  • 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.

         Tenant shall pay the " BASIC RENT" set forth in Paragraph 1 hereof for

the Basic Rent for the fraction of the month starting with the Commencement Date
shall be paid on said Commencement Date and prorated on the basis of the actual
number of days in said month. If the term hereof ends on a day other than the
last day of a month, then the Basic Rent for the month during which said
expiration occurs shall be prorated on the basis of a thirty (30) day month. In
addition to said Basic Rent, Tenant agrees to Pay " ADDITIONAL RENT" as and when
hereinafter provided in this Lease. Basic Rent and Additional Rent are
hereinafter sometimes referred to collectively as the " RENT." The rent shall be
payable to Landlord, without deduction or offset, in lawful money of the United
States of America at the office maintained by Landlord in the Building, or to

         (a)   INCREASE IN DIRECT COSTS.


                                       2                              ________
                                                                        Tenant
                                                                      ________
                                                                      Landlord

<PAGE>


         Landlord hereby agrees to pay the amount (the "BASE COSTS") which is
the subordinate (lesser) amount between (i) $10.20 times the rentable square
feet of the Building and (ii) the Direct Costs (as defined herein) for the 2000
calendar year. Tenant shall pay, as Additional Rent, Tenant's Proportionate
Share of any increase in Direct Costs which exceeds the Base Costs. Landlord
shall be entitled to exercise the same rights and remedies upon default in the
Tenant's payment of Additional Rent as he has upon default in the Tenant's
payment of Basic Rent.

         (b) DEFINITIONS. 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 or levied upon the Building 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 are assessed or levied by the United States, the State
of California or any local government authority 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, but shall not include any net income taxes; provided, however, if 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 any Tax Costs, there shall be levied
(a) a tax, assessment, 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, 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 or levies or the part thereof so measured or
based, shall be deemed to be included in the term "Tax Costs."

             (ii) "OPERATING COSTS," which shall include but not be limited
to all costs and expenses incurred by Landlord in connection with the
maintenance, operation, replacement, ownership and repair of the Real
Property, the equipment, adjacent walks, landscaped and common areas, and the
parking structure, including, but not limited to, salaries, wages, medical,
surgical and general welfare benefits and pension payments, payroll taxes,
fringe benefits, employment taxes, workers' compensation, uniforms and
dry-cleaning thereof for all persons who perform duties connected with the
operation, maintenance and repair of the Building, its equipment and the
adjacent walks, and landscaped areas, including janitorial, gardening,
security, parking, operating engineering, elevators, painting, plumbing,
electrical, carpentry, heating, ventilation, air conditioning, window
washing, hired services, (but excluding persons performing services not
available to or performed for the benefit of substantially all building
Tenants), a reasonable allowance for depreciation of the cost of acquiring,
or the rental expense of, personal property used in the maintenance,
operation and repair of the Building, accountants' fees incurred in the
preparation of rent adjustment statements, legal fees, real estate tax
consulting fees, personal property taxes on property used in the maintenance
and operation of the Building, the current year's portion of capital
improvement costs amortized over the estimated useful life of the
improvement, provided only the following capital improvements are included:
(i) capital improvements required by government regulations, laws, or
ordinances (other than violations of laws existing as of the date of the
Lease), (ii) capital improvements incurred to reduce operating costs, or
(iii) capital improvements made to benefit the Building (and not due to a
violation of law existing as of the date of the Lease) provided the amortized
amount of capital expenditures to benefit the Building (and not otherwise
includable under (i) or (ii) above) shall not exceed $25,000 in any calendar
year; the cost of all charges for electricity, gas, water, and other
utilities furnished to the Building, including any taxes thereon; the cost of
all charges for fire and extended coverage, liability and all other insurance
for the Building carried by Landlord; any insurance deductibles paid by
Landlord respecting loss or damage to the Building, its equipment

                                       3                              ________
                                                                        Tenant
                                                                      ________
                                                                      Landlord


<PAGE>


or areas and items appurtenant thereto; the cost of all building and cleaning
supplies and materials; the cost of all charges for cleaning, maintenance and
service contracts and other services with independent contractors (including
property management fees); and license, permit and inspection fees relating
to the Building. In the event, during any calendar year, the Building is less
than ninety-five percent (95%) occupied at all times, the Operating Costs
shall be adjusted to reflect the Operating Costs of the Building as though it
were ninety-five percent (95%) occupied at all times and the increase or
decrease in rent shall be based upon such Operating Costs as so adjusted. If
Landlord is not furnishing any particular work or service (the cost of which,
if performed by Landlord, would be included in Operating Costs) to a tenant
who has undertaken to perform such work or service in lieu of the performance
thereof by Landlord, Operating Costs shall be deemed to be increased by
amount equal to the additional Operating Costs which would reasonably have
been incurred during such period by Landlord if it had at its own expense
furnished such work or service to such tenant.

         (c) PAYMENT OF DIRECT COSTS.

             (i) Upon the commencement of this Lease, Landlord may elect to
deliver to Tenant an estimate of the Direct Costs for the calendar year in
which the term of this Lease commences. By the end of each calendar year
thereafter, Landlord may elect to deliver to Tenant an estimate of the Direct
Costs for the following calendar year. In the event such estimates are
delivered, Tenant shall pay to Landlord on the first day of each month during
the term of this Lease an amount equal to Tenant's Proportionate Share, as
set forth in Paragraph l (c), of the average monthly increase in Direct Costs
over Base Costs for such year as estimated by Landlord. Following the end of
each calendar year, Landlord shall deliver to Tenant a statement ("LANDLORD'S
STATEMENT") of the actual Direct Costs for such calendar year and the amount
due for Tenant's Proportionate Share of the increase over the Base Costs. If
the actual amount of Tenant's Proportionate Share of the Direct Costs over
Base Costs for such year exceeds the amount paid by Tenant to Landlord as an
estimate therefor, Tenant shall pay the difference to Landlord within fifteen
(15) days of delivery to Tenant of the statement of the Direct Costs for such
year. If the estimated amounts paid by Tenant to Landlord for the increase in
Direct Costs for such year exceeds the actual amount due over Base Costs for
such year, such excess shall be credited against the amounts due from Tenant
thereafter pursuant to this Paragraph 4(c)(i) or, if this Lease has
terminated, such excess shall be credited against any amounts which Tenant
owes Landlord pursuant to this Lease and, to the extent all amounts which
Tenant owes Landlord pursuant to this Lease have been paid, Landlord shall
promptly pay such excess to Tenant. In the event Landlord does not elect to
deliver an estimate of Direct Costs to Tenant as provided above, then upon
Landlord delivering to Tenant a statement of the actual Direct Costs for such
calendar year and the amount due for Tenant's Proportionate Share over Base
Costs, Tenant shall pay such sum which is shown due on said statement with
the next payment of Basic Rent due or, in the event Tenant elects such,
Tenant may pay the sum due on such statement over the next following twelve
(12) months together with interest thereon at ten percent (10%) per annum,
principal and interest amortized equally over such twelve (12) months. Any
delay by Landlord in delivering any estimate or statement pursuant to this
Paragraph shall not act as a waiver or relieve Tenant of its obligations as
set forth herein.

         (d) EXERCISE OF RIGHT BY TENANT:

             (i) Provided that Tenant is not in default under this Lease and
provided further that Tenant strictly complies with the provisions of this
paragraph, Tenant shall have the right to reasonably review supporting data
for any portion of the Landlord's Statement that Tenant claims is incorrect
provided that Tenant gives Landlord reasonable times for such review.

             (ii) In order for Tenant to exercise its right under this
paragraph, Tenant shall, within sixty (60) days after any such Landlord's
Statement is sent, deliver a written notice


                                       4                              ________
                                                                        Tenant
                                                                      ________
                                                                      Landlord


<PAGE>


to Landlord specifying the portions of the Landlord's Statement that are
claimed to be incorrect, and Tenant shall simultaneously pay to Landlord all
amounts due from Tenant to Landlord as specified in the Landlord's Statement.
If Tenant does not deliver such notice in the time period set forth above,
Landlord's Statement shall be deemed fully accepted by Tenant and shall not
be subject to any challenge by Tenant.

             (iii) Except as expressly set forth in subparagraph (3)(b)
below, in no event shall Tenant be entitled to withhold, deduct, or offset
any monetary obligation of Tenant to Landlord under the Lease (including,
without limitation, Tenant's obligation to make all rental payments and all
payments for its share of estimated and actual Additional Rent) pending the
completion of and regardless of the results of any review of records under
this paragraph.

