3. Adjustment of Commencement Date; Possession.

3.01 If Landlord is required to perform Landlord Work prior to the Commencement Date: (a) the date set forth in Section 1.06 as the Commencement Date shall instead be defined as the “Target Commencement Date”; (b) the actual Commencement Date shall be the date on which the Landlord Work is Substantially Complete (defined below); and (c) the Termination Date will be the last day of the Term as determined based upon a period of 12 months and 0 days from the actual Commencement Date. Landlord’s failure to Substantially Complete the Landlord Work by the Target Commencement Date shall not be a default by Landlord or otherwise render Landlord liable for damages. Promptly after the determination of the Commencement Date, Landlord and Tenant shall enter into a commencement letter agreement in the form attached as Exhibit D which commencement letter agreement shall be deemed accepted by Tenant if not executed and returned to Landlord by Tenant within 30 days after the date that Landlord delivers the commencement letter agreement to Tenant for execution. If the Termination Date does not fall on the last day of a calendar month, Landlord and Tenant may elect to adjust the Termination Date to the last day of the calendar month in which Termination Date occurs by the mutual execution of a commencement letter agreement setting forth such adjusted date. The Landlord Work shall be deemed to be “Substantially Complete” on the date that all Landlord Work has been performed, other than any details of construction, mechanical adjustment or any other similar matter, the non-completion of which does not materially interfere with Tenant’s use of the Premises. If Landlord is delayed in the performance of the Landlord Work as a result of the acts or omissions of Tenant, the Tenant Related Parties (defined in Section 13) or their respective contractors or vendors, including, without limitation, changes requested by Tenant to approved plans, Tenant’s failure to comply with any of its obligations under this Lease, or the specification of any materials or equipment with long lead times (a “Tenant Delay”), the Landlord Work shall be deemed to be Substantially Complete on the date that Landlord could reasonably have been expected to Substantially Complete the Landlord Work absent any Tenant Delay.

3.02 Subject to Landlord’s obligation, if any, to perform Landlord Work, the Premises are accepted by Tenant in “as is” condition and configuration without any representations or warranties by Landlord. By taking possession of the Premises, Tenant agrees that the Premises are in good order and satisfactory condition. Landlord shall not be liable for a failure to deliver possession of the Premises or any other space due to the holdover or unlawful possession of such space by another party, however Landlord shall use reasonable efforts to obtain possession of the space. The commencement date for the space, in such event, shall be postponed until the date Landlord delivers possession of the Premises to Tenant free from occupancy by any party. If Tenant takes possession of the Premises before the Commencement Date, such possession shall be subject to the terms and conditions of this Lease and Tenant shall pay Rent (defined in Section 4.01) to Landlord for each day of possession before the Commencement Date. However, except for the cost of services requested by Tenant (e.g. freight elevator usage), Tenant shall not be required to pay Rent for any days of possession before the Commencement Date during which Tenant, with the approval of Landlord, is in possession of the Premises for the sole purpose of performing improvements or installing furniture, equipment or other personal property.

4. Rent.

4.01 Tenant shall pay Landlord, without any setoff or deduction, unless expressly set forth in this Lease, all Base Rent and Additional Rent due for the Term (collectively referred to as “Rent”). “Additional Rent” means all sums (exclusive of Base Rent) that Tenant is required to pay Landlord under this Lease. Tenant shall pay and be liable for all rental, sales and use taxes (but excluding income taxes), if any, imposed upon or measured by Rent. Base Rent and recurring monthly charges of Additional Rent shall be due and payable in advance on the first day of each calendar month without notice or demand, provided that the installment of Base Rent for the first full calendar month of the Term, and the first

monthly installment of Additional Rent for Expenses and Taxes, shall be payable upon the execution of this Lease by Tenant. All other items of Rent shall be due and payable by Tenant on or before 30 days after billing by Landlord. Rent shall be made payable to the entity, and sent to the address, Landlord designates and shall be made by good and sufficient check or by other means acceptable to Landlord. Tenant shall pay Landlord an administration fee equal to 5% of all past due Rent, provided that Tenant shall be entitled to a grace period of 5 days for the first 2 late payments of Rent in a calendar year. In addition, past due Rent shall accrue interest at 12% per annum. Landlord’s acceptance of less than the correct amount of Rent shall be considered a payment on account of the earliest Rent due. Rent for any partial month during the Term shall be prorated. No endorsement or statement on a check or letter accompanying payment shall be considered an accord and satisfaction. Tenant’s covenant to pay Rent is independent of every other covenant in this Lease.

4.02 Tenant shall pay Tenant’s Pro Rata Share of Taxes and Expenses in accordance with Exhibit B of this Lease.

5. Compliance with Laws; Use.

The Premises shall be used for the Permitted Use and for no other use whatsoever. Tenant shall comply with all statutes, codes, ordinances, orders, rules and regulations of any municipal or governmental entity whether in effect now or later, including the Americans with Disabilities Act (“Law(s)”), regarding the operation of Tenant’s business and the use, condition, configuration and occupancy of the Premises. In addition, Tenant shall, at its sole cost and expense, promptly comply with any Laws that relate to the “Base Building” (defined below), but only to the extent such obligations are triggered by Tenant’s use of the Premises, other than for general office use, or Alterations or improvements in the Premises performed or requested by Tenant. “Base Building” shall include the structural portions of the Building, the public restrooms and the Building mechanical, electrical and plumbing systems and equipment located in the internal core of the Building on the floor or floors on which the Premises are located. Tenant shall promptly provide Landlord with copies of any notices it receives regarding an alleged violation of Law. Tenant shall comply with the rules and regulations of the Building attached as Exhibit E and such other reasonable rules and regulations adopted by Landlord from time to time, including rules and regulations for the performance of Alterations (defined in Section 9).

6. Security Deposit.

The Security Deposit, if any, shall be delivered to Landlord upon the execution of this Lease by Tenant and held by Landlord without liability for interest (unless required by Law) as security for the performance of Tenant’s obligations. The Security Deposit is not an advance payment of Rent or a measure of damages. Landlord may use all or a portion of the Security Deposit to satisfy past due Rent or to cure any Default (defined in Section 18) by Tenant. If Landlord uses any portion of the Security Deposit, Tenant shall, within 5 days after demand, restore the Security Deposit to its original amount. Landlord shall return any unapplied portion of the Security Deposit to Tenant within 45 days after the later to occur of: (a) determination of the final Rent due from Tenant; or (b) the later to occur of the Termination Date or the date Tenant surrenders the Premises to Landlord in compliance with Section 25. Landlord may assign the Security Deposit to a successor or transferee and, following the assignment, Landlord shall have no further liability for the return of the Security Deposit. Landlord shall not be required to keep the Security Deposit separate from its other accounts. Tenant hereby waives the provisions of Section 1950.7 of the California Civil Code, or any similar or successor Laws now or hereinafter in effect.

7. Building Services.

7.01 Landlord shall furnish Tenant with the following services: (a) water for use in the Base Building lavatories; (b) customary heat and air conditioning in season during Building Service Hours.

7.02 Electricity used by Tenant in the Premises shall be paid for by Tenant through inclusion in Expenses (except as provided for excess usage). Without the consent of Landlord, Tenant’s use of electrical service shall not exceed, either in voltage, rated capacity, use beyond Building Service Hours or overall load, that which Landlord reasonably deems to be standard for the Building. Landlord shall have the right to measure electrical usage by commonly accepted methods. If it is determined that Tenant is using excess electricity, Tenant shall pay Landlord for the cost of such excess electrical usage as Additional Rent.

7.03 Landlord’s failure to furnish, or any interruption, diminishment or termination of services due to the application of Laws, the failure of any equipment, the performance of repairs, improvements or alterations, utility interruptions or the occurrence of an event of Force Majeure (defined in Section 26.03) (collectively a “Service Failure”) shall not render Landlord liable to Tenant, constitute a constructive eviction of Tenant, give rise to an abatement of Rent, nor relieve Tenant from the obligation to fulfill any covenant or agreement. However, if the Premises, or a material portion of the Premises, are made untenantable for a period in excess of 3 consecutive Business Days as a result of a Service Failure that is reasonably within the control of Landlord to correct, then Tenant, as its sole remedy, shall be entitled to receive an abatement of Rent payable hereunder during the period beginning on the 4^th consecutive Business Day of the Service Failure and ending on the day the service has been restored. If the entire Premises have not been rendered untenantable by the Service Failure, the amount of abatement shall be equitably prorated.

