LEASE AGREEMENT

This LEASE AGREEMENT (“Lease”), dated for reference purposes only as of the date set forth in provision (q) of the Fundamental Lease Provisions, is made and entered into by and between PEPPER LANE—GREAT OAKS, LLC, a California limited liability company (“Landlord”), and IKOS SYSTEMS, INC., a Delaware corporation (“Tenant”), who agree as follows:

ARTICLE 1—PREMISES

1.1 Lease of Premises. Landlord leases to Tenant, and Tenant leases from Landlord, the Premises described in provision (c)of the Fundamental Lease Provisions.

1.2 Remeasurement of Premises. Within thirty (30)days following the occurrence of the Commencement Date, Landlord shall measure the Premises, measured from the outside glass to the outside glass of the Building but not including the covered dock, patio areas or the exterior drip lines. In the event that such measurement of the Premises by Landlord indicates that the Premises contains in excess of or lower than the RSF set forth in provision (c) of the Fundamental Lease Provision, any payments due to either Landlord or Tenant from the other party based upon the amount of square feet contained in the Premises shall be proportionally, retroactively and prospectively reduced or increased, as appropriate, to reflect the actual RSF of the Premises as measured by Landlord pursuant to the provision of this Section 1.2, and the parties shall execute an amendment to this Lease consistent with the foregoing.

ARTICLE 2—TERM

2.1 Effective Date. The Lease will become effective when fully executed and delivered by Landlord and Tenant.

2.2 Term of Lease. The term of the Lease (“Term”) shall be for the term set forth in provision (d) of the Fundamental Lease Provisions beginning on the Commencement Date, as such term is defined below, and, unless sooner terminated as hereinafter provided, ending on the Expiration Date specified in provision (e) of the Fundamental Lease Provisions.

2.3 Commencement Date. The Term of this Lease and Tenant’s obligation to pay the Rent, as such term is defined below, shall commence on the earliest of (a) the date Tenant, or any person occupying any portion of the Premises with Tenant’s permission, commences business operations from the Premises (or any portion thereof, (b) the date the Base Building and the Tenant Improvements are Substantially Completed, or (c) the date the Base Building and the Tenant Improvements would have been Substantially Completed except for Tenant Delays (“Commencement Date”). The terms “Base Building,” “Tenant Improvements,” “ Substantially Completed” and “Tenant Delays” are defined in the Work Letter Agreement attached hereto as Exhibit “B” and made a part hereof.

2.4 Delivery of Premises. The Premises shall be delivered by Landlord to Tenant in the condition required by the Work Letter Agreement which is attached hereto as Exhibit “B”. Delay of the Commencement Date to the extent not attributable to Tenant Delays and/or Force Majeure Delays shall be Tenant’s sole remedy for any delay in constructing the Base Building and the tenant Improvements or making the Premises ready for occupancy Tenant understands that it is in Landlord’s best economic interests to have the Tenant Improvements completed as soon as reasonably possible in order to have the Commencement Date occur; as early as possible, and Tenant understands that to the extent that the Tenant Improvements are not completed because of Tenant Delays and/or Force Majeure Delays, the Commencement Date will nevertheless occur on the date the Tenant Improvements would have been completed except for Tenant Delays and/or Force Majeure Delays.

Notwithstanding anything to the contrary set forth in this Lease, in the event Landlord has not delivered the Premises to Tenant with the Tenant Improvements Substantially Completed by April 1, 2001 (the “Outside Delivery Date”), which Outside Delivery Date shall be extended one (1) day for each day of delay incurred by Landlord in the Substantial Completion of the Tenant Improvements due to Tenant Delays and Force Majeure Delays, Tenant shall have the right to elect to terminate the Lease by delivery to Landlord of a notice (the “Termination Notice”), which termination shall be effective five (5) business days after Tenant’s delivery of the Termination Notice to Landlord, unless within such five (5) business day period Landlord shall deliver to Tenant the Premises with the Tenant

Improvements Substantially Completed therein. Pursuant to the termination of the Lease as set forth herein, neither party shall have any further obligation to the other under this Lease.

2.5 Early Entry into Building. Tenant may enter into the premises, upon receipt of Landlord’s consent, for purposes of installing its network cabling, telecommunications and furniture systems. Such early entry shall not advance the Commencement Date, provided (a) Tenant does not commence business operations from any part of the Premises, and (b) Tenant’s early entry does not interfere with, or delay, the completion of the Tenant Improvements. If Tenant is allowed early entry, Landlord shall not be responsible for, and Tenant, prior to any such entry by Tenant or Tenant’s Employees (as defined in ARTICLE 7), shall obtain insurance covering any loss caused by Tenant or those entering the Premises on behalf of Tenant to install Tenant’s network cabling, telecommunications and furniture systems, including theft, damage or destruction to any work or material installed or stored by Tenant or any contra ctor or individual, or for any injury to Tenant or Tenant’s Employees or to any other person and provided further that Landlord shall have the right to post the appropriate notices of non-responsibility and to require Tenant to provide Landlord with evidence that Tenant has fulfilled its obligation to provide insurance pursuant to ARTICLE 12. To the extent any such early entry actually delays the Substantial Completion by landlord of the Tenant Improvements, such delay shall constitute a Tenant Delay.

2.6 Notice of Commencement Date. Landlord may send Tenant notice of the occurrence of the Commencement Date (including the number of RSF contained in the Premises) in the form of the attached Exhibit “C”, which notice Tenant shall acknowledge by executing a copy of the notice and returning it to Landlord. If Tenant fails to; sign and return the notice to Landlord within ten (10) days of receipt of the notice from Landlord, the notice as sent by Landlord shall be deemed to have correctly set forth the Commencement Date. Failure of Landlord to send such notice shall have no effect on the Commencement Date.

2.7 Options to Extend. Tenant’s rights and obligations with respect to extending the Term of this Lease are set forth in Exhibit “F” attached hereto .