             (iv) The right of Tenant under this paragraph may only be
exercised once for any Landlord's Statement, and if Tenant fails to meet any
of the above conditions as a prerequisite to the exercise of such right, the
right of Tenant under this paragraph for a particular Landlord's Statement
shall be deemed waived.

         (e) PROCEDURES FOR REVIEW

             (i) Tenant acknowledges that Landlord maintains its records for
this property at its offices in 8730 Sunset Towers, Office of the Building,
8730 Sunset Boulevard, Los Angeles, California, and Tenant therefore agrees
that any review of records under this paragraph shall occur at such location.

             (ii) Any review to be conducted under this paragraph shall beat
the sole expense of Tenant and shall be conducted by an independent firm of
certified public accountants of national standing.

             (iii) Tenant acknowledges and agrees that any records reviewed
under this paragraph constitute confidential information of Landlord, which
shall not be disclosed to anyone other than the accountants performing the
review and the principals of Tenant who receive the results of the review.

             (iv) The disclosure of such information to any other person,
whether or not caused by the conduct of Tenant, shall constitute a material
breach of this Lease.

         (f) FINDING OF ERROR

             (i) Any error disclosed by the review of record under this
paragraph shall be promptly corrected, provided that Landlord shall have the
right to cause another review of the records to be made by an independent
firm or certified public accountants of national standing. In the event of a
disagreement between the two accounting firms, the review that discloses the
lease amount of deviation from the Landlord's Statement shall be deemed to be
correct.

             (ii) In the event that the results of the review of records
[taking into account, if applicable, the results of any additional review
caused by Landlord pursuant to subparagraph (c)(1) above] reveal that Tenant
has overpaid obligations for a preceding period, the amount of such overpayment
shall be credited against Tenant's subsequent installment obligations to pay
its share of estimated or actual Additional Rent.

             (iii) In the event that such results show that Tenant has
underpaid its obligations for a preceding period, the amount of such
underpayment shall be paid by Tenant to Landlord with the next succeeding
installment obligation of estimated or actual Additional Rent.

         (g) EFFECT OF TENANT'S DEFAULT. In the event that Tenant becomes in
default of its obligations under this Lease at any time during the pendency
of a review of records under this


                                       5                              ________
                                                                        Tenant
                                                                      ________
                                                                      Landlord


<PAGE>


paragraph, said right to review shall immediately cease and the matters
originally set forth in the Landlord's Statement shall be deemed to be
correct.

         (h) CONSUMER PRICE INDEX ADJUSTMENT. The monthly basic rent shall be
adjusted annually as of January 1 (" ANNUAL ADJUSTMENT DATE"), upward, but
not downward, as follows: The adjustment shall be calculated by referring (a)
to the index figure for the month of November of the year immediately
preceding the year in which this Lease is executed (" BASE MONTH") and (b)
the index figure for the month of November preceding the annual adjustment
date (" ADJUSTMENT MONTH") as shown in the Consumer Price Index, All Urban
Consumers, for the Los Angeles-Long Beach-Anaheim area, as published by the
Bureau of Labor Statistics of the United States Department of Labor (" CPI")
base on the period 1982-84=100. If the index figure for the adjustment month
is higher than the index figure for the base month said monthly Basic Rent
shall be increased effective as of January 1 following the adjustment month
by the same percentage as the percentage increase of the CPI. If the 1982
base of the CPI is changed, the 1982 base shall be converted to the new base
in accordance with the tables issued by said Bureau, and the base as so
converted shall be used. If the CPI is discontinued or the 1982 base cannot
be so converted, Landlord in its reasonable discretion shall select an
alternative index to adjust the monthly Basic Rent to reflect the increase in
the consumer price of goods and services. [SEE ADDENDUM SECTION 6]

     5.  SECURITY DEPOSIT. Concurrently with the execution of this Lease,
Tenant shall deposit with Landlord the amount specified in Paragraph 1 herein
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 the payment of rent, Landlord may 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 its original amount. If monthly Basic Rent
is increased, whether pursuant to Paragraph 4 or otherwise, the amount of the
security deposit required to be maintained by Tenant shall also be increased
to an amount that bears the same proportion to the increased Basic Rent as
the initial security deposit amount bore to the initial Basic Rent. Landlord
shall not be required to keep this security deposit separate from its general
funds and Tenant shall not be entitled to interest on such deposit. At the
expiration of the term of this Lease or earlier termination hereof the
security deposit or any unapplied balance thereof shall be used and applied
to cure any defaults of Tenant under the Lease or compensate Landlord for
loss or damage due to Tenant failure to satisfy its obligations under this
Lease. Tenant hereby waives the provisions of Section 1950.7 of the
California Civil Code, and all other provisions of law, now or hereafter in
force, which provide that Landlord may claim from a security deposit only
those sums reasonably necessary to remedy defaults in the payment of rent, to
repair damage caused by Tenant or to clean the Premises. The remainder of the
security deposit, if any, shall be returned to Tenant, or at Landlord's
option, to Tenant's assignee of this Lease.

     6.  HOLDING OVER. Should Tenant, with Landlord's prior written consent,
hold over after the termination of this Lease, Tenant shall become Tenant
from month to month, upon the terms herein provided as may be applicable to a
month to month tenancy and any such holding over shall not constitute an
extension of this Lease. During such holding over, Tenant shall pay monthly,
in advance, Basic Rent at one hundred fifty percent (150%) or a lesser amount
in the sole discretion of the Landlord of the rate of Basic Rent 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 the increase in Direct Costs
over Base Costs. Any other holding over shall create a tenancy at sufferance,
and the reasonable rental rate for which Tenant shall be liable in an
unlawful detainer action shall be deemed to be two hundred percent (200%) of
the Basic Rent paid under the Lease. Tenant


                                       6                              ________
                                                                        Tenant
                                                                      ________
                                                                      Landlord


<PAGE>


agrees to indemnify, defend and hold Landlord harmless from and against any
and all claim, loss, damage, cost or expense arising out of Tenant's delay in
surrendering the Premises, including, without limitation, any claims made by
any succeeding tenant of the Premises.

     7.  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. If any or all
of Tenant's fixtures, furnishings, equipment and other personal property
shall be assessed and taxed with the 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.

     8.  USE. Tenant shall use and occupy the Premises only for the use
specified in Paragraph 1, 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, and Tenant agrees that it will use the Premises
in such a manner so as not to interfere with or infringe the rights of other
Tenants in the Building. 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 the condition, use or occupancy of the Premises or the Building,
including structural changes to the extent required due to Tenant's use of
the Premises in excess of normal office use or Tenant's improvements to the
Premises in excess of normal office improvements. Tenant acknowledges that it
has made its own investigation and determination of the suitability of the
Premises for its business operations and the requirements that may be imposed
by Applicable Laws in order to conduct its business at the Premises and in no
event shall Landlord have any responsibility for taking any action to obtain
any conditional use permit, provide parking (except as expressly provided
herein) or take other action to make Tenant's occupancy of the Premises
comply with Applicable Laws. Tenant shall not do or permit to be done
anything which will invalidate or increase the cost of any fire and extended
coverage insurance policy covering the Building 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
including without limitation thereto, the installation of fire extinguishers
or an automatic dry chemical extinguishing system. Tenant shall promptly upon
demand reimburse Landlord for any additional premium charges for such policy
by reason of Tenant's failure to comply with the provisions of this
Paragraph. [SEE ADDENDUM SECTION 7.]

     9.  CONDITION OF PREMISES. Except for the work to be performed to the
Premises pursuant to the terms of the Work Letter attached hereto as Exhibit
"B", Tenant hereby agrees that Premises shall be taken "AS IS," "WITH ALL
FAULTS," "WITHOUT ANY REPRESENTATIONS OR WARRANTIES," and Tenant hereby
agrees and warrants that it has inspected the condition of the Premises and
the suitability of same for Tenant's purposes, and Tenant does hereby waive
and disclaim any objection to, cause of action based upon, or claim that its
obligations hereunder should be reduced or limited because of the condition
of the Premises or the Building or the suitability of same for Tenant's
purposes. Tenant acknowledges that neither Landlord nor any agent nor any
employee of Landlord has made any representations or warranty with respect to
the Premises, the size thereof, or the Building 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 Building were at such time in satisfactory condition. Tenant
hereby waives Section 1941 and 1942 of the Civil Code of California or any
successor provision of law.

