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

and incorporated herein as Exhibit "A" ("Premises"), of the project ("Project")
now known as Westwood Terrace, whose address is 1640 Sepulveda Boulevard, Los

ARTICLE 1 - Basic Lease Provisions:
----------------------------------
A.    Term:  Commencement Date:     On the later of (i) February 1, 1996, or
                                    (ii) up to five (5) business days after
                                    substantial completion of the tenant
                                    improvement work defined in Article 9 below
                                    to install Tenant's main "T-Switch";
                                    provided, however, Tenant shall use its best
                                    efforts to install such switch prior to the
                                    expiration of said five (5) day period, and
                                    if Tenant does install said switch prior to
                                    the expiration of such five (5) day period
                                    the Lease shall commence on such earlier
                                    date. Substantial completion shall mean
                                    completion of "the Tenant Improvements"
                                    (defined in Article 9), punch-list items
                                    excluded, in accordance with the approved
                                    plans, and the final inspection by the City
                                    of Los Angeles has occurred. Upon Tenant's
                                    occupancy of the Premises, Landlord and
                                    Tenant agree to execute and deliver a
                                    Commencement Letter in a form substantially
                                    similar to that attached hereto as Exhibit
                                    "C." Tenant shall be allowed access to the
                                    Premises prior to the commencement of the
                                    Lease term (without a charge for rent), to
                                    ensure the Premises are properly furnished
                                    and special leasehold improvements,
                                    equipment, furniture, telephone and
                                    computer/data cabling is properly installed
                                    and operational; provided, Tenant shall not
                                    unreasonably interfere with any tenant
                                    improvement work to be done. If Tenant
                                    interferes with the tenant improvement work
                                    because of such early occupancy, the
                                    Commencement Date shall not be delayed but
                                    shall be started as of the date which would
                                    have occurred but for such Tenant
                                    interference.

ARTICLE 2 - Term
----------------

     The term of this Lease shall commence on the Commencement Date (the
"Commencement Date") as set forth in Article l.A. of the Basic Lease Provisions,
and shall end on the expiration date set forth in Article l.A. of the Basic
Lease Provisions.  If Landlord is unable to deliver possession of the Premises
to Tenant on or before the Commencement Date, Landlord shall not be subject to
any liability for its failure to do so, and such failure shall not affect the
validity of this Lease nor the obligations of Tenant hereunder, but the term
hereof shall commence on the earlier of (a) the day that Landlord gives Tenant
written notice that the Premises are ready for occupancy or (b) on the day that
Tenant first occupies the Premises, and the expiration of the term hereof shall
be extended accordingly.

     In the event that the Substantial Completion of the Premises has not
occurred by the "Outside Date", which shall be July 1, 1996, and as such the
July 1, 1996 date may be extended by the number of days of tenant delays (as
defined below), then the sole remedy of Tenant shall U the right to deliver a
notice to Landlord ("Termination Notice") electing to terminate this Lease
effective upon receipt of the Termination Notice by Landlord ("Effective Date").
The Termination Notice must be delivered by Tenant to Landlord, if at all, not
earlier than the Outside Date and not later than five (5) business days after
the Outside Date.

ARTICLE 3 - Rental
------------------

     (a) BASIC RENTAL. Tenant agrees to pay to Landlord during the term hereof,
at Landlord's office or to such other person or at such other place as directed
from time to time by written notice to Tenant from Landlord, the initial monthly
and annual sums as set forth in Article 1.C of the Basic Lease Provisions,
payable in advance on the first day of each calendar month, without demand,
setoff or deduction, and in the event this Lease commences or the date of
expiration of this Lease occurs other than on the first day or last day of a
calendar month, the rent of such month shall be prorated. Notwithstanding the
foregoing, the first month's rent shall be paid to Landlord in accordance with
Article 1.K. of the Basic Lease provisions. Basic Rental shall be subject to
increase from time to time pursuant to the subsequent provisions this Article 3,
or other articles of this Lease and any Addendum (if applicable) incorporated
herein.

     (b)  INCREASE IN DIRECT COSTS. The term "Base Year" means the calendar year
set forth in Article l.D. of the Basic Lease Provisions. If, in any calendar
year during the term of this Lease, the "direct costs" (as hereinafter defined)
paid or incurred by Landlord shall be higher than the direct costs for the Base
Year, Tenant shall pay an additional sum for such and each subsequent calendar
year equal to the product of the amount set forth in Article 1.E. of the Basic
Lease Provisions multiplied by such increased amount of "direct costs." In the
event either the Premises and/or the Project is expanded or reduced, then
Tenant's proportionate share shall be appropriately adjusted, and as to the
calendar year in which such change occurs, Tenant's proportionate share for such
year shall be determined on the basis of the number of days during that
particular calendar year that such Tenant's proportionate share was in effect.
In the event this Lease shall terminate on any date other than the last day of A
calendar year, the additional sum payable hereunder by Tenant during the
calendar year in which this Lease terminates shall be prorated on the basis of
the relationship which the number of days which have elapsed from the
commencement of said calendar year to and including said date on which this
Lease

                                       3
<PAGE>

terminates bears to three hundred sixty (360). Any and all amounts due and
payable by Tenant pursuant to Article 3(b), (c) and (d) hereof shall be deemed
"Additional Rent" and Landlord shall be entitled to exercise the same rights and
remedies upon default in these payments as Landlord is entitled to exercise with
respect to defaults in monthly Basic Rental payments.

     (c)  DEFINITIONS. As used herein the term "direct costs" shall mean the sum
of the following:

          (i)  "Tax Costs," which shall mean any and all real estate taxes and
other similar charges on real property or improvements, assessments, water and
sewer charges, and all other charges assessed, reassessed or levied upon the
Project and appurtenances thereto and the parking or other facilities thereof,
or the real property (the "Property") thereunder (collectively the "Real
Property") or attributable thereto or on the rents, issues, profits or income
received or derived therefrom which axe assessed, reassessed or levied by the
United States, the state of California or any local government authority or
agency or any political subdivision thereof, and shall include Landlord's
reasonable legal fees, costs and disbursements incurred in connection with
proceedings for reduction of Tax Costs or any part thereof (but only to the
extent Landlord reasonably expects to receive a reduction of Tax Costs);
provided, however, if at any time after the date of this Lease the methods of
taxation now prevailing shall be altered so that in lieu of or as a supplement
to or a substitute for the whole or any part of any Tax Costs, there shall be
assessed, reassessed or levied (a) a tax, assessment, reassessment, levy,
imposition or charge wholly or partially as a net income, capital or franchise
levy or otherwise on the rents, issues, profits or income derived therefrom, or
(b) a tax, assessment, reassessment, levy (including but not limited to any
municipal, state or federal levy), imposition or charge measured by or based in
whole or in part upon the Real Property and imposed upon Landlord, or (c) a
license fee measured by the rent payable under this Lease, then all such taxes,
assessments, reassessments or levies or the part thereof so measured or based,
shall be deemed to be included in the term "direct costs."  Notwithstanding the
foregoing, Tax Costs shall not include excess profits, franchise taxes, gift
taxes, capital stock taxes, inheritance and succession taxes, estate taxes and
federal and state income taxes.  Any increase in Tax Costs as a result of the

any taxes thereon; the cost of all charges for fire and extended coverage,

Base Year was determined); the cost of all building and cleaning supplies and

     (d)  DETERMINATION OF PAYMENT.

          (i) At any time following the end of calendar year 1996, but not more
often than once (excepting therefrom adjusted billings) during each calendar
year, commencing with the present calendar year, Landlord shall furnish to
Tenant a written statement showing in reasonable detail Landlord's direct costs
for the Base Year and for the calendar year preceding the year in which such
statement is furnished, and showing the amount, if any, of any increase or
decrease in the sums due from Tenant for such calendar year.  The failure of
Landlord to so furnish said statement shall not constitute a default by Landlord
hereunder or a waiver of Landlord's right to any adjustment provided for
hereunder.

          (ii) On the monthly rental payment date which next occurs thirty (30)
days after Tenant's receipt of such statement Tenant shall pay to Landlord an
amount equal to the sum of (a) the amount shown in said statement as being due
from Tenant (less any amounts paid by

                                       7
<PAGE>

Tenant on account therefrom during such previous calendar year) and (b) one
twelfth (1/12th) of said amount multiplied by the number of rental payment dates
having elapsed during the current calendar year, to be applied on account of
Tenant's proportionate share of the increase in direct costs for the then
present calendar year. The monthly rental payment then due and subsequent
monthly rental payments during the then current calendar year shall be increased
by one-twelfth (1/12th) of Tenant's Proportionate Share of the increase in
direct costs for the preceding calendar year over the Base Year direct costs. In
the case of the decrease in direct costs, any overpayment by Tenant shall be
credited against the next rent payment falling due.

          (iii)  In the event Tenant disputes Landlord's calculation of any
Additional Rent due hereunder for a given Lease year, Tenant shall, only once
for each lease year, have the right within one hundred eighty (180) days of
receipt of the yearly reconciliation provided to Tenant from Landlord, after
reasonable notice and at reasonable times, to inspect Landlord's accounting
records at Landlord's accounting office and if, after such inspection, Tenant
still disputes such Additional Rent, a certification as to the proper amount
shall be made by a nationally recognized accounting firm (who is paid on an
hourly or flat-fee basis and not a contingency or commission basis) selected by
Tenant and approved by Landlord.  Tenant agrees to pay the cost of such
certification unless it is subsequently determined that Landlord's original
statement was in error to Tenant's disadvantage by more than five percent (5%)
of the direct costs.  As a condition precedent to its exercise of its rights of
dispute aforesaid, Tenant shall timely pay to Landlord all amounts set forth in
the statement which Tenant wishes to dispute.

