                            STANDARD LEASE PROVISIONS

1.    Premises. Landlord hereby leases to Tenant and Tenant hereby leases from
Landlord, subject to all of the terms and conditions set forth herein, those
certain premises (the "Premises") described in the Basic Lease Information and
as outlined in red or as shown in the cross-hatched markings on the floor plan
attached hereto as Exhibit B. The parties agree that for all purposes hereunder
the Premises shall be stipulated to contain the number of square feet of
rentable area described in the Basic Lease Information. The Premises are located
in that certain office building (the "Building") whose street address is as
shown in the Basic Lease Information. The Building is located on that certain
land which is also improved with landscaping, parking facilities and other
improvements and appurtenances. Such land, together with all such improvements
and appurtenances and the Building, are all or part of a project which may
consist of more than one building and additional facilities, as described in the
Basic Lease Information (collectively referred to herein as the "Project").
However, Landlord reserves the right to make such changes, additions and/or
deletions to such land, the Building and the Project and/or the common areas and
parking or other facilities thereof as it shall determine from time to time.

2.    Term.

      (a) Unless earlier terminated in accordance with the provisions hereof,
the term of this Lease (the "Term") shall be as set forth in the Basic Lease
Information; provided, however, in the event the Term Commencement Date (defined
below) occurs on a date other than the first day of a calendar month, there
shall be added to the Term the partial month ("Partial Lease Month") from the
Term Commencement Date to (but not including) the first day of the calendar
month following the Term Commencement Date.

      (b) Subject to the provisions of this Paragraph 2, the Term shall commence
on the date (the "Term Commencement Date") which is the earlier of the date
Landlord delivers the Premises to Tenant or the date Tenant takes possession or
commences use of any portion of the Premises for any business purpose (including
moving in). If this Lease contemplates the construction of tenant improvements
in the Premises by Landlord, Landlord shall be deemed to have delivered the
Premises to Tenant on the date determined by Landlord's space planner to be the
date of substantial completion of the work to be performed by Landlord (as
described in the Improvement Agreement, if any, attached hereto as Exhibit C)
(the "Improvement Agreement"). Notwithstanding the foregoing, in the event that
Landlord is delayed in delivering the Premises by reason of any act or omission
of Tenant, the Term Commencement Date shall be (unless Tenant takes possession
or commences use of the Premises prior thereto) the date the Premises would have
been delivered by Landlord had such Tenant caused delay(s) not occurred. This
Lease shall be a binding contractual obligation effective upon execution hereof
by Landlord and Tenant, notwithstanding the later commencement of the Term.
Tenant acknowledges that Tenant has inspected and accepts the Premises in their
present condition, "as is", except for tenant improvements (if any) to be
constructed by Landlord in the Premises pursuant to the Improvement Agreement,
if any.

      (c) In the event the Term Commencement Date is delayed or otherwise does
not occur on the Scheduled Term Commencement Date specified in the Basic Lease
Information, this Lease shall not be void or voidable, the Term shall not be
extended (except as provided in Paragraph 2(a)), and Landlord shall not be
liable to Tenant for any loss or damage resulting therefrom; provided that
Tenant shall not be liable for any Rent (defined below) for any period prior to
the Term Commencement Date except as may otherwise be provided in this Lease.
Landlord may deliver to Tenant Landlord's standard form "Start-Up Letter" for
Tenant's acknowledgment and confirmation of the Term Commencement Date. Tenant
shall execute and deliver such Start-Up Letter to Landlord within five (5) days
after receipt thereof, but Tenant's failure or refusal to do so shall not negate
Tenant's acceptance of the Premises or affect determination of the Term
Commencement Date.

3.    Rent and Operating Expenses.

      3.1 Base Rent

            (a) Subject to the provisions of this Paragraph 3.1, Tenant agrees
to pay during the Term as Base Rent for the Premises the sums specified in the
Basic Lease Information (as increased from time to time as provided in the Basic
Lease Information or as may otherwise be provided in this Lease) ("Base Rent").

            (b) Base Rent shall increase as set forth in the Basic Lease
Information or as may otherwise be provided in this Lease.

            (c) Except as expressly provided to the contrary herein, Base Rent
shall be payable in equal consecutive monthly installments, in advance, without
deduction or offset, commencing on the Term Commencement Date and continuing on
the first day of each calendar month thereafter. However, the first full monthly
installment of Base Rent shall be payable upon Tenant's execution of this Lease.
If the Term Commencement Date is a day other than the first day of a calendar
month, then the Rent for the Partial Lease Month (the "Partial Lease Month
Rent") shall be prorated based on a month of 30 days. The Partial Lease Month
Rent shall be payable by Tenant on the first day of the calendar month next
succeeding the Term Commencement Date. Base Rent, all forms of additional rent
payable hereunder by Tenant and all other amounts, fees, payments or charges
payable hereunder by Tenant (collectively, "Additional Rent") shall (i) each
constitute rent payable hereunder (and shall sometimes collectively be referred
to herein as "Rent"), (ii) be payable to Landlord in lawful money of the United
States when due without any prior demand therefor, except as may be expressly
provided to the contrary herein, and (iii) be payable to Landlord at Landlord's
Remittance Address set forth in the Basic Lease Information or to such other
person or to such other place as Landlord may from time to time designate in
writing to Tenant. Any Rent or other amounts payable to Landlord by Tenant
hereunder for any fractional month shall be prorated based on a month of 30
days.

      3.2 Operating Expenses.

            (a) Subject to the provisions of this Lease, Tenant shall pay to
Landlord pursuant to this Paragraph 3.2 as Additional Rent an amount equal to
Tenant's Proportionate Share (defined below) of Operating Expenses (defined
below) allocable to each Expense Year (defined below). "Tenant's Proportionate
Share" is, subject to the provisions of this Paragraph 3.2, the percentage
number (representing the Premises' share of the Building and the Project) set
forth in the Basic Lease Information. An "Expense Year" is any calendar year any
portion of which falls within the Term.

            (b) "Operating Expenses" means all costs, expenses and obligations
incurred or payable by Landlord because of or in connection with the operation,
ownership, repair, replacement, restoration, management or maintenance of the
Project during or allocable to an Expense Year during the Term (other than
costs, expenses or obligations specifically attributable to Tenant or other
tenants of the Building or Project), all as determined by sound accounting
principles reasonably selected by Landlord and consistently applied, including
without limitation the following:


Short Form Office - Net Lease (CA)     -1-

                  (i) All property taxes, assessments, charges or impositions
and other similar governmental ad valorem or other charges levied on or
attributable to the Project (including personal and real property contained
therein) or its ownership, operation or transfer, and all taxes, charges,
assessments or similar impositions imposed in lieu or substitution (partially or
totally) of the same (collectively, "Taxes"). "Taxes" shall also include (A) all
taxes, assessments, levies, charges or impositions on any interest of Landlord
in the Project, the Premises or in this Lease, or on the occupancy or use of
space in the Project or the Premises; or on the gross or net rentals or income
from the Project, including, without limitation, any gross income tax, excise
tax, sales tax or gross receipts tax levied by any federal, state or local
governmental entity with respect to the receipt of Rent; or (B) any possessory
taxes charged or levied in lieu of real estate taxes; and

                  (ii) The cost of all utilities, supplies, equipment, tools,
materials, service contracts, janitorial services, waste and refuse disposal,
landscaping, and insurance (with the nature and extent of such insurance to be
carried by Landlord to be determined by Landlord in its sole and absolute
discretion); insurance deductibles; compensation and benefits of all persons who
perform services connected with the operation, management, maintenance or repair
of the Project; personal property taxes on and maintenance and repair of
equipment and other personal property; costs and fees for administration and
management of the Project (not to exceed five percent (5%) of Project revenues
in any Expense Year), whether by Landlord or by an independent contractor, and
other management office operational expenses; rental expenses for or a
reasonable allowance for depreciation of, personal property used in the
operation, management, maintenance or repair of the Project, license, permit and
inspection fees; and all inspections, activities, alterations, improvements or
other matters required by any governmental or quasi-governmental authority or by
Regulations (defined below), for any reason, including, without limitation,
capital improvements, whether capitalized or not; all capital additions,
repairs, replacements and improvements made to the Project or any portion
thereof by Landlord (A) of a personal property nature and related to the
operation, repair, maintenance or replacement of systems, facilities, equipment
or components of (or which service) the Project or portions thereof, (B)
required or provided in connection with any existing or future applicable
municipal, state, federal or other governmental statutes, rules, requirements,
regulations, laws, standards, orders or ordinances including, without
limitation, zoning ordinances and regulations, and covenants, easements and
restrictions of record (collectively, "Regulations"), (C) which are designed to
improve the operating efficiency of the Project, or (D) determined by Landlord
to be required to keep pace or be consistent with safety or health advances or
improvements (with such capital costs to be amortized over such periods as
Landlord shall determine with a return on capital at such rate as would have
been paid by Landlord on funds borrowed for the purpose of constructing such
capital items); common area repair, resurfacing, replacement, operation and
maintenance; security systems or services, if any, deemed appropriate by
Landlord (but without obligation to provide the same); and any other cost or
expense incurred or payable by Landlord in connection with the operation,
ownership, repair, replacement, restoration, management or maintenance of the
Project.

