Landlord and Tenant hereby agree as follows: 1. PREMISES. Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, upon the terms and subject to the conditions of this Lease, and subject to covenants, conditions and restrictions recorded in the real estate records in the county in which the Property is located, the space identified in the Basic Lease Information as the Premises (the "PREMISES"), in the Building located at the address specified in the Basic Lease Information (the "BUILDING"). The approximate configuration and location of the Premises is shown on Exhibit A. Landlord and Tenant agree that the rentable area of the Premises for all purposes under this Lease shall be the Rentable Area specified in the Basic Lease Information. The Building, together with the parking facilities serving the Building (the "PARKING FACILITY"), and the parcel(s) of land on which the Building and the Parking Facility are situated (collectively, the "PROPERTY"), is part of the Project identified in the Basic Lease Information (the "PROJECT"), which is part of the Development identified in the Basic Lease Information (the "DEVELOPMENT"). 2. TERM; POSSESSION. The term of this Lease (the "TERM") shall commence on the Commencement Date as described below and, unless sooner terminated, shall expire on the Expiration Date set forth in the Basic Lease Information (the "EXPIRATION DATE"). The "COMMENCEMENT DATE" shall be June 1, 1998. The tenant which previously leased the Building (the "Previous Tenant") has left personal property, including furniture, in the Building. In accordance with its lease, and an early lease termination agreement, the Existing Tenant is obligated to remove such personal property, and repair any damage caused by such removal, within thirty (30) days after Landlord enters into a replacement lease (such as this Lease) for the Building. Landlord agrees to use good faith efforts to cause the Previous Tenant to remove such personal property in a shorter period of time than such thirty (30) days. Landlord will repair, or cause to be repaired, any damage to the offices in the Building resulting from the removal of such personal property. 3. RENT. 3.1 BASE RENT. Tenant agrees to pay Landlord the Base Rent set forth in the Basic Lease Information, without prior notice or demand, on the first day of each and every calendar month during the Term, except that Base Rent for the first full calendar month in which Base Rent is payable shall be paid upon Tenant's execution of this Lease and Base Rent for any partial month at the beginning of the Term shall be paid on the Commencement Date. Base Rent for any partial month at the beginning or end of the Term shall be prorated based on the actual number of days in the month. If the Basic Lease Information provides for any change in Base Rent by reference to years or months (without specifying particular dates), the change will take effect on the applicable annual or monthly anniversary of the Commencement Date (which won't necessarily be the first day of a calendar month). -4- <PAGE> 8 3.2 Additional Rent: Operating Costs and Taxes. (a) Definitions. (1) "OPERATING COSTS" means all costs of managing, operating, maintaining and repairing the Project, including all costs, expenditures, fees and charges for: (A) operation, maintenance and repair of the Project (including maintenance, repair and replacement of glass, the roof covering or membrane, and landscaping); (B) utilities and services (including telecommunications facilities and equipment, recycling programs and trash removal), and associated supplies and materials; (C) compensation (including employment taxes and fringe benefits) for persons who perform duties in connection with the operation, management, maintenance and repair of the Project, such compensation to be appropriately allocated for persons who also perform duties unrelated to the Project; (D) property (including coverage for earthquake and flood if carried by Landlord), liability, rental income and other insurance relating to the Project, and expenditures for deductible amounts paid under such insurance; (E) licenses, permits and inspections; (F) complying with the requirements of any law, statute, ordinance or governmental rule or regulation or any orders pursuant thereto (collectively "LAWS"); (G) amortization of capital replacements, repairs or improvements to the Project, including capital replacements, repairs or improvements required to comply with Laws, with interest on the unamortized balance at the rate paid by Landlord on funds borrowed to finance such capital improvements (or, if Landlord finances such improvements out of Landlord's funds without borrowing, the rate that Landlord would have paid to borrow such funds, as reasonably determined by Landlord), over such useful life as Landlord shall reasonably determine in accordance with generally accepted accounting principles; (H) an office for the management of the Project, including expenses of furnishing and equipping such office and the rental value of any space occupied for such purposes; (I) property management fees reasonably charged by owners of commercial projects in the geographical area of the Project; (J) accounting, legal and other professional services incurred in connection with the operation of the Project and the calculation of Operating Costs and Taxes; (K) a reasonable allowance for depreciation on machinery and equipment used to maintain the Project and on other personal property owned by Landlord in the Project (including window coverings and carpeting in common areas); (L) contesting the validity or applicability of any Laws that may affect the Project; (M) the Project's share of any shared or common area maintenance fees and expenses (including costs and expenses of operating, managing, owning and maintaining the Parking Facility and the common areas of the Project, any fitness center in the Development, the fees and charges from the Seaport Centre Owners Association and any other fees and expenses shared with the Development); and (N) any other cost, expenditure, fee or charge, whether or not hereinbefore described, which in accordance with generally accepted property management practices would be considered an expense of managing, operating, maintaining and repairing the Project. Operating Costs for any calendar year during which average occupancy of the Project is less than one hundred percent (100%) shall be calculated based upon the Operating Costs that would have been incurred if the Project had an average occupancy of one hundred percent (100%) during the entire calendar year. Operating Costs shall not include (i) costs of special services rendered to individual tenants (including Tenant) for which a special charge is made; (ii) interest and principal payments, including penalties and late charges thereon, on loans or indebtedness secured by the Building; (iii) -5- <PAGE> 9 costs of improvements for Tenant or other tenants of the Project; (v) costs of services or other benefits of a type which are not available to Tenant but which are available to other tenants or occupants, and costs for which Landlord is reimbursed by other tenants of the Project other than through payment of tenants' shares of Operating Costs and Taxes; (vi) utility charges paid by Tenant (and other tenants in the Project) directly to the applicable public utility company; (vii) leasing commissions, attorneys' fees and other expenses incurred in connection with leasing space in the Project or enforcing such leases; (viii) depreciation or amortization, other than as specifically enumerated in the definition of Operating Costs above; and (ix) costs, fines or penalties incurred due to Landlord's violation of any Law. In no event shall the Operating Costs used by Landlord in determining Tenant's Share of Operating Costs exceed one hundred percent (100%) of the actual Operating Costs incurred by Landlord in connection with the Project, and Landlord shall not recover the costs of any items more than once. (4) "TAXES" means: all real property taxes and general, special or district assessments or other governmental impositions, of whatever kind, nature or origin, imposed on or by reason of the ownership or use of the Project; governmental charges, fees or assessments for transit or traffic mitigation (including area-wide traffic improvement assessments and transportation system management fees), housing, police, fire or other governmental service or purported benefits to the Project; personal property taxes assessed on the personal property of Landlord used in the operation of the Project; service payments in lieu of taxes and taxes and assessments of every kind and nature whatsoever levied or assessed in addition to, in lieu of or in substitution for existing or additional real or personal property taxes on the Project or the personal property described above; any increases in the foregoing caused by changes in assessed valuation, tax rate or other factors or circumstances; and the reasonable cost of contesting by appropriate proceedings the amount or validity of any taxes, assessments or charges described above. Taxes shall not include any state and federal personal or corporate income taxes measured by the income of Landlord from all sources (other than taxes on rent at the Property), as well as any franchise, inheritance, or estate, succession, gift tax, or capital levy. Landlord agrees that for the purpose of this Lease any special assessments or special taxes for public improvements to the property will be amortized, with interest at the rate payable to the assessing or taxing authority, over the maximum time Landlord is permitted to pay such special assessment or special tax without penalty. To the extent paid by Tenant or other tenants as "Tenant's Taxes" (as defined in Section 8 - Tenant's Taxes), "Tenant's Taxes" shall be excluded from Taxes. (5) TENANT'S SHARE" means the Rentable Area of the Premises divided by the total Rentable Area of the Project, as set forth in the Basic Lease Information. If the Rentable Area of the Project is changed or the Rentable Area of the Premises is changed by Tenant's leasing of additional space hereunder or for any other reason, Tenant's Share shall be adjusted accordingly. (b) Additional Rent. (1) Tenant shall pay Landlord as "ADDITIONAL RENT" for each calendar year or portion thereof during the Term Tenant's Share of the sum of (x) the amount of Operating Costs, and (y) the amount of Taxes. -6- <PAGE> 10 (2) Prior to the Commencement Date and each calendar year thereafter, Landlord shall notify Tenant of Landlord's estimate of Operating Costs, Taxes and Tenant's Additional Rent for the following calendar year (or first partial year following the Commencement Date). Commencing on the Commencement Date, and in subsequent calendar years, on the first day of January of each calendar year and continuing on the first day of every month thereafter in such year, Tenant shall pay to Landlord one-twelfth (1/12th) of the Additional Rent, as reasonably estimated by Landlord for such full calendar year. If Landlord thereafter reasonably estimates that Operating Costs or Taxes for such year will vary from Landlord's prior estimate, Landlord may, by notice to Tenant, revise the estimate for such year (and Additional Rent shall thereafter be payable based on the revised estimate). (3) As soon as reasonably practicable after the end of each calendar year, Landlord shall furnish Tenant a statement with respect to such year, showing Operating Costs, Taxes and Additional Rent for the year, and the total payments made by Tenant with respect thereto. Unless Tenant raises any objections to Landlord's statement within ninety (90) days after receipt of the same, such statement shall conclusively be deemed correct and Tenant shall have no right thereafter to dispute such statement or any item therein or the computation of Additional Rent based thereon. If Tenant does object to such statement, then Landlord shall provide Tenant with reasonable verification of the figures shown on the statement and the parties shall negotiate in good faith to resolve any disputes. Any objection of Tenant to Landlord's statement and resolution of any dispute shall not postpone the time for payment of any amounts due Tenant or Landlord based on Landlord's statement, nor shall any failure of Landlord to deliver Landlord's statement in a timely manner relieve Tenant of Tenant's obligation to pay amounts due Landlord based on Landlord's statement. (4) If Tenant's Additional Rent as finally determined for any calendar year exceeds the total payments made by Tenant on account thereof, Tenant shall pay Landlord the deficiency within twenty (20) days of Tenant's receipt of Landlord's statement. If the total payments made by Tenant on account thereof exceed Tenant's Additional Rent as finally determined for such year, Tenant's excess payment shall be credited toward the rent next due from Tenant under this Lease. For any partial calendar year at the beginning or end of the Term, Additional Rent shall be prorated on the basis of a 365-day year by computing Tenant's Share of the Operating Costs and Taxes for the entire year and then prorating such amount for the number of days during such year included in the Term. Notwithstanding the termination of this Lease, Landlord shall pay to Tenant or Tenant shall pay to Landlord, as the case may be, within twenty (20) days after Tenant's receipt of Landlord's final statement for the calendar year in which this Lease terminates, the difference between Tenant's Additional Rent for that year, as finally determined by Landlord, and the total amount previously paid by Tenant on account thereof. If for any reason Taxes for any year during the Term are reduced, refunded or otherwise changed, Tenant's Additional Rent shall be adjusted accordingly. If taxes are temporarily reduced as a result of space in the Project being leased to a tenant that is entitled to an exemption from property taxes or other taxes, then for purposes of determining Additional Rent for each year in which Taxes are reduced by any such exemption, Taxes for such year shall be calculated on the basis of the amount the Taxes for the year would have been in the absence of the exemption. The -7- <PAGE> 11 obligations of Landlord to refund any overpayment of Additional Rent and of Tenant to pay any Additional Rent not previously paid shall survive the expiration of the Term. 3.3 Payment of Rent. All amounts payable or reimbursable by Tenant under this Lease, including late charges and interest (collectively, "RENT"), shall constitute rent and shall be payable and recoverable as rent in the manner provided in this Lease. All sums payable to Landlord on demand under the terms of this Lease shall be payable within twenty (20) days after receipt of notice from Landlord of the amounts due. All rent shall be paid without offset, recoupment or deduction in lawful money of the United States of America to Landlord at Landlord's Address for Payment of Rent as set forth in the Basic Lease Information, or to such other person or at such other place as Landlord may from time to time designate. 4. SECURITY DEPOSIT. On execution of this Lease, Tenant shall deposit with Landlord the amount specified in the Basic Lease Information as the Security Deposit, if any (the "SECURITY DEPOSIT"), as security for the performance of Tenant's obligations under this Lease. Landlord may (but shall have no obligation to) use the Security Deposit or any portion thereof to cure any Event of Default under this Lease or to compensate Landlord for any damage Landlord incurs as a result of Tenant's failure to perform any of Tenant's obligations hereunder. In such event Tenant shall pay to Landlord on demand an amount sufficient to replenish the Security Deposit. If Tenant is not in default at the expiration or termination of this Lease, then within thirty (30) days after Tenant vacates the Premises Landlord shall return to Tenant the Security Deposit or the balance thereof then held by Landlord and not applied as provided above. Landlord may commingle the Security Deposit with Landlord's general and other funds. Landlord shall not be required to pay interest on the Security Deposit to Tenant. 5.

