rights.

ARTICLE 25

ESTOPPEL CERTIFICATE

Tenant shall, at any time and from time to time, upon not less than ten (10) days’ prior written notice from Landlord, execute, acknowledge and deliver to Landlord a statement in writing certifying the following information, (but not limited to the following information in the event further information is requested by Landlord): (i) that this Lease is unmodified and in full force and effect (or, if modified, stating the nature of such modification and certifying that this Lease, as modified, is in full force and effect); (ii) the dates to which the rental and other charges are paid in advance, if any; (iii) the amount of Tenant’s cash security deposit and the Stated Amount of the Letter of Credit, if any; and (iv) acknowledging that there are not, to Tenant’s knowledge, any uncured defaults on the part of Landlord hereunder, and no events or conditions then in existence which, with the passage of time or notice or both, would constitute a default on the part of Landlord hereunder, or specifying such defaults, events or conditions, if any are claimed. It is expressly understood and agreed that any such statement may be relied upon by any prospective purchaser or encumbrancer of all or any portion of the Real Property.

ARTICLE 26

LIABILITY OF LANDLORD

Notwithstanding anything in this Lease to the contrary, any remedy of Tenant for the collection of a judgment (or other judicial process) requiring the payment of money by Landlord in the event of any default by Landlord hereunder or any claim, cause of action or obligation, contractual, statutory or otherwise by Tenant against Landlord or the Landlord Parties concerning, arising out of or relating to any matter relating to this Lease and all of the covenants and conditions or any obligations, contractual, statutory, or otherwise set forth herein, shall be limited solely and exclusively to an amount which is equal to the lesser of (i) the interest of Landlord in and to the Project, and (ii) the interest Landlord would have in the Project if the Project were encumbered by third party debt in an amount equal to eighty percent (80%) of the then current value of the Project. No other property or assets of Landlord or any Landlord Party shall be subject to levy, execution or other enforcement procedure for the satisfaction of Tenant’s remedies under or with respect to this Lease, Landlord’s obligations to Tenant, whether contractual, statutory or otherwise, the relationship of Landlord and Tenant hereunder, or Tenant’s use or occupancy of the Premises.

-24-

ARTICLE 27

INABILITY TO PERFORM

This Lease and the obligations of Tenant hereunder shall not be affected or impaired because Landlord is unable to fulfill any of its obligations hereunder or is delayed in doing so, if such inability or delay is caused by reason of any prevention, delay, stoppage due to strikes, lockouts, acts of God, terrorism, evacuation or any other cause previously, or at such time, beyond the reasonable control or anticipation of Landlord (collectively, a “Force Majeure”) and Landlord’s obligations under this Lease shall be forgiven and suspended by any such Force Majeure.

ARTICLE 28

HAZARDOUS WASTE

(a) Tenant shall not cause or permit any Hazardous Material (as defined in Section 28(d) below) to be brought, kept or used in or about the Project by Tenant, its agents, employees, contractors, or invitees. Tenant indemnifies Landlord and the Landlord Parties from and against any breach by Tenant of the obligations stated in the preceding sentence, and agrees to defend and hold Landlord and the Landlord Parties harmless from and against any and all claims, judgments, damages, penalties, fines, costs, liabilities, or losses (including, without limitation, diminution in value of the Project, damages for the loss or restriction or use of rentable or usable space or of any amenity of the Project, damages arising from any adverse impact or marketing of space in the Project, and sums paid in settlement of claims, attorneys’ fees and costs, consultant fees, and expert fees) which arise during or after the Term of this Lease as a result of such breach. This indemnification of Landlord and the Landlord Parties by Tenant includes, without limitation, costs incurred in connection with any investigation of site conditions or any cleanup, remedial, removal, or restoration work required by any federal, state, or local governmental agency or political subdivision because of Hazardous Material present in the soil or ground water on or under the Project. Without limiting the foregoing, if the presence of any Hazardous Material on the Project caused or permitted by Tenant results in any contamination of the Project, then subject to the provisions of Articles 9, 10 and 11 hereof, Tenant shall promptly take all actions at its sole expense as are necessary to return the Project to the condition existing prior to the introduction of any such Hazardous Material and the contractors to be used by Tenant for such work must be approved by Landlord, which approval shall not be unreasonably withheld so long as such actions would not potentially have any material adverse long-term or short-term effect on the Project and so long as such actions do not materially interfere with the use and enjoyment of the Project by the other tenants thereof; provided however, Landlord shall also have the right, by written notice to Tenant, to directly undertake any such mitigation efforts with regard to Hazardous Materials in or about the Project due to Tenant’s breach of its obligations pursuant to this Section 28(a), and to charge Tenant, as Additional Rent, for the costs thereof.

