(c)                                  All Common Areas shall be subject to the exclusive control and management of Landlord and Landlord shall have the right to establish, modify, amend and enforce reasonable rules and regulations with respect to the Common Areas.  Tenant acknowledges receipt of a copy of the current rules and regulations (the “Rules”) attached hereto as EXHIBIT “C”, and agrees that they may, from time to time, be modified or amended by Landlord in a commercially reasonable manner.  Tenant agrees to abide by and conform with the Rules; to cause its concessionaires and its and their employees and agents to abide by the Rules; and to use its best efforts to cause its customers, invitees and licensees to abide by the Rules.  Notwithstanding the foregoing, Landlord shall not establish, amend or modify any rule or regulation which will materially and adversely impact Tenant’s use, occupancy and access to the Premises and Common Areas without the prior written consent of Tenant, which consent shall not be unreasonably withheld.

2.                                       USE:

Tenant may use the Premises solely for office, administrative and research and development uses (“Tenant’s Intended Use”) and for no other use without Landlord’s prior written consent.  Tenant shall, at Tenant’s expense, comply promptly with all applicable federal, state and local laws, regulations, ordinances, rules, orders, and requirements in effect during the Term relating to the condition, use or occupancy of the Premises.  Tenant shall not use or permit the use of the Premises in any manner that will tend to create waste or a nuisance, or that unreasonably disturbs other tenants of the Building or Park, nor shall Tenant place or maintain any signs, antennas, awnings, lighting or plumbing fixtures, loudspeakers, exterior decoration or similar devises on the Building or the Park or visible from the exterior of the Premises without Landlord’s prior written consent, which consent may be withheld in Landlord’s sole discretion.

3.                                       TERM; POSSESSION:

(a)                                  The initial term of this Lease (the “Initial Term”) is for a period of three (3) Lease Years commencing on the date (the “Commencement Date”) the Premises are delivered to Tenant in “substantially completed” condition (as defined in Paragraph 23), subject to adjustment for Tenant Delays (defined below), and shall continue until midnight on the last day of the third Lease Year (the “Expiration Date”), unless extended or sooner terminated as hereinafter provided.  The Initial Term, together with each and every “Extended Term” (as defined in Paragraph 22 hereof) which shall be duly exercised by Tenant pursuant to the provisions of Paragraph 22, are hereinafter collectively called the “Term”.  The estimated

2

Commencement Date is August 1, 2004 (the “Estimated Commencement Date”).  Landlord shall deliver possession of the Premises to Tenant free and clear of all tenancies and occupancies, broom clean and in good order and condition and with all alterations and improvements, if any, to be made by Landlord as may be elsewhere provided for in this Lease, substantially completed in a first-class workmanlike manner.  If for any reason Landlord has not delivered to Tenant possession of the Premises by the Estimated Commencement Date, this Lease shall remain in effect and Landlord shall not be liable to Tenant for any loss or damage resulting therefrom, except as otherwise provided herein.

(b)                                 For purposes of this Lease, the first “Lease Year” shall mean the period commencing on the Commencement Date and ending twelve (12) months thereafter, except that if the Commencement Date is other than the first day of a calendar month, the first “Lease Year” shall mean the period commencing on the Commencement Date and ending on the last day of the twelfth (12th) full calendar month after the Commencement Date.  Thereafter, the term “Lease Year” shall mean a period equal to twelve (12) full calendar months, except that if the Commencement Date is other than the first day of a calendar month the final “Lease Year” shall be extended as necessary to ensure that the Lease expires at the end of the Term.

(c)                                  If the Commencement Date of the Lease has not occurred on or before the Estimated Commencement Date, and if the cause of the delay in the occurrence of the Commencement Date is solely attributable to Tenant, then the Lease shall begin on the date the Commencement Date otherwise would have occurred but for the Tenant delays (“Tenant Delays”).  Tenant Delays shall include, without limitation, those caused by (a) any changes to the Work (defined in Paragraph 23) requested by Tenant, and (b) Tenant’s or Tenant’s agents’ interference with Landlord’s performance of the Work.  All costs and expenses occasioned by a Tenant Delay, including, without limitation, increases in labor or materials, shall be borne by Tenant.

(d)                                 Following the date on which Landlord delivers possession of the Premises to Tenant and the Commencement Date, Landlord may prepare and deliver to Tenant a commencement date memorandum (the “Commencement Date Memorandum”) in the form of EXHIBIT “D”, attached hereto, subject to such changes in the form as may be required to insure the accuracy thereof.  The Commencement Date Memorandum shall certify the date on which Landlord delivered possession of the Premises to Tenant and the dates upon which the Term commences and expires.

4.                                       RENT:

(a)                                  Tenant shall pay to Landlord the monthly rental (herein called “Base Rent”) for the Premises in the amounts specified in the Addendum, attached hereto and made a part hereof.  Tenant shall pay to Landlord the Base Rent, in advance, on the 1^st day of each and every calendar month during the Term of this Lease, without notice or demand and without any set-off or deduction, except to the extent otherwise expressly provided for in this Lease.  If the Term commences on other than the first day of a calendar month, the first payment of Base Rent shall be appropriately prorated on the basis of the number of days in such calendar month.  All Rent due or to become due hereunder shall be paid to Landlord at its address set forth in this Lease, unless Landlord shall designate some other payee or address for the payment thereof by

3

giving written notice to that effect to Tenant.  For purposes of this Lease, the term “Rent” shall mean the Base Rent, all additional rent and all of the other monetary obligations of Tenant under this Lease.

(b)                                 Tenant shall pay, as additional rent, all amounts of money required to be paid to Landlord by Tenant under this Lease in addition to monthly Base Rent whether or not the same is designated “additional rent.” Tenant shall pay to Landlord all additional rent upon Landlord’s written request or otherwise as provided in this Lease.