     10. REPAIRS AND ALTERATIONS. Tenant shall keep the Premises in good
condition and repair. All damage or injury to the Premises or the Building
caused by the act or negligence of Tenant, its employees, agents or visitors,
guests, invitees or licensees shall be properly repaired by Tenant, at its
sole cost and expense, to the satisfaction of Landlord. Landlord may


                                       7                              ________
                                                                        Tenant
                                                                      ________
                                                                      Landlord


<PAGE>


make any repairs which are not promptly made by Tenant and charge Tenant for
the cost thereof which costs shall be paid by Tenant within five (5) days
from invoice by Landlord. Tenant shall be responsible for the design and
function of all non-standard improvements to the Premises, whether or not
installed by Landlord at Tenant's request. Tenant waives all right to make
repairs at the expense of Landlord, or to deduct the cost thereof from the
rent. Tenant shall make no alterations, changes, repairs, or additions in or
to the Premises without Landlord's prior written consent, and then only by
contractors or mechanics approved by Landlord and upon the approval by
Landlord 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 commencement date
therefor, Tenant shall not commence any work prior to such date. Tenant
hereby indemnities 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 any permitted alterations, changes, repairs or
additions are made, they shall be made at Tenant's expense and shall become
the property of the Landlord, except that Landlord may, by written notice to
Tenant given at least thirty (30) days prior to the end of the term, require
Tenant at Tenant's expense to remove all partitions, counters, railings and
the like installed by Tenants, and to repair any damages to the Premises
caused by such removal. [SEE ADDENDUM SECTION 8.]

     11. LIENS. Tenant shall keep the Premises and the Real Property 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, changes,
repairs, or improvement 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) and shall secure, at Tenant's own cost and expense, a
completion and payment bond in an amount equal to one hundred fifty percent
(150%) of the cost of the work to be performed, in a form and with a bonding
company satisfactory to Landlord, for said work which shall name Landlord and
Tenants as payees thereon. If there shall be recorded against the Premises or
the Real Property 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) business 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 and
the amount thereof, upon being billed to Tenant shall be immediately paid by
Tenant to Landlord, or to require that Tenant deposit with Landlord in lawful
money of the United States, one hundred and one hundred fifty percent (150%)
of the amount of such claim, which sum may be retained by Landlord until such
claims 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 attorney's fees incurred by
Landlord, and shall remit the balance thereof to Tenant.

     12. BUILDING SERVICES.

         (a) Landlord agrees to furnish to the Premises, at its expense, so
long as Tenant is not in default hereunder, from 9:00 a.m. to 5:30 p.m.
Mondays through Fridays and 9:00 a.m. to 1:00 p.m. on Saturdays, local and
national holidays excepted, air conditioning and heat, elevator service,
electric current for normal lighting and fractional horsepower office
machines and, on the same floor as the Premises, water for lavatory and
drinking purposes, all in such reasonable quantities as in the judgment of
Landlord is reasonably necessary for the comfortable occupancy


                                       8                              ________
                                                                        Tenant
                                                                      ________
                                                                      Landlord


<PAGE>


of the Premises. Janitorial and maintenance services will be furnished five
days per week. Tenant shall comply with all rules and regulations which
Landlord may reasonably establish for the proper functioning and protection
of the air conditioning, heating, elevator, electrical and plumbing systems.
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, force majeure events, necessary repairs or
other cause. Except as specifically provided in this Paragraph 12, Tenant
agreed to pay upon being billed therefor by Landlord 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
Building. Landlord's obligation to render to the Premises the services set
forth in this Paragraph 12 is conditional upon the payment by Tenant of all
sums due under this Lease, including but not limited to sums which are in
dispute.

         (b) Tenant shall not permit the consumption in the Premises of more
than two (2) watts per net usable square foot in the Premises in respect of
office lighting nor shall Tenant permit the consumption in the Premises of
more than two (2) watts per net usable square foot of space in the Premises
in respect of the power outlets therein, at any one time. If such limits are
exceeded, Landlord shall have the right to remove any lighting fixture or any
fluorescent tube or bulb therein as it deems necessary and/or to charge
Tenant for the cost of the additional electricity consumed. Tenant will not
without the written consent of Landlord use any apparatus or devise in the
Premises, including without limitation electronic data procession machines,
punch card machines and machines 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.

         (c) If Tenant shall require electric current in excess of that which
Landlord is obligated to furnish under Paragraph 12(b) above, Tenant shall
first obtain the consent of Landlord, which Landlord may refuse, 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 and Tenant agrees to pay to
Landlord promptly upon demand therefor by Landlord for all such electric
current consumed by any such use as shown by said meter, at the rates charged
for such services by the public utility providing the service, 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 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 property, however occurring, through
or in connection with or incidental to failure to furnish any of the
foregoing.

         (e) If Tenant requires heating, ventilation and/or air conditioning
during times other than the times provided in Paragraph 12(a) above, Tenant
shall give Landlord such advance notice as Landlord shall reasonably require
and shall pay for the use of such equipment such reasonable fee or charge as
Landlord shall require.

<PAGE>


         (f) Landlord may impose a reasonable charge for any utilities or
services, including without limitation electric current, required to be
provided by Landlord for use of the Premises other than during the times
provided in Paragraph 12(a) above.

     13. 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 notices as provided by law, or which Landlord deems necessary
for the protection of Landlord or the Real Property, showing the same to
prospective Tenants or purchasers of the Real Property, and for making such
alterations, repairs, improvements or additions to the Premises or to the
Building as Landlord may deem necessary or desirable. Landlord may enter at
any time in case of emergency. If Tenant shall not be present to open the
Premises when such an entry by Landlord is necessary or permitted hereunder,
Landlord may enter by means of a master key or may enter forcibly, without
liability to Tenant except for any failure to exercise due care for Tenant's
property, and without affecting this Lease.

         14. INDEMNITY; EXEMPTION OF LANDLORD FROM LIABILITY.

             (a) Except to the extent attributable to Landlord's negligence,
breach of lease or willful misconduct, Tenant shall indemnify, defend and
hold Landlord and Landlord's agents and employees harmless from any and all
claims, demands, liabilities, causes of action, costs and attorneys' fees
arising from Tenant's use of the Premises and/or Real Property from the
conduct of its business, from any activity, work or thing which may be
permitted or suffered by Tenant in or about the Premises and/or Real
Property, from any and all claims arising from any breach or default in the
performance of any obligation on 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, customers or members and from
any and all costs, attorney's 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 loss
or damage to personal property and Tenant hereby waives all claims in respect
thereof against Landlord, excepting only where the damage is caused solely by
willful conduct of Landlord or its authorized agents.

             (b) Landlord shall not be liable for injury to Tenant's
business, or loss of goodwill or income therefrom, or for damage that may be
sustained by the person, or property of Tenant, its employees, invitees,
customers, agents, or contractors, or any other person in, on or about the
Premises and/or Real Property 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 and/or Real Property, 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, whether such damage or injury results from conditions
arising upon the Premises/Building or upon other portions of the Building or
Real Property from other sources or places and regardless of whether the
cause of such damage or injury or the means of repairing the same is
inaccessible to Tenant, except in connection with damage or injury resulting
from the sole 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.

             (c) Tenant acknowledges that Landlord's election to provide
mechanical surveillance or to post security personnel in the Building is
solely with Landlord's discretion; Landlord shall have no liability in
connection with the decision whether or not to provide such services and
Tenant hereby waives all claims based thereon. Landlord shall not be liable
for losses due to theft, vandalism, or like causes. Tenant acknowledges that
in the event Landlord shall elect to provide mechanical surveillance or to
post security personnel in the Building, that Landlord's election to do so
shall not make Landlord liable for the failure of such measures to

protect Tenant or its employees, agents, invitees or contractors from injury,
loss, damage, cost or expense.

             (d) Except as provided below, Landlord shall not be personally
liable for the performance of Landlord's obligations under this Lease. If
Tenant acquires any rights or remedies against Landlord (including, but not
limited to, the right to satisfy a judgment), these rights and remedies shall
be satisfied solely from the lesser of (a) Landlord's estate and interest in
the Real Property (or the proceeds therefrom including insurance proceeds and
the proceeds from sale), or (b) the estate and interest Landlord would have
in the Real Property (or the proceeds therefrom) if the Real Property were
encumbered by third-party debt in an amount equal to eighty percent (80%) of
the value of the Real Property; such rights and remedies shall not be
satisfied, in any event, from any other property or assets of Landlord.