TENANT IMPROVEMENTS & ALTERATIONS. 6.1 Landlord and Tenant shall perform their respective obligations with respect to design and construction of any improvements to be constructed and installed in the Premises (the "TENANT IMPROVEMENTS"), as provided in the Construction Rider. Except for any Tenant Improvements to be constructed by Tenant as provided in the Construction rider, Tenant shall not make any alterations, improvements or changes to the Premises, including installation of any security system or telephone or data communication wiring, ("ALTERATIONS"), without Landlord's prior written consent, which consent shall not be unreasonably withheld or delayed. Notwithstanding any other provision contained herein, Tenant shall not be required to obtain Landlord's prior consent for minor, non-structural Alterations that (a) do not affect any of the Building Systems, (b) are not visible from the exterior of the Premises, and (c) cost less than Ten Thousand Dollars ($10,000), so long as Tenant gives Landlord notice of the proposed Alterations at least ten (10) days prior to commencing the Alterations and complies with all of the following provisions (except that Tenant shall not be required to obtain Landlord's approval of any plans or -11- <PAGE> 15 specifications therefor). Any such Alterations shall be completed by Tenant at Tenant's sole cost and expense: (i) with due diligence, in a good and workmanlike manner, using new materials; (ii) in compliance with plans and specifications approved by Landlord; (iii) in compliance with reasonable construction rules and regulations promulgated by Landlord from time to time; (iv) in accordance with all applicable Laws (including all work, whether structural or non-structural, inside or outside the Premises, required to comply fully with all applicable Laws and necessitated by Tenant's work); and (v) subject to all conditions which Landlord may in Landlord's discretion impose. Such conditions may include requirements for Tenant to: (i) provide payment or performance bonds or additional insurance (from Tenant or Tenant's contractors, subcontractors or design professionals); (ii) use contractors or subcontractors approved by Landlord, which approval shall not be unreasonably withheld, and use contractors designated by Landlord for Alterations affecting the structure of the Building, the Building Systems and the life safety systems of the Building; and (iii) remove all or part of the Alterations prior to or upon expiration or termination of the Term, as designated in writing by Landlord at the time Tenant requests Landlord's consent to the Alteration. If any work outside the Premises, or any work on or adjustment to any of the Building Systems, is required in connection with or as a result of Tenant's work, such work shall be performed at Tenant's expense by contractors designated by Landlord. Landlord's right to review and approve (or withhold approval of) Tenant's plans, drawings, specifications, contractors(s) and other aspects of construction work proposed by Tenant is intended solely to protect Landlord, the Property and Landlord's interests. No approval or consent by Landlord shall be deemed or construed to be a representation or warranty by Landlord as the adequacy, sufficiency, fitness or suitability thereof or compliance thereof with applicable Laws and other requirements. Except as otherwise provided in Landlord's consent, all Alterations shall upon installation become part of the realty and be the property of Landlord. 6.2 Before making any Alterations, Tenant shall submit to Landlord for Landlord's prior approval reasonably detailed final plans and specifications prepared by a licensed architect or engineer, a copy of the construction contract, including the name of the contractor and all subcontractors proposed by Tenant to make the Alterations and a copy of the contractor's license. Tenant shall reimburse Landlord upon demand for any reasonable expenses incurred by Landlord in connection with any Alterations made by Tenant, including reasonable fees charged by Landlord's contractors or consultants to review plans and specifications prepared by Tenant and to update the existing as-built plans and specifications of the Building to reflect the Alterations. Tenant shall obtain all applicable permits, authorizations and governmental approvals and deliver copies of the same to Landlord before commencement of any Alterations. 6.3 Tenant shall keep the Premises and the Project free and clear of all liens arising out of any work performed, materials furnished or obligations incurred by Tenant. If any such lien attaches to the Premises or the Project, and Tenant does not cause the same to be released by payment, bonding or otherwise within twenty (20) days after the attachment thereof, Landlord shall have the right but not the obligation to cause the same to be released, and any sums expended by Landlord (plus Landlord's reasonable administrative costs) in connection therewith shall be payable by Tenant on demand with interest thereon from the date of expenditure by Landlord at the Interest Rate (as defined in Section 16.2 - Interest). Tenant shall give Landlord at least ten (10) days' notice prior to the commencement of any Alterations and cooperate with Landlord in posting and maintaining notices of non-responsibility in connection therewith. -12- <PAGE> 16 6.4 Subject to the provisions of Section 5 - Use and Compliance with Laws and the foregoing provisions of this Section, Tenant may install and maintain furnishings, equipment, movable partitions, business equipment and other trade fixtures ("TRADE FIXTURES") in the Premises, provided that Trade fixtures do not become an integral part of the Premises or the Building. Tenant shall promptly repair any damage to the Premise or the Building caused by any installation or removal of such Trade Fixtures. 7. MAINTENANCE AND REPAIRS. 7.1 By taking possession of the Premises Tenant agrees that the Premises are then in a good and tenantable condition. Tenant shall be responsible to clean, maintain and repair the Premises, including providing janitorial services and disposal of trash; and to that end, during the Term, Tenant, at Tenant's expense but under the direction of Landlord, shall repair and maintain the Premises, including, without limitation, any elevator, the heating, ventilating and air conditioning system or systems serving the Premises, the electrical and plumbing systems serving the Premises, including the lighting and plumbing fixtures, the restrooms serving the Premises, interior stairways in the Premises, the interior and exterior glass, plate glass skylights, interior walls, floor coverings, ceiling (ceiling tiles and grid), Tenant Improvements, Alterations, fire extinguishers, outlets and fixtures, and any appliances (including dishwashers, hot water heaters and garbage disposers) in the Premises, in a first class condition, and keep the Premises in an clean, safe and orderly condition. Prior to the Commencement Date Tenant shall provide Landlord with a copy of a service contract with a licensed commercial Heating, Ventilating and Air-conditioning maintenance company (which contract and company shall be subject to Landlord's prior approval, which shall not be unreasonably withheld or delayed), to maintain, on an ongoing basis (at least quarterly), the heating, ventilating and air-conditioning system serving the Premises. Prior to the Commencement Date Landlord shall (a) re-caulk the Building, (b) repaint the exterior of the Building, (c) repair and re-coat the roof of the Building, and (d) cause the following systems (collectively, the "Building Systems") to be inspected and placed in good working order and repair: (i) electrical, (ii) plumbing, (iii) heating, ventilating and air-conditioning, and (iv) life safety systems. If, during the thirty (30) days following the Commencement date, any of the Building Systems cease being in good working order and repair, and Tenant gives Landlord written notice of such failure within such thirty (30) days following the Commencement Date, then Landlord shall cause such Building System to be placed in good working condition and repair, at no cost to Tenant. Except for any repairs and maintenance which are the responsibility of Landlord pursuant to the immediately preceding sentence, Tenant shall be responsible for all repairs and maintenance of the Building System commencing on the thirty-first (31st) day following the Commencement Date. Tenant acknowledges that the sewer piping at the Development is made of ABS plastic. Accordingly, without Landlord's prior written consent, which consent may be granted or withheld in Landlord's sole discretion, Tenant shall allow only ordinary domestic sewage to be placed in the sewer system from the Premises. UNDER NO CIRCUMSTANCES SHALL TENANT EVER PLACE, OR ALLOW TO BE PLACED, ANY ESTERS OR KETONES (USUALLY FOUND IN SOLVENTS TO CLEAN UP PETROLEUM PRODUCTS) IN THE DRAINS OR SEWER SYSTEM, FROM THE PREMISES. -13- <PAGE> 17 7.2 Landlord shall (a) maintain or cause to be maintained in reasonably good order, condition and repair, the structural portions of the roof, foundations, floors and exterior walls of the Building, and the public and common areas outside of the Building, (b) that portion of the electrical, water and sanitary sewer systems serving the Building and located outside the Building, (c) wash the exterior windows of the Building on a periodic basis, (d) caulk exterior window joints and concrete slabs and (e) paint the exterior of the Building, all of which shall be included as a part of Operating Costs, subject to the terms and conditions contained in Section 3.2 of this Lease; provided, however, if any maintenance or repair of electrical, water and sanitary sewer systems outside the Building is caused by Tenant's misuse of such system, the costs of such maintenance and repair shall not constitute a capital expenditure for the purposes of Section 3.2 of this Lease. Landlord shall be under no obligation to inspect the Premises. Tenant shall promptly report in writing to Landlord any defective condition known to Tenant which Landlord is required to repair. As a material part of the consideration for this Lease, Tenant hereby waives any benefits of any applicable existing or future law, including the provisions of California Civil Code Sections 1932(1), 1941 and 1942, that allows a tenant to make repairs at its landlord's expense. 7.3 Landlord hereby reserves the right, at any time and from time to time, without liability to Tenant, and without constituting an eviction, constructive or otherwise, or entitling Tenant to any abatement of rent or to terminate this Lease or otherwise releasing Tenant from any of Tenant's obligations under this Lease: (a) To make alterations, additions, repairs, improvements to or in or to decrease the size of area of, all or any part of the Building, the fixtures and equipment therein, and the Building Systems (except that Landlord shall not have any right under this provision to materially reduce the size of the Building, or permanently, materially and adversely affect Tenant's access to and use of the Premises, except only as may be required to comply with Laws or as a result of any fire or other casualty, or Condemnation); (b) To change the Building's name or street address; (c) To install and maintain any and all signs on the exterior and interior of the Building; (d) To reduce, increase, enclose or otherwise change at any time and from time to time the size, number, location, lay-out and nature of the common areas (including the Parking Facility) and other tenancies and premises in the Property and to create additional rentable areas through use or enclosure of common areas; and (e) If any governmental authority promulgates or revises any Law or imposes mandatory or voluntary controls or guidelines on Landlord or the Property relating to the use or conservation of energy or utilities or the reduction of automobile or other emissions or reduction or management of traffic or parking on the Property (collectively "CONTROLS"), to comply with such Controls, whether mandatory or voluntary, or make any alterations to the Property related thereto. -14- <PAGE> 18 (f) In exercising its rights under this Section 7.3, Landlord agrees to use reasonable efforts to minimize any interruption or disruption of Tenant's use of the Premises. 8. TENANT'S TAXES. "TENANT'S TAXES" shall mean (a) all taxes, assessments, license fees and other governmental charges or impositions levied or assessed against or with respect to Tenant's personal property or Trade Fixtures in the Premises, whether any such imposition is levied directly against Tenant or levied against Landlord or the Property, (b) all rental, excise, sales or transaction privilege taxes arising out of this Lease (excluding, however, state and federal personal or corporate income taxes measured by the income of Landlord from all sources) imposed by any taxing authority upon Landlord or upon Landlord's receipt of any rent payable by Tenant pursuant to the terms of this Lease ("RENTAL TAX"), and (c) any increase in Taxes attributable to inclusion of a value placed on Tenant's personal property, Trade Fixtures or Alterations. Tenant shall pay any Rental Tax to Landlord in addition to and at the same time as Base Rent is payable under this Lease, and shall pay all other Tenant's Taxes before delinquency (and, at Landlord's request, shall furnish Landlord satisfactory evidence thereof). If Landlord pays Tenant's Taxes or any portion thereof, Tenant shall reimburse Landlord upon demand for the amount of such payment, together with interest at the Interest Rate from the date of Landlord's payment to the date of Tenant's reimbursement. 