            (c) Variable items of Operating Expenses (e.g., expenses that are
affected by variations in occupancy levels) for each Expense Year during which
actual occupancy of the Project is less than ninety-five percent (95%) of the
rentable area of the Project shall be appropriately adjusted, in accordance with
sound accounting principles, to reflect ninety-five percent (95%) occupancy of
the existing rentable area of the Project during such period.

            (d) Prior to or shortly following the commencement of (and from time
to time during) each calendar year of the Term following the Term Commencement
Date, Landlord shall have the right to give to Tenant a written estimate of
Tenant's Proportionate Share of the projected Operating Expenses for the Project
for such year. Commencing with the first day of the calendar month following the
month in which such estimate was delivered to Tenant, Tenant shall pay such
estimated amount (less amounts, if any, previously paid toward such year) to
Landlord in equal monthly installments over the remainder of such calendar year,
in advance on the first day of each month during such year (or remaining months,
if less than all of the year remains). Subject to the provisions of this Lease,
Landlord shall endeavor to furnish to Tenant within a reasonable period after
the end of each Expense Year, a statement (a "Reconciliation Statement")
indicating in reasonable detail Tenant's Proportionate Share of the Operating
Expenses allocable to such Expense Year and the parties shall, within thirty
(30) days thereafter, make any payment or allowance necessary to adjust Tenant's
estimated payments to Tenant's actual share of Operating Expenses as indicated
by such annual Reconciliation Statement.

            (e) Tenant shall pay ten (10) days before delinquency all taxes and
assessments levied against any personal property or trade fixtures of Tenant in
or about the Premises. If any such taxes or assessments are levied against
Landlord or Landlord's property or if the assessed value of the Project is
increased by the inclusion therein of a value placed upon such personal property
or trade fixtures, Tenant shall, within ten (10) days of demand, reimburse
Landlord for the taxes and assessments so levied against Landlord, or any such
taxes, levies and assessments resulting from such increase in assessed value.

            (f) Any delay or failure of Landlord in (i) delivering any estimate
or statement described in this Paragraph 3.2, or (ii) computing or billing
Tenant's Proportionate Share of Operating Expenses shall not (A) constitute a
waiver of its right to subsequently deliver such estimate or statement or
require any increase in Rent contemplated by this Paragraph 3.2, or (B) in any
way waive or impair the continuing obligations of Tenant under this Paragraph
3.2. Provided that Tenant is not then in default under this Lease, subject to
compliance with Landlord's standard procedures for the same, Tenant shall have
the right, upon the condition that Tenant shall first pay to Landlord the amount
in dispute, to have independent certified public accountants of national
standing (who are not compensated on a contingency basis) of Tenant's selection
(and subject to Landlord's reasonable approval) review Landlord's Operating
Expense books and records relating to the Expense Year subject to a particular
Reconciliation Statement during the sixty-day period following delivery to
Tenant of the Reconciliation Statement for such Expense Year. If such review
discloses a liability for a refund in excess of ten percent (10%) of Tenant's
Proportionate Share of Operating Expenses previously reported, the cost of such
review shall be borne by Landlord; otherwise such cost shall be borne by Tenant.
Tenant waives the right to dispute or contest, and shall have no right to
dispute or contest, any matter relating to the calculation of Operating Expenses
or other forms of Rent under this Paragraph 3.2 with respect to each Expense
Year for which a Reconciliation Statement is given to Tenant if no claim or
dispute with respect thereto is asserted by Tenant in writing to Landlord within
sixty (60) days of delivery to Tenant of the original or most recent
Reconciliation Statement with respect thereto.

            (g) This shall be a triple net Lease and Base Rent shall be paid to
Landlord absolutely net of all costs and expenses, except as specifically
provided to the contrary in this Lease. The provisions for payment of Operating
Expenses and the Operating Expense adjustment are intended to pass on to Tenant
and reimburse Landlord for all costs and expenses of the nature described in
Paragraph 3.2(b) incurred in connection with the operation, ownership, repair,
replacement, restoration, management or maintenance of the Building and/or
Project.

4.    Delinquent Payment; Handling Charges. In the event Tenant is more than
three (3) days late in paying any amount of Rent or any other payment due under
this Lease, Tenant shall pay Landlord, within ten (10) days of Landlord's
written demand therefor, a late charge equal to five percent (5%) of the
delinquent amount, or $150.00, whichever amount is greater. In addition, any
amount due from Tenant to Landlord hereunder which is not paid within ten (10)
days of the date due shall bear interest at an annual rate (the "Default Rate")
equal to twelve percent (12%).

Version 10.1
<PAGE>

5.    Security Deposit. Contemporaneously with the execution of this Lease,
Tenant shall pay to Landlord the amount of Security Deposit (the "Security
Deposit") specified in the Basic Lease Information, which shall be held by
Landlord to secure Tenant's performance of its obligations under this Lease.
Landlord is hereby granted a security interest in the Security Deposit in
accordance with applicable provisions of the California Commercial Code. The
Security Deposit is not an advance payment of Rent or a measure or limit of
Landlord's damages upon a default by Tenant or an Event of Default (defined
below). If Tenant defaults with respect to any provision of this Lease, Landlord
may, but shall not be required to, use, apply or retain all or any part of the
Security Deposit (a) for the payment of any Rent or any other sum in default,
(b) for the payment of any other amount which Landlord may spend or become
obligated to spend by reason of such default by Tenant, and (c) to compensate
Landlord for any other loss or damage which Landlord may suffer by reason of
such default by Tenant. If any portion of the Security Deposit is so used or
applied, Tenant shall, within ten (10) days after demand therefor by Landlord,
deposit with Landlord cash in an amount sufficient to restore the Security
Deposit to the amount required to be maintained by Tenant hereunder. Within a
reasonable period following expiration or the sooner termination of this Lease
provided that Tenant has performed all of its obligations hereunder, Landlord
shall return to Tenant the remaining portion of the Security Deposit. The
Security Deposit may be commingled by Landlord with Landlord's other funds, and
no interest shall be paid thereon. If Landlord transfers its interest in the
Premises, then Landlord may assign the Security Deposit to the transferee and
thereafter Landlord shall have no further liability or obligation for the return
of the Security Deposit. Tenant hereby waives the provisions of Section 1950.7
of the California Civil Code, and all other provisions of any Regulations, now
or hereinafter in force, which restricts the amount or types of claim that a
landlord may make upon a security deposit or imposes upon a landlord (or its
successors) any obligation with respect to the handling or return of security
deposits.

6.    Landlord's Obligations.

      6.1 Services. Subject to the provisions of this Lease, Landlord shall
furnish to Tenant during the Term (a) city or utility company water at those
points of supply provided for general use of the tenants of the Building; (b)
subject to mandatory and voluntary Regulations, heating and air conditioning
during ordinary business hours of generally recognized business days designated
by Landlord (which in any event shall not include Saturdays, Sundays or legal
holidays) ("Business Hours") for the Building at such temperatures and in such
amounts as Landlord reasonably determines is appropriate for normal comfort for
normal office use in the Premises; (c) janitorial services to the Premises on
weekdays, other than on legal holidays, for Building-standard installations; (d)
nonexelusive passenger elevator service; and (e) adequate electrical current
during such Business Hours for equipment that does not require more than 110
volts and whose electrical energy consumption does not exceed normal office
usage in a premises of the size of the Premises, as determined by Landlord. If
Tenant desires any of the services specified in this Paragraph 6.1 at any time
other than during Business Hours, then subject to such nondiscriminatory
conditions and standards as Landlord shall apply to the same, upon the written
request of Tenant, such services shall be supplied to Tenant in accordance with
Landlord's customary procedures for the Building, including such advance request
deadlines as Landlord shall require from time to time, and Tenant shall pay to
Landlord Landlord's then customary charge for such services within ten (10) days
after Landlord has delivered to Tenant an invoice therefor. Landlord reserves
the right to change the supplier or provider of any such service from time to
time. Tenant shall not have the right to obtain any such service for the
Premises directly from a supplier or provider of such service except as provided
in Paragraph 6.4 below.

      6.2 Excess Utility Use. Landlord shall not be required to furnish
electrical current for, and Tenant shall not install or use, without Landlord's
prior written consent, any equipment (a) that requires more than 110 volts, (b)
whose operation is in excess of, or inconsistent with, the capacity of the
Building (or existing feeders and risers to, or wiring in, the Premises) or (c)
whose electrical energy consumption exceeds normal office usage of up to three
(3) watts of connected load per usable square foot ("Standard Usage"). Subject
to the provisions of this Paragraph 6.2, if Tenant's consumption of electricity
exceeds the electricity to be provided by Landlord above or Standard Usage
(which shall be determined by separate metering to be installed at Tenant's
expense or by such other method as Landlord shall reasonably select), Tenant
shall pay to Landlord Landlord's then customary charge for such excess
consumption within ten (10) days after Landlord has delivered to Tenant an
invoice therefor.