     15. INSURANCE.

         15.1 TENANT'S INSURANCE. Tenant shall have the following
insurance obligations.

         (a) LIABILITY INSURANCE. Tenant shall obtain and keep in full force
a policy of commercial general liability and property damage insurance,
including but not limited to personal injury, broad form contractual
liability, owner's (i.e., Tenant's) contractors protective and broad form
property damage under which Tenant is named as the insured and Landlord,
Landlord's agent and any lessors and mortgagees (whose names shall have been
furnished to Tenant) are named as additional insureds. The minimum limits of
liability shall be a combined single limit with respect to each occurrence of
not less than Two Million Dollars ($2,000,000.00). The policy shall contain a
cross liability endorsement, and shall be primary coverage for Tenant and
Landlord for any liability arising out of Tenant's and Tenant's Employees'
use, occupancy or maintenance of the Premises and Project and all areas
appurtenant thereto. Tenant shall also obtain and keep in force automobile
liability, including bodily injury and property damage, with minimum limits
of liability of a combined single limit with respect to each occurrence of
not less than Two Million Dollars ($2,000,000.00). Such insurance policies
shall provide that they are primary insurance and not "excess over" or
contributory. Not more frequently than once each year, if, in the opinion of
Landlord's lender or of the insurance consultant retained by Landlord, the
amount of public liability and property damage insurance coverage at that
time is not adequate, Tenant shall increase the insurance coverage as
required by either Landlord's lender or Landlord's insurance consultant;
provided however, that in no event shall any such insurance coverage be
increased in excess of that which is from time to time being required by
comparable landlord of comparable tenants leasing comparable amounts of space
in other first-class buildings in the vicinity of the Building.

         (b) TENANT'S PROPERTY INSURANCE. Tenant at its cost shall maintain
on all of its personal property, including, without limitation, Tenant's
valuable papers, furniture, fixtures, leasehold improvements installed by or
at the expense of Tenant, equipment and inventory, in, on, or about the
Premises, an "all risk" property policy including coverage for sprinkler
leakage and containing an agreed amount endorsement in an amount not less
than one hundred percent (100%) of the full replacement cost valuation under
which Tenant is named as the insured and Landlord, Landlord's agents and any
lessors and mortgagees (whose names shall have been furnished to Tenant) are
additional insureds as their interests may appear. The proceeds from any such
policy shall be used by Tenant for the replacement of such personal property
and improvements. The "full replacement cost valuation" of the personal
property and improvements to be insured under this Paragraph 15 shall be
furnished to the company issuing the insurance policy by Tenant at least once
every year. Tenant's property insurance shall not provide for a deductible of
more than One Thousand Dollars ($1,000).

<PAGE>


         (c) WORKERS' COMPENSATION INSURANCE. Tenant shall maintain Workers'
Compensation insurance as required by law and Employer's Liability insurance
in an amount not less than One Million Dollars ($1,000,000.00).

         (d) BUSINESS INTERRUPTION/EXTRA EXPENSE INSURANCE. Tenant shall
maintain loss of income, business interruption and extra expense insurance in
such amounts as will reimburse Tenant for direct or indirect loss of earnings
and incurred costs attributable to the perils commonly covered by Tenant's
property insurance described above but in no event less than one year's loss
of income, business interruption, and extra expense. Such insurance will be
carried with the same insurer that issues the insurance for the personal
property.

         (e) OTHER COVERAGE. Tenant, at its cost, shall maintain such other
insurance as Landlord may reasonably require from time to time.

         (f) INSURANCE CRITERIA.  All the insured required to be maintained
by TENANT under this Lease shall:

             (i)   Be issued by insurance companies admitted in the State of
California, with a financial rating of at least an AX as provided by the most

             (ii)  Be issued as a primary policy;

             (iii) Contain an endorsement requiring thirty (30) days' written

the insurance coverages required hereunder and naming Landlord and any other
interested parties as additional insured shall be deposited with Landlord not
less than thirty (30) days before expiration of the term of the policy.

             In the event Tenant does not comply with the requirements of
Paragraph 15.1(a) above, Landlord may, at its option and at Tenant's sole
cost and expense, purchase such insurance coverage to protect Landlord. The
cost of the premium of any such insurance purchased by Landlord shall be paid
to Landlord by Tenant, as additional rent, immediately upon demand therefor.

             15.2 LANDLORD'S INSURANCE. Landlord shall have the following
obligations:

                  Landlord shall maintain in effect at all times "all risk"
property insurance covering fire, lightning, windstorm, vandalism, malicious
mischief and all other risks normally covered by "all risk" policies in the
downtown Los Angeles financial district. Such insurance shall provide
coverage for one hundred percent (100%) of the full replacement cost
valuation of the Building, tenant improvements paid for by Landlord and
Landlord's personal property including its furniture, fixtures and equipment,
subject to commercially reasonable deductibles. Landlord shall also obtain
and keep in full force (a) a policy of commercial general liability insurance
and (b) loss of rent insurance, all such insurance being in amounts and with
deductibles comparable to the insurance being carried by landlords of other
comparable firs class institutional quality office buildings in the Sunset
Strip district. Landlord may, but shall not be required to, maintain
earthquake coverage.

     15.3  ALLOCATION OF INSURED RISKS/WAIVER OF SUBROGATION. Landlord
and Tenant mutually waive and release any and all rights of RECOVERY and claims
either has against the other and each of their respective agents, employees,
directors, shareholders, officers, partners, trustees and representatives, for
losses or damages that are caused by or result from perils insured against under
any insurance policies carried by the parties, but only to the extent of such
insurance coverage afforded, provided, however, that nothing contained in this
subparagraph (b) shall derogate the provisions of Paragraph 14, above. Landlord
and Tenant shall cause each insurance policy obtained by them, or either of
them, to provide that the insurance company waives all right of recovery by way
of subrogation against either Landlord or Tenant in connection with any lose or
damage covered by any such policy or policies.

     16.   ASSIGNMENT AND SUBLETTING.

           (a) The Tenant shall not, either voluntarily or by operation of
law, directly or indirectly, sell, hypothecate, assign or transfer
(collectively " ASSIGNMENT") this Lease, or sublet the Premises or any part
thereof, or permit the Premises or any part thereof to be occupied by anyone
other than Tenant or Tenant's employees, without the prior written consent of
Landlord in each instance. A transfer of stock control in Tenant, if Tenant
is a corporation, or the transfer of any partnership interest in Tenant, if
Tenant is a partnership, shall be deemed an act of assignment hereunder.
Landlord's consent to an Assignment or subletting shall not be unreasonably
withheld, provided the proposed procedures contained in subparagraphs (b) and
(c) below are followed and provided that the assignee or subtenant (i) is
satisfactory to Landlord as to credit, character and professional standing,
(ii) will meet any other Tenant requirements then generally imposed by
Landlord with respect to new tenants of the Building, and (iii) will use the
Premises for the same use and in the same manner specified in Paragraph 1
hereof. It shall not be unreasonable for Landlord to withhold its consent to
any proposed Assignment or Sublet if (i) the occupancy of the proposed
assignee or subtenant will tend to impair the character or dignity of the
Building (ii) the proposed use will impose any additional burden upon
Landlord in the operation of the Building. (iii) the proposed transferee's
anticipated use of the Premises involves the generation, storage, use,
treatment, or disposal of Hazardous Material; (iv) 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 (v) 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.

           Any sale, assignment, mortgage, transfer or subletting of this
Lease which is not in compliance with the provisions of this Paragraph 16 shall
be void and shall, at the option of Landlord, terminate this Lease. The consent
by Landlord to one assignment or subletting shall not relieve Tenant for
obtaining the prior written consent of Landlord to any further assignment or
subletting or release Tenant from any liability or obligation hereunder, whether
or not then accrued. Further, all advertising with respect to the leasing,
subletting or assignment of space in the Building must be approved in writing by
Landlord prior to publication.

           (b)  As conditions precedent to Landlord's consent to any
assignment or subletting of the whole or any part of the Premises:

                (i) At least twenty five (25) days prior to any proposed
assignment or subletting, Tenant shall submit to Landlord a statement
containing: (A) the name and address of the proposed assignee or subtenant;
(B) a financial statement of the proposed assignee or subtenant containing
bank and other credit references; (C) the type of use proposed for the
Premises; and (D) all of the principal terms and conditions of the proposed
assignment or subletting including, but not limited to, the proposed
commencement and expiration dates of the

term thereof and the amount of rent payable by the assignee or subtenant and,
a floor plan delineating the proposed assigned or sublet area; and

                (ii) Tenant shall deliver to Landlord an original assignment
or sublease executed by Tenant and the proposed assignee or subtenant on a
form approved by Landlord;

                (iii) Tenant shall pay Landlord's reasonable attorneys fees,
not to exceed $1,500, and other costs incurred in connection with such
assignment or subletting; plus a non-refundable fee of $250 for Landlord's
time in processing Tenant's request;

                (iv) If the consideration received by Tenant for such
assignment or sublease (after deducting therefrom leasing commissions, rental
paid during any period in which the Premises were vacant, the unamortized
part of Tenant's contribution to over-standard Tenant improvements, if any,
and any other reasonable out-of-pocket expenses of Tenant incurred in
connection with such subleasing or assignment of the Premises) exceeds the
Basic Rent and the Additional Rent, or pro rated portion thereof, as the case
may be, for such space reserved in this Lease, Tenant shall pay to Landlord
when received, an additional Basic Rent, one hundred percent (100%) of the
excess of the consideration paid in connection with the assignment or
sublease, over the Basic Rent and Additional Rent then due reserved in this
Lease applicable to the assigned or subleased space. [SEE ADDENDUM SECTION 9]

     17.   DAMAGE OR DESTRUCTION.

           (a)  DAMAGE - INSURED. In the event the Premises or the Building
are damaged by any casualty which is covered under fire and extended coverage
insurance carried by Landlord, then Landlord shall restore such damage
provided insurance proceeds are available to Landlord to pay eighty percent
(80%) or more of the cost of restoration and provided such restoration can be
completed within sixty (60) days after the commencement of the work in the
opinion of a registered architect or engineer appointed by Landlord. In such
event this Lease shall continue in full force and effect, except that Tenant
shall be entitled to an equitable reduction of rent while such restoration
takes place, such reduction to be based upon the extent to which the
restoration efforts interfere with Tenant's business in the Premises.