8. Leasehold Improvements.

All improvements in and to the Premises, including any Alterations (collectively, “Leasehold Improvements”) shall remain upon the Premises at the end of the Term without compensation to Tenant. Landlord, however, by written notice to Tenant at least 30 days prior to the Termination Date, may require Tenant, at its expense, to remove (a) any Cable (defined in Section 9.01) installed by or for the benefit of Tenant, and (b) any Landlord Work or Alterations that, in Landlord’s reasonable judgment, are of a nature that would require removal and repair costs that are materially in excess of the removal and repair costs associated with standard office improvements (collectively referred to as “Required Removables”). Required Removables shall include, without limitation, internal stairways, raised floors, personal baths and showers, vaults, rolling file systems and structural alterations and modifications. The designated Required Removables shall be removed by Tenant before the Termination Date. Tenant shall repair damage caused by the installation or removal of Required Removables. If Tenant fails to perform its obligations in a timely manner, Landlord may perform such work at Tenant’s expense. Tenant, at the time it requests approval for a proposed Alteration, may request in writing that Landlord advise Tenant whether the Alteration or any portion of the Alteration is a Required Removable. Within 10 days after receipt of Tenant’s request, Landlord shall advise Tenant in writing as to which portions of the Alteration are Required Removables.

9. Repairs and Alterations.

9.01 Tenant shall periodically inspect the Premises to identify any conditions that are dangerous or in need of maintenance or repair. Tenant shall promptly provide Landlord with notice of any such conditions. Tenant shall, at its sole cost and expense, perform all maintenance and repairs to the Premises that are not Landlord’s express responsibility under this Lease, and keep the Premises in good condition and repair, reasonable wear and tear excepted. Tenant’s repair and maintenance obligations include, without limitation, repairs to: (a) floor covering; (b) interior partitions; (c) doors; (d) the interior side of demising walls; (e) electronic, phone and data cabling and related equipment that is installed by or for the exclusive benefit of Tenant (collectively, “Cable”); (f) supplemental air conditioning units, kitchens, including hot water heaters, plumbing, and similar facilities exclusively serving Tenant; and (g) Alterations. To the extent Landlord is not reimbursed by insurance proceeds, Tenant shall reimburse Landlord for the cost of repairing damage to the Building caused by the acts of Tenant, Tenant Related Parties and their respective contractors and vendors. If Tenant fails to make any repairs to the Premises for more than 15 days after notice from Landlord (although notice shall not be required in an emergency), Landlord may make the repairs, and Tenant shall pay the reasonable cost of the repairs, together with an administrative charge in an amount equal to 10% of the cost of the repairs.

9.02 Landlord shall keep and maintain in good repair and working order and perform maintenance upon the: (a) structural elements of the Building; (b) mechanical (including HVAC), electrical, plumbing and fire/life safety systems serving the Building in general; (c) Common Areas; (d) roof of the Building; (e) exterior windows of the Building; and (f) elevators serving the Building.

Tenant hereby waives any and all rights under and benefits of subsection 1 of Section 1932, and Sections 1941 and 1942 of the California Civil Code, or any similar or successor Laws now or hereinafter in effect.

9.03 Tenant shall not make alterations, repairs, additions or improvements or install any Cable (collectively referred to as “Alterations”) without first obtaining the written consent of Landlord in each instance, which consent shall not be unreasonably withheld or delayed. However, Landlord’s consent shall not be required for any Alteration that satisfies all of the following criteria (a “Cosmetic Alteration”): (a) is of a cosmetic nature such as painting, wallpapering, hanging pictures and installing carpeting; (b) is not visible from the exterior of the Premises or Building; (c) will not affect the Base Building; and (d) does not require work to be performed inside the walls or above the ceiling of the Premises. Cosmetic Alterations shall be subject to all the other provisions of this Section 9.03.

amounts reasonably required by Landlord and naming Landlord as an additional insured; and any security for performance in amounts reasonably required by Landlord. Changes to the plans and specifications must also be submitted to Landlord for its approval. Alterations shall be constructed in a good and workmanlike manner using materials of a quality reasonably approved by Landlord. Tenant shall reimburse Landlord for any sums paid by Landlord for third party examination of Tenant’s plans for non-Cosmetic Alterations. Upon completion, Tenant shall furnish “as-built” plans for non-Cosmetic Alterations, completion affidavits and full and final waivers of lien. Landlord’s approval of an Alteration shall not be deemed a representation by Landlord that the Alteration complies with Law.

10. Entry by Landlord.

Landlord may enter the Premises to inspect, show or clean the Premises or to perform or facilitate the performance of repairs, alterations or additions to the Premises or any portion of the Building. Except in emergencies or to provide Building services, Landlord shall provide Tenant with reasonable prior verbal notice of entry and shall use reasonable efforts to minimize any interference with Tenant’s use of the Premises. If reasonably necessary, Landlord may temporarily close all or a portion of the Premises to perform repairs, alterations and additions. However, except in emergencies, Landlord will not close the Premises if the work can reasonably be completed on weekends and after Building Service Hours. Entry by Landlord shall not constitute a constructive eviction or entitle Tenant to an abatement or reduction of Rent.

11. Assignment and Subletting.

11.01 Except in connection with a Permitted Transfer (defined in Section 11.04), Tenant shall not assign, sublease, transfer or encumber any interest in this Lease or allow any third party to use any portion of the Premises (collectively or individually, a “Transfer”) without the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed if Landlord does not exercise its recapture rights under Section 11.02. If the entity which controls the voting shares/rights of Tenant changes at any time, such change of ownership or control shall constitute a Transfer unless Tenant is an entity whose outstanding stock is listed on a recognized securities exchange or if at least 80% of its voting stock is owned by another entity, the voting stock of which is so listed. Tenant hereby waives the provisions of Section 1995.310 of the California Civil Code, or any similar or successor Laws, now or hereinafter in effect, and all other remedies, including, without limitation, any right at law or equity to terminate this Lease, on its own behalf and, to the extent permitted under all applicable Laws, on behalf of the proposed transferee. Any attempted Transfer in violation of this Section is voidable by Landlord. In no event shall any Transfer, including a Permitted Transfer, release or relieve Tenant from any obligation under this Lease.

11.02 Tenant shall provide Landlord with financial statements for the proposed transferee, a fully executed copy of the proposed assignment, sublease or other Transfer documentation and such other information as Landlord may reasonably request. Within 15 Business Days after receipt of the required information and documentation, Landlord shall either: (a) consent to the Transfer by execution of a consent agreement in a form reasonably designated by Landlord; (b) reasonably refuse to consent to the Transfer in writing; or (c) in the event of an assignment of this Lease or subletting of more than 20% of the Rentable Square Footage of the Premises for more than 50% of the remaining Term (excluding unexercised options), recapture the portion of the Premises that Tenant is proposing to Transfer. If Landlord exercises its right to recapture, this Lease shall automatically be amended (or terminated if the entire Premises is being assigned or sublet) to delete the applicable portion of the Premises effective on the proposed effective date of the Transfer. Tenant shall pay Landlord a review fee of $1,500.00 for Landlord’s review of any Permitted Transfer or requested Transfer.

11.03 Tenant shall pay Landlord 50% of all rent and other consideration which Tenant receives as a result of a Transfer that is in excess of the Rent payable to Landlord for the portion of the Premises and Term covered by the Transfer. Tenant shall pay Landlord for Landlord’s share of the excess within 30 days after Tenant’s receipt of the excess. Tenant may deduct from the excess, on a straight-line basis, all reasonable and customary expenses directly incurred by Tenant attributable to the Transfer. If Tenant is in Default, Landlord may require that all sublease payments be made directly to Landlord, in which case Tenant shall receive a credit against Rent in the amount of Tenant’s share of payments received by Landlord.

11.04 Tenant may assign this Lease to a successor to Tenant by purchase, merger, consolidation or reorganization (an “Ownership Change”) or assign this Lease or sublet all or a portion of the Premises to an Affiliate without the consent of Landlord, provided that all of the following conditions are satisfied (a “Permitted Transfer”): (a) Tenant is not in Default; (b) in the event of an Ownership Change, Tenant’s successor shall own substantially all of the assets of Tenant and have a net worth which is at least equal to Tenant’s net worth as of the day prior to the proposed Ownership Change; (c) the Permitted Use does not allow the Premises to be used for retail purposes; and (d) Tenant shall give Landlord written notice at least 15 Business Days prior to the effective date of the Permitted Transfer. Tenant’s notice to Landlord shall include information and documentation evidencing the Permitted Transfer and showing

that each of the above conditions has been satisfied. If requested by Landlord, Tenant’s successor shall sign a commercially reasonable form of assumption agreement. “Affiliate” shall mean an entity controlled by, controlling or under common control with Tenant.

12. Liens.

Tenant shall not permit mechanics’ or other liens to be placed upon the Property, Premises or Tenant’s leasehold interest in connection with any work or service done or purportedly done by or for the benefit of Tenant or its transferees. Tenant shall give Landlord notice at least 15 days prior to the commencement of any work in the Premises to afford Landlord the opportunity, where applicable, to post and record notices of non-responsibility. Tenant, within 10 days of notice from Landlord, shall fully discharge any lien by settlement, by bonding or by insuring over the lien in the manner prescribed by the applicable lien Law. If Tenant fails to do so, Landlord may bond, insure over or otherwise discharge the lien. Tenant shall reimburse Landlord for any amount paid by Landlord, including, without limitation, reasonable attorneys’ fees.