ARTICLE 3—RENT

3.1 Base Rent. Tenant agrees to pay Landlord, as rent (“Base Rent”) for the Premises, monthly Base Rent in the amount specified in provision (g) of the Fundamental Lease Provisions. Such Monthly Base Rent shall be paid monthly in advance beginning on the Commencement Date as set forth in provision (1) of the Fundamental Lease Provisions and on or before the first day of each calendar month thereafter during the entire Term. In addition to the foregoing payments, Tenant shall also pay all other items of additional rent set forth in this Lease.

3.2 Definition of Rent. Any and all payments of Base Rent and any and all payments of additional rent, including without limitation, taxes, fees, charges, costs, expenses, insurance obligations, late charges, assessments, Personal Property Taxes, Real Property Taxes, and all other payments, disbursements or reimbursements (collectively “Rent”) which are attributable to, payable by or the responsibility of Tenant under the Lease shall constitute “Rent” within the meaning of California Civil Code Section 195.1(a). Any Rent payable To Landlord by Tenant for any fractional month shall be prorated based on the actual number of days in the applicable month. All payments owed by Tenant under the Lease shall be paid to Landlord in Lawful money of the United States of America at the location specified by Landlord pursuant to ARTICLE 32 of the Lease. All payments shall be paid without deduction, set-off or counterclaim, except as otherwise expressly provided herein.

3.3 Late Charge. Landlord and Tenant acknowledge that the late payment by Tenant of Rent will cause the Landlord to incur damages, including administrative costs, loss of use of the overdue funds and other costs, the exact amount of which would be impractical and extremely difficult to fix. Landlord and Tenant agree that if Landlord does not receive a payment within five (5) days after the date such payment is due, Tenant shall pay to Landlord a late charge equal to five percent (5%) of the overdue amount and the overdue amount shall bear interest at the Interest Rate (as such term is defined below), from the date five (5) days after payment of such amount was due until Landlord receives the overdue payment. Acceptance of the late charge by Landlord shall not cure or waive Tenant’s default nor prevent landlord from exercising, before or after such acceptance, any of the rights and remedies for a default provided by this Lease or at law. Payment of the late charge is not an alternative means of performance of Tenant’s obligation to pay Rent at the times specified in this Lease. Tenant will be liable for the late charge regardless of whether Tenant’s failure to pay the Rent when due constitutes a default under the Lease and regardless of whether Landlord sent Tenant an invoice for such Rent and/or late charge. The term “Interest Rate” shall mean the lower of (a) the maximum interest rate permitted by law or (b) two percent (2%) of the above the rate

publicly announced from time to time by Bank of America N.T. & S.A. (or if Bank of America N.T. & S.A. ceases to exist, then the largest bank headquartered in the State of California) (“Bank”) as its Reference Rate. If the use of the announced Reference Rate is discontinued by the Bank, then the reference to Reference Rate shall mean the announced rate charged by the Bank which is from time to time substituted for such Reference Rate. Whenever interest is required to be paid under this Lease, the interest shall be calculated from the date five (5) days after the payment was due or should have been due if correctly assessed or estimated (or any overcharge paid), until the date payment is made or the refund is paid or is credited against rent next due.

3.4 Disputes as to Payments of Rent. Tenant agrees to pay the Rent required under this Lease within the time limits set forth in this Lease. If Tenant receives from Landlord an invoice or statement, which invoice is sent by Landlord in good faith, and Tenant in good faith disputes whether all or any part of such Rent is due and owing, Tenant shall nevertheless pay to Landlord the amount of the Rent indicated on the invoice or statement until Tenant receives a final judgment from a court of competent jurisdiction (or when arbitration is permitted or required, receives a final award from an arbitrator) relieving or mitigating Tenant’s obligation to pay such Rent. In such instance where Tenant disputes its obligations to pay all or part of the Rent indicated on such invoice or statement, Tenant shall, concurrently with the payment of such Rent, provide Landlord with a letter or notice entitled “Payment Under P rotest” specifying in detail why Tenant is not required to pay all or part of such Rent. Tenant will be deemed to have waived its right to contest any past payment of Rent unless it has filed a lawsuit against Landlord (or when arbitration is permitted or required, filed for arbitration and has served Landlord with notice of such filing), and has served a summons on Landlord, within one (1) year of such payment.

3.5 Operating Expense Adjustments. Beginning with the Commencement Date and thereafter during the Term of this Lease, Tenant shall pay, in addition to the Base Rent computed due pursuant to Section 3.1, an additional sum as an operating expense adjustment (“Operating Expense Adjustment”) equal to Tenant’s Pro Rata Share, as set forth in provision (i) of the fundamental Lease Provisions, of the Operating Expenses (as hereinafter defined) for the Premises.

3.6 Procedure for Payment of Operating Expense Adjustments. Tenant shall pay the Operating Expense Adjustment as follows:

(a) Landlord may, from time to time by ten (10) days’ notice to Tenant, reasonably estimate in advance the amounts Tenant shall owe on a monthly basis for the Operating Expense Adjustment for any full or partial calendar year of the Term. In such event, Tenant shall pay such estimated amounts, o a monthly basis, on or before the first day of each calendar month, together with Tenant’s payment of Base Rent. Such estimate may be reasonably adjusted from time to time by Landlord by written notice to Tenant.

(b) Within one hundred twenty (120) days after the end of each calendar year, Landlord shall provide a statement (the “ Statement”) to Tenant showing: (i) the amount of actual Operating Expenses for such calendar year, (ii) any amount paid by Tenant toward the Operating Expenses on an estimated basis, and (iii) any revised estimate of Tenant’s obligations for excess Operating Expenses for the current calendar year.

(c) If the Statement shows that Tenant’s estimated payments were less than Tenant’s actual obligations for Operating Expenses for such year, Tenant shall pay the difference. If the Statement shows an increase in Tenant’s estimated payments for the current calendar year, Tenant shall pay the difference between the new and former estimates, for the period from January 1 of the current calendar year through the month in which the Statement is sent. Tenant shall make such payments within thirty (30) days after Landlord sends the Statement.