(b) Landlord and Tenant acknowledge that Landlord may become legally liable for the costs of complying with Laws (as defined in Section 28(e) below) relating to Hazardous Material which are not the responsibility of Landlord or the responsibility of Tenant, including the following: (i) Hazardous Material present in the soil or ground water on the Project of which Landlord has no knowledge as of the effective date of this Lease; (ii) a change in Laws which relate to Hazardous Material which make that Hazardous Material which is present on the Real Property as of the effective date of this Lease, whether known or unknown to Landlord, a violation of such new Laws; (iii) Hazardous Material that migrates, flows, percolates, diffuses, or in any way moves on to, or under, the Project after the effective date of this Lease; or Hazardous Material present on or under the Project as a result of any discharge, dumping or spilling (whether accidental or otherwise) on the Project by other lessees of the Project or their agents, employees, contractors, or invitees, or by others. Accordingly, Landlord and Tenant agree that the cost of complying with Laws relating to Hazardous Material on the Project for which Landlord is legally liable and which are paid or incurred by Landlord shall be an Operating Cost (and Tenant shall pay Tenant’s Proportionate Share thereof in accordance with Article 3) unless the cost of such compliance as between Landlord and Tenant, is made the responsibility of Tenant pursuant to Section 28(a) above. To the extent any such Operating Cost relating to Hazardous Material is subsequently recovered or reimbursed through insurance, or recovery from responsible third parties or other action, Tenant shall be entitled to a proportionate reimbursement to the extent it has paid its share of such Operating Cost to which such recovery or reimbursement relates.

-25-

(c) It shall not be unreasonable for Landlord to withhold its consent to any proposed Transfer if (i) the proposed transferee’s anticipated use of the Premises involves the generation, storage, use, treatment, or disposal of Hazardous Material; (ii) the proposed Transferee has been required by any prior landlord, lender, or governmental authority to take remedial action in connection with Hazardous Material contaminating a property if the contamination resulted from such Transferee’s actions or use of the property in question; or (iii) the proposed Transferee is subject to an enforcement order issued by any governmental authority in connection with the use, disposal, or storage of a Hazardous Material.

(d) As used herein, the term “Hazardous Material” means any hazardous or toxic substance, material, or waste which is or becomes regulated by any local governmental authority, the State of California or the United States Government. The term “Hazardous Material” includes, without limitation, any material or substance which is (i) defined as “Hazardous Waste,” “Extremely Hazardous Waste,” or “Restricted Hazardous Waste” under Sections 25115, 25117 or 25122.7, or listed pursuant to Section 25140, of the California Health and Safety Code, Division 20, Chapter 6.5 (Hazardous Waste Control Law), (ii) defined as a “Hazardous Substance” under Section 25316 of the California Health and Safety Code, Division 20, Chapter 6.8 (Carpenter-Presley-Tanner Hazardous Substance Account Act), (iii) defined as a “Hazardous Material,” “Hazardous Substance,” or “Hazardous Waste” under Section 25501 of the California Health and Safety Code, Division 20, Chapter 6.95 (Hazardous Materials Release Response Plans and Inventory), (iv) defined as a “Hazardous Substance” under Section 25281 of the California Health and Safety Code, Division 20, Chapter 6.7 (Underground Storage of Hazardous Substances), (v) petroleum, (vi) asbestos, (vii) listed under Article 9 or defined as Hazardous or extremely hazardous pursuant to Article 11 of Title 22 of the California Administrative Code, Division 4, Chapter 20, (viii) designated as a “Hazardous Substance” pursuant to Section 311 of the Federal Water Pollution Control Act (33 U.S.C. § 1317), (ix) defined as a “Hazardous Waste” pursuant to Section 1004 of the Federal Resource Conservation and Recovery Act, 42 U.S.C. § 6901 et seq.