(c)                                  Tenant acknowledges that late payment of Rent to Landlord will cause Landlord to incur costs not contemplated by this Lease, the exact amount of which is extremely difficult to ascertain.  Such costs include, but are not limited to, processing and accounting charges, and late charges which may be imposed on Landlord by the terms of any trust deed covering the Premises.  Accordingly, if any installment of Rent or any other sums due from Tenant shall not be received by Landlord within ten (10) days after the date such payment is due, Tenant shall pay to Landlord a late charge in an amount equal to two percent (2%) of such overdue amount.  The parties agree that such late charge represents a fair and reasonable estimate of the costs Landlord will incur by reason of late payment by Tenant.  Acceptance of such late charge by Landlord shall not constitute a waiver of Tenant’s default with respect to such overdue amount, nor prevent Landlord from exercising any of the other rights and remedies granted hereunder.

5.                                       UTILITIES AND SERVICES:

(a)                                  Landlord shall furnish the following utilities and services in and to the Premises, to wit:  (i) heat and air-conditioning (“HVAC”) as may be required to maintain the Premises at reasonably comfortable temperatures during business hours as hereinafter defined; (ii) hot and cold water; (iii) adequate elevator service as may be reasonably required; (iv) janitorial service; (v) electricity in amounts reasonably required for Tenant’s Intended Use; and (vi) adequate sewer systems (storm and sanitary).  Business hours shall be between the hours of 7:00 A.M. and 6:00 P.M. Monday through Friday, excluding State and National holidays.  Upon request of Tenant, Landlord shall furnish such utilities and services in excess of the above requirements and/or outside of business hours, but only to the extent that same are available and only if Tenant agrees to pay the additional cost thereof.  The current after business hours HVAC charge is Twenty-Five Dollars ($25.00) per hour.

(b)                                 To the extent that any utility is separately furnished and metered to the Premises as of the Commencement Date, Tenant shall be solely responsible for and promptly pay all charges for such separately metered utility as they are billed to Tenant by the utility company supplying same.  Tenant shall not be required to install or pay the cost of installation of a separate meter.

(b)                                 Tenant shall, at Tenant’s expense, maintain every part of the Premises in good order, condition and repair, including without limitation, (i) all interior surfaces, ceilings, non-load bearing walls, door frames, window frames, floors, carpets, draperies, window coverings and fixtures, (ii) all windows, doors, locks and closing devices, entrances and signs, (iii) all plumbing and sewage pipes (except to the extent otherwise provided for hereinabove), fixtures and fittings in the Premises, (iv) all phone lines, electrical wiring, equipment, switches, outlets and light bulbs in the Premises, (v) all of Tenant’s personal property, improvements and alterations, and (vi) all other fixtures and special items installed by or for the benefit of, or at the expense of Tenant.  Tenant shall not enter onto the roof area of the Building.  Tenant shall not commit any waste on or to the Premises and shall keep the Premises in a clean, neat and orderly condition except to the extent Landlord is required to do so pursuant to subparagraph (a) above or subparagraph 5(a).

in accordance with all applicable laws.  Tenant may remove any or all interior and non-structural Alterations and any signage (whether or not interior or non-structural) from the Premises at any time prior to the expiration of the Term, provided that any damage caused by such removal shall be repaired by Tenant.  Landlord, by written notice at the time consent for such Alteration is given, may require that Tenant, at Tenant’s expense, remove any Alterations prior to or upon the expiration of this Lease, and restore the Premises to their condition prior to such Alterations.  Unless Landlord requires their removal, as provided above, all Alterations made to the Premises shall become the property of Landlord and remain upon and be surrendered with the Premises upon the expiration of this Lease.

(i)                                     “Tenant’s Building Percentage Share” shall mean the percentage equal to the rentable square footage of the Premises divided by the rentable square footage of the Building (i.e., 11,000 rsf / 40,000 rsf = 25.5%),

(ii)                                  “Tenant’s Park Percentage Share” shall mean the percentage equal to the rentable square footage of the Premises divided by the rentable square footage of the Park (i.e., 11,000 rsf / 91,000 rsf = 12.09%),

(d)                                 Estimates of Operating Expenses.  Tenant shall pay to Landlord each month at the same time and in the same manner as monthly Base Rent one-twelfth (1/12th) of Landlord’s estimate of the amount of Operating Expenses payable by Tenant for the then-current calendar year.  If at any time it appears to Landlord that Tenant’s share of Operating Expenses payable for the current calendar year will vary from Landlord’s estimate, Landlord may give notice to Tenant of Landlord’s revised estimate for the calendar year, and subsequent payments by Tenant for the calendar year shall be based on the revised estimate.  Within one hundred twenty (120) days after the close of each calendar year, or as soon after such 120-day period as practicable, Landlord shall deliver to Tenant a statement in reasonable detail of the actual amount of Operating Expenses payable by Tenant for such calendar year.  Landlord’s failure to provide such statement to Tenant within the 120-day period shall not act as a waiver and shall not excuse Tenant or Landlord from making the adjustments to reflect actual costs as provided herein.  If on the basis of such statement Tenant owes an amount that is less than the estimated payments for such calendar year previously made by Tenant, Landlord shall credit such excess against the next payment of Operating Expenses due.  If on the basis of such statement Tenant owes an amount that is more than the estimated payments for such calendar year previously made by Tenant, Tenant shall pay the deficiency to Landlord within fifteen (15) business days after delivery of the statement.  In addition, if, after the end of any calendar year or