9. UTILITIES. 9.2 Payment for Utilities and Services. (a) If the temperature otherwise maintained in any portion of the Premises by the HVAC systems of the Building is affected as a result of any lights, machines or equipment used by Tenant in the Premises, then Landlord shall have the right to install any machinery or equipment reasonably necessary to restore the temperature, including modifications to the standard air-conditioning equipment. The cost of any such equipment and modifications, including the cost of installation and any additional cost of operation and maintenance of the same, shall be paid by Tenant to Landlord upon demand. (b) Electricity, water, sanitary sewer and any gas will be separately metered for the Premises. Tenant shall pay prior to delinquency all charges for water, gas, electricity, telephone and other telecommunication services, janitorial service, trash pick-up, sewer and all other services consumed on or supplied to the Premises, and all taxes, levies, fee and surcharges thereon. 9.3 Interruption of Services. In the event of an interruption in or failure or inability to provide any services or utilities to the Premises or Building for any reason (a "SERVICE FAILURE"), such Service Failure shall not, regardless of its duration, impose upon Landlord any liability whatsoever, constitute an eviction of Tenant, constructive or otherwise, entitle Tenant to an abatement of rent or to terminate this Lease or otherwise release Tenant from any of Tenant's obligations under this Lease. Tenant hereby waives any benefits of any applicable existing or future Law, including the provisions of California Civil Code Section 1932(1), permitting the termination of this Lease due to such interruption, failure or inability. -15- <PAGE> 19 10. EXCULPATION AND INDEMNIFICATION. 10.1 Landlord's Indemnification of Tenant. Landlord shall indemnify, protect, defend and hold Tenant harmless from and against any claims, actions, liabilities, damages, costs or expenses, including reasonable attorneys' fees and costs incurred in defending against the same ("CLAIMS") asserted by any third party against Tenant for loss, injury or damage, to the extent such loss, injury or damage is caused by the willful misconduct or negligent acts or omissions of Landlord or its authorized representatives. 10.2 Tenant's Indemnification of Landlord.

Landlord shall not be liable to Tenant for any loss, injury or other damage to Tenant or to Tenant's property in or about the Premises or the Property from any cause (including defects in the Property or in any equipment in the Property; fire, explosion or other casualty; bursting, rupture, leakage or overflow of any plumbing or other pipes or lines, sprinklers, tanks, drains, drinking fountains or washstands in, above, or about the Premises or the Property; or acts of other tenants in the Property). Tenant hereby waives all claims against Landlord for any such loss, injury or damage and the cost and expense of defending against claims relating thereto, including any loss, injury or damage caused by Landlord's negligence (active or passive) or willful misconduct. Notwithstanding any other provision of this Lease to the contrary, in no event shall Landlord or Tenant be liable to the other party for any punitive or consequential damages or damages for loss of business by Tenant or Landlord except for any liability which Tenant might have for holding over in the Premises beyond the expiration of the Term in accordance with the provisions of Section 19.2 of this Lease. 10.4 Survival. The obligations of the parties under this Section 10 shall survive the expiration or termination of this Lease. 11. INSURANCE. 11.1 Tenant's Insurance. (a) Liability Insurance.

Each policy of liability insurance required by this Section shall: (i) contain a cross liability endorsement or separation of insureds clause; (ii) provide that any waiver of subrogation rights or release prior to a loss does not void coverage; (iii) provide that it is primary to and not contributing with, any policy of insurance carried by Landlord covering the same loss; (iv) provide that any failure to comply with the reporting provisions shall not affect coverage provided to Landlord, its partners, property managers and Mortgagees; and (v) name Landlord, its partners, the Property Manager identified in the Basic Lease Information (the "PROPERTY MANAGER"), and such other parties in interest as Landlord may from time to time reasonably designate to Tenant in writing, as additional insureds. Such additional insureds shall be provided at least the same extent of coverage as is provided to Tenant under such policies. All endorsements effecting such additional insureds status shall be at least as broad as additional insured endorsement form number CG 20 11 11 85 promulgated by the Insurance Services Office. (b) Property Insurance. Tenant shall at all times maintain in effect with respect to any Alterations and Tenant's Trade Fixtures and personal property, commercial property insurance providing coverage, on an "all risk" or "special form" basis, in an amount equal to at least 90% of the full replacement cost of the covered property. Tenant may carry such insurance under a blanket policy provided that such policy provides coverage equivalent to a separate policy. During the Term, the proceeds from any such policies of insurance shall be used for the repair or replacement of the Alterations, Trade Fixtures and personal property so insured. Landlord shall be provided coverage under such insurance to the extent of its insurable interest and, if requested by Landlord, both Landlord and Tenant shall sign all documents reasonably necessary or proper in connection with the settlement of any claim or loss under such insurance. Landlord will have no obligation to carry insurance on any Alterations or on Tenant's Trade Fixtures or personal property. (c) Requirements For All Policies. Each policy of insurance required under this Section 11.1 shall: (i) be in a form, and written by an insurer, reasonably acceptable to Landlord, (ii) be maintained at Tenant's sole cost and expense, and (iii) require at least thirty (30) days' written notice to Landlord prior to any cancellation, nonrenewal or modification of insurance coverage.

Tenant shall increase the amounts of insurance as required by any Mortgage, and, not more frequently than once every three (3) years, as recommended by Landlord's insurance broker, if, in the reasonable opinion of either of them, the amount of insurance then required under this Lease is not adequate. (e) Certificates of Insurance. Prior to occupancy of the Premises by Tenant, and not less than thirty (30) days prior to expiration of any policy thereafter, Tenant shall furnish to Landlord a certificate of insurance reflecting that the insurance required by this Section is in force, accompanied by an endorsement showing the required additional insureds satisfactory to Landlord in substance and form. Notwithstanding the requirements of this paragraph, Tenant shall at Landlord's request provide to Landlord a certified copy of each insurance policy required to be in force at any time pursuant to the requirements of this Lease or its Exhibits. 11.2 Landlord's Insurance. During the Term, to the extent such coverages are available at a commercially reasonable cost, Landlord shall maintain in effect insurance on the Building with responsible insurers, on an "all risk" or "special form" basis, insuring the Building and the Tenant Improvements in an amount equal to at least 90% of the replacement cost thereof, excluding land, foundations, footings and underground installations. Landlord may, but shall not be obligated to, carry insurance against additional perils and/or in greater amounts. Landlord shall maintain in full force throughout the Term, commercial general liability insurance providing coverage with limits of not less than Two Million Dollars ($2,000,000.00) each occurrence for bodily injury and property damage combined covering the Property (the cost of premiums for which shall be included in Operating costs). 11.3 Mutual Waiver of Right of Recovery & Waiver of Subrogation. Landlord and Tenant each hereby waive any right of recovery against each other and the partners, managers, members, shareholders, officers, directors and authorized representatives of each other for any loss or damage that is covered by any policy of property insurance maintained by either party (or required by this lease to be maintained) with respect to the Premises or the Property or any operation therein, regardless of cause, including negligence (active or passive) of the party benefiting from the waiver. If any such policy of insurance relating to this Lease or to the Premises or the Property does not permit the foregoing waiver or if the coverage under any such policy would be invalidated as a result of such waiver, the party maintaining such policy shall obtain from the insurer under such policy a waiver of all right of recovery by way of subrogation against either party in connection with any claim, loss or damage covered by such policy. 12. DAMAGE OR DESTRUCTION. 12.1 Landlord's Duty to Repair. (a) If all or a substantial part of the Premises are rendered untenantable or inaccessible by damage to all or any part of the Property from fire or other casualty then, unless either party is entitled to and elects to terminate this lease pursuant to Sections 12.2 - Landlord's Right to Terminate and 12.3 - Tenant's Right to Terminate, Landlord shall, at its expense, use reasonable efforts to repair and restore the Premises and/or the Property, as the case may be, to substantially their former condition to the extent permitted by then applicable Laws; provided, -18- <PAGE> 22 however, in no event shall Landlord have any obligation for repair or restoration: (i) beyond the extent of the sum of (x) the insurance proceeds received by Landlord for such repair or restoration plus (y) $10,000, or (ii) for any of Tenant's personal property, Trade Fixtures or Alterations. (b) If Landlord is required or elects to repair damage to the Premises and/or the Property, this Lease shall continue in effect, but Tenant's Base Rent and Additional Rent shall be abated with regard to any portion of the Premises that Tenant is prevented from using by reason of such damage or its repair from the date of the casualty until substantial completion of Landlord's repair of the affected portion of the Premises as required under this Lease. In no event shall Landlord be liable to Tenant by reason of any injury to or interference with Tenant's business or property arising from fire or other casualty or by reason of any repairs to any part of the Property necessitated by such casualty. 12.2 Landlord's Right to Terminate. Landlord may elect to terminate this Lease following damage by fire or other casualty under the following circumstances: (a) If, in the reasonable judgment of Landlord, the Premises and the Property cannot be substantially repaired and restored under applicable Laws within one (1) year from the date of the casualty; (b) If, in the reasonable judgment of Landlord, adequate proceeds are not, for any reason (except for Landlord's failure to maintain the insurance coverage required to be maintained by Landlord under this Lease), made available to Landlord from Landlord's insurance policies (and/or from Landlord's funds made available for such purpose, at Landlord's sole option) to make the required repairs; (c) If the Building is damaged or destroyed to the extent that, in the reasonable judgment of Landlord, the cost to repair and restore the Building would exceed twenty-five percent (25%) of the full replacement cost of the Building, whether or not the Premises are at all damaged or destroyed; or (d) If the fire or other casualty occurs during the last year of the Term. If any of the circumstances described in subparagraphs (a), (b), (c) or (d) of this Section 12.2 occur or arise, Landlord shall give Tenant notice within one hundred and twenty (120) days after the date of the casualty, specifying whether Landlord elects to terminate this Lease as provided above and, if not, Landlord's estimate of the time required to complete Landlord's repair obligations under this Lease. 12.3 Tenant's Right to Terminate. If all or a substantial part of the Premises are rendered untenantable or inaccessible by damage to all or any part of the Property from fire or other casualty, and Landlord does not elect to terminate as provided above, then Tenant may elect to terminate this Lease if Landlord's estimate of the time required to complete Landlord's repair obligations under this Lease is greater than one (1) year, in which event Tenant may elect to terminate this Lease by giving Landlord notice of such election to terminate within thirty (30) days after Landlord's notice to Tenant pursuant to Section 12.2 - Landlord's Right to Terminate. -19- <PAGE> 23 12.4 Waiver. Landlord and Tenant each hereby waive the provisions of California Civil Code Sections 1932(2), 1933(4) and any other applicable existing or future Law permitting the termination of a lease agreement in the event of damage or destruction under any circumstances other than as provided in Sections 12.2 - Landlord's Right to Terminate and 12.3 - Tenant's Right to Terminate. 13. CONDEMNATION. 