      6.3 Restoration of Services. Following receipt of Tenant's request to do
so, Landlord shall use good faith efforts to restore any service specifically to
be provided under Paragraph 6.1 that becomes unavailable and which is in
Landlord's reasonable control to restore; provided, however, that in no case
shall the unavailability of such services or any other service (or any
diminution in the quality or quantity thereof) or any interference in Tenant's
business operations within the Premises render Landlord liable to Tenant or any
person using or occupying the Premises under or through Tenant (including,
without limitation, any contractor, employee, agent, invitee or visitor of
Tenant) (each, a "Tenant Party") for any damages of any nature whatsoever caused
thereby, constitute a constructive eviction of Tenant, constitute a breach of
any implied warranty by Landlord, or entitle Tenant to any abatement of Tenant's
rental obligations hereunder.

      6.4 Telecommunications Services. Tenant may contract separately with
providers of telecommunications or cellular products, systems or services for
the Premises. Even though such products, systems or services may be installed or
provided by such providers in the Building, in consideration for Landlord's
permitting such providers to provide such services to Tenant, Tenant agrees that
Landlord and the Landlord Indemnitees (defined below) shall in no event be
liable to Tenant or any Tenant Party for any damages of any nature whatsoever
arising out of or relating to the products, systems or services provided by such
providers (or any failure, interruption, defect in or loss of the same) or any
acts or omissions of such providers in connection with the same or any
interference in Tenant's business caused thereby. Tenant waives and releases all
rights and remedies against Landlord and the Landlord Indemnitees that are
inconsistent with the foregoing.

7.    Improvements, Alterations, Repairs and Maintenance.

      7.1 Improvements; Alterations. Any alterations, additions, deletions,
modifications or utility installations in, of or to the improvements contained
within the Premises (collectively, "Alterations") shall be installed at Tenant's
expense and only in accordance with detailed plans and specifications,
construction methods, and all appropriate permits and licenses, all of which
have been previously submitted to and approved in writing by Landlord, and by a
professionally qualified and licensed contractor and subcontractors approved by
Landlord. No Alterations in or to the Premises may be made without (a)
Landlord's prior written consent and (b) compliance with such nondiscriminatory
requirements and construction regulations concerning such Alterations as
Landlord may impose from time to time. Landlord will not be deemed to
unreasonably withhold its consent to any Alteration that violates Regulations,
may affect or be incompatible with the Building's structure or its HVAC,
plumbing, telecommunications, elevator, life-safety, electrical, mechanical or
other basic systems, or the appearance of the interior common areas or exterior
of the Project, or which may interfere with the use or occupancy of any other
portion of the Project. All Alterations made in or upon the Premises shall, (i)
at Landlord's option, either be removed by Tenant prior to the end of the Term
(and Tenant shall restore the portion of the Premises affected to its condition
existing immediately prior to such Alteration), or shall remain on the Premises
at the end of the Term, (ii) be constructed, maintained, insured and used by
Tenant, at its risk and expense, in a first-class, good and workmanlike manner,
and in accordance with all Regulations, and (iii) shall be subject to payment of
Landlord's standard alterations supervision fee. If any Alteration made or
initiated by Tenant or the removal thereof shall cause, trigger or result in any
portion of the Project outside of the Premises, any portion of the Building's
shell and core improvements (including


Short Form Office - Net Lease (CA)     -3-
Version 10.1
<PAGE>

restrooms, if any) within the Premises, or any Building system inside or outside
of the Premises being required by any governmental authority to be altered,
improved or removed, or may otherwise potentially affect such portions of the
Project or any other tenants of the Project, Landlord shall have the option (but
not the obligation) of performing the same at Tenant's expense, in which case
Tenant shall pay to Landlord (within ten (10) days of Landlord's written demand)
in advance Landlord's reasonable estimate of the cost of such work, and any
actual costs of such work in excess of Landlord's estimate, plus an
administrative charge of fifteen percent (l5%) thereof. At least ten (10) days
before beginning construction of any Alteration, Tenant shall give Landlord
written notice of the expected commencement date of that construction to permit
Landlord to post and record a notice of non-responsibility. Upon substantial
completion of construction, if the law so provides, Tenant shall cause a timely
notice of completion to be recorded in the office of the recorder of the county
in which the Building is located.

      7.2 Repairs and Maintenance. Tenant shall maintain at all times during the
Term the Premises and all portions and components of the improvements and
systems contained therein in a first-class, good, clean, safe, and operable
condition, and shall not permit or allow to remain any waste or damage to any
portion of the Premises. Tenant shall repair or replace, as needed, subject to
Landlord's direction and supervision, any damage to the Building or the Project
caused by Tenant or any Tenant Party. If any such damage occurs outside of the
Premises or relates to any Building system, or if Tenant fails to perform
Tenant's obligations under this Paragraph 7.2 or under any other paragraph of
this Lease within ten (10) days' after written notice from Landlord (except in
the case of an emergency, in which case no notice shall be required), then
Landlord may elect to perform such obligations and repair such damage itself at
Tenant's expense. The cost of all repair or replacement work performed by
Landlord under this Paragraph 7.2, plus an administrative charge of fifteen
percent (15%) of such cost, shall be paid by Tenant to Landlord within ten (10)
days of receipt of Landlord's invoice therefor as Additional Rent. Tenant hereby
waives all common law and statutory rights or provisions inconsistent herewith,
whether now or hereinafter in effect (including, without limitation, Sections
1941, 1941.1, and 1941.2 of the California Civil Code, as amended from time to
time). Landlord shall use reasonable efforts to maintain the common areas of the
Project at all times during the Term with the cost thereof constituting an
Operating Expense under Paragraph 3.2.

      7.3 Mechanic's Liens. Tenant shall not cause, suffer or permit any
mechanic's or materialman's lien, claim, or stop notice to be filed or asserted
against the Premises, the Building or any funds of Landlord for any work
performed, materials furnished, or obligation incurred by or at the request of
Tenant or any Tenant Party. If any such lien, claim or notice is filed or
asserted, then Tenant shall, within ten (10) days after Landlord has delivered
notice of the same to Tenant, either (a) pay and satisfy in full the amount of
(and eliminate of record) the lien, claim or notice or (b) diligently contest
the same and deliver to Landlord a bond or other security therefor in substance
and amount (and issued by an issuer) satisfactory to Landlord.

8.    Use. Tenant shall continuously occupy and use the Premises only for
general office use or uses incidental thereto, all of which shall be consistent
with the standards of a first class office project (the "Permitted Use") and
shall comply, at Tenant's expense, with all Regulations relating to the use,
condition, alteration, improvement, access to, and occupancy of the Premises,
including without limitation, Regulations relating to Hazardous Materials
(defined below). Should any Regulation now or hereafter be imposed on Tenant or
Landlord by any governmental body relating to the use or occupancy of the
Premises or the Project common areas by Tenant or any Tenant Party or concerning
occupational, health or safety standards for employers, employees, or tenants,
then Tenant agrees, at its sole cost and expense, to comply promptly with such
Regulations if such Regulations relate to anything within the Premises or if
compliance with such Regulations is within the control of Tenant and applies to
an area outside of the Premises. Tenant shall conduct its business and shall
cause each Tenant Party to act in such a manner as to (a) not release or permit
the release of any Hazardous Material in, under, on or about the Project in
violation of any Regulations, (b) use or store any Hazardous Materials (other
than incidental amounts of cleaning and office supplies) in or about the
Premises or (c) not create or permit any nuisance or unreasonable interference
with or disturbance of other tenants of the Project or Landlord in its
management of the Project or (d) not create any occupancy density in the
Premises or parking density with respect to Tenant and any Tenant Party at the
Project greater than those specified in the Basic Lease Information. "Hazardous
Material" means any hazardous, explosive, radioactive or toxic substance,
material or waste which is or becomes regulated by any local, state or federal
governmental authority or agency, including, without limitation, any material or
substance which is (i) defined or listed as a "hazardous waste," "extremely
hazardous waste," "restricted hazardous waste," "hazardous substance,"
"hazardous material," "pollutant" or contaminant" under any Regulation, (ii) a
flammable explosive, (iii) a radioactive material, (iv) a polychlorinated
biphenyl, (v) asbestos or asbestos containing material, or (vi) a carcinogen.