(d) If the Statement shows that Tenant’s estimated payments exceeded Tenant’s actual obligations for Operating Expenses, Tenant shall receive a credit of such difference against payment(s)of Rent next due. If the Term shall have expired and no further Rent shall be due, Tenant shall receive a refund of such difference within thirty (30) days after Landlord sends the Statement .

(e) No delay by Landlord in providing the Statement (or separate statements) shall be deemed a default by Landlord or a waiver of Landlord’s right to require payment of Tenant’s obligations for actual or estimated Operating Expenses.

(f) If Tenant’s obligation to pay Operating Expense Adjustments commences other than on January l, or ends other than on December 31, Tenant’s obligation to pay estimated and actual amounts toward

Operating Expenses for such, first or final calendar years shall be prorated to reflect the portion of such years included within the period for which Tenant is obligated to pay Operating Expense Adjustment.

Such proration shall be made by multiplying the total estimated or actual (as the case may be) Operating Expends for such calendar years by a fraction, the numerator which shall be the number of days within the period for which Tenant is obligated to pay Operating Expenses Adjustments during such calendar year, and the denominator of which shall be the total number of days in such year.

3.7 Certain Defined Terms. Tenant’s Pro Rata Share as of the Commencement Date is stipulated to be the percentage set forth in provision (i) of the Fundamental Lease Provisions. “Operating Expenses” are defined to be the sum of all costs, expenses, and disbursements, of every, kind and nature whatsoever, and the Real Property Taxes (as hereinafter defined in ARTICLE 22), which shall be the obligation of Landlord in connection with the operation, servicing, maintenance and repair of the Premises pursuant to this Lease, including, but not limited to, the following:

(f) Any auditor’s fees for accounting provided for the operation and maintenance of the Building;

(h) A property management fee on an annual basis equal to one and one-half percent (1-1/.2%) of the Base Rent then in effect under this Lease for such year;

(i) The annual amortization (amortized over the useful life) of costs, including financing costs, if any, incurred by Landlord after the issuance of the temporary certificate of occupancy for the Building for any capital improvements installed or paid for by Landlord and required by any new (or change in) laws, roles or regulations of any governmental or quasi-governmental authority (collectively “Laws”);

(j) The annual amortization (amortized over the useful life) of costs, including financing costs, if any, of any equipment, device or capital improvement purchased or incurred as a labor-saving measure or to affect other economies in the operation or maintenance of the Building (provided the annual amortized cost does not exceed the higher or the actual cost savings realized or the cost savings reasonably anticipated to be available);

(k) The annual amortization (amortized over the useful life) of costs, if any, incurred after completion of the Building for the replacement of exterior perimeter window draperies or blinds provided by Landlord;

(1) All insurance premiums and other charges (including the amount of any deductible payable by Landlord with respect to damage or destruction to all or any portion of the Building) incurred by Landlord with respect to maintaining the types and amounts of insurance set forth in Section 12.2(b); provided, however, (i) subject to the provisions of Section 12.2(c), the amount of Landlord’s insurance premiums to be included in Operating Expenses for earthquake coverage shall not exceed $.05 per RSF of the Building per month for the first full year of the Lease Term and the amount of increase in Landlord’s insurance premiums for earthquake

coverage to be included in Operating Expenses during the Lease Term subsequent to the first full year of the Lease Term shall not exceed three percent (3%) per annum on a compounded, cumulative basis, and (ii) in the event of the occurrence of an earthquake affecting the Premises during the Lease Term, the amount of the deductible for earthquake insurance (“Earthquake Deductible”) to be included in Operating Expenses for such year shall be the amount of Earthquake Deductible then in effect based on the schedule set forth in Section 12.2(c);

(m) All Real Property Taxes; and

In the even Tenant shall elect to exercise the Extension Option(s) set forth in Exhibit “F” the amount of the Earthquake Deduct ible then effect during the first (1st) full year of the applicable Extension Period shall again be one hundred percent (100%) subject to the ten percent (10)%) reduction each year thereafter.

Each party shall cause each policy for property damage insurance to include a provision permitting such a release of liability (commonly referred to as a waiver of subrogation endorsement) as described

above; provided, that if an insurer will not include such a provision in such policy or if the inclusion of such a provision would involve all additional premium in excess of fifteen percent (15%) of the premium which would otherwise be charged, the party carrying the policy shall so advise the other party within a reasonable time. If the other party notifies the party carrying the policy that it desires such a provision to be included in the policy, the party carrying the policy shall use its best efforts to cause such a provision to be so included provided the other party shall promptly pay all premiums therefore over and above said fifteen percent (15%) excess premium.

(b) Repairs Which Cannot Be Completed Within One (1) Year. If all such repairs to the Premises or the Building cannot, in Landlord’s reasonable judgment be completed within one (1) year knowing the date of such damage or destruction without the payment of overtime or other premiums, Landlord shall notify Tenant of such determination and Landlord may, at Landlord’s sole and absolute discretion, upon written notice to Tenant given within sixty (60) days of the occurrence of such damage or destruction, elect to repair such damage or destruction at Landlord’s expense, in which event, this Lease shall continue in full force and effect but the Rent shall be proportionately reduced as hereinabove provided in Section l3.1(a). If Landlord does not elect to make such repairs, then either Landlord or Tenant may, upon written notice to the other party given within ninety (90) da ys after the occurrence of such damage or destruction, elect to terminate this Lease as of the date of such damage or destruction.