          No audit may be conducted by Tenant if any other tenant of the Project
has notified Landlord of its intention to perform an audit and timely performs
the same.  If Tenant requests an audit and another tenant of the Project has
previously notified Landlord of its intention to audit, then Landlord agrees to
furnish to Tenant a copy of the results of such other audit.  No audit shall be
conducted if Tenant is in default under any provision of this Lease, including,
but not limited to, timely payment of any amount due pursuant to the actual
statement.  Tenant shall deliver to Landlord a copy of the results of an audit
within fifteen (15) days of its receipt by Tenant.

          If an audit indicates an over-billing, Tenant may submit a claim for
the over-billed amount to Landlord, detailing the nature of the over-billing,
and Landlord shall have sixty (60) days to pay such amount or contest the claim
by giving notice thereof to Tenant, detailing the nature of Landlord's contest
of Tenant's claims.  If Landlord contests the claim, either Landlord or Tenant
may submit the claim to arbitration in accordance with the dispute resolution
procedures set forth by the American Arbitration Association (or similar
successor entity) for such matters.  If the arbitration discloses that the
actual statement is more than five percent (5%) overstated, Landlord shall,
within thirty (30) days of the date of decision by the Arbitrator, pay to Tenant
the amount of any over-billing.  If the Arbitrator determines that the actual
statement is understated, Tenant shall, within thirty (30) days of the date of
the Arbitrator's decision pay to Landlord the amount of the underbilling so
determined.

          Except as provided in this Article 3, Tenant shall keep all
information gained in connection with any audit confidential.  Tenant shall not
disclose any information gained in connection with any audit to third parties
except to those who must receive the information in order to carry out the
purpose of this Article 3, and agree in writing to keep the information

                                       8
<PAGE>

confidential.  Failure to observe the provision of this confidentiality
requirement shall be deemed a material default under the Lease.

          (iv) Landlord shall have the right, prior to the commencement of each
calendar year during the term hereof during which Tenant's obligation may
adjusted under this Article 3, to furnish to Tenant a written estimate showing
in reasonable detail Landlord's estimated direct costs for the next following
calendar year and the amount of Tenant's proportionate share of increase in
direct costs over the Base Year direct costs appropriately prorated on a monthly
basis.  Thereafter, the monthly rent adjustment payments becoming due hereunder
shall be in the amounts set forth in said written estimate.  Neither Landlord's
failure to deliver nor the late delivery of such estimate shall constitute a
default by Landlord hereunder or a waiver of Landlord's right to any rent or
other-adjustment provided for herein.  Within one hundred twenty (120) calendar
days following the close of each calendar year during the term hereof, Landlord
will furnish to Tenant a written statement (the "Reconciliation") showing in
reasonable detail Landlord's actual direct costs for the relevant calendar year,
together with a full statement of any adjustments necessary to reconcile any
sums paid (or credited) hereunder as an estimated amount of Tenant's
Proportionate Share of direct costs during such calendar year with those sums
actually payable and due hereunder for such calendar year as set forth in the
Reconciliation.  If the Reconciliation shows that additional sums are due from
Tenant hereunder, Tenant shall pay such sums to Landlord within thirty (30) days
of receipt of the Reconciliation.  If the Reconciliation shows that a credit is
due Tenant, such credit shall be credited against the next sums becoming due
from Tenant hereunder.  Notwithstanding that the term of this Lease has expired
and Tenant has vacated the Premises, Tenant shall pay to Landlord any additional
sums due Landlord and Landlord shall rebate to Tenant the amount of any credit
due Tenant, as set forth in the Reconciliation for the year in which the Lease
term expired.  Even though the term of this Lease has expired and Tenant has
vacated the Premises, when the final determination is made of Tenant's share of
Tax Costs and operating Costs for the year in which this Lease terminated,
Tenant shall pay any increase due over the estimated amounts paid.  The terms of
this Article 3(d)(iv) shall survive the expiration or earlier termination of the
Lease Term (including any and all option periods, if applicable).

ARTICLE 4 - Security Deposit
----------------------------

     Tenant has deposited with Landlord the sum set forth in Article 1.F. of the
Basic Lease Provisions as security for the full and faithful performance of
every provision of this Lease to be performed by Tenant.  If Tenant breaches any
provision of this Lease, including but not limited to that payment of rent,
Landlord may, following the expiration of any grace or n ice period, use all or
any part of this security deposit for the payment of any rent or any other sums
in 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 five (5) days after written
demand therefor, deposit cash with Landlord in an amount sufficient to restore
the security deposit to amount then required in Article 1.F. of the Basic Lease
Provisions.  Tenant agrees that Landlord shall not be required to keep this
security deposit in trust, segregate it or keep it separate from Landlord's
general funds but Landlord may commingle the security deposit with its general
funds and Tenant shall not be entitled to interest on such deposit.  At the
expiration of the Lease term, and provided there exists no default, following
the expiration of any grace or notice period, by Tenant hereunder, the security
deposit or any balance thereof shall

                                       9
<PAGE>

be returned to Tenant (or, at Landlord's option, to Tenant's assignee), provided
that subsequent to the expiration of this Lease, Landlord may retain from said
security deposit (a) any and all amounts permitted by California Civil Code
(S)1950.7 or any successor or replacement statute; but not limited to this
section.

ARTICLE 5 - Holding Over
------------------------

     Should Tenant, without Landlord's written consent, hold over after
termination of this Lease, Tenant shall become a tenant from month to month,
only upon each and all of the terms herein provided as may be applicable to a
mouth-to-month tenancy, and any such holding over shall not constitute an
extension of this Lease.  During the first three (3) months of such holding
over, Tenant shall pay on the first of each month, Monthly Basic Rental, all
direct costs, and all other and additional rent due hereunder at the rate of one
hundred twenty-five percent (25%) for such amounts in effect for the last month
of the Lease term.  After the first three (3) months of such holding-over
period, Tenant shall pay Monthly Basic Rental at the rate of one hundred fifty
percent (150%) of the Monthly Basic Rental in effect for the last month of the
term of this Lease, in addition to, and not in lieu of, all other payments
required to be made by Tenant hereunder, including but not limited to, Tenant's
Proportionate Share of any increase in direct costs.  If Tenant fails to
surrender the Premises upon the expiration or termination of this Lease, Tenant
hereby indemnifies and agrees to hold Landlord and any real estate broker and
agent harmless from all costs, loss, expense or liability, including without
limitation, costs, real estate brokers claims and attorney's fees.

ARTICLE 6 - Personal Property Taxes
-----------------------------------

     Tenant shall pay, prior to delinquency, all taxes assessed against or
levied upon fixtures, furnishings, equipment and all other personal property of
Tenant located in the Premises.  In the event any or all of Tenant's fixtures,
furnishings, equipment and other personal property shall be assessed and taxed
with property of Landlord, Tenant shall pay to Landlord its share of such taxes
within ten (10) days after delivery to Tenant by Landlord of a statement in
writing setting forth the amount of such taxes applicable to Tenant's property.
Tenant shall pay directly to the party or entity entitled thereto all business
license fees, gross receipts taxes and similar taxes and impositions which may
from time to time be assessed against or levied upon Tenant, as and when the
same become due and before delinquency.  Notwithstanding anything to the
contrary contained herein, any sums payable by Tenant under this Article 6 shall
not be included in the computation of "Tax Costs."

ARTICLE 7 - Use
---------------

     Tenant shall use and occupy the Premises only for the use set forth in
Article 1.G. of the Basic Lease Provisions and shall not use or occupy the
Premises or permit the same to be used or occupied for any other purpose without
the prior written consent of Landlord, which Landlord consent may be given or
withheld in its sole and absolute discretion, and Tenant agrees that it will use
the Premises in such a manner so as not to unreasonably interfere with or
infringe the rights of other tenants in the Project.  Tenant shall, at its sole
cost and expense, promptly comply with all laws, statutes, ordinances and
governmental regulations or requirements now in force or which may hereafter be
in force relating to or affecting (i) the manner of use or occupancy of the

                                      10
<PAGE>

Premises or the Project, and (ii) improvements installed or constructed in the
Premises by or for the benefit of Tenant.  Tenant shall not do or permit to be
dome anything which would invalidate or increase the cost of any fire and
extended coverage insurance policy covering the Project and/or the property
located therein and Tenant shall comply with all rules, orders, regulations and
requirements of any organization which sets out standards, requirements or
recommendations commonly referred to by major fire insurance underwriters.
Tenant shall promptly upon demand reimburse Landlord for any additional premium
charges for any such insurance policy assessed or increased by reason of
Tenant's failure to comply with the provisions of this Article.

ARTICLE 8 - Condition of Premises
---------------------------------

     Tenant hereby agrees that the Premises shall be taken "as is", and Tenant
hereby agrees and warrants that it has inspected the condition of the visible
portion of the Premises and the suitability of same for Tenant's purposes, and
Tenant does hereby waive and disclaim any objection to, cause action based upon,
or claim that its obligations hereunder should be reduced or limited because of
the condition of the visible portions of the Premises or the Project or the
suitability of same for Tenant's purposes.  The foregoing sentence
notwithstanding, Landlord agrees to bear the cost for any latent structural
defects in the Premises which are discovered by Tenant (and written notice is
given to Landlord) during the first year of the Lease term only except to the
extent set forth in this Lease, Tenant acknowledges that neither Landlord nor
any agent nor any employee of Landlord has made any representations or warranty
with respect to the Premises or the Project or with respect to the suitability
of either for the conduct of Tenant's business.  The taking of possession of the
Premises by Tenant shall conclusively establish that the Premises and the
Project were at such time in satisfactory condition, subject to punch list items
if applicable.  Tenant hereby waives Sections 1941 and 1942 of the Civil Code of
California or any successor provision of law.