7

any annual adjustment of Operating Expenses for a calendar year, Operating Expenses are incurred or billed to Landlord that are attributable to any period within the Term (e.g., sewer district flow fees), Landlord shall notify Tenant of its share of such additional Operating Expenses and Tenant shall pay such amount to Landlord within ten (15) business days after Landlord’s written request therefor.  The obligations of Landlord and Tenant under this Paragraph with respect to the reconciliation between the estimated and actual amounts of Operating Expenses payable by Tenant for the last year of the Term shall survive the termination of this Lease.  Landlord shall keep and maintain complete and accurate books and records reflecting such Operating Expenses and Taxes for a period of at least two (2) years following the period in which Operating Expenses and Taxes were incurred.  Tenant or its representatives shall have one hundred twenty (120) days from after Tenant receives the year-end statement of the adjustment to the Operating Expenses for the prior calendar year to notify Landlord in writing of Tenant’s desire to conduct, at Tenant’s sole cost and expense, an audit of Landlord’s books and records relating to the prior calendar year.  Any such audit must be conducted by Tenant or its agent during regular business hours at the offices of Landlord or the offices of Landlord’s designated agent and must be completed within one hundred fifty (150) days after Tenant receives the applicable year-end statement.  The person or entity performing the audit or review of Landlord’s books and records on Tenant’s behalf or at Tenant’s request may not be compensated for the audit or review on a contingency fee basis.  Any payment of Additional Rent by Tenant shall be made without prejudice to any right of Tenant to dispute any item theretofore billed pursuant to the provisions of this subparagraph (d).

8.2.                              Taxes.

(a)                                  Tenant shall pay to Landlord, as additional rent, Tenant’s Park Percentage Share of any increase in Taxes for the Park over Base Taxes during each year of the Term (prorated for any partial calendar year during the Term).  The term “Base Taxes” shall mean those taxes incurred by Landlord during the Base Year.

(b)                                 Definition of Taxes.  The term “Taxes” shall include all transit charges, housing fund assessments, real estate taxes and all other taxes relating to the Premises, Building and Park of every kind and nature whatsoever, including any supplemental real estate taxes attributable to any period during the Term; all taxes which may be levied in lieu of real estate taxes; and all assessments, assessment bonds, levies, fees, penalties (if a result of Tenant’s delinquency) and other governmental charges (including, but not limited to, charges for parking, traffic and any storm drainage/flood control facilities, studies and improvements, water and sewer service studies and improvements, and fire services studies and improvements); and all amounts necessary to be expended because of governmental orders, whether general or special, ordinary or extraordinary, unforeseen as well as foreseen, of any kind and nature for public improvements, services, benefits or any other purpose, which are assessed, based upon the use or occupancy of the Premises, Building and/or Park, or levied, confirmed, imposed or become a lien upon the Premises, Building and/or Park, or become payable during the Term, and which are attributable to any period within the Term and not solely attributable to the use of any other tenant in the Building or Park.

(c)                                  Limitation.  Nothing contained in this Lease shall require Tenant to pay (i) any franchise, estate, inheritance, succession or transfer tax of Landlord, (ii) for any

8

increase in taxes resulting from a change of ownership of the Land or the Building, or (iii) any income, profits or revenue tax or charge upon the net income of Landlord from all sources; provided, however, that if at any time during the Term in under the laws of the United States Government or the State of California, or any political subdivision thereof, a tax or excise on rent, or any other tax however described, is levied or assessed by any such political body against Landlord on account of Rent, or any portion thereof, Tenant shall pay one hundred percent (100%) of any said tax or excise as additional rent.

(d)                                 Installment Election.  In the case of any Taxes which may be evidenced by improvement or other bonds or which may be paid in annual or other periodic installments, Landlord shall elect to cause such bonds to be issued or such assessment to be paid in installments over the maximum period permitted by law.

(e)                                  Estimate of Tenant’s Share of Taxes.  Prior to the commencement of each calendar year during the Term, or as soon thereafter as reasonably practicable, Landlord shall notify Tenant in writing of Landlord’s estimate of the amount of Taxes which will be payable by Tenant for the ensuing calendar year.  On or before the first day of each month during the ensuing calendar year, Tenant shall pay to Landlord in advance, together with Base Rent, one-twelfth (1/12th) of the estimated amount; provided, however, if Landlord fails to notify Tenant of the estimated amount of Tenant’s share of Taxes for the ensuing calendar year prior to the end of the current calendar year, Tenant shall be required to continue to pay to Landlord each month in advance Tenant’s estimated share of Taxes on the basis of the amount due for the immediately prior month until twenty (20) days after Landlord notifies Tenant of the estimated amount of Tenant’s share of Taxes for the ensuing calendar year.  If at any time it appears to Landlord that Tenant’s share of Taxes payable for the current calendar year will vary from Landlord’s estimate, Landlord may give notice to Tenant of Landlord’s revised estimate for the year, and subsequent payments by Tenant for the year shall be based on the revised estimate.

(f)                                    Annual Adjustment.  Within one hundred twenty (120) days after the close of each calendar year during the Term, or as soon after the one hundred twenty (120) day period as reasonably practicable, Landlord shall deliver to Tenant a statement of the adjustment to the Taxes for the prior calendar year.  If, on the basis of the statement, Tenant owes an amount that is less than the estimated payments for the prior calendar year previously made by Tenant, Landlord shall apply the excess to the next payment of Taxes due.  If, on the basis of the statement, Tenant owes an amount that is more than the amount of the estimated payments made by Tenant for the prior calendar year, Tenant shall pay the deficiency to Landlord within thirty (30) days after delivery of the statement.  The year end statement shall be binding upon Tenant unless Tenant notifies Landlord in writing of any objection thereto within thirty (30) days after Tenant’s receipt of the year end statement.  In addition, if, after the end of any calendar year or any annual adjustment of Taxes for a calendar year, any Taxes are assessed or levied against the Premises, Building or Building that are attributable to any period within the Term (e.g., supplemental taxes or escaped taxes), Landlord shall notify Tenant of its share of such additional Taxes and Tenant shall pay such amount to Landlord within twenty (20) days after Landlord’s written request therefor.