14.1 Permanent Taking.—When Lease Can Be Terminated. If (a) the whole of the Premises, or so much of the Premises as to render the balance unusable by Tenant, shall be taken under the power of eminent domain, or (b) a partial taking shall occur under the power of eminent domain so as to materially interfere with Tenant’s use of the Premises, the Lease shall automatically terminate as of the date of final judgment in such condemnation, or as of the date possession is taken by the condemning authority, whichever is earlier. A sale by Landlord under threat of condemnation shall constitute a “taking” for the propose of this ARTICLE 14. No award for any partial or entire taking shall be apportioned and Tenant assigns to Landlord any award which may be made in such taking or condemnation, together with all rights of Tenant to such award, including, without limitation, any award or compensation for the v alue of all or any part of the leasehold estate; provided that nothing contained in this ARTICLE 14 shall be deemed to give Landlord any interest in or to require Tenant to assign to Landlord any award made to Tenant for (a) the taking of Tenant’s Personal Property, (b) interruption of or damage to Tenant’s business, or (c)Tenant’s unamortized cost of the Tenant Improvements to the extent paid for by Tenant. Furthermore, nothing contained in this ARTICLE 14 shall limit or restrict the right of Tenant to file an individual claim against the condemning authority for its individual award.

14.2 Permanent Taking 1—When Lease Cannot Be Terminated.

14.3 Temporary Taking. No temporary taking of the Premises or any part of the Premises and/or of Tenant’s rights to the Premises or under this Lease shall terminate this Lease or give Tenant any right to any abatement of any payments owed to Landlord pursuant to this Lease; any award made to Tenant by reason of such temporary, taking shall belong entirely to Tenant.

14.4 Exclusive Remedy. This ARTICLE 14 shall be Tenant’s sole and exclusive remedy in the event of a taking or condemnation. Tenant hereby waives the benefit of California Code of Civil Procedure Section 1265.130.

14.5 Release Upon Termination. Upon termination of the Lease pursuant to this ARTICLE 14, Tenant and Landlord hereby agree to release each other from any and all obligations and liabilities with respect to the Lease to the same extent as if the Lease had expired on the date of such termination, except for such obligations and liabilities which arise or accrue prior to such termination, and except for any contingent obligations of the parties which, pursuant to the other terms of this Lease, would have survived the expiration or termination hereof:

ARTICLE 15—TENANT DEFAULT

Each of the following shall be an Event of Default by Tenant and a material breach of the Lease:

(a) Tenant shall fail to make any payment owed by Tenant under the Lease, as and when due, and where such failure is not cured within a period of five (5) days following notice to Tenant from Landlord.

(b) The abandonment of the Premises by Tenant, or the vacation (defined to be thirty (30) or more days of continued absence from the Premises) of the Premises by Tenant.

(c) Tenant shall fail to observe, keep or perform any of the terms, covenants, agreements or conditions under the Lease that Tenant is obligated to observe or perform, other than that described in such paragraph (a) above, for a period of thirty (30) days after notice to Tenant of said failure; provided however, that if the nature of Tenant’s default is such that more than thirty (30) days are reasonably required for its cure, then Tenant

shall not be deemed to be in default under the Lease if Tenant shall commence the cure of such default so specified within said thirty (30) day period and shall diligently prosecute the same to completion.

(d) To the extent permitted by law, a general assignment by Tenant for the benefit of creditors, or the filing by or against Tenant of any proceeding under an insolvency or bankruptcy law, unless in the case of a proceeding filed against Tenant the same is dismissed within ninety (90) days, or the appointment of a trustee or receiver to take possession of all or substantially all of the assets of Tenant unless possession is restored to Tenant within sixty (60) days, or any execution, attachment, levy, sale or other judicially authorized seizure or dismissal of Tenant’s leasehold interest hereunder or of all or substantially all of Tenant assets located upon the Premises or of Tenant’s interest in this Lease, unless in the case of an attachment, levy or seizure the same shall be discharged within sixty (60) days.

ARTICLE 16—LANDLORD REMEDIES AND RIGHT’S

16.1 Termination of Lease. In the event of any Event of Default by Tenant, Landlord shall have the right, in addition to all other rights available to Landlord under this Lease now or later permitted by law or equity, to terminate this Lease by providing Tenant with a notice of termination or, at Landlord’s election, to terminate Tenant’s right of possession without terminating this Lease. Upon termination of this Lease, Landlord may recover as damages the Rent that Landlord would have received had Tenant not defaulted, plus attorneys’ fees, court costs, additional brokerage costs, additional design and construction costs, and any other costs reasonably incurred by Landlord to mitigate damages. Landlord agrees to use commercially reasonable efforts to mitigate damages, as well as any other damages to which Landlord is entitled to recover under any statute now or later in effect, including those damages provided in California Civil Code Section 1951.2. Landlord’s damages include (to the extent not duplicative of the foregoing) the worth, at the time of any award, of the amount by which the unpaid Rent (which may, at Landlord’s election be accelerated to be due and payable in full as of the Event of Default and recoverable in damages as a lump sum) for the balance of the term after the time of the award exceeds the amount of the rental loss that the Tenant proves could be reasonably avoided. The worth at the time of award shall be determined by discounting to present value such amount at one percent (1%) more than the discount rate of the Federal Reserve Bank in San Francisco in effect at the time of the award. All damages to which Landlord is entitled shall earn interest at the interest Rate.

16.2 Continuation of Lease. In accordance with California Civil Code Section 1951.4 (and any successor statute), Tenant acknowledges that in the event Tenant has breached this Lease and abandoned the Premises, this Lease shall continue in effect for so long as Landlord does not terminate the Lease, which Landlord shall not be required to do, or be deemed to have done without unequivocal written notification to Tenant of such election, even though Landlord may have terminated Tenant’s right to possession (which will correspondingly terminate Tenant’s right to sublease and/or assign), and Landlord may enforce all its rights and remedies under this Lease, including the right to recover Rent as it becomes due under this Lease. Acts of maintenance or preservation or efforts to relet (including reletting) the Premises or the appointment of a receiver upon initiative of Landlord to protect Landlord’ s interest under this Lease shall not constitute a termination of this Lease. In addition to its other rights under this Lease, Landlord has the remedy described in California Civil Code Section 1951.4 (Landlord may continue the Lease in effect after Tenant’s breach and abandonment and recover Rent (as defined in Section 3.2) as it becomes due, if Tenant has the right to sublet or assign, subject only to reasonable limitations).