     Landlord reserves the right from time to time: (i) to install, use,
maintain, repair, replace and relocate for service to the Premises and/or other
parts of the Project pipes, ducts, conduits, wires, appurtenant fixtures, and
mechanical systems, wherever located in the Premises or the Project, (ii) to
alter, close or relocate any facility in the Premises or the Common Areas or
otherwise conduct any of the above activities for the purpose of complying with
a general plan for fire/life safety for the Project or otherwise and (iii) to
comply with any federal, state or local law, rule or order with respect thereto
or the regulation thereof not currently in effect.  Landlord shall attempt to
perform any such work with the least inconvenience to Tenant as possible
(including the performance of same during after hours), but in no event shall
Tenant be permitted to withhold or reduce Basic Rent or other charges due
hereunder as a result of same or otherwise make claim against Landlord for
interruption or interference with Tenant's business and/or operations or for any
other reason whatsoever unless the work materially interferes with the operation
of Tenant's business.

     Landlord agrees, at its sole cost and expense, to thoroughly clean the
Premises immediately prior to Tenant's occupancy and immediately after Tenant
has moved in and "set-up" the Premises.

ARTICLE 9 - Repairs and Alterations
-----------------------------------

     Tenant shall keep the Premises in good condition and repair, except for
damage caused by ordinary wear and tear, or caused by Landlord, its agents,
representatives, employees or contractors or otherwise beyond the reasonable
control of Tenant (provided, however, such exclusion shall not exclude damage
caused by Tenant or Tenant's employees, invitees, agents and the like).  All
damage or injury to the Premises or the Project caused by the act or negligence
of Tenant, its employees, agents or visitors, guests, invitees or licensees or
by the use of the Premises shall be promptly repaired by Tenant, at its sole
cost and expense (except to the extent Landlord has responsibility for same
under this Lease.), to the satisfaction of Landlord; provided, however, that for
damage to the Project, Landlord shall have the right (but not the obligation) to
select the contractor and oversee all such repairs.  Landlord may make any
repairs which are not promptly made by Tenant after Tenant's receipt of written
notice and the reasonable opportunity of Tenant to make said repair within five
(5) business days from receipt of said written notice, and charge Tenant for the
cost thereof, which cost shall be paid by Tenant within five (5) days from
invoice from Landlord.  Tenant shall be responsible for the design and function
of all nonstandard improvements of the Premises, whether or not installed by
Landlord at Tenant's request.  Tenant waives all rights to make repairs at the
expense of Landlord, or to deduct the cost thereof from the rent.  Tenant shall
make no alterations, changes or additions in or to the Premises without
Landlord's prior written consent, and then only by contractors or mechanics
approved by Landlord in writing and upon the approval by Landlord in writing of
fully detailed and dimensioned plans and specifications pertaining to the work
in question, to be prepared and submitted by Tenant at its sole cost and
expense.  Tenant shall at its sole cost and expense obtain all necessary
approvals and permits pertaining to any work approved by Landlord.  If Landlord,
in approving any work, specifies a reasonable commencement date therefor, Tenant
shall not commence any work prior to such date.  Tenant hereby indemnifies and
agrees to hold Landlord free and harmless from all liens and claims of lien, and
all other liability, claims and demands arising out of any work done or material
supplied to the Premises by or at the request of Tenant.  If permitted
alterations, changes, or additions are made, they shall be made at Tenant's sole
cost and expense and shall be and become the property of Landlord, except that
Landlord may, by written notice to Tenant given at the time of approval of such
work, require Tenant it Tenant's expense to remove all partitions, counters,
i and the like installed by Tenant (excluding the Tenant Improvements as
defined below), and to repair any damages to the Premises caused by such
removal.  With regard to repairs, alterations or any other work (excluding the
Tenant Improvements) arising from or related to this Article 9 which Tenant
requests Landlord to complete, Landlord shall be entitled to receive an
administrative/supervision fee of fifteen percent (15%) of the total cost of all
(i) work performed; (ii) materials, plans and drawings furnished; and (iii) all
other costs and expenses related to such repairs, alterations or other work.
below, Tenant shall also pay for any required metering system for such unit(s)
and shall pay for any and all utility charges to operate the unit(s).

     Notwithstanding anything to the contrary contained in this Lease, the
contractor(s) and subcontractors constructing the Tenant Improvements shall
receive free on-site parking during construction of the Tenant Improvements, and
Tenant shall not be charged for the use of freight elevators, loading docks,
utilities or temporary HVAC during the construction of the Tenant Improvements.

ARTICLE 10 - Liens
------------------

     Tenant shall keep the Premises and the Project free from any mechanics'
liens, vendors liens or any other liens arising out of any work performed,
materials furnished or obligations incurred by Tenant, and agrees to defend,
indemnify and hold harmless Landlord from and against any such lien or claim or
action thereon, together with costs of suit and reasonable attorneys, fees
incurred by Landlord in connection with any such claim or action.  Before
commencing any work of alteration, addition or improvement (other than the
Tenant Improvements) to the Premises, Tenant shall give Landlord at least ten
(10) business days' written notice of the proposed commencement of such work (to
afford Landlord an opportunity to post appropriate notices of non-
responsibility).  In the event that there shall be recorded against the Premises
or the Project or the property of which the Premises is a part any claim or lien
arising out of any such work performed, materials furnished or obligations
incurred by Tenant and such claim or lien shall not be removed or discharged
within ten (10) days of filing, Landlord shall have the right but not the
obligation to pay and discharge said lien without regard to whether such lien
shall be lawful or correct or to require that Tenant deposit with Landlord in
cash, lawful money of the United States, one hundred fifty percent (150%) of the
amount of such claim, which sum may be retained by Landlord until such claim
shall have been removed of record or until judgment shall have been rendered on
such claim and such judgment shall have become final, at which time Landlord
shall have the right to apply such deposit in discharge of the judgment on said
claim and any costs, including attorneys' fees incurred by Landlord, and shall
remit the balance thereof to Tenant.

     (a)  Landlord agrees to furnish to the Premises, at a cost to be included
in Operating Costs, from 8:00 a.m. to 6:00 p.m. Mondays through Fridays and 9:00
a.m. to 1:00 p.m. on Saturdays, excepting local and national holidays, air
conditioning and heat, electric current for normal lighting and fractional
horsepower for office machines, elevator service and water on the same floor as
the Premises, for lavatory and drinking purposes, all in such reasonable
quantities as in the judgment of Landlord is reasonably necessary for the
comfortable occupancy of the Premises and otherwise consistent with the amounts
furnished by landlords of similar office buildings in West Los Angeles.
Janitorial and maintenance services shall be furnished five (5) days a week,
excepting local and national holidays. Tenant shall comply with all non-
discriminatory rules and regulations which Landlord may reasonable establish for
the proper functioning and protection of the common area air conditioning,
heating, elevator, electrical intrabuilding network cable and plumbing systems.
Landlord shall enforce said rules and regulations on a non-discriminatory basis.
Landlord shall not be liable for, and there shall be no rent abatement as a
result of, any stoppage, reduction or interruption of any such services caused
by governmental rules, regulations or ordinances, riot, strike, labor disputes,
breakdowns, accidents, necessary repairs or other cause. Except as specifically
provided in this Article 11, Tenant agrees to pay for all utilities and other
services utilized by Tenant for all overtime or additional building services
furnished to Tenant not uniformly furnished to all tenants of the Project at
Landlord's actual expense.

     (b)  Tenant will not, without the prior written consent of Landlord, use
any apparatus or device in the Premises, including without limitation electronic
data processing machines,

                                      13
<PAGE>

computer or video equipment or other machines or equipment, using current in
excess of 110 volts, which will in any way increase the amount of electricity or
water usually furnished or supplied for use of the Premises as general office
space; nor connect any apparatus, machine or device with water pipes or electric
current (except through existing electrical outlets in the Premises), for the
purpose of using electric current or water. Nothing contained in this subsection
(b) is intended to restrict Tenant from using equipment and other machines which
are deemed to be standard in first-class office buildings in West Los Angeles.

     (c)  If Tenant shall require electric current in excess of that which
Landlord is obligated to furnish under Article 11(a) and (b) above, Tenant shall
first obtain the written consent of Landlord, which Landlord may refuse in its
reasonable discretion, to the use thereof and Landlord may cause an electric
current meter to be installed in the Premises to measure the amount of electric
current consumed for any such other use.  The cost of any such meter and of
installation, maintenance and repair thereof shall be paid for by Tenant so long
as such consumption by Tenant is in excess of that uniformly furnished to all
tenants at Landlord's expense, and Tenant agrees to pay to Landlord, promptly
upon demand therefor by Landlord, for all such excess electric current consumed
by any such use as shown by said meter at the rates charged for such service by
the City in which the Project is located or the local Public Utility, as the
case may be, furnishing the same, plus any additional expense incurred by
Landlord in keeping account of the electric current so consumed.

     (d)  If any lights, machines or equipment (including but not limited to
computers) are used by Tenant in the Premises in amounts beyond the standard
found in first-class office buildings in West Los Angeles and which materially
affect the temperature otherwise maintained by the air conditioning system, or
generate substantially more heat in the Premises than would be generated by the
building standard lights and usual fractional horsepower office equipment,
Landlord shall have the right to install any machinery and equipment which
Landlord reasonably deems necessary to restore temperature balance, including
but not limited to modifications to the standard air conditioning equipment, and
the cost thereof, including the cost of installation and any additional cost of
operation and maintenance occasioned thereby, shall be paid by Tenant to
Landlord upon demand by Landlord.  Landlord shall not be liable under any
circumstances for loss of or injury to properly, however occurring, through or
in connection with or incidental to failure to furnish any of the foregoing,
[unless such failure was within Landlord's actual control to prevent.]

     (e)  If Tenant requires heating, ventilation and/or air conditioning during
times other than the times provided in Article 11(a) above, Tenant shall give
Landlord such advance notice as Landlord shall reasonably require and shall pay
Landlord's actual cost for the use of such equipment with a two (2) hour minimum
provided, however, the cost for the use f such equipment shall not exceed,
during the Lease term, Sixty-Five Dollars ($65.00) for each hour.