13.1 Definitions. (a) "AWARD" shall mean all compensation, sums, or anything of value awarded, paid or received on a total or partial Condemnation. (b) "CONDEMNATION" shall mean (i) a permanent taking (or a temporary taking for a period extending beyond the end of the Term) pursuant to the exercise of the power of condemnation or eminent domain by any public or quasi-public authority, private corporation or individual having such power ("CONDEMNOR"), whether by legal proceedings or otherwise, or (ii) a voluntary sale or transfer by Landlord to any such authority, either under threat of condemnation or while legal proceedings for condemnation are pending. (c) "DATE OF CONDEMNATION" shall mean the earlier of the date that title to the property taken is vested in the Condemnor or the date the Condemnor has the right to possession of the property being condemned. 13.2 Effect on Lease. (a) If more than one-third (1/3) of the Premises is taken by Condemnation, this Lease shall terminate as of the Date of Condemnation. If one-third (1/3) or less of the Premises is taken by Condemnation, this Lease shall remain in effect; provided, however, that if the portion of the Premises remaining after the Condemnation will be unsuitable for Tenant's continued use, then upon notice to Landlord within thirty (30) days after Landlord notifies Tenant of the Condemnation, Tenant may terminate this Lease effective as of the Date of Condemnation. (b) If twenty-five percent (25%) or more of the Project or of the parcel(s) of land on which the Building is situated or of the Parking Facility or of the floor area in the Building is taken by Condemnation, or if as a result of any Condemnation the Building is not longer reasonably suitable for use as an office building, whether or not any portion of the Premises is taken, Landlord may elect to terminate this Lease, effective as of the Date of Condemnation, by notice to Tenant within thirty (30) days after the Date of Condemnation. (c) If all or a portion of the Premises is temporarily taken by a Condemnor for a period not extending beyond the end of the Term, this Lease shall remain in full force and effect. 13.3 Restoration. If this Lease is not terminated as provided in Section 13.2 - Effect on Lease, Landlord, at its expense, shall diligently proceed to repair and restore the Premises to -20- <PAGE> 24 substantially its former condition (to the extent permitted by then applicable Laws) and/or repair and restore the Building to an architecturally complete office building; provided, however, that Landlord's obligations to so repair and restore shall be limited to the amount of any Award received by Landlord and not required to be paid to any Mortgagee (as defined in Section 20.2 below). In no event shall Landlord have any obligation to repair or replace any improvements in the Premises beyond the amount of any Award received by Landlord for such repair or to repair or replace any of Tenant's personal property, Trade Fixtures, or Alterations. 13.4 Abatement and Reduction of Rent. If any portion of the Premises is taken in a Condemnation or is rendered permanently untenantable by repairs necessitated by the Condemnation, and this Lease is not terminated, the Base Rent and Additional Rent payable under this Lease shall be proportionally reduced as of the Date of Condemnation based upon the percentage of rentable square feet in the Premises so taken or rendered permanently untenantable. In addition, if this Lease remains in effect following a Condemnation and Landlord proceeds to repair and restore the Premises, the Base Rent and Additional Rent payable under this Lease shall be abated during the period of such repair or restoration to the extent such repairs prevent Tenant's use of the Premises. 13.5 Awards. Any Award made shall be paid to Landlord, and Tenant hereby assigns to Landlord, and waives all interest in or claim to, any such Award, including any claim for the value of the unexpired Term; provided, however, that Tenant shall be entitled to receive, or to prosecute a separate claim for, an Award for a temporary taking of the Premises or a portion thereof by a Condemnor where this Lease is not terminated (to the extent such Award relates to the unexpired Term), or an Award or portion thereof separately designated for relocation and moving expenses or the interruption of or damage to Tenant's business or as compensation for Tenant's personal property, Trade Fixtures or Alterations. 13.6 Waiver. Landlord and Tenant each hereby waive the provisions of California Code of Civil Procedure Section 1265.130 and any other applicable existing or future Law allowing either party to petition for a termination of this Lease upon a partial taking of the Premises and/or the Property. 14. ASSIGNMENT AND SUBLETTING. 14.1 Landlord's Consent Required. Tenant shall not assign this Lease or any interest therein, or sublet or license or permit the use or occupancy of the Premises or any part thereof by or for the benefit of anyone other than Tenant, or in any other manner transfer all or any part of Tenant's interest under this Lease (each and all a "TRANSFER"), without the prior written consent of Landlord, which consent (subject to the other provisions of this Section 14) shall not be unreasonably withheld. If Tenant is a business entity, any direct or indirect transfer of fifty percent (50%) or more of the ownership interest of the entity (whether in a single transaction or in the aggregate through more than one transaction) shall be deemed a Transfer. A public offering of Tenant's stock shall not constitute a Transfer under the provisions of this Lease. Notwithstanding any provision in this Lease to the contrary, Tenant shall not mortgage, pledge, hypothecate or otherwise encumber this Lease or all or any party of Tenant's interest under this Lease. -21- <PAGE> 25 14.2 Reasonable Consent. (a) Prior to any proposed Transfer, Tenant shall submit in writing to Landlord (i) the name and legal composition of the proposed assignee, subtenant, user or other transferee (each a "PROPOSED TRANSFEREE"); (ii) the nature of the business proposed to be carried on in the premises; (iii) a current balance sheet, income statements for the last two years and such other reasonable financial and other information concerning the Proposed Transferee as Landlord may request; and (iv) a copy of the proposed assignment, sublease or other agreement governing the proposed Transfer. Within fifteen (15) Business Days after Landlord receives all such information it shall notify Tenant whether it approves or disapproves such Transfer or if it elects to proceed under Section 14.7 - Landlord's Right to Space. (b) Tenant acknowledges and agrees that, among other circumstances for which Landlord could reasonably withhold consent to a proposed Transfer, it shall be reasonable for Landlord to withhold consent where (i) the Proposed Transferee does not intend itself to occupy the entire portion of the Premises assigned or sublet, (ii) Landlord reasonably disapproves of the Proposed Transferee's business operating ability or history, reputation or creditworthiness or the nature or character of the business to be conducted by the Proposed Transferee at the Premises, (iii) the Proposed Transferee is a governmental agency or unit or an existing tenant in the Project, unless, in the case of an existing tenant, Landlord does not have space available for lease containing the same or more square feet as is contained in the Premises to accommodate the existing tenant's expansion or renewal in the Project, (iv) the proposed Transfer would violate any "exclusive" rights of any tenants in the Project, (v) Landlord or Landlord's agent has shown space in the Project to the Proposed Transferee or responded to any inquiries from the Proposed Transferee or the Proposed Transferee's agent concerning availability of space in the Project, at any time within the preceding six months, or (vi) Landlord otherwise determines that the proposed Transfer would have the effect of materially decreasing the financial value of the Project or increasing the expenses associated with operating, maintaining and repairing the Project. In no event may Tenant publicly advertise all or any portion of the Premises for assignment or sublease at a rental less than that then sought by Landlord for a direct lease (non-sublease) of comparable space in the Project. Notwithstanding the foregoing, Tenant may employ a broker who advertises on a commercial multiple listing service in order to offer the Premises for assignment or sublease. 14.3 Excess Consideration. If Landlord consents to the Transfer, Landlord shall be entitled to receive as Additional Rent hereunder, fifty percent (50%) of all "Sublease Profits" (as defined below). "Sublease Profits" shall mean any consideration paid by the Transferee for the assignment or sublease and, in the case of a sublease, the excess of the rent and other consideration payable by the subtenant over the amount of Base Rent and Additional Rent payable hereunder applicable to the subleased space, less any and all direct, out-of-pocket expenses and cash concessions, including costs for necessary Alterations, attorneys' fees (not to exceed One Thousand and 00/100 Dollars [$1,000.000] in attorneys' fees) and brokerage commission, paid by Tenant to procure the assignee or subtenant. Tenant shall pay to Landlord as additional rent, within twenty (20) days after receipt by Tenant, any such excess consideration paid by any transferee (the "TRANSFEREE") for the Transfer provided any capital expenditures and brokerage commissions in connection with any sublease shall be amortized over the term of the sublease. -22- <PAGE> 26 14.4 No Release Of Tenant. No consent by Landlord to any Transfer shall relieve Tenant of any obligations to be performed by Tenant under this Lease, whether occurring before or after such consent, assignment, subletting or other Transfer. Each Transferee shall be jointly and severally liable with Tenant (and Tenant shall be jointly and severally liable with each Transferee) for the payment of rent (or, in the case of a sublease, rent in the amount set forth in the sublease) and for the performance of all other terms and provisions of this Lease. The consent by Landlord to any Transfer shall not relieve Tenant or any such Transferee from the obligation to obtain Landlord's express prior written consent to any subsequent Transfer by Tenant or any Transferee. The acceptance of rent by Landlord from any other person (whether or not such person is an occupant of the Premises) shall not be deemed to be a waiver by Landlord of any provision of this Lease or to be a consent to any Transfer. 14.5 Expenses and Attorney's Fees. Tenant shall pay to Landlord on demand all costs and expenses (including reasonable attorneys' fees not to exceed One Thousand and 00/100 Dollars [$1,000.00] for each request for Landlord's consent to a proposed Transfer) incurred by Landlord in connection with reviewing or consenting to any proposed Transfer (including any request for consent to, or any waiver of Landlord's rights in connection with, any security interest in any of Tenant's property at the Premises). 14.6 Effectiveness of Transfer. Prior to the date on which any permitted Transfer (whether or not requiring Landlord's consent) becomes effective, Tenant shall deliver to Landlord a counterpart of the fully executed Transfer document and Landlord's standard form of Consent to Assignment or Consent to Sublease executed by Tenant and the Transferee in which each of Tenant and the Transferee confirms its obligations pursuant to this Lease. Failure or refusal of a Transferee to execute any such instrument shall not release or discharge the Transferee from liability as provided herein. The voluntary, involuntary or other surrender of this Lease by Tenant, or a mutual cancellation by Landlord and Tenant, shall not work a merger, and any such surrender or cancellation shall, at the option of Landlord, either terminate all or any existing subleases or operate as an assignment to Landlord of any or all of such subleases. 14.7 Landlord's Right to Space. Notwithstanding any of the above provisions of this Section to the contrary, if Tenant notifies Landlord that it desires to enter into a Transfer, Landlord, in lieu of consenting to such Transfer, may elect(x) in the case of an assignment or a sublease of the entire Premises, to terminate this Lease, or (y) in the case of a sublease of less than the entire Premises, to terminate this Lease as it relates to the space proposed to be subleased by Tenant. In such event, this Lease will terminate (or the space proposed to be subleased will be removed from the Premises subject to this Lease and the Base Rent and Tenant's Share under this Lease shall be proportionately reduced) on the date the Transfer was proposed to be effective, and Landlord may lease such space to any party, including the prospective Transferee identified by Tenant. Landlord acknowledges that within twelve (12) months following the Commencement Date Tenant intents to sublease up to 15,000 rentable square feet on the ground floor of the Premises, and, notwithstanding the provisions of this Section 14.7 to the contrary, Landlord shall not have the right to terminate this Lease as it relates to Tenant subleasing up to 15,000 rentable square feet on the ground floor of the Premises during the initial twelve (12) months following the Commencement Date. Notwithstanding the provisions of this Section 14.7 to the contrary, if (i) Tenant proposes to assign this Lease, or to sublease all or a portion of the Premises, and (ii) Landlord notifies Tenant -23- <PAGE> 27 that Landlord elects to terminate this Lease due to such proposed assignment, or Landlord elects to terminate this Lease with respect to the space Tenant proposes to sublease, then Tenant shall have the right to rescind any such termination by Landlord by giving Landlord written notice ("Tenant's Rescission Notice") only within five (5) Business Days following Landlord's written notice of termination pursuant to the provisions of this Section 14.7. Upon Tenant giving Tenant's Rescission Notice, (iii) this Lease shall remain in full force and effect in accordance with the provisions contained herein, and (iv) Tenant shall be deemed to have withdrawn the request for consent to a Transfer, and the proposed Transfer which was the basis for Landlord's termination under the provisions of this Section 14.7 shall be void, and of no force and effect. 