           (b)  DAMAGE - UNINSURED. In the event the Premises or the Building
are damaged by a risk not covered by Landlord's policy or the proceeds of
insurance available to Landlord are less than eighty percent (80%) of the
cost of restoration, or if the restoration cannot be completed with sixty
(60) days after the commencement of work in the opinion of the registered
architect or engineer appointed by Landlord, then Landlord shall have the
option either to (i) repair or restore such damage, this Lease continuing in
full force and effect, but the rent to be equitably abated as hereinabove
provided, or (ii) give notice to Tenant at any time within thirty (30) days
after such damage terminating this Lease as of a date to be specified in such
notice, which date shall be not less than 30 nor more than sixty (60) days
after giving such notice. In the event of giving of such notice, this Lease
shall expire and all interest of Tenant in the Premises shall terminate on
such date so specified in such notice and the rent reduced by any
proportionate reduction based upon the extent, if any, to which said damage
interfered with the use and occupancy of Tenant, shall be paid to the date of
such termination; Landlord agrees to refund to the Tenant any rent
theretofore paid in advance for any period of time subsequent to such date.

           (c) LANDLORD'S OBLIGATIONS. The Landlord shall not be required to
repair any injury or damage by fire or other cause, or to make any
restoration or replacement of any panelings, decoration, partitions,
ceilings, floor coverings, office fixtures or any other tenant improvements
or property installed in the Premises by Tenant or at the direct or indirect
expense of Tenant. Tenant shall be required to restore or replace same in the
event of damage. Tenant shall have no claim against Landlord for any damage
suffered by reason of any such damage, destruction, repair or restoration.

<PAGE>


           (d) WAIVER BY TENANT. Tenant shall have no right to terminate this
Lease as a result of any statutory provision now or hereafter in effect
pertaining to the damage and destruction of the Premises of the Building,
except as expressly provided herein, and Tenant expressly waives the
provisions of Civil Code Section 1932(2) and Civil Code Section 1933(4) with
respect to any destruction of the Premises. [SEE ADDENDUM SECTION 10.]

     18.   SUBORDINATION. This Lease is subject and subordinate to all ground
or underlying leases, mortgages and deeds of trust which affect the Property
or the Real Property and to all renewals, modification, consolidation,
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, this Lease shall be so, and upon written request of
Landlord to Tenant, Tenant agrees within ten (10) days after Landlord's
request, to 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 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 Building or the Real Property or any renewals,
modification, consolidations, replacements or extensions thereof, provided,
however, that Landlord obtains from the lender or ground lessor a written
undertaking in favor of Tenant to the effect that such lender or ground
lessor will not disturb Tenant's rights of possession under this Lease if
Tenant is not then or thereafter in breach of any covenant or provision of
this Lease.

     19.   EMINENT DOMAIN. If the whole of the Premises 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
("TAKING"), this Lease shall automatically terminate as of the date of such
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 of 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 trade fixtures
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, 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 usable by Tenant bears to the
total area of the Premises.

     20.   DEFAULTS; REMEDIES.

           (a)  DEFAULTS. The following events shall constitute a material
default under this Lease:

                (i)  The vacating or abandonment of the Premises by Tenant.

                (ii) The failure by Tenant to make any payment of rent or any
other payment required to be made by Tenant hereunder, as and when due, or
the failure by Tenant to observe or perform any of the covenants, conditions
or provisions of this Lease to be observed or performed by Tenant, where such
failure shall continue for a period of three (3) days after written notice
thereof from Landlord to Tenant. Such notice need be given only once and may
state in the alternative that Tenant must pay the sum due or perform the
covenant, whichever is applicable, or quit the Premises within said three (3)
day period.

                (iii) The making by Tenant of any general assignment, or
general arrangement for the benefit of creditors, (b) the filing by or
against Tenant of a petition to have Tenant adjudged a bankrupt or a petition
for reorganization or arrangement under any bankruptcy law

                                                                      Landlord

(unless the petition filed against Tenant is dismissed within thirty (30)
days; (c) the appointment of a trustee or receiver to take possession of
substantially all of Tenant's assets located at the Premises or of Tenant's
interest in this Lease, where possession is not restored to Tenant within
thirty (30) days; or (d) the attachment, execution or other judicial seizure
of substantially all of Tenant's assets located at the Premises or of
Tenant's interest in this Lease, where such seizure is not discharged within
thirty (30) days. [SEE ADDENDUM SECTION 11.]

           (b)  REMEDIES. In the event of any such material default, Landlord
may at any time thereafter, and without limiting Landlord in the exercise of
any right or remedy which Landlord may have by reason of such default:

                (i) Landlord has the remedy described in California Civil
Code Section 1951.4 to maintain this Lease in full force and effect and
recover the rent and other monetary charges as they become due, without
terminating Tenant's right to possession irrespective of whether Tenant shall
have abandoned the Premises. In the event Landlord elects not to terminate
the Lease, Landlord shall have the right to attempt to relet the Premises at
such rent and upon such conditions, and for such a term, and to do all acts
necessary to maintain or preserve the Premises as Landlord deems reasonable
and necessary without being deemed to have elected to terminate the Lease
including removal of all persons and property from the Premises: such
property may be removed and stored in a public warehouse or elsewhere at the
cost of and for the account of Tenant. In the event any such reletting
occurs, this Lease shall terminate automatically upon the new tenant taking
possession of the Premises. Notwithstanding that Landlord fails to elect to
terminate the Lease initially. Landlord at any time during the term of this
Lease may elect to terminate this Lease by virtue of such previous default by
Tenant. In the event of such subsequent termination, Landlord shall be
entitled to recover from Tenant all damages incurred by Landlord by reason of
Tenant's default as specified in the following paragraph.

                (ii) Terminate Tenant's right to possession by any lawful
means, in which case this Lease shall terminate and Tenant shall immediately
deliver possession of the Premises to Landlord. In such event Landlord shall
be entitled to recover from Tenant all damages incurred by Landlord by reason
of Tenant's default including without limitation thereto, the following: (1)
the worth at the time of the award of any unpaid rent which had been earned
at the time of such termination: plus (2) 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 (3) the worth at
the time of award of the amount by which the unpaid rent for the balance of
the term after the time of award exceeds the amount of such rental loss that
Tenant proves could be reasonably avoided: plus (4) any other amount
necessary to compensate Landlord for all the detriment approximately caused
by Tenant's failure to perform Tenant's obligations under this Lease or which
in the ordinary course of things would be likely to result therefrom,
(including, without limiting the generality of the foregoing, the amount of
any commission and/or finder's fee for a replacement tenant, and costs to
improve the Premises for a replacement tenant); plus (5) at Landlord's
election, such other amounts in addition to or in lieu of the foregoing as
may be permitted from time to time by applicable California law. Upon any
such re-entry Landlord shall have the right to make any reasonable repairs,
alterations or modifications to the Premises, which Landlord in his sole
discretion deems reasonable and necessary. As used in subparts (i) and (ii)
of this subparagraph (b), the "worth at the time of award" is computed by
allowing interest at the then legal maximum rate of interest for a business
obligation; and, as used in subpart (3) of this subparagraph (b), the worth
at the time of award is computed by discounting such amount at the discount
rate of the U.S. Federal Reserve Bank of San Francisco at the time of award
plus 1%. The term "rent," as used in this Paragraph, shall be deemed to be
and to mean all rentals to be paid pursuant to this Lease and all other

                                                                      Landlord

<PAGE>

                 (iii)  Landlord may, at Landlord's option, retain any or all
of Tenant's property remaining on the Premises, and title thereto shall
thereupon vest in Landlord without the execution of a document of sale or
conveyance by Tenant; or Landlord may remove any or all items of Tenant's
property from the Premises and provided Landlord has given Tenant at least
ten (10) days notice of its intent to do so, dispose of them in any manner
Landlord sees fit, and Tenant shall pay upon demand to Landlord the actual
expense of such removal and disposition together with interest, at the then
maximum interest rate allowed by law for a business obligation, from the date
of payment by Landlord until repayment by Tenant.