9.    Assignment and Subletting.

      9.1 Transfers; Consent. Tenant shall not, without the prior written
consent of Landlord, (a) assign, transfer, mortgage, hypothecate, or encumber
this Lease or any estate or interest herein, whether directly, indirectly or by
operation of law, (b) permit any other entity to become a Tenant hereunder by
merger, consolidation, or other reorganization, (c) if Tenant is a corporation,
partnership, limited liability company, limited liability partnership, trust,
association or other business entity (other than a corporation whose stock is
publicly traded), permit, directly or indirectly, the transfer of any ownership
interest in Tenant so as to result in (i) a change in the current control of
Tenant, (ii) a transfer of twenty-five percent (25%) or more in the aggregate in
any twelve (12) month period in the beneficial ownership of such entity or (iii)
a transfer of all or substantially all of the assets of Tenant, (d) sublet any
portion of the Premises, or (e) grant any license, concession, or other right of
occupancy of or with respect to any portion of the Premises, or (f) permit the
use of the Premises by any party other than Tenant or a Tenant Party (each of
the events listed in this Paragraph 9.1 being referred to herein as a
"Transfer"). If Tenant requests Landlord's consent to any Transfer, then at
least twenty (20) business days prior to the effective date of the proposed
Transfer, Tenant shall provide Landlord with a written description of all terms
and conditions of the proposed Transfer and all consideration therefor
(including a calculation of the Transfer Profits described below), copies of the
proposed documentation, and the following information relating to the proposed
transferee: name and address; information reasonably satisfactory to Landlord
concerning the proposed transferee's business and business history; its proposed
use of the Premises; banking, financial, and other credit information; and
general references sufficient to enable Landlord to determine the proposed
transferee's creditworthiness and character. Landlord shall not unreasonably
withhold its consent to any assignment or subletting of the Premises, provided
that the parties agree that it shall be reasonable for Landlord to withhold any
such consent if, without limitation, Landlord determines in good faith that (A)
the proposed transferee is not of a reasonable financial standing or is not
creditworthy, (B) the proposed transferee is a governmental agency, (C) the
proposed transferee, or any affiliate thereof, is then an occupant in the
Project or has engaged in discussions with Landlord concerning a lease of direct
space in the Project, (D) the proposed Transfer would result in a breach of any
obligation of Landlord or permit any other tenant in the Project to terminate or
modify its lease, (E) there is then in effect an uncured Event of Default, (F)
the Transfer would increase the occupancy density or parking density of the
Project or any portion thereof, (G) the Transfer would result in an undesirable
tenant mix for the Project, as determined in good faith by Landlord, (H) the
proposed transferee does not enjoy a good reputation, as a business or as a
tenant; or (I) any guarantor of the Lease does not consent to such Transfer in a
form satisfactory to Landlord. Any Transfer made without Landlord's consent
shall be void and, at Landlord's election, shall constitute an Event of Default
by Tenant. Tenant shall also, within ten (10) days of written demand therefor,
pay to Landlord $500 as a review fee for each Transfer request, and reimburse
Landlord for its reasonable attorneys' fees and all other costs incurred in
connection with considering any request for consent to a proposed Transfer. If
Landlord consents to a proposed Transfer, then the proposed transferee shall
deliver to Landlord Landlord's standard form transfer


Short Form Office - Net Lease (CA)     -4-
Version 10.1
<PAGE>

consent and agreement whereby the proposed transferee expressly assumes the
Tenant's obligations hereunder. Landlord's consent to a Transfer shall not
release Tenant from its obligations under this Lease (or any guarantor of this
Lease of its obligations with respect thereto), but rather Tenant and its
transferee shall be jointly and severally liable for all obligations under this
Lease allocable to the space subject to such Transfer. Landlord's consent to any
Transfer shall not waive Landlord's rights as to any subsequent Transfers. In
the event of any claim by Tenant that Landlord has breached its obligations
under this Paragraph 9.1, Tenant's remedies shall be limited to recovery of its
out-of-pocket damages and injunctive relief.

      9.2 Cancellation and Recapture. Notwithstanding Paragraph 9.1, Landlord
may (but shall not be obligated to), within ten (10) business days after
submission of Tenant's written request for Landlord's consent to an assignment
or subletting, cancel this Lease as to the portion of the Premises proposed to
be sublet or subject to an assignment of this Lease ("Transfer Space") as of the
date such proposed Transfer is proposed to be effective and, thereafter,
Landlord may lease such portion of the Premises to the prospective transferee
(or to any other person or entity or not at all) without liability to Tenant. If
Landlord shall not cancel this Lease within such ten (10) business day period
and notwithstanding any Landlord consent to the proposed Transfer, Tenant shall
pay to Landlord, immediately upon receipt thereof, the entire excess ("Transfer
Profits") of all compensation and other consideration paid to or for the benefit
of Tenant (or any affiliate thereof) for the Transfer in excess of Base Rent and
Additional Rent payable by Tenant hereunder (with respect to the Transfer Space)
during the remainder of the Term (after straight-line amortization of any
reasonable brokerage commissions and tenant improvement costs paid by Tenant in
connection with the Transfer over the term of the Transfer). In any assignment
or subletting undertaken by Tenant, Tenant shall diligently seek to obtain the
maximum rental amount available in the marketplace for comparable space
available for primary leasing.

10.   Insurance, Waivers, Subrogation and Indemnity.

      10.1 Insurance. Tenant shall maintain throughout the Term each of the
insurance policies described on Exhibit D attached hereto and shall otherwise
comply with the obligations and requirements provided on Exhibit D.

      10.2 Waiver of Subrogation. Landlord and Tenant each waives any claim,
loss or cost it might have against the other for any injury to or death of any
person or persons, or damage to or theft, destruction, loss, or loss of use of
any property (a "Loss"), to the extent the same is insured against (or is
required to be insured against under the terms hereof) under any "all risk"
property damage insurance policy covering the Building, the Premises, Landlord's
or Tenant's fixtures, personal property, leasehold improvements, or business,
regardless of whether the negligence of the other party caused such Loss.

      10.3 Indemnity. Subject to Paragraph 10.2, Tenant shall indemnify, defend
and hold Landlord, Spieker Properties, Inc., and each of their respective
directors, shareholders, partners, lenders, members, managers, contractors,
affiliates and employees (collectively, "Landlord Indemnitees") from and against
all claims, demands, proceedings, losses, obligations, liabilities, causes of
action, suits, judgments, damages, penalties, costs and expenses (including,
without limitation, reasonable attorneys' fees and court costs) arising from or
asserted in connection with the use or occupancy of the Premises by Tenant or
any Tenant Party, including, without limitation, by reason of any release of any
Hazardous Materials by Tenant or any Tenant Party in, under, on, or about the
Project, or any negligence or misconduct of Tenant or of any Tenant Party in or
about the Premises, or Tenant's breach of any of its covenants under this Lease,
except in each case to the extent arising from the gross negligence or willful
misconduct of Landlord or any Landlord Indemnitee. Except to the extent
expressly provided in this Lease, Tenant hereby waives all claims against and
releases Landlord and each Landlord Indemnitee for any injury to or death of
persons, damage to property or business loss in any manner related to (i)
Tenant's use and occupancy of the Premises, (ii) acts of God, (iii) acts of
third parties, or (iv) any matter outside of the reasonable control of Landlord.
This Paragraph 10.3 shall survive termination or expiration of this Lease.

11.   Subordination; Attornment.

      11.1 Subordination. This Lease is subject and subordinate to all present
and future ground or master leases of the Project and to the lien of all
mortgages or deeds of trust (collectively, "Security Instruments") now or
hereafter encumbering the Project, if any, and to all renewals, extensions,
modifications, consolidations and replacements thereof, and to all advances made
or hereafter to be made upon the security of any such Security Instruments,
unless the holders of any such mortgages or deeds of trust, or the lessors under
such ground or master leases (such holders and lessors are sometimes
collectively referred to herein as "Holders") require in writing that this Lease
be superior thereto. Notwithstanding any provision of this Paragraph 11 to the
contrary, any Holder of any Security Instrument may at any time subordinate the
lien of its Security Instrument to this Lease without obtaining Tenant's consent
by giving Tenant written notice of such subordination, in which event this Lease
shall be deemed to be senior to the Security Instrument in question. Tenant
shall, within fifteen (15) days of request to do so by Landlord, execute,
acknowledge and deliver to Landlord such further instruments or assurances as
Landlord may deem necessary or appropriate to evidence or confirm the
subordination or superiority of this Lease to any such Security Instrument;
provided, however, that at the request of Tenant made within five (5) days of
any such Landlord request, Landlord shall use commercially reasonable efforts to
obtain for the benefit of Tenant such Holder's standard nondisturbance
agreement. Tenant hereby irrevocably authorizes Landlord to execute and deliver
in the name of Tenant any such instrument or instruments if Tenant fails to do
so within said fifteen (15) day period.

      11.2 Attornment. Tenant covenants and agrees that in the event that any
proceedings are brought for the foreclosure of any mortgage or deed of trust, or
if any ground or master lease is terminated, it shall attorn, without any
deductions or set-offs whatsoever, to the purchaser upon any such foreclosure
sale, or to the lessor of such ground or master lease, as the case may be, if so
requested to do so by such purchaser or lessor, and to recognize such purchaser
or lessor as "Landlord" under this Lease. If requested, Tenant shall enter into
a new lease with that successor on the same terms and conditions as are
contained in this Lease (for the unexpired portion of the Term then remaining).

