  • Commercial Lease. Start a state-specific lease for the rental of commercial property. Specify the term and rent due, as well as whether the landlord or tenant is responsible for property taxes, insurance, and maintenance and repairs.
  • Commercial Sublease. When a tenant vacates commercial property before the lease term has expired, it may be able to rent the premises to a third party. The tenant would be the sublessor and the third party would be the sublessee. Besides preparing a sublease, both parties will want to review the provisions for assignment or subletting in the original lease agreement between the landlord and the sublessor.
  • Sublease Agreement. Tenants of residential property should prepare a sublease agreement if they are seeking to sublease a room or the entire apartment or house to a third party. All parties should review the original lease agreement to see if there are any restrictions on subletting or assigning the premises.
  • Triple Net Lease. Triple net leases are a type of commercial leases where the tenant has to pay for property taxes, insurance, utilities, and maintenance, in addition to the monthly rent.
  • Office Space Lease. When renting an office space, tenants should understand the amount of the rent and duration of the lease. Other important terms include whether the space can be subleased, which parties are responsible for maintenance, and whether any furniture and furnishings will be provided.

                                     LEASE

THIS LEASE is made as of the eighth day of December, 1997, by and between
Spieker Properties, L.P., a California limited partnership (hereinafter called
"Landlord"), and Selectica, Inc., a California corporation (hereinafter called
"Tenant").

                                  1. PREMISES

     Landlord leases to Tenant and Tenant leases from Landlord, upon the terms
and conditions hereinafter set forth, those premises (the "Premises") outlined
in red on Exhibit B and described in the Basic Lease Information. The Premises
shall be all or part of a building (the "Building") and of a project (the
"Project") which may consist of more than one building, as described in the
Basic Lease Information. The Building and Project are outlined in blue and green
respectively on Exhibit B. Landlord and Tenant acknowledge that physical
changes may occur from time to time in the Premises, Building or Project, and
that the number of buildings which constitute the Project may change from time
to time, which may result in an adjustment in Tenant's Proportionate Share, as
defined in the Basic Lease Information, as provided in Paragraph 7.A.

                      2. POSSESSION AND LEASE COMMENCEMENT

A.   EXISTING IMPROVEMENTS. If this Lease pertains to Premises in which the
interior improvements have already been constructed ("Existing Improvements"),
the provisions of this Paragraph 2.A. shall apply and the term commencement date
("Term Commencement Date") shall be the earlier of the date on which: (1) Tenant
takes possession of some or all of the Premises; or (2) Landlord notifies Tenant
that Tenant may occupy the Premises. If for any reason Landlord cannot deliver
possession of the Premises to Tenant on the scheduled Term Commencement Date,
Landlord shall not be subject to any liability therefor, nor shall Landlord be
in default hereunder nor shall such failure affect the validity of this Lease,
and Tenant agrees to accept possession of the Premises at such time as Landlord
is able to deliver the same, which date shall then be deemed the Term
Commencement Date. Tenant shall not be liable for any Rent (defined below) for
any period prior to the Term Commencement Date. Tenant acknowledges that Tenant
has inspected and accepts the Premises in their present condition, "as is," and
as suitable for, the Permitted Use (as defined below), and for Tenant's intended
operations in the Premises. Tenant agrees that the Premises and other
improvements are in good and satisfactory condition as of when possession was
taken. Tenant further acknowledges that no representations as to the condition
or repair of the Premises nor promises to alter, remodel or improve the Premises
have been made by Landlord or any agents of Landlord unless such are expressly
set forth in the Lease. Upon Landlord's request, Tenant shall execute and return
to Landlord a "Start-Up Letter" in which Tenant shall agree, among other things,
to acceptance of the Premises and to the determination of the Term Commencement
Date, in accordance with the terms of this Lease, 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.

B.   CONSTRUCTION OF IMPROVEMENTS. If this Lease pertains to a Building to be
constructed or improvements to be constructed within a  Building, the
provisions of this Paragraph 2.B. shall apply in lieu of the provisions of
Paragraph 2.A. above and the term commencement date ("Term Commencement Date")
shall be the earlier of the date on which: (1) Tenant takes possession of some
or all of the Premises; or (2) the improvements to be constructed or performed
in the Premises by Landlord (if any) shall have been substantially completed in
accordance with the plans and specifications, if any, described on Exhibit C
and Tenant's taking of possession of the Premises or any part thereof shall
constitute Tenant's confirmation of substantial completion for all purposes
hereof, whether or not substantial completion of the Building or Project shall
have occurred. If for any reason Landlord cannot deliver possession of the
Premises to Tenant on the scheduled Term Commencement Date, Landlord shall not
be subject to any liability therefor, nor shall Landlord be in default
hereunder nor shall such failure affect the validity of this Lease, and Tenant
agrees to accept possession of the Premises at such time as such improvements
have been substantially completed, which date shall then be deemed the Term
Commencement Date. Tenant shall not be liable for any Rent for any period prior
to the Term Commencement Date (but without affecting any obligations of Tenant
under any improvement agreement appended to this Lease). In the event of any
dispute as to substantial completion of work performed or required to be
performed by Landlord, the certificate of Landlord's architect or general
contractor shall be conclusive. Substantial completion shall have occurred
notwithstanding Tenant's submission of a punchlist to Landlord, which Tenant
shall submit, if at all, within three (3) business days after the Term
Commencement Date or otherwise in accordance with any improvement agreement
appended to this Lease. Upon Landlord's request, Tenant shall promptly execute
and return to Landlord a Start-Up Letter in which Tenant shall agree, among
other things, to acceptance of the Premises and to the determination of the
Term Commencement Date, in accordance with the terms of this Lease, 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. TERM

     The term of this Lease (the "Term") shall commence on the Term
Commencement Date and continue in full force and effect for the number of
months specified as the Length of Term in the Basic Lease Information or until
this Lease is terminated as otherwise provided herein. If the Term Commencement
Date is a date other than the first day of the calendar month, the Term shall
be the number of months of the Length of Term in addition to the remainder of
the calendar month following the Term Commencement Date.

                                     4. USE

the Basic Lease Information ("Permitted Use") and for no other use or purpose.

Parties") in such a manner that Tenant and Tenant's Parties cumulatively do not
exceed the occupancy density (the "Occupancy Density") or the parking density
(the "Parking Density") specified in the Basic Lease Information at any time.
Tenant shall pay the Parking Charge specified in the Basic Lease Information as
Additional Rent (as hereinafter defined) hereunder. So long as Tenant is

may from time to time prescribe. Landlord reserves the right to alter or modify
the common area from time to time, including the configuration thereof and the
amenities and facilities which Landlord may determine to provide from time to
time.

B.   LIMITATIONS. Tenant shall not permit any odor, smoke, dust, gas,
substances, noise or vibrations to emanate from the Premises or from any
portion of the common areas as a result of Tenant's or any Tenant's Party's use
thereof, nor take any action which would constitute a nuisance or would
disturb, obstruct or endanger any other tenants or occupants of the Building or
Project or elsewhere, or interfere with their use of their respective premises
or common areas. Storage outside the Premises of materials, vehicles or any
other items is prohibited. Tenant shall not use or allow the Premises to be

on or about the Premises. Tenant shall not allow any sale by auction upon the
Premises, or place any leads upon the floors, walls or ceilings which could
endanger the structure, or place any harmful substances in the drainage system
of the Building or Project. No waste, materials or refuse shall be dumped upon
or permitted to remain outside the Premises. Landlord shall not be responsible
to Tenant for the non-compliance by any other tenant or occupant of the
Building or Project with any of the above-referenced rules or any other terms
or provisions of such tenant's or occupant's lease or other contract.

C.   COMPLIANCE WITH REGULATIONS. By entering the Premises, Tenant accepts the
Premises in the condition existing as of the date of such entry. Tenant shall at
its sole cost and expense strictly comply with all existing or future applicable
municipal, State and federal and other governmental statutes, rules,
requirements, regulations, laws and ordinances, including zoning ordinances and
regulations, and covenants, ?? and restrictions of record governing and relating
to the use, occupancy or possession of the Premises, to Tenant's use of the
common areas, or to the use, storage, generation or disposal of Hazardous
Materials (hereinafter defined) (collectively "Regulations"). Tenant shall at
its sole and expense obtain any and all licenses or permits necessary for
Tenant's use of the Premises. Tenant shall at its sole cost and expense promptly
comply with the requirements of any board of fire underwriters or other similar
body now or hereafter constituted. Tenant shall not do or permit anything to be
done in, or, under or about the Project or bring or keep anything which will in
any way increase the rate of any insurance upon the Premises, Building or
Project or upon any contents herein or cause a cancellation of said insurance or
otherwise affect said insurance in any manner. Tenant shall indemnify, defend,
protect and hold Landlord harmless from and against any loss, cost, expense,
damage, attorneys' fees or liability arising out of the failure of Tenant to
comply with any Regulation. Tenant's obligations pursuant to the foregoing
indemnity shall survive the expiration or earlier termination of this Lease.

D.   HAZARDOUS MATERIALS. As used in this Lease, "Hazardous Materials" shall
include, but not be limited to, hazardous, toxic and radioactive materials and
those substances defined as "hazardous substances," "hazardous materials,"
"hazardous waste," "toxic substances," or other similar designations to any
Registration. Tenant shall not cause, or allow any of Tenant's Parties to cause,
any Hazardous Materials to be handled, used, generated, moved, released or
disposed of in, on, under or about the Premises, the Building or the Project or
surrounding land or environment in violation of any Regulations. Tenant must
obtain Landlord's written consent prior to the introduction of any Hazardous
Materials on to the Project. Notwithstanding the foregoing, Tenant may handle,
store, use and dispose of products containing small quantities of Hazardous
Materials for "general office purposes" (such as toner for copiers) to the
extent customary and necessary for the Permitted Use of the Premises, provided
that Tenant shall always handle, store, use and dispose of any such Hazardous
Materials in a safe and lawful manner and never allow such Hazardous Materials
to contaminate the Premises, Building, or Project or surrounding land or
environment. Tenant shall immediately notify Landlord in writing of any
Hazardous Materials' contamination of any portion of the Project of which Tenant
becomes aware, whether or not caused by Tenant. Landlord shall have the right at
all reasonable times to inspect the Premises and to conduct tests and
investigations to determine whether Tenant is in compliance with the foregoing
provisions, the costs of all such inspections, tests and investigations to be
borne by Tenant. Tenant shall indemnify, defend (by counsel reasonably
acceptable to Landlord), protect and hold Landlord harmless from and against any
and all claims, liabilities, losses, costs, loss of rents, liens, damages,
injuries or expenses (including attorneys' and consultants' fees and court
costs), demands, causes of action, or judgments directly or indirectly arising
out of or related to the use, generation, storage, release, or disposal of
Hazardous Materials by Tenant or any of Tenant's Parties in, on, under and about
the Premises, the Building or the Project or surrounding land or environment,
which indemnity shall include, without limitation, damages for personal or
bodily injury, property damages, damage to the environment or natural resources
occurring on or off the Premises, loans attributable to discrimination in value
or adverse affects on marketability, the cost of any investigation, monitoring,
government oversight, repair, removal, remediation, restoration, abandonment and
disposal, and the preparation of any closure or other required plans, whether
such action is required or necessary prior to or following the expiration or
earlier termination of this Lease. Neither the consent by Landlord to the use,
generation, storage, release or disposal of Hazardous Materials nor the strict
compliance by Tenant with all laws pertaining to Hazardous Materials shall
excuse Tenant from Tenant's obligation of indemnification pursuant to this
Paragraph 4.D. Tenant's obligations pursuant to the foregoing indemnity shall
survive the expiration or earlier termination of this Lease.