13. Indemnity and Waiver of Claims.

Tenant hereby waives all claims against and releases Landlord and its trustees, members, principals, beneficiaries, partners, officers, directors, employees, Mortgagees (defined in Section 23) and agents (the “Landlord Related Parties”) from all claims for any injury to or death of persons, damage to property or business loss in any manner related to (a) Force Majeure, (b) acts of third parties, (c) the bursting or leaking of any tank, water closet, drain or other pipe, (d) the inadequacy or failure of any security services, personnel or equipment, or (e) any matter not within the reasonable control of Landlord. Notwithstanding the foregoing, except as provided in Article 15 to the contrary, Tenant shall not be required to waive any claims against Landlord (other than for loss or damage to Tenant’s business) where such loss or damage is due to the negligence or willful misconduct of Landlord or any Landlord Related Parties. Nothing herein shall be construed as to diminish the repair and maintenance obligations of Landlord contained elsewhere in this Lease. Except to the extent caused by the negligence or willful misconduct of Landlord or any Landlord Related Parties, Tenant shall indemnify, defend and hold Landlord and Landlord Related Parties harmless against and from all liabilities, obligations, damages, penalties, claims, actions, costs, charges and expenses, including, without limitation, reasonable attorneys’ fees and other professional fees (if and to the extent permitted by Law) (collectively referred to as “Losses”), which may be imposed upon, incurred by or asserted against Landlord or any of the Landlord Related Parties by any third party and arising out of or in connection with any damage or injury occurring in the Premises or any acts or omissions (including violations of Law) of Tenant, the Tenant Related Parties or any of Tenant’s transferees, contractors or licensees. Except to the extent caused by the negligence or willful misconduct of Tenant or any Tenant Related Parties, Landlord shall indemnify, defend and hold Tenant, its trustees, members, principals, beneficiaries, partners, officers, directors, employees and agents (“Tenant Related Parties”) harmless against and from all Losses which may be imposed upon, incurred by or asserted against Tenant or any of the Tenant Related Parties by any third party and arising out of or in connection with the acts or omissions (including violations of Law) of Landlord or the Landlord Related Parties.

All policies of Tenant’s Insurance shall contain endorsements that the insurer(s) shall give Landlord and its designees at least 30 days’ advance written notice of any cancellation, termination, material change or lapse of insurance. Tenant shall provide Landlord with a certificate of insurance evidencing Tenant’s Insurance prior to the earlier to occur of the Commencement Date or the date Tenant is provided with possession of the Premises, and thereafter as necessary to assure that Landlord always has current certificates evidencing Tenant’s Insurance. So long as the same is available at commercially reasonable rates, Landlord shall maintain so called All Risk property insurance on the Building at replacement cost value as reasonably estimated by Landlord.

15. Subrogation.

Landlord and Tenant hereby waive and shall cause their respective insurance carriers to waive any and all rights of recovery, claims, actions or causes of action against the other for any loss or damage with respect to Tenant’s Property, Leasehold Improvements, the Building, the Premises, or any contents thereof, including rights, claims, actions and causes of action based on negligence, which loss or damage is (or would have been, had the insurance required by this Lease been carried) covered by insurance.

16. Casualty Damage.

16.01 If all or any portion of the Premises becomes untenantable by fire or other casualty to the Premises (collectively a “Casualty”), Landlord, with reasonable promptness, shall cause a general contractor selected by Landlord to provide Landlord and Tenant with a written estimate of the amount of time required using standard working methods to Substantially Complete the repair and restoration of the Premises and any Common Areas necessary to provide access to the Premises (“Completion Estimate”). If the Completion Estimate indicates that the Premises or any Common Areas necessary to provide access to the Premises cannot be made tenantable within 180 days from the date the repair is started, then either party shall have the right to terminate this Lease upon written notice to the other within 10 days after receipt of the Completion Estimate. Tenant, however, shall not have the right to terminate this Lease if the Casualty was caused by the negligence or intentional misconduct of Tenant or any Tenant Related Parties. In addition, Landlord, by notice to Tenant within 90 days after the date of the Casualty, shall have the right to terminate this Lease if: (1) the Premises have been materially damaged and there is less than 2 years of the Term remaining on the date of the Casualty; (2) any Mortgagee requires that the insurance proceeds be applied to the payment of the mortgage debt; or (3) a material uninsured loss to the Building occurs.

16.02 If this Lease is not terminated, Landlord shall promptly and diligently, subject to reasonable delays for insurance adjustment or other matters beyond Landlord’s reasonable control, restore the Premises and Common Areas. Such restoration shall be to substantially the same condition that existed prior to the Casualty, except for modifications required by Law or any other modifications to the Common Areas deemed desirable by Landlord. Upon notice from Landlord, Tenant shall assign to Landlord (or to any party designated by Landlord) all property insurance proceeds payable to Tenant under Tenant’s Insurance with respect to any Leasehold Improvements performed by or for the benefit of Tenant; provided if the estimated cost to repair such Leasehold Improvements exceeds the amount of insurance proceeds received by Landlord from Tenant’s insurance carrier, the excess cost of such repairs shall be paid by Tenant to Landlord prior to Landlord’s commencement of repairs. Within 15 days of demand, Tenant shall also pay Landlord for any additional excess costs that are determined during the performance of the repairs. Landlord shall not be liable for any inconvenience to Tenant, or injury to Tenant’s business resulting in any way from the Casualty or the repair thereof. Provided that Tenant is not in Default, during any period of time that all or a material portion of the Premises is rendered untenantable as a result of a Casualty, the Rent shall abate for the portion of the Premises that is untenantable and not used by Tenant.

16.03 The provisions of this Lease, including this Section 16, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises or the Property, and any Laws, including, without limitation, Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or obligations concerning damage or destruction in the absence of an express agreement between the parties, and any similar or successor Laws now or hereinafter in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises or the Property.

17. Condemnation.

Either party may terminate this Lease if any material part of the Premises is taken or condemned for any public or quasi-public use under Law, by eminent domain or private purchase in lieu thereof (a “Taking”). Landlord shall also have the right to terminate this Lease if there is a Taking of any portion of the Building or Property which would have a material adverse effect on Landlord’s ability to profitably operate the remainder of the Building. The terminating party shall provide written notice of termination to the other party within 45 days after it first receives notice of the Taking. The termination shall be effective on the date the physical taking occurs. If this Lease is not terminated, Base Rent and Tenant’s Pro Rata Share shall be appropriately adjusted to account for any reduction in the square footage of the Building or Premises. All compensation awarded for a Taking shall be the property of Landlord. The

right to receive compensation or proceeds are expressly waived by Tenant, however, Tenant may file a separate claim for Tenant’s Property and Tenant’s reasonable relocation expenses, provided the filing of the claim does not diminish the amount of Landlord’s award. If only a part of the Premises is subject to a Taking and this Lease is not terminated, Landlord, with reasonable diligence, will restore the remaining portion of the Premises as nearly as practicable to the condition immediately prior to the Taking. Tenant hereby waives any and all rights it might otherwise have pursuant to Section 1265.130 of the California Code of Civil Procedure, or any similar or successor Laws.

18. Events of Default.

Each of the following occurrences shall be a “Default”: (a) Tenant’s failure to pay any portion of Rent when due, if the failure continues for 3 days after written notice to Tenant (“Monetary Default”); (b) Tenant’s failure (other than a Monetary Default) to comply with any term, provision, condition or covenant of this Lease, if the failure is not cured within 10 days after written notice to Tenant provided, however, if Tenant’s failure to comply cannot reasonably be cured within 10 days, Tenant shall be allowed additional time (not to exceed 60 days) as is reasonably necessary to cure the failure so long as Tenant begins the cure within 10 days and diligently pursues the cure to completion; (c) Tenant or any Guarantor becomes insolvent, makes a transfer in fraud of creditors, makes an assignment for the benefit of creditors, admits in writing its inability to pay its debts when due or forfeits or loses its right to conduct business; (d) the leasehold estate is taken by process or operation of Law; (e) in the case of any ground floor or retail Tenant, Tenant does not take possession of or abandons or vacates all or any portion of the Premises; or (f) Tenant is in default beyond any notice and cure period under any other lease or agreement with Landlord at the Building or Property. If Landlord provides Tenant with notice of Tenant’s failure to comply with any specific provision of this Lease on 3 separate occasions during any 12 month period, Tenant’s subsequent violation of such provision shall, at Landlord’s option, be an incurable Default by Tenant. All notices sent under this Section shall be in satisfaction of, and not in addition to, notice required by Law.

19. Remedies.

19.01 Upon the occurrence of any Default under this Lease, whether enumerated in Section 18 or not, Landlord shall have the option to pursue any one or more of the following remedies without any notice (except as expressly prescribed herein) or demand whatsoever (and without limiting the generality of the foregoing, Tenant hereby specifically waives notice and demand for payment of Rent or other obligations, except for those notices specifically required pursuant to the terms of Section 18 or this Section 19, and waives any and all other notices or demand requirements imposed by applicable law):

(a) Terminate this Lease and Tenant’s right to possession of the Premises and recover from Tenant an award of damages equal to the sum of the following:

(i) The Worth at the Time of Award of the unpaid Rent which had been earned at the time of termination;

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

(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 Rent loss that Tenant affirmatively proves could be reasonably avoided;

(iv) Any other amount necessary to compensate Landlord for all the detriment either proximately caused by Tenant’s failure to perform Tenant’s obligations under this Lease or which in the ordinary course of things would be likely to result therefrom; and

(v) All such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time under applicable law.

