PREMISES, TERM, FAILURE TO GIVE POSSESSION, AND PARKING

2.1 LEASE OF PREMISES

Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the Premises for the Term and upon the terms, covenants and conditions provided in this Lease. In the event Landlord delivers possession of the Premises to Tenant prior to the Commencement Date, Tenant shall be subject to all of the terms, covenants and conditions of this Lease (except with respect to the payment of Rent) as of the date of such possession.

2.2 TERM

(a) The Commencement Date shall be the date determined as follows:

(1) If the Landlord Work is Substantially Complete on or before the Projected Commencement Date, then on the date which is the earlier to occur of:

(i) the Projected Commencement Date, or

(ii) the date Tenant first occupies all or part of the Premises for the conduct of business; or

(2) If the Landlord Work is not Substantially Complete by the Projected Commencement Date, then on the date on which the Landlord Work is Substantially Complete.

(b) Within thirty (30) days following the occurrence of the Commencement Date, Landlord and Tenant shall enter into an agreement (the form of which is attached hereto as Rider 1) confirming the Commencement Date and the Expiration Date. If Tenant fails to enter into such agreement, then the Commencement Date and the Expiration Date shall be the dates designated by Landlord in such agreement.

2.3 FAILURE TO GIVE POSSESSION

If Landlord shall be unable to give possession of the Premises on the Projected Commencement Date by reason of the following: (i) the Building has not been sufficiently completed to make the Premises ready for occupancy, (ii) the Landlord Work is not Substantially Complete, (iii) the holding over or retention of possession of any tenant, tenants or occupants, or (iv) for any other reason, then Landlord shall not be subject to any liability for the failure to give possession on said date. Under such circumstances the rent reserved and covenanted to be paid herein shall not commence until the Premises are made available to Tenant by Landlord, and no such failure to give possession on the Projected Commencement Date shall affect the validity of this Lease or the obligations of the Tenant hereunder. At the option of Landlord to be exercised within thirty (30) days of the delayed delivery of possession to Tenant, the Lease shall be amended so that the Term shall be extended by the period of time possession is delayed. The said Premises shall be deemed to be ready for Tenant’s occupancy in the event Landlord’s Work is Substantially Complete, or if the delay in the availability of the Premises for occupancy shall

be due to any Tenant Delay and/or default on the part of Tenant and/or its subtenant or subtenants. In the event of any dispute as to whether the Landlord Work is Substantially Complete, the decision of Landlord’s architect shall be final and binding on the parties.

2.4 CONDITION OF PREMISES

Tenant shall notify Landlord in writing within ninety (90) days after the later of Substantial Completion of the Landlord Work or when Tenant takes possession of the Premises of any defects in the Premises claimed by Tenant or in the materials or workmanship furnished by Landlord in completing the Landlord Work provided however that Tenant shall have one hundred eighty (180) days to notify Landlord with respect to defects in the HVAC system. Except for defects stated in such notice, Tenant shall be conclusively deemed to have accepted the Premises “AS IS” in the condition existing on the date Tenant first takes possession, and to have waived all claims relating to the condition of the Premises. Landlord shall proceed diligently to correct the defects stated in such notice unless Landlord disputes the existence of any such defects. In the event of any dispute as to the existence of any such defects, the decision of Landlord’s architect shall be final and binding on the parties. No agreement of Landlord to alter, remodel, decorate, clean or improve the Premises or the Real Property and no representation regarding the condition of the Premises or the Real Property has been made by or on behalf of Landlord to Tenant, except as may be specifically stated in this Lease or in the Workletter.

2.5 PARKING

During the Term, Tenant may use the number of spaces specified in Section 1.1 for parking. There shall be no charge for such parking during the Term. The locations and type of parking shall be designated by Landlord or Landlord’s parking operator from time to time. Tenant acknowledges and agrees that the parking spaces serving the Project may include tandem parking and a mixture of spaces for compact vehicles as well as full-size passenger automobiles, and that Tenant shall not use parking spaces for vehicles larger than the striped size of the parking spaces. All vehicles utilizing Tenant’s parking privileges shall prominently display identification stickers or other markers, and/or have passes or keycards for ingress and egress, as may be required and provided by Landlord or its parking operator from time to time. Tenant shall comply with any and all parking rules and regulations from time to time established by Landlord or Landlord’s parking operator, including a requirement that Tenant pay to Landlord or Landlord’s parking operator a charge for loss and replacement of passes, keycards, identification stickers or markers, and for any and all loss or other damage caused by persons or vehicles related to use of Tenant’s parking privileges. Tenant shall not allow any vehicles using Tenant’s parking privileges to be parked, loaded or unloaded except in accordance with this Section, including in the areas and in the manner designated by Landlord or its parking operator for such activities. If any vehicle is using the parking or loading areas contrary to any provision of this Section, Landlord or its parking operator shall have the right, in addition to all other rights and remedies of Landlord under this Lease, to remove or tow away the vehicle without prior notice to Tenant, and the cost thereof shall be paid to Landlord within ten (10) days after notice from Landlord to Tenant.

2.6 RIGHT OF FIRST OFFER.

(a) Landlord shall provide Tenant with a notice in the event that during the Term, Available Premises (as hereinafter defined) become available to lease to third parties (the “Right of First Offer”).

(b) Available Premises shall mean lab space (not space that has previously used for office purposes) which is located on the 5th floor of the Building which becomes available for leasing to third parties. Space shall not be deemed to be Available Premises if an existing tenant in such space renews or extends its term whether pursuant to the terms of an extension right or otherwise or if Kinemed exercises its prior rights with respect to such space.

For a period of fifteen (15) business days after receipt of Landlord’s notice with respect to the Available Premises, Landlord and Tenant shall negotiate in good faith concerning the leasing of such space but neither party shall be obligated to enter into a lease of the Available Premises unless the parties mutually agree on the terms and conditions of such lease. Such lease shall be upon market terms, taking into account, among other criteria, the then creditworthiness of Tenant. Tenant acknowledges that the term for the Available Premises may be different from the Term for the Premises and that the rent and tenant improvement package for the Available Premises may be different than the rent and tenant improvement package for the Premises. During the Negotiation Period, Landlord shall not enter into negotiations with any third party concerning the Available Premises. In the event that Tenant fails to exercise its Right of First Offer with respect to a particular Available Premises, Tenant’s rights in connection with that particular Available Premises shall expire. Notwithstanding the foregoing, Tenant’s Right of First Offer shall continue to exist during the Term for other Available Premises on the 5^th floor which was not subject to a previous notice.

(c) Notwithstanding anything to the contrary contained, herein, all rights of Tenant pursuant to this Section 2.6 shall automatically terminate without notice and shall be of no further force and effect, whether or not Tenant has timely exercised the Right of First Offer granted herein, if a Default exists at the time of exercise of the Right of First Offer or at the time of commencement of the term, or (ii) this Lease has been assigned except to an Affiliate of Tenant.

ARTICLE 3

RENT

Tenant agrees to pay to Landlord at the first office specified in Section 1.1, or to such other persons, or at such other places designated by Landlord, without any prior demand therefor in immediately available funds and without any deduction or offset whatsoever, Rent, including Monthly Base Rent and Rent Adjustments in accordance with Article Four, during the Term. Monthly Base Rent shall be paid monthly in advance on the first day of each month of the Term, except that the first installment of Monthly Base Rent shall be paid by Tenant to Landlord concurrently with execution of this Lease. Monthly Base Rent shall be prorated for partial months within the Term. Unpaid Rent shall bear interest at the Default Rate from the date due

until paid. Tenant’s covenant to pay Rent shall be independent of every other covenant in this Lease.

ARTICLE 4

RENT ADJUSTMENTS AND PAYMENTS

4.1 RENT ADJUSTMENTS

Except as expressly set forth in Section 1.1 (13) with respect to utilities and janitorial services, Tenant shall pay to Landlord Rent Adjustments with respect to each Lease Year after the Base Year as follows:

(i) The Rent Adjustment Deposit representing Tenant’s Share of increases in Operating Expenses for the applicable Lease Year over the Operating Expenses in the Base Year, monthly during the Term with the payment of Monthly Base Rent; and

(ii) The Rent Adjustment Deposit representing Tenant’s Share of increases in Taxes for the applicable Lease Year over the Taxes in the Base Year, monthly during the Term with the payment of Monthly Base Rent; and

(iii) Any Rent Adjustments due in excess of the Rent Adjustment Deposits in accordance with Section 4.2. Rent Adjustments due from Tenant to Landlord for any Lease Year after the Base Year shall be Tenant’s Share of Operating Expenses for such year and Tenant’s Share of Taxes for such year.

Notwithstanding the foregoing, Tenant shall pay to Landlord the Rent Adjustment Deposit for utilities and janitorial services furnished to the Premises or to the Common Areas commencing from and after the Commencement Date.

4.2 STATEMENT OF LANDLORD

As soon as feasible after the expiration of each calendar year, Landlord will furnish Tenant a statement (“Landlord’s Statement”) showing the following:

(i) Operating Expenses and Taxes for the calendar year;

(ii) The amount of Rent Adjustments due Landlord for the last calendar year, less credit for Rent Adjustment Deposits paid, if any; and

(iii) Any change in the Rent Adjustment Deposit due monthly in the current calendar year, including the amount or revised amount due for months preceding any such change pursuant to Landlord’s Statement.

Tenant shall pay to Landlord within ten (10) days after receipt of such statement any amounts for Rent Adjustments then due in accordance with Landlord’s Statement. Any amounts due from Landlord to Tenant pursuant to this Section shall be credited to the Rent Adjustment Deposit next coming due, or refunded to Tenant if the Term has already expired provided Tenant

is not in default hereunder. No interest or penalties shall accrue on any amounts that Landlord is obligated to credit or refund to Tenant by reason of this Section 4.2. Landlord’s failure to deliver Landlord’s Statement or to compute the amount of the Rent Adjustments shall not constitute a waiver by Landlord of its right to deliver such items nor constitute a waiver or release of Tenant’s obligations to pay such amounts. The Rent Adjustment Deposit shall be credited against Rent Adjustments due for the applicable Lease Year. During the last complete Lease Year or during any partial Lease Year in which the Lease terminates, Landlord may include in the Rent Adjustment Deposit its estimate of Rent Adjustments which may not be finally determined until after the termination of this Lease. Tenant’s obligation to pay Rent Adjustments survives the expiration or termination of the Lease. Notwithstanding the foregoing, in no event shall the sum of Monthly Base Rent and the Rent Adjustments be less than the Monthly Base Rent payable.

4.3 BOOKS AND RECORDS

Landlord shall maintain books and records showing Operating Expenses and Taxes in accordance with sound accounting and management practices, consistently applied. The Tenant or its representative (which representative shall be a certified public accountant licensed to do business in the state in which the Property is located and whose primary business is certified public accounting and who shall not be paid on a contingency basis) shall have the right, for a period of sixty (60) days following the date upon which Landlord’s Statement is delivered to Tenant, to examine the Landlord’s books and records with respect to the items in the foregoing statement of Operating Expenses and Taxes during normal business hours, upon written notice, delivered at least three (3) business days in advance. If Tenant does not object in writing to Landlord’s Statement within ninety (90) days of Tenant’s receipt thereof, specifying the nature of the item in dispute and the reasons therefor, then Landlord’s Statement shall be considered final and accepted by Tenant. If Tenant does dispute any Landlord’s Statement, Tenant shall deliver a copy of any such audit to Landlord at the time of notification of the dispute. If Tenant does not provide such notice of dispute and a copy of such audit to Landlord within such ninety day (90) day period, it shall be deemed to have waived such right to dispute Landlord’s Statement. If it is determined that Landlord’s Statement overstated Operating Expenses by five percent (5%) or more, Landlord shall reimburse Tenant the reasonable third party costs incurred by Tenant with respect to such audit. Any amount due to the Landlord as shown on Landlord’s Statement, whether or not disputed by Tenant as provided herein shall be paid by Tenant when due as provided above, without prejudice to any such written exception. 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. Upon resolution of any dispute with respect to Operating Expenses and Taxes, Tenant shall either pay Landlord any shortfall or Landlord shall credit Tenant with respect to any overages paid by Tenant. The records obtained by Tenant shall be treated as confidential and neither Tenant nor any of its representatives or agents shall disclose or discuss the information set forth in the audit to or with any other person or entity (“Confidentiality Requirement”). Tenant shall indemnify and hold Landlord harmless for any losses or damages arising out of the breach of the Confidentiality Requirement. 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.