     (f)  Landlord, at its sole cost and expense, shall hire a security service
company for the Project, which company shall also provide after-hours escort
service to the Project's parking structure for Tenant's employees and visitors.
Landlord makes no representations as to the type and level of security or
quality of the company's employees.  Tenant specifically agrees that the
security is for the Project and is not a full-time service to guard the parking
structure or the Premises.

                                      14
<PAGE>

     (g)  In the event that Tenant is prevented from using the Premises or any
portion thereof as a result of any failure of Landlord to provide utilities,
services or access to the Premises or the Project, or there exists a hazardous
material in the Premises (not brought into the Premises by Tenant or any party
under Tenant's control, including employees, invitees, customers and the like)
which by law prevents Tenant from using the Premises, then Tenant shall promptly
give Landlord notice thereof ("Tenant's Notice").  Notwithstanding anything to
the contrary contained in this Lease, in the event that Tenant prevented from
using the Premises or any portion thereof as a result of such a failure for a
period of five (5) consecutive business days following the date Landlord
receives Tenant's Notice ("Notice Date"), all of Tenant's rents (and escalations
thereto) shall be abated or reduced, as the case may be, in the proportion that
the rentable area of the portion of the Premises that the Tenant is prevented
from using bears to the total rentable area of the Premises, during the period
after the Notice Date that Tenant is prevented from conducting its business from
the Premises or portion of the Premises.  However, in the event that Tenant is
prevented from conducting its business in any portion of the Premises and the
remaining portion of the Premises is not sufficient to allow Tenant to
efficiently conduct its business therein, and if Tenant does not conduct its
business-from such remaining portion, then all of the rents for the entire
Premises shall be abated during said period.  Provided, however, that if Tenant
is prevented from using the Premises and Tenant reoccupies and conducts its
business from any portion of the Premises during such period, the rents
allocable to such reoccupied portion, based upon the proportion which the
rentable area of such reoccupied portion of the Premises bears to the total
rentable area of the Premises, shall be payable by Tenant from the date such
business operation commences.

ARTICLE 12 - Rights of Landlord
-------------------------------

     Landlord and its agents shall have the right to enter the Premises at all
reasonable times for the purpose of cleaning the Premises, examining or
inspecting the same, serving or posting and keeping posted thereon notice's as
provided by law, or which Landlord deems necessary for the protection of
Landlord or the Property, showing the same to prospective tenants or purchasers
of the Project, in the case of an emergency, and for making such alterations,
repairs, improvements or additions to the Premises or to the Project as Landlord
may deem necessary or desirable.  If Tenant shall not be personally present to
open and permit an entry into the Premises at any time when such an entry by
Landlord is necessary or permitted hereunder, Landlord may enter by means of a
master key or may enter forcibly, only in the case of an emergency, without
liability to Tenant except for any failure to exercise due care for Tenant's
property, and without-affecting this Lease.  Any such entry by Landlord shall be
conducted at such times as is reasonably necessary under the circumstances to
cause the least amount of disruption to Tenant's business.

ARTICLE 13 - Indemnity; Exemption of Landlord from Liability
------------------------------------------------------------

     (a) INDEMNITY.  Tenant shall indemnify, defend and hold Landlord harmless
from any and all claims arising from Tenant's use of the Premises or the Project
(including Tenant's Signage rights set forth in Article 34) or from the conduct
of its business or from any activity, work or thing which may be permitted or
suffered by Tenant in or about the Premises or the Project and shall further
indemnify, defend and hold Landlord harmless from and against any and all claims
arising from any breach or default in the performance of any obligation on

                                      15
<PAGE>

Tenant's part to be performed under this Lease or arising from any negligence of
Tenant or any of its agents, contractors, employees or invitees, patrons or
customers in or about the Project and from any and all costs, attorneys' fees,
expenses and liabilities incurred in the defense of any claim or any action or
proceeding brought thereon, including negotiations in connection therewith.
Tenant hereby assumes all risk of damage to property or injury to persons in or
about the Premises from any cause, and Tenant hereby waives all claims in
respect thereof against Landlord, excepting where the damage is caused by the
gross negligence or willful misconduct of Landlord and is not covered by
Tenant's insurance.

     (b) EXEMPTION OF LANDLORD FROM LIABILITY.  Landlord shall not be liable for
injury to Tenant's business, or loss of income therefrom, or for damage that may
be sustained by the person, goods, wares, merchandise or property of Tenant, its
employees, invitees, customers, agents, or contractors, or any other person in,
on or about the Premises directly or indirectly caused by or resulting from
fire, steam, electricity, gas, water, or rain which may leak or flow from or
into any part of the Premises, or from the breakage , leakage, obstruction or
other defects of the pipes, sprinklers, wires, appliances, plumbing, air
conditioning, light fixtures, or mechanical or electrical systems or from
intrabuilding network cable, whether such damage or injury results from
conditions arising upon the Premises or upon other portions of the Project or
from other sources or places and regardless of whether the cause of such damage
or injury or the means or repairing the same is inaccessible to Tenant, except
in connection with damage or injury resulting from the gross negligence or
willful misconduct of Landlord, or its authorized agents.  Landlord shall not be
liable to Tenant for any damages arising from any act or neglect of any other
tenant of the building.

ARTICLE 14 - Insurance
----------------------

     (a) TENANT'S INSURANCE.  Tenant, shall at all times during the term of this
Lease, and at its own cost and expense, procure and continue in force the
following insurance coverage: (i) Commercial General Liability Insurance with a
combined single limit for bodily injury and property damages of not less than
One Million Dollars ($1,000,000) per occurrence and Two Million Dollars
($2,000,000) in the annual aggregate, including products liability coverage if
applicable, covering the insuring provisions of this Lease and the performance
of Tenant of the indemnity and exemption of Landlord from liability agreements
set forth in Article 13 hereof; (ii) a policy of standard fire, extended
coverage and special extended coverage insurance (all risks), including a
vandalism and malicious mischief endorsement, sprinkler leakage coverage and
earthquake sprinkler leakage where sprinklers are provided in an amount equal to
the full replacement value new without deduction for depreciation of all
equipment, fixtures and furniture installed by or at the expense of Tenant; and
(iii) insurance for all telecommunications equipment and intrabuilding network
for which Tenant is responsible.  Tenant shall carry and maintain during the
entire Lease term (including any option periods, if applicable), at Tenant's
sole cost and expense, increased amounts of the insurance required to be carried
by Tenant pursuant to this Article 14 and such other reasonable types of
insurance coverage and in such reasonable amounts covering the Premises and
Tenant's operations therein, as may be reasonably required by Landlord, so long
as such requirement is consistent with the requirements of other landlords of
first-class office buildings in West Los Angeles, or required by Landlord's
lender.

                                      16
<PAGE>

     (b) FORM OF POLICIES.  The aforementioned minimum limits of policies and
Tenant's procurement and maintenance thereof shall in no event limit the
liability of Tenant hereunder.  Such insurance shall name Landlord and such
other persons or firms with insurable interests, as Landlord specifies from time
to time, as additional insureds' with an appropriate endorsement to the
policy(s) and shall be with companies having a rating of not less than A-VIII in
Best's Insurance Guide.  Tenant shall furnish to Landlord, from the insurance
companies, or cause the insurance companies to furnish, certificates of
coverage.  No such policy shall be cancelable or subject to reduction of
coverage or other modification or cancellation except after thirty (30) days
prior written notice to Landlord by the insurer.  All such policies shall be
endorsed to agree that Tenant's policy is primary and that any insurance covered
by Landlord is excess and not contributing with any Tenant insurance requirement
hereunder.  Tenant shall, at least twenty (20) days prior to the expiration of
such policies, furnish Landlord with renewals or binders.  Tenant agrees that if
Tenant does not take out and maintain such insurance or furnish Landlord with
renewals or binders, Landlord may (but shall not be required to) procure said
insurance on Tenant's behalf and charge Tenant the cost thereof, which amount
shall be payable by Tenant upon demand with interest from the date such sums are
extended.  Tenant shall have the right to provide such insurance coverage,
pursuant to blanket policies obtained by Tenant, provided such blanket policies
expressly afford coverage to the Premises and to Tenant as required by this
Lease.

     (c) LANDLORD'S INSURANCE.  Landlord shall, as a cost to be included in
Operating Costs, procure and maintain at all times during the term of this
Lease, a policy or policies of insurance covering loss or damage to the Project
(including the Tenant Improvements, but excluding Tenant's personal property,
equipment, fixtures, and the like) in the amount of the full replacement costs
without deduction for depreciation thereof (exclusive of Tenant's trade
fixtures, inventory, personal property and equipment); providing protection
against all perils included within the classification of fire and extended
coverage, vandalism coverage and malicious mischief, sprinkler leakage, water
damage, and special extended coverage on building.  Additionally, Landlord may
(but shall not be required to) carry: (i Bodily Injury and Property Damage
Liability Insurance and/or Excess Liability Coverage insurance; and (ii)
Earthquake and/or Flood Damage insurance; and (iii) Rental Income Insurance at
its election or if required by its lender from time to time during the term
hereof, in such amounts and with such limits as Landlord or its lender may deem
appropriate.  The costs of such insurance shall be included in operating Costs.

     (d) WAIVER OF SUBROGATION.  Tenant releases Landlord (and its respective
authorized representatives) and Landlord releases Tenant (and its respective
authorized representatives) from any claims for damage to any person or the
Premises, and to the fixtures, personal property, improvements, and alterations
of either Landlord or Tenant, in or on the Premises, and the Project, that are
caused by or result from risks insured against under any insurance policies
carried by either Tenant or Landlord and in force at the time of any such
damage.