                (iv)  Pursue any other remedy now or hereafter available to
Landlord under the laws or judicial decisions of the State of California.

           (c)  LATE CHARGES.  Tenant hereby acknowledges that late payment
by Tenant to Landlord of rent and other sums due hereunder will cause
Landlord to incur costs not contemplated by this Lease, the exact amount of
which will be extremely difficult to ascertain. Such costs include, but are
not limited to, processing and accounting charges, and late charges which may
be imposed on Landlord by the terms of any mortgage or trust deed covering
the Premises. Accordingly, if any installment of rent or any other sum due
from Tenant shall not be received by Landlord within five (5) days after such
amount shall be due, Tenant shall pay to Landlord a late charge equal to ten
percent (10%) of such overdue amount, which shall be additional rent. The
parties hereby agree that such late charge represents a fair and reasonable
estimate of the costs Landlord will incur by reason of late payment by Tenant.

           (d)  PERSISTENT DELINQUENCIES. If Tenant shall be delinquent by
more than fifteen (15) days in the payment of rent on three separate
occasions in any twelve (12) month period, Landlord shall have the right to
terminate this Lease by thirty (30) day written notice given by Landlord to
Tenant within thirteen (13) months of the last such delinquency.

     21.   TRANSFER OF LANDLORD'S INTEREST. If Landlord transfers its
interest in the Premises or in the Real Property, other than a transfer for
SECURITY purposes only, the transferor shall be automatically relieved of any
and all obligations and liabilities on the part of Landlord from and after
the date of such transfer, including without limitation the obligation of
Landlord under Paragraph 5 above to return the security deposit as provided
therein.

     22.   BROKER. In connection with this Lease, Tenant warrants and
represents that it has had dealings only with the broker named in paragraph 1
above 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 does hereby indemnify and agree to hold Landlord, its agents,
partners, representatives, officers, affiliates, shareholders, employees,
successors and assigns harmless from and against any and all loss, liability
and expenses that Landlord may incur should such warranty and representation
prove incorrect, inaccurate or false.

     23.   PARKING. Tenant shall be entitled to rent the number of unreserved
parking space(s) for set forth in Paragraph 1 above in the parking areas as
designated by Landlord. 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.
In addition, to the extent available, Tenant shall have the right to
validation parking in the parking areas designated by Landlord upon terms and
conditions to be established from time to time by Landlord or Landlord's
operator of such parking facilities. Tenant acknowledges that neither
Landlord nor any agent of Landlord has made any representation or warranty as
to the suitability of the parking areas, or as to the availability of parking
spaces, for the conduct of Tenant's business. [SEE ADDENDUM SECTION 5.]

<PAGE>


     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, except by an instrument in writing executed by the
waiving party. 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 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 right to recover all
balances due and owing and to pursue its OTHER rights against Tenant under
this Lease.

     25.   ESTOPPEL CERTIFICATE. Tenant shall from time to time, upon not
less than ten (10) days' prior written notice from Landlord, execute,
acknowledge, and deliver to Landlord a statement in writing certifying
certain facts including, without limitation, 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 so modified, is in full force
and effect) and the dates to which the rental, the security deposit, if any,
and other charges, if any, are paid in advance, and 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 default on the part of
Landlord hereunder, or specifying such defaults, events, or conditions, if
any are claimed. Any prospective purchaser or encumbrancer of the Building
shall be entitled to rely upon any such statement. Tenant's failure to
deliver such statement within such time shall, at the option of Landlord,
constitute a breach or default under this Lease if such option is not so
exercised by Landlord, Tenant's failure shall be conclusive upon Tenant that
(i) this Lease is in full force and effect without modification except as may
be represented by Landlord; (ii) that there are no uncured defaults in
Landlord's performance; and (iii) that not more than two (2) months' rental
has been paid in advance.

     26.   FORCE MAJEURE. This Lease and the obligations of Tenant hereunder
shall not be affected or impaired by reason of unavailability of materials,
strike or other labor troubles or any other cause beyond the reasonable
control or anticipation of Landlord.

     27.   HAZARDOUS WASTE.

           (a)  Tenant shall not cause or permit any Hazardous Material (as
defined in Paragraph 27(c) below) to be brought, kept or used in, on, under
or about the Real Property by Tenant, its agents, employees, contractors, or
invitees. Tenant shall defend, indemnify and hold harmless Landlord, its
agents, partners, officers, employees, successors, assigns, lenders and
insurers from and against any breach by Tenant of the obligations stated in
the preceding sentence, including any and all claims, judgments, damages,
penalties, fines, costs, liabilities, or losses (including, without
limitation, diminution in value of the Building, damages for the loss or
restriction or use of rentable or usable space or of any amenity of the
Building, damages arising from any adverse impact on marketing of space in
the Building, and sums paid in settlement of claims, attorney's 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,

                                                                      Landlord

without limitation, costs incurred in connection with any investigation of
site conditions or any cleanup, remedial, removal, or restoration work
required by any federal, state, or local governmental agency or political
subdivision because of Hazardous Material present in the soil or ground water
on or under the Real Property. Without limiting the foregoing, if the
presence of any Hazardous Material in the Real Property caused or permitted
by Tenant results in any contamination of the Real Property, Tenant shall
promptly, subject to Paragraphs 10 and 11 hereof take all actions, at its
sole expense, as are necessary to return the Real Property to the condition
existing prior to the introduction of any such Hazardous Material.

           (b)  Landlord and Tenant acknowledge that Landlord may become
legally liable for the costs of complying with Laws (as defined in Paragraph
27(d) below) relating to Hazardous Material which are not the responsibility
of Landlord or the responsibility of Tenant, including the following: (i)
Hazardous Material present in the soil or ground water on the Real Property
of which Landlord has no knowledge as of the effective date of this Lease;
(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 this 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 Real Property after the effective date
of this Lease; or Hazardous Material present on or under the Real Property as
a result of any discharge, dumping or spilling (whether accidental or
otherwise) on the Real Property by other lessees of the Real Property 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 Real Property for which Landlord is legally liable
and which are paid or incurred by Landlord shall be an Operating Cost (and
Tenant shall pay Tenant's Proportionate Share thereof in accordance with
Paragraph 4) unless the cost of such compliance, as between Landlord and
Tenant, is made the responsibility of Tenant pursuant to Paragraph 27(a)
above. To the extent any such Operating Cost relating to Hazardous Material
is subsequently recovered or reimbursed, Tenant shall be entitled to a
proportionate reimbursement to the extent it has paid its share of such
Operating Cost to which such recovery or reimbursement relates.

           (c)  As used herein, the term "Hazardous Material" means any
hazardous or toxic substance, material, or waste which is or becomes
regulated by any local governmental authority, the State of California or the
United States Government. The term "Hazardous Material" includes, without
limitation, any material or substance which is (i) defined as "hazardous
waste," "extremely hazardous waste", or "restricted hazardous waste" under

exception set forth in the last sentence of Paragraph 10, and the Premises
all debris and rubbish, all furniture, equipment, business and trade
fixtures, freestanding cabinet work, movable partitioning and other articles
of personal property owned by Tenant or installed or placed by Tenant at its
own expense in the Premises, and all similar articles of any other persons
claiming under Tenant unless Landlord exercises its option to have any
subleases or subtenancies assigned to it, and Tenant shall repair all damage
to the Premises resulting from the installation and removal of such items to
be removed. 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.

     29.   RULES AND REGULATIONS.

           (a)  No sign, advertisement or notice shall be displayed, printed
or affixed on or to the Premises or to the outside or inside of the Building
or so as to be visible from outside the Premises or Building without
Landlord's prior written consent. Landlord shall have the right to remove any
non-approved sign, advertisement or notice, without notice to and at the
expense of Tenant, and Landlord shall not be liable in damages for such
removal. All approved signs or lettering on doors and walls shall be printed,
painted, affixed or inscribed at the expense of Tenant by Landlord or by a
person selected by Landlord and in a manner and style acceptable to Landlord.
Landlord's acceptance of any name for listing on the Building Directory will
not be deemed, nor will it substitute for, Landlord's consent, as required by
this Lease, to any sublease, assignment, or other occupancy of the demised
premises.