4.4 PARTIAL OCCUPANCY

For purposes of determining the Base Year Operating Expenses and Rent Adjustments, if the Building and/or Project is not fully occupied during all or a portion of any year during the Term, Landlord shall make appropriate adjustments to the Operating Expenses for such year that vary with occupancy employing sound accounting and management principles consistently applied, to determine the amount of Operating Expenses that would have been paid or incurred by Landlord had the Building and/or Project been fully occupied, and the amount so determined shall be deemed to have been the amount of Operating Expenses for such year. In the event that the Real Property is not fully assessed for all or a portion of any year during the Term, then Taxes shall be adjusted to an amount which would have been payable in such year if the Real Property had been fully assessed.

4.5 TENANT OR LEASE SPECIFIC TAXES

In addition to Monthly Base Rent, Rent Adjustments, Rent Adjustment Deposits and other charges to be paid by Tenant, Tenant shall pay to Landlord, upon demand, any and all taxes payable by Landlord (other than federal or state inheritance, general income, gift or estate taxes) whether or not now customary or within the contemplation of the parties hereto: (a) upon, allocable to, or measured by the Rent payable hereunder, including any gross receipts tax or excise tax levied by any governmental or taxing body with respect to the receipt of such rent; or (b) upon or with respect to the possession, leasing, operation, management, maintenance, alteration, repair, use or occupancy by Tenant of the Premises or any portion thereof; or (c) upon the measured value of Tenant’s personal property located in the Premises or in any storeroom or any other place in the Premises or the Property, or the areas used in connection with the operation of the Property, it being the intention of Landlord and Tenant that, to the extent possible, such personal property taxes shall be billed to and paid directly by Tenant; (d) resulting from Landlord Work, Tenant Work or Tenant Alterations to the Premises, whether title thereto is in Landlord or Tenant; or (e) upon this transaction. Taxes paid by Tenant pursuant to this Section 4.5 shall not be included in any computation of Taxes payable pursuant to Sections 4.1 and 4.2.

ARTICLE 5

SECURITY DEPOSIT

Tenant concurrently with the execution of this Lease shall pay to Landlord in immediately available funds the Security Deposit. The Security Deposit may be applied by Landlord to cure, in whole or part, any default of Tenant under this Lease, and upon notice by Landlord of such application, Tenant shall replenish the Security Deposit in full by paying to Landlord within ten (10) days of demand the amount so applied. Landlord’s application of the Security Deposit shall not constitute a waiver of Tenant’s default to the extent that the Security Deposit does not fully compensate Landlord for all losses, damages, costs and expenses incurred by Landlord in connection with such default and shall not prejudice any other rights or remedies available to Landlord under this Lease or by Law. Landlord shall not pay any interest on the Security Deposit. Landlord shall not be required to keep the Security Deposit separate from its general accounts. The Security Deposit shall not be deemed an advance payment of Rent or a

measure of damages for any default by Tenant under this Lease, nor shall it be a bar or defense of any action that Landlord may at any time commence against Tenant. In the absence of evidence satisfactory to Landlord of an assignment of the right to receive the Security Deposit or the remaining balance thereof, Landlord may return the Security Deposit to the original Tenant, regardless of one or more assignments of this Lease. Upon the transfer of Landlord’s interest under this Lease, Landlord’s obligation to Tenant with respect to the Security Deposit shall terminate upon transfer to the transferee of the Security Deposit, or any balance thereof. If Tenant shall fully and faithfully comply with all the terms, provisions, covenants, and conditions of this Lease, the Security Deposit, or any balance thereof, shall be returned to Tenant within thirty (30) days after Landlord recovers possession of the Premises or such longer time as may be permissible under Law. Tenant hereby waives any and all rights of Tenant under the provisions of Section 1950.7 of the California Civil Code or other Law regarding security deposits.

ARTICLE 6

6.1 LANDLORD’S GENERAL SERVICES

(a) So long as the Lease is in full force and effect, Landlord shall furnish the following services the cost of which services shall be included in Operating Expenses or paid directly by Tenant to the utility or service provider:

(1) heat, ventilation and air-conditioning (“HVAC”) in the Premises during Standard Operating Hours as necessary in Landlord’s reasonable judgment for the comfortable occupancy of the Premises under normal business office and lab operations, subject to compliance with all applicable voluntary and mandatory regulations and Laws;

(2) tempered and cold water for use in the labs and in lavatories in common with other tenants from the regular supply of the Building;

(b) If Tenant uses heat generating machines or equipment in the Premises not envisioned in the original equipment matrix provided by Tenant to Landlord, to an extent which adversely affects the temperature otherwise maintained by the air-cooling system or whenever the occupancy or electrical load adversely affects the temperature otherwise maintained by the air-cooling system, Landlord reserves the right to install or to require Tenant to install

supplementary air-conditioning units in the Premises. Tenant shall bear all costs and expenses related to the installation, maintenance and operation of such units.

6.2 ELECTRICAL SERVICES

(a) So long as the Lease is in full force and effect and Tenant has paid all Rent then due, Landlord shall furnish to the Premises as an Operating Expense or a service which is paid directly by Tenant to the utility provider, electric current for general office use, including normal lighting, normal business office machines and customary janitorial service. Notwithstanding any provision of the Lease to the contrary, without, in each instance, the prior written approval of Landlord, in Landlord’s prudent business judgment, Tenant shall not make any alterations or additions to the electric equipment or systems. Tenant’s use of electric current shall at no time exceed the capacity of the wiring, feeders and risers providing electric current to the Premises or the Building. The consent of Landlord to the installation of electric equipment shall not relieve Tenant from the obligation to limit usage of electricity to no more than such capacity.

(b) Landlord shall install one or more meters to measure electric current furnished to the Premises.

(c) So long as the Lease is in full force and effect and Tenant has paid all Rent then due, Landlord shall furnish to the Premises replacement lamps, bulbs, ballasts and starters used in any normal Building lighting installed in the Premises, except that if the replacement or repair of such items is a result of negligence of Tenant, its employees, agents, servants, licensees, subtenants, contractors or invitees, such cost shall be paid by Tenant within ten days after notice from Landlord and shall not be included as part of Operating Expenses.

6.3 ADDITIONAL AND AFTER HOUR SERVICES

Basic hours of electricity for provision of electricity are twenty-four hours a day, seven days a week. At Tenant’s written request, Landlord shall furnish additional quantities of any of the services or utilities specified in Section 6.1, if Landlord can reasonably do so, on the terms set forth herein. For services or utilities requested by Tenant and furnished by Landlord, Tenant shall pay to Landlord as a charge therefor Landlord’s prevailing rates charged from time to time for such services and utilities. If Tenant shall fail to make any such payment, Landlord may, upon notice to Tenant and in addition to Landlord’s other remedies under this Lease, discontinue any or all of such additional services.

6.4 TELEPHONE SERVICES

All telegraph, telephone, and communication connections which Tenant may desire shall be subject to Landlord’s prior written approval, in Landlord’s reasonable discretion, and the location of all wires and the work in connection therewith shall be performed by contractors approved by Landlord and shall be subject to the direction of Landlord, except that such approval is not required as to Tenant’s telephone equipment (including cabling) within the Premises and from the Premises in a route designated by Landlord to any telephone cabinet or panel provided (as existing or as installed as part of Landlord’s Work, if any) on Tenant’s floor for Tenant’s connection to the telephone cable serving the Building so long as Tenant’s equipment does not require connections different than or additional to those to the telephone cabinet or panel

provided. Tenant shall label cabling installed by it to avoid interfering with other Tenants. Except to the extent of such cabling within the Premises or from the Premises to such telephone cabinet or panel, Landlord reserves the right to designate and control the entity or entities providing telephone or other communication cable installation, removal, repair and maintenance in the Building and to restrict and control access to telephone cabinets or panels. In the event Landlord designates a particular vendor or vendors to provide such cable installation, removal, repair and maintenance for the Building, Tenant agrees to abide by and participate in such program. Tenant shall be responsible for and shall pay all costs incurred in connection with the installation of telephone cables and communication wiring in the Premises, including any hook-up, access and maintenance fees related to the installation of such wires and cables in the Premises and the commencement of service therein, and the maintenance thereafter of such wire and cables; and there shall be included in Operating Expenses for the Building all installation, removal, hook-up or maintenance costs incurred by Landlord in connection with telephone cables and communication wiring serving the Building which are not allocable to any individual users of such service but are allocable to the Building generally. If Tenant fails to maintain all telephone cables and communication wiring in the Premises and such failure affects or interferes with the operation or maintenance of any other telephone cables or communication wiring serving the Building, Landlord or any vendor hired by Landlord may enter into and upon the Premises forthwith and perform such repairs, restorations or alterations as Landlord deems necessary in order to eliminate any such interference (and Landlord may recover from Tenant all of Landlord’s costs in connection therewith). If required by Landlord, no later than the Termination Date Tenant shall remove all telephone cables and communication wiring installed by Tenant for and during Tenant’s occupancy. Tenant agrees that neither Landlord nor any of its agents or employees shall be liable to Tenant, or any of Tenant’s employees, agents, customers or invitees or anyone claiming through, by or under Tenant, for any damages, injuries, losses, expenses, claims or causes of action because of any interruption, diminution, delay or discontinuance at any time for any reason in the furnishing of any telephone or other communication service to the Premises and the Building.

6.5 DELAYS IN FURNISHING SERVICES

Tenant agrees that Landlord shall not be in breach of this Lease nor be liable to Tenant for damages or otherwise, for any failure to furnish, or a delay in furnishing, or a change in the quantity or character of any service when such failure, delay or change is occasioned, in whole or in part, by repairs, improvements or mechanical breakdowns by the act or default of Tenant or other parties or by an event of Force Majeure. No such failure, delay or change shall be deemed to be an eviction or disturbance of Tenant’s use and possession of the Premises, or relieve Tenant from paying Rent or from performing any other obligations of Tenant under this Lease, without any deduction or offset. Failure to any extent to make available, or any slowdown, stoppage, or interruption of, the specified utility services resulting from any cause, including changes in service provider or Landlord’s compliance with any voluntary or similar governmental or business guidelines now or hereafter published or any requirements now or hereafter established by any governmental agency, board, or bureau having jurisdiction over the operation of the Property shall not render Landlord liable in any respect for damages to either persons, property, or business, nor be construed as an eviction of Tenant or work an abatement of Rent, nor relieve Tenant of Tenant’s obligations for fulfillment of any covenant or agreement hereof. Should any equipment or machinery furnished by Landlord break down or for any cause cease to function

properly, Landlord shall use reasonable diligence to repair same promptly, but Tenant shall have no claim for abatement of Rent or damages on account of any interruption of service occasioned thereby or resulting therefrom unless such interruption of service is the result of a breach of Landlord’s obligations under this Lease.