The “Worth at the Time of Award” of the amounts referred to in parts (i) and (ii) above, shall be computed by allowing interest at the lesser of a per annum rate equal to: (A) the greatest per annum rate of interest permitted from time to time under applicable law, or (B) the Prime Rate plus 5%. For purposes hereof, the “Prime Rate” shall be the per annum interest rate publicly announced as its prime or base rate by a federally insured bank selected by Landlord in the State of California. The “Worth at the Time of Award” of the amount referred to in part (iii), above, 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 1%;

(b) Employ the remedy described in California Civil Code § 1951.4 (Landlord may continue this Lease in effect after Tenant’s breach and abandonment and recover Rent as it becomes due, if Tenant has the right to sublet or assign, subject only to reasonable limitations); or

(c) Notwithstanding Landlord’s exercise of the remedy described in California Civil Code § 1951.4 in respect of an event or events of default, at such time thereafter as Landlord may elect in writing, to terminate this Lease and Tenant’s right to possession of the Premises and recover an award of damages as provided above in Paragraph 19.01(a).

19.02 The subsequent acceptance of Rent hereunder by Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of any term, covenant or condition of this Lease, other than the failure of Tenant to pay the particular Rent so accepted, regardless of Landlord’s knowledge of such preceding breach at the time of acceptance of such Rent. No waiver by Landlord of any breach hereof shall be effective unless such waiver is in writing and signed by Landlord.

19.03 TENANT HEREBY WAIVES ANY AND ALL RIGHTS CONFERRED BY SECTION 3275 OF THE CIVIL CODE OF CALIFORNIA AND BY SECTIONS 1174 (c) AND 1179 OF THE CODE OF CIVIL PROCEDURE OF CALIFORNIA AND ANY AND ALL OTHER LAWS AND RULES OF LAW FROM TIME TO TIME IN EFFECT DURING THE LEASE TERM PROVIDING THAT TENANT SHALL HAVE ANY RIGHT TO REDEEM, REINSTATE OR RESTORE THIS LEASE FOLLOWING ITS TERMINATION BY REASON OF TENANT’S BREACH. TENANT ALSO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, THE RIGHT TO TRIAL BY JURY IN ANY LITIGATION ARISING OUT OF OR RELATING TO THIS LEASE.

19.04 No right or remedy herein conferred upon or reserved to Landlord is intended to be exclusive of any other right or remedy, and each and every right and remedy shall be cumulative and in addition to any other right or remedy given hereunder or now or hereafter existing by agreement, applicable law or in equity. In addition to other remedies provided in this Lease, Landlord shall be entitled, to the extent permitted by applicable law, to injunctive relief, or to a decree compelling performance of any of the covenants, agreements, conditions or provisions of this Lease, or to any other remedy allowed to Landlord at law or in equity. Forbearance by Landlord to enforce 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.

19.05 If Tenant is in Default of any of its non-monetary obligations under the Lease, Landlord shall have the right to perform such obligations. Tenant shall reimburse Landlord for the cost of such performance upon demand together with an administrative charge equal to 10% of the cost of the work performed by Landlord.

19.06 This Section 19 shall be enforceable to the maximum extent such enforcement is not prohibited by applicable law, and the unenforceability of any portion thereof shall not thereby render unenforceable any other portion.

20. Limitation of Liability.

NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS LEASE, THE LIABILITY OF LANDLORD (AND OF ANY SUCCESSOR LANDLORD) SHALL BE LIMITED TO THE LESSER OF (A) THE INTEREST OF LANDLORD IN THE PROPERTY, OR (B) THE EQUITY INTEREST LANDLORD WOULD HAVE IN THE PROPERTY IF THE PROPERTY WERE ENCUMBERED BY THIRD PARTY DEBT IN AN AMOUNT EQUAL TO 70% OF THE VALUE OF THE PROPERTY. TENANT SHALL LOOK SOLELY TO LANDLORD’S INTEREST IN THE PROPERTY FOR THE RECOVERY OF ANY JUDGMENT OR AWARD AGAINST LANDLORD OR ANY LANDLORD RELATED PARTY. NEITHER LANDLORD NOR ANY LANDLORD RELATED PARTY SHALL BE PERSONALLY LIABLE FOR ANY JUDGMENT OR DEFICIENCY, AND IN NO EVENT SHALL LANDLORD OR ANY LANDLORD RELATED PARTY BE LIABLE TO TENANT FOR ANY LOST PROFIT, DAMAGE TO OR LOSS OF BUSINESS OR ANY FORM OF SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGE. BEFORE FILING SUIT FOR AN ALLEGED DEFAULT BY LANDLORD, TENANT SHALL GIVE LANDLORD AND THE MORTGAGEE(S) WHOM TENANT HAS BEEN NOTIFIED HOLD MORTGAGES (DEFINED IN SECTION 23 BELOW), NOTICE AND REASONABLE TIME TO CURE THE ALLEGED DEFAULT.

21. Relocation. Intentionally Omitted.

22. Holding Over.

If Tenant fails to surrender all or any part of the Premises at the termination of this Lease, occupancy of the Premises after termination shall be that of a tenancy at sufferance. Tenant’s occupancy shall be subject to all the terms and provisions of this Lease, and Tenant shall pay an amount (on a per month basis without reduction for partial months during the holdover) equal to 150% of the sum of the Base Rent and Additional Rent due for the period immediately preceding the holdover. No holdover by Tenant or payment by Tenant after the termination of this Lease shall be construed to extend the Term or prevent Landlord from immediate recovery of possession of the Premises by summary proceedings or otherwise. If Landlord is unable to deliver possession of the Premises to a new tenant or to perform improvements for a new tenant as a result of Tenant’s holdover and Tenant fails to vacate the Premises within 15 days after notice from Landlord, Tenant shall be liable for all damages that Landlord suffers from the holdover.

23. Subordination to Mortgages; Estoppel Certificate.

Tenant accepts this Lease subject and subordinate to any mortgage(s), deed(s) of trust, ground lease(s) or other lien(s) now or subsequently arising upon the Premises, the Building or the Property, and to renewals, modifications, refinancings and extensions thereof (collectively referred to as a “Mortgage”). The party having the benefit of a Mortgage shall be referred to as a “Mortgagee”. This clause shall be self-operative, but upon request from a Mortgagee, Tenant shall execute a commercially reasonable subordination agreement in favor of the Mortgagee. As an alternative, a Mortgagee shall have the right at any time to subordinate its Mortgage to this Lease. Upon request, Tenant, without charge, shall attorn to any successor to Landlord’s interest in this Lease. Landlord and Tenant shall each, within 10 days after receipt of a written request from the other, execute and deliver a commercially reasonable estoppel certificate to those parties as are reasonably requested by the other (including a Mortgagee or prospective purchaser). Without limitation, such estoppel certificate may include a certification as to the status of this Lease, the existence of any defaults and the amount of Rent that is due and payable.

24. Notice.

All demands, approvals, consents or notices (collectively referred to as a “notice”) shall be in writing and delivered by hand or sent by registered or certified mail with return receipt requested or sent by overnight or same day courier service at the party’s respective Notice Address(es) set forth in Section 1. Each notice shall be deemed to have been received on the earlier to occur of actual delivery or the date on which delivery is refused, or, if Tenant has vacated the Premises or any other Notice Address of Tenant without providing a new Notice Address, 3 days after notice is deposited in the U.S. mail or with a courier service in the manner described above. Either party may, at any time, change its Notice Address (other than to a post office box address) by giving the other party written notice of the new address.

25. Surrender of Premises.

At the termination of this Lease or Tenant’s right of possession, Tenant shall remove Tenant’s Property from the Premises, and quit and surrender the Premises to Landlord, broom clean, and in good order, condition and repair, ordinary wear and tear and damage which Landlord is obligated to repair hereunder excepted. If Tenant fails to remove any of Tenant’s Property within 2 days after termination of this Lease or Tenant’s right to possession, Landlord, at Tenant’s sole cost and expense, shall be entitled (but not obligated) to remove and store Tenant’s Property. Landlord shall not be responsible for the value, preservation or safekeeping of Tenant’s Property. Tenant shall pay Landlord, upon demand, the expenses and storage charges incurred. If Tenant fails to remove Tenant’s Property from the Premises or storage, within 30 days after notice, Landlord may deem all or any part of Tenant’s Property to be abandoned and title to Tenant’s Property shall vest in Landlord.