     (e) COMPLIANCE WITH LAW.  Tenant agrees that it will not, at any time,
during the term of this Lease, carry any stock of goods or do anything in or
about the Premises that will in any way tend to increase the insurance rates
upon the Project.  Tenant agrees to pay Landlord forthwith upon demand the
amount of any increase in premiums for insurance against loss by fire

                                      17
<PAGE>

that may be charged during the term of this Lease on the amount of insurance to
be carried by Landlord on the Project resulting from the foregoing, or from
Tenant doing any act in or about said Premises that does so increase the
insurance rates, whether or not Landlord shall have consented to such act on the
part of Tenant. If Tenant installs upon the Premises any electrical equipment
which constitutes an overload of electrical lines of the Premises, Tenant shall
at its own cost and expense in accordance with all other Lease provisions, and
subject to the provisions of Article 9, 10 and 11, hereof, make whatever changes
are necessary to comply with requirements of the insurance underwriters and any
governmental authority having Jurisdiction thereover, but nothing herein
contained shall be deemed to constitute Landlord's consent to such overloading.
Tenant shall, at its own expense, comply with all requirements of the insurance
authority having jurisdiction over the Project necessary for the maintenance of
reasonable fire and extended coverage insurance for the Premises, including
without limitation thereto, the installation of fire extinguishers or an
automatic dry chemical extinguishing system.

ARTICLE 15 - Assignment and Subletting
--------------------------------------

     Tenant shall have no power to, either voluntarily, involuntarily, by
operation of law or otherwise, sell, assign, transfer or hypothecate this Lease,
or sublet the Premises or any part thereof, or permit the Premises or any part
thereof to be used or occupied by anyone other than Tenant or Tenant's employees
without the prior written consent of Landlord which consent shall not be
unreasonably withheld.  If Tenant is a corporation, unincorporated association
or partnership, the sale, assignment, transfer or hypothecation of any class of
stock or other ownership interest in such corporation, association or
partnership in excess of twenty-five percent (25%) in the aggregate ("Internal
Transfer") shall meet the transfer provisions of Subsection (g) below, but
Tenant shall not be required to pay any of the review, processing or attorney's
fees set forth below.  The foregoing notwithstanding, Landlord shall have no
right of consent or approval, of any kind, in connection with the issuance,
sale, transfer, assignment, or hypothecation of securities and/or assets by
Tenant for which filings are required to be made with federal or state agencies,
including by way of illustration, but not limitation, the Securities and
Exchange commission or the California Commissioner of Corporations.  Subject to
the foregoing, Tenant may transfer its interest pursuant to this Lease only upon
the following express conditions:

     (a)  That the proposed transferee shall be subject to the prior written
consent of Landlord, which consent will not be unreasonably withheld (it being
agreed that if Landlord does not respond within ten (10) business days from a
written request for sublease or assignment, such refusal to respond shall be
deemed an approval by Landlord to such assignment or sublease) but, without
limiting the generality of the foregoing, it shall be reasonable for Landlord to
deny such consent if:

          (i) The use to be made of the Premises by the proposed transferee is.
(a) not generally consistent with the character and mature of all other
tenancies in the Project, or (b) a use which conflicts with any so-called
"exclusive" then in favor of, or for any use which is the same as that stated in
any percentage Lease to, another tenant of the Project or any of Landlord's then
buildings which are in the same complex as the Project, or (c) a use which would
be prohibited by any other portion of this Lease (including but not limited to
any Rules and Regulations then in effect); or

                                      18
<PAGE>

          (ii) The financial responsibility of the proposed transferee is not
reasonably satisfactory to Landlord or in any event not at least equal to those
which were possessed by Tenant as of the date of execution of this Lease;

     (b)  That Tenant shall pay to Landlord Landlord's then standard processing
fee, review fee and attorneys' fees up to the sum of One Thousand Dollars
($1,000.00);

     (c)  That the proposed transferee shall execute an agreement pursuant to
which it shall agree to perform faithfully and be bound by all of the terms,
covenants, conditions, provisions and agreements of this Lease (provided,
however, this Subparagraph (c) shall not be deemed to apply to the economic
business terms of the transfer between Tenant and such transferee);

     (d)  That an executed duplicate original of said assignment and assumption
agreement or other transfer on Landlord's then standard form, shall be delivered
to Landlord within five days after the execution thereof, and that such transfer
shall not be binding upon Landlord until the delivery thereof to Landlord and
the execution and delivery of Landlord's consent thereto.  It shall be a
condition to Landlord's consent to any subleasing, assignment or other transfer
of part or all of Tenant's interest in the Premises (hereinafter referred to as
a "Transfer") that (i) upon Landlord's consent to any Transfer, Tenant shall pay
and continue to pay one-half (1/2) of any "Transfer Premium" (defined below),
received by Tenant from the transferee; provided, however, Tenant shall have the
right to sublease up to twenty percent (20%) of the Premises to individual users
without sharing of the Transfer Premium; (ii) any Sublessee of part or all of
Tenant's interest in the Premises shall agree that in the event Landlord gives
such sublessee notice that Tenant is in default under this Lease following the
expiration of any grace or cure period, such sublessee shall thereafter make all
sublease or other payments directly to Landlord, which will be received by
Landlord without any liability whether to honor the sublease or otherwise
(except to credit such payments against sums due under this Lease), and any
sublessee shall agree to attorn to Landlord or its successors and assigns at
their request should this Lease be terminated for any reason, except that in no
event shall Landlord or its successors or assigns be obligated to accept such
attornment, (iii) any such Transfer and consent shall be effected on reasonable
forms, supplied or approved by Landlord and/or its legal counsel; and (iv)
Landlord may require that Tenant not then be in default following the expiration
of any grace or cure period hereunder in any respect.  "Transfer Premium" shall
mean all rent, additional rent or other consideration payable by a transferee in
connection with a Transfer in excess of the rent and Additional Rent payable by
Tenant under this Lease during the term of the Transfer and if such Transfer is
less than all of the Premises, the Transfer Premium shall be calculated on a
rentable square foot basis.  The Transfer Premium shall be calculated after
deducting the reasonable expenses incurred by Tenant for any reasonable Tenant
improvements (reasonably approved by Landlord), legal fees, rent concessions and
brokerage commissions in connection with the Transfer.  "Transfer Premium" shall
also include, but not be limited to, key money, bonus money or other cash
consideration paid by a transferee to Tenant in connection with such Transfer,
and any payment in excess of fair market value for services rendered by Tenant
to transferee or for assets, fixtures, inventory, equipment, or furniture
transferred by Tenant to transferee in connection with such Transfer.  If
Landlord consents to a requested assignment or sublease, Tenant hereby agrees
that (i) it shall thereupon be deemed, automatically and irrevocably to have
assigned to Landlord as additional security for the performance and observance
of Tenant's obligations and covenants under this Lease, all rent or other sums
received or to be received by

                                      19
<PAGE>

Tenant in connection therewith and (ii) Landlord as assignee and as attorney-in-
fact of Tenant, or a receiver for Tenant whether or not appointed on Landlord's
application may collect such rent or other sums and apply the same toward
Tenant's obligations under this Lease. Notwithstanding the foregoing, Tenant
shall have the right to collect such rent and other sums unless and until Tenant
commits any act of default hereunder following the expiration of any grace or
cure period. Tenant hereby agrees and acknowledges that the above conditions
imposed upon the granting of Landlord's consent to any proposed Transfer by
Tenant are reasonable. Any sale assignment, hypothecation, transfer or
subletting of this Lease which is not in compliance with the provisions of this
Article 15 shall be void. In no event shall the consent by Landlord to an
assignment or subletting be construed as relieving Tenant, any assignee, or
sublessee from obtaining the express written consent of Landlord to any further
assignment or subletting, or as releasing Tenant from any liability or
obligation hereunder whether or not then accrued and Tenant shall continue to be
fully liable therefor. No collection or acceptance of rent by Landlord from any
person other than Tenant shall be deemed a waiver of any provision of this
Article 15 on the acceptance of any assignee or subtenant hereunder, or a
release of Tenant (or of any successor of Tenant or any subtenant holding
theretofore or thereafter accruing). Notwithstanding anything to the contrary in
this Lease, if Tenant or any proposed transferee claims that Landlord his
unreasonably withheld or delayed its consent under this Article 15 or otherwise
has breached or acted unreasonably under this Article 15, their sole remedies
shall be a declaratory judgment and an injunction for the relief sought without
any monetary damages, and Tenant hereby waives all other remedies, including,
without limitation, any right at law or equity to terminate this Lease, on its
own behalf and, to the extent permitted under all applicable laws, on behalf of
the proposed transferee;

     (e)  Tenant shall not enter into any sublease or assignment in which any of
the following is applicable:

          (i) The determination of the amount of rent is expressed in whole or
in part as a percentage of the income or profits derived by the tenant or
subtenant or assignee from the space Leased (other than an amount based on a
fixed percentage or percentages of gross receipts or gross sales);

     (f)  In any sublease or assignment in which the amount of rent is
determined in whole or in part by reference to the gross sales or receipts of
the subtenant or assignee such sublease or assignment shall contain a provision
which prohibits subleasing or assigning or if subleasing or assigning is
permitted it shall prohibit the tenant or any successor in interest from
subleasing all or any portion of its Leasehold interest for an amount of rent
determined in whole or in part from the income or profits derived by any person
from such interest (other than an amount based in a fixed percentage or
percentages of receipts or sales); provided, however, Tenant shall have the
right to sublease up to twenty percent (20%) of the Premises to individual users
without sharing of the Transfer Premium.