6.6 CHOICE OF SERVICE PROVIDER

Tenant acknowledges that Landlord may, at Landlord’s sole option, to the extent permitted by applicable law, elect to change, from time to time, the company or companies which provide utility services to the Building, the Premises and/or its occupants. Notwithstanding anything to the contrary set forth in this Lease, Tenant acknowledges that Landlord has not and does not make any representations or warranties concerning the identity or identities of the company or companies which provide services to the Building and the Premises or its occupants and Tenant acknowledges that the choice of service providers and matters concerning the engagement and termination thereof shall be solely that of Landlord. The foregoing provision is not intended to modify, amend, change or otherwise derogate any provision of this Lease concerning the nature or type of service to be provided or any specific information concerning the amount thereof to be provided. Tenant agrees to cooperate with Landlord and each of its service providers in connection with any change in service or provider.

6.7 SIGNAGE

Initial Building standard signage will be installed by Landlord in the directory in the main lobby of the Building, in the listing of tenants in the elevator lobby for the floor on which the Premises is located and at Tenant’s main entry door to the Premises at Tenant’s sole cost and expense except to the extent that funds are available out of any Tenant Improvement Allowance, if any, provided pursuant to the Workletter. Any change in such initial signage shall be only with Landlord’s prior written consent, shall conform to Building standard signage and shall be at Tenant’s sole cost and expense.

ARTICLE 7

POSSESSION, USE AND CONDITION OF PREMISES

7.1 POSSESSION AND USE OF PREMISES

(a) Tenant shall be entitled to possession of the Premises when the Landlord Work is Substantially Complete. Tenant shall have access to the Premises seven (7) days a week, twenty-four (24) hours a day. Tenant shall occupy and use the Premises only for the uses specified in Section 1.1 to conduct Tenant’s business. Tenant shall not occupy or use the Premises (or permit the use or occupancy of the Premises) for any purpose or in any manner which: (1) is unlawful or in violation of any Law or Environmental Law; (2) may be dangerous to persons or property or which may increase the cost of, or invalidate, any policy of insurance carried on the Building or covering its operations; (3) is contrary to or prohibited by the terms and conditions of this Lease or the rules of the Building set forth in Article Eighteen; or (4) would tend to create or continue a nuisance.

(b) Landlord shall provide Tenant with Access Card Keys, the cost of which shall be deducted from the Tenant Improvement Allowance.

(c) Tenant shall comply with all Environmental Laws pertaining to Tenant’s occupancy and use of the Premises and concerning the proper storage, handling and disposal of any Hazardous Material introduced to the Premises, the Building or the Property by Tenant or other occupants of the Premises, or their employees, servants, agents, contractors, customers or invitees. Landlord shall comply with all Environmental Laws applicable to the Property other than those to be complied with by Tenant pursuant to the preceding sentence. Tenant shall not generate, store, handle or dispose of any Hazardous Material in, on, or about the Property without the prior written consent of Landlord, which may be withheld in Landlord’s sole discretion, except that such consent shall not be required to the extent of Hazardous Material packaged and contained in office products for consumer use in general business offices in quantities for ordinary day-to-day use provided such use does not give rise to, or pose a risk of, exposure to or release of Hazardous Material. In the event that Tenant is notified of any investigation or violation of any Environmental Law arising from Tenant’s activities at the Premises, Tenant shall immediately deliver to Landlord a copy of such notice. In such event or in the event Landlord reasonably believes that a violation of Environmental Law exists, Landlord may conduct such tests and studies relating to compliance by Tenant with Environmental Laws or the alleged presence of Hazardous Materials upon the Premises as Landlord deems desirable, all of which shall be completed at Tenant’s expense. Landlord’s inspection and testing rights are for Landlord’s own protection only, and Landlord has not, and shall not be deemed to have assumed any responsibility to Tenant or any other party for compliance with Environmental Laws, as a result of the exercise, or non-exercise of such rights. Tenant hereby indemnifies, and agrees to defend, protect and hold harmless, the Indemnitees from any and all loss, claim, demand, action, expense, liability and cost (including attorneys’ fees and expenses) arising out of or in any way related to the presence of any Hazardous Material introduced to the Premises during the Term by any party other than Landlord. In case of any action or proceeding brought against the Indemnitees by reason of any such claim, upon notice from Landlord, Tenant covenants to defend such action or proceeding by counsel chosen by Landlord, in Landlord’s sole discretion. Landlord reserves the right to settle, compromise or dispose of any and all actions, claims and demands related to the foregoing indemnity. If any Hazardous Material is released, discharged or disposed of on or about the Property and such release, discharge or disposal is not caused by Tenant or other occupants of the Premises, or their employees, servants, agents, contractors customers or invitees, such release, discharge or disposal shall be deemed casualty damage under Article Fourteen to the extent that the Premises are affected thereby; in such case, Landlord and Tenant shall have the obligations and rights respecting such casualty damage provided under such Article. Landlord has no actual knowledge that there are any Hazardous Materials in the Building in violation of applicable Environmental Laws. Notwithstanding the foregoing, Tenant shall have no liability for the amelioration or costs incurred by Landlord with respect to any Hazardous Materials that are not the responsibility of Tenant hereunder.

(d) Landlord and Tenant acknowledge that the Americans With Disabilities Act of 1990 (42 U.S.C. §12101 et seq.) and regulations and guidelines promulgated thereunder, as all of the same may be amended and supplemented from time to time (collectively referred to herein as the “ADA”) establish requirements for business operations, accessibility and barrier removal,

and that such requirements may or may not apply to the Premises, the Building and the Project depending on, among other things: (1) whether Tenant’s business is deemed a “public accommodation” or “commercial facility”, (2) whether such requirements are “readily achievable”, and (3) whether a given alteration affects a “primary function area” or triggers “path of travel” requirements. The parties hereby agree that: (a) Landlord shall be responsible for ADA Title III compliance in the Common Areas, except as provided below, (b) Tenant shall be responsible for ADA Title III compliance in the Premises, including any leasehold improvements or other work to be performed in the Premises under or in connection with this Lease, (c) Landlord may perform, or require that Tenant perform, and Tenant shall be responsible for the cost of, ADA Title III “path of travel” requirements triggered by Tenant Additions in the Premises, and (d) Landlord may perform, or require Tenant to perform, and Tenant shall be responsible for the cost of, ADA Title III compliance in the Common Areas necessitated by the Building being deemed to be a “public accommodation” instead of a “commercial facility” as a result of Tenant’s use of the Premises. Tenant shall be solely responsible for requirements under Title I of the ADA relating to Tenant’s employees.

7.2 LANDLORD ACCESS TO PREMISES; APPROVALS

(a) Tenant shall permit Landlord to erect, use and maintain pipes, ducts, wiring and conduits in and through the Premises, so long as Tenant’s use, layout or design of the Premises is not materially affected or altered. Landlord or Landlord’s agents shall have the right to enter upon the Premises in the event of an emergency, or to inspect the Premises, to perform janitorial and other services, to conduct safety and other testing in the Premises and to make such repairs, alterations, improvements or additions to the Premises or the Building or other parts of the Property as Landlord may deem necessary or desirable (including all alterations, improvements and additions in connection with a change in service provider or providers). Janitorial and cleaning services shall be performed after normal business hours. Any entry or work by Landlord may be during normal business hours and Landlord may use reasonable efforts to ensure that any entry or work shall not materially interfere with Tenant’s occupancy of the Premises.

(b) If Tenant shall not be personally present to permit an entry into the Premises when for any reason an entry therein shall be necessary or permissible, Landlord (or Landlord’s agents), after attempting to notify Tenant (unless Landlord believes an emergency situation exists), may enter the Premises without rendering Landlord or its agents liable therefor, and without relieving Tenant of any obligations under this Lease.

(c) Landlord may enter the Premises for the purpose of conducting such inspections, tests and studies as Landlord may deem desirable or necessary to confirm Tenant’s compliance with all Laws and Environmental Laws or for other purposes necessary in Landlord’s reasonable judgment to ensure the sound condition of the Property and the systems serving the Property. Landlord’s rights under this Section 7.2(c) are for Landlord’s own protection only, and Landlord has not, and shall not be deemed to have assumed, any responsibility to Tenant or any other party as a result of the exercise or non-exercise of such rights, for compliance with Laws or Environmental Laws or for the accuracy or sufficiency of any item or the quality or suitability of any item for its intended use.

(d) Landlord may do any of the foregoing, or undertake any of the inspection or work described in the preceding paragraphs without such action constituting an actual or constructive eviction of Tenant, in whole or in part, or giving rise to an abatement of Rent by reason of loss or interruption of business of the Tenant, or otherwise.

(e) The review, approval or consent of Landlord with respect to any item required or permitted under this Lease is for Landlord’s own protection only, and Landlord has not, and shall not be deemed to have assumed, any responsibility to Tenant or any other party, as a result of the exercise or non-exercise of such rights, for compliance with Laws or Environmental Laws or for the accuracy or sufficiency of any item or the quality or suitability of any item for its intended use.

7.3 QUIET ENJOYMENT

Landlord covenants, in lieu of any implied covenant of quiet possession or quiet enjoyment, that so long as Tenant is in compliance with the covenants and conditions set forth in this Lease, Tenant shall have the right to quiet enjoyment of the Premises without hindrance or interference from Landlord or those claiming through Landlord, and subject to the covenants and conditions set forth in the Lease and to the rights of any Mortgagee or ground lessor.

ARTICLE 8

MAINTENANCE

8.1 LANDLORD’S MAINTENANCE

Subject to the provisions of Articles Four and Fourteen, Landlord shall maintain and make necessary repairs to the structure, foundations, roofs, exterior walls, and the structural elements of the Building, the electrical, plumbing, heating, ventilating, air-conditioning, mechanical, communication, security and the fire and life safety systems of the Building and those corridors, washrooms and lobbies which are Common Areas of the Building and plate glass breakage in the Building, except that: (a) Landlord shall not be responsible for the maintenance or repair of any floor or wall coverings in the Premises or any of such systems which are located within the Premises and are supplemental or special to the Building’s standard systems; and (b) the cost of performing any of said maintenance or repairs whether to the Premises or to the Building caused by the negligence of Tenant, its employees, agents, servants, licensees, subtenants, contractors or invitees, shall be paid by Tenant, subject to the waivers set forth in Section 16.4. Landlord shall not be liable to Tenant for any expense, injury, loss or damage resulting from work done in or upon, or in connection with the use of, any adjacent or nearby building, land, street or alley.

8.2 TENANT’S MAINTENANCE

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. Tenant hereby waives all right to make repairs at the expense of Landlord or in lieu thereof to vacate the Premises and its other similar rights as provided in California Civil Code Sections 1932(1), 1941 and 1942 or any other Legal Requirement (whether now or hereafter in effect). In addition to the foregoing, Tenant shall be responsible for repairing all special tenant fixtures and improvements, including garbage disposals, showers, plumbing, and appliances.