5. RULES AND REGULATIONS

     Tenant shall faithfully observe and comply with the building rules and

Building or Project. Tenant shall cause Tenant's Parties to comply with such

Lease Information, or to such other place as Landlord may from time to time
designate in writing. Base Rent for the first full month of the Term shall be

The Base Rent payable by Tenant hereunder is subject to adjustment as provided

the manner set forth below. Tenant shall pay the applicable Tenant's
Proportionate Share of each such Operating Expenses. Landlord and Tenant
acknowledge that if the number of buildings which constitute the Project
increases or decreases, or if physical changes are made to the Premises,
Building or Project or the configuration of any thereof, Landlord may at its
discretion reasonably adjust Tenant's Proportionate Share of the Building or
Project to reflect the change. Landlord's determination of Tenant's
Proportionate Share of the Building and of the Project shall be conclusive so
long as it is reasonably and consistently applied. "Operating Expenses" shall
mean all expenses and costs of every kind and nature which Landlord shall pay or
become obligated to pay, because of or in connection with the ownership,
management, maintenance, repair, preservation, replacement and operation of the

<PAGE>   5
reasonable manner) other than those expenses and costs which are specifically
attributable to Tenant or which are expressly made the financial responsibility
of Landlord pursuant to this Lease. Operating Expenses shall include, but are
not limited to, the following:

     (1)  TAXES. All real property taxes and assessments, possessory interest
     taxes, sales taxes, personal property taxes, business or license taxes or
     fees, gross receipts taxes, service payments in lieu of such taxes or fees,
     annual or periodic license or use fees, excises, transit charges, and
     other impositions, general and special, ordinary and extraordinary,
     unforeseen as well as foreseen, of any kind (including fees "in-lieu" of

     or any tax, assessment or fee imposed in substitution, partially or
     totally, of any of the above. Operating Expenses shall also include any
     taxes, assessments, reassessments, or other fees or impositions with

     repair, use or occupancy of the Premises, Building or Project or any
     portion thereof, including, without limitation, by or for Tenant, and all
     increases therein or reassessments thereof whether the increases or
     reassessments result from increased rate and/or valuation (whether upon a
     transfer of the Building or Project or any portion thereof or any interest
     therein or for any other reason). If it shall not be lawful for Tenant to
     reimburse Landlord for all or any part of such taxes, the monthly rental
     payable to Landlord under this Lease shall be revised to net Landlord the

     have been payable to Landlord prior to the payment of any such taxes.

     (2)  INSURANCE. All insurance premiums and costs, including, but not

          lighting, and any other items or areas which affect the operation or
          appearance of the Building or Project, which determination shall be at
          Landlord's discretion, except for: those items expressly made the
          financial responsibility of Landlord pursuant to Paragraph 10 hereof;
          those items to the extent paid for by the proceeds of insurance; and
          those items attributable solely or jointly to specific tenants of the
          Building or Project.

          (b)  Repairs, replacements, and general maintenance shall include the
          cost of any capital improvements made to or capital assets acquired
          for the Project or Building that in Landlord's discretion may reduce
          any other Operating Expenses, including present or future repair work,
          are reasonably necessary for the health and safety of the occupants of
          the Building or Project, or are required under any Regulation, such
          costs or allocable portions thereof to be amortized over such
          reasonable period as Landlord shall determine, together with interest
          on the unamortized balance at the publicly announced "prime rate"
          charged by Wells Fargo Bank, N.A. (San Francisco) or its successor at
          the time such improvements or capital assets are constructed or
          acquired, plus two (2) percentage points, or in the absence of such
          prime rate, then at the U.S. Treasury six-month market note (or bond,
          if so designated) rate as published by any national financial
          publication selected by Landlord, plus four (4) percentage points, but
          in no event more than the maximum rate permitted by law.

          (c)  Payment under or for any easement, licence, permit, operating
          agreement, declaration, restrictive covenant or instrument relating to
          the Building or Project.

          (d)  All expenses related to services and costs of supplies and
          equipment used in maintaining the Premises, Building and Project, the
          equipment therein and the adjacent sidewalks, driveways, parking and
          service areas, including, without limitation, expenses related to
          service agreements regarding security, fire and other alarm systems,
          janitorial services, window cleaning, elevator maintenance, Building
          exterior maintenance, landscaping and expenses related to the
          administration, management and operation of the Project, including
          without limitation salaries, wages and benefits and management office
          rent.

          (e)  The cost of supplying any services and utilities which benefit
          all or a portion of the Premises, Building or Project, including
          without limitation services and utilities provided pursuant to
          Paragraph 15 hereof.

          (f)  A management and accounting cost recovery fee equal to five
          percent (5%) of the sum of the Project's base rents and Operating
          Expenses (other than such management and accounting fee).

     If the rentable area of the Building and/or Project is not fully occupied
during any fiscal year of the Term as determined by Landlord, an adjustment may
be made in Landlord's discretion in computing the Operating Expenses for such
year so that Tenant pays an equitable portion of all variable items (e.g.,
utilities, janitorial services and other component expenses that are affected
by variations in occupancy levels) of Operating Expenses, as reasonably
determined by Landlord; provided, however, that in no event shall Landlord be
entitled to collect in excess of one hundred percent (100%) of the total
Operating Expenses from all of the tenants in the Building or Project, as the
case may be.

     Operating Expenses shall not include specific costs incurred for the
account of, separately billed to and paid by specific tenants of the Building
or Project. Notwithstanding anything herein to the contrary, in any instance
wherein Landlord, in Landlord's sole discretion, deems Tenant to be responsible
for any amounts greater than Tenant's Proportionate Share, Landlord shall have
the right to allocate costs in any manner Landlord deems appropriate.

     The above enumeration of services and facilities shall not be deemed to
impose an obligation on Landlord to make available or provide such services or
facilities except to the extent if any that Landlord has specifically agreed
elsewhere in this Lease to make the same available or provide the same. Without
limiting the generality of the foregoing, Tenant acknowledges and agrees that
it shall be responsible for providing adequate security for its use of the
Premises, the Building and the Project and that Landlord shall have no
obligation or liability with respect thereto, except to the extent if any that
Landlord has specifically agreed elsewhere in this Lease to provide the same.

B.   PAYMENT OF ESTIMATED OPERATING EXPENSES. "Estimated Operating Expenses"
for any particular year shall mean Landlord's estimate of the Operating
Expenses for such fiscal year made with respect to such fiscal year as
hereinafter provided. Landlord shall have the right from time to time to revise
its fiscal year and interim accounting periods so long as the periods as so
revised are reconciled with prior periods in a reasonable manner. During the
last month of each fiscal year during the Term, or as soon thereafter as
practicable, Landlord shall give Tenant written notice of the Estimated
Operating Expenses for the ensuing fiscal year. Tenant shall pay Tenant's



                                       5
<PAGE>   6
Proportionate Share of the Estimated Operating Expenses with installments of
Base Rent for the fiscal year to which the Estimated Operating expenses applies
in monthly installments on the first day of each calendar month during such
year, in advance. If at any time during the course of the fiscal year, Landlord
determines that Operating Expenses are projected to vary from the then
Estimated Operating Expenses by more than ten percent (10%), Landlord may, by
written notice to Tenant, revise the Estimated Operating Expenses for the
balance of such fiscal year, and Tenant's monthly installments for the
remainder of such year shall be adjusted so that by the end of such fiscal year
Tenant has paid to Landlord Tenant's Proportionate Share of the revised
Estimated Operating Expenses for such year.

C.  COMPUTATION OF OPERATING EXPENSES ADJUSTMENT. "Operating Expense Adjustment"
shall mean the difference between Estimated Operating Expenses and actual
Operating Expenses for any fiscal year determined as hereinafter provided.
Within one hundred twenty (120) days after the end of each fiscal year, or as
soon thereafter as practicable, Landlord shall deliver to Tenant a statement of
actual Operating Expenses for the fiscal year just ended, accompanied by a
computation of Operating Expense Adjustment. If such statement shows that
Tenant's payment based upon Estimated Operating Expenses is less than Tenant's
Proportionate Share of Operating Expenses, then Tenant shall pay to Landlord the
difference within twenty (20) days after receipt of such statement. If such
statement shows that Tenant's payments of Estimated Operating Expenses exceed
Tenant's Proportionate Share of Operating expenses, then (provided that Tenant
is not in default under this Lease) Landlord shall pay to Tenant the difference
within twenty (20) days after delivery of such statement to Tenant. If this
Lease has been terminated or the Term hereof has expired prior to the date of
such statement, then the Operating Expense Adjustment shall be paid by the
appropriate party within twenty (20) days after the date of delivery of the
statement. Should this Lease commence or terminate at any time other than the
first day of the fiscal year, Tenant's Proportionate Share of the Operating
Expense Adjustment shall be prorated based on a month of 30 days and the number
of calendar months during such fiscal year that this Lease is in effect.
Notwithstanding anything to the contrary contained in Paragraph 7.A or 7.B,
Landlord's failure to provide any notices or statements within the time periods
specified in those paragraphs shall in no way excuse Tenant from its obligation
to pay Tenant's Proportionate Share of Operating Expenses.

D.  NET LEASE. 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 7.A, incurred in connection with the ownership, management,
maintenance, repair, preservation, replacement and operation of the Building
and/or Project and such additional facilities now and in subsequent years as
may be determined by Landlord to be necessary to the Building and/or Project.

E.  TENANT AUDIT. If Tenant shall dispute the amount set forth in any statement
provided by Landlord under Paragraph 7.B, or 7.C, above, Tenant shall have the
right, not later than twenty (20) days following receipt of such statement and
upon the condition that Tenant shall first deposit with Landlord the full
amount in dispute, to cause Landlord's books and records with respect to
Operating Expenses for such fiscal year to be audited by certified public
accountants selected by Tenant and subject to Landlord's reasonable right of
approval. The Operating Expense Adjustment shall be appropriately adjusted on
the basis of such audit. If such audit discloses a liability for a refund in
excess of ten percent (10%) of Tenant's Proportionate Share of the Operating
Expenses previously reported, the cost of such audit shall be borne by
Landlord; otherwise the cost of such audit shall be paid by Tenant. If Tenant
shall not request an audit in accordance with the provisions of this Paragraph
7.E. within twenty (20) days after receipt of Landlord's statement provided
pursuant to Paragraph 7.B. or 7.C., such statement shall be final and binding
for all purposes hereof.

                       8.  INSURANCE AND INDEMNIFICATION

A.  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 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 carry
    insurance against loss of rent, in an amount equal to the amount of Base
    Rent and Additional Rent that Landlord could be required to abase to all
    Building tenants in the event of condemnation or casualty damage for a
    period of twelve (12) months. Landlord may also carry 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.

B.  TENANT'S INSURANCE.

    (1)  PROPERTY INSURANCE. Tenant shall procure at Tenant's sole cost and
    expense and keep in effect from the date of this Lease and at all times
    until the end of the Term, insurance on all personal property and fixtures
    of Tenant and all improvements, additions or alterations made by or for
    Tenant to the Premises on an "All Risk" basis, insuring such property for
    the full replacement value of such property.