9.5.                              Indemnity.  Except if and to the extent that such party is released from liability to the other party hereto pursuant to the provisions of Paragraph 9.4 above,

(a)                                  Landlord does hereby assume liability for, and does hereby agree to indemnify, protect, defend, save and hold harmless Tenant and its officers, directors, agents and employees, from and against any and all liabilities, obligations, claims, actions, demands, fines, suits, judgments, penalties, damages and losses (including all of the costs, fees and expenses connected therewith or incident thereto) for death of or injury to any person whomsoever and for loss of, damage to, or destruction of any property whatsoever (including loss of use thereof) arising out of the negligence or willful misconduct of Landlord and its officers, partners, employees, agents, representatives or contractors (collectively, “Landlord’s Parties”) as they relate to the Park, Land, Building and/or the Premises; and

(b)                                 Tenant does hereby assume liability for, and does hereby agree to indemnify, protect, defend, save and hold harmless Landlord, its officers, directors, agents and employees, from and against any and all liabilities, obligations, claims, actions, demands, fines, suits, judgements, penalties, damages and losses (including all of the costs, fees and expenses connected therewith or incident thereto) for death of or injury to any person whomsoever and for loss of, damage to, or destruction of any property whatsoever (including loss of use thereof) arising out of (i) any condition or occurrence in or resulting from any condition or occurrence in

11

the Premises during the Term, except to the extent caused by the negligence or willful misconduct of Landlord or Landlord’s Parties, or (ii) any act or omission of Tenant or Tenant’s agents, representatives, officers, directors, shareholders, partners, employees, successors and assigns, wherever it occurs.

(c)                                  The provisions of this Paragraph shall survive the termination or expiration of this Lease with respect to any damage, injury, or death occurring prior to such expiration or termination.

10.                                 ASSIGNMENT AND SUBLETTING:

(a)                                  Assignment and Subletting.  Tenant shall not assign this Lease or sublet all or any portion of the Premises without the prior written consent of Landlord, which consent shall not be unreasonably withheld or delayed.  Notwithstanding the foregoing, however, Tenant may assign this Lease or sublet all or any portion of the Premises without Landlord’s prior written consent to any corporation which is directly or indirectly controlled by or under common control with Tenant or to any entity which shall acquire a business segment of Tenant which conducts operations at the Premises.  No assignment or subletting shall release Tenant from any of its obligations or liabilities under this Lease.  Any purported assignment or subletting contrary to the provisions of this Lease without Landlord’s prior written consent shall be void.  The consent by Landlord to any assignment or subletting shall not constitute a waiver of the necessity for obtaining Landlord’s consent to any subsequent assignment or subletting.  Landlord may consent to any subsequent assignment or subletting, or any amendment to or modification of this Lease with the 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 any liability under this Lease.

(b)                                 Information to be Furnished.  If Tenant desires at any time to assign its interest in this Lease or sublet the Premises, Tenant shall first notify Landlord of its desire to do so and shall submit in writing to Landlord:  (i) the name of the proposed assignee or subtenant; (ii) the nature of the proposed assignee’s or subtenant’s business to be conducted in the Premises; (iii) the terms and provisions of the proposed assignment or sublease, including the date upon which the assignment shall be effective or the commencement date of the sublease and a copy of the proposed form of assignment or sublease; and (iv) such financial information, including financial statements, and other information as Landlord may reasonably request concerning the proposed assignee or subtenant.

(c)                                  Bonus Rental.  If, in connection with any assignment or sublease, Tenant receives rent or other consideration, either initially or over the term of the assignment or sublease, in excess of the Rent called for hereunder, or in case of the sublease of a portion of the Premises, in excess of such Rent fairly allocable to such portion, Tenant shall pay to Landlord, as additional rent hereunder, fifty percent (50%) of the excess of each such payment of Rent or other consideration received by Tenant after deducting all of the costs of subletting or assigning the space including, but not limited to broker’s commissions, rent concessions, improvement allowances, attorneys fees and costs, promptly after Tenant’s receipt of such Rent or other consideration.

12

(d)                                 Transfer of a Majority Interest.  If Tenant is a non-publicly traded corporation, the transfer (as a consequence of a single transaction or any number of separate transactions) of fifty percent (50%) or more or of a controlling interest or the beneficial ownership interest of the voting stock of Tenant issued and outstanding as of the date of this Lease shall constitute an assignment hereunder for which Landlord’s prior written consent is required.  If Tenant is a partnership, limited liability company, trust or an unincorporated association, the transfer of a controlling or majority interest therein shall constitute

11.                                 PARKING:

Landlord grants to Tenant and Tenant’s customers, suppliers, employees and invitees during the Term the right to use in the parking areas designated on EXHIBIT “E” thirty-seven (37) parking spaces on a non-exclusive basis for the use of motor vehicles, subject to rights reserved to Landlord as specified herein.  Landlord reserves the right to grant similar nonexclusive rights to other tenants; to promulgate rules and regulations relating to the use of the including parking area; to make changes in the parking layout from time to time; and to do and perform any other acts in and to these areas and improvements as Landlord determines to be advisable.  Landlord shall have the unqualified right to rearrange or reduce the number of parking spaces; provided, however, the ratio of the number of parking spaces available to Tenant will be no less than 3.8 spaces per 1,000 usable square feet of the Premises.