ARTICLE 9

ALTERATIONS AND IMPROVEMENTS

9.1 TENANT ALTERATIONS

(a) Except for completion of Tenant Work undertaken by Tenant pursuant to the Workletter, the following provisions shall apply to the completion of any Tenant Alterations:

(1) Tenant shall not, except as provided herein, without the prior written consent of Landlord, which consent shall not be unreasonably withheld, make or cause to be made any Tenant Alterations in or to the Premises or any Property systems serving the Premises. Prior to making any Tenant Alterations, Tenant shall give Landlord ten (10) days prior written notice (or such earlier notice as would be necessary pursuant to applicable Law) to permit Landlord sufficient time to post appropriate notices of non-responsibility. Subject to all other requirements of this Article Nine, Tenant may undertake Decoration work without Landlord’s prior written consent. Tenant shall furnish Landlord with the names and addresses of all contractors and subcontractors and copies of all contracts. All Tenant Alterations shall be completed at such time and in such manner as Landlord may from time to time designate, and only by contractors or mechanics approved by Landlord, which approval shall not be unreasonably withheld, provided, however, that Landlord may, in its sole discretion, specify the engineers and contractors to perform all work relating to the Building’s systems (including the mechanical, heating, plumbing, security, ventilating, air-conditioning, electrical, communication and the fire and life safety systems in the Building). The contractors, mechanics and engineers who may be used are further limited to those whose work will not cause or threaten to cause disharmony or interference with Landlord or other tenants in the Building and their respective agents and contractors performing work in or about the Building. Landlord may further condition its consent upon Tenant furnishing to Landlord and Landlord approving prior to the commencement of any work or delivery of materials to the Premises related to the Tenant

Alterations such of the following as specified by Landlord: architectural plans and specifications, opinions from Landlord’s engineers stating that the Tenant Alterations will not in any way adversely affect the Building’s systems, necessary permits and licenses, certificates of insurance, and such other documents in such form reasonably requested by Landlord. Landlord may, in the exercise of reasonable judgment, request that Tenant provide Landlord with appropriate evidence of Tenant’s ability to complete and pay for the completion of the Tenant Alterations such as a performance bond or letter of credit. Upon completion of the Tenant Alterations, Tenant shall deliver to Landlord an as-built mylar and digitized (if available) set of plans and specifications for the Tenant Alterations.

(2) Tenant shall pay the cost of all Tenant Alterations and the cost of decorating the Premises and any work to the Property occasioned thereby. Upon completion of Tenant Alterations, Tenant shall furnish Landlord with contractors’ affidavits and full and final waivers of lien and receipted bills covering all labor and materials expended and used in connection therewith and such other documentation reasonably requested by Landlord or Mortgagee.

(3) Tenant agrees to complete all Tenant Alterations (i) in accordance with all Laws, Environmental Laws, all requirements of applicable insurance companies and in accordance with Landlord’s standard construction rules and regulations, and (ii) in a good and workmanlike manner with the use of good grades of materials. Tenant shall notify Landlord immediately if Tenant receives any notice of violation of any Law in connection with completion of any Tenant Alterations and shall immediately take such steps as are necessary to remedy such violation. In no event shall such supervision or right to supervise by Landlord nor shall any approvals given by Landlord under this Lease constitute any warranty by Landlord to Tenant of the adequacy of the design, workmanship or quality of such work or materials for Tenant’s intended use or of compliance with the requirements of Section 9.1(a)(3)(i) and (ii) above or impose any liability upon Landlord in connection with the performance of such work.

(b) All Tenant Additions whether installed by Landlord or Tenant, shall without compensation or credit to Tenant, become part of the Premises and the property of Landlord at the time of their installation and shall remain in the Premises, unless pursuant to Article Twelve, Tenant may remove them or is required to remove them at Landlord’s request. Landlord shall notify Tenant at the time of approval of Alterations if removal at the end of the Term is necessary.

9.2 LIENS

Tenant shall not permit any lien or claim for lien of any mechanic, laborer or supplier or any other lien to be filed against the Building, the Land, the Premises, or any other part of the Property arising out of work performed, or alleged to have been performed by, or at the direction of, or on behalf of Tenant. If any such lien or claim for lien is filed, Tenant shall within ten (10) days of receiving notice of such lien or claim (a) have such lien or claim for lien released of record or (b) deliver to Landlord a bond in form, content, amount, and issued by surety, satisfactory to Landlord, indemnifying, protecting, defending and holding harmless the Indemnitees against all costs and liabilities resulting from such lien or claim for lien and the foreclosure or attempted foreclosure thereof. If Tenant fails to take any of the above actions,

Landlord, in addition to its rights and remedies under Article Eleven, without investigating the validity of such lien or claim for lien, may pay or discharge the same and Tenant shall, as payment of additional Rent hereunder, reimburse Landlord upon demand for the amount so paid by Landlord, including Landlord’s expenses and attorneys’ fees.

ARTICLE 10

ASSIGNMENT AND SUBLETTING

10.1 ASSIGNMENT AND SUBLETTING

(a) Without the prior written consent of Landlord, which shall not be unreasonably withheld, Tenant may not sublease, assign, mortgage, pledge, hypothecate or otherwise transfer or permit the transfer of this Lease or the encumbering of Tenant’s interest therein in whole or in part, by operation of Law or otherwise or permit the use or occupancy of the Premises, or any part thereof, by anyone other than Tenant, provided, however, if Landlord chooses not to recapture the space proposed to be subleased or assigned as provided in Section 10.2, Landlord shall not unreasonably withhold its consent to a subletting or assignment under this Section 10.1. Tenant agrees that the provisions governing sublease and assignment set forth in this Article Ten shall be deemed to be reasonable. If Tenant desires to enter into any sublease of the Premises or assignment of this Lease, Tenant shall deliver written notice thereof to Landlord (“Tenant’s Notice”), together with the identity of the proposed subtenant or assignee and the proposed principal terms thereof and financial and other information sufficient for Landlord to make an informed judgment with respect to such proposed subtenant or assignee at least thirty (30) days prior to the commencement date of the term of the proposed sublease or assignment. If Tenant proposes to sublease less than all of the Rentable Area of the Premises, the space proposed to be sublet and the space retained by Tenant must each be a marketable unit as reasonably determined by Landlord and otherwise in compliance with all Laws. Landlord shall notify Tenant in writing of its approval or disapproval of the proposed sublease or assignment or its decision to exercise its rights under Section 10.2 within fifteen (15) days after receipt of Tenant’s Notice (and all required information). In no event may Tenant sublease any portion of the Premises or assign the Lease to any other tenant of the Project provided Landlord then has other space available in the Project. Tenant shall submit for Landlord’s approval (which approval shall not be unreasonably withheld) any advertising which Tenant or its agents intend to use with respect to the space proposed to be sublet.

(b) With respect to Landlord’s consent to an assignment or sublease, Landlord may take into consideration any factors that Landlord may deem relevant, and the reasons for which Landlord’s denial shall be deemed to be reasonable shall include, without limitation, the following:

(i) the business reputation or creditworthiness of any proposed subtenant or assignee is not acceptable to Landlord; or

(ii) in Landlord’s reasonable judgment the proposed assignee or sublessee would diminish the value or reputation of the Building or Landlord; or

(iii) any proposed assignee’s or sublessee’s use of the Premises would violate Section 7.1 of the Lease or would violate the provisions of any other leases of tenants in the Project; or

(iv) the proposed sublessee or assignee is a bona fide prospective tenant of Landlord in the Project and Landlord has sufficient space available to accommodate such prospective tenant’s needs, as demonstrated by a written proposal dated within ninety (90) days prior to the date of Tenant’s request; or

(v) the proposed sublessee or assignee would materially increase the estimated pedestrian and vehicular traffic to and from the Premises and the Building.

(c) Any sublease or assignment shall be expressly subject to the terms and conditions of this Lease. Any subtenant or assignee shall execute such documents as Landlord may reasonably require to evidence such subtenant or assignee’s assumption of the obligations and liabilities of Tenant under this Lease. Tenant shall deliver to Landlord a copy of all agreements executed by Tenant and the proposed subtenant and assignee with respect to the Premises. Landlord’s approval of a sublease, assignment, hypothecation, transfer or third party use or occupancy shall not constitute a waiver of Tenant’s obligation to obtain Landlord’s consent to further assignments or subleases, hypothecations, transfers or third party use or occupancy.

(d) So long as Tenant is not entering into a transaction described herein for the purpose of avoiding or otherwise circumventing the remaining terms of this Article, Tenant may, subject to Section 10.5, assign its entire interest under this Lease or Sublease all or a portion of the Premises, without the consent of Landlord, to (i) an Affiliate, or (ii) a successor to Tenant by purchase, merger, consolidation or reorganization, provided that all of the following conditions are satisfied: (1) Tenant is not in Default under this Lease; (2) Tenant shall give Landlord written notice at least thirty (30) days prior to the effective date of the proposed transfer together with the information required hereunder and such entity shall expressly assume Tenant’s obligations hereunder; (3) with respect to an assignment to an Affiliate, such Affiliate has a net worth equal to or greater than Tenant’s net worth at the date immediately prior to such transfer; and (4) with respect to a purchase, merger, consolidation or reorganization which results in Tenant ceasing to exist as a separate legal entity, Tenant’s successor shall have a net worth equal to Tenant’s net worth at the date immediately prior to such transfer.

10.2 RECAPTURE

Landlord shall have the option to exclude from the Premises covered by this Lease (“recapture”) the space proposed to be sublet or subject to the assignment, effective as of the proposed commencement date of such sublease or assignment. If Landlord elects to recapture, Tenant shall surrender possession of the space proposed to be subleased or subject to the assignment to Landlord on the effective date of recapture of such space from the Premises, such date being the Termination Date for such space. Effective as of the date of recapture of any portion of the Premises pursuant to this section, the Monthly Base Rent, Rentable Area of the Premises and Tenant’s Share shall be adjusted accordingly.

10.3 EXCESS RENT

Tenant shall pay Landlord on the first day of each month during the term of the sublease or assignment, fifty percent (50%) of the amount by which the sum of all rent due from the subtenant or assignee for such month exceeds: (i) that portion of the Monthly Base Rent and Rent Adjustments due under this Lease for said month which is allocable to the space sublet or assigned; and (ii) the following costs and expenses for the subletting or assignment of such space, amortized over the remaining term of the Lease: (1) brokerage commissions and attorneys’ fees and expenses, (2) the actual costs paid in making any improvements or substitutions in the Premises required by any sublease or assignment; and (3) “free rent” periods, costs of any inducements or concessions given to subtenant or assignee, moving costs, and other amounts in respect of such subtenant’s or assignee’s other leases or occupancy arrangements. All such costs and expenses shall be amortized over the term of the sublease or assignment pursuant to sound accounting principles.

10.4 TENANT LIABILITY

In the event of any sublease or assignment, whether or not with Landlord’s consent, Tenant shall not be released or discharged from any liability, whether past, present or future, under this Lease, including any liability arising from the exercise of any renewal or expansion option, to the extent such exercise is expressly permitted by Landlord. Tenant’s liability shall remain primary, and in the event of default by any subtenant, assignee or successor of Tenant in performance or observance of any of the covenants or conditions of this Lease, Landlord may proceed directly against Tenant without the necessity of exhausting remedies against said subtenant, assignee or successor. After any assignment, Landlord may consent to subsequent assignments or subletting of this Lease, or amendments or modifications of this Lease with assignees of Tenant, without notifying Tenant, or any successor of Tenant, and without obtaining its or their consent thereto, and such action shall not relieve Tenant or any successor of Tenant of liability under this Lease; provided that Landlord will not amend a sublease in a manner that will expand Tenant’s obligations hereunder. If Landlord grants consent to such sublease or assignment, Tenant shall pay all reasonable attorneys’ fees and expenses incurred by Landlord with respect to such assignment or sublease. In addition, if Tenant has any options to extend the Term or to add other space to the Premises, such options shall not be available to any subtenant or assignee, directly or indirectly without Landlord’s express written consent, which may be withheld in Landlord’s sole discretion.

10.5 ASSUMPTION AND ATTORNMENT

If Tenant shall assign this Lease as permitted herein, the assignee shall expressly assume all of the obligations of Tenant hereunder in a written instrument satisfactory to Landlord and furnished to Landlord not later than fifteen (15) days prior to the effective date of the assignment. If Tenant shall sublease the Premises as permitted herein, Tenant shall, at Landlord’s option, within fifteen (15) days following any request by Landlord, obtain and furnish to Landlord the written agreement of such subtenant to the effect that the subtenant will attorney to Landlord and will pay all subrent directly to Landlord.