14.8 Assignment of Sublease Rents. Tenant hereby absolutely and irrevocably assigns to Landlord any and all rights to receive rent and other consideration from any sublease and agrees that Landlord, as assignee or as attorney-in-fact for Tenant solely for purposes of collecting rent and other consideration from any sublessee, or a receiver for Tenant appointed on Landlord's application may (but shall not be obligated to) collect such rents and other consideration and apply the same toward Tenant's obligations to Landlord under this Lease; provided, however, that Landlord grants to Tenant at all times prior to occurrence of any breach or default by Tenant a revocable license to collect such rents (which license shall automatically and without notice be and be deemed to have been revoked and terminated immediately upon any Event of Default). 14.9 Transfer to Affiliate. Notwithstanding any provision contained in the Section 14 to the contrary, Tenant shall have the right, without the consent of Landlord, upon ten (10) days prior written notice to Landlord, to transfer Tenant's interest in this Lease to an "Affiliate" of Tenant, and the provisions of Sections 14.2, 14.3 and 14.7 shall not apply with respect to the transfer to the Affiliate, but the transfer to the Affiliate shall be subject to all other terms and conditions of this Lease, including the provisions of this Section 14.9. Tenant shall remain liable under this Lease after any such transfer. For the purposes of this Article 14, the term "Affiliate" of Tenant shall mean and refer to any entity controlling, controlled by or under common control with Tenant or Tenant's parent, as the case may be, or any corporation or other entity resulting from a merger or consolidation with Tenant, or to any person or entity which acquires at least ninety percent (90%) of all the assets of Tenant as a going concern. "Control" as used herein shall mean the possession, direct or indirect, of the power to direct or cause the direction of the management and policies of such controlled entity; and the ownership, or possession of the right to vote, in the ordinary direction of its affairs, of at least fifty percent (50%) of the voting interest in any entity. Notwithstanding Tenant's right to Transfer to an Affiliate pursuant to the provisions of this Section 14.9, Tenant may not, through use of its rights under this Article 14 in two or more transactions (whether separate transactions or steps or phases of a single transaction), at one time or over time, whether by first assigning this Lease to a subsidiary and then merging the subsidiary into another entity or selling the stock of the subsidiary or by other means, assign or sublease the Premises, or transfer control of Tenant, to any person or entity which is not a subsidiary, affiliate or controlling corporation of the original Tenant, as then constituted, existing prior to the commencement of such transactions, without first obtaining Landlord's prior written consent pursuant to the provisions of Section 14.2. -24- <PAGE> 28 15. DEFAULT AND REMEDIES. 15.1 Events of Default. The occurrence of any of the following shall constitute an "EVENT OF DEFAULT" by Tenant: (a) Tenant fails to make any payment of rent when due, or any amount required to replenish the security deposit as provided in Section 4 above, if payment in full is not received by Landlord within three (3) days after written notice that it is due. (b) Tenant abandons the Premises, together with Tenant's failure to pay Rent when due. (c) Tenant fails timely to deliver any subordination document, estoppel certificate or financial statement requested by Landlord within the applicable time period specified in Sections 20 - Encumbrances - and 21 - Estoppel Certificates and Financial Statements - below. (d) Tenant violates the restrictions on Transfer set forth in Section 14 - Assignment and Subletting. (e) Tenant ceases doing business as a going concern; makes an assignment for the benefit of creditors; is adjudicated an insolvent, files a petition (or files an answer admitting the material allegations of a petition) seeking relief under any state or federal bankruptcy or other statute, law or regulation affecting creditors' rights; all or substantially all of Tenant's assets are subject to judicial seizure or attachment and are not released within 60 days, or Tenant consents to or acquiesces in the appointment of a trustee, receiver or liquidator for Tenant or for all or any substantial part of Tenant's assets. (f) Tenant fails, within ninety (90) days after the commencement of any proceedings against Tenant seeking relief under any state or federal bankruptcy or other statute, law or regulation affecting creditors' rights, to have such proceedings dismissed, or Tenant fails, within ninety (90) days after an appointment, without Tenant's consent or acquiescence, of any trustee, receiver or liquidator for Tenant or for all or any substantial part of Tenant's assets, to have such appointment vacated. (g) Tenant fails to perform or comply with any provision of this Lease other than those described in (a) through (f) above, and does not fully cure such failure within thirty (30) days after notice to Tenant or, if such failure cannot be cured within such thirty (30)-day period, Tenant fails within such thirty (30)-day period to commence, and thereafter diligently proceed with, all actions necessary to cure such failure as soon as reasonably possible but in all events within one hundred twenty (120) days of such notice; provided, however, that if Landlord in Landlord's reasonable judgment determines that such failure will not be cured by Tenant within such one hundred twenty (120) days, then such failure shall constitute an Event of Default immediately upon such notice to Tenant. -25- <PAGE> 29 15.2 Remedies. Upon the occurrence of an Event of Default, Landlord shall have the following remedies, which shall not be exclusive but shall be cumulative and shall be in addition to any other remedies now or hereafter allowed by law: (a) Landlord may terminate Tenant's right to possession of the Premises at any time by written notice to Tenant. Tenant expressly acknowledges that in the absence of such written notice from Landlord, no other act of Landlord, including re-entry into the Premises, efforts to relet the Premises, relettting of the Premises for Tenant's account, storage of Tenant's personal property and Trade Fixtures, acceptance of keys to the Premises from Tenant or exercise of any other rights and remedies under this Section, shall constitute an acceptance of Tenant's surrender of the Premises or constitute a termination of this Lease or of Tenant's right to possession of the Premises. Upon such termination in writing of Tenant's right to possession of the Premises, as herein provided, this Lease shall terminate and Landlord shall be entitled to recover damages from Tenant as provided in California Civil Code Section 1951.2 and any other applicable existing or future Law providing for recovery of damages for such breach, including the worth at the time of award of the amount by which the rent which would be payable by Tenant hereunder for the remainder of the Term after the date of the award of damages, including Additional Rent as reasonably estimated by Landlord, exceeds the amount of such rental loss as Tenant proves could have been reasonably avoided, discounted at the discount rate published by the Federal Reserve Bank of San Francisco for member banks at the time of the award plus one percent (1%). (b) Landlord shall have the remedy described in California Civil Code Section 1951.4 (Landlord may continue this Lease in effect after Tenant's breach and abandonment and recover rent as it becomes due, if Tenant has the right to sublet or assign, subject only to reasonable limitations). (c) Landlord may cure the Event of Default at Tenant's expense. If Landlord pays any sum or incurs any expense in curing the Event of Default, Tenant shall reimburse Landlord upon demand for the amount of such payment or expense with interest at the Interest Rate from the date the sum is paid or the expense is incurred until Landlord is reimbursed by Tenant. (d) Landlord may remove all Tenant's property from the Premises, and such property may be stored by Landlord in a public warehouse or elsewhere at the sole cost and for the account of Tenant. If Landlord does not elect to store any or all of Tenant's property left in the Premises, Landlord may consider such property to be abandoned by Tenant, and Landlord may thereupon dispose of such property in any manner deemed appropriate by Landlord. Any proceeds realized by Landlord on the disposal of any such property shall be applied first to offset all expenses of storage and sale, then credited against Tenant outstanding obligations to Landlord under this Leas, and any balance remaining after satisfaction of all obligations of Tenant under this Lease shall be delivered to Tenant. 16. LATE CHARGE AND INTEREST. 16.1 Late Charge. If any payment of rent is not received by Landlord within five (5) days after written notice from Landlord to Tenant that the payment is past due, Tenant shall pay to Landlord on demand as a late charge an additional amount equal to four percent (4%) of the -26- <PAGE> 30 overdue payment; provided, however, if Landlord has given Tenant written notice two (2) or more times in any consecutive twelve (12) month period that a payment of rent is past due, then Tenant shall pay to Landlord on demand commencing with the third (3rd) part due payment in any twelve (12) month period, and continuing with each past due payment thereafter in such twelve (12) month period, as a late charge an additional amount equal to four percent (4%) of the overdue payment without any requirement of additional notice that such payment is past due. A late charge shall not be imposed more than once on any particular installment not paid when due, but imposition of a late charge on any payment not made when due does not eliminate or supersede late charges imposed on other (prior) payments not made when due or preclude imposition of a late charge on other installments or payments not made when due. 16.2 Interest. In addition to the late charges referred to above, which are intended to defray Landlord's costs resulting from late payments, any payment from Tenant to Landlord not paid when due shall at Landlord's option bear interest from the date due until paid to Landlord by Tenant at the rate of fifteen percent (15%) per annum or the maximum lawful rate that Landlord may charge to Tenant under applicable laws, whichever is less (the "INTEREST RATE"). Acceptance of any late charge and/or interest shall not constitute a waiver of Tenant's default with respect to the overdue sum or prevent Landlord from exercising any of its other rights and remedies under this Lease. 17. WAIVER. No provisions of this Lease shall be deemed waived by either party unless such waiver is in a writing signed by the waiving party. The waiver by either party of any breach of any provision of this Lease shall not be deemed a waiver of such provision or of any subsequent breach of the same or any other provision of this Lease. No delay or omission in the exercise of any right or remedy of either party upon any default by the other party shall impair such right or remedy or be construed as a waiver. Landlord's acceptance of any payments of rent due under this Lease shall not be deemed a waiver of any default by Tenant under this Lease (including Tenant's recurrent failure to timely pay rent) other than Tenant's nonpayment of the accepted sums, and no endorsement or statement on any check or on any letter accompanying any check or payment shall be deemed an accord and satisfaction. The consent to or approval by either party of any act by the other party requiring the first party's consent or approval shall not be deemed to waive or render unnecessary the consenting or approving party's consent to or approval of any subsequent act by the other party. 