16.3 Right of Entry. In the event of any default by Tenant, Landlord shall also have the right, with or without terminating this Lease, to enter the Premises and remove all persons and personal property from the Premises, such property being removed and stored in a public warehouse or elsewhere at Tenant’s sole cost and expense. No removal by Landlord of any persons or property in the Premises shall constitute an election to terminate this Lease. Such an election to terminate may only be made by Landlord in writing. Landlord’s right of entry shall include the right to remodel the Premises and re-let the Premises. All costs incurred in such entry and re-letting shall be paid by Tenant. Rents collected by Landlord from any other tenant which occupies the Premises shall be offset against the amounts owed to Landlord by Tenant. Tenant shall be responsible for any amounts not recovered by Landlord from any other tenant. Any payments made by Tenant shall be credited to the amounts owed by Tenant in the sole order and discretion of Landlord, irrespective of any designation or request by Tenant. No entry by Landlord shall prevent Landlord from later terminating the Lease by written notice.

16.4 Right to Perform. If an Event of Default occurs, Landlord may perform such covenant or condition at its option, after notice to Tenant. All costs incurred by Landlord in so performing shall immediately be

reimbursed to Landlord by Tenant, together with interest at the Interest Rate computed from the date incurred by Landlord. Any performance by Landlord of Tenant’s obligations shall not waive or cure such default.

16.5 Remedies Not Exclusive. The rights and remedies of Landlord and Tenant set forth herein are not exclusive, and Landlord and Tenant may exercise any other right or remedy available to it under this Lease, at law or in equity except as otherwise expressly set forth herein.

16.6 Assignment of Rents. Tenant assigns to Landlord all subrents and other sums falling due from subtenants, licensees and concessionaires (herein called “ subtenants”) during any period in which Tenant is in default and Tenant shall not have any right to such sums during that period. Landlord may at Landlord’s election reenter the Premises, without terminating this Lease, and either or both collect these sums or bring action for the recovery of the sums directly from such obligors. Landlord shall receive and collect all subrents and proceeds from reletting, applying them in the following order of priority: (a) to the payment of all costs incurred by Landlord in restoring the Premises to good order and repair, or in remodeling, renovating or otherwise preparing the Premises for reletting, (b) to the payment of all costs (including, without limitation, attorneys’ fees or brokers’ commissions o r both) incurred by Landlord in reletting the Premises, and in fulfilling Landlord’s obligations with respect to such reletting (such as, by way of example, providing services or utilities), (c) to the payment of Rent (and any interest thereon) due and unpaid hereunder, and (d) the balance, if any, to the payment of future Rent as the same may become due hereunder. Tenant shall nevertheless pay to Landlord on the due date specified in this Lease the equivalent of all sums requested of Tenant under this Lease, plus Landlord’s expenses, less proceeds of the sums assigned and actually collected under this provision.

16.7 Waiver of Default. No waiver by Landlord or Tenant of any violation or breach of any of the terms, provisions and covenants herein contained shall be deemed or construed to constitute a waiver of any other or later violation or breach of the same or any other of the terms, provisions, and covenants herein contained. Forbearance by Landlord in enforcement of one or more of the remedies herein provided upon an event of default shall not be deemed or construed to constitute a waiver of such default. The acceptance or any Rent hereunder by Landlord following the occurrence of any default, whether or not known to Landlord, shall not be deemed a waiver of any such default, except only a default in the payment of the Rent so accepted.

16.8 Bankruptcy. If Tenant assumes this Lease and proposes to assign the same pursuant to the provisions of the Bankruptcy Code, 11 U.S.C. § 101 et seq., or any successor statute (the “Bankruptcy Code”) to any person or entity who shall have made a bona fide offer to accept an assignment of this Lease on terms acceptable to Tenant then notice of such proposed assignment, setting forth (a) the name and address of such person, (b) all of the terms and conditions of such offer, and (c) the adequate assurance to be provided Landlord to assure such person’s future performance under this Lease, including, without limitation, the assurance referred to in Section 365(b)(3) of the Bankruptcy Code, shall be given to Landlord by Tenant no later than twenty (20) days after receipt by Tenant but in any event no later than ten (10) days prior to the date that Tenant shall make application to a court of competen t jurisdiction for authority and approval to enter into such assignment and assumption, and Landlord shall thereupon have the prior right and option, to be exercised by notice to Tenant given at any time prior to the effective date of such proposed assignment, to accept an assignment of this Lease upon the same terms and conditions and for the same consideration, if any, as the bona fide offer, made by such person, less any brokerage commissions which may be payable out of the consideration to be paid by such person for the assignment of this Lease.

ARTICLE 17—ATTORNEYS’ FEES

If either Landlord or Tenant commences or engages in, or threatens to commence or engage in, any action or litigation or arbitration against the other party arising out of or in connection with the Lease, the Premises or the Building, including but not limited to, any action for recovery of any payment owed by either party under the Lease, or to recover possession of the Premises, or for damages for breach of the Lease, the prevailing party shall be entitled to have and recover from the losing party reasonable attorneys’ fees any other costs incurred in connection with the action and in preparation for said action.