-31-

to be used from the Premises, Tenant may so notify Landlord in writing (“Roof Equipment Notice”), which Roof Equipment Notice shall generally describe the specifications for the equipment desired by Tenant.

(E) Tenant shall use the Roof Equipment so as not to cause any interference to other tenants in the Project or with any other tenant’s Communication Equipment or the Project’s heating, ventilation and air condition system, and not to damage the Project or interfere with the normal operation of the Project.

(F) Landlord shall not have any obligations with respect to the Roof Equipment. Landlord makes no representation that (i) the Communications Equipment will be able to receive or transmit communication signals without interference or disturbance (whether or not by reason of the installation or use of similar equipment by others on the roof of the Project) or (ii) that the Supplemental Units will be able to adequately heat, ventilate or cool the Premises, and Tenant agrees that Landlord shall not be liable to Tenant therefor. Tenant shall not lease or otherwise make the Roof Equipment available to any third party and the Roof Equipment shall be only for Tenant’s use in connection with the conduct of Tenant’s business in the Premises.

-32-

Equipment and repair the Project within fifteen (15) days after the expiration or earlier termination of this Lease, Landlord may do so at Tenant’s expense. The provisions of this Section 30(aa)(H) shall survive the expiration or earlier termination of this Lease.

(I) The Roof Equipment shall be deemed to constitute a portion of the Premises for purposes of Articles 13 and 14 of this Lease.

(J) Upon request from Landlord, Tenant agrees to execute a license agreement with Landlord or Landlord’s rooftop management company regarding Tenant’s installation, use and operation of the Roof Equipment, which license agreement shall be in commercially reasonable form, shall not require any payments from Tenant and shall incorporate the terms and conditions of this Section 30(aa).