12.   Rules and Regulations. Tenant shall comply, and shall cause each Tenant
Party to comply, with the Rules and Regulations of the Building which are
attached hereto as Exhibit A, and all such nondiscriminatory modifications,
additions, deletions and amendments thereto as Landlord shall adopt in good
faith from time to time.

13.   Condemnation. If the entire Project or Premises are taken by right of
eminent domain or conveyed by Landlord in lieu thereof (a "Taking"), this Lease
shall terminate as of the date of the Taking. If any part of the Project becomes
subject to a Taking and such Taking will prevent Tenant from conducting its
business in the Premises in a manner reasonably comparable to that conducted
immediately before such Taking for a period of more than one hundred eighty
(180) days, then Tenant may terminate this Lease as of the date of such Taking
by giving written notice to Landlord within thirty (30) days after the Taking,
and all Rent paid or payable hereunder shall be apportioned between Landlord and
Tenant as of the date of such Taking. If any material portion, but less than
all, of the Project, Building or the Premises becomes subject to a Taking, or if
Landlord is required to pay any of the proceeds received for a Taking to any
Holder of any Security Instrument, then Landlord may terminate this Lease by
delivering written notice thereof to Tenant within thirty (30) days after such
Taking, and all Rent paid or payable hereunder shall be apportioned


Short Form Office - Net Lease (CA)     -5-
Version 10.1
<PAGE>

between Landlord and Tenant as of the date of such Taking. If this Lease is not
so terminated, then Base Rent thereafter payable hereunder shall be abated for
the duration of the Taking in proportion to that portion of the Premises
rendered untenantable by such Taking. If any Taking occurs, then Landlord shall
receive the entire award or other compensation for the land on which the Project
is situated, the Project, and other improvements taken, and Tenant may
separately pursue a claim (to the extent it will not reduce Landlord's award)
against the condemnor for the value of Tenant's personal property which Tenant
is entitled to remove under this Lease and moving and relocation costs. Landlord
and Tenant agree that the provisions of this Paragraph 13 and the remaining
provisions of this Lease shall exclusively govern the rights and obligations of
the parties with respect to any Taking of any portion of the Premises, the
Building, the Project or the land on which the Building is located, and Landlord
and Tenant hereby waive and release each and all of their respective common law
and statutory rights inconsistent herewith, whether now or hereinafter in effect
(including, without limitation, Section l265.l30 of the California Code of Civil
Procedure, as amended from time to time).

14.   Fire or Other Casualty.

      14.1 Repair Estimate; Right to Terminate. If all or any portion of the
Premises, the Building or the Project is damaged by fire or other casualty (a
"Casualty"), Landlord shall, within ninety (90) days after Landlord's discovery
of such damage, deliver to Tenant its good faith estimate (the "Damage Notice")
of the time period following such notice needed to repair the damage caused by
such Casualty. Landlord may elect to terminate this Lease in any case where (a)
any portion of the Premises or any material portion of the Project are damaged
and (b) either (i) Landlord estimates in good faith that the repair and
restoration of such damage under Paragraph 14.2 ("Restoration") cannot
reasonably be completed (without the payment of overtime) within two hundred
(200) days of Landlord's actual discovery of such damage, (ii) the Holder of any
Security Instrument requires the application of any insurance proceeds with
respect to such Casualty to be applied to the outstanding balance of the
obligation secured by such Security Instrument, (iii) the cost of such
Restoration is not fully covered by insurance proceeds available to Landlord
and/or payments received by Landlord from tenants, or (iv) Tenant shall be
entitled to an abatement of rent under this Paragraph 14 for any period of time
in excess of thirty-three percent (33%) of the remainder of the Term, Such right
of termination shall be exercisable by Landlord by delivery of written notice to
Tenant at any time following the Casualty until forty-five (45) days following
the later of (A) delivery of the Damage Notice or (B) Landlord's discovery or
determination of any of the events described in clauses (i) through (iv) of the
preceding sentence, and shall be effective upon delivery of such notice of
termination (or if Tenant has not vacated the Premises, upon the expiration of
thirty (30) days thereafter).

      14.2 Repair Obligation; Abatement of Rent. Subject to the provisions of
Paragraph 14.1, Landlord shall, within a reasonable time after the discovery by
Landlord of any damage resulting from a Casualty, begin to repair the damage to
the Building and the Premises resulting from such Casualty and shall proceed
with reasonable diligence to restore the Building and Premises to substantially
the same condition as existed immediately before such Casualty, except for
modifications required by Regulations, and modifications to the Building or the
Project reasonably deemed desirable by Landlord; provided, however, that
Landlord shall not be required as part of the Restoration to repair or replace
any of the Alterations, furniture, equipment, fixtures, and other improvements
which may have been placed by, or at the request of, Tenant or other occupants
in the Building or the Premises. Landlord shall have no liability for any
inconvenience or annoyance to Tenant or injury to Tenant's business as a result
of any Casualty, regardless of the cause therefor. Base Rent, and Additional
Rent payable under Paragraph 3.2, shall abate if and to the extent a Casualty
damages the Premises or common areas in the Project required and essential for
access thereto and as a result thereof all or a material portion of the Premises
are rendered unfit for occupancy, and are not occupied by Tenant, for the period
of time commencing on the date Tenant vacates the portion of the Premises
affected on account thereof and continuing until the date the Restoration to be
performed by Landlord with respect to the Premises (and/or required common
areas) is substantially complete, as determined by Landlord's architect.
Landlord and Tenant agree that the provisions of this Paragraph 14 and the
remaining provisions of this Lease shall exclusively govern the rights and
obligations of the parties with respect to any and all damage to, or destruction
of, all or any portion of the Premises or the Project by Casualty, and Landlord
and Tenant hereby waive and release each and all of their respective common law
and statutory rights inconsistent herewith, whether now or hereinafter in effect
(including, without limitation, Sections 1932(2) and 1933(4) of the California
Civil Code, as amended from time to time).

15.   Parking. Tenant shall have the right to the nonexelusive use of such
portion of the parking facilities of the Project as are designated by Landlord
from time to time for such purpose for the parking of passenger-size motor
vehicles used by Tenant and Tenant Parties only and are not transferable without
Landlord's approval. The use of such parking facilities shall be subject to the
parking rules and regulations attached hereto as Exhibit E, as such rules and
regulations may be modified by Landlord from time to time, for the use of such
facilities.

l6.   Events of Default. Each of the following occurrences shall be an "Event of
Default" and shall constitute a material default and breach of this Lease by
Tenant: (a) any failure by Tenant to pay any installment of Base Rent,
Additional Rent or to make any other payment required to be made by Tenant
hereunder when due; (b) the abandonment or vacation of the Premises by Tenant,
provided, however, that unless Tenant is using the Premises for a retail use,
abandonment or vacation of the Premises shall not be an Event of Default so long
as no other Event of Default has occurred hereunder and provided Tenant has
given Landlord five (5) days' prior written notice of its intent to vacate the
Premises; (c) any failure by Tenant to execute and deliver any estoppel
certificate or other document or instrument described in Paragraphs 10
(insurance), 11 (subordination) or 21.2 (estoppel certificates) requested by
Landlord, where such failure continues for five (5) days after delivery of
written notice of such failure by Landlord to Tenant; (d) any failure by Tenant
to fully perform any other obligation of Tenant under this Lease, where such
failure continues for thirty (30) days (except where a shorter period of time is
specified in this Lease, in which case such shorter time period shall apply)
after delivery of written notice of such failure by Landlord to Tenant; (e) the
voluntary or involuntary filing of a petition by or against Tenant or any
general partner of Tenant (i) in any bankruptcy or other insolvency proceeding,
(ii) seeking any relief under any state or federal debtor relief law, (iii) for
the appointment of a liquidator or receiver for all or substantially all of
Tenant's property or for Tenant's interest in this Lease, or (iv) for the
reorganization or modification of Tenant's capital structure (provided, however,
that if such a petition is filed against Tenant, then such filing shall not be
an Event of Default unless Tenant fails to have the proceedings initiated by
such petition dismissed within sixty (60) days after the filing thereof); (f)
the default of any guarantor of Tenant's obligations hereunder under any
guaranty of this Lease, the attempted repudiation or revocation of any such
guaranty, or the participation by any such guarantor in any other event
described in this Paragraph 16 (as if this Paragraph 16 referred to such
guarantor in place of Tenant); or (g) any other event, act or omission which any
other provision of this Lease identifies as an Event of Default. Any notice of
any failure of Tenant required under this Paragraph 16 shall be in lieu of, and
not in addition to, any notice required under Section 1161 et seq. of the
California Code of Civil Procedure.