ARTICLE 18—SUBORDINATION, ATTORNMENT AND NON-DISTURBANCE

18.1 Subordination Attornment and Non-Disturbance. This Lease shall be subject and subordinate at all times to the lien of any mortgage, deed of trust or other security interest (“mortgage”) now existing or hereafter executed in any amount which effects the Premises or for which Landlord’s interest or estate in the Premises is

specified as security. Notwithstanding the foregoing, Landlord shall have the right to subordinate or cause to be subordinated any such liens to this Lease. In the event that any mortgage is foreclosed or a conveyance in lieu of foreclosure is made for any reason, Tenant shall, notwithstanding any subordination, have the right to attorn to, and shall attorney to, and become Tenant of, the successor in interest to Landlord on all of the terms and conditions contained in this Lease. Tenant covenants and agrees to execute and deliver, within five (5) days of request by Landlord and in the form requested by Landlord, any additional instruments evidencing the priority or subordination of this Lease with respect to the lien of any such mortgage. A condition precedent to the subordination herein and to the execution of any future instrument of subordination is that Landlord shall obtain for the benefit of Tenant a non-disturbance and adornment agreement from the lender in whose favor the subordination is given, in content reasonably acceptable to Tenant. Tenant shall promptly review and execute any non-disturbance agreement submitted to Tenant by Landlord which meets with the requirements of this Section, and shall promptly advise Landlord if Tenant disapproves of any such proposed agreement. Said agreement shall provide that (a) Tenant will not be named or joined in any proceeding to enforce the mortgage unless such is required by law in order to perfect the proceeding, (b) enforcement of the mortgage will not terminate the Lease or disturb Tenant in the possession and use of the Premises, unless Tenant is in default beyond the period provided in the Lease to remedy the default, and (c) any party succeeding to the interest of the Landlord as a result of the reinforcement of the mortgage shall be bound to the Tenant under all the terms, covenants and conditions of this Lease from and after the date of succeeding to the Landlord’s interest under this Lease and for the balance of the term of the Lease, except that in no event will such party be liable for claims arising prior to the date of succession, or be subject to offsets or offsets or defenses Tenant might have against a prior Landlord, or be bound by any amendment to the Lease made without the lender’s consent, or be liable for completion of construction of any improvements, or be bound by any Rent payments made more than one month in advance to the prior Landlord, and (d)Tenant is obligated to attorn to any party succeeding to the interest of the Landlord as a result of the enforcement of a mortgage.

Landlord hereby represents and warrants that, as of the date hereof, there are no mortgages in effect which affect the Premises or for which Landlord’s interest or estate in the Premises is specified as security.

18.2 Landlord’s Right to Assign. Landlord’s interest in the Lease may be assigned to any mortgagee or trust deed beneficiary as additional security. Nothing in this Lease shall empower Tenant to do any act without Landlord’s prior consent which can, shall or may encumber the title of the owner of all or any part of the Premises.

18.3 Non-Disturbance. Notwithstanding any of the provisions of this ARTICLE 18 to the contrary, Tenant shall be allowed to occupy the Premises, subject to the conditions of this Lease, and this Lease shall remain in effect until an event of default occurs, or until Tenant’s rights are modified because of a condemnation proceeding pursuant to ARTICLE 14, or because of the occurrence of damage and destruction pursuant to ARTICLE 13 of the Lease.

ARTICLE 19—RULES AND REGULATIONS

Tenant shall faithfully observe and comply with the Building roles and regulations (“Rules and Regulations”), a copy of which is attached to this Lease as Exhibit “ D”, and all reasonable modifications and additions to the Rules and Regulations from time to time put into effect by Landlord; provided, however, that no modifications or additions to the Rules and Regulations shall interfere with Tenant’s permitted use of the Premises as set forth in Section 5.1.

ARTICLE 20—HOLDING OVER

20.1 Surrender of Possession. Tenant shall surrender possession of the Premises immediately upon the expiration of the Term or earlier termination of Lease. If Tenant shall continue to occupy or possess the Building after such expiration or termination without the consent of Landlord, then unless Landlord and Tenant have otherwise agreed in writing, Tenant shall be a tenant from month-to-month. All the terms, provisions and conditions of the Lease shall apply to this month-to-month tenancy except those terms, provisions and conditions pertaining to the Term and except that the monthly Base Rent shall be immediately adjusted upward upon the expiration or termination of the Lease to equal the greater of (a) one hundred fifty percent (150%) of the then fair market rent for similar commercial space, as determined by Landlord, or (b) one hundred fifty percent (150%) of the monthly Base Rent for the Premises in effect unde r this Lease during the month which includes the day immediately prior to the date of the expiration or termination of the Lease (“Base Term Rent”). This month-to-month tenancy may be

terminated by Landlord or Tenant upon ten (10) days’ prior notice to the non-terminating party. In the event that Tenant fails to surrender the Premises immediately upon the expiration of the Term or earlier termination of the Lease, then Tenant shall indemnify and hold Landlord harmless against all damages, loss or liability resulting from or arising out of Tenant’s failure to surrender the Premises, including, but not limited to, any amounts required to be paid to any tenant or prospective tenant who was to have occupied the Premises after said termination or expiration of any related attorneys’ fees and brokerage commissions.

20.2 Payment or Money After Termination. No payment of money by Tenant to Landlord after the termination of the Lease by Landlord or after the giving of any notice of termination to Tenant by Landlord which Landlord is entitled to give Tenant under the Lease, shall reinstate, continue or extend the Term of the Lease or shall affect any such notice given to Tenant prior to the payment of such money, it being agreed that after the service of such notice or the commencement of any suit by Landlord to obtain possession of the Premises, Landlord may receive and collect when due any and all payments owed by Tenant under the Lease, and otherwise exercise its rights and remedies the making of any such payments by Tenant shall not waive such notice, or in any manner affect any pending suit or judgment obtained.

ARTICLE 21—INSPECTIONS AND ACCESS

If Tenant shall not be personally present to open and permit an entry into the Premises at any time when such entry by Landlord is necessary or permitted under the Lease, Landlord may enter by means of a master key without liability to Tenant except for any failure to exercise due care for Tenant’s Personal Property, and without affecting the Lease. In any event, any such entry shall be accomplished as expeditiously as reasonably possible and in a manner so as to cause as little interference to Tenant as reasonably possible.