18. ENTRY, INSPECTION AND CLOSURE. Upon reasonable oral or written notice to Tenant (and without notice in emergencies), Landlord and its authorized representatives may enter the Premises at all reasonable times to: (a) determine whether the Premises are in good condition, (b) determine whether Tenant is complying with its obligations under this Lease, (c) perform any maintenance or repair of the Premises or the Building that Landlord has the right or obligation to perform, (d) install or repair improvements for other tenants where access to the Premises is required for such installation or repair, (e) serve, post or keep posted any notices required or allowed under the provisions of this Lease, (f) show the Premises to prospective brokers, agents, buyers, transferees, or Mortgagees, or (g) do any other act or thing necessary for the safety or preservation of the Premises or the Building. In addition, Landlord shall show the Premises to prospective tenants upon prior reasonable oral or notice to Tenant during the last twelve (12) months of the Term. When reasonably necessary Landlord may temporarily close entrances, doors, -27- <PAGE> 31 corridors, elevators or other facilities in the Building without liability to Tenant by reason of such closure. Landlord shall conduct its activities under this Section in a manner that will minimize inconvenience to Tenant without incurring additional expense to Landlord. In no event shall Tenant be entitled to an abatement of rent on account of any entry by Landlord, and Landlord shall not be liable in any manner for any inconvenience, loss of business or other damage to Tenant or other persons arising out of Landlord's entry on the Premises in accordance with this Section. No action by Landlord pursuant to this paragraph shall constitute an eviction of Tenant, constructive or otherwise, entitle Tenant to an abatement of rent or to terminate this Lease or otherwise release Tenant from any of Tenant's obligations under this Lease. 19. SURRENDER AND HOLDING OVER. 19.1 Surrender. Upon the expiration or termination of this Lease, Tenant shall surrender the Premises and all Tenant Improvements and Alternations to Landlord broom-clean and in good condition, except for reasonable wear and tear, damage from casualty or condemnation and any changes resulting from approved Alterations; provided, however, that on or before the expiration or termination of this Lease Tenant shall remove all telephone and other cabling installed in this Building by Tenant and remove from the Premises all Tenant's personal property and any Trade Fixtures and all Alternations that Landlord has elected to require Tenant to remove as provided in Section 6.1 - Tenant Improvements & Alterations, and repair any damage caused by such removal; provided, however, upon expiration or termination of this Lease Tenant shall not be obligated to remove any Hazardous Material from the Property unless Handled by Tenant at the Property. If such removal is not completed on or before the expiration or termination of the Term, Landlord shall have the right (but no obligation) to remove the same, and Tenant shall pay Landlord on demand for all costs of removal and storage thereof and for the rental value of the Premises for the period from the end of the Term through the end of the time reasonably required for such removal. Landlord shall also have the right to retain or dispose of all or any portion of such property if Tenant does not pay all such costs and retrieve the property within ten (10) days after notice from Landlord (in which event title to all such property described in Landlord notice shall be transferred to and vest in Landlord). Tenant waives all Claims against Landlord for any damage or loss to Tenant resulting from Landlord's removal, storage, retention, or disposition of any such property. Upon expiration or termination of this Lease or of Tenant's possession, whichever is earliest, Tenant shall surrender all keys to the Premises or any other part of the Building and shall deliver to Landlord all keys for or make known to Landlord the combination of locks on all safes, cabinets and vaults that may be located in the Premises. Tenant's obligations under this Section shall survive the expiration or termination of this Lease. 19.2 Holding Over. If Tenant (directly or through any Transferee or other successor-in-interest of Tenant) remains in possession of the Premises after the expiration or termination of this Lease, Tenant's continued possession shall be on the basis of a tenancy at the sufferance of Landlord. No act or omission by Landlord, other than its specific written consent, shall constitute permission for Tenant to continue in possession of the Premises, and if such consent is given or declared to have been given by a court judgement, Landlord may terminate Tenant's holdover tenancy at any time upon seven (7) days written notice. In such event, Tenant shall continue to comply with or perform all the terms and obligations of Tenant under this Lease, except that the monthly Base Rent during Tenant's holding over shall be twice the Base Rent payable in the last -28- <PAGE> 32 full month prior to the termination hereof. Acceptance by Landlord of rent after such termination shall not constitute a renewal or extension of this Lease; and nothing contained in this provision shall be deemed to waive Landlord's right of re-entry or any other right hereunder or at law. Tenant shall indemnify, defend and hold Landlord harmless from and against all Claims arising or resulting directly or indirectly from Tenant's failure to timely surrender the Premises, including (i) any rent payable by or any loss, cost, or damages claimed by any prospective tenant of the Premises, and (ii) Landlord's damages as a result of such prospective tenant rescinding or refusing to enter into the prospective lease of the Premises by reason of such failure to timely surrender the Premises. 20. ENCUMBRANCES. 20.1 Subordination. This Lease is expressly made subject and subordinate to any mortgage, deed of trust, ground lease, underlying lease or like encumbrance affecting any part of the Property or any interest of Landlord therein which is now existing or hereafter executed or recorded ("ENCUMBRANCE"); provided, however, that such subordination shall only be effective, as to future Encumbrances, if the holder of the Encumbrance agrees in writing that this Lease shall survive the termination of the Encumbrance by lapse of time, foreclosure or otherwise so long as Tenant is not in default under this Lease beyond any applicable notice and cure period. Provided the conditions of the preceding sentence are satisfied, Tenant shall execute and deliver to Landlord, within ten (10) Business Days after written request therefor by Landlord and in a form reasonably requested by Landlord, any additional documents evidencing the subordination of this Lease with respect to any such Encumbrance and the nondisturbance agreement of the holder of any such Encumbrance. If the interest of Landlord in the Property is transferred pursuant to or in lieu of proceedings for enforcement of any Encumbrance, Tenant shall immediately and automatically attorn to the new owner, and this Lease shall continue to full force and effect as a direct lease between the transferee and Tenant on the terms and conditions set forth in this Lease. Landlord agrees to use reasonable good faith efforts to obtain, at Tenant's cost and expense, within 60 days after execution of this Lease, a Subordination, Attornment and Non-Disturbance Agreement (the "SNDA") from the holder of any Encumbrance existing at the date of this Lease pursuant to the provisions contained above; provided, however, Landlord's failure to obtain an SNDA shall not affect the validity of this Lease. 20.2 Mortgagee Protection. Tenant agrees to give any holder of any Encumbrance covering any part of the Property ("MORTGAGEE"), by registered mail, a copy of any notice of default served upon Landlord, provided that prior to such notice Tenant has been notified in writing (by way of notice of assignment of rents and leases, or otherwise) of the address of such Mortgagee. If Landlord shall have failed to cure such default within thirty (30) days from the effective date of such notice of default, then the Mortgagee shall have an additional thirty (30) days within which to cure such default or if such default cannot be cured within that time, then such additional time as may be necessary to cure such default (including the time necessary to foreclose or otherwise terminate its Encumbrance, if necessary to effect such cure), and this Lease shall not be terminated so long as such remedies are being diligently pursued. -29- <PAGE> 33 21. ESTOPPEL CERTIFICATES AND FINANCIAL STATEMENTS. 21.1 Estoppel Certificates. Within ten (10) Business Days after written request therefor, Tenant shall execute and deliver to Landlord, in a form provided by or satisfactory to Landlord, a certificate stating that this Lease is in full force and effect, describing any amendments or modifications hereto, acknowledging that this Lease is subordinate or prior, as the case may be, to any Encumbrance and stating any other information Landlord may reasonably request, including the Term, the monthly Base Rent, the date to which Rent has been paid, the amount of any security deposit or prepaid rent, whether either party hereto is in default under the terms of the Lease, and whether Landlord has completed its construction obligations hereunder (if any). If Tenant fails timely to execute and deliver such certificate as provided above, then Landlord and the addressee of such certificate shall be entitled to rely upon the information contained in the certificate submitted to Tenant as true, correct and complete, and Tenant shall be estopped from later denying, contradicting or taking any position inconsistent with the information contained in such certificate. Any person or entity purchasing, acquiring an interest in or extending financing with respect to the Property shall be entitled to rely upon any such certificate. If Tenant fails to deliver such certificate within ten (10) Business Days after Landlord's second written request therefor, Tenant shall be liable to Landlord for any damages incurred by Landlord including any profits or other benefits from any financing of the Property or any interest therein which are lost or made unavailable as a result, directly or indirectly, of Tenant's failure or refusal to timely execute or deliver such estoppel certificate. 21.2 Financial Statements. Within ten (10) Business Days after written request therefor, but not more than once a year, Tenant shall deliver to Landlord a copy of the financial statements (including at least a year end balance sheet and a statement of profit and loss) of Tenant (and of each guarantor of Tenant's obligations under this Lease) for each of the two most recently completed years, prepared in accordance with generally accepted accounting principles (and, if such is Tenant's normal practice, audited by an independent certified public accountant), all then available subsequent interim statements, and such other financial information as may reasonably be requested by Landlord or required by any Mortgagee. Landlord shall not disclose details of such financial statements except (x) pursuant to court proceedings, and (y) to Landlord's (a) directors, (b) shareholders, (c) officers, (d) those employees of Landlord and of Landlord's agents who have a need to know, (e) accountants, (f) auditors, (g) lenders and/or Mortgagee, (h) purchasers, (i) potential lenders and/or Mortgagees and purchasers, and (j) attorneys. Landlord shall use all reasonable efforts to prevent such persons or employees of such entities from disclosing details of Tenant's financial statements. 22. NOTICES. Any notice, demand, request, consent or approval that either party desires or is required to give to the other party under this Lease shall be in writing and shall be served personally, delivered by messenger or courier service, or sent by U.S. certified mail, return receipt requested, postage prepaid, addressed to the other party at the party's address for notices set forth in the Basic Lease Information. Any notice required pursuant to any Laws may be incorporated into, given concurrently with or given separately from any notice required under this Lease. Notices shall be deemed to have been given and be effective on the earlier of (a) receipt (or refusal of delivery or receipt); or (b) one (1) day after acceptance by the independent service for delivery, if sent by independent messenger or courier service, or three (3) days after mailing if sent by mail in -30- <PAGE> 34 accordance with this Section. Either party may change its address for notices hereunder, effective fifteen (15) days after notice to the other party complying with this Section. If Tenant sublets the Premises, notices from Landlord shall be effective on the subtenant when given to Tenant pursuant to this Section. 23. ATTORNEYS' FEES. In the event of any dispute between Landlord and Tenant in any way related to this Lease, the non-prevailing party shall pay to the prevailing party all reasonable attorneys' fees and costs and expenses of any type incurred by the prevailing party in connection with any action or proceeding (including any appeal and the enforcement of any judgment or award), whether or not the dispute is litigated or prosecuted to final judgment. The "prevailing party" shall be determined based upon an assessment of which party's major arguments or positions taken in the action or proceeding could fairly be said to have prevailed (whether by compromise, settlement, abandonment by the other party of its claim or defense, final decision, after any appeals, or otherwise) over the other party's major arguments or positions on major disputed issues. 24. QUIET POSSESSION. Subject to Tenant's full and timely performance of all of Tenant's obligations under this Lease and subject to the terms of this Lease, including Section 20 - Encumbrances, Tenant shall have the quiet possession of the Premises throughout the Term as against any persons or entities lawfully claiming by, through or under Landlord. 