    (2)  LIABILITY INSURANCE. Tenant shall procure at Tenant's sole cost and
    expense and keep in effect from the date of this Lease and at all times
    until the end of the Term Commercial General Liability insurance covering
    bodily injury and property damage liability occurring in or about the
    Premises or arising out of the use and occupancy of the Premises and the
    Project, and any part of either, and any areas adjacent thereto, and the
    business operated by Tenant or by any other occupant of the Premises. Such
    insurance shall include Broad Form Contractual Liability insurance coverage
    insuring all of Tenant's indemnity obligations under this Lease. Such
    coverage shall have a minimum combined single limit of liability of at least
    Two Million Dollars ($2,000,000.00), and a minimum general aggregate limit
    of Three Million Dollars ($3,000,000.00), with an "Additional Insured -
    Managers or Lessors of Premises Endorsement." All such policies shall be
    written to apply to all bodily injury, property damage or loss, personal
    injury and other covered loss, however occasioned, occurring during the
    policy term, shall be endorsed to add Landlord and any party holding an
    interest to which this Lease may be subordinated as an additional insured,
    and shall provide that such coverage shall be "primary" and non-contributing
    with any insurance maintained by Landlord, which shall be excess insurance
    only. Such coverage shall also contain endorsements; (i) deleting any
    employee exclusion on personal injury coverage; (ii) including employees as
    additional insureds: and (iii) providing for coverage of employer's
    automobile non-ownership liability. All such insurance shall provide for the
    severability of interests of insureds; and shall be written on an
    "occurrence" basis, which shall afford coverage for all claims based on
    acts, omissions, injury ad damage, which occurred or arose (or the onset of
    which occurred or arose) in whole or in part during the policy period.

    (3)  WORKERS' COMPENSATION AND EMPLOYERS' LIABILITY INSURANCE. Tenant shall
    carry Workers' Compensation Insurance as required by any Regulation,
    throughout the Term at Tenant's sole cost and expense. Tenant shall also
    carry


                                       5
<PAGE>   7
       Employers' Liability insurance in amounts not less than One Million
       Dollars ($1,000,000) each accident for bodily injury by accident; One
       Million Dollars ($1,000,000) policy limit for bodily injury by disease;
       and One Million Dollars ($1,000,000) each employee for bodily injury by
       disease, throughout the Term at Tenant's sole cost and expense.

       (4)   GENERAL INSURANCE REQUIREMENTS. All coverages described in this
       Paragraph 8.B. shall be endorsed to (i) provide Landlord with thirty (30)
       days' notice of cancellation or change in terms; and (ii) waive all
       rights of subrogation by the insurance carrier against Landlord. If at
       any time during the Term the amount or coverage of insurance which Tenant
       is required to carry under this Paragraph 8.B. 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 Paragraph 8.B. All
       insurance policies required to be carried under this Lease shall be
       written by companies rated A VIII or better in "Best's Insurance Guide"
       and authorized to do business in the State of California. In any event
       deductible amounts shall not exceed Five Thousand Dollars ($5,000).
       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
       hereunder, procure the same for the account of Tenant, and the cost
       thereof shall be paid to Landlord as Additional Rent.

C.     INDEMNIFICATION. Tenant shall indemnify, defend by counsel reasonably
acceptable to Landlord, protect and hold Landlord harmless from and against any
and all claims, liabilities, losses, costs, loss of rents, liens, damages,
injuries or expenses, including reasonable attorneys' and consultants' fees and
court costs, demands, causes of action, or judgments, directly or indirectly
arising out of or related to: (1) claims of injury to or death of persons or
damage to property occurring or resulting directly or indirectly from the use
or occupancy of the Premises by Tenant or Tenant's Parties, or from activities
or failures to act of Tenant or Tenant's Parties; (2) claims arising from work
or labor performed, or for materials or supplies furnished to or at the request
or for the account of Tenant in connection with performance of any work done
for the account of Tenant within the Premises or Project; (3) claims arising
from any breach or default on the part of Tenant in the performance of any
covenant contained in this Lease; and (4) claims arising from the negligence
or intentional acts or omissions of Tenant or Tenant's Parties. The foregoing
indemnity by Tenant shall not be applicable to claims to the extent arising
from the gross negligence or willful misconduct of Landlord. The provisions of
this Paragraph shall survive the expiration or earlier termination of this
Lease.

                           9.   WAIVER OF SUBROGATION

       To the extent permitted by law and without affecting the coverage
provided by insurance to be maintained hereunder or any other rights or
remedies, Landlord and Tenant each waive any right to recover against the other
for: (a) damages for injury to or death of persons; (b) damages to property,
including personal property; (c) damages to the Premises or any part thereof;
and (d) claims arising by reasons of the foregoing due to hazards covered by
insurance maintained or required to be maintained pursuant to this Lease to the
extent of proceeds recovered therefrom, or proceeds which would have been
recoverable therefrom in the case of the failure of any party to maintain any
insurance coverage required to be maintained by such party pursuant to this
Lease. This provision is intended to waive fully, any rights and/or claims
arising by reason of the foregoing, but only to the extent that any of the
foregoing damages and/or claims referred to above are covered, and only to the
extent of such coverage, by insurance actually carried or required to be
maintained pursuant to this Lease by either Landlord or Tenant. This provision
is also intended to waive fully, and for the benefit of each party, any rights
and/or claims which might give rise to a right of subrogation on any insurance
carrier. Subject to all qualifications of this Paragraph 9, Landlord waives its
rights as specified in this Paragraph 9 with respect to any subtenant that it
has approved pursuant to Paragraph 21 but only in exchange for the written
waiver of such rights to be given by such subtenant to Landlord upon such
subtenant taking possession of the Premises or a portion thereof. Each party
shall cause each insurance policy obtained by it to provide that the insurance
company waives all right of recovery by way of subrogation against either party
in connection with any damage covered by any policy.

                    10.   LANDLORD'S REPAIRS AND MAINTENANCE

       Landlord shall at Landlord's expense maintain in good repair, reasonable
wear and tear excepted, the structural soundness of the roof, foundations, and
exterior walls of the Building. The term "exterior walls" as used herein shall
not include windows, glass or plate glass, doors, special store fronts or office
entries. Any damage clause by or repairs necessitated by any negligence or act
of Tenant or Tenant's Parties may be repaired by Landlord at Landlord's option
and Tenant's expense. Tenant shall immediately given Landlord written notice of
any defect or need of repairs in such components of the Building for which
Landlord is responsible, after which Landlord shall have reasonable opportunity
and the right to enter the Premises at all reasonable times to repair same.
Landlord's liability with respect to any defects, repairs or maintenance for
which Landlord is responsible under any of the provisions of this Lease shall be
limited to the cost of such repairs or maintenance, and there shall be no
abatement of rent and no liability of Landlord by reason of any injury to or
interference with Tenant's business arising from the making of repairs,
alterations or improvements in or to any portion of the Premises, the Building
or the Project or to fixtures, appurtenances or equipment in the Building,
except as provided in Paragraph 24. By taking possession of the Premises, Tenant
accepts them "as is," as being in good order, condition and repair and the
condition in which Landlord is obligated to deliver them and suitable for the
Permitted Use and Tenant's intended operations in the Premises, whether or not
any notice of acceptance is given.

                     11.   TENANT'S REPAIRS AND MAINTENANCE

       Tenant shall at all times during the Term at Tenant's expense maintain
all parts of the Premises and such portions of the Building as are within the
exclusive control of Tenant in a first-class, good, clean and secure condition
and promptly make all necessary repairs and replacements, as determined by
Landlord, with materials and workmanship of the same character, kind and quality
as the original. Notwithstanding anything to the contrary contained herein,
Tenant shall, at its expense, promptly repair any damage to the Premises or the
Building or Project resulting from or caused by any negligence or act of Tenant
or Tenant's Parties.

                               12.   ALTERATIONS

A.     Tenant shall not make, or allow to be made, any alterations, physical
additions, improvements or partitions, including without limitation the
attachment of any fixtures or equipment, in, about or to the Premises
("ALTERATIONS") without obtaining the prior written consent of Landlord, which
consent shall not be unreasonably withheld with respect to proposed Alterations
which: (a) comply with all applicable Regulations; (b) are, in Landlord's
opinion, comparable with the Building or the Project and its mechanical,
plumbing, electrical, heating/ventilation/air conditioning systems; and (c)
will not interfere with the use and occupancy of any other portion of the
Building or Project by any other tenant or it invitees. Specifically, but
without limiting the generality of the foregoing, Landlord shall have the right
of written consent for all plans and specifications for the proposed
Alterations, construction means and methods, all appropriate permits and
licenses, any contractor or subcontractor to be employed on the work of
Alterations, and the time for performance of such work, and may impose rules
and regulations for contractors and subcontractors performing such work. Tenant
shall also supply to

                                       7
<PAGE>   8
Landlord any documents and information reasonably requested by Landlord in
connection with Landlord's consideration of a request for approval hereunder.
Tenant shall cause all Alterations to be accomplished in a first-class, good and
workmanlike manner, and to comply with all applicable Regulations and Paragraph
27 hereof. Tenant shall at Tenant's sole expense, perform any additional work
required under applicable Regulations due to the Alternations hereunder. No
review or consent by Landlord of or to any proposed Alteration or additional
work shall constitute a waiver of Tenant's obligations under this Paragraph 12,
nor constitute any warranty or representation that the same complies with all
applicable Regulations, for which Tenant shall at all times be solely
responsible. Tenant shall reimburse Landlord for all costs which Landlord may
incur in connection with granting approval to Tenant for any such Alterations,
including any costs or expenses which Landlord may incur in electing to have
outside architects and engineers review said plans and specifications, and shall
pay Landlord an administration fee of fifteen percent (15%) of the cost of the
Alterations. All such Alterations shall remain the property of Tenant until the
expiration or earlier termination of this Lease, at which time they shall be and
become the property of Landlord; provided, however, that Landlord may, at
Landlord's option, require that Tenant, at Tenant's expense, remove any or all
Alterations made by Tenant and restore the Premises by the expiration or earlier
termination of this Lease, to their condition existing prior to the
construction of any such Alterations. All such removals and restoration shall
be accomplished in a first-class and good and workmanlike manner so as not to
cause any damage to the Premises or Project whatsoever. If Tenant fails to
remove such Alterations or Tenant's trade fixtures or furniture or other
personal property, Landlord may keep and use them or remove any of them and
cause them to be stored or sold in accordance with applicable law, at Tenant's
sole expense. In addition to and wholly apart from Tenant's obligation to pay
Tenant's Proportionate Share of Operating Expenses, Tenant shall be responsible
for and shall pay prior to delinquency any taxes or governmental service fees,
possessory interest taxes, fees or charges in lieu of any such taxes, capital
levies, or other charges imposed upon, levied with respect to or assessed
against its fixtures or personal property, on the value of Alterations within
the Premises, and on Tenant's interest pursuant to this Lease, or any increase
in any of the foregoing based on such Alterations. To the extent that any such
taxes are not separately assessed or billed to Tenant, Tenant shall pay the
amount thereof as invoiced to Tenant by Landlord.

B.  In compliance with Paragraph 27 hereof, at least ten (10) business 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.