ARTICLE 11

DEFAULT AND REMEDIES

11.1 EVENTS OF DEFAULT

The occurrence or existence of any one or more of the following shall constitute a “Default” by Tenant under this Lease:

(i) Tenant fails to pay any installment or other payment of Rent including Rent Adjustment Deposits or Rent Adjustments within ten (10) days after the date when due;

(ii) Tenant fails to observe or perform any of the other covenants, conditions or provisions of this Lease or the Workletter and fails to cure such default within thirty (30) days after written notice thereof to Tenant, unless the default involves a hazardous condition, which shall be cured forthwith or unless the failure to perform is a Default for which this Lease specifies there is no cure or grace period;

(iii) the interest of Tenant in this Lease is levied upon under execution or other legal process;

(iv) a petition is filed by or against Tenant to declare Tenant bankrupt or seeking a plan of reorganization or arrangement under any Chapter of the Bankruptcy Act, or any amendment, replacement or substitution therefor, or to delay payment of, reduce or modify Tenant’s debts, which in the case of an involuntary action is not discharged within thirty (30) days;

(v) Tenant is declared insolvent by Law or any assignment of Tenant’s property is made for the benefit of creditors;

(vi) a receiver is appointed for Tenant or Tenant’s property, which appointment is not discharged within thirty (30) days;

(vii) any action taken by or against Tenant to reorganize or modify Tenant’s capital structure in a materially adverse way which in the case of an involuntary action is not discharged within thirty (30) days;

(viii) upon the dissolution of Tenant; or

(ix) upon the third occurrence within any Lease Year that Tenant fails to pay Rent when due or has breached a particular covenant of this Lease (whether or not such failure or breach is thereafter cured within any stated cure or grace period or statutory period).

11.2 LANDLORD’S REMEDIES

(a) A Default shall constitute a breach of the Lease for which Landlord shall have the rights and remedies set forth in this Section 11.2 and all other rights and remedies set forth in this

Lease or now or hereafter allowed by Law, whether legal or equitable, and all rights and remedies of Landlord shall be cumulative and none shall exclude any other right or remedy.

(b) With respect to a Default, at any time Landlord may terminate Tenant’s right to possession by written notice to Tenant stating such election. Any written notice required pursuant to Section 11.1 shall constitute notice of unlawful detainer pursuant to California Code of Civil Procedure Section 1161 if, at Landlord’s sole discretion, it states Landlord’s election that Tenant’s right to possession is terminated after expiration of any period required by Law or any longer period required by Section 11.1. Upon the expiration of the period stated in Landlord’s written notice of termination (and unless such notice provides an option to cure within such period and Tenant cures the Default within such period), Tenant’s right to possession shall terminate and this Lease shall terminate, and Tenant shall remain liable as hereinafter provided. Upon such termination in writing of Tenant’s right to possession, Landlord shall have the right, subject to applicable Law, to re-enter the Premises and dispossess Tenant and the legal representatives of Tenant and all other occupants of the Premises by unlawful detainer or other summary proceedings, or otherwise as permitted by Law, regain possession of the Premises and remove their property (including their trade fixtures, personal property and those Tenant Additions which Tenant is required or permitted to remove under Article Twelve), but Landlord shall not be obligated to effect such removal, and such property may, at Landlord’s option, be stored elsewhere, sold or otherwise dealt with as permitted by Law, at the risk of, expense of and for the account of Tenant, and the proceeds of any sale shall be applied pursuant to Law. Landlord shall in no event be responsible for the value, preservation or safekeeping of any such property. Tenant hereby waives all claims for damages that may be caused by Landlord’s removing or storing Tenant’s personal property pursuant to this Section or Section 12.1, and Tenant hereby indemnifies, and agrees to defend, protect and hold harmless, the Indemnitees from any and all loss, claims, demands, actions, expenses, liability and cost (including attorneys’ fees and expenses) arising out of or in any way related to such removal or storage. Upon such written termination of Tenant’s right to possession and this Lease, Landlord shall have the right to recover damages for Tenant’s Default as provided herein or by Law, including the following damages provided by California Civil Code Section 1951.2:

(1) the worth at the time of award of the unpaid Rent which had been earned at the time of termination;

(2) 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 proves could reasonably have been avoided;

(3) the worth at the time of award of the amount by which the unpaid Rent for the balance of the term of this Lease after the time of award exceeds the amount of such Rent loss that Tenant proves could be reasonably avoided; and

(4) any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result therefrom, including, without limitation, Landlord’s unamortized costs of tenant improvements, leasing commissions and legal fees incurred in connection with entering into this Lease. The word “rent” as used in this Section

11.2 shall have the same meaning as the defined term Rent in this Lease. The “worth at the time of award” of the amount referred to in clauses (1) and (2) above is computed by allowing interest at the Default Rate. The worth at the time of award of the amount referred to in clause (3) above is computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one percent (1%). For the purpose of determining unpaid Rent under clause (3) above, the monthly Rent reserved in this Lease shall be deemed to be the sum of the Monthly Base Rent, monthly storage space rent, if any, and the amounts last payable by Tenant as Rent Adjustments for the calendar year in which Landlord terminated this Lease as provided hereinabove.

(c) Even if Tenant is in Default and/or has abandoned the Premises, this Lease shall continue in effect for so long as Landlord does not terminate Tenant’s right to possession by written notice as provided in Section 11.2(b) above, 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. In such event, Landlord shall have all of the rights and remedies of a landlord under California Civil Code Section 1951.4 (lessor may continue Lease in effect after Tenant’s Default and abandonment and recover Rent as it becomes due, if Tenant has the right to sublet or assign, subject only to reasonable limitations), or any successor statute. During such time as Tenant is in Default, if Landlord has not terminated this Lease by written notice and if Tenant requests Landlord’s consent to an assignment of this Lease or a sublease of the Premises, subject to Landlord’s option to recapture pursuant to Section 10.2, Landlord shall not unreasonably withhold its consent to such assignment or sublease. Tenant acknowledges and agrees that the provisions of Article Ten shall be deemed to constitute reasonable limitations of Tenant’s right to assign or sublet. Tenant acknowledges and agrees that in the absence of written notice pursuant to Section 11.2(b) above terminating Tenant’s right to possession, no other act of Landlord shall constitute a termination of Tenant’s right to possession or an acceptance of Tenant’s surrender of the Premises, including acts of maintenance or preservation or efforts to relet the Premises or the appointment of a receiver upon initiative of Landlord to protect Landlord’s interest under this Lease or the withholding of consent to a subletting or assignment, or terminating a subletting or assignment, if in accordance with other provisions of this Lease.

(d) In the event that Landlord seeks an injunction with respect to a breach or threatened breach by Tenant of any of the covenants, conditions or provisions of this Lease, Tenant agrees to pay the premium for any bond required in connection with such injunction.

(e) Tenant hereby waives any and all rights to relief from forfeiture, redemption or reinstatement granted by Law (including California Civil Code of Procedure Sections 1174 and 1179) in the event of Tenant being evicted or dispossessed for any cause or in the event of Landlord obtaining possession of the Premises by reason of Tenant’s Default or otherwise;

(f) Notwithstanding any other provision of this Lease, a notice to Tenant given under this Article and Article Twenty-four of this Lease or given pursuant to California Code of Civil Procedure Section 1161, and any notice served by mail shall be deemed served, and the requisite waiting period deemed to begin under said Code of Civil Procedure Section one business day after mailing by overnight courier service, without any additional waiting requirement under Code of Civil Procedure Section 1011 et seq. or by other Law. For purposes of Code of Civil Procedure Section 1162, Tenant’s “place of residence”, “usual place of business”, “the property”

and “the place where the property is situated” shall mean and be the Premises, whether or not Tenant has vacated same at the time of service.

(g) The voluntary or other surrender or termination of this Lease, or a mutual termination or cancellation thereof, shall not work a merger and shall terminate all or any existing assignments, subleases, subtenancies or occupancies permitted by Tenant, except if and as otherwise specified in writing by Landlord.

(h) No delay or omission in the exercise of any right or remedy of a party shall impair any right or remedy or be construed as a waiver. No provision of this Lease shall be deemed waived by a party unless such waiver is in writing signed by the party waiving such provision. The waiver of any breach of any provision of this Lease shall not be deemed a waiver of any subsequent breach of the same or any other provision of this Lease.

11.3 ATTORNEY’S FEES

In the event any party brings any suit or other proceeding with respect to the subject matter or enforcement of this Lease, the prevailing party (as determined by the court, agency or other authority before which such suit or proceeding is commenced) shall, in addition to such other relief as may be awarded, be entitled to recover attorneys’ fees, expenses and costs of investigation as actually incurred, including court costs, expert witness fees, costs and expenses of investigation, and all attorneys’ fees, costs and expenses in any such suit or proceeding (including in any action or participation in or in connection with any case or proceeding under the Bankruptcy Code, 11 United States Code Sections 101 et seq., or any successor statutes, in establishing or enforcing the right to indemnification, in appellate proceedings, or in connection with the enforcement or collection of any judgment obtained in any such suit or proceeding).

11.4 BANKRUPTCY

The following provisions shall apply in the event of the bankruptcy or insolvency of Tenant:

(a) In connection with any proceeding under Chapter 7 of the Bankruptcy Code where the trustee of Tenant elects to assume this Lease for the purposes of assigning it, such election or assignment, may only be made upon compliance with the provisions of (b) and (c) below, which conditions Landlord and Tenant acknowledge to be commercially reasonable. In the event the trustee elects to reject this Lease then Landlord shall immediately be entitled to possession of the Premises without further obligation to Tenant or the trustee.

(b) Any election to assume this Lease under Chapter 11 or 13 of the Bankruptcy Code by Tenant as debtor-in-possession or by Tenant’s trustee (the “Electing Party”) must provide for:

The Electing Party to cure or provide to Landlord adequate assurance that it will cure all monetary defaults under this Lease within fifteen (15) days from the date of assumption and it will cure all nonmonetary defaults under this Lease within thirty (30) days from the date of assumption. Landlord and Tenant acknowledge such condition to be commercially reasonable.

(c) If the Electing Party has assumed this Lease or elects to assign Tenant’s interest under this Lease to any other person, such interest may be assigned only if the intended assignee has provided adequate assurance of future performance (as herein defined), of all of the obligations imposed on Tenant under this Lease.

For the purposes hereof, “adequate assurance of future performance” means that Landlord has ascertained that each of the following conditions has been satisfied:

(i) The assignee has submitted a current financial statement, certified by its chief financial officer, which shows a net worth and working capital in amounts sufficient to assure the future performance by the assignee of Tenant’s obligations under this Lease; and

(ii) Landlord has obtained consents or waivers from any third parties that may be required under a lease, mortgage, financing arrangement, or other agreement by which Landlord is bound, to enable Landlord to permit such assignment.

(d) Landlord’s acceptance of rent or any other payment from any trustee, receiver, assignee, person, or other entity will not be deemed to have waived, or waive, the requirement of Landlord’s consent, Landlord’s right to terminate this Lease for any transfer of Tenant’s interest under this Lease without such consent, or Landlord’s claim for any amount of Rent due from Tenant.

11.5 LANDLORD’S DEFAULT

Landlord shall be in default hereunder in the event Landlord has not begun and pursued with reasonable diligence the cure of any failure of Landlord to meet its obligations hereunder within thirty (30) days after the receipt by Landlord of written notice from Tenant of the alleged failure to perform. In no event shall Tenant have the right to terminate or rescind this Lease as a result of Landlord’s default as to any covenant or agreement contained in this Lease. Tenant hereby waives such remedies of termination and rescission and hereby agrees that Tenant’s remedies for default hereunder and for breach of any promise or inducement shall be limited to a suit for damages and/or injunction. In addition, Tenant hereby covenants that, prior to the exercise of any such remedies, it will give the Mortgagee notice and a reasonable time to cure any default by Landlord.