17.   Remedies. Upon the occurrence of any Event of Default by Tenant, Landlord
shall have, in addition to any other remedies available to Landlord at law or in
equity (all of which remedies shall be distinct, separate, and cumulative), the
option to pursue any one (1) or more of the following remedies, each and all of
which shall be cumulative and nonexelusive, without any notice or demand
whatsoever:

      (a) Terminate this Lease, and Landlord may recover from Tenant the
following: (i) the worth at the time of any unpaid rent which has been earned at
the time of such termination; plus (ii) the worth at the time of award of the
amount by which the unpaid rent which would have been earned after termination
until the time of award exceeds the amount of such rental loss that Tenant
proves could have been reasonably avoided;


Short Form Office - Net Lease (CA)     -6-
Version 10.1
<PAGE>

plus (iii) the worth at the time of award of the amount by which the unpaid rent
for the balance of the term after the time of award exceeds the amount of such
rental loss that Tenant proves could have been reasonably avoided; plus (iv) any
other amount necessary to compensate Landlord for all the detriment proximately
caused by Tenant's failure to perform its obligations under this Lease or which
in the ordinary course of things would be likely to result therefrom
(specifically including, without limitation, brokerage commissions and
advertising expenses incurred, expenses of remodeling the Premises or any
portion thereof for a new tenant, whether for the same or a different use, and
any special concessions made to obtain a new tenant); and (v) at Landlord's
election, such other amounts in addition to or in lieu of the foregoing as may
be permitted from time to time by applicable law. The term "rent" as used in
this Paragraph 17(a) shall be deemed to be and to mean all sums of every nature
required to be paid by Tenant pursuant to the terms of this Lease, whether to
Landlord or to others. As used in Paragraphs 17(a)(i) and (ii), above, the
"worth at the time of award" shall be computed by allowing interest at the
Default Rate, but in no case greater than the maximum amount of such interest
permitted by law. As used in Paragraph 17(a)(iii) above, the "worth at the time
of award" shall be computed by discounting such amount at the discount rate of
the Federal Reserve Bank of San Francisco at the time of award plus one percent
(1%).

      (b) Landlord shall have the remedy described in California Civil Code
Section 1951.4 (lessor may continue lease in effect after lessee's breach and
abandonment and recover rent as it becomes due, if lessee has the right to
sublet or assign, subject only to reasonable limitations). Accordingly, if
Landlord does not elect to terminate this Lease on account of any Event of
Default by Tenant, Landlord may, from time to time, without terminating this
Lease, enforce all of its rights and remedies under this Lease, including the
right to recover all Rent as it becomes due.

      (c) Landlord shall at all times have the rights and remedies (which shall
be cumulative with each other and cumulative and in addition to those rights and
remedies available under Paragraphs 17(a) and 17(b) above, or any law or other
provision of this Lease), without prior demand or notice except as required by
applicable law, to seek any declaratory, injunctive, or other equitable relief,
and specifically enforce this Lease, or restrain or enjoin a violation or breach
of any provision hereof.

      (d) Following the occurrence of three instances of payment of Rent more
than ten (10) days late in any twelve (12) month period, the late charge set

notice to Tenant, require that all remaining monthly installments of Rent
payable under this Lease shall be payable by cashier's check or electronic funds
transfer three (3) months in advance, and may require that Tenant increase the
Security Deposit to an amount equal to three times the current month's Rent at
the time of the most recent default. In addition, (i) upon the occurrence of an
Event of Default by Tenant, if the Premises or any portion thereof are sublet,
Landlord may, at its option and in addition and without prejudice to any other
remedies herein provided or provided by law, collect directly from the
sublessee(s) all rentals becoming due to the Tenant and apply such rentals
against other sums due hereunder to Landlord; (ii) without prejudice to any
other right or remedy of Landlord, if Tenant shall be in default under this
Lease, Landlord may cure the same at the expense of Tenant (A) immediately and
without notice in the case (1) of emergency, (2) where such default unreasonably
interferes with any other tenant in the Building, or (3) where such default will
result in the violation of any Regulation or the cancellation of any insurance
policy maintained by Landlord, and (B) in any other case if such default
continues for ten (10) days following the receipt by Tenant of notice of such
default from Landlord and all costs incurred by Landlord in curing such

Tenant all rights now and hereafter existing to redeem by order or judgment of
any court or by any legal process or writ, Tenant's right of occupancy of the
Premises after any termination of this Lease.

18.   Surrender of Premises. No act by Landlord shall be deemed an acceptance of
a surrender of the Premises, and no agreement to accept a surrender of the
Premises shall be valid unless it is in writing and signed by Landlord. At the
expiration or earlier termination of this Lease, Tenant shall deliver to
Landlord all keys (including any electronic access devices and the like) to the
Premises, and Tenant shall deliver to Landlord the Premises in the same
condition as existed on the date Tenant originally took possession thereof,
ordinary wear and tear excepted, provided that ordinary wear and tear shall not
include repair and clean up items. By way of example, but without limitation,
repair and clean up items shall include cleaning of all interior walls, carpets
and floors, replacement of damaged or missing ceiling or floor tiles, window
coverings or cover plates, removal of any Tenant-introduced markings, and repair
of all holes and gaps and repainting required thereby, as well as the removal
requirements below. In addition, prior to the expiration of the Term or any

shall request and shall restore the portion of the Premises affected by such
Alterations and such removal to its condition existing immediately prior to the
making of such Alterations, (b) Tenant shall remove from the Premises all
unattached trade fixtures, furniture, equipment and personal property located in

limitation, full restoration of all holes and gaps resulting from any such

Tenant not so removed shall, to the extent permitted under applicable
Regulations, be deemed to have been abandoned by Tenant and may be appropriated,
sold, stored, destroyed, or otherwise disposed of by Landlord without notice to
Tenant and without any obligation to account for such items.

19.   Holding Over. If Tenant holds over after the expiration or earlier
termination of the Term hereof, with or without the express or implied consent
of Landlord, Tenant shall become and be only a tenant at sufferance at a daily
rent equal to one-thirtieth of the greater of (a) the then prevailing monthly
fair market rental rate as determined by Landlord in its sole and absolute
discretion, or (b) two hundred percent (200%) of the monthly installment of Base
Rent (and estimated Additional Rent payable under Paragraph 3.2) payable by
Tenant immediately prior to such expiration or termination, and otherwise upon
the terms, covenants and conditions herein specified, so far as applicable, as
reasonably determined by Landlord. Neither any provision hereof nor any
acceptance by Landlord of any Rent after any such expiration or earlier
termination (including, without limitation, through any "lockbox") shall be
deemed a consent to any holdover hereunder or result in a renewal of this Lease
or an extension of the Term, or any waiver of any of Landlord's rights or
remedies with respect to such holdover. Notwithstanding any provision to the
contrary contained herein, (i) Landlord expressly reserves the right to require
Tenant to surrender possession of the Premises upon the expiration of the Term
or upon the earlier termination hereof or at any time during any holdover, and
the right to assert any remedy at law or in equity to evict Tenant and collect
damages in connection with any such holdover, and (ii) Tenant shall indemnify,
defend and hold Landlord harmless from and against any and all claims, demands,
actions, proceedings, losses, damages, liabilities, obligations, penalties,
costs and expenses, including, without limitation, all lost profits and other
consequential damages, attorneys' fees, consultants' fees and court costs
incurred or suffered by or asserted against Landlord by reason of Tenant's
failure to surrender the Premises on the expiration or earlier termination of
this Lease in accordance with the provisions of this Lease.

20.   Substitution Space. Upon at least sixty (60) days' prior written notice,
Landlord may relocate Tenant within the Project (or to any other facility owned
by Landlord within the vicinity of the Project) to space which is comparable in
size, utility and condition to the Premises. If Landlord relocates Tenant,
Landlord shall (a) reimburse Tenant for Tenant's reasonable out-of-pocket
expenses for moving Tenant's furniture, equipment and supplies from the Premises
to the relocation space and for reprinting Tenant's stationery of the same
quality and quantity as Tenant's stationery supply on hand immediately before
Landlord's notice to Tenant of the exercise of this relocation right, and (b)
improve the relocation space with


Short Form Office - Net Lease (CA)     -7-
Version 10.1
<PAGE>

improvements substantially similar to those Landlord is committed to provide or
has provided in the Premises under this Lease. Upon such relocation, the
relocation space shall be deemed to be the Premises and the terms of this Lease
shall remain in full force and shall apply to the relocation space; provided,
however, that (i) if the rentable area of the relocation space is smaller than
rentable area of the Premises, then Tenant shall be entitled (from and after the
relocation date) to a reduction in Base Rent in proportion to the reduction in
the rentable area of the Premises, with a corresponding reduction in Tenant's
Proportionate Share and (ii) if the rentable area of the relocation space is
larger than the rentable area of the Premises, then the Base Rent and Tenant's
Proportionate Share shall not be modified in any way.

21.   Miscellaneous.

      21.1 Landlord Transfers and Liability. Landlord may, without restriction,
sell, assign or transfer in any manner all or any portion of the Project, any
interest therein or any of Landlord's rights under this Lease. If Landlord
assigns its rights under this Lease, then Landlord shall automatically be
released from any further obligations hereunder, provided that the assignee
thereof assumes in writing all of Landlord's obligations hereunder accruing
after such assignment. The liability of Landlord to Tenant for any default by
Landlord under the terms of this Lease or with respect to any obligation or
liability related to the Premises or the Project shall be recoverable only from
the interest of Landlord in the Project, and neither Landlord nor any affiliate
thereof shall have any personal liability with respect thereto and in no case
shall Landlord be liable to Tenant for any lost profits, damage to business, or
any form of special, indirect or consequential damage on account of any breach
of this Lease.