12.                                 SUBORDINATION:

Tenant agrees upon request of Landlord to subordinate this Lease and its rights hereunder to the lien of any mortgage, deed of trust or other voluntary hypothecation arising out of any security instrument duly executed by Landlord charged against the Land, Building and Premises, or any portion or portions thereof, and to execute at any time and from time-to-time such documents as may be reasonably required to effectuate such subordination; provided, however, that Tenant shall not be required to effectuate any such subordination or other document hypothecating any interest in the Land, Building or Premises unless the mortgagee or beneficiary named in such mortgage or deed of trust (the “Holder”) shall first enter into Holder’s commercially reasonable standard form of Subordination, Non-Disturbance and Attornment Agreement which provides that Holder shall not disturb Tenant’s quiet enjoyment of the Premises or terminate or cancel any of Tenant’s rights or interests under this Lease so long as Tenant is not in default under this Lease.  Tenant shall execute such documents within twenty (20) days after Landlord’s written request.

13.                                 DAMAGE OR DESTRUCTION:

(a)                                  Landlord’s Obligation to Rebuild.  Subject to the provisions of Paragraphs (b), (c) and (d) below, if, during the Term, the Premises are totally or partially destroyed, Landlord shall, within forty-five (45) days after the destruction, commence to restore the Premises to substantially the same condition as they were in immediately before the destruction and prosecute the same diligently to completion.  Such destruction shall not terminate this Lease.  Landlord’s obligation shall not include repair or replacement of Tenant’s alterations or Tenant’s equipment, furnishings, fixtures and personal property.  If the existing laws do not permit the Premises to be restored to substantially the same condition as they were in immediately before

13

destruction, and Landlord is unable to get a variance to such laws to permit the commencement of restoration of the Premises within the 45-day period, then either party may terminate this Lease by giving written notice to the other party within thirty (30) days after expiration of the 45-day period.

(b)                                 Right to Terminate.

(i)                                     Landlord’s Right to Terminate.  Landlord shall have the option to terminate this Lease if the Premises or the Building is destroyed or damaged by fire or other casualty, regardless of whether the casualty is insured against under this Lease, if Landlord reasonably determines that (i) there are insufficient insurance proceeds made available to Landlord to pay all of the costs of the repair or restoration or (ii) the repair or restoration of the Premises or the Building cannot be substantially completed within one hundred fifty (150) days after the date of the casualty.  If Landlord elects to exercise the right to terminate this Lease as a result of a casualty, Landlord shall exercise the right by giving Tenant written notice of its election to terminate this Lease within forty-five (45) days after the date of the casualty, in which event this Lease shall terminate effective as of the date of the casualty.

(ii)                                  Tenant’s Right to Terminate.  Tenant shall have the option to terminate this Lease if the Premises or the Building is destroyed or damaged by fire or other casualty, regardless of whether the casualty is insured against under this Lease, if Landlord reasonably determines that the repair or restoration of the Premises or the Building cannot be substantially completed within one hundred fifty (150) days after the date of the casualty.  If Tenant elects to exercise the right to terminate this Lease as a result of a casualty, Tenant shall exercise the right by giving Landlord written notice of its election to terminate this Lease within thirty (30) days after Landlord notifies Tenant in writing of its estimate of the time required to substantially repair or restore the Premises or the Building, in which event this Lease shall terminate effective as of the date of the casualty.

(iii)                               Commencement of Repair.  If neither party exercises its right to terminate this Lease pursuant to this Section 13.b, Landlord shall promptly commence the process of obtaining all of the necessary permits and approvals for the repair or restoration of the Premises or the Building as soon as practicable and thereafter prosecute the repair or restoration of the Premises or the Building diligently to completion and this Lease shall continue in full force and effect.

(c)                                  Last Year of Term.  Landlord shall have the right to terminate this Lease upon thirty (30) days’ prior written notice to Tenant if the Premises or Building is substantially destroyed or damaged during the last twelve (12) months of the Term.  Landlord shall notify Tenant in writing of its election to terminate this Lease under this Paragraph (c), if at all, within forty-five (45) days after Landlord determines that the Premises or Building has been substantially destroyed.  If Landlord does not elect to terminate this Lease, the repair of the Premises or Building shall be governed by Paragraphs (a), (b) and (d).

(d)                                 Uninsured Casualty.  If the Premises are damaged from any uninsured casualty to any extent whatsoever, Landlord may within forty-five (45) days following the date of such damage:  (i) commence to restore the Premises to substantially the same condition as

14

they were in immediately before the destruction and prosecute the same diligently to completion, in which event this Lease shall continue in full force and effect; or (ii) within the 45-day period Landlord may elect not to so restore the Premises, in which event this Lease shall cease and terminate.  In either such event, Landlord shall give Tenant written notice of its intention within the 45-day period.

(e)                                  Abatement of Rent.  In the event of destruction or damage to the Premises which materially interferes with Tenant’s use of the Premises, if this Lease is not terminated as above provided, there shall be an abatement or reduction of Base Rent between the date of destruction and the date Landlord substantially completes its reconstruction obligations, based upon the extent to which the destruction materially interferes with Tenant’s use of the Premises.  All other obligations of Tenant under this Lease shall remain in full force and effect.  Except for abatement of Base Rent, Tenant shall have no claim against Landlord for any loss suffered by Tenant due to damage or destruction of the Premises or any work of repair undertaken as herein provided.

(f)                                    Waiver.  The provisions of California Civil Code Sections 1932(2) and 1933(4), and any successor statutes, are inapplicable with respect to any destruction of the Premises, such sections providing that a lease terminates upon the destruction of the Premises unless otherwise agreed between the parties to the contrary.