ARTICLE 12

SURRENDER OF PREMISES

12.1 IN GENERAL

Upon the Termination Date, Tenant shall surrender and vacate the Premises immediately and deliver possession thereof to Landlord in a clean, good and tenantable condition, ordinary wear and tear, casualty damage and damage caused by Landlord excepted. Tenant shall deliver to Landlord all keys to the Premises. 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 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. If any of the Tenant Additions which were installed by Tenant involved the lowering of ceilings, raising of floors or the installation of specialized wall or floor coverings or lights, then Tenant shall also be obligated to return such surfaces to their condition prior to the commencement of this Lease. Tenant shall also be required to close any staircases or other openings between floors. In the event possession of the Premises is not delivered to Landlord when required hereunder, or if Tenant shall fail to remove those items described above, Landlord may (but shall not be obligated to), at Tenant’s expense, remove any of such property and store, sell or otherwise deal with such property, and undertake, at Tenant’s expense, such restoration work as Landlord deems necessary or advisable.

12.2 LANDLORD’S RIGHTS

All property which may be removed from the Premises by Landlord shall be conclusively presumed to have been abandoned by Tenant and Landlord may deal with such property as provided in Section 11.2(b), including the waiver and indemnity obligations provided in that Section.

ARTICLE 13

HOLDING OVER

In the event that Tenant holds over in possession of the Premises after the Termination Date, Tenant shall pay Landlord 125% of the monthly Rent payable for the month immediately preceding the holding over (including increases for Rent Adjustments which Landlord may reasonably estimate. Tenant shall also pay all damages sustained by Landlord by reason of such retention of possession. The provisions of this Article shall not constitute a waiver by Landlord of any re-entry rights of Landlord and Tenant’s continued occupancy of the Premises shall be as a tenancy in sufferance.

ARTICLE 14

DAMAGE BY FIRE OR OTHER CASUALTY

14.1 SUBSTANTIAL UNTENANTABILITY

(a) If any fire or other casualty (whether insured or uninsured) renders all or a substantial portion of the Premises or the Building untenantable, Landlord shall, with reasonable promptness after the occurrence of such damage, estimate the length of time that will be required to substantially complete the repair and restoration and shall by notice advise Tenant of such estimate (“Landlord’s Notice”). If Landlord estimates that the amount of time required to substantially complete such repair and restoration will exceed one hundred eighty (180) days from the date such damage occurred, then Landlord, or Tenant if all or a substantial portion of the Premises is rendered untenantable, shall have the right to terminate this Lease as of the date of such damage upon giving written notice to the other at any time within twenty (20) days after delivery of Landlord’s Notice, provided that if Landlord so chooses, Landlord’s Notice may also constitute such notice of termination.

(b) Unless this Lease is terminated as provided in the preceding subparagraph, Landlord shall proceed with reasonable promptness to repair and restore the Premises to its condition as existed prior to such casualty, subject to reasonable delays for insurance adjustments and Force Majeure delays, and also subject to zoning Laws and building codes then in effect. Landlord shall have no liability to Tenant, and Tenant shall not be entitled to terminate this Lease if such repairs and restoration are not in fact completed within the time period estimated by Landlord so long as Landlord shall proceed with reasonable diligence to complete such repairs and restoration.

(c) Tenant acknowledges that Landlord shall be entitled to the full proceeds of any insurance coverage, whether carried by Landlord or Tenant, for damages to the Premises, except for those proceeds of Tenant’s insurance of its own personal property and equipment which would be removable by Tenant at the Termination Date. All such insurance proceeds shall be payable to Landlord whether or not the Premises are to be repaired and restored, provided, however, if this Lease is not terminated and the parties proceed to repair and restore Tenant Additions at Tenant’s cost, to the extent Landlord received proceeds of Tenant’s insurance covering Tenant Additions, such proceeds shall be applied to reimburse Tenant for its cost of repairing and restoring Tenant Additions.

(d) Notwithstanding anything to the contrary herein set forth: (i) Landlord shall have no duty pursuant to this Section to repair or restore any portion of any Tenant Additions or to expend for any repair or restoration of the Premises or Building amounts in excess of insurance proceeds paid to Landlord and available for repair or restoration; and (ii) Tenant shall not have the right to terminate this Lease pursuant to this Section if any damage or destruction was caused by the act or neglect of Tenant, its agent or employees. Whether or not the Lease is terminated pursuant to this Article Fourteen, in no event shall Tenant be entitled to any compensation or damages for loss of the use of the whole or any part of the Premises or for any inconvenience or annoyance occasioned by any such damage, destruction, rebuilding or restoration of the Premises or the Building or access thereto.

(e) Any repair or restoration of the Premises performed by Tenant shall be in accordance with the provisions of Article Nine hereof.

14.2 INSUBSTANTIAL UNTENANTABILITY

If the Premises or the Building is damaged by a casualty but neither is rendered substantially untenantable and Landlord estimates that the time to substantially complete the repair or restoration will not exceed one hundred eighty (180) days from the date such damage occurred, then Landlord shall proceed to repair and restore the Building or the Premises other than Tenant Additions, with reasonable promptness, unless such damage is to the Premises and occurs during the last six (6) months of the Term, in which event either Tenant or Landlord shall have the right to terminate this Lease as of the date of such casualty by giving written notice thereof to the other within twenty (20) days after the date of such casualty. Notwithstanding the aforesaid, Landlord’s obligation to repair shall be limited in accordance with the provisions of Section 14.1 above.

14.3 RENT ABATEMENT

Except for the negligence or willful act of Tenant or its agents, employees, contractors or invitees, if all or any part of the Premises are rendered untenantable by fire or other casualty and this Lease is not terminated, Monthly Base Rent and Rent Adjustments shall abate for that part of the Premises which is untenantable on a per diem basis based upon both percentage of space and type of use of such uninhabitable space from the date of the casualty until Landlord has Substantially Completed the repair and restoration work in the Premises which it is required to perform, provided, that as a result of such casualty, Tenant does not occupy the portion of the Premises which is untenantable during such period.

14.4 WAIVER OF STATUTORY REMEDIES

The provisions of this Lease, including this Article Fourteen, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, the Premises or the Property or any part of either, and any Law, including Sections 1932(2), 1933(4), 1941 and 1942 of the California Civil Code, with respect to any rights or obligations concerning damage or destruction shall have no application to this Lease or to any damage to or destruction of all or any part of the Premises or the Property or any part of either, and are hereby waived.

ARTICLE 15

EMINENT DOMAIN

15.1 TAKING OF WHOLE OR SUBSTANTIAL PART

In the event the whole or any substantial part of the Building or of the Premises is taken or condemned by any competent authority for any public use or purpose (including a deed given in lieu of condemnation) and is thereby rendered untenantable, this Lease shall terminate as of the date title vests in such authority, and Monthly Base Rent and Rent Adjustments shall be apportioned as of the Termination Date. Notwithstanding anything to the contrary herein set

forth, in the event the taking is temporary (for less than the remaining Term of the Lease), Landlord may elect either (i) to terminate this Lease or (ii) permit Tenant to receive the entire award attributable to the Premises in which case Tenant shall continue to pay Rent and this Lease shall not terminate.

15.2 TAKING OF PART

In the event a part of the Building or the Premises is taken or condemned by any competent authority (or a deed is delivered in lieu of condemnation) and this Lease is not terminated, the Lease shall be amended to reduce or increase, as the case may be, the Monthly Base Rent and Tenant’s Share to reflect the Rentable Area of the Premises or Building, as the case may be, remaining after any such taking or condemnation. Landlord, upon receipt and to the extent of the award in condemnation (or proceeds of sale) shall make necessary repairs and restorations to the Premises (exclusive of Tenant Additions) and to the Building to the extent necessary to constitute the portion of the Building not so taken or condemned as a complete architectural and economically efficient unit. Notwithstanding the foregoing, if as a result of any taking, or a governmental order that the grade of any street or alley adjacent to the Building is to be changed and such taking or change of grade makes it necessary or desirable to substantially remodel or restore the Building or prevents the economical operation of the Building, Landlord shall have the right to terminate this Lease upon ninety (90) days prior written notice to Tenant.

15.3 COMPENSATION

Landlord shall be entitled to receive the entire award (or sale proceeds) from any such taking, condemnation or sale without any payment to Tenant, and Tenant hereby assigns to Landlord Tenant’s interest, if any, in such award; provided, however, Tenant shall have the right separately to pursue against the condemning authority a separate award in respect of the loss, if any, to Tenant Additions paid for by Tenant without any credit or allowance from Landlord so long as there is no diminution of Landlord’s award as a result.

ARTICLE 16

(c) Provided that Landlord’s right of full recovery under its policy or policies aforesaid is not adversely affected or prejudiced thereby, Landlord hereby waives any and all right of recovery which it might otherwise have against Tenant, its servants, agents and employees, for loss or damage occurring to the Real Property and the fixtures, appurtenances and equipment therein, to the extent the same is covered by Landlord’s insurance, notwithstanding that such loss or damage may result from the negligence or fault of Tenant, its servants, agents or employees. Provided that Tenant’s right of full recovery under its aforesaid policy or policies is not adversely affected or prejudiced thereby, Tenant hereby waives any and all right of recovery which it might otherwise have against Landlord, its servants, and employees and against every other tenant of the Real Property who shall have executed a similar waiver as set forth in this Section 16.4 (c) for loss or damage to Tenant Additions, whether or not removable, and to Tenant’s furniture, furnishings, fixtures and other property removable by Tenant under the provisions hereof to the extent the same is coverable by Tenant’s insurance required under this Lease, notwithstanding that such loss or damage may result from the negligence or fault of Landlord, its servants, agents or employees, or such other tenant and the servants, agents or employees thereof.

(d) Landlord and Tenant hereby agree to advise the other promptly if the clauses to be included in their respective insurance policies pursuant to subparagraphs (a) and (b) above cannot be obtained on the terms hereinbefore provided and thereafter to furnish the other with a certificate of insurance or copy of such policies showing the naming of the other as an additional insured, as aforesaid. Landlord and Tenant hereby also agree to notify the other promptly of any cancellation or change of the terms of any such policy that would affect such clauses or naming.

obtainable, contain agreements by the insurers to the effect that no act or omission of any additional insured will invalidate the policy as to the other additional insureds.

WAIVER OF CLAIMS AND INDEMNITY

17.1 WAIVER OF CLAIMS

To the extent permitted by Law, Tenant releases the Indemnitees from, and waives all claims for, damage to person or property sustained by the Tenant or any occupant of the Premises or the Property resulting directly or indirectly from any existing or future condition, defect, matter or thing in and about the Premises or the Property or any part of either or any equipment or appurtenance therein, or resulting from any accident in or about the Premises or the Property, or resulting directly or indirectly from any act or neglect of any tenant or occupant of the Property or of any other person, including Landlord’s agents and servants, except to the extent caused by the gross negligence or willful and wrongful act of any of the Indemnitees. To the extent permitted by Law, Tenant hereby waives any consequential damages, compensation or claims for inconvenience or loss of business, rents, or profits as a result of such injury or damage, whether or not caused by the gross negligence or willful and wrongful act of any of the Indemnitees. If any such damage, whether to the Premises or the Property or any part of either, or whether to Landlord or to other tenants in the Property, results from any act or neglect of Tenant, its employees, servants, agents, contractors, invitees or customers, Tenant shall be liable therefor and Landlord may, at Landlord’s option, repair such damage and Tenant shall, upon demand by Landlord, as payment of additional Rent hereunder, reimburse Landlord within ten (10) days of demand for the total cost of such repairs, in excess of amounts, if any, paid to Landlord under insurance covering such damages. Tenant shall not be liable for any such damage caused by its acts or neglect if Landlord or a tenant has recovered the full amount of the damage from proceeds of insurance policies and the insurance company has waived its right of subrogation against Tenant.