26. Miscellaneous.

26.01 This Lease shall be interpreted and enforced in accordance with the Laws of the State of California and Landlord and Tenant hereby irrevocably consent to the jurisdiction and proper venue of such state or commonwealth. If any term or provision of this Lease shall to any extent be void or unenforceable, the remainder of this Lease shall not be affected. If there is more than one Tenant or if Tenant is comprised of more than one party or entity, the obligations imposed upon Tenant shall be joint and several obligations of all the parties and entities, and requests or demands from any one person or entity comprising Tenant shall be deemed to have been made by all such persons or entities. Notices to any one person or entity shall be deemed to have been given to all persons and entities. Tenant represents and warrants to Landlord that each individual executing this Lease on behalf of Tenant is authorized to do so on behalf of Tenant and that Tenant is not, and the entities or individuals constituting Tenant or which may own or control Tenant or which may be owned or controlled by Tenant are not, among the individuals or entities identified on any list compiled pursuant to Executive Order 13224 for the purpose of identifying suspected terrorists.

26.02 If either party institutes a suit against the other for violation of or to enforce any covenant, term or condition of this Lease, the prevailing party shall be entitled to all of its costs and expenses, including, without limitation, reasonable attorneys’ fees. Landlord and Tenant hereby waive any right to trial by jury in any proceeding based upon a breach of this Lease. Either party’s failure to declare a default immediately upon its occurrence, or delay in taking action for a default, shall not constitute a waiver of the default, nor shall it constitute an estoppel.

26.03 Whenever a period of time is prescribed for the taking of an action by Landlord or Tenant (other than the payment of the Security Deposit or Rent), the period of time for the performance of such action shall be extended by the number of days that the performance is actually delayed due to strikes, acts of God, shortages of labor or materials, war, terrorist acts, civil disturbances and other causes beyond the reasonable control of the performing party (“Force Majeure”).

26.04 Landlord shall have the right to transfer and assign, in whole or in part, all of its rights and obligations under this Lease and in the Building and Property. Upon transfer Landlord shall be released from any further obligations hereunder and Tenant agrees to look solely to the successor in interest of Landlord for the performance of such obligations, provided that, any successor pursuant to a voluntary, third party transfer (but not as part of an involuntary transfer resulting from a foreclosure or deed in lieu thereof) shall have assumed Landlord’s obligations under this Lease.

26.05 Landlord has delivered a copy of this Lease to Tenant for Tenant’s review only and the delivery of it does not constitute an offer to Tenant or an option. Tenant represents that it has dealt directly with and only with the Broker as a broker in connection with this Lease. Tenant shall indemnify and hold Landlord and the Landlord Related Parties harmless from all claims of any other brokers claiming to have represented Tenant in connection with this Lease. Landlord shall indemnify and hold Tenant and the Tenant Related Parties harmless from all claims of any brokers claiming to have represented Landlord in connection with this Lease. Equity Office Properties Management Corp. (“EOPMC”) is an affiliate of Landlord and represents only the Landlord in this transaction. Any assistance rendered by any agent or employee of EOPMC in connection with this Lease or any subsequent amendment or modification hereto has been or will be made as an accommodation to Tenant solely in furtherance of consummating the transaction on behalf of Landlord, and not as agent for Tenant.

26.06 Time is of the essence with respect to Tenant’s exercise of any expansion, renewal or extension rights granted to Tenant. The expiration of the Term, whether by lapse of time, termination or otherwise, shall not relieve either party of any obligations which accrued prior to or which may continue to accrue after the expiration or termination of this Lease.

26.07 Tenant may peacefully have, hold and enjoy the Premises, subject to the terms of this Lease, provided Tenant pays the Rent and fully performs all of its covenants and agreements. This covenant shall be binding upon Landlord and its successors only during its or their respective periods of ownership of the Building.

26.08 This Lease does not grant any rights to light or air over or about the Building. Landlord excepts and reserves exclusively to itself any and all rights not specifically granted to Tenant under this Lease. This Lease constitutes the entire agreement between the parties and supersedes all prior agreements and understandings related to the Premises, including all lease proposals, letters of intent and other documents. Neither party is relying upon any warranty, statement or representation not contained in this Lease. This Lease may be modified only by a written agreement signed by an authorized representative of Landlord and Tenant.

OUTLINE AND LOCATION OF PREMISES

This Exhibit is attached to and made a part of the Lease by and between CA-ONE BAY PLAZA LIMITED PARTNERSHIP, a Delaware limited partnership (“Landlord”) and Opta Corporation, a Delaware corporation (“Tenant”) for space in the Building located at 1350 Old Bayshore Highway, Burlingame, California, commonly known as One Bay Plaza.

EXHIBIT B

EXPENSES AND TAXES

1. Payments.

1.01 Tenant shall pay Tenant’s Pro Rata Share of the amount, if any, by which Expenses (defined below) for each calendar year during the Term exceed Expenses for the Base Year (the “Expense Excess”) and also the amount, if any, by which Taxes (defined below) for each calendar year during the Term exceed Taxes for the Base Year (the “Tax Excess”). If Expenses or Taxes in any calendar year decrease below the amount of Expenses or Taxes for the Base Year, Tenant’s Pro Rata Share of Expenses or Taxes, as the case may be, for that calendar year shall be $0. Landlord shall provide Tenant with a good faith estimate of the Expense Excess and of the Tax Excess for each calendar year during the Term. On or before the first day of each month, Tenant shall pay to Landlord a monthly installment equal to one-twelfth of Tenant’s Pro Rata Share of Landlord’s estimate of both the Expense Excess and Tax Excess. After its receipt of the revised estimate, Tenant’s monthly payments shall be based upon the revised estimate. If Landlord does not provide Tenant with an estimate of the Expense Excess or the Tax Excess by January 1 of a calendar year, Tenant shall continue to pay monthly installments based on the previous year’s estimate(s) until Landlord provides Tenant with the new estimate.

1.02 As soon as is practical following the end of each calendar year, Landlord shall furnish Tenant with a statement of the actual Expenses and Expense Excess and the actual Taxes and Tax Excess for the prior calendar year. If the estimated Expense Excess or estimated Tax Excess for the prior calendar year is more than the actual Expense Excess or actual Tax Excess, as the case may be, for the prior calendar year, Landlord shall either provide Tenant with a refund or apply any overpayment by Tenant against Additional Rent due or next becoming due, provided if the Term expires before the determination of the overpayment, Landlord shall refund any overpayment to Tenant after first deducting the amount of Rent due. If the estimated Expense Excess or estimated Tax Excess for the prior calendar year is less than the actual Expense Excess or actual Tax Excess, as the case may be, for such prior year, Tenant shall pay Landlord, within 30 days after its receipt of the statement of Expenses or Taxes, any underpayment for the prior calendar year.

2. Expenses.

2.01 “Expenses” means all costs and expenses incurred in each calendar year in connection with operating, maintaining, repairing, and managing the Building and the Property. Expenses include, without limitation: (a) all labor and labor related costs, including wages, salaries, bonuses, taxes, insurance, uniforms, training, retirement plans, pension plans and other employee benefits; (b) management fees; (c) the cost of equipping, staffing and operating an on-site and/or off-site management office for the Building, provided if the management office services one or more other buildings or properties, the shared costs and expenses of equipping, staffing and operating such management office(s) shall be equitably prorated and apportioned between the Building and the other buildings or properties; (d) accounting costs; (e) the cost of services; (f) rental and purchase cost of parts, supplies, tools and equipment; (g) insurance premiums and deductibles; (h) electricity, gas and other utility costs; and (i) the amortized cost of capital improvements (as distinguished from replacement parts or components installed in the ordinary course of business) made subsequent to the Base Year which are: (1) performed primarily to reduce current or future operating expense costs, upgrade Building security or otherwise improve the operating efficiency of the Property; or (2) required to comply with any Laws that are enacted, or first interpreted to apply to the Property, after the date of this Lease. The cost of capital improvements shall be amortized by Landlord over the lesser of the Payback Period (defined below) or the useful life of the capital improvement as reasonably determined by Landlord. The amortized cost of capital improvements may, at Landlord’s option, include actual or imputed interest at the rate that Landlord would reasonably be required to pay to finance the cost of the capital improvement. “Payback Period” means the reasonably estimated period of time that it takes for the cost savings resulting from a capital improvement to equal the total cost of the capital improvement. Landlord, by itself or through an affiliate, shall have the right to directly perform, provide and be compensated for any services under this Lease. If Landlord incurs Expenses for the Building or Property together with one or more other buildings or properties, whether pursuant to a reciprocal easement agreement, common area agreement or otherwise, the shared costs and expenses shall be equitably prorated and apportioned between the Building and Property and the other buildings or properties.

2.02 Expenses shall not include: the cost of capital improvements (except as set forth above); depreciation; principal payments of mortgage and other non-operating debts of Landlord; the cost of

repairs or other work to the extent Landlord is reimbursed by insurance or condemnation proceeds; costs in connection with leasing space in the Building, including brokerage commissions; lease concessions, rental abatements and construction allowances granted to specific tenants; costs incurred in connection with the sale, financing or refinancing of the Building; fines, interest and penalties incurred due to the late payment of Taxes or Expenses; organizational expenses associated with the creation and operation of the entity which constitutes Landlord; or any penalties or damages that Landlord pays to Tenant under this Lease or to other tenants in the Building under their respective leases.