14.                                 CONDEMNATION:

If the Building or any part thereof shall be taken for any public or quasi-public use in condemnation proceedings or by any right of eminent domain or sale in lieu of condemnation, this Lease shall terminate as of the date of taking and any prepaid Rent and other charges shall be refunded to Tenant; provided, however, that if less than the entire Building shall be so taken and, in Tenant’s reasonable opinion, the Premises (or the portion remaining) are adequate and suitable for Tenant’s Intended Use, then this Lease shall continue in full force and effect as to that portion of the Premises remaining and the monthly installment of Rent payable hereunder after the date of said taking and for the remainder of the Term hereof shall be reduced in the same proportion as the floor area of the Premises is reduced by said taking.  In such an event (i.e. the continuance of this Lease as to the portion remaining), Landlord shall make every reasonable effort to diligently restore said Building and Premises as closely as reasonably possible to their condition immediately prior to the taking, however it is agreed that Landlord shall not be required to expend more than the amount of the condemnation proceeds.  Landlord shall at all times keep Tenant fully advised of any condemnation proceedings or threat thereof.  Any award or compensation arising out of such taking shall belong to and be paid to Landlord except with respect to any separate award made to Tenant for its leasehold improvements and fixtures, relocation expenses and other damages or costs pursuant to a separate independent action taken by Tenant against the condemning authority.  In the event that any access to the Premises or any parking spaces as may be granted to Tenant herein are so taken, Landlord shall promptly substitute similarly situated access or parking spaces of equal quality therefor, failure of Landlord so to do giving Tenant the right to terminate this Lease as of the date of taking by giving written notice thereof to Landlord.

15

15.                                 ACCESS:

Landlord’s agents, employees, contractors, prospective purchasers, existing and prospective mortgagees, and, during the last nine (9) months of the Term, prospective tenants, shall have the right to enter the Premises at reasonable times with prior reasonable notice to Tenant for the purpose of inspecting the same; and further, Landlord and its employees, agents and contractors shall have the right to enter the Premises without notice at any time as may be necessary for the purpose of making repairs thereto and to the Building and its mechanical systems and for the purpose of performing the services to be performed by Landlord pursuant to the terms of this Lease; provided in every instance, however, that any such party so entering upon the Premises shall cause as little inconvenience, annoyance and disturbance to Tenant as may be reasonably possible under the circumstances and shall comply with all reasonable security regulations and procedures as may then be in effect with respect to Tenant’s operations in the Premises.

16.                                 DEFAULT BY TENANT; REMEDIES:

16.1.                        Default.  The occurrence of any of the following events shall constitute an event of default on the part of Tenant under this Lease:

(a)                                  Tenant defaults in the payment of any installment of Rent or any other sum specifically to be paid by Tenant hereunder and such default shall not have been cured within ten (10) business days after Landlord shall have given to Tenant written notice specifying such default;

(b)                                 Tenant defaults in the observance or performance of any of Tenant’s other covenants hereunder (other than the covenant to pay Rent or any other sum herein specified to be paid by Tenant) and such default shall not have been cured within thirty (30) days after Landlord shall have given to Tenant written notice specifying such default; provided, however, that if the default complained of shall be of such a nature that the same cannot be completely remedied or cured within such thirty-day period, then such default shall not be an enforceable default against Tenant for the purposes of this Paragraph if Tenant shall have commenced curing such default within such thirty-day period and shall proceed with reasonable diligence and in good faith to remedy the default complained of;

(c)                                  Tenant, finally and without further possibility of appeal or review, (i) is adjudicated bankrupt or insolvent, or (ii) has a receiver or trustee appointed for all or substantially all of its business or assets on the ground of Tenant’s insolvency, or (iii) suffers an order to be entered approving a petition filed against Tenant seeking reorganization of Tenant under the Federal Bankruptcy Laws or any other applicable law or statute of the United States or any State thereof; and

(d)                                 Tenant makes an assignment for the benefit of its creditors, or files a voluntary petition in bankruptcy or a petition or answer seeking reorganization or arrangement under the Federal Bankruptcy Laws or any other applicable law or statute of the United States or any State thereof, or files a petition to take advantage of any insolvency act or shall consent to the appointment of a receiver or trustee of all or a substantial part of its business and property.

16

16.2.                        Remedies.  In the event of any default or breach by Tenant and a failure to cure same within the applicable cure period, if any, Landlord may at any time thereafter, without limiting Landlord in the exercise of any right or remedy at law or in equity which Landlord may have by reason of such default or breach:

(a)                                  Continue Lease.  Pursue the remedy described in California Civil Code Section 1951.4 whereby Landlord may continue this Lease in full force and effect after Tenant’s breach and recover the Rent and any other monetary charges as they become due, without terminating Tenant’s right to sublet or assign this Lease, subject only to reasonable limitations as herein provided.  During the period Tenant is in default, Landlord shall have the right to do all acts necessary to preserve and maintain the Premises as Landlord deems reasonable and necessary, including removal of all persons and property from the Premises, and Landlord can enter the Premises and relet them, or any part of them, to third parties for Tenant’s account.  Tenant shall be liable immediately to Landlord for all costs Landlord incurs in reletting the Premises, including, without limitation, brokers’ commissions, expenses of remodeling the Premises required by the reletting, and like costs.  Reletting can be for a period shorter or longer than the remaining Term.

(b)                                 Perform.  Pay or perform such obligation due (but shall no be obligated to do so), if Tenant fails to pay or perform any obligations when due under this Lease within the time permitted for their payment or performance.  In such case, the costs incurred by Landlord in connection with the performance of any such obligation will be additional rent due under this Lease and will become due and payable on demand by Landlord.