17.2 INDEMNITY BY TENANT

To the extent permitted by Law, Tenant hereby indemnifies, and agrees to protect, defend and hold the Indemnitees harmless, against any and all actions, claims, demands, liability, costs and expenses, including attorneys’ fees and expenses for the defense thereof, arising from Tenant’s occupancy of the Premises, from the undertaking of any Tenant Additions or repairs to the Premises, from the conduct of Tenant’s business on the Premises, or from any breach or default on the part of Tenant in the performance of any covenant or agreement on the part of Tenant to be performed pursuant to the terms of this Lease, or from any willful act or negligence of Tenant, its agents, contractors, servants, employees, customers or invitees, in or about the Premises or the Property or any part of either. In case of any action or proceeding brought

against the Indemnitees by reason of any such claim, upon notice from Landlord, Tenant covenants to defend such action or proceeding by counsel chosen by Landlord, in Landlord’s sole discretion. Landlord reserves the right to settle, compromise or dispose of any and all actions, claims and demands related to the foregoing indemnity. The foregoing indemnity shall not operate to relieve Indemnitees of liability to the extent such liability is caused by the willful and wrongful act of Indemnitees. Further, the foregoing indemnity is subject to and shall not diminish any waivers in effect in accordance with Section 16.4 by Landlord or its insurers to the extent of amounts, if any, paid to Landlord under its “All-Risks” property insurance. Notwithstanding the foregoing, Landlord hereby indemnifies, and agrees to protect, defend and hold Tenant harmless, against any and all damages and losses, including attorneys’ fees and expenses for the defense thereof, arising out of Landlord’s gross negligence or willful misconduct.

MORTGAGEE PROTECTION

23.1 SUBORDINATION AND ATTORNMENT

This Lease is and shall be expressly subject and subordinate at all times to (i) any ground or underlying lease of the Real Property, now or hereafter existing, and all amendments, extensions, renewals and modifications to any such lease, and (ii) the lien of any mortgage or trust deed now or hereafter encumbering fee title to the Real Property and/or the leasehold estate under any such lease, and all amendments, extensions, renewals, replacements and modifications of such mortgage or trust deed and/or the obligation secured thereby, unless such ground lease or ground lessor, or mortgage, trust deed or Mortgagee, expressly provides or elects that the Lease shall be superior to such lease or mortgage or trust deed. If any such mortgage or trust deed is foreclosed (including any sale of the Real Property pursuant to a power of sale), or if any such lease is terminated, upon request of the Mortgagee or ground lessor, as the case may be, Tenant shall attorney to the purchaser at the foreclosure sale or to the ground lessor under such lease, as

the case may be, provided, however, that such purchaser or ground lessor shall not be (i) bound by any payment of Rent for more than one month in advance except payments in the nature of security for the performance by Tenant of its obligations under this Lease; (ii) subject to any offset, defense or damages arising out of a default of any obligations of any preceding Landlord; or (iii) bound by any amendment or modification of this Lease made without the written consent of the Mortgagee or ground lessor; or (iv) liable for any security deposits not actually received in cash by such purchaser or ground lessor. Tenant shall execute and deliver reasonable instruments confirming the attornment provided for herein. Notwithstanding the self-operative subordination, non-disturbance and attornment provided in this Lease, within ten (10) days after Landlord’s written request therefor, Tenant shall execute any and all documents required by Landlord, or any Mortgagee evidencing this Lease to be subordinate to the lien of any such lease, mortgage or deed of trust, as the case may be provided that such document grants Tenant non-disturbance under such entity’s then customary form and recognizes Tenant’s rights hereunder. Tenant appoints Landlord as Tenant’s attorney-in-fact to execute such documents on behalf of Tenant if Tenant does not do so.

23.2 MORTGAGEE PROTECTION

Tenant agrees to give any Mortgagee or ground lessor, by registered or certified mail, a copy of any notice of default served upon the Landlord by Tenant, provided that prior to such notice Tenant has received notice (by way of service on Tenant of a copy of an assignment of rents and leases, or otherwise) of the address of such Mortgagee or ground lessor. Tenant further agrees that if Landlord shall have failed to cure such default within the time provided for in this Lease, then the Mortgagee or ground lessor shall have an additional thirty (30) days after receipt of notice thereof within which to cure such default or if such default cannot be cured within that time, then such additional notice time as may be necessary, if, within such thirty (30) days, any Mortgagee or ground lessor has commenced and is diligently pursuing the remedies necessary to cure such default (including commencement of foreclosure proceedings or other proceedings to acquire possession of the Real Property, if necessary to effect such cure). Such period of time shall be extended by any period within which such Mortgagee or ground lessor is prevented from commencing or pursuing such foreclosure proceedings or other proceedings to acquire possession of the Real Property by reason of Landlord’s bankruptcy. Until the time allowed as aforesaid for Mortgagee or ground lessor to cure such defaults has expired without cure, Tenant shall have no right to, and shall not, terminate this Lease on account of default.

ARTICLE 24

NOTICES

(a) All notices, demands or requests provided for or permitted to be given pursuant to this Lease must be in writing and shall be personally delivered, sent by Federal Express or other

reputable overnight courier service, or mailed by first class, registered or certified United States mail, return receipt requested, postage prepaid.

(b) All notices, demands or requests to be sent pursuant to this Lease shall be deemed to have been properly given or served by delivering or sending the same in accordance with this Section, addressed to the parties hereto at their respective addresses listed in Sections 1.1.

(c) The time period in which a response to any such notice, demand or request must be given shall commence to run from (i) in the case of delivery by mail, the date of receipt on the return receipt of the notice, demand or request by the addressee thereof, or (ii) in the case of delivery by Federal Express or other overnight courier service, the date of acceptance of delivery by an employee, officer, director or partner of Landlord or Tenant. Rejection or other refusal to accept or the inability to deliver because of changed address of which no notice was given, as indicated by advice from Federal Express or other overnight courier service or by mail return receipt, shall be deemed to be receipt of notice, demand or request sent. Notices may also be served by personal service upon any officer, director or partner of Landlord or Tenant, and shall be effective upon such service.

(d) By giving to the other party at least thirty (30) days written notice thereof, either party shall have the right from time to time during the term of this Lease to change their respective addresses for notices, statements, demands and requests, provided such new address shall be within the United States of America.

ARTICLE 25

MISCELLANEOUS

25.1 LATE CHARGES

(a) All payments required hereunder (other than the Monthly Base Rent, Rent Adjustments, and Rent Adjustment Deposits, which shall be due as hereinbefore provided) to Landlord shall be paid within ten (10) days after Landlord’s demand therefor. All such amounts (including Monthly Base Rent, Rent Adjustments, and Rent Adjustment Deposits) not paid when due shall bear interest from the date due until the date paid at the Default Rate in effect on the date such payment was due.

(b) In the event Tenant is more than ten (10) days late in paying any installment of Rent due under this Lease, Tenant shall pay Landlord a late charge equal to five percent (5%) of the delinquent installment of Rent. The parties agree that (i) such delinquency will cause Landlord to incur costs and expenses not contemplated herein, the exact amount of which will be difficult to calculate, including the cost and expense that will be incurred by Landlord in processing each delinquent payment of rent by Tenant, (b) the amount of such late charge represents a reasonable estimate of such costs and expenses and that such late charge shall be paid to Landlord for each delinquent payment in addition to all Rent otherwise due hereunder. The parties further agree that the payment of late charges and the payment of interest provided for in subparagraph (a) above are distinct and separate from one another in that the payment of interest is to compensate Landlord for its inability to use the money improperly withheld by

Tenant, while the payment of late charges is to compensate Landlord for its additional administrative expenses in handling and processing delinquent payments.

(c) Payment of interest at the Default Rate and/or of late charges shall not excuse or cure any default by Tenant under this Lease, nor shall the foregoing provisions of this Article or any such payments prevent Landlord from exercising any right or remedy available to Landlord upon Tenant’s failure to pay Rent when due, including the right to terminate this Lease.

25.2 NO JURY TRIAL; VENUE; JURISDICTION

Each party hereto (which includes any assignee, successor, heir or personal representative of a party) shall not seek a jury trial, hereby waives trial by jury, and hereby further waives any objection to venue in the County in which the Project is located, and agrees and consents to personal jurisdiction of the courts of the State of California, in any action or proceeding or counterclaim brought by any party hereto against the other on any matter whatsoever arising out of or in any way connected with this Lease, the relationship of Landlord and Tenant, Tenant’s use or occupancy of the Premises, or any claim of injury or damage, or the enforcement of any remedy under any statute, emergency or otherwise, whether any of the foregoing is based on this Lease or on tort law. No party will seek to consolidate any such action in which a jury has been waived with any other action in which a jury trial cannot or has not been waived. It is the intention of the parties that these provisions shall be subject to no exceptions. By execution of this Lease the parties agree that this provision may be filed by any party hereto with the clerk or judge before whom any action is instituted, which filing shall constitute the written consent to a waiver of jury trial pursuant to and in accordance with Section 631 of the California Code of Civil Procedure. No party has in any way agreed with or represented to any other party that the provisions of this Section will not be fully enforced in all instances. The provisions of this Section shall survive the expiration or earlier termination of this Lease.

25.4 OPTION

This Lease shall not become effective as a lease or otherwise until executed and delivered by both Landlord and Tenant. The submission of the Lease to Tenant does not constitute a reservation of or option for the Premises, but when executed by Tenant and delivered to Landlord, the Lease shall constitute an irrevocable offer by Tenant in effect for five (5) days to lease the Premises on the terms and conditions herein contained.

25.5 TENANT AUTHORITY

Tenant represents and warrants to Landlord that it has full authority and power to enter into and perform its obligations under this Lease, that the person executing this Lease is fully empowered to do so, and that no consent or authorization is necessary from any third party.

25.7 MODIFICATION OF LEASE FOR BENEFIT OF MORTGAGEE

Tenant agrees, on its behalf and on behalf of its successors and assigns, that any liability or obligation under this Lease shall only be enforced against Landlord’s equity interest in the Property up to a maximum of Five Million Dollars ($5,000,000.00) and in no event against any other assets of the Landlord, or Landlord’s officers or directors or partners, and that any liability of Landlord with respect to this Lease shall be so limited and Tenant shall not be entitled to any judgment in excess of such amount.

25.9 ACCORD AND SATISFACTION

No payment by Tenant or receipt by Landlord of a lesser amount than any installment or payment of Rent due shall be deemed to be other than on account of the amount due, and no endorsement or statement on any check or any letter accompanying any check or payment of Rent shall be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such installment or payment of Rent or pursue any other remedies available to Landlord. No receipt of money by Landlord from Tenant after the termination of this Lease or Tenant’s right of possession of the Premises shall reinstate, continue or extend the Term. Receipt or acceptance of payment from anyone other than Tenant, including an assignee of Tenant, is not a waiver of any breach of Article Ten, and Landlord may accept such payment on account of the amount due without prejudice to Landlord’s right to pursue any remedies available to Landlord.

25.10 LANDLORD’S OBLIGATIONS ON SALE OF BUILDING

In the event of any sale or other transfer of the Building, Landlord shall be entirely freed and relieved of all agreements and obligations of Landlord hereunder accruing or to be performed after the date of such sale or transfer, and any remaining liability of Landlord with respect to this Lease shall be limited to the dollar amount specified in Section 25.08 and Tenant shall not be entitled to any judgment in excess of such amount. Landlord shall have the right to assign this Lease to an entity comprised of the principals of Landlord or affiliates of such entities. Upon such assignment and assumption of the obligations of Landlord hereunder, Landlord shall be entirely freed and relieved of all obligations hereunder.