2.03 If at any time during a calendar year the Building is not at least 95% occupied or Landlord is not supplying services to at least 95% of the total Rentable Square Footage of the Building, Expenses shall, at Landlord’s option, be determined as if the Building had been 95% occupied and Landlord had been supplying services to 95% of the Rentable Square Footage of the Building. If Expenses for a calendar year are determined as provided in the prior sentence, Expenses for the Base Year shall also be determined in such manner. Notwithstanding the foregoing, Landlord may calculate the extrapolation of Expenses under this Section based on 100% occupancy and service so long as such percentage is used consistently for each year of the Term. The extrapolation of Expenses under this Section shall be performed in accordance with the methodology specified by the Building Owners and Managers Association.

3. “Taxes” shall mean: (a) all real property taxes and other assessments on the Building and/or Property, including, but not limited to, gross receipts taxes, assessments for special improvement districts and building improvement districts, governmental charges, fees and assessments for police, fire, traffic mitigation or other governmental service of purported benefit to the Property, taxes and assessments levied in substitution or supplementation in whole or in part of any such taxes and assessments and the Property’s share of any real estate taxes and assessments under any reciprocal easement agreement, common area agreement or similar agreement as to the Property; (b) all personal property taxes for property that is owned by Landlord and used in connection with the operation, maintenance and repair of the Property; and (c) all costs and fees incurred in connection with seeking reductions in any tax liabilities described in (a) and (b), including, without limitation, any costs incurred by Landlord for compliance, review and appeal of tax liabilities. Without limitation, Taxes shall not include any income, capital levy, transfer, capital stock, gift, estate or inheritance tax. If a change in Taxes is obtained for any year of the Term during which Tenant paid Tenant’s Pro Rata Share of any Tax Excess, then Taxes for that year will be retroactively adjusted and Landlord shall provide Tenant with a credit, if any, based on the adjustment. Likewise, if a change is obtained for Taxes for the Base Year, Taxes for the Base Year shall be restated and the Tax Excess for all subsequent years shall be recomputed. Tenant shall pay Landlord the amount of Tenant’s Pro Rata Share of any such increase in the Tax Excess within 30 days after Tenant’s receipt of a statement from Landlord.

4. Audit Rights. Tenant, within 365 days after receiving Landlord’s statement of Expenses, may give Landlord written notice (“Review Notice”) that Tenant intends to review Landlord’s records of the Expenses for the calendar year to which the statement applies. Within a reasonable time after receipt of the Review Notice, Landlord shall make all pertinent records available for inspection that are reasonably necessary for Tenant to conduct its review. If any records are maintained at a location other than the management office for the Building, Tenant may either inspect the records at such other location or pay for the reasonable cost of copying and shipping the records. If Tenant retains an agent to review Landlord’s records, the agent must be with a CPA firm licensed to do business in the state or commonwealth where the Property is located. Tenant shall be solely responsible for all costs, expenses and fees incurred for the audit. Within 90 days after the records are made available to Tenant, Tenant shall have the right to give Landlord written notice (an “Objection Notice”) stating in reasonable detail any objection to Landlord’s statement of Expenses for that year. If Tenant fails to give Landlord an Objection Notice within the 90 day period or fails to provide Landlord with a Review Notice within the 365 day period described above, Tenant shall be deemed to have approved Landlord’s statement of Expenses and shall be barred from raising any claims regarding the Expenses for that year. The records obtained by Tenant shall be treated as confidential. In no event shall Tenant be permitted to examine Landlord’s records or to dispute any statement of Expenses unless Tenant has paid and continues to pay all Rent when due.

3. Landlord’s supervision or performance of any work for or on behalf of Tenant shall not be deemed to be a representation by Landlord that such work complies with applicable insurance requirements, building codes, ordinances, laws or regulations or that the improvements constructed will be adequate for Tenant’s use.

4. This Exhibit shall not be deemed applicable to any additional space added to the Premises at any time or from time to time, whether by any options under the Lease or otherwise, or to any portion of the original Premises or any additions to the Premises in the event of a renewal or extension of the original Term of the Lease, whether by any options under the Lease or otherwise, unless expressly so provided in the Lease or any amendment or supplement to the Lease.

Tenant shall not, without Landlord’s prior written consent, use, store, install, spill, remove, release or dispose of, within or about the Premises or any other portion of the Property, any asbestos-containing materials or any solid, liquid or gaseous material now or subsequently considered toxic or hazardous under the provisions of 42 U.S.C. Section 9601 et seq. or any other applicable environmental Law which may now or later be in effect. Tenant shall comply with all Laws pertaining to and governing the use of these materials by Tenant and shall remain solely liable for the costs of abatement and removal.

13. Tenant shall not use or occupy the Premises in any manner or for any purpose which might injure the reputation or impair the present or future value of the Premises or the Building. Tenant shall not use, or permit any part of the Premises to be used for lodging, sleeping or for any illegal purpose.

Tenant shall not take any action which would violate Landlord’s labor contracts or which would cause a work stoppage, picketing, labor disruption or dispute or interfere with Landlord’s or any other tenant’s or occupant’s business or with the rights and privileges of any person lawfully in the Building (“Labor Disruption”). Tenant shall take the actions necessary to resolve the Labor Disruption, and shall have pickets removed and, at the request of Landlord, immediately terminate any work in the Premises that gave rise to the Labor Disruption, until Landlord gives its written consent for the work to resume. Tenant shall have no claim for damages against Landlord or any of the Landlord Related Parties nor shall the Commencement Date of the Term be extended as a result of the above actions.

Tenant shall not install, operate or maintain in the Premises or in any other area of the Building, electrical equipment that would overload the electrical system beyond its capacity for proper, efficient and safe operation as determined solely by Landlord. Tenant shall not furnish cooling or heating to the Premises, including, without limitation, the use of electric or gas heating devices, without Landlord’s prior written consent. Tenant shall not use more than its proportionate share of telephone lines and other telecommunication facilities available to service the Building.

16. Tenant shall not operate or permit to be operated a coin or token operated vending machine or similar device (including, without limitation, telephones, lockers, toilets, scales, amusement devices and machines for sale of beverages, foods, candy, cigarettes and other goods), except for machines for the exclusive use of Tenant’s employees and invitees.

19. Landlord shall have the right to prohibit the use of the name of the Building or any other publicity by Tenant that in Landlord’s sole opinion may impair the reputation of the Building or its desirability. Upon written notice from Landlord, Tenant shall refrain from and discontinue such publicity immediately.

20. Neither Tenant nor its agents, employees, contractors, guests or invitees shall smoke or permit smoking in the Common Areas, unless a portion of the Common Areas have been declared a designated smoking area by Landlord, nor shall the above parties allow smoke from the Premises to emanate into the Common Areas or any other part of the Building. Landlord shall have the right to designate the Building (including the Premises) as a non-smoking building.

21. Landlord shall have the right to designate and approve standard window coverings for the Premises and to establish rules to assure that the Building presents a uniform exterior

appearance. Tenant shall ensure, to the extent reasonably practicable, that window coverings are closed on windows in the Premises while they are exposed to the direct rays of the sun.

22. Deliveries to and from the Premises shall be made only at the times in the areas and through the entrances and exits reasonably designated by Landlord. Tenant shall not make deliveries to or from the Premises in a manner that might interfere with the use by any other tenant of its premises or of the Common Areas, any pedestrian use, or any use which is inconsistent with good business practice.

23. The work of cleaning personnel shall not be hindered by Tenant after 5:30 P.M., and cleaning work may be done at any time when the offices are vacant. Windows, doors and fixtures may be cleaned at any time. Tenant shall provide adequate waste and rubbish receptacles to prevent unreasonable hardship to the cleaning service.

EXHIBIT F

ADDITIONAL PROVISIONS

1. Asbestos Notification. Tenant acknowledges that Tenant has received the asbestos notification letter attached to this Lease as Exhibit H hereto, disclosing the existence of asbestos in the Building. As part of Tenant’s obligations under this Lease, Tenant agrees to comply with the California “Connelly Act” and other applicable Laws, including providing copies of Landlord’s asbestos notification letter to all of Tenant’s “employees” and “owners”, as those terms are defined in the Connelly Act and other applicable Laws.

2. Renewal Option.

A. Grant of Option; Conditions. Tenant shall have the right to extend the Term (the “Renewal Option”) for one additional period of 1 year commencing on the day following the Termination Date of the initial Term and ending on the 1st anniversary of the Termination Date (the “Renewal Term”), if:

1. Landlord receives notice of exercise (“Initial Renewal Notice”) not less than 94 full calendar months prior to the expiration of the initial Term and not more than 126 full calendar months prior to the expiration of the initial Term; and

2. Tenant is not in default under the Lease beyond any applicable cure periods at the time that Tenant delivers its Initial Renewal Notice or at the time Tenant delivers its Binding Notice (as defined below); and

3. No part of the Premises is sublet (other than pursuant to a Permitted Transfer, as defined in Section 11 of the Lease) at the time that Tenant delivers its Initial Renewal Notice or at the time Tenant delivers its Binding Notice; and

4. The Lease has not been assigned (other than pursuant to a Permitted Transfer, as defined in Section 11 of the Lease) prior to the date that Tenant delivers its Initial Renewal Notice or prior to the date Tenant delivers its Binding Notice.