25. SECURITY MEASURES. Tenant shall be responsible for all security measures for the Premises, such as the registration or search of all persons entering or leaving the Building, requiring identification for access to the Building, evacuation of the Building for cause, suspected cause, or for drill purposes, the issuance of magnetic pass cards or keys for Building or elevator access to prevent any threat of property loss or damage, bodily injury or business interruption. Landlord shall have no security responsibility for the Premises or the Project. Landlord, its agents and employees shall have no liability to Tenant or its Representatives or Visitors for the implementation or exercise of, or the failure to implement or exercise, any security measures for the Premises or the Project, or for any resulting disturbance of Tenant's use or enjoyment of the Premises. 26. FORCE MAJEURE. If either Landlord or Tenant is delayed, interrupted or prevented from performing any of its obligations under this Lease (other than, with respect to Tenant the payment of Base Rent, Additional Rent or any other charge payable by Tenant to Landlord under this Lease), including Landlord's obligations under the Construction Rider and such delay, interruption or prevention is due to fire, act of God, governmental act or failure to act, labor dispute, unavailability of materials or any cause outside the reasonable control of Landlord or Tenant, then the time for performance of the affected obligations of Landlord or Tenant, as the case may be, shall be extended for a period equivalent to the period of such delay, interruption or prevention. The inability to pay money shall in no event constitute force majeure. 27. RULES AND REGULATIONS. Tenant shall be bound by and shall comply with the rules and regulations attached to and made a part of this Lease as Exhibit C to the extent those rules and regulations are not in conflict with the terms of this Lease, as well as any reasonable rules and regulations hereafter adopted by Landlord for all tenants of the Building, upon notice to Tenant thereof (collectively, the "BUILDING RULES"). Landlord shall not be responsible to Tenant or to any -31- <PAGE> 35 other persons for any violation of, or failure to observe, the Building Rules by any other tenant or other person. 28. LANDLORD'S LIABILITY. The term "Landlord," as used in this Lease, shall mean only the owner or owners of the Building at the time in question. In the event of any conveyance of title to the Building, then from and after the date of such conveyance, upon such transferee's written recognition of this Lease, the transferor Landlord shall be relieved of all liability with respect to Landlord's obligations to be performed under this Lease after the date of such conveyance. Notwithstanding any other term or provision of this Lease, the liability of Landlord for its obligations under this Lease is limited solely to Landlord's interest in the Building as the same may from time to time be encumbered, and no personal liability shall at any time be asserted or enforceable against any other assets of Landlord or against Landlord's partners or members or its or their respective partners, shareholders, members, directors, officers or managers on account of any of Landlord's obligations or actions under this Lease. 29. CONSENTS AND APPROVALS. 29.1 Determination in Good Faith. Wherever the consent, approval, judgment or determination of Landlord is required or permitted under this Lease, Landlord may exercise its good faith business judgment in granting or withholding such consent or approval or in making such judgment or determination without reference to any extrinsic standard of reasonableness, unless the specific provision contained in this Lease providing for such consent, approval, judgment or determination specifies that Landlord's consent or approval is not to be unreasonably withheld, or that such judgment or determination is to be reasonable, or otherwise specifies the standards under which Landlord may withhold its consent. If it is determined that Landlord failed to give its consent where it was required to do so under this Lease, Tenant shall be entitled to injunctive relief but shall not be entitled to monetary damages or to terminate this Lease for such failure. 29.2 No Liability Imposed on Landlord. The review and/or approval by Landlord of any item or matter to be reviewed or approved by Landlord under the terms of this Lease or any Exhibits or Addenda hereto shall not impose upon Landlord any liability for the accuracy or sufficiency of any such item or matter or the quality or suitability of such item for its intended use. Any such review or approval is for the sole purpose of protecting Landlord's interest in the Property, and no third parties, including Tenant or the Representatives and Visitors of Tenant or any person or entity claiming by, through or under Tenant, shall have any rights as a consequence thereof. 30. BROKERS. Landlord shall pay the fee or commission of the broker or brokers identified in the Basic Lease Information (the "BROKER") in accordance with Landlord's separate written agreement with the Broker, if any. Tenant warrants and represents to Landlord that in the negotiating or making of this Lease neither Tenant nor anyone acting on Tenant's behalf has dealt with any broker or finder who might be entitled to a fee or commission for this Lease other than the Broker. Tenant shall indemnify and hold Landlord harmless from any claim or claims, including costs, expenses and attorney's fees incurred by Landlord asserted by any other broker or finder for a fee or commission based upon any dealings with or statements made by Tenant or Tenant's Representatives. Landlord shall indemnify and hold Tenant harmless from any claim or claims, -32- <PAGE> 36 including costs, expenses and attorney's fees incurred by Tenant asserted by any other broker or finder for a fee or commission based upon any dealings with or statements made by Landlord or Landlord's Representatives. 31. RELOCATION OF PREMISES. [Intentionally Deleted]. 32. ENTIRE AGREEMENT.

Tenant Improvements. Upon Tenant's written request made at any time within three (3) years after the Commencement Date of this Lease, and after completion of Final Construction Documents (as hereinafter defined), Landlord shall with reasonable diligence through Commercial Interior Contractors ("CIC") construct and install in the Premises the improvements and fixtures provided for in this Construction Rider ("TENANT IMPROVEMENTS"). Tenant recognizes and agrees that CIC is an affiliate of Landlord. Upon request by Landlord, Tenant shall designate in writing an individual authorized to act as Tenant's Representative with respect to all approvals, directions and authorizations pursuant to this Construction Rider. 1.1 Plans. The Tenant Improvements shall be constructed substantially as shown on the conceptual space plan for the Premises prepared by a space planner mutually agreeable to Landlord and Tenant, which space planner will be retained by Tenant (after Tenant's notice pursuant to the provisions of Section 1 above) as the space planner for the Premises ("SPACE PLANNER"), to prepare a space plan ("SPACE PLAN") reasonably acceptable to Landlord and Tenant. As soon as may be reasonably practicable after requested by Tenant, the Space Planner will prepare and deliver to Tenant detailed plans and specifications sufficient to permit the construction of the Tenant Improvements by Landlord's contractor ("CONSTRUCTION DOCUMENTS"), Landlord will provide Tenant with a cost estimate for the work shown in the Construction Documents. Tenant shall respond to the Construction Documents and cost estimate within three (3) Business Days after receipt thereof, specifying any changes or modifications Tenant desires in the Construction Documents. The Space Planner will then revise the Construction Documents and resubmit them to Tenant for its approval and Landlord will provide Tenant with a revised cost estimate. Tenant shall approve or disapprove the same within three (3) Business Days after receipt. The revised Construction Documents and cost estimate, as approved by Tenant and Landlord, are hereinafter referred to as the "FINAL CONSTRUCTION DOCUMENTS" and "FINAL COST ESTIMATE," respectively. Additional interior decorating services and advice on the furnishing and decoration of the Premises, such as the selection of fixtures, furnishings or design of mill work, shall be provided by Tenant at its expense, but shall be subject to the reasonable approval of Landlord. Exhibit B, Page 1 <PAGE> 40 1.2 Construction. Upon approval by Landlord and Tenant of the Final Construction Documents and the Final Cost Estimate, Landlord shall proceed with reasonable diligence to cause the Tenant Improvements to be Substantially Completed. CIC will construct the Tenant Improvements at competitive prices, with a fee not to exceed the market rate for other similar sized and type of construction contracts in the Redwood City, California area. CIC will competitively bid subcontracts, using at least three (3) subcontractors for each proposed subcontract. Tenant may add names to the subcontractor bid list prior to such subcontracts being put to bid, subject to the reasonable right of CIC and Landlord to review and approve subcontractors based on their qualifications, including quality of work, creditworthiness, and experience. Tenant agrees to cooperate with Landlord and CIC in planning and scheduling the construction of Tenant Improvements to allow CIC to proceed with construction of Tenant Improvements in an efficient manner, but Landlord will use, the cause CIC to use, reasonable efforts to not unreasonably disrupt Tenant's business operations during construction of Tenant Improvements. The Tenant Improvements shall be deemed to be "SUBSTANTIALLY COMPLETED" when they have been completed in accordance with the Final Construction Documents except for finishing details, minor omissions, decorations and mechanical adjustments of the type normally found on an architectural "punch list". (The definition of Substantially Completed shall also define the terms "SUBSTANTIAL COMPLETION" and "SUBSTANTIALLY COMPLETE.") Following Substantial Completion of the Tenant Improvements, Landlord and Tenant shall inspect the Premises and jointly prepare a "punch list" of agreed items of construction remaining to be completed. Landlord shall cause CIC to complete the items set forth in the punch list as soon as reasonably possible using commercially reasonable efforts. Tenant shall cooperate with and accommodate Landlord and CIC in completing the items on the punch list. 1.3 Cost of Tenant Improvements. Landlord shall contribute up to Two Hundred Three Thousand Nine Hundred Seventy-Five and 00/100 Dollars ($203,975.00) (the "ALLOWANCE"), based upon $5.00 per rentable square foot in the Premises toward the cost of the design (including preparation of space plans and Construction Documents), construction and installation of the Tenant Improvements. Tenant may use up to Fifty Thousand and 00/100 Dollars ($50,000.00) out of the Allowance for wiring and cabling in the Building. The balance, if any, of the cost of the Tenant Improvements ("ADDITIONAL COST"), including, but not limited to, usual markups for overhead, supervision and profit, shall be paid by Tenant. Tenant shall pay Landlord 50% of the Additional Cost based upon the Final Cost Estimate prior to the commencement of construction of the Tenant Improvements. The balance of the actual Additional Cost shall be paid to Landlord upon Substantial Completion of the Tenant Improvements, within twenty (20) days after receipt of Landlord's invoice therefor. Landlord will use reasonable care in preparing the cost estimates, but they are estimates only and do not limit Tenant's obligation to pay for the actual Additional Cost of the Tenant Improvements, whether or not it exceeds the estimated amounts. Exhibit B, Page 2 <PAGE> 41 1.4. Changes. If Tenant requests any change, addition or alteration in or to any Final Construction Documents ("CHANGES") Landlord shall cause the Space Planner to prepare additional Plans implementing such Change. Tenant shall pay the cost of preparing additional Plans within twenty (20) days after receipt of Landlord's invoice therefor. As soon as practicable after the completion of such additional Construction Documents, Landlord shall notify Tenant of the estimated cost of the Changes. Within three (3) Business Days after receipt of such cost estimate, Tenant shall notify Landlord in writing whether Tenant approves the Change. If Tenant approves the Change, Landlord shall proceed with the Change and Tenant shall be liable for any Additional Cost resulting from the Change. If Tenant fails to approve the Change within such three (3) Business Day period, construction of the Tenant Improvements shall proceed as provided in accordance with the original Construction Documents. 1.5. Delays. Tenant shall be responsible for, and shall pay to Landlord, any and all costs and expenses incurred by Landlord in connection with any delay in the commencement or completion of any Tenant Improvements and any increase in the cost of Tenant Improvements caused by (i) Tenant's failure to submit information to the Space Planner or approve any Space Plan, Construction Documents or cost estimates within the time periods required herein, (ii) any delays in obtaining any items or materials constituting part of the Tenant Improvements requested by Tenant, (iii) any Changes, or (iv) any other delay requested or caused by Tenant (collectively, "TENANT DELAYS"). 2.