           (b)  Tenant shall not obtain for use on the Premises ice, drinking
water, waxing, cleaning, interior glass polishing, rubbish removal, towel or
other similar services, or accept barbering or bootblacking, or coffee cart
services, milk, soft drinks or other like services on the Premises, except

fixed by Landlord. No vending machines or machines of any description shall
be installed, maintained or operated upon the Premises without Landlord's

apparatus shall not be used for any purpose other than for which they were
constructed and no foreign substance of any kind whatsoever shall be thrown

by law, or any machinery or equipment which shall cause excessive vibration
to the Premises or noticeable vibration to any other part of the Building.
All office equipment of any electrical or mechanical nature shall be place by
Tenants

vibration, noise, or annoyance. Prior to bringing any heavy safes, vaults,
large computers or similarly heavy equipment into the Building, Tenant shall
inform Landlord in writing of the dimensions and weight thereof and shall
obtain Landlord's consent thereto, which consent Landlord shall have the
right to deny. Such consent shall not constitute a representation or warranty
by Landlord that the safe, vault or other equipment complies, with regard to
distribution of weight and/or vibration, with the provisions of this Rule (f)
nor relieve Tenant from responsibility for the consequences of such
non-compliance, and any such safe, vault or other equipment which Landlord
determines to constitute a danger of damage to the Building or a nuisance to
other Tenants, either alone or in combination with other heavy and/or
vibrating objects and equipment, shall be promptly removed by Tenant upon
Landlord's written notice of such determination and demand for removal
thereof.

without the prior written consent of Landlord. Tenant shall pay the cost of
all electricity used for air conditioning in the Premises if such electrical
consumption exceeds normal office requirements, regardless of whether
additional apparatus in installed pursuant to the preceding sentence.

           (k)  The Premises shall not be used for manufacturing or for the
storage of merchandise except as such storage may be incidental to the
permitted use of the Premises. Tenant shall not, without Landlord's prior
written consent, occupy or permit any portion of the Premises to be occupied

thereof, gives written approval, and is furnished a key therefor. Each Tenant
must, upon the termination of his tenancy, give to Landlord all keys of
stores, offices or toilets or toilet rooms, either furnished to, or otherwise
procured by, such Tenant, and in the event of the loss of any keys so
furnished such Tenant shall pay Landlord the cost of replacing the same or of
changing the lock or locks opened by such lost key if Landlord shall deem it
necessary to make such change.

           (p)  Landlord shall have the right to prohibit any advertising by
any Tenant which, in Landlord's opinion, tends to impair the reputation of

advertising.

other provision of this Lease and such other provisions shall remain in full
force and effect. This Lease and the exhibits and any rider attached hereto
constitute the entire agreement between Landlord and Tenant with respect to
the subject matter hereof, and no prior agreement, understanding or

possession of the Premises, the losing party shall pay the successful party a
reasonable sum for attorneys' fees in such suit and such attorneys fees shall
be deemed to have accrued on the commencement of such action and shall be

the act of or notice from or notice or refund to, or the signature of, any
one or more of them, with respect to the tenancy or this Lease, shall be
binding upon each of them, with the same force and effect as if each of them
had so acted or so given or received such notice or refund or so signed.

                                      28                              ________
                                                                        Tenant
                                                                      ________
                                                                      Landlord

<PAGE>

         2.       GENERATOR AND SUPPLEMENTAL AIR CONDITIONING UNITS. Landlord
shall provide to Tenant the exclusive use of (i) generator located in the
rooftop parking area, and (ii) the two existing supplemental air-conditioning
units located on the balcony of the sixth (6th) floor that exists at the
Building and the Premises as of the signing of this Lease. Tenant shall
accept the equipment is its absolute as-is condition, and Landlord makes no
warranty, express or implied, as to the condition and operation of such
equipment. Landlord shall not be responsible to Tenant, its employees,
agents, guests as a result of Tenant's usage of the equipment described
herein, and Tenant shall indemnify and hold Landlord and Landlord's employees
and agents harmless from any and all claims, demands, liabilities, causes of
action, costs and attorney's fees arising from Tenant's usage of such
equipment.

         Tenant shall be solely responsible for the service, maintenance, and
repairs of the equipment, and shall comply with any and all Federal, State and
Local governing authorities at Tenant's sole cost and expense.

         Notwithstanding the foregoing, in the event that, within fourteen (14)
days following the mutual execution and delivery of this Lease, Tenant
determines that the afore-mentioned generator is not operational or is
materially defective, Tenant may deliver written notice to Landlord that Tenant
has elected to terminate all of its rights and obligations hereunder relating to
such generator.

         3.       ABOVE-STANDARD ELECTRICAL. In the event that Tenant's
electrical usage at the Premises (which are not separately metered and
separately charged to Tenant) exceeds the standard usage of office tenants in
the Building ("Standard Electrical Usage") whether due to the extended hours
of Tenant's operations and/or high usage by Tenant during normal business
hours, Landlord shall require that all or part of the electrical usage at the
Premises that is not separately metered, shall be separately metered at
Tenant's sole cost and expense, in order to determine the amount of
electrical usage which is in excess of Standard Electrical Usage limits.
Tenant shall pay to Landlord actual costs of any excess electrical usage plus
a reasonable administrative fee not to exceed 10% of the actual costs. The
parties agree that separate metering will be made for the use of the
supplemental air conditioning units described in section 2 above and for
aspects of the Premises set forth in the approved plans.

         4.       CAP ON DIRECT COST INCREASES. Notwithstanding the terms of
Paragraph 4, Direct Costs for any given calendar year following 2000 shall
not exceed the Base Costs increased at a compounded rate of ten percent (10%)
each year, starting with the year 2001. To illustrate the foregoing, if Base
Costs per rentable square foot of the Building were $10.20, the maximum
Direct Costs per rentable square foot of the Building would be $11.22 for
2001, $12.34 for 2002, $13.58 for 2003 and $14.93 for 2004.

         5.       PARKING. One parking space shall be deducted from Tenant's
parking allotment set out under Section 1(f) of this Lease for the purpose of
accommodating the generator provided to Tenant under Section 2 of this
Addendum, provided rent for the use of such space for the generator shall be
paid for by Tenant to Landlord at the prevailing reserved parking rate.

         6.       CONSUMER PRICE INDEX ADJUSTMENT (PARAGRAPH 4). The Basic
Rent shall not be increased under Section 4 of the Lease until January 1,
2001 according to the provisions of this section.

         7.       USE (PARAGRAPH 8). Tenant's obligations under Section 8 of
the Lease shall exclude structural work to the Building or work to the
systems of the Building, unless such work is required by Tenant's
improvements or Tenant's use in excess of normal office improvements or
normal office use.


                                      29                              ________
                                                                        Tenant
                                                                      ________
                                                                      Landlord

<PAGE>

         8.       REPAIRS AND ALTERATIONS (PARAGRAPH 10). Landlord's
satisfaction shall be reasonable under this Section. Landlord may make any
repairs which are not made by Tenant within twenty (20) days of receiving
written notice from Landlord (or immediately in emergency) and charge Tenant
for the cost thereof which costs shall be paid by Tenant within five (5) days
from invoice by Landlord. Prior to the installation of any alteration
hereunder Tenant may request that Landlord elect whether Landlord shall (i)
require such alteration to remain with the Premises at the end of the Lease
Term; (ii) require such alteration to be removed or remain at the end of the
Lease Term. If so requested by Tenant, Landlord shall make such election
prior to Tenant's installation of the alterations. Landlord may not require
Tenant to remove any alterations or installations made by Landlord on
Tenant's behalf or by Tenant as part of the Tenant Improvements to the
Premises made pursuant to the Work Letter attached hereto as Exhibit B;
except that, at Landlord's discretion, Tenant shall be required to remove
those improvements exceeding Building standards (e.g., raised flooring,
electrical wiring and cabling, soundproofing).

         9.       ASSIGNMENT AND SUBLETTING (PARAGRAPH 16). As used herein

Landlord prior written notice of any such assignment or sublease and promptly
supplies Landlord with any documents or information reasonably required by
Landlord regarding such assignment or sublease or such Affiliate Transferee;
(B) that such assignment or sublease is not a subterfuge by Tenant to avoid
Tenant's obligation to obtain consent or pay the rental profits required
hereunder; and (C) the assignor remains fully liable for the obligations of
Tenant hereunder and the Affiliate Transferee assumes full liability for the
Tenant's obligation hereunder. Tenant shall pay Landlord's reasonable costs

         In the event Tenant contemplates a transfer of all or a portion of the
Premises as provided in the Lease or this Addendum, Tenant shall give Landlord
written notice of such contemplated transfer and, notwithstanding all other
rights of Landlord hereunder, if such transfer is an assignment or a sublease of
all of substantially all of the Premises, Landlord shall have the right to

delivery of written notice making such election to Tenant within ten (10)
business days following receipt of such notice from Tenant.