B. Terms Applicable to Premises During Renewal Term.

1. The initial Base Rent rate per rentable square foot for the Premises during the Renewal Term shall equal the Prevailing Market (hereinafter defined) rate per rentable square foot for the Premises. Base Rent during the Renewal Term shall increase, if at all, in accordance with the increases assumed in the determination of Prevailing Market rate. Base Rent attributable to the Premises shall be payable in monthly installments in accordance with the terms and conditions of Section 4 of the Lease.

2. Tenant shall pay Additional Rent (i.e. Taxes and Expenses) for the Premises during the Renewal Term in accordance with Section 4 of the Lease, and the manner and method in which Tenant reimburses Landlord for Tenant’s share of Taxes and Expenses and the Base Year, if any, applicable to such matter, shall be some of the factors considered in determining the Prevailing Market rate for the Renewal Term.

C. Procedure for Determining Prevailing Market. Within 30 days after receipt of Tenant’s Initial Renewal Notice, Landlord shall advise Tenant of the applicable Base Rent rate for the Premises for the Renewal Term. Tenant, within 15 days after the date on which Landlord advises Tenant of the applicable Base Rent rate for the Renewal Term, shall either (i) give Landlord final binding written notice (“Binding Notice”) of Tenant’s exercise of its Renewal Option, or (ii) if Tenant disagrees with Landlord’s determination, provide Landlord with written notice of rejection (the “Rejection Notice”). If Tenant fails to provide Landlord with either a Binding Notice or Rejection Notice within such 15 day period, Tenant’s Renewal Option shall be null and void and of no further force and effect. If Tenant provides Landlord with a Binding Notice, Landlord and Tenant shall enter into the Renewal Amendment (as defined below) upon the terms and conditions set forth herein.

If Tenant provides Landlord with a Rejection Notice, Landlord and Tenant shall work together in good faith to agree upon the Prevailing Market rate for the Premises during the Renewal Term. When Landlord and Tenant have agreed upon the Prevailing Market rate for the Premises, such agreement shall be reflected in a written agreement between Landlord and Tenant, whether in a letter or otherwise, and Landlord and Tenant shall enter into the Renewal Amendment in accordance with the terms and conditions hereof. Notwithstanding the foregoing, if Landlord and Tenant are unable to agree upon the Prevailing Market rate for the Premises within 30 days after the date Tenant provides Landlord with the Rejection Notice, Tenant’s Renewal Option shall be deemed to be null and void and of no force and effect.

D. Renewal Amendment. If Tenant is entitled to and properly exercises its Renewal Option, Landlord shall prepare an amendment (the “Renewal Amendment”) to reflect changes in the Base Rent, Term, Termination Date and other appropriate terms. The Renewal Amendment shall be sent to Tenant within a reasonable time after Landlord’s receipt of the Binding Notice or other written agreement by Landlord and Tenant regarding the Prevailing Market rate, and Tenant shall execute and return the Renewal Amendment to Landlord within 15 days after Tenant’s receipt of same, but, upon final determination of the Prevailing Market rate applicable during the Renewal Term as described herein, an otherwise valid exercise of the Renewal Option shall be fully effective whether or not the Renewal Amendment is executed.

E. Definition of Prevailing Market. For purposes of this Renewal Option, “Prevailing Market” shall mean the arms length fair market annual rental rate per rentable square foot under renewal leases and amendments entered into on or about the date on which the Prevailing Market is being determined hereunder for space comparable to the Premises in the Building and office buildings comparable to the Building in the Burlingame, California area. The determination of Prevailing Market shall take into account any material economic differences between the terms of this Lease and any comparison lease or amendment, such as rent abatements, construction costs and other concessions and the manner, if any, in which the landlord under any such lease is reimbursed for operating expenses and taxes. The determination of Prevailing Market shall also take into consideration any reasonably anticipated changes in the Prevailing Market rate from the time such Prevailing Market rate is being determined and the time such Prevailing Market rate will become effective under this Lease.

F. Subordination. Notwithstanding anything herein to the contrary, Tenant’s Renewal Option is subject and subordinate to the expansion rights (whether such rights are designated as a right of first offer, right of first refusal, expansion option or otherwise) of any tenant of the Building existing on the date hereof.

3. Roof Space For Dish/Antenna.

A. Tenant shall have the right, in consideration for payments of $50.00 per month (the “Dish/Antenna Payments”), to lease space on the roof of the Building for the purpose of installing (in accordance with Section 9.03 of the Lease), operating and maintaining a inch ( ) dish/antenna or other communication device approved by the Landlord (the “Dish/Antenna”). The Dish/Antenna Payments shall constitute Additional Rent under the terms of the Lease and Tenant shall be required to make these payments in strict compliance with the terms of Section 4 of the Lease. The exact location of the space on the roof to be leased by Tenant shall be designated by Landlord and shall not exceed ( ) square feet (the “Roof Space”). Landlord reserves the right to relocate the Roof Space as reasonably necessary during the Term. Landlord’s designation shall take into account Tenant’s use of the Dish/Antenna. Notwithstanding the foregoing, Tenant’s right to install the Dish/Antenna shall be subject to the approval rights of Landlord and Landlord’s architect and/or engineer with respect to the plans and specifications of the Dish/Antenna, the manner in which the Dish/Antenna is attached to the roof of the Building and the manner in which any cables are run to and from the Dish/Antenna. The Dish/Antenna must be tagged with weatherproof labels showing manufacturer, model, frequency range, and name of Tenant. In addition, the cable between the Dish/Antenna and Tenant’s suite must be tagged in the telecom closet on each floor with a label showing Tenant’s name, phone number and suite number. The precise specifications and a general description of the Dish/Antenna along with all documents Landlord reasonably requires to review the installation of the Dish/Antenna (the “Plans and Specifications”) shall be submitted to Landlord for Landlord’s written approval no later than 20 days before Tenant commences to install the Dish/Antenna. Tenant shall be solely responsible for obtaining all necessary governmental and regulatory approvals and for the cost of installing, operating, maintaining and removing the Dish/Antenna. Tenant shall notify Landlord upon completion of the installation of the

Dish/Antenna. If Landlord determines that the Dish/Antenna equipment does not comply with the approved Plans and Specifications, that the Building has been damaged during installation of the Dish/Antenna or that the installation was defective, Landlord shall notify Tenant of any noncompliance or detected problems and Tenant immediately shall cure the defects. If the Tenant fails to immediately cure the defects, Tenant shall pay to Landlord upon demand the cost, as reasonably determined by Landlord, of correcting any defects and repairing any damage to the Building caused by such installation. If at any time Landlord, in its sole discretion, deems it necessary, Tenant shall provide and install, at Tenant’s sole cost and expense, appropriate aesthetic screening, reasonably satisfactory to Landlord, for the Dish/Antenna (the “Aesthetic Screening”).

B. Landlord agrees that Tenant, upon reasonable prior written notice to Landlord, shall have access to the roof of the Building and the Roof Space for the purpose of installing, maintaining, repairing and removing the Dish/Antenna, the appurtenances and the Aesthetic Screening, if any, all of which shall be performed by Tenant or Tenant’s authorized representative or contractors, which shall be approved by Landlord, at Tenant’s sole cost and risk. It is agreed, however, that only authorized engineers, employees or properly authorized contractors of Tenant, FCC (defined below) inspectors, or persons under their direct supervision will be permitted to have access to the roof of the Building and the Roof Space. Tenant further agrees to exercise firm control over the people requiring access to the roof of the Building and the Roof Space in order to keep to a minimum the number of people having access to the roof of the Building and the Roof Space and the frequency of their visits.

C. It is further understood and agreed that the installation, maintenance, operation and removal of the Dish/Antenna, the appurtenances and the Aesthetic Screening, if any, is not permitted to damage the Building or the roof thereof, or interfere with the use of the Building and roof by Landlord. Tenant agrees to be responsible for any damage caused to the roof or any other part of the Building, which may be caused by Tenant or any of its agents or representatives.

D. Tenant agrees to install only equipment of types and frequencies which will not cause unreasonable interference to Landlord or existing tenants of the Building. In the event Tenant’s equipment causes such interference, Tenant will change the frequency on which it transmits and/or receives and take any other steps necessary to eliminate the interference. If said interference cannot be eliminated within a reasonable period of time, in the judgment of Landlord, then Tenant agrees to remove the Dish/Antenna from the Roof Space.