                                   13.  SIGNS

     Tenant shall not place, install, affix, paint or maintain any signs,
notices, graphics or banners whatsoever or any window decor which is visible in
or from public view or corridors, the common areas or the exterior of the
Premises or the Building, in or on any exterior window or window fronting upon
any common areas or service area without Landlord's prior written approval
which Landlord shall have the right to withhold in its absolute and sole
discretion; provided that Tenant's name shall be included in any
Building-standard door and directory signage, if any, in accordance with
Landlord's Building signage program, including without limitation, payment by
Tenant of any fee charged by Landlord for maintaining such signage, which fee
shall constitute Additional Rent hereunder. Any installation of signs, notices,
graphics or banners on or about the Premises or Project approved by Landlord
shall be subject to any Regulations and to any other requirements imposed by
Landlord. Tenant shall remove all such signs or graphics by the expiration or
any earlier termination of this Lease. Such installations and removals shall be
made in such manner as to avoid injury to or defacement of the Premises,
Building or Project and any other improvements contained therein, and Tenant
shall repair any injury or defacement including without limitation
discoloration caused by such installation or removal.

                        14.  INSPECTION/POSTING NOTICES

     After reasonable notice, except in emergencies where no such notice shall
be required, Landlord and Landlord's agent and representatives, shall have the
right to enter the Premises to inspect the same, to clean, to perform such work
as may be permitted or required hereunder, to make repairs or alterations to
the Premises, Building or Project or to other tenant spaces therein, to deal
with emergencies, to post such notices as may be permitted or required by law
to prevent the perfection of liens against Landlord's interest in the Project
or to exhibit the Premises to prospective tenants, purchasers, encumbrancers or
to others, or for any other purpose as Landlord may deem necessary or
desirable; provided, however, that Landlord shall use reasonable efforts not to
unreasonably interfere with Tenant's business operations. Tenant shall not be
entitled to any abatements of Rent by reason of the exercise of any such right
of entry. At any time within six (6) months prior to the expiration of the Term
or following any earlier termination of this Lease or agreement to terminate
this Lease, Landlord shall have the right to erect on the Premises, Building
and/or Project a suitable sign indicating that the Premises are available for
lease.

                          15.  SERVICES AND UTILITIES

A.  Provided Tenant shall not be in default hereunder, and subject to the
provisions elsewhere herein contained and to the rules and regulations of the
Building, Landlord shall furnish to the Premises during ordinary business hours
of generally recognized business days, to be determined by Landlord (but
exclusive, in any event, of Saturdays, Sundays and legal holidays), water for
lavatory and drinking purposes and electricity, heat and air conditioning as
specified in the Basic Lease Information (as applicable) or as usually
furnished or supplied for use of the Premises for reasonable and normal office
use as of the date Tenant takes possession of the Premises as determined by
Landlord (but not including above-standard or continuous cooling for excessive
heat-generating machines, excess lighting or equipment), janitorial services
during the times and in the manner that such services are, in Landlord's
judgment, customarily furnished in comparable office buildings in the immediate
market area, and elevator service, which shall mean service either by
nonattended automatic elevators or elevators with attendants, or both, at the
option of Landlord. Tenant acknowledges that Tenant has inspected and accepts
the water, electricity, heat and air conditioning and other utilities and
services being supplied or furnished to the Premises as of the date Tenant
takes possession of the Premises, as being sufficient for use of the Premises
for reasonable and normal office use in their present condition, "as is," and
suitable for the Permitted Use, and for Tenant's intended operations in the
Premises. Landlord shall have no obligation to provide additional or
after-hours electricity, heating or air conditioning, but if Landlord elects to
provide such services at Tenant's request, Tenant shall pay to Landlord a
reasonable charge for such services as determined by Landlord. Tenant agrees to
keep and cause to be kept closed all window covering when necessary because of
the sun's position, and Tenant also agrees at all times to cooperate fully with
Landlord and to abide by all of the regulations and requirements which Landlord
may prescribe for the proper functioning and protection of electrical, heating,
ventilating and air conditioning systems. Wherever heat-generating machines,
excess lighting or equipment are used in the Premises which affect the
temperature otherwise maintained by the air conditioning system, Landlord
reserves the right to install supplementary air conditioning units in the
Premises and the cost thereof, including the cost of installation and the cost
of operation and maintenance thereof, shall be paid by Tenant to Landlord upon
demand by Landlord.

B.  Tenant shall not without written consent of Landlord use any apparatus,
equipment or device in the Premises, including without limitation, computers,
electronic data processing machines, copying machines, and other machines,
using excess lighting or using electric current, water, or any other resource
in excess of or which will in any way increase the amount of electricity,
water, or any other resource being furnished or supplied for the use of the
Premises, in each case as of the date Tenant takes possession of the Premises
as determined by Landlord, or which will require additions or alterations to or
interfere with the Building power distribution systems; nor connect with
electric current, except through existing electrical outlets in the Premises or
water pipes, any apparatus, equipment or device for the



                                       8

purpose of using electrical current, water, or any other resources. If Tenant
shall require water or electric current or any other resource in excess of that
being furnished or supplied for the use of the Premises as of the date Tenant
taken possession of the Premises as determined by Landlord, Tenant shall first
procure the written consent of Landlord which Landlord may refuse, to the use
thereof, and Landlord may cause a special meter to be installed in the Premises
so as to measure the amount of water, electric current or other resource
converted any such other use. Tenant shall pay directly to Landlord as an
addition to and separate from payment of Operating Expenses the cost of all such
additional resources, energy, utility service and meters (and of installation,
maintenance and repair thereof and of any additional circuits or other equipment
necessary to furnish such additional resources, energy, utility or service).
Landlord may add to the separate or metered charge a recovery of additional
expense incurred in keeping account of the excess water, electric current or
other resource so consumed. Landlord shall not be liable for any damages
directly or indirectly resulting from nor shall the Rent or any monies owed
Landlord under this Lease herein reserved be abated by reason of: (a) the
installation, use or interruption of use of any equipment used in connection
with the furnishing of any such utilities or services, or any change in the
character or means of supplying or providing any such utilities or services or
any supplier thereof; (b) the failure to furnish or delay in furnishing any such
utilities or services when such failure or delay is caused by acts of God or the
elements, labor disturbances of any character, or any other accidents or other
conditions beyond the reasonable control of Landlord because of any interruption
of service due to Tenant's use of water, electric current or other resource in
excess of that being supplied or furnished for the use of the Premises as of the
date Tenant takes possession of the Premises; (c) the inadequacy, limitation,
curtailment, rationing or restriction on use of water, electricity, gas or any
other form of energy or any other service or utility whatsoever serving the
Premises or Project, whether the Regulation or otherwise; or (d) the partial or
total unavailability of any such utilities or services to the Premises or the
Building, whether by Regulation or otherwise; nor shall any such occurrence
constitute an actual or constructive eviction of Tenant. Landlord shall further
have no obligation to protect or preserve any apparatus, equipment or device
installed by Tenant on the Premises, including without limitation by providing
additional or after-hours heating or air conditioning. Landlord shall be
entitled to cooperate voluntarily and in a reasonable manner with the efforts of
national, state or local governmental agencies or utility suppliers in reducing
energy or other resource consumption. The obligation to make services available
hereunder shall be subject to the limitations of any such voluntary, reasonable
program. In addition, Landlord reserves the right to change the supplier or
provider of any such utility or service from time to time. Tenant shall have no
right to contract with or otherwise any electrical or other such services for or
with respect to the Premises or Tenant's operations therein from any supplier or
provider of any such service. Tenant shall cooperate with Landlord and any
supplier or provider of such services designated by Landlord from time to time
to facilitate the delivery of such services to Tenant at the Premises and to
the Building and Project, including without limitation allowing Landlord and
Landlord's suppliers or providers, and their respective agents and contractors,
reasonable access to the Premises for the purpose of installing, maintaining,
repairing, replacing or upgrading such service or any equipment or machinery
associated therewith.

C.   Tenant shall pay, upon demand, for all utilities furnished to the Premises,
or if not separately billed to or metered to Tenant, Tenant's Proportionate
Share of all charges jointly serving the Project in accordance with Paragraph 7.
All sums payable under this Paragraph 15 shall constitute Additional Rent
hereunder.

                               16.  SUBORDINATION

     Without the necessity of any additional document being executed by Tenant
for the purpose of effecting a subordination, the Lease shall be and is hereby
declared to be subject and subordinate at all times to: (a) all ground leases or
underlying leases which may now exist or hereafter be executed affecting the
Premises and/or the land upon which the Premises and Project are situated, or
both; and (b) any mortgage or deed of trust which may now exist or be placed
upon the Building, the Project and/or the land upon which the Premises or the
Project are situated, or said ground leases or underlying leases, or Landlord's
interest or estate in any of said items which is specified as security.
Notwithstanding the foregoing, Landlord shall have the right to subordinate or
cause to be subordinated any such ground leases or underlying leases or any such
liens to this Lease. If any ground lease or underlying lease terminates for any
reason or any mortgage or deed of trust is foreclosed or a conveyance in lieu of
foreclosure is made for any reason, Tenant shall, notwithstanding any
subordination, attorn to and become the Tenant of the successor in interest to
Landlord provided that Tenant shall not be disturbed in its possession under
this Lease by such successor in interest so long as Tenant is not in default
under this Lease. Within ten (10) days after request by Landlord, Tenant shall
execute and deliver any additional documents evidencing Tenant's attornment or
the subordination of this Lease with respect to any such ground leases or
underlying leases or any such mortgage or deed of trust, in the form requested
by Landlord or by any ground landlord, mortgagee, or beneficiary under a deed of
trust, subject to such nondisturbance requirement. If requested in writing by
Tenant, Landlord shall use commercially reasonable efforts to obtain a
subordination, nondisturbance and attornment agreement for the benefit of Tenant
reflecting the foregoing from any ground landlord, mortgagee or beneficiary, at
Tenant's expense, subject to such other terms and conditions as the ground
landlord, mortgagee or beneficiary may require.

                           17.  FINANCIAL STATEMENTS

     At the request of Landlord from time to time, Tenant shall provide to
Landlord Tenant's and any guarantor's current financial statements or other
information discussing financial worth of Tenant and any guarantor, which
Landlord shall use solely for purposes of this Lease and in connection with the
ownership, management, financing and disposition of the Project.

                           18.  ESTOPPEL CERTIFICATE

     Tenant agrees from time to time, within ten (10) days after request of
Landlord, to deliver to Landlord, or Landlord's designee, an estoppel
certificate stating that this Lease is in full force and effect, that this Lease
has not been modified (or stating all modifications, written or oral, to this
Lease), the date to which Rent has been paid, the unexpired portion of this
Lease, that there are no current defaults by Landlord or Tenant under this Lease
(or specifying any such defaults); that the leasehold estate granted by this
Lease is the sole interest of Tenant in the Premises and/or the land at which
the Premises are situated, and such other matters pertaining to this Lease as
may be reasonably requested by Landlord. Failure by Tenant to execute and
deliver such certificate shall constitute an acceptance of the Premises and
acknowledgment by Tenant that the statements included are true and correct
without exception. Tenant agrees that if Tenant fails to execute and deliver
such certificate within such ten (10) day period, Landlord may execute and
deliver such certificate on Tenant's behalf and that such certificate shall be
binding on Tenant. Landlord and Tenant intend that any statement delivered
pursuant to this Paragraph may be relied upon any mortgagee, beneficiary,
purchaser or prospective purchaser of the Project or any interest therein. The
parties agree that Tenant's obligation to furnish such estoppel certificates in
a timely fashion is a material inducement for Landlord's execution of the Lease,
and shall be an event of default if Tenant fails to fully comply or makes any
material misstatement in any such certificate.