Within sixty (60) days following any damage or destruction that prevents
access to or renders more than twenty five percent (25%) of the Premises
untenantable, Landlord shall give Tenant written notice of stating the
estimated time for the restoration of the Premises or access thereto, and if
such estimated time is exceeds 120 days, Tenant shall have the right to
terminate this Lease by giving Landlord notice within ten (10) business days
of receiving Landlord's notice.

         11.      DEFAULTS (PARAGRAPH 20). Tenant's vacating of the Premises
for less than thirty (30) days shall not constitute a material default under
the Lease. Tenant shall have thirty (30) days after written notice from
Landlord to Tenant to cure non-monetary defaults. The three (3) day period
under this section of the Lease shall mean three (3) business days.

         12.      HAZARDOUS WASTE (PARAGRAPH 27). Tenant shall not be
obligated to pay directly for costs related to use, presence or release of
Hazardous Waste within the meaning of this Lease unless such use, presence or
release is attributable to Tenant or Tenant's agents, contractors or
invitees. Costs relating the use, presence or release of Hazardous Waste in
the Building may be included in Operating Costs provided that costs incurred
due to the failure of the Building to comply, as of the mutual execution and
delivery of this Lease with federal state or local laws relating to Hazardous
Materials, shall not be included in Operating Costs and costs incurred due to
Landlord failure to comply such laws related to Hazardous Materials shall not
be included in Operating Costs.

         13.      RULES AND REGULATIONS (PARAGRAPH 29). Where Landlord's
consent is required under this section of the Lease, Landlord's consent shall
not be unreasonably withheld.

         14.      GENERAL PROVISIONS (PARAGRAPH 31). Under section (f) of
this Paragraph, Landlord will use commercially reasonable efforts to minimize

                  operate two (2) video cameras (small portable size) ("Video
                  Cameras") on the balcony of the Premises. The placement of
                  the Video Cameras shall be reasonably approved by Landlord
                  in writing following Tenant's submission of plans and
                  specifications to Landlord. Such installation and operation
                  shall be subject to all the terms and conditions of this
                  Lease. Tenant shall indemnify and hold Landlord and
                  Landlord's employees and agents harmless from any and all
                  claims, demands, liabilities, causes of action, costs and
                  attorney's fees arising from Tenant's usage of such
                  equipment. Tenant shall be solely responsible for the
                  service, maintenance, and repairs of the equipment, and
                  comply with any and all Federal, State and Local governing
                  authorities at Tenant's sole cost and expense.

         16.      ELECTRICAL INTERRUPTION. To the extent that Landlord may

                  interruption to the Building that is required by Landlord
                  or brought to Landlord's attention by proper notice,
                  Landlord will use commercially reasonable efforts to notify
                  Tenant of such scheduled electrical power interruption. In
                  no event shall Landlord have any liability to Tenant for
                  any reason whatsoever for Landlord's failure to notify
                  Tenant and Tenant hereby waives all claims based thereon.

         17.      BROADCAST INTERNET AND WEBSITE USE. In no event shall
Landlord's consent to permit broadcast internet and website operations at the
Premises impose any obligation on Landlord to perform any work to the
Premises or Building in order to accommodate such operations nor shall
Landlord incur any costs or obligations in connection with obtaining any
necessary permits or governmental authorizations required to permit such
operations at the Premises.

THIS TENANT WORKLETTER shall set forth the terms and conditions relating to
the construction of the tenant improvements in the Premises. This Tenant Work
Letter is essentially organized chronologically and addresses the issues of
the construction of the Premises, in sequence, as such issues will arise
during the actual construction of the Premises. All references in this Tenant
Work Letter to Articles or Sections is attached as Exhibit "B" and of which

                     CONSTRUCTION DRAWINGS FOR THE PREMISES

Subject to the Maximum Allowance, Landlord shall construct the improvements in
the Premises (the "Tenant Improvements") pursuant to the space plan and
improvement specifications (the "Approved Improvement Plan") agreed to between
Landlord and Tenant, which agreement both parties shall use their best efforts
to reach within thirty (30) days following the Commencement Date. Tenant shall
make no changes or modifications to the Approved Improvement Plan without the
prior written consent of Landlord, which consent may be withheld in Landlord's
sole discretion if such change or modification would directly or indirectly
delay the "Substantial Completion", as that term is defined in Section 5 of this
Tenant Work Letter, of the Premises or increase the cost of designing or
constructing the Tenant Improvements. Notwithstanding that Landlord may have
reviewed and approved the Approved Improvement Plan, Landlord shall have no
liability whatsoever in connection therewith and shall not be responsible for
any omissions or errors contained in the Approved Improvement Plan, and Tenant's
waiver and indemnity set forth in this Lease shall specifically apply to the
Approved Improvement Plan. In no event shall Landlord be required to incur costs
and expenses in connection with the in excess of Two Hundred Seventy Five
Thousand One Hundred Fifty Four Dollars and Zero/100's ($275,154) (the "Maximum
Allowance") in performing the Tenant Improvements,, which costs shall include,
without limitation, architectural fees, space planning, permit applications and
design-related fees.

                              OVER-ALLOWANCE AMOUNT

In the event that it is reasonably determined by Landlord that the costs of
the Tenant Improvements will exceed the Maximum Allowance, or, after the
agreement of the Approved Improvement Plan, Tenant requests any changes
thereto which result in any costs in excess of the Maximum Allowance, all
such excess costs shall be estimated by Landlord and paid by Tenant to
Landlord immediately upon Landlord's request (the "Over-Allowance Amount").
The Over-Allowance Amount shall be disbursed to Landlord prior to the
disbursement of any portion of Landlord's contribution to the construction of
Tenant Improvements.

                                    Section 3

the extent reasonably necessary to allow Tenant to pursue the particular
claim against the Contractor, all warranties and guaranties by the contractor
who constructs the Tenant Improvements (the "Contractor") relating to the
Tenant Improvements, and Tenant hereby waives all claims against Landlord
relating to, or arising out of the construction of, the Tenant Improvements.

arising from the actions of Tenant's space planner/architect on the Premises
or the Building. In addition, immediately after the Substantial Completion of
the Premises, Tenant shall have prepared and delivered to the Building a copy

drawings) for the Tenant Improvements.

            COMPLETION OF THE TENANT IMPROVEMENTS; COMMENCEMENT DATE

         (a) READY FOR OCCUPANCY. The Premises shall be deemed "Ready for
Occupancy" upon the Substantial Completion of the Initial 6th Floor Work, the

of construction of the Tenant Improvements in the applicable portion of the

punch list items and any tenant fixtures, work-stations, built-in furniture, or
equipment to be installed by Tenant under the supervision of Contractor.

         (b) DELAY OF THE SUBSTANTIAL COMPLETION OF THE PREMISES. Except as
provided in this Section 5(b), the Commencement Date shall occur as set forth in
the Lease and Section 5(a), above. If there shall be a delay or there are delays
in the Substantial Completion of the applicable portion of the Premises or in
the occurrence of any of the other conditions precedent to the Commencement
Date, as set forth in the Lease, as a direct, indirect, partial, or total result
of:

approval;

         (ii) A breach by Tenant of the terms of this Tenant Work Letter or the
Lease;

         (iii) Tenant's request for changes in the Approved Improvement Plan;

         (iv) Changes in any of the Approved Improvement Plan because the
same do not comply with applicable laws;

         (v) Tenant's requirement for materials, components, finishes or
improvements which are not available in a commercially reasonable time given the
anticipated date of Substantial Completion of the Premises, as set forth in the
Lease, or which are different from, or not included in, Landlord's standard
improvement package items for the Building;

         (vi) Changes to the base, shell and core work of the Building required
by the Approved Improvement Plan; or

         (vii) Any other acts or omissions of Tenant, or its agents, or
employees; then notwithstanding anything to the contrary set forth in the Lease
or this Tenant Work Letter and regardless of the actual date of the Substantial
Completion of the Premises, the Commencement Date shall be deemed to be the date
the Commencement Date would have occurred if no Tenant delay or delays, as set
forth above, had occurred.


                                      35                              ________

Premises as permitted by the terms of this Section 6(a), Tenant shall submit a
schedule to Landlord and Contractor, for their approval, which schedule shall

calendar days. In all instances where Tenant is required to approve or deliver
an item, if no written notice of approval is given or the item is not delivered