E. Tenant shall, at its sole cost and expense, and at its sole risk, install, operate and maintain the Dish/Antenna in a good and workmanlike manner, and in compliance with all Building, electric, communication, and safety codes, ordinances, standards, regulations and requirements, now in effect or hereafter promulgated, of the Federal Government, including, without limitation, the Federal Communications Commission (the “FCC”), the Federal Aviation Administration (“FAA”) or any successor agency of either the FCC or FAA having jurisdiction over radio or telecommunications, and of the state, city and county in which the Building is located. Under this Lease, the Landlord and its agents assume no responsibility for the licensing, operation and/or maintenance of Tenant’s equipment. Tenant has the responsibility of carrying out the terms of its FCC license in all respects. The Dish/Antenna shall be connected to Landlord’s power supply in strict compliance with all applicable Building, electrical, fire and safety codes. Neither Landlord nor its agents shall be liable to Tenant for any stoppages or shortages of electrical power furnished to the Dish/Antenna or the Roof Space because of any act, omission or requirement of the public utility serving the Building, or the act or omission of any other tenant, invitee or licensee or their respective agents, employees or contractors, or for any other cause beyond the reasonable control of Landlord, and Tenant shall not be entitled to any rental abatement for any such stoppage or shortage of electrical power. Neither Landlord nor its agents shall have any responsibility or liability for the conduct or safety of any of Tenant’s representatives, repair, maintenance and engineering personnel while in or on any part of the Building or the Roof Space.

F. The Dish/Antenna, the appurtenances and the Aesthetic Screening, if any, shall remain the personal property of Tenant, and shall be removed by Tenant at its own expense at the expiration or earlier termination of this Lease or Tenant’s right to possession hereunder. Tenant shall repair any damage caused by such removal, including the patching of any holes to match, as closely as possible, the color surrounding the area where the equipment and appurtenances were attached. Tenant agrees to maintain all of the Tenant’s equipment placed on or about the roof or in any other part of the Building in proper operating condition and maintain same in satisfactory condition as to appearance

and safety in Landlord’s sole discretion. Such maintenance and operation shall be performed in a manner to avoid any interference with any other tenants or Landlord. Tenant agrees that at all times during the Term, it will keep the roof of the Building and the Roof Space free of all trash or waste materials produced by Tenant or Tenant’s agents, employees or contractors.

G. In light of the specialized nature of the Dish/Antenna, Tenant shall be permitted to utilize the services of its choice for installation, operation, removal and repair of the Dish/Antenna, the appurtenances and the Aesthetic Screening, if any, subject to the reasonable approval of Landlord. Notwithstanding the foregoing, Tenant must provide Landlord with prior written notice of any such installation, removal or repair and coordinate such work with Landlord in order to avoid voiding or otherwise adversely affecting any warranties granted to Landlord with respect to the roof. If necessary, Tenant, at its sole cost and expense, shall retain any contractor having a then existing warranty in effect on the roof to perform such work (to the extent that it involves the roof), or, at Tenant’s option, to perform such work in conjunction with Tenant’s contractor. In the event the Landlord contemplates roof repairs that could affect Tenant’s Dish/Antenna, or which may result in an interruption of the Tenant’s telecommunication service, Landlord shall formally notify Tenant at least 30 days in advance (except in cases of an emergency) prior to the commencement of such contemplated work in order to allow Tenant to make other arrangements for such service.

H. Tenant shall not allow any provider of telecommunication, video, data or related services (“Communication Services”) to locate any equipment on the roof of the Building or in the Roof Space for any purpose whatsoever, nor may Tenant use the Roof Space and/or Dish/Antenna to provide Communication Services to an unaffiliated tenant, occupant or licensee of another building, or to facilitate the provision of Communication Services on behalf of another Communication Services provider to an unaffiliated tenant, occupant or licensee of the Building or any other building.

I. Tenant acknowledges that Landlord may at some time establish a standard license agreement (the “License Agreement”) with respect to the use of roof space by tenants of the Building. Tenant, upon request of Landlord, shall enter into such License Agreement with Landlord provided that such agreement does not materially alter the rights of Tenant hereunder with respect to the Roof Space.

J. Tenant specifically acknowledges and agrees that the terms and conditions of Section 13 of the Lease (Indemnity and Waiver of Claims) shall apply with full force and effect to the Roof Space and any other portions of the roof accessed or utilized by Tenant, its representatives, agents, employees or contractors.

K. If Tenant defaults under any of the terms and conditions of this Section or the Lease, and Tenant fails to cure said default within the time allowed by Section 18 of the Lease, Landlord shall be permitted to exercise all remedies provided under the terms of the Lease, including removing the Dish/Antenna, the appurtenances and the Aesthetic Screening, if any, and restoring the Building and the Roof Space to the condition that existed prior to the installation of the Dish/Antenna, the appurtenances and the Aesthetic Screening, if any. If Landlord removes the Dish/Antenna, the appurtenances and the Aesthetic Screening, if any, as a result of an uncured default, Tenant shall be liable for all costs and expenses Landlord incurs in removing the Dish/Antenna, the appurtenances and the Aesthetic Screening, if any, and repairing any damage to the Building, the roof of the Building and the Roof Space caused by the installation, operation or maintenance of the Dish/Antenna, the appurtenances, and the Aesthetic Screening, if any.

EXHIBIT H

ASBESTOS NOTIFICATION

As you may know, asbestos, because of its insulating and fire-resistant properties, was historically used in some construction materials. California’s Connelly Act, as well as federal OSHA and some other California rules, now require building owners and landlords to make certain notifications regarding known asbestos-containing materials (“ACM”) and presumed ACMs (“PACM”). PACM consists of certain older construction materials which commonly contained asbestos. This Exhibit is designed to provide you with the required ACM and PACM notifications.

ACM

Our asbestos survey for the Building did not note the presence, location or quantity of ACM in the Building.

PACM

PACM consists of thermal system insulation and surfacing material found in buildings constructed prior to 1981, and asphalt or vinyl flooring installed prior to 1981. “Surfacing material” means material that is sprayed-on, troweled-on or otherwise applied to surfaces (such as acoustical plaster on ceilings and fireproofing materials on structural members, or other materials on surfaces for acoustical, fireproofing, and other purposes). Because this Building was constructed prior to 1981, PACM may be present. Our asbestos survey(s) for the Building note the presence, location and quantity of the PACM as follows:

• Roof: penthouse, thermal pipe insulation; and boiler room, hot water heater insulation.

The fact that our survey(s) may identify such materials as PACM does not necessarily mean that no other PACM exists in the Building. Please be advised that if any thermal system insulation, asphalt or vinyl flooring or surfacing material, of the type described above, are found to be present in the Building, such materials must be considered PACM unless properly tested and shown otherwise.

Because of the potential presence of PACM in the Building, we are providing you with the following warning, which is commonly known as a California Proposition 65 warning:

WARNING: This Building contains asbestos, a chemical known to the State of California to cause cancer.

In addition, you should be aware that there are certain potential health risks that may result from exposure to asbestos. Because we are not physicians, scientists or industrial hygienists, we have no special knowledge of the health impact of exposure to asbestos. However, we hired an environmental consulting firm to prepare an asbestos Operations and Maintenance Plan (“O&M Plan”) to address asbestos matters at the Building. The O&M Plan is designed to minimize the potential for a release of asbestos fibers and outlines a schedule of actions to be undertaken with respect to asbestos. The written O&M Plan is available for your review at our Building Management Office during regular business hours, and a copy of the O&M Plan will be provided to you upon request.

In general, the written O&M Plan describes the risks associated with asbestos exposure and how to prevent such exposure. The O&M Plan describes those risks as follows: asbestos is not a significant health concern unless asbestos fibers are released and inhaled. If inhaled, asbestos fibers can accumulate in the lungs and, as exposure increases, the risk of disease (such as asbestosis and cancer) increases. However, measures to minimize exposure and consequently minimize the accumulation of fibers, reduces the risk of adverse health effects.

The O&M Plan is designed to safely manage the ACM and PACM in the Building and to avoid the inadvertent disturbance of such ACM or PACM. To that end, the O&M Plan provides for the training of building housekeeping and maintenance personnel so that they can conduct their work without causing a release of asbestos fibers. As part of the O&M Plan, we maintain records of all asbestos-related activities and the results of any asbestos survey, sampling or monitoring conducted in the Building.

The written O&M Plan describes a number of activities which should be avoided in order to prevent a release of asbestos fibers in the Building. In particular, you should be aware that some of the activities which may present a health risk by causing an airborne release of asbestos fibers include moving, drilling, boring or otherwise disturbing ACM or PACM. Consequently, such activities should not be attempted by any person not qualified to handle ACM or PACM. In other words, you must obtain the

approval of the building management prior to engaging in any such activities. Please contact the Property Manager for more information in this regard. In addition, please contact the Property Manager if you notice any deterioration or disturbance of ACM or PACM. Also, note that the identification of ACM and PACM in this Exhibit is based on actual knowledge and assumptions that the law requires us to make: such materials do not necessarily comprise all asbestos in the Building.

Please be aware that you may have certain obligations under California and federal laws with regard to the ACM and PACM in the Building, including obligations to notify your own employees, contractors, subtenants, agents and others of the presence of ACM and PACM. You are solely responsible for complying with all such applicable laws.

Please contact the Property Manager if you have any questions regarding the contents of this Exhibit.