     (g)  Notwithstanding anything to the contrary contained in this Article 15,
(i) an internal Transfer, (it) an assignment or subletting of all or a portion
of the Premises to an affiliate of Tenant (an entity which is controlled by,
controls, or is under common control with, Tenant) ("Permitted Transferees"), or
a subletting or assignment of all of the premises to a purchaser of all or
substantially all of the assets of Tenant or a Permitted Transferee, or (iii) a
transfer, by law

                                      20
<PAGE>

or otherwise, in connection with the merger, consolidation or other corporate
reorganization of Tenant or a Permitted Transferee, shall not be deemed a
Transfer requiring payment of a Transfer Premium under this Article 15, but
Tenant shall still be required to obtain Landlord's written consent and approval
of such transfer; provided, however, Landlord shall only be able to disapprove
of such transfer under 15(a)(i) above, or if the transfer would result in either
Tenant or the Permitted Transferee having a net worth less than that of Tenant
on the date this Lease is executed (or in Landlord's reasonable business
discretion the Permitted Transferee does not have the financial ability to meet
the economic terms and conditions of the Lease); and further provided that such
assignment or sublease is not a subterfuge by Tenant to avoid its obligations
under this Lease. "Control" as used in this Section 15(g) shall mean the
possession, direct or indirect, of the power to direct or cause the direction of
the management and policies of a person or entity, or ownership of any sort,
whether through the ownership of voting securities, by contract or otherwise.

ARTICLE 16 - Damage Or Destruction
----------------------------------

     If the Project is damaged by fire or other insured casualty and the
insurance proceeds have been made available therefor by the holder or holders of
any mortgages or deeds of trust covering the Premises or the Project, the damage
shall be repaired by and at the expense of the Landlord to the extent such
insurance proceeds are available therefor and provided such repairs can, in
Landlord's sole opinion, be completed within one hundred eighty (180) days after
the occurrence of such damage becomes known to Landlord without the payment of
overtime or other premiums, and until such repairs are completed rent shall be
abated in proportion to the part of the Premises which is unusable by Tenant in
the conduct of its business, provided that if the damaged portion renders the
entire Premises unusable by Tenant, then rent shall be abated for the entire
Premises (but there shall e no abatement of rent by reason of any portion of the
Premises being unusable for a period equal to one (1) day or less).  If the
damage is due to the fault or neglect of Tenant, its employees, guests, invitees
and the like, there shall be no abatement of rent, and Tenant agrees to make a
claim, in an expeditious manner, under its insurance policies for the cost of
such damage or destruction, and to assign any such insurance proceeds from its
insurance policies to Landlord.  If pairs cannot, in Landlord's opinion, be
completed within one hundred eighty (180) days, Landlord may, at its option,
make them in a reasonable time and in such event this Lease shall continue in
effect and the rent shall be abated, if at all, in the manner provided in this
Article 16; provided, however, that if repairs cannot be completed within one
hundred eighty (180) days from commencement of construction, Tenant shall have
the right after the expiration of such one hundred eighty (180) days to
terminate this Lease upon thirty (30) days' written notice to Landlord.
Tenant's failure to so notify Landlord within such thirty (30) day period shall
be deemed to constitute Tenant's waiver of its right to terminate this Lease.
In addition, Landlord may elect not to rebuild and/or restore the Project, and
instead terminate this Lease, by notifying Tenant in writing of such termination
within thirty (30) days after Landlord receives notice of the date of damage,
such notice to include a termination date giving Tenant sixty (60) days to
vacate the Premises, but Landlord may so elect only if the Project shall be
damaged by fire or other casualty or cause, whether or not the Premises are
affected, and the damage is not fully covered, except for deductible amounts, by
Landlord's insurance policies.  A total destruction of the Project shall
automatically terminate this Lease.  Except as provided in this Article, there
shall be no abatement of rent and no liability of Landlord by reason of any
injury to or interference with Tenant's business or property arising

                                      21
<PAGE>

from such damage or destruction or the making of any repairs, alterations or
improvements in or to any portion of the Project or the Premises or in or to
fixtures, appurtenances and equipment therein. Tenant understands that Landlord
will not carry insurance of any kind to Tenant's furniture, furnishings,
fixtures or equipment, and that Landlord shall not be obligated to repair any
damage thereto or replace the same. with respect to any damage which Landlord is
obligated to repair or elects to repair, Tenant, as a material inducement to
Landlord entering into this Lease, irrevocably waives and releases its rights
under the provisions of Sections 1932 and 1933 of the California Civil Code.

ARTICLE 17 - Subordination
--------------------------

     This Lease is subject and subordinate to all ground or underlying Leases,
mortgages and deeds of trust which affect the property or the Project, including
all renewals, modifications, consolidations, replacements and extensions
thereof; provided, however, if the lessor under any such lease or the holder or
holders of any such mortgage or deed of trust shall advise Landlord that they
desire or require this Lease to be prior and superior thereto , upon written
request of Landlord to Tenant, Tenant agrees to promptly execute, acknowledge
and deliver any and all documents or instruments which Landlord or such lessor,
holder or holders deem necessary or desirable for purposes thereof.  Landlord
shall have the right to cause this Lease to be and become and remain subject and
subordinate to any and all ground or underlying leases, mortgages or deeds of
trust which may hereafter be executed covering the Premises, the Project or the
property or any renewals, modifications, consolidations, replacements or
extensions thereof, for the full amount of all advances made or to be made
thereunder and without regard to the time or character of such advances,
together with interest thereon and subject to all the terms and provisions
thereof, provided, however, that Landlord obtains from the lender or other party
in question a written undertaking in favor of Tenant to the affect that such
lender or other party will not disturb Tenant's right of possession under this
Lease if Tenant is not then or thereafter in breach following the expiration of
any grace or cure period of any covenant or provision of this Lease; and Tenant
agrees, within fifteen (15) days after Landlord's written request therefor, to
execute, acknowledge and deliver upon request any and all documents or
instruments requested by Landlord or necessary or proper to assure the
subordination of this Lease to any such mortgages, deed of trust, or leasehold
estates.  Tenant agrees not to assert against Landlord and hereby expressly
waives any claims for interference with, or disturbance of Tenant's right of
possession and/or breach of the covenant quiet enjoyment by reason of the
enforcement of any and all ground or underlying leases, mortgages and deeds of
trust affecting the Project or the Premises and all renewals, modifications,
consolidations, replacements and extensions thereof, whether or not the Lease is
subordinate thereto.  The foregoing notwithstanding, Landlord shall use its best
efforts to obtain a Non-Disturbance and Attornment Agreement from any
lienholders or mortgagees of the Project, whether currently existing or in the
future.  The Non-Disturbance and Attornment Agreement shall be in a form
reasonably acceptable to Tenant and any lienholders or mortgagees.

ARTICLE 18 - Eminent Domain
---------------------------

     If the whole of the Premises or the Project or so much thereof as to render
the balance unusable by Tenant shall be taken under power of eminent domain, or
is sold, transferred or conveyed in lieu thereof, this Lease shall automatically
terminate as of the date of such

                                      22
<PAGE>

condemnation, or as of the date possession is taken by the condemning authority
at Landlord's option. No award for any partial or entire taking shall be
apportioned, and Tenant hereby assigns to Landlord any award which may be made
in such taking or condemnation, together with any and all rights of Tenant now
or hereafter arising in or to the same or any part thereof; provided, however,
that nothing contained herein shall be deemed to give Landlord any interest in
or to require Tenant to assign to Landlord any award made to Tenant for the
taking of personal property and fixtures and one-half (1/2) of any leasehold
bonus as it relates to the Premises belonging to Tenant and removable by Tenant
at the expiration of the term hereof as provided hereunder or for the
interruption of, or damage to, Tenant's business. In the event of a partial
taking described in this Article 18, or a sale, transfer or conveyance in lieu
thereof, which does not result in a termination of this Lease, the rent shall be
apportioned according to the ratio that the part of the Premises remaining
useable by Tenant bears to the total area of the Premises. Tenant hereby waives
any and all rights it might otherwise have pursuant to Section 1265.130 of the
California Code of Civil Procedure.

ARTICLE 19 - Default
--------------------

     Each of the following acts or omissions of Tenant or of any guarantor of
Tenant's performance hereunder, or occurrences, shall constitute an "Event of
Default":

     (a) Failure or refusal to pay Monthly Basic Rental, Additional Rent or any
other amount to be paid by Tenant to Landlord hereunder within five (5) calendar
days after notice that the same was not paid when due or payable hereunder; said
five (5) day period shall be in lieu of, and not in addition to, the notice
requirements pertaining to the unlawful detainer statutes;

     (b) Except as set forth in item (g) below, failure to perform or observe
other covenant or condition of this Lease to be performed or observed within
thirty (30) days following written notice to Tenant of such failure; provided
that if the nature of such default cannot reasonably be cured within thirty (30)
days, Tenant shall not be in default if it commences such cure within such
period and diligently proceeds with such cure and does cure within ninety (90)
days.  Such thirty (30) day notice shall also constitute any notice required
under Section 1161 of the California Code of Civil Procedure;

     (c) Abandonment or vacationing or failure to accept tender of possession of
the Premises or any significant portion thereof, unless Tenant continues to pay
Monthly Basic Rental and all other sums due hereunder;

or arrangement for the appointment of a receiver of all or a portion of Tenant's
property; the filing against Tenant or any guarantor hereunder of any such
petition, or the commencement of a proceeding for the appointment of a trustee,
receiver or liquidator for Tenant, or for any guarantor hereunder, or of any of
the property of either, or a proceeding by any governmental authority for the
dissolution or liquidation of Tenant or any guarantor hereunder, if such
proceeding shall not be dismissed or

                                      23
<PAGE>

trusteeship discontinued within thirty (30) days after commencement of such
proceeding or the appointment of such trustee or receiver; or the making by
Tenant or any guarantor hereunder of an assignment for the benefit of creditors.

relief from such stay for Landlord in the event Tenant files a petition under
the United States Bankruptcy laws, for the purpose of Landlord pursuing its
rights and remedies against Tenant and/or a guarantor of this Lease;

     (f) Tenant's failure to cause to be released any mechanics liens filed
against the Premises or the Project within twenty (20) days after the date the
same shall have been filed or recorded; or

     (g) Tenant's failure to observe or perform according to the provisions of
Articles 17 or 25 within fifteen (15) business days after notice from Landlord.