ARTICLE 31

SIGNAGE/DIRECTORY

Provided Tenant is not in default hereunder, as a charge to the Improvement Allowance (as defined in the Tenant Work Letter attached hereto as Exhibit “D” and made part hereof), Tenant shall have the right to (i) one (1) line in the lobby directory during the Term and (ii) Project-standard suite entry signage. In addition, provided Tenant is not in default hereunder, Tenant shall have the right, as a charge to the Improvement Allowance (as defined in the Tenant Work Letter attached hereto as Exhibit “D” and made part hereof), to install (i) a strip on the Project’s “monument” sign (“Monument Signage”) and (ii) one (1) building-top sign at the top of the Project (“Building-Top Signage”). The Monument Signage and the Building-Top Signage may be collectively referred to herein as “Tenant’s Signage”. The graphics, materials, size, color, design, lettering, lighting (if any), specifications and exact location of Tenant’s Signage (collectively, the “Signage Specifications”) shall be subject to the prior written approval of Landlord, which approval shall not be unreasonably withheld. In addition, Tenant’s Signage and all Signage Specifications therefore shall be subject to Tenant’s receipt of all required governmental permits and approvals, shall be subject to all applicable governmental laws and ordinances, and all covenants, conditions and restrictions affecting the Project. Tenant hereby acknowledges that, notwithstanding Landlord’s approval of Tenant’s Signage and/or the Signage Specifications therefor, Landlord has made no representations or warranty to Tenant with respect to the probability of obtaining such approvals and permits. In the event Tenant does not receive the necessary permits and approvals for Tenant’s Signage, Tenant’s and Landlord’s rights and obligations under the remaining provisions of this Lease shall not be affected. The cost of installation of Tenant’s Signage, as well as all costs of design and construction of Tenant’s Signage and all other costs associated with Tenant’s Signage, including, without limitation, permits, maintenance and repair, shall be the sole responsibility of Tenant. Notwithstanding anything to the contrary contained herein, in the event that at any time during the Term of this Lease, Tenant fails to occupy at least 15,000 square feet of the Premises, Tenant’s right to the Building-Top Signage shall thereupon terminate and Tenant shall remove the Building-Top Signage as provided in this Article 31 below. The rights to Tenant’s Signage shall be personal to the originally named Tenant and may not be transferred. Should the Signage require maintenance or repairs as determined in Landlord’s reasonable judgment, Landlord shall have the right to provide written notice thereof to Tenant and Tenant shall cause such repairs and/or maintenance to be performed within thirty (30) days after receipt of such notice from Landlord at Tenant’s sole cost and expense. Should Tenant fail to perform such maintenance and repairs within the period described in the immediately preceding sentence, Landlord shall have the right to cause such work to be performed and to charge Tenant, as Additional Rent, for the cost of such work. Upon the expiration or earlier termination of this Lease (or the termination of Tenant’s Building-Top Signage right as described above), Tenant shall, at Tenant’s sole cost and expense, cause the Tenant’s Signage to be removed from the monument and the exterior of the Project and shall cause the monument and the exterior of the Project to be restored to the condition existing prior to the placement of Tenant’s Signage. If Tenant fails to remove Tenant’s Signage and to restore the monument and the exterior of the Project as provided in the immediately preceding sentence within thirty (30) days following the expiration or earlier termination of this Lease (or the termination of Tenant’s Building-Top Signage as provided above), then Landlord may perform such work, and all costs and expenses incurred by Landlord in so performing such work shall be reimbursed by Tenant to Landlord within ten (10) days after Tenant’s receipt of invoice therefor. The immediately preceding sentence shall survive the expiration or earlier termination of this Lease.

-33-

ARTICLE 32

CONTINGENCY

This Lease is subject to and conditional upon Landlord entering into an agreement with New Vista Asset Management, the current tenant of a portion of the Premises, whereby such existing tenant agrees to terminate its existing lease prior to the scheduled date of expiration thereof upon terms acceptable to Landlord (the “Contingency”). If the Contingency is not satisfied, Landlord shall so notify Tenant, in which case this Lease shall be null and void, Landlord shall immediately refund the cash security deposit and return the Letter of Credit to Tenant and neither party shall have any further obligation to the other.

ARTICLE 33

OPTION TO EXTEND

(a) Option Right. Landlord hereby grants the Tenant named in this Lease (the “Original Tenant”) one (1) option (“Option”) to extend the Term for the entire Premises for a period of three (3) years (the “Option Term”), which Option shall be exercisable only by written notice delivered by Tenant to Landlord as set forth below. The rights contained in this Article 33 shall be personal to the Original Tenant and may only be exercised by the Original Tenant (and not any assignee, sublessee or other transferee of the Original Tenant’s interest in this Lease) if the Original Tenant occupies the entire Premises as of the date of Tenant’s Acceptance (as defined in Section 33(c) below).

(b) Option Rent. The rent payable by Tenant during the Option Term (“Option Rent”) shall be equal to 100% of the “Market Rent” (defined below). “Market Rent” shall mean the applicable Monthly Basic Rental, and all escalations, Direct Costs, additional rent and other charges at which tenants, as of the commencement of the Option Term, are entering into leases for non-sublease office space which is not encumbered by expansion rights and which is comparable in size, location and quality to the Premises in renewal transactions for a term comparable to the Option Term, which comparable space is located in office buildings comparable to the Project in San Diego, California, taking into consideration free rent, escalations, tenant improvements and brokerage commissions, and also taking into consideration the value of the existing improvements in the Premises to Tenant, as compared to the value of the existing improvements in such comparable space, with such value to be based upon the age, quality and layout of the improvements and the extent to which the same could be utilized by Tenant with consideration given to the fact that the improvements existing in the Premises are specifically suitable to Tenant.

(c) Exercise of Option. The Option shall be exercised by Tenant only in the following manner: (i) Tenant shall not be in default, and shall not have been in default under this Lease more than once, on the delivery date of the Interest Notice and Tenant’s Acceptance; (ii) Tenant shall deliver written notice (“Interest Notice”) to Landlord not more than twelve (12) months nor less than nine (9) months prior to the expiration of the Term, stating that Tenant is interested in exercising the Option; (iii) within fifteen (15) business days of Landlord’s receipt of Tenant’s written notice, Landlord shall deliver notice (“Option Rent Notice”) to Tenant setting forth the Option Rent; and (iv) if Tenant desires to exercise such Option, Tenant shall provide Landlord written notice within five (5) business days after receipt of the Option Rent Notice (“Tenant’s Acceptance”). Tenant’s failure to deliver the Interest Notice or Tenant’s Acceptance on or before the dates specified above shall be deemed to constitute Tenant’s election not to exercise the Option. If Tenant timely and properly exercises its Option, the Term shall be extended for the Option Term upon all of the terms and conditions set forth in this Lease, except that the rent for the Option Term shall be as indicated in the Option Rent Notice.

TENANT WORK LETTER

[VITAL THERAPIES, INC.]

This Tenant Work Letter shall set forth the terms and conditions relating to the renovation of the tenant improvements in the Premises. This Tenant Work Letter is essentially organized chronologically and addresses the issues of the renovation of the Premises, in sequence, as such issues will arise.

SECTION 1

LANDLORD’S INITIAL CONSTRUCTION IN THE PREMISES

Landlord has constructed, at its sole cost and expense, the base, shell and core (i) of the Premises, and (ii) of the floor of the Project on which the Premises is located (collectively, the “Base, Shell and Core”). Tenant has inspected and hereby approves the condition of the Premises and Base, Shell and Core, and agrees that, subject to construction of the Improvements, the Premises and the Base, Shell and Core shall be delivered to Tenant in its current “as-is” condition. The improvements to be initially installed in the Premises shall be designed and constructed pursuant to this Tenant Work Letter. Any costs of initial design and construction of any improvements to the Premises shall be an “Improvement Allowance Item”, as that term is defined in Section 2.2 of this Tenant Work Letter.

SECTION 2

IMPROVEMENTS

2.1 Improvement Allowance. Tenant shall be entitled to a one-time improvement allowance (the “Improvement Allowance”) in the amount of $477,950.00 (based on $25.00 per rentable square foot of the Premises) for the costs relating to the initial design and construction of Tenant’s improvements which are permanently affixed to the Premises (the “Improvements”) and the other Improvement Allowance Items described in Section 2.2 below. In no event shall Landlord be obligated to make disbursements pursuant to this Tenant Work Letter in a total amount which exceeds the Improvement Allowance and in no event shall Tenant be entitled to any credit for any unused portion of the Improvement Allowance not used by Tenant by the date which is sixty (60) days after the Commencement Date.

2.2 Disbursement of the Improvement Allowance. Except as otherwise set forth in this Tenant Work Letter, the Improvement Allowance shall be disbursed by Landlord (each of which disbursements shall be made pursuant to Landlord’s disbursement process) for costs related to the construction of the Improvements and for the following items and costs (collectively, the “Improvement Allowance Items”): (i) payment of the fees of the “Architect” and the “Engineers,” as those terms are defined in Section 3.1 of this Tenant Work Letter, and payment of the fees incurred by, and the cost of documents and materials supplied by, Landlord and Landlord’s consultants in connection with the preparation and review of the “Construction Drawings,” as that term is defined in Section 3.1 of this Tenant Work Letter; (ii) the cost of permits; (iii) the cost of any changes in the Base, Shell and Core required by the Construction Drawings; (iv) the cost of any changes to the Construction Drawings or Improvements required by applicable building codes (the “Code”); and (v) the “Landlord Coordination Fee”, as that term is defined in Section 4.3.2 of this Tenant Work Letter. However, in no event shall more than Three and 00/100 Dollars ($3.00) per usable square foot of the Improvement Allowance be used for the aggregate cost of items described in (i) and (ii) above; any additional amount incurred as a result of (i) and (ii) above shall be paid for by Tenant as part of the Over-Allowance Amount.

2.3 Standard Improvement Package. Landlord has established specifications (the “Specifications”) for the Project standard components to be used in the construction of the Improvements in the Premises (collectively, the “Standard Improvement Package”), which Specifications are available upon request. The quality of Improvements shall be equal to or of

EXHIBIT “D”

-1-

greater quality than the quality of the Specifications, provided that Landlord may, at Landlord’s option, require the Improvements to comply with certain Specifications.

SECTION 3

CONSTRUCTION DRAWINGS

3.1 Selection of Architect/Construction Drawings. Landlord shall retain an architect/space planner designated by Landlord (the “Architect”) to prepare the “Construction Drawings,” as that term is defined in this Section 3.1. Landlord shall also 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 and life safety work of the Tenant Improvements. 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 as reasonably determined by Landlord, and shall be subject to Landlord’s reasonable approval. Landlord’s review of the Construction Drawings as set forth in this Section 3, shall be for its sole purpose and shall not imply Landlord’s review of the same, or obligate Landlord to review the same, for quality, design, Code compliance or other like matters. Accordingly, notwithstanding that any Construction Drawings are reviewed by Landlord or its space planner, architect, engineers and consultants, and notwithstanding any advice or assistance which may be rendered to Tenant by Landlord or Landlord’s space planner, architect, engineers, and consultants, Landlord shall have no liability whatsoever in connection therewith and shall not be responsible for any omissions or errors contained in the Construction Drawings.

3.2 Final Space Plan. Tenant and the Architect have prepared the final space plan for Improvements in the Premises (collectively, the “Final Space Plan”), which Final Space Plan is attached hereto as Schedule 1 and has been approved by Landlord and Tenant.

3.3 Final Working Drawings. Based on the Final Space Plan, Landlord shall cause the Architect and the Engineers to complete the architectural and engineering drawings for the Premises, and the final architectural working drawings in a form which is complete to allow subcontractors to bid on the work and to obtain all applicable permits (collectively, the “Final Working Drawings”) and shall submit the same to Landlord for Landlord’s approval. Upon Landlord’s approval of Final Working Drawings, Landlord shall submit the Final Working Drawings to Tenant for Tenant’s approval, which shall not be unreasonably withheld. Tenant shall approve or disapprove any draft of Final Working Drawings within three (3) business days after Tenant’s receipt thereof. Tenant’s disapproval of Final Working Drawings shall include the reasonable reasons for Tenant’s disapproval. If Tenant fails to disapprove any draft of Final Working Drawings by written notice to Landlord within said three (3) business day period, said draft of Final Working Drawings shall be deemed to be approved by Tenant.

3.4 Permits. The Final Working Drawings shall be approved or deemed approved by Tenant (the “Approved Working Drawings”) prior to the commencement of the construction of the Improvements. Landlord shall cause the Architect to immediately submit the Approved Working Drawings to the appropriate municipal authorities for all applicable building permits necessary to allow “Contractor,” as that term is defined in Section 4.1, below, to commence and fully complete the construction of the Improvements (the “Permits”). No changes, modifications or alterations in the Approved Working Drawings may be made without the prior written consent of Landlord, which consent shall not be unreasonably withheld.