      21.2 Estoppel Certificates; Financial Statements. At any time and from
time to time during the Term, Tenant shall, without charge, execute, acknowledge
and deliver to Landlord within ten (10) days after Landlord's request therefor,
an estoppel certificate in recordable form containing such factual
certifications and other provisions as are found in the estoppel certificate
forms requested by institutional lenders and purchasers. Tenant agrees in any
case that (a) the foregoing certificate may be relied on by anyone holding or
proposing to acquire any interest in the Project from or through Landlord or by
any mortgagee or lessor or prospective mortgagee or lessor of the Project or of
any interest therein and (b) the form of estoppel certificate shall be in the
form of, at Landlord's election, the standard form of such present or
prospective lender, lessor or purchaser (or any form substantially similar
thereto), or any other form that Landlord shall reasonably select. At the
request of Landlord from time to time, Tenant shall provide to Landlord within
ten (10) days of Landlord's request therefor Tenant's and any guarantor's
current financial statements.

      21.3 Notices. Notices, requests, consents or other communications desired
or required to be given by or on behalf of Landlord or Tenant under this Lease
shall be effective only if given in writing and sent by (a) registered or
certified United States mail, postage prepaid, (b) nationally recognized express
mail courier that provides written evidence of delivery, fees prepaid, or (c)
facsimile and United States mail, postage prepaid, and addressed as set forth in
the Basic Lease Information, or at such other address in the State of California
as may be specified from time to time, in writing, or, if to Tenant, at the
Premises. Any such notice, request, consent, or other communication shall only
be deemed given (i) if sent by registered or certified United States mail, on
the day it is officially delivered to or refused by the intended recipient, (ii)
if sent by nationally recognized express mail courier, on the date it is
officially recorded by such courier, (iii) if delivered by facsimile, on the
date the sender obtains written telephonic confirmation that the electronic
transmission was received, or (iv) if delivered personally, upon delivery or, if
refused by the intended recipient, upon attempted delivery.

      21.4 Payment by Tenant; Non-Waiver. Landlord's acceptance of Rent
(including, without limitation, through any "lockbox") following an Event of
Default shall not waive Landlord's rights regarding such Event of Default. No
waiver by Landlord of any violation or breach of any of the terms contained
herein shall waive Landlord's rights regarding any future violation of such
terms. Landlord's acceptance of any partial payment of Rent shall not waive
Landlord's rights with regard to the remaining portion of the Rent that is due,
regardless of any endorsement or other statement on any instrument delivered in
payment of Rent or any writing delivered in connection therewith; accordingly,
Landlord's acceptance of a partial payment of Rent shall not constitute an
accord and satisfaction of the full amount of the Rent that is due.

      21.5 Certain Rights Reserved by Landlord. Landlord hereby reserves and
shall have the following rights with respect to the Premises and the Project:
(a) to decorate and to make inspections, repairs, alterations, additions,
changes, or improvements, whether structural or otherwise, in and about the
Project, the Building, the Premises or any part thereof; to enter upon the
Premises and, during the continuance of any such work, to temporarily close
doors, entryways, public space, and corridors in the Project or the Building; to
interrupt or suspend temporarily Building services and facilities; to change the
name of the Building or the Project; and to change the arrangement and location
of entrances or passageways, doors, and doorways, corridors, elevators, stairs,
restrooms, common areas, or other public parts of the Building or the Project;
(b) to take such measures as Landlord deems advisable in good faith for the
security of the Building and its occupants; to temporarily deny access to the
Building to any person; and to close the Building after ordinary business hours
and on Sundays and Holidays, subject, however, to Tenant's right to enter when
the Building is closed after ordinary business hours under such rules and
regulations as Landlord may reasonably prescribe from time to time during the
Term; and (c) to enter the Premises at reasonable hours (or at any time in an
emergency) to perform repairs, to take any action authorized hereunder, or to
show the Premises to prospective purchasers or lenders, or, during the last six
(6) months of the Term, prospective tenants.

      21.6 Miscellaneous. If any clause or provision of this Lease is illegal,
invalid, or unenforceable under present or future laws, then the remainder of
this Lease shall not be affected thereby. This Lease may not be amended except
by instrument in writing signed by Landlord and Tenant. No provision of this
Lease shall be deemed to have been waived by Landlord unless such waiver is in
writing signed by Landlord. The terms and conditions contained in this Lease
shall inure to the benefit of and be binding upon the parties hereto, and upon
their respective successors in interest and legal representatives, except as
otherwise herein expressly provided. This Lease constitutes the entire agreement
between Landlord and Tenant regarding the subject matter hereof and supersedes
all oral statements and prior writings relating thereto. Tenant and the person
or persons signing on behalf of Tenant represent and warrant that Tenant has
full right and authority to enter into this Lease, and that all persons signing
this Lease on its behalf are authorized to do so. If Tenant is comprised of more
than one party, each such party shall be jointly and severally liable for
Tenant's obligations under this Lease. All exhibits and attachments attached
hereto are incorporated herein by this reference. This Lease shall be governed
by and construed in accordance with the laws of the State of California. In any
action which Landlord or Tenant brings to enforce its respective rights
hereunder, the unsuccessful party shall pay all costs incurred by the prevailing
party, including without limitation, reasonable attorneys' fees and court costs.
Tenant shall not record this Lease or any memorandum hereof. TO THE MAXIMUM
EXTENT PERMITTED BY LAWS, LANDLORD AND TENANT EACH WAIVE RIGHT TO TRIAL BY JURY
IN ANY LITIGATION ARISING OUT OF OR WITH RESPECT TO THIS LEASE. Submission of
this Lease to Tenant does not constitute an option or offer to lease and this
Lease is not effective otherwise until execution and delivery by both Landlord
and Tenant. This Lease may be executed in any number of counterparts, each of
which shall be deemed an original. Time is of the essence as to the performance
of each covenant hereunder in which time of performance is a factor.

                              RULES AND REGULATIONS

 1.   Driveways, sidewalks, halls, passages, exits, entrances, elevators,
      escalators and stairways shall not be obstructed by tenants or used by
      tenants for any purpose other than for ingress to and egress from their
      respective premises. The driveways, sidewalks, halls, passages, exits,
      entrances, elevators and stairways are not for the use of the general
      public and Landlord shall in all cases retain the right to control and
      prevent access thereto by all persons whose presence, in the judgment of
      Landlord, shall be prejudicial to the safety, character, reputation and
      interests of the Building, the Project and its tenants, provided that
      nothing herein contained shall be construed to prevent such access to
      persons with whom any tenant normally deals in the ordinary course of such
      tenant's business unless such persons are engaged in illegal activities.
      No tenant, and no employees or invitees of any tenant, shall go upon the
      roof of any Building, except as authorized by Landlord. No tenant, and no
      employees or invitees of any tenant shall move any common area furniture
      without Landlord's consent.

 2.   No sign, placard, banner, picture, name, advertisement or notice, visible
      from the exterior of the Premises or the Building or the common areas of
      the Building shall be inscribed, painted, affixed, installed or otherwise
      displayed by Tenant either on its Premises or any part of the Building or
      Project without the prior written consent of Landlord in Landlord's sole
      and absolute discretion. Landlord shall have the right to remove any such
      sign, placard, banner, picture, name, advertisement, or notice without
      notice to and at the expense of Tenant, which were installed or displayed
      in violation of this rule. If Landlord shall have given such consent to
      Tenant at any time, whether before or after the execution of Tenant's
      Lease, such consent shall in no way operate as a waiver or release of any
      of the provisions hereof or of the Lease, and shall be deemed to relate
      only to the particular sign, placard, banner, picture, name, advertisement
      or notice so consented to by Landlord and shall not be construed as
      dispensing with the necessity of obtaining the specific written consent of
      Landlord with respect to any other such sign, placard, banner, picture,
      name, advertisement or notice.

      All approved signs or lettering on doors and walls shall be printed,
      painted, affixed or inscribed at the expense of Tenant by a person or
      vendor approved by Landlord and shall be removed by Tenant at the time of
      vacancy at Tenant's expense.

 3.   The directory of the Building or Project will be provided exclusively for
      the display of the name and location of tenants only and Landlord reserves
      the right to charge for the use thereof and to exclude any other names
      therefrom.

 4.   No curtains, draperies, blinds, shutters, shades, screens or other
      coverings, awnings, hangings or decorations shall be attached to, hung or
      placed in, or used in connection with, any window or door on the Premises
      without the prior written consent of Landlord. In any event with the prior
      written consent of Landlord, all such items shall be installed inboard of
      Landlord's standard window covering and shall in no way be visible from
      the exterior of the Building. All electrical ceiling fixtures hung in
      offices or spaces along the perimeter of the Building must be fluorescent
      or of a quality, type, design, and bulb color approved by Landlord. No
      articles shall be placed or kept on the window sills so as to be visible
      from the exterior of the Building. No articles shall be placed against
      glass partitions or doors which Landlord considers unsightly from outside
      Tenant's Premises.