ARTICLE 22—REAL AND PERSONAL PROPERTY TAXES

Subject to Tenant’s right to contest as set forth below, Tenant shall pay the Real Property Taxes now or hereafter levied against the Premises and the Building during the Term of this Lease. Tenant may contest the amount or validity of such Real Property Taxes by appropriate proceedings; provided, however, that Tenant shall promptly pay such taxes unless such proceedings shall operate to prevent or stay the collection of the tax so contested. Landlord shall join in any such proceedings if any law shall so require, providing that Tenant shall indemnify Landlord against any liability, cost or expense in connection therewith, including, without limitation, actual attorneys’ fees and costs. Real Property Taxes shall be defined as all actual taxes, assessments, levies, charges and other similar or governmental charges levied or assessed on, imposed upon or attributable to the calendar year in question to the Premises, and/or to t he operation of the Premises, including but not limited to Real Property Taxes against the Premises, personal property taxes or assessments levied or assessed against the Premises, but excluding any tax measured by gross rentals received from the Premises, any net income, franchise, capital stock, succession, transfer, gift, estate or inheritance taxes imposed by the State of California or the United States or by their respective agencies, branches or departments.

22.1 Proration. Tenant’s liability to pay Real Property Taxes shall be prorated on the basis of a 365 day year to account for any fractional portion of a fiscal lax year included at the commencement or expiration of the Term. With respect to any assessments which may be levied against or upon the Premises, or which under the laws then in force may be evidenced by improvements or other bonds or may be paid in annual installments, only the amount of such annual installment (with appropriate portion for any partial year) and interest due thereon shall be included with the computation of the annual Real Property Taxes levied against the Premises.

22.2 Payment on Expiration of Term. If this Lease terminates on a date earlier than the end of a fiscal year, Landlord shall deliver to Tenant a statement setting forth the amount of Real Properly Taxes to be paid by Tenant prorated to the date of termination. Tenant shall pay to Landlord such prorated amount within twenty (20) days of Tenant’s receipt of the statement.

22.3 Personal Property Taxes. Tenant shall pay prior to delinquency all taxes assessed or levied against Tenant’s Personal Property in, on or about the Premises. When possible, Tenant shall cause its Personal Property to be assessed and billed separately from the real or personal property of Landlord. If Tenant shall fail to timely pay such personal property taxes, Landlord shall have the right, but not the obligation, to: (i) pay the same, in which case Tenant shall immediately repay such amount to Landlord including interest at the Interest Rate from the date paid by Landlord until the date of payment by Tenant; and (ii) exercise any and all remedies available to Landlord pursuant to ARTICLE 16.

ARTICLE 23—SURRENDER OF LEASE

The voluntary or other surrender of the Lease by Tenant, or a mutual cancellation of the Lease, shall not work a merger, and shall, at the option of Landlord, terminate all or any existing subleases or subtenancies, or may, at the option of Landlord, operate as an assignment to it, of Tenant’s interest in any or all such subleases or subtenancies.

ARTICLE 24—WAIVER

The waiver by Landlord or Tenant of any term, covenant, agreement or condition contained in this Lease shall not be deemed to be a waiver of any subsequent breach of the same or of any other term, covenant, agreement, condition or provision of this Lease, nor shall any custom or practice which may develop between the parties in the administration of the Lease be construed to waive or lessen the right of Landlord or Tenant to insist upon the performance by the other in strict accordance with all of the terms, covenants, agreements, conditions, and provisions of the Lease. The subsequent acceptance by Landlord of any payment owed by Tenant to Landlord under the Lease, or the payment of Rent by Tenant, shall not be deemed to be a waiver of any preceding breach by Tenant of any term, covenant, agreement, condition or provision of the Lease, other than the failure, of Tenant to make the specific payment so accepted by Landlord, regardless of Landlord’s or Tenant’s knowledge of such preceding breach at the time of the making or acceptance of such payment.

ARTICLE 25—SALE BY LANDLORD

In the event Landlord shall sell, assign, convey or transfer all or a part of its interest in the Building or any part of the Building, Tenant agrees to attain to such transferee, assignee or new owner, and upon consummation of such role, conveyance or transfer, Landlord shall automatically be freed and relieved from all liability and obligations accruing or to be performed from and after the date of such sale, transfer, or conveyance.

ARTICLE 26—NO LIGHT AND AIR EASEMENT

Any diminution or shutting off of light or air by any structure which may be erected on lands adjacent to or in the vicinity of the Building shall not affect the Lease, ▇▇▇▇▇ any payment owed by Tenant under the Lease (except pursuant to ARTICLE 12, ARTICLE 13 and ARTICLE 14 of this Lease) or otherwise impose any liability on Landlord.

ARTICLE 27—FORCE MAJEURE

Any prevention, delay or stoppage caused by fire, earthquake, explosion, flood, hurricane, the elements, or any other similar cause beyond the reasonable control of the party from whom performance is required, or any of their contractors; acts of God or the public enemy; actions, restrictions, limitations or interference of governmental authorities or agents, war, invasion, insurrection, rebellion; riots; strikes or lockouts, or inability to obtain necessary materials, goods, equipment, services, utilities or labor shall excuse the performance of such party for a period equal to the duration of such prevention, delay or stoppage; provided, however, in no event shall financial incapability excuse the performance of either party.

ARTICLE 28—ESTOPPEL CERTIFICATES

Within twenty (20) days after request by Landlord transmitted to Tenant by certified mail, return receipt requested, Tenant shall execute and deliver to Landlord a statement in such form as Landlord may reasonably request, or as a prospective purchaser or encumbrancer of the Premises may reasonably request. Any such statement may be conclusively relied upon by any prospective purchaser or encumbrancer of the Premises or of all or any portion of the Premises. Tenant’s failure to deliver such statement within twenty (20) days of Landlord’s written request therefor shall be a binding agreement of Tenant (i) that this Lease is in full force and effect, without modification except as may be represented by Landlord; (ii) that them are no uncured defaults in Landlord’s performance hereunder; and (iii) that not more than one monthly installment of the Minimum Annual Rent has been paid in advance. Further, such failure to delive r such certificate by Tenant (showing any exceptions to any of the statements of fact required thereby) shall be a material breach of this Lease.