                             19.  SECURITY DEPOSIT

     Tenant agrees to deposit with Landlord upon execution of this Lease, a
security deposit as stated in the Basic Lease Information (the "Security
Deposit"), which sum shall be held and owned by Landlord, without obligation to
pay interest, as security for the performance of Tenant's covenants and
obligations under this Lease. The Security Deposit is not an advance rental
deposit or a measure of damages incurred by Landlord in case of Tenant's
default. Upon the occurrence of any event of default by Tenant, Landlord may
from time to time, without prejudice to any other remedy provided herein or by
law, use such fund as a credit to the extent necessary to credit against any
arrears of Rent or other payments due to Landlord hereunder, and any other
damage, injury, expenses or liability caused by such event of default, and
Tenant shall pay to Landlord, on demand, the amount so applied in order to
restore the Security Deposit to its original amount. Although the Security
Deposit shall be deemed the property of Landlord, any remaining balance of such
deposit shall be returned by


                                       9
<PAGE>   10
Landlord to Tenant at such time after termination of this Lease that all of
Tenant's obligations under this Lease have been fulfilled. Landlord may use and
commingle the Security Deposit with other funds of Landlord.

                             20.  TENANT'S REMEDIES

      The obligations and liability of Landlord to Tenant for any default by
Landlord under the terms of this Lease are not personal obligations of Landlord
or of the individual or other partners of Landlord or its or their partners,
directors, officers, or shareholders, and Tenant agrees to look solely to
Landlord's interest in the Project for the recovery of any amount from Landlord,
and shall not look to other assets of Landlord nor seek recourse against the
assets of the individual or other partners of Landlord or its or their partners,
directors, officers or shareholders. Any lien obtained to enforce any such
judgment and any levy of execution thereon shall be subject and subordinate to
any lien, mortgage or deed of trust on the Project. Under no circumstances shall
Tenant have the right to offset against or recoup Rent or other payments due and
to become due to Landlord hereunder except as expressly provided in Paragraph
23.8 below, which Rent and other payments shall be absolutely due and payable
hereunder in accordance with the terms hereof.

                         21.  ASSIGNMENT AND SUBLETTING

A.    (1)   GENERAL. This Lease has been negotiated to be and is granted as an
      accommodation to Tenant. Accordingly, this Lease is personal to Tenant,
      and Tenant's rights granted hereunder do not include the right to assign
      this Lease or sublease the Premises, or to receive any excess, either in
      installments or lump sum, over the Rent which is expressly reserved by
      Landlord as hereinafter provided, except as other wise expressly
      hereinafter provided. Tenant shall not assign or pledge this Lease or
      sublet the Premises or any part thereof, whether voluntarily or by
      operation of law, or permit the use or occupancy of the Premises or any
      part thereof by anyone other than Tenant, or suffer or permit any such
      assignment, pledge, subletting or occupancy, without Landlord's prior
      written consent except as provided herein. If Tenant desires to assign
      this Lease or sublet any or all of the Premises, Tenant shall give
      Landlord written notice (the "Transfer Notes") at least sixty (60) days
      prior to the anticipated effective date of the proposed assignment or
      sublease, which shall contain all of the information reasonably requested
      by Landlord to address Landlord's decision criteria specified
      hereinafter. Landlord shall then have a period of thirty (30) days
      following receipt of the Transfer Notice to notify Tenant in writing that
      Landlord elects either: (1) to terminate this Lease as to the space
      so affected as of the date so requested by Tenant; or (2) to consent to
      the proposed assignment or sublease, subject, however, to Landlord's
      prior written consent of the proposed assignee or subtenant and of any
      related documents or agreements associated with the assignment or
      sublease. If Landlord should fail to notify Tenant in writing of such
      election within said period, Landlord shall be deemed to have waived
      option (1) above, but written consent by Landlord of the proposed
      assignee or subtenant shall be required. If Landlord does not exercise
      option (1) above, Landlord's consent to a proposed assignment or sublet
      shall not be unreasonably withheld.

      (2)   CONDITIONS OF LANDLORD'S CONSENT. Without limiting the other
      instances in which it may be reasonable for Landlord to withhold
      Landlord's consent to an assignment or subletting, Landlord and Tenant
      acknowledge that it shall be responsible for Landlord to withhold
      Landlord's consent in the following instances: the use of the Premises by
      such proposed assignee or subtenant would not be a Permitted Use or would
      violate any exclusivity arrangement which Landlord has with any other
      tenant or occupant or would increase the Occupancy Density or Parking
      Density of the Building or Project; the proposed assignee or subtenant is
      not of sound financial condition as determined by Landlord in Landlord's
      sole discretion; the proposed assignee or subtenant is a governmental
      agency, the proposed assignee or subtenant does not have a good reputation
      as a tenant of property, the proposed assignee or subtenant is a person
      with whom Landlord is negotiating to lease space in the Project or is a
      present tenant of the Project; the assignment or subletting would entail
      any Alterations which would lessen the value of the leasehold improvements
      in the Premises, or Tenant is in default of any obligation of Tenant under
      this Lease, or Tenant has defaulted under this Lease on three (3) or more
      occasions during any twelve (12) months preceding the date that Tenant
      shall request consent. Failure by Landlord to consent to a proposed
      assignee or subtenant shall not cause a termination of this Lease. Upon a
      termination under Paragraph 21.A.(1), Landlord may lease the Premises to
      any party, including parties with whom Tenant has negotiated an assignment
      or sublease, without incurring any liability to Tenant. At the option of
      Landlord, a surrender and termination of this lease shall operate as an
      assignment to Landlord of some or all subleases or subtenancies. Landlord
      shall exercise this option by giving notice of that assignment to such
      subtenants on or before the effective date of the surrender and
      termination.

B.    BONUS RENT. Any Rent or other consideration realized by Tenant under any
such sublease or assignment in excess of the Rent payable hereunder, after
amortization of a reasonable brokerage commission incurred by Tenant, shall be
divided and paid, ten percent (10%) to Tenant, ninety percent (90%) to Landlord.
In any subletting or assignment undertaken by Tenant, Tenant shall diligently
seek to obtain the maximum rental amount available in the marketplace for
comparable space available for primary leasing.

C.    CORPORATION. If Tenant is a corporation, a transfer of corporate shares
by sale, assignment, bequest, inheritance, operation of law or other disposition
(including such a transfer to or by a receiver or trustee in federal or state
bankruptcy, insolvency or other proceedings) resulting in a change in the
present control of such corporation or any of its parent corporations by the
person or persons owning a majority of said corporate shares, shall constitute
an assignment for purposes of this Lease.

D.    UNINCORPORATED ENTITY.  If Tenant is a partnership, joint venture,
unincorporated limited liability company or other unincorporated business form,
a transfer of the interest of persons, firms or entities responsible for
managerial control of Tenant by sale, assignment, bequest, inheritance,
operation of law or other disposition, so as to result in a change in the
present control of said entity and/or a change in the identity of the persons
responsible for the general credit obligations of said entity shall constitute
an assignment for all purposes of this Lease.

E.    LIABILITY. No assignment or subletting by Tenant, permitted or otherwise,
shall relieve Tenant of any obligation under this Lease or alter the primary
liability of the Tenant named herein for the payment of Tent or for the
performance of any other obligations to be performed by Tenant, including
obligations contained in Paragraph 25 with respect to any assignee or
subtenant. Landlord may collect rent or other amounts or any portion thereof
from any assignee, subtenant, or other occupant of the Premises, permitted or
otherwise, and apply the net rent collected to the Rent payable hereunder, but
no such collection shall be deemed to be a waiver of this Paragraph 21, or the
acceptance of the assignee, subtenant or occupant as tenant, or a release of
Tenant from the further performance by Tenant of the obligations of Tenant
under this Lease. Any assignment or subletting which conflicts with the
provisions hereof shall be void.

                                 22.  AUTHORITY

      Landlord represents and warrants that is has full right and authority to
enter into this Lease and to perform all of Landlord's obligations hereunder
and that all persons signing this Lease on its behalf are authorized to do.
Tenant and the person or persons, if any, to preform all of Tenant's
obligations hereunder, and that all persons signing this Lease on its behalf
are authorized to do so.

<PAGE>   11

                               23.  CONDEMNATION

A.   CONDEMNATION RESULTING IN TERMINATION. If the whole or any substantial part
of the Project of which the Premises are a part should be taken or condemned for
any public use under governmental law, ordinance or regulation, or by right of
eminent domain, or by private purchase in lieu thereof, and the taking would
prevent or materially interfere with the Permitted Use of the Premises, this
Lease shall terminate and the Rent shall be abated during the unexpired portion
of this Lease, effective when the physical taking of said Premises shall have
occurred.

B.   CONDEMNATION NOT RESULTING IN TERMINATION. If a portion of the Project of
which the Premises are a part should be taken or condemned for any public use
under governmental law, ordinance or regulation, or by right of eminent domain,
or by private purchase in lieu thereof, and the taking prevents or materially
interferes with the Permitted Use of the Premises, and this Lease is not
terminated as provided in Paragraph 23.A, above, the Rent payable hereunder
during the unexpired portion of the Lease shall be reduced, beginning on the
date when the physical taking shall have occurred, to such amount as may be fair
and reasonable under all of the circumstances, but only after giving Landlord
credit for all sums received or to be received by Tenant by the condemning
authority.

C.   AWARD. Landlord shall be entitled to any and all payment, income, rent,
award or any interest therein whatsoever which may be paid or made in connection
with such taking or conveyance and Tenant shall have no claim against Landlord
or otherwise for the value of any unexpired portion of this Lease.
Notwithstanding the foregoing, any compensation specifically and separately
awarded Tenant for Tenant's personal property and moving costs, shall be and
remain the property of Tenant.

D.   WAIVER OF CCP SECTION 1265.130. Each party waives the provisions of
California Civil Code Procedure Section 1265.130 allowing either party to
petition the superior court to terminate this Lease as a result of a partial
taking.

                              24.  CASUALTY DAMAGE

A.   GENERAL. If the Premises or Building should be damaged or destroyed by
fire, tornado, or other casualty (collectively, "Casualty"), Tenant shall give
immediate written notice thereof to Landlord. Within thirty (30) days after
Landlord's receipt of such notice, Landlord shall notify Tenant whether in
Landlord's estimation material restoration of the Premises can reasonably be
made either: (1) within ninety (90) days; (2) in more than ninety (90) days but
within one hundred eighty (180) days; or (3) in more than one hundred eighty
(180) days, in each case from the date of such notice and receipt of required
permits for such restoration. Landlord's determination shall be binding on
Tenant.

B.   WITHIN 90 DAYS. If the Premises or Building should be damaged by Casualty
to such extent that material restoration can in Landlord's estimation be
reasonably completed within ninety (90) days after the date of such damage and
receipt of required permits for such restoration, this Lease shall not
terminate. Provided that insurance proceeds are received by Landlord to fully
repair the damage, Landlord shall proceed to rebuild and repair the Premises in
the manner determined by Landlord, except that Landlord shall not be required to
rebuild, repair or replace any part of the Alterations which may have been
placed on or about the Premises by Tenant. If the Premises are untenantable in
whole or in part following such damage, the Rent payable hereunder during the
period in which they are untenantable shall be abated proportionately, but only
to the extent of rental abatement insurance proceeds received by Landlord during
the time and to the extent the Premises are unfit for occupancy.

C.   GREATER THAN 90 DAYS. If the Premises or Building should be damaged by
Casualty to such extent that rebuilding or repairs can in Landlord's estimation
be reasonably completed in more than ninety (90) days but within one hundred
eighty (180) days after the date of such damage and receipt of required permits
for such rebuilding or repair, then Landlord shall have the option of either:
(1) terminating of this Lease effective upon the date of the occurrence of such
damage, in which event the Rent shall be abated during the unexpired portion of
this Lease; or (2) electing to rebuild or repair the Premises in the manner
determined by Landlord. Notwithstanding the above, Landlord shall not be
required to rebuild, repair or replace any part of any Alterations which may
have been placed on or about the Premises by Tenant. If the Premises are
untenantable in whole or in part following such damage, the Rent payable
hereunder during the period in which they are untenantable shall be abated
proportionately, but only to the extent of rental abatement insurance proceeds
received by Landlord during the time and to the extent the Premises are unfit
for occupancy. If Landlord should fail to complete such repairs and rebuilding
within one hundred eighty (180) days after the date upon which Landlord is
notified by Tenant of such damage and receipt of required permits, such period
of time to be extended for delays caused by the fault or neglect of Tenant or
otherwise by Tenant or because of acts of God, acts of public agencies, labor
disputes, strikes, fires, freight embargoes, rainy or stormy weather, inability
to obtain materials, supplies or fuels, or delays of the contractors or
subcontractors or any other causes or contingencies beyond the reasonable
control of Landlord, Tenant may at Tenant's option within ten (10) days after
the expiration of such one hundred eighty (180) day period (as such may be
extended), terminate this Lease by delivering written notice of termination to
Landlord as Tenant's exclusive remedy, whereupon this Lease shall terminate
thirty (30) days after Landlord's receipt of such termination notice.

D.   GREATER THAN 180 DAYS. If the Premises or Building should be so damaged by
Casualty that rebuilding or repairs cannot in Landlord's estimation be completed
one hundred eighty (180) days after such damage and receipt of required permits
for such rebuilding or repair, this Lease shall terminate and the Rent shall be
abated during the unexpired portion of this Lease, effective upon the date of
the occurrences of such damage.

E.   TENANT'S FAULT. Notwithstanding anything herein to the contrary, if the
Premises or any other portion of the Building are damaged by Casualty resulting
from the fault, negligence, or breach of this Lease by Tenant or any of Tenant's
Parties, Base Rent and Additional Rent shall not be diminished during the repair
of such damage and Tenant shall be liable to Landlord for the cost and expense
of the repair and restoration of the Building caused thereby to the extent such
cost and expense is not covered by insurance proceeds.

F.   INSURANCE PROCEEDS. Notwithstanding anything herein to the contrary, if the
Premises or Building are damaged or destroyed and are not fully covered by the
insurance proceeds received by Landlord or if the holder of any indebtedness
secured by a mortgage or deed of trust covering the Premises requires that the
insurance proceeds be applied to such indebtedness, then in either case Landlord
shall have the right to terminate this Lease by delivering written notice of
termination to Tenant within thirty (30) days after the date of notice to
Landlord that said damage or destruction is not fully covered by insurance or
such requirement is made by any such holder, as the case may be, whereupon this
Lease shall terminate.

G.   WAIVER. This Paragraph 24 shall be Tenant's sole and exclusive remedy in
the event of damage or destruction to the Premises or the Building. As a
material inducement to Landlord entering into this Lease, Tenant hereby waives
any rights it may have under Sections 1932, 1933(4), 1941 or 1942 of the Civil
Code of California with respect to any destruction of the Premises, Landlord's
obligation for tenantability of the Premises and Tenant's right to make repairs
and deduct the expenses of such repairs, or under any similar law, statute or
ordinance now or hereafter in effect.

H.   TENANT'S PERSONAL PROPERTY. In the event of any damage or destruction of
the Premises or the Building, under no circumstances shall Landlord be required
to repair any injury or damage to, or make any repairs to or replacements of,
Tenant's personal property.

<PAGE>   12
                                25. HOLDING OVER

     Unless Landlord expressly consents in writing to Tenant's holding over,
Tenant shall be unlawfully and illegally in possession of the Premises, whether
or not Landlord accepts any rent from Tenant or any other person while Tenant
remains in possession of the Premises without Landlord's written consent. If
Tenant shall retain possession of the Premises or any portion thereof without
Landlord's consent following the expiration of this Lease or sooner termination
for any reason, then Tenant shall pay to Landlord for each day of such
retention triple the amount of daily rental as of the last month prior to the
date of expiration or earlier termination. Tenant shall also indemnify, defend,
protect and hold Landlord harmless from any loss, liability or cost, including
consequential and incidental damages and reasonable attorneys' fees, incurred
by Landlord resulting from delay by Tenant in surrendering the Premises,
including, without limitation, any claims made by the succeeding tenant founded
on such delay. Acceptance of Rent by Landlord following expiration or earlier
termination of this Lease, or following demand by Landlord for possession of
the Premises, shall not constitute a renewal of this Lease, and nothing
contained in this Paragraph 25 shall waive Landlord's right of reentry or any
other right. Additionally, if upon expiration or earlier termination of this
Lease, or following demand by Landlord for possession of the Premises, Tenant
has not fulfilled its obligation with respect to repairs and cleanup of the
Premises or any other Tenant obligations as set forth in this Lease, then
Landlord shall have the right to perform any such obligations as it deems
necessary at Tenant's sole cost and expense, and any time required by Landlord
to complete such obligations shall be considered a period of holding over and
the terms of this Paragraph 25 shall apply. The provisions of this Paragraph 25
shall survive any expiration or earlier termination of this Lease.

                                  26. DEFAULT

A.   EVENTS OF DEFAULT. The occurrence of any of the following shall constitute
an event of default on the part of Tenant:

     (1)  ABANDONMENT. Abandonment or vacation of the Premises for a continuous
     period in excess of five (5) days. Tenant waives any right to notice
     Tenant may have under Section 1951.3 of the Civil Code of the State of
     California, the terms of this Paragraph 26.A. being deemed such notice to
     Tenant as required by said Section 1951.3.

     (2)  NONPAYMENT OF RENT. Failure to pay any installment of Rent or any
     other due and payable hereunder upon the date when said payment is due, as
     to which time is of the essence.

     (3)  OTHER OBLIGATIONS. Failure to perform any obligation, agreement or
     covenant under this Lease other than those matters specified in
     subparagraphs (1) and (2) of this Paragraph 26.A., such failure continuing
     for fifteen (15) days after written notice of such failure, as to which
     time is of the essence.

     (4)  GENERAL ASSIGNMENT. A general assignment by Tenant for the benefit of
     creditors.

     (5)  BANKRUPTCY. The filing of any voluntary petition in bankruptcy by
     Tenant, or the filing of an involuntary petition by Tenant's creditors,
     which involuntary petition remains undischarged for a period of thirty
     (30) days. If under applicable law, the trustee in bankruptcy or Tenant
     has the right to affirm this Lease and continue to perform the obligations
     of Tenant hereunder, such trustee or Tenant shall, in such time period as
     may be permitted by the bankruptcy court having jurisdiction, cure all
     defaults of Tenant hereunder outstanding as of the date of the affirmance
     of this Lease and provide to Landlord such adequate assurances as may be
     necessary to ensure Landlord of the continued performance of Tenant's
     obligations under this Lease.

     (6)  RECEIVERSHIP. The employment of a receiver to take possession of
     substantially all of Tenant's assets or Tenant's leasehold of the
     Premises, if such appointment remains undismissed or undischarged for a
     period of fifteen (15) days after the order therefor.

     (7)  ATTACHMENT. The attachment, execution or other judicial seizure of
     all or substantially all of Tenant's assets or Tenant's leasehold of the
     Premises, if such attachment or other seizure remains undismissed or
     undischarged for a period of fifteen (15) days after the levy thereof.

B.   REMEDIES UPON DEFAULT.

     (1)  TERMINATION. In the event of the occurrence of any event of default,
     Landlord shall have the right to give a written termination notice to
     Tenant, and on the date specified in such notice, Tenant's right to
     possession shall [???], and this Lease shall terminate unless on or
     before such date all Rent in arrears and all costs and expenses incurred
     by or on behalf of Landlord hereunder shall have been paid by Tenant and
     all other events of default of this Lease by Tenant at the time existing
     shall have been fully remedied to the satisfaction of Landlord. At any
     time after such termination, Landlord may recover possession of the
     Premises or any part thereof and expel and remove therefrom Tenant and any
     other person occupying the same, including any subtenant or subtenants
     notwithstanding Landlord's consent to any sublease, by any lawful means,
     and again repossess and enjoy the Premises without prejudice to any of the
     remedies that Landlord may have under this Lease, or at law or equity by
     any reason of Tenant's default or of such termination. Landlord hereby
     reserves the right, but shall not have the obligation, to recognize the
     continued possession of any subtenant. Landlord hereby reserves the
     right, but shall not have the obligation, to recognize the continued
     possession of any subtenant. The delivery or surrender to Landlord by or
     on behalf of Tenant of keys, entry codes, or other means to bypass
     security at the Premises shall not terminate this Lease.

     (2)  CONTINUATION AFTER DEFAULT. Even though an event of default may have
     occurred, this Lease shall continue in effect for so long as Landlord does
     not terminate Tenant's right to possession under Paragraph 26.B.(1)
     hereof, and Landlord may enforce all of Landlord's rights and remedies
     under this Lease and at law or in equity, including without limitation,
     the right to recover Rent as it becomes due, and Landlord, without
     terminating this Lease, may exercise all of the rights and remedies of a
     Landlord under Section 1951.4 of the Civil Code of the State of California
     or any successor code section. Acts of maintenance, preservation or
     efforts to lease the Premises or the appointment of a receiver under
     application of Landlord to protect Landlord's interest under this Lease or
     other entry by Landlord under the Premises shall not constitute an
     election to terminate Tenant's right to possession.

     (3)  INCREASED SECURITY DEPOSIT. If Tenant is in default under Paragraph
     26.A.(2) hereof and such default remains uncured for ten (10) days after
     such occurrence or such default occurs more than three times in any twelve
     (12) month period, Landlord may require that Tenant increase the Security
     Deposit to the amount of three times the current month's Rent at the time
     of the most recent default.

C.   DAMAGES AFTER DEFAULT. Should Landlord terminate this Lease pursuant to the
provisions of Paragraph 26.B.(1) hereof, Landlord shall have the rights and
remedies of a Landlord provided by Section 1951.2 of the Civil Code of the State
of California, or any successor code sections. Upon such termination, in
addition to any other rights and remedies to which Landlord may be entitled
under applicable law or at equity, Landlord shall be entitled to recover from
Tenant: (1) the worth at the time of award of the unpaid Rent and other amounts
which had been earned at the time of termination, (2) the worth at the time of
award of the amounts by which the unpaid Rent that would have been earned after
the date of termination until the time of award exceeds the amount of such Rent
loss that Tenant

                                       12
Version 10.1




<PAGE>   13
proves could have been reasonably avoided; (3) 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 the award exceeds the amount of such Rent loss that the Tenant proves
be reasonably avoided; and (4) any other amount and court costs necessary to
compensate Landlord for all detriment proximately caused by Tenant's failure to
perform Tenant's obligations under this Lease or which, in the ordinary course
of things, would be likely to result therefrom. The "worth at the time of award"
as used in (1) and (2) above shall be computed at the lesser of the "prime
rate," as announced from time to time by Wells Fargo Bank, N.A. (San Francisco)
or its successor, plus five (5) percentage points, or the maximum interest rate
allowed by law ("APPLICABLE INTEREST RATE"). The "worth at the time of award"
as used in (3) above shall be computed by discounting such amount at the Federal
Discount Rate of the Federal Reserve Bank of San Francisco at the time of the
award plus one percent (1%). If this Lease provides for any periods during the
Term during which Tenant is not required to pay Base Rent or if Tenant
otherwise receives a Rent concession, then upon the occurrence of an event of
default, Tenant shall owe to Landlord the full amount of such Base Rent or value
of such Rent concession, plus interest at the Applicable Interest Rate,
calculated from the date that such Base Rent or Rent concession would have been
payable.

D.   LATE CHARGE. In addition to its other remedies, Landlord shall have the
right without notice or demand to add to the amount of any payment required to
be made by Tenant hereunder, and which is not paid and received by Landlord on
or before the first day of each calendar month, an amount equal to ten percent
(10%) of the delinquency for each month or portion thereof that the delinquency
remains outstanding to compensate Landlord for the loss of the use of the amount
not paid and the administrative costs caused by the delinquency, the parties
agreeing that Landlord's damage by virtue of such delinquencies would be
extremely difficult and impracticable to compute and the amount stated herein
represents a reasonable estimate thereof. Any waiver by Landlord of any late
charges or failure to claim the same shall not constitute a waiver of other late
charges or any other remedies available to Landlord.

E.   INTEREST. Interest shall accrue on all sums not paid when due hereunder at
eighteen percent (18%) per annum from the due date until paid.

F.   REMEDIES CUMULATIVE. All rights, privileges and elections or remedies of
the parties are cumulative and not alternative, to the extent permitted by law
and except as otherwise provided herein.


                                   27. LIENS

     Tenant shall at all times keep the Premises and the Project free from
liens arising out of or related to work or services performed, materials or
supplies furnished or obligations incurred by or on behalf of Tenant or in
connection with work made, suffered or done by or on behalf of Tenant in or on
the Premises or Project. If Tenant shall not, within ten (10) days following
the imposition of any such lien, cause the same to be released of record by
payment or posting of a proper bond, Landlord shall have, in addition to all
other remedies provided herein and by law, the right, but not the obligation,
to cause the same to be released by such means as Landlord shall deem proper,
including payment of the claim giving rise to such lien. All sums paid by
Landlord on behalf of Tenant and all expenses incurred by Landlord in
connection therefor shall be payable to Landlord by Tenant on demand with
interest at the Applicable Interest Rate. Landlord shall have the right at all
times to post and keep posted on the Premises any notices permitted or required
by law, or which Landlord shall deem proper, for the protection of Landlord, the
Premises, the Project and any other party having an interest therein, from
mechanics' and materialmen's liens, and Tenant shall give Landlord not less
than ten (10) business days prior written notice of the commencement of any
work in the Premises or Project which could lawfully give rise to a claim for
mechanics' or materialmen's liens to permit Landlord to post and record a
timely notice of non-responsibility, as Landlord may elect to proceed or as the
law may from time to time provide, for which purpose, if Landlord shall so
determine, Landlord may enter the Premises. Tenant shall not remove any such
notice posted by Landlord without Landlord's consent, and in any event not
before completion of the work which could lawfully give rise to a claim for
mechanics' or materialmen's liens.


                                28. SUBSTITUTION

A.   At any time after the execution of this Lease, Landlord may substitute for
the Premises other premises in the Project or owned by Landlord in the vicinity
of the Project (the "NEW PREMISES") upon not less than sixty (60) days prior
written notice, in which event the New Premises shall be deemed to be the
Premises for all purposes hereunder and this Lease shall be deemed modified
accordingly to reflect the new location and shall remain in full force and
effect as so modified, provided that:

     (1)  The New Premises shall be similar in area and in function for
     Tenant's purposes; and

     (2)  If Tenant is occupying the Premises at the time of such substitution,
     Landlord shall pay the expense of physically moving tenant, Tenant's
     property and equipment to the New Premises and shall, at Landlord's sole
     cost, improve the New Premises with improvements substantially similar to
     those the Landlord has committed to provide or has provided in the
     Premises.


                           29. TRANSFERS BY LANDLORD

     In the event of a sale or conveyance by Landlord of the Building or a
foreclosure by any creditor of Landlord, the same shall operate to release
Landlord from any liability upon any of the covenants or conditions, express or
implied, herein contained in favor of Tenant, to the extent required to be
performed after the passing of title to Landlord's successor-in-interest. In
such event, Tenant agrees to look solely to the responsibility of the
successor-in-interest of Landlord under this Lease with respect to the
performance of the covenants and duties of "Landlord" to be performed after the
passing of title to Landlord's successor-in-interest. This Lease shall not be
affected by any such sale and Tenant agrees to attorn to the purchaser or
assignee. Landlord's successor(s)-in-interest shall not have liability to
Tenant with respect to the failure to perform any of the obligations of
"Landlord," to the extent required to be performed prior to the date such
successor(s)-in-interest became the owner of the Building.


              30. RIGHT OF LANDLORD TO PERFORM TENANT'S COVENANTS

     All covenants and agreements to be performed by Tenant under any of the
terms of this Lease shall be performed by Tenant at Tenant's sole cost and
expense and without any abatement of Rent. If Tenant shall fail to pay any sum
of money, other than Base Rent, required to be paid by Tenant hereunder or
shall fail to perform any other act on Tenant's part to be performed hereunder,
including Tenant's obligations under Paragraph 11 hereof, and such failure shall
continue for fifteen (15) days after notice thereof by Landlord, in addition to
the other rights and remedies of Landlord, Landlord may make any such payment
and perform any such act on Tenant's part. In the case of an emergency, no
prior notification by Landlord shall be required. Landlord may take such
actions without any obligation and without releasing Tenant from any of
Tenant's obligations. All sums so paid by Landlord and all incidental costs
incurred by Landlord and interest thereon at the Applicable Interest Rate, from
the date of payment by Landlord, shall be paid to Landlord on demand as
Additional Rent.



                                       13
<PAGE>   14
                                  31.  WAIVER

     If either Landlord or Tenant waives the performance of any term, covenant
or condition contained in this Lease, such waiver shall not be deemed to be a
waiver of any subsequent breach of the same or any other term, covenant or
condition contained herein, or constitute a course of dealing contrary to the
expressed terms of this Lease. The acceptance of Rent by Landlord shall not
constitute a waiver of any preceding breach by Tenant of any term, covenant or
condition of this Lease, regardless of Landlord's knowledge of such preceding
breach at the time Landlord accepted such Rent. Failure by Landlord to enforce
any of the terms, covenants or condition of this Lease for any length of time
shall not be deemed to waive or decrease the rights of Landlord to insist
thereafter upon strict performance by Tenant. Waiver by Landlord of any term,
covenant or condition contained in this Lease may only be made by a written
document signed by Landlord, based upon full knowledge of the circumstances.

                                  32.  NOTICES

     Each provision of this Lease or of any applicable governmental laws,
ordinances, regulations and other requirements with reference to sending,
mailing, or delivery of any notice or the making of any payment by Landlord or
Tenant to the other shall be deemed to be complied with when and if the
following steps are taken:

A.   RENT.  All Rent and other payments required to be made by Tenant to
Landlord hereunder shall be payable to Landlord at Landlord's Remittance
Address set forth in the Basic Lease information, or at such other address
as Landlord may specify from time to time by written notice delivered in
accordance herewith. Tenant's obligation to pay Rent and any other amounts to
Landlord under the terms of this Lease shall not be deemed satisfied until such
Rent and other amounts have been actually received by Landlord.

B.   OTHER.  All notices, demands, consents and approvals which may or are
required to be given by either party to the other hereunder shall be in writing
and either personally delivered, sent by commercial overnight courier, or
mailed, certified or registered, postage prepaid, and addressed to the party to
be notified at the Notice Address for such party as specified in the Basic
Lease information or to such other place as the party to be notified may from
time to time designate by at least fifteen (15) days notice to the notifying
party. Notices shall be deemed served upon receipt or refusal to accept
delivery. Tenant appoints as its agent to receive the service of all default
notices and notice of commencement of unlawful detainer proceedings the person
in charge of or apparently in charge of occupying the Premises at the time,
and, if there is not such person, then such service may be made by attaching
the name on the main entrance of the Premises.

C.   REQUIRED NOTICES.  Tenant shall immediately notify Landlord in writing of
any notice of violation or a potential or alleged violation of any Regulation
that relates to the Premises or the Project, or of any inquiry, investigation,
enforcement or other action that is instituted or threatened by any
governmental or regulatory agency against Tenant or any other occupant of the
Premises, or any claim that is instituted or threatened by any third party that
relates to the Premises or the Project.

                              33.  ATTORNEYS' FEES

     If Landlord places the enforcement of this Lease, or any part thereof, or
the collection of any Rent due, or to become due hereunder, or recovery of
possession of the Premises in the hands of an attorney, Tenant shall pay to
Landlord, upon demand, Landlord's reasonable attorneys' fees and court costs,
whether incurred without trial, at trial, appeal or review. In any action which
Landlord or Landlord brings to enforce its respective rights hereunder, the
unsuccessful party shall pay all costs incurred by the prevailing party
including reasonable attorneys' fees, to be fixed by the court, and said costs
and attorneys' fees shall be a part of the judgment in said action.

                          34.  SUCCESSORS AND ASSIGNS

     This Lease shall be binding upon and inure to the benefit of Landlord, its
successors and assigns, and shall be binding upon and insure to the benefit of
Tenant, its successors, and to the extent assignment is approved by Landlord as
provided hereunder, Tenant's assigns.

                               35.  FORCE MAJEURE

     If performance by a party of any portion of this Lease is made impossible
by any prevention, delay, or stoppage caused by strikes, lockouts, labor
disputes, acts of God, inability to obtain services, labor, or materials or
reasonable substitutions for those items, government actions, civil commotions,
fire or other casualty, or other causes beyond the reasonable control of the
party obligated to perform, performance by that party for a period equal to the
period of that prevention, delay, or stoppage is excused. Tenant's obligation to
pay Rent, however, is not excused by this Paragraph 35.

                           36.  SURRENDER OF PREMISES

     Tenant shall, upon expiration or sooner termination of this Lease,
surrender the Premises to Landlord in the same condition as existed on the date
Tenant originally took possession thereof, including, but not limited to, all
interior walls cleaned, all interior painted surfaces repainted in the original
color, all holes in walls repaired, all carpets shampooed and cleaned, and all
floors cleaned, waxed, and free of any Tenant-introduced marking or painting,
all to the reasonable satisfaction of Landlord. Tenant shall remove all of its
debris from the Project. At or before the time of surrender, Tenant shall comply
with the terms of Paragraph 12.A. hereof with respect to Alterations to the
Premises and all other matters addressed in such Paragraph. If the Premises are
not so surrendered at the expiration or sooner termination of this Lease, the
provisions of Paragraph 25 hereof shall apply. All keys to the Premises or any
part thereof shall be surrendered to Landlord upon expiration or sooner
termination of the Term. Tenant shall give written notice to Landlord at least
thirty (30) days prior to vacating the Premises and shall meet with Landlord for
a joint inspection of the Premises at the time of vacating. In the event of
Tenant's failure to give such notice or participate in such joint inspection,
Landlord's inspection at or after Tenant's vacating the Premises shall
conclusively be deemed correct for purposes of determining Tenant's
responsibility for repairs and restoration. Any delay caused by Tenant's failure
to carry out its obligations under this Paragraph 36 beyond the term hereof,
shall constitute unlawful and illegal possession of Premises under Paragraph 25
hereof.

                                  37.  PARKING

     So long as Tenant is occupying the Premises, Tenant and Tenant's Parties
shall have the right to use up the number of parking spaces specified in the
Basic Lease information on an unreserved, nonexclusive basis, for
passenger-size automobiles, in the parking areas in the Project designated from
time to time by Landlord for use in common by tenants of the Building.

     Tenant may request additional parking spaces from time to time and if
Landlord in its sole discretion agrees to make such additional spaces available
for use by Tenant, such spaces shall be provided on a month-to-month unreserved
and nonexclusive basis (unless otherwise agreed in writing by Landlord), and
subject to such parking charges as Landlord shall determine, and shall
otherwise be subject to such terms and conditions as Landlord may require.


                                       14
<PAGE>   15
     Tenant shall at all times comply and shall cause all Tenant's Parties and
visitors to comply with all Regulations and any rules and regulations
established from time to time by Landlord relating to parking at the Project,
including any keycard, sticker or other identification or entrance system, and
hours of operation, as applicable.

     Landlord shall have no liability for any damage to property or other items
located in the parking areas of the Project, nor for any personal injuries or
death arising out of the use of parking areas in the Project by Tenant or any
Tenant's Parties. Without limiting the foregoing, if Landlord arranges for the
parking areas to be operated by an independent contractor not affiliated with
Landlord, Tenant acknowledges the Landlord shall have no liability for claims
arising through acts or omissions of such independent contractor. In all events,
Tenant agrees to look first to its insurance carrier and to require that
Tenant's Parties look first to their respective insurance carriers for payment
of any losses sustained in connection with any use of the parking areas.

     Landlord reserves the right to assign specific spaces, and to reserve
spaces for visitors, small cars, disabled persons or for other tenants or
guests, and Tenant shall not park and shall not allow Tenant's Parties to park
in any such assigned or reserved spaces. Tenant may validate visitor parking by
such method as Landlord may approve, at the validation rate from time to time
generally applicable to visitor parking. Landlord also reserves the right to
alter, modify, relocate or close all or any portion of the parking areas in
order to make repairs or perform maintenance service, or to restripe or renovate
the parking areas, or if required by casualty, condemnation, act of God,
Regulations or for any other reason deemed reasonable by Landlord.

     Tenant shall pay to Landlord (or Landlord's parking contractor, if so
directed in writing by Landlord), as Additional Rent hereunder, the monthly
charges established from time to time by Landlord for parking in such parking
areas (which shall initially be the charge specified in the Basic Lease
Information, as applicable). Such parking charges shall be payable in advance
with Tenant's payment of Basic Rent. No deductions from the monthly parking
charge shall be made for days on which the Tenant does not use any of the
parking spaces entitled to be used by Tenant.

                               38.  MISCELLANEOUS

A.   GENERAL. The term "Tenant" or any pronoun used in place thereof shall
indicate and include the masculine or feminine, the singular or plural number,
individuals, firms or corporations, and their respective successors, executors,
administrators and permitted assigns, according to the context hereof.

B.   TIME. Time is of the essence regarding this Lease and all of its
provisions.

C.   CHOICE OF LAW. This Lease shall in all respects be governed by the laws of
the State of California.

D.   ENTIRE AGREEMENT. This Lease, together with its Exhibits, addenda and
attachments and the Basic Lease Information, contains all the agreements of the
parties hereto and supersedes any previous negotiations. There have been no
representations made by the Landlord or understandings made between the parties
other than those set forth in this Lease and its Exhibits, addenda and
attachments and the Basic Lease Information.

E.   MODIFICATION. This Lease may not be modified except by a written instrument
signed by the parties hereto. Tenant accepts the area of the Premises as
specified in the Basic Lease Information as the approximate area of the Premises
for all purposes under this Lease, and acknowledges and agrees that no other
definition of the area (rentable, usable or otherwise) of the Premises shall
apply. Tenant shall in no event be entitled to a recalculation of the square
footage of the Premises, rentable, usable or otherwise, and no recalculation, if
made, irrespective of its purpose, shall reduce Tenant's obligations under this
Lease in any manner, including without limitation the amount of Base Rent
payable by Tenant or Tenant's Proportionate Share of the Building and of the
Project.

F.   SEVERABILITY. If, for any reason whatsoever, any of the provisions hereof
shall be unenforceable or ineffective, all of the other provisions shall be and
remain in full force and effect.

G.   RECORDATION. Tenant shall not record this Lease or a short form memorandum
hereof.

H.   EXAMINATION OF 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.

I.   ACCORD AND SATISFACTION. No payment by Tenant of a lesser amount than the
total Rent due nor any endorsement on any check or letter accompanying any check
or payment of Rent shall be deemed an accord and satisfaction of full payment of
Rent, and Landlord may accept such payment without prejudice to Landlord's right
to recover the balance of such Rent or to pursue other remedies. All offers by
or on behalf of Tenant of accord and satisfaction are hereby rejected in
advance.

J.   EASEMENTS. Landlord may grant easements on the Project and dedicate for
public use portions of the Project without Tenant's consent; provided that no
such grant or dedication shall materially interfere with Tenant's Permitted Use
of the Premises. Upon Landlord's request, Tenant shall execute, acknowledge and
deliver to Landlord documents, instruments, maps and plots necessary to
effectuate Tenant's covenants hereunder.

K.   DRAFTING AND DETERMINATION PRESUMPTION. The parties acknowledge that this
Lease has been agreed to by both the parties, that both Landlord and Tenant have
consulted with attorneys with respect to the terms of this Lease and that no
presumption shall be created against Landlord because Landlord drafted this
Lease. Except as otherwise specifically set forth in this Lease, with respect to
any consent, determination or estimation of Landlord required or allowed in this
Lease or requested of Landlord, Landlord's consent, determination or estimation
shall be given or made solely by Landlord in Landlord's good faith opinion,
whether or not objectively reasonable. If Landlord fails to respond to any
requests for its consent within the time period, if any, specified in this
Lease, Landlord shall be deemed to have disapproved such request.

L.   EXHIBITS. The Basic Lease Information, and the Exhibits, addenda and
attachments attached hereto are hereby incorporated herein by this reference and

M.   NO LIGHT, AIR OR VIEW EASEMENT. Any diminution or shutting off of light,
air or view by any structure which may be erected on lands adjacent to or in the
vicinity of the Building shall in no way affect this Lease or impose any
liability on Landlord.

Tenant and nothing herein is intended to create any third party benefit.

observance and performance of all of the other covenants, terms and conditions
on Tenant's part to be observed and performed, Tenant shall peaceably and
quietly hold and enjoy the Premises for the term hereby described without
hindrance or interruption by Landlord or any other person or persons lawfully or
equitably



Version 10.1                           15

<PAGE>   16
claiming by, through or under Landlord, subject, nevertheless, to all of the
other terms and conditions of this Lease. Landlord shall not be liable for any
hindrance, interruption, interference or disturbance by other tenants or third
persons, nor shall Tenant be released from any obligations under this Lease
because of such hindrance, interruption, interference or disturbance.

P.     COUNTERPARTS. This Lease may be executed in any number of counterparts,
each of which shall be deemed an original.

Q.     MULTIPLE PARTIES. If more than one person or entity is named herein as
Tenant, such multiple parties shall have joint and several responsibility to
comply with the terms of this Lease.

R.     PRORATIONS. 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. As used herein, the term "fiscal year" shall mean the calendar year or
such other fiscal year as Landlord may deem appropriate.


                          39.   ADDITIONAL PROVISIONS

A.     RENT, RENT FOR THE PREMISES.

YEAR 1:     $16,846.70 per month, plus operating expenses per paragraph 7.B. of
            this Lease Agreement. Operating expenses through December, 1998 are
            estimated to be $5,147,45 per month. Direct operating expenses are
            estimated one year in advance and collected on a monthly basis. Any
            adjustments necessary (up or down) will be made at the end of the
            operating year.

YEAR 2:     $17,688.51 per month, plus operating expenses per Paragraph 7.B. of
            this Lease Agreement.

YEAR 3:     $18,530.82 per month, plus operating expenses per Paragraph 7.B. of
            this Lease Agreement.

YEAR 4:     $19,466.72 per month, plus operating expenses per Paragraph 7.B. of
            this Lease Agreement.

YEAR 5:     $20,496.21 per month, plus operating expenses per Paragraph 7.B. of
            this Lease Agreement.

B.     EARLY OCCUPANCY. Upon full execution of this Lease Agreement, Tenant
shall commit to occupy the Premises on January 14, 1998 or upon substantial
completion of Tenant Improvements, whichever occurs first, with all terms and
conditions of this Lease in full force and effect, including the payment of
rent and operating expenses, which shall be prorated from the date of occupancy.

C.     LETTER OF CREDIT. Tenant shall pay to Landlord Tenant's security deposit
for the faithful performance of all terms, covenants and conditions of this
Lease. The amount of security deposit required is specified on the Basic Lease
Information sheet of the Lease and this Paragraph 39.C.

Tenant shall provide Landlord with an irrevocable standby letter of credit from
Silicon Valley Bank each in the amount of One Hundred Thousand and no/100ths
U.S. Dollars ($100,000.00). Tenant shall deliver to Landlord the first one-year
letter of credit upon execution of Lease. Said letter of credit shall be
renewed annually for five (5) consecutive years to expire on January 31, 2003.
The term "security deposit" as used herein shall mean, as applicable, such
letter of credit or cash deposit.

Tenant agrees that Landlord may, without waiving any of Landlord's other rights
and remedies under this Lease upon the occurrence of any of the events of
default described in this Lease (and following the expiration or any applicable
notice and cure periods), apply or draw down the security in whole or in part
to remedy any failure to pay any amounts owing to Landlord herein, to repair or
maintain the premises or to perform any other terms, covenants or conditions
contained herein. Additionally, in the event that Tenant fails to replace any
letter of credit delivered pursuant to this Addendum at least sixty (60) days
prior to the expiration of such letter of credit with a new letter of credit
acceptable to Landlord, Landlord shall have the right to draw down the letter
of credit in whole or in part, in which event all amounts so drawn, to the
extent not applied to cure an event of default as provided in the Lease, shall
be held by Landlord as if Tenant had deposited a cash security deposit.

Without limiting the generality of the foregoing, in the event that this Lease
is terminated and such termination does not coincide with the expiration of a
Basic Operating Cost fiscal year, as applicable, Landlord may retain the
security deposit for a reasonable period of time after the expiration of the
Basic Operating Cost fiscal year, in order to allow Landlord the opportunity to
determine the actual amount of Tenant's Proportionate Share of actual Basic
Operating Cost and to deduct any amount due from Tenant relating thereon as
applicable. Should Landlord use or draw down any portion of the security
deposit to cure any default by Tenant herein. Tenant shall forthwith replenish
the security deposit to the original amounts. Landlord shall not be required to
keep any security deposit in the form of cash separate from its general funds
and Tenant shall not be entitled to interest on any such cash deposit.

Landlord agrees to deduct the amount of the letter of credit to zero on
February 1, 1999, provided the following conditions are met for the reduction:

    -  Tenant is not or has not been in default of any of the terms and
       conditions of this Lease.

    -  Landlord is provided with a copy of Tenant's financial statement showing
       that Tenant's business is profitable.

Should the preceding conditions not be met, the letter of credit shall be
renewed in the amount of One Hundred Thousand and no/100ths U.S. Dollars
($100,000.00) for one (1) year on such anniversary of the Lease Commencement
date and shall not be reduced until the conditions hereunder have been met
completely.

All other terms and conditions of the Lease Agreement shall remain in full

    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

    concerning the admission to, or exclusion from, the Building or the Project