 5.   Landlord reserves the right to exclude from the Building and the Project,
      between the hours of 6 p.m. and 8 a.m. and at all hours on Saturdays,
      Sundays and legal holidays, all persons who are not tenants or their
      accompanied guests in the Building. Each tenant shall be responsible for
      all persons for whom it allows to enter the Building or the Project and
      shall be liable to Landlord for all acts of such persons.

      Landlord and its agents shall not be liable for damages for any error
      concerning the admission to, or exclusion from, the Building or the
      Project of any person.

      During the continuance of any invasion, mob, riot, public excitement or
      other circumstance rendering such action advisable in Landlord's opinion,
      Landlord reserves the right (but shall not be obligated) to prevent access
      to the Building and the Project during the continuance of that event by
      any means it considers appropriate for the safety of tenants and
      protection of the Building, property in the Building and the Project.

 6.   All cleaning and janitorial services for the Building and the Premises
      shall be provided exclusively through Landlord. Except with the written
      consent of Landlord, no person or persons other than those approved by
      Landlord shall be permitted to enter the Building for the purpose of
      cleaning the same. Tenant shall not cause any unnecessary labor by reason
      of Tenant's carelessness or indifference in the preservation of good order
      and cleanliness of its Premises. Landlord shall in no way be responsible
      to Tenant for any loss of property on the Premises, however occurring, or
      for any damage done to Tenant's property by the janitor or any other
      employee or any other person.

 7.   Tenant shall see that all doors of its Premises are closed and securely
      locked and must observe strict care and caution that all water faucets or
      water apparatus, coffee pots or other heat-generating devices are entirely
      shut off before Tenant or its employees leave the Premises, and that all
      utilities shall likewise be carefully shut off, so as to prevent waste or
      damage. Tenant shall be responsible for any damage or injuries sustained
      by other tenants or occupants of the Building or Project or by Landlord
      for noncompliance with this rule. On multiple-tenancy floors, all tenants
      shall keep the door or doors to the Building corridors closed at all times
      except for ingress and egress.

 8.   Tenant shall not use any method of heating or air-conditioning other than
      that supplied by Landlord. As more specifically provided in Tenant's lease
      of the Premises, Tenant shall not waste electricity, water or
      air-conditioning and agrees to cooperate fully with Landlord to assure the
      most effective operation of the Building's heating and air-conditioning,
      and shall refrain from attempting to adjust any controls other than room
      thermostats installed for Tenant's use.

 9.   Landlord will furnish Tenant free of charge with two keys to each door in
      the Premises. Landlord may make a reasonable charge for any additional
      keys, and Tenant shall not make or have made additional keys. Tenant shall
      not alter any lock or access device or install a new or additional lock or
      access device or bolt on any door of its Premises, without the prior
      written consent of Landlord. If Landlord shall give its consent, Tenant
      shall in each case furnish Landlord with a key for any such lock. Tenant,
      upon the termination of its tenancy, shall deliver to Landlord the keys
      for all doors which have been furnished to Tenant, and in the event of
      loss of any keys so furnished, shall pay Landlord therefor.

10.   The restrooms, toilets, urinals, wash bowls and other apparatus shall not
      be used for any purpose other than that for which they were constructed
      and no foreign substance of any kind whatsoever shall be thrown into them.
      The expense of any breakage, stoppage, or damage resulting from violation
      of this rule shall be borne by the tenant who, or whose employees or
      invitees, shall have caused the breakage, stoppage, or damage.

                               TENANT'S INSURANCE

Tenant's Insurance. Tenant shall, at Tenant's sole cost and expense, procure and
keep in effect from the date of this Lease and at all times until the end of the
Term, the following insurance coverage:

1.    Property Insurance. Insurance on all personal property and fixtures of
      Tenant and all improvements made by or for Tenant to the Premises on an
      "All Risk" or "Special Form" basis, for the full replacement value of such
      property.

2.    Liability Insurance. Commercial General Liability insurance written on an
      ISO CG 00 01 10 93 or equivalent form, on an occurrence basis, with a per
      occurrence limit of at least $2,000,000, and a minimum general aggregate
      limit of at least $3,000,000, covering bodily injury and property damage
      liability occurring in or about the Premises or arising out of the use and
      occupancy of the Premises or the Project by Tenant or any Tenant Party.
      Such insurance shall include contractual liability coverage insuring
      Tenant's indemnity obligations under this Lease, and shall be endorsed to
      name Landlord, any Holder of a Security Instrument and any other party
      specified by Landlord as an additional insured with regard to liability
      arising out of the ownership, maintenance or use of the Premises.

3.    Worker's Compensation and Employer's Liability Insurance. (a) Worker's
      Compensation Insurance as required by any Regulation, and (b) Employer's
      Liability Insurance in amounts not less than $1,000,000 each accident for
      bodily injury by accident and for bodily injury by disease, and for each
      employee for bodily injury by disease.

4.    Commercial Auto Liability Insurance. Commercial auto liability insurance
      with a combined limit of not less than One Million Dollars ($1,000,000)
      for bodily injury and property damage for each accident. Such insurance
      shall cover liability relating to any auto (including owned, hired and
      non-owned autos).

5.    Alterations Requirements. In the event Tenant shall desire to perform any
      Alterations, Tenant shall deliver to Landlord, prior to commencing such
      Alterations (i) evidence satisfactory to Landlord that Tenant carries
      "Builder's Risk" insurance covering construction of such Alterations in an
      amount and form approved by Landlord, (ii) such other insurance as
      Landlord shall nondiscriminatorily require, and (iii) a lien and
      completion bond or other security in form and amount satisfactory to
      Landlord.

6.    General Insurance Requirements. All coverages described in this Exhibit D
      shall be endorsed to (i) provide Landlord with thirty (30) days' notice of
      cancellation or change in terms; (ii) waive all rights of subrogation by
      the insurance carrier against Landlord; and (iii) be primary and
      non-contributing with Landlord's insurance. If at any time during the Term
      the amount or coverage of insurance which Tenant is required to carry
      under this Exhibit D is, in Landlord's reasonable judgment, materially
      less than the amount or type of insurance coverage typically carried by
      owners or tenants of properties located in the general area in which the
      Premises are located which are similar to and operated for similar
      purposes as the Premises or if Tenant's use of the Premises should change
      with or without Landlord's consent, Landlord shall have the right to
      require Tenant to increase the amount or change the types of insurance
      coverage required under this Exhibit D. All insurance policies required to
      be carried by Tenant under this Lease shall be written by companies rated
      AVII or better in "Best's Insurance Guide" and authorized to do business
      in the State of California. Deductible amounts under all insurance
      policies required to be carried by Tenant under this Lease shall not
      exceed $l0,000 per occurrence. Tenant shall deliver to Landlord on or
      before the Term Commencement Date, and thereafter at least thirty (30)
      days before the expiration dates of the expired policies, certified copies
      of Tenant's insurance policies, or a certificate evidencing the same
      issued by the insurer thereunder, and, if Tenant shall fail to procure
      such insurance, or to deliver such policies or certificates, Landlord may,
      at Landlord's option and in addition to Landlord's other remedies in the
      event of a default by Tenant under the Lease, procure the same for the
      account of Tenant, and the cost thereof (with interest thereon at the
      Default Rate) shall be paid to Landlord as Additional Rent.

Landlord's Insurance. All insurance maintained by Landlord shall be for the sole
benefit of Landlord and under Landlord's sole control.

1.    Property Insurance. Landlord agrees to maintain property insurance
      insuring the Building against damage or destruction due to risk including
      fire, vandalism, and malicious mischief in an amount not less than the
      replacement cost thereof, in the form and with deductibles and
      endorsements as selected by Landlord. At its election, Landlord may
      instead (but shall have no obligation to) obtain "All Risk" coverage, and
      may also obtain earthquake, pollution, and/or flood insurance in amounts
      selected by Landlord.

2.    Optional Insurance. Landlord, at Landlord's option, may also (but shall
      have no obligation to) carry (i) insurance against loss of rent, in an
      amount equal to the amount of Base Rent and Additional Rent that Landlord
      could be required to abate to all Building tenants in the event of
      condemnation or casualty damage for a period of twelve (12) months; and
      (ii) liability insurance and such other insurance as Landlord may deem
      prudent or advisable, including, without limitation, liability insurance
      in such amounts and on such terms as Landlord shall determine. Landlord
      shall not be obligated to insure, and shall have no responsibility
      whatsoever for any damage to, any furniture, machinery, goods, inventory
      or supplies, or other personal property or fixtures which Tenant may keep
      or maintain in the Premises, or any leasehold improvements, additions or
      alterations within the Premises.