(c)                                  Terminate.  Terminate Tenant’s rights to possession by any lawful means, in which case this Lease shall terminate and Tenant shall immediately surrender possession of the Premises to Landlord.  In such event Landlord shall be entitled to recover from Tenant all damages incurred by Landlord by reason of Tenant’s default, including, without limitation, the following:  (A) the worth at the time of award of any unpaid Rent which had been earned at the time of such termination; plus (B) 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 is proved could have been reasonably avoided; plus (C) the worth at the time of award of the amount by which the unpaid Rent for the balance of the Term after the time of award exceeds the amount of such Rent loss that is proved could be reasonably avoided; plus (D) 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 events would be likely to result therefrom; plus (E) at Landlord’s election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by applicable State law.  In addition, Landlord shall be entitled to recover from Tenant the unamortized portion of any tenant improvement allowance, free rent or other allowance provided by Landlord to Tenant and any brokerage commission or finders fee paid or incurred by Landlord in connection with this Lease (amortized on straight line-basis over the original term of this Lease.) Upon any such termination of Tenant’s possessory interest in and to the Premises, Tenant (and at Landlord’s sole election, Tenant’s sublessees) shall no longer have any interest in the Premises, and Landlord shall have the right to make any reasonable repairs, alterations or modifications to the Premises which Landlord in its sole discretion deems reasonable and necessary.  The “worth at the time of award” of the amounts referred to in

17

subparagraphs (A) and (B) above is computed by allowing interest at a rate equal to eight percent (8%) per annum.  The worth at the time of award of the amount referred to in subparagraph (C) 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%).

(d)                                 Additional Remedies.  Pursue any other legal or equitable remedy available to Landlord.  Unpaid installments of Rent and other unpaid monetary obligations of Tenant under the terms of this Lease shall bear interest from the date due at the rate of five percent (5%) per annum.

(e)                                  Continue.  Even though Tenant has breached this Lease and abandoned the Premises, this Lease shall continue in effect for so long as Landlord does not terminate Tenant’s right to possession, and Landlord may enforce all its rights and remedies under this Lease, including the right to recover Rent as it becomes due under this Lease.  Acts of maintenance or preservation, efforts to relet the Premises, or the appointment of a receiver upon initiative of Landlord to protect Landlord’s interest under this Lease, shall not constitute a termination of Tenant’s right to possession.

17.                                 ESTOPPEL CERTIFICATES:

Tenant shall, within twenty (20) days after written request of Landlord, execute, acknowledge and deliver to Landlord or to Landlord’s mortgagee, proposed mortgagee, land lessor or proposed purchaser of the Building, any estoppel certificates requested by Landlord which shall state whether this Lease is in full force and effect and whether any changes may have been made to the original of this Lease; whether the Term of this Lease has commenced and full Rent is accruing; whether there are any defaults by Landlord and, if so, the nature of such defaults; whether possession has been assumed and all improvements to be provided by Landlord have been completed; whether Rent has been paid more than thirty (30) days in advance; whether there are any liens, charges, or offsets against Rent due or to become due; and whether the address shown on such estoppel certificate is accurate.  Landlord agrees that, within twenty (20) days after written request of Tenant, Landlord shall execute, acknowledge and deliver to Tenant a similar certificate.

18.                                 HOLDING OVER:

In the event Tenant remains in possession of the Premises after the expiration of the Term, it shall be deemed to be a tenant from month-to-month only, at one hundred fifty percent (150%) of the monthly installment of Rent in effect during the last month of the expired Term.  Except as aforesaid, such tenancy shall be upon and subject to the terms of this Lease.  Either party may terminate such tenancy by giving to the other at least thirty (30) days prior written notice of its intent to terminate.  Nothing herein, however, shall be deemed to grant to Tenant the right to hold over in the Premises beyond the expiration of the Term and Landlord shall be entitled to all remedies available to it, in law or in equity, as a result of any holding over in the Premises without Landlord’s consent.

18

19.                                 SURRENDER:

Tenant agrees to quit and surrender possession of the Premises to Landlord at the expiration of the Term in as good condition as when delivered by Landlord, except for the following:  (a) ordinary wear and tear, (b) Alterations not removed as permitted hereunder, (c) any appropriation or taking under power of eminent domain or by paramount authority, (d) damage by fire or other casualty, and (e) condition by reason of Landlord’s failure to repair as required of it hereunder.

20.                                 NOTICES:

All notices, requests, demands or other communications with respect to this Lease, whether or not herein expressly provided for, shall be in writing and shall be deemed to have been duly given either (a) forty-eight (48) hours after being mailed by United States First-Class, certified or registered mail, postage prepaid, return receipt requested, or (b) the next business day after being deposited (in time for delivery by such service on such business day) with Federal Express or another national courier service, for delivery to the parties at the following addresses (which such addresses may be changed by either party by giving written notice thereof to the other):

21.                                 QUIET ENJOYMENT:

Landlord covenants and agrees that Tenant, so long as it shall not be in default hereunder, shall and may, at all times during the Term, peaceably and quietly have, hold, occupy and enjoy the Premises and Common Areas pursuant to the terms of this Lease.

22.                                 RIGHT TO EXTEND:

(a)                                  Options to Extend.  Tenant shall have two (2) options to extend the Term for a period of two (2) years each (hereinafter referred to as the “First Extension Term” and “Second Extension Term,” respectively, and each, an “Extension Term”), provided that at the time Tenant’s Extension Notice (defined below) is given and at the time the Extension Term is to

19

commence no default by Tenant exists under this Lease.  Tenant shall exercise such option, if at all, by written notice (“Tenant’s Extension Notice”) to Landlord not later than eight (8) months, nor earlier than one (1) year, prior to the expiration of the original Term or the First Extension Term, as the case may be.  Tenant’s failure to deliver Tenant’s Extension Notice to Landlord in a timely manner shall be deemed a waiver of Tenant’s option to extend the Term and Tenant’s extension option, and any future option to extend the Term, shall lapse and be of no force or effect.