ARTICLE 29—RIGHT TO PERFORMANCE

All covenants and agreements to be performed by Tenant under the Lease shall be performed by Tenant at Tenant’s sole cost and expense. If Tenant shall fail to perform any act on its part to be performed under the Lease, and such failure shall continue for three (3) days after notice thereof to Tenant (provided that no notice shall be required in cases of emergency), Landlord may, but shall not be obligated to do so, without waiving or releasing Tenant from any obligations of Tenant, perform any such act on Tenant’s part to be made or performed as provided in the Lease. All costs incurred by Landlord with respect to any such performance by Landlord (including reasonable attorneys’ fees) shall be immediately paid by Tenant to Landlord.

ARTICLE 30—SECURITY DEPOSIT

Tenant shall deposit with Landlord concurrently with Tenant’s execution of this Lease, the sum of One Million Dollars ($1,000,000.00) as the security deposit (the “ Security Deposit”). The Security Deposit shall be held by Landlord as security for the faithful performance by Tenant of all the provisions of this Lease to be performed or observed by Tenant. If Tenant fails to pay Rent when due, or otherwise defaults with respect to any provision of this Lease, Landlord may use, apply or retain all or any portion of the Security Deposit for the payment of any Rent in default or for the payment of any other sum to which Landlord may become obligated by reason of Tenant’s default, or to compensate Landlord for any loss or damage which Landlord may suffer thereby. If Landlord so uses or applies all or any portion of the Security Deposit, Tenant shall within 10 days after demand therefor deposit cash with Landlord in an am ount sufficient to restore the Security Deposit to the full amount thereof and Tenant’s failure to do so shall be a material breach of this Lease. Landlord shall not be required to keep the Security Deposit separate from its general accounts. As long as there shall not have occurred any default by Tenant in the performance of its obligations under this Lease during the first sixty (60)months of the Lease Term, Landlord shall, on the first (1st) day of the sixty-first (61st)month of the Lease Term (“Reduction Date”) return to Tenant that portion of the Security Deposit such that the remaining Security Deposit then held by Landlord shall be equal to the Base Rent for the last month of the Lease Term, i.e., to $204,952.00 (“Reduced Security Deposit”). The Reduced Security Deposit, or so much thereof as has not theretofore been applied by Landlord, shall be returned, with interest on the Security Deposit and the Reduced Security Deposit at the Interest Rate, to Tenant (or, at Landlord’s option, to the last assignee, if any, of Tenant’s interest hereunder)at the expiration of the term hereof or earlier termination, and after Tenant has vacated the Premises in accordance with the terms of this Lease; provided, however, that upon the occurrence of a default by Tenant under the Lease, interest shall stop accruing on the Security Deposit and the Reduced Security Deposit, as applicable. No trust relationship is created herein between Landlord and Tenant with respect to the Security Deposit.

In lieu of depositing cash with Landlord as the Security Deposit, Tenant may deliver to Landlord concurrent with the execution by Tenant of this Lease, an unconditional, clear, irrevocable letter of credit (“Tenant L-C”) in the initial amount of $1,000,000.00, which Tenant L-C shall be issued by a money-center bank (a bank which has a local San ▇▇▇▇ officer which will negotiate a letter of credit and whose deposits are insured by the FDIC) reasonably acceptable to Landlord, and which Tenant L-C shall be in a form and content reasonably accountable to Landlord. Tenant shall pay all expenses, points and/or fees incurred by Tenant in obtaining the Tenant L-C. Until the reduction Date, the required amount of the Tenant L-C shall remain at $1,000,000.00. As long as there shall not have occurred any default by Tenant in the performance of its obligations under this Lease during the first sixty (60) months of the Lease Term, Tenant shall, on the Reduction Date, deliver to Landlord a Tenant L-C

in the amount of the last month’s Base Rent or $204,957.00. (“Substitute Tenant L-C”), and Landlord shall, pursuant to its receipt of the Substitute Tenant L-C, return to Tenant the original Tenant L-C.

The Tenant L-C shall be held by Landlord as security for the faithful performance by Tenant of all the terms, covenants and conditions of this Lease to be kept and performed by Tenant during the Lease Term. The Tenant L-C shall not be mortgaged, assigned or encumbered in any manner whatsoever by Tenant without the prior written consent of Landlord. If Tenant is in default under the Lease with all applicable cure periods having expired during the Lease Term, Landlord may, but shall not be required to, draw upon all or any portion of the Tenant L-C; for the payment of any amount that Landlord may reasonably spend or may become obligated to spend by reason of such Tenant default, or to compensate Landlord for any other loss or damage that Landlord may suffer by reason of a Tenant default as set forth herein. The use, application or retention of the Tenant L-C, or any portion thereof, by Landlord shall not prevent Landlord from exercising any other right or remedy provided by this Lease or by law, it being intended that Landlord shall not first be required to proceed against the Tenant L-C and shall not operate as a limitation on any recovery to which Landlord may otherwise be entitled. Any amount of the Tenant L-C which is drawn upon by Landlord, but is not used or applied by Landlord, shall be held by Landlord and deemed a security deposit (the “Tenant L-C Security Deposit”). If any portion of the Tenant L-C is drawn upon, Tenant shall, within five (5) days after written demand therefor, either (i) deposit cash with Landlord (which cash shall be applied by Landlord to the Tenant L-C Security Deposit) in an amount sufficient to cause the sum of the Tenant L-C Security Deposit and the amount of the remaining Tenant L-C to be equivalent to the amount of the Tenant L-C then required under this Lease or (ii) reinstate the Tenant L-C to the amount then required under this Lease, and if any portion of the Tenant L-C Security Deposit is used or applied, Tenant shall, within five (5) days after written demand therefor, deposit cash with Landlord (which cash shall be applied by Landlord to the Tenant L-C Security Deposit) in an amount sufficient to restore the Tenant L-C Security Deposit to the amount then required under this Lease.

In the event Tenant shall elect to amortize the Additional Improvement Allowance, as more particularly set forth in Section 6(c) of the Work Letter Agreement, the amount of such Additional Improvement Allowance shall be added to either the Security Deposit or Tenant L-C, as applicable.