3.5 Time Deadlines. Tenant shall use its best efforts and all due diligence to cooperate with the Architect, the Engineers, and Landlord to complete all phases of the Construction Drawings and the permitting process and to receive the permits, and with Contractor for approval of the “Cost Proposal,” as that term is defined in Section 4.2 of this Tenant Work Letter, as soon as possible after the execution of the Lease, and, in that regard, shall meet with Landlord on a scheduled basis to be determined by Landlord, to discuss Tenant’s progress in connection with the same. The applicable dates for approval of items, plans and drawings as described in this Section 3, Section 4 below may be referenced to herein as the “Time Deadlines”.

Tenant shall approve and deliver the Cost Proposal to Landlord within three (3) business days of the receipt of the same, and upon receipt of the same by Landlord, Landlord shall be released by Tenant to purchase the items set forth in the Cost Proposal and to commence the construction relating to such items. The date by which Tenant must approve and deliver the Cost Proposal to Landlord shall be known hereafter as the “Cost Proposal Delivery Date.”

4.3 Construction of Improvements by Contractor under the Coordination of Landlord.

4.3.1 Over-Allowance Amount. On the Cost Proposal Delivery Date, Tenant shall deliver to Landlord an amount (the “Over-Allowance Amount”) equal to the difference between (i) the amount of the Cost Proposal and (ii) the amount of the Improvement Allowance (less any portion thereof already disbursed by Landlord, or in the process of being disbursed by Landlord, on or before the Cost Proposal Delivery Date). The Over-Allowance Amount shall be disbursed by Landlord prior to the disbursement of any then remaining portion of the Improvement Allowance, and such disbursement shall be pursuant to the same procedure as the Improvement Allowance. In the event that, after the Cost Proposal Delivery Date, any revisions, changes, or substitutions shall be made to the Construction Drawings or the Improvements, any additional costs which arise in connection with such revisions, changes or substitutions or any other additional costs shall be paid by Tenant to Landlord immediately upon Landlord’s request as an addition to the Over-Allowance Amount.

4.3.2 Landlord’s Retention of Contractor. Landlord shall independently retain Contractor, on behalf of Tenant, to construct the Improvements in accordance with the Approved Working Drawings and the Cost Proposal and Landlord shall coordinate the construction by Contractor, and Tenant shall pay a construction coordination fee (the “Landlord Coordination Fee”) to Landlord in an amount equal to the product of (i) five percent (5%) and (ii) an amount equal to the Improvement Allowance plus the Over-Allowance Amount (as such Over-Allowance Amount may increase pursuant to the terms of this Tenant Work Letter).

SECTION 5

COMPLETION OF THE IMPROVEMENTS

5.1 Substantial Completion. For purposes of this Lease, “Substantial Completion” of the Improvements in the Premises shall occur upon the completion of construction of the Improvements in the Premises pursuant to the Approved Working Drawings, with the exception of any punch list items and any tenant fixtures, work-stations, built-in furniture, or equipment to be installed by Tenant.

5.2 Delay of the Substantial Completion of the Premises. Except as provided in this Section 5, the Commencement Date and Tenant’s obligation to pay rent for the Premises shall occur as set forth in the Lease. However, if there shall be a delay or there are delays in the Substantial Completion of the Improvements in the Premises as a result of the following (collectively, “Tenant Delays”):

5.2.1 Tenant’s failure to comply with the Time Deadlines;

EXHIBIT “D”

-3-

5.2.2 Tenant’s failure to timely approve or not approve (stating the reasons therefor) any matter requiring Tenant’s approval;

5.2.3 A breach by Tenant of the terms of this Tenant Work Letter or the Lease;

5.2.7 Changes to the Base, Shell and Core required by the Approved Working Drawings; or

5.2.8 Any other acts or omissions of Tenant, or its agents, or employees;

then, notwithstanding anything to the contrary set forth in the Lease or this Tenant Work Letter and regardless of the actual date of the Substantial Completion of Improvements in the Premises, the date of Substantial Completion thereof shall be deemed to be the date that Substantial Completion would have occurred if no Tenant Delay or Delays, as set forth above, had occurred.