If Tenant approves such written estimate and if such cost is in excess of Landlord’s estimate of the Turn-key Construction Costs, Tenant shall accompany such approval with a good check made payable to the order of Landlord in the amount of the estimated cost of preparing the Change Order and performing the work thereto, and the foregoing shall constitute Landlord’s authorization to proceed. If such written authorization, and check if required, are not received by Landlord within such three (3) business day period, Landlord shall not be obligated to prepare the Change Order or perform any work in connection therewith.

5. Tenant Delay. If the Substantial Completion of the Tenant Improvements in the Premises is delayed due to Tenant Delay (defined in the Lease), then Tenant shall be responsible for all costs and any expenses occasioned by such delay, including any costs and expenses attributable to increases in labor or materials, and the provisions of Article Two of the Lease shall apply.

6. Entry by Tenant. Tenant may, with Landlord’s written consent, which will not unreasonably be withheld, enter the Premises during construction and prior to the Commencement Date for the Premises solely for the purpose of installing Tenant’s Personal Property (defined in Section 3.2 above) as long as such entry will not interfere with the timely and orderly construction and completion of the Premises. Tenant shall notify Landlord of its desired time(s) of entry and shall submit for Landlord’s approval the scope of the work to be performed and the name(s) of the contractor(s) who will perform such work. Such work and such contractors shall be subject to Landlord’s approval in the same manner as for work subject to Section 9.01(a) of the Lease. Such entry shall be without payment of Base Monthly Rent or Rent Adjustments, but such entry and all acts and omissions in connection with it are subject to and governed by all other provisions of the Lease, including Tenant’s indemnification obligations, insurance obligations, obligations under Article Seven and the provisions of Section 9.02.

7. Force and Effect. The terms and conditions of this Workletter supplement the Lease and shall be construed to be a part of the Lease and are incorporated in the Lease. Without limiting the generality of the foregoing, any default by any party hereunder shall have the same force and effect as a default under the Lease. Should any inconsistency arise between this Workletter and the Lease as to the specific matters that are the subject of this Workletter, the terms and conditions of this Workletter shall control.

SECOND AMENDMENT

LEASE BETWEEN

EMERY STATION ASSOCIATES II, LLC (LANDLORD)

And

NOVACAL PHARMACEUTICALS, INC. (TENANT)

EMERYSTATION NORTH PROJECT

Emeryville, California

Reference is made to that certain Lease dated June 3, 2004 by and between Emery Station Associates II, LLC, as Landlord, and NovaCal Pharmaceuticals, Inc., as Tenant, as such Lease was amended via First Amendment executed by Landlord June 22, 2004 (together, the “Lease”). The Lease is further amended by this Second Amendment dated July 22, 2004, as follows:

I.	Tenant has requested to occupy space temporarily on the 5^th floor of EmeryStation North in advance of substantial completion of the Landlord’s Work for Tenant’s permanent Premises described in the Lease.

II.

Commencing July 30, 2004, Tenant shall be able to occupy the space delineated on the attached Exhibit A hereto (the “Temporary Space”) and shall be able to use such space for office space, storage and for limited lab purposes. Tenant’s use and occupancy of the Temporary Space will be subject to all the same terms and conditions of Tenant’s base Lease except for the rent paid for the Temporary Space, which is specified herein. Tenant agrees to accept the Temporary Space on an as-is basis.

III.

Tenant’s occupancy of the Temporary Space shall be deemed a month-to-month tenancy, cancelable at any time by either party with written notice, except that Landlord agrees that, so long as Tenant is not in default under its Lease (as amended by the First and Second Amendments), it will extend the month-to-month tenancy until such time as the substantial completion of the Landlord’s Work for Tenant’s permanent Premises, (or at the point Landlord’s Work would have been completed absent any Tenant Delay and/or Tenant default).

IV.

Tenant agrees to vacate the Temporary Space upon substantial completion of Landlord Work in the permanent Premises (or at the point Landlord’s Work would have been completed absent any Tenant Delay and/or Tenant default). Immediately upon its vacation Tenant agrees to restore the Temporary Space to the same condition when it assumed initial occupancy, including any decontamination of the lab area(s) to such reasonable standards that Landlord may require. If tenant fails to do so, landlord can do so on Tenant’s behalf and bill tenant for the cost thereof. Tenant’s obligation to pay rent for the temporary Space shall continue until the aforementioned restoration and decontamination of the Temporary Space are complete.

Tenant shall pay rent for the Temporary Space in the amount of $7,500 per month, payable in advance. Rent for the first month shall be paid upon execution of this Second Lease Amendment. This rental rate assumes a reasonable amount of electrical consumption based on the understanding that Tenant’s lab operations in the Temporary Space (if any) will not be extensive. If this does not prove to be the case, Landlord reserves the right to adjust the monthly rent a reasonable amount to reflect the excessive power utilization by Tenant. In addition, Tenant may rent a reasonable number of parking spaces at Landlord’s quoted rates during its temporary occupancy period.

VI.

Tenant acknowledges that the Temporary Space is part of a larger suite, that the Temporary Space will not be formally demised from the balance of that suite, that Landlord may allow other tenant(s) to occupy the balance of that suite and/or Landlord can show both the Temporary Space and the balance of the suite to prospective tenants during Tenant’s occupancy of the Temporary Space.

III.	Except for those terms outlined above, all other terms and conditions of the base Lease and WorkLetter and Exhibits (as amended by the First Amendment) shall apply.

In witness hereof, the parties have executed this Second Amendment as of the date noted below.

FOURTH AMENDMENT

LEASE BETWEEN

EMERY STATION OFFICE II, LLC (LANDLORD)

And

NOVACAL PHARMACEUTICALS, INC. (TENANT)

EMERYSTATION NORTH PROJECT

Emeryville, California

That certain lease dated June 3, 2004, by and between Emery Station Office II, LLC, a California Limited Liability Company, as Landlord (“Landlord”), and Novacal Pharmaceuticals, Inc., a California Corporation, as Tenant (“Tenant”), a such lease was amended by First Amendment dated June 22, 2004, by Second Amendment dated July 22, 2004 and by Third Amendment dated March 25, 2005 (collectively, the “Lease”), is hereby further amended as outlined below. The effective date of this Fourth Amendment shall be September 30, 2006 (the “Fourth Amendment Effective Date”). From and after the Fourth Amendment Effective Date the Lease and this Fourth Amendment thereto shall be referred to as the “Lease” for all purposes.

PREMISES:

Tenant has requested to lease from Landlord and Landlord has agreed to lease to Tenant (under the terms enumerated herein) the following additional spaces in the EmeryStation North building:

Suite 395, which is presently leased to Wareham Property Group, an affiliate of Landlord. This suite measures 325 rentable square feet, and can be used as storage space.

Suite 575, which is presently leased to H2Volt. This suite measures 2,248 rentable square feet and can be used as office and lab space.

Suite 580, which is presently leased to Eureka Pharmaceuticals. This suite measures 957 rentable square feet and can be used as office and lab space.

All of the above spaces are more specifically described on Exhibit A attached hereto.

II.	COMMENCEMENT:

Tenant acknowledges and understands that all three suites are presently leased to others. The lease term and rent applicable to each suite will commence upon the delivery of each specific suite by Landlord to Tenant, as more fully described below:

Suite 395: Landlord will cause the existing tenant of Suite 395 to vacate as quickly as is commercially reasonable, and will deliver the space to Tenant. That date shall be referred to as the “Suite 395 Commencement Date”.

Suite 575: Suite 575 is occupied by H2Volt under a lease that is terminable by Landlord with 30-days notice, such notice requiring delivery at the beginning of a calendar month. Landlord agrees to give H2Volt such 30-day notice on the first day of the month immediately following the Fourth Amendment Effective Date. As detailed in Section 2.3 of the Lease, Landlord shall not be liable for any delay in being able to deliver the space for any reason including but not limited to H2Volt’s unauthorized holdover in the space. Landlord agrees to use commercially-reasonable efforts to cause H2Volt to vacate the space per the terms of its

lease. Upon termination of H2Volt’s lease and their vacation of the space, Landlord will deliver Suite 575 to Tenant, such date being referred to as the “Suite 575 Commencement Date”.

Suite 580: Tenant agrees to lease Suite 580 as soon as the existing lease with Eureka Pharmaceuticals (“Eureka”) terminates and Eureka vacates the space. Suite 580 is presently under lease to Eureka through May 31, 2007, but Tenant understands that Landlord is negotiating to try to relocate Eureka to alternate premises earlier than that date so that the space can be made available to Tenant earlier than otherwise. Landlord will use commercially-reasonable efforts to secure such an early termination but makes no representations nor warranties about its ability to do so on commercially-acceptable terms. Landlord will give Tenant prompt notice if and when it secures a fully-executed legal agreement with the Eureka to vacate Suite 580 prior to May 31, 2007, along with an estimate of the date on which Suite 580 will be available for Tenant’s occupancy. The date on which Landlord delivers Suite 580 to Tenant shall be referred to as the “Suite 580 Commencement Date”. As detailed in Section 2.3 of the Lease, Landlord shall not be liable for any delay in being able to deliver the space for any reason including but not limited to Eureka’s unauthorized holdover in the space.

Failure of Landlord to be able to deliver any of the three subject suites shall not impact Tenant’s obligation to the lease the others pursuant to the terms hereof nor shall it impact Landlord’s agreed efforts to secure the spaces for Tenant.

III.	LEASE TERM:

Tenant shall lease Suites 395, 575 and 580 from their respective Commencement Dates through December 31, 2011 (the “Suite 395, 575 and 580 Expiry Date”).

IV.	RENT AND EXPENSES:

Beginning on the respective Commencements Dates for each suite, Tenant shall pay Base Monthly Rent as follows:

Suite 395: $700.00 per month, increasing on January 1, 2007 and annually thereafter by three percent (3%).

Suite 575: $6,811.44 per month, increasing on January 1, 2007 and annually thereafter by three percent (3%). Suite 575 Base Rent shall be reduced by fifteen percent (15%) during the period between the Suite 575 Commencement Date and the Suite 580 Commencement Date, regardless of when that latter date occurs, if ever. Upon the Suite 580 Commencement Date the discount of Base Rent for Suite 575 shall cease and it shall be restored to its full, stated amount.

Suite 580: $2,899.71 per month, increasing on January 1, 2007 and annually thereafter at three percent (3%).

In the event any of the respective Commencement Dates occurs on other than the first day of a calendar month, the Base Monthly Rents shall be pro-rated accordingly.

The Base Monthly Rent for Suite 395 is meant to be fully inclusive of all Operating Expenses and Taxes, such that no additional payments in respect of those costs shall be due from Tenant.

The Base Monthly Rent amounts shown above for Suites 575 and 580 are intended to be fully triple-net of all Operating Expenses and Taxes. As such, there is no Base Year applicable to

either Suite 575 nor to 580 as there is with Tenant’s premises existing in advance of this Fourth Amendment. In addition to Base Monthly Rent for Suite 575 and 580, Tenant is also obligated to pay Rent Adjustments and Rent Adjustment Deposits beginning on the respective suites’ Commencement Dates per the terms of the Lease, with the exception that all references to the “Base Year” that appear in the definitions of Rent Adjustment Deposits, Operating Expenses, Taxes and in Lease Sections 1.1(13) and 4.1 do not apply.

V.	PREMISES CONDITION / TENANT IMPROVEMENTS:
