                                    --------

      2.01 The Premises. The premises demised and leased hereunder (the
           -------------                                                
"Premises") are shown on the Floor Plan attached hereto as Exhibit "A" and
incorporated herein by this reference. The Premises consist of office space
situated in that certain Property and improvements shown on the "Site Plan"
attached hereto and incorporated herein as Exhibit "B".

      2.02 Rentable Area. The rentable area set forth in the Fundamental Lease
           --------------                                                     
Provisions (the "Rentable Area") is subject to verification by the Landlord's
architect, whose determination of the verified Rentable Area shall be conclusive
and binding on the parties. In the event that the Landlord's project architect
shall determine that the verified Rentable Area is more or less than the
Rentable Area set forth in the Fundamental Lease Provisions, then the Basic
Annual Rent shall be adjusted to the sum which is the result of multiplying the
Basic Annual Rent by a fraction, the numerator of which is the verified
Rentable Area, and the denominator of which is the Rentable Area set forth in
the Fundamental Lease Provisions; in such event, the adjustment shall be
confirmed in writing by the parties pursuant to Exhibit "C" to this Lease,
executed upon request of either party.

      2.03 Tenant's Rights to Use in Common. Tenant shall have, as appurtenant
           ---------------------------------                                  
to the Premises, rights to use in common, subject to reasonable rules of general
applicability to tenants of the Property from time to time made by Landlord and
of which Tenant is given notice, the following areas of the Property: the common
lobbies, corridors, stairways and stairwells, restrooms, elevators, and common
walkways and driveways necessary for access to the Property (the "Common Area").
Tenant hereby agrees that Landlord shall have the right, for the purposes of
accommodating the other tenants of the Property, to increase or decrease the
configuration and dimensions or to otherwise alter the common corridors on any
floor so long as Tenant's access to the Premises, fire exits, restrooms,
stairwells and elevators is not unreasonably prohibited thereby.



                                   ARTICLE III
                                      TERM
                                      ----

      3.01 Commencement of Term and Duration. Tenant shall have and hold the
           ----------------------------------                               
Premises for a period (herein referred to as the "Term") commencing on the date
(the "Commencement Date") which shall be the earlier of (i) the date on which
the Premises are "Ready for Occupancy" as defined in Section 3.02 below, or (ii)
the date on which Tenant takes possession or commences use of the Premises for
any purpose, and continuing for the term set forth in the Fundamental Lease
Provisions, unless sooner terminated as provided in this Lease. The Commencement
Date shall be confirmed in writing as set forth in Section 3.05 hereof, (See
attached Exhibit "C" hereto)

      3.02 Delivery of Premises. The parties anticipate that the Premises shall
           ---------------------                                               
be Ready for Occupancy within thirty (30) days of the scheduled term
commencement date set forth in the Fundamental Lease Provisions. In the event
that it becomes apparent to Landlord that the Premises shall not be Ready for
occupancy within ten (10) days of the scheduled term commencement date, Landlord
shall use reasonable efforts to advise Tenant of the anticipated date that the
Premises will be ready for occupancy at least ten (10) days prior to such date,
but the failure to give such notice shall not constitute a default hereunder by
Landlord. Tenant agrees that in the event of the inability of Landlord to
deliver possession of the Premises to Tenant by the scheduled term commencement
date, this Lease shall not be void or voidable, nor shall Landlord be liable to
Tenant for any loss or damage resulting therefrom, but in such event Tenant
shall not be liable for any rent until the Premises are ready for occupancy. Any
failure to deliver possession at the scheduled term commencement date, shall not
affect the obligations of Tenant hereunder, except that if Landlord has failed
to deliver possession of the Premises to Tenant within six (6) months after the
scheduled term commencement date, Landlord or Tenant may, at either option, by
notice in writing to the other party within thirty (30) days thereafter, cancel
this Lease, in which event the parties shall be discharged from all obligations
hereunder.

      3.03 Early Entry Into Premises. Tenant may enter into the Premises upon
           --------------------------                                        
receipt of Landlord's consent, for the purpose of installing furniture, special
flooring or carpeting, trade fixtures, telephones, computer, photocopy
equipment, and other business equipment. Such early entry will not advance the
Commencement Date, providing (i) Tenant does not commence business operations
from any part of the Premises, and (ii) Tenant's early entry does not interfere
with, or delay, the completion of time Tenant Improvements. If Tenant is allowed
early entry, Landlord shall not be responsible for, and the Tenant is required
to obtain insurance covering, any loss, including theft, damage or destruction
to any work or material installed or stored by Tenant or Landlord, or any
contractor or individual involved in the completion of the Tenant Improvements
at the Premises, or for any injury to Tenant or Tenant's employees or to any
person. Landlord shall have the right to post the appropriate notices of
non-responsibility and 

                                       3
<PAGE>
 
to require Tenant to provide Landlord with evidence that Tenant has fulfilled
its obligation to provide insurance pursuant to Article XIII of this Lease. To
the actual extent any such entry actually delays the Commencement Date such
delay, but only to the extent that such early entry actually delays the
completion of the Tenant Improvements, shall constitute a delay caused by
Tenant.

      3.04 Effective Date. This Lease will become effective when signed by the
           ---------------                                                    
Landlord and Tenant and delivered to Tenant. Subject to the respective
obligations of Landlord and Tenant regarding the construction of Tenant
Improvements, if any, as hereinafter set forth, the Tenant accepts the Premises
in its "as is" condition as of the date this Lease is signed by Tenant. Tenant
acknowledges that it has inspected or has waived inspection of the Premises and
the Property prior to the time this Lease was executed by Tenant.

      3.05 Acceptance of Premises. It is expressly understood by the parties
           -----------------------                                          
that "Ready for Occupancy" does not include the installation and completion of a
telephone system in the Premises, which shall be solely Tenant's responsibility.
Promptly following the delivery of said Landlord's certificate to Tenant by
Landlord, Tenant shall countersign and return to Landlord an "Acceptance and
Statement of Premises, Area and Term" which will be sent by Landlord to Tenant,
and which will be in the form of a letter attached hereto as Exhibit "C",
Tenant's signature of said letter shall be Tenant's agreement of the
Commencement Date and termination date of this Lease and Tenant's acceptance of
the Premises in its "as is" condition ("punch list items" excepted), Tenant
thereby agreeing that Landlord has fulfilled its obligations pursuant to Exhibit
"C" of this Lease.  The failure by Tenant to sign and return the "Acceptance and
Statement of Premises, Area and Term (the "Statement")" to Landlord within ten
(10) days of Tenant's receipt of same shall be deemed to constitute (i) Tenant's
acceptance of the Premises; (ii) Tenant's acknowledgment of the Commencement
Date as specified in the Statement; (iii) Tenant's acknowledgment of the
termination date as specified in the Statement; (iv) Tenant's acknowledgment of
the Rentable Area of the Premises as specified in the Statement; (v) Tenant's
acknowledgment of the Basic Annual Rent and monthly installments thereof as
specified in the Statement; and (vi) Tenant's Proportionate Share as specified
in the Statement.


                                   ARTICLE IV
                                      RENT
                                      ----

      4.01 Basic Rent. Throughout the Term of this Lease, Tenant shall pay as
           -----------                                                         
rent for the Premises the Basic Annual Rent (sometimes referred to as "Base
Rent" or "Rent") set forth in the Fundamental Lease Provisions thereof, as such,
basic Annual Rent may be adjusted as hereinafter provided. Basic Rent shall be
payable in equal monthly installments in advance on the first day of each, and
every calendar month, in full, without deduction, abatement or off-set, and
without prior demand or notice. The monthly payment for the first month, after
the Commencement Date is made concurrently with the execution hereof. If the
Commencement Date is other than the first day of a calendar month, then the rent
payable hereunder shall be prorated on a daily basis, based on a three hundred
sixty (360) day year, and the rent for such partial month following the
Commencement Date shall be payable on the Commencement Date.

      4.02 Additional Rent for Increase in Cost of Operation and Maintenance.
           ------------------------------------------------------------------
Basic Rent shall be increased, and Tenant shall pay Tenant's Proportionate Share

Operation and Maintenance of the Property during the term of this Lease in
accordance with the following provision:

      A. If the Property is not fully constructed and completed and/or does not
have at least ninety five percent (95%) of the rentable area of the Property

and Maintenance, which would have been incurred by Landlord if the Property had
been fully constructed and completed and ninety five percent (95%) of the
rentable area of the Property had been occupied for the entirety of such
calendar year. However, in no event shall there be included in such computation
taxes which are never assessed or which Landlord does not have to pay. Annual
amortization of costs shall be determined by dividing the original cost of such
capital expenditure by the number of years of useful life of the capital item
acquired, or by the number of years permitted by the IRS for amortization,
whichever is shorter. Taxes and Cost of Operation and Maintenance shall be
computed according to the cash or accrual basis of accounting, as Landlord may
elect in accordance with standard and reasonable accounting principles employed
by Landlord.

      B. Costs of Operation and Maintenance. The term "Costs of Operation and
         -----------------------------------                                 
Maintenance" shall be defined as those expenses incurred by Landlord with
respect to the repair, alteration, improvement, replacement, operation and
maintenance of the Premises, Property and Parking Facilities, in accordance
with accepted principles of sound accounting practice and industry standards as
applied to the operation, maintenance and security of a first-class office
building, which costs shall include but not limited to the following:

Property was constructed;

          10) The annual amortization of costs, including financing costs

          12) All insurance expenses which shall mean all premiums and other
charges incurred by Landlord with respect to the insurance of the Property
including, without limitation, the following to the extent carried by the
Landlord: (a) fire and extended coverage insurance, windstorm, hail and
explosion; (b) riot attending a strike, civil commotion, aircraft, vehicle and

           5) any and all assessment, tax, fees, levies or charges allocable to
or measured by the area of the Property and Parking Facilities or the rent
payable hereunder, including without limitation, any gross income tax or excise
tax levied by the city, county, state or federal government or any political
subdivision thereof, with respect to the receipt of such rent, or upon or with
respect to the possession, operation, management, maintenance, alteration,
repair, use or occupancy by Tenant of the Property, or any portion thereof.
Property Taxes shall not include Landlord's federal or state income, franchise,
inheritance or estate taxes.

      D. Landlord shall have the right in its discretion to contest the amount
or validity of any Property Taxes by appropriate legal proceedings and to
include in the costs of Operation and Maintenance of the Property the reasonable
cost of any such contest, including attorneys' fees. If, in any comparison year
subsequent to the Base Year (the "Adjustment Year"), the amount of Tax Expenses
decrease as a result of the efforts of Landlord, then for purposes of all
subsequent comparison years, including the comparison year in which such
decrease in Tax Expenses occurred, the Tax Expenses deemed attributable to the
Base Year shall be decreased by an amount equal to the decrease in Tax Expenses
in the Adjustable Year.

      E. Tenant's Proportionate Share/Rentable Square Footage of the Property.
         ---------------------------------------------------------------------
As used herein, the term "Tenant's Proportionate Share" shall mean the
proportion of the rentable area of the Premises to the rentable area of the
Property. The rentable area of the Property, for the purpose of calculating the
adjustment to the Basic Rent pursuant to this Article IV, shall be computed by
measuring from the inside surface of the glass outer walls of the Property. Such
rentable area encompasses all area within the outer walls of the Property
(including, without limitation, all janitor, mechanical and electrical closets,
code required Handicapped Refuge Areas, and rooms, restrooms, corridors, and
elevator lobbies), and excludes only the Parking Facilities within the Property
(if any), public stairs controlled by Landlord and shafts for public elevators.
No deductions are made for columns and projections within the outer walls of the
Property necessary to the Property.

      F. Expense/Tax Base Year. As used in this Article IV, "Base Year" for
         ----------------------                                            
purpose of determining additional rent payable by reason of increases in taxes,
shall mean the fiscal year as set forth in section 1.02(D) of the Fundamental
Lease Provisions. For the purposes of determining additional rent payable by
reason of increases in Cost of Operation and Maintenance, "Base Year" shall mean
the calendar year as set forth in Section 1.02(D) of the Fundamental Lease
Provisions.

      G. Procedure for Payment of Taxes and Operation Expenses. Tenant shall pay
         ------------------------------------------------------                 
for Tenant's Proportionate Share of the Taxes and Costs for Operation and
Maintenance of the Property, Premises and Parking Facilities for each calendar
year occurring during the term hereof which shall be determined by Landlord on a
yearly basis. Subsequent to such determination, landlord shall notify Tenant in
writing of tenant's Proportionate Share of the Taxes and Costs of Operation and
Maintenance of the Property, Premises and Parking Facilities for the calendar
year just ended. In the event rent is to be increased, the following procedure
shall be followed:

           1) Landlord may, from time to time by ten (10) days written notice to
Tenant, reasonable estimate in advance the amounts Tenant shall owe on a monthly
basis for Taxes and Cost of Operation and Maintenance for any full or partial
calendar year of the Term. In such event, Tenant shall pay such estimated
amounts, on a monthly basis, on or before the first day of each calendar month,
together with Tenant's payment of Base Rent. Such estimate may be reasonably
adjusted from time to time by Landlord by notice to Tenant.

                                       6
<PAGE>
 
           2) Within one hundred twenty (120) days after the end of each
calendar year, or as soon thereafter as practicable, Landlord shall provide a
statement (the "Statement") to Tenant showing: (i) the amount of actual Taxes
and Cost of Operation and Maintenance for such calendar year, with a listing of
amounts for major categories of Cost of Operation and Maintenance, (ii) any
amount paid by Tenant towards Taxes and Cost of Operation and Maintenance during
such calendar year on an estimated basis, and (iii) any revised estimate of
Tenant's obligations for Taxes and Cost of Operation and Maintenance for the
current calendar year.

           3) If the Statement shows that Tenant's estimated payments were less
than Tenant's actual obligations for Taxes and Cost of Operation and Maintenance
for such year, Tenant shall pay the difference. If the statement shows an
increase in Tenant's estimated payments for the current calendar year, Tenant
shall pay the difference between the new and former estimates, for the period
from January 1 of the current calendar year through the month in which the
Statement is sent. Tenant shall make such payments with the next Basic Rent
Payment due.

           4) If the Statement shows that Tenant's estimated payments exceeded
Tenant's actual obligations for Taxes and Cost of Operation and Maintenance,
Tenant shall receive a credit for the difference, against future payments of
Taxes or Cost of Operation and Maintenance next due. If the Term shall have
expired, Tenant shall receive a refund of such difference, within thirty (30)
days after Landlord sends the Statement.

           5) If the Statement shows an increased Escalation Amount, Tenant
shall pay the difference between the former Escalation Amount and the increased
Escalation Amount for the period from January 1 of the year in which Landlord
sends the Statement, through the month in which the Statement is sent, with the
next Basic Rent Payment due. Tenant shall thereafter pay Base Rent, as increased
by the Escalation Amount set forth in the Statement.

           6) So long as Tenant's obligations hereunder are not materially
adversely affected, Landlord reserves the right to reasonably change, from time
to time, the manner or timing of the foregoing payments. In lieu of providing
one Statement covering Taxes and Cost of Operation and Maintenance, Landlord may
provide separate statements, at the same or different times. No delay by
landlord in providing the Statement (or separate statements) shall be deemed a
default by Landlord or a waiver of Landlord's right to require payment of
Tenant's obligations for actual or estimated Taxes or Cost of Operation and
Maintenance.

           7) If the Term commences other than on January 1, or ends other than
December 31, Tenant's obligations to pay estimated and actual amounts towards
Taxes and Cost of Operation and Maintenance for such first or final calendar
years shall be prorated to reflect the portion of such years included in the
Term. Such proration shall be made by multiplying the total estimated or actual
(as the case may be) Taxes and Cost of Operation and Maintenance, for such
calendar year, by a fraction, the numerator of which shall be the number of days
of the Term during such calendar year, and the denominator of which shall be
three hundred sixty (360).

      H. Payment at End of Term. In the event that, after the end of the term of
         -----------------------                                                
this Lease, or the sooner termination thereof, Tenant shall have as Basic Rent
an amount greater than that calculated to have been due pursuant to this Section
4.02 for the calendar year in which the term of this Lease terminates, Landlord
shall refund the overpayment to Tenant within ninety (90) days from the date of
said termination. In the event that, after the end of the term of this Lease, or
the sooner termination thereof, Tenant shall have theretofore paid as Basic Rent
an amount less than that calculated to have been due pursuant to this Section
4.02 for the calendar year in which the term of this Lease terminates, Tenant
agrees to pay to Landlord, within thirty (30) days of Tenant's receipt of
Landlord's bill, that amount calculated as actually owed by Tenant to Landlord
pursuant to this Section 4.02.

                                       7

      4.04 Personal Property Taxes and Business Taxes. Tenant shall pay in full
           -------------------------------------------                         
and in a timely manner all taxes levied against the personal property of Tenant,
and Landlord shall have no liability therefor. If the Tenant's improvements in
the Premises, whether installed and/or paid for by Landlord or Tenant and
whether or not affixed to the real property so as to become a part thereof, are
assessed for real property tax purposes at a valuation higher than the valuation
at which Tenant Improvements conforming to Landlord's standard building
materials in other space in the Property are assessed, then the real property
taxes and assessments levied against Landlord or the Property by reason of such
excess assessed valuation shall be deemed to be taxes levied against personal
property of Tenant and the payment thereof shall be governed by the provisions
of this Article IV. If the records of the County Assessor are available and
sufficiently detailed to serve as a basis for determining whether said Tenant
Improvements are assessed at a higher valuation than Landlord's Building
Standard, such records shall be binding on both the Landlord and the Tenant. If
the records of the County Assessor are not available or sufficiently detailed to
serve as a basis for making such determination the actual retail cost of
construction and materials shall be used.

      4.05 Special Charges for Special Services and Special Insurance. Tenant
           -----------------------------------------------------------       
agrees to pay to Landlord, within ten (10) days following written demand, all
reasonable charges for any services, utilities, goods or materials including
additional security, special repairs or any other such costs not otherwise
provided herein to be furnished by Landlord at Tenant's request which are not
required to be furnished by Landlord under this Lease without separate charge or
assessment, plus an administration fee of not less than fifteen percent (15%).

      4.06 Tenant's Payment of Additional Rent. Except as otherwise specifically
           ------------------------------------                                 
provided herein, any sum, amount, item or charge designated or considered as
additional rent in this Lease or any other sum, amount, item or charge payable
by Tenant to Landlord pursuant to this Lease shall be paid by Tenant to Landlord
on the first day of the month following the date on which Landlord notifies
Tenant of the amount payable or on the fifth day after the giving of such
notice, whichever shall be later. Any such notice shall specify in reasonable
detail the basis of such additional rent. Additional rent shall be paid by
Tenant to Landlord without off-set, deduction, abatement or credit.

      4.07 Review of Taxes and Cost of Operation and Maintenance. Tenant shall
           ------------------------------------------------------             
have a period of six (6) months following receipt of the Statement, within which
to inspect, at Landlord's office during normal business hours, Landlord's books
and records concerning Taxes and Cost of Operation and Maintenance for the
preceding calendar year in question. Such inspection may only be done by an
accounting firm which is generally considered to be a nationally recognized
firm. If Tenant shall not have availed itself of such inspection, Tenant shall
be deemed to have accepted as final and determinative the amounts shown on the
Statement. If Tenant shall have exercised its right to inspect the books and
records, and then disputes the accuracy of the information set forth in
Landlord's books and records with respect to the Statement, Tenant shall
nevertheless continue to pay the amounts as required by the provisions of
Sections 4.02 through 4.06. If Landlord and Tenant shall not mutually agree on
the Taxes and Cost of Operation and Maintenance charged to Tenant, no later than
one (1) year after receipt of the Statement, Tenant must (or its right to
contest such charges shall be deemed waived) institute arbitration proceedings,
against Landlord in an Arbitration proceeding governed by the rules of the
American Arbitration Association to collect and recover any overpayments made by
Tenant resulting from the errors in the books and records of Landlord; and
provided further, that Tenant shall within ten (10) days of filing the complaint
serve Landlord with a copy of the complaint filed in any such proceeding. Each
party shall bear its own costs and expenses including, but not limited to
attorneys' fees, arbitration costs, accounting costs, and any other fees
incurred as a result of such review.

      If Tenant institutes such Arbitration procedures, then the Arbitrator
shall have the power to, and shall, inquire into and determine not only whether
or not the Tenant was overcharged for such Taxes and Cost of Operation and
Maintenance, but whether or not the Tenant was undercharged for such Taxes and
Cost of Operation and Maintenance. At the conclusion of the Arbitration, the
Arbitrator shall issue a ruling as to what the Taxes and Cost of Operation and
Maintenance should have been had the Landlord strictly complied with the
provisions of this Lease. If the Landlord overcharged the Tenant for Taxes and
Cost of Operation and Maintenance, the amount of the overcharge shall be applied
to future payments of Taxes and Cost of Operation and Maintenance next due
following the conclusion of the Arbitration. If the Arbitrator determines that
the Tenant was undercharged for Taxes and Cost of Operation and Maintenance,
Tenant shall pay the amount of such undercharge to the Landlord within thirty
(30) days following the issuance of the Arbitration Ruling.

      4.08 Late Charges. Tenant hereby acknowledges that late payment by Tenant
           -------------                                                       
to Landlord of rent and other sums due hereunder will cause Landlord to incur
costs not contemplated by this Lease, the exact amount of which will be
extremely difficult to ascertain. Such costs include, but are not limited to,
processing and accounting charges and late charges which may be imposed on
Landlord by the terms of any trust deed covering the Property. Accordingly, if
any installment of Rent or other sum due from Tenant shall not be received by
Landlord or Landlord's designee within three (3) days after such amount shall be
due, Tenant 

                                       8
<PAGE>
 
shall pay to Landlord a late charge of Fifty Dollars ($50.00) plus interest at
two percent (2%) above prime of the amount due on each past due amount. The
parties hereby agree that such late charge by Landlord shall in no event
constitute a waiver of Tenant's default with respect to such overdue amount, nor
prevent Landlord from exercising any of the other rights and remedies granted at
law or equity or pursuant to this Lease.

      4.09 Acceleration of Payment. In the event a late charge becomes payable
           ------------------------                                           
pursuant to Section 4.08 of this Lease for three installments of Rent within a
twelve (12) month period, then all subsequent Rent payments shall immediately
and automatically become payable by Tenant quarterly in advance instead of
monthly.

      4.10 Definition of Rent. Any and all payments of Basic Rent and any and
           -------------------                                               
all Taxes and Cost of Operation and Maintenance, CPI Escalation Amounts, fees,
charges, costs, expenses, insurance obligations, late charges, and all other
payments, disbursements or reimbursements which are attributable to, payable by
or the responsibility of Tenant under this Lease (collectively "Rent")
constitute "Rent" within the meaning of California Civil Code Section 1951(a).
Any Rent payable to Landlord by Tenant for any fractional month shall be
prorated based on a three hundred sixty (360) day year. All Rent owed by Tenant
under this Lease shall be paid to Landlord in lawful money of the United States
of America at the location specified by Landlord pursuant to Section 26.01 of
the Lease. All payments of Rent owed by Tenant under this Lease shall be paid
without deduction, off-set abatement or counterclaim except as specifically
permitted by this Lease.

                                SECURITY DEPOSIT
                                ----------------

     5.01 Concurrently with Tenant's execution of this Lease, Tenant shall
deposit with Landlord the amount of the security deposit as set forth in the
Fundamental Lease Provisions hereof. Said sum shall be held by Landlord as a
security deposit for the faithful performance by Tenant of all of the terms,
covenants and conditions of this Lease, including but not limited to the
provisions relating to the payment of Rent and payment of any other amount which
Landlord may spend by reason of Tenant's default or to compensate Landlord for
any other loss or damage which Landlord may suffer by reason of Tenant's
default. If any portion of said deposit is so used or applied, Tenant shall,
within ten (10) days after written demand therefor, deposit the original amount
with Landlord. Tenant's failure to do so shall be a material breach of this
Lease. Landlord shall not be required to keep the security deposit separate from
its general funds, and Tenant shall not be entitled to interest on such deposit.
If Tenant shall fully and faithfully perform every provision of the Leans to be
performed by it, the security deposit or any balance thereof shall be returned
to Tenant (or, at Landlord's option, to the last assignee of Tenant's interests
hereunder) at the expiration of this Lease Term and after Tenant has vacated the
Premises. With full knowledge of the rights and privileges created therein,
Tenant hereby expressly waives all rights and privileges under Section 1950.7 of
the Civil Code of the State of California and any amendments thereto, or of any
similar law which may hereafter be passed by the Stale of California.


                                   ARTICLE VI
                             COMPLETION OF PREMISES
                             ----------------------

      6.01 Landlord's Work. The Premises shall be completed by Landlord
           ----------------                                            
substantially in accordance with the description of the "Layout Work" set forth
in Exhibit "D" (Landlords Work Letter) attached hereto and incorporated herein
by this reference. Landlord's obligation for completion of the Premises shall be
defined and limited by said Exhibit "D" and Landlord shall not be required to
furnish or install any item not indicated thereon. The Premises shall be deemed
"Ready for Occupancy" on the date on which Tenant receives Landlord's
certificate that the work described in Exhibit "D", together with the common
facilities for access and service to the Premises, has been substantially
completed except for items of work and adjustment of equipment and fixtures
which can be completed after occupancy has been taken without causing
substantial interference with Tenant's use of the Premises (i.e., so-called
"punch list" items). The tenant improvement work shall be done by Landlord's
contractor, as set forth in Exhibit "D" and any additional changes or
improvements to the Premises shall be at Tenant's sole cost and expense.

      6.02 Tenant Delays. If Tenant shall cause any delay in the construction of
           --------------                                                       
the Premises, whether by reason of any failure by Tenant to comply with the
applicable time schedule set forth in Exhibit "D" or by Tenant's requirement of
materials or installations different from Landlord's standard tenant improvement
work as set forth in Exhibit "D", or by delays in performance or completion by a
party employed by Tenant, or by reason of changes in the work ordered by Tenant,
then notwithstanding anything to the contrary contained in said Exhibit "D", the
Commencement Date shall be the date which Landlord in its judgment determines
could have been expected to be the Commencement Date but for such delay.

     6.03 Excess Costs. Tenant shall pay to Landlord at the time and in the
          -------------                                                    
manner specified in Exhibit "D" the entire balance of any and all costs of work
and improvements different from, supplemental or additional to, Landlord's
standard tenant improvement work as set forth in Exhibit "D.1". Tenant shall
also pay to Landlord the entire amount of any extra expenses incurred by
Landlord as specified in Exhibit "D" for any required alterations in the
Property, provided Landlord in its sole discretion agrees to such alterations,
as soon thereafter as Landlord determines such amount and submits a reasonably
detailed statement therefor to Tenant. Upon default by Tenant in payment of any
sum to be paid by Tenant pursuant to Exhibit "D", Landlord shall (in addition
to all other remedies) have the rights as in the case of default in Rent under
the Lease.

      6.04 Tenant Improvements - Treatment at End of Lease. All Alterations and
           ------------------------------------------------                    
any Tenant Improvements (as defined in attached Exhibit "D") made by or for
Tenant, whether temporary or permanent in character, made either by Landlord or
Tenant, shall become Landlord's property at the expiration or termination of
this Lease, and shall be surrendered to Landlord in good condition upon
expiration of the Term or termination of this Lease without compensation to
Tenant; provided however, that at the election of Landlord, exercisable by
notice to Tenant at the time Landlord consents to the plans for the Alterations
or the Tenant Improvements or at any time prior to the termination of this
Lease, Tenant shall, at Tenant's sole expense, prior to the expiration of the
Term remove from the Premises Tenant Improvements and/or Alterations (or that
portion of Tenant Improvements and/or Alterations required by Landlord, pursuant
to such notice, to be removed by Tenant) and repair all damage to the Premises
caused by such removal. All of Tenant's personal property, including moveable
furniture, trade fixtures, and equipment not attached to the Property or the
Premises, shall be completely removed by Tenant prior to the expiration of the
Term. Provided, however, that Tenant shall repair all damage caused by such
removal prior to the expiration of the Term, and provided further, that any of
Tenant's personal property not so removed shall, at the option of Landlord,
automatically become the property of Landlord. Thereafter, Landlord may retain
or dispose of in any manner the personal property not so removed, without
liability to Tenant. Once the Alterations are completed, they shall be treated
the same as Tenant Improvements.

                               USE OF THE PREMISES
                               -------------------


      7.01 Permitted Use. Tenant shall use the Premises for general office
           --------------                                                 
purposes only in keeping with the character of a first-class office building
complex and other lawful uses incidental to such office use and specifically for
the use as general office only. Tenant shall not use or permit the Premises
           --------------------                                            
to be used for any other purpose.

      7.02 Effect of Use on Insurance. Tenant shall not do or permit anything
           ---------------------------                                       
done in or about the Premises nor bring or keep anything therein which will in
any way increase the existing rate or affect any fire or other insurance upon
the Property or any of its contents, or cause a cancellation of any insurance
policy covering said Property or any part thereof or any of its contents, nor
shall Tenant sell or permit to be kept, used or sold in or about said Premises
any articles which may be prohibited by a standard form policy of insurance,
without limitation upon Landlord's remedies for Tenant's breach of this
Covenant, Tenant shall promptly upon demand reimburse Landlord for any
additional premium charged under such policy by reason of Tenant's failure to
comply with the provisions of this Article.

      7.03 Prohibited Uses. Tenant shall not do or permit anything to be done in
           ----------------                                                     
or about the Premises which will in any way obstruct or interfere with the
rights of other tenants of the Property or injure them, nor shall Tenant cause,
maintain or permit any nuisance in, on or about the Premises. Further, Tenant
shall not violate any of the Rules and Regulations set forth in Exhibit "E".

      7.04 Safety. Tenant shall keep the Premises equipped with all safety
           -------                                                         
appliances required by law or ordinance or any other regulation of any public
authority because of any use made by Tenant. Tenant shall procure all licenses
and permits so required because of such use and, if requested by Landlord, shall
do any work so required because of such use at Tenants expense, it being
understood that the foregoing provisions shall not be construed to broaden in
any way the uses on the Premises permitted under this Lease.

      7.05 No Illegal Use. Tenant shall not use the Premises in any way, or
           ---------------                                                 
permit anything to be done in or about the Premises, which will conflict with
Law, ordinance or governmental rule or regulation or requirement of duly
constituted public authorities now in force or which may hereafter be enacted or
promulgated. Tenant shall at its sole cost and expense promptly comply with all
laws, statutes, ordinances and governmental rules, regulations or requirements
now in force or which may hereafter be in force and the requirements of any
board of fire underwriters or other similar body now or hereafter constituted
relating to or affecting the condition, use or occupancy of the Premises.

      7.06 Hazardous Materials. Tenant shall not (either with or without
           --------------------                                         
negligence) cause or permit the escape, disposal or release of any biologically
or chemically active or other hazardous substances, or materials. Tenant shall
not allow the storage or use of such substances or materials in any manner not
sanctioned by law or by the highest standards prevailing in the industry for the
storage and use of such substances or materials, nor allow to be brought into
the Property any such materials or substances except to use in the ordinary
course of Tenant's business, and then only after written notice is given to
Landlord of the identity of such substances or materials. Without limitation,
hazardous substances and materials shall include those described in the
Comprehensive Environmental Response, Compensation and Liability Act of 1980, as
amended, 42 U.S.C. section 9601 et seq., the Resource Conservation and Recovery
Act, as amended, 42 U.S.C. Section 6901 et seq., any applicable state or local
laws and the regulations adopted under these acts. If any lender or governmental
agency shall ever require testing to ascertain whether or not there has been any
release of hazardous materials, then the reasonable costs thereof shall be
reimbursed by Tenant to Landlord upon demand as additional charges if such
requirement applies to the Premises. In addition, Tenant shall execute
affidavits, representations and the like from time to time at Landlord's request
concerning Tenant's best knowledge and belief regarding the presence of
hazardous substances or materials on the Premises. In all events, Tenant shall
indemnify Landlord in the manner elsewhere provided in this Lease from any
release of hazardous materials on the Premises occurring while Tenant is in
possession, or elsewhere if caused by Tenant or persons acting under Tenant. The
within covenants shall survive the expiration or earlier termination of this
Lease term.

      7.07 No Warranty. Tenant agrees that neither Landlord nor any agent of
           ------------                                                     
Landlord has made any representation or warranty as to the suitability of the
Premises for the conduct of Tenant's business, nor has Landlord agreed to
undertake any modification, alteration or improvement to the Premises except as
provided in this Lease, Tenant further agrees that neither Landlord nor any
agent of Landlord has made any representation or warranty with respect to the
physical condition of the Property, the land upon which it is erected, the
Parking Facilities, or the Premises, or the expenses of operation of the
Property, the Parking Facilities, or the Premises, or any other matter or thing
affecting or related to the Premises, except as herein expressly set forth, and
no rights, easements or licenses are acquired by Tenant by implication or
otherwise except as expressly set forth in the provisions of this Lease. Except
as set forth in this Lease, Tenant shall inspect the Parking Facilities, the
Property and the Premises prior to the delivery of possession of the Premises

Lease; and Landlord shall not be obligated to repair any damage thereto or
replace the same.

      C. Worker's Compensation. Worker's Compensation and Employer's Liability
         ----------------------                                                
insurance as required by law.

      D. Business Interruption. Loss of income and business interruption
         ----------------------                                         
insurance in such amounts as will reimburse Tenant for direct or indirect loss
of earnings attributable to all perils commonly insured against by prudent
tenants or attributable to prevention of access to the Premises or to the
Property as a result of such perils.

      E. Other Insurance. Any other forms of insurance as the Tenant, the
         ----------------                                                
Landlord, or the mortgagees may reasonably require from time to time in form,
in amounts and for insurance risks against which a prudent tenant would protect
itself.

      F. Technical Requirements. Tenant shall provide Landlord, prior to the
         -----------------------                                            
Commencement Date, and thereafter as Landlord may reasonably request,
certificates issued by the insurance companies which are providing coverage,
which insurance companies are permitted to do business in the state of
California, which must have a financial rating of at least an AXIII status as
rated in the most recent edition of Best's Insurance Reports, evidencing
compliance with the above insurance requirements and naming Landlord and
Landlord's Manager as additional insureds. All policies shall provide for notice
of renewal to Landlord not less than thirty (30) days prior to expiration, and
shall provide for notice to Landlord of cancellation prior to said cancellation.
Landlord may upon thirty (30) days' notice to Tenant, require an increase of the
above liability limits if Landlord deems it to be inadequate when compared to
the then existing comparable office lease practice in the area in which the
Property is located, or as Landlord may reasonably require. The limits of said
insurance shall not, however, limit the liability of Tenant under Section 12.01
above. Tenant shall have the right to provide such insurance coverage pursuant
to blanket policies obtained by the Tenant provided such blanket policies
expressly afford coverage to the Premises and to Tenant as required by this
Lease.

      13.02 Assumption of Risk. Tenant, as a material part of the consideration
            -------------------                                                
to Landlord, hereby assumes all risk of damage to Tenant's business and personal
property or injury to persons, in, upon or about the Premises from any cause and
Tenant hereby waives all such claims against Landlord. Landlord and Landlord's
Employees shall not be liable for any damage to any of Tenant's personal
property entrusted to Landlord or Landlord's Employees, nor for loss or damage
to any of Tenant's personal property by theft or otherwise. Tenant shall give
prompt notice to Landlord in case of fire or accidents in the Premises or in the
Property.

      13.03 Waiver of Subrogation. Any policy or policies of fire, extended
            ----------------------                                         
coverage or similar casualty insurance which Tenant obtains in connection with
the Premises shall include a clause or endorsement denying the insurer any right
of subrogation against Landlord to the extent rights have been waived by the
insured prior to the occurrence of injury or loss. Tenant hereby waives any
rights of recovery against Landlord for injury or loss due to hazards covered by
insurance to the extent of the injury or loss covered thereby.

      13.04 Tenant's Failure to Insure. In the event Tenant fails to procure and
            ---------------------------                                         
maintain insurance as required by this Article XIII, Landlord may, but shall not
be required to, procure and maintain same at the sole cost and expense of the
Tenant or deem such failure as a material breach of the Lease subject to all the
rights and remedies as provided herein and by law.


                                   ARTICLE XIV
                                MECHANICS' LIENS
                                ----------------

      14.01 Not Permitted. Tenant hereby agrees that it will pay or cause to be
            --------------                                                     
paid all costs for work done by it or caused to be done by it on the Premises.
Tenant shall not permit any mechanics', laborers', materialmen's or similar
liens on account of work done by Tenant or persons claiming under it to be filed
against the Property, nor against Tenant's leasehold interest in the Premises.
If Tenant shall desire to contest any claim of lien, it shall furnish Landlord
adequate security of the value or in the amount of the claim, plus estimated
costs and interest, or a bond of a responsible corporate surety in such amount
as is necessary to release the lien; provided, however, if a final judgment
establishing the validity or existence of a lien for any amount is entered,
Tenant shall pay and satisfy it.

      14.02 Posting. Landlord shall have the right at all reasonable times to
            --------                                                         
post and keep posted on the Premises any notices which it deems necessary for
protection from such liens.

      14.03 Landlord's Right to Cause Release. Subject to Section 14.01 above,
            ----------------------------------                                
if any such liens are filed, Landlord may, without waiving its rights and
remedies based on such breach of Tenant and without releasing Tenant from any of
its obligations, cause such liens to be released by any means it shall deem
proper, including payment and satisfaction of the claim giving rise to such
lien. Tenant shall pay Landlord at once, upon notice by Landlord, any sum paid
by Landlord to remove such liens, together with interest, and all related costs.

                             DAMAGE AND RESTORATION
                             ----------------------

      15.01 Loss Covered By Insurance. If at any time prior to the expiration or
            --------------------------                                          
termination of this Lease, the Premises or the Property are wholly or partially
damaged or destroyed by a risk, the loss to Landlord from which is fully covered
by insurance maintained by Landlord or for Landlord's benefit, which risk
renders the Premises totally or partially inaccessible or unusable by Tenant in
the ordinary conduct of Tenant's business, then:

      A. Repairs Which Can Be Completed Within One Year. If all repairs to such
         -----------------------------------------------                       
Premises or Property can, in Landlord's judgment, be completed within one (1)
year following the date of notice to Landlord of such damage or destruction
without the payment of overtime or other premiums, and if such damage or
destruction is not the result of the intentional willful misconduct of Tenant or
Tenant's employees, guests or invitees, Landlord shall, at Landlord's expense,
repair the same and this Lease shall remain in full force and effect and a
proportionate reduction of Rental shall be allowed Tenant for such portion of
the Premises as shall be rendered inaccessible or unusable to Tenant, and which
is not used by Tenant, during the period of time that such portion is unusable
or inaccessible. There shall be no proportionate reduction of Rental by reason
of any portion of the Premises being unusable or inaccessible due to the
intentional willful misconduct of Tenant or Tenant's employees for a period
equal to five (5) business days or less.

      B. Repairs Which Cannot Be Completed Within One Year. If such damage or
         --------------------------------------------------                  
destruction is not the result of the willful misconduct of Tenant or Tenant's
employees, and if all such repairs cannot, in Landlord's judgment, be completed
within one (1) year following the date of notice to Landlord of such damage or
destruction without the payment of overtime or other premiums, Landlord may, at
Landlord's sole and absolute option, upon written notice to Tenant no later than
sixty (60) days after notice to Landlord of the occurrence of such damage or
destruction, elect to repair such damage or destruction at Landlord's expense,
and in such event, this Lease shall continue in full force and effect but the
Rent shall be proportionately reduced as provided in, and to the extent provided
in, section 15.01(A). If Landlord does not elect to make such repairs and
notifies Tenant of such election within the prescribed time period, then either
party may, by written notice to the other, terminate this Lease as of the date
of the occurrence of such damage or destruction, by notice given to the other.

     15.02 Loss Not Covered By Insurance. If, at any time prior to the
           ------------------------------                             
expiration of this Lease, the Premises or the Property are totally or partially
damaged or destroyed from a risk, the loss to Landlord from which is not fully
covered by insurance maintained by Landlord or for Landlord's benefit, which
damage renders the Premises inaccessible or unusable to Tenant in the ordinary
course of its business, Landlord may, at its option, upon written notice to
Tenant no later than sixty (60) days after notice to Landlord of the occurrence
of such damage or destruction, elect to repair or restore such damage or
destruction, or Landlord may elect to terminate this Lease. If Landlord elects
to repair or restore such damage or destruction, this Lease shall continue in
full force and effect but the Rental shall be proportionately reduced as
provided in, and to the extent provided in, section 15.01(A). If Landlord does
not elect by notice to Tenant to repair such damage, or if the damage cannot, in
Landlord's judgment, be completed within one (1) year following the date of
notice to Landlord of such damage or destruction, this Lease shall terminate.

     15.03 Loss Caused by Tenant or Tenant's Employees. If the Premises or the
           --------------------------------------------                       
Property are wholly or partially damaged or destroyed as a result of the
negligence or willful misconduct or omission of Tenant or Tenant's Employees and
Landlord elects to undertake to repair or restore all such damage or
destruction, such repair and restoration shall be at Tenant's sole cost and
expense, and this Lease shall continue in full force and effect without any
abatement or reduction in Rental or other payments owed by Tenant; provided
however, that Tenant shall be relieved of its obligation pursuant to this
Section 15.01(A) to the extent that insurance proceeds are collected by Landlord
with respect to insurance obtained by Landlord as part of Cost of Operation and
Maintenance, in which case Tenant shall be responsible for the payment of the
deductible and that portion not covered by the insurance.

      15.04 Destruction During Final Year. Notwithstanding anything to the
            ------------------------------                                
contrary contained in Sections 15.01, 15.02 or 15.03, if the Premises or the
Property are wholly or partially damaged or destroyed within the final twelve
(12) months of the Term or this Lease, Landlord may, at its option, by giving
Tenant notice no later than sixty (60) days after notice to Landlord of the
occurrence of such damage or destruction, elect to terminate this Lease.

      15.05 Destruction of Tenant's Personal Property, Tenant Improvements or
            ----------------------------------------------------------------
Property of Tenant's Employees. In the event of any damage to or destruction of
------------------------------
the Premises or the Property, 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 or the Alterations or Tenant Improvements or any
other improvements installed in the Premises by Tenant or Landlord, and Tenant
shall repair and restore all such personal property and Tenant Improvements at
Tenant's sole cost and expense. Landlord shall have no responsibility for any
contents placed or kept in or on the Premises or the Property by Tenant or
Tenant's Employees.

      15.06 Mutual Release. Upon any termination of this Lease under any of
            ---------------                                                  
the provisions of this Article, the parties shall be released thereby without
further obligation to the other from the date possession of the Premises is
surrendered to Landlord, except for items which have theretofore accrued and are
then unpaid.

     15.07 Delay in Restoration. Tenant shall not be released from any of its
           ---------------------                                             
obligations under this Lease by reason of fire or other casualty, except to the
extent and upon the conditions expressly stated in this Article. Notwithstanding
anything to the contrary contained in this Article, should Landlord be delayed
or prevented from repairing or restoring the damaged Premises by reason of acts
of God, war, governmental restrictions, inability to procure the necessary labor
or materials, or any other cause beyond the reasonable control of Landlord,
Landlord shall be relieved of its obligation to make such repairs or restoration
for a period equal to such delay or prevention.

     15.08 Exclusive Remedy. This Section 15.08 shall be Tenant's sole and
           -----------------                                              
exclusive remedy in the event of damage or destruction to the Premises or the
Property, and Tenant, as a material inducement to Landlord entering into this
Lease, irrevocably waives and releases Tenant's rights under California Civil
Code Sections 1932 and 1933(4). No damages, compensation or claim shall be
payable by Landlord for any inconvenience, any interruption or cessation of
Tenant's business, or any annoyance, arising from any damage to or destruction
of all or any portion of the Premises or the Property.


                                   ARTICLE XVI
                                  CONDEMNATION
                                  ------------

     16.01 Condemnation. If all or any part of the Premises shall be taken or
           -------------                                                     
appropriated for public or quasi-public use by the right of eminent domain, with
or without litigation or transferred by agreement in connection with such public
or quasi-public use, either party hereto shall have the right at its option
exercisable within thirty (30) days of receipt of notice of such taking to
terminate this Lease as of the date possession is taken by the condemning
authority, provided, however, that before Tenant may terminate this Lease by
reason of taking or appropriation as provided hereinabove, such taking or
appropriation shall be of such an extent and nature as to substantially
handicap, impede or impair Tenant's use of the Premises. If any part of the
Property other than the Premises shall be so taken or appropriated, Landlord
shall have the right at its option to terminate this Lease. In the event of a
partial taking which does not result in a termination of this Lease, Basic Rent
shall be equitably abated to the extent Tenant's square footage has been taken.
A sale by Landlord under threat of condemnation shall constitute a "taking" for
the purpose of this Article.

     16.02 Restoration. In the event of a partial taking which does not result
           ------------                                                       
in a termination of this Lease, Landlord shall proceed with reasonable diligence
to restore the remaining portion of the Premises (other than Tenant's property
or any of Tenant's goods, furniture or furnishings) as nearly as practicable to
its condition prior to such condemnation or taking. Tenant agrees that
Landlord's obligation to restore is limited by the provisions of Section 16.01
above.

     16.03 Award. In the event of any condemnation or taking of all or a part of
           ------                                                               
the Property, Landlord shall be entitled to receive the entire award in the
condemnation proceeding, including any award made for the value of the estate
vested by this Lease in Tenant, and Tenant hereby assigns to Landlord any and
all right, title and interest of Tenant now or hereafter arising in or to any
such award or any part thereof, and Tenant shall be entitled to receive no part
of such award; provided, however, that nothing shall preclude Tenant from
intervening in any such condemnation proceeding to claim or receive from the
condemning authority any compensation to which Tenant may otherwise lawfully be
entitled in such case with respect only to Tenant's personal property or for
relocation costs.

      16.04 Condemnation for a Limited Period. Notwithstanding the provisions of
            ----------------------------------                                  
Sections 16.01, 16.02 and 16.03 above, if all or any portion of the Premises
shall be condemned or taken for governmental occupancy for a limited period,
this Lease shall not terminate, there shall be no abatement of Basic Rent or
additional rent payable hereunder, and Tenant shall be entitled to receive the
entire award therefor (whether paid as damages, rent or otherwise) unless the
period of governmental occupancy extends beyond the expiration of this Lease, in
which case Landlord shall be entitled to such part of such award as shall be
properly allocable to the cost of restoration of the Premises, and the balance
of such award shall be apportioned between Landlord and Tenant as of the date of
such expiration. If the termination of such governmental occupancy is prior to
expiration of this Lease, Tenant shall, to the extent an award has been made for
the purpose of restoring the Premises, after application for the diligent
pursuit of such award by Tenant, restore the Premises as nearly as possible to
the condition of the Premises prior to the condemnation or taking.

                                QUIET POSSESSION
                                ----------------

      17.01 Landlord covenants and agrees with Tenant that upon paying the Rent
and other monetary sums due under this Lease, and performing the covenants and
conditions on the part of Tenant to be performed hereunder, Tenant shall quietly
have, hold and enjoy the Premises during the term of this Lease.

      18.01 Tenant's Statement. Within ten (10) days after written request
            -------------------                                           
therefor from Landlord, Tenant shall execute and deliver to Landlord a statement
as Landlord may reasonably request, or as a prospective purchaser or
encumbrancer of the Property may request (i) certifying that this Lease is in
full force and effect, without modification (or if modified, stating the nature
of such modification and certifying that this Lease, as modified is in full
force and effect) and the date to which the rent and other charges are paid in
advance, if any, (ii) acknowledging that there are not any uncured defaults on
the part of Landlord hereunder, or specifying such defaults if they are claimed,
and (iii} any other requirements of a prospective purchaser or encumbrancer of
the Premises. Any such statements may be conclusively relied upon by any
prospective purchaser or encumbrancer of the Property. Failure by Tenant to
deliver the Estoppel Certificate within the ten (10) day period shall be deemed
to conclusively establish that this Lease is in full force and effect and has
not been modified except as may be represented by Landlord.

                                    DEFAULTS
                                    --------

      19.01 The occurrence of any of the following shall constitute a material
default and breach of this Lease by Tenant:

      A. Failure to Pay Rent. If Tenant shall fail to make any payment of Rent
         --------------------                                                  
owed by Tenant under this Lease, as and when due, and where such failure is not
cured within three (3) days following receipt of notice by Tenant from Landlord.
Such three (3) day notice is in lieu of, and not in addition to, any notice
required under Section 1161 of the California Code of Civil Procedure.

      B. Abandonment. The abandonment or vacation of the Premises by Tenant for
         ------------                                                          
ten (10) consecutive days.

      C. Non-Performance of Other Covenants. A failure by Tenant to observe and
         -----------------------------------                                   
perform any other provision of this Lease to be observed or performed by Tenant,
where such failure continues for ten (10) days after written notice thereof by
Landlord to Tenant; provided, however, that if the nature of such default is
such that the same cannot reasonably be cured within such ten (10) day period
Tenant shall not be deemed to be in default if Tenant shall within such period
commence such cure and thereafter diligently prosecute the same to completion.

      D. Bankruptcy; Assignment. The making by Tenant or by any guarantor of
         -----------------------                                            
this Lease of any general assignment for the benefit of creditors; the filing by
or against Tenant or by or against any guarantor of this Lease of a petition to
have Tenant or any guarantor of this Lease adjudged a bankrupt or of a petition
for reorganization or arrangement under any law relating to bankruptcy (unless
in the case of a petition filed against Tenant or any guarantor of this Lease,
the same is dismissed within sixty (60) days); the appointment of a trustee or
receiver to take possession of substantially all of Tenant's assets or all of
the assets of such guarantor of this Lease located at the Premises or of
Tenant's interest or of such guarantor's interest in this Lease where possession
is not restored to Tenant or to such guarantor within thirty (30) days; or the
attachment, execution or other judicial seizure of substantially all of Tenant's
or such guarantor's assets located at the Premises or of Tenant's or such
guarantor's interest in this Lease, where such seizure is not discharged within
thirty (30) days. In the event Tenant files a petition for reorganization,
arrangement or liquidation under any law relating to bankruptcy, or such a
petition is involuntarily filed against Tenant, Landlord shall be entitled to
recover from 

                                       19
<PAGE>
 
Tenant, or any assignee or sublessee of Tenant's rights and obligations
hereunder, all reasonable attorney's fees and costs related to Landlord's
attempts to regain possession of the Premises or to cause an assumption (and
assignment) of this Lease by Tenant through the bankruptcy court. Any assignee
or sublessee of Tenant's interest in this Lease as a result of a bankruptcy
proceeding shall be jointly and severally liable with Tenant for payment of said
reasonable attorney's fees within ten (10) days of proper billing.

      19.02 Recovery from Tenant on Termination. In the event of any such
            ------------------------------------                          
default by Tenant, then in addition to any other remedies available to Landlord
now or later permitted by law or in equity, Landlord shall have the immediate
option to terminate this Lease and all rights of Tenant hereunder by giving
written notice of such intention to terminate. In the event that Landlord shall
elect to so terminate this Lease then Landlord may recover from Tenant;

      A. Past Rent. The worth at the time of award of any unpaid Rent or other
         ----------                                                           
charges which had been earned at the time of such termination; plus

      B. Rent Prior to Award. The worth at the time of award of the amount by
         --------------------                                                
which the unpaid rent would have been earned after termination until the time of
award exceeds the amount of such rental loss Tenant proves could have been
reasonably avoided; plus

      C. Rent After Award. The worth at the time of award of the amount by which
         -----------------                                                      
the unpaid rent for the balance of the term of this Lease after the time of
award exceeds the amount of such rental loss that Tenant proves could be
reasonably avoided; plus

      D. Proximately Caused Damages. Any other amount necessary to compensate
         ---------------------------                                         
Landlord for all the detriment proximately caused by Tenant's failure to perform
its obligations under this Lease or which in the ordinary course of things would
be likely to result therefrom; and


      E. Additional Damages. At Landlord's election, such other amounts in
         -------------------                                              
addition to or in lieu of the foregoing as may be permitted from time to time by
applicable California law.

      19.03 Worth at Time of Award. As used in Section 19.02(A) and 19.02(B)
            -----------------------                                         
above, the "worth at the time of award" is computed by allowing interest at the
Bank of America prime commercial rate plus two percent (2%), but not to exceed
the maximum rate of interest allowed by law. As used in Section 19.02(C) above,
the "worth at the time of award" is computed by discounting such amount at the
discount rate of the Federal Reserve Bank of San Francisco at the time of award
plus one percent (1%).

      19.04 Vacation or Abandonment. In the event of the vacation or abandonment
            ------------------------                                            
of the Premises by Tenant or in the event that Landlord shall elect to re-enter
as provided above or shall take possession of the Premises pursuant to legal
proceeding or pursuant to any notice provided by law, then if Landlord does not
elect to terminate this Lease as provided above, Landlord may from time to time,
without terminating this Lease, either recover all rent as it becomes due or
relet the Premises or any part thereof for such term and upon such terms and
conditions as Landlord in its sole discretion may deem advisable, Landlord
hereby reserving the right in such instances to make alterations and repairs to
the Premises.

      19.05 Election to Terminate Lease. No re-entry into or taking of
            ----------------------------                              
possession of the Premises by Landlord pursuant to this Article shall be
construed as an election to terminate this Lease unless a written notice of such
intention be given to Tenant or unless the termination thereof be decreed by a
court of competent jurisdiction. Notwithstanding any reletting without
termination by Landlord because of any default by Tenant, Landlord may at any
time after such reletting elect to terminate this Lease for any such default.

      19.06 Default by Landlord. Landlord shall not be deemed to be in default
            --------------------                                              
in the performance of any obligation required by it under this Lease, or under
any agreement executed in connection herewith, unless and until it has failed to
perform such obligation within twenty (20) days after receipt of written notice
by Tenant to Landlord, specifying wherein Landlord has failed to perform such
obligation provided, however, if the nature of Landlord's obligation is such
that thirty (30) days are required for its performance, then Landlord shall not
be deemed to be in default if it shall commence such performance within such
thirty (30) day period and thereafter diligently prosecute the same to
completion.

      19.07 Right of Entry and Re-Let. In the event of any default by Tenant,
            --------------------------                                       
Landlord shall also have the right, with or without terminating this Lease, to
enter the Premises and remove all persons and personal property from the
Premises, such property being removed and stored in a public warehouse or
elsewhere at Tenant's sole cost and expense. No removal by Landlord of any
persons or property in the Premises shall constitute an election to terminate
this Lease. Such an election to terminate may only be made by Landlord in
writing, or decreed by a court of competent jurisdiction. Landlord's right of
entry shall include the right to remodel the Premises and re-let the Premises.
All costs incurred in such entry and re-letting shall be paid by Tenant. In the
event that Landlord shall elect to so relet, then rent received by Landlord from
such reletting shall be applied; first, to the payment of any indebtedness other

                                       20
<PAGE>
 
than rent due hereunder from Tenant to Landlord; second, to the payment of any
cost of such reletting; third, to the payment of the cost of any alterations and
repairs to the Premises; fourth, to the payment of rent due and unpaid
hereunder; and the residue, if any, shall be held by Landlord and applied in
payment of future rent as the same may become due and payable hereunder. Rents
collected by Landlord from any other tenant which occupies the Premises shall be
offset against the amounts owed to Landlord by Tenant. Tenant shall be
responsible for any amounts not recovered by Landlord from any other tenant. Any
payments made by Tenant shall be credited to the amounts owed by Tenant in the
sole order and discretion of Landlord. No entry by Landlord shall prevent
Landlord from later terminating this Lease by written notice.

      19.08 Waiver of Redemption. Tenant hereby waives, for itself and all
            ---------------------                                         
persons claiming by and under Tenant, all rights and privileges which it might
have under California Code of Civil Procedure 1174 and any present or future law
to redeem the Premises or to continue the Lease after being dispossessed or
ejected from the Premises.

      19.09 Right to Perform. If Tenant fails to perform any covenant or
            -----------------                                           
condition to be performed by Tenant, Landlord may perform such covenant or
condition at its option, after notice to Tenant. All costs incurred by Landlord
in so performing shall immediately be reimbursed to Landlord by Tenant, together
with interest at the legal rate allowed by law, computed from the due date. Any
performance by Landlord of Tenant's obligations shall not waive or cure such
default. Landlord may perform Tenant's defaulted obligations at Tenant's sole
cost and expense without notice in the case of any emergency. All costs and
expenses incurred by Landlord, including reasonable attorney's fees (whether or
not legal proceedings are instituted) in collecting rent or enforcing the
obligations of Tenant under the Lease shall be paid by Tenant to Landlord upon
demand.

      19.10 Remedies Not Exclusive. The rights and remedies of Landlord set
            -----------------------                                        
forth herein are not exclusive, and Landlord may exercise any other right or
remedy available to it under this Lease, at law or in equity.

      19.11 Credit Reporting. Notwithstanding those terms and conditions
            -----------------                                           
contained herein, it is hereby agreed and understood by Tenant that in the
event Tenant fails to pay any sums due and owing under this Lease, when due
Landlord, Landlord may, at Landlord's sole and absolute discretion, take any and
all remedial measures necessary to effectuate payment of arrearages, including
but not limited to noticing any or all credit reporting agencies including TRW.

      19.12 N.S.F. Checks. It is hereby agreed by and between the parties herein
            --------------                                                      
that in the event Tenant's payment of Basic Rent and/or additional rent or any
such other costs or expenses required to be paid by Tenant under this Lease
shall be returned to Landlord for insufficient funds, Tenant shall pay forthwith
upon demand, the sum of Fifty Dollars ($50.00) as Landlord's administrative fee
per check. Further, it is agreed and understood that in the event Tenant tenders
a bad check to Landlord, Landlord may, in its sole discretion, require Tenant to
pay any future sum or sums required in this Lease by Cashier's Check for the
remainder of the lease term.

                              SURRENDER OF PREMISES
                              ---------------------

      20.01 At the expiration or termination of this Lease, Tenant shall
surrender to Landlord the Premises and all alterations and additions thereto in
good order, repair and condition (except for ordinary wear and tear). Tenant
shall remove all personal property and trade fixtures prior to the expiration of
the term, including any signs, notices and displays placed by Tenant. Tenant
shall perform all necessary restoration, including, without limitation,
restoration made necessary by the removal of Tenant's personal property and
trade fixtures (or of any alterations required to be removed by Tenant pursuant
to the provisions of Section 6.04 hereof) prior to the expiration or termination
of this Lease.

      Landlord can elect to retain or dispose of, in any manner, any
alterations, Tenant's personal property or trade fixtures that Tenant does not
remove from the Premises on expiration or termination of the term as allowed or
required by this Lease. Title to any such alterations, Tenant's personal
property or trade fixtures that Landlord elects to retain or dispose of on
expiration of the term shall vest in Landlord. Tenant waives all claims against
Landlord for any damage to Tenant resulting from Landlord's retention or
disposition of any such alterations, Tenant's personal property or trade
fixtures. Tenant shall be liable to Landlord for Landlord's costs for storing,
removing and disposing of any alterations, Tenant's personal property or trade
fixtures and shall indemnify and hold Landlord harmless from the claim of any
third party to an interest in said personal property.

                                   ARTICLE XXI
                      ASSIGNMENT, SUBLEASE AND ENCUMBRANCE
                      ------------------------------------

      21.01 Right to Assign, Sublease and Encumber. Landlord and Tenant
            ---------------------------------------                     
recognize and specifically agree that this Section 21.01 is, in part, an
economic provision, like Rent, and that the Landlord's right to recapture, and
to share in excess Base Rent, was granted by Tenant to Landlord in consideration
of certain other economic concessions granted by Landlord to Tenant.

                                       21
<PAGE>
 
      Tenant may voluntarily assign or encumber its interest in this Lease or in
the Premises, or sublease all or any part of the premises, or allow any other
person or entity to occupy or use all or any part of the Premises, upon
complying with Section 21.02 and first obtaining Landlord's prior written
consent. Any assignment, encumbrance or sublease without Landlord's prior
written consent shall be voidable, at Landlord's election, and shall constitute
a default. No consent to an assignment, encumbrance, or sublease shall
constitute a further waiver of the provisions of this Section. Tenant hereby
agrees to use Landlord's sublease and/or Assignment form.

      21.02 Procedure For Assignment and Sublease. Tenant shall advise Landlord
            --------------------------------------                             
by notice of (1) Tenant's intent to assign or encumber this Lease, or sublease
all or part of the Premises, (2) the name of the proposed assignee or sublessee,
and evidence reasonably satisfactory to Landlord that such proposed assignee or
sublessee is comparable in reputation, stature and financial condition to the
other tenants then leasing comparable space in the Property) and (3) the terms
of the proposed assignment or subletting, and Landlord shall, within thirty (30)
days of receipt of such notice, and any additional information reasonably
requested by Landlord concerning the proposed assignee's or sublessee's
financial responsibility, elect one of the following:

      A. Consent to such proposed assignment, encumbrance or sublease;

      B. Refuse such consent, which refusal shall be on reasonable grounds; or

      C. Elect to terminate the Lease in the event of an assignment, or in the
case of a sublease, terminate this Lease as to the portion of the Premises
proposed to be sublet for the remaining Term of the Lease, which termination
will be effective forty-five (45) days after Landlord sends Tenant a timely
notice electing to exercise such termination right.

      21.03 Affiliated Companies/Restructuring of Business Organization.
            ------------------------------------------------------------
Occupancy of all or part of the Premises by parent, subsidiary, or affiliated
companies of Tenant shall not be deemed an assignment or subletting provided
that such parent, subsidiary or affiliated companies were not formed as a
subterfuge to avoid the obligation of this Section 21.01. If Tenant is a
corporation, unincorporated association, trust or general or limited
partnership, then the sale, assignment, transfer or hypothecation of any shares,
partnership interest, or other ownership interest of such entity which from time
to time in the aggregate exceeds twenty-five percent (25%) of the total
outstanding shares shall be deemed an assignment subject to the provisions of
this Section 21.01.

      21.04 Reasonable Grounds for Withholding Landlord's Consent to a
            ----------------------------------------------------------
Proposed Assignment or Sublease. Without limiting Landlord's right to refuse to
--------------------------------                                               
consent to an assignment or sublease for good, sufficient and reasonable cause,
it shall not be unreasonable for Landlord to withhold its consent to an
assignment or a sublease because the proposed assignee or sublessee:

      A. Is a government entity;

      B. Is an occupant of the Property, and the Property is not ninety-five
percent (95%) leased;

      C. Does not have a financial condition sufficient to perform the
obligations under the proposed sublease or assignment;

      D. Intends to use the Premises for a use not permitted under Article VII
and/or Exhibit "E".

      E. Would violate exclusives granted by Landlord to other tenants of the
Property by use of the Premises; and

      F. would result in more people working at, or visiting, the Premises than
the number of people who worked at, or visited, the Premises, at the time when
Tenant was the sole occupant of the Premises.

      21.05 Tenant Not Released. Unless Landlord elects to terminate the entire
            --------------------                                               
Lease pursuant to Section 21.07, in the event of Landlord's consent to an
assignment or sublease, Tenant shall not be released from any of its obligations
pursuant to this Lease.

      21.06 Landlord's Right to Assign. Landlord shall have the right to sell,
            ---------------------------                                       
convey, transfer, and/or assign (collectively "Transfer") any of its rights and
obligations under the Lease. After such Transfer, Landlord shall be relieved of
any and all obligations under this Lease.

      21.07 Recapture. If Tenant proposes to assign this Lease, Landlord may, at
            ----------                                                          
its option, exercisable upon written notice to Tenant within thirty (30) days
after Landlord's receipt of the notice from Tenant set forth in Section 21.01
above, elect to recapture the Premises and terminate this Lease. If Tenant
proposes to sublease all or part of the Premises, Landlord may, at its option
exercisable upon written notice to Tenant, within thirty (30) days after
Landlord's receipt of the notice from Tenant set forth in Section 21.01 above,
elect to recapture such portion of the Premises as Tenant proposes to sublease
and, upon such election by Landlord, this Lease shall terminate as to the
portion of the Premises recaptured. In the event a portion only of the Premises 
is

                                       22
<PAGE>
 
recaptured the rental payable under this Lease shall be proportionately
adjusted. If Landlord does not elect to recapture pursuant to this Section
21.01, Tenant may thereafter enter into a valid assignment or sublease with
respect to the Premises, provided Landlord, pursuant to this Article, consents
thereto, and provided further that (a) such assignment or sublease is executed
within ninety (90) days after notification to Landlord of such proposal, and (b)
the rental therefor is not less than that stated in such notification. Tenant
acknowledges Landlord's right to recapture is a material term bargained for by
Landlord.

      21.08 Fees for Review. In the event that Tenant shall request to assign,
            ----------------                                                  
transfer, mortgage, pledge, hypothecate or encumber this Lease or any interest
therein, or sublet the Premises or any part thereof, Tenant shall pay to
Landlord a non-refundable Five Hundred Dollars ($500.00) fee for Landlord's time
and processing efforts, and for expenses incurred by Landlord in connection with
reviewing such transaction. In addition to such fee, Tenant shall pay to
Landlord in the event Landlord retains the services of an attorney to review the
transaction, all reasonable attorneys' fees incurred by Landlord in connection
therewith but not more than Five Hundred Dollars ($500.00). Tenant shall pay
such nonreimbursable fee and such attorneys' fees to Landlord concurrently with
Tenant's execution of Landlord's form document. Payment should be in the form of
a cashiers check, after written request therefor, and such payment shall be a
condition to any approval by Landlord.

      21.09 Collection. If this Lease is assigned, or if the Premises or any
            -----------                                                     
part thereof is sublet or occupied by anybody other than Tenant, Landlord may
collect rent from the assignee, subtenant or occupant and apply the net amount
collected to the rent herein reserved and retain any excess rent so collected,
but no such assignment, subletting, occupancy or collection shall be deemed a
waiver of Tenant's covenant set forth in the first sentence of Section 4.01
above, nor shall such assignment, subletting, occupancy or collection be deemed
an acceptance by Landlord of the assignee, subtenant or occupant as tenant, or a
release of Tenant from the further performance by Tenant of covenants on the
part of Tenant herein contained.

                                  SUBORDINATION
                                  -------------

      22.01 Subordination and Attornment. Tenant covenants and agrees that it
            -----------------------------                                      
will execute without further consideration any and all instruments desired by
Landlord or Landlord's First Mortgagee subordinating this Lease in the manner
requested by landlord to all ground or underlying leases and to the lien of any
mortgagee and/or First Deed of Trust or other encumbrance which may now or
hereafter affect the Premises, together with all renewals, modifications,
consolidations, replacements or extensions thereof; provided that any or lien or
encumbrancer relying on such subordination or such additional agreements will
covenant with Tenant that this Lease shall remain in full force and effect, and
Tenant shall not be disturbed in the event of sale, foreclosure or other actions
so long as Tenant is not in default hereunder. Tenant agrees to attorn to the
successor in interest of Landlord following any transfer of such interest either
voluntarily or by operation of law and it recognizes such successor as Landlord
under this Lease. However, if Landlord or any such ground lessor or First
Mortgagee so elects, this Lease shall be deemed prior in lien to any ground
lease, mortgage, First Deed of Trust or other encumbrance upon or including the
Premises regardless of date of recording and Tenant will execute a statement in
writing to such effect at Landlord's request.

      22.02 Non-Disturbance. As long as a default by Tenant does not occur,
            ----------------                                               
regardless of any Subordination pursuant to Section 22.01 or attornment pursuant
to section 22.01, Tenant's right to occupy under this Lease shall not be
disturbed except as specifically permitted by Sections of this Lease other than
this Section 22.02. However, the person who replaces the Landlord shall not be
liable for modification to this Lease not consented to by such person, or any
offsets or defenses which Tenant had against the previous Landlord or for any
prepaid Rent or Security Deposit not received by the new Landlord.

                          SALE OF BUILDING BY LANDLORD
                          ----------------------------

     23.01 In the event of any sale or exchange of the Property, other than a
transfer for security purposes only, Landlord shall be entirely freed and
relieved of all liability under this Lease, including any obligations arising
out of any act, occurrence or omission relating to the Premises or this Lease
which occur after the consummation of such sale or exchange and/or assignment.
This Lease shall not be affected by any such sale and Tenant agrees to attorn to
the purchaser or assignee provided all Landlord's obligations hereunder are
assumed in writing by the transferee.

      24.01 Surrender of Possession. Tenant shall surrender possession of the
            ------------------------                                         
Premises immediately upon the expiration of the Term or termination of the
Lease. If the Tenant shall continue to occupy the Premises after such expiration
or termination with the consent of the Landlord, then unless Landlord and Tenant
have otherwise agreed in writing, the Tenant shall be a tenant from
month-to-month. All the terms, provisions and conditions of the Lease shall
apply to this month-to-month tenancy except those terms, provisions and
conditions pertaining to the Term, and except that the Base Rent shall be
immediately adjusted upward upon the expiration or termination of the Lease to
two hundred percent (200%) of the then prevailing Basic Rent plus Tenant's Pro
Rata Share of Taxes and Cost of Operation and Maintenance on the date of the
expiration or termination of the Lease ("Holdover Rent"). This month-to-month
tenancy may be terminated by Landlord or Tenant upon fifteen (15) days' prior
notice to the nonterminating party. In the event that Tenant fails to surrender
the Premises upon such termination or expiration or if Tenant occupies the
Premises without Landlord's written consent, then Tenant shall pay Landlord
Basic Rent equal to the Holdover Rent and shall indemnify and hold Landlord
harmless against all loss or liability resulting from or arising out of Tenant's
failure to surrender the Premises, including, but not limited to, any amounts
required to be paid to any tenant or prospective tenant who was to have occupied
the Premises after said termination or expiration and any related attorneys'
fees and brokerage commissions, and any amounts permitted to be recovered
pursuant to the California Civil Code and the California Code of Civil
Procedure.

      24.02 Payment of Money After Termination. No payment of money by Tenant to
            -----------------------------------                                 
Landlord after the termination of this Lease by Landlord, or after the giving of
any notice of termination to Tenant by Landlord which Landlord is entitled to
give Tenant under the Lease, shall reinstate, continue or extend the Term of
the Lease or shall affect any such notice given to Tenant prior to the payment
of such money, it being agreed that after the service of such notice of the
commencement of any suit by Landlord to obtain possession of the Premises,
Landlord may receive and collect when due any and all payments owed by Tenant
under the Lease, and otherwise exercise its rights and remedies. The making of
any such payments by Tenant shall not waive such notice, or in any manner affect
any pending suit or judgment obtained.

      24.03 Indemnification. If Tenant fails to surrender the Premises upon the
            ----------------                                                   
expiration of this Lease despite demand to do so by Landlord, Tenant shall
indemnify and hold Landlord harmless from all loss or liability, including
without limitation, any claim made by any succeeding tenant founded on or
resulting from such failure to surrender. The provisions of this Section 24.03
are in addition to and do not affect Landlord's right of re-entry or any rights
of Landlord hereunder or as otherwise provided by Law.

      25.01 The Rules and Regulations attached to this Lease as Exhibit "E", as
well as such reasonable rules and regulations as may be hereafter adopted by
Landlord for the safety, care, utilization and cleanliness of the Premises and
the Property, and the preservation of good order thereon, are hereby expressly
made a part hereof, and Tenant agrees to comply with such rules and regulations
and the violation of any of them shall constitute a default by Tenant under this
Lease. If there is a conflict between the rules and regulations and any of the
provisions of this Lease, the provisions of this Lease shall prevail. Landlord
shall not be responsible to Tenant for the non-performance by any other tenant
or occupant of the Property of any of said rules and regulations.

      26.01 Whenever any notice, approval, consent, request or election is given
or made pursuant to this Lease it shall be in writing. Communications and
payment shall be addressed if to Landlord at Landlord's Notice Address as set
forth below, or at such other address as may have been specified by prior
notice to Tenant, and if to Tenant, at Tenant's Notice Address as set forth
below, or at such other place as may have been specified by prior notice to

designates some other person to receive payments or notices, all payments or
notice thereafter by Tenant shall be paid or given to the agent designated until
notice to the contrary is received by Tenant from Landlord.

                                     ------

      27.01 No delay or omission in the exercise of any right or remedy of
Landlord on any default by Tenant shall impair such right or remedy or be
construed as a waiver.

      27.02 The receipt and acceptance by Landlord of delinquent rent shall not
constitute a waiver of any other default, it shall constitute only waiver of
timely payment for the particular rent payment involved.

      27.03 No act or conduct of Landlord, including, without limitation, the
acceptance of keys to the Premises, shall constitute an acceptance or the
surrender of the Premises by Tenant before the expiration of the term. Only a
notice from Landlord to Tenant shall constitute acceptance of the surrender of
the Premises and accomplish a termination of the Lease.

      27.04 Any waiver by Landlord of any default must be in writing. One or
more waivers by Landlord of a breach by Tenant of any covenant, term or
condition of this Lease shall not be construed as a waiver by Landlord of a
subsequent breach by Tenant of the same covenant, term or condition. The consent
or approval of Landlord to or of any act by Tenant of a nature requiring consent
or approval shall not be deemed to waive or render unnecessary consent to or
approval of any subsequent similar act.

of this Lease, Landlord shall maintain and operate, or cause to be maintained
and operated, automobile parking facilities ("Parking Facilities") in, adjacent
to or within a reasonable distance from the Property. Tenant's privileges during
such time with respect to the Parking Facilities shall be in accordance with the
provisions of the attached Parking Agreement (Exhibit "F"). Such parking charges
may be increased by Landlord from time-to-time upon thirty (30) days' notice to
Tenant.

      28.02 Tenant acknowledges that neither Landlord nor any agent of Landlord
has made any representation or warranty as to the suitability of the parking
areas, or as to the availability of parking space, for the conduct of Tenant's
business.

      28.03 Landlord shall have certain rights and authority relative to the use
and control of the parking areas, including, without limitation, the right to
rearrange the parking spaces and improvements of the parking areas; to take all
or any portion of the parking areas for the purpose of maintaining, repairing or
restoring same, and to do and perform such other acts in, to and with respect to
the parking areas at the sole discretion of Landlord.

      28.04 Tenant acknowledges that such parking rights are non-assignable and
any parking spaces designated for Tenant's use shall not be sublet but may be
used exclusively for Tenant's partners, associate members and employees (or
officers).

           -----                                                               
performance and enforcement of this Lease.

     29.05 Reimbursement. Except as provided for herein, in the event that at

service of process fees, filing fees (for any civil action) and reasonable
attorney fees.

one or more; and if there shall be more than one tenant, any notice required or
permitted by the terms of this Lease may be given by or to any one thereof, and
shall have the same force and effect by or to all thereof. The use of the neuter
singular pronoun to refer to Tenant shall be deemed a proper reference even
though Tenant may be an individual, a partnership, a corporation or a group of
two or more individuals or corporations. The necessary grammatical changes
required to make the provisions of this Lease apply in the plural sense where

Lease, and this Lease supersedes and cancels any and all previous negotiations,
arrangements, brochures, agreements, or representations and understandings, if
any, between the parties hereto or displayed by Landlord to Tenant with respect
to the subject matter thereof, and none thereof shall be used to interpret or
construe this Lease. There are no representations or warranties between the
parties except as expressly set forth in this Lease, and all reliance with

            ----------------------------                                       
shall be determined to be void by any court of competent jurisdiction, then such
determination shall not affect any other provisions of this Lease and all such
other provisions shall remain in full force and effect; and it is the intention
of the parties hereto that if any provision of this Lease is capable of two
constructions, one of which would render the provision void and the other of
which would render the provision valid, then the provision shall have the
meaning which renders it valid.

      29.10 Lease Modification. This Lease shall not be modified or amended in
            -------------------

      29.11 Guarantees. In the event that this Lease shall have been guaranteed,
            -----------                                                         
any such guarantee shall be deemed a material part of the consideration for
Landlord's execution of this Lease. In the event the Guarantor under any such
guarantee is or becomes bankrupt or insolvent, makes an assignment for the
benefit of creditors, or institutes or is the subject of any proceeding under
the Bankruptcy Act or other similar law for the protection of creditors (or, if
the Guarantor is a partnership or consists of more than one (1) person or
entity, if any partner of the partnership or other such person or entity is or
becomes bankrupt or insolvent, institutes any such proceeding, or makes an
assignment for the benefit of creditors), then Landlord shall have the option to
terminate this Lease upon thirty (30) days' written notice unless Tenant, within
such thirty (30) day period, provides Landlord with either (1) a substitute or
additional guarantor satisfactory to Landlord and Landlord's lender, or (2)
adequate assurance of the performance of each and every obligation of Tenant
hereunder, satisfactory to Landlord and Landlord's lender.

      29.12 Lender Approval. Tenant acknowledges and agrees that this Lease is
            ----------------

any other person in connection with this Lease shall be conclusively presumed to
have been paid by Tenant or on Tenant's behalf, unless (i) Landlord has been
given prior written notice to the contrary by Tenant, and (ii) Landlord has
consented to payment of such sums by such person other than Tenant. In no event
shall the foregoing be construed as requiring Landlord to accept any rental
payments or other sums from any person other than Tenant.

      29.15 Obligations. The obligations of this Lease shall run with the land,
            ------------                                                       
and this Lease shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and assigns, except that only the
original Landlord named herein shall be liable for obligations accruing before
the beginning of the Term, and thereafter the original Landlord names herein and
each successive owner of the Premises shall be liable only for obligations
accruing during the period of its ownership.

      29.16 Brokers. Other than none ("Broker"), Tenant hereby warrants and
            --------            ----                                           
represents that it has not employed or dealt with any other broker or finder in
connection with the Lease or the Property. Tenant agrees to defend, indemnify
and hold Landlord harmless from any and all liability Landlord may incur because
of the claim by any broker, other than Broker, that claims to be entitled to a
commission or fee because they have represented Tenant in connection with this
transaction.

      29.17 Time. Time is of the essence of this Lease and each and every
            -----                                                         
provision hereof. All the terms, covenants and conditions contained in this
Lease to be performed by either party, if such party shall consist of more than
one person or organization, shall be deemed to be joint and several, and all
rights and remedies of the parties shall be cumulative and non-exclusive of any
other remedy at law or in equity.

      29.18 Scope of Landlord's Obligation. The obligations of Landlord under
            -------------------------------                                  
this Lease do not constitute personal obligations of the individual entities
which comprise Landlord nor of their respective partners, directors, officers or
shareholders, and Tenant shall look solely to the real estate that is the
subject of this Lease and to no other assets of the entities comprising Landlord
for satisfaction of any liability in respect of this Lease and will not seek
recourse against the individual entities which comprise Landlord nor against
their respective partners, directors, officers or shareholders nor against any
of their personal assets for such satisfaction.

      29.19 Diminution in Light and Air. Any diminution or shutting off of light
            ----------------------------                                        
or air by any structure which may be erected on lands adjacent to or in the
vicinity of the Property shall not affect the Lease, abate any payment owed by
Tenant under the Lease or otherwise impose any liability on Landlord.

      29.20 Confidentiality. This Lease document and the terms of this Lease,
            ----------------                                                 
and the covenants, obligations, and conditions contained in this Lease shall
remain strictly confidential. Tenant agrees to keep such terms, covenants,
obligations and conditions strictly confidential and not to disclose the Base
Rent or any of the economic concessions to any other landlord, tenant,
prospective tenant, or broker. Provided, however, Tenant may provide a copy of
this Lease to a non-party solely in conjunction with Tenant's reasonable and
good faith effort to secure an assignee or sublessee for the Premises.

      29.21 Good Faith: Wherever this Lease grants Landlord or Tenant the right
to take action, exercise discretion, establish rules and regulations or make
allocations or other determinations, Landlord and Tenant shall act reasonably
and in good faith and take no action which might result in the frustration of
the reasonable expectations of a sophisticated Landlord and sophisticated Tenant
concerning the benefits to be enjoyed under this Lease.

      29.22 Conditions for Tenant's Termination. No act or failure to act on the
            ------------------------------------                                
part of Landlord which would entitle Tenant under the terms of this Lease, or by
law, to be relieved of Tenant's obligations hereunder or to terminate this
Lease, shall result in a release or termination of such obligations or a
termination of this Lease unless (a) Tenant shall have first given written
notice of Landlord's act or failure to act to Landlord's First Mortgagee of
record if any, specifying the act or failure to act on the part of Landlord
which could or would give basis to Tenant's rights and (b) such First Mortgagee,
after receipt of such notice, has failed or refused to correct or cure the
condition complained of within a "reasonable time" thereafter; but nothing
contained in this Section 29.22 shall be deemed to impose any obligation on any
such First Mortgagee to correct or cure any condition.

                                PARKING AGREEMENT



So long as the lease dated July 14, 1997 between Zulu Properties Co., Ltd., a
California Corporation ("Landlord"), by and through Total Properties Management
Co., managing agent for the Property ("Landlord's Manager") and Harden & Company
Inc., a California corporation ("Tenant") covering space in the 3460 Wilshire
Blvd., Ste. 407, Los Angeles, CA 90010 property known as Central Plaza (the
"Property") remains in effect, and so long as the Rules and Regulations adopted
by Landlord are not violated, Tenant or persons designated by Tenant, shall have
the right to rent on a month-to-month basis parking spaces for the non-exclusive
parking of six (6) automobiles in the Parking Facilities associated with or
forming a part of the Property. Said parking spaces shall be offered to Tenant
at the building's prevailing parking rates subject to applicable city, state,
and federal taxes and assessments, if any, which amount may be changed from time
to time at Landlord's reasonable discretion. Tenant may validate visitor parking
by such methods as the Landlord or the parking operator may approve at the
validation rate from time to time generally applicable to visitor parking;
provided, however, the right to the parking spaces granted in this Parking
Agreement shall be subject to cancellation by Landlord, in whole or in part, at
any time upon not less than thirty (30) days prior written notice (except where
the Parking Rules and Regulations provide for a shorter notice should Tenant
violate the Parking Rules and Regulations).

A condition of any parking shall be compliance by the driver with Parking Rules
and Regulations, including any sticker or other identification system
established by the parking operator. The following Parking Rules and Regulations
are currently in effect. Landlord reserves the right to modify and/or adopt such
other reasonable and nondiscriminatory Rules and Regulations for the Parking
Facilities as it deems necessary for the operation of the Parking Facilities.
The parking operator may refuse to admit any person who violates the Parking
Rules and Regulations ("Rules") to park in the Parking Facilities, and any
violation of the Rules shall subject the car to removal from the Parking
Facilities. In either of said events the parking operator shall refund a prorata
portion of the current parking rate and the sticker or any other form of
identification shall be returned or caused to be returned by Tenant to the
parking operator.

Landlord expressly disclaims any responsibility for any theft of or vandalism or
damage to any personal property, including without limitation, any motor
vehicle, in, on, or about the Parking Facilities irrespective of cause,
circumstance, or parties involved. As a material inducement to Landlord to allow
Tenant the parking rights set forth herein, Tenant agrees to assume full
responsibility for the foregoing to the extent such relates to Tenant and/or
Tenant's employees, principals, agents, affiliates, and/or invitees, and Tenant
agrees to indemnify, defend and hold harmless Landlord for alt costs, liability
and damages relating to or arising from the foregoing.

The occurrence of the following shall constitute a material default and breach
of the Lease to which this Parking Agreement is attached as Exhibit "F" and
shall entitle Landlord to exercise such remedies as are therein provided, in
addition to any other right or remedy which Landlord may have at law or in
equity by reason of such default or breach:

(a) The failure of Tenant to make any payment required to be made by Tenant
under this Parking Agreement, where such failure continues until the earlier of
(i) five (5) days after the date on which such payment was due, or (ii) three
days after written notice thereof has been given by Landlord to Tenant; or

(b) The failure of Tenant to observe and perform any other provision of this
Parking Agreement to be observed or performed by Tenant, where such failure
continues for five (5) days after written notice thereof by Landlord to Tenant;
provided, however, that any such notice referred to in part (b) hereof shall be
in lieu of and not in addition to any notice required under Section 1161 of the
California Code of Civil procedure.

                          PARKING RULES AND REGULATIONS

1. Parking Facilities hours shall be as posted by management.

2. Cars must be parked entirely within the stall lines painted on the floor.

3. All directional signs and arrows must be observed.

4. The speed limit shall be 5 miles per hour.

     (a) not striped for parking
     (b) aisles

     (e) in reserved spaces, except for the person for whom such space is
         reserved.

6. Parking stickers or any other device or form of identification supplied by
the parking operator shall remain the property of the parking operator. Such
parking identification device must be displayed in the front area of the
interior of the vehicle, or as requested, so that it may be readily observed by
the parking operator's attendants at all times while the vehicle is in the
Parking Facilities, and it may not be mutilated in any manner, and the serial
number of the parking identification device may not be obliterated. Devices are
not transferable and any device in the possession of an unauthorized holder will
be void.

7. The monthly rent for parking space is payable one (1) month in advance and
must be paid prior to the fifth day of each calendar month. Failure to do so

or allowances from the monthly rate will be made for time the customer does not

the first car shall pull all the way to the front of the space leaving room for
a second car to park behind the first car. The driver parking behind the first
car must leave his key in the ignition and the door of his car unlocked. Failure
to do so shall subject the driver of the second car to a $25 fine. Refusal of
the driver to leave his key to the second car when parking tandem shall be cause
for termination of the right to park in the Parking Facilities. The parking
operator, or his employees or agents, shall be authorized to move cars that are
parked in tandem should it be necessary for the operation of the Parking
Facilities. Tenant agrees that all responsibility for damage to cars or the
theft of or from cars is assumed by the driver, and further agrees that he/she
will hold Landlord harmless for any such damages or theft.

must be reported to the parking operator immediately, and a lost or stolen
report must be filed by the customer at that time.

     (a) Any parking identification stickers or devices reported lost or stolen,
found on any unauthorized car will be confiscated and the illegal holder will be
subject to prosecution.

     (b) Lost or stolen stickers or devices found by the purchaser must be
reported to the parking operator immediately.

11. Spaces rented are for the express purpose of parking automobiles and for no
other purpose. Washing, waxing, cleaning or servicing of any vehicle by the
customer and/or his agents is prohibited.

12. The parking operator reserves the right to refuse the sale of monthly
stickers to any tenant or person and/or his agents or representatives who