Tenant agrees that Landlord shall not be liable in any way for any injury, loss or damage which may occur to any of Tenant's property placed upon or installed in the Premises prior to the Commencement Date, the same being at Tenant's sole risk, and Tenant shall be liable for all injury, loss or damage to persons or property arising as a result of such entry into the Premises by Tenant or its Representatives. 4.

Any extension of the Term shall be upon all the terms and conditions set forth in this Lease and all Exhibits thereto, except that; (i) Tenant shall have no further option to extend the Term of the Lease, other than as specifically set forth herein; (ii) Landlord shall not be obligated to contribute funds toward the cost of any remodeling, renovation, alteration or improvement work in the Premises; and (iii) Base Rent for any such Extension Period shall be the then Fair Market Base Rental (as defined below) for the Premises for the space and term involved, which shall be determined as set forth below. (a) "FAIR MARKET BASE RENTAL" shall mean the "fair market" Base Rent at the time or times in question for the applicable space, based on the prevailing rentals then being charged to tenants in the Project and tenants in other similar type buildings in the general vicinity of the Project of comparable size, location, quality and age as the Building for leases with terms equal to the Extension Period, taking into account the creditworthiness and financial strength of the tenant, the financial guaranties provided by the tenant (if any), the value of market concessions (including the value of construction, renovation, moving and other allowances or rent credits), the desirability, location in the building, size and quality of the space, tenant finish allowance and/or tenant improvements, included services, operating expenses and tax and expense stops or other escalation clauses, and brokerage commissions, for the space in the Building for which Fair Market Base Rental is being determined and for comparable space in the buildings which are being used for comparison. Fair Market Base Rental shall also reflect the then prevailing rental structure for comparable buildings in the general vicinity of the Property, so that if, for example, at the time Fair Market Base Rental is being determined the prevailing rental structure for comparable space and for comparable lease terms includes periodic rental adjustments or escalations, Fair Market Base Rental shall reflect such rental structure. (b) Landlord and Tenant shall endeavor to agree upon the Fair Market Base Rental. If they are unable to so agree within thirty (30) days after receipt by Landlord of Exhibit D, Page 4 <PAGE> 52 Tenant's notice of exercise of the Extension Option, Landlord and Tenant shall mutually select a licensed real estate broker who is active in the leasing of space similar to the Building in the general vicinity of the Project. Landlord shall submit Landlord's determination of Fair Market Base Rental and Tenant shall submit Tenant's determination of Fair Market Base Rental to such broker, at such time or times and in such manner as Landlord and Tenant shall agree (or as directed by the broker if Landlord and Tenant do not promptly agree). The broker shall select either Landlord's or Tenant's determination as the Fair Market Base Rental, and such determination shall be binding on Landlord and Tenant. If Tenant's determination is selected as the Fair Market Base Rental, then Landlord shall bear all of the broker's costs and fees. If Landlord's determination is selected as the Fair Market Base Rental, then Tenant shall bear all of the broker's cost and fees. (c) In the event the Fair Market Base Rental for any Extension Period has not been determined at such time as Tenant is obligated to pay Base Rent for such Extension Period, Tenant shall pay as Base Rent pending such determination, the Base Rent in effect for such space immediately prior to the Extension Period; provided, that upon the determination of the applicable Fair Market Base Rental, any shortage of Base Rent paid, together with interest at the rate specified in the Lease, shall be paid to Landlord by Tenant. (d) In no event shall the Base Rent during any Extension Period be less than the Base Rent in effect immediately prior to such Extension Period. (e) The term of this Lease, whether consisting of the Initial Term alone or the Initial Term as extended by any Extension Period (if any Extension Option is exercised), is referred to in this Lease as the "Term." 38. RIGHT OF FIRST OFFER - BUILDING 14. (a) Provided that Unwired Planet has not assigned this Lease or sublet any or all of the Premises other than to an Affiliate (it being intended that all rights pursuant to this provision are and shall be personal to the original Tenant under this Lease and its Affiliates and shall not be transferable or exercisable for the benefit of any Transferee), and provided Tenant is not in default beyond any applicable notice and cure period under this Lease at the time of the exercise of any such right or at any time thereafter until delivery of possession of the space to Tenant, and subject to any and all rights of other tenants in the Project with respect to such space (including renewal and extension rights and rights of first offer, first negotiation, first refusal or other expansion rights) existing as of the date of this Lease, Tenant shall have a one-time right of first offer to lease Building 14 ("Building 14"), containing approximately 40,897 rentable square feet, located at 900 Chesapeake, in the Project.

If building 14 becomes available, Landlord Exhibit D, Page 5 <PAGE> 53 shall offer to lease the entire Building 14 to Tenant at the same rent and on the same terms that Landlord intends to offer to other prospective tenants. Tenant shall have ten (10) days following receipt of Landlord's offer with respect to Building 14 within which to notify Landlord in writing of its intention to lease Building 14, and such notice, if given by Tenant, shall constitute an acceptance of Landlord's terms for the lease of such space. If Tenant exercises such right of first offer, the space to be leased by Tenant shall be leased on the same terms and conditions as are contained in this Lease except for the economic and other terms specifically set forth in Landlord's notice, and the parties shall execute an amendment to this Lease to include Building 14 in the Premises and otherwise to provide for the leasing of Building 14 on such terms. If Tenant fails so to exercise Tenant's right of first offer within such ten (10) day period, Landlord may thereafter lease Building 14 to other prospective tenants. (c) If Tenant does not lease Building 14 from Landlord when it is first offered to Tenant by Landlord, then this right of first offer shall terminate and Tenant shall have no further rights to lease any of Building 14. 39. RIGHT OF FIRST OFFER - BUILDING 19. (a) Provided that Unwired Planet has not assigned this Lease or sublet any or all of the Premises other than to an Affiliate (it being intended that all rights pursuant to this provision are and shall be personal to the original Tenant under this Lease and its Affiliates and shall not be transferable or exercisable for the benefit of any Transferee), and provided Tenant is not in default beyond any applicable notice and cure period under this Lease at the time of the exercise of any such right or at any time thereafter until delivery of possession of the space to Tenant, and subject to any and all rights of other tenants in the Project with respect to such space (including renewal and extension rights and rights of first offer, first negotiation, first refusal or other expansion rights) existing as of the date of this Lease, Tenant shall have a one-time right of first offer to lease Building 19 ("Building 19"), containing approximately 25,250 rentable square feet, located at 700 Chesapeake, in the Project. (b) Such right of first offer (i) may only be exercised with respect to vacant space or space which has been previously leased and as to which an existing tenant of Building 19 has elected not to extend its lease or re-lease such space and (ii) may only be exercised with respect to all of Building 19 being offered by Landlord. If Building 19 becomes available, Landlord shall offer to lease the entire Building 19 to Tenant at the same rent and on the same terms that Landlord intends to offer to other prospective tenants. Tenant shall have ten (10) days following receipt of Landlord's offer with respect to Building 19 within which to notify Landlord in writing of its intention to lease building 19, and such notice, if given by Tenant, shall constitute an acceptance of Landlord's terms for the lease of such space. If Tenant exercises such right of first offer, the space to be leased by Tenant shall be leased on the same terms and conditions as are contained in this Lease except for the economic and other terms specifically set forth in Landlord's notice, and the parties shall execute an amendment to this Lease to include Building 19 in the Premises and otherwise to provide for the leasing of Building 19 on such terms. If Tenant fails so to exercise Tenant's right of first offer within such ten (10) day period, Landlord may thereafter lease Building 19 to other prospective tenants. Exhibit D, Page 6 <PAGE> 54 (c) If Tenant does not lease Building 19 from Landlord when it is first offered to Tenant by Landlord, then this right of first offer shall terminate and Tenant shall have no further rights to lease any of Building 19. 40.