(b)                                 Exercise of Option.

(1)                                  First Extension Term.  If Tenant exercises its extension option for the First Extension Term, the Term shall be extended for an additional period of two (2) years on all of the terms and conditions of this Lease, except (i) Tenant’s options to further extend the Term shall be reduced in number by one, (ii) Landlord shall not be required to pay to Tenant any tenant improvement allowance or inducement and (iii) the monthly Base Rent for the First Extension Term shall be the greater of (A) an amount equal to ninety-five percent (95%) of the “Fair Market Rent” prevailing at the commencement of the First Extension Term or (B) the monthly Base Rent in effect at the end of the original Term.

(2)                                  Second Extension Term.  If Tenant exercises its extension option for the Second Extension Term, the Term shall be extended for an additional period of two (2) years on all of the terms and conditions of this Lease, except (i) Tenant shall have no further options to extend the Term, (ii) Landlord shall not be required to pay to Tenant any tenant improvement allowance or inducement and (iii) the monthly Base Rent for the Second Extension Term shall be the greater of (A) an amount equal to ninety-five percent (95%) of the “Fair Market Rent” prevailing at the commencement of the Second Extension Term or (B) the monthly Base Rent in effect at the end of the First Extension Term.

(c)                                  Determination of Fair Market Rent.  For the purposes of this Lease, the “Fair Market Rent” means the monthly base rent (i.e., rent other than operating expenses, taxes and insurance premiums) expected to prevail as of the commencement of an Extension Term for the entire Extension Term with respect to “full service” leases of comparable space within buildings located in Santa Rosa, California of a quality and with interior improvements, parking, site amenities, building systems, location, identity and access all comparable to that of the Premises, for a term equal to the Extension Term.  Landlord shall notify Tenant in writing (hereinafter referred to as “Landlord’s Notice”) within fifteen (15) days after receipt of Tenant’s Extension Notice of Landlord’s estimate of the Fair Market Rent for the Extension Term.  Within fifteen (15) days after receipt of Landlord’s Notice, Tenant shall either (i) notify Landlord in writing that Tenant accepts Landlord’s determination of Fair Market Rent for the Extended Term in or (ii) provide Landlord with its estimate of Fair Market Rent for the Extension Term.  If the parties are unable to reach an agreement on the Fair Market Rent within ten (10) days of exchanging such estimates than Tenant may rescind Tenant’s Extension Notice.  If the parties agree upon the Fair Market Rent number, the parties shall amend this Lease to provide for the Base Rent during the Extension Term.  If Tenant rescinds Tenant’s Extension Notice, Tenant shall be deemed to have waived its right to extend the Term.

20

(d)                                 Notice to Landlord and Tenant.  After the monthly Base Rent for an Extension Term has been set, Landlord and Tenant immediately shall execute an amendment to this Lease stating the monthly Base Rent.

23.                                 TENANT IMPROVEMENTS:

(a)                                  Landlord shall perform or cause to have performed on and to the Premises the work listed and/or shown on attached EXHIBIT “F”, all at Tenant’s sole cost and expense except to the extent provided below in Paragraph 23(e).  All such work (“Work”) shall be performed in a first-class workmanlike manner in strict accordance with the plans and specifications referenced in EXHIBIT “F” which have been approved by both Tenant and Landlord, and in accordance with all applicable governmental laws, rules, regulations and other requirements.  Landlord shall apply for and obtain all permits, licenses and certificates necessary for performance of the Work.  All of the said Work shall be “Substantially Completed” (as hereinafter defined) on or before the Commencement Date.  The Work shall be deemed to be “Substantially Completed” at such time as (i) Landlord shall certify in writing to Tenant that said Work has been completed in accordance with the foregoing provisions of this subparagraph (a), subject only to minor punch list items which shall be therein specifically noted and which shall be such as not to adversely affect Tenant’s use and occupancy of the Premises for Tenant’s Intended Use for a short duration of time, and (ii) a certificate of occupancy or “finaled” building permit is issued by the appropriate governmental authority with respect to the Premises and the Work.  Following substantial completion of the Work, Landlord shall obtain a certificate of occupancy for the Premises; provided, however, Landlord shall not be in default of this Section to the extent that Landlord is precluded or prevented from obtaining a certificate of occupancy for the Work or the Premises as a result of any actions or omissions by Tenant.

(b)                                 The minor punch list items referred to in subparagraph (a) immediately preceding shall not act to suspend or delay the Commencement Date, but Landlord shall, as soon as reasonably possible following the Commencement Date, complete said minor punch list items, together with such other defects as Tenant shall thereafter discover and which Tenant shall report to Landlord in writing within thirty (30) days following said Commencement Date.

(c)                                  Tenant shall have the right to enter upon the Premises at any time or times prior to the Commencement Date for the purpose of installing its equipment, fixtures, furniture and telecommunication systems, provided that in so doing the progress of the Work shall not be unreasonably interfered with or delayed.  Any such prior use of the Premises shall not constitute acceptance of the Premises nor shall it in any way be deemed a waiver of any rights Tenant might have under this Lease.

(d)                                 If for any reason whatever the Work is not Substantially Completed on or before the sixtieth (60th) day after the Estimated Commencement Date specified in Paragraph 3 hereof, then at any time thereafter, but prior to Substantial Completion, Tenant may terminate this Lease by written notice to Landlord and receive back all monies paid hereunder, in which event this Lease shall be null and void and neither party shall have any further obligation or liability hereunder; provided, however, that if Landlord would have Substantially Completed the Work on or before the Commencement Date specified in Paragraph 3 hereof but for (i) delays caused by strikes, fire, unusually severe and adverse weather conditions, unanticipated shortages