All defaults following the expiration of any applicable notice or grace period
by Tenant of any covenant or condition of this Lease shall be deemed by the
parties hereto to be material.

ARTICLE 20 - Remedies
---------------------

     (a) In the event of a breach of or default under this Lease as provided in
Article 19 hereof, Landlord may exercise all of its remedies as may be permitted
by law, including but not limited to the remedy provided by Section 1951.4 of
the California Civil Code, and including without limitation, terminating this
Lease, reentering the Premises and removing all persons and property therefrom,
which property may be stored by Landlord at a warehouse or elsewhere at the
risk, expense and for the account of Tenant.  If Landlord elects to terminate
this Lease, Landlord shall be entitled to recover from Tenant the aggregate of
all amounts permitted by law, including but not limited to (i) the worth at the
time of any unpaid rent which has been earned at the time of such termination;
plus (ii) the worth at the time of award of the amount by which the unpaid rent
which would have been earned after termination until the time of award exceeds
the amount of such rental loss that Tenant proves could have been reasonably
avoided; plus (iii) the worth at the time of award of the amount by which the
unpaid rent for the balance of the Lease Term after the time of award exceeds
the amount of such rental loss that Tenant proves could have been reasonable
avoided; plus (iv) any other amount necessary to compensate Landlord for all the
detriment proximately caused by Tenant's failure to perform its obligations
under this Lease or which in the ordinary course of things would be likely to
result therefrom, specifically including but not limited to, brokerage
commissions and advertising expenses incurred, expenses of remodeling the
Premises or any portion thereof for a new tenant, whether for the same or a
different use, and any special concessions made to obtain a new tenant; and (v)
at Landlord's election, such other amounts in addition to or in lieu of the
foregoing as may be permitted from time to time by applicable law.  The term
"rent" as used in this Article 20(a) shall be deemed to be and to mean all sums
of every nature required to be paid by Tenant pursuant to the terms of this
Lease, whether to Landlord or to others.  As used in items (i) and (ii), above,
the "worth at the time of award" shall be computed by allowing interest at the
rate set forth in item (e), below, but in no case greater than the maximum
amount of such interest permitted by law.  As used in item (iii), above, the
"worth at the time of award" shall be computed by discounting such amount at the
discount rate of the Federal Reserve Bank of San Francisco at the time of award
plus one percent (1%).  If Landlord terminates this Lease or Tenant's right to
possession, Landlord shall

                                      24
<PAGE>

use reasonable efforts to mitigate Landlord's damages, and Tenant shall be
entitled to submit roof of such failure to mitigate as a defense to Landlord's
claims hereunder, if mitigation of damages by Landlord is required by applicable
law. Further, Tenant shall be liable for all unamortized leasing commissions
paid by or owing by Landlord arising from this Lease and extensions thereof.

     (b) Nothing in this Article 20 shall be deemed to affect Landlord's right
to indemnification for liability or liabilities arising prior to the termination
of this Lease for personal injuries or property damage under the indemnification
clause or clauses contained in this Lease.

     (c) Notwithstanding anything to the contrary set forth herein, Landlord's
re-entry to perform acts of maintenance or preservation of or in connection with
efforts to relet the Premises or any portion thereof, or the appointment of a
receiver upon Landlord's initiative to protect Landlord's interest under this
Lease shall not terminate Tenant's right to possession of the Premises or any
portion thereof and, until Landlord does elect to terminate this Lease, this
Lease shall continue in full force and effect and Landlord shall enforce all of
Landlord's rights and remedies hereunder including, without limitation, the
remedy described in California Civil Code Section 1951.4 (lessor may continue
lease in effect after lessee's breach and abandonment and recover rent as it
becomes due, if Lessee has the right to sublet or assign, subject only to
reasonable limitations).  Accordingly, if Landlord does not elect to terminate
this Lease on account of any default by Tenant, Landlord may, from time to time,
without terminating this Lease, enforce all of its rights and remedies under
this Lease, including the right to recover all rent as it becomes due.

     (d) All rights, powers and remedies of Landlord hereunder and under an
other agreement now or hereafter in force between Landlord and Tenant shall
cumulative and not alternative and shall be in addition to all rights, powers
and remedies given to Landlord by law, and the exercise of one or more rights or
remedies shall not impair Landlord's right to exercise any other right or
remedy.

     (e) Any amount due from Tenant to Landlord hereunder which is not paid
within five (5) days after Tenant's receipt of written notice that the same is
due shall bear interest at the lower of 16% per annum or the maximum lawful rate
of interest from the due date until paid, unless otherwise specifically provided
herein, but the payment of such interest shall not excuse or cure any default by
Tenant under this Lease.  In addition to such interest: (a) if Basic Rental is
not paid within ten (10) days after the same is due, a late charge equal to ten
percent (10%) of the amount overdue or $100, whichever is greater, shall be
assessed and shall accrue for each calendar month or part thereof until such
rental, including the late charge, is paid in full, which late charge Tenant
hereby agrees is a reasonable estimate of the damages Landlord shall Buffer as a
result of Tenant's late payment and (b) an additional charge of $25 shall be
assessed for any check (liven to Landlord by or on behalf of Tenant which is not
honored by the drawee thereof; which damages include Landlord's additional
administrative and other costs associated with such late payment and unsatisfied
checks and the parties agree that it would be impracticable or extremely
difficult to fix Landlord's actual damage in such event.  Such charges for
interest and late payments and unsatisfied checks are separate and cumulative
and are in addition to and shall

                                      25
<PAGE>

not diminish or represent a substitute for any or all of Landlord's rights or
remedies under any other provision of this Lease.

     (f) Tenant shall be liable for any other amount necessary to compensate
Landlord for all the detriment proximately caused by Tenant's default following
the expiration of any applicable cure or notice period under this Lease, or
which in the ordinary cause of things would be likely to result therefrom.

ARTICLE 21 - Transfer of Landlord's Interest
--------------------------------------------

     In the event of any transfer or termination of Landlord's interest in the
Premises or the Project by sell, assignments, transfer, foreclosure, deed-in-
lieu of foreclosure or otherwise whether voluntary or involuntary, Landlord
shall be automatically relieved of any and all obligations and liabilities on
the part of Landlord which accrue from and after the date of such transfer or
termination, including furthermore without limitation the obligation of Landlord
under Article 4 and California Civil Code 1950.7 above to return the security
deposit, provided said security deposit is transferred to said assignee.  Tenant
expressly waives and releases its rights with regard to its security deposit
pursuant to the provision of California Civil Code 1950.7 or any substitute or
successor statute to the extent the same could be asserted by Tenant against
Landlord.

ARTICLE 22 - Broker
-------------------

     In connection with this Lease, Landlord and Tenant each warrant and
represent that it has had dealings only with firm(s) set forth in Article 1.H.
of the Basic Lease Provisions and that it knows of no other person or entity who
is or might be entitled to a commission, finder's fee or other like payment in
connection herewith and each does hereby indemnify and agree to hold the other,
its agents, partners, representatives, officers, affiliates, shareholders,
employees, successors and assigns harmless from and against any and all loss,
liability and expenses that such party may incur should such warranty and
representation prove incorrect, inaccurate or false.

ARTICLE 23 - Parking
--------------------

     Tenant shall have the right but not the obligation to rent up to the number
of parking passes set forth in Article 1.1. of Basic Lease Provisions.  The
initial parking rates are set forth in Article 1.J. of the Basic Lease
Provisions.  Such parking shall be available upon terms and conditions to be
established from time to time by Landlord or Landlord's operator of such parking
facilities, but Landlord does not warrant or represent that the parking will
continue to be available if Tenant does not rent the same continuously from the
commencement of the term of this Lease.  Tenant agrees that it shall be liable
for and pay for any and all parking taxes imposed in connection with such
parking.

ARTICLE 24 - Waiver
-------------------

     No waiver by Landlord of any provision of this Lease shall be deemed to be
a waiver of any other provision hereof or of any subsequent breach by Tenant of
the same or any other provision.  No provision of this Lease may be waived by
Landlord, except by an instrument in

                                      26
<PAGE>

writing executed by Landlord. Landlord's consent to or approval of any act by
Tenant requiring Landlord's consent or approval shall not be deemed to render
unnecessary the obtaining of Landlord's consent to or approval of any subsequent
act of Tenant, whether or not similar to the act so consented to or approved. No
act or thing done by Landlord or Landlord's agents during the term of this Lease
shall be deemed an acceptance of a surrender of the Premises, and no agreement
to accept such surrender shall be valid unless in writing and signed by
Landlord. Any payment by Tenant or receipt by Landlord of an amount less than
the total amount then due hereunder shall be deemed to be in partial payment
only thereof and not a waiver of the balance due or an accord and satisfaction,
notwithstanding any statement or endorsement to the contrary on any check or any
other instrument delivered concurrently therewith or in reference thereto.
Accordingly, Landlord may accept any such amount and negotiate any such check
without prejudice to Landlord's right to recover all balances due and owing and
to pursue its other rights against Tenant under this Lease, regardless of
whether Landlord makes any notation on such instrument of payment or otherwise
notifies Tenant that such acceptance or negotiation is without prejudice to
Landlord's rights.

ARTICLE 25 - Estoppel Certificate
---------------------------------

     Tenant shall, at any time and from time to time, upon not less than fifteen
(15) days' prior written notice from Landlord, execute, acknowledge and deliver
to Landlord a statement in writing certifying the following information, (but
not limited to the following information in the event further information is
requested by Landlord): (i) that this Lease is unmodified and in full force and
effect (or, if modified, stating the nature of such modification and certifying
that this Lease, as modified, is in full force and effect); (ii) the dates to
which the rental and other charges are paid in advance, if any; (iii) the amount
of Tenant's security deposit, if any; and (iv) acknowledging that there are not,
to Tenant's knowledge, any uncured defaults on the part of Landlord hereunder,
and no events or conditions then in existence which, with the passage of time or
notice or both, would constitute a default on the part of Landlord hereunder, or
specifying such defaults, events or conditions, if any are claimed.  It is
expressly understood and agreed that any such statement may be relied upon by
any prospective purchaser or encumbrancer of all or any portion of the Real
Property.  Tenant's failure upon Landlord's reasonable request to deliver such
statement within such time shall, at the option of Landlord, constitute a
default under this Lease.  Furthermore, Tenant's failure to deliver such
statement within such time shall constitute an admission by Tenant that all
statements contained therein are true and correct.  Tenant agrees to execute all
documents required in accordance with this Article 25 within fifteen (15) days
after delivery of said documents.

ARTICLE 26 - Liability Of Landlord
----------------------------------

     Tenant agrees to look solely to Landlord's interest in the Project and the
Premises if any for the satisfaction of any remedy of Tenant for the collection
of a judgment (or other judicial process) requiring the payment of money by
Landlord in the event of any default by Landlord hereunder or any claim cause of
action, obligation, contractual statutory or otherwise by Tenant against
Landlord concerning, arising out of or relating to any matter relating to this
Lease and all of the covenants and condition or any obligations, contractual,
statutory, or otherwise set forth herein, and no other property or assets of
Landlord, or any officer, director, shareholder, partner, trustee, agent,
servant or employee of Landlord (the "Representative") shall be subject to levy,

                                      27
<PAGE>

execution or other enforcement procedure for the satisfaction of Tenant's
remedies under or with respect to this Lease, Landlord's obligations to Tenant,
whether contractual, statutory or otherwise, the relationship of Landlord and
Tenant hereunder, or Tenant's use or occupancy of the Premises.  Tenant further
understands that any liability, duty or obligation of Landlord to Tenant, shall
no longer accrue as of the date that Landlord or any of the Representatives no
longer have any right, title or interest in or to the Project, and shall
automatically cease if another entity has agreed to assume such liabilities
through a written assignment and assumption agreement.

ARTICLE 27 - Inability To Perform
---------------------------------

     This Lease and the obligations of Tenant hereunder shall not be affected or
impaired because Landlord is unable to fulfill any of its obligations hereunder
or is delayed in doing so, if such inability or delay is caused by reason of any
stoppage due to strikes, lockouts, acts of God, or any other cause previously,
or at such time, beyond the reasonable control or anticipation of Landlord
(collectively, a "Force Majeure") and Landlord's obligations under this Lease
shall be forgiven and suspended by any such Force Majeure, excepting, however,
Landlord's obligations under the last sentence of Article 2 and Article 11(g).

ARTICLE 28 - Hazardous Waste
----------------------------

     (a) Tenant shall not cause or permit any Hazardous Material (as defined in
Article 28(d) below) to be brought, kept or used in or about the Project by
Tenant, its agents, employees, contractors, or invitees, excluding, however,
customary office supplies, and equipment.  Tenant indemnitees Landlord from and
against any breach by Tenant of the obligations stated in the preceding sentence
and agrees to defend and hold Landlord harmless from and against any and all
claims, judgments, damages, penalties, fines, costs, liabilities, or losses
(including, without limitation, diminution in value of the Project, damages; for
the loss or restriction or use of rentable or useable space or of any amenity of
the Project, damages arising from any adverse impact or marketing of space in
the Project, and sum paid in settlement of claims, attorneys' fees, consultant
fees, and expert fees) which arise during or after the term of this Lease as a
result of such breach.  This indemnification of Landlord by Tenant includes,
without limitation, costs incurred in connection with any investigation of site
conditions or any cleanup, remedial, removal, or restoration work required by an
federal, state, or local governmental agency or political subdivision because of
Hazardous Material present in the soil or ground water on or under the Project.
Without limiting the foregoing, if the presence of any Hazardous Material on the
Project caused or permitted by Tenant results in any contamination of the
Project and subject to the provisions of Articles 9, 10 and 11, hereof, Tenant
shall promptly take all actions at its sole expense as are necessary to return
the Project to the condition existing prior to the introduction of any such
Hazardous Material and the contractors to be used by Tenant must be approved by
the Landlord, which approval shall not be unreasonably withheld so long as such
actions would not potentially have any material adverse long-term or short-term
effect on the Project and so long as such actions do not materially interfere
with the use and enjoyment of the Project by the other tenants thereof.

     (b) Landlord and Tenant acknowledge that Landlord may become legally liable
for the costs of complying with Laws (as defined in Article 29(e) below)
relating to Hazardous

                                      28

Tenant, including the following: (i) Hazardous Material present in the soil or
ground water on the project of which Landlord has no knowledge as of the
effective date of this Leases (ii) a change in Laws which relate to Hazardous
material which make that Hazardous Material which is present on the Property as
of the effective date of his Lease, whether known or unknown to Landlord, a
violation of such new Laws: (iii) Hazardous Material that migrates, flows,
percolates, diffuses, or in any way moves on to, or under the Project after the
effective date of this Lease; or Hazardous material present on or under the
Project as a result of any discharge, dumping or spilling (whether accidental or
otherwise) on the Product by other lessees of the Project or their agents,
employees, contractors, or invitees, or by others. Accordingly, Landlord and
Tenant agree that the cost of complying with Laws relating to Hazardous Material
on the Project for which Landlord is legally liable and which are paid or
incurred by Landlord shall not be an Operating Cost.

     (c) it shall not be unreasonable for Landlord to withhold its consent to
any proposed Transfer if (i) the proposed transferee's anticipated use of the
Premises involves the generation, storage, use, treatment, or disposal of
Hazardous Material; ( ) the proposed Transferee has been required by any prior
landlord, lender, or governmental authority to take remedial action in
connection with Hazardous material contaminating a property if the contamination
resulted from such Transferee's actions or use of the property in question; or
(iii) the proposed Transferee is subject to an enforcement order issued by any
governmental authority in connection with the use, disposal, or storage of a
Hazardous Material.

ARTICLE 29 - Surrender of Premises; Removal of Property
-------------------------------------------------------

     (a) The voluntary or other surrender of this Lease by Tenant to Landlord,
or a mutual termination hereof, shall not work a merger, and shall at the option
of Landlord, operate as an assignment to it of any or all subleases or
subtenancies affecting the Premises.

     (b) Upon the expiration of the term of this Lease, or upon any earlier
termination of this Lease, Tenant shall quit and surrender possession of the
Premises to Landlord in as good order and condition as the same are now and
hereafter may be improved by Landlord or Tenant, reasonable wear and tear and
repairs which are Landlord's obligation excepted, and shall, without expense to
Landlord, remove or cause to be removed from the Premises all debris and
rubbish, all furniture, equipment, business and trade fixtures, free-standing
cabinet work, moveable partitioning and other articles of personal property

provided in this Lease, shall be considered abandoned and Landlord may remove
any or all of such items and dispose of the same in any manner or store the same
in a public warehouse or elsewhere for the account and at the expense and risk
of Tenant, and if Tenant shall fail to pay the cost of storing any such property
after it has been stored for a period of ninety (90) days or more, Landlord may

at such times and places as Landlord, in its sole discretion, may deem proper,
without notice or to demand upon Tenant, for the payment of all or any part of
such charges or the removal of any such property, and shall apply the proceeds

ARTICLE 37 - Limited Arbitration/Dispute Resolution Procedure
-------------------------------------------------------------

     The submittal of all matters to arbitration in accordance with the terms of
this Article 37 shall be the sole and exclusive method, means and procedure to
resolve any and all claims, disputes or disagreements of Fifty Thousand Dollars
($50,000.00) or less arising under this Lease, except for (a) determination of
First Offer Rent and Fair Market Rental Rate, which shall be determined in
accordance with the applicable Articles above, (b) all claims by either party
which (i) seek anything other than enforcement of rights under this Lease, or
(ii) are primarily founded upon matters of fraud, willful misconduct, bad faith
or any other allegations of tortious action, and seek the award of punitive or
exemplary damages, and (c) claims relating to Landlord's exercise of any
unlawful detainer rights pursuant to California law or rights or remedies used
by Landlord to gain possession of the Premises or terminate Tenant's right of
possession to the Premises.  Should there be a dispute under the Lease for
amounts less than Fifty Thousand Dollars ($50,000.00), and accepted pursuant to
(a), (b) or (c) above, then such procedure shall be that Landlord and Tenant
shall select an arbitrator, which arbitrator shall be selected and qualified
pursuant to the rules of the Judicial Arbitration and Mediation Service (such
arbitrator to be selected by a process by which each party either agrees upon a
third party arbitrator or selects an independent third party, each of which
independent third party shall meet and agree upon such arbitrator, and, failing
to agree within fifteen (15) days after the commencement of such process, such
arbitrator shall be selected by the rules of the Judicial Arbitration Mediation
Service without regard to input by Landlord and Tenant) and whose costs shall be
paid for by the losing party unless it is not clear that there is a "losing"
party, in which event the costs of arbitration shall be shared equally.  The
purpose of the use of an arbitrator to resolve such dispute is to avoid the
delays incident to the court calendar system of the jurisdiction within which
the Premises are located.  Therefore, the parties agree that if the issue in
dispute between Landlord and Tenant under this Article may be expected to be
resolved under the then current calendar of the court of appropriate
jurisdiction within a period not exceeding six (6) months from the date the
issue is in dispute arises, then the arbitration process described hereinabove
shall not be utilized, an the matter shall proceed through the judicial process
in the court of appropriate jurisdiction.
